PRELIMINARY PROXY STATEMENT/PROSPECTUS, SUBJECT TO COMPLETION,
DATED MAY 8, 2026

PROXY STATEMENT FOR EXTRAORDINARY GENERAL MEETING IN LIEU OF AN ANNUAL
GENERAL MEETING OF SHAREHOLDERS OF MOUNTAIN LAKE ACQUISITION CORP.

AND
PROSPECTUS FOR

55,468,670 SHARES OF CLASS A COMMON STOCK

AND

5,805,638 SHARES OF CLASS B COMMON STOCK

OF AVALANCHE TREASURY CORPORATION

To the Shareholders of Mountain Lake Acquisition Corp. (“MLAC Shareholders”):

You are cordially invited to attend the extraordinary general meeting in lieu of an annual general meeting (the “Meeting”) of the shareholders of Mountain Lake Acquisition Corp., a Cayman Islands exempted company (“MLAC”), which will be held at              , Eastern Time, on           , 2026. The Meeting will be held at 1345 Avenue of the Americas, New York, NY 10105 and virtually over the Internet by means of a live audio webcast. You or your proxyholder will be able to attend and vote at the Meeting in person or by visiting https://www.cstproxy.com/mountainlakeacquisition/2026 and using a control number assigned by Continental Stock Transfer & Trust Company. To register and receive access to the Meeting, registered shareholders and beneficial owners (those holding shares through a stock brokerage account or by a bank or other holder of record) will need to follow the instructions applicable to them provided in this proxy statement/prospectus. This proxy statement/prospectus includes additional instructions on how to access the Meeting and how to listen, vote and submit questions from home or any remote location with Internet connectivity.

MLAC is a Cayman Islands exempted company incorporated as a blank check company for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities, which we refer to as an “acquisition target.”

On October 1, 2025, MLAC, Avalanche Treasury Corporation, a Delaware corporation (“Pubco”), Avalanche SPAC Merger Sub LLC, a Delaware limited liability company (“MLAC Merger Sub”), Avalanche Company Merger Sub LLC, a Delaware limited liability company (“Company Merger Sub”, and together with MLAC Merger Sub, the “Pubco Subsidiaries”), Avalanche Treasury Company LLC, a Delaware limited liability company (the “Company” or “AVAT”) and Dragonfly Digital Management, LLC, a Delaware limited liability company (“Seller”) entered into a business combination agreement (as amended, restated or otherwise modified from time to time, the “Business Combination Agreement”).

Pursuant to the Business Combination Agreement, and subject to the terms and conditions set forth therein, upon the consummation of the transactions contemplated thereby (the “Closing” and the date and time at which the Closing is actually held, the “Closing Date”), (a) prior to the Closing, MLAC will effect a domestication under Section 388 of the General Corporation Law of the State of Delaware (the “DGCL”) and Section 206 of the Cayman Act (the “Domestication”), pursuant to which MLAC will transfer by way of continuation to and become a Delaware corporation, (b) at least two hours after the Domestication, MLAC Merger Sub will merge with and into MLAC in accordance with the applicable provisions of the DGCL and the and the Limited Liability Company Act of the State of Delaware (the “DLLCA”), with MLAC continuing as the surviving company and a wholly-owned subsidiary of Pubco (the “MLAC Merger”) and with MLAC Shareholders receiving one share of non-voting Class A common stock, par value $0.01 per share, of Pubco (“Pubco Class A Stock”) for each Class A ordinary share, par value $0.0001 per share, of MLAC (the “MLAC Class A Ordinary Shares”) held by such shareholder, and with each holder of MLAC Rights receiving one share of Pubco Class A Stock in exchange for every ten (10) MLAC Rights held by such holder and (c) Company Merger Sub will merge with and into the Company in accordance with the applicable provisions of the DLLCA, with the Company continuing as the surviving company (the “Company Merger” and, together with the MLAC Merger, the “Mergers” and, together with the other transactions contemplated by the Business Combination Agreement, including the Foundation Transaction, the Dragonfly Contribution and the Company Unit Subscription, in each case as defined herein, the “Transactions”), and with (i) each Company Member other than Seller receiving one share of Pubco Class A Stock for each Company Unit held immediately prior to the effective time of the Company Merger and (ii) Seller receiving one share of Pubco Class A Stock and one share of Pubco Class B common stock, par value $0.01 per share (“Pubco Class B Stock” and, together with the Pubco Class A Stock, the “Pubco Stock”), for each Company Unit it holds. As a result of the Mergers and the other transactions contemplated by the Business Combination Agreement, upon the terms and subject to the conditions set forth in the Business Combination Agreement and in accordance with applicable law, Pubco will become a publicly traded company.

On January 13, 2026 and on March 17, 2026, MLAC, Pubco, the Pubco Subsidiaries, the Company, Dragonfly Ventures L.P. and Dragonfly Ventures II, L.P. (the “Funds” or “DVs”) and together with other Seller controlled vehicles (the “Seller Related Parties”) and Astral Horizon, L.P., a Delaware limited partnership (“Astral”) entered into certain amendments to the Business Combination Agreement, effective as of October 1, 2025.

The information in this preliminary proxy statement/prospectus is not complete and may be changed. The registrant may not sell or issue these securities offered by this preliminary proxy statement/ prospectus until the registration statement filed with the Securities and Exchange Commission, of which this proxy statement/prospectus is a part, is declared effective. This preliminary proxy statement/prospectus does not constitute an offer to sell these securities and it is not soliciting an offer to buy these securities in any state or other jurisdiction where the offer or sale is not permitted.

Astral is a Delaware limited partnership whose general partner is Astral Horizon GP, LLC. The limited partners of Astral are certain senior managers and employees of the Seller and the general partners of the DVs. Astral Horizon GP, LLC is managed by some of the same individuals who serve as the managers of the general partners of the DVs. Accordingly, Astral is a related party to the Seller Related Parties by virtue of common management and overlapping ownership among their respective principals. The 4,000,000 newly issued Pubco Class A Stock Astral is entitled to receive as additional consideration for the Company Merger (the “Additional Merger Consideration Shares”) are being issued to Astral in consideration for advisory and strategic services provided by Astral’s limited partners in connection with the structuring and execution of the Business Combination and the establishment of Pubco. Such services included, but were not limited to:

(i) Executive Recruitment: Astral’s limited partners assisted in identifying, evaluating, and recruiting the Chief Executive Officer of Pubco; and

(ii) Tax and Corporate Structuring Advisory: Astral’s limited partners provided strategic advice regarding aspects of the tax and corporate structuring of the Business Combination and post-Closing operations of Pubco.

Consequently, (i) on January 13, 2026, the Parties entered into the First Amendment to the Business Combination Agreement, pursuant to which, inter alia, the 4,000,000 Additional Merger Consideration Shares (i.e., the 2,000,000 Astral Post-Closing Shares and the 2,000,000 Astral Earnout Shares) will be issued, on the Company Merger Effective Date, to Astral (the Astral Earnout Shares being held in escrow for the Escrow Period only to be released in accordance with the Astral Escrow Agreement); and (ii) on March 17, 2026, the Parties entered into the Second Amendment to the Business Combination Agreement, pursuant to which the issuance by Pubco to Astral of the 2,000,000 Astral Post-Closing Shares will occur on the thirtieth (30th) calendar day following the Closing Date, rather than on the Company Merger Effective Date.

Concurrently with the signing of the Business Combination Agreement, on October 1, 2025, Pubco, the Company and MLAC entered into the Company Unit Subscription Agreements with the Company Unit Investors, pursuant to which the Company Unit Investors agreed to purchase, payable in cash, USD Coin (“USDC”) or AVAX (or a combination of cash, USDC and/or AVAX), and the Company agreed to issue and sell, approximately $216 million worth of Company Class A units (the “Company Units”) at a price of $10.00 per Company Unit, in a private placement (the “Company Unit Subscription”), upon the terms and subject to the conditions set forth therein. Company Unit Investors received a number of Company Units equal to, (a) if the Company Unit Investor elected to purchase Company Units by contributing AVAX, the stated AVAX amount (“Stated AVAX Amount”) multiplied by the applicable signing AVAX price (“Applicable Signing AVAX Price”), or, (b) if the Company Unit Investor elected to purchase the Company Units by contributing cash or USDC, the stated dollar amount (“Stated Dollar Amount”) or the stated USDC amount (“Stated USDC Amount”) (as applicable), in each case divided by $10.00 (the “Per Unit Price”).

Each Company Unit Investor was required to fund its respective cash or USDC within three business days following the execution date of the Company Unit Subscription Agreement, and to fund its respective AVAX as soon as reasonably possible after the execution date of the Company Unit Subscription Agreement, in any case on or prior to November 7, 2025, in accordance with the terms of the Company Unit Subscription Agreements. At the Company Merger Effective Time, each Company Unit held by Company Unit Investors will be converted automatically into one share of Pubco Class A Stock.

Concurrently with the execution of the Business Combination Agreement and the TSA (as defined herein), Seller, Company, Pubco, Avalanche (BVI), Inc., a company incorporated in the British Virgin Islands (“Avalanche BVI”) and Avalanche Cayman, a Cayman Islands exempted company (“Avalanche Cayman” and together with Avalanche BVI, the “Foundation”) entered into an asset sale and contribution agreement (the “Contribution Agreement”), pursuant to which, on the date of the Business Combination Agreement: (a) the Foundation agreed to sell a minimum of $200 million of AVAX tokens on a pre- discount basis to Company on the terms and subject to the conditions set forth in a Token Sale Agreement (the “TSA”) by and between Company and the Foundation (the “Foundation Transaction”), and (b) Seller agreed to contribute, directly and indirectly through Dragonfly Ventures L.P. and Dragonfly Ventures II, L.P. (the “Funds”) and together with other Seller controlled vehicles (the “Seller Related Parties”), 1,960,040 AVAX in exchange for 5,805,638 Company Units at the Per Unit Price, with an approximate value of $58 million (the “Dragonfly Contribution”).

Concurrently with the execution of the Business Combination Agreement and the Contribution Agreement, the Company, Pubco, the Foundation entered into the TSA, pursuant to which, on the date of the Business Combination Agreement, the Foundation agreed to sell a minimum of $200 million of AVAX tokens on a pre-discount basis to the Company in exchange for, at a 60% discount, (i) $50 million in cash or USDC and (ii) $30 million in the form of up to 3,000,000 shares of Pubco Class A Stock (the “Foundation Shares”). If at any time following the Closing Date, the Pubco Class A Stock cease to be nonvoting securities and at such time the Foundation owns a number of Foundation Shares in excess of 4.7% of the then-outstanding Pubco Class A Stock (the

“Maximum Percentage”), the Foundation may request to exchange the number of Foundation Shares in excess of the Maximum Percentage for an equal number of pre-funded warrants convertible, at the Foundation’s request, into Pubco Class A Stock on a one-to-one basis, and the Company shall issue such number of pre-funded warrants convertible into Pubco Class A Stock in exchange for Foundation Shares in excess of the Maximum Percentage, prior to the time the Pubco Class A Stock converts into voting securities. The AVAX tokens delivered pursuant to the Foundation Transaction are subject to certain restrictions for 5 years following the date of the TSA.

Concurrently with the execution of the Business Combination Agreement, MLAC entered into a Sponsor Support Agreement with Mountain Lake Acquisition Sponsor LLC (the “Sponsor”) and Pubco (the “Sponsor Support Agreement”), pursuant to which, among other things, the Sponsor agreed (i) to vote its MLAC Class A Ordinary Shares and Class B ordinary shares, par value $0.0001 per share, of MLAC (the “MLAC Class B Ordinary Shares” and together with the MLAC Class A Ordinary Shares, the “MLAC Ordinary Shares”) in favor of the Business Combination Agreement, the Transactions and the Business Combination Proposal, (ii) to vote its MLAC Ordinary Shares against any alternative transactions, (iii) to comply with the restrictions imposed by the letter agreement, dated as of December 12, 2024 (the “Insider Letter”), by and among MLAC, the Sponsor and the officers and directors of MLAC at the time of its initial public offering, including the restrictions on transfer and redemption of MLAC Ordinary Shares in connection with the Transactions, and (iv) subject to and conditioned upon the Closing, to waive any anti-dilution rights that would otherwise result in the MLAC Class B Ordinary Shares converting into MLAC Class A Ordinary Shares on a greater than one-for-one basis.

In addition, the Sponsor agreed to effect certain security cancellations and to deposit certain Pubco Class A Stock issued to it at Closing into escrow in connection with the Closing. Specifically, (i) immediately prior to the MLAC Merger Effective Time, the Sponsor will deliver to MLAC for cancellation 495,000 MLAC Private Placement Shares and 4,387,500 MLAC Founder Shares, and (ii) at the Closing 1,600,000 shares of Pubco Class A Stock will be issued to the Sponsor (of the total 2,800,000 shares to be issued to the Sponsor as a result of the MLAC share conversion) (the “Sponsor Earnout Shares”) and deposited into an escrow account with Continental Stock Transfer and Trust Company. The Sponsor Earnout Shares will be released to the Sponsor in tranches pursuant to the Sponsor Support Agreement and an escrow agreement that shall be in a form to be mutually agreed upon by the Sponsor, Seller, Pubco and the escrow agent prior to the Closing (the “Sponsor Escrow Agreement”). The Sponsor agreed that all of the Sponsor Earnout Shares, together with any shares received upon equitable adjustment of the Sponsor Earnout Shares, shall be subject to potential transfer to Pubco (the “Sponsor Transfer”) at the end of the earnout period in the event that not all of the triggering events are achieved by Pubco.

Concurrently with the Closing, MLAC, the Sponsor and the MLAC Insiders will enter into a Lock-Up Agreement with Pubco (the “Sponsor Lock-Up Agreement”), and certain holders of shares of Pubco Stock will also enter into a Lock-Up Agreement with Pubco in substantially the same form as the Sponsor Lock-Up Agreement (the “Seller Lock-Up Agreement,” collectively with the Sponsor Lock-Up Agreement, the “Lock-Up Agreements”), pursuant to which such parties will agree that the shares of Pubco Class A Stock received by them in connection with the Business Combination, and any other securities convertible into or exercisable or exchangeable for Pubco Stock, will be subject to transfer restrictions, as described below, with certain customary exceptions.

Concurrently with the Closing, Pubco, MLAC, the Sponsor, Seller, Avalanche BVI, Avalanche Cayman and certain security holders shall enter into an amended and restated registration rights agreement, which will add Pubco as a party (the “Amended and Restated Registration Rights Agreement”), and which provides for customary demand registration rights, piggyback registration rights and shelf registration rights for the benefit of the holders of Pubco Stock named therein, including the Sponsor, Seller and the Foundation, subject to customary cutbacks and issuer suspension rights. The Amended and Restated Registration Rights Agreement also includes customary provisions relating to underwriting participation, registration expenses, indemnification and coordination of sales in underwritten offerings, and will become effective upon the Closing and will supersede MLAC’s existing registration rights agreement in its entirety.

Upon the completion of the Transactions, the Seller and the Seller Related Parties will be issued 5,805,638 shares of Pubco Class A Stock and 5,805,638 shares of Pubco Class B Stock.

Upon the completion of the Transactions, and assuming, among other things, that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination, that no shares of Pubco Class A Stock are issued pursuant to the Pubco 2026 Omnibus Incentive Plan to be adopted prior to Closing, as amended from time to time (the “Incentive Plan”) and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements, (i) Public Shareholders (including MLAC Right Holders), (ii) the Company Unit Investors, (iii) the Sponsor and its Affiliates, (iv) the Foundation, (v) Astral and (vi) Seller Related Parties will own approximately 41.8%, 35.7%, 4.6%, 5.0%, 3.3% and 9.6% of the issued and outstanding shares of Pubco Class A Stock, respectively, and approximately 0%, 0%, 0%, 0%, 0% and 100% of the issued and outstanding shares of Pubco Class B Stock, respectively. Assuming that no Public Shareholders exercise redemption rights with

respect to their Public Shares upon completion of the Business Combination, the aggregate value of consideration the Public Shareholders (including MLAC Right Holders) will receive is $253,000,000 consisting of 25,300,000 shares of Pubco Stock; the aggregate value of consideration the MLAC Right Holders will receive is $23,000,000 consisting of 2,300,000 shares of Pubco Stock; the aggregate value of consideration the Public Shareholders (exclusive of the MLAC Right Holders) will receive is $230,000,000 consisting of 23,000,000 shares of Pubco Stock; and the aggregate value of consideration Astral will receive is $40,000,000 consisting of 4,000,000 shares of Pubco Stock.

Each holder of shares of Pubco Class A Stock will have no voting rights, except (i) as required by the DGCL or (ii) on any matter that adversely affects them relative to holders of any other class of stock of Pubco, until all shares of Pubco Class B Stock are canceled. Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights. Each holder of shares of Pubco Class B Stock will be entitled to one vote for each share of Pubco Class B Stock held of record by such holder on all matters on which stockholders are generally entitled to vote. Therefore under the above assumptions, (i) Public Shareholders (including MLAC Right Holders), (ii) the Company Unit Investors, (iii) the Sponsor and its Affiliates, (iv) the Foundation, (v) Astral and (vi) Seller Related Parties will have approximately 0%, 0%, 0%, 0%, 0% and 100% of the voting power of Pubco, respectively, following the Business Combination.

The price per share of Pubco Class A Stock is $10.00 for (i) Public Shareholders (including MLAC Right Holders), (ii) the Company Unit Investors, (iii) the Sponsor and its Affiliates, (iv) the Foundation, (v) Astral and (vi) Seller Related Parties. The value of the consideration that the Public Shareholders are each receiving in connection with the Business Combination is thus $10.00 per share.

The aggregate value of the total consideration that the Sponsor and its Affiliates will receive, comprising shares of Pubco Class A Stock valued at $10.00 per share, is $28,000,000, assuming, among other things, that all Sponsor Earnout Shares are released from Escrow to the Sponsor and that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination.

Pursuant to the Business Combination Agreement, Seller will receive an equal number of shares of both Pubco Class A and Pubco Class B Stock equal to the dollar value of 1,960,040 AVAX pursuant to the Contribution Agreement, using the Signing Price, divided by $10.00. The value of the total consideration that Seller and its affiliates will receive, comprising an equal number of shares of Pubco Class A Stock and Pubco Class B Stock, together valued at $10.00 per share, is $58,056,384.

On the basis of the foregoing and with the price per share of Pubco Class A Stock assumed at $10.00, the aggregate value of the consideration in Pubco Stock offered pursuant to this registration statement is $554,686,704, comprising $230,000,000 consisting of 23,000,000 shares of Pubco Stock to the Public Shareholders (exclusive of the MLAC Right Holders); $23,000,000 consisting of 2,300,000 shares of Pubco Stock to the MLAC Right Holders; $28,000,000 consisting of 2,800,000 shares of Pubco Stock to the Sponsor and its Affiliates; $58,056,384 consisting of 5,805,638 shares of Pubco Class A Stock and 5,805,638 shares of Pubco Class B Stock to the Seller Related Parties and $215,630,320 consisting of 21,563,032 shares of Pubco Stock to the Company Unit Investors.

Proposals to approve the Business Combination Agreement and the other matters discussed in this proxy statement/prospectus will be presented at the Meeting scheduled to be held on            , 2026.

The MLAC Class A Ordinary Shares, MLAC Units and the MLAC Share Rights are currently listed on The Nasdaq Global Market under the symbols “MLAC,” “MLACU” and “MLACR,” respectively. If Pubco’s application for listing is approved, shares of Pubco Class A Stock are expected to be traded on Nasdaq under the symbol “AVAT” at the Closing. The MLAC Class A Ordinary Shares, MLAC Units and MLAC Share Rights will not trade after the Closing.

Each of MLAC and Pubco is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has elected to comply with certain reduced public company reporting requirements. Pubco is, and will be, after the consummation of the Business Combination, considered a “controlled company” under Nasdaq Rules, and may be exempt from certain corporate governance requirements thereunder.

When holders (the “Public Shareholders”) of MLAC Class A Ordinary Shares issued in the initial public offering of MLAC (the “MLAC IPO” and such shares, the “Public Shares”) consider the recommendation of the board of directors of MLAC (the “MLAC Board”) in favor of approval of the Business Combination and the other proposals discussed in this proxy statement/prospectus (the “Proposals”), Public Shareholders should keep in mind that the Sponsor and its Affiliates have interests in the Proposals that are different from, or in addition to (and which may conflict with), the interests of a Public Shareholder as an MLAC Shareholder. For instance, the Sponsor will benefit from the completion of any business combination and may be incentivized to complete a business combination that is less favorable to shareholders rather than liquidating MLAC. Among other things:

• the Sponsor paid $25,000 for the 7,187,500 MLAC Class B Ordinary Shares. Of these amounts, contemporaneously with the consummation of the Business Combination, the Sponsor shall submit for cancellation 4,387,500 MLAC Class B Ordinary Shares, as a result, the Sponsor will retain 2,800,000 MLAC Class B Ordinary Shares at the Closing (the “Retained Sponsor Shares”). If the Business Combination or another MLAC initial business combination is not consummated by June 16, 2026 (or such other date as approved by the MLAC Shareholders), MLAC will cease all operations except for the purpose of winding up. In such event, the 2,800,000 Retained Sponsor Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be worthless because the holders thereof entered into an agreement waiving entitlement to participate in any redemption or liquidating distributions with respect to such shares from the monies held in the Trust Account. Neither the Sponsor nor any other person received any compensation in exchange for this agreement to waive redemption and liquidation rights. Pursuant to terms of the Insider Letter and the Sponsor Lock-Up Agreement, the Retained Sponsor Shares are subject to a lock-up whereby, subject to certain limited exceptions, the Retained Sponsor Shares are not transferable until the earlier of (A) 180 days after the completion of MLAC’s initial business combination (the “Anniversary Release”); provided that, if the VWAP of the shares of Pubco Class A Stock equals or exceeds $12.50 per share for any 20 consecutive trading days after Closing, then the Anniversary Release will be deemed to occur at 11:59 p.m. (New York City time) on such 20th consecutive trading day, or (B) subsequent to MLAC’s initial business combination, the date on which Pubco consummates a transaction which results in all of its shareholders having the right to exchange their shares for cash, securities or other properties. The Sponsor may, on or before the Closing of the Business Combination, distribute some or all of the Retained Sponsor Shares held by it and such distributed Retained Sponsor Shares may be released from lock-up restrictions in connection with applicable stock exchange listing requirements. In this regard, while the Retained Sponsor Shares are not the same as the MLAC Class A Ordinary Shares, are subject to certain restrictions that are not applicable to the MLAC Class A Ordinary Shares and may become worthless if MLAC does not complete a business combination by June 16, 2026 (or such other date as approved by the MLAC Shareholders), the aggregate value of the 2,800,000 Retained Sponsor Shares owned by the Sponsor is estimated to be approximately $29.62 million, assuming the per share value of the Retained Sponsor Shares is the same as the $10.58 closing price of the MLAC Class A Ordinary Shares on Nasdaq on May 5, 2026;

• the Sponsor has agreed that the 1,600,000 shares of Pubco Class A Stock to be issued to the Sponsor (of the total 2,800,000 Retained Sponsor Shares it will hold), will be held in escrow during the Earnout Period, subject to early release upon certain price-based Triggering Events. Additionally, any Retained Sponsor Shares that are released from escrow shall not be sold or transferred until the Anniversary Release;

• the 495,000 MLAC Private Placement Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will forfeited immediately prior to the closing pursuant to the Sponsor Support Agreement. The Sponsor purchased the MLAC Private Placement Shares at an aggregate purchase price of $4,950,000, or $10.00 per unit, in the Private Placement consummated simultaneously with the MLAC IPO. The aggregate value of the 495,000 MLAC Private Placement Shares held by the Sponsor is estimated to be approximately $5.24 million, assuming the per unit value of the MLAC Private Placement Shares is the same as the $10.58 closing price of MLAC Class A Ordinary Shares on Nasdaq on May 5, 2026;

• if the proposed Business Combination is consummated, immediately after the Closing the Sponsor and its Affiliates are anticipated to hold 2,800,000 of the outstanding shares of Pubco Common Stock, based on the assumptions set forth in the section of this proxy statement/prospectus entitled “Description of Pubco Securities,” which also incorporates relevant assumptions further described in the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information” and “Beneficial Ownership of Securities” and assuming, among other assumptions further described in aforementioned sections of this proxy statement/prospectus, no redemptions of Public Shares and no conversion of public share rights or private share rights prior to or in connection with the proposed Business Combination;

• based on the difference in the effective purchase price of $0.003 per share paid for the MLAC Class B Ordinary Shares, as compared to the purchase price of $10.00 per Unit sold in the MLAC IPO, the Sponsor and its members may earn a positive rate of return even if the share price of Pubco after the Closing falls below the price initially paid for the MLAC Units in the MLAC IPO and the unredeeming unaffiliated Public Shareholders experience a negative rate of return following the Closing of the Business Combination;

• if, prior to the Closing, the Sponsor provides working capital loans to MLAC, up to $1,500,000 of which may be convertible into MLAC Private Placement Shares at the option of the Sponsor, such loans may not be repaid if no business combination is consummated and MLAC is forced to liquidate; provided, however, that, as of the date of this proxy statement/prospectus, there are no such working capital loans outstanding;

• unless MLAC consummates an initial business combination, it is possible that MLAC’s officers, directors and the Sponsor may not receive reimbursement for out-of-pocket expenses incurred by them, to the extent that such expenses exceed the amount of available funds not deposited in the Trust Account (provided, however, that, as of the date of this proxy statement/prospectus, MLAC’s officers and directors have not incurred (nor are any of them expecting to incur) out-of-pocket expenses exceeding such funds available to MLAC for reimbursement thereof, but provided, further, that if any such expenses are incurred prior to consummation of the Business Combination, MLAC’s officers, directors and the Sponsor may not receive reimbursement therefor if the proposed Business Combination is not consummated);

• if the Trust Account is liquidated, including in the event MLAC is unable to complete an initial business combination by June 16, 2026 (or such other date as approved by the MLAC Shareholders), the Sponsor has agreed that it will be liable to MLAC, if and to the extent any claims by a third party for services rendered or products sold to MLAC (except for MLAC’s independent auditors) or a prospective target business with which MLAC has entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per share due to reductions in the value of the trust assets less taxes payable, provided, however, that such liability will not apply to any claims by a third party or prospective target business that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable), nor will it apply to any claims under MLAC’s indemnity of the underwriters of the MLAC IPO against certain liabilities, including liabilities under the Securities Act;

• the Sponsor and its Affiliates may benefit from the completion of a business combination and may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to shareholders rather than liquidate;

• MLAC agreed to pay Paul Grinberg (“Mr. Grinberg”), MLAC’s Chairman and Chief Executive Officer and Douglas Horlick, MLAC’s President and Chief Financial Officer, an aggregate of up to $20,000 per month for their services as executive officers and directors of MLAC, until the earlier to occur of the completion of MLAC’s initial business combination or its liquidation. As of December 31, 2025, MLAC has incurred and paid an expense of $240,000 of such fee;

• MLAC’s officers and directors will be eligible for continued indemnification and continued coverage under a tail policy for MLAC’s directors’ and officers’ liability insurance policy for up to a six-year period from and after the Closing for events occurring prior to the Closing, which tail policy is to be paid for by Pubco at the Closing pursuant to the Business Combination Agreement. If the Business Combination does not close, MLAC’s officers and directors may not receive this tail insurance coverage; and

• the anticipated election of Mr. Grinberg, MLAC’s Chairman and Chief Executive Officer, as a director of Pubco after the consummation of the Business Combination, who will in such role receive any cash fees, stock options or stock awards that the Pubco Board determines to pay to such directors.

Interests of Pubco’s Directors and Executive Officers in the Business Combination

In considering the recommendation of the MLAC Board to vote in favor of approval of the Proposals, unaffiliated MLAC Shareholders should keep in mind that the directors and executive officers of Pubco have interests in such Proposals that are different from or in addition to, those of unaffiliated MLAC Shareholders. In particular:

• the Company has entered into offer letters with its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer that are expected to be assigned to Pubco at the Closing.

• Pubco intends to grant equity awards under the Incentive Plan to its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer;

• the fact that Gerald Bartholomew Smith, the Company’s Chief Executive Officer, is expected to become a director and Chief Executive Officer of Pubco at Closing; and

• the Company’s Chief Executive Officer is party to an advisory agreement with Avalanche BVI that provides for payment of certain consideration if the Closing does not occur; however, in the event that the Closing does occur, Gerald Bartholomew Smith will no longer serve as an advisor to Avalanche BVI nor receive any compensation from Avalanche BVI.

For more information about the potential conflicts of interest, the nature of compensation and the potential dilutive impact of such interests held by the Sponsor and its Affiliates and Pubco’s directors and officers, see the following sections in the accompanying proxy statement/prospectus:

• “Questions and Answers About the MLAC Extraordinary General Meeting — What equity stake will current Public Shareholders (including MLAC Right Holders), the Company Unit Investors, The Sponsor and its Affiliates, the Foundation, Astral and Seller Related Parties hold in Pubco immediately after the completion of the Transactions?”

• “Risk Factors — Risks Related to the Business Combination — Since the Sponsor and its Affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders, a conflict of interest may have existed in determining whether the Business Combination with Pubco and AVAT is appropriate as MLAC’s initial business combination. Such interests include that the Sponsor will lose its entire investment in MLAC if the Business Combination is not completed or any other business combination is not completed.”

• “The Business Combination Proposal — Interests of MLAC’s Sponsor, Directors, and Officers in the Business Combination.”

• “Management of Pubco Following the Business Combination.”

• “Executive and Director Compensation.”

In addition, you should carefully consider the matters discussed under the heading entitled “Risk Factors” beginning on page 40 of the accompanying proxy statement/prospectus.

Consideration to be Received by, and Securities to be Issued to, the Sponsor and Affiliates

Set forth below is a summary of the terms and amount of the consideration received or to be received by the Sponsor and Affiliates in connection with the Transactions, the amount of securities issued or to be issued by Pubco to the Sponsor and Affiliates and the price paid or to be paid or consideration provided for such securities or any related financing transaction.

Entity	Interest in Securities/Other Consideration to be Received	Price Paid or to be Paid or Consideration Provided
Sponsor	2,800,000 MLAC Class B Ordinary Shares, of which 1,600,000 Sponsor Earnout Shares shall be held in escrow and shall vest and be released from escrow, in the amounts specified below, upon Pubco meeting the milestones specified below:	$25,000 paid to purchase the 7,187,500 MLAC Class B Ordinary Shares (of which 4,387,500 shares will be forfeited upon the Closing).
	(i)Upon the occurrence of Triggering Event I, 533,333 Sponsor Earnout Shares shall be released from the escrow account to the Sponsor;
	(ii)Upon the occurrence of Triggering Event II, 533,333 Sponsor Earnout Shares shall be released from the escrow account to the Sponsor; and
	(iii)Upon the occurrence of Triggering Event III, 533,334 Sponsor Earnout Shares shall be released from the escrow account to the Sponsor.
Sponsor	Additional MLAC Class A Ordinary Shares and/or cash	Amounts outstanding at the Closing under any MLAC Working Capital Loan will be repaid, at the lender’s option, in either cash or by the issuance of MLAC Class A Ordinary Shares at $10.00 per share.

Because the Sponsor acquired its 7,187,500 MLAC Class B Ordinary Shares at a nominal price, the Public Shareholders will incur substantial and immediate dilution upon the Closing of the Business Combination. See the sections titled “Summary of the Proxy Statement/Prospectus — Dilution,” “Risk Factors — Risks Related to the Business Combination — The value of the MLAC Class B Ordinary Shares following completion of the Business Combination is likely to be substantially higher than the nominal price paid for them, even if the trading price of shares of Pubco Class A Stock at such time is substantially less than $10.00 per share, which may create an economic incentive for the MLAC management team to pursue and consummate the Business Combination which differs from the Public Shareholders” and “Risk Factors — Risks Related to the Business Combination — Public Shareholders who do not redeem their Public Shares will experience substantial and immediate dilution upon Closing of the Business Combination as a result of the MLAC Class B Ordinary Shares held by the Sponsor, since the value of the MLAC Class B Ordinary Shares is likely to be substantially higher than the nominal price paid for them, as well as a result of the issuance of the shares of Pubco Stock in the Business Combination and as a result of the conversion of the Company Units.”

After careful consideration, the MLAC Board has unanimously approved the Business Combination Agreement and the other Proposals described in the accompanying proxy statement/prospectus and the MLAC Board has determined that it is advisable to consummate the Business Combination. The MLAC Board did not obtain a fairness opinion (or any similar report or appraisal) in connection with its determination to approve the Business Combination. However, MLAC’s management, the members of the MLAC Board and the other representatives of MLAC have experience in evaluating the operating and financial merits of cryptocurrency companies and reviewed certain financial information of Pubco and the Company and other relevant financial information selected based on the experience and the professional judgment of MLAC’s management team. Accordingly, investors will be relying solely on the judgment of the MLAC Board in valuing Pubco and the Company’s business and accordingly, investors assume the risk that the MLAC Board may not have properly valued such business. For more information, see “Risk Factors — Risks Related to the Business Combination — Neither the MLAC Board nor any committee thereof obtained a fairness opinion (or any similar report or appraisal) in determining whether or not to pursue the Business Combination. Consequently, MLAC Shareholders have no assurance from an independent source that the number of shares of Pubco Stock to be issued to Seller and MLAC Shareholders in the Business Combination is fair to MLAC — and, by extension, MLAC Shareholders — from a financial point of view.”The MLAC Board recommends that MLAC Shareholders vote “FOR” the Proposals described in the accompanying proxy statement/prospectus (including each of the sub-proposals).

This proxy statement/prospectus provides you with detailed information about the Business Combination and other matters to be considered at the Meeting. MLAC encourages you to carefully read this entire document and the documents incorporated by reference. You should also carefully consider the risk factors described in “Risk Factors” on page 40 of this proxy statement/prospectus.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROXY STATEMENT/PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

(1) The Business Combination Proposal — an ordinary resolution to approve and adopt the Business Combination Agreement (as amended, restated or otherwise modified from time to time, the “Business Combination Agreement”), dated as of October 1, 2025, by and among MLAC, Avalanche Treasury Corporation, a Delaware corporation (“Pubco”), Avalanche SPAC Merger Sub LLC, a Delaware limited liability company (“MLAC Merger Sub”), Avalanche Company Merger Sub LLC, a Delaware limited liability company (“Company Merger Sub”, and together with MLAC Merger Sub, the “Pubco Subsidiaries”), Avalanche Treasury Company LLC, a Delaware limited liability company (the “Company”), Dragonfly Digital Management, LLC, a Delaware limited liability company (“Seller”), Dragonfly Ventures L.P., a Cayman Islands exempted limited partnership (“DV”), Dragonfly Ventures II L.P., a Cayman Islands exempted limited partnership (“DVII” and together with DV, “DVs” and DVs together with Seller, the “Seller Related Parties”) and Astral Horizon L.P., a Delaware limited partnership (“Astral”), pursuant to which, and subject to the terms and conditions set forth therein, upon the consummation of the transactions contemplated thereby (the “Closing” and the date and time at which the Closing is actually held, the “Closing Date”), (a) prior to the Closing, MLAC will effect a domestication under Section 388 of the DGCL and Section 206 of the Cayman Islands Companies Act (As Revised) (the “Cayman Act”) (the “Domestication”), pursuant to which MLAC will transfer by way of continuation to and become a Delaware corporation, (b) at least two hours after the Domestication, MLAC Merger Sub will merge with and into MLAC in accordance with the applicable provisions of the General Corporation Law of the State of Delaware (the “DGCL”) and the Limited Liability Company Act of the State of Delaware (the “DLLCA”), with MLAC continuing as the surviving company and a wholly-owned subsidiary of Pubco (the “MLAC Merger”), and with MLAC shareholders receiving one share of non-voting Class A common stock, par value $0.01 per share, of Pubco (“Pubco Class A Stock”) for each Class A ordinary share, par value $0.0001 per share, of MLAC (the “MLAC Class A Ordinary Shares”) held by such shareholder, and with each holder of MLAC Rights (as defined herein) receiving one share of Pubco Class A Stock in exchange for every ten (10) MLAC Rights held by such holder and (c) Company Merger Sub will merge with and into the Company in accordance with the applicable provisions of the DLLCA, with the Company continuing as the surviving company (the “Company Merger” and, together with the MLAC Merger, the “Mergers” and, together with the other transactions contemplated by the Business Combination Agreement, including the Foundation Transaction, the Dragonfly Contribution and the Company Unit Subscription, in each case as defined herein, the “Business Combination”), and with (i) each Company Member other than Seller receiving one share of Pubco Class A Stock for each Company Unit (as defined herein) held immediately prior to the effective time of the Company Merger and (ii) Seller receiving one share of Pubco Class A Stock and one share of Pubco Class B common stock, par value $0.01 per share (“Pubco Class B Stock” and, together with the Pubco Class A Stock, the “Pubco Stock”) for each Company Unit it holds. We refer to this proposal as the “Business Combination Proposal.” The Business Combination Proposal is described in more detail in the accompanying proxy statement/prospectus under the heading “The Business Combination Proposal,” and a copy of the Business Combination Agreement is attached to the accompanying proxy statement/prospectus as Annex A.

(2) The Merger Proposal — a special resolution to approve and authorize the MLAC Merger. We refer to this proposal as the “Merger Proposal.” The Merger Proposal is described in more detail in the accompanying proxy statement/prospectus under the heading “The Merger Proposal.”

(3) The Domestication and Organizational Documents Proposals — to consider and vote, on a non-binding advisory basis, upon separate proposals as ordinary resolutions to approve the transfer of the registration of MLAC by way of continuation from the Cayman Islands to the State of Delaware and the material differences between the MLAC Memorandum and Articles and the Amended and Restated Pubco Charter and Pubco’s Amended and Restated Bylaws, substantially in the form attached to the accompanying proxy statement/prospectus as Annexes B and C (the “Proposed Organizational Documents”), specifically (collectively, the “Domestication and Organizational Documents Proposals”):

• Proposal A: the registration of MLAC will be transferred by way of continuation from the Cayman Islands to the State of Delaware.

• Proposal B: the authorized capital stock of Pubco will consist of 550,000,000 Pubco Class A Stock, 100,000,000 Pubco Class B Stock and 50,000,000 shares of preferred stock.

• Proposal C: the size and composition of the board of directors will be changed to consist of one (1) or more members, each of whom shall be a natural person.

• Proposal D: the Proposed Organizational Documents will provide for an unclassified Pubco Board; and

• Proposal E: the Proposed Organizational Documents will not include provisions related to Pubco’s status as a blank check company because Pubco is not a blank check company.

The Domestication and Organizational Documents Proposals are described in more detail in the accompanying proxy statement/prospectus under the heading “The Domestication and Organizational Documents Proposals.”

(4) The Nasdaq Proposal — an ordinary resolution to approve, for the purposes of complying with the applicable provisions of Nasdaq Rule 5635, (i) the issuance of shares of Pubco Stock in connection with the Business Combination, (ii) the issuance of shares of Pubco Stock in connection with the Company Unit Subscription, (iii) the issuance of shares of Pubco Stock in connection with the Dragonfly Contribution, (iv) the issuance of shares of Pubco Stock in connection with the Foundation Transaction, (v) the issuance of MLAC Private Placement Shares in repayment of the MLAC Working Capital Loans, and (vi) the reservation for issuance of shares of Pubco Stock that will, upon Closing, be reserved pursuant to the Incentive Plan, to the extent such issuances would require shareholder approval under Nasdaq Rule 5635. We refer to this proposal as the “Nasdaq Proposal.” The Nasdaq Proposal is described in more detail in the accompanying proxy statement/ prospectus under the heading “The Nasdaq Proposal.”

(5) The Director Election Proposal — an ordinary resolution to approve, that, two (2) directors be elected to the MLAC Board to serve until MLAC’s third annual general meeting of shareholders or their earlier death, resignation or removal (including if they are replaced at the consummation of the Business Combination). We refer to this proposal as the “Director Election Proposal,” which is described in more detail in the accompanying proxy statement/prospectus under the heading “The Director Election Proposal.”

(6) The Adjournment Proposal — an ordinary resolution to approve the adjournment of the Meeting to a later date or dates, if it is determined by MLAC that additional time is necessary or appropriate to complete the Business Combination or for any other reason. We refer to this proposal as the “Adjournment Proposal.” The Adjournment Proposal is described in more detail in the accompanying proxy statement/prospectus under the heading “The Adjournment Proposal.”

Only holders of record of MLAC Ordinary Shares at the close of business on              , 2026 (the “Record Date”) are entitled to notice of the Meeting and to vote and have their votes counted at the Meeting and any adjournments or postponements of the Meeting.

After careful consideration, the board of directors of MLAC (the “MLAC Board”) has determined that the Business Combination Proposal, the Merger Proposal, the Domestication and Organizational Documents Proposals, the Nasdaq Proposal, the Director Election Proposal and the Adjournment Proposal are in the best interests of MLAC and the MLAC Shareholders and unanimously recommends that MLAC Shareholders vote or give instruction to vote “FOR” the Business Combination Proposal, “FOR” the Merger Proposal, “FOR” each of the Domestication and Organizational Documents Proposals, “FOR” the Nasdaq Proposal, “FOR” the Director Election Proposal and “FOR” the Adjournment Proposal, if presented. When Public Shareholders consider the MLAC Board’s recommendation of the Proposals, Public Shareholders should keep in mind that the directors and officers of MLAC and Pubco have interests in the Business Combination that may conflict with the interests of a Public Shareholder as an MLAC Shareholder. For a more complete description of these interests, see the sections entitled “Summary of the Proxy Statement/ Prospectus — Interests of the Sponsor and its Affiliates in the Business Combination” and “The Business Combination Proposal — Interests of Pubco’s Directors and Executive Officers in the Business Combination.”

The MLAC Board has already approved the Business Combination. The MLAC Board did not obtain a fairness opinion (or any similar report or appraisal) in connection with its determination to approve the Business Combination. However, MLAC’s management, the members of the MLAC Board and the other representatives of MLAC have experience in evaluating the operating and financial merits of cryptocurrency companies and reviewed certain financial information of Pubco and the Company and other relevant financial information selected based on the experience and the professional judgment of MLAC’s management team. Accordingly, investors will be relying solely on the judgment of the MLAC Board in valuing Pubco and the Company’s business and accordingly, investors assume the risk that the MLAC Board may not have properly valued such business. For more information, see the risk factor entitled “Risk Factors — Risks Related to the Business Combination — Neither the MLAC Board nor any committee thereof obtained a fairness opinion (or any similar report or appraisal) in determining whether or not to pursue the Business Combination. Consequently, MLAC Shareholders have no assurance from an independent source that the number of shares of Pubco Stock to be issued to Sellers and MLAC Shareholders in the Business Combination is fair to MLAC — and, by extension, MLAC Shareholders — from a financial point of view.”

To pass, each of the Business Combination Proposal, the Nasdaq Proposal, the Director Election Proposal and the Adjournment Proposal requires an ordinary resolution of MLAC Shareholders, which requires the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). To pass, the Merger Proposal requires a special resolution of MLAC Shareholders, which requires the affirmative vote of at least two-thirds of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). MLAC Shareholders are also being asked to approve by way of ordinary resolutions, on a non-binding advisory basis, each of the Domestication and Organizational Documents Proposals. Although the MLAC Board is asking MLAC Shareholders to approve each of the Domestication and Organizational Documents Proposals on the non-binding advisory basis, regardless of the outcome of the non-binding advisory vote on each of the Domestication and Organizational Documents Proposals, the Amended and Restated Pubco Charter and Pubco’s Amended and Restated Bylaws will take effect upon the Closing if the Business Combination Proposal and the Merger Proposal are approved.

Under the Business Combination Agreement, the approval by MLAC Shareholders of the Business Combination Proposal and the Merger Proposal are conditions to the consummation of the Business Combination. If the Business Combination Proposal and the Merger Proposal are not approved by MLAC Shareholders, the Business Combination will not be consummated. The Merger Proposal is conditioned upon the approval of the Business Combination Proposal. The Domestication and Organizational Documents Proposals and the Nasdaq Proposal and are conditioned upon the approval of the Business Combination Proposal and the Merger Proposal (together, the “MLAC Shareholder Approval Matters”). The Director Election Proposal and the Adjournment Proposal are not conditioned on the approval of any other Proposal.

The Sponsor currently holds 7,187,500 Class B ordinary shares of MLAC, par value $0.0001 per share (the “MLAC Class B Ordinary Shares” and, together with the MLAC Class A Ordinary Shares, the “MLAC Ordinary Shares”), and 495,000 MLAC Private Placement Shares. The Sponsor has agreed to vote its 7,682,500 MLAC Ordinary Shares, representing 24.8% of the issued and outstanding MLAC Ordinary Shares, in favor of each of the Proposals. As a result, with respect to each Proposal that require approval of MLAC Shareholders by an ordinary resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 7,813,751, or 34.0%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting) to be voted in favor of such Proposals in order to have such Proposals approved.

Upon the completion of the Transactions, and assuming, among other things, that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination, that no shares of Pubco Class A Stock are issued pursuant to the Pubco 2026 Omnibus Incentive Plan to be adopted prior to Closing, as amended from time to time (the “Incentive Plan”) and no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements, (i) Public Shareholders (including MLAC Right Holders), (ii) the Company Unit Investors, (iii) the Sponsor and its Affiliates, (iv) the Foundation, (v) Astral and (vi) Seller Related Parties will own approximately 41.8%, 35.7%, 4.6%, 5.0%, 3.3% and 9.6% of the issued and outstanding shares of Pubco Class A Stock, respectively and approximately 0%, 0%, 0%, 0%, 0% and 100% of the issued and outstanding shares of Pubco Class B Stock, respectively.

Assuming that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination, the aggregate value of consideration the Public Shareholders (including MLAC Right Holders) will receive is $253,000,000 consisting of 25,300,000 shares of Pubco Stock; the aggregate value of consideration the MLAC Right Holders will receive is $23,000,000 consisting of 2,300,000 shares of Pubco Stock; the aggregate value of consideration the Public Shareholders (exclusive of the MLAC Right Holders) will receive is $230,000,000 consisting of 23,000,000 shares of Pubco Stock; and the aggregate value of consideration Astral will receive is $40,000,000 consisting of 4,000,000 shares of Pubco Stock.

Each holder of shares of Pubco Class A Stock will have no voting rights, except (i) as required by the General Corporation Law of the State of Delaware (the “DGCL”) or (ii) on any matter that adversely affects them relative to holders of any other class of stock of Pubco, until all shares of Pubco Class B Stock are canceled. Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights. Each holder of shares of Pubco Class B Stock will be entitled to one vote for each share of Pubco Class B Stock held of record by such holder on all matters on which stockholders are generally entitled to vote. Therefore under the above assumptions, (i) Public Shareholders (including MLAC Right Holders), (ii) the Company Unit Investors, (iii) the Sponsor and its Affiliates, (iv) the Foundation, (v) Astral and (vi) Seller Related Parties will have approximately 0%, 0%, 0%, 0%, 0% and 100% of the voting power of Pubco, respectively, following the Business Combination.

The price per share of Pubco Class A Stock is $10.00 per share for (i) Public Shareholders (including MLAC Right Holders), (ii) the Company Unit Investors, (iii) the Sponsor and its Affiliates, (iv) the Foundation, (v) Astral and (vi) Seller Related Parties. The value of the consideration that the Public Shareholders are each receiving in connection with the Business Combination is thus $10.00 per share.

Pursuant to the Business Combination Agreement, Seller will receive an equal number of shares of both Pubco Class A and Pubco Class B Stock equal to the dollar value of 1,960,040 AVAX pursuant to the Contribution Agreement, using the Signing Price, divided by $10.00. Seller and Seller Related Parties will be issued 5,805,638 shares of Pubco Class A Stock and 5,805,638 shares of Pubco Class B Stock at Closing, together valued at $10.00 per share of Class A Stock and Class B Stock combined, for a total value of $58,056,384.

On the basis of the foregoing and with the price per share of Pubco Class A Stock assumed at $10.00, the aggregate value of the consideration in Pubco Stock offered pursuant to this registration statement is $554,686,704, comprising $230,000,000 consisting of 23,000,000 shares of Pubco Stock to the Public Shareholders (exclusive of the MLAC Right Holders); $23,000,000 consisting of 2,300,000 shares of Pubco Stock to the MLAC Right Holders; $28,000,000 consisting of 2,800,000 shares of Pubco Stock to the Sponsor and its Affiliates; $58,056,384 consisting of 5,805,638 shares of Pubco Class A Stock and 5,805,638 shares of Pubco Class B Stock to the Seller Related Parties and $215,630,320 consisting of 21,563,032 shares of Pubco Stock to the Company Unit Investors.

Pursuant to the amended and restated memorandum and articles of association of MLAC as of the date hereof (the “MLAC Memorandum and Articles”), MLAC is providing the holders (the “Public Shareholders”) of MLAC Class A Ordinary Shares issued in the initial public offering of MLAC (the “MLAC IPO” and such shares, the “Public Shares”) with the opportunity to redeem, upon the Closing, Public Shares then held by them for cash equal to their pro rata share of the aggregate amount on deposit (as of two (2) business days prior to the Closing) in MLAC’s trust account (the “Trust Account”) that holds the proceeds (including interest but less taxes payable) of the MLAC IPO. For illustrative purposes, based on funds in the Trust Account of approximately $241.2 million as of December 31, 2025 and $244.2 million as of May 4, 2026, the estimated per share redemption prices would have been approximately $10.49 per share and $10.62 per share, respectively (including interest earned on the funds held in the Trust Account but less taxes payable). Public Shareholders are not required to affirmatively vote for or against the Business Combination in order to redeem their Public Shares for cash. This means that MLAC Shareholders who hold Public Shares on or before          , 2026 (two (2) business days before the Meeting) will be eligible to elect to have their Public Shares redeemed for cash in connection with the Meeting, whether or not they are holders as of the Record Date, and whether or not such Public Shares are voted at the Meeting.

The Sponsor and its Affiliates have agreed to waive their redemption rights with respect to any MLAC Ordinary Shares they may hold in connection with the consummation of the Business Combination, and such shares will be excluded from the pro rata calculation used to determine the per-share redemption price.

All MLAC Shareholders are cordially invited to attend the Meeting. Your vote is important regardless of the number of shares you own. Whether you plan to attend the Meeting or not, to ensure your representation at the Meeting, you are urged to complete, sign, date and return the enclosed proxy card as soon as possible. If you are a holder of record of MLAC Ordinary Shares, you may also cast your vote at the Meeting via Internet or in person. If your MLAC Ordinary Shares are held in an account at a brokerage firm or bank, you must instruct your broker or bank on how to vote your shares or, if you wish to attend the Meeting and vote yourself, obtain a proxy from your broker or bank. If you do not vote or do not instruct your broker or bank how to vote, it will have no effect on any of the Proposals.

Your attention is directed to the proxy statement accompanying this notice (including the annexes thereto) for a more complete description of the proposed Business Combination and related transactions and each of the Proposals. We encourage you to read this proxy statement carefully. If you have any questions or need assistance voting your shares, you may call Sodali & Co, MLAC’s proxy solicitor, at (203) 658-9400 (banks and brokers) or email at MLAC.info@investor.sodali.com.

QUESTIONS AND ANSWERS ABOUT THE PROPOSALS

The questions and answers below highlight only selected information from this proxy statement/ prospectus and only briefly address some commonly asked questions about the Meeting and the Proposals. The following questions and answers do not include all the information that is important to MLAC Shareholders. MLAC Shareholders are urged to carefully read this entire proxy statement/prospectus, including the annexes and the other documents referred to herein, to fully understand the proposed Business Combination and the voting procedures for the Meeting.

Q:Why am I receiving this proxy statement/prospectus?

A: On October 1, 2025, MLAC, Pubco, MLAC Merger Sub, Company Merger Sub, the Company and Seller entered into the Business Combination Agreement, pursuant to which they agreed to effect the Business Combination on the terms set forth therein and as described in this proxy statement/prospectus. MLAC Shareholders are being asked to vote to approve the Business Combination Agreement and the Business Combination. The Business Combination Agreement provides that, among other things:

• prior to the Closing, MLAC will effect the Domestication, pursuant to which MLAC will transfer by way of continuation to and become a Delaware corporation;

• at least two (2) hours after the Domestication, MLAC Merger Sub will merge with and into MLAC, with MLAC continuing as the surviving company and a wholly-owned subsidiary of Pubco and with MLAC Shareholders receiving one (1) share of non-voting Pubco Class A Stock for each MLAC Class A Ordinary Shares held by such shareholder, and with each holder of MLAC Rights receiving one (1) share of Pubco Class A Stock in exchange for every ten (10) MLAC Rights held by such holder. No fractional shares of Pubco Class A Stock will be issued to such holders upon conversion and exchange of the MLAC Rights. Fractional shares will be rounded down to the nearest whole share in accordance with the applicable provisions of Cayman Islands law. As a result, you must hold MLAC Rights in multiples of ten in order to receive shares for all of your MLAC Rights upon the Closing;

• Company Merger Sub will merge with and into the Company, with the Company continuing as the surviving company, and with (i) each Company Member other than Seller Related Parties receiving one (1) share of Pubco Class A Stock for each Company Unit held immediately prior to the effective time of the Company Merger and (ii) each Seller Related Party receiving one (1) share of Pubco Class A Stock, par value $0.01 per share (“Pubco Class A Stock”) and one (1) share of Pubco Class B common stock, par value $0.01 per share (“Pubco Class B Stock”) for each Company Unit it holds; and

• Astral Horizon, L.P., a Delaware limited partnership (“Astral”) shall be entitled to receive 4,000,000 Pubco Class A Stock as Additional Merger Consideration Shares, out of which (i) 2,000,000 shares of Pubco Class A Stock will be deposited, upon the Closing, into the Astral Escrow Account, and will be released in tranches, as provided for in the Business Combination Agreement and the Astral Escrow Agreement, and (ii) 2,000,000 shares of Pubco Class A Stock will be issued and delivered on the thirtieth (30^th) calendar day following the Closing Date.

Concurrently with the signing of the Business Combination Agreement, on October 1, 2025, Pubco, Company and MLAC entered into the Company Unit Subscription Agreements with the Company Unit Investors, pursuant to which the Company Unit Investors agreed to purchase, payable in cash, USD Coin (“USDC”) or AVAX (or a combination of cash, USDC and/or AVAX), and the Company agreed to issue and sell, approximately $216 million worth of Company Class A units (the “Company Units”) at a price of $10.00 per Company Unit, in a private placement (the “Company Unit Subscription”), upon the terms and subject to the conditions set forth therein. Company Unit Investors received a number of Company Units equal to, (a) if the Company Unit Investor elected to purchase Company Units by contributing AVAX, the stated AVAX amount (“Stated AVAX Amount”) multiplied by the applicable signing AVAX price (“Applicable Signing AVAX Price”), or, (b) if the Company Unit Investor elected to purchase the Company Units by contributing cash or USDC, the stated dollar amount (“Stated Dollar Amount”) or the stated USDC amount (“Stated USDC Amount”) (as applicable), in each case divided by $10.00 (the “Per Unit Price”).

xxviii

Each Company Unit Investor was required to fund its respective cash or USDC within three business days following the execution date of the Company Unit Subscription Agreement, and to fund its respective AVAX as soon as reasonably possible after the execution date of the Company Unit Subscription Agreement, in any case on or prior to November 7, 2025, in accordance with the terms of the Company Unit Subscription Agreements. At the Company Merger Effective Time, each Company Unit held by Company Unit Investors will be converted automatically into one share of Pubco Class A Stock. The Company Unit Investors, in accordance with the provisions of the Company Unit Subscription Agreements, agreed to purchase, payable in cash, USDC or AVAX, and the Company agreed to issue and sell, approximately $216 million worth of Company Units, consisting of a contractual value of approximately $96.4 million invested in cash, $22.3 million invested in USDC and $96.8 million invested in AVAX. The fair value of the proceeds received was approximately $96.5 million in cash, $22.3 million in USDC and $59.4 million in AVAX, representing the fair value of the AVAX received on the date the shares were transferred, and 192,293.45 AVAX to be received valued at $2 million as of January 31, 2026.

As of December 31, 2025, AVAT had received 3,340,696.22 AVAX tokens pursuant to the Company Unit Subscription and had purchased a total of 2,195,587 AVAX tokens using the cash and USDC proceeds of the Company Unit Subscription. As of December 31, 2025, the fair value of the 5,536,283.22 AVAX tokens received pursuant to the Company Unit Subscription and purchased using the cash and USDC proceeds of the Company Unit Subscription was $12.30 per token, or approximately $68,096,283.60. As of May 5, 2026, the average trading price of AVAX for such day was $9.34 per token; on the basis of the foregoing price, the value of the 5,536,283.22 AVAX tokens received pursuant to the Company Unit Subscription and purchased using the cash and USDC proceeds of the Company Unit Subscription as of December 31, 2025 would be approximately $51.7 million.

Also concurrently with the signing of the Business Combination Agreement, on October 1, 2025, the Seller, directly and/or indirectly through Dragonfly Ventures L.P. and Dragonfly Ventures II, L.P. (the “Funds” and together with other Seller controlled vehicles, the “Seller Related Parties”), contributed 1,960,040 AVAX, all upon the terms and subject to the conditions set forth in the Contribution Agreement, for a contractual value of approximately $58 million worth of Company Units at the Per Unit Price (the “Dragonfly Contribution”), and for a total combined contractual value, between the Company Unit Subscription and the Dragonfly Contribution, of approximately $274 million worth of Company Units. As of December 31, 2025, the fair value of the 1,960,040 AVAX tokens contributed pursuant to the Dragonfly Contribution was $12.30 per token, or approximately $24.1 million. As of May 5, 2026, the average trading price of AVAX for such day was $9.34 per token; on the basis of the foregoing price, the value of the 1,960,040 AVAX tokens contributed pursuant to the Dragonfly Contribution would be approximately $18.3 million.

xxxi

Q: Why is MLAC providing MLAC Shareholders with the opportunity to vote on the Business Combination?

A: Under the MLAC Memorandum and Articles, MLAC must provide all Public Shareholders with the opportunity to have their Public Shares redeemed upon the consummation of MLAC’s initial business combination either in conjunction with a tender offer or in conjunction with a shareholder vote. For business reasons and pursuant to Cayman Islands law requirements, MLAC has elected to structure the Business Combination in such a way as to provide Public Shareholders with the opportunity to have their Public Shares redeemed in connection with a shareholder vote rather than a tender offer. Therefore, MLAC is seeking to obtain the approval of the MLAC Shareholders of the Business Combination Proposal, among the other Proposals, in order to allow the Public Shareholders to effectuate redemptions of their Public Shares in connection with the consummation of the Business Combination.

Q: Are there any arrangements to help ensure that there will be sufficient funds to consummate the Business Combination?

A: Yes. On October 1, 2025, Pubco, the Company and MLAC entered into the Company Unit Subscription Agreements with the Company Unit Investors, pursuant to which the Company Unit Investors agreed to purchase, payable in cash, USDC or AVAX, and the Company agreed to issue and sell, approximately $216 million worth of Company Units at the Per Unit Price, consisting of a contractual value of approximately $96.4 million invested in cash, $22.3 million invested in USDC and $96.8 million invested in AVAX. The fair value of the proceeds received was approximately $96.5 million in cash, $22.3 million in USDC and $59.4 million in AVAX, representing the fair value of the AVAX received on the date the shares were transferred, and 192,293.45 AVAX to be received valued at $2 million as of January 31, 2026. Company Unit Investors received a number of Company Units equal to (a) if the Company Unit Investor elected to purchase Company Units by contributing AVAX, the Stated AVAX Amount multiplied by the Applicable Signing AVAX Price, or (b) if the Company Unit Investor elected to purchase the Company Units by contributing cash or USDC, the Stated Dollar Amount or the Stated USDC Amount (as applicable), in each case divided by the Per Unit Price. Each Company Unit Investor was required to fund its respective cash or USDC within three business days following the execution date of the Company Unit Subscription Agreement, and to fund its respective AVAX as soon as reasonably possible after the execution date of the Company Unit Subscription Agreement, in any case on or prior to November 7, 2025, in accordance with the terms of the Company Unit Subscription Agreements. At the Company Merger Effective Time, each Company Unit held by Company Unit Investors will be converted automatically into one share of Pubco Class A Stock. The Company Unit Investors, in accordance with the provisions of the Company Unit Subscription Agreements, agreed to purchase, payable in cash, USDC or AVAX, and the Company agreed to issue and sell, approximately $216 million worth of Company Units.

The proceeds from the Trust Account (net of any amounts used to fund the redemptions of Public Shares) will be used to pay any transaction expenses of the parties, including certain of the MLAC loans, administrative expenses of the parties and any remainder will be used for general corporate purposes, including, but not limited to, working capital for operations and to purchase additional AVAX. The proceeds from the Company Unit Subscription were used to purchase AVAX, and, net of the amounts used to purchase the AVAX or to the extent any such AVAX is liquidated, may to the extent necessary be used to fund any transaction or administrative expenses of the parties or for general corporate purposes at the discretion of management pursuant to the First Amended and Restated LLC Agreement. The amount of AVAX held in comparison to cash-on-hand fluctuates at any given time according to market conditions and the business judgment of the Company’s management regarding desired asset distribution, liquidity and working capital requirements. The Company maintains enough working capital in cash to pay for ongoing transaction expenses, and also generates yield from staked AVAX that can be liquidated as needed to further fund transaction or other operating expenses. As of December 31, 2025, the Company had generated $1,434,669 in net staking rewards from 118,735 AVAX received. Should the Company require additional liquidity at Closing to pay transaction expenses, management maintains the flexibility to liquidate AVAX as needed. As of December 31, 2025 and May 4, 2026, approximately 36.5% and 19.4%, respectively, of the AVAX holdings of AVAT were unlocked and unstaked, available to be liquidated as needed to fund transaction or other operating expenses. In addition, MLAC and Pubco may seek to arrange for additional third-party financing which may be in the form of debt (including convertible notes) or equity, the proceeds of which would be used for a variety of purposes.

Q: How many votes do I have at the Meeting?

A: MLAC Shareholders are entitled to one vote at the Meeting for each MLAC Ordinary Share held of record as of          , 2026, the Record Date for the Meeting. As of the close of business on the Record Date, there were 30,992,500 MLAC Ordinary Shares issued and outstanding.

Q: What vote is required to approve the proposals presented at the Meeting?

A: To pass, each of the Business Combination Proposal, the Nasdaq Proposal, the Director Election Proposal and the Adjournment Proposal requires an ordinary resolution of MLAC Shareholders, which requires the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). To pass, the Merger Proposal requires a special resolution of MLAC Shareholders, which requires the affirmative vote of at least two-thirds of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). MLAC Shareholders are also being asked to approve by way of ordinary resolutions, on a non-binding advisory basis, each of the Domestication and Organizational Documents Proposals. Although the MLAC Board is asking MLAC Shareholders to approve each of the Domestication and Organizational Documents Proposals on the non-binding advisory basis, regardless of the outcome of the non-binding advisory vote on each of the Domestication and Organizational Documents Proposals, the Amended and Restated Pubco Charter and Pubco’s Amended and Restated Bylaws will take effect upon the Closing if the Business Combination Proposal and the Merger Proposal are approved.

Assuming a quorum is established, an MLAC Shareholder’s failure to vote by proxy or to vote at the Meeting will have no effect on the Proposals. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast and will have no effect on any of the Proposals. The Sponsor currently holds 7,187,500 MLAC Class B Ordinary Shares and 495,000 MLAC Class A Ordinary Shares underlying its 495,000 MLAC Private Placement Shares, representing 24.8% of the issued and outstanding MLAC Ordinary Shares. The Sponsor has agreed to vote its 7,682,500 MLAC Ordinary Shares in favor of each of the Proposals. As a result, with respect to each Proposal that requires approval of MLAC Shareholders by an ordinary resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 7,813,751, or 34.0%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposals in order to have such Proposals approved. With respect to the Merger Proposal which requires approval of MLAC Shareholders by a special resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 12,979,167, or 56.4%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposal in order to have such Proposal approved.

Q: Are the Proposals conditioned on one another?

A: Under the Business Combination Agreement, the approval by MLAC Shareholders of the Business Combination Proposal and the Merger Proposal are conditions to the consummation of the Business Combination. If any of those Proposals are not approved by MLAC Shareholders, the Business Combination will not be consummated. The Merger Proposal is conditioned upon the approval of the Business Combination Proposal. The Domestication and Organizational Documents Proposal and the Nasdaq Proposal are conditioned upon the approval of the MLAC Shareholder Approval Matters. The Director Election Proposal and the Adjournment Proposal are not conditioned on the approval of any other Proposal.

Q: What constitutes a quorum at the Meeting?

A: A quorum of MLAC Shareholders is necessary to hold a valid meeting. A quorum for the Meeting consists of the holders of one-third of the then issued and outstanding MLAC Ordinary Shares (whether in person (including via the virtual meeting platform) or by proxy). As of the Record Date, MLAC Shareholders holding 10,330,834 MLAC Ordinary Shares would be required to achieve a quorum at the Meeting without the MLAC Ordinary Shares held by the Sponsor. In addition to the MLAC Ordinary Shares held by the Sponsor, which represent approximately 24.8% of the issued and outstanding MLAC Ordinary Shares and which will

xxxiii

count towards this quorum, MLAC will need MLAC Shareholders holding 2,648,334, or 11.5%, of the 23,000,000 Public Shares represented in person (including via the virtual meeting platform) or by proxy at the Meeting to have a valid quorum.

Q: How will the Sponsor and its Affiliates vote?

A: The Sponsor has agreed to vote its 7,682,500 MLAC Ordinary Shares, representing 24.8% of the issued and outstanding MLAC Ordinary Shares, in favor of each of the Proposals. Pursuant to the Insider Letter, each of MLAC’s executive officers and directors have agreed to vote any MLAC Ordinary Shares held by them in favor of the initial business combination, including the Business Combination.

As a result, with respect to each Proposal that requires approval of MLAC Shareholders by an ordinary resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 7,813,751, or 34.0%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposals in order to have such Proposals approved. With respect to the Merger Proposal which requires approval of MLAC Shareholders by a special resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 12,979,167, or 56.4%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposal in order to have such Proposal approved.

Q: What interests do the Sponsor, MLAC’s directors and executive officers and their affiliates have in the Business Combination?

A: In considering the recommendation of the MLAC Board to vote in favor of the Business Combination, Public Shareholders should be aware that, aside from their interests as shareholders, the Sponsor and its Affiliates have interests in the Business Combination that are different from, or in addition to, those of MLAC’s other shareholders generally, including the aggregate amount at risk to the Sponsor of $4,975,000, which is the amount that the Sponsor paid for its Sponsor Shares and MLAC Private Placement Shares. MLAC’s directors were aware of and considered these interests, among other matters, in evaluating the Business Combination, and in recommending to the Public Shareholders that they approve the Business Combination. Further, the interests of the Sponsor and current officers or directors of MLAC may be different from or in addition to (and which may conflict with) your interests and they may be incentivized to complete a less favorable business combination rather than liquidating MLAC. Public Shareholders should take these interests into account in deciding whether to approve the Business Combination. These interests include, among other things, the fact that:

• the Sponsor paid $25,000 for the 7,187,500 MLAC Class B Ordinary Shares. Of these amounts, contemporaneously with the consummation of the Business Combination, the Sponsor shall submit for cancellation 4,387,500 MLAC Class B Ordinary Shares, as a result, the Sponsor will retain 2,800,000 MLAC Class B Ordinary Shares at the Closing (the “Retained Sponsor Shares”). If the Business Combination or another MLAC initial business combination is not consummated by June 16, 2026 (or such other date as approved by the MLAC Shareholders), MLAC will cease all operations except for the purpose of winding up. In such event, the 2,800,000 Retained Sponsor Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be worthless because the holders thereof entered into an agreement waiving entitlement to participate in any redemption or liquidating distributions with respect to such shares. Neither the Sponsor nor any other person received any compensation in exchange for this agreement to waive redemption and liquidation rights. Pursuant to terms of the Insider Letter and the Sponsor Lock-Up Agreement, the Retained Sponsor Shares are subject to a lock-up whereby, subject to certain limited exceptions, the Retained Sponsor Shares are not transferable until the earlier of (A) 180 days after the completion of MLAC’s initial business combination; provided that, if the VWAP of the shares of Pubco Class A Stock equals or exceeds $12.50 per share for any 20 consecutive trading days after Closing, then the Anniversary Release will be deemed to occur at 11:59 p.m. (New York City time) on such 20th consecutive trading day, or (B) subsequent to MLAC’s initial business combination, the date on which Pubco consummates a transaction which results in all of its shareholders having the right to exchange their shares for cash, securities or other properties. (The Sponsor may, on or before the Closing of the Business Combination, distribute some or all of the Retained Sponsor Shares held by it and such distributed Retained Sponsor Shares may be released from lock-up restrictions in connection with applicable stock exchange listing requirements.) In this regard, while the Retained Sponsor Shares are not the same as the MLAC Class A Ordinary Shares, are subject to certain restrictions that are not applicable to the MLAC Class A Ordinary Shares, and may become worthless if MLAC does not complete a business combination by June 16, 2026 (or such other date as approved by the MLAC shareholders), the aggregate value of

xxxiv

the 2,800,000 Retained Sponsor Shares owned by the Sponsor is estimated to be approximately $29.62 million, assuming the per share value of the Retained Sponsor Shares is the same as the $10.58 closing price of the MLAC Class A Ordinary Shares on Nasdaq on May 5, 2026;

• the Sponsor has agreed that the 1,600,000 shares of Pubco Class A Stock to be issued to the Sponsor (of the total 2,800,000 Retained Sponsor Shares it will hold), will be held in escrow during the Earnout Period, subject to early release upon certain price-based Triggering Events. Additionally, any Retained Sponsor Shares that are released from escrow shall not be sold or transferred until the Anniversary Release;

• the 495,000 MLAC Private Placement Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be forfeited immediately prior to the closing pursuant to the Sponsor Support Agreement. The Sponsor purchased the MLAC Private Placement Shares at an aggregate purchase price of $4,950,000, or $10.00 per unit, in the Private Placement consummated simultaneously with the MLAC IPO. The aggregate value of the 495,000 MLAC Private Placement Shares held by the Sponsor is estimated to be approximately $5.24 million, assuming the per unit value of the MLAC Private Placement Shares is the same as the $10.58 closing price of the MLAC Class Ordinary Shares on Nasdaq on May 5, 2026;

• if the proposed Business Combination is consummated, immediately after the Closing the Sponsor and its Affiliates are anticipated to hold 4.9% of the outstanding shares of Pubco Common Stock, based on the assumptions set forth in the section of this proxy statement/prospectus entitled “Share Calculations and Ownership Percentages”, which also incorporate relevant assumptions further described in the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information” and “Beneficial Ownership of Securities” and assuming, among other assumptions further described in aforementioned sections of this proxy statement/ prospectus, no redemptions of Public Shares and no conversion of public share rights or private share rights prior to or in connection with the proposed Business Combination;

• based on the difference in the effective purchase price of $0.003 per share paid for the MLAC Class B Ordinary Shares, as compared to the purchase price of $10.00 per Unit sold in the MLAC IPO, the Sponsor and its members may earn a positive rate of return even if the share price of Pubco after the Closing falls below the price initially paid for the MLAC Units in the MLAC IPO and the unredeeming unaffiliated Public Shareholders experience a negative rate of return following the Closing of the Business Combination;

• if, prior to the Closing, the Sponsor provides working capital loans to MLAC, up to $1,500,000 of which may be convertible into MLAC Private Placement Shares at the option of the Sponsor, such loans may not be repaid if no business combination is consummated and MLAC is forced to liquidate; provided, however, that, as of the date of this proxy statement/prospectus, there are no such working capital loans outstanding;

• unless MLAC consummates an initial business combination, it is possible that MLAC’s officers, directors and the Sponsor may not receive reimbursement for out-of-pocket expenses incurred by them, to the extent that such expenses exceed the amount of available funds not deposited in the Trust Account (provided, however, that, as of the date of this proxy statement/prospectus, MLAC’s officers and directors have not incurred (nor are any of them expecting to incur) out-of-pocket expenses exceeding such funds available to MLAC for reimbursement thereof, but provided, further, that if any such expenses are incurred prior to consummation of the Business Combination, MLAC’s officers, directors and the Sponsor may not receive reimbursement therefor if the proposed Business Combination is not consummated);

• if the Trust Account is liquidated, including in the event MLAC is unable to complete an initial business combination by June 16, 2026 (or such other date as approved by the MLAC shareholders), the Sponsor has agreed that it will be liable to MLAC, if and to the extent any claims by a third party for services rendered or products sold to MLAC (except for MLAC’s independent auditors) or a prospective target business with which MLAC has entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per share due to reductions in the value of the trust assets less taxes payable, provided, however, that such liability will not apply to any claims by a third party or prospective target business that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is

xxxv

enforceable), nor will it apply to any claims under MLAC’s indemnity of the underwriters of the MLAC IPO against certain liabilities, including liabilities under the Securities Act;

• the Sponsor and its Affiliates may benefit from the completion of a business combination and may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to shareholders rather than liquidate;

• MLAC agreed to pay Paul Grinberg (“Mr. Grinberg”), MLAC’s Chairman and Chief Executive Officer and Douglas Horlick, MLAC’s President and Chief Financial Officer, an aggregate of up to $20,000 per month for their services as executive officers and directors of MLAC, until the earlier to occur of the completion of MLAC’s initial business combination or its liquidation. As of December 31, 2025, MLAC has incurred and paid an expense of $240,000 of such fee; and

• MLAC’s officers and directors will be eligible for continued indemnification and continued coverage under a tail policy for MLAC’s directors’ and officers’ liability insurance policy for up to a six-year period from and after the Closing for events occurring prior to the Closing, which tail policy is to be paid for by Pubco at the Closing pursuant to the Business Combination Agreement. If the Business Combination does not close, MLAC’s officers and directors may not receive this tail insurance coverage.

• the anticipated election of Mr. Grinberg, MLAC’s Chairman and Chief Executive Officer, as director of Pubco after the consummation of the Business Combination. As such, in the future, such directors will receive any cash fees, stock options or stock awards that the Pubco Board determines to pay to such directors.

• in addition to the interests of the Sponsor and its Affiliates in the Business Combination, MLAC shareholders should be aware that MLAC’s underwriter for its IPO, BTIG, may also have financial interests that are different from, or in addition to, the interests of MLAC shareholders, including the fact that:

• pursuant to an amendment to the underwriting agreement in connection with MLAC’s IPO, BTIG may receive a deferred fee equal to $1,000,000, and such fees are payable at the Closing of the Business Combination only if MLAC completes the Business Combination; and pursuant to the Sponsor Support Agreement, BTIG will forfeit its 310,000 MLAC Private Placement Shares; and

• pursuant to the BTIG Financial Advisory Services Agreement, BTIG may receive reimbursement of all reasonable out-of-pocket expense as financial advisor to MLAC in connection with the Business Combination, (provided that, if the expense exceeding $100,000, BTIG shall submit to MLAC for its prior written approval), such reimbursement are payable at the Closing of the Business Combination only if MLAC completes an initial business combination;

These interests may have influenced the MLAC Board in making their recommendation that you vote in favor of the approval of the Business Combination. The members of the MLAC Board were aware of and considered these interests, among other matters, when they approved the Business Combination and recommended that MLAC shareholders approve the proposals required to effect the Business Combination. The MLAC Board determined that the overall benefits expected to be received by MLAC and its shareholders in the Business Combination outweigh any potential risk created by the conflicts stemming from these interests. In addition, the MLAC Board determined that potentially disparate interests would be mitigated because (i) most of these disparate interests would exist with respect to a business combination by MLAC with any other target business or businesses, (ii) these interests could be adequately disclosed to shareholders in this proxy statement/prospectus, and that shareholders could take them into consideration when deciding whether to vote in favor of the proposals set forth herein and (iii) the Sponsor will hold equity interests in Pubco with value that, after the Closing, will be based on the future performance of Pubco’s stock.

For more information, see “Certain Relationships and Related Party Transactions” and see the risk factor entitled “Risk Factors — Risks Related to the Business Combination — Since the Sponsor and its Affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders, a conflict of interest may have existed in determining whether the Business Combination with Pubco and the Company is appropriate as MLAC’s initial business combination. Such interests include that the Sponsor will lose its entire investment in MLAC if the Business Combination is not completed or any other business combination is not completed.”

The MLAC Board reviewed and considered the potential conflicting interests described above with respect to the Sponsor and Affiliates and, after taking into account the factors they deemed applicable (including the potential conflicting interests), unanimously approved the Business Combination Agreement and the transactions contemplated therein.

Q: What interests do Pubco’s directors and executive officers have in the Business Combination?

A: In considering the recommendation of the MLAC Board to vote in favor of approval of the Proposals, unaffiliated MLAC Shareholders should keep in mind that the directors and executive officers of Pubco have interests in such Proposals that are different from or in addition to, those of unaffiliated MLAC Shareholders. In particular:

• the Company has entered into offer letters with its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer that are expected to be assigned to Pubco at the Closing;

• Pubco intends to grant equity awards under the Incentive Plan to its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer;

• the fact that Gerald Bartholomew Smith, the Company’s Chief Executive Officer, is expected to become a director and Chief Executive Officer of Pubco at Closing; and

• the Company’s Chief Executive Officer is party to an advisory agreement with Avalanche BVI that provides for payment of certain consideration if the Closing does not occur; however, in the event that the Closing does occur, Gerald Bartholomew Smith will no longer serve as an advisor to Avalanche BVI nor receive any compensation from Avalanche BVI.

Q: When will the Sponsor and Seller be entitled to transfer their shares of Pubco Class A Stock?

A: Each of the Sponsor and Seller has agreed to restrictions on its ability to transfer, assign or sell their shares of Pubco Class A Stock, as summarized in the table below. Such transfer restrictions will apply until the applicable expiration date, unless earlier waived by the contracting parties.

Subject Securities	Persons Subject to Restrictions	Expiration Date	Exceptions to Transfer Restrictions
MLAC Founder Shares (and the shares of Pubco Class A Stock received by the Sponsor in exchange therefore in the MLAC Merger) and shares of Pubco Class A Stock received by Seller	The Sponsor and Seller	The earlier of (i) the Anniversary Release; provided, that if the VWAP of Pubco Class A Stock equals or exceeds $12.50 per share for any 20 consecutive trading days following the Closing, the Anniversary Release will be deemed to occur at 11:59 p.m. New York City time on such 20th consecutive trading day and (ii) the date on which Pubco consummates a liquidation, merger, share exchange, reorganization or other similar transaction after the Closing which results in all of Pubco’s shareholders having the right to exchange their shares of Pubco Stock for cash, securities or other property.	Transfers permitted (a) to MLAC’s or Pubco’s officers or directors, any current or future affiliates or family members of any of such officers or directors, any equity holders of such person, any current or future affiliates of such person or as a gift to a charitable organization, (b) in the case of an individual, by gift to a member of one of the members of the individual’s immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, a current or future affiliate of such person or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by virtue of the laws of jurisdiction of formation of such person or such person’s governing documents upon its dissolution; (f) transfers to satisfy any U.S. federal, state, or local income tax obligations of Holder (or its direct or indirect owners) to the extent necessary to cover any tax liability as a direct result of the Transactions, or (g) in the form of a pledge of Restricted Securities (as

xxxviii

Subject Securities	Persons Subject to Restrictions	Expiration Date	Exceptions to Transfer Restrictions
			defined therein) in a bona fide transaction as collateral to secure obligations pursuant to lending or other financing arrangements between a holder (or its affiliates), on the one hand, and a third party, on the other hand, for the benefit of such holder and/or its affiliates; provided, however, that during the lock-up period such third party shall not be permitted to foreclose upon such Restricted Securities or otherwise be entitled to enforce its rights or remedies with respect to the Restricted Securities, including, without limitation, the right to vote, transfer or take title to or ownership of such Restricted Securities; provided, however, that these permitted transferees must enter into a written agreement agreeing to be bound by these same transfer restrictions.

Q: Did the MLAC Board obtain a fairness opinion (or any similar report or appraisal) in determining whether or not to proceed with the Business Combination?

A: No. The MLAC Board did not obtain a fairness opinion (or any similar report or appraisal) in connection with its determination to approve the Business Combination. However, MLAC’s management, the members of the MLAC Board and the other representatives of MLAC have experience in evaluating the operating and financial merits of cryptocurrency companies and reviewed certain financial information of Pubco and the Company and other relevant financial information selected based on the experience and the professional judgment of MLAC’s management team. Accordingly, investors will be relying solely on the judgment of the MLAC Board in valuing the Company’s business and accordingly, investors assume the risk that the MLAC Board may not have properly valued such business. For more information, see the risk factor entitled “Risk Factors — Risks Related to the Business Combination — Neither the MLAC Board nor any committee thereof obtained a fairness opinion (or any similar report or appraisal) in determining whether or not to pursue the Business Combination. Consequently, MLAC Shareholders have no assurance from an independent source that the number of shares of Pubco Stock to be issued to Seller and MLAC Shareholders in the Business Combination is fair to MLAC — and, by extension, MLAC Shareholders — from a financial point of view.”

xxxix

Q: What factors did the MLAC Board consider in connection with its decision to recommend voting in favor of the Business Combination?

A: The MLAC Board considered a variety of factors in connection with its evaluation of the Business Combination. In light of the complexity of those factors, the MLAC Board, as a whole, did not consider it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it took into account in reaching its decision. Individual members of the MLAC Board may have given different weight to different factors. Certain information presented in this section is forward- looking in nature and, therefore, should be read in light of the factors discussed under “Cautionary Note Regarding Forward-Looking Statements.” Before reaching its decision, the MLAC Board reviewed the information provided to it by its management, representatives of the Sponsor and MLAC’s legal and financial advisors, as further described in the section entitled “The Business Combination Proposal — MLAC Board’s Reasons for Approval of the Business Combination” below.

• Neither the MLAC Board nor any committee thereof obtained a fairness opinion (or any similar report or appraisal) in determining whether to pursue the terms of the Business Combination (including the consideration to be received by MLAC Shareholders and members of the Company).

• The MLAC Board determined that pursuing a potential business combination with Pubco and the Company would be an attractive opportunity for MLAC and the MLAC Shareholders, which determination was based on a number of factors. See the section titled “The Business Combination Proposal — MLAC Board’s Reasons for Approval of the Business Combination.”

Q: What are the U.S. federal income tax consequences of the Domestication and MLAC Merger to me?

A: It is the opinion of MLAC’s counsel, Ellenoff Grossman & Schole LLP (“EGS”), that (i) the Domestication will qualify as a reorganization within the meaning of Section 368(a)(1)(F) of the Code and (ii) the Business Combination Transactions taken together, will be treated as an integrated transaction that is described in Section 351 of the Code, in each case for U.S. federal income tax purposes. Consequently, except as otherwise provided below in the sections entitled “U.S. Federal Income Tax Considerations” a U.S. Holder will not recognize gain or loss upon the exchange of its Public Shares solely for shares of Pubco Class A Stock pursuant to the Domestication and the MLAC Merger. A U.S. Holder’s aggregate tax basis in the shares of Pubco Class A Stock received in connection with the Domestication and the MLAC Merger will generally be the same as its aggregate tax basis in the Public Shares surrendered in the transaction. In addition, the holding period of shares of Pubco Class A Stock received in the Domestication and the MLAC Merger will generally include the holding period of Public Shares surrendered in the Domestication and the MLAC Merger.

For additional discussion of the U.S. federal income tax treatment of the Domestication and the MLAC Merger, see the section entitled “U.S. Federal Income Tax Considerations.”

Q: How will the Business Combination affect my MLAC Class A Ordinary Shares?

A: Pursuant to the Business Combination Agreement, (a) prior to the Closing, MLAC will effect the Domestication, pursuant to which MLAC will transfer by way of continuation to and become a Delaware corporation, (b) at least two (2) hours after the Domestication, and as part of the Closing, MLAC Merger Sub will merge with and into MLAC, with MLAC continuing as the surviving company and a wholly-owned subsidiary of Pubco, as a result, MLAC shareholders will receive one (1) share of non-voting Pubco Class A Stock for each MLAC Class A Ordinary Share held by such shareholder, and each holder of MLAC Rights will receive one (1) share of Pubco Class A Stock in exchange for every ten (10) MLAC Rights held by such holder, see “Description of Pubco Securities.”

Q: How many votes per share is each class of Pubco Stock entitled?

A: Upon Closing, the voting rights for each class of Pubco Stock will be as follows:

• Each holder of Pubco Class A Stock will have no voting rights (unless required under the Delaware General Corporation Law (“DGCL”)), until all shares of Pubco Class B Stock are canceled;

xl

• Each holder of Pubco Class B Stock will be entitled to one vote for each share of Pubco Class B Stock held of record by such holder on all matters on which stockholders are generally entitled to vote;

• If you hold MLAC Class A Ordinary Shares, you will not have any voting rights once you receive Pubco Class A Stock in connection with the MLAC Merger; and

• Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights.

Q: What are the risks associated with the multiple class share structure with voting and nonvoting stock?

A: Pubco will have two classes of common stock after Closing, with Pubco Class A Stock having no voting rights and Pubco Class B Stock having voting rights. Only Seller Related Parties and their permitted transferees will be permitted to own shares of Pubco Class B Stock. As a result, Pubco will be a controlled company under Nasdaq listing standards after Closing, with most decisions of Pubco being controlled by Seller Related Parties and other decisions requiring approval of Seller Related Parties or their respective director designees. Accordingly, Public Shareholders will be subject to the decisions of Pubco’s controlling shareholders and if they are unhappy with any decisions made, they only be able to sell their shares of Pubco Class A Stock, which could potentially be at a loss. At Closing, Seller Related Parties will be the beneficial owners of 100% of the voting rights of Pubco Class B Stock.

This concentrated control could delay, defer or prevent a change of control, merger, consolidation or sale of all or substantially all of Pubco’s assets, or conversely this concentrated control could result in the consummation of such a transaction that the holders of Pubco Class A Stock do not support. See “Risk Factors” for a more detailed discussion of these risks.

Q: Why is MLAC proposing the Nasdaq Proposal?

A: Under Nasdaq Rule 5635(a), shareholder approval is required prior to the issuance of securities in connection with the acquisition of another company if such securities are not issued in a public offering and (i) have, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding before the issuance of ordinary shares (or securities convertible into or exercisable for ordinary shares); or (ii) the number of ordinary shares to be issued is or will be equal to or in excess of 20% of the number of ordinary shares outstanding before the issuance of the share or securities.

Under Nasdaq Rule 5635(b), shareholder approval is required when any issuance or potential issuance will result in a “change of control” of the issuer. Although Nasdaq has not adopted any rule on what constitutes a “change of control” for purposes of Rule 5635(b), Nasdaq has previously indicated that the acquisition of, or right to acquire, by a single investor or affiliated investor group, as little as 20% of the ordinary shares (or securities convertible into or exercisable for ordinary shares) or voting power of an issuer could constitute a change of control.

Under Nasdaq Rule 5635(d), shareholder approval is required for a transaction other than a public offering involving the sale, issuance or potential issuance by an issuer of ordinary shares (or securities convertible into or exercisable for ordinary shares) at a price that is less than the lower of (the “Minimum Price”): (i) the Nasdaq official closing price immediately preceding the signing of the binding agreement; or (ii) the average Nasdaq official closing price of the common stock for the five trading days immediately preceding the signing of the binding agreement if the number of shares of common stock to be issued is or may be equal to 20% or more of the common stock, or 20% or more of the voting power, outstanding before the issuance.

Additionally, upon the consummation of the Business Combination and based on the assumptions described elsewhere in this proxy statement/prospectus, Pubco expects to issue, (i) shares of Pubco Class A Stock in connection with the Business Combination, (ii) shares of Pubco Class A Stock in connection with the Company Unit Subscription, (iii) shares of Pubco Class A Stock and Pubco Class B Stock in connection with the Dragonfly Contribution, (iv) shares of Pubco Class A Stock in connection with the Foundation Transaction, (v) shares of Pubco Class A Stock that will, upon Closing, be reserved for issuance pursuant to the Incentive Plan, and (vi) shares that may be issued to the Sponsor and its Affiliates from conversion of the Working Capital Loans. For further details, see “The Business Combination Agreement,” “The Business Combination Proposal — Post-Closing Pubco Board of Directors and Executive Director — Investments and Additional Permitted Financing” and “Executive and Director Compensation — Material Terms of the Incentive Plan.” Accordingly, the aggregate number of (i) shares of Pubco Class A Stock and Pubco Class B Stock that Pubco will issue in connection with the Business Combination will, in the aggregate,

xli

exceed 20% of both the voting power and the number of MLAC Ordinary Shares outstanding before such issuance and will result in a change of control of MLAC. For these reasons, MLAC is seeking the approval of MLAC Shareholders for the issuance of the shares of Pubco Class A Stock and Pubco Class B Stock in connection with the Business Combination pursuant to Nasdaq Rules 5635(a) and (b). For further details, see “The Nasdaq Proposal.”

Q: What happens if I sell my Public Shares before the Meeting?

A: The Record Date is earlier than the date of the Meeting. If you transfer your Public Shares after the Record Date but before the date of the Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the Meeting. However, you will not be able to seek redemption of your Public Shares because you will no longer be able to deliver them for cancellation upon consummation of the Business Combination in accordance with the provisions described herein. If you transfer your Public Shares prior to the Record Date, you will have no right to vote those shares at the Meeting.

Q: What happens if MLAC Shareholders vote against the Business Combination Proposal?

A: Pursuant to the MLAC Memorandum and Articles, if the Business Combination Proposal is not approved and MLAC does not otherwise consummate an alternative business combination by the end of the Combination Period, MLAC will be required to dissolve and liquidate the Trust Account by returning the then remaining funds in the Trust Account, including interest (net of taxes payable), to the Public Shareholders in accordance with the MLAC Memorandum and Articles.

Q: Do I have redemption rights?

A: Pursuant to the MLAC Memorandum and Articles, holders of Public Shares may elect to have their Public Shares redeemed for cash at the then-applicable redemption price calculated as of two business days prior to the Closing. As of the date of this proxy statement/prospectus, based on funds in the Trust Account of approximately $244.2 million as of May 4, 2026, this would have amounted to approximately $10.62 per share (including interest earned on the funds held in the Trust Account but less taxes payable). If a holder exercises its redemption rights, then such holder will be exchanging its Public Shares for cash. Such a holder will be entitled to receive cash for its Public Shares only if it properly demands redemption and delivers its shares (either physically or electronically) to CST prior to the Meeting. See the section titled “Extraordinary General Meeting of MLAC Shareholders — Redemption Rights” for the procedures to be followed if you wish to redeem your Public Shares for cash. In connection with the MLAC IPO, the Sponsor and its Affiliates agreed to waive any redemption rights with respect to any MLAC Ordinary Shares held by them in connection with the completion of the Business Combination. Such waivers are standard in transactions of this type and the Sponsor and its Affiliates did not receive separate consideration for the waiver.

Q: Will how I vote affect my ability to exercise redemption rights?

A: No. You may exercise your redemption rights whether or not you are a holder of Public Shares on the Record Date (so long as you are a holder at the time of exercise), or whether or not you are a holder and vote your Public Shares on the Business Combination Proposal (for or against) or any other Proposal. As a result, the Business Combination Agreement can be approved by Public Shareholders who will redeem their Public Shares, leaving Public Shareholders who choose not to redeem their Public Shares holding shares in a company with a potentially less liquid trading market, fewer shareholders, potentially less cash and the potential inability to meet the listing standards of Nasdaq or another national securities exchange.

Q: How do I exercise my redemption rights?

A: In order to exercise your redemption rights, you must, prior to 5:00 p.m., Eastern Time, on             , 2026 (two (2) business days before the Meeting), tender your Public Shares physically or electronically and submit a request in writing that MLAC redeem your Public Shares for cash to CST, MLAC’s transfer agent, at the following address:

Continental Stock Transfer & Trust Company
One State Street Plaza, 30^th Floor

New York, New York 10004

If you hold Public Shares in “street name,” you will have to coordinate with your broker to have your shares certificated or delivered electronically. Certificates that have not been tendered (either physically or electronically) in accordance with these procedures will not be redeemed. There is a nominal cost associated with this tendering process and the act of certificating the shares or delivering them through the DTC’s DWAC system.

A Public Shareholder may not withdraw a redemption request once submitted to MLAC unless the MLAC Board determines (in their sole discretion) to permit the withdrawal of such redemption request (which they may do in whole or in part). Subject to the forgoing, if you delivered your Public Shares for redemption to CST and decide within the required timeframe not to exercise your redemption rights, you may request that CST return the shares (physically or electronically). You may make such request by contacting CST at the phone number or address listed under the question “Who can help answer my questions?” below.

Any holder of Public Shares (whether or not they are a holder on the Record Date) will be entitled to demand that their Public Shares be redeemed for a pro rata portion of the amount then in the Trust Account (which was approximately $244.2 million as of May 4, 2026, or approximately $10.62 per share (including interest earned on the funds held in the Trust Account but less taxes payable). Such amount, less any owed but unpaid taxes on the funds in the Trust Account, will be paid promptly upon consummation of the Business Combination. Your vote on any Proposal will have no impact on the amount you will receive upon exercise of your redemption rights.

If a holder of Public Shares properly makes a demand for redemption as described above, then, if the Business Combination is consummated, MLAC will convert these shares into a pro rata portion of funds deposited in the Trust Account. If you exercise your redemption rights, then you will be exchanging your Public Shares for cash and will not be entitled to shares of Pubco Class A Stock upon consummation of the Business Combination. If the Business Combination is not approved or completed for any reason, then holders of Public Shares who elected to exercise their redemption rights would not be entitled to convert their Public Shares for the applicable pro rata share of the Trust Account. In such case, MLAC will promptly return any Public Shares delivered by Public Shareholders and such holders may only share in the assets of the Trust Account upon the consummation of another business combination or the liquidation of MLAC. This may result in holders receiving less than they would have received if the Business Combination was completed and they exercised redemption rights in connection therewith.

Notwithstanding the foregoing, the MLAC Memorandum and Articles provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than 15% of the Public Shares in the aggregate, without the prior consent of MLAC.

Q: What are the U.S. federal income tax consequences of exercising my redemption rights?

A: Holders of Public Shares who exercise their redemption rights to receive cash will be considered for U.S. federal income tax purposes to have made a sale or exchange of the tendered shares, or will be considered for U.S. federal income tax purposes to have received a distribution with respect to such shares that may be treated as: (i) dividend income, (ii) a non-taxable recovery of basis or (iii) gain. See the section entitled “U.S. Federal Income Tax Considerations — U.S. Holders” and “U.S. Federal Income Tax Considerations — Non-U.S. Holders.”

Q: Do I have appraisal rights if I object to the proposed Business Combination?

A: MLAC Shareholders do not have appraisal rights in connection with the Business Combination under the DGCL or the Cayman Act.

In addition, Public Shareholders are still entitled to exercise the rights of redemption as detailed in this proxy statement/prospectus and the redemption proceeds payable to Public Shareholders who exercise such redemption rights will represent the fair value of those shares. For a discussion about the Public Shareholders’ redemption rights, please see “Extraordinary General Meeting of MLAC Shareholders — Redemption Rights.”

xliii

Q: What happens to the funds deposited in the Trust Account after the consummation of the Business Combination?

A: If the Business Combination is consummated, the funds held in the Trust Account will be used to pay Public Shareholders who properly exercise their redemption rights. The remaining amount will be released to MLAC and used to:

• pay certain fees, costs and expenses (including taxes, regulatory fees, legal fees, accounting fees, printer fees and other professional fees) that were incurred by MLAC and Pubco in connection with the transactions contemplated by the Business Combination and pursuant to the terms of the Business Combination Agreement; and

• provide for general corporate purposes of Pubco, including, but not limited to, working capital for operations and to purchase additional AVAX.

Q: What happens if a substantial number of Public Shareholders vote in favor of the Business Combination Proposal and exercise their redemption rights?

A: Unlike some other blank check companies which require Public Shareholders to vote against a business combination in order to exercise their redemption rights, Public Shareholders may vote in favor of the Business Combination and exercise their redemption rights. Accordingly, the Business Combination may be consummated even though the funds available from the Trust Account and the number of Public Shareholders are substantially reduced as a result of redemption by Public Shareholders. With fewer Public Shares and Public Shareholders, the trading market for shares of Pubco Class A Stock may be less liquid than the market for Public Shares was prior to the Business Combination, and Pubco may not be able to meet the listing standards for Nasdaq or another national securities exchange. In addition, with less funds available from the Trust Account, the working capital infusion from the Trust Account into Pubco’s business will be reduced.

Q: What happens if the Business Combination is not consummated?

A: If MLAC does not complete the Business Combination with the Company or another business combination by the end of the Combination Period, MLAC must: (i) redeem 100% of the issued and outstanding Public Shares, at a per-share price, payable in cash, equal to the amount then held in the Trust Account (which was approximately $244.2 million as of May 4, 2026, or approximately $10.62 per share (including interest earned on the funds held in the Trust Account but less taxes payable and less up to $100,000 of interest to pay dissolution expenses) divided by the number of Public Shares then outstanding, (ii) cease all operations except for the purpose of winding up, and (iii) subject to the approval of its remaining shareholders and its board of directors, dissolve and liquidate. For more information about the liquidation process, see “Information About MLAC — Redemption Rights for Public Shareholders upon Completion of the Business Combination — Redemption of Public Shares and Liquidation if no Initial Business Combination.”

Q:When do you expect the Business Combination to be completed?

A: It is currently anticipated that the Business Combination will be consummated promptly following the Meeting, which is set for            , 2026. However, the Meeting could be adjourned or postponed, as described above. In addition, the Business Combination Agreement may be terminated by the parties upon the occurrence of certain events. For a description of the conditions for the completion of the Business Combination, see the section entitled “The Business Combination Proposal — Conditions to the Parties’ Obligations to the Closing.”

Q.Why does MLAC need to hold an annual meeting?

A. The Meeting is also being held, in part, to satisfy the annual meeting requirement of Nasdaq which requires that MLAC hold an annual meeting of shareholders during each fiscal year. In addition to sending the shareholders this proxy statement/prospectus, MLAC will also send its Annual Report on Form 10-K for the fiscal year ended December 31, 2025 when available.

Astral is a Delaware limited partnership whose general partner is Astral Horizon GP, LLC. The limited partners of Astral are certain senior managers and employees of the Seller and the general partners of the DVs. Astral Horizon GP, LLC is managed by some of the same individuals who serve as the managers of the general partners of the DVs. Accordingly, Astral is a related party to the Seller Related Parties by virtue of common management and overlapping ownership among their respective principals. The 4,000,000 newly issued Pubco Class A Stock Astral is entitled to receive as additional consideration for the Company Merger (the “Additional Merger Consideration Shares”) are being issued to Astral in consideration for advisory and strategic services provided by Astral’s limited partners in connection with the structuring and execution of the Business Combination and the establishment of Pubco. Such services included, but were not limited to:

(i) Executive Recruitment: Astral’s limited partners assisted in identifying, evaluating, and recruiting the Chief Executive Officer of Pubco; and

(ii) Tax and Corporate Structuring Advisory: Astral’s limited partners provided strategic advice regarding aspects of the tax and corporate structuring of the Business Combination and post-Closing operations of Pubco.

Consequently, (i) on January 13, 2026, the Parties entered into the First Amendment to the Business Combination Agreement, pursuant to which, inter alia, the 4,000,000 Additional Merger Consideration Shares (i.e., the 2,000,000 Astral Post-Closing Shares and the 2,000,000 Astral Earnout Shares) will be issued, on the Company Merger Effective Date, to Astral (the Astral Earnout Shares being held in escrow for the Escrow Period only to be released in accordance with the Astral Escrow Agreement), and (ii) on March 17, 2026, the Parties entered into the Second Amendment to the Business Combination Agreement, pursuant to which the issuance by Pubco to Astral of the 2,000,000 Astral Post-Closing Shares will occur on the thirtieth (30th) calendar day following the Closing Date, rather than on the Company Merger Effective Date.

Pursuant to the Business Combination Agreement, and subject to the terms and conditions set forth therein, (a) prior to the Closing, MLAC will effect the Domestication, pursuant to which MLAC will transfer by way of continuation to and become a Delaware corporation, (b) at least two hours after the Domestication, the MLAC Merger will be completed, pursuant to which MLAC Merger Sub will merge with and into MLAC, with MLAC continuing as the surviving company and a wholly owned subsidiary of Pubco and with MLAC Shareholders receiving one (1) share of Pubco Class A Stock for each MLAC Class A Ordinary Share held by such MLAC Shareholder, and with each holder of MLAC Rights receiving one (1) share of Pubco Class A Stock in exchange for every ten (10) MLAC Rights held by such holder, and (c) the Company Merger will be completed, pursuant to which Company Merger Sub will merge with and into the Company, with the Company continuing as the surviving company, and with (i) each Company Member other than Seller Related Parties receiving one (1) share of Pubco Class A Stock for each Company Unit held immediately prior to the effective time of the Company Merger, (ii) Seller Related Parties receiving one (1) share of Pubco Class A Stock and one (1) share of Pubco Class B Stock for each Company Unit held and (iii) Astral receiving the Additional Merger Consideration Shares, as follows: (i) 2,000,000 shares of Pubco Class A Stock (the “Astral Escrow Shares”) will be issued at the Company Merger Effective Time and deposited into an escrow account with the Trustee (or another escrow agent reasonably acceptable to Seller and Pubco) (the “Astral Escrow Account”), and (ii) 2,000,000 shares of Pubco Class A Stock (the “Astral Post-Closing Shares”) will be issued and deposited into Astral’s security account on the thirtieth (30^th) calendar day following the Closing Date, rather than on the Company Merger Effective Date.

The Astral Escrow Shares will be released in tranches, all as provided in the Business Combination Agreement and the escrow agreement that will be entered into by and between Seller, Pubco and the escrow agent in a form to be mutually agreed upon by the parties prior to the Closing (the “Astral Escrow Agreement”). In particular, the Astral Escrow Shares will (i) vest and be released to

Astral upon the achievement of one or more Triggering Events (as defined under the Business Combination Agreement) or the occurrence of a Change in Control, and/or (ii) be transferred to Pubco in the event that, within the earn out period ending on the fifth (5^th) anniversary of the Closing Date, all of the Triggering Events have not been achieved by Pubco and a Change in Control has not occured.

By virtue of the MLAC Merger:

(1) immediately prior to the MLAC Merger Effective Time, (i) each MLAC Unit issued and outstanding immediately prior to the MLAC Merger Effective Time, that has not been forfeited in accordance with the Sponsor Support Agreement, shall be automatically subject to the Unit Separation with the holder thereof being deemed to hold one (1) MLAC Class A Ordinary Share and one (1) MLAC Right; and (ii) the MLAC Class A Ordinary Shares (other than the shares in respect of which its holder has validly exercised its right of redemption) and MLAC Right underlying the MLAC Unit held or deemed to be held following the Unit Separation shall be converted in accordance with the applicable terms of limbs (2)(i) and (2)(ii) respectively;

(2) at the MLAC Merger Effective Time:

(i) each issued and outstanding MLAC Right shall be automatically converted into the number of shares of Pubco Class A Stock that would have been received by the holder thereof if the MLAC Right had been converted upon the consummation of a Business Combination in accordance with MLAC’s Organizational Documents, the MLAC IPO Prospectus and the MLAC Rights Agreement into MLAC Class A Ordinary Shares, but for such purposes treating it as if (a) such Business Combination had occurred immediately prior to the MLAC Merger Effective Time and (b) the MLAC

(v) each issued and outstanding MLAC Merger Sub Membership Interest shall be converted into an equal number of ordinary shares, par value $0.0001, of the MLAC Surviving Subsidiary,with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding share capital of the MLAC Surviving Subsidiary.

At the MLAC Merger Effective Time, each issued and outstanding Public Share in respect of which the holder thereof has validly exercised redemption rights pursuant to and in accordance with the MLAC Memorandum and Articles will be canceled, and those MLAC Shareholders will only have the right to receive a pro rata share of the redemption amount.

If there are any MLAC Ordinary Shares that are owned by MLAC as treasury shares, such treasury shares will be automatically canceled without any conversion thereof or payment therefor.

For illustrative purposes, based on funds in the Trust Account of approximately $241.2 million as of December 31, 2025 and $244.2 million as of May 4, 2026, the estimated per share redemption prices would have been approximately $10.49 per share and $10.62 per share, respectively (including interest earned on the funds held in the Trust Account but less taxes payable). As of December 31, 2025 and May 4, approximately 36.5% and 19.4%, respectively, of the AVAX holdings of AVAT were unlocked and unstaked, available to be liquidated as needed to fund transaction or other operating expenses.

Ownership of Pubco After the Transactions

Upon the completion of the Business Combination, and assuming, among other things, that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination, (i) Public Shareholders (including MLAC Right Holders) will own approximately 41.8% of the issued and outstanding shares of Pubco Class A Stock, (ii) the Company Unit Investors will own approximately 35.7% of the issued and outstanding shares of Pubco Class A Stock, (iii) the Sponsor and its Affiliates will own approximately 4.6% of the issued and outstanding shares of Pubco Class A Stock, out of which the Sponsor Earnout Shares will represent approximately 2.6% of the issued and outstanding shares of Pubco Class A Stock, (iv) Seller Related Parties will own approximately 9.6% of the issued and outstanding shares of Pubco Class A Stock and 100% of the issued and outstanding shares of Pubco Class B Stock, (v) Astral will own approximately 3.3% of the issued and outstanding shares of Pubco Class A Stock, out of which the Astral Post-Closing Shares will represent approximately 3.3% of the issued and outstanding shares of Pubco Class A Stock and (vi) the Foundation will own approximately 5.0% of the issued and outstanding shares of Pubco Class A Stock. Each holder of shares of Pubco Class A Stock will have no voting rights, except (i) as required by the DGCL or (ii) on any matter that adversely affects them relative to holders of any other class of stock of Pubco, until all shares of Pubco Class B Stock are canceled. Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights. Each holder of shares of Pubco Class B Stock will be entitled to one vote for each share of Pubco Class B Stock held of record by such

9

holder on all matters on which stockholders are generally entitled to vote. See “Risk Factors — Seller, whose interests may conflict with yours, can individually exercise significant influence over Pubco. You will have no voting rights of Pubco Class A Stock except as required by the DGCL and the concentrated ownership of Pubco Stock may prevent you and other shareholders from influencing significant decisions in the very limited circumstances in which the DGCL will give you the right to vote and may prevent or discourage unsolicited acquisition proposals or offers for Pubco Stock, and that may adversely affect the trading price of Pubco Class A Stock.”

If any of the Public Shareholders exercise their redemption rights, the percentage of the issued and outstanding shares of Pubco Class A Stock held by the Public Shareholders will decrease and the percentages of issued and outstanding shares of Pubco Class A Stock held by the Company Unit Investors, the Sponsor, Seller Related Parties, Astral, and the Foundation each increase relative to the percentage held if none of the Public Shares are redeemed unless the Class A Pubco Stock cease to be nonvoting securities, in which case, the Foundation’s percentage ownership will decrease relative to the percentage held if none of the Public Shares are redeemed and the Foundation will receive a number of pre-funded warrants convertible into Pubco Class A Stock in accordance with the Token Sale Agreement, the Contribution Agreement and the Foundation warrant agreement so that its beneficial ownership in Pubco does not exceed the Maximum Percentage.

The tables below illustrate varying beneficial ownership levels in Pubco immediately upon Closing, assuming No Redemptions by Public Shareholders, 25% Redemptions by Public Shareholders (5,727,000 MLAC Class A Ordinary Shares are redeemed by Public Shareholders), 50% Redemptions by Public Shareholders (11,452,023 MLAC Class A Ordinary Shares are redeemed by Public Shareholders), 75% Redemptions by Public Shareholders (17,178,034 MLAC Class A Ordinary Shares are redeemed by Public Shareholders) and Maximum Redemptions by Public Shareholders (22,904,656 MLAC Class A Ordinary Shares are redeemed by Public Shareholders). If any of these assumptions are not correct, these percentages will be different.

(1) NTBV is calculated as total assets minus total liabilities and MLAC Class A Ordinary Shares subject to redemption as of December 31, 2025.

11

(2) NTBV is adjusted for (i) payments from the Trust Account at different levels of redemptions to Public Shareholders at the $10.55 per share redemption price as of February 28, 2026; (ii) transaction costs that have not been recorded on MLAC’s financial statements as of December 31, 2025; and (iii) the portion of the deferred underwriter fee to be forfeited by BTIG, which will have an impact on the calculation of NTBV upon the Closing.

(3) Dilution is calculated by subtracting the NTBV per share as of December 31, 2025, as adjusted, from the $10.00 MLAC IPO per share price for the Public Shares.

MLAC issued the Public Shares in the MLAC IPO at $10.00 per share. After giving effect to the issuance of the 23,000,000 Public Shares in the MLAC IPO and the 310,000 MLAC Private Placement Shares issued to BTIG in the MLAC Private Placement, which remain issued and outstanding, there were 23,310,000 MLAC Class A Ordinary Shares issued and outstanding.

In connection with the Business Combination, assuming its consummation in accordance with the Business Combination Agreement, immediately after the Closing, Pubco is expected to have outstanding 60,468,670 shares of Pubco Class A Stock, including (i) 3,000,000 Pubco Class A Stock to be issued to the Foundation pursuant to the Foundation Transaction, (ii) 5,805,638 Pubco Class A Stock to be issued to the Seller Related Parties pursuant to the Seller Related Parties receiving one share of Pubco Class A Stock for each Company Unit held, (iii) 2,000,000 Pubco Class A Stock to be issued to Astral as additional consideration for the Company Merger, (iv) 2,800,000 Pubco Class A Stock to be issued to the Sponsor and Affiliates in exchange for MLAC Founder Shares, (v) 25,300,000 Pubco Class A Stock to be issued pursuant to each Public Shareholder receiving one (1) share of Pubco Class A Stock for each MLAC Class A Ordinary Share held by such shareholder, including 2,300,000 shares underlying the MLAC Public Rights, and (vi) 21,563,032 shares of Pubco Class A Stock to be issued in connection with the Company Unit Investors receiving one share of Pubco Class A Stock for each Company Unit held immediately prior to the effective time of the Company Merger. These shares outstanding also assume, among other things, that no shares of Pubco Class A Stock are issued pursuant to the Incentive Plan and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements. The tabular disclosure includes presentations of information at various illustrative redemption levels consistent with the “No Redemptions,” “25% Redemptions,” “50% Redemptions,” “75% Redemptions” and “Maximum Redemptions” scenarios further described in the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information.”

For purposes of Item 1604(c)(1) of Regulation S-K, Pubco would have 60,468,670 total shares of Pubco Class A Stock outstanding immediately after giving effect to the Business Combination under the “No Redemptions” scenario based on the assumptions set forth in the preceding paragraph and as further described above. Where there are no redemptions of Public Shares prior to the Closing, MLAC valuation is based on the $10.00 issuance price per Public Share in the MLAC IPO and is therefore calculated as $10.00 (MLAC per share MLAC IPO price) multiplied by 60,468,670 shares, or $604,686,700. The following table illustrates the valuation at the $10.00 issuance price per share in the MLAC IPO for each redemption scenario:

	Assuming		Assuming		Assuming		Assuming		Assuming
	No		25%		50%		75%		Maximum

(1) Assumes each Company Unit will be redeemed for one share of Pubco Class A Stock and no issuance of Adjustment Units.

(2) Includes 2,800,000 MLAC Founder Shares (including the 1,600,000 Sponsor Earnout Shares) (after accounting for the surrender of 4,387,500 MLAC Founder Shares by the Sponsor, the surrender of 495,000 Private Placement Shares held by the Sponsor, and the surrender of 310,000 Private Placement Shares held by BTIG).

(3) Includes the 2,547,252 Company Units issued to Dragonfly Ventures L.P., 3,258,386 Company Units issued to Dragonfly Ventures II, L.P.

(4) Includes the 2,000,000 Astral Post-Closing Shares. Does not include the Astral Earnout Shares, which will be held in escrow for the Escrow Period and may only be released to Astral upon the achievement of certain Triggering Events in accordance with the Astral Escrow Agreement.

(5) Up to 3,000,000 of Pubco Class A stock will be issued to the Foundation to the Foundation pursuant to the Foundation Transaction. In the event the Pubco Class A Stock cease to be nonvoting securities, the Foundation will forfeit a number of its Pubco Class A Stock and will receive from Pubco a number of pre-funded warrants convertible into Pubco Class A Stock prior to the time the Pubco Class A Stock cease to be nonvoting securities so that the Foundation’s beneficial ownership in Pubco does not exceed the Maximum Percentage.

The foregoing required disclosure is not a guarantee that the trading price of Pubco Class A Stock will not be below the offering price in the MLAC IPO, nor is the required disclosure a guarantee that Pubco will attain any of the levels of valuation presented.

The above discussion and table are based on 30,992,500 MLAC Ordinary Shares outstanding on December 31, 2025.

The above discussion and table also exclude potential dilutive effects associated with future issuances or grants of equity or equity-linked securities by Pubco pursuant to the Incentive Plan expected to be adopted in connection with the Closing and that no Adjustment Units are issued.

The aforementioned equity issuances are not the only sources of potential dilution to the relative ownership percentage associated with shares of Pubco Class A Stock held by non-redeeming Public Shareholders after the Closing; any additional equity and equity-linked issuances by Pubco may result in additional dilution to Public Shareholders’ percentage ownership in Pubco, potentially significantly, and may have other effects, as described above and as further described in the “Risk Factors” section of this proxy statement/prospectus.

All of the relative percentages above are for illustrative purposes only and are based upon certain assumptions as described above. Should one or more of the assumptions prove incorrect, actual ownership percentages may vary materially from those described in this proxy statement/prospectus as anticipated, believed, estimated, expected or intended. See “Unaudited Pro Forma Condensed Combined Financial Information.”

Date, Time and Place of the Extraordinary General Meeting in lieu of an Annual General Meeting of MLAC Shareholders

The Meeting will be held on        , 2026 at          , Eastern Time, at 1345 Avenue of the Americas, New York, NY 10105 and virtually via live webcast on the Internet at https://www.cstproxy.com/mountainlakeacquisition/2026. You will be able to attend, vote your shares and submit questions during the Meeting via a live webcast available at https://www.cstproxy.com/mountainlakeacquisition/2026.

You or your proxyholder will be able to attend and vote at the Meeting by visiting https://www.cstproxy.com/mountainlakeacquisition/2026 and using a control number assigned by CST. To register and receive access to the Meeting, registered shareholders and beneficial owners (those holding shares through a stock brokerage account or by a bank or other holder of record) will need to follow the instructions applicable to them provided in this proxy statement/prospectus. You will need the voter control number included on your proxy card in order to be able to vote your shares or submit questions during the Meeting. If you do not have a voter control number, you will be able to listen to the Meeting only and you will not be able to vote or submit questions during the Meeting.

Voting Power; Record Date

MLAC Shareholders will be entitled to vote or direct votes to be cast at the Meeting if they owned MLAC Ordinary Shares at the close of business on        , 2026, which is the Record Date for the Meeting. MLAC Shareholders are entitled to one vote at the Meeting for each MLAC Ordinary Share held as of the Record Date. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the Meeting and vote, obtain a proxy from your broker, bank or nominee.

As of the close of business on the Record Date, there were 30,992,500 MLAC Ordinary Shares issued and outstanding, consisting of 23,805,000 MLAC Class A Ordinary Shares and 7,187,500 MLAC Class B Ordinary Shares. Of these shares, 23,000,000 were Public Shares.

Quorum and Vote of MLAC Shareholders

A quorum of MLAC Shareholders is necessary to hold a valid meeting. A quorum for the Meeting consists of the holders of one-third of the then issued and outstanding MLAC Ordinary Shares (whether in person or by proxy). As of the Record Date, MLAC Shareholders holding 10,330,834 MLAC Ordinary Shares would be required to achieve a quorum at the Meeting without the MLAC Ordinary Shares held by the Sponsor. In addition to the MLAC Ordinary Shares held by the Sponsor, which represent approximately 24.8% of the issued and outstanding MLAC Ordinary Shares, MLAC will need MLAC Shareholders holding 2,648,334 MLAC Ordinary Shares, or 11.5%, of the 23,000,000 Public Shares represented in person or by proxy at the Meeting to hold a valid quorum.

To pass, each of the Business Combination Proposal, the Nasdaq Proposal, the Director Election Proposal and the Adjournment Proposal requires an ordinary resolution of MLAC Shareholders, which requires the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). To pass, the Merger Proposal requires a special resolution of MLAC Shareholders, which requires the affirmative vote of at least two-thirds of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). MLAC Shareholders are also being asked to approve by way of ordinary resolutions, on a non-binding advisory basis, each of the Domestication and Organizational Documents Proposals. Although the MLAC Board is asking MLAC Shareholders to approve each of the Domestication and Organizational Documents Proposals on the non-binding advisory basis, regardless of the outcome of the non-binding advisory vote on each of the Domestication and Organizational Documents Proposals, the Amended and Restated Pubco Charter and Pubco’s Amended and Restated Bylaws will take effect upon the Closing if the Business Combination Proposal and the Merger Proposal are approved.

Assuming a quorum is established, an MLAC Shareholder’s failure to vote by proxy or to vote in person (including virtually) at the Meeting will have no effect on the Proposals. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast and will have no effect on any of the Proposals.

16

The Sponsor has agreed to vote its 7,682,500 MLAC Ordinary Shares, representing 24.8% of the issued and outstanding MLAC Ordinary Shares, in favor of each of the Proposals. As a result, with respect to each Proposal that require approval of MLAC Shareholders by an ordinary resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 7,813,751, or 34.0%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposals in order to have such Proposals approved. With respect to each Proposal that requires approval of MLAC Shareholders by a special resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 12,979,167, or 56.4%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposals in order to have such Proposals approved.

Redemption Rights

Pursuant to the MLAC Memorandum and Articles, Public Shareholders may elect to have their Public Shares redeemed for cash at the applicable redemption price per share equal to the quotient obtained by dividing (a) the aggregate amount on deposit in the Trust Account as of two (2) business days prior to the Closing, including interest (net of taxes payable), by (b) the total number of the then issued and outstanding Public Shares. As of the date of this proxy statement/prospectus, based on funds in the Trust Account of approximately $244.2 million as of May 4, 2026, this would have amounted to approximately $10.62 per share (including interest earned on the funds held in the Trust Account but less taxes payable). Public Shareholders may exercise redemption rights whether or not they are holders as of the Record Date and whether or not such shares are voted at the Meeting and whether they vote for or against the Business Combination Proposal. Notwithstanding the foregoing, the MLAC Memorandum and Articles provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than 15% of the Public Shares in the aggregate, without the prior consent of MLAC.

If a Public Shareholder exercises its redemption rights, then such Public Shareholder will be exchanging its Public Shares for cash and will not receive shares of Pubco Class A Stock upon consummation of the Business Combination. Such a Public Shareholder will be entitled to receive cash for its Public Shares only if it properly demands redemption and delivers its shares (either physically or electronically) to CST in accordance with the procedures described herein. See the section titled “Extraordinary General Meeting of MLAC Shareholders — Redemption Rights” for the procedures to be followed if you wish to redeem your Public Shares for cash. In connection with the MLAC IPO, the Sponsor and its Affiliates agreed to waive any redemption rights with respect to any MLAC Ordinary Shares held by them in connection with the completion of the Business Combination. Such waivers are standard in transactions of this type and the Sponsor and its Affiliates did not receive separate consideration for the waiver.

Appraisal Rights

MLAC Shareholders do not have appraisal rights in connection with the Business Combination under the DGCL or the Cayman Act.

In addition, Public Shareholders are still entitled to exercise the rights of redemption as detailed in this proxy statement/prospectus and the redemption proceeds payable to Public Shareholders who exercise such redemption rights will represent the fair value of those shares. For a discussion about the Public Shareholders’ redemption rights, please see “Extraordinary General Meeting of MLAC Shareholders — Redemption Rights.”

Proxy Solicitation

Proxies may be solicited by mail, telephone or in person. MLAC has engaged Sodali & Co as the proxy solicitor to assist in the solicitation of proxies. If an MLAC Shareholder grants a proxy, it may still vote its shares itself if it revokes its proxy before the Meeting. An MLAC Shareholder may also change its vote by entering a new vote by Internet or telephone, submitting a later-dated proxy or attending and voting, virtually via the live webcast or in person, during the Meeting as described in the section of this proxy statement/prospectus titled “Extraordinary General Meeting of MLAC Shareholders — Revoking Your Proxy.”

17

Interests of the Sponsor and its Affiliates in the Business Combination

When Public Shareholders consider the recommendation of the MLAC Board in favor of approval of the Business Combination and other Proposals, Public Shareholders should keep in mind that the Sponsor and its Affiliates have interests in the Proposals that are different from or in addition to (and which may conflict with), the interests of a Public Shareholder as an MLAC Shareholder. These interests include, among other things:

• the Sponsor paid $25,000 for the 7,187,500 MLAC Class B Ordinary Shares. Of these amounts, contemporaneously with the consummation of the Business Combination, the Sponsor shall submit for cancellation 4,387,500 MLAC Class B Ordinary Shares, as a result, the Sponsor will retain the Retained Sponsor Shares. If the Business Combination or another MLAC initial business combination is not consummated by June 16, 2026 (or such other date as approved by the MLAC Shareholders), MLAC will cease all operations except for the purpose of winding up. In such event, the 2,800,000 Retained Sponsor Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be worthless because the holders thereof entered into an agreement waiving entitlement to participate in any redemption or liquidating distributions with respect to such shares. Neither the Sponsor nor any other person received any compensation in exchange for this agreement to waive redemption and liquidation rights. Pursuant to terms of the Insider Letter and the Sponsor Lock-Up Agreement, the Retained Sponsor Shares are subject to a lock-up whereby, subject to certain limited exceptions, the Retained Sponsor Shares are not transferable until the earlier of (A) the Anniversary Release; provided that, if the VWAP of the shares of Pubco Class A Stock equals or exceeds $12.50 per share for any 20 consecutive trading days after Closing, then the Anniversary Release will be deemed to occur at 11:59 p.m. (New York City time) on such 20th consecutive trading day, or (B) subsequent to MLAC’s initial business combination, the date on which Pubco consummates a transaction which results in all of its shareholders having the right to exchange their shares for cash, securities or other properties. (The Sponsor may, on or before the Closing of the Business Combination, distribute some or all of the Retained Sponsor Shares held by it and such distributed Retained Sponsor Shares may be released from lock-up restrictions in connection with applicable stock exchange listing requirements.) In this regard, while the Retained Sponsor Shares are not the same as the MLAC Class A Ordinary Shares, are subject to certain restrictions that are not applicable to the MLAC Class A Ordinary Shares, and may become worthless if MLAC does not complete a business combination by June 16, 2026 (or such other date as approved by the MLAC Shareholders), the aggregate value of the 2,800,000 Retained Sponsor Shares owned by the Sponsor is estimated to be approximately $29.62 million, assuming the per share value of the Retained Sponsor Shares is the same as the $10.58 closing price of the MLAC Class A Ordinary Shares on Nasdaq on May 5, 2026;

• the Sponsor has agreed that the 1,600,000 shares of Pubco Class A Stock to be issued to the Sponsor (of the total 2,800,000 Retained Sponsor Shares it will hold), will be held in escrow during the Earnout Period, subject to early release upon certain price-based Triggering Events. Additionally, any Retained Sponsor Shares that are released from escrow shall not be sold or transferred until the Anniversary Release;

• the 495,000 MLAC Private Placement Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be forfeited immediately prior to the closing pursuant to the Sponsor Support Agreement. The Sponsor purchased the MLAC Private Placement Shares at an aggregate purchase price of $4,950,000, or $10.00 per unit, in the Private Placement consummated simultaneously with the MLAC IPO. The aggregate value of the 495,000 MLAC Private Placement Shares held by the Sponsor is estimated to be approximately $5.24 million, assuming the per unit value of the MLAC Private Placement Shares is the same as the $10.58 closing price of the MLAC Class Ordinary Shares on Nasdaq on May 5, 2026;

• if the proposed Business Combination is consummated, immediately after the Closing the Sponsor and its Affiliates are anticipated to hold 4.9% of the outstanding shares of Pubco Common Stock, based on the assumptions set forth in the section of this proxy statement/prospectus entitled “Share Calculations and Ownership Percentages”, which also incorporate relevant assumptions further described in the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information” and “Beneficial Ownership of Securities” and assuming, among other assumptions further described in aforementioned sections of this proxy statement/ prospectus, no redemptions of Public Shares and no conversion of public share rights or private share rights prior to or in connection with the proposed Business Combination;

• based on the difference in the effective purchase price of $0.003 per share paid for the MLAC Class B Ordinary Shares, as compared to the purchase price of $10.00 per Unit sold in the MLAC IPO, the Sponsor and its members may earn a positive

18

rate of return even if the share price of Pubco after the Closing falls below the price initially paid for the MLAC Units in the MLAC IPO and the unredeeming unaffiliated Public Shareholders experience a negative rate of return following the Closing of the Business Combination;

• if, prior to the Closing, the Sponsor provides working capital loans to MLAC, up to $1,500,000 of which may be convertible into MLAC Private Placement Shares at the option of the Sponsor, such loans may not be repaid if no business combination is consummated and MLAC is forced to liquidate; provided, however, that, as of the date of this proxy statement/prospectus, there are no such working capital loans outstanding;

• unless MLAC consummates an initial business combination, it is possible that MLAC’s officers, directors and the Sponsor may not receive reimbursement for out-of-pocket expenses incurred by them, to the extent that such expenses exceed the amount of available funds not deposited in the Trust Account (provided, however, that, as of the date of this proxy statement/prospectus, MLAC’s officers and directors have not incurred (nor are any of them expecting to incur) out-of-pocket expenses exceeding such funds available to MLAC for reimbursement thereof, but provided, further, that if any such expenses are incurred prior to consummation of the Business Combination, MLAC’s officers, directors and the Sponsor may not receive reimbursement therefor if the proposed Business Combination is not consummated);

• if the Trust Account is liquidated, including in the event MLAC is unable to complete an initial business combination by June 16, 2026 (or such other date as approved by the MLAC Shareholders), the Sponsor has agreed that it will be liable to MLAC, if and to the extent any claims by a third party for services rendered or products sold to MLAC (except for MLAC’s independent auditors) or a prospective target business with which MLAC has entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per share due to reductions in the value of the trust assets less taxes payable, provided, however, that such liability will not apply to any claims by a third party or prospective target business that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable), nor will it apply to any claims under MLAC’s indemnity of the underwriters of the MLAC IPO against certain liabilities, including liabilities under the Securities Act;

• the Sponsor and its Affiliates may benefit from the completion of a business combination and may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to shareholders rather than liquidate;

• MLAC agreed to pay Paul Grinberg (“Mr. Grinberg”), MLAC’s Chairman and Chief Executive Officer and Douglas Horlick, MLAC’s President and Chief Financial Officer, an aggregate of up to $20,000 per month for their services as executive officers and directors of MLAC, until the earlier to occur of the completion of MLAC’s initial business combination or its liquidation. As of December 31, 2025, MLAC has incurred and paid an expense of $240,000 of such fee; and

• MLAC’s officers and directors will be eligible for continued indemnification and continued coverage under a tail policy for MLAC’s directors’ and officers’ liability insurance policy for up to a six-year period from and after the Closing for events occurring prior to the Closing, which tail policy is to be paid for by Pubco at the Closing pursuant to the Business Combination Agreement. If the Business Combination does not close, MLAC’s officers and directors may not receive this tail insurance coverage.

• the anticipated election of Mr. Grinberg, MLAC’s Chairman and Chief Executive Officer, as director of Pubco after the consummation of the Business Combination. As such, in the future, such directors will receive any cash fees, stock options or stock awards that the Pubco Board determines to pay to such directors.

• in addition to the interests of the Sponsor and its Affiliates in the Business Combination, MLAC Shareholders should be aware that MLAC’s underwriter for its IPO, BTIG, may also have financial interests that are different from, or in addition to, the interests of MLAC Shareholders, including the fact that:

• pursuant to an amendment to the underwriting agreement in connection with MLAC’s IPO, BTIG may receive a deferred fee equal to $1,000,000, and such fees are payable at the closing of the Business Combination only if MLAC completes

19

the Business Combination; and pursuant to the Sponsor Support Agreement, BTIG will forfeit its 310,000 MLAC Private Placement Shares; and

• pursuant to the BTIG Financial Advisory Services Agreement, BTIG may receive reimbursement of all reasonable out-of-pocket expense as financial advisor to MLAC in connection with the Business Combination, (provided that, if the expense exceeding $100,000, BTIG shall submit to MLAC for its prior written approval), such reimbursement are payable at the closing of the Business Combination only if MLAC completes an initial business combination;

The MLAC Board reviewed and considered the potential conflicting interests described above with respect to the Sponsor and Affiliates and, after taking into account the factors they deemed applicable (including the potential conflicting interests), unanimously approved the Business Combination Agreement and the transactions contemplated therein.

For more information, see “Certain Relationships and Related Party Transactions” and see the risk factor entitled “Risk Factors — Risks Related to the Business Combination — Since the Sponsor and its Affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders, a conflict of interest may have existed in determining whether the Business Combination with Pubco and the Company is appropriate as MLAC’s initial business combination. Such interests include that the Sponsor and Affililates will lose their entire investment in MLAC if the Business Combination is not completed or any other business combination is not completed.”

Additionally, in considering the recommendation of the MLAC Board to vote in favor of approval of the Proposals, unaffiliated MLAC Shareholders should keep in mind that the directors and executive officers of Pubco have interests in such Proposals that are different from or in addition to, those of unaffiliated MLAC Shareholders. In particular:

• the Company has entered into offer letters with its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer that are expected to be assigned to Pubco at the Closing;

• Pubco intends to grant equity awards under the Incentive Plan to its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer;

• the fact that Gerald Bartholomew Smith, the Company’s Chief Executive Officer, is expected to become a director and Chief Executive Officer of Pubco at Closing; and

• the Company’s Chief Executive Officer is party to an advisory agreement with Avalanche BVI that provides for payment of certain consideration if the Closing does not occur; however, in the event that the Closing does occur, Gerald Bartholomew Smith will no longer serve as an advisor to Avalanche BVI nor receive any compensation from Avalanche BVI.

Consideration to be Received by, and Securities to be Issued to, the Sponsor and its Affiliates

Set forth below is a summary of the terms and amount of the consideration received or to be received by the Sponsor and its Affiliates in connection with the Transactions, the amount of securities issued or to be issued by Pubco to the Sponsor and its Affiliates and the price paid or to be paid or consideration provided for such securities or any related financing transaction.

Sponsor	2,800,000 MLAC Class B Ordinary Shares, of which 1,600,000 shares (the”Sponsor Earnout Shares”) shall be held in escrow and shall vest and be released from escrow, in the amounts specified below, upon Pubco meeting the milestones specified below:	$25,000 paid to purchase the 7,187,500 MLAC Class B Ordinary Shares (of which 4,387,500 shares will be forfeited upon the Closing).
	(i) Upon the occurrence of Triggering Event I, 533,333 Sponsor Earnout Shares shall be released from the escrow account to the Sponsor;
	(ii) Upon the occurrence of Triggering Event II, 533,333 Sponsor Earnout Shares shall be released from the escrow account to the Sponsor; and
	(iii) Upon the occurrence of Triggering Event III, 533,334 Sponsor Earnout Shares shall be released from the escrow account to the Sponsor.

Entity	Interest in Securities/Other Consideration to be Received	Price Paid or to be Paid or Consideration Provided
Sponsor	Additional MLAC Class A Ordinary Shares and/or cash	Amounts outstanding at the Closing under any MLAC Working Capital Loan will be repaid, at the lender’s option, in either cash or by the issuance of MLAC Class A Ordinary Shares at $10.00 per share.

Because the Sponsor acquired the 7,187,500 MLAC Class B Ordinary Shares at a nominal price, the Public Shareholders will incur substantial and immediate dilution upon the Closing of the Business Combination. See the sections titled “Summary of the Proxy Statement/Prospectus — Dilution,” “Risk Factors — Risks Related to the Business Combination — The value of the MLAC Class B Ordinary Shares following completion of the Business Combination is likely to be substantially higher than the nominal price paid for them, even if the trading price of shares of Pubco Class A Stock at such time is substantially less than $10.00 per share, which may create an economic incentive for the MLAC management team to pursue and consummate the Business Combination which differs from the Public Shareholders,” and “Risk Factors — Risks Related to the Business Combination — Public Shareholders who do not redeem their Public Shares will experience substantial and immediate dilution upon Closing of the Business Combination as a result of the MLAC Class B Ordinary Shares held by the Sponsor, since the value of the MLAC Class B Ordinary Shares is likely to be substantially higher than the nominal price paid for them, as well as a result of the issuance of the shares of Pubco Stock in the Transactions.”

The MLAC Board’s Reasons for Approval of the Transactions

The MLAC Board considered a variety of factors in connection with its evaluation of the Business Combination. In light of the complexity of those factors, the MLAC Board, as a whole, did not consider it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it took into account in reaching its decision. Individual members of the MLAC Board may have given different weight to different factors. Certain information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under “Cautionary Note Regarding Forward- Looking Statements.”

Before reaching its decision, the MLAC Board reviewed the information provided to it by its management, representatives of the Sponsor and MLAC’s legal and financial advisors. In addition, before determining that the Business Combination was in the best interests of MLAC and its shareholders, the MLAC Board reviewed various industry data, including a review of recent performance of public companies with the digital asset treasury strategies, such as MicroStrategy, as well as industry insights provided by the Investment Banks, which were included in the investor presentation for the Company Unit Subscription.

The MLAC Board determined that pursuing a potential business combination with Pubco and the Company would be an attractive opportunity for MLAC and the MLAC Shareholders, which determination was based on a number of factors including, but not limited to, the following:

• Exclusive partnership with the Foundation, which includes compelling access to AVAX. AVAT has an 18-month exclusive agreement with the Foundation on AVAX sales to any DAT company and, through its relationship with the Foundation, access to opportunities with partners, investors, builders, and service providers across the Avalanche ecosystem.

• Differences between AVAT and other DATs in the marketplace. AVAT seeks to employ an active (instead of passive) DAT strategy, combining a targeted yield strategy with ecosystem development that is designed to provide shareholders with more holistic exposure to the growth of the Avalanche ecosystem.

• Structural trends driving Avalanche utilization, including growth in stablecoin and digital money markets; as well as the tokenization of equities, private credit and other real world assets.

• Avalanche’s technological strengths, including processing speed and ease of customization.

• Attractive economics, including a discounted mNAV (calculated as the multiple of enterprise value to the market value of AVAX holdings) of approximately 0.77x at the execution of the Business Combination Agreement, assuming no redemptions from MLAC Shareholders.

• Strategic leadership on the Pubco Board and the Advisory Board, including Advisory Board members Ava Labs founder Emin Gün Sirer, managing partner of Dragonfly Haseeb Qureshi, Blockworks Inc. Chief Executive Officer Jason Yanowitz and Aave Labs Chief Executive Officer Stani Kulechov.

• Strong management team with institutional connectivity, Avalanche protocol expertise, and over 20 years of experience across digital assets, proprietary trading, asset management, market making and institutional capital markets.

• Avalanche real world use cases across finance, payments, corporate/enterprise, government, gaming, sports and entertainment, which signifies the potential for significant market acceptance and adoption. Examples include the use of Avalanche technology in JP Morgan’s Kinexys, the California DMV’s registration of 42 million vehicle titles, Apollo’s launch of tokenized portfolios, funds and private credit, and FIFA’s launch of its own blockchain for digital collectibles and enhanced fan engagement.

22

In connection with its approval of the Business Combination Agreement, the MLAC Board considered the enterprise valuations, after factoring in the Company Unit Subscription, the Foundation’s token sale, and the implied value of AVAX holdings (or mNAV). Additionally, the MLAC Board considered potential valuation multiples of other digital asset tokens such as those supported by the blockchain platforms Ethereum, Stellar, Cardano, and Solana. The MLAC Board believed that the transaction structure for the Business Combination, which features a discounted mNAV, could deliver significant returns on investment to MLAC Shareholders. The MLAC Board also considered the Company’s unique relationship with the Foundation, and its potential to provide strategic exposure to the evolving Avalanche ecosystem, which the MLAC Board believes presented a compelling opportunity for value creation for MLAC Shareholders.

In approving the Business Combination, the MLAC Board considered the potential benefits of, but ultimately determined not to obtain, a fairness opinion. The MLAC Board and MLAC’s management have extensive experience in the fintech industry, operational management and investment and financial analysis, including as part of the team’s prior involvement in the proposed acquisition of W3BCLOUD Holdings Inc, a cryptocurrency data center, by Social Leverage Acquisition Corp. I. Furthermore, members of the MLAC Board have made professional investments in the digital asset space. As such, the members of the MLAC Board and management team believe that they are qualified to conduct and analyze the due diligence required to identify a business combination partner. The independent directors of the MLAC Board did not retain an unaffiliated representative to act solely on behalf of the unaffiliated MLAC Shareholders to negotiate the terms of the Business Combination and/or prepare a report concerning the approval of the Business Combination.

In the course of its deliberations, in addition to the various other risks associated with the business of Pubco, as described in the section entitled “Risk Factors” appearing elsewhere in this proxy statement/ prospectus, the MLAC Board also considered a variety of uncertainties, risks and other potentially negative factors relevant to the Business Combination, including the following:

• AVAX and the Volatility of the Price of AVAX. The market prices of AVAX Tokens and other digital assets may fluctuate significantly, potentially due to broader cryptocurrency market movements, regulatory developments, technological changes or general economic conditions. These fluctuations could materially affect the value of Pubco’s digital assets, its mNAV, and overall financial performance.

• Macroeconomic Risks Generally. Macroeconomic uncertainty, including the potential impact of the tariffs to be instituted by the United States government, and the effects they could have on the price of AVAX and Pubco’s potential financial performance.

• Regulatory Risks with respect to AVAX. Cryptocurrency-related regulations are evolving, and future developments regarding the treatment of crypto assets for U.S. and foreign tax purposes could adversely impact Pubco’s business. AVAX and other digital assets are novel assets, and are subject to significant legal, commercial, regulatory and technical uncertainty.

• Competition in Pubco’s Industry. Many publicly listed digital asset treasury vehicles currently trade at a premium to mNAV, which has attracted and may continue to attract other companies to pursue similar digital asset treasury strategies. This increased number of companies could make it more difficult or expensive for Pubco to, among other things, pursue its strategy of raising funds through public offerings of securities to purchase more AVAX for its corporate treasury.

• Risks in Pubco’s Business Plan, which Business Plan May Not be Achieved. Pubco does not have significant operations and will not have significant operations prior to Closing. Pubco may not be successful in building its AVAX holdings or in building the ancillary AVAX related services it intends to launch in tandem with the accumulation and management of its AVAX holdings. Pubco may encounter unforeseen expenses, difficulties, complications, delays and other unknown events that may cause its costs to exceed its expectations.

• Management Team of Pubco and Public Company Readiness. Gerald Bartholomew Smith, Laine Mihalchick Moljo and Sean Ostrower, who are expected to lead Pubco management after Closing, have limited experience managing an operating a public company. There is a risk that Pubco will not be able to hire the necessary personnel to timely and accurately prepare financial statements and reports to be publicly filed the SEC, or that Pubco’s compliance infrastructure may not be able to successfully manage the increased compliance risks and internal controls requirements to which it will be subject as a public company.

23

• Valuation. The Company has no operating history and the volatile nature of the price of AVAX makes it difficult to evaluate Pubco’s future prospects. The Company’s lack of operating history also makes it difficult to accurately forecast its future results of operations, which are subject to numerous uncertainties as further described herein. In addition, MLAC did not obtain a fairness opinion (or any similar report or appraisal) in connection with the Business Combination. As a result, there is a risk that the MLAC Board may not have properly valued the Company’s business.

• Listing Risk. The challenges associated with preparing Pubco for requisite listing requirements to which it will be subject as a publicly traded company on a national stock exchange, and the potential inability of Pubco to obtain an initial listing and maintain the listing of Pubco Class A Stock on Nasdaq or any other securities exchange following the Closing.

• MLAC Shareholders Holding a Minority Position in Pubco. MLAC Shareholders will hold a minority ownership position in Pubco following completion of the Business Combination, with existing Public Shareholders owning approximately 40.5% of the issued and outstanding shares of Pubco Class A Stock after Closing, assuming no redemptions.

• Control of Pubco by the Seller. Pubco will have two classes of common stock after Closing, with Pubco Class A Stock having no voting rights (except as required by applicable law) until all shares of Pubco Class B Stock are cancelled, and Pubco Class B Stock having voting rights. At Closing, MLAC Shareholders will receive shares of Pubco Class A Stock and only the Seller will own shares of Pubco Class B Stock. As a result, Pubco will be a controlled company under Nasdaq listing standards after Closing, with all decisions of Pubco being controlled by the Seller. Accordingly, Public Shareholders will not participate in the governance of Pubco after Closing. For additional information, see the section of this proxy statement/prospectus entitled “Description of Pubco Securities.”

• Litigation. The possibility of litigation or MLAC shareholder actions challenging the Transactions or injunction against any of the actions required to be taken in order to consummate the Business Combination.

• Fees and Expenses. The fees and expenses associated with completing the Business Combination, including those payable to the Investment Banks and BTIG.

• Redemptions. The risk that a significant number of Public Shareholders may exercise their redemption rights, thereby depleting the amount of cash available in the Trust Account to fund Pubco’s business after the Business Combination, not only making it more difficult for Pubco to meet initial listing requirements, but also reducing the liquidity of the trading market for Pubco Class A Stock upon Closing.

In addition to considering the factors described above, the MLAC Board also considered that:

• Interests of Certain Persons. The Sponsor, its affiliates and certain executive officers and directors of MLAC, as individuals, may have interests in the Business Combination that are in addition to, and that may be different from (and may conflict with), the interests of MLAC Shareholders. The possibility that the MLAC Board may have been influenced by conflicts between what may be in MLAC’s best interests and what may be best for a director’s personal interests, including the possibility that if the Business Combination is not consummated, and MLAC is forced to liquidate because it is unable to consummate another business combination within the timeframe permitted by its Memorandum and Articles of Association, the Class B Ordinary Shares and Private Placement Units owned by the Sponsor would be worthless. For more information, see section entitled “The Business Combination Proposal — Interests of the Sponsor and MLAC’s Directors and Executive Officers in the Business Combination.”

• Differing Returns. The Sponsor paid $25,000, or approximately $0.005 per share, for the MLAC Founder Shares (of which it currently holds 7,187,500, 4,387,500 of which the Sponsor has agreed to surrender, immediately prior to, and subject to the consummation of, the MLAC Merger). Such shares (after accounting for the share surrender), are valued at approximately $28,924,000, based on the closing price of MLAC Class A Ordinary Shares of $10.30 on September 30, 2025, the business day before the MLAC Board approved the Business Combination. Such shares will be worthless if a business combination is not consummated. The Sponsor and its affiliates can earn a positive rate of return on their investment even if Public Shareholders experience a negative return following the consummation of the Business Combination.

24

After considering the foregoing, the MLAC Board concluded, in its business judgment, that the potential benefits to MLAC and the MLAC Shareholders relating to the Business Combination outweighed the potentially negative factors and risks relating to the Business Combination.

Recommendation to MLAC Shareholders

The MLAC Board has determined that the Business Combination Proposal and each of the other Proposals are in the best interests of MLAC and the MLAC Shareholders and unanimously recommends that MLAC Shareholders vote “FOR” the Business Combination Proposal, “FOR” the Merger Proposal, “FOR” each of the Domestication and Organizational Documents Proposals, “FOR” the Nasdaq Proposal and “FOR” the Adjournment Proposal, if presented.

For more information about the MLAC Board’s recommendation and the Proposals, see the sections titled “Extraordinary General Meeting of MLAC Shareholders — Recommendation of the MLAC Board” and “The Business Combination Proposal — The MLAC Board’s Reasons for Approval of the Transactions.”

U.S. Federal Income Tax Considerations

For a description of U.S. federal income tax consequences of the Business Combination, the exercise of redemption rights in respect of Public Shares and the ownership and disposition of shares of Pubco Class A Stock, see the section entitled “U.S. Federal Income Tax Considerations.”

Anticipated Accounting Treatment

The Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, MLAC will be treated as the “acquired” company for financial reporting purposes. This determination was primarily based on the current members of the Company having a majority of the voting power of Pubco upon the Closing, Company senior management comprising all of the senior management of Pubco, and the Company’s operations comprising the ongoing operations of Pubco. Accordingly, for accounting purposes, the Business Combination will be treated as the equivalent of the Company issuing shares for the net assets of MLAC, accompanied by a recapitalization. The net assets of MLAC will be stated at historical cost, with no goodwill or other intangible assets recorded. As a result, any transaction costs incurred to effect the recapitalization represent costs related to issuing equity and raising capital that are recognized as a reduction to the total amount of equity raised through the Company Unit Subscription Agreements rather than an expense recorded as incurred. Operations prior to the Business Combination will be those of the Company.

Emerging Growth Company

Upon consummation of the Business Combination, Pubco will be an “emerging growth company” as defined in the JOBS Act. Pubco will remain an “emerging growth company” until the earliest to occur of (i) the last day of the fiscal year (a) following the fifth anniversary of the Closing of the Business Combination, (b) in which Pubco has total annual gross revenue of at least $1.235 billion or (c) in which Pubco is deemed to be a large accelerated filer, which means the market value of shares of Pubco Stock held by non-affiliates exceeds $700 million as of the last business day of Pubco’s prior second fiscal quarter, and (ii) the date on which Pubco issued more than $1.0 billion in non-convertible debt during the prior three-year period. Pubco intends to take advantage of exemptions from various reporting requirements that are applicable to most other public companies that are classified as “emerging growth companies,” including, but not limited to, an exemption from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that Pubco’s independent registered public accounting firm provide an attestation report on the effectiveness of its internal control over financial reporting and reduced disclosure obligations regarding executive compensation.

Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period

26

and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. Pubco has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, Pubco, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of Pubco’s financial statements with certain other public companies difficult or impossible because of the potential differences in accounting standards used. See “Risk Factors — Risks Related to Being a Public Company — Pubco will be an “emerging growth company,” and it cannot be certain if the reduced SEC reporting requirements applicable to emerging growth companies will make shares of Pubco Stock less attractive to investors, which could have a material and adverse effect on Pubco, including its growth prospects.”

Controlled Company

After the consummation of the Transactions, Pubco will be a “controlled company” under the Nasdaq Rules. Under the Nasdaq rules, a controlled company may elect to utilize exemptions from certain of Nasdaq’s corporate governance requirements, including the requirements (a) that a majority of the board consists of independent directors; (b) for an annual performance evaluation of the nominating and corporate governance and compensation committees; (c) that the company has a nominating and corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities and (d) that the company has a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibility. See “Risk Factor — Risks Related to Ownership of Pubco Stock Following the Business Combination — Pubco is a “controlled company” within the meaning of the Nasdaq Rules, and, as a result, will qualify for, and rely on, exemptions from certain corporate governance requirements. Our shareholders do not have the same protections afforded to shareholders of companies that are subject to such requirements.”

Regulatory Matters

The Business Combination and the transactions contemplated by the Business Combination Agreement are not subject to any additional federal or state regulatory requirement or approval, except for (i) filings with the Registrar of Companies of the Cayman Islands necessary to effectuate the Domestication, which will be filed on behalf of MLAC with the Registrar of Companies of the Cayman Islands and (ii) filings with the Secretary of State of the State of Delaware (“Delaware Secretary of State”) necessary to effectuate the MLAC Merger and Company Merger, which will be filed on behalf of MLAC, the Company, Company Merger Sub and MLAC Merger Sub with the Delaware Secretary of State upon the approval of the Business Combination Proposal and satisfaction of all other conditions not waived by the applicable parties under the Business Combination Agreement.

Conditions to Closing of the Business Combination

Under the Business Combination Agreement, the obligations of the parties to consummate (or cause the consummation of) the Transactions are subject to the satisfaction or waiver (where permissible) of a number of conditions:

Mutual Conditions to Obligations of All Parties (subject to written waiver by Seller and MLAC, solely with respect to the final condition listed below):

• the receipt of the Required Shareholder Approval from MLAC Shareholders;

• the consummation of the Transactions not being prohibited by applicable law;

• the effectiveness of the Registration Statement; and

• the shares of Pubco Class A Stock having been approved for listing on Nasdaq, the NYSE or another national securities exchange reasonably accepted by Pubco, MLAC and the Seller.

Conditions to Obligations of the Company, Pubco, Pubco Subsidiaries and Seller (subject to written waiver by Seller):

• the representations and warranties of MLAC being true and correct, subject to the applicable materiality standards contained in the Business Combination Agreement;

27

• material compliance by MLAC with its applicable pre-closing covenants;

• no occurrence of a Material Adverse Effect with respect to MLAC since the date of the Business Combination Agreement which is continuing and uncured; and

• the Sponsor having performed in all material respects its obligations required under the Sponsor Support Agreement.

Conditions to Obligations of MLAC (subject to written waiver by MLAC):

• the representations and warranties of the Company, Pubco, Pubco Subsidiaries, the Seller Related Parties, and Astral being true and correct, subject to the applicable materiality standards contained in the Business Combination Agreement;

• material compliance by the Company, Pubco, Pubco Subsidiaries, the Seller Related Parties and Astral with their respective pre-closing covenants;

• no occurrence of a Material Adverse Effect with respect to the Company or Pubco; and

• completion of the Dragonfly Contribution and the Foundation Transaction.

Pursuant to the Business Combination Agreement, “Material Adverse Effect” with respect to any specified person is any fact, event, occurrence, change, or effect that has had, or would reasonably be expected to have, individually or in the aggregate, a material adverse effect on (i) the business, assets, liabilities, results of operations or condition (financial or otherwise) of such party and its subsidiaries, taken as a whole, or (ii) the ability of such person or any of its subsidiaries to consummate the transactions contemplated by the Business Combination Agreement or the Ancillary Documents to which it is a party or bound to perform its obligations under such documents, provided, however, that with respect to point (i), the following changes or effects (by themselves or when aggregated with others) are not considered a Material Adverse Effect:

(a) general changes in financial or securities markets (including interest rates) or general economic or political conditions in the country or region where the party or its subsidiaries do business;

(b) changes, conditions, or effects that generally affect the industries or markets in which the party or its subsidiaries principally operate;

(c) changes in the price or trading volume of AVAX (provided that the underlying cause of any such event, occurrence, change or effect in the price or trading volume may be considered in determining whether a Material Adverse Effect has occurred or would reasonably be expected to occur to the extent not excluded by another exception);

(d) any proposal, enactment, or change in interpretation of, or any other change in, applicable laws, IFRS, GAAP or other applicable accounting principles or mandatory changes in the regulatory accounting requirements applicable to any industry in which such party and its subsidiaries principally operate;

(e) conditions caused by acts of God, natural disasters, terrorism, war (whether or not declared), escalation of hostilities, geopolitical conditions, local, national or international political conditions or any outbreak or continuation of an epidemic or pandemic or the effects of governmental actions or Laws in response to them;

(f) the taking of any action required by the Business Combination Agreement or any Ancillary Agreement; and

(g) any failure by the party and its subsidiaries to meet internal or published budgets, projections, forecasts, or predictions of financial performance for any period (provided that the underlying cause of any such failure may be considered in determining whether a Material Adverse Effect has occurred or would reasonably be expected to occur to the extent not excluded by another exception).

The exceptions in letters (a), (b), (c), (d), (e) and (g) above will be taken into account in determining whether a Material Adverse Effect has occurred or could reasonably be expected to occur to the extent that such event, occurrence, fact, condition or change has a

28

disproportionate and adverse effect on such party or any of its subsidiaries compared to similarly situated participants in the industries in which such party or any of its subsidiaries primarily conducts its businesses.

Notwithstanding the foregoing, for MLAC, the number of MLAC Ordinary Shares redeemed in connection with the Business Combination or the failure to obtain the Required Shareholder Approval shall not, in and of itself, be deemed a Material Adverse Effect on or with respect to MLAC, provided that the underlying causes of any such redemptions or failure to obtain the Required Shareholder Approval may be considered if not otherwise excluded by another exception and provided, further, with respect to the failure to obtain the Required Shareholder Approval, that MLAC has not violated its obligations under this Agreement in connection with obtaining such Required Shareholder Approval.

Exclusivity

During the Interim Period, the parties agreed not to solicit, encourage or engage in discussions regarding any Acquisition Proposal or Alternative Transaction outside the transactions contemplated by the Business Combination Agreement. The parties also agreed not to provide non-public information or enter into any agreements related to such proposals. If any party receives an Acquisition Proposal, such party is expected to promptly notify the other parties and keep them informed of any developments.

Representations and Warranties

The Business Combination Agreement contains customary representations and warranties of the Parties, which will not survive the Closing. Certain representations and warranties are qualified by materiality or Material Adverse Effect.

Risk Factors

In evaluating the proposals to be presented at the Meeting, MLAC Shareholders should carefully read this proxy statement/prospectus and especially consider the factors discussed in the section entitled “Risk Factors.” These risks are summarized below.

Risks Related to the Business and Strategy of Pubco

• The Company has no operating history and has not yet produced any revenues, which make it difficult to evaluate Pubco’s business and future prospects, and Pubco may not be able to achieve or maintain profitability in any given period.

• Pubco may not be able to successfully execute its business strategies.

• Pubco may seek to grow our business through minority investments, joint ventures and acquisitions, which could divert management’s attention and otherwise disrupt operations and harm our operating results. Pubco may fail to acquire or invest in companies whose market power or technology could be important to the future success of the business.

• Pubco’s operating results, revenues and expenses may significantly fluctuate, including due to the highly volatile nature of AVAX, which has had and could have in the future, an adverse effect on the market price of Pubco Class A Stock.

• Our AVAX acquisition strategy exposes us to various risks associated with AVAX.

• A significant decrease in the market value of our AVAX holdings could adversely affect our ability to satisfy our financial obligations.

• Pubco will operate in a highly competitive environment and will compete against companies and other entities with similar strategies, including companies with significant AVAX holdings and ETFs and ETPs for AVAX and other digital assets, and Pubco’s business, operating results and financial condition may be adversely affected if Pubco is unable to compete effectively.

• Pubco may suffer losses due to abrupt and erratic market movements.

• The emergence or growth of other digital assets, including those with significant private or public sector backing, including by governments, consortiums or financial institutions, could have a negative impact on the price of AVAX and adversely affect Pubco’s business.

• Pubco’s AVAX holdings will be less liquid than its cash and cash equivalents and may not be able to serve as a source of liquidity for Pubco.

• The Avalanche Network and its native digital asset, AVAX, is a relatively new technological innovation with a limited operating history.

• AVAX is created and transmitted through the operations of the peer-to-peer Avalanche Network, a decentralized network of computers running software following the Avalanche protocol. If the Avalanche Network is disrupted or encounters any unanticipated difficulties, the value of AVAX could be negatively impacted.

• Pubco will face risks associated with AVAX delegation, staking, liquid staking and associated lock-ups.

• Pubco will face risks relating to the custody of its AVAX, including the loss or destruction of private keys required to access our AVAX and cyberattacks or other data loss relating to our AVAX. If Pubco or its third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to Pubco’s AVAX, if Pubco’s private keys are lost or destroyed, or other similar circumstances or events occur, including the ability to reverse engineer private keys, Pubco may lose some or all of its AVAX and Pubco’s financial condition and results of operations could be materially adversely affected.

30

• Our limited insurance protection exposes us and our shareholders to the risk of loss of our AVAX for which no person is liable.

• The accounting treatment of our AVAX holdings are likely to have significant accounting impacts, including volatility of our results. If financial accounting standards undergo significant changes, our operating results could fluctuate.

• AVAX and other digital assets are novel assets, which will expose Pubco to significant legal, commercial, regulatory and technical uncertainty, which could materially adversely affect Pubco’s financial position, operations and prospects.

• The regulatory environment for digital assets in the United States and globally remains highly uncertain and is evolving rapidly. U.S. policymakers are only beginning to define a comprehensive regulatory framework for digital assets. As a result, Pubco may face challenges in adapting to proposed or newly enacted laws and regulations, which could materially and adversely affect its business, financial condition and operations.

• AVAX’s status as a product that may be offered and sold as a “security” in any relevant jurisdiction, as well as the status of Avalanche-related products, and services in general, is subject to uncertainty, and if Pubco is unable to properly characterize such product or service offering, Pubco may be subject to regulatory scrutiny, inquiries, investigations, fines and other penalties, which may adversely affect Pubco’s business, operating results and financial condition.

• Regulatory changes classifying AVAX as a “security” could lead to Pubco’s classification as an “investment company” under the Investment Company Act and could adversely affect the market price of AVAX and the market price of shares of Pubco Class A Stock.

• Pubco will not be subject to the same legal and regulatory obligations, including certain compliance and reporting obligations intended to protect investors, that apply to investment companies such as mutual funds and ETFs, or to obligations applicable to investment advisers.

• Pubco is subject to laws, regulations and executive orders regarding economic and trade sanctions, anti- bribery, AML, and counter-terrorism financing that could impair its ability to compete in international markets or subject Pubco to criminal or civil liability if violated. As Pubco continues to expand and localize its international activities, its obligations to comply with the laws, rules, regulations and policies of a variety of jurisdictions will increase and Pubco may be subject to investigations and enforcement actions by U.S. and non-U.S. regulators and governmental authorities.

• Due to the unregulated nature and lack of transparency surrounding the operations of many AVAX trading venues, AVAX trading venues may experience greater fraud, security failures or regulatory or operational problems than trading venues for more established asset classes, which may result in a loss of confidence in AVAX trading venues and adversely affect the value of Pubco’s AVAX holdings.

• Pubco’s compliance and risk management methods might not be effective and may result in outcomes that could adversely affect Pubco’s reputation, operating results and financial condition.

• In the ordinary course of business managing its AVAX holding as an AVAX treasury company, Pubco may purchase AVAX through spot markets which may be exposed to fraud and market manipulation, including through front running and wash trading, which may adversely affect the value of the shares of Pubco Class A Stock.

• If the digital asset award or transaction fees for recording transactions on the Avalanche Network are not sufficiently high to incentivize validators, such validators may demand high transaction fees, which could negatively impact the value of AVAX and the value of the Pubco Class A Stock.

• Although Pubco will have relevant due diligence procedures at Closing regarding anti-money laundering (“AML”) and know-your-customer (“KYC”), these procedures may fail to prevent illegal transactions, which could subject Pubco to criminal and civil liabilities and impact the value of the shares of Pubco Class A Stock.

31

Risks Related to Being a Public Company

• The market price of Pubco Class A Stock may be volatile and decline materially as a result of volatility in AVAX or the digital asset markets generally, or for other reasons. You should be aware that you may lose some or all of your investment.

• A substantial part of Pubco’s assets following the Business Combination will be its AVAX holdings and cash and cash equivalents from the proceeds of the Business Combination and the Company Unit Subscription not invested in AVAX. Although Pubco is expected to have certain other operations, Pubco will depend on such retained cash and cash equivalents to pay its ongoing obligations.

• Pubco’s ability to timely raise capital in the future may be limited, or may be unavailable on acceptable terms, if at all. Pubco’s failure to raise capital when needed could harm its business, operating results and financial condition.

• The issuance of additional shares or convertible securities by Pubco could make it difficult for another company to acquire Pubco, may dilute the ownership of Pubco shareholders and could adversely affect the price of Pubco Class A Stock.

• Future resales of Pubco Class A Stock after the consummation of the Business Combination may cause the market price of Pubco’s securities to drop significantly, even if Pubco’s business is doing well.

• Pubco will incur significant costs post-Business Combination as a result of being a public company, including additional legal, accounting, insurance and other expenses, as well as costs associated with public company reporting requirements.

• Pubco’s management team is expected to have limited experience managing and operating a U.S. public company.

• If Pubco is unable to maintain an effective system of internal controls and compliances, its business and reputation could be adversely affected.

• Pubco’s failure to timely and effectively implement controls and procedures required by Section 404(a) of the Sarbanes-Oxley Act that will be applicable to it following consummation of the Business Combination could have a material adverse effect on its business, financial condition, results of operations, cash flow and prospects.

• Pubco will be an “emerging growth company” as defined in the JOBS Act and may be exempt from certain corporate governance requirements thereunder. The reduced public company reporting requirements applicable to emerging growth companies may make Pubco Class A Stock less attractive to investors.

• If securities or industry analysts do not publish research or reports about Pubco’s business or publish negative reports, the market price of Pubco Class A Stock could decline.

• Pubco may be subject to material litigation, including individual and class action lawsuits, as well as investigations and enforcement actions by regulators and governmental authorities. These matters are often expensive and time consuming, and, if resolved adversely, could harm Pubco’s business, financial condition and operating results.

• Since members of the Advisory Board have interests that are different from, or in addition to (and which may conflict with) the interests of Pubco, a conflict of interest may arise in connection with their Advisory Board services.

• We have identified a material weakness in our internal control over financial reporting. If remediation of this material weakness is not effective, if we experience additional material weaknesses, or if we otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations.

Risks Related to the Business Combination

• The market price of shares of Pubco Class A Stock after the Business Combination will be affected by factors different from those currently affecting the market price of MLAC Class A Ordinary Shares.

32

• The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisfied or waived, the Business Combination Agreement may be terminated in accordance with its terms and the Business Combination may not be completed.

• The Business Combination Agreement contains provisions that limit MLAC from seeking an alternative business combination. If the Business Combination is not completed, those restrictions may make it harder for MLAC to complete an alternate business combination before the end of the Combination Period.

• The trading price of shares of Pubco Class A Stock after Closing are likely to be highly correlated to the price of AVAX, which is volatile and can rise and fall rapidly, and there is no guarantee that the price of AVAX after Closing will be greater than the Applicable Signing AVAX Price or the trading price of shares of Pubco Class A Stock would be higher than the redemption price that Public Shareholders would have received if they redeemed their Public Shares.

• The value of the MLAC Class B Ordinary Shares following completion of the Business Combination is likely to be substantially higher than the nominal price paid for them, even if the trading price of shares of Pubco Class A Stock at such time is substantially less than $10.00 per share, which may create an economic incentive for the MLAC management team to pursue and consummate the Business Combination which differs from the Public Shareholders.

• The “net cash” per Public Share not being redeemed will be less than the redemption price.

• Public Shareholders who do not redeem their Public Shares will experience substantial and immediate dilution upon Closing of the Business Combination as a result of the MLAC Class B Ordinary Shares held by the Sponsor, since the value of the MLAC Class B Ordinary Shares is likely to be substantially higher than the nominal price paid for them, as well as a result of the issuance of the shares of Pubco Stock in the Business Combination and as a result of the conversion of the Company Units.

• If Public Shareholders who wish to exercise their redemption rights in connection with the Business Combination fail to properly demand such redemption rights, they will not be entitled to convert their Public Shares into a pro rata portion of the Trust Account and will instead become stockholders of Pubco.

• Public Shareholders will not have any rights or interests in funds from the Trust Account except under certain limited circumstances, which includes in connection with the consummation of the Business Combination. Therefore, for a Public Shareholder to liquidate their investment in MLAC prior to such times, a Public Shareholder may be forced to sell their Public Shares in the open market, potentially at a loss.

• The ability of Public Shareholders to exercise redemption rights with respect to a large number of MLAC Class A Ordinary Shares may reduce proceeds available to Pubco after Closing, reduce the public “float” of shares of Pubco Class A Stock after Closing, reduce the liquidity of the trading market for the shares of Pubco Class A Stock after Closing, or make it difficult to obtain or maintain the quotation, listing or trading shares of Pubco Class A Stock on Nasdaq or another national securities exchange, and consequently may not allow the parties to complete the Business Combination, or optimize Pubco’s capital structure following the Business Combination.

• The MLAC Articles do not provide a specified maximum redemption threshold, however $1.0 million representing the underwriting fee must be paid from the funds on deposit in the Trust Account pursuant to the Amended Underwriting Agreement. The absence of a redemption threshold, other than the threshold set by the $1.0 million payable pursuant to the Amended Underwriting Agreement, may increase the risk of being subject to the “penny stock” rules or the risk that MLAC or Pubco’s securities may be delisted from Nasdaq.

• Since the Sponsor and its Affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders, a conflict of interest may have existed in determining whether the Business Combination with Pubco and the Company is appropriate as MLAC’s initial business combination. Such interests include that the Sponsor will lose its entire investment in MLAC if the Business Combination is not completed or any other business combination is not completed.

• Neither the MLAC Board nor any committee thereof obtained a fairness opinion (or any similar report or appraisal) in determining whether or not to pursue the Business Combination. Consequently, MLAC Shareholders have no assurance from

33

an independent source that the number of shares of Pubco Stock to be issued to Seller and MLAC Shareholders in the Business Combination is fair to MLAC — and, by extension, MLAC Shareholders — from a financial point of view.

• The parties to the Business Combination Agreement may waive one or more of the conditions to the Business Combination or certain of the other transactions contemplated by the Business Combination Agreement.

• MLAC’s directors and officers will have discretion on whether to agree to changes or waivers in the terms of the Business Combination Agreement, and their interests in exercising that discretion may conflict with those of the MLAC Shareholders.

• MLAC Shareholders who are not affiliated with the Sponsor may be exposed to greater risk as a result of becoming shareholders of Pubco through the Business Combination rather than acquiring shares of Pubco Class A Stock directly in an underwritten public offering as a result of the differences between the two transaction structures, including that the Business Combination did not involve an independent due diligence review by an underwriter and that the Sponsor has conflicts of interest in connection with the Business Combination.

• If MLAC is deemed to be an investment company under the Investment Company Act, MLAC may be required to institute burdensome compliance requirements and its activities may be restricted, which may make it difficult for MLAC to complete the Business Combination.

• Changes in laws or regulations (including the adoption of policies by governing administrations), or a failure to comply with any laws and regulations, may adversely affect MLAC’s business, including MLAC’s ability to complete the Business Combination.

• If the Business Combination is not approved and MLAC does not consummate another initial business combination by the end of the Combination Period, then the Sponsor’s MLAC Ordinary Shares will become worthless and the expenses it has incurred will not be reimbursed. These interests may have influenced its decision to approve the Business Combination.

• If third parties bring claims against MLAC, the proceeds held in the Trust Account could be reduced and the per-share redemption amount received by Public Shareholders could be less than $10.05 per share (based on the Trust Account balance as of October 31, 2025, and inclusive of interest earned on the funds held in the Trust Account but less taxes payable).

• MLAC Shareholders may be held liable for claims by third parties against MLAC to the extent of distributions received by them.

• MLAC’s directors may decide not to enforce the indemnification obligations of the Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to the Public Shareholders.

• MLAC may not have sufficient funds to satisfy indemnification claims of its directors and officers.

• Following the Business Combination, Pubco’s business activities may be subject to review or approval by regulatory authorities pursuant to certain U.S. or foreign laws or regulations.

• The Sponsor and its Affiliates have entered into letter agreements with MLAC, and the Sponsor has entered into the Sponsor Support Agreement with MLAC and Pubco, in each case, which requires them to vote in favor of the Business Combination, regardless of how the Public Shareholders vote.

• Because MLAC is seeking to obtain shareholder approval of the Business Combination, the Sponsor and its Affiliates may elect to purchase Public Shares from Public Shareholders, subject to any limitations under Rule 14e-5 under the Exchange Act, which may influence the vote on the Business Combination and reduce the public “float” of MLAC Class A Ordinary Shares.

• MLAC, the Company and Seller will incur transaction costs in connection with the Business Combination.

34

Risks Related to Ownership of Pubco Stock Following the Business Combination

• Seller, whose interests may conflict with yours, can individually exercise significant influence over Pubco. You will have no voting rights of Pubco Class A Stock except as required by the DGCL and the concentrated ownership of Pubco Stock may prevent you and other shareholders from influencing significant decisions in the very limited circumstances in which the DGCL will give you the right to vote and may prevent or discourage unsolicited acquisition proposals or offers for Pubco Stock, and that may adversely affect the trading price of Pubco Class A Stock.

• Seller, through its voting control of Pubco, is in a position to control actions that require shareholder approval and may make decisions that are adverse to other shareholders.

• Securities of companies formed through mergers with SPACs such as Pubco may experience a material decline in price relative to the share price of the SPACs prior to such merger.

• Volatility in Pubco’s share price could subject Pubco to securities class action litigation.

• Since the completion of the MLAC IPO, there has been a precipitous drop in the market values of companies formed through mergers involving SPACs. Accordingly, securities of companies such as Pubco may be more volatile than other securities and may involve special risks.

• Currently, there is no public market for the shares of Pubco Class A Stock. Public Shareholders cannot be sure about whether the shares of Pubco Class A Stock will develop an active trading market or whether Pubco is able to maintain the listing of Pubco Class A Stock in the future even if Pubco is successful in listing Pubco Class A Stock on Nasdaq or any other national securities exchange, which could limit investors’ ability to make transactions in shares of Pubco Class A Stock and subject Pubco to additional trading restrictions.

• Reports published by analysts, including projections in those reports that differ from Pubco’s actual results, could adversely affect the price and trading volume of Pubco Stock.

• Pubco may or may not pay cash dividends in the foreseeable future.

• Pubco is a “controlled company” within the meaning of the Nasdaq Rules, and, as a result, will qualify for, and rely on, exemptions from certain corporate governance requirements. Our shareholders do not have the same protections afforded to shareholders of companies that are subject to such requirements.

• The Amended and Restated Pubco Charter designates a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between us and our stockholders, and also provides that the federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, each of which may limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers, stockholders or employees.

• Because Pubco Class A Stock is non-voting, we and our stockholders are exempt from certain provisions of U.S. securities laws. This may limit the information available to holders of Pubco Class A Stock.

Risks Related to Taxation

• Unrealized fair value gains on our AVAX holdings could cause us to become subject to the corporate alternative minimum tax under the Inflation Reduction Act of 2022.

• Pubco’s independent registered public accounting firm’s report for the year ended December 31, 2025, contains an explanatory paragraph that expresses substantial doubt about its ability to continue as a “going concern.”

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The unaudited pro forma condensed combined financial statements do not necessarily reflect what the combined company’s financial condition or results of operations would have been had the Business Combination occurred on the dates indicated. The unaudited pro forma condensed combined financial statements also may not be useful in predicting the future financial condition and results of operations of the combined company. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors. The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only.

The historical financial statements of Pubco have been prepared in accordance with U.S. GAAP and in its functional and presentation currency of the United States dollar. The historical financial statements of AVAT have been prepared in accordance with U.S. GAAP and in its functional and presentation currency of USD. The historical financial statements of MLAC have been prepared in accordance with U.S. GAAP in its functional and presentation currency of USD.

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption of Public Shares into cash:

• Assuming No Redemptions: This presentation assumes that no Public Shareholders exercise redemption rights with respect to their Public Shares upon consummation of the Business Combination.

• Assuming Maximum Redemptions: This presentation assumes that Public Shareholders holding 22,905,484 Public Shares exercise their redemption rights for $242.3 million in the aggregate upon consummation of the Business Combination at a redemption price of approximately $10.58 per share as of March 31, 2026. The Maximum Redemptions scenario reflects the maximum number of Public Shares that can be redeemed while maintaining the requirement that the $1.0 million underwriting fee is paid from the funds on deposit in the Trust Account pursuant to the Amended Underwriting Agreement and includes all adjustments contained in the “No Redemptions” scenario and presents additional adjustments to reflect the effect of the Maximum Redemptions scenario.

The following tables set out the Class A and Class B share ownership of Pubco on a pro forma basis assuming the No Redemptions scenario and the Maximum Redemptions scenario:

RISK FACTORS

The following risk factors may have a material adverse effect on the business, financial condition and results of operations of Pubco, the Company and MLAC following the completion of the Business Combination. These risk factors are not exhaustive and investors are encouraged to perform their own investigation with respect to the business, prospects, financial condition and operating results of Pubco’s business, prospects, financial condition and operating results following the completion of the Business Combination. You should carefully consider the following risk factors in addition to the other information included or incorporated by reference in this proxy statement/prospectus, including matters addressed in the section entitled “Cautionary Note Regarding Forward-Looking Statements,” before deciding how to vote your MLAC Ordinary Shares. Please see the section entitled “Where You Can Find More Information” in this proxy statement/prospectus. Pubco, the Company and MLAC may face additional risks and uncertainties that are not presently known to them or that they currently deem immaterial, which may also impair Pubco’s business, prospects, financial condition or operating results. The following discussion should be read in conjunction with the financial statements of the Company and the financial statements of MLAC and notes thereto included elsewhere in this proxy statement/ prospectus. Throughout this section, unless otherwise indicated or the context otherwise requires, references to “we,” “us,” “our,” and other similar terms refer to Pubco prior to and/or after giving effect to the Business Combination.

Risks Related to the Business and Strategy of Pubco

The Company has no operating history and has not yet produced any revenues, which make it difficult to evaluate Pubco’s business and future prospects, and Pubco may not be able to achieve or maintain profitability in any given period.

The Company was formed as a Delaware limited liability company on August 20, 2025. The Company has no operating history and the volatile nature of the price of AVAX, which will constitute a substantial part of our assets, make it difficult to evaluate our future prospects. The Company’s lack of operating history will also make it difficult to accurately forecast the future results of operations, which is subject to a number of uncertainties including Pubco’s ability to grow the value of its AVAX holdings, develop and implement its Avalanche-focused infrastructure and the market size and growth opportunities in each of Pubco’s anticipated lines of business.

Pubco’s initial business strategy depends on, among other factors, its ability to raise capital to continue to acquire additional AVAX, to secure participation and contribution from AVAX holders through in-kind investments and to successfully apply financial trading strategies and risk-management techniques in its active management of its AVAX holdings. Pubco cannot guarantee its ability to raise additional capital, or to raise additional capital on favorable terms, which may adversely impact our business. See “Pubco’s ability to timely raise capital in the future may be limited, or may be unavailable on acceptable terms, if at all. Pubco’s failure to raise capital when needed could harm its business, operating results and financial condition.”

Pubco’s ability to generate cash flow initially will largely be dependent on the above-mentioned factors, among others. Pubco’s business strategy may not be realized as quickly as hoped, or even at all. Further, even if Pubco achieves growth, in future periods that growth could slow or decline for a number of reasons, including, but not limited to, AVAX volatility, increased competition, digital coins that compete with and may result in a decline in utilization of AVAX or replace AVAX, government regulation or Pubco’s failure, for any reason, to continue to take advantage of growth opportunities, our inability to develop, improve or effectively scale AVAX acquisition, or our inability to develop or enter into partnerships for Avalanche- related infrastructure or effectively provide related services and attract and retain relevant clientele.

Avalanche market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. There is no assurance that any estimates driving AVAX acquisition strategies will accurately reflect any particular level of revenue or growth prospects for Pubco.

Pubco will encounter risks and difficulties as described in this section. If Pubco does not manage these risks successfully, our business may be adversely impacted. If Pubco’s assumptions regarding these risks and uncertainties and its future growth are incorrect or change adversely, or if Pubco does not address these risks successfully, Pubco’s operating and financial results could differ materially from its expectations, and its business could suffer. If our revenue growth rate, when Pubco is at a revenue generation stage, were to decline significantly or become negative, it could adversely affect our operating results and financial condition. If Pubco is not able to achieve or maintain positive cash flow from operations, or if the price of AVAX declines significantly, our business may be

40

adversely impacted and Pubco may require additional financing, which may not be available on favorable terms or at all, may restrict the distribution of dividends or other payments to shareholders, or may be dilutive to our shareholders.

Pubco may not be able to successfully execute its business strategies.

A significant part of Pubco’s strategy is AVAX acquisition and securing in-kind AVAX investments, however:

• Pubco’s treasury strategy is susceptible to various risks associated with AVAX, including volatility;

• Pubco may compete with others to acquire AVAX or secure in-kind AVAX investments, and as competition increases, decreased availability or increased prices for acquisition could result;

• Pubco may experience difficulty in anticipating the timing and availability of AVAX acquisition;

• Pubco may experience difficulty in securing participation and contribution from AVAX holders through in-kind investments;

• Pubco may not be able to obtain further financing to fund any of our potential AVAX acquisitions or secure further AVAX contributions, on favorable terms or at all; and

• Pubco may not be able to generate the cash necessary to execute our AVAX acquisition strategy.

The occurrence of any of these factors could adversely affect Pubco’s AVAX acquisition strategy.

Pubco also may develop or enter into partnerships for end-to-end Avalanche-related financial and technology infrastructure, which is subject to significant risks. See “Pubco may develop or enter into partnerships for end-to-end financial and technology infrastructure. Pubco has not previously engaged in this business line, and growing these operations could be difficult, including, without limitation, due to operational challenges and significant competition.”

Pubco may seek to grow its business through minority investments, joint ventures and acquisitions, which could divert management’s attention and otherwise disrupt operations and harm operating results. Pubco may fail to acquire or invest in companies whose market power or technology could be important to the future success of its business.

In the future, Pubco may seek to grow its business through minority investments, joint ventures and acquisitions where Pubco believes such transactions have the potential to accelerate the expansion of its capabilities and AVAX accumulation. Pursuit of future potential acquisitions or investments may divert the attention of management and cause us to incur various expenses in identifying, investigating, and pursuing suitable opportunities, whether or not they are consummated. In addition, Pubco has limited experience acquiring and integrating other businesses. Pubco may be unsuccessful in integrating our acquired businesses or any additional business it may acquire in the future, and Pubco may fail to acquire companies whose market power or technology could be important to the future success of its business.

Although Pubco plans that any such initiatives will be undertaken prudently within our governance and risk frameworks and will remain subject to customary conditions, including market conditions, availability of financing and liquidity, valuation, counterparty and regulatory due diligence and required approvals, Pubco may not achieve the anticipated benefits from any acquisition or investment due to a number of factors, including but not limited to:

• unanticipated costs or liabilities associated with the acquisition or investment;

• inability to effectively integrate the assets or operations related to such acquisitions;

• inability to achieve anticipated synergies from joint ventures;

• diversion of management’s attention from other business concerns;

• regulatory uncertainties;

41

• harm to our existing business relationships with business partners and advertisers as a result of joint ventures;

• use of resources that are needed in other parts of our business; and

• use of substantial portions of our available cash to consummate the acquisition, investment or joint venture.

In addition, although Pubco has no current acquisition target or planned investment or joint venture opportunity, if appropriate opportunities arise, Pubco may acquire or invest in additional assets, products, technologies, or businesses or enter into joint ventures with such businesses that are complementary to its existing operations. Such initiatives could result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect Pubco’s operating results. In addition, if a business Pubco acquires, invests in or enters into a joint venture with fails to meet expectations, Pubco’s business, operating results, and financial condition may suffer.

Pubco’s operating results, revenues and expenses may significantly fluctuate, including due to the highly volatile nature of AVAX, which has had and could have in the future an adverse effect on the market price of Pubco Class A Stock.

Our operating results will be dependent on the broader Avalanche ecosystem. Due to the rapidly evolving nature of digital assets and the volatile price of AVAX, which has experienced and continues to experience significant volatility, Pubco expects that its operating results will fluctuate significantly from quarter to quarter in accordance with market sentiments and movements in the broader Avalanche ecosystem. Pubco expects that its operating results will fluctuate significantly as a result of a variety of factors, many of which are unpredictable and in certain instances are outside of its control, including:

• fluctuations in the price of AVAX, of which Pubco will have significant holdings, and in which Pubco may continue to make significant purchases and announcements about its transactions in AVAX;

• regulatory, commercial and technical developments related to AVAX or Avalanche;

• investor perception of Pubco, including as compared to investment vehicles that are or will be designed to track the price of AVAX, such as spot AVAX ETPs;

• changes in the legislative or regulatory environment or actions by U.S. or non-U.S. governments or regulators, including fines, orders or consent decrees;

• regulatory changes or scrutiny that impact our ability to offer certain products or services;

• pricing for or temporary suspensions of products and services Pubco expects to offer in the future in accordance with our strategy;

• investments Pubco may make in the development of products and services, and sales and marketing;

• market conditions of, and overall sentiment towards, Avalanche and AVAX, including negative publicity, media or social media coverage, or sentiment due to events in or relating to, or perception of, Avalanche or the broader digital assets industry, for example: (i) public perception that AVAX can be used as a vehicle to circumvent sanctions, including sanctions imposed on Russia or certain regions related to the ongoing conflict between Russia and Ukraine, or to fund criminal or terrorist activities, such as the purported use of digital assets by Hamas to fund its terrorist attack against Israel in October 2023; (ii) previous, pending, or expected civil, criminal, regulatory enforcement or other high profile actions against major participants in the digital assets industry, including the SEC’s dismissed enforcement actions against Coinbase, Inc., Payward Ventures, and Binance Holdings Ltd.; (iii) additional filings for bankruptcy protection or bankruptcy proceedings of major digital asset industry participants, such as the bankruptcy proceeding of FTX Trading Ltd. and its affiliates;

• the fact that AVAX holdings may come to be concentrated among AVAX treasuries; the possibility that other persons or entities control multiple wallets that collectively hold a significant number of AVAX, even if they individually only hold a small amount; concentrated AVAX holdings may permit large holders of AVAX, alone or in coordination, to manipulate the price of AVAX by restricting or expanding the supply of AVAX; or the market price of AVAX may be susceptible to large

42

sales or distribution by such holders, whether purposeful or forced as a result of such holders becoming illiquid; and the concentration of AVAX holdings, and susceptibility to such holders, may also erode investor confidence in AVAX and investment strategies of AVAX treasuries;

• investment and trading activities, such as (i) trading activities of highly active retail and institutional users, speculators, validators and investors; (ii) actual or expected significant dispositions of AVAX by large holders, including the expected liquidation of digital assets associated with entities that have filed for bankruptcy protection, such as FTX Trading Ltd., which in late 2023 and early 2024 sold several billion dollars worth of digital assets, and the transfer and sale of AVAX associated with significant hacks, seizures or forfeitures, such as the DeltaPrime hack in November 2024 when an attacker exploited a smart contract flaw, draining approximately $4.8 million worth of digital assets including AVAX and (iii) actual or perceived manipulation of the spot or derivative markets for AVAX or AVAX ETPs;

• macroeconomic conditions, including interest rates, inflation and central banking policies;

• regulatory, legislative, enforcement and judicial actions that adversely affect the price, ownership, transferability, trading volumes, legality or public perception of Avalanche, or that adversely affect the operations of or otherwise prevent digital asset custodians, trading venues, lending platforms or other digital assets industry participants from operating in a manner that allows them to continue to deliver services to the digital assets industry;

• the development and introduction of existing and new products and services by our competitors;

• competition from other digital assets that exhibit better speed, security, scalability or energy efficiency, that feature other more favored characteristics, that are backed by governments, including the U.S. government, or reserves of fiat currencies, or that represent ownership or security interests in physical assets;

• a decrease in the price of other digital assets, including stablecoins, or the crash or unavailability of stablecoins that are used as a medium of exchange for AVAX purchase and sale transactions, such as the temporary or total loss of value of the stablecoins Terra USD, USDT and USDC in recent years, including to the extent the decrease in the price of such other digital assets or the unavailability of such stablecoins may cause a decrease in the price of AVAX or adversely affect investor confidence in digital assets generally;

• disruptions, failures, unavailability or interruptions in service of trading venues for AVAX, such as, for example, the announcement by the digital asset exchange FTX Trading Ltd. that it would freeze withdrawals and transfers from its accounts and subsequent filing for bankruptcy protection and the SEC enforcement action brought against Binance Holdings Ltd., which initially sought to freeze all of its assets during the pendency of the enforcement action and has since resulted in Binance Holdings Ltd. discontinuing all fiat deposits and withdrawals in the U.S.;

• the development and introduction of new products and services by us;

• our ability to control costs, including our operating expenses incurred to grow and expand our operations and to remain competitive;

• system failure, outages or interruptions, including with respect to our AVAX custodian and our platforms, including those due to third-party actions;

• our lack of control over decentralized or third-party blockchains and networks that may experience downtime, cyberattacks, critical failures, errors, bugs, corrupted files, data losses or other similar software failures, outages, breaches and losses;

• breaches of security or privacy;

• decreases in AVAX staking reward percentage, due to an increase in the AVAX staking ratio;

• transaction congestion and gas fees associated with processing transactions on the AVAX network;

43

• developments in mathematics or technology, including in digital computing, algebraic geometry and quantum computing or new applications of current knowledge in these fields, that could result in the cryptography used by the Avalanche blockchain becoming insecure or ineffective;

• legal, commercial and regulatory uncertainty regarding AVAX and other digital assets due to their novelty, see “— AVAX and other digital assets are novel assets, which will expose Pubco to significant legal, commercial, regulatory and technical uncertainty, which could materially adversely affect Pubco’s financial position, operations and prospects”;

• changes in national and international economic and political conditions, including, without limitation, federal government policies, trade tariffs and trade disputes, the adverse impacts attributable to the current conflict between Russia and Ukraine and the economic sanctions adopted in response to the conflict and the broadening of the Israel-Hamas conflict in the Gaza Strip, and the ongoing conflicts in Syria and Lebanon, to other countries in the Middle East; our ability to establish and maintain any future partnerships, collaborations, joint ventures or strategic alliances with third parties; and

• our ability to attract and retain talent.

As a result of these factors, it is difficult for us to forecast growth trends accurately and our business and future prospects are difficult to evaluate, particularly in the short term.

Further, Pubco cannot predict what further action may be taken with respect to tariffs or trade relations between the U.S. and other governments. Any such changes could fundamentally alter the competitive and regulatory landscape in which Pubco operates, and political tensions as a result of trade policies could reduce trade volume, investment, technological exchange and other economic activities between major international economies, resulting in a material adverse effect on global economic conditions and the stability of global financial markets, all of which could potentially having a material adverse effect on our business, financial condition and results of operation.

In addition, the stock market and the markets for both digital asset influenced and technology companies have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of companies in those markets. In particular, future trading prices in Pubco Class A Stock may reflect market dynamics that are not connected to valuation methods commonly associated with operating companies in similar industries or with companies engaged predominantly in passive investments in AVAX or other commodities, such as ETFs. Equity market capitalizations of other such companies are often in excess of stockholders’ equity calculated in accordance with U.S. GAAP, and in excess of valuations that might traditionally be expected based on their operating performances, cash flows and net assets. Investors may therefore be unable to assess the value of the shares of Pubco Class A Stock or evaluate the risks of an investment in us using traditional or commonly used enterprise valuation methods. Pubco cannot predict how these dynamics may evolve over time, or whether or how long they may last. These market and industry factors may significantly harm the market price of Pubco Class A Stock, regardless of our actual operating performance.

Our AVAX acquisition strategy exposes us to various risks associated with AVAX.

Our AVAX acquisition strategy exposes us to various risks associated with AVAX, including the following:

AVAX is a highly volatile asset. For example, based on the New York variant of the CME CF Avalanche-Dollar Reference Rate (“CME CF ADRR”), AVAX has traded below $8.50 per AVAX and above $34.00 per AVAX in the 12 months preceding May 5, 2026. See “— Pubco’s operating results, revenues and expenses may significantly fluctuate, including due to the highly volatile nature of AVAX, which has had and could have in the future an adverse effect on the market price of Pubco Class A Stock.” See also “— Pubco may suffer losses due to abrupt and erratic market movements.”

Pubco’s AVAX holdings may significantly impact its financial results and in turn may impact the market price of Pubco Class A Stock. If we continue to increase our overall holdings of AVAX relative to the other parts of our business in the future, Pubco’s AVAX holdings will have an even greater impact on its financial results and the market price of Pubco Class A Stock. Pubco intends to purchase additional AVAX and increase its overall holdings of AVAX in the future.

The concentration of Pubco’s AVAX holdings limits the risk mitigation that it could take advantage of by purchasing a more diversified portfolio of treasury assets, and the absence of diversification enhances the risks inherent in our AVAX acquisition

44

strategy. See “— Pubco’s operating results, revenues and expenses may significantly fluctuate, including due to the highly volatile nature of AVAX, which has had and could have in the future an adverse effect on the market price of Pubco Class A Stock.” See also “— Pubco may suffer losses due to abrupt and erratic market movements.”

Pubco’s AVAX acquisition strategy has not been tested by us to date. While certain issuers have operating histories that involve digital asset acquisition strategies that may be comparable to the AVAX acquisition strategy Pubco intends to execute, these have not been tested over an extended period of time or under different market conditions. Pubco will continuously examine the risks and rewards of its AVAX acquisition strategy. For example, although Pubco believes AVAX, due to its immutable supply cap, is a quantifiable scarce assets that could protect against monetary debasement, if the short-term price of AVAX declines, Pubco’s financial condition, results of operations and the market price of Pubco Class A Stock may be materially adversely impacted. See also “— A significant decrease in the market value of Pubco’s AVAX holdings could adversely affect its ability to satisfy its financial obligations.”

Pubco’s AVAX acquisition strategy will expose it to the risk of non-performance by counterparties, whether contractual or otherwise. Risk of non-performance includes the inability or refusal of a counterparty to perform for any reason, including because of a deterioration in the counterparty’s financial condition and liquidity. Custodians, or other counterparties might fail to perform in accordance with the terms of future agreements with them, which could result in a loss of AVAX, a loss of the opportunity to generate funds, or other losses. Although Pubco will implement various measures that are designed to mitigate its counterparty risks, including by storing substantially all of the AVAX in custody accounts at U.S.-based, custodians that service institutions and negotiating contractual arrangements intended to establish that our property interest in custodially held AVAX is not subject to claims of our custodians’ creditors, applicable insolvency law is not fully developed with respect to the holding of digital assets in custodial accounts. While all of our custodians are expected to be subject to regulatory regimes intended to protect customers in the event of a custodial bankruptcy, receivership or similar insolvency proceeding, no assurance can be provided that our custodially held AVAX will not become part of the custodian’s insolvency estate if one or more of our custodians enter bankruptcy, receivership or similar insolvency proceedings. If our custodially held AVAX were nevertheless considered to be the property of our custodians’ estates in the event that any such custodians were to enter bankruptcy, receivership or similar insolvency proceedings, we could be treated as a general unsecured creditor of such custodians, inhibiting our ability to exercise ownership rights with respect to such AVAX and this may ultimately result in the loss of the value related to some or all of such AVAX. Even if we are able to prevent our AVAX from being considered the property of a custodian’s bankruptcy estate as part of an insolvency proceeding, it is possible that we would still be delayed or may otherwise experience difficulty in accessing our AVAX held by the affected custodian during the pendency of the insolvency proceedings. Any such outcome could have a material adverse effect on our financial condition and the market price of Pubco Class A Stock.

Pubco’s primary counterparty risk with respect to its AVAX is expected to be custodian performance obligations under the custody arrangements it will enter into. Additionally, if Pubco pursues any strategies to create income streams or otherwise generate funds using its AVAX holdings, other than staking to create rewards, it would become subject to additional counterparty risks. Any significant non-performance by counterparties, including in particular the custodians with which Pubco grants custody of substantially all of its AVAX, could have a material adverse effect on Pubco’s business, prospects, financial condition and operating results. See “Pubco will face risks relating to the custody of its AVAX, including the loss or destruction of private keys required to access its AVAX and cyberattacks or other data loss relating to its AVAX. If Pubco or its third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to Pubco’s AVAX, or if Pubco’s private keys are lost or destroyed, or other similar circumstances or events occur, including the ability to reverse engineer private keys, Pubco may lose some or all of its AVAX and Pubco’s financial condition and results of operations could be materially adversely affected.”

45

The broader digital assets industry is subject to counterparty risks, which could adversely impact the adoption rate, price and use of AVAX. For example, a series of high-profile bankruptcies, closures, liquidations, regulatory enforcement actions and other events relating to companies operating in the digital asset industry, including the filings for bankruptcy protection by Three Arrows Capital, Celsius Network, Voyager Digital, BlockFi Lending, Core Scientific, FTX Trading, Alameda Research and Genesis Global Capital, the closure or liquidation of certain financial institutions that provided lending and other services to the digital assets industry, including Silicon Valley Bank, Signature Bank and Silvergate Bank, the potential of SEC enforcement actions, the placement of Prime Trust, LLC into receivership following a cease-and- desist order issued by Nevada’s Department of Business and Industry, and the filing and subsequent settlements of lawsuits by the New York Attorney General against Galaxy Digital Holdings, Genesis Global Capital, Genesis’ parent company Digital Currency Group, Inc., and former partner Gemini Trust Company, had highlighted the counterparty risks applicable to owning and transacting in digital assets. Bankruptcies, closures, liquidations and other events may impact our access to AVAX and could negatively impact the adoption rate and use of Avalanche and AVAX. Additional bankruptcies, closures, liquidations, regulatory enforcement actions or other events involving participants in the digital assets industry in the future may further negatively impact the adoption rate, price and use of AVAX, limit the availability to us of financing collateralized by AVAX or create or expose additional counterparty risks.

The broader digital assets industry, including the technology associated with digital assets, the rate of adoption and development of and use cases for, digital assets, market perception of digital assets and the legal, regulatory, and accounting treatment of digital assets are constantly developing and changing, and there may be additional risks in the future that are not possible to predict. See “— AVAX and other digital assets are novel assets, which will expose Pubco to significant legal, commercial, regulatory and technical uncertainty, which could materially adversely affect Pubco’s financial position, operations and prospects.”

A significant decrease in the market value of Pubco’s AVAX holdings could adversely affect Pubco’s ability to satisfy its financial obligations.

As of the Closing, our total liabilities will be $35,323,191 million in the no redemption scenario, or $60,323,191 in the maximum redemption scenario. As part of our AVAX strategy, Pubco may incur or continue to incur additional indebtedness and other fixed charges. If our businesses do not generate cash flow in future periods sufficient to satisfy our financial obligations, including our debt and other financial obligations, Pubco intends to fund its obligations using cash flow generated by equity or debt financings. Pubco’s ability to obtain equity or debt financing may in turn depend on, among other factors, the value of its AVAX holdings, investor sentiment and the general public perception of AVAX, Pubco’s strategy and its value proposition. Accordingly, a significant decline in the market value of Pubco’s AVAX holdings or a negative shift in these other factors may create liquidity and credit risks, as such a decline or such shifts may adversely impact Pubco’s ability to secure sufficient equity or debt financing to satisfy its financial obligations, including its debt and other financial obligations. These risks could materialize at times when AVAX is trading below its carrying value on its most recent balance sheet or below its cost basis. Any such sale of AVAX may have a material adverse effect on Pubco’s operating results and financial condition, and could impair its ability to secure additional equity or debt financing in the future. Pubco’s inability to secure additional equity or debt financing in a timely manner, on favorable terms or at all, or to sell our AVAX in amounts and at prices sufficient to satisfy its financial obligations, including its debt service obligations, could cause Pubco to default under such obligations. Any default on Pubco’s indebtedness may have a material adverse effect on its financial condition.

Pubco will operate in a highly competitive environment and will compete against companies and other entities with similar strategies, including companies with significant AVAX holdings and ETFs and ETPs for AVAX. Pubco’s business, operating results and financial condition may be adversely affected if Pubco is unable to compete effectively.

The digital assets industry is highly innovative, rapidly evolving and characterized by healthy competition, experimentation, changing customer needs, frequent introductions of new products and services, and subject to uncertain and evolving industry and regulatory requirements. Pubco expects competition to further intensify in the future. Pubco competes against a number of companies operating both within the United States and abroad, and both those that focus on traditional financial services and those that focus on Avalanche-based services. Pubco’s main competition falls into the following categories:

• traditional financial firms that have entered the Avalanche ecosystem in recent years and offer overlapping features targeted at our future customers;

• financial technology providers that do not focus on Avalanche and may attempt to position themselves as a safer alternative to our future products and services;

46

• companies with significant AVAX holdings or companies that pursue an AVAX treasury strategy; and

• companies focused on the Avalanche ecosystem, some of whom choose to operate outside of local rules and regulations or in jurisdictions with less stringent local rules and regulations and are potentially able to more quickly adapt to trends and to develop new Avalanche-based products and services due to a different standard of regulatory scrutiny.

If Pubco is unable to compete successfully, or if competing successfully requires Pubco to take costly actions in response to the actions of its competitors, its business, operating results and financial condition could be adversely affected.

The range of options to gain exposure to AVAX may expand in the future. If investors choose to gain such exposure through ETPs, companies with significant AVAX holdings or other similar strategies, rather than shares of Pubco Class A Stock, Pubco’s business, operating results and financial condition may be adversely affected.

Investors may view Pubco Class A Stock as an alternative to an investment in an ETP, and choose to purchase shares of a spot AVAX ETP instead of Pubco Class A Stock. They may do so for a variety of reasons, including if they believe that ETPs offer a “pure play” exposure to AVAX that is generally not subject to federal income tax at the entity level as Pubco may be, or the other risks that may affect other parts of its business. Additionally, unlike spot AVAX ETPs, Pubco (i) does not seek for its shares of Pubco Class A Stock to passively track the value of the underlying AVAX it holds, (ii) does not benefit from various exemptions and relief under the Exchange Act, including Regulation M, and other securities laws, which enable ETPs to continuously align the value of their shares to the price of the underlying assets they hold through share creation and redemption, (iii) is a Delaware corporation rather than a statutory trust, and does not operate pursuant to a trust agreement that would require Pubco to pursue one or more stated investment objectives and (iv) is not required to provide daily transparency as to its AVAX holdings or daily net asset value. Furthermore, recommendations by broker-dealers to buy, hold or sell complex products and non- traditional ETPs, or an investment strategy involving such products, may be subject to additional or heightened scrutiny that would not be applicable to broker-dealers making recommendations with respect to Pubco Class A Stock. Based on how Pubco is viewed in the market relative to ETPs, and other vehicles which offer economic exposure to AVAX, such as potential AVAX futures ETFs, leveraged AVAX futures ETFs and similar vehicles offered on international exchanges, any premium or discount in Pubco Class A Stock relative to the value of its AVAX holdings may increase or decrease in different market conditions.

As a result of the foregoing factors, availability of spot ETPs for AVAX and other digital assets could have a material adverse effect on the market price of Pubco Class A Stock.

Pubco may suffer losses due to abrupt and erratic market movements.

The AVAX market has been characterized by significant volatility and unexpected price movements. AVAX may become more volatile and less liquid in a very short period of time. As previously discussed in this section, a series of recent high-profile bankruptcies, closures, liquidations, regulatory enforcement actions and other events relating to companies operating in the digital asset industry have highlighted the counterparty risks applicable to owning and transacting in digital assets. See “Pubco’s operating results, revenues and expenses may significantly fluctuate, including due to the highly volatile nature of AVAX, which has had and could have in the future an adverse effect on the market price of Pubco Class A Stock.”

These bankruptcies, closures, liquidations and other events have created significant volatility in the markets for cryptocurrency generally. Additional bankruptcies, closures, liquidations, regulatory enforcement actions or other events involving participants in the digital assets industry in the future could result in market prices being subject to erratic and abrupt market movement, which could harm our business. Further, because there is no centralized authority which determines the price of AVAX, pricing often differs between exchanges. When some exchanges are viewed as higher risk, that price differential can widen as traders attempt to exploit these differences. Volatility in the price of AVAX, as well as the lack of a standard price, could lead consumers to see AVAX as an unsafe asset. In addition, if Pubco were to attempt to monetize the AVAX it holds on its balance sheet, such price volatility could lead to trading losses, impacting Pubco’s financial position.

For example, based on the CME CF ADRR index, on May 1, 2025, the price of AVAX was $21.2883. On May 5, 2026, the price of AVAX was $9.4059.

47

The trading volume of AVAX typically increases during periods of extreme volatility. For example, in the days following the U.S. federal elections in November 2024, the price of AVAX rose sharply from $24.0084 on November 2, 2024, to $55.6974 on December 4, 2024. Such volume increases can lead to extreme pressures on trading platforms and infrastructure that can lead to inadvertent suspension of services across parts of the platforms or the entire platforms, and Pubco may experience outages. Outages can lead to increased service expense, can cause reputational damage, result in inquiries and actions by regulators, and can lead to other damages for which Pubco may be responsible, any of which could harm our business.

The emergence or growth of other digital assets, including those with significant private or public sector backing, including by governments, consortiums or financial institutions, could have a negative impact on the price of AVAX and adversely affect Pubco’s business.

As a result of our AVAX acquisition strategy, a substantial part of our assets will be concentrated in our AVAX holdings. Accordingly, the emergence or growth of digital assets other than AVAX may have a material adverse effect on our financial condition. There are numerous alternative digital assets and many entities, including consortiums and financial institutions, are researching and investing resources into private or permissioned blockchain platforms or digital assets that do not use proof-of-work mining like the Bitcoin network or utilize a “proof-of-stake” mechanism similar to Avalanche.

Additionally, central banks in some countries have started to introduce digital forms of legal tender. For example, China’s central bank digital currency project was made available to consumers in January 2022, and governments including the United States, the European Union, and Israel have been discussing the potential creation of new central bank digital currencies. Whether or not they incorporate blockchain or similar technology, central bank digital currencies, as legal tender in the issuing jurisdiction, could also compete with, or replace, digital assets as a medium of exchange or store of value. As a result, the emergence or growth of these or other digital assets could cause the market price of AVAX to decrease, which could have a material adverse effect on our business, prospects, financial condition and operating results.

Pubco’s AVAX holdings will be less liquid than its cash and cash equivalents and may not be able to serve as a source of liquidity for Pubco.

A substantial part of Pubco’s assets will be AVAX. Further, historically, the digital asset markets have been characterized by significant volatility in price, limited liquidity and trading volumes compared to sovereign currencies markets, relative anonymity, a developing regulatory landscape, potential susceptibility to market abuse and manipulation, compliance and internal control failures at exchanges and various other risks inherent in its entirely electronic, virtual form and decentralized network. During times of market instability, Pubco may not be able to sell our AVAX at favorable prices or at all. For example, a number of digital asset trading venues temporarily halted deposits and withdrawals of Bitcoin in 2022, although the Coinbase, Inc. exchange has, to date, not done so. As a result, our AVAX holdings may not be able to serve as a source of liquidity for us to the same extent as cash and cash equivalents. Further, AVAX held by custodians, including our custodians, does not enjoy the same protections as are available to cash or securities deposited with or transacted by institutions subject to regulation by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation. Additionally, Pubco may be unable to enter into term loans, bonds or other capital raising transactions collateralized by its unencumbered AVAX or otherwise generate funds using its AVAX holdings, including, in particular, during times of market instability or when the price of AVAX has declined significantly. If Pubco is unable to sell its AVAX, enter into additional capital raising transactions using unencumbered AVAX as collateral, or otherwise generate fiat funds using its AVAX holdings, or if Pubco is forced to sell its AVAX at a significant loss, in order to meet its debt obligations, or its working capital requirements, our business and financial condition could be negatively impacted.

The Avalanche Network and its native digital asset, AVAX is a relatively new technological innovation with a limited operating history.

AVAX has a relatively limited history of existence and operations compared to traditional commodities. There is a limited established performance record for the price of AVAX and, in turn, a limited basis for evaluating an investment in AVAX. Although past performance is not necessarily indicative of future result, if AVAX had a more established history, such history might (or might not) provide investors with more information on which to evaluate an investment in the trust.

48

AVAX is created and transmitted through the operations of the peer-to-peer Avalanche Network, a decentralized network of computers running software following the Avalanche protocol. If the Avalanche Network is disrupted or encounters any unanticipated difficulties, the value of AVAX could be negatively impacted.

If the Avalanche Network is disrupted or encounters any unanticipated difficulties, then the processing of transactions on the Avalanche platform may be disrupted, which in turn may prevent Pubco from depositing or withdrawing AVAX from its accounts with its custodian or otherwise effecting AVAX transactions. Such disruptions could include, for example: the price volatility of AVAX; the insolvency, business failure, interruption, default, failure to perform, security breach, or other problems of participants, custodians, or others; the closing of AVAX trading platforms due to fraud, failures, security breaches, or otherwise; or network outages or congestion, power outages, or other problems or disruptions affecting the Avalanche network. On February 23, 2024, Avalanche’s C-Chain experienced “an excessive amount of gossip,” or more information passing between validator nodes than necessary, which caused the Avalanche Network to go offline for almost five hours before a software patch corrected the issue. Any future disruptions to the Avalanche Network due to software malfunctions causing the Avalanche Network to go offline or otherwise preventing the creation of new blocks could have a material adverse effect on the price of AVAX and on the value of an investment in shares of Pubco Stock.

Internet disruption or a border gateway protocol hijacking event may affect Avalanche network operations, which may adversely affect the value of AVAX and an investment in Pubco.

The Avalanche Network relies on the Internet. A significant disruption of Internet connectivity could disrupt the Avalanche Network’s functionality and operations until the disruption in the Internet is resolved. A disruption in the Internet could adversely affect an investment in Pubco or the ability of Pubco to operate. In particular, some variants of digital assets have experienced a number of denial-of-service attacks, which have led to temporary delays in block creation and digital asset transfers. Moreover, it is possible that as AVAX increases in value, it may become a bigger target for hackers and may be subject to more frequent hacking and denial-of-service attacks.

Digital assets are also susceptible to border gateway protocol hijacking (“BGP Hijacking”). Such an attack can be a very effective way for an attacker to intercept traffic en route to a legitimate destination. BGP Hijacking impacts the way different nodes are connected to one another to isolate portions from the remainder of the network. A successful attack could lead the network to allow double-spending or create other security issues. If BGP Hijacking occurs on the Avalanche Network, participants may lose faith in the security of AVAX, which could affect the value of AVAX and consequently the value of shares of Pubco Stock.

Any future attacks that impact the ability to transfer AVAX could have a material adverse effect on the price of AVAX and the value of an investment in shares of Pubco Stock.

Pubco will face risks associated with AVAX delegation, staking, liquid staking and associated lock-ups.

AVAX held by Pubco may be staked to validators to maximize staking rewards. However, staking and liquid staking involves a number of risks that could materially affect the liquidity, value, and utility of the AVAX. When AVAX is staked it is locked by a validator node and used to secure the Avalanche Network, in turn creating staking rewards. Staked AVAX is illiquid and cannot be transferred or sold until the specified lock-up period ends. During the lock-up period, Pubco cannot use that AVAX to respond to market conditions, price volatility, or for liquidity purposes, except in the case of liquid staking, wherein Pubco can receive liquid staking tokens in return for the deposit of AVAX into a locked protocol (preserving partial asset liquidity). Market conditions for AVAX are rapidly changing, and longer staking durations can amount to less liquidity in periods where greater liquidity is desired. Furthermore, staking and liquid staking rewards are not guaranteed and reward rates are subject to fluctuation. The staking mechanism itself may be subject to technical failures, changes in network parameters or vulnerabilities in the protocol which could negatively impact our staked as well as liquid staked tokens. In the event of a network attack, governance failure, or significant market downturn, staked and liquid staked tokens, particularly tokens which care locked for an extended period, may be at heightened risk of devaluation or loss.

In relation to liquid staking in particular, both stAVAX and sAVAX rely on smart contracts deployed on the Avalanche C-Chain. Although the Hypha protocol, the decentralized liquid staking and validator infrastructure protocol on the Avalanche C-Chain which issues stAVAX (“Hypha Protocol”), and the BENQI protocol, the decentralized liquid staking and validator infrastructure protocol on the Avalanche C-Chain which issues interest-bearing sAVAX (“BENQI Protocol”), each disclosed that they have undergone third-

49

party security audits, smart contracts may contain undiscovered bugs or vulnerabilities that could be exploited, potentially resulting in a partial or total loss of the underlying staked AVAX. Smart contract risk is inherent to all DeFi protocols and cannot be fully eliminated through auditing.

The Hypha and BENQI protocols are each managed by relatively small teams and governed by their respective token-holder decentralized autonomous organizations (“DAOs”). Governance token holders could vote to implement changes that adversely affect the terms of liquid staking, including changes to fee structures, redemption processes or validator selection criteria. The Company does not hold governance tokens in either protocol and therefore has no ability to influence governance decisions. Changes to protocol parameters, fee structures or operational decisions made through governance processes could adversely affect the value or redeemability of the Company’s liquid staking tokens. Additionally, either protocol could cease operations, experience a governance failure or become subject to an attack that compromises its functionality.

Both sAVAX and stAVAX are less liquid than the underlying AVAX token. In the case of both sAVAX and stAVAX, holders may alternatively sell on decentralized exchanges, but doing so may result in receiving less than the theoretical exchange rate, particularly in periods of market stress or low liquidity. Neither token is widely listed on centralized exchanges, which concentrates trading in on-chain pools and may amplify price dislocations during periods of high sell pressure. The values of stAVAX and sAVAX are directly correlated to the value of the underlying AVAX token, which is subject to significant price volatility. In addition, while both tokens are designed to maintain a predictable and increasing exchange rate relative to AVAX, they may trade at a discount to their theoretical value on secondary markets due to liquidity constraints, market sentiment or concerns about the underlying protocols. There can be no assurance that the Company would be able to redeem or sell its liquid staking tokens at or near their theoretical exchange rate.

Pubco will face risks associated with the concentration of its holdings of stAVAX and sAVAX.

As of May 4, 2026, the Company held approximately 42% of the outstanding supply of stAVAX and approximately 10% of the outstanding supply of sAVAX. This significant concentration of ownership in liquid staking tokens could adversely affect the liquidity, market price stability and overall functioning of the stAVAX and sAVAX ecosystems. Due to the size of these positions, the Company may be unable to liquidate or redeem its holdings of stAVAX or sAVAX without materially and adversely affecting prevailing market prices. Moreover, any actual or perceived sales or redemptions by the Company could result in heightened volatility, reduced liquidity, widening discounts relative to the underlying value of AVAX and diminished market confidence in these tokens, any of which could in turn adversely affect the value of the Company’s remaining holdings.

In addition, this concentration of ownership may amplify risks associated with validator performance, redemption queue delays, smart contract vulnerabilities, governance influence and broader market disruptions affecting the Avalanche Network or liquid staking protocols generally. To the extent the Company’s holdings represent a disproportionate share of the circulating supply of stAVAX or sAVAX, the foregoing risks may be magnified, and the Company’s ability to manage or mitigate such risks may be limited. Although the Company does not currently intend to hold more than 30% of its total assets in liquid staking tokens, there can be no assurance that this threshold will not be exceeded from time to time as a result of market movements, changes in outstanding token supply or other factors beyond the Company’s control, or that this threshold will be sufficient in mitigating any of the foregoing risks. The current concentration, or any future increase in the concentration, of the Company's holdings in liquid staking tokens could have a material adverse effect on the Company's business, financial condition, results of operations and the trading price of the Pubco Class A Stock.

Pubco will face risks relating to the custody of its AVAX, including the loss or destruction of private keys required to access our AVAX and cyberattacks or other data loss relating to our AVAX. If Pubco or its third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to Pubco’s AVAX, if Pubco’s private keys are lost or destroyed, or other similar circumstances or events occur, including the ability to reverse engineer private keys, Pubco may lose some or all of its AVAX and Pubco’s financial condition and results of operations could be materially adversely affected.

We will hold our AVAX with a regulated custodian that has duties to safeguard our private keys. Generally, custodial services contracts do not restrict the ability to reallocate AVAX among custodians. However, all of the AVAX that we will own will initially be held in custody accounts at Coinbase, BitGo and Anchorage. In light of the significant amount of AVAX we will hold, we may seek to engage additional custodians to achieve a greater degree of diversification in the custody of our AVAX as the extent of potential risk of loss is dependent, in part, on the degree of diversification. If there is a decrease in the availability of digital asset custodians that we believe can safely custody our AVAX, for example, due to regulatory developments or enforcement actions that

50

cause custodians to discontinue or limit their services in the United States, we may need to enter into agreements that are less favorable or take other measures to custody our AVAX, and our ability to seek a greater degree of diversification in the use of custodial services could be materially adversely affected. Coinbase, our initial custodian, maintains an insurance policy, however, such insurance may not be available or sufficient to protect Pubco from any or all possible losses or sources of losses.

Insurance to cover losses of our future AVAX holdings will likely only cover a small fraction of the value of the entirety of the AVAX holdings, and there can be no guarantee that such insurance may be obtained or maintained as part of the custodial services we will have or that such coverage will cover losses with respect to our AVAX. Moreover, our use of custodians exposes us to the risk that the AVAX our custodians will hold on our behalf could be subject to insolvency proceedings and we could be treated as a general unsecured creditor of the custodian, inhibiting our ability to exercise ownership rights with respect to such AVAX. Any loss associated with such insolvency proceedings is unlikely to be covered by any insurance coverage we will maintain related to our AVAX.

AVAX is controllable only by the possessor of both the unique public key and private key(s) relating to the local or online digital wallet in which the AVAX is held. While the AVAX blockchain ledger requires a public key relating to a digital wallet to be published when used in a transaction, private keys must be safeguarded and kept private in order to prevent a third party from accessing the AVAX held in such wallet. To the extent the private key(s) for a digital wallet are lost, destroyed, or otherwise compromised and no backup of the private key(s) is accessible, neither we nor our custodians will be able to access the AVAX held in the related digital wallet. Furthermore, we cannot provide assurance that our digital wallets, nor the digital wallets of our custodians held on our behalf, will not be compromised as a result of a cyberattack. The Avalanche blockchain, as well as other digital assets and blockchain technologies, have been, and may in the future be, subject to security breaches, cyberattacks or other malicious activities.

Security breaches and cyberattacks are of particular concern with respect to our AVAX. AVAX and other blockchain-based cryptocurrencies and the entities that provide services to participants in the Avalanche ecosystem have been, and may in the future be, subject to security breaches, cyberattacks or other malicious activities. For example, in October 2021 it was reported that hackers exploited a flaw in the account recovery process and stole from the accounts of at least 6,000 customers of the Coinbase, Inc. exchange, although the flaw was subsequently fixed and Coinbase, Inc. reimbursed affected customers. Similarly, in November 2022, hackers exploited weaknesses in the security architecture of the FTX Trading Ltd. digital asset exchange and reportedly stole over $400 million in digital assets from customers. In 2024, hackers stole an estimated total of $2.2 billion in digital assets from cryptocurrency platforms. In February 2025, $1.5 billion of digital assets was stolen from a single cryptocurrency exchange, Bybit, operated by Bybit Fintech Limited. A successful security breach or cyberattack could result in:

• a partial or total loss of our AVAX in a manner that may not be covered by insurance or the liability provisions of the custody agreements with the custodians who hold our AVAX;

• harm to our reputation and brand;

• improper disclosure of data and violations of applicable data privacy and other laws; or

• significant regulatory scrutiny, investigations, fines, penalties and other legal, regulatory, contractual and financial exposure.

Further, any actual or perceived data security breach or cybersecurity attack directed at other companies with digital assets or companies that operate digital asset networks, regardless of whether we are directly impacted, could lead to a general loss of confidence in the broader Avalanche ecosystem or in the use of the Avalanche Network to conduct financial transactions, which could negatively impact us.

Attacks upon systems across a variety of industries, including industries related to Avalanche, are increasing in frequency, persistence and sophistication, and, in many cases, are being conducted by sophisticated, well-funded and organized groups and individuals, including state actors. The techniques used to obtain unauthorized, improper or illegal access to systems and information (including personal data and digital assets), disable or degrade services, or sabotage systems are constantly evolving, may be difficult to detect quickly, and often are not recognized or detected until after they have been launched against a target. These attacks may occur on our systems or those of our third-party service providers or partners. We may experience breaches of our security measures due to human error, malfeasance, insider threats, system errors or vulnerabilities or other irregularities. In particular, unauthorized parties may attempt, to gain access to our systems and facilities, as well as those of our partners and third-party service providers,

51

through various means, such as hacking, social engineering, phishing and fraud. Threats can come from a variety of sources, including criminal hackers, hacktivists, state-sponsored intrusions, industrial espionage and insiders. In addition, certain types of attacks could harm us even if our systems are left undisturbed. For example, certain threats are designed to remain dormant or undetectable, sometimes for extended periods of time or until launched against a target and we may not be able to implement adequate preventative measures. The risk of cyberattacks could also be increased by cyberwarfare in connection with the ongoing Russia-Ukraine and Israel-Hamas conflicts, or other future conflicts, including potential proliferation of malware into systems unrelated to such conflicts. Any future breach of our operations or those of others in the Avalanche industry, including third-party services on which we rely, could materially and adversely affect our business.

Our limited insurance protection exposes us and our shareholders to the risk of loss of our AVAX for which no person is liable.

We do not expect to maintain insurance coverage for our AVAX holdings, which will be held in custody by our custodians. Our future custodians may maintain a certain insurance coverage of such types and amounts as they assert to be commercially reasonable for their custodial services provided under our custody agreements with them, including certain commercial crime insurance of limited aggregate principal amount which covers losses stemming from fraud, security breach, hack and asset theft. However, as insurance coverage is generally shared among all customers of each given custodian, such insurance coverage may be insufficient to protect us against all losses of our AVAX holdings held in custody with our custodians, whether or not stemming from security breaches, cyberattacks or other types of unlawful activity. Therefore, a loss may be suffered with respect to our AVAX that is not covered by insurance and for which no person is liable in damages, which could adversely affect our operations and, consequently, an investment in us.

The accounting treatment of our AVAX holdings are likely to have significant accounting impacts, including volatility of our results. If financial accounting standards undergo significant changes, our operating results could fluctuate.

In December 2023, the FASB issued ASU 2023-08, effective for fiscal years beginning after December 15, 2024. Pubco will be required to adopt ASU 2023-08, which will require us to measure in-scope crypto assets (including our AVAX holdings) at fair value in our statement of financial position, and to recognize gains and losses from changes in the fair value of our AVAX in net income each reporting period. ASU 2023-08 will also require us to provide certain interim and annual disclosures with respect to our AVAX holdings. The Company’s stAVAX are intangible assets that do not meet the criteria in ASC 350-60-15-1 and are accounted for as indefinite-lived intangible assets. Therefore, the Company tests the digital intangible assets for impairment when events or changes in circumstances indicate that fair value is below carrying amount. Due in particular to the volatility in the price of AVAX, and impact on stAVAX should value drop below carrying amount, we expect the adoption of ASU 2023-08 to have a material impact on our financial results in future periods, including the volatility of our financial results, and affect the carrying value of our AVAX on our balance sheet, and it could also have adverse tax consequences, which in turn could have a material adverse effect on our financial results and the market price of Pubco Class A Stock.

The broader digital assets industry, including the technology associated with digital assets, the rate of adoption and development of and use cases for, digital assets, market perception of digital assets and the legal, regulatory, and accounting treatment of digital assets are constantly developing and changing, and there may be additional risks in the future that are not possible to predict. Uncertainties in or changes to regulatory or financial accounting standards could result in the need to change our accounting methods and may retroactively affect previously reported results and impair our ability to provide timely and accurate financial information, which could adversely affect our financial statements, result in a loss of investor confidence, and our business, operating results and financial condition.

AVAX and other digital assets are novel assets, which will expose Pubco to significant legal, commercial, regulatory and technical uncertainty, which could materially adversely affect Pubco’s financial position, operations and prospects.

AVAX and other forms of digital assets are relatively novel and have been the source of much regulatory uncertainty, resulting in differing definitional outcomes without a single unifying statement, which subjects them to significant uncertainty that could adversely impact their price.

AVAX and other digital assets are viewed differently by different regulatory and standards setting organizations globally as well as in the United States on the federal and state levels. Certain governments have prohibited certain digital asset activities or have severely curtailed the use of digital assets by prohibiting the acceptance of payment in AVAX and other digital assets for consumer transactions and barring banking institutions from accepting deposits of digital assets. Other nations, however, allow digital assets to be used and traded without restriction. In some jurisdictions, such as in the United States, digital assets are subject to extensive, and in

52

some cases overlapping, unclear and evolving regulatory requirements. There is a risk that relevant authorities in any jurisdiction may impose more onerous regulation on AVAX, for example banning its use, regulating its operation, or otherwise changing its regulatory treatment. The application of state and federal securities laws and other laws and regulations to digital assets is unclear in certain respects, and it is possible that regulators in the United States or foreign countries may interpret or apply existing laws and regulations in a manner that may introduce a cost of compliance, make our current business model no longer viable, or have a material impact on our business model, and therefore our financial performance and shareholder returns, and/or adversely affect the price of AVAX. The U.S. federal government, states, regulatory agencies and foreign countries have recently enacted and may also enact additional new laws and regulations, or pursue regulatory, legislative, enforcement or judicial actions, that could materially impact the price of AVAX, the ability of individuals or institutions such as us to own or transfer AVAX, and/or the competitive landscape for our products and services. For example:

• On January 23, 2025, President Trump signed an Executive Order to promote the growth and use of digital assets, blockchain technology and related technologies across all sectors of the economy. Among other things, the Executive Order established a working group comprised of representatives from key federal agencies, tasked with developing a federal regulatory framework for digital assets and evaluating measures that can be taken to provide regulatory clarity and certainty built on technology- neutral regulations for individuals and firms involved in digital assets, including through well- defined jurisdictional regulatory boundaries. On July 30, 2025, such working group published a report on strengthening American leadership in digital financial technology, which recommended several regulatory and legislative proposals to advance President Trump’s January 2025 Executive Order. The Executive Order also instructed the U.S. Department of Treasury, the SEC, and other relevant agencies to identify regulations, guidance, documents, orders and other items affecting the digital asset sector and submit recommendations for what should be rescinded, modified or, to the extent applicable, adopted into regulations. Additionally, it revoked President Biden’s prior Executive Order from March 9, 2022, relating to cryptocurrencies, and all policies, directives and guidance issued pursuant to that Executive Order, including the Department of the Treasury’s framework for international engagement on digital assets issued on July 7, 2022 and the White House framework for digital asset development released on September 16, 2022. The establishment of a new working group within the National Economic Council to propose a federal regulatory framework for digital assets could lead to significant changes in market structure, oversight, consumer protection and risk management. The evolving regulatory environment may pose challenges to our operations, particularly if new regulations introduce additional compliance costs or restrict certain activities.

• There have also been several bills introduced in Congress that propose to establish additional regulation and oversight of the digital asset markets, including certain legislation to establish a federal supervisory framework for payment stablecoins. With respect to stablecoins, on July 17, 2025, the U.S. Congress passed the GENIUS Act (“GENIUS Act”), which was signed into law by President Donald Trump on July 18, 2025. The GENIUS Act introduces the first federal regulatory framework for payment stablecoins, addressing consumer protection, financial stability, national security and anti-money laundering compliance, and establishes prudential requirements for the issuance, reserve backing and supervision of U.S. dollar- pegged stablecoins. However, it is not yet in effect and certain provisions depend on final implementing regulations, which are to be issued by the primary federal stablecoin regulators. As a result, we may be subject to certain regulatory requirements and restrictions. This may implicate new costs for us and our management may have to devote increased time and attention to regulatory matters or change aspects of our business. Additionally, the regulatory treatment of fiat-backed stablecoins across other jurisdictions remains uncertain.

• Increased regulation may also result in limitations on the use cases of AVAX. In addition, regulatory developments may require us to comply with certain existing and new regulatory regimes, such as if any of our activities cause us to be deemed a “money service business” under the regulations promulgated by the Financial Crimes Enforcement Network of the United States under the authority of the U.S. Bank Secrecy Act, including those that would require us to implement certain anti- money laundering programs, submit certain reports to Financial Crimes Enforcement Network of the United States and maintain certain records.

• In addition to the stablecoin legislation, the U.S. Congress has continued to take steps towards enacting legislation regarding the digital assets market structure. For instance, on July 17, 2025, the U.S. House of Representatives passed the CLARITY Act, which — if ultimately enacted — would allocate jurisdiction between the SEC and CFTC with respect to digital assets and create a market-structure framework for digital commodities; the bill also seeks to resolve regulatory ambiguity regarding the meaning of “security” and “commodity” using a classification system under which more decentralized digital assets, and secondary trading in digital assets, would be regulated by the CFTC and initial offerings of more centralized

53

digital assets would be regulated by the SEC. The U.S. Senate is also considering legislation that would provide a comprehensive regulatory framework for digital assets. The U.S. Senate Committee on Banking, Housing, and Urban Affairs released an initial discussion draft of the Responsible Financial Innovation Act of 2025 (“RFIA”) in July 2025, a second discussion draft in September 2025 and, on January 12, 2026, the Chairman Tim Scott released a proposed amendment to the RFIA, which currently remains under negotiation. The RFIA proposes a comprehensive regulatory framework for digital assets aimed at clarifying jurisdiction, enhancing consumer protections and fostering innovation. It seeks to resolve whether digital assets should be regulated as securities or commodities by introducing the concept of “ancillary assets,” which include digital assets offered through the sale of an investment contract. The SEC would have jurisdiction over initial offerings of ancillary assets, but secondary trading in ancillary assets would be excluded from the definition of security. In addition, the U.S. Senate Committee on Agriculture, Nutrition, and Forestry has advanced the Digital Commodity Intermediaries Act (“DCIA”), which like the CLARITY Act, would subject spot trading of digital assets that are commodities to regulation by the CFTC. It is an open question as to how the Senate will proceed.

• The U.S. federal banking agencies have enhanced the supervision of activities conducted by banking organizations. While recent regulatory developments suggest a more measured approach to crypto- related banking services and shifts on risk management practices signaling that debanking of digital asset industry participants without individualized risk assessments would not be supported, there is no guarantee that similar measures will not be reintroduced in the future. If banking restrictions tighten due to a shift in U.S. regulatory priorities, the digital asset ecosystem could face challenges in securing banking relationships, which could impact digital asset liquidity, market stability, operational security and institutional adoption, all of which could negatively affect the digital assets market and therefore the value of digital assets.

• On April 14, 2023, the SEC re-opened the comment period for its proposal to amend the definition of “exchange” under Exchange Act Rule 3b-16 to encompass trading and communication protocol systems for digital asset securities and trading systems that use distributed ledger or blockchain technology, including both so-called “centralized” and “decentralized” trading systems. On June 12, 2025 the SEC issued a notice to withdraw this proposal. If the SEC seeks to adopt a similar proposal in the future, the new definition would have a sweeping impact on digital asset trading venues and other digital asset industry participants.

• On January 21, 2025, the SEC announced that then-Acting SEC Chairman Mark Uyeda “launched a crypto task force dedicated to developing a comprehensive and clear regulatory framework for crypto assets.” The task force is focused on helping the SEC to “draw clear regulatory lines, provide realistic paths to registration, craft sensible disclosure frameworks and deploy enforcement resources judiciously.” While the SEC has formed the crypto task force to provide clarity on the application of the federal securities laws to the crypto asset market and to recommend practical policy measures that aim to foster innovation and protect investors, the task force has only recently begun. Additionally, on April 4, 2025, the SEC issued a statement concluding that “covered stablecoins” do not involve the offer or sale of securities within the meaning of the Securities Act or Exchange Act. While it provided a definition of what is a “covered stablecoin,” it is still unclear how this determination would affect non-covered stablecoins, and how it would interact with other proposed bills and regulations proposed by other agencies.

• On April 8, 2025, CFTC Acting Chairman Caroline Pham directed CFTC Staff, pursuant to Executive Order 14219, to deprioritize actions involving violations of registration requirements under the Commodity Exchange Act unless there is evidence that the non-registrant knew of the registration requirement and violated it willfully. The CFTC’s deprioritization of such enforcement actions, including against unregistered intermediaries who offer derivatives trading on crypto-assets, could add risk to the digital asset ecosystem. On December 16, 2025, the CFTC withdrew its prior interpretive guidance on Retail Commodity Transactions Involving Certain Digital Assets, creating uncertainty regarding when “actual delivery” occurs in the context of virtual currency transactions involving leverage and margin, which are subject to CFTC regulation as retail commodity transactions.

• In July 2025, the SEC unveiled “Project Crypto”, an SEC initiative to develop a flexible regulatory framework to accommodate cryptocurrencies and blockchain-based trading. Key components of “Project Crypto” are to, among other things, (i) provide clarity on crypto asset classification and offerings, (ii) facilitate tokenized securities and DeFi integration, (iii) facilitate custody of crypto assets for market intermediaries and multiple business lines, (iv) develop formal rules proposals under “Project Crypto” while using interpretative or exemptive relief where possible and (iv) consider a

54

potential “innovation exemption” to allow firms to deploy novel business models and technologies without full compliance with existing regulations upon meeting certain conditions.

• In August 2025, the Division of Corporation Finance of the SEC issued a statement providing interpretative clarity on the application of federal securities laws to certain liquid staking activities involving crypto assets. Liquid staking refers to a process in which holders of crypto assets deposit their assets with a third-party protocol staking service provider and receive newly minted crypto assets in return. In this statement, the SEC’s view is that liquid staking activities do not involve the offer and sale of securities within the meaning of Section 2(a)(1) of the Securities Act or Section 3(a)(10) of the Exchange Act. Accordingly, it is the SEC’s view that participants in liquid staking activities do not need to register with the SEC transactions under the Securities Act, or fall within one of the Securities Act’s exemptions from registration in connection with these liquid staking activities. The SEC also stated that it does not consider “staking receipt tokens” as securities, as they function as receipts evidencing ownership of the deposited crypto assets, which themselves are not securities.

• In August 2025, the CFTC launched its Listed Spot Crypto Trading Initiative, which aims to establish a framework for retail trading of leveraged, margined, or financed spot crypto asset contracts on CFTC-registered designated contract markets. The initiative would utilize existing authority under the CEA, which requires that retail trading of commodities with leverage, margin, or financing must be conducted on designated contract markets. The CFTC is exploring how to implement such a framework using current regulatory powers. While not final, the initiative may contribute to wider adoption of digital assets by clarifying how existing regulated venues could be used for retail trading of leveraged, margined, or financed spot crypto asset contracts. On September 2, 2025, the staffs of the SEC and CFTC issued a joint statement regarding trading of certain spot crypto asset products on regulated exchanges. In this statement, the SEC’s Division of Trading and Markets and the CFTC’s Divisions of Market Oversight and Clearing & Risk clarify their view that current law does not prohibit SEC-registered national securities exchanges or CFTC-registered exchanges from facilitating trading in these spot crypto commodity products. This cross-agency initiative-part of the SEC’s “Project Crypto” and the CFTC’s “Crypto Sprint” — is intended to promote trading venue choice for digital assets and encourage crypto market innovation within the U.S. regulatory framework.

• The European Union’s Markets in Crypto Assets Regulation (“MiCA”), a comprehensive digital asset regulatory framework for the issuance and provision of services in relation to digital assets, like AVAX, became effective in June 2023, with various requirements phasing into effect through 2024. MiCA regulates the authorization requirement for and supervision of crypto-asset service providers, as well as crypto-asset issuers, offerors and persons seeking admission to trading of crypto-assets in the European Union. In addition, MiCA also requires the European Commission (i) to provide a report on the environmental impact of crypto-assets and (ii) based upon such report, introduce measures that might be warranted to mitigate the adverse impacts on the environment of technologies employed in markets in crypto-assets like the consensus mechanisms such as mandatory minimum sustainability standards for consensus mechanisms, including the proof-of-stake consensus mechanisms on which the Avalanche blockchain is based.

• Firms engaging in crypto-asset activities in the UK must currently be registered with the Financial Conduct Authority (the “FCA”) under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 (“MLRs”), and are subject to various requirements and obligations as a result. The marketing of crypto-assets is also restricted and the marketing and sale of derivatives and exchange-traded notes that reference certain types of crypto-assets to retail customers in the UK is prohibited, although the FCA now plans to remove the ban on the marketing and sale of exchange-traded notes. The UK regulatory framework for crypto-assets continues to evolve rapidly, and firms operating in this space face an increasingly complex and restrictive compliance landscape. The FSMA 2023 established a framework to bring certain crypto-asset activities, including issuance and trading, within the UK’s financial regulatory perimeter. Detailed rules relating to the regime are still under consultation by His Majesty’s Treasury and the FCA. In April 2025, His Majesty’s Treasury published draft legislation to bring a wide range of crypto-asset activities within the scope of the UK’s regulatory perimeter, including operating a crypto-asset trading venue, providing custody services and dealing in crypto-assets. The FCA is also consulting on various elements of its forthcoming crypto-asset regime, including in respect of the issuance of stablecoins, the custody of crypto-assets and prudential requirements for crypto-asset businesses. The final rules are expected to come into force in phases from late 2025 into 2026; and

• In China, the People’s Bank of China and the National Development and Reform Commission have declared all cryptocurrency transactions illegal within the country. Other jurisdictions, including Egypt, Morocco and the Dominican

55

Republic have also made the use of digital assets illegal. If the use of digital assets is made illegal in other jurisdictions, the available market for AVAX may contract. Additionally, if another government with considerable economic power were to ban digital assets or related activities, this could have further impact on the price of AVAX. As a result, the markets and opportunities discussed herein may not reflect the markets and opportunities available to us in the future.

While the current administration has expressed support regarding the development and use of digital assets and the U.S. enacted the GENIUS Act in July 2025, the specific regulatory frameworks, including the potential adoption of the CLARITY Act, RFIA, DCIA and/or any other digital asset market structure bill are still to be developed. Although in December 2025, the FDIC published a notice of proposed rulemaking that seeks to establish the procedures for institutions under its supervision to obtain an approval to issue payment stablecoins through a subsidiary, this is only the beginning of the first of many rulemakings under the GENIUS Act. The exact timeline and impact of these efforts on our business is uncertain, and there is uncertainty regarding enforcement actions by several U.S. agencies involving digital asset issuers and trading platforms. Additionally, it is not possible to predict whether, or when, any of these developments will lead to Congress granting additional authorities to the SEC or other regulators, or the impact of any such additional authorities, including the authority that Congress has already granted to the banking agencies under the GENIUS Act. It is also not possible to predict how additional legislation, regulation or other form of regulatory or supervisory oversight — such as the implementing regulations under the GENIUS Act or any Senate amendments to the CLARITY Act, RFIA or DCIA — might impact the ability of digital asset markets to function or the willingness of financial and other institutions to continue to provide services to the digital assets industry, nor how any new regulations or changes to existing regulations might impact the value of digital assets generally and AVAX specifically.

We cannot be certain as to how future regulatory developments will impact the treatment of AVAX under the law, and ongoing and future regulation and regulatory actions could significantly restrict or eliminate the market for or uses of AVAX and materially and adversely impact our business. If we fail to comply with such additional regulatory and registration requirements, we may seek to cease certain of our operations or be subjected to fines, penalties and other governmental action. Such circumstances could have a material adverse effect on our ability to continue as a going concern or to pursue our business model at all, which could have a material adverse effect on our business, prospects or operations. The consequences of increased regulation of digital assets and digital asset activities could adversely affect the market price of AVAX and any other digital assets we may hold or expect to hold at such time and in turn adversely affect the market price of Pubco Class A Stock.

Moreover, the risks of engaging in a AVAX acquisition strategy are relatively novel and have created, and could continue to create, complications due to the lack of experience that third parties have with companies engaging in such a strategy, such as increased costs of director and officer liability insurance or the potential inability to obtain such coverage on acceptable terms in the future.

The novelty of AVAX may increase the risk of employee or service provider misconduct or error, which may adversely impact the business of Pubco. Employee or service provider misconduct or error could subject us to legal liability, financial losses and regulatory sanctions and could seriously harm our reputation and negatively affect our business. Such misconduct could include engaging in improper or unauthorized transactions or activities, failing to supervise other employees or service providers, improperly using confidential information, as well as improper trading activity. Employee or service provider errors could expose us to the risk of material losses even if the errors are detected. Moreover, the risk of employee or service provider error or misconduct may be even greater for novel Avalanche-based products and services which we may offer in the future. It is not always possible to deter misconduct, and the precautions we take to prevent and detect this activity may not be effective in all cases. If we were found to have not met our regulatory oversight and compliance and other obligations, we could be subject to regulatory sanctions, financial penalties, restrictions on our activities for failure to properly identify, monitor and respond to potentially problematic activity and seriously damage our reputation. Our employees, or any contractors and agents we may contract with, could also commit errors that subject us to financial claims for negligence, as well as regulatory actions, or result in financial liability. Further, allegations by regulatory or criminal authorities of improper trading activities could affect our brand and reputation.

The growth of the digital assets industry in general, and the use and acceptance of AVAX in particular, are subject to a high degree of uncertainty and may also impact the price of AVAX. The pace of worldwide growth in the adoption and use of AVAX may depend, for instance, on public familiarity with digital assets, ease of buying, accessing or gaining exposure to AVAX, institutional demand for AVAX as an investment asset, the participation of traditional financial institutions in the digital assets industry, consumer demand for AVAX as a means of payment and the availability and popularity of alternatives to AVAX. Even if growth in AVAX adoption occurs in the near or medium-term, there is no assurance that AVAX usage will continue to grow over the long-term. In

56

addition, private actors that are wary of digital assets and blockchains like Avalanche or the regulatory concerns associated with Avalanche and AVAX have in the past taken, and may in the future take, further actions that may have an adverse effect on our business or the market price of Pubco Class A Stock.

Because AVAX has no physical existence beyond the record of transactions on the Avalanche blockchain, a variety of technical factors related to the Avalanche blockchain could also impact the price of AVAX. For example, malicious attacks by validators, inadequate staking fees to incentivize validating of Avalanche transactions, hard “forks” of the Avalanche blockchain into multiple blockchains, and advances in digital computing, algebraic geometry and quantum computing could undercut the integrity of the Avalanche blockchain and negatively affect the price of AVAX. The liquidity of AVAX may also be reduced and damage to the public perception of AVAX may occur, if financial institutions were to deny or limit banking services to businesses that hold AVAX, provide Avalanche-related services or accept AVAX as payment, which could also decrease the price of AVAX. Liquidity of AVAX may also be impacted to the extent that changes in applicable laws and regulatory requirements negatively impact the ability of exchanges and trading venues to provide services for AVAX and other digital assets.

The regulatory environment for digital assets in the United States and globally remains highly uncertain and is evolving rapidly. U.S. policymakers are only beginning to define a comprehensive regulatory framework for digital assets. As a result, Pubco may face challenges in adapting to proposed or newly enacted laws and regulations, which could materially and adversely affect its business, financial condition and operations.

As crypto assets have grown in both popularity and market size, various U.S. federal, state and local and foreign governmental organizations, as well as consumer agencies and public advocacy groups, have increasingly scrutinized the operations of crypto networks, users and platforms, with a focus on how crypto assets can be used to launder the proceeds of illegal activities and fund criminal or terrorist enterprises. In addition, the safety and soundness of platforms and other service providers that hold crypto assets for users have drawn regulatory and public attention. These concerns have led to calls for heightened regulatory oversight, and new laws and regulations.

Unlike traditional financial institutions, which have cultivated long-standing relationships with policymakers and regulators, participants in the crypto-economy are relatively new to the U.S. legislative and regulatory landscape. While engagement with policymakers and regulators has begun, it is still at a relatively nascent stage and may be insufficient to influence future legislation and regulation. As a result, new laws and regulations may be proposed and adopted in the United States and internationally, or existing laws and regulations may be interpreted in new ways, that adversely affect the crypto-economy or crypto asset platforms. Consequently, Pubco may be disproportionately impacted by such developments, potentially restricting its ability to operate or innovate. Additionally, any future political activities to further our mission may be perceived unfavorably by investors and the public and have an adverse impact on our brand and reputation.

As also noted above, there has been increasing focus on the extent to which digital assets can be used to launder the proceeds of illicit activities, fund criminal or terrorist activities, or circumvent sanctions regimes, including those sanctions imposed in response to ongoing war between Russia and Ukraine. If we are found to have purchased any of our AVAX from bad actors that have used AVAX to launder money or persons subject to sanctions, we may be subject to regulatory proceedings and any further transactions or dealings in AVAX by us may be restricted or prohibited.

Additional laws, guidance and policies may be issued by domestic and foreign regulators following the bankruptcy of FTX Trading Ltd., one of the world’s largest cryptocurrency exchanges, in November 2022, which has been widely cited as a catalyst for increased regulatory and enforcement focus on the digital assets industry and certain market participants and practices. Increased enforcement activity and changes in the regulatory environment, including changing interpretations and the implementation of new or varying regulatory requirements by the government or any new legislation affecting AVAX, as well as enforcement actions involving or impacting our trading venues, counterparties and custodians, may impose significant compliance and other costs on Pubco, significantly limit our ability to hold and transact in AVAX or materially reduce the value of Pubco’s AVAX holdings.

57

AVAX’s status as a product that may be offered and sold as a “security” in any relevant jurisdiction, as well as the status of Avalanche-related products, and services in general, is subject to uncertainty, and if Pubco is unable to properly characterize such product or service offering, Pubco may be subject to regulatory scrutiny, inquiries, investigations, fines and other penalties, which may adversely affect Pubco’s business, operating results and financial condition.

The SEC and its staff have taken the position that a range of crypto assets, products and services fall within the definition of an investment contract that is offered or sold as a “security” under the U.S. federal securities laws. The legal test for determining whether any given crypto asset, product or service that is offered and sold is an investment contract was set forth in the 1946 U.S. Supreme Court case SEC v. W.J. Howey Co. and requires a fact-intensive analysis. Accordingly, whether any given crypto asset, product or service that would be ultimately deemed to be offered and sold is a “security” is uncertain and difficult to predict notwithstanding the conclusions of the SEC or any conclusions we may draw based on our risk-based assessment regarding the likelihood that a particular crypto asset, product or service could be deemed to be offered or sold as a “security” or “securities offering” under applicable laws.

The SEC has not stated or alleged that it believes that AVAX is an investment contract and, therefore, a securities. Even if it is concluded that a crypto asset, in itself, is not a security, the SEC and courts have taken the position that a crypto asset can be offered and sold in securities transactions, which carries many of the same regulatory risks and consequences summarized above. For example, the SEC has taken the position that yield, lending products, services or protocols can constitute the offer and sale of security even if the underlying crypto asset is not a security.

Any enforcement action by the SEC or any international or state securities regulator asserting that AVAX should be offered and sold as a “security” or a court decision to that effect, or any international or state securities regulator asserting that AVAX itself is a “security”, would be expected to have an immediate material adverse impact on the trading value of AVAX, as well as our business.

Several foreign jurisdictions have taken a broad-based approach to classifying crypto assets, products and services that are being offered or sold as “securities,” while other foreign jurisdictions have adopted a narrower approach. As a result, certain crypto assets, products or services, including those relating to Avalanche, may be deemed to be offered and sold as a “security” under the laws of some jurisdictions but not others. Various foreign jurisdictions may, in the future, adopt additional laws, regulations or directives that affect the characterization of crypto assets, products or services that are offered or sold as “securities.”

The classification of a crypto asset, product or service that is offered and sold as a security under applicable law has wide-ranging implications for the regulatory obligations that flow from the offer, sale, trading and clearing, as applicable, of such assets, products or services. For example, a crypto asset, product or service that is offered and sold as a security in the United States may generally only be offered or sold in the United States pursuant to a registration statement filed with the SEC or in an offering that qualifies for an exemption from registration. Persons that effect transactions in crypto assets, products or services that are offered or sold as securities in the United States may be subject to registration with the SEC as a “broker” or “dealer.” Platforms that bring together purchasers and sellers to trade crypto assets that are offered or sold as securities in the United States are generally subject to registration as national securities exchanges, or must qualify for an exemption, such as by being operated by a registered broker-dealer as an alternative trading system (“ATS”) in compliance with rules for ATSs. Persons facilitating clearing and settlement of securities may be subject to registration with the SEC as a clearing agency. Foreign jurisdictions may have similar licensing, registration and qualification requirements.

In its initial business activities, which will constitute (i) the targeted accumulation of AVAX, (ii) tailored treasury management geared towards staking yield and other asset management levers intended to compound AVAX per share over time and (iii) further ecosystem integration including the potential provision of Avalanche-focused infrastructure, such as the operation of validator nodes, L1 activation and other corporate development activities, Pubco does not plan to offer or sell AVAX as “investment contracts” or otherwise as a “security”. Pubco is not registered or licensed with the SEC or foreign authorities as a broker-dealer, national securities exchange or ATS (or foreign equivalents), and we believe that AVAX in itself or as a result of the manner in which we intend to purchase or sell AVAX in our initial business activities, is not a security (including based on prior statements by a number of SEC senior officials). However, statements, settlements and enforcement actions are not rules or regulations of the SEC and are not binding on the SEC. Regardless of public statements made by senior officials at the SEC and our conclusions, we could in the future be subject to legal or regulatory action in the event the SEC or a state or a foreign regulatory authority were to assert, or a court were to determine, that either AVAX itself or a product or service that we may offer or sell in the future related to Avalanche could be viewed a “security” under applicable laws. There can be no assurance that we will properly characterize over time any given Avalanche product or service that is offered and sold as a security or non-security, or that the SEC, foreign regulatory authority or a court having

58

final determinative authority on the topic, if the question was presented to it, would agree with our assessment. We expect our risk assessment policies and procedures to continuously evolve to take into account case law, legislative developments, facts and developments in technology.

If an applicable regulatory authority or a court, in either case having final determinative authority on the topic, were to determine that a product or service that is offered or sold by us in the future is a security, we would not be able to offer such product or service until we are able to do so in a legally compliant manner. A determination by the SEC, a state or foreign regulatory authority, or a court that a product or service that is offered or sold constitutes a security may result in us ceasing to offer that product or service, and may also result in us determining that it is advisable to cease offering products and services entirely, that have similar characteristics to the product or service that was alleged or determined to be a security. Alternatively, we may determine to continue to offer certain future products or services even if the SEC or another regulator alleges that the product or service is offered or sold as a security, pending a final judicial determination as to that product or service’s proper characterization, and the fact that we waited for a final judicial determination would generally not preclude penalties or sanctions against us for our having previously made that product or service available without registering that product or service with the SEC. As such, we could be subject to judicial or administrative sanctions for failing to offer or sell the product or service in compliance with the registration requirements, or for acting as a broker, dealer or national securities exchange without appropriate registration. Such an action could result in injunctions, cease and desist orders, as well as civil monetary penalties, fines and disgorgement, criminal liability, and reputational harm. Additionally, the SEC has brought and may in the future bring enforcement actions against other crypto-economy participants and their product offerings and services that may cause us to modify or discontinue a product offering or service. If we were to modify or discontinue any future product offering or service for any reason, our decision may be unpopular with users, may reduce our ability to attract and retain customers (especially if similar products or services continue to be offered by our competitors), and may adversely affect our business, operating results and financial condition. Additionally, if AVAX were to be categorized as a security it may have adverse consequences for the market for AVAX, including an adverse impact on liquidity.

Regulatory changes classifying AVAX as a “security” could lead to Pubco’s classification as an “investment company” under the Investment Company Act and could adversely affect the market price of AVAX and the market price of shares of Pubco Class A Stock.

While the SEC has not called AVAX a “security” for purposes of the U.S. federal securities laws, a contrary determination by the SEC could lead to our classification as an “investment company” under the Investment Company Act, which would subject us to significant additional regulatory controls that could have a material adverse effect on our business and operations and may also require us to substantially change the manner in which we conduct our business.

In addition, if AVAX is determined to constitute a security for purposes of the federal securities laws, the additional regulatory restrictions imposed by such a determination could adversely affect the market price of AVAX as well as the ability to buy and sell it and in turn adversely affect the market price of shares of Pubco Class A Stock. For additional information on the additional requirements we would be required to meet if we were determined to be an investment company, see “If MLAC is deemed to be an investment company under the Investment Company Act, MLAC may be required to institute burdensome compliance requirements and its activities may be restricted, which may make it difficult for MLAC to complete the Business Combination.”

Pubco will not be subject to the same legal and regulatory obligations, including certain compliance and reporting obligations intended to protect investors, that apply to investment companies such as mutual funds and ETFs, or to obligations applicable to investment advisers.

Mutual funds, ETFs and their directors and management are subject to extensive regulation as “investment companies” and “investment advisers” under U.S. federal and state law; this regulation is intended for the benefit and protection of investors.

We believe we are currently not subject to, and subsequent to the Business Combination, will not be subject to, and do not otherwise voluntarily comply with, these laws and regulations. Consequently, shareholders of Pubco do not have the regulatory protections provided to shareholders in registered and regulated investment companies, which, for example, require investment companies to have a certain percentage of disinterested directors and regulate the relationship between the investment company and certain of its affiliates. Further, Pubco may hold or trade in commodity futures contracts in order to hedge its AVAX holdings. A futures contract, which is a type of derivative, is subject to the risk of loss caused by unanticipated market movements, which are potentially unlimited. In addition, there may at times be an imperfect correlation between the movement in the prices of futures

59

contracts and the value of their underlying instruments or indexes, and there may at times not be a liquid secondary market for certain futures contracts leading to the possible inability to sell or close out a futures contract at the desired time or price. Commodity futures are regulated by the Commodity Exchange Act, as administered by the CFTC. We do not believe that we are a commodity pool for purposes of the Commodity Exchange Act. Consequently, shareholders will not have the regulatory protections provided to shareholders in Commodity Exchange Act- regulated instruments or commodity pools. However, the CLARITY Act would amend the CEA to add spot digital commodities to the definition of commodity interests, which could cause the company to be deemed a commodity pool or commodity pool operator and subject the company to additional regulatory requirements and compliance burdens.

This means, among other things, that the execution of or changes to our AVAX acquisition and management strategy, our use of leverage, the manner in which our AVAX is custodied, our ability to engage in transactions with affiliated parties and our operating and investment activities generally are not subject to the extensive legal and regulatory requirements and prohibitions that apply to investment companies and investment advisers. For example, although a significant change to our AVAX acquisition strategy would require the approval of the Pubco Board, no shareholder or regulatory approval would be necessary. Consequently, the Pubco Board has broad discretion over the investment, leverage and cash management policies it authorizes, whether in respect of our AVAX holdings or other activities we may pursue, and has the power to change our current policies, including our strategy of acquiring and holding AVAX.

Pubco is subject to laws, regulations, and executive orders regarding economic and trade sanctions, anti-bribery, AML, and counter-terrorism financing that could impair our ability to compete in international markets or subject us to criminal or civil liability if we violate them. As Pubco continues to expand and localize its international activities, its obligations to comply with the laws, rules, regulations, and policies of a variety of jurisdictions will increase and we may be subject to investigations and enforcement actions by U.S. and non-U.S. regulators and governmental authorities.

As Pubco expands, it has and will become increasingly obligated to comply with the laws, rules, regulations, policies, and legal interpretations both of the jurisdictions in which it operates and those into which it offers services on a cross-border basis. Laws regulating financial services, the internet, mobile technologies, digital assets, and related technologies outside the United States often impose different, more specific, or even conflicting obligations on us, as well as broader liability.

Pubco is required to comply with applicable U.S. economic and trade sanctions administered by the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”), as well as similar requirements in other jurisdictions. The OFAC regulations and requirements generally restrict dealings by persons subject to U.S. jurisdiction with certain countries, or subnational territories that are the target of comprehensive sanctions, which currently are Cuba, Iran, and North Korea, as well as Crimea, the so-called Donetsk People’s Republic, and the so-called Luhansk People’s Republic regions of Ukraine. In addition, OFAC restricts dealings by persons subject to U.S. jurisdiction with specific individuals and entities that are the subject of targeted sanctions, including persons identified on blocked persons lists.

Pubco is also subject to various AML and counter-terrorism financing laws and regulations around the world that prohibit, among other things, our involvement in transferring the proceeds of criminal activities. In the United States, many of our activities are subject to AML laws and regulations, including the Bank Secrecy Act of 1970 (the “BSA”) and other similar laws and regulations. The BSA, among other things, requires money transmitters to develop and implement risk-based AML programs; to report large cash transactions and suspicious activity; and, in some cases, to collect and maintain information about customers who use their services and maintain other transaction records. Regulators in the United States and globally continue to increase their scrutiny of compliance with these obligations, which may require us to further revise or expand our compliance program, including the procedures we use to verify the identity of our customers and to monitor transactions on our system, which would include payments to persons outside the United States. Regulators regularly reexamine the transaction volume thresholds at which we must obtain and keep applicable records or verify identities of customers. Any change in such thresholds could result in greater costs for compliance. We also could be subject to potentially significant fines, penalties, inquiries, audits, investigations, enforcement actions, and criminal and civil liability if regulators or third-party auditors identify gaps in our AML program that are not sufficiently remediated, or if our AML program is found to violate the BSA.

Despite our efforts to comply with applicable laws and regulations, there can be no guarantee that regulators and/or law enforcement will view these measures as compliant with the BSA or U.S. sanctions laws and regulations. If regulators and/or law enforcement find that we have violated the BSA or U.S. sanctions laws and regulations, or we are otherwise the subject of government investigations for alleged violations of the BSA or U.S. sanctions laws and regulations, such investigations and alleged violations

60

could result in negative consequences for us, including costs related to government investigations, financial penalties, and harm to our reputation. The impact on us related to these matters could be substantial. Although we have implemented controls and screening tools designed to prevent violative activity, there is no guarantee that we will not inadvertently provide our products and services to individuals, entities, or governments in violation of the BSA or U.S. sanctions laws and regulations.

Regulators worldwide frequently study each other’s approaches to the regulation of the blockchain technology and digital assets. Consequently, developments in any jurisdiction may influence other jurisdictions. Further, new developments in one jurisdiction may be extended to additional services and other jurisdictions. As a result, the risks created by any new law or regulation in one jurisdiction are magnified by the potential that they may be replicated in another jurisdiction, which in turn would affect our business across multiple jurisdictions and/or across our services and products. Conversely, if regulations diverge worldwide, we may face difficulty adjusting our products, services, and other aspects of our business with the same effect. These risks are heightened as we face increased competitive pressure from other similarly situated businesses that engage in regulatory arbitrage to avoid the compliance costs associated with regulatory changes.

We may operate our business in foreign countries where companies often engage in business practices that are prohibited by the U.S. and other jurisdictions’ regulations applicable to us. We are subject to anti- corruption laws and regulations, including the U.S. Foreign Corrupt Practices Act of 1977 (the “FCPA”) and other laws that prohibit the making or offering of improper payments to foreign government officials and political figures, including anti-bribery provisions enforced by the U.S. Department of Justice and the SEC. The FCPA, for example, prohibits U.S. persons and entities from making improper payments or offers of payments to foreign governments and their officials and political parties by the United States and other business entities for the purpose of obtaining or retaining business. We have implemented policies, procedures, systems, and controls designed to identify and address potentially impermissible transactions under such laws and regulations. However, there can be no assurance that all of our employees, consultants, and agents — including those that may be based in or from countries where practices that violate U.S. or other laws may be customary — will not take actions in violation of our policies, for which we may be ultimately responsible.

The complexity of U.S. federal and state and international regulatory and enforcement regimes, coupled with the global scope of our operations and the evolving global regulatory environment, could result in a single event prompting a large number of overlapping investigations and proceedings by multiple government authorities in different jurisdictions. Furthermore, due to the uncertain application of existing laws and regulations, it may be that, despite our regulatory and legal analysis concluding that certain products and services are currently unregulated or fit within a particular category of regulatory activities, such products or services may indeed be subject to financial regulation, licensing, or authorization obligations that we have not obtained or with which we have not complied. As a result, we are at a heightened risk of enforcement action, litigation, and regulatory and legal scrutiny, which could lead to sanctions, cease-and- desist orders, or other penalties and censures. Any of the foregoing could, individually or in the aggregate, have a material adverse effect on our business, results of operations, financial condition, and prospects.

Investment vehicles that pool money for the purpose of trading in commodity interests, which include futures, swaps, options and leveraged transactions, may be required under the Commodity Exchange Act to register as commodity pool operators. Pubco does not intend to engage in such transactions and, accordingly, we do not believe that we are a commodity pool or commodity pool operator for the purposes of the Commodity Exchange Act. The CLARITY Act and DCIA would both amend the CEA to add spot digital commodities to the definition of commodity interests, which could cause the company to be deemed a commodity pool or commodity pool operator and subject the company to additional regulatory requirements and compliance burdens.

Due to the unregulated nature and lack of transparency surrounding the operations of many AVAX trading venues, AVAX trading venues may experience greater fraud, security failures or regulatory or operational problems than trading venues for more established asset classes, which may result in a loss of confidence in AVAX trading venues and adversely affect the value of Pubco’s AVAX holdings.

AVAX trading venues are relatively new and, in many cases, unregulated. Furthermore, there are many AVAX trading venues which do not provide the public with significant information regarding their ownership structure, management teams, corporate practices and regulatory compliance. As a result, in the event one or more AVAX trading venues cease or pause for a prolonged period the trading of AVAX or other digital assets, or experience fraud, significant volumes of withdrawal, security failures or operational problems, the marketplace may lose confidence in AVAX trading venues, including prominent exchanges that handle a significant volume of AVAX trading and/or are subject to regulatory oversight.

61

The SEC has also brought actions against individuals and digital asset market participants alleging such persons artificially increased trading volumes in certain digital assets through wash trades, or repeated buying and selling of the same assets in fictitious transactions to manipulate their underlying trading price. Such reports and allegations may indicate that the digital assets markets are significantly smaller than expected and that the United States makes up a significantly larger percentage of the digital assets markets than is commonly understood. Any actual or perceived false trading in the digital asset markets, and any other fraudulent or manipulative acts and practices, could adversely affect the value of our AVAX. Negative perception, a lack of stability in the broader digital asset markets and the closure, temporary shutdown or operational disruption of AVAX trading venues, lending institutions, institutional investors, institutional validators, custodians or other major participants in the Avalanche ecosystem, due to fraud, business failure, cybersecurity events, government-mandated regulation, bankruptcy, or for any other reason, may result in a decline in confidence in AVAX and the broader AVAX ecosystem and greater volatility in the price of AVAX. For example, in 2022, each of Celsius Network, Voyager Digital, Three Arrows Capital, FTX Trading Ltd., and BlockFi filed for bankruptcy, following which the market prices of certain digital assets significantly declined. The SEC also alleged as part of its June 5, 2023, complaint that Binance Holdings Ltd. committed strategic and targeted “wash trading” through its affiliates to artificially inflate the volume of certain digital assets traded on its exchange. In addition, in June 2023, the SEC announced enforcement actions against Coinbase, Inc., and Binance Holdings Ltd., two providers of large trading venues for digital assets, which similarly was followed by a decrease in the market price of certain digital assets. These were followed in November 2023, by an SEC enforcement action against Payward Inc. and Payward Ventures Inc., together known as Kraken, another large trading venue for digital assets. While the current U.S. administration has dismissed these enforcement actions, it is uncertain when or whether new enforcement actions may be brought. The price of Pubco Class A Stock may be affected by the value of our AVAX holdings and the failure of a major participant in the Avalanche ecosystem could have a material adverse effect on the market price of Pubco Stock.

Pubco’s compliance and risk management methods might not be effective and may result in outcomes that could adversely affect Pubco’s reputation, operating results and financial condition.

Our ability to comply with applicable complex and evolving laws, regulations and rules is largely dependent on the establishment, maintenance and scaling of our compliance, internal audit and reporting systems, as well as our ability to attract and retain qualified compliance and other risk management personnel. We cannot assure you that our policies and procedures will always be effective or that we have been and will always be successful in monitoring or evaluating the risks to which we are or may be exposed in all market environments or against all types of risks, including unidentified or unanticipated risks. Our risk management policies and procedures are expected to rely on a combination of technical and human controls and supervision that are subject to error and failure. Some of our methods for managing risk are discretionary by nature and are based on internally developed controls and observed historical market behavior, and also involve reliance on standard industry practices. Accordingly, in the future, we may identify gaps in such policies and procedures or existing gaps may become higher risk, and may require significant resources and management attention. Our risk management policies and procedures also may not adequately prevent losses due to technical errors if our testing and quality control practices are not effective in preventing failures. In addition, we may elect to adjust our risk management policies and procedures to allow for an increase in risk tolerance, which could expose us to the risk of greater losses.

Any potential regulators who may have jurisdiction over us, including in the future, may periodically review our compliance program, including our policies and procedures, and compliance with applicable law. We may from time to time receive examination reports citing violations of applicable law and inadequacies in existing compliance programs requiring us to enhance certain practices with respect to our practices or compliance program, including due diligence, training, monitoring, reporting and recordkeeping. If we fail to comply with these, or do not adequately remediate certain findings, regulators and financial institution partners could take a variety of actions that could impair our ability to conduct our business, including, but not limited to, delaying, denying, withdrawing or conditioning approval of certain products and services. In addition, regulators have broad enforcement powers to censure, fine, issue cease and desist orders that may prohibit us from engaging in some of our business activities, or revoke any licenses we may obtain in the future. We face significant intervention by regulatory authorities, including extensive auditing and surveillance activities, and will continue to face the risk of significant intervention by regulatory authorities and potential future financial institution partners in the future. In the case of non-compliance or alleged non-compliance, we could be subject to investigations and proceedings that may result in substantial penalties or civil lawsuits, including by customers, for damages, which can be a significant loss to us or our financial institution partner(s). Any of these outcomes would adversely affect our reputation and brand and our business, operating results and financial condition. Some of these outcomes could adversely affect our ability to conduct our business.

In the future, we may engage in other Avalanche-related activities and services that are subject to regulation. This could include Avalanche-related debt and equity structured products and Avalanche-related lending activities or the deployment of non-AVAX

62

offering proceeds to acquire additional AVAX in the market. We have not previously engaged in these business lines and we may be unable to implement our business plan, including, without limitation, due to operational challenges, significant competition and regulation. We could also incur indebtedness or enter into other financial instruments in the future that may be collateralized by our AVAX holdings or pursue other strategies to create income streams or otherwise generate funds using our AVAX holdings. These offerings are expected to be highly regulated, and any failure to obtain or maintain necessary money transmission, banking services and/or virtual currency business activity registrations and licenses, or comply with any applicable laws, rules and regulations could adversely affect our ability to offer these services. See “— AVAX’s status as a “security” in any relevant jurisdiction, as well as the status of Avalanche-related products and services in general, is subject to a high degree of uncertainty, and if Pubco is unable to properly characterize such product or service offering, Pubco may be subject to regulatory scrutiny, inquiries, investigations, fines and other penalties, which may adversely affect Pubco’s business, operating results and financial condition.” Regulators and payment processors have historically taken actions relating to access to banking services. Heightened scrutiny by regulators could be detrimental to our long-term strategy and failure to comply with regulators during and after our engagement in such activities could damage our brand, reputation, business, operating results and financial condition.

Further, Pubco has not previously engaged in such Avalanche-related products or services, and may be unable to implement a business strategy to successfully deliver these additional services. We cannot guarantee our success to deliver these services. However, if we fail to keep pace with rapid industry changes to provide new and innovative products and services, and are unable to offer such financial services to generate revenue, this could adversely impact our business, operating results and financial condition. The further development and acceptance of cryptocurrency networks and other cryptocurrency financial services, which represent a new and rapidly changing industry, are subject to a variety of factors that are difficult to predict and evaluate. Conversely, the slowing or stopping of the development or acceptance of digital asset systems may also adversely affect our ability to implement this business strategy.

Even if we are able to expand our future operations, we cannot guarantee that we will convince future customers to use these products or services. If our future customers decrease their level of engagement with our products, services and platform, our business, operating results and financial condition may be significantly harmed.

Pubco may be unable to recognize the economic benefit of a “fork” or an “airdrop”, which could adversely impact an investment in Pubco.

From time to time, Pubco may come into possession of, acquire, or otherwise establish dominion and control over, digital assets or other assets or rights, or be entitled to acquire any of the foregoing, incidental to Pubco’s ownership of AVAX and which arise without any action of Pubco (“Incidental Rights”). Incidental Rights can arise in a number of ways, including a fork in the Avalanche blockchain, or an airdrop to holders of AVAX (each described below). Although Pubco intends to recognize forked and airdropped assets in close cooperation with the approach taken by its partner custodians at the time, Pubco may elect not to take advantage of such Incidental Rights, or may be unable to do so, or may irrevocably abandon the Incidental Rights or other assets, even if this may be economically detrimental to Pubco.

Network Forks.

Avalanche, along with many other blockchain networks, are open-source projects. As a result, any individual can propose modifications or improvements through one or more software upgrades that could alter the protocol layer. In most cases, when a modification is proposed, a substantial majority of validators adopt it, especially if the new version would be incompatible with the then-current version. However, when a substantial majority of validators do not adopt the modified version, the result is a “hard fork” with two incompatible networks and two incompatible digital assets.

Forks can occur for other reasons as well. For example, after a significant security breach, stakeholders on the network could elect to “fork” the network to its state before the hack, effectively reversing the hack. A fork could also be introduced unintentionally through a software bug or network activity.

Significant forks are typically announced several months in advance. The circumstances of each fork are unique, and their relative significance varies. It is possible that a particular fork may result in a significant disruption to Avalanche and, potentially, may result in broader market disruption should pricing become difficult following the fork. It is not possible to predict with accuracy the impact that any anticipated fork could have or for how long any resulting disruption may exist.

63

Forks may have a detrimental effect on the value of AVAX, including by negatively affecting cryptocurrency allocations or by failing to capture of the full value of the newly forked Avalanche if it is excluded from the CME CF ADRR index. Forks can also introduce new security risks. For example, forks may result in “replay attacks,” or attacks in which transactions from one network were rebroadcast to nefarious effect on the other network. After a hard fork, it may become easier for an individual validator or node’s validation power to exceed 50% of the processing power of the digital asset network, thereby making digital assets that rely on proof-of-stake more susceptible to attack. For example, when the Ethereum and Ethereum Classic networks, two other digital asset networks, split in July 2016, replay attacks, in which transactions from one network were rebroadcast to nefarious effect on the other network, plagued Ethereum exchanges through at least October 2016. An Ethereum exchange announced in July 2016 that it had lost 40,000 Ethereum Classic, worth about $100,000 at that time, as a result of replay attacks.

A hard fork may adversely affect the price of AVAX at the time of announcement or adoption. For example, in anticipation that ownership of the pre fork digital asset would entitle holders to a new digital asset following the fork, the announcement of a hard fork could lead to increased demand for the pre-fork digital asset. The increased demand for the pre fork digital asset may cause the price of the digital asset to rise. After the hard fork, it is possible the aggregate price of the two versions of the digital asset running in parallel would be less than the price of the digital asset immediately prior to the fork. While Pubco will determine which network is generally accepted as the Avalanche Network and should therefore be considered the appropriate network for Pubco’s purposes, there is no guarantee that Pubco will choose the network and the associated digital asset that is ultimately the most valuable fork.

In principle, a hard fork could change the source code for the Avalanche Network, including the source code which limits the supply of AVAX to 720 million. Although many observers believe this is unlikely at present, there is no guarantee that the current 720 million supply cap for outstanding AVAX will not be changed. If a hard fork changing the 720 million supply cap is widely adopted, the limit on the supply of AVAX could be lifted, which could have an adverse impact on the value of AVAX and the value of the shares of Pubco Class A Stock.

Unlike other proof-of-stake blockchain networks like Ethereum, where consensus is reached after differences are identified, the Avalanche consensus mechanism is designed such that validators repeatedly sample each other’s opinions pre-emptively, meaning that validators converge on consensus before divergence and ambiguity develop. This difference in consensus mechanic means that unintentional forks are rare on the Avalanche Network as compared to other proof-of-stake networks like Ethereum.

Custodians of Pubco’s AVAX may retain the right to determine whether or not to support (or cease supporting) a forked network. The outcome of such decisions by custodians of Pubco’s AVAX may impact the price of Pubco Class A Stock.

Airdrops.

Owners of AVAX may also become subject to “airdrops.” In an airdrop, the promotors of a different digital asset, typically one that is newly launched, will send that digital asset to the wallet of holders of an existing digital asset for no charge. Airdrops are not always announced and while in some cases the wallet owner needs to take a step to “claim” the new digital asset, in other cases, the wallet owner possesses the new digital asset without taking any actions. For example, in March 2017, the promoters of Stellar Lumens announced that anyone that owned Bitcoin as of June 26, 2017, could claim, until August 27, 2017, a certain amount of Stellar Lumens. Pubco may or may not participate in airdrops.

If Pubco notifies a custodian of its AVAX holdings in writing of an upcoming airdrop, such custodian may, among other actions, elect to: (i) custody the airdropped digital asset for an additional fee or (ii) not pursue obtaining the airdropped digital assets. The outcome of such decisions by custodians may impact the price of Pubco Class A Stock.

In the ordinary course of business managing its AVAX holding as an AVAX treasury company, Pubco may purchase AVAX through spot markets which may be exposed to fraud and market manipulation, including through front running and wash trading, which may adversely affect the value of the shares of Pubco Class A Stock.

The blockchain infrastructure could be used by certain market participants to exploit arbitrage opportunities through schemes such as front-running, spoofing, pump-and-dump and fraud across different systems, platforms or geographic locations. As a result of reduced oversight, these schemes may be more prevalent in digital asset markets than in the general market for financial products.

64

The SEC has identified possible sources of fraud and manipulation in the digital asset market generally, including, among others (1) ”wash trading”; (2) persons with a dominant position in a digital asset like AVAX manipulating AVAX pricing; (3) hacking of the digital asset network and trading platforms; (4) malicious control of the digital asset network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in the specified digital asset, new sources of demand for the specified digital asset, etc.) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported “stablecoins,”; and (7) fraud and manipulation at digital asset trading platforms.

In the ordinary course of business managing its AVAX holding as an AVAX treasury company, Pubco may purchase AVAX through spot markets. Over the past several years, a number of digital asset spot markets have been closed or faced issues due to fraud. In many of these instances, the customers of such digital asset spot markets were not compensated or made whole for the partial or complete losses of their account balances in such exchanges.

Academics and market observers have put forth evidence to support claims that manipulative trading activity has occurred on certain digital asset exchanges. For example, in a 2017 paper entitled “Price Manipulation in the Bitcoin Ecosystem” sponsored by the Interdisciplinary Cyber Research Center at Tel Aviv University, a group of researchers used publicly available trading data, as well as leaked transaction data from a 2014 Mt. Gox security breach, to identify and analyze the impact of “suspicious trading activity” on Mt. Gox between February and November 2013, which, according to the authors, caused the price of Bitcoin to increase from around $150 to more than $1,000 over a two-month period. In August 2017, it was reported that a trader or group of traders nicknamed “Spoofy” was placing large orders on Bitfinex without actually executing them, presumably in order to influence other investors into buying or selling by creating a false appearance that greater demand existed in the market. In December 2017, an anonymous blogger (publishing under the pseudonym Bitfinex’d) cited publicly available trading data to support his or her claim that a trading bot nicknamed “Picasso” was pursuing a paint-the-tape-style manipulation strategy by buying and selling Bitcoin and Bitcoin Cash between affiliated accounts in order to create the appearance of substantial trading activity and thereby influencing the price of such assets.

The potential consequences of a spot market’s failure or failure to prevent market manipulation could adversely affect the value of the shares of Pubco Class A Stock. Any market abuse, and a loss of investor confidence in AVAX, may adversely impact pricing trends in digital asset markets broadly, as well as an investment in shares of Pubco Class A Stock.

The price of AVAX on available spot markets may be exposed to wash trading.

Spot markets on which AVAX trades, through which Pubco may purchase AVAX, may be susceptible to wash trading. Wash trading occurs when offsetting trades are entered into for other than bona fide reasons, such as the desire to inflate reported trading volumes. Wash trading may be motivated by non-economic reasons, such as a desire for increased visibility on popular websites that monitor markets for digital assets so as to improve their attractiveness to investors who look for maximum liquidity, or it may be motivated by the ability to attract listing fees from token issuers who seek the most liquid and high-volume exchanges on which to list their coins. Results of wash trading may include unexpected obstacles to trade and erroneous investment decisions based on false information.

Even in the United States, there have been allegations of wash trading even on regulated venues. Any actual or perceived false trading in the digital asset exchange market, and any other fraudulent or manipulative acts and practices, could adversely affect the value of AVAX and/or negatively affect the market perception of AVAX.

To the extent that wash trading either occurs or appears to occur in spot markets on which AVAX trades, investors may develop negative perceptions about AVAX and the digital assets industry more broadly, which could adversely impact the price of AVAX and, therefore, the price of shares of Pubco Class A Stock. Wash trading also may place more legitimate digital asset exchanges at a relative competitive disadvantage.

The price of AVAX on available spot markets may be exposed to front-running.

Spot markets on which AVAX trades, through which Pubco may purchase AVAX, may be susceptible to “front-running,” which refers to the process when someone uses technology or market advantage to get prior knowledge of upcoming transactions. Front-running is a frequent activity on centralized as well as decentralized exchanges. By using bots functioning on a millisecond-scale

65

timeframe, bad actors are able to take advantage of the forthcoming price movement and make economic gains at the cost of those who had introduced these transactions. The objective of a front runner is to buy a chunk of tokens at a low price and later sell them at a higher price while simultaneously exiting the position. Front-running happens via manipulations of gas prices or timestamps, also known as slow matching. To the extent that front-running occurs, it may result in investor frustrations and concerns as to the price integrity of digital asset exchanges and digital assets more generally.

If the digital asset award or transaction fees for recording transactions on the Avalanche Network are not sufficiently high to incentivize validators, such validators may demand high transaction fees, which could negatively impact the value of AVAX and the value of the Pubco Class A Stock.

During the course of the block validation processes, validators exercise the discretion to select which transactions to include within a block and in what order to include these transactions. Beyond the standard block reward and transaction fees, validators have the ability to extract what is known as maximal extractable value (“MEV”) by strategically choosing, reordering or excluding certain transactions during block production in return for increased transaction fees or other forms of revenue for such validators. In blockchain networks that facilitate DeFi protocols in particular, such as the Avalanche Network, users may attempt to gain an advantage over other users by offering additional fees to validators for effecting the order or inclusions of transactions within a block. Certain software solutions, such as MEV Boost by Flashbots, have been developed which facilitate validators and other parties in the ecosystem in capturing MEV. The presence of MEV may incentivize associated practices such as sandwich attacks or front running that can have negative repercussions on DeFi users. A “sandwich attack” is executed by placing two transactions around a large, detected transaction to capitalize on the expected price impact. For instance, a market participant might identify a sizable transaction within the publicly visible memory pool (“mempool”) that will significantly alter an asset’s price on a decentralized exchange. The participant could then, for example, orchestrate a transaction bundle: one transaction to acquire the asset prior to the detected transaction, followed by the large transaction itself, and a final transaction to sell the asset after the market price has increased due to the large transaction’s execution. Such transaction bundles can be submitted to validators through mechanisms like MEV Boost, with validators receiving a share of the profits as an incentive to include the specific transaction bundle in the block. In the context of MEV, “front running” is said to occur when a user spots a transaction in the mempool of pending but unexecuted transactions awaiting validation, and then pays a high transaction fee to a validator to have their transaction executed on a priority basis in a manner designed to profit from the pending but unexecuted transaction that is still in the mempool. MEV may also compromise the predictability of transaction execution, which may deter usage of the network as a whole. Although based on widely available information given that transactions in the mempool are publicly visible, any potential perception of MEV as unfair manipulation may also discourage users and other stakeholders from engaging with DeFi protocols or the Avalanche Network in general. In addition, it is possible regulators or legislators could enact rules that restrict practices associated with MEV, which could diminish the popularity of the Avalanche Network among users and validators.

With respect to the Company’s direct staking activities, the Company’s third-party node operators do not participate in MEV extraction strategies as directed by the Company. Furthermore, staking rewards on the Avalanche Network are determined at the inception of each staking period based on protocol-defined parameters, including the amount staked and the duration of the staking term. As the Company’s node operators do not currently engage in MEV practices, and rewards are locked at inception, the Company’s direct staking returns are not currently directly affected by MEV extraction or other validator-level transaction ordering practices.

With respect to the Company’s liquid staking activities, the Company participates in both the BENQI Protocol, which issues sAVAX, and the Hypha Protocol, which issues stAVAX. stAVAX, is a liquid staking token that represents a pooled claim on staked AVAX and accumulated rewards across a set of validators selected by the liquid staking protocol operator. Unlike the Company’s direct staking arrangements, where rewards are locked at inception and the node operators do not participate in MEV, the value of stAVAX accrues over time based on the ongoing performance of the underlying validator pool, exposing the Company to MEV-related risks that it cannot independently monitor or mitigate. sAVAX is also a liquid staking token that represents a pooled claim on staked AVAX and accumulated rewards across as set of validators selected by the liquid staking protocol operator. These sAVAX do not participate in MEV operations.

66

The liquid staking protocol operator determines which validators receive delegations from the pool, and the Company has no ability to influence validator selection, removal or MEV policies within the protocol. If validators in the underlying pool engage in MEV extraction, the Company’s exposure may be enhanced through the following risks:

● Reward Variability. Validators that participate in MEV may generate outsized returns during periods of high network congestion or DeFi activity, but may underperform during periods of lower MEV opportunity. Because the stAVAX exchange rate reflects the blended performance of all validators in the pool, the Company’s effective yield may fluctuate based on the MEV activity of validators it did not select and cannot remove.

● Penalty Risk. The Avalanche Network does not currently impose slashing penalties on validators. However, validators that fail to meet uptime or performance requirements may become ineligible to earn staking rewards during periods of non-compliance, which would reduce the total rewards accruing to the pool and impair the stAVAX exchange rate.

● Protocol or Reputational Risk. MEV-related controversies involving validators in the underlying pool could erode market confidence in the liquid staking protocol itself, even if the protocol operator is not directly responsible for a validator’s MEV activity. A loss of confidence could cause the market price of stAVAX to trade at a sustained discount to its theoretical redemption value or reduce liquidity in secondary markets for stAVAX.

● Lack of Transparency. The Company has limited visibility into the MEV practices of individual validators within the liquid staking pool. Validators are not required to disclose whether or to what extent they engage in MEV extraction, and the liquid staking protocol operator may not monitor or report on validator-level MEV activity. As a result, the Company may be unable to assess its exposure to MEV-related risks within its stAVAX holdings until after an adverse event has occurred.

Any of these or other outcomes related to MEV may adversely affect the value of AVAX and the value of the shares of Pubco Class A Stock.

Although Pubco will have relevant due diligence procedures at Closing regarding anti-money laundering (“AML”) and know-your-customer (“KYC”), these procedures may fail to prevent illegal transactions, which could subject Pubco to criminal and civil liabilities and impact the value of the shares of Pubco Class A Stock.

Although transaction details of peer-to-peer transactions are recorded on the Avalanche blockchain, a buyer or seller of digital assets on a peer-to-peer basis directly on the Avalanche Network may never know to whom the public key belongs or the true identity of the party with whom it is transacting. Public key addresses are randomized sequences of alphanumeric characters that, standing alone, do not provide sufficient information to identify users. In addition, certain technologies may obscure the origin or chain of custody of digital assets. The opaque nature of the market poses asset verification challenges for market participants, regulators and auditors and gives rise to an increased risk of manipulation and fraud, including the potential for Ponzi schemes, bucket shops and pump and dump schemes. Digital assets have in the past been used to facilitate illicit activities. If a digital asset was used to facilitate illicit activities, businesses that facilitate transactions in such digital assets could be at increased risk of potential criminal or civil lawsuits, or of having banking or other services cut off, and such digital asset could be removed from digital asset exchanges. Any of the aforementioned occurrences could adversely affect the price of the relevant digital asset, the attractiveness of the respective blockchain network and an investment in shares of Pubco Class A Stock. If Pubco were to transact with a sanctioned entity, we would be at risk of potential criminal or civil lawsuits or liability.

Pubco aims to take measures with the objective of reducing illicit financing risks in connection with our activities. However, illicit financing risks are present in the digital asset markets, including markets for AVAX. There can be no assurance that the measures employed by Pubco will prove successful in reducing illicit financing risks, and Pubco will be subject to the complex illicit financing risks and vulnerabilities present in the digital asset markets. If such risks eventuate, Pubco could face civil or criminal liability, fines, penalties, or other punishments, be subject to investigation, have our assets frozen, lose access to banking services or services provided by other service providers, or suffer disruptions to their operations, any of which could negatively affect Pubco’s ability to operate or cause losses in value of the shares of Pubco Class A Stock.

At Closing, Pubco will have adopted and implemented policies and procedures that are designed to ensure that Pubco does not violate applicable AML and sanctions laws and regulations and complies with any applicable KYC laws and regulations. Pubco aims to only interact with known authorized third-party service providers with respect to whom it has engaged in a due diligence process to ensure a thorough KYC process.

67

There is no guarantee that such procedures will always be effective. If third parties have inadequate policies, procedures and controls for complying with applicable anti-money laundering and applicable sanctions laws or Pubco’s diligence is ineffective, violations of such laws could result, which could result in regulatory liability for Pubco under such laws, including governmental fines, penalties, and other punishments, as well as potential liability to or cessation of services by a custodian. Any of the foregoing could impact the value of the shares of Pubco Class A Stock or negatively affect Pubco’s ability to operate.

Risks Related to Being a Public Company

The market price of Pubco Class A Stock may be volatile and decline materially as a result of volatility in AVAX or the digital asset markets generally, or for other reasons. You should be aware that you may lose some or all of your investment.

The trading price of Pubco Class A Stock following completion of the Business Combination is likely to be volatile. The stock market has recently experienced and in the future may experience extreme volatility. This volatility has often been unrelated or disproportionate to the operating performance of particular companies. You may not be able to resell your shares of Pubco Class A Stock at an attractive price due to a number of factors such as the following:

• Pubco’s operating and financial performance and prospects;

• risk of Pubco’s credit rating being downgraded;

• Pubco’s quarterly or annual earnings or those of other companies in its industry compared to market expectations;

• conditions that impact demand for Pubco’s future products and/or services;

• future announcements concerning Pubco’s business, its customers’ businesses or its competitors’ businesses;

• the public’s reaction to Pubco’s press releases or other public announcements and filings with the SEC;

• the market’s reaction to Pubco’s reduced disclosure and other requirements as a result of being an “emerging growth company” under the JOBS Act;

• the size of Pubco’s public float;

• volatility in AVAX, Pubco’s principal asset;

• the control by Seller over Pubco, which results in Pubco being expected to qualify as a “controlled company” under securities exchange rules, and may create conflicts of interest between Pubco and Seller;

• coverage by or changes in financial estimates by securities analysts or failure to meet their expectations;

• market and industry perception of Pubco’s success, or lack thereof, in pursuing its strategy;

• strategic actions by Pubco or its competitors, such as acquisitions or restructurings;

• changes in laws or regulations which adversely affect Pubco’s industry or Pubco;

• privacy and data protection laws, privacy or data breaches, or the loss of data;

• changes in Pubco’s accounting standards, policies, guidance, interpretations or principles;

• changes in Pubco’s senior management or key personnel;

• issuances, exchanges or sales, or expected issuances, exchanges or sales of Pubco Class A Stock;

68

• changes in Pubco’s dividend policy;

• the lack of voting rights;

• failure by Pubco to comply with regulatory requirements, including those related to governance and control requirements in particular jurisdictions, international sanctions or a change in regulations or enforcement policies that adversely affects our operations;

• adverse resolution of any new or pending investigation, regulatory action or litigation against Pubco; and

• changes in general market, economic and political conditions in the United States and other global economies or financial markets, including those resulting from inflation and related monetary policy in response to inflation, natural disasters, terrorist attacks, acts of war and responses to such events.

Broad market and industry factors may materially reduce the market price of Pubco Class A Stock, regardless of Pubco’s operating performance. In addition, price volatility may be greater if the public float and trading volume of Pubco Class A Stock is low. As a result, you may suffer a loss on your investment.

Pubco’s share price may be exposed to additional risks because our business will become a public company through a “de-SPAC” transaction. There has been increased focus by government agencies on such transactions, and Pubco expects that increased focus to continue. Pubco may be subject to increased scrutiny by the SEC and other government agencies on holders of Pubco securities as a result, which could adversely affect the price of Pubco Class A Stock.

A substantial part of Pubco’s assets following the Business Combination will be its AVAX holdings and cash and cash equivalents from the proceeds of the Transactions not invested in AVAX. Although Pubco is expected to have certain other operations, Pubco will depend on such retained cash and cash equivalents to pay its debts and other obligations.

Upon consummation of the Business Combination, a substantial part of Pubco’s assets will be its AVAX holdings and AVAX and cash and cash equivalents from the proceeds of the Transactions not invested in AVAX. While Pubco plans to generate revenue through active management of its AVAX holdings, and potentially developing a dedicated platform of external AVAX investment managers, developing and entering into partnerships for Avalanche-related financial and technology infrastructure, these business strategies are subject to risks as described in this section. Pubco’s ability to pay taxes and operating expenses, as well as its debt service obligations in the future, if any, will be largely dependent upon the financial results and cash flows resulting from its business strategies. There can be no assurance that Pubco will generate sufficient cash flow from its activities or that applicable law and contractual restrictions, including negative covenants under any debt instruments, if applicable, will permit the sale of AVAX that secures then- outstanding notes in order to fund working capital needs. Pubco may default on contractual obligations or have to borrow additional funds. In the event that Pubco is required to borrow additional funds, it could adversely affect Pubco’s liquidity and subject it to additional restrictions imposed by lenders. If Pubco enters into additional financing or other agreements in the future, Pubco cannot make assurances that these agreements will be on favorable terms or that they will not restrict the distribution of dividends or other payments to shareholders.

Pubco’s ability to timely raise capital in the future may be limited, or may be unavailable on acceptable terms, if at all. Pubco’s failure to raise capital when needed could harm its business, operating results and financial condition.

Pubco cannot be certain if it will generate sufficient cash through active management of its AVAX holdings. Additional financing may not be available on favorable terms, if at all. If adequate funds are not available on acceptable terms, Pubco may be unable to invest in future growth opportunities, which could harm Pubco’s business, operating results and financial condition. Pubco may from time to time issue convertible notes or preferred stock in order to further its AVAX acquisition strategy. If Pubco incurs debt or issues preferred stock, the debt holders and holders of preferred stock could also have rights senior to holders of Pubco Stock to make claims on Pubco’s assets. The terms of any debt could also restrict Pubco’s operations, including its ability to pay dividends on Pubco Class A Stock. As a result, Pubco shareholders bear the risk of future issuances of debt or preferred securities reducing the value of the shares of Pubco Class A Stock.

69

The issuance of additional shares or convertible securities by Pubco could make it difficult for another company to acquire Pubco, may dilute the ownership of Pubco shareholders and could adversely affect the price of Pubco Class A Stock.

Pubco may obtain additional financing and may, in addition to the Pubco Class A Stock, issue additional shares and/or offer debt or other equity securities, including senior or subordinated notes, debt securities convertible into equity and/or shares of preferred stock. Issuing additional shares of Pubco Stock, other equity securities, and/or securities convertible into equity may dilute the economic and voting rights of Pubco’s existing shareholders, reduce the market price of outstanding shares of Pubco Class A Stock, or both. Securities convertible into equity could be subject to adjustments in the conversion ratio, pursuant to which certain events may increase the number of equity securities issuable upon conversion. Shares of preferred stock could have a preference with respect to liquidating distributions or a preference with respect to dividend payments, including such preferences attached to the preferred stock, that could further limit Pubco’s ability to pay dividends to the holders of Pubco Class A Stock. The potential issuance of additional securities may delay or prevent a change in control of Pubco or the Company, discourage bids for our securities at a premium to the market price, and materially and adversely affect the market price and the voting and other rights of the holders of our securities, including Pubco Class A Stock. Pubco’s decision to issue securities in any future offering will depend on market conditions and other factors beyond its control, which may adversely affect the amount, timing or nature of its future offerings. As a result, holders of Pubco Class A Stock bear the risk that Pubco’s future offerings and exercise of any options under any stock option plans that Pubco may implement may reduce the market price of Pubco Class A Stock and dilute their percentage ownership. See the section entitled “Description of Pubco Securities.”

Future resales of Pubco Class A Stock after the consummation of the Business Combination may cause the market price of Pubco’s securities to drop significantly, even if Pubco’s business is doing well.

The Lock-Up Agreement and the Insider Letter (as will be amended at Closing in accordance with the Sponsor Support Agreement) provide that after the consummation of the Business Combination and subject to certain exceptions, the Pubco Stock received by the Sponsor and Seller will be locked-up and subject to transfer restrictions, as described below, subject to certain exceptions, as described in the section “The Business Combination Proposal — Other Transaction Agreements — Lock-Up Agreement” and “The Business Combination Proposal — Other Transaction Agreements — Sponsor Support Agreement.”

However, following the expiration of such lock-up, the Sponsor and Seller will not be restricted from selling Pubco Stock held by them, other than by applicable securities laws. Upon completion of the Business Combination and assuming that no MLAC Class A Ordinary Shares are redeemed in connection with the Business Combination and based on the other assumptions included elsewhere in this proxy statement/ prospectus, Seller and the Sponsor will collectively beneficially own approximately 20.3% of the outstanding shares of Pubco Class A Stock at Closing. Assuming a maximum redemption of 23,000,000 MLAC Class A Ordinary Shares in connection with the Business Combination, and based on the other assumptions included elsewhere in this proxy statement/prospectus, in the aggregate, the ownership of the Sponsor and Seller would rise to 31.9% of the outstanding shares of Pubco Class A Stock at Closing. These also assume that no shares of Pubco Class A Stock are issued and outstanding under the Incentive Plan or as Adjustment Units pursuant to the Company Unit Subscription Agreements.

In addition, pursuant to the Amended and Restated Registration Rights Agreement, Pubco will agree to register for resale, pursuant to Rule 415 under the Securities Act, shares of Pubco Class A Stock that are held by the Sponsor and Seller. Pursuant to the Amended and Restated Registration Rights Agreement, such parties will have customary registration rights, including demand and piggyback rights. Based on the assumptions included elsewhere in this proxy statement/prospectus, we estimate that up to an aggregate of 15,605,638 shares of Pubco Class A Stock held by such holders will be subject to registration rights following Closing.

As restrictions on resale end and registration statements (filed after the Closing to provide for the resale of such shares from time to time) are available for use, the sale or possibility of sale of these shares could have the effect of increasing the volatility in the market price of Pubco Class A Stock and the market price of Pubco Class A Stock could decline if the holders of currently restricted shares sell them or are perceived by the market as intending to sell them.

70

Pubco will incur significant costs post-Business Combination as a result of being a public company, including additional legal, accounting, insurance and other expenses, as well as costs associated with public company reporting requirements.

Pubco will incur significant legal, accounting, insurance and other expenses, including costs associated with public company reporting requirements following completion of the Business Combination. Pubco will incur significant costs associated with complying with the requirements of the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, and related rules implemented by the SEC and Nasdaq, or any other national securities exchange on which it may list its securities. Pubco expects these laws and regulations to increase its legal and financial compliance costs after the Business Combination and to render some activities more time-consuming and costly, although Pubco is currently unable to estimate these costs with any degree of certainty. Pubco is expected to need to hire more employees post-Business Combination or engage outside consultants to comply with these requirements, which will increase its post-Business Combination costs and expenses. These laws and regulations could make it more difficult or costly for Pubco to obtain certain types of insurance, including directors’ and officers’ liability insurance, and Pubco may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for Pubco to attract and retain qualified persons to serve on the Pubco Board or board committees or as executive officers. Furthermore, if Pubco is unable to satisfy its obligations as a public company, it could be subject to delisting of its Pubco Class A Stock, fines, sanctions and other regulatory action and potentially civil litigation.

Pubco’s management team is expected to have limited experience managing and operating a U.S. public company.

Certain members of Pubco’s management team are expected to have limited experience managing and operating a U.S. publicly traded company, interacting with U.S. public company investors, and complying with the increasingly complex laws pertaining to U.S. public companies. Its transition to being a U.S. public company subjects Pubco to significant regulatory oversight and reporting obligations under the U.S. federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents will require significant attention from Pubco’s senior management and could divert their attention away from the day-to-day management of its business. Pubco may not have adequate personnel with the appropriate level of knowledge, experience and training in the accounting policies, practices or internal control over financial reporting required of U.S. public companies. The development and implementation of the standards and controls necessary for Pubco to achieve the level of accounting standards required of a public company may require costs greater than expected. To support its operations as a U.S. public company, Pubco plans to recruit additional qualified employees or external consultants with relevant experience, which will increase its operating costs in future periods. Should any of these factors materialize, Pubco’s business, financial condition and results of operations could be adversely affected.

If Pubco is unable to maintain an effective system of internal controls and compliances, its business and reputation could be adversely affected.

Pubco plans to manage regulatory compliance by monitoring and evaluating its internal controls to ensure that it is in compliance with all relevant statutory and regulatory requirements, there can be no assurance that deficiencies in its internal controls and compliances will not arise, or that it will be able to implement, and continue to maintain, adequate measures to rectify or mitigate any such deficiencies in its internal controls, in a timely manner or at all. Pubco cannot assure that there will be no instances of inadvertent non-compliances with statutory requirements, which may subject it to regulatory action, including monetary penalties, which may adversely affect its business and reputation.

We have identified a material weakness in our internal control over financial reporting. If remediation of this material weakness is not effective, if we experience additional material weaknesses, or if we otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations.

Effective internal control over financial reporting and disclosure controls and procedures are critical to our success as a public company. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with applicable accounting principles. Similarly, disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosure.

71

In connection with the audit of our financial statements as of December 31, 2025, we identified a material weakness as defined under the Exchange Act, and by the PCAOB in internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis. We identified a material weakness in that we did not design and maintain effective controls over the financial reporting process, including segregation of duties related to journal entries and account reconciliations. We are working to remediate this material weakness and are taking steps to strengthen our internal control over financial reporting. We plan to hire qualified staff as well as develop and implement formal policies, processes and documentation procedures relating to financial reporting, including the oversight of third-party service providers.

The actions that we are taking are subject to ongoing executive management review. If we are unable to successfully remediate the material weakness, or if in the future, they identify further material weaknesses in internal controls over financial reporting, we may not detect errors on a timely basis, and financial statements may be materially misstated. We may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting, which could harm our operating results, cause investors to lose confidence in reported financial information and cause the trading price of Pubco Stock to fall. In addition, as a public company, we will be required to file accurate and timely quarterly and annual reports with the SEC under the Exchange Act. Any failure to report our financial results on an accurate and timely basis could result in sanctions, lawsuits, delisting of shares from Nasdaq or other adverse consequences that could materially harm our business. In addition, we could become subject to investigations by Nasdaq, the SEC and other regulatory authorities, and become subject to litigation from investors and stockholders, which could harm our reputation and financial condition, or divert financial and management resources from our core business.

We intend to remediate the material weakness through formalizing and enhancing policies and procedures regarding the financial reporting process to support the effective deployment of management’s directives and control activities. This includes our plan to design and implement control activities in response to the risks posed as a result of the lack of segregation of duties related to journal entries and account reconciliations.

While we will work to remediate the material weakness as quickly and efficiently as possible, we cannot at this time provide an expected timeline in connection with any remediation plan, and our initiatives may not prove to be successful in remediating the material weakness or preventing additional material weaknesses or significant deficiencies in our internal control over financial reporting in the future. These remediation measures may be time consuming and costly, and might place significant demands on our financial and operational resources. In the future, we may identify additional material weaknesses or significant deficiencies in our internal control over financial reporting. In addition, our current internal control over financial reporting and disclosure controls and procedures, and any new internal control over financial reporting and disclosure controls and procedures that we develop, may become inadequate because of changes in our business, operations and other factors, some of which may be beyond our control.

As a private company, we were not required to assess and conclude on the effectiveness of our internal control over financial reporting in a manner that meets the standards of publicly traded companies required by Section 404(a). Our management has not completed a comprehensive assessment of the effectiveness of our internal control over financial reporting, and our independent registered public accounting firm has not conducted an audit of our internal control over financial reporting. We will not be required, pursuant to Section 404, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting until the year following our first annual report required to be filed with the SEC. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. At that time, our management may conclude that our internal control over financial reporting remains not effective. In addition, once we cease to qualify as an “emerging growth company,” our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting. Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may disagree with our assessment and may issue a report that contains an adverse opinion if, in their evaluation, there are deficiencies that, individually or in combination, result in one or more material weaknesses.

The process of designing and implementing effective internal controls is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company. Moreover, our compliance with Section 404 will require that we incur substantial expenses and expend significant management efforts. Testing and maintaining internal controls may divert our management’s attention from other matters that are important to our business. During the course of implementing, documenting and testing our internal control over financial reporting, in order to satisfy the requirements of Section 404, we may

72

identify other weaknesses and deficiencies in our internal control over financial reporting and disclosure controls and procedures. Further, despite our efforts to implement and maintain effective internal control over financial reporting and disclosure controls and procedures, we may not be able to detect or prevent all errors or instances of fraud and additional weaknesses in our internal control over financial reporting may be identified in the future.

A material weakness in our internal control over financial reporting, failure to maintain effective disclosure controls and procedures or any difficulties encountered in their implementation or improvement could lead to errors in our annual or interim financial statements or restatements of previously issued financial statements or could cause us to fail to meet our financial reporting obligations, any of which could adversely affect our business, results of operations, financial condition and future prospects. Such failures could also lead to a loss of investor confidence in the accuracy and completeness of our financial reports, which in turn could have a negative impact on the market price of our Pubco Stock. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud, misuse of corporate assets and legal actions under U.S. securities laws and subject us to potential delisting from Nasdaq to regulatory investigations and to civil or criminal sanctions. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

Pubco’s failure to timely and effectively implement controls and procedures required by Section 404(a) of the Sarbanes-Oxley Act that will be applicable to it following consummation of the Business Combination could have a material adverse effect on its business, financial condition, results of operations, cash flow and prospects.

Section 404 of the Sarbanes-Oxley Act will require Pubco to evaluate the effectiveness of its internal control over financial reporting as of the end of each fiscal year, including a management report assessing the effectiveness of its internal control over financial reporting beginning with its first Annual Report on Form 10-K for the year in which the Business Combination is consummated. Additionally, once Pubco ceases to be an emerging growth company, its independent registered accounting firm will also be required to attest to the effectiveness of its internal control over financial reporting in each Annual Report on Form 10-K to be filed with the SEC. Pubco may in the future identify material weaknesses or significant deficiencies that it may be unable to remedy before the requisite deadline for those reports. Pubco’s ability to comply with the annual internal control reporting requirements will depend on the effectiveness of its financial reporting and data systems and controls across its company. Pubco expects these systems and controls to involve significant expenditures and to become increasingly complex as its business grows. To effectively manage this complexity, Pubco will need to continue to improve its operational, financial and management controls and its reporting systems and procedures. Any weaknesses or deficiencies or any failure to implement required new or improved controls, or difficulties encountered in the implementation or operation of these controls, could harm its operating results and cause it to fail to meet its financial reporting obligations or result in material misstatements in its financial statements, which could adversely affect our business and reduce the market price of Pubco Class A Stock.

Pubco will be an “emerging growth company” under the JOBS Act. The reduced public company reporting requirements applicable to emerging growth companies may make Pubco Class A Stock less attractive to investors.

Pubco will qualify as an “emerging growth company,” as defined in the JOBS Act. While Pubco remains an emerging growth company, it will be permitted to and plans to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These provisions include: (i) an exemption from compliance with the auditor attestation requirement in the assessment of Pubco’s internal control over financial reporting pursuant to Section 404 of Sarbanes-Oxley, (ii) not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, (iii) reduced disclosure obligations regarding executive compensation arrangements in Pubco’s periodic reports, registration statements and proxy statements, and (iv) exemptions from the requirements of holding a non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As a result, the information Pubco provides will be different than the information that is available with respect to other public companies that are not emerging growth companies.

In addition, Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act as long as Pubco is an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The JOBS Act provides that a company can elect to opt out of the extended

73

transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable.

Pubco cannot predict whether investors will find Pubco Class A Stock less attractive if it relies on these exemptions. If some investors find Pubco Class A Stock less attractive as a result, there may be a less active trading market for Pubco Class A Stock. The market price of Pubco Class A Stock may be more volatile.

Pubco expects to remain an emerging growth company until the earlier of (i) the last day of the fiscal year (1) following the fifth anniversary of the consummation of the Business Combination, (2) in which Pubco has total annual gross revenue of at least $1.235 billion, or (3) in which Pubco is deemed to be a large accelerated filer, which means the market value of Pubco Stock that is held by non-affiliates equaled or exceeded $700 million as of the end of that year’s second fiscal quarter, and (ii) the date on which Pubco has issued more than $1 billion in non-convertible debt securities during the prior three-year period.

If securities or industry analysts do not publish research or reports about Pubco’s business or publish negative reports, the market price of Pubco Class A Stock could decline.

The trading market for Pubco Class A Stock will be influenced by the research and reports that industry or securities analysts publish about Pubco or Pubco’s business. Pubco may be unable or slow to attract research coverage and if one or more analysts cease coverage of Pubco, the price and trading volume of Pubco’s securities would likely be negatively impacted. If any of the analysts that may cover Pubco change their recommendation regarding Pubco’s securities adversely, or provide more favorable relative recommendations about Pubco’s competitors, the price of Pubco’s securities would likely decline. If any analyst that may cover Pubco ceases covering Pubco or fails to regularly publish reports on Pubco, it could lose visibility in the financial markets, which could cause the price or trading volume of Pubco’s securities to decline. If one or more of the analysts who cover Pubco downgrades Pubco Class A Stock or if Pubco’s reporting results do not meet their expectations, the market price of Pubco Class A Stock could decline. Moreover, the market price of Pubco Class A Stock may decline after the Business Combination if Pubco does not achieve the perceived benefits of the Business Combination as rapidly or to the extent anticipated by financial analysts, or the effect of the Business Combination on Pubco’s financial results is not consistent with the expectations of financial analysts. Accordingly, holders of Pubco Stock following the consummation of the Business Combination may experience a loss as a result of a decline in the market price of Pubco Class A Stock. In addition, a decline in the market price of Pubco Class A Stock following the consummation of the Business Combination could adversely affect Pubco’s ability to issue additional securities and to obtain additional financing in the future.

Pubco may be subject to material litigation, including individual and class action lawsuits, as well as investigations and enforcement actions by regulators and governmental authorities. These matters are often expensive and time consuming, and, if resolved adversely, could harm Pubco’s business, financial condition and operating results.

We may from time to time become subject to claims, arbitrations, individual and class action lawsuits with respect to a variety of matters, including employment, consumer protection, advertising and securities. In addition, we may from time to time become subject to, government and regulatory investigations, inquiries, actions or requests, other proceedings and enforcement actions alleging violations of laws, rules and regulations, both foreign and domestic. The scope, determination and impact of claims, lawsuits, government and regulatory investigations, enforcement actions, disputes and proceedings to which we are subject cannot be predicted with certainty, and may result in:

• substantial payments to satisfy judgments, fines or penalties;

• substantial outside counsel, advisor and consultant fees and costs;

• substantial administrative costs, including arbitration fees;

• additional compliance and licensure requirements;

• loss or non-renewal of then-existing licenses or authorizations, or prohibition from or delays in obtaining additional licenses or authorizations, required for our business;

74

• loss of productivity and high demands on employee time;

• criminal sanctions or consent decrees;

• termination of certain employees, including members of our executive team;

• barring of certain employees from participating in our business in whole or in part;

• orders that restrict our business or prevent us from offering certain products or services;

• changes to our business model and practices;

• an inability to deliver on our strategy;

• delays to planned transactions, product launches or improvements; and

• damage to our brand and reputation.

Regardless of the outcome, any such matters can have an adverse impact, which may be material, on our business, operating results or financial condition because of legal costs, diversion of management resources, reputational damage and other factors.

Since members of the Advisory Board have interests that are different from, or in addition to (and which may conflict with) the interests of Pubco, a conflict of interest may arise in connection with their Advisory Board services.

In addition to their roles on the Advisory Board of Pubco, Emin Gun Sirer acts as Chief Executive Officer of Ava Labs, Haseeb Qureshi acts as a Managing Partner of Dragonfly, Jason Yanowitz acts as Chief Executive Officer of Blockworks Inc. and Stani Kulechov acts as Chief Executive Officer of Aave Labs. While the businesses affiliated with the Advisory Board members and Pubco currently share a strong alignment of interests, in particular the promotion and support of the digital asset market generally and the Avalanche ecosystem in particular, we cannot guarantee that these interests will remain fully aligned in the future. As each entity associated with our Advisory Board members pursues its own strategic objectives, business priorities or operational mandates, circumstances may arise in which their interests diverge. For example, decisions regarding the allocation of resources, the prioritization of development initiatives or the structuring of partnerships and incentives may benefit one entity to the detriment of the other. Additionally, the existence of diverging personal or financial interests may lead to actual or perceived conflicts of interest for Advisory Board members when making decisions that impact both organizations. Any such conflicts, if not properly managed, could adversely affect the governance, operations or reputation of Pubco and harm Pubco’s business.

Risks Related to the Business Combination

The market price of shares of Pubco Class A Stock after the Business Combination will be affected by factors different from those currently affecting the market price of MLAC Class A Ordinary Shares.

The market price of shares of Pubco Class A Stock after the Business Combination will be influenced by various factors, distinct from those affecting the market price of MLAC Class A Ordinary Shares before the Business Combination. These include the financial performance of Pubco, economic conditions, market trends, AVAX price performance, investor psychology, relative governance rights and political and social factors.

The market price of Pubco Class A Stock may change significantly following the Business Combination. The stock market recently has experienced extreme volatility. This volatility often has been unrelated or disproportionate to the operating performance of particular companies. Public Shareholders may not be able to resell their shares of Pubco Class A Stock at an attractive price due to a number of factors such as those listed in “Risks Related to the Business and Strategy of Pubco”, “Risks Related to Being a Public Company” and the following:

• results of operations that vary from the expectations of securities analysts and investors;

75

• results of operations that vary from those of Pubco’s competitors;

• changes in the market price of AVAX;

• changes in expectations as to Pubco’s future financial performance, including financial estimates and investment recommendations by securities analysts and investors;

• declines in the market prices of stocks generally;

• strategic actions by Pubco or its competitors;

• announcements by Pubco or its competitors of significant contracts, acquisitions, joint ventures, other strategic relationships or capital commitments;

• any significant change in Pubco’s management;

• changes in general economic or market conditions or trends in Pubco’s industry or markets;

• changes in business or regulatory conditions, including new laws or regulations or new interpretations of existing laws or regulations applicable to Pubco’s business;

• future sales by Pubco of Pubco Class A Stock or other securities;

• investor perceptions of the investment opportunity associated with Pubco Class A Stock relative to other investment alternatives;

• the public’s response to press releases or other public announcements by Pubco or third parties, including Pubco’s filings with the SEC;

• litigation involving Pubco, Pubco’s industry, or both, or investigations by regulators into the Pubco Board, Pubco’s operations or those of Pubco’s competitors;

• guidance, if any, that Pubco provides to the public, any changes in this guidance or Pubco’s failure to meet this guidance;

• the development and sustainability of an active trading market for Pubco Class A Stock;

• actions by institutional or activist shareholders;

• changes in accounting standards, policies, guidelines, interpretations or principles; and

• other events or factors, including those resulting from pandemics, natural disasters, war, acts of terrorism or responses to these events.

These broad market and industry fluctuations may adversely affect the market price of Pubco Class A Stock, regardless of Pubco’s actual operating performance. In addition, price volatility may be greater if the public float and trading volume of Pubco Class A Stock is low.

In the past, following periods of market volatility, shareholders have instituted securities class action litigation. If Pubco was involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from Pubco’s business regardless of the outcome of such litigation.

76

The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisfied or waived, the Business Combination Agreement may be terminated in accordance with its terms and the Business Combination may not be completed.

The Business Combination Agreement is subject to a number of conditions which must be fulfilled in order to complete the Business Combination. Those conditions include, among other things: approval of the MLAC Shareholder Approval Matters by MLAC Shareholders; absence of laws or orders prohibiting completion of the Business Combination; effectiveness of this proxy statement/prospectus; the shares of Pubco Class A Stock having been approved for listing on Nasdaq or any other national securities exchange; the accuracy of the representations and warranties by both parties (subject to the materiality standards set forth in the Business Combination Agreement); the performance in all material respects by the parties of their covenants and agreements related to the Business Combination; no occurrence of a material adverse effect on MLAC, Pubco or the Company and the completion of the Contribution. These conditions to the Closing of the Business Combination may not be fulfilled in a timely manner or at all, and, accordingly, the Business Combination may not be completed.

In addition, the parties can mutually decide to terminate the Business Combination Agreement at any time, before or after the approval of the MLAC Shareholder Approval Matters by the MLAC Shareholders, or Pubco, the Company or MLAC may elect to terminate the Business Combination Agreement in certain other circumstances. For more information, see the section entitled “Questions and Answers About the Proposals — Q. What conditions must be satisfied or waived to complete the Business Combination?” and the section entitled “The Business Combination Proposal — The Business Combination Agreement — Conditions to the Parties’ Obligations to the Closing.”

The Business Combination Agreement contains provisions that limit MLAC from seeking an alternative business combination. If the Business Combination is not completed, those restrictions may make it harder for MLAC to complete an alternate business combination before the end of the Combination Period.

While the Business Combination Agreement is in effect, MLAC may not solicit, assist, facilitate the making, submission or announcement of, or intentionally encourage any Acquisition Proposal, such as a merger, material sale of assets or equity interests or other business combination, with any third party, even though any such Alternative Transaction or Acquisition Proposal could be more favorable to MLAC Shareholders than the Business Combination. Further, if MLAC holds and concludes the Meeting but approval of the MLAC Shareholder Approval Matters is not obtained, either MLAC or Seller may terminate the Business Combination Agreement. If the Business Combination Agreement is terminated and the MLAC Board seeks another business combination, these provisions will make it more difficult for MLAC to complete an alternative business combination by the end of the Combination Period following the termination of the Business Combination Agreement due to the passage of time during which these provisions have remained in effect. There can be no assurance that MLAC will be able to find another acquisition target that would consummate a business combination or that such other business combination will be completed prior to the end of the Combination Period. For more information, see the section entitled “The Business Combination Proposal — Termination and Effects of Termination.”

The trading price of shares of Pubco Class A Stock after Closing is likely to be highly correlated to the price of AVAX which is volatile and can rise and fall rapidly and quickly and there is no guarantee that the price of AVAX after Closing will be greater than the Applicable Signing AVAX Price or the trading price of Pubco Class A Stock will be higher than the redemption price that Public Shareholders would have received if they redeemed their Public Shares.

As noted elsewhere in this proxy statement/prospectus, due to the initial assets of Pubco primarily comprising AVAX, the trading price of shares of Pubco Class A Stock following Closing is likely to be highly correlated to the price of AVAX. As a result, any increase or decrease in the price of AVAX could result in a corresponding increase or decrease in shares of Pubco Class A Stock. While AVAX has been a well performing asset since its mainnet launch in September 2020, the price of AVAX is volatile and can rise and fall rapidly and quickly and there is no guarantee that the price of AVAX will continue to rise or that the price of AVAX after Closing will be greater than the Applicable Signing AVAX Price or the trading price of Pubco Class A Stock will be higher than the redemption price that Public Shareholders would have received if they redeemed their Public Shares. For more information, see the risk factor entitled “— Pubco’s operating results, revenues and expenses may significantly fluctuate, including due to the highly volatile nature of AVAX, which could have an adverse effect on the market price of Pubco Class A Stock.”

(1) Assumes Pubco owns 15,007,339 AVAX, consisting of (i) 1,960,040 AVAX to be contributed by Seller pursuant to the Contribution Agreement, (ii) 3,533,745 AVAX to be contributed by the Company Unit Investors pursuant to the Company Unit Subscription Agreements, (iii) 2,195,588 AVAX purchased by Pubco with the net proceeds of the Company Unit Subscription at an average price of $27.09 and (iv) 7,317,966 AVAX purchased from the Foundation.

(2) Assumes AVAX to be purchased at illustrative future prices using (i) $239,698,022 of Cash-in-Trust, assuming no redemption of Public Shares, (ii) $898,346 of excess cash less (iii) $16,282,839 of estimated fees payable at closing.

(3) Illustrative Share Price of Pubco Class A Stock is calculated as (i) the product of (1) Illustrative Price of AVAX, (2) the number of AVAX and (3) the Illustrative mNAV divided by (ii) the pro forma number of shares of Pubco Class A Stock outstanding assuming no redemptions of Public Shares, including AVAT Management RSUs, Advisory Board Equity, and Sponsor Promote at closing; and including any shares related to the vesting of performance-based securities when appropriate (being 59,236,200 without incremental dilution from performance based securities up to 63,866,200 with full dilutive impact of performance based securities).

(4) Assumes a total of 4,630,000 performance-based units, with (i) 1,200,000 units at $13.00 per share, (ii) 1,543,333 units at $15.00 per share, (iii) 1,200,000 units at $17.00 per share, (iv) 343,333 units at $17.50 per share and (v) 343,333 units at $20.00 per share.

Public Shareholders should carefully review this table, as well as the current price of AVAX, as part of their analysis in determining the potential value of their Public Shares and determining whether or not to redeem their Public Shares in connection with the Business Combination.

For additional information, see the risk factors entitled “Pubco’s operating results, revenues and expenses may significantly fluctuate, including due to the highly volatile nature of AVAX, which could have an adverse effect on the market price of Pubco Class A Stock”.

The value of the MLAC Class B Ordinary Shares following completion of the Business Combination is likely to be substantially higher than the nominal price paid for them, even if the trading price of shares of Pubco Class A Stock at such time is substantially less than $10.00 per share, which may create an economic incentive for the MLAC management team to pursue and consummate the Business Combination which differs from the Public Shareholders.

The Sponsor and its Affiliates currently own 7,682,500 MLAC Ordinary Shares, including 7,187,500 MLAC Class B Ordinary Shares and 495,000 MLAC Private Placement Shares underlying 495,000 MLAC Private Units, which it purchased for $4,975,000 in the aggregate, comprised of the $25,000 purchase price for the MLAC Founder Shares (or approximately $0.003 per share) and the $4,950,000 purchase price for the MLAC Private Units (or $10.00 per share). Pursuant to the Sponsor Support Agreement, the Sponsor and its Affiliates have agreed to surrender, and which MLAC will cancel, 4,387,500 MLAC Class B Ordinary Shares immediately prior to, and subject to the consummation of, the MLAC Merger, resulting in the Sponsor retaining 2,800,000 MLAC Founder Shares immediately after such surrender (the “Retained Sponsor Shares”). The 495,000 MLAC Private Placement Shares

78

held by the Sponsor and its Affiliates (or any permitted distributees thereof, as applicable) will be forfeited immediately prior to the Closing pursuant to the Sponsor Support Agreement.

Assuming a trading price of $10.00 per share upon consummation of the Business Combination, the 2,800,000 MLAC Founder Shares (after accounting for the surrender of 4,387,500 MLAC Class B Ordinary Shares by the Sponsor immediately prior to the MLAC Merger and assuming full earnout of the 1,600,000 of shares of Pubco Class A Stock to be issued to the Sponsor and its Affiliates and held in escrow during the Earnout Period as disclosed elsewhere) would have an aggregate implied value of $28,000,000. Even if the trading price of shares of Pubco Class A Stock after Closing were to be as low as approximately $1.78 per share, the value of the MLAC Class B Ordinary Shares and MLAC Private Placement Shares would be equal to the Sponsor’s initial investment in MLAC of $4,975,000. As a result, the Sponsor and its Affiliates are likely to be able to recoup its investment in MLAC and make a substantial profit on that investment even if the Public Shares lose significant value. Accordingly, the Sponsor, and MLAC’s directors and officers who have an economic interest in the Sponsor, may have an economic incentive that differs from that of the Public Shareholders to pursue and consummate an initial business combination, including the Business Combination, rather than to liquidate and to return all of the cash in the Trust Account to the Public Shareholders, even if that business combination were with a riskier or less-established target business. This may have influenced the MLAC management team’s motivation in identifying and selecting AVAT as MLAC’s acquisition target and seeking to consummate the Business Combination. For the foregoing reasons, Public Shareholders should consider the MLAC management team’s financial incentive to complete the Business Combination when evaluating whether to redeem their Public Shares in connection with the consummation of the Business Combination. See also “Since the Sponsor and its Affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders, a conflict of interest may have existed in determining whether the Business Combination with Pubco and the Company is appropriate as MLAC’s initial business combination. Such interests include that the Sponsor and its Affiliates will lose their entire investment in MLAC if the Business Combination is not completed or any other business combination is not completed.”

The “net cash” per Public Share not being redeemed will be less than the redemption price.

Each Public Share not being redeemed will represent a “net cash” per share contribution equal to its pro rata share of the Trust Account by that Public Shareholder to Pubco (which, as of May 4, 2026, was approximately $10.62 which is the approximate redemption amount per Public Share based on the Trust Account balance as of May 4, 2026 (including interest earned on the funds held in the Trust Account but less taxes payable). This represents a higher contribution of net cash per share to Pubco than (i) the Additional Merger Consideration Shares, which are being issued at $10.00 per share, (ii) the $25,000 that was contributed by the Sponsor to MLAC in exchange for 7,187,500 MLAC Class B Ordinary Shares (equal to approximately $0.003 per share), and (iii) the shares that may be issued to the Sponsor and its Affiliates from conversion of the MLAC Working Capital Loans, at a price of $10.00 per unit). Accordingly, assuming that the “net cash” per Public Share being contributed to Pubco reflects the cash being contributed at Closing by MLAC to Pubco (i.e., the Trust Account balance net of redemptions and any cash balances of MLAC outside of the Trust Account), the redemption price is expected to be greater than the net cash per share contributed by MLAC to Pubco.

Public Shareholders who do not redeem their Public Shares will experience substantial and immediate dilution upon Closing of the Business Combination as a result of the MLAC Class B Ordinary Shares held by the Sponsor, since the value of the MLAC Class B Ordinary Shares is likely to be substantially higher than the nominal price paid for them, as well as a result of the issuance of the shares of Pubco Stock in the Business Combination and as a result of the conversion of the Company Units.

The issuance of a significant number of shares of Pubco Stock in connection with the Transactions will dilute the equity interests of Public Shareholders in Pubco following the Business Combination and may adversely affect prevailing market prices for shares of Pubco Class A Stock.

In addition, the Sponsor acquired the MLAC Class B Ordinary Shares at a nominal price, also significantly contributing to this dilution. It is anticipated that, upon the completion of the Transactions and assuming the Applicable Signing AVAX Price:

a) assuming, among other things, that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination, that no shares of Pubco Class A Stock are issued pursuant to the Incentive Plan and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements, (i) Public Shareholders (including the MLAC Right Holders) will own approximately 41.8% of the issued and outstanding shares of Pubco Class A Stock, (ii) the Company Unit Investors will own approximately 35.7% of the issued and outstanding shares of Pubco Class A Stock, (iii) the Sponsor and its Affiliates will own approximately 4.6% of the issued and outstanding shares of

Pubco Class A Stock, (iv) Seller Related Parties will own approximately 9.6% of the issued and outstanding shares of Pubco Class A Stock, (v) Astral will own approximately 3.3% of the issued and outstanding shares of Pubco Class A Stock, and (vi) the Foundation will own approximately 5.0% of the issued and outstanding shares of Pubco Class A Stock;

b) assuming, among other things, that 25% of the Public Shares are redeemed upon completion of the Business Combination, that no shares of Pubco Class A Stock are issued pursuant to the Incentive Plan and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements, (i) Public Shareholders (including MLAC Right Holders) will own approximately 35.7% of the issued and outstanding shares of Pubco Class A Stock, (ii) the Company Unit Investors will own approximately 39.4% of the issued and outstanding shares of Pubco Class A Stock, (iii) the Sponsor and its Affiliates will own approximately 5.1% of the issued and outstanding shares of Pubco Class A Stock, (iv) Seller Related Parties will own approximately 10.6% of the issued and outstanding shares of Pubco Class A Stock, (v) Astral will own approximately 3.7% of the issued and outstanding shares of Pubco Class A Stock, and (vi) the Foundation will own approximately 5.5% of the issued and outstanding shares of Pubco Class A Stock;

c) assuming, among other things, that 50% of the Public Shares are redeemed upon completion of the Business Combination, that no shares of Pubco Class A Stock are issued pursuant to the Pubco Incentive Plan and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements, (i) Public Shareholders (including MLAC Right Holders) will own approximately 28.3% of the issued and outstanding shares of Pubco Class A Stock, (ii) the Company Unit Investors will own approximately 44.0% of the issued and outstanding shares of Pubco Class A Stock, (iii) the Sponsor and its Affiliates will own approximately 5.7% of the issued and outstanding shares of Pubco Class A Stock, (iv) Seller Related Parties will own approximately 11.6% of the issued and outstanding shares of Pubco Class A Stock, (v) Astral will own approximately 4.1% of the issued and outstanding shares of Pubco Class A Stock, and (vi) the Foundation will own approximately 6.1% of the issued and outstanding shares of Pubco Class A Stock;

d) assuming, among other things, that 75% of the Public Shares are redeemed upon completion of the Business Combination, that no shares of Pubco Class A Stock are issued pursuant to the Incentive Plan and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements, (i) Public Shareholders (including MLAC Right Holders) will own approximately 18.8% of the issued and outstanding shares of Pubco Class A Stock, (ii) the Company Unit Investors will own approximately 49.8% of the issued and outstanding shares of Pubco Class A Stock, (iii) the Sponsor and its Affiliates will own approximately 6.5% of the issued and outstanding shares of Pubco Class A Stock, (iv) Seller Related Parties will own approximately 13.4% of the issued and outstanding shares of Pubco Class A Stock, (v) Astral will own approximately 4.6% of the issued and outstanding shares of Pubco Class A Stock, and (vi) the Foundation will own approximately 6.9% of the issued and outstanding shares of Pubco Class A Stock; and

e) assuming, among other things, that 100% of the Public Shares are redeemed upon completion of the Business Combination, that no shares of Pubco Class A Stock are issued pursuant to the Incentive Plan and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements, (i) Public Shareholders (including MLAC Right Holders) will own approximately 6.4% of the issued and outstanding shares of Pubco Class A Stock, (ii) the Company Unit Investors will own approximately 57.3% of the issued and outstanding shares of Pubco Class A Stock, (iii) the Sponsor and its Affiliates will own approximately 7.5% of the issued and outstanding shares of Pubco Class A Stock, (iv) Seller Related Parties will own approximately 15.5% of the issued and outstanding shares of Pubco Class A Stock, (v) Astral will own approximately 5.3% of the issued and outstanding shares of Pubco Class A Stock, and (vi) the Foundation will own approximately 8.0% of the issued and outstanding shares of Pubco Class A Stock.

These ownership percentages assume a $10.00 share price and other assumptions set forth in the section entitled “Summary of the Proxy Statement/Prospectus — Ownership of Pubco After the Transactions,” “Questions and Answers About the Proposals — What equity stake will current Public Shareholders (including MLAC Right Holders), the Company Unit Investors, the Sponsor and its Affiliates, the Foundation, Astral and Seller Related Parties hold in Pubco immediately after the completion of the Transactions?” in this proxy statement/prospectus. As such, Public Shareholders who do not redeem their Public Shares will experience substantial and immediate dilution upon Closing. For more information, see the section entitled “Summary of the Proxy Statement/Prospectus — Dilution.”

Additionally, future issuances of Pubco Class A Stock, including pursuant to the Incentive Plan or as Adjustment Units pursuant to the Company Unit Subscription Agreements, may significantly dilute the equity interests of Public Shareholders who do not redeem their Public Shares and may adversely affect prevailing market prices for Pubco Class A Stock.

80

Further, Pubco may also, from time to time in the future, issue additional shares of Pubco Class A Stock or securities convertible into Pubco Class A Stock pursuant to a variety of transactions, including acquisitions or other capital markets transactions. Issuing additional shares of its capital stock, other equity securities, or securities convertible into equity may dilute the economic and voting rights of Public Shareholders, reduce the market price of Pubco Class A Stock, or both. Preference shares (if issued) could have a preference with respect to liquidating distributions or a preference with respect to dividend payments that could limit Pubco’s ability to pay dividends to the holders of Pubco Class A Stock. Pubco’s decision to issue securities in any future offering will depend on market conditions and other factors beyond its control, which may adversely affect the amount, timing or nature of its future offerings. As a result, holders of Pubco Class A Stock upon the Closing, including Public Shareholders who do not redeem their Public Shares, will bear the risk that future offerings may reduce the market price of Pubco Class A Stock and dilute their percentage ownership further.

If Public Shareholders who wish to exercise their redemption rights in connection with the Business Combination fail to properly demand such redemption rights, they will not be entitled to convert their Public Shares into a pro rata portion of the Trust Account and will instead become stockholders of Pubco.

In connection with the Business Combination, Public Shareholders may demand that MLAC redeem their Public Shares at the Closing in return for a pro rata portion of the funds available in the Trust Account, calculated as of two business days prior to the Closing Date. Public Shareholders who seek to exercise this redemption right must deliver their Public Shares (either physically or electronically) to CST at least two (2) business days prior to the Meeting. Any Public Shareholder who fails to properly demand redemption rights will not be entitled to redeem their Public Shares and receive a pro rata portion of the funds available in the Trust Account and will instead exchange their Public Shares for shares of Pubco Class A Stock and become stockholders of Pubco. See the section of this proxy statement/prospectus entitled “Extraordinary General Meeting of MLAC Shareholders — Redemption Rights” for the procedures to be followed.

Public Shareholders will not have any rights or interests in funds from the Trust Account except under certain limited circumstances, which includes in connection with the consummation of the Business Combination. Therefore, for a Public Shareholder to liquidate their investment in MLAC prior to such times, a Public Shareholder may be forced to sell their Public Shares in the open market, potentially at a loss.

Public Shareholders will be entitled to receive funds from the Trust Account only upon the earlier to occur of: (i) MLAC’s completion of the Business Combination or another business combination if the Business Combination is not consummated, and then only in connection with those Public Shares that Public Shareholders have properly elected to redeem, subject to the limitations described herein, (ii) the redemption of Public Shares if MLAC is unable to complete a business combination by the end of the Combination Period, subject to applicable law and as further described herein, or (iii) in connection with an extension of the Combination Period or certain amendments made to the MLAC Memorandum and Articles, as further described herein. In no other circumstances will a Public Shareholder have any right or interest of any kind in the Trust Account. Accordingly, for a Public Shareholder to liquidate their investment in MLAC prior to such times, a Public Shareholder may be forced to sell their Public Shares in the open market, potentially at a loss.

The ability of Public Shareholders to exercise redemption rights with respect to a large number of MLAC Class A Ordinary Shares may reduce proceeds available to Pubco after Closing, reduce the public “float” of shares of Pubco Class A Stock after Closing, reduce the liquidity of the trading market for the shares of Pubco Class A Stock after Closing, or make it difficult to obtain or maintain the quotation, listing or trading shares of Pubco Class A Stock on Nasdaq or another national securities exchange, and consequently may not allow the parties to complete the Business Combination, or optimize Pubco’s capital structure following the Business Combination.

Public Shareholders may vote in favor of the Business Combination and still elect to redeem their shares. We do not know how many Public Shareholders may exercise their redemption rights in connection with the Business Combination. If a larger number of Public Shares are submitted for redemption than we initially expected, we may need to arrange for additional debt or equity financing to provide working capital to Pubco following the Closing. There can be no assurance that such debt or equity financing will be available to us if we need it or, if available, the terms will be satisfactory to us. Raising additional third-party financing may involve dilutive equity issuances or the incurrence of indebtedness at higher than desirable levels and may increase the probability that the Business Combination will be unsuccessful.

81

In such event, if adequate third-party financing is unavailable or only available on unreasonable terms, Pubco may not be able to maintain the listing of its securities on Nasdaq or another national securities exchange for lack of liquidity and may not have sufficient cash and liquidity to finance its operations as currently contemplated following the Business Combination.

The MLAC Articles do not provide a specified maximum redemption threshold, however $1.0 million representing the underwriting fee must be paid from the funds on deposit in the Trust Account pursuant to the Amended Underwriting Agreement. The absence of a redemption threshold, other than the threshold set by the $1.0 million payable pursuant to the Amended Underwriting Agreement, may increase the risk of being subject to the “penny stock” rules or the risk that MLAC or Pubco’s securities may be delisted from Nasdaq.

The MLAC Articles do not provide a specified maximum redemption threshold, however $1.0 million representing the underwriting fee must be paid from the funds on deposit in the Trust Account pursuant to the Amended Underwriting Agreement. As a result, MLAC may be able to complete the Business Combination even though a substantial majority of MLAC Public Shareholders do not agree with the Business Combination and have redeemed their shares. Furthermore, Public Shares may be able to be redeemed in an amount that could cause MLAC or Pubco’s net tangible assets to be less than $5,000,001 upon consummation of its initial business combination or the Business Combination respectively (such that MLAC or Pubco may become subject to the SEC’s “penny stock” rules). The “penny stock” rules impose additional sales practice requirements on broker-dealers who sell securities to persons other than established customers and accredited investors. For transactions covered by these rules, the broker-dealer must make a special suitability determination for the purchase of securities and have received the purchaser’s written consent to the transaction before the purchase. Additionally, for any transaction involving a penny stock, unless exempt, the broker-dealer must deliver, before the transaction, a disclosure schedule prescribed by the SEC relating to the penny stock market. The broker-dealer also must disclose the commissions payable to both the broker-dealer and the registered representative and current quotations for the securities. Finally, monthly statements must be sent disclosing recent price information on the limited market in penny stocks, Although we expect to meet Nasdaq’s initial listing requirements upon closing of the Business Combination and to not be subject to “penny stock” rules, these additional burdens imposed on broker-dealers restrict the ability and decrease the willingness of broker-dealers to sell Public Shares, in the event the Business Combination is not consummated, or Pubco Stock, in the event the Business Combination is consummated, which we believe may result in decreased liquidity for such securities as well as increased transaction costs for sales and purchases of such securities as compared to other securities.

Moreover, if MLAC redeems its Public Shares in an amount that would cause its or Pubco’s net tangible assets to be less than $5,000,001 and MLAC’s or Pubco’s securities do not meet Nasdaq’s continued listing requirements, Nasdaq may delist MLAC or Pubco’s securities, as applicable, from trading on its exchange, If Nasdaq delists any of MLAC or Pubco’s securities from trading on its exchange and MLAC or Pubco are not able to list such securities on another approved national securities exchange, such securities could be quoted on an over-the-counter market, If this were to occur, MLAC or Pubco could face significant material adverse consequences, including (i) being subject to the “penny stock” rules as described above, (ii) a limited availability of market quotations for MLAC or Pubco’s securities, (iii) reduced liquidity for MLAC or Pubco’s securities, (iv) a decreased ability to issue additional securities or obtain additional financing in the future and (v) a less attractive acquisition vehicle to a target business in connection with an initial business combination (as applicable to MLAC).

Since the Sponsor and its Affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders, a conflict of interest may have existed in determining whether the Business Combination with Pubco and the Company is appropriate as MLAC’s initial business combination. Such interests include that the Sponsor and its Affiliates will lose their entire investment in MLAC if the Business Combination is not completed or any other business combination is not completed.

When Public Shareholders consider the recommendation of the MLAC Board to vote in favor of each of the Proposals, including the Business Combination Proposal, they should consider that the Sponsor and its Affiliates have interests in the Proposals that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders. The MLAC Board was aware of and considered these interests, among other matters, in evaluating and negotiating the Business Combination and transaction agreements and in recommending to MLAC Shareholders that they vote in favor of the Proposals presented at the Meeting, including

82

the Business Combination Proposal. MLAC Shareholders should take these interests into account in deciding whether to approve the Proposals. These interests include, among other things, the following:

• the Sponsor paid $25,000 for the 7,187,500 MLAC Class B Ordinary Shares. Of these amounts, contemporaneously with the consummation of the Business Combination, the Sponsor shall submit for cancellation 4,387,500 MLAC Class B Ordinary Shares, as a result, the Sponsor will retain the Retained Sponsor Shares. If the Business Combination or another MLAC initial business combination is not consummated by June 16, 2026 (or such other date as approved by the MLAC Shareholders), MLAC will cease all operations except for the purpose of winding up. In such event, the 2,800,000 Retained Sponsor Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be worthless because the holders thereof entered into an agreement waiving entitlement to participate in any redemption or liquidating distributions with respect to such shares. Neither the Sponsor nor any other person received any compensation in exchange for this agreement to waive redemption and liquidation rights. Pursuant to terms of the Insider Letter and the Sponsor Lock-Up Agreement, the Retained Sponsor Shares are subject to a lock-up whereby, subject to certain limited exceptions, the Retained Sponsor Shares are not transferable until the earlier of (A) the Anniversary Release; provided that, if the VWAP of the shares of Pubco Class A Stock equals or exceeds $12.50 per share for any 20 consecutive trading days after Closing, then the Anniversary Release will be deemed to occur at 11:59 p.m. (New York City time) on such 20th consecutive trading day, or (B) subsequent to MLAC’s initial business combination, the date on which Pubco consummates a transaction which results in all of its shareholders having the right to exchange their shares for cash, securities or other properties. (The Sponsor may, on or before the Closing of the Business Combination, distribute some or all of the Retained Sponsor Shares held by it and such distributed Retained Sponsor Shares may be released from lock-up restrictions in connection with applicable stock exchange listing requirements.) In this regard, while the Retained Sponsor Shares are not the same as the MLAC Class A Ordinary Shares, are subject to certain restrictions that are not applicable to the MLAC Class A Ordinary Shares, and may become worthless if MLAC does not complete a business combination by June 16, 2026 (or such other date as approved by the MLAC shareholders), the aggregate value of the 2,800,000 Retained Sponsor Shares owned by the Sponsor is estimated to be approximately $29.62 million, assuming the per share value of the Retained Sponsor Shares is the same as the $10.58 closing price of the MLAC Class A Ordinary Shares on Nasdaq on May 5, 2026;

• the Sponsor has agreed that the 1,600,000 shares of Pubco Class A Stock to be issued to the Sponsor (of the total 2,800,000 Retained Sponsor Shares it will hold), will be held in escrow during the Earnout Period, subject to early release upon certain price-based Triggering Events. Additionally, any Retained Sponsor Shares that are released from escrow shall not be sold or transferred until the Anniversary Release;

• the 495,000 MLAC Private Placement Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be forfeited immediately prior to the closing pursuant to the Sponsor Support Agreement. The Sponsor purchased the MLAC Private Placement Shares at an aggregate purchase price of $4,950,000, or $10.00 per unit, in the Private Placement consummated simultaneously with the MLAC IPO. The aggregate value of the 495,000 MLAC Private Placement Shares held by the Sponsor is estimated to be approximately $5.24 million, assuming the per unit value of the MLAC Private Placement Shares is the same as the $10.58 closing price of the MLAC Class Ordinary Shares on Nasdaq on May 5, 2026;

• if the proposed Business Combination is consummated, immediately after the Closing the Sponsor and its Affiliates are anticipated to hold 4.5% of the outstanding shares of Pubco Common Stock, based on the assumptions set forth in the section of this proxy statement/prospectus entitled “Share Calculations and Ownership Percentages”, which also incorporate relevant assumptions further described in the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information” and “Beneficial Ownership of Securities” and assuming, among other assumptions further described in aforementioned sections of this proxy statement/ prospectus, no redemptions of Public Shares and no conversion of public share rights or private share rights prior to or in connection with the proposed Business Combination;

• based on the difference in the effective purchase price of $0.003 per share paid for the MLAC Class B Ordinary Shares, as compared to the purchase price of $10.00 per Unit sold in the MLAC IPO, the Sponsor and its members may earn a positive rate of return even if the share price of Pubco after the Closing falls below the price initially paid for the MLAC Units in the MLAC IPO and the unredeeming unaffiliated Public Shareholders experience a negative rate of return following the Closing of the Business Combination;

83

• if, prior to the Closing, the Sponsor provides working capital loans to MLAC, up to $1,500,000 of which may be convertible into MLAC Private Placement Shares at the option of the Sponsor, such loans may not be repaid if no business combination is consummated and MLAC is forced to liquidate; provided, however, that, as of the date of this proxy statement/prospectus, there are no such working capital loans outstanding;

• unless MLAC consummates an initial business combination, it is possible that MLAC’s officers, directors and the Sponsor may not receive reimbursement for out-of-pocket expenses incurred by them, to the extent that such expenses exceed the amount of available funds not deposited in the Trust Account (provided, however, that, as of the date of this proxy statement/prospectus, MLAC’s officers and directors have not incurred (nor are any of them expecting to incur) out-of-pocket expenses exceeding such funds available to MLAC for reimbursement thereof, but provided, further, that if any such expenses are incurred prior to consummation of the Business Combination, MLAC’s officers, directors and the Sponsor may not receive reimbursement therefor if the proposed Business Combination is not consummated);

• if the Trust Account is liquidated, including in the event MLAC is unable to complete an initial business combination by June 16, 2026 (or such other date as approved by the MLAC shareholders),the Sponsor has agreed that it will be liable to MLAC, if and to the extent any claims by a third party for services rendered or products sold to MLAC (except for MLAC’s independent auditors) or a prospective target business with which MLAC has entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per share due to reductions in the value of the trust assets less taxes payable, provided, however, that such liability will not apply to any claims by a third party or prospective target business that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable), nor will it apply to any claims under MLAC’s indemnity of the underwriters of the MLAC IPO against certain liabilities, including liabilities under the Securities Act;

• the Sponsor and its Affiliates may benefit from the completion of a business combination and may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to shareholders rather than liquidate;

• MLAC agreed to pay Paul Grinberg (“Mr. Grinberg”), MLAC’s Chairman and Chief Executive Officer and Douglas Horlick, MLAC’s President and Chief Financial Officer, an aggregate of up to $20,000 per month for their services as executive officers and directors of MLAC, until the earlier to occur of the completion of MLAC’s initial business combination or its liquidation. As of December 31, 2025, MLAC has incurred and paid an expense of $240,000 of such fee; and

• MLAC’s officers and directors will be eligible for continued indemnification and continued coverage under a tail policy for MLAC’s directors’ and officers’ liability insurance policy for up to a six-year period from and after the Closing for events occurring prior to the Closing, which tail policy is to be paid for by Pubco at the Closing pursuant to the Business Combination Agreement. If the Business Combination does not close, MLAC’s officers and directors may not receive this tail insurance coverage.

• the anticipated election of Mr. Grinberg, MLAC’s Chairman and Chief Executive Officer, as director of Pubco after the consummation of the Business Combination. As such, in the future, such directors will receive any cash fees, stock options or stock awards that the Pubco Board determines to pay to such directors.

• in addition to the interests of the Sponsor and its Affiliates in the Business Combination, MLAC shareholders should be aware that MLAC’s underwriter for its IPO, BTIG, may also have financial interests that are different from, or in addition to, the interests of MLAC shareholders, including the fact that:

• pursuant to an amendment to the underwriting agreement in connection with MLAC’s IPO, BTIG may receive a deferred fee equal to $1,000,000, and such fees are payable at the closing of the Business Combination only if MLAC completes the Business Combination; and pursuant to the Sponsor Support Agreement, BTIG will forfeit its 310,000 MLAC Private Placement Shares; and

• pursuant to the BTIG Financial Advisory Services Agreement, BTIG may receive reimbursement of all reasonable out-of-pocket expense as financial advisor to MLAC in connection with the Business Combination, (provided that, if the

84

expense exceeding $100,000, BTIG shall submit to MLAC for its prior written approval), such reimbursement are payable at the closing of the Business Combination only if MLAC completes an initial business combination.

Additionally, in considering the recommendation of the MLAC Board to vote in favor of approval of the Proposals, unaffiliated MLAC Shareholders should keep in mind that the directors and executive officers of Pubco and Company have interests in such Proposals that are different from or in addition to, those of unaffiliated MLAC Shareholders. In particular:

• the Company has entered into offer letters with its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer that are expected to be assigned to Pubco at the Closing;

• Pubco intends to grant equity awards under the Incentive Plan to its Chief Executive Officer, Chief Financial Officer and Chief Operating Officer;

• the fact that Gerald Bartholomew Smith, the Company’s Chief Executive Officer, is expected to become a director and Chief Executive Officer of Pubco at Closing; and

• the Company’s Chief Executive Officer is party to an advisory agreement with Avalanche BVI that provides for payment of certain consideration if the Closing does not occur; however, in the event that the Closing does occur, Gerald Bartholomew Smith will no longer serve as an advisor to Avalanche BVI nor receive any compensation from Avalanche BVI.

For additional information, see the section of this proxy statement/prospectus entitled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and its Affiliates in the Business Combination” and “Executive and Director Compensation.”

The existence of personal and financial interests of one or more of MLAC’s directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of MLAC and the Public Shareholders and what he or she may believe is best for himself, herself or themselves in determining to recommend that Public Shareholders vote for the Proposals. The personal and financial interests of the Sponsor and its Affiliates may have influenced their motivation in identifying and selecting the Company as an acquisition target and completing the Business Combination. The absence of a fairness opinion (or any similar report or appraisal) exacerbates the possibility that these risks impacted the terms of the Business Combination Agreement.

The MLAC Board reviewed and considered the potential conflicting interests described above with respect to the Sponsor and its Affiliates, and, after taking into account the factors they deemed applicable (including the potential conflicting interests), unanimously approved the Business Combination Agreement and the transactions contemplated therein.

Nonetheless, in considering the recommendations of the MLAC Board to vote for each of the Proposals, Public Shareholders should consider these interests. For additional information on the interests and relationships of the Sponsor and its Affiliates in the Business Combination, see “The Business Combination Proposal — Interests of the Sponsor and its Affiliates in the Business Combination.” See also “The value of the MLAC Class B Ordinary Shares following completion of the Business Combination is likely to be substantially higher than the nominal price paid for them, even if the trading price of shares of Pubco Class A Stock at such time is substantially less than $10.00 per share, which may create an economic incentive for the MLAC management team to pursue and consummate the Business Combination which differs from the Public Shareholders.”

Neither the MLAC Board nor any committee thereof obtained a fairness opinion (or any similar report or appraisal) in determining whether or not to pursue the Business Combination. Consequently, MLAC Shareholders have no assurance from an independent source that the number of shares of Pubco Stock to be issued to Seller and MLAC Shareholders in the Business Combination is fair to MLAC — and, by extension, MLAC Shareholders — from a financial point of view.

In considering the Business Combination, neither the MLAC Board nor any committee thereof obtained a fairness opinion from an independent investment banking firm or another independent firm that commonly renders opinions that the terms of the Business Combination are fair to MLAC Shareholders from a financial point of view. In analyzing the Business Combination, the MLAC Board reviewed the information provided to it by its management, representatives of the Sponsor and MLAC’s legal and financial advisors. In addition, before determining that the Business Combination was in the best interests of MLAC and its shareholders, the MLAC

85

Board reviewed various industry data, including a review of recent performance of public companies with the digital asset treasury strategies, such as MicroStrategy, as well as industry insights provided by the Investment Banks, which were included in the investor presentation for the Company Unit Subscription. The MLAC Board also consulted with its financial and legal advisors and with MLAC management and considered a number of factors, uncertainty and risks, including, but not limited to, those discussed under “The Business Combination Proposal — MLAC Board’s Reasons for Approval of the Business Combination,” and concluded that the Business Combination was in the best interests of MLAC and the MLAC Shareholders. The MLAC Board believes that because of the professional experience and background of its directors, it was qualified to conclude that the Business Combination was fair from a financial perspective to MLAC Shareholders and that the fair market value of the business or assets to be acquired in the Business Combination was at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest income earned on the Trust Account) at the time of the execution of the Business Combination Agreement). Accordingly, investors will be relying solely on the judgment of the MLAC Board in valuing AVAT, and the MLAC Board may not have properly valued such businesses. As a result, the terms may not be fair from a financial point of view to MLAC Shareholders. The lack of a fairness opinion (or any similar report or appraisal) may also lead to an increased number of Public Shareholders to vote against the Business Combination or demand redemption of their Public Shares, which could potentially impact MLAC’s ability to consummate the Business Combination. For information about the standards used by the MLAC Board in evaluating the Business Combination, see the section of this proxy statement/prospectus entitled “The Business Combination Proposal — Background of the Business Combination.”

The parties to the Business Combination Agreement may waive one or more of the conditions to the Business Combination or certain of the other transactions contemplated by the Business Combination Agreement.

The parties to the Business Combination Agreement may agree to waive, in whole or in part, some of the conditions to the obligations to consummate the Business Combination or certain of the other transactions contemplated by the Business Combination Agreement, to the extent permitted by the MLAC Memorandum and Articles, the Company Unit Subscription Agreements, the Cayman Act and applicable laws. For example, it is a condition to MLAC’s obligations to consummate the Business Combination that certain of Pubco’s, the Company’s and Seller’s representations and warranties are true and correct in all respects as of the Closing, subject to the materiality exceptions set forth in the Business Combination Agreement. However, if the MLAC Board determines that it is in the best interest of MLAC to waive any such breach, then the MLAC Board may elect to waive that condition and consummate the Business Combination; provided that no party is able to waive the condition that MLAC Shareholders approve the Business Combination Proposal.

MLAC’s directors and officers will have discretion on whether to agree to changes or waivers in the terms of the Business Combination Agreement, and their interests in exercising that discretion may conflict with those of the MLAC Shareholders.

In the period leading up to the Closing, events may occur that, pursuant to the Business Combination Agreement, would require MLAC to agree to amend the Business Combination Agreement, to consent to certain actions taken by Pubco or the Company or to waive or exercise rights that MLAC is entitled to under the Business Combination Agreement. Such events could arise because of a request by Pubco or the Company to undertake actions that would otherwise be prohibited by the terms of the Business Combination Agreement or the occurrence of other events that would have a material adverse effect on Pubco’s expected business strategy and would entitle MLAC to terminate the Business Combination Agreement. In any of such circumstances, it would be at MLAC’s discretion, acting through the MLAC Board, to grant its consent or waive those rights.

The existence of the financial and personal interests of one or more of the directors of MLAC described in the preceding risk factors (and as described elsewhere in this proxy statement/prospectus) may result in a conflict of interest on the part of one or more of the directors between such director’s potential beliefs in what is best for MLAC and such director’s potential beliefs in what is best for himself or herself in determining whether or not to take the requested action.

In the event that MLAC, Pubco, the Company and the other parties to the Business Combination Agreement authorize an amendment to the Business Combination Agreement that does not require further approval by MLAC Shareholders, MLAC will inform MLAC Shareholders of such amendment by press release and other public communication. In the event that MLAC, Pubco, the Company and the other parties to the Business Combination Agreement authorize an amendment to the Business Combination Agreement that requires further approval by MLAC Shareholders, to the extent this proxy statement/prospectus has been mailed to MLAC Shareholders, a proxy supplement or an amended proxy statement/prospectus would be delivered to MLAC Shareholders, and proxies would be re-solicited for approval of such amendment.

86

MLAC Shareholders who are not affiliated with the Sponsor may be exposed to greater risk as a result of becoming stockholders of Pubco through the Business Combination rather than acquiring shares of Pubco Class A Stock directly in an underwritten public offering as a result of the differences between the two transaction structures, including that the Business Combination did not involve an independent due diligence review by an underwriter and that the Sponsor has conflicts of interest in connection with the Business Combination.

Because there is no independent third-party underwriter involved in the Business Combination or the issuance of Pubco Stock in connection therewith, investors will not receive the benefit of any outside independent review of the respective finances and operations of MLAC and Pubco. Underwritten public offerings of securities conducted by a licensed broker-dealer are subjected to a due diligence review by the underwriter or dealer manager to satisfy statutory duties under the Securities Act, the rules of Financial Industry Regulatory Authority, Inc. and the national securities exchange where such securities are listed. Additionally, underwriters or dealer-managers conducting such public offerings are subject to liability for any material misstatements or omissions in a registration statement filed in connection with the public offering. As no such review will be conducted in connection with the Business Combination, MLAC Shareholders must rely on the information in this proxy statement/prospectus and will not have the benefit of an independent review and investigation of the type normally performed by an independent underwriter in a public security offering.

If Pubco became a public company through an underwritten public offering, the underwriters would be subject to liability under Section 11 of the Securities Act for material misstatements and omissions in the initial public offering registration statement. In general, an underwriter is able to avoid liability under Section 11 if it can prove that, it “had, after reasonable investigation, reasonable ground to believe and did believe, at the time the registration statement became effective, that the statements therein (other than the audited financial statements) were true and that there was no omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading.” In order to fulfill its duty to conduct a “reasonable investigation,” an underwriter will, in addition to conducting a significant amount of due diligence on its own, usually require that an issuer’s independent registered public accounting firm provide a comfort letter with respect to certain numbers included in the registration statement and will require the law firm for the issuer to include in its legal opinion to the underwriters, a statement that such counsel is not aware of any material misstatements or omissions in the initial public offering registration statement (a ”Counsel Negative Assurance Statement”). Auditor comfort letters and Counsel Negative Assurance Statements are generally not required in connection with private companies going public through a merger with a SPAC, such as MLAC.

In addition, the amount of due diligence conducted by MLAC and its advisors in connection with the Business Combination may not be as great as would have been undertaken by an underwriter in connection with an initial public offering of Pubco. Accordingly, it is possible that defects in the Company’s business or problems with the Company’s management that would have been discovered if Pubco conducted an underwritten public offering will not be discovered in connection with the Business Combination, which could adversely affect the market price of Pubco Class A Stock.

Unlike an underwritten initial public offering, the initial trading of Pubco Class A Stock will not benefit from the book-building process undertaken by underwriters that helps to inform efficient price discovery with respect to opening trades of newly listed shares and underwriter support to help stabilize, maintain or affect the public price of the new issue immediately after listing. The lack of such a process in connection with the listing of Pubco Class A Stock on applicable national securities exchange could result in diminished investor demand, inefficiencies in pricing and a more volatile public price for Pubco Class A Stock during the period immediately following the listing.

Furthermore, the Sponsor and its Affiliates have interests in the Business Combination that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders. Such interests may have influenced the MLAC Board in making their recommendation that MLAC Shareholders vote in favor of the Business Combination Proposal and the other Proposals. In addition, in the event the Business Combination is completed, the value of the MLAC Founder Shares will be significantly greater than the amount the Sponsor paid to purchase such shares, even if after consummation of the Business Combination the trading price of Pubco Class A Stock materially declines. See “Since the Sponsor and its Affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders, a conflict of interest may have existed in determining whether the Business Combination with Pubco and the Company is appropriate as MLAC’s initial business combination. Such interests include that the Sponsor and Affiliates will lose its entire investment in MLAC if the Business Combination is not completed or any other business combination is not completed” and the section of this proxy statement/prospectus entitled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and its Affiliates in the Business Combination.” See also “The value of the MLAC Founder Shares following completion of the Business Combination is likely to be substantially higher than the nominal price

87

paid for them, even if the trading price of shares of Pubco Class A Stock at such time is substantially less than $10.00 per share, which may create an economic incentive for the MLAC management team to pursue and consummate the Business Combination which differs from the Public Shareholders.”

If MLAC is deemed to be an investment company under the Investment Company Act, MLAC may be required to institute burdensome compliance requirements and its activities may be restricted, which may make it difficult for MLAC to complete the Business Combination.

The SEC’s adopting release with respect to the 2024 SPAC Rules provided guidance relating to the potential status of SPACs as investment companies subject to regulation under the Investment Company Act and the regulations thereunder. Whether a SPAC is an investment company is dependent on specific facts and circumstances and SPAC can give no assurance that a claim will not be made that SPAC has been operating as an unregistered investment company. See also “Risk Factors — Risks Related to the Business and Strategy of Pubco — Regulatory changes classifying AVAX as a “security” could lead to Pubco’s classification as an “investment company” under the Investment Company Act and could adversely affect the market price of AVAX and the market price of shares of Pubco Class A Stock.”

If MLAC is deemed to be an investment company under the Investment Company Act, MLAC’s activities may be restricted, including (i) restrictions on the nature of its investments; and (ii) restrictions on the issuance of securities, each of which may make it difficult for MLAC to complete the Business Combination. In addition, MLAC may have to impose burdensome requirements, including: (i) registration as an investment company; (ii) adoption of a specific form of corporate structure; and (iii) reporting, record keeping, voting, proxy and disclosure requirements and other rules and regulations.

In order not to be regulated as an investment company under the Investment Company Act, unless MLAC can qualify for an exclusion, MLAC must ensure that it is engaged primarily in a business other than investing, reinvesting or trading in securities and that its activities do not include investing, reinvesting, owning, holding or trading “investment securities” constituting more than 40% of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. MLAC is mindful of the SEC’s investment company definition and guidance and does not intend to complete an initial business combination with an investment company, or to acquire minority interests in other businesses or “investment securities” exceeding the permitted threshold.

To mitigate the risk that its business activities will subject MLAC to the Investment Company Act, MLAC’s proceeds held in the Trust Account have only been invested in U.S. government treasury obligations with a maturity of 185 days or less or in any open-ended investment company that holds itself out as money market funds selected by MLAC meeting certain conditions of paragraphs (d)(2), (d)(3) and (d)(4) of Rule 2a-7 under the Investment Company Act, which invest only in direct U.S. government treasury obligations. The holding of the assets in the Trust Account in this form is intended to be temporary and for the sole purpose of facilitating the Business Combination or another business combination. To mitigate the risk that MLAC might be deemed to be an investment company for purposes of the Investment Company Act, which risk increases the longer that MLAC holds investments in the Trust Account, MLAC may, at any time, instruct CST, as trustee of the Trust Account, to liquidate the investments held in the Trust Account and instead to hold the funds in the Trust Account in cash or in an interest bearing demand deposit account at a bank. MLAC’s cash if held in these accounts may exceed any applicable FDIC insurance limits. Should events, including limited liquidity, defaults, non-performance or other adverse developments occur with respect to the banks or other financial institutions that hold MLAC’s funds, or that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, the value of the assets in the Trust Account could be impaired, which could have a material impact on MLAC’s operating results, liquidity, financial condition and prospects. For example, on March 10, 2023, the FDIC announced that Silicon Valley Bank had been closed by the California Department of Financial Protection and Innovation. MLAC cannot guarantee that the banks or other financial institutions that will hold MLAC’s funds will not experience similar issues in the future.

Pursuant to the investment management trust agreement between MLAC and CST, CST is not permitted to invest in securities or assets other than as described above. By restricting the investment of the proceeds to these instruments, and by having a business plan targeted at acquiring and growing businesses for the long term (rather than on buying and selling businesses in the manner of a merchant bank or private equity fund), MLAC intends to avoid being deemed an “investment company” within the meaning of the Investment Company Act. The MLAC IPO was not intended for persons who were seeking a return on investments in government securities or investment securities. The Trust Account is intended solely as a temporary depository for funds pending the earliest to occur of: (i) the completion of the Business Combination or another business combination; (ii) the redemption of any Public Shares properly submitted in connection with a shareholder vote to amend the MLAC Memorandum and Articles (x) in a manner that would

88

affect the substance or timing of its obligation to redeem 100% of the Public Shares if MLAC does not complete the Business Combination or another business combination by the end of the Combination Period; or (y) with respect to any other provision relating to the rights of Public Shareholders or pre-business combination activity; or (iii) absent the consummation of a business combination by the end of the Combination Period, return of the funds held in the Trust Account to Public Shareholders as part of MLAC’s redemption of the Public Shares.

MLAC cannot guarantee that it will not be deemed to be an investment company and thus subject to the Investment Company Act. Notwithstanding MLAC’s investment activities or the mitigation measures included herein, MLAC could still be deemed to be or have been an investment company at any time since the MLAC IPO.

If MLAC were deemed to be subject to the Investment Company Act, compliance with these additional regulatory burdens would require additional expenses for which MLAC has not allotted funds and may hinder its ability to complete the Business Combination or may result in its liquidation. If MLAC is unable to complete the Business Combination or any other business combination, Public Shareholders may only receive approximately $10.62 per share on the liquidation of the Trust Account (which is the approximate amount per Public Share based on the Trust Account balance as of May 4, 2026, including interest earned on the funds held in the Trust Account but less taxes payable), and Public Shareholders would also lose the possibility of an investment opportunity in Pubco or another potential business combination.

Changes in laws or regulations (including the adoption of policies by governing administrations), or a failure to comply with any laws and regulations, may adversely affect MLAC’s business, including MLAC’s ability to complete the Business Combination.

MLAC is subject to laws and regulations enacted by national, regional and local governments. These governing bodies may seek to change laws and regulations, as well as adopt new policies, including tariffs and other economic policies, that could negatively impact MLAC or Pubco. MLAC is also required to comply with certain SEC and other legal requirements and numerous complex tax laws. Compliance with, and monitoring of, applicable laws and regulations may be difficult, time consuming and costly. Those laws and regulations and their interpretation and application may also change from time to time and those changes could have a material adverse effect on MLAC’s business, investments and results of operations. In addition, a failure to comply with applicable laws or regulations, as interpreted and applied, could have a material adverse effect on MLAC’s business.

On January 24, 2024, the SEC adopted the 2024 SPAC Rules which became effective on July 1, 2024, requiring, among other items, (i) additional disclosures relating to SPAC sponsors and related persons; (ii) additional disclosures relating to SPAC business combination transactions; (iii) additional disclosures relating to dilution and to conflicts of interest involving sponsors and their affiliates in both SPAC initial public offerings and business combination transactions; (iv) additional disclosures regarding projections included in SEC filings in connection with proposed business combination transactions; and (v) the requirement that both the SPAC and its acquisition target be co-registrants for business combination registration statements.

In addition, the SEC’s adopting release provided the SPAC Guidance describing circumstances in which a SPAC could become subject to regulation under the Investment Company Act, including its duration, asset composition, business purpose and the activities of the SPAC and its management team in furtherance of such goals.

Compliance with the 2024 SPAC Rules and the SPAC Guidance may increase the costs of, and the time needed to complete, the Business Combination.

If the Business Combination is not approved and MLAC does not consummate another initial business combination by the end of the Combination Period, then the MLAC Ordinary Shares held by the Sponsor and its Affiliates will become worthless and the expenses it has incurred will not be reimbursed. These interests may have influenced its decision to approve the Business Combination.

The Sponsor beneficially owns the MLAC Class B Ordinary Shares and MLAC Private Placement Shares that it purchased for an aggregate of $4,975,000 prior to, or simultaneously with, the MLAC IPO, and the Sponsor has no redemption rights with respect to these MLAC Class B Ordinary Shares. If the Business Combination with Pubco or another business combination is not completed by the end of the Combination Period, these securities will be worthless, and MLAC would be unlikely to be able to repay the MLAC Working Capital Loan if any is outstanding. Certain directors and executive officers of MLAC have indirect economic interests in the Sponsor and accordingly, they may have an incentive to pursue and consummate an initial business combination, even if that business combination were with an acquisition target or on terms less favorable to Public Shareholders than liquidation. See also “The value of

89

the MLAC Founder Shares following completion of the Business Combination is likely to be substantially higher than the nominal price paid for them, even if the trading price of shares of Pubco Class A Stock at such time is substantially less than $10.00 per share, which may create an economic incentive for the MLAC management team to pursue and consummate the Business Combination which differs from the Public Shareholders.”

In addition, MLAC’s officers and directors and their affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on MLAC’s behalf, such as identifying and investigating possible acquisition targets and business combinations. These expenses will be repaid upon completion of the Business Combination with Pubco. However, if MLAC fails to consummate the Business Combination or another initial business combination, they will not have any claim against the Trust Account for repayment or reimbursement.

Accordingly, MLAC may not be able to repay or reimburse these amounts if the Business Combination is not completed. As of December 31, 2025, no such amounts had been incurred by any of MLAC’s officers, directors or their affiliates.

For additional information, see the section of this proxy statement/prospectus entitled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and its Affiliates in the Business Combination.”

These financial interests may have influenced the decision of MLAC’s directors to approve the Business Combination with Pubco and to continue to pursue such Business Combination. In considering the recommendations of the MLAC Board to vote for each of the Proposals, MLAC Shareholders should consider these interests.

If third parties bring claims against MLAC, the proceeds held in the Trust Account could be reduced and the per-share redemption amount received by Public Shareholders could be less than $10.62 per share (based on the Trust Account balance as of May 4, 2026, and including interest earned on the funds held in the Trust Account but less taxes payable).

MLAC’s placing of funds in the Trust Account may not protect those funds from third party claims against MLAC. Although MLAC will seek to have all vendors, service providers (except for MLAC’s independent registered public accounting firm), prospective target businesses and other entities with which MLAC does business execute agreements with MLAC waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of Public Shareholders, such parties may not execute such agreements, or even if they execute such agreements they may not be prevented from bringing claims against the Trust Account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain advantage with respect to a claim against MLAC’s assets, including the funds held in the Trust Account. If any third party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, MLAC’s management will consider whether competitive alternatives are reasonably available to MLAC and will only enter into an agreement with such third party if management believes that such third party’s engagement would be in the best interests of MLAC under the circumstances. The underwriters of the MLAC IPO as well as MLAC’s registered independent public accounting firm did not execute agreements with MLAC waiving such claims to the monies held in the Trust Account.

Examples of possible instances where MLAC may engage a third party that refuses to execute a waiver include the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with MLAC and will not seek recourse against the Trust Account for any reason. Upon redemption of MLAC Public Shares, if MLAC is unable to complete the Business Combination or another initial business combination within the prescribed timeframe, or upon the exercise of a redemption right in connection with the Business Combination, MLAC will be required to provide for payment of claims of creditors that were not waived that may be brought against MLAC within the 10 years following redemption.

Accordingly, the per-share redemption amount received by Public Shareholders could be less than the $10.62 redemption price as of May 4, 2026, due to claims of such creditors. Pursuant to the Insider Letter, the Sponsor has agreed that it will be liable to MLAC if and to the extent any claims by a third party for services rendered or products sold to MLAC (except for MLAC’s independent auditors), or a prospective target business with which MLAC has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per

90

Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under MLAC’s indemnity of the underwriters of MLAC IPO against certain liabilities, including liabilities under the Securities Act. However, MLAC has not asked the Sponsor to reserve for such indemnification obligations, nor has MLAC independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and MLAC believes that the Sponsor’s only assets are securities of MLAC. Therefore, MLAC cannot assure the Public Shareholders that the Sponsor would be able to satisfy those obligations. As a result, if any such claims were successfully made against the Trust Account, the funds available for the Business Combination and redemptions could be reduced to less than $10.05 per Public Share. In such event, MLAC may not be able to complete the Business Combination, and you would receive such lesser amount per share in connection with any redemption of your Public Shares. None of MLAC’s officers or directors will indemnify MLAC for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Additionally, if MLAC is forced to file a bankruptcy case or an involuntary bankruptcy case is filed against it which is not dismissed, or if MLAC otherwise enters compulsory or court supervised liquidation, the proceeds held in the Trust Account could be subject to applicable bankruptcy law and may be included in its bankruptcy estate and subject to the claims of third parties with priority over the claims of the Public Shareholders. To the extent any bankruptcy claims deplete the Trust Account, MLAC may not be able to return to its Public Shareholders $10.62 per share (which is the approximate amount per Public Share based on the Trust Account balance as of May 4, 2026, and including interest earned on the funds held in the Trust Account but less taxes payable).

MLAC Shareholders may be held liable for claims by third parties against MLAC to the extent of distributions received by them.

If MLAC is unable to complete the Business Combination with the Company or another business combination by the end of the Combination Period, MLAC will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem 100% of the issued and outstanding Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to MLAC (net of taxes payable and less up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of MLAC’s remaining shareholders and the MLAC Board, dissolve and liquidate, subject in each case to its obligations under Cayman Islands laws to provide for claims of creditors and the requirements of other applicable law. MLAC cannot assure Public Shareholders that it will properly assess all claims that may be potentially brought against MLAC.

If MLAC is forced to enter into an insolvent liquidation, any distributions received by MLAC Shareholders could be viewed as an unlawful payment if it was proved that immediately following the date on which the distribution was made, MLAC’s liabilities exceeded its assets, or it was unable to pay its debts as they fall due in the ordinary course of business. As a result, a liquidator could seek to recover all amounts received by MLAC Shareholders. Furthermore, MLAC’s directors may be viewed as having breached their fiduciary duties to MLAC or MLAC’s creditors and/or may have acted in bad faith, thereby exposing themselves and MLAC to claims, by paying Public Shareholders from the Trust Account prior to addressing the claims of creditors. There is no assurance that claims will not be brought against MLAC for these reasons. MLAC and its directors and officers who knowingly and willfully authorized or permitted any distribution to be paid out of the Trust Account while MLAC was unable to pay its debts as they fall due in the ordinary course of business would be guilty of an offense and may be liable to a fine of approximately $18,292.68 and to imprisonment for five years in the Cayman Islands.

MLAC’s directors may decide not to enforce the indemnification obligations of the Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to the Public Shareholders.

In the event that the proceeds in the Trust Account are reduced below the lesser of (i) $10.05 per share and (ii) the actual amount per share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.05 per share due to reductions in the value of the assets in the Trust Account, in each case net of the interest which may be withdrawn to pay taxes, and the Sponsor asserts that it is unable to satisfy its obligations or that it has no indemnification obligations related to a particular claim, MLAC’s independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations.

91

While MLAC currently expects that its independent directors would take legal action on MLAC’s behalf against the Sponsor to enforce its indemnification obligations to MLAC, it is possible that MLAC’s independent directors in exercising their business judgment and subject to their fiduciary duties may choose not to do so in any particular instance if, for example, the cost of such legal action is deemed by the independent directors to be too high relative to the amount recoverable or if the independent directors determine that a favorable outcome is not likely. If MLAC’s independent directors choose not to enforce these indemnification obligations, the amount of funds in the Trust Account available for distribution to the Public Shareholders may be reduced below $10.62 per share (which is the approximate amount per Public Share based on the Trust Account balance as of May 4, 2026, and including interest earned on the funds held in the Trust Account but less taxes payable).

MLAC may not have sufficient funds to satisfy indemnification claims of its directors and officers.

MLAC has agreed to indemnify its officers and directors to the fullest extent permitted by law. However, its officers and directors have agreed to waive any right, title, interest or claim of any kind in or to any monies in the Trust Account and to not seek recourse against the Trust Account for any reason whatsoever. Accordingly, any indemnification provided will be able to be satisfied by MLAC only if (i) MLAC has sufficient funds outside of the Trust Account or (ii) MLAC consummates the Business Combination or another business combination. MLAC’s obligation to indemnify its officers and directors may discourage MLAC Shareholders from bringing a lawsuit against its officers or directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against its officers and directors, even though such an action, if successful, might otherwise benefit MLAC and the MLAC Shareholders. Furthermore, an MLAC Shareholder’s investment may be adversely affected to the extent MLAC pays the costs of settlement and damage awards against its officers and directors pursuant to these indemnification provisions.

Following the Business Combination, Pubco’s business activities may be subject to review or approval by regulatory authorities pursuant to certain U.S. or foreign laws or regulations.

Certain business activities are subject to review or approval by regulatory authorities pursuant to certain U.S. or foreign laws or regulations. In the event that such regulatory approval or clearance is not obtained, or such approval or clearance is subject to conditions that are not acceptable to Pubco, Pubco may not be able to engage in such activities.

Among other things, the offering of certain financial products may be subject to state, federal or foreign laws or regulations. U.S. or foreign laws or regulations may also affect our ability to acquire interests in other businesses. In the United States, certain mergers that may affect competition may require filings and review by the Department of Justice and the Federal Trade Commission, and investments or acquisitions that may affect national security are subject to review by the Committee on Foreign Investment in the United States (“CFIUS”). CFIUS is an interagency committee authorized to review certain transactions involving foreign investment in the United States by foreign persons in order to determine the effect of such transactions on the national security of the United States.

The Sponsor and its Affiliates have entered into letter agreements with MLAC, and the Sponsor has entered into the Sponsor Support Agreement with MLAC and Pubco, in each case, which requires them to vote in favor of the Business Combination, regardless of how the Public Shareholders vote.

The Sponsor and its Affiliates have entered the Insider Letter, and the Sponsor has entered into the Sponsor Support Agreement with MLAC and Pubco, pursuant to which, among other things, they have agreed to vote all of their MLAC Ordinary Shares in favor of any proposed business combination, except that any Public Shares that they may purchase in compliance with the requirements of Rule 14e-5 under the Exchange Act would not be voted in favor of approving the Business Combination. As of the date of this proxy statement/prospectus, the Sponsor owns approximately 24.8% of the issued and outstanding MLAC Ordinary Shares.

To pass, each of the Business Combination Proposal, the Nasdaq Proposal, the Director Election Proposal and the Adjournment Proposal requires an ordinary resolution of MLAC Shareholders, which requires the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). To pass, the Merger Proposal requires a special resolution of MLAC Shareholders, which requires the affirmative vote of at least two-thirds of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). MLAC Shareholders are also being asked to approve by way of ordinary resolutions, on a non-binding advisory basis, the Domestication and

92

Organizational Documents Proposals. Although the MLAC Board is asking MLAC Shareholders to approve the Domestication and Organizational Documents Proposals on the non-binding advisory basis, regardless of the outcome of the non-binding advisory vote on the Domestication and Organizational Documents Proposals, the Amended and Restated Certificate of Incorporation and Pubco’s Amended and Restated Bylaws will take effect upon the Closing if the Shareholder Approval Matters are approved.

As a result, with respect to each Proposal that require approval of MLAC Shareholders by an ordinary resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 7,813,751, or 34.0%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposals in order to have such Proposals approved.

With respect to the Merger Proposal which requires approval of MLAC Shareholders by a special resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 12,979,167, or 56.4%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposal in order to have such Proposal approved.

Accordingly, the agreement by the Sponsor to vote its MLAC Ordinary Shares in favor of the Business Combination increases the likelihood that MLAC will receive the requisite MLAC Shareholder approval for the Business Combination.

Because MLAC is seeking to obtain shareholder approval of the Business Combination, the Sponsor and its Affiliates and their respective affiliates may elect to purchase Public Shares from Public Shareholders, subject to any limitations under Rule 14e-5 under the Exchange Act, which may influence the vote on the Business Combination and reduce the public “float” of MLAC Class A Ordinary Shares.

MLAC is seeking to obtain shareholder approval of the Business Combination. Subject to compliance with applicable securities laws, including Rule 14e-5 under the Exchange Act, the Sponsor, MLAC’s directors and officers and their affiliates may purchase Public Shares in privately negotiated transactions or in the open market prior to the record date of the Meeting, although they are under no obligation or duty to do so.

Any such purchases shall be effected at a price per share no higher than the amount per share a Public Shareholder would receive if it elected to have its Public Shares redeemed in connection with the Business Combination. However, they have no current commitments, plans or intentions to engage in such transactions and have not formulated any terms or conditions for any such transactions. None of the funds in the Trust Account will be used to purchase Public Shares in such transactions. Such a purchase may include a contractual acknowledgment that such shareholder, although still the record holder of Public Shares is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Sponsor, MLAC’s directors and officers or any of their affiliates purchase Public Shares in privately negotiated transactions from Public Shareholders who have already elected to exercise their redemption rights, such selling shareholders would be required to revoke their prior elections to redeem their Public Shares. It is intended that, if Rule 10b-18 under the Exchange Act would apply to such purchases, then such purchases will comply with Rule 10b-18 under the Exchange Act, to the extent it applies, which provides a safe harbor for purchases made under certain conditions, including with respect to timing, pricing and volume of purchases. Any such purchases, together with the MLAC Ordinary Shares currently owned by the Sponsor, could influence the vote on the Business Combination or otherwise result in the completion of the Business Combination that may not otherwise have been possible.

Additionally, at any time at or prior to the consummation of the Business Combination, subject to applicable securities laws (including with respect to material non-public information), the Sponsor, MLAC’s directors and officers and their affiliates may enter into transactions with investors and others to provide them with incentives to acquire Public Shares or not to elect to have their Public Shares redeemed. However, they have no current commitments, plans or intentions to engage in such transactions and have not formulated any terms or conditions for any such transactions. None of the funds in the Trust Account will be used to purchase public shares in such transactions.

If such purchases are made, the public “float” of MLAC Class A Ordinary Shares may be reduced and the number of beneficial holders of MLAC Class A Ordinary Shares may be reduced, which may make it difficult to maintain or obtain the quotation, listing or

93

trading of Public Shares on Nasdaq or another securities exchange. Any such purchases will be reported pursuant to Section 13 and Section 16 of the Exchange Act to the extent such purchasers are subject to such reporting requirements.

Additionally, in the event the Sponsor, MLAC’s directors and officers or their affiliates were to purchase Public Shares from Public Shareholders, such purchases would be structured in compliance with the requirements of Rule 14e-5 under the Exchange Act to the extent such rule is applicable including, in pertinent part, through adherence to the following:

• MLAC would disclose in this proxy statement/prospectus the possibility that the Sponsor, MLAC’s directors and officers or their affiliates may purchase Public Shares from Public Shareholders outside the redemption process, along with the purpose of such purchases;

• if the Sponsor, MLAC’s directors and officers or their affiliates were to purchase Public Shares from Public Shareholders, they would do so at a price no higher than the price offered through the redemption process;

• MLAC would include in this proxy statement/prospectus a representation that any of the Public Shares purchased by the Sponsor, MLAC’s directors and officers or their affiliates would not be voted in favor of approving the Business Combination;

• the Sponsor, MLAC’s directors and officers or their affiliates would either not possess any redemption rights with respect to such Public Shares or they would waive such rights; and

• MLAC would disclose in a Form 8-K filed prior to the Extraordinary General Meeting, the following items, to the extent material:

• the amount of Public Shares purchased outside of the redemption offer by the Sponsor, MLAC’s directors and officers or their affiliates, along with the average purchase price;

• the purpose of the purchases by the Sponsor, MLAC’s directors and officers or their affiliates;

• the impact, if any, of the purchases by the Sponsor, MLAC’s directors and officers or their affiliates on the likelihood that the Business Combination will be approved at the Extraordinary General Meeting;

• the identities of the MLAC Shareholders who sold Public Shares to the Sponsor, MLAC’s directors and officers or their affiliates (if not purchased in the open market) or the nature of the MLAC Shareholders (e.g., 5% shareholders) who sold Public Shares to the Sponsor, MLAC’s directors and officers or their affiliates; and

• the number of Public Shares for which MLAC has received redemption requests pursuant to its redemption offer as of a date shortly prior to the filing date of the Form 8-K.

MLAC, Pubco and Seller will incur transaction costs in connection with the Business Combination.

Each of the parties to the Business Combination Agreement has incurred and expects that it will incur significant, non-recurring costs in connection with the consummation of the Business Combination. Pubco may also incur additional costs to retain key employees. MLAC and Pubco will also incur significant legal, financial advisor, accounting, banking and consulting fees, fees relating to regulatory filings and notices, SEC filing fees, printing and mailing fees and other costs associated with the Business Combination. MLAC, Pubco and the Company estimate that they will incur $16.7 million in aggregate transaction costs. As preliminary estimates, MLAC expects to incur approximately $1.8 million in transaction costs (assuming that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination), and Pubco and Seller together expect to incur $14.8 million of estimated transaction costs for placement agent, legal, accounting, and advisory fees incurred as part of the Business Combination. Some of these costs are payable regardless of whether the Business Combination is completed.

Risks Related to Ownership of Pubco Stock Following the Business Combination.

Seller, whose interests may conflict with yours, can individually exercise significant influence over Pubco. You will have no voting rights of Pubco Class A Stock except as required by the DGCL and the concentrated ownership of Pubco Stock may prevent you and other shareholders from influencing significant decisions in the very limited circumstances in which the DGCL will give you the right to vote and may prevent or discourage unsolicited acquisition proposals or offers for Pubco Stock, and that may adversely affect the trading price of Pubco Class A Stock.

Upon the Closing, assuming, among other things, that all of the Company Units are redeemed in exchange for shares of Pubco Class A Stock, that no shares of Pubco Class A Stock are issued pursuant to the Incentive Plan and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements, Seller Related Parties and Astral will beneficially own (i) approximately 15.7% of the issued and outstanding shares of Pubco Class A Stock, assuming no redemption of Public Shares in connection with the Business Combination, or (ii) 24.8% of the issued and outstanding Pubco Class A Stock, assuming the maximum Public Shares are redeemed in connection with the Business Combination. Further, only Pubco Class B Stock will have voting rights at Pubco and all shares of Pubco Class B Stock will be owned by Seller. For so long as Seller holds a significant portion of the voting interests of Pubco through its ownership of Pubco Class B Stock, it will have the ability to significantly influence decision-making with respect to Pubco’s business direction and policies.

The shares of Pubco Class B Stock will not be transferable and will be canceled, pro rata, upon any transfer of shares of Pubco Class A Stock by Seller to any third party (other than its affiliates). Transfers of shares of Pubco Class A Stock held by Seller will be subject to the provision of the Lock-Up Agreement and transfer of shares of Pubco Class A Stock held by the Sponsor will be subject to the provision of the Insider Letter (as amended prior to Closing pursuant to the Sponsor Support Agreement), pursuant to which Seller and the Sponsor will agree not to, subject to certain exceptions, transfer their shares of Pubco Class A Stock until the earlier of (i) the one-year anniversary of the Closing and (ii) the date on which Pubco consummates a liquidation, merger, capital stock exchange, reorganization or other similar transaction after the Closing which results in all of Pubco’s shareholders having the right to exchange their shares of Pubco Stock for cash, securities or other property. The shares of Pubco Class A Stock shall acquire full voting rights upon cancellation of all shares of Pubco Class B Stock. Pubco cannot predict when Pubco Class A Stock may gain voting rights, if at all.

Seller is also entitled to board designation rights under the Proposed Organizational Documents. Matters over which Seller may individually, directly or indirectly, exercise significant influence following the Closing include (subject to any non-waivable voting rights afforded to the holders of Pubco Class A Stock under the DGCL): (i) the election of the directors on the Pubco Board; (ii) business combinations and other merger transactions requiring shareholder approval, including proposed transactions that would result in Pubco’s shareholders receiving a premium price for their shares; (iii) amendments to the Amended and Restated Certificate of Incorporation, and (iv) increases or decreases in the size of the Pubco Board. Such concentrated control may prevent or discourage unsolicited acquisition proposals or offers for Pubco Stock that you may feel are in your best interest as one of Pubco’s shareholders. As a result, such concentrated control may adversely affect the market price of Pubco Class A Stock.

Seller, through its voting control of Pubco, is in a position to control actions that require shareholder approval and may make decisions that are adverse to other shareholders.

At Closing, Seller will own all of the outstanding Pubco Class B Stock. As a result, Seller will have the ability to exercise control over certain decisions requiring shareholder approval, including the election of directors, amendments to the Amended and Restated Certificate of Incorporation and approval of significant corporate transactions, such as a merger or other sale of Pubco or our assets. In addition, the Pubco Board will consist of one (1) or more members, each of whom shall be a natural person. Accordingly, Seller will have significant influence over Pubco and Pubco’s decisions, including the appointment of management and any other action requiring a vote of the Pubco Board. In addition, this concentration of ownership may have the effect of delaying, preventing or deterring a change in control of us and may negatively affect the market price of Pubco Class A Stock.

95

At Closing, holders of Pubco Class A Stock will not have voting rights. Other than as required by applicable law, the holders of shares of Pubco Class A Stock shall only acquire full voting rights upon cancellation of all shares of Pubco Class B Stock. The shares of Pubco Class B Stock will be canceled ‘upon any transfer of shares of Pubco Class A Stock by Seller to any third party (other than its affiliates). Transfers of Pubco Class A Stock will be subject to the provision of the Lock-Up Agreement that Pubco will enter into at Closing, pursuant to which Seller will agree not to, subject to certain exceptions, transfer its shares of Pubco Stock until the earlier of (i) the one-year anniversary of the Closing and (ii) the date on which Pubco consummates a liquidation, merger, capital stock exchange, reorganization or other similar transaction after the Closing which results in all of Pubco’s shareholders having the right to exchange their shares of Pubco Stock for cash, securities or other property. Pubco cannot predict when holders of Pubco Class A Stock may gain voting rights, if at all.

Securities of companies formed through mergers with SPACs, such as Pubco, may experience a material decline in price relative to the share price of the SPAC prior to such merger.

MLAC issued MLAC Class A Ordinary Shares as part of the MLAC Public Units for $10.00 per unit upon the closing of the MLAC IPO. As with other SPACs, each Public Share issued in the MLAC IPO carries a right to redeem such share for a pro rata portion of the proceeds held in the Trust Account prior to the Closing. As of May 4, 2026, the redemption price per Public Share was approximately $10.62, which is the approximate redemption amount per Public Share based on the Trust Account balance as of May 4, 2026. Following the Closing, the shares of Pubco Class A Stock outstanding will no longer have any such redemption right and may be dependent upon the fundamental value of Pubco, as well as other relevant factors such as market conditions and trading multiples, and the securities of other companies formed through mergers with SPACs in recent years, and may be significantly less than $10.00 per share.

Volatility in Pubco’s share price could subject Pubco to securities class action litigation.

The market price of the shares of Pubco Class A Stock may be volatile and, in the past, companies that have experienced volatility in the market price of their shares have been subject to securities class action litigation. Pubco may be the target of this type of litigation and investigations. Securities litigation against Pubco could result in substantial costs and divert management’s attention from other business concerns, which could seriously harm Pubco’s business.

Beginning in January 2022, there has been a precipitous drop in the market values of companies formed through mergers involving SPACs. Accordingly, securities of companies such as Pubco may be more volatile than other securities and may involve special risks. These risks include inflationary pressures, increases in interest rates and other adverse economic and market forces which have contributed to these drops in market value for SPACs. As a result, the Public Shares are subject to potential downward pressures, which may result in high levels of exercises of redemptions rights, reducing the cash available from the Trust Account. If there are substantial redemptions by Public Shareholders in connection with the Business Combination, there will be a lower public float of Pubco Class A Stock following the Closing, which may cause volatility in the price of our securities and adversely impact our ability to secure financing following the Closing.

Currently, there is no public market for the shares of Pubco Class A Stock. Public Shareholders cannot be sure about whether the shares of Pubco Class A Stock will develop an active trading market or whether Pubco is able to maintain the listing of Pubco Class A Stock in the future even if Pubco is successful in listing Pubco Class A Stock on Nasdaq or any other national securities exchange, which could limit investors’ ability to make transactions in shares of Pubco Class A Stock and subject Pubco to additional trading restrictions.

As part of the Business Combination, each outstanding MLAC Class A Ordinary Share (including the MLAC Class A Ordinary Shares issued upon conversion of the outstanding MLAC Class B Ordinary Shares) will be converted automatically into one share of Pubco Class A Stock. Pubco is a newly formed entity and prior to this transaction it has not issued any securities in the U.S. markets or elsewhere nor has there been extensive information about it, its businesses or its operations publicly available. MLAC and Pubco have agreed to cause the shares of Pubco Class A Stock to be issued in the Business Combination to be approved for listing on Nasdaq, or any other national securities exchange, prior to the effective time of the Business Combination. MLAC cannot assure Public Shareholders that Pubco will be able to meet the initial listing requirements. However, Pubco may be unsuccessful in listing Pubco Class A Stock on Nasdaq, or any other national securities exchange, and even if successful, Pubco may be unable to maintain the listing of Pubco Class A Stock in the future. A successful listing also does not ensure that a market for the shares of Pubco Class A Stock will develop or the price at which the shares will trade. No assurance can be provided as to the demand for or trading price of

96

the shares of Pubco Class A Stock following the Closing and the shares of Pubco Class A Stock may trade at a price less than the current market price of the MLAC Class A Ordinary Shares.

If Pubco fails to meet the initial listing requirements and Nasdaq or another national securities exchange does not list its shares of Pubco Class A Stock on its exchange, none of the parties to the Business Combination Agreement would be required to consummate the Business Combination. In the event that all such parties elected to waive this condition, and the Business Combination were consummated without shares of Pubco Class A Stock being listed on Nasdaq or on another national securities exchange, Pubco could face significant material adverse consequences, including:

• a limited availability of market quotations for shares of Pubco Class A Stock;

• reduced liquidity for shares of Pubco Class A Stock;

• to the extent that Pubco does not qualify for any of the other penny stock exemptions from under the applicable provisions of Rule 3a51-1 under the Exchange Act, a determination that shares of Pubco Class A Stock are “penny stocks” which will require brokers trading in shares of Pubco Class A Stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for shares of Pubco Class A Stock;

• a limited amount of news and analyst coverage; and

• a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” If shares of Pubco Class A Stock are not listed on Nasdaq or another national securities exchange, such shares would not qualify as covered securities and Pubco would be subject to regulation in each state in which Pubco offers its shares of Pubco Class A Stock because states are not preempted from regulating the sale of securities that are not covered securities.

Even if Pubco is successful in listing Pubco Class A Stock and developing a public market, there may not be enough liquidity in such market to enable Pubco shareholders to sell their shares of Pubco Class A Stock. If a public market for the shares of Pubco Class A Stock does not develop, investors may not be able to resell their shares of Pubco Class A Stock, rendering their shares illiquid and possibly resulting in a complete loss of their investment. Pubco cannot predict the extent to which investor interest in Pubco will lead to the development of an active, liquid trading market. The trading price of and demand for the shares of Pubco Class A Stock following completion of the Business Combination and the development and continued existence of a market and favorable price for the shares of Pubco Class A Stock will depend on a number of conditions, including the development of a market following, including by analysts and other investment professionals, the businesses, operations, results and prospects of Pubco, general market and economic conditions, governmental actions, regulatory considerations, legal proceedings and developments or other factors. These and other factors may impair the development of a liquid market and the ability of investors to sell shares at an attractive price. These factors also could cause the market price and demand for shares of Pubco Class A Stock to fluctuate substantially, which may limit or prevent investors from readily selling their shares and may otherwise affect negatively the price and liquidity of the shares of Pubco Class A Stock. Many of these factors and conditions are beyond the control of Pubco or shareholders of Pubco.

Reports published by analysts, including projections in those reports that differ from Pubco’s actual results, could adversely affect the price and trading volume of Pubco Stock.

Pubco’s management currently expects that securities research analysts will establish and publish their own periodic projections for its business. These projections may vary widely and may not accurately predict the results Pubco actually achieves. Pubco’s share price may decline if its actual results do not match the projections of these securities research analysts. Similarly, if one or more of the analysts who write reports on Pubco downgrades its stock or publishes inaccurate or unfavorable research about its business, its share price could decline. If one or more of these analysts ceases coverage of Pubco or fails to publish reports on it regularly, its share price or trading volume could decline. While Pubco’s management expects research analyst coverage, if no analysts commence coverage of Pubco, the trading price and volume for Pubco Stock could be adversely affected.

97

Pubco may or may not pay cash dividends in the foreseeable future.

Any decision to declare and pay dividends in the future will be made at the discretion of the Pubco Board and will depend on, among other things, applicable law, regulations, restrictions, Pubco’s and the Company’s respective results of operations, financial condition, cash requirements, contractual restrictions, the future projects and plans of Pubco and the Company and other factors that the Pubco Board may deem relevant. As a result, capital appreciation, if any, of Pubco Class A Stock will be an investor’s sole source of gain for the foreseeable future.

Pubco is a “controlled company” within the meaning of the Nasdaq Rules, and, as a result, will qualify for, and rely on, exemptions from certain corporate governance requirements. Our shareholders do not have the same protections afforded to shareholders of companies that are subject to such requirements.

Pubco expects to qualify as a “controlled company” as defined under the Nasdaq Rules, since Seller will beneficially own more than 50% of our total voting power. For so long as we remain a controlled company under this definition, we are also permitted to elect to rely on certain exemptions from corporate governance rules. As a result, you will not have the same protection afforded to shareholders of companies that are subject to these corporate governance requirements. For example, controlled companies:

• are not required to have a Board that is composed of a majority of “independent directors,” as defined under Nasdaq Rules;

• are not required to have a compensation committee that is composed entirely of independent directors; and

• are not required to have director nominations be made, or recommended to the full Board of Directors, by its independent directors or by a nominations committee that is composed entirely of independent directors.

These exemptions do not modify the requirement for a fully independent audit committee, which is permitted to be phased-in as follows: (1) one independent committee member at the time of consummation of the Transactions; (2) a majority of independent committee members within 90 days of consummation of the Transactions; and (3) all independent committee members within one year of consummation of the Transactions. Similarly, once we are no longer a “controlled company,” we must comply with the independent board committee requirements as they relate to the compensation committee and the nominating and corporate governance committee, on the same phase-in schedule as set forth above, with the trigger date being the date we are no longer a “controlled company” as opposed to our initial public offering date. Additionally, we will have 12 months from the date we cease to be a “controlled company” to have a majority of independent directors on our board of directors.

If we utilize the “controlled company” exemption, shareholders will not have the same protections afforded to shareholders of companies that are subject to all of the corporate governance requirements of the Nasdaq Rules. Our status as a controlled company could make our common stock less attractive to some investors or otherwise adversely affect its trading price.

The Amended and Restated Pubco Charter designates a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between us and our stockholders, and also provides that the federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, each of which may limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers, stockholders, or employees.

The Amended and Restated Pubco Charter provides that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action or proceeding asserting a claim for or based on a breach of a fiduciary duty owed by any of our current or former directors, stockholders, or officers or other employees to us or our stockholders, including a claim alleging the aiding and abetting of such a breach of fiduciary duty, (3) any action or proceeding asserting a claim against us or any current or former director, stockholder, or officer or other employee of us arising pursuant to, or seeking to enforce any right, obligation, or remedy under, any provision of the DGCL, the Amended and Restated Pubco Charter or our Amended and Restated Bylaws or (4) any action or proceeding related to or involving us or any current or former director, stockholder, or officer or other employee of us that is governed by the internal affairs doctrine; provided that, in the event that the Court of Chancery of the State of Delaware lacks subject matter jurisdiction over any such action or proceeding, the sole and exclusive forum for such action or proceeding shall be another state or federal court located within the State of Delaware, in each such case, unless the Court of Chancery (or such other state or federal court located within the State of Delaware, as applicable) has

98

dismissed a prior action by the same plaintiff asserting the same claims because such court lacked personal jurisdiction over an indispensable party named as a defendant therein.

The exclusive forum provision in the Amended and Restated Pubco Charter will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction.

Section 22 of the Securities Act establishes concurrent jurisdiction for federal and state courts over Securities Act claims. Accordingly, both state and federal courts have jurisdiction to hear such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our Amended and Restated Pubco Charter also provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States are the sole and exclusive forum for resolving any complaint asserting a cause or causes of action arising under the Securities Act.

Any person or entity purchasing or otherwise acquiring or holding any interest in any of our securities shall be deemed to have notice of and consented to the foregoing Amended and Restated Pubco Charter provisions. Although we believe these exclusive forum provisions benefit us by providing increased consistency in the application of Delaware law and federal securities laws in the types of lawsuits to which each applies, the exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum of its choosing for disputes with us or our current or former directors, officers, stockholders, or other employees, which may discourage lawsuits with respect to such claims against us and our current and former directors, officers, stockholders, or other employees. Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder as a result of our exclusive forum provisions.

Further, the enforceability of similar exclusive forum provisions in other companies’ organizational documents has been challenged in legal proceedings, and it is possible that a court of law may rule that these types of provisions are inapplicable or unenforceable if they are challenged in a proceeding or otherwise. If a court were to find the exclusive forum provisions contained in our Amended and Restated Pubco Charter to be inapplicable or unenforceable in an action, we may incur significant additional costs associated with resolving such dispute, as well as resolving such action in other jurisdictions, all of which may adversely affect our business, financial condition, and results of operations.

Because Pubco Class A Stock is non-voting, we and our stockholders are exempt from certain provisions of U.S. securities laws. This may limit the information available to holders of Pubco Class A Stock.

Because Pubco Class A Stock is non-voting, significant holders of Pubco Class A Stock are exempt from the obligation to file reports under Sections 13(d), 13(g), and 16 of the Exchange Act. These provisions generally require periodic reporting of beneficial ownership by significant stockholders. Our directors and officers are required to file reports under Section 16 of the Exchange Act. Our significant stockholders, other than directors and officers and the Seller Related Parties, are exempt from the “short-swing” profit recovery provisions of Section 16 of the Exchange Act and related rules with respect to their purchases and sales of our securities. As such, stockholders will be unable to bring derivative claims for disgorgement of profits for trades by significant stockholders under Section 16(b) of the Exchange Act unless the significant stockholders are also directors or officers or the Seller Related Parties.

Since Pubco Class A Stock will be our only class of stock registered under Section 12 of the Exchange Act and that class is non-voting, we will not be required to file proxy statements or information statements under Section 14 of the Exchange Act, unless a vote of Pubco Class A Stock is required by applicable law. Accordingly, legal causes of action and remedies under Section 14 of the Exchange Act for inadequate or misleading information in proxy statements may not be available to holders of Pubco Class A Stock. If we do not deliver any proxy statements, information statements, annual reports, and other information and reports to the holders of Pubco Class B Stock, then we will similarly not provide any of this information to holders of Pubco Class A Stock. Because we are not required to file proxy statements or information statements under Section 14 of the Exchange Act, any proxy statement, information statement or notice of our annual meeting may not include all information under Section 14 of the Exchange Act that a public company with voting securities registered under Section 12 of the Exchange Act would be required to provide to its stockholders. Most of that information, however, will be reported in other public filings. For example, disclosures required by Part III of Form 10-K as well as disclosures required by Nasdaq that are customarily included in a proxy statement will be included in our Form 10-K, rather than a proxy statement. But some information required in a proxy statement or information statement is not required in any other public filing. For example, we will not be required to comply with the proxy access rules under Section 14 of the Exchange Act. If we take any action in an extraordinary meeting of stockholders where the holders of Pubco Class A Stock are not

99

entitled to vote, we will not be required to provide the information required under Section 14 of the Exchange Act. Nor will we be required to file a preliminary proxy statement under Section 14 of the Exchange Act. Since that information is also not required in a Form 10-K, holders of Pubco Class A Stock may not receive the information required under Section 14 of the Exchange Act with respect to extraordinary meetings of stockholders. In addition, we will not be subject to the “say-on-pay” and “say-on-frequency” provisions of the Dodd–Frank Act. As a result, our stockholders will not have an opportunity to provide a non-binding vote on the compensation of our executive officers. Moreover, holders of Pubco Class A Stock will be unable to bring matters before our annual meeting of stockholders or nominate directors at such meeting, nor can they submit stockholder proposals under Rule 14a-8 of the Exchange Act. For more information regarding our reporting obligations, see “Additional Information.”

Risks Related to Taxation

Unrealized fair value gains on our AVAX holdings could cause us to become subject to the corporate alternative minimum tax under the Inflation Reduction Act of 2022.

The U.S. enacted the Inflation Reduction Act of 2022 (“IRA”) in August 2022. Unless an exemption applies, the IRA imposes a 15% corporate alternative minimum tax (“CAMT”) on a corporation with respect to an initial tax year and subsequent tax years, if the average annual adjusted financial statement income for any consecutive three-tax-year period preceding the initial tax year exceeds $1 billion. On September 12, 2024, the Department of Treasury and the IRS issued proposed regulations with respect to the application of CAMT.

Additionally, we are required to adopt ASU 2023-08, under which AVAX holdings must be measured at fair value in our statement of financial position, with gains and losses from changes in the fair value of our AVAX recognized in net income each reporting period. When determining whether we are subject to CAMT and when calculating any related tax liability for an applicable tax year, the proposed regulations provide that, among other adjustments, our adjusted financial statement income must include any unrealized gains or losses reported in the applicable tax year. On September 30, 2025, the IRS announced that it intends to revise the proposed regulations and provided interim guidance that, for purposes of determining whether CAMT applies, companies may exclude unrealized gains or losses with respect to certain assets such as Bitcoin assuming certain requirements are met. Taxpayers are generally allowed to rely on such interim guidance until such proposed regulations are issued.

If we do become subject to CAMT, it could result in a material tax obligation that we would need to satisfy in cash, which could materially affect our financial results, including our earnings and cash flow, and our financial condition.

Pubco’s independent registered public accounting firm’s report for the year ended December 31, 2025, contains an explanatory paragraph that expresses substantial doubt about its ability to continue as a “going concern.”

Pubco’s financial statements have been prepared under the assumption that it will continue as a going concern. Pubco’s independent auditor has issued a report on Pubco’s audited financial statement for the years ended December 31, 2025 that includes an explanatory paragraph expressing substantial doubt in Pubco’s ability to continue as a going concern for one year from the date of such report. Pubco’s ability to continue as a going concern after the consummation of the Business Combination, is dependent on Pubco’s ability to obtain additional equity or debt financing or to generate cash flow from operations. Pubco’s financial statements do not include any adjustments that might result from the outcome of this uncertainty. The substantial doubt regarding the potential ability of Pubco to continue as a going concern may adversely affect its ability to obtain such debt or equity financing on reasonable terms or at all, or to execute its business strategies. Additionally, if Pubco is unable to continue as a going concern, investors, including holders of Pubco Stock following the Closing of the Business Combination, may lose some or all of their investment.

(4) The Nasdaq Proposal — an ordinary resolution to approve, for the purposes of complying with the applicable provisions of Nasdaq Rule 5635, (i) the issuance of shares of Pubco Stock in connection with the Business Combination, (ii) the issuance of shares of Pubco Stock in connection with the Company Unit Subscription, (iii) the issuance of shares of Pubco Stock in connection with the Dragonfly Contribution, (iv) the issuance of shares of Pubco Stock in connection with the Foundation Transaction and (v) the reservation for issuance of shares of Pubco Stock that will, upon Closing, be reserved pursuant to the Incentive Plan, to the extent such issuances would require shareholder approval under Nasdaq Rule 5635.

(5) Director Election Proposal — an ordinary resolution to approve, two (2) directors to be elected to the MLAC Board to serve until MLAC’s third annual general meeting of shareholders or their earlier death, resignation or removal (including if they are replaced at the consummation of the Business Combination or if, based upon the tabulated vote at the time of the meeting, MLAC is not authorized to consummate the Business Combination). We refer to this proposal as the “Director Election Proposal,” which is described in more detail in the accompanying proxy statement/prospectus under the heading “The Director Election Proposal.”

(6) The Adjournment Proposal — an ordinary resolution to approve the adjournment of the Meeting to a later date or dates, if it is determined by MLAC that additional time is necessary or appropriate to complete the Business Combination or for any other reason. See the section entitled “The Adjournment Proposal.”

Recommendation of the MLAC Board

The MLAC Board has unanimously determined that the Business Combination Proposal is in the best interests of MLAC and the MLAC Shareholders; has unanimously approved the Business Combination Proposal; and unanimously recommends that shareholders vote “FOR” the Business Combination Proposal, “FOR” the Merger Proposal, “FOR” each of the Domestication and Organizational Documents Proposals, “FOR” the Nasdaq Proposal, “FOR” the Director Election Proposal and “FOR” the Adjournment Proposal, if presented.

Record Date; Issued and Outstanding Shares; MLAC Shareholders Entitled to Vote

MLAC Shareholders will be entitled to vote or direct votes to be cast at the Meeting if they owned MLAC Ordinary Shares at the close of business on           , 2026, which is the Record Date for the Meeting. MLAC Shareholders are entitled to one vote at the Meeting for each MLAC Ordinary Share held as of the Record Date. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the Meeting and vote, obtain a proxy from your broker, bank or nominee.

As of the close of business on the Record Date, there were 30,992,500 MLAC Ordinary Shares issued and outstanding, consisting of 23,805,000 MLAC Class A Ordinary Shares and 7,187,500 MLAC Class B Ordinary Shares. Of these shares, 23,000,000 were Public Shares.

Quorum and Vote of MLAC Shareholders

A quorum of MLAC Shareholders is necessary to hold a valid meeting. A quorum for the Meeting consists of the holders of one-third of the then issued and outstanding MLAC Ordinary Shares (whether in person or by proxy). As of the Record Date, MLAC Shareholders holding 10,330,834 MLAC Ordinary Shares would be required to achieve a quorum at the Meeting without the MLAC Ordinary Shares held by the Sponsor. In addition to the MLAC Ordinary Shares held by the Sponsor, which represent approximately 24.8% of the issued and outstanding MLAC Ordinary Shares and which will count towards this quorum, MLAC will need only MLAC Shareholders holding 2,648,334 MLAC Ordinary Shares, or 11.5%, of the 23,000,000 Public Shares represented in person or by proxy at the Meeting to have a valid quorum.

102

To pass, each of the Business Combination Proposal, the Nasdaq Proposal, the Director Election Proposal and the Adjournment Proposal requires an ordinary resolution of MLAC Shareholders, which requires the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). To pass, the Merger Proposal requires a special resolution of MLAC Shareholders, which requires the affirmative vote of at least two-thirds of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). MLAC Shareholders are also being asked to approve by way of ordinary resolutions, on a non-binding advisory basis, each of the Domestication and Organizational Documents Proposals. Although the MLAC Board is asking MLAC Shareholders to approve each of the Domestication and Organizational Documents Proposals on the non-binding advisory basis, regardless of the outcome of the non-binding advisory vote on each of the Domestication and Organizational Documents Proposals, the Amended and Restated Pubco Charter and Pubco’s Amended and Restated Bylaws will take effect upon the Closing if the MLAC Shareholder Approval Matters are approved.

Assuming a quorum is established, an MLAC Shareholder’s failure to vote by proxy or to vote at the Meeting will have no effect on the Proposals. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast and will have no effect on any of the Proposals.

The Sponsor has agreed to vote its 7,682,500 MLAC Ordinary Shares, representing 24.8% of the issued and outstanding MLAC Ordinary Shares, in favor of each of the Proposals. As a result, with respect to each Proposal that requires approval of MLAC Shareholders by an ordinary resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 7,813,751, or 34.0%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposals in order to have such Proposals approved. With respect to the Merger Proposal which requires approval of MLAC Shareholders by a special resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 12,979,167, or 56.4%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposal in order to have such Proposal approved.

Voting Your MLAC Ordinary Shares

Each MLAC Ordinary Share that you own in your name entitles you to one vote. Your proxy card shows the number of MLAC Ordinary Shares that you own. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the MLAC Ordinary Shares you beneficially own are properly counted.

Voting Your MLAC Ordinary Shares — Shareholders of Record

There are three ways to vote your MLAC Ordinary Shares at the Meeting:

You Can Vote By Signing and Returning the Enclosed Proxy Card. If you vote by proxy card, your “proxy,” whose name is listed on the proxy card, will vote your MLAC Ordinary Shares as you instruct on the proxy card. If you sign and return the proxy card but do not give instructions on how to vote your shares, your MLAC Ordinary Shares will be voted as recommended by the MLAC Board “FOR” the Business Combination Proposal, “FOR” the Merger Proposal, “FOR” each of the Domestication and Organizational Documents Proposals, “FOR” the Nasdaq Proposal, “FOR” the Director Election Proposal and “FOR” the Adjournment Proposal, if presented. Votes received after a matter has been voted upon at the Meeting will not be counted.

You Can Attend the Meeting virtually and Vote By Internet. MLAC Shareholders who have received a copy of the proxy card by mail may be able to vote over the Internet by visiting https://www.cstproxy.com/mountainlakeacquisition/2026 and entering the voter control number included on your proxy card. You may vote by Internet until the polls are closed on the date of the Meeting.

You Can Attend Meeting and Vote. If you attend the Meeting, you may submit your vote at the Meeting, in which case any proxy that you have given will be revoked and only the vote you cast at the Meeting will be counted.

103

Voting Your Shares — Beneficial Owners

If your MLAC Ordinary Shares are registered in the name of your broker, bank or other nominee, you are the “beneficial owner” of those MLAC Ordinary Shares and those MLAC Ordinary Shares are considered as held in “street name.” If you are a beneficial owner of MLAC Ordinary Shares registered in the name of your broker, bank or other nominee, you should have received a proxy card and voting instructions with these proxy materials from that organization rather than directly from MLAC. Simply complete and mail the proxy card to ensure that your vote is counted. You may be eligible to direct the vote of your MLAC Ordinary Shares electronically over the Internet or by telephone. A large number of banks and brokerage firms offer Internet and telephone voting. If your bank or brokerage firm does not offer Internet or telephone voting information, please complete and return your proxy card in the self-addressed, postage-paid envelope provided. To vote yourself at the Meeting, you must first obtain a valid legal proxy from your broker, bank or other nominee who are the holder of record and then register in advance to attend the Meeting. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a legal proxy form.

After obtaining a valid legal proxy from your broker, bank or other nominee, to then register to attend the Meeting, you must submit proof of your legal proxy reflecting the number of your MLAC Ordinary Shares along with your name and email address to CST. Requests for registration should be directed via e-mail to proxy@continentalstock.com or via telephone to (917) 262-2373. Written requests can be mailed to:

Share Ownership of and Voting by MLAC Sponsor, Directors and Officers

The Sponsor has agreed to vote its 7,682,500 MLAC Ordinary Shares, representing 24.8% of the issued and outstanding MLAC Ordinary Shares, in favor of each of the Proposals. As a result, with respect to each Proposal that require approval of MLAC Shareholders by an ordinary resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 7,813,751, or 34.0%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposals in order to have such Proposals approved. With respect to the Merger Proposal which requires approval of MLAC Shareholders by a special resolution, in addition to the Sponsor’s MLAC Ordinary Shares, MLAC would need only 12,979,167, or 56.4%, of the 23,000,000 Public Shares (assuming all issued and outstanding MLAC Ordinary Shares are voted at the Meeting), and would not need any of the 23,000,000 Public Shares (assuming a minimum number of MLAC Ordinary Shares to achieve a quorum are voted at the Meeting), to be voted in favor of such Proposal in order to have such Proposal approved.

Who Can Answer Your Questions About Voting Your Shares

If you are an MLAC Shareholder and have any questions about how to vote or direct a vote in respect of your MLAC Ordinary Shares, you may call MLAC’s proxy solicitor, Sodali & Co, MLAC’s proxy solicitor, at (203) 658-9400 (banks and brokers) or email at MLAC.info@investor.sodali.com.

Redemption Rights

Pursuant to the MLAC Memorandum and Articles, any holders of Public Shares may demand that such Public Shares be redeemed in exchange for a pro rata share of the aggregate amount on deposit in the Trust Account (less taxes payable), calculated as of two (2) business days prior to the Closing. If a demand is properly made and the Business Combination is consummated, these shares, immediately prior to the Business Combination, will cease to be outstanding and will represent only the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account which holds the proceeds of the MLAC IPO (calculated as of two (2) business days prior to the Closing, including interest earned on the funds held in the Trust Account and not previously released to MLAC to pay its taxes). For illustrative purposes, based on funds in the Trust Account of approximately $241.2 million as of December 31, 2025 and $244.2 million as of May 4, 2026, the estimated per share redemption prices would have been approximately $10.49 per share and $10.62 per share, respectively (including interest earned on the funds held in the Trust Account but less taxes payable).

In order to exercise your redemption rights, you must:

• prior to 5:00 p.m. Eastern Time on             , 2026 (two (2) business days before the Meeting), tender your Public Shares physically or electronically and submit a request in writing that MLAC redeem your Public Shares for cash to CST, MLAC’s transfer agent, at the following address:

Continental Stock Transfer & Trust Company
One State Street Plaza, 30^th Floor
New York, New York 10004
Attn: SPAC Redemption Team
Email: spacredemptions@continentalstock.com

• In your request to CST for redemption, you must also affirmatively certify if you “ARE” or “ARE NOT” acting in concert or as a “group” (as defined in Section 13d-3 of the Exchange Act) with any other Public Shareholder; and

• deliver your Public Shares either physically or electronically through DTC to CST at least two (2) business days before the Meeting. Public Shareholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from CST and time to effect delivery. It is MLAC’s understanding that Public Shareholders should generally allot at least two weeks to obtain physical certificates from Continental Stock Transfer

105

and Trust Company. However, MLAC does not have any control over this process and it may take longer than two weeks. Public Shareholders who hold their Public Shares in street name will have to coordinate with their bank, broker or other nominee to have the shares certificated or delivered electronically. If you do not submit a written request and deliver your Public Shares as described above, your Public Shares will not be redeemed.

A Public Shareholder may not withdraw a redemption request once submitted to MLAC unless the MLAC Board determines (in their sole discretion) to permit the withdrawal of such redemption request (which they may do in whole or in part). Subject to the forgoing, if you delivered your Public Shares for redemption to CST and decide within the required timeframe not to exercise your redemption rights, you may request that CST return your Public Shares (physically or electronically). You may make such request by contacting CST at the phone number or address listed above.

Prior to exercising redemption rights, Public Shareholders should verify the market price of MLAC Class A Ordinary Shares, as they may receive greater proceeds from the sale of their Public Shares in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. There can be no assurances that you will be able to sell your Public Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in MLAC Class A Ordinary Shares when you wish to sell your Public Shares.

If you exercise your redemption rights, your Public Shares will cease to be outstanding immediately prior to the consummation of the Business Combination and will only represent the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account. You will no longer own those shares and will have no right to participate in, or have any interest in, the future growth of Pubco, if any. You will be entitled to receive cash for these shares only if you properly and timely demand redemption.

Notwithstanding the foregoing, the MLAC Memorandum and Articles provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than 15% of the Public Shares in the aggregate, without the prior consent of MLAC.

In connection with the MLAC IPO, the Sponsor and its Affiliates agreed to waive any redemption rights with respect to any MLAC Ordinary Shares held by them in connection with the completion of the Business Combination. Such waivers are standard in transactions of this type and the Sponsor and its Affiliates did not receive separate consideration for the waiver.

Appraisal Rights

MLAC Shareholders do not have appraisal rights in connection with the Business Combination under the DGCL or the Cayman Act.

In addition, Public Shareholders are still entitled to exercise the rights of redemption as detailed in this proxy statement/prospectus and the redemption proceeds payable to Public Shareholders who exercise such redemption rights will represent the fair value of those shares. For a discussion about the Public Shareholders’ redemption rights, please see “Extraordinary General Meeting of MLAC Shareholders — Redemption Rights.”

Proxy Solicitation Costs

MLAC is soliciting proxies on behalf of the MLAC Board. This solicitation is being made by mail but also may be made by telephone, on the Internet or in person. MLAC and its directors, officers and employees may also solicit proxies in person, by telephone or by other electronic means. MLAC will file with the SEC all scripts and other electronic communications as proxy soliciting materials. MLAC will bear the cost of the solicitation.

MLAC has hired Sodali & Co. to assist in the proxy solicitation process. MLAC will pay Sodali & Co. a fee of $22,500, plus disbursements of its expenses in connection with services relating to the Meeting.

MLAC will ask banks, brokers and other institutions, nominees and fiduciaries to forward the proxy materials to their principals and to obtain their authority to execute proxies and voting instructions. MLAC will reimburse them for their reasonable expenses.

THE BUSINESS COMBINATION PROPOSAL

General

MLAC Shareholders are being asked to approve the Business Combination Agreement and the Business Combination. MLAC Shareholders should read carefully this proxy statement/prospectus in its entirety for more detailed information concerning the Business Combination Agreement, a copy of which is attached hereto as Annex A. Please see the section entitled “The Business Combination Proposal — The Business Combination Agreement” and “Summary of the Proxy Statement/Prospectus — Transactions — Related Agreements” below for additional information and a summary of certain terms of the Business Combination Agreement. You are urged to read carefully the Business Combination Agreement in its entirety before voting on this Proposal.

MLAC may consummate (i) the Business Combination only if the Business Combination Proposal is approved by an ordinary resolution, being a resolution passed at the Meeting by the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of quorum) and (ii) the Merger Proposal is approved by a special resolution, being a resolution passed at the Meeting by the affirmative vote of at least two-thirds of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum).

If any of those Proposals are not approved by MLAC Shareholders, the Business Combination will not be consummated. The Merger Proposal is conditional upon the approval of the Business Combination Proposal. The Domestication and Organizational Documents Proposals and the Nasdaq Proposal are conditional upon the approval of the Business Combination Proposal and the Merger Proposal. The Director Election Proposal and the Adjournment Proposal are not conditioned on the approval of any other Proposal.

After completion of the transactions contemplated by the Business Combination Agreement: the corporate headquarters and principal executive offices of Pubco will be located at c/o Studio, 11 West 42^nd Street, 2^nd Floor, New York, NY 10036 and if Pubco’s application for listing are approved, shares of Pubco Stock are expected to be traded on Nasdaq under the symbol “AVAT.”

Background of the Business Combination

MLAC is a blank check company incorporated in the Cayman Islands on June 14, 2024 to effect a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. On December 16, 2024, MLAC consummated the MLAC IPO and began its search for an acquisition target. Prior to the consummation of the MLAC IPO, neither MLAC, nor anyone on its behalf, engaged in any substantive discussions, directly or indirectly, with any business combination target.

108

Upon the consummation of the MLAC IPO, MLAC began its search for prospective businesses to acquire in its initial business combination. MLAC conducted an extensive search for a potential business combination transaction drawing upon, among other things, the network and investment and operating experience of the MLAC’s management team and the MLAC Board. During its search process, MLAC entered into 16 non-disclosure agreements (including the NDA (as defined below)) with prospective target businesses and prepared four letters of intent (including the LOI (as defined below)).

MLAC reviewed the potential acquisition opportunities based on criteria that were the same or similar to the criteria that the MLAC Board used in evaluating the potential Business Combination with AVAT (as discussed below), which included, among other criteria, the potential to hold a leading position in an industry sector, the readiness and willingness of potential target companies to become public, the experience of the potential target companies’ management teams and the potential for strong and sustainable free cash flow.

The terms of the Business Combination were the result of arm’s-length negotiations between representatives of MLAC, the Company, Pubco, Seller, Robert Hadick and Gerald Bartholomew Smith (Messrs. Hadick and Smith, together with the Company, Pubco and Seller, the “AVAT Parties”), as further described below. Barclays Capital Inc. (“Barclays”) and PJT Partners LP (“PJT” and, together with Barclays, the “Investment Banks”) acted as placement agents with respect to the Company Unit Subscription and capital markets advisors with respect to the Business Combination. PJT also acted as exclusive financial advisor to AVAT in connection with the Business Combination.

The following chronology summarizes the key meetings and events that led to the signing of the Business Combination Agreement. This chronology does not purport to catalogue every correspondence among representatives of MLAC, the AVAT Parties and the Investment Banks.

Description of Negotiation Process with Candidates other than Pubco/the Company.

Below is a summary of targets other than the Company that were considered and with which MLAC Management had significant discussions, and the reasons why MLAC did not proceed with these candidates.

• Target A: A digital asset investment company located outside the United States reached out via one of its advisors on January 11, 2025, to discuss the possibility of engaging in a business combination. On January 22, 2025 Target A’s CEO shared a presentation with MLAC Management. Over the next few months Target A’s CEO, Paul Grinberg and Douglas Horlick met virtually and in person, to discuss the terms of a potential business combination. MLAC Management sent a proposed letter of intent to Target A’s CEO in early June 2025, which was not accepted by Target A.

• Target B: An autonomous vehicle company that MLAC was introduced to by Target B’s banker in April 2025. Beginning in May 2025, MLAC visited Target B’s headquarters, had several discussions with Target B’s management team and shared several drafts of a letter of intent with Target B. MLAC decided not to proceed with the transaction in late July 2025 primarily because the parties were unable to reach agreement on a minimum cash condition for closing.

• Target C: A computer-related company that MLAC was introduced to by Target C’s banker in late July 2025. After several virtual meetings, MLAC decided in late August 2025 to pause negotiations with Target C in order to focus on the AVAT opportunity.

Description of Negotiations between MLAC and Pubco/the Company.

On August 7, 2025, the Seller engaged Skadden, Arps, Slate, Meagher & Flom (UK) LLP (“Skadden”) to serve as counsel for the Business Combination. The Seller did not materially consider any transactions other than the Business Combination.

On August 8, 2025, the ticker “AVAT” was reserved across exchanges with an expiration date of August 8, 2027.

On August 14, 2025, at the direction of AVAT, PJT circulated kick-off discussion materials including an outline of the investor presentation and targeting plan for the Company Unit Subscription.

On August 14, 2025, at the direction of AVAT, PJT hosted a Project Chamber Kick-off call including PJT, Barclays, the Seller, Gerald Bartholomew Smith and Skadden. Following this first introductory call this group held bi-weekly status calls every Tuesday and Thursday to discuss next steps in the transaction process.

109

On August 18, 2025, the Seller and Avalanche BVI entered into a non-binding letter of intent (the “Foundation LoI”) setting out certain key terms for the sale of AVAX tokens by Avalanche BVI to a digital asset treasury vehicle. The key terms included: (i) a commitment by Avalanche BVI to contribute at least $200 million of AVAX tokens to the Company, priced at a 60% discount; (ii) a contribution by the Seller of up to 1,960,040 AVAX tokens from its affiliated funds; (iii) the final structure of the digital asset treasury vehicle to be determined during definitive documentation; (iv) Avalanche BVI shall be entitled to appoint a representative as a member of the board of directors of such to-be-formed digital asset treasury vehicle; (v) Avalanche BVI may elect to receive an allocation of shares in the to-be-formed digital asset treasury vehicle or cash proceeds or a combination of both; and (vi) exclusivity for 18 months during which Avalanche BVI will not sell AVAX tokens to any other digital asset treasury vehicle listed on a U.S. national stock exchange with a business model primarily dependent on owning AVAX, except as agreed by the parties. The Foundation LoI is non-binding except for provisions regarding confidentiality, exclusivity, and certain miscellaneous terms.

On August 18, 2025, at the direction of AVAT, PJT scheduled a series of meetings with Skadden and Barclays to discuss Company Unit Subscription and SPAC targeting matters.

On August 19, 2025, a representative of Barclays, who was aware of MLAC Management’s experience in the digital asset space, approached Douglas Horlick, President of MLAC, with the AVAT opportunity.

On August 20, 2025, MLAC Management received a non-disclosure agreement (“NDA”) from the AVAT Parties.

On August 20, 2025, Avalanche Treasury Company LLC was formed as a Delaware limited liability company in order to pursue the Business Combination.

On August 22, 2025, after some minor negotiated changes MLAC Management and the AVAT Parties executed the NDA.

On August 27, 2025, a meeting between Barclays and MLAC Management, which included Paul Grinberg and Mr. Horlick, was held to discuss the AVAT opportunity and to determine if this would be of interest to MLAC. Subsequently, representatives of Barclays introduced representatives of the AVAT Parties by e-mail to MLAC Management. This led to a meeting on August 28, 2025 by and among representatives of Barclays, MLAC Management, MLAC director Jamie Vieser, and the AVAT Parties, where Mr. Hadick and Mr. Smith provided a detailed overview of AVAT.

On August 28, 2025, Mr. Hadick shared a draft of the Contribution Agreement with the AVAT Parties reflecting the terms of the Foundation LoI, therefore governing the contribution of AVAX tokens to the Company by both Avalanche BVI and the Seller Related Parties.

On August 29, 2025, MLAC Management, Mr. Hadick and Mr. Smith had a follow-up meeting where MLAC Management asked detailed questions about the proposed business.

On August 31, 2025, MLAC Management, Mr. Hadick and Mr. Smith held a meeting where they discussed the terms of a potential deal. Those discussions and negotiations continued over the course of multiple meetings held on September 1, 2025.

On September 1, 2025, MLAC Management agreed via email with the AVAT Parties on key points of a draft letter of intent (the “LOI”) regarding the potential Business Combination. The key terms, proposed by the AVAT Parties and accepted by MLAC Management, included: (i) a contribution by Seller of up to 1,960,040 AVAX tokens in exchange for 2,000,000 Pubco Class A Stock and 2,000,000 Pubco Class B Stock, each subject to certain price-based earnouts; (ii) a contribution by the Foundation of at least $200 million of AVAX tokens, priced at a 60% discount, (iii) a dual-class structure for Pubco consisting of voting and non-voting classes of stock; (iv) a PIPE commitment of at least $300 million on or prior to the execution of definitive agreements; (iv) the forfeiture by Sponsor of up to 7,187,500 founder shares (excluding 1,200,000 founder shares) and all of its 495,000 private placement units; and (vi) reciprocal earnout requirements for the securities to be held by each of Seller and the MLAC Sponsor. Points of heavier negotiation included the price-based thresholds for the reciprocal earnout milestones, the number of Founder Shares subject to forfeiture and the scope and structure of the voting rights to be granted to Seller and its designees under a dual- class regime. The LOI provided for an initial 30-day exclusivity period, subject to automatic 30-day renewal periods unless earlier terminated by any party.

On September 1 and 2, 2025, MLAC Management discussed with individual MLAC Board Members the proposed Business Combination. The MLAC Board was unanimously supportive of MLAC entering into the LOI.

110

On September 3, 2025, upon further negotiation, MLAC and AVAT executed the LOI. The final terms reflected what was previous agreed upon.

On September 4, 2025, MLAC began its due diligence of the AVAT Parties.

On September 4, 2025, the Foundation shared their comments to the Contribution Agreement, including the request to have two separate agreements governing the transfer of AVAX tokens to the Company by the Foundation and the Seller Related Parties rather than one, as originally envisaged in the Foundation LoI and in the first version of the Contribution Agreement dated as of August 28, 2025. In particular, the proposed revised structure envisaged: (i) a Contribution Agreement between Dragonfly and the Company, and (ii) a Token Sale Agreement between the Foundation and the Company. Simultaneously, the Foundation shared a first draft of the Token Sale Agreement, based on a standard form agreement normally used by the Foundation for the sale of AVAX tokens and incorporating the provisions regarding pricing, consideration, and restrictions applicable to the transfer of AVAX tokens by the Foundation to the Company, as previously included in the Contribution Agreement.

On September 5, 2025, Sidley Austin LLP (“Sidley”), counsel to the Foundation with respect to the Contribution Agreement and the Token Sale Agreement had a call with Mr. Hadick, Skadden and the Seller to discuss the mechanics of the Contribution Agreement and the Token Sale Agreement and how the agreements are intended to work together as well as other specific provisions of the Token Sale Agreement (e.g., the indemnity provisions, a proposed rescission rights for the Foundation, the date for the calculation of the VWAP, and representation and warranties of the Company).

On September 5, 2025, MLAC Management and representatives of the AVAT Parties had a meeting to plan for the process for the proposed Business Combination, which included an introduction to potential auditors and accountants for the Company.

Between September 5, 2025 and October 1, 2025, MLAC Management engaged in discussions with BTIG, MLAC’s IPO underwriter, with respect to its engagement as a financial and capital markets advisors to MLAC in the Business Combination. In connection with such engagement, BTIG agreed to forfeit its 310,000 Private Placement Units and all deferred underwriting fees payable upon consummation of the Business Combination in excess of $1,000,000.

On September 8, 2025, MLAC engaged Ellenoff Grossman & Schole LLP (“EGS”), to serve as its counsel with respect to the Business Combination.

On September 8, 2025, Skadden shared with Sidley and the Foundation updated drafts of the Contribution Agreement and the Token Sale Agreement, reflecting the new structure proposed by the Foundation to have two different agreements governing the transfer of AVAX Tokens to the Company and setting out among other things the form of payment (split between cash and shares in Pubco) and conditions and timing of such contribution.

On October 2, 2025, representatives from Dragonfly discussed with Skadden (via email and a conference call) amending the Business Combination Agreement in order to, inter alia:

(i)add the DVs and Astral as original parties to the Business Combination Agreement;

(ii)clarify that the Company Units held by the DVs (as Sponsored Controlled Vehicles as defined in the Contribution Agreement) were to be treated as the Company Units held by Seller such that, as a result of the Company Merger, the DVs would receive one (1) Pubco Class A Stock and one (1) Pubco Class B Stock for each Company Unit held by the DVs; and

(iii)provide that the Additional Merger Consideration Shares to be issued at Closing (a) be issued to Astral rather than to Seller (as provided in the original Business Combination Agreement), and (b) consist of 4,000,000 shares of Pubco Class A Stock only, with no Pubco Class B Stock to be allotted as Additional Consideration (since Astral does not qualify as one of the Seller Related Parties).

Representatives from Dragonfly requested for the DVs to be added as parties to the Business Combination Agreement through the First Amendment because the DVs are the entities that actually contributed the AVAX tokens (as opposed to the Seller). Astral was added as a party to the Business Combination because the Pubco Stok they will receive is being issued in consideration for advisory and strategic services provided by Astral’s limited partners in connection with the structuring and execution of the Business Combination and the establishment of Pubco. Such services include, but are not limited to:

(i)Executive Recruitment: Astral’s limited partners assisted in identifying, evaluating, and recruiting the Chief Executive Officer of Pubco; and

(ii)Tax and Corporate Structuring Advisory: Astral’s limited partners provided strategic advice regarding aspects of the tax and corporate structuring of the Business Combination and post-Closing operations of Pubco.

On January 15, 2026, representatives from Dragonfly discussed with Skadden (via email) amending the BCA to postpone, in order to accommodate Astral from an operational and administrative perspective, the issuance to Astral of the 2,000,000 Astral Post-Closing Shares for a certain period of time, so that such issuance would occur after Closing, rather than on the Company Merger Effective Date.

Between January 26 and 28, 2026, Skadden and representatives of Dragonfly had additional discussions on the proposed postponement of the issuance to Astral of the 2,000,000 Astral Post-Closing Shares and the relevant duration. Representatives from Dragonfly confirmed that they expected a postponement of one month to be sufficient to allow Astral to prepare, from operational and administrative perspective, to receive the Astral Post-Closing Shares and asked Skadden to draft the Second Amendment.

On February 6, 2026, Skadden shared with Dragonfly and AVAT the first draft of the Second Amendment, which was signed off by the Dragonfly and AVAT teams on February 16, 2026.

On February 16, 2026, Skadden shared with EGS the first draft of the Second Amendment.

On March 17, 2026, the parties executed the Second Amendment, pursuant to which the parties thereto agreed to postpone the issuance by Pubco to Astral of the 2,000,000 Astral Post-Closing Shares so that such issuance will occur on the thirtieth (30th) calendar day following the Closing Date, rather than on the Company Merger Effective Date. On the same day, MLAC filed with the SEC the Form 8-K that included a copy of the executed Second Amendment.

The parties have continued and expect to continue regular discussions and weekly calls regarding the timing to consummate the Business Combination and necessary preparation in connection therewith. Additionally, since the execution of the Business Combination Agreement, MLAC Management has actively communicated with individual MLAC Board members regarding the status of the Business Combination, as well as market conditions generally. The AVAX market has been characterized by significant volatility since its mainnet launch in September 2020, and will likely continue to experience significant volatility until the Closing of the Business Combination. Prior to approving the Business Combination, the MLAC Board considered AVAX’s pricing volatility in its evaluation of the proposed Transactions, as well as other uncertainties, risks and other potentially negative factors described in ”—MLAC Board’s Reasons for Approval of the Business Combination,” such as the considerable regulatory and macroeconomic uncertainty faced by AVAT and other players in the digital asset industry. The MLAC Board nonetheless believed, and continues to believe, that the Business Combination presents an attractive opportunity to generate value for MLAC shareholders. The Transaction’s discounted mNAV structure is designed to generate value to shareholders immediately upon Closing. Moreover, the MLAC Board believes AVAT’s relationship with the Foundation can create opportunities for long-term value that will outweigh future short-term swings in AVAX price. Finally, MLAC Management’s interactions with Pubco leadership since October 2025 have reinforced MLAC Management’s confidence in their ability to lead and grow Pubco’s business after Closing. Therefore, the MLAC Board does not believe that any recent change in the price of AVAX changes its assessment of the Transactions.

MLAC Board’s Reasons for Approval of the Business Combination

The MLAC Board considered a variety of factors in connection with its evaluation of the Business Combination. In light of the complexity of those factors, the MLAC Board, as a whole, did not consider it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it took into account in reaching its decision. Individual members of the MLAC

115

Board may have given different weight to different factors. Certain information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under “Cautionary Note Regarding Forward-Looking Statements.”

Before reaching its decision, the MLAC Board reviewed the information provided to it by its management, representatives of the Sponsor and MLAC’s legal and financial advisors. In addition, before determining that the Business Combination was in the best interests of MLAC and its shareholders, the MLAC Board reviewed various industry data, including a review of recent performance of public companies with the digital asset treasury strategies, such as MicroStrategy, as well as industry insights provided by the Investment Banks, which were included in the investor presentation for the Company Unit Subscription.

The MLAC Board determined that pursuing a potential business combination with Pubco and the Company would be an attractive opportunity for MLAC and the MLAC Shareholders, which determination was based on a number of factors including, but not limited to, the following:

• Exclusive partnership with the Foundation, which includes compelling access to AVAX. AVAT has an 18-month exclusive agreement with the Foundation on AVAX sales to any DAT company and, through its relationship with the Foundation, access to opportunities with partners, investors, builders, and service providers across the Avalanche ecosystem.

• Differences between AVAT and other DATs in the marketplace. AVAT seeks to employ an active (instead of passive) DAT strategy, combining a targeted yield strategy with ecosystem development that is designed to provide shareholders with more holistic exposure to the growth of the Avalanche ecosystem.

• Structural trends driving Avalanche utilization, including growth in stablecoin and digital money markets; as well as the tokenization of equities, private credit and other real world assets.

• Avalanche’s technological strengths, including processing speed and ease of customization.

• Attractive economics, including a discounted mNAV of approximately 0.77x at the execution of the Business Combination Agreement, assuming no redemptions from MLAC Shareholders.

• Strategic leadership on board and Advisory Board, including Advisory Board members Ava Labs founder Emin Gün Sirer, managing partner of Dragonfly Haseeb Qureshi, Blockworks Inc. Chief Executive Officer Jason Yanowitz and Aave Labs Chief Executive Officer Stani Kulechov.

• Strong management team with institutional connectivity, Avalanche protocol expertise, and over 20 years of experience across digital assets, proprietary trading, asset management, market making and institutional capital markets.

• Avalanche real world use cases across finance, payments, corporate/enterprise, government, gaming, sports and entertainment, which signifies the potential for significant market acceptance and adoption. Examples include the use of Avalanche technology in JP Morgan’s Kinexys, the California DMV’s registration of 42 million vehicle titles, Apollo’s launch of tokenized portfolios, funds and private credit, and FIFA’s launch of its own blockchain for digital collectibles and enhanced fan engagement.

In connection with its approval of the Business Combination Agreement, the MLAC Board considered the enterprise valuations, after factoring in the Company Unit Subscription, the Foundation’s token sale, and the implied value of AVAX holdings (or mNAV). Additionally, the MLAC Board considered potential valuation multiples of other digital asset tokens such as those supported by the blockchain platforms Ethereum, Stellar, Cardano, and Solana. The MLAC Board believed that the transaction structure for the Business Combination, which features a discounted mNAV, could deliver significant returns on investment to MLAC Shareholders. The MLAC Board also considered the Company’s unique relationship with the Foundation and its potential to provide strategic exposure to the evolving Avalanche ecosystem, which the MLAC Board believed presented a compelling opportunity for value creation for MLAC Shareholders.

116

In approving the Business Combination, the MLAC Board considered the potential benefits of, but ultimately determined not to obtain, a fairness opinion. The MLAC Board and MLAC’s management have extensive experience in the fintech industry, operational management and investment and financial analysis, including as part of the team’s prior involvement in the proposed acquisition of W3BCLOUD Holdings Inc, a cryptocurrency data center, by Social Leverage Acquisition Corp. I. Furthermore, members of the MLAC Board have made professional investments in the digital asset space. As such, the members of the MLAC Board and management team believe that they are qualified to conduct and analyze the due diligence required to identify a business combination partner. The independent directors of the MLAC Board did not retain an unaffiliated representative to act solely on behalf of the unaffiliated MLAC Shareholders to negotiate the terms of the Business Combination and/or prepare a report concerning the approval of the Business Combination.

In the course of its deliberations, in addition to the various other risks associated with the business of Pubco, as described in the section entitled “Risk Factors” appearing elsewhere in this proxy statement/prospectus, the MLAC Board also considered a variety of uncertainties, risks and other potentially negative factors relevant to the Business Combination, including the following:

• AVAX and the Volatility of the Price of AVAX. The market prices of AVAX Tokens and other digital assets may fluctuate significantly, potentially due to broader cryptocurrency market movements, regulatory developments, technological changes or general economic conditions. These fluctuations could materially affect the value of Pubco’s digital assets, its mNAV, and overall financial performance.

• Macroeconomic Risks Generally. Macroeconomic uncertainty, including the potential impact of the tariffs to be instituted by the United States government, and the effects they could have on the price of AVAX and Pubco’s potential financial performance.

• Regulatory Risks with respect to AVAX. Cryptocurrency-related regulations are evolving, and future developments regarding the treatment of crypto assets for U.S. and foreign tax purposes could adversely impact Pubco’s business. AVAX and other digital assets are novel assets, and are subject to significant legal, commercial, regulatory and technical uncertainty.

• Competition in Pubco’s Industry. Many publicly listed digital asset treasury vehicles currently trade at a premium to mNAV, which has attracted and may continue to attract other companies to pursue similar digital asset treasury strategies. This increased number of companies could make it more difficult or expensive for Pubco to, among other things, pursue its strategy of raising funds through public offerings of securities to purchase more AVAX for its corporate treasury.

• Risks in Pubco’s Business Plan, which Business Plan May Not be Achieved. Pubco does not have significant operations and will not have significant operations prior to Closing. Pubco may not be successful in building its AVAX holdings or in building the ancillary AVAX related services it intends to launch in tandem with the accumulation and management of its AVAX holdings. Pubco may encounter unforeseen expenses, difficulties, complications, delays and other unknown events that may cause its costs to exceed its expectations.

• Management Team of Pubco and Public Company Readiness. Gerald Bartholomew Smith, Laine Mihalchick Moljo and Sean Ostrower, who are expected to lead Pubco management after Closing, have limited experience managing an operating a public company. There is a risk that Pubco will not be able to hire the necessary personnel to timely and accurately prepare financial statements and reports to be publicly filed with the SEC, or that Pubco’s compliance infrastructure may not be able to successfully manage the increased compliance risks and internal controls requirements to which it will be subject as a public company.

• Valuation. The Company has no operating history and the volatile nature of the price of AVAX makes it difficult to evaluate Pubco’s future prospects. The Company’s lack of operating history also makes it difficult to accurately forecast its future results of operations, which are subject to numerous uncertainties as further described herein. In addition, MLAC did not obtain a fairness opinion (or any similar report or appraisal) in connection with the Business Combination. As a result, there is a risk that the MLAC Board may not have properly valued the Company’s business.

• Listing Risk. The challenges associated with preparing Pubco for requisite listing requirements to which it will be subject as a publicly traded company on a national stock exchange, and the potential inability of Pubco to obtain an initial listing and maintain the listing of Pubco Class A Stock on Nasdaq or any other securities exchange following the Closing.

117

• MLAC Shareholders Holding a Minority Position in Pubco. MLAC Shareholders will hold a minority ownership position in Pubco following completion of the Business Combination, with existing Public Shareholders owning approximately 40.5% of the issued and outstanding shares of Pubco Class A Stock after Closing, assuming no redemptions.

• Control of Pubco by the Seller. Pubco will have two classes of common stock after Closing, with Pubco Class A Stock having no voting rights (except as required by applicable law) until all shares of Pubco Class B Stock are cancelled, and Pubco Class B Stock having voting rights. At Closing, MLAC Shareholders will receive shares of Pubco Class A Stock and only the Seller will own shares of Pubco Class B Stock. As a result, Pubco will be a controlled company under Nasdaq listing standards after Closing, with all decisions of Pubco being controlled by the Seller. Accordingly, Public Shareholders will not participate in the governance of Pubco after Closing. For additional information, see the section of this proxy statement/prospectus entitled “Description of Pubco Securities.”

• Litigation. The possibility of litigation or MLAC shareholder actions challenging the Transactions or injunction against any of the actions required to be taken in order to consummate the Business Combination.

• Fees and Expenses. The fees and expenses associated with completing the Business Combination, including those payable to the Investment Banks and BTIG.

• Redemptions. The risk that a significant number of Public Shareholders may exercise their redemption rights, thereby depleting the amount of cash available in the Trust Account to fund Pubco’s business after the Business Combination, not only making it more difficult for Pubco to meet initial listing requirements, but also reducing the liquidity of the trading market for Pubco Class A Stock upon Closing.

In addition to considering the factors described above, the MLAC Board also considered that:

• Interests of Certain Persons. The Sponsor, its affiliates and certain executive officers and directors of MLAC, as individuals, may have interests in the Business Combination that are in addition to, and that may be different from (and may conflict with), the interests of MLAC Shareholders. The possibility that the MLAC Board may have been influenced by conflicts between what may be in MLAC’s best interests and what may be best for a director’s personal interests, including the possibility that if the Business Combination is not consummated, and MLAC is forced to liquidate because it is unable to consummate another business combination within the timeframe permitted by its Memorandum and Articles of Association, the Class B Ordinary Shares and Private Placement Units owned by the Sponsor would be worthless. For more information, see section entitled “The Business Combination Proposal — Interests of the Sponsor and MLAC’s Directors and Executive Officers in the Business Combination.”

• Differing Returns. The Sponsor paid $25,000, or approximately $0.005 per share, for the MLAC Founder Shares (of which it currently holds 7,187,500, 4,387,500 of which the Sponsor has agreed to surrender, immediately prior to, and subject to the consummation of, the MLAC Merger). Such shares (after accounting for the share surrender), are valued at approximately $28,924,000, based on the closing price of MLAC Class A Ordinary Shares of $10.30 on September 30, 2025, the business day before the MLAC Board approved the Business Combination. Such shares will be worthless if a business combination is not consummated. The Sponsor and Affiliates can earn a positive rate of return on their investment even if Public Shareholders experience a negative return following the consummation of the Business Combination.

After considering the foregoing, the MLAC Board concluded, in its business judgment, that the potential benefits to MLAC and the MLAC Shareholders relating to the Business Combination outweighed the potentially negative factors and risks relating to the Business Combination.

Satisfaction of 80% Test

It is a requirement under the MLAC Memorandum and Articles and Nasdaq listing requirements that the business or assets acquired in MLAC’s initial business combination have an aggregate fair market value equal to at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest income earned on the Trust Account) at the time of the execution of a definitive agreement for its initial business combination.

118

As of October 1, 2025, the date of the execution of the Business Combination Agreement, the balance of the funds in the Trust Account was approximately $241.2 million, and 80% of the assets thereof (excluding the deferred underwriting commissions and taxes payable on the interest income earned on the Trust Account) represents approximately $191.76 million. In reaching its conclusion that the Business Combination meets the 80% asset test, the MLAC Board looked at the expected value of an aggregate of approximately $460 million of digital treasury assets, comprised of (i) the 1,960,040 AVAX tokens to be contributed by the Seller in the Business Combination, and (ii) approximately $216 million to be invested by the Company Unit Investors. In determining whether the value described above represents the fair market value of the Business Combination, the MLAC Board considered all of the factors described above and the fact that the valuation of the AVAX assets is based on an independently established trading price and was the result of an arm’s length negotiation among MLAC, the Company, Pubco and the Seller. As a result, the MLAC Board concluded that the fair market value of the business or assets acquired was in excess of 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest income earned on the Trust Account). As a result, the MLAC Board concluded that the fair market value of the business acquired was in excess of 80% of the assets held in the Trust Account.

Interests of the Sponsor and its Affiliates in the Business Combination

When Public Shareholders consider the recommendation of the MLAC Board in favor of approval of the Business Combination and other Proposals, Public Shareholders should keep in mind that the Sponsor and its Affiliates have interests in the Proposals that are different from or in addition to (and which may conflict with), the interests of a Public Shareholder as an MLAC Shareholder. These interests include, among other things:

• the Sponsor paid $25,000 for the 7,187,500 MLAC Class B Ordinary Shares. Of these amounts, contemporaneously with the consummation of the Business Combination, the Sponsor shall submit for cancellation 4,387,500 MLAC Class B Ordinary Shares, and as a result, the Sponsor will retain the Retained Sponsor Shares. If the Business Combination or another MLAC initial business combination is not consummated by June 16, 2026 (or such other date as approved by the MLAC Shareholders), MLAC will cease all operations except for the purpose of winding up. In such event, the 2,800,000 Retained Sponsor Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be worthless because the holders thereof entered into an agreement waiving entitlement to participate in any redemption or liquidating distributions with respect to such shares. Neither the Sponsor nor any other person received any compensation in exchange for this agreement to waive redemption and liquidation rights. Pursuant to the terms of the Insider Letter and the Sponsor Lock-Up Agreement, the Retained Sponsor Shares are subject to a lock-up whereby, subject to certain limited exceptions, the Retained Sponsor Shares are not transferable until the earlier of (A) the Anniversary Release; provided that, if the VWAP of the shares of Pubco Class A Stock equals or exceeds $12.50 per share for any 20 consecutive trading days after Closing, then the Anniversary Release will be deemed to occur at 11:59 p.m. (New York City time) on such 20th consecutive trading day, or (B) subsequent to MLAC’s initial business combination, the date on which Pubco consummates a transaction which results in all of its shareholders having the right to exchange their shares for cash, securities or other properties. The Sponsor may, on or before the Closing of the Business Combination, distribute some or all of the Retained Sponsor Shares held by it and such distributed Retained Sponsor Shares may be released from lock-up restrictions in connection with applicable stock exchange listing requirements. In this regard, while the Retained Sponsor Shares are not the same as the MLAC Class A Ordinary Shares, are subject to certain restrictions that are not applicable to the MLAC Class A Ordinary Shares, and may become worthless if MLAC does not complete a business combination by June 16, 2026 (or such other date as approved by the MLAC Shareholders), the aggregate value of the 2,800,000 Retained Sponsor Shares owned by the Sponsor is estimated to be approximately $29.62 million, assuming the per share value of the Retained Sponsor Shares is the same as the $10.58 closing price of the MLAC Class A Ordinary Shares on Nasdaq on May 5, 2026;

• the Sponsor has agreed that the 1,600,000 shares of Pubco Class A Stock to be issued to the Sponsor (of the total 2,800,000 Retained Sponsor Shares it will hold), will be held in escrow during the Earnout Period, subject to early release upon certain price-based Triggering Events. Additionally, any Retained Sponsor Shares that are released from escrow shall not be sold or transferred until the Anniversary Release;

• the 495,000 MLAC Private Placement Shares held by the Sponsor (or any permitted distributees thereof, as applicable) will be forfeited immediately prior to the Closing pursuant to the Sponsor Support Agreement. The Sponsor purchased the MLAC Private Placement Shares at an aggregate purchase price of $4,950,000, or $10.00 per unit, in the Private Placement consummated simultaneously with the MLAC IPO. The aggregate value of the 495,000 MLAC Private Placement Shares

119

held by the Sponsor is estimated to be approximately $5.24 million, assuming the per unit value of the MLAC Private Placement Shares is the same as the $10.58 closing price of the MLAC Class Ordinary Shares on Nasdaq on May 5, 2026;

• if the proposed Business Combination is consummated, immediately after the Closing the Sponsor and its Affiliates are anticipated to hold 4.9% of the outstanding shares of Pubco Common Stock, based on the assumptions set forth in the section of this proxy statement/prospectus entitled
“Share Calculations and Ownership Percentages,” which also incorporate relevant assumptions
further described in the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information” and “Beneficial Ownership of Securities” and assuming, among other assumptions further described in aforementioned sections of this proxy statement/ prospectus, no redemptions of Public Shares and no conversion of public share rights or private share rights prior to or in connection with the proposed Business Combination;

• based on the difference in the effective purchase price of $0.003 per share paid for the MLAC Class B Ordinary Shares, as compared to the purchase price of $10.00 per Unit sold in the MLAC IPO, the Sponsor and its members may earn a positive rate of return even if the share price of Pubco Stock after the Closing falls below the price initially paid for the MLAC Units in the MLAC IPO and the unredeeming unaffiliated Public Shareholders experience a negative rate of return following the Closing of the Business Combination;

• if, prior to the Closing, the Sponsor provides working capital loans to MLAC, up to $1,500,000 of which may be convertible into MLAC Private Placement Shares at the option of the Sponsor, such loans may not be repaid if no business combination is consummated and MLAC is forced to liquidate; provided, however, that, as of the date of this proxy statement/prospectus, there are no such working capital loans outstanding;

• unless MLAC consummates an initial business combination, it is possible that MLAC’s officers, directors and the Sponsor may not receive reimbursement for out-of-pocket expenses incurred by them, to the extent that such expenses exceed the amount of available funds not deposited in the Trust Account (provided, however, that, as of the date of this proxy statement/ prospectus, MLAC’s officers and directors have not incurred (nor are any of them expecting to incur) out-of-pocket expenses exceeding such funds available to MLAC for reimbursement thereof, but provided, further, that if any such expenses are incurred prior to consummation of the Business Combination, MLAC’s officers, directors and the Sponsor may not receive reimbursement therefor if the proposed Business Combination is not consummated);

• if the Trust Account is liquidated, including in the event MLAC is unable to complete an initial business combination by June 16, 2026 (or such other date as approved by the MLAC Shareholders), the Sponsor has agreed that it will be liable to MLAC, if and to the extent any claims by a third party for services rendered or products sold to MLAC (except for MLAC’s independent auditors) or a prospective target business with which MLAC has entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per share due to reductions in the value of the trust assets less taxes payable, provided, however, that such liability will not apply to any claims by a third party or prospective target business that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable), nor will it apply to any claims under MLAC’s indemnity of the underwriters of the MLAC IPO against certain liabilities, including liabilities under the Securities Act;

• the Sponsor and its Affiliates may benefit from the completion of a business combination and may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to shareholders rather than liquidate;

• MLAC agreed to pay Paul Grinberg, MLAC’s Chairman and Chief Executive Officer and Douglas Horlick, MLAC’s President and Chief Financial Officer, an aggregate of up to $20,000 per month for their services as executive officers and directors of MLAC, until the earlier to occur of the completion of MLAC’s initial business combination or its liquidation. As of December 31, 2025, MLAC has incurred and paid an expense of $240,000 of such fee; and

• MLAC’s officers and directors will be eligible for continued indemnification and continued coverage under a tail policy for MLAC’s directors’ and officers’ liability insurance policy for up to a six-year period from and after the Closing for events occurring prior to the Closing, which tail policy is to be paid for by Pubco at the Closing pursuant to the Business

120

Combination Agreement. If the Business Combination does not close, MLAC’s officers and directors may not receive this tail insurance coverage.

• the anticipated election of Mr. Grinberg, MLAC’s Chairman and Chief Executive Officer, as director of Pubco after the consummation of the Business Combination. As such, in the future, such directors will receive any cash fees, stock options or stock awards that the Pubco Board determines to pay to such directors.

• in addition to the interests of the Sponsor and its Affiliates in the Business Combination, MLAC Shareholders should be aware that MLAC’s underwriter for its IPO, BTIG, may also have financial interests that are different from, or in addition to, the interests of MLAC Shareholders, including the fact that:

• pursuant to an amendment to the underwriting agreement in connection with MLAC’s IPO, BTIG may receive a deferred fee equal to $1,000,000, and such fees are payable at the closing of the Business Combination only if MLAC completes the Business Combination; and pursuant to the Sponsor Support Agreement, BTIG will forfeit its 310,000 MLAC Private Placement Shares; and

• pursuant to the BTIG Financial Advisory Services Agreement, BTIG may receive reimbursement of all reasonable out-of-pocket expense as financial advisor to MLAC in connection with the Business Combination, (provided that, if the expense exceeding $100,000, BTIG shall submit to MLAC for its prior written approval), such reimbursement are payable at the closing of the Business Combination only if MLAC completes an initial business combination;

The MLAC Board reviewed and considered the potential conflicting interests described above with respect to the Sponsor and Affiliates and, after taking into account the factors they deemed applicable (including the potential conflicting interests), unanimously approved the Business Combination Agreement and the transactions contemplated therein.

For more information, see “Certain Relationships and Related Party Transactions” and see the risk factor entitled “Risk Factors — Risks Related to the Business Combination — Since the Sponsor and its Affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of Public Shareholders, a conflict of interest may have existed in determining whether the Business Combination with Pubco and the Company is appropriate as MLAC’s initial business combination. Such interests include that the Sponsor and Affililates will lose their entire investment in MLAC if the Business Combination is not completed or any other business combination is not completed.”

Representations and Warranties

The Business Combination Agreement contains customary representations and warranties of the parties, which shall not survive the Closing. Certain representations and warranties are qualified by materiality or Material Adverse Effect.

With respect to point (i), the following changes or effects (by themselves or when aggregated with others) are not considered a Material Adverse Effect:

(a) general changes in financial or securities markets (including interest rates) or general economic or political conditions in the country or region where the party or its subsidiaries do business;

(b) changes, conditions, or effects that generally affect the industries or markets in which the party or its subsidiaries principally operate;

(c) changes in the price or trading volume of AVAX (provided that the underlying cause of any such event, occurrence, change or effect in the price or trading volume may be considered in determining whether a Material Adverse Effect has occurred or would reasonably be expected to occur to the extent not excluded by another exception);

(d) any proposal, enactment, or change in interpretation of, or any other change in, applicable laws, IFRS, U.S. GAAP, or other applicable accounting principles or mandatory changes in the regulatory accounting requirements applicable to any industry in which such party and its subsidiaries principally operate;

The exceptions in letters (a), (b), (c), (d), (e), and (g) above will be taken into account in determining whether a Material Adverse Effect has occurred or could reasonably be expected to occur to the extent that such event, occurrence, fact, condition, or change has a disproportionate and adverse effect on such party or any of its subsidiaries compared to similarly situated participants in the industries in which such party or any of its subsidiaries primarily conducts its businesses.

Notwithstanding the foregoing, for MLAC, the number of MLAC Ordinary Shares redeemed in connection with the Business Combination or the failure to obtain the Required Shareholder Approval shall not, in and of itself, be deemed a Material Adverse Effect on or with respect to MLAC, provided that the underlying causes of any such redemptions or failure to obtain the Required Shareholder Approval may be considered if not otherwise excluded by another exception and provided, further, with respect to the failure to obtain the Required Shareholder Approval, that the MLAC has not violated its obligations under this Agreement in connection with obtaining such Required Shareholder Approval.

Each party agreed that all rights to exculpation, indemnification and advancement of expenses existing in favor of the current or former directors and officers of MLAC, the Company, Pubco, or the Pubco Subsidiaries (the “D&O Indemnified Persons”) as provided in their respective organizational documents or under any indemnification, employment or other similar agreements between any D&O Indemnified Person and MLAC, any Pubco Subsidiary, the Company or Pubco will survive the Closing. For a period of six (6) years after the Company Merger Effective Time, Pubco’s, the Company Surviving Subsidiary’s, and the MLAC Surviving Subsidiary’s organizational documents will contain provisions no less favorable with respect to exculpation and indemnification of and advancement of expenses to D&O Indemnified Persons than are set forth in such documents as of the date of the Business Combination Agreement.

In addition, from and after the Company Merger Effective Time, Pubco shall, to the fullest extent permitted by applicable law, indemnify and hold harmless, and provide advancement of expenses to, each of the D&O Indemnified Persons against any costs, expenses (including attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any action or omission performed in such D&O Indemnified Person’s capacity as a director or officer of MLAC, the Company, Pubco or any Pubco Subsidiary, occurring or alleged to have occurred at or prior to the Company Merger Effective Time, whether asserted or claimed prior to, at or after the Company Merger Effective Time. Those covenants survive the Closing.

Prior to the MLAC Merger Effective Time, MLAC has agreed to obtain, and Pubco has agreed to fully pay the premium for, a “tail” insurance policy under MLAC’s existing insurance policy for the benefit of MLAC’s directors and officers that provides coverage for up to six (6) years from and after the MLAC Merger Effective Time for events occurring prior to the MLAC Merger Effective Time (the “D&O Tail Insurance”), on terms substantially equivalent to and in any event not less favorable in the aggregate than MLAC’s existing coverage, subject to certain limitations.

Other Transaction Agreements

Contribution Agreement

Concurrently with the execution of the Business Combination Agreement, Seller, the Company, Pubco, Avalanche BVI and Avalanche Cayman entered into the Contribution Agreement, pursuant to which, on the date of the Business Combination Agreement, (i) the Foundation agreed to perform the Foundation Transaction on the terms and subject to the conditions set forth in the Token Sale Agreement and (ii) Seller agreed to perform the Dragonfly Contribution by contributing, directly or indirectly through the Funds, 1,960,040 AVAX tokens (the “Foundation Tokens”) to the Company in exchange for 5,805,638 Company Units.

134

The Contribution Agreement also contains certain covenants of the parties, as set out below:

(a) Outreach and Management. Seller has agreed to identify and engage potential acquisition targets, additional Advisory Board members, co-asset managers, and prospective management team members for the Company. The parties have further agreed that Mr. Gerald Bartholomew Smith will serve as the Chief Executive Officer of the Company.

(b) Marketing and Communications. Seller and the Company will ensure that all marketing materials and investment documentation relating to the Company, the Avalanche ecosystem and the Foundation are consistent with the terms of the Contribution Agreement and all information publicly disclosed by the Foundation. Seller will consider in good faith any timely comments or observations provided by the Foundation with respect to such materials.

(c) Exclusivity and the Company’s Right of First Refusal.  For a period of eighteen (18) months commencing on the date of the Business Combination Agreement (the “Covered Period”), the Foundation shall not directly or indirectly, and will direct its directors, officers and employees not to, enter into any binding agreement to enter into a “Competing Transaction,” i.e., any sale of AVAX to any digital asset treasury vehicle (or a subsidiary or affiliate of any such vehicle) that has taken substantial steps to be listed (including by way of a reverse takeover of, or private investment into, an existing public company or a de-SPAC) on a U.S. national stock exchange with the sole operations or primary business model being dependent on owning AVAX or to any vehicle that is intended to be combined with or in the formation of a DAT. During the Covered Period, the Company will have a right of first refusal with respect to any proposed sale, that is not a Competing Transaction, by the Foundation of AVAX in one single transaction or a series of related transactions in each case to a single purchaser or group of Affiliated purchasers with an aggregate value to such purchaser or group of Affiliated purchasers (other than any sales to a bona fide person or entity entering into an arrangement with a Foundation entity to acquire or utilize AVAX in connection with a strategic, business or operational purpose, not, to purchase AVAX primarily for investment, capital markets related or market making purposes) exceeding $75 million at a price representing a discount greater than 30% (based on the then-current/weighted 30-day trailing market price of AVAX), subject to specified notice, timing, and acceptance procedures. This right of first refusal will terminate automatically if the Company fails to list on a U.S. national securities exchange by April 30, 2026, with at least $300 million in AVAX assets and $100 million in cash or cash equivalents. Notwithstanding the foregoing, the Foundation may conduct a one-time sale or contribution of tokens in connection with the launch of specific other projects detailed in the Contribution Agreement.

(d) Board Representation. For a period of five (5) years following the Closing Date, the Foundation will be entitled to designate one individual for appointment to the board of directors of Pubco. Seller, Pubco and the Company have agreed to take all actions necessary to effect such appointment. In the event that, after the expiration of the Covered Period but prior to the expiration of this initial five-year period, the Foundation sells or transfers additional AVAX to Pubco, the Company or their Affiliates in a transaction comparable in size and discount to the Foundation Transaction (a “Subsequent Token Sale”), the Foundation’s board designation right will be extended for additional three (3) years. Each Subsequent Token Sale will further extend this right for an additional three-year period.

(e) Foundation Right of First Refusal. For a period of five (5) years commencing on the date of the Business Combination Agreement, the Foundation will have a right of first refusal with respect to any proposed sale by the Company of Foundation Tokens in one or more related transactions with an aggregate value exceeding $1 million. The Company must provide written notice to the Foundation of any such proposed sale within five (5) days from the receipt of a bona fide binding offer to sell directly any Foundation Token, and the Foundation will have ten (10) calendar days to elect to purchase all, but not less than all, of the tokens on the same terms as offered by the third-party purchaser. If the Foundation does not exercise its right within the prescribed period, the Company may complete the sale at a price not less than that set forth in the notice.

(f) Tokenization. The Company and Pubco have agreed that any issuance, sale or distribution of crypto assets relating to their respective shares, assets or any network, protocol or application developed by or on their behalf will be conducted exclusively on the Avalanche blockchain.

135

The Contribution Agreement has an indefinite term, but may be terminated prior to the Closing as follows: (a) by the mutual written consent of Seller, the Company, Pubco, Avalanche BVI and Avalanche Cayman; or (b) by the Foundation, if the Transaction fails to close or Pubco fails to list on a U.S. national stock exchange by September 30, 2026, in each case with assets of at least $300 million in AVAX plus $100 million in cash or cash equivalents. If the Business Combination Agreement is terminated, the Contribution Agreement shall automatically terminate.

If the Contribution Agreement is terminated, the Token Sale Agreement will become void and of no further force and effect, and the Foundation AVAX sold by the Foundation to the Company under the Foundation Transaction and the AVAX contributed by the Funds to the Company under the Dragonfly Contribution will be returned to the Foundation and the Funds, respectively, in the same form in which they were sold or contributed, and any consideration received by the Foundation or the Funds will be returned to the Company.

The Contribution Agreement may be terminated prior to the Closing as follows: (a) by the mutual written consent of Seller, the Company, Pubco, Avalanche BVI and Avalanche Cayman; or (b) by the Foundation, if the Transaction fails to close or Pubco fails to list on a U.S. national stock exchange by September 30, 2026, in each case with assets of at least $300 million in AVAX plus $100 million in cash or cash equivalents. If the Business Combination Agreement is terminated, the Contribution Agreement shall automatically terminate.

If the Contribution Agreement is terminated, the same Contribution Agreement and the Token Sale Agreement will become void and of no further force and effect, and the Foundation AVAX sold by the Foundation to the Company under the Foundation Transaction and the AVAX contributed by the Funds to the Company under the Dragonfly Contribution will be returned to the Foundation and the Funds, respectively, in the same form in which they were sold or contributed, and any consideration received by the Foundation or the Funds will be returned to the Company.

In addition, the Contribution Agreement includes specific indemnity obligations. In particular, (i) Seller, the Company, and Pubco have undertaken to defend and indemnify the Foundation and its affiliates against third-party claims caused by their breach of the Contribution Agreement (excluding token sale claims), except where the Foundation acted in bad faith, with gross negligence or intentional misconduct. Indemnity is paid as costs are incurred; and (ii) the Foundation must defend and indemnify Seller, the Company, and their affiliates against third-party claims caused by the Foundation’s breach of its representations and warranties (excluding token sale claims), except where Seller acted in bad faith, with gross negligence, or intentional misconduct. Indemnity is paid as costs are incurred.

Token Sale Agreement

Concurrently with the execution of the Business Combination Agreement, the Company, Pubco, Avalanche BVI, and Avalanche Cayman entered into the Token Sale Agreement, pursuant to which, on the date of the Business Combination Agreement, the Foundation agreed to perform the Foundation Transaction, by selling a minimum of $200 million of AVAX on a pre-discount basis to the Company in exchange for, at a 60% discount, $50 million in cash or USDC and $30 million in the form of up to 3,000,000 shares of Pubco Class A Stock to be issued at Closing (the “Foundation Shares”).

The Token Sale Agreement imposes certain limitations on the transfer and use of Foundation Token. In particular, the Company, for a period of 5 (five) years from the date of the Business Combination Agreement, shall not transfer, sell, pledge (except for certain permitted collateral pledges) or otherwise dispose of the Foundation Tokens without the Foundation’s prior written consent.

If at any time following the Closing Date, the Pubco Class A Stocks cease to be nonvoting securities and at such time the Foundation owns a number of Foundation Shares in excess of 4.7% of the then-outstanding Pubco Class A Stock (the “Maximum Percentage”), the Foundation may request to exchange the number of Foundation Shares in excess of the Maximum Percentage for an equal number of pre-funded warrants convertible, at the Foundation’s request, into Pubco Class A Stock on a one-to-one basis, and the Company shall issue such number of pre-funded warrants convertible into Pubco Class A stock, prior to the time the Pubco Class A Stock converts into voting securities.

Pursuant to the Token Sale Agreement, AVAT and Pubco undertakes to defend and indemnify the Foundation and its respective agents, advisors, successors and assigns from and against all causes of actions or third-party claims arising out of, or resulting from, or relating to, the Foundation Transaction, including any breach of the Token Sale Agreement by the purchaser and/or Pubco and any action or omission of the Purchaser and/or Pubco, except for the Foundation’s bad faith or gross negligence.

Sponsor Support Agreement

Concurrently with the execution of the Business Combination Agreement, MLAC, Sponsor and Pubco entered into the Sponsor Support Agreement, pursuant to which, among other things, the Sponsor agreed (i) to vote its MLAC Ordinary Shares in favor of the Business Combination Agreement and the Transactions and the Business Combination Proposal, (ii) to vote its MLAC Ordinary Shares against (a) any Acquisition Proposal or Alternative Transaction, (b) any merger, consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by MLAC (other than the Transactions), (c) any change in the business of MLAC, and (d) any proposal, action or agreement involving MLAC that would or would reasonably be expected to jeopardize the Transactions, (iii) to comply with the restrictions imposed by the letter agreement, dated as of

137

December 12, 2024, by and among MLAC, the Sponsor, and the officers and directors of MLAC at the time of the MLAC IPO (the “Insider Letter”), including the restrictions on transfer and redemption of MLAC Ordinary Shares in connection with the Transactions and (iv) subject to and conditioned upon the consummation of the MLAC Merger, to waive any anti-dilution rights that would otherwise result in the MLAC Class B Ordinary Shares held by Sponsor converting into MLAC Class A Ordinary Shares on a greater than one-for-one basis.

In addition, the Sponsor agreed to effect certain security cancellations and to deposit certain Pubco Class A Stock issued to it at Closing into escrow in connection with the Closing. Specifically, immediately prior to the MLAC Merger Effective Time, the Sponsor will (i) deliver to MLAC for cancellation, 495,000 MLAC Private Placement Shares and 4,387,500 MLAC Founder Shares, and (ii) 1,600,000 Sponsor Earnout Shares will be deposited into an escrow account with Continental Stock Transfer and Trust Company and will be released in tranches as provided in the Sponsor Support Agreement and an escrow agreement that shall be in a form to be mutually agreed upon by the Sponsor, Pubco and the escrow agent prior to the Closing (the “Sponsor Escrow Agreement”). The Sponsor agreed that all of the Sponsor Earnout Shares, together with any shares received upon equitable adjustment of the Sponsor Earnout Shares, shall be subject to potential transfer to Pubco (the “Sponsor Transfer”) at the end of the Earnout Period in the event that not all of the Triggering Events are achieved by Pubco.

The Sponsor Earnout Shares shall vest, no longer be subject to the Sponsor Transfer and shall be released from the escrow account to the Sponsor, in the amounts specified below, upon Pubco meeting the price milestones specified below:

(a) Upon the occurrence of Triggering Event I, 533,333 Sponsor Earnout Shares shall be released from the escrow account to the Sponsor;

(c) Upon the occurrence of Triggering Event III, 533,334 Sponsor Earnout Shares shall be released from the escrow account to the Sponsor.

Notwithstanding the foregoing, in the event that during the Earnout Period, Pubco is subject to a Change in Control, then all of the Sponsor Earnout Shares, together with any shares received upon equitable adjustment of the Sponsor Earnout Shares, then remaining in the escrow account shall no longer be subject to the Sponsor Transfer and shall be released to the Sponsor from the escrow account.

Pursuant to the Sponsor Support Agreement, the parties agreed that prior to the Closing they would enter into an amendment to the Insider Letter to amend certain terms relating to transfer restrictions applicable to the shares held by the Sponsor.

The Sponsor also agreed to use its reasonable best efforts to cause BTIG to forfeit all deferred underwriting fees in excess of $1,000,000 and to use reasonable efforts to cause BTIG to deliver all of the 310,000 MLAC Private Units it holds for cancellation. Further, the Sponsor also agreed, subject to and effective as of the Closing, to irrevocably and unconditionally release and waive any and all claims it may have against MLAC, Pubco and the Company or their respective Affiliates arising on or prior to the Closing, subject to customary carve-outs.

The Sponsor Support Agreement and certain of its provisions will terminate and be of no further force or effect upon the earlier to occur of the Closing and the valid termination of the Business Combination Agreement pursuant to its terms and, if the Business Combination Agreement is terminated pursuant to its terms, all provisions of the Sponsor Support Agreement will terminate and be of no further force or effect.

Amended and Restated Registration Rights Agreement

Concurrently with the Closing, Pubco, MLAC, the Sponsor, Seller Related Parties, Astral, the Foundation and certain securityholders shall enter into the Amended and Restated Registration Rights Agreement, which will amend and restate the MLAC Registration Rights Agreement and pursuant to which Pubco will (i) assume the registration obligations of MLAC under such registration rights agreement, with such rights applying to the shares of Pubco Class A Stock and (ii) provide registration rights with respect to the resale of shares of Pubco Class A Stock held by the parties thereto. The Amended and Restated Registration Rights Agreement provides for customary demand registration rights, piggyback registration rights and shelf registration rights for the benefit

of the holders of Pubco Stock named therein, subject to customary cutbacks and issuer suspension rights. The Amended and Restated Registration Rights Agreement also includes customary provisions relating to underwriting participation, registration expenses, indemnification and coordination of sales in underwritten offerings, and will become effective upon the Closing. The Amended and Restated Registration Rights Agreement will supersede MLAC’s existing registration rights agreement in its entirety.

Pubco estimates that up to approximately 15,605,638 shares of Pubco Class A Stock will be subject to registration rights pursuant to the Amended and Restated Registration Rights Agreement immediately following the Closing, representing approximately 25% of the total issued and outstanding shares of Pubco Class A Stock following the Transactions, and assuming, among other things, that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination that no shares of Pubco Class A Stock are issued pursuant to the Incentive Plan and that no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements.

Lock-Up Agreement

Concurrently with the Closing, (i) MLAC, Sponsor and the MLAC Insiders will enter into with Pubco the Sponsor Lock-Up Agreement and (ii) the Funds, Astral and certain other holders of shares of Pubco Stock will also enter into with Pubco the Seller Lock-Up Agreements in substantially the same form as the Sponsor Lock-Up Agreement, pursuant to which such parties will agree that the shares of Pubco Class A Stock received by them in connection with the Business Combination, and any other securities such parties hold that are convertible into or exercisable or exchangeable for Pubco Stock, (the “Restricted Securities”) will be subject to transfer restrictions, as described below.

Under the Lock-Up Agreements, the Restricted Securities will be subject to transfer restrictions until the earlier of (i) 180 days following the date of the Closing (the “Anniversary Release”); provided, that if the VWAP of Pubco Class A Stock equals or exceeds $12.50 per share for any 20 consecutive trading days following the Closing, the Anniversary Release will be deemed to occur at 11:59 p.m. New York City time on such 20th consecutive trading day, and (ii) the date on which Pubco consummates a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all Pubco shareholders having the right to exchange their shares of Pubco Stock for cash, securities or other property (the “Lock-Up Period”).

The foregoing lock-up restrictions do not apply to the following permitted transfers so long as the transferee of such permitted transfer executes and delivers to Pubco (a) all agreements and waivers contemplated by the Insider Letter (if any); and (b) an agreement stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of the Lock-Up Agreement and that Restricted Securities will not be transferred any further:

(a) in the case of an entity, transfers (A) to another entity that is an Affiliate of the original holder of the Restricted Securities, (B) as part of a distribution to members, partners or stockholders of the Holder and (C) to officers or directors of the Holder, any Affiliate or family member of any of the Holder’s officers or directors, or to any members, officers, directors or employees of the Holder or any of its Affiliates;

(b) in the case of an individual, transfers by gift to members of the individual’s immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, or an Affiliate of such person;

(c) to a charitable organization;

(d) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual;

(e) in the case of an individual, transfers pursuant to a qualified domestic relations order;

(f) in the case of an entity, transfers by virtue of the laws of the state of the entity’s organization and the entity’s organizational documents upon dissolution of the entity;

139

(g) transfers to satisfy any U.S. federal, state, or local income tax obligations of Seller (or its direct or indirect owners) to the extent necessary to cover any tax liability as a direct result of the Transactions; or

(h) transfers in the form of a pledge of Restricted Securities in a bona fide transaction as collateral to secure obligations pursuant to lending or other financing arrangements between the Holder (or its Affiliates), on the one hand, and a third party, on the other hand, for the benefit of the Holder and/or its Affiliates, provided, however, that during the period Restricted Securities are locked up, such third party shall not be permitted to foreclose upon such Restricted Securities or otherwise be entitled to enforce its rights or remedies with respect to the Restricted Securities, including, without limitation, the right to vote, transfer or take title to or ownership of such Restricted Securities.

Any transfer in violation of the Lock-Up Agreements will be null and void, and Pubco is authorized to impose stop-transfer instructions with respect to any such Restricted Securities during the Lock-Up Period.

The Company Unit Subscription Agreements

Concurrently with the execution of the Business Combination Agreement, Pubco, the Company and MLAC entered into the Company Unit Subscription Agreements with the Company Unit Investors, pursuant to which the Company Unit Investors agreed to purchase, payable in cash, USDC, AVAX that is neither locked nor staked (“Unrestricted AVAX”), AVAX that will become Unrestricted after October 1, 2026 (“Long Restricted AVAX”) or AVAX that will become Unrestricted on or prior to October 1, 2026 (“Short Restricted AVAX”) (or a combination of cash, USDC and/or AVAX), and the Company agreed to issue and sell, approximately $216 million worth of Company Units at the Per Unit Price, upon the terms and subject to the conditions set forth therein.

Company Unit Investors received a number of Company Units equal to (a) if the Company Unit Investor elected to purchase Company Units by contributing AVAX, the Stated AVAX Amount multiplied by the Applicable Signing AVAX Price, or (b) if the Company Unit Investor elected to purchase the Company Units by contributing cash or USDC, the Stated Dollar Amount or the Stated USDC Amount (as applicable), in each case divided by the Per Unit Price. Each Company Unit Investor was required to fund its respective cash or USDC within three business days following the execution date of the Company Unit Subscription Agreement, and to fund its respective AVAX as soon as reasonably possible after the execution date of the Company Unit Subscription Agreement, and in any case on or prior to November 7, 2025, in accordance with the terms of the Company Unit Subscription Agreements.

Immediately prior to the Company Merger Effective Time, the number of Company Units issued to the Company Unit Investors will be adjusted as follows: (x) if the Closing AVAX Price is greater than the Unrestricted Signing AVAX Price, the Company shall issue to each Company Unit Investor such number of Company Units equal to the product of (i) the number of Company Units issued to such Company Unit Investor at the Subscription Closing Date and (ii) the difference between (1) the quotient of the Closing AVAX Price and the Unrestricted Signing AVAX Price and (2) one; and (y) the Company shall issue to each Company Unit Investor such number of Company Units equal to such Company Unit Investor’s pro rata portion of the Aggregate Staking Units, based on such Company’ Unit Investor’s Company Units relative to the aggregate Company Units of all Company Unit Investors (the “Adjustment Units”). “Closing AVAX Price” means the VWAP of AVAX denominated in USD as calculated from all executed trades on Binance (or its successor primary spot exchange) over the five-day period ending at 8:00 p.m. New York City time on the day immediately prior to the Closing Date. “Net Staking Rewards” means the total amount of AVAX generated as staking rewards from the staking of the Company AVAX from the Subscription Closing Date until the date immediately prior to the Closing Date and after deducting any and all applicable staking fees, network transaction fees and operational costs directly attributable to such staking. “Aggregate Staking Units” means such number of Company Units equal to the quotient of (x) the Net Staking Rewards multiplied by the Closing AVAX Price and (y) the Per Unit Price.

At the Company Merger Effective Time, each Company Unit held by Company Unit Investors will be converted automatically into one share of Pubco Class A Stock.

The closing of the Company Unit Subscription is contingent upon the satisfaction of all closing conditions to consummate the Transactions and the Company Unit Investors’ consent to any amendments, modifications or waivers to the terms of the Business Combination Agreement that would reasonably be expected to materially and adversely affect the economic benefits of the Company Unit Investors, among other customary closing conditions.

140

Pursuant to the Company Unit Subscription Agreements, Pubco has agreed to certain obligations to register and maintain the registration of the shares of Pubco Class A Stock into which the Company Units will be converted after consummation of the Transactions including that, within 30 calendar days after the Closing, Pubco will file or confidentially submit with the SEC (at Pubco’s sole cost and expense) a registration statement registering the resale of such shares of Pubco Class A Stock, and Pubco shall use its commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing or confidential submission thereof, but no later than 90 calendar days after the Closing, which may be extended an additional 90 calendar days depending on the extent of the SEC’s review.

Each Company Unit Subscription Agreement shall terminate and be void and of no further force and effect upon the earliest to occur of (i) such date and time as the Business Combination Agreement is terminated in accordance with its terms, (ii) the mutual written agreement of the respective parties to terminate such agreement or (iii) October 1, 2026.

Agreements with PJT and Barclays

On September 12, 2025, AVAT entered into the Private Placement Engagement Letter, pursuant to which AVAT engaged PJT and Barclays to provide certain capital markets advisory services and to act as exclusive placement agents for the Company Unit Subscription. For the services provided thereto, PJT and Barclays will receive a cash fee at the Closing, which is equal to 5.5% of the aggregate gross cash proceeds from the sale of equity or equity-linked securities of AVAT to institutional accounts, with such placement fee split equally between PJT and Barclays. Additionally, if the Company sells any equity or equity-linked securities of AVAT (or securities of the same or a similar class) within twelve (12) months following any termination of the Private Placement Engagement Letter, then the Company will pay to PJT and Barclays a fee at the closing that is equal to the fee which would have been payable to PJT and Barclays if the closing occurred during the term of the appointment. PJT and Barclays are entitled to be indemnified by AVAT pursuant to certain customary indemnity provisions under the Private Placement Engagement Letter.

On September 12, 2025, AVAT entered into the Financial Advisor Engagement Letter, pursuant to which AVAT engaged PJT as its exclusive financial advisor in connection with the Business Combination and PJT agreed to perform customary financial advisory services. For its services under the Financial Advisor Engagement Letter, PJT will receive a customary advisory fee payable in cash promptly at, and conditional upon, the Closing. PJT is entitled to be indemnified by AVAT pursuant to certain customary indemnity provisions under the Financial Advisor Engagement Letter.

Required Vote and Recommendation of the MLAC Board

The Closing is conditioned on, among other things, the approval of the Business Combination Proposal at the Meeting. The consummation of the Business Combination will require an ordinary resolution, being a resolution passed at the Meeting by the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). Abstentions and broker non-votes will be counted towards the quorum requirement but will not have an effect on the Business Combination Proposal.

The Sponsor has agreed to vote its MLAC Ordinary Shares in favor of the adoption and approval of the Business Combination Agreement and the Business Combination and each of the MLAC Shareholder Approval Matters as described above under “The Business Combination Proposal — Other Transaction Agreements — Sponsor Support Agreement.”

THE MERGER PROPOSAL

Overview

In connection with the Business Combination, MLAC Shareholders are being asked to consider and vote upon a proposal by special resolution to approve and authorize the MLAC Merger.

Under the Business Combination Agreement, the approval by MLAC Shareholders of the Business Combination Proposal and the Merger Proposal is a condition to the consummation of the Business Combination. If either of those Proposals is not approved by MLAC Shareholders, the Business Combination will not be consummated. The Merger Proposal is conditioned upon the approval of the Business Combination Proposal. The Domestication and Organizational Documents Proposals and the Nasdaq Proposal are conditional upon the approval of the MLAC Shareholder Approval Matters. The Director Election Proposal and the Adjournment Proposal are not conditioned on the approval of any other Proposal.

Reasons for the MLAC Merger

The authorization of the MLAC Merger requires the approval of MLAC Shareholders by special resolution under the MLAC Memorandum and Articles.

Appraisal Rights

MLAC Shareholders do not have appraisal rights in connection with the Business Combination under the DGCL or the Cayman Act.

Required Vote and Recommendation of the MLAC Board

The Closing is conditioned on, among other things, the approval of the Merger Proposal. The approval of the Merger Proposal will require a special resolution, being a resolution passed at the Meeting by the affirmative vote of at least two-thirds of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). Abstentions and broker non-votes will be counted towards the quorum requirement but will not have an effect on the Merger Proposal. The adoption of the Merger Proposal is conditioned upon the adoption of the Business Combination Proposal.

The Sponsor has agreed to vote its MLAC Ordinary Shares in favor of the adoption and approval of the Business Combination Agreement and the Business Combination and each of the MLAC Shareholder Approval Matters as described above under “The Business Combination Proposal — Other Transaction Agreements — Sponsor Support Agreement.”

The full text of the resolution to be passed is as follows:

“RESOLVED, as a special resolution, that MLAC be authorized to merge with and into Avalanche SPAC Merger Sub LLC, a Delaware limited liability company (“MLAC Merger Sub”) so that MLAC be the surviving company and all the undertaking, property and liabilities of MLAC Merger Sub vest in MLAC by virtue of such merger pursuant to the applicable provisions of the General Corporation Law of the State of Delaware (the “DGCL”) and the Limited Liability Company Act of the State of Delaware (the “DLLCA”).”

THE MLAC BOARD UNANIMOUSLY RECOMMENDS THAT MLAC SHAREHOLDERS VOTE

“FOR” THE APPROVAL OF THE MERGER PROPOSAL.

The existence of financial and personal interests of one or more of MLAC’s directors may result in a conflict of interest on the part of such director(s) between what they may believe is in the best interests of MLAC and the MLAC Shareholders and what they may believe is best for himself, herself or themselves in determining to recommend that MLAC Shareholders vote for the Proposals. See the section entitled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and its Affiliates in the Business Combination” for a further discussion.

143

THE DOMESTICATION AND ORGANIZATIONAL DOCUMENTS PROPOSALS

Overview

As SEC guidance requires that MLAC Shareholders have the opportunity to present their views on important corporate governance provisions, MLAC is requesting that MLAC Shareholders vote, on a non-binding advisory basis, by ordinary resolution, to approve the Domestication and certain governance provisions in the Proposed Organizational Documents, which are separately being presented. These separate votes are not otherwise required by Cayman Islands law or Delaware law. Accordingly, the MLAC Shareholder votes regarding the Domestication and Organizational Documents Proposals are advisory votes, not binding on MLAC or the MLAC Board. Furthermore, the Business Combination is not conditioned on the separate approval of the Domestication and Organizational Documents Proposals. Accordingly, regardless of the outcome of the non-binding advisory vote on the Domestication and Organizational Documents Proposals, the Amended and Restated Pubco Certificate of Incorporation will take effect upon the Closing.

The Domestication and Organizational Documents Proposals present the following Proposed Organizational Documents that materially differ from the MLAC Memorandum and Articles:

(1) Proposal A: the registration of MLAC will be transferred by way of continuation from the Cayman Islands to the State of Delaware.

(2) Proposal B: the authorized capital stock of Pubco will consist of 550,000,000 Pubco Class A Stock, 100,000,000 Pubco Class B Stock and 50,000,000 shares of preferred stock.

(3) Proposal C: the size and composition of the board of directors will be changed to consist of one (1) or more members, each of whom shall be a natural person.

(4) Proposal D: the Proposed Organizational Documents will provide for an unclassified Pubco Board.

(5) Proposal E: the Proposed Organizational Documents will not include provisions related to Pubco’s status as a blank check company because Pubco is not a blank check company.

The following table sets forth a summary of the principal material differences between the MLAC Memorandum and Articles and the Proposed Organizational Documents. This summary is qualified by reference to the complete text of the MLAC Memorandum and Articles and the Proposed Organizational Documents, the form of which is attached to this proxy statement/prospectus as Annexes B and C. You are encouraged to read the Proposed Organizational Documents in their entirety for a more complete description of the terms of the Proposed Organizational Documents.

Proposal	MLAC Memorandum and Articles	Proposed Organizational  Documents
(A) Domestication	Under MLAC’s current articles of association, MLAC has the power to register by way of continuation as a body corporate under the laws of any jurisdiction outside the Cayman Islands and to be deregistered in the Cayman Islands. Prior to the closing of the Business Combination, only the MLAC Class B Ordinary Shares shall carry the right to vote on any resolution of the shareholders to approve any transfer by way of continuation pursuant to the articles.	To effect the Domestication, MLAC will file an application to deregister with the Cayman Islands Registrar of Companies, together with the necessary accompanying documents, and file the Proposed Certificate of Incorporation and a certificate            of           corporate domestication with the Secretary of State of the State of Delaware, under which MLAC will be domesticated and continue as a Delaware corporation.

144

Proposal	MLAC Memorandum and Articles	Proposed Organizational  Documents
(B) Authorized and Outstanding Capital	MLAC has an authorized share capital of $50,000 divided into 445,000,000 MLAC Class A Ordinary Shares, $0.0001 par value per share, 50,000,000 MLAC Class B Ordinary Shares and 5,000,000 MLAC Preference Shares, $0.0001 par value per share.	The Proposed Organizational Documents provide that the authorized capital stock of Pubco will consist of 550,000,000 Pubco Class A Stock, 100,000,000          Pubco Class B Stock and 50,000,000 shares of preferred stock. Pubco Class A Stock will have no voting rights except as required by the DGCL, but each holder of shares of Pubco Class A Stock will be entitled to dividends and other distributions pro rata to the number of shares of Pubco Class A Stock held by them; Pubco Class B Stock will be issued with voting rights attached to them and each share will have one vote, but each holder of shares of Pubco Class B Stock will not be entitled to economic rights, including any rights to distributions.
(C) Size and Composition of the Board	The MLAC Board shall consist of not less than one person unless otherwise determined by MLAC in the general meeting.	The Proposed Organizational Documents provide that the Pubco Board will consist of one (1) or more members, each of whom shall be a natural person.
(D) Classified or Unclassified Board	The MLAC Board is made up of three classes, Class I, Class II and Class III. The number of directors in each class shall be as nearly equal as possible. The Class I directors shall stand appointed for a term expiring at MLAC’s first annual general meeting, the Class II directors shall stand appointed for a term expiring at MLAC’s second annual general meeting and the Class III directors shall stand appointed for a term expiring at MLAC’s third annual general meeting.	The Pubco Board will not be classified. The directors of Pubco hold office for a term of one (1) year and will serve until their successors are duly elected and qualified or until his or her earlier death, resignation or removal.
(E) Provisions Related to Status as a Blank Check Company	The MLAC Memorandum and Articles contain specific provisions which reflect its listing status as a SPAC. These include provisions related to, among other things, the following: MLAC Class B Ordinary Shares, redemption of Public Shares, business combination, business opportunities, termination if an initial business combination is not consummated by the end of the Combination Period and the Trust Account.	Pubco is not a blank check company, so the Proposed Organizational Documents do not include any blank check company status provision.

145

Reasons for the Adoption of the Domestication and Proposed Organizational Documents

Prior to the Closing, MLAC will effect the Domestication under Section 388 of the DGCL and Section 206 of the Cayman Act, pursuant to which MLAC will transfer by way of continuation to and become a Delaware corporation.

During the brief period of time after the Domestication and prior to the MLAC Merger, the MLAC Shareholders will hold shares of MLAC, which will be governed by an interim charter (the “MLAC Interim Charter”) and interim bylaws (the “MLAC Interim Bylaws”). The MLAC Interim Charter and MLAC Interim Bylaws will generally include the same economic and voting rights and governance structure (including a classified board of directors) as are currently provided in the MLAC Memorandum and Articles, other than any differences that exist as a matter of Delaware and Cayman Islands law, respectively, including those outlined in the “Comparison of Shareholders’ Rights”. During the brief period of time after the Domestication and prior to the MLAC Merger, MLAC does not expect to take any action other than any actions required in connection with the MLAC Merger, including that there will be no director or stockholder meeting, no distributions to MLAC stockholders and no transfers of MLAC securities.

At least two hours after the Domestication, MLAC Merger Sub will merge with and into MLAC in accordance with the applicable provisions of the DGCL and the DLLCA, with MLAC continuing as the surviving company and a wholly-owned subsidiary of Pubco. The Pubco Board believes that effecting the MLAC Merger prior to the Closing is in the best interest of Pubco because the

Domestication allows Pubco’s final structure to consist entirely of US entities, simplifying such structure and avoiding complications related to having a non-US subsidiary.

The variations between the MLAC Memorandum and Articles and the Proposed Organizational Documents are desirable for the following reasons:

• The greater number of authorized number of shares of capital stock is desirable for Pubco to have enough additional authorized shares for financing its business, for acquiring other businesses, for forming strategic partnerships and alliances and for stock dividends and stock splits and to issue upon exercise of the equity grants made under the Incentive Plan (assuming the Incentive Plan is adopted in connection with the Closing).

• The provisions on the size and composition of the Pubco Board (Sub-proposal C), an unclassified board (Sub-proposal D) are necessary to reflect the changes in terms of corporate governance as a consequence of the Business Combination. The Pubco Board believes that an unclassified board of directors in the best interest of Pubco.

• The elimination of certain provisions related to MLAC’s status as a blank check company is desirable because these provisions will serve no purpose following the Business Combination. For example, the Proposed Organizational Documents do not include the requirement to dissolve Pubco and subject to the DGCL, the Proposed Organizational Documents allow it to continue as a corporate entity with perpetual existence following consummation of the Business Combination. In addition, certain other provisions in the MLAC Memorandum and Articles require that proceeds from the MLAC IPO be held in the Trust Account until a business combination or liquidation of MLAC has occurred. These provisions cease to apply once the Business Combination is consummated and are therefore not included in the Proposed Organizational Documents.

Required Vote and Recommendation of the MLAC Board

The approval of each of the Domestication and Organizational Documents Proposals does not require the passing of a resolution under the MLAC Memorandum and Articles or Cayman Islands law. Notwithstanding this, the MLAC Board is asking MLAC Shareholders to approve the Domestication and Organizational Documents Proposals, on a non-binding advisory basis, by an ordinary resolution, being a resolution passed at the Meeting by the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). Abstentions and broker non-votes will be counted towards the quorum requirement but will not have an effect on the Domestication and Organizational Documents Proposals. The adoption of the Domestication and Organizational Documents Proposals is conditioned upon the approval of the MLAC Shareholder Approval Matters.

146

The full text of the resolutions to be passed is as follows:

“RESOLVED, as separate non-binding advisory ordinary resolutions, that the following provisions of the Amended and Restated Pubco Charter and Pubco’s Amended and Restated Bylaws, including the differences between the Amended and Restated Pubco Charter and the MLAC Memorandum and Articles be confirmed, ratified and approved:

Proposal A: the registration of MLAC will be transferred by way of continuation from the Cayman Islands to the State of Delaware.

Proposal B: the authorized capital stock of Pubco will consist of 550,000,000 Pubco Class A Stock, 100,000,000 Pubco Class B Stock and 50,000,000 shares of preferred stock.

Proposal C: the size and composition of the board of directors will be changed to one (1) or more members, each of whom shall be a natural person.

Proposal D: the Proposed Organizational Documents will provide for an unclassified Pubco Board.

Proposal E: the Proposed Organizational Documents will not include such provisions related to MLAC’s status as a blank check company, which no longer will apply upon consummation of the Business Combination, as the surviving entity, Pubco, will not be a blank check company at such time.”

THE MLAC BOARD UNANIMOUSLY RECOMMENDS THAT MLAC SHAREHOLDERS VOTE

“FOR” THE APPROVAL OF EACH OF THE DOMESTICATION AND ORGANIZATIONAL

DOCUMENTS PROPOSALS.

The existence of financial and personal interests of one or more of MLAC’s directors may result in a conflict of interest on the part of such director(s) between what they may believe is in the best interests of MLAC and MLAC Shareholders and what they may believe is best for himself, herself or themselves in determining to recommend that MLAC Shareholders vote for the Proposals. See the section entitled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and its Affiliates in the Business Combination” for a further discussion.

147

THE NASDAQ PROPOSAL

Overview

In connection with the Transactions, MLAC and Pubco intend to effect (subject to customary terms and conditions) the following issuances:

• The issuance in the Mergers, pursuant to the Business Combination Agreement, of up to 10,605,638 shares of Pubco Class A Stock and;

• The issuance, pursuant to the Company Unit Subscription Agreements, of up to 21,563,032 Pubco Class A Stock upon Closing;

• The issuance, pursuant to the Dragonfly Contribution, of 5,805,638 shares of Pubco Class A Stock and up to 5,805,638 shares of Pubco Class B Stock upon Closing;

• The issuance of up to 3,000,000 shares of Pubco Stock in connection with the Foundation Transaction;

• The reservation and issuance of up to 9,000,000 shares of Pubco Class A Stock pursuant to the Incentive Plan.

Reasons for the Approval for Purposes of Nasdaq Rule 5635

Under Nasdaq Rule 5635(a), shareholder approval is required prior to the issuance of securities in connection with the acquisition of another company if such securities are not issued in a public offering and (i) have, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding before the issuance of ordinary shares (or securities convertible into or exercisable for ordinary shares); or (ii) the number of ordinary shares to be issued is or will be equal to or in excess of 20% of the number of ordinary shares outstanding before the issuance of the share or securities.

Under Nasdaq Rule 5635(d), shareholder approval is required for a transaction other than a public offering involving the sale, issuance or potential issuance by an issuer of ordinary shares (or securities convertible into or exercisable for ordinary shares) at a price that is less than the Minimum Price which is (i) the Nasdaq official closing price immediately preceding the signing of the binding agreement; or (ii) the average Nasdaq official closing price of the common stock for the five trading days immediately preceding the signing of the binding agreement if the number of shares of common stock to be issued is or may be equal to 20% or more of the common stock, or 20% or more of the voting power, outstanding before the issuance.

Under Nasdaq Rule 5635(b), shareholder approval is required when any issuance or potential issuance will result in a “change of control” of the issuer. Although Nasdaq has not adopted any rule on what constitutes a “change of control” for purposes of Rule 5635(b), Nasdaq has previously indicated that the acquisition of, or right to acquire, by a single investor or affiliated investor group, as little as 20% of the ordinary shares (or securities convertible into or exercisable for ordinary shares) or voting power of an issuer could constitute a change of control.

Upon the consummation of the Transactions, Pubco expects to issue, in the aggregate, (i) up to an estimated 10,605,638 shares of Pubco Class A Stock in connection with the Business Combination, (ii) up to 21,563,032 shares of Pubco Class A Stock in connection with the Company Unit Subscription, (iii) up to 5,805,638 shares of Pubco Class A Stock and up to 5,805,638 shares of Pubco Class B Stock in connection with the Dragonfly Contribution, (iv) up to 3,000,000 shares of Pubco Class A Stock in connection with the Foundation Transaction and (v)  up to 9,000,000 additional shares of Pubco Class A Stock that will, upon Closing, be reserved for issuance pursuant to the Incentive Plan. For further details, see “The Business Combination Proposal — The Business Combination Agreement,” “The Business Combination Proposal — Other Transaction Agreements — The Company Unit Subscription Agreements” and “Executive and Director Compensation Material Terms of the Incentive Plan.”

Accordingly, the aggregate number of shares of Pubco Class A Stock and Pubco Class B Stock that Pubco will issue in connection with the Business Combination will, in the aggregate, exceed 20% of both the voting power and the number of MLAC Ordinary Shares outstanding before such issuance and will result in a change of control of MLAC. For these reasons, MLAC is seeking the approval of MLAC Shareholders for the issuance of the shares of Pubco Class A Stock and Pubco Class B Stock in

148

connection with the Business Combination pursuant to Nasdaq Rules 5635(a) and (b). For further details, see “The Business Combination Proposal — The Business Combination Agreement” and “The Business Combination Proposal — Other Transaction Agreements — The Company Unit Subscription Agreements.”

In addition, in the future, Pubco may issue additional shares of Pubco Class A Stock reserved for issuance under the Incentive Plan. For further details, see “The Business Combination Proposal — The Business Combination Agreement,” “The Business Combination — Other Transaction Agreements — The Company Unit Subscription Agreements” and “Executive and Director Compensation — Summary of the Material Terms of the Incentive Plan.”

Effect of the Proposal on MLAC Shareholders

In the event that the Nasdaq Proposal is approved by MLAC Shareholders, but the Business Combination Agreement is terminated (without the Business Combination being consummated) prior to the issuance of shares of Pubco Class A Stock and Pubco Class B Stock pursuant to the Business Combination Agreement, Contribution Agreement, Company Unit Subscription Agreements and Token Sale Agreement, Pubco will not issue such shares of Pubco Class A Stock and Pubco Class B Stock.

Required Vote and Recommendation of the MLAC Board

The approval of the Nasdaq Proposal does not require the passing of a resolution under the MLAC Memorandum and Articles or Cayman Islands law. Notwithstanding this, the MLAC Board is asking MLAC Shareholders to approve the Nasdaq Proposal by an ordinary resolution, being a resolution passed at the Meeting by the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). Abstentions and broker non-votes will be counted towards the quorum requirement but will not have an effect on the Nasdaq Proposal. The adoption of the Nasdaq Proposal is conditioned upon the approval of the MLAC Shareholder Approval Matters.

The full text of the resolution to be passed is as follows:

“RESOLVED, as an ordinary resolution, that for the purposes of complying with the applicable provisions of Nasdaq Rules 5635(a) and 5635(b), the issuance of (i) up to 10,605,638 shares of Class A common stock of Pubco (“Pubco Class A Stock”) in connection with the Business Combination, (ii) up to 21,563,032 shares of Pubco Class A Stock in connection with the Company Unit Subscription, (iii) up to 5,805,638 shares of Pubco Class A Stock and up to 5,805,638 shares of Class B common stock of Pubco (“Pubco Class B Stock”) in connection with the Dragonfly Contribution, (iv) up to 3,000,000 shares of Pubco Class A Stock in connection with the Foundation Transaction and (v) up to 9,000,000 shares of Pubco Class A Stock that will be reserved for issuance upon the Closing pursuant to the Avalanche Treasury Corporation 2026 Omnibus Incentive Plan, to be adopted prior to Closing, as amended from time to time (the “Incentive Plan”), be approved.”

THE MLAC BOARD UNANIMOUSLY RECOMMENDS THAT MLAC SHAREHOLDERS VOTE

“FOR” THE APPROVAL OF THE NASDAQ PROPOSAL.

The existence of financial and personal interests of one or more of MLAC’s directors may result in a conflict of interest on the part of such director(s) between what they may believe is in the best interests of MLAC and MLAC Shareholders and what they may believe is best for himself, herself or themselves in determining to recommend that MLAC Shareholders vote for the Proposals. See the section entitled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and its Affiliates in the Business Combination” for a further discussion.

149

THE DIRECTOR ELECTION PROPOSAL

The MLAC Board is divided into three classes, with only one class of directors being elected in each year, and with each class (except for those directors appointed prior to its first annual meeting of shareholders) serving a three-year term: Class I, with a term expiring at the first annual general meeting — Jeffrey T. Lager and Michael Marquez; Class II, with a term expiring at the second annual general meeting — Jaime W. Vieser and Douglas Horlick; and Class III, with a term expiring at the third annual general meeting — Paul Grinberg. For purposes of the MLAC Memorandum and Articles, this Meeting is serving as MLAC’s first annual general meeting of shareholders. The terms of MLAC’s current Class I directors will expire at MLAC’s first annual meeting. The MLAC board has therefore nominated Jeffrey T. Lager and Michael Marquez for election as MLAC Class I directors to the MLAC Board to serve until the third succeeding annual general meeting or until a successor is elected and qualified or their earlier resignation or removal.

In connection with the closing of the Business Combination, we anticipate that Mr. Lager, Mr. Marquez, Mr. Vieser, Mr. Horlick and Mr. Grinberg will submit their resignations from their positions as members of MLAC Board and of any committee thereof (conditioned upon and effective as of the consummation of the Business Combination) and Mr. Grinberg will be appointed as director to the Pubco Board, effective immediately after the consummation of the Business Combination. See the section entitled “Management of Pubco Following the Business Combination.”

The two directors who are elected as Class I directors will be elected to serve on the MLAC Board until MLAC’s annual meeting in 2029, or until their earlier resignation, removal or death. The election of these directors is not contingent upon approval of the Business Combination. The Director Election Proposal is being presented to shareholders so that in the event the Business Combination is not consummated, MLAC’s Class I directors may be re-elected. If the Business Combination is consummated, MLAC will become a wholly-owned subsidiary of Pubco, upon which all members of the board of directors of MLAC will resign.

Required Vote and Recommendation of the MLAC Board

The approval of the Director Election Proposal does not require the passing of a resolution under the MLAC Memorandum and Articles or Cayman Islands law. Notwithstanding this, the MLAC Board is asking MLAC Shareholders to approve the Director Election Proposal by an ordinary resolution, being a resolution passed at the Meeting by the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). Abstentions and broker non-votes will be counted towards the quorum requirement but will not have an effect on the Director Election Proposal. The adoption of the Director Election Proposal is not conditioned on the approval of any other Proposal.

THE MLAC BOARD UNANIMOUSLY RECOMMENDS THAT MLAC SHAREHOLDERS VOTE

“FOR” THE APPROVAL OF THE DIRECTOR ELECTION PROPOSAL.

150

THE ADJOURNMENT PROPOSAL

Overview

The Adjournment Proposal, if adopted, will allow the MLAC Board or the Chairman of the Meeting to adjourn the Meeting to a later date or dates, including to permit further solicitation of proxies. The Adjournment Proposal will be presented to MLAC Shareholders in the event that it is determined by MLAC that additional time is necessary or appropriate to complete the Business Combination or for any other reason. In no event will the MLAC Board adjourn the Meeting or consummate the Business Combination beyond the date by which it may properly do so under the MLAC Memorandum and Articles and Cayman Islands law.

Consequences if the Adjournment Proposal is Not Approved

If the Adjournment Proposal is presented to the Meeting and is not approved by MLAC Shareholders, the MLAC Board or the Chairman of the Meeting will not have the power, under the MLAC Memorandum and Articles, to adjourn the Meeting to a later date in the event it is determined by MLAC that additional time is necessary or appropriate to complete the Business Combination or for any other reason. As a result, a new extraordinary general meeting would need to be called before the MLAC Shareholders could vote on Proposals again.

Required Vote and Recommendation of the MLAC Board

The approval of the Adjournment Proposal will require an ordinary resolution, being a resolution passed at the Meeting by the affirmative vote of a simple majority of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Meeting (assuming the presence of a quorum). Abstentions and broker non-votes will be counted towards the quorum requirement but will not have an effect on the Adjournment Proposal. The adoption of the Adjournment Proposal is not conditioned on the approval of any other Proposal.

The full text of the resolution to be passed is as follows:

“RESOLVED, as an ordinary resolution, that the adjournment of the Meeting to a later date or dates to be determined by the Chairman of the Meeting, if necessary or desirable, (i) to permit further solicitation and vote of proxies in the event that, based upon the tabulated vote at the time of the Meeting, there are insufficient votes for, or otherwise in connection with, the approval of one or more proposals at the Meeting or (ii) if the Board determines before the Meeting or the Chairman of the Meeting determines at the Meeting that it is not necessary or no longer desirable to proceed with the proposals, be approved in all respects.”

THE MLAC BOARD UNANIMOUSLY RECOMMENDS THAT MLAC SHAREHOLDERS VOTE

“FOR” THE APPROVAL OF THE ADJOURNMENT PROPOSAL.

The existence of financial and personal interests of one or more of MLAC’s directors may result in a conflict of interest on the part of such director(s) between what they may believe is in the best interests of MLAC and MLAC Shareholders and what they may believe is best for himself, herself or themselves in determining to recommend that MLAC Shareholders vote for the Proposals. See the section entitled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and its Affiliates in the Business Combination” for a further discussion.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following description addresses the U.S. federal income tax considerations generally applicable to (i) U.S. Holders and Non-U.S. Holders (as defined below) that elect to have their Public Shares redeemed for cash if the Business Combination is completed, (ii) U.S. Holders of MLAC Rights regarding the conversion of MLAC Rights to Pubco Class A Stock in connection with the Business Combination, (iii) U.S. Holders and Non-U.S. Holders that participate in the Domestication and MLAC Merger, and (iv) Non-U.S. Holders of owning and disposing of shares of Pubco Class A Stock after the Business Combination. It does not address U.S. federal income tax consequences of the Domestication or Business Combination on other MLAC securities. The following description is the opinion of EGS. The information set forth in this section is based on the Code, its legislative history, final, temporary and proposed treasury regulations promulgated thereunder (“Treasury Regulations”), published rulings and court decisions, all as currently in effect. These authorities are subject to change or differing interpretations, possibly on a retroactive basis.

For purposes of this description, a “U.S. Holder” means a beneficial owner of Public Shares or, where the context so provides, MLAC Rights that is for U.S. federal income tax purposes:

• an individual citizen or resident of the United States;

• a corporation (or other entity treated as a corporation) that is created or organized (or treated as created or organized) in or under the laws of the United States, any state thereof or the District of Columbia;

• an estate whose income is includible in gross income for U.S. federal income tax purposes regardless of its source; or

• a trust if (i) a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized to control all substantial decisions of the trust, or (ii) it has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person.

A “Non-U.S. Holder” means a beneficial owner of Public Shares that, for U.S. federal income tax purposes, is not a U.S. Holder or a partnership or other entity classified as a partnership for U.S. federal income tax purposes.

This description does not address all aspects of U.S. federal income taxation that may be relevant to any particular holder based on such holder’s individual circumstances. In particular, this description considers only holders that hold Public Shares or MLAC Rights as capital assets within the meaning of Section 1221 of the Code. This description does not address the alternative minimum tax, the Medicare tax on net investment income, or the U.S. federal income tax consequences to holders that are subject to special rules, including:

• financial institutions or financial services entities;

• broker-dealers;

• persons that are subject to the mark-to-market accounting rules under Section 475 of the Code;

• tax-exempt entities;

• governments or agencies or instrumentalities thereof;

• insurance companies;

• regulated investment companies;

• real estate investment trusts;

• specified expatriates or former long-term residents of the United States;

152

• persons that acquired Public Shares pursuant to an exercise of employee options, in connection with employee incentive plans or otherwise as compensation;

• persons that hold Public Shares as part of a straddle, constructive sale, hedging, redemption or other integrated transaction;

• persons whose functional currency is not the U.S. dollar;

• controlled foreign corporations;

• passive foreign investment companies;

• partnerships (or other entities classified as partnership for U.S. federal income tax purposes) or partners in such partnerships or entities classified for U.S. federal income tax purposes as a “disregarded entity”;

• persons required to accelerate the recognition of any item of gross income with respect to Public Shares as a result of such income being recognized on an applicable financial statement;

• persons who actually or constructively own 5% or more of MLAC’s shares or Pubco’s shares by vote or value (except as specifically provided below); or

• the Sponsor or its affiliates, or MLAC’s officers and directors.

This description does not address any tax laws other than the U.S. federal income tax law, such as gift or estate tax laws, state, local or non-U.S. tax laws or, except as described herein, any tax reporting obligations of a holder of Public Shares or MLAC Rights. Additionally, this description does not address the tax treatment of partnerships or other pass-through entities or entities classified for U.S. federal income tax purposes as a “disregarded entity” or persons who hold Public Shares or MLAC Rights through such entities. If a partnership (or other entity classified as a partnership or treated as a disregarded entity for U.S. federal income tax purposes) is the beneficial owner of Public Shares or MLAC Rights, the U.S. federal income tax treatment of a partner in the partnership or owner of the disregarded entity will generally depend on the status of the partner or owner and the activities of the partnership or disregarded entity. This description also assumes that any distribution made (or deemed made) on Public Shares and any consideration received (or deemed received) by a holder in consideration for the sale or other disposition of Public Shares or MLAC Rights is made in U.S. dollars.

THE U.S. FEDERAL INCOME TAX TREATMENT OF THE BENEFICIAL OWNERS OF PUBLIC SHARES OR MLAC RIGHTS MAY BE AFFECTED BY MATTERS NOT DESCRIBED HEREIN AND DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF COMPLEX PROVISIONS OF U.S. FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR AUTHORITY MAY BE AVAILABLE. MLAC URGES BENEFICIAL OWNERS OF PUBLIC SHARES OR MLAC RIGHTS WHO EXERCISE THEIR CONVERSION RIGHTS OR WHO CHOOSE TO PARTICIPATE IN THE DOMESTICATION TO CONSULT THEIR TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO SUCH HOLDER OF THE DOMESTICATION AND OWNING AND DISPOSING OF PUBLIC SHARES AS A RESULT OF ITS PARTICULAR CIRCUMSTANCES, INCLUDING THE U.S. FEDERAL, STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX CONSEQUENCES THEREOF.

U.S. Holders

Tax Consequences of the Domestication to U.S. Holders of Public Shares

The Domestication will qualify as a reorganization within the meaning of Section 368(a)(1)(F) of the Code for U.S. federal income tax purposes. Consequently, except as otherwise provided below in the section entitled “— PFIC Considerations,” and “— Effects of Section 367 to U.S. Holders of Public Shares,” a U.S. Holder of Public Shares will not recognize gain or loss upon the exchange of its Public Shares solely for MLAC common stock pursuant to the Domestication. A U.S. Holder’s aggregate tax basis in the MLAC common stock received in connection with the Domestication will generally be the same as its aggregate tax basis in the

153

Public Shares surrendered in the transaction. In addition, the holding period of MLAC common stock received in the Domestication generally should include the holding period of Public Shares surrendered in the Domestication.

Tax Consequences of the Conversion of MLAC Rights to Pubco Class A Stock to U.S. Holders of MLAC Rights

A U.S. Holder should not recognize gain or loss upon the automatic conversion of the MLAC Rights to Pubco Class A Stock. If this treatment is respected, and except as otherwise provided below in the section entitled “— PFIC Considerations,” (i) the tax basis of the Pubco Class A Stock acquired by a U.S. Holder pursuant to the automatic conversion of the MLAC Rights to Pubco Class A Stock should be equal to the U.S. Holder’s tax basis in the relevant MLAC Rights with respect to which the Pubco Class A Stock were issued and (ii) the holding period of such Pubco Class A Stock should begin on the day after the conversion of the MLAC Rights into such Pubco Class A Stock.

Nevertheless, because no direct authority explicitly addresses the treatment of the MLAC Rights for U.S. federal income tax purposes, the treatment is not entirely clear. If the tax treatment is not as described above, then holders of MLAC Rights would recognize taxable gain or loss equal to the difference between the fair market value of the Pubco Class A Stock received and the tax basis of the MLAC Rights converted in respect of such Pubco Class A Stock. Accordingly, U.S. Holders of MLAC Rights should consult their tax advisors regarding the tax consequences of the automatic conversion of the MLAC Rights to Pubco Class A Stock.

Tax Consequences of the Business Combination to U.S. Holders of MLAC Common Stock after the Domestication

The Business Combination will qualify as an exchange described in Section 351(a) of the Code. However, there can be no assurance that the U.S. Internal Revenue Service (the “IRS”) will not successfully challenge this position, and if so then the exchange of MLAC common stock for Pubco Class A Common Stock will be a taxable exchange, and the tax consequences described herein will be materially different from those described below. The remainder of this discussion assumes that the transactions described above qualify as an exchange described in Section 351 of the Code. Assuming such qualification, a U.S. Holder that receives Pubco Class A Common Stock in exchange for MLAC common stock in the Business Combination generally should not recognize any gain or loss on such exchange. In such case, the aggregate adjusted tax basis of the Pubco Class A Common Stock received in the Business Combination by a U.S. Holder should be equal to the adjusted tax basis of the MLAC common stock exchange there for. The holding period of the Pubco Class A Common Stock should include the holding period during which the MLAC common stock exchanged therefor were held by such U.S. Holder (which, as discussed above, should include the holding period of any Public Shares surrendered in the Domestication).

PFIC Considerations

Even if the Domestication qualifies as a reorganization within the meaning of Section 368(a) of the Code, the Domestication may still be a taxable event to U.S. Holders of Public Shares under the PFIC provisions of the Code, to the extent that Section 1291(f) of the Code applies, as described below.

Effect of PFIC Rules on the Domestication

Even if the Domestication qualifies as a reorganization for U.S. federal income tax purposes under Section 368(a) of the Code, Section 1291(f) of the Code requires that, to the extent provided in regulations, a U.S. person that disposes of stock of a PFIC must recognize gain notwithstanding any other provision of the Code. No final Treasury regulations are in effect under Section 1291(f). Proposed Treasury Regulations under Section 1291(f) were promulgated in 1992, with a retroactive effective date once they become finalized. If finalized in their present form, those regulations would require taxable gain recognition by a U.S. Holder with respect to its exchange of Public Shares for MLAC common stock in the Domestication if MLAC were classified as a PFIC at any time during such U.S. Holder’s holding period in the Public Shares. Any such gain would be treated as an “excess distribution” made in the year of the Domestication and subject to the special tax and interest charge rules described below under “Definition and General Taxation of a PFIC.” It is difficult to predict whether, in what form, and with what effective date, final Treasury Regulations under Section 1291(f) of the Code may be adopted and how any such Treasury Regulations would apply. Therefore, U.S. Holders that have not timely made certain elections discussed further below may, pursuant to the proposed Treasury Regulations, be subject to taxation under the PFIC rules on the Domestication with respect to their Public Shares in the manner set forth below. The proposed Treasury Regulations under Section 1291(f) should not apply to an Electing Shareholder (as defined below) with respect to its Public Shares for which a timely QEF election, QEF election with a purging election, or MTM election is made, as each such election is described below.

154

Definition and General Taxation of a PFIC

A non-U.S. corporation will be a PFIC if either (a) at least 75% of its gross income in a taxable year, including its pro rata share of the gross income of any corporation in which it owns or is considered to own at least 25% of the shares by value, is passive income (the “gross income test”) or (b) at least 50% of its assets in a taxable year, ordinarily determined based on fair market value and averaged quarterly over the year, including its pro rata share of the assets of any corporation in which it owns or is considered to own at least 25% of the shares by value, are held for the production of, or produce, passive income (the “asset test”). Passive income generally includes dividends, interest, rents and royalties (other than certain rents or royalties derived from the active conduct of a trade or business) and gains from the disposition of passive assets. The determination of whether a foreign corporation is a PFIC is made annually. Based upon the composition of its income and assets, MLAC believes that it would likely be considered a PFIC for its current taxable year.

If MLAC is determined to be a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder of Public Shares and the U.S. Holder did not make either (a) a timely “qualified election fund” (QEF) election for MLAC’s first taxable year as a PFIC in which the U.S. Holder held (or was deemed to hold) Public Shares, (b) a QEF election along with a “purging election,” or (c) a “mark-to-market” (MTM) election, all of which are described further below, such U.S. Holder generally will be subject to special rules with respect to any gain recognized by the U.S. Holder on the sale or other disposition of its Public Shares and any “excess distribution” made to the U.S. Holder. Excess distributions are generally any distributions to such U.S. Holder during a taxable year of the U.S. Holder that are greater than 125% of the average annual distributions received by such U.S. Holder in respect of the Public Shares during the three preceding taxable years of such U.S. Holder or, if shorter, such U.S. Holder’s holding period for the Public Shares.

Under these rules, the U.S. Holder’s gain or excess distribution will be allocated ratably over the U.S. Holder’s holding period for the Public Shares. The amount allocated to the U.S. Holder’s taxable year in which the U.S. Holder recognized the gain or received the excess distribution, or to the period in the U.S. Holder’s holding period before the first day of MLAC’s first taxable year in which it qualified as a PFIC, will be taxed as ordinary income. The amount allocated to other taxable years (or portions thereof) of the U.S. Holder and included in its holding period will be taxed at the highest tax rate in effect for that year and applicable to the U.S. Holder. The interest charge generally applicable to underpayments of tax will be imposed in respect of the tax attributable to each such other taxable year of the U.S. Holder.

In general, if MLAC is determined to be a PFIC, a U.S. Holder may avoid the tax consequences described above with respect to its Public Shares by making a timely QEF election (or a QEF election along with a purging election), or an MTM election, all as described below.

Impact of PFIC Rules on Certain U.S. Holders

The impact of the PFIC rules on a U.S. Holder of Public Shares will depend on whether the U.S. Holder has made a timely and effective election to treat MLAC as a QEF, under Section 1295 of the Code, for MLAC’s first taxable year as a PFIC in which the U.S. Holder held (or was deemed to hold) Public Shares, the U.S. Holder made a QEF election along with a “purging election,” or if the U.S. Holder made an MTM election, all as described below. A U.S. Holder of a PFIC that made either a timely and effective QEF election, a QEF election along with a purging election, or an MTM election is hereinafter referred to as an “Electing Shareholder.”

A U.S. Holder’s ability to make a QEF election with respect to its Public Shares is contingent upon, among other things, the provision by MLAC of certain information that would enable the U.S. Holder to make and maintain a QEF election. MLAC will endeavor to provide to a U.S. Holder such information as the IRS may require, including a PFIC annual information statement, in order to enable the U.S. Holder to make and maintain a QEF election, but there can be no assurance that MLAC will timely provide such information that is required to make and maintain the QEF election.

As indicated above, if a U.S. Holder of Public Shares has not made a timely and effective QEF election with respect to MLAC’s first taxable year as a PFIC in which the U.S. Holder held (or was deemed to hold) Public Shares, such U.S. Holder generally may nonetheless qualify as an Electing Shareholder by filing on a timely filed U.S. income tax return (including extensions) a QEF election and a purging election to recognize under the rules of Section 1291 of the Code any gain that it would otherwise recognize if the U.S. Holder sold its Public Shares for their fair market value on the “qualification date.” The qualification date is the first day of MLAC’s tax year in which MLAC qualifies as a QEF with respect to such U.S. Holder. The purging election can only be made if such U.S.

155

Holder held Public Shares on the qualification date. The gain recognized by the purging election will be subject to the special tax and interest charge rules treating the gain as an excess distribution, as described above. As a result of the purging election, the U.S. Holder will increase the adjusted tax basis in its Public Shares by the amount of the gain recognized and will also have a new holding period in the Public Shares for purposes of the PFIC rules.

Alternatively, if a U.S. Holder, at the close of its taxable year, owns shares in a PFIC that are treated as marketable shares, the U.S. Holder may make an MTM election with respect to such shares for such taxable year. If the U.S. Holder makes a valid MTM election for the first taxable year of the U.S. Holder in which the U.S. Holder holds (or is deemed to hold) Public Shares and for which MLAC is determined to be a PFIC, such holder will not be subject to the PFIC rules described above in respect to its Public Shares. Instead, the U.S. Holder will include as ordinary income each year the excess, if any, of the fair market value of its Public Shares at the end of its taxable year over the adjusted basis in its Public Shares. The U.S. Holder also will be allowed to take an ordinary loss in respect of the excess, if any, of the adjusted basis of its Public Shares over the fair market value of its Public Shares at the end of its taxable year (but only to the extent of the net amount of previously included income as a result of the mark-to-market election). The U.S. Holder’s basis in its Public Shares will be adjusted to reflect any such income or loss amounts and any further gain recognized on a sale or other taxable disposition of the Public Shares will be treated as ordinary income. The MTM election is available only for shares that are regularly traded on a national securities exchange that is registered with the Securities and Exchange Commission, or on a foreign exchange or market that the IRS determines has rules sufficient to ensure that the market price represents a legitimate and sound fair market value. U.S. Holders should consult their own tax advisers regarding the availability and tax consequences of an MTM election in respect to Public Shares under their particular circumstances.

The rules dealing with PFICs and with the timely QEF election, the QEF election with a purging election, and the MTM election are very complex and are affected by various factors in addition to those described above. Accordingly, a U.S. Holder of Public Shares or MLAC Rights should consult its own tax advisor concerning the application of the PFIC rules to such securities under such holder’s particular circumstances.

Effects of Section 367 to U.S. Holders of Public Shares

Section 367 of the Code applies to certain non-recognition transactions involving foreign corporations, including a domestication of a foreign corporation in a reorganization within the meaning of Section 368(a) of the Code. Section 367 of the Code imposes income tax on certain United States persons in connection with transactions that would otherwise be tax-free. Section 367(b) of the Code will generally apply to U.S. Holders of Public Shares on the date of the Domestication.

A. U.S. Holders Whose Public Shares Have a Fair Market Value of $50,000 or More and Who Own 10% or More of the Voting Power or Value of MLAC

A U.S. Holder who, on the date of the Domestication beneficially owns (directly, indirectly or constructively) 10% or more of the total combined voting power or value of MLAC (a “10% U.S. Shareholder”) must include in income as a dividend the “all earnings and profits amount” (as defined in Treasury Regulation Section 1.367(b)-2(d)) attributable to the Public Shares it directly owns. A U.S. Holder’s ownership of MLAC Rights and MLAC Units will be taken into account in determining whether such U.S. Holder owns 10% or more of the total combined voting power or value of MLAC. Complex attribution rules apply in determining whether a U.S. Holder owns 10% or more of the total combined voting power or value of MLAC and all U.S. Holders are urged to consult their tax advisors with respect to these attribution rules.

A 10% U.S. Shareholder’s “all earnings and profits amount” with respect to its Public Shares is the net positive earnings and profits of MLAC attributable to its shares (as determined under Treasury Regulation Section 1.367(b)-2) but without regard to any gain that would be realized on a sale or exchange of such shares.

B. U.S. Holders Whose Public Shares Have a Fair Market Value of $50,000 or More But Who Own Less Than 10% of the Voting Power and Value of MLAC

A U.S. Holder who, on the date of the Domestication, beneficially owns (directly, indirectly or constructively) Public Shares with a fair market value of $50,000 or more but owns less than 10% of the total combined voting power and value of MLAC will recognize gain (but not loss) with respect to the Domestication unless such U.S. Holder elects to recognize the “all earnings and profits” amount attributable to such holder as described below.

156

Unless such a U.S. Holder makes the “all earnings and profits” election as described below, such holder generally must recognize gain (but not loss) with respect to MLAC common stock received in the Domestication in an amount equal to the excess of the fair market value of MLAC common stock received over the U.S. Holder’s adjusted tax basis in the Public Shares deemed surrendered in the Domestication.

As an alternative to recognizing any gain as described in the preceding paragraph, such a U.S. Holder may elect to include in income as a deemed dividend the “all earnings and profits amount” attributable to its Public Shares under Section 367(b) of the Code. There are, however, strict conditions for making this election. This election must comply with applicable Treasury Regulations and generally must include, among other things:

(i) a statement that the Domestication is a Section 367(b) exchange;

(ii) a complete description of the Domestication;

(iii) a description of any stock, securities or other consideration transferred or received in the Domestication;

(iv) a statement describing the amounts required to be taken into account for U.S. federal income tax purposes;

(v) a statement that the U.S. Holder is making the election and that includes (A) a copy of the information that the U.S. Holder received from MLAC establishing and substantiating the “all earnings and profits amount” with respect to the U.S. Holder’s Public Shares, and (B) a representation that the U.S. Holder has notified MLAC that the U.S. Holder is making the election; and

(vi) certain other information required to be furnished with the U.S. Holder’s tax return or otherwise furnished pursuant to the Code or the Treasury Regulations thereunder.

In addition, the election must be attached by an electing U.S. Holder to such holder’s timely filed U.S. federal income tax return for the taxable year in which the Domestication occurs, and the U.S. Holder must send notice of making the election to MLAC no later than the date such tax return is filed. In connection with this election, MLAC may in its discretion provide each U.S. Holder eligible to make such an election with information regarding MLAC’s earnings and profits upon request.

MLAC does not expect to have significant, if any, cumulative earnings and profits through the date of the Domestication and if that proves to be the case, U.S. Holders who make this election are not expected to have a significant income inclusion under Section 367(b) of the Code, provided that the U.S. Holder properly executes the election and complies with the applicable notice requirements. However, as noted above, if it were determined that MLAC had positive earnings and profits through the date of the Domestication, a U.S. Holder that makes the election described herein could have an all earnings and profits amount with respect to its Public Shares, and thus could be required to include that amount in income as a deemed dividend under applicable Treasury Regulations as a result of the Domestication.

U.S. HOLDERS ARE STRONGLY URGED TO CONSULT A TAX ADVISOR REGARDING THE CONSEQUENCES OF MAKING AN ELECTION AND THE APPROPRIATE FILING REQUIREMENTS WITH RESPECT TO AN ELECTION.

C. U.S. Holders that Own Public Shares with a Fair Market Value of Less Than $50,000

A U.S. Holder who, on the date of the Domestication, beneficially owns (directly, indirectly, or constructively) Public Shares with a fair market value less than $50,000 should not be required to recognize any gain or loss under Section 367 of the Code in connection with the Domestication and generally should not be required to include any part of the “all earnings and profits amount” in income.

157

All U.S. Holders of Public Shares are urged to consult their tax advisors with respect to the effect of Section 367 of the Code to their particular circumstances.

Tax Consequences to U.S. Holders That Elect to Have Their Public Shares Redeemed for Cash

Subject to the PFIC rules and the Section 367 considerations described above, in the event that a U.S. Holder of Public Shares exercises such holder’s right to have such holder’s Public Shares redeemed pursuant to the redemption provisions described herein, the treatment of the transaction for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of such Public Shares pursuant to Section 302 of the Code or whether the U.S. Holder will be treated as receiving a corporate distribution within the meaning of Section 301 of the Code. Whether that redemption qualifies for sale treatment will depend largely on the total number of shares of Public Shares treated as held by the U.S. Holder (including any Public Shares constructively owned by the U.S. Holder as a result of, among other things, owning MLAC Rights) relative to all of shares of Public Shares both before and after the redemption. The redemption of Public Shares generally will be treated as a sale of the shares (rather than as a corporate distribution) if the redemption is “substantially disproportionate” with respect to the U.S. Holder, results in a “complete termination” of the U.S. Holder’s interest in MLAC or is “not essentially equivalent to a dividend” with respect to the U.S. Holder. These tests are explained more fully below.

In determining whether any of the foregoing tests are satisfied, a U.S. Holder takes into account not only stock actually owned by the U.S. Holder, but also stock that are constructively owned by such U.S. Holder. A U.S. Holder may constructively own, in addition to stock owned directly, stock owned by certain related individuals and entities in which the U.S. Holder has an interest or that have an interest in such U.S. Holder, as well as any stock the U.S. Holder has a right to acquire by exercise of an option. In order to meet the substantially disproportionate test, the percentage of MLAC’s outstanding voting stock actually and constructively owned by the U.S. Holder immediately following the redemption of Public Shares must, among other requirements, be less than 80% of the percentage of MLAC’s outstanding voting stock actually and constructively owned by the U.S. Holder immediately before the redemption. There will be a complete termination of a U.S. Holder’s interest if either all the Public Shares actually and constructively owned by the U.S. Holder are redeemed or all the Public Shares actually owned by the U.S. Holder are redeemed and the U.S. Holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of stock owned by certain family members and the U.S. Holder does not constructively own any other stock. The redemption of the Public Shares will not be essentially equivalent to a dividend if a U.S. Holder’s redemption results in a “meaningful reduction” of the U.S. Holder’s proportionate interest in MLAC. Whether the redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in MLAC will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.” A U.S. Holder should consult with its own tax advisors as to the tax consequences of redemption.

If the redemption qualifies as a sale of stock by the U.S. Holder under Section 302 of the Code, the U.S. Holder generally will be required to recognize gain or loss in an amount equal to the difference, if any, between the amount of cash received and the U.S. Holder’s adjusted tax basis in the Public Shares redeemed. Such gain or loss should be treated as capital gain or loss if such shares were held as a capital asset on the date of the redemption. A U.S. Holder’s tax basis in such holder’s shares of Public Shares generally will equal the cost of such shares. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder’s holding period for the shares so disposed of exceeds one year. Long-term capital gains recognized by non-corporate U.S. Holders generally will be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.

If the redemption does not qualify as a sale of stock under Section 302 of the Code, then the U.S. Holder will be treated as receiving a corporate distribution. Such distribution generally will constitute a dividend for U.S. federal income tax purposes to the extent paid from current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. Holder’s adjusted tax basis in such U.S. Holder’s Public Shares. Any remaining excess will be treated as gain realized on the sale or other disposition of the Public Shares. Special rules apply to dividends received by U.S. Holders that are taxable corporations. After the application of the foregoing rules, any remaining tax basis of the U.S. Holder in the redeemed Public Shares will be added to the U.S. Holder’s adjusted tax basis in its remaining Public Shares, or, to the basis of Public Shares constructively owned by such holder if the stock actually owned by the holder is completely redeemed.

Non-U.S. Holders

Tax Consequences of the Domestication and MLAC Merger to Non-U.S. Holders

Neither the Domestication nor the MLAC Merger is expected to result in any U.S. federal income tax consequences to a Non-U.S. Holder, provided that (i) the Domestication qualifies as a reorganization within the meaning of Section 368(a)(1)(F) of the Code, (ii) the Business Combination qualifies as an exchange described in Section 351(a) of the Code, and (iii) such Non-U.S. Holder does not hold the Public Shares in connection with a conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment of such Non-U.S. Holder), nor is such Non-U.S. Holder an individual who is physically present in the United States for at least 183 days during its taxable year in which the Domestication and the MLAC Merger occur and meets certain other requirements.

Tax Consequences for Non-U.S. Holders of Owning and Disposing of Pubco Class A Common Stock

Distributions on Pubco Class A Common Stock

Distributions of cash or property to a Non-U.S. Holder in respect of Pubco Class A Common Stock will constitute dividends for U.S. federal income tax purposes to the extent paid from Pubco’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds Pubco’s current and accumulated earnings and profits, the excess will be treated first as a tax-free return of capital to the extent of the Non-U.S. Holder’s adjusted tax basis in Pubco Class A Common Stock. Any remaining excess will be treated as capital gain and will be treated as described below under “— Gain on Disposition of Pubco Class A Common Stock.”

Dividends paid to a Non-U.S. Holder of Pubco Class A Common Stock generally will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty, if the Non-U.S. Holder provides proper certification of its eligibility for such lower rate. However, dividends that are effectively connected with the conduct of a trade or business by the Non-U.S. Holder within the United States (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment of the Non-U.S. Holder) are not subject to such withholding tax, provided certain certification and disclosure requirements are satisfied. Instead, such dividends are subject to United States federal income tax on a net income basis in the same manner as if the Non-U.S. Holder were a United States person as defined under the Code. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

A Non-U.S. Holder of Pubco Class A Common Stock who wishes to claim the benefit of an applicable treaty rate and avoid backup withholding, for dividends will be required (a) to complete the applicable IRS Form W-8 and certify under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (b) if Pubco Class A Common Stock are held through certain foreign intermediaries, to satisfy the relevant certification requirements of applicable United States Treasury regulations. Special certification and other requirements apply to certain Non-U.S. Holders that are pass-through entities rather than corporations or individuals.

A Non-U.S. Holder of Pubco Class A Common Stock eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim or refund with the IRS. Non-U.S. Holders are urged to consult their own tax advisors regarding their entitlement to the benefits under any applicable income tax treaty.

Gain on Disposition of Pubco Class A Common Stock

Subject to the description of backup withholding below, any gain realized by a Non-U.S. Holder on the taxable disposition of Pubco Class A Common Stock generally will not be subject to U.S. federal income tax unless:

• the gain is effectively connected with a trade or business of the Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment of the Non-U.S. Holder);

• the Non-U.S. Holder is an individual who is present in the United States for a period or periods aggregating 183 days or more in the taxable year of the disposition, and certain other conditions are met; or

159

• Pubco is or has been a “United States real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of the five year period ending on the date of disposition or the Non-U.S. Holder’s holding period for such securities disposed of, and, generally, in the case where shares of Pubco Class A Common Stock are regularly traded on an established securities market, the Non-U.S. Holder has owned, or is deemed to have owned, more than 5% of such Shares, as applicable, at any time during the shorter of the five year period ending on the date of disposition or the Non-U.S. Holder’s holding period for the Shares disposed of. There can be no assurance that shares of Pubco Class A Common Stock will be treated as regularly traded on an established securities market for this purpose.

An individual Non-U.S. Holder described in the first bullet point immediately above will be subject to tax on the net gain derived from the sale under regular graduated U.S. federal income tax rates. An individual Non-U.S. Holder described in the second bullet point immediately above will be subject to a flat 30% tax on the gain derived from the sale, which may be offset by United States source capital losses, even though the individual is not considered a resident of the United States, provided that the individual has timely filed U.S. federal income tax returns with respect to such losses. If a Non-U.S. Holder that is a foreign corporation falls under the first bullet point immediately above, it will be subject to tax on its net gain in the same manner as if it were a United States person as defined under the Code and, in addition, may be subject to the branch profits tax equal to 30% (or such lower rate as may be specified by an applicable income tax treaty) of its effectively connected earnings and profits, subject to adjustments.

Pubco does not believe it is and does not anticipate becoming a “United States real property holding corporation” for U.S. federal income tax purposes. However, the determination as to whether Pubco is or will become a “United States real property holding corporation” will not be made until a future tax year, and there can be no assurance that Pubco will not become such a corporation in the future.

Tax Consequences to Non-U.S. Holders That Elect to Have Their Public Shares Redeemed for Cash

This section is addressed to Non-U.S. Holders of Public Shares that elect to have their Public Shares redeemed for cash. For purposes of this description, a “Redeeming Non-U.S. Holder” is a Non-U.S. Holder that so redeems its Public Shares.

Except as otherwise described in this section, a Redeeming Non-U.S. Holder who elects to have its Public Shares redeemed for cash will generally be treated in the same manner as a Redeeming U.S. Holder for U.S. federal income tax purposes.

A Redeeming Non-U.S. Holder will not be subject to U.S. federal income tax on any gain recognized as a result of the exchange unless:

• such Redeeming Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year in which the redemption takes place and certain other conditions are met; or

• such Redeeming Non-U.S. Holder is engaged in a trade or business within the United States and any gain recognized in the exchange is treated as effectively connected with such trade or business (and, if required by an applicable income tax treaty, the gain is attributable to a United States permanent establishment of such Non-U.S. Holder), in which case the Redeeming Non-U.S. Holder will generally be subject to the same treatment as a Redeeming U.S. Holder with respect to the exchange, and a Redeeming Non-U.S. Holder that is classified as a corporation for U.S. federal income tax purposes may be subject to an additional branch profits tax at a 30% rate (or lower rate as may be specified by an applicable income tax treaty).

With respect to any redemption of Public Shares for cash that is treated as a distribution rather than a sale, any amount treated as dividend income received by a Redeeming Non-U.S. Holder will generally be subject to U.S. withholding tax at a rate of 30%, unless the Redeeming Non-U.S. Holder is entitled to a reduced rate of withholding under an applicable income tax treaty. However, dividends received by a Redeeming Non-U.S. Holder that are effectively connected with such holder’s conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, such dividends are attributable to a United States permanent establishment of the Redeeming Non-U.S. Holder), will be taxed as described above under “— U.S. Holders — Tax Consequences to U.S. Holders That Elect to Have Their Public Shares Redeemed for Cash.” In addition, dividends received by a Redeeming Non-U.S. Holder that is classified as a corporation for U.S. federal income tax purposes that are effectively connected with the holder’s conduct of a U.S. trade or business may also be subject to an additional branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty.

160

Non-U.S. Holders of Public Shares considering exercising their redemption rights should consult their own tax advisors as to whether the redemption of their shares will be treated as a sale or as a distribution under the Code.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code and the Treasury Regulations and administrative guidance promulgated thereunder commonly referred as the Foreign Account Tax Compliance Act (“FATCA”) generally impose withholding at a rate of 30% in certain circumstances on dividends in respect of securities (including Pubco Class A Common Stock) which are held by or through certain foreign financial institutions (including investment funds), unless any such institution (i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (ii) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which shares of Pubco Class A Common Stock are held will affect the determination of whether such withholding is required. Similarly, dividends in respect of Pubco Class A Common Stock held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exceptions will generally be subject to withholding at a rate of 30%, unless such entity either (i) certifies to the applicable withholding agent that such entity does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners”, which will in turn be provided to the U.S. Department of Treasury. All holders should consult their tax advisors regarding the possible implications of FATCA on their ownership of Pubco Class A Common Stock.

(2) at the MLAC Merger Effective Time:

(i) each issued and outstanding MLAC Right shall be automatically converted into the number of shares of Pubco Class A Stock that would have been received by the holder thereof if the MLAC Right had been converted upon the consummation of a Business Combination in accordance with MLAC’s Organizational Documents, the MLAC IPO Prospectus and the MLAC Rights Agreement into MLAC Class A Ordinary Shares, but for such purposes treating it as if (a) such Business Combination had occurred immediately prior to the MLAC Merger Effective Time and (b) the MLAC Class A Ordinary Shares issued upon conversion of the MLAC Rights had then automatically been converted into shares of Pubco Class A Stock in accordance with the provisions of limb (2)(ii). At the MLAC Merger Effective Time, the MLAC Rights shall cease to be outstanding and shall automatically be canceled and retired and shall cease to exist;

(ii) each issued and outstanding MLAC Class A Ordinary Share (other than (x) treasury shares and (y) shares in respect of which its holder has validly exercised its right of redemption) shall be converted automatically into one (1) share of Pubco Class A Stock, following which all such MLAC Class A Ordinary Shares (other than the treasury shares) shall cease to be outstanding and shall automatically be canceled and shall cease to exist;

If there are any MLAC Ordinary Shares that are owned by MLAC as treasury shares, such treasury shares will be automatically canceled without any conversion thereof or payment therefore.

Earnout Shares

Upon the Closing, 2,000,000 of the Astral Earnout Shares will be deposited into the Astral Escrow Account, and will be released in tranches, all as provided in the Business Combination Agreement and the Astral Escrow Agreement. Unless released earlier, in accordance with the Astral Escrow Agreement and Business Combination Agreement, the Astral Earnout Shares will be held in escrow for the Escrow Period. The Astral Earnout Shares, together with any shares received upon equitable adjustment of the Astral Earnout Shares, shall be subject to the Astral Transfer at the end of the Earnout Period in the event that not all of the Triggering Events are achieved by Pubco during the Earnout Period.

The Astral Earnout Shares shall vest, shall no longer be subject to the Astral Transfer and shall be released from the Astral Escrow Account to Astral, in the amounts specified below, upon Pubco meeting the price milestones specified below:

Each Triggering Event shall only occur once, if at all, and all Astral Earnout Shares not released by the end of the Earnout Period will be transferred to Pubco through an Astral Transfer, in each case as set forth in the Business Combination Agreement.

166

Accounting for the Business Combination

The Business Combination will be accounted for as a reverse recapitalization, in accordance with U.S. GAAP. Under this method of accounting, MLAC will be treated as the “acquired” company for financial reporting purposes, and AVAT will be the accounting “acquirer” This determination was primarily based on the assumption that:

• AVAT’s members will hold a majority of the voting power of Pubco post Business Combination;

• The Pubco Board will consist of one (1) or more members, each of whom shall be a natural person; and

• AVATs operations will substantially comprise the ongoing operations of Pubco; and

• AVAT’s senior management will comprise the senior management of Pubco.

Another determining factor was that MLAC does not meet the definition of a “business” pursuant to ASC 805-10-55, and thus, for accounting purposes, the Business Combination will be accounted for as a reverse recapitalization, within the scope of ASC 805. The net assets of MLAC will be stated at historical cost, with no goodwill or other intangible assets recorded.

Basis of Pro Forma Presentation

Pubco has elected to provide the unaudited pro forma condensed combined financial information under two different redemption scenarios of Public Shares into cash as more fully described below:

• Scenario 1 — Assuming No Redemptions: This presentation assumes that no Public Shareholders exercise redemption rights with respect to their Public Shares upon consummation of the Business Combination.

• Scenario 2 — Assuming Maximum Redemptions: This presentation assumes that Public Shareholders holding 22,905,484 Public Shares exercise their redemption rights for $242.3 million in the aggregate upon consummation of the Business Combination at a redemption price of approximately $10.58 per share as of March 31, 2026. The Maximum Redemptions scenario reflects the maximum number of Public Shares that can be redeemed while maintaining the requirement that the $1.0 million underwriting fee is paid from the funds on deposit in the Trust Account pursuant to the Amended Underwriting Agreement and includes all adjustments contained in the “No Redemptions” scenario and presents additional adjustments to reflect the effect of the Maximum Redemptions scenario.

The following tables set out the Class A and Class B share ownership of Pubco on a pro forma basis assuming the No Redemptions scenario and the Maximum Redemptions scenario:

	No Redemptions			Maximum Redemptions

Unless released earlier, in accordance with the Astral Escrow Agreement and Business Combination Agreement, the Astral Earnout Shares will be held in escrow for the Escrow Period. The Astral Earnout Shares, together with any shares received upon equitable adjustment of the Astral Earnout Shares, shall be subject to the Astral Transfer at the end of the Earnout Period in the event that not all of the Triggering Events are achieved by Pubco during the Earnout Period.

Note 2 — Basis of Presentation and Accounting Policies

The unaudited pro forma condensed combined financial information is for illustrative purposes only. The financial results may have been different had the companies always been combined. You should not rely on the unaudited pro forma condensed combined financial information as being indicative of the historical results that would have been achieved had the companies always been combined or the future results that Pubco will experience. AVAT and MLAC did not have any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” Release No. 33-10786 replaces the existing pro forma adjustment criteria with simplified Transaction Accounting Adjustments and presents the Management’s Adjustments. Pubco has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the following unaudited pro forma condensed combined financial information.

MLAC does not meet the definition of a “business” pursuant to ASC 805-10-55 as it is an empty listed shell holding only cash raised as part of its original equity issuance. As a result, the Business Combination does not qualify as a “business combination” within the meaning of ASC 805, Business Combinations; rather, the Business Combination will be accounted for as a reverse merger in accordance with U.S. GAAP. See Note 3 — Accounting for the Business Combination for more details.

The historical financial statements of Pubco have been prepared in accordance with U.S. GAAP. The historical financial statements of AVAT have been prepared in accordance with U.S. GAAP. The historical financial statements of MLAC have been prepared in accordance with U.S. GAAP. The unaudited pro forma condensed combined financial information reflects U.S. GAAP, the basis of accounting used by AVAT.

Pubco has elected to provide the unaudited pro forma condensed combined financial information under two different redemption scenarios of Public Shares into cash as more fully described below:

• Scenario 1 — Assuming No Redemptions: This presentation assumes that no Public Shareholders exercise redemption rights with respect to their Public Shares upon consummation of the Business Combination.

• Scenario 2 — Assuming Maximum Redemptions: This presentation assumes that Public Shareholders holding 22,905,484 Public Shares exercise their redemption rights for $242.4 million in the aggregate upon consummation of the Business Combination at a redemption price of approximately $10.58 per share as of March 31, 2026. The Maximum Redemptions scenario reflects the maximum number of Public Shares that can be redeemed while maintaining the requirement that the $1.0 million underwriting fee is paid from the funds on deposit in the Trust Account pursuant to the Amended Underwriting Agreement and includes all adjustments contained in the “No Redemptions” scenario and presents additional adjustments to reflect the effect of the Maximum Redemptions scenario.

The following tables set out the Class A and Class B share ownership of Pubco on a pro forma basis assuming the No Redemptions scenario and the Maximum Redemptions scenario:

	No Redemptions			Maximum Redemptions
	Number of	Percent		Number of	Percent

	Number of	Percent		Number of	Percent
Pro Forma Ownership	Shares	Outstanding		Shares	Outstanding
Seller Related Parties	5,805,638	100.0	%	5,805,638	100.0	%
Total shares of Pubco Class B Stock outstanding	5,805,638			5,805,638

The pro forma adjustments do not have an income tax effect as they are either (i) incurred by legal entities that are not subject to a corporate income tax, or (ii) permanently non-deductible or non-taxable based on the laws of the relevant jurisdiction.

Upon consummation of the Business Combination, management will perform a comprehensive review of the three entities’ accounting policies. As a result of the review, management may identify differences between the accounting policies of the three entities which, when conformed, could have a material impact on the financial statements of Pubco. Management did not identify any differences that would have a material impact on the unaudited pro forma condensed combined financial information. As a result, the unaudited pro forma condensed combined financial information does not assume any differences in accounting policies.

176

Note 3 — Accounting for the Business Combination

The Business Combination will be accounted for as a reverse recapitalization, in accordance with U.S. GAAP. Under this method of accounting, MLAC will be treated as the “acquired” company for financial reporting purposes, and AVAT will be the accounting “acquirer” This determination was primarily based on the assumption that:

• AVAT’s members will hold a majority of the voting power of Pubco post Business Combination;

• The Pubco Board will consist of one (1) or more members, each of whom shall be a natural person; and

• AVATs operations will substantially comprise the ongoing operations of Pubco; and

• AVAT’s senior management will comprise the senior management of Pubco.

Another determining factor was that MLAC does not meet the definition of a “business” pursuant to ASC 805-10-55, and thus, for accounting purposes, the Business Combination will be accounted for as a reverse recapitalization, within the scope of ASC 805. The net assets of MLAC will be stated at historical cost, with no goodwill or other intangible assets recorded.

Note 4 — Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet as of December 31, 2025

As the Business Combination is being reflected as if it had occurred at the beginning of the period presented, the calculation of weighted average shares outstanding for basic and diluted loss per share assumes that the shares issued in connection with the Business Combination have been outstanding for the entire period presented. If the number of public shares described under the “Assuming Maximum Redemptions” scenario described above are redeemed, this calculation is retroactively adjusted to eliminate such shares for the entire period. Pubco Class B Stock has not been included in the loss per share calculation as the holder of shares of Pubco Class B Stock will not be entitled to economic rights.

INFORMATION ABOUT MLAC

Overview

MLAC is a blank check company incorporated in the Cayman Islands on June 14, 2024, for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities. MLAC is an early stage and emerging growth company and, as such, MLAC is subject to all of the risks associated with early stage and emerging growth companies.

On June 27, 2024, the Sponsor made a capital contribution of $25,000 to cover certain expenses on behalf of MLAC in exchange for issuance of 7,187,500 MLAC Class B Ordinary Shares (the “MLAC Founder Shares”). Subsequently, on December 12, 2024, MLAC, through a share capitalization, issued an additional 359,375 MLAC Founder Shares to the Sponsor, resulting in an aggregate of 7,546,875 MLAC Founder Shares issued and outstanding. The holders of the MLAC Founder Shares agreed to forfeit and cancel up to an aggregate of 984,375 MLAC Founder Shares, on a pro rata basis, to the extent that the option to purchase additional MLAC Units is not exercised in full by the underwriters. The forfeiture will be adjusted to the extent that the option to purchase additional MLAC Units is not exercised in full by the underwriters so that the MLAC Founder Shares will represent approximately 23.2% of all of MLAC’s issued and outstanding shares after the initial public offering. On December 16, 2024, the underwriters partially exercised their over-allotment option as part of the closing of the Initial Public Offering and forfeited their option to exercise the remaining over-allotment option. As such, 359,375 MLAC Founder Shares were forfeited and resulted in a total number of 7,187,500 MLAC Class B Ordinary Shares outstanding.

On December 16, 2024, MLAC consummated its initial public offering of 23,000,000 MLAC Units. Each MLAC Unit consists of one MLAC Class A Ordinary Share and one MLAC Right, with each MLAC Right entitling the holder thereof to receive one-tenth of one MLAC Class A Ordinary Share upon the consummation of an initial business combination. The MLAC Units were sold at a price of $10.00 per unit, generating gross proceeds to MLAC of $230,000,000. MLAC granted BTIG, the representative of the several underwriters of the MLAC IPO, a 45-day option to purchase up to 3,150,000 additional MLAC Units solely to cover over-allotments, if any. On December 13, 2024, the underwriters partially exercised the over-allotment option to purchase an additional 2,000,000 MLAC Units.

Simultaneously with the closing of MLAC IPO, MLAC completed the private sale of an aggregate of 805,000 MLAC Private Placement Shares to the Sponsor and BTIG at a purchase price of $10.00 per unit, generating gross proceeds to MLAC of $8,050,000.

Since the MLAC IPO, MLAC’s activity has been limited to the search and evaluation of and negotiation with acquisition targets for its initial business combination.

MLAC has until June 16, 2026 (18 months from the closing of the MLAC IPO), or until such earlier liquidation date as the MLAC Board may approve or such later date as the MLAC Shareholders may approve pursuant to the MLAC Memorandum and Articles, to consummate an initial business combination.

MLAC Units, MLAC Class A Ordinary Shares and MLAC Rights are traded on The Nasdaq Global Market under the symbols “MLACU,” “MLAC” and “MLACR,” respectively. MLAC Units commenced public trading on December 16, 2024, and MLAC Class A Ordinary Shares and MLAC Rights commenced separate trading on February 3, 2025.

Prior SPAC Experience

MLAC’s Chairman and Chief Executive Officer, Paul Grinberg, and MLAC’s President and Chief Financial Officer, Douglas Horlick, and MLAC’s independent directors have other experience with blank check companies, having served as executive officers and directors in two other SPACs:

Mountain Lake Acquisition Corp. II: MLAC II, a special purpose acquisition company, completed a $360 million initial public offering in January 2026 and has been searching and identifying the target of an initial business combination. On April 9, 2026, MLAC II entered into a non-binding letter of intent to enter into a business combination with Terra Quantum AG (“Terra Quantum”), a quantum technology company.

181

Social Leverage Acquisition Corp I: Mr. Grinberg served as the Executive Chairman of Social Leverage Acquisition Corp I (“SLAC”). Mr. Horlick served as President and Chief Operating Officer of SLAC, and Mr. Marquez was an independent director of SLAC. SLAC completed its initial public offering of 34,500,000 units in February 2021, in which it raised aggregate proceeds of approximately $345 million. After SLAC’s IPO, SLAC’s management team commenced an active search for prospective businesses and/or assets to acquire in its initial business combination. On July 31, 2022, SLAC entered into a Business Combination Agreement with W3BCLOUD Holdings Inc. The business combination was terminated due to changes in market conditions. On February 12, 2024, the board of directors of SLAC determined that it would not be able to complete an initial business combination within the period required. SLAC announced that it would not consummate an initial business combination and it would redeem its public shares. SLAC has been dissolved and liquidated following the redemption. Its securities were no longer listed on Nasdaq.

Other than as described above, MLAC’s sponsor and its affiliates are not involved in any other special purpose acquisition companies.

Recent Developments

The Business Combination Agreement

On October 1, 2025, MLAC, Pubco, the Pubco Subsidiaries, the Company and Seller entered into the Business Combination Agreement. On January 13, 2026 and on March 17, 2026, MLAC, Pubco, the Pubco Subsidiaries, the Company, Seller Related Parties and Astral entered certain amendments to the Business Combination Agreement, effective as of October 1, 2025.

Astral is a Delaware limited partnership whose general partner is Astral Horizon GP, LLC. The limited partners of Astral are certain senior managers and employees of the Seller and the general partners of the DVs. Astral Horizon GP, LLC is managed by some of the same individuals who serve as the managers of the general partners of the DVs. Accordingly, Astral is a related party to the Seller Related Parties by virtue of common management and overlapping ownership among their respective principals. The Additional Merger Consideration Shares are being issued to Astral in consideration for advisory and strategic services provided by Astral’s limited partners in connection with the structuring and execution of the Business Combination and the establishment of Pubco. Such services included, but were not limited to:

(i) Executive Recruitment: Astral’s limited partners assisted in identifying, evaluating, and recruiting the Chief Executive Officer of Pubco; and

(ii) Tax and Corporate Structuring Advisory: Astral’s limited partners provided strategic advice regarding aspects of the tax and corporate structuring of the Business Combination and post-Closing operations of Pubco.

Consequently, (i) on January 13, 2026, the Parties entered into the First Amendment to the Business Combination Agreement, pursuant to which, inter alia, the 4,000,000 Additional Merger Consideration Shares (i.e., the 2,000,000 Astral Post-Closing Shares and the 2,000,000 Astral Earnout Shares) will be issued, on the Company Merger Effective Date, to Astral (the Astral Earnout Shares being held in escrow for the Escrow Period to only be released in accordance with the Astral Escrow Agreement), and (ii) on March 17, 2026, the Parties entered into the Second Amendment to the Business Combination Agreement, pursuant to which the issuance by Pubco to Astral of the 2,000,000 Astral Post-Closing Shares will occur on the thirtieth (30th) calendar day following the Closing Date, rather than on the Company Merger Effective Date.

Business Combination Agreement Amendments

On January 13, 2026, MLAC, Pubco, the Pubco Subsidiaries, the Company, Seller Related Parties and Astral entered into the First Amendment, and pursuant to which, among other things, the parties thereto agree that:

(i) Astral and the DVs were added as parties to the Business Combination Agreement and they agreed to be bound by, and to comply with, the terms and conditions of the Business Combination Agreement, in the same manner as if they were original signatories thereto;

(ii) the Company Units held by the DVs are to be treated as the Company Units held by Seller such that, as a result of the Company Merger, the DVs will receive one (1) Pubco Class A Stock and one (1) Pubco Class B Stock for each Company Unit held by the DVs;

(iii) the Additional Merger Consideration Shares to be issued at Closing will (a) be issued to Astral rather than to Seller as provided in the original version of the Business Combination Agreement, and (b) consist of 4,000,000 shares of Pubco Class A Stock only, with no Pubco Class B Stock to be allotted as Additional Consideration because Pubco Class B Stock will be issued to Seller Related Parties;

(iv) the Representations and Warranties of the Seller are to be made severally but not jointly by the Seller Related Parties and Astral rather than solely by Seller as provided in the original version of the Business Combination Agreement;

(v) certain references to the Seller (as specified in the First Amendment) shall be considered as references to the Seller Related Parties, Astral or the Seller Related Parties and/or Astral, as applicable;

(vi) Exhibit E (Terms of Pubco Stock) to the original version of the BCA be deleted in its entirety and replaced by the new Exhibit E, in the form attached to the First Amendment.

(vii) The First Amendment is effective as of October 1, 2025.

On March 17, 2026, MLAC, Pubco, the Pubco Subsidiaries, the Company, Seller Related Parties and Astral entered into the Second Amendment, and pursuant to which, among other things, the parties thereto agree to postpone the issuance by Pubco to Astral of the Astral Post-Closing Shares for a period of thirty (30) calendar days, so that such issuance will occur on the thirtieth (30th) calendar day following the Closing Date, rather than on the Company Merger Effective Date. The Second Amendment is effective as of October 1, 2025.

Amendment to Underwriting Agreement

On October 1, 2025, BTIG and MLAC entered into an amendment to the underwriting agreement in connection with MLAC’s IPO, pursuant to which, BTIG may receive a deferred fee equal to $1,000,000, and such fees are payable at the closing of the Business Combination only if MLAC completes the Business Combination; and pursuant to the Sponsor Support Agreement, BTIG will forfeit its 310,000 MLAC Private Placement Shares; and

On October 1, 2025, BTIG and MLAC entered into the BTIG Financial Advisory Services Agreement, pursuant to which, BTIG may receive reimbursement of all reasonable out-of-pocket expense as financial advisor to MLAC in connection with the Business

183

Combination, (provided that, if the expense exceeding $100,000, BTIG shall submit to MLAC for its prior written approval), such reimbursement are payable at the closing of the Business Combination only if MLAC completes an initial business combination.

Company Unit Subscription

Concurrently with the execution of the Business Combination Agreement, Pubco, the Company and MLAC entered into the Company Unit Subscription Agreements with the Company Unit Investors, pursuant to which the Company Unit Investors agreed to purchase, payable in cash, USDC or AVAX (or a combination of cash, USDC and/or AVAX), and the Company agreed to issue and sell, approximately $216 million worth of Company Units at the Per Unit Price, upon the terms and subject to the conditions set forth therein. Company Unit Investors received a number of Company Units equal to (a) if the Company Unit Investor elected to purchase Company Units by contributing AVAX, the Stated AVAX Amount multiplied by the Applicable Signing AVAX Price, or (b) if the Company Unit Investor elected to purchase the Company Units by contributing cash or USDC, the Stated Dollar Amount or the Stated USDC Amount (as applicable) divided by the Per Unit Price. For more information about the Company Unit Subscription Agreements, please see the section entitled “The Business Combination — Other Transaction Agreements — The Company Unit Subscription Agreements.”

Fair Market Value of Acquisition Target

So long as MLAC maintains a listing for its securities on Nasdaq, MLAC must complete one or more business combinations having an aggregate fair market value of at least 80% of the value of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest income earned on the Trust Account) at the time of signing a definitive agreement in connection with its initial business combination. As discussed in the Section titled “The Business Combination Proposal — Satisfaction of 80% Test,” the MLAC Board made the determination as to the fair market value of the Business Combination and that this test was met in connection with the proposed Business Combination with AVAT. The MLAC Board believes that the financial skills and background of its members qualified it to conclude that the Business Combination with AVAT met this requirement.

Voting Restrictions in Connection with the Meeting

MLAC Shareholders will be entitled to vote or direct votes to be cast at the Meeting if they owned MLAC Ordinary Shares at the close of business on           , 2026, which is the Record Date for the Meeting. MLAC Shareholders are entitled to one vote at the Meeting for each MLAC Ordinary Share held as of the Record Date. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the Public Shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your Public Shares or, if you wish to attend the Meeting and vote, obtain a proxy from your broker, bank or nominee.

Redemption Rights for Public Shareholders upon Completion of the Business Combination

Under the MLAC Memorandum and Articles, in connection with any proposed initial business combination, if MLAC seeks shareholder approval of an initial business combination, Public Shareholders must be offered the opportunity to redeem their Public Shares, regardless of whether they vote for or against the proposed initial business combination, subject to the limitations described in the MLAC Memorandum and Articles as described in the MLAC IPO Prospectus and herein. Accordingly, in connection with the Business Combination with AVAT, Public Shareholders may seek to redeem their Public Shares in accordance with the procedures set forth in this proxy statement/prospectus. Notwithstanding the foregoing, the MLAC Memorandum and Articles provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than 15% or more of the Public Shares in the aggregate, without the prior consent of MLAC.

Redemption of Public Shares and Liquidation if no Initial Business Combination

The MLAC Memorandum and Articles provides that MLAC will have only an 18-month duration to complete its initial business combination. If MLAC is unable to complete its initial business combination within such 18-month period, MLAC will, as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash,

184

equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will constitute full and complete payment for the Public Shares and completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidating or other distributions, if any)

MLAC’s initial shareholders, Sponsor, officers and directors have entered into the Insider Letter with MLAC, pursuant to which they have waived their rights to liquidating distributions from the Trust Account with respect to any MLAC Ordinary Shares they hold if MLAC fails to complete its initial business combination within the completion window, although they will be entitled to liquidating distributions from assets outside the Trust Account. However, if MLAC’s initial shareholders, Sponsor or management team acquire Public Shares, they will be entitled to liquidating distributions from the Trust Account and liquidating distributions from assets outside the Trust Account with respect to such Public Shares if MLAC fails to complete its initial business combination within the allotted 18-month time period.

MLAC’s initial shareholders, Sponsor, officers and directors have agreed, pursuant to the Insider Letter with MLAC, that they will not propose any amendment to the MLAC Memorandum and Articles (A) to modify the substance or timing of its obligation to redeem 100% of the Public Shares if MLAC does not complete its initial business combination within the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity, unless MLAC provides its Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares.

MLAC expects that all costs and expenses associated with implementing its plan of dissolution, as well as payments to any creditors, will be funded from the amounts remaining outside the Trust Account, although MLAC cannot assure you that there will be sufficient funds for such purpose. However, if those funds are not sufficient to cover the costs and expenses associated with implementing its plan of dissolution, to the extent that there is any interest accrued in the Trust Account not required to pay taxes, MLAC may request the trustee to release to MLAC an additional amount of up to $100,000 of such accrued interest to pay those costs and expenses.

If MLAC were to expend all of the net proceeds of the MLAC IPO and the sale of the MLAC Private Placement Shares, other than the proceeds deposited in the Trust Account, and without taking into account interest, if any, earned on the Trust Account and any tax payments or expenses for the dissolution of the trust, the per-share redemption amount received by shareholders upon its dissolution would be approximately $10.05. The proceeds deposited in the Trust Account could, however, become subject to the claims of its creditors which would have higher priority than the claims of its Public Shareholders. MLAC cannot assure you that the actual per-share redemption amount received by shareholders will not be substantially less than $10.05. While MLAC intends to pay such amounts, if any, MLAC cannot assure you that MLAC will have funds sufficient to pay or provide for all creditors’ claims.

Although MLAC will seek to have all vendors, service providers (other than its independent registered public accounting firm), prospective target businesses and other entities with which MLAC does business execute agreements waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of the Public Shareholders, there is no guarantee that they will execute such agreements or even if they execute such agreements that they would be prevented from bringing claims against the Trust Account including but not limited to fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain an advantage with respect to a claim against its assets, including the funds held in the Trust Account. If any third party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, the management will consider whether competitive alternatives are reasonably available to MLAC and will only enter into an agreement with such third party if management believes that such third party’s engagement would be in the best interests of MLAC under the circumstances. Examples of possible instances where MLAC may engage a third party that refuses to execute a waiver including the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. The underwriters of the MLAC IPO and the independent registered public accounting firm will not execute agreements with MLAC waiving such claims to the monies held in the Trust Account. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with MLAC and will not seek recourse against the Trust Account for any reason. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to MLAC if and to the

185

extent any claims by a third party for services rendered or products sold to MLAC (except for MLAC’s independent auditors), or a prospective target business with which MLAC has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under its indemnity of the underwriters of the MLAC IPO against certain liabilities, including liabilities under the Securities Act. However, MLAC has not asked the Sponsor to reserve for such indemnification obligations, nor has MLAC independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and MLAC believes that the Sponsor’s only assets are its securities. Therefore, MLAC cannot assure you that the Sponsor would be able to satisfy those obligations. As a result, if any such claims were successfully made against the Trust Account, the funds available for the initial business combination and redemptions could be reduced to less than $10.05 per Public Share. In such event, MLAC may not be able to complete the initial business combination, and you would receive such lesser amount per share in connection with any redemption of your Public Shares. None of MLAC’s officers or directors will indemnify MLAC for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

In the event that the proceeds in the Trust Account are reduced below the lesser of (i) $10.05 per Public Share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.05 per share due to reductions in the value of the trust assets, in each case less taxes payable, and the Sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, the independent directors would determine whether to take legal action against the sponsor to enforce its indemnification obligations. While MLAC currently expects that the independent directors would take legal action on its behalf against the Sponsor to enforce its indemnification obligations to MLAC, it is possible that the independent directors in exercising their business judgment may choose not to do so in any particular instance. Accordingly, MLAC cannot assure you that due to claims of creditors the actual value of the per-share redemption price will not be less than $10.05 per share.

MLAC will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which MLAC does business execute agreements waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. The Sponsor will also not be liable as to any claims under the indemnity of the underwriters of the MLAC IPO against certain liabilities, including liabilities under the Securities Act.

If MLAC files a bankruptcy or winding-up petition or an involuntary bankruptcy or winding-up petition is filed against MLAC that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy or insolvency law, and may be included in its bankruptcy estate and subject to the claims of third parties with priority over the claims of MLAC’s Shareholders. To the extent any bankruptcy claims deplete the Trust Account, MLAC cannot assure you MLAC will be able to return $10.05 per share to the Public Shareholders. Additionally, if MLAC files a bankruptcy or winding-up petition or an involuntary bankruptcy or winding-up petition is filed against MLAC that is not dismissed, any distributions received by shareholders could be viewed under applicable debtor/creditor and/or bankruptcy or insolvency laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy or insolvency court could seek to recover some or all amounts received by MLAC’s Shareholders. Furthermore, MLAC Board may be viewed as having breached its fiduciary duty to its creditors and/or may have acted in bad faith, and thereby exposing itself and MLAC to claims of punitive damages, by paying Public Shareholders from the Trust Account prior to addressing the claims of creditors. MLAC cannot assure you that claims will not be brought against MLAC for these reasons.

MLAC’s Public Shareholders will be entitled to receive funds from the Trust Account only (i) in the event of the redemption of the Public Shares if MLAC does not complete the initial business combination within the completion window, (ii) in connection with a shareholder vote to amend the MLAC Memorandum and Articles (A) to modify the substance or timing of its obligation to redeem 100% of the Public Shares if MLAC does not complete the initial business combination within the completion window or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity or (iii) if they redeem their respective shares for cash upon the completion of the initial business combination. In no other circumstances will a shareholder have any right or interest of any kind to or in the Trust Account. In the event MLAC seeks shareholder approval in connection with the initial business combination, a shareholder’s voting in connection with the business combination alone will not result in a shareholder’s redeeming its shares to MLAC for an applicable pro rata share of the Trust Account. Such shareholder must

186

have also exercised its redemption rights described above. These provisions of MLAC Memorandum and Articles, like all provisions of MLAC Memorandum and Articles, may be amended with a shareholder vote.

Employees

MLAC currently has two executive officers: Paul Grinberg, the Chief Executive Officer and Douglas Horlick, the Chief Financial Officer. These individuals are not obligated to devote any specific number of hours to MLAC’s matters but they intend to devote as much of their time as they deem necessary to MLAC’s affairs until MLAC has completed its initial business combination. MLAC does not intend to have any full time employees prior to the completion of its initial business combination.

Number and Terms of Office of Officers and Directors

MLAC Board consists of five members and is divided into three classes, with only one class of directors being elected in each year, and with each class (except for those directors appointed prior to MLAC’s first annual meeting of shareholders) serving a three-

188

year term. The term of office of the first class of directors, consisting of Jeffrey T. Lager and Michael Marquez, will expire at MLAC’s first annual meeting of MLAC Shareholders. The term of office of the second class of directors, consisting of Jaime W. Vieser and Douglas Horlick, will expire at MLAC’s second annual meeting of MLAC Shareholders. The term of office of the third class of directors, consisting of Paul Grinberg, will expire at MLAC’s third annual meeting of MLAC Shareholders.

Approval of MLAC’s initial business combination will require the affirmative vote of a majority of MLAC Board, which must include a majority of MLAC’s independent directors. Subject to any other special rights applicable to the shareholders, prior to MLAC’s initial business combination, any vacancies on MLAC Board may be filled by the affirmative vote of a majority of the directors present and voting at the meeting of MLAC Board. MLAC’s officers are appointed by the MLAC Board and serve at the discretion of the MLAC Board, rather than for specific terms of office. MLAC Board is authorized to appoint persons to the offices set forth in MLAC Memorandum and Articles as it deems appropriate. MLAC Memorandum and Articles provides that MLAC officers may consist of a Chairman of the Board, a Chief Executive Officer, a President, a Chief Operating Officer, a Chief Financial Officer, Vice Presidents, a Secretary, Assistant Secretaries, a Treasurer and such other offices as may be determined by the MLAC Board.

Director Independence

The Nasdaq listing rules require that a majority of MLAC Board be independent within one year of MLAC IPO. An “independent director” is defined generally as a person that, in the opinion of the company’s board of directors, has no material relationship with the listed company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the company). MLAC Board has determined that each of Messrs. Jaime W. Vieser, Michael Marquez and Jeffrey T. Lager is an independent director under applicable SEC and Nasdaq rules. MLAC’s independent directors will have regularly scheduled meetings at which only independent directors are present.

Executive Officer and Director Compensation

The Sponsor transferred an aggregate of 50,000 of its MLAC Class B Ordinary Shares, or 25,000 each to Jeffrey T. Lager and Michael Marquez, two of MLAC’s independent directors, at the closing of the MLAC IPO. Paul Grinberg, Douglas Horlick and Jaime W. Vieser own membership interests in the Sponsor which paid a nominal aggregate purchase price of $25,000 for the MLAC Founder Shares, or approximately $0.003 per share.

MLAC agreed, commencing on the closing of the MLAC IPO through the earlier of consummation of the initial Business Combination and the liquidation, to pay the Chairman and Chief Executive Officer and the President and Chief Financial Officer, a total of up to $20,000 per month for their services as executive officers and directors of MLAC. For the year ended December 31, 2025, MLAC incurred and paid an expense of $240,000 of fees for these services, respectively. For the period from June 14, 2024 (inception) through December 31, 2024, no fees were incurred for these services. Upon completion of the Business Combination, MLAC will cease paying these monthly fees.

Except for Mr. Grinberg and Mr. Horlick, none of MLAC’s directors or officers have received any compensation for services rendered to MLAC. No finder’s fee, reimbursement, consulting fee or monies in respect of any payment of a loan, will be paid by MLAC to the Sponsor, officers and directors, or any affiliate of theirs, for services rendered prior to, or for any services rendered in order to effectuate, the consummation of the Business Combination. However, these individuals are entitled to certain payments including, but not limited to, reimbursement for any out-of-pocket expenses incurred in connection with activities on MLAC’s behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Additionally, these individuals will be eligible to receive a transfer or reallocation of MLAC Founder Shares for any extraordinary services rendered in order to identify or effectuate the consummation of the Business Combination. MLAC’s audit committee reviews on a quarterly basis all payments that were made to the Sponsor, officers or directors, or MLAC’s or their affiliates. All such payments are made using funds held outside the Trust Account. Other than quarterly audit committee review of such payments, MLAC does not have any additional controls in place governing its reimbursement payments to its directors and officers for their out-of-pocket expenses incurred in connection with identifying and consummating an initial business combination.

After the completion of the Business Combination, directors or members of MLAC’s management team who remain with Pubco may be paid consulting, management or director fees from Pubco. MLAC has not established any limit on the amount of such fees that may be paid by Pubco to MLAC’s directors or members of management. Any compensation to be paid to MLAC’s officers will be determined, or recommended to the Pubco Board for determination, either by a compensation committee constituted solely by independent directors or by a majority of the independent directors on the Pubco Board. Other than Mr. Grinberg, who is expected to be nominated as a director of Pubco following the Closing, none of MLAC’s directors or officers are expected to remain with Pubco after the Closing or receive any fees from Pubco for providing any services in their capacity as such.

189

MLAC does not intend to take any action to ensure that members of MLAC’s management team maintain their positions with Pubco after the Closing. MLAC is not a party to any agreements with MLAC’s officers and directors that provide for benefits upon termination of employment.

Committees of the MLAC Board

MLAC Board has three standing committees: an audit committee; a compensation committee; and a nominating and corporate governance committee. Subject to phase-in rules, the Nasdaq listing rules and Rule 10A-3 of the Exchange Act require that the audit committee of a listed company be comprised solely of independent directors, and Nasdaq listing rules require that the compensation committee and the nominating and corporate governance committee of a listed company be comprised solely of independent directors. Each committee operates under a charter that has been approved by MLAC Board and has the composition and responsibilities described below.

MLAC Audit Committee

MLAC has established an audit committee of the board of directors. The initial members of the audit committee are Jaime W. Vieser, Michael Marquez and Jeffrey T. Lager, each of whom meet the independent director standard under Nasdaq listing standards and under Rule 10-A-3(b)(1) of the Exchange Act. Mr. Michael Marquez will serve as chairperson of the audit committee.

Each member of the audit committee is financially literate and MLAC Board has determined that each of Jaime W. Vieser, Michael Marquez and Jeffrey T. Lager qualifies as an “audit committee financial expert” as defined in applicable SEC rules and has accounting or related financial management expertise.

MLAC has adopted an audit committee charter, which details the principal functions of the audit committee, including:

• assisting board oversight of (1) the integrity of its financial statements, (2) its compliance with legal and regulatory requirements, (3) its independent auditor’s qualifications and independence, and (4) the performance of its internal audit function and independent auditors; the appointment, compensation, retention, replacement, and oversight of the work of the independent auditors and any other independent registered public accounting firm engaged by MLAC;

• pre-approving all audit and non-audit services to be provided by the independent auditors or any other registered public accounting firm engaged by MLAC, and establishing pre-approval policies and procedures; reviewing and discussing with the independent auditors all relationships the auditors have with MLAC in order to evaluate their continued independence;

• setting clear policies for audit partner rotation in compliance with applicable laws and regulations; obtaining and reviewing a report, at least annually, from the independent auditors describing (1) the independent auditor’s internal quality-control procedures and (2) any material issues raised by the most recent internal quality-control review, or peer review, of the audit firm, or by any inquiry or investigation by governmental or professional authorities, within the preceding five years respecting one or more independent audits carried out by the firm and any steps taken to deal with such issues;

• meeting to review and discuss its annual audited financial statements and quarterly financial statements with management and the independent auditor, including reviewing its specific disclosures under “MLAC’s Management’s Discussion and Analysis of Financial Condition and Results of Operations”; reviewing and approving any related party transaction required to be disclosed pursuant to Item 404 of Regulation S-K promulgated by the SEC prior to MLAC entering into such transaction; and

• reviewing with management, the independent auditors, and its legal advisors, as appropriate, any legal, regulatory or compliance matters, including any correspondence with regulators or government agencies and any employee complaints or published reports that raise material issues regarding its financial statements or accounting policies and any significant changes in accounting standards or rules promulgated by the Financial Accounting Standards Board, the SEC or other regulatory authorities.

MLAC Compensation Committee

MLAC has established a compensation committee of the board of directors. The initial members of its compensation committee are Jaime W. Vieser, Michael Marquez and Jeffrey T. Lager. Under the Nasdaq listing standards and applicable SEC rules, MLAC is required to have at least two members of the compensation committee, all of whom must be independent. Jaime W. Vieser, Michael Marquez and Jeffrey T. Lager are independent and Mr. Jaime W. Vieser chairs the compensation committee.

190

MLAC has adopted a compensation committee charter, which details the principal functions of the compensation committee, including:

• reviewing and approving on an annual basis the corporate goals and objectives relevant to its chief executive officer’s compensation, evaluating its chief executive officer’s performance in light of such goals and objectives and determining and approving the remuneration (if any) of its chief executive officer based on such evaluation;

• reviewing and making recommendations to its board of directors with respect to the compensation, and any incentive compensation and equity based plans that are subject to board approval of all of its other officers;

• reviewing its executive compensation policies and plans;

• implementing and administering its incentive compensation equity-based remuneration plans;

• assisting management in complying with its proxy statement and annual report disclosure requirements;

• approving all special perquisites, special cash payments and other special compensation and benefit arrangements for its officers and employees;

• producing a report on executive compensation to be included in its annual proxy statement; and

• reviewing, evaluating and recommending changes, if appropriate, to the remuneration for directors.

MLAC shall pay Paul Grinberg, the Chairman and Chief Executive Officer and Douglas Horlick, the President Chief Financial Officer, an aggregate of up to $20,000 per month for their services as executive officers and directors of MLAC. Other than the compensation described above, no other compensation of any kind, including finders, consulting or other similar fees, will be paid to any of MLAC’s existing shareholders, officers, directors or any of their respective affiliates, prior to, or for any services they render in order to effectuate the consummation of an initial business combination. Accordingly, it is likely that prior to the consummation of an initial business combination, the compensation committee will only be responsible for the review and recommendation of any compensation arrangements to be entered into in connection with such initial business combination.

MLAC Memorandum and Articles also provides that the compensation committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, independent legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser.

However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the compensation committee will consider the independence of each such adviser, including the factors required by the Nasdaq and the SEC.

Nominating and Corporate Governance Committee

MLAC has established a nominating and corporate governance committee of the board of directors. The members of MLAC’s nominating and corporate governance are Jaime W. Vieser, Michael Marquez and Jeffrey T. Lager and Mr. Jeffrey T. Lager serves as chair of the nominating and corporate governance committee.

MLAC has adopted a nominating and corporate governance committee charter, which details the purpose and responsibilities of the nominating and corporate governance committee, including:

• identifying, screening and reviewing individuals qualified to serve as directors, consistent with criteria approved by the board, and recommending to the board of directors candidates for nomination for appointment at the annual general meeting of shareholders or to fill vacancies on the board of directors;

• developing and recommending to the board of directors and overseeing implementation of its corporate governance guidelines;

191

• coordinating and overseeing the annual self-evaluation of the board of directors, its committees, individual directors and management in the governance of MLAC; and

• reviewing on a regular basis its overall corporate governance and recommending improvements as and when necessary.

MLAC Memorandum and Articles also provides that the nominating and corporate governance committee may, in its sole discretion, retain or obtain the advice of, and terminate, any search firm to be used to identify director candidates, and will be directly responsible for approving the search firm’s fees and other retention terms.

MLAC has not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, the board of directors considers educational background, diversity of professional experience, knowledge of its business, integrity, professional reputation, independence, wisdom, and the ability to represent the best interests of its shareholders. Prior to its initial business combination, holders of MLAC Public Shares will not have the right to recommend director candidates for nomination to the MLAC Board.

Compensation Committee Interlocks and Insider Participation

None of MLAC’s officers currently serves, or in the past year has served, as a member of the compensation committee of any entity that has one or more officers serving on MLAC Board.

Code of Ethics

MLAC has adopted a Code of Ethics applicable to MLAC’s directors, officers and employees. MLAC has filed a copy of its Code of Ethics with the SEC. You may review this document by accessing its public filings at the SEC’s web site at www.sec.gov. In addition, a copy of the Code of Ethics and the charters of the committees of MLAC Board will be provided without charge upon request from MLAC. If MLAC makes any amendments to its Code of Ethics other than technical, administrative or other non-substantive amendments, or grant any waiver, including any implicit waiver, from a provision of the Code of Ethics applicable to its principal executive officer, principal financial officer principal accounting officer or controller or persons performing similar functions requiring disclosure under applicable SEC or Nasdaq rules, MLAC will disclose the nature of such amendment or waiver on its website. The information included on its website is not incorporated by reference into this Form 10-K or in any other report or document MLAC files with the SEC, and any references to its website are intended to be inactive textual references only.

Conflicts of Interest

Under Cayman Islands law, directors and officers owe the following fiduciary duties:

a) duty to act in good faith in what the director or officer believes to be in the best interests of the company as a whole;

b) duty to exercise powers for the purposes for which those powers were conferred and not for a collateral purpose;

c) directors should not improperly fetter the exercise of future discretion;

d) duty to exercise powers fairly as between different sections of shareholders;

e) duty not to put themselves in a position in which there is a conflict between their duty to the company and their personal interests; and

f) duty to exercise independent judgment.

In addition to the above, directors also owe a duty of care which is not fiduciary in nature. This duty has been defined as a requirement to act as a reasonably diligent person having both the general knowledge, skill and experience that may reasonably be expected of a person carrying out the same functions as are carried out by that director in relation to the company and the general knowledge skill and experience of that director.

192

As set out above, directors have a duty not to put themselves in a position of conflict and this includes a duty not to engage in self-dealing, or to otherwise benefit as a result of their position. However, in some instances what would otherwise be a breach of this duty can be forgiven and/or authorized in advance by the shareholders provided that there is full disclosure by the directors. This can be done by way of permission granted in the MLAC Memorandum and Articles or alternatively by shareholder approval at general meetings.

MLAC’s officers and directors presently and in the future may have additional, fiduciary or contractual obligations to another entity pursuant to which such officer or director is or will be required to present a business combination opportunity to such entity. Accordingly, if any of its officers or directors becomes aware of a business combination opportunity which is suitable for an entity to which he or she has then-current fiduciary or contractual obligations, he or she will honor his or her fiduciary or contractual obligations to present such business combination opportunity to such entity, subject to their fiduciary duties under Cayman Islands law. MLAC Memorandum and Articles provides that, to the fullest extent permitted by applicable law: (i) no individual serving as a director or an officer shall have any duty, except and to the extent expressly assumed by contract, to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as MLAC; and (ii) MLAC renounces any interest or expectancy in, or in being offered an opportunity to participate in, any potential transaction or matter which may be a corporate opportunity for any director or officer, on the one hand, and MLAC, on the other. MLAC does not believe, however, that the fiduciary duties or contractual obligations of MLAC’s officers or directors will materially affect its ability to complete its initial business combination.

Below is a table summarizing the entities to which MLAC’s executive officers and directors currently have fiduciary duties or contractual obligations:

Individual	Entity	Entity’s Business	Affiliation/Title

MLAC’S MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

References in this section of this proxy statement/prospectus to MLAC’s “management” or MLAC’s “management team” refer to MLAC’s officers and directors. The following discussion and analysis provides information which MLAC’s management believes is relevant to an assessment and understanding of its results of operations and financial condition. This discussion and analysis should be read together with the sections of the proxy statement/prospectus entitled “Information About MLAC” and MLAC’s financial statements and related notes thereto that are included elsewhere in the proxy statement/prospectus. In addition to historical financial information, this discussion and analysis contains forward-looking statements based upon current expectations that involve risks, uncertainties and assumptions. See the section entitled “Cautionary Note Regarding Forward-Looking Statements.” Actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” or elsewhere in the proxy statement/prospectus.

Overview

MLAC is a blank check company incorporated in the Cayman Islands on June 14, 2024, for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. MLAC is an early stage and emerging growth company and, as such, MLAC is subject to all of the risks associated with early stage and emerging growth companies.

On June 27, 2024, the Sponsor made a capital contribution of $25,000 to cover certain expenses on behalf of MLAC in exchange for issuance of the MLAC Founder Shares. Subsequently, on December 12, 2024, MLAC, through a share capitalization, issued an additional 359,375 MLAC Class B Ordinary Shares to the Sponsor, resulting in an aggregate of 7,546,875 MLAC Class B Ordinary Shares issued and outstanding. The holders of the MLAC Class B Ordinary Shares agreed to forfeit and cancel up to an aggregate of 984,375 MLAC Founder Shares, on a pro rata basis, to the extent that the option to purchase additional MLAC Units is not exercised in full by the underwriters. The forfeiture will be adjusted to the extent that the option to purchase additional MLAC Units is not exercised in full by the underwriters so that the MLAC Class B Ordinary Shares will represent approximately 23.2% of all of MLAC’s issued and outstanding shares after the Initial Public Offering. On December 16, 2024, the underwriters partially exercised their over-allotment option as part of the closing of the Initial Public Offering and forfeited their option to exercise the remaining over-allotment option. As such, 359,375 MLAC Founder Shares were forfeited and resulted in a total number of 7,187,500 MLAC Class B Ordinary Shares outstanding.

On December 16, 2024, MLAC consummated its initial public offering of 23,000,000 MLAC Units. Each MLAC Unit consists of one MLAC Class A Ordinary Share and one MLAC Right, with each MLAC Right entitling the holder thereof to receive one-tenth of one MLAC Class A Ordinary Share upon the consummation of an initial business combination. The MLAC Units were sold at a price of $10.00 per unit, generating gross proceeds to MLAC of $230,000,000. MLAC granted BTIG, the representative of the several underwriters of the MLAC IPO, a 45-day option to purchase up to 3,150,000 additional MLAC Units solely to cover over-allotments, if any. On December 13, 2024, the underwriters partially exercised the over-allotment option to purchase an additional 2,000,000 MLAC Units.

Simultaneously with the closing of the MLAC IPO, MLAC completed the private sale of an aggregate of 805,000 MLAC Private Placement Shares to the Sponsor and BTIG at a purchase price of $10.00 per unit, generating gross proceeds to MLAC of $8,050,000.

Since the MLAC IPO, MLAC’s activity has been limited to the search and evaluation of and negotiation with acquisition targets for its initial business combination.

MLAC has until June 16, 2026 (18 months from the closing of the MLAC IPO), or until such earlier liquidation date as the MLAC Board may approve or such later date as the MLAC Shareholders may approve pursuant to the MLAC Memorandum and Articles, to consummate an initial business combination.

MLAC Units, MLAC Class A Ordinary Shares and MLAC Rights are traded on The Nasdaq Global Market under the symbols “MLACU,” “MLAC” and “MLACR,” respectively. MLAC Units commenced public trading on December 16, 2024, and MLAC Class A Ordinary Shares and MLAC Rights commenced separate trading on February 3, 2025.

Recent Developments

The Business Combination Agreement

On October 1, 2025, MLAC, Pubco, the Pubco Subsidiaries, the Company and Seller entered into the Business Combination Agreement. On January 13, 2026, and on March 17, 2026, MLAC, Pubco, the Pubco Subsidiaries, the Company, Seller Related Parties and Astral entered certain amendments to the Business Combination Agreement, effective as of October 1, 2025.

Astral is a Delaware limited partnership whose general partner is Astral Horizon GP, LLC. The limited partners of Astral are certain senior managers and employees of the Seller and the general partners of the DVs. Astral Horizon GP, LLC is managed by some of the same individuals who serve as the managers of the general partners of the DVs. Accordingly, Astral is a related party to the Seller Related Parties by virtue of common management and overlapping ownership among their respective principals. The Additional Merger Consideration shares are being issued to Astral in consideration for advisory and strategic services provided by Astral’s limited partners in connection with the structuring and execution of the Business Combination and the establishment of Pubco. Such services included, but were not limited to:

(i) Executive Recruitment: Astral’s limited partners assisted in identifying, evaluating, and recruiting the Chief Executive Officer of Pubco; and

(ii) Tax and Corporate Structuring Advisory: Astral’s limited partners provided strategic advice regarding aspects of the tax and corporate structuring of the Business Combination and post-Closing operations of Pubco.

Consequently, (i) on January 13, 2026, the Parties entered into the First Amendment to the Business Combination Agreement, pursuant to which, inter alia, the 4,000,000 Additional Merger Consideration Shares (i.e., the 2,000,000 Astral Post-Closing Shares and the 2,000,000 Astral Earnout Shares) will be issued, on the Company Merger Effective Date, to Astral (the Astral Earnout Shares being held in escrow for the Escrow Period to only be released in accordance with the Astral Escrow Agreement), and (ii) on March 17, 2026, the Parties entered into the Second Amendment to the Business Combination Agreement, pursuant to which the issuance by Pubco to Astral of the 2,000,000 Astral Post-Closing Shares will occur on the thirtieth (30th) calendar day following the Closing Date, rather than on the Company Merger Effective Date.

Pursuant to the Business Combination Agreement, and subject to the terms and conditions set forth therein, (a) prior to the Closing, MLAC will effect the Domestication, pursuant to which MLAC will transfer by way of continuation to and become a Delaware corporation, (b) at least two hours after the Domestication, the MLAC Merger will be completed, pursuant to which MLAC Merger Sub will merge with and into MLAC, with MLAC continuing as the surviving company and a wholly owned subsidiary of Pubco and with MLAC Shareholders receiving one (1) share of Pubco Class A Stock for each MLAC Class A Ordinary Share held by such MLAC Shareholder, and with each holder of MLAC Rights receiving one (1) share of Pubco Class A Stock in exchange for every ten (10) MLAC Rights held by such holder, and (c) the Company Merger will be completed, pursuant to which Company Merger Sub will merge with and into the Company, with the Company continuing as the surviving company, and with (i) each Company Member other than Seller Related Parties receiving one (1) share of Pubco Class A Stock for each Company Unit held immediately prior to the effective time of the Company Merger, (ii) Seller Related Parties receiving one (1) share of Pubco Class A Stock and one (1) share of Pubco Class B Stock for each Company Unit held and (iii) Astral receiving the Additional Merger Consideration Shares, as follows: (i) 2,000,000 shares of Pubco Class A Stock (the “Astral Escrow Shares”) will be issued at the Company Merger Effective Time and deposited into an escrow account with the Trustee (or another escrow agent reasonably acceptable to Seller and Pubco) (the “Astral Escrow Account”), and (ii) 2,000,000 shares of Pubco Class A Stock (the “Astral Post-Closing Shares”) will be issued and deposited into Astral’s security account on the thirtieth (30th) calendar day following the Closing Date.

Business Combination Agreement Amendments

On January 13, 2026, MLAC, Pubco, the Pubco Subsidiaries, the Company, Seller Related Parties and Astral entered into the First Amendment, which amends the Business Combination Agreement, and pursuant to which, among other things, the parties thereto agree that:

(viii) Astral and the DVs were added as parties to the Business Combination Agreement and they agreed to be bound by, and to comply with, the terms and conditions of the Business Combination Agreement, in the same manner as if they were original signatories thereto;

(ix) the Company Units held by the DVs are to be treated as the Company Units held by Seller such that, as a result of the Company Merger, the DVs will receive one (1) Pubco Class A Stock and one (1) Pubco Class B Stock for each Company Unit held by the DVs;

(x) the Additional Merger Consideration Shares to be issued at Closing will (a) be issued to Astral rather than to Seller as provided in the original version of the Business Combination Agreement, and (b) consist of 4,000,000 shares of Pubco Class A Stock only, with no Pubco Class B Stock to be allotted as Additional Consideration because Pubco Class B Stock will be issued to Seller Related Parties;

(xi) the Representations and Warranties of the Seller are to be made severally but not jointly by the Seller Related Parties and Astral rather than solely by Seller as provided in the original version of the Business Combination Agreement;

(xii) certain references to the Seller (as specified in the First Amendment) shall be considered as references to the Seller Related Parties, Astral or the Seller Related Parties and/or Astral, as applicable;

(xiv) The First Amendment is effective as of October 1, 2025.

On March 17, 2026, MLAC, Pubco, the Pubco Subsidiaries, the Company, Seller Related Parties and Astral entered into the Second Amendment, and pursuant to which, among other things, the parties thereto agree to postpone the issuance by Pubco to Astral of the Astral Post-Closing Shares for a period of thirty (30) calendar days, so that such issuance will occur on the thirtieth (30th) calendar day following the Closing Date, rather than on the Company Merger Effective Date. The Second Amendment is effective as of October 1, 2025.

Company Unit Subscription

Concurrently with the execution of the Business Combination Agreement, Pubco, the Company and MLAC entered into the Company Unit Subscription Agreements with the Company Unit Investors, pursuant to which the Company Unit Investors agreed to purchase, payable in cash, USDC or AVAX (or a combination of cash, USDC and/or AVAX), and the Company agreed to issue and sell, approximately $216 million worth of Company Units at the Per Unit Price, upon the terms and subject to the conditions set forth therein. Company Unit Investors received a number of Company Units equal to (a) if the Company Unit Investor elected to purchase Company Units by contributing AVAX, the Stated AVAX Amount multiplied by the Applicable Signing AVAX Price, or (b) if the Company Unit Investor elected to purchase the Company Units by contributing cash or USDC, the Stated Dollar Amount or the Stated USDC Amount (as applicable) divided by the Per Unit Price. For more information about the Company Unit Subscription Agreements, please see the section entitled “The Business Combination Proposal — Other Transaction Agreements — The Company Unit Subscription Agreements.”

Results of Operations

MLAC has neither engaged in any operations nor generated any revenues to date. MLAC’s only activities from June 14, 2024 (inception) through December 31, 2025 were organizational activities, those necessary to prepare for its initial public offering, described below, and identifying a target company for a Business Combination. MLAC does not expect to generate any operating revenues until after the completion of its Business Combination. MLAC generates non-operating income in the form of interest income on marketable securities held in the Trust Account. MLAC may incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

For the year ended December 31, 2025, MLAC had a net income of $8,281,946, which consists of interest income on marketable securities held in the Trust Account of $9,586,719, partially offset by general and administrative expenses of $1,304,773.

For the period from June 14, 2024 (inception) through December 31, 2024, MLAC had a net income of $443,117, which consisted of interest earned on marketable securities held in the Trust Account of $493,853, offset by operating expenses of $50,736.

Liquidity and Capital Resources

On December 16, 2024, MLAC consummated the Initial Public Offering of 23,000,000 Units, which includes the partial exercise by the underwriters of their over-allotment option in the amount of 2,000,000 Units, at $10.00 per Unit, generating gross proceeds of $230,000,000. Simultaneously with the closing of the Initial Public Offering, MLAC consummated the sale of 805,000 MLAC Private Placement Shares at a price of $10.00 per MLAC Private Placement Share in a private placement to the Sponsor, generating gross proceeds of $8,050,000.

Following the Initial Public Offering, the partial exercise of the over-allotment option, and the sale of the Private Units, a total of $231,150,000 was placed in the Trust Account. MLAC incurred $13,354,261, consisting of $4,600,000 of cash underwriting fees, $8,050,000 of deferred underwriting fees and $704,261 of other offering costs.

For the year ended December 31, 2025, net cash used in operating activities was $930,712. Net income of $8,281,946 was affected by interest earned on marketable securities held in Trust Account of $9,586,719. Changes in operating assets and liabilities provided $374,061 of cash from operating activities.

For the period from June 14, 2024 (inception) through December 31, 2024, net cash used in operating activities was $159,847. Net income of $443,117 was offset by interest earned on marketable securities of $493,853, formation cost paid by the Sponsor in exchange for issuance of MLAC Class B Ordinary Shares of $8,533 and payment of formation costs through promissory note of $70,488. Changes in operating assets and liabilities, which used $188,132 of cash from operating activities.

At December 31, 2025, MLAC had cash and marketable securities held in the Trust Account of $241,230,572 (including approximately $10,080,572 of interest income and net of unrealized losses). MLAC intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account, which interest shall be net of taxes payable and excluding deferred underwriting commissions, to complete its Business Combination. MLAC may withdraw interest from the Trust Account to pay taxes, if any. To the extent that its share capital or debt is used, in whole or in part, as consideration to complete a Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue its growth strategies.

At December 31, 2025, MLAC had cash of $452,680 held outside of the Trust Account. MLAC intend to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor and its Affiliates or certain of its officers and directors may, but are not obligated to, loan us funds as may be required. If MLAC completes a Business Combination, MLAC may repay such loaned amounts out of the proceeds of the Trust Account released to us. In the event that a Business Combination does not close, MLAC may use a portion of the working capital held outside the Trust Account

197

to repay such loaned amounts, but no proceeds from the Trust Account would be used for such repayment. Up to $1.5 million of such MLAC Working Capital Loans may be converted into units of the post Business Combination entity at a price of $10.00 per Unit. The units would be identical to the MLAC Private Placement Shares.

In connection with MLAC’s assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Presentation of Financial Statements-Going Concern”, as of December 31, 2025, MLAC lacks the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the date of the issuance of the financial statements. MLAC cannot ensure that its plans to raise capital or to consummate an initial Business Combination will be successful. In addition, MLAC’s management has determined that if MLAC is unable to complete an initial Business Combination within the Combination Period, then MLAC will cease all operations except for the purpose of liquidating. These conditions raise substantial doubt about MLAC’s ability to continue as a going concern. MLAC’s management plans to consummate an initial Business Combination prior to the mandatory liquidation date. No adjustments have been made to the carrying amounts of assets or liabilities should MLAC be required to liquidate after June 16, 2026.

Off-Balance Sheet Financing Arrangements

MLAC has no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of December 31, 2025. MLAC does not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. MLAC has not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

Contractual Obligations

MLAC does not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement to pay the Chairman and Chief Executive Officer and the President and Chief Financial Officer, a total of up to $20,000 per month for their services as executive officers and directors of MLAC. For the year ended December 31, 2025, MLAC incurred and paid an expense of $240,000 of fees for these services. For the period from June 14, 2024 (inception) through December 31, 2024, no fees were incurred for these services.

The underwriters are entitled to a deferred underwriting fee of $0.35 per Unit, or $8,050,000 in the aggregate. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that MLAC completes a Business Combination, subject to the terms of the underwriting agreement.

On October 1, 2025, MLAC amended the Underwriting Agreement which shall apply only in connection with the Business Combination and shall not apply in connection with any Business Combination that may be contemplated or consummated between MLAC and any party other than AVAT Parties or its affiliates. The parties agree that if the Business Combination is terminated for any reason, this amendment to the underwriting agreement shall be void and of no effect for all purposes. As a result of such amendment, MLAC owes only $1,000,000 to the underwriters if the Business Combination is consummated.

Sponsor Support Agreement

Concurrently with the execution of the Business Combination Agreement, MLAC, Sponsor and Pubco entered into the Sponsor Support Agreement, pursuant to which, among other things, the Sponsor agreed (i) to vote its MLAC Ordinary Shares in favor of the Business Combination Agreement and the Transactions and each of the MLAC Shareholder Approval Matters, (ii) to vote its MLAC Ordinary Shares against (a) any Acquisition Proposal, (b) any merger, consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by MLAC (other than the Transactions), (c) any change in the business of MLAC and (d) any proposal, action or agreement involving MLAC that would or would reasonably be expected to jeopardize the Transactions, (iii) to comply with the restrictions imposed by the Insider Letter, including the restrictions on transfer and redemption of MLAC Ordinary Shares in connection with the Transactions, (iv) subject to and conditioned upon the consummation of the MLAC Merger, to waive any anti-dilution rights that would otherwise result in the MLAC Class B Ordinary Shares held by Sponsor converting into MLAC Class A Ordinary Shares on a greater than one-for-one basis, (v) to deliver to MLAC for cancellation 495,000 MLAC Private Placement Shares and 4,387,500 MLAC Founder Shares immediately prior to the MLAC Merger Effective Time, (vi) to effect certain security cancellations and deposit certain Pubco Class A Stock issued to it at Closing into

198

escrow in connection with the Closing and (vii), subject to and effective as of the Closing, to irrevocably and unconditionally release and waive any and all claims it may have against MLAC, Pubco and the Company or their respective Affiliates arising on or prior to the Closing, subject to customary carve-outs.

Further, pursuant to the Sponsor Support Agreement, the parties agreed that prior to the Closing they would enter into an amendment to the Insider Letter, to amend certain terms relating to transfer restrictions applicable to the shares held by the Sponsor.

For more information about the Sponsor Support Agreement, please see the section entitled “The Business Combination Proposal — Other Transaction Agreements — Sponsor Support Agreement.”

Critical Accounting Policies and Estimates

The preparation of condensed financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. MLAC has identified the following critical accounting policies.

Class A Ordinary Shares Subject to Possible Redemption

The Public Shares contain a redemption feature which allows for the redemption of such Public Shares in connection with MLAC’s liquidation, or if there is a shareholder vote or tender offer in connection with MLAC’s initial Business Combination. In accordance with ASC 480-10-S99, MLAC classifies Public Shares subject to redemption outside of permanent equity as the redemption provisions are not solely within the control of MLAC. MLAC recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, MLAC recognized the accretion from initial book value to redemption value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit.

Recent Accounting Pronouncements

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on its condensed financial statements.

INFORMATION RELATED TO AVAT

Unless otherwise indicated or the context otherwise requires, references in this section of the proxy statement/prospectus to “AVAT,” “we,” “us,” “our” and other similar terms refer to Avalanche Treasury Company LLC prior to the Business Combination and Avalanche Treasury Corporation (“Pubco”) and its consolidated subsidiaries after giving effect to the Business Combination.

Overview

AVAT is a newly formed operating company focused exclusively on business lines relating to Avalanche and AVAX.

Our strategy is to offer public-market investors a differentiated, capital-efficient way to gain exposure to Avalanche and AVAX through (i) the targeted accumulation of AVAX; (ii) tailored treasury management geared towards staking yield and other asset management levers intended to compound AVAX per share over time and (iii) the further ecosystem integration including the potential provision of Avalanche-focused infrastructure, such as the operation of validator nodes, L1 activation and other corporate development activities, that we believe will expand our exposure to Avalanche.

AVAT was formed in Delaware as a limited liability company on August 20, 2025.

Our Business Strategy

Following the Closing, AVAT intends to execute its strategy in order to support long-term AVAX accumulation, disciplined treasury management and integration with the Avalanche ecosystem.

AVAX Accumulation at Scale

As a publicly listed operating company at Closing, AVAT aims to broaden access to AVAX for a wide range of public-market investors with diverse objectives and risk profiles by opportunistically offering a range of capital raising instruments that present varying degrees of Avalanche and AVAX exposure.

AVAT intends to accumulate AVAX over time through a blended offering of equity and debt instruments, which may be subscribed with cash or AVAX, as well as the deployment of non-AVAX offering proceeds to acquire additional AVAX in the market. Such offerings and acquisitions will be strategically considered and paced based on market conditions and other factors, including (i) market price of AVAX and related trends, (ii) macroeconomic factors, (iii) market appetite and demand and (vi) the Pubco Class A Stock price, including such price relative to the net asset value of its AVAX holdings.

AVAT does not currently intend to hold any other cryptocurrencies as its main treasury asset, however it may, in the execution of its strategy, periodically hold other digital assets.

AVAT retains the flexibility to sell AVAX under certain circumstances, such as to meet operational needs, comply with legal or regulatory obligations, pursue certain investment strategies or for general corporate purposes.

In addition, where the Pubco Class A Stock trades at a meaningful discount to our estimated mNAV relative to the prevailing AVAX price (as reported by Coinbase or another leading digital asset trading platform), we may sell a portion of our AVAX to fund opportunistic share repurchases. We believe this disciplined capital-allocation approach — dynamically arbitraging the relationship between our share price, implied premium/discount to mNAV and the AVAX price — can be accretive to mNAV per share and align with long-term shareholder value. Any such activity would be subject to applicable law, our liquidity and risk parameters, market conditions, internal Board and relevant committee authorization, and there can be no assurance that any repurchases will be undertaken.

AVAT does not currently plan to engage in hedging its AVAX exposure. AVAT retains the option to revisit its AVAX accumulation strategy or any related policies periodically as part of its ongoing strategic review and risk management.

200

Active AVAX Treasury Management

AVAT’s active AVAX treasury management strategy will initially target (i) the staking of AVAX and (ii) the deployment of AVAX to traders, market makers, asset managers and other crypto market participants to with the goal of adopting conservative yield approaches, for example through spreading out of the validation process across multiple independent validator nodes, thereby lowering risk by reducing reliance on any single party, and the use of established and reliable DeFi platforms, which are blockchain-based financial services that do not depend on traditional intermediaries, to further reduce risk and improve liquidity, focused on preservation and consistent returns, in each case subject to market conditions and other factors, intended to generate AVAX for treasury growth or the payment of operating expenses. AVAT currently engages in staking via third-party node operators as part of its active treasury management strategy. For the period from August 20, 2025 (inception) through December 31, 2025, the Company staked to 13 validator nodes. As of May 4, 2026, the Company staked to 8 validator nodes.

To optimize staking returns while mitigating risks, we intend to carefully monitor our staking operations. This begins with the selection and oversight of trusted third-party staking providers, and extends to ongoing operational involvement. For example, we intend to conduct independent monitoring of validator performance alongside periodic reports provided by our staking service providers and to reinvest accrued staking rewards into the establishment of additional validators, where practicable. Management’s AVAX staking strategy does not include any fixed delegation or staking percentages or allocations, and is generally designed to preserve management’s flexibility and business judgment in deploying AVAX and adapting to rapidly changing, fluid market conditions. For example, business judgment may include the consideration that longer staking durations can amount to less liquidity — in periods where greater liquidity is desired, management may elect to pursue exclusively shorter staking durations.

In addition to traditional staking, the Company pursues and intends to continue pursuing liquid staking opportunities. We believe that liquid staking is value additive as it provides the opportunity to receive liquid staking tokens in return for the deposit of AVAX into a locked protocol (preserving partial asset liquidity).

The Avalanche liquid staking market consists of several protocols that issue liquid staking tokens in exchange for staked AVAX. As of May 4, 2023, liquid staking tokens relating to AVAX represented approximately 6% of the total outstanding supply of AVAX, which, with AVAX’s approximate market capitalization of $4.3 billion as of May 5, 2026, would amount to approximately $250 million of the total market capitalization of AVAX. The dominant protocol is BENQI Protocol, which issues sAVAX and accounts for approximately 85% of the Avalanche liquid staking market. The Hypha Protocol is the second-largest liquid staking protocol on the Avalanche, which issues stAVAX. The Avalanche liquid staking market remains relatively small compared to the broader global liquid staking market, which totals approximately $42 billion across all blockchain networks. Other Avalanche liquid staking tokens include ankrAVAX issued by Ankr and yyAVAX issued by Yield Yak, though these represent smaller portions of the market.

AVAT currently holds stAVAX and sAVAX as liquid staking tokens. The Company currently intends to continue holding these tokens primarily for yield generation, while also benefiting from their more flexible liquidity profiles relative to traditionally staked AVAX, which cannot be accessed or redeployed during the applicable staking period. Unlike traditionally staked AVAX, stAVAX and sAVAX remain transferable and can generally be used as acceptable collateral with lenders, which the Company believes enhances its optionality, liquidity management and operational flexibility. The Company does not currently intend to convert or dispose of its stAVAX or sAVAX holdings, though it may do so in the future if market conditions or strategic considerations warrant such action. From a liquidity perspective, the Company believes that holding liquid staking tokens rather than traditionally staked AVAX reduces the risk of illiquidity during periods of market volatility, as management can more readily react to changing conditions without being subject to fixed unstaking periods. With respect to valuation, the Company values its stAVAX and sAVAX holdings based on the prevailing market prices for such tokens, which generally reflect the value of the underlying staked AVAX plus any accrued staking rewards, subject to market-driven premiums or discounts. The Company monitors these valuations on an ongoing basis as part of its active AVAX treasury management strategy. The Company does not currently intend to otherwise deploy its stAVAX or sAVAX, though it may do so in the future in line with its active AVAX treasury management strategy.

stAVAX is a liquid staking token issued on the Avalanche C-Chain by the decentralized liquid staking and validator infrastructure protocol known as the Hypha Protocol (formerly known as GoGoPool). When users deposit AVAX into the Hypha Protocol, they receive stAVAX in return. The deposited AVAX is pooled to form Avalanche validator nodes, each requiring 2,000 AVAX. stAVAX is a reward-bearing token: its exchange rate relative to AVAX increases over time based on the ratio of total AVAX staked (including accrued rewards) to total stAVAX minted. stAVAX has an elastic mint-and-burn supply model; tokens are minted when users stake AVAX and burned when users unstake and redeem AVAX.

201

sAVAX is a liquid staking token issued on the Avalanche C-Chain by the BENQI Protocol. When users deposit AVAX into the BENQI protocol, they receive sAVAX in return. The deposited AVAX is then delegated to validator nodes on the Avalanche P-Chain. sAVAX is a reward-bearing token; its exchange rate relative to AVAX increases over time based on the ratio of total AVAX staked (including accrued rewards) to total sAVAX minted. sAVAX has an elastic, mint-and-burn supply model: tokens are minted when users stake AVAX and burned when users unstake and redeem AVAX.

Both stAVAX and sAVAX are ERC-20 compatible tokens on the Avalanche C-Chain. Both tokens can be freely transferred, traded on decentralized exchanges, or used as collateral and in other decentralized finance applications, such as lending and borrowing protocols, liquidity pools and yield farming strategies, providing holders with liquidity that would not be available through traditional, direct AVAX staking on the P-Chain. The Company currently does not utilize stAVAX or sAVAX in this capacity.

The Hypha Protocol does not charge delegation fees or hardware fees to liquid stakers, but charges a protocol fee equal to 10% of the total staking yields generated, which is deducted before rewards accrue to stAVAX holders. Reported yields for stAVAX have generally been in the range of approximately 5–7% annual percentage yield (“APY”), though yields fluctuate based on network conditions, validator performance and the proportion of AVAX actively deployed in minipools versus idle in the liquidity pool.

The BENQI Protocol does not charge fees for staking, depositing or withdrawing AVAX from its liquid staking protocol. The BENQI Protocol retains 10% of the total staking yields generated, which is deducted before rewards accrued to sAVAX holders, meaning it is reflected as a lower return rather than a fee charged later. The current staking APY for sAVAX is approximately 4.8–5.4%, though the rate fluctuates based on the overall amount of AVAX staked across the Avalanche network and validator performance. No lock-up period is required when initially staking AVAX.

The yields on both tokens are variable, not fixed, and are subject to change based on factors including the total amount of AVAX staked network-wide, validator uptime and performance, network inflation parameters and the protocols’ respective fee structures. Neither protocol guarantees any particular rate of return.

stAVAX holders may redeem their tokens for AVAX by unstaking directly through the Hypha Protocol, subject to the availability of AVAX liquidity in the deposit pool and in accordance with the protocol documents. The redemption process involves permanently removing or “ burning” the stAVAX and returning the equivalent amount of AVAX (including accumulated rewards) to the user at the then-current exchange rate. If there is insufficient liquidity in the pool to fulfill the redemption, users may have to wait up to 15 days for the staked underlying AVAX to unstake and become available. Holders may alternatively swap stAVAX for AVAX on decentralized exchanges at prevailing market rates. There is no mandatory cooldown period for redemptions from the pool when liquidity is available, though underlying Avalanche validation cycles operate on approximately 15-day periods.

sAVAX holders may redeem their tokens for AVAX by unstaking directly through the BENQI Protocol, subject to a 15 day cooldown (unlock) period and in accordance with the protocol documents. The redemption process involves burning the sAVAX and returning the equivalent amount of AVAX (including accumulated rewards) to the user at the relevant exchange rate. Alternatively, holders seeking immediate liquidity may swap sAVAX for AVAX on decentralized exchanges at prevailing market rates.

stAVAX has an elastic supply, mint-and-burn supply model. As of May 4, 2026, the total minted and outstanding supply of stAVAX was approximately 1.35 million tokens (though sources vary depending on whether circulating or total on-chain supply is measured) and the price of stAVAX was in the range of $10.74 to $11.45, as compared to an outstanding supply of approximately 463 million AVAX. As of May 4, 2026 the Company held 575,123 stAVAX, or approximately 42% of the outstanding supply.

sAVAX also has an elastic, mint-and-burn supply model. As of May 4, 2026, the circulating supply of sAVAX was approximately 20 – 23 million tokens and the price of sAVAX was in the range of $11.35 to $12.25, as compared to an outstanding supply of approximately 463 million AVAX. As of May 4, 2026 the Company holds 2,354,568 sAVAX, or approximately 10% of the outstanding supply.

The valuations of stAVAX and sAVAX are each directly correlated to the price of the underlying AVAX token. Because each liquid staking token represents a claim on staked AVAX plus accrued rewards, their prices generally track the price of AVAX, with the exchange rate (i.e., the number of AVAX redeemable per liquid staking token) increasing over time as staking rewards accumulate. However, on secondary markets, sAVAX and stAVAX may trade at a slight discount to their theoretical exchange rate due to reduced liquidity relative to AVAX, additional smart contract risk, and the existence of cooldown or redemption periods.

202

The Hypha Protocol (formerly GoGoPool or GGP) is governed by holders of the GGP governance token through the GoGoPool protocol DAO. GGP governance token holders may propose and vote on governance matters, including the GGP token inflation schedule, reward distributions between minipool operators and the DAO, configuration of minimum and maximum staking amounts and smart contract upgrades. The protocol DAO maintains a treasury to fund security audits and community contributions. The Hypha Protocol also employs an oracle DAO that works alongside the protocol DAO to maintain decentralized protocol operations. Validator selection within the Hypha Protocol is facilitated through the “minipool” architecture: minipool operators stake their own AVAX and GGP collateral (at least 10% of the borrowed AVAX amount) and are matched with pooled AVAX from liquid stakers to form validator nodes.

The BENQI Protocol is governed by holders of the QI governance token (“QI”). QI holders may vote on BENQI Protocol improvement proposals, which direct changes to the protocol’s parameters, fee structures and supported assets. The BENQI Protocol founding team initially retained control over governance but has publicly stated plans for a full transition to DAO governance. The BENQI Protocol also operates a “Node Voting” system: holders of BENQI miles tokens (earned by staking QI) may vote to influence how AVAX from the BENQI liquid staking pool is delegated to specific Avalanche validators, thereby influencing validator selection and promoting network decentralization. The BENQI Protocol distributes staked AVAX across multiple validators to mitigate concentration risk.

sAVAX is primarily traded on decentralized exchanges on the Avalanche C-Chain, including Trader Joe (LFJ) and Pangolin. stAVAX is similarly traded primarily on decentralized exchanges, such as Pharaoh Exchange and Balancer V3.

As of December 31, 2025, the Company held 1,180,516 stAVAX tokens, which were valued at $15,246,914 as of such date, and did not hold any sAVAX. The Company deposited 1,352,876 AVAX tokens to receive the 1,180,516 stAVAX tokens.

As of May 4, 2026, the Company held 2,354,568 sAVAX and 575,123 stAVAX, which were collectively valued at $33,170,597 as of such date. The Company deposited 3,623,584 AVAX tokens to receive the 2,354,568 sAVAX and 575,123 stAVAX. As of May 4, 2026 the Company held approximately 42% of the outstanding supply of stAVAX and approximately 10% of the outstanding supply of sAVAX. See “Risk Factors — Risks Related to the Business and Strategy of Pubco — Pubco will face risks associated with the concentration of its holdings of stAVAX and sAVAX.” The Company not currently plan to convert its AVAX into liquid staking tokens other than sAVAX and stAVAX. As of May 4, 2026, the Company held 4,489,918 staked AVAX and 7,229,297 unstaked AVAX that was not converted into liquid staking tokens. See “Risk Factors — Risks Related to the Business and Strategy of Pubco — Pubco will face risks associated with AVAX delegation, staking, liquid staking and associated lock-ups.”

Like our staking strategy, our liquid staking strategy does not include any fixed delegation or staking percentages or allocations, and is generally designed to preserve management’s flexibility and business judgment in deploying AVAX and adapting to rapidly changing, fluid market conditions. Like traditional staking methods, staking rewards earned from liquid staking are not guaranteed, reward rates are subject to fluctuation and liquid staked tokens face the same staking mechanism risks as traditionally staked tokens. These practices are intended to support compounding yield, safeguard validator performance and promote transparency throughout our AVAX staking process.

Determinations with respect to our AVAX management strategy, particularly with regards to the deployment of AVAX, other digital assets or fiat to traders, market makers, asset managers and other crypto market participants to execute any of our trading or yield strategies, will be made from time to time by assessing market factors including, but not limited to, (i) the current market price of AVAX, (ii) price trends and market level analysis, (iii) analysis of the broader macroeconomic environment and (iv) AVAT’s relative stock performance.

In pursuit of this strategy, we may utilize AVAX-specific key performance indicators including AVAX reserves per share to assess our performance and guide our operations. These KPIs are intended to efficiently communicate AVAT’s mission of providing the best vehicle for secure, transparent and yield-generating exposure to AVAX at institutional scale.

This strategy also contemplates that AVAT may, from time to time, subject to market conditions and other factors, (i) sell AVAX for general corporate purposes or in furtherance of strategies that AVAT believes are accretive to shareholders, (ii) enter into additional capital raising transactions and (iii) consider the pursuit of strategies that monetize or otherwise utilize its AVAX holdings to generate funds or income streams through the development and commercialization of new AVAX-based smart contracts and decentralized applications (“dApps”) for services and products.

203

Avalanche Technology and Ecosystem Partner

In addition to aiming to deliver secure, transparent and yield-generating exposure to AVAX at an institutional scale, AVAT may pursue a range of additional Avalanche-related business activities. After the Closing, we intend to evaluate opportunities to operate our own validator nodes independent of third-party providers to consolidate our staking efforts. We also plan to actively support and engage with Avalanche-native projects via potential ecosystem partnerships with enterprises, asset managers and other participants, and also via early participation in emergent protocols and L1s.

Validator node operations. After the Closing, AVAT intends to evaluate opportunities to operate its own validator nodes, independent of third-party service providers. This may allow us to consolidate our staking efforts and contribute towards the security and efficiency of the Avalanche Network. By running our own validator nodes independent of third-party service providers, we can directly participate in the Avalanche Network’s consensus mechanism, thereby enhancing our control over staking operations and optimizing yield generation.

Ecosystem partnerships and engagement. We plan to actively support and engage with Avalanche-native projects through potential ecosystem partnerships. This includes collaborating with enterprises, asset managers and other participants in the Avalanche Network. By forming strategic alliances, we believe we can foster innovation and growth within the Avalanche ecosystem. Our engagement may involve early participation in emergent protocols and L1 solutions as they arise.

On-chain opportunities and infrastructure solutions. We may pursue on-chain opportunities that offer attractive risk-adjusted returns. This may include developing and offering infrastructure solutions tailored to the needs of Avalanche-native builders, as well as providing staking solutions for enterprises and funds seeking to generate AVAX-denominated revenue. We may also provide infrastructure solutions for a variety of stakeholders, including enterprises, decentralized autonomous organizations and Avalanche-native builders. These solutions may facilitate seamless access to the Avalanche Network’s consensus and blockspace economy or include comprehensive support for deploying and managing blockchain infrastructure.

Community engagement and education. To further strengthen our position within the Avalanche ecosystem, we may engage in community-building activities and educational initiatives. We may organize and participate in events, workshops or webinars to share knowledge and foster collaboration among Avalanche Network stakeholders. By promoting awareness and understanding of the Avalanche Network’s capabilities and potential, we believe we can foster broader adoption and support for Avalanche.

We intend to leverage the expertise of our Advisory Board in pursuing the foregoing Avalanche-adjacent projects. Given the current volatility in AVAX and digital assets generally, however, the Company is currently unable to reliably estimate any prospective costs and sources of capital for such projects.

The development and launch of any such activities would also require significant organizational, operational and regulatory preparation. These initiatives are subject to various legal and compliance considerations, including oversight by the SEC, the CFTC, FinCEN and state-level regulators such as those in Delaware, as well as compliance with applicable anti-money laundering and other financial laws. Planning for these potential activities is expected to begin following the consummation of the Business Combination; however, there can be no assurance as to the timing or outcome of any such efforts.

Potential Growth Avenues

We intend to pursue both organic and inorganic avenues of growth: (i) organically by expanding our talent base, potential product offering and partnerships, and (ii) inorganically through selective minority investments, joint ventures and acquisitions where we believe such transactions have the potential to accelerate the expansion of our Avalanche-related capabilities and AVAX accumulation. Our leadership team is deeply connected across traditional finance, the Avalanche ecosystem and broader technology networks — a combination we believe is distinctive — and we expect these relationships to provide access to sensible, appropriately structured opportunities over time. Any such initiatives will be undertaken prudently within our governance and risk frameworks and will remain subject to uncertainties and customary conditions, including market conditions, availability of financing and liquidity, valuation, counterparty and regulatory due diligence and required approvals. There can be no assurance that any particular opportunity will be available on acceptable terms or consummated at all. Please see “Risk Factors — Risks Related to the Business and Strategy of Pubco — Pubco may seek to grow its business through minority investments, joint ventures and acquisitions, which could divert

204

management’s attention and otherwise disrupt operations and harm operating results. Pubco may fail to acquire or invest in companies whose market power or technology could be important to the future success of its business” for further details.

Our Competitive Strengths

AVAT believes it is well-positioned to become a leading public market vehicle for investors seeking exposure to AVAX and to compete effectively in the emerging market for AVAX-focused and other digital asset treasury companies.

Exclusive relationship with the Foundation, initial access to discounted supply. AVAT launched with an initial purchase from the Foundation of $200 million worth of AVAX at a 60% discount, along with an 18-month exclusivity term on any Foundation AVAX sales to U.S. digital asset treasury companies and a right of first refusal on certain subsequent discounted sales. We believe this initial contribution and exclusive relationship with the Foundation has provided us with an attractive mNAV at launch and can in the future enhance sourcing flexibility and reduce frictions relating to subsequent acquisitions of AVAX.

Foundational scale and alignment through significant founder contribution. At inception, our founding group, the Seller and Related Parties, agreed to contribute 1,960,040 AVAX, establishing a large, aligned balance-sheet position from day one. We believe this contribution also underscores our founding group’s long-term alignment and commitment to AVAT.

Experienced leadership at the intersection of AVAX and institutional capital and aligned with the Foundation. Our Advisory Board includes Ava Labs founder Emin Gün Sirer, managing partner of Dragonfly Haseeb Qureshi, Blockworks Inc. Chief Executive Officer Jason Yanowitz and Aave Labs Chief Executive Officer Stani Kulechov, which we believe helps differentiate AVAT from ETFs and passive wrappers by providing us with strategically aligned advice from key Avalanche ecosystem participants. Our broader senior team blends foundational cryptography and Avalanche protocol expertise with multi-decade institutional investing experience. For example, Gerald Bartholomew Smith, our Chief Executive Officer, anchors a management group with deep credibility across both technology and finance and provides over 20 years of experience across digital assets, proprietary trading, asset management, market making and institutional capital markets at Susquehanna, AllianceBernstein and UBS.

Public-company platform for institutional adoption, broadening investor access. By operating as a listed company upon Closing, we aim to offer investors multiple forms of exposure to AVAX through listed and potentially unlisted securities and structured instruments calibrated to different risk profiles, potentially expanding our addressable investor base beyond Avalanche-native channels.

A clear operating model built for disciplined AVAX accumulation, active treasury management and structured ecosystem integration. We believe our clear operating model, which is designed to support long-term AVAX accumulation, disciplined treasury growth and further alignment with Avalanche-related infrastructure, and lean approach to operations will allow us to efficiently execute our strategy.

Capability to help shape Avalanche-native capital markets. Beyond holding AVAX, we may participate in the development of Avalanche-native yield, credit and structured-product markets (e.g., AVAX-denominated financing solutions). We believe this broader integration with the Avalanche ecosystem, coupled with our unique relationship with the Foundation, can provide us with the capabilities to shape the Avalanche-native capital markets and entrench our positioning as the premier Avalanche treasury vehicle.

Overview of the Avalanche Industry and Market

AVAX is a digital asset that is issued by and transmitted through an open-source cryptographic computer-code based logic, or protocol, known as the Avalanche Consensus protocol, collectively maintained by a peer-to-peer network of decentralized user nodes. This network hosts a public transaction ledger, known as the Avalanche blockchain, on which AVAX holdings and all validated transactions that have ever taken place on the Avalanche Network are recorded. Balances of AVAX are stored in individual “wallet” functions, which associate network public addresses with one or more “private keys” that control the transfer of AVAX. The Avalanche blockchain can be updated without any single entity owning or operating the network.

205

Overview of the Avalanche Network and Market

Avalanche is an open-source platform for launching decentralized finance applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem. Avalanche uses proof-of-stake, which is designed to support tens of thousands of validators to have a first-hand say in the system while consuming minimal energy. As of May 4, 2026, the Avalanche Network disclosed that 652 validators were in operation on the Primary Network with the requisite minimum amount of staked AVAX.

Unlike legacy blockchain networks, which have only one blockchain and one validator set, Avalanche is a heterogeneous network of many blockchains and validator sets. Avalanche was the first blockchain network to use a new family of consensus protocols created by distributed systems researchers at Cornell University in 2018.

The Avalanche Network allows developers to build and run a variety of applications, all of which run on “smart contracts.” Smart contracts are general-purpose code that execute on every computer in the Avalanche Network, and can be programmed to transmit information and value based on a logical, modular and composable set of logical conditions.

Just as Ethereum allows users to launch a decentralized application defined by a smart contract, Avalanche allows users to launch a decentralized application defined by a Virtual Machine, a virtual computer that defines a blockchain’s complete application logic by specifying the blockchain’s state, state transitions, transaction rules and API interface. Unlike Ethereum, each dApp on Avalanche can choose to run on the Primary Network or on its own independent blockchain. Each such blockchain is validated by a dynamic, custom set of validators. This allows for the creation of custom blockchains, including public or private blockchains.

Avalanche is designed for high-throughput, low-latency smart contract execution, with AVAX as its native token powering core network functions. AVAX is used to pay transaction fees secure the network through staking by validators and delegators, support governance participation, and fund the creation and operation of custom blockchains known as L1s. The Avalanche Network supports a wide range of use cases, including decentralized finance, gaming and consumer applications benefiting from fast finality and low fees, tokenized real-world assets, NFTs and enterprise blockchain solutions.

Network activity includes hundreds of thousands of daily transactions and developer activity is substantial, with several hundred developers contributing annually across core protocol development and ecosystem projects.

As of May 5, 2026, the outstanding supply of AVAX was approximately 463 million with a market capitalization of approximately $4.3 billion and a trading volume over the prior 24-hour period of approximately $44 million. Also as of May 5, 2026, gas fees on Avalanche were $0.00020 for a fast transaction, $0.00020 for a standard transaction, or $0.00019 for a slow transaction. These represent the “gas price” or amount a user must be willing to pay for each unit of gas. Gas is the unit of measurement for the computational effort required to execute a transaction on the Avalanche blockchain. Transactions on Avalanche are submitted with a gas limit, which denotes the maximum units of gas that a particular transaction is allowed to consume. The fast, average and slow gas prices are estimates of how much a user will need to pay to get a transaction processed quickly. The higher the gas price, the faster the transaction will be processed. However, higher gas prices also mean more in fees. If the total gas in the last few blocks of the window is more, less or the same than the target gas, then the base price will increase, decrease or remain the same, respectively.

Unlike other staked assets, such as Ethereum, AVAX doesn’t have a protocol-level unstaking or unbonding period. Instead, it has a minimum staking period ranging from two weeks to one year, meaning staked AVAX tokens can be “locked” for varying periods of time but do not have an unstaking period. Delegation allows AVAX token holders who do not wish to run their own validator node to still participate in staking by “delegating” their tokens to an existing validator node. Both validators and delegators can earn rewards, but validators have higher stakes and more direct involvement in the Avalanche network. Delegators are rewarded according to the same function as validators. However, as long as the validator is online for 90% (previously 80%) of the delegation period, the validator that a user delegates to keeps a portion of the reward specified by the validator’s delegation fee rate. Validators can select AVAX staking periods ranging from two weeks to one year, with the yield scaling linearly between these two bounds with higher annual percentage yield the longer the staking period (with AVAX staked for a year receiving the maximum). As of May 5, 2026, staking rewards for AVAX stood at approximately 6.7% annual percentage yield for AVAX staked for a year. Rewards are automatically distributed only after the chosen period ends.

Avalanche is not just a platform for creating custom dApps. It also has native support for creating and trading smart digital assets. This allows users to get the functionality they want and to comply with regulations.

206

Avalanche permanently finalizes transactions in a few seconds, making Avalanche suitable for real-time payments. Avalanche can be used to achieve consensus on not only linear blockchains but also on blockchains that are Directed Acyclic Graphs (“DAGs”), or graphs in which nodes are linked by one-way connections that do not form any closed loops.

Avalanche is powered by the Avalanche Consensus protocol. For specific use-cases on Avalanche, the platform is made to be totally-ordered and linear; this totally-ordered protocol is known as the Snowman Consensus protocol.

AVAX is a digital asset that is created and transmitted through the operations of the Avalanche peer-to-peer networks and associated blockchain ledgers and a network of computers that operate on the Avalanche Consensus protocol. AVAX allows Avalanche users to interact with smart contracts to send, receive or store value. The Avalanche blockchain is open source by design, meaning any user or developer can interact with, build on, or deploy to the network.

AVAX is capped at a supply of 720 million AVAX. A fixed amount of 360 million AVAX was minted at the outset, but a small amount of AVAX is constantly minted as a reward to validators at the end of their staking period, a process which in-turn offsets the AVAX burned by transaction fees. While AVAX is still far away from its 720 million supply cap, it will almost always remain an inflationary asset. Unlike Ethereum, Avalanche does not take away any portion of a validator’s already staked tokens (commonly known as “slashing”) for negligent or malicious staking periods, however this behavior is disincentivized as validators who attempt to do harm to the network would expend their node’s computing resources for no reward.

Avalanche was designed to be customizable, scalable and interoperable. Validators are required to be a member of the Primary Network. The Primary Network contains three blockchains:

• Platform Chain (P-Chain): The Platform Chain is the metadata blockchain on Avalanche and coordinates validators, staking, keeps track of active L1s and enables the creation of new L1s.

• Contract Chain (C-Chain): The Contract Chain is the blockchain specifically designed for running smart contracts that are compatible with the Ethereum Virtual Machine (“EVM”), which allows developers to migrate their existing dApps to the Avalanche platform. The Contract Chain is optimized for applications that require total ordering, which ensures that transactions are processed in a specific sequence, which can be important for applications like financial transactions or any other use case where the order of operations matters.

• Exchange Chain (X-Chain): The X-Chain serves as the default asset blockchain on Avalanche and is designed for specific purposes, such as creating new assets (i.e., tokens), facilitating asset exchanges without the need for an intermediary and enabling cross-chain transfers between different L1s and within the Avalanche Network. The X-Chain is designed for applications that do not require total ordering of transactions.

History of Avalanche

In May 2018, Team Rocket — a pseudonymous group of software developers — published an article titled “Snowflake to Avalanche: A Novel Metastable Consensus Protocol Family for Cryptocurrencies” that detailed the basis for the Avalanche protocol. Specifically, the article proposed a new family of consensus protocols — Snowflake, Snowball, and Avalanche — that introduced metastability (a probabilistic way to achieve consensus through repeated random sampling), high throughput (thousands of TPS), low latency (1 – 2 second finality) and scalability without proof-of-work. This was novel because it avoided both the energy cost of proof-of-work (like Bitcoin) and the communication overhead of traditional Byzantine fault tolerance (like early proof-of-stake designs).

Soon afterwards, Emin Gün Sirer founded AVA Labs with the goal of creating and developing the protocol for the Avalanche blockchain. The Avalanche mainnet was launched in September 2020.

Smart Contracts and dApps

Smart contracts on the Avalanche Network are self-executing computer programs that run as written by the developer(s) who deploy them. Once deployed, a smart contract operates automatically according to its pre-defined code and cannot generally be modified or deleted. Users interact with smart contracts by submitting transactions that invoke specific functions encoded within the contract. These interactions are recorded on the Avalanche blockchain and are irreversible once confirmed. Execution of smart

207

contract transactions typically requires the payment of a transaction, or “gas,” fee, which is denominated in AVAX. Smart contracts form the basis for most functionality on Avalanche, including the creation and transfer of digital assets, the establishment of decentralized marketplaces, and other on-chain applications.

dApps are applications built on a decentralized network such as Avalanche and typically combine one or more smart contracts with a user interface that allows individuals to interact with those contracts. Unlike traditional applications that rely on centralized servers, dApps execute logic through smart contracts recorded on-chain. As a result, their operation depends on the continued functionality and security of the Avalanche Network rather than a single centralized operator.

Avalanche L1s

On the Avalanche Network, a “Layer 1” or “L1” refers to a dynamic set of validators that collectively achieve consensus on the state of one or more blockchains. Any validator can, but is not required to, validate any L1. Validators may participate in multiple L1s simultaneously.

Each L1 manages its own validator membership and may specify requirements that must be satisfied for participation. For example, an L1 may require that validators be domiciled within a particular jurisdiction, satisfy KYC or AML checks, or hold specified regulatory licenses. This flexibility enables network participants to configure validation environments that support various regulatory or operational needs.

L1s can also be configured as permissioned or private networks, in which only pre-approved validators may participate and the underlying blockchain data may be accessible only to those validators. Such configurations may be used by institutions or organizations that wish to maintain privacy over their on-chain data.

Because Avalanche supports a heterogeneous network of blockchains, not all validators are required to validate all blockchains. The L1 model allows validators to participate only in those blockchains or applications of interest, thereby reducing computational and operational overhead. In addition, individual L1s may impose technical requirements on validators — such as minimum hardware specifications — to ensure adequate performance for resource-intensive applications.

Validation and Staking

When AVAX is staked, it is deposited into a smart contract on Avalanche and remains locked up, meaning it cannot be transferred. Validation in the context of staking refers to the act of running a node on the blockchain network to validate transactions and secure the network. In proof-of-stake systems like Avalanche, validators create rewards as long as they stake the network’s token (“AVAX”) and correctly participate in the network. This mechanism helps secure the network by imposing the need to lock up value in the network in order to participate in the consensus decisions.

• Stake Requirement: To become a validator on the Avalanche Network, a user must stake a minimum amount of 2,000 AVAX tokens on the Mainnet (or 1 AVAX on the Fuji Testnet).

• Process: Validators participate in achieving consensus by repeatedly sampling other validators. The probability of being sampled is proportional to the validator’s stake, meaning the more tokens a validator stakes, the more influential they are in the consensus process.

• Rewards: Validators create rewards for their efforts in securing the network. To create rewards, a validator must be online and responsive for more than 90% (previously 80%) of their validation period.

Delegation allows token holders who do not wish to run their own validator node to still participate in staking by “delegating” their tokens to an existing validator node.

• Stake Requirement: To delegate on the Avalanche Network, a minimum of 25 AVAX tokens is required on the Mainnet (or 1 AVAX on the Fuji Testnet).

208

• Process: Delegators choose a specific validator node to delegate their tokens to, trusting that the validator will behave correctly and help secure the network on their behalf.

• Rewards: Delegators are also eligible to create rewards for their stake. The validator they delegate to shares a portion of the reward with them, according to the validator’s delegation fee rate.

In summary, validation involves actively participating in securing the network by running a node, while delegation allows token holders to participate passively by trusting their stake to a chosen validator. Both validators and delegators can create rewards, but validators have higher stakes and more direct involvement in the Avalanche Network.

Creation of New AVAX

At network genesis, approximately 360 million AVAX were minted and distributed. Additional AVAX is created as staking rewards under Avalanche’s proof-of-stake consensus mechanism. Validators who participate in securing the network by validating transactions and producing blocks may create newly minted AVAX at the conclusion of their staking period as a reward for honest and continuous participation.

In Avalanche, transaction fees paid in AVAX are permanently removed from circulation (“burned”). This includes fees incurred on the X-Chain, C-Chain, P-Chain and any other L1 networks that utilize AVAX as their gas token. Burned fees are not re-issued or recycled by the protocol.

Avalanche does not employ a “slashing” mechanism that deducts previously staked tokens for validator misbehavior. However, validators that are offline, misconfigured, or act maliciously may fail to create rewards for a given staking period, effectively losing potential yield.

As of May 5, 2026, the estimated reward rate for staking AVAX was 6.7%, meaning that, on average, stakers of AVAX are creating approximately 6.7% if they stake it for 365 days. As of May 5, 2026, the staking ratio, or the percentage of eligible AVAX tokens currently being staked, was approximately 42.17% of total supply.

Limits on AVAX Supply

The maximum supply of AVAX is fixed at 720 million tokens, which is enforced at the protocol level. The rate at which new AVAX is minted varies according to network parameters, including staking participation, reward rate and lock-up durations. As total supply approaches the 720 million-token limit, the rate of new issuance declines.

Because transaction fees are burned independently of issuance, total circulating supply may remain below the 720 million-token cap.

The Avalanche Network operates in a decentralized manner and does not rely on governmental authorities or financial intermediaries to issue, transfer or determine the value of AVAX. The value of AVAX is determined by market supply and demand, including trading on digital asset exchanges and peer-to-peer transactions.

Decentralized Finance (“DeFi”)

DeFi is a collective term for blockchain-based financial products and services accessible to anyone with an internet connection. It provides exposure to global markets and delivers banking-style capabilities that put users in direct control, with full transparency over their assets and transactions. The term DeFi covers a wide range of decentralized applications and protocols, including staking, lending, borrowing, token swapping and decentralized exchange (“DEX”) trading, margin trading, perpetual futures and options, liquidity provision (“LP”) in automated market makers (“AMMs”), decentralized auctions, prediction markets, yield farming, stablecoin issuance, real world assets (“RWA”), synthetic assets, cross-chain bridges and more. Avalanche is one of the dominant blockchains for DeFi, stemming from its pioneering role in programmable blockchain infrastructure, smart contracts and dApps.

209

Modifications to the Avalanche Protocol

Avalanche is an open-source, decentralized network that does not have a central governing authority. Accordingly, no single person or entity can unilaterally implement changes to the software that supports the network. A core group of independent developers maintains the open-source code for the Avalanche protocol and may propose modifications, enhancements, or periodic software updates. However, because Avalanche operates as a peer-to-peer network, each network participant — referred to as a node or validator — independently determines whether to adopt any proposed software release.

As a practical matter, modifications to the Avalanche Network are typically proposed as Avalanche Community Proposals (“ACPs”). Once an overwhelming majority of the Avalanche Network has signaled their support for an ACP, it may be scheduled for activation on the Avalanche Network by Avalanche Network clients. The Avalanche Foundation meets periodically to recommend the ratification of specific ACPs, but it is ultimately up to members of the Avalanche Network to adopt ACPs they support.

If a sufficient portion of validators elect not to upgrade their software, the applicable blockchain could become divided, resulting in a “fork” in which two separate and incompatible versions of the blockchain continue to operate. For additional information, see the risk factor titled “Pubco may be unable to recognize the economic benefit of a “fork” or an “airdrop”, which could adversely impact an investment in Pubco.”

Forms of Attack Against the Avalanche Network and Wallets

Blockchain technology incorporates security features intended to make it difficult for malicious actors to alter or corrupt the protocol or blockchain infrastructure. Nevertheless, as with any computer network, the Avalanche Network may be subject to various forms of attack. These include unauthorized access to digital wallets holding AVAX, and network-level attacks such as attempts to disrupt or manipulate the consensus process.

AVAX is controlled solely through possession of the private key associated with the digital wallet address in which the AVAX is held. Private keys are typically stored in hardware devices under the holder’s physical control, or through software applications that may be hosted locally or by a third-party custodian. Unauthorized access to a wallet can occur through phishing or other social-engineering attacks in which an attacker deceives a user into revealing private keys or recovery phrases. The loss or compromise of private keys may result in the permanent loss of access to, and effective loss of, the corresponding AVAX.

Because the Avalanche Network relies on a proof-of-stake consensus mechanism, a potential attack could occur if an entity or coordinated group of validators were to control a majority of the staked AVAX participating in consensus. Such a group could, in theory, attempt to delay or reorder transactions or otherwise compromise network integrity. The Avalanche protocol is designed to make such attacks economically unattractive, as acquiring and risking the amount of AVAX necessary to control consensus would likely exceed any potential short-term benefit and could undermine the value of the attacker’s own holdings.

The Avalanche Network may also be vulnerable to denial-of-service (“DoS”) attacks, in which an attacker seeks to disrupt normal network operation by overwhelming nodes with excessive traffic or transaction requests. A successful DoS attack could temporarily slow transaction processing or block creation. Although the Avalanche Network incorporates mechanisms to mitigate such risks, no blockchain network is entirely immune from them. The Avalanche Network has been, and can in the future be, subject to denial-of-service attacks, which can result in temporary delays in block creation and in the transfer of AVAX.

Avalanche Industry Participants

The primary participants in the Avalanche ecosystem include validators, investors and traders, digital asset exchanges, and service providers such as custodians, brokers, payment processors, wallet providers and financial institutions.

Validators range from individual Avalanche participants to professional node operators that maintain validator infrastructure to secure the network and validate transactions. Validators stake AVAX tokens as collateral to participate in consensus and, in return, create staking rewards. In addition to validators, token holders may delegate their AVAX to validators in exchange for a portion of the staking rewards. See “Creation of New AVAX” above.

210

AVAX investors and traders include both individuals and institutions who directly or indirectly purchase, hold and sell AVAX or AVAX-based financial instruments. Institutional engagement with Avalanche has increased as adoption of the network and its applications has expanded.

Digital asset exchanges provide venues for the purchase and sale of AVAX in exchange for fiat currencies or other digital assets. Exchange rates are determined by supply and demand dynamics across various trading platforms, which are not regulated in the same manner as traditional securities exchanges. In addition to spot trading, over-the-counter markets and derivatives referencing AVAX exist. The value of AVAX in the marketplace is influenced by factors such as network adoption, perceived utility as a store of value, transaction volume and market sentiment. See “Risk Factors — Risks Related to the Business and Strategy of Pubco.”

Service providers offer a range of support services to network participants, including custody, trade execution, payment processing and lending secured by AVAX collateral. If adoption of the Avalanche Network continues to expand, it is expected that the range and sophistication of these services will also increase.

Our AVAX Holdings

At the Closing, AVAT is expected to hold approximately 14,759,965 AVAX. The initial AVAX holdings will have been the result of a combination of contributions to be made pursuant to the Contribution Agreement, the TSA, the Company Unit Subscription Agreements and the Business Combination Agreement.

Custody of our AVAX

We currently hold, and after the Closing we will hold, all of our AVAX in custody accounts with Coinbase, Bitgo Trust Company, Inc. (“BitGo”) and Anchorage Digital Bank N.A. (“Anchorage”). As a result, the primary counterparty risk we will be exposed to with respect to our AVAX is performance obligations under the custody arrangements into which we have entered into with Coinbase, Bitgo and Anchorage. We aim to diversify our holdings between custodians, therefore our AVAX treasury management strategy does not include any fixed or preferred allocations between custodians, and is generally designed to preserve management’s flexibility and business judgment in deploying AVAX to different custodians and adapting to rapidly changing, fluid market conditions.

Our AVAX holdings from time to time may be concentrated with a single custodian. Our custodial services contracts do not restrict our ability to reallocate our AVAX among multiple custodians. In light of the significant amount of AVAX we hold, we may seek to engage further additional digital asset custodians to diversify the custody of our AVAX and our potential risk exposure to any one custodian. In addition to the other bespoke terms described below, each custodian agreement contains industry-standard fee terms.

In addition to custody arrangements with BitGo, Anchorage and Coinbase, we hold staking service agreements with staking service providers who provide validation services (as detailed below) concurrently while our AVAX remains custodied with BitGo, Anchorage and Coinbase. Our staking service providers charge fees typically in the range of approximately 2-3% of the USD value of earned staking rewards for each monthly period, meaning we typically retain 97-98% of the reward amount. Rewards are received at the end of each staking period, with current reward periods ranging from 15 days to 60 days. We currently do not have Company policies regarding lockup periods for staked AVAX or whether or not to automatically stake earned rewards, as we rely on the business judgment of our management on an ongoing basis. We believe this preservation of management’s flexibility and business judgment allows us to adapt to market conditions. As of May 4, 2026, approximately 99.99% of our AVAX was held in cold storage across our three current custody providers (each of which support cold-storage-based staking) and approximately 59.8% of our AVAX was staked.

Custody and Staking Agreements

BitGo Custodial Services Agreement

The Company has entered into a custodial services agreement with BitGo Trust Company, Inc. (the “BitGo Custodial Services Agreement”) to safeguard its digital assets. The BitGo Custodial Services Agreement has an initial term of one (1) year and automatically renews for successive one-year periods unless either party provides written notice of non-renewal at least sixty (60) days prior to the expiration of the then-current term. The agreement may be terminated by either party for cause, including material breach

211

not cured within thirty (30) days, or by BitGo in the event of legal, regulatory or risk concerns, or if the client fails to maintain required account balances or violates prohibited use policies. The Company may also initiate early termination by providing at least thirty (30) days prior written notice to Bitgo and by paying all outstanding amounts due under the custody agreement through termination as well as a one-time early termination fee. Under the BitGo Custodial Services Agreement, the Company’s digital assets are held in segregated custody accounts, separate from BitGo’s proprietary assets and from the assets of other clients, and are not reflected on BitGo’s balance sheet. Only designated and authorized personnel of the Company may initiate transactions, subject to security protocols and multi-factor authentication, with BitGo acting solely on verified instructions. BitGo maintains commercially reasonable insurance coverage for assets held in custody, which is shared among all BitGo clients and is intended to cover certain losses, subject to policy terms and conditions. Because such insurance coverage is shared among all BitGo clients and is not specific to us, it may be insufficient to protect against all losses of our AVAX held with BitGo. BitGo is not permitted to lend, pledge or otherwise encumber the Company’s assets, and the Company retains full ownership of all assets held in custody. BitGo is required to maintain accurate books and records of all transactions and to provide periodic account statements. In the event of termination, the Company must withdraw all assets within ninety (90) days, subject to applicable law. BitGo also provides staking services.

Coinbase Prime Broker Agreement

The Company has entered into a Prime Broker Agreement with Coinbase on behalf of Coinbase Custody Trust Company, LLC (the “Coinbase Prime Broker Agreement”) for the secure storage of its digital assets. The Coinbase Prime Broker Agreement is effective until terminated by either party, with either party able to terminate for any reason upon thirty (30) days’ prior written notice, or immediately for cause by Coinbase for an event of default including breach of agreement, insolvency, regulatory or legal concerns, or other specified events of default. Pursuant to the Coinbase Prime Broker Agreement, the Company’s digital assets are held in one or more segregated custody wallets in the Company’s name, separate from Coinbase’s proprietary assets and from the assets of other clients, and are not available to satisfy claims of Coinbase’s creditors. Only authorized representatives of the Company may provide instructions to Coinbase for the movement of assets, and all such instructions are subject to Coinbase’s security protocols, including multi-factor authentication and verification procedures. Coinbase is not permitted to lend, pledge, hypothecate, or otherwise encumber the Company’s assets without the Company’s written consent. Coinbase maintains insurance coverage intended to protect against certain losses, including theft or security breaches, subject to the terms and limits of the policy, which is shared among all Coinbase clients. Because such insurance coverage is shared among all Coinbase clients and is not specific to us, it may be insufficient to protect against all losses of our AVAX held with Coinbase. In addition, Coinbase provides monthly electronic account statements detailing balances and activity. Upon termination of the agreement, the Company is required to withdraw its assets within thirty (30) days, subject to applicable law and any outstanding obligations.

Under the Coinbase Prime Broker Agreement, the Company may choose to engage Coinbase to provide validator services pursuant to a separate agreement, or may choose to contract with other third-party staking facilitation services. Currently, the Company uses third-party staking services for all of the AVAX holdings custodied with Coinbase and does not engage with Coinbase under any separate agreement for the provision of validator services. The Coinbase Prime Broker Agreement is subject to modification by Coinbase with prior notice.

Anchorage Master Custody Service Agreement

The Company has entered into a Master Custody Service Agreement with Anchorage (the “Anchorage Master Custody Service Agreement”). The agreement has an initial term of one (1) year and will be automatically renewed for successive one (1) year periods unless either party sends written notice of termination no less than thirty (30) days prior to the expiration of the current term. The agreement may be terminated by the non-breaching party for a material breach not cured within thirty (30) days upon receipt of written notice, or by either party in the case that any part of the services agreed to are determined to be in violation of applicable laws or raise material regulatory, risk or reputational issues, among other specified conditions. Under the Anchorage Master Custody Service Agreement, the Company’s digital assets are held in segregated custody accounts, separate from Anchorage’s proprietary assets and from the assets of other clients. Only authorized personnel of the Company may initiate transactions, subject to Anchorage’s security protocols. Anchorage is not permitted to use, lend, or otherwise encumber the Company’s assets for its own benefit, and the Company retains full ownership of all assets held in custody. Anchorage, through its parent company, maintains a commercial crime insurance policy, which is intended to cover the loss of client assets held in cold storage, including from employee collusion or fraud, physical loss including theft, damage of key material, security breach or hack, and fraudulent transfer, subject to its terms and conditions. The insurance maintained by Anchorage is shared among all of its customers, is not specific to AVAT, and may not be available or sufficient to protect AVAT from any or all possible losses or sources of losses. Anchorage is required to maintain

212

accurate records of all transactions and to provide monthly account statements. In the event of termination, the Company is required to withdraw all assets, subject to applicable law and the terms of the agreement.

Chorus One AG (“Chorus One”) Master Services Agreement

Under the master services agreement between Chorus One and the Company, Chorus One provides blockchain node infrastructure and validator hosting services for the Company’s AVAX. The master services agreement includes quarterly invoicing and a 99.5% infrastructure uptime commitment. Either party may terminate with 30 days’ notice.

Republic Crypto LLC (“Republic Crypto”) Infrastructure Services Agreement

Under the infrastructure services agreement between Republic Crypto and the Company, Republic Crypto hosts and maintains Avalanche validator nodes on behalf of the Company. The Company must maintain a minimum stake of 500,000 AVAX per validator. The infrastructure services agreement may be terminated for convenience by the Company with 30 days’ notice.

Tarmac Labs Inc. (“Tarmac Labs”)

Tarmac Labs provides non-custodial staking node services to the Company pursuant to terms of service which the Company is deemed to have agreed to by virtue of using the service. The terms include up to 25 validators, with a minimum stake of 250,000 AVAX. The terms of service also include a 99% monthly uptime service level agreement, and allows for termination by either party with 120 days’ notice or for breach.

Direct Staking Services Agreement with ParaFi Technologies LLC (“ParaFi”)

Through a direct staking services agreement between ParaFi and the Company, ParaFi operates private validator nodes to which the Company stakes certain tokens, with the Company retaining custody of rewards. The direct staking services agreement with ParaFi is non-custodial, with either party able to terminate on 15 days’ notice.

We have and will continue to carefully select our AVAX custodians after undertaking a due diligence process. As part of our custodian selection process, we have and will continue to evaluate and select custodians that can demonstrate that they operate with strict security protocols, including multifactor authentication procedures designed to safekeep our AVAX. In addition, our custodial services agreements specify that the private keys that control our AVAX will be held in “cold” storage, which is designed to mitigate risks that a system may be susceptible to when connected to the internet, including the risks associated with unauthorized network access and cyberattacks. We also negotiate liability provisions in our custodial contracts, pursuant to which our custodians are generally held liable for their failure to safekeep our AVAX, except in certain circumstances.

We also plan to conduct due diligence reviews during the custodial relationship to monitor the safekeeping of our AVAX. We expect to conduct supplemental due diligence in the future when we believe it is warranted by market circumstances or otherwise.

For a discussion of risks relating to the custody of our AVAX, see “Risk Factors — Risks Related to the Business and Strategy of Pubco.”

Airdrops, Forks, and Incidental Rights

As a holder of AVAX, AVAT may from time to time become entitled to receive additional rights or assets arising from forks, airdrops or other incidental entitlements related to the Avalanche Network. We intend to determine whether and how to recognize such assets in coordination with our partner custodians at the time. We may not immediately, or ever, have the ability to access or withdraw digital assets received through forks or airdrops, particularly when AVAX is held with third-party custodians.

Future forks of the Avalanche protocol, while rare, may occur at any time and can result in operational disruptions, cybersecurity incidents, replay attacks or other network vulnerabilities, any of which could cause temporary or permanent loss of our or our counterparties’ assets. As significant forks of the Avalanche protocol are rare, AVAT does not have specific policies and procedures related to forks of the Avalanche protocol.

213

Any material value realized from incidental rights will be recognized and disclosed in accordance with applicable accounting standards and regulatory requirements.

Potential Advantages and Disadvantages of Holding AVAX

We believe that AVAX represents an attractive digital asset due to its potential role as a store of value supported by a robust, open-source and decentralized architecture that is not controlled by any central authority. Because the total supply of AVAX is capped, it is designed to be a scarce asset that could serve as a potential hedge against monetary debasement.

AVAX exists entirely in digital form as transaction records on the Avalanche blockchain. Transactions are verified not by a central authority but by a decentralized network of validators participating in a proof-of-stake consensus mechanism. This decentralization helps mitigate certain risks common to centralized systems, such as single points of failure, and reduces the dependency of the Avalanche Network on any one participant.

However, while the Avalanche Network as a whole is decentralized, the private keys required to access AVAX balances are controlled by individual holders or custodians and may be vulnerable to theft, loss or compromise through phishing or other cybersecurity attacks. Loss of private keys can result in the permanent loss of the associated AVAX.

In addition, holdings of AVAX are subject to risks inherent in any form of electronic data storage, including power failure, data corruption, security breaches and human error. As a result, AVAX may be more susceptible to theft, destruction or loss of value from technological vulnerabilities compared to conventional fiat currency or traditional financial assets. See “Risk Factors — Risks Related to the Business and Strategy of Pubco.”

The Avalanche Network depends on open-source developers and validator communities to maintain and improve its protocol. Accordingly, the network may be subject to future protocol changes, governance disputes, forks or the emergence of competing protocols, any of which could adversely affect the operation or value of AVAX.

AVAX Markets and Exchanges

AVAX is widely traded on both centralized and decentralized cryptocurrency exchanges. Major centralized exchanges that list AVAX include Binance, Coinbase, Kraken, KuCoin, and Bitfinex. These platforms allow users to buy, sell and trade AVAX against various fiat currencies (such as USD, EUR) and other cryptocurrencies like Bitcoin or Ether.

AVAX is also available on decentralized exchanges like Trader Joe, Pangolin and SushiSwap, which operate directly on the Avalanche Network or support cross-chain trading. Decentralized exchanges allow users to trade AVAX in a peer-to-peer manner without the need for an intermediary, using smart contracts to facilitate transactions.

AVAX Futures Markets

Futures contracts are derivative products that allow traders to speculate on the future price of AVAX without owning the underlying asset. AVAX futures are available on several major cryptocurrency derivatives exchanges, including Binance, Bybit and Bitget. These platforms offer perpetual contracts and fixed-term futures, often with leverage, enabling traders to amplify their exposure to AVAX price movements.

Competition

Our AVAX strategy generally involves from time to time, subject to market conditions, issuing debt or equity securities which may be subscribed for in AVAX or cash or engaging in other capital raising transactions with the objective of using the proceeds to purchase AVAX. When we engage in such transactions, we compete with, among others, other companies that hold AVAX or other digital assets as treasury reserve assets, ETPs, digital assets exchanges, other digital assets service providers, private funds that invest in AVAX and other digital assets and similar vehicles. An increase in the competition for sources of AVAX and sources of capital could adversely affect the availability of AVAX and the cost of financing for our AVAX purchases, and thereby could adversely affect the market price of shares of Pubco Class A Stock.

214

The market for Avalanche financial and technology infrastructure is highly competitive and rapidly evolving and expanding across several segments, such as validating hardware, custody, wallets, trading platforms and analytics. Existing players include leading technology platforms and Avalanche analytics and data providers. These segments continue to grow rapidly to cater to increasing institutional needs. The market for related products and services face constant new entrants and price pressure, with players differentiating themselves through innovation, efficiency, regulatory alignment and value-add services.

The market for Avalanche financial and technology infrastructure is subject to material uncertainties, including volatility in public interest, changes in regulatory treatment of cryptocurrencies and reputational risks associated with the broader cryptocurrency sector. These and other factors may materially impact the business, financial condition and results of operations of companies operating in this sector.

Government Regulation

The laws and regulations applicable to AVAX and digital assets are evolving and subject to interpretation and change.

Governments around the world have reacted differently to digital assets. Certain governments have deemed them illegal, and others have allowed their use and trade without restriction, while in some jurisdictions, such as the U.S., digital assets are subject to overlapping, uncertain and evolving regulatory requirements.

As digital assets have grown in both popularity and market size, the U.S. Executive Branch, Congress and a number of U.S. federal and state agencies, including the Financial Crimes Enforcement Network, the CFTC, the SEC, the Financial Industry Regulatory Authority, the Consumer Financial Protection Bureau, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial regulators, have been examining the operations of digital asset networks, digital asset users and digital asset exchanges, with particular focus on the extent to which digital assets can be used to violate state or federal laws, including to facilitate the laundering of proceeds of illegal activities or the funding of criminal or terrorist enterprises and the safety and soundness and consumer-protective safeguards of exchanges or other service-providers that hold, transfer, trade or exchange digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies and other countries have issued rules or guidance regarding the treatment of digital asset transactions and requirements for businesses engaged in activities related to digital assets.

Depending on the regulatory characterization of AVAX, the markets for AVAX in general, and our activities in particular, our business and our AVAX strategy may be subject to regulation by one or more regulators in the United States and globally. Ongoing and future regulatory actions may alter, to a materially adverse extent, the nature of digital assets markets, the participation of industry participants, including service providers and financial institutions in these markets, and our ability to pursue our AVAX strategy. Additionally, U.S. state and federal and foreign regulators and legislatures have taken action against industry participants, including digital assets businesses, and enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from digital assets activity. U.S. federal and state energy regulatory authorities are also monitoring the total electricity consumption of cryptocurrency mining, and the potential impacts of cryptocurrency mining to the supply and dispatch functionality of the wholesale grid and retail distribution systems. Many state legislative bodies have passed, or are actively considering, legislation to address the impact of cryptocurrency mining in their respective states.

The CFTC takes the position that many digital assets fall within the definition of a “commodity” under the Commodities Exchange Act of 1936, as amended (the “CEA”), and we believe that the CFTC would classify AVAX as a commodity. Under the CEA, the CFTC has broad enforcement authority to police market manipulation and fraud in spot digital assets markets in which we may transact. Beyond instances of fraud or manipulation, the CFTC generally does not oversee cash or spot market exchanges or transactions involving digital asset commodities that do not utilize margin, leverage or financing. In addition, CFTC regulations and CFTC oversight and enforcement authority apply with respect to futures, swaps, other derivative products and certain retail leveraged commodity transactions involving digital asset commodities, including the markets on which these products trade.

As a commodity, AVAX trades on spot digital asset markets, which are subject to the CFTC’s enforcement authority to police market manipulation and fraud. Beyond instances of fraud or manipulation, the CFTC generally does not oversee cash or spot market exchanges or transactions involving digital asset commodities that do not utilize margin, leverage or financing (i.e., retail commodity transactions). On September 2, 2025, the SEC and CFTC issued a joint statement clarifying that SEC- and CFTC-registered exchanges are permitted to facilitate the trading of certain spot commodity products. Futures, swaps and retail commodity transactions involving

215

commodities are regulated by the CFTC. AVAX futures and retail commodity transactions involving AVAX involving U.S. persons must occur on a CFTC-registered exchange.

Congress has taken steps towards enacting legislation regarding digital assets market structure. For instance, on July 17, 2025, the U.S. House of Representatives passed the CLARITY Act, which, if enacted, would allocate jurisdiction between the SEC and CFTC with respect to digital assets and subject spot trading of digital assets that are commodities to regulation by the CFTC. Additionally, the U.S. Senate is considering legislation that would provide a comprehensive regulatory framework for digital assets aimed at clarifying jurisdiction between the SEC and CFTC. The U.S. Senate Committee on Agriculture, Nutrition, and Forestry has advanced the Digital Commodity Intermediaries Act, which like the CLARITY Act, would subject spot trading of digital assets that are commodities to CFTC regulation.

The SEC and its staff have taken the position that certain other digital assets fall within the definition of a “security” under the U.S. federal securities laws. Public statements made by senior officials and senior members of the staff at the SEC indicate that the SEC does not consider AVAX to be a security under the federal securities laws. However, such statements are not official policy statements by the SEC and reflect only the speakers’ views, which are not binding on the SEC or any other agency or court and cannot be generalized to any other digital assets.

In addition, since transactions in AVAX provide a degree of anonymity, they are susceptible to misuse for criminal activities, such as money laundering. This misuse, or the perception of such misuse, could lead to greater regulatory oversight of AVAX and the Avalanche platform, and there is a possibility that law enforcement agencies could close or blacklist AVAX platforms or other Avalanche-related infrastructure with little or no notice and prevent users from accessing or retrieving AVAX held via such platforms or infrastructure. For example, the U.S. Treasury Department’s Office of Foreign Assets Control has issued updated advisories regarding the use of virtual currencies, added a number of digital asset exchanges and service providers to the Specially Designated Nationals and Blocked Persons list and engaged in several enforcement actions, including a series of enforcement actions that have either shut down or significantly curtailed the operations of several smaller digital asset exchanges associated with Russian and/or North Korean nationals. Additionally, in January 2025, the Consumer Financial Protection Bureau announced that it is seeking public input on privacy protections and surveillance in digital payments, particularly those offered through large technology platforms.

In addition, there has been increasing focus on the extent to which digital assets can be used to launder the proceeds of illegal activities, fund criminal or terrorist activities or circumvent sanctions regimes, including those sanctions imposed in response to the ongoing conflict between Russia and Ukraine. In order to address these risks, as of Closing, we will have implemented and will maintain policies and procedures reasonably designed to promote compliance with applicable AML, KYC and sanctions laws and regulations. Our compliance framework is designed to primarily rely on transacting with regulated third-party entities, such as registered money services businesses or financial institutions, that are themselves subject to robust AML, KYC and related compliance rules in the United States, thereby mitigating these risks. For additional information, see the risk factor titled “Although Pubco will have relevant due diligence procedures at Closing regarding anti-money laundering (“AML”) and know-your-customer (“KYC”), these procedures may fail to prevent illegal transactions, which could subject Pubco to criminal and civil liabilities and impact the value of the shares of Pubco Class A Stock.”

As noted above, activities involving AVAX and other digital assets may fall within the jurisdiction of more than one financial regulator and various courts and such laws and regulations are rapidly evolving and increasing in scope. On January 23, 2025, President Trump issued an executive order titled, Strengthening American Leadership in Digital Financial Technology. While the executive order did not mandate the adoption of any specific regulations, the executive order identifies certain key objectives to guide agencies involved in crypto regulation, including (i) protecting the sovereignty of the United States dollar by promoting the development of United States dollar-backed stablecoins, (ii) providing regulatory clarity and certainty built on technology-neutral regulations for individuals and firms involved in digital assets, including through well-defined jurisdictional regulatory boundaries, and (iii) taking measures to protect Americans from the risks of Central Bank Digital Currencies. To achieve these objectives, the executive order established a working group on digital asset markets within the National Economic Council, comprised of representatives from key federal agencies, with a tight timeline for examining existing regulations and proposing a new regulatory framework. There have also been several bills introduced in Congress, including the CLARITY Act, RFIA, DCIA and the GENIUS Act that propose to establish additional regulation and oversight of the digital asset markets. For additional information, see the risk factor titled “AVAX and other digital assets are novel assets, which will expose Pubco to significant legal, commercial, regulatory and technical uncertainty, which could materially adversely affect Pubco’s financial position, operations and prospects.”

216

AVAT is in the process of implementing, and intends to implement prior to Closing, an Anti-Money Laundering and Sanctions Policy that will be designed to facilitate compliance with the Bank Secrecy Act and applicable U.S. sanctions laws and regulations via controls, screening tools and other appropriate measures that are customary in AVAT’s industry.

Intellectual Property

As of the date of this filing, AVAT maintains and uses trade names, unregistered trademarks, domain names and logos, which it considers material to its brand identity. AVAT may pursue registration of certain marks or content in additional jurisdictions as appropriate.

As of the date of this filing, other than as described above, AVAT does not otherwise own any intellectual property.

Human Capital

As of the Closing, we will have a total of five employees, of whom all will be based in the United States. None of our employees will be covered by a collective bargaining agreement. We may engage third-party contractors and consultants on an as-needed basis.

We are a remote-first company. We believe that allowing personnel to work in the location that best meets their needs and preferences presents an attractive opportunity for a larger pool of high-quality candidates and a competitive advantage in hiring and retaining talent in the United States and worldwide.

Personnel management is essential to the growth of our business. Our aim is to create a dynamic lean team of personnel where employees are motivated by our mission and routinely engaged in activities that are meaningful to their career progression and have opportunities for professional development.

Legal Proceedings

From time to time, AVAT or any of their respective subsidiaries may become involved in legal proceedings or be subject to claims arising in the ordinary course of their business. None of AVAT or any of their respective subsidiaries is currently a party to any legal proceedings, the outcome of which, if determined adversely, is reasonably expected to individually or in the aggregate have a material adverse effect on their business or financial condition.

THE COMPANY’S MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

References in this section to “AVAT,” “we,” “us,” or “our” are to the Company and its consolidated subsidiaries, in each case prior to the Business Combination, and Pubco and its consolidated subsidiaries after giving effect to the Business Combination. The following discussion and analysis provides information which AVAT’s management believes is relevant to an assessment and understanding of its results of operations and financial condition. This discussion and analysis should be read together with the sections of the proxy statement/prospectus entitled “Information Related to AVAT” and AVAT’s audited financial statements and related notes thereto that are included elsewhere in the proxy statement/prospectus. In addition to historical financial information, this discussion and analysis contains forward-looking statements based upon current expectations that involve risks, uncertainties and assumptions. See the section entitled “Cautionary Note Regarding Forward-Looking Statements.” Actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” or elsewhere in the proxy statement/prospectus.

Overview

AVAT is a newly formed operating company focused exclusively on business lines relating to Avalanche and AVAX.

Our strategy is to offer public-market investors a differentiated, capital-efficient way to gain exposure to Avalanche and AVAX through (i) the targeted accumulation of AVAX; (ii) tailored treasury management geared towards staking yield and other asset management levers intended to compound AVAX per share over time and (iii) the further ecosystem integration including the potential provision of Avalanche-focused infrastructure, such as the operation of validator nodes, L1 activation and other corporate development activities, that we believe will expand our exposure to Avalanche.

AVAT was formed in Delaware as a limited liability company on August 20, 2025.

AVAT has no operating history and has not yet generated any revenue. However, at Closing, Pubco will be an operating company engaged in a number of business strategies focused on AVAX. Following the Closing, AVAT will execute its strategy through three principal pillars that define our differentiated operating model and are designed to support long-term AVAX accumulation, disciplined treasury growth and development of AVAX-related infrastructure. Each such pillar is further described below.

AVAT’s ability to generate revenue sufficient to achieve profitability will depend on, among other factors, its ability to raise capital to acquire additional AVAX, secure participation and contribution from AVAX holders through in-kind investments, successfully apply yield generation strategies, financial trading strategies and risk-management techniques in its active management of its AVAX holdings and develop or enter into partnerships for end-to-end AVAX-focused financial and technology infrastructure.

Business Combination with MLAC

On October 1, 2025, MLAC, Pubco, MLAC Merger Sub, Company Merger Sub, AVAT and the Seller entered into the Business Combination Agreement. Pursuant to the Business Combination Agreement, and subject to the terms and conditions set forth therein, (a) on the Closing Date but prior to the Closing, MLAC will effect the Domestication, pursuant to which MLAC will transfer by way of continuation to and become a Delaware corporation, (b) at least two hours after the Domestication, the MLAC Merger will be consummated, and with MLAC Shareholders receiving one share of Pubco Class A Stock for each MLAC Class A Ordinary Share held by such shareholder, and with each holder of MLAC Rights receiving one share of Pubco Class A Stock in exchange for every ten (10) MLAC Rights held by such holder, and (c) Company Merger Sub will merge with and into the Company, with the Company continuing as the surviving company, with (i) each Company Member other than the Seller receiving one share of Pubco Class A Stock for each Company Unit held immediately prior to the effective time of the Company Merger and (ii) the Seller receiving one share of Pubco Class A Stock and one share of Pubco Class B Stock for each Company Unit it holds, in each case, as described in the section entitled “The Business Combination Proposal — The Business Combination Agreement.”

Concurrently with the signing of the Business Combination Agreement, on October 1, 2025, Pubco, Company and MLAC entered into the Company Unit Subscription Agreements with the Company Unit Investors, pursuant to which the Company Unit Investors purchased, payable in cash, USDC or AVAX, and the Company issued and sold, approximately $216 million worth of Company Units

218

at a price of $10.00 per Company Unit, in the Company Unit Subscription. At the Company Merger Effective Time, each Company Unit held by Company Unit Investors will be converted automatically into one share of Pubco Class A Stock.

Concurrently with the execution of the Business Combination Agreement and the TSA, the Seller, Company, Pubco, Avalanche BVI and Avalanche Cayman entered into the Contribution Agreement, pursuant to which, (a) the Foundation sold a minimum of $200 million of AVAX tokens on a pre-discount basis to Company and (b) the Seller contributed, directly and indirectly through certain related funds, 1,960,040 AVAX tokens to the Company in exchange for 5,805,638 Company Units.

Concurrently with the execution of the Business Combination Agreement and the Contribution Agreement, the Company, Pubco, Avalanche BVI and Avalanche Cayman entered into the TSA, pursuant to which, in October 2025, the Foundation sold a minimum of $200 million of AVAX tokens on a pre-discount basis to the Company in exchange for, at a 60% discount, (i) $50 million in cash or USDC and (ii) $30 million in the form of up to 3,000,000 shares of Pubco Class A Stock and a certain number of pre-funded warrants convertible into Pubco Class A Stock in the event the Foundation’s beneficial ownership of the Company is expected to exceed the Maximum Percentage at Closing.

Principal Factors Affecting Our Results of Operations and Material Trends

AVAT’s future results are expected to be impacted by the highly volatile nature of AVAX’s valuation, as well as conditions and trends relating to demand for AVAX or other digital assets. We also expect AVAT’s future results to be impacted by the successful execution of our business strategies, such as our AVAX acquisition strategy, our support of L1s and validator resources, our fostering of partnerships with respect to our AVAX financial and technological infrastructure solutions, regulatory and technical developments surrounding AVAX and cryptocurrencies, the rapid evolution of the AVAX technology infrastructure landscape and our ability to innovate in and add value to the AVAX ecosystem. The primary factors that are expected to impact our results and present significant opportunities, as well as pose risks and challenges, are described below. We believe that our performance and future success depends on the factors discussed below, as well as those mentioned in the section titled “Risk Factors” and elsewhere in this proxy statement/prospectus.

The following macroeconomic factors and trends as they relate to AVAX may specifically impact our business:

• Price of AVAX. Our business is expected to be heavily dependent on the price of AVAX, which has historically experienced significant volatility. We have acquired AVAX, and may in the future acquire additional AVAX, through at-market purchases to build our strategic reserve of AVAX. Under ASU 2023-08, Intangibles-Goodwill and Other-Crypto Assets (Subtopic 350-60): Accounting for and Disclosure of Crypto Assets (“ASU 2023-08”), AVAX is revalued at fair value at the end of each reporting period, with changes in fair value recognized in net income. As a result, fluctuations in the price of AVAX may significantly impact our results of operations.

• Awareness. We expect the perception of Avalanche as a legitimate and secure blockchain network, and in turn the perception of AVAX as a legitimate and secure asset class, by the general public will plays a crucial role in the success of our business. The pace and effectiveness of continued education and awareness is expected to impact adoption rates. Due to the rapidly evolving nature of digital assets and the volatile price of AVAX, which has experienced and continues to experience significant movements, we expect that our operating results will fluctuate significantly from quarter to quarter in accordance with market sentiments and movements in the broader AVAX economy.

• Regulation. The global regulatory and political landscape for AVAX, including developments concerning legal status, accounting and tax treatment and other compliance-related programs surrounding digital assets will significantly impact the popularity and value of AVAX. Political support or favorable regulations may encourage adoption, while restrictive measures may hinder it, which, in each case, may have a significant impact on our business.

• Institutional Adoption. Increased participation by institutional investors, including hedge funds, mutual funds, corporations and nation states can drive market confidence and liquidity, supporting continued growth and utility of AVAX and the Avalanche blockchain network.

219

• Monetary Policy. Central bank monetary policies, especially those related to interest rates and monetary supply, may influence AVAX adoption. Low-interest rates and expansive monetary policies that lead to currency debasement may lead to a search for alternative investments like AVAX, which may have a positive impact on our business.

• Technological Innovation. Advances in blockchain technology, improvements in scalability and enhanced security protocols may increase AVAX adoption and integration of AVAX and the Avalanche blockchain network into various financial systems. Conversely, as blockchain technology and digital asset become more widely accept, we expect competition to further intensify in the future. We will compete for capital, and the Avalanche blockchain network will compete for user adoption, with a number of companies and ecosystem participants within the United States and abroad, including those that focus on traditional financial services and those that focus on blockchain or AVAX-focused services and technology infrastructure.

Plan of Operations and Expected Revenue Sources

AVAT anticipates revenue generation through the following key business lines in the initial period following the Business Combination:

• AVAX Accumulation at Scale. As a publicly listed operating company at Closing, AVAT aims to broaden access to AVAX for a wide range of public-market investors with diverse objectives and risk profiles by opportunistically offering a range of capital raising instruments that present varying degrees of Avalanche and AVAX exposure. AVAT intends to accumulate AVAX over time through a blended offering of equity and debt instruments, which may be subscribed with cash or AVAX, as well as the deployment of non-AVAX offering proceeds to acquire additional AVAX in the market. Such offerings and acquisitions will be strategically considered and paced based on market conditions and other factors, including (i) market price of AVAX and related trends, (ii) macroeconomic factors, (iii) market appetite and demand and (vi) the Pubco Class A Stock price, including such price relative to the net asset value of its AVAX holdings. AVAT does not currently intend to hold any other cryptocurrencies as its main treasury asset, however it may, in the execution of its strategy, periodically hold other digital assets. AVAT retains the flexibility to sell AVAX under certain circumstances, such as to meet operational needs, comply with legal or regulatory obligations, pursue certain investment strategies or for general corporate purposes. In addition, where the Pubco Class A Stock trades at a meaningful discount to our estimated mNAV relative to the prevailing AVAX price, we may sell a portion of our AVAX to fund opportunistic share repurchases. We believe this disciplined capital-allocation approach — dynamically arbitraging the relationship between our share price, implied premium/discount to mNAV and the AVAX price — can be accretive to mNAV per share and align with long-term shareholder value. Any such activity would be subject to applicable law, our liquidity and risk parameters, market conditions, internal Board and relevant committee authorization, and there can be no assurance that any repurchases will be undertaken. AVAT does not currently plan to engage in hedging its AVAX exposure. AVAT retains the option to revisit its AVAX accumulation strategy or any related policies periodically as part of its ongoing strategic review and risk management.

• Active AVAX Treasury Management. AVAT’s active AVAX treasury management strategy will initially target (i) the staking of AVAX and (ii) the deployment of AVAX to traders, market makers, asset managers and other crypto market participants to with the goal of adopting conservative yield approaches focused on preservation and consistent returns, in each case subject to market conditions and other factors, intended to generate AVAX for treasury growth or the payment of operating expenses. To optimize staking returns while mitigating risks, we intend to carefully monitor our staking operations. This begins with the selection and oversight of trusted third-party staking providers, and extends to ongoing operational involvement. For example, we intend to conduct independent monitoring of validator performance alongside periodic reports provided by our staking service providers and to reinvest accrued staking rewards into the establishment of additional validators, where practicable. These practices are intended to support compounding yield, safeguard validator performance and promote transparency throughout our AVAX staking process. Determinations with respect to our AVAX management strategy, particularly with regards to the deployment of AVAX, other digital assets or fiat to traders, market makers, asset managers and other crypto market participants to execute any of our trading or yield strategies, will be made from time to time by assessing market factors including, but not limited to, (i) the current market price of AVAX, (ii) price trends and market level analysis, (iii) analysis of the broader macroeconomic environment and (iv) AVAT’s relative stock performance. In pursuit of this strategy, we may utilize AVAX-specific key performance indicators including AVAX reserves per share to assess our performance and guide our operations. These KPIs are intended to efficiently communicate AVAT’s mission of providing the best vehicle for secure, transparent and yield-generating exposure to AVAX at institutional scale.

220

Management’s AVAX strategy does not include any fixed delegation or staking percentages or allocations, and is generally designed to preserve management’s flexibility and business judgment in deploying AVAX and adapting to rapidly changing, fluid market conditions. For example, longer staking durations can amount to less liquidity – in periods where greater liquidity is desired, management may elect to pursue exclusively shorter staking durations. This strategy also contemplates that AVAT may, from time to time, subject to market conditions and other factors, (i) sell AVAX for general corporate purposes or in furtherance of strategies that AVAT believes are accretive to shareholders, (ii) enter into additional capital raising transactions and (iii) consider the pursuit of strategies that monetize or otherwise utilize its AVAX holdings to generate funds or income streams through the development and commercialization of new AVAX-based smart contracts and decentralized applications (“dApps”) for services and products. AVAT does not currently delegate, but may in the future.

• AVAX Technology and Ecosystem Partner. In addition to aiming to deliver secure, transparent and yield-generating exposure to AVAX at an institutional scale, AVAT may pursue a range of additional Avalanche-related business activities. After the Closing, we intend to evaluate opportunities to operate our own validator nodes independent of third-party service providers to consolidate our staking efforts. We also plan to actively support and engage with Avalanche-native projects via potential ecosystem partnerships with enterprises, asset managers and other participants, and also via early participation in emergent protocols and L1s. We expect to provide turnkey infrastructure solutions for enterprises, decentralized autonomous organizations and Avalanche-native builders seeking access to Avalanche’s consensus and blockspace economy. We may also pursue on-chain opportunities that offer attractive risk adjusted returns, such as infrastructure solutions for Avalanche-native builders or other staking solutions for enterprises and funds seeking to generate AVAX-denominated revenue. The development and launch of any such activities would require significant organizational, operational and regulatory preparation. These initiatives are subject to various legal and compliance considerations, including oversight by the SEC, the CFTC, FinCEN and state-level regulators such as those in Delaware, as well as compliance with applicable anti-money laundering and other financial laws. Planning for these potential activities is expected to begin following the consummation of the Business Combination; however, there can be no assurance as to the timing or outcome of any such efforts.

Results of Operations

From August 20, 2025 (inception) through December 31, 2025, AVAT generated $1,434,669 of staking revenue, net of fees. Our ability to generate revenue sufficient to achieve profitability will depend on, among other factors, our ability to raise capital to acquire additional AVAX, secure participation and contribution from AVAX holders through in-kind investments, successfully apply yield generation strategies, financial trading strategies and risk-management techniques in its active management of its AVAX holdings and develop or enter into partnerships for end-to-end AVAX-focused financial and technology infrastructure.

For the period from inception to December 31, 2025, AVAT had a net loss of approximately $59.6 million, which consisted primarily of general and administrative expenses of $1.2 million, impairment of digital assets of $13.6 million, a realized loss on digital assets of $2.1 million, and a change in fair value of digital assets of $96.3 million, offset by change in fair value of token sale liability of $52.2 million.

Risks and Uncertainties Associated with Future Results of Operations

We do not have an operating history, which makes it difficult to accurately forecast our future results of operations, and which is subject to a number of uncertainties, including our ability to grow the value of our AVAX holdings, develop and implement our AVAX-focused infrastructure strategy and the market size and growth opportunities in each of our anticipated lines of business.

Our ability to generate cash flow initially will largely be dependent on our ability to raise capital to acquire additional AVAX, secure participation and contribution from AVAX holders through in-kind investments, successfully apply yield generation strategies, financial trading strategies and risk-management techniques in our active management of our AVAX holdings and develop or enter into partnerships for end-to-end AVAX-focused financial and technology infrastructure. Our business strategy may not be realized as quickly as planned, or even at all. Further, even if we achieve growth in the near term, in future periods that growth could slow or decline for a number of reasons, including, but not limited to, AVAX volatility, increased competition, digital assets that compete with and may result in a decline in utilization of AVAX or replace AVAX, our inability to develop, improve or effectively scale AVAX acquisition or to develop or enter into partnerships for AVAX-related infrastructure, government regulation or our failure, for any reason, to continue to take advantage of any growth opportunities. For additional information see the section entitled “Risk Factors — Risks Related to the Business and Strategy of Pubco.”

221

Liquidity and Capital Resources

AVAT reported a net loss of $59,595,550 for the period from August 20, 2025 (inception) to December 31, 2025. As of December 31, 2025, AVAT had an aggregate cash balance of $1,758,802 and a net working capital deficit of $31,941,731.

AVAT assesses its liquidity in terms of its ability to generate adequate amounts of cash to meet current and future needs. Its expected primary uses of cash on a short and long-term basis are for working capital requirements, business acquisitions and other liquidity needs. AVAT’s management expects that future operating losses and negative operating cash flows may increase from historical levels because of additional costs and expenses related to the business operations and the development of market and strategic relationships with other businesses.

AVAT’s future capital requirements will depend on many factors, including the timing of the consummation of the Business Combination. In order to finance our growth, we will need to raise additional financing. If additional financing is required from outside sources, we may not be able to raise such capital on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, results of operations and financial condition would be materially and adversely affected.

As a result of the above, in connection with AVAT’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s (“FASB”) Accounting Standards Update (“ASU”) 2014-15, Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management has determined that AVAT’s liquidity condition raises substantial doubt about AVAT’s ability to continue as a going concern through the twelve months from December 31, 2025.

Critical Accounting Estimates

Our financial statements and the accompanying notes thereto included elsewhere in this proxy statement/prospectus are prepared in accordance with U.S. GAAP and pursuant to the accounting rules and regulations of the SEC. The preparation of financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, costs and expenses and related disclosures. We base our estimates on assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from our estimates. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected.

Given our limited operating history, we currently do not have any critical accounting policies. See Note 3, Summary of Significant Accounting Policies, of AVAT’s financial statements included elsewhere in this proxy statement/prospectus for a description of our significant accounting policies.

Off-Balance Sheet Arrangements

Other than as otherwise described in this proxy statement/prospectus, we do not have any off-balance sheet arrangements that have, or are reasonably likely to have, a material current or future effect on our financial condition, changes in financial condition, revenues, expenses, results of operations, liquidity, capital expenditures or capital resources.

Recent Accounting Pronouncements

See “Recent Accounting Pronouncements” described in Note 3 of our financial statements included elsewhere in this proxy statement/prospectus.

Internal Control Over Financial Reporting

As a privately held company, we were not required to assess and conclude on the effectiveness of our internal control over financial reporting in a manner that meets the standards of publicly traded companies required by Section 404 of the Sarbanes-Oxley Act. However, during the preparation of our financial statements included elsewhere in this prospectus we identified a material weakness in our internal control over financial reporting. The PCAOB defines a material weakness as “a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis.”

222

We did not design or maintain an effective control environment commensurate with the financial reporting requirements applicable to U.S. listed companies, including adequate business processes, systems, personnel and related internal controls. As a result, we identified the following material weakness:

• We did not design and maintain effective controls over the financial reporting process, including segregation of duties related to journal entries and account reconciliations.

The material weakness described above did not result in a material misstatement to our financial statements. Nevertheless, we recognize that the material weakness described above could result in misstatements to one or more account balances or disclosures, including substantially all financial statement accounts and disclosures, that would result in a material misstatement to our annual or interim consolidated financial statements that would not be prevented or detected on a timely basis.

We are in the process of implementing measures designed to improve our internal control over financial reporting and remediate the control deficiencies that led to the material weakness:

• We will continue to formalize and enhance policies and procedures regarding the financial reporting process to support the effective deployment of management’s directives and control activities, including that we plan to design and implement control activities in response to the risks posed as a result of the lack of segregation of duties related to journal entries and account reconciliations, including general controls over information systems. We will clearly define responsibility and accountability for the timely execution of such policies and procedures. In parallel, we will continue to design, implement and refine a comprehensive set of controls over the financial consolidation and reporting process to support the accuracy, completeness and timeliness of our financial statements.

We will not be able to fully remediate this material weakness until the remediation plan described above has been fully implemented, the applicable controls have been operating for a sufficient period of time, and we have concluded, through testing, that the newly implemented and enhanced controls are operating effectively. We can give no assurance that the measures we have taken and plan to take in the future will remediate the material weakness in our internal control over financial reporting or that it will prevent or avoid potential future material weaknesses. In addition, our current internal control over financial reporting and disclosure controls and procedures, and any new internal control over financial reporting and disclosure controls and procedures that we develop, may become inadequate because of changes in our business, operations and other factors, some of which may be beyond our control. While we will work to remediate the material weakness as quickly and efficiently as possible, we cannot at this time provide an expected timeline in connection with any remediation plan. These remediation measures may be time-consuming and costly and might place significant demands on our financial and operational resources.

As permitted under the U.S. securities laws, neither we nor our independent registered public accounting firm have performed or are required to perform a formal evaluation of the effectiveness of our internal control over financial reporting pursuant to Section 404. It is possible that, had such an evaluation been performed, additional material weaknesses or significant deficiencies may have been identified, and we may identify further material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Any failure to maintain effective internal control over financial reporting could result in misstatements in our financial statements that could lead to a restatement of our financial statements, cause us to fail to meet our reporting obligations or adversely affect investor confidence in our reported financial and other information, which may result in a decline in the market price of our ordinary shares.

See the section titled “Risk Factors — We have identified a material weakness in our internal control over financial reporting. If remediation of this material weakness is not effective, if we experience additional material weaknesses, or if we otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report their financial condition or results of operations.”

Emerging Growth Company Status

AVAT is expected to be an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as to those standards apply to private companies. AVAT has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Quantitative and Qualitative Disclosures about Market Risk

The following discussion about our market risk exposures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements.

AVAX Market Price Risk

Our AVAX treasury assets will be measured using observed prices from active exchanges, which could result in volatility in our financial results in future periods. Adjustments are recorded in net income through “gain (loss) on digital assets” on the statements of operations. Therefore, negative swings in the market price of AVAX could have a material impact on our earnings and on the carrying value of our digital assets.

Custodian Risk

Following the Business Combination, Pubco’s AVAX will be held with third-party custodians, initially, which we select based on various factors, including their financial strength and industry reputation. Custodian risk refers to the potential loss, theft or misappropriation of our AVAX assets due to operational failures, cybersecurity breaches or financial difficulties experienced by these third parties. Although we periodically monitor the financial health, insurance coverage and security measures of our custodians, reliance on such third parties inherently exposes us to risks that we cannot fully mitigate.

Corporate Governance

Pubco will structure its corporate governance in a manner that MLAC and the Company believe will closely align its interests with those of its shareholders following the Business Combination. Notable features of this corporate governance include:

• Pubco will have independent director representation on its audit committee immediately at the time of consummation of the Business Combination;

• at least one of Pubco’s directors will qualify as an “audit committee financial expert” as defined by the SEC; and

• Pubco intends to implement a range of other corporate governance best practices, including implementing a robust director education program.

Composition of the Pubco Board After the Business Combination

Pubco’s business and affairs will be managed under the direction of the Pubco Board.

All members of the Pubco Board shall be elected for a one-year term and may be re-elected for successive terms.

For further information regarding the structure of the Pubco Board, see the sections entitled “Description of Pubco Securities.”

Director Independence; Controlled Company Exception

Because the Seller will hold all of the Pubco Class B Stock outstanding following the completion of the Business Combination, Pubco will be a “controlled company” under Nasdaq Rules. As a controlled company, Pubco will be exempt from certain Nasdaq governance requirements that would otherwise apply to the composition and function of the Pubco Board, and it intends to avail itself of such exemptions, in whole or in part, for so long as the Seller continues to hold a majority of the outstanding shares of Pubco Class B Stock. For example, Pubco will not be required to comply with certain rules that would otherwise require, among other things, (i) the Pubco Board to have a majority of independent directors, (ii) the compensation of Pubco’s executive officers to be determined by a majority of the independent directors or a committee of independent directors and (iii) director nominees to be selected or recommended either by a majority of the independent directors or a committee of independent directors.

For at least some period following the closing of the Business Combination, Pubco intends to utilize all of the exemptions available to controlled companies. If at any time Pubco ceases to be a controlled company, Pubco will take all action necessary to comply with the Nasdaq Rules, including appointing a majority of independent directors to the Pubco Board and ensuring Pubco’s audit committee, compensation committee and nominating and corporate governance committee are each composed entirely of independent directors, subject to any permitted “phase-in” periods.

227

If Pubco ceases to be a “controlled company” and its shares continue to be listed on Nasdaq, Pubco will be required to comply with these standards and, depending on the board’s independence determination with respect to its then-current directors, Pubco may be required to add additional directors to the Pubco Board in order to achieve such compliance within the applicable transition periods.

Board Committees

The Pubco Board will direct the management of Pubco’s business and affairs, as provided by Delaware law, and will conduct its business through meetings of the Pubco Board and standing committees. Following the Closing, Pubco will have a standing audit committee, nominating committee and compensation committee.

In addition, from time to time, special committees may be established under the direction of the Pubco Board when necessary to address specific issues.

Audit Committee

Pubco’s audit committee will be responsible for, among other things:

• appointing, compensating, retaining, evaluating, terminating and overseeing its independent registered public accounting firm;

• discussing with its independent registered public accounting firm their independence from management;

• reviewing, with its independent registered public accounting firm, the scope and results of their audit;

• approving all audit and permissible non-audit services to be performed by its independent registered public accounting firm;

• overseeing the financial reporting process and discussing with management and its independent registered public accounting firm the quarterly and annual financial statements that its files with the SEC;

• overseeing its financial and accounting controls and compliance with legal and regulatory requirements;

• reviewing its policies on risk assessment and risk management;

• reviewing related person transactions; and

• establishing procedures for the confidential anonymous submission of concerns regarding questionable accounting, internal controls or auditing matters.

The audit committee shall review and approve the declaration and issuance/payments of dividends or buybacks, capital expenditures exceeding an aggregate value of USD                  and perquisites.

228

Upon the consummation of the Business Combination, the members of Pubco’s audit committee are expected to be Paul Grinberg, Gerald Bartholomew Smith and Robert Hadick, each of whom are “financially literate” as defined under Nasdaq listing rules and the rules and regulations of the SEC. Paul Grinberg is expected to be the chair of the audit committee. Paul Grinberg qualifies as an “audit committee financial expert” within the meaning of SEC regulations and meets the financial sophistication requirements of the Nasdaq Rules. Pubco expects that the Pubco Board will determine that Mr. Grinberg is an “independent director” as defined in the Nasdaq Rules and the rules and regulations of the SEC and Gerald Bartholomew Smith and Robert Hadick will not be considered independent directors under Nasdaq Rules. Under applicable Nasdaq Rules, Pubco will be permitted to “phase-in” compliance with the independence requirements for its audit committee. The phase-in periods with respect to director independence will allow Pubco to have (i) only one independent member on its audit committee upon the consummation of the Business Combination, (ii) a majority of independent members on its audit committee within 90 days of the consummation of the Business Combination and (iii) a fully independent audit committee within one year of the consummation of the Business Combination. Pubco intends to take advantage of these phase-in rules with respect to each of Gerald Bartholomew Smith’s and Robert Hadick’s service on the audit committee. Pubco expects that by the first anniversary of its initial listing on Nasdaq, the audit committee will comply with the applicable independence requirements. The information on any of Pubco’s websites is deemed not to be incorporated in this proxy statement/prospectus or to be part of this proxy statement/prospectus.

Compensation Committee

Pubco’s compensation committee will be responsible for, among other things:

• reviewing and approving the corporate goals and objectives, evaluating the performance of and reviewing and approving the compensation of its Chief Executive Officer and other executive officers;

• administering any incentive compensation plans of the Company approved by the Pubco Board;

• reviewing and approving all employment agreement and severance arrangements for Pubco’s executive officers;

• making recommendations to the Pubco Board regarding the compensation of Pubco’s directors; and

• retaining and overseeing any compensation consultants.

Upon the consummation of the Business Combination, the members of Pubco’s compensation committee are expected to be Gerald Bartholomew Smith, Robert Hadick and Paul Grinberg. Gerald Bartholomew Smith is expected to be the chair of the compensation committee. The Pubco Board will adopt a written charter for the compensation committee, which will be available on Pubco’s corporate website at https://avat.com/ upon the completion of the Business Combination. The information on any of Pubco’s websites is deemed not to be incorporated in this proxy statement/prospectus or to be part of this proxy statement/prospectus.

Nominating & Governance Committee

Pubco’s nominating and governance committee will be responsible for, among other things:

• developing the criteria and qualifications for membership on the Pubco Board;

• recruiting, reviewing, nominating and recommending candidates for election to the Pubco Board or filling vacancies on the Pubco Board;

• reviewing candidates proposed by shareholders and conducting appropriate inquiries into the background and qualifications of any such candidates; and

• having such other powers and authority as the Board may provide by resolution.

Upon completion of the Business Combination, Pubco’s nominating and governance committee will consist of Sarkees John Nahas, Paul Grinberg and Gerald Bartholomew Smith with Sarkees John Nahas serving as chair.

229

The Pubco Board will adopt a written charter for the nominating and governance committee, which will be available on Pubco’s corporate website at https://avat.com/ upon the completion of the Business Combination. The information on any of Pubco’s websites is deemed not to be incorporated in this proxy statement/ prospectus or to be part of this proxy statement/prospectus.

Advisory Board

In addition to the Pubco Board, Pubco will have an Advisory Board consisting initially of four members, including Ava Labs founder and co-creator of the Avalanche Network, Emin Gün Sirer, managing partner of Dragonfly, Haseeb Qureshi, Blockworks Inc. Chief Executive Officer, Jason Yanowitz and Aave Labs Chief Executive Officer, Stani Kulechov.

Our Advisory Board members will support our long-term goals by offering strategic guidance based on their unique expertise, and will provide insight to management on key strategic decisions. We believe our Advisory Board members, through their unique credentials as leaders in the crypto industry and, in the case of Emin Gun Sirer, as co-creator of the Avalanche Network, will also assist in the identification of digital asset market trends, regulatory developments, technological advancements on the Avalanche Network and in the broader digital asset space and corporate development opportunities. As such our Advisory Board members will support us in anticipating changes in the digital asset landscape and adapting our strategy accordingly. Our Advisory Board members will also leverage their professional networks and experience to facilitate opportunities with potential partners, investors and stakeholders.

As full compensation for their advisory services, Advisory Board members will receive a number of restricted stock units equal to the number of Company Units that, immediately following the Closing, would convert into a number of shares of Pubco Class A Stock equal to 0.20% of the aggregate outstanding Pubco Stock on a fully diluted basis, as determined by the Pubco Board. The term of each Advisory Board member will begin at Closing and continue until terminated by Pubco or the respective advisor at any time and for any reason upon 60 days’ advance written notice.

Risk Oversight

Upon the Closing, one of the key functions of the Pubco Board will be informed oversight of Pubco’s risk management process. The Pubco Board does not anticipate having a standing risk management committee, but rather anticipates administering this oversight function directly through the Pubco Board as a whole, as well as through various standing committees of the Pubco Board that address risks inherent in their respective areas of oversight. In particular, the Pubco Board will be responsible for monitoring and assessing strategic risk exposure, and Pubco’s audit committee will have the responsibility to consider and discuss Pubco’s major financial risk exposures and the steps its management will take to monitor and control such exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The audit committee will also monitor compliance with legal and regulatory requirements. Pubco’s compensation committee will also assess and monitor whether Pubco’s compensation plans, policies and programs comply with applicable legal and regulatory requirements.

Code of Business Conduct and Ethics

Pubco will adopt a written code of business conduct and ethics that applies to its directors, officers and employees, including its principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of the code will be posted on Pubco’s corporate website at https://avat.com/ upon the completion of the Business Combination. The nominating and corporate governance committee of the Pubco will be responsible for overseeing the Code of Conduct and must approve any waivers of the Code of Conduct for employees, executive officers and directors. In addition, Pubco intends to post on Pubco’s website all disclosures that are required by law or the Nasdaq listing standards concerning any amendments to, or waivers from, any provision of the code. The information on any of Pubco’s websites is deemed not to be incorporated in this proxy statement/prospectus or to be part of this proxy statement/prospectus.

BENEFICIAL OWNERSHIP OF SECURITIES

The following table and accompanying footnotes set forth information regarding (i) the beneficial ownership of MLAC Ordinary Shares, as of May 5, 2026 and (ii) expected beneficial ownership of shares of Pubco Stock following completion of the Transactions, assuming both that the Public Shareholders validly elect to redeem no Public Shares and alternatively that the Public Shareholders validly elect to redeem all of the Public Shares. Prior to the Closing, the shareholders of the Company are Seller and Gerald Bartholomew Smith.

This ownership information is provided in respect of:

• each person who is the beneficial owner of more than 5% of the issued and outstanding MLAC Ordinary Shares;

• each of MLAC’s current executive officers and directors; all of MLAC’s current executive officers and directors as a group;

• each person expected to be the beneficial owner of more than 5% of the issued and outstanding shares of Pubco Stock after the completion of the Business Combination;

• each of Pubco’s current executive officers and directors;

• each person who is expected to become an executive officer or a director of Pubco upon completion of the Business Combination; and

• all of Pubco’s expected executive officers and directors as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days.

Pursuant to the MLAC Memorandum and Articles, each MLAC Ordinary Share entitles the holder to one vote per share, except as otherwise described herein. Pursuant to the Amended and Restated Certificate of Incorporation, each share of Pubco Class B Stock will entitle the holder to one vote per share. Each share of Pubco Class A Stock will not entitle the holder to vote on any matters except as required by law.

Beneficial ownership of MLAC Ordinary Shares prior to the completion of the Business Combination is based on 30,992,500 MLAC Ordinary Shares issued and outstanding as of the date of this proxy statement/prospectus.

The expected beneficial ownership of shares of Pubco Stock following completion of the Business Combination assumes two scenarios:

• No Redemptions: This scenario assumes no Public Shareholders exercise their redemption rights.

• Maximum Redemptions: This scenario assumes that all Public Shareholders choose to exercise their redemption rights in respect of the 22,905,484 Public Shares.

231

Both scenarios assume, among other things, (a) no shares of Pubco Class A Stock are issued pursuant to the Incentive Plan, (b) no Adjustment Units are issued pursuant to the Company Unit Subscription Agreements; (c) an Unrestricted Signing AVAX Price of $29.62, Long Restricted Signing AVAX Price of $22.22 and Short Restricted Signing AVAX Price of $25.18; (d) consummation of the Transactions in accordance with the Business Combination Agreement; and (e) following the Closing, Pubco will have outstanding 60,468,670 shares of Pubco Class A Stock, including (i) up to 3,000,000 Pubco Class A Stock to be issued to the Foundation pursuant to the Foundation Transaction, (ii) 5,805,638 Pubco Class A Stock to be issued to the Seller Related Parties pursuant to the Seller Related Parties receiving one share of Pubco Class A Stock for each Company Unit held, (iii) the 2,000,000 Pubco Class A Stock to be issued to Astral as additional consideration for the Company Merger, (iv) the 2,800,000 Pubco Class A Stock to be issued to the Sponsor and Affiliates in exchange for MLAC Founder Shares, (v) the 25,300,000 Pubco Class A Stock pursuant to Public Shareholders receiving one (1) share of Pubco Class A Stock for each MLAC Class A Ordinary Share held by such shareholder, including the 2,300,000 Pubco Class A Stock pursuant to each holder of MLAC Rights receiving one share of Pubco Class A Stock in exchange for every ten (10) MLAC Rights held by such holder, and (vi) the 21,563,032 Pubco Class A Stock pursuant to each Company Member other than Seller receiving one share of Pubco Class A Stock for each Company Unit held immediately prior to the effective time of the Company Merger.

The beneficial ownership information below also assumes that the number of outstanding securities and securities convertible or exercisable within 60 days of May 5, 2026 of each of MLAC and Pubco are the same as the number of such securities outstanding upon consummation of the Business Combination. Based on the foregoing assumptions, we estimate that there would be 60,468,670 shares of Pubco Class A Stock issued and outstanding immediately following the consummation of the Business Combination in the “No Redemptions” scenario, and 37,563,186 shares of Pubco Class A Stock issued and outstanding following the consummation of the Business Combination in the “Maximum Redemptions” scenario. If the actual facts are different from the foregoing assumptions, ownership figures in Pubco and the columns under “No Redemptions” and “Maximum Redemptions” in the table that follows will be different.

Unless otherwise noted in the footnotes to the following table, and subject to applicable community property laws, the persons and entities named in the table have sole voting and investment power with respect to their beneficially owned securities. Except as indicated in the footnotes to the table, each of the security holders listed below has sole voting and investment power with respect to MLAC Ordinary Shares or shares of Pubco Stock owned by such shareholders.

Pre-Business Combination Beneficial Ownership Table of MLAC

The following table sets forth information regarding the beneficial ownership of MLAC Ordinary Shares as of May 5, 2026, based on information obtained from the persons named below, with respect to the beneficial ownership of MLAC Ordinary Shares, by:

• each person known by MLAC to be the beneficial owner of more than 5% of outstanding MLAC Ordinary Shares;

On all matters to be voted upon, except for the election of directors of the MLAC Board or continuing MLAC outside of the Cayman Islands, holders of the MLAC Class A Ordinary Shares and MLAC Class B Ordinary Shares vote together as a single class, unless otherwise required by applicable law.

Employment Agreements

The Company has entered into amended offer letters with each of its named executive officers which are expected to be assigned to Pubco at the Closing.

The summaries are not a complete description of all provisions of the offer letters and are qualified in their entirety by reference to the written offer letters and the amendments to the offer letters, each of which is filed as an exhibit to the registration statement of which this prospectus is a part.

Each of the offer letters provides for an annual base salary, annual target bonus opportunity based upon achievement of Company performance goals, sign-on bonus and equity grants under the Incentive Plan, the terms of which are described under “— Anticipated Equity Awards” below.

Anticipated Incentive Plan

Prior to the Closing, Pubco intends to approve and adopt the Incentive Plan, the material terms of which are described under “— Material Terms of the Incentive Plan” below.

Anticipated Equity Awards

In connection with the Closing, Pubco intends to grant restricted stock units with respect to shares of Pubco Class A Common Stock (“RSUs”) and performance-based RSUs (“PSUs”) under the Incentive Plan to Pubco’s named executive officers in accordance with the terms described below.

Restricted Stock Units

Pubco intends to grant to Mr. Smith and Ms. Mihalchick Moljo a number of RSUs with a grant date value equal to $7,500,000 and $2,000,000, respectively. The number of RSUs expected to be granted to Mr. Smith and Ms. Mihalchick Moljo will be adjusted upward if the Closing AVAX Price is greater than the Unrestricted Signing AVAX Price in the same ratio as applicable to Company Units as described under “The Business Combination Proposal — Other Transaction Agreements — The Company Unit Subscription Agreements.” Mr. Smith’s RSUs will time-vest over three years on each six-month anniversary of October 1, 2025, Ms. Mihalchick Moljo’s RSUs will time-vest over two years on each six-month anniversary of October 1, 2025, in each case, subject to the Closing and continued employment with Pubco or its subsidiaries on the applicable vesting date.

If Mr. Smith’s or Ms. Mihalchick Moljo’s employment terminates due to death or disability or is terminated by the Company or Pubco, as applicable, without cause or due to Mr. Smith’s or Ms. Mihalchick Moljo’s resignation for Good Reason (as each such term is defined in their respective offer letters, as amended), all unvested RSUs that would have vested during the six-month period following the executive’s termination date will accelerate and vest as of the termination date.

Performance-Based RSUs

Pubco intends to grant to Mr. Smith and Ms. Mihalchick Moljo a number of PSUs with a grant date value equal to $9,000,000 and $2,500,000, respectively. The PSUs will vest upon satisfaction of the time-vesting conditions applicable to the RSUs granted to each of Mr. Smith and Ms. Mihalchick Moljo and achievement of certain stock price-based performance goals prior to October 1, 2030, in the case of Mr. Smith, or October 1, 2028, in the case of Ms. Mihalchick Moljo, subject, in each case, to the Closing and continued employment with the Company or Pubco, as applicable, on the applicable vesting date.

If Mr. Smith’s or Ms. Mihalchick Moljo’s employment terminates due to death or disability or is terminated by the Company or Pubco, as applicable, without cause or due to Mr. Smith’s or Ms. Mihalchick Moljo’s resignation for Good Reason (as each such term is defined in their respective offer letters, as amended), all then-unvested PSUs will remain outstanding and eligible to vest subject to the satisfaction of the performance-vesting conditions during the six-month period following the executive’s termination date.

238

Material Terms of the Incentive Plan

The material terms of the Incentive Plan, as currently contemplated by Pubco, are summarized below. Pubco is still in the process of developing, approving and implementing the Incentive Plan and, accordingly, there can be no assurance that the Incentive Plan will be implemented or will contain the terms described below. Accordingly, this summary is subject to change.

Number of Shares Authorized

A number of shares of Pubco Class A Stock equal to 11% of the total outstanding shares of Pubco Class A Stock as of the Closing on a fully diluted basis will be reserved and available for issuance under the Incentive Plan. The maximum number of shares of Pubco Class A Stock reserved for issuance under the Incentive Plan will be subject to an annual increase on January 1 of each year during the term of the Incentive Plan, beginning on and including January 1, 2027, and ending on and including January 1, 2035, equal to the lesser of (x) 5% of the aggregate number of shares of Pubco Class A Stock issued and outstanding on December 31 of the immediately preceding year and (y) such smaller number of shares of Pubco Class A Stock as is determined by the compensation committee of the Pubco Board (the “Plan Administrator”).

Shares of Pubco Class A Stock subject to an award under the Incentive Plan that remain unissued upon the cancellation, termination or expiration of the award will again become available for grant under the Incentive Plan. In addition, shares of Pubco Class A Stock that are exchanged by a participant or withheld by Pubco as full or partial payment in connection with any award under the Incentive Plan, as well as any shares of Pubco Class A Stock exchanged by a participant or withheld by Pubco to satisfy the tax withholding obligations related to any award, will again be available for subsequent awards under the Incentive Plan. Furthermore, to the extent an award is paid or settled in cash or digital assets, the number of shares of Pubco Class A Stock previously subject to the award will again be available for grants pursuant to the Incentive Plan, and to the extent that an award can only be settled in cash or digital assets, such award will not be counted against the total number of shares of Pubco Class A Stock available for grant under the Incentive Plan.

Administration

The Plan Administrator may interpret the Incentive Plan and may prescribe, amend and rescind rules and make all other determinations necessary or desirable for the administration of the Incentive Plan. The Incentive Plan permits the Plan Administrator to select the officers, employees, non-employee directors, independent contractors and consultants who will receive awards, to determine the terms and conditions of those awards, including but not limited to the exercise price or other purchase price of an award, the number of shares of Pubco Class A Stock or cash, digital assets or other property subject to an award, the term of an award and the vesting schedule applicable to an award, and to amend the terms and conditions of outstanding awards.

RSUs and Restricted Stock

RSUs and restricted stock may be granted under the Incentive Plan. The Plan Administrator will determine the purchase price, vesting schedule and performance objectives, if any, applicable to the grant of RSUs and restricted stock. If the restrictions, performance objectives or other conditions determined by the Plan Administrator are not satisfied, the RSUs and restricted stock will be forfeited. Subject to the provisions of the Incentive Plan and the applicable individual award agreement, the Plan Administrator may provide for the lapse of restrictions in installments or the acceleration or waiver of restrictions (in whole or part) under certain circumstances as set forth in the applicable individual award agreement, including the attainment of certain performance goals, a participant’s termination of employment or service, or a participant’s death or disability. The rights of RSU and restricted stockholders upon a termination of employment or service will be set forth in individual award agreements.

Unless the applicable award agreement provides otherwise, participants with restricted stock will generally have all of the rights of a stockholder during the restricted period, including the right to vote and receive dividends declared with respect to such restricted stock. Any dividends declared during the restricted period with respect to such restricted stock will, to the extent set forth in the applicable award agreement, be payable either currently, at the time (and to the extent) that the underlying shares of restricted stock vest, or in the form of additional shares of restricted stock that are subject to the same vesting and other terms and conditions as the underlying shares of restricted stock. During the restricted period, participants with RSUs will generally not have any rights of a stockholder, but, if the applicable individual award agreement so provides, may be credited with dividend equivalent rights either currently, at the time (and to the extent) that the shares of Pubco Class A Stock related to such awards are delivered to the participant, or in the form of additional awards that are subject to the same vesting and other terms and conditions as the original awards.

239

Stock Options

Pubco may issue stock options under the Incentive Plan. Options granted under the Incentive Plan may be in the form of non-qualified options or “incentive stock options” within the meaning of Section 422 of the Code, as set forth in the applicable individual option award agreement. The exercise price of all options granted under the Incentive Plan will be determined by the Plan Administrator, but in no event may the exercise price be less than 100% of the fair market value of the related shares of Pubco’s Class A Stock on the date of grant. The maximum term of all stock options granted under the Incentive Plan will be determined by the Plan Administrator but may not exceed ten years. Each stock option will vest and become exercisable (including in the event of the optionee’s termination of employment or service) at such time and subject to such terms and conditions as determined by the Plan Administrator in the applicable individual option agreement.

Stock Appreciation Rights

Stock appreciation rights (“SARs”) may be granted under the Incentive Plan either alone or in conjunction with all or part of any option granted under the Incentive Plan. A free-standing SAR granted under the Incentive Plan entitles its holder to receive, at the time of exercise, an amount per share equal to the excess of the fair market value (at the date of exercise) of a share of Pubco Class A Stock over the base price of the free-standing SAR. A SAR granted in conjunction with all or part of an option under the Incentive Plan entitles its holder to receive, at the time of exercise of the SAR and surrender of the related option, an amount per share equal to the excess of the fair market value (at the date of exercise) of a share of Pubco Class A Stock over the exercise price of the related option. Each SAR will be granted with a base price that is not less than 100% of the fair market value of the related shares of Pubco Class A Stock on the date of grant. The maximum term of all SARs granted under the Incentive Plan will be determined by the Plan Administrator but may not exceed ten years. The Plan Administrator may determine to settle the exercise of a SAR in shares of Pubco Class A Stock, cash, digital assets or any combination thereof.

Each free-standing SAR will vest and become exercisable (including in the event of the SAR holder’s termination of employment or service) at such time and subject to such terms and conditions as determined by the Plan Administrator in the applicable individual free-standing SAR agreement. SARs granted in conjunction with all or part of an option will be exercisable at such times and subject to all of the terms and conditions applicable to the related option.

Other Stock-Based, Cash and Digital Asset Awards

Other stock-based awards, valued in whole or in part by reference to, or otherwise based on, shares of Pubco Class A Stock (including dividend equivalents) may be granted under the Incentive Plan. The Plan Administrator will determine the terms and conditions of such other stock-based awards, including the number of shares of Pubco Class A Stock to be granted pursuant to such other stock-based awards, the manner in which such other stock-based awards will be settled (e.g., in shares of Pubco Class A Stock or cash, digital assets or other property), and the conditions to the vesting and payment of such other stock-based awards (including the achievement of performance objectives).

Bonuses payable in fully vested shares of Pubco Class A Stock and awards that are payable solely in cash or digital assets may also be granted under the Incentive Plan.

Change in Control

In the event of a merger, consolidation, reclassification, recapitalization, spin-off, spin-out, repurchase, reorganization, corporate transaction or event, special or extraordinary dividend or other extraordinary distribution (whether in the form of shares of Pubco Class A Stock, cash, digital assets or other property), stock split, reverse stock split, subdivision or consolidation, combination, exchange of shares, or other change in corporate structure affecting the shares of Pubco Class A Stock, an equitable substitution or proportionate adjustment shall be made, at the sole discretion of the Plan Administrator, in (i) the aggregate number of shares of Pubco Class A Stock reserved for issuance under the Incentive Plan, (ii) the kind and number of securities subject to, and the exercise price or base price of, any outstanding options and SARs granted under the Incentive Plan, (iii) the kind, number and purchase price of shares of Pubco Class A Stock, or the amount of cash or amount or type of digital assets or other property, subject to outstanding restricted stock, RSUs, stock bonuses and other stock-based awards granted under the Incentive Plan or (iv) the performance goals and periods applicable to awards granted under the Incentive Plan. Equitable substitutions or adjustments other than those listed above may also be made as determined by the Plan Administrator.

240

Except as provided in the applicable award agreement, if a change in control occurs and an award is not assumed, substituted or cancelled in connection with the change in control, then: (i) any unvested or exercisable portion of any award carrying a right to exercise will become fully vested and exercisable and (ii) the restrictions, deferral limitations, payment conditions and forfeiture conditions applicable to any awards will lapse and such awards will be deemed fully vested and any performance conditions imposed with respect to the awards will be deemed to be achieved at the greater of target and actual performance levels as of the date of the change in control. If a change in control occurs and an award is assumed or substituted in connection with the change in control, then the award will remain outstanding and will continue to vest following the change in control in accordance with its terms and subject to adjustment in accordance with the Incentive Plan.

For purposes of any outstanding awards under the Incentive Plan, a “change in control” means (i) any person becoming the beneficial owner of securities representing 50% or more of the combined voting power of Pubco’s then-outstanding securities, (ii) the directors serving on the Pubco Board as of the effective date of the Incentive Plan, or directors whose appointment by the Pubco Board was approved or recommended by a vote of at least two-thirds of the directors then still in office who either were directors on the effective date or whose appointment was previously so approved cease to constitute a majority of the number of directors then serving on the Pubco Board, (iii) a merger or consolidation of Pubco, other than (1) a merger or consolidation which results in the voting securities of Pubco outstanding immediately prior to such merger or consolidation continuing to represent more than 50% of the combined voting power of the securities of Pubco and individuals who comprise the Pubco Board immediately prior to the merger or consolidation constituting at least a majority of the board of directors of the surviving entity, or (2) a merger or consolidation effected to implement a recapitalization of Pubco or a similar transaction, or (iv) a liquidation or dissolution of Pubco or a consummated agreement for the sale or disposition by Pubco of all or substantially all of Pubco’s assets.

Withholding

Each participant will be required to make arrangements satisfactory to the Plan Administrator regarding payment of an amount up to the maximum statutory rates in the participant’s applicable jurisdictions with respect to any award granted under the Incentive Plan, as determined by us. Pubco has the right, to the extent permitted by law, to deduct any such taxes from any payment of any kind otherwise due to the participant. With the approval of the Plan Administrator, the participant may satisfy the foregoing requirement by either electing to have Pubco withhold from delivery of shares of Pubco Class A Stock, cash, digital assets or other property, as applicable, or by delivering already owned unrestricted shares of Pubco Class A Stock, in each case, having a value not exceeding the applicable taxes to be withheld and applied to the tax obligations. Pubco may also use any other method of obtaining the necessary payment or proceeds, as permitted by law, to satisfy Pubco’s withholding obligation with respect to any award, including pursuant to an arrangement whereby a certain number of shares of Pubco Class A Stock issued pursuant to any award are immediately sold and proceeds from such sale are remitted to Pubco or its subsidiaries in an amount that would satisfy the withholding amount due.

Amendment and Termination

The Incentive Plan provides the Plan Administrator with the authority to amend, alter or terminate the Incentive Plan, but no such action may impair the rights of any participant with respect to outstanding awards without the participant’s consent. The Plan Administrator may amend an award, prospectively or retroactively, but no such amendment may impair the rights of any participant without the participant’s consent. Stockholder approval of any such action will be obtained if required to comply with applicable law.

The Incentive Plan will terminate on the tenth anniversary of the effective date of the Incentive Plan (although awards granted before that time will remain outstanding in accordance with their terms).

241

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

MLAC’s Relationships and Related Party Transactions

MLAC Class B Ordinary Shares

On June 27, 2024, the Sponsor made a capital contribution of $25,000 to cover certain expenses on behalf of MLAC in exchange for issuance of the MLAC Class B Ordinary Shares. Subsequently, on December 12, 2024, MLAC, through a share capitalization, issued an additional 359,375 MLAC Class B Ordinary Shares to the Sponsor, resulting in an aggregate of 7,546,875 MLAC Class B Ordinary Shares issued and outstanding. The holders of the MLAC Class B Ordinary Shares agreed to forfeit and cancel up to an aggregate of 984,375 MLAC Class B Ordinary Shares, on a pro rata basis, to the extent that the option to purchase additional MLAC Units is not exercised in full by the underwriters. The forfeiture will be adjusted to the extent that the option to purchase additional MLAC Units is not exercised in full by the underwriters so that the MLAC Class B Ordinary Shares will represent approximately 23.2% of all of MLAC’s issued and outstanding shares after the Initial Public Offering. On December 16, 2024, the underwriters partially exercised their over-allotment option as part of the closing of the Initial Public Offering and forfeited their option to exercise the remaining over-allotment option. As such, 359,375 MLAC Class B Ordinary Shares were forfeited and resulted in a total number of 7,187,500 MLAC Class B Ordinary Shares outstanding.

With certain limited exceptions, the MLAC Class B Ordinary Shares are not transferable, assignable or salable (except to MLAC’s officers and directors and other persons or entities affiliated with the Sponsor, each of whom will be subject to the same transfer restrictions) until the earlier to occur of (i) one year after the completion of the initial Business Combination or (ii) the date on which MLAC completes a liquidation, merger, share exchange or other similar transaction after the initial Business Combination that results in all of the shareholders having the right to exchange their MLAC Class A Ordinary Shares for cash, securities or other property; except to certain permitted transferees and under certain circumstances as described herein. Any permitted transferees will be subject to the same restrictions and other agreements of the initial shareholders with respect to any MLAC Class B Ordinary Shares. Notwithstanding the foregoing, if (1) the closing price of the MLAC Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination or (2) if MLAC consummates a transaction after the initial Business Combination which results in the shareholders having the right to exchange their shares for cash, securities or other property, the MLAC Founder Shares will be released from the lock-up.

MLAC Private Placement Shares

Simultaneously with the closing of the MLAC IPO, the Sponsor and BTIG purchased an aggregate of 805,000 MLAC Private Placement Shares (495,000 MLAC Private Placement Shares purchased by the Sponsor and 310,000 MLAC Private Placement Shares purchased by BTIG), at a price of $10.00 per MLAC Private Placement Share from MLAC in a private placement, generating gross proceeds of $8,050,000. A portion of the proceeds from the sale of the MLAC Private Placement Shares were added to the net proceeds from the MLAC IPO held in the Trust Account. If MLAC does not complete a Business Combination within the Combination Period, the proceeds from the sale of the MLAC Private Placement Shares held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law). The MLAC Private Placement Shares are identical to the units sold in the MLAC IPO, except that the MLAC Private Placement Shares (including the MLAC Rights or MLAC Ordinary Shares issuable upon conversion of the MLAC Rights) will not be transferable, assignable or salable until 30 days after the completion of MLAC’s initial business combination.

Related Party Loans

On June 27, 2024, the Sponsor agreed to loan MLAC up to $200,000 (as amended to $300,000 on September 23, 2024) pursuant to a promissory note (the “IPO Note”). The IPO Note is non-interest bearing, unsecured and due on the earlier of December 31, 2024, the closing of the MLAC IPO, or the date MLAC determines not to proceed with the MLAC IPO. On December 31, 2024, MLAC repaid the total outstanding balance of the IPO Note amounting to $275,193. Borrowings under the IPO Note are no longer available.

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor, members of MLAC’s founding team or any of their affiliates may, but are not obligated to, loan MLAC funds as may be required (“MLAC Working Capital Loans”). If MLAC completes a Business Combination, MLAC would repay the MLAC Working Capital Loans out of the proceeds of

242

the Trust Account released to MLAC. Otherwise, the MLAC Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, MLAC may use a portion of proceeds held outside the Trust Account to repay the MLAC Working Capital Loans but no proceeds held in the Trust Account would be used to repay the MLAC Working Capital Loans. The MLAC Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1.5 million of such MLAC Working Capital Loans may be converted into MLAC Private Placement Shares at a price of $10.00 per unit. Except for the foregoing, the terms of such MLAC Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of December 31, 2025 and December 31, 2024, MLAC had no borrowings under the MLAC Working Capital Loans.

Registration Rights Agreement

The holders of the MLAC Founder Shares, MLAC Private Placement Shares (and underlying securities) and any MLAC Private Placement Shares (and underlying securities) that may be issued on conversion of MLAC Working Capital Loans are entitled to registration rights pursuant to a registration rights agreement requiring MLAC to register such securities for resale. The holders of these securities will be entitled to make up to three demands, excluding short form registration demands, that MLAC registers such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination and rights to require MLAC to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that MLAC will not be required to effect or permit any registration or cause any registration statement to become effective until termination of the applicable lock-up period. MLAC will bear the expenses incurred in connection with the filing of any such registration statements. In connection with the Business Combination, MLAC, the Sponsor, Pubco, the Seller, Avalanche BVI, Avalanche Cayman and certain securityholders will enter into the Amended and Restated Registration Rights Agreement which will amend and restate this registration rights agreement as further described elsewhere.

MLAC’s Related Party Transaction Policy

The audit committee of the MLAC Board has adopted a policy setting forth the policies and procedures for its review and approval or ratification of “related party transactions.” A “related party transaction” is any consummated or proposed transaction or series of transactions: (i) in which the company was or is to be a participant; (ii) the amount of which exceeds (or is reasonably expected to exceed) the lesser of $120,000 or 1% of the average of the company’s total assets at year end for the prior two completed fiscal years in the aggregate over the duration of the transaction (without regard to profit or loss); and (iii) in which a “related party” had, has or will have a direct or indirect material interest. “Related parties” under this policy will include: (i) the directors, nominees for director or executive officers; (ii) any record or beneficial owner of more than 5% of any class of the voting securities; (iii) any immediate family member of any of the foregoing if the foregoing person is a natural person; and (iv) any other person who maybe a “related person” pursuant to Item 404 of Regulation S-K under the Exchange Act. Pursuant to the policy, the audit committee will consider (i) the relevant facts and circumstances of each related party transaction, including if the transaction is on terms comparable to those that could be obtained in arm’s-length dealings with an unrelated third party, (ii) the extent of the related party’s interest in the transaction, (iii) whether the transaction contravenes MLAC’s Code of Ethics or other policies, (iv) whether the audit committee believes the relationship underlying the transaction to be in the best interests of the company and its shareholders and (v) the effect that the transaction may have on a director’s status as an independent member of the board and on his or her eligibility to serve on the board’s committees. MLAC’s management will present to the audit committee each proposed related party transaction, including all relevant facts and circumstances relating thereto. Under the policy, MLAC may consummate related party transactions only if its audit committee approves or ratifies the transaction in accordance with the guidelines set forth in the policy. The policy will not permit any director or executive officer to participate in the discussion of, or decision concerning, a related person transaction in which he or she is the related party.

243

The Company’s Relationships and Related Party Transactions

Policies and Procedures for Related Persons Transactions

Effective upon the Closing, the Pubco Board will adopt a written conflicts policy that will set forth the following policies and procedures for the review and approval or ratification of related person transactions to which the Company, as subsidiary of Pubco, will be subject. A “related person transaction” is a transaction, arrangement or relationship in which Pubco or any of its subsidiaries (including the Company) was, is or will be a participant, the amount of which involved exceeds $120,000 (or, for so long as Pubco remains a “smaller reporting company” the lesser of (i) $120,000 and (ii) 1% of Pubco’s average total assets of the two completed fiscal years), and in which any related person had, has or will have a direct or indirect material interest. A “related person” means:

• any person who is, or at any time during the applicable period was, one of Pubco’ executive officers or directors;

• any person who is known by Pubco to be the beneficial owner of more than 5% of Pubco voting stock;

• any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of a director, executive officer or a beneficial owner of more than 5% of Pubco’s voting stock, and any person (other than a tenant or employee) sharing the household of such director, executive officer or beneficial owner of more than 5% of Pubco’s voting stock; and

• any firm, corporation or other entity in which any of the foregoing persons is a partner or principal, or in a similar position, or in which such person has a 5% or greater beneficial ownership interest in Pubco Stock.

Pubco will have policies and procedures designed to minimize potential conflicts of interest arising from any dealings it may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time. Specifically, pursuant to its audit committee charter, the audit committee will have the responsibility to review related party transactions.

DESCRIPTION OF PUBCO SECURITIES

As a result of the Mergers and pursuant to the Business Combination Agreement, (i) MLAC Shareholders (including the Sponsor and its Affiliates and MLAC Right Holders) will receive shares of Pubco Class A Stock in the MLAC Merger and will become Pubco shareholders, (ii) the Funds will receive shares of Pubco Class A Stock and Pubco Class B Stock in the Company Merger, (iii) Astral will receive the Additional Merger Consideration Shares in the Company Merger, and (iv) the Company Unit Investors will receive shares of Pubco Class A Stock in the Company Merger.

The following description summarizes the terms of Pubco’s capital stock but does not purport to be complete, and it is qualified in its entirety by reference to the applicable provisions of Delaware law and the Proposed Organizational Documents. The Proposed Organizational Documents are filed as exhibits to the registration statement of which this joint proxy statement/prospectus forms a part. Unless otherwise indicated, this description applies to Pubco Stock following the Business Combination.

Authorized Capital Stock

Pubco’s currently authorized capital stock consists of one thousand (1,000) shares of common stock, par value $0.01 per share. If the proposals comprising the Domestication and Organizational Documents Proposals are approved, the authorized capital stock of Pubco will consist of 700,000,000 shares of common stock, par value $0.01 per share, which shall include 550,000,000 shares of Pubco Class A Stock, 100,000,000 shares of Pubco Class B Stock and 50,000,000 shares of preferred stock. All outstanding shares of Pubco capital stock are fully paid and non- assessable.

Pubco Stock

Voting Rights. Holders of Pubco Class A Stock will not be entitled to vote on any matters voted on by shareholders, except as required by the DGCL, until all shares of Pubco Class B Stock are canceled.

In particular, pursuant to Section 242 of the DGCL (as interpreted by case law), until all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock, (i) are entitled to vote, as a separate class, exclusively on any proposed amendment to the Pubco Charter that would adversely affect the powers, preferences or rights of holders of Pubco Class A Stock that are unique to such class (such as their economic rights), and (ii) are not entitled to vote on any other matters (including, inter alia, the election of directors, the decision to bring suit against directors, etc). In respect of the matters under point (i) above that are voted on by holders of Pubco Class A Stock, each holder of Pubco Class A Stock would be entitled to one (1) vote for each share held of record as of the applicable record date relating to such matter, and the approval of a majority of the outstanding shares of Pubco Class A Stock is required, in each case, as set forth in the Amended and Restated Pubco Charter and the DGCL.

Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights.

Each holder of Pubco Class B Stock is entitled to one (1) vote for each share held of record as of the record date on all matters voted on by shareholders, including the election of directors.

The Pubco Board is elected annually, and each director holds office for the term for which he or she is elected and until his or her successor is elected and qualified, except in the case of his or her death, resignation, removal or disqualification, and pursuant to the terms and conditions set forth in the Proposed Organizational Documents.

Dividend Rights. Holders of shares of Pubco Class A Stock are entitled to dividends when, as and if declared by the Pubco Board out of funds legally available therefor, subject to any preferential or other rights of any outstanding Pubco preferred stock. Holders of shares of Pubco Class B Stock are not entitled to dividends.

246

Transferability. Shares of Pubco Class A Stock will be freely transferable, subject to any restrictions pursuant to the DGCL and applicable federal securities laws. Transfers of shares of Pubco Class A Stock held by the Seller Related Parties, Astral, the Sponsor, and certain MLAC Insiders will be subject to the lock-up restrictions pursuant the Lock-Up Agreements and the Insider Letter, respectively. Shares of Pubco Class B Stock will not be freely transferable, except to an Affiliate of an holder of shares of Pubco Class B Stock (i.e., Seller Related Partes, at Closing) in accordance with the terms of the Amended and Restated Pubco Charter and the Amended and Restated Pubco By-laws. If a holder of shares of Pubco Class B Stock transfers any of its shares of Pubco Class A Stock to third parties other than their respective Affiliates, such that as a result of such transfer, said transferor would hold a number of shares of Pubco Class B Stock greater than the number of shares of Pubco Class A Stock it holds, then said excess shares of Pubco Class B Stock shall be automatically cancelled for no consideration concurrently with such transfer, so that immediately following such transfer, the number of shares of Pubco Class B Stock held by said transferor equals the number of shares of Pubco Class A Stock held by the same transferor.

Liquidation and Dissolution Rights. Subject to applicable law, upon liquidation, dissolution or winding up of Pubco’s affairs, holders of shares of Pubco Class A Stock will be entitled to receive pro rata on a share-for-share basis, the assets available for distribution after payment of liabilities and payment of preferential and other amounts, if any, payable on any outstanding convertible notes or preferred stock. Holders of shares of Pubco Class B Stock are not entitled to liquidating distributions.

Exclusive Jurisdiction. The Amended and Restated Pubco Charter includes an exclusive forum clause designating a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between Pubco and stockholders. The exclusive forum provision in the Amended and Restated Pubco Charter will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. See “Risk Factors — Risks Relating to Ownership of Pubco Stock Following the Business Combination — The Amended and Restated Pubco Charter designates a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between us and our stockholders, and also provides that the federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, each of which may limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers, stockholders, or employees.”

Other. Pubco Stock has no preemptive, subscriptive or conversion rights and is not entitled to the benefits of any redemption or sinking fund provision. Because Pubco Class A Stock is non-voting, holders of Pubco Class A Stock may have access to more limited information than holders of Pubco Class B Stock. See “Risk Factors — Risks Relating to Ownership of Pubco Stock Following the Business Combination — Because Pubco Class A Stock is non-voting, we and our stockholders are exempt from certain provisions of U.S. securities laws. This may limit the information available to holders of Pubco Class A Stock.”

Delaware Anti-Takeover Statute

A number of provisions of Delaware law, the Amended and Restated Certificate of Incorporation and the Amended and Restated Bylaws could have an anti-takeover effect and make more difficult the acquisition of Pubco by means of a tender offer, a proxy contest, or otherwise, and the removal of its directors or management. These provisions are intended to discourage coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of Pubco to negotiate first with its board of directors.

As a Delaware corporation, Pubco will be subject to Section 203 of the DGCL regarding corporate takeovers. In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” (as each term is defined in Section 203 of the DGCL) for a period three years following the time the person became an interested shareholder.

However, Section 203 does not apply in the following circumstances:

• If prior to the date of the transaction, the Board of Directors of such a Delaware corporation approved either the business combination or the transaction that resulted in the person becoming an interested stockholder;

247

• If, upon completion of the transaction that resulted in the person becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time such transaction commenced, excluding, for purposes of determining the number of shares outstanding (but not the outstanding number of shares owned by the interested stockholders), (a) shares owned by persons who are directors and also officers of the corporation and (b) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

• If, on or subsequent to such time, the business combination is approved by the board of directors of such corporation and authorized at a meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock of such corporation not owned by the interested stockholder.

A “business combination” generally includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is generally any person, and their associates and Affiliates, who owns or, within three years prior to the determination of interested stockholder status owned, 15% or more of a corporation’s outstanding voting stock. The existence of this provision would be expected to have an anti-takeover effect with respect to transactions not approved in advance by our Board of Directors, including discouraging attempts that might result in a premium over the market price for the shares of Pubco Class A Stock held by our stockholders.

A Delaware corporation may “opt out” of Section 203 with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from amendments approved by holders of at least a majority of the corporation’s outstanding voting shares. We will not elect to “opt out” of Section 203. However, following this offering and subject to compliance with Delaware law, our organizational documents and any contractual restrictions, we could subsequently elect to “opt out” of Section 203 by such an amendment to our certificate of incorporation or bylaws.

Limitation of Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors or officers to corporations and their stockholders for monetary damages for certain breaches of fiduciary duties as directors or officers, subject to exceptions. Amended and Restated Certificate of Incorporation includes such an exculpation provision.

The Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws include provisions that indemnify, to the fullest extent allowable under the DGCL, the personal liability of directors or officers for certain costs and losses for actions taken as Pubco’s director or officer, or for serving at Pubco’s request as a director or officer or another position at another corporation or enterprise, as the case may be, subject to exceptions and limitations. Amended and Restated Bylaws also provide that Pubco must advance reasonable expenses to Pubco directors and officers, subject to Pubco’s receipt of an undertaking from the indemnified party as may be required under the DGCL. Amended and Restated Bylaws provide that Pubco shall purchase and maintain directors’ and officers’ liability insurance to protect Pubco and Pubco’s directors, officers and certain employees for some liabilities.

The limitation of liability and indemnification provisions in the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against Pubco’s directors and officers, even though such an action, if successful, might otherwise benefit Pubco and Pubco stockholders. However, these provisions will not limit or eliminate Pubco’s rights, or those of any stockholder, to seek non-monetary relief such as injunction or rescission in the event of a breach of a director’s or an officer’s fiduciary duty of care. The limitation of liability and indemnification provisions under Amended and Restated Certificate of Incorporation does not alter the liability of directors under the federal securities laws.

248

Governance of Pubco

Board Composition

The Pubco Board will select the chair of the Pubco Board from the independent directors on the Pubco Board, who will not have any special voting rights or casting vote in the event of a tie.

Transfer Agent and Registrar

The transfer agent and registrar for Pubco Stock will be Continental Stock Transfer & Trust Company.

Following the completion of the Mergers, the shares of Pubco Class A Stock will be listed and traded on the Nasdaq under the symbol “AVAT”.

COMPARISON OF SHAREHOLDERS’ RIGHTS

If the MLAC Merger is completed, MLAC Shareholders will receive shares of Pubco Class A Stock in the MLAC Merger and they will cease to be MLAC Shareholders. MLAC is incorporated under the laws of the Cayman Islands and Pubco is organized under the laws of the State of Delaware. The below is a summary of the material differences between (1) the current rights of MLAC Shareholders under Cayman Islands law and the MLAC Memorandum and Articles and (2) the rights of holders of Pubco Stock, post-Closing, under Delaware law and Pubco’s Proposed Organizational Documents, as in effect immediately following the Business Combination.

MLAC and Pubco believe that this summary describes the material differences between the rights of MLAC Shareholders as of the date of this proxy statement/prospectus and the rights of holders of Pubco Stock after the Business Combination; however, it does not purport to be a complete description of those differences. The summary is qualified in its entirety by reference to Pubco’s and MLAC’s governing documents, which we urge you to read carefully and in their entirety. Attached as Annex B to this proxy statement/prospectus is a copy of the form of the Amended and Restated Charter, and attached as Annex C to this proxy statement/prospectus is a copy of the form of Amended and Restated Bylaws. To find out where copies of these documents can be obtained, see the section entitled “Where You Can Find More Information” in this Form S-4.

Provision	Pubco (Post-Closing)	MLAC
Voting Rights:	Except on matters where the vote of the holders of Pubco Class A Stock is required by the DGCL, the holders of Pubco Class A Stock will not be entitled to vote on any matter coming before any meeting of shareholders, including, without limitation, the election of directors. However, if the holders of Pubco Class A Stock are required by the DGCL to vote on any matter, then each holder of Pubco Stock shall be entitled to one (1) vote per share upon such matter coming before any meeting of the shareholders. The holders of Pubco Class B Stock will be entitled to one (1) vote per share upon any matter coming before any meeting of shareholders where the vote of the holders of Pubco Class A Stock is not required.	Prior to the consummation of an initial business combination, only holders of MLAC Class B Ordinary Shares will have the right to vote on continuing MLAC in a jurisdiction outside the Cayman Islands (including any special resolution required to adopt new constitutional documents as a result of MLAC’s approving a transfer by way of continuation to a jurisdiction outside the Cayman Islands). Holders of MLAC Class A Ordinary Shares will not be entitled to vote on such matter during such time. Such provision of the MLAC Memorandum and Articles may only be amended if approved by a special resolution being a resolution passed by at least two-thirds of the votes cast by, or on behalf of, the MLAC Shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at a general meeting or by way of unanimous written resolution. With respect to any other matter submitted to a vote of MLAC Shareholders, including any vote in connection with its initial business combination, except as required by applicable law or stock exchange rule, holders of MLAC Class A Ordinary Shares and holders of MLAC Class B Ordinary Shares will vote together as a single class, with each share entitling the holder to one vote.

250

Provision	Pubco (Post-Closing)	MLAC
Preemptive Rights:	Pursuant to the DGCL, there are no preemptive rights unless expressly provided in the corporation’s certificate of formation.	MLAC Shareholders have no preemptive or other subscription rights.
Appraisal Rights and Dissenters’ Rights:	Pursuant to the DGCL, a stockholder of a publicly traded corporation has appraisal rights in connection with a merger unless the merger consideration is all stock in another publicly traded corporation or another exception applies.	Under section 238 of the Cayman Act, shareholders of a Cayman Islands company ordinarily have dissenters’ rights with respect to a statutory merger or consolidation. The Cayman Act prescribes when shareholder dissenters’ rights will be available and sets the limitations on such rights. Where such rights are available, shareholders are entitled to receive fair value for their shares.
Inspection of Books and Records:	Pursuant to the DGCL, any stockholder, upon written demand stating the purpose thereof and identifying the documents sought with precision, has the right during usual hours for business to inspect for any proper purpose, and to make copies and extracts from, the corporation’s stock ledger and other books and records.	MLAC directors shall determine whether and to what extent and at what times and places and under what conditions or regulations the accounts and books of MLAC or any of them shall be open to the inspection of members not being MLAC directors and no member (not being an MLAC director) shall have any right of inspecting any account or book or document of MLAC except as conferred by the Cayman Act or authorized by MLAC directors or by MLAC in general meeting. The MLAC Board may cause to be prepared and to be laid before MLAC in general meeting profit and loss accounts, balance sheets, group accounts (if any) and such other reports and accounts as may be required by the laws of the Cayman Islands.
Size of Board of Directors:	Amended and Restated Bylaws and Amended and Restated Certificate of Formation provide that the Pubco Board will consist of one (1) or more members as determined by the Pubco Board, each of whom shall be a natural person.	The MLAC Board shall consist of not less than one person, unless otherwise determined by MLAC in general meeting.
Classes of Directors/Term of Directors:	Pursuant to the DGCL, the directors of a corporation may, by the certificate of incorporation or bylaws, be divided into one, two or three classes. The Pubco Board is not so classified. Each director of Pubco shall hold office for a term of one (1) year and serve until his or her successors are duly elected and qualified or until his or her earlier death, resignation or removal.	The MLAC Board is made up of three classes, Class I, Class II and Class III. The number of directors in each class shall be as nearly equal as possible. The Class I directors shall stand appointed for a term expiring at MLAC’s first annual general meeting, the Class II directors shall stand appointed for a term expiring at MLAC’s second annual general meeting and the Class III directors shall stand appointed for a term expiring at MLAC’s third annual general meeting. Commencing at MLAC’s first annual general meeting, and at each annual general meeting thereafter, directors appointed to succeed those directors whose terms expire shall be appointed for a term of office to expire at the third succeeding annual general meeting after their appointment.

251

Provision	Pubco (Post-Closing)	MLAC
Election and Appointment of Directors:	Pursuant to the DGCL, directors are elected at an annual meeting or at a special meeting called for that purpose, or by written consent in lieu of a meeting.	Directors may be appointed by ordinary resolution of MLAC Shareholders. The MLAC directors may appoint any person to be a director, either to fill a vacancy or as an additional director provided that the appointment does not cause the number of directors to exceed any number fixed by or in accordance with the MLAC Memorandum and Articles as the maximum number of directors.
Vacancies on the Board of Directors:	Pursuant to the DGCL, unless otherwise provided in the certificate of incorporation or bylaws, vacancies on the board of directors may be filled (i) by a majority of the directors then in office, although less than a quorum, or by a sole remaining director; or (ii) whenever the holders of any class or classes of stock or series thereof are entitled to elect one (1) or more directors by the certificate of incorporation, by a majority of the directors elected by such class or classes or series thereof then in office, or by a sole remaining director so elected.	All directors shall hold office until the expiration of their respective terms of office and until their successors shall have been appointed and qualified. A director appointed to fill a vacancy resulting from the death, resignation or removal of a director shall serve for the remainder of the full term of the director whose death, resignation or removal shall have created such vacancy and until his successor shall have been appointed and qualified.
Removal of Directors:	Pursuant to the DGCL and subject to certain exemptions, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares entitled to vote at an election of directors.	Directors may be removed by ordinary resolution of MLAC Shareholders. The office of a director may vacated if: (a) the director gives notice in writing to MLAC that they resign the office of director; (b) the director is absent (without being represented by proxy) from three consecutive meetings of the MLAC Board without special leave of absence from the directors, and the directors pass a resolution that they have by reason of such absence vacated office; (c) the director dies, becomes bankrupt or makes any arrangement or composition with their creditors generally; (d) the director is found to be or becomes of unsound mind; or (e) all of the other directors (being not less than two in number) determine that the director should be removed as a director, either by a resolution passed by all of the other directors at a meeting of the directors duly convened and held in accordance with the MLAC Memorandum and Articles or by a resolution in writing signed by all of the other directors.

252

Provision	Pubco (Post-Closing)	MLAC
Amendments to the Organizational Documents:	Pursuant to the DGCL, amendments to the certificate of incorporation must be approved by the board of directors, which adopts a resolution setting forth the proposed amendment and declaring its advisability, and then submitted to the stockholders for approval. Unless a higher vote is required by the certificate of incorporation, approval generally requires the affirmative vote of a majority of the shares entitled to vote on the matter. In addition, holders of a particular class or series of stock are entitled to vote separately on an amendment if the amendment (i) increases or decreases the number of authorized shares of that class, (ii) changes the par value of those shares, or (iii) alters or changes the powers, preferences or special rights of those shares in a manner that adversely affects them. If only one or more series within a class is adversely affected, only the holders of that series are entitled to vote. Pursuant to the DGCL, the corporation’s bylaws may be amended by the stockholders. If the corporation confers the power to amend bylaws upon its directors by including a provision to that effect in its certificate of incorporation, the board of directors may also amend the bylaws.	MLAC Shareholders may amend the MLAC Memorandum and Articles by special resolution. Prior to the consummation of a business combination, Article 178(a) of the MLAC Memorandum and Articles provides that only the holders of MLAC Class B Ordinary Shares shall carry the right to vote on any Special Resolution required to amend the constitutional documents of MLAC or to adopt new constitutional documents of MLAC, in each case, as a result of MLAC approving a transfer by way of continuation in a jurisdiction outside the Cayman Islands.
Limitation of Liability of Directors and Officers:	Pursuant to the DGCL a corporation may limit or eliminate a director’s and an officer’s personal liability for monetary damages to the corporation or its stockholders for breach of fiduciary duty as a director or as an officer, except for liability for: (i) any breach of the director’s or officer’s duty of loyalty to such corporation or its stockholders, (ii) acts or omissions by a director or an officer not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) a director’s willful or negligent violation of provisions of Delaware law governing payment of dividends and stock purchases or redemptions, (iv) any transaction from which the director or officer derived an improper personal benefit, or (v) an officer in any action by or in the right of the corporation.	Cayman Islands law does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against willful default, fraud or the consequences of committing a crime.

253

Provision	Pubco (Post-Closing)	MLAC
Indemnification of Directors and Officers:	Under the DGCL, a corporation is generally permitted to indemnify its directors and officers against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with a third-party action, suit or proceeding, or a derivative action, and against expenses actually and reasonably incurred in the defense or settlement of such action or suit (with certain restrictions applicable to indemnification of expenses in a derivative action), provided that there is a determination that the individual acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe the individual’s conduct was unlawful. Indemnification determinations for current directors and officers must be made by: (i) a majority of the disinterested directors, even though less than a quorum; (ii) a committee of such disinterested directors designated by a majority vote of such disinterested directors, even though less than a quorum; (iii) independent legal counsel in a written opinion if there are no such disinterested directors or if such directors so direct; or (iv) the stockholders. The DGCL requires indemnification of current or former directors and officers for expenses actually and reasonably incurred by such person relating to a successful defense on the merits or otherwise of a derivative or third-party action. Pursuant to the DGCL, a corporation may advance expenses relating to the defense of any action, suit or proceeding to directors, officers, employees, and agents contingent in certain circumstances upon those individuals entering into an undertaking to repay any advances if it is determined ultimately that those individuals are not entitled to be indemnified.	The MLAC Memorandum and Articles provide that every director and officer (which for the avoidance of doubt, shall not include auditors of MLAC), together with every former director and former officer (each an “Indemnified Person”) shall, to the maximum extent permitted by Cayman Islands law, be indemnified out of the assets of MLAC against any liability, action, proceeding, claim, demand, costs, damages or expenses, including legal expenses, whatsoever which they or any of them may incur as a result of any act or failure to act in carrying out their functions other than such liability (if any) that they may incur by reason of their own actual fraud, willful neglect or willful default. No Indemnified Person shall be liable to MLAC for any loss or damage incurred by MLAC as a result (whether direct or indirect) of the carrying out of their functions unless that liability arises through the actual fraud, willful neglect or willful default of such Indemnified Person. No person shall be found to have committed actual fraud, willful neglect or willful default unless or until a court of competent jurisdiction shall have made a finding to that effect.

SPAC Provisions:	Not applicable.	The MLAC Memorandum and Articles contain specific provisions which reflect its listing status as a SPAC. These include provisions related to, among other things, the following: MLAC Class B Ordinary Shares, redemption of Public Shares, business combination, business opportunities, termination if an initial business combination is not consummated by the end of the Combination Period and the Trust Account.
Anti-Takeover Provisions:	Pursuant to the DGCL, if a person or entity acquires 15% or more of the voting stock of a Delaware corporation (the “target”), then the interested stockholder may not engage in a business combination with the target for a period of three years, unless (a) the board approves the business combination and (b) the target stockholders approve the business combination by at least a 662∕3% vote (excluding the vote of any shares owned by the interested stockholder) at a stockholder meeting.	MLAC Memorandum and Articles provide that the board of directors is classified into three classes of directors. As a result, in most circumstances, a person can gain control of the MLAC Board only by successfully engaging in a proxy contest at three or more annual general meetings. MLAC’s authorized but unissued Class A ordinary shares and preference shares are available for future issuances without shareholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved Class A ordinary shares and preference shares could render more difficult or discourage an attempt to obtain control of MLAC by means of a proxy contest, tender offer, merger or otherwise.

255

Provision	Pubco (Post-Closing)	MLAC
Derivative Suits:	Pursuant to the DGCL, a stockholder bringing a derivative suit must have been a stockholder at the time of the wrong complained of or the stockholder must have received shares in the corporation by operation of law from a person who was such a stockholder at the time of the wrong complained of. In addition, the stockholder must remain a stockholder throughout the litigation. There is no requirement under the DGCL to advance the expenses of a lawsuit to a stockholder bringing a derivative suit.	Derivative actions have been brought in the Cayman Islands courts, and the Cayman Islands courts have confirmed the availability of such actions. In most cases, MLAC will be the proper plaintiff in any claim based on a breach of duty owed to MLAC, and a claim against (for example) MLAC officers or directors usually may not be brought by a shareholder. However, based both on Cayman Islands authorities and on English authorities, which would in all likelihood be of persuasive authority and be applied by a court in the Cayman Islands, exceptions to the foregoing principle apply in circumstances in which: • a company is acting, or proposing to act, illegally or beyond the scope of its authority; • the act complained of, although not beyond the scope of the authority, could be effected if duly authorized by more than the number of votes which have actually been obtained; or • those who control the company are perpetrating a “fraud on the minority.” A shareholder may have a direct right of action against MLAC where the individual rights of that shareholder have been infringed or are about to be infringed.
Dividend Rights:	Pursuant to the DGCL, the directors of a corporation may declare and pay dividends upon the shares of its capital stock either out of its surplus or, if there is no such surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year.	MLAC directors may resolve to pay dividends and other distributions on shares in issue and authorize payment of the dividends or other distributions out of the funds of MLAC lawfully available therefor. No dividend or other distribution shall be paid except out of the realized or unrealized profits of MLAC, out of the share premium account or as otherwise permitted by the law of the Cayman Islands.

Market price information regarding MLAC Class B Ordinary Shares is not provided here because there is no established public trading market for MLAC Class B Ordinary Shares.

There is currently no public market for the equity securities of the Company or Pubco. We are applying to list shares of Pubco Class A Stock on The Nasdaq Capital Market upon the Closing under the ticker symbol “AVAT”.

Dividends

MLAC, Pubco and the Company have not paid any cash dividends on their equity securities to date and do not intend to pay cash dividends prior to the completion of the Business Combination. The payment of cash dividends by Pubco in the future will be dependent upon the revenues and earnings, if any, and capital requirements and general financial condition of Pubco subsequent to the completion of the Business Combination. Following the completion of the Business Combination, the Pubco Board will consider whether or not to institute a dividend policy. It is presently intended that Pubco will retain its earnings for use in business operations and, accordingly, it is not anticipated that the Pubco Board will declare dividends in the foreseeable future. Further, if Pubco incurs further indebtedness, its ability to declare dividends may be limited by restrictive covenants Pubco may agree to in connection therewith.

257

DELIVERY OF DOCUMENTS TO SHAREHOLDERS

Pursuant to the rules of the SEC, MLAC and services that it employs to deliver communications to MLAC Shareholders are permitted to deliver to two or more shareholders sharing the same address a single copy of MLAC’s proxy statement to MLAC Shareholders. Upon written or oral request, MLAC will deliver a separate copy of its proxy statement to any MLAC Shareholder at a shared address to which a single copy of the document was delivered and who wishes to receive separate copies of such documents. MLAC Shareholders receiving multiple copies of such documents may request that MLAC deliver single copies of such documents in the future. MLAC Shareholders may notify MLAC of their requests by calling or writing MLAC at its principal executive offices at Mountain Lake Acquisition Corp., 903 Tahoe Blvd STE 802, PMB 45, Incline Village NV, 89451. Following the Business Combination, such requests should be made by calling or writing to Pubco at 11 W. 42^nd Street, 2^nd Floor, New York, NY 10036, and its telephone number is 332-240-1155.

261

HOUSEHOLDING INFORMATION

Unless MLAC has received contrary instructions, MLAC may send a single copy of this proxy statement/ prospectus to any household at which two or more MLAC Shareholders reside if MLAC believes the MLAC Shareholders are members of the same family. This process, known as “householding,” reduces the volume of duplicate information received at any one household and helps to reduce MLAC’s expenses. However, if MLAC Shareholders prefer to receive multiple sets of MLAC’s disclosure documents at the same address this year or in future years, the MLAC Shareholders should follow the instructions described below. Similarly, if an address is shared with another MLAC Shareholder and together both of the MLAC Shareholders would like to receive only a single set of MLAC’s disclosure documents, the MLAC Shareholders should follow these instructions:

If the MLAC Ordinary Shares are registered in the name of the MLAC Shareholder, the MLAC Shareholder should contact MLAC’s offices at Mountain Lake Acquisition Corp., 930 Tahoe Blvd STE 802 PMB 45, Incline Village, NV 89451. If a bank, broker or other nominee holds the shares, the MLAC Shareholder should contact the bank, broker or other nominee directly.

262

SOLICITATION OF PROXIES

MLAC will bear the expenses incurred in connection with the printing and mailing of this proxy statement/prospectus. To assist in the solicitation of proxies, MLAC has hired Sodali & Co as its proxy solicitor, for a fee of $22,500, plus reimbursement of out-of-pocket expenses for their services. MLAC and its proxy solicitor may also request banks, brokers, trustees and other intermediaries holding MLAC Ordinary Shares beneficially owned by others to send this proxy statement/prospectus to, and obtain proxies from, the beneficial owners and may reimburse such record holders for their reasonable out-of-pocket expenses in so doing. Solicitation of proxies by mail may be supplemented by telephone and other electronic means, advertisements and personal solicitation by the directors, officers or employees of MLAC. No additional compensation will be paid to MLAC’s directors, officers or employees for solicitation.

263

SHAREHOLDER PROPOSALS

If the Business Combination is consummated and Pubco holds a 2026 annual meeting of shareholders, it will provide notice of or otherwise publicly disclose the date on which the 2026 annual meeting of shareholders will be held. For any proposal to be considered for inclusion in Pubco’s proxy statement and form of proxy for submission to the shareholders at Pubco’s 2026 annual meeting of shareholders, assuming consummation of the Business Combination, it must be submitted in writing and comply with the requirements of Rule 14a-8 of the Exchange Act and the Amended and Restated Bylaws. Since the 2026 annual meeting would be Pubco’s first annual meeting of shareholders, such proposals must be received by Pubco at its offices at Avalanche Treasury Corporation, 11 W. 42^nd Street, 2^nd Floor, New York, NY 10036, a reasonable time before Pubco begins to print and mail the 2026 annual meeting proxy materials in order to be considered for inclusion in Pubco’s proxy materials for the 2026 annual meeting.

In addition, if the Business Combination is consummated, the Amended and Restated Bylaws provide notice procedures for shareholders to nominate a person as a director and to propose business to be considered by shareholders at a meeting. To be timely, a shareholder’s notice must be delivered to Avalanche Treasury Corporation, 11 W. 42^nd Street, 2^nd Floor, New York, NY 10036, not later than the close of business on the 90^th day nor earlier than the opening of business on the 120^th day before the anniversary date of the immediately preceding annual meeting of shareholders.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of

Mountain Lake Acquisition Corp.:

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Mountain Lake Acquisition Corp. (the “Company”) as of December 31, 2025 and 2024, and the related statements of operations, changes in shareholders’ deficit, and cash flows for the year ended December 31, 2025 and for the period from June 14, 2024 (inception) through December 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the year ended December 31, 2025 and for the period June 14, 2024 (inception) through December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, if the Company is unable to raise additional funds to alleviate liquidity needs and complete a business combination by June 16, 2026, then the Company will cease all operations except for the purpose of liquidating. The liquidity condition and date for mandatory liquidation and subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (the “PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

/s/ WithumSmith+Brown, PC

We have served as the Company’s auditor since 2024.

MOUNTAIN LAKE ACQUISITION CORP.

NOTES TO THE FINANCIAL STATEMENTS

NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Mountain Lake Acquisition Corp. (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on June 14, 2024. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses that the Company (“Business Combination”). The Company may pursue an acquisition opportunity in any industry or geographic location.

As of December 31, 2025, the Company has not commenced any operations. All activity for the period from June 14, 2024 (inception) through December 31, 2025, relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on December 12, 2024. On December 16, 2024, the Company consummated the Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the shares of Class A ordinary shares included in the Units sold, the “Public Shares”), which includes the partial exercise by the underwriters of their over-allotment option in the amount of 2,000,000 Units, at $10.00 per Unit, generating gross proceeds of $230,000,000, which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 805,000 private placement units (each, a “Private Placement Unit”) at a price of $10.00 per Private Placement Unit in a private placement to Mountain Lake Acquisition Sponsor LLC, a Delaware limited liability company (“Sponsor”), and BTIG, representative of the underwriters (“BTIG”), generating gross proceeds of $8,050,000, which is described in Note 4.

Transaction costs amounted to $13,354,261, consisting of $4,600,000 of cash underwriting fee, $8,050,000 of deferred underwriting fee and $704,261 of other offering costs. On October 1, 2025, the Company amended the Underwriting Agreement. As a result on the amendment, the Company reversed $7,050,000 deferred underwriting fee payable, resulting in a $1,000,000 outstanding balance on deferred underwriting fee payable reported on balance sheets.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering and the sale of Private Placement Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding any deferred underwriters fees and taxes payable on the income earned on the Trust Account) at the time the Company signs a definitive agreement in connection with the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act.

Upon the closing of the Proposed Public Offering, management has agreed that an amount equal to at least $10.05 per Unit sold in the Proposed Public Offering, including the proceeds of the Private Placement Units, will be held in a trust account (“Trust Account”) with Continental Stock Transfer & Trust Company acting as trustee and invested in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

MOUNTAIN LAKE ACQUISITION CORP.

NOTES TO THE FINANCIAL STATEMENTS

Following the closing of the Initial Public Offering on December 16, 2024, an amount of $231,150,000 ($10.05 per Unit) from the net proceeds of the sale of the Units, and a portion of the net proceeds from the sale of the Private Placement Units, was placed in the Trust Account with Continental Stock Transfer & Trust Company acting as trustee. The funds will be held in cash, including in demand deposit accounts at a bank, or invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company will provide its holders of the Public Shares (the “Public Shareholders”) with the opportunity to redeem, regardless of whether they abstain, vote for, or against, a Business Combination, all or a portion of their Public Shares upon either (i) the completion of the initial Business Combination or an earlier redemption in connection with the commencement of the consummation of the initial Business Combination if the Company determines it is desirable to facilitate the completion of the initial Business Combination, (ii) the redemption of the Public Shares if the Company is unable to complete the initial Business Combination within the Combination Period (as defined below), subject to applicable law, or (iii) the redemption of the Public Shares properly submitted in connection with a shareholder vote to amend the Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of the obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company has not consummated an initial Business Combination within the Combination Period or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity.

All of the Public Shares contain a redemption feature which allows for the redemption of such Public Shares in connection with the liquidation, if there is a shareholder vote or tender offer in connection with the initial Business Combination and in connection with certain amendments to the Amended and Restated Memorandum and Articles of Association (the “Amended and Restated Memorandum and Articles of Association”). The Public Shares were recorded at redemption value and classified as temporary equity at the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.”

Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks shareholder approval in connection with a Business Combination, the holders of the Founder Shares (as defined in Note 5) prior to the Initial Public Offering (the “Initial Shareholders”) have agreed to vote their Founder Shares and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the Initial Shareholders have agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination. In addition, the Company has agreed not to enter into a definitive agreement regarding an initial Business Combination without the prior consent of the Sponsor.

Notwithstanding the foregoing, the Company’s Amended and Restated Memorandum and Articles of Association provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company.

The Sponsor, executive officers, and directors have agreed, pursuant to a letter agreement, that they will not propose any amendment to the Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination within the Combination Period or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares.

If the Company is unable to complete a Business Combination within 18 months from the closing of the Initial Public Offering or during any extended time that the Company has to consummate a Business Combination beyond 18 months as a result of a shareholder vote to amend the Amended and Restated Memorandum and Articles of Association (the “Combination Period”), the

F-8

MOUNTAIN LAKE ACQUISITION CORP.

NOTES TO THE FINANCIAL STATEMENTS

Company will, but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any) subject to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. In such event, the rights will expire and be worthless.

In connection with the redemption of 100% of the Company’s outstanding Public Shares for a portion of the funds held in the Trust Account, each holder will receive a full pro rata portion of the amount then in the Trust Account, plus any pro rata interest earned on the fund held in the Trust Account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses).

The Initial Shareholders have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholders should acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company’s Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.05 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.05 per share due to reductions in the value of the trust assets, less taxes payable; provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have vendors, service providers (except the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Liquidity, Capital Resources and Going Concern

As of December 31, 2025, the Company had $452,680 in cash and a working capital surplus of $265,230. Further, the Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans.

In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standards Board (“FASB”) ASC Topic 205-40, “Presentation of Financial Statements-Going Concern”, as of December 31, 2025, the Company lacks the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the date of the issuance of the financial statements. The Company cannot ensure that its plans to raise capital or to consummate an initial Business Combination will be successful. In addition, Management has determined that if the Company is unable to complete an initial Business Combination within the Combination Period, then the Company will cease all operations except for the purpose of liquidating. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management plans to consummate an initial Business Combination prior to the mandatory liquidation date. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after June 16, 2026.

NOTES TO THE FINANCIAL STATEMENTS

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”).

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised it has different application dates for public or private companies. The Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of the financial statement in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statement, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had $452,680 and $1,383,392 in cash and no cash equivalents as of December 31, 2025 and 2024, respectively.

Cash and Marketable Securities Held in Trust Account

As of December 31, 2025 and 2024, the assets held in the Trust Account, amounted to $241,230,572 and $231,643,853, respectively. The Company classifies its U.S. Treasury and equivalent securities as held to maturity in accordance with ASC Topic

F-10

MOUNTAIN LAKE ACQUISITION CORP.

NOTES TO THE FINANCIAL STATEMENTS

320, “Investments - Debt and Equity Securities.” Held-to-maturity securities are those securities which the Company has the ability and intent to hold until maturity. Held-to-maturity treasury securities are recorded at amortized cost on the accompanying balance sheets and adjusted for the amortization or accretion of premiums or discounts. When the Company’s investments held in the Trust Account are comprised of money market securities, the investments are classified as trading securities. Gains and losses resulting from the change in fair value of these securities are included in interest earned on marketable securities held in the Trust Account in the accompanying statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

Class A Ordinary Shares Subject to Possible Redemption

The Public Shares contain a redemption feature which allows for the redemption of such Public Shares in connection with the Company’s liquidation, or if there is a shareholder vote or tender offer in connection with the Company’s initial Business Combination. In accordance with ASC 480-10-S99, the Company classifies Public Shares subject to redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, as of December 31, 2025 and 2024, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of the Company’s balance sheets.

As of December 31, 2025 and 2024, the Class A ordinary shares subject to possible redemption reflected in the balance sheets are reconciled in the following table:

Gross proceeds	$	230,000,000
Less:
Proceeds allocated to Public Share Rights		(2,070,000)
Class A ordinary shares issuance costs		(13,210,471)
Plus:

Plus:
Accretion for Class A ordinary shares to redemption amount		9,586,719
Class A ordinary shares subject to possible redemption, December 31, 2025	$	241,230,572

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheets, primarily due to their short-term nature.

Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

• Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets;

F-11

MOUNTAIN LAKE ACQUISITION CORP.

NOTES TO THE FINANCIAL STATEMENTS

• Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Offering Costs

The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and rights, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the rights and then to the Class A ordinary shares. Offering costs allocated to Public Shares were charged to temporary equity, and offering costs allocated to share rights included in the Public and Private Placement Units were charged to shareholders’ equity (deficit) as the rights, after management’s evaluation, were accounted for under equity treatment.

Income Taxes

The Company complies with the accounting and reporting requirements of ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2025 and 2024, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

There is currently no taxation imposed on income by the government of the Cayman Islands. In accordance with Cayman Islands federal income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Net Income per Ordinary Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of ordinary shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of ordinary shares. This presentation assumes a business combination as the most likely outcome. Net income per ordinary share is calculated by dividing the net income by the weighted average ordinary shares outstanding for the respective period.

The calculation of diluted net income per ordinary share does not consider the effect of the rights issued in connection with the Initial Public Offering and the Private Placement to purchase an aggregate of 7,666,667 Class A ordinary shares in the calculation of diluted income per ordinary share, because their exercise is contingent upon future events. As a result, diluted net income per ordinary share is the same as basic net income per ordinary share for the year ended December 31, 2025 and for the period from June 14, 2024

F-12

(inception) through December 31, 2024. Accretion associated with the redeemable Class A ordinary shares is excluded from earnings per ordinary share as the redemption value approximates fair value.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.

Share Rights

The Company accounts for the Public and Private Placement Rights issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the rights under equity treatment at their assigned values.

Recently Issued Accounting Standards

Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

NOTE 3 — INITIAL PUBLIC OFFERING

Pursuant to the Initial Public Offering, on December 16, 2024, the Company sold 23,000,000 Units, which includes the partial exercise by the underwriters of their over-allotment option in the amount of 2,000,000 Units, at a price of $10.00 per Unit. Each Unit consists of one Class A ordinary share and one right. Each right entitles the holder thereof to receive one-tenth of one Class A ordinary share upon the consummation of an initial Business Combination.

NOTE 4 — PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Sponsor and BTIG purchased an aggregate of 805,000 Private Placement Units (495,000 Private Placement Units purchased by the Sponsor and 310,000 Private Placement Units purchased by BTIG), at a price of $10.00 per Private Placement Units from the Company in a private placement, generating gross proceeds of $8,050,000. A portion of the proceeds from the sale of the Private Placement Units was added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Units held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law). The Private Placement Units are identical to the units sold in the Initial Public Offering.

NOTE 5 — RELATED PARTY TRANSACTIONS

Founder Shares

On June 27, 2024, the Sponsor made a capital contribution of $25,000 to cover certain expenses on behalf of the Company in exchange for issuance of 7,187,500 Class B ordinary shares (the “Founder Shares”). Subsequently, on December 12, 2024, the Company, through a share capitalization, issued an additional 359,375 Founder Shares to the Sponsor, resulting in an aggregate of 7,546,875 Founder Shares issued and outstanding. The holders of the Founder Shares agreed to forfeit and cancel up to an aggregate of 984,375 Founder Shares, on a pro rata basis, to the extent that the option to purchase additional Units is not exercised in full by the underwriters. The forfeiture will be adjusted to the extent that the option to purchase additional Units is not exercised in full by the underwriters so that the Founder Shares will represent approximately 23.2% of all of the Company’s issued and outstanding shares after the Initial Public Offering. On December 16, 2024, the underwriters partially exercised their over-allotment option as part of the closing of the Initial Public Offering and forfeited their option to exercise the remaining over-allotment option. As such, 359,375 Founder Shares were forfeited.

With certain limited exceptions, the Founder Shares are not transferable, assignable or salable (except to the Company’s officers and directors and other persons or entities affiliated with the Sponsor, each of whom will be subject to the same transfer restrictions) until the earlier to occur of (i) one year after the completion of the initial Business Combination or (ii) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction after the initial Business Combination that results in all of the shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property; except to certain permitted transferees and under certain circumstances as described herein. Any permitted transferees will be subject to the same restrictions and other agreements of the Initial Shareholders with respect to any Founder Shares. Notwithstanding the foregoing, if (1) the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination or (2) if the Company consummates a transaction after the initial Business Combination which results in the shareholders having the right to exchange their shares for cash, securities or other property, the Founder Shares will be released from the lock-up.

Due to Sponsor

As of December 31, 2025 and 2024, the Company owed the Sponsor $688 and $3,183 in connection with the overfunding of the private placement, respectively, offset by the payments made on behalf of the Sponsor.

Related Party Loans

On June 27, 2024, the Sponsor agreed to loan the Company up to $200,000 (as amended to $300,000 on September 23, 2024) pursuant to a promissory note (the “Note”). The Note is non-interest bearing, unsecured and due on the earlier of December 31, 2024, the closing of the Proposed Public Offering, or the date the Company determines not to proceed with the Proposed Public Offering. On December 31, 2024, the Company repaid the total outstanding balance of the note amounting to $275,193. Borrowings under the note are no longer available.

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor, members of the Company’s founding team or any of their affiliates may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be converted into units of the post-Business Combination entity at a price of $10.00 per Unit. The units would be identical to the Private Placement Units. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of December 31, 2025 and 2024, the Company had no borrowings under the Working Capital Loans.

Services Agreement

The Company agreed, commencing on the closing of Initial Public Offering through the earlier of consummation of the initial Business Combination and the liquidation, to pay the Chairman and Chief Executive Officer and the President and Chief Financial Officer, a total of up to $20,000 per month for their services as executive officers and directors of the Company. For the year ended December 31, 2025, the Company incurred and paid an expense of $240,000 of fees for these services. For the period from June 14, 2024 (inception) through December 31, 2024, no fees were incurred for these services.

NOTE 6 — COMMITMENTS AND CONTINGENCIES

Registration and Shareholder Rights

The holders of the Founder Shares, Private Placement Units (and underlying securities) and any Units (and underlying securities) that may be issued on conversion of Working Capital Loans are entitled to registration rights pursuant to a registration rights agreement requiring the Company to register such securities for resale. The holders of these securities will be entitled to make up to three demands, excluding short form registration demands, that the Company register such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that the Company will not be required to effect or permit any registration or cause any registration statement to become effective until termination of the applicable lock-up period. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The underwriters had a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,150,000 units to cover over-allotments, if any. On December 16, 2024, simultaneously with the closing of the Initial Public Offering, the underwriters elected to partially exercise the over-allotment option to purchase an additional 2,000,000 Units at a price of $10.00 per Unit and forfeited their right to exercise the remaining over-allotment option.

The underwriters were paid a cash underwriting discount of $0.20 per Unit, or $4,600,000 in the aggregate. In addition, the underwriters are entitled to a deferred underwriting fee of $0.35 per Unit, or $8,050,000 in the aggregate. The deferred fee will

NOTES TO THE FINANCIAL STATEMENTS

become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

On October 1, 2025, the Company and representative of the underwriters thereunder (the “Representative”) amended the Underwriting Agreement, effective and conditioned upon consummation of the Business Combination, by deleting Section 1.3 of the Underwriting Agreement and replacing it with the following: “1.3 Deferred Underwriting Commission. The Representative agrees that an aggregate amount equal to one million dollars ($1,000,000) (the “Deferred Underwriting Commission”), will be deposited and held in the Trust Account and payable in cash directly from the Trust Account, without accrued interest, to the Representative for its own account upon consummation of the Company’s initial merger, share exchange, asset acquisition, share purchase, reorganization, or similar business combination with one or more businesses (the “Business Combination”). In the event that the Company is unable to consummate a Business Combination and Continental, as the trustee of the Trust Account (in this context, the “Trustee”), commences liquidation of the Trust Account as provided in the Trust Agreement, the Representative agrees that: (i) the Representative shall forfeit any rights or claims to the Deferred Underwriting Commission, including any accrued interest thereon; and (ii) the Deferred Underwriting Commission, together with all other amounts on deposit in the Trust Account, shall be distributed on a pro-rata basis among the Public Shareholders. Any Deferred Underwriting Commissions shall be deemed fully earned by each Underwriter upon the payment of the purchase price for the Units purchased by such underwriter on the closing of the Offering (including payment of the purchase price of any Option Units) and will be paid only if and when the Company consummates its Business Combination.” The Company and the Representative agree that any reference in the Underwriting Agreement to the amount owed for the Deferred Underwriting Commission that is inconsistent with the provisions of Section 1.3, as amended by this Paragraph 1, shall be deemed amended to be consistent with the provisions of Section 1.3, as amended by this Paragraph 1.

The amendment of the Underwriting Agreement shall apply only in connection with the Business Combination and shall not apply in connection with any Business Combination that may be contemplated or consummated between the Company and any party other than Avalanche Treasury Company, LLC or its affiliates. The parties agree that if the Business Combination is terminated for any reason, this Letter Agreement shall be void and of no effect for all purposes. As a result on the amendment above, the Company reversed $7,050,000 deferred underwriting fee payable, resulting to $1,000,000 outstanding balance on deferred underwriting fee payable reported on balance sheets.

Risks and Uncertainties

The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine conflict and the recent escalation of the Israel-Hamas conflict. In response to the ongoing Russia-Ukraine conflict, the North Atlantic Treaty Organization (“NATO”) deployed additional military forces to eastern Europe, and the United States, the United Kingdom, the European Union and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The invasion of Ukraine by Russia and the escalation of the Israel-Hamas conflict and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyberattacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets.

On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted into law in the United States. The significant provisions of OBBBA include the permanent extension and modification of certain provisions of the Tax Cuts and Jobs Act which was enacted in 2017, including international tax provisions and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented in later years. The Company is evaluating the provisions of OBBBA, but it is not expected to have a material impact on the Company’s financial statements.

NOTES TO THE FINANCIAL STATEMENTS

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the Russian invasion of Ukraine, the escalation of the Israel-Hamas conflict, enactment of OBBBA and subsequent sanctions or related actions, could adversely affect the Company’s search for an initial Business Combination and any target business with which the Company may ultimately consummate an initial Business Combination.

Business Combination Agreement

On October 1, 2025, the Company entered into a Business Combination Agreement (the “Business Combination Agreement”) with Avalanche Treasury Corporation, a Delaware corporation (“Pubco”), Avalanche SPAC Merger Sub LLC, a Delaware limited liability company, Avalanche Company Merger Sub LLC, a Delaware limited liability company, Avalanche Treasury Company LLC, a Delaware limited liability company (the “AT Company”), and Dragonfly Digital Management, LLC, a Delaware limited liability company (the “Seller”). The transactions contemplated by the Business Combination Agreement are referred to as the “Proposed Business Combination.” Concurrently with the execution of the Business Combination Agreement, the Company entered into a Sponsor Support Agreement with the Sponsor and Pubco (the “Sponsor Support Agreement”). In addition, the Sponsor agreed pursuant to the Sponsor Support Agreement to effect certain security cancellations and to deposit certain Pubco Class A Stock issued to it at the closing of the Proposed Business Combination (the “Closing”) into escrow in connection with the Closing.

Concurrently with the execution of the Business Combination Agreement, Pubco, the AT Company and the Company entered into subscription agreements (collectively, the “Company Unit Subscription Agreements”) with certain investors (the “Company Unit Investors”), pursuant to which the Company Unit Investors agreed to purchase, payable in cash or USD Coin (“USDC”), unlocked AVAX or locked AVAX, and the AT Company agreed to issue and sell, approximately $274 million worth of Company Class A units (the “Subscribed Units”) at a price of $10.00 per Subscribed Unit, in a private placement (the “Company Unit Subscription”), upon the terms and subject to the conditions set forth therein. At the Closing, each Subscribed Unit held by Company Unit Investors will be converted automatically into one share of Pubco Class A Stock. Pursuant to the Company Unit Subscription Agreement, Pubco agreed to use commercially reasonable efforts to cause the Pubco Class A Stock into which the Subscribed Units will be converted upon Closing to be registered with the SEC.

Concurrently with the execution of the Business Combination Agreement and the TSA (as defined below), the Seller, the AT Company, Pubco, Avalanche BVI and Avalanche Cayman (together with Avalanche BVI, the “Foundation”), entered into an asset sale and contribution agreement (the “Contribution Agreement”), pursuant to which, on the date of the Business Combination Agreement: (a) the Foundation agreed to sell a minimum of $200 million of AVAX tokens on a pre-discount basis to the AT Company on the terms and subject to the conditions set forth in a Token Sale Agreement (the “TSA”) by and between the Company and the Foundation, and (b) the Seller agreed to contribute, directly and indirectly through certain related funds, 1,960,040 AVAX tokens to the AT Company in exchange for 5,805,638 Company units.
