Our stockholders will also be asked to consider and vote on other proposals relating to the Business Combination, each of which is more fully described herein.

321 North Clark Street, Suite 2440
Chicago, IL 60654

Dear XPDB Stockholder:

On June 5, 2023, Power & Digital Infrastructure Acquisition II Corp., a Delaware corporation (“XPDB”), and XPDB Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of XPDB (“Merger Sub”), entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time in accordance with its terms, the “Merger Agreement”) with Montana Technologies LLC, a Delaware limited liability company (“Montana”), pursuant to which, and subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into Montana (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Business Combination”), with Montana surviving the Merger as a wholly owned subsidiary of XPDB. Consummation of the Business Combination is subject to the adoption of the Merger Agreement and approval of the Business Combination by XPDB’s stockholders.

As part of the Business Combination, Montana Equityholders (as defined in the accompanying proxy statement/prospectus) will receive aggregate consideration of approximately $421.9 million (the “Purchase Price”), which amount will be (i) adjusted down at the closing of the Business Combination (the “Closing”) by the Dilution Factor (as defined in the accompanying proxy statement/prospectus), if positive only, and (ii) adjusted up at Closing by the implied value of any equity interests (or securities convertible, exchangeable or exercisable therefor) issued by Montana in the Capital Raise (as defined in the accompanying proxy statement/prospectus) assuming a $10.00 per share value (the Purchase Price, as so adjusted, the “Merger Consideration”). The “Dilution Factor” is equal to (i) the implied value of the equity interests (or securities convertible, exchangeable or exercisable therefor) issued by Montana in the Capital Raise assuming a $10.00 per share value minus (ii) the amount of the gross cash proceeds actually received by Montana from the Capital Raise. After giving effect to the conversion of all outstanding Montana Preferred Units (as defined in the accompanying proxy statement/prospectus) into Montana Class B Common Units (as defined in the accompanying proxy statement/prospectus), which will occur prior to the effective time of the Merger, the Merger Consideration will be payable (i) in the case of holders of Montana Class B Common Units and Montana Class C Common Units (each as defined in the accompanying proxy statement/prospectus), in the form of newly issued shares of Class A common stock, par value $0.0001 per share, of the Post-Combination Company (as defined in the accompanying proxy statement/prospectus) (the “Class A Common Stock”), with a $10.00 value ascribed to each such share and which will entitle the holder thereof to one vote per share on all matters submitted to a vote of the holders of Class A Common Stock, whether voting separately as a class or otherwise, (ii) in the case of holders of Montana Class A Common Units (as defined in the accompanying proxy statement/prospectus), in the form of newly issued shares of Class B common stock, par value $0.0001 per share, of the Post-Combination Company (the “Class B Common Stock”), with a $10.00 value ascribed to each such share and which will entitle the holder thereof to a number of votes per share such that the Montana Equityholders as of immediately prior to the Closing will, immediately following the Closing, collectively own shares representing at least 80% of the voting power of all classes of capital stock of the Post-Combination Company entitled to vote on matters submitted to a vote of the stockholders of the Post-Combination Company, and (iii) in the case of holders of Montana Options and Montana Warrants (each as defined in the accompanying proxy statement/prospectus), in the form of options and warrants of the Post-Combination Company, respectively, having substantially similar terms to the corresponding Montana Options and Montana Warrants, in each case as described in the accompanying proxy statement/prospectus.

Montana Equityholders (other than holders of Montana Warrants) (the “Eligible Equityholders”) will also have the opportunity to receive additional equity consideration (in each case, in accordance with their respective pro rata share) in the form of shares of Class A Common Stock, with a $10.00 value ascribed to each share (the “Earnout Shares”), only upon full completion of construction and operational viability (including all permitting, regulatory approvals and necessary or useful inspections) of new production capacity of Montana’s key components or assemblies based solely on demand from bona fide customer commitments evidenced by binding contracts (or in the discretion of a majority of the independent members of the board of directors of the Post-Combination Company (the “Post-Combination Company Board”), a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known price or pricing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA (as defined in the accompanying proxy statement/prospectus) of more than $150,000,000 (the “Threshold Annualized EBITDA”), which shall be determined by a majority of the independent members of the Post-Combination Company Board in its sole discretion, equal to (i) the ratio of (x) (1) the Annualized EBITDA that is

expected from such new production capacity (the “Expected Annualized EBITDA”) less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000.

The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing. A majority of the independent members of the Post-Combination Company Board then serving will have sole discretion in determining, among other things, the achievement of the applicable milestones, the calculations of payments of Earnout Shares to the applicable Montana Equityholders, the dates on which construction and operational viability of new production capacity is deemed completed and whether to consent to a transfer of the applicable Montana Equityholder’s right to receive Earnout Shares. Earnout Shares issuable in respect of Montana Options outstanding as of immediately prior to the effective time of the Merger may be issued to the holder of such Montana Option only if such holder continues to provide services (whether as an employee, direct or individual independent contractor) to the Post-Combination Company or one of its subsidiaries through the date on which such Earnout Shares are issued, as determined by a majority of the independent members of the Post-Combination Company Board.

Upon consummation of the Business Combination, certain shares of Class A Common Stock owned by the Sponsor (as defined in the accompanying proxy statement/prospectus) following the conversion of the Founder Shares (as defined in the accompanying proxy statement/prospectus) will be subject to (i) certain lock-up restrictions and (ii) certain time and performance-based vesting provisions, as described in the accompanying proxy statement/prospectus.

Prior to Closing, Montana will use its commercially reasonable efforts to enter into subscription agreements (each, a “Subscription Agreement” and collectively, the “Subscription Agreements”) with certain investors (the “Subscribers”) pursuant to which Montana will agree to issue equity interests (or securities convertible, exchangeable or exercisable therefor) in Montana (the “Capital Raise”), in exchange for an agreed upon purchase price.

Based on the number of Montana Common Units and Montana Preferred Units outstanding and the number of Montana Common Units issuable upon the net exercise of Montana Options and Montana Warrants (each as defined in the accompanying proxy statement/prospectus) as of , 2023 (the “Record Date”), and assuming that Montana does not issue any equity interests (or securities convertible, exchangeable or exercisable therefor) in the Capital Raise prior to Closing, (i) the estimated number of shares of Class A Common Stock issuable for each Montana Common Unit is approximately , (ii) the total number of shares of Class A Common Stock expected to be issued to Montana Equityholders in connection with the Closing is approximately million (approximately million on a fully diluted basis under certain assumptions described in the accompanying proxy statement/prospectus), and (iii) the total number of shares of Class B Common Stock expected to be issued to certain Montana Equityholders in connection with the Closing is approximately . Based on the assumption that no shares of XPDB Class A Common Stock are validly redeemed and the other assumptions described in the accompanying proxy statement/prospectus, (i) holders of XPDB Class A Common Stock and XPDB Class B Common Stock (each as defined in the accompanying proxy statement/prospectus) will hold (x) approximately % and % of the total outstanding common stock of the Post-Combination Company, respectively, and (y) approximately % and % of the voting power of the Post-Combination Company, respectively, (ii) holders of Montana Common Units as of immediately prior to the Closing will hold, in the aggregate, approximately % of the Class A Common Stock and 100% of the Class B Common Stock immediately following the Closing, representing % and % of the total outstanding common stock and voting power of the Post-Combination Company, respectively, and (iii) Montana Equityholders (including holders of outstanding Montana Options and Montana Warrants) will hold, in the aggregate and on a fully diluted basis, approximately % of the Class A Common Stock and 100% of the Class B Common Stock. Based on the Assuming Maximum Contractual Redemptions Scenario (as defined in the accompanying proxy statement/prospectus) and the other assumptions described in the accompanying proxy statement/prospectus, (i) holders of XPDB Class A Common Stock and XPDB Class B Common Stock will hold (x) approximately % and % of the total outstanding common stock of the Post-Combination Company, respectively, and (y) approximately % and % of the voting power of the Post-Combination Company, respectively, (ii) holders of Montana Common Units as of immediately prior to the Closing will hold, in the aggregate, approximately % of the Class A Common Stock and 100% of the Class B Common Stock immediately following the Closing, representing % of the voting power of the Post-Combination Company, and (iii) Montana Equityholders (including holders of outstanding Montana Options and Montana Warrants) will hold, in the aggregate and on a fully diluted basis, approximately % of the Class A Common Stock and 100% of the Class B Common Stock.

and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Business Combination Proposal, the Charter Proposal, the Director Election Proposal, the Nasdaq Proposal, the Incentive Plan Proposal or the Employee Stock Purchase Plan Proposal.

These items of business are described in the accompanying proxy statement/prospectus, which we encourage you to read in its entirety before voting. Only holders of record of XPDB Class A Common Stock and XPDB Class B Common Stock (collectively, “XPDB Common Stock”) at the close of business on , 2023 (the “Record Date”) are entitled to notice of the Special Meeting and to vote and have their votes counted at the Special Meeting and any adjournments or postponements of the Special Meeting.

Pursuant to XPDB’s Amended and Restated Certificate of Incorporation (the “Existing Charter”), XPDB will provide holders of XPDB Class A Common Stock included as part of the units sold in the XPDB IPO (as defined in the accompanying proxy statement/prospectus) (such shares, the “Public Shares”) with the opportunity to redeem their Public Shares for cash equal to their pro rata share of the aggregate amount on deposit in the trust account established in connection with the XPDB IPO (the “Trust Account”), as of two business days prior to the consummation of the Business Combination (including interest earned on the funds held in the Trust Account and not previously released to XPDB to pay its taxes). For illustrative purposes, based on funds in the Trust Account of approximately $110 million on June 30, 2023, the estimated per Public Share redemption price would have been approximately $10.37, excluding additional interest earned on the funds held in the Trust Account and not previously released to XPDB to pay taxes. Holders of Public Shares (the “XPDB Public Stockholders”) may elect to redeem their shares even if they vote for the Business Combination Proposal. An XPDB Public Stockholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended), will be restricted from seeking redemption rights with respect to more than 15% of the Public Shares without the consent of XPDB. Accordingly, all Public Shares in excess of 15% held by an XPDB Public Stockholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group,” will not be redeemed for cash without the consent of XPDB. XPDI Sponsor II LLC, a Delaware limited liability company (the “Sponsor”), and XPDB’s directors and officers have agreed to waive their redemption rights in connection with the consummation of the Business Combination with respect to any shares of XPDB Common Stock they may hold (which waiver was provided in connection with the XPDB IPO and without any separate consideration paid in connection with providing such waiver). As of the Record Date, the Initial Stockholders (as defined in the accompanying proxy statement/prospectus) own approximately % of all outstanding XPDB Common Stock, consisting of the Founder Shares (as defined in the accompanying proxy statement/prospectus).

Q: WHY AM I RECEIVING THIS DOCUMENT?

A: XPDB is sending this proxy statement/prospectus to its stockholders to help them decide how to vote their shares of XPDB Common Stock with respect to the matters to be considered at the Special Meeting.

Information about the Special Meeting, the Business Combination and the other business to be considered by stockholders at the Special Meeting is contained in this proxy statement/prospectus.

Table of Contents

Common Stock (rounded down to the nearest whole share) equal to the product of (x) the number of Montana Common Units underlying such option immediately prior to the Closing and (y) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per Montana Common Unit underlying such option immediately prior to the Closing divided by (B) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, and (iv) in the case of holders of Montana Warrants, each outstanding Montana Warrant will be converted into a warrant to purchase, upon the same terms and conditions as are in effect with respect to the corresponding Montana Warrant immediately prior to the Closing, including with respect to vesting and termination-related provisions, a number of shares of Class A Common Stock equal to the product of (x) the number of Montana Common Units underlying such warrant immediately prior to the Closing and (y) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, at an exercise price per share equal to (A) the exercise price per Montana Common Unit underlying such warrant immediately prior to the Closing divided by (B) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement. Montana Equityholders (other than holders of Montana Warrants) (the “Eligible Equityholders”) will also have the opportunity to receive additional equity consideration (in each case, in accordance with their respective pro rata share) in the form of shares of Class A Common Stock with a $10.00 value ascribed to each share (the “Earnout Shares”) only upon full completion of construction and operational viability (including all permitting, regulatory approvals and necessary or useful inspections) of new production capacity of Montana’s key components or assemblies based solely on demand from bona fide customer commitments evidenced by binding contracts (or in the sole discretion of a majority of the independent members of the Post-Combination Company Board, a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known price or pricing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA of more than $150,000,000 (the “Threshold Annualized EBITDA”), which shall be determined by a majority of the independent members of the Post-Combination Company Board in their sole discretion, equal to (i) the ratio of (x) (1) the Annualized EBITDA that is expected from such new production capacity (the “Expected Annualized EBITDA”) less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000.

The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing. A majority of the independent members of the Post-Combination Company Board then serving will have sole discretion in determining, among other things, the achievement of the applicable milestones, the calculations of payments of Earnout Shares to the applicable Montana Equityholders, the dates on which construction and operational viability of new production capacity is deemed completed and whether to consent to a transfer of the applicable Montana Equityholder’s right to receive Earnout Shares. Earnout Shares issuable in respect of Montana Options outstanding as of immediately prior to the effective time of the Merger may be issued to the holder of such Montana Option only if such holder continues to provide services (whether as an employee, director or individual independent contractor) to the Post-Combination Company or one of its subsidiaries through the date on which such Earnout Shares are issued, as determined by a majority of the independent members of Post-Combination Company Board. See the section entitled “The Merger Agreement — Earnout Shares.”

Prior to Closing, Montana will use its commercially reasonable efforts to enter into Subscription Agreements with the Subscribers pursuant to the Capital Raise, in exchange for an agreed upon purchase price.

Based on the number of Montana Common Units and Montana Preferred Units outstanding as of the Record Date and the number of Montana Common Units issuable upon the net exercise of Montana Options and Montana Warrants as of the Record Date, and assuming that Montana does not issue any equity interests (or securities convertible therefor) in the Capital Raise prior to Closing, (i) the estimated number of shares of Class A Common Stock issuable for each Montana Common Unit is approximately , (ii) the total number of shares of Class A Common Stock expected to be issued to Montana Equityholders in connection with the Closing is approximately million (approximately million on a fully diluted basis under certain assumptions described in this proxy statement/prospectus), and (iii) the total number of shares of

Table of Contents

Class B Common Stock expected to be issued to certain Montana Equityholders in connection with the Closing is approximately million. Based on the assumption that no shares of XPDB Class A Common Stock are validly redeemed and the other assumptions described in this proxy statement/prospectus, (i) holders of XPDB Class A Common Stock and XPDB Class B Common Stock will hold (x) approximately % and % of the total outstanding common stock of the Post-Combination Company, respectively and (y) approximately % and % of the voting power of the Post-Combination Company, respectively, (ii) holders of Montana Common Units as of immediately prior to the Closing will hold, in the aggregate, approximately % of the Class A Common Stock and 100% of the Class B Common Stock immediately following the Closing, representing % and % of the total outstanding common stock and voting power of the Post-Combination Company, respectively, and (iii) Montana Equityholders (including holders of outstanding Montana Options and Montana Warrants) will hold, in the aggregate and on a fully diluted basis, approximately % of the Class A Common Stock and 100% of the Class B Common Stock. Based on the Assuming Maximum Contractual Redemptions Scenario and the other assumptions described in this proxy statement/prospectus, (i) holders of XPDB Class A Common Stock and XPDB Class B Common Stock will hold (x) approximately % and % of the total outstanding common stock of the Post-Combination Company, respectively and (y) approximately % and % of the voting power of the Post-Combination Company, respectively, (ii) holders of Montana Common Units as of immediately prior to the Closing will hold, in the aggregate, approximately % of the Class A Common Stock and 100% of the Class B Common Stock immediately following the Closing, representing % of the voting power of the Post-Combination Company, and (iii) Montana Equityholders (including holders of outstanding Montana Options and Montana Warrants) will hold, in the aggregate and on a fully diluted basis, approximately % of the Class A Common Stock and 100% of the Class B Common Stock.

Q: WHAT IS THE CAPITAL RAISE?

A: Prior to Closing, Montana will use its commercially reasonable efforts to enter into Subscription Agreements with certain Subscribers, pursuant to which Montana will agree to issue equity interests (or securities convertible, exchangeable and exercisable therefor) in Montana in exchange for an agreed upon purchase price. The Capital Raise is expected to be conditioned on customary closing conditions.

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 Special Meeting, which is set for , 2023; however, such meeting could be adjourned, as described herein. Neither XPDB nor Montana can assure you of when or if the Business Combination will be completed and it is possible that factors outside of the control of both companies could result in the Business Combination being completed at a different time or not at all. XPDB must first obtain the approval of its stockholders for certain of the Proposals set forth in this proxy statement/prospectus for their approval and XPDB and Montana must also first satisfy certain closing conditions. See the section entitled “The Merger Agreement — Conditions to Closing of Business Combination.”

Q: WHAT HAPPENS IF THE BUSINESS COMBINATION IS NOT COMPLETED?

A: If the Business Combination is not completed, Montana Equityholders will not receive any consideration for their Montana securities. Instead, Montana will remain an independent company. See the section entitled “The Merger Agreement — Termination” and “Risk Factors.”

Additionally, if XPDB does not complete the Business Combination with Montana for whatever reason, XPDB would search for another target business with which to complete a business combination. If XPDB does not complete the Business Combination with Montana or another target business by December 14, 2023 or such further extended date as determined by the XPDB Board in accordance with the Existing Charter (the “Completion Window”), XPDB must redeem 100% of the outstanding Public Shares, at a per-share price, payable in cash, equal to the amount then held in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to XPDB to pay taxes (less up to $100,000 of interest to pay dissolution expenses) divided by the number of outstanding Public Shares. The Initial Stockholders have no redemption rights in the event a business combination is not effected by the end of the Completion Window, and, accordingly, their Founder Shares will be worthless. Additionally, in the event of such liquidation, there will be no distribution with respect to XPDB’s outstanding warrants. Accordingly, the warrants will expire worthless.

Q: HOW WILL THE POST-COMBINATION COMPANY BE MANAGED AND GOVERNED FOLLOWING THE BUSINESS COMBINATION?

A: Concurrently with the consummation of the Business Combination, XPDB’s officers and directors, other than Patrick C. Eilers, will resign from their respective positions. Following the Closing, the Post-Combination Company’s executive officers are expected to be the current management team of Montana. See the section entitled “Management of the Post-Combination Company Following the Business Combination” for more information.

XPDB is, and after the Closing, the Post-Combination Company will continue to be, managed by a board of directors. Following the Closing, the size of the board of directors will be directors and will consist of , , , and Patrick C. Eilers.

Following the Closing, we expect that a majority of the directors will be independent under applicable Nasdaq listing rules. See the section entitled “Management of the Post-Combination Company Following the Business Combination” for more information.

Q: WHAT EQUITY STAKE WILL CURRENT XPDB STOCKHOLDERS, THE INITIAL STOCKHOLDERS AND THE MONTANA EQUITYHOLDERS HOLD IN THE POST-COMBINATION COMPANY FOLLOWING THE CLOSING?

A: Upon consummation of the Business Combination (assuming, among other things, that after the June Redemptions, no XPDB Public Stockholders exercise redemption rights in connection with the Closing and the other assumptions described under the section with the heading “Basis of Presentation and Glossary — Share Calculations and Ownership Percentages”), (i) the XPDB Public Stockholders are expected to own approximately 19.0% of the outstanding Post-Combination Company’s common stock, (ii) the Initial Stockholders are expected to own approximately 13.0% of the outstanding Post-Combination Company’s common stock, and (iii) the Montana Equityholders are expected to own approximately 68.0% of the Post-Combination Company’s common stock.

If any of the XPDB Public Stockholders exercise redemption rights in connection with the Closing, the percentage of the outstanding Post-Combination Company’s common stock held by the XPDB Public Stockholders will decrease, and the percentages of the outstanding Post-Combination Company’s common stock held by the Initial Stockholders and by the Montana Equityholders will increase, in each case, relative to the percentage held if none of the Public Shares are redeemed.

The following table illustrates varying ownership levels of the Post-Combination Company immediately following the Business Combination(1):

	Assuming Minimum Redemptions Scenario			Assuming Mid-Point Redemptions Scenario			Assuming Maximum Contractual Redemptions Scenario

Q: WHO IS MONTANA?

A: Montana is an atmospheric renewable energy and water harvesting technology company that aims to provide efficient and sustainable evaporative cooling and atmospheric water generation, reduce energy consumption, eliminate harmful refrigerants and create cost efficiencies through its AirJoule technology. AirJoule is a climate solution technology that harvests the untapped supply of renewable thermal energy in water vapor in the atmosphere in an effort to provide significant energy efficiency gains in HVAC, as well as a potential source of potable water. Montana is focused on developing and deploying AirJoule units worldwide as a key part of the solution to address global warming and water scarcity. As the demand for HVAC has increased, the demand for space cooling and water generation technology has also increased, and we believe Montana is poised to meet this demand with its AirJoule unit, which provides HVAC technology designed to be relatively energy efficient compared to traditional air conditioning systems. Additionally, we see companies coming under increasing pressure from governments, customers and the general public to transition to using clean and sustainable energy, and we believe Montana is in a position to bridge the gap between the increasing demands for both HVAC and renewable energy. Montana strives to alleviate the need for comfort cooling and water stress by providing its future clients with an efficient solution to HVAC and space cooling demands that harness renewable energy through AirJoule. See the section entitled “Information About Montana.”

Q: WHY IS XPDB PROPOSING THE BUSINESS COMBINATION?

A: XPDB was organized to effect a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

On December 14, 2021, XPDB completed its initial public offering of 28,750,000 units, with each unit consisting of XPDB Class A Common Stock and one-half of one XPDB public warrant (including 3,750,000 units issued pursuant to the full exercise of the underwriters’ over-allotment option), raising total gross proceeds of $287.5 million. On the same date, XPDB also completed a private placement of warrants to its Sponsor and the Anchor Investors (the “Private Placement”), raising total gross proceeds of approximately $11.1 million. Following the closing of the XPDB IPO and Private Placement, approximately $290.4 million was placed in the Trust Account.

In connection with the Extension Special Meeting, holders of 18,141,822 shares of XPDB Class A Common Stock elected to redeem their shares in connection with the proposal to extend the time by which the Company has to consummate an initial business combination, which resulted in 10,608,178 shares of XPDB Class A Common Stock remaining outstanding after giving effect to such redemptions.

Since the XPDB IPO, XPDB’s activity has been limited to the evaluation of business combination candidates. Based on its due diligence investigations of Montana and the industry in which it operates, including the financial and other information provided by Montana in the course of their negotiations in connection with the Merger Agreement, XPDB believes that the Business Combination with Montana is advisable and in the best interests of XPDB and its stockholders. See the section entitled “The Merger — Recommendation of the XPDB Board of Directors and Reasons for the Business Combination.”

Q: DID THE XPDB BOARD OBTAIN A THIRD-PARTY VALUATION OR FAIRNESS OPINION IN DETERMINING WHETHER OR NOT TO PROCEED WITH THE BUSINESS COMBINATION?

A: The XPDB Board did not obtain a third-party valuation or fairness opinion in connection with their determination to approve the Business Combination. The directors and officers of XPDB and XPDB’s advisors have substantial experience in evaluating the operating and financial merits of companies from a wide range of industries and concluded that their experience and backgrounds, together with the experience and sector expertise of XPDB’s

Table of Contents

financial advisors and consultants, enabled them to make the necessary analyses and determinations regarding the Business Combination. In addition, XPDB’s directors and officers and XPDB’s advisors have substantial experience with mergers and acquisitions. Accordingly, investors will be relying solely on the judgment of the XPDB Board and management and XPDB’s advisors in valuing Montana’s business.

Q: WHY IS XPDB PROVIDING STOCKHOLDERS WITH THE OPPORTUNITY TO VOTE ON THE BUSINESS COMBINATION?

A: We are seeking approval of the Business Combination pursuant to the Existing Charter. In addition, in conjunction with such stockholder vote, we must provide all XPDB Public Stockholders with the opportunity to redeem all or a portion of their Public Shares upon the consummation of the Business Combination pursuant to the applicable SEC proxy solicitation rules. We also are seeking approval of the Business Combination for purposes of complying with applicable Nasdaq listing rules requiring stockholder approval of issuances of more than 20% of a listed company’s issued and outstanding common stock.

Q: DO THE MONTANA EQUITYHOLDERS NEED TO APPROVE THE BUSINESS COMBINATION?

A: No. Under the Montana organizational documents, no approval of the Business Combination by the Montana Equityholders is required.

Q: DO I HAVE REDEMPTION RIGHTS?

A: If you are a holder of Public Shares, you have the right to demand that XPDB redeem such shares for a pro rata portion of the cash held in the Trust Account, as of two business days prior to the consummation of the Business Combination (including interest earned on the funds held in the Trust Account and not previously released to XPDB to pay taxes) upon the Closing.

Notwithstanding the foregoing, a holder of Public Shares, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act) will be restricted from seeking redemption with respect to more than 15% of the Public Shares without the consent of XPDB. Accordingly, all Public Shares in excess of 15% held by an XPDB Public Stockholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group,” will not be redeemed without the consent of XPDB.

Q: WILL HOW I VOTE AFFECT MY ABILITY TO EXERCISE REDEMPTION RIGHTS?

A: No. You may exercise your redemption rights whether you vote your shares of Public Shares for or against, or whether you abstain from voting on, the Business Combination Proposal or any other Proposal described in this proxy statement/prospectus. As a result, the Business Combination Proposal can be approved by stockholders who will redeem their Public Shares and no longer remain stockholders and the Merger may be consummated even though the funds available from the Trust Account and the number of XPDB Public Stockholders are substantially reduced as a result of redemptions by XPDB Public Stockholders.

Q: HOW DO I EXERCISE MY REDEMPTION RIGHTS?

A: If you are a holder of Public Shares and wish to exercise your redemption rights, you must demand that XPDB redeem your shares for cash no later than the second business day preceding the vote on the Business Combination Proposal by delivering your stock to XPDB’s transfer agent physically or electronically using the Depository Trust Company’s DWAC (Deposit and Withdrawal at Custodian) system. In order to exercise your redemption rights, you need to identify yourself as a beneficial holder and provide your legal name, phone number and address in your written demand. Any holder of Public Shares will be entitled to demand that such holder’s Public Shares be redeemed for a pro rata portion of the amount then in the Trust Account (which, for illustrative purposes, was approximately $ million, or approximately $ per Public Share, as of , 2023, the Record Date). Such amount, including interest earned on the funds held in the Trust Account and not previously released to XPDB to pay its taxes, will be paid promptly upon consummation of the Business Combination. However, under Delaware law, the proceeds held in the Trust Account could be subject to claims that could take priority over those of the XPDB Public Stockholders exercising redemption rights, regardless of whether such holders vote for or against the Business Combination Proposal. Therefore, the per-share distribution from the Trust Account in such a situation may be less than originally anticipated due to such claims. Your vote on any Proposal will have no impact on the amount you will receive upon exercise of your redemption rights.

xvi

Table of Contents

Any request for redemption, once made by a holder of Public Shares, may be withdrawn, with XPDB’s consent, at any time up to the time the vote is taken with respect to the Business Combination Proposal at the Special Meeting. If you deliver your Public Shares for redemption to XPDB’s transfer agent and later decide prior to the Special Meeting not to elect redemption, you may request that XPDB’s transfer agent return the Public Shares (physically or electronically).

If a holder of Public Shares properly makes a request for redemption and the Public Shares are delivered as described to XPDB’s transfer agent as described herein, then, if the Business Combination is consummated, XPDB will redeem these shares for 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 you will cease to have any rights as an XPDB stockholder (other than the right to receive the redemption amount) upon consummation of the Business Combination.

If the Business Combination is not approved or consummated for any reason, XPDB Public Stockholders who elected to exercise their redemption rights will not be entitled to redeem their shares for the applicable pro rata share of the Trust Account. In such case, XPDB will promptly return any certificates delivered by XPDB Public Stockholders who elected to redeem their shares.

For a discussion of the material U.S. federal income tax considerations for holders of Public Shares with respect to the exercise of these redemption rights, see the section entitled “Material U.S. Federal Income Tax Consequences — Tax Consequences of a Redemption of Public Shares.” The consequences of a redemption to any particular holder of Public Shares will depend on that holder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine your tax consequences from the exercise of your redemption rights, including the applicability and effect of U.S. federal, state and local and non-U.S. income and other tax laws in light of your particular circumstances.

Q: DO I HAVE APPRAISAL RIGHTS IF I OBJECT TO THE PROPOSED BUSINESS COMBINATION?

A: No. Neither XPDB stockholders nor its unit or warrant holders have appraisal rights in connection with the Business Combination under the DGCL. See the section entitled “XPDB’s Special Meeting of Stockholders — Appraisal Rights.”

Q: WHAT HAPPENS TO THE FUNDS DEPOSITED IN THE TRUST ACCOUNT AFTER CONSUMMATION OF THE BUSINESS COMBINATION?

A: After consummation of the Business Combination, the funds in the Trust Account will be used to pay holders of the Public Shares who exercise redemption rights, to pay fees and expenses incurred in connection with the Business Combination (including aggregate fees of up to approximately $6 million in the form of a Deferred Discount (as defined in the IPO Underwriting Agreement)) and for the Post-Combination Company’s working capital and general corporate purposes. As of the Record Date, there was approximately $ million in the Trust Account.

Q: HOW DO THE INITIAL STOCKHOLDERS INTEND TO VOTE ON THE PROPOSALS?

A: As of the Record Date, the Initial Stockholders of record are entitled to vote an aggregate of approximately % of the outstanding shares of XPDB Common Stock. The Sponsor and certain of XPDB’s directors have agreed to vote any Founder Shares and any Public Shares held by them as of the Record Date in favor of each of the Proposals presented at the Special Meeting. As a result, in addition to our Initial Stockholders’ Founder Shares, we would need , or %, of the Public Shares outstanding as of the Record Date to be voted in favor of each of the Proposals in order for them to be approved (assuming all issued and outstanding shares are voted).

Q: WHAT CONSTITUTES A QUORUM AT THE SPECIAL MEETING?

A: A majority of the voting power of the issued and outstanding XPDB Common Stock entitled to vote at the Special Meeting must be present, in person (which would include presence at a virtual meeting) or represented by proxy, at the Special Meeting to constitute a quorum and in order to conduct business at the Special Meeting. Abstentions will be counted as present for the purpose of determining a quorum, but broker non-votes will not. The holders of the Founder Shares, who as of the Record Date own approximately % of the issued and outstanding shares of XPDB Common Stock, will count towards this quorum. In the absence of a quorum, the chairman of the Special Meeting has power to adjourn the Special Meeting. As of the Record Date for the Special Meeting, shares of XPDB Common Stock would be required to achieve a quorum.

The Sponsor and certain of XPDB’s directors have agreed to vote any shares of XPDB Common Stock owned by them in favor of each of the Proposals presented at the Special Meeting. As a result, in addition to our Initial Stockholders’ Founder Shares, we would need 1,710,340, or 16.12%, of the 10,608,178 Public Shares outstanding as of June 30, 2023 to be voted in favor of each of the Proposals in order for them to be approved (assuming all issued and outstanding shares are voted).

Table of Contents

Q: DO ANY OF XPDB’S DIRECTORS OR OFFICERS HAVE INTERESTS IN THE BUSINESS COMBINATION THAT MAY DIFFER FROM OR BE IN ADDITION TO THE INTERESTS OF XPDB STOCKHOLDERS?

A: Certain of XPDB’s executive officers and certain directors may have interests in the Business Combination that may be different from, or in addition to, the interests of XPDB stockholders generally.

These interests include, among other things:

• If the Business Combination with Montana or another business combination is not consummated within the Completion Window, XPDB will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and the XPDB Board, dissolving and liquidating. In such event, the 7,187,500 Founder Shares purchased by the Sponsor for an aggregate purchase price of $25,000, or approximately $0.004 per share, and held by the Initial Stockholders would be worthless because the Initial Stockholders are not entitled to participate in any redemption or distribution with respect to such shares. Such Founder Shares had an aggregate market value of $76,187,500 based upon the closing price of $10.60 per share of XPDB Class A Common Stock on the Nasdaq on September 29, 2023, the most recent practicable date prior to the date of this proxy statement/prospectus.

• The Sponsor purchased an aggregate of 8,900,000 Private Placement Warrants from XPDB for an aggregate purchase price of approximately $8,900,000 (or $1.00 per warrant). Such Private Placement Warrants had an aggregate market value of $890,000 based upon the closing price of $0.10 per XPDB public warrant on the Nasdaq on September 29, 2023, the most recent practicable date prior to the date of this proxy statement/prospectus. The Private Placement Warrants would become worthless if XPDB does not consummate a business combination within the Completion Window.

• No compensation of any kind, including finder’s and consulting fees, is paid to our Sponsor, officers and directors, or any of their respective affiliates, for services rendered prior to or in connection with the completion of an initial business combination, except for reimbursement for out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations, advisory fees and consulting fees in an aggregate amount of up to $3,000,000 that will be paid to XMS Capital and TEP in connection with the Business Combination and $20,000 per month for office space, secretarial and administrative services. These amounts have not yet been paid but are accruing. Such arrangement will terminate upon the consummation of the Business Combination. From the date of the XPDB IPO until the date of the Merger Agreement, there have been no reimbursable out of pocket expenses incurred in connection with the Business Combination other than certain expenses in connection with conducting due diligence on Montana and negotiating the Merger Agreement.

• Due to the differential in the purchase price that our Sponsor and its affiliates paid for the Founder Shares and Private Placement Warrants as compared to the price of the Public Shares sold in the XPDB IPO and the substantial number of XPDB Class A Common Stock our Sponsor will receive upon conversion of the Founder Shares in connection with the Business Combination and exercise of the Private Placement Warrants, our Sponsor and its affiliates may earn a positive rate of return on their investment even if other XPDB Public Stockholders experience a negative rate of return in the Post-Combination Company, and they may therefore be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to XPDB stockholders rather than liquidate.

• One of our directors, Patrick C. Eilers, is a majority investor in TEP Montana, which owns 77,095 Montana Class B Common Units, or 4.9% of Montana’s outstanding units. TEP Montana paid approximately $4,452,825 for such units. Assuming that there is no Capital Raise or further dilution to the Montana Common Units, TEP Montana will receive approximately 1,857,301 shares of Class A Common Stock at the Closing, which, at a price of $10.00 per share, will have an aggregate value of $18,573,010 (of these shares, 1,667,256 shares having an aggregate value of $16,672,560 would be indirectly owned by Mr. Eilers). Mr. Eilers is an advisor to the Montana board of directors. Additionally, Mr. Eilers is expected to be a member of the Post-Combination Company Board following the Closing.

• The continued indemnification of current directors and officers and the continuation of directors’ and officers’ liability insurance.

The XPDB Board was aware of and considered these interests to the extent such interests existed at the time, among other matters, in approving the Merger Agreement and in recommending that the Business Combination be approved by the stockholders of XPDB. See the section entitled “The Business Combination — Interests of the Sponsor and XPDB’s Directors and Officers in the Business Combination” in this proxy statement/prospectus.

Q: WHAT DO I NEED TO DO NOW?

A: XPDB urges you to read carefully and consider the information contained in this proxy statement/prospectus, including the Annexes and the other documents referred to herein, and to consider how the Business Combination will affect you as a stockholder of XPDB. Stockholders should then vote as soon as possible in accordance with the instructions provided in this proxy statement/prospectus and on the enclosed proxy card.

Q: WHAT HAPPENS IF I SELL MY SHARES OF XPDB CLASS A COMMON STOCK BEFORE THE SPECIAL MEETING?

A: The Record Date for the Special Meeting is earlier than the date that the Business Combination is expected to be completed. If you transfer your shares of XPDB Class A Common Stock after the Record Date, but before the Special Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the Special Meeting. However, you will not be able to seek redemption of your shares of XPDB Class A Common Stock because you will no longer be able to tender them prior to the Special Meeting in accordance with the provisions described herein. If you transferred your shares of XPDB Class A Common Stock prior to the Record Date, you have no right to vote those shares at the Special Meeting or seek redemption of those shares.

Q: HOW DO I VOTE?

A: If you are a stockholder of record of XPDB as of , 2023, the Record Date for the Special Meeting, you may submit your proxy before the Special Meeting in any of the following ways, if available:

• use the toll-free number shown on your proxy card;

• visit the website shown on your proxy card to vote via the Internet; or

• complete, sign, date and return the enclosed proxy card in the enclosed postage-paid envelope.

Stockholders who choose to participate in the Special Meeting can vote their shares electronically during the meeting via live audio webcast by visiting https://www.cstproxy.com/xpdispacii/sm2023. You will need the control number that is printed on your proxy card to enter the Special Meeting. XPDB recommends that you log in at least 15 minutes before the meeting to ensure you are logged in when the Special Meeting starts.

If your shares are held in “street name” through a broker, bank or other nominee, your broker, bank or other nominee will send you separate instructions describing the procedure for voting your shares. “Street name” stockholders who wish to vote at the Special Meeting will need to obtain a proxy form from their broker, bank or other nominee.

Q: IF MY SHARES ARE HELD IN “STREET NAME” BY A BROKER, BANK OR OTHER NOMINEE, WILL MY BROKER, BANK OR OTHER NOMINEE VOTE MY SHARES FOR ME?

A: If your shares are held in “street name” in a stock brokerage account or by a broker, bank or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your broker, bank or other nominee. Please note that you may not vote shares held in “street name” by returning a proxy card directly to XPDB or by voting in person (which would include presence at a virtual meeting) at the Special Meeting unless you provide a “legal proxy”, which you must obtain from your broker, bank or other nominee.

Under the rules of the Nasdaq, brokers who hold shares in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not permitted to exercise their voting discretion with respect to the approval of matters that the Nasdaq determines to be “non-routine” without specific instructions from the beneficial owner. It is expected that all Proposals to be voted on at the Special Meeting are “non-routine” matters. Broker non-votes occur when a broker or nominee is not instructed by the beneficial owner of shares to vote on a particular proposal for which the broker does not have discretionary voting power.

Table of Contents

If you are an XPDB stockholder holding your shares in “street name” and you do not instruct your broker, bank or other nominee on how to vote your shares, your broker, bank or other nominee will not vote your shares on any of the Proposals. Such broker non-votes will be the equivalent of a vote “AGAINST” the Charter Proposal but will have no effect on the vote count for the other Proposals.

Q: WHAT IF I ATTEND THE SPECIAL MEETING AND ABSTAIN OR DO NOT VOTE?

A: For purposes of the Special Meeting, an abstention occurs when a stockholder attends the meeting in person (which would include presence at a virtual meeting) and does not vote or returns a proxy with an “abstain” vote. Abstentions will be counted as present at the Special Meeting for the purpose of determining a quorum.

If you are an XPDB stockholder who attends the Special Meeting virtually and fails to vote on the Charter Proposal, your failure to vote will have the same effect as a vote “AGAINST” such proposal.

If you are an XPDB stockholder who attends the Special Meeting virtually and fails to vote on the Business Combination Proposal, the Governance Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal and the Adjournment Proposal, your failure to vote will have no effect on such Proposal.

Q: WHAT WILL HAPPEN IF I RETURN MY PROXY CARD WITHOUT INDICATING HOW TO VOTE?

A: If you sign and return your proxy card without indicating how to vote on any particular Proposal, the XPDB Common Stock represented by your proxy will be voted “FOR” each of the Proposals presented at the Special Meeting.

Q: MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A: Yes. You may change your vote at any time before your proxy is exercised by doing any one of the following:

• send another proxy card with a later date;

• notify XPDB’s secretary in writing before the Special Meeting that you have revoked your proxy;

• submit a new proxy online before the meeting; or

• attend the Special Meeting and vote electronically by visiting https://www.cstproxy.com/xpdispacii/sm2023 and entering the control number found on your proxy card, instruction form or notice you previously received.

Any proxy that you submitted may also be revoked by submitting a new proxy by mail, or online or by telephone, not later than 11:59 p.m. Eastern Time on , 2023, or by voting online at the Special Meeting. Simply attending the Special Meeting will not revoke your proxy. If you have instructed a broker, bank or other nominee to vote your shares of XPDB Common Stock, you must follow the directions you receive from your broker, bank or other nominee in order to change or revoke your vote.

Q: WHAT HAPPENS IF I FAIL TO TAKE ANY ACTION WITH RESPECT TO THE SPECIAL MEETING?

A: If you fail to take any action with respect to the Special Meeting and the Business Combination is approved by stockholders and consummated, you will become a stockholder of the Post-Combination Company. Failure to take any action with respect to the Special Meeting will not affect your ability to exercise your redemption rights. If you fail to take any action with respect to the Special Meeting and the Business Combination is not approved, you will continue to be a stockholder of XPDB while XPDB searches for another target business with which to complete a business combination.

Q: WHAT SHOULD I DO IF I RECEIVE MORE THAN ONE SET OF VOTING MATERIALS?

A: Stockholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than

SUMMARY

This summary highlights selected information included in this proxy statement/prospectus and does not contain all of the information that may be important to you. You should read this entire document and its annexes and the other documents to which we refer before you decide how to vote.

The Business Combination and the Merger Agreement

The terms and conditions of the Business Combination are contained in the Merger Agreement, dated as of June 5, 2023, which is attached as Annex A to this proxy statement/prospectus. We encourage you to read the Merger Agreement carefully, as it is the legal document that governs the Business Combination.

On June 5, 2023, XPDB entered into the Merger Agreement with Montana and Merger Sub, pursuant to which, among other things and subject to the terms and conditions contained in the Merger Agreement, Merger Sub will merge with and into Montana, with Montana surviving the Merger as a wholly owned subsidiary of XPDB. In connection with the Closing of the Merger, XPDB will be renamed “Montana Technologies Corporation.”

XPDB has agreed to provide its stockholders with the opportunity to redeem shares of XPDB Class A Common Stock upon completion of the Business Combination.

Merger Consideration; Conversion of Securities

As part of the Business Combination, Montana Equityholders will receive the Merger Consideration. After giving effect to the conversion of all outstanding Montana Preferred Units into Montana Class B Common Units, which will occur prior to the effective time of the Merger, the Merger Consideration will be payable (i) in the case of holders of Montana Class B Common Units and Montana Class C Common Units, in the form of newly issued shares of Class A Common Stock, with a $10.00 value ascribed to each such share and which will entitle the holder thereof to one vote per share on all matters submitted to a vote of the holders of Class A Common Stock, whether voting separately as a class or otherwise, (ii) in the case of holders of Montana Class A Common Units, in the form of newly issued shares of Class B Common Stock, with a $10.00 value ascribed to each such share and which will entitle the holder thereof to a number of votes per share such that the Montana Equityholders as of immediately prior to the Closing will, immediately following the Closing, collectively own shares representing at least 80% of the voting power of all classes of capital stock of the Post-Combination Company entitled to vote on matters submitted to a vote of the stockholders of the Post-Combination Company, (iii) in the case of holders of Montana Options, each outstanding Montana Option, whether vested or unvested, will be converted into an option to purchase, upon the same terms and conditions as are in effect with respect to the corresponding Montana Option immediately prior to the Closing, including with respect to vesting and termination-related provisions, a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to the product of (x) the number of Montana Common Units underlying such option immediately prior to the Closing and (y) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per Montana Common Unit underlying such option immediately prior to the Closing divided by (B) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, and (iv) in the case of holders of Montana Warrants, each outstanding Montana Warrant will be converted into a warrant to purchase, upon the same terms and conditions as are in effect with respect to the corresponding Montana Warrant immediately prior to the Closing, including with respect to vesting and termination-related provisions, a number of shares of Class A Common Stock equal to the product of (x) the number of Montana Common Units underlying such warrant immediately prior to the Closing and (y) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, at an exercise price per share equal to (A) the exercise price per Montana Common Unit underlying such warrant immediately prior to the Closing divided by (B) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement.

members of the Post-Combination Company Board, a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known pr ice or pricing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA of more than $150,000,000, which shall be determined by a majority of the independent members of the Post-Combination Company Board in their sole discretion, equal to (i) the ratio of (x) (1) the Expected Annualized EBITDA less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000. The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing. A majority of the independent members of the Post-Combination Company Board then serving will have sole discretion in determining, among other things, the achievement of the applicable milestones, the calculations of payments of Earnout Shares to the applicable Montana Equityholders, the dates on which construction and operational viability of new production capacity is deemed completed and whether to consent to a transfer of the applicable Montana Equityholder’s right to receive Earnout Shares. Earnout Shares issuable in respect of Montana Options outstanding as of immediately prior to the effective time of the Merger may be issued to the holder of such Montana Option only if such holder continues to provide services (whether as an employee, director or individual independent contractor) to the Post-Combination Company or one of its subsidiaries through the date on which such Earnout Shares are issued, as determined by a majority of the independent members of the Post-Combination Company Board. See the section entitled “The Merger Agreement — Earnout Shares.”

Fractional Shares. No fractional shares of Class A Common Stock will be issued by virtue of the Business Combination. Each person who would otherwise be entitled to a fraction of a share of Class A Common Stock (after aggregating all fractional shares of Class A Common Stock that otherwise would be received by such holder) will instead have the number of shares of Class A Common Stock issued to such person rounded up in the aggregate to the nearest whole share of Class A Common Stock.

Ownership of the Post-Combination Company

We anticipate that, upon completion of the Business Combination, in the Assuming Minimum Redemption Scenario, the XPDB Public Stockholders will retain an ownership interest of approximately 19.0% in the Post-Combination Company, the Montana Equityholders will own approximately 68.0% of the Post-Combination Company and the Initial Stockholders will own approximately 13.0% of the Post-Combination Company. In the Maximum Contractual Redemptions Scenario, the XPDB Public Stockholders will retain an ownership interest of approximately 15.1% in the Post-Combination Company, the Montana Equityholders will own approximately 71.4% of the Post-Combination Company and the Initial Stockholders will own approximately 13.5% of the Post-Combination Company. The ownership percentages with respect to the Post-Combination Company do not take into account the issuance of any additional shares of Common Stock underlying the public Warrants. If the actual facts are different from these assumptions (which they are likely to be), these ownership percentages will be different. See “Unaudited Pro Forma Condensed Combined Financial Information.”

The following summarizes the pro forma ownership of the Post-Combination Company’s common stock as of June 30, 2023, under different redemption scenarios(1):

	Assuming Minimum Redemptions			Assuming Mid-Point Redemptions			Assuming Maximum Contractual Redemptions
Equity Capitalization Summary	Shares	%		Shares	%		Shares	%
Montana Class A Equityholders	4,818,213	8.6	%	4,818,213	8.8	%	4,818,213	9.1	%

All of the relative percentages above are for illustrative purposes only and are based upon certain assumptions as described in the section entitled “Basis of Presentation and Glossary — Share Calculations and Ownership Percentages” and, with respect to the determination of the “Assuming Maximum Contractual Redemptions Scenario,” the section entitled “Unaudited Pro Forma Condensed Combined Financial Statements.” 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.”

Recommendation of the XPDB Board of Directors

The XPDB Board has unanimously determined that the Business Combination, on the terms and conditions set forth in the Merger Agreement, is advisable and in the best interests of XPDB and its stockholders and has directed that the Proposals set forth in this proxy statement/prospectus be submitted to its stockholders for approval at the Special Meeting on the date and at the time and place set forth in this proxy statement/prospectus. The XPDB Board unanimously recommends that XPDB’s stockholders vote “FOR” the Business Combination Proposal, “FOR” the Charter Proposal, “FOR” the Governance Proposal, “FOR” the Director Election Proposal, “FOR” the Nasdaq Proposal, “FOR” the Incentive Plan Proposal, “FOR” the Employee Stock Purchase Plan Proposal and “FOR” the Adjournment Proposal, if presented. See the section entitled “The Business Combination — Recommendation of the XPDB Board of Directors and Reasons for the Business Combination.”

XPDB’s Special Meeting of Stockholders

The Special Meeting will be held on , 2023, at a.m., Central Time, in virtual format. At the Special Meeting, XPDB stockholders will be asked to vote on the Business Combination Proposal, the Charter Proposal, the Governance Proposal, the Director Election Proposal, the Nasdaq Proposal, the Incentive Plan Proposal the Employee Stock Purchase Plan Proposal and, if necessary, the Adjournment Proposal to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Business Combination Proposal, the Charter Proposal, the Nasdaq Proposal, the Incentive Plan Proposal or the Employee Stock Purchase Plan Proposal.

Stockholders will be entitled to vote or direct votes to be cast at the Special Meeting if they owned shares of XPDB Common Stock at the close of business on , 2023, which is the Record Date for the Special Meeting. Stockholders are entitled to one vote for each share of XPDB Common Stock owned at the close of business on the Record Date. If stockholders’ shares are held in “street name” or are in a margin or similar account, stockholders should contact their broker, bank or other nominee to ensure that votes related to the shares they beneficially own are properly counted. On the Record Date, there were shares of XPDB Class A Common Stock outstanding, of which were Public Shares and were Founder Shares.

A quorum of XPDB stockholders is necessary to hold a valid meeting. A quorum will be present at the Special Meeting if a majority of the voting power of all outstanding shares of capital stock of XPDB entitled to vote at the Special Meeting as of the Record Date is represented in person (which would include presence at a virtual meeting) or by proxy. Abstentions will be counted as present for the purpose of determining a quorum, but broker non-votes will not. The Initial Stockholders, who as of the Record Date own approximately of the issued and outstanding shares of XPDB Common Stock, will count towards this quorum. As of the Record Date, shares of XPDB Common Stock would be required to achieve a quorum. XPDB has entered into an agreement with the Sponsor and certain of XPDB’s directors, pursuant to which each agreed to vote any shares of XPDB Common Stock owned by them in favor of each of the Proposals presented at the Special Meeting. As a result, in addition to our Initial Stockholders’ Founder Shares, we would need , or %, of the Public Shares outstanding as of the Record Date to be voted in favor of each of the Proposals in order for them to be approved (assuming all issued and outstanding shares are voted). The Proposals presented at the Special Meeting will require the following votes:

Table of Contents

regard to each of the Business Combination Proposal, the Governance Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal or the Adjournment Proposal, if presented, will have no effect on the Business Combination Proposal, the Governance Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal or the Adjournment Proposal.

The approval of the Charter Proposal requires the affirmative vote of (i) the holders of a majority of the shares of XPDB Class B Common Stock then outstanding, voting separately as a single class, and (ii) the holders of a majority of the outstanding shares of XPDB Common Stock on the Record Date, voting together as a single class. Accordingly, a stockholder’s failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting, as well as an abstention from voting and a broker non-vote with regard to the Charter Proposal, will have the same effect as a vote “AGAINST” such proposal.

XPDB’s Directors and Executive Officers Have Financial Interests in the Business Combination

Certain of XPDB’s executive officers and certain non-employee directors may have interests in the Business Combination that may be different from, or in addition to, the interests of XPDB stockholders generally. These interests include, among other things:

• If the Business Combination with Montana or another business combination is not consummated within the Completion Window, XPDB will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and the XPDB Board, dissolving and liquidating. In such event, the 7,187,500 Founder Shares purchased by the Sponsor for an aggregate purchase price of $25,000, or approximately $0.004 per share, and held by the Initial Stockholders would be worthless because the Initial Stockholders are not entitled to participate in any redemption or distribution with respect to such shares. Certain of XPDB’s directors also own interests in the Sponsor, and would therefore indirectly benefit from the Founder Shares held by the Sponsor. Such Founder Shares had an aggregate market value of $76,187,500 based upon the closing price of $10.60 per share of XPDB Class A Common Stock on the Nasdaq on September 29, 2023, the most recent practicable date prior to the date of this proxy statement/prospectus.

• The Sponsor purchased an aggregate of 8,900,000 Private Placement Warrants from XPDB for an aggregate purchase price of approximately $8,900,000 (or $1.00 per warrant). Such Private Placement Warrants had an aggregate market value of $890,000 based upon the closing price of $0.10 per XPDB public warrant on the Nasdaq on September 29, 2023, the most recent practicable date prior to the date of this proxy statement/prospectus. Certain of XPDB’s directors also own interests in the Sponsor, and would therefore indirectly benefit from the Private Placement Warrants held by the Sponsor. The Private Placement Warrants would become worthless if XPDB does not consummate a business combination within the Completion Window.

• No compensation of any kind, including finder’s and consulting fees, is paid to our Sponsor, officers and directors, or any of their respective affiliates, for services rendered prior to or in connection with the completion of an initial business combination, except for reimbursement for out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations, advisory fees and consulting fees in an aggregate amount of up to $3,000,000 that will be paid to XMS Capital and TEP in connection with the Business Combination and $20,000 per month for office space, secretarial and administrative services for each month since the XPDB IPO that will be paid at the consummation of the Business Combination. Such arrangement will terminate upon the consummation of the Business Combination. From the date of the XPDB IPO until the date of the Merger Agreement, there have been no reimbursable out-of-pocket expenses incurred by the Sponsor in connection with the Business Combination other than certain expenses in connection with conducting due diligence on Montana.

Table of Contents

• One of our directors, Patrick C. Eilers, is a majority investor in TEP Montana, which owns 77,095 Montana Class B Common Units, or 4.9% of Montana’s outstanding units. TEP Montana paid approximately $4,452,825 for such units. Assuming that there is no Capital Raise or further dilution to the Montana Common Units, TEP Montana will receive approximately 1,857,301 shares of Class A Common Stock at the Closing, which, at a price of $10.00 per share, will have an aggregate value of $18,573,010 (of these shares, 1,667,256 shares, having an aggregate value of $16,672,560 would be indirectly owned by Mr. Eilers). Mr. Eilers is an advisor to the Montana board of directors. Additionally, Mr. Eilers is expected to be a member of the Post-Combination Company Board following the Closing.

Regulatory Approvals Required for the Business Combination

Completion of the Business Combination is subject to approval under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”). Each of Montana and XPDB have agreed to use their respective reasonable best efforts to take all actions to consummate and make effective the Business Combination as soon as reasonably practicable and to obtain as promptly as reasonably practicable all consents, registrations, approvals, clearances, permits and authorizations necessary or advisable to be obtained from any third party or any governmental entity in order to consummate the Business Combination. XPDB has further agreed to take any steps necessary to eliminate any impediments under the HSR Act or any other antitrust law that is asserted by any governmental entity so as to enable the parties to consummate the Business Combination as soon as possible.

XPDB and Montana filed Notification and Report Forms under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, with the Antitrust Division of the Department of Justice and the Federal Trade Commission on June 20, 2023, and the 30-day waiting period expired at 11:59 p.m., New York City time, on July 20, 2023. The regulatory approvals to which completion of the Business Combination are subject have been obtained and are described in more detail in the section of this proxy statement/prospectus entitled “Regulatory Approvals Required for the Business Combination.”

Appraisal Rights

Holders of XPDB Common Stock are not entitled to appraisal rights in connection with the Business Combination under Delaware law.

Material U.S. Federal Income Tax Consequences

For a discussion of the material U.S. federal income tax considerations for holders of Public Shares with respect to the exercise of redemption rights, see “Material U.S. Federal Income Tax Consequences — Tax Consequences of a Redemption of Public Shares.” The consequences of a redemption to any particular holder of Public Shares will depend on that holder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine your tax consequences from the exercise of your redemption rights, including the applicability and effect of U.S. federal, state and local and non-U.S. income and other tax laws in light of your particular circumstances.

Other Agreements

Sponsor Support Agreement

In connection with the execution of the Merger Agreement and pursuant to the terms of a Sponsor Support Agreement (the “Sponsor Support Agreement”) entered into among the Sponsor, XPDB, Montana and other holders of XPDB Class B Common Stock, a copy of which is attached to this proxy statement/prospectus as Annex D, the Sponsor and the other holders of XPDB Class B Common Stock agreed to, among other things, (i) vote at the Special Meeting any XPDB Class A Common Stock or XPDB Class B Common Stock (collectively, the “Sponsor Securities”), held of record or thereafter acquired in favor of the Proposals presented by XPDB at such meeting, (ii) be bound by certain other covenants and agreements related to the Business Combination, (iii) be bound by certain transfer restrictions with respect to the Sponsor Securities and (iv) waive certain antidilution protections with respect to the Sponsor Securities, in each case, on the terms and subject to the conditions set forth in the Sponsor Support Agreement. The quorum and voting thresholds at the Special Meeting and the Sponsor Support Agreement may make it more likely that XPDB will consummate the Business Combination. In addition, pursuant to the terms of the Sponsor Support Agreement, the Sponsor has agreed to waive its redemption rights with respect to any Sponsor Securities in connection with the completion of a Business Combination (which waiver was provided in connection with the XPDB IPO and without any separate consideration paid in connection with providing such waiver), has agreed not to transfer any Public Shares and Founder Shares held by it during the time prior to (i) Closing or (ii) the termination of the Merger Agreement, has agreed to waive anti-dilution protections and has agreed to subject certain of the shares of Class A Common Stock held by Sponsor following the conversion of the Founder Shares as of the Closing to certain vesting provisions. Specifically, the Sponsor Support Agreement provides that as of immediately prior to (but subject to) the Closing, 1,380,736 shares of Class A Common Stock held by the Sponsor following the conversion of the Founder Shares as of the Closing (the “Subject Vesting Shares”) will be subject to an earnout, with the Subject Vesting Shares vesting during the Vesting Period (i) simultaneously with the Earnout Payments made to the Montana Equityholders in a proportionate amount to the payment achieved in relation to the maximum Earnout Payment of equity interests of $200 million (the “Performance Vesting Trigger”) and (ii) up to 50% of the Subject Vesting Shares (including any vested Subject Vesting Shares from the Performance Vesting Trigger) vesting on any day following the Closing when the closing price of a share of Class A Common Stock on the Nasdaq (the “Closing Share Price”) equals or exceeds $12.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) and all remaining Subject Vesting Shares vesting when the Closing Share Price equals or exceeds $14.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like).

The Sponsor Support Agreement will terminate on the earlier of (i) the date the Business Combination becomes effective and (ii) the termination of the Merger Agreement in accordance with its terms. See the section entitled “Other Agreements — Sponsor Support Agreement.”

Summary Risk Factors

You should consider all the information contained in this proxy statement/prospectus in deciding how to vote for the Proposals presented in this proxy statement/prospectus. In particular, you should consider the risk factors described in the section entitled “Risk Factors”. Such risks include, but are not limited to:

Risks related to Montana’s business and industry, including that:

• We are a pre-revenue and development-stage company that has a limited operating history and has not yet commenced any operations, which could make it difficult to make any predictions about our future success or viability.

• We may be unable to successfully develop and commercialize our AirJoule technology.

• Our commercialization strategy relies heavily on our relationships with BASF, CATL and other third parties and partners who may not be easily replaced if our relationships terminate.

• Demand for our products may not grow or may grow at a slower rate than we anticipate.

• We are subject to risks associated with changing technology, product innovation, manufacturing techniques and operational flexibility, which may put us at a competitive disadvantage.

• We may face significant competition from established companies that have longer operating histories, customer incumbency advantages, access to and influence with governmental authorities and more capital resources than we do.

• The estimates and assumptions we use to determine the size of the total addressable market are based on a number of internal and third-party estimates, which may be incorrect and such inaccuracy could materially and adversely affect our business.

• We may need to defend ourselves against claims that we infringe, have misappropriated or otherwise violate the intellectual property rights of others, which may be time-consuming and would cause us to incur substantial costs related to potential litigation or expensive licenses.

• We may be subject to cyberattacks or a failure in our information technology and data security infrastructure that could adversely affect our business and operations.

• Increased scrutiny of environmental, social, and governance (“ESG”) matters, including our completion of certain ESG initiatives, could have an adverse effect on our business, financial condition and results of operations, result in reputational harm and negatively impact the assessments made by ESG-focused investors when evaluating us.

• Our business may be affected by force majeure events outside of our control, including labor unrest, civil disorder, war, subversive activities or sabotage, climate change, including the increased frequency or severity of natural and catastrophic events, changes in climate change policies and COVID-19 and any future widespread public health crisis may negatively impact our business and operations.

• Our business is subject to liabilities and operating restrictions arising from environmental, health and safety laws, regulations and permits across multiple jurisdictions.

• We may incur higher costs, including costs to comply with new or more stringent environmental, health and safety laws and regulations, which may decrease our profitability.

• Our failure to protect our intellectual property rights may undermine our competitive position, and litigation associated with our intellectual property rights may be costly.

Risks related to the Business Combination, including that:

• Montana’s stockholders and XPDB’s stockholders will each have a reduced ownership and voting interest after the Business Combination and will exercise less influence over management.

• There can be no assurance that the Post-Combination Company’s common stock will be approved for listing on the Nasdaq or that the Post-Combination Company will be able to comply with the continued listing standards of the Nasdaq.

Table of Contents

• The market price of shares of the Post-Combination Company’s common stock after the Business Combination may be affected by factors different from those currently affecting the prices of shares of XPDB Class A Common Stock.

• XPDB has not obtained an opinion from an independent investment banking firm, and consequently, there is no assurance from an independent source that the Merger Consideration is fair to its stockholders from a financial point of view.

• If the Business Combination’s benefits do not meet the expectations of financial analysts, the market price of our common stock may decline.

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

• XPDB directors and officers may have interests in the Business Combination different from the interests of XPDB stockholders.

• Montana directors and officers may have interests in the Business Combination different from the interests of Montana Equityholders.

• Our Sponsor may have interests in the Business Combination different from the interests of XPDB stockholders.

• The unaudited pro forma condensed combined financial information included in this proxy statement/prospectus is preliminary and the actual financial condition and results of operations after the Business Combination may differ materially.

Risks related to redemption, including that:

• If third parties bring claims against us, the proceeds held in the Trust Account could be reduced and the per share redemption amount received by XPDB Public Stockholders may be less than $10.10 per share.

• Our independent directors may decide not to enforce the indemnification obligations of our Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to XPDB Public Stockholders.

• The ability of XPDB Public Stockholders to exercise redemption rights with respect to a large number of shares could increase the probability that the Business Combination would be unsuccessful and that stockholders would have to wait for liquidation in order to redeem their stock.

SUMMARY UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following summary unaudited pro forma condensed combined financial information (the “Summary Pro Forma Information”) gives effect to the transactions contemplated by the Business Combination and related transactions. The Business Combination will be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, although XPDB will acquire all of the outstanding equity interests of Montana in the Business Combination, XPDB will be treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination will be reflected as the equivalent of Montana issuing shares for the net assets of XPDB, followed by a recapitalization whereby no goodwill or other intangible assets are recorded. Operations prior to the Business Combination will be those of Montana. The summary unaudited pro forma condensed combined balance sheet data as of June 30, 2023, gives effect to the Business Combination and related transactions as if they had occurred on June 30, 2023. The summary unaudited pro forma condensed combined statements of operations data for the six months ended June 30, 2023, and for the year ended December 31, 2022, give effect to the Business Combination and related transactions as if they had occurred on January 1, 2022, the beginning of the earliest periods presented.

The Summary Pro Forma Information has been derived from, should be read in conjunction with, the more detailed unaudited pro forma condensed combined financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Statements” in this proxy statement/prospectus and the accompanying notes thereto. The unaudited pro forma condensed combined financial information is based upon, and should be read in conjunction with, the historical financial statements and related notes of XPDB and Montana for the applicable periods included in this proxy statement/prospectus. The Summary Pro Forma Information has been presented for informational purposes only and is not necessarily indicative of what the Post-Combination Company’s financial position or results of operations actually would have been had the Business Combination and related transactions been completed as of the dates indicated. In addition, the Summary Pro Forma Information does not purport to project the future financial position or operating results of the Post-Combination Company following the reverse recapitalization.

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

• Assuming Minimum Redemptions Scenario: This presentation assumes that, after June Redemptions, no XPDB Public Stockholders will exercise redemption rights with respect to the Public Shares for a pro rata share of the funds in the Trust Account.

• Assuming Maximum Contractual Redemptions Scenario: This presentation assumes that, after the June Redemptions, 2,552,639 Public Shares are redeemed for aggregate redemption payments of $26.8 million, assuming a $10.50 per share redemption price. The Merger Agreement contains a condition to the Closing that, at the Closing, the Aggregate Transaction Proceeds shall be equal to or greater than $85 million; provided that, upon receiving proceeds in the Capital Raise equal to or in excess of such amount, this condition shall no longer apply. As certain of XPDB’s directors and the Sponsor waived their redemption rights, only 24% of potential redemptions by XPDB Public Stockholders are reflected in this presentation. This scenario includes all adjustments contained in the “Assuming Minimum Redemptions Scenario” and presents additional adjustments to reflect the effect of the Assuming Maximum Contractual Redemptions Scenario. The “Assuming Maximum Contractual Redemptions Scenario” represents the maximum number of Public Shares that may be redeemed and still satisfy the Aggregate Transaction Proceeds Condition. In the event XPDB’s Aggregate Transaction Proceeds at Closing is insufficient to meet the Aggregate Transaction Proceeds Condition due to redemptions by XPDB Public Stockholders beyond what is represented in the “Assuming Maximum Contractual Redemptions Scenario,” a condition to the Closing would not be met and the Business Combination may not be consummated. However, the

Table of Contents

Aggregate Transaction Proceeds Condition is a contractual condition that may be waived by Montana or may be modified by the parties to the Merger Agreement and if the applicable parties agree to waive or modify such condition, up to an additional 8,055,539 Public Shares may be redeemed.

The following table sets forth the historical comparative share information for XPDB and Montana on a stand-alone basis and the unaudited pro forma combined share information for the six months ended June 30, 2023 and for the year ended December 31, 2022, after giving effect to the Business Combination, assuming (i) after the June Redemptions, no XPDB Public Stockholders exercise redemption rights with respect to their Public Shares upon the consummation of the Business Combination; and (ii) after the June Redemptions, the XPDB Public Stockholders exercise their redemption rights with respect to a maximum of 2,552,639 Public Shares, or approximately $10.50 per share or $26.8 million. The Assuming Maximum Contractual Redemptions Scenario amount reflects the maximum number of Public Shares that can be redeemed without violating the conditions of the Merger Agreement.

RISK FACTORS

In addition to the other information contained in this proxy statement/prospectus, including the matters addressed under the heading “Forward-Looking Statements”, you should carefully consider the following risk factors in deciding how to vote on the Proposals presented in this proxy statement/prospectus. In this section “we,” “us” and “our” refer to Montana prior to the Business Combination and to the Post-Combination Company following the Business Combination.

Risks Related to Our Business and Our Industry

We have not yet commenced planned business line activities and have a limited operating history, which may make it difficult to evaluate the prospects for our future viability. There is no assurance that we will successfully execute our proposed strategy.

We are a pre-revenue and development-stage company. We were established as Montana Technologies LLC in 2018 and have not commenced any operations and have no history of commercializing our AirJoule technology. Our limited operating history may make it difficult for you to evaluate our current business and future prospects as we continue to grow our business. Our ability to forecast future operating results is subject to a number of uncertainties, including our ability to plan for and model future growth. We have encountered risks and uncertainties frequently experienced by growing companies in rapidly evolving industries, and we will continue to encounter such risks and uncertainties as we grow our business. If our assumptions regarding these uncertainties are incorrect, or if we do not address these risks successfully, our operating and financial results could differ materially from our expectations, and our business could suffer. Consequently, any predictions we make about our future success and our viability may not be as accurate as they could be if we had an operating history.

We will initially depend on revenue generated from a single product and in the foreseeable future will be significantly dependent on a limited number of products.

After we have successfully developed and commercialized our AirJoule technology, we will initially depend on revenue generated from our AirJoule units for the foreseeable future and will be significantly dependent on a single or limited number of products. Given that, for the foreseeable future, our business will depend on a single or limited number of products, to the extent that a particular product is not well-received by the market, our sales volume, prospects, business, results of operations and financial condition could be materially and adversely affected.

We face significant barriers in our attempts to deploy our technology and may not be able to successfully develop our technology. If we cannot successfully overcome those barriers, it could adversely impact our business and operations.

The technology behind our AirJoule units is very complex, and, while we have successfully produced a prototype unit within our test facility, we are still in the process of producing a unit that delivers dehumidified air, cooling and volume of water at the energy efficiency that we are anticipating we can achieve. If we are unable to successfully develop our technology, our operating and financial results could materially differ from our expectations and our business could suffer.

Our commercialization strategy relies heavily on our relationships with BASF, CATL and other third parties and partners who may have interests that diverge from ours and who may not be easily replaced if our relationships terminate, which could adversely impact our business and financial condition.

We anticipate that the growth of our business will depend on third-party relationships, including service providers, suppliers, consultants, referral sources, and other partners. In particular, our commercialization strategy relies heavily on our relationships with BASF and CATL. We have entered into a development agreement with BASF for the production of engineered super-porous materials that are applied as a coating to AirJoule contactors to perform the energy and water-harvesting function, and we are continuing to work with BASF to execute an ongoing development agreement to scale for mass production and global manufacturing and supply. Additionally, we have entered into a joint venture agreement with an affiliate of CATL to manufacture and commercialize our AirJoule technology in certain countries.

Table of Contents

Our heavy reliance on both of these business partners could adversely affect our business and financial condition if either of these partners chooses to terminate their relationship with us or make material changes to their businesses, products or services in a manner that is adverse to us. CATL has informed us that it intends to exit a portion of its equity investment in Montana, by selling some of its equity interests in Montana to third parties, in favor of focusing on the CAMT joint venture. This exit by CATL may have a material and adverse effect on our efforts to raise capital, which in turn could have a material adverse effect on our business and financial condition. Further, while we intend to pursue additional relationships with other third parties, identifying, negotiating and documenting relationships with third parties, as well as integrating third-party products and services requires significant time and resources, and we may not be successful in doing so.

Demand for our products may not grow or may grow at a slower rate than we anticipate.

To date, we have not had any sales of our products, but we have engaged with partners like BASF and CATL to assist us with the commercialization of our AirJoule units. Operating results are difficult to forecast as they generally depend on our assessment of the demand for our products. Our business may be affected by reductions in demand for our products and the price of competitors’ products as a result of a number of factors which may be difficult to predict. Similarly, our assumptions and expectations with respect to margins and the pricing of our AirJoule unit may not prove to be accurate. We may be unable to adopt measures in a timely manner to compensate for any unexpected shortfall in demand, which could ultimately cause our operating results to differ from expectations. If actual results differ from our estimates, analysts or investors may negatively react and our share price could be materially adversely affected.

Our financial results depend on successful project execution and may be adversely affected by cost overruns, failure to meet customer schedules, failure of our suppliers or partners to fulfill their obligations to us or other execution issues.

Commercialization of our AirJoule units is subject to a number of significant risks, including project delays, cost overruns, changes in scope, unanticipated site conditions, design and engineering issues, incorrect cost assumptions, increases in the cost of materials and labor, health and safety hazards, third-party performance issues and changes in laws or permitting requirements. If a third party or other subcontractor that we have contracted fails to fulfill its contractual obligations to us, we could face significant delays, cost overruns and liabilities. Our continued growth will depend in part on executing a greater volume of large projects, which will require us to expand and retain our project management and execution personnel and resources. If we are unable to manage these risks, we may incur higher costs, liquidated damages and other liabilities, which may decrease our profitability and harm our reputation.

COVID-19 and any future widespread public health crisis could negatively affect various aspects of our business, make it more difficult for us to meet our obligations to our future customers and result in reduced demand for our products.

Examples of how COVID-19 and any future widespread public health crisis may impact our business, results of operations and the price of our securities in the future include, but are not limited to:

• such event may interfere with our ability, or the ability of our employees, contractors, suppliers and other business partners to perform our and their respective responsibilities and obligations relative to the conduct of our business;

• such event may cause disruptions from the temporary closure or suspension of activities related to the relocation of our facilities, third-party suppliers and manufacturers or restrictions on our employee’s and other service providers’ ability to travel; and

• such event and related government responses to address any such event may cause sudden and extreme changes in the price of our securities.

New variants of COVID-19 and other future public health crises and pandemics may affect our operating and financial results in a manner that is not presently known to us or not presently considered to be a significant risk to our operations. Furthermore, our limited operating history combined with the uncertainty created by the COVID-19 pandemic significantly increases the difficulty of forecasting operating results and of strategic planning. If we are unable to effectively predict and manage the impact of the COVID-19 pandemic and other future public health crises on our business, our results of operations and financial condition may be negatively impacted.

Table of Contents

Any financial or economic crisis, or perceived threat of such a crisis, including a significant decrease in consumer confidence, may materially and adversely affect our business, financial condition and results of operations.

In recent years, global economies have suffered dramatic downturns as a result of the COVID-19 pandemic, a deterioration in the credit markets and related financial crisis, and a variety of other factors including, among other things, extreme volatility in security prices, severely diminished liquidity and credit availability, inflation, ratings downgrades of certain investments and declining valuations of others. The United States and certain other governments have taken unprecedented actions in an attempt to address and rectify these extreme market and economic conditions by providing liquidity and stability to the financial markets. The outcome of the actions taken by these governments is still ongoing and, consequently, the return of adverse economic conditions may negatively impact the demand for our technology and may negatively impact our ability to raise capital, if needed, on a timely basis and on acceptable terms or at all.

Manufacturing issues not identified prior to design finalization, long-lead procurement and/or fabrication could potentially be realized during production or fabrication and may impact our deployment cost and schedule, which could adversely impact our business.

It is possible that in the future we may experience delays and other complications from our partners and third-party suppliers in the development and manufacturing of the components and other implementing technology required for deploying our AirJoule units. Any disruption or delay in the development or supply of such components and technology could result in the delay or other complication in the design, manufacture, production and delivery of our technology that could prevent us from commercializing our AirJoule units according to our planned timeline and scale. If delays like this recur or if we experience issues with planned manufacturing activities, supply of components from third parties or design and safety, we could experience issues or delays in commencing or sustaining our commercial operations.

If we encounter difficulties in scaling our production and delivery capabilities, if we fail to develop such technologies before our competitors or if such technologies fail to perform as expected, are inferior to those of our competitors or are perceived as less safe than those of our competitors, our business, reputation and financial condition could be materially and adversely impacted.

Our sales and profitability may be impacted by, and we may incur liabilities as a result of, warranty claims, product defects, recalls, improper use of our products, or our failure to meet performance guarantees or customer safety standards.

We anticipate that our customers will require product warranties as to the proper operation and conformance to specifications of the products we manufacture or install. Failure of our products to operate properly or to meet specifications of our customers or our failure to meet our performance guarantees may increase costs by requiring additional engineering resources and services, replacement of parts and equipment or monetary reimbursement to a customer, or could otherwise result in liability to our customers. There are significant uncertainties and judgments involved in estimating warranty and performance guarantee obligations, including changing product designs, differences in customer installation processes and failure to identify or disclaim certain variables. To the extent that we incur substantial warranty or performance guarantee claims in any period, our reputation, earnings and ability to obtain future business could be materially adversely affected.

Increased scrutiny of ESG matters, including our completion of certain ESG initiatives, could have an adverse effect on our business, financial condition and results of operations, result in reputational harm and negatively impact the assessments made by ESG-focused investors when evaluating us.

We are increasingly facing more stringent ESG standards, policies and expectations, and expect to continue to do so as a listed company following the Closing with growing operations. Companies across all industries are facing increasing scrutiny from a variety of stakeholders, including investor advocacy groups, proxy advisory firms, certain institutional investors and lenders, investment funds and other influential investors and rating agencies, related to their ESG and sustainability practices. We generally experience a strong ESG emphasis among our customers, partners and competitors. Some of these stakeholders maintain standards, policies and expectations regarding environmental matters (e.g., climate change and sustainability), social matters (e.g., diversity and human rights) and corporate governance matters (e.g., taking into account employee relations when making business and investment decisions,

Table of Contents

ethical matters and the composition of the board of directors and various committees). There is no guarantee that we will be able to comply with applicable ESG standards, policies and expectations, or that we will, from the perspective of other stakeholders and the public, appear to be complying with such ESG standards, policies and expectations. If we do not adapt to or comply with investor or other stakeholder standards, policies, or expectations on ESG matters as they continue to evolve, or if we are perceived to have not responded appropriately or quickly enough to growing concern for ESG and sustainability issues, regardless of whether there is a regulatory or legal requirement to do so, we may suffer from reputational damage and our business, financial condition and/or stock price could be materially and adversely affected.

While we may at times engage in or prepare voluntary ESG initiatives and disclosures to respond to stakeholder expectations or to improve our ESG profile, such initiatives and disclosures may be costly and may not have the desired effect. Expectations regarding our management of ESG matters continues to evolve rapidly, in many instances due to factors that are beyond our control. For example, we may ultimately be unable to complete certain initiatives or targets, either on the timelines initially announced or at all, due to technological, cost, or other constraints, which may be within or outside of our control. Moreover, our ESG actions or statements may be based on expectations, assumptions, or third-party information that we currently believe to be reasonable, but which may subsequently be determined to be erroneous or be subject to misinterpretation. If we fail to, or are perceived to fail to, implement certain ESG initiatives or achieve certain ESG objectives, we may be subject to various adverse impacts, including reputational damage and potential stakeholder engagement and/or litigation, even if such initiatives are currently voluntary. Certain market participants, including major institutional investors and capital providers, use third-party benchmarks and scores to assess companies’ ESG profiles in making investment or voting decisions. Unfavorable ESG ratings could lead to increased negative investor sentiment towards us or our industry and to the diversion of investment to other industries, which could negatively impact our share price as well as our access to and cost of capital.

Moreover, because of the industry we are in, any of our operational or strategic efforts may be viewed as relating to our ESG initiatives and, even if those initiatives are undertaken voluntarily, they may still be viewed as relating to our operational and strategic efforts. This means that if we fail, or are perceived to fail, to implement certain ESG initiatives or achieve certain ESG objectives it could have a disproportionately negative impact on our business.

Actual or perceived failure to comply with ESG standards may detrimentally affect our business in a variety of ways. Among others, we could face challenges with procuring investments and financing, whether for general business purposes or for specific projects, and we could have difficulty attracting or retaining employees. Accordingly, failure to establish a sufficiently strong ESG profile relative to our peers could limit our ability to generate and successfully utilize business opportunities. We also note that divergent views regarding ESG principles are emerging in the U.S., and in particular, in U.S. state-level regulation and enforcement efforts. In the future, various U.S. regulators, state actors and other stakeholders may have views on ESG matters, the renewable energy industry, the energy transition or our business that are less favorable to our business or operations, or such stakeholders may seek to impose additional regulation and restrictions on us or our business. Any such events could have material adverse effects on our business, financial condition, results of operations, cash flow and prospects.

We also expect there will likely be increasing levels of regulation, disclosure-related and otherwise, with respect to ESG matters. We may be subject to ESG or sustainability-related regulation in multiple jurisdictions, including the U.S., and complying with these regulations in multiple jurisdictions may increase the complexity and cost of our compliance efforts. Moreover, increased regulation and increased stakeholder expectations will likely lead to increased costs as well as scrutiny that could heighten all of the risks identified in this risk factor. Additionally, many of our customers and suppliers may be subject to similar expectations, which may augment or create additional risks, including risks that may not be known to us.

Our ability to realize projects may be impaired should we fail to adhere to the common ESG standards in our industry. Moreover, such failure could result in reputational damage for us among both potential customers and investors. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations, cash flow and prospects. For further information regarding ESG-related risk, see “There are risks associated with operating in foreign countries, including those related to economic, social and/or political instability, and changes of law affecting foreign companies operating in that country. In particular, we may suffer reputational harm due to our business dealings in certain countries that have previously been associated, or perceived to have been associated, with human rights issues. Increased scrutiny and changing expectations from investors regarding environmental, social and governance (“ESG”) considerations may result in the decrease of the trading price of our securities.”

Physical and transition risks arising from climate change, including risks posed by the increased frequency or severity of natural and catastrophic events and regulations or policies related to climate change, may negatively impact our business and operations.

A natural disaster, or severe weather conditions, including in connection with climate change, or an accident that damages or otherwise adversely affects any of our current or future operations, assets, or third-party infrastructure could materially and adversely affect our business, financial condition and results of operations. Severe floods, droughts, lightning strikes, earthquakes, extreme wind conditions, severe storms, heatwaves, wildfires, monsoons and other unfavorable weather conditions or natural disasters (including those related to climate change) could damage our property and assets, or those of third parties on which we rely, or require us to shut down our current or future production facilities and/or related equipment and facilities, impeding our ability to operate and maintain our current or future production facilities and decreasing our revenues from operations. Climate change may also contribute to various chronic changes in the physical environment, such as sea-level rise or changes in ambient temperature or precipitation patterns, which may also adversely impact our or our suppliers’ operations or the operations of those who would install our products. While we may take various actions to mitigate our business risks associated with climate change and other natural and catastrophic events, this may require us to incur substantial costs and may not be successful, due to, among other things, the uncertainty associated with the longer-term projections associated with managing climate risk. For example, to the extent natural and catastrophic events or severe weather conditions become more frequent and intense, it may adversely impact the availability or cost of materials and increase the cost of insurance and other operating costs and therefore result in an increase in the costs of our products. Potential adverse impacts from climate change may also create health and safety issues for employees operating at our facilities and may lead to an inability to maintain standard operating hours.

Additionally, we expect to be subject to transition risks associated with societal efforts to mitigate or otherwise respond to climate change, including but not limited to increased laws and regulations, evolving stakeholder expectations, and changes in market demand. For example, at the international level, the United Nations-sponsored “Paris Agreement” requires member states to submit individually determined reduction goals known as “Nationally Determined Contributions” every five years after 2020. President Biden recommitted the United States to the Paris Agreement and, in April 2021, announced a goal of reducing the United States’ greenhouse emissions by 50-52% below 2005 levels by 2030. Various state and local governments have also publicly committed to furthering the goals of the Paris Agreement. In addition, the 26th Conference of the Parties concluded with the finalization of the Glasgow Climate Pact, which stated long-term global goals (including those in the Paris Agreement) to limit the increase in global average temperature and emphasized the need for reductions in greenhouse gas emissions. The full impact of these actions, and any legislation promulgated to fulfill national commitments thereunder, is uncertain at this time, and it is unclear what additional regulatory, policy, or other initiatives may be adopted or implemented in the future. New or amended international agreements, legislation, regulations or executive action addressing climate change could increase our current and future production, compliance, and other operating costs and the costs of our customers, which could decrease demand for our products. Should our customers and the markets we serve impose emissions or other environmental standards through regulation, policies, consumer preferences or otherwise, we may not be able to timely meet such standards, which could have an adverse effect upon our reputation, competitive position, and our business more broadly. There is also regulatory and budgetary uncertainty associated with certain government incentives, which, if discontinued, could adversely impact the demand for energy-efficient buildings and could increase our costs of compliance. Changing market dynamics, global and domestic policy developments, and the increasing frequency and impact of meteorological phenomena have the potential to disrupt our business, the business of our suppliers and/or customers, or otherwise adversely impact our business, financial condition, or results of operations. Any failure to adapt to changing market conditions influenced by climate change, to compete successfully with existing or new competitors (which may arise in part to meet demand driven by climate change), and to adopt new or enhanced offerings could limit our growth and have a material adverse effect on our business and prospects. Relatedly, see “We are subject to risks associated with changing technology, product innovation, manufacturing techniques, operational flexibility and business continuity, which could place us at a competitive disadvantage.”

Our business and current and future production facilities are subject to liabilities and operating restrictions arising from environmental, health and safety laws, regulations, and permits. We will be subject to environmental, health and safety laws and regulations in multiple jurisdictions, which impose substantial compliance requirements on our operations. Our operating costs could be significantly increased in order to comply with new or more stringent regulatory standards in the jurisdictions in which we operate.

Our business and our and our partners’ current and future production facilities are and will be subject to various foreign, federal, state and local environmental, health and safety (“EHS”) laws, regulations, guidelines, policies, directives, permits, and other requirements governing or relating to, among other things:

• the protection of wildlife, including migratory birds, bats, and threatened and endangered species, such as desert tortoises, or protected species such as eagles, and other protected plants or animals whose presence or movements often cannot be anticipated or controlled;

• water use, and discharges of pollutants into nearby wetlands or navigable waters;

• hazardous or toxic substances or wastes and other regulated substances, materials, or chemicals, including those existing on a site prior to our use or occupancy of the site or releases thereof into the environment;

• land use, zoning, building, and transportation laws and requirements, which may mandate conformance with sound levels, radar and communications interference, hazards to aviation or navigation, or other potential nuisances;

• the presence or discovery of archaeological, historical, religious, or cultural artifacts or resources at or near our facilities;

• the protection of workers’ health and safety; and

• the proper decommissioning and reclamation of a site at the end of its useful life.

Pursuant to these laws, we may be required to obtain various permits from certain regulatory agencies for our operations. If our facilities and operations do not comply with such laws, regulations, requirements or permits, each of which may vary across the jurisdictions in which we operate, we may be required to pay significant administrative or civil penalties or fines, curtail or cease operation of the affected facilities, make costly modifications to such facilities, or seek new or amended permits for our operations. Violations of environmental and other laws, regulations, and permit requirements, including certain violations of laws protecting wetlands, migratory birds, and threatened or endangered species, may also result in criminal sanctions or injunctions. The global EHS regulatory environment continues to change, and these laws and regulations, and the enforcement thereof, have tended to become more stringent over time. It is possible that new standards could be imposed, or interpretation or enforcement of existing laws and regulations could change, making the regulatory environment more stringent. Such changes could result in higher operating expenses, the obsolescence of our products or an interruption or suspension of our operations and have an adverse effect on our business, financial condition and results of operations.

Our current and future operations also carry inherent EHS risks, including the potential for related civil litigation, regulatory compliance, remediation orders, fines, and other penalties. For instance, equipment or machinery at our current facility or any future facilities could malfunction or experience other unplanned events that cause spills or environmental contamination, which in turn could result in personal injury, fines, or property damage. EHS laws and regulations have generally become more stringent over time, and we expect this trend to continue. We may need to incur significant capital and operating costs to keep our current facility and any future facilities in compliance with such EHS laws and regulations. If it is not economical to make those expenditures, or if we violate any applicable EHS laws and regulation, it may be necessary to retire or suspend operations of our facilities or restrict or modify our operations to obtain or maintain compliance, either of which could have a material adverse effect on our business, financial condition, results of operations, cash flow and prospects.

Additionally, we may be held liable for related investigatory and clean-up costs for any property where there has been a release or potential release of a hazardous substance, regardless of whether we knew of or caused the release or potential release, even in the absence of negligence. We could also be liable for other costs, including fines, personal injury, property damage, damage to natural resources or the costs of certain health studies. In addition, some environmental laws place a lien on a contaminated site in favor of the government as security for damages and costs it

Table of Contents

may incur relating to contamination and clean-up. Contained or uncontained hazardous substances on, under, or near our facilities, regardless of whether we own or lease the property, or the inability to remove or otherwise remediate such substances may restrict or eliminate our ability to operate our projects.

Furthermore, foreign, federal, state, and local governments are increasingly regulating and restricting the use of certain chemicals, substances, and materials. Some of these policy initiatives could impact our business. For example, laws, regulations, or other policy initiatives might restrict substances found within component parts to our products, in which event we would be required to comply with such requirements, which could in turn require changes to our products and increase our production and operating costs.

Many foreign, federal, state, and local environmental laws, regulations, and permitting requirements will apply to development of our future facilities and could negatively impact our ability to develop and operate our future facilities. Violations of environmental and other laws, regulations, and permit requirements; the discovery of threatened or endangered species or their habitat, hazardous materials, or archaeological, historical, or cultural artifacts at our future facility sites; or adverse effects on public or private lands could also result in negative publicity for us, which could, in turn, limit our ability to develop our facilities and acquire interests in additional facilities in the future.

Our past and potential future transactions with foreign-based commercial partners and investors may be subject to review by the Committee on Foreign Investment in the United States (“CFIUS”). CFIUS actions, including potentially imposing restrictions or conditions on these transactions, or forcing us to terminate these transactions, could adversely impact our business and operations.

CFIUS has authority to review certain direct or indirect foreign investments in U.S. businesses for national security considerations. Among other things, CFIUS is authorized to require mandatory filings for certain foreign investments in the United States and to self-initiate national security reviews of certain foreign direct and indirect investments in U.S. businesses if the parties to such investments choose not to file voluntarily. With respect to transactions that CFIUS determines present unresolved national security concerns, CFIUS has the power to suspend transactions, impose mitigation measures or recommend that the president of the United States block pending transactions or order divestitures of completed transactions when national security concerns cannot be mitigated. Whether CFIUS has jurisdiction to review an acquisition or investment transaction depends on, among other factors: the nature and structure of the transaction; whether the target entity or assets constitute a U.S. business; the level of beneficial ownership and voting interests acquired by foreign persons; and the nature of any information, control, access or governance rights that the transaction affords foreign persons. For example, any transaction that could result in foreign “control” (as such term is defined in the CFIUS regulations) of a U.S. business is within CFIUS’s jurisdiction, including such a transaction carried out through a joint venture. In addition, CFIUS has jurisdiction over certain investments that do not result in control of a U.S. business by a foreign person but that afford a foreign person certain access, involvement or governance rights in a “TID U.S. business,” that is, a U.S. business that: (1) produces, designs, tests, manufactures, fabricates, or develops one or more “critical technologies;” (2) owns, operates, manufactures, supplies or services certain “covered investment critical infrastructure;” or (3) maintains or collects, directly or indirectly, “sensitive personal data” of U.S. citizens.

We have in the past entered into, and may in the future enter into, commercial arrangements with foreign persons including, for example, our development agreement with BASF and our joint venture with an affiliate of CATL. In addition, foreign investors have invested in us in the past and may invest in us in the future, and we may continue to pursue partnerships and operations outside of the United States.

CFIUS has broad discretion to interpret its regulations, and CFIUS policies and practices are evolving rapidly. As a result, we cannot predict whether CFIUS may seek to review our past or potential future transactions involving a foreign person, even if such transactions did not or will not require a mandatory CFIUS filing at the time of the transaction. Any review by CFIUS of one or more of our past or potential future transactions involving a foreign person may have outsized impacts on, among other things, the certainty, timing, feasibility and cost of the transaction in question, and there can be no assurance that we and the foreign person will be able to maintain (if the transaction has already been completed), or proceed with (if the transaction is pending), the transaction on acceptable terms or at all.

We expect to be dependent on a limited number of customers and end markets. A decline in revenue from, or the loss of, any significant customer, could have a material adverse effect on our financial condition and operating results.

We are in the process of developing our technology and do not yet have any customers. We expect to depend upon a small number of customers for a substantial portion of our future revenue. Accordingly, a decline in revenue from, or the loss of, any significant customer could have a material adverse effect on our financial condition and operating results. We cannot assure that prospective customers will ultimately utilize our products and services or enter into contracts with us for such products and services on acceptable terms or at all.

There can also be no assurance that our efforts to secure new customers, including through acquisitions, will succeed in reducing our customer concentration. Acquisitions are also subject to integration risk, and revenues and margins could be lower than we anticipate. Failure to secure business from new customers in any of our end markets would adversely impact our operating results.

We may depend on sole-source and limited-source suppliers for key components and products. If we are unable to source these components and products on a timely basis or at acceptable prices, we will not be able to deliver our products to our customers and production time and production costs could increase, which may adversely affect our business.

Our manufacturing processes rely on many materials. We purchase, and will continue to purchase, a significant portion of our materials, components and finished goods used in our production facilities from a few suppliers, some of which are single-source suppliers. As certain materials are highly specialized, the lead time needed to identify and qualify a new supplier is typically lengthy and there is often no readily available alternative source. We do not generally have long-term contracts with our suppliers and substantially all of our purchases are on a purchase order basis. Suppliers may extend lead times, limit supplies, place products on allocation or increase prices due to commodity price increases, capacity constraints or other factors and could lead to interruption of supply or increased demand in the industry.

Additionally, the supply of these materials may be negatively impacted by increased trade tensions between the U.S. and its trading partners, particularly China. In the event that we cannot obtain sufficient quantities of materials in a timely manner, at reasonable prices or of sufficient quality, or if we are not able to pass on higher materials costs to our customers, our business, financial condition and results of operations could be adversely impacted.

We may face supply chain competition, including competition from businesses in other industries, which could result in insufficient inventory and negatively affect our results of operations.

Certain of our suppliers also supply systems and components to other businesses. As a relatively low-volume purchaser of certain of these parts and materials, we may be unable to procure a sufficient supply of the items we need in the event that our suppliers fail to produce sufficient quantities to satisfy the demands of all of their customers, which could materially adversely affect our business, financial condition and results of operations.

We are subject to risks associated with changing technology, product innovation, manufacturing techniques, operational flexibility and business continuity, which could place us at a competitive disadvantage.

The industries in which we operate are subject to rapid technological change, evolving industry standards and practices and changing customer needs and preferences. The success of our business will depend, in part, on our ability to adapt and respond effectively to these changes on a timely basis. We may introduce significant changes to our AirJoule unit or develop and introduce new and unproven products, including using technologies with which we have little or no prior development or operating experience. If we are unable to develop and sell new technology, features and functionality for our AirJoule unit that satisfy our customers and that keep pace with rapid technological and industry change, our revenue and operating results could be adversely affected. If new technologies emerge that deliver competitive solutions at lower prices, more efficiently, more conveniently or more securely, it could adversely impact our ability to compete and place us at a competitive disadvantage.

We expect to incur research and development costs and devote resources to identifying and commercializing new products, which could reduce our profitability and may never result in revenue to us.

We will require significant capital to develop and grow our business and we expect to incur significant expenses, including those relating to developing and commercializing our AirJoule units, research and development, production, sales, maintenance and service and building the AirJoule brand. Our current estimates of the costs associated with development and commercialization could prove inaccurate, and that could impact the cost of our technology and of our business overall. If we are unable to efficiently design, develop, commercialize, license, market and deploy our technology in a cost-effective manner, our margins, profitability and prospects would be materially and adversely affected.

Our long-term success will depend ultimately on implementing our business strategy and operational plan, as well as our ability to generate revenues, achieve and maintain profitability and develop positive cash flows.

We are a new company with a history of losses. We have incurred a net loss of approximately $2.8 million and $2.3 million for the year ended December 31, 2022, and 2021, respectively. Although we were established as Montana Technologies LLC in 2018, we did not develop our first prototype of the AirJoule unit until June of 2021 and have not yet begun commercialization. We expect to continue to incur operating and net losses each quarter until we have begun a large-scale delivery of AirJoule units and have realized increased market adoption of energy-efficient air conditioning and water-stress technologies. Even if we can successfully develop our AirJoule unit and attract customers, there can be no assurance that we will be able to generate net income.

We expect that we will continue to incur losses in future periods as we:

• design, develop, market, commercialize and begin to sell AirJoule units;

• continue to utilize and develop potential new relationships with third-party partners for supply and manufacturing;

• build up inventories of parts and components for AirJoule units;

• expand our design, development, installation and servicing capabilities;

• further develop our proprietary technology;

• develop our distribution network;

• increase our general and administrative functions to support our growing operations and to operate as a public company; and

• expand our facility to enhance our efficiency and capabilities for assembly of AirJoule units.

Because we will incur the costs and expenses from these efforts before we receive any incremental revenues with respect thereto, our losses in future periods could be significant. In addition, we may find that these efforts are more expensive than we currently anticipate or that these efforts may not result in additional revenues, which could further increase our losses.

We may lack sufficient funds to achieve our planned business objectives. Our ability to continue as a going concern is dependent on (i) continued financial support from our shareholders and other related parties, (ii) raising capital via external financing and/or (iii) attaining profitable operations. We may seek to raise further funds through equity or debt financing, joint ventures, production sharing arrangements or other means. Any inability to access the capital or financial markets may limit our ability to fund our ongoing operations and execute our business plan to pursue investments that we may rely on for future growth.

We have limited capital resources and operations. From time to time, we may seek additional financing to provide the capital required to expand production of our business operations, development initiatives and/or working capital, as well as to repay outstanding loans if cash flow from operations is insufficient to do so. We cannot predict with certainty the timing or amount of any such capital requirements.

Table of Contents

We may in the future require access to capital markets and debt financing as a source of liquidity for investments and expenditures. If we do not raise sufficient capital to fund our ongoing development activities, it is likely that we will be unable to carry out our business plans. We may not be able to obtain additional financing on terms acceptable, or at all. Even if we obtain financing for near term operations, we may require additional capital beyond the near term. If we are unable to raise capital when needed, or if our ability to access required capital were to become significantly constrained, we could incur material borrowing cost and our business, financial condition and results of operations would be materially adversely affected, and it could force us to reduce or discontinue our operations.

Actual capital costs, operating costs, production and economic returns may differ significantly from those we have anticipated and future development activities may not result in profitable operations.

The actual operating costs of manufacturing, commercializing and distributing AirJoule on a commercial scale will depend upon a variety of factors, such as changes in the availability of and price of materials and changes in governmental regulation, including taxation, environmental, permitting and other regulations and other factors, many of which are beyond our control. Due to any of these or other factors, our capital and operating costs may be significantly higher than those initially estimated by management. As a result of higher capital and operating costs, our financing ability may be impacted, and this may be further affected by lower commodity prices in the international markets that could impact production or economic returns which may differ significantly from management’s expectations and there can be no assurance that any of our development activities will result in profitable operations.

Our long-term success depends, in part, on our ability to negotiate and enter into sales agreements with, and deliver our products to, customers on commercially viable terms. There can be no assurance that we will be successful in securing such agreements.

Our success depends, in part, on our ability to acquire and retain new customers and to do so in a cost-effective manner. In order to obtain and expand our customer base, we must appeal to, acquire and enter into sales agreements with third-party customers on commercially viable terms, either directly or through third-party distributors. We expect to make significant investments related to customer acquisition in the future. If we fail to deliver and market a robust product that appeals to customers, or if customers do not perceive AirJoule units to be of high value and quality, we may be unable to acquire or retain customers. If we are unable to acquire or retain customers sufficient to grow our business, we may be unable to generate the scale necessary to achieve operational efficiency. Consequently, our prices may increase, or may not decrease to levels sufficient to generate customer interest, and total revenue may decrease and margins and profitability may decline. As a result, our business, financial condition and results of operations may be materially and adversely affected.

Exchange rate fluctuations may materially affect our results of operations and financial condition.

We anticipate that our partner and customer contracts will primarily be denominated in U.S. dollars, and therefore substantially all of our revenue will not be subject to foreign currency risk. However, a strengthening of the U.S. dollar could increase the real cost of AirJoule units to our customers outside of the United States, which could adversely affect our operating results. In addition, a portion of our operating expenses are expected to be incurred and a portion of our assets are expected to be held outside the United States. These operating expenses and assets would be denominated in foreign currencies and are subject to fluctuations due to changes in foreign currency exchange rates. If we are not able to successfully hedge against the risks associated with currency fluctuations, our operating results could be adversely affected.

If we fail to retain our key personnel or if we fail to attract additional qualified personnel, we may not be able to achieve our anticipated level of growth and our business could suffer.

Our success depends to a significant extent on our ability to attract and retain talent, specifically in senior management and skilled technical, engineering, project management and other key roles. Macroeconomic conditions, specifically labor shortages, increased competition for employees and wage inflation could have a material impact on our ability to attract and retain talent, our turnover rate and the cost of operating our business. If we are unable to attract and retain sufficient talent, minimize employee turnover or manage wage inflation, it could have a material adverse effect on our business, financial condition, results of operations or prospects.

Table of Contents

We may face significant competition from established companies with longer operating histories, customer incumbency advantages, access to and influence with governmental authorities and more capital resources than we do.

The markets for energy-efficient air conditioning and generation of potable water are evolving and highly competitive. We expect competition to increase in the future from established competitors and new market entrants. This could negatively impact our ability to compete in these markets. We will face competition from other water generation and comfort cooling companies that offer standalone air conditioning and water production solutions and services. In addition, we may face competition from niche companies and new market entrants that offer point products that attempt to address the specific problems that our AirJoule unit attempts to solve.

Many of our existing competitors have, and our potential competitors could have, substantial competitive advantages such as greater name recognition, longer operating histories, larger sales and marketing budgets and resources, greater customer support resources, lower labor and development costs, larger and more mature intellectual property portfolios and substantially greater financial, technical and other resources.

Some of our larger competitors also have substantially broader product lines and market focus and will therefore not be as susceptible to downturns in a particular market. Conditions in our market could change rapidly and significantly as a result of technological advancements, partnering by our competitors, or continuing market consolidation. New start-up companies that innovate and/or large companies that are making significant investments in research and development may invent similar or superior products and technologies that compete with our AirJoule units. In addition, some of our competitors may enter into new alliances with each other or may establish or strengthen cooperative relationships with agency partners, technology and application providers in complementary categories or other parties. Any such consolidation, acquisition, alliance or cooperative relationship could lead to pricing pressure, a loss of market share or a smaller addressable share of the market, all of which could harm our ability to compete and may materially affect our results of operations and financial condition.

Any failure by our management to properly manage our growth could have a material adverse effect on our business, operating results and financial condition.

We may experience rapid growth and organizational change, which may place significant demands on our management and our operational and financial resources. Our success will depend in part on our ability to manage this growth effectively. We will require significant capital expenditures and valuable management resources to grow without undermining our culture of innovation and teamwork, which has been central to our growth so far. If we fail to manage our anticipated growth and change in a manner that preserves our culture, it could negatively affect our reputation and ability to retain and attract customers and employees. We also intend to expand our international operations in the future. Our expansion may place a significant strain on our managerial, administrative, financial and other resources. If we are unable to manage our growth successfully, our business and results of operations could suffer.

Damage to our reputation or brand image could adversely affect our business.

Our reputation will be one of our key assets. Our ability to attract and retain customers will be highly dependent upon the external perceptions of our level of service, trustworthiness, business practices, financial condition and other subjective qualities. Negative perceptions or publicity regarding these or other matters, including from actual or alleged conduct by us or our employees, could damage our reputation. Any resulting erosion of trust and confidence among customers, business partners, regulators and other parties important to the success of our business could make it difficult for us to attract customers and business partners, which could have a material adverse effect on our business, financial condition and results of operations.

The occurrence of significant events against which we may not be fully insured could have a material adverse effect on our business, financial condition and results of operations.

We may be subject, in the ordinary course of business, to losses resulting from product liability, accidents, acts of God and other claims against us, for which we may have no insurance coverage. We cannot be certain that any future insurance coverage we obtain will be sufficient to cover all future losses or claims against us. A loss that is uninsured or which exceeds policy limits may require us to pay substantial amounts, which could adversely affect our business, financial condition and results of operations.

Table of Contents

The threat of global economic, capital markets and credit disruptions pose risks to our business.

Our performance will depend on the financial health and strength of our customers, which in turn will be dependent on the economic conditions of the markets in which we and our customers operate. A decline in the global economy, difficulties in the financial services sector and credit markets, continuing geopolitical uncertainties and other macroeconomic factors all affect the spending behavior of potential customers. The economic uncertainty in Europe, the United States, India, China and elsewhere arising out of the COVID-19 pandemic and increased monetary inflation may cause end-users to further delay or reduce technology purchases.

We may also face risks from financial difficulties or other uncertainties experienced by our suppliers, distributors or other third parties on which we rely. If third parties are unable to supply us with required materials or components or otherwise assist us in operating our business, our business could be harmed.

Inflation may increase our operating costs.

Inflation rates, particularly in the United States, have increased recently to levels not seen in years. Increased inflation may result in decreased demand for our products and services, increased operating costs (including our labor costs), reduced liquidity and limitations on our ability to access credit or otherwise raise debt and equity capital. In addition, the United States Federal Reserve has raised, and may again raise, interest rates in response to concerns about inflation. Increases in interest rates, especially if coupled with reduced government spending and volatility in financial markets, may have the effect of further increasing economic uncertainty and heightening these risks.

Our business may be adversely affected by force majeure events outside of our control, including labor unrest, civil disorder, war, subversive activities or sabotage, extreme weather conditions, fires, floods, explosions or other catastrophes or epidemics.

The occurrence of one or more natural disasters, including and not limited to tornadoes, hurricanes, fires, floods and earthquakes, unusual weather conditions, pandemics and endemic outbreaks, terrorist attacks or disruptive political events in certain regions where our facilities are located, or where our third-party contractors’ and suppliers’ facilities are located, could adversely affect our business. The continuing conflict arising from the invasion of Ukraine by Russia, or strategic competition and tensions between China, the United States, Taiwan or other countries have also contributed to uncertainty in the geopolitical and regulatory landscape. Such conflicts and tensions could adversely impact macroeconomic conditions, give rise to regional instability and result in heightened economic tariffs, sanctions and import-export restrictions from the United States and the international community in a manner that adversely affect us, including to the extent that any such actions cause material business interruptions or restrict our ability in these regions to conduct business with certain suppliers or vendors. Additionally, such conflict or sanctions may significantly devalue various global currencies and have a negative impact on economies in geographies in which we do business.

Similarly, other events such as terrorist attacks, actual or threatened acts of war or the escalation of current hostilities, or any other military or trade disruptions impacting our domestic or foreign suppliers of components of our products, may impact our operations by, among other things, causing supply chain disruptions and increases in commodity prices, which could adversely affect our raw materials or transportation costs. These events also could cause or act to prolong an economic recession in the United States or abroad. Any future disaster recovery and business continuity plans we may put in place may prove inadequate in the event of a serious disaster or similar event, and, more generally, any of these events could cause consumer member confidence and spending to decrease, which could adversely impact our operations.

If the estimates and assumptions we use to determine the size of our total addressable market are inaccurate, our future growth rate may be affected and the potential growth of our business may be limited.

Our estimates for our total addressable market are based on a number of internal and third-party estimates, including the number of potential customers who have expressed interest in licensing our technology, assumed prices and production costs for our products, our ability to leverage our current logistical and operational processes and general market conditions. However, our assumptions and the data underlying our estimates may not be correct and the conditions supporting our assumptions or estimates may change at any time, thereby reducing the predictive accuracy

Table of Contents

of these underlying factors. As a result, our estimates of the annual total addressable market for our products, as well as the expected growth rate for the total addressable market for our products, may prove to be incorrect, which could materially and adversely affect our business.

Risks Related to Legal, Compliance and Regulations

There are risks associated with operating in foreign countries, including those related to economic, social and/or political instability, and changes of law affecting foreign companies operating in that country. In particular, we may suffer reputational harm due to our business dealings in certain countries that have previously been associated, or perceived to have been associated, with human rights issues. Increased scrutiny and changing expectations from investors regarding environmental, social and governance (“ESG”) considerations may result in the decrease of the trading price of our securities.

We are currently party to a joint venture with an affiliate of CATL, a Chinese battery manufacturer and technology company, and a development agreement with BASF, an international chemical producer headquartered in Germany. We may continue to pursue partnerships and operations outside of the United States, particularly with suppliers and partners that are located or operate in China. Accordingly, we are subject to risks associated with operating in foreign countries, including:

• fluctuations in currency exchange rates;

• limitations on the remittance of dividends and other payments by foreign subsidiaries and joint ventures;

• additional costs of compliance with local regulations;

• historically, in certain countries, higher rates of inflation than in the United States;

• changes in the economic conditions or consumer preferences or demand for our products in these markets;

• restrictive actions by multinational governing bodies, foreign governments or subdivisions thereof;

• changes in U.S. and foreign laws regarding trade and investment, including with respect to taxation, import and export tariffs, energy use, land use rights, intellectual property, network security and other matters;

• less robust protection of our intellectual property under foreign laws;

• geopolitical events, including natural disasters, public health issues, acts of war, nationalism and terrorism, social unrest or human rights issues; and

• difficulty in obtaining distribution and support for our products.

In addition, our operations outside the United States are subject to the risk of new and different legal and regulatory requirements in local jurisdictions, potential difficulties in staffing and managing local operations and potentially adverse tax consequences. The costs associated with operating our continuing international business could adversely affect our results of operations, financial condition and cash flows in the future.

There is an increasing focus from certain investors, employees, partners and other stakeholders concerning ESG matters. While we have internal efforts directed at ESG matters and preparations for increased required future ESG disclosures to an extent we believe to be appropriate at this time, we could be perceived to be not acting responsibly in connection with ESG matters, which could negatively impact us and our reputation. Moreover, the SEC has recently proposed, and may continue to propose, certain mandated ESG reporting requirements, such as the SEC’s proposed rules designed to enhance and standardize climate-related disclosures, which, if finally approved, would significantly increase our compliance and reporting costs and may also result in disclosures that certain investors or other stakeholders deem to negatively impact our reputation or that harm our stock price. For further information regarding ESG-related risk, see “Increased scrutiny of ESG matters, including our completion of certain ESG initiatives, could have an adverse effect on our business, financial condition and results of operations, result in reputational harm and negatively impact the assessments made by ESG-focused investors when evaluating us.”

Table of Contents

Our business may require numerous permits, licenses and other approvals from various governmental agencies, and the failure to obtain or maintain any of them, or delays in obtaining them, could materially adversely affect us.

Regulatory risks associated with our business include:

• our ability to obtain and maintain applicable permits, approvals, licenses or certifications from regulatory agencies, if required;

• regulatory delays, delays imposed as a result of regulatory inspections and changing regulatory requirements may cause a delay in our ability to fulfill our orders or may cause manufacturing plans to not be completed at all, many of which may be out of our control, including changes in governmental regulations or in the status of our regulatory approvals or applications or other events that force us to cancel or reschedule production, any of which could have an adverse impact on our business and financial condition;

• regulatory, availability and other challenges may delay our progress in establishing the number of AirJoule units we are able to produce, and such challenges could have an adverse effect on our ability to grow our business; and

• challenges as a result of regulatory processes or in our ability to secure the necessary permissions to deliver our products could adversely affect our business.

Any of these risk factors could have a material adverse effect on our business.

Our failure to comply with applicable anti-corruption, anti-bribery, anti-money laundering, antitrust, foreign investment and similar laws and regulations could negatively impact our reputation and results of operations.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended (“FCPA”), the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, and other anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption and anti-bribery laws have been enforced aggressively in recent years. These laws are interpreted broadly to prohibit companies and their employees and third-party intermediaries from authorizing, promising, offering or providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. As we increase our international sales and business and sales to the public sector, we may engage with partners and third-party intermediaries to market our services and to obtain necessary permits, licenses and other regulatory approvals. In addition, we or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners and agents, even if we do not explicitly authorize such activities.

While we have policies and procedures to address compliance with such laws, our employees and agents could violate our policies and applicable law, for which we may be ultimately held responsible. As we increase our international sales and business, our risks under these laws may increase.

Noncompliance with anti-corruption, anti-bribery or anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage and other collateral consequences. If any subpoenas or investigations are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could be materially harmed. Responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense costs and other professional fees. Enforcement actions and sanctions could further harm our business, results of operations and financial condition.

Our business could be adversely affected by trade wars, trade tariffs or other trade barriers.

Trade barriers, embargoes, tariffs or shortages and other general economic or political conditions may limit our ability to obtain key components for our AirJoule units or significantly increase freight charges, raw material costs and other expenses associated with our business, which could materially and adversely affect our business, financial condition, prospects and results of operations.

Risks Related to Intellectual Property and Technology

Our patent applications may not result in issued patents, and our issued patents may not provide adequate protection, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours.

Our patent applications may not result in issued patents, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours. The registration of patents involves complex legal and factual questions and the breadth of claims allowed is uncertain. As a result, we cannot be certain that our patent applications will result in patents being issued, or that our patents and any patents that may be issued to us will afford protection against competitors with similar technology. Numerous patents and pending patent applications owned by others exist in the fields in which we have developed and is and will be developing our technology. Many of these existing patents and patent applications might have priority over our patent applications and could subject our patent applications to rejection. Furthermore, patent applications filed in foreign countries are subject to laws, rules and procedures that differ from those of the United States, and thus we cannot be certain that foreign patent applications related to issued U.S. patents will be issued.

Many patent applications in the United States are maintained in secrecy for a period of time after they are filed, and since publication of discoveries in the scientific or patent literature tends to lag behind actual discoveries by several months, we cannot be certain that we will be the first creator of inventions covered by any patent application we make or that we will be the first to file patent applications on such inventions. Because some patent applications are maintained in secrecy for a period of time, there is also a risk that we could adopt a technology without knowledge of a pending patent application, which technology would infringe a third-party patent once that patent is issued.

Even if our patent applications succeed and we are issued patents in accordance with them, it is still uncertain whether these patents will be contested, circumvented, invalidated or limited in scope in the future. In addition to those who may claim priority, any of our existing or pending patents may also be challenged by others on the basis that they are otherwise invalid or unenforceable. The rights granted under any issued patents may not provide us with meaningful protection or competitive advantages, and some foreign countries provide significantly less effective patent enforcement than what the United States provides. In addition, the claims under any patents that issued to us may not be broad enough to prevent others from developing technologies that are similar or that achieve results similar to ours. The intellectual property rights of others could also bar or limit us from licensing, exploiting or enforcing any patents issued to us. In addition, patents issued to us may be infringed upon or designed around by others and others may obtain patents that it needs to license or design around, either of which would increase costs and may adversely affect our business, financial condition, prospects and results of operations.

Our failure to protect our intellectual property rights may undermine our competitive position, and litigation associated with our intellectual property rights may be costly.

We seek to protect proprietary technologies primarily through patents and trade secrets. Patent protection may not be available or appropriate for some of the products or technology we are developing. While we own several patents and pending patent applications in the United States and in foreign jurisdictions, these applications do not ensure the protection of our intellectual property for a number of reasons, including that there may be prior art of which we are not aware or there may be other patents existing in the patent landscape that affect our freedom to operate. If we must spend significant time and money prosecuting, protecting or enforcing our patents, designing around patents held by others or licensing, potentially for large fees, patents or other proprietary rights held by others, our business and financial prospects may be harmed. Additionally, pending applications may not be issued or may be issued with claims significantly narrower than we currently seek. Similarly, patents for which claims have been allowed may be successfully challenged and invalidated. Unless and until our pending applications issue, their protective scope is impossible to determine and, even after issuance, their protective scope may be limited. Also, litigation may be necessary to enforce our intellectual property rights or determine the validity and scope of the proprietary rights of others. Such litigation may result in our intellectual property rights being challenged, limited in scope or declared invalid or unenforceable. We cannot be certain that the outcome of any litigation will be in our favor, and an adverse determination in any such litigation could impair our intellectual property rights and may harm our business, prospects and reputation.

Table of Contents

In addition, our success depends in large part on our proprietary information, including certain processes, formulations and other know-how developed over years of research and development. We rely heavily on trade secrets, especially in cases where we believe patents or other forms of registered intellectual property protection may not be appropriate or obtainable. However, trade secrets are difficult to protect. We employ various methods to protect such intellectual property, such as entering into confidentiality agreements with certain third parties and our employees, and controlling access to, and distribution of, our proprietary information. We cannot guarantee that we have entered into such agreements with each party that may have or has had access to our trade secrets or proprietary technology and processes. We cannot assure you that these agreements will provide meaningful protection for our trade secrets, know-how, or other proprietary information in the event of any unauthorized use, misappropriation, or disclosure of such trade secrets, know-how, or other proprietary information. There can be no assurance that such third parties will not breach their agreements with us, that we will have adequate remedies for any breach, or that our trade secrets, know-how and other proprietary information will not otherwise become known. Enforcing a claim that a party disclosed proprietary information in an unauthorized manner or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts are less willing or unwilling to protect trade secrets, and agreement terms that address non-competition are difficult to enforce in many jurisdictions and might not be enforceable in certain cases. Furthermore, even if we successfully maintain the confidentiality of our trade secrets and other proprietary information, competitors may independently develop products or technologies that are substantially equivalent or superior to our own.

If we are unable to maintain the proprietary nature of our technologies, intellectual property, trade secrets and other proprietary information, our competitive position, business, financial condition, and results of operations could be harmed.

We may need to defend ourselves against claims that we infringe, have misappropriated or otherwise violate the intellectual property rights of others, which may be time-consuming and would cause us to incur substantial costs. Third-party claims that we are infringing on intellectual property, whether successful or not, could subject us to costly and time-consuming litigation or expensive licenses, and our business could be adversely affected.

Companies, organizations, or individuals, including our competitors, and suppliers may hold or obtain patents, trademarks or other proprietary rights that they may in the future believe are infringed by our products or services. Although we are not currently subject to any claims related to intellectual property, these companies holding patents, trademarks or other intellectual property rights allegedly relating to our technologies could, in the future, make claims or bring suits alleging infringement, misappropriation or other violations of such rights, or otherwise asserting their rights and seeking licenses or injunctions. If a claim is successfully brought in the future and we or our products are determined to have infringed, misappropriated or otherwise violated a third party’s intellectual property rights, we may be required to do one or more of the following:

• cease selling or using our products that incorporate the challenged intellectual property;

• pay substantial royalty or license fees or other damages (including treble damages and attorneys’ fees if our infringement is determined to be willful);

• obtain a license from the holder of the intellectual property right, which license may not be available on reasonable terms, or at all;

• redesign or reengineer our technology, products or services, which may be costly, time-consuming or impossible; or

• establish and maintain alternative branding for our technology, products or services.

Any of the foregoing could adversely affect our business, prospects, operating results and financial condition. In addition, any litigation or claims, whether or not valid, could harm our reputation, result in substantial costs and divert resources and management attention.

Cyber-attacks or a failure in our information technology and data security infrastructure could adversely affect our business and operations.

We may rely in the future on information technology systems in connection with various aspects of the operation of our business. Our business may depend on the integrity of such information technology systems, which are inherently susceptible to a number of threats, including, but not limited to, viruses, ransomware, malware, malicious codes, hacking, phishing, denial of service actions, human error, network failures, electronic loss of data and other electronic security breaches. A successful material cyber-attack may result in the loss or compromise of customer, financial or operational data, theft of intellectual property, disruption of billing, collections or normal field service activities, disruption of data analytics and electronic monitoring and control of operational systems, loss of revenue, ransomware payments, remediation costs related to lost, stolen or compromised data, repairs to infrastructure, physical systems or data processing systems, increased cybersecurity protection costs or violation of United States and international privacy laws, which may result in litigation. Any of these occurrences could harm our reputation or have a material adverse effect on our business, financial condition, results of operation and prospects. We intend to adopt measures to mitigate potential risks associated with information technology disruptions and cybersecurity threats; however, there is no assurance that these measures will prevent cyber-attacks or security breaches. Although we intend to periodically assess these risks, implement controls and perform business continuity and disaster recovery planning, we cannot be sure that interruptions with material adverse effects will not occur.

A number of foreign countries do not protect intellectual property rights to the same extent as the United States. Therefore, our intellectual property rights may not be as strong or as easily enforced outside of the United States and efforts to protect against the infringement, misappropriation or unauthorized use of our intellectual property rights, technology and other proprietary rights may be difficult and costly outside of the United States. Furthermore, legal standards relating to the intellectual property rights are uncertain and any changes in, or unexpected interpretations of, intellectual property laws may compromise our ability to enforce our patent rights, trade secrets and other intellectual property rights.

Patent, trademark, trade secret and other intellectual property laws are geographical in scope and vary throughout the world. Some foreign countries do not protect intellectual property rights to the same extent as do the laws of the United States. In addition, trade secrets and know-how can be difficult to protect and some courts inside and outside the United States are less willing or unwilling to protect trade secrets and know-how. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them from using that technology or information to compete with us, and our competitive position would be materially and adversely harmed. Further, even if we engaged local counsel in key foreign jurisdictions, policing the unauthorized use of our intellectual property in foreign jurisdictions may be difficult or impossible. Therefore, our intellectual property rights may not be as strong or as easily enforced outside of the United States, and efforts to protect against the infringement, misappropriation or unauthorized use of our intellectual property rights, technology and other proprietary rights may be difficult and costly outside of the United States. Furthermore, legal standards relating to the validity, enforceability and scope of protection of intellectual property rights are uncertain, and any changes in, or unexpected interpretations of, intellectual property laws may compromise our ability to enforce our patent rights, trade secrets and other intellectual property rights.

We rely on licenses to use the intellectual property rights of third parties, which are incorporated into our products, services and offerings.

We rely, and expect to continue to rely on, certain services and intellectual property that we license from third parties for use in our operations. We cannot be certain that our licensors are not infringing upon the intellectual property rights of others or that our suppliers and licensors have sufficient rights to the third-party technology used in our business in all jurisdictions in which we may operate. Disputes with licensors over uses or terms could result in the payment of additional royalties or penalties by us, cancellation or non-renewal of the underlying license or litigation. In the event that we cannot renew and/or expand existing licenses, we may be required to discontinue or limit our use of the operations, products, or offerings that include or incorporate the licensed intellectual property. Any such discontinuation or limitation could have a material and adverse impact on our business, financial condition and results of operation.

Risks Related to Being a Public Company

The market price of shares of our common stock may be volatile or may decline regardless of our operating performance. You may lose some or all of your investment.

The trading price of our common stock following the Business Combination is likely to be volatile. The stock market recently has experienced extreme volatility. This volatility often has been unrelated or disproportionate to the operating performance of particular companies. You may not be able to resell your shares at an attractive price due to a number of factors such as those listed in “— Risks Related to Montana’s Operations, Technology and Financial Condition” and the following:

• the uncertainty resulting from the COVID-19 pandemic, the invasion of Ukraine by Russia and resulting sanctions, and other events (such as terrorist attacks, geopolitical unrest, natural disasters or a significant outbreak of other infectious diseases);

• our operating and financial performance and prospects;

• our quarterly or annual earnings or those of other companies in our industry compared to market expectations;

• conditions that impact demand for our products and/or services;

• future announcements concerning our business, our clients’ businesses or our competitors’ businesses;

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

• the market’s reaction to our reduced disclosure and other requirements as a result of being an “emerging growth company” under the Jumpstart Our Business Startups Act (the “JOBS Act”);

• the size of our public float;

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

• market and industry perception of our success, or lack thereof, in pursuing our growth strategy;

• strategic actions by us or our competitors, such as acquisitions or restructurings;

• changes in laws or regulations, or changes in the implementation of regulations by regulatory bodies, which adversely affect our industry or us;

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

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

• changes in senior management or key personnel;

• issuances, exchanges or sales, or expected issuances, exchanges or sales of our capital stock;

• changes in our dividend policy;

• adverse resolution of new or pending litigation against us; and

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

These broad market and industry factors may materially reduce the market price of our common stock, regardless of our operating performance. In addition, price volatility may be greater if the public float and trading volume of our common stock is low. As a result, you may suffer a loss on your investment.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If we were involved in securities litigation, it could have a substantial cost and divert resources and the attention of management from our business regardless of the outcome of such litigation.

Since the redemption by XPDB Public Stockholders, there may be increased volatility in the trading of XPDB Common Stock due to a lower public float.

The XPDB Public Stockholders elected to redeem 18,141,822 Public Shares in connection with the implementation of the Extension. Upon completion of such redemption, 10,608,178 Public Shares remained issued and outstanding. As a result, there is a lower public float of the XPDB Class A Common Stock, which may cause further volatility in the price of our securities and adversely impact our ability to secure financing following the Closing. Holders will have redemption rights in connection with the Special Meeting to vote on the Business Combination, and consequently, the public float may be further reduced if additional XPDB Public Stockholders redeem their shares.

We do not intend to pay dividends on our common stock for the foreseeable future.

We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. As a result, we do not anticipate declaring or paying any cash dividends on our common stock in the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of our board of directors and will depend on, among other things, our business prospects, results of operations, financial condition, cash requirements and availability, certain restrictions related to our indebtedness, industry trends and other factors that our board of directors may deem relevant. Any such decision will also be subject to compliance with contractual restrictions and covenants in the agreements governing our current and future indebtedness. In addition, we may incur additional indebtedness, the terms of which may further restrict or prevent us from paying dividends on our common stock. As a result, you may have to sell some or all of your common stock after price appreciation in order to generate cash flow from your investment, which you may not be able to do. Our inability or decision not to pay dividends, particularly when others in our industry have elected to do so, could also adversely affect the market price of our common stock.

If securities or industry analysts do not publish research or reports about our business or publish negative reports, the market price of our common stock could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We may be unable or slow to attract research coverage and if one or more analysts cease coverage of us, the price and trading volume of our securities would likely be negatively impacted. If any of the analysts that may cover us change their recommendation regarding our securities adversely, or provide more favorable relative recommendations about our competitors, the price of our securities would likely decline. If any analyst that may cover us ceases covering us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which could cause the price or trading volume of our securities to decline. Moreover, if one or more of the analysts who cover us downgrades our common stock or if our reporting results do not meet their expectations, the market price of our common stock could decline.

Our ability to timely raise capital in the future may be limited, or may be unavailable on acceptable terms, if at all. Our failure to raise capital when needed could harm our business, operating results and financial condition. Debt issued to raise additional capital may reduce the value of our common stock.

We have funded our operations since inception primarily through the continued financial support from our shareholders and other related parties. We cannot be certain when or if our operations will generate sufficient cash to fund our ongoing operations or the growth of our business.

We intend to continue to make investments to support our business and may require additional funds. Additional financing may not be available on favorable terms, if at all. If adequate funds are not available on acceptable terms, we may be unable to invest in future growth opportunities, which could harm our business, operating results and financial condition. If we incur debt, the terms of such debt, including the accrual of interest at fixed or variable interest rates, could restrict our operations, including our ability to pay dividends on our common stock. Moreover, as a result of widespread inflation in the global economy, certain governmental authorities responsible for administering monetary policy have recently increased, and may continue to increase, applicable central bank interest rates, which could increase the costs required to obtain debt financing in the future or refinance any such future indebtedness Furthermore, if we incur debt, the debt holders could have rights senior to holders of common stock to make claims on our assets. As a result, our stockholders bear the risk of future issuances of debt securities reducing the value of our common stock.

Our issuance of additional shares of common stock or convertible securities could make it difficult for another company to acquire us, may dilute your ownership of us and could adversely affect our stock price.

In connection with the proposed Business Combination, we intend to file a registration statement with the SEC on Form S-8 providing for the registration of shares of our common stock reserved for issuance pursuant to Montana Options and under the Incentive Plan and the ESPP. The Incentive Plan and ESPP each will provide for automatic increases in the shares reserved for grant or issuance under the applicable plan which could result in additional dilution to our stockholders. Subject to the satisfaction of vesting conditions and the expiration of any applicable lockup restrictions, shares registered under the registration statement on Form S-8 will generally be available for resale immediately in the public market without restriction. From time to time in the future, we may also issue additional shares of our common stock or securities convertible into common stock pursuant to a variety of transactions, including acquisitions. We may also execute or have executed agreements which allow certain third parties the right to purchase additional shares of our common stock or securities convertible into common stock. The issuance by us of additional shares of our common stock or securities convertible into our common stock would dilute your ownership of us and the sale of a significant amount of such shares in the public market could adversely affect prevailing market prices of our common stock.

In the future, we expect to obtain financing or to further increase our capital resources by issuing additional shares of our capital stock or offering debt or other equity securities, including senior or subordinated notes, debt securities convertible into equity, or shares of preferred stock. Issuing additional shares of our capital stock, other equity securities, or securities convertible into equity may dilute the economic and voting rights of our existing stockholders, reduce the market price of our common stock, or both. Debt 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. Preferred stock, if issued, could have a preference with respect to liquidating distributions or a preference with respect to dividend payments that could limit our ability to pay dividends to the holders of our common stock. Our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, which may adversely affect the amount, timing or nature of our future offerings. As a result, holders of our common stock bear the risk that our future offerings may reduce the market price of our common stock and dilute their percentage ownership. See the section entitled “Description of Capital Stock of the Post-Combination Company.”

Future sales, or the perception of future sales, of our common stock by us or our existing stockholders in the public market following the Closing could cause the market price for our common stock to decline.

The sale of substantial amounts of shares of our common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

Upon consummation of the Business Combination, in the Assuming Minimum Redemption Scenario, we will have a total of 55,741,006 shares of common stock outstanding, consisting of (i) 37,945,328 shares issued to holders of Montana Class A Common Units and Montana Class B Common Units, (ii) 10,608,178 shares held by XPDB Public Stockholders, (iii) 7,097,500 shares held by the Sponsor and our Anchor Investors (including up to 1,380,736 shares subject to vesting and earnout requirements pursuant to the Sponsor Support Agreement) and (iv) 90,000 shares held by the independent directors of XPDB. Montana Equityholders (other than holders of Montana Warrants) will also have the opportunity to receive up to 20.0 million Earnout Shares. All shares issued as Merger Consideration in the Business Combination will be freely tradable without registration under the Securities Act and without restriction by persons other than our “affiliates” (as defined under Rule 144 of the Securities Act, referred to herein as “Rule 144”), including our directors, executive officers and other affiliates.

In connection with the Closing, Sponsor, XPDB’s independent directors and certain Montana Equityholders will each enter into Lock-Up Agreements with the Post-Combination Company, pursuant to which they will be subject to certain restrictions on transfer with respect to the shares of common stock issued as part of the Merger Consideration beginning at Closing and ending on the date that is six months after the completion of the Business Combination and with respect to the Private Placement Warrants, thirty calendar days after the completion of the Business Combination. See the section entitled “Other Agreements — Lock-Up Agreements” for a description of the Lock-Up Agreements.

Upon the expiration or waiver of the lock-ups described above, shares held by certain of our stockholders will be eligible for resale, subject to, in the case of certain stockholders, volume, manner of sale and other limitations under Rule 144.

Table of Contents

In addition, pursuant to the Registration Rights Agreement, certain stockholders will have the right, subject to certain conditions, to require us to register the sale of their shares of our common stock under the Securities Act. By exercising their registration rights and selling a large number of shares, these stockholders could cause the prevailing market price of our common stock to decline. Following completion of the Business Combination, the shares covered by registration rights would represent approximately % and % of our outstanding common stock in the Assuming No Redemptions Scenario and Assuming Maximum Contractual Redemptions Scenario, respectively. See the section entitled “Other Agreements — Registration Rights Agreement” for a description of these registration rights.

As shares vest pursuant to the Sponsor Support Agreement, Earnout Shares are earned, restrictions on resale end or if these stockholders exercise their registration rights, the market price of shares of our common stock could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our shares of common stock or other securities.

In addition, the shares of our common stock issuable pursuant to the Montana Options and reserved for future issuance under the Incentive Plan and the ESPP will become eligible for sale in the public market once those shares are issued, subject to provisions relating to various vesting agreements, lock-up agreements and, in some cases, limitations on volume and manner of sale applicable to affiliates under Rule 144, as applicable. The number of shares to be reserved for future issuance under the Incentive Plan is expected to equal , or shares of our common stock, in the Assuming Minimum Redemptions Scenario, Assuming Mid-Point Redemptions Scenario or Assuming Maximum Contractual Redemptions Scenario, respectively. The number of shares to be reserved for future issuance under the ESPP is expected to equal , or shares of our common stock, in the Assuming Minimum Redemptions Scenario, Assuming Mid-Point Redemptions Scenario or Assuming Maximum Contractual Redemptions Scenario, respectively. We expect to file one or more registration statements on Form S-8 under the Securities Act to register shares of our common stock or securities issuable pursuant to the Montana Options, the Incentive Plan and the ESPP. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market.

The requirements of being a public company, including compliance with the reporting requirements of the Exchange Act, the requirements of the Sarbanes-Oxley Act and the requirements of the Nasdaq, may strain our resources, increase our costs and require additional attention of management, and we may be unable to comply with these requirements in a timely or cost-effective manner.

As a public company, we will be subject to laws, regulations and requirements, certain corporate governance provisions of the Sarbanes-Oxley Act, related regulations of the SEC and the requirements of the Nasdaq, which we were not required to comply with as a private company. As a newly public company as a result of the Business Combination, complying with these statutes, regulations and requirements will occupy a significant amount of time of our board of directors and management and significantly increases our costs and expenses. For example, we will have to institute a more comprehensive compliance function, comply with rules promulgated by the Nasdaq, prepare and distribute periodic public reports in compliance with our obligations under the federal securities laws, and establish new internal policies, such as those relating to insider trading. We will also have to retain and rely on outside counsel and accountants to a greater degree in these activities. In addition, being subject to these rules and regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as executive officer.

We are an “emerging growth company.” The reduced public company reporting requirements applicable to emerging growth companies may make our common stock less attractive to investors.

We qualify as an “emerging growth company,” as defined in the JOBS Act. While we remain an emerging growth company, we are permitted and plan to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These provisions include: (1) presenting only two years of audited financial statements, (2) presenting only two years of related selected financial data and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure, (3) an

Table of Contents

exemption from compliance with the auditor attestation requirement in the assessment of our internal control over financial reporting pursuant to Section 404 of Sarbanes-Oxley, (4) 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, (5) reduced disclosure obligations regarding executive compensation arrangements in our periodic reports, registration statements, and proxy statements, and (6) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, the information we provide will be different than the information that is available with respect to other public companies that are not emerging growth companies. Additionally, management has elected to present two years of audited financial statements and selected financial data.

We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock. The market price of our common stock may be more volatile.

We will remain an emerging growth company until the earliest of: (1) December 31, 2026, (2) the first fiscal year after our annual gross revenue exceed $1.235 billion, (3) the date on which we have, during the immediately preceding three-year period, issued more than $1.0 billion in non-convertible debt securities, and (4) the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeds $700 million as of the end of the second quarter of that fiscal year.

Our management has limited experience in operating a public company.

Our executive officers have limited experience in the management of a publicly traded company. Our management team may not successfully or effectively manage its transition to a public company that will be subject to significant regulatory oversight and reporting obligations under federal securities laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less time being devoted to the management and growth of the Post-Combination Company. We may not have adequate personnel with the appropriate level of knowledge, experience, and training in the accounting policies, practices or internal controls over financial reporting required of public companies in the United States. The development and implementation of the standards and controls necessary for the Post-Combination Company to achieve the level of accounting standards required of a public company in the United States may require costs greater than expected. It is possible that the Post-Combination Company will be required to expand its employee base and hire additional employees to support its operations as a public company which will increase its operating costs in future periods.

Changes to, or changes to interpretations of, the U.S. federal, state, local or other jurisdictional tax laws could have a material adverse effect on our business, financial condition and results of operations.

All statements contained herein concerning U.S. federal income tax (or other tax) consequences are based on existing law and interpretations thereof. The tax regimes to which we are subject or under which we operate, including income and non-income taxes, are unsettled and may be subject to significant change. While some of these changes could be beneficial, others could negatively affect our after-tax returns. Accordingly, no assurance can be given that the currently anticipated tax treatment will not be modified by legislative, judicial or administrative changes, possibly with retroactive effect. In addition, no assurance can be given that any tax authority or court will agree with any particular interpretation of the relevant laws.

State, local or other jurisdictions could impose, levy or otherwise enforce tax laws against us. Tax laws and regulations at the state and local levels frequently change, especially in relation to the interpretation of existing tax laws for new and emerging industries, and we cannot always reasonably predict the impact from, or the ultimate cost of compliance with, current or future taxes, which could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to the Business Combination

XPDB stockholders will have a reduced ownership and voting interest after the Business Combination and will exercise less influence over management.

Upon the issuance of the shares to Montana Equityholders, current XPDB stockholders’ percentage ownership will be diluted. In the Assuming Minimum Redemptions Scenario and excluding any shares issuable pursuant to XPDB’s outstanding warrants, options to purchase shares of Class A Common Stock or shares to be reserved for issuance under the Incentive Plan or ESPP, current XPDB stockholders’ percentage ownership in the Post-Combination Company following the issuance of shares to Montana Equityholders would be approximately 19.0%. Additionally, of the expected members of the Post-Combination Company Board after the completion of the Business Combination, only will be current directors of XPDB and will be current directors of Montana. The percentage of the Post-Combination Company’s common stock that will be owned by current XPDB stockholders as a group will vary based on the number of Public Shares for which the holders thereof request redemption in connection with the Business Combination. To illustrate the potential ownership percentages of current XPDB stockholders (including the Sponsor and directors of XPDB), under different redemption levels, based on the number of issued and outstanding shares of XPDB Common Stock and units of Montana on June 30, 2023, after taking into account the June Redemptions, and based on the Merger Consideration, current XPDB stockholders as a group, will own (1) in the Assuming Mid-Point Redemption Scenario, approximately 17.2% of the Post-Combination Company’s common stock expected to be outstanding immediately after the Business Combination or (2) in the Assuming Maximum Contractual Redemptions, approximately 15.1% of the Post-Combination Company’s common stock expected to be outstanding immediately after the Business Combination (in each case, excluding any shares issuable pursuant to XPDB’s outstanding warrants, options to purchase shares of Class A Common Stock or shares to be reserved for issuance under the Incentive Plan or ESPP). Because of this, current XPDB stockholders, as a group, will have less influence on the board of directors, management and policies of the Post-Combination Company than they now have on the board of directors, management and policies of XPDB.

The market price of shares of the Post-Combination Company’s common stock after the Business Combination may be affected by factors different from those currently affecting the prices of shares of XPDB Class A Common Stock.

Upon completion of the Business Combination, holders of Montana Common Units and Montana Preferred Units will become holders of shares of the Post-Combination Company’s common stock. Prior to the Business Combination, XPDB has had limited operations. Upon completion of the Business Combination, the Post-Combination Company’s results of operations will depend upon the performance of Montana’s businesses, which are affected by factors that are different from those currently affecting the results of operations of XPDB.

XPDB has not obtained an opinion from an independent investment banking firm, and consequently, there is no assurance from an independent source that the Merger Consideration is fair to its stockholders from a financial point of view.

XPDB is not required to, and has not, obtained an opinion from an independent investment banking firm that the Merger Consideration it is paying for Montana is fair to XPDB’s stockholders from a financial point of view. The fair market value of Montana has been determined by the XPDB Board based upon standards generally accepted by the financial community, such as potential sales and the price for which comparable businesses or assets have been valued. The XPDB Board believes because of the financial skills and background of its directors, it was qualified to conclude that the Business Combination was fair from a financial perspective to its stockholders and that Montana’s fair market value was at least 80% of the assets held in the Trust Account (excluding the Deferred Discount and taxes payable on interest earned on the Trust Account) at the time of the agreement to enter into the Business Combination. XPDB’s stockholders will be relying on the judgment of its board of directors with respect to such matters.

If the Business Combination’s benefits do not meet the expectations of financial analysts, the market price of our common stock may decline.

The market price of our common stock may decline as a result of the Business Combination if we do 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 our financial results is not consistent with the expectations of financial analysts. Accordingly, holders of our common stock following the consummation of the Business Combination may experience

Table of Contents

a loss as a result of a decline in the market price of such common stock. In addition, a decline in the market price of our common stock following the consummation of the Business Combination could adversely affect our ability to issue additional securities and to obtain additional financing in the future.

There can be no assurance that the Post-Combination Company’s common stock will be approved for listing on the Nasdaq or that the Post-Combination Company will be able to comply with the continued listing standards of the Nasdaq.

In connection with the Closing, we intend to list the Post-Combination Company’s common stock and Warrants on the Nasdaq under the symbols “AIRJ” and “AIRJW,” respectively. The Post-Combination Company’s continued eligibility for listing may depend on the number of our shares that are converted. If, after the Business Combination, the Nasdaq delists the Post-Combination Company’s shares from trading on its exchange for failure to meet the listing standards, the Post-Combination Company and its stockholders could face significant material adverse consequences including:

• a limited availability of market quotations for the Post-Combination Company’s securities;

• reduced liquidity for the Post-Combination Company’s securities;

• a determination that the Post-Combination Company’s common stock is a “penny stock” which will require brokers trading in the Post-Combination Company’s common stock to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for shares of the Post-Combination Company’s common stock;

• a limited amount of analyst coverage; and

• a decreased ability to issue additional securities or obtain additional financing in the future.

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

The Merger Agreement is subject to a number of conditions which must be fulfilled in order to complete the Business Combination. Those conditions include: approval of the proposals required to effect the Business Combination by XPDB stockholders, as well as receipt of certain requisite regulatory approvals, absence of orders prohibiting completion of the Business Combination, effectiveness of the registration statement of which this proxy statement/prospectus is a part, approval of the shares of Class A Common Stock to be issued to XPDB stockholders for listing on the Nasdaq, the accuracy of the representations and warranties by both parties (subject to the materiality standards set forth in the Merger Agreement) and the performance by both parties of their covenants and agreements. These conditions to the Closing 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 Merger Agreement at any time, before or after stockholder approval, or XPDB or Montana may elect to terminate the Merger Agreement in certain other circumstances. See the section entitled “The Merger Agreement — Termination.”

The parties to the Merger Agreement may amend the terms of the Merger Agreement or waive one or more of the conditions to Closing, and the exercise of discretion by our directors and officers in agreeing to changes to the terms of or waivers of closing conditions in the Merger Agreement may result in a conflict of interest when determining whether such changes to the terms of the Merger Agreement or waivers of conditions are appropriate and in the best interests of our stockholders.

In the period leading up to the Closing, other events may occur that, pursuant to the Merger Agreement, would require us to agree to amend the Merger Agreement, to consent to certain actions or to waive certain closing conditions or other rights that we are entitled to under the Merger Agreement. Such events could arise because of changes in the course of Montana’s business, a request by Montana to undertake actions that would otherwise be prohibited by the terms of the Merger Agreement or the occurrence of other events that would have a material adverse effect on Montana’s business and would entitle us to terminate the Merger Agreement. In any of such circumstances, it would be in our discretion, acting through our board of directors, to grant our consent or waive our rights. The existence of the financial and personal interests of the directors and officers described elsewhere in this proxy statement may result in a conflict of interest on the part of one or more of the directors or officers between what he or she may believe is best for XPDB and our stockholders and what he or she may believe is best for himself or herself or his or her affiliates in determining whether or not to take the requested action.

Table of Contents

For example, it is a condition to XPDB’s obligation to close the Business Combination that Montana’s representations and warranties be true and correct as of the Closing in all respects subject to the applicable materiality standards as set forth in the Merger Agreement. However, if the XPDB Board determines that any such breach is not material to the business of Montana, then the XPDB Board may elect to waive that condition and close the Business Combination. The parties will not waive the condition that XPDB’s stockholders approve the Business Combination.

While certain changes could be made without further stockholder approval, if there is a change to the terms of the Business Combination that would have a material impact on the stockholders, we will be required to circulate a new or amended proxy statement or supplement thereto and resolicit the vote of our stockholders with respect to the Business Combination Proposal.

Termination of the Merger Agreement could negatively impact Montana and XPDB.

If the Business Combination is not completed for any reason, including as a result of Montana Equityholders declining to adopt the Merger Agreement or XPDB stockholders declining to approve the proposals required to effect the Business Combination, the ongoing businesses of Montana and XPDB may be adversely impacted and, without realizing any of the anticipated benefits of completing the Business Combination, Montana and XPDB would be subject to a number of risks, including the following:

• Montana or XPDB may experience negative reactions from the financial markets, including negative impacts on its stock price (including to the extent that the current market price reflects a market assumption that the Business Combination will be completed);

• Montana may experience negative reactions from its customers, vendors and employees;

• Montana and XPDB will have incurred substantial expenses and will be required to pay certain costs relating to the Business Combination, whether or not the Business Combination is completed; and

• since the Merger Agreement restricts the conduct of Montana’s and XPDB’s businesses prior to completion of the Business Combination, each of Montana and XPDB may not have been able to take certain actions during the pendency of the Business Combination that would have benefitted it as an independent company, and the opportunity to take such actions may no longer be available (see the section of this proxy statement/prospectus entitled “The Merger Agreement — Covenants and Agreements” for a description of the restrictive covenants applicable to Montana and XPDB).

If the Merger Agreement is terminated and Montana’s board of directors seeks another merger or business combination, Montana Equityholders cannot be certain that Montana will be able to find a party willing to offer equivalent or more attractive consideration than the consideration XPDB has agreed to provide in the Business Combination or that such other merger or business combination is completed. If the Merger Agreement is terminated and the XPDB Board seeks another merger or business combination, XPDB stockholders cannot be certain that XPDB will be able to find another acquisition target that would constitute a business combination or that such other merger or business combination will be completed before the end of the Completion Window. See the section entitled “The Merger Agreement — Termination.”

Montana will be subject to business uncertainties and contractual restrictions while the Business Combination is pending.

Uncertainty about the effect of the Business Combination on employees and customers may have an adverse effect on Montana and consequently on XPDB. These uncertainties may impair Montana’s ability to attract, retain and motivate key personnel until the Business Combination is completed and could cause customers and others that deal with Montana to seek to change existing business relationships with Montana. Retention of certain employees may be challenging during the pendency of the Business Combination as certain employees may experience uncertainty about their future roles. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the business, our business following the Business Combination could be negatively impacted. In addition, the Merger Agreement restricts Montana from making certain expenditures and taking other specified actions without the consent of XPDB until the Business

Table of Contents

Combination occurs. These restrictions may prevent Montana from pursuing attractive business opportunities that may arise prior to the completion of the Business Combination. See the section entitled “The Merger Agreement — Covenants and Agreements.”

XPDB directors and officers may have interests in the Business Combination different from the interests of XPDB stockholders.

Executive officers of XPDB negotiated the terms of the Merger Agreement with their counterparts at Montana, and the XPDB Board determined that entering into the Merger Agreement was in the best interests of XPDB and its stockholders, declared the Merger Agreement advisable and recommended that XPDB stockholders approve the proposals required to effect the Business Combination. In considering these facts and the other information contained in this proxy statement/prospectus, you should be aware that XPDB’s executive officers and directors may have financial interests in the Business Combination that may be different from, or in addition to, the interests of XPDB stockholders. Specifically, the 7,187,500 Founder Shares held by the Initial Stockholders, which were acquired for an aggregate purchase price of $25,000 prior to the completion of the XPDB IPO, and the 8,900,000 Private Placement Warrants the Sponsor purchased from XPDB for an aggregate purchase price of approximately $8,900,000 (or $1.00 per warrant) concurrently with the closing of the XPDB IPO, will expire worthless if XPDB does not consummate a business combination within the Completion Window. The XPDB Board was aware of and considered these interests, among other matters, in reaching the determination to approve the terms of the Business Combination and in recommending to XPDB’s stockholders that they vote to approve the Business Combination. For a detailed discussion of the special interests that XPDB’s directors and executive officers may have in the Business Combination, please see the section entitled “The Business Combination — Interests of the Sponsor and XPDB’s Directors and Executive Officers in the Business Combination.”

Montana directors and officers may have interests in the Business Combination different from the interests of Montana Equityholders.

Executive officers of Montana negotiated the terms of the Merger Agreement with their counterparts at XPDB, and the Montana board of managers determined that entering into the Merger Agreement was in the best interests of Montana and its stockholders. In considering these facts and the other information contained in this proxy statement/prospectus, you should be aware that Montana’s executive officers and directors may have financial interests in the Business Combination that may be different from, or in addition to, the interests of Montana Equityholders. The Montana board of managers was aware of and considered these interests, among other matters, in reaching the determination to approve the terms of the Business Combination.

The Sponsor may have interests in the Business Combination different from the interests of XPDB stockholders.

When considering the XPDB Board’s recommendation that XPDB stockholders vote in favor of the approval of the Business Combination Proposal and the other Proposals described in this proxy statement, stockholders should be aware that the Sponsor has interests in the Business Combination that may be different from, in addition to, or conflict with the interests of our stockholders in general. Certain members of the XPDB Board collectively own 90,000 shares of XPDB Class B Common Stock and the Sponsor holds 7,097,500 shares of XPDB Class B Common Stock, which were acquired for an aggregate purchase price of $25,000 prior to the completion of the XPDB IPO. XPDB has agreed to sell to the Anchor Investors up to 1,078,125 shares of XPDB Class B Common Stock on the date of the initial business combination for an aggregate purchase price of approximately $4,312.51 or approximately $0.004 per share. Our Sponsor has also agreed that in the event of such purchase by the Anchor Investors, our Sponsor will forfeit to us for no consideration a number of shares of XPDB Class B Common Stock equal to the number of shares purchased by the Anchor Investors. The Sponsor holds 8,900,000 Private Placement Warrants purchased from XPDB for an aggregate purchase price of approximately $8,900,000 (or $1.00 per warrant) concurrently with the closing of the XPDB IPO. The XPDB Class B Common Stock and Private Placement Warrants will expire worthless if XPDB does not consummate a business combination within the Completion Window. For a more complete description of these interests, see the section entitled “The Business Combination — Interests of the Sponsor and XPDB’s Directors and Executive Officers in the Business Combination.”

Because Montana will become a publicly traded company through the Business Combination rather than an underwritten initial public offering, the scope of due diligence conducted may be different from that conducted by an underwriter in an underwritten initial public offering.

Montana will effectively become a publicly listed company upon the completion of the Business Combination. The Business Combination and the transactions described in this proxy statement/prospectus differ from an underwritten initial public offering. In a traditional underwritten initial public offering, underwriters typically conduct a certain amount of due diligence on the company being taken public in order to establish a due diligence defense against liability claims under federal securities laws. Because XPDB is already a publicly listed company, an underwriter has not been engaged. The due diligence conducted by management and the XPDB Board may be different than the due diligence undertaken by an underwriter in a traditional initial public offering. The Sponsor may have an inherent conflict of interest because its shares and warrants will be worthless if an initial business combination is not completed with Montana or another company before December 14, 2023 or such further extended date as determined by the XPDB Board in accordance with the Existing Charter. Therefore, there could be a heightened risk of an incorrect valuation of Montana’s business, which could cause potential harm to investors.

The Business Combination will result in changes to the board of directors that may affect our strategy.

If the parties complete the Business Combination and the Director Election Proposal is approved, the composition of the Post-Combination Company Board will change from the current boards of directors of XPDB and Montana. The Post-Combination Company Board will be divided into three classes and will consist of the directors elected pursuant to the Director Election Proposal, each of which will serve an initial term ending in either 2024, 2025 or 2026, and thereafter will serve a three-year term. This new composition of the Post-Combination Company Board may affect our business strategy and operating decisions upon the completion of the Business Combination.

The Merger Agreement contains provisions that may discourage other companies from trying to acquire Montana for greater Merger Consideration.

The Merger Agreement contains provisions that prohibit Montana from seeking alternative business combinations during the pendency of the Business Combination. These provisions include a general prohibition on Montana from soliciting or entering into discussions with any third party regarding any acquisition proposal or offers for competing transactions. Montana also has an unqualified obligation to submit the proposal to adopt the Merger Agreement to a vote by its stockholders, even if Montana receives an alternative acquisition proposal that its board of directors believes is superior to the Business Combination, unless the Merger Agreement has been terminated in accordance with its terms. See the section entitled “The Merger Agreement — Termination.”

The Merger Agreement contains provisions that may discourage XPDB from seeking an alternative business combination.

The Merger Agreement contains provisions that prohibit XPDB from seeking alternative business combinations during the pendency of the Business Combination. Further, if XPDB is unable to obtain the requisite approval of its stockholders, either party may terminate the Merger Agreement. See the section entitled “The Merger Agreement — Termination.”

The unaudited pro forma condensed combined financial information included in this proxy statement/prospectus is preliminary and the actual financial condition and results of operations after the Business Combination may differ materially.

The unaudited pro forma financial information included in this proxy statement/prospectus is presented for illustrative purposes only and is not necessarily indicative of what our actual financial position or results of operations would have been had the Business Combination been completed on the date(s) indicated. The preparation of the pro forma financial information is based upon available information and certain assumptions and estimates that XPDB and Montana currently believe are reasonable. The unaudited pro forma financial information reflects adjustments, which are based upon preliminary estimates, among other things, to allocate the purchase price to Montana’s net assets. The purchase price allocation reflected in this proxy statement/prospectus is preliminary, and the final allocation of the purchase price will be based upon the actual purchase price and the fair value of the assets and liabilities of Montana as of the date of the completion of the Business Combination. In addition, following the completion of the Business Combination, there

Table of Contents

may be further refinements of the purchase price allocation as additional information becomes available. Accordingly, the final purchase accounting adjustments may differ materially from the pro forma adjustments reflected in this proxy statement/prospectus. See the section entitled “Unaudited Pro Forma Condensed Combined Financial Information.”

XPDB and Montana will incur transaction costs in connection with the Business Combination.

Each of XPDB and Montana has incurred and expects that it will incur significant, non-recurring costs in connection with consummating the Business Combination. XPDB and Montana may also incur additional costs to retain key employees. XPDB and Montana 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. XPDB and Montana estimate that they will incur approximately $20.0 million in aggregate transaction costs, inclusive of approximately $6 million in form of a Deferred Discount. Some of these costs are payable regardless of whether the Business Combination is completed. See the section entitled “The Business Combination — Terms of the Business Combination.”

XPDB’s stockholders will have their rights as stockholders governed by the Post-Combination Company’s organizational documents.

As a result of the completion of the Business Combination, holders of shares of XPDB Common Stock will become holders of shares of the Post-Combination Company’s common stock, which are expected to be governed by the Post-Combination Company’s organizational documents. As a result, there will be differences between the rights currently enjoyed by XPDB stockholders and the rights that XPDB stockholders who become stockholders of the Post-Combination Company will have as stockholders of the Post-Combination Company. See the section entitled “Comparison of Stockholders’ Rights.”

The Sponsor has agreed to vote in favor of each of the Proposals presented at the Special Meeting, regardless of how XPDB Public Stockholders vote.

Pursuant to the Sponsor Support Agreement, the Sponsor has agreed to vote its Founder Shares and any Public Shares it holds in favor of each of the Proposals presented at the Special Meeting, regardless of how XPDB Public Stockholders vote. Accordingly, given Sponsor’s ownership of approximately 40% of the XPDB Common Stock as of June 30, 2023, the agreement by the Sponsor to vote in favor of the each of the Proposals presented at the Special Meeting will increase the likelihood that XPDB will receive the requisite stockholder approval for the Business Combination and the transactions contemplated thereby. In addition to our Initial Stockholders’ Founder Shares, we would need 1,710,340, or 16.12%, of the 10,608,178 Public Shares outstanding as of June 30, 2023 to be voted in favor of each of the Proposals in order for them to be approved (assuming all issued and outstanding shares are voted). See the section entitled “Other Agreements — Sponsor Support Agreement.”

XPDB’s and Montana’s ability to consummate the Business Combination, and the operations of the Post-Combination Company following the Business Combination, may be materially adversely affected by the recent coronavirus (COVID-19) pandemic.

The COVID-19 pandemic has resulted, and other infectious diseases could result, in a widespread health crisis that has and could continue to adversely affect the economies and financial markets worldwide, which may delay or prevent the consummation of the Business Combination, and the business of Montana or the Post-Combination Company following the Business Combination could be materially and adversely affected. The extent of such impact will depend on future developments, which are highly uncertain and cannot be predicted.

The parties will be required to consummate the Business Combination even if Montana, its business, financial condition and results of operations are materially affected by COVID-19. The disruptions posed by COVID-19 have continued, and other matters of global concern may continue, for an extensive period of time, and if Montana is unable to recover from business disruptions due to COVID-19 or other matters of global concern on a timely basis, Montana’s ability to consummate the Business Combination and the Post-Combination Company’s financial condition and results of operations following the Business Combination may be materially adversely affected. Each of Montana and the Post-Combination Company may also incur additional costs due to delays caused by COVID-19, which could adversely affect the Post-Combination Company’s financial condition and results of operations.

BofA, one of the underwriters in the XPDB IPO, along with Barclays, was to be compensated, in part, on a deferred basis for already-rendered underwriting services in connection with the XPDB IPO, yet it waived such compensation without any consideration from XPDB and, effective as of June 20, 2023, resigned and withdrew from its role in the Business Combination. As a result, BofA disclaims any responsibility for this proxy statement/prospectus and will not be associated with the disclosure or underlying business analysis related to the Business Combination, which could result in an increased number of XPDB stockholders voting against the Business Combination or seeking to redeem their shares for cash.

As underwriters in the XPDB IPO, BofA and Barclays were entitled to a Deferred Discount of $0.35 per share, or $10,062,500 in the aggregate, payable to the underwriters from the amounts held in the Trust Account solely in the event that XPDB completes a Business Combination, subject to the terms of the Underwriting Agreement. On June 20, 2023, BofA formally notified XPDB in writing that it had resigned and withdrew from its role in the Business Combination and thereby waived its entitlement to its portion of the Deferred Discount. Barclays has not resigned from its role in the Business Combination, but has agreed that its $6 million capital markets advisory fee is creditable against its portion of the Deferred Discount. Investors should be aware that a fee waiver for services already rendered is unusual and some investors may find the Business Combination less attractive as a result. This may make it more difficult for XPDB to consummate the Business Combination. As a result of its resignation, BofA claims no role in the Business Combination, disclaims any responsibility for this proxy statement/prospectus and will not be associated with the disclosure or underlying business analysis related to the Business Combination. BofA had no role in the identification or evaluation of business combination targets, and BofA was not involved in the preparation of any disclosure included in this proxy statement/prospectus or any analysis underlying disclosure included in this proxy statement/prospectus. Further, BofA has not assisted in the preparation or review of any materials for XPDB in connection with the Business Combination and did not participate in any other aspect of the Business Combination. You should not put any reliance on the fact that BofA was previously involved in the XPDB IPO. It is possible that such resignation may adversely affect market perception of the Business Combination generally. If market perception of the Business Combination is negatively impacted, an increased number of XPDB stockholders may vote against the Business Combination or seek to redeem their shares for cash.

Risks Related to Ownership of Class A Common Stock Following the Business Combination

Subsequent to the consummation of the Business Combination, the Post-Combination Company may be required to take write-downs or write-offs, or the Post-Combination Company may be subject to restructuring, impairment or other charges that could have a significant negative effect on the Post-Combination Company’s financial condition, results of operations and the price of the Post-Combination Company’s securities, which could cause you to lose some or all of your investment.

Although XPDB has conducted due diligence on Montana, this diligence may not surface all material issues that may be present with Montana’s business. Factors outside of XPDB’s and outside of Montana’s control may, at any time, arise. As a result of these factors, the Post-Combination Company may be forced to later write-down or write-off assets, restructure its operations, or incur impairment or other charges that could result in the Post-Combination Company reporting losses. Even if XPDB’s due diligence successfully identified certain risks, unexpected risks may arise, and previously known risks may materialize in a manner not consistent with our preliminary risk analysis. Even though these charges may be non-cash items and therefore not have an immediate impact on the Post-Combination Company’s liquidity, the fact that the Post-Combination Company reports charges of this nature could contribute to negative market perceptions about the Post-Combination Company or its securities. In addition, charges of this nature may cause the Post-Combination Company to be unable to obtain future financing on favorable terms or at all.

The Post-Combination Company will have a dual class stock structure that will have the effect of concentrating voting control with the holders of Class B Common Stock. The Class B Common Stock will have multiple votes per share, and this ownership will limit or preclude your ability to influence corporate matters, including the election of directors, amendments of the Post-Combination Company’s organizational documents, and any merger, consolidation, sale of all or substantially all of the Post-Combination Company’s assets, or other major corporate transactions requiring stockholder approval, and that may adversely affect the trading price of Class A Common Stock.

The Post-Combination Company will have a dual class stock structure in which shares of Class A Common Stock will each have one vote per share and shares of Class B Common Stock will have a number of votes per share necessary such that the Montana Equityholders collectively would own at the Closing at least 80% of the voting power of all classes of stock of the Post-Combination Company entitled to vote; provided, however, that the number of votes per share shall be at least one vote per share. This concentrated control may limit or preclude your ability to influence corporate matters for the foreseeable future, including the election of directors, amendments of our organizational documents and any merger, consolidation, sale of all or substantially all of our assets or other major corporate transactions requiring stockholder approval. In addition, this concentrated control may prevent or discourage unsolicited acquisition proposals or offers for our capital stock that you may feel are in your best interest as one of our stockholders. As a result, such concentrated control may adversely affect the market price of our Class A Common Stock.

Anti-takeover provisions in our governing documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.

The Proposed Charter, the Amended and Restated Bylaws and Delaware law contain or will contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by our board of directors. Among other things, the Proposed Charter and/or the Amended and Restated Bylaws will include the following provisions:

• a dual class stock structure in which shares of Class A Common Stock will each have one vote per share and shares of Class B Common Stock will have a number of votes per share necessary such that the Montana Equityholders collectively would own at the Closing at least 80% of the voting power of all classes of stock of the Post-Combination Company entitled to vote; provided, however, that the number of votes per share shall be at least one vote per share;

• a staggered board, which means that our board of directors is classified into three classes of directors with staggered three-year terms and directors are only able to be removed from office for cause;

• limitations on convening special stockholder meetings, which could make it difficult for our stockholders to adopt desired governance changes;

• a prohibition on stockholder action by written consent, which means that our stockholders will only be able to take action at a meeting of stockholders and will not be able to take action by written consent for any matter;

• a forum selection clause, which means certain litigation against us can only be brought in Delaware;

• the authorization of undesignated preferred stock, the terms of which may be established and shares of which may be issued without further action by our stockholders; and

• advance notice procedures, which apply for stockholders to nominate candidates for election as directors or to bring matters before an annual meeting of stockholders.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management. As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the DGCL, which prevents interested stockholders, such as certain stockholders holding more than 15% of our outstanding common stock, from engaging in certain business combinations unless (i) prior to the time such stockholder became an interested stockholder, the board of directors approved the transaction that resulted in such stockholder becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in such

Table of Contents

stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the common stock, or (iii) following board approval, such business combination receives the approval of the holders of at least two-thirds of our outstanding common stock not held by such interested stockholder at an annual or special meeting of stockholders.

Any provision of the Proposed Charter, the Amended and Restated Bylaws or Delaware law that has the effect of delaying, preventing or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock and could also affect the price that some investors are willing to pay for our common stock.

The Proposed Charter will provide that the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

The Proposed Charter, which will become effective prior to the completion of the Business Combination, will provide that, unless we consent in writing to the selection of an alternative forum, the (a) Court of Chancery (the “Chancery Court”) of the State of Delaware (or, in the event that the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for: (i) any derivative action, suit or proceeding brought on our behalf; (ii) any action, suit or proceeding asserting a claim of breach of fiduciary duty owed by any of our directors, officers, or stockholders to us or to our stockholders; (iii) any action, suit or proceeding asserting a claim arising pursuant to the DGCL, the Proposed Charter or the Amended and Restated Bylaws; or (iv) any action, suit or proceeding asserting a claim governed by the internal affairs doctrine; and (b) subject to the foregoing, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, such forum selection provisions shall 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 of the United States have exclusive jurisdiction. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage such lawsuits against us and our directors, officers, and other employees. Alternatively, if a court were to find the choice of forum provision contained in the Proposed Charter to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations, and financial condition.

Additionally, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. As noted above, the Proposed Charter and the Amended and Restated Bylaws will provide that the federal district courts of the United States of America shall have jurisdiction over any action arising under the Securities Act. Accordingly, there is uncertainty as to whether a court would enforce such provision. Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder.

XPDB has identified a material weakness in its internal control over financial reporting as of December 31, 2022 and June 30, 2023. If XPDB is unable to develop and maintain an effective system of internal control over financial reporting, it may not be able to accurately report its financial results in a timely manner, which may adversely affect investor confidence in us and materially and adversely affect our business and operating results.

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 annual or interim financial statements will not be prevented or detected and corrected on a timely basis. XPDB’s management concluded that there was a material weakness in internal control over financial reporting as of December 31, 2022 and June 30, 2023 relating to the accounting for accrued general and administrative expenses as well as XPDB’s tax provision. Additionally, this material weakness could result in a misstatement of the carrying value of accounts payable or accrued expenses and the reported amount of general and administrative expenses and income tax expense in the financial statements that would not be prevented or detected on a timely basis.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. We continue to evaluate steps to remediate the material weakness. These remediation measures may be time consuming and costly and there is no assurance that these initiatives will ultimately have the intended effects.

Table of Contents

If XPDB identifies any new material weaknesses in the future, any such newly identified material weakness could limit its ability to prevent or detect a misstatement of its accounts or disclosures that could result in a material misstatement of its annual or interim financial statements. In such case, XPDB may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in XPDB’s financial reporting and XPDB’s stock price may decline as a result. XPDB cannot assure you that the measures it has taken to date, or any measures we may take in the future, will be sufficient to avoid potential future material weaknesses.

Risks Related to Redemption

If third parties bring claims against us, the proceeds held in the Trust Account could be reduced and the per share redemption amount received by stockholders may be less than $10.10 per share.

Our placing of funds in the Trust Account may not protect those funds from third-party claims against us. Although we have sought and will continue to seek to have all vendors, service providers, prospective target businesses, including Montana, or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of our XPDB Public Stockholders, 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 our 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, our management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to us than any alternative. Marcum LLP, our independent registered public accounting firm, did not execute agreements with us waiving such claims to the monies held in the Trust Account.

Examples of possible instances where we 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 us and will not seek recourse against the Trust Account for any reason. Upon redemption of our Public Shares, if we are unable to complete our initial business combination within the prescribed timeframe, or upon the exercise of a redemption right in connection with our initial business combination, we will be required to provide for payment of claims of creditors that were not waived that may be brought against us within the 10 years following redemption. Accordingly, the per share redemption amount received by XPDB Public Stockholders could be less than the $10.10 per share initially held in the Trust Account, due to claims of such creditors. Our Sponsor has agreed that it will be liable to us if and to the extent any claims by a vendor for services rendered or products sold to us, or a prospective target business, with which we have discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.10 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under our indemnity of the underwriters of the XPDB IPO against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, then our Sponsor will not be responsible to the extent of any liability for such third-party claims. We have not independently verified whether our Sponsor has sufficient funds to satisfy its indemnity obligations and believe that our Sponsor’s only assets are our securities. We have not asked our Sponsor to reserve for such indemnification obligations. Therefore, we cannot assure you that our 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 our initial business combination and redemptions could be reduced to less than $10.10 per Public Share. In such event, we may not be able to complete our initial business combination, and you would receive such lesser amount per share in connection with any redemption of your Public Shares. None of our officers will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Changes in laws or regulations, or a failure to comply with any laws and regulations, may adversely affect our business, including our ability to complete the Business Combination and results of operations.

We are subject to laws and regulations enacted by national, regional and local governments. In particular, we are required to comply with certain SEC and other legal requirements. 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 our 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 our business, including our ability to complete the Business Combination, and results of operations.

On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax on certain repurchases (including redemptions) of shares by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased, and thus could cause a reduction in the value of our Class A Common Stock. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new shares issuances against the fair market value of shares repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury (the “Treasury”) has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax. Any share redemption or other share repurchase that occurs after December 31, 2022, in connection with the Business Combination, the exercise of a redemption right, the liquidation of our company, or otherwise, may be subject to the excise tax. Whether and to what extent we would be subject to the excise tax in connection with the Business Combination, the exercise of a redemption right (including in connection with the Extension), the liquidation of our company, or otherwise will depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the Business Combination or otherwise, (ii) the structure of the Business Combination, (iii) the nature and amount of any equity issuances in connection with the Business Combination (or otherwise issued not in connection with the Business Combination but issued within the same taxable year of the Business Combination) and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by us and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available on hand to complete the Business Combination and in our ability to complete the Business Combination. Further, the application of the excise tax in the event of a liquidation is uncertain.

Our independent directors may decide not to enforce the indemnification obligations of our Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to our XPDB Public Stockholders

In the event that the proceeds in the Trust Account are reduced below the lesser of (i) $10.10 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, and our Sponsor asserts that it is unable to satisfy its obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against our Sponsor to enforce its indemnification obligations.

While we currently expect that our independent directors would take legal action on our behalf against our Sponsor to enforce its indemnification obligations to us, it is possible that our independent directors in exercising their business judgment may choose not to do so 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 our independent directors choose not to enforce these indemnification obligations, the amount of funds in the Trust Account available for distribution to our XPDB Public Stockholders may be reduced below $10.10 per share.

There is no guarantee that an XPDB Public Stockholder’s decision whether to redeem their Public Shares for a pro rata portion of the Trust Account will put such stockholder in a better future economic position.

No assurance can be given as to the price at which a XPDB Public Stockholder may be able to sell the shares of our Class A Common Stock in the future following the completion of the Business Combination. Certain events following the consummation of any business combination, including the Business Combination, may cause an increase

Table of Contents

in our stock price, and may result in a lower value realized now than an XPDB stockholder might realize in the future had the stockholder not elected to redeem such stockholder’s Public Shares. Similarly, if an XPDB Public Stockholder does not redeem his, her or its shares, such stockholder will bear the risk of ownership of our Class A Common Stock after the consummation of the Business Combination, and there can be no assurance that a stockholder can sell his, her or its shares of our Class A Common Stock in the future for a greater amount than the redemption price set forth in this proxy statement/prospectus. An XPDB Public Stockholder should consult his, her or its own tax and/or financial advisor for assistance on how this may affect its individual situation.

If XPDB Public Stockholders fail to comply with the redemption requirements specified in this proxy statement/prospectus, they will not be entitled to redeem their Public Shares for a pro rata portion of the funds held in the Trust Account.

To exercise their redemption rights, holders are required to deliver their stock, either physically or electronically using the Depository Trust Company’s DWAC System, to XPDB’s transfer agent two business days prior to the vote at the Special Meeting. If a holder properly seeks redemption as described in this proxy statement/prospectus and the Business Combination with Montana is consummated, XPDB will redeem these Public Shares for a pro rata portion of funds deposited in the Trust Account and the holder will no longer own such Public Shares following the Business Combination. See the section entitled “XPDB’s Special Meeting of Stockholders — Redemption Rights” for additional information on how to exercise your redemption rights.

If, before distributing the proceeds in the Trust Account to our XPDB Public Stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of our stockholders and the per share amount that would otherwise be received by our stockholders in connection with our liquidation may be reduced.

If, before distributing the proceeds in the Trust Account to our XPDB Public Stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our stockholders. To the extent any bankruptcy claims deplete the Trust Account, the per share amount that would otherwise be received by our stockholders in connection with our liquidation may be reduced.

If, after we distribute the proceeds in the Trust Account to our XPDB Public Stockholders, we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover all amounts received by our stockholders. In addition, our board of directors may be viewed as having breached its fiduciary duty to our creditors and/or having acted in bad faith, thereby exposing itself and us to claims of punitive damages, by paying XPDB Public Stockholders from the Trust Account prior to addressing the claims of creditors.

If you or a “group” of stockholders of which you are a part are deemed to hold an aggregate of more than 15% of the Public Shares, you (or, if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 15% of the Public Shares.

An XPDB Public Stockholder, together with any of his, her or its affiliates or any other person with whom it is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from redeeming in the aggregate his, her or its Public Shares or, if part of such a group, the group’s Public Shares, in excess of 15% of the Public Shares without the consent of XPDB. Your inability to redeem any such excess Public Shares could resulting in you suffering a material loss on your investment in XPDB if you sell such excess Public Shares in open market transactions. XPDB cannot assure you that the value of such excess Public Shares will appreciate over time following the Business Combination or that the market price of the Public Shares will exceed the per-share redemption price.

However, XPDB’s stockholders’ ability to vote all of their Public Shares (including such excess shares) for or against the Business Combination Proposal is not restricted by this limitation on redemption.

Table of Contents

We may redeem your unexpired XPDB public warrants prior to their exercise at a time that is disadvantageous to you, thereby making your XPDB public warrants worthless, and Private Placement Warrants have different cashless exercise rights than other warrants issued by XPDB.

We have the ability to redeem the outstanding warrants underlying the XPDB units sold in the XPDB IPO, or the “XPDB public warrants,” at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant, in whole and not in part, upon a minimum of 30 days’ prior written notice of redemption to each warrant holder and if, and only if, the last reported sale price of the Class A Common Stock for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which we send the notice of redemption to the warrant holders equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise, such as for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like). If and when the warrants become redeemable by us, we may exercise our redemption right. Redemption of the outstanding warrants as described above could force you to: (i) exercise your warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so; (ii) sell your warrants at the then-current market price when you might otherwise wish to hold your warrants; or (iii) accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, we expect would be substantially less than the market value of your warrants.

We have established the last of the redemption criteria discussed above to prevent a redemption call unless there is, at the time of the call, a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the XPDB public warrants, each warrant holder will be entitled to exercise his, her or its XPDB public warrant prior to the scheduled redemption date. Unless we have elected to require warrant holders to exercise the warrants on a cashless basis, any such exercise would require the exercising warrant holder to pay the exercise price for each warrant being exercised. However, the price of the Class A Common Stock may fall below the $18.00 redemption trigger price (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued).

The Private Placement Warrants are identical to the XPDB public warrants except that (i) the Private Placement Warrants and the Class A Common Stock issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions, (ii) the Private Placement Warrants will be exercisable on a cashless basis at the election of such holder, whereas XPDB public warrants will only be exercisable on a cashless basis at XPDB’s election, and (iii) none of the Private Placement Warrants will be redeemable by us.

If we elect to redeem the XPDB public warrants on a cashless basis, or if the holders of the Private Placement Warrants elect to exercise their Private Placement Warrants on a cashless basis, then XPDB will not receive any cash proceeds from the exercise of such warrants. See the section entitled “Description of Securities of the Post-Combination Company — Warrants” for additional information on both the public and Private Placement Warrants.

Montana’s obligation to consummate the Business Combination is conditioned upon the Aggregate Transaction Proceeds equaling or exceeding $85.0 million. This condition may make it more difficult for us to complete the Business Combination as contemplated. If the Aggregate Transaction Proceeds Condition is waived by Montana, the business, financial condition and operations of the Post-Combination Company may be adversely affected.

The Merger Agreement provides that Montana’s obligation to consummate the Business Combination is conditioned on, among other things, as of the Closing, the Aggregate Transaction Proceeds, being equal to or greater than $85.0 million. Although the Aggregate Transaction Proceeds Condition will no longer apply upon receipt by Montana of proceeds from the Capital Raise greater than or equal to $85 million, there can be no assurance that Montana will receive such amount, or any proceeds from the Capital Raise.

Furthermore, the Aggregate Transaction Proceeds will be reduced as a result of XPDB Public Stockholders electing to redeem their Public Shares prior to the consummation of the Business Combination. If a significant number of XPDB Public Stockholders elect to redeem their Public Shares for cash, the Aggregate Transaction Proceeds may be difficult, or impossible to satisfy. If the Aggregate Transaction Proceeds Condition is not satisfied and is not waived by Montana under the terms of the Merger Agreement, then the Merger Agreement could terminate and the proposed Business Combination may not be consummated. There can be no assurance that Montana would waive the Aggregate Transaction Proceeds Condition.

If Aggregate Transaction Proceeds are less than $85.0 million and the Aggregate Transaction Proceeds Condition is waived by Montana and the Business Combination is consummated, the cash held by the Post-Combination Company may not be sufficient for the Post-Combination Company to successfully operate, and its business, financial condition and operations may be adversely affected.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Defined terms included below have the same meaning as terms defined and included elsewhere in this proxy statement/prospectus.

Introduction

The following unaudited pro forma condensed combined financial information presents the combination of financial information of XPDB and Montana, adjusted to give effect to the Business Combination and related transactions. 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” to depict the accounting for the transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). XPDB has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information.

The following unaudited pro forma condensed combined balance sheet as of June 30, 2023, assumes that the Business Combination occurred on June 30, 2023. The unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2023, and for the year ended December 31, 2022, assume that the Business Combination occurred on January 1, 2022.

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

The historical financial information of XPDB was derived from the unaudited financial statements of XPDB as of and for the six months ended June 30, 2023, and the audited financial statements of XPDB for the year ended December 31, 2022, included elsewhere in this proxy statement/prospectus. The historical financial information of Montana was derived from the unaudited financial statements of Montana as of and for the six months ended June 30, 2023, and the audited financial statements of Montana for the year ended December 31, 2022, which are included elsewhere in this proxy statement/prospectus. This information should be read together with XPDB’s and Montana’s unaudited and audited financial statements, and related notes, the sections titled “XPDB Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Montana Technologies’ Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information included elsewhere in this proxy statement/prospectus.

Description of the Business Combination

On June 5, 2023, XPDB and Merger Sub entered into the Merger Agreement with Montana, pursuant to which and subject to the terms and conditions contained in the Merger Agreement, Merger Sub will merge with and into Montana, with Montana surviving the Merger as a wholly owned subsidiary of XPDB.

of capital stock of the Post-Combination Company entitled to vote on matters submitted to a vote of the stockholders of the Post-Combination Company, (iii) in the case of holders of Montana Options, each outstanding Montana Option, whether vested or unvested, will be converted into an option to purchase, upon the same terms and conditions as are in effect with respect to the corresponding Montana Option immediately prior to the Closing, including with respect to vesting and termination-related provisions, a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to the product of (x) the number of Montana Common Units underlying such option immediately prior to the Closing and (y) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per Montana Common Unit underlying such option immediately prior to the Closing divided by (B) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, and (iv) in the case of holders of Montana Warrants, each outstanding Montana Warrant will be converted into a warrant to purchase, upon the same terms and conditions as are in effect with respect to the corresponding Montana Warrant immediately prior to the Closing, including with respect to vesting and termination-related provisions, a number of shares of Class A Common Stock equal to the product of (x) the number of Montana Common Units underlying such warrant immediately prior to the Closing and (y) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement, at an exercise price per share equal to (A) the exercise price per Montana Common Unit underlying such warrant immediately prior to the Closing divided by (B) the number of shares of Class A Common Stock issuable in respect of each Montana Common Unit in the Business Combination pursuant to the Merger Agreement.

The Eligible Equityholders will also have the opportunity to receive additional equity consideration (in each case, in accordance with their respective pro rata share) in the form of Earnout Shares only upon full completion of construction and operational viability (including all permitting, regulatory approvals and necessary or useful inspections) of new production capacity of Montana’s key components or assemblies based solely on demand from bona fide customer commitments evidenced by binding contracts (or in the sole discretion of a majority of the independent members of the Post-Combination Company Board, a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known price or pr icing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA of more than $150,000,000, which shall be determined by a majority of the independent members of the Post-Combination Company Board in their sole discretion, equal to (i) the ratio of (x) (1) the Expected Annualized EBITDA less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000.

The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing. A majority of the independent members of the Post-Combination Company Board then serving will have sole discretion in determining, among other things, the achievement of the applicable milestones, the calculations of payments of Earnout Shares to the applicable Montana Equityholders, the dates on which construction and operational viability of new production capacity is deemed completed and whether to consent to a transfer of the applicable Montana Equityholder’s right to receive Earnout Shares. Earnout Shares issuable in respect of Montana Options outstanding as of immediately prior to the effective time of the Merger may be issued to the holder of such Montana Option only if such holder continues to provide services (whether as an employee, director or individual independent contractor) to the Post-Combination Company or one of its subsidiaries through the date on which such Earnout Shares are issued, as determined by a majority of the independent members of the Post-Combination Company Board.

If the conditions for payment of the Earnout Shares are satisfied and assuming all originally designated holders of Montana Options are then still providing services to the Post-Combination Company on the date such condition is met, approximately 9% of the aggregate Earnout Shares will be payable to the holders of Montana Options (subject to the holder’s continued service with the Post-Combination Company or its subsidiaries through the applicable payment date) and 91% of the aggregate Earnout Shares will be payable to the holders of Montana Common Units, in accordance with their respective pro rata share immediately following the Closing. The settlement of the Earnout Shares to the holders of Montana Common Units contains variations in something other than the fair value of the issuer’s equity shares. As such, management determined that they should be classified as a liability and recognized at fair value at each reporting period with changes in fair value included in earnings. The Earnout Shares to the holders of Montana Options are subject to ASC 718 and would be accounted for as post-combination compensation cost.

Upon the Closing of the Business Combination, and following the conversion of the XPDB Class B Common Stock to Class A Common Stock, the Sponsor will beneficially own 7,097,500 shares of Class A Common Stock, of which (i) 5,716,764 Subject Shares will automatically vest (and shall not be subject to forfeiture) at the Closing and (ii) 1,380,736 Subject Vesting Shares shall be vested and no longer be subject to forfeiture as follows:

1) During the Vesting Period, a portion of the Subject Vesting Shares shall vest, from time to time, simultaneously with any Earnout Stock Payment, with the number of vesting shares calculated as (A) the aggregate number of Subject Vesting Shares outstanding immediately after the Closing multiplied by (B) the fraction of (x) the applicable Earnout Milestone Amount divided by (y) the Maximum Earnout Milestone Amount; and

2) (A) 690,368 shall vest at such time that the volume weighted average price of Class A Common Stock on the Nasdaq as reported by Bloomberg L.P. equals or exceeds $12.00 per share (as adjusted for extraordinary transactions, stock splits, extraordinary stock dividends, reorganizations, recapitalizations and the like) for 20 trading days within any 30 consecutive trading day period during the Vesting Period; or (B) if, prior to the $12.00 Vesting Time, any Subject Vesting Shares have vested simultaneously with any Earnout Stock Payment, then (x) if the number of Subject Vesting Shares that have vested exceeds 690,368, then no additional Subject Vesting Shares shall vest and (y) if the number of Subject Vesting Shares that have vested is less than 690,368 (the “Deficit Amount”), then a number of Subject Vesting Shares equal to 690,368 less the Deficit Amount shall vest; and

3) Any remaining Subject Vesting Shares shall vest in full at the same time that the volume weighted average price of Class A Common Stock on the Nasdaq as reported by Bloomberg L.P. equals or exceeds $14.00 per share (as adjusted for extraordinary transactions, stock splits, extraordinary stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 consecutive trading day period.

The Subject Vesting Shares do not meet the “fixed-for-fixed” criterion and thus are not considered indexed to the issuer’s stock. As such, management determined that the Subject Vesting Shares should be classified as a liability and recognized at fair value at each reporting period with changes in fair value included in earnings.

The following table illustrates varying ownership levels of the Post-Combination Company immediately following the Business Combination(1):

All of the relative percentages above are for illustrative purposes only and are based upon certain assumptions as described in the section entitled “Basis of Presentation and Glossary — Share Calculations and Ownership Percentages” and, with respect to the determination of the Assuming Maximum Contractual Redemptions Scenario in this section. Additionally, the relative percentages above assume the Business Combination was consummated on June 30, 2023. 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.

Anticipated Accounting Treatment

It is anticipated that the Business Combination will be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, although XPDB will acquire all of the outstanding equity interests of Montana in the Business Combination, XPDB will be treated as the “acquired” company and Montana will be treated as the accounting acquirer for financial statement reporting purposes. Accordingly, it is anticipated that the Business Combination will be treated as the equivalent of Montana issuing stock for the net assets of XPDB, accompanied by a recapitalization. The net assets of XPDB will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination will be those of Montana.

Montana has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances under both the Assuming Minimum Redemptions Scenario and the Assuming Maximum Contractual Redemptions Scenario:

• The Montana Equityholders will have the greatest voting interest in the Post-Combination Company;

• The Post-Combination Company Board is expected to have members, and Montana is expected to nominate the majority of the members of the Post-Combination Company Board at Closing;

• Montana will comprise the ongoing operations of the Post-Combination Company;

• Montana’s existing senior management will be the senior management of the Post-Combination Company; and

• The intended strategy and operations of the Post-Combination Company will continue Montana’s current strategy and operations.

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption for cash of XPDB Common Stock:

• Assuming Minimum Redemptions Scenario: This presentation assumes that, after the June Redemptions, no XPDB Public Stockholders will exercise redemption rights with respect to the Public Shares for a pro rata share of the funds in the Trust Account; and

The following unaudited pro forma condensed combined balance sheet as of June 30, 2023, and the unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2023, and for the year ended December 31, 2022, are based on the unaudited and audited historical financial statements of XPDB and Montana. The unaudited pro forma adjustments are based on information currently available, and assumptions and estimates underlying the unaudited pro forma adjustments are described in the accompanying notes. Actual results may differ materially from the assumptions used to present the accompanying unaudited pro forma condensed combined financial information and include immaterial rounding differences.

Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet
(in thousands, except share and per share data)

(1) Derived from the unaudited balance sheet of Montana as of June 30, 2023.

(2) Derived from the unaudited balance sheet of XPDB as of June 30, 2023.

(A) Reflects the deposit of $0.9 million to the Trust Account in connection with the Extension and the accretion of $0.9 million to the XPDB Class A Common Stock subject to possible redemption.

(B) Reflects the reimbursement of $0.5 million from a previous target of a potential business combination as a partial reimbursement of expenses incurred by XPDB.

(D) Reflects the payment of the capital markets advisory fee to Barclays.

(E) Represents preliminary estimated transaction costs expected to be incurred by XPDB and Montana of approximately $9.0 million and $4.3 million, respectively. These costs are accounted for a reduction in the combined cash account with a corresponding reduction in additional paid-in capital or accumulated deficit consistent with the treatment described in SEC Staff Accounting Bulletin Topic 5.A. These transaction costs will not recur in the Post-Combination Company’s income beyond 12 months after the transaction.

For the XPDB transaction costs, $4.0 million has been accrued as of the pro forma balance sheet date. The remaining amount of $5.0 million is reflected as an adjustment to accumulated losses. The XPDB estimated transaction costs exclude the deferred underwriting commissions included in (D) above.

For the Montana transaction costs, $1.4 million has been accrued as of the pro forma balance sheet date. The remaining amount of $2.9 million is included as an adjustment to additional paid-in capital.

(F) Represents the issuance of 33,127,115 shares of Class A Common Stock and 4,818,213 shares of Class B Common Stock to the existing Montana Equityholders (excluding 3,856,649 shares underlying the Montana Options and 388,023 shares underlying the Montana Warrants).

(G) Reflects the elimination of XPDB’s historical accumulated deficit after recording the accretion as described in (A) above, the reimbursement of expenses as described in (B) above, the transaction costs as described in (E) above and the stock-based compensation as described in (I) below.

(H) Reflects the redemption of shares for cash by the XPDB Public Stockholders upon consummation of the Business Combination. In Scenario 1, it assumes that, after the June Redemptions, no XPDB Public Stockholders will exercise redemption rights with respect to their Public Shares for a pro rata share of the funds in the Trust Account. In Scenario 2, it assumes that, after the June Redemptions, holders of 2,522,639 Public Shares redeem all of their Public Shares for approximately $10.50 per share, resulting in an aggregate redemption payment of $26.8 million.

(I) Reflects the recognition of stock-based compensation upon consummation of the Business Combination for the Founder Shares transferred from Sponsor to certain of XPDB’s directors in 2021.

(J) Reflects the conversion of XPDB Class B Common Stock into XPDB Class A Common Stock at the Business Combination.

(K) Reflects the obligation to issue Earnout Shares to Montana Equityholders (excluding the shares to be issued to Montana Option holders) upon the achievement of certain earnout milestones. The pro-forma estimated fair value of the Earnout Shares was determined with a Monte Carlo simulation using a distribution of potential outcomes for expected earnings before interest, taxes, depreciation, and amortization (“EBITDA”) and stock price at expected Commission Dates, utilizing a correlation coefficient for EBITDA and stock price, and assuming $50 million of Annualized EBITDA per production line, with six production lines commissioned over a five-year period. EBITDA was discounted to the valuation date with a weighted average cost of capital estimate and forecasted to each estimated Commission Date. Earnout mechanics at each estimated Commission Date were assessed, and if the Earnout Thresholds were achieved, the future value of the Earnout Shares was discounted to the Valuation Date utilizing a risk-free rate commensurate with the overall term. Expected EBITDA assumes

that each production line will achieve equivalent production generating $50 million of Annualized EBITDA. The Commission Dates used reflected XPDB’s management’s best estimates regarding the time to complete full construction and operational viability of a production line, including all permitting, regulatory approvals and necessary or useful inspections. The Earnout term of 5 years and the Earnout mechanics represent contractual inputs. Assumptions such as risk-free rate, stock price, volatility, and discount rate were based on market data. See the following summary of inputs:

Monte Carlo simulation starting stock price	$	10.00
Simulation term (years)		5.0
Simulation term risk-free rate		4.1	%
Selected discount rate		25.0	%
Selected asset volatility		35.0	%
Selected equity volatility		35.0	%

The fair value of the Earnout Shares will be determined by updating the valuation, utilizing the mechanics and methodology described above. At each valuation date, company management will assess the EBITDA forecast and Commission Dates, and provide any updates to the assumptions based on known or knowable information as of the valuation date. Market dependent assumptions such as volatility, discount rate, risk-free rate, and stock price will be updated at each valuation date and adjusted as applicable. Additionally, the term will be adjusted for the passage of time at each valuation date and any payments achieved and paid in prior periods, if applicable.

While we will need to assess the facts and circumstances related to the Earnout Shares at each future valuation date, the two largest drivers of the fair value of the Earnout Shares are the forecasted EBITDA metrics and the future stock price at each future date. Adjusting each of those metrics up and down 20% would yield a range of possible outcomes from approximately $56 million to approximately $109 million.

(L) Reflects the fair value of the Subject Vesting Shares issued to holders of XPDB Class B Common Stock.

(M) Reflects the repayment of related party promissory notes upon consummation of the Business Combination.

(N) Reflects the recognition of additional excise tax payable under the maximum redemption scenario upon the consummation of the Business Combination.

(O) Reflects the reclassification among equity to avoid negative additional paid-in capital.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1. Basis of Presentation

The Business Combination will be accounted for as a reverse recapitalization in accordance with GAAP as Montana has been determined to be the accounting acquirer, primarily due to the fact that Montana Equityholders will continue to control the Post-Combination Company. Under this method of accounting, although XPDB will acquire all of the outstanding equity interests of Montana in the Business Combination, XPDB will be treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination will be treated as the equivalent of Montana issuing stock for the net assets of XPDB, accompanied by a recapitalization. The net assets of XPDB will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination will be those of Montana.

The unaudited pro forma condensed combined balance sheet as of June 30, 2023, assumes that the Business Combination and related transactions occurred on June 30, 2023. The unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2023, and for the year ended December 31, 2022, presents pro forma effect to the Business Combination as if it had been completed on January 1, 2022.

The unaudited pro forma condensed combined balance sheet as of June 30, 2023, has been prepared using, and should be read in conjunction with, the following:

• XPDB’s unaudited balance sheet as of June 30, 2023 and the related notes for the six months ended June 30, 2023, included elsewhere in this proxy statement/prospectus; and

• Montana’s unaudited consolidated balance sheet as of June 30, 2023 and the related notes for the six months ended June 30, 2023, included elsewhere in this proxy statement/prospectus.

The unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2023, has been prepared using, and should be read in conjunction with, the following:

• XPDB’s unaudited statement of operations for the six months ended June 30, 2023, and the related notes, included elsewhere in this proxy statement/prospectus; and

• Montana’s unaudited consolidated statement of operations for the six months ended June 30, 2023, and the related notes, included elsewhere in this proxy statement/prospectus.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2022, has been prepared using, and should be read in conjunction with, the following:

• XPDB’s audited statement of operations for the year ended December 31, 2022, and the related notes, included elsewhere in this proxy statement/prospectus; and

• Montana’s audited consolidated statement of operations for the year ended December 31, 2022, and the related notes, included elsewhere in this proxy statement/prospectus.

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

Table of Contents

presents additional adjustments to reflect the effect of the Assuming Maximum Contractual Redemptions Scenario. The “Assuming Maximum Contractual Redemptions Scenario” represents the maximum number of Public Shares that may be redeemed and still satisfy the “Aggregate Transaction Proceeds Condition”. In the event XPDB’s Aggregate Transaction Proceeds at Closing is insufficient to meet the Aggregate Transaction Proceeds Condition due to redemptions by XPDB Public Stockholders beyond what is represented in the “Assuming Maximum Contractual Redemptions Scenario,” a condition to the Closing would not be met and the Business Combination may not be consummated. However, the Aggregate Transaction Proceeds Condition is a contractual condition that may be waived by Montana or may be modified by the parties to the Merger Agreement and if the applicable parties agree to waive or modify such condition, up to an additional 8,055,539 Public Shares may be redeemed.

As the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings or cost savings that may be associated with the Business Combination.

The pro forma adjustments reflecting the consummation of the Business Combination are based on certain currently available information and certain assumptions and methodologies that XPDB believes are reasonable under the circumstances. The unaudited condensed pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments and it is possible the difference may be material. XPDB believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Business Combination based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position of the Post-Combination Company would have been had the Business Combination taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the Post-Combination Company. They should be read in conjunction with the historical financial statements and notes thereto of XPDB and Montana.

2. Accounting Policies

Upon consummation of the Business Combination, management of the Post-Combination Company will perform a comprehensive review of the two entities’ accounting policies. As a result of the review, management of the Post-Combination Company may identify differences between the accounting policies of the two entities which, when conformed, could have a material impact on the financial statements of the Post-Combination Company. Based on its initial analysis, management of the Post-Combination Company 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.

3. Adjustments to Unaudited Pro Forma Condensed Combined Financial Information

The unaudited pro forma condensed combined financial information has been prepared to illustrate the effect of the Business Combination and has been prepared for informational purposes only.

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” to depict the Transaction Accounting Adjustments and present the Management’s Adjustments. XPDB has elected not to present Management’s Adjustments and is only presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information. The historical financial statements have been adjusted in the unaudited pro forma condensed combined financial information to include all necessary Transaction Accounting Adjustments pursuant to Article 11 of Regulation S-X, including those that are not expected to have a continuing impact.

Table of Contents

The audited historical financial statements have been adjusted in the unaudited pro forma condensed combined financial information to give pro forma effect to Transaction Accounting Adjustments that reflect the accounting for the transaction under GAAP. Montana and XPDB have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The pro forma combined statement of operations does not reflect a provision for income taxes or any amounts that would have resulted had the Post-Combination Company filed consolidated income tax returns during the periods presented. The pro forma condensed combined balance sheet does not reflect the deferred taxes of the Post-Combination Company as a result of the Business Combination. Since it is likely that the Post-Combination Company will record a valuation allowance against the total U.S. and state deferred tax assets given the net operating losses as the recoverability of the tax assets is uncertain, the tax provision is zero.

The pro forma basic and diluted earnings per share amounts presented in the unaudited pro forma condensed combined statement of operations are based upon the number of the Post-Combination Company’s shares outstanding, assuming the Business Combination occurred on January 1, 2022.

The unaudited pro forma condensed combined financial information has been prepared assuming two alternative levels of redemption for cash of XPDB Common Stock as of June 30, 2023:

	As of June 30, 2023
(in thousands, except share and per share data)	Scenario 1 Assuming Minimum Redemptions			Scenario 2 Assuming Maximum Contractual Redemptions
Net loss	$	(8,872	)	$	(8,872	)
Stockholders’ equity (deficit)		6,417			(20,660	)
Weighted average shares outstanding of common stock(1)		55,741,006			53,188,367
Net loss per common share, basic and diluted	$	(0.16	)	$	(0.17	)
Book value (deficit) per share	$	0.12		$	(0.39	)

____________

(1) For the purposes of calculating diluted earnings per share, all outstanding XPDB public warrants, Private Placement Warrants, Montana Options, and Montana Warrants should have been assumed to have been exercised. However, since this results in anti-dilution, the effect of such exercise was not included in calculation of diluted loss per share.

Table of Contents

Vote of the Sponsor, Directors and Officers

XPDB has entered into an agreement with the Sponsor and certain of XPDB’s directors, pursuant to which each agreed to vote any shares of XPDB Common Stock owned by them in favor of each of the Proposals presented at the Special Meeting. As a result, in addition to our Initial Stockholders’ Founder Shares, we would need 1,710,340, or 16.12%, of the 10,608,178 Public Shares outstanding as of June 30, 2023 to be voted in favor of each of the Proposals in order for them to be approved (assuming all issued and outstanding shares are voted).

The Sponsor and XPDB’s directors and officers have waived any redemption rights, including with respect to any Public Shares purchased in the XPDB IPO or in the aftermarket, in connection an initial business combination. The Founder Shares held by the Initial Stockholders have no redemption rights upon our liquidation and will be worthless if no business combination is effected by us within the Completion Window. However, the Sponsor and XPDB’s directors and officers are entitled to redemption rights upon our liquidation with respect to any Public Shares they may own.

Quorum and Required Vote for Proposals for the Special Meeting

The approval of each of the Business Combination Proposal, the Governance Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal and the Adjournment Proposal, if presented, requires the affirmative vote (in person or by proxy) of the holders of a majority of the shares of XPDB Class A Common Stock and XPDB Class B Common Stock entitled to vote and actually cast thereon at the Special Meeting, voting as a single class. Accordingly, a stockholder’s failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting, as well as an abstention from voting and a broker non-vote with regard to each of the Business Combination Proposal, the Governance Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal or the Adjournment Proposal, if presented, will have no effect on the Business Combination Proposal, the Governance Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal or the Adjournment Proposal. The Sponsor and certain of XPDB’s directors have agreed to vote their shares of XPDB Common Stock in favor of each of the Proposals presented at the Special Meeting. As a result, in addition to our Initial Stockholders’ Founder Shares, we would need , or %, of the Public Shares outstanding as of the Record Date to be voted in favor of each of the Proposals in order for them to be approved (assuming all issued and outstanding shares are voted).

Directors are elected by a plurality of all of the votes cast by the holders of XPDB Class B Common Stock, voting as a separate class, present in person (which would include presence at a virtual meeting) or represented by proxy at the Special Meeting and entitled to vote thereon. This means that the director nominees who receive the most affirmative votes will be elected. Stockholders may not cumulate their votes with respect to the election of directors. Accordingly, a stockholder’s failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting, as well as an abstention from voting and a broker non-vote with regard to election of directors, will have no effect on the election of directors.

Table of Contents

Business Combination is not conditioned on the Governance Proposal or the Adjournment Proposal. If the Business Combination Proposal is not approved, the other proposals (except the Adjournment Proposal) will not be presented to the stockholders for a vote.

It is important for you to note that in the event that the Business Combination Proposal, the Charter Proposal, the Nasdaq Proposal, the Incentive Plan Proposal or the Employee Stock Purchase Plan Proposal do not receive the requisite vote for approval, XPDB will not consummate the Business Combination. If XPDB does not consummate the Business Combination and fails to complete an initial business combination within the Completion Window, it will be required to dissolve and liquidate the Trust Account by returning the then remaining funds in such account to the XPDB Public Stockholders.

Recommendation of XPDB Board of Directors

The XPDB Board unanimously determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, were advisable, fair to, and in the best interests of, XPDB and its stockholders. Accordingly, the XPDB Board unanimously recommends that its stockholders vote “FOR” each of the Business Combination Proposal, the Charter Proposal, the Governance Proposal, the Director Election Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal and the Adjournment Proposal.

In considering the recommendation of the XPDB Board to vote in favor of approval of the Proposals, stockholders should keep in mind that the Sponsor and XPDB’s directors and officers have interests in such Proposals that are different from or in addition to (and which may conflict with) those of XPDB stockholders. Stockholders should take these interests into account in deciding whether to approve the proposals presented at the Special Meeting, including the Business Combination Proposal. These interests include, among other things:

• If the Business Combination with Montana or another business combination is not consummated within the Completion Window, XPDB will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and the XPDB Board, dissolving and liquidating. In such event, the 7,187,500 Founder Shares purchased by the Sponsor for an aggregate purchase price of $25,000, or approximately $0.004 per share, and held by the Initial Stockholders would be worthless because the Initial Stockholders are not entitled to participate in any redemption or distribution with respect to such shares. Such shares had an aggregate market value of $ based upon the closing price of $ per share of XPDB Class A Common Stock on the Nasdaq on the Record Date. Certain Founder Shares are subject to certain time- and performance-based vesting provisions as described under “Other Agreements — Sponsor Support Agreement.”

• XPDB’s directors and officers, and their affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on XPDB’s behalf, such as identifying and investigating possible business targets and business combinations. However, if XPDB fails to consummate a business combination within the Completion Window, they will not have any claim against the Trust Account for reimbursement. Accordingly, XPDB may not be able to reimburse these expenses if the Business Combination or another business combination is not consummated within the Completion Window. Additionally, the Sponsor is entitled to $20,000 per month for office space, secretarial and administrative services provided to XPDB’s management team through the earlier of consummation of the Business Combination and liquidation for each month since December 9, 2021, which will be paid at the consummation of the Business Combination.

Table of Contents

• The continued indemnification of current directors and officers and the continuation of directors’ and officers’ liability insurance.

Abstentions and Broker Non-Votes

Abstentions are considered present for the purposes of establishing a quorum and will have the same effect as a vote “AGAINST” the Charter Proposal. Broker non-votes are not considered present for the purposes of establishing a quorum and will have the effect of a vote “AGAINST” the Charter Proposal. Abstentions and broker non-votes will have no effect on the Business Combination Proposal, the Governance Proposal, the Director Election Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal and the Adjournment Proposal.

In general, if your shares are held in “street” name and you do not instruct your broker, bank or other nominee on a timely basis on how to vote your shares, your broker, bank or other nominee, in its sole discretion, may either leave your shares unvoted or vote your shares on routine matters, but not on any non-routine matters. None of the Proposals at the Special Meeting are routine matters. As such, without your voting instructions, your brokerage firm cannot vote your shares on any proposal to be voted on at the Special Meeting.

Certain Engagements in Connection with the Business Combination and Related Transactions

XPDB engaged Barclays to act as its exclusive capital markets advisor. Barclays will receive fees, reimbursement and indemnification in connection therewith.

Barclays was entitled to receive a Deferred Discount (as defined in the IPO Underwriting Agreement, dated as of December 9, 2021 (the “IPO Underwriting Agreement”), by and between XPDB, Barclays and BofA) in connection with its role as a joint bookrunner for the XPDB IPO in the amount of approximately $6 million. BofA waived its entitlement to its portion of a Deferred Discount as of June 20, 2023. Barclays has agreed to credit its $6 million capital markets advisory fee against its portion of the Deferred Discount. All of the fees and reimbursements described above are conditioned on the completion of the Business Combination.

In addition, Barclays (together with its affiliates) is a full service financial institution engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investing, hedging, market making, brokerage and other financial and non-financial activities and services. In addition, Barclays and its respective affiliates may provide investment banking and other commercial dealings to XPDB, Montana and their respective affiliates in the future, for which they would expect to receive customary compensation.

In addition, in the ordinary course of its business activities, Barclays and its affiliates, officers, directors and employees may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for its own accounts and for the accounts of its customers. Such investments and securities activities may involve securities and/or instruments of XPDB or Montana, or their respective affiliates. Barclays and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that it acquires, long and/or short positions in such securities and instruments.

If your shares are owned directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered, with respect to those shares, the “stockholder of record.” If your shares are held in a stock brokerage account or by a bank or other nominee or intermediary, you are considered the beneficial owner of shares held in “street name” and are considered a “non-record (beneficial) stockholder.”

If you are an XPDB stockholder of record you may use the enclosed proxy card to tell the persons named as proxies how to vote your shares. If you properly complete, sign and date your proxy card, your shares will be voted in accordance with your instructions. The named proxies will vote all shares at the Special Meeting for which proxies have been properly submitted and not revoked. If you sign and return your proxy card but do not mark your card to tell the proxies how to vote, your shares will be voted “FOR” each of the Proposals presented at the Special Meeting.

Your shares will be counted for purposes of determining a quorum if you vote:

• via the Internet;

• by telephone;

• by submitting a properly executed proxy card or voting instruction form by mail; or

• electronically at the Special Meeting.

Abstentions will be counted for determining whether a quorum is present for the Special Meeting, but broker non-votes will not.

Voting instructions are printed on the proxy card or voting information form you received. Either method of submitting a proxy will enable your shares to be represented and voted at the Special Meeting.

Voting Your Shares — Beneficial Owners

If your shares are held in an account at a brokerage firm, bank or other nominee, then you are the beneficial owner of shares held in “street name” and this proxy statement/prospectus is being sent to you by that broker, bank or other nominee. The broker, bank or other nominee holding your account is considered to be the stockholder of record for purposes of voting at the Special Meeting. As a beneficial owner, you have the right to direct your broker, bank or other nominee regarding how to vote the shares in your account by following the instructions that the broker, bank or other nominee provides you along with this proxy statement/prospectus. Your broker, bank or other nominee may have an earlier deadline by which you must provide instructions to it as to how to vote your shares. As a beneficial owner, if you wish to vote at the Special Meeting, you will need to bring to the Special Meeting a legal proxy from your broker, bank or other nominee authorizing you to vote those shares. That is the only way we can be sure that the broker, bank or nominee has not already voted your shares of XPDB Common Stock.

Revoking Your Proxy

If you are a stockholder and you give a proxy, you may revoke it at any time before it is exercised by doing any one of the following:

1. you may send another proxy card with a later date;

2. you may notify XPDB’s Secretary in writing before the Special Meeting that you have revoked your proxy; or

3. you may attend the Special Meeting and vote electronically by visiting https://www.cstproxy.com/xpdispacii/sm2023 and entering the control number found on your proxy card, instruction form or notice you previously received. Attendance at the Special Meeting will not, in and of itself, revoke a proxy.

If your shares are held in “street name” or are in a margin or similar account, you should contact your broker for information on how to change or revoke your voting instructions.

No Additional Matters

The Special Meeting has been called only to consider the approval of the Business Combination Proposal, the Charter Proposal, the Governance Proposal, the Director Election Proposal, the Nasdaq Proposal, the Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal and the Adjournment Proposal. Under XPDB’s bylaws, other than procedural matters incident to the conduct of the Special Meeting, no other matters may be considered at the Special Meeting if they are not included in this proxy statement/prospectus, which serves as the notice of the Special Meeting.

If you are a stockholder and have any questions about how to vote or direct a vote in respect of your shares of XPDB Common Stock, you may call Morrow Sodali LLC, XPDB’s proxy solicitor, at (800) 662-5200.

Redemption Rights

Holders of Public Shares may seek to redeem their shares for cash, regardless of whether they vote for or against, or abstain from voting on, the Business Combination Proposal. Any stockholder holding Public Shares may demand that XPDB redeem such shares for a pro rata portion of the Trust Account (which, for illustrative purposes, was approximately $ per Public Share as of the Record Date), calculated as of two business days prior to the anticipated consummation of the Business Combination. If a holder properly seeks redemption as described in this section and the Business Combination with Montana is consummated, XPDB will redeem these shares for a pro rata portion of funds deposited in the Trust Account and the holder will no longer own these shares following the Business Combination.

Notwithstanding the foregoing, a holder of Public Shares, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption rights with respect to more than 15% of the Public Shares without the consent of XPDB. Accordingly, all Public Shares in excess of 15% held by an XPDB Public Stockholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group,” will not be redeemed for cash without the consent of XPDB.

The Sponsor and XPDB’s directors and officers will not have redemption rights with respect to any shares of XPDB Common Stock owned by them, directly or indirectly in connection with the Business Combination.

XPDB Public Stockholders may seek to redeem their Public Shares for cash, regardless of whether they vote for or against, or abstain from voting on, the Business Combination Proposal. Holders may demand redemption by delivering their Public Shares, either physically or electronically using the Depository Trust Company’s DWAC System, to XPDB’s transfer agent no later than the second business day preceding the vote on the Business Combination Proposal. In order to exercise your redemption right, you need to identify yourself as a beneficial holder and provide your legal name, phone number and address in your written demand. If you hold the 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 for cash. There is a nominal cost associated with this tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge the tendering broker $80.00 and it would be up to the broker whether or not to pass this cost on to the redeeming stockholder. In the event the proposed Business Combination is not consummated this may result in an additional cost to XPDB Public Stockholders for the return of their Public Shares.

Any request to redeem such Public Shares, once made, may be withdrawn, with XPDB’s consent, at any time up to the vote on the Business Combination Proposal. Furthermore, if a holder of a Public Share delivered its certificate in connection with an election of its redemption and subsequently decides prior to the applicable date not to elect to exercise such rights, it may simply request that the transfer agent return the certificate (physically or electronically).

If the Business Combination is not approved or completed for any reason, then XPDB Public Stockholders who elected to exercise their redemption rights will not be entitled to redeem their Public Shares for a pro rata portion of the Trust Account, as applicable. In such case, XPDB will promptly return any Public Shares delivered by XPDB Public Stockholders.

Table of Contents

The closing price of XPDB Class A Common Stock on , 2023, the Record Date, was $ . The cash held in the Trust Account on such date was approximately $ million (approximately $ per Public Share). Prior to exercising redemption rights, stockholders should verify the market price of XPDB Common Stock as they may receive higher proceeds from the sale of their XPDB Common Stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. XPDB cannot assure its stockholders that they will be able to sell their shares of XPDB Common Stock 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 its securities when its stockholders wish to sell their shares.

If a holder of Public Shares exercises its redemption rights, then it will be exchanging its shares of XPDB Common Stock for cash and will no longer own those Public Shares. You will be entitled to receive cash for these Public Shares only if you properly demand redemption no later than the second business day preceding the vote on the Business Combination Proposal by delivering your stock certificate (either physically or electronically) to XPDB’s transfer agent prior to the vote at the Special Meeting, and the Business Combination is consummated. In order to exercise your redemption right, you need to identify yourself as a beneficial holder and provide your legal name, phone number and address in your written demand.

For a discussion of the material U.S. federal income tax considerations for XPDB Public Stockholders with respect to the exercise of these redemption rights, see “Material U.S. Federal Income Tax Consequences — Tax Consequences of a Redemption of Public Shares”. The consequences of a redemption to any particular holder of Public Shares will depend on that holder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine your tax consequences from the exercise of your redemption rights, including the applicability and effect of U.S. federal, state and local and non-U.S. income and other tax laws in light of your particular circumstances.

Appraisal Rights

Stockholders, unitholders and warrant holders of XPDB do not have appraisal rights in connection the Business Combination under the DGCL.

Proxy Solicitation Costs

XPDB is soliciting proxies on behalf of the XPDB Board. This solicitation is being made by mail but also may be made by telephone or in person. XPDB and its directors, officers and employees may also solicit proxies in person, by telephone or by other electronic means. XPDB will bear the cost of the solicitation.

XPDB has hired Morrow Sodali LLC to assist in the proxy solicitation process. XPDB will pay that firm a fee of $27,500 plus disbursements. Such payment will be made from non-Trust Account funds.

XPDB 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. XPDB will reimburse them for their reasonable expenses.

The Initial Stockholders

As of the Record Date, the Initial Stockholders of record were entitled to vote an aggregate of Founder Shares that were issued prior to the XPDB IPO. Such shares currently constitute approximately % of the outstanding shares of XPDB Common Stock. The Initial Stockholders have agreed to vote the Founder Shares, as well as any shares of XPDB Common Stock acquired in the aftermarket, in favor of each of the Proposals presented at the Special Meeting. The Founder Shares have no right to participate in any redemption distribution and will be worthless if no business combination is effected by XPDB.

Upon consummation of the Business Combination, under the Sponsor Support Agreement, certain shares of Class A Common Stock following the conversion of the Founder Shares will be subject to (i) certain lock-up restrictions and (ii) certain time and performance-based vesting provisions. See the section entitled “Other Agreements — Sponsor Support Agreement” for more information.

Table of Contents

Purchases of XPDB Shares

At any time prior to the Special Meeting, during a period when they are not then aware of any material nonpublic information regarding XPDB or its securities, the Sponsor, Montana, the Montana Equityholders and/or their respective affiliates may purchase shares from institutional and other investors who vote, or indicate an intention to vote, against the Business Combination Proposal, or execute agreements to purchase shares from such investors in the future, or they may enter into transactions with such investors and others to provide them with incentives to acquire shares of XPDB Common Stock or vote their shares in favor of the Business Combination Proposal. The purpose of such share purchases and other transactions would be to increase the likelihood of satisfaction of the requirements to consummate the Business Combination where it appears that such requirements would otherwise not be met. While the exact nature of any such incentives has not been determined as of the date of this proxy statement/prospectus, they might include, without limitation, arrangements to protect such investors or holders against potential loss in value of their shares, including the granting of put options and, with Montana’s consent, the transfer to such investors or holders of shares or warrants owned by the Sponsor for nominal value.

Entering into any such arrangements may have a depressive effect on XPDB Common Stock. For example, as a result of these arrangements, an investor or holder may have the ability to effectively purchase shares at a price lower than market and may therefore be more likely to sell the shares he owns, either prior to or immediately after the Special Meeting.

If such transactions are effected, the consequence could be to cause the Business Combination to be approved in circumstances where such approval could not otherwise be obtained. Purchases of shares by the persons described above would allow them to exert more influence over the approval of the Business Combination Proposal and other proposals and would likely increase the chances that such proposals would be approved.

No agreements dealing with the above arrangements or purchases have been entered into as of the date of this proxy statement/prospectus by the Sponsor, Montana, the Montana Equityholders or any of their respective affiliates. XPDB will file a Current Report on Form 8-K to disclose arrangements entered into or significant purchases made by any of the aforementioned persons that would affect the vote on the Business Combination Proposal or the satisfaction of any closing conditions. Any such report will include descriptions of any arrangements entered into or significant purchases by any of the aforementioned persons.

PROPOSAL NO. 1 — THE BUSINESS COMBINATION PROPOSAL

Overview

Holders of XPDB Common Stock are being asked to approve the Merger Agreement and the transactions contemplated thereby, including the Business Combination. XPDB stockholders should read carefully this proxy statement/prospectus in its entirety for more detailed information concerning the Merger Agreement, dated as of June 5, 2023, which is attached as Annex A to this proxy statement/prospectus.

You are urged to read carefully the Merger Agreement in its entirety before voting on this proposal.

Vote Required for Approval

This Business Combination Proposal (and consequently, the Merger Agreement and the transactions contemplated thereby, including the Business Combination) will be adopted and approved only if at least a majority of the votes cast by the stockholders present in person (which would include presence at a virtual meeting) or represented by proxy at the Special Meeting vote “FOR” the Business Combination Proposal.

Failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting, abstentions and broker non-votes will have no effect on the Business Combination Proposal.

The Business Combination is conditioned upon the approval of the Business Combination Proposal, subject to the terms of the Merger Agreement. If the Business Combination Proposal is not approved, the other Proposals (except the Adjournment Proposal, as described below) will not be presented to the stockholders for a vote.

See the section entitled “Other Agreements — Sponsor Support Agreement” for more information.

Recommendation of the XPDB Board

THE XPDB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE XPDB STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE BUSINESS COMBINATION PROPOSAL.

The existence of financial and personal interests of one or more of XPDB’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 XPDB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Business Combination Proposal. In addition, XPDB’s directors, executive officers and the Sponsor and its affiliates may have interests in the Business Combination that may conflict with your interests as a stockholder. See the section titled “The Business Combination — Interests of the Sponsor and XPDB’s Directors and Executive Officers in the Business Combination” for a further discussion of these considerations.

PROPOSAL NO. 2 — THE CHARTER PROPOSAL

Overview

Our stockholders are being asked to adopt the Proposed Charter in the form attached hereto as Annex B, which, in the judgment of the XPDB Board, is necessary to adequately address the needs of the Post-Combination Company.

The following is a summary of the key changes effected by the Proposed Charter, but this summary is qualified in its entirety by reference to the full text of the Proposed Charter, a copy of which is included as Annex B:

• Changes to Authorized Capital Stock — the Existing Charter authorized the issuance of 551,000,000 total shares, consisting of (a) 550,000,000 shares of XPDB Common Stock, of which (i) 500,000,000 shares were XPDB Class A Common Stock, and (ii) 50,000,000 shares were XPDB Class B Common Stock, and (b) 1,000,000 shares were preferred stock. The Proposed Charter authorizes the issuance of total shares, consisting of (a) shares of common stock of which (i) shares are Class A Common Stock, and (ii) shares are Class B Common Stock, and (b) shares of preferred stock;

• Dual Class Stock Structure — provide for a dual class stock structure in which shares of Class A Common Stock will each have one vote per share and shares of Class B Common Stock, par value $0.0001 per share, with a number of votes per share necessary such that the Montana Equityholders collectively would own at the Closing at least 80% of the voting power of all classes of stock of the Post-Combination Company entitled to vote; provided, however, that the number of votes per share shall be at least one (1) vote per share;

• Required Vote to Amend the Charter — require an affirmative vote of holders of at least two-thirds (66 and 2/3%) of the voting power of all the then outstanding shares of voting stock of the Post-Combination Company, voting together as a single class, to amend, alter, repeal or rescind, in whole or in part, certain provisions of the Proposed Charter;

• Required Vote to Amend the Bylaws — require an affirmative vote of holders of at least two-thirds (66 and 2/3%) of the voting power of all the then outstanding shares of voting stock of the Post-Combination Company entitled to vote generally in an election of directors to adopt, amend, alter, repeal or rescind the Amended and Restated Bylaws;

• Director Removal — provide for the removal of directors with cause only by stockholders voting at least two-thirds (66 and 2/3%) of the voting power of all of the then outstanding shares of voting stock of the Post-Combination Company entitled to vote at an election of directors;

• Removal of Blank Check Company Provisions — eliminate various provisions applicable only to blank check companies, including business combination requirements; and

• Change of XPDB’s name — change XPDB’s name to “Montana Technologies Corporation.”

Reasons for the Amendments

Each of these amendments was negotiated as part of the Business Combination. The XPDB Board’s reasons for proposing each of these amendments to the Existing Charter is set forth below.

Changes to Authorized Capital Stock

Our Existing Charter authorizes 551,000,000 shares, consisting of (a) 550,000,000 shares of XPDB Common Stock, including (i) 500,000,000 shares of XPDB Class A Common Stock and (ii) 50,000,000 shares of XPDB Class B Common Stock, and (b) 1,000,000 shares of preferred stock. The Proposed Charter provides that XPDB will be authorized to issue shares, consisting of shares of Class A Common Stock, shares of Class B Common Stock and shares of preferred stock.

Table of Contents

This amendment also increases the authorized number of shares because the XPDB Board believes that it is important for us to have available for issuance a number of authorized shares of common stock and preferred stock sufficient to support our growth and to provide flexibility for future corporate needs (including, if needed, as part of financing for future growth acquisitions). The shares would be issuable as consideration for the Merger and the other transactions contemplated in this proxy statement/prospectus, and for any proper corporate purpose, including future acquisitions, capital raising transactions consisting of equity or convertible debt, stock dividends or issuances under current and any future stock incentive plans.

The XPDB Board believes that these additional shares will provide us with needed flexibility to issue shares in the future in a timely manner and under circumstances we consider favorable without incurring the risk, delay and potential expense incident to obtaining stockholder approval for a particular issuance.

Dual Class Stock Structure

At present, our Existing Charter provides for a dual class stock structure consisting of shares of XPDB Class A Common Stock and XPDB Class B Common Stock, each with one vote per share. The Proposed Charter provides for a similar dual class stock structure, except that shares of Class A Common Stock will each have one vote per share and shares of Class B Common Stock will have a number of votes per share. necessary such that the Montana Equityholders collectively would own at the Closing at least 80% of the voting power of all classes of stock of XPDB entitled to vote; provided, however, that the number of votes per share shall be at least one (1) vote per share. We believe that providing holders of Class B Common Stock of the Post-Combination Company is necessary to further the business arrangements contemplated by the Business Combination and ensure the Business Combination receives the parties’ intended tax treatment.

Required Vote to Amend the Charter

At present, our Existing Charter may only be amended with the approval of a majority of the XPDB Board and (i) the holders of a majority of the shares of XPDB Class B Common Stock then outstanding, voting separately as a single class, and (ii) the holders of a majority of the shares of XPDB Common Stock entitled to vote, voting as a single class. This amendment provides for the requirement of an affirmative vote of holders of at least two-thirds (66 and 2/3%) of the voting power of all the then outstanding shares of voting stock of the Post-Combination Company, voting together as a single class, to amend, alter, repeal or rescind certain provisions of the Proposed Charter. We believe that supermajority voting requirements are appropriate at this time to protect all stockholders against the potential self-interested actions by one or a few large stockholders. In reaching this conclusion, the XPDB Board was cognizant of the potential for certain stockholders to hold a substantial beneficial ownership of our common stock following the Business Combination. We further believe that going forward, a supermajority voting requirement encourages the person seeking control of the Post-Combination Company to negotiate with the Post-Combination Company Board to reach terms that are appropriate for all stockholders.

Required Vote to Amend the Bylaws

At present, our Existing Charter provides that our bylaws may be amended by the affirmative vote of the holders of a majority of the voting power of all then outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class. This amendment provides for the requirement of an affirmative vote of holders of at least two-thirds (66 and 2/3%) of the voting power of all the then outstanding shares of voting stock of the Post-Combination Company entitled to vote generally in an election of directors to adopt, amend, alter, repeal or rescind the Amended and Restated Bylaws. The ability of the majority of the XPDB Board to amend the bylaws remains unchanged. We believe that supermajority voting requirements are appropriate at this time to protect all stockholders against the potential self-interested actions by one or a few large stockholders. In reaching this conclusion, the XPDB Board was cognizant of the potential for certain stockholders to hold a substantial beneficial ownership of our common stock following the Business Combination. We further believe that going forward, a supermajority voting requirement encourages the person seeking control of the Post-Combination Company to negotiate with the Post-Combination Company Board to reach terms that are appropriate for all stockholders.

Table of Contents

Director Removal

At present, our Existing Charter provides that, directors may be removed from office at any time, but only for cause and only by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class. This amendment provides for the removal of directors with cause only by stockholders voting at least two-thirds (66 and 2/3%) of the voting power of all of the then outstanding shares of voting stock of the Post-Combination Company entitled to vote at an election of directors. We believe that supermajority voting requirements are appropriate at this time to protect all stockholders against the potential self-interested actions by one or a few large stockholders. In reaching this conclusion, the XPDB Board was cognizant of the potential for certain stockholders to hold a substantial beneficial ownership of our common stock following the Business Combination. We further believe that going forward, a supermajority voting requirement encourages the person seeking control of the Post-Combination Company to negotiate with the Post-Combination Company Board to reach terms that are appropriate for all stockholders.

Removal of Blank Check Company Provisions

Our Existing Charter contains various provisions applicable only to blank check companies. This amendment eliminates certain provisions related to our status as a blank check company, which is desirable because these provisions will serve no purpose following the Business Combination. For example, these proposed amendments remove the requirement to dissolve the Post-Combination Company and allow it to continue as a corporate entity with perpetual existence following consummation of the Business Combination. Perpetual existence is the usual period of existence for corporations and we believe it is the most appropriate period for the Post-Combination Company following the Business Combination. In addition, certain other provisions in our Existing Charter require that proceeds from the XPDB IPO be held in the Trust Account until a business combination or liquidation has occurred. These provisions cease to apply once the Business Combination is consummated.

Change of XPDB’s Name

Changing the corporate name from “Power & Digital Infrastructure Acquisition II Corp.” to “Montana Technologies Corporation” is desirable to reflect the Business Combination and to align the name of the Post-Combination Company with the existing operating business of Montana.

Vote Required for Approval

If the Business Combination Proposal is not approved, the Charter Proposal will not be presented at the Special Meeting. The Charter Proposal will be approved and adopted only if: (i) the holders of a majority of the shares of XPDB Class B Common Stock then outstanding, voting separately as a single class, and (ii) the holders of a majority of the outstanding shares of XPDB Common Stock, voting together as a single class, vote “FOR” the Charter Proposal.

Failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting, abstentions and broker non-votes will have the same effect as a vote “AGAINST” the Charter Proposal.

The Business Combination is conditioned upon the approval of the Charter Proposal, subject to the terms of the Merger Agreement. Notwithstanding the approval of the Charter Proposal, if the Business Combination is not consummated for any reason, the actions contemplated by the Charter Proposal will not be effected. The XPDB Board shall abandon the Charter Proposal in the event the Business Combination is not consummated.

A copy of the Proposed Charter, as will be in effect assuming approval of the Charter Proposal and upon consummation of the Business Combination and filing with the Secretary of State of the State of Delaware, is attached to this proxy statement/prospectus as Annex B.

The Sponsor and certain of XPDB’s directors, who collectively own as of the Record Date an aggregate of approximately 40% of the outstanding shares of XPDB Common Stock, have agreed to vote the Founder Shares and any Public Shares owned by them in favor of the Charter Proposal. See the section entitled “Other Agreements — Sponsor Support Agreement” for more information.

PROPOSAL NO. 3 — THE GOVERNANCE PROPOSAL

Overview

Our stockholders are being asked to vote on a separate proposal with respect to certain governance provisions in the Proposed Charter, which are separately being presented in accordance with SEC guidance and which will be voted upon on a non-binding advisory basis in the sub-proposals below. In the judgment of the XPDB Board, these provisions are necessary to adequately address the needs of the Post-Combination Company. Accordingly, regardless of the outcome of the non-binding advisory vote on these proposals, Montana and XPDB intend that the Proposed Charter in the form set forth on Annex B will take effect at consummation of the Business Combination, assuming adoption of the Charter Proposal.

If the Business Combination Proposal is not approved, the Governance Proposal will not be presented at the Special Meeting. The approval of the Governance Proposal requires the majority of the votes cast by the stockholders present in person (which would include presence at a virtual meeting) or represented by proxy at the Special Meeting.

Table of Contents

The Business Combination is not conditioned upon the approval of the Governance Proposal.

As discussed above, a vote to approve the Governance Proposal is an advisory vote, and therefore, is not binding on XPDB, Montana or their respective boards of directors. Accordingly, regardless of the outcome of the non-binding advisory vote, XPDB and Montana intend that the Proposed Charter, in the form set forth on Annex B and containing the provisions noted above, will take effect at consummation of the Business Combination, assuming adoption of the Charter Proposal.

The Sponsor and certain of XPDB’s directors, who collectively own as of the Record Date an aggregate of approximately % of the outstanding shares of XPDB Common Stock, have agreed to vote the Founder Shares and any Public Shares owned by them in favor of the Governance Proposal. See the section entitled “Other Agreements — Sponsor Support Agreement” for more information.

Recommendation of the XPDB Board

THE XPDB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE XPDB STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE GOVERNANCE PROPOSAL.

The existence of financial and personal interests of one or more of XPDB’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 XPDB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Governance Proposal. In addition, XPDB’s directors, executive officers and the Sponsor and its affiliates may have interests in the Business Combination that may conflict with your interests as a stockholder.

PROPOSAL NO. 4 — THE DIRECTOR ELECTION PROPOSAL

Overview

Assuming the Business Combination Proposal, the Charter Proposal, the Nasdaq Proposal, the Incentive Plan Proposal and the Employee Stock Purchase Plan Proposal are approved at the Special Meeting, stockholders are being asked to elect directors to the Post-Combination Company Board, effective upon the Closing, with each Class I director having a term that expires at the Post-Combination Company’s annual meeting of stockholders in 2024, each Class II director having a term that expires at the Post-Combination Company’s annual meeting of stockholders in 2025 and each Class III director having a term that expires at the Post-Combination Company’s annual meeting of stockholders in 2026, or, in each case, until their respective successors are duly elected and qualified, or until their earlier resignation, removal or death. The election of these directors is contingent upon approval of the Business Combination Proposal, the Charter Proposal, the Nasdaq Proposal, the Incentive Plan Proposal and the Employee Stock Purchase Plan Proposal.

The XPDB Board has nominated and to serve as the Class I directors, and to serve as the Class II directors and Patrick C. Eilers to serve as a Class III director. The following sets forth information regarding each nominee:

Patrick C. Eilers serves as XPDB’s Chief Executive Officer and is a member of the XPDB Board. Mr. Eilers is the founder and has served since 2019 as the Managing Partner of TEP, a private equity firm focused on the energy and power transition, in particular its impact on the electrical grid, with an expertise in (i) renewable energy, (ii) energy storage, technology, equipment and services, and (iii) transitional energy infrastructure. Mr. Eilers has over 20 years of investment experience focused on the energy & power transition. Mr. Eilers served as Chief Executive Officer and Director of Power & Digital Infrastructure Acquisition Corp. (“XPDI I”) from December 2020 until his resignation concurrently with the completion of XPDI I’s merger with Core Scientific Holding Co. (“Core Scientific”) in January 2022.

Vote Required for Approval

If the Business Combination Proposal is not approved, the Director Election Proposal will not be presented at the Special Meeting. If a quorum is present, directors are elected by a plurality of the votes cast by the holders of XPDB Class B Common Stock, voting as a separate class, present in person (which would include presence at a virtual meeting) or represented by proxy at the Special Meeting and entitled to vote thereon. This means that the director nominees who receive the most affirmative votes will be elected. Votes marked “FOR” a nominee will be counted in favor of that nominee. Proxies will have full discretion to cast votes for other persons in the event any nominee is unable to serve.

The Business Combination is conditioned upon the approval of the Director Election Proposal. Notwithstanding the approval of each of the director nominees to the Post-Combination Company Board in the Director Election Proposal, if the Business Combination is not consummated for any reason, the actions contemplated by the Director Election Proposal will not be effected. The XPDB Board shall abandon the Director Election Proposal in the event the Business Combination is not consummated.

Recommendation of the XPDB Board

THE XPDB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE XPDB STOCKHOLDERS VOTE “FOR” THE ELECTION OF EACH OF THE DIRECTOR NOMINEES TO THE BOARD OF DIRECTORS IN THE DIRECTOR ELECTION PROPOSAL.

The existence of financial and personal interests of one or more of XPDB’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 XPDB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Director Election Proposal. In addition, XPDB’s directors, executive officers and the Sponsor and its affiliates may have interests in the Business Combination that may conflict with your interests as a stockholder.

PROPOSAL NO. 5 — THE NASDAQ PROPOSAL

Overview

Immediately prior to and in connection with the Business Combination, we intended to effect (subject to customary terms and conditions, including the Closing) the issuance and/or sale of up to shares of Class A Common Stock and shares of Class B Common Stock to the holders of Montana’s capital stock pursuant to the Merger Agreement.

For more information, see the full text of the Merger Agreement, dated as of June 5, 2023, a copy of which is attached as Annex A. The discussion herein is qualified in its entirety by reference to the full text of the Merger Agreement.

Why XPDB Needs Stockholder Approval for Purposes of Nasdaq Listing Rule 5635

We are seeking stockholder approval in order to comply with Nasdaq Listing Rule 5635(a) and (b).

Under Nasdaq Listing Rule 5635(a), stockholder 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 such securities (or securities convertible into or exercisable for common stock); or (ii) the number of shares of common stock to be issued is or will be equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the stock or securities.

Under Nasdaq Listing Rule 5635(b), stockholder approval is required prior to the issuance of securities when the issuance or potential issuance will result in a “change of control” of the registrant. Although the Nasdaq has not adopted any rule on what constitutes a “change of control” for purposes of Rule 5635(b), the 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 common stock (or securities convertible into or exercisable for common stock) or voting power of an issuer could constitute a change of control.

As described above, XPDB will issue shares of Class A Common Stock to Montana Equityholders and upon the conversion of XPDB Class B Common Stock, in each case, as set forth in the Merger Agreement.

Stockholder approval of the Nasdaq Proposal is also a condition to the Closing under the Merger Agreement.

Vote Required for Approval

If the Business Combination Proposal is not approved, the Nasdaq Proposal will not be presented at the Special Meeting. The approval of the Nasdaq Proposal requires the affirmative vote of a majority of the votes cast by the stockholders present in person (which would include presence at a virtual meeting) or represented by proxy at the Special Meeting.

Failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting, abstentions and broker non-votes will have no effect on the Nasdaq Proposal.

The Business Combination is conditioned upon the approval of the Nasdaq Proposal, subject to the terms of the Merger Agreement. Notwithstanding the approval of the Nasdaq Proposal, if the Business Combination is not consummated for any reason, the actions contemplated by the Nasdaq Proposal will not be effected.

The Sponsor and certain of XPDB’s directors, who collectively own as of the Record Date an aggregate of approximately % of the outstanding shares of XPDB Common Stock, have agreed to vote the Founder Shares and any Public Shares owned by them in favor of the Nasdaq Proposal. See the section entitled “Other Agreements — Sponsor Support Agreement” for more information.

PROPOSAL NO. 6 — THE INCENTIVE PLAN PROPOSAL

Overview

As discussed in this proxy statement/prospectus, XPDB is asking its stockholders to approve the Montana Technologies Corporation 2023 Incentive Award Plan (the “Incentive Plan”), which provides for the issuance of equity-based awards to certain eligible service providers. The XPDB Board approved and adopted the Incentive Plan, subject to stockholder approval. If the XPDB stockholders approve this proposal, the Incentive Plan will become effective upon the consummation of the Business Combination.

The Incentive Plan is described in more detail below. A copy of the Incentive Plan is attached to this proxy statement/prospectus as Annex E.

Purpose of the Incentive Plan

The purpose of the Incentive Plan is to enhance the Post-Combination Company’s ability to attract, retain and motivate persons who make (or are expected to make) important contributions by providing these individuals with equity ownership opportunities and/or equity-linked compensatory opportunities. Equity awards and equity-linked compensatory opportunities are intended to motivate high levels of performance and align the interests of directors, employees and consultants with those of stockholders by giving directors, employees and consultants the perspective of an owner with an equity or equity-linked stake in the Post-Combination Company and providing a means of recognizing their contributions to the Post-Combination Company’s success. The XPDB Board believes that equity ownership opportunities and/or equity-linked compensatory opportunities are necessary to remain competitive in its industry and are essential to recruiting and retaining the highly qualified employees who help the Post-Combination Company meet its goals.

Summary of the Incentive Plan

The following summarizes the material terms of the Incentive Plan. This summary is qualified in its entirety by reference to the full text of the Incentive Plan.

Administration. The Post-Combination Company Board, or any committee or committees of officers of the Post-Combination Company to whom the Post-Combination Company Board delegates such power or authority (subject to limitations imposed under Section 16 of the Exchange Act and other applicable law and regulation), will serve as the plan administrator of the Incentive Plan. The plan administrator has full authority to take all actions and to make all determinations required or provided for under the Incentive Plan and any award granted thereunder. The plan administrator also has full authority to determine who may receive awards under the Incentive Plan, the type, terms, and conditions of an award, the number of shares of Class A Common Stock subject to the award or to which an award relates, and to make any other determination and take any other action that the plan administrator deems necessary or desirable for the administration of the Incentive Plan.

Share Reserve. The aggregate number of shares of Class A Common Stock that may be issued pursuant to awards granted under the Incentive Plan will be the sum of: (i) % of the fully-diluted shares of Class A Common Stock and Class B Common Stock as of the Closing; and (ii) an annual increase on January 1 of each calendar year (commencing with January 1, 2024 and ending on and including January 1, 2033) equal to a number of shares equal to % of the aggregate shares of Class A Common Stock and Class B Common Stock outstanding as of December 31 of the immediately preceding calendar year (or such lesser number of shares as is determined by the Post-Combination Company Board), subject to adjustment by the plan administrator in the event of certain changes in the Post-Combination Company’s corporate structure, as described below. The maximum number of shares that may be issued pursuant to the exercise of incentive stock options (“ISOs”), under the Incentive Plan will be shares of Class A Common Stock.

If an award (or part of an award) under the Incentive Plan is forfeited, expires, lapses or is terminated, is exchanged for or settled for cash, surrendered, repurchased or canceled, without having been fully exercised/settled or forfeited, in any case, in a manner that results in the Post-Combination Company acquiring the shares covered by the award (at a price no greater than the price paid by the participant for such shares) or that results in the Post-Combination Company not issuing shares under the award, any unused shares subject to such award will, as applicable, become or again be available for new grants under the Incentive Plan. In addition, shares tendered or withheld to satisfy the exercise or

Table of Contents

purchase price or tax withholding obligation for any award granted under the Incentive Plan will again be available for grants under the Incentive Plan. The payment of dividend equivalents in cash in conjunction with any awards under the Incentive Plan will not reduce the shares available for grant under the Incentive Plan.

Awards granted under the Incentive Plan in substitution for any equity or equity-based awards granted by an entity before such entity’s merger or consolidation with the Post-Combination Company or the Post-Combination Company’s acquisition of such entity’s property or equity securities will not reduce the shares available for grant under the Incentive Plan but will count against the maximum number of shares that may be issued upon the exercise of ISOs.

The Incentive Plan provides that the sum of any cash compensation and the aggregate grant date fair value (determined as of the date of the grant under Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor thereto) of all awards granted to a non-employee director as compensation for services as a non-employee director during any fiscal year may not exceed $500,000 (or, with respect to the first fiscal year of the Post-Combination Company during which a non-employee director first serves as a non-employee director, $1,000,000).

Eligibility. The Post-Combination Company’s directors, employees and consultants, and employees and consultants of the Post-Combination Company’s subsidiaries, will be eligible to receive awards under the Incentive Plan; however, ISOs may only be granted to employees of the Post-Combination Company or the Post-Combination Company’s parent or subsidiary corporations. Following the Closing, the Post-Combination Company is expected to have approximately directors, employees and consultants who will be eligible to receive awards under the Incentive Plan.

Types of Awards. The Incentive Plan allows for the grant of awards in the form of: (i) ISOs; (ii) non-qualified stock options (“NSOs”); (iii) SARs; (iv) restricted stock; (v) restricted stock units (“RSUs”); (vi) dividend equivalents; and (vii) other stock and cash-based awards.

• Stock Options and SARs. The plan administrator may determine the number of shares to be covered by each option and/or SAR, the exercise price and such other terms, conditions, and limitations, including the vesting, exercise, term and forfeiture provisions, applicable to each option and/or SAR as it deems necessary or advisable. Stock options provide for the purchase of shares of Class A Common Stock in the future at an exercise price set on the grant date. Options granted under the Incentive Plan may be either ISOs or NSOs. ISOs, in contrast to NSOs, may provide tax deferral beyond exercise and favorable capital gains tax treatment to their holders if certain holding period and other requirements of the Code are met. SARs entitle their holder, upon exercise, to receive from the Post-Combination Company an amount equal to the appreciation of the shares subject to the award between the grant date and the exercise date. The exercise price of an option or SAR is determined by the plan administrator at the time of grant but shall not be less than 100% of the fair market value of the underlying shares on the grant date, or in the case of ISOs granted to an employee who owns more than 10% of the Post-Combination Company, 110% of the fair market value of the underlying shares on the day of such grant. Stock options and SARs may have a maximum term of ten years, or, in the case of ISOs granted to an employee who owns more than 10% of the Post-Combination Company, five years from the date of grant. No dividends or dividend equivalents will be payable with respect to stock options or SARs.

• Restricted Stock. Restricted stock is an award of shares of Class A Common Stock that are subject to certain vesting conditions and other restrictions and that are nontransferable prior to vesting. The plan administrator may determine the terms and conditions of restricted stock awards, including the number of shares awarded, the purchase price, if any, to be paid by the recipient, the applicable vesting conditions, and any rights to acceleration thereof. The Incentive Plan provides that dividends payable with respect to restricted stock prior to the vesting of such restricted stock instead will be paid out to the participant only as and to the extent that the applicable vesting conditions of the underlying award are subsequently satisfied and the restricted stock vests. Dividends payable with respect to the portion of a restricted stock award that fails to vest will be forfeited.

Table of Contents

• RSUs. RSUs are contractual promises to deliver cash or shares of Class A Common Stock in the future, which may also remain forfeitable unless and until specified conditions are met. The terms and conditions applicable to RSUs are determined by the plan administrator, subject to the conditions and limitations contained in the Incentive Plan.

• Other Stock or Cash-Based Awards. Other stock or cash-based awards are awards of cash, fully vested shares of Class A Common Stock and other awards valued wholly or partially by reference to, or otherwise based on, shares of Class A Common Stock. Other stock or cash-based awards may be granted to participants and may also be available as a payment form in the settlement of other awards, as standalone payments and as payment in lieu of compensation to which a participant is otherwise entitled.

• Dividend Equivalents. Dividend equivalents represent the right to receive the equivalent value of dividends paid on shares of Class A Common Stock and may be granted alone or in tandem with awards other than stock options or SARs. Dividend equivalents are credited as of the dividend record dates during the period between the date an award is granted and the date such award vests, is exercised, is distributed or expires, as determined by the plan administrator. Under the Incentive Plan, dividend equivalents payable with respect to an award shall only be paid to a participant to the extent that the vesting conditions of the underlying award are subsequently satisfied and the award vests. Dividend equivalents payable with respect to the portion of the award that fails to vest will be forfeited.

Adjustments; Corporate Transactions. In the event of certain changes in the Post-Combination Company’s corporate structure, including any dividend, distribution, combination, merger, recapitalization or other corporate transaction, the plan administrator may make appropriate adjustments to the terms and conditions of outstanding awards under the Incentive Plan to prevent dilution or enlargement of the benefits or intended benefits under the Incentive Plan, to facilitate the transaction or event or to give effect to applicable changes in law or accounting standards. In addition, in the event of certain non-reciprocal transactions with the Post-Combination Company’s stockholders known as “equity restructurings,” the plan administrator will make equitable adjustments to the Incentive Plan and outstanding awards granted thereunder.

Effect of Non-Assumption in Change in Control. Unless otherwise determined by the plan administrator, in the event a change in control (as defined in the Incentive Plan) occurs and a participant’s award is not continued, converted, assumed or replaced by the Post-Combination Company or a successor entity with an award (which may include, without limitation, a cash-based award) with substantially the same value as and vesting terms that are no less favorable than those applicable to the underlying award, in each case, as of immediately prior to the change in control, and provided the participant remains in continuous service through such change in control, the award will become fully vested and exercisable, as applicable, and all forfeiture, repurchase and other restrictions on such award will lapse, in which case such award, to the extent in the money, will be cancelled upon the consummation of the change in control in exchange for the right to receive the consideration payable in the change in control.

Repricings. The plan administrator may, without shareholder approval, reduce the exercise price of any stock option or SAR, cancel any stock option or SAR with an exercise price that is less than the fair market value of a share of Post-Combination Company common stock in exchange for cash, or cancel any stock option or SAR in exchange for options, SARs or other awards with an exercise price per share that is less than the exercise price per share of the stock options or SARs for which such new stock options or SARs are exchanged.

Amendment and Termination. The Post-Combination Company Board may amend, suspend, or terminate the Incentive Plan at any time; provided that no amendment (other than an amendment that increases the number of shares reserved for issuance under the Incentive Plan, is permitted by the applicable award agreement or is made pursuant to applicable law) may materially and adversely affect any outstanding awards under the Incentive Plan without the affected participant’s consent. Stockholder approval will be required for any amendment to the Incentive Plan to increase the aggregate number of shares of Class A Common Stock that may be issued under the Incentive Plan (other than due to adjustments as a result of share dividends, reclassifications, share splits, consolidations or other similar corporate transactions), to the extent necessary to comply with applicable laws or for any amendment to increase the limitation on the sum of cash compensation and the aggregate fair value of awards granted to a non-employee director

Table of Contents

during any fiscal year. An ISO may not be granted under the Incentive Plan after ten (10) years from the earlier of the date the XPDB Board adopted the Incentive Plan or the date on which XPDB’s shareholders approve the Incentive Plan.

Foreign Participants, Clawback Provisions and Transferability. The plan administrator may modify award terms, establish subplans and/or adjust other terms and conditions of awards, subject to the share limits described above, in order to facilitate grants of awards subject to the laws and/or stock exchange rules of countries outside of the United States. All awards granted under the Incentive Plan will be subject to any Post-Combination Company clawback policy as set forth in such clawback policy or the applicable award agreement. Awards under the Incentive Plan are generally non-transferrable, except by will or the laws of descent and distribution, or, subject to the plan administrator’s consent, pursuant to a domestic relations order, and are generally exercisable only by the participant.

Material U.S. Federal Income Tax Consequences

The following is a general summary under current law of the principal United States federal income tax consequences related to awards under the Incentive Plan. This summary deals with the general United States federal income tax principles that apply and is provided only for general information. Some kinds of taxes, such as state, local and foreign income taxes and federal employment taxes, are not discussed. This summary is not intended as tax advice to participants, who should consult their own tax advisors.

Non-Qualified Stock Options. If an optionee is granted an NSO under the Incentive Plan, the optionee should not have taxable income on the grant of the option. Generally, the optionee should recognize ordinary income at the time of exercise in an amount equal to the fair market value of the shares acquired on the date of exercise, less the exercise price paid for the shares. The optionee’s basis in Class A Common Stock for purposes of determining gain or loss on a subsequent sale or disposition of such shares generally will be the fair market value of Class A Common Stock on the date the optionee exercises such option. Any subsequent gain or loss should be taxable as a long-term or short-term capital gain or loss. The Post-Combination Company or its subsidiaries or affiliates generally should be entitled to a federal income tax deduction at the time and for the same amount as the optionee recognizes ordinary income, subject to Code limitations.

Incentive Stock Options. A participant receiving ISOs should not recognize taxable income upon grant or at the time of exercise. However, the excess of the fair market value of the shares of Class A Common Stock received over the option exercise price is an item of tax preference income potentially subject to the alternative minimum tax. If stock acquired upon exercise of an ISO is held for a minimum of two years from the date of grant and one year from the date of exercise and otherwise satisfies the ISO requirements, the gain or loss (in an amount equal to the difference between the fair market value on the date of disposition and the exercise price) upon disposition of the stock should be treated as a long-term capital gain or loss, and the Post-Combination Company should not be entitled to any deduction. If the holding period requirements are not met, the ISO should be treated as one that does not meet the requirements of the Code for ISOs and the participant should recognize ordinary income at the time of the disposition equal to the excess of the amount realized over the exercise price, but not more than the excess of the fair market value of the shares on the date the ISO is exercised over the exercise price, with any remaining gain or loss being treated as capital gain or capital loss. The Post-Combination Company and its subsidiaries or affiliates generally are not entitled to a federal income tax deduction upon either the exercise of an ISO or upon disposition of the shares acquired pursuant to such exercise, except to the extent that the participant recognizes ordinary income on disposition of the shares, subject to Code limitations.

Restricted Stock Units. A participant generally will not recognize taxable income upon grant of restricted stock units. When cash or shares of common stock are delivered under the terms of the award, the participant should recognize ordinary income equal to the cash payment or the fair market value of the shares delivered, as the case may be, less any amount (if any) paid by the participant for such shares, and the Post-Combination Company and its subsidiaries or affiliates generally should be entitled to a corresponding deduction at that time, subject to Code limitations.

Other Awards. The current federal income tax consequences of other awards authorized under the Incentive Plan generally follow certain basic patterns: SARs are taxed and deductible in substantially the same manner as NSOs; nontransferable restricted stock subject to a substantial risk of forfeiture results in income recognition equal to the excess of the fair market value over the price paid, if any, only at the time the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant through a Code Section 83(b) election); dividend equivalents and

Table of Contents

other stock or cash-based awards are generally subject to tax at the time of payment. The Post-Combination Company and its subsidiaries or affiliates generally should be entitled to a federal income tax deduction at the time and for the same amount as the optionee recognizes ordinary income, subject to Code limitations.

Section 409A of the Code

Certain types of awards under the Incentive Plan may constitute, or provide for, a deferral of compensation subject to Section 409A of the Code. Unless certain requirements set forth in Section 409A of the Code are complied with, holders of such awards may be taxed earlier than would otherwise be the case (e.g., at the time of vesting instead of the time of payment) and may be subject to an additional 20% penalty tax (and, potentially, certain interest, penalties and additional state taxes). To the extent applicable, the Incentive Plan and awards granted under the Incentive Plan are intended to be structured and interpreted in a manner intended to either comply with or be exempt from the requirements of Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance that may be issued under Section 409A of the Code. To the extent determined necessary or appropriate by the plan administrator, the Incentive Plan and applicable award agreements may be amended to further comply with Section 409A of the Code or to exempt the applicable awards from Section 409A of the Code.

Plan Benefits

The benefits or amounts that may be received or allocated to participants under the Incentive Plan will be determined at the discretion of the plan administrator and are not currently determinable. The closing price of the Class A Common Stock as of June 30, 2023 was $10.40 per share.

Vote Required for Approval

The Business Combination is conditioned on the approval and adoption of the Incentive Plan Proposal. Therefore, if the Incentive Plan Proposal is not approved, the Business Combination will not be consummated.

If the Business Combination Proposal is not approved, the Incentive Plan Proposal will not be presented at the Special Meeting. The approval of the Incentive Plan Proposal, under Delaware law, requires the affirmative vote of a majority of the XPDB Common Stock represented in person (which would include presence at a virtual meeting) or by proxy and entitled to vote thereon and who vote at the Special Meeting. Abstentions while considered present for the purposes of establishing a quorum, will not count as votes cast at the Special Meeting.

Recommendation of the XPDB Board

THE XPDB BOARD RECOMMENDS THAT THE XPDB STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE INCENTIVE PLAN PROPOSAL.

The existence of financial and personal interests of one or more of XPDB’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 XPDB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Incentive Plan Proposal. In addition, XPDB’s directors, executive officers and the Sponsor and its affiliates may have interests in the Business Combination that may conflict with your interests as a stockholder. See the section titled “The Business Combination — Interests of the Sponsor and XPDB’s Directors and Executive Officers in the Business Combination” for a further discussion of these considerations.

PROPOSAL NO. 7 — THE EMPLOYEE STOCK PURCHASE PLAN PROPOSAL

Overview

As discussed in this proxy statement/prospectus, XPDB is asking its stockholders to approve the Montana Technologies Corporation 2023 Employee Stock Purchase Plan (the “ESPP”). The XPDB Board approved and adopted the ESPP, subject to shareholder approval. If the XPDB stockholders approve this proposal, the ESPP will become effective upon the consummation of the Business Combination.

The ESPP is described in more detail below. A copy of the ESPP is attached to this proxy statement/prospectus as Annex F.

Purpose of the ESPP

The purpose of the ESPP is to provide the Post-Combination Company’s and its participating subsidiaries’ employees with the opportunity to purchase shares of Class A Common Stock through accumulated payroll deductions. The Post-Combination Company believes that the ESPP is a key factor in retaining its existing employees, recruiting and retaining new employees and aligning the interests of its employees with those of the Post-Combination Company’s stockholders.

Summary of the ESPP

The following summarizes the material terms of the ESPP. This summary is qualified in its entirety by reference to the full text of the ESPP.

The ESPP is comprised of two distinct components in order to provide increased flexibility to grant purchase rights under the ESPP to U.S. and any non-U.S. employees. Specifically, the ESPP authorizes (i) the grant of purchase rights to U.S. employees that are intended to qualify for favorable U.S. federal tax treatment under Section 423 of the Code (the “Section 423 Component”) and (ii) the grant of purchase rights that are not intended to be tax-qualified under Section 423 of the Code to facilitate participation for any employees located outside of the United States who do not benefit from favorable U.S. tax treatment and to provide flexibility to comply with non-U.S. law and other considerations (the “Non-Section 423 Component”). Where possible under local law and custom, the Post-Combination Company expects that the Non-Section 423 Component generally will be operated and administered on terms and conditions similar to the Section 423 Component.

Administration. The Compensation Committee of the Post-Combination Company Board, or any other committee to whom the Post-Combination Company Board delegates such power or authority, will serve as the administrator of the ESPP. The plan administrator may delegate administrative tasks under the ESPP to agents or employees to assist in the administration of the ESPP. Subject to the terms and conditions of the ESPP, the plan administrator has the authority to determine when rights to purchase shares will be offered and the provisions of each offering under the ESPP, to determine which subsidiaries will participate as “designated subsidiaries” in the ESPP (including in the Non-Section 423 and the Section 423 Components), and to make all other determinations and to take all other actions necessary or advisable for the administration of the ESPP. The plan administrator is also authorized to establish, amend or revoke rules relating to administration of the ESPP and to adopt annexes or sub-plans that apply to certain participating subsidiaries or jurisdictions.

Share Reserve. The aggregate number of shares of Class A Common Stock that may be issued pursuant to rights granted under the ESPP will equal % of the number of shares of the Post-Combination Company’s Class A and Class B Common Stock outstanding at the Closing. In addition, on the first day of each fiscal year beginning on January 1, 2024 and ending on (and including) January 1, 2033, the number of shares available for issuance under the ESPP will be increased by a number of shares equal to the lesser of (i) % of the outstanding shares of Class A and Class B Common Stock on the final day of the immediately preceding calendar year, and (ii) such smaller number of shares as determined by the Post-Combination Company Board. If any right granted under the ESPP terminates for any reason without having been exercised, the shares subject thereto that are not purchased under such right will again be available for issuance under the ESPP. Notwithstanding the foregoing, no more than shares of Class A Common Stock may be issued under the Section 423 Component of the ESPP.

Table of Contents

Eligible Employees. Employees who are employed by the Post-Combination Company or one of its designated subsidiaries on the first trading day of the offering period, or the enrollment date, are generally eligible to participate in the ESPP for a given offering. However, an employee who owns (or is deemed to own through attribution) 5% or more of the combined voting power or value of all classes of the Post-Combination Company or one of its subsidiaries’ stock will not be allowed to participate in the ESPP (unless otherwise required under applicable law). In addition, the plan administrator may provide that an employee may not be eligible to participate in an offering under the Section 423 Component if the employee is a citizen or resident of a non-U.S. jurisdiction and the grant of a right to purchase shares would be prohibited under applicable law or would cause the Section 423 Component (or any offering thereunder) to violate the requirements of Section 423 of the Code. Additionally, the plan administrator may provide that certain highly compensated, seasonal and/or part-time employees may not be eligible to participate in an offering or, with respect to offerings under the Non-Section 423 Component, that only certain employees are eligible to participate in such offerings (regardless of the foregoing rules).

Following the Closing, the Post-Combination Company is expected to have approximately employees who are eligible to participate in the ESPP.

Participation. Eligible employees may become participants in the ESPP for an offering period by completing a Subscription Agreement prior to the enrollment date of the applicable offering period, which will designate a whole percentage of the eligible employee’s compensation to be withheld as payroll deductions under the ESPP during the offering period.

Offerings; Purchase Periods

• Offerings; Purchase Periods. Under the ESPP, participants are offered the right to purchase shares of Class A Common Stock at a discount during a series of offering periods. The length of the offering periods under the ESPP will be determined by the plan administrator and may be up to twenty-seven (27) months long. Accumulated payroll deductions will be used to purchase shares of Class A Common Stock on each purchase date during an offering period. The number of purchase periods within, and purchase dates during, each offering will be established by the plan administrator, but in no event will any purchase period exceed six (6) months. Offering periods under the ESPP will commence when determined by the plan administrator. The plan administrator may, in its discretion, modify the terms of future offerings.

• Enrollment and Contributions. The ESPP permits participants to purchase Class A Common Stock through payroll deductions of a whole percentage of their eligible compensation, which may not be less than 1% and may be up to a maximum percentage of such compensation determined by the plan administrator (which, in the absence of a contrary designation, will be 15% of eligible compensation). The plan administrator will establish a maximum number of shares that may be purchased by a participant during any offering period or purchase period, which, in the absence of a contrary designation, will be shares of Class A Common Stock for an offering period and shares of Class A Common Stock for a purchase period. In addition, a participant may not, with respect to the Section 423 Component, subscribe for more than $25,000 worth of shares under the ESPP per calendar year in which such rights to purchase stock are outstanding (considered together with any other ESPP maintained by the Post-Combination Company or certain parent or subsidiary entities) based on the fair market value of the shares at the time the purchase right is granted.

• Purchase Rights. On the first trading day of each offering period, each participant will automatically be granted an option to purchase shares of Class A Common Stock. Unless a participant has previously withdrawn his or her participation in, or has otherwise become ineligible to participate in, the ESPP prior to any applicable purchase date, the option will be exercised on the applicable purchase date(s) during the offering period to the extent of the payroll deductions accumulated during the offering period. The participant will purchase the maximum number of whole shares of Class A Common Stock that his or her accumulated payroll deductions will buy at the purchase price, subject to the participation limitations described above, and any fractional shares will be credited to the participant’s account and carried forward and applied toward the purchase of whole shares on the next purchase date.

Table of Contents

• Purchase Price. The purchase price for each offering period will be designated by the plan administrator in the applicable offering document (which purchase price, for purposes of the Section 423 Component, will not be less than 85% of the closing trading price of a share of Class A Common Stock on the enrollment date or purchase date of the applicable offering period, whichever is lower) or, in the absence of a designation by the plan administrator, the purchase price will be the lower of 85% of the closing trading price per share of XPDB Common Stock on the enrollment date of the applicable offering period or 85% of the closing trading price per share on the applicable purchase date, which will be the last trading day of each purchase period.

• Payroll Deduction Changes; Withdrawals; Terminations of Employment. Unless otherwise provided for in an offering document, a participant may increase or decrease the percentage of compensation designated in the participant’s Subscription Agreement or suspend his or her payroll deductions, in either case, once during any offering period. In addition, a participant may withdraw his or her participation from the ESPP at any time by submitting written notice to the Post-Combination Company at least two weeks prior to the end of the then-current purchase period for the offering in which such participant is enrolled. Upon any withdrawal, the participant will receive a refund of the participant’s account balance in cash, and his or her payroll deductions shall cease. Participation in the ESPP ends automatically upon a participant’s termination of employment.

Transfer Restrictions. A participant may not transfer (other than by will or the laws of descent and distribution) any right granted under the ESPP and, during a participant’s lifetime, purchase rights granted under the ESPP shall be exercisable only by such participant.

Adjustments; Changes in Capitalization. In the event of certain transactions or events affecting Class A Common Stock, such as any stock dividend or other distribution, change in control, reorganization, merger, consolidation or other corporate transaction, the ESPP administrator will make equitable adjustments to the ESPP and outstanding rights. In addition, in the event of the foregoing transactions or events or certain significant transactions, including a change in control or change in applicable law or accounting principles, the ESPP administrator may, in order to prevent the dilution or enlargement of intended benefits under the ESPP or facilitate or give effect to such transactions, events or changes, provide for one or more of the following: (i) either the replacement of outstanding rights with other rights or property or termination of outstanding rights in exchange for cash, (ii) the assumption or substitution of outstanding rights by the successor or survivor corporation or parent or subsidiary thereof, (iii) the adjustment in the number and type of shares of stock subject to outstanding rights, (iv) the use of participants’ accumulated payroll deductions to purchase shares of Class A Common Stock on a new purchase date prior to the next scheduled purchase date and termination of any rights under ongoing offering periods or (v) the termination of all outstanding rights.

Amendment and Termination. The plan administrator may amend, suspend or terminate the ESPP at any time, subject to stockholder approval to increase the number (or change the type) of securities that may be issued under the ESPP or as otherwise required under Section 423 of the Code.

Material U.S. Federal Income Tax Consequences

The following is a general summary under current law of the principal United States federal income tax consequences related to participation in the ESPP. This summary deals with the general federal income tax principles that apply and is provided only for general information. Some kinds of taxes, such as state, local and foreign income taxes and federal employment taxes, are not discussed. This summary is not intended as tax advice to participants, who should consult their own tax advisors.

Section 423 Component. The Section 423 Component of the ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Code.

For federal income tax purposes, a participant in the Section 423 Component of the ESPP generally will not recognize taxable income on the grant or exercise of an option under the ESPP, nor will the Post-Combination Company be entitled to any deduction at that time.

Table of Contents

If shares acquired upon exercise of an option acquired under the Section 423 Component of the ESPP are held for a minimum of two (2) years from the date of grant and one (1) year from the date of exercise, the participant (or the participant’s estate) will recognize ordinary income at the time of disposition of the shares measured as the lesser of (i) the excess of the fair market value of the shares at the time of such sale or disposition (or death) over the purchase price or (ii) the excess of the fair market value of the shares on the date the option was granted over the purchase price. Any additional gain will be treated as long-term capital gain.

If the holding period requirements are not met, the participant will recognize ordinary income at the time of the disposition equal to the excess of the fair market value of the shares on the date the option is exercised over the purchase price, with any remaining gain or loss being treated as capital gain or capital loss. However, if the holding period requirements are not met and the amount realized at the time of disposition is less than the fair market value of the shares at the time of exercise, the participant will recognize ordinary income to the extent of the excess of the fair market value of such shares on the date the option was exercised over the purchase price for such shares, and a capital loss to the extent the fair market value of such shares on the exercise date exceeds the amount realized upon disposition.

The Post-Combination Company or its subsidiaries or affiliates generally are not entitled to a federal income tax deduction upon either the exercise of an option or upon disposition of the shares acquired pursuant to such exercise, except to the extent that the participant recognizes ordinary income on disposition of the shares, subject to Code limitations.

Non-Section 423 Component. The Non-Section 423 Component of the ESPP is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Code. Accordingly, certain tax benefits available to participants in a Section 423 plan are not available under the Non-Section 423 Component of the ESPP.

For federal income tax purposes, a participant in the Non-Section 423 Component of the ESPP generally will not recognize taxable income on the grant of an option under the ESPP, nor will the Post-Combination Company be entitled to any deduction at that time. Upon the exercise of an ESPP option, a participant will recognize ordinary income, and the Post-Combination Company will be entitled to a corresponding deduction, in an amount equal to the difference between the fair market value of the shares of Class A Common Stock on the exercise date and the purchase price paid for the shares. A participant’s basis in shares of Class A Common Stock received on exercise, for purposes of determining the participant’s gain or loss on subsequent disposition of such shares of the Post-Combination Company’s common stock, generally, will be the fair market value of the shares of Class A Common Stock on the date the participant exercises his or her option.

Upon the subsequent sale of the shares acquired upon the exercise of an option acquired under the Non-Section 423 Component of the ESPP, the participant will recognize capital gain or loss (long-term or short-term, depending on how long the shares were held following the date they were purchased by the participant prior to disposing of them).

The Post-Combination Company or its subsidiaries or affiliates will generally be entitled to a federal income tax deduction upon the exercise of the option to the extent that the participant recognizes ordinary income, subject to Code limitations.

Plan Benefits

Because the number of shares that may be purchased under the ESPP will depend on each employee’s voluntary election to participate and on the fair market value of our common stock at various future dates, the actual number of shares that may be purchased by any individual under the ESPP cannot currently be determined.

Vote Required for Approval

If the Business Combination Proposal is not approved, the Employee Stock Purchase Plan Proposal will not be presented at the Special Meeting. The Employee Stock Purchase Plan Proposal, under Delaware law, requires the affirmative vote of a majority of the XPDB Common Stock represented in person (which would include presence at a virtual meeting) or by proxy and entitled to vote thereon and who vote at the Special Meeting. Abstentions while considered present for the purposes of establishing a quorum, will not count as votes cast at the Special Meeting.

Table of Contents

The Business Combination is conditioned on the approval and adoption of the Employee Stock Purchase Plan Proposal. Therefore, if the Employee Stock Purchase Plan Proposal is not approved, the Business Combination will not be consummated.

Recommendation of the XPDB Board

THE XPDB BOARD UNANIMOUSLY RECOMMENDS THAT THE XPDB STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE EMPLOYEE STOCK PURCHASE PLAN PROPOSAL.

The existence of financial and personal interests of one or more of XPDB’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 XPDB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Employee Stock Purchase Plan Proposal. In addition, XPDB’s directors, executive officers and the Sponsor and its affiliates may have interests in the Business Combination that may conflict with your interests as a shareholder. See the section titled “The Business Combination — Interests of the Sponsor and XPDB’s Directors and Executive Officers in the Business Combination” for a further discussion of these considerations.

PROPOSAL NO. 8 — THE ADJOURNMENT PROPOSAL

The Adjournment Proposal, if adopted, will allow the XPDB Board to adjourn the Special Meeting to a later date or dates, if necessary, to permit further solicitation of proxies if, based upon the tabulated vote at the time of the Special Meeting, there are not sufficient votes to approve the Business Combination Proposal, the Charter Proposal, the Director Election Proposal, the Nasdaq Proposal, the Incentive Plan Proposal or the Employee Stock Purchase Plan Proposal. In no event will the XPDB Board adjourn the Special Meeting or consummate the Business Combination beyond the date by which it may properly do so under the Existing Charter and Delaware law.

Consequences if the Adjournment Proposal is Not Approved

If the Adjournment Proposal is not approved by stockholders, the XPDB Board may not be able to adjourn the Special Meeting to a later date in the event that there are insufficient votes for the approval of the Business Combination Proposal, the Charter Proposal, the Governance Proposal, the Director Election Proposal, the Nasdaq Proposal, the Incentive Plan Proposal or the Employee Stock Purchase Plan Proposal, or we determine that one or more of the closing conditions under the Merger Agreement is not satisfied or waived. If XPDB does not consummate the Business Combination and fails to complete an initial business combination by December 14, 2023 or such further extended date as determined by the XPDB Board in accordance with the Existing Charter (subject to the requirements of law), XPDB will be required to dissolve and liquidate its Trust Account by returning the then remaining funds in such account to its XPDB Public Stockholders.

Vote Required for Approval

The approval of the Adjournment Proposal requires the majority of the votes cast by the stockholders present in person (which would include presence at a virtual meeting) or represented by proxy at the Special Meeting. The Adjournment Proposal is not conditioned upon the approval of any other proposal set forth in this proxy statement/prospectus.

The Business Combination is not conditioned upon the approval of the Adjournment Proposal.

The Sponsor and certain of XPDB’s directors, who collectively own as of the Record Date an aggregate of approximately % of the outstanding shares of XPDB’s Class A Common Stock, have agreed to vote the Founder Shares and any Public Shares owned by them in favor of the Adjournment Proposal, if presented. See the section entitled “Other Agreements — Sponsor Support Agreement” for more information.

Recommendation of the XPDB Board

THE XPDB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE XPDB STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE ADJOURNMENT PROPOSAL.

The existence of financial and personal interests of one or more of XPDB’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 XPDB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Adjournment Proposal. In addition, XPDB’s directors, executive officers and the Sponsor and its affiliates may have interests in the Business Combination that may conflict with your interests as a stockholder. See the section titled “The Business Combination — Interests of the Sponsor and XPDB’s Directors and Executive Officers in the Business Combination” for a further discussion of these considerations.

INFORMATION ABOUT XPDB

In this section “we,” “us,” “our” or the “Company” refer to XPDB prior to the Business Combination and to the Post-Combination Company following the Business Combination.

Introduction

We are a blank check company incorporated as a Delaware corporation and formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses, which we refer to throughout this proxy statement/prospectus as our initial business combination. We are an early stage and emerging growth company and, as such, we are subject to all of the risks associated with early stage and emerging growth companies.

Our Sponsor, formed by TEP and XMS, brings together experts in the renewable and transition power, equipment, services, data center, digital asset mining and financial advisory sectors. Representatives from the three firms with deep and complementary skills have come together to pursue these opportunities created by the electrical power grid transition.

• TEP is a private equity fund focused on renewable and transition energy infrastructure. Its leadership team has over 20 years of investment experience and has invested approximately $1.1 billion, including approximately $900 million directly, in the renewable and transition power verticals.

• XMS is a newly formed limited liability company owned by professionals of XMS Capital. XMS Capital, founded in 2006, is a global independent financial services firm providing investment banking, asset management and merchant banking services to a wide range of clients. It has offices in Chicago, London and Boston. The XMS Capital value proposition is characterized by Involvement Banking™, a service approach which goes beyond transaction-oriented investment banking and focuses on delivering objective, value-added advice and custom-tailored solutions to help clients achieve their strategic goals. Its track record of consistent value creation for its clients is attributable to its ability to provide turnkey access to comprehensive, independent mergers and acquisitions, strategic advisory, financial restructuring, capital structure advisory and private capital advisory expertise.

Company History

On March 30, 2021, the Sponsor purchased 7,187,500 Founder Shares for an aggregate purchase price of $25,000, or approximately $0.004 per share. Prior to the initial investment in the Company of $25,000 by our Sponsor, the Company had no assets, tangible or intangible. The per share price of the Founder Shares was determined by dividing the amount of cash contributed to the Company by the number of Founder Shares issued. The number of Founder Shares issued was determined based on the expectation that the Founder Shares would represent 20% of the outstanding shares of XPDB Common Stock upon completion of the XPDB IPO.

The registration statement for the XPDB IPO was declared effective on December 9, 2021. On December 14, 2021, we consummated the XPDB IPO of 28,750,000 units, with each unit consisting of one share of XPDB Class A Common Stock and one-half of one redeemable warrant. Each whole XPDB public warrant entitles the holder thereof to purchase one share of XPDB Class A Common Stock at a price of $11.50 per share, subject to certain adjustments. The units were sold at a price of $10.00 per unit, which included the exercise of the underwriters’ option to purchase an additional 3,750,000 units at the XPDB IPO price to cover over-allotments, generating gross proceeds to us of $287,500,000.

Simultaneously with the consummation of the XPDB IPO, we consummated the Private Placement of an aggregate of 11,125,000 Private Placement Warrants to our Sponsor and the Anchor Investors at a price of $1.00 per Private Placement Warrant, generating total proceeds of approximately $11,125,000. Of the gross proceeds received from the XPDB IPO and the Private Placement Warrants, approximately $290.4 million was placed into the Trust Account.

On January 28, 2022, we announced that, commencing January 31, 2022, holders of the units may elect to separately trade the shares of XPDB Class A Common Stock and the warrants included in the units. Those units not separated continued to trade on the Nasdaq under the symbol “XPDBU” and the shares of XPDB Class A Common Stock and warrants that were separated trade under the symbols “XPDB” and “XPDBW,” respectively. No fractional warrants were issued upon separation of the units and only whole warrants trade.

Table of Contents

In connection with the Extension Special Meeting, holders of 18,141,822 Public Shares exercised their right to redeem their shares for cash at a redemption price of approximately $10.37 per share. As a result, approximately $188,132,132 was removed from the Trust Account to pay such holders and 10,608,178 Public Shares remained outstanding.

Redemption Rights for Holders of Public Shares

We are providing our XPDB Public Stockholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of the Business Combination at a per share price, payable in cash, equal to (i) the aggregate amount then on deposit in the Trust Account as of two business days prior to the Closing, including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes, divided by (ii) the number of then outstanding Public Shares, subject to the limitations described herein. The amount in the Trust Account as of the Record Date was approximately $ per Public Share. The per share amount we will distribute to stockholders who properly redeem their shares will not be reduced by the deferred underwriting commissions we will pay to the remaining underwriter or another FINRA member. There will be no redemption rights upon the completion of the Business Combination with respect to our warrants. The redemption rights will include the requirement that any beneficial owner on whose behalf a redemption right is being exercised must identify itself in order to validly redeem its shares. Our Sponsor, officers and directors have entered into a letter agreement with us pursuant to which they have agreed to waive their redemption rights with respect to any Founder Shares they hold and any Public Shares they may acquire in connection with the completion of the Business Combination (which waiver was provided in connection with the XPDB IPO and without any separate consideration paid in connection with providing such waiver).

Limitation on Redemption Rights

Notwithstanding the foregoing redemption rights, in connection with the stockholder approval of the Business Combination, if we do not conduct redemptions pursuant to the tender offer rules, our Existing Charter provides that a holder of the Public Shares, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption rights with respect to more than an aggregate of 15% of the Public Shares without prior consent, which we refer to as the “15% threshold.” Accordingly, all Public Shares in excess of the 15% threshold beneficially owned by an XPDB Public Stockholder or group will not be redeemed for cash.

We believe this restriction will discourage stockholders from accumulating large blocks of shares, and subsequent attempts by such holders to use their ability to exercise their redemption rights against the Business Combination as a means to force us or our management to purchase their shares at a significant premium to the then-current market price or on other undesirable terms. Absent this provision, an XPDB Public Stockholder holding more than an aggregate of 15% of the Public Shares could threaten to exercise its redemption rights against the Business Combination if such holder’s shares are not purchased by us, our Sponsor or our management at a premium to the then-current market price or on other undesirable terms. By limiting our stockholders’ ability to redeem no more than 15% of the Public Shares, we believe we will limit the ability of a small group of stockholders to unreasonably attempt to block our ability to complete the Business Combination. However, we will not be restricting our stockholders’ ability to vote all of their shares (including such shares in excess of the 15% threshold) for or against the Business Combination.

Submission of Business Combination to a Stockholder Vote

The Special Meeting to which this filing relates is to solicit your approval of the Business Combination. XPDB Public Stockholders are not required to vote against the Business Combination in order to exercise their redemption rights. If the Business Combination is not completed, then XPDB Public Stockholders who elected to exercise their redemption rights will not be entitled to receive such payments. Our Sponsor and certain of our directors have agreed to vote their Founder Shares and any Public Shares purchased during or after the XPDB IPO in favor of approving the Business Combination.

Permitted Purchases of Our Securities

In connection with the stockholder approval of the Business Combination, unless we conduct redemptions pursuant to the tender offer rules, our Sponsor, directors, executive officers, advisors or their affiliates may purchase shares or XPDB public warrants in privately negotiated transactions or in the open market either prior to or following

101

Table of Contents

the completion of the Business Combination. There is no limit on the number of shares our Sponsor, directors, officers, advisors or their affiliates may purchase in such transactions, subject to compliance with applicable law and Nasdaq rules. 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 shares or XPDB public warrants in such transactions. If they engage in such transactions, they will be restricted from making any such purchases when they are in possession of any material non-public information not disclosed to the seller or if such purchases are prohibited by Regulation M under the Exchange Act.

In the event that our Sponsor, directors, officers, advisors or their affiliates purchase shares in privately negotiated transactions from XPDB Public Stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. We do not currently anticipate that such purchases, if any, would constitute a tender offer subject to the tender offer rules under the Exchange Act or a going-private transaction subject to the going-private rules under the Exchange Act; however, if the purchasers determine at the time of any such purchases that the purchases are subject to such rules, the purchasers will comply with such rules.

The purpose of any such purchases of shares could be to vote such shares in favor of the Business Combination and thereby increase the likelihood of obtaining stockholder approval of the Business Combination. The purpose of any such purchases of XPDB public warrants could be to reduce the number of XPDB public warrants outstanding. Any such purchases of our securities may result in the completion of the Business Combination that may not otherwise have been possible.

In addition, if such purchases are made, the public “float” of the XPDB Class A Common Stock or XPDB public warrants may be reduced and the number of beneficial holders of our securities may be reduced, which may make it difficult to maintain or obtain the quotation, listing or trading of our securities on a national securities exchange.

Our Sponsor, officers, directors and/or their affiliates anticipate that they may identify the stockholders with whom our Sponsor, officers, directors or their affiliates may pursue privately negotiated purchases by either the stockholders contacting us directly or by our receipt of redemption requests submitted by stockholders (in the case of XPDB Class A Common Stock) following our mailing of proxy materials in connection with the Business Combination. To the extent that our Sponsor, officers, directors, advisors or their affiliates enter into a private purchase, they would identify and contact only potential selling stockholders who have expressed their election to redeem their shares for a pro rata share of the Trust Account or vote against the Business Combination, whether or not such stockholder has already submitted a proxy with respect to the Business Combination, but only if such shares have not already been voted at the Special Meeting. Our Sponsor, executive officers, directors, advisors or any of their affiliates will select which stockholders to purchase shares from based on a negotiated price and number of shares and any other factors that they may deem relevant, and will only purchase shares if such purchases comply with Regulation M under the Exchange Act and the other federal securities laws. Our Sponsor, officers, directors and/or their affiliates will be restricted from making purchases of shares if the purchases would violate Section 9(a)(2) of, or Rule 10b-5 under, the Exchange Act. We expect any such purchases will be reported pursuant to Section 13 and Section 16 of the Exchange Act to the extent such purchases are subject to such reporting requirements.

Redemption of Public Shares and Liquidation if no Business Combination

Our Existing Charter provides that we will have until the end of the Completion Window to complete a business combination. If we are unable to complete a business combination by the end of the Completion Window, we will: (i) cease all operations except for the purpose of winding up, (ii) 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, equal to the aggregate amount then on deposit in the Trust Account, including interest (less amounts released to us to pay our taxes 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 XPDB Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and the XPDB Board, dissolve and liquidate, subject, in each case, to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete the Business Combination within the Completion Window.

102

Table of Contents

Pursuant to a letter agreement with us, our Sponsor, officers and directors have waived their rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by them if we fail to complete the Business Combination by the end of the Completion Window. However, if our Sponsor, officers or directors acquire new Public Shares, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if we fail to complete the Business Combination by the end of the Completion Window. For discussion of any such transactions please refer to the section entitled “Certain Relationships and Related Party Transactions.”

Pursuant to a letter agreement with us, our Sponsor, officers and directors have agreed, that they will not propose any amendment to our Existing Charter that would modify the substance or timing of our obligation to redeem 100% of our Public Shares if we do not complete the Business Combination by the end of the Completion Window, unless we provide our XPDB Public Stockholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per share price, payable in cash, equal to (i) 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 us to pay our taxes or other fees divided by (ii) the number of then outstanding Public Shares.

We expect that all costs and expenses associated with implementing our plan of dissolution, as well as payments to any creditors, will be funded from amounts remaining out of the approximately $494,804 of proceeds held outside the Trust Account (as of June 30, 2023), although there is no assurance 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 our plan of dissolution, to the extent that there is any interest accrued in the Trust Account not required to pay taxes on interest income earned on the Trust Account balance, we may request the trustee to release to us an additional amount of up to $100,000 of such accrued interest to pay those costs and expenses.

If we were to expend all of the remaining net proceeds of the XPDB IPO and the sale of the Private Placement Warrants, other than the proceeds not deposited in the Trust Account, and without taking into account interest, if any, earned on the Trust Account and any tax payments of expenses for the dissolution of the trust, the per share redemption amount received by stockholders upon our dissolution would be approximately $10.37, based on the balance of the Trust Account as of June 30, 2023. The proceeds deposited in the Trust Account could, however, become subject to the claims of our creditors which would have higher priority than the claims of our XPDB Public Stockholders. There is no assurance that the actual per share redemption amount received by stockholders will not be substantially less than $10.37. Under Section 281(b) of the DGCL, our plan of dissolution must provide for all claims against us to be paid in full or make provision for payments to be made in full, as applicable, if there are sufficient assets. These claims must be paid or provided for before we make any distribution of our remaining assets to our stockholders. While we intend to pay such amounts, if any, there is no assurance that we will have funds sufficient to pay or provide for all creditors’ claims.

Although we have sought and will continue to seek to have all vendors, service providers, prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest and claim of any kind in or to any monies held in the Trust Account for the benefit of our XPDB Public Stockholders, 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 our 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, our management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to us than any alternative. Examples of possible instances where we 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 connection with the Business Combination, we may potentially make a cash payment in an aggregate amount of up to $3,000,000 to XMS Capital, TEP or their respective affiliates for any financial advisory, placement agency or other similar investment banking or consulting services that XMS Capital, TEP or their respective affiliates may provide to us in connection with the Business Combination, and may reimburse to XMS Capital, TEP or their respective affiliates for any out-of-pocket expenses incurred by it in connection with the performance of such services. Marcum LLP, our independent registered public accounting firm, will not execute an agreement with us waiving such claims to the monies held in the Trust Account.

103

Table of Contents

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 us and will not seek recourse against the Trust Account for any reason. In order to protect the amounts held in the Trust Account, our Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party for services rendered or products sold to us, or a prospective target business with which we have discussed entering 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) $10.10 per Public Share or (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 $10.10 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 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 our indemnity of the underwriters of the XPDB IPO against certain liabilities, including liabilities under the Securities Act. However, we have not asked our Sponsor to reserve for such indemnification obligations, nor have we independently verified whether our Sponsor has sufficient funds to satisfy its indemnity obligations and we believe that our Sponsor’s only assets are securities of XPDB. Therefore, we cannot assure you that our 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 $10.10 per Public Share. In such event, we 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 our officers or directors will indemnify us 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) $10.10 per Public Share or (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes, and our Sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against our Sponsor to enforce its indemnification obligations. While we currently expect that our independent directors would take legal action on our behalf against our Sponsor to enforce its indemnification obligations to us, it is possible that our independent directors in exercising their business judgment may choose not to do so 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. We have not asked our Sponsor to reserve for such indemnification obligations and there is no assurance that our Sponsor would be able to satisfy those obligations. Accordingly, there is no assurance that due to claims of creditors the actual value of the per share redemption price will not be less than $10.10 per Public Share.

We seek to reduce the possibility that our Sponsor has to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than our independent auditor), prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Our Sponsor will also not be liable as to any claims under our indemnity of the underwriters of the XPDB IPO against certain liabilities, including liabilities under the Securities Act. We have access to approximately $494,804 of proceeds from the XPDB IPO (as of June 30, 2023) with which to pay any such potential claims (including costs and expenses incurred in connection with our liquidation, currently estimated to be no more than approximately $100,000).

In the event that we liquidate and it is subsequently determined that the reserve for claims and liabilities is insufficient, stockholders who received funds from our Trust Account could be liable for claims made by creditors.

Under the DGCL, stockholders may be held liable for claims by third parties against a corporation to the extent of distributions received by them in a dissolution. The pro rata portion of our Trust Account distributed to our XPDB Public Stockholders upon the redemption of our Public Shares in the event we do not complete an initial business combination by December 14, 2023 or such further extended date as determined by the XPDB Board in accordance with the Existing Charter may be considered a liquidating distribution under Delaware law. Delaware law provides that if a corporation complies with certain procedures set forth in Section 280 of the DGCL intended to ensure that it makes reasonable provision for all claims against it, including a 60-day notice period during which any third-party claims can be brought against the corporation, a 90-day period during which the corporation may reject any claims brought, and an additional 150-day waiting period before any liquidating distributions are made to stockholders, any

104

Table of Contents

liability of stockholders with respect to a liquidating distribution is limited to the lesser of such stockholder’s pro rata share of the claim or the amount distributed to the stockholder, and any liability of the stockholder would be barred after the third anniversary of the dissolution.

Furthermore, if the pro rata portion of our Trust Account distributed to our XPDB Public Stockholders upon the redemption of our Public Shares in the event we do not complete an initial business combination by the end of the Completion Window is not considered a liquidating distribution under Delaware law and such redemption distribution is deemed to be unlawful, then pursuant to Section 174 of the DGCL, the statute of limitations for claims of creditors could then be six years after the unlawful redemption distribution, instead of three years, as in the case of a liquidating distribution. If we are unable to complete an initial business combination by the end of the Completion Window, we will be required to: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the Public Shares, at a per share price, payable in cash, equal to (i) 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 us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by (ii) the number of then outstanding Public Shares, which redemption will completely extinguish XPDB Public Stockholders’ rights as stockholders of XPDB (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and the XPDB Board, dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Accordingly, it is our intention to redeem our Public Shares as soon as reasonably possible following the end of the Completion Window and, therefore, we do not intend to comply with those procedures. As such, our stockholders could potentially be liable for any claims to the extent of distributions received by them (but no more) and any liability of our stockholders may extend well beyond the third anniversary of such date.

Because we will not be complying with Section 280, Section 281(b) of the DGCL requires us to adopt a plan, based on facts known to us at such time that will provide for our payment of all existing and pending claims or claims that may be potentially brought against us within the subsequent 10 years.

However, because we are a blank check company, rather than an operating company, and our operations are limited to searching for prospective target businesses to acquire, the only likely claims to arise would be from our vendors (such as lawyers, investment bankers, etc.) or prospective target businesses. As described above, pursuant to the obligation contained in the IPO Underwriting Agreement, we have sought and will continue to seek to have all vendors, service providers, prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account. As a result of this obligation, the claims that could be made against us are significantly limited and the likelihood that any claim that would result in any liability extending to the Trust Account is remote.

Further, our Sponsor may be liable only to the extent necessary to ensure that the amounts in the Trust Account are not reduced below (i) $10.10 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, in each case net of the amount of interest withdrawn to pay taxes and will not be liable as to any claims under our indemnity of the underwriters of the XPDB IPO against certain liabilities, including liabilities under the Securities Act. In the event that an executed waiver is deemed to be unenforceable against a third party, our Sponsor will not be responsible to the extent of any liability for such third-party claims.

If we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our stockholders. To the extent any bankruptcy claims deplete the Trust Account, there is no assurance that we will be able to return $10.10 per share to our XPDB Public Stockholders. Additionally, if we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by our stockholders. Furthermore, the XPDB Board may be viewed as having breached its fiduciary duty to our creditors and/or may have acted in bad faith,

105

Table of Contents

thereby exposing itself and our company to claims of punitive damages, by paying XPDB Public Stockholders from the Trust Account prior to addressing the claims of creditors. There is no assurance that claims will not be brought against us for these reasons.

Our XPDB Public Stockholders will be entitled to receive funds from the Trust Account only (i) in the event of the redemption of our Public Shares if we do not complete an initial business combination by the end of the Completion Window, subject to applicable law, (ii) in connection with a stockholder vote to approve an amendment to our Existing Charter to modify the substance or timing of our obligation to redeem 100% of our Public Shares if we have not consummated an initial business combination by the end of the Completion Window or with respect to any other material provisions relating to stockholders’ rights or pre-initial business combination activity or (iii) our completion of an initial business combination, and then only in connection with those shares of our common stock that such stockholder properly elected to redeem, subject to the limitations described herein. In no other circumstances will a stockholder have any right or interest of any kind to or in the Trust Account. In the event we seek stockholder approval in connection with the Business Combination, a stockholder’s voting in connection with the Business Combination alone will not result in a stockholder’s redeeming its shares to us for an applicable pro rata portion of the Trust Account. Such stockholder must have also exercised its redemption rights as described above. These provisions of our Existing Charter, like all provisions of our Existing Charter, may be amended with a stockholder vote.

Voting Restrictions in Connection with the Special Meeting

Pursuant to the terms of the Sponsor Support Agreement, the Sponsor and XPDB’s directors have agreed to vote any Founder Shares held by them and any Public Shares purchased during or after the XPDB IPO in favor of each of the Proposals presented at the Special Meeting. See the section entitled “Other Agreements — Sponsor Support Agreement” for more information. The Initial Stockholders own approximately 40% of XPDB’s outstanding common stock entitled to vote thereon. The quorum and voting thresholds at the Special Meeting and the Sponsor Support Agreement may make it more likely that XPDB will consummate the Business Combination.

Facilities

We currently maintain our executive offices at 321 North Clark Street, Suite 2440, Chicago, Illinois 60654 and our telephone number is (312) 262-5642. Our executive offices are provided to us by affiliates of the Sponsor. Commencing on December 9, 2021, we have agreed to reimburse affiliates of our Sponsor for office space, secretarial and administrative services provided to members of our management team in the amount of $20,000 per month, which will be paid at the consummation of the Business Combination.

Upon completion of the Business Combination or our liquidation, we will cease paying these monthly fees. No compensation of any kind, including finder’s and consulting fees, will be paid by XPDB to our Sponsor, executive officers and directors, or any of their respective affiliates, for services rendered prior to or in connection with the completion of a Business Combination except for reimbursement for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations and advisory fees and consulting fees in an aggregate amount of up to $3,000,000 that will be paid to XMS Capital and TEP in connection with the Business Combination. Our audit committee will review on a quarterly basis all payments that were made to our Sponsor, officers, directors or our or their affiliates.

Employees

We currently have five officers: Patrick C. Eilers, Chief Executive Officer, James P. Nygaard, Jr., Chief Financial Officer, John B. Sexton, Vice President, Patrick O’Hara, Vice President, and John P. McGarrity, General Counsel and Secretary. These individuals are not obligated to devote any specific number of hours to our matters but they intend to devote as much of their time as they deem necessary to our affairs until we have completed the Business Combination. The amount of time they will devote in any time period will vary based on whether a target business has been selected for the Business Combination and the stage of the business combination process we are in. We do not intend to have any full-time employees prior to the completion of the Business Combination.

Legal Proceedings

There is no material litigation, arbitration or governmental proceeding currently pending against us or any members of our management team in their capacity as such.

Number and Terms of Office of Officers and Directors

The XPDB 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 our first annual meeting of stockholders) serving a three-year term. In accordance with the Nasdaq corporate governance requirements, we were not required to hold an annual meeting until one year after our first fiscal year end following our listing on the Nasdaq. The term of office of the first class of directors, consisting of Mr. Gaynor, will expire at our first annual meeting of stockholders. The term of office of the second class of directors, consisting of Mr. Dabbar and Mr. Widham, will expire at our second

109

Table of Contents

annual meeting of the stockholders. The term of office of the third class of directors, consisting of Mr. Brombach and Mr. Eilers, will expire at our third annual meeting of stockholders. We may not hold an annual meeting of stockholders until after we complete our initial business combination.

Prior to the completion of an initial business combination, any vacancy on the XPDB Board may be filled by a nominee chosen by holders of a majority of our Founder Shares. In addition, prior to the completion of an initial business combination, holders of a majority of our Founder Shares may remove a member of the XPDB Board for any reason.

Our officers are appointed by the XPDB Board and serve at the discretion of the XPDB Board, rather than for specific terms of office. The XPDB Board is authorized to nominate persons to the offices set forth in our Existing Charter as it deems appropriate. Our Existing Charter provides that our officers may consist of one or more chairman of the XPDB Board, chief executive officer, president, chief financial officer, vice president, secretary, treasurer and such other offices as may be determined by the XPDB Board. Pursuant to the Merger Agreement, XPDB shall cause persons mutually agreed to by XPDB and Montana (such agreement not to be unreasonably withheld, conditioned or delayed) to become the directors and officers of the Post-Combination Company at the effective time of the Merger.

Director Independence

The Nasdaq listing standards require that a majority of our board of directors be independent. An “independent director” is defined generally as a person that, in the opinion of the listed company’s board of directors, has no material relationship with the listed company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the company). The XPDB Board has determined that Mr. Dabbar, Mr. Gaynor and Mr. Widham are “independent directors” as defined in the Nasdaq listing standards and applicable SEC rules. Our independent directors have regularly scheduled meetings at which only independent directors are present.

Executive Compensation

None of our executive officers or directors have received any cash compensation for services rendered to us. Commencing on December 9, 2021, we have agreed to reimburse affiliates of our Sponsor for office space and administrative support services provided to us in the amount of $20,000 per month, which will be paid at the consummation of the Business Combination. Furthermore, in connection with the Business Combination, we may potentially make a cash payment in an aggregate amount of up to $3,000,000 to XMS Capital, TEP or their respective affiliates for any financial advisory, placement agency or other similar investment banking or consulting services that XMS Capital, TEP or their respective affiliates may provide to us in connection with the Business Combination, and may reimburse to XMS Capital, TEP or their respective affiliates for any out-of-pocket expenses incurred by it in connection with the performance of such services. In addition, our Sponsor, executive officers and directors, or any of their respective affiliates will be reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee will review on a quarterly basis all payments that were made to our Sponsor, executive officers or directors, or our or their affiliates. Any such payments prior to an initial business combination will be made using funds held outside the Trust Account. Other than quarterly audit committee review of such reimbursements, we do not expect to have any additional controls in place governing our reimbursement payments to our directors and executive officers for their out-of-pocket expenses incurred in connection with our activities on our behalf in connection with identifying and completing an initial business combination. Other than these payments and reimbursements, no compensation of any kind, including finder’s and consulting fees, will be paid by the Company to our Sponsor, executive officers and directors, or any of their respective affiliates, prior to completion of our initial business combination.

After the completion of our initial business combination, directors or members of our management team who remain with us may be paid consulting or management fees from the Post-Combination Company. All of these fees will be fully disclosed to stockholders, to the extent then known, in the proxy solicitation materials or tender offer materials furnished to our stockholders in connection with the proposed business combination. We have not established any limit on the amount of such fees that may be paid by the Post-Combination Company to our directors or members of management. It is unlikely the amount of such compensation will be known at the time of the proposed business combination, because the directors of the post combination business will be responsible for determining executive

110

Table of Contents

officer and director compensation. Any compensation to be paid to our executive officers will be determined, or recommended to the XPDB Board for determination, either by a compensation committee constituted solely by independent directors or by a majority of the independent directors on the XPDB Board.

We do not intend to take any action to ensure that members of our management team maintain their positions with us after the completion of our initial business combination, although it is possible that some or all of our executive officers and directors may negotiate employment or consulting arrangements to remain with us after our initial business combination. The existence or terms of any such employment or consulting arrangements to retain their positions with us may influence our management’s motivation in identifying or selecting a target business but we do not believe that the ability of our management to remain with us after the completion of our initial business combination will be a determining factor in our decision to proceed with any potential business combination. We are not party to any agreements with our executive officers and directors that provide for benefits upon termination of employment.

Committees of the Board of Directors

The XPDB Board has three standing committees: an audit committee, a compensation committee and a corporate governance and nominating committee. Subject to phase-in rules and a limited exception, the rules of the Nasdaq and Rule 10A of the Exchange Act require that the audit committee of a listed company be comprised solely of independent directors.

Audit Committee

We have established an audit committee of the XPDB Board. Mr. Gaynor, Mr. Widham and Mr. Dabbar serve as members of our audit committee. The XPDB Board has determined that each of Mr. Gaynor, Mr. Widham and Mr. Dabbar are independent under the Nasdaq listing standards and applicable SEC rules. Mr. Gaynor serves as the chairman of the audit committee. Each member of the audit committee is financially literate and the XPDB Board has determined that Mr. Gaynor qualifies as an “audit committee financial expert” as defined in applicable SEC rules. We have adopted an audit committee charter, which details the primary functions of the audit committee, including:

• appointing, compensating and overseeing our independent registered public accounting firm;

• reviewing and approving the annual audit plan for the company;

• overseeing the integrity of our financial statements and our compliance with legal and regulatory requirements;

• discussing the annual audited financial statements and unaudited quarterly financial statements with management and the independent registered public accounting firm;

• pre-approving all audit services and permitted non-audit services to be performed by our independent registered public accounting firm, including the fees and terms of the services to be performed;

• appointing or replacing the independent registered public accounting firm;

• monitoring our environmental sustainability and governance practices;

• establishing procedures for the receipt, retention and treatment of complaints received by us regarding accounting, internal accounting controls or reports which raise material issues regarding our financial statements or accounting policies;

• discussing earnings press releases and financial information provided to analysts and rating agencies;

• discussing with management our policies and practices with respect to risk assessment and risk management;

• reviewing any material transaction between our Chief Financial Officer that has been approved in accordance with our Code of Ethics for our officers, and providing prior written approval of any material transaction between us and our Chief Executive Officer; and

• producing an annual report for inclusion in our proxy statement, in accordance with applicable rules and regulations.

Table of Contents

The audit committee is a separately designated standing committee established in accordance with Section 3(a)(58)(A) of the Exchange Act.

Compensation Committee

We have established a compensation committee of the XPDB Board. The members of our compensation committee are Mr. Gaynor, Mr. Widham, and Mr. Dabbar, and Mr. Widham serves as chairman of the compensation committee. Under the Nasdaq listing standards and applicable SEC rules, we are required to have a compensation committee composed entirely of independent directors. The XPDB Board has determined that each of Mr. Gaynor, Mr. Widham, and Mr. Dabbar are independent.

We have adopted a compensation committee charter, which details the primary functions of the compensation committee, including:

• reviewing and approving corporate goals and objectives relevant to our Chief Executive Officer’s compensation (if any), evaluating our Chief Executive Officer’s performance in light of those goals and objectives, and setting our Chief Executive Officer’s compensation level (if any) based on this evaluation;

• setting salaries and approving incentive compensation and equity awards, as well as compensation policies, for all other officers who file reports of their ownership, and changes in ownership, of XPDB Common Stock under Section 16(a) of the Exchange Act (the “Section 16 Officers”), as designated by the XPDB Board;

• making recommendations to the XPDB Board with respect to incentive compensation programs and equity-based plans that are subject to board approval;

• approving any employment or severance agreements with our Section 16 Officers;

• granting any awards under equity compensation plans and annual bonus plans to our Chief Executive Officer and the Section 16 Officers;

• approving the compensation of our directors; and

• producing an annual report on executive compensation for inclusion in our proxy statement, in accordance with applicable rules and regulations.

The compensation committee charter also provides that the compensation committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, 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.

Corporate Governance and Nominating Committee

We have established a corporate governance and nominating committee of the XPDB Board. The members of our corporate governance and nominating committee are Mr. Gaynor, Mr. Widham, and Mr. Dabbar, and Mr. Dabbar serves as chairman of the corporate governance and nominating committee. Under the Nasdaq listing standards, we are required to have a corporate governance and nominating committee composed entirely of independent directors. The XPDB Board has determined that each of Mr. Gaynor, Mr. Widham, and Mr. Dabbar are independent.

We have adopted a corporate governance and nominating committee charter, which details the primary functions of the corporate governance and nominating committee, including:

• identifying individuals qualified to become members of the XPDB Board and making recommendations to the XPDB Board regarding nominees for election;

• reviewing the independence of each director and making a recommendation to the XPDB Board with respect to each director’s independence;

112

Table of Contents

• developing and recommending to the XPDB Board the corporate governance principles applicable to us and reviewing our corporate governance guidelines at least annually;

• making recommendations to the XPDB Board with respect to the membership of the audit, compensation and corporate governance and nominating committees;

• overseeing the evaluation of the performance of the XPDB Board and its committees on a continuing basis, including an annual self-evaluation of the performance of the corporate governance and nominating committee;

• considering the adequacy of our governance structures and policies, including as they relate to our sustainability and governance practices;

• considering director nominees recommended by stockholders; and

• reviewing our overall corporate governance and reporting to the XPDB Board on its findings and any recommendations.

Guidelines for Selecting Director Nominees

The guidelines for selecting nominees, which are specified in the corporate governance and nominating committee charter, generally provide that persons to be nominated:

• should possess personal qualities and characteristics, accomplishments and reputation in the business community;

• should have current knowledge and contacts in the communities in which we do business and in our industry or other industries relevant to our business;

• should have the ability and willingness to commit adequate time to the board of directors and committee matters;

• should demonstrate ability and willingness to commit adequate time to the board of directors and committee matters;

• should possess the fit of the individual’s skills and personality with those of other directors and potential directors in building a board of directors that is effective, collegial and responsive to our needs; and

• should demonstrate diversity of viewpoints, background, experience, and other demographics, and all aspects of diversity in order to enable the board to perform its duties and responsibilities effectively, including candidates with a diversity of age, gender, nationality, race, ethnicity, and sexual orientation.

Each year in connection with the nomination of candidates for election to the XPDB Board, the corporate governance and nominating committee will evaluate the background of each candidate, including candidates that may be submitted by our stockholders.

Compensation Committee Interlocks and Insider Participation

None of our executive officers currently serves, and in the past year has not served, as a member of the board of directors or compensation committee (or other committee performing equivalent functions) of any entity that has one or more executive officers serving on the XPDB Board or its compensation committee.

Code of Ethics

We have adopted a Code of Ethics applicable to our directors, officers and employees. A copy of the Code of Ethics will be provided without charge upon written request to our principal executive offices. We intend to disclose any amendments to or waivers of certain provisions of our Code of Ethics in a Current Report on Form 8-K.

Securities Authorized for Issuance Under Equity Compensation Plans

As of June 30, 2023, we had no equity compensation plans or outstanding equity awards.

Limitation on Liability and Indemnification of Officers and Directors

Our Existing Charter provides that our officers and directors will be indemnified by us to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended. In addition, our Existing Charter provides that our directors will not be personally liable for monetary damages to us or our stockholders for breaches of their fiduciary duty as directors, unless they violated their duty of loyalty to us or our stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived an improper personal benefit from their actions as directors.

We entered into agreements with our officers and directors to provide contractual indemnification in addition to the indemnification provided for in our Existing Charter. Our bylaws also will permit us to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions, regardless of whether Delaware law would permit such indemnification.

We purchased a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors. Except with respect to any Public Shares they may have acquired in the XPDB IPO or thereafter (in the event we do not consummate an initial business combination), our officers and directors have agreed to waive (and any other persons who may become an officer or director prior to the initial business combination will also be required to waive) any right, title, interest or claim of any kind in or to any monies in the Trust Account, and not to seek recourse against the Trust Account for any reason whatsoever, including with respect to such indemnification.

These provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against officers and directors, even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against officers and directors pursuant to these indemnification provisions.

We believe that these provisions, the directors’ and officers’ liability insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

XPDB MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

The following discussion and analysis of XPDB’s financial condition and results of operations should be read in conjunction with XPDB’s financial statements and the notes thereto contained elsewhere in this proxy statement/prospectus. Certain information contained in the discussion, including, but not limited to, those described under the heading “Risk Factors” and analysis set forth below includes forward-looking statements that involve risks and uncertainties. References in this section to “XPDB,” “we,” “us,” “our” and the “Company” are intended to mean the business and operations of XPDB.

Overview

We are a blank check company incorporated in Delaware on March 23, 2021, formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses. We are an emerging growth company and, as such, we are subject to all of the risks associated with emerging growth companies.

Our Sponsor is XPDI Sponsor II LLC, a Delaware limited liability company. The registration statement for the XPDB IPO was declared effective on December 9, 2021. On December 14, 2021, we consummated the XPDB IPO of 28,750,000 units, which included the exercise of the underwriters’ option to purchase an additional 3,750,000 units at the initial public offering price to cover over-allotments (the “Over-Allotment Units”), at $10.00 per unit, generating gross proceeds of $287.5 million, and incurring offering costs of approximately $20.7 million, of which approximately $10.1 million was a Deferred Discount, which was subsequently reduced to approximately $6 million following the resignation of BofA as an underwriter as described below.

Simultaneously with the closing of the XPDB IPO, we completed the Private Placement of 11,125,000 Private Placement Warrants, at a price of $1.00 per Private Placement Warrant to our Sponsor and the Anchor Investors, generating proceeds of approximately $11.1 million.

Upon the closing of the XPDB IPO and the Private Placement on December 14, 2021, approximately $290.4 million ($10.10 per unit) of the net proceeds of the sale of the units in the XPDB IPO, including proceeds from the sale of the Over-Allotment Units and certain of the proceeds from the sale of the Private Placement Warrants, were deposited into the Trust Account and approximately $1.7 million of such net proceeds were deposited in our operating account to pay expenses in connection with the closing of the XPDB IPO and for working capital following the XPDB IPO. The proceeds held in the Trust Account have been invested in U.S. “government securities,” within the meaning of Section 2(a)(16) of the Investment Company Act, as amended, 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 an initial business combination and (ii) the distribution of the Trust Account as described below.

Our management has broad discretion with respect to the specific application of the net proceeds of the XPDB IPO and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating an initial business combination. There is no assurance that we will be able to complete a business combination successfully. We must complete one or more initial business combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (net of amounts disbursed to management for working capital purposes and excluding the Deferred Discount and taxes payable on the interest earned on the Trust Account) at the time of the agreement to enter into the initial business combination. However, we will only complete an initial business combination if the post-transaction company owns or acquires 50% or more of the 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.

On May 15, 2023, the Company filed a definitive proxy statement for the solicitation of proxies in connection with the Extension Special Meeting to consider and vote on, among other proposals, the extension of the date by which the Company must consummate an initial business combination from June 14, 2023 to December 14, 2023, and to allow the Company, without another stockholder vote, by resolution of the XPDB Board to elect to further extend such date in one-month increments up to three additional times until March 14, 2024, unless the closing of a an initial business combination shall have occurred prior thereto, or such earlier date as determined by the XPDB Board to be in the best interests of the Company (such proposal, the “Extension Amendment Proposal”), and the amendment of the Company’s

115

Table of Contents

amended and restated certificate of incorporation to remove the limitation that XPDB may not redeem Public Shares to the extent that such redemption would result in XPDB having net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act (or any successor rule)) of less than $5,000,001 (such proposal, the “Redemption Limitation Amendment Proposal”).

At the Extension Special Meeting on June 9, 2023, the Company’s stockholders approved the Extension Amendment Proposal and the Redemption Limitation Amendment Proposal. In connection with the stockholders’ vote at the Extension Special Meeting, the stockholders elected to redeem 18,141,822 shares of XPDB Class A Common Stock at a redemption price of approximately $10.37 per share, for an aggregate redemption amount of approximately $188,132,132 (the “June Redemptions”). After the satisfaction of the June Redemptions, the balance in the Trust Account as of June 30, 2023 was approximately $110,058,882. Upon completion of the June Redemptions, 10,608,178 shares of XPDB Class A Common Stock and 7,187,500 shares of XPDB Class B Common Stock remain issued and outstanding.

In connection with the approval of the Extension Amendment Proposal, the Company or the Sponsor will deposit, beginning on June 15, 2023, and thereafter on the 10th day of each month (or if such 10th day is not a business day, on the business day immediately preceding such 10th day), additional funds into the Trust Account in an amount equal to the lesser of (i) $0.03 multiplied by the number of shares of XPDB Class A Common Stock then outstanding and not redeemed in connection with the Extension Special Meeting and (ii) $300,000. As a result, $300,000 was deposited in the Trust Account by the Company on June 15, 2023, July 10, 2023 and August 10, 2023. On September 8, 2023, $300,000 was deposited in the Trust Account by the Sponsor.

Liquidity, Capital Resources and Going Concern

Our liquidity needs to date have been satisfied through a capital contribution of $25,000 from the Sponsor to purchase XPDB Class B Common Stock, the related party loan under a promissory note of approximately $115,000 from the Sponsor, which was repaid in full on December 17, 2021, and the net proceeds from the consummation of the Private Placement not held in the Trust Account. In addition, in order to finance transaction costs in connection with an initial business combination, our officers, directors and Initial Stockholders may, but are not obligated to, provide working capital loans. As of June 30, 2023, there were no amounts outstanding under any working capital loans.

In connection with the Company’s assessment of going concern considerations in accordance with the Financial Accounting Standards Board’s (“FASB’s”) Accounting Standards Codification (“ASC”) Topic 205-40, “Presentation of Financial Statements — Going Concern,” management has determined that the liquidity needs, mandatory liquidation and subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern, which is considered to be one year from the issuance of these financial statements. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after December 14, 2023. The financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern. The Company intends to complete a business combination before the mandatory liquidation date, as it may be extended. Over this time period, the Company will be using the funds outside of the Trust Account for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. These conditions raise substantial doubt about the Company’s ability to continue as a going concern through one year from the issuance date of these financial statements. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

We continue to evaluate the impact of the COVID-19 pandemic on the Company and have concluded that while it is reasonably possible that the virus could have a negative effect on our financial position, results of the Company’s operations and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

In February 2022, the Russian Federation and Belarus commenced a military action with the country of Ukraine. As a result of this action, various nations, including the United States, have instituted economic sanctions against the Russian Federation and Belarus. Further, the impact of this action and related sanctions on the world economy are not determinable as of the date of these financial statements.

Results of Operations

Our entire activity since inception up to June 30, 2023 has been related to our formation, preparation for the XPDB IPO, and since the closing of the XPDB IPO, the search for a prospective initial business combination. We will not generate any operating revenues until after the completion of our initial business combination. We generate non-operating income in the form of investment income from the Trust Account. We will continue to incur increased 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 three months ended June 30, 2023, we had a net loss of approximately $0.2 million, which consisted of approximately $2.8 million in operating expenses and approximately $0.7 million in income tax expenses, offset by approximately $3.1 million of income from investments held in the Trust Account and reversal of transaction costs incurred in connection with the XPDB IPO of approximately $0.2 million. Operating expenses were comprised of approximately $2.7 million of general and administrative expenses, $60,000 of general and administrative expenses — related party, and $50,000 of franchise tax expenses.

For the three months ended June 30, 2022, we had net income of approximately $40,000, which consisted of approximately $385,000 of income from investments held in the Trust Account, partially offset by approximately $314,000 in operating expenses and approximately $31,000 in income tax expenses. Operating expenses were comprised of approximately $188,000 of general and administrative expenses, $60,000 of general and administrative expenses — related party, and $65,000 of franchise tax expenses.

For the six months ended June 30, 2022, we had a net loss of approximately $385,000, which consisted of approximately $767,000 in operating expenses and approximately $31,000 in income tax expenses, partially offset by approximately $412,000 of income from investments held in the Trust Account. Operating expenses were comprised of approximately $532,000 of general and administrative expenses, $120,000 of general and administrative expenses — related party, and $115,000 of franchise tax expenses.

For the year ended December 31, 2022, we had net income of approximately $2.0 million, which consisted of approximately $4.2 million of income from investments held in the Trust Account, partially offset by approximately $1.3 million in operating expenses and approximately $802,000 in income tax expenses. Operating expenses were comprised of approximately $888,000 of general and administrative expenses, $240,000 of general and administrative expenses — related party, and $215,000 of franchise tax expense.

For the period from March 23, 2021 (inception) through December 31, 2021, we had a net loss of approximately $544,000, which consisted of approximately $392,000 in general and administrative expenses and approximately $152,000 in franchise tax expense, partially offset by approximately $900 in income from investments held in the Trust Account.

Contractual Obligations

Registration Rights

The holders of XPDB Class B Common Stock, Private Placement Warrants and warrants that may be issued upon conversion of working capital loans, if any (and any shares of common stock issuable upon the exercise of the Private Placement Warrants or warrants issued upon conversion of the working capital loans and upon conversion of the Founder Shares), were entitled to registration rights pursuant to the Registration Rights Agreement to be signed prior to the consummation of the XPDB IPO. These holders are entitled to certain demand and “piggyback” registration rights. However, the Registration Rights Agreement provides that we 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. We will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

BofA and Barclays, the underwriters in the XPDB IPO, were entitled to a Deferred Discount (as defined in the IPO Underwriting Agreement) of $0.35 per share, or $10,062,500 in the aggregate. On June 20, 2023, BofA formally notified XPDB in writing that it had resigned and withdrew from its role in the Business Combination and thereby waived its entitlement to its portion of the Deferred Discount.

BofA did not communicate to XPDB its reasons for its resignation or waiver of the Deferred Discount, and XPDB did not correspond with BofA about the reasons for its resignation or waiver of the fee. BofA confirmed that its resignation was not a result of any dispute or disagreement with XPDB or any matter relating to XPDB’s operations, policies, procedures or practices. It is XPDB’s understanding that other companies have received similar resignation letters from investment banks in connection with other business combination transactions involving special purpose acquisition companies. However, investors should be aware that a fee waiver for services already rendered is unusual.

XPDB does not currently have any ongoing relationship with BofA. BofA did not have a role in the identification or evaluation of business combination targets, and BofA was not involved in the preparation of any disclosure included in this proxy statement/prospectus nor any analysis underlying disclosure included in this proxy statement/prospectus. Further, BofA has not assisted in the preparation or review of any materials for XPDB in connection with the Business Combination and did not participate in any other aspect of the Business Combination. As such, the resignation by BofA did not impact XPDB’s evaluation of the Business Combination.

Barclays did not resign as underwriter and remains entitled to a Deferred Discount of $0.35 per share, or approximately $6 million. Barclays has agreed that its $6 million capital markets advisory fee, payable to Barclays solely in the event that we complete a business combination, will be creditable against its portion of the Deferred Discount.

Administrative Support Services

Commencing on December 9, 2021, we have agreed to pay affiliates of our Sponsor a total of $20,000 per month for office space and administrative support services. Upon completion of our initial business combination or our liquidation, we will cease paying these monthly fees. In connection with our initial business combination, we may potentially make a cash payment in an aggregate amount of up to $3,000,000 to affiliates of our Sponsor or Anchor Investors for any financial advisory, placement agency or other similar investment banking or consulting services that affiliates of our Sponsor or Anchor Investors may provide to us in connection with our initial business combination, and may reimburse to affiliates of our Sponsor or Anchor Investors for any out-of-pocket expenses incurred by it in connection with the performance of such services.

Merger Agreement

On June 5, 2023, the Company and Merger Sub entered into the Merger Agreement with Montana, pursuant to which Merger Sub will merge with and into Montana, with Montana surviving the Merger as a wholly owned subsidiary of the Company. Following the Closing, the Company will be renamed “Montana Technologies Corporation.”

As part of the Business Combination, Montana Equityholders will receive aggregate consideration of approximately $421.9 million (subject to adjustment as described in the Merger Agreement), payable (i) in the case of holders of Montana Class B Common Units and Montana Class C Common Units, in the form of newly issued shares of Class A Common Stock, with a $10.00 value ascribed to each such share and which will entitle the holder thereof to one vote per share on all matters submitted to a vote of the holders of Class A Common Stock, whether voting separately as a class or otherwise, (ii) in the case of holders of Montana Class A Common Units, in the form of newly issued shares of Class B Common Stock, with a $10.00 value ascribed to each such share and which will entitle the holder thereof to a number of votes per share such that the Montana Equityholders as of immediately prior to the Closing will, immediately following the Closing, collectively own shares representing at least 80% of the voting power of all classes of capital stock of the Post-Combination Company entitled to vote on matters submitted to a vote of the stockholders of the Post-Combination Company, and (iii) in the case of holders of Montana Options and Montana Warrants, in the form of options and warrants of the Post-Combination Company, respectively, having substantially similar terms to the corresponding Montana Options and Montana Warrants. The Eligible Equityholders will also have the opportunity to receive additional equity consideration (in each case, in accordance with their respective pro rata share) in the form of Earnout Shares upon full completion of construction and operational viability (including all permitting, regulatory approvals and necessary or useful inspections) of new production capacity of Montana’s key components

or assemblies based solely on demand from bona fide customer commitments evidenced by binding contracts (or in the Post-Combination Company Board’s discretion, a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known price or pricing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA of more than $150,000,000, which shall be determined by a majority of the independent members of the Post-Combination Company Board in their sole discretion, equal to (i) the ratio of (x) (1) the Expected Annualized EBITDA less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000.

The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing. A majority of the independent members of the Post-Combination Company Board then serving will have sole discretion in determining, among other things, the achievement of the applicable milestones, the calculations of payments of Earnout Shares to the applicable Montana Equityholders, the dates on which construction and operational viability of new production capacity is deemed completed and whether to consent to a transfer of the applicable Montana Equityholder’s right to receive Earnout Shares. Earnout Shares issuable in respect of Montana Options outstanding as of immediately prior to the effective time of the Merger may be issued to the holder of such Montana Option only if such holder continues to provide services (whether as an employee, director or individual independent contractor) to the Post-Combination Company or one of its subsidiaries through the date on which such Earnout Shares are issued, as determined by a majority of the independent members of the Post-Combination Company Board.

Sponsor Support Agreement

In connection with the execution of the Merger Agreement and pursuant to the terms of the Sponsor Support Agreement entered into among the Sponsor, XPDB, Montana and other holders of XPDB Class B Common Stock, the Sponsor and the other holders of XPDB Class B Common Stock agreed to, among other things, (i) vote at the Special Meeting any Sponsor Securities held of record or thereafter acquired in favor of the Proposals presented by XPDB at such meeting, (ii) be bound by certain other covenants and agreements related to the Business Combination, (iii) be bound by certain transfer restrictions with respect to the Sponsor Securities and (iv) waive certain antidilution protections with respect to the Sponsor Securities, in each case, on the terms and subject to the conditions set forth in the Sponsor Support Agreement. In addition, pursuant to the terms of the Sponsor Support Agreement, the Sponsor has agreed to waive its redemption rights with respect to any Sponsor Securities in connection with the completion of a Business Combination (which waiver was provided in connection with the XPDB IPO and without any separate consideration paid in connection with providing such waiver), has agreed not to transfer any Public Shares and Founder Shares held by it during the time prior to (i) Closing or (ii) the termination of the Merger Agreement, has agreed to waive anti-dilution protections and has agreed to subject certain of the shares of Class A Common Stock held by Sponsor following the conversion of the Founder Shares as of the Closing to certain vesting provisions. Specifically, the Sponsor Support Agreement provides that as of immediately prior to (but subject to) the Closing, 1,380,736 Subject Vesting Shares will be subject to an earnout, with the Subject Vesting Shares vesting during the Vesting Period (i) simultaneously with the Performance Vesting Trigger and (ii) up to 50% of the Subject Vesting Shares (including any vested Subject Vesting Shares from the Performance Vesting Trigger) vesting on any day following the Closing when the Closing Share Price equals or exceeds $12.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) and all remaining Subject Vesting Shares vesting when the Closing Share Price equals or exceeds $14.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like).

The Sponsor Support Agreement will terminate on the earlier of (i) the date the Business Combination becomes effective and (ii) the termination of the Merger Agreement in accordance with its terms.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with GAAP 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 the reported amounts of income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following as our critical accounting policies:

Derivative Warrant Liabilities

We do not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. Management evaluates all of our financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to FASB ASC Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”) and FASB ASC Topic 815-40, “Derivatives and Hedging — Contracts in Entity’s Own Stock” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be classified as liabilities or as equity, is re-assessed at the end of each reporting period. The XPDB public warrants and the Private Placement Warrants are not precluded from equity classification, based on the guidance in ASC 480 and ASC 815. Equity-classified contracts are initially measured at fair value (or allocated value). Subsequent changes in fair value are not recognized as long as the contracts continue to be classified in equity.

XPDB Class A Common Stock Subject to Possible Redemption

We account for our XPDB Class A Common Stock subject to possible redemption in accordance with the guidance in ASC 480. XPDB Class A Common Stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable XPDB Class A Common Stock (including XPDB Class A Common Stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) is classified as temporary equity. At all other times, XPDB Class A Common Stock is classified as stockholders’ equity. XPDB Class A Common Stock features certain redemption rights that are considered to be outside of our control and subject to the occurrence of uncertain future events. Accordingly, all of our outstanding shares of XPDB Class A Common Stock is presented at redemption value as temporary equity, outside of the stockholders’ equity section of our balance sheets.

Under ASC 480, we have elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of the reporting period. This method would view the end of the reporting period as if it were also the redemption date of the security. Effective with the closing of the XPDB IPO, we recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit.

Net (Loss) Income Per Common Share

We comply with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” We have two classes of shares, which are referred to as XPDB Class A Common Stock and XPDB Class B Common Stock. Income and losses are shares pro rata between the two classes of shares. Net (loss) income per common share is calculated by dividing the net (loss) income by the weighted average shares of common stock outstanding for the respective period.

The calculation of diluted net (loss) income does not consider the effect of the XPDB public warrants and the Private Placement Warrants to purchase an aggregate of 25,500,000 shares of XPDB Class A Common Stock in the calculation of diluted (loss) income per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net (loss) income per share is the same as basic net (loss) income per share for the three and six months ended June 30, 2023 and 2022, the year ended December 31, 2022 and the period from March 23, 2021 (inception) through December 31, 2021. Accretion associated with the redeemable XPDB Class A Common Stock is excluded from earnings per share as the redemption value approximates fair value.

Our management does not believe that there are any recently issued, but not yet effective, accounting pronouncements, that if currently adopted, would have a material effect on our condensed consolidated balance sheets.

Off Balance Sheet Arrangements and Contractual Obligations

As of June 30, 2023, we did not have any off-balance sheet arrangements as defined in the rules and regulations of the SEC and did not have any commitments or contractual obligations.

JOBS Act

The JOBS Act contains provisions that, among other things, relax certain reporting requirements for qualifying public companies. We qualify as an “emerging growth company” and under the JOBS Act are allowed to comply with new or revised accounting pronouncements based on the effective date for private (not publicly traded) companies. We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. As a result, the financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Additionally, we are in the process of evaluating the benefits of relying on the other reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of the XPDB IPO or until we are no longer an “emerging growth company,” whichever is earlier.

INFORMATION ABOUT MONTANA

Unless the context otherwise requires, all references in this section to “Montana,” the “Company,” “we,” “us,” “our” and other similar terms refer to the business of Montana Technologies LLC prior to the consummation of the Business Combination, which will be the business of the Post-Combination Company and its subsidiaries following the consummation of the Business Combination.

Company Overview

We are an atmospheric renewable energy and water harvesting technology company that aims to provide energy and cost-efficient sustainable dehumidification, evaporative cooling and atmospheric water generation. As compared to currently existing HVAC systems, our AirJoule technology is designed to reduce energy consumption, minimize/eliminate harmful refrigerants, and generate material cost efficiencies. AirJoule is a climate solution technology that harvests the untapped supply of renewable thermal energy in water vapor in the atmosphere in an effort to provide significant energy efficiency gains in HVAC, as well as a potential source of potable water. We are focused on scaling manufacturing through global joint ventures and deploying AirJoule units worldwide as a key part of the solution to address global warming and water scarcity.

Company Background

We were established as Montana Technologies LLC in 2018 and are headquartered in Ronan, Montana. In the first quarter of 2021, we obtained an exclusive worldwide license from Pacific Northwest National Laboratory (“PNNL”) with respect to its self-regenerating dehumidifier technology and executed a strategic project partnership agreement with PNNL to further develop enhancements to the technology. See “— Our Competitive Strengths — Our Partners — PNNL.” In the third quarter of 2021, we entered into a joint venture with an affiliate of CATL for purposes of manufacturing and commercializing our AirJoule units, which utilize the regenerating dehumidifier technology conceived at PNNL, in certain countries. We also have an established global supplier relationship with BASF, the an international chemical company, to manufacture to our specifications under trade secret, proprietary materials that are critical for the AirJoule technology. In the first quarter of 2023, we completed the fourth prototype of our AirJoule unit, which can deliver up to 200 liters per day of water, with an energy consumption as low as 130 watt hours per liter (“WH/L”). We anticipate that we will complete a production-ready prototype of our AirJoule unit by the end of the fourth quarter of 2023 that will deliver up to 360 liters of water per day at between 60-90 WH/L, depending on humidity. Our AirJoule unit also enables evaporative cooling using its own water harvested from air in regions where current conventional HVAC systems are typically less effective and is designed to reduce electrical consumption by as much as 75% and reducing/eliminating the need for refrigerants, as compared to currently existing HVAC systems. We expect to commence our first production line, manufacturing end-market-ready AirJoule units in 2024.

Industry Background

HVAC

According to The Brainy Insights, the global HVAC system market was valued at approximately $214 billion in 2022 and is expected to reach a value of approximately $358 billion by 2032 at a compound annual growth rate of 5.27% from 2023 to 2032(1). The Rocky Mountain Institute estimates that cooling demand in developing economies will increase 5x by 2050, with global stock of air conditioners in buildings growing by approximately 4 billion units by 2050, which amounts to 10 new air conditioners sold every second for the next 30 years. Further, according to the U.S. Energy Information Administration (the “EIA”), the single largest demand for power in the United States is HVAC for buildings, accounting for approximately 33% of total energy use. In 2020, cooling the interior of residential and commercial buildings accounted for about 10% of the United States’ total energy usage. Our products and technologies aim to make HVAC systems more efficient by reducing energy use and lowering costs by up to 75%.

There are various types of HVAC systems, but the basic mechanisms are similar across all types. A mechanical system is used to draw in air, which is then processed and adjusted to the desired temperature. When the temperature is lowered with current conventional cooling equipment, water vapor in the air condenses into water. During this process, condensation heat is generated, thus the cooling mechanism must be powerful enough so that the cooling effect produced exceeds the rise in temperature resulting from condensation heat, in order to lower the net temperature of the environment in which this system is being used. Therefore, a significant amount of energy is required to offset condensation heat and lower the indoor temperature, particularly in increasingly hot and humid environments.

HVAC systems are used in various industrial facilities for their ventilation, filtration and cooling functions. Major end-user industries include wastewater, drinking water distribution, gas solution and petroleum solution facilities, to name a few. The high cost of installation and maintenance of HVAC systems makes it costly and difficult for mid-and small-scale companies to put HVAC systems in place. Our platform, however, attempts to solve legacy thermal constraints encountered by current conventional designs by utilizing metal-organic frameworks (“MOF”). This enables users of our products to dehumidify, evaporative cool, and harvest atmospheric water in both humid and arid climates.

Current conventional air conditioners condense water vapor into liquid as part of the cooling process, but that condensation process generates significant heat working contrary to the desired outcome, which is to dehumidify and cool a space. The AirJoule unit eliminates condensation on the evaporators in current conventional air conditioning systems, using a twin-chamber design in which both chambers contain MOF material, a novel desiccant material that has differentiated adsorption properties. Each chamber takes turns either removing moisture from the air or regenerating the MOF for reuse.

The impact of air conditioning on our planet cannot be understated. With over 40% of building energy demand coming from space cooling and a projected 2/3 of the world’s households having air conditioning in just 20 years according to the EIA, we believe that the world needs a better, lower-energy and lower-cost solution to meet these needs. We believe we are primed to transform the HVAC industry through our new technology, which represents a significant potential for improvement upon the energy efficiency of current conventional HVAC applications, as well as a potential source of potable water. Our AirJoule unit enables evaporative cooling using its own water harvested from air in regions where current conventional HVAC systems are typically less effective and is designed to reduce electrical consumption by as much as 75% than any other currently existing HVAC or atmospheric water-generating system. Our AirJoule system is expected to be up to 4 times more efficient (Coefficient of Performance (“COP”)) than existing conventional vapor compression dehumidification systems and up to 10 times more efficient than desiccant dehumidifiers. The energy cost savings derived by using an AirJoule dehumidifier are expected to have a payback period of as low as 1.5 years. The table below sets forth a comparison of conventional water-generating, dehumidification and cooling systems to the expected/potential performance of our AirJoule unit.

Atmospheric Water Harvesting

According to the World Resources Institute, 25% of the global population lives in countries facing extremely high water stress, with as many as four billion people already exposed to water stress conditions for at least one month per year. As a result of the rising degradation and disappearance of natural ecosystems that provide clean water and alleviate floods and other risks, the World Resources Institute estimates that demand for water will increase by up to 30% by 2050. The map below reflects the projected ratio of water withdrawals to water supply by country in 2040.

Atmospheric water harvesting, the process of generating potable water from the humidity in the air, has emerged as a promising solution to address the issue of water scarcity. Atmospheric water harvesting is a new and rapidly developing technology, and we believe that our foundational patents, proven pre-production and unique AirJoule unit uniquely position us to capture a meaningful amount of the growth in this evolving sector.

Our Solutions and Technology

What AirJoule Does

Our goal is to help solve two of the world’s most problematic issues with our AirJoule technology: increasing demand for comfort cooling and rising water stress. The AirJoule unit uses new technology that enables the atmosphere to become an accessible source of renewable thermal energy and a potential source of potable water at costs as low as half a cent per liter. The AirJoule unit efficiently harvests water vapor from the air, with a COP of up to 15, and is designed to consume as much as 75% less electricity than other currently-existing HVAC or water-generating systems while providing a potential source of potable water and air conditioning at a fraction of the current cost of traditional HVAC systems. We estimate that our AirJoule technology will reduce dehumidification costs for buildings by nearly 50%. We anticipate that we will complete a production-ready prototype of our AirJoule unit by the end of the fourth quarter of 2023 that will deliver up to 360 liters of water per day at 60-90 WH/L while simultaneously dehumidifying the air around the unit.

How It Works

AirJoule solves the issues of energetics, transformation of the latent heat of energy held in water vapor in the atmosphere to (1) potentially potable water, (2) dehumidified air, and (3) cooling, as shown above. Our proprietary pressure swing system integrates adsorption and desorption functions, so the heat of adsorption can be used to assist desorption under vacuum, eliminating the need for additional energy. In one chamber, outside air is passed over the paper-thin film of MOF, pulling water vapor into the material’s nano-sized pores. The heat that is generated from adsorbing water vapor is then transferred to the other chamber to help release water previously captured in the pores. A light vacuum pressure helps regenerate the MOF. Once the high-capacity MOF is regenerated, the twin chambers reverse their functions and the cycle repeats, avoiding the need to add heat or cooling to the process. By balancing the heat transfer between chambers, the system works to minimize energy consumption and allows the AirJoule system to continuously operate at ambient temperature, adding no extra load on an air conditioning unit. The result we have observed is a dramatic reduction in energy and cost, the production of water and the reduction of CO2 emissions as compared to conventional HVAC systems.

AirJoule operates as follows:

				Humid air is drawn into the open chamber;
				Proprietary MOF-coated contactors adsorb the water vapor in the open chamber;
				The heat of adsorption is transferred to a closed chamber to assist with desorption;
				Proprietary air pump draws vacuum on the closed chamber;
				Proprietary vacuum compressor pulls water vapor from the contactors in the closed chamber and slightly pressurizes it;
				Proprietary condenser produces pure water; and
				The alternating cycle between chambers occurs every 5 minutes.

Our current prototype of the AirJoule unit delivers up to 200 liters of water per day at 130 WH/L. We anticipate that our production-ready prototype will be able to deliver up to 360 liters of water per day at 60-90 WH/L.

Benefits of AirJoule

• Harnessing Clean energy: The AirJoule unit enables the atmosphere to be an accessible source of renewable thermal energy in a range of applications.

• Reduced Cost: The AirJoule unit is estimated to cost less than half of the upfront cost of conventional dehumidification systems while using significantly less electricity.

• Water: We anticipate that we will complete a production-ready prototype of our AirJoule unit by the end of the fourth quarter of 2023 that will deliver up to 360 liters of water per day; as low as 60-90 WH/L at costs as low as a half cent per liter.

• Reduced Electricity Use: The AirJoule system is designed to utilize up to 75% less electricity than current HVAC and water-generating systems.

• COP: The AirJoule unit significantly reduces, and in some cases can eliminate, the need for refrigerants to provide comfort cooling, and we anticipate that it will achieve a coefficient of performance (“COP”) as high as 15 versus the COP of 3 to 3.5 for traditional vapor compression direct expansion air conditioning systems.

• Climates: The AirJoule unit works in all climates, including humid and arid climates.

129

Table of Contents

• Retrofitting: Because of its compact size, the AirJoule unit easily integrates with current, conventional HVAC air handler units and ducting, making the AirJoule unit ideal for retrofitting existing HVAC installations and not just for new construction.

• Size: The AirJoule unit is compact, at roughly one-third the size of, and approximately 40% lighter than, a conventional HVAC system.

• Other Potential Applications: We have also filed a patent application for a water heating system that incorporates the AirJoule that we anticipate will achieve a COP as high as 7.1 versus the COP of 1 to 3.2 for traditional water heaters with electric resistive elements and heat pumps, respectively.

Key Components

Our AirJoule technology utilizes a proprietary desiccant, called a MOF. MOFs are a class of crystalline materials with ultrahigh porosity and enormous internal surface area.

We have engineered a proprietary MOF (“MTMOF1”) that is coated onto aluminum contactors, one of four key components of our AirJoule unit. In an AirJoule system, the MOF-coated aluminum contactors are placed into twin chambers that are open to incoming humid air in one cycle and closed in an alternate cycle, thus, the system can recover water vapor in the air by a method that does not generate condensation heat like traditional HVAC systems. For this reason, the AirJoule unit is able to exert the same dehumidifying effect with approximately 1/10th to 1/30th of the energy of current conventional dehumidifying systems. Our proprietary system captures the heat of adsorption and then uses this heat generated by adsorption without the need for additional heat input, yielding an efficient and robust water-harvesting system.

Our key component plan contemplates using our proprietary technology with mature manufacturing processes, alongside our global supplier relationship with BASF, to deliver MOF-coated contactors, vacuum and condenser systems to original equipment manufacturers (“OEMs”) for integration into existing HVAC systems, which we anticipate will substantially reduce the energy consumption and cost of such systems.

Growth Strategy and Outlook

The AirJoule system seeks to address two of the world’s most problematic issues: increasing demand for comfort cooling and rising water stress. We estimate that our TAM globally is approximately $455 billion, comprised of a TAM in the HVAC sector of approximately $355 billion(2) and a TAM in the atmospheric water harvesting sector of approximately $100 billion(3). We obtained the HVAC estimate from an independent report prepared by thebrainyinsights.com and the atmospheric harvesting estimate from conversations with water.org.

We aim to offer our products and services in global markets, particularly where demand for comfort cooling and water stress are highest. In light of our proprietary technology, we believe we are uniquely positioned to provide curated solutions that satisfy our customers’ needs and expectations within the HVAC and atmospheric water harvesting

sectors. Additionally, with several partnerships in place and a rapidly growing pipeline of new opportunities, we believe that we possess the potential for global manufacturing scalability at attractive margins. We anticipate that our existing partnerships with PNNL, BASF and CATL will help accelerate manufacturing of materials and components as well as provide product validation and commercialization. See “— Our Competitive Strengths — Our Partners.”

We believe that we have a capital efficient and highly scalable business model. We estimate that a capital expenditure investment of less than $50 million per production line to coat aluminum contactors will generate approximately $100 million in EBITDA per line for the Company. This estimate is based on a production line that is capable of coating one million contactors per year and contemplates sales of standard AirJoule units, which contain six coated contactors per unit. Our assessment that the manufacture and commencement of a production line will cost less than $50 million is based on estimates of equipment used in coating processes used by companies like BASF, assuming throughput of approximately one million contactors per year for a standard contactor measuring approximately two feet by two feet. We estimate that production costs will be approximately $187 per contactor, based on (a) the cost per pound of bulk aluminum foil used in each contactor (multiplied by two times to account for process cost and supplier margin) plus (b) an MOF cost of $50 per kilogram multiplied by the volume of one kilogram of MOF and (c) estimated coating process cost of $17 per contactor. We have assumed an average sales price of $287 per contactor, reflecting a gross margin of 35% per contactor incorporated into AirJoule units, resulting in a profit of $100 per contactor. Our estimate of the potential EBITDA generation of a single production line is calculated based on estimated production of one million contactors per line multiplied by the estimated profit of $100 per contactor. We anticipate that we will complete a production-ready prototype of our AirJoule unit by the end of the fourth quarter of 2023 and expect to commence our first production of market-ready AirJoule units in 2024. Following the Closing, we intend to self-fund future production lines.

We are party to a joint development agreement, dated as of September 27, 2022, with BASF for the production of engineered super-porous MOF materials to our specifications that are applied as a coating to AirJoule contactors to perform the energy and water-harvesting function (the “Joint Development Agreement”). Pursuant to the terms of the Joint Development Agreement, BASF will deliver sample MOF materials to us and we will pay BASF a fee, the amount of which will be mutually agreed with BASF prior to delivery of such sample. BASF is entitled to commission certain projects under the Joint Development Agreement to third-party toll manufacturers or its affiliates, provided that such third parties are bound by confidentiality obligations that are at least as stringent as those set forth in the Joint Development Agreement. Each party’s background intellectual property will remain the sole property of such party. Pursuant to the Joint Development Agreement, each party granted to the other a non-exclusive, royalty-free license to use such party’s background intellectual property to the extent necessary to fulfill its duties under the Joint Development Agreement. Any assignable intellectual property generated under the Joint Development Agreement solely by the employees of a particular party will be the exclusive property of said party. Any assignable intellectual property jointly generated under the Joint Development Agreement by employees of both parties (“Joint Inventions”) will be jointly and equally owned by us and BASF. BASF is entitled to manage any Joint Inventions, including with respect to the preparation, filing, prosecution and maintenance of patents with respect thereto, and the costs thereof will be shared equally by us and BASF. Each party to the Joint Development Agreement is entitled to exploit Joint Inventions on their own or with third parties without any compensation to the other party unless otherwise agreed with respect to such Joint Invention. However, no party is entitled to grant any access rights, including licenses, to third parties and no party is entitled to sell or pledge to third parties, or otherwise dispose of its share of, any Joint Invention or patent, in each case, without the prior written consent of the other party. For as long as BASF is able and willing to supply MOF materials developed under the Joint Development Agreement with a competitive performance profile at a competitive price, we are required, during the term of the Joint Development Agreement and for at least ten years thereafter, to procure all of our MOF materials exclusively from BASF on terms and conditions to be set forth in separately negotiated supply agreements. In the event that a separate commercial agreement between us and BASF cannot be reached, and we expect to use Joint Inventions in accordance with the Joint Development Agreement, we will be required to pay BASF a license fee based on MOF quantities manufactured and/or procured annually. The Joint Development Agreement will terminate on September 27, 2025. Either party may terminate the Joint Development Agreement prior to September 27, 2025 if the other party substantially breaches or fails to comply with any provisions of the Joint Development Agreement and does not cure such breach or failure to comply within 30 days of receipt of notice of such default from the non-defaulting party. Additionally, BASF is entitled to terminate the Joint Development Agreement for convenience upon three months’ prior written notice to us. BASF has successfully produced our proprietary MOF for our prototypes and is now scaling for mass production. We anticipate that we will expand our ongoing development agreement with BASF to include global manufacturing and supply.

CATL US Joint Venture. According to a recent report published by SNE Research, CATL was the world’s largest lithium-ion battery manufacturer in 2022 based on market share (calculated based on sales and shipments). On October 27, 2021, we entered into a joint venture with CATL US Inc. (“CATL US”), an affiliate of CATL, pursuant to which we and CATL US formed CAMT Climate Solutions Ltd., a limited liability company organized under the laws of Hong Kong (“CAMT”). We and CATL US both own 50% of CAMT’s issued and outstanding shares.

Table of Contents

Pursuant to the Amended and Restated Joint Venture Agreement for CAMT, entered into on September 29, 2023 (the “A&R Joint Venture Agreement”), we and CATL US have each agreed to contribute $6 million to CAMT. Of this $6 million, we expect to make an initial contribution of $2 million prior to December 31, 2023, with the remaining $4 million contributed over the next three years based on a business plan and operating budgets to be agreed between us and CATL US. Any additional financing beyond the initial $12 million will be subject to the prior mutual agreement of Montana and CATL US. CAMT is managed by a four-member board of directors, with two directors (including the chairman) designated by CATL US and two directors (including the vice chairman) designated by Montana. In the event of an equal vote, the chairman may cast the deciding vote. Certain reserved matters, including debt issuances exceeding $5 million in a single transaction or in aggregate within a fiscal year, amendments to CAMT’s constitutional documents the annual financial budget of CAMT, and any transaction between CAMT and CATL US or Montana in an amount exceeding $10 million in a single transaction or in aggregate within a fiscal year, require the unanimous vote of both CATL US and Montana or all directors.

The purpose of our joint venture with CATL US is to commercialize our AirJoule technology in Asia and Europe and, pursuant to the A&R Joint Venture Agreement, CAMT has the exclusive right to commercialize our AirJoule technology in those territories. Subject to the oversight of CAMT’s board, CATL US is responsible for managing the day-to-day operations of CAMT (including the nomination and replacement of the Chief Executive Officer of CAMT), and is responsible for providing CAMT and any subsidiaries formed by CAMT with, among other things, administrative services, supply chain support, assistance in obtaining required permits and approvals, and assistance in purchasing or leasing land and equipment. Subject to certain exceptions described in the following sentence, we have granted to CAMT an exclusive, royalty-free license to use certain existing and future-developed intellectual property rights that we own or license to commercialize our AirJoule technology in Asia and Europe, and we have agreed to provide CAMT with certain services at no charge to enable it to utilize such intellectual property rights. Notwithstanding the foregoing, we are not obligated to provide to CAMT or its subsidiaries any intellectual property rights or services if doing so would violate any applicable law or result in a breach of any contract to which we are a party, or if doing so would enable CAMT or its subsidiaries to access or obtain the proprietary formula(s) for our existing or future-developed metal-organic frameworks or any related proprietary method of manufacture or application that we develop.

Except as we otherwise may agree with CATL US, any intellectual property rights relating to the AirJoule technology that (i) we co-develop with CATL US, (ii) either we or CATL US co-develop with CAMT, or (iii) CAMT develops, in each case, will be exclusively owned by CAMT, with a perpetual, non-exclusive, worldwide license to Montana. Such license will be royalty free for the purpose of improving the AirJoule technology and will bear a royalty (in an amount to be negotiated in good faith between CAMT and Montana) for other uses.

Pursuant to the A&R Joint Venture Agreement, it is CAMT’s policy to declare and pay dividends as and when CAMT has net profits. Subject to certain conditions, we and CATL US have agreed to cause CAMT’s board of directors to declare and pay dividends in accordance with the laws of Hong Kong. So long as both we and CATL US have contributed 50% of CAMT’s share capital, CAMT generally will distribute net profits on a 50/50 basis, but each distribution will be adjusted such that CATL US receives 60% (and Montana receives 40%) of all net profits generated by CAMT and its subsidiaries from sales in China (excluding Hong Kong, Macau, and Taiwan). Neither we nor CATL US may transfer our interests in CAMT without the prior consent of the other.

The A&R Joint Venture Agreement has an indefinite term and, absent the occurrence of certain events set forth therein (e.g., an uncured material breach), no party may unilaterally terminate the A&R Joint Venture Agreement. If the A&R Joint Venture Agreement is terminated for any reason, all intellectual property licenses that we have granted to CAMT and its subsidiaries will terminate and revert to Montana and all intellectual property licenses that CATL US has granted to CAMT and its subsidiaries, if any, will terminate and revert to CATL US. Further, in the event of termination, we will own all intellectual property rights owned by CAMT prior to termination, with CATL US receiving a perpetual, royalty-free, non-exclusive license to use such intellectual property rights in Asia and Europe.

In addition to the terms described above, the A&R Joint Venture Agreement contains customary representations and warranties, as well as provisions relating to, among other things, director and officer insurance, information rights of shareholders, indemnification, and related-party transactions.

CATL Investment Agreement. Contemporary Amperex Technology USA Inc., an affiliate of CATL (“CATL USA” and, together with CATL and CATL US, the “CATL Parties”) is one of our members. On September 29, 2023, we entered into an Investment Agreement (the “Investment Agreement”) with XPDB and the CATL Parties, pursuant to which the CATL Parties agreed, among other things, that they will not, directly or indirectly, (i) acquire any additional units of Montana, (ii) seek election to, or to place a representative on, our board of managers or the Post-Combination Company Board, or (iii) acquire any securities of the Post-Combination Company if, following such acquisition, the CATL Parties and their affiliates would hold, in the aggregate, an interest in the Post-Combination Company of greater than 9.8% on either an economic or voting basis (the “CATL Ownership Limit”). In the event the CATL Parties and their affiliates exceed the CATL Ownership Limit, the CATL Parties have agreed, following written notice from the Post-Combination Company, to divest within five business days such number of Post-Combination Company securities as shall be necessary to cause the CATL Ownership Limit not to be exceeded. In addition, at any time the CATL Ownership Limit is exceeded, the CATL Parties have agreed to vote any voting power they hold in excess of 9.8% in accordance with the recommendation of the Post-Combination Company Board.

Pursuant to the Investment Agreement, the CATL Parties agreed that they will not, and will cause their affiliates not to, access, obtain, or seek to access or obtain our or the Post-Combination Company’s trade secrets, know-how, or other confidential, proprietary, or competitively sensitive information (excluding any such information that we are obligated to provide to CATL US, CAMT, or CAMT’s subsidiaries pursuant to the A&R Joint Venture Agreement described above), including by reverse engineering, or seeking to reverse engineer, any of our products.

CATL has informed us that it intends to exit a portion of its equity investment in Montana, in which CATL USA owned approximately 5% as of June 30, 2023, in favor of focusing on the CAMT joint venture. To that end, we have agreed in the Investment Agreement to use our reasonable best efforts to assist CATL USA in selling, prior to the consummation of the Business Combination, units of Montana representing at least 2% of our issued and outstanding units at a price per unit that is not materially lower than the price per unit implied by the valuation of Montana in connection with the Business Combination. In so assisting CATL USA, we are not obligated to incur any expenses or grant any concessions, nor are we obligated to prioritize any sale by CATL USA over our own capital raising or financing activities.

The Investment Agreement contains customary representations and warranties and may be terminated only with the written consent of the parties thereto.

Our Patents

We hold and license foundational patent applications relating to atmospheric latent energy and water harvesting that uniquely position us to capture and drive a meaningful amount of the growth in the rapidly developing atmospheric water harvesting sector. In the first quarter of 2021, we obtained an exclusive worldwide license from PNNL with respect to its self-regenerating dehumidifier technology and executed a strategic project partnership agreement with PNNL to further develop enhancements to the technology. We also have two master patent PCT applications and have filed patent applications in 44 countries relating to the AirJoule unit. Our patent applications cover various technologies and components, including latent energy and water harvesting systems, evaporative cooling and water recapture systems, evaporative heat pump systems, water heating systems, low relative humidity drying systems, pre- and mid-cool integration coils, advanced vacuum pump systems, isothermal condenser design, gate and seal systems and methods, HVAC systems with AirJoule integration and microchannel harvesters and contactors.

Our Management

Our management team has a combined 140+ years of experience across commercialization, finance, operations and research and is supported by some of the nation’s leading scientists in the area of atmospheric water harvesting. We believe they are well-positioned to lead us in the journey ahead.

Sales and Marketing

Many companies have become increasingly conscious of their environmental footprint as a result of expectations placed upon them by their customers, investors and other stakeholders. The Governance & Accountability Institute found that in 2022, 96% of S&P 500 companies and 81% of Russell 1000 companies published reports to their investors describing their environmental, social, and governance commitments. Companies are developing strategies to adapt their business models in response to customer and investor demands that these businesses transition to leveraging sustainable, clean energy and invest in solutions to global warming and water scarcity. We believe the AirJoule system will actively help our anticipated customers manage their sustainability profiles and derive real commercial and operational benefits from doing so. As an early participant in the rapidly growing ecosystem of atmospheric water harvesting, we believe we are well-positioned to capture and drive a meaningful amount of growth in the sector. As atmospheric water harvesting technology continues to advance, we expect a corresponding growth in demand for the products resulting from the deployment of our AirJoule technology. We believe the AirJoule system harvests water from the air more effectively than any other technology that is available on the market today and that the AirJoule system can potentially secure access to and make abundant potable water for common use almost anywhere on the planet, particularly in water-scarce regions. We have also positioned Montana to be a tier-1 supplier to these HVAC manufacturers, instead of competing for their end-market customers. We believe our partnerships will enable Montana to be a reliable tier-1 supplier to the HVAC OEMs on a global basis.

We aim to offer our products and services in global markets where demand for comfort cooling and water stress are highest. We also intend to deliver proprietary MOF-coated contactors, proprietary condensers, proprietary air pumps and proprietary vacuum compressors to OEMs for integration into existing HVAC systems, which we anticipate will substantially reduce the energy consumption and cost of such systems.

Manufacturing

In the first quarter of 2023, we completed the fourth prototype of our AirJoule unit, which delivers up to 200 liters per day at 130 WH/L of water. We anticipate that we will complete a production-ready prototype of our AirJoule unit by the end of the fourth quarter of 2023 that will deliver up to 360 liters of water per day at as low as 60-90 WH/L, depending on humidity. We expect Montana will also be a tier-1 supplier to HVAC manufacturers, with our partnerships enabling Montana to be a reliable tier-1 supplier to the HVAC OEMs on a global basis. We expect to commence our first production of market-ready AirJoule units in 2024, and anticipate that our international partnerships, including our joint venture, CAMT, will enable us to transition to mass production quickly and efficiently. We also believe these partnerships will help in the validation and commercialization of our products.

Research and Development

Our management team knows the ability to grow and maintain a leading position in our industries depends on our continuing investment in research and development activities. The goals of our research and development efforts include continuing to optimize our AirJoule systems and corresponding technology and protecting and developing our intellectual property rights in our product and technology. Our management team is supported by some of the nation’s leading scientists in the atmospheric water harvesting sector.

We rely on non-disclosure agreements with employees, independent contractors, customers, and other third parties to protect our intellectual property and proprietary rights. Circumstances outside our control could pose a threat to our intellectual property rights. For more information, see “Risk Factors — Risks Related to Intellectual Property and Technology — Our patent applications may not result in issued patents, and our issued patents may not provide adequate protection, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours.”

Competition

HVAC

The production and sale of HVAC equipment is highly competitive. HVAC manufacturers primarily compete on the basis of price, depth of product line, product efficiency and reliability, product availability and warranty coverage. We believe that our largest competitors in the HVAC market will include Carrier Corporation (a division of United Technologies Corporation), Trane Inc. (a wholly-owned subsidiary of Ingersoll-Rand Company Limited), Lennox International, Inc., Mitsubishi Electric Corporation and Rheem Manufacturing Company, among others. We have positioned Montana to be a tier-1 supplier to these HVAC manufacturers, instead of competing for their end-market customers. We believe our partnerships will enable Montana to be a reliable tier-1 supplier to the HVAC OEMs on a global basis. A number of factors affect competition in the HVAC market, including the development and application of new technologies and an increasing emphasis on the development of more efficient HVAC products, such as our AirJoule unit. In addition, new product introductions are an important factor in the market categories in which our products will compete. Some of our competitors are large and have significantly greater financial, marketing and technical resources than we do. Although we believe we will be able to compete successfully in our markets, there can be no assurance that we will be able to do so in the future.

Atmospheric Water Harvesting

Atmospheric water harvesting, the process of generating water from the humidity in the air, is a new and rapidly developing technology that has emerged as a promising solution to address the issue of water scarcity. Given the emerging nature of the atmospheric water harvesting industry, there are a number of companies developing partial solutions that may be similar to parts of the AirJoule system. However, we believe that the majority of the other companies developing similar solutions do not capture the full range of functions of the AirJoule system. We believe that our foundational patents and proprietary AirJoule unit uniquely position us to capture and drive a meaningful amount of the growth in this evolving sector. We expect competition to intensify in the future as the market for atmospheric water harvesting matures.

136

Table of Contents

Seasonality

We believe that weather patterns may impact the demand for our AirJoule units. For example, hot weather may cause existing HVAC units to fail, driving customers to accelerate replacement of existing units. Similarly, unseasonably mild weather may diminish customer demand for both commercial and residential HVAC replacement and repairs. Weather may also impact installation during periods of inclement weather as fewer units are installed due to dealers being delayed or forced to shut down their operations.

Employees

As of June 30, 2023, we had fifteen employees and contractors, fourteen of whom are located in the United States and one of whom is located in the United Kingdom. None of our employees or contractors are represented by a labor union. We have not experienced any work stoppages and believe we maintain good employee and contractor relations.

Facilities

We currently lease our principal executive office in Ronan, Montana. This leased facility consists of 4,000 square feet of office space under a lease. This facility accommodates our pilot product development and engineering teams, operations, marketing, finance and administrative functions. We believe that our office and pilot prototyping space is adequate for our needs for the immediate future and, should we need additional space in connection with our expansion plans, we believe we will be able to obtain additional space on commercially reasonable terms.

Government Regulation

Our business activities are subject to various laws, rules, and regulations of the United States. Compliance with these laws, rules, and regulations has not had a material effect upon our capital expenditures, results of operations, or competitive position, and we do not currently anticipate material capital expenditures to comply with applicable environmental, health and safety laws and regulations. Nevertheless, compliance with existing or future governmental regulations, including, but not limited to, those pertaining to international operations, export controls, business acquisitions, consumer and data protection, environmental protection, employee health and safety, and taxes, could have a material impact on our business in subsequent periods. Please see “Risk Factors” for a discussion of these potential impacts.

Legal Proceedings

We have not been, are not currently a party to, nor are we aware of, any legal proceeding or claim which, in the opinion of management, is likely to materially adversely affect our business or financial results or condition. From time to time, we may be subject to various claims, lawsuits and other legal and administrative proceedings that may arise in the ordinary course of business. Some of these claims, lawsuits and other proceedings may range in complexity and result in substantial uncertainty; it is possible that they may result in damages, fines, penalties, non-monetary sanctions or relief.

Company Overview

We are an atmospheric renewable energy and water harvesting technology company that aims to provide energy and cost-efficient, sustainable dehumidification, evaporative cooling and atmospheric water generation. As compared to currently existing HVAC systems, our AirJoule technology is designed to reduce energy consumption, minimize/eliminate harmful refrigerants, and generate material cost efficiencies. AirJoule is a climate solution technology that harvests the untapped supply of renewable thermal energy in water vapor in the atmosphere in an effort to provide significant energy efficiency gains in HVAC and a potential source of potable water. We are focused on scaling manufacturing through global joint ventures and deploying AirJoule units worldwide as a key part of the solution to address global warming and water scarcity.

Growth Strategy and Outlook

The AirJoule system seeks to address two of the world’s most problematic issues: increasing demand for comfort cooling and rising water stress. We estimate that our TAM globally is approximately $455 billion, comprised of a TAM in the HVAC sector of approximately $355 billion and a TAM in the atmospheric water harvesting sector of approximately $100 billion. We obtained the HVAC estimate from an independent report prepared by thebrainyinsights.com and the atmospheric harvesting estimate from conversations with water.org.

We aim to offer our products and services in global markets where demand for comfort cooling and water stress are highest. In light of our proprietary technology, we believe that we are uniquely positioned to provide curated solutions that satisfy our customers’ needs and expectations within the HVAC and atmospheric water harvesting sectors. Additionally, with several partnerships in place and a rapidly growing pipeline of new opportunities, we believe that we possess the potential for global scalability at attractive margins. We anticipate that our existing partnerships with PNNL, BASF and CATL will help accelerate manufacturing of materials and components as well as provide product validation and commercialization. See “— Our Competitive Strengths — Our Partners.”

We believe that we have a capital efficient and highly scalable business model. We estimate that a capital expenditure investment of less than $50 million for production lines to coat aluminum contactors will generate approximately $100 million in EBITDA per line for the Company. We anticipate that we will complete a production-ready prototype of our AirJoule unit by the end of the fourth quarter of 2023 and expect to commence our first production of market-ready AirJoule units in 2024. Following the Closing, we intend to self-fund future production lines. For additional details regarding the basis upon which the Company’s estimates with respect to capital expenditures and EBITDA generation are made, including the material assumptions underlying such estimates, please see the section entitled “Information about Montana — Growth Strategy and Outlook”.

Comparability of Financial Information

Montana’s results of operations and statements of assets and liabilities may not be comparable between periods as a result of the Merger.

Table of Contents

Merger and Public Company Costs

Montana entered into the Merger Agreement with XPDB on June 5, 2023. Pursuant to the Merger Agreement, and assuming a favorable vote of XPDB’s shareholders, Merger Sub, a newly formed subsidiary of XPDB, will be merged with and into Montana. Upon consummation of the Merger, the separate corporate existence of Merger Sub will cease and Montana will survive the Merger as a wholly-owned subsidiary of XPDB. Montana will be deemed the accounting predecessor and the combined entity will be the successor SEC registrant, meaning that Montana’s financial statements for previous periods will be disclosed in the registrant’s future periodic reports filed with the SEC.

The Merger is anticipated to be accounted for as a reverse recapitalization. Under this method of accounting, XPDB will be treated as the acquired company for financial statement reporting purposes. The most significant change in the successor’s future reported financial position and results are expected to be an estimated increase in cash (as compared to Montana’s consolidated balance sheet at December 31, 2022) of between approximately $69.2 million, assuming maximum shareholder redemptions permitted under the Merger Agreement, and $96.0 million, assuming no shareholder redemptions. Total non-recurring transaction costs are estimated at approximately $4.3 million, of which Montana expects the substantial majority to be capitalized as an offset to equity. See “Unaudited Pro Forma Condensed Combined Financial Information.”

As a consequence of the Merger, Montana will become the successor to an SEC-registered and Nasdaq-listed company, which will require Montana to hire additional personnel and implement procedures and processes to address public company regulatory requirements and customary practices. Montana expects to incur additional annual expenses as a public company for, among other things, directors’ and officers’ liability insurance, director fees and additional internal and external accounting and legal and administrative resources, including increased audit and legal fees.

Key Financial Definitions/Components of Results

Revenue

Montana anticipates that it will earn revenue from the sale of various key components such as MOF-coated contactors that will be used in the assembly of AirJoule systems.

Operating Expenses

We classify our operating expenses into the following categories:

• Research and development expense. Research and development expense includes internal personnel, parts, prototypes and third-party consulting costs related to preliminary research and development of Montana’s products.

• General and administrative expense. General and administrative expense consists primarily of personnel-related expenses for our executives, consultants and advisors. These expenses also include non-personnel costs, such as rent, office supplies, legal, audit and accounting services and other professional fees.

• Sales and marketing expense. Sales and marketing expense consists primarily of business development professional fees, advertising and marketing costs.

• Depreciation expense: Depreciation expense consists of depreciation of Montana’s vehicles.

Critical Accounting Estimates

The preparation of financial statements in conformity with GAAP requires Montana’s management to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses during the reported periods. Montana does not currently have any critical accounting estimates that could have a material impact on their financial statements. Montana has other key accounting policies, which involve the use of estimates, judgments and assumptions that are significant to understanding its results, which are described in Note 3 to Montana’s consolidated financial statements as of and for the years ended December 31, 2022 and 2021 appearing elsewhere in this proxy statement/prospectus.

Fair Value of Financial Instruments

Fair value is the price that would be received to sell an asset, or the amount paid to transfer a liability in an orderly transaction between market participants at the measurement date. There is a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The Company classifies fair value balances based on the observability of those inputs. The three levels of the fair value hierarchy are as follows:

		Level 1 —		Inputs based on unadjusted quoted market prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
		Level 2 —		Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active or for which all significant inputs are observable or can be corroborated by observable market data.
		Level 3 —		Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are both unobservable for the asset and liability in the market and significant to the overall fair value measurement.

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. The Company establishes the fair value of its assets and liabilities using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and establishes a fair value hierarchy based on the inputs used to measure fair value. The recorded amounts of certain financial instruments, including accounts receivable, accounts payable, accrued expenses, debt at fixed interest rates and other liabilities approximate fair value due to their relatively short maturities.

Share-Based Compensation

The Company accounts for share-based compensation arrangements granted to employees in accordance with ASC Topic 718, “Compensation: Stock Compensation,” by measuring the grant date fair value of the award and recognizing the resulting expense over the period during which the employee is required to perform service in exchange for the award. Equity-based compensation expense is only recognized for awards subject to performance conditions if it is probable that the performance condition will be achieved. The Company accounts for forfeitures when they occur.

Liquidity and Capital Resources

Montana’s primary sources of liquidity have been cash from contributions from founders or other investors. Montana had an accumulated deficit of $9.1 million and $5.8 million as of June 30, 2023 and December 31, 2022, respectively. As of June 30, 2023, Montana had $3.5 million in cash and working capital of $1.5 million. As of December 31, 2022, Montana had $5.2 million in cash and working capital of $5.1 million.

Montana 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, capital expenditures and other general corporate services. Montana’s primary working capital requirements are for project execution activities including purchases of materials, services and payroll which fluctuate during the year, driven primarily by the timing and extent of activities required on new and existing projects. Montana’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 development of its technology and the development of market and strategic relationships with other businesses and customers. Consequently, its continued existence is dependent upon its ability to obtain additional capital to support its ongoing operations.

Montana has had, and expects that it will continue to have, an ongoing need to raise additional capital from outside sources to fund the further development of its initial product, the commercialization of its product and further expand its operations and business. If Montana is unable to raise additional capital when desired, its business, financial condition and results of operations would be harmed. Successful transition to attaining profitable operations depends upon achieving a level of revenue adequate to support the Post-Combination Company.

Montana expects that working capital requirements will continue to be funded through a combination of cash on hand, further issuances of securities, and/or the incurrence of indebtedness. In connection with its business plan, management anticipates additional increases in operating expenses, research and development costs and capital expenditures relating to the development and commercialization of its products. Montana intends to finance these expenses with further issuances of debt or equity securities to the extent that there is insufficient cash from the Business Combination. Thereafter, Montana expects it will need to raise additional capital and generate revenues to meet long-term operating requirements. If Montana raises additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our equityholders could be significantly diluted, and these newly issued securities may have rights, preferences or privileges senior to those of existing equityholders. If Montana raises additional funds by obtaining loans from third parties, the terms of those financing arrangements may include negative covenants or other restrictions on our business that could impair our operating flexibility and also require us to incur interest expense.

As a result of the above, in connection with the Company’s assessment of going concern considerations in accordance with the FASB ASU 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the Company’s management has determined that its liquidity condition raises substantial doubt about its ability to continue as a going concern through twelve months from the date these consolidated financial statements are available to be issued. These consolidated financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

Contractual Obligations and Commitments

In October 2021, the Company entered into a patent license agreement with a third party whereby the third party granted the Company rights to use certain of its patents in exchange for an upfront payment and royalties based on a percentage of net sales until such patents expire. In connection with this, the Company agreed to a minimum royalty amount of $50,000 for the year ended December 31, 2022 which has been accrued by the Company in the accompanying condensed balance sheets. During the three and six months ended June 30, 2023 the Company expensed $25,000 and $75,000, respectively, relating to this commitment. At June 30, 2023, $75,000 was accrued by the Company in the accompanying condensed balance sheet. Future minimum royalties as of June 30, 2023 are as follows:

Remaining of 2023	$	75,000
2024		250,000
2025 and each year through the date the patents expire		300,000

Off balance sheet arrangements

As of the date of this proxy statement/prospectus, Montana does not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on its financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors. The term “off-balance sheet arrangement” generally means any transaction, agreement or other contractual arrangement to which an entity unconsolidated with Montana is a party, under which it has any obligation arising under a guarantee contract, derivative instrument or variable interest or a retained or contingent interest in assets transferred to such entity or similar arrangement that serves as credit, liquidity or market risk support for such assets.

Currently Montana does not engage in off-balance sheet financing arrangements.

Emerging Growth Company Status

Montana is an emerging growth company as defined in the JOBS Act. The JOBS Act permits companies with emerging growth company status to take advantage of an extended transition period to comply with new or revised accounting standards, delaying the adoption of these accounting standards until they would apply to private companies. Montana has elected to use this extended transition period to enable it to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date 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, Montana’s financial statements may not be comparable to companies that comply with the new or revised accounting standards as of public company effective dates.

In addition, Montana intends to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an emerging growth company, Montana intends to rely on such exemptions, it is not required to, among other things: (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act; (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act; (iii) 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 (auditor discussion and analysis); and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer’s compensation to median employee compensation.

Montana will remain an emerging growth company under the JOBS Act until the earliest of (i) the last day of its first fiscal year following the fifth anniversary of the closing of the XPDB IPO, (ii) the last date of our fiscal year in which it has total annual gross revenue of at least $1.235 billion, (iii) the date on which it is deemed to be a “large accelerated filer” under the rules of the SEC with at least $700.0 million of outstanding securities held by non-affiliates or (iv) the date on which it have issued more than $1.0 billion in non-convertible debt securities during the previous three-years.

Our board of directors believes its administration of its risk oversight function has not negatively affected our board of directors’ leadership structure.

Compensation Committee Interlocks and Insider Participation

None of our executive officers currently serves, or in the past year has served, as a member of the board of directors or compensation committee (or other committee performing equivalent functions) of any entity that has one or more executive officers serving on our board of directors or compensation committee.

Code of Business Conduct and Ethics

Prior to the completion of the Business Combination, we will adopt a written code of business conduct and ethics that applies to our directors, officers and employees, including our 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 our corporate website at https://mt.energy/ upon the completion of the Business Combination. In addition, we intend to post on our website all disclosures that are required by law or Nasdaq listing standards concerning any amendments to, or waivers from, any provision of the code.

Narrative Disclosure to Summary Compensation Table

2022 Consulting Fees and Salaries

During 2022, Messrs. Jore and Gutke provided services to Montana in 2022 as independent contractors through MRJ, LLC (an entity partially owned by Mr. Jore) and Doxey Capital LLC (an entity owned by Mr. Gutke), respectively, and received consulting fees rather than base salaries in connection with such services. Mr. Gabig received a base salary from Montana in 2022 in connection with his services. The consulting fees or base salary (as applicable) payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. During 2022, Mr. Jore received a consulting fee of $20,000 per month, Mr. Gutke received a consulting fee of $20,000 per month, and Mr. Gabig received a base salary of $120,000 per year. The Summary Compensation Table above shows the actual consulting fees or base salary paid to each named executive officer in fiscal year 2022.

Equity Compensation

Each of Montana’s named executive officers currently hold Montana Options. In 2020, options to purchase 65,000 and 25,000 Montana Class C Common Units, respectively, were granted to Messrs. Jore and Gabig, and in 2021, an option to purchase 12,000 Montana Class C Common Units was granted to Mr. Gutke. The Montana Options granted to the named executive officers generally were fully vested upon grant and had per-unit exercise prices of $0.625 (for Messrs. Jore and Gabig) and $2.86 (for Mr. Gutke). No options or other equity awards were granted to Montana’s named executive officers in 2022.

In connection with the Business Combination, the Post-Combination Company intends to adopt the Incentive Plan in order to facilitate the grant of cash and equity incentives to directors, employees (including the named executive officers) and consultants of the Post-Combination Company and certain of its affiliates and the ESPP in order to provide the Post-Combination Company’s and its participating subsidiaries’ employees with the opportunity to purchase shares of Class A Common Stock through accumulated payroll deductions. We believe the Incentive Plan and ESPP will be key factors in the Post-Combination Company and its affiliates recruiting and retaining services of employees and other service providers, which is essential to the Post-Combination Company’s long-term success. It is expected that the Incentive Plan and ESPP will become effective upon the Closing, if they are approved by XPDB’s shareholders. For additional information about the Incentive Plan and ESPP, please see the sections titled “Proposal No. 6 — The Incentive Plan Proposal” and “Proposal No. 7 — The Employee Stock Purchase Plan Proposal” above.

Retirement Plan

Montana does not currently maintain, but the Post-Combination Company intends to establish a 401(k) retirement savings plan for its employees, including its named executive officers, who satisfy certain eligibility requirements. It is expected that the Post-Combination Company’s named executive officers will be eligible to participate in the 401(k) plan on the same terms as other full-time employees. The Code allows eligible employees to defer a portion of their compensation, within prescribed limits, through contributions to the 401(k) plan. The Post-Combination Company believes that providing a vehicle for tax-deferred retirement savings though a 401(k) plan adds to the overall desirability of its executive compensation package and further incentivizes its employees, including its named executive officers, in accordance with our compensation policies.

Employee Benefits and Perquisites

Montana does not currently maintain, but the Post-Combination Company intends to establish, health and welfare plans (including medical, dental and vision plans) for all of its full-time employees, including its named executive officers. We believe these benefits are appropriate and will provide a competitive compensation package to the Post-Combination Company’s named executive officers.

Montana provides Mr. Jore with a company-paid mobile phone, and pays a portion of the premiums for Mr. Jore’s health insurance coverage. Other than these benefits provided to Mr. Jore, Montana does not provide any perquisites to its named executive officers.

No Tax Gross-Ups

Montana does not make gross-up payments to cover its named executive officers’ personal income taxes that may pertain to any of the compensation or perquisites paid or provided by Montana.

The Eligible Equityholders will also have the opportunity to receive additional equity consideration (in each case, in accordance with their respective pro rata share) in the form of Earnout Shares only upon full completion of construction and operational viability (including all permitting, regulatory approvals and necessary or useful inspections) of new production capacity of Montana’s key components or assemblies based solely on demand from bona fide customer commitments evidenced by binding contracts (or in the sole discretion of a majority of the independent members of the Post-Combination Company Board, a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known pr ice or pr icing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA of more than $150,000,000, which shall be determined by a majority of the independent members of the Post-Combination Company Board in their sole discretion, equal to (i) the ratio of (x) (1) the Expected Annualized EBITDA less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000.

The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing.

Background of the Business Combination

The following is a brief summary of the background of these negotiations and a summary of the events leading up to the signing of the Merger Agreement and the key meetings, negotiations, discussions and actions by and between XPDB, Montana and their respective representatives that preceded the public announcement of the transaction; it does not purport to catalogue every conversation or interaction among representatives of XPDB, Montana and the other parties referenced below.

XPDB is a blank check company incorporated in Delaware on March 23, 2021 and formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses with the intent to focus specifically on a combination with a target business driving the electrical power grid transition, both on the supply and demand side. On the supply side, XPDB planned to target businesses including, but not limited to (i) renewable power generation; (ii) power technology, equipment and services companies that focus on the integration of intermittent renewables; and (iii) dispatchable energy transition infrastructure. On the demand side, XPDB planned to target businesses comprised of, but not limited to (i) data centers and data center management; (ii) blockchain infrastructure; and (iii) frontier technology infrastructure.

On December 9, 2021, XPDB engaged Barclays and BofA (together with Barclays, the “Underwriters”) to provide investment advisory services in connection with the XPDB IPO. Additionally, given Barclays’ experience with special purpose acquisition companies and familiarity with XPDB, as well as Barclays’ coverage capabilities and banking relationships, XPDB engaged Barclays on June 4, 2023 to provide capital markets advisory services in connection with its Business Combination with Montana. In this role, Barclays has assisted XPDB with preparing the materials to be presented in connection with the Business Combination and assisted in corporate capital planning and risk management for the Business Combination. Additionally, Barclays expects to assist XPDB in the coordination of presentations to and logistical communications with existing and prospective shareholders and other relevant parties. Barclays is not participating in the solicitation of proxies in connection with the Business Combination.

Barclays is entitled to receive a deferred underwriting fee in connection with its role as a joint bookrunner for the XPDB IPO in the amount of $6,037,500. Barclays is entitled to receive a capital markets advisory fee of $6 million (which amount will be credited against any deferred underwriting fee due to Barclays as provided above), as well as reimbursement of certain of its expenses related to its engagement. All of the fees described above are conditioned on the completion of the Business Combination. Effective June 20, 2023, BofA waived its right to receive a deferred underwriting fee in connection with its role as a joint bookrunner for the XPDB IPO in the amount of $4,025,000.

On March 30, 2021, the Sponsor purchased 5,750,000 Founder Shares for an aggregate purchase price of $25,000, or approximately $0.004 per share. Prior to the initial investment in XPDB of $25,000 by the Sponsor, XPDB had no assets, tangible or intangible. The per share price of the Founder Shares was determined by dividing the amount of cash contributed to XPDB by the number of Founder Shares issued. The number of Founder Shares issued was determined based on the expectation that the Founder Shares would represent 20% of the outstanding shares of common stock upon completion of the XPDB IPO. In November 2021, XPDB effected a stock dividend of 1,437,500 Founder Shares resulting in an aggregate of 7,187,500 Founder Shares. In July 2021, the Sponsor transferred 30,000 Founder Shares to each of Paul Dabbar, Paul J. Gaynor, Scott Widham (XPDB’s independent directors) and an additional independent director nominee for a total of 120,000 Founder Shares. Later in November 2021, the Sponsor repurchased 30,000 Founder Shares from the former independent director nominee. In exchange for the Anchor Investors’ participation in the XPDB IPO and Private Placement, (i) XPDB agreed to sell to the Anchor Investors, and the Anchor Investors agreed to purchase, on the date of an initial business combination, up to 1,078,125 Founder Shares (subject to reduction based on the Anchor Investors’ ownership of XPDB Class A Common Stock at the time of any stockholder vote with respect to the initial business combination), and (ii) the Sponsor agreed to forfeit to XPDB for no consideration a number of Founder Shares equal to the number of Founder Shares sold to the Anchor Investors as provided above.

The registration statement for the XPDB IPO was declared effective on December 9, 2021. On December 14, 2021, XPDB consummated the XPDB IPO of 28,750,000 units, which included the full exercise of the underwriters’ option to purchase an additional 3,750,000 units, at a price of $10.00 per unit, generating gross proceeds of $287,500,000 before underwriting discounts and expenses. Each unit consisted of one share of XPDB Class A Common Stock and one-half of one redeemable warrant. Each whole XPDB public warrant entitles the holder thereof to purchase one share of XPDB Class A Common Stock at a price of $11.50 per share, subject to certain adjustments. Of the proceeds received from the consummation of the XPDB IPO (including the sale of the Over-Allotment Units) and the Private Placement purchases by the Sponsor and the Anchor Investors, $290,400,000 (or $10.10 per unit sold in the public offering) was deposited in the Trust Account.

Table of Contents

Concurrently with the completion of the XPDB IPO, the Sponsor and the Anchor Investors purchased an aggregate of 11,125,000 Private Placement Warrants at a price of $1.00 per warrant for an aggregate purchase price of approximately $11,1250,000. Each whole Private Placement Warrant entitles the holder thereof to purchase one share of XPDB Class A Common Stock at a price of $11.50 per share, subject to certain adjustments. Prior to the consummation of the XPDB IPO, neither XPDB, nor anyone acting on its behalf, contacted any prospective target business or had any substantive discussions, formal or otherwise, with respect to a business combination with XPDB.

Between December 14, 2021 and May 5, 2023, the date on which XPDB entered into exclusive negotiations with Montana (as further described below), the XPDB Board and XPDB’s management identified more than 210 potential target companies in various sectors including, but not limited to renewable power generation; power technology, equipment and services with a focus on the integration of intermittent renewables; dispatchable energy transition infrastructure; data centers and data center management; blockchain infrastructure; and frontier technology infrastructure. XPDB and its representatives initiated contact with or were contacted by various representatives regarding more than 25 of such potential target businesses for further evaluation. XPDB engaged in varying levels of discussions, due diligence, evaluation, analysis and negotiations with these 25 target businesses, including participating in management meetings with 10 of the 25 target businesses. The level of diligence varied based on interest from, and due diligence access granted by, the potential targets; XPDB’s and its representatives’ beliefs as to which potential targets would best satisfy XPDB’s key criteria for a business combination target; the receptivity to, and preparedness of, the potential targets with respect to a business combination and the terms on which a target was willing to consider a potential business combination. Following such due diligence, and at various points in time, XPDB decided to discontinue discussions with each of the potential targets, other than Montana, Company A, Company B, Company C and Company D (each as defined and described below), for one or various reasons, including, among other reasons, business maturity, market acceptance of technological advancements, current, or a near-term path to, revenue and profitability, growth prospects, valuation expectations or relative attractiveness to other opportunities. The XPDB Board and XPDB’s management met bi-weekly throughout the period to discuss the foregoing and continued to meet bi-weekly after May 5th to discuss the opportunity with Montana.

XPDB entered into non-disclosure agreements with 6 of the potential 25 target businesses, including Montana, for the purposes of performing due diligence and further evaluating and analyzing these companies as potential business combination targets. The non-disclosure agreements entered into by XPDB included customary non-use provisions. Of the 6 potential target businesses with whom XPDB entered into non-disclosure agreements, the XPDB Board and XPDB’s management identified 5 potential targets during their bi-weekly meetings suitable for a business combination, including Montana: a target company that was focused on carbon capture and storage (“Company A”), a target company that was focused on manufacturing sodium ion batteries (“Company B”), a target company that was focused on providing wireless network, cloud computing and technology solutions (“Company C”) and a target company that was focused on providing environmental intelligence services (“Company D”). The due diligence of these 5 potential target businesses included, among other things, a review of information contained in online data rooms and presentations and discussions with the potential targets’ management. XPDB and its representatives evaluated and analyzed, as applicable, each potential target’s business, product pipeline, technology, historical performance, management team (and its ability to lead a public company) and competitive positioning. XPDB submitted letters of intent with Montana, Company A, Company B, Company C and Company D (the “Potential Targets”).

On January 9, 2022, Patrick C. Eilers, Chief Executive Officer of XPDB, was introduced to Stuart Porter, a member of the board of managers of Montana. Mr. Porter then introduced Mr. Eilers to Matt Jore, Chief Executive Officer of Montana. Mr. Jore responded via email and arranged for an introductory meeting to discuss Montana’s product and business.

On January 11, 2022, members of Montana’s and XPDB’s management had an introductory video teleconference in which they discussed Montana’s business and the business combination process.

Between January 11, 2022 and January 18, 2022, XPDB and Montana communicated via email to negotiate the terms of a non-disclosure agreement with respect to the sharing of confidential information, and on January 18, 2022, the parties executed the non-disclosure agreement. Later on January 18, 2022, Montana granted XPDB access to the virtual data room for the purposes of conducting business and financial due diligence with respect to Montana.

On January 28, 2022, members of Montana’s and XPDB’s management held a video teleconference in which they discussed the progress made by Montana in certain technological and product developments.

Table of Contents

Between February 1, 2022 and February 28, 2022, members of management of XPDB and Montana exchanged multiple drafts of a non-binding letter of intent (the “Initial LOI”) that was examined by the XPDB Board. XPDB and Montana executed the Initial LOI on February 28, 2022.

Between February 28, 2022 and April 8, 2022, members of Montana’s and XPDB’s management held discussions regarding Montana’s product pipeline, technology, industry dynamics, competitive positioning, historical performance, cash needs and technological progress.

On May 11 and 12 of 2022, Mr. Eilers and Paul Dabbar visited PNNL at 902 Battelle Blvd, Richland, WA, meeting Mr. Jore, Pete McGrail (Montana’s Chief Technology Officer), and JJ Jenks (Montana’s Vice President of Operations) to view the MOF technology and further assess its technology readiness level (“TRL”). The purpose of the trip was to receive an update from Montana’s management team regarding the development of its technology and the AirJoule system. XPDB’s management agreed that they would continue to monitor the development of the technology and TEP Montana, one of XPDB’s advisors that was in attendance during the May 11 and 12 visits to PNNL, decided on July 22, 2022 to make a $5 million private investment in Montana. However, because the AirJoule system was not fully developed, the XPDB management team decided that Montana was not a viable candidate for a business combination at that time.

Following the trip to PNNL, XPDB management further discussed and decided that, until a full working AirJoule benchtop prototype was viable, and its results recorded and assessed to be consistent with simulated expectations, XPDB would not consider a business combination with Montana. XPDB’s management and members of Montana then agreed to step back from the pursuit of a business combination until a later time when Montana’s products and technology had more fully matured. The parties agreed to continue to stay in touch so that XPDB could monitor Montana’s developments of its AirJoule technology.

Between December 24, 2021 and April 2022, representatives of XPDB met with representatives of Company A in person and via conference call dozens of times to discuss deal terms and due diligence questions. XPDB also submitted a non-binding letter of intent to Company A in connection with a potential business combination transaction and the parties executed the non-binding letter of intent on February 8, 2022 (the “Company A LOI”). Following the execution of the Company A LOI and further discussions between the parties, on March 29, 2022, Company A terminated discussions with XPDB due to its determination that pursuing a spinoff of its subsidiary and a subsequent business combination with XPDB had become a lower priority due to advancements in Company A’s base business.

Between December 22, 2021 and October 2022, representatives of XPDB also met with representatives of Company B in person and via conference call dozens of times to discuss deal terms and due diligence questions. XPDB also submitted a non-binding letter of intent to Company B in connection with a potential business combination transaction and the parties executed the non-binding letter of intent in July 2022 (the “Company B LOI”). XPDB and Company B and their representatives further engaged in multiple discussions between July and October 2022. In October 2022, Company B and XPDB agreed to terminate discussions due to Company B’s determination that pursuing a business combination with XPDB would be less attractive than pursuing a private financing for Company B’s business.

After discussions with Company A and Montana were terminated, XPDB began discussions with Company C in August of 2022, a company focused on advanced wireless networks, cloud computing and technology solutions. XPDB began evaluations of Company C following an introduction through Mr. Widham and conducted substantial due diligence of Company C, including review of historic and budgeted financial statements, market analysis, technical analysis, financial analysis, legal analysis and competitive benchmarking.

Representatives of XPDB met with representatives of Company C more than 11 times to discuss deal terms and due diligence questions. XPDB also submitted a non-binding letter of intent to Company C in connection with a potential business combination transaction and the parties executed the non-binding letter of intent on December 9, 2022. The shareholders of Company C determined not to proceed with a business combination with XPDB but instead decided to pursue a private financing and XPDB began to assess other opportunities.

After discussions with Company C were terminated, XPDB began discussions with Company D, a public benefit corporation focused on providing environmental intelligence, synthetic natural capital monetization and regenerative ecoculture services. XPDB and its representatives conducted substantial due diligence of Company D, including review of historic and budgeted financial statements, market analysis, financial analysis, legal analysis and competitive benchmarking.

XPDB and its representatives met with representatives of Company D more than dozens of times to discuss deal terms and due diligence questions. XPDB also submitted a non-binding letter of intent to Company D in connection with a potential business combination transaction and the parties executed the non-binding letter of intent on January 7, 2023 (the “Company D LOI”). Following the execution of the Company D LOI, XPDB and Company D proceeded to negotiate the initial drafts of the primary transaction documents based on the terms of the Company D LOI, including, a merger agreement and governance documents for the post-combination company. An initial draft of the merger agreement was shared with XPDB by Company D’s representatives. After a month of negotiations, due diligence and the exchange of initial transaction documents, the owners of Company D decided to delay a public market listing and therefore not proceed with a business combination with XPDB and XPDB began to assess other opportunities.

On March 16, 2023, Mr. Eilers visited Ronan, Montana (the headquarters of Montana) to witness the first testing of the complete AirJoule prototype, which included the MOF coated contactors he had seen at PNNL on May 11, 2022. Mr. Eilers informed the rest of XPDB management of the successful tests of the AirJoule prototype by Montana that demonstrated significant progress in the maturity of Montana’s business, products and technology. Mr. Eilers contacted Mr. Jore and Mr. Jore responded via email and arranged for a re-introductory video teleconference to discuss the evolution of Montana’s technology, products and business since XPDB last engaged with Montana regarding a potential business combination in the spring of 2022.

On March 23, 2023, members of Montana’s and XPDB’s management had a re-introductory video teleconference in which they discussed Montana’s business and the business combination process. Importantly, Montana had executed a global supply relationship with BASF to supply the MOF on economic terms that could enable its balance of materials cost to economically scale, assisting market adoption and penetration.

Between March 23, 2023 and June 5, 2023, representatives of XPDB and certain third-party consultants, who were engaged by XPDB to assist XPDB in its business and financial due diligence, conducted business and financial due diligence with respect to Montana’s business, including with respect to its product pipeline, technology, industry dynamics, competitive positioning and historical performance, and XPDB’s management, representatives and advisors reviewed information available in the virtual data room, asked follow-up questions of, and received written responses from, Montana’s management and participated in due diligence calls with Montana’s management and advisors. Importantly, this diligence included a technical assessment conducted by an independent national laboratory to assess the TRL of AirJoule, which concluded that the AirJoule was at a TRL of 6 and expected to reach a TRL of 7 or greater within the next 6 months. As a result of its due diligence, including the review of the technical assessment, XPDB’s management determined that Montana had made satisfactory progress in advancing the TRL of AirJoule.

In addition, since March 2023, the XPDB Board met regularly with members of XPDB’s management and its representatives in attendance. XPDB’s management provided progress updates on discussions with Montana. Mr. Eilers led the discussions, and the XPDB Board discussed, among other things, the potential target sourcing process, the SPAC market, and a detailed potential target pipeline (including Montana).

Between April 8 and May 8, 2023, members of management of XPDB and Montana exchanged multiple iterations of a new non-binding letter of intent (the “LOI”). On May 8, 2023, XPDB and Montana executed the LOI, which contemplated a $500 million pro forma enterprise value for Montana and the opportunity for Montana Equityholders to earn additional equity consideration upon the achievement of certain milestones related to production capacity and anticipated Annualized EBITDA of the Post-Combination Company following the Closing. The LOI stipulated that, subject to tax diligence and structuring analysis, (i) XPDB would remain a publicly traded company and Montana shares would be exchanged for shares in XPDB based on a $10.00 share value, (ii) there would be a six (6) month lock-up period for Sponsor, investors (including investors in the contemplated Capital Raise), management, and any shareholder of greater than 5%, (iii) Montana would undertake a Capital Raise in the amount of $100 million during the interim period, (iv) the number of directors on the Post-Combination Company Board would be determined through subsequent discussions, with two (2) being appointed by XPDB, (v) the representations and warranties in the Merger Agreement would not survive, (vi) there would be mutual exclusivity between XPDB and Montana and (vii) there would also be customary closing conditions and registration rights.

Between late April 2023 and early June 2023, representatives from Barclays, XPDB and Montana participated in several calls (and took part in a site visit of Montana’s facilities) to conduct due diligence on Montana’s business and discuss the proposed transaction, including, but not limited to, the valuation framework and the content of the management presentation.

Beginning on May 2, 2023, XPDB’s management and Montana’s management met together and with their legal advisors on regularly scheduled calls to discuss Montana’s business and deal progress.

On May 9, 2023, representatives from XPDB, Montana, Latham & Watkins LLP (counsel to Montana (“Latham”)) and Kirkland & Ellis LLP (counsel to XPDB (“Kirkland”)) had a call to discuss the deal process and steps required to complete the proposed transaction.

Throughout the month of May 2023, XPDB and its advisors issued due diligence requests to Montana, conducted operational, legal, financial, accounting, tax, information technology, and environmental due diligence, and participated in various discussions with representatives of Montana. In particular, during May and June of 2023, members of XPDB’s management and the XPDB Board visited Montana’s facilities and conducted site diligence. Additionally, on May 30, 2023, XPDB’s management and its advisors participated in a diligence call with Montana’s management, wherein the parties discussed specific diligence questions relating to Montana’s business and legal organization, labor and employment practices, employee benefits and executive compensation matters, real estate portfolio, environmental matters, intellectual property matters, and matters specific to the industry in which Montana operates.

On May 16, 2023, representatives from XPDB, Montana, Latham and Kirkland had a call to discuss the deal process, Merger Agreement ancillary documents and steps required to complete the proposed transaction. On May 23, 2023, representatives from XPDB, Montana, Latham and Kirkland had another call to further discuss the deal process, Merger Agreement ancillary documents and steps required to complete the proposed transaction.

On May 24, 2023, Kirkland distributed to Montana and Latham an initial draft of the Merger Agreement and other agreements necessary to consummate the proposed business combination. The initial draft of the Merger Agreement contemplated, among other items: (i) the Merger, (ii) no survival of the representations, warranties and covenants, (iii) listing of the Post-Combination Company’s common stock issued to Montana Equityholders as Merger Consideration on a national securities exchange following completion of the Merger, (iv) additional equity consideration upon the achievement of certain milestones related to production capacity and anticipated Annualized EBITDA of the Post-Combination Company following the Closing, (v) certain covenants regarding claims against XPDB’s Trust Account, (vi) regulatory efforts covenants requiring XPDB and Montana to use commercially reasonable efforts in order to obtain regulatory clearance, (vii) the entry into certain ancillary agreements concurrently with the execution of the Merger Agreement, (viii) representations, warranties and covenants customary for transactions of this type and (ix) a proposed Capital Raise in the amount of $100 million (the Capital Raise was later reduced to $85 million in subsequent drafts of the Merger Agreement).

On May 28, 2023, Kirkland and Latham conducted a call regarding a Merger Agreement issues list.

On May 30, 2023, Montana, XPDB, Barclays (along with Barclays’ legal counsel, Vinson & Elkins LLP) and their representatives held three separate due diligence sessions via video teleconference and Montana provided XPDB’s management with an overview of its business.

On May 30, 2023, members of XPDB’s and Montana’s management and their representatives, including Latham and Kirkland, had a call to discuss the deal process, the Merger Agreement, ancillary transaction documents and steps required to complete the proposed business combination. Later on that same day, Kirkland distributed to Latham the initial draft of the Sponsor Support Agreement and the Lock-Up Agreement, which provided, among other things, that the Sponsor agree to vote any Sponsor Securities held by it in favor of the transactions contemplated by the Merger Agreement.

On May 31, 2023, Latham returned a revised draft of the Merger Agreement that proposed various revisions to the structure of the Business Combination, including revisions to the Merger Consideration, treatment of equity interests, the earnout provisions and the representations and warranties of both Montana and XPDB. Latham proposed changes to the interim operating covenants and various tax matters. Latham also distributed initial drafts of the Proposed Charter and the Amended and Restated Bylaws. Later, on May 31, 2023, Latham distributed to Kirkland an initial draft of Montana’s disclosure letter.

On June 1, 2021, Latham distributed to Kirkland an initial draft of the form of Registration Rights Agreement.

On June 2, 2023, Latham sent Kirkland a revised draft of the Lock-Up Agreement.

Later, on June 2, 2023, a virtual meeting of the XPDB Board was held, with XPDB’s management and representatives from Kirkland in attendance. Kirkland provided the XPDB Board with an overview of their fiduciary duties under Delaware law, a summary of the then-current drafts of the Merger Agreement and ancillary documents and a summary of the diligence conducted to date. The XPDB Board discussed and considered various matters related to the proposed transaction and diligence, the Merger Agreement, ancillary documents, the deal process and valuation, including reviewing the financial analysis prepared by the XPDB management team throughout May 2023.

On June 3, 2023, after having reviewed each of Latham’s proposed changes and discussed with the XPDB management team, Kirkland sent Latham a revised draft of the Merger Agreement. The revised draft proposed various revisions to the treatment of Merger Consideration, Montana’s equity interests, the earnout provisions, revisions to the representations and warranties and the interim operating covenants. Kirkland also proposed revisions to various tax matters and closing conditions.

Later that day, Latham and Kirkland also exchanged drafts of the Sponsor Support Agreement, the Lock-Up Agreement, the Registration Rights Agreement and the Proposed Charter and Amended and Restated Bylaws; and Kirkland distributed to Latham an initial draft of XPDB’s disclosure letter along with initial comments to Montana’s disclosure letter.

On June 4, 2023, Kirkland distributed a further revised draft of the Merger Agreement with additional revisions to the earnout provisions. Later that day, Latham distributed a revised draft of XPDB’s disclosure letter as well as a further revised draft of Montana’s disclosure letter.

On June 4, 2023, representatives from XPDB, Montana, Latham and Kirkland held a call via teleconference to discuss remaining open points of the Merger Agreement and ancillary documents.

During the evening of June 4, 2023, and the early morning of June 5, 2023, Latham and Kirkland, together with Montana and XPDB, further negotiated and finalized various aspects of the Merger Agreement, ancillary agreements and disclosure letters including, among other items, further revisions to the treatment of the Merger Consideration, equity interests, earnout and certain covenants related to the Capital Raise.

On June 5, 2023, Kirkland and Latham exchanged the final drafts of the Merger Agreement and ancillary transaction documents. XPDB and Montana agreed that all documents were in final form.

On the morning of June 5, 2023, a virtual meeting of the XPDB Board was held with representatives of Kirkland and XPDB’s management in attendance. Prior to the meeting, the XPDB Board was provided with the substantially final form of the Merger Agreement, Sponsor Support Agreement and the related ancillary agreements and, at the meeting, Kirkland provided the XPDB Board with an overview of the key updates to the Merger Agreement and the related ancillary agreements made since the June 2nd XPDB Board meeting. The XPDB Board then discussed the merits of the proposed transaction with Montana. Following such discussion, the XPDB Board unanimously adopted and approved, among others, resolutions (a) determining that it is in the best interests of XPDB and its stockholders for XPDB to negotiate, execute and deliver the Merger Agreement, the ancillary agreements and the Business Combination; (b) approving and declaring advisable the Merger Agreement and approving the ancillary agreements; and (c) recommending that the XPDB stockholders vote in favor of the Proposals set forth in this proxy statement/prospectus.

Also on the morning of June 5, 2023, the parties finalized and executed (as applicable) the Merger Agreement, the disclosure letters, the Sponsor Support Agreement and the forms of the other ancillary agreements included as exhibits to the Merger Agreement.

Prior to the open of trading on the Nasdaq on the morning of June 5, 2023, XPDB and Montana issued a joint press release announcing the Business Combination.

Recommendation of the XPDB Board and Reasons for the Business Combination

The XPDB Board, in evaluating the Business Combination, consulted with XPDB’s management, legal and financial advisors, and technical consultants. In reaching its unanimous resolution (i) determining that the Merger Agreement and the transactions contemplated thereby, including the Business Combination and the issuance of shares of Class A Common Stock in connection therewith, are advisable and in the best interests of XPDB and its stockholders and (ii) recommending that the XPDB stockholders adopt the Merger Agreement and approve the Business Combination, the XPDB Board considered a range of factors, including, but not limited to, the factors

161

Table of Contents

discussed below. In light of the large number and wide variety of factors considered in connection with its evaluation of the Business Combination, the XPDB Board did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors that it considered in reaching its determination and supporting its decision. The XPDB Board viewed its decision as being based on all of the information available and the factors presented to and considered by it. In addition, individual directors may have given different weight to different factors.

This explanation of XPDB’s reasons for the Business Combination and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under “Forward-Looking Statements.”

Before reaching its decision, the XPDB Board reviewed the results of XPDB management’s due diligence, which included:

• research on industry trends, projected growth and other industry factors, including the TAM for the AirJoule technology;

• extensive meetings and calls with Montana’s management team and representatives regarding Montana’s business, the manufacture and commercialization of the AirJoule units, major suppliers and partners, financial prospects and competitive positioning, among other customary due diligence matters;

• consultation with XPDB’s legal and financial advisors, and technical consultants;

• a third-party national laboratory report, commissioned by XPDB, regarding the validity and commercial viability of the AirJoule technology;

• review of Montana’s material contracts and certain other legal, intellectual property and commercial diligence;

• financial, accounting and tax diligence;

• research on comparable public companies; and

• review of Montana’s potential manufacturing MOF coating line economics, which illustrate potential Annualized EBITDA of $300 million for three lines based on Montana’s sole ownership of production and potential Annualized EBITDA of $150 million for three lines based on Montana’s ownership through a joint venture.

In approving the Business Combination, the XPDB Board determined not to obtain a fairness opinion. The officers and directors of XPDB have substantial experience in evaluating the operating and financial merits of companies from a wide range of industries and concluded that their experience and background, together with the experience and sector expertise of XPDB’s advisors, enabled them to make the necessary analyses and determinations regarding the Business Combination. In addition, XPDB’s officers and directors and XPDB’s advisors have substantial experience with mergers and acquisitions. Although the XPDB Board did not seek a third-party valuation, and did not receive any valuation or opinion from any third party in connection with the Business Combination, the XPDB Board relied on the following sources: (i) due diligence on Montana’s operations, (ii) research reports and data related to the HVAC and water industries and (iii) XPDB management’s collective experience in conducting valuations of businesses. The XPDB Board concluded that the $500 million pro forma enterprise value is fair and reasonable, given Montana’s growth prospects and the need for global comfort cooling and water that drive the large and growing markets for HVAC and atmospheric renewable energy and water harvesting technology, Montana’s TAM relating to the opportunity to deploy AirJoule technology to provide energy, cost-efficient and sustainable dehumidification, evaporative cooling and atmospheric water generation, the XPDB Board’s review and analysis of Montana and of comparable public companies as described below, and other compelling aspects of the transaction.

The XPDB Board considered a number of factors pertaining to the Business Combination, which the XPDB Board concluded generally supported its decision to authorize and approve XPDB’s entry into the Merger Agreement and the transactions contemplated thereby. Below is a list of the material factors that the XPDB Board considered:

• Transformative Technology with Potential to Provide Energy and Cost-Efficient and Sustainable Dehumidification, Evaporative Cooling and Atmospheric Water Generation. The AirJoule is a new atmospheric renewable energy and water harvesting technology that has the capability to provide energy,

162

Table of Contents

cost-efficient and sustainable dehumidification, evaporative cooling and atmospheric water generation. The XPDB Board believed this technology is transformative based on a technical report performed by an independent third-party national laboratory, which the XPDB Board viewed as validation of the AirJoule’s capabilities and advantages over existing conventional vapor compression dehumidification systems and desiccant dehumidifiers (including that AirJoule’s moisture removal efficiency is expected to be approximately 4 times and 11 times more efficient than conventional vapor compression dehumidification systems and desiccant dehumidifiers, respectively) and AirJoule’s ability to provide cost-efficient and sustainable dehumidification, evaporative cooling and atmospheric water generation.

• Market Opportunity to Address Areas of High Unmet Comfort Cooling and Water Needs. The XPDB Board considered the potential for the AirJoule to address the world’s expanding needs for comfort cooling and water across a range of industries, including HVAC and other industries with high water use. The XPDB Board believed that the TAM related to the opportunity to deploy AirJoule technology to provide energy and cost-efficient and sustainable dehumidification, evaporative cooling and atmospheric water generation is large and attractive.

• Commercial Validation of the AirJoule Technology. The AirJoule technology has been validated as a potentially market disruptive technology with potential global impact on reducing a material amount of energy consumption associated with dehumidification, cooling and water harvesting by an independent third-party national laboratory, who reviewed the technology at the request of XPDB and concluded that the AirJoule was at a TRL of 6 and expected to reach a TRL of 7 or greater within the next 6 months, and commercially validated by large industrial public company conglomerates who are current and potential partners of Montana, including BASF and CATL. BASF has successfully produced Montana’s proprietary MOF for AirJoule prototypes and is now scaling for mass production. The XPDB Board believed that the potential demand for the AirJoule is large and will continue to grow as the AirJoule is commercialized.

• Attractive Entry Valuation. The financial analysis conducted by XPDB’s management and reviewed by the XPDB Board supported the valuation of Montana. The XPDB Board reviewed Montana’s potential manufacturing MOF coating line economics, including illustrative sales prices and production costs, which illustrate potential Annualized EBITDA of $300 million for three lines based on Montana’s sole ownership of production and potential Annualized EBITDA of $150 million for three lines based on Montana’s ownership through its joint venture with CATL US. See the section entitled “Information About Montana — Our Partners” for a description of the material terms of Montana’s A&R Joint Venture Agreement with CAMT and CATL US. Although Montana does not have contractual revenue arrangements in place, the XPDB Board believed the illustrative potential Annualized EBITDA was reasonable because the assumptions in sales price and expected production costs of MOF coated contactors underlying the Annualized EBITDA were consistent with components in existing conventional cooling and dehumidification technologies, and the other key components of the AirJoule are used in mature manufacturing processes with costs that are generally known in the HVAC and water harvesting industries. Furthermore, achieving the illustrative potential Annualized EBITDA would require capturing only a small fraction of the estimated $455 billion combined TAM of the HVAC and atmospheric water harvesting sectors, which the XPDB Board further believed is reasonable due to the advantages of the AirJoule technology compared to conventional technologies as discussed above. Finally, the XPDB Board viewed the technical report performed by an independent third-party national laboratory as validation of the commercial feasibility of the potential manufacturing MOF coating line economics, including the underlying assumed sales price and expected production costs. XPDB’s management prepared its valuation of Montana, including a sensitivity analysis with various multiples and numbers of production lines, using the potential Annualized EBITDA assuming full construction of manufacturing lines, and did not prepare an analysis of expected revenues or EBITDA on a year-by-year basis. To account for the risks and time inherent in the commercialization and execution of a new technology, XPDB’s management assumed a ten (10) times multiple, which they believed was reasonable as it was lower than the EBITDA multiple observed among comparable companies (see below the discussion on the illustrative comparable company analysis) and applied such multiple to Montana’s potential annualized three manufacturing line joint venture EBITDA of $150 million, resulting in an implied fully distributed enterprise value of $1.5 billion. The $500 million pro forma enterprise value for Montana implied a further 67% discount. The XPDB Board believed the combined lower multiple and implied 67% discount appropriately accounted for the risks and time to commercialize and execute on a new technology, and that the $500 million pro forma

163

enterprise value is favorable to investors seeking long-term return potential for an early-stage business with validated technology. See below for a discussion of various uncertainties and risks considered by the XPDB Board.

• Illustrative Comparable Company Analysis. XPDB’s management also reviewed information of comparable publicly traded companies, based on the experience and professional judgment of XPDB’s management. In particular, XPDB selected publicly traded companies in two markets, HVAC and water production and processing, due to the relationship of Montana’s technology to the HVAC and water harvesting industries. Although the selected comparable companies are not directly comparable because they utilize mature technologies, whereas Montana’s technology touches both industries and is a new technology, XPDB’s management believed a comparison to these companies to be useful, based on their analysis of growth rates, profitability, size, geographic region and market potential across the comparable companies in these markets. The ten (10) times multiple was a discount to the observed average HVAC and water multiples of peer companies.

The average multiple of projected EBITDA for the calendar year 2024 for the HVAC industry as of June 2, 2023 was 12.5 times and the constituents included were: Carrier; Daikin; Johnson Controls; Lennox; Munters; and Trane.

The average multiple of projected EBITDA for the calendar year 2024 for the water industry as of June 2, 2023 was 19.0 times and the constituents included were: Ecolab; Evoqua Water Technologies; Watts Water Technologies, Inc.; and Xylem.

• Experienced and Proven Management Team. Montana has a strong management team with significant operating experience. The senior management of Montana (including Matt Jore, Chief Executive Officer of Montana) intends to remain with Montana in the capacity of officers and/or directors, providing helpful continuity in advancing Montana’s strategic and growth goals. Montana’s senior management team also includes technical expertise applicable to its business, including senior managers with experience at PNNL where they led the development of the original technology underlying the AirJoule technology which PNNL patented;

• Stockholder Liquidity. Pursuant to the Merger Agreement, the Class A Common Stock issued as Merger Consideration will be listed on the Nasdaq, a major U.S. stock exchange, which the XPDB Board believed has the potential to offer stockholders enhanced liquidity;

• Lock-Up. Certain Montana Equityholders will be subject to a six-month lock-up with respect to any shares of Class A Common Stock, Class B Common Stock, or any shares of common stock issuable upon the exercise of options or warrants to purchase shares of common stock received by them pursuant to the terms of the Merger Agreement, subject to certain customary exceptions, which lock-up will provide important stability to the leadership and governance of Montana;

• Other Alternatives. The XPDB Board has determined that the proposed Business Combination represents the best potential business combination for XPDB based upon the process utilized to evaluate and assess other potential acquisition targets. The XPDB Board has also determined that such process has not presented a better alternative; and

• Negotiated Transaction. The XPDB Board has determined that the financial and other terms of the Merger Agreement are reasonable and were the product of arm’s-length negotiations between XPDB and Montana.

The XPDB Board also considered various uncertainties and risks and other potentially negative factors concerning the Business Combination. Below is a list of the material uncertainties, risks and other potentially negative factors that the XPDB Board considered:

• Macroeconomic Risks. Macroeconomic uncertainty, including the potential impact of the COVID-19 pandemic, the invasion of Ukraine by Russia and resulting sanctions, and other events (such as terrorist attacks, geopolitical unrest, natural disasters or a significant outbreak of other infectious diseases) and the effects these could have on the Post-Combination Company’s revenues;

164

Table of Contents

• Business Plan May Not Be Achieved. The risk that Montana may not be able to execute on its business plan to commercialize AirJoule units consistent with the manufacturing MOF coating line economics provided to XPDB or at all due to higher than expected costs, lower than expected growth, a smaller than expected TAM, unexpected competition or slower than expected development of strategic partnerships;

• Early Stage Company and Limited Operating History. The fact that Montana is an early stage, pre-revenue company with a history of losses and a limited operating history;

• Technology Risk. The risk that patent applications may not result in issued patents, and Montana’s issued patents may not provide adequate protection to its intellectual property, which may have a material adverse effect on Montana’s ability to prevent others from commercially exploiting products similar to Montana’s and Montana’s failure to protect its intellectual property and technology could have a material adverse impact on its competitive position and business;

• Regulatory Risk. The risk that Montana may require numerous permits, licenses and other approvals from various governmental agencies, and the failure to obtain or maintain any of them, or delays in obtaining them, could have a material adverse effect on Montana’s business;

• Redemption Risk. The potential for a significant number of XPDB stockholders electing pursuant to the Existing Charter to redeem their shares prior to the consummation of the Business Combination, which would potentially make the Business Combination more difficult or impossible to complete;

• Stockholder Vote. The risk that XPDB’s stockholders may fail to provide the applicable votes necessary to effect the Business Combination;

• Closing Conditions. The fact that the completion of the Business Combination is conditioned on the satisfaction of certain closing conditions that are not within XPDB’s control;

• Litigation. The possibility of (i) litigation challenging the Business Combination or (ii) an adverse judgment granting permanent injunctive relief that could indefinitely delay consummation of the Business Combination;

• Listing Risks. The challenges associated with preparing Montana, a private entity, for the applicable disclosure and listing requirements to which the Post-Combination Company will be subject as a publicly traded company on the Nasdaq;

• Benefits May Not Be Achieved. The risks that the potential benefits of the Business Combination may not be fully achieved or may not be achieved within the expected timeframe;

• Liquidation of XPDB. The risks and costs to XPDB if the Business Combination is not completed, including the risk of diverting management focus and resources from other business combination opportunities, which could result in XPDB being unable to effect a business combination by December 14, 2023 or such further extended date as determined by the XPDB Board in accordance with the Existing Charter;

• No Third-Party Valuation. XPDB’s decision not to obtain a third-party valuation or fairness opinion in connection with the Business Combination;

• XPDB Stockholders Receiving a Minority Position in Montana. The risks associated with the minority position in the Post-Combination Company that XPDB stockholders will hold following consummation of the Business Combination; and

• Fees and Expenses. The fees and expenses associated with completing the Business Combination.

In addition to considering the factors described above, the XPDB Board also considered other factors, including, without limitation:

• Interests of Certain Persons. Some officers and directors of XPDB may have interests in the Business Combination (see “Business Combination — Interests of the Sponsor and XPDB’s Directors and Executive Officers in the Business Combination”).

• Other Risk Factors. Various other risk factors associated with the business of Montana, as described in the section entitled “Risk Factors” appearing elsewhere in this proxy statement/prospectus.

165

Table of Contents

The XPDB Board concluded that the potential benefits that it expects XPDB and its stockholders to achieve as a result of the Business Combination outweigh the potentially negative and other factors associated with the Business Combination. Accordingly, the XPDB Board, acting pursuant to the authority delegated to it by the full XPDB Board to approve the Business Combination, unanimously determined that the Business Combination is advisable and in the best interests of XPDB and its stockholders. The Annualized EBITDA, pro forma enterprise value and underlying assumptions described herein represent management’s current view as of October 2, 2023, the date of filing hereof.

Satisfaction of 80% Test

The Nasdaq rules require that XPDB’s initial business combination must occur 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 (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in the Trust Account) at the time of XPDB’s signing a definitive agreement in connection with its initial business combination. As of June 5, 2023, the date of the execution of the Merger Agreement, the value of the net assets held in the Trust Account was approximately $292.8 million (excluding approximately $6 million of the Deferred Discount held in the Trust Account) and 80% thereof represents approximately $234.32 million. In reaching its conclusion that the Business Combination meets the 80% asset test, the XPDB Board used as a fair market value the enterprise value of approximately $500 million, which was implied based on the terms of the transactions agreed to by the parties in negotiating the Merger Agreement.

In determining whether the enterprise value described above represents the fair market value of Montana, the XPDB Board considered all of the factors described in this section and the section of this proxy statement/prospectus entitled “The Merger Agreement” and the fact that the purchase price for Montana was the result of an arm’s-length negotiation. As a result, the XPDB Board concluded that the fair market value of the business acquired was significantly in excess of 80% of the net assets held in the Trust Account (net of amounts disbursed to management for working capital purposes and excluding the amount of the Deferred Discount held in the Trust Account).

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

In considering the recommendation of the XPDB Board to vote in favor of approval of the Proposals, XPDB Public Stockholders should keep in mind that the Sponsor and XPDB’s directors and officers have interests in such Proposals that are different from or in addition to (and which may conflict with) those of XPDB Public Stockholders. XPDB Public Stockholders should take these interests into account in deciding whether to approve the proposals presented at the Special Meeting, including the Business Combination Proposal. These interests include, among other things:

• If the Business Combination with Montana or another business combination is not consummated within the Completion Window, XPDB will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and the XPDB Board, dissolving and liquidating. In such event, the 7,187,500 Founder Shares purchased by the Sponsor for an aggregate purchase price of $25,000, or approximately $0.004 per share, and held by the Initial Stockholders would be worthless because the Initial Stockholders are not entitled to participate in any redemption or distribution with respect to such shares. Such shares had an aggregate market value of $76,187,500 based upon the closing price of $10.60 per share of XPDB Class A Common Stock on the Nasdaq on September 29, 2023, the most recent practicable date prior to the date of this proxy statement/prospectus. Certain Founder Shares are subject to certain time and performance-based vesting provisions as described under “Other Agreements — Sponsor Support Agreement.”

• The Sponsor purchased an aggregate of 8,900,000 Private Placement Warrants from XPDB for an aggregate purchase price of $8,900,000 (or $1.00 per warrant). Such Private Placement Warrants had an aggregate market value of $890,000 based upon the closing price of $0.10 per XPDB public warrant on the Nasdaq on September 29, 2023, the most recent practicable date prior to the date of this proxy statement/prospectus. The Private Placement Warrants will become worthless if XPDB does not consummate a business combination within the Completion Window.

166

Table of Contents

• The Sponsor has agreed that it will be liable to us if and to the extent any claims by a vendor for services rendered or products sold to us, or a prospective target business, with which we have discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.10 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes. If XPDB consummates the Business Combination, on the other hand, XPDB will be liable for all such claims.

• XPDB’s directors and officers, and their affiliates, are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on XPDB’s behalf, such as identifying and investigating possible business targets and business combinations. However, if XPDB fails to consummate a business combination within the Completion Window, they will not have any claim against the Trust Account for reimbursement. Accordingly, XPDB may not be able to reimburse these expenses if the Business Combination or another business combination is not consummated within the Completion Window.

• The Sponsor, officers and directors have agreed not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (i) six months after the completion of the Business Combination and (ii) the date following the completion of the Business Combination on which we complete a liquidation, merger, capital stock exchange or other similar transaction that results in all of our stockholders having the right to exchange their common stock for cash, securities or other property, subject to certain exceptions.

• Subject to certain limited exceptions, the Private Placement Warrants will not be transferable until 30 days following the completion of the Business Combination.

• No compensation of any kind, including finder’s and consulting fees, is paid to our Sponsor, officers and directors, or any of their respective affiliates, for services rendered prior to or in connection with the completion of an initial business combination, except for reimbursement for out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations, $20,000 per month for office space, secretarial and administrative services (these amounts are accruing and have yet to be paid), advisory fees and consulting fees in an aggregate amount of up to $3,000,000 that will be paid to XMS Capital and TEP in connection with the Business Combination. Such arrangement will terminate upon the consummation of the Business Combination. From the date of the XPDB IPO until the date of the Merger Agreement, there have been no reimbursable out-of-pocket expenses incurred by the Sponsor in connection with the Business Combination other than certain expenses in connection with conducting due diligence on Montana.

• The continued indemnification of current directors and officers and the continuation of directors’ and officers’ liability insurance.

• Due to the differential in the purchase price that the Sponsor and its affiliates paid for the Founder Shares and Private Placement Warrants as compared to the price of the Public Shares sold in the XPDB IPO and the substantial number of XPDB Class A Common Stock our Sponsor will receive upon conversion of the Founder Shares in connection with the Business Combination and exercise of the Private Placement Warrants, our Sponsor and its affiliates may earn a positive rate of return on their investment even if other XPDB Public Stockholders experience a negative rate of return in the Post-Combination Company, and they may therefore be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to XPDB stockholders rather than liquidate.

• One of our directors, Patrick C. Eilers, is a majority investor in TEP Montana, which owns 77,095 Montana Class B Common Units, or 4.9% of Montana’s outstanding units. TEP Montana paid approximately $4,452,825 for such units. Assuming that there is no Capital Raise or further dilution to the Montana Common Units, TEP Montana will receive approximately 1,857,301 shares of Class A Common Stock at the Closing, which, at a price of $10.00 per share, will have an aggregate value of $18,573,010 (of these shares, 1,667,256 shares having an aggregate value of $16,672,560 would be indirectly owned by Mr. Eilers). Mr. Eilers is an advisor to the Montana board of managers. Additionally, Mr. Eilers is expected to be a member of the Post-Combination Company Board following the Closing.

(1) This presentation assumes a value of $10.00 per share, the deemed value of the Class A Common Stock in the Business Combination.

(2) This presentation assumes a market value of $890,000 based upon the closing price of $0.10 per XPDB public warrant on the Nasdaq on September 29, 2023, the most recent practicable date prior to the date of this proxy statement/prospectus.

(3) The Sponsor is the record holder of such shares. The Sponsor is controlled by its managing members, Messrs. Brombach and Eilers. Accordingly, all of the shares held by the Sponsor may be deemed to be beneficially held by Messrs. Brombach and Eilers. Each such person disclaims beneficial ownership of these securities, except to the extent, if any, of his pecuniary interest therein.

(4) This presentation assumes each Anchor Investor purchases only 25% of the maximum number of shares to which they are entitled pursuant to the subscription agreement to which each is a party.

In the aggregate, the Sponsor paid an aggregate of $8,925,000 for the Founder Shares and Private Placement Warrants, which are valued at approximately $72,765,000, and which would become worthless if XPDB does not consummate the Business Combination within the Completion Window. Specifically, approximately $69,179,680 of such amount is the value of the Sponsor and its affiliates’ Founder Shares (assuming (i) a value of $10.00 per share, the deemed value of the Class A Common Stock in the Business Combination, and (ii) on the date of the Business Combination, the Anchor Investors purchased from XPDB an aggregate of approximately 269,532 Founder Shares for an aggregate purchase price of approximately $1,078.13, or approximately $0.004 per share), and approximately $890,000 of such amount is the value of the Sponsor’s Private Placement Warrants (based on the market price of $0.10 per XPDB public warrant on the Nasdaq on September 29, 2023). There are no fees contingent upon a business combination payable to the Sponsor’s affiliates upon consummation of the Business Combination nor out-of-pocket expenses reimbursable to our directors and officers or affiliates except for reimbursement for out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations advisory fees and consulting fees that will be paid to XMS Capital and TEP in connection with the Business Combination. The foregoing interests present a risk that the Sponsor and its affiliates will benefit from the completion of a business combination, including in a manner that may not be aligned with XPDB Public Stockholders. As such, the Sponsor may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to stockholders rather than liquidate.

REGULATORY APPROVALS REQUIRED FOR THE BUSINESS COMBINATION

Completion of the Business Combination is subject to approval under the HSR Act. Each of Montana and XPDB have agreed to use their respective commercially reasonable efforts to take, or cause to be taken, all action, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws to consummate and make effective the Business Combination as promptly as practicable and to obtain all licenses, permits, clearances, consents, approvals, authorizations, qualifications and orders necessary to be obtained from any third party or any governmental entity in order to consummate the Business Combination.

HSR Act

Under the HSR Act, and related rules, the transactions may not be completed until notifications have been filed with and certain information has been furnished to the Antitrust Division of the Department of Justice (the “Antitrust Division”) and the Federal Trade Commission (the “FTC”) and all statutory waiting period requirements have been satisfied. XPDB and Montana filed Notification and Report Forms with the Antitrust Division and the FTC on June 20, 2023, and the 30-day waiting period expired at 11:59 p.m., New York City time, on July 20, 2023.

At any time before or after the completion of the Business Combination, the Antitrust Division, the FTC or foreign antitrust authorities could take action under the U.S. or foreign antitrust laws, including seeking to prevent the Business Combination, to rescind the Business Combination or to clear the Business Combination subject to the divestiture of assets of XPDB or Montana or subject to other remedies. In addition, U.S. state attorneys general could take action under the antitrust laws as they deem necessary or desirable in the public interest including without limitation seeking to enjoin the completion of the transactions or permitting completion subject to the divestiture of assets of XPDB or Montana or other remedies. Private parties may also seek to take legal action under the antitrust laws under some circumstances. There can be no assurance that a challenge to the transactions on antitrust grounds will not be made or, if such challenge is made, that it would not be successful.

There can be no assurances that there will be no litigation challenging such approvals.

THE MERGER AGREEMENT

This section describes the material terms of the Merger Agreement. The description in this section and elsewhere in this proxy statement/prospectus is qualified in its entirety by reference to the complete text of the Merger Agreement, dated as of June 5, 2023, a copy of which is attached as Annex A to this proxy statement/prospectus. This summary does not purport to be complete and may not contain all of the information about the Merger Agreement that is important to you. You are encouraged to read the Merger Agreement carefully and in its entirety. This section is not intended to provide you with any factual information about XPDB or Montana. Such information can be found elsewhere in this proxy statement/prospectus.

The Merger Agreement summary below is included in this proxy statement/prospectus only to provide you with information regarding the terms and conditions of the Merger Agreement and not to provide any other factual information regarding XPDB, Montana or their respective businesses. Accordingly, the representations and warranties and other provisions of the Merger Agreement should not be read alone, but instead should be read only in conjunction with the information provided elsewhere in this proxy statement/prospectus.

Structure of the Business Combination

On June 5, 2023, XPDB entered into the Merger Agreement with Montana and Merger Sub, pursuant to which, among other things and subject to the terms and conditions contained in the Merger Agreement, Merger Sub will merge with and into Montana, with Montana surviving the Merger as a wholly owned subsidiary of XPDB.

172

Table of Contents

Earnout Shares

The Eligible Equityholders will also have the opportunity to receive additional equity consideration (in each case, in accordance with their respective pro rata share) in the form of Earnout Shares only upon full completion of construction and operational viability (including all permitting, regulatory approvals and necessary or useful inspections) of new production capacity of Montana’s key components or assemblies based solely on demand from bona fide customer commitments evidenced by binding contracts (or in the sole discretion of the independent members of the Post-Combination Company Board, a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known price or pricing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA of more than $150,000,000, which shall be determined by a majority of the independent members of the Post-Combination Company Board in their sole discretion, equal to (i) the ratio of (x) (1) the Expected Annualized EBITDA less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000.

The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing. A majority of the independent members of the Post-Combination Company Board then serving will have sole discretion in determining, among other things, the achievement of the applicable milestones, the calculations of payments of Earnout Shares to the applicable Montana Equityholders, the dates on which construction and operational viability of new production capacity is deemed completed and whether to consent to a transfer of the applicable Montana Equityholder’s right to receive Earnout Shares. Earnout Shares issuable in respect of Montana Options outstanding as of immediately prior to the effective time of the Merger may be issued to the holder of such Montana Option only if such holder continues to provide services (whether as an employee, director or individual independent contractor) to the Post-Combination Company or one of its subsidiaries through the date on which such Earnout Shares are issued, as determined by a majority of the independent members of the Post-Combination Company Board.

Material Adverse Effect

Under the Merger Agreement, certain representations and warranties of Montana, on the one hand, and the XPDB and Merger Sub, on the other hand, are qualified in whole or in part by a material adverse effect standard for purposes of determining whether a breach of such representations and warranties has occurred. Pursuant to the Merger Agreement, a “Material Adverse Effect” means any event, change, development, effect or occurrence that, individually or in the aggregate with all other events, changes, developments, effects or occurrences, has had or would reasonably be expected to have a materially adverse effect on the business, assets, liabilities, condition (financial or otherwise) or results of operations of Montana or XPDB and Merger Sub, as applicable, taken as a whole, subject in each case to certain customary exceptions.

The Company shall (x) promptly notify XPDB upon having knowledge of any material breach or default under, or termination of, any Subscription Agreement or any Capital Raise transaction document by any Subscriber or the Company and (y) prior to delivering any material written notice to any Subscriber with respect to any Subscription Agreement or any Capital Raise transaction document, deliver such notice to XPDB for its prior review and written consent (which consent shall not be unreasonably withheld, conditioned or delayed and email being sufficient). For the avoidance of doubt, the Company shall comply with all applicable securities laws in connection with the Capital Raise.

• During the period from the date of the Merger Agreement through the earlier of (x) termination of the Merger Agreement and (y) the date of Closing, Montana, XPDB and Merger Sub agree to give prompt notice to the other Party if such Party (a) receives a notice or other communication in writing from any third party alleging (i) that the consent of such third party is required in connection with the Business Combination, (ii) any non-compliance with law by Montana, XPDB or Merger Sub or its affiliates, (b) receives any notice or communication from any governmental entity in connection with the Business Combination or (c) becomes aware of the commencement or threat of action against Montana, XPDB or Merger Sub or its affiliates, or any of their respective properties or assets, or, to the knowledge of Montana, XPDB or Merger Sub, any officer, director, partner, member or manager of Montana, XPDB or Merger Sub or of its affiliates, in each case, in such person’s capacity as such, with respect to the consummation of the Business Combination.

• The XPDB Board will, in consultation with Montana, approve and adopt the Incentive Plan and the ESPP no later than the day before the date of Closing.

OTHER AGREEMENTS

Sponsor Support Agreement

In connection with the execution of the Merger Agreement and pursuant to the terms of the Sponsor Support Agreement entered into among the Sponsor, XPDB, Montana and certain other holders of XPDB Class B Common Stock, a copy of which is attached to this proxy statement/prospectus as Annex D, the Sponsor and the other holders of XPDB Class B Common Stock agreed to, among other things, (i) vote at the Special Meeting any Sponsor Securities, held of record or thereafter acquired in favor of the Proposals presented by XPDB at such meeting, (ii) be bound by certain other covenants and agreements related to the Business Combination, (iii) be bound by certain transfer restrictions with respect to the Sponsor Securities and (iv) waive certain antidilution protections with respect to the Sponsor Securities, in each case, on the terms and subject to the conditions set forth in the Sponsor Support Agreement. The quorum and voting thresholds at the Special Meeting and the Sponsor Support Agreement may make it more likely that XPDB will consummate the Business Combination. In addition, pursuant to the terms of the Sponsor Support Agreement, the Sponsor has agreed to waive its redemption rights with respect to any Sponsor Securities in connection with the completion of a Business Combination (which waiver was provided in connection with the XPDB IPO and without any separate consideration paid in connection with providing such waiver) until the earlier of (i) the completion of the Business Combination and (ii) the termination of the Merger Agreement.

The Sponsor has also agreed, pursuant to the terms of the Sponsor Support Agreement, to subject certain of the shares of XPDB Class A Common Stock held by the Sponsor following the conversion of the Founder Shares as of the Closing to certain vesting provisions. Specifically, the Sponsor Support Agreement provides that as of immediately prior to (but subject to) the Closing, 1,380,736 Subject Vesting Shares will be subject to certain time and performance-based vesting provisions described below. Pursuant to the Sponsor Support Agreement, Subject Vesting Shares will be subject to an earnout, with the Subject Vesting Shares vesting during the Vesting Period (i) simultaneously with the Performance Vesting Trigger and (ii) up to 50% of the Subject Vesting Shares (including any vested Subject Vesting Shares from the Performance Vesting Trigger) vesting on any day following the Closing when the Closing Share Price equals or exceeds $12.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) and all remaining Subject Vesting Shares vesting when the Closing Share Price equals or exceeds $14.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like).

The Sponsor Support Agreement will terminate on the earlier of (i) the date the Business Combination becomes effective and (ii) the termination of the Merger Agreement in accordance with its terms. Certain sections of the Sponsor Support Agreement related to vesting and other provisions shall survive termination. See the section entitled “Other Agreements — Sponsor Support Agreement.”

Registration Rights Agreement

The Merger Agreement contemplates that, at the Closing, the Post-Combination Company, Sponsor, HC NCBR Fund, Obsidian Master Fund, BlackRock Credit Alpha Master Fund L.P. and certain Montana Equityholders will enter into the Registration Rights Agreement, pursuant to which the Post-Combination Company will agree to register for resale, pursuant to Rule 415 under the Securities Act, certain shares of Class A Common Stock and other equity securities of the Post-Combination Company that are held by the parties thereto from time to time. Pursuant to the Registration Rights Agreement, the Post-Combination Company agreed to file a shelf registration statement registering the resale of the Class A Common Stock (including those held as of Closing or issuable upon future exercise of the Private Placement Warrants) and the Private Placement Warrants (the “Registrable Securities”) under the Registration Rights Agreement within 30 days after the execution of the Registration Rights Agreement. At any time and from time to time when an effective shelf registration is on file with the SEC, certain legacy Montana Equityholders, Sponsor and the Anchor Investors may request to sell all or any portion of their Registrable Securities in an underwritten offering so long as the total offering price is reasonably expected to exceed $25.0 million. The Post-Combination Company also agreed to provide customary “piggyback” registration rights, subject to certain requirements and customary conditions. The Registration Rights Agreement also provides that the Post-Combination Company will pay certain expenses relating to such registrations and indemnify the stockholders against certain liabilities.

Lock-Up Agreements

The Merger Agreement contemplates that, at the Closing, XPDB, Sponsor, XPDB’s independent directors and certain Montana Equityholders will each enter into Lock-Up Agreements, the form of which is attached to this proxy statement/prospectus as Annex G, pursuant to which the parties will be subject to certain restrictions on transfer with respect to the shares of common stock issued as part of the Merger Consideration beginning at the Closing and ending on the date that is six months after the completion of the Business Combination and with respect to the Private Placement Warrants, thirty calendar days after the completion of the Business Combination.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of the material U.S. federal income tax consequences of the exercise (if any) by Holders (as defined below) of their redemption rights in connection with the Business Combination. This discussion does not address any tax consequences of the exercise of redemption rights arising under the laws of any U.S. state or local or non-U.S. jurisdiction or under any laws other than those pertaining to income tax.

For purposes of this discussion, because any unit of XPDB (which consists of one Public Share and one-half of one redeemable XPDB public warrant to purchase one Public Share) is separable at the option of its holder, XPDB is treating any Public Share and one-half of one redeemable XPDB public warrant to purchase one Public Share, even though held in the form of a unit of XPDB, as separate instruments and is assuming that no unit of XPDB will be treated as an integrated instrument. Accordingly, the separation of a unit of XPDB in connection with the Business Combination is not expected to be a taxable event for U.S. federal income tax purposes. However, if the separation of a unit of XPDB is treated as a taxable event, the Holder of such unit may recognize gain or loss in an amount equal to the difference between (i) the fair market value, at the time of separation, of the underlying Public Share and one-half of one redeemable XPDB public warrant, and (ii) the Holder’s basis in the unit at the time of separation. Any such gain or loss generally would be long-term capital gain or loss if the Holder’s holding period for the unit exceeds one (1) year. Holders are urged to consult their tax advisors with respect to any Public Share held in the form of a unit of XPDB.

This discussion is based upon the Code, the regulations promulgated under the Code and court and administrative rulings and decisions, all as in effect on the date of this proxy statement/prospectus. These authorities may change, possibly retroactively, and any change could affect the accuracy of the statements and conclusions set forth in this discussion.

This discussion addresses only those Holders that hold each Public Share as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address any tax considerations for any transaction other than the exercise of redemption rights by certain Holders, and in particular, does not address any tax considerations with respect to the Founder Shares, warrants to acquire Public Shares, or any other transaction in connection with the Business Combination. Further, this discussion does not address all aspects of U.S. federal income taxation that may be relevant to you in light of your individual circumstances or that may be applicable to you if you are subject to special treatment under the U.S. federal income tax laws, including if you are:

• a bank or other financial institution;

• a tax-exempt organization;

• a government, or agency or instrumentality thereof;

• a real estate investment trust;

• an S corporation or other pass-through entity (or an investor in an S corporation or other pass-through entity);

• an insurance company;

• a regulated investment company or a mutual fund;

• a pension plan;

• a “controlled foreign corporation” or a “passive foreign investment company”;

• a corporation that accumulates earnings to avoid U.S. federal income tax;

• a dealer or broker in stocks, securities, commodities or currencies;

• a trader in securities that elects mark-to-market treatment;

• a Holder that received Public Shares through the exercise of an employee stock option, through a tax-qualified retirement plan or otherwise as compensation;

184

Table of Contents

• a U.S. Holder of Public Shares that has a functional currency other than the U.S. dollar;

• a Holder that holds Public Shares as part of a hedge, straddle, constructive sale, conversion or integrated transaction, or other similar transaction;

• a former citizen or long-term resident of the United States;

• a person who actually or constructively owns five (5) percent or more of the XPDB Common Stock by vote or value;

• an anchor investor;

• an officer or director of XPDB; or

• the Sponsor, its affiliates, or other holder of Founder Shares or Private Placement Warrants.

For purposes of this discussion, the term “U.S. Holder” means a beneficial owner of Public Shares that is for U.S. federal income tax purposes (1) an individual who is a citizen or resident of the United States, (2) a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of such trust or (b) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes or (4) an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source. A “Non-U.S. Holder” means a beneficial owner of Public Shares (other than a partnership or other entity or arrangement classified as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder. “Holders” means, collectively, U.S. Holders and Non-U.S. Holders.

If an entity or an arrangement treated as a partnership for U.S. federal income tax purposes holds Public Shares, the U.S. federal income tax consequences of a redemption of Public Shares to a partner in such partnership (or owner of such entity or arrangement) generally will depend on the status of the partner (or owner) and the activities of the partnership (or such entity or arrangement). Any entity or arrangement treated as a partnership for U.S. federal income tax purposes that holds Public Shares, and any partners in such partnership (or owners of such entity or arrangement), are urged to consult their own tax advisors with respect to the tax consequences of the redemption in their specific circumstances.

The tax consequences of a redemption of your Public Shares will depend on your specific situation. In addition, the U.S. federal income tax treatment of the exercise of redemption rights to Holders may be affected by matters not discussed herein and may depend on determinations of fact and interpretations of complex provisions of U.S. federal income tax law for which no clear precedent or authority is available. You should consult with your own tax advisor as to the tax consequences of a redemption of your Public Shares in your particular circumstances, including the applicability and effect of the alternative minimum tax, the Medicare contribution tax on net investment income, the special accounting rules under Section 451(b) of the Code, and any U.S. federal, state, or local, non-U.S., or other tax laws and of changes in those laws.

XPDB has not requested, and does not intend to request, a ruling from the IRS or an opinion of counsel as to the U.S. federal income tax consequences of the exercise of redemption rights. Consequently, no assurance can be given that the IRS will not assert, or that a court would not sustain, a position contrary to any position set forth below. Each Holder is urged to consult its tax advisor with respect to the particular tax consequences of the exercise of redemption rights to such Holder.

Tax Consequences of a Redemption of Public Shares

Tax Consequences for U.S. Holders

The discussion below applies to you if you are a U.S. Holder that exercises the redemption rights with respect to your Public Shares.

Treatment of Redemption

The treatment of a redemption of your Public Shares for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale or exchange of your Public Shares under Section 302 of the Code. If the redemption qualifies as a sale or exchange, you generally will recognize gain or loss as described below under “— Gain or Loss on Redemptions Treated as a Sale or Exchange of Public Shares.” If the redemption does not qualify as a sale or exchange, you generally will be treated as receiving a corporate distribution subject to tax as described below under “— Taxation of Redemptions Treated as Distributions.” Whether a redemption qualifies as a sale or exchange will depend largely on the total number of shares of XPDB Common Stock held or treated as held by you (including any shares constructively owned by you, as described below) relative to the number of all shares of XPDB Common Stock outstanding both before and after the redemption. The redemption of Public Shares generally will be treated as a sale or exchange of Public Shares (rather than as a corporate distribution) if the redemption (i) results in a “complete termination” of your interest in XPDB, (ii) is “not essentially equivalent to a dividend” with respect to you, or (iii) is “substantially disproportionate” with respect to you. These tests are explained more fully below.

In determining whether any of the foregoing tests are satisfied, you must take into account not only Public Shares actually owned by you, but also XPDB Common Stock that is constructively owned by you. You may constructively own, in addition to Public Shares owned directly, XPDB Common Stock owned by certain related individuals or entities in which you have an interest or that have an interest in you, as well as any XPDB Common Stock you have a right to acquire by exercise of an option (such as an XPDB public warrant to purchase Public Shares).

There will be a complete termination of your interest in XPDB if either (i) all of the XPDB Common Stock actually and constructively owned by you is redeemed or (ii) all of the XPDB Common Stock actually owned by you is redeemed and you are eligible to waive, and do effectively waive in accordance with specific rules, the attribution of XPDB Common Stock owned by certain family members and you do not constructively own any other XPDB Common Stock and you otherwise comply with specific conditions. Whether the redemption will be considered “not essentially equivalent to a dividend” with respect to you will depend upon your particular circumstances. The redemption of Public Shares generally will not be essentially equivalent to a dividend if the redemption results in a “meaningful reduction” of your proportionate interest in XPDB (including constructive ownership). Whether the redemption will result in a meaningful reduction in your proportionate interest in XPDB 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 (including constructive ownership) of a small minority stockholder in a publicly held corporation who exercises no control over its corporate affairs may constitute such a “meaningful reduction.” In order to meet the “substantially disproportionate” test, the percentage of outstanding shares of XPDB Common Stock actually and constructively owned by you immediately following the redemption must, among other requirements, be less than 80% of the percentage of the outstanding shares of XPDB Common Stock actually and constructively owned by you immediately before the redemption. You are urged to consult with your tax advisor as to the tax consequences of a redemption.

If none of the foregoing tests are satisfied, then the redemption proceeds generally will be treated as a corporate distribution and the tax effects generally will be as described under “— Taxation of Redemptions Treated as Distributions” below. After the application of those rules, any remaining tax basis you have in the redeemed Public Shares will be added to your adjusted tax basis in your remaining Public Shares, or, if you have none, to your adjusted tax basis in warrants to purchase Public Shares held by you, or possibly in other XPDB Common Stock constructively owned by you. If you hold different blocks of Public Shares (generally, Public Shares purchased or acquired on different dates or at different prices), you should consult your tax advisors to determine how the above rules apply to you.

186

Table of Contents

Taxation of Redemptions Treated as Distributions

If the redemption of your Public Shares does not qualify as a sale or exchange of your Public Shares, you generally will be treated as receiving a distribution from XPDB. You generally will be required to include in gross income as dividends the amount of proceeds received in connection with such a redemption to the extent the distribution is paid out of XPDB’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Distributions in excess of such earnings and profits generally will be treated as a return of capital that will be applied against and reduce your basis in your Public Shares (but not below zero), with any remaining excess treated as gain from the sale or exchange of such Public Shares as described below under “— Gain or Loss on Redemptions Treated as a Sale or Exchange of Public Shares.”

If you are a corporate U.S. Holder, dividends paid by XPDB to you may be eligible for the dividends-received deduction allowed to domestic corporations in respect of dividends received from other domestic corporations so long as you satisfy the holding period requirement for the dividends-received deduction.

If you are a non-corporate U.S. Holder, under tax laws currently in effect, dividends may be taxed at the applicable long-term capital gains rate, which is currently lower than the ordinary income rate, so long as you satisfy the holding period requirement (i.e., you held the Public Shares for more than sixty (60) days during the one hundred twenty-one (121) day period that begins sixty (60) days before the ex-dividend date) and certain other requirements.

However, it is possible that because of the redemption rights associated with the Public Shares, the holding period of such Public Shares may not be considered to begin until the date of such redemption or the lapse of such redemption rights (and thus it is possible that the holding period requirement will not be met as a result).

If you hold different blocks of Public Shares (generally, Public Shares purchased or acquired on different dates or at different prices), you should consult your tax advisors to determine how the above rules apply to you.

Gain or Loss on Redemptions Treated as a Sale or Exchange of Public Shares

If a redemption of your Public Shares qualifies as a sale or exchange of your Public Shares, you generally will recognize capital gain or loss in an amount equal to the difference between (i) the amount of cash received in the redemption and (ii) your adjusted tax basis in your Public Shares so redeemed.

Any such capital gain or loss may be long-term capital gain or loss if your holding period for your Public Shares so redeemed exceeds one (1) year. Long-term capital gains recognized by non-corporate U.S. Holders generally will be eligible for taxation at rates lower than rates with respect to ordinary income. The deductibility of capital losses is subject to limitations.

However, it is possible that because of the redemption rights associated with the Public Shares, the holding period of such Public Shares may not be considered to begin until the date of such redemption or the lapse of such redemption rights (and thus it is possible that long-term capital gain or loss treatment may not apply as a result).

Tax Consequences for Non-U.S. Holders

The discussion below applies to you if you are a Non-U.S. Holder that exercises the redemption rights with respect to your Public Shares.

Treatment of Redemption

If you are a Non-U.S. Holder, the U.S. federal income tax characterization of a redemption of your Public Shares generally will correspond to the U.S. federal income tax characterization of a redemption of a U.S. Holder’s Public Shares, as described above under “Tax Consequences for U.S. Holders — Treatment of Redemption.”

Non-U.S. Holders considering exercising their redemption rights are urged to consult their own tax advisors as to whether the redemption of their Public Shares will be treated as a distribution or as a sale or exchange for U.S. federal income tax purposes.

187

Table of Contents

Taxation of Redemptions Treated as Distributions

If the redemption of your Public Shares does not qualify as a sale or exchange of your Public Shares, you generally will be treated as receiving a distribution from XPDB, which distribution generally will be treated as a dividend to the extent the distribution is paid out of XPDB’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). The gross amount of such dividends generally will be subject to withholding tax at a rate of 30% unless you are eligible for a reduced rate of withholding under an applicable income tax treaty and provide proper certification of your eligibility for such reduced rate. Dividends that are effectively connected with the conduct by you of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base that you maintain in the United States) generally will be subject to U.S. federal income tax at regular U.S. federal income tax rates applicable to a comparable U.S. Holder (and generally will not be subject to such withholding tax if certain certification and disclosure requirements are satisfied) and, if you are a corporation for U.S. federal income tax purposes, may also be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate.

Distributions in excess of such earnings and profits generally will be treated as a return of capital that will be applied against and reduce your basis in your Public Shares (but not below zero), with any remaining excess treated as gain from the sale or exchange of such Public Shares, as described under “— Gain or Loss on Redemptions Treated as a Sale or Exchange of Public Shares” below.

Gain or Loss on Redemptions Treated as a Sale or Exchange of Public Shares

Subject to the discussions of backup withholding and FATCA below, if the redemption of your Public Shares qualifies as a sale or exchange of your Public Shares, you generally will not be subject to U.S. federal income tax on any gain recognized on such redemption unless:

• such gain is effectively connected with the conduct by you of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or fixed base that you maintain in the United States), in which case, you generally will be subject to U.S. federal income tax on such gain at the regular U.S. federal income tax rates applicable to a comparable U.S. Holder and, if you are a corporation for U.S. federal income tax purposes, also may be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate;

• you are an individual who is present in the United States for 183 days or more in the taxable year of the redemption and certain other conditions are met, in which case, you generally will be subject to a 30% tax on your net capital gain for the year; or

• XPDB is or has been a “U.S. real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of the five (5) year period ending on the date of the redemption or the period during which you held the redeemed Public Shares, and, in the case where the Public Shares are considered regularly traded on an established securities market for this purpose, you have owned, directly or constructively, more than 5% of the Public Shares at any time within the shorter of the five (5) year period ending on the date of the redemption or the period during which you held the redeemed Public Shares. XPDB does not believe that it is or has been a U.S. real property holding corporation.

All holders of Public Shares are urged to consult their tax advisors with respect to the tax consequences of a redemption of Public Shares in their particular circumstances, including tax return reporting requirements, the applicability and effect of the Medicare contribution tax on net investment income, the alternative minimum tax, the special accounting rules under Section 451(b) of the Code, any U.S. federal tax laws, including those other than those pertaining to income tax (including estate and gift tax laws), and any U.S. state or local, non-U.S., or other tax laws.

Information Reporting and Backup Withholding

Proceeds received in connection with a redemption of Public Shares may be subject to information reporting to the IRS and U.S. backup withholding. Copies of information returns may be made available to the tax authorities in the country in which a Non-U.S. Holder resides under the provisions of an applicable income tax treaty. Backup withholding generally will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status. A Non-U.S. Holder generally will eliminate the requirement for information reporting and backup withholding by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a Holder’s U.S. federal income tax liability, and a Holder generally may claim a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

FATCA

Sections 1471 through 1474 of the Code (commonly referred to as “FATCA”) impose withholding of thirty percent (30%) on payments of dividends (including constructive dividends received pursuant to a redemption of stock) on Public Shares. Thirty percent (30%) withholding under FATCA was scheduled to apply to payments of gross proceeds from the sale of property that produces U.S.-source interest or dividends beginning on January 1, 2019, but on December 13, 2018, the IRS released proposed Treasury Regulations that indefinitely suspended the obligation to withhold on gross proceeds. Although these proposed Treasury Regulations are not final, taxpayers generally may rely on them until final Treasury Regulations are issued.

In general, no FATCA withholding will be required with respect to a U.S. Holder or an individual Non-U.S. Holder that timely provides the certifications required on a valid IRS Form W-9 or W-8BEN, respectively.

Holders potentially subject to withholding include “foreign financial institutions” (which is broadly defined for this purpose and generally includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in, or accounts with, those entities) have been satisfied, or an exemption applies (typically certified by the delivery of a properly completed IRS Form W-8BEN-E). If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). Jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Holders should consult their tax advisors regarding the effects of FATCA on a redemption of Public Shares.

COMPARISON OF STOCKHOLDERS’ RIGHTS

General

XPDB is incorporated under the laws of the State of Delaware and the rights of XPDB stockholders are governed by the laws of the State of Delaware, including the DGCL, the Existing Charter and XPDB’s bylaws.

The Post-Combination Company will be incorporated under the laws of the State of Delaware and the rights of Post-Combination Company stockholders will be governed by the laws of the State of Delaware, including the DGCL, the Proposed Charter and the Amended and Restated Bylaws. Thus, following the Business Combination, the rights of XPDB stockholders who become Post-Combination Company stockholders in the Business Combination will continue to be governed by Delaware law but will no longer be governed by the Existing Charter and XPDB’s bylaws and instead will be governed by the Proposed Charter and the Amended and Restated Bylaws.

Comparison of Stockholders’ Rights

Set forth below is a summary comparison of material differences between the rights of XPDB stockholders under the Existing Charter and XPDB’s bylaws (left column), and the rights of Post-Combination Company stockholders under the forms of the Proposed Charter and the Amended and Restated Bylaws (right column). The summary set forth below is not intended to be complete or to provide a comprehensive discussion of such governing documents. This summary is qualified in its entirety by reference to the full text of the Existing Charter and XPDB’s bylaws, and the Proposed Charter and the Amended and Restated Bylaws, the forms of which are attached to this proxy statement/prospectus as Annex B and Annex C, respectively, as well as the relevant provisions of the DGCL.

Post-Combination Company preferred stock. The Post-Combination Company will be authorized to issue shares of preferred stock, par value $0.0001 per share. Following consummation of the Business Combination, the Post-Combination Company is not expected to have any preferred stock outstanding.

Dual Class Stock Structure. The Proposed Charter provides for a dual class stock structure in which shares of Class A Common Stock will each have one vote per share and shares of Class B Common Stock will have a number of votes per share necessary such that the Montana Equityholders collectively would own at the Closing at least 80% of the voting power of all classes of stock of the Post-Combination Company entitled to vote; provided, however, that the number of votes per share shall be at least one vote per share.

The bylaws also may be adopted, amended, altered or repealed by the affirmative vote of the holders of at least a majority of the voting power of all outstanding shares of XPDB capital stock entitled to vote, voting together as a single class.

Size of Board, Election of Directors
Size of Board. The number of directors on the XPDB Board is to be determined from time to time as provided by the bylaws of XPDB. Directors need not be stockholders or residents of the State of Delaware. Election of Directors. XPDB’s stockholders shall elect directors, each of whom shall hold office for a term of three years or until his or her successor has been elected and qualified, subject to such director’s earlier death, resignation, retirement, disqualification or removal. Prior to the Closing, the holders of XPDB Class B Common Stock shall have the exclusive right to elect and remove any director, and the holders of XPDB Class A Common Stock shall have no right to vote on the election or removal of any director. At all meetings of stockholders for the election of directors at which a quorum is present, a plurality of the votes cast shall be sufficient to elect.

XPDB		Post-Combination Company
Removal of Directors
Any director or XPDB’s entire board of directors may be removed, but only for cause, by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of XPDB capital stock entitled to vote generally in the election of directors, voting together as a single class.		Subject to the rights of holders of any series of preferred stock to elect directors, the board of directors or any individual director may be removed at any time, but only for cause and only by the affirmative vote of the holders of at least 662/3% of the voting power of the issued and outstanding shares of voting stock of the Post-Combination Company entitled to vote in the election of directors.
Board Vacancies and Newly Created Directorships
Unless otherwise provided by law or the Existing Charter, any newly created directorship or any vacancy occurring on the XPDB Board for any cause may be filled by a majority of the remaining members of the XPDB Board, even if such majority is less than a quorum, or by a sole remaining director (and not by stockholders), and any director so chosen shall hold office for the remainder of the full term of the class of directors to which the new directorship was added or in which the vacancy occurred and until his or her successor has been elected and qualified, subject, however, to such director’s earlier death, resignation, retirement, disqualification or removal.		Subject to the special rights of the holders of one or more outstanding series of preferred stock to elect directors, except as otherwise provided by law, any vacancies on the board of directors resulting from death, resignation, disqualification, retirement, removal or other causes and any newly created directorships resulting from any increase in the number of directors shall be filled exclusively by the affirmative vote of a majority of the directors then in office, even though less than a quorum, or by a sole remaining director (other than any directors elected by the separate vote of one or more outstanding series of preferred stock), and shall not be filled by the stockholders. Any director appointed in accordance with the preceding sentence shall hold office until the expiration of the term of the class to which such director shall have been appointed or until his or her earlier death, resignation, retirement, disqualification, or removal.
Corporate Opportunity/ Duties of Directors
To the maximum extent permitted under the DGCL, XPDB renounces any interest or expectancy in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to its directors who are not XPDB employees, and no such director shall be liable to XPDB or its stockholders for breach of any fiduciary or other duty by reason of the fact that such director personally or on behalf of any other person pursues or acquires such business opportunity, directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to XPDB or its subsidiaries.		The Proposed Charter does not waive the Post-Combination Company’s right to any corporate opportunity. Under Delaware law, the standards of conduct for directors have developed through Delaware court case law. Generally, directors of Delaware corporations are subject to a duty of loyalty and a duty of care. The duty of loyalty requires directors to refrain from self-dealing, and the duty of care requires directors in managing the Post-Combination Company’s affairs to use that level of care which ordinarily careful and prudent persons would use in similar circumstances. When directors act consistently with their duties of loyalty and care, their decisions generally are presumed to be valid under the business judgment rule.

XPDB		Post-Combination Company
Exclusive Forum
The Existing Charter designates the Court of Chancery of the State of Delaware as the exclusive forum for (i) any derivative action or proceeding brought on behalf of XPDB, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of XPDB to XPDB or its stockholders, (iii) any action asserting a claim against XPDB, its directors, officers or employees arising pursuant to any provision of the DGCL the bylaws of XPDB or the Existing Charter, or (iv) any action asserting a claim against XPDB, its directors, officers or employees governed by the internal affairs doctrine, except for, as to each of (i) through (iv) above, (A) any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery. And (B) brought under the Securities Act, Exchange Act or for which federal courts have exclusive jurisdiction. The Existing Charter further provides that the federal courts have exclusive jurisdiction over suits brought to enforce any liability or duty created by the Exchange Act or for which the federal courts have exclusive jurisdiction.		Unless the Post-Combination Company consents in writing to the selection of an alternative forum, the Post-Combination Company’s charter designates the Court of Chancery of the State of Delaware (or in the event that the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) to the fullest extent permitted by applicable law, as the sole and exclusive forum for any stockholder (including a beneficial owner) to bring (i) any derivative action, suit or proceeding brought on behalf of the Post-Combination Company, (ii) any claim of breach of a fiduciary duty owed by any of the Post-Combination Company’s directors, officers or employees to the Post-Combination Company or its stockholders, (iii) any claim against the Post-Combination Company arising pursuant to any provision of the Post-Combination Company’s charter, bylaws or the DGCL, or (iv) any action asserting a claim against the Post-Combination Company, its directors, officers or employees, as governed by the internal affairs doctrine. The Proposed Charter designates the federal district courts of the United States of America as the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, including all causes of action asserted against any defendant to such complaint. Notwithstanding the foregoing, the forum selection provisions of the Proposed Charter will not apply to any suits brought to enforce any liability or duty created by the Exchange Act, as amended, or any other claim for which the federal courts of the United States have exclusive jurisdiction.
Limitation of Liability of Directors and Officers
A XPDB director shall not be personally liable to XPDB or its stockholders for monetary damages for breach of fiduciary duty owed to XPDB and its stockholders, except for (i) for any breach of the director’s duty of loyalty to XPDB or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. Neither the amendment nor appeal of this provision in the Existing Charter nor, to the fullest extent permitted by the DGCL, any modification of law shall adversely affect any right or protection of an XPDB director in respect of any act or omission occurring prior to the time of such amendment, modification or repeal.		No director or officer of the Post-Combination Company shall be personally liable to the Post-Combination Company or its stockholders for monetary damages for breach of fiduciary duty owed to the Post-Combination Company and its stockholders, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or hereafter may be amended. Neither the amendment, repeal or modification of this provision in the Proposed Charter, nor to the fullest extent permitted by the DGCL, any modification of law, shall adversely affect any right or protection of a director or officer of the Post-Combination Company with respect to any act or omission occurring prior to such amendment, repeal or modification. If the DGCL is amended after approval by the stockholders of this provision to authorize corporate action further eliminating or limiting personal liability of directors, then the liability of directors of the Post-Combination Company shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Indemnification and Advancement Directors, Officers, Employees and Agents

XPDB will indemnify and hold harmless any person who is or was made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of being a director or officer of XPDB or, while a director or officer, is or was serving at the request of XPDB as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise or non-profit entity, including service with respect to an employee benefit plan.

The right to indemnification covers all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred by such indemnitee in connection with such proceeding. It also includes the right to be paid by XPDB the expenses (including attorney’s fees) incurred in defending or otherwise participating in any such proceeding in advance of its final disposition, provided, however, that, to the extent required by applicable law, an advancement of expenses will be made only upon delivery to XPDB of an undertaking, by or on behalf of the indemnitee, to repay all amounts so advanced if it will ultimately be determined that the indemnitee is not entitled to be indemnified for the expenses.

Such rights will continue as to an indemnitee who has ceased to be a director, officer, employee or agent and will inure to the benefit of his or her heirs, executors and administrators.

Notwithstanding the foregoing, except for proceedings to enforce rights to indemnification and advancement of expenses, XPDB shall indemnify and advance expenses to an indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by XPDB’s Board.

The Post-Combination Company will indemnify and hold harmless, to the fullest extent permitted by the DGCL, any director or officer of the Post-Combination Company for any proceeding by reason of the fact that such person is or was a director or officer of the Post-Combination Company or, while a director or officer, is or was serving at the request of the Post-Combination Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans against all liability and loss suffered and expenses reasonably incurred by such person in connection with any such proceeding.

The Post-Combination Company has the power to indemnify and hold harmless, to the fullest extent permitted by the DGCL or any other applicable law, any employee or agent of the Post-Combination Company who was or is made or is threatened to be made a party or is otherwise involved in a proceeding by reason of the fact that he or she, or a person whom he or she is the legal representative, is or was an employee or agent of the Post-Combination Company or is or was serving at the request of the Post-Combination Company as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or non-profit entity against all liability and loss suffered and expenses reasonably incurred by such person in connection with any such proceeding.

The right to indemnification covers all liability and loss suffered and expenses (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) actually and reasonably incurred by such person in connection with any such proceeding.

DESCRIPTION OF SECURITIES OF THE POST-COMBINATION COMPANY

In connection with the Business Combination, the Post-Combination Company will amend and restate its charter and bylaws. The following is a description of the material terms of, and is qualified in its entirety by, the Proposed Charter and the Amended and Restated Bylaws, each of which will be in effect upon the consummation of the Business Combination, the forms of which are attached as Annex B and Annex C to this proxy statement/prospectus, respectively.

The Post-Combination Company’s purpose will be to engage in any lawful act or activity for which corporations may now or hereafter be organized under the DGCL. Upon the consummation of the Business Combination, the Post-Combination Company’s authorized capital stock will consist of shares of Class A Common Stock, par value $0.0001 per share, shares of Class B Common Stock, par value $0.0001 per share and shares of preferred stock, par value $0.0001 per share. We do not anticipate that any shares of preferred stock will be issued or outstanding immediately after the Business Combination. Unless the Post-Combination Company Board determines otherwise, the Post-Combination Company will issue all shares of its capital stock in uncertificated form.

Common Stock

As of June 30, 2023, XPDB had 10,608,178 shares of XPDB Class A Common Stock and 7,187,500 shares of XPDB Class B Common Stock issued and outstanding, including one holder of record of XPDB Class A Common Stock and four holders of record of XPDB Class B Common Stock. After giving effect to the Business Combination, in the Assuming No Redemptions Scenario, we expect the Post-Combination Company will have approximately 55,741,006 shares of common stock outstanding, consisting of (i) 37,945,328 shares issued to holders of Montana Class A Common Units and Montana Class B Common Units, (ii) 10,608,178 shares held by XPDB Public Stockholders (assuming no redemptions by such XPDB Public Stockholders) (iii) 7,097,500 shares held by our Anchor Investors and the Sponsor (including up to 1,380,736 shares subject to vesting and earnout requirements pursuant to the Sponsor Support Agreement) and (iv) 90,000 shares held by the independent directors of XPDB.

Class A Common Stock

Voting rights. Each holder of Class A Common Stock will be entitled to one vote for each share of Class A Common Stock held of record in person or by proxy on all matters submitted to a vote of the holders of Class A Common Stock, whether voting separately as a class or otherwise.

Dividend rights. Subject to applicable law and the rights and preferences of any holders of any outstanding series of preferred stock or any class or series of stock having a preference over or the right to participate with the Class A Common Stock with respect to the payment of dividends, holders of Class A Common Stock, as such, shall be entitled to the payment of dividends on the Class A Common Stock when, as and if declared by the Post-Combination Company Board in accordance with applicable law. Dividends of cash or property may not be declared or paid on Class A Common Stock unless a dividend of the same amount per share and same type of cash or property (or combination thereof) per share is concurrently declared or paid on all other classes of common stock of the Post-Combination Company.

The payment of future dividends on the shares of Class A Common Stock will depend on the financial condition of the Post-Combination Company after the completion of the Business Combination and payment thereof will be subject to the discretion of the Post-Combination Company Board. The Post-Combination Company currently intends to retain all available funds and any future earnings to fund the development and growth of the business, and therefore does not anticipate declaring or paying any cash dividends on capital stock of the Post-Combination Company in the foreseeable future. The ability of the Post-Combination Company to declare dividends may be limited by the terms and conditions of other financing and other agreements entered into by the Post-Combination Company or any of its subsidiaries from time to time.

Rights upon liquidation. Subject to the rights and preferences of any holders of any shares of any outstanding series of preferred stock, in the event of any liquidation, dissolution or winding up of the Post-Combination Company, whether voluntary or involuntary, the funds and assets of the Post-Combination Company that may be legally distributed to the Post-Combination Company’s stockholders will be distributed among the holders of the then outstanding common stock of the Post-Combination Company pro rata in accordance with the number of shares of common stock of the Post-Combination Company held by each such holder.

198

Table of Contents

Other rights. The holders of Class A Common Stock will not have pre-emptive or conversion rights or other subscription rights. There will not be any redemption or sinking fund provisions applicable to the Class A Common Stock. The rights, preferences and privileges of holders of the Class A Common Stock will be subject to those of the holders of any shares of the preferred stock that the Post-Combination Company may issue in the future.

Class B Common Stock

Voting rights. Each holder of Class B Common Stock will be entitled to a number of votes per share necessary such that the Montana Equityholders collectively would own at the Closing at least 80% of the voting power of all classes of stock of the Post-Combination Company entitled to vote; provided, however, that the number of votes per share shall be at least one vote per share.

Dividend rights. Subject to applicable law and the rights and preferences of any holders of any outstanding series of preferred stock or any class or series of stock having a preference over or the right to participate with the Class B Common Stock with respect to the payment of dividends, holders of Class B Common Stock, as such, shall be entitled to the payment of dividends on the Class B Common Stock when, as and if declared by the Post-Combination Company Board in accordance with applicable law. Dividends of cash or property may not be declared or paid on Class B Common Stock unless a dividend of the same amount per share and same type of cash or property (or combination thereof) per share is concurrently declared or paid on all other classes of common stock of the Post-Combination Company.

The payment of future dividends on the shares of Class B Common Stock will depend on the financial condition of the Post-Combination Company after the completion of the Business Combination and payment thereof will be subject to the discretion of the Post-Combination Company Board. The Post-Combination Company currently intends to retain all available funds and any future earnings to fund the development and growth of the business, and therefore does not anticipate declaring or paying any cash dividends on capital stock of the Post-Combination Company in the foreseeable future. The ability of the Post-Combination Company to declare dividends may be limited by the terms and conditions of other financing and other agreements entered into by the Post-Combination Company or any of its subsidiaries from time to time.

Other rights. The holders of Class B Common Stock will not have pre-emptive or conversion rights or other subscription rights. There will not be any redemption or sinking fund provisions applicable to the Class B Common Stock. The rights, preferences and privileges of holders of the Class B Common Stock will be subject to those of the holders of any shares of the preferred stock that the Post-Combination Company may issue in the future.

Permitted Ownership. From and after the effectiveness of the Proposed Charter with the Secretary of State of the State of Delaware, shares of Class B Common Stock may be issued only to, and registered only in the name of, Matthew Jore and Stu Porter and their respective permitted transferees (the “Permitted Class B Owners”).

Voluntary Conversion. Each share of Class B Common Stock will be convertible into one share of Class A Common Stock at the option of the holder thereof at any time upon written notice to the transfer agent of the Post-Combination Company. Shares of Class B Common Stock that are voluntarily converted into shares of Class A Common Stock will be retired and may not be reissued.

Automatic Conversion. On the earliest to occur of (i) the date that is seven years from the effective date of the Proposed Charter and (ii) the first date on which the Permitted Class B Owners cease to own, in the aggregate, at least 33.0% of the number of shares of Class B Common Stock issued and held by the Permitted Class B Owners immediately following the filing of the Proposed Charter with the Secretary of State of the State of Delaware (or as to which the Permitted Class B Owners are entitled to as of such time), in each case, as equitably adjusted to reflect any stock splits, reverse stock splits, stock dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change or transaction (such date, the “Automatic Conversion Date”), each outstanding

199

Table of Contents

share of Class B Common Stock will automatically, without any further action by the Post-Combination Company or any stockholder thereof, convert into one fully paid and non-assessable share of Class A Common Stock. Following such conversion, the reissuance of all shares of Class B Common Stock will be prohibited, and such shares of Class B Common Stock will be retired and may not be reissued. Upon such retirement, all references to Class B Common Stock in the Proposed Charter will be eliminated. The Post-Combination Company will provide notice of any automatic conversion of shares of Class B Common Stock to record holders of such shares of Class B Common Stock as soon as practicable following such conversion. Alternatively, the Post-Combination Company may satisfy such notice requirement by providing such notice prior to the automatic conversion.

Conversion upon transfer. Immediately prior to any transfer of shares of Class B Common Stock to a person other than a permitted transferee of the Permitted Class B Owners, each share of Class B Common Stock being transferred will automatically, without any further action by the Post-Combination Company, any stockholder thereof, the transferor or the transferee, convert into one fully paid and non-assessable share of Class A Common Stock.

Effect of Conversion. In the event of a conversion of shares of Class B Common Stock into shares of Class A Common Stock, such conversion(s) will be deemed to have been made at the time that the transfer of shares occurred or immediately upon the Automatic Conversion Date, as applicable. Upon any conversion of Class B Common Stock to Class A Common Stock, all rights of the former holder of such shares of Class B Common Stock with respect to such shares of Class B Common Stock will cease and the person or persons in whose names or names the certificate or certificates representing the shares of Class A Common Stock are to be issued shall be treated for all purposes as having become the record holder or holders of such shares of Class A Common Stock.

Conversion Procedures. The Post-Combination Company will be entitled, from time to time, establish such policies and procedures relating to the conversion of Class B Common Stock into Class A Common Stock and the general administration of the Post-Combination Company’s dual class stock structure, including the issuance of stock certificates with respect thereto, as it may deem reasonably necessary or advisable, and may from time to time request that holders of shares of Class B Common Stock furnish certifications, affidavits or other proof to the Post-Combination Company as it deems necessary to verify the ownership of Class B Common Stock and to confirm that a conversion to Class A Common Stock has not occurred. A determination by the Secretary of the Post-Combination Company that a transfer results in a conversion to Class A Common Stock will be conclusive and binding.

Preferred Stock

Under the terms of the Proposed Charter, the Post-Combination Company Board is authorized to issue shares of preferred stock in one or more series without stockholder approval. The Post-Combination Company Board has the discretion to determine the rights, powers, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

Unless required by law or any stock exchange, the authorized shares of preferred stock will be available for issuance without further action by the stockholders of the Post-Combination Company. The purpose of authorizing the Post-Combination Company Board to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of the outstanding voting stock. Additionally, the issuance of preferred stock may adversely affect the holders of Class A Common Stock by restricting dividends on the Class A Common Stock, diluting the voting power of the common stock or subordinating the liquidation rights of the Class A Common Stock. As a result of these or other factors, the issuance of preferred stock could have an adverse impact on the market price of the Class A Common Stock.

Anti-Takeover Provisions

The Proposed Charter and the Amended and Restated Bylaws will contain provisions that may delay, defer or discourage another party from acquiring control of us. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with the Post-Combination Company Board,

200

Table of Contents

which may result in an improvement of the terms of any such acquisition in favor of the stockholders. However, they also give the Post-Combination Company Board the power to discourage acquisitions that some stockholders may favor.

Authorized but Unissued Shares

The authorized but unissued shares of Post-Combination Company common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of Nasdaq. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Classified Board of Directors

The Proposed Charter provides that the Post-Combination Company Board will be divided into three classes of directors, with the classes to be as nearly equal in number as possible, and with each director serving a three-year term. As a result, approximately one-third of the Post-Combination Company Board will be elected each year. The classification of directors will have the effect of making it more difficult for stockholders to change the composition of the Post-Combination Company Board.

Stockholder Action; Special Meetings of Stockholders

The Proposed Charter will provide that stockholders may not take action by written consent, but may only take action at annual or special meetings of stockholders. As a result, a holder controlling a majority of Post- Combination Company capital stock would not be able to amend the Amended and Restated Bylaws or remove directors without holding a meeting of stockholders called in accordance with the Amended and Restated Bylaws. Further, the Proposed Charter will provide that only the chairperson of Post-Combination Company Board, the Chief Executive Officer or the President of the Post-Combination Company may call special meetings of stockholders, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of stockholders to force consideration of a proposal or for stockholders controlling a majority of Post-Combination Company capital stock to take any action, including the removal of directors.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

In addition, the Amended and Restated Bylaws will establish an advance notice procedure for stockholder proposals to be brought before an annual meeting or special meeting of stockholders. Generally, in order for any matter to be “properly brought” before a meeting, the matter must be (a) specified in a notice of meeting given by or at the direction of the Post-Combination Company Board, (b) if not specified in a notice of meeting, otherwise brought before the meeting by the board of directors or the chairperson of the meeting, or (c) otherwise properly brought before the meeting by a stockholder present in person who (1) was a stockholder both at the time of giving the notice and at the time of the meeting, (2) is entitled to vote at the meeting, and (3) has complied with the advance notice procedures specified in the Amended and Restated Bylaws or properly made such proposal in accordance with Rule 14a-8 under the Exchange Act and the rules and regulations thereunder, which proposal has been included in the proxy statement for the annual meeting. Further, for business to be properly brought before an annual meeting by a stockholder, the stockholder must (a) provide Timely Notice (as defined below) thereof in writing and in proper form to the secretary of the Post-Combination Company and (b) provide any updates or supplements to such notice at the times and in the forms required by the Amended and Restated Bylaws. To be timely, a stockholder’s notice must be delivered to, or mailed and received at, the Post-Combination Company’s principal executive offices not less than 90 days nor more than 120 days prior to the one-year anniversary of the preceding year’s annual meeting; provided, however, that if no annual meeting was held in the preceding year, to be timely, a stockholder’s notice must be so delivered, or mailed and received, not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting, or, if later, the 10th day following the day on which public disclosure of the date of such annual meeting was first made by the corporation; provided, further, that if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date,

201

Table of Contents

notice by the stockholder to be timely must be so delivered, or mailed and received, not later than the 90th day prior to such annual meeting or, if later, the 10th day following the day on which public disclosure of the date of such annual meeting was first made (such notice within such time periods, “Timely Notice”). In no event shall any adjournment or postponement of an annual meeting or the announcement thereof commence a new time period for the giving of Timely Notice as described above.

Stockholders at an annual meeting or special meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the Post-Combination Company Board or by a qualified stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely written notice in proper form to the Post-Combination Company’s secretary of the stockholder’s intention to bring such business before the meeting. These provisions could have the effect of delaying stockholder actions that are favored by the holders of a majority of the outstanding voting securities until the next stockholder meeting.

Amendment of Charter or Bylaws

Upon consummation of the Business Combination, the Amended and Restated Bylaws may be amended or repealed by the Post-Combination Company Board. In addition to any vote of the holders of any class or series of stock of the Post-Combination Company required by applicable law or by the Proposed Charter or the Amended and Restated Bylaws, the adoption, amendment or repeal of the Amended and Restated Bylaws shall require the affirmative vote of the holders of at least sixty-six and two-thirds percent (662/3%) of the voting power of all of the then outstanding shares entitled to vote generally in the election of directors, voting together as a single class. The affirmative vote of holders of at least sixty-six and two-thirds percent (662/3%) of the total voting power of the then outstanding shares entitled to vote thereon, voting together as a single class, would be required to amend certain provisions of the Proposed Charter.

Limitations on Liability and Indemnification of Officers and Directors

The Amended and Restated Bylaws will provide indemnification and advancement of expenses for the Post-Combination Company’s directors and officers to the fullest extent permitted by the DGCL, subject to certain limited exceptions. The Post-Combination Company expects to enter into, in connection with the Closing, customary, indemnification agreements with each of its directors and officers. In some cases, the provisions of those indemnification agreements may be broader than the specific indemnification provisions contained under Delaware law. In addition, as permitted by Delaware law, the Proposed Charter will include provisions that eliminate the personal liability of directors for monetary damages resulting from breaches of certain fiduciary duties as a director. The effect of this provision is to restrict the Post-Combination Company’s rights and the rights of the Post-Combination Company’s stockholders in derivative suits to recover monetary damages against a director for breach of fiduciary duties as a director.

These provisions may be held not to be enforceable for violations of the federal securities laws of the United States.

Transfer Restrictions

Pursuant to the Lock-Up Agreements, the form of which is attached to this proxy statement/prospectus as Annex G, the parties thereto will be subject to certain restrictions on transfer with respect to the shares of common stock issued as part of the Merger Consideration beginning at Closing and ending on the date that is six months after the completion of the Business Combination.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, the Post-Combination Company’s stockholders will have appraisal rights in connection with a merger or consolidation of the Post-Combination Company. Pursuant to Section 262 of the DGCL, stockholders who properly demand and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

202

Table of Contents

Stockholders’ Derivative Actions

Under the DGCL, any of the Post-Combination Company’s stockholders may bring an action in the company’s name to procure a judgment in its favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of the Post-Combination Company’s shares at the time of the transaction to which the action relates.

Forum Selection

The Proposed Charter will provide that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for: (i) any derivative action brought by a stockholder on behalf of the Post-Combination Company, (ii) any claim of breach of a fiduciary duty owed by any of the Post-Combination Company’s directors, officers, stockholders or employees, (iii) any claim against the Post-Combination Company arising under its charter, bylaws or the DGCL or (iv) any claim against the Post-Combination Company governed by the internal affairs doctrine. The Proposed Charter designates the federal district courts of the United States of America as the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. Notwithstanding the foregoing, the provisions of Article VIII of the Proposed Charter shall not apply to any suits brought to enforce any liability or duty created by the Exchange Act, as amended, or any other claim for which the federal courts of the United States have exclusive jurisdiction.

Transfer Agent and Registrar

The transfer agent and registrar for the XPDB Class A Common Stock and XPDB Class B Common Stock is Continental Stock Transfer & Trust Company.

Trading Symbol and Market

We intend to apply to list the Class A Common Stock on the Nasdaq under the symbol “AIRJ.”

Warrants

XPDB Public Warrants

Upon the Closing, each whole warrant will entitle the registered holder to purchase one share of Post-Combination Company common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the Closing. However, no warrants will be exercisable for cash unless we have an effective and current registration statement covering the shares of Post-Combination Company common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of Post-Combination Company common stock. Notwithstanding the foregoing, if a registration statement covering the shares of Post-Combination Company common stock issuable upon exercise of the XPDB public warrants is not effective within a specified period following the Closing, warrant holders may, until such time as there is an effective registration statement and during any period when we shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis, and the warrants may have no value and expire worthless. In the event, however, of such cashless exercise, each holder would pay the exercise price by surrendering the warrants for that number of shares of Post-Combination Company common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Post-Combination Company common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average last reported sale price of the shares of Post-Combination Company common stock as reported during the 10 trading day period ending on the trading day prior to the date on which the notice of redemption is sent to the holders of the warrants. The warrants will expire on the fifth anniversary of the Closing at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

203

Table of Contents

The Post-Combination Company may call the warrants for redemption, in whole and not in part, at a price of $0.01 per warrant,

• at any time after the warrants become exercisable;

• upon not less than 30 days’ prior written notice of redemption to each warrant holder; and

• if, and only if, the reported last sale price of the shares of Post-Combination Company common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations), for any 20 trading days within a 30 trading day period commencing at any time after the warrants become exercisable and ending on the third business day prior to the notice of redemption to warrant holders.

If and when the XPDB public warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. However, unless we have elected to require warrant holders to exercise such warrants on a cashless basis, we will not redeem the XPDB public warrants unless an effective registration statement under the Securities Act covering the shares of the Post-Combination Company common stock issuable upon exercise of the XPDB public warrants is effective and a current prospectus relating to those shares of the Post-Combination Company common stock is available throughout the 30-day redemption period.

The right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant.

The redemption criteria for the Post-Combination Company’s warrants have been established at a price which is intended to provide warrant holders a reasonable premium to the initial exercise price and provide a sufficient differential between the then- prevailing share price and the warrant exercise price so that if the share price declines as a result of the Post-Combination Company’s redemption call, the redemption will not cause the share price to drop below the exercise price of the warrants. If the foregoing conditions are satisfied and we issue a notice of redemption of the XPDB public warrants, each warrant holder will be entitled to exercise his, her or its XPDB public warrant prior to the scheduled redemption date. Unless we have elected to require warrant holders to exercise the warrants on a cashless basis, any such exercise would require the exercising warrant holder to pay the exercise price for each warrant being exercised. However, the price of the Post-Combination Company common stock may fall below the $18.00 redemption trigger price (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued).

The Post-Combination Company’s management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of Post-Combination Company common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Post-Combination Company common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average last reported sale price of the shares of Post-Combination Company common stock as reported during the 10 trading day period ending on the trading day prior to the date on which the notice of redemption is sent to the holders of the warrants.

The warrants were issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and XPDB. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder (i) to cure any ambiguity or correct any mistake, including to conform the provisions of the warrant agreement to the description of the terms of the warrants and the warrant agreement set forth in the XPDB IPO prospectus, or (ii) to add or change any provisions with respect to matters or questions arising under the warrant agreement as the parties to the warrant agreement may deem necessary or desirable and that the parties deem to not adversely affect the rights of the registered holders of the warrants. The warrant agreement requires the approval, by written consent, of the holders of at least 50% of the then outstanding XPDB public warrants in order to make any change that adversely affects the rights of the registered holders.

204

Table of Contents

The exercise price and number of shares of Post-Combination Company common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary dividend or the Post-Combination Company’s recapitalization, reorganization, merger or consolidation. However, except as described below, the warrants will not be adjusted for issuances of shares of Post-Combination Company common stock at a price below their respective exercise prices.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of shares of Post-Combination Company common stock and any voting rights until they exercise their warrants and receive shares of Post-Combination Company common stock. After the issuance of shares of Post-Combination Company common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Warrant holders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrant holder would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder would beneficially own in excess of 9.8% of the shares of Post-Combination Company common stock issued and outstanding.

No fractional share of common stock will be issued upon the exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number the number of shares of Post-Combination Company common stock to be issued to such warrant holder.

We have agreed that, subject to applicable law, any action, proceeding or claim against us arising out of or relating in any way to the warrant agreement, will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and we irrevocably submit to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim. This exclusive forum provision shall not apply to suits brought to enforce a duty or liability created by the Exchange Act, or any other claim for which the federal district courts of the United States of America are the sole and exclusive forum.

Private Placement Warrants

The Private Placement Warrants (including the Post-Combination Company common stock issuable upon exercise of the Private Placement Warrants) will not be transferable, assignable or saleable until 30 days after the Closing (except, among other limited exceptions, to the Post-Combination Company’s officers and directors and other persons or entities affiliated with the Sponsor and the Anchor Investors) and they will not be redeemable by the Post-Combination Company. Except as described below, the Private Placement Warrants have terms and provisions that are identical to those of the public Warrants, including as to exercise price, exercisability and exercise period.

If holders of the Private Placement Warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering their warrants for that number of shares of Post-Combination Company common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Post-Combination Company common stock underlying the warrants multiplied by the excess of the “10 day average closing price” (defined below) as of the date prior to the date on which notice of exercise is sent or given to the warrant agent, less the warrant exercise price by (y) the 10 day average closing price. The “10 day average closing price” means, as of any date, the average last reported sale price (defined below) of the shares of Post-Combination Company common stock as reported during the 10 trading day period ending on the trading day prior to such date. “Last reported sale price” means the last reported sale price of the Post-Combination Company common stock on the date on which the notice of exercise of the warrant is sent to the warrant agent.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Certain Relationships and Related Person Transactions — Post-Combination Company

Registration Rights Agreement

The Merger Agreement contemplates that, at the Closing, the Post-Combination Company, Sponsor, the Anchor Investors and certain Montana Equityholders will enter into the Registration Rights Agreement, pursuant to which the Post-Combination Company will agree to register for resale, pursuant to Rule 415 under the Securities Act, certain shares of Class A Common Stock and other equity securities of the Post-Combination Company that are held by the parties thereto from time to time. Pursuant to the Registration Rights Agreement, the Post-Combination Company will agree to file a shelf registration statement registering the resale of the Registrable Securities under the Registration Rights Agreement within 30 days after the execution of the Registration Rights Agreement, At any time and from time to time when an effective shelf registration is on file with the SEC, certain legacy Montana Equityholders and legacy Sponsor stockholders may request to sell all or any portion of their Registrable Securities in an underwritten offering so long as the total offering price is reasonably expected to exceed $25.0 million. The Post-Combination Company will also agree to provide customary “piggyback” registration rights, subject to certain requirements and customary conditions. The Registration Rights Agreement also provides that the Post-Combination Company will pay certain expenses relating to such registrations and indemnify the stockholders against certain liabilities.

Procedures with Respect to Review and Approval of Related Person Transactions

The XPDB Board and the board of managers of Montana recognize the fact that transactions with related persons present a heightened risk of conflicts of interests (or the perception thereof). Effective upon the consummation of the Business Combination, the Post-Combination Company Board expects to adopt a written policy on transactions with related persons that is in conformity with the requirements for issuers having publicly held common stock that is listed on the Nasdaq. Under the policy, the Post-Combination Company’s legal team will be primarily responsible for developing and implementing processes and procedures to obtain information regarding related persons with respect to potential related person transactions and then determining, based on the facts and circumstances, whether such potential related person transactions do, in fact, constitute related person transactions requiring compliance with the policy. If the legal team determines that a transaction or relationship is a related person transaction requiring compliance with the policy, the Post-Combination Company’s general counsel will be required to present to the audit committee all relevant facts and circumstances relating to the related person transaction. The audit committee will be required to review the relevant facts and circumstances of each related person 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 and the extent of the related person’s interest in the transaction, take into account the conflicts of interest and corporate opportunity provisions of the Post-Combination Company’s code of business conduct and ethics (which will also be put in place in connection with the Business Combination), and either approve or disapprove the related person transaction. If advance audit committee approval of a related person transaction requiring the audit committee’s approval is not feasible, then the transaction may be preliminarily entered into by management upon prior approval of the transaction by the chair of the audit committee, subject to ratification of the transaction by the audit committee at the audit committee’s next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction. If a transaction was not initially recognized as a related person transaction, then, upon such recognition, the transaction will be presented to the audit committee for ratification at the audit committee’s next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction. The Post-Combination Company’s management will update the audit committee as to any material changes to any approved or ratified related person transaction and will provide a status report at least annually of all then current related person transactions. No director will be permitted to participate in approval of a related person transaction for which he or she is a related person.

Certain Relationships and Related Person Transactions — Montana

Consulting Agreements

Montana is a party to a consulting agreement, dated as of January 1, 2019, with MRJ, LLC, which is owned by Mr. Jore, the Chief Executive Officer of Montana, pursuant to which Montana engaged MRJ, LLC to provide certain consulting services to Montana in connection with the development and sales of Montana’s technologies and products. Under the terms of the consulting agreement, Montana is responsible for a base fee to the consultant of $20,000 per month.

Montana is party to a consulting agreement, dated as of April 9, 2021, with Doxey Capital LLC, which is owned by Mr. Gutke, the Chief Financial Officer of Montana, pursuant to which Montana engaged Doxey Capital LLC to provide certain consulting services to Montana in connection with the activities, responsibilities and functions associated with the role of Chief Financial Officer. Under the terms of the consulting agreement, Montana is responsible for a consulting fee equal to $20,000 per month.

Director and Officer Indemnification

Montana’s Third Amended and Restated Operating Agreement provides for indemnification and of all reasonable expenses incurred for its managers and officers to the fullest extent permitted by the law, subject to certain limited exceptions.

Series B Preferred Investment

In October 2022, James Pallotta, a beneficially owner of greater than five percent of Montana, purchased 7,368 Montana Series B Preferred Units for an aggregate purchase price of approximately $425,581.

Certain Relationships and Related Person Transactions — XPDB

Sponsor and Anchor Investors

On March 30, 2021, the Sponsor purchased 7,187,500 Founder Shares for an aggregate purchase price of $25,000, or approximately $0.004 per share. The per share price of the Founder Shares was determined by dividing the amount of cash contributed to the Company by the number of Founder Shares issued. The number of Founder Shares issued was determined based on the expectation that the Founder Shares would represent 20% of the outstanding shares of XPDB Common Stock upon completion of the XPDB IPO. The Sponsor has also agreed that in the event of such purchase by the Anchor Investors, the Sponsor will forfeit to us for no consideration a number of Founder Shares equal to the number of Founder Shares purchased by the Anchor Investors.

In July 2021, the Sponsor transferred 30,000 Founder Shares to each of the four independent director nominees, a total of shares of 120,000 XPDB Class B Common Stock. In November 2021, the Sponsor repurchased 30,000 Founder Shares from a former independent director nominee. The number of Founder Shares issued was determined based on the expectation that such Founder Shares would represent 20% of the outstanding shares upon completion of the XPDB IPO. The Founder Shares (including the XPDB Class A Common Stock issuable upon exercise thereof) may not, subject to certain limited exceptions, be transferred, assigned or sold by the holder. The Sponsor and the Anchor Investors purchased an aggregate of 11,125,000 Private Placement Warrants for a purchase price of $1.00 per warrant in the Private Placement that occurred simultaneously with the closing of the XPDB IPO, 8,900,000 of which were purchased by the Sponsor. Therefore, the Sponsor’s interest in this transaction attributable to the Private Placement Warrants is valued at between $890,000 and $8,900,000 (based upon the closing price of $0.10 per XPDB public warrant on the Nasdaq on September 29, 2023, and the purchase price of $1.00 per Private Placement Warrant, respectively). Each Private Placement Warrant entitles the holder thereof to purchase one share of XPDB Class A Common Stock at a price of $11.50 per share. The Private Placement Warrants (including the XPDB Class A Common Stock issuable upon exercise thereof) may not, subject to certain limited exceptions, be transferred, assigned or sold by the holder.

207

Table of Contents

The Anchor Investors have also agreed that if, in connection with the Business Combination, the Sponsor decides (i) to forfeit (other than the Sponsor’s contemplated forfeiture to us described above in this section), transfer to a third person, exchange, subject to transfer, vesting or conditional forfeiture provisions or amend the terms of all or any portion of the Founder Shares or the Private Placement Warrants or (ii) to enter into any other arrangements with respect to the Founder Shares or the Private Placement Warrants, including voting in favor of any amendment to the terms of the Founder Shares or the Private Placement Warrants (each, a “Change In Investment”), such Change In Investment shall apply pro rata to the Anchor Investors and the Sponsor based on the relative number of Founder Shares or Private Placement Warrants to be held by the Sponsor (after giving effect to the Sponsor’s contemplated forfeiture to us described above in this section) upon completion of the Business Combination; provided, however that in no event will such change in investment apply to more than 75% of the Founder Shares to be purchased by the Anchor Investors (but for the avoidance of doubt may apply to up to 100% of the Private Placement Warrants to be purchased by the Anchor Investors).

There can be no assurance that the Anchor Investors will retain any Public Shares upon the completion of our initial business combination. The Anchor Investors will have the same rights to the funds held in the Trust Account with respect to the XPDB Common Stock underlying the units they purchased in the XPDB IPO as the rights afforded to our XPDB Public Stockholders.

XPDB currently maintains its executive offices at 321 North Clark Street Suite 2440 Chicago, IL 60654. Commencing on December 9, 2021, XPDB agreed to pay affiliates of our Sponsor a total of $20,000 per month for office space, utilities and secretarial and administrative support for each month since the XPDB IPO that will be paid at the consummation of the Business Combination. Upon completion of the Business Combination or liquidation, XPDB will cease paying these monthly fees.

Promissory Notes

The Sponsor agreed to loan XPDB an aggregate of up to $300,000 to cover expenses related to the XPDB IPO pursuant to a promissory note (as amended and restated on July 1, 2021). This promissory note was non-interest bearing and payable upon the completion of the XPDB IPO. As of December 14, 2021, XPDB had borrowed approximately $115,000 under the promissory note. XPDB fully repaid the promissory note on December 17, 2021.

In addition, in order to finance transaction costs in connection with an intended initial business combination, the Sponsor or affiliates of the Sponsor or certain of XPDB’s officers and directors may, but are not obligated to, loan XPDB funds as may be required. If XPDB completes an initial business combination, XPDB would repay such loaned amounts. In the event that the initial business combination does not close, XPDB may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from the Trust Account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the Private Placement Warrants, including as to exercise price, exercisability and exercise period. The terms of such loans by XPDB’s officers and directors, if any, have not been determined and no written agreements exist with respect to such loans. XPDB does not expect to seek loans from parties other than the Sponsor or affiliates of the Sponsor as XPDB does not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in the Trust Account.

Advisory, Consulting and Service Fees

In connection with the Business Combination, XPDB may potentially make a cash payment in an aggregate amount of up to $3,000,000 to XMS Capital, TEP or their respective affiliates for financial advisory services, placement agency or other similar investment banking or consulting services that XMS Capital, TEP or their respective affiliates may provide to XPDB in connection with the Business Combination, including offering objective, independent analysis and advice to XPDB as it evaluates, structures and negotiates the Business Combination. Additionally, XPDB may reimburse to XMS Capital, TEP or their respective affiliates for any out-of-pocket expenses incurred by it in connection with the performance of such services.

No compensation of any kind, including any finder’s fee, reimbursement, consulting fee or monies in respect of any payment of a loan, will be paid by XPDB to the Sponsor, officers and directors, or any affiliate of the Sponsor or officers, prior to, or in connection with any services rendered in order to effectuate, the consummation of an initial business combination (regardless of the type of transaction that it is). However, these individuals will be reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential

208

Table of Contents

target businesses and performing due diligence on suitable business combinations. XPDB does not have a policy that prohibits the Sponsor, executive officers or directors, or any of their respective affiliates, from negotiating for the reimbursement of out-of-pocket expenses by a target business. XPDB’s audit committee reviews on a quarterly basis all payments that were made to the Sponsor, officers, directors or our or any of their affiliates and will determine which expenses and the amount of expenses that will be reimbursed. There is no cap or ceiling on the reimbursement of out-of-pocket expenses incurred by such persons in connection with activities on XPDB’s behalf.

Post-Combination Company Advisory, Service and Consulting Fees

After XPDB’s initial business combination, members of its management team who remain with the Post-Combination Company may be paid consulting, management or other fees from the Post-Combination Company with any and all amounts being fully disclosed to XPDB’s stockholders, to the extent then known, in the proxy solicitation materials or tender offer documents, as applicable, furnished to its stockholders. It is unlikely the amount of such compensation will be known at the time of distribution of such proxy solicitation materials or tender offer documents, as applicable, as it will be up to the directors of the post-combination business to determine executive and director compensation.

Registration Rights

XPDB has entered into the Registration Rights Agreement with respect to the Private Placement Warrants, the warrants issuable upon conversion of working capital loans (if any) and the shares of Class A Common Stock issuable upon exercise of the foregoing and upon conversion of the Founder Shares, which is described under the section of this proxy statement/prospectus entitled “Description of Securities — Registration Rights.”

Policy for Approval of Related Party Transactions

The audit committee of the XPDB Board has adopted a charter providing for the review, approval and/or ratification of “related party transactions,” which are those transactions required to be disclosed pursuant to Item 404 of Regulation S-K as promulgated by the SEC, by the audit committee. At its meetings, the audit committee shall be provided with the details of each new, existing or proposed related party transaction, including the terms of the transaction, any contractual restrictions that XPDB has already committed to, the business purpose of the transaction and the benefits of the transaction to XPDB and to the relevant related party. Any member of the committee who has an interest in the related party transaction under review by the committee shall abstain from voting on the approval of the related party transaction, but may, if so requested by the chairman of the committee, participate in some or all of the committee’s discussions of the related party transaction. Upon completion of its review of the related party transaction, the committee may determine to permit or to prohibit the related party transaction.

The Post-Combination Company will adopt a formal written policy that will be effective upon the Closing providing that the Post-Combination Company’s officers, directors, nominees for election as directors, beneficial owners of more than 5% of any class or series of the Post-Combination Company’s capital stock, any member of the immediate family of any of the foregoing persons and any firm, corporation or other entity in which any of the foregoing persons is employed or is a general partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest in the Post-Combination Company, are not permitted to enter into a related party transaction with the Post-Combination Company without the approval of the nominating and corporate governance committee of the Post-Combination Company Board, subject to certain exceptions.

Indemnification of Directors and Officers

The Amended and Restated Bylaws will provide that the Post-Combination Company will be required to indemnify its directors and officers to the fullest extent permitted by the DGCL. In addition, the Proposed Charter will provide that the Post-Combination Company’s directors will not be liable for monetary damages for breach of fiduciary duty to the fullest extent permitted by the DGCL. There is no pending litigation or proceeding naming any of XPDB’s or Montana’s respective directors or officers to which indemnification is being sought, and neither XPDB or Montana, is aware of any pending or threatened litigation that may result in claims for indemnification by the Post-Combination Company with respect to any director or officer.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of
Power & Digital Infrastructure Acquisition II Corp.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Power & Digital Infrastructure Acquisition II Corp. (the “Company”) as of December 31, 2022 and 2021, the related statements of operations, changes in stockholders’ deficit and cash flows for the year ended December 31, 2022 and for the period from March 23, 2021 (inception) through December 31, 2021, 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, 2022 and 2021, and the results of its operations and its cash flows for the year ended December 31, 2022 and for the period from March 23, 2021 (inception) through December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

Explanatory Paragraph — Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1, Company’s liquidity needs, mandatory liquidation and subsequent dissolution raise 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 audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits 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 audits 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 audits 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 audits 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 audits provide a reasonable basis for our opinion.

NOTES TO FINANCIAL STATEMENTS

Note 1 — Description of Organization, Business Operations and Liquidity

Power & Digital Infrastructure Acquisition II Corp. (the “Company”) is a blank check company incorporated in Delaware on March 23, 2021. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies.

As of December 31, 2022, the Company had not commenced any operations. All activity for the period from March 23, 2021 (inception) through December 31, 2022 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), as 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 its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s sponsor is XPDI Sponsor II LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on December 9, 2021. On December 14, 2021, the Company consummated its Initial Public Offering of 28,750,000 units (the “Units” and, with respect to the Class A common stock included in the Units being offered, the “Public Shares”), which included the exercise of the underwriters’ option to purchase an additional 3,750,000 Units at the initial public offering price to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $287.5 million, and incurring offering costs of approximately $20.7 million, of which approximately $10.1 million was for deferred underwriting fees (see Note 5).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 11,125,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”), at a price of $1.00 per Private Placement Warrant to the Sponsor and certain funds and accounts managed by subsidiaries of BlackRock, Inc., an unrelated party (the “Anchor Investors”), generating proceeds of approximately $11.1 million (Note 4).

Upon the closing of the Initial Public Offering and the Private Placement, approximately $290.4 million ($10.10 per Unit) of the net proceeds of the sale of the Units in the Initial Public Offering and of the Private Placement Warrants in the Private Placement were placed in a trust account (“Trust Account”) located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. “government securities,” within the meaning of Section 2(a)(16) of the Investment Company Act 1940, as amended (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.

While the Company’s management has broad discretion with respect to the specific application of the cash held outside of the Trust Account, substantially all of the net proceeds from the Initial Public Offering and the sale of the Private Placement Warrants, which are placed in the Trust Account, are intended to be applied generally toward completing a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable by us on the income earned on the trust account) at the time of the agreement to enter into the initial Business Combination. However, the Company only intends to complete a Business Combination if the post-transaction company owns or acquires 50% or more of the issued and 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.

Note 1 — Description of Organization, Business Operations and Liquidity (cont.)

The Company will provide the holders (the “Public Stockholders”) of the Company’s Public Shares with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (initially at $10.10 per Public Share). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). 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 stockholder vote or tender offer in connection with the initial Business Combination and in connection with certain amendments to the Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”). These Public Shares were recorded at a redemption value and classified as temporary equity in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”). The Company will proceed with a Business Combination if a majority of the shares voted are voted in favor of the Business Combination. The Company will not redeem the Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001 immediately following the Business Combination.

If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation, conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem the Public Shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with a Business Combination, the initial stockholders (as defined below) agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the initial stockholders agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

The Amended and Restated Certificate of Incorporation provides that a Public Stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder 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% of the Public Shares, without the prior consent of the Company.

The Company will have until December 14, 2023 or such further extended date as determined by the Company’s board of directors in accordance with the Amended and Restated Certificate of Incorporation (the “Combination Period”), to complete the initial Business Combination. If the Company is unable to complete a Business Combination within the Combination Period, as it may be extended, or such later date as approved by holders of a majority of the voting power of the Company’s then outstanding shares of common stock that are voted at a meeting to extend such Combination Period, voting together as a single class, the Company will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than 10 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 (less up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable by us), divided by the number of then issued and outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions,

if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Company’s board of directors, liquidate and dissolve, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The holders of the Founder Shares (the “initial stockholders”) agreed not to propose an amendment to the Amended and Restated Certificate of Incorporation (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with its initial Business Combination or to redeem 100% of the Public Shares if the Company has not consummated an initial Business Combination within 18 months (or 21 months or 24 months, as applicable) from the closing of the Initial Public Offering or (B) with respect to any other provisions of the Amended and Restated Certificate of Incorporation relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

The initial stockholders and Anchor Investors agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the initial stockholders and Anchor Investors 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 agreed to waive their rights to the deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the 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 $10.10, or $10.20 or $10.30 per Public Share, as applicable, if the Company extends the period of time the Company will have to complete an initial Business Combination. In order to protect the amounts held in the Trust Account, the Sponsor agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement (a “Target”), reduce the amount of funds in the Trust Account to below (i) $10.10 per Public Share, or $10.20 or $10.30 per public share, as applicable, if the Company extends the period of time it will have to complete an initial Business Combination, or (ii) the lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the Trust assets, in each case net of interest which may be withdrawn to pay taxes, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to seek access to the Trust Account 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 all vendors, service providers (other than 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 and Capital Resources

As of December 31, 2022, the Company had approximately $1.3 million in cash and working capital of approximately $0.66 million (not taking into account approximately $875,000 in tax obligations that may be paid using investment income classified in the Trust Account).

the Note (as defined in Note 4). The Company fully repaid the Note on December 17, 2021. Subsequent to the consummation of the Initial Public Offering, the Company’s liquidity has been satisfied through the net proceeds from the consummation of the Initial Public Offering and the Private Placement held outside of the Trust Account.

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 under the Working Capital Loans (as defined and described in Note 4).

In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Presentation of Financial Statements — Going Concern,” management has determined that the liquidity needs, mandatory liquidation and subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern, which is considered to be one year from the issuance of these financial statements. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after June 14, 2023. The financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern. The Company intends to complete a Business Combination before the mandatory liquidation date, as it may be extended. Over this time period, the Company will be using the funds outside of the Trust Account for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

Risks and Uncertainties

Management is currently evaluating the impact of the COVID-19 pandemic on the Company and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a Target, the specific impact is not readily determinable as of the date of the financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 1 — Description of Organization, Business Operations and Liquidity (cont.)

Business Combination, extension vote or otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination, extension vote or otherwise will depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the Business Combination, extension or otherwise, (ii) the structure of a Business Combination, (iii) the nature and amount of any “PIPE” or other equity issuances in connection with a Business Combination (or otherwise issued not in connection with a Business Combination but issued within the same taxable year of a Business Combination) and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available on hand to complete a Business Combination and in the Company’s ability to complete a Business Combination.

Note 2 — Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of 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 independent registered public accounting firm 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 stockholder 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 an 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 and 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 that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

NOTES TO FINANCIAL STATEMENTS

Note 2 — Summary of Significant Accounting Policies (cont.)

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times, may exceed the Federal Depository Insurance Corporation coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

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 no cash equivalents as of December 31, 2022 and 2021.

Investments Held in Trust Account

The Company’s portfolio of investments is comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in income from investments held in 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.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the 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;

• 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.

Note 2 — Summary of Significant Accounting Policies (cont.)

Derivative Financial Instruments

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The warrants issued in the Initial Public Offering (“Public Warrants”) and the Private Placement Warrants are not precluded from equity classification, based on the guidance in ASC 480 and ASC 815. Equity-classified contracts are initially measured at fair value (or allocated value). Subsequent changes in fair value are not recognized as long as the contracts continue to be classified in equity.

Offering Costs Associated with the Initial Public Offering

Offering costs consisted of legal, accounting, underwriting fees and other costs incurred that were directly related to the Initial Public Offering. Upon completion of the Initial Public Offering, offering costs were allocated to the separable financial instruments issued in the Initial Public Offering on a relative fair value basis, compared to total proceeds received. Offering costs associated with the Class A common stock were charged to the carrying value of Class A common stock subject to possible redemption upon the completion of the Initial Public Offering. Offering costs associated with the Public Warrants and the Private Placement Warrants were recognized net in equity.

Class A Common Stock Subject to Possible Redemption

The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC 480. Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable shares of Class A common stock (including shares of Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. Shares of Class A common stock of the Company feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of December 31, 2022 and 2021, 28,750,000 shares of Class A common stock subject to possible redemption were presented as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheets.

Under ASC 480, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of the reporting period. This method would view the end of the reporting period as if it were also the redemption date of the security. Effective with the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit.

Income Taxes

The Company complies with the accounting and reporting requirements of FASB ASC Topic 740, “Income Taxes” (“ASC 740”), which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

POWER & DIGITAL INFRASTRUCTURE ACQUISITION II CORP.
NOTES TO FINANCIAL STATEMENTS

Note 2 — Summary of Significant Accounting Policies (cont.)

ASC 740 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. There were no unrecognized tax benefits as of December 31, 2022 and 2021. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of December 31, 2022 and 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

Net Income (Loss) per Common Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per common share is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period.

The calculation of diluted net income (loss) does not consider the effect of the Public Warrants and the Private Placement Warrants to purchase an aggregate of 25,500,000 Class A common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share for the year ended December 31, 2022 and for the period from March 23, 2021 (inception) through December 31, 2021. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value.

Recent Accounting Pronouncements

In August 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception, and it simplifies the diluted earnings per share calculation in certain areas. The Company adopted ASU 2020-06 on March 23, 2021 (inception) using a modified retrospective method for transition. Adoption of the ASU did not impact the Company’s financial position, results of operations or cash flows.

On December 14, 2021, the Company consummated its Initial Public Offering of 28,750,000 Units, which included the exercise of the underwriters’ option to purchase an additional 3,750,000 Over-Allotment Units at the initial public offering price, generating gross proceeds of $287.5 million, and incurring offering costs of approximately $20.7 million, of which approximately $10.1 million was for deferred underwriting fees.

Each Unit consists of one share of Class A common stock, and one-half of one redeemable warrant (each, a “Public Warrant”). Each Public Warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment (see Note 7).

Note 4 — Related Party Transactions

Founder Shares

On March 30, 2021, the Sponsor paid $25,000 to cover for certain offering costs on behalf of the Company in exchange for issuance of 5,750,000 shares of the Company’s Class B common stock, par value $0.0001 per share, (the “Founder Shares”). In November 2021, the Company effected a stock dividend of 1,437,500 shares of Class B common stock, resulting in there being an aggregate of 7,187,500 shares of Class B common stock outstanding. All shares and associated amounts have been retroactively restated to reflect the stock dividend. The initial stockholders agreed to forfeit up to an aggregate of 937,500 Founder Shares, so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding shares after the Initial Public Offering. The underwriters exercised their over-allotment option in full on December 14, 2021; thus, these 937,500 Founder Shares were no longer subject to forfeiture.

In July 2021, the Sponsor transferred 30,000 Founder Shares to each of the four independent director nominees, a total of 120,000 Founder Shares. In November 2021, the Sponsor repurchased 30,000 shares of Class B common stock from a former independent director nominee at a price of $120. The transfer of the Founder Shares is in the scope of FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The Founders Shares were granted subject to a performance condition (i.e., the occurrence of a Business Combination). Compensation expense related to the Founders Shares is recognized only when the performance condition is probable of occurrence under the applicable accounting literature in this circumstance. As of December 31, 2022 and 2021, the Company determined that a Business Combination is not considered probable, and, therefore, no stock-based compensation expense has been recognized. As of December 31, 2022 and 2021, stock-based compensation of approximately $516,000 will be recognized at the date a Business Combination is considered probable (i.e., upon completion of a Business Combination).

In exchange for the Anchor Investors participating in the Initial Public Offering and the Private Placement, the Company agreed sell 1,078,125 Founder Shares to the Anchor Investors, and the Anchor Investors agreed to purchase from the Company on the date of the initial Business Combination such Founder Shares. The Sponsor also agreed that in the event of such purchase by the Anchor Investors, the Sponsor will forfeit to the Company for no consideration a number of Founder Shares equal to the number of Founder Shares purchased by the Anchor Investors. Further, the Anchor Investors agreed that, if they do not own an aggregate of at least certain amount of Public Shares (such amount, the “Anchor Threshold”) at the time of any stockholder vote with respect to an initial Business Combination or the business day immediately prior to the completion of the initial Business Combination, the number of Founder Shares to be purchased by such Anchor Investors from the Company will be reduced pro rata by a fraction, the numerator of which will equal the Anchor Threshold less the number of Public Shares held by such Anchor Investors after giving effect to any redemptions of the Public Shares by such Anchor Investors and their affiliates, and the denominator of which will equal the Anchor Threshold; provided, however, in no event will such pro rata reduction in the number of Founder Shares

to be purchased by the Anchor Investors reduce the number of Founder Shares to be purchased by more than 75%. The Company determined that the excess of the fair value of the Founder Shares to be acquired by the Anchor Investors upon the closing of the initial Business Combination (in which case the Sponsor also agreed to forfeit to the Company for no consideration a number of Founder Shares equal to the number of Founder Shares purchased by the Anchor Investors) should be recognized as an offering cost by the Company in accordance with SEC Staff Accounting Bulletin (“SAB”) Topic 5A, “Expenses of Offerings.” The Company estimated the aggregate fair value of the Sponsor’s agreement to sell Founder Shares to the Anchor Investors to be approximately $4.7 million using a Monte Carlo simulation. Accordingly, the additional offering cost is allocated to the separable financial instruments issued in the Initial Public Offering on a relative fair value basis, compared to total proceeds received. The allocated portion of the additional offering cost associated with the Class A common stock was charged to the carrying value of Class A common stock subject to possible redemption upon the completion of the Initial Public Offering.

The initial stockholders and the Anchor Investors agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination; and (B) subsequent to the initial Business Combination (x) if the last reported sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, 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 (y) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of common stock for cash, securities or other property. Any permitted transferees would be subject to the same restrictions and other agreements of the initial stockholders and the Anchor Investors with respect to any Founder Shares.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 11,125,000 Private Placement Warrants, at a price of $1.00 per Private Placement Warrant to the Sponsor and the Anchor Investors, generating proceeds of approximately $11.1 million.

Each Private Placement Warrant is exercisable for one whole share of Class A common stock at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants was added to the 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 Private Placement Warrants will expire worthless.

The purchasers of the Private Placement Warrants agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants (except to permitted transferees) until 30 days after the completion of the initial Business Combination.

Related Party Loans

On March 30, 2021, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (as amended and restated on July 1, 2021, the “Note”). This loan was non-interest bearing and payable upon the completion of the Initial Public Offering. As of December 14, 2021, the Company borrowed approximately $115,000 under the Note. The Company fully repaid the Note on December 17, 2021.

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 completion of a Business Combination or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. 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, 2022 and 2021, the Company had no borrowings under the Working Capital Loans.

Administrative Services Agreement

Commencing on December 9, 2021 through the earlier of consummation of the initial Business Combination and the Company’s liquidation, the Company agreed to pay affiliates of the Sponsor a total of $20,000 per month for office space, administrative and support services. During the year ended December 31, 2022 and the period from March 23, 2021 (inception) through December 31, 2021 the Company incurred $240,000 and $20,000 of such fees, respectively, which are recognized in general and administrative expenses — related party, in the accompanying statements of operations. As of December 31, 2022 and 2021, the Company had $260,000 and $20,000, respectively, payable in connection with such agreement, included as accrued expenses in the accompanying balance sheets.

Note 5 — Commitments and Contingencies

Registration Rights

The holders of Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans, if any (and any shares of common stock issuable upon the exercise of the Private Placement Warrants or warrants issued upon conversion of the Working Capital Loans and upon conversion of the Founder Shares), were entitled to registration rights pursuant to a registration rights agreement to be signed prior to the consummation of the Initial Public Offering. These holders are entitled to certain demand and “piggyback” registration rights. 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 were entitled to an underwriting discount of $0.20 per Unit on all Units sold in the Initial Public Offering, except for the Units purchased by the Anchor Investors, or approximately $5.3 million in the aggregate, paid upon the closing of the Initial Public Offering.

An additional fee of $0.35 per Unit, or approximately $10.1 million in the aggregate, will be payable to the underwriters for deferred underwriting commissions. The deferred fee will 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.

Note 6 — Class A Common Stock Subject to Possible Redemption

The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of future events. The Company is authorized to issue 500,000,000 shares of Class A common stock with a par value of $0.0001 per share. Holders of the Company’s Class A common stock are entitled to one vote for each share. As of December 31, 2022 and 2021, there were 28,750,000 shares of Class A common stock outstanding, which were all subject to possible redemption and classified outside of permanent equity in the accompanying balance sheets.

Preferred Stock — The Company is authorized to issue 1,000,000 shares of preferred stock, par value $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of December 31, 2022 and 2021, there were no shares of preferred stock issued or outstanding.

Class A Common Stock — The Company is authorized to issue 500,000,000 shares of Class A common stock with a par value of $0.0001 per share. As of December 31, 2022 and 2021, there were 28,750,000 shares of Class A common stock issued and outstanding, all of which were subject to possible redemption and were classified outside of permanent equity in the accompanying balance sheets (see Note 6).

Class B Common Stock — The Company is authorized to issue 50,000,000 shares of Class B common stock with a par value of $0.0001 per share. As of December 31, 2022 and 2021, there were 7,187,500 shares of Class B common stock issued and outstanding. Of the 7,187,500 shares of Class B common stock outstanding, up to 937,500 shares of Class B common stock were subject to forfeiture. The over-allotment option was exercised in full, therefore shares of Class B common stock were no longer subject to forfeiture.

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders and vote together as a single class, except as required by law; provided, that, prior to the Company’s initial Business Combination, holders of the Class B common stock will have the right to appoint all of the Company’s directors and remove members of the board of directors for any reason, and holders of the Class A common stock will not be entitled to vote on the appointment of directors during such time.

The Class B common stock will automatically convert into Class A common stock at the time of the initial Business Combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts issued in the Initial Public Offering and related to the closing of the initial Business Combination, the ratio at which the shares of Class B common stock will convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the issued and outstanding shares of the Class B common stock agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of all shares of common stock issued and outstanding upon the completion of the Initial Public Offering plus all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with the initial Business Combination, excluding any shares or equity-linked securities issued, or to be issued, to any seller in the initial Business Combination.

Warrants — As of December 31, 2022 and 2021, the Company has 14,375,000 and 11,125,000 Public Warrants and Private Placement Warrants outstanding, respectively. Public Warrants may only be exercised for a whole number of shares. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). The Company agreed that as soon as practicable, but in no event later than 20 business days after the closing of its initial Business Combination, the Company will use its commercially reasonable efforts to file with the SEC and have an effective registration statement covering the shares of Class A common stock issuable upon exercise of the warrants and will use its commercially reasonable efforts to cause the same to become effective within 60 business days after the closing of the Company’s initial Business Combination and to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed. If the shares issuable upon exercise of the warrants are not registered under the Securities Act in accordance with the above requirements, the Company will be required to permit holders to exercise their warrants on a cashless basis. However, no warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue any shares to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption from registration is available. Notwithstanding the above, if the Company’s shares of Class A common stock are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a cashless basis in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, it will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

The warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation. In addition, if (x) the Company issues additional shares of Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per share of Class A common stock (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the completion of the initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Class A common stock during the 20 trading day period starting on the trading day prior to the day on which the Company completes the initial Business Combination (such price, the “Market Value”) is below $9.20 per share, then the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger prices described below under “Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00” to be equal to 180% of the higher of the Market Value and the Newly Issued Price described below under “Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00” will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

The Private Placement Warrants will be non-redeemable and will be exercisable on a cashless basis at the option of the holder.

Note 7 — Stockholders’ Deficit (cont.)

Redemption of Public Warrants when the price per share of Class A common stock equals or exceeds $18.00:

Once the warrants become exercisable, the Company may call the outstanding warrants for redemption (except as described herein with respect to the Private Placement Warrants):

• in whole and not in part;

• at a price of $0.01 per warrant;

• upon a minimum of 30 days’ prior written notice of redemption to each warrant holder; and

• if, and only if, the last reported sale price of Class A common stock for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders (the “Reference Value”) equals or exceeds $18.00 per share (as adjusted).

Unless the Company has elected to require Public Warrant holders to exercise such warrants on a cashless basis, the Company will not redeem the Public Warrants as described above unless a registration statement under the Securities Act covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants is then effective and a current prospectus relating to those shares of Class A common stock is available throughout the 30-day redemption period. If and when the Public Warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

Note 8 — Income Taxes

The Company’s taxable income primarily consists of interest income on the Trust Account. The Company’s general and administrative expenses are generally considered start-up costs and are not currently deductible. There was no income tax expense for the period from March 23, 2021 (inception) through December 31, 2021.

Note 8 — Income Taxes (cont.)

As of December 31, 2022 and 2021, the Company had $0 and $151,300, respectively, of U.S. federal net operating loss carryovers available to offset future taxable income which do not expire.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax assets, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. At December 31, 2022 and 2021, the valuation allowance was $319,341 and $114,287, respectively.

A reconciliation of the statutory federal income tax rate (benefit) to the Company’s effective tax rate (benefit) is as follows:

	December 31, 2022		December 31, 2021
Statutory federal income tax rate	21.0	%	21.0	%
Change in valuation allowance	7.2	%	(21.0	)%
Income Taxes Benefit	28.2	%	0.0	%

Note 9 — Fair Value Measurements

The following table presents information about the Company’s assets that are measured at fair value on a recurring basis as of December 31, 2022 and 2021 and indicates the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value.

Description	Level 1		Level 2	Level 3

December 31, 2021 – Assets:
Investments held in Trust Account	$	290,375,895	—		—

Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. There were no transfers between levels for the period from March 23, 2021 (inception) through December 31, 2022.

Level 1 assets include investments in money market funds or U.S. Treasury securities. The Company uses inputs such as actual trade data, benchmark yields, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments.

Note 10 — Subsequent Events

Management has evaluated subsequent events and transactions that occurred after the balance sheet date through the date the financial statements are available for issuance. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements.

NOTE 1 — DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND LIQUIDITY

As of June 30, 2023, the Company had not commenced any operations. All activity for the period from March 23, 2021 (inception) through June 30, 2023 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), as 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 its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s sponsor is XPDI Sponsor II LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on December 9, 2021. On December 14, 2021, the Company consummated its Initial Public Offering of 28,750,000 units (the “Units” and, with respect to the Class A common stock, $0.0001 par value per share (“Class A common stock”) included in the Units being offered, the “Public Shares”), which included the exercise of the underwriters’ option to purchase an additional 3,750,000 Units at the initial public offering price to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $287.5 million, and incurring offering costs of approximately $20.7 million, of which approximately $10.1 million was for deferred underwriting fees (see Note 5).

Public Shares for a pro rata portion of the amount then held in the Trust Account (initially at $10.10 per Public Share). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). 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 stockholder vote or tender offer in connection with the initial Business Combination and in connection with certain amendments to the Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”). These Public Shares were recorded at a redemption value and classified as temporary equity in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”). The Company will proceed with a Business Combination if a majority of the shares voted are voted in favor of the Business Combination.

On May 5, 2023, the Company filed a preliminary proxy statement (the “Proxy Statement”) for the solicitation of proxies in connection with the special meeting in lieu of Annual Meeting of the Company’s stockholders (the “Special Meeting”) to consider and vote on, among other proposals, the extension of the date by which the Company must consummate an initial Business Combination from June 14, 2023 (the “Current Outside Date”) to December 14, 2023 (such date, the “Extended Date”), and to allow the Company, without another stockholder vote, by resolution of the Company’s board of directors to elect to further extend the Extended Date in one-month increments up to three additional times, or a total of up to nine months after the Current Outside Date, until March 14, 2024 (the “Combination Period”), unless the closing of a Business Combination shall have occurred prior thereto or such earlier date as determined by our board of directors to be in the best interests of the Company (such proposal, the “Extension Amendment Proposal”), and the amendment of the Company’s amended and restated certificate of incorporation to remove the limitation that the Company may not redeem public shares to the extent that such redemption would result in the Company having net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Securities Exchange Act of 1934, as amended (or any successor rule) of less than $5,000,001 (such proposal, the “Redemption Limitation Amendment Proposal”).

At the Special Meeting on June 9, 2023, the Company’s stockholders approved the Extension Amendment Proposal and the Redemption Limitation Amendment Proposal. In connection with the stockholders’ vote at the Special Meeting, the stockholders elected to redeem 18,141,822 shares of Class A common stock at a redemption price of approximately $10.37 per share, for an aggregate redemption amount of approximately $188,132,132 (the “Redemption”). After the satisfaction of the Redemption, the balance in the Trust Account as of June 30, 2023 was approximately $110,058,882. Upon completion of the Redemption, 10,608,178 shares of Class A common stock and 7,187,500 shares of Class B common stock remain issued and outstanding.

the lesser of (i) $0.03 multiplied by the number of shares of Class A common stock then outstanding and not redeemed in connection with the Special Meeting and (ii) $300,000. As a result, $300,000 was deposited in the Trust Account by the Company on June 15, 2023, July 10, 2023 and August 10, 2023. On September 8, 2023, $300,000 was deposited in the Trust Account by the Sponsor.

If the Company is unable to complete a Business Combination within the Combination Period, as it may be extended, or such later date as approved by holders of a majority of the voting power of the Company’s then outstanding shares of common stock that are voted at a meeting to extend such Combination Period, voting together as a single class, the Company will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than 10 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 (less up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable by us), divided by the number of then issued and outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Company’s board of directors, liquidate and dissolve, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The holders of the Founder Shares (the “initial stockholders”) agreed not to propose an amendment to the Amended and Restated Certificate of Incorporation (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with its 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 provisions of the Amended and Restated Certificate of Incorporation relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

Merger Agreement

On June 5, 2023, the Company and XPDB Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“Merger Sub”), entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time in accordance with its terms, the “Merger Agreement”) with Montana Technologies LLC, a Delaware limited liability company (“Montana”), pursuant to which Merger Sub will merge with and into Montana, with Montana surviving the Merger as a wholly owned subsidiary of the Company (the “Merger” and, along with the transactions contemplated in the Merger Agreement, the “Proposed Transactions”). Following the closing of the Proposed Transactions (the “Closing”), the Company will be renamed “Montana Technologies Corporation” (the “Combined Company”).

As part of the Transactions, equity holders of Montana will receive aggregate consideration of approximately $421.9 million (subject to adjustment as described in the Merger Agreement), payable (i) in the case of Class B and holders of Class C common units of Montana (after giving effect to the conversion of all outstanding preferred units of Montana into Class B common units, which conversion will occur prior to the Closing), newly issued shares of Class A common stock, par value $0.0001 per share, of the Combined Company (“Combined Company Class A common stock”), with a value ascribed to each share of Combined Company Class A common stock of $10.00, (ii) in the case of holders of Class A common units of Montana, newly issued shares of Class B common stock, par value $0.0001 per share, of the Combined Company (“Combined Company Class B common stock”), which Combined Company Class B common stock will have a number of votes per share such that the equity holders of Montana as of immediately prior to the Closing will collectively own at least 80% of the voting power of all classes of stock of the Combined Company entitled to vote immediately following the Closing and (iii) in the case of Montana’s option holders and warrant holders, options and warrants of the Combined Company, respectively, having substantially similar terms to the applicable options and warrants of Montana.

Montana’s equity holders (other than warrant holders) will also have the opportunity to receive additional equity consideration (in each case, in accordance with their respective pro rata share) in the form of shares of Combined Company Class A common stock, with a $10.00 value ascribed to each share (the “Earnout Shares”), only upon full completion of construction and operational viability (including all permitting, regulatory approvals and necessary or useful inspections) of new production capacity of Montana’s key components or assemblies based solely on demand from bona fide customer commitments evidenced by binding contracts (or in the discretion of a majority of the independent members of the board of directors of the Combined Company, a non-binding letter of intent or indication of interest or similar writing that is substantially likely to become a binding contract) with a known price or pricing formula that exceeds a level of production capacity that is expected to generate Annualized EBITDA of more than $150,000,000 (the “Threshold Annualized EBITDA”), which shall be determined by a majority of the independent members of the board of directors of the Combined Company in its sole discretion, equal to (i) the ratio of (x) (1) the Annualized EBITDA that is expected from such new production capacity (the “Expected Annualized EBITDA”) less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous new production capacities for which previous earnouts were achieved, divided by (y) $150,000,000 multiplied by (ii) $200,000,000, provided that the aggregate Expected Annualized EBITDA may not exceed $300,000,000. The maximum value of the Earnout Shares will be capped at $200 million and the ability to receive Earnout Shares will expire on the fifth anniversary of the Closing. A majority of the independent members of the board of directors of the Combined Company then serving will have sole discretion in determining, among other things, the achievement of the applicable milestones, the calculations of payments of Earnout Shares to the applicable Montana equity holders, the dates on which construction and operational viability of new production capacity is deemed completed and whether to consent to a transfer of the applicable Montana equity holder’s right to receive Earnout Shares. Earnout Shares issuable in respect of Montana options outstanding as of immediately prior to the effective time of the Merger may be issued to the holder of such Montana option only if such holder continues to provide services (whether as an employee, director or individual independent contractor) to the Combined Company or one of its subsidiaries through the date on which such Earnout Shares are issued, as determined by a majority of the independent members of the Combined Company Board.

Sponsor Support Agreement

In connection with the execution of the Merger Agreement, the Sponsor entered into a sponsor support agreement (the “Sponsor Support Agreement”) with the Company, Montana and other holders of the Company’s Class B common stock, $0.0001 par value per share (“Class B common stock”).

The Sponsor Support Agreement provides that as of immediately prior to (but subject to) the Closing, 1,380,736 (or 20%) of the Class B common stock held by the Sponsor as of the Closing will be subject to certain time and performance-based vesting provisions.

The Sponsor Support Agreement will terminate on the earlier of (i) the date the Proposed Transactions become effective or (ii) the termination of the Merger Agreement in accordance with its terms.

Liquidity, Capital Resources and Going Concern

As of June 30, 2023, the Company had approximately $0.5 million in cash and working capital deficit of approximately $5.6 million (not taking into account approximately $0.2 million tax obligations that may be paid using investment income classified in the Trust Account).

The Company’s liquidity needs prior to the consummation of the Initial Public Offering were satisfied through the payment of $25,000 from the Sponsor to cover certain offering costs on behalf of the Company in exchange for issuance of Founder Shares (as defined in Note 4) and a loan from a related party of approximately $115,000 under the Note (as defined in Note 4). The Company fully repaid the Note on December 17, 2021. Subsequent to the consummation of the Initial Public Offering, the Company’s liquidity has been satisfied through the net proceeds from the consummation of the Initial Public Offering and the Private Placement held outside of the Trust Account.

In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Presentation of Financial Statements — Going Concern,” management has determined that the liquidity needs, mandatory liquidation and subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern, which is considered to be one year from the issuance of these financial statements. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after December 14, 2023. The financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern. The Company intends to complete a Business Combination before the mandatory liquidation date, as it may be extended. Over this time period, the Company will be using the funds outside of the Trust Account for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

NOTE 2 — BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying condensed consolidated financial statements of the Company have been prepared in U.S. dollars in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and Article 8 of Regulation S-X. Accordingly, certain disclosures included in the annual financial statements have been condensed or omitted from these financial statements as they are not required for interim financial statements. In the opinion of management, all adjustments (consisting of normal accruals) considered for a fair presentation have been included. Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or any future period.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on April 17, 2023, which contains the audited financial statements and notes thereto. The financial information as of December 31, 2022, is derived from the audited financial statements presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on April 17, 2023.

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, XPDB Merger Sub, LLC. There has been no intercompany activity since inception.

Emerging Growth Company

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 an 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 and 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 condensed financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Cash and Cash Equivalents

Investments Held in Trust Account

The Company’s portfolio of investments is comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the condensed consolidated balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in income from investments held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the condensed consolidated balance sheets, primarily due to their short-term nature.

Offering Costs Associated with the Initial Public Offering

Class A Common Stock Subject to Possible Redemption

The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC 480. Shares of Class A common stock subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable shares of Class A common stock (including shares of Class A common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, shares of Class A common stock are classified as stockholders’ equity. Shares of Class A common stock of the Company feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of June 30, 2023 and December 31, 2022, 10,608,178 and 28,750,000, respectively, shares of Class A common stock subject to possible redemption were presented as temporary equity, outside of the stockholders’ equity section of the Company’s condensed consolidated balance sheets.

In connection with the stockholders’ vote at the Special Meeting, the stockholders elected to redeem 18,141,822 shares of Class A common stock at a redemption price of approximately $10.37 per share, for an aggregate redemption amount of approximately $188,132,132. After the satisfaction of the Redemption, the balance in the Trust Account as of June 30, 2023 was approximately $110,058,882. Upon completion of the Redemption, 10,608,178 shares of Class A common stock and 7,187,500 shares of Class B common stock remain issued and outstanding.

Income Taxes

FASB ASC Topic 740 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. There were no unrecognized tax benefits as of June 30, 2023 and December 31, 2022. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of June 30, 2023 and December 31, 2022. The Company is currently not aware of

any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. The Company’s effective tax rate was 128.10% and 189.87% for the three months ended June 30, 2023 and 2022, respectively, 49.30% and 6.93% for the six months ended June 30, 2023 and 2022, respectively. The effective tax rate differs from the statutory tax rate of 21% for the three and six months ended June 30, 2023 due to the increase in the valuation allowance.

Net (Loss) Income per Common Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net (loss) income per common share is calculated by dividing the net (loss) income by the weighted average shares of common stock outstanding for the respective period.

The calculation of diluted net (loss) income does not consider the effect of the Public Warrants and the Private Placement Warrants to purchase an aggregate of 25,500,000 Class A common stock in the calculation of diluted (loss) income per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net (loss) income per share is the same as basic net (loss) income per share for the three and six months ended June 30, 2023 and 2022. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.

NOTE 3 — INITIAL PUBLIC OFFERING

Each Unit consists of one share of Class A common stock, and one-half of one redeemable warrant. Each Public Warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment (see Note 7).

NOTE 4 — RELATED PARTY TRANSACTIONS

Founder Shares

In July 2021, the Sponsor transferred 30,000 Founder Shares to each of the four independent director nominees, a total of 120,000 Founder Shares. In November 2021, the Sponsor repurchased 30,000 shares of Class B common stock from a former independent director nominee at a price of $120. The transfer of the Founder Shares is in the scope of FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The Founders Shares were granted subject to a performance condition (i.e., the occurrence of a Business Combination). Compensation expense related to the Founders Shares is recognized only when the performance condition is probable of occurrence under the applicable accounting literature in this circumstance. As of June 30, 2023 and December 31, 2022, the Company determined that a Business Combination is not considered probable, and, therefore, no stock-based compensation expense has been recognized. As of June 30, 2023 and December 31, 2022, stock-based compensation of approximately $516,000 will be recognized at the date a Business Combination is considered probable (i.e., upon completion of a Business Combination).

In exchange for the Anchor Investors participating in the Initial Public Offering and the Private Placement, the Company agreed to sell 1,078,125 Founder Shares to the Anchor Investors, and the Anchor Investors agreed to purchase from the Company on the date of the initial Business Combination such Founder Shares. The Sponsor also agreed that in the event of such purchase by the Anchor Investors, the Sponsor will forfeit to the Company for no consideration a number of Founder Shares equal to the number of Founder Shares purchased by the Anchor Investors. Further, the Anchor Investors agreed that, if they do not own an aggregate of at least certain amount of Public Shares (such amount, the “Anchor Threshold”) at the time of any stockholder vote with respect to an initial Business Combination or the business day immediately prior to the completion of the initial Business Combination, the number of Founder Shares to be purchased by such Anchor Investors from the Company will be reduced pro rata by a fraction, the numerator of which will equal the Anchor Threshold less the number of Public Shares held by such Anchor Investors after giving effect to any redemptions of the Public Shares by such Anchor Investors and their affiliates, and the denominator of which will equal the Anchor Threshold; provided, however, in no event will such pro rata reduction in the number of Founder Shares to be purchased by the Anchor Investors reduce the number of Founder Shares to be purchased by more than 75%. The Company determined that the excess of the fair value of the Founder Shares to be acquired by the Anchor Investors upon the closing of the initial Business Combination (in which case the Sponsor also agreed to forfeit to the Company for no consideration a number of Founder Shares equal to the number of Founder Shares purchased by the Anchor Investors) should be recognized as an offering cost by the Company in accordance with SEC Staff Accounting Bulletin (“SAB”) Topic 5A, “Expenses of Offerings.” The Company estimated the aggregate fair value of the Sponsor’s agreement to sell Founder Shares to the Anchor Investors to be approximately $4.7 million using a Monte Carlo simulation. Accordingly, the additional offering cost is allocated to the separable financial instruments issued in the Initial Public Offering on a relative fair value basis, compared to total proceeds received. The allocated portion of the additional offering cost associated with the Class A common stock was charged to the carrying value of Class A common stock subject to possible redemption upon the completion of the Initial Public Offering.

NOTE 4 — RELATED PARTY TRANSACTIONS (cont.)

stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of common stock for cash, securities or other property. Any permitted transferees would be subject to the same restrictions and other agreements of the initial stockholders and the Anchor Investors with respect to any Founder Shares.

Private Placement Warrants

Related Party Loans

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors 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 completion of a Business Combination or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. 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 June 30, 2023 and December 31, 2022, the Company had no borrowings under the Working Capital Loans.

Administrative Services Agreement

Commencing on December 9, 2021 through the earlier of consummation of the initial Business Combination and the Company’s liquidation, the Company agreed to pay affiliates of the Sponsor a total of $20,000 per month for office space, administrative and support services. During the three and six months ended June 30, 2023, the Company incurred $60,000 and $120,000 of such fees, respectively, which are recognized in general and administrative expenses — related party, in the accompanying condensed consolidated statements of operations. During the three and six months ended June 30, 2022, the Company incurred $60,000 and $120,000 of such fees, respectively, which are recognized in general and administrative expenses — related party, in the accompanying condensed consolidated statements of operations. As of June 30, 2023 and December 31, 2022, the Company had $380,000 and $260,000, respectively, payable in connection with such agreement, included as accrued expenses in the accompanying condensed consolidated balance sheets.

Registration Rights

Underwriting Agreement

An additional fee of $0.35 per Unit, or approximately $10.1 million in the aggregate will be payable to the underwriters for deferred underwriting commissions. The deferred fee will 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 June 20, 2023, BofA Securities, Inc. waived its entitlement to the payment of any deferred discount to be paid under the terms of underwriting agreement. As a result, the reduction in deferred fees was allocated on a pro rata basis between additional paid-in capital and other income based upon the original amount of the deferred underwriting fees allocation to the liability-classified instruments in the initial public offering. Therefore, the deferred underwriting fee was reduced by $4,025,000, of which $205,275 is reflected in the condensed consolidated statement of operations as other income and $3,819,725 is charged to additional paid-in capital in the statement of stockholders’ deficit. As a result of the waiver, the outstanding deferred underwriting fee payable was reduced to approximately $6.0 million.

Inflation Reduction Act of 2022

On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury (the “Treasury”) has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax. Any share redemption or other share repurchase that occurs after December 31, 2022, in connection with a Business Combination, extension vote or otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination, extension vote or otherwise will depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the Business Combination, extension or otherwise, (ii) the structure of a Business Combination, (iii) the nature and amount of any “PIPE” or other equity issuances in connection with a Business Combination (or otherwise issued not in connection with a Business Combination but issued within the same taxable year of a Business Combination) and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available on hand to complete a Business Combination and in the Company’s ability to complete a Business Combination.

NOTE 5 — COMMITMENTS AND CONTINGENCIES (cont.)

On June 9, 2023, the Company’s stockholders redeemed 18,141,822 shares of Class A shares of common stock for a total of $188,132,132. The Company evaluated the classification and accounting of the stock redemption under ASC 450, “Contingencies”. ASC 450 states that when a loss contingency exists the likelihood that the future event(s) will confirm the loss or impairment of an asset or the incurrence of a liability can range from probable to remote. A contingent liability must be reviewed at each reporting period to determine appropriate treatment. The Company evaluated the current status and probability of completing a Business Combination as of June 30, 2023 and concluded that it is probable that a contingent liability should be recorded. As of June 30, 2023, the Company recorded $1,881,321 of excise tax liability calculated as 1% of shares redeemed on June 9, 2023.

Class B Common Stock — The Company is authorized to issue 50,000,000 shares of Class B common stock with a par value of $0.0001 per share. As of June 30, 2023 and December 31, 2022, there were 7,187,500 shares of Class B common stock issued and outstanding.

Warrants — As of June 30, 2023 and December 31, 2022, the Company has 14,375,000 and 11,125,000 Public Warrants and Private Placement Warrants outstanding, respectively. Public Warrants may only be exercised for a whole number of shares. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). The Company agreed that as soon as practicable, but in no event later than 20 business days after the closing of its initial Business Combination, the Company will use its commercially reasonable efforts to file with the SEC and have an effective registration statement covering the shares of Class A common stock issuable upon exercise of the warrants and will use its commercially reasonable efforts to cause the same to become effective within 60 business days after the closing of the Company’s initial Business Combination and to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed. If the shares issuable upon exercise of the warrants are not registered under the Securities Act in accordance with the above requirements, the Company will be required to permit holders to exercise their warrants on a cashless basis. However, no warrant will be exercisable for cash or on a cashless basis, and the Company will not be obligated to issue any shares to holders seeking to exercise their warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption from registration is available. Notwithstanding the above, if the Company’s shares of Class A common stock are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a cashless basis in accordance with Section 3(a)(9) of the

MONTANA TECHNOLOGIES LLC
NOTES TO THE FINANCIAL STATEMENTS

Note 1 — ORGANIZATION AND BUSINESS OPERATIONS

Montana Technologies LLC (the “Company”) was established in 2018. The Company was established to pursue the development and expected commercialization of various technological innovations, and may engage in any activity or purpose permitted for a limited liability company organized in Delaware. The Company has created a transformational technology that provides significant energy efficiency gains in air conditioning and comfort cooling applications, as well as a potential source of potable water, all through its proprietary “AirJoule” unit.

Note 2 — LIQUIDITY AND GOING CONCERN

Historically, the Company’s primary sources of liquidity have been cash flows from contributions from founders or other investors. The Company reported operating losses for the years ended December 31, 2022 and 2021 and negative cash flows from operations of $2.8 million and $1.9 million for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022, the Company had an aggregate cash balance of $5.2 million, a net working capital of $5.1 million, and accumulated deficit of $5.8 million.

The Company’s future capital requirements will depend on many factors, including the Company’s timing and extent of its research and development efforts, building of facilities, and establishment of a sales and marketing team. In order to finance these opportunities, the Company will need to raise additional financing. While there can be no assurances, the Company intends to raise such capital through issuances of additional equity raises as well as debt securities in the capital markets if necessary. If additional financing is required from outside sources, the Company may not be able to raise such capital on terms acceptable to the Company or at all. If the Company is unable to raise additional capital when desired, the Company’s business, results of operations and financial condition would be materially and adversely affected.

As a result of the above, in connection with the Company’s assessment of going concern considerations in accordance with the 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,” the Company’s management has determined that its liquidity condition raises substantial doubt about its ability to continue as a going concern through twelve months from the date these consolidated financial statements are available to be issued. These consolidated financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

Note 3 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), expressed in U.S. dollars. The accompanying financial statements reflect all adjustments including normal recurring adjustments, which, in the opinion of the Company’s management, are necessary to present fairly the financial position, results of operations, and cash flows for the periods presented in accordance with GAAP. References to GAAP issued by the FASB in these accompanying notes to the financial statements are to the FASB Accounting Standards Codification (“ASC”). The financial statements have been prepared assuming the Company will continue as a going concern.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Some of the more significant estimates include estimates of amortization and depreciation and estimates relating to leases. Due to the uncertainty involved in making estimates, actual results could differ from those estimates which could have a material effect on the financial condition and results of operations in future periods.

Note 3 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

Cash and Concentration of Credit Risk

The Company considers all highly liquid investments with a maturity of 90 days or less at the time of purchase to be cash equivalents. The carrying values of cash and cash equivalents approximate their fair values due to the short-term nature of these instruments. As of December 31, 2022 and 2021, there were no cash equivalents. The Company maintains cash balances at financial institutions that may exceed the Federal Deposit Insurance Corporation’s insurance limits. The amounts over these insured limits as of December 31, 2022 and 2021 was $4,961,486 and $2,838,080, respectively. The Company mitigates this concentration of credit risk by monitoring the credit worthiness of the financial institutions. No losses have been incurred to date on any deposits.

Property and Equipment

Property and equipment is carried at cost less accumulated depreciation and includes expenditures that substantially increase the useful lives of existing property and equipment. Maintenance, repairs and minor renovations are charged to expense as incurred. When property and equipment is retired or otherwise disposed of, the related costs and accumulated depreciation are removed from their respective accounts, and any difference between the sale proceeds and the carrying amount of the asset is recognized as a gain or loss on disposal in the combined consolidated statements of income.

Depreciation is computed using the straight-line method over the estimated useful lives of the various classes of depreciable assets. The lives used in computing depreciation for significant asset classes are as follow:

		Estimated useful lives
Machinery and Equipment		3 years
Vehicles		3 years

The estimated useful lives and depreciation methods are reviewed at each year-end, with the effect of any changes in estimates accounted for prospectively. All depreciation expenses are included with depreciation and amortization in the statements of operations.

Long-Lived Asset Impairment (Excluding Intangibles)

The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value, and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value. No impairment loss was recognized during the year ended December 31, 2022. No impairment charges were recorded for the years ended December 31, 2022 and 2021.

Intangible Assets Subject to Amortization

Intangible assets include tradename, customer lists and non-compete agreements. Amounts are subject to amortization on a straight-line basis over the estimated period of benefit and to annual impairment consideration. Costs incurred to renew or extend the term of a recognized intangible asset, such as the acquired trademark, are capitalized as part of the intangible and amortized over its revised estimated useful life.

Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of the intangible assets may not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used or any other significant adverse change that would indicate that the carrying amount of an asset or group of assets may not be recoverable. The Company evaluates the recoverability of intangible assets by comparing their carrying amounts to future net undiscounted cash flows expected to be generated by the

intangible assets. If such intangible assets are considered to be impaired, the recognized impairment is measured as the amount by which the carrying amount of the intangible assets exceeds the fair value of the assets. The Company determines fair value based on discounted cash flows using a discount rate commensurate with the risk inherent in the Company’s current business model for the specific intangible asset being valued. As of December 31, 2022 and 2021, the Company does not have any intangible assets subject to amortization. An impairment loss of $54,901 was recognized in 2021.

Leases

In February 2016, the FASB issued ASU No. 2016-02 which created ASC Topic 842, “Leases,” to require balance sheet recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. In July 2018, the FASB issued ASU 2018-11, to provide another transition method in addition to the existing transition method, allowing entities to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Additionally, the FASB has issued other ASU’s to clarify application of the guidance in the original standard and to provide practical expedients for applying the standard, all of which are effective upon adoption. For non-public entities, this standard is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022.

The Company has adopted the standard as of January 1, 2022. This standard requires the Company to recognize right-of-use assets and lease liabilities on the balance sheet for identified property that is subject to operating lease agreements. The Company elected to adopt this standard by applying the additional transition method set forth in ASU 2018-11, whereby the Company implemented the provisions of the new standard to existing leases by recognizing and measuring lease assets and liabilities on the balance sheet as of January 1, 2022, as well as a cumulative-effect adjustment to the opening balances of members’ accumulated deficit. The impact on retained deficit was de-minimis. Consequently, the reporting of leases for the prior year continues to be provided in accordance with ASC Topic 840, which was effective during that period. The Company elected the package of practical expedients permitted under the transition guidance within ASC Topic 842.

Income Taxes

The Company has elected to be taxed as a partnership under the provisions of the Internal Revenue Code of 1986, as amended (the “Code”). Under these provisions, the taxable income or tax loss of the Company is passed through to its members and reported on their individual tax returns. Therefore, no provision or liability and no tax benefit or asset related to federal income taxes has been included in these financial statements. There were neither liabilities nor deferred tax assets relating to uncertain income tax positions taken or expected to be taken on the tax returns.

The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. When applicable, the Company recognizes interest and penalties related to uncertain tax positions in income tax expense.

Research and Development Cost

The Company accounts for research and development cost (“R&D”) in accordance with FASB ASC Topic 730, “Research and Development.” R&D represents costs incurred in performing research aimed at the discovery of new knowledge and the advancement of techniques to bring significant improvements to products and processes. Costs incurred in developing a product include consulting, engineering, construction and costs incurred to build prototypes.

Fair Value of Financial Instruments

Level 1	—	Inputs based on unadjusted quoted market prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2	—	Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active or for which all significant inputs are observable or can be corroborated by observable market data.
Level 3	—	Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are both unobservable for the asset and liability in the market and significant to the overall fair value measurement.

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. The Company establishes the fair value of its assets and liabilities using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and establishes a fair value hierarchy based on the inputs used to measure fair value. The recorded amounts of certain financial instruments, including accounts payable, accrued expenses, and other liabilities approximate fair value due to their relatively short maturities.

Share-Based Compensation

Earnings (Loss) Per Unit

The Company computes basic earnings per unit (“EPS”) by dividing loss available to members by the weighted average number of participating units outstanding for the reporting period. All securities that meet the definition of a participating security, irrespective of whether the securities are convertible, nonconvertible, or potential common stock securities, shall be included in the computation of basic EPS using the two-class method. However, when the different classes of units have identical rights and privileges except voting rights, whereby they share equally in dividends and residual net assets on a per unit basis, the classes can be combined and presented as one class for EPS purposes.

Diluted loss per share is calculated by dividing net earnings (loss) by the weighted average number of participating units and dilutive participating unit equivalents outstanding. During the periods when they are anti-dilutive, participating unit equivalents, if any, are not considered in the computation. As of December 31, 2022 and 2021, there were no anti-dilutive participating unit equivalents outstanding.

New Accounting Pronouncements

Recently Adopted Accounting Standards

In August 2020, the FASB issued Accounting Standards Update (“ASU”) 2020-06, “Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40)”. ASU 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU is part of the FASB’s simplification initiative, which aims to reduce unnecessary complexity in US GAAP. The ASU’s amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Company has adopted ASU 2020-06 as of January 1, 2021 and it did not have a material impact on the financial statements.

Recently Issued Accounting Standards

The Company 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. The Company 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.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments — Credit Losses” (Topic 326), which requires that an entity measure and recognize expected credit losses for financial assets held at amortized cost and replaces the incurred loss impairment methodology in current GAAP with a methodology that requires consideration of a broader range of information to estimate credit losses. The guidance also modifies the impairment model for available-for-sale debt securities. ASU 2016-13 is effective for the Company’s fiscal year beginning January 1, 2023. The Company is currently evaluating the impact of ASU 2016-13 on its financial statements.

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”. ASU 2020-04 provides guidance on optional expedients for a limited time to ease the operational burden in accounting for (or recognizing the effects of) reference rate reform (LIBOR) on financial reporting. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848) — Deferral of the Sunset Date of Topic 848 (ASU 2022-06)”, which extends the optional transition relief to ease the potential burden in accounting for reference rate reform on financial reporting. The transition relief is provided through December 31, 2024 based on the expectation that the LIBOR will cease to be published as of June 30, 2023. The amendments are effective prospectively at any point through December 31, 2024. The Company will continue to monitor new contracts that could potentially be eligible for contract modification relief through December 31, 2024.

Note 7 — PREFERRED UNITS

The Company is authorized to issue preferred units which are divided into Series A Preferred Units and Series B Preferred Units. The Company issued 82,142 Series B Preferred units in 2022 and 84,092 Series A Preferred units 2021 with net capital raises of $4,447,338 and $4,454,888 in 2022 and 2021, respectively. The Company intends to use the additional capital from the preferred issuances to continue its prototype development both internally and in conjunction with strategic partners with the goal of moving closer to product purchase commitments that can lead to commercial sales. The preferred units offer liquidation preferences and can be converted into interests of the most senior class of units issued after giving effect to certain new equity financings over certain dollar thresholds and valuations. The preferred units are non-voting.

Note 8 — MEMBERS’ CONTRIBUTIONS, OPTIONS AND WARRANTS

The Company is authorized to issue common units and preferred units. The common units are divided into Class A, Class B and Class C common units. The Class A common units, Class B common units and Class C common units shall be identical, except with respect to certain voting and approval rights. The Class A common units and Class B common units shall have the rights to designate certain Managers of the Company. The Class C common units shall be non-voting and shall entitle the holders thereof only to the economic rights of a holder of common units. See Note 7 for preferred units.

Profits and Losses are allocated based on provisions of the Company’s operating agreement.

As of December 31, 2022, the Company has issued 200,000 Class A common units 1,201,419 Class B common units and no Class C common units.

Warrants

In 2020, the Company issued 284,790 warrants in connection with equity contributions. All of the warrants had a strike price of $2.86 per unit, and a portion of the warrants in 2022 were exercised on a cashless basis. The exercise of warrants in 2022 and 2021 resulted in the issuance of 198,464 and 30,000 Class B common units, for $525,399 and $85,800, respectively.

There were 19,300 and 254,790 warrants outstanding at December 31, 2022 and 2021, respectively. The 19,300 warrants outstanding at December 31, 2022 expire on October 15, 2024.

Options

During 2020, the Company issued 115,000 options (90,000 at an exercise price of $0.625 and 25,000 at an exercise price of $2.86), which all immediately vested. It was determined that the fair value of the options at grant date was zero given the development stage of the Company.

The Company issued 15,000 options that immediately vested during early 2021 to the new Chief Financial Officer and a new board member at an exercise price equal to $2.86 per unit, equivalent to the price paid per unit when the Company completed its equity raise in late 2020. It was determined that the fair value of the options at grant date was zero given the development stage of the Company. No options were issued in 2022.

Of the 130,000 options outstanding at year-end 2022, 65,000 options expire on September 22, 2030, 25,000 options expire on October 15, 2025, 25,000 options expire on December 7, 2030, 3,000 options expire on March 15, 2031 and 12,000 options expire on April 8, 2031.

The Company is involved in various legal matters arising in the normal course of business. In the opinion of the Company’s management and legal counsel, the amount of losses that may be sustained, if any, would not have a material effect on the financial position and results of operations of the Company.

Risks and Uncertainties

The Company, as an early-stage business without any current operations, product sales or revenue, has historically been dependent upon the sourcing of external capital to fund its overhead and product development costs. This is a typical situation for any early-stage company without product sales to be in, and the Company raised additional capital in 2022 and 2021 via the exercise of warrants and issuance of preferred units.

License Agreement

In October 2021, the Company entered into a patent license agreement with a third party whereby the third party granted the Company rights to use certain of their patents in exchange for an upfront payment and royalties based on a percentage of net sales until such patents expire. In connection with this, the Company agreed to a minimum royalty amount of $50,000 for the year ended December 31, 2022, which has been accrued by the Company in the accompanying balance sheet. Future minimum royalties are as follows:

Year Ending December 31,

NOTES TO THE FINANCIAL STATEMENTS

Note 1 — ORGANIZATION AND BUSINESS OPERATIONS

On June 5, 2023, XPDB, a Delaware corporation, and Merger Sub, a Delaware limited liability company and wholly owned subsidiary of XPDB, entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time in accordance with its terms, the “Merger Agreement”) with the Company, pursuant to which, and subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger” and, along with the transactions contemplated in the Merger Agreement, the “Transactions”) , with the Company surviving the Merger as a wholly owned subsidiary of XPDB. Following the closing of the Merger (the “Closing”), XPDB will be renamed “Montana Technologies Corporation” (the “Post-Combination Company”). The transaction is subject to stockholder approvals and other closing conditions.

Note 2 — LIQUIDITY AND GOING CONCERN

Historically, the Company’s primary sources of liquidity have been cash flows from contributions from founders or other investors. The Company reported operating losses for the six months ended June 30, 2023 and negative cash flows from operations of $1,856,812 for the six months ended June 30, 2023. As of June 30, 2023, the Company had an aggregate cash balance of $3.5 million, a net working capital of $1.5 million and accumulated deficit of $9.1 million.

The Company’s future capital requirements will depend on many factors, including the Company’s timing and extent of its research and development efforts, building of facilities and establishment of a sales and marketing team. In order to finance these opportunities, the Company will need to raise additional financing. While there can be no assurances, the Company intends to raise such capital through issuances of additional equity raises as well as debt securities in the capital markets if necessary. If additional financing is required from outside sources, the Company may not be able to raise such capital on terms acceptable to the Company or at all. If the Company is unable to raise additional capital when desired, the Company’s business, results of operations and financial condition would be materially and adversely affected.

As a result of the above, in connection with the Company’s assessment of going concern considerations in accordance with the 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,” the Company’s management has determined that the its liquidity condition raises substantial doubt about the its ability to continue as a going concern through twelve months from the date these condensed financial statements are available to be issued. These condensed financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

Note 3 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information, expressed in U.S. dollars. Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. The accompanying condensed consolidated financial statements reflect all adjustments including normal recurring adjustments, which, in the opinion of the Company’s management, are necessary to present fairly the financial position, results of operations, and cash flows for the periods presented in accordance with GAAP. The results of operations of any interim period are not necessarily indicative of the results of operations to be expected for the full fiscal year. References to GAAP issued by the FASB in these accompanying notes to the condensed financial statements are to the FASB Accounting Standards Codification (“ASC”). The December 31, 2022 condensed consolidated balance sheet herein was derived from the audited financial statements at that date, but does not include all disclosures including notes required by GAAP for complete financial statements.

Note 3 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

Use of Estimates

Some of the more significant estimates include estimates of amortization and depreciation and estimates relating to leases. Due to the uncertainty involved in making estimates, actual results could differ from those estimates which could have a material effect on the financial condition and results of operations in future periods.

Cash and Concentration of Credit Risk

The Company considers all highly liquid investments with a maturity of 90 days or less at the time of purchase to be cash equivalents. The carrying values of cash and cash equivalents approximate their fair values due to the short-term nature of these instruments. As of June 30, 2023 and December 31, 2022, there were no cash equivalents. The Company maintains cash balances at financial institutions that may exceed the Federal Deposit Insurance Corporation’s insurance limits. The amounts over these insured limits as of June 30, 2023 and December 31, 2022 was $3,273,090 and $4,961,486, respectively. The Company mitigates this concentration of credit risk by monitoring the credit worthiness of the financial institutions. No losses have been incurred to date on any deposits.

Income Taxes

The Company has elected to be taxed as a partnership under the provisions of the Code. Under these provisions, the taxable income or tax loss of the Company is passed through to its members and reported on their individual tax returns. Therefore, no provision or liability and no tax benefit or asset related to federal income taxes has been included in these financial statements. There were neither liabilities nor deferred tax assets relating to uncertain income tax positions taken or expected to be taken on the tax returns.

Research and Development Cost

Fair Value of Financial Instruments

		Level 1 —		Inputs based on unadjusted quoted market prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
		Level 2 —		Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active or for which all significant inputs are observable or can be corroborated by observable market data.
		Level 3 —		Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are both unobservable for the asset and liability in the market and significant to the overall fair value measurement.

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. The Company establishes the fair value of its assets and liabilities using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and establishes a fair value hierarchy based on the inputs used to measure fair value. The recorded amounts of certain financial instruments, including accounts payable, accrued expenses, and other liabilities approximate fair value due to their relatively short maturities and are classified as level 1.

Share-Based Compensation

Earnings (Loss) Per Unit

Diluted loss per share is calculated by dividing net earnings (loss) by the weighted average number of participating units and dilutive participating unit equivalents outstanding. During the periods when they are anti-dilutive, participating unit equivalents, if any, are not considered in the computation. As of June 30, 2023 and 2022, there were no anti-dilutive participating unit equivalents outstanding.

The earnings per share presented in the statements of operations is based on the following for the three months ended June 30, 2023 and 2022:

New Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments — Credit Losses” (Topic 326), which requires that an entity measure and recognize expected credit losses for financial assets held at amortized cost and replaces the incurred loss impairment methodology in current GAAP with a methodology that requires consideration of a broader range of information to estimate credit losses. The guidance also modifies the impairment model for available-for-sale debt securities. ASU 2016-13 is effective for the Company’s fiscal year beginning January 1, 2023. The adoption of ASU 2016-13 had no impact on the financial statements.

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”. ASU 2020-04 provides guidance on optional expedients for a limited time to ease the operational burden in accounting for (or recognizing the effects of) reference rate reform (LIBOR) on financial reporting. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848)–Deferral of the Sunset Date of Topic 848 (ASU 2022-06)”, which extends the optional transition relief to ease the potential burden in accounting for reference rate reform on financial reporting. The transition relief is provided through December 31, 2024 based on the expectation that the LIBOR will cease to be published as of June 30, 2023. The amendments are effective prospectively at any point through December 31, 2024. The Company will continue to monitor new contracts that could potentially be eligible for contract modification relief through December 31, 2024.

Note 4 — PROPERTY AND EQUIPMENT

Note 7 — PREFERRED UNITS

The Company is authorized to issue preferred units which are divided into Series A Preferred Units and Series B Preferred Units. The Company intends to use the additional capital from the preferred issuances to continue its prototype development both internally and in conjunction with strategic partners with the goal of moving closer to product purchase commitments that can lead to commercial sales. The preferred units offer liquidation preferences and can be converted into interests of the most senior class of units issued after giving effect to certain new equity financings over certain dollar thresholds and valuations. The preferred units are non-voting.

Note 9 — RELATED PARTY TRANSACTIONS

The Company has a property lease agreement with its Chief Executive Officer as discussed in Note 6.

Note 10 — COMMITMENTS AND CONTINGENCIES

Risks and Uncertainties

The Company, as an early-stage business without any current operations, product sales or revenue, has historically been dependent upon the sourcing of external capital to fund its overhead and product development costs. This is a typical situation for any early-stage company without product sales to be in, and the Company raised additional capital via the exercise of warrants and issuance of preferred units.

License Agreement

In October 2021, the Company entered into a patent license agreement with a third party whereby the third party granted the Company rights to use certain of their patents in exchange for an upfront payment and royalties based on a percentage of net sales until such patents expire. In connection with this, the Company agreed to a minimum royalty amount of which $75,000 and $25,000 was expensed for the six months ended June 30, 2023 and 2022 and $75,000 and $50,000 was accrued by the Company in the accompanying condensed balance sheets as of June 30, 2023 and December 31, 2022, respectively.

Future minimum royalties are as follows as of June 30, 2023:

Remaining of 2023	$	75,000
2024		250,000
2025 and each year through the date the patents expire		300,000

Note 11 — SUBSEQUENT EVENTS

Subsequent events have been evaluated through October 2, 2023, which is the date the financial statements were available to be issued. The Company’s management has identified the following subsequent events:

On October 27, 2021, the Company entered into a joint venture with CATL US Inc. (“CATL US”), an affiliate of CATL, pursuant to which we and CATL US formed CAMT Climate Solutions Ltd., a limited liability company organized under the laws of Hong Kong (“CAMT”). The Company and CATL US both own 50% of CAMT’s issued and outstanding shares.

Note 11 — SUBSEQUENT EVENTS (cont.)

Pursuant to the Amended and Restated Joint Venture Agreement for CAMT, entered into on September 29, 2023 (the “A&R Joint Venture Agreement”), the Company and CATL US have each agreed to contribute $6 million to CAMT. Of this $6 million, we expect to make an initial contribution of $2 million prior to December 31, 2023, with the remaining $4 million contributed over the next three years based on a business plan and operating budgets to be agreed between us and CATL US. Any additional financing beyond the initial $12 million (i.e., $6 million from each of Montana and CATL US) will be subject to the prior mutual agreement of Montana and CATL US. CAMT is managed by a four-member board of directors, with two directors (including the chairman) designated by CATL US and two directors (including the vice chairman) designated by Montana. In the event of an equal vote, the chairman may cast the deciding vote. Certain reserved matters, including debt issuances exceeding $5 million in a single transaction or in aggregate within a fiscal year, amendments to CAMT’s constitutional documents the annual financial budget of CAMT, and any transaction between CAMT and CATL US or Montana in an amount exceeding $10 million in a single transaction or in aggregate within a fiscal year, require the unanimous vote of both CATL US and Montana or all directors.

The purpose of the Company’s joint venture with CATL US is to commercialize our AirJoule technology in Asia and Europe and, pursuant to the A&R Joint Venture Agreement, CAMT has the exclusive right to commercialize our AirJoule technology in those territories. Subject to the oversight of CAMT’s board, CATL US is responsible for managing the day-to-day operations of CAMT (including the nomination and replacement of the Chief Executive Officer of CAMT), and is responsible for providing CAMT and any subsidiaries formed by CAMT with, among other things, administrative services, supply chain support, assistance in obtaining required permits and approvals, and assistance in purchasing or leasing land and equipment.

Article II
MERGER CONSIDERATION; CONVERSION OF SECURITIES

Section 2.1. Treatment of Equity Interests.

(a) Company Units. At the Effective Time (after giving effect to the Company Preferred Conversion), by virtue of the Merger and without any action on the part of any Parent Party, the Company or any Company Equityholder, the issued and outstanding Company Units held by each Company Unitholder immediately prior to the Effective Time (other than (i) any Company Units subject to or relating to Company Options (which shall be subject to Section 2.1(b)) and (ii) if applicable, any Company Units subject to or relating to Company Warrants (which shall be subject to Section 2.1(c))) shall be canceled and converted into the right to receive a portion of the Net Merger Consideration as follows:

(i) each Company Class A Common Unit issued and outstanding immediately prior to the Effective Time shall be cancelled and converted into the right to receive (i) a fractional number of shares of New Parent Class B Common Stock equal to the Exchange Ratio and (ii) if applicable, a number of shares of Earnout Stock in accordance with Section 2.4;

(ii) each Company Class B Common Unit issued and outstanding immediately prior to the Effective Time shall be cancelled and converted into the right to receive (i) a fractional number of shares of New Parent Class A Common Stock equal to the Exchange Ratio and (ii) if applicable, a number of shares of Earnout Stock in accordance with Section 2.4; and

(iii) each Company Class C Common Unit issued and outstanding immediately prior to the Effective Time shall be cancelled and converted into the right to receive (i) a fractional number of shares of New Parent Class A Common Stock equal to the Exchange Ratio and (ii) if applicable, a number of shares of Earnout Stock in accordance with Section 2.4.

(b) Company Options. As of the Effective Time, by virtue of the Merger and without any action on the part of any Parent Party, the Company or any Company Equityholder, each Company Option that is then outstanding shall be converted into (i) an option to purchase shares of New Parent Class A Common Stock upon the same terms and conditions as are in effect with respect to the corresponding Company Option immediately prior to the Effective Time, including with respect to vesting and termination-related provisions (each, a “New Parent Option”) except that (a) such New Parent Option shall relate to that whole number of shares of New Parent Class A Common Stock (rounded down to the nearest whole share) equal to (x) the number of Company Common Units subject to such Company Option immediately prior to the Effective Time multiplied by (y) the Exchange Ratio, and (b) the

Annex A-3

Table of Contents

exercise price per share for each such New Parent Option shall be equal to the exercise price per Company Common Unit of such Company Option in effect immediately prior to the Effective Time divided by the Exchange Ratio (the exercise price per share, as so determined, being rounded up to the nearest full cent) and (ii) if applicable, the right to receive a number of shares of Earnout Stock, if any, determined in accordance with and subject to Section 2.4. Any such conversion of a Company Option into a New Parent Option will be made in a manner consistent with Treasury Regulation Section 1.424-1, such that such conversion will not constitute a “modification” of such Company Options for purposes of Section 409A or, to the extent applicable, Section 424 of the Code.

(c) Company Warrants. As of the Effective Time, by virtue of the Merger and without any action on the part of any Parent Party, the Company or any Company Equityholder, each Company Warrant that is then outstanding shall be converted into a warrant to purchase shares of New Parent Class A Common Stock upon the same terms and conditions as are in effect with respect to the corresponding Company Warrant immediately prior to the Effective Time, including with respect to vesting and termination-related provisions (each, a “New Parent Warrant”) except that (i) such New Parent Warrant shall relate to that whole number of shares of New Parent Class A Common Stock (rounded down to the nearest whole share) equal to (x) the number of Company Common Units subject to such Company Warrant immediately prior to the Effective Time multiplied by (y) the Exchange Ratio, and (ii) the exercise price per share for each such New Parent Warrant shall be equal to (x) the exercise price per Company Common Unit of such Company Warrant in effect immediately prior to the Effective Time divided by (y) the Exchange Ratio (the exercise price per share, as so determined, being rounded up to the nearest full cent). Parent will assume each New Parent Warrant by a written instrument substantially similar in form and substance to such corresponding Company Warrant.

(d) Merger Sub Equity Interest. At the Effective Time, by virtue of the Merger and without any action on the part of any Party or any other Person, each Equity Interest of Merger Sub issued and outstanding immediately prior to the Effective Time shall be automatically cancelled and extinguished and converted into one common unit of the Surviving Company.

(e) Parent Class B Common Stock. At the Effective Time, in connection with the filing of the A&R Charter, each share of Parent Class B Common Stock that is issued and outstanding as of such time shall automatically convert in accordance with the terms of the A&R Charter into one (1) share of New Parent Class A Common Stock.

Section 2.2. Payment of the Merger Consideration. At or prior to the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, in trust for the benefit of the Company Unitholders, evidence of book-entry shares representing a number of whole shares of New Parent Class A Common Stock and New Parent Class B Common Stock constituting the Net Merger Consideration deliverable to the Company Unitholders pursuant to this Article II. Any such shares of New Parent Common Stock deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Agent Fund.” The Exchange Agent Fund shall be subject to the terms of this Agreement and the Exchange Agent Agreement. Subject to Section 2.3, at the Closing, Parent shall cause to be issued or paid from the Exchange Agent Fund to each Company Unitholder in accordance with this Article II immediately prior to the Effective Time, evidence of book-entry shares representing the number of shares of the applicable portion of the Net Merger Consideration. Notwithstanding anything to the contrary in this Agreement, under no circumstances shall Parent be required to issue more than the Aggregate Merger Consideration as calculated in accordance with Section 2.1 and, if applicable, the Earnout Stock as calculated in accordance with Section 2.4. No interest shall be paid or accrued upon the transfer of any Equity Interests. Promptly following the date that is one hundred eighty (180) days after the Effective Time, Parent shall instruct the Exchange Agent to deliver to Parent all documents in its possession relating to the Transactions, and the Exchange Agent’s duties shall terminate. Thereafter, any portion of the Net Merger Consideration that remains unclaimed shall be returned to Parent, and any Person that was a holder of Company Common Units as of immediately prior to the Effective Time that has not exchanged such Company Common Units for an applicable portion of the Net Merger Consideration in accordance with this Section 2.2 prior to the date that is one hundred eighty (180) days after the Effective Time, may transfer such Company Common Units to Parent and (subject to applicable abandoned property, escheat and similar Laws) receive in consideration therefor, and Parent shall promptly deliver, such applicable portion of the Net Merger Consideration without any interest thereupon. No Parent Party, the Company, the Surviving Company or the Exchange Agent shall be liable to any Person in respect of any of the Net Merger Consideration delivered to a public official pursuant to and in accordance with any applicable abandoned property, escheat or similar Laws. If any such Company Common Units shall not have not

Annex A-4

Table of Contents

been transferred immediately prior to such date on which any amounts payable pursuant to this Article II would otherwise escheat to or become the property of any Governmental Entity, any such amounts shall, to the extent permitted by applicable Law, become the property of the Surviving Company, free and clear of all claims or interest of any Person previously entitled thereto.

Section 2.3. Exchange Procedures for Company Unitholders.

(a) Payment Procedures. Prior to the Closing, the Company shall mail or otherwise deliver, or shall cause the Exchange Agent to mail or otherwise deliver, to each holder of Company Units evidenced by certificates entitled to receive a portion of the Net Merger Consideration pursuant to this Article II, a letter of transmittal reasonably acceptable to Parent and the Company or as may be reasonably required by the Exchange Agent (the “Letter of Transmittal”). Subject to the satisfaction of the conditions in Article VI, in the event that at least three (3) Business Days prior to the Closing Date, a holder of Company Equity Interests evidenced by certificates does not deliver to the Exchange Agent a duly executed and completed Company Letter of Transmittal, then such failure shall not alter, limit or delay the Closing; provided that such holder of Company Equity Interests evidenced by certificates shall not be entitled to receive its respective portion of the Net Merger Consideration until such Person delivers a duly executed and completed Company Letter of Transmittal to the Exchange Agent (in the case of a Company Letter of Transmittal). Upon delivery of such duly executed Company Letter of Transmittal by such holder of Company Equity Interests evidenced by certificates to the Exchange Agent, such holder of Company Equity Interests evidenced by certificates shall be entitled to receive, subject to the terms and conditions of this Agreement, the applicable portion of the Net Merger Consideration in respect of his, her or its Company Equity Interests referenced in such Company Letter of Transmittal and in accordance with this Article II. Until surrendered as contemplated by this Section 2.3, each share of Company Equity Interests shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the portion of the Net Merger Consideration to which such Company Equityholder is entitled pursuant to this Article II.

(b) No Further Rights. All Aggregate Merger Consideration issued in accordance with the terms of this Article II shall be deemed to have been exchanged and paid in full satisfaction of all rights pertaining to such Company Equity Interests relating thereto and there shall be no further registration of transfers on the transfer books of the Surviving Company of the Company Equity Interests that were issued and outstanding immediately prior to the Effective Time. From and after the Effective Time, holders of Company Equity Interests shall cease to have any rights as Company Equityholders, except as provided in this Agreement or by applicable Law.

(c) Changes in Parent Stock. If at any time between the date of this Agreement and the Effective Time, the outstanding shares of Parent Common Stock shall have been increased, decreased, changed into or exchanged for a different number of kind of shares or securities as a result of a subdivision, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, combination or other similar change in capitalization, in each case other than in connection with the Merger, then the Exchange Ratio shall be equitably adjusted to reflect such change; provided, that nothing in this Section 2.3(c) shall be construed to permit Parent to take any action with respect to its securities that is prohibited by the terms of this Agreement.

(d) Fractional Shares. Notwithstanding anything to the contrary contained herein, no evidence of book-entry shares representing fractional shares of New Parent Common Stock shall be issued in exchange for Company Equity Interests. Each Person who would otherwise be entitled to a fraction of a share of New Parent Class A Common Stock or New Parent Class B Common Stock (after aggregating all fractional shares of such New Parent Class A Common Stock or New Parent Class B Common Stock, as the case may be, that otherwise would be received by such Person in connection with the Closing) shall instead have the number of shares of New Parent Class A Common Stock or New Parent Class B Common Stock issued to such Person rounded up to the nearest whole share of New Parent Class A Common Stock or New Parent Class B Common Stock, as the case may be.

(e) Dividends. No dividends or other distributions declared with respect to New Parent Common Stock, the record date for which is at or after the Effective Time, shall be paid to any Company Equityholder that has not delivered a properly completed, duly executed Company Letter of Transmittal. After the delivery of such materials, the Company Equityholder shall be entitled to receive any such dividends or other distributions, without any interest thereon, which had become payable with respect to New Parent Common Stock issuable to such Company Equityholder.

Section 2.4. Company Earnout.

(a) Subject to the terms and conditions of this Section 2.4, following the Closing, the Eligible Equityholders, (in each case, in accordance with their respective Pro Rata Share), shall be eligible to receive distributions, in the aggregate, if applicable, of an additional number of shares of New Parent Class A Common Stock (“Earnout Stock”), in each case, equal to (i) an Earnout Milestone Amount divided by (ii) $10.00 (if applicable, an “Earnout Stock Payment”). Notwithstanding anything to the contrary contained in this Section 2.4, in no event shall the aggregate sum of all Earnout Milestone Amounts achieved exceed $200,000,000 (the “Maximum Earnout Milestone Amount”). Upon the achievement of an Earnout Milestone Amount, an Earnout Stock Payment will be made and Earnout Stock shall be distributed to the Eligible Equityholders in accordance with this Section 2.4 upon the relevant Commission Date (whether or not such Commission Date occurs after the Earnout Expiration Date).

(b) An Earnout Milestone Amount shall become due and payable to the Eligible Equityholders in the form of Earnout Stock only upon full completion of construction and operational viability (for the avoidance of doubt, including all permitting, regulatory approvals and necessary or useful inspections so that Parent or its Subsidiaries can start production of increased capacity of its key components and assemblies) (the date of such completion and viability, the “Commission Date”) of new production capacity (any such incremental new production capacity, the “New Company Production Capacity”) of Parent or its Subsidiaries key components or assemblies based solely on demand from bona fide customer commitments evidenced by binding Contracts with a known price or pricing formula (i.e., “cost plus”) or, so long as the Parent Board believes a non-binding letter of intent or indication of interest or similar writing is substantially likely to become a binding Contract, in the Parent Board’s sole discretion, evidenced by such non-binding writing(s), that exceeds, in the Parent Board’s sole discretion, a level of production capacity that is expected to generate Annualized EBITDA of more than $150,000,000 (the “Threshold Annualized EBITDA”) and each “Earnout Milestone Amount,” which shall be determined by the Parent Board in its sole discretion promptly after the relevant Commission Date shall equal (i) the ratio of (x) (1) the Annualized EBITDA that is expected from the New Company Production Capacity (the “Expected Annualized EBITDA”) less (2) (A) the Threshold Annualized EBITDA plus (B) all previously Expected Annualized EBITDA amounts associated with previous New Company Production Capacity for which previous Earnout Milestone Amounts were achieved divided by (y) $150,000,000 multiplied by (ii) the Maximum Earnout Milestone Amount; provided, however, that the aggregate Expected Annualized EBITDA shall not exceed $300,000,000.

(c) In the event that any Earnout Milestone Amount is not achieved prior to the fifth anniversary of the Closing Date (the “Earnout Expiration Date”), then no Earnout Stock Payment shall be owed or due, and no Earnout Stock shall be distributed, with respect to such Earnout Milestone Amounts not yet achieved and all liabilities and obligations of this Section 2.4 shall immediately terminate with respect to such Earnout Milestone Amounts without any further action of the Parent Parties, the Company or the Eligible Equityholders.

(d) If applicable, the Earnout Stock issuable upon an Earnout Stock Payment shall be equitably adjusted for stock splits, stock dividends and stock combinations and recapitalizations affecting the New Parent Common Stock.

(e) Whenever any provision of this Section 2.4 provides that the Parent Board is permitted or required to make a decision in its “sole discretion” or “discretion”, any such decision shall be made by a majority of the “Independent Directors” (as determined under applicable stock exchange and SEC rules and regulations) then serving on the Parent Board. For the avoidance of doubt, and notwithstanding anything to the contrary set forth in this Section 2.4, the Parent Board will have sole discretion in determining whether an Earnout Milestone Amount has been achieved (including the forecasting of Annualized EBITDA related to any New Company Production Capacity), the calculation of the Earnout Milestone Amount in accordance with the terms of this Section 2.4, the determination of when a Commission Date has occurred and whether to consent to a Transfer. Parent acknowledges and agrees that the possibility of the Eligible Equityholders receiving the Earnout Stock comprises a material inducement for the Company to enter into this Agreement. Notwithstanding anything in this Agreement to the contrary, until the Earnout Expiration Date, (a) Parent shall use commercially reasonable efforts to cause the Parent, the Surviving Company and their Subsidiaries to operate in accordance with good industry practice, and (b) neither Parent nor the Parent Board will take any actions, or omit to take any actions, for

Annex A-6

Table of Contents

the primary purpose of, or that would, without a good faith business reason unrelated to the results described in the following clauses, reasonably be expected to result in, (x) thwarting or inhibiting the achievement of achieving the Maximum Earnout Milestone Amount or the Earnout Stock Payment in any material respect or (y) otherwise frustrating or avoiding Parent’s obligations under this Agreement with respect to the Earnout Stock in any material respect.

(f) In the event that, prior to the Earnout Expiration Date, (i) Parent effects a sale (directly or indirectly) of all or substantially all of the assets of Parent to a third party, or (ii) Parent effects a merger or consolidation or other transaction involving Parent or the Surviving Company, in each case which results in Parent or the Surviving Company being controlled, directly or indirectly, by a third party following the Closing (a “Triggering Transaction”), then, in each such case, Parent shall cause the third party acquirer or successor in such Triggering Transaction to expressly assume all of the obligations under this Agreement with respect to the Earnout Stock.

(g) Except as set forth in the previous paragraph, the Company, on behalf of the Eligible Equityholders, acknowledges and agrees that the neither Parent Parties have made, nor are making, any representations or warranties or other promises regarding the current or future operations of Parent or the Surviving Company and their respective businesses and assets and any such representations or warranties or other promises have been and are hereby expressly disclaimed, and the Company, on behalf of the Eligible Equityholders, acknowledges and agrees that in no case shall any Eligible Equityholder have or assert any claims, proceedings or actions against any Parent Party or the Surviving Company or any of their respective Affiliates or Representatives based on the failure to achieve any Earnout Milestone Amount or Commission Date or meet any other performance projections, forecasts or estimates.

(h) The right of an Eligible Equityholder to receive any portion of any Earnout Stock Payment (i) is solely a contractual right and is not a security for purposes of any federal or state securities Laws (and shall confer upon each Eligible Equityholder only the rights of a general creditor under applicable state Law), (ii) does not give any Company Equityholder any dividend or distribution rights, voting rights, liquidation rights, preemptive rights or other rights common to Parent equityholders, (iii) is not redeemable and (iv) may not be sold, assigned, pledged, gifted, conveyed, transferred or otherwise disposed, directly or indirectly, of (a “Transfer”), except, (x) in the case of a non-individual Person, by operation of Law or, in the case of an individual, by will or the Laws of descent and distribution, in each case with reasonable notice thereof to (and any purported Transfer in violation of this Section 2.4(h) shall be null and void).

(i) Notwithstanding anything in this Agreement to the contrary, any Earnout Stock issuable under this Section 2.4 in respect of a Company Option that was outstanding as of immediately prior to the Effective Time shall be issued to the holder of such Company Option only if such holder continues to provide services (whether as an employee, director or individual independent contractor) to Parent or one of its Subsidiaries through the date on which such Earnout Stock is issued, as determined by the Parent Board, pursuant to this Section 2.4.

(j) Notwithstanding anything to the contrary contained herein, no fraction of a share of Earnout Stock will be issued, and each Person who would otherwise be entitled to a fraction of a share of Earnout Stock (after aggregating all fractional shares of Earnout Stock that otherwise would be received by such Person in connection with any Earnout Milestone Amount) shall instead have the number of shares of Earnout Stock issued to such Person rounded up to the nearest whole share of Earnout Stock.

Section 2.5. Withholding Rights. Each of the Parties, the Surviving Company and the Exchange Agent are entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to such payment under all applicable Laws. To the extent that amounts are so deducted or withheld by the Parties, the Surviving Company or the Exchange Agent, as the case may be, and timely remitted to the applicable Governmental Entity, such deducted or withheld amounts will be treated for all purposes of this Agreement as having been paid to the Person, in respect of which such deduction or withholding was made. The Parties shall cooperate in good faith to eliminate or reduce any such deduction or withholding (including through the request and provision of any statements, forms or other documents to reduce or eliminate any such deduction or withholding).

Each Party, and any Person asserting rights as a third-party beneficiary hereunder, irrevocably agrees that any Legal Dispute shall be brought exclusively in the courts of the State of Delaware; provided that if subject matter jurisdiction over the Legal Dispute is vested exclusively in the United States federal courts, such Legal Dispute shall be heard in the United States District Court for the District of Delaware. Each Party, and any Person asserting rights as a third-party beneficiary hereunder, hereby irrevocably and unconditionally submits to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by Law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding that is brought in any such court has been brought in an inconvenient forum.

EACH OF THE PARTIES AND ANY PERSON ASSERTING RIGHTS AS A THIRD-PARTY BENEFICIARY HEREUNDER MAY BRING A LEGAL DISPUTE ONLY IF HE, SHE OR IT IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS AGREEMENT OR THE TRANSACTIONS AND FOR ANY COUNTERCLAIM RELATING THERETO. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY NOR ANY PERSON ASSERTING RIGHTS AS A THIRD-PARTY BENEFICIARY SHALL ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS.

CAPITAL STOCK

The total number of shares of capital stock that the Corporation shall have authority to issue is [•], consisting of three classes as follows: [•] shares of Class A common stock, par value $0.0001 per share (“Class A Common Stock”); [•] shares of Class B common stock, par value $0.0001 per share (“Class B Common Stock” and, together with Class A Common Stock, “Common Stock”); and [•] shares of preferred stock, par value $0.0001 per share (“Preferred Stock”).

Upon the filing of this Second Amended and Restated Certificate of Incorporation (the “Effective Time”), each issued and outstanding share of capital stock of the Corporation shall convert automatically, on a one-for-one basis, into a share of Class A Common Stock, without any action required on the part of the Corporation or the holders thereof.

The Corporation has the authority to create and issue rights, warrants and options entitling the holders thereof to acquire from the Corporation any shares of its capital stock of any class or classes, with such rights, warrants and options to be evidenced by or in instrument(s) approved by the Board of Directors of the Corporation (the “Board of Directors”). The Board of Directors is empowered to set the exercise price, duration, times for exercise and other terms and conditions of such rights, warrants or options; provided, however, that the consideration to be received for any shares of capital stock issuable upon exercise thereof may not be less than the par value thereof.

The designations and the powers, privileges and rights, and the qualifications, limitations or restrictions thereof in respect of each class of capital stock of the Corporation are as follows:

A. COMMON STOCK.

1. General. The voting, dividend, liquidation, and other rights and powers of the Common Stock are subject to and qualified by the rights, powers and preferences of any series of Preferred Stock as may be designated by the Board of Directors and outstanding from time to time.

2. Voting.

a. Except as otherwise provided herein (including any Certificate of Designation) or otherwise required by law, the holders of the shares of Common Stock shall exclusively possess all voting power with respect to the Corporation.

b. Each share of Class A Common Stock shall entitle the record holder thereof as of the applicable record date to one (1) vote per share in person or by proxy on all matters submitted to a vote of the holders of Class A Common Stock, whether voting separately as a class or otherwise.

Annex B-2

Table of Contents

c. Each share of Class B Common Stock shall entitle the record holder thereof as of the applicable record date to [•] votes per share in person or by proxy on all matters submitted to a vote of the holders of Class B Common Stock, whether voting separately as a class or otherwise.

d. Except as otherwise required in this Second Amended and Restated Certificate of Incorporation, the holders of shares of Class A Common Stock and Class B Common Stock shall vote together as a single class (or, if any holders of shares of Preferred Stock are entitled to vote together with the holders of Class A Common Stock and Class B Common Stock, as a single class with such holders of Preferred Stock) on all matters submitted to a vote of stockholders of the Corporation.

e. Except as otherwise provided herein (including any Certificate of Designation) or otherwise required by law, at any annual or special meeting of the stockholders of the Corporation, holders of the Common Stock shall have the exclusive right to vote for the election of the Corporation’s directors and on all other matters properly submitted to a vote of the stockholders.

f. Except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Second Amended and Restated Certificate (including any Certificate of Designation) that relates solely to the rights, powers, preferences (or the qualifications, limitations or restrictions thereof) or other terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Second Amended and Restated Certificate (including any Certificate of Designation) or pursuant to the DGCL.

Subject to the rights of any holders of any outstanding series of Preferred Stock, the number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote thereon. Notwithstanding the immediately preceding sentence, the number of authorized shares of any particular class may not be decreased below the number of shares of such class then outstanding, plus (i) in the case of Class A Common Stock, the number of shares of Class A Common Stock issuable in connection with the exercise of all outstanding options, warrants, exchange rights, conversion rights or similar rights for Class A Common Stock, including in respect of Class A Common Stock issued upon conversion of Class B Common Stock, and (ii) in the case of Class B Common Stock, the number of shares of Class B Common Stock issuable in connection with the exercise of all outstanding options, warrants, exchange rights, conversion rights or similar rights for Class B Common Stock.

3. Permitted Ownership. From and after the effectiveness of this Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, shares of Class B Common Stock may be issued only to, and registered only in the name of, the Existing Owners and their respective Permitted Transferees (the Existing Owners, together with all such subsequent successors, assigns and Permitted Transferees, collectively, the “Permitted Class B Owners”). As used in this Second Amended and Restated Certificate of Incorporation, (A) “Existing Owner” means each of Matt Jore and Stu Porter, (B) “Permitted Transferee” means (i) a Permitted Class B Owner, (ii) Relatives of a Permitted Class B Owner, (iii) any trust, corporation, family partnership or limited liability company, the sole beneficiaries, stockholders, partners or members or which are a Permitted Class B Owner or Relatives of a Permitted Class B Owner, (iv) the heirs of any deceased Permitted Class B Owner, whether by will or intestacy and (v) any person that directly or indirectly controls, is controlled by or with a Permitted Class B Owner and (C) “Relative” means, with respect to any Permitted Class B Owner, his or her current or former spouse, siblings, parents, or spouse’s or former spouse’s parents or siblings or lineal descendants (whether natural or adopted) of such Permitted Class B Owner, his or her current or former spouse, siblings, parents or current or former spouse’s parents or siblings.

4. Dividends. Subject to applicable law and the rights and preferences of any holders of any outstanding series of Preferred Stock, the holders of Common Stock, as such, shall be entitled to the payment of dividends on the Common Stock when, as and if declared by the Board of Directors in accordance with applicable law. Except as otherwise provided in this Article IV, dividends of cash or property may not be declared or paid on any class of Common Stock unless a dividend of the same amount per share and same type of cash or property (or combination thereof) per share is concurrently declared or paid on all other classes of Common Stock.

Annex B-3

Table of Contents

5. Stock Adjustments. In no event will any stock dividend, stock split, reverse stock split, combination of stock, reclassification or recapitalization be declared or made on any class of Common Stock (each, a “Stock Adjustment”) unless a corresponding Stock Adjustment for all other classes of Common Stock at the time outstanding is made in the same proportion and the same manner (unless the holders of shares representing a majority of the voting power of any such other class of Common Stock (voting separately as a single class) waive such requirement in writing, in which event no such Stock Adjustment shall be made for such other class of Common Stock).

6. Liquidation. Subject to the rights and preferences of any holders of any shares of any outstanding series of Preferred Stock, in the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the funds and assets of the Corporation that may be legally distributed to the Corporation’s stockholders shall be distributed among the holders of the then outstanding Common Stock pro rata in accordance with the number of shares of Common Stock held by each such holder.

7. Equal Treatment. Except as expressly provided in this Article IV, all shares of Common Stock shall, as among each other, have the same rights and privileges and rank equally, share ratably and be identical in all respects as to all matters (unless holders of shares representing a majority of the voting power of any class of Common Stock (voting separately as a single class) waive such requirement in advance and in writing to different treatment as to such class of Common Stock, in which event different treatment may be permitted for such class of Common Stock). Without limiting the generality of the foregoing, unless holders of shares representing a majority of the voting power of any class of Common Stock (voting separately as a single class) waive such requirement in advance and in writing to different treatment as to such class of Common Stock, in which event different treatment may be permitted for such class of Common Stock, (i) in the event of a merger, consolidation or other business combination requiring the approval of the holders of the Corporation’s capital stock entitled to vote thereon (whether or not the Corporation is the surviving entity), the holders of any class of Common Stock shall have the right to receive, or the right to elect to receive, the same form of consideration and the same amount of consideration (on a per share basis), if any, as the holders of any other class of Common Stock, and (ii) in the event of (a) any tender or exchange offer to acquire any shares of Common Stock by any third party pursuant to an agreement to which the Corporation is a party or (b) any tender or exchange offer by the Corporation to acquire any shares of Common Stock, pursuant to the terms of the applicable tender or exchange offer, the holders of any class of Common Stock shall have the right to receive, or the right to elect to receive, the same form of consideration and the same amount of consideration (on a per share basis), if any, as the holders of any other class of Common Stock.

8. Conversion.

a. Voluntary Conversion. Each one (1) share of Class B Common Stock shall be convertible into one (1) share of Class A Common Stock at the option of the holder thereof at any time upon written notice to the transfer agent of the Corporation. Shares of Class B Common Stock that are converted into shares of Class A Common Stock as provided in this Article IV shall be retired and may not be reissued.

b. Automatic Conversion. On the earliest to occur of (i) the date that is seven (7) years from the date of this Second Amended and Restated Certificate of Incorporation and (ii) the first date on which the Permitted Class B Owners cease to own, in the aggregate, at least 33.0% of the number of shares of Class B Common Stock issued and held by the Permitted Class B Owners immediately following the Effective Time (or as to which the Permitted Class B Owners are entitled to as of such time), in each case, as equitably adjusted to reflect any stock splits, reverse stock splits, stock dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change or transaction (such date, the “Automatic Conversion Date”), each outstanding share of Class B Common Stock shall automatically, without any further action by the Corporation or any stockholder, convert into one (1) fully paid and nonassessable share of Class A Common Stock. Following such conversion, the reissuance of all shares of Class B Common Stock shall be prohibited, and such shares of Class B Common Stock shall be retired and may not be reissued. Upon such retirement, all references to Class B Common Stock in this Second Amended and Restated Certificate of Incorporation shall be eliminated.

Annex B-4

Table of Contents

c. Conversion upon Transfer. Immediately prior to any transfer of shares of Class B Common Stock to a person other than a Permitted Transferee, each share of Class B Common Stock being transferred shall automatically, without any further action by the Corporation or any stockholder, the transferor or the transferee, convert into one (1) fully paid and nonassessable share of Class A Common Stock.

d. Procedures. The Corporation may, from time to time, establish such policies and procedures relating to the conversion of Class B Common Stock into Class A Common Stock and the general administration of this dual class stock structure, including the issuance of stock certificates with respect thereto, as it may deem reasonably necessary or advisable, and may from time to time request that holders of shares of Class B Common Stock furnish certifications, affidavits or other proof to the Corporation as it deems necessary to verify the ownership of Class B Common Stock and to confirm that a conversion to Class A Common Stock has not occurred. A determination by the Secretary of the Corporation that a transfer results in a conversion to Class A Common Stock shall be conclusive and binding.

e. Immediate Effect. In the event of a conversion of shares of Class B Common Stock into shares of Class A Common Stock pursuant to this Article IV or upon the Automatic Conversion Date, such conversion(s) shall be deemed to have been made at the time that the transfer of shares occurred or immediately upon the Automatic Conversion Date, as applicable. Upon any conversion of Class B Common Stock to Class A Common Stock pursuant to this Article IV, all rights of the former holder of such shares of Class B Common Stock with respect to such shares of Class B Common Stock shall cease and the person or persons in whose names or names the certificate or certificates representing the shares of Class A Common Stock are to be issued shall be treated for all purposes as having become the record holder or holders of such shares of Class A Common Stock. The Corporation shall provide notice of such automatic conversion of shares of Class B Common Stock (the “Automatic Conversion”) to record holders of such shares of Class B Common Stock as soon as practicable following the Automatic Conversion; provided, however, that the Corporation may satisfy such notice requirements by providing such notice prior to the Automatic Conversion.

f. Reservation of Stock. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Class A Common Stock, solely for the purpose of effecting the conversion(s) of the shares of Class B Common Stock pursuant to this Article IV, such number of its shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Class B Common Stock into shares of Class A Common Stock.

9. Restrictions. All certificates or book entries representing shares of Class B Common Stock shall bear a legend substantially in the following form (or in such other form as the Board of Directors may determine):

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER THE ACT. THE SECURITIES REPRESENTED BY THIS [CERTIFICATE][BOOK ENTRY] ARE SUBJECT TO THE RESTRICTIONS (INCLUDING RESTRICTIONS ON TRANSFER) SET FORTH IN THE CERTIFICATE OF INCORPORATION OF THE CORPORATION AS IT MAY BE AMENDED AND/OR RESTATED (A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE CORPORATION AND SHALL BE PROVIDED FREE OF CHARGE TO ANY STOCKHOLDER MAKING A REQUEST THEREFOR).

B. PREFERRED STOCK

Shares of Preferred Stock may be issued from time to time in one or more series, each of such series to have such terms as stated or expressed herein and in the resolution or resolutions providing for the creation and issuance of such series adopted by the Board of Directors as hereinafter provided.

Annex B-5

Table of Contents

Authority is hereby expressly granted to the Board of Directors from time to time to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by adopting a resolution or resolutions providing for the issuance of the shares thereof and by filing a certificate of designation relating thereto in accordance with the DGCL (a “Certificate of Designation”), to determine and fix the number of shares of such series and such voting powers, full or limited, or no voting powers, and such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation thereof, dividend rights, conversion rights, redemption privileges and liquidation preferences, and to increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series as shall be stated and expressed in such resolutions, all to the fullest extent now or hereafter permitted by the DGCL. Without limiting the generality of the foregoing, the resolution or resolutions providing for the creation and issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law and this Second Amended and Restated Certificate (including any Certificate of Designation). Except as otherwise required by law, holders of any series of Preferred Stock shall be entitled only to such voting rights, if any, as shall expressly be granted thereto by this Second Amended and Restated Certificate (including any Certificate of Designation).

The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the DGCL.

ARTICLE V

BOARD OF DIRECTORS

For the management of the business and for the conduct of the affairs of the Corporation it is further provided that:

A. Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, the directors of the Corporation shall be classified with respect to the time for which they severally hold office into three classes, as nearly equal in number as possible and designated as Class I, Class II and Class III. The initial Class I directors shall serve for a term expiring at the first annual meeting of the stockholders following the date of this Second Amended and Restated Certificate; the initial Class II directors shall serve for a term expiring at the second annual meeting of the stockholders following the date of this Second Amended and Restated Certificate; and the initial Class III directors shall serve for a term expiring at the third annual meeting following the date of this Second Amended and Restated Certificate. At each annual meeting of the stockholders of the Corporation beginning with the first annual meeting of the stockholders following the date of this Second Amended and Restated Certificate, subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, the successors of the class of directors whose term expires at that meeting shall be elected to hold office for a term expiring at the annual meeting of the stockholders held in the third year following the year of their election. Each director shall hold office until his or her successor is duly elected and qualified or until his or her earlier death, resignation, disqualification or removal. No decrease in the number of directors shall shorten the term of any incumbent director. The Board of Directors is authorized to assign members of the Board of Directors already in office to Class I, Class II and Class III.

B. Except as otherwise expressly provided by the DGCL or this Second Amended and Restated Certificate, the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. The number of directors that shall constitute the whole Board of Directors shall be fixed exclusively by one or more resolutions adopted from time to time by the Board of Directors.

C. Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, the Board of Directors or any individual director may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least two-thirds (66 and 2/3%) of the voting power of all of the then outstanding shares of voting stock of the Corporation entitled to vote at an election of directors.

D. Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, except as otherwise provided by law, any vacancies on the Board of Directors resulting from death, resignation, disqualification, retirement, removal or other causes and any newly created directorships resulting from any increase in the number of directors shall be filled exclusively by the affirmative vote of a majority of the directors then in office, even though less than a quorum, or by a sole remaining director (other than any directors elected by the separate vote of one or more outstanding series of Preferred Stock), and shall not be filled by the stockholders. Any director appointed

Annex B-6

Table of Contents

in accordance with the preceding sentence shall hold office until the expiration of the term of the class to which such director shall have been appointed or until his or her earlier death, resignation, retirement, disqualification, or removal.

E. Whenever the holders of any one or more series of Preferred Stock issued by the Corporation shall have the right, voting separately as a series or separately as a class with one or more such other series, to elect directors at an annual or special meeting of stockholders, the election, term of office, removal and other features of such directorships shall be governed by the terms of this Second Amended and Restated Certificate (including any Certificate of Designation). Notwithstanding anything to the contrary in this Article V, the number of directors that may be elected by the holders of any such series of Preferred Stock shall be in addition to the number fixed pursuant to paragraph B of this Article V, and the total number of directors constituting the whole Board of Directors shall be automatically adjusted accordingly. Except as otherwise provided in the Certificate of Designation(s) in respect of one or more series of Preferred Stock, whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of such Certificate of Designation(s), the terms of office of all such additional directors elected by the holders of such series of Preferred Stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate (in which case each such director thereupon shall cease to be qualified as, and shall cease to be, a director) and the total authorized number of directors of the Corporation shall automatically be reduced accordingly.

F. In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to adopt, amend or repeal the Second Amended and Restated Bylaws of the Corporation (as amended and/or restated from time to time, the “Bylaws”). In addition to any vote of the holders of any class or series of stock of the Corporation required by applicable law or by this Second Amended and Restated Certificate (including any Certificate of Designation in respect of one or more series of Preferred Stock) or the Bylaws of the Corporation, the adoption, amendment or repeal of the Bylaws of the Corporation by the stockholders of the Corporation shall require the affirmative vote of the holders of at least two-thirds (66 and 2/3%) of the voting power of all of the then outstanding shares of voting stock of the Corporation entitled to vote generally in an election of directors.

G. The directors of the Corporation need not be elected by written ballot unless the Bylaws so provide.

ARTICLE VI

STOCKHOLDERS

A. Any action required or permitted to be taken by the stockholders of the Corporation must be effected at an annual or special meeting of the stockholders of the Corporation, and shall not be taken by written consent in lieu of a meeting. Notwithstanding the foregoing, any action required or permitted to be taken by the holders of any series of Preferred Stock, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice and without a vote, to the extent expressly so provided by the applicable Certificate of Designation relating to such series of Preferred Stock, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding shares of the relevant series of Preferred Stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation in accordance with the applicable provisions of the DGCL.

B. Subject to the special rights of the holders of one or more series of Preferred Stock, special meetings of the stockholders of the Corporation may be called, for any purpose or purposes, at any time only by or at the direction of the Board of Directors, the Chairperson of the Board of Directors, the Chief Executive Officer or the President, and shall not be called by any other person or persons.

C. Advance notice of stockholder nominations for the election of directors and of other business proposed to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws of the Corporation.

ARTICLE VII

LIABILITY

No director or officer of the Corporation shall have any personal liability to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director or officer, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or hereafter may be amended. Any amendment, repeal or modification of this Article VII, or the adoption of any provision of the Second Amended and

Annex B-7

Table of Contents

Restated Certificate inconsistent with this Article VII, shall not adversely affect any right or protection of a director or officer of the Corporation with respect to any act or omission occurring prior to such amendment, repeal, modification or adoption. If the DGCL is amended after approval by the stockholders of this Article VII to authorize corporate action further eliminating or limiting the personal liability of directors or officers, then the liability of a director or officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended.

ARTICLE VIII

FORUM SELECTION

Unless the Corporation consents in writing to the selection of an alternative forum, (a) the Court of Chancery (the “Chancery Court”) of the State of Delaware (or, in the event that the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action, suit or proceeding brought on behalf of the Corporation, (ii) any action, suit or proceeding asserting a claim of breach of a fiduciary duty owed by any director, officer or stockholder of the Corporation to the Corporation or to the Corporation’s stockholders, (iii) any action, suit or proceeding arising pursuant to any provision of the DGCL, the Bylaws or this Second Amended and Restated Certificate (as either may be amended from time to time) or (iv) any action, suit or proceeding asserting a claim against the Corporation governed by the internal affairs doctrine; and (b) subject to the preceding provisions of this Article VIII, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, including all causes of action asserted against any defendant to such complaint. If any action the subject matter of which is within the scope of clause (a) of the immediately preceding sentence is filed in a court other than the courts in the State of Delaware (a “Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (x) the personal jurisdiction of the state and federal courts in the State of Delaware in connection with any action brought in any such court to enforce the provisions of clause (a) of the immediately preceding sentence and (y) having service of process made upon such stockholder in any such action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder.

Any person or entity purchasing or otherwise acquiring any interest in any security of the Corporation shall be deemed to have notice of and consented to this Article VIII. This Article VIII is intended to benefit and may be enforced by the Corporation, its officers and directors, the underwriters to any offering giving rise to such complaint, and any other professional or entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the offering. Notwithstanding the foregoing, the provisions of this Article VIII shall not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts of the United States have exclusive jurisdiction.

If any provision or provisions of this Article VIII shall be held to be invalid, illegal or unenforceable as applied to any circumstances for any reason whatsoever, (a) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article VIII (including, without limitation, each portion of any paragraph of this Article VIII containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (b) the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.

ARTICLE IX
AMENDMENTS

A. Notwithstanding anything contained in this Second Amended and Restated Certificate to the contrary, in addition to any vote required by applicable law, the following provisions in this Second Amended and Restated Certificate may be amended, altered, repealed or rescinded, in whole or in part, or any provision inconsistent therewith or herewith may be adopted, only by the affirmative vote of the holders of at least two-thirds (66 and 2/3%) of the total voting power of all the then outstanding shares of stock of the Corporation entitled to vote thereon, voting together as a single class: Part B of Article IV, Article V, Article VI, Article VII, Article VIII and this Article IX.

Annex B-8

Table of Contents

B. If any provision or provisions of this Second Amended and Restated Certificate shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Second Amended and Restated Certificate (including, without limitation, each portion of any paragraph of this Second Amended and Restated Certificate containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not, to the fullest extent permitted by applicable law, in any way be affected or impaired thereby and (ii) to the fullest extent permitted by applicable law, the provisions of this Second Amended and Restated Certificate (including, without limitation, each such portion of any paragraph of this Second Amended and Restated Certificate containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent permitted by law.

1.1 Registered Office.

The address of the registered office of Montana Technologies Corporation (the “Corporation”) in the State of Delaware, and the name of its registered agent at such address, shall be as set forth in the Corporation’s certificate of incorporation, as the same may be amended and/or restated from time to time (the “Certificate of Incorporation”).

The Corporation may have additional offices at any place or places, within or outside the State of Delaware, as the Corporation’s board of directors (the “Board”) may from time to time establish or as the business and affairs of the Corporation may require.

Article II — Meetings of Stockholders

2.1 Place of Meetings.

Meetings of stockholders shall be held at any place, within or outside the State of Delaware, designated by the Board. The Board may, in its sole discretion, determine that a meeting of stockholders shall not be held at any place, but may instead be held solely by means of remote communication as authorized by Section 211(a)(2) of the General Corporation Law of the State of Delaware (the “DGCL”). In the absence of any such designation or determination, stockholders’ meetings shall be held at the Corporation’s principal executive office, whether within or outside of the State of Delaware.

2.2 Annual Meeting.

The Board shall designate the date and time of the annual meeting. At the annual meeting, the stockholders entitled to vote on such matters shall elect those directors of the Corporation to fill any term of a directorship that expires on the date of such annual meeting and may transact any other business as may properly be brought before the meeting in accordance with Section 2.4. The Board may postpone, reschedule or cancel any previously scheduled annual meeting of stockholders.

2.3 Special Meeting.

Special meetings of the stockholders may be called only by such persons and only in such manner as set forth in the Certificate of Incorporation.

The foregoing clause (iii) shall be the exclusive means for a stockholder to propose business to be brought before an annual meeting of the stockholders. The only matters that may be brought before a special meeting are the matters specified in the notice of meeting given by or at the direction of the person calling the meeting pursuant to Section 2.3, and stockholders shall not be permitted to propose business

For purposes of this Section 2.4, “present in person” shall mean that the stockholder proposing that the business be brought before the annual meeting of the Corporation, or a qualified representative of such proposing stockholder, appear at such annual meeting. A “qualified representative” of such proposing stockholder shall be a duly authorized officer, manager or partner of such stockholder or any other person authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders. Stockholders seeking to nominate persons for election to the Board must comply with Section 2.5, and this Section 2.4 shall not be applicable to nominations except as expressly provided in Section 2.5.

(b) For business to be properly brought before an annual meeting by a stockholder, the stockholder must (i) provide Timely Notice (as defined below) thereof in writing and in proper form to the Secretary of the Corporation and (ii) provide any updates or supplements to such notice at the times and in the forms required by this Section 2.4. To be timely, a stockholder’s notice must be delivered to, or mailed and received at, the principal executive offices of the Corporation not less than ninety (90) days nor more than one hundred twenty (120) days prior to the one-year anniversary of the preceding year’s annual meeting; provided, however, that if no annual meeting was held in the preceding year, to be timely, a stockholder’s notice must be so delivered, or mailed and received, not earlier than the close of business on the one hundred and twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or, if later, the tenth (10th) day following the day on which public disclosure of the date of such annual meeting was first made by the Corporation; provided, further, that if the date of the annual meeting is more than thirty (30) days before or more than sixty (60) days after such anniversary date, to be timely, a stockholder’s notice must be so delivered, or mailed and received, not later than the ninetieth (90th) day prior to such annual meeting or, if later, the tenth (10th) day following the day on which public disclosure of the date of such annual meeting was first made by the Corporation (such notice within such time periods, “Timely Notice”). In no event shall any adjournment or postponement of an annual meeting or the announcement thereof commence a new time period for the giving of Timely Notice as described above.

(c) To be in proper form for purposes of this Section 2.4, a stockholder’s notice to the Secretary of the Corporation shall set forth:

(i) As to each Proposing Person (as defined below), (A) the name and address of such Proposing Person (including, if applicable, the name and address that appear on the Corporation’s books and records); and (B) the class or series and number of shares of the Corporation that are, directly or indirectly, owned of record or beneficially owned (within the meaning of Rule 13d-3 under the Exchange Act) by such Proposing Person, except that such Proposing Person shall in all events be deemed to beneficially own any shares of any class or series of the Corporation as to which such Proposing Person has a right to acquire beneficial ownership at any time in the future (the disclosures to be made pursuant to the foregoing clauses (A) and (B) are referred to as “Stockholder Information”);

(ii) As to each Proposing Person, (A) the full notional amount of any securities that, directly or indirectly, underlie any “derivative security” (as such term is defined in Rule 16a-1(c) under the Exchange Act) that constitutes a “call equivalent position” (as such term is defined in Rule 16a-1(b) under the Exchange Act) (“Synthetic Equity Position”) and that is, directly or indirectly, held or maintained by such Proposing Person with respect to any shares of any class or series of shares of the Corporation; provided that, for the purposes of the definition of “Synthetic Equity Position,” the term “derivative security” shall also include any security or instrument that would not otherwise constitute a “derivative security” as a result of any feature that would make any conversion, exercise or similar right or privilege of such security or instrument becoming determinable only at some future date or upon the happening of a future occurrence, in which case the determination of the amount of securities into which such security or instrument would be convertible or exercisable shall be made assuming that such security or instrument is immediately convertible or exercisable at the time of such determination; and, provided, further, that any Proposing Person satisfying the requirements of Rule 13d-1(b)(1) under the Exchange Act (other than a Proposing Person that so satisfies Rule 13d-1(b)(1) under the Exchange Act solely by reason of Rule 13d-1(b)(1)(ii)(E)) shall not be deemed to hold or maintain the notional amount of any securities that underlie a Synthetic Equity Position held by such Proposing Person as a hedge with respect to a bona fide derivatives trade or position of such Proposing Person arising in the ordinary course of such Proposing Person’s business as a derivatives dealer, (B) any rights to dividends on the shares of any class or series of shares of the Corporation owned beneficially by such Proposing Person that are separated or separable from the underlying shares of the Corporation, (C) any material pending or threatened Proceeding in which

such Proposing Person is a party or material participant involving the Corporation or any of its officers or directors, or any affiliate of the Corporation, (D) any other material relationship between such Proposing Person, on the one hand, and the Corporation or any affiliate of the Corporation, on the other hand, (E) any direct or indirect material interest in any material contract or agreement of such Proposing Person with the Corporation or any affiliate of the Corporation (including, in any such case, any employment agreement, collective bargaining agreement or consulting agreement), (F) a representation that such Proposing Person intends or is part of a group that intends to deliver a proxy statement or form of proxy to holders of at least the percentage of the Corporation’s outstanding capital stock required to approve or adopt the proposal or otherwise solicit proxies from stockholders in support of such proposal and (G) any other information relating to such Proposing Person that would be required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies or consents by such Proposing Person in support of the business proposed to be brought before the meeting pursuant to Section 14(a) of the Exchange Act (the disclosures to be made pursuant to the foregoing clauses (A) through (G) are referred to as “Disclosable Interests”); provided, however, that Disclosable Interests shall not include any such disclosures with respect to the ordinary course business activities of any broker, dealer, commercial bank, trust company or other nominee who is a Proposing Person solely as a result of being the stockholder directed to prepare and submit the notice required by these bylaws on behalf of a beneficial owner; and

(iii) As to each item of business that the stockholder proposes to bring before the annual meeting, (A) a brief description of the business desired to be brought before the annual meeting, the reasons for conducting such business at the annual meeting and any material interest in such business of each Proposing Person, (B) the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the bylaws, the language of the proposed amendment), and (C) a reasonably detailed description of all agreements, arrangements and understandings (x) between or among any of the Proposing Persons or (y) between or among any Proposing Person and any other person or entity (including their names) in connection with the proposal of such business by such stockholder; and (D) any other information relating to such item of business that would be required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies in support of the business proposed to be brought before the meeting pursuant to Section 14(a) of the Exchange Act; provided, however, that the disclosures required by this Section 2.4(c)(iii) shall not include any disclosures with respect to any broker, dealer, commercial bank, trust company or other nominee who is a Proposing Person solely as a result of being the stockholder directed to prepare and submit the notice required by these bylaws on behalf of a beneficial owner.

For purposes of this Section 2.4, the term “Proposing Person” shall mean (i) the stockholder providing the notice of business proposed to be brought before an annual meeting, (ii) the beneficial owner or beneficial owners, if different, on whose behalf the notice of the business proposed to be brought before the annual meeting is made, and (iii) any participant (as defined in paragraphs (a)(ii)-(vi) of Instruction 3 to Item 4 of Schedule 14A) with such stockholder in such solicitation.

(d) A Proposing Person shall update and supplement its notice to the Corporation of its intent to propose business at an annual meeting, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 2.4 shall be true and correct as of the record date for stockholders entitled to vote at the meeting and as of the date that is ten (10) business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary of the Corporation at the principal executive offices of the Corporation not later than five (5) business days after the record date for stockholders entitled to vote at the meeting (in the case of the update and supplement required to be made as of such record date), and not later than eight (8) business days prior to the date for the meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the meeting has been adjourned or postponed) (in the case of the update and supplement required to be made as of ten (10) business days prior to the meeting or any adjournment or postponement thereof). For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any notice provided by a stockholder, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any proposal or to submit any new proposal, including by changing or adding matters, business or resolutions proposed to be brought before a meeting of the stockholders.

For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any notice provided by a stockholder, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any nomination or to submit any new nomination.

Annex C-5

Table of Contents

(g) The Board may also require any proposed candidate for nomination as a Director to furnish such other information as may reasonably be requested by the Board in writing prior to the meeting of stockholders at which such candidate’s nomination is to be acted upon in order for the Board to determine the eligibility of such candidate for nomination to be an independent director of the Corporation in accordance with the Corporation’s corporate governance guidelines.

(h) A candidate for nomination as a director shall further update and supplement the materials delivered pursuant to this Section 2.5, if necessary, so that the information provided or required to be provided pursuant to this Section 2.5 shall be true and correct as of the record date for stockholders entitled to vote at the meeting and as of the date that is ten (10) business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary of the Corporation at the principal executive offices of the Corporation (or any other office specified by the Corporation in any public announcement) not later than five (5) business days after the record date for stockholders entitled to vote at the meeting (in the case of the update and supplement required to be made as of such record date), and not later than eight (8) business days prior to the date for the meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the meeting has been adjourned or postponed) (in the case of the update and supplement required to be made as of ten (10) business days prior to the meeting or any adjournment or postponement thereof). For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any notice provided by a stockholder, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any proposal or to submit any new proposal, including by changing or adding nominees, matters, business or resolutions proposed to be brought before a meeting of the stockholders.

(i) No candidate shall be eligible for nomination as a director of the Corporation unless such candidate for nomination and the Nominating Person seeking to place such candidate’s name in nomination has complied with this Section 2.5.

At any adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than thirty (30) days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the Board shall fix as the record date for determining stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such meeting as of the record date so fixed for notice of such adjourned meeting.

2.9 Conduct of Business.

The date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting by the person presiding over the meeting. The Board may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the Board, the person presiding over any meeting of stockholders shall have the right and authority to convene and (for any or no reason) to recess and/or adjourn the meeting, to prescribe such rules, regulations and procedures (which need not be in writing) and to do all such acts as, in the judgment of such presiding person, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board or prescribed by the person presiding over the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present (including, without limitation, rules and procedures for removal of disruptive persons from the meeting); (iii) limitations on attendance at or participation in the meeting to stockholders entitled to vote at the meeting, their duly authorized and constituted proxies or such other persons as the person presiding over the meeting shall determine; (iv) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (v) limitations on the time allotted to questions or comments by participants.

Except as otherwise provided by the Certificate of Incorporation, at all duly called or convened meetings of stockholders at which a quorum is present, for the election of directors, a plurality of the votes cast shall be sufficient to elect a director. Except as otherwise provided by the Certificate of Incorporation, these bylaws, the rules or regulations of any stock exchange applicable to the Corporation, or applicable law or pursuant to any regulation applicable to the Corporation or its securities, each other matter presented to the stockholders at a duly called or convened meeting at which a quorum is present shall be decided by the affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on such matter.

2.11 Record Date for Stockholder Meetings and Other Purposes.

In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall, unless otherwise required by law, not be more than sixty (60) days nor less than ten (10) days before the date of such meeting. If the Board so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the close of business on the next day preceding the day on which notice is first given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting; and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of capital stock, or for the purposes of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than sixty (60) days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

2.12 Proxies.

Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy authorized by an instrument in writing or by a transmission permitted by law filed in accordance with the procedure established for the meeting, but no such proxy shall be voted or acted upon after three (3) years from its date, unless the proxy provides for a longer period. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the provisions of Section 212 of the DGCL. A proxy may be in the form of an electronic transmission which sets forth or is submitted with information from which it can be determined that the transmission was authorized by the stockholder.

Annex C-8

2.13 List of Stockholders Entitled to Vote.

The Corporation shall prepare, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting (provided, however, that if the record date for determining the stockholders entitled to vote is less than ten (10) days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth (10th) day before the meeting date), arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. The Corporation shall not be required to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least ten (10) days prior to the meeting: (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours, at the Corporation’s principal executive office. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. Such list shall presumptively determine the identity of the stockholders entitled to vote at the meeting and the number of shares held by each of them. Except as otherwise provided by law, the stock ledger shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 2.13 or to vote in person or by proxy at any meeting of stockholders.

2.14 Inspectors of Election.

Before any meeting of stockholders, the Corporation shall appoint an inspector or inspectors of election to act at the meeting or its adjournment and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If any person appointed as inspector or any alternate fails to appear or fails or refuses to act, then the person presiding over the meeting shall appoint a person to fill that vacancy.

Such inspectors shall:

(i) determine the number of shares outstanding and the voting power of each, the number of shares represented at the meeting and the validity of any proxies and ballots;

(ii) count all votes or ballots;

(iii) count and tabulate all votes;

(iv) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspector(s); and

(v) certify its or their determination of the number of shares represented at the meeting and its or their count of all votes and ballots.

Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath faithfully to execute the duties of inspection with strict impartiality and according to the best of such inspector’s ability. Any report or certificate made by the inspectors of election is prima facie evidence of the facts stated therein. The inspectors of election may appoint such persons to assist them in performing their duties as they determine.

2.15 Delivery to the Corporation.

Whenever this Article II requires one or more persons (including a record or beneficial owner of stock) to deliver a document or information to the Corporation or any officer, employee or agent thereof (including any notice, request, questionnaire, revocation, representation or other document or agreement), such document or information shall be in writing exclusively (and not in an electronic transmission) and shall be delivered exclusively by hand (including, without limitation, overnight courier service) or by certified or registered mail, return receipt requested, and the Corporation shall not be required to accept delivery of any document not in such written form or so delivered. For the avoidance of doubt, the Corporation expressly opts out of Section 116 of the DGCL with respect to the delivery of information and documents to the Corporation required by this Article II.

Unless otherwise restricted by the Certificate of Incorporation or these bylaws, any action required or permitted to be taken at any meeting of the Board, or of any committee thereof, may be taken without a meeting if all members of the Board or committee, as the case may be, consent thereto in writing or by electronic transmission. After an action is taken, the consent or consents relating thereto shall be filed with the minutes of the proceedings of the Board, or the committee thereof, in the same paper or electronic form as the minutes are maintained.

7.4 Lost Certificates.

Except as provided in this Section 7.4, no new certificates for shares shall be issued to replace a previously issued certificate unless the latter is surrendered to the Corporation and cancelled at the same time. The Corporation may issue a new certificate of stock or uncertificated shares in the place of any certificate theretofore issued by it, alleged to have been lost, stolen or destroyed, and the Corporation may require the owner of the lost, stolen or destroyed certificate, or such owner’s legal representative, to give the Corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate or uncertificated shares.

7.13 Waiver of Notice.

Whenever notice is required to be given under any provision of the DGCL, the Certificate of Incorporation or these bylaws, a written waiver, signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time of the event for which notice is to be given, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver of notice or any waiver by electronic transmission unless so required by the Certificate of Incorporation or these bylaws.

Article VIII — Notice

8.1 Delivery of Notice; Notice by Electronic Transmission.

Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Corporation under any provisions of the DGCL, the Certificate of Incorporation, or these bylaws may be given in writing directed to the stockholder’s mailing address (or by electronic transmission directed to the stockholder’s electronic mail address, as applicable) as it appears on the records of the Corporation and shall be given (1) if mailed, when the notice is deposited in the U.S. mail, postage prepaid, (2) if delivered by courier service, the earlier of when the notice is received or left at such stockholder’s address or (3) if given by electronic mail, when directed to such stockholder’s electronic mail address unless the stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail. A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Corporation.

Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Corporation under any provision of the DGCL, the Certificate of Incorporation or these bylaws shall be effective if given by a form of electronic transmission consented to by the stockholder to whom the notice is given. Any such consent shall be revocable by the stockholder by written notice or electronic transmission to the Corporation. Notwithstanding the provisions of this paragraph, the Corporation may give a notice by electronic mail in accordance with the first paragraph of this section without obtaining the consent required by this paragraph.

Any notice given pursuant to the preceding paragraph shall be deemed given:

(i) if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice;

(ii) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of (A) such posting and (B) the giving of such separate notice; and

(iii) if by any other form of electronic transmission, when directed to the stockholder.

Notwithstanding the foregoing, a notice may not be given by an electronic transmission from and after the time that (1) the Corporation is unable to deliver by such electronic transmission two (2) consecutive notices given by the Corporation and (2) such inability becomes known to the Secretary or an Assistant Secretary of the Corporation or to the transfer agent, or other person responsible for the giving of notice; provided, however, that the inadvertent failure to discover such inability shall not invalidate any meeting or other action.

An affidavit of the Secretary or an Assistant Secretary of the Corporation or of the transfer agent or other agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

Article IX — Indemnification

9.1 Indemnification of Directors and Officers.

The Corporation shall indemnify and hold harmless, to the fullest extent permitted by the DGCL as it presently exists or may hereafter be amended, any director or officer of the Corporation who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “Proceeding”) by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was a director or officer of the Corporation or, while serving as a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership (a “covered person”), joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys’ fees, judgments, fines ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred by such person in connection with any such Proceeding.

9.4 Determination; Claim.

If a claim for indemnification (following the final disposition of such Proceeding) under this Article IX- is not paid in full within sixty (60) days, or a claim for advancement of expenses under this Article IX- is not paid in full within thirty (30) days, after a written claim therefor has been received by the Corporation the covered person may thereafter (but not before) file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim to the fullest extent permitted by law.

This Letter Agreement may not be changed, amended, modified or waived (other than to correct a typographical error or error immaterial to the Company) as to any particular provision.

No party hereto may assign either this Letter Agreement or any of its rights, interests or obligations hereunder without the prior written consent of the other parties. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This Letter Agreement shall be binding on each Securityholder and each of its successors, heirs and assigns and permitted transferees. This Letter Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other person.

This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall be brought and enforced in any Delaware Chancery Court, and irrevocably submit to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum.

FURTHERMORE, NO PARTY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED.

Table of Contents

This Letter Agreement may be delivered via electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com or www.echosign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

If any term or other provision of this Letter Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other terms, conditions and provisions of this Letter Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Letter Agreement are not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Letter Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Letter Agreement be consummated as originally contemplated to the fullest extent possible.

This Letter Agreement shall automatically terminate upon the earlier of (i) the expiration of the Lock-Up Period, (ii) the closing of a liquidation, merger, stock exchange, reorganization or other similar transaction after the Closing that results in all of the public stockholders of the Company having the right to exchange their shares of Common Stock for cash securities or other property or (iii) the liquidation of the Company.

The parties hereto acknowledge that the rights of each party hereto to consummate the transactions contemplated hereby are unique and recognize and affirm that in the event of a breach of this Letter Agreement by any party hereto, money damages may be inadequate and the non-breaching parties may have no adequate remedy at law. Accordingly, the parties hereto agree that such non-breaching parties shall have the right, in addition to any other rights and remedies existing in their favor at law or in equity, to enforce their rights and the other party’s obligations hereunder not only by an action or actions for damages but also by an action or actions for specific performance, injunctive and/or other equitable relief (without posting of bond or other security), including any order, injunction or decree sought by any such non-breaching party to cause another party to perform its respective agreements and covenants contained in this Letter Agreement. Each party hereto further agrees that the only permitted objection that it may raise in response to any action for equitable relief is that it contests the existence of a breach or threatened breach of this Letter Agreement, and that no party hereto shall allege, and each party hereto hereby waives the defense, that there is an adequate remedy at law.

The liability of any Securityholder hereunder is several (and not joint). Notwithstanding any other provision of this Letter Agreement, in no event will any Securityholder be liable for any other Securityholder’s breach of such other Securityholder’s obligations under this Letter Agreement.

(i) Shelf Registration. Subject to Section 3(c), the Company agrees to file within thirty (30) days after the date of this Agreement, a shelf Registration Statement on Form S-1, or such other form under the Securities Act then available to the Company, providing for the resale of all Registrable Securities (determined as of two (2) business days prior to such filing) pursuant to Rule 415, from time to time (a “Shelf Registration Statement”). The Company shall use commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission as soon as practicable after the filing thereof. The Shelf Registration Statement shall provide for the resale from time to time, and pursuant to any method or combination of methods legally available (including, without limitation, an Underwritten Offering, a direct sale to purchasers or a sale through brokers or agents) to the Holders of any and all Registrable Securities. Following the filing of the Shelf Registration Statement, the Company shall use its commercially reasonable efforts to convert the Shelf Registration Statement on Form S-1 (and any Subsequent Shelf Registration) to a Registration Statement on Form S-3 as soon as practicable after the Company is eligible to use Form S-3.

(ii) Subsequent Shelf Registration. If any Shelf Registration Statement ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall, subject to Section 2(e), use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf Registration Statement to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf Registration Statement), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf Registration Statement in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf Registration Statement or file an additional registration statement as a Shelf Registration Statement (a “Subsequent Shelf Registration”) registering the resale of all Registrable Securities (determined as of two business days prior to such filing), and pursuant to any method or combination of methods legally available to, and requested by, any Holder named therein. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing

Annex H-4

Table of Contents

thereof (it being agreed that the Subsequent Shelf Registration shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form.

(iii) Additional Registrable Securities. In the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon request of a Holder that holds at least five percent (5.0%) of the Registrable Securities, shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, the Shelf Registration Statement (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing and such Shelf Registration Statement or Subsequent Shelf Registration shall be subject to the terms hereof; provided, however, that the Company shall only be required to cause such Registrable Securities to be so covered twice per calendar year.

(iv) Requests for Underwritten Shelf Takedowns. At any time and from time to time when an effective Shelf Registration Statement is on file with the Commission, any one or more Holders (any of the Holders being, in such case, a “Demanding Holder”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering that is registered pursuant to the Shelf Registration Statement (each, an “Underwritten Shelf Takedown”); provided in each case that the Company shall only be obligated to effect an Underwritten Offering if such offering shall include Registrable Securities proposed to be sold by the Demanding Holder(s) with a total offering price reasonably expected to exceed, in the aggregate, $25.0 million (the “Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. Promptly (but in any event within ten (10) days) after receipt of a request for Underwritten Shelf Takedown, the Company shall give written notice of the Underwritten Shelf Takedown to all other Holders. The Company shall have the right to select the underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the initial Demanding Holder’s prior approval (which shall not be unreasonably withheld, conditioned or delayed). The Holders may collectively demand no more than two (2) Underwritten Shelf Takedowns pursuant to this Section 2(a)(iv) in any 12-month period (the “Shelf Takedown Limit”). Notwithstanding anything to the contrary in this Agreement, the Company may effect any Underwritten Shelf Takedown pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such offering.

(v) Reduction of Underwritten Shelf Takedown. If, in connection with an Underwritten Offering that is effectuated for the account of stockholders of the Company, including pursuant to Section 2(a)(iv), in which Registrable Securities are included, the managing underwriters of such Underwritten Offering advise the Company in writing that, in their opinion and in consultation with the Company, the number of shares of Common Stock, including any Registrable Securities, requested to be included in such Underwritten Offering exceeds the number that can be sold in such Underwritten Offering and/or that the number of Registrable Securities proposed to be included in any such Underwritten Offering would adversely affect the price per share of the Company’s equity securities to be sold in such Underwritten Offering (such maximum number of securities or Registrable Securities, as applicable, the “Maximum Threshold”), then the number of shares of Common Stock to be included in such Underwritten Offering shall be allocated among the Holders and holders of Non-Holder Securities as follows: (A) first, the shares comprised of Registrable Securities, pro rata, based on the amount of such Common Stock initially requested to be included by the Holders or as such Holders may otherwise agree, that can be sold without exceeding the Maximum Threshold; (B) second, to the extent that the Maximum Threshold has not been reached under the foregoing clause (A), the shares of Common Stock of a Holder of the Company’s securities other than Registrable Securities (“Non-Holder Securities”) that either (1) the Company is obligated to include pursuant to written contractual rights entered into prior to or on the date hereof or (2) such other contractual rights governing the applicable Non-Holder Securities, pro rata, based on the amount of such Common Stock initially requested to be included by the holders of Non-Holder Securities or as such holders of Non-Holder Securities may otherwise agree, that can be sold without exceeding the Maximum Threshold; (C) third, to the extent that the Maximum Threshold has not been reached under the foregoing clause (A), Non-Holder Securities that the Company is obligated to include pursuant to written contractual rights entered into after the date

Annex H-5

Table of Contents

hereof that do not comply with clause (B)(2) above, that can be sold without exceeding the Maximum Threshold; and (D) fourth, to the extent that the Maximum Threshold has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Threshold.

(vi) Withdrawal. Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten Shelf Takedown, a majority-in-interest of the Demanding Holders initiating an Underwritten Shelf Takedown shall have the right to withdraw from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”) to the Company and the underwriter or underwriters (if any) of their intention to withdraw from such Underwritten Shelf Takedown; provided that any Holder may elect to have the Company continue an Underwritten Shelf Takedown if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown by the Holders. If withdrawn, a demand for an Underwritten Shelf Takedown shall constitute a demand for an Underwritten Shelf Takedown for purposes of Section 2(a)(iv), unless the Holder reimburses the Company for all Sale Expenses with respect to such Underwritten Shelf Takedown; provided that, if a Holder elects to continue an Underwritten Shelf Takedown pursuant to the proviso in the immediately preceding sentence, such Underwritten Shelf Takedown shall instead count as an Underwritten Shelf Takedown demanded by the Holders for purposes of Section 2(a)(iv). Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Holders that had elected to participate in such Underwritten Shelf Takedown. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Sale Expenses incurred in connection with a Underwritten Shelf Takedown prior to its withdrawal under this Section 2(a)(vi), other than if a Demanding Holder elects to pay such Sale Expenses pursuant to the second sentence of this Section 2(a)(vi).

(b) Piggyback Rights.

(i) Right to Piggyback. If the Company or any Holder proposes to conduct a registered offering of, or if the Company proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, an Underwritten Shelf Takedown pursuant to Section 2(a)(iv)), other than a Registration Statement (or any registered offering with respect thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan or (v) for a rights offering, then the Company shall give written notice of such proposed offering to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement or, in the case of an Underwritten Offering pursuant to a Shelf Registration Statement, the applicable “red herring” prospectus or prospectus supplement used for marketing such offering, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing underwriter or underwriters, if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to include in such registered offering such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such Registration, a “Piggyback Registration”). Subject to Section 2(b)(ii), the Company shall cause such Registrable Securities to be included in such Piggyback Registration and, if applicable, shall use its commercially reasonable efforts to cause the managing underwriter or underwriters of such Piggyback Registration to permit the Registrable Securities requested by the Holders pursuant to this Section 2(b)(i) to be included therein on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. The inclusion of any Holder’s Registrable Securities in a Piggyback Registration shall be subject to such Holder’s agreement to enter into an underwriting agreement in customary form with the underwriter(s) selected for such Underwritten Offering by the Company.

(ii) Reduction of Offering. If the managing underwriter or underwriters in an Underwritten Offering that is to be a Piggyback Registration advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of shares of Common Stock or other equity securities that the Company desires to sell, taken together with (i) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been demanded pursuant to separate written

Annex H-6

Table of Contents

contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2(b), and (iii) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Threshold, then:

(A) If the Registration or registered offering is initiated by the Company primarily for its own account, the number of shares of Common Stock to be included in such Underwritten Offering shall be allocated as follows: (A) first, the shares of Common Stock or other securities to be sold by the Company; (B) second, to the extent that the Maximum Threshold has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities hereunder; and (C) third, to the extent that the Maximum Threshold has not been reached under the foregoing clauses (A) and (B), Non-Holder Securities that the Company is obligated to include pursuant to separate written contractual rights that can be sold without exceeding the Maximum Threshold;

(B) If the Registration or registered offering is initiated for the account of stockholders of the Company other than the Holders of Registrable Securities, the number of shares of Common Stock to be included in such Underwritten Offering shall be allocated as follows: (A) first, the shares comprised of Registrable Securities and the Non-Holder Securities that either (1) the Company is obligated to include pursuant to written contractual rights entered into prior to or on the date hereof or (2) such other contractual rights governing the applicable Non-Holder Securities provide that the Holder’s participation rights in such offering are pari passu with respect to registration cutbacks in the same fashion as set forth in this clause (A), pro rata, based on the amount of such Common Stock initially requested to be included by the Holders or holders of Non-Holder Securities or as such Holder or holders of Non-Holder Securities may otherwise agree, that can be sold without exceeding the Maximum Threshold; (B) second, to the extent that the Maximum Threshold has not been reached under the foregoing clause (A), Non-Holder Securities that the Company is obligated to include pursuant to written contractual rights entered into after the date hereof that do not comply with clause (A)(2) above, that can be sold without exceeding the Maximum Threshold; and (C) third, to the extent that the Maximum Threshold has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Threshold; and

(C) If the Registration or registered offering is pursuant to a request by Holder(s) of Registrable Securities pursuant to Section 2(a)(iv), then the Company shall include in any such Registration or registered offering securities pursuant to Section 2(a)(v).

(iii) Withdrawal. Any Holder of Registrable Securities (other than a Demanding Holder, whose right to withdrawal from an Underwritten Shelf Takedown, and related obligations, shall be governed by Section 2(a)(vi)) shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the underwriter or underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration or, in the case of a Piggyback Registration pursuant to a Shelf Registration Statement, the filing of the applicable “red herring” prospectus or prospectus supplement with respect to such Piggyback Registration used for marketing such transaction. The Company (whether on its own determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration (which, in no circumstance, shall include the Shelf Registration Statement) at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement (other than Section 2(a)(vi)), the Company shall be responsible for the Sale Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2(b)(iii).

(iv) Unlimited Piggyback Registration Rights. For purposes of clarity, subject to Section 2(a)(vi), any Piggyback Registration effected pursuant to Section 2(b) shall not be counted as a demand for an Underwritten Shelf Takedown under Section 2(a)(iv).

(i) Block Trades. Notwithstanding the foregoing, at any time and from time to time when an effective Shelf Registration Statement is on file with the Commission, if a Demanding Holder wishes to engage in (A) a Block Trade or (B) an “at the market” or similar registered offering through a broker, sales agent or distribution agent, whether as agent or principal (an “Other Coordinated Offering”), in each case with a total offering price reasonably expected to exceed, in the aggregate, either (x) $25.0 million or (y) all remaining Registrable Securities held by the Demanding Holder, then notwithstanding the time periods provided for in Section 2(a)(iv), such Demanding Holder shall notify the Company of the Block Trade or Other Coordinated Offering at least five (5) business days prior to the day such offering is to commence and the Company shall as expeditiously as possible use its commercially reasonable efforts to facilitate such Block Trade or Other Coordinated Offering; provided that the Demanding Holders representing a majority of the Registrable Securities wishing to engage in the Block Trade or Other Coordinated Offering shall use commercially reasonable efforts to work with the Company and any underwriters or placement agents or sales agents prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the Block Trade or Other Coordinated Offering; provided further that in the case of such underwritten Block Trade or Other Coordinated Offering, only such Holder shall have a right to notice of and to participate in such offering.

(ii) Withdrawal. Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block Trade or Other Coordinated Offering, a majority-in-interest of the Demanding Holders initiating such Block Trade or Other Coordinated Offering shall have the right to submit a Withdrawal Notice to the Company and the underwriter or underwriters or placement agents or sales agents (if any) of their intention to withdraw from such Block Trade or Other Coordinated Offering. If withdrawn, a demand for a Block Trade or Other Coordinated Offering shall constitute a demand for an Underwritten Shelf Takedown, unless the Holder reimburses the Company for all Sale Expenses with respect to such Block Trade or Other Coordinated Offering.

(iii) Cap on Block Trades and Other Coordinated Offerings. Any Registration effected pursuant to this Section 2(c) shall be deemed an Underwritten Shelf Takedown and counted towards the Shelf Takedown Limit. Notwithstanding anything to the contrary in this Agreement, Section 2(b) shall not apply to a Block Trade or Other Coordinated Offering initiated by a Demanding Holder pursuant to this Agreement.

(d) Continued Effectiveness. The Company shall use commercially reasonable efforts to keep any Registration Statement continuously effective for the period beginning on the date on which such Registration Statement is declared effective and ending on the date that all of Registrable Securities registered under the Registration Statement cease to be Registrable Securities. During the period that such Registration Statement is effective, the Company shall use commercially reasonable efforts to supplement or make amendments to the Registration Statement, if required by the Securities Act or if reasonably requested by Holder (whether or not required by the form on which the securities are being registered), including to reflect any specific plan of distribution or method of sale, and shall use its commercially reasonable efforts to have such supplements and amendments declared effective, if required, as soon as practicable after filing.

(e) Suspension Period; Blackout Period.

(i) Misstatement. Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed (any such period, a “Suspension Period”).

(ii) Other Suspension. Notwithstanding any provision of this Agreement to the contrary, if the Board determines in good faith that any use of a Registration Statement or Prospectus hereunder involving Registrable Securities would (i) reasonably be expected to, in the good faith judgment of the majority of the Board, after consultation with counsel to the Company, materially impede, delay or interfere with, or require premature disclosure of, any material financing, offering, acquisition, disposition, merger, corporate reorganization, segment reclassification or discontinuance of operations that is required to be reflected in pro forma or restated financial statements that amends historical financial statements of the Company, or other significant transaction or any negotiations, discussions or

Annex H-8

Table of Contents

pending proposals with respect thereto, involving the Company or any of its subsidiaries; (ii) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control; or (iii) require, after consultation with counsel to the Company, the disclosure of material non-public information, the disclosure of which would (x) not be required to be made if a Registration Statement were not being used and (y) reasonably be expected to materially and adversely affect the Company, then the Company shall be entitled to suspend, for not more than sixty (60) consecutive days (any such period, a “Blackout Period”), but in no event (A) more than three (3) times in any consecutive twelve (12) month period (which periods may be successive) and (B) for more than an aggregate of one hundred twenty (120) days in any rolling twelve (12) month period, commencing on the date of this Agreement, the use of any Registration Statement or Prospectus and shall not be required to amend or supplement the Registration Statement, any related Prospectus or any document incorporated therein by reference. The Company promptly will give written notice of any such Blackout Period to the Holders.

(f) Sale Expenses. All Sale Expenses of any Holder incurred in connection with Section 2 and Section 3 shall be borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as underwriters’ or agents’ commissions and discounts, brokerage fees, underwriter marketing costs and, other than as set forth in the definition of “Sale Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders.

(g) Market Stand-Off. In connection with any Underwritten Offering of equity securities of the Company (other than a Block Trade or Other Coordinated Offering), each Holder that holds greater than five percent (5%) of the outstanding Common Stock that is given an opportunity to participate in the Underwritten Offering pursuant to the terms of this Agreement and participates in such Underwritten Offering and each Holder that is an executive officer or director of the Company agrees that it shall not transfer any shares of Common Stock or other equity securities of the Company (other than those included in such offering pursuant to this Agreement), without the prior written consent of the Company, during the 90-day period beginning on the date of pricing of such offering or such shorter period during which the Company agrees not to conduct an underwritten primary offering of Common Stock, except in the event the underwriters managing the offering otherwise agree by written consent. Each Holder that holds greater than five percent (5%) of the outstanding Common Stock and participates in such Underwritten Offering or is an executive officer or director of the Company agrees to execute a customary lock-up agreement in favor of the underwriters to such effect (in each case on substantially the same terms and conditions as all such Holders).

3. PROCEDURES

(a) In connection with the filing of any Registration Statement or sale of Registrable Securities as provided in this Agreement, the Company shall use commercially reasonable efforts to, as expeditiously as reasonably practicable:

(i) notify promptly the Holders and, if requested by a Holder, confirm such advice in writing promptly at the address determined in accordance with Section 6(d), (A) of the issuance by the Commission or any state securities authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose, (B) if, between the effective date of a Registration Statement and the closing of any sale of Registrable Securities covered thereby, the representations and warranties of the Company contained in any underwriting agreement, securities sales agreement or other similar agreement, if any, relating to the offering cease to be true and correct in all material respects, (C) of the happening of any event or the discovery of any facts during the period a Registration Statement is effective as a result of which such Registration Statement or any document incorporated by reference therein contains any Misstatement or alleged Misstatement (which information shall be accompanied by an instruction to suspend the use of the Registration Statement and the prospectus until the requisite changes have been made), (D) of the receipt by the Company of any notification with respect to the suspension of the qualification of Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose and (E) of the filing of a post-effective amendment to such Registration Statement;

(ii) furnish each Holder’s legal counsel, if any, copies of any comment letters relating to such Holder received from the Commission or any other request by the Commission or any state securities authority for amendments or supplements to a Registration Statement and prospectus or for additional information relating to such Holder;

(iii) use commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement as promptly as practicable;

Annex H-9

Table of Contents

(iv) upon the occurrence of any event or the discovery of any facts, as contemplated by Section 3(a)(i)(C), as promptly as practicable after the occurrence of such an event, use its commercially reasonable efforts to prepare a supplement or post-effective amendment to the Registration Statement or the related prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Registrable Securities, such prospectus will not contain at the time of such delivery any Misstatement or alleged Misstatement. At such time as such public disclosure is otherwise made or the Company determines that such disclosure is not necessary, in each case to correct any Misstatement, the Company agrees promptly to notify the Holders of such determination and to furnish any Holder such number of copies of the prospectus as amended or supplemented, as such Holder may reasonably request;

(v) enter into agreements in customary form (including underwriting agreements) and take all other reasonable and customary appropriate actions in order to expedite or facilitate the disposition of such Registrable Securities regardless of whether an underwriting agreement is entered into and regardless of whether the registration is an underwritten registration, including:

(A) for an Underwritten Offering, making such representations and warranties to the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in similar Underwritten Offerings as may be reasonably requested by them;

(B) for an Underwritten Offering, obtaining opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to any managing underwriter(s) and their counsel) addressed to the underwriters, if any, covering the matters customarily covered in opinions requested in Underwritten Offerings and such other matters as may be reasonably requested by the underwriter(s);

(C) for an Underwritten Offering, obtaining “comfort” letters and updates thereof from the Company’s independent registered public accounting firm (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial statements are, or are required to be, included in the Registration Statement) addressed to the underwriter(s), such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters to underwriters in connection with similar Underwritten Offerings;

(D) entering into a securities sales agreement with the Holder(s) and an agent of Holder(s) providing for, among other things, the appointment of such agent for the Holder(s) for the purpose of soliciting purchases of Registrable Securities, which agreement shall be in form, substance and scope customary for similar offerings;

(E) if an underwriting agreement is entered into, using commercially reasonable efforts to cause the same to set forth indemnification provisions and procedures substantially similar to the indemnification provisions and procedures set forth in Section 4 with respect to the underwriters or, at the request of any underwriters, in the form customarily provided to underwriters in similar types of transactions; and

(F) delivering such documents and certificates as may be reasonably requested and as are customarily delivered in similar offerings to the managing underwriters, if any;

(vi) make available for inspection by any underwriter participating in any disposition pursuant to a Registration Statement, the Holders’ legal counsel and any accountant retained by a Holder, all financial and other records, pertinent corporate documents and properties or assets of the Company reasonably requested by any such Persons (excluding all trade secrets and other proprietary or privileged information) to the extent required for the offering, and cause the respective officers, directors, employees, and any other agents of the Company to supply all information reasonably requested by any such representative, underwriter, counsel or accountant in connection with a Registration Statement, and make such representatives of the Company available for discussion of such documents as shall be reasonably requested by the Company; provided, however, that the Holders’ legal counsel, if any, and the representatives of any underwriters will use commercially reasonable efforts, to the extent reasonably practicable, to coordinate the foregoing inspection and information gathering and to not unreasonably disrupt v Company’s business operations;

Annex H-10

Table of Contents

(vii) a reasonable time prior to filing any Registration Statement, any prospectus forming a part thereof, any amendment to such Registration Statement, or amendment or supplement to such prospectus, provide copies of such document to the underwriter(s) of an Underwritten Offering of Registrable Securities; within five (5) Business Days after the filing of any Registration Statement, provide copies of such Registration Statement to any Holder’s legal counsel upon request; consider in good faith making any changes requested and make such changes in any of the foregoing documents as are legally required prior to the filing thereof, or in the case of changes received from any Holder’s legal counsel by filing an amendment or supplement thereto, as the underwriter or underwriters, or in the case of changes received from a Holder’s legal counsel relating to such Holder or the plan of distribution of Registrable Securities, as such Holder’s legal counsel reasonably requests prior to the effectiveness of the applicable Registration Statement; not file any such document in a form to which any underwriter shall not have previously been advised and furnished a copy of; not include in any amendment or supplement to such documents any information about any Holders or any change to the plan of distribution of Registrable Securities that would limit the method of distribution of Registrable Securities unless such Holder’s legal counsel has been advised in advance and has approved such information or change (it being understood that any Holder that determines not to approve the inclusion of such change or information that has been specifically requested by the Commission will not have its Registrable Securities included in such Registration Statement and the Company shall not be in breach of this Agreement as a result of such exclusion); and reasonably during normal business hours make the representatives of the Company available for discussion of such document as shall be reasonably requested by the Holders’ legal counsel, if any, on behalf of a Holder, Holder’s legal counsel or any underwriter;

(viii) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission and make available to its securityholders, as soon as reasonably practicable, an earnings statement covering at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement, which shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

(ix) cooperate and assist in any filings required to be made with FINRA and in the performance of any due diligence investigation by any underwriter and its counsel (including any “qualified independent underwriter” that is required to be retained in accordance with the rules and regulations of FINRA);

(x) if Registrable Securities are to be sold in an Underwritten Offering, include in the registration statement to be used all such information as may be reasonably requested by the underwriters for the marketing and sale of such Registrable Securities; and

(xi) in connection with an Underwritten Offering, use its reasonable efforts to cause the appropriate officers of the Company to (A) prepare and make presentations at any “road shows” and before analysts and (B) cooperate as reasonably requested by the underwriters in the offering, marketing or selling of Registrable Securities.

(b) Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event or the discovery of any facts of the type described in Section 3(a)(i), each Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Registration Statement relating to such Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(a)(i), and, if so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all copies in such Holder’s possession, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities at the time of receipt of such notice.

(c) The Company may (as a condition to any Holder’s participation in an Underwritten Offering or Holder’s inclusion in a Registration Statement) require each Holder to furnish to the Company such information regarding the Holder and the proposed distribution by the Holder as the Company may from time to time reasonably request in writing.

4. INDEMNIFICATION

(a) Indemnification by The Company. The Company agrees to indemnify and hold harmless each Holder, and the respective officers, directors, partners, employees, representatives and agents of each Holder, and each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) a Holder, as follows:

(i) against any and all loss, liability, claim, damage, judgment, actions, other liabilities and expenses whatsoever (the “Liabilities”), as incurred, arising out of any Misstatement contained in any Registration Statement (or any amendment or supplement thereto) pursuant to which Registrable Securities were registered under the Securities Act at the time such Registration Statement became effective, including all documents incorporated therein by reference;

(ii) against any and all Liabilities, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by any indemnified party), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under Section 4(a)(i) or Section 4(a)(ii); provided, however, that the indemnity obligations in this Section 4(a) shall not apply to any Liabilities (A) to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Holder with the understanding that such information will be used in a Registration Statement (or any amendment thereto) or any prospectus (or any amendment or supplement thereto) or (B) to the extent they arise from the use of any Registration Statement during any Suspension Period or Blackout Period.

(b) Indemnification by the Holders. The Holders agree, severally and not jointly, to indemnify and hold harmless the Company, and each of its respective officers, directors, partners, employees, representatives and agents and any person controlling the Company, against any and all Liabilities described in the indemnity contained in Section 4(a), as incurred, but only with respect to Misstatements or alleged Misstatements made in the Registration Statement (or any amendment thereto) or any prospectus included therein (or any amendment or supplement thereto) in reliance upon and in conformity with written information with respect to such Holder furnished to the Company by such Holder with the understanding that such information will be used in the Registration Statement (or any amendment thereto) or such prospectus (or any amendment or supplement thereto); provided, however, that Holder shall be liable for any claims hereunder in excess of the amount of net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement.

(c) Notices of Claims, etc. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action or proceeding commenced against it in respect of which indemnity may be sought hereunder, but failure so to notify an indemnifying party shall not relieve such indemnifying party from any Liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any Liability which it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party or parties be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 4 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all Liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

Annex H-12

Table of Contents

(d) Contribution. If the indemnification provided for in this Section 4 is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any Liabilities referred to therein, then each indemnifying party shall contribute to the aggregate amount of such Liabilities incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative fault of the Company, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions which resulted in such Liabilities, as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and the Holders, on the other hand, shall be determined by reference to, among other things, whether any Misstatement or alleged Misstatements relates to information supplied by the Company or a Holder and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 4. The aggregate amount of Liabilities incurred by an indemnified party and referred to above in this Section 4 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 4, each Person, if any, who controls a Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Holder, and each director of the Company, and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company.

5. TERMINATION. The rights of the Holders under this Agreement shall terminate in accordance with the terms of this Agreement and in any event, upon the date that each such party holds no Registrable Securities (the “Termination Date”). Notwithstanding the foregoing, the obligations of the parties under Section 4 of this Agreement shall remain in full force and effect following such time.

6. MISCELLANEOUS

(a) Covenants Relating To Rule 144. With a view to making available to the Holders the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration statement, if the Shares of the Company are registered under the Exchange Act, the Company agrees to: (A) file with the SEC all reports and other documents required of the Company under Section 13(a) or 15(d) of the Exchange Act (at any time after it has become subject to such reporting requirements); and (B) furnish to any Holder, so long as the Holder owns any Registrable Securities, upon request, (i) a written statement by the Company that it has complied with the reporting requirements of the Exchange Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to a registration statement (at any time after it so qualifies) and (ii) such other information as may be reasonably requested by any Holder in order to avail itself of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.

(b) No Inconsistent Agreements. The Company has not entered into, and the Company will not after the date of this Agreement enter into, any agreement which is inconsistent with the rights granted to the Holders pursuant to this Agreement or otherwise conflicts with the provisions of this Agreement.

(c) Amendment; Modification; Waiver. This Agreement may be amended, modified or supplemented at any time only by written agreement of the Company and the Holders owning a majority in voting power of the Registrable Securities; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof shall also require the written consent of XPDI Sponsor II LLC (the “Sponsor”) for so long as the Sponsor holds at least five percent (5%) of the outstanding shares of Common Stock of the Company. The conditions to the respective obligations of each of the parties to this Agreement to consummate the transactions contemplated hereby are for the sole benefit of such party and may be waived by such party in whole or in part to the extent permitted by applicable law; provided, however, that any such waiver shall only be effective if made in writing and executed by the party against whom the waiver is to be effective. No failure or delay by any party to this Agreement in exercising any right, power or privilege hereunder or under applicable law shall operate as a waiver of such rights and, except as otherwise expressly provided

Annex H-13

Table of Contents

herein, no single or partial exercise thereof shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

(d) Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given (a) when delivered in person or, by e-mail (return receipt requested), (b) on the next Business Day when sent by overnight courier or (c) on the second succeeding Business Day when sent by registered or certified mail (postage prepaid, return receipt requested) to the respective parties to this Agreement at the following addresses (or at such other address for a party to this Agreement as shall be specified by like notice):

If to a Holder, to the most current address given by such Holder to the Company by means of a notice given in accordance with the provisions of this Section 6(d).

If to the Company to:

Montana Technologies Corporation

Ronan, MT 59864
Attention: Matt Jore
E-mail: matt.jore@mt.energy

with a copy (which shall not constitute notice) to:

		Latham & Watkins LLP 811 Main Street, Suite 3700 Houston, Texas 77002
		Attention:		Ryan J. Maierson John M. Greer
		E-mail:		ryan.maierson@lw.com john.greer@lw.com

All such notices, requests, demands, waivers and communications shall be deemed received upon (i) actual receipt thereof by the addressee, or (ii) actual delivery thereof to the appropriate address.

(e) Binding Agreement; Assignment. This Agreement and all of the provisions hereof shall be binding upon and shall inure to the benefit of the parties to this Agreement and their respective successors and permitted assigns. Other than with respect to registration rights provided hereunder which may be assigned by a Holder to its Affiliates, no party to this Agreement may assign its rights under this Agreement without the prior written consent of the other parties, and any attempted or purported assignment or delegation in violation of this Section 6(e) shall be null and void.

(f) Specific Performance. The parties to this Agreement acknowledge that the rights of each party hereto to consummate the transactions contemplated hereby are unique and recognize and affirm that in the event of a breach of this Agreement by any party hereto, money damages may be inadequate and the non-breaching party may have no adequate remedy at law. Accordingly, the parties to this Agreement agree that such non-breaching party shall have the right, in addition to any other rights and remedies existing in their favor at law or in equity, to enforce its rights and the other parties’ obligations hereunder not only by an action or actions for damages but also by an action or actions for specific performance, injunctive and/or other equitable relief (without posting of bond or other security), including any order, injunction or decree sought by such non-breaching party to cause the other parties hereto to perform their respective agreements and covenants contained in this Agreement. Each party to this Agreement further agrees that the only permitted objection that it may raise in response to any action for equitable relief is that it contests the existence of a breach or threatened breach of this Agreement, and that no party to this Agreement shall allege, and each party to this Agreement hereby waives the defense, that there is an adequate remedy at law.

(g) Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by e-mail shall be as effective as delivery of a manually executed counterpart of the Agreement.

Table of Contents

(h) Headings. The article and section headings contained in this Agreement are exclusively for the purpose of reference, are not part of the agreement of the parties to this Agreement and shall not in any way affect the meaning or interpretation of this Agreement.

(i) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware (regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof) as to all matters, including matters of validity, construction, effect, performance and remedies.

(j) Consent to Jurisdiction, etc.; WAIVER OF JURY TRIAL. Each party to this Agreement irrevocably agrees that any action, suit or proceeding between or among the parties to this Agreement arising in connection with any disagreement, dispute, controversy or claim arising out of or relating to this Agreement or any related document (each, a “Legal Dispute”) shall be brought exclusively in the courts of the State of Delaware; provided that if subject matter jurisdiction over the Legal Dispute is vested exclusively in the United States federal courts, such Legal Dispute shall be heard in the United States District Court for the District of Delaware. Each party to this Agreement hereby irrevocably and unconditionally submits to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding that is brought in any such court has been brought in an inconvenient forum. During the period a Legal Dispute that is filed in accordance with this Section 6(j) is pending before a court, all actions, suits or proceedings with respect to such Legal Dispute or any other Legal Dispute, including any counterclaim, cross-claim or interpleader, shall be subject to the exclusive jurisdiction of such court. Each party to this Agreement may bring such Legal Dispute only if he, she or it hereby waives, and shall not assert as a defense in any Legal Dispute, that (a) such party is not personally subject to the jurisdiction of the above-named courts for any reason, (b) such action, suit or proceeding may not be brought or is not maintainable in such court, (c) such party’s property is exempt or immune from execution, (d) such action, suit or proceeding is brought in an inconvenient forum, or (e) the venue of such action, suit or proceeding is improper. A final judgment in any action, suit or proceeding described in this Section 6(j) following the expiration of any period permitted for appeal and subject to any stay during appeal shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable laws. EACH OF THE PARTIES TO THIS AGREEMENT MAY BRING A LEGAL DISPUTE ONLY IF HE, SHE OR IT IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY AND FOR ANY COUNTERCLAIM RELATING THERETO. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY NOR ANY PERSON ASSERTING RIGHTS AS A THIRD-PARTY BENEFICIARY SHALL ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. FURTHERMORE, NO PARTY TO THIS AGREEMENT SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED.

(k) Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other terms, conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby are not affected in any manner materially adverse to any party to this Agreement. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties to this Agreement shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

Section 145 of the DGCL provides, generally, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such 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 his or her conduct was unlawful. A corporation may similarly indemnify such person for expenses actually and reasonably incurred by such person in connection with the defense or settlement of any action or suit by or in the right of the corporation, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, in the case of claims, issues and matters as to which such person shall have been adjudged liable to the corporation, provided that a court shall have determined, upon application, that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

In accordance with Section 102(b)(7) of the DGCL, the Existing Charter provides that a director is not personally liable to XPDB or the XPDB Public Stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to XPDB or the XPDB Public Stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision became effective. Accordingly, these provisions have no effect on the availability of equitable remedies such as an injunction or rescission based on a director’s breach of his or her duty of care.

The Existing Charter provides that XPDB indemnify its present and former directors and officers to the maximum extent permitted by the DGCL and that such indemnification is exclusive of any other rights to which those seeking indemnification may be entitled under any bylaw provision, agreement, vote of stockholders or disinterested directors or otherwise.

XPDB has entered into indemnification agreements with each of its current directors and executive officers. These agreements require XPDB to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to XPDB and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

The Proposed Charter will provide for indemnification of the Post-Combination Company’s directors to the maximum extent permitted by the DGCL and Amended and Restated Bylaws provide for indemnification of the Post-Combination Company’s directors and officers to the maximum extent permitted by the DGCL.

In addition, effective upon the consummation of the Business Combination, the Post-Combination Company expects to enter into indemnification agreements with certain directors and officers of the Post-Combination Company. The indemnification agreements will require the Post-Combination Company, among other things, to indemnify its directors against certain liabilities that may arise by reason of their status or service as directors and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Item 22. Undertakings

The undersigned registrant hereby undertakes:

A. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

II-3

Table of Contents

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

B. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

D. That, for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

E. That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

F. That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

G. That every prospectus (i) that is filed pursuant to paragraph (F) immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes

II-4

Table of Contents

of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

H. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

I. To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

J. To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

In order to protect the amounts held in the Trust Account, the Sponsor agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement (a “Target”), reduce the amount of funds in the Trust Account to below (i) $10.10 per Public Share, or $10.20 or $10.30 per public share, as applicable, if the Company extends the period of time it will have to complete an initial Business Combination, or (ii) the lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the Trust assets, in each case net of interest which may be withdrawn to pay taxes, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to seek access to the Trust Account 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 all vendors, service providers (other than 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.	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 $10.10, or $10.20 or $10.30 per Public Share, as applicable, if the Company extends the period of time the Company will have to complete an initial Business Combination.
