LETTER TO STOCKHOLDERS

TO THE STOCKHOLDERS OF THUNDER BRIDGE CAPITAL PARTNERS IV, INC.:

You are cordially invited to attend the special meeting in lieu of an annual meeting of stockholders (the “Meeting”), of Thunder Bridge Capital Partners IV, Inc. (“we,” “us,” “our” or the “Company”), to be held at 2:30 p.m. Eastern Time on June 21, 2023.

The Meeting will be a completely virtual meeting of stockholders, which will be conducted via live webcast. You will be able to attend the Meeting online, vote and submit your questions during the Meeting by visiting https://www.cstproxy.com/thunderbridgecapitalpartnersiv/ext2023.

Even if you are planning on attending the Meeting online, please promptly submit your proxy vote by telephone, or, if you received a printed form of proxy in the mail, by completing, dating, signing and returning the enclosed proxy, so your shares will be represented at the Meeting. Instructions on voting your shares are on the proxy materials you received for the Meeting. Even if you plan to attend the Meeting online, it is strongly recommended you complete and return your proxy card before the Meeting date, to ensure that your shares will be represented at the Meeting if you are unable to attend.

The accompanying proxy statement (the “Proxy Statement”) is dated May 31, 2023, and is first being mailed to stockholders of the Company on or about June 1, 2023. The sole purpose of the Meeting is to consider and vote upon the following proposals (the “Proposals”):

1) a proposal to amend the Company’s amended and restated certificate of incorporation (the “Charter”), in the form set forth in Annex A to the accompanying Proxy Statement (the “Extension Amendment” and such proposal, the “Extension Amendment Proposal”), to extend the date by which the Company must (i) consummate a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”), (ii) cease all operations except for the purpose of winding up, and (iii) as promptly as reasonably possible but no more than ten business days thereafter, redeem the Company’s Class A common stock included as part of the units (the “Public Shares”) sold in the Company’s initial public offering that was consummated on July 2, 2021 (the “IPO”), from July 2, 2023 to July 2, 2024 (or such earlier date as determined by the Company’s board of directors (the “Board”)), which we refer to as the “Extension,” and such later date, the “Extended Date”;

2) a proposal to amend the Charter to provide for the right of a holder of shares of Class B common stock of the Company (“Founder Shares”) to convert such shares into shares of Class A common stock on a one-for-one basis prior to the closing of a Business Combination (the “Founder Share Amendment Proposal” and, together with the Extension Amendment Proposal, the “Charter Amendment Proposals,” and such Charter amendments being herein referred to collectively as the “Charter Amendments”);

3) a proposal to ratify the selection by the audit committee of the Board of Grant Thornton LLP to serve as our independent registered public accounting firm for the year ending December 31, 2023 (the “Auditor Ratification Proposal”); and

4) a proposal to approve the adjournment of the Meeting to a later date or dates, if necessary, 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 other Proposals (the “Adjournment Proposal”). The Adjournment Proposal will only be presented at the Meeting if there are not sufficient votes to approve any of the other Proposals.

Each of the Proposals are more fully described in the accompanying Proxy Statement.

Table of Contents

The purpose of the Extension Amendment Proposal and, if necessary, the Adjournment Proposal, is to allow us additional time to complete the proposed transactions (the “Coincheck Business Combination”) pursuant to that certain Business Combination Agreement (“Business Combination Agreement”), dated as of March 22, 2022 by and among the Company, Coincheck Group B.V., a Dutch private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) (“PubCo”), M1 Co G.K., a Japanese limited liability company (godo kaisha), Coincheck Merger Sub, Inc., a Delaware corporation, and Coincheck, Inc., a Japanese joint stock company (kabushiki kaisha). For more information about the Coincheck Business Combination, see our Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on March 22, 2022.

Our Charter currently provides that the Company has until July 2, 2023 to complete its initial Business Combination. While we are using our best efforts to complete the Coincheck Business Combination as soon as practicable, the Board believes that there will not be sufficient time before July 2, 2023 to complete the Coincheck Business Combination. Accordingly, the Board believes that in order to be able to consummate the Coincheck Business Combination, we will need to obtain the Extension. Without the Extension, the Board believes that there is significant risk that the Company might not, despite our best efforts, be able to complete the Coincheck Business Combination or another initial Business Combination on or before July 2, 2023. If that were to occur, we would be precluded from completing the Coincheck Business Combination or another initial Business Combination and would be forced to liquidate even if our stockholders are otherwise in favor of consummating such transaction.

Therefore, the Board has determined that it is in the best interests of our stockholders to extend the date by which the Company has to consummate the Coincheck Business Combination (or if the Coincheck Business Combination is not consummated, another initial Business Combination) to the Extended Date in order for our stockholders to have the opportunity to participate in our future investment.

If the Extension Amendment is approved and implemented, subject to satisfaction of the conditions to closing in the Business Combination Agreement (including, without limitation, receipt of stockholder approval of the Coincheck Business Combination), the Company intends to complete the Coincheck Business Combination as soon as possible and in any event on or before the Extended Date. However, there is no assurance that we will be able to consummate the Coincheck Business Combination, given the actions that must occur prior to closing of the Coincheck Business Combination.

In connection with the Charter Amendment Proposals, public stockholders may elect (the “Election”) to redeem their Public Shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account (the “Trust Account”), including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares, regardless of whether such public stockholders vote on the Charter Amendment Proposals. If the Charter Amendment Proposals are approved by the requisite vote of stockholders, the remaining holders of Public Shares will retain their right to redeem their Public Shares when the Business Combination is submitted to the stockholders, subject to any limitations set forth in our Charter, as amended by the Charter Amendments. In addition, public stockholders who do not make the Election would be entitled to have their Public Shares redeemed for cash if the Company has not completed the Business Combination by the Extended Date. Our sponsor, TBCP IV, LLC (the “Sponsor”), owns 5,913,196 Founder Shares, which were issued to the Sponsor prior to our IPO, and 648,055 private placement units (the “Private Placement Units”), which were purchased by the Sponsor in a private placement that occurred simultaneously with the completion of the IPO.

To make the Election, you must demand that the Company redeem your Public Shares for a pro rata portion of the funds held in the Trust Account and tender your Public Shares to the Company’s transfer agent at least two business days prior to the Meeting (or June 16, 2023). You may tender your Public Shares by either delivering your share certificate to the transfer agent or by delivering your shares electronically using the Depository Trust Company’s Deposit/Withdrawal At Custodian system. If you hold your Public Shares in street name, you will need to instruct your bank, broker or other nominee to withdraw the Public Shares from your account in order to make the Election.

As of May 26, 2023, based on funds in the Trust Account of approximately $243.5 million as of such date, the pro rata portion of the funds available in the Trust Account for the redemption of Public Shares was approximately $10.29 per Public Share (before taking into account the removal of the accrued interest in the Trust Account to pay our taxes). The closing price of the Company’s Class A common stock on May 26, 2023 as reported on the Nasdaq Capital Market was $10.23. The Company cannot assure stockholders that they will be able to sell their shares of the Company’s Class A 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 such stockholders wish to sell their shares.

Table of Contents

The purpose of the Founder Share Amendment Proposal is to provide the holders of the Founder Shares with the flexibility to assist the Company in meeting the listing requirements of its Class A common stock if necessary or desirable in connection with the Extension and the consummation of the Business Combination. This flexibility may also help the Company in retaining investors. If the Extension Amendment Proposal and the Founder Share Amendment Proposal are approved, the Sponsor has informed the Company that it expects to convert 5,913,195 Founder Shares held by the Sponsor into 5,913,195 shares of Class A common stock (the “Founder Conversion”), and following the Founder Conversion, the Sponsor will continue to own one share of Class B common stock. The shares of Class A common stock that will be issued to the Sponsor in connection with the Founder Conversion will be subject to the same restrictions as shares of Class B common stock before the Founder Conversion, including, among others, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial Business Combination as described in our IPO prospectus filed with the SEC on June 30, 2021 (the “IPO Prospectus”). The shares of Class A common stock that will be issued to the Sponsor in connection with the Founder Conversion will also be entitled to registration rights.

The Adjournment Proposal, if adopted, will allow our Board to adjourn the Meeting to a later date or dates to permit further solicitation of proxies. The Adjournment Proposal will only be presented to our stockholders in the event that there are insufficient votes for, or otherwise in connection with, the approval of the other Proposals.

If the Extension Amendment Proposal is not approved and we do not consummate the Business Combination by July 2, 2023, as contemplated by our IPO Prospectus and in accordance with our Charter, 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 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 the number of then outstanding Public Shares, which redemption will completely extinguish 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 Board, liquidate and dissolve, subject, in the case of clauses (ii) and (iii) above, 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 a Business Combination by July 2, 2023, 24 months from the closing of the IPO. In the event of a liquidation, our Sponsor and our officers and directors will not receive any monies held in the Trust Account as a result of their ownership of the Founder Shares or the Private Placement Units.

Subject to the foregoing, the affirmative vote of at least 65% of the Company’s outstanding shares of common stock, including the Founder Shares, will be required to approve the Extension Amendment Proposal and at least 50% of the Company’s outstanding shares of common stock, including the Founder Shares, will be required to approve the Founder Share Amendment Proposal. Stockholder approval of the Extension Amendment is required for the implementation of our Board’s plan to extend the date by which we must consummate our Business Combination. Notwithstanding stockholder approval of the Charter Amendment Proposals, our Board will retain the right to abandon and not implement the Charter Amendments at any time without any further action by our stockholders.

Approval of the Auditor Ratification Proposal requires the affirmative vote of the majority of the votes cast by stockholders represented in person (including virtually) or by proxy at the Meeting.

Our Board has fixed the close of business on May 10, 2023 as the date for determining the Company stockholders entitled to receive notice of and vote at the Meeting and any adjournment thereof. Only holders of record of the Company’s common stock on that date are entitled to have their votes counted at the Meeting or any adjournment thereof.

Table of Contents

You are not being asked to vote on the Business Combination at this time. If the Extension Amendment is implemented and you do not elect to redeem your Public Shares, provided that you are a stockholder on the record date for a meeting to consider the Business Combination, you will retain the right to vote on the Business Combination when it is submitted to stockholders and the right to redeem your Public Shares for cash in the event the Business Combination is approved and completed or we have not consummated a Business Combination by the Extended Date.

After careful consideration of all relevant factors, the Board has determined that the Extension Amendment Proposal, THE FOUNDER SHARE AMENDMENT PROPOSAL, the AUDITOR RATIFICATION PROPOSAL AND, if presented, the Adjournment Proposal are advisable and recommends that you vote or give instruction to vote “FOR” such proposals.

Under Delaware law and the Company’s bylaws, no other business may be transacted at the Meeting.

Enclosed is the Proxy Statement containing detailed information concerning the Extension Amendment Proposal, the Founder Share Amendment Proposal, the Auditor Ratification Proposal, the Adjournment Proposal and the Meeting. Whether or not you plan to attend the Meeting, we urge you to read this material carefully and vote your shares. Stockholders will have the opportunity to present questions to the management of the Company at the Meeting, which is being held, in part, to satisfy the annual meeting requirement of the Nasdaq Stock Market LLC.

Your vote is important. If you are a stockholder of record, please sign, date and return your proxy card as soon as possible to make sure that your shares are represented at the Meeting. If you are a stockholder of record, you may also cast your vote online at the Meeting. If your shares are held in an account at a brokerage firm or bank, you must instruct your broker or bank how to vote your shares, or you may cast your vote online at the Meeting by obtaining a proxy from your brokerage firm or bank. Your failure to vote or instruct your broker or bank how to vote will have the same effect as voting “AGAINST” the Extension Amendment Proposal and the Founder Share Amendment Proposal, and an abstention will have the same effect as voting “AGAINST” the Extension Amendment Proposal and the Founder Share Amendment Proposal. Abstentions and broker-non votes will be considered present for purposes of establishing a quorum for the Auditor Ratification Proposal; broker non-votes will count as votes cast on the Auditor Ratification Proposal, whereas abstentions will not count as votes cast and will have no effect on the outcome of the vote on the Auditor Ratification Proposal. Abstentions, while considered present for the purposes of establishing a quorum, will not count as votes cast and will have no effect on the outcome of the vote on the Adjournment Proposal. Broker non-votes will also not count as votes cast and will have no effect on the outcome of the vote on the Adjournment Proposal. Failure to vote by proxy or to vote in person (including virtually) at the Meeting will have no effect on the outcome of the vote on the Adjournment Proposal.

NOTICE OF SPECIAL MEETING IN LIEU OF ANNUAL MEETING OF STOCKHOLDERS

PROXY STATEMENT

The special meeting in lieu of an annual meeting of stockholders (the “Meeting”), of Thunder Bridge Capital Partners IV, Inc. (“we,” “us,” “our” or the “Company”), is to be held at 2:30 p.m. Eastern Time on June 21, 2023. Stockholders will have the opportunity to present questions to the management of the Company (the “Management”) at the Meeting, which is being held, in part, to satisfy the annual meeting requirement of the Nasdaq Stock Market LLC (“Nasdaq”).

You will be able to attend, vote your shares, and submit questions during the Meeting via a live webcast available at https://www.cstproxy.com/thunderbridgecapitalpartnersiv/ext2023. The Meeting will be held for the sole purpose of considering and voting upon the following proposals (the “Proposals”):

1) a proposal to amend the Company’s amended and restated certificate of incorporation (the “Charter”), in the form set forth in Annex A hereto (the “Extension Amendment” and such proposal, the “Extension Amendment Proposal”), to extend the date by which the Company must (i) consummate a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”), (ii) cease all operations except for the purpose of winding up, and (iii) redeem or repurchase 100% of the Company’s Class A common stock included as part of the units (the “Public Shares”) sold in the Company’s initial public offering that was consummated on July 2, 2021 (the “IPO”), from July 2, 2023 to July 2, 2024 (or such earlier date as determined by the Company’s board of directors (the “Board”)), which we refer to as the “Extension,” and such later date, the “Extended Date”;

3) a proposal to ratify the selection by the audit committee (the “Audit Committee”) of the Board of Grant Thornton LLP (“Grant Thornton”) to serve as our independent registered public accounting firm for the year ending December 31, 2023 (the “Auditor Ratification Proposal”); and

The purpose of the Extension Amendment Proposal and, if necessary, the Adjournment Proposal, is to allow us additional time to complete the proposed transactions (the “Coincheck Business Combination”) pursuant to that certain Business Combination Agreement (“Business Combination Agreement”), dated as of March 22, 2022 by and among the Company, Coincheck Group B.V., a Dutch private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) (“PubCo”), M1 Co G.K., a Japanese limited liability company (godo kaisha) (“HoldCo”), Coincheck Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and Coincheck, Inc., a Japanese joint stock company (kabushiki kaisha) (“Coincheck”). For more information about the Coincheck Business Combination, see our Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 22, 2022 (the “Business Combination 8-K”).

Business Combination. Accordingly, the Board believes that in order to be able to consummate the Coincheck Business Combination, we will need to obtain the Extension. Without the Extension, the Board believes that there is significant risk that the Company might not, despite our best efforts, be able to complete the Coincheck Business Combination or another initial Business Combination on or before July 2, 2023. If that were to occur, we would be precluded from completing the Coincheck Business Combination or another initial Business Combination and would be forced to liquidate even if our stockholders are otherwise in favor of consummating such transaction.

In connection with the Charter Amendment Proposals, public stockholders may elect (the “Election”) to redeem their Public Shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Company’s trust account (the “Trust Account”), including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares, regardless of whether such public stockholders vote on the Charter Amendment Proposals. If the Charter Amendment Proposals are approved by the requisite vote of stockholders, the remaining holders of Public Shares will retain their right to redeem their Public Shares when the Business Combination is submitted to the stockholders, subject to any limitations set forth in our Charter, as amended by the Charter Amendments. In addition, public stockholders who do not make the Election would be entitled to have their Public Shares redeemed for cash if the Company has not completed a Business Combination by the Extended Date. Our sponsor, TBCP IV, LLC (the “Sponsor”), owns 5,913,196 Founder Shares, which were issued to the Sponsor prior to our IPO, and 648,055 private placement units (the “Private Placement Units”), which were purchased by the Sponsor in a private placement that occurred simultaneously with the completion of the IPO.

To make the Election, you must demand that the Company redeem your Public Shares for a pro rata portion of the funds held in the Trust Account and tender your shares to the Company’s transfer agent at least two business days prior to the Meeting (or June 16, 2023). You may tender your shares by either delivering your share certificate to the transfer agent or by delivering your shares electronically using the Depository Trust Company’s (“DTC”) Deposit/Withdrawal At Custodian (“DWAC”) system. If you hold your Public Shares in street name, you will need to instruct your bank, broker or other nominee to withdraw the Public Shares from your account in order to make the Election.

The withdrawal of funds from the Trust Account in connection with the Election will reduce the amount held in the Trust Account following the Election and the amount remaining in the Trust Account may be significantly less than the approximately $243.5 million that was in the Trust Account as of May 26, 2023. In such event, the Company may need to obtain additional funds to complete the Business Combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

Notwithstanding stockholder approval of the Charter Amendment Proposals, our Board will retain the right to abandon and not implement the Charter Amendments at any time without any further action by our stockholders.

others, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial Business Combination as described in the our IPO prospectus filed with the SEC on June 30, 2021 (the “IPO Prospectus”). The shares of Class A common stock that will be issued to the Sponsor in connection with the Founder Conversion will also be entitled to registration rights.

If the Extension Amendment Proposal is not approved and we do not consummate the Business Combination by July 2, 2023, as contemplated in our IPO Prospectus and in accordance with our Charter, 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 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 the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and the Board, liquidate and dissolve, subject, in the case of clauses (ii) and (iii) above, 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 a Business Combination by July 2, 2023, 24 months from the closing of the IPO (the “Combination Period”). In the event of a liquidation, our Sponsor and our officers and directors will not receive any monies held in the Trust Account as a result of their ownership of the Founder Shares or the Private Placement Units. As a consequence, a liquidating distribution will be made only with respect to the Public Shares.

If the Company liquidates, the Sponsor has agreed to indemnify us to the extent any claims by a third party for services rendered or products sold to us, or any claims by a prospective target business with which we have discussed entering into an acquisition agreement, reduce the amount of funds in the Trust Account to below (i) $10.00 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, except as to any (x) claims by a third party who executed a waiver of any and all rights to seek access to our Trust Account and (y) claims under our indemnity of the underwriters of our IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, 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. We cannot assure you, however, that the Sponsor would be able to satisfy those obligations. As of May 26, 2023, based on funds in the Trust Account of approximately $243.5 million as of such date, the pro rata portion of the funds available in the Trust Account for the redemption of Public Shares was approximately $10.29 per Public Share (before taking into account the removal of the accrued interest in the Trust Account to pay our taxes). Nevertheless, the Company cannot assure you that the per-share distribution from the Trust Account, if the Company liquidates, will not be less than $10.29, plus interest, due to unforeseen claims of creditors.

Under the General Corporation Law of the State of Delaware (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. If the 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 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.

Table of Contents

Because the Company will not be complying with Section 280 of the DGCL, as described in our IPO Prospectus, 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 10 years following our dissolution. However, because we are a blank check company, rather than an operating company, and our operations have been limited to searching for prospective target businesses to acquire, the only likely claims to arise would be from our vendors (such as lawyers or investment bankers) or prospective target businesses.

If the Extension Amendment Proposal is approved, the Company, pursuant to the terms of the investment management trust agreement, dated June 29, 2021 (the “Trust Agreement”), by and between the Company and Continental Stock Transfer & Trust Company (“Continental”), will (i) remove from the Trust Account an amount (the “Withdrawal Amount”), equal to the number of Public Shares properly redeemed multiplied by the per-share price, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares, and (ii) deliver to the holders of such redeemed Public Shares their portion of the Withdrawal Amount. The remainder of such funds shall remain in the Trust Account and be available for use by the Company to complete a Business Combination on or before the Extended Date. Holders of Public Shares who do not redeem their Public Shares now will retain their redemption rights and their ability to vote on a Business Combination through the Extended Date, if the Extension Amendment Proposal is approved.

Our Board has fixed the close of business on May 10, 2023 (the “Record Date”) as the date for determining the Company stockholders entitled to receive notice of and vote at the Meeting and any adjournment thereof. Only holders of record of the Company’s common stock on that date are entitled to have their votes counted at the Meeting or any adjournment thereof. On the Record Date of the Meeting, there were 24,300,839 shares of our Class A common stock and 5,913,196 shares of Class B common stock outstanding. The Company’s warrants do not have voting rights in connection with the Proposals.

This proxy statement (the “Proxy Statement”) contains important information about the Meeting and the Proposals. Please read it carefully and vote your shares.

We will pay for the entire cost of soliciting proxies from our working capital. We have engaged Morrow Sodali LLC (the “Solicitation Agent”) to assist in the solicitation of proxies for the Meeting. We have agreed to pay the Solicitation Agent approximately $30,000 in connection with such services for the Meeting. We will also reimburse the Solicitation Agent for reasonable out-of-pocket expenses and will indemnify the Solicitation Agent and its affiliates against certain claims, liabilities, losses, damages and expenses. In addition to these mailed proxy materials, our Board and the Management may also solicit proxies in person, by telephone or by other means of communication. These parties will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners. While the payment of these expenses will reduce the cash available to us to consummate the Business Combination if the Extension Amendment is approved, we do not expect such payments to have a material effect on our ability to consummate an initial Business Combination.

This Proxy Statement is dated May 31, 2023 and is first being mailed to stockholders on or about June 1, 2023.

QUESTIONS AND ANSWERS ABOUT THE MEETING

These Questions and Answers are only summaries of the matters they discuss. They do not contain all of the information that may be important to you. You should read carefully the entire document, including the annexes to this Proxy Statement.

Why am I receiving this Proxy Statement?

This Proxy Statement and the enclosed proxy card are being sent to you in connection with the solicitation of proxies by the Board for use at the Meeting, which is a special meeting in lieu of an annual meeting of stockholders, to be held at 2:30 p.m. Eastern Time on June 21, 2023, or at any adjournments or postponements thereof. This Proxy Statement summarizes the information that you need to make an informed decision on the proposals to be considered at the Meeting. This Proxy Statement and the enclosed proxy card were first sent to our stockholders on or about June 1, 2023.

We are a blank check company formed in Delaware on January 7, 2021, for the purpose of effecting a Business Combination with one or more businesses. On July 2, 2021, we consummated our IPO, as well as a private placement, from which we derived gross proceeds of $231,250,000 in the aggregate. On August 9, 2021, the underwriters exercised their over-allotment option in part and we sold additional Private Placement Units to the Sponsor, from which we derived additional aggregate gross proceeds of $11,758,390. Following the closing of the IPO and the over-allotment purchase, an aggregate amount of $ 236,527,840 ($10.00 per unit) from the net proceeds of the sale of the units in the IPO (including the over-allotment units) and the sale of the Private Placement Units was placed in the Trust Account.

Like most blank check companies, our Charter provides for the return of our IPO proceeds held in the Trust Account to the holders of our Public Shares if there is no qualifying Business Combination consummated on or before a certain date (in our case, July 2, 2023). Our Board believes that it is in the best interests of the stockholders to continue our existence until the Extended Date in order to allow us more time to complete the Business Combination.

The Meeting is being held, in part, to allow us additional time to complete the Business Combination.

Why does the Company need to hold an annual meeting?

The Meeting is also being held, in part, to satisfy the annual meeting requirement of Nasdaq. Nasdaq Listing Rule 5620(a) requires that we hold an annual meeting of stockholders within 12 months after our fiscal year ended December 31, 2022. At the Meeting, you will have the opportunity to present questions to the Management.

The Proposals

What is being voted on?

You are being asked to vote on four Proposals:

• Extension Amendment Proposal. A proposal to amend our Charter to extend the date by which we have to either consummate a Business Combination or wind up the Company and redeem 100% of the Public Shares sold in the IPO from July 2, 2023 to July 2, 2024 (or such earlier date as determined by the Board);

• Founder Share Amendment Proposal. A proposal to amend our Charter to provide for the right of a holder of Founder Shares to convert such shares into shares of Class A common stock on a one-for-one basis prior to the closing of a Business Combination;

• Auditor Ratification Proposal. A proposal to ratify the selection by the Audit Committee of Grant Thornton LLP to serve as our independent registered public accounting firm for the year ending December 31, 2023; and

• Adjournment Proposal. A proposal to approve the adjournment of the Meeting to a later date or dates, if necessary, 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 other Proposals.

Table of Contents

Why is the Company proposing the Extension Amendment Proposal?

Our Charter provides for the return of our IPO proceeds held in the Trust Account to the holders of Public Shares if there is no qualifying Business Combination consummated on or before July 2, 2023. As explained below, we will not be able to complete a Business Combination by that date and therefore, we are asking for an extension of this timeframe.

The purpose of the Extension Amendment Proposal and, if necessary, the Adjournment Proposal, is to allow us additional time to complete the Coincheck Business Combination, if needed. The Extension Amendment Proposal is required for the implementation of our Board’s plan to extend the date that we have to complete an initial Business Combination, specifically the Coincheck Business Combination. Approval of the Extension Amendment Proposal is a condition to the implementation of the Extension.

While we are using our best efforts to complete the Coincheck Business Combination as soon as practicable, the Board believes that there will not be sufficient time before July 2, 2023 to complete the Coincheck Business Combination. Accordingly, the Board believes that in order to be able to consummate the Coincheck Business Combination, we will need to obtain the Extension. Without the Extension, the Board believes that there is significant risk that the Company might not, despite our best efforts, be able to complete the Coincheck Business Combination or another initial Business Combination on or before July 2, 2023. If that were to occur, we would be precluded from completing the Coincheck Business Combination or another initial Business Combination and would be forced to liquidate even if our stockholders are otherwise in favor of consummating such transaction.

The Board believes that given the Company’s expenditure of time, effort and money on the Coincheck Business Combination, circumstances warrant ensuring that the Company is in the best position possible to consummate the Coincheck Business Combination and that it is in the best interests of the Company’s stockholders that the Company obtain the Extension if needed. The Company believes that the Coincheck Business Combination will provide significant benefits to its stockholders. For more information about the Coincheck Business Combination, see the Business Combination 8-K. Accordingly, the Board is proposing the Extension Amendment Proposal to amend our Charter in the form set forth in Annex A hereto to extend the date by which we must (i) consummate a Business Combination, (ii) cease our operations if we fail to complete such Business Combination, and (iii) redeem or repurchase 100% of the Public Shares sold in our IPO from July 2, 2023 to July 2, 2024 (or such earlier date as determined by the Board).

Why is the Company proposing the Adjournment Proposal?

The Company is proposing the Adjournment Proposal to provide flexibility to adjourn the Meeting to give the Company more time to seek approval of the Extension Amendment Proposal, the Founder Share Amendment Proposal and the Auditor Ratification Proposal, if necessary. If the Adjournment Proposal is not approved, the Company will not have the ability to adjourn the Meeting to a later date for the purpose of soliciting additional proxies. In such event,

Table of Contents

the Extension would not be completed, the Company would 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 Board, dissolving and liquidating.

Why should I vote “FOR” the Extension Amendment Proposal?

Our Board believes stockholders should have an opportunity to evaluate the Business Combination. Accordingly, the Board is proposing the Extension Amendment Proposal to amend our Charter in the form set forth in Annex A hereto to extend the date by which we must (i) consummate a Business Combination, (ii) cease our operations if we fail to complete such Business Combination, and (iii) redeem or repurchase 100% of the Public Shares sold in our IPO from July 2, 2023 to July 2, 2024 (or such earlier date as determined by the Board). The Extension would give the Company the opportunity to complete the Business Combination.

Our Charter provides that if our stockholders approve an amendment to our Charter that would affect the substance or timing of our obligation to redeem 100% of our Public Shares if we do not complete our Business Combination before July 2, 2023, we will provide our public stockholders with the opportunity to redeem all or a portion of their Public Shares upon such approval at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares. We believe that this Charter provision was included to protect our stockholders from having to sustain their investments for an unreasonably long period if we failed to find a suitable Business Combination in the timeframe contemplated by the Charter.

Our Board recommends that you vote in favor of the Extension Amendment Proposal.

Why should I vote “FOR” the Founder Share Amendment Proposal?

The purpose of the Founder Share Amendment Proposal is to provide the holders of the Founder Shares with the flexibility to assist the Company in meeting the listing requirements of its Class A common stock if necessary or desirable in connection with the Extension and the consummation of the Business Combination. This flexibility may also help the Company in retaining investors. If the Extension Amendment Proposal and the Founder Share Amendment Proposal are approved, the Sponsor has informed the Company that it expects to convert 5,913,195 Founder Shares held by the Sponsor into 5,913,195 shares of Class A common stock, and following the Founder Conversion, the Sponsor will continue to own one share of Class B common stock. The shares of Class A common stock that will be issued to the Sponsor in connection with the Founder Conversion will be subject to the same restrictions as shares of Class B common stock before the Founder Conversion, including, among others, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial Business Combination as described in our IPO Prospectus. The shares of Class A common stock that will be issued to the Sponsor in connection with the Founder Conversion will also be entitled to registration rights.

If the Founder Share Amendment Proposal is not approved, we believe it may reduce our flexibility to maintain a listing of our Class A common stock.

Our Board recommends that you vote in favor of the Founder Share Amendment Proposal.

Why should I vote “FOR” the Auditor Ratification Proposal?

Grant Thornton LLP has served as the Company’s independent registered public accounting firm since January 7, 2021. Our Audit Committee and Board believe that stability and continuity in the Company’s auditor is important as we continue to search for and complete the Business Combination.

Our Board recommends that you vote in favor of the Auditor Ratification Proposal.

Why should I vote “FOR” the Adjournment Proposal?

If the Adjournment Proposal is not approved by our stockholders, our Board may not be able to adjourn the Meeting to a later date in the event that there are insufficient votes for, or otherwise in connection with, the approval of the other Proposals.

Table of Contents

What vote is required to adopt the Proposals?

• Extension Amendment Proposal. The approval of the Extension Amendment Proposal will require the affirmative vote of holders of at least 65% of our outstanding shares of common stock, including the Founder Shares, on the Record Date.

• Founder Share Amendment Proposal. The approval of the Founder Share Amendment Proposal will require the affirmative vote of holders of at least 50% of our outstanding shares of common stock, including the Founder Shares, on the Record Date.

• Auditor Ratification Proposal. Approval of the proposal to ratify the selection of Grant Thornton as the Company’s independent registered public accounting firm requires the affirmative vote of the majority of the votes cast by holders of the Company’s common stock present (including virtually) or represented by proxy and entitled to vote thereon.

What if I don’t want to vote “FOR” any of the Proposals?

If you do not want either of the Charter Amendment Proposals to be approved, you may abstain, not vote, or vote “AGAINST” such proposal. You will be entitled to redeem your Public Shares for cash in connection with this vote whether or not you vote on either of the Charter Amendment Proposals, so long as you make the Election. If the Charter Amendment Proposals are approved, and the Charter Amendments are implemented, then the Withdrawal Amount will be withdrawn from the Trust Account and paid to the redeeming holders.

If you do not want the Auditor Ratification Proposal to be approved, you must vote against such proposal. Abstentions will have no effect on the Auditor Ratification Proposal.

If you do not want the Adjournment Proposal to be approved, you must vote against such proposal. Abstentions and broker non-votes (as described below) will have no effect on such proposal.

How do the Company insiders intend to vote their shares?

All of our directors, executive officers and their respective affiliates are expected to vote any common stock over which they have voting control (including any Public Shares owned by them) in favor of the Extension Amendment Proposal, the Founder Share Amendment Proposal, the Auditor Ratification Proposal and the Adjournment Proposal. Currently, our Sponsor, Board and Management own approximately 22% of our issued and outstanding shares of common stock, including 5,913,196 Founder Shares and 648,055 shares of Class A common stock underlying the Private Placement Units held by our Sponsor, and 100,000 Public Shares purchased in the IPO and held by our Chief Executive Officer.

In addition, the Sponsor may enter into arrangements with a limited number of stockholders pursuant to which such stockholders would agree not to redeem the Public Shares beneficially owned by them in connection with the Extension Amendment Proposal. The Sponsor may provide such stockholders either Company securities or membership interests in the Sponsor pursuant to such arrangements.

Does the Board recommend voting for the approval of the Proposals?

Yes. After careful consideration of the terms and conditions of these Proposals, our Board has determined that the Extension Amendment Proposal, the Founder Share Amendment Proposal, the Auditor Ratification Proposal and, if presented, the Adjournment Proposal are in the best interests of the Company and its stockholders. The Board recommends that our stockholders vote “FOR” the Extension Amendment Proposal, “FOR” the Founder Share Amendment Proposal, “FOR” the Auditor Ratification Proposal and “FOR” the Adjournment Proposal, if presented.

Table of Contents

What interests do the Company’s Sponsor, directors and officers have in the approval of the Proposals?

The Sponsor, directors and officers have interests in the Proposals that may be different from, or in addition to, your interests as a stockholder. These interests include ownership of (i) 5,913,196 Founder Shares (purchased for a nominal price) and 648,055 Private Placement Units (purchased for $6,480,550) by the Sponsor, which securities would expire worthless if the Coincheck Business Combination or another Business Combination is not consummated, and (ii) a promissory note in the principal amount of up to $1,500,000 issued in connection with working capital loans made by the Sponsor, of which $226,000 was outstanding as of March 31, 2023. See the section below entitled “Proposal One — The Extension Amendment Proposal — Interests of the Sponsor and our Directors and Officers.”

Do I have appraisal rights if I object to any of the Proposals?

Our stockholders do not have appraisal rights in connection with the Proposals under the DGCL.

The Charter Amendment Proposals

When would the Board abandon the Charter Amendment Proposals?

Our Board will abandon the Extension Amendment if our stockholders do not approve the Extension Amendment Proposal.

The Founder Share Amendment is conditioned on the approval of the Extension Amendment Proposal.

In addition, notwithstanding stockholder approval of the Charter Amendment Proposals, our Board will retain the right to abandon and not implement the Charter Amendments at any time without any further action by our stockholders.

What happens if the Extension Amendment Proposal is not approved?

Our Board will abandon the Charter Amendments if our stockholders do not approve the Extension Amendment Proposal.

If the Extension Amendment Proposal is not approved and we do not consummate the Business Combination by July 2, 2023, as contemplated by our IPO Prospectus and in accordance with our Charter, 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 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 the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and the Board, liquidate and dissolve, subject, in the case of clauses (ii) and (iii) above, 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 our Business Combination within the Combination Period. There will be no distribution from the Trust Account with respect to our warrants, which will expire worthless in the event of our winding up.

In the event of a liquidation, our Sponsor and our officers and directors will not receive any monies held in the Trust Account as a result of their ownership of the Founder Shares or the Private Placement Units.

If the Charter Amendment Proposals are approved, what happens next?

If the Extension Amendment Proposal is approved and implemented, the Company will continue to attempt to consummate the Coincheck Business Combination (or, if the Coincheck Business Combination is not consummated, another initial Business Combination) until the Extended Date.

If the Founder Share Amendment Proposal is approved, the Sponsor plans to convert on a one-for-one basis 5,913,195 Founder Shares held by the Sponsor into 5,913,195 shares of Class A common stock, and following the Founder Conversion, the Sponsor will continue to own one share of Class B common stock. The shares of Class A

Table of Contents

common stock that will be issued to the Sponsor in connection with the Founder Conversion will be subject to the same restrictions as shares of Class B common stock before the Founder Conversion, including, among others, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial Business Combination as described in our IPO Prospectus. The shares of Class A common stock that will be issued to the Sponsor in connection with the Founder Conversion will also be entitled to registration rights.

Upon approval of the Charter Amendment Proposals, we will file an amendment to the Charter with the Secretary of State of the State of Delaware in the form set forth in Annex A hereto. We will remain a reporting company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and expect that our units, Public Shares and warrants included as part of the units sold in the IPO (the “Public Warrants”) will remain publicly traded.

If the Charter Amendment Proposals are approved, the removal of the Withdrawal Amount from the Trust Account will reduce the amount remaining in the Trust Account and increase the percentage interest of our common stock held by the Sponsor and our directors and our officers as a result of their ownership of the Founder Shares.

Notwithstanding stockholder approval of the Extension Amendment Proposal, our Board will retain the right to abandon and not implement the Extension Amendment at any time without any further action by our stockholders.

What happens to our warrants if the Extension Amendment Proposal is not approved?

If the Extension Amendment Proposal is not approved and we do not consummate the Business Combination by July 2, 2023, there will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our Business Combination within the Combination Period. There will be no distribution from the Trust Account with respect to our warrants, which will expire worthless in the event of our winding up.

What happens to our warrants if the Extension Amendment Proposal is approved?

If the Extension Amendment Proposal is approved, we will retain the blank check company restrictions previously applicable to us and continue to attempt to consummate a Business Combination until the Extended Date. The Public Warrants will remain outstanding and only become exercisable 30 days after the completion of a Business Combination, provided that we have an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the warrants and a current prospectus relating to them is available (or we permit holders to exercise warrants on a cashless basis).

What happens if the Founder Share Amendment Proposal is not approved?

Our Board will abandon the Founder Share Amendment if our stockholders do not approve the Founder Share Amendment Proposal. If the Founder Share Amendment Proposal is not approved, we believe it may reduce our flexibility to maintain a listing of our Class A common stock.

Would I still be able to exercise my redemption rights if I vote “AGAINST” the Extension Amendment Proposal or the Founder Share Amendment Proposal?

Yes, assuming you are a stockholder as of the Record Date and continue to hold your shares at the time of your Election (and subsequent redemption payment). However, redemption payments for Elections in connection with this Meeting will only be made if the Charter Amendment Proposals receive the requisite stockholder approvals. If you do not redeem your Public Shares in connection with the Meeting, you will retain your right to redeem your Public Shares upon consummation of the Business Combination, subject to any limitations set forth in the Charter.

How do I redeem my shares of Class A common stock?

If the Extension Amendment is implemented, each of our public stockholders that made an Election may seek to redeem all or a portion of their Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number

Table of Contents

of then outstanding Public Shares. If you choose not to make an Election in connection with the Charter Amendment Proposals, you will also be able to redeem your Public Shares in connection with any stockholder vote to approve a proposed Business Combination, including the Coincheck Business Combination, or if we have not consummated a Business Combination by the Extended Date.

In order to exercise your redemption rights, you must, prior to 5:00 p.m. Eastern Time on June 16, 2023 (two business days before the Meeting) tender your shares physically or electronically and submit a request in writing that we redeem your Public Shares for cash to Continental, our transfer agent, at the following address:

Continental Stock Transfer & Trust Company
1 State Street Plaza, 30th Floor
New York, New York 10004
Attn: SPAC Redemption Team
E-mail: spacredemptions@continentalstock.com

Information about the Meeting

How do I attend the Meeting?

As a registered stockholder, you received a proxy card from Continental. The form contains instructions on how to attend the Meeting including the URL address, https://www.cstproxy.com/thunderbridgecapitalpartnersiv/ext2023, along with your 12-digit control number. You will need your control number for access. If you do not have your control number, contact Continental at the phone number or e-mail address below. Beneficial investors who hold shares through a bank, broker or other intermediary, will need to contact them and obtain a legal proxy. Once you have your legal proxy, contact Continental to have a control number generated. Continental Stock Transfer & Trust Company contact information is as follows: 917-262-2373, or proxy@continentalstock.com.

If you do not have internet capabilities, you can listen to the meeting by dialing: 1 800-450-7155 (toll-free) within the U.S. and Canada, or +1 857-999-9155 (standard rates apply) outside of the U.S. and Canada. When prompted, enter the pin number 4506805#. This is a listen-only option, and you will not be able to vote or enter questions during the meeting.

How do I change or revoke my vote after I have voted?

You may change your vote by e-mailing a later-dated, signed proxy card to our Chief Financial Officer at whoulihan@thunderbridge.us, so that it is received by our Chief Financial Officer prior to the Meeting, or by attending the Meeting online and voting. You also may revoke your proxy by sending a notice of revocation to our Chief Financial Officer, which must be received by our Chief Financial Officer prior to the Meeting.

Please note, however, that if on the Record Date, your shares were held not in your name, but rather in an account at a brokerage firm, custodian bank, or other nominee, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. If your shares are held in street name, and you wish to attend the Meeting and vote at the Meeting online, you must follow the instructions included with the enclosed proxy card.

How are votes counted?

• Extension Amendment Proposal. The Extension Amendment Proposal must be approved by the affirmative vote of at least 65% of the outstanding shares of our common stock as of the Record Date, including the Founder Shares, voting together as a single class. Accordingly, a Company stockholder’s failure to vote by proxy or to vote online at the Meeting or an abstention with respect to the Extension Amendment Proposal will have the same effect as a vote “AGAINST” such proposal.

• Founder Share Amendment Proposal. The Founder Share Amendment Proposal must be approved by the affirmative vote of 50% of the outstanding shares of our common stock, including the Founder Shares, as of the Record Date. Accordingly, a Company stockholder’s failure to vote by proxy or to vote online at the Meeting or an abstention with respect to the Founder Share Amendment Proposal will have the same effect as a vote “AGAINST” such proposal.

Table of Contents

• Auditor Ratification Proposal. The ratification of the appointment of Grant Thornton requires the vote of a majority of the votes cast by our represented in person (including virtually) or by proxy at the Meeting. Abstentions will have no effect on this proposal. However, your shares may be voted as broker non-votes by your brokerage firm for the Auditor Ratification Proposal. See the subsection below entitled “Will my shares be voted if I do not provide my proxy?” for more information about broker-non votes.

• Adjournment Proposal. Approval of the Adjournment Proposal, if presented, requires the affirmative vote of the majority of the votes cast by stockholders present in person (including virtually) or represented by proxy at the Meeting and entitled to vote thereon. Accordingly, a stockholder’s failure to vote by proxy or to vote online at the Meeting will have no effect on the outcome of any vote on the Adjournment Proposal. Abstentions will also have no effect on this proposal.

If my shares are held in “street name,” will my broker automatically vote them for me?

No. Under the rules of various national and regional securities exchanges, your broker, bank, or nominee cannot vote your shares with respect to non-discretionary matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank, or nominee.

We believe the Extension Amendment Proposal, the Founder Share Amendment Proposal and the Adjournment Proposal, if presented, will be considered non-discretionary, and therefore your broker, bank, or nominee cannot vote your shares without your instruction on these proposals. Consequently, your bank, broker, or other nominee can vote your shares for these proposals only if you provide instructions on how to vote. You should instruct your broker to vote your shares in accordance with directions you provide. If your shares are held by your broker as your nominee, which we refer to as being held in “street name,” you may need to obtain a proxy form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker to vote your shares.

In contrast, brokerage firms generally have the authority to vote shares not voted by customers on certain “routine” matters, including the ratification of an independent registered public accounting firm. Accordingly, at the Meeting, your shares may be voted by your brokerage firm for the Auditor Ratification Proposal.

How many votes must be present to hold the Meeting?

A quorum of stockholders is necessary to hold a valid meeting. Holders of a majority in voting power of our common stock on the Record Date issued and outstanding and entitled to vote at the Meeting, present in person (including virtually) or represented by proxy, constitute a “quorum.”

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote online at the Meeting. Abstentions will be counted towards the quorum requirement. In the absence of a quorum, the chairman of the Meeting has the power to adjourn the Meeting. As of the Record Date for the Meeting, 15,107,018 shares of our common stock would be required to achieve a quorum.

Who can vote at the Meeting?

Only holders of record of our common stock at the close of business on the Record Date, May 10, 2023, are entitled to have their vote counted at the Meeting and any adjournments or postponements thereof. On the Record Date, 24,300,839 shares of our Class A common stock and 5,913,196 shares of Class B common stock were outstanding and entitled to vote.

What is the difference between a stockholder of record and a beneficial owner of shares held in street name?

• Stockholder of Record: Shares Registered in Your Name. If on the Record Date your shares were registered directly in your name with our transfer agent, Continental, then you are a “stockholder of record.”

• Beneficial Owner: Shares Registered in the Name of a Broker or Bank. If on the Record Date your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the “beneficial owner” of shares held in “street name” and these proxy materials are being forwarded to you by that organization.

Table of Contents

What is the proxy card?

The proxy card enables you to appoint each of Gary A. Simanson, our Chief Executive Officer, President and Director, and William A. Houlihan, our Chief Financial Officer, as your representatives at the Meeting. By completing and returning the proxy card, you are authorizing Mr. Simanson or Mr. Houlihan to vote your shares at the Meeting in accordance with your instructions on the proxy card. This way, your shares will be voted whether or not you attend the Meeting. Even if you plan to attend the Meeting, it is strongly recommended that you complete and return your proxy card before the Meeting date in case your plans change. If a proposal comes up for vote at the Meeting that is not on the proxy card, the proxies will vote your shares, under your proxy, according to their best judgment.

Will my shares be voted if I do not provide my proxy?

If you hold your shares directly in your own name, they will not be voted if you do not provide a proxy.

Your shares may be voted under certain circumstances if they are held in the name of a brokerage firm. Brokerage firms generally have the authority to vote shares not voted by customers on certain “routine” matters, including the ratification of an independent registered public accounting firm. Accordingly, at the Meeting, your shares may be voted by your brokerage firm for the Auditor Ratification Proposal.

Brokers are prohibited from exercising discretionary authority on non-routine matters. The Extension Amendment Proposal, Founder Share Amendment Proposal and Adjournment Proposal are considered non-routine matters, and therefore brokers cannot exercise discretionary authority regarding these proposals for beneficial owners who have not returned proxies to the brokers (so-called “broker non-votes”).

How can I vote if I am a stockholder of record?

• Online. If you are a stockholder of record, you may vote online at the Meeting.

• By Mail. You may vote by proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope.

Whether or not you plan to attend the Meeting online, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Meeting and vote online if you have already voted by proxy.

How can I vote if I am a beneficial owner of shares held in street name?

• Online at the Meeting. If you are a beneficial owner of shares held in street name and you wish to vote online at the Meeting, you must obtain a legal proxy from the brokerage firm, bank, broker-dealer or other similar organization that holds your shares. Please contact that organization for instructions regarding obtaining a legal proxy.

• By mail. You may vote by proxy by filling out the vote instruction form and sending it back in the envelope provided by your brokerage firm, bank, broker-dealer or other similar organization that holds your shares.

• By telephone or over the Internet. You may vote by proxy by submitting your proxy by telephone or over the Internet (if those options are available to you) in accordance with the instructions on the enclosed proxy card or voting instruction card. This is allowed if you hold shares in street name and your bank, broker or other nominee offers those alternatives. Although most banks, brokers and other nominees offer these voting alternatives, availability and specific procedures vary.

You are also invited to attend the Meeting. For more information, see the subsection above entitled “How do I attend the Meeting.”

What happens if I do not indicate how to vote my proxy?

If you sign your proxy card without providing further instructions, your shares of the Company’s common stock will be voted “FOR” the Proposals.

Table of Contents

How many votes do I have?

Each share of our Class A common stock and Class B common stock is entitled to one vote on each matter that comes before the Meeting. See the section below entitled “Beneficial Ownership of Securities” for information about the stock holdings of our Sponsor, directors and executive officers.

Is my vote kept confidential?

Proxies, ballots and voting tabulations identifying stockholders are kept confidential and will not be disclosed except as may be necessary to meet legal requirements.

What do I need to do now?

We urge you to read carefully and consider the information contained in this Proxy Statement, including the annexes, and to consider how the Proposals will affect you as our stockholder. You should then vote as soon as possible in accordance with the instructions provided in this Proxy Statement and on the enclosed proxy card.

What should I do if I receive more than one set of voting materials?

You may receive more than one set of voting materials, including multiple copies of this Proxy Statement and multiple proxy cards or voting instruction cards, if your shares are registered in more than one name or are registered in different accounts. 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. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your shares of the Company’s common stock.

Where do I find the voting results of the Meeting?

We will announce preliminary voting results at the Meeting. The final voting results will be tallied by the inspector of election and published in the Company’s Current Report on Form 8-K, which the Company is required to file with the SEC within four business days following the Meeting.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies from our working capital. We have engaged the Solicitation Agent to assist in the solicitation of proxies for the Meeting. We have agreed to pay the Solicitation Agent approximately $30,000 in connection with such services for the Meeting. We will also reimburse Solicitation Agent for reasonable out-of-pocket expenses and will indemnify the Solicitation Agent and its affiliates against certain claims, liabilities, losses, damages and expenses. In addition to these mailed proxy materials, our directors and officers may also solicit proxies in person, by telephone or by other means of communication. These parties will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners. While the payment of these expenses will reduce the cash available to us to consummate a Business Combination if the Extension is approved, we do not expect such payments to have a material effect on our ability to a Business Combination.

Who can help answer my questions?

FORWARD-LOOKING STATEMENTS

Some of the statements contained in this Proxy Statement constitute forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. Forward-looking statements reflect our current views with respect to, among other things, the pending Business Combination, our capital resources and results of operations. Likewise, our financial statements and all of our statements regarding market conditions and results of operations are forward-looking statements. In some cases, you can identify these forward-looking statements by the use of terminology such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates” or the negative version of these words or other comparable words or phrases.

The forward-looking statements contained in this Proxy Statement reflect our current views about future events and are subject to numerous known and unknown risks, uncertainties, assumptions and changes in circumstances that may cause our actual results to differ significantly from those expressed in any forward-looking statement. We do not guarantee that the transactions and events described will happen as described (or that they will happen at all). The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements:

• our ability to complete the Coincheck Business Combination;

• the anticipated benefits of the Coincheck Business Combination;

• the volatility of the market price and liquidity of our securities;

• the use of funds not held in the Trust Account;

• the competitive environment in which our successor will operate following the Coincheck Business Combination; and

• proposed changes in SEC rules related to special purpose acquisition companies (“SPACs”).

While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. We disclaim any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events or other changes after the date of this Proxy Statement, except as required by applicable law.

For a further discussion of these and other factors that could cause our future results, performance or transactions to differ significantly from those expressed in any forward-looking statement, please see the section below entitled “Risk Factors,” and in other reports we file with the SEC. You should not place undue reliance on any forward-looking statements, which are based only on information currently available to us (or to third parties making the forward-looking statements).

RISK FACTORS

You should consider carefully all of the risks described in our (i) IPO Prospectus, (ii) Quarterly Report on Form 10-Q for the quarter ended March 31, 2022, as filed with the SEC on May 16, 2022, (iii) Quarterly Report on Form 10-Q for the quarter ended June 30, 2022, as filed with the SEC on July 27, 2022, (iv) Quarterly Report on Form 10-Q for the quarter ended September 30, 2022, as filed with the SEC on November 14, 2022, (v) Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 31, 2023, and (vi) other reports we file with the SEC, before making a decision to invest in our securities. Furthermore, if any of the following events occur, our business, financial condition and operating results may be materially adversely affected or we could face liquidation. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties described in the aforementioned filings and below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business, financial condition and operating results or result in our liquidation.

There are no assurances that the Extension Amendment will enable us to complete a Business Combination.

Approving the Extension Amendment involves a number of risks. Even if the Extension Amendment is approved and implemented, the Company can provide no assurances that the Coincheck Business Combination or another initial Business Combination will be consummated prior to the Extended Date. Our ability to consummate any Business Combination is dependent on a variety of factors, many of which are beyond our control. If the Extension Amendment is approved and implemented, the Company plans to seek stockholder approval of the Business Combination following the SEC declaring the Registration Statement on Form F-4 to be filed by PubCo in connection with the Coincheck Business Combination (the “Coincheck Registration Statement”) effective, which will include our proxy statement for the Coincheck Business Combination. The Company cannot complete the Coincheck Business Combination unless the Coincheck Registration Statement is declared effective. As of the date of this Proxy Statement, a draft of the Coincheck Registration Statement has been confidentially submitted to the SEC, but the Company cannot estimate when, or if, the Coincheck Registration Statement will be filed with the SEC or when the SEC will declare the Coincheck Registration Statement effective.

We are required to offer stockholders the opportunity to redeem their Public Shares in connection with the Charter Amendment Proposals and, if needed, any additional amendments to the Charter, and we will be required to offer stockholders redemption rights again in connection with any stockholder vote to approve an initial Business Combination. Even if the Charter Amendment Proposals (or the Coincheck Business Combination) are approved by our stockholders, it is possible that redemptions will leave us with insufficient cash to consummate an initial Business Combination on commercially acceptable terms, or at all. The fact that we will have separate redemption periods in connection with the Extension Amendment and the Business Combination vote could exacerbate these risks. Other than in connection with a redemption offer or liquidation, our stockholders may be unable to recover their investment except through sales of our shares on the open market. The price of our shares may be volatile, and there can be no assurance that stockholders will be able to dispose of our shares at favorable prices, or at all.

If we are deemed to be an investment company for purposes of the Investment Company Act, we would be required to institute burdensome compliance requirements and our activities would be severely restricted. As a result, in such circumstances, unless we are able to modify our activities so that we would not be deemed an investment company, we may abandon our efforts to complete an initial Business Combination and instead liquidate the Company.

There is currently some uncertainty concerning the applicability of the Investment Company Act of 1940 (the “Investment Company Act”) to a SPAC, including a company like ours. As a result, it is possible that a claim could be made that we have been operating as an unregistered investment company.

If we are deemed to be an investment company under the Investment Company Act, our activities would be severely restricted. In addition, we would be subject to burdensome compliance requirements. We do not believe that our principal activities will subject us to regulation as an investment company under the Investment Company Act. However, if we are deemed to be an investment company and subject to compliance with and regulation under the Investment Company Act, we would be subject to additional regulatory burdens and expenses for which we have not allotted funds. As a result, unless we are able to modify our activities so that we would not be deemed an

Table of Contents

investment company, we may abandon our efforts to complete an initial Business Combination and instead liquidate the Company. Were we to liquidate, our warrants would expire worthless, and our securityholders would lose the investment opportunity associated with an investment in the combined company, including potential price appreciation of our securities.

To mitigate the risk that we might be deemed to be an investment company for purposes of the Investment Company Act, we have instructed the trustee to liquidate the investments held in the Trust Account, effective July 1, 2023, and instead to hold the funds in the Trust Account in an interest-bearing demand deposit account at a bank until the earlier of the consummation of our initial Business Combination or our liquidation. As a result, following the liquidation of investments in the Trust Account, we may receive less interest on the funds held in the Trust Account than the interest we would have received pursuant to our original Trust Account investments, which could reduce the dollar amount our public stockholders would receive upon any redemption or our liquidation.

The funds in the Trust Account have, since our initial public offering, been held only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds investing solely in U.S. government treasury obligations and meeting certain conditions under Rule 2a-7 under the Investment Company Act. However, to mitigate the risk of us being deemed to be an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act) and thus subject to regulation under the Investment Company Act, we have instructed Continental, the trustee with respect to the Trust Account, to liquidate the U.S. government treasury obligations or money market funds held in the Trust Account, effective July 1, 2023, and thereafter to hold all funds in the Trust Account in an interest-bearing demand deposit account at a bank until the earlier of the consummation of our initial Business Combination or the liquidation of the Company. Following such liquidation, we may receive less interest on the funds held in the Trust Account than the interest we would have received pursuant to our original Trust Account investments; however, interest previously earned on the funds held in the Trust Account still may be released to us to pay our taxes, if any, and certain other expenses as permitted. Consequently, the transfer of the funds in the Trust Account to an interest-bearing demand deposit account could reduce the dollar amount our public stockholders would receive upon any redemption or our liquidation.

In the event that we are deemed to be an investment company, despite the change in investments in the Trust Account, we may be required to liquidate the Company, and the longer the period before the investment change, the greater the risk of being considered an investment company.

BACKGROUND

We are a blank check company formed under the laws of the State of Delaware on January 7, 2021, for the purpose of effecting a Business Combination with one or more businesses.

There are currently 24,300,839 shares of our Class A common stock and 5,913,196 shares of Class B common stock issued and outstanding. In addition, we issued (i) Public Warrants to purchase 4,730,557 shares of Class A common stock as part of our IPO and (ii) warrants included in our Private Placement Units (the “Private Placement Warrants”) to purchase 129,611 shares of Class A common stock as part of the private placement with the Sponsor that we consummated simultaneously with the consummation of our IPO. Each whole warrant entitles its holder to purchase one share of Class A common stock at an exercise price of $11.50 per share. Each Private Placement Unit consists of one share of Class A common stock and one-fifth of one warrant. The warrants will become exercisable 30 days after the completion of our initial Business Combination and expire five years after the completion of our initial Business Combination or earlier upon redemption or liquidation. Once the warrants become exercisable, the Company may redeem the outstanding warrants at a price of $0.01 per warrant, if the last sale price of the Company’s Class A common stock equals or exceeds $18.00 per share for any 20 trading days within a 30 trading day period ending on the third business day before the Company sends the notice of redemption to the warrant holders. The Private Placement Warrants, however, are non-redeemable so long as they are held by the Sponsor or its permitted transferees.

As of May 26, 2023, approximately $243.5 million from our IPO and the simultaneous sale of the Private Placement Units is being held in our Trust Account in the United States maintained by Continental, acting as trustee, invested in U.S. “government securities,” within the meaning of Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in any open ended investment company that holds itself out as a money market fund selected by us meeting the conditions of Rule 2a-7 of the Investment Company Act, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the proceeds in the Trust Account as described below. However, to mitigate the risk that we might be deemed to be an investment company for purposes of the Investment Company Act, we have instructed Continental, the trustee with respect to the Trust Account, to liquidate the investments held in the Trust Account, effective July 1, 2023, and instead to hold the funds in the Trust Account in an interest bearing demand deposit account until the earlier of the consummation of our initial Business Combination or our liquidation. As a result, following the liquidation of investments in the Trust Account, we may receive less interest on the funds held in the Trust Account than the interest we would have received pursuant to our original Trust Account investments; however, interest previously earned on the funds held in the Trust Account still may be released to us to pay our taxes, if any, and certain other expenses as permitted. Consequently, the transfer of the funds in the Trust Account to an interest-bearing demand deposit account could reduce the dollar amount our public stockholders would receive upon any redemption or liquidation of the Company.

In order to finance transaction costs in connection with an intended initial Business Combination, the Sponsor has committed, in the form of a loan, up to $1,500,000 to be provided to us to fund our expenses relating to investigating and selecting a target business and other working capital requirements prior to our initial Business Combination. As of March 31, 2023, we had $226,000 outstanding amounts under such loan.

Proposed Business Combination with Coincheck

As previously announced in the Business Combination 8-K, the Company entered into a Business Combination Agreement with Coincheck, PubCo, HoldCo and Merger Sub. Pursuant to the Business Combination Agreement, subject to the terms and conditions set forth therein, (i) prior to the closing of the Coincheck Business Combination (the “Closing”), Monex Group, Inc., a Japanese joint stock company (kabushiki kaisha) (“Monex”), the sole shareholder of both PubCo and HoldCo, will cause PubCo and HoldCo to undergo a restructuring resulting in HoldCo holding 147,587,616 ordinary shares in the share capital of PubCo (“PubCo Ordinary Shares”) and then becoming PubCo’s direct, wholly owned subsidiary (the “PubCo Restructuring”); (ii) thereafter, Coincheck will, and PubCo will cause HoldCo to, implement a share exchange (kabushiki koukan) pursuant to which the ordinary share of Coincheck outstanding immediately prior to 12:01 a.m. Japan Time on the Closing date will be exchanged (the “Share Exchange”) for PubCo Ordinary Shares, causing Coincheck to become a direct, wholly owned subsidiary of HoldCo; (iii) immediately following the Share Exchange, PubCo will (a) convert its legal form, without ceasing to exist, from a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) to a public limited liability company (naamloze vennootschap) and (b) amend and restate its governing documents, which, as so amended

Table of Contents

and restated, will be the governing documents of PubCo until thereafter amended in accordance with the terms thereof and applicable law (the “PubCo Reorganization”); and (iv) following the effective time of the Share Exchange and on the date of the Closing, the Merger Sub, a wholly owned subsidiary of PubCo, will merge with and into the Company, with the Company continuing as the surviving corporation and a wholly owned subsidiary of PubCo (the “Merger”).

Prior to the Closing, the PubCo shareholders (the “Coincheck Shareholders”) will collectively deliver 25,000,000 shares of PubCo to an escrow agent (the “Escrowed Coincheck Shareholder Earn Out Shares”). The Escrowed Coincheck Shareholder Earn Out Shares will be released to the Coincheck Shareholders if the closing market price of PubCo Ordinary Shares is at or above $12.50 for 20 out of 30 consecutive trading days following the Closing. An additional 25,000,000 shares of PubCo (together with the Escrowed Company Shareholder Earn Out Shares, the “Coincheck Shareholder Earn Out Shares”) will be issued to the Coincheck Shareholders if the closing market price of PubCo Ordinary Shares is at or above $15.00 for 20 out of 30 consecutive trading days following the Closing. In the event such milestones are not met within five years of the Closing, the Escrowed Coincheck Shareholder Earn Out Shares will be automatically released to PubCo for repurchase for no consideration. In addition, at the Closing, the Sponsor will deliver to the escrow agent an aggregate of 2,365,278 PubCo Ordinary Shares that the Sponsor would otherwise receive as consideration in the Merger (the “Sponsor Earn Out Shares”). The Sponsor Earn Out Shares will be subject to the same milestones as the Coincheck Shareholder Earn Out Shares. In the event such milestones are not met within five years of the Closing, the Sponsor Earn Out Shares will be automatically released to PubCo for repurchase for no consideration.

In connection with the Closing, (i) each share of the Company’s common stock that is held by the Sponsor will be converted into one PubCo Ordinary Share and (ii) each share of Company’s common stock that is outstanding and has not been redeemed will be converted into a one PubCo Ordinary Share.

Each outstanding warrant to purchase the Company’s Class A common stock will become a warrant to purchase PubCo Ordinary Shares, with each such warrant exercisable for the number of PubCo Ordinary Shares the holder of such warrant would have received in the Merger if it exercised such immediately prior to the Merger.

For more information about the Coincheck Business Combination, see the Business Combination 8-K.

You are not being asked to vote on the Coincheck Business Combination at this time. If the Extension is implemented and you do not elect to redeem your Public Shares, provided that you are a stockholder on the record date for a meeting to consider the Coincheck Business Combination, you will retain the right to vote on the Coincheck Business Combination when it is submitted to stockholders and the right to redeem your Public Shares for cash in the event the Coincheck Business Combination is approved and completed or we have not consummated a Business Combination by the Extended Date.

If the Extension Amendment Proposal is approved, and the Extension is implemented, public stockholder may seek to redeem their Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares. As of May 26, 2023, based on funds in the Trust Account of approximately $243.5 million as of such date, the pro rata portion of the funds available in the Trust Account for the redemption of Public Shares was approximately $10.29 per Public Share (before taking into account the removal of the accrued interest in the Trust Account to pay our taxes). If you do not elect to redeem your Public Shares in connection with the Extension, you will retain the right to redeem your Public Shares in connection with any stockholder vote to approve a proposed Business Combination, or if the Company has not consummated a Business Combination, by the Extended Date.

PROPOSAL ONE — THE EXTENSION AMENDMENT PROPOSAL

Overview

The Company is proposing to amend its Charter to extend the date by which the Company has to consummate a Business Combination to the Extended Date so as to provide the Company with additional time to complete the Business Combination.

The Extension Amendment Proposal is required for the implementation of the Board’s plan to allow the Company more time to complete the Business Combination. A copy of the proposed amendment to the Charter of the Company is attached to this Proxy Statement in Annex A.

Reasons for the Extension Amendment Proposal

The Company’s Charter provides that the Company has until July 2, 2023 to complete an initial Business Combination. The purpose of the Extension Amendment is to allow the Company more time to complete the Coincheck Business Combination (or if the Coincheck Business Combination is not consummated, another initial Business Combination).

The IPO Prospectus and Charter provide that the affirmative vote of the holders of at least 65% of all outstanding shares of common stock, including the Founder Shares, is required to extend our corporate existence, except in connection with, and effective upon, consummation of a Business Combination. Additionally, our IPO Prospectus and Charter provide for all public stockholders to have an opportunity to redeem their Public Shares if our corporate existence is extended as described above. Because we believe that the Coincheck Business Combination would be in the best interests of our stockholders, and because we will not be able to conclude the Coincheck Business Combination within the Combination Period, the Board has determined to seek stockholder approval to extend the date by which we have to complete a Business Combination beyond July 2, 2023 to the Extended Date. We intend to hold another stockholder meeting prior to the Extended Date in order to seek stockholder approval of the Coincheck Business Combination.

We believe that the foregoing Charter provision was included to protect Company stockholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable Business Combination in the timeframe contemplated by the Charter.

If the Extension Amendment Proposal is Not Approved

Stockholder approval of the Extension Amendment is required for the implementation of our Board’s plan to extend the date by which we must consummate our initial Business Combination. Therefore, our Board will abandon and not implement the Extension Amendment unless our stockholders approve the Extension Amendment Proposal.

If the Extension Amendment Proposal is not approved and we do not consummate the Business Combination by July 2, 2023, as contemplated by our IPO Prospectus and in accordance with our Charter, 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 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 the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and the Board, liquidate and dissolve, subject, in the case of clauses (ii) and (iii) above, 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 our initial Business Combination by July 2, 2023. There will be no distribution from the Trust Account with respect to our warrants, which will expire worthless in the event of our winding up. In the event of a liquidation, our Sponsor and our officers and directors will not receive any monies held in the Trust Account as a result of their ownership of the Founder Shares or the Private Placement Units.

Table of Contents

If the Extension Amendment Proposal is Approved

If the Extension Amendment Proposal is approved, the Company will file an amendment to the Charter with the Secretary of State of the State of Delaware in the form set forth in Annex A hereto to extend the time it has to complete a Business Combination until the Extended Date. The Company will remain a reporting company under the Exchange Act and expects that its units, Public Shares and Public Warrants will remain publicly traded. The Company will then continue to work to consummate the Business Combination by the Extended Date.

You are not being asked to vote on the Business Combination at this time. If the Extension is implemented and you do not elect to redeem your Public Shares, provided that you are a stockholder on the record date for a meeting to consider the Business Combination, you will retain the right to vote on the Business Combination when it is submitted to stockholders and the right to redeem your Public Shares for cash in the event the Business Combination is approved and completed or we have not consummated a Business Combination by the Extended Date.

If the Extension Amendment Proposal is approved, and the Extension is implemented, the removal of the Withdrawal Amount from the Trust Account in connection with the Election will reduce the amount held in the Trust Account. The Company cannot predict the amount that will remain in the Trust Account if the Extension Amendment Proposal is approved and the amount remaining in the Trust Account may be significantly less than the approximately $243.5 million that was in the Trust Account as of May 26, 2023.

Redemption Rights

If the Extension Amendment Proposal is approved, and the Extension is implemented, each public stockholder may seek to redeem its Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares. As of May 26, 2023, based on funds in the Trust Account of approximately $243.5 million as of such date, the pro rata portion of the funds available in the Trust Account for the redemption of Public Shares was approximately $10.29 per Public Share (before taking into account the removal of the accrued interest in the Trust Account to pay our taxes). Holders of Public Shares who do not elect to redeem their Public Shares in connection with the Extension will retain the right to redeem their Public Shares in connection with any stockholder vote to approve a proposed Business Combination, or if the Company has not consummated a Business Combination by the Extended Date.

TO EXERCISE YOUR REDEMPTION RIGHTS, YOU MUST SUBMIT A REQUEST IN WRITING THAT WE REDEEM YOUR PUBLIC SHARES FOR CASH TO CONTINENTAL AT THE ADDRESS BELOW, AND, AT THE SAME TIME, ENSURE YOUR BANK OR BROKER COMPLIES WITH THE REQUIREMENTS IDENTIFIED ELSEWHERE HEREIN, INCLUDING DELIVERING YOUR SHARES TO THE TRANSFER AGENT PRIOR TO 5:00 P.M. EASTERN TIME ON JUNE 16, 2023.

In connection with tendering your shares for redemption, prior to 5:00 p.m. Eastern Time on June 16, 2023 (two business days before the Meeting), you must elect either to physically tender your stock certificates to Continental Stock Transfer & Trust Company, 1 State Street Plaza, 30th Floor, New York, New York 10004, Attn: SPAC Redemption Team, spacredemptions@continentalstock.com, or to deliver your shares to the transfer agent electronically using DTC’s DWAC system, which election would likely be determined based on the manner in which you hold your shares. The requirement for physical or electronic delivery prior to 5:00 p.m. Eastern Time on June 16, 2023 (two business days before the Meeting) ensures that a redeeming holder’s election is irrevocable once the Extension Amendment Proposal is approved. In furtherance of such irrevocable election, stockholders making the election will not be able to tender their shares after the vote at the Meeting.

Through the DWAC system, this electronic delivery process can be accomplished by the stockholder, whether or not the stockholder is a record holder or the stockholder’s shares are held in “street name,” by contacting the Company’s transfer agent or the stockholder’s broker and requesting delivery of the shares through the DWAC system. Delivering shares physically may take significantly longer. In order to obtain a physical stock certificate, a stockholder’s broker and/or clearing broker, DTC, and the Company’s transfer agent will need to act together to facilitate this request. There

Table of Contents

is a nominal cost associated with the above-referenced 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 $100 and the broker will determine whether or not to pass this cost on to the redeeming holder. It is the Company’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. The Company does not have any control over this process, the brokers or DTC, and it may take longer than two weeks to obtain a physical stock certificate. Such stockholders will have less time to make their investment decision than those stockholders that deliver their shares through the DWAC system. Stockholders who request physical stock certificates and wish to redeem may be unable to meet the deadline for tendering their shares before exercising their redemption rights and thus will be unable to redeem their shares.

Certificates that have not been tendered in accordance with these procedures prior to 5:00 p.m. Eastern Time on June 16, 2023 (two business days before the Meeting) will not be redeemed for cash held in the Trust Account on the redemption date. If a public stockholder tenders its shares and decides prior to the vote at the Meeting that it does not want to redeem its shares, the stockholder may withdraw the tender. If you delivered your shares for redemption to our transfer agent and decide prior to the vote at the Meeting not to redeem your Public Shares, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the address listed above. In the event that a public stockholder tenders shares and the Extension Amendment Proposal is not approved, these shares will not be redeemed and the physical certificates representing these shares will be returned to the stockholder promptly following the determination that the Extension Amendment Proposal will not be approved. The transfer agent will hold the certificates of public stockholders that make the election until such shares are redeemed for cash or returned to such stockholders.

If properly demanded, the Company will redeem each Public Share for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares. As of May 26, 2023, based on funds in the Trust Account of approximately $243.5 million as of such date, the pro rata portion of the funds available in the Trust Account for the redemption of Public Shares was approximately $10.29 per Public Share (before taking into account the removal of the accrued interest in the Trust Account to pay our taxes). The closing price of the Company’s Class A common stock on May 26, 2023 as reported on the Nasdaq Capital Market was $10.23.

If you exercise your redemption rights, you will be exchanging your shares of the Company’s Class A common stock for cash and will no longer own the shares. You will be entitled to receive cash for these shares only if you properly demand redemption and tender your stock certificate(s) to the Company’s transfer agent prior to 5:00 p.m. Eastern Time on June 16, 2023 (two business days before the Meeting). The Company anticipates that a public stockholder who tenders shares for redemption in connection with the vote to approve the Extension Amendment Proposal would receive payment of the redemption price for such shares soon after the completion of the Extension.

Vote Required for Approval

The affirmative vote by holders of at least 65% of the Company’s outstanding shares of common stock, including the Founder Shares, is required to approve the Extension Amendment Proposal. If the Extension Amendment Proposal is not approved, the Extension Amendment will not be implemented and, if the Business Combination has not been consummated during the Combination Period, the Company will be required by its Charter 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, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and the Board, liquidate and dissolve, subject, in the case of clauses (ii) and (iii) above, to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Stockholder approval of the Extension Amendment is required for the implementation of our Board’s plan to extend the date by which we must consummate our initial Business Combination. Therefore, our Board will abandon and not implement such amendment unless our stockholders approve the Extension Amendment Proposal. Notwithstanding stockholder approval of the Extension Amendment Proposal, our Board will retain the right to abandon and not implement the Extension Amendment at any time without any further action by our stockholders.

Table of Contents

The Sponsor and all of our directors, executive officers and their affiliates are expected to vote any common stock owned by them in favor of the Extension Amendment Proposal. On the Record Date, the Sponsor and our directors and executive officers of the Company and their affiliates beneficially owned and were entitled to vote an aggregate of 5,913,196 Founder Shares, 648,055 shares of Class A common stock underlying the Private Placement Units and 100,000 Public Shares, representing approximately 22% of the Company’s issued and outstanding shares of common stock.

Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will have the same effect as voting “AGAINST” the Extension Amendment Proposal.

Interests of the Sponsor and our Directors and Officers

When you consider the recommendation of our Board, you should keep in mind that the Sponsor, executive officers and members of our Board have interests that may be different from, or in addition to, your interests as a stockholder. These interests include, among other things:

• the fact that the Sponsor holds 5,913,196 Founder Shares and 648,055 Private Placement Units, all such securities beneficially owned by our Chief Executive Officer, all of which would expire worthless if the Coincheck Business Combination or another Business Combination is not consummated;

• the fact that the Sponsor holds a promissory note in the principal amount of up to $1,500,000 issued in connection with working capital loans made by the Sponsor, of which $226,000 was outstanding as of March 31, 2023;

• the fact that, unless the Company consummates the Coincheck Business Combination or another Business Combination, the Sponsor will not receive reimbursement for any out-of-pocket expenses incurred by it on behalf of the Company (none of such expenses were incurred that had not been reimbursed as of March 31, 2023) to the extent that such expenses exceed the amount of available proceeds not deposited in the Trust Account;

• the fact that, if the Trust Account is liquidated, including in the event we are unable to complete an initial Business Combination within the Combination Period, the Sponsor has agreed to indemnify us to ensure that the proceeds in the Trust Account are not reduced below $10.00 per Public Share, or such lesser per Public Share amount as is in the Trust Account on the liquidation date, by the claims of prospective target businesses with which we have entered into an acquisition agreement or claims of any third party for services rendered or products sold to us, but only if such a third party or target business has not executed a waiver of any and all rights to seek access to the Trust Account; and

• the fact that none of our officers or directors has received any cash compensation for services rendered to the Company, and all of the current members of our Board are expected to continue to serve as directors at least through the date of the meeting to vote on a proposed Business Combination and may even continue to serve following the Coincheck Business Combination and receive compensation thereafter.

The Board’s Reasons for the Extension Amendment Proposal and Its Recommendation

As discussed below, after careful consideration of all relevant factors, our Board has determined that the Extension Amendment is in the best interests of the Company and its stockholders. Our Board has approved and declared advisable the adoption of the Extension Amendment Proposal and recommends that you vote “FOR” such proposal.

Our Charter provides that the Company has until July 2, 2023 to complete the purposes of the Company including, but not limited to, effecting a Business Combination under its terms.

Our Charter states that if the Company’s stockholders approve an amendment to the Company’s Charter that would affect the substance or timing of the Company’s obligation to redeem 100% of the Company’s Public Shares if it does not complete a Business Combination before July 2, 2023, the Company will provide its public stockholders with the opportunity to redeem all or a portion of their Public Shares upon such approval at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares. We believe that this Charter provision was included to protect the Company stockholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable Business Combination in the timeframe contemplated by the Charter.

Table of Contents

In addition, the IPO Prospectus and Charter provide that the affirmative vote of the holders of at least 65% of all outstanding shares of common stock, including the Founder Shares, is required to extend our corporate existence, except in connection with, and effective upon the consummation of, a Business Combination. Because we continue to believe that a Business Combination would be in the best interests of our stockholders and because we will not be able to conclude a Business Combination within the permitted time period, the Board has determined to seek stockholder approval to extend the date by which we have to complete a Business Combination beyond July 2, 2023 to the Extended Date.

The Company is not asking you to vote on the Business Combination at this time. If the Extension is implemented and you do not elect to redeem your Public Shares, you will retain the right to vote on the Business Combination in the future and the right to redeem your Public Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares, in the event the Business Combination is approved and completed or the Company has not consummated another Business Combination by the Extended Date.

After careful consideration of all relevant factors, the Board determined that the Extension Amendment is in the best interests of the Company and its stockholders.

Recommendation of the Board

Our Board unanimously recommends that our stockholders vote “FOR” the approval of the Extension Amendment Proposal.

PROPOSAL TWO — THE FOUNDER SHARE AMENDMENT PROPOSAL

Overview

The Company is proposing to amend its Charter to allow the Company to provide for the right of a holder of Founder Shares to convert such shares into shares of Class A common stock on a one-for-one basis at any time and from time to time prior to the closing of a Business Combination at the election of the holder.

Upon conversion of the Founder Shares to Class A common stock, such Class A common stock so converted shall not be entitled to receive funds from the Trust Account through redemptions or otherwise pursuant to the terms of the Letter Agreement, dated June 29, 2021, entered into by and among the Company, each of its officers and directors and the Sponsor in connection with the IPO. Additionally, the Class A common stock converted from the Founder Shares will be subject to the same restrictions as Founder Shares before the conversion, including, among others, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial Business Combination as described in our IPO Prospectus. The shares of Class A common stock converted from Founder Shares will also be entitled to registration rights. A copy of the proposed amendment to the Charter of the Company is attached to this Proxy Statement in Annex A.

Reasons for the Founder Share Amendment Proposal

The Company’s Charter currently provides that the Founder Shares will automatically convert into Class A common stock on a one-for-one basis, upon the consummation of a Business Combination. The purpose of the Founder Share Amendment Proposal is to provide the holders of the Founder Shares with the flexibility to assist the Company in retaining investors and meeting the listing requirements of its Class A common stock if necessary or desirable in connection with the Extension and the consummation of the Business Combination by converting their Founder Shares into shares of Class A common stock, thereby increasing the number of shares of Class A common stock outstanding.

If the Founder Share Amendment Proposal Is Not Approved

If the Founder Share Amendment Proposal is not approved, the holders of the Founder Shares will not be able to convert such shares into Class A Ordinary Shares prior to the completion of a Business Combination. If the Founder Share Amendment Proposal is not approved, we believe it may reduce our flexibility to maintain a listing of our Class A common stock.

If the Founder Share Amendment Proposal Is Approved

The Founder Share Amendment is conditioned on the approval of the Extension Amendment Proposal. If both the Extension Amendment Proposal and the Founder Share Amendment Proposal are approved, we will file an amendment to the Charter with the Secretary of State of the State of Delaware in the form set forth in Annex A hereto. The Company will remain a reporting company under the Exchange Act, and expects that its units, Public Shares and Public Warrants will remain publicly traded.

Additionally, if the Founder Share Amendment Proposal is approved and implemented, the Sponsor plans to convert on a one-for-one basis 5,913,195 Founder Shares held by the Sponsor into 5,913,195 shares of Class A common stock, and following the Founder Conversion, the Sponsor will continue to own one share of Class B common stock. The shares of Class A common stock that will be issued to the Sponsor in connection with the Founder Conversion will be subject to the same restrictions as shares of Class B common stock before the Founder Conversion, including, among others, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial Business Combination as described in our IPO Prospectus. The shares of Class A common stock that will be issued to the Sponsor in connection with the Founder Conversion will also be entitled to registration rights.

However, notwithstanding stockholder approval of the Charter Amendment Proposals, our Board will retain the right to abandon and not implement the Charter Amendments at any time without any further action by our stockholders.

Table of Contents

Vote Required for Approval

The approval of the Founder Share Amendment Proposal will require the affirmative vote of holders of at least 50% of our outstanding shares of common stock, including the Founder Shares, on the Record Date. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will have the same effect as voting “AGAINST” the Founder Share Amendment Proposal.

The Sponsor and all of the Company’s directors, executive officers and their affiliates are expected to vote any shares of common stock owned by them in favor of the Founder Share Amendment Proposal.

Recommendation of the Board

After careful consideration of all relevant factors, our Board has determined that the Founder Share Amendment is in the best interests of the Company and its stockholders. Our Board has approved and declared advisable the adoption of the Founder Share Amendment Proposal.

Our Board recommends a vote “FOR” the Founder Share Amendment Proposal.

PROPOSAL THREE — THE AUDITOR RATIFICATION PROPOSAL

We are asking the stockholders to ratify the Audit Committee’s selection of Grant Thornton, as our independent registered public accounting firm for the fiscal year ending December 31, 2023. Grant Thornton has audited our financial statements for the fiscal year ended December 31, 2022 and the period from January 7, 2021 (Date of inception) through December 31, 2021. A representative of Grant Thornton is not expected to be present at the Meeting; however, if a representative is present, they will have the opportunity to make a statement if they desire to do so and are not expected to be available to respond to appropriate questions. The following is a summary of fees paid or to be paid to Grant Thornton for services rendered.

Audit Fees

Audit fees consist of fees for professional services rendered for the audit of our year-end financial statements and services that are normally provided by Grant Thornton in connection with regulatory filings. The aggregate fees of Grant Thornton for professional services rendered for the audit of our annual financial statements, review of the financial information included in our Forms 10-Q for the respective periods and other required filings with the SEC for the period for the year ended December 31 2022 and from January 7, 2021 (date of inception) to December 31, 2021 totaled approximately $47,250 and $36,750, respectively. The above amounts include interim procedures and audit fees, as well as attendance at audit committee meetings.

Audit-Related Fees

Audit-related fees consist of fees billed for assurance and related services that are reasonably related to performance of the audit or review of our financial statements and are not reported under “Audit Fees.” These services include attest services that are not required by statute or regulation and consultations concerning financial accounting and reporting standards. During the year ended December 31, 2022 and for the period from January 7, 2021 (date of inception) to December 31, 2021 audit-related fees paid or payable to Grant Thornton totaled $825,000 and $0, respectively.

Tax Fees

We did not pay Grant Thornton for tax services, planning or advice for the year ended December 31, 2022 and for the period from January 7, 2021 (date of inception) to December 31, 2021.

All Other Fees

We did not pay Grant Thornton for other services for the year ended December 31, 2022 and for the period from January 7, 2021 (date of inception) to December 31, 2021.

Our Audit Committee has determined that the services provided by Grant Thornton are compatible with maintaining the independence of Grant Thornton as our independent registered public accounting firm.

Pre-Approval Policy

Our Audit Committee was formed upon the consummation of our IPO. As a result, the Audit Committee may not have pre-approved all of the foregoing services, although any services rendered prior to the formation of our Audit Committee were approved by our Board. Since the formation of our Audit Committee, and on a going-forward basis, the Audit Committee has and will pre-approve all auditing services and permitted non-audit services to be performed for us by Grant Thornton, including the fees and terms thereof (subject to the de minimis exceptions for non-audit services described in the Exchange Act which are approved by the Audit Committee prior to the completion of the audit).

Table of Contents

Consequences if the Auditor Ratification Proposal is Not Approved

The Audit Committee is directly responsible for appointing the Company’s independent registered public accounting firm. The Audit Committee is not bound by the outcome of this vote. However, if the stockholders do not ratify the selection of Grant Thornton as our independent registered public accounting firm for the fiscal year ending December 31, 2023, our Audit Committee may reconsider the selection of Grant Thornton as our independent registered public accounting firm.

Vote Required for Approval

The ratification of the appointment of Grant Thornton requires the vote of a majority of the votes cast by stockholders present (including virtually) or represented by proxy and entitled to vote on the matter at the Meeting. All holders of the Company’s common stock are entitled to vote on this proposal. Abstentions will have no effect on this proposal. If you do not want the Auditor Ratification Proposal approved, you must vote “AGAINST” the Auditor Ratification Proposal. Broker non-votes will count as votes cast on the Auditor Ratification Proposal.

Recommendation of the Board

Our Board recommends a vote “FOR” the ratification of the selection of Grant Thornton LLP by the Audit Committee as the Company’s independent registered public accounting firm.

Recommendation of the Board

Our Board unanimously recommends that our stockholders vote “FOR” the approval of the Adjournment Proposal.

Table of Contents

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of certain United States federal income tax considerations for holders of our Class A common stock with respect to the exercise of redemption rights in connection with the approval of the Extension Amendment Proposal. This summary is based upon the Internal Revenue Code of 1986, as amended (the “Code”), the regulations promulgated by the Treasury Department, current administrative interpretations and practices of the Internal Revenue Service (the “IRS”), and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. No assurance can be given that the IRS would not assert, or that a court would not sustain a position contrary to any of the tax considerations described below.

This summary does not discuss all aspects of United States federal income taxation that may be important to particular investors in light of their individual circumstances, such as investors (i) subject to special tax rules (e.g., financial institutions, insurance companies, mutual funds, pension plans, S corporations, broker-dealers, traders in securities that elect mark-to-market treatment, regulated investment companies, real estate investment trusts, trusts and estates, partnerships and their partners, and tax-exempt organizations (including private foundations)), (ii) that will hold Class A common stock as part of a “straddle,” “hedge,” “conversion,” “synthetic security,” “constructive ownership transaction,” “constructive sale,” or other integrated transaction for United States federal income tax purposes, (iii) subject to the applicable financial statement accounting rules of Section 451(b) of the Code, (iv) subject to the alternative minimum tax provisions of the Code, U.S. Holders (as defined below) that have a functional currency other than the United States dollar, U.S. expatriates, (v) that actually or constructively own five percent or more of the Class A common stock of the Company, and (vi) that are Non-U.S. Holders (as defined below, and except as otherwise discussed below), all of whom may be subject to tax rules that differ materially from those summarized below. In addition, this summary does not discuss any state, local, or non-United States tax considerations, any non-income tax (such as gift or estate tax) considerations, alternative minimum tax or the Medicare tax. In addition, this summary is limited to investors that hold our Class A common stock as “capital assets” (generally, property held for investment) under the Code.

If a partnership (including an entity or arrangement treated as a partnership for United States federal income tax purposes) holds our Class A common stock, the tax treatment of a partner in such partnership will generally depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. If you are a partner of a partnership holding our Class A common stock, you are urged to consult your tax advisor regarding the tax consequences of a redemption.

WE URGE HOLDERS OF OUR CLASS A COMMON STOCK CONTEMPLATING EXERCISE OF THEIR REDEMPTION RIGHTS TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE UNITED STATES FEDERAL, STATE, LOCAL, AND FOREIGN INCOME AND OTHER TAX CONSEQUENCES THEREOF.

U.S. Federal Income Tax Considerations to U.S. Holders

This section is addressed to U.S. Holders of the Company’s Class A common stock that elect to have their Class A common stock of the Company redeemed for cash. For purposes of this discussion, a “U.S. Holder” is a beneficial owner that so redeems its Class A common stock of the Company and is:

• an individual who is a United States citizen or resident of the United States;

• a corporation (including an entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

• an estate the income of which is includible in gross income for United States federal income tax purposes regardless of its source; or

• a trust (A) the administration of which is subject to the primary supervision of a United States court and which has one or more United States persons (within the meaning of the Code) who have the authority to control all substantial decisions of the trust or (B) that has in effect a valid election under applicable the Treasury Department regulations to be treated as a United States person.

Table of Contents

Redemption of Class A Common Stock

In the event that a U.S. Holder’s Class A common stock of the Company is redeemed, the treatment of the transaction for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of the Class A common stock under Section 302 of the Code. Whether the redemption qualifies for sale treatment will depend largely on the total number of shares of the Company’s stock treated as held by the U.S. Holder (including any stock constructively owned by the U.S. Holder as a result of owning warrants) relative to all of the Company’s shares both before and after the redemption. The redemption of Class A common stock generally will be treated as a sale of the Class A common stock (rather than as a distribution) if the redemption (i) is “substantially disproportionate” with respect to the U.S. Holder, (ii) results in a “complete termination” of the U.S. Holder’s interest in us or (iii) is “not essentially equivalent to a dividend” with respect to the U.S. Holder. These tests are explained more fully below.

In determining whether any of the foregoing tests are satisfied, a U.S. Holder takes into account not only stock actually owned by the U.S. Holder, but also shares of the Company’s stock that are constructively owned by it. A U.S. Holder may constructively own, in addition to stock owned directly, stock owned by certain related individuals and entities in which the U.S. Holder has an interest or that have an interest in such U.S. Holder, as well as any stock the U.S. Holder has a right to acquire by exercise of an option, which would generally include Class A common stock that could be acquired pursuant to the exercise of the warrants. In order to meet the substantially disproportionate test, the percentage of the Company’s outstanding voting stock actually and constructively owned by the U.S. Holder immediately following the redemption of Class A common stock must, among other requirements, be less than 80% of the Company’s outstanding voting stock actually and constructively owned by the U.S. Holder immediately before the redemption. There will be a complete termination of a U.S. Holder’s interest if either (i) all of the shares of the Company’s stock actually and constructively owned by the U.S. Holder are redeemed or (ii) all of the shares of the Company’s stock actually owned by the U.S. Holder are redeemed and the U.S. Holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of stock owned by certain family members and the U.S. Holder does not constructively own any other stock. The redemption of the Class A common stock will not be essentially equivalent to a dividend if a U.S. Holder’s conversion results in a “meaningful reduction” of the U.S. Holder’s proportionate interest in the Company. Whether the redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in the Company will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.”

If none of the foregoing tests are satisfied, then the redemption will be treated as a distribution and the tax effects will be as described in the subsection below entitled “U.S. Federal Income Tax Considerations to U.S. Holders — Taxation of Distributions.”

U.S. Holders of the Company’s Class A common stock considering exercising their redemption rights should consult their own tax advisors as to whether the redemption of their Class A common stock of the Company will be treated as a sale or as a distribution under the Code.

Gain or Loss on a Redemption of Class A Common Stock Treated as a Sale

If the redemption qualifies as a sale of Class A common stock, a U.S. Holder must treat any gain or loss recognized as capital gain or loss. Any such capital gain or loss will be long-term capital gain or loss if the U.S. Holder’s holding period for the Class A common stock so disposed of exceeds one year. Generally, a U.S. Holder will recognize gain or loss in an amount equal to the difference between (i) the amount of cash received in such redemption (or, if the Class A common stock is held as part of a unit at the time of the disposition, the portion of the amount realized on such disposition that is allocated to the Class A common stock based upon the then fair market values of the Class A common stock and the three-quarters of one warrant included in the unit) and (ii) the U.S. Holder’s adjusted tax basis in its Class A common stock so redeemed. A U.S. Holder’s adjusted tax basis in its Class A common stock generally will equal the U.S. Holder’s acquisition cost (that is, the portion of the purchase price of a unit allocated to a share of Class A common stock or the U.S. Holder’s initial basis for Class A common stock received upon exercise of a whole warrant) less any prior distributions treated as a return of capital. Long-term capital gain realized by a non-corporate U.S. Holder generally will be taxable at a reduced rate. The deduction of capital losses is subject to limitations.

Table of Contents

Taxation of Distributions

If the redemption does not qualify as a sale of Class A common stock, the U.S. Holder will be treated as receiving a distribution. In general, any distributions to U.S. Holders will constitute dividends for United States federal income tax purposes to the extent paid from the Company’s current or accumulated earnings and profits, as determined under United States federal income tax principles. Distributions in excess of current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. Holder’s adjusted tax basis in the Company’s Class A common stock. Any remaining excess will be treated as gain realized on the sale or other disposition of the Class A common stock and will be treated as described in the subsection above entitled “U.S. Federal Income Tax Considerations to U.S. Holders — Gain or Loss on a Redemption of Class A Common Stock Treated as a Sale.” Dividends the Company pays to a U.S. Holder that is a taxable corporation generally will qualify for the dividends received deduction if the requisite holding period is satisfied. With certain exceptions, and provided certain holding period requirements are met, dividends the Company pays to a non-corporate U.S. Holder generally will constitute “qualified dividends” that will be taxable at a reduced rate.

U.S. Federal Income Tax Considerations to Non-U.S. Holders

This section is addressed to Non-U.S. Holders of the Company’s Class A common stock that elect to have their Class A common stock redeemed for cash. For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner (other than a partnership) that so redeems its Class A common stock of the Company and is not a U.S. Holder.

Redemption of Class A Common Stock

The characterization for United States federal income tax purposes of the redemption of a Non-U.S. Holder’s Class A common stock generally will correspond to the United States federal income tax characterization of such a redemption of a U.S. Holder’s Class A common stock, as described in the subsection above entitled “U.S. Federal Income Tax Considerations to U.S. Holders.”

Non-U.S. Holders of the Company’s Class A common stock considering exercising their redemption rights should consult their own tax advisors as to whether the redemption of their Class A common stock will be treated as a sale or as a distribution under the Code.

Gain or Loss on a Redemption of Class A Common Stock Treated as a Sale

If the redemption qualifies as a sale of Class A common stock, a Non-U.S. Holder generally will not be subject to United States federal income or withholding tax in respect of gain recognized on a sale of its Class A common stock of the Company, unless:

• the gain is effectively connected with the conduct of a trade or business by the Non-U.S. Holder within the United States (and, under certain income tax treaties, is attributable to a United States permanent establishment or fixed base maintained by the Non-U.S. Holder), in which case the Non-U.S. Holder will generally be subject to the same treatment as a U.S. Holder with respect to the redemption, and a corporate Non-U.S. Holder may be subject to the branch profits tax at a 30% rate (or lower rate as may be specified by an applicable income tax treaty);

• the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year in which the redemption takes place and certain other conditions are met, in which case the Non-U.S. Holder will be subject to a 30% tax on the individual’s net capital gain for the year; or

• the Company is or has been a “U.S. real property holding corporation” for United States federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the period that the Non-U.S. Holder held the Company’s Class A common stock, and, in the case where shares of the Company’s Class A common stock are regularly traded on an established securities market, the Non-U.S. Holder has owned, directly or constructively, more than 5% of the Company’s Class A common stock at any time within the shorter of the five-year period preceding the disposition or such Non-U.S. Holder’s holding period for the shares of the Company’s Class A common stock. We do not believe the Company is or has been a U.S. real property holding corporation.

Table of Contents

Taxation of Distributions

If the redemption does not qualify as a sale of Class A common stock, the Non-U.S. Holder will be treated as receiving a distribution. In general, any distributions the Company makes to a Non-U.S. Holder of shares of the Company’s Class A common stock, to the extent paid out of the Company’s current or accumulated earnings and profits (as determined under United States federal income tax principles), will constitute dividends for U.S. federal income tax purposes and, provided such dividends are not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States, the Company will be required to withhold tax from the gross amount of the dividend at a rate of 30%, unless such Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate. Any distribution not constituting a dividend will be treated first as reducing (but not below zero) the Non-U.S. Holder’s adjusted tax basis in its shares of the Company’s Class A common stock and, to the extent such distribution exceeds the Non-U.S. Holder’s adjusted tax basis, as gain realized from the sale or other disposition of the Class A common stock, which will be treated as described above in the subsection entitled “U.S. Federal Income Tax Considerations to Non-U.S. Holders — Gain on Sale, Taxable Exchange or Other Taxable Disposition of Class A Common Stock.” Dividends the Company pays to a Non-U.S. Holder that are effectively connected with such Non-U.S. Holder’s conduct of a trade or business within the United States generally will not be subject to United States withholding tax, provided such Non-U.S. Holder complies with certain certification and disclosure requirements. Instead, such dividends generally will be subject to United States federal income tax, net of certain deductions, at the same graduated individual or corporate rates applicable to U.S. Holders (subject to an exemption or reduction in such tax as may be provided by an applicable income tax treaty). If the Non-U.S. Holder is a corporation, dividends that are effectively connected income may also be subject to a “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty).

As previously noted above, the foregoing discussion of certain material U.S. federal income tax consequences is included for general information purposes only and is not intended to be, and should not be construed as, legal or tax advice to any stockholder. We once again urge you to consult with your own tax adviser to determine the particular tax consequences to you (including the application and effect of any U.S. federal, state, local or foreign income or other tax laws) of the receipt of cash in exchange for shares in connection with the Charter Amendment Proposals.

STOCKHOLDER PROPOSALS

We anticipate that our annual meeting of stockholders for the 2023 fiscal year (the “2023 Annual Meeting”) will be held no later than December 31, 2024. For any proposal to be considered for inclusion in our proxy statement and form of proxy for submission to the stockholders at the 2023 Annual Meeting, it must be submitted in writing and comply with the requirements of Rule 14a-8 of the Exchange Act and our bylaws. Such proposals must be received at our offices at 9912 Georgetown Pike, Suite D203, Great Falls, Virginia 22066 no later than March 26, 2024.

In addition, our bylaws provide notice procedures for our stockholders to nominate a person as a director and to propose business to be considered by stockholders at a meeting. Notice of a nomination or proposal must be delivered to us not less than 90 days and not more than 120 days prior to the anniversary date for the preceding year’s annual meeting of stockholders; provided, however, that in the event that the annual meeting is called for a date that is more than 30 days before or more than 60 days after such anniversary date, notice by the stockholder to be timely must be so received no earlier than the close of business on the 120th day before the meeting and not later than the later of (i) the close of business on the 90th day before the meeting or (ii) the close of business on the 10th day following the day on which public announcement of the date of the annual meeting is first made by us. Accordingly, for the 2023 Annual Meeting, assuming the meeting is held on or about June 21, 2024, notice of a nomination or proposal must be delivered to us no later than March 26, 2024 and no earlier than February 25, 2024. Nominations and proposals also must satisfy other requirements set forth in the bylaws. The Chairman of the Board may refuse to acknowledge the introduction of any stockholder proposal not made in compliance with the foregoing procedures.

If the Extension Amendment Proposal is not approved, we will not hold a 2023 Annual Meeting.

HOUSEHOLDING INFORMATION

Unless we have received contrary instructions, we may send a single copy of this Proxy Statement to any household at which two or more stockholders reside if we believe the stockholders are members of the same family. This process, known as “householding,” reduces the volume of duplicate information received at any one household and helps to reduce our expenses. However, if as stockholders as of the Record Date, you and members of your family who reside at the same address prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, you should follow the instructions described below. Similarly, if you share an address with another stockholder and together both of you would like to receive only a single set of our disclosure documents, you should follow these instructions:

• If the shares are registered in your names, you should contact us at (202) 431-0507 or 9912 Georgetown Pike, Suite D203, Great Falls, Virginia 22066, to inform us of your request; or

• If a bank, broker or other nominee holds your shares, you should contact the bank, broker or other nominee directly.
