PROXY STATEMENT FOR SPECIAL MEETING

OF STOCKHOLDERS OF

ALTENERGY ACQUISITION CORP.

Stockholders of AltEnergy Acquisition Corp.:

You are cordially invited to attend the special meeting (the “Special Meeting”) of stockholders of AltEnergy Acquisition Corp., a Delaware corporation (the “Company,” “AltEnergy,” “we,” “us” or “our”), to be held on April 16, 2024, at 10:00AM Eastern Time or at such other time, on such other date and at such other place to which the meeting may be postponed or adjourned. The Special Meeting will be a completely virtual meeting of stockholders, which will be conducted by live webcast. You will be able to attend the Special Meeting online, vote, and submit your questions during the Special Meeting by visiting https://www.cstproxy.com/altenergyacquisition/2024. The accompanying proxy statement is dated March 27, 2024, and is first being mailed to stockholders of the Company on or about April 2, 2024.

Even if you are planning on attending the Special Meeting online, please promptly submit your proxy vote by completing, dating, signing and returning the enclosed proxy, so that your shares will be represented at the Special Meeting. It is strongly recommended that you complete and return your proxy card before the Special Meeting date to ensure that your shares will be represented at the Special Meeting. Instructions on how to vote your shares are on the proxy materials you received for the Special Meeting.

The Special Meeting is being held to consider and vote upon the following proposals:

(a)

a proposal to amend the Company’s Amended and Restated Certificate of Incorporation (the “Charter”) in the form set forth in Annex A of the accompanying proxy statement to extend the date by which the Company must (1) consummate a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (an “initial business combination”) or (2) cease its operations except for the purpose of winding up if it fails to complete such initial business combination, and redeem all of the Class A common stock, par value $0.0001 per share, of the Company (“Class A Common Stock” or “public shares”), included as part of the units sold in the Company’s initial public offering that was consummated on November 2, 2021 (the “IPO”), from May 2, 2024, to November 2, 2024 (the “Extended Date”) and to allow the board of directors of the Company (the “Board”), without another stockholder vote, to elect to further extend the date to consummate an initial business combination after the Extended Date up to six times, by an additional month each time, upon two days’ advance notice prior to the applicable deadline, up to May 2, 2025 (the “Additional Extension Date” and together with the Extended Date the “Extension” and such proposal, the “Extension Proposal”);

(b)

as a special resolution, to amend the Charter pursuant to an amendment to the Charter in the form set forth in Annex A of the accompanying proxy statement (the “Redemption Limitation Amendment” and such proposal, the “Redemption Limitation Amendment Proposal”) to eliminate from the Charter the limitation that the Company shall not redeem Class A Common Stock included as part of the units sold in the IPO (including any shares issued in exchange thereof, the “public shares”) to the extent that such redemption would cause the Company’s net tangible assets to be less than $5,000,001 following such redemptions (the “Redemption Limitation”). The Redemption Limitation Amendment would allow the

Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation; and

(c)

a proposal to approve the adjournment of the Special Meeting to a later date or dates, if necessary or convenient, 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 Extension Proposal (the “Adjournment Proposal”), which will only be presented at the Special Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Special Meeting to approve the Extension Proposal, in which case the Adjournment Proposal will be the only proposal presented at the Special Meeting.

Each of the Extension Proposal, the Redemption Limitation Amendment Proposal and the Adjournment Proposal is more fully described in the accompanying proxy statement, which you are encouraged to read carefully.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE EXTENSION PROPOSAL AND, IF PRESENTED, THE ADJOURNMENT PROPOSAL.

The purpose of the Extension Proposal is to allow the Company more time to complete its previously announced business combination (the “Business Combination”) with Car Tech, LLC, an Alabama limited liability company (“Car Tech”). On February 21, 2024, the Company entered into that certain Agreement and Plan of Merger (as it may be amended from time to time, the “Merger Agreement”) with Car Tech Merger Sub, LLC, a Delaware limited liability company and wholly-owned subsidiary of the Company (“Merger Sub”), and Car Tech, pursuant to which Merger Sub will merge with and into Car Tech, with Car Tech as the surviving entity and a wholly owned subsidiary of the Company.

The Charter provides that the Company has until May 2, 2024, to complete an initial business combination. While the Company and the other parties to the Merger Agreement are working toward satisfaction of the conditions to completion of the Business Combination, the Board has determined that there may not be sufficient time before May 2, 2024 to complete the Business Combination. Therefore, the Board has determined that it is in the best interests of the Company’s stockholders to extend the date by which the Company has to complete an initial business combination to the Extended Date or the Additional Extension Date, as applicable. If the Extension Proposal is approved, the Company plans to hold another stockholder meeting prior to the Extended Date or the Additional Extension Date, as applicable, in order to seek stockholder approval of the Business Combination and related proposals. For more information regarding the Business Combination and the Merger Agreement, please read the Company’s Current Report on Form 8-K relating to the Business Combination that was filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 21, 2024, including the complete text of the Merger Agreement provided as an exhibit thereto.

The purpose of the Redemption Limitation Amendment Proposal is to eliminate from the Charter the Redemption Limitation. Unless the Redemption Limitation Amendment Proposal is approved, the Company will not proceed with the Extension if redemptions of its public shares would cause the Company to exceed the Redemption Limitation. If the Redemption Limitation Amendment Proposal is not approved and there are significant requests for redemption such that the Redemption Limitation would be exceeded, the Redemption Limitation would prevent the Company from being able to consummate the Business Combination. The Company believes that the Redemption Limitation is not needed. The purpose of such limitation was initially to ensure that the Company did not become subject to the SEC’s “penny stock” rules. Because the public shares would not be deemed to be “penny stock” as such securities are listed on a national securities exchange, the Company is presenting the Redemption Limitation Amendment Proposal to facilitate the consummation of the Business Combination. If the Redemption Limitation Amendment Proposal is not approved and there are significant requests for redemption such that the Company’s net tangible assets would be less than $5,000,001 upon the consummation of the Business Combination, the Charter would prevent the Company from being able to consummate the Business Combination even if all other conditions to closing are met.

further solicitation and vote of proxies in the event that there are insufficient votes to approve the Extension Proposal and/or the Redemption Limitation Amendment Proposal or if the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the other proposals.

In connection with the Extension, holders of public shares (“public stockholders”) may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account established in connection with the IPO (the “Trust Account”), including interest earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable), divided by the number of then-issued and outstanding shares of Class A Common Stock, regardless of how such public stockholders vote on the Extension Proposal or if they vote at all. If the Extension Proposal is approved by the requisite vote of stockholders, the remaining public stockholders will retain their right to redeem their shares of Class A Common Stock upon consummation of the Business Combination when it is submitted to a vote of the stockholders, subject to any limitations set forth in the Charter, as amended. In addition, public stockholders will be entitled to have their shares redeemed for cash if the Company has not completed an initial business combination by the Extended Date or the Additional Extension Date, as applicable.

Based upon the amount held in the Trust Account as of February 29, 2024, which was $17,742,606.82, and estimated interest income and taxes post-February 29, 2024, the Company estimates that the per-share price at which public shares may be redeemed from cash held in the Trust Account will be approximately $11.20 at the time of the Special Meeting. The closing price of a share of Class A Common Stock on March 22, 2024, was $11.25. The Company cannot assure stockholders that they will be able to sell their 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.

Pursuant to the Charter, a public stockholder may request that the Company redeem all or a portion of such public stockholder’s public shares for cash if either the Extension Proposal or the Redemption Limitation Amendment Proposal is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

(i)

(a) hold public shares or (b) hold public shares as part of units and elect to separate such units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

(ii)

prior to 5:00 p.m., Eastern Time, on April 11, 2024 (two business days prior to the vote at the Special Meeting), (a) submit a written request to Continental Stock Transfer & Trust Company, the Company’s transfer agent, that the Company redeem your public shares for cash and (b) deliver your public shares to the transfer agent, physically or electronically through The Depository Trust Company.

Holders of units of the Company must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, his or her own name, the holder must contact the transfer agent directly and instruct it to do so. Public stockholders may elect to redeem all or a portion of their public shares even if they vote for the Extension Proposal and/or the Redemption Limitation Amendment Proposal.

If the Extension is not approved and we do not consummate the Business Combination by May 2, 2024, 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 subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining public

stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the Delaware General Corporation Law (the “DGCL”) to provide for claims of creditors and other requirements of 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 May 2, 2024 or by the applicable deadline as may be extended.

Approval of the Extension Proposal and the Redemption Limitation Amendment Proposal requires the affirmative vote of the holders of at least 65% of the Class A Common Stock and Class B common stock, par value $0.0001 per share, of the Company issued to the Sponsor in a private placement prior to the IPO (“Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”) issued and outstanding, voting together as a single class, represented in person or by proxy and entitled to vote thereon.

The Board has fixed the close of business on March 5, 2024, as the record date for the Special Meeting. Only stockholders of record on March 5, 2024, are entitled to notice of and to vote at the Special Meeting or any postponement or adjournment thereof. Further information regarding voting rights and the matters to be voted upon is presented in the accompanying proxy statement.

You are not being asked to vote on an initial business combination, including the Business Combination at this time. If the Extension is implemented and you do not elect to redeem your public shares in connection with the Extension, you will retain the right to vote on an initial business combination if and when such transaction is submitted to stockholders and the right to redeem your public shares for cash from the Trust Account in the event a proposed initial business combination is approved and completed or the Company has not consummated an initial business combination by the Extended Date or the Additional Extension Date, as applicable. If an initial business combination is not consummated by the Extended Date or the Additional Extension Date, as applicable, assuming the Extension is implemented, and the Company does not obtain an additional extension, the Company will redeem its public shares.

All Company stockholders are cordially invited to attend the Special Meeting via the Internet at https://www.cstproxy.com/altenergyacquisition/2024. To ensure your representation at the Special Meeting, however, you are urged to complete, sign, date and return your proxy card as soon as possible. If your shares are held in an account at a brokerage firm or bank, you must instruct your broker or bank on how to vote your shares. You may revoke your proxy card at any time prior to the Special Meeting.

A stockholder’s failure to vote in person or by proxy will not be counted towards the number of Common Stock required to validly establish a quorum. Abstentions will be counted in connection with the determination of whether a valid quorum is established.

YOUR VOTE IS IMPORTANT. Please sign, date and return your proxy card as soon as possible. You are requested to carefully read the proxy statement and accompanying Notice of Special Meeting for a more complete statement of matters to be considered at the Special Meeting.

If you have any questions or need assistance voting your Common Stock, please contact Jon Darnell by calling 203-299-1400, or by emailing info@altenergyacquisition.com.

On behalf of our board of directors, we would like to thank you for your support of AltEnergy Acquisition Corp.

The Special Meeting will be held to consider and vote upon the following proposals:

Proposal No. 2—The Redemption Limitation Amendment Proposal—as a special resolution, to amend the Charter pursuant to an amendment to the Charter in the form set forth in Annex A of the accompanying proxy statement (the “Redemption Limitation Amendment” and such proposal, the “Redemption Limitation Amendment Proposal”) to eliminate from the Charter the limitation that the Company shall not redeem the shares of Class A Common Stock included as part of the units sold in the IPO (including any shares issued in exchange thereof, the “public shares”) to the extent that such redemption would cause the Company’s net tangible assets to be less than $5,000,001 following such redemptions (the “Redemption Limitation”).

The above matters are more fully described in the accompanying proxy statement. We urge you to read carefully the accompanying proxy statement in its entirety.

liability company (“Car Tech”). On February 21, 2024, the Company entered into that certain Agreement and Plan of Merger (as it may be further amended from time to time, the “Merger Agreement”) with Car Tech Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“Merger Sub”), and Car Tech, pursuant to which Merger Sub will merge with and into Car Tech, with Car Tech as the surviving entity and a wholly owned subsidiary of the Company. Approval of the Extension Proposal is a condition to the implementation of the Extension.

The purpose of the Adjournment Proposal is to allow the Company to adjourn the Special Meeting to a later date or dates, if necessary or convenient, if the Company determines that additional time is necessary to permit further solicitation and vote of proxies in the event that there are insufficient votes to approve the Extension Proposal and/or the Redemption Limitation Amendment Proposal or if the Board determines before the Special Meeting that it is not necessary or no longer desirable to proceed with the other proposals.

Approval of the Extension Proposal and the Redemption Limitation Amendment Proposal requires the affirmative vote of the holders of at sixty five percent (65%) of the Class A Common Stock and Class B Common Stock, par value $0.0001 per share, of the Company issued to the Sponsor in a private placement prior to the IPO (“Class B Common Stock” and together with the Class A Common Stock, the “Common Stock”) issued and outstanding, voting together as a single class, represented in person or by proxy and entitled to vote thereon.

In connection with the Extension, public stockholders may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account established in connection with the IPO (the “Trust Account”), including interest earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable), divided by the number of then-issued and outstanding Class A Common Stock, regardless of how such public stockholders vote on the Extension Proposal, or if they vote at all. If the Extension is approved by the requisite vote of stockholders, the remaining public stockholders will retain their right to redeem their Class A Common Stock upon consummation of our initial business combination when it is submitted to a vote of the stockholders, subject to any limitations set forth in the Charter. In addition, public stockholders will be entitled to have their shares redeemed for cash if the Company has not completed an initial business combination by the Extended Date or the Additional Extension Date, as applicable.

Pursuant to the Charter, a public stockholder may request that the Company redeem all or a portion of such public stockholder’s public shares for cash if either of the Extension Proposal or the Redemption Limitation Amendment Proposal is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

(i)

(ii)

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, his or her own name, the holder must contact the transfer agent directly and instruct it to do so. Public stockholders may elect to redeem all or a portion of their public shares even if they vote for the Extension Proposal and/or the Redemption Limitation Amendment Proposal or do not vote at all at the Special Meeting.

If the Extension is not approved and we do not consummate an initial business combination by May 2, 2024, 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 subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

The Company’s sponsor is AltEnergy Acquisition Sponsor LLC, a Delaware limited liability company (the “Sponsor”). The Sponsor and the Company’s directors and officers have agreed to waive their respective rights to liquidating distributions from the Trust Account in respect of any Class B Common Stock or Private Placement Warrants (as defined below) held by it or them, as applicable, if the Company fails to complete an initial business combination by May 2, 2024, or by the applicable deadline as may be extended, although they will be entitled to liquidating distributions from the Trust Account with respect to any Class A Common Stock they hold if the Company fails to complete its initial business combination by such date. 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 May 2, 2024 or by the applicable deadline as may be extended.

If the Company liquidates, the Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party for services rendered or products sold to us, or a prospective target business with which we have entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the trust account to below the lesser of (i) $10.20 per public share and (ii) the actual amount per public share held in the trust account as of the date of the liquidation of the trust account, if less than $10.20 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the trust account (whether or not such waiver is enforceable) nor will it apply to any claims under our indemnity of the underwriters of this offering against certain liabilities, including liabilities under the Securities Act. The per-share liquidation price for the public shares is anticipated to be approximately $11.20 (based on the amount held in the Trust Account as of February 29, 2024 and estimated interest income and taxes post-February 29, 2024). Nevertheless, the Company cannot assure you that the per share distribution from the Trust Account, if the Company liquidates, will not be less than $11.20 due to unforeseen claims of potential creditors.

If the Extension Proposal is approved, such approval will constitute consent for the Company to (i) remove from the Trust Account an amount (the “Withdrawal Amount”) equal to the number of public shares properly redeemed multiplied by 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 the Company (less 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 funds remaining in the Trust Account after the removal of such Withdrawal Amount shall be available for use by the Company to complete an initial business combination on or before the Extended Date or the Additional Extension Date, as applicable. Holders of public shares who do not redeem their public shares now will retain their redemption rights and their ability to vote on an initial business combination through the Extended Date or the Additional Extension Date, as applicable, if the Extension Proposal is approved.

The withdrawal of the Withdrawal Amount will reduce the amount held in the Trust Account, and the amount remaining in the Trust Account may be significantly less than the $17,742,606.82 that was in the Trust Account as of February 29, 2024. In such an event, the Company may need to obtain additional funds to complete its initial business combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

Only stockholders of record of the Company as of the close of business on March 5, 2024, are entitled to notice of, and to vote at, the Special Meeting or any adjournment or postponement thereof. Each share of Common Stock entitles the holder thereof to one vote. On the record date, there were 7,327,478 shares of Common Stock issued and outstanding, including 7,077,478 shares of Class A Common Stock and 250,000 shares of Class B Common Stock. The Company’s warrants do not have voting rights in connection with the proposals.

Your vote is important. Proxy voting permits stockholders unable to attend the Special Meeting in person to vote their shares through a proxy. By appointing a proxy, your shares will be represented and voted in accordance with your instructions. You can vote your shares by completing and returning your proxy card or by completing the voting instruction form provided to you by your broker. Proxy cards that are signed and returned but do not include voting instructions will be voted by the proxy as recommended by the Board. You can change your voting instructions or revoke your proxy at any time prior to the Special Meeting by following the instructions included in this proxy statement and on the proxy card.

It is strongly recommended that you complete and return your proxy card before the Special Meeting date to ensure that your shares will be represented at the Special Meeting. You are urged to review carefully the information contained in the enclosed proxy statement prior to deciding how to vote your shares. If you have any questions or need assistance voting your Common Stock, please contact Jon Darnell by calling 203-299-1400 or by emailing info@altenergyacquisition.com.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL 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 any 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 our Board for use at the Special Meeting to be held virtually on April 16, 2024, or at any adjournments or postponement thereof. This proxy statement summarizes the information that you need to make an informed decision on the proposals to be considered at the Special Meeting.

AltEnergy is a blank check company incorporated on February 9, 2021 as a Delaware corporation for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (an “initial business combination”).

In March 2021, AltEnergy Acquisition Sponsor LLC (the “Sponsor”) purchased an aggregate of 5,750,000 shares of Class B Common Stock, par value $0.0001, of the Company (“Class B Common Stock”), for an aggregate purchase price of $25,000, or approximately $0.004 per share.

On November 2, 2021, the Company consummated its initial public offering (“IPO”) of 23,000,000 units at $10.00 per unit. Each unit consists of one Class A share of Common Stock, par value $0.0001 per share, of the Company (“Class A Common Stock” or “public shares”) and one-half of one redeemable warrant to purchase one share of Class A Common Stock at an exercise price of $11.50 per share, subject to adjustment. Simultaneously with the consummation of the IPO, AltEnergy completed the private placement of an aggregate of 10,800,000 warrants (the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant, to the Sponsor and B. Riley Principal Investments, LLC, an affiliate of B. Riley Securities, Inc., generating total gross proceeds of $10,800,000. Following the closing of the IPO, a total of $234,600,000 ($10.00 per unit) of the net proceeds from its IPO and the sale of the Private Placement Warrants were placed in a trust account (the “Trust Account”) with Continental Stock Transfer & Trust Company (“Continental”) acting as trustee. Our Charter provides for the return of the IPO proceeds held in the Trust Account to the holders of public shares if we do not complete our initial business combination by May 2, 2024.

On April 26, 2023 and April 27, 2024, the Company and the Sponsor entered into non-redemption agreements (the “Non-Redemption Agreements”) with certain unaffiliated third parties (each, a “Holder”). Pursuant to the Non-Redemption Agreements, such Holders agreed for the benefit of the Company to (i) vote such investors’ Class A Common Stock owned or acquired in favor of the proposal to amend the Company’s Amended and Restated Certificate of Incorporation to extend the time the Company is permitted to close an initial business combination and (ii) not redeem their Class A Common Stock in connection with such stockholder vote to amend the Company’s Amended and Restated Certificate of Incorporation. In connection with these commitments from the Holders, immediately prior to, and substantially concurrently with, the closing of an initial business combination, (i) the Sponsor (or its designees) will surrender and forfeit to the Company for no consideration an aggregate of 250,000 shares of the Company’s Class B common stock, par value $0.0001 per share, held by the Sponsor (the “Forfeited Shares”) and (ii) the Company shall issue to the Holders a number of shares of Class A Common Stock equal to the Forfeited Shares.

On April 28, 2023, the Company held special meeting at which its stockholders approved the proposal to file an amendment to the Company’s Amended and Restated Certificate of Incorporation with the Secretary of State of Delaware to extend the date by which the Company must (1) consummate its initial business combination, (2) cease its operations except for the purpose of winding up if it fails to complete such initial business combination, and (3) redeem all of the shares of Class A Common Stock included as part of the units sold in the IPO, from May 2, 2023 to May 2, 2024 (the “First Extension”). In connection with the First Extension, stockholders elected to redeem an aggregate of 21,422,522 shares of Class A Common Stock. As a result, an aggregate of $222,365,779 (or approximately $10.38 per share) was released from the Trust Account to pay such stockholders. The Charter (as defined below) provides for the return of the IPO proceeds held in the Trust Account to the holders of public shares (as defined below) if the Company does not complete its initial business combination by May 2, 2024, unless otherwise extended.

Also on April 28, 2023, the Sponsor elected to convert on a one-for-one basis 5,500,000 shares of Class B Common Stock held directly by the Sponsor into an aggregate of 5,500,000 shares of Class A Common Stock.

On February 21, 2024, the Company entered into an Agreement and Plan of Merger (as may be further amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among the Company, Car Tech Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“Merger Sub”), and Car Tech, LLC, an Alabama limited liability company (“Car Tech”), pursuant to which Merger Sub will merge with and into Car Tech, with Car Tech as the surviving corporation and a wholly owned subsidiary of the Company (the “Merger”). The Merger and the other transactions contemplated by the Merger Agreement are collectively referred to herein as the “Business Combination.”

While the Company and the other parties to the Merger Agreement are working toward satisfaction of the conditions to completion of the Business Combination, the Board has determined that there may not be sufficient time before May 2, 2024 to complete the Business Combination. Therefore, the Board has determined that it is in the best interests of the Company’s stockholders to extend the date by which the Company has to complete an initial business combination to the Extended Date or up to the Additional Extension Date (each as defined below).

Additionally, the Company believes that the Redemption Limitation (as defined below) is no longer needed. The purpose of such limitation was initially to ensure that the Company did not become subject to the SEC’s “penny stock” rules. Because the public shares would not be deemed to be “penny stock” as such securities are listed on a national securities exchange, the Company is presenting the Redemption Limitation Amendment Proposal (as defined below) to facilitate the consummation of the Business Combination.

What is being voted on?

You are being asked to vote on the following proposals:

a proposal to amend the Company’s Amended and Restated Certificate of Incorporation (the “Charter”) in the form of the proposed amendment to the Charter set forth in Annex A of the accompanying proxy statement to extend the date by which the Company must (1) consummate an initial business combination or (2) cease its operations except for the purpose of winding up if it fails to complete such initial business combination, and redeem all of the Class A Common Stock included as part of the units sold in the IPO, from May 2, 2024 to November 2, 2025 (the “Extended Date”) and to allow the Board, without another stockholder vote, to elect to further extend the date to consummate an initial business combination after the Extended Date up to six times, by an additional month each time, upon two days’ advance notice prior to the applicable deadline, up to May 2, 2025 (the “Additional Extension Date” and together with the Extended Date the “Extension” and such proposal, the “Extension Proposal”);

a proposal to amend the Charter pursuant to an amendment to the Charter in the form set forth in Annex A of this proxy statement (the “Redemption Limitation Amendment” and such proposal, the “Redemption Limitation Amendment Proposal”) to eliminate from the Charter the limitation that the Company shall not redeem Class A Common Stock included as part of the units sold in the IPO (including any shares issued in exchange thereof, the “public shares”) to the extent that such redemption would cause the Company’s net tangible assets to be less than $5,000,001 following such redemptions (the “Redemption Limitation”). The Redemption Limitation Amendment would allow the Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation;

a proposal to approve the adjournment of the Special Meeting to a later date or dates, if necessary or convenient, 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 Extension Proposal (the “Adjournment Proposal”), which will only be presented at the Special Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Special Meeting to approve the Extension Proposal and/or the Redemption Limitation Amendment Proposal, in which case the Adjournment Proposal will be the only proposal presented at the Special Meeting.

You are not being asked to vote on an initial business combination, including 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 our initial business combination if and when it is submitted to stockholders and the right to redeem your public shares for cash in the event an initial business combination is approved and completed or the Company has not consummated an initial business combination by the Extended Date or the Additional Extension Date, as applicable.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our Board. Russell Stidolph and Andrea Dobi have each been designated as proxy by our Board. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Special Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our Board as described below. If any matters not described in this proxy statement are properly presented at the Special Meeting, the proxy holders will use their own judgment to determine how to vote the shares. If the Special Meeting is adjourned, the proxy holders can vote the shares on the new Special Meeting date as well, unless you have properly revoked your proxy instructions, as described elsewhere herein.

Can I attend the Special Meeting?

The Special Meeting will be held at 10:00AM, Eastern Time, on April 2, 2024. The Special Meeting will be a completely virtual meeting of stockholders, which will be conducted via live webcast. You will be able to attend the Special Meeting online, vote and submit your questions during the Special Meeting by visiting https://www.cstproxy.com/altenergyacquisition/2024. The Special Meeting will comply with the meeting rules of conduct. The rules of conduct will be posted on the virtual meeting web portal. We encourage you to access the Special Meeting webcast prior to the start time. Online check-in will begin fifteen minutes prior to the start time of the Special Meeting, and you should allow ample time for the check-in procedures. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage-paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares.

Why should I vote to approve the Extension?

Our Board believes stockholders will benefit from the Company consummating an initial business combination and is proposing the Extension to extend the date by which the Company has to complete an initial business combination until the Extended Date or the Additional Extension Date, as applicable. The Extension would give the Company the opportunity to complete its initial business combination.

The Charter currently provides that if the Company does not complete an initial business combination by May 2, 2024, 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 subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining public stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the Delaware General Corporation Law (the “DGCL”) to provide for claims of creditors and other requirements of applicable law.

We believe that the provisions of the Charter described in the preceding paragraph were included to protect the Company’s stockholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable initial business combination in the timeframe contemplated by the Charter. We also believe, however, that given the Company’s expenditure of time, effort and money on pursuing an initial business combination and our belief that an initial business combination offers an attractive investment for our stockholders, the Extension is warranted.

In connection with the Extension, public stockholders may elect to redeem their shares for 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 the Company (less taxes payable), divided by the number of then-issued and outstanding Class A Common Stock, regardless of how such public stockholders vote on the Extension Proposal, or if they vote at all.

Liquidation of the Trust Account is a fundamental obligation of the Company to the public stockholders and the Company is not proposing and will not propose to change that obligation to the public stockholders. If holders of public shares do not elect to redeem their public shares, such holders shall retain redemption rights in connection with an initial business combination. Assuming the Extension is approved, the Company will have until the Extended Date to complete an initial business combination, unless the Company obtains any additional extension.

Our Board recommends that you vote in favor of the Extension Proposal, but expresses no opinion as to whether you should redeem your public shares.

Why should I vote to approve the Redemption Limitation Amendment Proposal?

As discussed above, the Board believes the opportunity to consummate an initial business combination is in the best interests of the Company and its stockholders. In connection with the Extension, public stockholders may elect 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, including interest earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable), divided by the number of then-issued and outstanding shares of Class A Common Stock, regardless of how such public stockholders vote on the Extension Proposal, or if they vote at all. Unless the Redemption Limitation Amendment Proposal is approved, the Company will not proceed with the Extension if redemptions of the Company’s public shares would cause the Company to exceed the Redemption Limitation. By eliminating the Redemption Limitation, the Company makes it more likely that it will proceed with the Extension and have the opportunity to consummate the Business Combination.

If holders of public shares do not elect to redeem their public shares, such holders will retain redemption rights in connection with any future initial business combination the Company may propose. Assuming the Extension Proposal is approved, the Company will have until November 2, 2024 to consummate an initial business combination (without giving effect to the Board’s option, without another stockholder vote, to elect to further extend the date to consummate an initial business combination after November 2, 2024 up to six times, by an additional month each time, upon two days’ advance notice prior to the applicable deadline, up to May 2, 2025).

How do the Company insiders intend to vote their shares?

The Sponsor, the Company’s directors, officers and initial stockholders and their permitted transferees (collectively, the “Initial Stockholders”) are expected to vote any Class A Common Stock and Class B Common Stock (together, the “Common Stock”) over which they have voting control in favor of the Extension Proposal, the Redemption Limitation Amendment Proposal and, if presented, the Adjournment Proposal.

The Initial Stockholders are not entitled to redeem any Common Stock held by them. On the record date, the Initial Stockholders beneficially owned and were entitled to vote 5,750,000 shares of Common Stock, which represents % of the Company’s issued and outstanding Common Stock.

Subject to applicable securities laws (including with respect to material nonpublic information), the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates may (i) purchase public shares from institutional and other investors (including those who vote, or indicate an intention to vote, against any of the proposals presented at the Special Meeting, or elect to redeem, or indicate an intention to redeem,

public shares), (ii) enter into transactions with such investors and others to provide them with incentives to not redeem their public shares, or (iii) execute agreements to purchase such public shares from such investors or enter into non-redemption agreements in the future. In the event that the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates purchase public shares in situations in which the tender offer rules restrictions on purchases would apply, they (a) would purchase the public shares at a price no higher than the price offered through the Company’s redemption process (i.e., approximately $11.20 per share, based on the amounts held in the Trust Account as of February 29, 2024); (b) would represent in writing that such public shares will not be voted in favor of approving the Extension; and (c) would waive in writing any redemption rights with respect to the public shares so purchased.

To the extent any such purchases by the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates are made in situations in which the tender offer rules restrictions on purchases apply, the Company will disclose in a Current Report on Form 8-K prior to the Special Meeting the following: (i) the number of public shares purchased outside of the redemption offer, along with the purchase price(s) for such public shares; (ii) the purpose of any such purchases; (iii) the impact, if any, of the purchases on the likelihood that the Extension will be approved; (iv) the identities of the securityholders who sold to the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates (if not purchased on the open market) or the nature of the securityholders (e.g., 5% security holders) who sold such public shares; and (v) the number of Common Stock for which the Company has received redemption requests pursuant to its redemption offer.

The purpose of such share purchases and other transactions would be to increase the likelihood of otherwise limiting the number of public shares electing to redeem.

If such transactions are effected, the consequence could be to cause the Extension to be effectuated in circumstances where such effectuation could not otherwise occur. Consistent with SEC guidance, purchases of shares by the persons described above would not be permitted to be voted for the Extension at the Special Meeting and could decrease the chances that the Extension would be approved. In addition, if such purchases are made, the public “float” of our securities and the number of beneficial holders of our securities may be reduced, possibly making it difficult to maintain or obtain the quotation, listing or trading of our securities on a national securities exchange.

The Company hereby represents that any Company securities purchased by the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates in situations in which the tender offer rules restrictions on purchases would apply would not be voted in favor of approving the Extension Proposal.

Who is the Company’s Sponsor?

The Company’s Sponsor is AltEnergy Acquisition Sponsor LLC, a Delaware limited liability company. The Sponsor currently owns an aggregate of 5,500,000 shares of Class A Common Stock, 250,000 shares of Class B Common Stock and 10,400,000 Private Placement Warrants. Russell Stidolph, the Company’s Chief Executive Officer and a member of the Board, is the manager of the Sponsor.

What vote is required to approve the Extension Proposal and the Redemption Limitation Amendment Proposal?

The approval of the Extension Proposal and the Redemption Limitation Amendment Proposal will require the affirmative vote of holders of at least 65% of our outstanding shares of Common Stock on the record date.

What vote is required to approve the Adjournment Proposal?

Approval of the Adjournment Proposal will require the affirmative vote of a majority of the Common Stock issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Special Meeting.

Is the Company subject to the Investment Company Act of 1940?

The Company completed its IPO on November 2, 2021. As a blank check company, the efforts of the Company’s board of directors and management have been focused on pursuing its initial business combination. As of the date hereof, the Company has entered into the Merger Agreement with Car Tech and focused on consummating the Business Combination.

On January 24, 2024, the SEC adopted the final rules (the “SPAC Final Rules”), relating to, among the other things, the extent to which special purpose acquisition companies (“SPACs”) could become subject to regulation under the Investment Company Act of 1940 (the “Investment Company Act”). The SPAC Final Rules provide that whether a SPAC is an “investment company” under Section 3(a)(1)(A) of the subject to the Investment Company Act is based on particular facts and circumstances. A specific duration period of a SPAC is not the sole determinant, but one of the long-standing factors to consider in determination of a SPAC’s status under the Investment Company Act. A SPAC could be deemed as an investment company at any stage of its operation. The determination of a SPAC’s status as an investment company includes analysis of a SPAC’s activities, depending upon the facts and circumstances, including but not limited to, the nature of SPAC assets and income, the activities of a SPAC’s officers, directors and employees, the duration of a SPAC, the manner a SPAC holding itself out to investors, and the merging with an investment company. The SPAC Final Rules were published in the Federal Register on February 26, 2024, and will become effective on July 1, 2024 (125 days after publication in the Federal Register).

There is currently uncertainty concerning the applicability of the Investment Company Act to a SPAC, including a company like ours, that has not completed its initial business combination within 24 months of the effective date of the IPO Registration Statement. It is possible that a claim could be made that we have been operating as an unregistered investment company. If we were deemed to be an investment company for purposes of the Investment Company Act, we might be forced to abandon our efforts to complete an initial business combination and instead be required to liquidate the Company. If we are required to liquidate the Company, our investors would not be able to realize the benefits of owning stock in a successor operating business, including the potential appreciation in the value of our stock and warrants following such a transaction, and our warrants would expire worthless.

What if I want to vote against or don’t want to vote for any of the proposals?

If you do not want any of the proposals to be approved, you must abstain, not vote or vote against such proposal. A stockholder’s failure to vote by proxy or to vote in person at the Special Meeting will not be counted towards the number of Common Stock required to validly establish a quorum. Abstentions will be counted in connection with the determination of whether a valid quorum is established.

Will you seek any further extensions to liquidate the Trust Account?

Other than the extension until the Extended Date and up until the Additional Extension Date, if applicable, as described in this proxy statement, we do not anticipate seeking any further extension to consummate an initial business combination.

What happens if the Extension Proposal is not approved?

and 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 the remaining public stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

The Initial Stockholders have agreed to waive their respective rights to liquidating distributions from the Trust Account in respect of any Class B Common Stock held by it or them, as applicable, if the Company fails to complete an initial business combination by May 2, 2024, or by the applicable deadline as may be extended, although they will be entitled to liquidating distributions from the Trust Account with respect to any Class A Common Stock they hold if the Company fails to complete its initial business combination by such date. 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 May 2, 2024 or by the applicable deadline as may be extended. The Company will pay the costs of liquidation from its remaining assets outside of the Trust Account.

What happens if the Redemption Limitation Amendment Proposal is not approved?

If the Extension Proposal is approved but the Redemption Limitation Amendment Proposal is not approved, the Company will not redeem public shares in an amount that would exceed the Redemption Limitation. In the event that the Redemption Limitation Amendment Proposal is not approved and the Company receives notice of redemptions of public shares approaching or in excess of the Redemption Limitation, the Company and/or the Sponsor may take action to increase the Company’s net tangible assets to avoid exceeding the Redemption Limitation. If the Redemption Limitation Amendment Proposal is not approved and the Redemption Limitation is exceeded, either because the Company does not take action to increase its net tangible assets or because its attempt to do so is not successful, then the Company will not proceed with the Extension and the Company will not redeem any public shares in connection with the Extension Proposal, and the public stockholders will retain their shares and redemption rights.

If the Extension is approved, what happens next?

The Company is continuing its efforts to complete its initial business combination, which will involve completing the closing conditions to the Merger Agreement, including, without limitation, any filings required pursuant to antitrust laws, and the expiration of the required waiting periods thereunder, the Registration Statement becoming effective and holding an extraordinary general meeting to consider and approve the Business Combination and related proposals.

The Company is seeking approval of the Extension Proposal because the Company may not be able to complete all of the tasks listed above, and others that may be required to consummate the Business Combination, prior to May 2, 2024. If the Extension Proposal is approved, the Company expects to continue to work to complete the closing conditions to the Merger Agreement and to seek stockholder approval of the Business Combination and related proposals. If stockholders approve the Business Combination and any other proposals required to consummate the Business Combination, the Company expects to consummate the Business Combination as soon as possible following such stockholder approval and satisfaction of the other conditions to the consummation of the Business Combination.

Upon approval of the Extension Proposal by the holders of at least sixty five percent (65%) of the Common Stock represented in person or by proxy and entitled to vote thereon and who do so at the Special Meeting, the Company will file an amendment to the Charter with the Secretary of State of the State of Delaware (the “Delaware Secretary”) in the form attached as Annex A hereto. The Company will remain a reporting company under the Exchange Act, and its units, Class A Common Stock and public warrants will remain publicly traded.

If the Extension is approved, any removal of any Withdrawal Amount (defined as an amount equal to the number of public shares properly redeemed multiplied by 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 the Company (less taxes payable), divided by the number of then outstanding public shares) from the Trust Account will reduce the amount remaining in the Trust Account and increase the percentage interest of Common Stock held by the Sponsor through the Class B Common Stock.

If the Extension is approved, an affiliate of the Sponsor will continue to accrue payments from the Company of $15,000 per month for office space and secretarial and administrative services provided to members of our management team pursuant to the Administrative Services Agreement, dated as of October 28, 2021 and amended as of January 28, 2023, by and between the Company and the Sponsor. The accrued amounts shall be payable on the consummation of a business combination or the Company’s liquidation.

Where will I be able to find the voting results of the Special Meeting?

We will announce preliminary voting results at the Special Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Special Meeting. If final voting results are not available to us in time to file a Current Report on Form 8-K within four business days after the Special Meeting, we will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to such Current Report on Form 8-K as soon as they become available.

Would I still be able to exercise my redemption rights in connection with a vote to approve a proposed initial business combination?

Yes. Assuming you are a stockholder as of the record date for voting on a proposed initial business combination, such as the Business Combination, you will be able to vote on a proposed initial business combination if and when it is submitted to stockholders. If you disagree with an initial business combination, such as the Business Combination, you will retain your right to redeem your public shares upon consummation of such initial business combination, subject to any limitations set forth in our Charter.

How do I change my vote?

Stockholders may send a later-dated, signed proxy card to the Company at 600 Lexington Avenue, 9th Floor, New York, New York 10022, attn.: Corporate Secretary, so that it is received prior to the vote at the Special Meeting (which is scheduled to take place on April 16, 2024). Stockholders also may revoke their proxy by sending a notice of revocation to the Company’s Corporate Secretary, which must be received prior to the vote at the Special Meeting, or by attending the Special Meeting, revoking their proxy and voting in person. However, if your shares are held in “street name” by your broker, bank or another nominee, you must contact your broker, bank or other nominee to change your vote.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count “FOR” and “AGAINST” votes, abstentions and broker non-votes for each of the proposals. A stockholder’s failure to vote by proxy or to vote in person at the meeting will not be counted towards the number of Common Stock required to validly establish a quorum. Abstentions will be counted in connection with the determination of whether a valid quorum is established.

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

If you do not give instructions to your broker, your broker can vote your shares with respect to “discretionary” items, but not with respect to “non-discretionary” items. We believe that each of the proposals are “non-discretionary” items.

Your broker can vote your shares with respect to “non-discretionary” items only if you provide instructions on how to vote. You should instruct your broker to vote your shares. Your broker can tell you how to provide these instructions. If you do not give your broker instructions, your shares will be treated as broker non-votes with respect to all proposals. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Special Meeting.

What is a quorum?

A quorum is the minimum number of shares required to be present at the Special Meeting to be properly held under our Charter and the DGCL. The presence, in person, by proxy, or if a corporation or other non-natural person, by its duly authorized representative or proxy, of the holders of a majority of the issued and outstanding Common Stock entitled to vote at the Special Meeting constitutes a quorum. Proxies that are marked “abstain” and proxies relating to “street name” shares that are returned to us but marked by brokers as “not voted” (so-called “broker non-votes”) will be treated as shares present for purposes of determining the presence of a quorum on all matters. If a stockholder does not give the broker voting instructions, under applicable self- regulatory organization rules, its broker may not vote its shares on “non-discretionary” matters. We believe that each of the proposals is a “nondiscretionary” matter.

Who can vote at the Special Meeting?

Holders of our Common Stock as of the close of business on March 5, 2024, the record date, are entitled to vote at the Special Meeting. As of the record date, there were 7,327,478 shares of Common Stock issued and outstanding, including 7,077,478 shares of Class A Common Stock and 250,000 shares of Class B Common Stock. The Company’s warrants do not have voting rights in connection with the proposals. In deciding all matters at the Special Meeting, each stockholder will be entitled to one vote for each share held by them on the record date. Holders of Class A Common Stock and holders of Class B Common Stock will vote together as a single class on all matters submitted to a vote of our stockholders except as required by law. The Sponsor owns 5,500,000 shares of Class A Common Stock and 250,000 shares of Class B Common Stock, constituting approximately 78.5% of our issued and outstanding Common Stock.

Registered Stockholders. If our shares are registered directly in your name with our transfer agent, Continental, you are considered the stockholder of record with respect to those shares. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote in person at the Special Meeting.

Street Name Stockholders. If our shares are held on your behalf in a brokerage account or by a bank or other nominee, you are considered the beneficial owner of those shares held in “street name,” and your broker or nominee is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker or nominee as to how to vote your shares. However, since a beneficial owner is not the stockholder of record, you may not vote your Common Stock at the Special Meeting unless you follow your broker’s procedures for obtaining a legal proxy. Throughout this proxy, we refer to stockholders who hold their shares through a broker, bank or other nominee as “street name stockholders.”

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

Yes. After careful consideration of the terms and conditions of these proposals, the Board has determined that each of the proposals are in the best interests of the Company and its stockholders. The Board recommends that the Company’s stockholders vote “FOR” each of the proposals.

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

The Sponsor and the Company’s 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 Class B Common Stock, Private Placement Warrants that may become exercisable in the future and the possibility of future compensatory arrangements. See the section entitled “Proposal No. 1—The Extension Proposal—Interests of the Sponsor and the Company’s Directors and Officers.”

Are there any dissenter’s or appraisal or similar rights for dissenting stockholders?

Neither the DGCL nor our Charter provide for appraisal or other similar rights for dissenting stockholders in connection with any of the proposals to be voted upon at the Special Meeting. Accordingly, our stockholders will have no right to dissent and obtain payment for their shares.

What happens to the Company’s warrants if the Extension is not approved?

If the Extension is not approved and we do not consummate an initial business combination by May 2, 2024, 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 subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining public stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of 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 May 2, 2024 or by the applicable deadline as may be extended.

What happens to the Company’s warrants if the Extension is approved?

If the Extension and the Redemption Limitation Amendment Proposal are approved, the Company will continue to attempt to consummate an initial business combination until the Extended Date and up until the Additional Extension Date, as applicable, and will retain the blank check company restrictions previously applicable to it. The warrants will remain outstanding in accordance with their terms.

How are the funds in the Trust Account currently being held?

The funds in the Trust Account have, since our IPO, 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 have been operating as an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act), we may, and likely will, on or prior to the 24-month anniversary of the effective date of the registration statement filed in connection with our IPO (the “IPO Registration Statement”), should our Company continue to exist to such date, instruct 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 and thereafter to hold all funds in the Trust Account in cash until the earlier of consummation of our initial business combination or liquidation. As a result, following such liquidation, we will likely receive minimal interest, if any, on the funds held in the Trust Account, which would reduce the dollar amount our public stockholders would receive upon any redemption or liquidation of the Company.

How do I vote?

If you were a holder of record of Common Stock on March 5, 2024, the record date for the Special Meeting, you may vote by virtual attendance at the Special Meeting or by submitting a proxy for the Special Meeting. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage-paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the Special Meeting virtually, obtain a valid proxy from your broker, bank or nominee.

How do I redeem my Common Stock?

Pursuant to the Charter, a public stockholder may request that the Company redeem all or a portion of such public stockholder’s public shares for cash if the Extension Proposal or the Redemption Limitation Amendment Proposal is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

(i)

(ii)

prior to 5:00 p.m., Eastern Time, on April 11, 2024 (two business days prior to the vote at the Special Meeting), (a) submit a written request to Continental, the Company’s transfer agent, that the Company redeem your public shares for cash and (b) deliver your public shares to the transfer agent, physically or electronically through The Depository Trust Company.

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the transfer agent directly and instruct it to do so. Public stockholders may elect to redeem all or a portion of their public shares even if they vote for the Extension Proposal.

Based upon the amount held in the Trust Account as of February 29, 2024, which was $17,742,606.82 and estimated interest income and taxes post-February 29, 2024, the Company estimates that the per-share price at which public shares may be redeemed from cash held in the Trust Account will be approximately $11.20 at the time of the Special Meeting. The closing price of a share of Class A Common Stock on March 22, 2024, was $11.25. The Company cannot assure stockholders that they will be able to sell their 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.

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.

RISK FACTORS

You should consider carefully all of the risks described in our Annual Report on Form 10-K filed with the SEC on April 11, 2023, and in the 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 will enable us to complete an initial business combination

Approving the Extension involves a number of risks. Even if the Extension is approved, the Company can provide no assurances that an initial business combination will be consummated prior to the Extended Date or the Additional Extension Date, as applicable. Our ability to consummate any business combination is dependent on a variety of factors, many of which are beyond our control. We are required to offer stockholders the opportunity to redeem shares in connection with the Extension and the Redemption Limitation Amendment Proposal, and we will be required to offer stockholders redemption rights again in connection with any stockholder vote to approve our initial business combination. Even if the Extension and/or our initial business combination are approved by our stockholders, it is possible that redemptions will leave us with insufficient cash to consummate such initial business combination on commercially acceptable terms, or at all. The fact that we will have separate redemption periods in connection with the Extension and our initial 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 the Extension Proposal is not approved, the Company will be required to cease all operations on May 2, 2024, except for the purposes of winding up, and would redeem its public shares and liquidate, in which case the Company’s public stockholders may receive only $11.20 per share, or less than such amount in certain circumstances, and will forgo any of the potential benefits from a completed initial business combination, including potential share price appreciation and the ability to exercise the Company’s warrants.

If the Extension Proposal is not approved, the Company will (i) cease all operations on May 2, 2024, except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining public stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the Delaware General Corporation Law to provide for claims of creditors and other requirements of applicable law. In such case, the public stockholders may receive only $11.20 per share on the redemption of their shares (based on the amount held in the Trust Account as of February 29, 2024 and assuming the Extension Proposal is not approved). Additionally, if the Extension Proposal is not approved, you will forgo any of the potential benefits that could have been realized from a completed initial business combination resulting in owning shares in a successor operating business, including the potential appreciation in the value of the Company’s public shares and warrants following such a transaction, and the Company’s warrants would expire worthless. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants.

In the event the Extension Proposal and/or the Redemption Limitation Amendment Proposal is approved and the Company amends the Charter, Nasdaq may delist the Company’s securities from trading on its exchange following stockholder redemptions in connection with such amendment, which could limit investors’ ability to make transactions in the Company’s securities and subject the Company to additional trading restrictions.

The Company’s Class A Common Stock, public warrants and units are listed on the Nasdaq Global Market. The Company is subject to compliance with Nasdaq’s continued listing requirements in order to maintain the listing of its securities on Nasdaq. Such continued listing requirements for the Class A Common Stock include:

•

maintaining a market value of at least $50,000,000 attributable to the Class A Common Stock and a market value of publicly-held Class A Common Stock of at least $15,000,000, excluding Class A Common Stock held by the Company’s directors, officers, or their immediate families and other concentrated holdings of ten percent or greater, in each case measured over thirty consecutive trading days;

•

400 public stockholders; and

•

1,100,000 publicly-held shares of Class A Common Stock.

On October 9, 2023, the Company received a written notice (the “Notice”) from the Nasdaq Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) indicating that the Company was not in compliance with Nasdaq Listing Rule 5450(a)(2), which requires the Company to maintain at least 400 total holders for continued listing on the Nasdaq Global Market (the “Minimum Total Holders Rule”). The Company submitted a plan to regain compliance with the Minimum Total Holders Rule and request an extension of up to 180 calendar days from the date of the Notice to evidence compliance with the Minimum Total Holders Rule. If Nasdaq does not accept the Company’s plan, the Company will have the opportunity to appeal the decision in front of a Nasdaq Hearings Panel.

The Company expects that if it is unable to regain compliance with the Minimum Total Holders Rule, or if its shares of Class A Common Stock fail to meet Nasdaq’s continued listing requirements, the Company’s units will also fail to meet Nasdaq’s continued listing requirements for those securities. The Company cannot assure you that it will be able to regain compliance with the Minimum Total Holders Rule or that any of its Class A Common Stock or units will be able to meet any of Nasdaq’s continued listing requirements following any stockholder redemptions of its public shares in connection with the amendment of the Charter pursuant to the Extension Proposal and/or the Redemption Limitation Amendment Proposal. If the Company’s securities do not meet Nasdaq’s continued listing requirements, Nasdaq may delist the Company’s securities from trading on its exchange. If Nasdaq delists any of the Company’s securities from trading on its exchange and the Company is not able to list such securities on another national securities exchange, the Company expects such securities could be quoted on an over-the-counter market. If this were to occur, the Company could face significant material adverse consequences, including:

•

a limited availability of market quotations for the Company’s securities;

•

reduced liquidity for the Company’s securities;

•

a determination that the Class A Common Stock is a “penny stock” which will require brokers trading in Class A Common Stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for the Company’s securities;

•

a limited amount of news and analyst coverage; and

•

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

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” The Company’s Class A Common Stock and units qualify as covered securities under such statute. Although the

states are preempted from regulating the sale of covered securities, the federal statute does allow the states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. While the Company is not aware of a state having used these powers to prohibit or restrict the sale of securities issued by SPACs, certain state securities regulators view blank check companies unfavorably and might use these powers, or threaten to use these powers, to hinder the sale of securities of blank check companies in their states. Further, if the Company was no longer listed on Nasdaq, the Company’s securities would not qualify as covered securities under such statute and the Company would be subject to regulation in each state in which it offers its securities.

The Extension Proposal will give the Board the authority to extend the date by which the Company must consummate an initial business combination or cease its operations except for the purpose of winding up if it fails to complete such initial business combination, and redeem all of the Class A Common Stock included as part of the units sold in the Company’s IPO (the “Termination Date”), from May 2, 2024, to November 2, 2024 and to allow the Board to further extend the date to consummate an initial business combination up to May 2, 2025, which is a date that is in violation of applicable listing standards of the Nasdaq.

If the Extension Proposal passes, the Board may elect to extend the Termination Date beyond November 2, 2024, and if we have not completed an initial business combination by November 2, 2024, we will be in violation of Nasdaq listing standards.

Section IM-5101-2(b) of the Nasdaq Listing Rules requires that any special purpose acquisition company, such as the Company, must within 36 months of the effectiveness of its registration statement in connection with its initial public offering, or such shorter period that the Company specifies in its registration statement, must complete one or more target business combinations having an aggregate fair market value of at least 80% of the value of the trust account (excluding any deferred underwriters’ fees and taxes payable on the income earned on the trust account) at the time of the agreement to enter into the initial business combination. The date that is 36 months following the effectiveness of our registration statement is November 2, 2024. If the Extension Proposal is approved, our Board will have the authority to extend the Termination Date beyond November 2, 2024 up to six times, in one-month increments (though the Board may decline to exercise this authority). If the Board elects to extend the Termination Date each time that it is able to do so pursuant to the Extension Proposal, the latest possible termination date authorized by the Extension Proposal would be May 2, 2025.

Any violation of Nasdaq Listing Rules would likely result in the suspension or delisting of our securities from Nasdaq, which would have a material adverse effect on the Company’s business, including the material adverse consequences described in the above risk factor relating to the potential delisting of our securities in connection with a failure of the Company to regain compliance with the Minimum Total Holders Rule or otherwise comply with Nasdaq’s continued listing requirements. Additionally, any such delisting would materially and adversely impact our ability to complete a business combination transaction, and would likely cause us to enter liquidation.

The Board may decline to exercise a one-month extension that would otherwise be permitted under the Extension Proposal if doing so would cause us to be in violation of applicable listing standards of the Nasdaq. There can be no assurance that Nasdaq will change its listing standards, or forebear from enforcing them against us. Accordingly, even if the Extension Proposal is approved, our Board may voluntarily elect not to extend the termination date beyond November 2, 2024 in order to avoid possible suspension or delisting.

There are no assurances that the approval of the Extension Proposal will enable us to complete a business combination.

Approving the Extension Proposal involves a number of risks. Even if the Extension Proposal is approved, the Company can provide no assurances that an initial business combination will be consummated prior to May 2, 2025. Our ability to consummate any business combination is dependent on a variety of factors, many of

which are beyond our control. If the Extension Proposal is approved, the Company expects to seek stockholder approval of a business combination. We are required to offer stockholders the opportunity to redeem public shares in connection with the Extension Proposal, and we will be required to offer stockholders redemption rights again in connection with any stockholder vote to approve a business combination. Even if the Extension Proposal and/or any business combination are approved by our stockholders, it is possible that redemptions will leave us with insufficient cash to consummate a business combination on commercially acceptable terms, or at all. The fact that we will have separate redemption periods in connection with the Extension Proposal and a 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 public shares on the open market. The price of our public shares may be volatile, and there can be no assurance that stockholders will be able to dispose of our public 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 and, as a result, we may abandon our efforts to consummate the Business Combination (or another initial business combination) and liquidate the Company

As described further above, the SPAC Final Rules relate, among other matters, to the circumstances in which SPACs such as the Company could potentially be subject to the Investment Company Act and the regulations thereunder. The SPAC Final Rules provide that whether a SPAC is an “investment company” under Section 3(a)(1)(A) of the subject to the Investment Company Act is based on particular facts and circumstances. A specific duration period of a SPAC is not the sole determinant, but one of the long-standing factors to consider in determination of a SPAC’s status under the Investment Company Act. A SPAC could be deemed as an investment company at any stage of its operation. The determination of a SPAC’s status as an investment company includes analysis of a SPAC’s activities, depending upon the facts and circumstances, including but not limited to, the nature of SPAC assets and income, the activities of a SPAC’s officers, directors and employees, the duration of a SPAC, the manner a SPAC holding itself out to investors, and the merging with an investment company. The SPAC Final Rules were published in the Federal Register on February 26, 2024, and will become effective on July 1, 2024 (125 days after publication in the Federal Register).

The Company is currently assessing the relevant risks of being deemed to have been operating as an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act). The longer that the funds in the Trust Account are held in short-term U.S. government treasury obligations or in money market funds invested exclusively in such securities, there is a greater risk that the Company may be considered an unregistered investment company. 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, our activities would be severely restricted. In addition, we would be subject to additional burdensome regulatory requirements and expenses for which we have not allotted funds. As a result, if we are deemed an investment company under the Investment Company Act, we may abandon our efforts to consummate an initial business combination and instead liquidate the Company.

A new 1% U.S. federal excise tax could be imposed on us in connection with redemptions by us of our shares

On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax on certain repurchases (including redemptions) of stock by publicly traded domestic (i.e., U.S.) corporations and certain domestic subsidiaries of publicly traded foreign corporations after December 31, 2022. The excise tax is imposed on the repurchasing corporation itself, not on its stockholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In

addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax. On December 27, 2022, the Internal Revenue Service issued a notice of its intention to issue proposed regulations providing additional guidance with respect to the excise tax. The notice states that the excise tax does not apply to repurchases that occur in the taxable year in which the publicly traded corporation liquidates and dissolves.

Any redemption or other repurchase of our shares that occurs after December 31, 2022 in connection with an initial business combination, the Extension Proposal and/or the Redemption Limitation Amendment Proposal, or otherwise may be subject to the excise tax. Whether and to what extent we would be subject to the excise tax in connection with the Extension and an initial business combination would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the initial business combination, Extension Proposal and/or the Redemption Limitation Amendment Proposal, (ii) the structure of an initial business combination (iii) any redemptions or repurchases within the same taxable year as the initial business combination, (iv) if we do consummate an initial business combination, whether it is consummated in the current year or a later year, (v) if we do not consummate an initial business combination, whether we liquidate and dissolve in the current year, and (vi) the content of any further regulations and other guidance from the Department of the Treasury.

If the excise tax is due, it would be payable by us and not by the redeeming holder. The foregoing could cause a reduction in the cash available to us. In addition, if we are unable to complete an initial business combination during the current year and ultimately liquidate in a later taxable year, the excise tax imposed on redemptions in connection with the Extension Proposal and/or the Redemption Limitation Amendment Proposal could reduce the amount of cash available for our stockholders on liquidation.

In the event that the Extension is implemented, the proceeds deposited in the Trust Account and the interest earned thereon will not be used to pay for any excise tax due under the IR Act in connection with any redemptions of the public shares by the holders thereof exercising redemption rights, and the Company will pay any such excise tax from its funds remaining outside of the Trust Account. If such funds are insufficient the Internal Revenue Service, which we refer to as the “IRS”, might attempt to collect amounts due from our Trust Account or, in the event the Company dissolves, from stockholders to the extent of distributions received by them in such dissolution.

THE SPECIAL MEETING

Date, Time, Place and Purpose of the Special Meeting

The Special Meeting will be held in person or by proxy on April 16, 2024, at 10:00AM, Eastern Time, virtually via live webcast at https://www.cstproxy.com/altenergyacquisition/2024, to consider and vote upon the proposals to be put to the Special Meeting.

At the Special Meeting, you will be asked to consider and vote on proposals to:

Proposal No. 1—The Extension Proposal—a proposal to amend the Company’s Charter in the form set forth in Annex A of the accompanying proxy statement to extend the date by which the Company must (1) consummate a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination (an “initial business combination”) or (2) cease its operations except for the purpose of winding up if it fails to complete such initial business combination and redeem all of the Class A Common Stock from May 2, 2024 to November 2, 2024 and to allow the Board, without another stockholder vote, to elect to further extend the date to consummate an initial business combination after November 2, 2024 up to six times, by an additional month each time, upon two days’ advance notice prior to the applicable deadline, up to May 2, 2025.

Proposal No. 2—The Redemption Limitation Amendment Proposal—a proposal to amend the Charter in the form set forth Annex A of this proxy statement to eliminate from the Charter the limitation that the Company shall not redeem public shares to the extent that such redemption would cause the Company’s net tangible assets to be less than the Redemption Limitation. The Redemption Limitation Amendment would allow the Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation; and

Proposal No. 3—The Adjournment Proposal—a proposal to approve the adjournment of the Special Meeting to a later date or dates, if necessary or convenient, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the Extension Proposal and/or the Redemption Limitation Amendment Proposal, which will only be presented at the Special Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Special Meeting to approve the Extension Proposal and/or the Redemption Limitation Amendment Proposal, in which case the Adjournment Proposal will be the only proposal presented at the Special Meeting.

Voting Power; Record Date

Only stockholders of record of the Company as of the close of business on March 5, 2024, are entitled to notice of, and to vote at, the Special Meeting or any adjournment or postponement thereof. Each share of Common Stock entitles the holder thereof to one vote. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. On the record date, there were 7,327,428 shares of Common Stock issued and outstanding, including 7,077,478 of Class A Common Stock and 250,000 shares of Class B Common Stock. The Company’s warrants do not have voting rights in connection with the proposals.

Quorum and Vote of Stockholders

A quorum is the minimum number of shares required to be present at the Special Meeting for the Special Meeting to be properly held under our Charter and the DGCL. The presence, in person, by proxy, or if a corporation or other non-natural person, by its duly authorized representative or proxy, of the holders of a majority of the issued and outstanding Common Stock entitled to vote at the Special Meeting constitutes a quorum. Proxies that are marked “abstain” and proxies relating to “street name” shares that are returned to us but marked by brokers as “not voted” (so-called “broker non-votes”) will be treated as shares present for purposes of determining the presence of a quorum on all matters. If a stockholder does not give the broker voting

instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on “non-discretionary” matters. We believe each of the proposals constitutes a “non-discretionary” matter.

Votes Required

Approval of the Extension Proposal and the Redemption Limitation Amendment Proposal requires the affirmative vote of holders of at least sixty five percent (65%) of the shares of Common Stock issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so at the Special Meeting. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Special Meeting.

Approval of the Adjournment Proposal requires the affirmative vote of a majority of the shares of Common Stock issued and outstanding, represented in person or by proxy and entitled to vote thereon and who vote at the Special Meeting. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Special Meeting.

Voting

Our Board is asking for your proxy. Giving our Board your proxy means you authorize it to vote your shares at the Special Meeting in the manner you direct. You may vote for or withhold your vote for the proposal or you may abstain from voting. All valid proxies received prior to the Special Meeting will be voted. All shares represented by a proxy will be voted, and where a stockholder specifies by means of the proxy a choice with respect to any matter to be acted upon, the shares will be voted in accordance with the specification so made. If no choice is indicated on the proxy, the shares will be voted “FOR” each of the proposals and as the proxy holders may determine in their discretion with respect to any other matters that may properly come before the Special Meeting.

You can vote your shares at the Special Meeting in person or by proxy. You may attend the Special Meeting via live webcast. You will be able to attend the Special Meeting online, vote and submit your questions during the Special Meeting by visiting https://www.cstproxy.com/altenergyacquisition/2024. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage-paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the Special Meeting and vote in person, obtain a valid proxy from your broker, bank or nominee.

Proxies that are marked “abstain” and proxies relating to “street name” shares that are returned to us but marked by brokers as “not voted” (so-called “broker non-votes”) will be treated as shares present for purposes of determining the presence of a quorum on all matters. If a stockholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on “non-discretionary” matters. We believe each of the proposals constitutes a “non-discretionary” matter.

Stockholders who have questions or need assistance in completing or submitting their proxy cards should contact Jon Darnell by calling 203-299-1400 or by emailing info@altenergyacquisition.com.

Revocability of Proxies

Stockholders may send a later-dated, signed proxy card to the Company at 600 Lexington Avenue, 9th Floor, New York, New York, 10022, attn.: Corporate Secretary, so that it is received prior to the vote at the Special Meeting (which is scheduled to take place on April 16, 2024) or attend the Special Meeting virtually and vote. Stockholders also may revoke their proxy by sending a notice of revocation to the Company’s Corporate Secretary, which must be received prior to the vote at the Special Meeting.

PROPOSAL NO. 1—THE EXTENSION PROPOSAL

Background

On November 2, 2021, the Company completed its IPO of 23,000,000 units at a price of $10.00 per unit generating gross proceeds to the Company of $230,000,000 before underwriting discounts and expenses. Each unit consists of one share of Class A Common Stock and one-half of one public warrant. Each whole public warrant entitles the holder thereof to purchase one share of Class A Common Stock at a price of $11.50 per share, subject to certain adjustments. Simultaneously with the closing of the IPO, the Company completed the private placement of 10,800,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant to the Sponsor and B. Riley, generating gross proceeds to the Company of $10,800,000. A total of $234,600,000 of the net proceeds from the Company’s IPO and the sale of the Private Placement Warrants were placed in the Trust Account, with Continental acting as trustee.

On April 26, 2023 and April 27, 2024, the Company and the Sponsor entered into the Non-Redemption Agreements with the Holders. Pursuant to the Non-Redemption Agreements, such Holders agreed for the benefit of the Company to (i) vote such investors’ Class A Common Stock owned or acquired in favor of the proposal to amend the Company’s Amended and Restated Certificate of Incorporation to extend the time the Company is permitted to close an initial business combination and (ii) not redeem their Class A Common Stock in connection with such stockholder vote to amend the Company’s Amended and Restated Certificate of Incorporation. In connection with these commitments from the Holders, immediately prior to, and substantially concurrently with, the closing of an initial business combination, (i) the Sponsor (or its designees) will surrender and forfeit to the Company for no consideration the Forfeited Shares and (ii) the Company shall issue to the Holders a number of shares of Class A Common Stock equal to the Forfeited Shares.

On April 28, 2023, the Company held special meeting at which its stockholders approved the First Extension. In connection with the First Extension, stockholders elected to redeem an aggregate of 21,422,522 shares of Class A Common Stock. As a result, an aggregate of $222,365,779 (or approximately $10.38 per share) was released from the Trust Account to pay such stockholders. The Charter provides for the return of the IPO proceeds held in the Trust Account to the holders of public shares (as defined below) if the Company does not complete its initial business combination by May 2, 2024, unless otherwise extended.

On February 21, 2024, the Company entered into the Merger Agreement with Merger Sub and Car Tech.

The Charter currently provides that if the Company does not complete an initial business combination by May 2, 2024, the Company 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 subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining public stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

The Extension

The Company is proposing to amend its charter as set forth in the form attached to this proxy as Annex A to extend the date by which the Company must (1) consummate its initial business combination or (2) cease its operations except for the purpose of winding up if it fails to complete such initial business combination, and redeem all of the Class A Common Stock from May 2, 2024 to November 2, 2024, with optional additional extensions of up to six times by an additional month each time, at the option of the Board, until May 2, 2025.

Reasons for the Extension Proposal

The Charter currently provides that the Company has until May 2, 2024, to complete an initial business combination. While the Company and the other parties to the Merger Agreement are working toward satisfaction of the conditions to completion of the Business Combination, the Board has determined that there may not be sufficient time before May 2, 2024 to complete the Business Combination. Accordingly, the Board believes that in order to be able to complete the Business Combination, it is appropriate to continue the Company’s existence until the Extended Date or up to the Additional Extension Date, as applicable. The Board believes that the Business Combination offers an attractive investment for the Company’s stockholders. Therefore, the Board has determined that it is in the best interests of the Company’s stockholders to extend the date by which the Company must complete an initial business combination to the Extended Date and up to the Additional Extension Date, as applicable.

The Charter currently provides that if the Company does not complete an initial business combination by May 2, 2024, 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 subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining public stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

The Company believes that the provision of the Charter described in the preceding paragraph was included to protect the Company’s stockholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable initial business combination in the timeframe contemplated by the Charter. The Company also believes, however, that given the Company’s expenditure of time, effort and money on pursuing an initial business combination, its entry into the Merger Agreement and the Board’s belief that the Business Combination offers an attractive investment for the Company’s stockholders, the Extension is warranted.

The Company is not asking you to vote on any proposed initial 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 any proposed initial business combination when it is submitted to stockholders 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 earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable), divided by the number of then outstanding public shares, in the event the proposed initial business combination is approved and completed or the Company has not consummated an initial business combination by the Extended Date or the Additional Extension Date, as applicable.

The Sponsor

The Company’s Sponsor is AltEnergy Acquisition Sponsor LLC, a Delaware limited liability company. The Sponsor (whose members include certain of the Company’s directors and officers) currently owns an aggregate of 5,500,00 shares of Class A Common Stock and 250,000 shares of Class B Common Stock.

If the Extension Is Not Approved

If the Extension Proposal is not approved and we do not consummate an initial business combination by May 2, 2024, 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 subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining public stockholders and the Board, liquidate and dissolve, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

If the Extension Is Approved

If the Extension is approved, the Company will file an amendment to the Charter with the Delaware Secretary in the form of Annex A hereto to extend the time it has to complete an initial business combination until the Extended Date. The Company will remain a reporting company under the Exchange Act, and its units, Class A Common Stock and public warrants will remain publicly traded. The Company will then continue to work to consummate its initial business combination by the Extended Date or up to the Additional Extension Date, at the option of the Board.

You are not being asked to vote on an initial business combination, including 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 our initial business combination if and when it is submitted to stockholders and the right to redeem your public shares for cash in the event an initial business combination is approved and completed or the Company has not consummated an initial business combination by the Extended Date or the Additional Extension Date, as applicable.

If the Extension Proposal is approved, and the Extension is implemented, the amount held in the Trust Account will be reduced by withdrawals in connection with any stockholder redemptions. The Company cannot predict the amount that will remain in the Trust Account if the Extension is approved, and the amount remaining in the Trust Account may be significantly less than the $17,742,606.82 that was in the Trust Account as of February 29, 2024. The Company may need to obtain additional funds to complete its initial business combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

Redemption Rights

In connection with the approval of the Extension, each public stockholder may seek to redeem his, her or its public shares. 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 initial business combination, or if the Company has not consummated an initial business combination by the Extended Date.

TO DEMAND REDEMPTION, YOU MUST ENSURE YOUR BANK OR BROKER COMPLIES WITH THE REQUIREMENTS IDENTIFIED HEREIN, INCLUDING SUBMITTING A WRITTEN REQUEST THAT YOUR SHARES BE REDEEMED FOR CASH TO THE TRANSFER AGENT AND DELIVERING YOUR SHARES TO THE TRANSFER AGENT PRIOR TO 5:00 P.M. EASTERN TIME ON APRIL 11, 2024. You will only be entitled to receive cash in connection with a redemption of these shares if you continue to hold them until the effective date of the Extension and redemptions.

Pursuant to the Charter, a public stockholder may request that the Company redeem all or a portion of such public stockholder’s public shares for cash if the Extension and/or the Redemption Limitation Amendment Proposal is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

(i)

(ii)

Through the Deposit Withdrawal at Custodian (“DWAC”) system, this electronic delivery process can be accomplished by the stockholder, whether or not it is a record holder or its shares are held in “street name,” by contacting the transfer agent or its broker and requesting delivery of its shares through the DWAC system. Delivering shares physically may take significantly longer. In order to obtain a physical share 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 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 a tendering broker fee and the broker would 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 or over the brokers or DTC, and it may take longer than two weeks to obtain a physical share 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 share 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 the vote on the Extension will not be redeemed for cash held in the Trust Account. In the event that a public stockholder tenders its shares and decides prior to the vote at the Special 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 Special Meeting not to redeem your 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 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 will not be approved. The Company anticipates that a public stockholder who tenders shares for redemption in connection with the vote to approve the Extension would receive payment of the redemption price for such shares soon after the completion of the Extension. 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 earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable), divided by the number of then-issued and outstanding Class A Common Stock. Based upon the amount held in the Trust Account as of February 29, 2024, which was $17,742,606.82 and estimated interest income and taxes post-February 29, 2024, the Company estimates that the per-share price at which public shares may be redeemed from cash held in the Trust Account will be approximately $11.20 at the time of the Special Meeting. The closing price of a share of Class A Common Stock on March 22, 2024, was $11.25. The Company cannot assure stockholders that they will be able to sell their 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.

If you exercise your redemption rights, you will be exchanging your Common Stock for cash and will no longer own such shares. You will be entitled to receive cash for these shares only if you properly demand redemption and tender your share certificate(s) (if any) and other redemption forms to the Company’s transfer agent prior to the vote on the Extension Proposal. The Company anticipates that a public stockholder who tenders shares for redemption in connection with the vote to approve the Extension Proposal would receive payment of the redemption price for such shares soon after the completion of the Extension.

Required Vote

Approval of the Extension Proposal requires the affirmative vote of holders of at least sixty five percent (65%) of the Common Stock issued and outstanding, represented in person or by proxy and entitled to vote thereon and he Special Meeting. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Special Meeting. If the Extension is not approved and we do not consummate an initial business combination by May 2, 2024, 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 subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the quotient obtained by dividing (A) 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 the Company (less taxes payable), by (B) the total number of then-issued and outstanding public shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining public stockholders and the Board, liquidate and

dissolve, subject in each case to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

The Initial Stockholders are expected to vote all Common Stock owned by them in favor of the Extension. On the record date, the Initial Stockholders beneficially owned and were entitled to vote an aggregate 5,500,000 shares of Class A Common Stock and 250,000 shares of Class B Common Stock, constituting 20.00% of the Company’s issued and outstanding Common Stock. See the section entitled “Beneficial Ownership of Securities” for additional information.

In addition, subject to applicable securities laws (including with respect to material nonpublic information), the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates may (i) purchase public shares from institutional and other investors (including those who vote, or indicate an intention to vote, against any of the proposals presented at the Special Meeting, or elect to redeem, or indicate an intention to redeem, public shares), (ii) enter into transactions with such investors and others to provide them with incentives to not redeem their public shares, or (iii) execute agreements to purchase such public shares from such investors or enter into non-redemption agreements in the future. In the event that the Sponsor, the Company’s directors, officers, advisors or any of their respective affiliates purchase public shares in situations in which the tender offer rules restrictions on purchases would apply, they (a) would purchase the public shares at a price no higher than the price offered through the Company’s redemption process (i.e., approximately $11.20 per share, based on the amounts held in the Trust Account as of February 29, 2024); (b) would represent in writing that such public shares will not be voted in favor of approving the Extension; and (c) would waive in writing any redemption rights with respect to the public shares so purchased.

The purpose of such share purchases and other transactions would be to increase the likelihood of otherwise limiting the number of public shares electing to redeem.

Interests of the Sponsor and the Company’s Directors and Officers

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

•

If the Extension is not approved and we do not consummate an initial business combination by May 2, 2024, the 250,000 shares of Class B Common Stock and 5,500,000 shares of Class A Common Stock held by the Sponsor (whose members include certain of our directors and officers) will be worthless (as the Sponsor has waived liquidation rights with respect to such shares of Class B Common Stock);

•

In connection with the IPO, the Sponsor agreed that it will be liable under certain circumstances to ensure that the proceeds in the Trust Account are not reduced by the claims of any third party for services rendered or products sold to the Company or prospective target businesses with which the Company has entered into certain agreements;

•

All rights specified in the Charter relating to the right of officers and directors to be indemnified by the Company, and of the Company’s officers and directors to be exculpated from monetary liability with respect to prior acts or omissions, will continue after an initial business combination and, if the Extension is not approved and no initial business combination is completed by May 2, 2024, so that the Company liquidates, the Company will not be able to perform its obligations to its officers and directors under those provisions;

•

Other than as set forth below, none of the Company’s officers or directors has received any cash compensation for services rendered to the Company, and all of the current officers and directors are expected to continue to serve in their roles at least through the date of the Special Meeting and may continue to serve following any potential initial business combination and receive compensation thereafter;

•

The Company agreed to make payment to our Chief Financial Officer of $15,600 per month for his services prior to the consummation of its initial business combination. On April 1, 2022, the agreement with the Chief Financial Officer was amended so that he would be paid $10,400 per month, and an additional amount of $5,200 per month beginning April 1, 2022 through the consummation of the initial business combination will become payable to the Chief Financial Officer upon a successful consummation of a business combination. This agreement with the Chief Financial Officer was further amended on January 1, 2023, to provide that commencing on January 1, 2023, 100% of the consulting fee of $15,600 per month shall be accrued by the Company for the CFO’s benefit to be paid upon the closing of a business combination. If a successful business combination does not occur, the Company will not be required to pay any further amounts to the Chief Financial Officer. Upon completion of the initial business combination or liquidation, the Company will cease paying these monthly fees; and

•

The Sponsor and the Company’s officers and directors and their respective affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them related to identifying, investigating, negotiating and completing an initial business combination and, if the Extension is not approved and we do not consummate an initial business combination by May 2, 2024, they will not have any claim against the Trust Account for reimbursement so that the Company will most likely be unable to reimburse such expenses.

Potential Application of the Investment Company Act

As previously indicated, the Company completed its initial public offering (“IPO”) in November 2021. As a blank check company, the efforts of the Company’s board of directors and management have been focused on searching for a target business with which to consummate an initial business combination since the completion of its IPO. As of the date hereof, the Company has entered into the Merger Agreement with Car Tech and is focused on consummating the Business Combination.

On January 24, 2024, the SEC adopted the final rules (the “SPAC Final Rules”), relating to, among the others, the extent to which special purpose acquisition companies (“SPACs”) could become subject to regulation under the Investment Company Act of 1940 (the “Investment Company Act”). The SPAC Final Rules provide that whether a SPAC is an “investment company” under Section 3(a)(1)(A) of the subject to the Investment Company Act is based on particular facts and circumstances. A specific duration period of a SPAC is not the sole determinant, but one of the long-standing factors to consider in determination of a SPAC’s status under the Investment Company Act. A SPAC could be deemed as an investment company at any stage of its operation. The determination of a SPAC’s status as an investment company includes analysis of a SPAC’s activities, depending upon the facts and circumstances, including but not limited to, the nature of SPAC assets and income, the

activities of a SPAC’s officers, directors and employees, the duration of a SPAC, the manner a SPAC holding itself out to investors, and the merging with an investment company. The SPAC Final Rules were published in the Federal Register on February 26, 2024, and will become effective on July 1, 2024 (125 days after publication in the Federal Register).

There is currently uncertainty concerning the applicability of the Investment Company Act to a SPAC, including a company like ours. It is possible that a claim could be made that we have been operating as an unregistered investment company. If we were deemed to be an investment company for purposes of the Investment Company Act, we might be forced to abandon our efforts to complete an initial business combination and instead be required to liquidate the Company. If we are required to liquidate the Company, our investors would not be able to realize the benefits of owning stock in a successor operating business, including the potential appreciation in the value of our stock and warrants following such a transaction, and our warrants would expire worthless.

The funds in the Trust Account have, since our IPO, 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. The Company is currently assessing the relevant risks of being deemed to have been operating as an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act). The longer that the funds in the Trust Account are held in short- term U.S. government treasury obligations or in money market funds invested exclusively in such securities, the greater the risk that we may be considered an unregistered investment company, in which case we may be required to liquidate the Company. Accordingly, we may determine, in our discretion, to liquidate the securities held in the Trust Account at any time, and instead hold all funds in the Trust Account in cash, which would further reduce the dollar amount our public stockholders would receive upon any redemption or liquidation of the Company.

Recommendation

As discussed above, after careful consideration of all relevant factors, the Board has determined that the Extension Proposal is in the best interests of the Company and its stockholders. The Board has approved and declared advisable the adoption of the Extension Proposal.

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE EXTENSION PROPOSAL. OUR BOARD EXPRESSES NO OPINION AS TO WHETHER YOU SHOULD REDEEM YOUR PUBLIC SHARES.

PROPOSAL NO. 2—THE REDEMPTION LIMITATION AMENDMENT PROPOSAL

Overview

The Redemption Limitation Amendment Proposal asks the Company’s stockholders to amend the Charter pursuant to an amendment set forth in Annex A of the accompanying proxy statement to eliminate from the Charter the Redemption Limitation in order to allow the Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation.

Reasons for the Redemption Limitation Amendment Proposal

The Board believes the opportunity to consummate an initial business combination is in the best interests of the Company and its stockholders.

If the Redemption Limitation Amendment Proposal is not approved and there are significant requests for redemption such that the Redemption Limitation would be exceeded, the Redemption Limitation would prevent the Company from being able to consummate the Business Combination. The Company believes that the Redemption Limitation is not needed. The purpose of such limitation was initially to ensure that the Company did not become subject to the SEC’s “penny stock” rules. Because the public shares would not be deemed to be “penny stock” as such securities are listed on a national securities exchange, the Company is presenting the Redemption Limitation Amendment Proposal to facilitate the consummation of the Business Combination. If the Redemption Limitation Amendment Proposal is not approved and there are significant requests for redemption such that the Company’s net tangible assets would be less than $5,000,001 upon the consummation of the Business Combination, the Charter would prevent the Company from being able to consummate the Business Combination even if all other conditions to closing are met.

If the Redemption Limitation Amendment Proposal Is Not Approved

If the Redemption Limitation Amendment Proposal is not approved, the Company will not redeem public shares to the extent that accepting all properly submitted redemption requests would exceed the Redemption Limitation. In the event that the Redemption Limitation Amendment Proposal is not approved and the Company receives notice of redemptions of public shares approaching or in excess of the Redemption Limitation, the Company and/or the Sponsor may take action to increase the Company’s net tangible assets to avoid exceeding the Redemption Limitation.

If the Redemption Limitation Amendment Proposal Is Approved

If the Redemption Limitation Amendment Proposal is approved, the Company will file a notice of the special resolution amending the Charter with the Delaware Secretary of State in the form attached in Annex A hereto to eliminate the Redemption Limitation from the Charter.

Vote Required for Approval

Recommendation of the Board

As discussed above, after careful consideration of all relevant factors, the Board has determined that the Redemption Limitation Amendment Proposal is in the best interests of the Company and its stockholders. The Board has approved and declared advisable the adoption of the Redemption Limitation Amendment Proposal.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE REDEMPTION LIMITATION AMENDMENT PROPOSAL.

PROPOSAL NO. 3—THE ADJOURNMENT PROPOSAL

Overview

The Adjournment Proposal, if adopted, will allow our Board to adjourn the Special 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 Extension Proposal and/or the Redemption Limitation Amendment Proposal. In no event will our Board adjourn the Special Meeting beyond May 16, 2024.

Consequences if the Adjournment Proposal is Not Approved

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

Vote Required for Approval

The approval of the Adjournment Proposal requires the affirmative vote of the majority of the votes cast by stockholders represented in person or by proxy at the Special Meeting. Accordingly, if a valid quorum is otherwise established, a stockholder’s failure to vote by proxy or online at the Special Meeting will have no effect on the outcome of any vote on the Adjournment Proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the outcome of the Adjournment Proposal.

Recommendation of the Board

As discussed above, after careful consideration of all relevant factors, our Board has determined that the Adjournment Proposal is in the best interests of the Company and its stockholders. Therefore, if there are insufficient votes for, or otherwise in connection with, the approval of the Extension Proposal and/or the Redemption Limitation Amendment Proposal, our Board will approve and declare advisable adoption of the Adjournment Proposal.

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE ADJOURNMENT PROPOSAL

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR THE REDEMPTIONS

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 Proposal. This summary is based upon the Internal Revenue Code of 1986, as amended, which we refer to as the “Code”, the final, temporary and proposed regulations promulgated by the U.S. Treasury Department, current administrative interpretations and practices of 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 subject to special tax rules (e.g., financial institutions or financial services entities, insurance companies, mutual funds, pension plans, S corporations, broker-dealers, dealers or 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)) and investors 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, investors subject to the applicable financial statement accounting rules of Section 451(b) of the Code, persons who received their shares of our Class A common stock as compensation, governments or agencies or instrumentalities thereof, “specified foreign corporations” (including “controlled foreign corporations”), “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax, investors 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 or former long-term residents of the U.S., investors that actually or constructively own 5 percent or more of the Class A common stock of the Company (except as otherwise discussed below), and 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 our 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 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 Treasury regulations to be treated as a United States person.

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 our 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 our shares outstanding 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 our 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 which could be acquired pursuant to the exercise of the warrants. In order to meet the substantially disproportionate test, the percentage of our 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 our 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 our stock actually and constructively owned by the U.S. Holder are redeemed or (ii) all of the shares of our 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 us. Whether the redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in us 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 below under “U.S. Federal Income Tax Considerations to U.S. Holders—Taxation of Distributions.”

U.S. Holders of our 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, taxable exchange or other taxable disposition of Class A common stock, a U.S. Holder must treat any gain or loss recognized as capital gain or loss in an amount equal to the difference between the amount of cash and the U.S. Holder’s adjusted tax basis in the shares of Class A common stock redeemed. 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. It is unclear, however, whether the redemption rights described herein with respect to our Class A common stock may have suspended the running of the applicable holding period for this purpose. 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. U.S. Holders who hold different blocks of our Class A common stock (shares of our Class A common stock purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them.

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 generally will constitute dividends for United States federal income tax purposes to the extent paid from our 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 our 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 under “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 we pay 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 (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), and provided certain holding period requirements are met, dividends we pay to a non-corporate U.S. Holder generally will constitute “qualified dividends” that will be taxable at a reduced rate. It is unclear whether the redemption rights with respect to our Class A common stock described herein may prevent a U.S. Holder from satisfying the applicable holding period requirements with respect to the dividends received deduction or the preferential tax rate on qualified dividend income, as the case may be.

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

This section is addressed to Non-U.S. Holders of our 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 “Non-U.S. Holder” is a beneficial owner (other than a partnership) that so redeems its Class A common stock of the Company and for U.S. federal income tax purposes is:

•

a non-resident alien individual, other than certain former citizens and residents of the United States subject to U.S. tax as expatriates;

•

a foreign corporation; or

•

an estate or trust that 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 under “U.S. Federal Income Tax Considerations to U.S. Holders”.

Non-U.S. Holders of our 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 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 (including any gain realized in connection with the redemption); or

•

we are or have 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 our Class A common stock, and, in the case where shares of our 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 our 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 our Class A common stock. We do not believe we are or have been a U.S. real property holding corporation.

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 we make to a Non-U.S. Holder of shares of our Class A common stock, to the extent paid out of our 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, we 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 (usually on an IRS Form W-8BEN or W-8BEN-E). 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 our 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 under “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”. It is possible that because the applicable withholding agent may not be able to determine the proper characterization of a redemption of a Non-U.S. Holder’s our Class A common stock, the withholding agent might treat the redemption as a distribution subject to withholding tax. A Non-U.S. Holder may generally obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Dividends we pay 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).

Information Reporting and Backup Withholding

Dividend payments with respect to our Class A common stock and proceeds from the sale of our Class A common stock may be subject to information reporting to the IRS and possible United States backup withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a holder’s United States federal income tax liability, and a holder generally may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Amounts treated as dividends that are paid to a Non-U.S. Holder are generally subject to reporting on IRS Form 1042-S even if the payments are exempt from withholding. A Non-U.S. Holder generally will eliminate any other requirement for information reporting and backup withholding by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

FATCA Withholding Taxes

Provisions commonly referred to as “FATCA” impose withholding of 30% on payments of dividends (including amounts treated as dividends received pursuant to a redemption of stock) on our Class A common stock. In general, no such withholding will be required with respect to a U.S. Holder or an individual Non-U.S. Holder that timely provides the certifications required on a valid IRS Form W-9 or W-8, respectively. Holders potentially subject to withholding include “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies (typically certified as to by the delivery of a properly completed IRS Form W-8BEN-E). If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Non-U.S. Holders should consult their tax advisers regarding the effects of FATCA on a redemption of our Class A common stock.

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 Extension Proposal.

BENEFICIAL OWNERSHIP OF SECURITIES

The following table sets forth information available to us as of March 22, 2024, with respect to our Common Stock held by:

•

each person known by us to be the beneficial owner of more than 5% of our Common Stock;

•

each of our executive officers and directors; and

•

all our executive officers and directors as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or will become exercisable within 60 days. Except as described in the footnotes below and subject to applicable community property laws and similar laws, we believe that each person listed below has sole voting and investment power with respect to such shares.

In the table below, percentage ownership is based on 7,327,428 shares of common stock issued and outstanding as of March 22, 2024, consisting of 7,077,478 shares of Class A common stock and 250,000 shares of Class B common stock. On all matters to be voted upon, the holders of the Common Stock vote together as a single class. The table below does not include any Common Stock underlying our outstanding warrants because such securities are not exercisable within 60 days of March 22, 2024.

STOCKHOLDER PROPOSALS

If the Extension Proposal is approved and the Extension is implemented, the Company intends to hold a special meeting of stockholders for the purpose of approving a proposed business combination and related matters, including the election of directors. Accordingly, the Company’s next annual meeting of stockholders would be held at a future date to be determined by the post business-combination company. The Company expects that it would notify stockholders of the deadline for submitting a proposal for inclusion in the proxy statement for its next annual meeting following the completion of an initial business combination. For any proposal to be considered for inclusion in our Proxy Statement for submission to the stockholders at the Company’s next annual meeting of stockholders, it must be submitted in writing and comply with the requirements of Rule 14a-8 of the Exchange Act and our bylaws.

If the Extension Proposal is not approved and the Company liquidates, there will be no further annual meetings of the Company.

DELIVERY OF DOCUMENTS TO STOCKHOLDERS

For stockholders receiving printed proxy materials, 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 stockholders prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, the stockholders should follow the instructions described below. Similarly, if an address is shared with another stockholder and together both of the stockholders would like to receive only a single set of our disclosure documents, the stockholders should follow these instructions:

•

If the shares are registered in the name of the stockholder, the stockholder should contact us at our offices at 600 Lexington Avenue, 9th Floor, New York, New York 10022, or (203) 299-1400, to inform us of his or her request; or

•

If a bank, broker or other nominee holds the shares, the stockholder should contact the bank, broker or other nominee directly.

WHERE YOU CAN FIND MORE INFORMATION

We file reports, proxy statements and other information with the SEC as required by the Exchange Act. You can read the Company’s SEC filings, including this proxy statement, over the Internet at the SEC’s website at www.sec.gov.

If you would like additional copies of this proxy statement or if you have questions about the proposals to be presented at the Special Meeting, you should contact the Company at the following address and telephone number:

CERTIFICATE OF INCORPORATION

Except for the withdrawal of interest to pay franchise and income taxes, none of the funds held in the Trust Account (including the interest earned on the funds held in the Trust Account) will be released from the Trust Account until the earliest to occur of (i) the completion of the initial Business Combination, (ii) the redemption of 100% of the Offering Shares (as defined below) if the Corporation is unable to complete its initial Business Combination on or before (a) November 2, 2024 (the “Initial Redemption Date”) or (b) May 2, 2025 (the “Extended Redemption Date”), in the event that the Directors resolve by resolutions of the Board, to extend the amount of time to complete a Business Combination for up to six (6) times for an additional one (1) month each time, and (iii) the redemption of shares in connection with a vote seeking to amend any provisions of the Amended and Restated Certificate relating to stockholders’ rights or pre-initial Business Combination activity (as described in Section 8.7).
