Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Organization and Business Operations and Liquidity	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS AND LIQUIDITY AltEnergy Acquisition Corp. (the “Company”) was incorporated in Delaware on February 9, 2021. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of December 31, 2024, the Company had not commenced any operations. All activity for the period from February 9, 2021 (inception) through December 31, 2024 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described below. The Company will not generate any operating revenues until after completion of the Business Combination at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the net proceeds derived from the Initial Public Offering. The Company has selected December 31st as its fiscal year end. The registration statement for the Company’s Initial Public Offering was declared effective on October 28, 2021. On November 2, 2021, the Company consummated the Initial Public Offering of 20,000,000 units (“Units” and, with respect to the common stock included in the Units being offered, the “Public Shares”), generating gross proceeds of $200,000,000, which is described in Note 3. On November 2, 2021, the underwriters purchased an additional 3,000,000 Units pursuant to the exercise of the over-allotment option. The Units were sold at an offering price of $10.00 per Unit, generating additional gross proceeds to the Company of $30,000,000. Simultaneously with the closing of the Initial Public Offering and the exercise by the underwriters of the over-allotment option, the Company consummated the private sale (the “Private Placement”) of an aggregate of 12,000,000 warrants (the “Private Placement Warrants”) allocating 11,600,000 warrants to AltEnergy Acquisition Sponsor LLC (the “Sponsor”) (including 1,200,000 warrants purchased in connection with the exercise of the over-allotment option) and 400,000 warrants to an affiliate of the underwriter at a purchase price of $1.00 per Private Placement Warrant, generating gross proceeds to the Company in the amount of $12,000,000. Following the closing of the Initial Public Offering on November 2, 2021, an amount of $234,600,000 ($10.20 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement was placed in a trust account with Continental Stock Transfer & Trust Company acting as trustee (the “ Trust Account ”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account, as described below. As of November 2, 2021, transaction costs amounted to $13,355,589 consisting of $4,600,000 of underwriting fees, $8,050,000 of deferred underwriting fees payable (which are held in the Trust Account) and $705,589 of costs related to the Initial Public Offering. On April 28, 2023, following the approval by the stockholders of the Company at a special meeting of stockholders the Company filed an amendment to the Company’s Amended and Restated Certificate of Incorporation with the Secretary of State of Delaware to extend the date from May 2, 2023 (18 months from the closing of the Initial Public Offering), to May 2, 2024 (30 months for the closing of the Initial Public Offering) (the “ Extension ,”) by which the Company must (1) consummate a 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 Shares included as part of the units sold in the Company’s Initial Public Offering. Stockholders holding 21,422,522 Class A Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Company’s Trust Account in connection with the Extension. As a result, $222,484,624 (approximately $10.38 per share) was removed from the Trust Account on or about May 15, 2023 to pay such holders, and an additional $855,762 (including $100,000 reserved to pay dissolution costs and expenses discussed below) was removed from the Trust Account on or about May 9, 2023 and deposited into a restricted investment account. On April 16, 2024, the Company held a special meeting of stockholders (the “April 2024 Special Meeting”). As of March 5, 2024, the record date of the April 2024 Special Meeting, there were 7,327,478 issued and outstanding shares of common stock of the Company, par value $0.0001 per share (the “Common Stock”) comprised of 7,077,478 shares of the Company’s Class A common stock, par value $0.0001 per share (“Class A Shares”), and 250,000 shares of the Company’s Class B common stock, par value $0.0001 per share. At the April 2024 Special Meeting, the Company’s 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 (the “Amendment”) to extend the date 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”); 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 Shares included as part of the units sold in the Company’s initial public offering. On April 17, 2024, to effectuate the Extension, the Company filed the Amendment with the Secretary of State of the State of Delaware. On October 30, 2024, in accordance with the Amendment, the Board elected to further extend the date to consummate an initial business combination from November 2, 2024, to December 2, 2024 (the “First Optional Extension Date”), and on October 31, 2024, the Company filed a Current Report on Form 8-K with the Securities and Exchange Commission to effect the required two days’ notice. At the April 2024 Special Meeting, the Company’s stockholders also approved a proposal to amend our amended and restated certificate of incorporation to eliminate 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 our net tangible assets to be less than $5,000,001 (the “Redemption Limitation”) to allow us to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation. Stockholders holding 839,332 Class A Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Company’s trust account (“Trust Account”) in connection with the Extension. As a result, $9,513,007 (approximately $11.33 per share) was removed from the Trust Account to pay such holders. Pursuant to the amendment to AltEnergy’s Amended and Restated Certificate of Incorporation referred to above, the Board (i) on October 30, 2024, approved an extension of the date by which AltEnergy is required to complete an initial business combination from November 2, 2024 to December 2, 2024; (ii) on November 25, 2024, approved an extension of the date by which AltEnergy is required to complete an initial business combination from December 2, 2024 to January 2, 2025; (iii) on December 20, 2024, approved an extension of the date by which AltEnergy is required to complete an initial business combination from January 2, 2025 to February 2, 2025; (iv) January 28, 2025, approved an extension of the date by which AltEnergy is required to complete an initial business combination from February 2, 2025 to March 2, 2025; (v) on February 25, 2025, approved an extension of the date by which AltEnergy is required to complete an initial business combination from March 2, 2025 to April 2, 2025; and (vi) on March 26, 2025, approved an extension of the date by which AltEnergy is required to complete and initial business combination from April 2, 2025 to May 2, 2025. The Company has scheduled a meeting for April 23, 2025 for the purpose of amending the Amended and Restated Certificate of Incorporation to further extend the date by which the Company is required to complete an initial business combination from May 2, 2025 to May 1, 2026. As of December 31, 2024 there was $$8,544,857 (or approximately $11.58 per share) held in the Trust Account. Cash of $18,458 was held outside of the Trust Account on December 31, 2024 and was available for working capital purposes. As of December 31, 2024, there was $101,511 held in the restricted investment account of which $100,000 is reserved to pay dissolution costs and expenses in the event the Company fails to complete in initial business combination and is dissolved. To the extent such funds in the restricted investment account are insufficient (less than $100,000), additional funds will be dispersed from the Trust up to a combined total of $100,000. Any amount in the restricted investment account in excess of $100,000 will be for the benefit of the Trust. If an initial business combination is consummated all funds then held in the restricted investment account, including amounts previously reserved to pay dissolution costs and expenses in the event the Company fails to complete an initial business combination will be for the benefit of the Trust. As described in Note 6, the $8,050,000 deferred underwriting fees are contingent upon the consummation of the Business Combination. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account). The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). Upon the closing of the Initial Public Offering, management agreed that an amount equal to at least $10.20 per Unit sold in the Initial Public Offering, including proceeds of the Private Placement Warrants, will be held in a trust account, located in the United States and invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting certain conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the funds held in the Trust Account, as described below. The Company will provide the holders of the outstanding Public Shares (the “Public Stockholders”) with the opportunity to redeem all or a portion of their Public Shares either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer in connection with the Business Combination. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.20 per Public Share, plus any pro rata interest then in the Trust Account, net of taxes payable). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. The Public Shares subject to redemption were recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Accounting Standards Codification (“ASC”) Topic 480 “ Distinguishing Liabilities from Equity .” If the Company seeks stockholder approval of the Business Combination, the Company will proceed with a Business Combination if a majority of the outstanding shares voted are voted in favor of the Business Combination, or such other vote as required by law or stock exchange rule. If a stockholder vote is not required by applicable law or stock exchange listing requirements and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its amended and restated certificate of incorporation, as amended (the “Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by applicable law or stock exchange listing requirements, or the Company decides to obtain stockholder approval for business or other reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each Public Stockholder may elect to redeem their Public Shares without voting, and if they do vote, irrespective of whether they vote for or against the proposed transaction. Notwithstanding the foregoing, if the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Certificate of Incorporation provides that a Public Stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), will be restricted from redeeming its shares with respect to more than an aggregate of 20% of the Public Shares, without the prior consent of the Company. The holders of the Founder Shares have agreed (a) to waive their redemption rights with respect to the Founder Shares and Public Shares held by them in connection with the completion of a Business Combination and (b) not to propose an amendment to the Certificate of Incorporation (i) to modify the substance or timing of the Company’s obligation to allow redemptions in connection with a Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or (ii) with respect to any other provision relating to stockholders’ rights or pre-business combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. If the Company has not completed a Business Combination on or prior to May 2, 2025 or such later date if the date is further extended (the “Combination Period”), 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, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to pay taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period. The holders of the Founder Shares have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the holders of Founder Shares acquire Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit ($10.00). In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.20 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.20 per public Share due to reductions in the value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except for the Company’s independent registered accounting firm), prospective target businesses and other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Going Concern, Liquidity and Management’s Plan As of December 31, 2024 there was $8,544,857 (or approximately $11.58 per share) held in the Trust Account. Cash of $18,458 was held outside of the Trust Account on December 31, 2024 and was available for working capital purposes. As of December 31, 2024, there was $101,511 held in the restricted investment account which together with interest earned thereon and after payment of associated taxes and account fees up to $100,000 is reserved to pay dissolution costs and expenses in the event the Company fails to complete an initial business combination and is dissolved. To the extent such funds in the restricted investment account are insufficient (less than $100,000), additional funds will be dispersed from the Trust up to a combined total of $100,000. Any amount in the restricted investment account in excess of $100,000 will be for the benefit of the Trust. If an initial business combination is consummated all funds then held in the restricted investment account, including amounts previously reserved to pay dissolution costs and expenses in the event the Company fails to complete an initial business combination will be for the benefit of the Trust. As described in Note 6, the $8,050,000 deferred underwriting fees are contingent upon the consummation of the Business Combination. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “ Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern ,” management has determined that the Company may lack the financial resources it needs to sustain operations for a reasonable period of time, which is considered to be one year from the issuance date of the financial statements. Management has also determined that, in accordance with the Company’s amended and restated articles of incorporation, if the Company is unsuccessful in consummating an initial business combination by May 2, 2025 (unless such date is further extended by an amendment to the Company’s articles of incorporation), the Company will cease all operations, redeem the public shares, and thereafter liquidate and dissolve. These conditions raise substantial doubt about the ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The accompanying financial statements have been prepared in conformity with GAAP, which contemplate continuation of the Company as a going concern. The Company intends to use substantially all of the funds held in the Trust Account after payments on account of any redemptions, including any amounts representing interest earned on the Trust Account, excluding the deferred underwriting commissions, to complete an initial business combination. To the extent that capital stock or debt is used, in whole or in part, as consideration to complete an initial business combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business. If an initial business combination agreement requires the Company to use a portion of the cash in the Trust Account to pay the purchase price or requires the Company to have a minimum amount of cash at closing (including any cash available from the Trust Account), the Company will need to arrange for third-party financing. The Company is required to complete an initial business combination on or prior to May 2, 2025 (unless such date is further extended by an amendment to the Company’s Certificate of Incorporation). If the Company is unable to complete an initial business combination on or prior to such date, 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, and subject to having lawfully available funds therefore, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then-outstanding public shares, which redemption will completely extinguish the public stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Nasdaq Delisting 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 Notice was only a notification of deficiency, not of imminent delisting, and had no current effect on the listing or trading of the Company’s securities on the Nasdaq Global Market. The Company disclosed its receipt of the Notice pursuant to a Form 8-K filed on October 13, 2023, as required by NASDAQ rules. On November 20, 2023, the Company submitted a plan to regain compliance within the required timeframe. On May 7, 2024, the Company received a written notice (the “MVPHS Notice”) from the Nasdaq Listing Qualifications Department (the “Staff”) indicating that the Company was not in compliance with Nasdaq Listing Rule 5450(b)(2)(C), which requires the Company to maintain a Market Value of Publicly Held Shares (“MVPHS”) of no less than $15 million for continued listing on the Nasdaq Global Market. The Notice was only a notification of deficiency, not of imminent delisting, and had no current effect on the listing or trading of the Company’s securities on the Nasdaq Global Market. In accordance with Nasdaq Listing Rule 5810(c)(3)(D), the Company had 180 calendar days, or until November 3, 2024, to regain compliance. The MVPHS Letter noted that to regain compliance, the Company’s MVPHS must close at or above $15 million for a minimum of ten consecutive business days during the compliance period. The MVPHS Letter further noted that if the Company is unable to satisfy the MVPHS requirement prior to such date, the Company may be eligible to transfer the listing of its securities to The Nasdaq Capital Market (provided that the Company then satisfied the requirements for continued listing on that market). The Company disclosed its receipt of the MVPHS Notice pursuant to a Form 8-K filed on May 13, 2024, as required by Nasdaq rules. In connection with the foregoing, the Company transferred from the Nasdaq Global Market to the Nasdaq Capital Market. On October 29, 2024, the Company received a written notice from Nasdaq that the Company’s securities would be delisted from The Nasdaq Stock Market by reason of the failure of the Company to complete its initial business combination by October 28, 2024 (36 months from the effectiveness of the Company’s IPO registration statement) as required by IM-5101-2. Accordingly, trading in the Company’s Class A Common Stock, Units and Warrants was suspended at the opening of business on November 5, 2024 and Form 25-NSE was filed with the Securities and Exchange Commission, which removed the Company’s securities from listing and registration on The Nasdaq Stock Market. The Company’s Class A Common Stock, Units and Warrants continue to be traded in the over-the-counter market. Risks and Uncertainties Management continues to evaluate the impact of global conflicts and any further escalation of hostilities related thereto, terrorist attacks, natural disasters or a significant outbreak of other infectious diseases, on the industry and has concluded that while it is reasonably possible that such events could have a negative effect on the Company’s financial position, results of its operations and/or search for a target, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of these uncertainties.
