Overview

We are a blank check company incorporated as a Delaware corporation and formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the "initial business combination"). We intend to effectuate our business combination using cash from the proceeds of our initial public offering and the private placement that occurred simultaneously with the completion of our initial public offering to the extent any funds remain available after any redemptions effected in connection with the initial business combination, our capital stock, debt or a combination of cash, stock and debt.

We continue to pursue an initial business combination. In connection with the proposed initial business combination we expect to issue additional shares to the owners of the target or other investors, with the following consequences:

Similarly, if in connection with an initial business combination we issue debt securities or otherwise incur significant debt to bank or other lenders or the owners of a target, it could result in:

In the short term, we are incurring costs in the pursuit of our initial business combination plans. We cannot assure you that our plans to raise capital or to complete our initial business combination will be successful.

Extension of Combination Period

April 2023 Special Meeting

On April 28, 2023, the Company held a special meeting of stockholders (the "April 2023 Special Meeting"). As of April 10, 2023, the record date of the April 2023 Special Meeting, there were 28,750,000 issued and outstanding shares of common stock, par value $0.0001 per share (the "Common Stock") comprised of 23,000,000 shares of the Company's Class A common stock, par value $0.0001 per share ("Class A Shares"), and 5,750,000 shares of the Company's Class B common stock, par value $0.0001 per share. At the April 2023 Special Meeting, the Company's stockholders approved the proposal to file an amendment to AltEnergy's Amended and Restated Certificate of Incorporation with the Secretary of State of Delaware (the "Amendment") to extend the date from May 2, 2023, to May 2, 2024 (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 IPO that was consummated on November 2, 2021. On April 28, 2023, to effectuate the Extension, the Company filed the Amendment with the Secretary of State of the State of Delaware. 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 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 was removed from the Trust Account on or about May 9, 2023. As of December 31, 2023 there was $17,591,536 (or approximately $11.15 per share of Class A common stock that is subject to redemption) held in the Trust Account.

On April 28, 2023, following the April 2023 Special Meeting, 5,500,000 shares of Class B Common Stock were converted into Class A Shares, which Class A Shares are not subject to redemption.

April 2024 Special Meeting

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 comprised of 7,077,478 shares of the Company's 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, AltEnergy'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 IPO that was consummated on November 2, 2021. On April 17, 2024, to effectuate the Extension, the Company filed the Amendment with the Secretary of State of the State of Delaware.

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.

As a result of the April 2024 Special Meeting, stockholders holding 839,332 Class A Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account in connection with the Extension. As a result, $9,513,007 (approximately $11.33 per share) was removed from the Trust Account on or about April 23, 2024 to pay such holders. As of April 30, 2024 there was $8,344,700 (or approximately $11.30 per share of Class A common stock that is subject to redemption) held in the Trust Account.

Additional Extensions

Pursuant to the amendment to the Company'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 the Company 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 the Company 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 the Company is required to complete an initial business combination from January 2, 2025 to February 2, 2025; 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 an initial business combination from April 2, 2025 to May 2, 2025.

April 2025 Special Meeting

On April 23, 2025, the Company held a special meeting of stockholders (the "April 2025 Special Meeting"). As of March 24, 2025, the record date of the April 2025 Special Meeting, there were 6,488,146 issued and outstanding shares of common stock of the Company, par value $0.0001 per share (the "Common Stock") comprised of 6,238,146 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 2025 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, 2025 to May 1, 2026 (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 25, 2025, to effectuate the Extension, the Company filed the Amendment with the Secretary of State of the State of Delaware.

In connection with the April 2025 Special Meeting, stockholders holding 221,949 Class A Shares exercised their right to redeem such shares for a pro rata portion of the funds then held in the Company's Trust Account. As a result, $2,603,924.73 (approximately $11.73 per share) was removed from the Trust Account to pay such holders as of April 30, 2025.

Results of Operations

We have neither engaged in any operations nor generated any revenues to date. Our only activities since inception were organizational activities, those necessary to prepare for the initial public offering, and identifying a target company for a business combination. We do not expect to generate any operating revenues until after the completion of our initial business combination. We generate non-operatingincome in the form of interest income on marketable securities. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses in connection with completing a business combination.

For the three months ended September 30, 2025 and 2024, we had a net loss of $380,642 and $691,836, respectively. Our net loss for the three months ended September 30, 2025 consisted of interest income earned on the funds held in Trust in the amount of $63,653, interest income earned on the operating account of $1,017 offset by operating expenses that total $360,607, interest expense of $58,895, a loss of $19,500 on the change in fair value of the derivative warrant liabilities associated with the warrants issued as part of the Units sold in the Public Offering and the Private Placement Warrants, and income tax expense of $6,310. Our net loss for the three months ended September 30, 2024 consisted of interest income earned on the funds held in Trust in the amount of $109,352, a gain of $235,000 on the change in fair value of the derivative warrant liabilities associated with the warrants issued as part of the Units sold in the Public Offering and the Private Placement Warrants, interest income earned on the operating account of $1,276 offset by operating expenses that total $999,367, interest expense of $20,879 and income tax expense of $17,218.

For the nine months ended September 30, 2025 and 2024, we had a net loss of $2,158,659 and $2,120,903, respectively. Our net loss for the nine months ended September 30, 2025 consisted of interest income earned on the funds held in Trust in the amount of $224,617, interest income earned on the operating account of $3,068 offset by operating expenses that total $1,681,707, interest expense of $195,169, a loss of $503,100 on the change in fair value of the derivative warrant liabilities associated with the warrants issued as part of the Units sold in the Public Offering and the Private Placement Warrants, and income tax expense of $6,368. Our net loss for the nine months ended September 30, 2024 consisted of interest income earned on the funds held in Trust in the amount of $478,018, a gain of $705,000 on the change in fair value of the derivative warrant liabilities associated with the warrants issued as part of the Units sold in the Public Offering and the Private Placement Warrants interest income earned on the operating account of $3,135 offset by operating expenses that total $3,188,033, interest expense of $48,674 and income tax expense of $70,349.

Going Concern Considerations, Liquidity and Capital Resources

As of September 30, 2025 there was $6,149,592 (or approximately $11.91 per share) held in the Trust Account. Cash of $1,907 was held outside of the Trust Account on September 30, 2025 and was available for working capital purposes. As of September 30, 2025, there was $100,331 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 to the financial statements, the $8,050,000 deferred underwriting fees are contingent upon the consummation of an initial business combination.

In connection with the Company's assessment of going concern considerations in accordance with Financial Accounting Standard Board's ("FASB") ASC Subtopic 205-40,"Presentation of Financial Statements - 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 Certificate of Incorporation, unless the Company completes a business combination by May 1, 2026, 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.

If the Company completes an initial business combination, the Company does not believe that there will be any funds held in the Trust Account, including any amounts representing interest earned on the Trust Account after payment of the deferred underwriting commissions, and amounts paid to redeem public shares. If an initial business combination agreement requires the Company to have a minimum amount of cash at closing, the Company will need to arrange for third-party financing to meet such requirement.

We may have insufficient funds available to operate our business prior to our business combination. Moreover, we may need to obtain additional financing either to complete our business combination or because we become obligated to redeem a significant number of the remaining public shares upon completion of our business combination, in which case we may issue additional securities or incur debt in connection with such business combination. Subject to compliance with applicable securities laws, we would only complete such financing simultaneously with the completion of our business combination. If we are unable to complete our business combination because we do not have sufficient funds available to us, we will be forced to cease operations and liquidate the Trust Account. In addition, following our business combination, if cash on hand is insufficient, we may need to obtain additional financing in order to meet our obligations.

As of September 30, 2025, we had cash of $102,238 held outside the Trust Account, of which $100,331 is held in a restricted account and reserved to pay taxes and dissolution costs and expenses in the event the Company fails to complete in initial business combination and is dissolved. We intend to use all of such funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a business combination. The balance will be used to pay accrued taxes.

Convertible Working Capital Loan

In order to fund working capital deficiencies or finance transaction costs in connection with a business combination, the Sponsor or an affiliate of the Sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete a business combination, we would repay such loaned amounts. In the event that a business combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment. Up to $1,500,000 of such working capital loans may be convertible into private placement units at a price of $1.00 per warrant at the option of the lender. As of September 30, 2025 and December 31, 2024, there was no outstanding balance.

Loan Payable - Sponsor

Additionally, per a Commitment Letter, dated July 19, 2022, the Sponsor undertook upon the Company's written request to make available an aggregate amount of up to $250,000 to provide the Company funds for working capital purposes to ensure that the Company would continue as a going concern for at least 12 months. A second Commitment Letter was dated May 4, 2023 for up to an additional $750,000. A third Commitment Letter was dated December 20, 2023 for up to an additional $800,000. A fourth commitment letter was dated July 08, 2024 for up to an additional $750,000. A fifth commitment letter was dated March 04, 2025 for up to an additional $475,000. The Sponsor is charging interest at the mid-termapplicable federal rate at the time of funding. During the nine months ended September 30, 2025, the Sponsor loaned an aggregate of $559,000 to the Company for working capital purpose, respectively. The Sponsor loaned an additional $40,000 on each of October 08, 2025 and October 24, 2025, and an additional $51,000 on November 05, 2025. As of September 30, 2025 and December 31, 2024, $2,894,000 and $2,335,000 remained outstanding, respectively. As of September 30, 2025 and December 31, 2024, there was accrued interest of $177,685 and $91,688, respectively.

Off-BalanceSheet Financing Arrangements

We have no obligations, assets or liabilities, which would be considered off-balancesheet arrangements as of September 30, 2025. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balancesheet arrangements. We have not entered into any off-balancesheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financialassets.

Contractual Obligations

We do not have any long-term debt, capital lease obligations, operating lease obligations, purchase obligations or long-term liabilities, other than an agreement to pay an affiliate of the Sponsor a monthly fee of $15,000 for office space, utilities and administrative support to the Company. We began incurring these fees on October 28, 2021. On January 28, 2023 this agreement was amended to provide that, rather than be payable on a monthly basis, the payments due thereunder commencing with the monthly payment payable on or about February 28, 2023 shall accrue and be payable on the completion of a business combination or the Company's liquidation.

The Underwriting Agreement with B. Riley Securities, Inc., provides that upon the consummation of our initial business combination, we will pay B. Riley Securities, Inc. out of the funds in the Trust Account a cash fee in an amount equal to 3.5% of the gross proceeds of the Public Offering (exclusive of any applicable finders' fees which might become payable). No fee will be due if we do not complete an initial business combination.

Critical Accounting Estimates

The preparation of the financial statements in conformity with US GAAP requires the Company's management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the balance sheet, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. One of the more significant accounting estimates included in these financial statements is the determination of the fair value of the warrant liabilities and the fair value of the non-redemptionagreements. Accordingly, the actual results could differ significantly from those estimates.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following critical accounting policy:

Common stock subject to possible redemption

The Company accounts for its shares of Class A common stock subject to possible redemption in accordance with the guidance enumerated in ASC 480 "Distinguishing Liabilities from Equity". Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company's control) are classified as temporary equity. At all other times, common stock is classified as stockholders' equity. The shares of the Company's Class A common stock feature certain redemption rights that are considered by the Company to be outside of the Company's control and subject to the occurrence of uncertain future events. Accordingly, at September 30, 2025 and December 31, 2024, the shares of Class A common stock subject to possible redemption in the amount of $6,249,923 and $8,646,368 are presented as temporary equity, outside of the stockholders' deficit section of the Company's balance sheets, respectively. The shares of Class A common stock that were issued upon conversion of shares of Class B common stock are not subject to redemption and accordingly are presented in the stockholders' deficit section of the Company's balance sheets.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, "Derivatives and Hedging." The Company's derivative instruments are recorded at fair value as of the closing date of the Initial Public Offering (November 2, 2021) and re-valuedat each reporting date, with changes in the fair value reported in the statements of operations. Derivative assets and liabilities are classified on the balance sheet as current or non-currentbased on whether or not net-cashsettlement or conversion of the instrument could be required within 12 months of the balance sheet date. The Company has determined the Public Warrants and the Private Placement Warrants are derivative instruments. As the Public Warrants and the Private Placement Warrants meet the definition of a derivative, the Public Warrants and the Private Placement Warrants are measured at fair value at issuance and at each reporting date in accordance with ASC 820, Fair Value Measurement, with changes in fair value recognized in the statement of operations in the period of change.

Warrants Instruments

We evaluated the Warrants in accordance with ASC 815-40,"Derivatives and Hedging-Contracts in Entity's Own Equity", and concluded that a provision in the Warrant Agreement related to certain tender or exchange offers as well as provisions that provided for potential changes to the settlement amounts dependent upon the characteristics of the holder of the warrant, precludes the Warrants from being accounted for as components of equity. As the Warrants meet the definition of a derivative as contemplated in ASC 815 and are not eligible for an exception from derivative accounting, the Warrants are recorded as derivative liabilities on the Balance Sheet. Upon consummation of the Initial Public Offering, the Company used a Monte Carlo simulation model to value the Public Warrants and a modified Black-Scholes model to value the Private Placement Warrants. The Company allocated the proceeds received from (i) the sale of Units (which is inclusive of one share of Class A common stock and one-halfof one Public Warrant), (ii) the sale of Private Placement Warrants, and (iii) the issuance of shares of Class B common stock, first to the warrants based on their fair values as determined at initial measurement, with the remaining proceeds allocated to shares of Class A common stock subject to possible redemption (temporary equity) and Class B common stock (permanent equity) based on their relative fair values at the initial measurement date. The Public Warrants and the Private Placement Warrants were classified within Level 3 of the fair value hierarchy at the measurement dates due to the use of unobservable inputs.

As of September 30, 2025 and December 31, 2024, the Public Warrants were valued using the publicly available price for the Warrant and are classified as Level 1 on the Fair Value Hierarchy. As of September 30, 2025 and December 31, 2024, the Company used a modified Black-Scholes model to value the Private Placement Warrants. The Company relied upon the implied volatility of the Public Warrants and the implied volatilities of comparable companies and the closing price as of September 30, 2025 and December 31, 2024, per Public Warrant, respectively, to estimate the volatility for the Private Placement Warrants. As of September 30, 2025 and December 31, 2024, the Private Placement Warrants were classified within Level 3 of the Fair Value Hierarchy at the measurement dates due to the use of unobservable inputs.

Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid to transfer of a liability, in an orderly transaction between market participants at the measurement date. US GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

Net loss per share

Net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period. The Company applies the two-classmethod in calculating earnings per share. Earnings and losses are shared pro rata between the two classes of shares. The calculation of diluted loss per share of common stock does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. As of September 30, 2025, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company. As a result, diluted net loss per common share is the same as basic net loss per common share for the period presented. As of September 30, 2025, the warrants are exercisable to purchase 19,500,000 shares of Class A common stock in the aggregate.

Recent accounting pronouncements

In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-09,"Improvements to Income Tax Disclosures" ("ASU 2023-09").The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in the ASU address investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09will be effective for us in the annual period beginning January 1, 2025, though early adoption is permitted. The Company has determined that ASU 2023-09 addresses disclosures only, and as such will not have any material effects on its financial condition, results of operation, or cash flows. The Company will adopt the standard beginning with our annual reporting for the year ending December 31, 2025.
