special meeting of stockholders financial

"On April 27, 2026, AltEnergy Acquisition Corp. ... held a special meeting of stockholders"

A special meeting of stockholders is an unscheduled gathering called to let shareholders vote on specific, often urgent company decisions—like mergers, major asset sales, changes to the board, or amendments to governing rules. Think of it as an emergency town hall where owners cast ballots in person or by mail/online; outcomes can materially change a company’s strategy, control or value, so investors pay close attention and may need to vote or adjust holdings accordingly.

Amended and Restated Certificate of Incorporation regulatory

"the proposal to file an amendment to the Company’s Amended and Restated Certificate of Incorporation"

A company’s amended and restated certificate of incorporation is an updated version of its foundational legal charter that replaces the older document and folds in all changes into one clear copy; it spells out corporate structure, classes of stock, shareholder rights and key governance rules. Investors care because it can change who controls the company, how votes are counted, what claims shareholders have on assets or dividends, and can introduce or remove protections against takeovers—like updating a house title after a major renovation to show who owns what and under what rules.

trust account financial

"a pro rata portion of the funds in the Company’s trust account"

A trust account is a special bank or brokerage account where assets are held and managed by a designated person or firm (the trustee) for the benefit of another person or group (the beneficiary). It matters to investors because it separates assets from personal or corporate funds, can protect assets, control how and when money is used, and may affect tax or legal rights—think of it as a locked drawer opened only under agreed rules.

redeem financial

"exercised their right to redeem such shares for a pro rata portion"

To redeem means to exchange a financial instrument—like a bond, preferred share, voucher, or convertible security—for cash or its agreed value when the issuer or holder triggers repayment. Investors care because redemption changes who holds the investment, when they get paid, and how much cash a company must use, affecting yield, ownership stakes and short‑term liquidity much like cashing a coupon or getting a loan repaid.

business combination financial

"to extend the date by which the Company must (1) consummate a ... business combination"

A business combination happens when two or more companies join together to operate as one, like two friends merging their teams into a single group. This is important because it can change how companies grow, compete, and make money, often making them bigger and more powerful in the market.

Submission of Matters to a Vote of Security Holders.

On April 27, 2026, AltEnergy Acquisition Corp., a Delaware corporation (the “Company”) held a special meeting of stockholders (the “Special Meeting”). As of March 20, 2026, the record date of the Special Meeting, there were 6,266,197 issued and outstanding shares of common stock of the Company, par value $0.0001 per share (the “Common Stock”) comprised of 6,016,197 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 Special Meeting, approximately 91.8% of the total shares of Common Stock outstanding as of the record date were present in person or by proxy, which constituted a quorum. A summary of the voting results at the Special Meeting for each of the proposals is set forth below.

Proposal 1

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 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 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 that was consummated on November 2, 2021 (the “IPO”), from May 1, 2026, to May 3, 2027 (the “Extended Date”) (such proposal, the “Extension”). The voting results for such proposal were as follows:


For	Against	Abstain
5,750,010	0	0

Proposal 2

The proposal to adjourn 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 were insufficient votes for, or otherwise in connection with, the approval of the Extension and the Redemption Limitation Amendment, was not presented at the Special Meeting as the Extension Proposal received a sufficient number of votes for approval.

On April 29, 2026, to effectuate the Extension, the Company filed an amendment to the Certificate of Incorporation (the “Amendment”) with the Secretary of State of the State of Delaware. The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by the terms of the Amendment, a copy of which is attached hereto as Exhibit 3.1 and incorporated herein by reference.

Stockholders holding 2,719 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, $32,970.61 (approximately $12.126 per share) will be removed from the Trust Account to pay such holders.
