As described in Item 5.07 of this Current Report on Form 8-K, on February 12, 2026, Plug Power Inc. (the “Company”) held a reconvened special meeting of stockholders (the “Special Meeting”), at which the Company’s stockholders approved an amendment (the “Charter Amendment”) to the Company’s amended and restated certificate of incorporation, as amended (the “Charter”), to increase the number of authorized shares of the Company’s common stock from 1,500,000,000 shares to 3,000,000,000 shares. The Charter Amendment became effective February 12, 2026 upon its filing with the Secretary of State of the State of Delaware.

The Charter Amendment is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference. The foregoing description of the Charter Amendment is qualified in its entirety by reference thereto.

Present at the Special Meeting, in person or by proxy, were holders of 769,385,735 shares of common stock of the Company as of December 12, 2025, representing at least one-third of the voting power of the outstanding shares of the Company’s common stock entitled to vote at the Special Meeting, which constituted a quorum. Holders of the Company’s common stock were entitled to one vote per share on each proposal.

The stockholders considered the following proposals at the Special Meeting and the final voting results are set forth below:

Proposal 1 - Amendment of the Company’s Charter to Adjust Voting Requirements to Align with Section 242(d)(2) of the Delaware General Corporation Law

Proposal 2 - Amendment of the Company’s Charter to Increase the Number of Authorized Shares of the Company’s Common Stock

At the Special Meeting, the stockholders approved Proposal 2 to amend the Charter to increase the number of authorized shares of the Company’s common stock from 1,500,000,000 shares to 3,000,000,000 shares. Proposal 1 did not receive the affirmative vote of a majority of the voting power of the shares of common stock outstanding and entitled to vote on the matter and therefore was not approved.

No other items were presented to the stockholders at the Special Meeting.
