**Item 1.01 Entry into a Material Definitive Agreement.**

On June 5, 2025, Plug Power Inc. (the "Company") entered into a Securities Purchase Agreement (the "Purchase Agreement") with Andrew J. Marsh, the Company's Chief Executive Officer (the "Purchaser"), pursuant to which it issued and sold one (1) share of the Company's newly designated Series F Mirroring Preferred Stock, par value $0.01 per share (the "Series F Mirroring Preferred Stock"), to such Purchaser for an aggregate purchase price of $1,000. The share of the Series F Mirroring Preferred Stock was issued for the sole limited purpose of obtaining the requisite vote of stockholders in connection with the proposal to amend the Company's charter to, at the discretion of the Company's Board of Directors (the "Board"), effect a reverse stock split with respect to the Company's common stock (the "Reverse Stock Split") at the next annual meeting of the Company's stockholders to be held on July 3, 2025 (the "2025 Annual Meeting"), as further described in Item 5.03 of this Current Report on Form 8-K.

The Purchase Agreement contains customary representations and warranties and agreements and obligations of the parties.

The foregoing description of the material terms of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, a copy of which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.

**Item 3.02 Unregistered Sales of Equity Securities.**

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

The share of Series F Mirroring Preferred Stock has not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or the securities laws of any state, and was offered and sold in reliance on the exemption from registration under the Securities Act afforded by Section 4(a)(2) thereof.

**Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.**

On June 5, 2025, the Company filed a Certificate of Designation of the Series F Mirroring Preferred Stock (the "Certificate of Designation") with the Secretary of State of the State of Delaware to create a new class of Series F Mirroring Preferred Stock. The Certificate of Designation designates one (1) share of authorized preferred stock as Series F Mirroring Preferred Stock.

The Certificate of Designation provides that the share of Series F Mirroring Preferred Stock will have 45,000,000,000 votes and will vote together with the outstanding shares of the Company's common stock as a single class exclusively with respect to the Reverse Stock Split proposal to be presented at the 2025 Annual Meeting.

The share of Series F Mirroring Preferred Stock will be voted, without action by the holder, on the Reverse Stock Split proposal in the same proportion as shares of common stock are voted on such proposal. The Series F Mirroring Preferred Stock will serve to reflect the voting preference of the holders of common stock that vote on the Reverse Stock Split proposal, whether for or against the proposal, and therefore will not override the stated preference of the holders of common stock who vote their shares for or against the proposal. As an example, if the holders of 50.5% of the common stock that vote at the 2025 Annual Meeting are voted for the Reverse Stock Split proposal, then 50.5% of the vote cast by the holder of the Series F Mirroring Preferred Stock shall be cast for the Reverse Stock Split proposal. The Series F Mirroring Preferred Stock otherwise has no other voting rights, including no right to vote in the election of the Company's directors. The Share of Series F Mirroring Preferred Stock is not convertible into, or exchangeable for, shares of any other class or series of stock or other securities of the Company.

The Company will redeem the Series F Mirroring Preferred Stock promptly following the approval or rejection of the Reverse Stock Split proposal by its stockholders. Upon such redemption, the Purchaser will receive consideration of $1,000 in cash.

The foregoing description of the Certificate of Designation does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Designation, a copy of which is filed herewith as Exhibit 3.1 and is incorporated herein by reference.

**Important Additional Information and Where to Find It**

As referenced above, the Reverse Stock Split proposal will need to be voted upon at the 2025 Annual Meeting and the Company filed a preliminary proxy statement with the Securities and Exchange Commission (the "Commission") on May 30, 2025, and intends to subsequently mail or otherwise make available a definitive proxy statement relating to, among other things, the Reverse Stock Split proposal. This communication does not contain all the information that should be considered concerning the Reverse Stock Split proposal, and is not intended to form the basis of any voting decision, investment decision or any other decision in respect of the Reverse Stock Split proposal. STOCKHOLDERS OF THE COMPANY ARE ADVISED TO READ THE PRELIMINARY PROXY STATEMENT AND ANY OTHER RELEVANT DOCUMENTS, INCLUDING THE DEFINITIVE PROXY STATEMENT (WHEN IT BECOMES AVAILABLE) THAT ARE FILED OR WILL BE FILED WITH THE COMMISSION IN CONNECTION WITH THE REVERSE STOCK SPLIT PROPOSAL, AS THESE MATERIALS WILL CONTAIN IMPORTANT INFORMATION ABOUT THE REVERSE STOCK SPLIT PROPOSAL AND OTHER PROPOSALS TO BE PRESENTED FOR VOTE AT THE 2025 ANNUAL MEETING. When available, the definitive proxy statement and other relevant materials will be sent or made available to stockholders of the Company as of June 9, 2025, the record date for the 2025 Annual Meeting. Stockholders will also be able to obtain copies of the preliminary proxy statement and the definitive proxy statement and other documents filed with the Commission, without charge, once available, at the Commission's website at www.sec.gov. Copies will also be available at no charge at the Company's website at https://www.ir.plugpower.com/financials/sec-filings/default.aspx.

**Participants in the Solicitation**

The Company and its directors and executive officers may be deemed participants in the solicitation of proxies from the Company's stockholders with respect to the matters to be presented for vote at the 2025 Annual Meeting, including the Reverse Stock Split proposal. A list of the names of those directors and executive officers and a description of their interests in the Company is contained in the Company's filings with the Commission, including in the Company's Annual Report on Form 10-K for the year ended December 31, 2024, as amended by Amendment No. 1 thereto on Form 10-K/A filed with the SEC on April 30, 2025, which was filed with the Commission and is available free of charge at the Commission's website at www.sec.gov, or on the Company's website at https://www.ir.plugpower.com/financials/secfilings/default.aspx. Additional information regarding the interests of such participants is contained in the preliminary proxy statement and will be contained in the definitive proxy statement for the matters to be presented for vote at the 2025 Annual Meeting, including the Reverse Stock Split, when available. In addition, we have engaged MacKenzie Partners, Inc. to assist in the solicitation of proxies.

Plug Power Inc. (the "**Company**"), a corporation incorporated and existing under the General Corporation Law of the State of Delaware (the "**DGCL**"), does hereby certify:

That pursuant to the authority expressly conferred upon the Board of Directors of the Company (the "**Board**") by the Company's Amended and Restated Certificate of Incorporation, as amended (the "**Certificate of Incorporation**"), and Section 151(g) of the DGCL, the Board on June 5, 2025 adopted the following resolution determining it desirable and in the best interests of the Company and its stockholders for the Company to create a series of the Company's preferred stock, par value $0.01 per share, designated as "**Series F Mirroring Preferred Stock**," none of which shares have been issued:

RESOLVED, that pursuant to the authority vested in the Board, in accordance with the provisions of the Certificate of Incorporation, a series of preferred stock, par value $0.01 per share, of the Company be and hereby is created, and that the designation and number of shares thereof and the voting and other powers, preferences and relative, participating, optional or other rights of the shares of such series and the qualifications, limitations and restrictions thereof are as follows:

**SERIES F MIRRORING PREFERRED STOCK**

The holder of the share of Series F Mirroring Preferred Stock, as such, shall not be entitled to receive dividends or other distributions of any kind.

The outstanding share of Series F Mirroring Preferred Stock shall have 45,000,000,000 votes, and shall vote together with the outstanding shares of the Company's common stock, par value $0.01 per share (the "**Common Stock**"), as a single class exclusively with respect to the Reverse Stock Split (as defined herein) and shall not be entitled to vote on any other matter. As used herein, the term "Reverse Stock Split" means any proposal to be presented at the next meeting of the Company's stockholders following the date of the filing of this Certificate of Designation with the Secretary of State of the State of Delaware to approve an amendment to the Certificate of Incorporation to effect a reclassification or combination of the issued shares of Common Stock into a smaller number of issued shares of Common Stock at a ratio specified in such amendment, together with any ancillary or administrative matters necessary or advisable in connection with such reclassification or combination.

For the avoidance of any doubt, but without limiting the foregoing, neither the merger, consolidation, conversion or domestication of the Company with or into any other entity, nor the sale, lease, exchange or other disposition of all or substantially all of the Company's assets shall, in and of itself, be deemed to constitute a Dissolution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Upon any Dissolution, the holder of the outstanding share of Series F Mirroring Preferred Stock shall be entitled to be paid out of the assets of the Company available for distribution to stockholders, prior and in preference to any distribution to the holders of Common Stock, an amount in cash equal to $0.01 for such outstanding share of Series F Mirroring Preferred Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <u>Redemption</u>.

As used herein, the "Redemption Time" shall mean the effective time of the Redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The consideration payable for the outstanding share of the Series F Mirroring Preferred Stock redeemed in the Redemption shall be an amount equal to $1,000 in cash (the "**Redemption Price**"), payable at the Redemption Time.

The share of Series F Mirroring Preferred Stock redeemed by the Company pursuant to this Certificate of Designation shall be automatically cancelled and shall no longer be outstanding..

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Severability</u>. If any provision of this Certificate of Designation is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Certificate of Designation so long as this Certificate of Designation as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).
