Insights

Corporate Securities Counsel

TL;DR: The filing documents warrant instruments and a counsel opinion, focusing on legal mechanics rather than economic terms.

The exhibits list a Warrant Inducement Agreement and two warrant forms plus an opinion and consent from counsel, which indicates the company has prepared the legal framework to issue warrants.

Because no pricing, quantities, counterparties, or settlement mechanics are provided, the legal readiness is clear but the economic impact is undefined; monitor subsequent disclosures for the actual issuance terms and any shareholder approvals.

Investor Relations Analyst

TL;DR: This is a disclosure of contractual and legal documents, not a disclosure of material economic terms.

The filing attaches forms and counsel opinion, which helps investors locate the exact contractual language once reviewed. These exhibits allow stakeholders to assess exercise mechanics, registration rights, and transferability when the terms are later provided.

Absent stated amounts or prices, the next material items to watch are any follow-up filings that attach executed agreements or disclose issuance size and dilution metrics within a short-term timeframe.

Item 1.01 Entry Into a Material Definitive Agreement.

On October 8, 2025, Plug Power Inc. (the “Company”) entered into a letter agreement (the “Warrant Inducement Agreement”) with the holder (the “Investor”) of warrants issued on March 20, 2025 (the “Existing Warrants”), whereby in consideration for exercising in full for cash all of the Existing Warrants held by the Investor at the exercise price as set forth in the Existing Warrants of $2.00 per share, the Company agreed to (i) amend the Existing Warrants to provide for the issuance of Pre-funded Warrants (the “Pre-funded Warrants”), at the option of the Investor, if, as a result of the exercise of the Existing Warrants, the Investor’s beneficial ownership of shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), would exceed such Investor’s beneficial ownership blocker election as set forth in the Existing Warrants immediately following such exercise, and (ii) issue new warrants to the Investor (the “New Warrants” and together with the Pre-funded Warrants, the “Warrants”) to purchase up to 185,430,464 shares of Common Stock (the “Transaction”).

The Transaction was made pursuant to a prospectus supplement dated October 8, 2025 and an accompanying base prospectus that forms a part of the Company’s registration statement on Form S-3 (File No. 333- 287577), which was filed by the Company with the Securities and Exchange Commission (the “SEC”) on May 27, 2025 and declared automatically declared effective by the SEC. The Transaction is expected to close on or about October 9, 2025, subject to customary closing conditions.

The purchase price of each Pre-funded Warrant will be equal to the exercise price of $2.00 per Share, minus $0.0001. Each Pre-funded Warrant will be immediately exercisable for one share of Common Stock at $0.0001 per share (subject to applicable adjustment in the event of certain share dividends and distributions, share splits, share combinations, reclassifications or similar events affecting the Common Stock) and expire on March 20, 2028.

The New Warrants will entitle the Investor to purchase up to 185,430,464 shares of Common Stock at $7.75 per share (subject to applicable adjustment in the event of certain share dividends and distributions, share splits, share combinations, reclassifications or similar events affecting the Common Stock) and expire on March 20, 2028. The New Warrants will not become exercisable for shares unless and until the Company takes all action necessary to increase its authorized shares of Common Stock to an amount sufficient to provide for the issuance of shares upon the exercise of the New Warrants. The New Warrants will be cash settled after February 28, 2026 if the Company has not increased its authorized shares of Common Stock.

The gross proceeds from the Transaction, before deducting estimated transaction expenses and fees, is expected to be approximately $371.0 million. If the New Warrants are fully exercised on a cash basis, the Company will receive an additional $1.4 billion in gross proceeds. No assurance can be given that any of the New Warrants will be exercised. The Company intends to use the net proceeds from the Transaction for working capital and general corporate purposes.

Each New Warrant or Pre-Funded Warrant will be exercisable solely by means of a cash exercise, except that a New Warrant or Pre-Funded Warrant will be exercisable via cashless exercise if at the time of exercise, a registration statement registering the issuance of the shares of Common Stock underlying the New Warrants and Pre-Funded Warrants (the “Warrant Shares”) under the Securities Act of 1933, as amended (the “Securities Act”), is not then effective or the prospectus contained therein is not available for the issuance of the Warrant Shares. The New Warrants and Pre-Funded Warrants will include certain rights upon “fundamental transactions” as described in the New Warrants and Pre-Funded Warrants, including the right of the Investor thereof to receive from the Company or a successor entity the same type or form of consideration (and in the same proportion) that is being offered and paid to the holders of Common Stock in such fundamental transaction with respect to the unexercised portion of the applicable New Warrants or Pre-Funded Warrants immediately prior to such fundamental transaction. Alternatively, the holder of a New Warrant shall have the right to receive the cash value of the remaining unexercised portion of its New Warrants upon a fundamental transaction, such value to be calculated using the Black-Scholes Option Pricing Model, as described in the New Warrants. A holder of the New Warrants or Pre-Funded Warrants (together with its affiliates) may not exercise any portion of a New Warrant or Pre-Funded Warrant to the extent that the holder would beneficially own more than 4.99% (or, as may be increased upon written notice at the election of the holder, up to 9.99%) of the Company’s outstanding Common Stock immediately after exercise.
