Plug Power Inc. entered a Release Event License Agreement with Walmart Inc. covering escrowed GenKey System software and related materials that Walmart may use for internal maintenance only if specified “Release Events” occur. Walmart will pay an initial license fee at escrow confirmation and an annual license fee, with higher annual and one-time fees if a Release Event happens. The agreement runs for 15 years, includes mutual indemnification, and outlines efforts to identify alternative stack suppliers with limited conditional stack-sourcing rights for Walmart.
Pursuant to the agreement, Walmart irrevocably terminated a prior transaction agreement and forfeited all vested portions of a warrant to purchase Plug Power common stock, and all unvested portions were cancelled, so no shares will be issuable under that warrant, eliminating potential future dilution of up to 42,192,479 shares. As of the effective date, 34,554,185 shares under the warrant had vested and 7,638,294 shares remained unvested.

Plug Power Inc. has called a virtual special meeting on January 29, 2026 for stockholders to vote on three charter changes. Proposal 1 would lower the voting threshold for certain future amendments, such as changes to authorized shares or reverse stock splits, to match Delaware’s Section 242(d)(2), so approval would be based on a majority of votes cast rather than a majority of all shares outstanding.
Proposal 2 would double authorized common stock from 1.5 billion to 3.0 billion shares. The company says it has less than 0.4% of authorized common stock left and must increase authorized shares by February 28, 2026 to honor warrants for 185,430,464 shares and $375.0 million of 6.75% convertible notes due 2033. If Proposal 2 fails, the board plans to use a previously approved reverse stock split instead. Proposal 3 would allow adjournment of the meeting to gather more proxies. The board unanimously recommends voting in favor of all three proposals.
