Plug Power announced Wednesday it has entered into a warrant inducement agreement that will bring in approximately $371 million in gross proceeds. The hydrogen solutions company disclosed the transaction in a filing with the Securities and Exchange Commission.

The deal involves an existing institutional investor who will immediately exercise outstanding warrants that were originally issued on March 20, 2025. These warrants cover 185,430,464 shares of common stock at an exercise price of $2.00 per share.
The investor will receive 31 million shares of common stock directly. The remaining shares will be delivered through pre-funded warrants to purchase up to 154,430,464 shares of common stock.
The pre-funded warrants carry a purchase price of $1.9999 per share. They can be exercised immediately for one share of common stock at just $0.0001 per share.
New Warrants Come With Higher Exercise Price
As part of the inducement agreement, Plug Power will issue new warrants to the investor. These new warrants allow the purchase of up to 185,430,464 shares of common stock.
The exercise price for the new warrants is set at $7.75 per share. This represents approximately a 100% premium over Plug Power’s closing stock price on October 7, 2025.
The new warrants won’t become exercisable right away. They require stockholder approval to increase the company’s authorized shares of common stock first.
Plug Power hasn’t reserved shares underlying the new warrants. The company doesn’t expect any exercises until it receives stockholder approval or effects a reverse stock split.
If Plug Power doesn’t increase its authorized shares by February 28, 2026, the new warrants may be cash settled. The new warrants will expire on March 20, 2028.
The transaction includes ownership limitations. The investor cannot own more than 4.99% of Plug Power’s outstanding common stock immediately after exercise, though they can elect to increase this to 9.99%.
Financial Details and Timeline
The gross proceeds of approximately $371 million will come before deducting estimated transaction expenses and fees. Plug Power plans to use the funds for working capital and general corporate purposes.
