Plug Power is issuing warrants and pre-funded warrants tied to previously issued March 20, 2025 warrants in exchange for full exercise of those March Warrants at $2.00 per share. The offering includes 185,430,464 new warrants exercisable at $7.75 (expire March 20, 2028) and 154,430,464 pre-funded warrants exercisable at $0.0001 (expire March 20, 2028), together covering up to 185,430,464 shares issuable on exercise of the new warrants and 154,430,464 pre-funded shares. Net proceeds from the initial exercises (March Warrants into shares and pre-funded warrants) are estimated at $354 million, excluding potential additional proceeds of approximately $1.4 billion if all new warrants and pre-funded warrants are later exercised for cash. New warrants are not exercisable for shares until the company obtains stockholder approval or effects a reverse stock split to increase authorized shares; absent that, the new warrants may be cash-settled after February 28, 2026. The new and pre-funded warrants will not be listed and likely will have limited liquidity. Financial advisors receive a fee equal to 4.25% of gross proceeds from the exercised March Warrants. The common stock trades under the symbol PLUG ($3.87 last reported on October 7, 2025), and total shares outstanding post-offering are estimated at 1,231,696,599 assuming no exercise of the new instruments.
