FuelCell Energy, Inc. is registering for resale up to 12,000,000 shares of common stock issuable upon exercise of warrants held by FIT Energy USA LP under a shelf registration. These warrants are split into three tranches of 4,000,000 shares each, with an exercise price of $26.44 per share, subject to adjustment. Vesting is performance-based, tied to FIT’s non-refundable deposits under a Capital Equipment Purchase Agreement covering three project phases; any unvested warrants automatically terminate on June 22, 2028, and each vested tranche expires 24 months after its vesting date.
FuelCell Energy will not receive proceeds from any resale of shares by FIT, but will receive cash if and when the warrants are exercised. As of July 17, 2026, shares outstanding were 79,954,196, and FIT beneficially owned 13,216,025 shares; assuming full exercise and resale of the registered shares, FIT would own 1,216,025 shares, or 1.5% of the common stock.
