The legal action, initiated by the firm Robbins LLP, covers individuals and entities who acquired FuelCell securities between June 4 and September 1, 2026. At the heart of the complaint is a capital equipment purchase agreement with Fit Energy USA LP for up to 380 megawatts of power. Plaintiffs allege the company failed to disclose that its production facilities were incapable of meeting the contract's required rates, leading to inflated overhead and significant financial charges.

The discrepancy surfaced publicly on September 2, 2026, when FuelCell reported a $45.3 million net loss for its fiscal third quarter. The company admitted that product costs and manufacturing overhead exceeded contractual pricing, forcing a $17 million charge. Following the disclosure, FuelCell shares dropped 15.69%, closing at $14.40. Investors who incurred losses during the class period must contact Robbins LLP by November 10, 2026, to be considered for the lead plaintiff position in the ongoing litigation.
