Kirby McInerney LLP is investigating potential federal securities-law claims and other alleged unlawful business practices involving FuelCell Energy, Inc. and members of its senior management. The investigation follows FuelCell's Sept. 2, 2026, Quarterly Report, which disclosed approximately $17 million in inventory and firm-purchase-commitment charges tied to the initial 30 MW phase of its Fit Energy agreement. The agreement, announced June 24, 2026, contemplates up to 380 MW of fuel cell systems across four phases. FuelCell said product costs and manufacturing overhead currently exceed the contractual pricing under the agreement. Its shares fell $2.68, or 15.7%, to close at $14.40 on Sept. 2. No lawsuit has been filed, and the investigation remains ongoing.
