Kirby McInerney LLP is investigating FuelCell Energy, Inc. and members of its senior management over possible violations of federal securities laws and other alleged unlawful business practices. The inquiry follows FuelCell’s September 2, 2026 Quarterly Report, which disclosed approximately $17 million in inventory and firm-purchase-commitment charges associated with the initial 30 MW phase of its Fit Energy agreement. Announced on June 24, 2026, the agreement covers 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, and its stock fell $2.68, or 15.7%, to close at $14.40 on September 2. No lawsuit has been filed, and the investigation remains ongoing to determine whether claims may be brought under federal securities laws. Investors who purchased or otherwise acquired FuelCell securities, or who have relevant information, may contact the firm at no cost. Kirby McInerney is a New York-based plaintiffs’ law firm focused on securities, antitrust, whistleblower and consumer litigation, and says shareholder recoveries from its securities work have totaled billions of dollars.
