Fluence Energy, Inc. faces securities class-action claims and related investigations alleging that the company and certain officers or directors misled investors about its backlog, contract manufacturing facilities, project deliveries, revenue recognition and ability to benefit from rising data-center demand. The claims follow disclosures of margin compression, higher project costs, manufacturing delays, rising losses and successive reductions to fiscal 2026 guidance. Fluence shares fell $21.33, or about 73%, from the February 4 disclosure through September 17, 2026, wiping out roughly $3 billion in market capitalization, according to Hagens Berman. The firms announced different lead-plaintiff deadlines: November 30, 2026, in Pomerantz's announcement and November 27, 2026, in Hagens Berman's announcement.
