Fluence Energy shareholders faced a 15% share-price decline on September 17, 2026, after management disclosed further problems at its Houston, Texas, supply-chain facility and said the company had fired its Chief Product Officer on September 11. Hagens Berman opened an investigation into whether Fluence was sufficiently transparent about the facility’s operational readiness and related financial effects, and whether federal securities laws may have been violated. The disclosures followed a further $600 million, or 20%, reduction in 2026 revenue guidance, with management saying more than 80% of the expected decrease was tied to U.S. production issues. Fluence also reported continuing problems with the facility’s customized automated welding process, slower-than-expected final assembly and a shift to manual welding. The developments followed earlier guidance reductions, analyst downgrades and price-target cuts. Fluence had previously reported approximately $2.4 billion of fiscal 2026 revenue guidance, versus Wall Street expectations of roughly $2.96 billion, an adjusted EBITDA loss forecast of approximately $200 million, $1.44 billion in quarterly orders and a record $6.4 billion backlog. Levi & Korsinsky, LLP separately said it was investigating potential securities law violations involving Fluence’s disclosures.
