Fluence Energy shares fell $1.39, or 15.36%, to $7.66 on September 17, 2026, after the company cut its full-year revenue forecast by approximately $0.5 billion to a midpoint of $2.4 billion and reduced its EBITDA outlook from negative $10 million to negative $200 million. Fluence attributed the changes to continuing delays in ramping up its contract manufacturing facility in Houston. Bragar Eagel & Squire, P.C. is investigating potential federal securities-law violations and other unlawful business practices, and is seeking investors, long-term stockholders and others with relevant information. The update follows an earlier Hagens Berman investigation into Fluence’s Houston facility disclosures, including reported problems with customized automated welding, final assembly and U.S. production. Existing materials describe the guidance revision as occurring on September 16 and quantify it as a further $600 million, or 20%, revenue reduction, creating a date and amount discrepancy with Bragar Eagel & Squire’s September 17 account. The facility produces thermal management systems for Fluence’s Gridstack Pro battery energy storage solutions and was developed with Bergstrom Inc.
