Allegations Against Fluence Energy and the Stock Drops Described in the Complaint

According to the announcement by Bleichmar Fonti & Auld LLP, the complaint alleges that Fluence Energy, a provider of energy storage systems and optimization software, provided "record breaking fiscal year 2026 revenue guidance and significantly increased adjusted EBITDA guidance" based on its purported ability to capitalize on surging demand for data centers. The complaint further alleges that Fluence "assured investors that it had contracted with multiple key production facilities to fulfill demand." As alleged, defendants failed to disclose that several new contract manufacturing facilities "were not completed, not operational, and/or not capable of producing at the volumes Fluence's guidance provided."

The complaint describes three separate stock price declines. On February 5, 2026, shares fell 34.6% after Fluence reported a net loss of $62.6 million and a GAAP gross profit margin of 4.9%, attributing the results to "additional estimated costs on two projects" located outside the U.S. On August 6, 2026, the stock dropped $1.02 per share, or 7.2%, from $14.23 to $13.21, following a report of "weaker than expected revenue" and guidance cuts attributed to "production delays at new contract manufacturing facilities." On September 17, 2026, shares fell $1.39, or 15.4%, from $9.05 to $7.66, after Fluence issued a mid-quarter guidance update citing "delays in the ramp-up of our contract manufacturing facility."

The law firm states that all representation is on a contingency fee basis and that shareholders are not responsible for court costs or litigation expenses. The firm noted it will seek court approval for any potential fees and expenses. This announcement constitutes attorney advertising, and the firm states that "past results do not guarantee future outcomes."
