Law firm Bleichmar Fonti & Auld LLP announced on October 27, 2026 that a securities fraud class action lawsuit has been filed against Fluence Energy, Inc. and certain of its senior executives in the U.S. District Court for the Southern District of New York.

Key Highlights

  • Lead plaintiff deadline: Investors have until November 27, 2026 to ask the court to be appointed lead plaintiff.
  • Largest alleged stock drop: On February 5, 2026, Fluence's stock fell $10.04 per share, or 34.6%, from $28.99 to $18.95, according to the complaint.
  • Two additional drops alleged: The stock dropped 7.2% on August 6, 2026 (from $14.23 to $13.21) and 15.4% on September 17, 2026 (from $9.05 to $7.66), according to the complaint.
  • Legal claims: The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934.
  • Core allegation: Defendants allegedly 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," according to the complaint.

Alleged Misrepresentations and Stock Declines at Fluence Energy

According to the announcement from Bleichmar Fonti & Auld LLP, the complaint alleges that Fluence Energy, Inc. (NASDAQ:FLNC), 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, and assured investors it had contracted with multiple key production facilities to fulfill that demand.

The complaint alleges three separate adverse disclosures contributed to stock declines. On February 4, 2026, Fluence reported a net loss of $62.6 million and a GAAP gross profit margin of 4.9%, described as a 6.5% decline year over year, due to "additional estimated costs on two projects" located outside the U.S. On August 5, 2026, the company reported "weaker than expected revenue" and cut both revenue and adjusted EBITDA guidance, citing "production delays at new contract manufacturing facilities." On September 16, 2026, Fluence issued a mid-quarter guidance update and further reduced revenue and adjusted EBITDA guidance, attributing the cuts to "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 announcement constitutes attorney advertising, and the firm notes that past results do not guarantee future outcomes. The allegations in the complaint are unproven, and no court has made any finding of liability against Fluence Energy or its executives.
