About the Fluence Energy class action lawsuit

A securities class action has been filed against Fluence Energy, Inc. (NASDAQ: FLNC), an energy storage company, and certain of its executives on behalf of investors who purchased or otherwise acquired Fluence Energy securities between November 24, 2025 and September 16, 2026 (the “Class Period”). The case, Hatweek v. Fluence Energy, Inc., No. 1:26-cv-08475, was filed on September 28, 2026 in the U.S. District Court for the Southern District of New York.

Investors who want to ask the court to appoint them lead plaintiff must do so by November 30, 2026. If you invested in Fluence Energy during the Class Period and lost money, contact Kaplan Fox using the form on this page, by emailing pmayer@kaplanfox.com, or by calling (646) 315-9003.

What the lawsuit alleges

The complaint alleges that, throughout the Class Period, the defendants made false and/or misleading statements and/or failed to disclose that:

• Fluence Energy’s ability to deliver on its backlog, and to recognize the revenue underlying its fiscal 2026 guidance, depended on new contract manufacturing facilities that were not completed, not operational, and/or not capable of producing at the volumes the guidance assumed;
• the corrective measures the company had put in place to address production problems at its contract manufacturers were not fixing those problems; and
• as a result, the company was unlikely to deliver its backlog as promised, and the defendants’ positive statements about the business lacked a reasonable basis.

What happened to Fluence Energy stock

According to the complaint, the truth emerged through a series of disclosures:

• February 4, 2026. Fluence Energy reported first quarter 2026 results, including a GAAP profit margin of approximately 4.9%, down 6.5 percentage points from a year earlier, which it attributed to “additional estimated costs on two projects.” The stock fell $10.04 per share, nearly 35%, to close at $18.95 on February 5, 2026.
• End of the Class Period. After the company sharply cut its full-year adjusted EBITDA guidance, the stock fell $1.39 per share, or 15.36%, to close at $7.66 on September 17, 2026.

Who may be eligible

The proposed class includes investors who purchased or otherwise acquired Fluence Energy securities between November 24, 2025 and September 16, 2026. If you bought during that period and lost money, you may be a member of the class.
