The complaint, Hatweek v. Fluence Energy, Inc., claims that the energy storage firm provided false guidance concerning its ability to fulfill backlogs and recognize revenue. Plaintiffs allege that the company’s projections relied on contract manufacturing facilities that were either incomplete, non-operational, or incapable of meeting the volume requirements promised to the market. Furthermore, the filing contends that corrective measures intended to resolve production issues at these sites failed to produce results.

Financial strain became apparent throughout 2026, punctuated by disappointing quarterly results and consecutive downward revisions to revenue and adjusted EBITDA guidance. The situation culminated on September 16, 2026, when the company slashed its full-year revenue outlook by approximately $600 million, citing delays in the ramp-up of contract manufacturing. Following the announcement, Fluence Energy stock fell 15.36% to close at $7.66 per share the following day. Law firm Kessler Topaz Meltzer & Check, LLP is currently inviting affected investors to discuss potential recovery options and the lead plaintiff process.
