Fluence's AI power bet faces a securities-fraud suit after three guidance breaks and a 73% fall
A securities-fraud class action alleges Fluence's fiscal 2026 guidance rested on contract factories that were never ready, and the company's own disclosures back the timeline: three guidance breaks in eight months took the stock down about 73%.

Fluence Energy−1.93% — Fluence Energy, down 1.93 percent today, the Siemens-and-AES-backed grid-battery supplier selling into the AI power buildout, is now the subject of a federal securities-fraud suit that says its fiscal 2026 guidance was never deliverable 123. The complaint, Hatweek v. Fluence Energy, filed September 28, 2026, in the Southern District of New York, covers investors who bought between November 24, 2025, and September 16, 2026 123. Lead-plaintiff motions are due November 27 to 30 123.
The stock that carried the AI-storage bull case closed at €4.965 in Frankfurt on October 23, roughly a quarter of where it sat before February 4.
Demand was never the problem. Delivery was
The class-period story management told was demand acceleration: "accelerating data center growth, utility demand and rising industrial loads," with backlog "securing" or "covering" fiscal 2026 revenue 16. The complaint's story is different: the revenue depended on new contract-manufacturing facilities that were not completed, not operational, or incapable of producing at the volumes the guidance assumed, and the corrective measures were not working 13. Hagens Berman's notice adds the detail that stings: the Houston facility's automated welding failed, so workers welded by hand 6.
The receipts, three breaks in eight months
On February 4, 2026, Fluence reported a 4.9% GAAP gross margin, down 6.5 points year over year, and a net loss of $62.6 million against $57.0 million a year earlier 1. The stock fell 34.63% the next day, to $18.95 1.
On August 5, third-quarter revenue of $649.8 million came in "weaker than expected," adjusted gross margin hit 5.9% against 15.4% a year earlier, and $400 million of deliveries slid into fiscal 2027 12. The stock closed at $13.21 12. Then, on September 16, a mid-quarter update cut the full-year revenue guide by about $600 million to $2.4 billion and swung the adjusted EBITDA guide from a $10 million loss to a $200 million loss, blamed on "delays in the ramp up of our contract manufacturing facility in Houston 156." Shares closed at $7.66 the next day, and roughly $3 billion of market value is gone since February, per Hagens Berman 156.

The counterpoint, and what to watch
The bull case survives on paper: Fluence's own September release says demand "remained strong both domestically and internationally" and that the contract manufacturer's corrective actions "have already yielded an increase in daily production levels" 5. If the factories ramp, the backlog converts and the lawsuits are noise. But delivery failed three times in eight months, and an order book does not fix a factory.
CFO Ahmed Pasha has promised fiscal 2027 plans "to generate neutral to positive operating cash flow... without external capital" when fiscal 2026 results land 5. That report, and whether the $2.4 billion guide holds, is the reading that decides which story was true 5.
