Fluence Energy (FLNC) is down about 17% at $7.52, a few cents off its $7.01 52-week low, after cutting full-year guidance for the second time in six weeks. It fell 22% after hours on Wednesday.

The cut, in actual numbers

Fluence now expects FY2026 revenue of about $2.4bn, down from a prior midpoint of $3.0bn — $600m gone. Adjusted EBITDA goes from a roughly $10m loss to a $200m loss — a $190m swing in one press release.

It isn't demand. It's one building.

CEO Julian Nebreda said demand stayed strong at home and abroad and the international supply chain kept working. It pinned the revision on delays ramping up its contract manufacturing facility in Houston — the plant meant to carry US production.

Here's what the headline hides: Fluence's fiscal year ends 30 September (its last 10-K covered the year ended 30 September 2025). So $600m came out with roughly two weeks left in the year. That isn't a forecast being trimmed — batteries not built by mid-September can't ship and be recognised by month-end. The shortfall is already banked.

Analysts moved fast. Baird's Ben Kallo went to Underperform from Neutral and cut his target to $3 from $10. Goldman's Brian Lee went to Neutral from Buy at $9, writing that the extent of the production issues had been underestimated and flagging shipment-delay costs, cash flow and softer FY2027 revenue.

Who picks up what Fluence can't build

Grid-scale storage contracts are won on delivery dates. A utility with a 2027 interconnection slot that just watched a supplier miss its US ramp can move that order to Tesla's Megapack, built in Tesla's own plants — booked revenue moving between suppliers, not a mood swing. The same session said it twice: Generac jumped roughly 30% on a backup-generator deal with Amazon for data centres. Nobody is questioning power demand for the AI buildout — the question is who can actually build and deliver the hardware. See the day's other big movers.

The one thing that flips it

Fluence says its contract manufacturer has put corrective actions in place that lifted daily output, and the CFO called converting backlog into revenue and cash the top priority. The test is the FY2026 results call, where management promised its FY2027 plan — if Houston is running at rate by then, $2.4bn was the floor, not the first step down. Until then, watch whether the stock holds $7.01; a third cut is the scenario a $3 target assumes. Dates on the calendar.
