Fluence's growth story hits a speed bump — but data center orders keep piling up
Record backlog and first hyperscaler awards collide with manufacturing ramp-up delays that force a guidance cut.

Record orders, a record backlog — and a guidance cut
Fluence Energy's fiscal third quarter was a study in contrasts. The company signed $1.44B of orders, nearly triple the prior-year figure, drove backlog to a record $6.4B, and booked its first data-center deals worth $850M — including a $300M behind-the-meter order from a developer and $550M of awards under a hyperscaler MSA. CEO Julian Nebreda opened the call with the headline: “we signed $1.44 billion of orders during the quarter, which is nearly triple the $509 million we signed in the same period last year.” — Julian Jose Marquez, President and Chief Executive Officer · 2026-08-06 That momentum is not incidental: data center customers now represent a fast-growing slice of a long-duration pipeline that reached 16 GWh, and the company expects fourth-quarter orders to set another record.
But the manufacturing engine sputtered. Two new contract manufacturing facilities — a fully automated enclosure plant in Houston and a Smartstack component plant in China — failed to reach full production in the quarter. Ahmed Pasha, CFO, conceded: “While our results this quarter were disappointing, the challenges we experienced were primarily related to construction and production start-up delays at new manufacturing capacity and scaling of our new products.” — Ahmed Pasha, Chief Financial Officer · 2026-08-06 The company cut its fiscal 2026 revenue midpoint to $3.0B (from $3.4B) and adjusted EBITDA to -$10M (from $50M), citing roughly $400M of revenue shifting into FY27 and $15M of costs tied to a planned battery supply agreement. Julian elaborated on the operational hiccups in Q&A:
the initial production had some quality — was not meeting our stringent testing, and we had to significantly delay production to ensure that we got the production in line with our quality.
The Houston plant, in particular, was delayed by construction and automation issues, with limited production only began this quarter; full output is not expected until fiscal Q1 2027. These production delays are a reminder that scaling a high-growth storage business is as much about contract manufacturer execution as about demand.
Data centers: from MSA to order
The data-center push is the company's clearest strategic shift. In the prior quarter, management highlighted two hyperscaler MSAs; now the company is converting that into signed orders. During the current call, Julian noted the developer deal closed in just three months from lead to order, versus a more typical 12-18 month cycle for utilities. He described the competitive win as rooted in product capability: “We win because of the density, safety and reliability of Smartstack as it combines with our operating systems that allows for very efficient load management and very, very good response times to the low voltage ride through.” — Julian Jose Marquez, President and Chief Executive Officer · 2026-08-06 That emphasis on operating system and technical differentiation is a recurring theme, but the speed of conversion is new. On the prior call (May 2026), Julian had said: “They are in a hurry, generally... I will say a lot faster than the conversion rate we have for our order from pipeline to orders and a lot faster on the conversion rate for orders to revenue, than what we do in our normal utility developer.” — Julian Jose Marquez, President and Chief Executive Officer · 2026-05-07 That forecast is now becoming concrete.
Still, the data-center revenue contribution is not yet visible in the income statement. The company maintains that revenue recognition follows project milestones, and backlog conversion will take time. Management is guiding 80-90% backlog coverage for FY27.
Financial implications
The push for scale is consuming cash. In the latest quarter, operating cash flow was -$121M, a sharp deterioration from the prior year’s positive flow, as the company built inventory ahead of deliveries. Total liquidity ended at ~$863M, roughly flat sequentially, and CFO Ahmed Pasha indicated that supporting the growing order book may require an additional $300-500M of working capital over the next year. The company nevertheless reaffirmed its expectation for ~$180M of annual recurring revenue by fiscal year-end.
That tension between growth ambition and short-term execution is what makes this report interesting. The stock has already digested the bad news — after a spring rally that took shares from below $10 to nearly $28, the last nine weeks have given back more than half, leaving the stock still ~70% below its IPO-era high. If the new facilities deliver as promised and data-center orders continue to compound, Fluence’s long-term story remains intact; if the production miss proves to be more than a one-quarter stumble, the backlog could start to weigh on confidence. For now, the order book is the bull case, and the factory floor is the bear case.
