The backlog amount, $5.6 billion as of the second quarter of fiscal 2026, covered by orders already in hand, would make most industrial companies jealous, according to a conference room at Fluence Energy’s Arlington, Virginia headquarters. The management team has reaffirmed guidance that suggests continued revenue growth through the second half of the year. Hyperscale AI data center operators were identified as the most commercially significant new customer segment in the company’s five-year history during the Q2 results call on May 7, 2026.
Particularly mentioned as the growth category boosting trust were master service agreements with data center developers. Five days later, 20 million shares were sold in a secondary offering by the current controlling stockholders. The stock dropped 16.3%. FLNC is currently trading at $22.53 on June 6, which is about 33% less than its February 52-week high of $33.51.
Any honest analysis of FLNC must start with the 52-week range of $4.64 to $33.51 since it tells nearly the whole narrative of how the market has interpreted Fluence. The stock was pricing in execution failure at the August 2025 low following a large guidance drop that coincided with underwhelming Q3 FY2025 data. In fiscal year 2025, the company’s sales was $2.3 billion, a decrease from $2.7 billion in fiscal year 2024. Despite rising margins, GAAP profitability remained elusive. Then the story changed.
Revenue for Q1 FY2026, which was released in February 2026, was $475.2 million, a 154 percent increase over the previous year. MSA contracts for data centers began to show up in the backlog. The price of the shares reached $33.51. In May, the momentum was broken by the secondary offering. In the meantime, the company’s actual business has been expanding, and its guidance backlog has been hitting all-time highs. The attitude of the investors who own it has changed, not the firm itself.
The aspect of the Fluence tale that was incomplete at the time of the company’s 2021 IPO was the AI infrastructure connectivity. The main purpose of battery energy storage devices, which Fluence manufactures and uses under product names like Gridstack Pro and Ultrastack, was to stabilize the grid for renewable energy. When a solar farm generates more energy than the grid can handle at noon, storage systems store the extra energy and release it when demand increases. It’s a big and expanding application. AI data center applications, however, fall into a distinct category.
The power grid in many high-growth data center markets, such as Virginia, Texas, Arizona, and portions of the Southeast, is so overburdened that direct battery storage installations are turning into practical requirements rather than optional features. Hyperscale facilities require dependable, dispatchable backup power at scale. In late 2025, Fluence provided a 1,200 MWh project for a storage facility in Arizona for BrightNight and Cordelio Power. These kinds of projects form the basis of the $5.6 billion backlog.
For the next year or two, the stock is likely to be plagued by the GAAP profitability issue. The figures show that the net loss in Q2 2026 was $20.9 million, a considerable reduction above the $54 million loss in Q2 2025. The Q2 2026 adjusted gross margin of 11.1% indicates a company that is making a profit while yet incurring large expenses. Continued improvement is implied by the company’s guidance.
UBS’s Sell rating and RBC’s more cautious target effectively raise doubts about whether that improvement would materialize on the timeline suggested by the guidance. The market appears to settle in the middle. Following the Q2 results, Citi increased its target to $26, which is essentially where the company was trading at the time. This is about as neutral a call as an analyst can make.

When investors watch FLNC in June 2026, they are essentially evaluating two things at once: how quickly data center MSA revenue moves from backlog to recognized revenue and whether the gross margin can keep rising to levels that would support the GAAP path to profitability.
Observing the difference between the $5.6 billion backlog and the $4.22 billion market cap gives the impression that the market is still not quite persuaded that the backlog is as long-lasting and high-margin as management claims. Whether this is a delay in recognition or justified skepticism is still up for debate. It will likely be addressed in the following two or three earnings releases.
