Bloom Energy (BE) Q3 2026 earnings review
Bloom Energy raises its sales plan, but cash turns negative
Bloom Energy, a maker of fuel cells that generate onsite power, lifted revenue and profit while burning cash. Sales more than doubled to $1.24 billion, and finance chief Simon Edwards raised the full-year outlook for a third time. By our math, the new plan points to $1.45 billion of fourth-quarter revenue, even as unbilled work and factory spending pushed free cash flow to minus $181 million.
| Revenue | $1,235.8M +138.1% from a year ago |
|---|---|
| Operating margin, excluding one-offs | 23.1% +14.2 percentage points from a year ago |
| Free cash flow (by our math) | -$180.6M +$174.8M last quarter |
| Full-year revenue outlook | Raised $450M middle of the range: 122% growth |
⚖️ Verdict: 🟢 Bullish
The story got better because $309 million of new customer deposits and a third outlook raise show that data-center power orders are still accelerating. Operating margin excluding one-offs also reached 23% as overhead costs shrank as a share of sales. The bad news: unbilled contract assets doubled to $859 million, draining cash, and the release gave no update on customer concentration.
The question now is whether the surge in unbilled contract assets and customer deposits reflects broad customer demand or payment timing on a couple of giant data-center projects. Either fourth-quarter billings convert that $859 million balance into cash, or working capital keeps absorbing the company's reported profits. The quarterly filing's concentration note and fourth-quarter cash flow will settle it.
🐂 Bull Case
Upfront Customer Deposits Jumped by $309 Million
Bloom Energy makes solid-oxide fuel cells that generate electricity on site for data centers and factories. Because the company stopped publishing its order backlog this year, the best forward indicator on its balance sheet is deferred revenue and customer deposits — cash that buyers pay upfront when they sign new contracts.
That balance jumped by $309.3 million this quarter to $754.4 million, more than eight times its level a year ago. Product revenue rose 179.4% from a year ago to $1,073.6 million as the US company booked and shipped orders inside the same year. Finance chief Simon Edwards cited year-to-date performance and demand to "raise our 2026 outlook for the third time this year".
This matters because the deposit surge shows customers are still signing near-term delivery agreements ahead of the fourth quarter. By our math, the new full-year plan points to $1,447.7 million of fourth-quarter sales at the middle of the range, up 17.1% from this quarter.
What to watch: the customer deposit split in Note 3 of the quarterly filing when it arrives. A rising deposit balance would confirm that contracted deliveries back the fourth-quarter step-up.
Overhead Discipline Lifted the Operating Margin
Bloom's profit argument rests on keeping engineering and corporate overhead steady while fuel-cell shipments multiply. Total revenue grew 138.1% from a year ago to $1,235.8 million, while operating expenses excluding one-offs grew 26.2% to $140.5 million.
- Operating margin excluding one-offs: 23.1%, up 14.2 percentage points from a year ago
- Research and development (engineering costs): 5.2% of revenue, down 4.2 percentage points by our math
- General and administrative (corporate overhead): 6.1% of revenue, down 4.2 percentage points by our math
- Sales and marketing: 4.2% of revenue, down 3.9 percentage points by our math
Because revenue grew more than five times faster than overhead, operating income excluding one-offs reached $285.7 million, up from $46.2 million a year ago. The fuel-cell maker also lowered its full-year target for operating expenses excluding one-offs to 12% of sales, down from 13% last quarter and 19% in 2025.
What to watch: fourth-quarter operating expenses excluding one-offs against the implied 23.5% operating margin. Holding overhead near current levels would prove the cost structure scales without extra hiring.
Service Margins Held Above 20% Again
Every fuel-cell server Bloom ships comes with a multi-year maintenance contract, and the company wants this service business to become a steady profit stream. For years, replacing fuel-cell units ate up those profits. This quarter, service gross margin excluding one-offs reached 21.4%, up 7.0 percentage points from a year ago and above 20% for a second straight quarter.
Product gross margin excluding one-offs also rose 2.5 percentage points from a year ago to 38.4%, lifting total gross margin excluding one-offs by 4.1 percentage points to 34.5%. That strength covered a loss in installation, where gross margin excluding one-offs fell 13.5 percentage points to minus 3.5%. Accrued warranty liabilities on the balance sheet also ticked down to $70.3 million from $77.8 million in June.
What to watch: the warranty reserve footnote in the quarterly filing. Stable specific warranty charges would show that older fleet repairs are not undermining the 21.4% service margin.
🐻 Bear Case
Unbilled Work and Factory Spending Drained Cash
"We continue to invest with discipline to build the capabilities and capacity needed to scale the business," finance chief Simon Edwards said. Last quarter the company generated $226.4 million of operating cash flow and pointed to a full-year baseline above $375 million. This quarter, cash moved the other way even as reported profit hit a record.
- Operating cash flow: minus $27.1 million, down from positive $226.4 million last quarter
- Free cash flow: minus $180.6 million by our math, down from positive $174.8 million last quarter
- Contract assets (revenue booked before billing the customer): $858.6 million, up 100.5% from June by our math
- Capital spending on factories and equipment: $153.5 million, nearly triple last quarter's $51.6 million
Operating cash turned negative because Bloom booked $430.3 million of revenue into unbilled contract assets and added $175.2 million to unpaid customer bills. That means the power-equipment maker recognized sales on paper much faster than it billed or collected cash, cutting year-to-date operating cash flow to $272.9 million.
What to watch: contract assets and operating cash flow in the fourth quarter. A drop in contract assets must turn into cash collections to hit the $375 million full-year cash flow baseline.
Risks This Quarter Didn't Answer
Chief executive KR Sridhar said "What began with hyperscalers is rapidly moving across market segments because every business needs reliable power to grow." However, the press release and presentation omitted the numbers needed to test that claim and five other standing concerns.
- Customer concentration (one buyer was 73% of first-half sales): not in the release; Note 1 of the quarterly filing will show third-quarter shares.
- Sales to partly owned Brookfield joint ventures: not in the release, though deferred profit on them rose to $20.1 million; the filing will disclose related-party revenue.
- Scandium supply and new import tariffs: not mentioned; the filing's supply-chain and tariff-receivable notes will update both.
- Product backlog and AI data-center site delays: undisclosed since early 2026; fourth-quarter remarks will show whether annual backlog reporting returns.
- Factory capacity and financing commitments: no gigawatt or Brookfield shelf update; year-end remarks test the 2-gigawatt target.
💲 Other KPIs
Inventories — raw materials and fuel-cell parts on hand — rose 22.4% from last quarter, up from a 3.5% increase in the second quarter. Building this stock used $170.4 million of cash in the quarter, compared with $26.5 million in the prior period, as Bloom stocked components ahead of fourth-quarter deliveries.
The diluted share count used for profit per share excluding one-offs rose 3.8% from a year ago and 0.3% from last quarter. Basic shares rose 25.5% from a year ago to 294.8 million because debt holders converted green notes into common stock during the first half of the year.
🔮 Guidance
Raised. The middle of the range moved up $450 million to $4.5 billion, or 122% growth for the year. By our math, that leaves $1,447.7 million for the fourth quarter, up 86.2% from a year ago against a tougher comparison base and up 17.1% from this quarter. It is the third raise this year: +$400M, +$450M, +$450M.
Unchanged. The full-year plan still calls for a gross margin excluding one-offs of about 34%, up 3.7 percentage points from 2025. By our math, after running below 34% in the first half and at 34.5% in the third quarter, hitting the full-year target requires about 34.7% in the fourth quarter.
Raised. Management lifted the middle of the range by $145 million to $995 million, or four-and-a-half times last year's profit. By our math, that implies $340.0 million in the fourth quarter, a 23.5% margin. It is the third raise this year, and each addition is slightly smaller: +$225M, +$175M, +$145M.
Raised. The middle of the range rose $0.55 to $3.25 per share, more than four times the $0.76 earned in 2025. By our math, the outlook leaves $1.09 per share for the fourth quarter, up from $0.94 this quarter. This is the third raise this year: +$0.65, +$0.65, +$0.55.
Raised (cost ratio lowered). The supplemental presentation tightened the full-year overhead target to 12% of revenue at the middle of the sales range, down from 13% last quarter, 15% in the first quarter, and 19% in 2025. Faster sales growth is spreading fixed engineering and administrative costs over a wider base.
❓ Key Questions
Why Did Unbilled Contract Assets Double to $859 Million?
Contract assets rose by $430.3 million this quarter, more than a third of reported revenue, and pushed operating cash flow into negative territory. Investors need to know which milestone delays kept Bloom from billing those customers and when the cash will arrive.
Does the $375 Million Operating Cash Flow Baseline Still Stand?
Last quarter management pointed to $375 million-plus of full-year operating cash flow as 100% of operating profit raises dropped to cash. This quarter operating income rose again, but operating cash flow was minus $27.1 million and the release gave no cash flow target.
Did One Customer Still Drive Most of Third-Quarter Revenue?
One customer accounted for 73% of first-half revenue, and two buyers made up 65% of second-quarter sales. Chief executive KR Sridhar said demand is spreading across industries, a claim only the concentration table in the quarterly filing can verify.
How Much Revenue Came From Brookfield Joint Ventures?
In the first half, Bloom booked $376.1 million of related-party revenue by selling fuel cells to financing vehicles it partly owns. The press release does not say how much of this quarter's $1,073.6 million in product sales went to those affiliates.
Where Did the $153 Million CapEx Jump Go?
Capital spending nearly tripled from last quarter to $153.5 million, yet management stopped giving gigawatt figures for its factory capacity in August. Investors need to know how much production capacity this spending added.
