Plug Power (PLUG) Q3 2026 earnings review
Plug Power sales rise 13%, but asset sales fund cash
Plug Power, a maker of hydrogen fuel cells and electrolyzers, grew sales and slowed its cash drain, but one-off gains carried the bottom line. Revenue rose 13% from a year ago as forklift fuel cell deployments more than doubled, and upfront customer deposits grew again. Chief executive Jose Luis Crespo kept the full-year sales outlook, which by our math requires a 38% revenue jump from the third quarter into the fourth. However, the reported profit came from non-cash accounting gains on debt and warrants, while gross margin slipped from last quarter.
| Revenue | $200.6M +13.3% from a year ago |
|---|---|
| Gross margin | -2.7% -0.9% last quarter (-67.9% a year ago) |
| Net cash usage | $28M $61M last quarter |
| Full-year revenue outlook | Unchanged 15%–16% growth (implies +23% in Q4) |
⚖️ Verdict: ⚪ Neutral
The story is unchanged because new electrolyzer orders and lower overhead offset a step back in gross margin and a cash figure flatter than core operations. A 29% rebound in deferred revenue eases the concern that the order book was shrinking. The caution: by our math, everyday operations and capital spending still burned $91 million in cash, and the company reached its $28 million net cash usage figure by selling $40 million of property and releasing $41 million from restricted escrow accounts.
The question now is whether fourth-quarter equipment shipments can lift gross margin enough to reach the year-end cash profit target without leaning on new share sales. Either the backlog converts into a year-end shipping surge that covers overhead, or a shortfall forces the company to tap its newly doubled 3 billion authorized share count. Fourth-quarter revenue and operating cash flow will settle it.
🐂 Bull Case
Deferred Revenue Rebounded as Electrolyzer Deals Signed
Plug Power makes GenEco electrolyzers, machines that use electricity to split water into hydrogen fuel. Management says European clean-energy rules called RED III are driving demand as the company is "converting commercial opportunities into projects across sustainable fuels, ammonia production, and industrial hydrogen applications". In the first half of the year, deferred revenue — cash customers pay upfront for orders not yet delivered — shrank by $14.5 million, raising concern that new orders were drying up.
That balance grew again in the third quarter. By our math, total deferred revenue rose $25.1 million from the second quarter, or 29.1%, to $111.6 million. The hydrogen company signed an agreement with Arcadia eFuels to supply 280 megawatts of electrolyzers for aviation fuel in Denmark, and finalized a 50-megawatt order with Orica in Australia. Because customers pay deposits when projects move forward, the rising balance shows new contracts are finally bringing in cash before shipment.
What to watch: the quarterly filing's breakdown of electrolyzer revenue and total remaining performance obligations, the value of all booked contracts. A rise above $669 million would confirm these awards are rebuilding the multi-year order book.
Forklift Fuel Cell Deployments More Than Doubled
Plug Power's oldest business sells GenDrive fuel cells, which replace batteries in warehouse forklifts for large retailers like Amazon and Walmart, alongside maintenance contracts. The company is developing next-generation units designed to "improve efficiency, extend stack life, and increase reliability" as those major customers refresh more than 20,000 units over three years.
The company deployed 1,136 GenDrive units in the third quarter, up 110% from 540 units a year ago, though down 32% from 1,666 units in the second quarter. More reliable units allowed each technician to handle more forklifts. Service revenue jumped 47.0% from a year ago to $29.0 million, and service gross margin before accounting reserve releases reached 30.5%, up from 27.2% last quarter.
What to watch: fourth-quarter GenDrive unit deployments. A rebound above second-quarter levels is needed to deliver the year-end equipment sales spike.
Fuel and Power Agreement Losses Narrowed Again
For years, Plug Power lost money on every kilogram of liquid hydrogen it delivered and on its power purchase agreements, which are long-term contracts to supply electricity and fuel to customer sites. Management built its turnaround plan on raising fuel prices and running its hydrogen plants in Georgia, Tennessee and Louisiana more efficiently.
Those unit losses shrank again in the third quarter. Fuel gross margin improved to negative 51.9% from negative 79.3% a year ago as revenue grew 6.1% to $38.1 million, roughly matching the negative 48.2% rate in the second quarter. By our math, the gross margin on power purchase agreements improved to negative 16.1% from negative 85.2% a year ago and negative 30.0% last quarter.
What to watch: fourth-quarter fuel gross margin. Moving closer to breakeven on fuel is essential because equipment sales alone cannot cover the company's overhead.
🐻 Bear Case
Asset Sales Drove the Low Cash Burn
Plug Power highlighted record-low quarterly net cash usage — the drop in unrestricted cash on its balance sheet — of $28 million, down 54% from $61 million in the second quarter. The release stated: "The improvement in net cash usage reflects underlying business performance rather than capital raising activities." Unrestricted cash ended September at $134.1 million, and the company did not sell new shares during the quarter.
The cash flow statement tells a different story. By our math, subtracting six-month figures from the nine-month statement shows that everyday operations burned $76.4 million in cash during the third quarter, and capital spending took another $14.8 million. Plug Power bridged that $91.2 million free cash flow deficit by collecting $40.0 million from selling property and equipment and unlocking $40.8 million from restricted cash escrow accounts.
Relying on asset sales and escrow releases matters because unrestricted cash covers less than two quarters of operating burn at the third-quarter rate. Meanwhile, the company doubled its authorized common stock from 1.5 billion to 3.0 billion shares, expanding its capacity to issue new equity if asset sales slow down.
What to watch: fourth-quarter operating cash flow in the annual report. It will show whether core operations are actually using less cash or if asset sales are still doing the work.
Accounting Gains Created the Profit as Margins Slipped
"Our third quarter results reflect continued progress toward a stronger, more profitable Plug," chief executive Jose Luis Crespo said. The hydrogen supplier reported net income of $99.8 million, or $0.07 per share, compared with a loss of $0.31 a year ago. Gross margin improved by 65 percentage points from a year ago to negative 2.7%.
- Non-cash fair-value gains on convertible debt and warrants: $192.5 million ($0.12 per share)
- Net loss excluding those fair-value gains: $92.7 million by our math
- Gross margin excluding a $10.4 million service loss-contract benefit: negative 7.9% by our math
- Gain on selling property and equipment inside operating expenses: $25.8 million
Sequential progress stalled when stripping out one-offs. Reported gross margin stepped back from negative 0.9% in the second quarter to negative 2.7%, and equipment gross margin turned slightly negative at minus 0.4% despite higher revenue. Operating loss of $75.3 million benefited from a $25.8 million property sale gain that more than offset $16.6 million in asset write-downs. Meanwhile, past financing deals pushed the diluted share count up 32.7% from a year ago to 1.54 billion.
What to watch: fourth-quarter gross margin before service loss-contract releases. Reaching the year-end profit target requires equipment sales to generate positive gross profit.
Fourth-Quarter Targets Need a 38% Revenue Jump
Crespo kept the full-year outlook for revenue growth of 15% to 16% and reiterated the goal of positive EBITDAS — earnings before interest, taxes, depreciation, amortization and stock compensation — in the fourth quarter. Third-quarter revenue rose 13.3% from a year ago to $200.6 million, bringing nine-month sales to $542.4 million.
By our math, hitting the middle of the full-year range requires $277.5 million in fourth-quarter revenue. That means sales must jump 38.4% from the third quarter and 23.2% from a year ago, lapping a tough fourth quarter of 2025 when electrolyzer shipments peaked. Reaching positive EBITDAS in the same quarter requires covering roughly $68 million in quarterly selling and administrative costs plus research expenses from a starting gross margin that is still negative.
What to watch: full-year 2026 revenue and fourth-quarter EBITDAS in the year-end release. Missing either target would test management's multi-year plan to reach positive operating income in 2027.
Risks this quarter didn't answer
Four standing concerns from prior quarters could not be checked from the third-quarter press release alone.
- Electrolyzer revenue: not broken out in the release after falling 71% in the second quarter; the quarterly filing's footnote will show if shipments rebounded.
- Total remaining performance obligations (RPO): not in the release; the filing's revenue footnote will show if the $668.6 million backlog grew.
- Carlton Power's remaining 25 megawatts: management previously expected a final investment decision in 2026, and the release gave no update.
- Remainder of the $275 million asset sale plan: after collecting $40 million from property sales in the third quarter, the timing for the rest of the program remains unstated.
💲 Other KPIs
Overhead costs fell 38.2% from $110.6 million a year ago under the Project Quantum Leap cost-cutting program. As a share of revenue, selling, general and administrative expenses dropped by 28.4 percentage points from a year ago to 34.1%, though they rose from $29.3 million in the second quarter, when a one-time legal recovery artificially lowered the line.
Uncollected bills owed by customers jumped 35.2% from $125.9 million in the second quarter and 26.3% from $134.8 million at the start of the year. That outpaced the 12.5% sequential rise in revenue and tied up $41.5 million of operating cash over the first nine months.
Stockpiled parts and equipment fell by $21.0 million from the second quarter and by $48.5 million since December. With one quarter left, the hydrogen group is less than halfway to its full-year target of cutting inventory by at least $100 million, so hitting the goal depends on heavy fourth-quarter shipments.
🔮 Guidance
Unchanged. The plan still calls for full-year sales to rise 15% to 16% from 2025's $709.9 million, which puts the middle of the range at $820.0 million by our math. After $542.4 million in the first nine months, that leaves $277.5 million for the fourth quarter — a 38.4% jump from the third quarter and 23.2% growth from a year ago.
Unchanged. Management still targets positive earnings before interest, taxes, depreciation, amortization and stock compensation in the fourth quarter. Plug Power does not reconcile this figure to net income, and hitting it requires the fourth-quarter revenue jump to lift gross profit enough to cover roughly $68 million in quarterly cash overhead.
New. Plug Power "anticipates that cash usage may be relatively flat for Q4 2026" compared with the $28 million used in the third quarter. Against $134.1 million in unrestricted cash, holding that rate keeps liquidity intact through year-end, though third-quarter cash usage relied heavily on asset sales and released escrow funds.
❓ Key Questions
How much did electrolyzer sales recover in Q3?
Electrolyzer revenue dropped 71% from a year ago to $13.2 million in the second quarter. The third-quarter release highlighted new orders in Denmark and Australia but did not state how much electrolyzer revenue was actually booked in the quarter.
How will Plug fund cash burn once asset sales end?
By our math, third-quarter operating and capital cash burn was $91.2 million, offset by $40.0 million from property sales and $40.8 million from restricted cash releases. Investors need to know how much restricted cash and property inflows are assumed in the fourth-quarter cash outlook.
Why did Plug double its authorized shares to 3 billion?
The balance sheet shows authorized common stock rose from 1.5 billion to 3.0 billion shares during the quarter. Although Plug raised no equity in the third quarter, the increase creates room for substantial future share issuance.
How much of the implied $278M Q4 revenue is already booked?
Hitting the full-year outlook requires fourth-quarter revenue to rise 38% from the third quarter. Management has not disclosed how much of that fourth-quarter equipment volume sits in current backlog versus orders it still needs to close and ship before December.
