Plug Power kept its 2026 revenuegrowth guidance of 15% to 16% in its third-quarter results release on 9 November. Measured against 2025 revenue of $709.9 million, that implies fourth-quarter revenue of $274.0 million to $281.1 million, by our arithmetic.
That would be 37% to 40% above the $200.6 million Plug reported for the third quarter, and above its best quarter in its SEC filings, $260.2 million in the second quarter of 2023.
Business Pill · Operating Leverage
An evergreen Business Engineer explainer on operating leverage. It teaches the general idea only and does not discuss Plug Power.
The key insight: Plug Power kept its 2026 revenuegrowth guidance of 15% to 16%. After $542.4 million in the first nine months, that implies fourth-quarter revenue of $274.0 million to $281.1 million, 37% to 40% above the third quarter and above any quarter in its SEC filings, by our arithmetic.
Plug’s 2025 revenue was $709.9 million, according to its annual report. Growth of 15% to 16% gives $816.4 million to $823.5 million for 2026. Revenue in the first nine months of 2026 was $542.4 million, which leaves $274.0 million to $281.1 million for the fourth quarter, by our arithmetic.
Plug’s fourth quarters have run higher before: the fourth quarter of 2025 brought $225.2 million, 27% above that year’s third quarter, by our arithmetic. The release’s own safe-harbor text refers to “the fourth quarter revenuegrowth required to achieve it”.
Quarterly revenue is from Plug Power’s SEC filings and its third-quarter 2026 release. The fourth-quarter 2026 range is our arithmetic from its 15% to 16% full-year growth guidance.
The Quarter
Revenue rose about 13% to $200.6 million from $177.1 million. Gross margin improved to about minus 3%, from about minus 68% a year earlier. Operating expenses fell about 69% to about $70 million, which the release attributes to reduced unusual charges and Project Quantum Leap.
GAAP basic EPS was about $0.07, against minus $0.31. The release says non-cash mark-to-market gains of about $192 million were “the primary reason the EPS was positive this quarter”.
Cash
Net cash usage fell to about $28 million from about $61 million in the second quarter. Cash and cash equivalents, excluding restricted cash, were about $134 million at quarter-end. The company says “cash usage may be relatively flat for Q4 2026” and that it raised no money through its ATM program or other equity or debt raises in the quarter.
Orders and Deployments
Plug deployed 1,136 GenDrive fuel cell units in the quarter, up 110% from 540. It signed a 280 MW GenEco electrolyzer supply agreement with Arcadia eFuels for Project ENDOR in Denmark, and secured a 50 MW order for Australia’s Hunter Valley Hydrogen Hub. Fuel revenue rose about 6% to about $38 million, at a gross margin of about minus 52%.
The Structural Read
As we read the release, the fourth quarter carries the year: the third quarter’s $200.6 million grew 13%, while the implied fourth-quarter range would be 22% to 25% above the $225.2 million of a year earlier.
As we read the cash line, the pressure eased but did not go away: net cash usage fell to about $28 million, leaving about $134 million of cash, and the company says usage may be relatively flat in the fourth quarter.
Jose Luis Crespo, Chief Executive Officer of Plug, in the results release
“We grew revenue, improved margins, and significantly reduced cash usage through disciplined execution.”
Three Implications
FOR CUSTOMERS Plug says it deployed 1,136 GenDrive fuel cell units in the quarter, up 110% from 540 a year earlier, and signed a 280 MW electrolyzer supply agreement with Arcadia eFuels.
FOR SHAREHOLDERS Plug says no proceeds were raised through its ATM program or other equity or debt raises during the quarter, and it targets positive EBITDAS in the fourth quarter.
FOR THE INCOME STATEMENT GAAP basic EPS of about $0.07 included non-cash mark-to-market gains of about $192 million, which the release calls the primary reason EPS was positive.
What Is Not Established
Plug does not give a fourth-quarter revenue figure, only the full-year growth rate, so the $274.0 million to $281.1 million range is our arithmetic. The release does not say which orders are expected to ship in the fourth quarter, and the Arcadia agreement’s value is not disclosed.

This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
Plug Power grew third-quarter revenue 13% and cut its cash usage to about $28 million, but its unchanged 15% to 16% growth guide implies fourth-quarter revenue of $274.0 million to $281.1 million, a level above any quarter in its SEC filings, by our arithmetic.
A note on sourcing. Results, cash, guidance and quotations are from Plug Power’s third-quarter 2026 results release (8-K Exhibit 99.1, 9 November 2026); earlier quarterly and annual revenue is from its SEC filings. The implied fourth-quarter range, its comparison with earlier quarters, and the record are our arithmetic.
