Plug Power (NASDAQ: PLUG) reported a quarterly profit of $99.8 million for the third quarter of 2026, but a closer look reveals that the bottom line was heavily influenced by noncash gains. The hydrogen company recorded an operating loss of $75.3 million, underscoring the challenges in its core business of selling hydrogen equipment and fuel.
The $192 million in noncash gains, stemming from valuation adjustments on convertible debt and warrants, were nearly twice the profit attributable to shareholders. These gains, which resulted from a lower share price, do not generate any customer revenue or cash receipts. As CFO Paul Middleton noted on the earnings call, excluding these gains, the company would have reported a net loss.
Operational Improvements
Despite the accounting noise, there were signs of underlying improvement. Revenue rose approximately 13% year-over-year to $200.6 million. Gross margin, while still negative at 2.7%, was a significant improvement from the roughly negative 68% in the same period last year. Operating expenses also dropped sharply to about $70 million from $229 million.
CEO Jose Luis Crespo highlighted the company's progress, stating, "We grew revenue, improved margins, and significantly reduced cash usage through disciplined execution." The margin improvement was partly attributed to lower costs and fewer inventory valuation adjustments.
Segment Performance
Revenue growth was not uniform across segments. Equipment revenue increased 9.3% to $105.7 million, while fuel-cell service revenue jumped 47% to $29 million. The faster growth in services, while positive, should not be mistaken for equipment sales momentum.
Cash Use and Liquidity
Plug Power's cash management improved, with unrestricted cash declining by approximately $28 million in the quarter, down from $61 million in the previous quarter. However, this figure includes proceeds from asset sales. The company received about $46 million from its Stream asset transaction during the quarter, which exceeded the net cash decline.
At the end of September, Plug Power held approximately $134 million in unrestricted cash and $469 million in restricted cash. The restricted cash is not readily available for ordinary operating needs. The company is also working to release about $62 million in restricted cash tied to Texas power-supply collateral, with a target of March 2027.
Outlook and Risks
Management reaffirmed its forecast for 15%–16% full-year revenue growth, which implies roughly $280 million in fourth-quarter revenue, a 39.6% sequential increase. The company also targets positive fourth-quarter EBITDAS, a non-GAAP measure that excludes interest, taxes, depreciation, amortization, and share-based expenses.
However, these targets remain forecasts and do not guarantee positive operating cash flow or GAAP net income. Risks include hydrogen plant outages, timing of customer deployments, and dependence on Stream proceeds, which are subject to permitting. The company excluded Stream proceeds from its fourth-quarter cash forecast.
Investors should look beyond the headline profit figure and focus on the company's ability to generate sustainable revenue and cash flow from its core operations. The noncash gains, while flattering the bottom line, do not reflect the fundamental health of the business.
