New York, May 18, 2026, 12:04 (EDT)
- Plug Power shares fell about 9.8% to $3.41 in late-morning U.S. trading.
- The drop comes after a sharp post-earnings run tied to stronger first-quarter revenue and better margins.
- Investors are still weighing cash burn, losses and possible dilution against Plug’s 2026 profitability targets.
Plug Power Inc. shares fell sharply on Monday, giving back part of last week’s earnings-driven rally as traders reassessed whether the hydrogen company’s margin gains can outrun its losses and funding needs.
The stock was down about 9.8% at $3.41 in late-morning trading, after opening at $3.80 and touching an intraday low of $3.32. Trading volume was above 54 million shares, keeping the stock among the more active clean-energy names.
The move matters now because Plug’s first-quarter report had briefly changed the tone around the stock. The company posted revenue of $163.5 million, up 22% from a year earlier, and said gross margin improved to negative 13% from negative 55%; gross margin is the share of revenue left after direct costs, and a negative figure means those costs still exceed sales.
Chief Executive Jose Luis Crespo said the quarter reflected “strong commercial execution” and progress toward an EBITDAS-positive target in the fourth quarter. EBITDAS means earnings before interest, taxes, depreciation, amortization and share-based compensation, a profit measure that strips out several costs. ir.plugpower.com
The catch is still the bottom line. Plug’s quarterly filing showed a net loss attributable to the company of $245.3 million, compared with $196.7 million a year earlier, while cash, cash equivalents and restricted cash totaled $802.0 million at March 31.
Chief Financial Officer Paul Middleton told investors Plug ended the quarter with “over 10% more cash than we initially anticipated,” citing margin work and working-capital discipline. The company also said capital spending was about $7 million in the quarter as it shifts to using its built-out hydrogen production network. The Motley Fool
That has kept bulls interested. Canaccord analyst Jason Tilchen wrote after the results that Plug’s Project Quantum Leap was a restructuring and cost-optimization effort meant to speed its path to profitability and cut cash burn. Barron’s also reported that about 25% of Plug’s tradable shares had been sold short, making the stock prone to sharp moves when bearish traders cover positions.
The broader tape was not much help. U.S. indexes were mixed on Monday as Treasury yields eased but the Nasdaq slipped, with investors still sensitive to borrowing costs for growth companies whose value depends heavily on future earnings.
Other hydrogen and fuel-cell names were also under pressure. Bloom Energy fell about 5.8%, Ballard Power Systems dropped about 9.0%, and FuelCell Energy slid roughly 18.8%, suggesting Plug’s decline came amid a wider pullback in a volatile corner of the clean-energy trade.
Plug’s competitive pitch remains tied to scale. The company said it has more than 320 megawatts of electrolyzer capacity deployed globally and listed active projects with Galp in Portugal, Iberdrola and BP in Spain, and Hy2gen in Canada. Electrolyzers use electricity to split water into hydrogen and oxygen, a key process for producing so-called green hydrogen.
But the risk is that execution takes longer, costs stay high or Plug leans further on equity funding. The filing said the company believes its cash position and other resources can fund operations for at least 12 months, but it also points to at-the-market and standby equity arrangements; selling new shares can dilute existing holders, meaning each current share owns a smaller slice of the company.
For now, the stock is trading less on a single fresh announcement than on a harder question after last week’s relief rally: whether Plug’s better revenue and margins are enough to offset a still-large loss before the next earnings update.
