Plug Power Inc. shares surged 7.55% to close at $2.85 on Thursday, outperforming the broader market in the final trading session before the Juneteenth holiday. The move came as investors focused on the company's improved liquidity following a $39.2 million tax credit sale and narrowing gross margin losses, despite the absence of new earnings data.
The stock's gain outpaced the Nasdaq Composite, which rose 1.91% on the day. U.S. markets were closed on Friday for Juneteenth, making Thursday the last trading day of the week. Plug Power's rally followed two consecutive sessions of decline, with the stock closing at $2.65 on Wednesday before rebounding sharply.
Over the full trading week, Plug Power shares gained approximately 3.3%, rising from $2.76 on June 12 to $2.85 on June 18. This recovery comes after a challenging period that saw the stock drop 2.47% last Friday, marking its eighth consecutive losing session at that point.
The broader market also posted gains on Thursday, with the S&P 500 rising 1.1%, the Dow Jones Industrial Average adding 0.1%, and small-cap stocks surging 2.1%. Treasury yields edged lower, according to data from the Associated Press.
Plug Power's rally was part of a broader move in hydrogen and fuel-cell stocks. FuelCell Energy Inc. surged 19.96% to close at $24.04, while Ballard Power Systems Inc. added 5.05%. This coordinated move suggests that Plug Power's gains were not solely company-specific but also driven by sector-wide momentum.
Despite the positive price action, Plug Power shares remain nearly 38% below their 52-week high of $4.58. The company's core investment thesis hinges on its ability to improve liquidity and margins. In the first quarter, Plug Power reported revenue of $163.5 million, up 22% year over year, and a gross margin of negative 13%, an improvement from negative 55% in the prior year period.
On June 2, the company announced the completion of a federal investment tax credit sale related to its St. Gabriel, Louisiana hydrogen liquefaction plant, bringing in approximately $39.2 million. CEO Jose Luis Crespo stated that the transaction would “enhance financial flexibility,” while CFO Paul Middleton described it as part of a “disciplined financial strategy.”
Management has reiterated its target of achieving positive EBITDAS (earnings before interest, taxes, depreciation, amortization, and stock-based compensation) in the fourth quarter of 2026. However, risks remain. The company reported a GAAP loss of $0.18 per share in the first quarter and continues to operate with a negative gross margin. If the recent rally is driven primarily by short covering or sympathy with other fuel-cell names, investors may soon refocus on concerns about cash burn, potential dilution, and the timeline for hydrogen demand to translate into sustainable profitability.
