Plug Power Inc. (PLUG) shares surged more than 10% in early trading Tuesday before paring gains, as investors cheered first-quarter results that showed accelerating progress toward profitability for the hydrogen fuel cell pioneer. The stock was up 296% over the past 12 months, yet deep divisions remain over whether the rally can continue, as the company faces fundamental challenges that could limit its long-term growth.
The company reported results after the market close on May 11, building on its first-ever quarterly gross profit in the prior period. While still posting a gross loss, Plug Power narrowed its gross margin dramatically to negative 13% in the first quarter of 2026 from a staggering negative 55% a year earlier, marking the second consecutive quarter of substantial improvement that clearly signals its operations are gaining traction.
Revenue rose 22% year-over-year, driven by higher shipments in both its material handling and electrolyzer businesses. The margin improvement stemmed from better cost controls and the company’s long-running vertical integration strategy, which is finally bearing fruit as in-house green hydrogen production reduces reliance on third-party suppliers and delivers structural gains in fuel margins.
Analysts have turned increasingly bullish following the report, with several firms raising their price targets. Craig-Hallum lifted its target to $5 from $4, while B. Riley increased its objective to $5 from $3. Based on Monday’s closing price of $3.52, those targets imply roughly 42% upside from current levels, further boosting market sentiment.
Despite the massive run-up, many investors see further upside for Plug Power. The company has set a clear path to profitability, targeting positive EBITDAS (earnings before interest, taxes, depreciation, amortization, and stock-based compensation) by the fourth quarter of 2026. Hitting that milestone would mark a critical turning point for a company long criticized for burning cash. Additionally, the explosive growth of artificial intelligence has opened a new potential market for hydrogen, as data centers’ insatiable demand for power and lower cost sensitivity create opportunities for clean energy solutions.
Longer term, the global hydrogen market presents an enormous opportunity. Goldman Sachs has estimated the sector could be worth $12 trillion over the next two to three decades, with hydrogen uniquely positioned to decarbonize hard-to-abate industries such as aviation and steelmaking thanks to its flexibility and high energy density. With a market capitalization of just $4.4 billion, Plug Power remains a small player in what could become a transformative global industry.
However, significant risks remain that could derail the rally. The biggest challenge is cost competitiveness: hydrogen fuel systems still cannot compete economically with conventional fossil fuels or even other renewables like wind and solar.
Goldman Sachs’ bullish outlook relies heavily on the assumption that governments worldwide will implement aggressive policies to either subsidize hydrogen or tax competing fuels to level the playing field. The International Energy Agency echoed this view in a recent report, noting that hydrogen projects will depend on policy action to close the cost gap with unabated fossil fuel-based hydrogen. This means companies like Plug Power are not fully in control of their own destiny, and widespread adoption could be years or even decades away without swift regulatory changes.
Adding to concerns, Plug Power’s net loss widened sharply in the first quarter due to non-cash charges including higher fair value of convertible debt, underscoring that the company is still far from full profitability.
Overall, Plug Power’s latest earnings represent a significant milestone, demonstrating that its strategic investments are finally paying off. While near-term momentum from improving fundamentals and AI-related demand could support further gains, the stock’s long-term trajectory will ultimately depend on two factors: the pace of global hydrogen policy implementation and the company’s ability to continue driving down costs.
