Short Sellers Circle Plug Power as Q1 Results Put Turnaround to the Test

Plug Power reports Q1 2026 results on May 11 amid a 40% rally. Analysts expect a net loss of $0.09-$0.10 per share and revenue near $140M, with focus on margin trajectory and short squeeze risk.

The hydrogen fuel cell company Plug Power faces a pivotal moment on Monday, May 11, when it releases first-quarter 2026 results. After a blistering rally that has lifted the stock nearly 40% since the start of the year, the numbers will either validate the turnaround story or expose its fragility.

Analysts are bracing for a net loss of between $0.09 and $0.10 per share for the January-to-March period, with revenue expected to climb to roughly $140 million to $142 million. That would represent an increase of about 4.6% from the same quarter last year, driven largely by service contracts and long-term power purchase agreements.

A Hard-Won Margin Milestone

The optimism surrounding Plug Power stems from a genuine operational shift. In the fourth quarter of 2025, the company achieved its first-ever positive gross margin of 2.4%, a breakthrough that sent a clear signal to the market. Full-year 2025 revenue exceeded $700 million, up nearly 13% from the prior year, though the net loss remained substantial at $1.69 billion.

New chief executive Jose Luis Crespo, who took the helm in March 2026, has laid out an ambitious roadmap: positive EBITDA by the end of this year and full profitability by 2028. A major vote of confidence came in April, when Plug Power secured a 275-megawatt electrolyzer contract with Hy2gen in Canada, one of the largest projects of its kind globally.

Yet headwinds persist. Tariffs on Chinese components and European electrolyzers are disrupting the supply chain, adding cost pressure just as the company tries to cement its recovery.

Institutional Backing Meets Heavy Short Interest

Institutional investors remain committed despite the risks. Vanguard held roughly 73 million shares as of late March, representing just over 5% of outstanding stock. In total, about 43.5% of Plug Power’s shares are in institutional hands, a sign that professional money managers see long-term potential.

The short side tells a different story. Nearly 25% of the float is sold short, a level that amplifies price swings dramatically. If Monday’s results confirm the margin trajectory, short sellers could face intense pressure. A miss, on the other hand, would likely erase the gains of recent months in short order.

Analyst Views Diverge

The stock closed Friday at €2.65, roughly 20% above its 50-day moving average and a far cry from its 52-week low of €0.63. To reach the 52-week high of €3.51, the shares would need to climb another 24%.

Wall Street is split on the outlook. Clear Street rates the stock a buy with a price target of $3.50, seeing further upside. Susquehanna is neutral at $2.75, while Jefferies is more cautious, rating it a hold with a target of just $1.80. The consensus sits at "hold."

Chart technicians have flagged a rising wedge formation in the stock’s price action, a pattern that often resolves to the downside. That technical warning makes the fundamental confirmation on May 11 all the more critical.

A strong report that beats expectations and shows continued margin improvement could trigger a short squeeze and propel the stock higher. A disappointment, particularly one accompanied by hints of another capital raise, would revive dilution fears and put the entire turnaround narrative back on trial.
