Plug Power’s Electrolyzer Breakout and Margin Pivot Clash with a $150 Million Quarterly Cash Burn

Plug Power's stock quintupled in 12 months driven by electrolyzer revenue surge and narrowing losses, but $150M quarterly cash burn and $8.2B deficit risk momentum.

Plug Power’s stock has more than quintupled over the past twelve months, climbing from below one euro to above three, and the shares now trade about 54% above their 200-day moving average. A golden cross on the charts and a short interest of roughly 25% of the free float suggest momentum could persist. Yet the company’s first-quarter results lay bare the central tension driving this rally: rapid operational improvements in the electrolyzer business and a steeply narrowing gross margin are coexisting with a $150 million quarterly operating cash outflow and a cumulative deficit that has swelled to $8.2 billion.

The electrolyzer segment has become the clearest source of narrative lift. Revenue from that unit jumped to $40.8 million in the first quarter from $9.2 million a year earlier. Stripping out the impact of customer warrants, the platform expanded by 343%. That explosive growth is being powered by project milestones in Europe – a 100-megawatt system with Galp Energia in Portugal, a 25-MW project alongside Iberdrola and BP in Spain – and a new 275-MW order in Canada with Hy2gen. Chief Financial Officer Paul Middleton described the moment in terms of execution: “Our hydrogen production network is built. We are now in the phase where we are utilising that asset base.”

The broader earnings picture also showed tangible healing. The adjusted loss per share came in at $0.08, halving the $0.17 deficit that analysts had anticipated. Gross margin improved from negative 55% a year ago to negative 13%. That figure remains in the red, but the direction of travel matters to investors who have been waiting for a credible path to profitability. Plug management reiterated its target of posting positive EBITDAS by the fourth quarter of 2026 and a positive operating result for 2027. For the second quarter, Middleton expects sequential revenue growth – albeit moderate – and further expansion in gross margin.

None of that erases the financial strain. Plug burned through $150 million in operating cash during the first quarter, and BMO Capital Markets flagged that the cash consumption was higher than anticipated. The company ended the period with $802 million in total cash, of which $223 million was freely available. Rather than tap equity markets, the company is monetising assets: sales of tax credits generated $39.2 million through May, and management expects total proceeds from such measures to exceed $275 million for the full year. Asset disposals, however, carry execution risk and provide limited room for error if the turnaround stalls.

Analyst opinion remains deeply divided. Out of 22 tracked ratings, only five carry a “Strong Buy” label, three stand at “Strong Sell” and the majority land at neutral. TD Cowen recently lifted its price target to $3.00 – a level the stock has already pierced – while B. Riley sees fair value at $5.00. With a days-to-cover ratio of 4.4 against average daily volume of 87 million shares, any sustained upside could force short sellers to scramble.

Meanwhile, structural tailwinds are growing. Data centre operators face grid connection delays of five to seven years, pushing on-site hydrogen and fuel cell solutions into sharper focus. In material handling, the core business unit grew 15% excluding warrant effects, and major customers Amazon and Walmart are planning large fleet renewals beginning in late 2026. Plug’s overall revenue target for the year remains 13% to 15% growth, with roughly 40% of that expected in the first half.

The second quarter will serve as the immediate test. If Plug can deliver sequential revenue improvement and a tighter gross margin without letting the cash burn spiral further, it will reinforce Middleton’s thesis that the asset base is finally earning its keep. If the cash drain persists, the stock’s dramatic run-up – already pricing in a great deal of hope – will face a harsh reality check.
