Plug Power is a hydrogen fuel cell company with 22% revenue growth and a deeply oversold RSI of 24, but its quality score of 2.2 out of 10 reflects severe cash burn at -55% of revenue, an extremely high short interest of 28%, and inconsistent earnings delivery that make it speculative at best.

About Plug Power, Inc.
About Plug Power, Inc.
Plug Power held $724.1 million in orders at December 31, 2025, spanning fuel cells, hydrogen installations, maintenance services, electrolyzers, and hydrogen fuel deliveries—with individual order terms ranging from 90 days to 10 years. The company has deployed more than 74,000 fuel cell systems since inception and operates more than 275 fueling stations, serving primarily large multi-shift distribution and manufacturing sites in North American and European material handling markets. Walmart accounted for 24.2% of fiscal 2025 revenues, with a second customer contributing another 14.3%.
Plug Power generates revenue across four integrated product lines: GenDrive PEM fuel cells for electric forklifts, GenFuel liquid hydrogen supply and dispensing infrastructure, GenCare maintenance and service programs, and GenEco modular electrolyzers in 5 MW and 10 MW configurations. Hydrogen production comes from three company-operated plants in Tennessee, Georgia, and Louisiana—the Louisiana facility, a joint venture with Olin Corporation named Hidrogenii, commenced operations in April 2025. The company manufactures fuel cell stacks at a gigafactory in Rochester, New York, and assembles finished systems in Slingerlands, New York. Key input materials for PEM fuel cells and electrolyzers include platinum, titanium, and iridium; iridium is produced primarily as a byproduct of platinum and nickel mining rather than mined directly, leaving supply dependent on demand for those primary metals. Single-sourced components exist for certain new technologies and product introductions, creating temporary supply gaps until alternate sources are qualified.
Show full overview
Iridium is the input most specific to Plug Power's electrolyzer growth plan. Unlike platinum, which trades on deep global markets, iridium is produced almost entirely as a low-volume byproduct of platinum-group and nickel mining, meaning supply is inelastic to iridium demand itself. The 10-K notes that even modest growth in PEM electrolyzer deployment industry-wide—a trend the company is actively targeting with its 5 MW and 10 MW GenEco products—could have an outsized impact on iridium pricing and availability. Industry efforts to reduce catalyst loading exist, but the company cautions that no assurance can be given that such efforts will succeed or prove commercially viable at scale.
