Plug Power Inc (NASDAQ: PLUG) is a hydrogen energy company that designs, manufactures, and operates hydrogen fuel cell systems, electrolyzers, and hydrogen production and fueling infrastructure. Revenue comes from equipment sales, hydrogen fuel delivery, and service contracts, primarily under its GenKey turn-key bundled offering that combines fuel cell power, hydrogen fuel, and aftermarket maintenance. Plug operates as a vertically integrated supplier across the hydrogen value chain, from production and liquefaction through dispensing and end-use power, with more than 74,000 fuel cell systems deployed and more than 275 fueling stations in operation as of the 10-K filed March 2, 2026. The company was incorporated in Delaware on June 27, 1997, and is headquartered in the United States. As of FY2025, it operated hydrogen production plants in Tennessee, Georgia, and Louisiana, with Louisiana commissioned in April 2025. Plug has pursued a restructuring program called Project Quantum Leap since 2024, involving workforce reductions, facility consolidation, and pricing increases to improve margins.

Revenue model

Plug generates revenue through equipment sales (fuel cell systems, electrolyzers, liquefiers, cryogenic solutions), hydrogen fuel delivery and production, and recurring service contracts under the GenCare maintenance program. The GenKey offering bundles equipment, fuel, and service into a single turn-key contract. The company also earns revenue from power purchase and service agreements.

Products and services

GenDrive (PEM fuel cell systems for material handling EVs including forklifts and automated guided vehicles), GenFuel (liquid hydrogen fueling, delivery, generation, storage, and dispensing), GenCare (IoT-based maintenance and on-site service), GenKey (turn-key bundled solution), GenSure (stationary fuel cell backup power), GenEco electrolyzers (5MW and 10MW modular PEM electrolyzer systems), hydrogen liquefiers, liquid hydrogen cryogenic solutions (storage tanks, delivery trailers, vaporizers), and hydrogen production facilities.

Customers and end markets

Primary end market is material handling, including warehouse and distribution center forklift fleets. Additional target markets include supply chain and logistics, e-mobility, stationary power generation, and industrial applications. The filing does not disclose specific customer names or revenue concentration percentages.

Value-chain role

Vertically integrated across the hydrogen value chain: produces hydrogen at owned facilities, liquefies and transports it, dispenses it through owned fueling stations, and manufactures the fuel cell systems and electrolyzers that consume it. Also sells production equipment (electrolyzers, liquefiers) to third parties.

Geographic exposure

Primarily United States, with hydrogen production plants in Tennessee, Georgia, and Louisiana as of April 2025. The company has international operations and assets denominated in foreign currencies, with contracts primarily denominated in U.S. dollars. Plug is planning hydrogen network expansion in Europe.
