Exhibit 99.1 Plug Power Second Quarter 2025 Highlights · Execution on Project Quantum Leap helps accelerate business sales growth and financial performance · Q2 revenue up 21% year-over-year, driven by broad hydrogen demand LATHAM, N.Y., August 11, 2025 — Plug Power Inc. (NASDAQ: PLUG), a global leader in comprehensive hydrogen solutions for the hydrogen economy, today announced its financial results and operational milestones for the second quarter ended June 30, 2025. Revenue Growth and Run Rate Momentum · Plug reported $174 million in Q2 revenue, a 21% increase versus Q2 2024, driven by robust demand for its GenDrive fuel cells, GenFuel hydrogen infrastructure, and GenEco electrolyzer platforms. · Electrolyzer revenue tripled year-over-year, reaching ~$45 million in Q2, as the business scales globally. Gross Margin, Operating Expenses, and Cash Flow Improvements · Gross margin for Q2 2025 improved significantly to -31% from -92% in Q2 2024, a result of service cost reductions, equipment cost improvements, and improved hydrogen pricing. · Continued execution of Project Quantum Leap delivered cost structure gains through: o Optimization of the workforce o Consolidation of facilities o Reduction in professional services and software costs o Renegotiated supply contracts, including a new hydrogen gas agreement expected to lower molecule cost in H2 2025 and onward · The second quarter had approximately $80 million in non-cash charges largely associated with Project Quantum Leap. This compares to approximately $6 million in Q2 2024 for similar activities. Cash Flow and Liquidity · Net cash used in operating and investing activities declined over 40% year-over-year. · Plug exited Q2 with over $140 million in unrestricted cash and cash equivalents, and a platform to access over $300 million in additional debt capacity from the Company’s secured debt facility. · The Company is also positioned to benefit from monetization of tax credits under Sections 45V and 48E.

Strategic and Market Highlights GenEco Electrolyzer Growth and Global Expansion · Over 230 megawatts of GenEco electrolyzer programs are currently being mobilized across Europe, Australia, and North America, reflecting strong global demand and Plug’s leadership in delivering industrial-scale hydrogen solutions. · In April, Plug’s Georgia hydrogen plant set a U.S. production record using GenEco systems — a milestone that demonstrates the scalability, reliability, and cost-effectiveness of our technology, underscoring Plug’s ability to execute at scale and deliver high- volume, dependable hydrogen powered by GenEco electrolyzers. · The GenEco electrolyzer sales funnel remains exceptionally strong, with additional customer commitments expected this year and multiple large-scale projects moving toward final investment decisions in 2026. Plug is also pursuing pre-FID agreements to secure long-term value earlier in the development cycle, reinforcing our leadership position in the global electrolyzer market. Strengthened Hydrogen Supply and Customer Confidence · A major hydrogen supply agreement was extended with improved economics, supporting better margins in the second half. · GenEco has become the electrolyzer platform of choice for industrial-scale applications in oil refining, chemicals, mining, semiconductors, steel, cement and more. Positioned for Growth in GenDrive Material Handling · The extension of the Investment Tax Credit (ITC) through 2026 is stimulating customer demand for Plug’s GenDrive fuel cells for material handling solutions. The Company expects this momentum to drive new bookings in the second half of 2025, setting the stage for significant growth in 2026. Advancing Plug’s Energy Transition business with Proven Expertise · Plug’s Energy Transition business is gaining traction as the Company leverages its expertise in skid packaging and liquefier technology to support customers in industries including renewable diesel and sustainable aviation fuel (SAF). This capability is expected to open new revenue opportunities in the second half of 2025. Tax Credit Clarity Helps Accelerate Growth · The passage of the One Big Beautiful Bill in July was a major policy win, solidifying the Section 45V Clean Hydrogen Production Tax Credit and the Section 48E Investment Tax Credit: o 30% ITC for qualified fuel cell properties (2026–2032) o Preservation of the PTC with direct pay and transferability for hydrogen projects beginning construction before 2028 Focus on Gross Margin Neutrality · Plug expects to achieve gross margin breakeven on a run-rate basis in Q4 2025. · Continued cost discipline, enhanced service execution, and scale benefits from GenEco deployments positions the Company to achieve this goal.
