<div id="readability-page-1"> <time datetime="2025-11-21T18:00:00.000Z"> 11/21/2025 - 01:00 PM </time> SLINGERLANDS, N.Y., Nov. 21, 2025 (GLOBE NEWSWIRE) -- Plug Power Inc. (NASDAQ: PLUG) (the “Company” or “Plug”), a global leader in comprehensive hydrogen solutions for the hydrogen economy, will hold a Special Meeting of Stockholders (the “Special Meeting”) on January 15, 2026, at 10:00 a.m. Eastern Time. The meeting will be conducted in a virtual format only. Purpose of the Special Meeting At the upcoming Special Meeting, Plug will ask stockholders to approve an amendment to the Company’s charter to increase the authorized common stock from 1.5 billion to 3.0 billion shares. Plug currently has less than 0.4% of its authorized shares of common stock available for future issuance. The proposed increase, made in consultation with Institutional Shareholder Services (ISS), was based on a sizing analysis that considered projected capital requirements, upcoming contractual commitments, equity programs, and potential strategic transactions, ensuring flexibility without excess. Plug’s stockholders will also be asked to approve an amendment to the Company’s charter to conform the Company’s charter to recent amendments in the Delaware statute. This amendment would allow a more achievable voting standard for, among other things, future amendments to increase or decrease the authorized number of shares of common stock and align the voting standard with other Delaware companies. The Company filed a preliminary proxy statement with the Securities and Exchange Commission (the “SEC”) on November 20, 2025. For additional information regarding these proposals, investors are urged to read the Company’s preliminary proxy statement. Plug’s Board of Directors recommends a vote FOR each of these proposals as these are in the Company’s best interest. Recent Business Progress and Operational Momentum Plug continues to make meaningful progress across its business, reinforcing the Company’s position as a global leader in integrated hydrogen solutions: <ul type="disc"><li>Record Hydrogen Production. Plug’s Georgia plant delivered its best month on record in August 2025, producing 324 metric tons of hydrogen with 97% uptime and 99.7% availability, demonstrating strong performance of Plug’s end-to-end production technology.</li><li>Expanding Electrolyzer Deployments. Plug is advancing a multi-gigawatt electrolyzer development pipeline, with 8 GW+ of identified opportunities across Europe, Australia, the Middle East and North America, reflecting rising global demand for clean hydrogen.</li><li>Continued Expansion in Material-Handling Fuel Cells. Plug recently commissioned next-generation GenDrive fuel-cell systems for major logistics operators, including new deployments at Floor &amp; Decor’s Frederickson distribution facility, reinforcing Plug’s leadership in large-scale material-handling fleets.</li><li>Strengthened Customer Ecosystem. Plug’s annual symposium convened industry partners including Amazon, Uline, Hy2Gen, and key energy developers, highlighting broad commercial support for Plug’s integrated hydrogen solutions.</li><li>Advancing Energy Transition Infrastructure. Plug is expanding hydrogen storage, delivery and fueling capabilities to support emerging industrial and data center demand, positioning the Company as a full-value-chain provider for the clean hydrogen economy.</li></ul> “These proposals are essential to ensuring Plug has the resources and flexibility needed to execute on our strategy, meet contractual obligations, reward talent, and advance the hydrogen economy,” said Andy Marsh, Chief Executive Officer of Plug. “We are encouraged by the progress we’re making across production, electrolyzers, and commercial adoption, and we remain focused on driving disciplined growth and creating sustainable value for our stockholders.” Protect Your Investment The record date for the upcoming Special Meeting is December 4, 2025.
