SLINGERLANDS, N.Y., Nov. 21, 2025 (GLOBE NEWSWIRE) -- Plug Power Inc. (NASDAQ:PLUG), a global leader in comprehensive hydrogen solutions for the hydrogen economy, today announced the successful closing of the previously announced offering of $375 million aggregate principal amount of 6.75% convertible notes due 2033, including the full exercise of the initial purchasers' option to purchase an additional $56.25 million aggregate principal amount of the notes, resulting in a total aggregate principal amount of $431.25 million.
