After the close on September 23, 2026, Plug Power stock was last quoted at USD 2.10 on the Nasdaq at 3:40 p.m. ET. The quote is an intraday level rather than a confirmed regular-session close, so the prior Nasdaq close of USD 2.09 on September 22, 2026, remains the latest substantiated closing price.
