NEW YORK, December 30, 2025, 02:22 ET — Market closed
Plug Power (PLUG.O) shares fell 4.83% to close at $1.97 on Monday, extending a two-day slide as the Nasdaq Composite slipped 0.50%. Trading volume was 72.2 million shares, below the stock’s 50-day average of 106.7 million, and the move lagged peer Ballard Power Systems (BLDP) which fell 2.28%.
The drop keeps the hydrogen fuel-cell and electrolyzer maker pinned near the $2 level heading into the final stretch of the year, a price zone traders often treat as a sentiment marker in high-volatility small caps. Plug’s investor relations stock quote page shows a 52-week high of $4.58 and a 52-week low of $0.69.
The bigger question for investors is whether Plug can convert project headlines into enough fourth-quarter revenue to meet its full-year target. Zacks Equity Research wrote in a note published on Nasdaq that Plug is aiming for about $700 million in 2025 revenue after reporting $484.7 million in the first nine months; it said electrolyzer revenue rose 61% year-on-year and made up 24.7% of total revenue, leaving Plug needing roughly $215 million in the fourth quarter to reach the goal.
Electrolyzers are machines that use electricity to split water into hydrogen, and Plug has been positioning them as a growth driver alongside its hydrogen supply network. In a December 17 press release, the company said it installed a 5-megawatt GenEco electrolyzer for Cleanergy Solutions Namibia at a site that pairs a 5-megawatt solar park with a 5.9 MWh battery system; “Projects like Cleanergy Solutions Namibia demonstrate how green hydrogen is moving from concept to commercial reality,” said Jose Luis Crespo, Plug’s president and chief revenue officer. ir.plugpower.com
Earlier this month, Plug said it signed a letter of intent with Hy2gen for a 5-megawatt PEM electrolyzer at the Sunrhyse project in southern France. (PEM stands for proton-exchange membrane, a type of electrolyzer design; RFNBO is an EU label for renewable fuels made from non-biological sources, such as renewable electricity.)
Plug has also been pushing into liquid hydrogen supply, which it argues can broaden its customer base beyond material-handling and industrial users. The company said on December 1 it began its first NASA liquid hydrogen contract, with an award valued at up to $2.8 million to supply up to 218,000 kilograms to NASA’s Glenn and Armstrong facilities in Ohio.
Another corporate catalyst sits on the calendar in January. Plug’s website says shareholders of record as of December 12 can vote at a January 29 special meeting on proposals including doubling authorized common shares to 3.0 billion from 1.5 billion; it also says the company would implement a reverse stock split if the share increase is not approved. (A reverse split reduces share count and lifts the per-share price, without changing the company’s underlying value.)
Before the next session, traders will watch whether PLUG can hold the $2 area on heavier volume, or whether thin year-end liquidity keeps amplifying swings. Rate expectations and equity risk appetite remain a key lever for loss-making clean-energy names that rely on capital markets.
The next major checkpoint is earnings. Zacks’ earnings calendar lists Plug’s next earnings release as expected on March 2, 2026, with a consensus loss estimate of $0.11 per share, though the company has not confirmed the date.
