Why Is PLUG PWR INC (PLUG) Stock Down Today?

Plug Power Inc. shares fell 7.33% to $1.39 on Monday, marking a sharp reversal from the prior session’s gains. The primary driver was the release of third-quarter 2026 financial results, where a reported quarterly profit was heavily influenced by noncash gains, while the company continued to post an operating loss.

What Happened

Plug Power reported a $99.8 million quarterly profit, a figure supported by approximately $192 million in noncash gains. Despite this headline number, the company still recorded an operating loss. Equipment sales for the quarter reached $105.7 million, while fuel cell services revenue surged 47% year over year. The company reaffirmed its full-year revenue growth forecast, expecting a 15% to 16% increase. Craig-Hallum cut its price target on the stock, citing timing uncertainty, while HC Wainwright & Co. maintained its Buy rating and $7.00 price target. RBC Capital reiterated a Sector Perform rating with a $2.00 price target.
