NASDAQ:PLUG 1 June 2026 - 23 June 2026

Plug Power Inc. stock was little changed Tuesday, with shares struggling to bounce back after dropping Monday. Investors looked at the hydrogen firm's higher revenues and better margins but stayed cautious on its ongoing cash requirements.

Plug Power Inc. will start the week trading above $2.80 after shares bounced on Thursday. The stock didn’t see any action on Friday, since Nasdaq stayed shut for Juneteenth on June 19. Nasdaq’s regular hours are 9:30 a.m. to 4:00 p.m. Eastern, Monday through Friday.

Plug Power stock managed a late-week bounce, finishing up 7.55% at $2.85 on Thursday.

The stock’s market value was about $3.82 billion, while its negative earnings per share and negative price-to-earnings ratio — a valuation measure comparing share price with profit per share — underline that investors are still valuing the company on turnaround potential rather than current profits.

Plug Power Inc. shares stayed weak early Friday. The hydrogen fuel-cell company fell 1.05% to $2.83 Thursday, even as the Nasdaq gained 2.54% and the Dow finished up 1.86%.

Plug Power slipped 2.7% to $3.59 in premarket action Thursday. The hydrogen fuel-cell maker had dropped 9.8% Wednesday to finish at $3.69. Premarket is the trading session before exchanges open, and price swings can be more volatile with lighter volume.
