Wall Street Zen downgraded Plug Power Inc. to Strong Sell from Sell on October 3, 2026.
The move came despite the company recently reporting a quarterly loss that was slightly better than analyst estimates and modest year-over-year revenue growth. Its negative profitability metrics remain under scrutiny.
Plug Power shares have been trading near their 52-week low. The downgrade followed shortly after an insider sold a significant number of shares under a pre-arranged trading plan.
Some analysts maintain a Buy rating following a recent electrolyzer supply deal announcement. Overall analyst consensus remains Hold.
