On March 9, 2026, Jefferies cut its price target on Plug Power Inc. (NASDAQ:PLUG) to $1.80 from $2.00 while maintaining a Hold rating, pointing to concerns about whether the company’s improving margin profile can be sustained. The note said Plug reiterated its expectation for positive EBITDA in 2026, but Jefferies still views that outlook as a “show me” story.
The firm also said Plug’s fourth-quarter gross margin benefited partly from one-off items, even as it acknowledged better liquidity and expected performance support from material handling and electrolyzers in 2026. For context, Plug reported fourth-quarter 2025 revenue of $225.2 million, up 17.6% from the prior-year quarter, while full-year 2025 revenue rose 12.9% to about $710 million. The company posted a positive fourth-quarter gross profit of $5.5 million, or 2.4% of sales, versus a gross margin loss of negative 122.5% a year earlier.
