Plug Power Stock Slips Tuesday: What's Driving The Action?

By Henry Khederian | February 17, 2026, 1:24 PM

Plug Power Inc (NASDAQ:PLUG) shares are trading lower Tuesday, reversing part of last week's jump after shareholders approved a sharp increase in the hydrogen company's share authorization and disclosed the move in a new SEC filing. Here’s what investors need to know.

Shareholders Double Authorized Plug Power Share Count

At a Feb. 12 special meeting, investors voted to raise Plug's authorized common shares to 3.0 billion from 1.5 billion, according to a Form 8-K filed Feb. 13. The change gives the fuel-cell maker more room to issue equity without returning for another vote, while a separate proposal to alter voting requirements failed.

The extra capacity also means Plug can pursue funding without resorting to a reverse split that had previously been considered, a step that can add volatility and unsettle investors.

Why The News Matters For PLUG Stock

Management now has a larger equity cushion to refinance debt, fund hydrogen plants and infrastructure, and support large industrial and data-center customers. That financial flexibility could buy time for Plug to execute its strategy and move toward positive cash flow.

The downside is dilution. Any sizable stock offerings will spread future gains across a much larger share base, pressuring earnings per share and limiting upside if growth lags. With PLUG slipping despite last week's favorable vote, the market appears to be balancing dilution worries against the strategic benefits of improved access to capital.

Shares Near Key Support

Currently, Plug Power is trading 9.8% below its 20-day simple moving average (SMA) and 4.1% below its 100-day SMA, indicating short-term weakness while the longer-term trend remains more stable.

Shares have decreased by 1.5% over the past 12 months and are positioned closer to their 52-week lows than highs, reflecting ongoing challenges.

The RSI is at 44.45, which is considered neutral territory, while the MACD is below its signal line, indicating bearish pressure on the stock. This combination suggests that while the stock is not in oversold territory, it is also not showing signs of a strong rebound.

The combination of neutral RSI and bearish MACD indicates mixed momentum, suggesting that traders should be cautious in the current environment.
