CFO Paul Middleton Is Buying Plug Power Stock Again. Should You?

Plug Power (PLUG) has been navigating challenging waters throughout 2025, with the stock tumbling amid regulatory hurdles and liquidity concerns. However, Chief Financial Officer Paul Middleton recently made headlines by substantially increasing his stake in the company. Middleton’s latest purchase of 650,000 shares of PLUG stock follows an earlier insider buy, signaling a clear vote of confidence from one of the company’s top executives. The timing of this insider purchase is particularly noteworthy, coming just after Plug Power requested shareholder approval for a reverse stock split and an increase in authorized shares — moves typically viewed by investors as defensive measures to stabilize the business.

In this article, we’ll examine Middleton’s recent insider activity, dive into Plug Power’s broader operational and financial health, and evaluate whether investors should interpret the CFO’s buying as a compelling signal to follow his lead and purchase PLUG stock — or if caution remains the wiser path forward.
