Despite finishing on a high note, the past month has seen Plug Power’s (PLUG) stock pullback significantly; the share price now sits ~50% below the 12-month high reached toward the end of January. While growth stocks have indeed taken a beating, the bear case for Plug was exacerbated by poor Q4 earnings, with the company alarming investors by reporting negative revenue for the quarter. The negative top-line was due to warrants the company handed to major customer Amazon back in 2017.
