Separately, TheStreet Ratings team rates PLUG POWER INC as a Sell with a ratings score of D-. TheStreet Ratings Team has this to say about their recommendation:

This is driven by a few notable weaknesses, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The company's weaknesses can be seen in multiple areas, such as its deteriorating net income and weak operating cash flow."
