Another View: Plug Power Looks Expensive On Sales

While the most followed Plug Power narrative points to a $2.83 fair value using future earnings assumptions, the current P/S ratio of 4.8x is far higher than the US Electrical industry at 2.7x, the peer average at 1.4x and a fair ratio of 0.8x.

This gap means investors today are paying far more per dollar of Plug Power revenue than both peers and the fair ratio suggest. This raises the question: how comfortable are you with paying a premium while the company is still loss making and facing funding pressure?
