8x versus Generac Holdings Inc. at 99. 2x. On forward P/E, EnerSys is actually cheaper at 21. 6x. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: EnerSys wins at 0. 94x versus Hubbell Incorporated's 1. 20x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.
