Frequently Asked Questions
What is the PE ratio of ENPH?
The trailing twelve-month PE ratio of ENPH reflects how much investors pay per dollar of Enphase Energy, Inc.'s earnings. This metric is most useful when compared to Solar peers and the company's own historical range.
Is ENPH overvalued based on PE ratio?
ENPH's PE of 34.4x combined with a PEG ratio of -1.55 provides a growth-adjusted perspective. ENPH has negative earnings, so its PE and PEG ratios are not meaningful here and cannot tell you whether the stock is over or undervalued. Keep in mind that PE-based valuation works best for profitable, mature companies — for high-growth or cyclical Solar, a DCF analysis may be more appropriate.
How do I value ENPH stock using PE ratio?
To value Enphase Energy, Inc. using PE: (1) Compare the current PE (34.4x) against the Solar median to assess relative pricing, (2) check the PEG ratio (-1.55) to adjust for growth expectations, (3) review the 5-year PE range to identify where the stock sits historically, and (4) estimate fair value by multiplying a target PE by forward EPS estimates. This relative approach complements DCF's absolute valuation.
What is the PEG ratio of ENPH?
ENPH's PEG ratio is -1.55, calculated by dividing the PE ratio (34.4x) by the expected earnings growth rate. Because ENPH has negative earnings, its PEG ratio is not meaningful and should not be read as a sign of under or overvaluation. Note that PEG accuracy depends on the reliability of growth estimates.
Should I use PE ratio or DCF for ENPH stock valuation?
PE ratio gives a quick relative read — how ENPH is priced versus Solar peers. DCF provides an absolute value based on projected free cash flows. For the most reliable valuation, use PE as a quick comparability screen and DCF for a deeper fundamental analysis. Each method has blind spots: PE ignores capital structure and cash flow quality, while DCF is sensitive to growth and discount rate assumptions.
