Approach 1: Enphase Energy Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model projects the cash that a company could generate in the future and discounts those projections back to today to arrive at an estimate of what the stock might be worth now.

For Enphase Energy, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month Free Cash Flow is reported at about $136.2 million. Analysts provide explicit Free Cash Flow estimates for several years, and Simply Wall St then extrapolates further out, with projected Free Cash Flow of $419.8 million in 2030, all expressed in dollars.

Using the full set of projected cash flows and discounting them back to today results in an estimated intrinsic value of about $34.53 per share. Compared with the recent share price of around $50.57, the DCF output suggests the stock is trading at a premium, with the model indicating it is about 46.4% overvalued on this basis.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Enphase Energy may be overvalued by 46.4%. Discover 47 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Enphase Energy Price vs Earnings

For a profitable company, the P/E ratio is a useful yardstick because it links what you pay today to the earnings the business is already generating. A higher or lower “normal” P/E typically reflects what investors expect for future growth and how much risk they see in those earnings.

Enphase Energy currently trades on a P/E of 49.37x. This sits below the semiconductor industry average of 61.00x and well below the peer group average of 109.20x. On these simple comparisons alone, the stock appears cheaper than many peers.

Simply Wall St’s “Fair Ratio” is designed to go a step further. It estimates what P/E might be reasonable after adjusting for factors such as Enphase Energy’s earnings growth profile, industry, profit margins, market cap and key risks. For Enphase, that Fair Ratio is 55.14x, which can be a more tailored benchmark than broad industry or peer averages that do not adjust for these company specific drivers.

Comparing the current P/E of 49.37x with the Fair Ratio of 55.14x indicates that the stock trades below this customised benchmark on this measure.

Result: UNDERVALUED

Fair Value: about US$72.31 per share

Implied discount to this Fair Value at US$50.57: about 30.0% below the narrative Fair Value

Revenue growth assumption: 14.8% a year

• Views Enphase as using solid state transformers and GaN based products to improve margins and broaden into power infrastructure beyond residential solar.
• Leans on Enphase's installed base of nearly 5 million homes and AC coupled platform to support higher margin cross selling into batteries, EV charging and international markets.

Fair Value: about US$45.75 per share

Implied premium to this Fair Value at US$50.57: about 10.5% above the narrative Fair Value

Revenue growth assumption: 1.0% a year

• Anchors on a more cautious analyst consensus that expects relatively flat revenue, only modest margin improvement and a tighter P/E multiple by 2029.
• Highlights headwinds from the expected 20% contraction in the US residential solar market after the 25D tax credit expiry, tariff pressures on hardware and elevated channel inventory.
• Points to execution risk around frequent product launches, potential industry consolidation toward larger installers and the possibility that Enphase's earnings trajectory remains constrained if demand or pricing disappoints.
