Enphase Energy, Inc. (ENPH): fair value, margin of safety and Wheel Score
Ticker symbol ENPH · Energy · Solar · United States · Growth
Is ENPH undervalued?
Enphase Energy, Inc. (ENPH) closed at 31.55 on 5 Nov 2026, 118% above the GLS average fair value of 14.46. 8 of the 8 models that produced a number value the shares below the current price. A gap this wide usually means the market is paying for growth or a story the trailing numbers do not show yet; the models work from filed results, not forecasts, so they are conservative by design.
There is a wide gap between GLS Growth (2.01) and 10 Cap (27.93). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
Ranked against every other company we cover, ENPH is clearly faster-growing than it is cheap, so the nightly engine files it under Growth (value score 13, growth score 40, out of 100).
Nine valuation models for ENPH
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number.

|---|---|---|---|
| DCF | 19.72 | -38% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 12.05 | -62% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 19.63 | -38% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 7.12 | -77% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 2.01 | -94% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 27.93 | -11% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 19.62 | -38% | Eight years of compounded free cash flow: the price at which the business pays for itself |

Quality and financial health
Enphase Energy, Inc. scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of the "Piotroski 6 or more" Wheel Trade Filter. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 4.8/10 is a weak reading: the accounts do not show returns and margins that competitors have been unable to wear down, so the Moat part of the Wheel Score contributes little.
Returns on capital are moderate - ROIC 7.4%, ROE 15.8%, ROA 4.9% - with debt at 1.14 times equity and a free-cash-flow yield of 3.2%.
Enphase Energy, Inc. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Reportable 100% (quarter Q3 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded insider buy was on 3 Nov 2026.
| Piotroski F-score | 5 / 9 | ROIC | 7.4% |
|---|---|---|---|
| GLS Moat | 4.8 / 10 | ROE | 15.8% |
| Debt / equity | 1.14 | ROA | 4.9% |
| Free-cash-flow yield | 3.2% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 32: Weak
With a Wheel Score of 32 Enphase Energy, Inc. sits in the Weak band. It fails filter 3, below fair value - trades 118% above our fair value; and filter 4, financially healthy - Piotroski 5/9 (under 6); and filter 5, can repay its debt - 4.2 years to repay its debt (over 3); Value (weak) is its weakest part.
Implied volatility is 73% on the near-the-money contracts 20-60 days out - above the 60% top of the sweet spot. It still passes the 25-80% filter, but the Wheel Score rewards it less because volatility this high usually comes with a reason. The option chain is deep: 175,358 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 17.0M shares a day on a market cap of $4.2B, with a beta of 1.63 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score rates that fair.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Passes | Listed options with 1,000+ contracts of open interest and 100+ traded a day |
| 2 | A real business, not a gamble | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Fails | trades 118% above our fair value |
| 4 | Financially healthy | Fails | Piotroski 5/9 (under 6) |
| 5 | Can repay its debt | Fails | 4.2 years to repay its debt (over 3) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Passes | Implied volatility 25-80% (enough premium, not a lottery ticket) |
| 8 | Big enough | Passes | Market cap $1 billion or more |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Weak | 118% above fair value | |
| Premium | Good | implied volatility 73% | |
| Moat | Fair | moat 4.8/10 | |
| Health | Fair | Piotroski 5/9 | |
| Red Flags | Weak | Red Flags score 62/100 | |
| Option trading | Strong | 49,907 contracts a day, 175,358 open interest | |
| Stability | Fair | beta 1.63, $4.2B company |
