Ultra Clean Holdings, Inc. (UCTT): fair value, margin of safety and Wheel Score
Ticker symbol UCTT · Technology · Semiconductors · United States · Blend
Is UCTT undervalued?
UCTT closed at 44.04 on 5 Nov 2026, more than 30% above the GLS average fair value of 10.80. Only 0 of the 7 models that produced a value sit above the price. By our models the shares are priced well beyond what the filed earnings, cash flow and book value support; the "below fair value" Wheel Trade Filter keeps names like this under 70.
The 7 models disagree widely: DDM gives 0.0307 while Graham Growth gives 33.51. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.
Ranked against every other company we cover, neither cheapness nor growth clearly wins for UCTT, so the nightly engine files it under Blend (value score 18, growth score 27, out of 100).
Nine valuation models for UCTT
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. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.
| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | 2.50 | -94% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 14.53 | -67% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 33.51 | -24% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 14.65 | -67% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 3.85 | -91% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | - | - | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10%; no value tonight |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |
| DDM | 0.0307 | -100% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 6.51 | -85% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | 0.3086 | -99% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 107.33 | +144% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is weak: UCTT passes 4 of the nine Piotroski tests. Our scans drop the stock at the health filter; a low score is often the reason a stock looks cheap on the valuation models. The GLS Moat score is low at 3.7 out of 10: returns on capital, margins or the balance sheet have not shown a lasting edge yet - often a young company, a thin-margin business or one that has only recently turned profitable.
Returns on capital are thin or negative - ROIC -11.9%, ROE -25.5%, ROA -10.5% - with debt at 1.14 times equity and negative free cash flow.
The dividend yield is 0.00% with a payout ratio of 0% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Product 90%, Service 10% (quarter Q3 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 4 / 9 | ROIC | -11.9% |
|---|---|---|---|
| GLS Moat | 3.7 / 10 | ROE | -25.5% |
| Debt / equity | 1.14 | ROA | -10.5% |
| Free-cash-flow yield | -7.8% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 25: Weak
UCTT scores 25 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 3, below fair value - trades 308% above our fair value; and filter 4, financially healthy - Piotroski 4/9 (under 6); and filter 5, can repay its debt - 9.5 years to repay its debt (over 3); and filter 7, a premium worth selling - implied volatility 82% (over 80%), and the parts are thin too - value weak, premium fair, moat fair, health fair, red flags good, option trading fair, stability weak. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.
Implied volatility is 82%, above the 80% ceiling of the Wheel Trade Filter on premium. The premium looks generous, but moves of that size can blow through any strike. Chain open interest is 11,605 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 1.6M shares a day on a market cap of $2.1B, with a beta of 1.90 - 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 weak.
| 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 308% above our fair value |
| 4 | Financially healthy | Fails | Piotroski 4/9 (under 6) |
| 5 | Can repay its debt | Fails | 9.5 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 | Fails | implied volatility 82% (over 80%) |
| 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 | 308% above fair value | |
| Premium | Fair | implied volatility 82% | |
| Moat | Fair | moat 3.7/10 | |
| Health | Fair | Piotroski 4/9 | |
| Red Flags | Good | Red Flags score 80/100 | |
| Option trading | Fair | 1,607 contracts a day, 11,605 open interest | |
| Stability | Weak | beta 1.90, $2.1B company |
