10-Q filed August 4: Ultra Clean

Ultra Clean Holdings reported revenue of $2.44bn for the twelve months to June 2026, a rise of 15.8% on the year, a marked acceleration from the 2.5% growth recorded a quarter earlier. Profitability told a mixed story over the same period. Operating margin widened to 4.3% from -4.4%, yet free-cash-flow margin slipped to -6.7% from 0.8% a year earlier, suggesting the improvement in reported earnings has not yet translated into cash generation. Against this backdrop, the company's fundamentals grade moves up from D to C. Our model value has climbed sharply, from $59.87 to $190 a share, a gap that stands in stark contrast to the current share price of $51.48.

Where Ultra Clean stands after its latest 10-Q

Operating margin widened to 2.8% from -3.6%. Against its peers on growth, profitability, cash generation and balance sheet, it grades D. It passes 2 of our 7 financial-health checks. Our revenue-to-maturity cash-flow model value is $59.87 a share, against a share price of $47.35.

Valuation models

We value Ultra Clean Holdings, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 12.9%: the 10-year Treasury yield (4.9%) plus a beta of 1.77 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Growth cash-flow model Revenue for this year and next from analysts' consensus, then growth fading to 2.5%; the operating margin moving to profitable peers'; investment needed per dollar of growth from peers; reduced by a failure probability. For young or fast-growing companies. The starting margin is normalized to between -100% and 60%; net margin is a proxy when operating income is not tagged. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$210 ~$120–$290 Primary model, counts double
Forward price-to-earnings vs peers Next year's consensus earnings per share times peers' typical (harmonic-mean) forward price-to-earnings. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$110 ~$100–$140 Included
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. ~$1.7 ~$1.1–$2.7 Left out: out of range vs price (0.04x)
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. — Does not apply: return on equity is not positive
Forward price-to-sales vs peers Next year's consensus sales per share times peers' typical forward price-to-sales; only when earnings are negative. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$330 ~$230–$550 Left out: out of range vs price (6.96x)
Revenue-to-maturity model Revenue grown to maturity with the cash margin moving to the industry's; for companies not yet profitable. ~$140 ~$110–$180 Included
Combined value Weighted average of the models that apply: the primary model (growth cash-flow model) counts double. Models more than 5x or less than 0.2x the share price, or more than 3x away from the other models' median, are left out. ~$170 ~$110–$210 3 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Ultra Clean Holdings, Inc. with Semiconductor Materials & Equipment in our coverage, using third-party market data.

Free cash flow is cash from operations minus capital spending. Growth is left blank when last year's figure was a loss or under 2% of revenue. Share counts and EPS are restated for stock splits. A dash means the company didn't report the figure.
