We rate Ultra Clean Holdings, Inc. (UCTT) as a Hold with a composite score of 60.9/100 at a current price of $72.00. The stock presents a mixed quantitative picture — neither compelling enough to warrant new accumulation nor weak enough to justify selling for existing holders. Our factors are split, and the overall profile suggests patience is warranted.

The rating is primarily driven by strength in momentum (76th percentile) and value (65th percentile), which together account for the majority of the composite score. Offsetting weakness in stability (38th percentile) and investment (49th percentile) tempers our overall conviction. We assign a No Moat rating (28/100), Very High uncertainty, and Poor capital allocation.

Key items to watch: whether strong momentum is fundamentally supported by revenue trends; the path to profitability. Any material change in these dynamics could warrant a reassessment of our rating. The moat trend is stable, which suggests the competitive landscape is stable for now.

Ultra Clean Holdings, Inc. holds a top-quartile position (#0 of 50) within the Manufacturing sector, based on our composite quantitative scoring across quality, value, momentum, and stability factors. The composite score of 60.9/100 places it at rank #610 in our full 7,333-stock universe. At $1.2B in market capitalization, Ultra Clean Holdings, Inc. is a small-cap player in the Manufacturing space, which limits certain scale advantages but may allow for more agile strategic execution.

Despite positive momentum (76th percentile), revenue contraction of -1% creates a divergence between price action and fundamental trajectory. This divergence suggests either that the market is looking through near-term weakness or that technical factors are temporarily inflating the stock. Investors should assess whether the revenue decline reflects cyclical weakness or structural challenges.

The margin cascade tells an important story: gross margins of 16% (-26.3pp vs sector) narrow to operating margins of -5% (-5.8pp vs sector) and net margins of -8.2%, yielding a gross-to-net conversion rate of -51%. The significant margin erosion from gross to net suggests elevated operating expenses, high interest costs, or other structural drags that warrant monitoring.

At a current price of $72.00, Ultra Clean Holdings, Inc. is trading near fair value based on current fundamentals. Our value factor score of 65/100 reflects a composite assessment across multiple valuation metrics including price-to-earnings, price-to-book, EV/EBITDA, and price-to-sales ratios relative to both sector peers and the broader market. Valuation metrics are mixed, with no strong signal of mispricing in either direction.

The stock currently trades at EV/EBITDA of 24.2x (at a premium), P/B of 3.8x, P/S of 1.3x. We evaluate these multiples in the context of both absolute levels and sector-relative positioning to form our valuation view.

We assign a Very High uncertainty rating to Ultra Clean Holdings, Inc.. The stock exhibits multiple compounding risk factors: elevated market sensitivity (beta of 2.27), current negative profitability (net margin -8.2%), below-average price stability (38th percentile). The extreme uncertainty around future cash flows makes precise valuation difficult, and the range of outcomes is exceptionally wide. Only investors with high risk tolerance and extended time horizons should consider this name.

Specific risk factors that inform our assessment include: elevated market sensitivity (beta of 2.27); current negative profitability (net margin -8.2%); below-average price stability (38th percentile); the combination of leverage (67% D/E) and thin margins (-8.2% net) amplifies downside risk. Each of these factors independently widens the distribution of potential outcomes, and in combination they create a risk profile that demands careful position sizing. The stability factor at the 38th percentile and quality factor at the 51th percentile provide a quantitative summary of the overall risk landscape.

We identify limited risk mitigants at this time, which contributes to our very high uncertainty assessment. Investors should monitor for improvement in balance sheet metrics, margin stability, and business predictability that could warrant a downgrade in our risk assessment over time.

We rate Ultra Clean Holdings, Inc.'s capital allocation as Poor. Key concerns include low returns on equity (-24.1%), negative profitability, weak asset returns (ROA -9.9%). Exemplary capital allocators generate ROE above 20% and maintain conservative leverage — Ultra Clean Holdings, Inc. significantly underperforms these benchmarks, raising questions about management's ability to create shareholder value.

Investors should scrutinize management's reinvestment decisions and balance sheet trajectory before committing capital. Poor capital allocation often compounds over time: overlevered balance sheets limit strategic flexibility, while low returns on capital destroy shareholder value. We would need to see sustained improvement in profitability metrics and balance sheet discipline before considering an upgrade.

In summary, Ultra Clean Holdings, Inc. receives a Hold rating with a composite score of 60.9/100 (rank #610 of 7,333). Our quantitative framework assigns a No Moat (28/100, trend: stable), Very High uncertainty, and Poor capital allocation. The average factor score across quality, value, momentum, stability, and investment is 56/100.

Our analysis supports a neutral stance on Ultra Clean Holdings, Inc.. While the quantitative profile is not weak enough to warrant selling, it lacks the multi-factor strength required for a buy recommendation. Existing holders should maintain positions and monitor for catalysts — either fundamental improvement or valuation compression — that would shift the risk-reward balance.
