UCTTUltra Clean Holdings, Inc.
Is the business good?
More warning than reassurance: profits without cash flow and margins compressing.
Mixed fundamental signals. Nine pass/fail tests of year-over-year health from the filings.
Reports an operating profit but operating cash flow is negative, a red flag.
Positive operating leverage, operating profit is growing faster than sales, so margins widen as the business scales.

Percentile against every name Ryufin tracks. Higher is better; the tick marks the middle of the market. Context, not one of the checks above.
Where this answer is blind. The F-score rewards improvement, so an already-elite company can score mid-pack.
