LFUSLittelfuse, Inc.
Is the business good?
The checks split: earnings fully cash-backed (8.3×), but margins compressing.
Mixed fundamental signals. Nine pass/fail tests of year-over-year health from the filings.
Operating profit is fully backed by cash. Conversion is improving vs a year ago.
Operating profit is falling even as sales grow, costs are outrunning the top line.
Where this answer is blind. The F-score rewards improvement, so an already-elite company can score mid-pack.
