AMKRAmkor Technology, Inc.
Is the business good?
The checks split: nothing decisive, though earnings fully cash-backed (2.1×).
Mixed fundamental signals. Nine pass/fail tests of year-over-year health from the filings.
Operating profit is fully backed by cash. Conversion is worsening vs a year ago.
Positive operating leverage, operating profit is growing faster than sales, so margins widen as the business scales.
A balanced mix of margins, efficiency, and leverage. ROE 9% = margin × turnover × leverage.
Unless marked, from derived.
