WSTWest Pharmaceutical Services
Is the business good?
The checks split: 7 of 9 health tests passed and earnings fully cash-backed (1.2×), but margins compressing.
High fundamental quality. 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.
Margin-driven, fat margins on slower asset turns. ROE 17% = margin × turnover × leverage.
Unless marked, from derived.
