What the filings flag
-2%Return on invested capital.Return on invested capital is -2% and slipping from 8% — well below its ~9% cost of capital, so reinvested dollars may be destroying value, not building it.
60d DSOReceivables vs revenue.Days sales outstanding moved from 56 to 60 days FY2024→FY2025 (receivables +4% vs revenue -3%). Receivables are creeping up relative to sales — watch the trend.
68dInventory days.Days inventory outstanding moved from 59 to 68 FY2024→FY2025 (against cost of goods sold; inventory +12% vs -2% in cost of sales). Inventory is building a little faster than sales — watch for markdowns.
+0.1%/yrShare-count dilution.Diluted share count changed +0% over the last 3 years to FY2025 (+0.1%/yr). Roughly flat — buybacks are about offsetting stock comp, not shrinking the count. Per-share value isn't being meaningfully helped or hurt by the count.
$785MGoodwill impairments.Took $785M of goodwill writedowns across 1 year(s) (FY2025 ($785M)). Writedowns mean past acquisitions underperformed what was paid for them — worth weighing on capital-allocation skill.
