What the filings flag
-36%Return on invested capital.Return on invested capital is -36% and rising from -80% — well below its ~9% cost of capital, so reinvested dollars may be destroying value, not building it.
+4.7%/yrShare-count dilution.Diluted share count changed +14% over the last 3 years to FY2025 (+4.7%/yr). The count is GROWING — existing holders are being diluted. That's ~4.7% shaved off per-share growth every year — total profit has to grow that much just to keep earnings-per-share flat, and a stake held since FY2022 has been diluted ~14%.
74d DSOReceivables vs revenue.Days sales outstanding moved from 68 to 74 days FY2024→FY2025 (receivables +28% vs revenue +18%). Receivables are creeping up relative to sales — watch the trend.
18% of revStock-based comp load.Stock-based compensation ran 18% of revenue in FY2025 — about $0.27 per diluted share. Meaningful — reported free cash flow flatters the economics, since SBC is a real cost paid in shares.
$41MGoodwill impairments.Took $41M of goodwill writedowns across 1 year(s) (FY2024 ($41M)). Writedowns mean past acquisitions underperformed what was paid for them — worth weighing on capital-allocation skill.
