What the filings flag
119d DSOReceivables vs revenue.Days sales outstanding moved from 84 to 119 days FY2024→FY2025 (receivables +325% vs revenue +202%). Receivables are outrunning sales — a flag for aggressive revenue recognition or slipping collections.
-76%Return on invested capital.Return on invested capital is -76% and rising from -217% — well below its ~9% cost of capital, so reinvested dollars may be destroying value, not building it.
+24.9%/yrShare-count dilution.Diluted share count changed +75% over the last 3 years to FY2025 (+24.9%/yr). The count is GROWING — existing holders are being diluted. That's ~24.9% 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 ~75%.
