What the filings flag
60d DSOReceivables vs revenue.Days sales outstanding moved from 44 to 60 days FY2024→FY2025 (receivables +44% vs revenue +8%). Receivables are outrunning sales — a flag for aggressive revenue recognition or slipping collections.
-27%Return on invested capital.Return on invested capital is -27% and slipping from -10% — well below its ~10% cost of capital, so reinvested dollars may be destroying value, not building it.
+1.6%/yrShare-count dilution.Diluted share count changed +5% over the last 3 years to FY2025 (+1.6%/yr). The count is GROWING — existing holders are being diluted. That's ~1.6% 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 ~5%.
stoppedShareholder returns — halted.Capital returns have STOPPED — $30M of buybacks + dividends in FY2024, but ~$0 in FY2025. A halt usually means the company is conserving cash; understand why before reading it as neutral.
