What the filings flag
153dInventory days.Days inventory outstanding moved from 106 to 153 FY2024→FY2025 (against cost of goods sold; inventory +13% vs -22% in cost of sales). Inventory is outrunning what's being sold — a flag for softening demand or obsolescence risk ahead.
-124%Return on invested capital.Return on invested capital is -124% and slipping from -102% — well below its ~10% cost of capital, so reinvested dollars may be destroying value, not building it.
+2036.1%/yrShare-count dilution.Diluted share count changed +2036% over the last 1 years to FY2025 (+2036.1%/yr). The count is GROWING — existing holders are being diluted. That's ~2036.1% 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 FY2024 has been diluted ~2036%.
