What the filings flag
-140%Return on invested capital.Return on invested capital is -140% and slipping from -22% — well below its ~9% cost of capital, so reinvested dollars may be destroying value, not building it.
+36.4%/yrShare-count dilution.Diluted share count changed +109% over the last 3 years to FY2025 (+36.4%/yr). The count is GROWING — existing holders are being diluted. That's ~36.4% 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 ~109%.
