Two share counts disagree (18.44M in the company's Sep 22, 2026 report, 26.88M elsewhere); stakes use the report.
This quarter's institutional total failed a plausibility check; shown: the largest filers plus last quarter's remainder.
These groups come from separate filings that can overlap, so they add to 108.39%; nothing is left for Other.
