Two share counts disagree (259.67M in the company's Sep 22, 2026 report, 145.10M 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 129.28%; nothing is left for Other.
