Two share counts disagree (7.64M in the company's Sep 23, 2026 report, 9.79M 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 122.71%; nothing is left for Other.
