Two share counts disagree (35.43M in the company's Sep 22, 2026 report, 32.69M 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 107.87%; nothing is left for Other.
