Two share counts disagree (168.81M in the company's Sep 3, 2026 report, 136.44M 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 121.85%; nothing is left for Other.
