Two share counts disagree (43.01M in the company's Sep 23, 2026 report, 38.45M elsewhere); stakes use the report.
This quarter's institutional total failed a plausibility check; shown: the largest filers plus last quarter's remainder.
A stock split fell inside the quarter, so quarter-on-quarter changes are not shown.
These groups come from separate filings that can overlap, so they add to 146.21%; nothing is left for Other.
This company has 2 share classes; every stake here is a share of the whole company.
