Q1 2025 share counts are adjusted for a 3-for-1 stock split, so holders aren't shown as buying or selling because of it.

* Summed across managers. Shares that two managers' reports both contain – a subsidiary's holdings that its parent's report includes too, or a sub-adviser's in its client's – are counted once ($563.7k this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $35.71. Options: 8 managers hold calls ($39.1m notional), 8 hold puts ($21.8m).
