* 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 ($634.5k this quarter). Holder counts are more reliable. Shares outstanding: 19.4m as of 2025-07-16, from the company's own SEC filing; the percentage can still exceed 100%: lent-out shares are counted by the lender and the buyer, and some reports overlap without saying so. Implied quarter-end price ≈ $37.21. Options: 4 managers hold calls ($4.3m notional), 2 hold puts ($543.3k).
