* 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 ($140.6k this quarter). Holder counts are more reliable. Shares outstanding: 18.2m as of 2026-07-31, 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 ≈ $52.71. Options: 2 managers hold calls ($353.0k notional), 0 hold puts (—).
