* 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 ($2.4m this quarter). Holder counts are more reliable. Shares outstanding: 110.7m as of 2026-04-24, 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 ≈ $56.76. Options: 4 managers hold calls ($545.1k notional), 4 hold puts ($1.3m).
