* 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 ($6.1m this quarter). Holder counts are more reliable. Shares outstanding: 45.9m as of 2026-05-29, 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 ≈ $18.59. Options: 1 managers hold calls ($3.7k notional), 1 hold puts ($186.2k).
