* 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 ($1.2k this quarter). Holder counts are more reliable. Shares outstanding: 38.4m as of 2026-03-01, 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 ≈ $11.92. Options: 9 managers hold calls ($12.9m notional), 8 hold puts ($5.4m).
