* 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 ($1.9m this quarter). Holder counts are more reliable. Shares outstanding: 27.6m as of 2025-05-07, 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 ≈ $13.51. Options: 4 managers hold calls ($2.2m notional), 1 hold puts ($0).
