* 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 ($691.9k this quarter). Holder counts are more reliable. Shares outstanding: 22.0m as of 2025-03-18, 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 ≈ $7.06. Options: 2 managers hold calls ($2.0k notional), 3 hold puts ($17.5k).
