* 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 ($726 this quarter). Holder counts are more reliable. Shares outstanding: 13.3m as of 2025-08-05, 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 ≈ $7.81. Options: 4 managers hold calls ($139.8k notional), 2 hold puts ($30.0k).
