* 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 ($107.1k this quarter). Holder counts are more reliable. Shares outstanding: 13.2m as of 2026-08-05, 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 ≈ $9.05. Options: 2 managers hold calls ($4.6m notional), 2 hold puts ($411.8k).
