* 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 ($17.6k this quarter). Holder counts are more reliable. Shares outstanding: 32.7m as of 2026-08-04, 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 ≈ $6.47. Options: 5 managers hold calls ($1.1m notional), 3 hold puts ($430.9k).
