* 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 ($653.9k this quarter). Holder counts are more reliable. Shares outstanding: 71.7m as of 2025-10-31, 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 ≈ $2.42. Options: 2 managers hold calls ($59.8k notional), 3 hold puts ($35.6k).
