* 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 ($2.0m this quarter). Holder counts are more reliable. Shares outstanding: 73.1m as of 2025-07-31, 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 ≈ $3.00. Options: 2 managers hold calls ($1.0k notional), 2 hold puts ($3.9k).
