* 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 ($88.9k this quarter). Holder counts are more reliable. Shares outstanding: 52.8m as of 2025-08-06, 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 ≈ $3.73. Options: 5 managers hold calls ($449.4k notional), 1 hold puts ($0).
