* 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 ($903.2k this quarter). Holder counts are more reliable. Shares outstanding: 104.9m as of 2025-12-31, 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 ≈ $3.56. Options: 13 managers hold calls ($6.3m notional), 14 hold puts ($6.6m).
