* 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 ($1.1m this quarter). Holder counts are more reliable. Shares outstanding: 159.7m as of 2026-07-20, 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 ≈ $6.35. Options: 11 managers hold calls ($10.4m notional), 8 hold puts ($1.8m).
