* 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 ($15.6k this quarter). Holder counts are more reliable. Shares outstanding: 68.3m as of 2024-08-05, 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 ≈ $9.00. Options: 5 managers hold calls ($398.7k notional), 5 hold puts ($598.5k).

Major shareholders (over 5%)
