* 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 ($1.2m this quarter). Holder counts are more reliable. Shares outstanding: 56.5m as of 2026-07-31, 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 ≈ $6.63. Options: 5 managers hold calls ($2.9m notional), 1 hold puts ($5.3k).

Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.
