* 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. Holder counts are more reliable. Shares outstanding: 19.6m as of 2023-02-14, 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 ≈ $3.88. Options: 4 managers hold calls ($99.5k notional), 2 hold puts ($3.9k).

Major shareholders (over 5%)

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