* 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: 27.6m as of 2024-07-26, 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 ≈ $13.49. Options: 2 managers hold calls ($122.8k notional), 5 hold puts ($681.2k).

Major shareholders (over 5%)

Anyone who owns more than 5% of a class of the company's shares has to say so: on Schedule 13D if they may try to influence or control the company, on 13G if they're a passive investor, and update it as the stake changes. Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.

The acquisition of shares of Common Stock resulting from the vesting of the PRSUs, caused Mr. Gellert to exceed 5% beneficial ownership in the Issuer. On March 11, 2022, Mr. Gellert was granted 58,905 PRSUs consisting of five equal tranches, each of which would be earned if and when the closing price of one share of Common Stock equals or exceeds the specified stock price performance goal for such tranche for 60 consecutive trading days during the three year performance period beginning on the grant date, provided that any earned PRSUs would not be settled until the third anniversary of the grant date, subject to satisfaction of the service-base… Full filing
