COPT DEFENSE PROPERTIES CDP
SHS BEN INT · REIT · CUSIP 22002T108
* 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 ($23.7m this quarter). Holder counts are more reliable. Shares outstanding: 113.4m 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 ≈ $36.02. Options: 2 managers hold calls ($4.8m notional), 2 hold puts ($1.1m).

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.
