COMSCORE INC

* Summed across managers.

Holder counts are more reliable. Implied quarter-end price ≈ $1.22. Options: 3 managers hold calls ($6.8k notional), 3 hold puts ($123).

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.
