Comscore updates major shareholder ownership filing

Rhea-AI Filing Summary

COMSCORE, INC. (symbol: SCOR) is the issuer of record for a Form SCHEDULE 13D/A filing submitted to the SEC.

Filing Explained

Completed on August 19, 2026, Charter's acquisition of Liberty Broadband left Liberty with zero comScore shares and ended its above-5% ownership filing.

Liberty Broadband reports that its acquisition by Charter completed on August 19, 2026; Liberty therefore ceased to beneficially own any comScore common stock or Series C Preferred Stock.

Schedules 13D and 13G disclose beneficial ownership above 5%; the supplied definition describes 13D as applying when a holder may seek to influence control and 13G as applying to passive holders.

This Amendment No. 4 is identified as Liberty's final amendment and exit filing, and the filing reports that Liberty ceased to be a beneficial owner of more than 5% of comScore's outstanding common stock.

As of August 19, 2026, Liberty reported zero shares, zero sole or shared voting power, zero sole or shared dispositive power, and 0.00% of the class.
