Comscore (SCOR) 10% Owner Liberty Broadband Disposes & Acquires Shares

What Happened
Liberty Broadband Corp., reported as a 10% owner of Comscore (SCOR), recorded two non-market transactions on August 19, 2026 tied to a corporate combination. The Form 4 shows Liberty Broadband disposed of 3,286,825 shares (code J, price N/A) and acquired 4,223,621 derivative shares (code J, price N/A). No cash prices or market values are reported because these were merger-related transfers rather than open-market trades.

Key Details

• Transaction date: August 19, 2026; Form 4 filed August 21, 2026 (timely filing).
• Disposition: 3,286,825 shares (other disposition, code J), price N/A.
• Acquisition: 4,223,621 derivative shares (other acquisition, code J), price N/A. Footnote indicates the acquired instrument is Series C Convertible Preferred Stock convertible into ~4.223M common shares (originally 1:1 conversion rate).
• Post-transaction status: As a result of the Combination, Charter became the beneficial owner of the shares previously held by Liberty Broadband and Liberty Broadband ceased to be subject to Section 16 reporting obligations for Comscore (per filing footnote).
• Filing timeliness: Filed two days after the reported transaction date (not flagged as late).

Context
These entries arise from the Merger/Upstream Merger described in the filing (Charter’s acquisition of the reporting person), not from open-market buying or selling by an executive. The “acquired” line represents a derivative security (Series C preferred convertible into common stock at the holder’s option); it is not a purchase that signals direct market conviction in the usual sense. Because Liberty Broadband is a 10% institutional owner and the changes resulted from the corporate combination, this filing documents a transfer of ownership/control rather than typical insider trading.
