Represents (i) 3,295,183 shares of common stock, par value $0.001 per share ("Common Stock"), (ii) 61,431 shares of Common Stock, issuable upon settlement of deferred restricted stock units ("RSUs"), (iii) 4,223,621 shares of Common Stock issuable upon conversion of 4,223,621 shares of Series C Convertible Preferred Stock, par value $0.001 ("Series C Preferred Stock"), (iv) 3,286,825 shares of Common Stock that were acquired in connection with the Combination (as defined and disclosed in Item 4) and (v) 4,223,621 shares of Common Stock issuable upon conversion of 4,223,621 shares of Series C Preferred Stock that were acquired in connection with the Combination. Such shares of Common Stock represent approximately 63.7% of the Issuer's outstanding Common Stock, assuming settlement of the deferred RSUs held by the Reporting Persons and the exchange of all Series C Preferred Stock held by the Reporting Persons into shares of Common Stock, in accordance with Rule 13d-3 of the Act. However, pursuant to the Certificate of Designations of Series C Convertible Preferred Stock (the ''Certificate of Designations''), no holder of Series C Preferred Stock may convert Series C Preferred Stock in an amount that would cause such holder to beneficially own immediately following such conversion more than 49.99% of the then outstanding shares of Common Stock. Pursuant to the Certificate of Designations, to the extent that the Series C Preferred Stock and any shares of Common Stock held by the Reporting Person, together with certain transferees and affiliates, would represent voting rights with respect to more than 33.32% of the Common Stock (including the Series C Preferred Stock on an as-converted basis) (the ''Voting Threshold''), such Reporting Person will not be permitted to exercise the voting rights with respect to any shares of Series C Preferred Stock held by them in excess of the Voting Threshold and the Issuer shall exercise the voting rights with respect to such shares of Series C Preferred Stock in excess of the Voting Threshold in a neutral manner. Calculated based on 15,184,326 shares of Common Stock outstanding as of August 10, 2026, as reported on comScore, Inc.'s (the "Issuer") 10-Q filed with the Securities and Exchange Commission ("SEC") on August 14, 2026, as increased by (i) 61,431 shares of Common Stock issuable upon settlement of deferred RSUs held by the Reporting Persons (as defined in Item 5), (ii) 4,223,621 shares of Common Stock issuable upon conversion of 4,223,621 shares of Series C Preferred Stock, and (iii) (v) 4,223,621 shares of Common Stock issuable upon conversion of 4,223,621 shares of Series C Preferred Stock that were acquired in connection with the Combination.

The information set forth in Item 4 of this Statement is incorporated herein by reference.

Item 4.

Purpose of Transaction

The information set forth in Item 4 of the Schedule 13D is amended to incorporate the following at the end thereof: On August 19, 2026, Charter Communications, Inc., a Delaware corporation ("Charter Parent"), completed its previously announced acquisition of Liberty Broadband Corporation, a Delaware corporation ("Liberty"), pursuant to that certain Agreement and Plan of Merger, dated as of November 12, 2024 (the "Merger Agreement"), by and among Charter Parent, Fusion Merger Sub 1, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Charter Parent ("Merger LLC"), Fusion Merger Sub 2, Inc., a Delaware corporation and a direct wholly owned subsidiary of Merger LLC ("Merger Sub"), pursuant to which (i) Merger Sub merged with and into Liberty (the "Merger"), with Liberty surviving the Merger as the surviving corporation and a wholly owned subsidiary of Merger LLC, and (ii) immediately following the Merger, Liberty (as the surviving corporation in the Merger) merged with and into Merger LLC (the "Upstream Merger", and together with the Merger, the "Combination"), with Merger LLC surviving the Upstream Merger as the surviving company and a wholly owned subsidiary of Charter Parent. In connection with the completion of the Combination, Charter Parent became the beneficial owner of 3,286,825 shares of Common Stock held by Liberty and 4,223,621 shares of Common Stock issuable upon conversion of 4,223,621 shares of Series C Preferred Stock held by Liberty.

Item 5.

Interest in Securities of the Issuer

(a)

The information contained on the cover pages of this Statement and the information set forth in Item 4 of this Statement are incorporated herein by reference. As of the date hereof, the Reporting Persons (as defined in Item 5(b)) beneficially own an aggregate of 15,090,681 shares of Common Stock, inclusive of 8,447,242 shares of Common Stock issuable upon conversion of 8,447,242 shares of Series C Preferred Stock, 6,582,008 shares of Common Stock and 61,431 shares of Common Stock issuable in respect of deferred RSUs. Such shares of Common Stock represent approximately 63.7% of the Issuer's outstanding Common Stock, assuming settlement of the deferred RSUs held by the Reporting Persons and the exchange of all Series C Preferred Stock held by the Reporting Persons into shares of Common Stock, in accordance with Rule 13d-3 of the Act. However, pursuant to the Certificate of Designations, no holder of Series C Preferred Stock may convert Series C Preferred Stock in an amount that would cause such holder to beneficially own immediately following such conversion more than 49.99% of the then outstanding shares of Common Stock. Pursuant to the Certificate of Designations, to the extent that the Series C Preferred Stock and any shares of Common Stock held by the Reporting Person, together with certain transferees and affiliates, would represent voting rights with respect to more than the Voting Threshold, such Reporting Person will not be permitted to exercise the voting rights with respect to any shares of Series C Preferred Stock held by them in excess of the Voting Threshold and the Issuer shall exercise the voting rights with respect to such shares of Series C Preferred Stock in excess of the Voting Threshold in a neutral manner. In addition, the Reporting Persons may, as a result of the Second Amended and Restated Stockholders Agreement (as defined and disclosed in Item 6 of this Statement) and certain rights and agreements thereunder, be deemed to be part of a group with the other shareholder parties thereto. Such group would beneficially own an aggregate of 22,715,781 shares of Common Stock, representing approximately 81.36% of the Issuer's outstanding Common Stock, provided that the Reporting Persons disclaim, and this filing shall not be deemed an admission of, the existence of or membership in any such group.

(b)

Charter Communications Holding Company, LLC, a Delaware limited liability company ("Charter Holdco") is the beneficial owner of the 6,582,008 shares of Common Stock and 8,447,242 shares of Series C Preferred Stock and has the right to receive 61,431 shares of Common Stock to be issued in settlement of deferred RSUs granted by the Issuer in respect of David Kline's and Jeffrey Barratt Murphy's service on the Issuer's board of directors. Spectrum Management Holding Company, a Delaware limited liability company ("Spectrum Holdings"), is the controlling parent company of Charter Holdco. Charter Communications Holdings, LLC, a Delaware limited liability company ("Charter Holdings"), is the controlling parent company of Spectrum Holdings. CCH II, LLC, a Delaware limited liability company ("CCH II"), is the controlling parent company of Charter Holdings. Charter Parent is the controlling parent company of CCH II. As a result of the foregoing ownership and relationships, each of Charter Parent, Charter Holdco, CCH II, Charter Holdings and Spectrum Holdings may be deemed to have shared power to vote and dispose or direct the vote and direct the disposition of the reported securities held by Charter Holdco (subject, in each case, to the limitations on the conversion and voting of Series C Preferred Stock as further described herein). Charter Parent, Charter Holdco, CCH II, Charter Holdings and Spectrum Holdings are sometimes referred to herein collectively as the "Reporting Persons" and individually as a "Reporting Person." Neither the filing of this Statement nor any of its contents shall be deemed to constitute an admission by any of the Reporting Persons that it is the beneficial owner of any of the Common Stock referred to herein for the purposes of Section 13(d) of the Act, or for any other purpose, and such beneficial ownership (other than Series C Preferred Stock and Common Stock held directly by such Reporting Person) is expressly disclaimed by each such Reporting Person.

(c)
