Explanation of Responses:

( 1 )Each restricted stock unit represents a contingent right to receive one share of the Company's common stock. ( 2 )The number of shares subject to this restricted stock unit award was determined by dividing $42,500 by $15.83, which was the price per share used for the Company's most recent employee equity awards. ( 3 )This restricted stock unit award (the "Stock Award") was granted pursuant to the terms of the comScore, Inc. 2018 Equity and Incentive Compensation Plan. This award, which represents prorated compensation for the 2023-2024 director term for Jeffrey Barratt Murphy, will vest in full on the earliest of (i) the date of the Company's 2024 annual meeting of stockholders, (ii) June 30, 2024, and (iii) the date of a change in control of the Company, subject in each case to Mr. Murphy's continued status as a member of the Company's Board of Directors on the vesting date. Vested units will be deferred and delivered in shares of common stock upon a separation from service or a change in control of the Company, as set forth in the applicable award notice. ( 4 )Restricted Stock Units (8,415) which were issued to Pierre-Andre Liduena were cancelled in connection with his resignation from the Board of Directors of comScore, Inc. on April 1, 2024. The number of Restricted Stock Units beneficially owned has been updated to reflect the 1-for-20 reverse stock split effected 12/20/2023 as disclosed in the Company's Form 8-K dated 12/27/2023. ( 5 )David Kline, Pierre-Andre Liduena and Jeffrey Barratt Murphy each assigned all their rights and interests in Company equity awards, including the Stock Award, to Charter Communications Holding Company, LLC ("HoldCo"). Spectrum Management Holding Company, LLC ("Spectrum Management") is the controlling parent company of HoldCo. Charter Communications Holdings, LLC ("Holdings") is the controlling parent company of Spectrum Management. CCH II, LLC ("CCH II") is the controlling parent company of Holdings. Charter Communications, Inc. is the controlling parent company of CCH II.
