March 25, 2026

comScore, Inc.

11950 Democracy Drive, Suite 600

Reston, Virginia 20190

Ladies and Gentlemen:

We have acted as counsel for comScore, Inc., a Delaware corporation (the "<u>Company"</u>), in connection with the Company's registration under the Securities Act of 1933, as amended (the "<u>Act</u>"), of the offer and sale of an additional 2,000,000 shares of the Company's common stock, par value $0.001 per share (the "<u>Shares</u>"), pursuant to the Company's registration statement on Form S-8 (the "<u>Registration Statement</u>") to be filed with the Securities and Exchange Commission on March 25, 2026, which Shares may be issued from time to time in accordance with the terms of the comScore, Inc. Amended and Restated 2018 Equity and Incentive Compensation Plan (as amended from time to time, the "<u>Plan</u>").

In reaching the opinions set forth herein, we have examined and are familiar with originals or copies, certified or otherwise identified to our satisfaction, of such documents and records of the Company and such statutes, regulations and other instruments as we deemed necessary or advisable for purposes of this opinion, including (i) the Registration Statement, (ii) certain resolutions adopted by the board of directors of the Company, (iii) the Plan, and (iv) such other certificates, instruments, and documents as we have considered necessary for purposes of this opinion. As to any facts material to our opinions, we have made no independent investigation or verification of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Company.

We have assumed (i) the legal capacity of all natural persons, (ii) the genuineness of all signatures, (iii) the authority of all persons signing all documents submitted to us on behalf of the parties to such documents, (iv) the authenticity of all documents submitted to us as originals, (v) the conformity to authentic original documents of all documents submitted to us as copies, (vi) that all information contained in all documents reviewed by us is true, correct and complete, and (vii) that the Shares will be issued in accordance with the terms of the Plan.

Based on the foregoing and subject to the limitations set forth herein, and having due regard for the legal considerations we deem relevant, we are of the opinion that the Shares have been duly authorized and, when the Shares are issued by the Company in accordance with the terms of the Plan and the instruments executed pursuant to the Plan, as applicable, the Shares will be validly issued, fully paid and nonassessable.

This opinion is limited in all respects to the General Corporation Law of the State of Delaware.
