State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

comScore, Inc. (“comScore” or the “Company”) is unable to file, without unreasonable effort and expense, its Quarterly Report on Form 10-Q for the quarter ended September 30, 2017 because it requires additional time to complete the preparation of its financial statements included therein, due to a previously disclosed internal investigation and restatement of certain financial statements of the Company. These matters were discussed in the Company’s Current Report on Form 8-K filed on September 15, 2016 (the “Restatement 8-K”) and subsequent filings.

PART IV

Quarterly Report on Form 10-Q for the quarter ended June 30, 2017

Quarterly Report on Form 10-Q for the quarter ended March 31, 2017

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

A discussion of the estimated effects of errors with respect to non-monetary transactions contributing to the need for a restatement of certain Company financial statements was set forth in Item 4.02 of the Restatement 8-K. The Company’s consolidated financial statements will reflect additional accounting adjustments in addition to those described in the Restatement 8-K that may arise as a result of the efforts described therein. At this time, the Company does not plan to provide further updates regarding any such additional adjustments until the consolidated financial statements are filed.

Forward-Looking Statements

This Form 12b-25 contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”), including, without limitation, comScore’s expectations as to the timing and outcome of its restatement of certain of its financial statements and the filing of the related quarterly and annual reports (the “Reports”).

These forward-looking statements involve risks and uncertainties, and actual results could vary materially from these forward-looking statements. Factors that may cause future results to differ materially from management’s current expectations include, among other things, the discovery of additional information relevant to the internal review; the conclusions of the Audit Committee (and the timing of the conclusions) concerning matters relating to the internal review; the timing of the review by, and the conclusions of, comScore’s independent registered public accounting firm regarding the internal review and comScore’s financial statements; the possibility that additional errors may be identified; the risk that the completion and filing of the Reports will take longer than expected; pending litigation and the possibility of further legal proceedings adverse to comScore resulting from the restatement or related matters; the costs associated with the restatement; and recent changes in comScore’s management. comScore disclaims any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or otherwise.
