Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business OUTFRONT Media Inc. (the “Company”) and its subsidiaries (collectively, “we,” “us” or “our”) is a real estate investment trust (“REIT”), which provides advertising space (“displays”) on out-of-home advertising structures and sites in the United States (the “U.S.”). Our inventory consists of billboard displays, which are primarily located on the most heavily traveled highways and roadways in top Nielsen Designated Market Areas (“DMAs”), and transit advertising displays operated under exclusive multi-year contracts with municipalities in large cities across the U.S. In total, we have displays in approximately 120 markets across the U.S., including the 25 largest markets in the U.S. We currently manage our operations through two reportable operating segments—(1) Billboard and (2) Transit. Prior to its sale, our Canadian operations comprised our International operating segment, which did not meet the criteria to be a reportable segment and accordingly, was included in Other. Historical operating results of our Canadian operations are included in Other through the date of sale. On June 7, 2024, we sold all of our equity interests in Outdoor Systems Americas ULC and its subsidiaries (the “Transaction”), which held all of the assets of the Company’s outdoor advertising business in Canada (the “Canadian Business”). (See Note 13. Acquisitions and Dispositions: Dispositions.) Basis of Presentation and Use of Estimates The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (the “SEC”). In the opinion of our management, the accompanying unaudited consolidated financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation of our financial position, results of operations and cash flows for the periods presented. These financial statements should be read in conjunction with the more detailed financial statements and notes thereto, included in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025. The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amount of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. On January 17, 2025, the Company effected a Reverse Stock Split (as defined below) of the Company’s common stock (see Note 10. Equity). All shares of the Company’s common stock and per-share data included in these consolidated financial statements have been retroactively adjusted as though the Reverse Stock Split has been effected prior to all periods presented.
