Organization, Consolidation and Presentation of Financial Statements [Abstract]
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.”) and Canada. 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. and Canada. In total, we have displays in all of the 25 largest markets in the U.S. and approximately 150 markets across the U.S. and Canada. We currently manage our operations through two operating segments—U.S. Billboard and Transit, which is included in our U.S. Media reportable segment, and International. 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 statement 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, 2022, filed with the SEC on February 23, 2023. 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, including the impact of events such as the COVID-19 pandemic and the current heightened levels of inflation, 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. Out-of-Period Adjustment

Accounting Standards Update and Change in Accounting Principle [Abstract]
New Accounting Standards	New Accounting Standards Adoption of New Accounting Standards In the first quarter of 2023, we adopted the Financial Accounting Standards Board’s (the “FASB”) guidance on the recognition and measurement of contract assets and contract liabilities acquired in a business combination. At the acquisition date, the acquirer should account for the related revenue contracts as if it had originated the contracts. The guidance also provides certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. We will implement this guidance when accounting for business combinations in the future. Recent Pronouncements In March 2020 and December 2022, the FASB issued guidance providing optional expedients and exceptions for accounting for contracts, hedging relationships and other transactions that reference to the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform, if certain criteria are met. The guidance is

Goodwill and Intangible Assets Disclosure [Abstract]
Long-Lived Assets	Long-Lived Assets By the end of the first half of 2023, our U.S. Transit and Other reporting unit did not meet revenue expectations and as of June 30, 2023, our revenue pacing and outlook for the remainder of 2023 reflects a continued decline in transit revenues as compared to our 2023 forecast due to underperformance across our transit business, including the New York Metropolitan Transportation Authority (the “MTA”) transit system. As a result, in the second quarter of 2023, we determined that there was a decline in the long-term outlook for our U.S. Transit and Other reporting unit constituting a triggering event, which required an interim impairment analysis of goodwill and long-lived assets. Goodwill For the nine months ended September 30, 2023, and the year ended December 31, 2022, the changes in the book value of goodwill by segment were as follows: (in millions) U.S. Media Other Total As of December 31, 2021 $ 2,054.0 $ 23.8 $ 2,077.8 Currency translation adjustments — (1.4) (1.4) As of December 31, 2022 $ 2,054.0 $ 22.4 $ 2,076.4 Currency translation adjustments — 0.1 0.1 Impairment (47.6) — (47.6) As of September 30, 2023 $ 2,006.4 $ 22.5 $ 2,028.9 The estimated fair value of our U.S. Transit and Other reporting unit exceeded its carrying value by 28% as of December 31, 2022, based on our goodwill impairment assessment in the prior year. As a result of the impairment analysis performed during the second quarter of 2023, we determined that the carrying value of our U.S. Transit and Other reporting unit exceeded its fair value and we recorded an impairment charge of $47.6 million in the Consolidated Statements of Operations. As of September 30, 2023, the goodwill balances associated with the U.S. Billboard reporting unit was $2,006.4 million and the Canada reporting unit was $22.5 million. Intangible Assets Our identifiable intangible assets primarily consist of acquired permits and leasehold agreements, and franchise agreements, which grant us the right to operate out-of-home structures in specified locations and the right to provide advertising space on railroad and municipal transit properties. Identifiable intangible assets are amortized on a straight-line basis over their estimated useful life, which is the respective life of the agreement that in some cases includes historical experience of renewals. Our identifiable intangible assets consist of the following: (in millions) Gross Accumulated Amortization Impairment Net As of September 30, 2023: Permits and leasehold agreements $ 1,620.5 $ (916.1) $ — $ 704.4 Franchise agreements (a) 923.9 (424.1) (456.9) 42.9 Other intangible assets 21.0 (6.8) — 14.2 Total intangible assets $ 2,565.4 $ (1,347.0) $ (456.9) $ 761.5 As of December 31, 2022: Permits and leasehold agreements $ 1,597.6 $ (868.7) $ — $ 728.9 Franchise agreements 533.2 (418.6) — 114.6 Other intangible assets 18.9 (3.9) — 15.0 Total intangible assets $ 2,149.7 $ (1,291.2) $ — $ 858.5 (a) We reclassified all Prepaid MTA equipment deployment costs (see Note 16. Commitments and Contingencies ) and recorded impairments in the second and third quarters of 2023 due to a decline in the long-term outlook of our U.S. Transit and Other reporting unit. In the nine months ended September 30, 2023, we acquired approximately 440 displays, resulting in amortizable intangible assets for permits and leasehold agreements of $26.3 million, which are amortized using the straight-line method over their estimated useful lives, an average period of 15.4 years. All of our intangible assets, except goodwill, are subject to amortization. Amortization expense was $19.7 million in the three months ended September 30, 2023, $20.2 million in the three months ended September 30, 2022, $63.0 million in the nine months ended September 30, 2023, and $52.3 million in the nine months ended September 30, 2022. During the second quarter of 2023, we performed an analysis of the carrying value of our long-lived asset groups within our U.S. Transit and Other reporting unit as a result of the triggering event noted above utilizing undiscounted cash flows compared to the carrying value of the asset groups. As a result, we recorded an impairment charge of $463.5 million in the second quarter of 2023, primarily representing a $443.1 million impairment charge related to our MTA asset group. As a result of our continued expectation of negative aggregate cash flows related to our MTA asset group, we recorded an additional impairment charge of $12.1 million in the third quarter of 2023, representing additional MTA equipment deployment cost spending during the quarter.

Related Party Transactions	Related Party Transactions On January 18, 2023, we entered into a transaction with an affiliate of Providence Equity Partners L.L.C. (the “Providence Affiliate”) in connection with the Providence Affiliate’s purchase of a lease for certain outdoor advertising assets (the “Assets”) from a third-party seller. Pursuant to an agreement between us and the Providence Affiliate (the “Billboard Agreement”), we agreed to exclusively market, license and make advertising space available on the Assets to third-party advertisers for a term of up to ten years (the “Billboard Transaction”). In return, we will retain all revenues from the sale of advertising with respect to the Assets less the following payments to the Providence Affiliate or its payment designee, as applicable: (i) a minimum annual guarantee payment paid to the Providence Affiliate’s payment designee that increases from approximately $1.8 million to $3.5 million during the term of the Billboard Agreement; (ii) a minimum annual guarantee payment paid to the Providence Affiliate that increases from $8.5 million to $12.0 million by year six and adjusted for inflation thereafter through year ten; (iii) a percentage revenue share payment on gross revenues generated above $22.0 million paid to the Providence Affiliate during the term of the Billboard Agreement; (iv) a percentage revenue share payment on net revenues until $100.0 million is paid to the Providence Affiliate or its payment designee, as applicable; and (v) a one-time payment of $10.0 million paid to the Providence Affiliate on the fifth anniversary of the closing of the Billboard Transaction (the “Billboard Transaction Closing”) if we have not yet acquired the Assets as described below.

As of September 30, 2023, a discount of $1.1 million on the Term Loan remains unamortized. The discount is being amortized through Interest expense, net , on the Consolidated Statement of Operations. Revolving Credit Facility We also have a $500.0 million revolving credit facility, which matures in 2028 (the “Revolving Credit Facility,” together with the Term Loan, the “Senior Credit Facilities”). During the second quarter of 2023, the Company, along with its wholly-owned subsidiaries, Outfront Media Capital LLC (“Finance LLC”) and Outfront Media Capital Corporation (together with Finance LLC, the “Borrowers”), and the other guarantors party thereto, entered into two amendments (the “Amendments”) to the Credit Agreement (as defined below). The Amendments provide for (i) the replacement of the London Interbank Offered Rate with the Secured Overnight Financing Rate as the interest rate benchmark , (ii) the extension of the maturity date of the Revolving Credit Facility from its previous maturity date of November 18, 2024 to June 15, 2028, and (iii) an increase in the interest rate margins applicable to the Borrowers under the Revolving Credit Facility from a range of 1.25% to 1.75% to a range of 1.75% to 2.25%, in the case of Secured Overnight Financing Rate borrowings, based on the Borrowers’ leverage ratio. The Amendments also include springing maturity refinancing provisions with respect to the Borrowers’ outstanding term loan indebtedness and certain series of senior notes issued by the Borrowers, in each case, which have maturity dates prior to June 15, 2028, as well as other clarifying, conforming and ministerial changes to the Credit Agreement. As of September 30, 2023, there were no outstanding borrowings under the Revolving Credit Facility. The commitment fee based on the amount of unused commitments under the Revolving Credit Facility was $0.5 million in the three months ended September 30, 2023, $0.4 million in the three months ended September 30, 2022, $1.3 million in the nine months ended September 30, 2023, and $1.2 million in the nine months ended September 30, 2022. As of September 30, 2023, we had issued letters of credit totaling approximately $6.5 million against the letter of credit facility sublimit under the Revolving Credit Facility. Standalone Letter of Credit Facilities As of September 30, 2023, we had issued letters of credit totaling approximately $75.7 million under our aggregate $81.0 million standalone letter of credit facilities. The total fees under the letter of credit facilities were immaterial in each of the three and nine months ended September 30, 2023 and 2022. Accounts Receivable Securitization Facility As of September 30, 2023, we have a $150.0 million revolving accounts receivable securitization facility (the “AR Facility”), which terminates in May 2025, unless further extended. In connection with the AR Facility, Outfront Media LLC and Outfront Media Outernet Inc., each a wholly-owned subsidiary of the Company, and certain of the Company’s taxable REIT subsidiaries (“TRSs”) (the “Originators”), will sell and/or contribute their respective existing and future accounts receivable and certain related assets to either Outfront Media Receivables LLC, a special purpose vehicle and wholly-owned subsidiary of the Company relating to the Company’s qualified REIT subsidiary accounts receivable assets (the “QRS SPV”) or Outfront Media Receivables TRS, LLC a special purpose vehicle and wholly-owned subsidiary of the Company relating to the Company’s TRS accounts receivable assets (the “TRS SPV” and together with the QRS SPV, the “SPVs”). The SPVs may transfer undivided interests in their respective accounts receivable assets to certain purchasers from time to time (the “Purchasers”). The SPVs are separate legal entities with their own separate creditors who will be entitled to access the SPVs’ assets before the assets become available to the Company. Accordingly, the SPVs’ assets are not available to pay creditors of the Company or any of its subsidiaries, although collections from the receivables in excess of amounts required to repay the Purchasers and other creditors of the SPVs may be remitted to the Company. Outfront Media LLC will service the accounts receivables on behalf of the SPVs for a fee. The Company has agreed to guarantee the performance of the Originators and Outfront Media LLC, in its capacity as servicer, of their respective obligations under the agreements governing the AR Facility. Neither the Company, the Originators nor the SPVs guarantee the collectability of the receivables under the AR Facility. Further, the TRS SPV and the QRS SPV are jointly and severally liable for their respective obligations under the agreements governing the AR Facility. As of September 30, 2023, there were $150.0 million of outstanding borrowings under the AR Facility, at a borrowing rate of 6.4%. As of September 30, 2023, there is no borrowing capacity remaining under the AR Facility based on approximately $317.7 million of accounts receivable that could be used as collateral for the AR Facility in accordance with the agreements governing the AR Facility. The commitment fee based on the amount of unused commitments under the AR Facility was immaterial for the three months ended September 30, 2023, $0.1 million for the nine months ended September 30, 2023, and immaterial for each of the three and nine months ended September 30, 2022. As of November 2, 2023, there were $140.0 million of outstanding borrowings under the AR Facility, at a borrowing rate of 6.4%. Debt Covenants Our credit agreement, dated as of January 31, 2014 (as amended, restated, amended and restated, supplemented or otherwise modified, the “Credit Agreement”), governing the Senior Credit Facilities, the agreements governing the AR Facility, and the indentures governing our senior unsecured notes contain customary affirmative and negative covenants, subject to certain exceptions, including but not limited to those that restrict the Company’s and its subsidiaries’ abilities to (i) pay dividends on, repurchase or make distributions in respect to the Company’s or its wholly-owned subsidiary, Outfront Media Capital LLC’s capital stock or make other restricted payments other than dividends or distributions necessary for us to maintain our REIT status, subject to certain conditions and exceptions, (ii) enter into agreements restricting certain subsidiaries’ ability to pay dividends or make other intercompany or third-party transfers, and (iii) incur additional indebtedness. One of the exceptions to the restriction on our ability to incur additional indebtedness is satisfaction of a Consolidated Total Leverage Ratio, which is the ratio of our consolidated total debt to our Consolidated EBITDA (as defined in the Credit Agreement) for the trailing four consecutive quarters, of no greater than 6.0 to 1.0. As of September 30, 2023, our Consolidated Total Leverage Ratio was 5.2 to 1.0 in accordance with the Credit Agreement. The terms of the Credit Agreement (and under certain circumstances, the agreements governing the AR Facility) require that we maintain a Consolidated Net Secured Leverage Ratio, which is the ratio of (i) our consolidated secured debt (less up to $150.0 million of unrestricted cash) to (ii) our Consolidated EBITDA (as defined in the Credit Agreement) for the trailing four consecutive quarters, of no greater than 4.5 to 1.0. As of September 30, 2023, our Consolidated Net Secured Leverage Ratio was 1.1 to 1.0 in accordance with the Credit Agreement. As of September 30, 2023, we are in compliance with our debt covenants. Deferred Financing Costs As of September 30, 2023, we had deferred $24.1 million in fees and expenses associated with the Term Loan, Revolving Credit Facility, AR Facility and our senior unsecured notes. We are amortizing the deferred fees through Interest expense, net, on our Consolidated Statement of Operations over the respective terms of the Term Loan, Revolving Credit Facility, AR Facility and our senior unsecured notes.

The Series A Preferred Stock ranks senior to the shares of the Company’s common stock with respect to dividend and distribution rights. Holders of the Series A Preferred Stock are entitled to a cumulative dividend accruing at the initial rate of 7.0% per year, payable quarterly in arrears, subject to increases as set forth in the Articles Supplementary, effective as of April 20, 2020 (the “Articles”). Dividends may, at the option of the Company, be paid in cash, in-kind, through the issuance of additional shares of Series A Preferred Stock or a combination of cash and in-kind, until April 20, 2028, after which time dividends will be payable solely in cash. So long as any shares of Series A Preferred Stock remain outstanding, the Company may not, without the consent of a specified percentage of holders of shares of Series A Preferred Stock, declare a dividend on, or make any distributions relating to, capital stock that ranks junior to, or on a parity basis with, the Series A Preferred Stock, subject to certain exceptions, including but not limited to (i) any dividend or distribution in cash or capital stock of the Company on or in respect of the capital stock of the Company to the extent that such dividend or distribution is necessary to maintain the Company’s status as a REIT; and (ii) any dividend or distribution in cash in respect of our common stock that, together with the dividends or distributions during the 12-month period immediately preceding such dividend or distribution, is not in excess of 5% of the aggregate dividends or distributions paid by the Company necessary to maintain its REIT status during such 12-month period. If any dividends or distributions in respect of the shares of our common stock are paid in cash, the shares of Series A Preferred Stock will participate in the dividends or distributions on an as-converted basis up to the amount of their accrued dividend for such quarter, which amounts will reduce the dividends payable on the shares of Series A Preferred Stock dollar-for-dollar for such quarter. The Series A Preferred Stock is convertible at the option of any holder at any time into shares of our common stock at an initial conversion price of $16.00 per share and an initial conversion rate of 62.50 shares of our common stock per share of Series A Preferred Stock, subject to certain anti-dilution adjustments and a share cap as set forth in the Articles. Subject to certain conditions set forth in the Articles (including a change of control), each of the Company and the holders of the Series A Preferred Stock may convert or redeem the Series A Preferred Stock at the prices set forth in the Articles, plus any accrued and unpaid dividends. During the three months ended September 30, 2023, we paid cash dividends of $2.2 million on the Series A Preferred Stock and during the nine months ended September 30, 2023, we paid cash dividends of $6.6 million on the Series A Preferred Stock. As of September 30, 2023, the maximum number of shares of common stock that could be required to be issued on conversion of the outstanding shares of Series A Preferred Stock was approximately 7.8 million shares. We have a sales agreement in connection with an “at-the-market” equity offering program (the “ATM Program”), under which we may, from time to time, issue and sell shares of our common stock up to an aggregate offering price of $300.0 million. We have no obligation to sell any of our common stock under the sales agreement and may at any time suspend solicitations and offers under the sales agreement. No shares were sold under the ATM Program during the nine months ended September 30, 2023. As of September 30, 2023, we had approximately $232.5 million of capacity remaining under the ATM Program. On November 2, 2023, we announced that our board of directors approved a quarterly cash dividend of $0.30 per share on our common stock, payable on December 29, 2023, to stockholders of record at the close of business on December 1, 2023.

Income Taxes	Income Taxes We are organized in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) and, accordingly, we have not provided for U.S. federal income tax on our REIT taxable income that we distribute to our stockholders. We have elected to treat our subsidiaries that participate in certain non-REIT qualifying activities as TRSs. As such, we have provided for their federal, state and foreign income taxes. Tax years 2019 to present are open for examination by the tax authorities. Our effective income tax rate represents a combined annual effective tax rate for federal, state, local and foreign taxes applied to interim operating results.

Commitment and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Off-Balance Sheet Arrangements Our off-balance sheet commitments primarily consist of guaranteed minimum annual payments. These arrangements result from our normal course of business and represent obligations that are payable over several years. Contractual Obligations We have agreements with municipalities and transit operators which entitle us to operate advertising displays within their transit systems, including on the interior and exterior of rail and subway cars and buses, as well as on benches, transit shelters, street kiosks, and transit platforms. Under most of these franchise agreements, the franchisor is entitled to receive the greater of a percentage of the relevant revenues, net of agency fees, or a specified guaranteed minimum annual payment. Under the current MTA agreement, which was amended in June 2020 and July 2021 and is subject to modification as agreed-upon by us and the MTA (as amended, the “MTA Agreement”): • Deployments . We must deploy, over a number of years, (i) 5,433 digital advertising screens on subway and train platforms and entrances, (ii) 15,896 smaller-format digital advertising screens on rolling stock, and (iii) 9,283 MTA communications displays. We are also obligated to deploy certain additional digital advertising screens and MTA communications displays in subway and train stations and rolling stock that the MTA may build or acquire in the future (collectively, the “New Inventory”). • Recoupment of Equipment Deployment Costs. We may retain incremental revenues that exceed an annual base revenue amount for the cost of deploying advertising and communications displays throughout the transit system. As presented in the table below, recoupable MTA equipment deployment costs are recorded as Prepaid MTA equipment deployment costs and Intangible assets on our Consolidated Statement of Financial Position, and as these costs are recouped from incremental revenues that the MTA would otherwise be entitled to receive, Prepaid MTA equipment deployment costs will be reduced. If incremental revenues generated over the term of the agreement are not sufficient to cover all or a portion of the equipment deployment costs, the costs will not be recouped, which could have an adverse effect on our business, financial condition and results of operations, including impairment charges (see Note 4. Long-Lived Assets ). If we do not recoup all costs of deploying advertising and communications screens with respect to the New Inventory by the end of the term of the MTA Agreement, the MTA will be obligated to reimburse us for these costs. Deployment costs in an amount not to exceed $50.7 million, which are deemed authorized before December 31, 2020, will be paid directly by the MTA. For any deployment costs deemed authorized after December 31, 2020, the MTA and the Company will no longer be obligated to directly pay 70% and 30% of the costs, respectively, and these costs will be subject to recoupment in accordance with the MTA Agreement. We did not recoup any equipment deployment costs in the nine months ended September 30, 2023, and we do not expect to recoup any equipment deployment costs in the remainder of 2023. • Payments . We must pay to the MTA the greater of a percentage of revenues or a guaranteed minimum annual payment. Our payment obligations with respect to guaranteed minimum annual payment amounts owed to the MTA resumed on January 1, 2021, in accordance with the terms of the MTA Agreement, and any guaranteed minimum annual payment amounts that would have been paid for the period from April 1, 2020 through December 31, 2020 (less any revenue share amounts actually paid during this period using an increased revenue share percentage of 65%) will instead be added in equal increments to the guaranteed minimum annual payment amounts owed for the period from January 1, 2022, through December 31, 2026. The MTA Agreement also provides that if prior to April 1, 2028 the balance of unrecovered costs of deploying advertising and communications screens throughout the transit system is equal to or less than zero, then in any year following the year in which such recoupment occurs (the “Recoupment Year”), the MTA is entitled to receive an additional payment equal to 2.5% of the annual base revenue amount for such year calculated in accordance with the MTA Agreement, provided that gross revenues in such year (i) were at least equal to the gross revenues generated in the Recoupment Year, and (ii) did not decline by more than 5% from the prior year. • Term . In July 2021, we extended the initial 10-year term of the MTA Agreement to a 13-year base term (the “Amended Term”). We have the option to extend the Amended Term for an additional five-year period at the end of the Amended Term, subject to satisfying certain quantitative and qualitative conditions. During the nine months ended September 30, 2023, we had no recoupment from incremental revenues. As of September 30, 2023, 18,786 digital displays had been installed, composed of 5,117 digital advertising screens on subway and train platforms and entrances, 8,760 smaller-format digital advertising screens on rolling stock and 4,909 MTA communications displays. In the three months ended September 30, 2023, 2,028 installations occurred, for a total of 4,633 installations occurring in the nine months ended September 30, 2023. During the second quarter of 2023, we performed an analysis of the carrying value of our long-lived asset groups within our U.S. Transit and Other reporting unit as a result of the triggering event noted above utilizing undiscounted cash flows compared to the carrying value of the asset groups. As a result, we recorded an impairment charge of $463.5 million in the second quarter of 2023, primarily representing a $443.1 million impairment charge related to our MTA asset group. (See Note 4. Long-Lived Assets .) As a result of our continued expectation of negative aggregate cash flows related to our MTA asset group, we recorded an additional impairment charge of $12.1 million in the third quarter of 2023, representing additional MTA equipment deployment cost spending during the quarter.

As of September 30, 2023, the outstanding letters of credit were approximately $82.2 million and outstanding surety bonds were approximately $172.2 million, and were not recorded on the Consolidated Statements of Financial Position. Legal Matters On an ongoing basis, we are engaged in lawsuits and governmental proceedings and respond to various investigations, inquiries, notices and claims from national, state and local governmental and other authorities (collectively, “litigation”). Litigation is inherently uncertain and always difficult to predict. Although it is not possible to predict with certainty the eventual outcome of any litigation, in our opinion, none of our current litigation is expected to have a material adverse effect on our results of operations, financial position or cash flows.

Subsequent Events	Subsequent Event On October 22, 2023, the Company, Outfront Canada HoldCo 2 LLC, a wholly-owned subsidiary of the Company, and Outfront Canada Sub LLC, a wholly-owned subsidiary of the Company (together, the “Selling Subsidiaries”), entered into a Share Purchase Agreement (the “Share Purchase Agreement”) with Bell Media Inc. (the “Buyer”), relating to the sale of the Company’s outdoor advertising business in Canada (the “Canadian Business”). Pursuant to the Share Purchase Agreement, the Selling Subsidiaries agreed to sell all of its (and its affiliates) equity interests in Outdoor Systems Americas ULC and its subsidiaries (the “Transaction”), which hold all of the assets of the Canadian Business, to the Buyer, for C$410.0 million in cash, payable on the date of the consummation of the Transaction (the “Closing”). The purchase price is subject to (i) adjustments at and following the Closing for (1) working capital, cash, indebtedness, capital expenditures and transaction expenses, and (2) the potential sale of the Canadian joint venture in which a subsidiary of Outdoor Systems Americas ULC holds an equity interest (the “JV”) to the JV partner holding the remaining equity interest in the JV, instead of the Buyer; and (ii) a holdback to be released at or following the Closing, in whole or in part, if certain third party contracts are renewed or extended on certain terms. The consummation of the Transaction is expected to occur in 2024, subject to certain closing conditions, including, among others, (i) the absence of any enacted or pending law, order, judgment or litigation by a governmental authority prohibiting the consummation of the Transaction, and (ii) receipt of antitrust approval in Canada (the “Antitrust Approval”). The obligation of the Buyer to consummate the Transaction is also conditioned on the absence of a material adverse effect on the Canadian Business following the date of the Share Purchase Agreement and the Selling Subsidiaries’ obligation to spend a target percentage of forecasted capital expenditures through the Closing. The obligation of each party to consummate the Transaction is conditioned on each party’s representations and warranties being true and correct and each party having performed in all material respects its obligations under the Share Purchase Agreement. In addition, the Share Purchase Agreement may be terminated under certain circumstances, including (i) by mutual written agreement of the Buyer and the Selling Subsidiaries; (ii) by either the Buyer or the Selling Subsidiaries if the Closing does not occur by July 22, 2024, with extensions by the Buyer or the Selling Subsidiaries under certain conditions until no later than October 22, 2024 (the “Outside Date”); or (iii) by either the Buyer or the Selling Subsidiaries if a failure by either the Buyer or the Seller Subsidiaries is the principal cause of any closing condition not being satisfied. If the Antitrust Approval is not received by the Outside Date and the principal cause of such failure is not a failure of the Selling Subsidiaries or its subsidiaries to perform any of their obligations under the Share Purchase Agreement, the Buyer will pay a termination fee to the Selling Subsidiaries in the amount of C$20.0 million.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of estimates	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, including the impact of events such as the COVID-19 pandemic and the current heightened levels of inflation, 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.

New Accounting Standards	Adoption of New Accounting StandardsIn the first quarter of 2023, we adopted the Financial Accounting Standards Board’s (the “FASB”) guidance on the recognition and measurement of contract assets and contract liabilities acquired in a business combination. At the acquisition date, the acquirer should account for the related revenue contracts as if it had originated the contracts. The guidance also provides certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. We will implement this guidance when accounting for business combinations in the future.
