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.”). 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 all of the 25 largest markets in the U.S. and approximately 120 markets across 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 hold all of the assets of the Company’s outdoor advertising business in Canada (the “Canadian Business”). (See Note 13. Acquisitions and Dispositions : Dispositions : Canadian Business .) Basis of Presentation and Use of Estimates The accompanying 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 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 years presented. 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 11. 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. Revision of Previously Issued Financial Information In the third quarter of 2024, we identified an error related to the accounting for noncontrolling interests in our consolidated joint ventures, which include buy/sell clauses. The error related to the appropriate classification of these noncontrolling interests as redeemable and recognition of these redeemable noncontrolling interests at the maximum redemption value for each period. The Company assessed the materiality of the error on its previously issued financial statements in accordance with the SEC’s Staff Accounting Bulletin (“SAB”) No. 99 and SAB No. 108 and concluded that the amount was not material, individually or in the aggregate, to any of its previously issued financial statements, but would have been material to certain of our financial statements in the current period. Accordingly, we have revised our previously issued financial information. All relevant prior period amounts affected by these revisions have been corrected in the applicable Notes to the Consolidated Financial Statements, as appropriate. Any prior periods not presented herein may be revised in future filings to the extent necessary. (See Note 20. Revised Consolidated Financial Information .) As previously disclosed, for the three months ended March 31, 2023, the Company recorded an out-of-period adjustment relating to variable billboard property lease costs and accrued lease and franchise costs in 2022, resulting in a $5.2 million increase in operating expenses for the three months ended March 31, 2023. The Company assessed the materiality of the amount reflected in this adjustment on its previously issued financial statements in accordance with the SEC’s SAB No. 99 and SAB No. 108 and concluded that the amount was not material, individually or in the aggregate, to any of its previously issued financial statements. In the third quarter of 2024, we voluntarily revised our previously issued financial information to reflect the out-of-period adjustment amount. Prior periods not presented herein will be voluntarily revised, as applicable, in future filings. (See Note 20. Revised Consolidated Financial Information .) The impact of the revisions have been reflected throughout the Consolidated Financial Statements, including the applicable Notes to the Consolidated Financial Statements, as appropriate.

Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation— The Consolidated Financial Statements include the accounts of OUTFRONT Media Inc. and all of its subsidiaries in which a controlling interest is maintained. Controlling interest is determined by majority ownership interest and the absence of substantive third-party participating rights. Investments over which we have a significant influence or ownership of more than 20% but less than or equal to 50%, without a controlling interest, are accounted for under the equity method. Investments of 20% or less, over which we have no significant influence, that do not have a readily determinable fair value, are measured at cost less impairment, if any. Intercompany transactions have been eliminated. Cash and Cash Equivalents —Cash and cash equivalents consist of cash on hand and short-term (maturities of three months or less at the date of purchase) highly liquid investments. Receivables —Receivables consist primarily of trade receivables from customers, net of advertising agency commissions, and are stated net of an allowance for doubtful accounts. The provision for doubtful accounts is estimated based on historical bad debt experience, the aging of accounts receivable, industry trends and economic indicators, recent payment history for specific customers and expected future trends. New York Metropolitan Transportation Authority (the “MTA”) Agreement— Under our agreement with the MTA, as title of the various digital displays we are obligated to deploy transfers to the MTA on installation, the cost of deploying these screens throughout the transit system does not represent our property and equipment. The portion of deployment costs expected to be reimbursed from transit franchise fees that would otherwise be payable to the MTA are recorded as Prepaid MTA equipment deployment costs on the Consolidated Statement of Financial Position and charged to operating expenses as advertising revenue is generated. The short-term portion of Prepaid MTA equipment deployment costs represents the costs that we expect to recover from the MTA in the next twelve months. The portion of deployment costs expected to be reimbursed from advertising revenues that would otherwise be retained by us under the contract are recorded as Intangible assets on the Consolidated Statement of Financial Position and charged to amortization expense on a straight-line basis over the contract period. We assess the recoverability of the MTA contract on an as-needed basis and apply significant judgment in assessing factors to determine if there is an indication that the revenues expected to be generated over the term of the agreement will be sufficient to cover all or a portion of the equipment deployment costs, including evaluating macroeconomic conditions, industry trends, and events specific to the Company, including monitoring the Company’s actual installation of digital displays against the deployment schedule. Additionally, we assess these factors by comparing revenue projections of the deployed digital displays to actual financial results. Property and Equipment —Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives as follows: Buildings and improvements 15 to 35 years Advertising structures 3 to 20 years Furniture, equipment and other 3 to 10 years For advertising structures associated with a contract, the assets are depreciated over the shorter of the contract term or useful life. Maintenance and repair costs to maintain property and equipment in their original operating condition are charged to expense as incurred. Improvements or additions that extend the useful life of the assets are capitalized. When an asset is retired or otherwise disposed of, the associated cost and accumulated depreciation are removed and the resulting gain or loss is recognized. Construction in progress includes all costs capitalized related to projects, primarily related to in-process digital conversion and development, which have yet to be placed in service. Business Combinations and Asset Acquisitions —We routinely acquire out-of-home advertising assets, including advertising structures, permits and leasehold agreements. We determine the accounting for these transactions by first evaluating whether the assets acquired and liabilities assumed, if any, constitute a business using the guidelines in the Financial Accounting Standards Board (“FASB”) guidance for business combinations. If the assets acquired and liabilities assumed constitute a business, the purchase price is allocated to the tangible and identifiable intangible net assets acquired based on their estimated fair values with the excess of the purchase price over those estimated fair values recorded as goodwill. If the acquired assets do not constitute a business, we allocate the purchase price to the individual tangible and intangible assets acquired based on their relative fair values. Impairment of Long-Lived Assets— Long-lived assets held for sale are required to be measured at the lower of their carrying value (including unrecognized foreign currency translation adjustment losses) or fair value less cost to sell. Long-lived assets are assessed for impairment whenever there is an indication that the carrying amount of the asset may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted cash flows generated by those assets to the respective asset’s carrying value. The amount of impairment loss, if any, will be measured by the difference between the net carrying value and the estimated fair value of the asset. We compute the estimated fair value of each asset group for which we perform a quantitative assessment using an income approach. Under the income approach, the fair value is determined using a discounted cash flow model. Our cash flow models requires us to use significant estimates and assumptions such as projected revenue growth rates, billboard lease and transit franchise expenses, other operating and selling, general and administrative expenses, capital expenditures, and discount rates. The projected revenue growth rates, billboard lease and transit franchise expenses, other operating and selling, general and administrative expenses and capital expenditures are based on our internal forecasts of future performance, as well as historical trends. The discount rates represent the weighted average cost of capital derived using known and estimated market metrics. There can be no assurance that these estimates and assumptions will prove to be an accurate prediction of the future, and a downward revision of these estimates and/or assumptions would decrease the fair values of our asset groups, which could result in additional impairment charges in the future. Goodwill— Goodwill is allocated to various reporting units. Goodwill is not amortized but is tested qualitatively and/or quantitatively at the reporting-unit level annually for impairment as of October 31 of each year and between annual tests if events occur or circumstances change that would more likely than not reduce the fair value below its carrying amount. A qualitative test assesses macroeconomic conditions, industry and market conditions, cost factors, overall financial performance and other relevant entity specific events, as well as events affecting a reporting unit. If after the qualitative assessment, we determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we perform a quantitative assessment. We may also choose to only perform a quantitative assessment. We compute the estimated fair value of each reporting unit for which we perform a quantitative assessment using an income approach. Under the income approach, the fair value is determined using a discounted cash flow model. Our discounted cash flow value is calculated by adding the present value of the estimated annual cash flows over a discrete projection period to the terminal value, which represents the value of the projected cash flows beyond the discrete projection period. Our discounted cash flow model requires us to use significant estimates and assumptions such as projected revenue growth rates, terminal growth rates, billboard lease and transit franchise expenses, other operating and selling, general and administrative expenses, capital expenditures, contract renewals and extensions, and discount rates. The projected revenue growth rates, billboard lease and transit franchise expenses, other operating and selling, general and administrative expenses, capital expenditures and contract renewals and extensions for the projection period are based on our internal forecasts of future performance, as well as historical trends. The terminal value is estimated based on a perpetual nominal growth rate, which is based on projected long-range inflation and long-term industry projections. The discount rates represent the weighted average cost of capital derived using known and estimated market metrics. There can be no assurance that these estimates and assumptions will prove to be an accurate prediction of the future, and a downward revision of these estimates and/or assumptions would decrease the fair values of our reporting units, which could result in additional impairment charges in the future. If the carrying value of a reporting unit is greater than its fair value, a goodwill impairment charge will be recorded as a non-cash charge for the difference up to the carrying value of the goodwill. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Intangible Assets —Intangible assets, which primarily consist of acquired permits and leasehold agreements and franchise agreements, are amortized by the straight-line method over their estimated useful lives, which range from five Leases (Lessees) —We generally lease the underlying sites upon which the physical billboard structures on which we display advertising copy for our customers are located. We also have leases for office and warehouse spaces. All leases are recorded on the Consolidated Statement of Financial Position and we recognize lease expense on a straight-line basis over the lease term. We do not separate lease and non-lease components from contracts. Many of our leases include one or more options to renew, with renewal terms that can extend the lease term for varying lengths of time. These renewal provisions typically require consent of both parties. Many of our leases also contain termination provisions at our option, based on a variety of factors, including termination due to changing economic conditions of the related billboard location. Certain of our lease agreements include rental payments based on a percentage of revenue over contractual levels and others include rental payments adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. When available, we use the rate implicit in the lease to discount lease payments to present value; however, most of our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate to discount the lease payments based on information available at lease commencement or amendment. We rent or sublease certain real estate to third parties. Leases (Lessors) —Our agreements with customers to advertise on our billboards are considered operating leases. Substantially all of our advertising structures (see Note 3. Property and Equipment, Net ) are utilized to lease advertising space to customers, for which the contracts are accounted for as rental income. Billboard display revenues are recognized as rental income on a straight-line basis over the customer lease term. We exclude from rental income all taxes assessed by a governmental authority that we collect from customers. These operating leases are short-term in duration, typically a term of 4 weeks to one year and do not include any variable lease provisions or options to extend the lease. Certain contracts may include provisions for the early termination of the lease after an agreed upon notice period. We account for non-lease installation services and the lease associated with providing advertising space on our billboards as a combined component under the lease standard. Hedging Activities —We have utilized interest rate cash flow swap agreements in the past to effectively convert a portion of our variable rate debt to a fixed rate and may do so again in the future. The interest rate swaps were designated and qualified as cash flow hedges and, as a result, changes in the fair value of the swaps were recorded in Other comprehensive income (loss) before taxes on the Consolidated Statements of Comprehensive Income. Redeemable Noncontrolling Interests —Independent noncontrolling stockholders in certain consolidated subsidiaries of the Company have buy/sell arrangements under their respective joint venture operating agreements that allow them to sell their equity interests to the Company upon the satisfaction of certain conditions, principally the passage of time. To the extent that the redemption amount of these interests exceeds the value determined by normal noncontrolling interest accounting, the value of such interests is adjusted to the redemption amount with a corresponding adjustment to Additional Paid-In Capital on our Consolidated Statements of Financial Position. To the extent that the noncontrolling interests’ buy/sell arrangement redemption amount is correlated with the estimated fair value of the subsidiary or its underlying assets, we have used the market method to estimate such fair values. Revenue Recognition —We derive Revenues from the following sources: (i) billboard displays, (ii) transit displays, and (iii) other. Billboard display revenues are derived from providing advertising space to customers on our physical billboards or other outdoor structures. We generally (i) own the physical structures on which we display advertising copy for our customers, (ii) hold the legal permits to display advertising thereon, and (iii) lease the underlying sites. Billboard display revenues and installation services generated from traditional contracts are recognized on a combined basis under the lease accounting standard as rental income on a straight-line basis over the customer lease term. Transit display revenues are derived from 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. Transit display contracts typically require the installation and delivery of multiple advertising displays, for which locations are not specifically identified. Installation services are highly interdependent with the provision of advertising space, and therefore the installation and display of advertising is recognized as a single performance obligation. Transit display revenues generated from traditional contracts are recognized based on the level of units displayed in proportion to the total units to be displayed over the contract period. Billboard display and Transit display revenues generated from programmatic advertising platforms are recognized as rental income as the related advertisement is displayed. Billboard and Transit display revenues derived from impression-based sales contracts fulfilled on direct sales advertising platforms are recognized as revenue over the contract period based pro-rata on the number of impressions delivered in proportion to the total number of impressions to be delivered. Revenues generated from programmatic advertising platforms are based on agreements with the platforms, rather than direct contracts with individual advertisers. Other revenues are derived primarily from providing print production services for advertisements to be displayed on our billboards or other outdoor sites, or on displays that we operate within transit systems. Print production services are not interrelated with the provision of advertising space and are considered a distinct performance obligation. Production revenue is recognized over the production period, which is typically very short in duration. Our traditional billboard display and transit display contracts with customers range from four weeks to one year and billing commences at the beginning of the contract term, with payment generally due within 30 days of billing. For the majority of our contracts, transaction prices are explicitly stated. Any contracts with transaction prices that contain multiple performance obligations are allocated primarily based on a relative standalone selling price basis. Deferred revenues primarily consist of revenues collected in advance of being earned. For all revenue sources, we evaluate whether we should be considered the principal (i.e., report revenues on a gross basis) or an agent (i.e., report revenues on a net basis). We are considered the principal in our arrangements and report revenues on a gross basis, wherein the amounts billed to customers are recorded as revenues, and amounts paid to municipalities, transit operators and suppliers are recorded as expenses. We are considered the principal because we control the advertising space before and after the contract term, are primarily responsible to our customers, have discretion in pricing and typically have inventory risk. For space provided to advertisers through the use of an advertising agency whose commission is calculated based on a stated percentage of gross advertising spending, our Revenues are reported net of agency commissions. Concentration of Credit Risk— In the opinion of management, credit risk is limited due to the large number of customers and advertising agencies utilized. We perform credit evaluations on our customers and agencies and believe that the allowances for doubtful accounts are adequate. Billboard Property Lease and Transit Franchise Expenses —Our billboards are primarily located on leased real property. Lease agreements are negotiated for varying terms ranging from one month to multiple years, most of which provide renewal options. Lease costs consist of a fixed monthly amount and certain lease agreements also include contingent rent based on the revenues we generate from the leased site. Property leases are generally paid in advance for periods ranging from one The fixed component of lease costs is expensed evenly over the non-cancellable contract term, and contingent rent is expensed as incurred when the related revenues are recognized. Our transit franchise agreements have fixed terms, are typically terminable for convenience at the option of the governmental entity (other than with respect to the MTA), and generally provide for payments to the governmental entity based on a percentage of revenues generated under the contract and/or a guaranteed minimum annual payment. The costs which are determined based on a percentage of revenues are expensed as incurred when the related revenues are recognized, and the guaranteed minimum annual payment is expensed over the contract term. Direct Lease Acquisition Costs— Variable commissions directly associated with billboard revenues are amortized on a straight-line basis over the related customer lease term, which generally ranges from four weeks to one year. Amortization of direct lease acquisition costs are presented within Selling General and Administrative expenses (“ SG&A ”) in the accompanying Consolidated Statements of Operations. Foreign Currency Translation and Transactions— The assets and liabilities of foreign subsidiaries are translated at exchange rates in effect at the balance sheet date, while results of operations are translated at average exchange rates for the respective periods. Any gain or loss on translation is included within other comprehensive income (loss) and Accumulated other comprehensive loss on our Consolidated Statement of Financial Position. Foreign currency transaction gains and losses are included in Other income (loss), net, on the Consolidated Statements of Operations. Income Taxes —As a REIT, we generally will not be subject to federal, state and local 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, and certain of our foreign subsidiaries, as taxable REIT subsidiaries (“TRSs”). As such, the taxable income of our TRSs will be subject to federal, state and local income taxation at regular corporate rates. Income taxes are accounted for under the asset and liability method of accounting. Deferred income tax assets and liabilities are recognized for the estimated future tax effects of temporary differences between the financial statement carrying amounts and their respective tax basis. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax assets will not be realized. We have applied the FASB’s guidance relating to uncertainty in income taxes recognized. Under this guidance we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The tax benefits recognized from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The guidance on accounting for uncertainty in income taxes also provides guidance on de-recognition, classification, interest and penalties on income taxes, and accounting in interim periods. Asset Retirement Obligation —An asset retirement obligation is established for the estimated future obligation, upon termination or non-renewal of a lease, associated with removing structures from the leased property and, when required by the contract, the cost to return the leased property to its original condition. These obligations are recorded at their present value in the period in which the liability is incurred and are initially recorded as part of the related assets’ carrying value. Accretion of the liability is recognized in selling, general and administrative expenses and the capitalized cost is depreciated over the expected useful life of the related asset. Stock-based Compensation —We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized over the vesting period during which an employee is required to provide service in exchange for the award. Adoption of New Accounting Standards In the fourth quarter of 2024, we adopted the FASB’s guidance to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. (See Note 19. Segment Information .) Recent Pronouncements In November 2024 and January 2025, the FASB issued guidance to improve disclosure of expenses by providing more detailed information about specific expense categories included in commonly presented financial statement expense captions in the notes to the financial statements. The guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. This guidance does not change or remove current expense disclosure requirements and will not have any impact on our consolidated financial statements. In December 2023, the FASB issued guidance to enhance the transparency and decision usefulness of income tax disclosures primarily related to rate reconciliation and income taxes paid information. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Retrospective application is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements.

Long-Lived Assets	Long-Lived Assets Goodwill For the years ended December 31, 2024 and 2023, the changes in the book value of goodwill by segment were as follows: (in millions) Billboard Transit Other Total As of December 31, 2022 $ 2,006.4 $ 47.6 $ 22.4 $ 2,076.4 Dispositions (a) — — (22.9) (22.9) Currency translation adjustments — — 0.5 0.5 Impairment — (47.6) — (47.6) As of December 31, 2023 2,006.4 — — 2,006.4 As of December 31, 2024 $ 2,006.4 $ — $ — $ 2,006.4 (a) In 2023, in connection with the Transaction, Goodwill in Other was reclassified as Assets held for sale on the Consolidated Statement of Financial Position. (See Note 13. Acquisitions and Dispositions : Dispositions : Canadian Business .) As a result of an impairment analysis performed during the second quarter of 2023, we determined that the carrying value of our historical Transit reporting unit exceeded its fair value and we recorded an impairment charge of $47.6 million in the Consolidated Statements of Operations. In the fourth quarter of 2024, we performed a qualitative assessment of our Billboard reporting unit for possible goodwill impairment and no additional goodwill impairment was identified. 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 Impairment Net As of December 31, 2024: Permits and leasehold agreements $ 1,535.9 $ (935.7) $ — $ 600.2 Franchise agreements (a) 888.8 (360.9) (485.8) 42.1 Other intangible assets 19.5 (9.8) — 9.7 Total intangible assets $ 2,444.2 $ (1,306.4) $ (485.8) $ 652.0 As of December 31, 2023: Permits and leasehold agreements $ 1,535.5 $ (893.8) $ — $ 641.7 Franchise agreements (a) 934.8 (426.4) (467.9) 40.5 Other intangible assets 19.5 (6.3) — 13.2 Total intangible assets $ 2,489.8 $ (1,326.5) $ (467.9) $ 695.4 (a) We reclassified all Prepaid MTA equipment deployment costs (see Note 18. Commitments and Contingencies ) and recorded impairments in the second, third and fourth quarters of 2023, as well as the first and second quarters of 2024, due to the long-term outlook of our Transit reporting unit. In 2024, we acquired 21 displays, resulting in amortizable intangible assets for permits and leasehold agreements, and other intangible assets of $16.7 million, which are amortized using the straight-line method over their estimated useful lives, an average period of 18.1 years. All of our intangible assets, except goodwill, are subject to amortization. Amortization expense was $72.0 million in 2024, $81.2 million in 2023 and $73.3 million in 2022. As a result of negative aggregate undiscounted cash flow forecasts related to our MTA asset group, we performed quarterly impairment analyses on the MTA asset group during the three months ended March 31, 2024 and June 30, 2024, and recorded impairment charges of $9.1 million and $8.8 million, respectively, in those periods for a total of $17.9 million in the six months ended June 30, 2024. The impairment charges recorded during 2024 represented additional MTA equipment deployment cost spending during the six months ended June 30, 2024. Our analysis performed as of September 30, 2024, and December 31, 2024, resulted in positive aggregate cash flows in excess of the carrying value of our MTA asset group. As such, no impairment charges were recorded during each of the three months ended September 30, 2024, and December 31, 2024. In 2023, we recorded impairment charges of $486.8 million, primarily representing $466.2 million of impairment charges related to our MTA asset group. We expect our aggregate annual amortization expense for intangible assets for each of the years 2025 through 2029, to be as follows: (in millions) 2025 2026 2027 2028 2029 Amortization expense $ 67.5 $ 62.9 $ 58.1 $ 53.9 $ 50.7

As of December 31, 2024, a discount of $0.5 million on the Term Loan remains unamortized. The discount is being amortized through Interest expense, net, on the Consolidated Statement of Operations. In June 2024, we prepaid $200.0 million of the outstanding principal balance on the Term Loan. In 2024, we recorded a Loss on extinguishment of debt of $1.2 million on the Consolidated Statement of Operations, relating to the write-off of deferred financing costs and a portion of the discount on the Term Loan. 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”). As of December 31, 2024, 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 $2.0 million in 2024, $1.7 million in 2023 and $1.6 million in 2022. As of December 31, 2024, we had issued letters of credit totaling approximately $5.5 million against the letter of credit facility sublimit under the Revolving Credit Facility. Standalone Letter of Credit Facilities As of December 31, 2024, we had issued letters of credit totaling approximately $65.0 million under our aggregate $81.0 million standalone letter of credit facilities. The total fees under the letter of credit facilities in 2024, 2023 and 2022 were immaterial. Accounts Receivable Securitization Facilities As of December 31, 2024, we have a $150.0 million revolving accounts receivable securitization facility (the “AR Facility”), which terminates in June 2027, unless further extended. On June 14, 2024, we entered into an amendment to the agreements governing the AR Facility, pursuant to which we (i) extended the term of the AR Facility so that it now terminates on June 14, 2027, unless further extended; and (ii) modified the upfront fee and modified the program fee so that the program fee may increase or decrease based on the Company’s Consolidated Net Secured Leverage Ratio (as defined and described below). The amendment to the agreements governing the AR Facility do not change how we account for the AR Facility as a collateralized financing activity. 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 December 31, 2024, there were $10.0 million of outstanding borrowings under the AR Facility, at a borrowing rate of 5.9%. As of December 31, 2024, borrowing capacity remaining under the AR Facility was $140.0 million based on approximately $345.3 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 $0.3 million in 2024, $0.2 million in 2023 and $0.3 million in 2022. In January 2025, we made a repayment of $10.0 million under the AR Facility. 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 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 December 31, 2024, our Consolidated Total Leverage Ratio was 4.8 to 1.0, as adjusted to give pro forma effect to the Transaction, 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 December 31, 2024, our Consolidated Net Secured Leverage Ratio was 1.5 to 1.0, as adjusted to give pro forma effect to the Transaction, in accordance with the Credit Agreement. As of December 31, 2024, we are in compliance with our debt covenants. Deferred Financing Costs As of December 31, 2024, we had deferred $21.0 million in fees and expenses associated with the Term Loan, the Revolving Credit Facility, the AR Facility and our senior 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 notes.

Redeemable noncontrolling interest	Redeemable Noncontrolling Interests To the extent that the noncontrolling interests’ buy/sell arrangement redemption amount is correlated with the estimated fair value of the subsidiary or its underlying assets, we have used the market method to estimate such fair values. The redemption value of these interests, as of all periods presented, is classified as Level 3. (See Note 8. Debt : Fair Value .) In the third quarter of 2024, as a result of the exercise of a buy/sell arrangement by one of our joint venture partners, we purchased the outstanding noncontrolling interest in a consolidated subsidiary for cash and non-cash consideration totaling $24.6 million.

Equity [Abstract]
Equity	Equity As of December 31, 2024, 450,000,000 shares of our common stock, par value $0.01 per share, were authorized; 165,985,889 shares were issued and outstanding; and 50,000,000 shares of our preferred stock, par value $0.01 per share, were authorized with 125,000 shares of our Series A Convertible Perpetual Preferred Stock (the “Series A Preferred Stock”), par value $0.01 per share, issued and outstanding. 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 2024, we paid cash dividends of $8.8 million on the Series A Preferred Stock. As of December 31, 2024, 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. In 2024, no shares of our common stock were sold under the ATM Program. As of December 31, 2024, we had approximately $232.5 million of capacity remaining under the ATM Program. We issued 4,074,770 shares of common stock on December 31, 2024, to our common stockholders to pay the common stock portion of the Company’s special dividend of $0.75 per share on our common stock payable on December 31, 2024 (the “Special Dividend”). To offset the dilutive impact of the Special Dividend, on January 8, 2025, we announced a 1-for-1.024549 reverse stock split on our common stock, such that every common stockholder would receive one share of common stock for every 1.024549 shares of common stock held by such common stockholder outstanding as of January 17, 2025 (the “Reverse Stock Split”). The Reverse Stock Split took effect on January 17, 2025. As a result of the Reverse Stock Split, the number of outstanding shares of common stock as of January 17, 2025, was reduced from 170,061,181 to 165,986,229, which is substantially similar to the outstanding shares of common stock prior to the Special Dividend. The Company’s authorized shares of common stock and par value of each share of common stock remained unchanged. All shares of the Company’s common stock included in these Consolidated Financial Statements have been retroactively adjusted as though the Reverse Stock Split has been effected prior to all periods presented. On February 25, 2025, we announced that our board of directors approved a quarterly cash dividend of $0.30 per share on our common stock, payable on March 31, 2025, to stockholders of record at the close of business on March 7, 2025.

Contract Costs and Balances Variable sales commission costs directly associated with billboard display revenues are considered direct lease acquisition costs in accordance with the lease accounting standard and are capitalized and amortized on a straight-line basis over the related customer lease term (see Note 5. Leases : Lessee to the Consolidated Financial Statements). Amortization of direct lease acquisition costs is presented within SG&A in the accompanying Consolidated Statements of Operations. Variable sales commission costs which are directly associated with transit display and other revenues are included in SG&A on the Consolidated Statement of Operations, and are expensed as incurred since the amortization period of the asset would have been less than one year. Amounts to be collected from customers for revenues recognized in previous periods are included in Receivables, less allowance , on the Consolidated Statement of Financial Position. Amounts collected from customers for revenues to be recognized in future periods are included in Deferred revenues on the Consolidated Statement of Financial Position.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Under the OUTFRONT Media Inc. Amended and Restated Omnibus Stock Incentive Plan (the “Stock Plan”), we have 19,575,000 shares of our common stock reserved for issuance. Under the Stock Plan, the board of directors is authorized to grant awards of options to purchase shares of our common stock, stock appreciation rights, restricted and unrestricted stock, restricted share units (“RSUs”), dividend equivalents, performance awards, including performance-based restricted share units (“PRSUs”), and other equity-related awards and cash payments to all of our employees and non-employee directors and employees of our subsidiaries. In addition, consultants and advisors who perform services for us and our subsidiaries may, under certain conditions, receive grants under the Stock Plan. RSUs and PRSUs accrue dividend equivalents in amounts equal to the regular cash dividends paid on our common stock and will be paid in either cash or stock. Accrued dividend equivalents payable in stock shall convert to shares of our common stock on the date of vesting. Compensation expense for RSUs is determined based upon the market price of the shares underlying the awards on the date of grant and expensed over the vesting period, which is generally a three-year service period. For PRSU awards, the number of shares an employee earns may range from 0% to 120% based on the outcome of a one-year performance condition. Compensation expense is recorded based on the probable outcome of the performance condition. On an annual basis, our board of directors will review actual performance and certify the degree to which performance goals applicable to the award have been met. Forfeitures of RSUs are recorded as incurred. Adjustments are made to compensation expense based on actual forfeitures. The following table summarizes our stock-based compensation expense for 2024, 2023 and 2022. Year Ended December 31, (in millions) 2024 2023 2022 Stock-based compensation expense (RSUs and PRSUs), before income taxes $ 30.8 $ 28.4 $ 33.8 Tax benefit (1.1) (1.0) (1.6) Stock-based compensation expense, net of tax $ 29.7 $ 27.4 $ 32.2 As of December 31, 2024, total unrecognized compensation cost related to non-vested RSUs and PRSUs was $24.8 million, which is expected to be recognized over a weighted average period of 1.7 years. RSUs and PRSUs The following table summarizes the 2024 activity of the RSUs and PRSUs issued to our employees.

Retirement Benefits [Abstract]
Retirement Benefits	Retirement Benefits During 2024, we sponsored two defined benefit pension plans covering specific groups of employees in Canada and the U.S. On June 7, 2024, we completed the sale of the Canadian Business in the Transaction, which included the Outfront Media Canada LP pension plan (the “Plan”). Prior to the Transaction, the benefits for the pension plan in Canada were based primarily on an employee’s years of service and an average of the employee’s highest five years of earnings. Participating employees in the pension plan in Canada were vested after two years of service or immediately, depending on the province of their employment. Prior to the Transaction, we funded the pension plan in Canada in accordance with the rules and regulations of the Pension Benefits Act of the Province of Ontario, Canada. Canada pension plan assets consist principally of insurance contracts, equity securities and corporate and government-related fixed income securities, and global infrastructure. The pension plan in the U.S. covers a small number of hourly employees. The investments of the pension plan in the U.S. consist entirely of the plan’s interest in a trust, which invests the assets of this plan. The pension plan in the U.S. is funded in accordance with requirements of the Employee Retirement Income Security Act of 1974, as amended. The benefit obligation, fair value of plan assets, net periodic pension costs and activity within these balances as of and for the year ended December 31, 2024, related to the pension plan in the U.S. and activity for the Canada pension plan prior to the Transaction, are immaterial. The tables below represent the balances and activity related to both the Canadian and U.S. pension plans for prior periods. We use a December 31 measurement date for all pension plans. The following table sets forth the change in benefit obligation for our pension plans. As of December 31, (in millions) 2023 2022 Benefit obligation, beginning of year $ 47.0 $ 65.3 Interest cost 2.1 1.9 Actuarial gain (0.3) (14.8) Settlements paid (20.2) — Benefits paid (2.0) (2.2) Cumulative translation adjustments 0.6 (3.2) Benefit obligation, end of year $ 27.2 $ 47.0 The following table sets forth the change in plan assets for our pension plans. As of (in millions) 2023 Fair value of plan assets, beginning of year $ 55.5 Actual return on plan assets 2.9 Settlements paid (20.2) Benefits paid (2.0) Cumulative translation adjustments 0.9 Fair value of plan assets, end of year $ 37.1 The unfunded status of pension benefit obligations and the related amounts recognized on the Consolidated Statement of Financial Position were as follows: As of (in millions) 2023 Funded status, end of year $ 9.9 Amounts recognized on the Consolidated Statement of Financial Position: Assets held for sale 10.4 Other liabilities (0.5) Net amounts recognized 9.9 The following amounts were recognized in accumulated other comprehensive loss on the Consolidated Statement of Financial Position. As of (in millions) 2023 Net actuarial gain $ 0.4 Deferred income taxes (0.1) Net amount recognized in accumulated other comprehensive income $ 0.3 The accumulated benefit obligation for the defined benefit pension plans was $25.1 million as of December 31, 2023. The following table presents our benefit obligations and fair value of plan assets. As of (in millions) 2023 Projected benefit obligation $ 27.2 Accumulated benefit obligation 25.1 Fair value of plan assets 37.1 The following tables present the components of net periodic pension cost and amounts recognized in other comprehensive income (loss). As of December 31, (in millions) 2023 2022 Interest cost 2.1 1.9 Expected return on plan assets (2.6) (2.8) Settlement gain (0.5) — Net periodic pension cost $ (1.0) $ (0.9) As of and for the Year Ended December 31, 2023 Weighted average assumptions used to determine benefit obligations: Discount rate 4.8 % Rate of compensation increase 3.3 Weighted average assumptions used to determine net periodic cost: Discount rate 5.0 Expected long-term return on plan assets 4.2 Rate of compensation increase 3.3 For the pension plan, the discount rate is determined based on the yield on portfolios of high quality bonds, constructed to provide cash flows necessary to meet the expected future benefit payments, as determined for the projected benefit obligation. The expected return on plan assets assumption was derived using the current and expected asset allocation of the pension plan assets and considering historical as well as expected returns on various classes of plan assets. Plan Assets Our plan assets are included in a trust in the U.S. The asset allocations of these trusts are based upon an analysis of the timing and amount of projected benefit payments, projected company contributions, the expected returns and risk of the asset classes and the correlation of those returns. The following tables set forth our pension plan assets measured at fair value on a recurring basis as of December 31, 2023. These assets have been categorized according to the three-level fair value hierarchy established by the FASB which prioritizes the inputs used in measuring fair value. Level 1 is based on quoted prices for the asset in active markets. Level 2 is based on inputs that are observable other than quoted market prices in active markets, such as quoted prices for the asset in inactive markets or quoted prices for similar assets. Level 3 is based on unobservable inputs that market participants would use in pricing the asset. As of December 31, 2023 (in millions) Level 1 Level 2 Level 3 Total Cash and cash equivalents $ 0.1 $ — $ — $ 0.1 Fixed income securities: Corporate bonds (a) 0.6 — — 0.6 Equity securities : U.S. equity 0.8 — — 0.8 International equity 0.3 — — 0.3 Total assets in fair value hierarchy $ 1.8 $ — $ — $ 1.8 Common collective funds measured at net asset value 35.3 Total assets $ 37.1 (a) Securities of diverse industries, substantially all investment grade. Significant changes in Level 3 plan assets are as follows: Year Ended December 31, (in millions) 2023 Insurance contracts: Beginning of year $ 22.0 Settlement (a) (22.0) End of year $ — (a) In the fourth quarter of 2023, insurance contracts that were part of the assets of the Plan were converted into buy-out annuities with third-party insurance companies. Former employees now collect their benefit from the third-party insurance companies and the Plan no longer has liability associated with those former employees. Money market investments are carried at amortized cost which approximates fair value due to the short-term maturity of these investments. Investments in equity securities are reported at fair value based on quoted market prices on national security exchanges. The fair value of investments in common collective funds are determined using the Net Asset Value (“NAV”) provided by the administrator of the fund. The NAV is determined by each fund’s trustee based upon the fair value of the underlying assets owned by the fund, less liabilities, divided by the number of outstanding units. The fair value of government related securities and corporate bonds is determined based on quoted market prices on national security exchanges, when available, or using valuation models which incorporate certain other observable inputs including recent trading activity for comparable securities and broker-quoted prices. Estimated future benefit payments for pension plans and expected contributions to our defined benefit pension plan in the U.S. are estimated to be immaterial. Multi-Employer Pension and Postretirement Benefit Plans We contribute to multi-employer plans that provide pension and other postretirement benefits to certain employees under collective bargaining agreements. Contributions to these plans were $4.2 million in 2024, $3.3 million in 2023 and $3.5 million in 2022. Based on our contributions to each individual multi-employer plan relative to the total contributions of all participating employers in such plan, no multi-employer plan was deemed to be individually significant to us.

Income Tax Disclosure [Abstract]
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 taxable REIT subsidiaries (“TRSs”). As such, we have provided for their federal, state and foreign income taxes. Cash paid for income taxes was $11.5 million in 2024, $6.7 million in 2023 and $3.3 million in 2022.

These losses can be carried forward indefinitely for federal tax purposes but are subject to certain federal, state and local utilization limitations. As of December 31, 2024, there are no undistributed earnings of foreign subsidiaries due to the sale of the Canadian Business in the Transaction. All undistributed earnings of foreign subsidiaries prior to the Transaction were distributed to our stockholders in 2024. The reserve for uncertain tax positions of $0.4 million as of December 31, 2024, includes $0.2 million which would affect our effective income tax rate if recognized in future years. We recognize interest and penalty charges related to the reserve for uncertain tax positions as part of income tax expense. These charges were not material for any of the periods presented.

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. As of December 31, 2024, guaranteed minimum annual payments are as follows: (in millions) Guaranteed 2025 $ 215.2 2026 230.3 2027 219.1 2028 222.8 2029 222.9 2030 and thereafter 286.4 Total minimum payments $ 1,396.7 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, which amounts are subject to the MTA’s ability to fulfill its pre-installation obligations under the MTA Agreement. 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 2024. In addition, we currently do not expect to recoup any equipment deployment costs throughout the remainder of the Amended Term (as defined below) of the MTA Agreement. • 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 2024, we had no recoupment from incremental revenues. As of December 31, 2024, 26,245 digital displays had been installed, composed of 5,010 digital advertising screens on subway and train platforms and entrances, 15,224 smaller-format digital advertising screens on rolling stock and 6,011 MTA communications displays. In the fourth quarter of 2024, 900 installations occurred, for a total of 6,548 installations occurring in 2024. As a result of negative aggregate undiscounted cash flow forecasts related to our MTA asset group, we performed quarterly impairment analyses on the MTA asset group during the three months ended March 31, 2024 and June 30, 2024, and recorded impairment charges of $9.1 million and $8.8 million, respectively, in those periods for a total of $17.9 million in the six months ended June 30, 2024. The impairment charges recorded during 2024 represented additional MTA equipment deployment cost spending during the six months ended June 30, 2024. Our analysis performed as of September 30, 2024, and as of December 31, 2024, resulted in positive aggregate cash flows in excess of the carrying value of our MTA asset group. As such, no impairment charges were recorded during the three months ended September 30, 2024, and three months ended December 31, 2024.

As of December 31, 2024, the outstanding letters of credit were approximately $70.5 million and outstanding surety bonds were approximately $172.5 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.

Segment Reporting [Abstract]
Segment Information	Segment Information We have identified our Chief Executive Officer as the chief operating decision maker for purposes of determining segments. We currently manage our operations through two reportable operating segments—(1) Billboard, which provides advertising space on billboard advertising structures and sites in the U.S., and (2) Transit , which provides advertising space on transit advertising displays operating under exclusive multi-year contracts with municipalities in large cities across the U.S. 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. Also included in Other are operating results for third-party digital equipment sales. The following tables set forth our financial performance by segment. We present Operating income (loss) before Depreciation , Amortization , Net (gain) loss on dispositions, Stock-based compensation and Impairment charges (“Adjusted OIBDA”) as the primary measure of profit and loss for our operating segments. Adjusted OIBDA margin is a secondary measure utilized to measure performance of our operating segments.

Accounting Changes and Error Corrections [Abstract]
Revised Consolidated Financial Information	Revised Consolidated Financial Information In the third quarter of 2024, we identified an error related to the accounting for noncontrolling interests in our consolidated joint ventures, which include buy/sell clauses. The error related to the appropriate classification of these noncontrolling interests as redeemable and recognition of these redeemable noncontrolling interests at the maximum redemption value for each period. The Company assessed the materiality of the error on its previously issued financial statements in accordance with the SEC’s SAB No. 99 and SAB No. 108 and concluded that the amount was not material, individually or in the aggregate, to any of its previously issued financial statements, but would have been material to certain of our financial statements in the current period. Accordingly, we have revised our previously issued financial information. All relevant prior period amounts affected by these revisions have been corrected in the applicable Notes to the Consolidated Financial Statements, as appropriate. Any prior periods not presented herein may be revised in future filings to the extent necessary. As previously disclosed, for the three months ended March 31, 2023, the Company recorded an out-of-period adjustment relating to variable billboard property lease costs and accrued lease and franchise costs in 2022, resulting in a $5.2 million increase in operating expenses for the three months ended March 31, 2023. The Company assessed the materiality of the amount reflected in this adjustment on its previously issued financial statements in accordance with the SEC’s SAB No. 99 and SAB No. 108 and concluded that the amount was not material, individually or in the aggregate, to any of its previously issued financial statements. In the third quarter of 2024, we voluntarily revised our previously issued financial information to reflect the out-of-period adjustment amount. Prior periods not presented herein will be voluntarily revised, as applicable, in future filings. There is no impact to net cash provided by operating activities, investing activities or financing activities in our Consolidated Statements of Cash Flows. The following table presents the impact of correcting the error related to the classification of redeemable noncontrolling interests on the affected line items of our Consolidated Statement of Financial Position as of December 31, 2023.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Cybersecurity. The Company maintains a comprehensive information security and cybersecurity program (the “Cybersecurity Program”) guided by established best practice and tailored to the Company’s business needs. The Cybersecurity Program is an extension of the Company’s enterprise risk management program that seeks to identify and manage risks throughout the Company by having its Chief Financial Officer meet with members of each of the Company’s various departments annually to solicit feedback regarding risks affecting the Company, which is then reported to the audit committee of our board of directors. Under the Cybersecurity Program, systems and networks under Company control are monitored for anomalies using various security tools that identify potential cybersecurity threats and alert the Company’s internal cybersecurity team to suspicious activity. If a potential cybersecurity incident is identified, it is investigated by the Company’s internal cybersecurity team (including the Company’s Chief Information Security Officer (the “CISO”)) to assess whether a cybersecurity incident has occurred, its severity and the risk involved, in accordance with internal processes and procedures and the Company’s incident response plan. The CISO is responsible for management of these cybersecurity processes, and reports to the Company’s Chief Information Officer (the “CIO”), who reports to the Company’s Chief Technology Officer (the “CTO”). The CISO and CIO will receive input from, and coordinate with, the CTO and the Company’s Chief Privacy Officer (the “CPO”), as necessary. If a cybersecurity incident is discovered, it must be reported by the CIO and the CISO to the Company’s senior management, including the CTO, the Company’s Chief Financial Officer and the Company’s General Counsel for further assessment regarding scope, mitigation, remediation and disclosure obligations, as applicable. The audit committee of our board of directors oversees the Company’s information security and cybersecurity risks, compliance and protections, and receives quarterly cybersecurity updates from the CISO and CIO (with input from the CTO and the CPO, as appropriate) and results of the Company’s incident response plan testing at least annually. The Cybersecurity Program team members, including the CISO and the CIO, have extensive work experience in cybersecurity, information technology engineering and the media and advertising industries, with some members holding degrees in cybersecurity and professional certifications in cybersecurity. The Cybersecurity Program team members are subject to ongoing employee trainings in cybersecurity procedures. We perform regular third-party assessments of the Cybersecurity Program, and retain specialized third-party forensics experts for escalation of certain cybersecurity incidents. In addition, we have processes, including formal security reviews and suspicious activity monitoring, to assess cybersecurity risks associated with our use of third-party service providers. To date, we have not identified any cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Company, including our business strategy, results of operations or financial condition. For additional information about our cybersecurity risks, see “Item 1A. Risk Factors—If we experience a cybersecurity incident, we may suffer reputational harm and significant legal and financial exposure.”

Accounting Policies [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, 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 York Metropolitan Authority (the "MTA") Agreement	New York Metropolitan Transportation Authority (the “MTA”) Agreement— Under our agreement with the MTA, as title of the various digital displays we are obligated to deploy transfers to the MTA on installation, the cost of deploying these screens throughout the transit system does not represent our property and equipment. The portion of deployment costs expected to be reimbursed from transit franchise fees that would otherwise be payable to the MTA are recorded as Prepaid MTA equipment deployment costs on the Consolidated Statement of Financial Position and charged to operating expenses as advertising revenue is generated. The short-term portion of Prepaid MTA equipment deployment costs represents the costs that we expect to recover from the MTA in the next twelve months. The portion of deployment costs expected to be reimbursed from advertising revenues that would otherwise be retained by us under the contract are recorded as Intangible assets
Property and Equipment	Property and Equipment —Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives as follows: Buildings and improvements 15 to 35 years Advertising structures 3 to 20 years Furniture, equipment and other 3 to 10 years For advertising structures associated with a contract, the assets are depreciated over the shorter of the contract term or useful life. Maintenance and repair costs to maintain property and equipment in their original operating condition are charged to expense as incurred. Improvements or additions that extend the useful life of the assets are capitalized. When an asset is retired or otherwise disposed of, the associated cost and accumulated depreciation are removed and the resulting gain or loss is recognized.
Business Combinations and Asset Acquisitions	Business Combinations and Asset Acquisitions —We routinely acquire out-of-home advertising assets, including advertising structures, permits and leasehold agreements. We determine the accounting for these transactions by first evaluating whether the assets acquired and liabilities assumed, if any, constitute a business using the guidelines in the Financial Accounting Standards Board (“FASB”) guidance for business combinations. If the assets acquired and liabilities assumed constitute a business, the purchase price is allocated to the tangible and identifiable intangible net assets acquired based on their estimated fair values with the excess of the purchase price over those estimated fair values recorded as goodwill. If the acquired assets do not constitute a business, we allocate the purchase price to the individual tangible and intangible assets acquired based on their relative fair values.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets— Long-lived assets held for sale are required to be measured at the lower of their carrying value (including unrecognized foreign currency translation adjustment losses) or fair value less cost to sell. Long-lived assets are assessed for impairment whenever there is an indication that the carrying amount of the asset may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted cash flows generated by those assets to the respective asset’s carrying value. The amount of impairment loss, if any, will be measured by the difference between the net carrying value and the estimated fair value of the asset. We compute the estimated fair value of each asset group for which we perform a quantitative assessment using an income approach. Under the income approach, the fair value is determined using a discounted cash flow model. Our cash flow models requires us to use significant estimates and assumptions such as projected revenue growth rates, billboard lease and transit franchise expenses, other operating and selling, general and administrative expenses, capital expenditures, and discount rates. The projected revenue growth rates, billboard lease and transit franchise expenses, other operating and selling, general and administrative expenses and capital expenditures are based on our internal forecasts of future performance, as well as historical trends. The discount rates represent the weighted average cost of capital derived using known and estimated market metrics. There can be no assurance that these estimates and assumptions will prove to be an accurate prediction of the future, and a downward revision of these estimates and/or assumptions would decrease the fair values of our asset groups, which could result in additional impairment charges in the future.
Goodwill	Goodwill—
Intangible assets	Intangible Assets —Intangible assets, which primarily consist of acquired permits and leasehold agreements and franchise agreements, are amortized by the straight-line method over their estimated useful lives, which range from five
Leases - Lessee	Leases (Lessees) —We generally lease the underlying sites upon which the physical billboard structures on which we display advertising copy for our customers are located. We also have leases for office and warehouse spaces. All leases are recorded on the Consolidated Statement of Financial Position and we recognize lease expense on a straight-line basis over the lease term. We do not separate lease and non-lease components from contracts. Many of our leases include one or more options to renew, with renewal terms that can extend the lease term for varying lengths of time. These renewal provisions typically require consent of both parties. Many of our leases also contain termination provisions at our option, based on a variety of factors, including termination due to changing economic conditions of the related billboard location. Certain of our lease agreements include rental payments based on a percentage of revenue over contractual levels and others include rental payments adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. When available, we use the rate implicit in the lease to discount lease payments to present value; however, most of our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate to discount the lease payments based on information available at lease commencement or amendment. We rent or sublease certain real estate to third parties.
Leases - Lessor	Leases (Lessors) —Our agreements with customers to advertise on our billboards are considered operating leases. Substantially all of our advertising structures (see Note 3. Property and Equipment, Net ) are utilized to lease advertising space to customers, for which the contracts are accounted for as rental income. Billboard display revenues are recognized as rental income on a straight-line basis over the customer lease term. We exclude from rental income all taxes assessed by a governmental authority that we collect from customers. These operating leases are short-term in duration, typically a term of 4 weeks to one year and do not include any variable lease provisions or options to extend the lease. Certain contracts may include provisions for the early termination of the lease after an agreed upon notice period. We account for non-lease installation services and the lease associated with providing advertising space on our billboards as a combined component under the lease standard.
Hedging Activities	Hedging Activities
Redeemable noncontrolling interests	Redeemable Noncontrolling Interests —Independent noncontrolling stockholders in certain consolidated subsidiaries of the Company have buy/sell arrangements under their respective joint venture operating agreements that allow them to sell their equity interests to the Company upon the satisfaction of certain conditions, principally the passage of time. To the extent that the redemption amount of these interests exceeds the value determined by normal noncontrolling interest accounting, the value of such interests is adjusted to the redemption amount with a corresponding adjustment to Additional Paid-In Capital
Revenue Recognition	Revenue Recognition —We derive Revenues from the following sources: (i) billboard displays, (ii) transit displays, and (iii) other. Billboard display revenues are derived from providing advertising space to customers on our physical billboards or other outdoor structures. We generally (i) own the physical structures on which we display advertising copy for our customers, (ii) hold the legal permits to display advertising thereon, and (iii) lease the underlying sites. Billboard display revenues and installation services generated from traditional contracts are recognized on a combined basis under the lease accounting standard as rental income on a straight-line basis over the customer lease term. Transit display revenues are derived from 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. Transit display contracts typically require the installation and delivery of multiple advertising displays, for which locations are not specifically identified. Installation services are highly interdependent with the provision of advertising space, and therefore the installation and display of advertising is recognized as a single performance obligation. Transit display revenues generated from traditional contracts are recognized based on the level of units displayed in proportion to the total units to be displayed over the contract period. Billboard display and Transit display revenues generated from programmatic advertising platforms are recognized as rental income as the related advertisement is displayed. Billboard and Transit display revenues derived from impression-based sales contracts fulfilled on direct sales advertising platforms are recognized as revenue over the contract period based pro-rata on the number of impressions delivered in proportion to the total number of impressions to be delivered. Revenues generated from programmatic advertising platforms are based on agreements with the platforms, rather than direct contracts with individual advertisers. Other revenues are derived primarily from providing print production services for advertisements to be displayed on our billboards or other outdoor sites, or on displays that we operate within transit systems. Print production services are not interrelated with the provision of advertising space and are considered a distinct performance obligation. Production revenue is recognized over the production period, which is typically very short in duration. Our traditional billboard display and transit display contracts with customers range from four weeks to one year and billing commences at the beginning of the contract term, with payment generally due within 30 days of billing. For the majority of our contracts, transaction prices are explicitly stated. Any contracts with transaction prices that contain multiple performance obligations are allocated primarily based on a relative standalone selling price basis. Deferred revenues primarily consist of revenues collected in advance of being earned. For all revenue sources, we evaluate whether we should be considered the principal (i.e., report revenues on a gross basis) or an agent (i.e., report revenues on a net basis). We are considered the principal in our arrangements and report revenues on a gross basis, wherein the amounts billed to customers are recorded as revenues, and amounts paid to municipalities, transit operators and suppliers are recorded as expenses. We are considered the principal because we control the advertising space before and after the contract term, are primarily responsible to our customers, have discretion in pricing and typically have inventory risk. For space provided to advertisers through the use of an advertising agency whose commission is calculated based on a stated percentage of gross advertising spending, our Revenues are reported net of agency commissions.
Concentration of Credit Risk	Concentration of Credit Risk— In the opinion of management, credit risk is limited due to the large number of customers and advertising agencies utilized. We perform credit evaluations on our customers and agencies and believe that the allowances for doubtful accounts are adequate.
Billboard Property Lease and Transit Franchise Expenses	Billboard Property Lease and Transit Franchise Expenses —Our billboards are primarily located on leased real property. Lease agreements are negotiated for varying terms ranging from one month to multiple years, most of which provide renewal options. Lease costs consist of a fixed monthly amount and certain lease agreements also include contingent rent based on the revenues we generate from the leased site. Property leases are generally paid in advance for periods ranging from one The fixed component of lease costs is expensed evenly over the non-cancellable contract term, and contingent rent is expensed as incurred when the related revenues are recognized. Our transit franchise agreements have fixed terms, are typically terminable for convenience at the option of the governmental entity (other than with respect to the MTA), and generally provide for payments to the governmental entity based on a percentage of revenues generated under the contract and/or a guaranteed minimum annual payment. The costs which are determined based on a percentage of revenues are expensed as incurred when the related revenues are recognized, and the guaranteed minimum annual payment is expensed over the contract term.
Direct Lease Acquisition Costs	Direct Lease Acquisition Costs— Variable commissions directly associated with billboard revenues are amortized on a straight-line basis over the related customer lease term, which generally ranges from four weeks to one year. Amortization of direct lease acquisition costs are presented within Selling General and Administrative expenses (“ SG&A
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions— The assets and liabilities of foreign subsidiaries are translated at exchange rates in effect at the balance sheet date, while results of operations are translated at average exchange rates for the respective periods. Any gain or loss on translation is included within other comprehensive income (loss) and Accumulated other comprehensive loss on our Consolidated Statement of Financial Position. Foreign currency transaction gains and losses are included in Other income (loss), net, on the Consolidated Statements of Operations.
Income Taxes	Income Taxes —As a REIT, we generally will not be subject to federal, state and local 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, and certain of our foreign subsidiaries, as taxable REIT subsidiaries (“TRSs”). As such, the taxable income of our TRSs will be subject to federal, state and local income taxation at regular corporate rates. Income taxes are accounted for under the asset and liability method of accounting. Deferred income tax assets and liabilities are recognized for the estimated future tax effects of temporary differences between the financial statement carrying amounts and their respective tax basis. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax assets will not be realized. We have applied the FASB’s guidance relating to uncertainty in income taxes recognized. Under this guidance we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The tax benefits recognized from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The guidance on accounting for uncertainty in income taxes also provides guidance on de-recognition, classification, interest and penalties on income taxes, and accounting in interim periods.
Asset Retirement Obligation	Asset Retirement Obligation —An asset retirement obligation is established for the estimated future obligation, upon termination or non-renewal of a lease, associated with removing structures from the leased property and, when required by the contract, the cost to return the leased property to its original condition. These obligations are recorded at their present value in the period in which the liability is incurred and are initially recorded as part of the related assets’ carrying value. Accretion of the liability is recognized in selling, general and administrative expenses and the capitalized cost is depreciated over the expected useful life of the related asset.
Stock-based Compensation	Stock-based Compensation —We measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized over the vesting period during which an employee is required to provide service in exchange for the award.

Reconciliation of Revenue and Operating Measures from Segments to Consolidated	The following tables set forth our financial performance by segment. We present Operating income (loss) before Depreciation , Amortization , Net (gain) loss on dispositions, Stock-based compensation and Impairment charges (“Adjusted OIBDA”) as the primary measure of profit and loss for our operating segments. Adjusted OIBDA margin is a secondary measure utilized to measure performance of our operating segments. Our chief operating decision maker utilized Adjusted OIBDA and Adjusted OIBDA margin in evaluating our operating performance and planning and forecasting future periods, as each is an important indicator of our operational strength and business performance. We believe these measures highlight operational trends and provide an important perspective on operational performance across periods.

Out-of-period adjustment				Revision of Previously Issued Financial InformationIn the third quarter of 2024, we identified an error related to the accounting for noncontrolling interests in our consolidated joint ventures, which include buy/sell clauses. The error related to the appropriate classification of these noncontrolling interests as redeemable and recognition of these redeemable noncontrolling interests at the maximum redemption value for each period. The Company assessed the materiality of the error on its previously issued financial statements in accordance with the SEC’s Staff Accounting Bulletin (“SAB”) No. 99 and SAB No. 108 and concluded that the amount was not material, individually or in the aggregate, to any of its previously issued financial statements, but would have been material to certain of our financial statements in the current period. Accordingly, we have revised our previously issued financial information. All relevant prior period amounts affected by these revisions have been corrected in the applicable Notes to the Consolidated Financial Statements, as appropriate. Any prior periods not presented herein may be revised in future filings to the extent necessary. (See Note 20. Revised Consolidated Financial Information.)As previously disclosed, for the three months ended March 31, 2023, the Company recorded an out-of-period adjustment relating to variable billboard property lease costs and accrued lease and franchise costs in 2022, resulting in a $5.2 million increase in operating expenses for the three months ended March 31, 2023. The Company assessed the materiality of the amount reflected in this adjustment on its previously issued financial statements in accordance with the SEC’s SAB No. 99 and SAB No. 108 and concluded that the amount was not material, individually or in the aggregate, to any of its previously issued financial statements. In the third quarter of 2024, we voluntarily revised our previously issued financial information to reflect the out-of-period adjustment amount. Prior periods not presented herein will be voluntarily revised, as applicable, in future filings. (See Note 20. Revised Consolidated Financial Information.)The impact of the revisions have been reflected throughout the Consolidated Financial Statements, including the applicable Notes to the Consolidated Financial Statements, as appropriate.

Stockholders' Equity, Reverse Stock Split					To offset the dilutive impact of the Special Dividend, on January 8, 2025, we announced a 1-for-1.024549 reverse stock split on our common stock, such that every common stockholder would receive one share of common stock for every 1.024549 shares of common stock held by such common stockholder outstanding as of January 17, 2025 (the “Reverse Stock Split”). The Reverse Stock Split took effect on January 17, 2025. As a result of the Reverse Stock Split, the number of outstanding shares of common stock as of January 17, 2025, was reduced from 170,061,181 to 165,986,229, which is substantially similar to the outstanding shares of common stock prior to the Special Dividend. The Company’s authorized shares of common stock and par value of each share of common stock remained unchanged. All shares of the Company’s common stock included in these Consolidated Financial Statements have been retroactively adjusted as though the Reverse Stock Split has been effected prior to all periods presented.
