Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

On April 2, 2014, we completed our Initial Public Offering (“IPO”). On April 16, 2014, CBS Corporation (“CBS”) received a favorable private letter ruling from the Internal Revenue Service (the “IRS”) with respect to certain issues relevant to our ability to qualify to be taxed as a real estate investment trust (“REIT”). On July 16, 2014, CBS completed an exchange offer (the “CBS Exchange Offer”), and in connection with the CBS Exchange Offer, CBS disposed of all of its shares of our common stock. On July 16, 2014, we ceased to be a member of the CBS consolidated tax group, and on July 17, 2014, we began operating in a manner that will allow us to qualify as a REIT for U.S. federal income tax purposes for the tax year commencing July 17, 2014, and ending December 31, 2014. On July 20, 2014, we entered into the Membership Interest Purchase Agreement, by and among us, CBS Outdoor LLC, Van Wagner Communications, LLC (“Van Wagner”), Van Wagner Twelve Holdings, LLC and Richard M. Schaps (the “Purchase Agreement”), pursuant to which we agreed to acquire certain outdoor advertising businesses (the “Acquired Business”) from Van Wagner for $690.0 million in cash, subject to working capital and other adjustments (the “Acquisition”).

The following unaudited pro forma condensed consolidated statements of operations and balance sheet, as well as the calculations of pro forma funds from operations (“FFO”) and adjusted funds from operations (“AFFO”), have been adjusted to reflect the IPO, our REIT election, the one-time dividend to our stockholders to be declared on or prior to December 31, 2014 to distribute accumulated earnings and profits allocated to us by CBS in connection with our separation (the “Separation”) from CBS (the “Purging Distribution”), the consummation of the Acquisition and the issuance of $150.0 million aggregate principal amount of 5.250% Senior Notes due 2022 and $450.0 million aggregate principal amount of 5.875% Senior Notes due 2025 and borrowings of $40.0 million under our $425.0 million revolving credit facility maturing in 2019 (the “Revolving Credit Facility”) to finance a portion of the consideration for the Acquisition (the “Acquisition Borrowings”). The unaudited pro forma condensed consolidated balance sheet at June 30, 2014 is presented as if each of these events, except for the IPO, which was completed on April 2, 2014, occurred at June 30, 2014. The unaudited pro forma condensed consolidated statements of operations and the calculations of unaudited pro forma FFO and AFFO for the six months ended June 30, 2014 and the year ended December 31, 2013 are presented as if each of these events had occurred on January 1, 2013 and also include pro forma adjustments to reflect a full period of incremental costs associated with operating as a stand-alone public company, interest expense relating to the issuance of $400.0 million aggregate principal amount of 5.250% Senior Notes due 2022 and $400.0 million aggregate principal amount of 5.625% Senior Notes due 2024 and borrowings under our $800.0 million term loan due in 2021 (the “Term Loan” and, together with the Revolving Credit Facility, the “Senior Credit Facilities”) on January 31, 2014 (the “Formation Borrowings”) and dilution from the conversion of outstanding CBS restricted stock units (“RSUs”) to our RSUs in connection with the IPO and the conversion of outstanding stock options to purchase CBS Class B common stock to our stock options to purchase our common stock (the “Stock Option Conversion”) in connection with the Separation.

The pro forma information is presented both before and after the Purging Distribution. In connection with the Purging Distribution, we expect to pay a combination of cash and shares of our common stock to our stockholders in the form of a dividend.

The unaudited pro forma condensed consolidated financial statements are based upon our historical consolidated financial statements, as well as those of the Acquired Business, for each period presented. In the opinion of management, all adjustments and/or disclosures necessary for a fair statement of the pro forma data have been made. These unaudited pro forma condensed consolidated financial statements are presented for illustrative purposes only and do not necessarily reflect what our results of operations and financial condition would have been had the transactions referred to above occurred on such dates. Accordingly, such information should not be relied upon as an indicator of our future performance, financial condition or liquidity.

NOTES TO CBS OUTDOOR AMERICAS INC. UNAUDITED PRO FORMA

CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1) INITIAL PUBLIC OFFERING

On April 2, 2014, we completed an IPO of 23,000,000 shares of our common stock, representing 19% of our outstanding common stock, for $28.00 per share, for total net proceeds after underwriting discounts and commissions, of $615.0 million. On July 16, 2014, CBS completed the CBS Exchange Offer in which 97,000,000 shares of our common stock that were owned by CBS were exchanged for shares of CBS Class B common stock. In connection with the IPO and the CBS Exchange Offer, non-vested CBS RSUs and stock options held by our employees were converted into non-vested Company RSUs and options. The number of RSUs and options were converted to preserve the intrinsic value of the award at the time of conversion. Weighted average shares outstanding on a pro forma basis reflect the impact of the IPO, the CBS Exchange Offer and conversion of share-based compensation awards as if all shares and awards were outstanding since January 1, 2013.

2) ACQUISITION BORROWINGS AND INTEREST

In connection with the Acquisition, we expect to incur indebtedness of $640 million, consisting of the $600 million in notes from this offering and a draw down of $40 million from our Revolving Credit Facility. The adjustment to “Other assets” reflects estimated deferred financing costs associated with the Acquisition Borrowings.

Interest expense is adjusted by $24.8 million and $55.8 million for the six months ended June 30, 2014 and 2013, respectively, and $111.5 million for the year ended December 31, 2013 to reflect interest for the entire period related to the $1.6 billion of debt incurred on January 31, 2014 in connection with the Formation Borrowings, including the amortization of deferred financing costs and commitment fees on the Senior Credit Facilities and the $640.0 million in Acquisition Borrowings, including deferred financing costs and commitment fees of $11.0 million related to the debt commitment obtained in connection with the Acquisition (see Note 5). The following table presents the pro forma adjustments to interest expense. The pro forma interest expense on the variable-rate Term Loan is calculated using a rate of 3.0%, which was the rate at June 30, 2014. The pro forma interest expense on the Revolving Credit Facility is calculated using an estimated interest rate of 2.75% at June 30, 2014.

An increase or decrease of 1/8% in the interest rate on the Term Loan and Revolving Credit Facility will change annual interest expense by approximately $1.1 million.

3) REIT ELECTION AND INCOME TAXES

On April 16, 2014, CBS received a private letter ruling from the IRS, subject to the terms and conditions therein, with respect to certain issues relevant to our qualification to be taxed as a REIT. On July 16, 2014, we ceased to be a member of the CBS consolidated tax group, and on July 17, 2014, we began operating in a manner that will allow us to qualify as a REIT for U.S. federal income tax purposes for the tax year commencing July 17, 2014, and ending December 31, 2014. So long as we remain qualified to be taxed as a REIT, we generally will not be subject to U.S. federal income tax on our REIT taxable income that we distribute to our stockholders. Even if we qualify for taxation as a REIT, we may be subject to certain U.S. federal, state and local taxes on our income or property, and the income of our TRSs will be subject to taxation at regular corporate rates. The pro forma adjustments for the six months ended June 30, 2014 and 2013, and the year ended December 31, 2013 to “(Provision) benefit for income taxes” of $18.7 million, $17.6 million and $50.8 million, respectively, and to “Equity in earnings of investee companies, net of tax” of $0.4 million, $0.4 million and $1.5 million, respectively, reflect the reversal of the tax provision on taxable income that will no longer be subject to U.S. federal income tax subsequent to our REIT election. Any remaining tax provision mainly reflects taxes on our TRSs. The adjustments at June 30, 2014 to “Prepaid expenses and other current assets” of $23.3 million, “Other assets” of $5.9 million and “Deferred income tax liabilities, net” of $249.2 million reflects the reversal of deferred taxes that will not be realized as a result of our REIT election. The reversal of deferred taxes will be recorded as a one-time benefit to net income and is not reflected in the unaudited pro forma condensed consolidated statement of operations.

The pro forma adjustments to the “(Provision) benefit for income taxes” related to the “Formation Borrowings/IPO and Stand-alone costs” on the unaudited pro forma condensed consolidated statements of operations for the six months ended June 30, 2014 and 2013, and the year ended December 31, 2013 of $4.0 million, $20.8 million and $40.1 million, respectively, are calculated at an effective tax rate of 40.8%, 41.1% and 41.0%, respectively. These adjustments reflect our current tax status as a regular domestic C corporation for U.S. federal income tax purposes.

4) INCREMENTAL STAND-ALONE PUBLIC COMPANY EXPENSES

As a stand-alone public company, we incur incremental expenses for services previously provided by CBS as well as for additional public company expenses that did not apply to us historically. In addition to costs already incurred, we estimate these expenses to be $3.5 million and $13.3 million for the six months ended June 30, 2014 and 2013, respectively, and $23.3 million for the year ended December 31, 2013.

5) ACQUISITION

On July 20, 2014, we entered into the Purchase Agreement, pursuant to which we agreed to acquire the Acquired Business for $690.0 million in cash, subject to working capital and other adjustments. The consummation of the Acquisition is subject to customary closing conditions. The Acquisition is expected to close early in the fourth quarter of 2014.

Allocation of Purchase Price

The allocation presented below represents the effect of recording on a preliminary basis the allocation of the consideration paid for the Acquired Business under the acquisition method of accounting:

The pro forma adjustments to effect the purchase price allocation have been made solely for the purpose of providing pro forma financial information based on current estimates and are subject to revision based on a final determination of fair value, which may not occur for several quarters following the consummation of the Acquisition. The final allocation of the consideration paid will be based upon fair values of assets and liabilities acquired upon closing of the Acquisition, determined based upon a third-party valuation. We expect that the actual purchase price allocation will be different from that which is presented and the difference could be material.

The following tables present detail of the amounts included within the acquisition column of the pro forma financial statements.

Expected Cost Savings Resulting from the Acquisition

Based on current estimates and assumptions, we expect to achieve significant cost savings as a result of the Acquisition, principally by leveraging the scalability of our existing corporate administrative functions and information technology and systems. We estimate that our annualized cost savings will be approximately $28.0 million. These cost savings are not reflected within the unaudited pro forma condensed consolidated financial statements. As a result of conforming accounting policies, we will also reclassify approximately $4.0 million of commission expense from “Selling, general and administrative expenses” to “Amortization.” This adjustment is reflected within the unaudited pro forma condensed consolidated financial statements.

The foregoing future cost savings are based on our estimates and assumptions that, although we consider them reasonable, are inherently uncertain. These expected cost savings are subject to significant business, economic and competitive uncertainties and contingencies, all of which are difficult to predict. As a result, there can be no assurance that these or any other cost savings or synergies will actually be realized.

6) PURGING DISTRIBUTION

In order to comply with certain REIT qualification requirements, we will declare a Purging Distribution by December 31, 2014 and distribute any accumulated earnings and profits attributable to a non-REIT year, including any earnings and profits allocated to us by CBS in connection with the Separation, by January 31, 2015. We expect to pay the Purging Distribution in a combination of cash and our common stock. We currently estimate that the Purging Distribution to be declared by December 31, 2014, will total approximately $500 million, of which approximately 20%, or $100 million, will be paid in cash and approximately 80%, or $400 million, will be paid in shares of our common stock. Based on the closing price of our common stock on September 10, 2014 of $31.49 per share, we currently estimate that 12.7 million additional shares of our common stock will be issued in connection with the Purging Distribution, which will result in a per share dilution to our stockholders. For the six months ended June 30, 2014, the share portion of the Purging Distribution would have reduced AFFO per diluted share by $0.09. For the year ended December 31, 2013, the share portion of the Purging Distribution would have reduced diluted net income per share by $0.08 and AFFO per diluted share by $0.21. The amount of the Purging Distribution in excess of retained earnings of $296.7 million has been reflected as a reduction to “additional paid-in-capital” on the pro forma condensed consolidated balance sheet.

The actual amount of and number of shares of our common stock issued in connection with the Purging Distribution will be calculated as of a future date and could be materially different from current estimates based on a number of factors. Accordingly, these estimates should not be relied upon as an indicator of what the actual cash portion and common stock portion of the Purging Distribution will be.

Following the final payment of the Purging Distribution declared by December 31, 2014, we will pay to CBS, or CBS will pay to us, as applicable, the difference between the actual cash portion of such Purging Distribution and the current estimate of $100 million.

11

7) DIVIDEND

Although U.S. federal income tax law generally requires that a REIT distribute at least 90% of its REIT taxable income (determined before the deduction for dividends paid and excluding any net capital gains), we intend to pay regular quarterly distributions to holders of our common stock in an amount not less than 100% of our REIT taxable income. For the year ended December 31, 2013, if we had elected to be taxed as a REIT, the distribution of 90% of REIT taxable income would have been approximately $142 million. However, as dividends are subject to board authorization, the actual dividend amount could have differed.

12

8) PRO FORMA FFO AND AFFO

The following tables present FFO, AFFO, FFO per weighted average share, and AFFO per weighted average share on a historical basis and on a pro forma basis to adjust net income to reflect additional costs we will incur as a stand-alone public company (See Note 4), interest expense from the Formation Borrowings and the Acquisition Borrowings (See Note 2), and the reduction to our tax provision and deferred taxes associated with our REIT election (See Note 3). Pro forma weighted average shares are adjusted to reflect our IPO and conversion of outstanding stock-based compensation awards (See Note 1), the Acquisition (See Note 5) and the issuance of our common stock in connection with the Purging Distribution (See Note 6). FFO per weighted average share and AFFO per weighted average share are also presented both before and after the Purging Distribution. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for further information about FFO and AFFO.
