On March 25, 2015, two wholly owned subsidiaries of OUTFRONT Media Inc. (the “Company”) commenced an offering (the “Offering”) of an additional $100 million in aggregate principal amount of their existing 5.625% Senior Notes due 2024 (the “Notes”), to qualified institutional buyers and non-U.S. persons pursuant to Rule 144A and Regulation S, as applicable, under the Securities Act of 1933, as amended (the “Securities Act”).

In connection with the Offering, the Company provided potential investors with a preliminary offering memorandum, dated March 25, 2015 (the “Preliminary Offering Memorandum”). The Preliminary Offering Memorandum contains unaudited pro forma condensed consolidated financial information and notes thereto relating to the Company’s acquisition of certain outdoor advertising businesses of Van Wagner Communications, LLC (the “Pro Forma Financial Information”). The Pro Forma Financial Information is included in Exhibit 99.1 hereto and is incorporated by reference into this Item 7.01.

This Current Report on Form 8-K does not constitute an offer to sell or the solicitation of an offer to buy the Notes and shall not constitute an offer, solicitation or sale of the Notes in any jurisdiction in which such offering, solicitation or sale would be unlawful. The Notes have not been registered under the Securities Act, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

The information contained in this Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.1, is being furnished pursuant to Item 7.01. This information shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section, or incorporated by reference into any filing under the Securities Act or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

Cautionary Statement Concerning Forward-Looking Statements

The Company has made statements in this Current Report on Form 8-K that are forward-looking statements within the meaning of the federal securities laws, including the Private Securities Litigation Reform Act of 1995. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “could,” “would,” “may,” “might,” “will,” “should,” “seeks,” “likely,” “intends,” “plans,” “projects,” “predicts,” “estimates,” “forecast” or “anticipates” or the negative of these words and phrases or similar words or phrases that are predictions of or indicate future events or trends and that do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions relating to the Offering, the Company’s real estate investment trust (“REIT”) status and its capital resources, portfolio performance and results of operations. Forward-looking statements involve numerous risks and uncertainties and you should not rely on them as predictions of future events. Forward-looking statements depend on assumptions, data or methods that may be incorrect or imprecise and may not be able to be realized. The Company does not guarantee that the transactions and events described will happen as described (or that they will happen at all). The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: the Company’s ability to consummate the Offering on favorable terms, or at all; the use of the net proceeds from the Offering; declines in advertising and general economic conditions; competition; government regulation; the Company’s inability to increase the number of digital advertising displays in its portfolio; taxes, fees and registration requirements; the Company’s ability to obtain and renew key municipal concessions on favorable terms; decreased government compensation for the removal of lawful billboards; content-based restrictions on outdoor advertising; environmental, health and safety laws and regulations; seasonal variations; acquisitions and other strategic transactions that the Company may pursue could have a negative effect on its results of operations; time and resources to comply with rules and regulations as a stand-alone public company; incremental costs incurred as a stand-alone public company; dependence on the Company’s management team and advertising executives; the ability of the Company’s board of directors to cause it to issue additional shares of stock without stockholder approval; certain provisions of Maryland law may limit the ability of a third party to acquire control of the Company; the Company’s rights and the rights of its stockholders to take action against its directors and officers are limited; the Company’s substantial indebtedness; restrictions in the agreements governing the Company’s indebtedness; incurrence of additional debt; interest rate risk exposure from the Company’s variable-rate indebtedness; the Company’s ability to generate cash to service its indebtedness; hedging transactions; establishing an operating partnership; asset impairment charges for goodwill; diverse risks in the Company’s international business; a breach of the Company’s security measures; failure to comply with regulations regarding privacy and data protection; failing to establish in a timely manner “OUTFRONT” as an independently recognized brand name with a strong reputation; the financial information included in the Company’s filings with the Securities and Exchange Commission (the “SEC”) may not be a reliable

indicator of its future results; cash available for distributions; legislative, administrative, regulatory or other actions affecting REITs, including positions taken by the Internal Revenue Service (the “IRS”); the Company’s failure to remain qualified to be taxed as a REIT; REIT ownership limits; REIT distribution requirements; availability of external sources of capital; the Company may face other tax liabilities even if it remains qualified to be taxed as a REIT; complying with REIT requirements may cause the Company to liquidate investments or forgo otherwise attractive opportunities; the Company’s ability to contribute certain contracts to a taxable REIT subsidiary (“TRS”); the Company’s planned use of TRSs may cause it to fail to remain qualified to be taxed as a REIT; the Company’s ability to hedge effectively; failure to meet the REIT income tests as a result of receiving non-qualifying income; even if the Company remains qualified to be taxed as a REIT, and it sells assets, it could be subject to tax on any unrealized net built-in gains in the assets held before electing to be treated as a REIT; the IRS may deem the gains from sales of the Company’s outdoor advertising assets to be subject to a 100% prohibited transaction tax; the Company’s lack of an operating history as a REIT; the Company may not be able to engage in desirable strategic or capital-raising transactions as a result of its separation from CBS Corporation, and it could be liable for adverse tax consequences resulting from engaging in significant strategic or capital-raising transactions; and other factors described in the Company’s filings with the SEC, including but not limited to the section entitled “Risk Factors” in its Annual Report on Form 10-K for the year ended December 31, 2014. All forward-looking statements in this Current Report on Form 8-K apply as of the date of this report or as of the date they were made and, except as required by applicable law, the Company disclaims any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors of new information, data or methods, future events or other changes.
