CBS CORPORATION REPORTS SECOND QUARTER 2013 RESULTS

Revenues of $3.7 Billion, Up 11%

OIBDA of $952 Million, Up 5%

Operating Income of $838 Million, Up 6%

Diluted EPS of $.76, Up 12%

NEW YORK, July 31, 2013 – CBS Corporation (NYSE: CBS.A and CBS) today reported its highest ever quarterly profits for the second quarter ended June 30, 2013.

“CBS’s remarkable momentum continues to build,” said Sumner Redstone, Executive Chairman, CBS Corporation. “This is a Company built for long-term success, and I know Les and his team will continue to execute in the quarters and years to come.”

“Double-digit revenue growth—and the best quarterly profits we’ve ever had—add up to a phenomenal quarter for CBS,” said Leslie Moonves, President and Chief Executive Officer, CBS Corporation. “Across the board, CBS’s world-class content continues to drive our results. From Under the Dome, which is changing the face of summer programming on network television, to Ray Donovan, which has refilled the pipeline at Showtime in a big way, new owned content continues to flourish throughout our Company. As a result, our base business is thriving, and our non-advertising revenue sources are having a bigger impact on our results all the time. Looking ahead, the opportunities to monetize our content are more exciting than ever. In addition, we are well on our way to completing our strategic initiatives in our Outdoor segment—including the pending sale of our business in Europe and Asia and the separation of our Outdoor Americas business, which is right on track. All of this gives us great confidence in our future, and it’s why we announced last week our largest increase ever to our share repurchase program. We remain committed to returning value to our shareholders, and we are certain we can deliver lucrative results for the remainder of this year, next year, and beyond as well.”

Second Quarter 2013 Results

Revenues of $3.70 billion for the second quarter of 2013 grew 11% from $3.33 billion in the same prior-year period, with increases in each revenue type. The growth was led by a 22% increase in content licensing and distribution revenues, which was driven by licensing agreements for digital streaming and international syndication. Advertising revenues were up 5%, partly from the timing of the semifinals of the NCAA Division I Men’s Basketball Championship (“NCAA Tournament”), which aired during the second quarter in 2013 versus the first quarter in 2012, as well as increases in underlying network advertising. Affiliate and subscription fee revenues rose 18%, reflecting the impact of a pay-per-view boxing event, and growth from retransmission revenues and fees from CBS Television Network affiliated television stations.

Operating income before depreciation and amortization (“OIBDA”) of $952 million increased 5% in the second quarter of 2013 from $911 million for the same prior-year period, with growth in every operating segment. Operating income of $838 million increased 6% from $792 million in the second quarter of 2012. The OIBDA and operating income growth was primarily driven by the higher revenues, which were partially offset by increased investment in television content and higher sports programming costs from the timing of the semifinals of the NCAA Tournament.

Net earnings from continuing operations were $476 million for the second quarter of 2013, up from $452 million for the same prior-year period. Diluted earnings per share from continuing operations increased 12% to $.76 from $.68 for the second quarter of 2012, reflecting the Company’s operating income growth, lower interest expense from the Company’s 2012 debt refinancing activities, and lower weighted average shares outstanding as a result of the Company’s ongoing share repurchase program.

Reconciliations of non-GAAP measures to reported results are included at the end of this earnings release.

Free Cash Flow, Balance Sheet and Liquidity

During the second quarter of 2013, the Company made discretionary pension contributions of $150 million to prefund its qualified plans. Free cash flow for the quarter, which includes these contributions, was $414 million compared with $564 million for the same prior-year period. For the first half of 2013, free cash flow was $990 million compared with $1.18 billion for the first half of 2012. The Company generated operating cash flow from continuing operations of $1.07 billion for the six months ended June 30, 2013, versus $1.27 billion for the comparable prior-year period.

Also during the second quarter of 2013, the Company repurchased 10.4 million shares of CBS Corp. Class B Common Stock, including 6.1 million shares that were repurchased on the open market for $296 million and 4.3 million shares that were delivered upon the settlement of the accelerated share repurchase transaction that was initiated during the first quarter of 2013. On July 25, 2013, the Company announced that it expanded its share repurchase program to a total availability of $6 billion, an increase of $5.1 billion. Since the share repurchase program was initiated in January 2011, through June 30, 2013, the Company has repurchased 112.2 million shares of its Class B Common Stock for $3.75 billion.

At June 30, 2013, the Company’s debt outstanding was $6.42 billion, and its cash on hand was $282 million.

Entertainment (CBS Television Network, CBS Television Studios, CBS Global Distribution Group, CBS Films, and CBS Interactive)

Entertainment revenues of $2.01 billion for the second quarter of 2013 increased 18% from $1.71 billion for the same prior-year period. This increase was driven by higher revenues from the licensing of television programming for digital streaming and international syndication, higher advertising revenues, and growth in network affiliation fees. The increase in advertising revenue reflects 11% growth at the CBS Television Network and increases at CBS Interactive. The timing of the semifinals of the NCAA Tournament contributed seven percentage points to the CBS Television Network’s advertising growth.

Entertainment OIBDA for the second quarter of 2013 of $429 million increased 1% from $426 million for the same prior-year period, as the revenue growth was offset by increased investment in television content and higher sports programming costs from the timing of the semifinals of the NCAA Tournament.

Cable Networks (Showtime Networks, CBS Sports Network, and Smithsonian Networks)

Cable Networks revenues for the second quarter of 2013 increased 16% to $518 million from $446 million for the same prior-year period. The growth was driven by revenues from a pay-per-view boxing event, higher revenues from the licensing of Showtime original series for digital streaming, and higher affiliate revenues. The increase in affiliate revenues reflects growth in rates and subscriptions at Showtime Networks (which includes Showtime, The Movie Channel, and Flix), CBS Sports Network, and Smithsonian Networks.

Cable Networks OIBDA for the second quarter of 2013 increased 9% to $207 million from $190 million for the same prior-year period, primarily a result of the revenue growth. The OIBDA increase was partially offset by higher sports programming costs, including the pay-per-view boxing event, as well as higher advertising and marketing costs to promote Showtime series.

Publishing (Simon & Schuster)

Publishing revenues of $189 million for the second quarter of 2013 were comparable with the same prior-year period, as continued growth in digital book sales was offset by lower print book sales. Digital book sales increased 39% from the same prior-year period and represented 29% of Publishing’s total revenues, compared with 21% for the second quarter of 2012. Best-selling titles in the second quarter included Happy, Happy, Happy by Phil Robertson and City of Bones by Cassandra Clare.

Publishing OIBDA for the second quarter of 2013 increased $12 million to $21 million from $9 million for the same prior-year period, as the more profitable digital book sales continued to grow and last year’s second quarter included a charge related to a legal matter.

5

Local Broadcasting (CBS Television Stations and CBS Radio)

Local Broadcasting revenues for the second quarter of 2013 decreased 1% to $698 million from $704 million for the same prior-year period. CBS Television Stations revenues decreased 1%, primarily reflecting lower political advertising. CBS Radio revenues remained flat compared with the same prior-year period, as the benefit of the new CBS Sports Radio network was offset by the impact of radio station dispositions in 2012.

Local Broadcasting OIBDA for the second quarter of 2013 increased 3% to $255 million from $248 million for the same prior-year period, principally because of lower programming and production costs.

Outdoor Americas (CBS Outdoor)

Outdoor Americas revenues for the second quarter of 2013 increased slightly to $335 million from $334 million for the same prior-year period, as growth in the U.S. was offset by lower revenues in Canada and Mexico. Revenues in the U.S. grew 2%, driven by a 5% increase in the billboard business.

Outdoor Americas OIBDA for the second quarter of 2013 rose 4% to $107 million from $103 million for the same prior-year period. The increase was driven by the revenue growth and lower costs associated with the renewal of a transit contract.

Corporate

Corporate expenses before depreciation for the second quarter of 2013 increased $2 million to $67 million from $65 million for the same prior-year period, reflecting higher costs associated with the increase in the Company’s stock price and the conversion of Outdoor Americas to a Real Estate Investment Trust (“REIT”). These increases were partially offset by lower pension and postretirement benefit costs, primarily reflecting the benefit from prefunding pension plans in 2012 and the favorable performance of pension plan assets in 2012.

Outdoor Transactions

In July 2013, the Company entered into an agreement with an affiliate of Platinum Equity for the sale of the Company’s outdoor advertising business in Europe and Asia for approximately $225 million. The transaction is expected to be completed during 2013, subject to customary closing conditions. The Company’s outdoor business in Europe and Asia has been presented as a discontinued operation.

During the first quarter of 2013, the Company submitted a private letter ruling request with the Internal Revenue Service to qualify its Outdoor Americas business as a REIT. During the second quarter of 2013, a preliminary registration statement was filed with the Securities and Exchange Commission for the proposed initial public offering of the common stock of CBS Outdoor Americas Inc. The Company currently expects to dispose of the shares of CBS Outdoor Americas Inc. that it will own after the completion of the offering. These actions are subject to customary approvals and market conditions.

Segment Operating Income (Loss) Before Depreciation and Amortization (“OIBDA”) and Adjusted OIBDA

The Company presents Segment OIBDA as the primary measure of profit and loss for its operating segments in accordance with FASB guidance for segment reporting.

The following tables set forth the Company’s OIBDA for the three and six months ended June 30, 2013 and 2012 and adjusted OIBDA for the six months ended June 30, 2012. The Company defines OIBDA as net earnings (loss) adjusted to exclude the following line items presented in its Consolidated Statements of Operations: Net earnings (loss) from discontinued operations; Equity in earnings (loss) of investee companies, net of tax; Provision for income taxes; Other items, net; Gain on early extinguishment of debt; Interest income; Interest expense; and Depreciation and amortization. The Company defines “Adjusted OIBDA” as OIBDA excluding restructuring and impairment charges. For each individual operating segment, Adjusted OIBDA is also known as “Segment OIBDA”.

The Company uses Adjusted OIBDA (or Segment OIBDA for each segment), as well as Adjusted OIBDA margin, to, among other things, evaluate the Company’s operating performance, to value prospective acquisitions and as one of several components of incentive compensation targets for certain management personnel. These measures are among the primary measures used by management for planning and forecasting of future periods, and they are important indicators of the Company’s operational strength and business performance because they provide a link between profitability and operating cash flow. The Company believes these measures are relevant and useful for investors because they allow investors to view performance in a manner similar to the method used by the Company’s management, help improve investors’ understanding of the Company’s operating performance, and make it easier for investors to compare the Company’s results with other companies that have different financing and capital structures or tax rates. In addition, these are among the primary measures used externally by the Company’s investors, analysts and industry peers for purposes of valuation and for the comparison of the Company’s operating performance to other companies in its industry.

Because Adjusted OIBDA is not a measure of performance calculated in accordance with accounting principles generally accepted in the United States (“GAAP”), it should not be considered in isolation of, or as a substitute for, net earnings (loss) as an indicator of operating performance. Adjusted OIBDA, as the Company calculates it, may not be comparable to similarly titled measures employed by other companies. In addition, this measure does not necessarily represent funds available for discretionary use and is not necessarily a measure of the Company’s ability to fund its cash needs. As Adjusted OIBDA excludes certain financial information that is included in net earnings (loss), the most directly comparable GAAP financial measure, users of this financial information should consider the types of events and transactions which are excluded. The Company provides the following reconciliations of Adjusted OIBDA to operating income and net earnings (loss), the most directly comparable amounts reported under GAAP. In addition, the following tables also provide reconciliations of Segment OIBDA for each segment to such segment’s operating income (loss).
