CBS CORPORATION UPDATES 2008 GUIDANCE

NEW YORK, NEW YORK, October 10, 2008 — CBS Corporation (NYSE: CBS.A and CBS) today revised its business outlook for the full year 2008.

The continued economic slowdown in the United States has adversely affected advertising revenues across the Company’s businesses, primarily at the local level, and the effects of the current financial crisis are likely to cause further declines in advertising spending. As a result of these market conditions, the Company is revising its 2008 full year business outlook for both adjusted operating income before depreciation and amortization (“OIBDA”) and adjusted operating income to a decline of mid-teens versus 2007.

The Company said that, based on preliminary information, its third quarter performance is expected to reflect revenue growth of approximately 3% over the comparable period last year, led by higher syndication revenue and recent acquisitions. Further, the Company now expects to report adjusted diluted earnings per share of approximately $.42 to $.44 for the third quarter of 2008, compared to $.51 for the third quarter of 2007.

In addition, as a result of these recent adverse market conditions, the Company is currently performing an interim impairment test on its existing goodwill, other indefinite lived intangible asset balances and investments. Based on preliminary results, the Company expects to incur a non-cash impairment charge of approximately $14 Billion, in the third quarter of 2008 to reduce the carrying value of goodwill, intangible assets related to FCC licenses and investments.

The Company’s business outlook excludes stock-based compensation expense, restructuring charges, impairment charges and the impact of acquisitions and dispositions.

The Company continues to generate significant free cash flow and expects to maintain its current dividend policy. CBS plans to provide additional information regarding its third quarter results and business outlook during its regular quarterly conference call October 30, at 8:30 AM (ET), following the release of its earnings announcement.
