ARBITRON INC. REPORTS 2006 SECOND QUARTER FINANCIAL RESULTS
Revenue up 6.2 percent to $74.2 million;
Net income per share (diluted) is $0.24;
Costs and expenses increase due to planned spending on Portable People Meter and ‘Project Apollo’
initiatives and reporting of share-based compensation expense;
Guidance for 2006 year-end unchanged.

NEW YORK, July 20, 2006 – Arbitron Inc. (NYSE: ARB) today announced results for the second quarter ended June 30, 2006.

For the second quarter 2006, the Company reported revenue of $74.2 million, an increase of 6.2 percent over revenue of $69.8 million during the second quarter of 2005.

Planned spending on the Portable People Meter and Project Apollo initiatives and the required expensing of share-based compensation contributed to increased costs and expenses for the second quarter of 21.4 percent, from $55.4 million in 2005 to $67.3 million in 2006.

Earnings before interest and income tax expense (EBIT) for the quarter were $11.9 million, a decrease of 35.8 percent over EBIT of $18.6 million during the comparable period last year.

Income tax expense for the second quarter increased 48.2 percent, from $3.0 million in 2005 to $4.5 million in 2006. The year-to-year difference is due primarily to the $3.9 million reversal of certain reserves for tax contingencies that were recorded during the second quarter of 2005.

Net income for the second quarter decreased by 52.2 percent from $15.4 million in 2005 to $7.4 million in 2006.

Net income per share for the second quarter 2006 was $0.24 (diluted) compared with $0.48 (diluted) for the second quarter 2005.

For the six months ended June 30, 2006, revenue was $159.3 million, an increase of 6.9 percent over the same period last year. EBIT was $41.0 million, compared to $51.3 million in 2005. Net income for the six months was $25.5 million or $0.83 per share (diluted), compared with $35.2 million or $1.11 per share (diluted) during the comparable period last year.

Commenting on the results for the second quarter, Stephen Morris, president and chief executive officer of Arbitron, said: “The radio industry is making continued progress in its transition from diaries to electronic measurement. In the second quarter, we announced a number of Portable People Meter ratings contracts with key radio broadcasters.”

“The broadcasters and agencies who have signed for PPM recognize that no other company has the infrastructure, the experience, and the financial wherewithal to deliver a proven electronic radio measurement system in the rapid timeframe that the radio industry is demanding.”

“In June, at two key industry conferences, we released the first tangible evidence that Project Apollo has the power to reveal the significant consumer targeting capabilities of new and traditional media. The advertisers who sit on the Project Apollo Steering Committee continue to help Arbitron and VNU refine the value proposition of our proposed single-source market research service that would use the Arbitron PPM as its primary media measurement system.”

“Also in the second quarter, we demonstrated our commitment to returning capital to our shareholders as we completed the $70 million stock repurchase program that the Board authorized for 2006,” said Mr. Morris.

Arbitron is also providing guidance on its earnings outlook for the third quarter 2006 and is reaffirming its guidance for the full year 2006.

For the third quarter 2006, Arbitron expects revenue to increase between 6 percent and 8 percent compared to the third quarter of last year. Earnings Per Share (diluted) for the third quarter 2006 is expected to be between $0.59 and $0.62 versus $0.66 in the third quarter 2005. The impact of share-based compensation expense in the third quarter of 2006 is estimated to be approximately $1.4 million, or $0.03 per share (diluted). The balance of the year-over-year reduction is attributable to anticipated incremental spending on PPM initiatives, including Project Apollo, as well as previously announced initiatives to improve research quality.

Arbitron’s year-end 2006 guidance is unchanged. As previously stated, 2006 revenue is expected to increase between 6 percent and 8 percent compared to 2005. Earnings Per Share (diluted) for the year ending December 31, 2006 is expected to be between $1.69 and $1.74.

(3): Earnings before interest and income taxes (EBIT) and earnings before interest, income taxes, depreciation and amortization (EBITDA) are widely used non-GAAP financial measures of operating performance. They are presented as supplemental information that management of Arbitron believes is useful to investors to evaluate the Company’s results because they exclude certain items that are not directly related to the Company’s core operating performance. EBIT is calculated by adding back net interest expense and income tax expense to net income. EBITDA is calculated by adding back net interest expense, income tax expense, depreciation and amortization to net income. EBIT and EBITDA should not be considered as substitutes either for net income, as indicators of Arbitron’s operating performance, or for cash flow, as measures of Arbitron’s liquidity. In addition, because EBIT and EBITDA may not be calculated identically by all companies, the presentation here may not be comparable to other similarly titled measures of other companies.
