In addition, Pearson plc, Interactive Data’s majority stockholder, has formally approved the transaction.

Under the agreement, Interactive Data’s stockholders will receive $33.86 in cash for each share of Interactive Data common stock they own.

Completion of the transaction is expected to occur by the end of the third quarter of 2010, following regulatory approvals and other customary closing conditions.

Rona Fairhead, chairman of Interactive Data’s board of directors, said: “This transaction enables Interactive Data’s shareholders to realize substantial value and provides the company with partners who are committed to supporting its global expansion. Interactive Data has an outstanding team of more than 2,400 people and the Board thanks them sincerely for their skill and commitment in serving our customers and building the Company over many years. With the support of Silver Lake and Warburg Pincus, I am confident that Interactive Data will take full advantage of its strong market position and the changes in technology and regulations that are shaping its industry.”

“Today’s announcement is a very positive outcome for stockholders, customers and employees,” said Ray D’Arcy, Interactive Data’s president and chief executive officer. “Pearson has been a valuable, supportive partner to Interactive Data over the years as we expanded our business globally. Transitioning our ownership structure will mark an exciting, new chapter in Interactive Data’s development. With the backing of Silver Lake and Warburg Pincus, we look forward to accelerating our momentum and further enhancing our capabilities, delivery platforms and technical infrastructure. I believe that the collective experience and expertise of these firms in the financial services and technology sectors will enable us to take our Company to a new level in terms of our size, capabilities and stature in the industry.”

Mike Bingle, Managing Director of Silver Lake, commented, “Interactive Data is an innovative leader in the information services industry, and our investment is a compelling addition to Silver Lake’s portfolio of premier technology-enabled companies. Interactive Data and the services it provides are essential to enhancing efficiency and transparency in the flow of global financial data.”

Joe Osnoss, Managing Director of Silver Lake, added, “Silver Lake and Warburg Pincus both have significant experience investing in market-leading companies at the intersection of financial services and technology. Interactive Data is particularly well-positioned as a global financial technology growth platform, and we expect a strong partnership between our firms and Interactive Data’s customers and employees in pursuing this opportunity.”

Jim Neary, Managing Director at Warburg Pincus, commented, “This acquisition aligns well with our financial technology and information investment theses; Interactive Data is a market leader that provides critical data to its customers. We look forward to partnering with them, and Silver Lake, as the Company continues to grow and expand its footprint.”

Cary Davis, Managing Director at Warburg Pincus, added, “Interactive Data, an independent source of pricing data, is regarded as ‘the gold standard’ by its customers. The information provided by Interactive Data has increased in importance following the market crisis, and will continue to do so as the demand for transparency intensifies.”
