WESTLAKE VILLAGE, CA – August 3, 2004 – ValueClick, Inc. (Nasdaq: VCLK), the single-source provider of media, technology and services across all major interactive marketing channels, today announced that it has agreed to acquire privately-held Pricerunner AB, a leading provider of online comparison shopping services in Europe. Pricerunner.com is the most popular comparison shopping site in Sweden and the third most popular site in the United Kingdom, enabling its users to search for and compare 170,000 products and 1,200 retailers online before they buy.

The addition of Pricerunner will expand ValueClick’s suite of performance-based online marketing solutions into the high-growth area of comparison shopping – the most commerce-oriented form of search – and will expand ValueClick’s presence in Europe. Pricerunner will increase ValueClick’s ability to participate in the expected growth in Europe’s online retail sales, which Forrester Research forecasts will grow from 40 billion Euros in 2004 to 167 billion Euros in 2009 – an annual growth rate of 33 percent.

Pricerunner currently operates comparison shopping sites in the United Kingdom and Sweden, and plans to expand in France and Germany during 2004. Pricerunner generates the majority of its revenue through a lead-based model, where retailers pay Pricerunner on a cost-per-click basis for online consumers that Pricerunner delivers to the retailer’s Website.

Under the terms of the agreement, ValueClick will acquire all outstanding equity interests in Pricerunner for an adjusted purchase price of approximately $29.0 million, including cash and approximately 263,000 shares of ValueClick common stock to be issued to three management shareholders of Pricerunner. In the transaction, ValueClick has agreed to provide additional cash and stock consideration totaling up to $6.0 million, contingent upon Pricerunner exceeding certain performance milestones. The transaction has been approved by the shareholders of Pricerunner and by ValueClick’s Board of Directors, subject to customary closing conditions. The transaction is expected to close in August 2004. Pricerunner will be integrated into ValueClick’s European division.

“We have been looking to add comparison shopping services as part of our strategic growth plan, and in Pricerunner we have found an established partner that will help us take our first step in this rapidly-growing and profitable area of performance-based online marketing,” said James Zarley, chairman and chief executive officer of ValueClick. “Comparison shopping is a strategic fit with our media, affiliate marketing and search offerings, and we look forward to working with Pricerunner and helping them expand their presence in Europe.”
