comScore to Acquire AdXpose, a Leader in Ad Verification, Optimization and Brand Safety

Acquisition Improves comScore’s End-to-End Media Planning and Ad Effectiveness Measurement Capabilities

RESTON, VA, August 3, 2011 – comScore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced a definitive agreement to acquire AdXpose®, the market-leading verification and optimization company, for total consideration of $22 million in a primarily stock-based transaction. Headquartered in Seattle with offices in New York, AdXpose provides advertisers and publishers with greater transparency and confidence in the quality, safety, and performance of their digital advertising campaigns by allowing them to verify and optimize billions of campaign data points captured in real-time. The actionable optimization metrics captured by AdXpose solutions help its customers realize increased ROI, more profitable margins, and measurable ad effectiveness.

“We are excited to welcome the AdXpose team to comScore,” said Dr. Magid Abraham, comScore President & CEO. “In just a few short years, AdXpose has demonstrated clear technology leadership with their leading ad verification and optimization analytics solutions, which are highly complementary to comScore’s existing ad effectiveness product suite. Through the integration of these capabilities, comScore will be able to further its mission to develop the most comprehensive end-to-end suite of digital advertising analytics. With audience-buying becoming increasingly prevalent in digital media planning today, there is a growing demand for analytical tools that enable greater transparency and accountability in ad delivery. The AdXpose technology will enable comScore to bring this important dimension of advertising effectiveness to its clients.”

“The AdXpose team is thrilled to join comScore to help take our ad verification and optimization solutions to the next level,” said Kirby Winfield, AdXpose President & CEO. “comScore is at the center of the digital media planning universe, and in our view this business combination represents the most effective way to introduce our capabilities to a much broader footprint of advertisers and agencies. In addition, the ability to leverage comScore’s existing ad effectiveness capabilities will allow us to bring new value to the campaign planning and verification process.”

comScore expects the transaction to close in approximately two weeks, subject to customary closing conditions, and does not anticipate a meaningful impact on revenue in 2011.
