We Positioned Millennial Media to Leverage Shifts in Mobile Advertising 7 Managed Services Managed Services and Programmatic Ad Buying / Selling Smartphones Every Device: Phones, Tablets, PCs & TVs Device Driven by Content Adjacency Mobile Data Required for Audience Targeting Targeting Primarily Banner with Some Rich Media Accelerating Focus on Video, Rich Media and Native Ad Formats Previous Market Dynamics Today & Moving Forward Primarily U.S. Global Geography Achieving success during these shifts requires a leading data asset

8 Mobile Data is the Key that unlocks the True Digital Profile Data is the new content – In mobile, data-driven audiences are far more valuable to advertisers than mere content adjacency Mobile specific technology is required to aggregate mobile data and draw insights – online technology lacks effectiveness Millennial Media has built its data asset over seven years of mobile only focus

How Millennial Media Differentiates 9 While Google advertising operates across operating systems, Google owns its own operating system, app store and mobile device manufacturer. There is an industry perception that Google mobile ad products are focused primarily on Android devices. Pending MMX launch and Jumptap exchange buying. Pro forma for Jumptap acquisition. ~ Some publishers do fit the category and some do not.
