WPP, Xaxis, and AppNexus announced today a strategic transaction that will augment AppNexus’ position as the industry’s largest independent ad technology company. Under the terms of the agreement, AppNexus will acquire Xaxis’ premium ad-serving technology, Open AdStream® (OAS), now known as Xaxis For Publishers. In addition, WPP will invest $25 million in AppNexus, adding to the $85 million in funding the company recently raised at a valuation of $1.2 billion.

As a technology company independent of any media business, AppNexus is uniquely positioned to offer both buyers and sellers solutions to achieve their online advertising goals. The company will now work to align the AppNexus and OAS™ technology stacks to create the most innovative offering in the industry to respective clients and the industry at large.

This deal also strengthens the position of Xaxis as the global leader in programmatic audience products, including those such as Xaxis TV and Xaxis Prime, which enhance the digital media experience for consumers and deliver higher ROI for advertisers. The divestiture allows Xaxis to focus software development on its own robust platform including its Turbine DMP, analytics suite, and cross-channel optimization technology, all while continuing to have direct access to high-quality publishers.

“Our clients want world-class solutions from independent ad technology companies,” said Sir Martin Sorrell, CEO of WPP. “We’re delighted to deepen our partnership with AppNexus, which has proven itself as a clear leader in ad tech and a company with the scale and ingenuity to continue to transform our industry.”

Publishers want a technology partner they can trust,” said Brian O’Kelley, CEO of AppNexus. “Open AdStream has been one of the most effective and trusted ad serving platforms in the world for years. We’re going to make it #1 in programmatic.”

“Xaxis is committed to building and partnering to provide world-class ad technology and solutions for our clients,” said Brian Lesser, CEO of Xaxis. “This allows both companies to double down on what we do best. We’re focusing our technology development on data management, decisioning, and new products. Open AdStream is in great hands as a part of AppNexus’ powerful independent tech stack.”

The transaction is subject to regulatory approval and customary closing conditions, and is expected to close by year end.
