Nielsen is betting on independent verification, agreeing to acquire ad-quality firm DoubleVerify in an all-cash deal that pulls the ratings firm deeper into digital advertising as part of a deal it calls an extension of changes already underway at the company.
Nielsen said the combination pairs its cross-platform audience data with DoubleVerify’s media-quality verification, giving advertisers a single source to confirm that ad spend is reaching real, brand-suitable audiences.
Both companies’ boards have approved the deal, which is expected to close by the first quarter of 2027, subject to shareholder approval and regulatory clearance.
Under the agreement, DoubleVerify shareholders will receive $13.60 per share in cash, a 30% premium to the company’s 60-trading-day volume-weighted average price as of August 5. The deal values DoubleVerify at an enterprise value of approximately $2.15 billion. Nielsen projects the combined company will generate more than $4 billion in revenue, with access to a $300 billion-plus advertising market as digital budgets continue to grow.
Nielsen CEO Karthik Rao said, “Over the last few years, Nielsen has undergone a fundamental transformation — accelerating product innovation; expanding our platform across the full media lifecycle, from discovery and planning through measurement and outcomes; and strengthening our financial foundation. The result is a stronger, more agile Nielsen that has earned its place as a leading media intelligence platform for the modern advertising ecosystem.”
DoubleVerify CEO Mark Zagorski commented, “Today’s announcement is an exciting milestone for DoubleVerify. As a private entity with the support of Nielsen, we will have access to expanded resources to deliver new, market-leading solutions that drive exceptional value for our customers and partners.”
DoubleVerify Board Chair R. Davis Noell remarked, “DoubleVerify has established itself as the global benchmark in digital media quality and effectiveness. Over its growth trajectory, DoubleVerify expanded its AI-powered platform, deepened customer relationships, and scaled into a true category leader. Bringing these assets together creates a significant win for both companies’ customers and partners.”
