Nielsen buys DoubleVerify for $2.15 billion in all-cash deal
The all-cash acquisition values DoubleVerify at approximately $2.15 billion, or $13.60 per share, a 30% premium over its recent trading price, and comes as advertisers and media companies press for a single system to measure viewership across linear TV, streaming and digital platforms. Both companies' boards have approved the transaction, which needs sign-off from DoubleVerify shareholders and regulators before it can close, a process the companies expect to complete by the first quarter of 2027. Providence Equity Partners, which owned about 11.8% of DoubleVerify's shares as of August 5, 2026, has committed to vote in favor and will sell its stake when the deal closes. DoubleVerify CEO Mark Zagorski said the deal gives the company "access to expanded resources to deliver new, market-leading solutions." Nielsen has faced growing competition in TV measurement, including from iSpot, which last week expanded its data partnership with Fox to track how commercials drive outcomes like showroom visits.
Campaigns planned across linear and streaming currently rely on separate vendors to check that impressions were real and that ad spend reached brand-safe environments, a split Nielsen wants to close by combining its audience panels with DoubleVerify's verification tools. Buyers evaluating cross-platform deals could eventually see a single Nielsen-DoubleVerify currency that scores both reach and media quality, cutting the reconciliation work agencies now do across measurement providers. The deal also signals consolidation pressure on rivals like iSpot and Comscore as the industry moves toward unified metrics that cover every screen a viewer uses.
