Nielsen has agreed to acquire digital ad verification company, DoubleVerify, in an all-cash transaction with an enterprise value of approximately $2 billion.
Under the terms of the agreement, DoubleVerify shareholders will receive $14 per share in cash, representing a 30 per cent premium to the company’s 60-trading day volume weighted average price.
The deal brings together Nielsen’s audience measurement and media analytics business with DoubleVerify’s ad verification and media quality platform, creating a combined entity that is expected to generate more than $4 billion in revenue on a pro-forma basis.
Upon completion, DoubleVerify will become a privately held company as part of Nielsen. Its common stock will no longer be listed on any public market, though the company will continue to operate under its own name and brand.
Building an end-to-end platform
The Chief Executive Officer of Nielsen, Karthik Rao, framed the acquisition as an extension of the company’s broader transformation.
“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,” Rao stated.
“The result is a stronger, more agile Nielsen that has earned its place as a media intelligence platform for the modern advertising ecosystem.”
Rao pointed to the potential for the combined company to offer publishers, advertisers, agencies and platforms an independent partner that connects audience intelligence with verified media delivery.
“Joining forces with DoubleVerify will extend our capabilities deeper into the digital media industry, ensuring that the spend flowing between buyers and sellers is reaching real people in brand-suitable environments, through verified channels,” he explained.
“As advertising workflows become increasingly automated, together we can offer publishers, advertisers, agencies and platforms a truly independent, end-to-end partner that connects trusted audience intelligence with verified media delivery – across every screen, every channel and every transaction.”
DoubleVerify sees opportunity in going private
The Chief Executive Officer of DoubleVerify, Mark Zagorski, described the deal as an opportunity to accelerate growth under Nielsen’s ownership.
“As a private entity with the support of Nielsen, we will have access to expanded resources to deliver new, market-relevant solutions that drive value for our customers and partners,” Zagorski commented.
He highlighted the potential for combining DoubleVerify’s MRC-accredited quality signals with Nielsen’s cross-screen audience measurement capabilities.
“DoubleVerify’s MRC-accredited quality signals, in combination with Nielsen’s deduplicated cross-screen audience measurement, will fuel genuine market innovation – a single currency that scores media on both audience delivery and media environment quality,” Zagorski added.
What the deal covers
Nielsen’s platform currently spans the media lifecycle from content discovery and audience planning through to cross-platform measurement and outcome attribution.

DoubleVerify adds an independent verification layer designed to confirm that the impressions behind advertising campaigns are real, viewable, brand-suitable and free from invalid traffic.
The combined company’s operations are expected to touch more than $300 billion in advertising spend, expanding Nielsen’s reach into the $240 billion digital advertising segment through DoubleVerify’s existing integrations with platforms, publishers and agency groups.
Nielsen products currently serve media decisions across television, streaming, audio and sports. The acquisition would extend that reach across linear TV, connected TV, social, mobile and AI platforms.
Preserving independence and verification standards
A central theme of the deal’s rationale is maintaining independent verification standards for the advertising industry.
The combined company has committed to continuing DoubleVerify’s existing capabilities in invalid traffic detection, viewability and brand suitability, which Nielsen has characterised as industry standards that global advertisers depend on.
The Chairperson of the Board of DoubleVerify, R. Davis Noell, pointed to the company’s track record in digital media quality.
“DoubleVerify has established itself as a benchmark in digital media quality and effectiveness,” Noell remarked. “Over its growth trajectory, DoubleVerify expanded its AI-powered platform, deepened customer relationships and scaled into a category operator.”
“Bringing these assets together creates a win for both companies’ customers and partners. We’re excited for Mark and the DoubleVerify leadership team as they continue that journey with Nielsen.”
AI and the ad fraud arms race
The deal also positions the combined company to address the growing role of AI in advertising workflows.
DoubleVerify has been investing in AI-driven fraud detection capabilities, using proprietary data and human expertise to combat what the company has described as surges in ad fraud driven by agentic AI.
As AI-driven planning, activation and optimisation reshape how campaigns are built and executed, the combined entity is expected to provide the verified data, outcome signals and platform integrations needed to support increasingly automated advertising processes.
Deal structure and financing
The transaction has been approved by the boards of directors of both companies and is expected to close by the first quarter of 2027, subject to approval by DoubleVerify shareholders, regulatory approvals and other customary closing conditions.
Financing will come through a combination of committed debt financing provided by Barclays, BofA Securities and Citi, along with incremental equity financing and cash on hand at Nielsen.
Funds affiliated with Providence Equity Partners, which own approximately 11.8 per cent of DoubleVerify’s outstanding shares of common stock, have agreed to vote their shares in favour of the transaction. Providence will conclude its investment upon close.
