Publicis bought Epsilon to win the personalization era. It is buying LiveRamp to win the agentic one.
Publicis Groupe has agreed to acquire LiveRamp, the global data collaboration platform, for a total enterprise value of $2.167 billion in an all-cash transaction — its most significant strategic bet since the $4.4 billion acquisition of Epsilon in 2019 and a clear signal of where the world’s third-largest advertising group believes the next competitive frontier lies.
The deal, priced at $38.50 per share and representing a 29.8 percent premium to LiveRamp’s closing price on May 15, has been unanimously approved by the boards of both companies. It is expected to close before the end of 2026, subject to regulatory approval and LiveRamp shareholder sign-off.
What LiveRamp Is
LiveRamp is not a conventional advertising technology company. It is infrastructure — a data collaboration platform that enables organizations to unify, manage, and activate data across the digital ecosystem without exposing the underlying sensitive information that makes that data valuable.
Its network spans more than 25,000 publisher domains and over 500 technology and data partners across 14 markets. Thousands of brands, retailers, media platforms, and data providers use its clean room technology to collaborate on data they could not share through conventional means. With 1,300 employees and a business anchored in highly recurring revenue, LiveRamp has delivered a compound annual revenue growth rate of 13 percent over the past five years.
Why Publicis Is Buying It
The acquisition is a direct response to what Publicis identifies as the defining constraint on enterprise AI adoption: most companies lack the right data to make their AI systems genuinely effective. According to figures cited by Publicis, 93 percent of companies do not currently have the data infrastructure required for AI success.
LiveRamp addresses that gap through what Publicis calls data co-creation — the process by which companies combine multiple high-value data sources across partners in secure, governed environments to generate new proprietary data assets that no single organization could build alone.
Combined with Epsilon’s identity resolution capabilities, LiveRamp’s collaborative infrastructure is designed to enable clients to build AI agents that are more capable, more differentiated, and more commercially effective than anything a single organization’s data could support independently.
“After acquiring Epsilon in the name of personalization at scale and enabling our clients to take back control of their data from the walled gardens,” said Arthur Sadoun, Chairman and Chief Executive of Publicis Groupe, “once again we are looking ahead to what’s next. By building the future of data co-creation, we’re empowering our clients to generate new, exclusive and proprietary data — to build the smartest, most differentiated AI agents on top of the leading large language models.”

The Use Cases
Publicis has been explicit about what data co-creation enables in practice, offering three illustrative examples.
A bank could build a wealth management agent that draws on tokenized customer data from retail banking, credit cards, and wealth management, combined with partner data from merchants, payment networks, and travel providers — without exposing underlying customer records. The result is an agent capable of cross-selling across multiple business lines with far greater precision than any single dataset would allow.
A retailer could connect loyalty, in-store, and retail media data with partner signals to measure the incremental value of each customer touchpoint and build new, proprietary shopper journeys — turning retail media from a cost center into a measurable growth driver.
A pharmaceutical company could build a therapeutic area optimization agent that draws on clinical, commercial, supply chain, and de-identified patient data simultaneously — enabling more efficient field-force deployment and better product lifecycle management across an entire portfolio.
The Strategic Architecture
The LiveRamp acquisition completes what Publicis describes as an end-to-end capability stack for agentic business transformation. Publicis Sapient provides the technology modernization layer that makes enterprise infrastructure AI-ready. Epsilon’s identity resolution connects agents to real people, behaviors, and deterministic transactions. LiveRamp enables secure data collaboration across partners to generate the co-created data that fuels smarter agents. Marcel, Publicis’s internal agentic platform, activates that data across enterprise functions.
Each component addresses a different layer of the same problem. Together, Publicis is arguing, they constitute a capability set that no competitor can currently match end to end.
Financial Implications
The transaction is expected to be earnings-accretive from the first year of consolidation, excluding transaction-related costs. Publicis is funding the acquisition with cash on hand and debt, maintaining financial leverage within existing investment-grade rating parameters, with full deleveraging expected within two years of closing.
The deal also allows Publicis to raise its medium-term financial guidance. The Groupe now targets net revenue growth of 7 to 8 percent and headline earnings per share growth of 8 to 10 percent at constant currency in 2027 and 2028 — up from prior targets of 6 to 7 percent and 7 to 9 percent respectively.

What Changes — and What Does Not
LiveRamp will continue to operate as a neutral, interoperable platform following the acquisition. Chief Executive Scott Howe will remain in his role, reporting directly to Sadoun. The company’s data will continue to be protected in accordance with existing contractual commitments. Pricing and commercial practices will remain unchanged outside the normal course of business.
The commitment to neutrality is not incidental. LiveRamp’s value depends on the trust of the 500-plus technology and data partners and 25,000-plus publishers in its network — a trust that would erode quickly if the platform were perceived to operate in the exclusive interest of its new parent company.
“Our customers and partners have always been our North Star,” said Howe. “By joining forces with Publicis, we will have greater resources and flexibility to scale our business, continue innovating our platform, and help them unlock even greater value from their data.”
The transaction is expected to close before year-end 2026.
