Publicis Groupe said it will acquire U.S. data specialist LiveRamp in a deal valued at $2.2 billion [2].

The acquisition marks a significant consolidation in the advertising technology sector, as a major global agency integrates specialized data capabilities to better target consumers.

Shares of LiveRamp surged about 27% [1] on Monday following the announcement. The stock, which trades on the Nasdaq, saw a rapid increase as investors reacted to the acquisition price offered by the French advertising company.

Publicis Groupe is moving to strengthen its data infrastructure by bringing LiveRamp's identity resolution and data connectivity tools in-house. The $2.2 billion [2] price tag reflects the growing value of first-party data in an era where traditional third-party cookies are being phased out across the web.

LiveRamp has established itself as a critical link for brands seeking to connect their offline and online customer data. By acquiring the company, Publicis aims to provide its clients with more precise targeting and measurement tools, a move intended to compete with other large-scale data ecosystems.

Market analysts said that the 27% [1] spike in share price indicates investor confidence in the valuation and the strategic fit between the two companies. The deal is expected to streamline how Publicis manages complex data sets for its global advertising portfolio.

This acquisition signals a shift in the advertising industry toward 'walled gardens' of data. By owning the data-specialist tools used for identity resolution, Publicis reduces its reliance on external vendors and gains a proprietary advantage in targeting. It suggests that the ability to track users without third-party cookies is now a primary driver of corporate valuation in the ad-tech space.
