regain their own margins. We suspect that objectivity/neutrality is among the largest

sources of pushback from advertisers as agencies vertically integrate the ad tech

supply chain. Notably, the LiveRamp acquisition will raise further questions about TTD's

relationship with Publicis amidan ongoing dispute over TTD's fees.

Key Points

Publicis Groupe is Acquiring LiveRamp for $2.5B — The acquisition of LiveRamp

provides Publicis with high-value data sources that should help improve advertising

results for clients. Publicis believes that LiveRamp will make them a leader in data

co-creation, which they see as critical as agentic AI begins to shift the advertising

ecosystem.

It's Clear The Agency Model is Changing — The LiveRamp acquisition builds on

Publicis' prior acquisitions of Lotame and Epsilon, as agencies look to enhance their

value prop by bringing more ad tech capabilities directly in-house, allowing them to

recoup margin from 3P ad tech vendors. We highlight that this comes as agencies'

business models have been under pressure, forcing them to evolve to survive the

changing advertising landscape.
