L'Oréal Hands Its €350m DACH Media Account to Omnicom
Updated: 6 days ago
TL;DR: L'Oréal has awarded its roughly €350m DACH media business to Omnicom Media Group, ending Wavemaker's tenure — one of the biggest German media-account switches of the year, with the mandate starting January 2027.
One of the year's biggest German media reviews has concluded. L'Oréal has awarded its roughly €350m DACH media business to Omnicom Media Group, ending Wavemaker's tenure on the account.
The decision
The account was retendered in spring 2026, and Wavemaker — part of GroupM — failed to convince in the pitch. The new mandate starts in January 2027.
A win of this scale for Omnicom over a GroupM incumbent is a notable marker in the German media landscape, where big FMCG-and-beauty accounts rarely move.
Marketing Minute's read
Reviews of this size are decided on more than price. Increasingly, advertisers want a media partner that can prove measurement rigour, first-party data capability and AI-assisted planning — and a €350m beauty account is exactly where those capabilities are tested hardest.
For the market, the switch is also a confidence signal. When a blue-chip advertiser moves a flagship account, it tells smaller brands that incumbency is no longer a guarantee, and that reviews are worth running if your current setup has stopped delivering.
What marketers should take from it
Even if you're nowhere near €350m, the lesson travels: review your media arrangements on capability and measurement, not just loyalty or rate cards. The agencies winning the big accounts are the ones re-tooling around data and AI — ask whether yours is keeping pace.
Quick FAQ
Who won L'Oréal's DACH media account?
Omnicom Media Group, which takes over the roughly €350m DACH business from Wavemaker (GroupM), with the mandate starting January 2027.
Why do big media switches like this matter?
They signal that incumbency is no longer a guarantee, and that advertisers now decide large reviews on measurement, data capability and AI-assisted planning, not just price.
A €350m account doesn't move on price alone — it moves on data capability, measurement and AI-assisted planning, tested at the hardest end of the market. The signal for everyone else is simple: incumbency guarantees nothing. If your media setup has stopped delivering, a review is worth running. — Daniel Nikolla, Founder of Merx Marketing
