Publicis reports 5% organic growth in Q3 2026

Publicis posted 5% organic net revenue growth and won PepsiCo's global media account, setting the first benchmark of holding-group reporting season.

Publicis Groupe reported organic net revenue growth of 5% in the third quarter of 2026, an acceleration on the prior quarter, according to Quartz and AdExchanger. The group also won PepsiCo's global media account from Omnicom and topped new-business rankings over the period, per the same reports. Publicis is the first of the large holding groups to report this quarter, so the figures become the reference point against which rivals' Q3 numbers are read. The reporting lands while the Omnicom-Interpublic combination absorbs much of the sector's attention.

Havas net revenue up 7.2%, mostly from acquisitions

Havas reports 7.2% net revenue growth in Q3 2026, of which 3.2 points came from acquisitions and 2.4 points from organic work — a read on how much sector growth is being bought.

Full story

The company described the organic figure as resilient and singled out the United States, where it reported 7.5% growth. Havas characterised the acquisition contribution as reflecting an active strategy of bolt-on and targeted deals. Adweek also covered the results.

Prebid proposes reversing auction flow with Google's ad server

Prebid is drafting the mechanics of Google's court-ordered integration itself, proposing that ad servers bid into Prebid rather than the reverse — a change publishers and vendors would have to rebuild around.

Full story

A federal court last month ordered Google to integrate with Prebid but did not specify how, AdExchanger reports. Prebid is now advancing its own proposal, under which ad servers would bid into Prebid rather than Prebid bidding into the ad server. AdExchanger characterises the effect as separating AdX from Google Ad Manager in practice — something the ruling itself did not order. Google has not publicly responded to the proposal, so whether the reversed flow is adopted remains unresolved.

Welcome in, today is Thursday, October fifteenth, and we begin with Publicis, where Quartz reports third-quarter organic growth of five percent. Publicis Groupe posted organic net revenue growth of five percent in the third quarter, accelerating from four point eight percent in the prior quarter, per Quartz. That reporting puts net revenue at three point eight one billion euros, about four point four billion dollars, against an analyst consensus pegged at four point eight percent. Connected Media, sixty-two percent of net revenue, grew high single digits. Intelligent Creativity, twenty-five percent, grew low single digits. The technology practice, the remaining thirteen percent, declined low single digits globally, though its United States operations returned to growth. With the big holding groups reporting, that five percent becomes the benchmark rivals get measured against while the completed Omnicom and Interpublic merger absorbs attention. Chief Executive Arthur Sadoun credited demand for AI-powered products and services. The same account has Publicis winning PepsiCo's global media account from Omnicom last month, with analysts expecting no revenue contribution until next year. Full-year guidance is confirmed at four point five to five percent organic. AdExchanger reports industry reaction leans skeptical of the pitch-free framing, with a recurring concern, not a confirmed finding, that aggressive commercial terms are doing part of the work. Also today, Havas. Third-quarter net revenue rose seven point two percent year over year, to seven hundred and three million euros, roughly seven hundred eighty-two million dollars. Organic growth was two point four percent, down from three point eight percent a year earlier, with acquisitions adding three point two percent and currency one point six percent, according to the company's results statement. That split is the read on how much sector growth is being bought rather than won. North America was the strongest region at seven point five percent organic, which Adweek reports chief financial officer François Laroze attributed to the creative side, specifically Uncommon Creative Studio. Asia Pacific and Africa, where Havas groups the Middle East, fell six point seven percent. Latin America fell four point three percent, and the same reporting has Havas losing Telefonica there. Laroze said Havas has made eight acquisitions this year and is on track for ten, and is in review for two global clients through its media venture with Horizon Media. Full-year organic guidance holds at two to three percent. On the adtech side, a development in the Google ad tech case, following our earlier report on the proposed final judgments filed by Google and the Justice Department. AdExchanger reports that Prebid is now writing the integration instructions the court did not. In headline form, that account says the organization is moving ahead with a proposal to let ad servers bid into Prebid, reversing the current flow, in which Prebid bids into ad servers. Publishers and their vendors would be rebuilding auction plumbing around it. Google has not publicly responded. Separately, WPP has named Adam Gerhart Global Chief Client Officer, putting the group's biggest client relationships in one set of hands as its restructuring continues. Per Mediaweek, he will lead those key global relationships and oversee the network of Global Client Leaders, based in New York, joining the Executive Committee and reporting to Chief Operating Officer Devika Bulchandani. The same reporting has him tasked with expanding partnerships across WPP's integrated offerings and driving cross-agency collaboration using data, AI and creativity. Gerhart most recently served as Global Chief Client Officer of WPP Media, and earlier held that title at GroupM and was Global CEO of Mindshare. MediaPost describes him as a twenty-three year WPP veteran, largely on the media side. Bulchandani said there is simply no one better than Adam to represent the best of WPP to our clients. The appointment follows WPP ranking first in net new business for the second quarter and first half of twenty twenty-six, according to J.P. Morgan estimates. Now, a few more headlines moving the trade today. Publicis chief executive Arthur Sadoun told the earnings call that the holding groups are now big enough to manage client conflict, and that global pitches are effectively a three-way contest, Mumbrella reports. On the platforms side, Bloomberg first reported that Meta has blocked ByteDance ads, and third-party campaigns pointing to TikTok, across seven markets including the United States. And finally, Adweek has published the shortlist for its twenty twenty-six Experiential Awards, with winners due in the December eighth issue.
