All marcom stocks rise in broad sector rally

From Omnicom's Adidas Win to Dentsu's Meta Deal: The News Behind the Share Prices

Listed marketing and communications companies posted broad share price gains this week. All six companies tracked by Marketing Report are trading higher than a week ago, with several recording double-digit increases.

The biggest gains came from S4 Capital and WPP, up 14.3% and 13.6% respectively—two companies that have faced pressure over recent quarters. Omnicom also recorded a strong rise on company-specific news. The overall picture points to renewed investor interest in the sector, although one week is too short a period to draw firm conclusions, and part of the gains reflect a rebound from previously depressed valuations.

WPP rises despite account loss

WPP gained 13.6%, rising from 235.8 pence to 267.8 pence. The increase came despite the recent loss of a major global media account. On the positive side, WPP Media retained L'Oréal's media account in Australia and New Zealand following a competitive review against Publicis and Omnicom. Trade publications described the outcome as a return of WPP Media to the top tier of the regional market. Trading volumes in the stock were relatively light, with investor attention focused primarily on the company's underlying performance.

Publicis edges higher as LiveRamp acquisition raises questions

Publicis rose 1.9%, from €86.46 to €88.14, making it the weakest performer among the group. In the background is its $2.2 billion acquisition of data platform LiveRamp, announced in May. Competitors have openly questioned whether LiveRamp can remain neutral under Publicis ownership, with Omnicom CEO John Wren among those considering moving away from the platform. This week, LiveRamp launched a brand campaign on Netflix highlighting its neutrality and reliability.

S4 Capital rebounds after weak quarterly results

S4 Capital was the week's strongest performer, gaining 14.3% from 31.5 pence to 36 pence. The rebound follows a period of pressure after the company reported declining first-quarter revenue, which had weighed on the share price. The move highlights the volatility of the relatively small-cap company, whose shares tend to react more sharply than larger peers during sector-wide revaluations.

Dentsu signs Meta data partnership for creator activation

Dentsu gained 8.4%, rising from 3,097 yen to 3,358 yen. Through an API integration, the agency has connected Meta's Creator Marketplace and Partnership Ads with its proprietary Dentsu.connect platform, bringing social listening, creator selection, and paid activation into a single environment. Dentsu says the integration will enable creator campaigns to be executed more quickly and at greater scale, with the United States identified as the next market for rollout. The initiative forms part of the rebuilding of its international operations after the sale process for that business collapsed earlier this year.

Omnicom wins Adidas and strengthens data capabilities

Omnicom gained 11.0%, rising from $72.83 to $80.84. Effective July 1, the company took over Adidas' global media account, valued at approximately $512 million, to be managed by PHD. Omnicom also introduced a new sports data platform called Fan Graph through its subsidiary Acxiom. The share price increase coincides with the ongoing integration of IPG, which will make Omnicom the world's largest advertising company by revenue.

Havas wins Spin Master and settles with the FTC

Havas rose 6.7%, from €17.05 to €18.20. Havas Media was appointed media agency for toy and entertainment company Spin Master following a competitive pitch, adding brands such as PAW Patrol and Gabby's Dollhouse to its portfolio. Havas also became the last of the former Big Six agency groups to reach a settlement with the U.S. Federal Trade Commission (FTC) in the brand safety case, in which agencies were accused of unlawfully coordinating advertising placement standards. The company also announced progress on its share buyback programme and created a new Chief Strategy Officer role, filled by De Andreis.

Analysis

The week's gains were broad-based across all tracked companies, although the drivers differed. WPP and S4 Capital rebounded from previously depressed levels, while Omnicom and Dentsu benefited from developments in data and creator infrastructure. Havas combined new business wins with the resolution of a legal matter. Publicis recorded the smallest gain amid ongoing questions about LiveRamp's neutrality.

The common theme is that investors are rewarding companies demonstrating tangible progress in data, AI, and creator capabilities—the same strengths increasingly driving major account wins. However, one week's performance does not establish a long-term trend, and part of the gains reflects recovery from earlier declines rather than a fresh wave of investor optimism.
