Merger negotiations between MSQ Partners and S4 Capital have been denied by MSQ Partners.
In a recent development, MSQ Partners, a U.K.-based marketing agency, has categorically denied any merger or acquisition talks with S4 Capital, according to the latest news reports in August 2025.
The denial comes after rumours of potential discussions between S4 Capital and MSQ Partners surfaced, with some speculating about a possible acquisition of MSQ by S4. However, MSQ responded with surprise at the merger reports, stating that no such deal is under consideration [1][2].
S4 Capital, founded by Martin Sorrell in May 2018, has a team of 9,000 people and is known for its focus on technology and digital advertising. The company, which has been linked with various merger and acquisition discussions in the past, had indicated that if a deal with MSQ were to occur, it would be structured as an acquisition of MSQ by S4.
This denial by MSQ Partners does not necessarily rule out future discussions, as there can be no certainty that a transaction will be forthcoming between the two U.K.-based companies.
Interestingly, S4 Capital's stock price received a boost in August, with shares jumping up to 14% in value, according to Reuters. This surge provided a market value of £140 million ($187.7 million) for the company. However, S4 Capital recently cut its 2025 revenue forecast to gains in the low single digits due to caution from its tech clients, who are affected by a weaker global economy and U.S. tariffs [3].
Martin Sorrell is best known for building WPP into a creative behemoth before founding S4 Capital. In 2023, U.S. marketing group Stagwell approached S4 Capital with a $700 million proposal, which was rebuffed by Sorrell [4].
