Publicis Groupe’s shares briefly jumped 5% on speculation that Vivendi, the owner of Havas, could push for a tie-up or takeover.
A report in French business title Challengers said Vincent Bolloré, the mogul behind Vivendi, could have as much as $7.6bn to invest by the start of 2024 and is unlikely to “enter a business [sector] that he does not already know ... hence he may be looking at Publicis again”.
However, analysts at Bank of America said the prospect of an M&A deal between the two French groups was “unlikely”, saying the “planets don’t seem aligned”.
Publicis' stock price leapt from about $77 to $82 at 10am on Thursday (6 July) but fell back during the day and closed down nearly 2% at $76 amid wider market fears about rising interest rates.

Spokespeople for Vivendi and Publicis said they had no comment when approached by Campaign.
Bank of America said in a note to investors: “While this is not the first time that a tie-up between Publicis and Vivendi is speculated, we have no reason to believe that today’s article has any more basis than the previous press reports.”
The investment bank’s analysts cited a series of potential obstacles, including the Badinter family, which has about 10% of the voting rights in Publicis, and the stock market valuations of the two companies. Publicis is worth about $19.7bn — twice the value of Vivendi – although the family-controlled Bolloré Groupe has other assets.
A tie-up between Publicis, which employs close to 100,000 people, and Havas, which has upwards of 20,000, “could create some cost synergies but also lead to integration issues”, the analysts added, recalling how Publicis and Omnicom abandoned their planned merger in 2014.
Bank of America noted Bolloré had previously “shown an appetite for lowly rated under-performing assets where he can wield influence without acquiring full ownership”, including buying a stake in Aegis Group, before its subsequent sale to Dentsu in 2012. But Publicis, under the leadership of Arthur Sadoun, the chief executive, has been “largely outperforming its peers” since the pandemic.
There has been on-off industry chatter that Vivendi, the owner of media assets including Canal+ and Editis, has been eyeing Publicis, the world’s second biggest ad agency group by staff headcount behind WPP.
