LONDON—British advertising group M&C Saatchi has agreed a takeover by consultancy Next Fifteen Communications, which it said on Friday represented a better offer than one made by its biggest shareholder.
M&C, founded in 1995 by brothers Maurice and Charles Saatchi, has been recovering from a 2019 accounting scandal but last month reported a record annual profit helped by client wins and deepened relationships with the likes of Alphabet’s Google, Uber, and TikTok.
