S4 Capital cuts jobs as Sorrell predicts ‘fewer people’ in advertising
S4 Capital has cut a further 150 jobs this year, amid warnings from Sir Martin Sorrell that AI will leave the advertising industry employing “fewer people” in the years ahead.
The London-listed marketing group said its workforce has fallen to around 6,200, down from roughly 7,000 a year ago, as clients continue to rein in spending amid geopolitical tensions and economic uncertainty.
These latest reductions come as S4, which owns digital marketing network Monks, battles a prolonged slowdown among many of its largest tech clients.
The company expects revenue to fall again this year, forecasting a low single-digit decline to between £632m and £663m.
The advertising veteran told CityAM it would be “disingenuous for anybody to suggest otherwise” when asked whether AI would lead to job displacement across the sector.
“There are going to be fewer art directors and copywriters,” he said. “There’ll be fewer people in media planning and buying. Net-net, to answer your question head-on, there will be less.”
S4’s Thursday trading update, while warning that market conditions had become “more challenging”, also pointed to “growing opportunities” as clients increasingly adopt AI tools to improve efficiency.
“AI consumers are adopting AI faster than companies,” he told CityAM. “If it ain’t broke, don’t fix it. Companies are very hesitant to change when they’re doing well.”
Clients tighten budgets as AI spending rises
The challenge for the media empire is that many of the companies best placed to spend heavily on marketing are instead directing vast sums towards AI infrastructure.
Nearly half of the group’s revenue comes from technology clients including Amazon, Google and Meta.
While those firms continue to invest aggressively, much of that spending is flowing into data centres, chips and computing power rather than advertising budgets.
“We’d like to see clients spending a bit more on marketing,” Sorrell said.
That imbalance has weighed heavily on S4’s top line, with revenue falling sharply last year and the group having spent much of the past 18 months reducing costs and cutting headcount in a bid to protect margins.
The company said on Thursday that trading had remained in line with expectations despite a backdrop dominated by war in the Middle East, tariff uncertainty and stubborn inflation.
“Clients generally [remain] cautious,” S4 said.
Sorrell has repeatedly argued that corporate caution has become the defining feature of the current market.
“Companies are doing very, very well,” he told CityAM. “The puzzle is why they’re not spending more. I think it’s because they’re squeezing their supply chain.”
That squeeze is being felt across the ad sector, where agencies are grappling with flat revenues and growing questions over how many jobs AI will ultimately replace.
Sorrell, however, insists the technology is as much opportunity as threat, but that the bigger risk is failing to adapt.
“It’s an opportunity for disruptors,” he said. “The traditional companies are under huge pressure.”
