S4 Capital, posting an improved profit margin via cost cutting to catch up with shrinking revenue, has rewarded shareholders with their first dividend.
Martin Sorrell’s pure-play digital advertising group reported revenue down 4.7% like-for-like to £308 million in the half year to June, with clients cautious in an uncertain world and the big digital players -- S4's target clients -- throwing money at AI development.
However, S4 improved profitability, with its operational EBITDA (earnings before interest, taxes, depreciation, and amortisation) margin at 12.3%, up 600 basis points or 710 like-for-like, on the back of tight cost controls.
Headcount was down 10.5% to 6,150 compared to the same time last year and 3% compared to December 2025.
The company announced an inaugural interim dividend of 1.35 pence per share, representing 50% of the adjusted basic earnings per share of 2.7 pence.
S4 said full year like-for-like net revenue is now estimated to be down in the mid-single digits, a deterioration from its previous guidance of "slightly below" 2025.
The company expects clients to remain cautious in the near term, reflecting heightened macroeconomic uncertainty as a result of the conflict in the Middle East.
“Throughout the first half of 2026, our trading reflected the continuing impact of increasingly volatile global macroeconomic conditions, heightened by increasing geopolitical risks,” Sir Martin said.
“Clients remained cautious amid this uncertainty, with technology clients/ hyperscalers continuing to prioritise and, indeed increase, capital expenditure on expanding AI capacity over operating expenditure.
“The four biggest hyperscalers alone are currently projected to spend over $5 trillion on AI related capital expenditure between 2025-2030.
“Despite the challenging backdrop and usual, although reducing, seasonal weighting to the second half, liquidity improved significantly compared to the first half of 2025, driven by disciplined cost control and strong working capital management, resulting in a reduction in net debt.
“The record operational EBITDA in the first half was primarily due to the impact of cost actions taken in the second half of 2025 and continued disciplined cost management.
“We have lowered our net debt in the first half due to our focus on working capital and liquidity, and therefore, now target a lower year end net debt range of £50 - £80 million.”
Sir Martin sees growing opportunities as clients become more selective about growth geographically and increasingly focused on implementing technologies such as AI, Blockchain and Quantum to drive efficiency.
“Whilst transformational change of the marketing function has been restricted so far to verticals where there are existential threats, like Automotive, Financial services and FMCG, there are signs that this revolutionary change will spread to other verticals, particularly (ironically) if growth rates slow in the coming months,” he said.
“One other observation – there is a lot of chatter in the industry about ‘trust’. You can’t have trust without transparency.
“The industry media model will be moving to a ‘transparently transparent’ model from a ‘transparently untransparent’ model (to quote Irwin Gotlieb), given all the competitive conflict around the rights and wrongs of propriety trading and take rates.”
