What Leadership Is Saying?
Sir Martin Sorrell, Executive Chairman:
“Throughout 2025, our trading reflected the continuing impact of increasingly volatile global macroeconomic conditions, heightened by tariff negotiations and increasing geopolitical risks. Clients remained cautious amid this uncertainty, with technology clients representing almost half our revenue continuing to prioritise capital expenditure on expanding AI capacity over operating expenditure.
Despite the challenging backdrop and usual seasonal weighting to the second half, liquidity and cashflow improved significantly year-on-year, driven by disciplined cost control and strong working capital management, resulting in a substantial reduction in net debt over the course of the year. We remain confident in our strategy, business model and talent. Together with our scaled client relationships and the strong momentum behind our new go-to-market propositions, we believe we are well positioned to deliver sustainable long-term growth.”
Radhika Radhakrishnan, Group Chief Financial Officer:
“Despite global macroeconomic pressures and ongoing client caution, strong cost and working capital management improved the operational EBITDA margin and reduced year-end net debt below the targeted range. Net revenue was GBP 673 million, down 10.8% reported and 8.4% like-for-like. Operational EBITDA was GBP 81.2 million with a margin of 12.1%, up 70 basis points year-on-year.”

Competitor Comparison: FY 2025 vs FY 2024
The advertising and marketing services sector experienced a broadly divergent set of outcomes in full year 2025, with Publicis outperforming while WPP faced deeper structural challenges alongside S4 Capital.
| Company | FY 2025 Revenue | FY 2024 Revenue | Revenue Change | Operating Margin | Notable |
| S4 Capital (LSE: SFOR) | £673.0m (net rev) | £754.6m (net rev) | -10.8% reported | 12.1% Op. EBITDA margin | Free cash flow doubled; stock +25% on results |
| WPP (LSE: WPP) | £13,550m | £14,741m | -8.10% | 13.0% headline | Goodwill impairments of £641m; net loss of £215m |
| Publicis Groupe (EPA: PUB) | EUR 14,547m (net rev) | EUR 13,965m (net rev) | +4.2% reported (+5.6% organic) | 18.2% | Outperformed all major peers; AI-driven growth |
| Omnicom (NYSE: OMC) | USD 17.3 billion | USD 15.7 billion | +10.1% (includes IPG acquisition) | 15.6% adj. EBITA margin | IPG acquisition closed Nov 2025; organic growth more modest |
The agency sector was sharply bifurcated in 2025. Publicis benefited from strong AI integration and major new business wins including Coca-Cola, Mars and PayPal accounts taken from WPP. WPP struggled with excessive organisational complexity and continued client losses, with headline operating margin declining from 15% to 13%.
Omnicom’s headline revenue growth largely reflects the late-2025 close of the Interpublic Group acquisition rather than organic momentum. S4 Capital’s revenue decline was deeper than WPP’s on a like-for-like basis but the company differentiated itself on balance sheet improvement, cash conversion and margin expansion.
How the Market Reacted?
S4 Capital shares surged approximately 24.94% to 20.45 pence on 24 March 2026, the day audited results were published, as investors responded positively to the combination of margin expansion, sharply improved free cash flow and a net debt outcome below the company’s own targeted range. The stock had been under intense pressure throughout 2025 after S4 Capital issued its revenue guidance downward four separate times during the year.
The proposed 10% increase in the final dividend to 1.1p per share added to the bullish tone, signalling board confidence in continued progress, and shares have since traded in the 25-26 pence range. The market’s reaction was one of relief rather than celebration, as the company still reported a statutory net loss of £24.8 million and guided for a further modest decline in full year 2026 like-for-like net revenue, though with an operational EBITDA margin improvement of at least 100 basis points expected.
