Martin Sorrell-led S4 Capital won’t be detailing its full 2025 results until late March, but it has issued a brief update in which it disclosed that its net organic revenue decline for last year will be down about 8.5%. 

That’s more precise that the previous guidance issued in November when the company advised that the decline would be below 10%. 

Full-year net revenue will be more than the current analyst consensus of 664 million GBP (about $907 billion), the company said.  

By comparison, the firm reported a full-year 2024 net revenue decline of 13.6% to 754.6 million GBP (about $977 million) with an organic revenue shortfall of 11%.
