S4 Capital’s full-year 2025 performance came in ahead of revised guidance and above market expectations, with results set to be published in March. 

The digital advertising and marketing group expects like-for-like net revenue to fall by around 8.5%, while delivering an operational EBITDA margin of about 12%, ahead of consensus forecasts of £664 million net revenue and £75m EBITDA. 

It also reported a sharp improvement in liquidity, with net debt expected to be below both the £133m consensus and its previously guided range of £100m-£140m, helped by tighter treasury and working capital management. 

Executive chair Sir Martin Sorrell said there is still more work to do on growth and margins in 2026, but confirmed the board intends to recommend a 1p dividend.

The London-based MarTech’s shares have risen by nearly 40% to 26.5p in the first two hours of trading today.
