Shares in S4 Capital (LON:SFOR) slumped after the ‘digital-first’ media agency downgraded its FY26 like-for-like sales guidance. In a sobering update, the company warned the ‘challenging conditions’ witnessed in H1 continued into Q3.
For the quarter ended 30 September, like-for-like revenue fell 7.3% to £156.3 million. And executive chair Sir Martin Sorrell expects clients will ‘remain cautious’ in the near term.
FY26 sales downgrade
S4 Capital now expects FY26 like-for-like net revenue to be ‘marginally below’ previous guidance with a high-single digit decline. That represents a downgrade on the mid-single digit decline forecast back in August.
However, operational EBITDA margin is expected to increase by at least 160 basis points to 13.7%. And the company left its expectations for operational EBITDA unchanged at £85 million.
| £ millions | Q3 2026 | Q3 2025 | Like-for-like change |
| Revenue | 173.5 | 191.7 | (10.3%) |
| Marketing services | 142.7 | 150.8 | (6.2%) |
| Technology services | 13.6 | 16.2 | (17.6%) |

Moreover, S4 Capital expects year-end net debt to be ‘comfortably’ within the previously-guided £50 million to £80 million range.
What did Sorrell say?
‘Throughout the third quarter, our trading continued to reflect increasingly volatile global macroeconomic conditions, heightened by rising geopolitical risks,’ said Sorrell.
‘Clients remained cautious amid this uncertainty, with hyperscalers and other technology clients continuing to prioritise capital expenditure on expanding AI capacity over operating expenditure.’
Sorrell added: ‘We anticipate that clients will remain cautious in the near term reflecting this heightened macroeconomic uncertainty, including the continuing conflicts in Ukraine and the Middle East.’
After parting ways with WPP (LON:WPP), which he grew into a global media behemoth, Sorrell had a point to prove. Building S4 Capital has been tough, with the Covid pandemic, war in Ukraine and hostilities in the Middle East impacting client confidence.
Furthermore, ad spending globally has contracted. And budgets are now being diverted from marketing to investing in AI. To combat these headwinds, Sorrell has put his charge on a diet, cutting debt and overheads to protect margins.
These actions have helped S4 Capital’s shares to rally in 2026-to-date. Yet they have lost more than 90% of their value over the past five years. Given the uncertain backdrop, we maintain our view that the ad business and stocks like S4 Capital are best suited to investors with high risk tolerance.
