("S⁴Capital" or "the Company")

Update regarding Executive Chair

The Company provides below an internal note that Sir Martin Sorrell will share today:

"To all S4.Monks:

I wanted to update you following the successful keyhole surgery I had in February, which was to remove a tumour. I have made an excellent recovery, and, as you would expect, I have sought the best possible medical advice. My conclusion is that I should have preventative treatment over the coming months. My doctors have advised me that during this treatment, I should be able to work as normal most of the time, fully engaging with the Company and our excellent Executive team, although I have also decided to reduce my travel schedule for a few weeks. Otherwise, business as usual. Thank you as ever for your continued support and let me know how to help you in any way I can.

Sir Martin Sorrell"
