About S4Capital�

S4Capital plc (SFOR.L) is the new age/new era digital advertising and marketing services company, established by Sir Martin Sorrell in May 2018.

�

Its strategy is to build a purely digital advertising and marketing services business for global, multinational, regional, local clients and millennial-driven influencer brands. This will be achieved initially by integrating leading businesses in three practice areas: first-party data, digital content, digital media planning and buying, along with an emphasis on "faster, better, cheaper" executions in an always-on consumer-led environment, with a unitary structure.

�

Digital is by far the fastest-growing segment of the advertising market. S4Capital estimates that in 2018 digital accounted for approximately 45% or $225 billion of total global advertising spend of $500 billion (excluding about $400 billion of trade support, the primary target of the Amazon advertising platform), and projects that by 2022 this share will grow to approximately 55%.

�

S4Capital combined with MediaMonks, the leading AdAge A-listed creative digital content production company led by Victor Knaap and Wesley ter Haar, in July 2018, and with MightyHive, the market-leading programmatic solutions provider for future thinking marketers and agencies, led by Peter Kim and Christopher S. Martin, in December 2018.

�

In April 2019, MightyHive merged with ProgMedia to expand operations into Latin America and MediaMonks acquired film studio Caramel Pictures to expand content studio capabilities. In June 2019, MediaMonks announced a planned merger with Australia-based BizTech, a leading marketing transformation and customer experience company. In August 2019, MediaMonks merged with Amsterdam-based digital influencer marketing agency IMA. In October 2019, MediaMonks merged with Firewood Marketing, the largest digital marketing agency based in Silicon Valley, that was recently ranked, along with MediaMonks, as one of the fastest growing agencies by Adweek, and MightyHive merged with award-winning UK-based digital analytics, biddable media and data science company ConversionWorks and South Korea-based data and analytics consultancy Datalicious Korea. In November 2019, MediaMonks merged with Delhi-based content creation and production company WhiteBalance and then with fully integrated digital agency Circus Marketing in January 2020.

�

Victor, Wesley, Pete, Christopher and Peter Rademaker (formerly Chief Financial Officer of MediaMonks, now Chief Financial Officer of S4Capital), all joined the S4Capital Board as Directors. The S4Capital Board also includes Rupert Faure Walker, Paul Roy, Daniel Pinto, Sue Prevezer, Elizabeth Buchanan, Scott Spirit, Naoko Okumoto and Margaret Ma Connolly.

�

The Company has a market capitalisation of approximately �790 million (c.$980 Million) and 2,400 people in 30 countries across the Americas, Europe, the Middle East and Africa and Asia-Pacific. It has achieved Unicorn status in a little over one year, unique in the advertising and marketing services industry.

�

Sir Martin was CEO of WPP for 33 years, building it from a �1 million "shell" company in 1985 into the world's largest advertising and marketing services company with a market capitalisation of over �16 billion on the day he left. Today its market capitalisation is �6.8 billion. Prior to that he was Group Financial Director of Saatchi & Saatchi Company plc for nine years.
