Presentation of the Group 1 Description of the Business

Launch of Tech Leaders In 2022, Euronext announced the launch of Tech Leaders, a segment dedicated to highlighting the visibility and attractiveness of high-growth listed Tech companies among international investors, together with a suite of services to support them throughout their financial journey. Alongside this segment, Euronext is launching a full suite of pre-IPO services to attract private Tech listing candidates to Euronext’s markets, supporting their growth financing needs. Euronext’s Tech Leaders segment will provide listed Tech companies with enhanced visibility among Euronext’s large international investor base, as well as access to the largest financing liquidity pool in Europe, which attracted 25% of European share trading activity in 2021 via the Optiq® trading platform. The Tech Leaders segment will be composed of innovative and high-growth Tech companies that are listed on Euronext markets and comply with a set of financial and non-financial criteria that set them apart in terms of market capitalisation, free-float, and growth profile. Tech companies listed on this segment will benefit from increased visibility towards investors and services to facilitate their access to financing throughout their growth journey. This initiative includes a comprehensive offering of pre-IPO services to support future listings of high-growth Tech companies, leveraging on Euronext’s flagship pre-IPO programme TechShare. Euronext will offer executive training and coaching, advisory services and corporate access to investors, to prepare private Tech companies for their potential future IPO. Euronext will develop and deploy these initiatives in close cooperation with both public and private institutions. Subject to regulatory approval where relevant, the composition of the Tech Leaders segment and details of the services offered will be announced during Q2 2022.
