Presentation of the Group

Regulation

X2M delivers bespoke solutions designed and supported to meet the needs of the financial community. X2M services are certified ISO 22301:2019, ISO/IEC 27001:2013 and ISO/IEC 20000-1:2018. The Technologies & Other business benefits from the technology developments made by Euronext for its own markets and, in return, contributes recurring revenue that is non-cyclical and not trading related. Operating as a technology vendor also gives Euronext an opportunity to benchmark both its technology and support services against other vendors and ensure that it maintains its position at the forefront of the industry. The solutions and services offered use the products and services developed by the Euronext group or licensed from third parties. Historically, revenue from the Euronext Technology Solutions & Other business came from software licences and maintenance fees. Post the Borsa Italiana acquisition, with the inclusion of Gatelab and X2M to the Technology Solutions business, the revenue streams will become more diversified and be generated from the combination of connectivity services, comprising colocation, network and proximity services, alongside innovative products providing: data analytics, risk management services, order management system (“OMS”) broker workstations, algorithmic trading validation, and regulatory reporting services. Euronext’s main strategic ambition is to provide secure and direct access to the main European liquidity centres from its Bergamo Core Data Centre facility, alongside access to a set of products covering the full trading cycle, from pre-trade insight (data) to asset allocation, portfolio modelling & construction, execution, and regulatory compliance. This is based on a value proposition created through combining ease of access and a rich set of products and services offered both to Euronext’s market participants and to other financial firms.

EU and the UK. These services provide regulatory reporting facilities to investment firms. With the integration of both Gatelab and X2M into Euronext Technology Solutions following the Borsa Italiana Group acquisition in 2021, the provision of services will be extended to financial institutions, alongside the services already provided to trading venues. Gatelab, part of the Euronext group, is a leading provider of trading and market access solutions to the global financial community. Founded in 1989, Gatelab offers scalable low-latency solutions to support market- makers, price-takers and brokers in pre-trade, trading, and post-trade operations across venues of any asset class.
