OSLO BØRS TRANSITIONS NORWEGIAN LISTED COMPANIES TO EURONEXT'S PROPRIETARY TRADING PLATFORM OPTIQ®

THE MIGRATION TO OPTIQ®, EURONEXT'S PROPRIETARY TRADING PLATFORM, ENABLES OSLO BØRS LISTED COMPANIES AND TRADING MEMBERS TO BENEFIT FROM EURONEXT'S PAN-EUROPEAN SINGLE ORDER BOOK

Amsterdam, Brussels, Dublin, Lisbon, London, Oslo and Paris - 2 December 2020 - Euronext today announced the successful migration of the 276 companies with equities currently listed in Oslo to the Euronext single order book empowered by the proprietary trading platform, Optiq®. This milestone is reached 17 months after Oslo Børs joined Euronext and 21 months after Euronext Dublin's successful migration to Optiq®.

Companies listed on Oslo Børs will gain access to the largest liquidity pool of international capital in Europe, powered by a single order book. 1,500 issuers are now listed on Euronext's exchanges, in Amsterdam, Brussels, Dublin, Lisbon, Oslo and Paris, for an aggregated market capitalisation of over €4.4 trillion as of end November 2020.

Being listed on Euronext' integrated markets will allow companies listed in Oslo to benefit fully from Euronext's proprietary issuer services, which include the online Connect portal of companies' trading data. Euronext also proposes corporate services such as webinars and webcasts, an investor relationship management and targeting platform for corporate investor relations teams, strategic analyses of shareholding structure, tailor-made IR and ESG advice, a board portal and an insider list management tool1.

As part of this transition on 30 November 2020, Oslo Børs has changed the name of three marketplaces to align with the rest of the Euronext group. 'Oslo Axess' has been renamed 'Euronext Expand', 'Merkur Market' is now 'Euronext Growth', and 'NOTC' is 'Euronext NOTC'. There have been no substantive rule changes or functionality changes to these markets.

Øivind Amundsen, CEO of Oslo Børs and member of the Managing Board of Euronext, said: "Oslo Børs is the central marketplace for the listing and trading of financial instruments in the Norwegian market. For over 200 years, we have given companies access to the necessary capital to finance growth, innovation and new jobs. With Optiq®, Oslo becomes part of the largest liquidity pool in Europe, giving companies listed in Oslo increased visibility and a larger investor audience. Euronext is the number one exchange in Europe for SME listing, with a special focus on technology. This complements our leading position within the energy, shipping and seafood sectors, where Oslo attracts companies from all over the world."

Stéphane Boujnah, CEO and Chairman of the Managing Board of Euronext, said: "Optiq® is the pillar of our ambition to build the leading pan-European market infrastructure. Our state-of-the-art, multi-market trading platform provides customers with maximum flexibility, simplified and harmonised messaging as well as high performance and stability, as demonstrated during the recent volatility peaks. This migration is a key milestone in the integration roadmap of Oslo Børs as Norwegian stakeholders will now be able to leverage the full power of the Euronext single liquidity pool enabled by a single order book. I am proud to see how the whole Euronext organisation has worked together towards this milestone despite the coronavirus pandemic, and only 17 months after we completed the Oslo Børs VPS acquisition."
