Borr Drilling Commences Trading on Euronext Oslo Børs Main List

Borr Drilling Limited announced the commencement of trading of its shares on Euronext Oslo Børs (main list) effective May 21, 2026, following approval from the Norwegian Financial Supervisory Authority. The company's shares will trade under the ticker "BORR" and will be simultaneously deregistered from Euronext Growth Oslo. A prospectus was approved on May 20, 2026, and made available on the company's website. The company's primary listing remains on the New York Stock Exchange (NYSE). This represents an upgrade from the Euronext Growth Oslo secondary market to the main Euronext Oslo Børs exchange, potentially increasing visibility and liquidity for European investors while maintaining its NYSE primary listing.
