On 3 March 2022, the FCA issued a statement on its website concerning events in Ukraine and the sanctions imposed on Russia, reminding issuers of securities admitted to UK trading venues of their disclosure obligations under the UK Market Abuse Regulation (MAR). The statement goes on to remind companies in scope of MAR that they are required to fulfil their obligations to disclose inside information as soon as possible unless they have a valid reason under the regulation to delay disclosure. This includes continuing to assess carefully what information constitutes inside information, recognising that both the invasion and responses to it by governments globally may alter the nature of information that is material to a business’ assets, operations and prospects. Companies assessing the effect of financial sanctions in all relevant jurisdictions should where necessary take legal advice. The FCA adds that companies should ensure the market is fully informed of any information or changes that are required to be disclosed under MAR. Companies are also reminded that disclosure obligations continue to apply even when trading of securities has been suspended.
