The UK ceased to be a Member State of the European Union on 31 January 2020. A transition period then applied until 31 December 2020. During the transition period, EU law continued to apply in and to the UK, and the UK continued to trade as part of the Single Market.

The Brexit transition period ended on 31 December 2020, with the EU and UK having agreed to the terms of their future relationship through a Trade and Cooperation Agreement – you can read more about the implications of the agreement here.

Retained EU law

As of 1 January 2021, EU law no longer applies in the UK. By virtue of the European Union (Withdrawal) Act 2018, directly applicable EU law in force in the UK at the end of the transition period is retained as part of the UK statute book. Retained EU law has broadly the same status as any other UK enactment and is subject to the same rules/processes for amendment as any other UK primary or secondary legislation (or if made under devolved powers, the rules of the relevant legislature in Scotland, Wales or Northern Ireland).

EU Exit statutory instruments

The Government has made secondary legislation dealing with a range of corporate law matters to ensure that both Retained EU law and existing UK law and regulation (for example that referenced EU concepts or bodies) could operate effectively once the transition period ended. These regulations include:

FCA Rules

The FCA has made a number of changes to its Handbook that apply with effect from the end of the Brexit transition period, including changes to the Listing, Prospectus Regulation, Disclosure Guidance and Transparency Rules.

The impact of the rule changes for UK incorporated companies which have securities admitted only to a UK regulated market will be minimal. Issuers which have shares admitted to a regulated market in the UK and in an EEA state will have to adjust their systems and controls and, for example, make additional notifications to regulators for certain matters, including in relation to PDMR transactions.

Takeover Code

The Takeover Panel has similarly made a number of changes to the Takeover Code that were required as a result of Brexit. The changes will not have a significant impact on transactions.
