Following a review of listing arrangements, the Board decided to cancel the Company's listing on the Irish Stock Exchange while maintaining its Premium Listing on the London Stock Exchange. This was a logical development as three quarters of the Group's revenue has for some time been generated in the UK and most of the Group's development activity is taking place outside of Ireland. These changes facilitated the inclusion of Grafton in the FTSE 250 and exposes the Group to a wider pool of international investors.
