RE: Moving from AIM to larger LSE?14 Apr 2017 09:47
Some do, some don't, it's not an automatic 'promotion' situation. There are advantages to moving (greater exposure to institutional investment, easier fundraising, possibility of progressing to the FTSE 250 or even - you can always dream - the FTSE 100, prestige) and disadvantages (cost, administration, tighter regulation).
The only requirements for entry to the main market are 3 years of accounts and a market cap. of >£0.7m (DGB are £59m). There some massive companies still on AIM for some reason, like ASC (over £4bn).
Great choice for your first UK investment, buddy.
