AIM Listing Requirements

The listing requirements on the Alternative Investment Market (AIM) of the London Stock Exchange (LSE) are non-prescriptive.  There is no minimum public float, no minimum initial equity, no minimum market capitalization and no minimum level of profitability.  In fact, a company does not even have to have a trading (i.e. operating) history in order to list on London's AIM, although, if this is the case, there will be a mandatory, one year, post-IPO lock up for certain of the company's existing shareholders.

Suitability for listing on London's AIM is at the sole discretion of the company’s Nominated Adviser or “Nomad”.  Once listed, there are no minimum share price or market capitalization requirements.  While very few AIM-listed companies have had their shares suspended from trading on AIM, the most common reason is failure to timely file their half yearly or annual reports with the London Stock Exchange.
