AIM rule 15 (May 2014)17 Oct 2016 11:44
Fundamental changes of business
15. Any disposal by an AIM company which, when aggregated with any other disposal(s) over the previous twelve months, exceeds 75% in any of the class tests, is deemed to be a disposal resulting in a fundamental change of business and must be:
conditional on the consent of its shareholders being given in general meeting;
notified without delay disclosing the information specified by Schedule Four and insofar as it is with a related party, the additional information required by rule 13; and
accompanied by the publication of a circular containing details of the disposal and any proposed change in business together with the information specified above and convening the general meeting.
Where the effect of the proposed disposal is to divest the AIM company of all, or substantially all, of its trading business, activities or assets the AIM company will, upon completion of the disposal, be treated as an investing company. The notification and circular containing the information specified by Schedule Four convening the general meeting must also state its investing policy to be followed going forward which must also be approved by shareholders.
The AIM company will then have to make an acquisition or acquisitions which constitute a reverse takeover under rule 14 or otherwise implement the investing policy approved at the general meeting to the satisfaction of the Exchange within twelve months of becoming an investing company.
Where an AIM company proposes to take any other action, the effect of which is that it will cease to own, control or conduct all, or substantially all, of its existing trading business, activities or assets (including the cessation of all, or substantially all, of the AIM company’s business), the above requirements to notify the action, publish a circular setting out its investing policy going forward, obtain shareholder consent for that investing policy and implement it within twelve months of taking such action, will apply. Shareholder consent for the action itself will not be required.
