What is required when a company shifts from AIM to an official list without issuing new share capital?

When a company transitions from the Alternative Investment Market (AIM) to the official list of the London Stock Exchange without issuing new share capital, it is necessary to prepare a prospectus. A prospectus serves as a detailed document that provides potential investors with important information about the company, including its business operations, financial situation, and risks associated with investing.

The prospectus requirement is crucial in ensuring transparency and protecting investor interests during this transition, as it helps to inform the market about the company's move to a more regulated listing. This requirement for a prospectus applies even when no new shares are being issued, making it an essential step in the process of upgrading to a full listing.

In this context, shareholder approval and public announcements may also be relevant, but they are not a formal requirement specifically tied to the transition itself, especially regarding the absence of new share capital issuance. Therefore, the prospectus requirement stands out as the key obligation that must be fulfilled in this scenario.
