The Stock Exchange of Mauritius: a gateway to capital

With a market capitalisation exceeding USD 10 billion and around forty listed companies, the SEM offers companies structured access to capital markets, for Mauritian companies as well as African and international businesses. Listing can be considered as early as company formation in Mauritius, by structuring the entity with this prospect in mind.
