IPO Rules Explained: Listing on the Stock Exchange of Mauritius

Published: 2026-10-18 / Updated: 2026-10-18 ・ 6 min read

What are the IPO rules on the Stock Exchange of Mauritius?

The core rule is simple: a company applying to list on the Stock Exchange of Mauritius (SEM) must choose between two markets - the Development & Enterprise Market (DEM) or the Official Market - and meet that market's specific track record, market capitalisation, and shareholder-spread conditions. Both markets are regulated by the Financial Services Commission (FSC), and both require working with named advisers throughout the process, not just at application stage.

This article sets out what each market requires, who is involved, and the general order in which an IPO on the SEM typically proceeds. It does not cover other exchanges' rules in detail - if you are also weighing a listing on the NSE, BSE, JSE or SGX, check each exchange's own rulebook directly, since their thresholds and definitions differ from the SEM's and should not be assumed to match.

SEM basics: two markets, one regulator

The SEM operates under the oversight of the Financial Services Commission Mauritius, which licenses and supervises market participants. The exchange itself is split into:

• The Development & Enterprise Market (DEM) - generally aimed at smaller or earlier-stage companies.
• The Official Market - with a longer track-record requirement and a higher public-float target.

At end-2025, the SEM Factbook recorded 57 companies on the Official Market and 33 on the DEM. Since 2010, 255 new securities (shares, bonds and other instruments - not a count of companies) have been listed, of which 124 came from international issuers. Trading and settlement are available in USD, EUR, GBP, ZAR and MUR, which matters for issuers outside Mauritius weighing currency exposure. See SEM at a glance for more on international issuer activity.

DEM eligibility: the entry-level route

The DEM's admission conditions, as set out by the exchange, include:

• One year of audited IFRS financial statements. This is a requirement to have audited accounts prepared under IFRS for at least one year - it is not a profit or revenue test.
• Minimum market capitalisation of MUR 20 million (about USD 420,000, approximate).
• At least 100 shareholders, and at least 10% of shares in public hands - these are two separate conditions, not one combined requirement. The 10% does not need to be spread across all 100 shareholders.
• A no-track-record route: a company without a trading history may still apply if it submits a business plan covering at least three years, certified by an independent financial adviser.

The SEM may admit a company that commits to meet the shareholder and public-float conditions by the end of its first year, rather than at the point of listing. Full detail sits in the DEM admission requirements published by the exchange, and founders should confirm current figures directly with the SEM or a qualified adviser before relying on them in a filing.

Under DEM Rule 32 (DEM Rules, amended November 2019), a company must, as far as reasonably practicable, retain a corporate adviser at all times it is listed. This adviser's role is to guide directors on their compliance obligations and to liaise with the SEM on the company's behalf. The DEM Rules do not use the word "sponsor" - that term applies to the Official Market, not the DEM, and the two roles should not be used interchangeably.

Official Market: the senior route

The Official Market asks for a longer history and wider public ownership:

• Three years of financial statements.
• Minimum market capitalisation of MUR 20 million.
• At least 200 shareholders, and at least 25% of shares in public hands - again, two distinct conditions. The 25% public float may be phased: 15% at listing, rising to 20% within three years, and 25% by year five.

These figures come from the Official Market admission requirements page, and, as with the DEM, should be confirmed with the exchange or a qualified adviser before an issuer relies on them for planning purposes.

Under the Official Market Listing Rules (Rule 4.2), a company must appoint a sponsor registered with the SEM, both while its application is being prepared and for as long as it remains listed. International issuers listing on the Official Market must also appoint a local agent under Rule 15.4 - a Mauritius-based point of contact for the company's dealings with the exchange.

Sponsors and advisers: who does what

The two roles sound similar but are defined differently depending on the market:

• DEM corporate adviser (DEM Rule 32) - advises directors on ongoing compliance and acts as the liaison with the SEM. Required "as far as reasonably practicable" for the life of the listing.
• Official Market sponsor (Rule 4.2) - a sponsor registered with the SEM, required during the application process and throughout the listing.
• Local agent (Rule 15.4) - required specifically for international issuers on the Official Market.

Founders comparing venues should treat these as distinct appointments with distinct rulebooks, rather than assuming one adviser relationship covers both markets' requirements.

Typical sequence for an SEM listing

While exact timing depends on the company and cannot be guaranteed, the general shape of a listing process on the SEM follows this pattern:

1. Choose a market - DEM or Official Market - based on track record, ownership structure and future float plans.
2. Appoint advisers - a corporate adviser for the DEM, or a sponsor (and local agent, if international) for the Official Market.
3. Prepare financial statements - one year of audited IFRS accounts for the DEM, or three years for the Official Market, or a certified three-year business plan for a DEM applicant without a track record.
4. Structure the public float - plan toward the applicable shareholder count and public-hands percentage, noting the DEM's option to phase this in during the first year and the Official Market's phasing option over five years.
5. Submit the application through the appointed sponsor or corporate adviser, who liaises with the SEM on the company's behalf.
6. Ongoing compliance after admission - continued engagement with the corporate adviser or sponsor, and adherence to the relevant rulebook for as long as the company remains listed.

A note on newer platforms

The SEM has also introduced SEMX, a growth platform for African businesses launched in December 2024, and an Africa Board launched in October 2018 for companies with at least half of their assets or revenue in Africa outside Mauritius. Readers interested in either should confirm current eligibility criteria directly with the exchange, since this article does not cover their detailed rules.

Next steps

Companies weighing the SEM against a home-market listing should treat the figures above as a starting point, not a final checklist - rules are amended from time to time, and an applicant's specific structure (international versus domestic, track record versus business plan) changes which conditions apply.

FAQ

Q. What are the basic IPO rules for listing in Mauritius?

A. The Stock Exchange of Mauritius runs two markets - the Development & Enterprise Market (DEM) and the Official Market - each with its own track record, shareholder-spread and public-float requirements, overseen by the Financial Services Commission. See the [DEM requirements](https://stockexchangeofmauritius.com/listing-issuer-services/listing-on-sem/admission-requirements/dem) and [Official Market requirements](https://stockexchangeofmauritius.com/listing-issuer-services/listing-on-sem/admission-requirements/official-market).

Q. Can a company with no trading history list on the SEM?

A. On the DEM, a company without a track record may apply with a business plan covering at least three years, certified by an independent financial adviser, instead of audited financial statements.

Q. Does the SEM require a sponsor for every listing?

A. No. The Official Market requires a registered sponsor under Rule 4.2 of the Official Market Listing Rules; the DEM instead requires a corporate adviser under DEM Rule 32, a related but distinct role.
