Dual Listing Explained: Adding the Mauritius Exchange

Published: 2026-10-24 / Updated: 2026-10-24 ・ 6 min read

What Is a Dual Listing on the SEM?

A dual listing means a company keeps its existing listing on its home exchange and adds a second listing on the Stock Exchange of Mauritius (SEM), rather than moving its listing from one venue to the other. The company's shares (or a related instrument such as a depositary receipt) then trade under two separate rulebooks, with reporting obligations to both exchanges.

For founders and CFOs already listed in India, Southern or East Africa, or elsewhere in Asia, a dual listing on the SEM is usually explored for reasons such as access to a different investor base, trading in multiple currencies, or positioning alongside other international issuers. This article explains how the structure works on the SEM side and what to check before going further — it does not recommend for or against the move.

Dual Listing vs Primary Listing: The Difference That Matters

It helps to separate two ideas that get mixed up:

• Primary (sole) listing on the SEM — the company's only listing is on the DEM or the Official Market of the SEM.
• Dual listing — the company keeps its home-market listing and adds a second, parallel listing on the SEM.

The SEM's own admission requirements do not change depending on which of these applies — a company applying for a dual listing still has to meet the same DEM or Official Market criteria as a company seeking its only listing in Mauritius. What differs is the extra coordination: matching disclosure timetables, reconciling corporate actions across two markets, and deciding which exchange's requirements apply when they overlap.

The Two SEM Markets Available for a Dual Listing

The SEM operates two markets, and a dual-listing applicant chooses (or is assessed for) one of them, not both.

Development & Enterprise Market (DEM)

The DEM asks for:

• One year of audited IFRS financial statements
• Minimum market capitalisation of MUR 20 million (about USD 420,000, approximate)
• At least 100 shareholders, and, as a separate condition, at least 10% of shares in public hands
• A corporate adviser retained "as far as reasonably practicable" at all times, as set out in DEM Rule 32 (DEM Rules, amended November 2019) — the adviser guides directors on compliance and liaises with the SEM

A company without a trading track record may still apply, provided it submits a business plan covering at least three years, certified by an independent financial adviser. Full detail is on the Stock Exchange of Mauritius - DEM requirements page.

Official Market

The Official Market asks for:

• 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 (this percentage may be phased in — 15%, then 20% within three years, then 25% by year five)
• A sponsor appointed both while the application is being prepared and throughout the listing (Official Market Listing Rules, Rule 4.2)
• A local agent appointed if the issuer is international (Rule 15.4)

Details sit on the Stock Exchange of Mauritius - Official Market requirements page. For a company already listed elsewhere and considering a dual listing on the Official Market, the local-agent requirement under Rule 15.4 is the one most often overlooked — it applies specifically because the issuer is based outside Mauritius.

Who Does What in a Dual-Listing Application

A dual listing involves more coordinating parties than a sole listing, because two regulatory relationships run in parallel:

1. The company's board and CFO office — prepare financial statements under IFRS, coordinate the business plan (if applying as a no-track-record case on the DEM), and manage disclosure consistency across both markets.
2. A corporate adviser (DEM) or sponsor (Official Market) — the DEM Rules do not use the word "sponsor"; a DEM applicant retains a corporate adviser, while an Official Market applicant appoints a sponsor under Rule 4.2.
3. A local agent — required for international issuers on the Official Market under Rule 15.4; typically handles matters requiring a Mauritius-based point of contact.
4. The home exchange's own advisers — your existing listing sponsor, broker, or legal counsel at home, who confirm what your primary exchange requires when a dual listing is added (rules vary by exchange — check the official rulebook of your home market directly).
5. The Financial Services Commission — the Mauritius regulator for SEM-listed securities; see the Financial Services Commission Mauritius for its role.

A typical sequence starts with an internal feasibility review (which market, DEM or Official Market, fits the company's size and shareholder spread), followed by appointing the corporate adviser or sponsor, preparing the financial statements and application documents, and then submitting to the SEM while keeping the home regulator informed, since many home-market rules require prior notice or approval before a company lists abroad.

Currency and Market Context

The SEM supports trading and settlement in USD, EUR, GBP, ZAR and MUR, which is one reason companies with revenue or investors outside Mauritius look at a dual listing there. At end-2025, the SEM had 57 companies on the Official Market and 33 on the DEM; of 255 new securities listed since 2010 (counting shares, bonds and other instruments, not a count of companies), 124 came from international issuers. Background on market structure is available at SEM at a glance.

The SEM also operates an Africa Board, launched in October 2018, for companies with at least half of their assets or revenue in Africa outside Mauritius, and SEMX, a growth platform for African businesses launched in December 2024. Readers considering whether either applies to a dual-listing structure should confirm current criteria directly with the exchange or a licensed adviser.

Points to Confirm Before Applying

Because a dual listing touches two sets of rules at once, a few items are worth confirming early rather than assuming:

• Whether your home exchange's rulebook requires its own approval, notification, or a specific structure (such as depositary receipts) before a second listing abroad
• Which SEM market — DEM or Official Market — matches your shareholder count and public float, since the thresholds differ materially
• Whether the 10% (DEM) or 25% (Official Market, phased) public float condition can be met at admission or needs to be phased in
• Whether your audited financial statements already meet IFRS, since both SEM markets require this

FAQ

Q. Does a dual listing mean my shares trade on two exchanges at once?

A. Yes, in principle — the same class of securities (or depositary receipts representing them) is admitted to trading on two separate exchanges, each with its own rulebook, regulator contact point, and ongoing disclosure obligations.

Q. Can a company list only on the SEM without a dual listing?

A. Yes. Companies can seek a primary listing on the DEM or the Official Market of the SEM without maintaining a listing anywhere else. A dual listing is one option among several, not a requirement.

Q. Who regulates a dual-listed company in Mauritius?

A. The Financial Services Commission is the Mauritius regulator for SEM-listed issuers. If you are dual-listed, your home exchange's regulator continues to oversee your primary listing as well — confirm the exact split of obligations with a licensed adviser.
