Requirements to Go Public: SEM Listing Rules Explained

Published: 2026-10-20 / Updated: 2026-10-20 ・ 6 min read

What It Takes to Go Public on the SEM

The requirements to go public on the Stock Exchange of Mauritius differ depending on whether a company targets the Development & Enterprise Market (DEM) or the Official Market. Both markets are regulated by the Financial Services Commission (FSC), and both set thresholds for financial track record, market capitalisation, and the number and proportion of shares held by the public.

This article sets out what each market asks for, who typically does what in the process, and the usual order of steps — without naming fees, promising timelines, or guaranteeing any outcome.

Quick Answer

For the DEM: one year of audited IFRS financial statements, minimum market capitalisation of about MUR 20 million (about USD 420,000, approximate), at least 100 shareholders, and at least 10% of shares in public hands — these last two are separate conditions, not one combined rule. A company with no track record may still apply using a business plan covering at least three years, certified by an independent financial adviser.

For the Official Market: three years of financial statements, the same MUR 20 million minimum market capitalisation, at least 200 shareholders, and at least 25% in public hands, which may be phased — 15%, then 20% within three years, reaching 25% by year five.

Full detail sits with the exchange: see the DEM requirements and Official Market requirements.

DEM Eligibility in Detail

The Development & Enterprise Market is generally the route considered by smaller or younger companies. The headline conditions are:

• One year of audited IFRS financial statements. This is about the existence of audited accounts, not a profit or revenue threshold.
• Minimum market capitalisation of about MUR 20 million (about USD 420,000, approximate) at the time of listing.
• At least 100 shareholders.
• At least 10% of shares in public hands. This is a separate test from the shareholder count — a company could technically meet one without automatically meeting the other, so both need checking independently.
• No-track-record route: a company that cannot show the one-year audited 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 meeting the shareholder and public-float conditions by the end of its first year of listing, rather than at the point of admission — founders should confirm the current position directly with the exchange or an adviser, since this kind of phasing detail can be refined over time.

Official Market Requirements in Detail

The Official Market is generally the route for larger, more established companies. Its conditions are more demanding on track record and public float:

• Three years of financial statements.
• Minimum market capitalisation of about MUR 20 million.
• At least 200 shareholders.
• At least 25% of shares in public hands, which may be phased in: 15% at listing, rising to 20% within three years, and reaching 25% by year five.

Because the phasing option exists, a company planning an Official Market listing should map out, year by year, how it intends to reach the full public float requirement — this is a point worth discussing early with a sponsor rather than close to application.

Sponsors and Corporate Advisers: Who Does What

The two markets use different terminology and different ongoing obligations:

• Official Market: under the Official Market Listing Rules (Rule 4.2), a sponsor registered with the SEM must be appointed both while the application is being prepared and for as long as the company remains listed. International issuers listing on the Official Market must also appoint a local agent (Rule 15.4).
• DEM: the DEM Rules (amended November 2019), Rule 32, require a company to retain a corporate adviser "as far as reasonably practicable" at all times. The corporate adviser guides directors on compliance with the DEM Rules and acts as the liaison with the SEM. The DEM Rules do not use the word "sponsor" — it is a distinct role with its own name and scope.

In practice, the sponsor or corporate adviser is usually the party coordinating the listing application, reviewing disclosure documents, and acting as the main point of contact with the exchange. Founders comparing venues should ask any adviser they're considering to set out exactly which rule governs their appointment and what ongoing duties follow listing.

Typical Sequence for a Listing Application

While exact steps and timing should always be confirmed with the exchange or an adviser, a typical sequence for either market generally includes:

1. Choice of market (DEM or Official Market) based on track record, size, and how much public float the company can realistically commit to.
2. Appointment of a sponsor (Official Market) or corporate adviser (DEM), and — for international issuers on the Official Market — a local agent.
3. Preparation of financial statements (one year audited IFRS for DEM, three years for Official Market) or, for DEM applicants without a track record, a three-year business plan certified by an independent financial adviser.
4. Confirmation of shareholder base and public float, checked against the applicable thresholds.
5. Submission of the listing application to the SEM, with supporting documents reviewed by the sponsor or corporate adviser.
6. SEM review and, where relevant, FSC regulatory engagement.
7. Admission to trading, after which ongoing obligations — continued retention of the sponsor or corporate adviser, periodic disclosure, and maintenance of public float — apply.

No step here should be read as a guaranteed timeline; processing periods and specific document lists are set by the exchange and should be confirmed directly.

Where This Sits Within the Wider SEM

At the end of 2025, the SEM listed 57 companies on the Official Market and 33 on the DEM, according to the SEM Factbook 2026. Since 2010, 255 new securities (shares, bonds and other instruments, not a count of companies) have listed, of which 124 came from international issuers. Trading and settlement are available in USD, EUR, GBP, ZAR and MUR, which is relevant for companies with revenue or investors outside Mauritius. More background is available at SEM at a glance.

The exchange has also introduced more specialised platforms: SEMX, a growth platform for African businesses, launched in December 2024, and the 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 detailed rules for these platforms are not covered here.

Comparing This With a Home Exchange

Exchanges such as the NSE, BSE, JSE or SGX each publish their own listing board structures, minimum capital and shareholder spread requirements, and sponsor or underwriter obligations. These vary by board and change periodically, so rather than stating specific numbers here, founders comparing the SEM against a home-market listing should check the current rulebook of that exchange directly before making any comparison.

Next Steps

Confirming current numerical thresholds, required documents, and sponsor or corporate adviser obligations directly with the Stock Exchange of Mauritius or the Financial Services Commission Mauritius is the appropriate first step before any listing decision.

FAQ

Q. What is the minimum number of shareholders needed to list on the SEM?

A. The DEM requires at least 100 shareholders and separately at least 10% of shares in public hands. The Official Market requires at least 200 shareholders and at least 25% in public hands, which may be phased in over five years. 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, yes in principle: a company without a track record may apply with a business plan covering at least three years, certified by an independent financial adviser, in place of audited financial history.

Q. Do I need a sponsor to list on the SEM?

A. Terminology differs by market. The Official Market Listing Rules (Rule 4.2) require a registered sponsor during the application and while listed. The DEM Rules instead require a corporate adviser to be retained, as far as reasonably practicable, at all times (Rule 32). Confirm current requirements with the exchange or an adviser.
