Secondary Listing on the SEM: Guide for CFOs

Published: 2026-10-29 / Updated: 2026-10-29 ・ 8 min read

A secondary listing on the Stock Exchange of Mauritius (SEM) allows an international issuer already listed on a primary venue to list its equity or debt securities in Mauritius without relinquishing its domestic listing. This structure enables cross-border enterprises to access an international investor base, quote shares in major global currencies, and build visibility across African and Indian Ocean investment corridors.

For founders and Chief Financial Officers evaluating overseas capital structures, a secondary listing provides an additional trading facility alongside existing listings on platforms such as the National Stock Exchange of India (NSE), Bombay Stock Exchange (BSE), Johannesburg Stock Exchange (JSE), or Singapore Exchange (SGX). Because exact primary market listing requirements, disclosure obligations, and cross-border transfer mechanics vary significantly by jurisdiction, issuers must consult the official rulebooks of their domestic exchanges before proceeding.

Market Platforms for Cross-Border Issuers

The Stock Exchange of Mauritius operates two main listing platforms, regulated under the oversight of the Financial Services Commission Mauritius:

1. The Official Market: Designed for established operating businesses with longer operational records. At the end of 2025, there were 57 companies listed on this market.
2. The Development & Enterprise Market (DEM): Designed for growth-oriented or small-and-medium enterprises. At the end of 2025, there were 33 companies listed on the DEM.

Beyond domestic enterprises, international participation represents a substantial segment of overall platform activity. Of the 255 new securities listed across the exchange since 2010—encompassing equity, debt, and specialist instruments—124 were issued by international entities, as detailed in SEM at a glance. Additionally, the exchange introduced the Africa Board in October 2018 for businesses where at least half of total assets or revenue originates in Africa outside Mauritius. More recently, SEMX launched in December 2024 as a dedicated growth platform for African businesses.

Eligibility Criteria: Official Market vs. DEM

An international company considering a secondary listing must determine whether its profile aligns with the Official Market or the DEM. Neither market should be assumed to fit every profile; review the explicit criteria established by the exchange.

#### Official Market Eligibility Rules

To qualify for admission to the Official Market, an applicant must satisfy the following thresholds under the Stock Exchange of Mauritius - Official Market requirements:

• Operating Track Record: At least three continuous years of audited financial statements.
• Minimum Valuation: A minimum market capitalisation of MUR 20 million (about USD 420,000, approximate).
• Shareholder Spread: A minimum of 200 public shareholders.
• Free Float: At least 25% of the total issued share capital must be held in public hands. The exchange rules allow for phased implementation of this float: an issuer may open with 15%, step up to 20% within three years, and reach 25% by the close of year five.

#### DEM Eligibility Rules

For companies seeking entry via the alternative board, the Stock Exchange of Mauritius - DEM requirements specify:

• Operating Track Record: A minimum of one year of audited financial statements prepared under International Financial Reporting Standards (IFRS). This condition relates strictly to the presence of compliant accounts, not specific revenue or net profit minimums.
• Alternative Track Record Route: An applicant lacking an operating track record may still apply if it submits a business plan covering at least three years, certified by an independent financial adviser.
• Minimum Valuation: A minimum market capitalisation of MUR 20 million (about USD 420,000, approximate).
• Public Distribution Requirements: The applicant must meet two separate, independent conditions: at least 100 shareholders, and at least 10% of equity held in public hands. The rules do not require that the 10% float be held exclusively by the 100 public shareholders. The SEM may admit an issuer that formally commits to meeting these conditions by the conclusion of its first year of listing.

Professional Roles and Mandatory Appointments

Navigating a secondary listing requires specific market intermediaries depending on the market platform chosen.

#### 1. Official Market Sponsors and Agents

Under the Official Market Listing Rules (Rule 4.2), an issuer must appoint a sponsor registered with the SEM. This sponsor must remain appointed throughout the formal application process and must be retained continuously while the company remains listed. Under Rule 15.4, international issuers are also obligated to appoint a local agent to maintain communication channels and administrative interface in Mauritius.

#### 2. DEM Corporate Advisers

The rules for the DEM differ structurally from those of the Official Market. Under DEM Rule 32, a DEM company shall, as far as reasonably practicable, retain a corporate adviser at all times. The corporate adviser's primary responsibility is to guide the board of directors regarding ongoing regulatory compliance and act as the principal liaison with the exchange. Note that the official DEM Rules do not use the term "sponsor" for this function.

Currency Mechanics and Settlement Infrastructure

A practical consideration for CFOs managing cross-border share quotations is exchange rate settlement. When structuring a secondary listing, companies are not restricted to quoting or trading equity exclusively in local currency.

The SEM trading architecture supports quotation, clearing, and settlement across five currencies:

• United States Dollar (USD)
• Euro (EUR)
• British Pound (GBP)
• South African Rand (ZAR)
• Mauritian Rupee (MUR)

Settlement takes place directly in the nominated listing currency, eliminating foreign currency conversion steps within the exchange system for international transactions.

The Secondary Listing Sequence

Preparing for dual or secondary admission typically proceeds along a defined operational path:

• First, Board Resolution and Primary Market Clearance: The board evaluates dual-listing parameters and confirms that issuing shares or transferring a listing quota to an international market does not breach articles of association or primary domestic stock exchange continuous disclosure obligations.
• Second, Engagement of Required Local Intermediaries: The issuer appoints local legal counsel, auditing counterparts, and either a registered sponsor (for an Official Market admission) or a corporate adviser (for a DEM admission), along with a local agent under Rule 15.4 if applying to the Official Market.
• Third, Documentation Compilation: The core team prepares the listing prospectus or admission document. This file contains the historical audited financial reports (three years for the Official Market; one year of IFRS accounts, or a certified three-year business plan, for the DEM), corporate constitutional papers, and evidence verifying the necessary distribution of shares in public hands.
• Fourth, Exchange and FSC Technical Review: The complete dossier is submitted concurrently to the SEM Listing Executive Committee and the Financial Services Commission (FSC) for technical evaluation, response to queries, and regulatory vetting.
• Fifth, Admission and Technical Quoting: Following formal approval from regulatory committees, trading codes are allocated, register reconciliation between depository systems occurs, and the secondary line opens for cross-market trading.

Continuous Compliance Considerations

Once secondary quotation begins, management must navigate concurrent post-listing reporting across jurisdictions. Official Market and DEM companies must provide periodic financial information, release price-sensitive updates, and notify the SEM of corporate actions simultaneously with filings made on their home platforms.

If any corporate governance discrepancy arises between requirements in the primary listing venue and the SEM rulebooks, issuers should seek formal clarification directly from the exchange or through their appointed adviser.
