For companies weighing a public listing in Singapore, the first fork in the road is choosing between the SGX Mainboard and Catalist. Both sit on the same exchange and offer access to public capital, but they are built for companies at different stages of growth, with materially different admission criteria and ongoing obligations.

Mainboard: For Established, Profitable Businesses

The Mainboard is SGX’s senior board, designed for larger, more established companies. Admission is assessed against quantitative criteria — typically a combination of profitability track record, market capitalisation, or cash flow with market capitalisation, depending on which admission criterion the company elects to meet. Mainboard-listed companies are generally expected to have a longer operating history and a demonstrated earnings record.

Catalist: A Sponsor-Supervised Route for Growth Companies

Catalist was designed for smaller and growth-stage companies that may not yet meet Mainboard quantitative thresholds. Rather than SGX vetting each admission directly, Catalist operates under a sponsor-supervised model — a full sponsor assesses the company’s suitability for listing and continues to supervise it for a period post-listing. This makes the sponsor relationship, not just the company’s own readiness, a critical factor in a Catalist listing timeline.

Choosing Between the Two

The right board depends on where a company sits today, not just where it aspires to be:

  • Track record — Mainboard suits companies with an established profit history; Catalist suits earlier-stage or fast-growing companies that need a lower quantitative bar to access public markets.
  • Governance readiness — both boards require robust corporate governance, but the sponsor’s ongoing supervisory role on Catalist means a company will work closely with its sponsor well beyond the IPO itself.
  • Long-term signalling — some companies use a Catalist listing as a stepping stone, later transferring to the Mainboard once they meet its criteria, though this is a deliberate decision rather than an automatic progression.

Getting Listing-Ready

Regardless of which board a company targets, the practical work is similar: clean up the corporate structure, tighten financial reporting and internal controls, assemble the right board composition, and build the relationships with sponsors, auditors, and legal counsel well before the listing process formally begins.

Listing rules and thresholds are set by SGX and are subject to change — always confirm current admission criteria directly with SGX or your appointed sponsor before finalising a listing strategy.
