Dual Listing on SGX and Nasdaq: The Global Listing Board Explained

The short answer: how an SGX Nasdaq dual listing in Singapore works

As of October 2026, an SGX Nasdaq dual listing in Singapore is available through SGX's new Global Listing Board (GLB). The legislative and rule framework took effect on 29 June 2026. It lets a large issuer list on the Nasdaq Global Select Market and on SGX using a single set of offer documents built on US disclosure standards, rather than preparing a separate Singapore prospectus from scratch.

The route is not for everyone. An issuer needs a market capitalisation of at least S$2 billion at admission, must meet financial standards aligned with Nasdaq Global Select Market initial listing standards, and must raise a meaningful Singapore tranche through The Central Depository. In return, it gets access to US and Asian investors, Singapore trading hours and a streamlined disclosure and liability regime.

This article explains eligibility, the single offer document pathway, the Singapore fundraising requirement, ongoing obligations and the practical questions boards should ask.

What changed and when

SGX and Nasdaq announced their collaboration on 19 November 2025. MAS and SGX RegCo published consultation papers on 9 January 2026 and their responses on 30 April 2026. Parliament passed the Securities and Futures (Amendment) Bill on 7 May 2026, and the resulting Act and the GLB rules took effect on 29 June 2026, as announced in an MAS media release on the dual-listing framework.

The amendments insert a new Part 13A into the Securities and Futures Act 2001 and are supported by subsidiary legislation, including the Securities and Futures (Part 13A) (Global Listing Board and U.S. Exchange) Regulations 2026. SGX's admission and continuing listing requirements for the board sit in the GLB rules published in the SGX Rulebooks. Some amendments to Part 13 of the SFA apply to all offers, not just GLB issuers, including earlier retail engagement using a lodged preliminary prospectus.

Who is affected: high-growth and established companies, often headquartered in Southeast Asia, that want US valuation benchmarks and Asian investor access without running two unrelated listing processes; their underwriters and issue managers; and Singapore retail and institutional investors.

Eligibility for the Global Listing Board

Admission turns on size, quality and a genuine Singapore offering. The key requirements are as follows.

• Market capitalisation: at least S$2 billion at admission.
• Financial standards: revenue, income, assets and equity tests aligned with Nasdaq Global Select Market initial listing standards and calibrated to the S$2 billion threshold.
• Singapore tranche: at least 15% of global IPO value or S$75 million, whichever is higher, unless SGX decides otherwise, settled through and deposited with The Central Depository (Pte) Limited.
• Retail broker tranche: within the Singapore tranche, at least 5% of its value or S$50 million, whichever is lower, reserved for designated retail brokers, with unmet demand reallocated.
• Issue manager: an accredited issue manager must be appointed.
• Local interface: two authorised representatives as the main channel with SGX, and sufficient connection to Singapore for effective local representation.

SGX retains discretion over admission and continued listing. Absent exceptional regulatory or public interest concerns, an issuer approved for the Nasdaq Global Select Market will generally be regarded as suitable. That is a significant change in mindset: SGX is largely relying on the US review rather than duplicating it.

The single offer document pathway

The central feature of an SGX Nasdaq dual listing in Singapore is that one set of offer documents serves both markets. The GLB Regulations incorporate US disclosure requirements into Singapore prospectus and offer information statement requirements, and documents can be incorporated by reference where US law permits. The general disclosure requirement in the SFA that normally applies to a Singapore prospectus is disapplied for GLB issuers.

Several timing and marketing rules were aligned with US practice:

• Filing a US registration statement before lodging the Singapore preliminary prospectus is not treated as a breach of Singapore advertising restrictions.
• Testing-the-waters meetings and free writing prospectuses are permitted in Singapore where US law allows them.
• Pre-deal investor education may be carried out with institutional and accredited investors.
• The Singapore rule that keeps an offer open for a period after a supplementary or replacement document is disapplied for GLB offers, so timetables can track the US deal.

What did not change is accountability. Singapore prospectus liability provisions continue to apply, experts must still give written consent to inclusion of their reports, and issue managers remain responsible for due diligence, though they may use alternative steps where appropriate for GLB-specific risks. Safe harbours are available for forward-looking statements, share repurchases and pre-determined trading plans, and MAS may grant exemptions so that price stabilisation broadly follows US practice.

Process: from Nasdaq approval to SGX trading

The sequence below shows how an SGX Nasdaq dual listing in Singapore typically runs, with the US process setting the pace.

1. Test the fit. Confirm the S$2 billion market capitalisation and Nasdaq Global Select Market financial standards are realistically met at pricing, not just on paper.
2. Assemble the team. Appoint US counsel, Singapore counsel, an accredited issue manager, underwriters and auditors who can work to both regimes, and choose two authorised representatives.
3. Prepare one document set. Draft the US registration statement as the core offer document, with the Singapore wrapper required by the GLB Regulations and SGX rules.
4. Engage investors carefully. Use testing-the-waters and pre-deal investor education only within the limits permitted, and coordinate any retail engagement in Singapore with the preliminary prospectus lodged with MAS.
5. Structure the Singapore tranche. Size the Singapore tranche and the retail broker tranche to meet SGX thresholds, and arrange CDP settlement.
6. Price and list. Run a single book-building timetable aligned with Nasdaq, with stabilisation arrangements consistent with any MAS exemption.
7. Switch on continuing obligations. From day one, announce US filings and material disclosures on SGXNet in a timely way.

GLB compared with other SGX routes

Trade-offs of an SGX Nasdaq dual listing in Singapore

The benefits are clear: one disclosure standard, one book-building timetable, access to US institutional demand and trading during Asian hours. For an issuer with a large Asian customer or shareholder base, an SGX Nasdaq dual listing in Singapore can also support brand recognition and liquidity in its home region.

The costs are less obvious. The issuer takes on the full weight of US securities regulation, including periodic reporting, internal control expectations and US litigation exposure, together with Singapore prospectus liability and SGX continuing obligations. It must fund a Singapore syndicate and retail broker arrangements, and it needs people in Singapore who can deal with SGX quickly. Boards should weigh whether the incremental Singapore liquidity justifies that second layer of compliance.

Timing is another trade-off. Because the Singapore process is aligned with the US timetable, the US review effectively sets the pace. Delays at the US end delay the Singapore tranche too, and an issuer cannot easily proceed in Singapore alone if the Nasdaq listing stalls.

Finally, valuation volatility matters. The S$2 billion threshold is assessed at admission, so a falling market between filing and pricing can push a marginal candidate below the line. Issuers near the threshold should have a fallback plan, such as a Mainboard listing or a deferred GLB application.

For most mid-sized companies, the traditional Mainboard or Catalist route remains the realistic option. The GLB is aimed at issuers large enough to command US institutional demand. Our guide to an IPO on SGX via Catalist or Mainboard covers those alternatives.

Ongoing obligations after listing

Listing is the start, not the end, of an SGX Nasdaq dual listing in Singapore. A GLB issuer must announce on SGXNet all EDGAR filings, including third-party filings, together with other material disclosures required under US securities laws and Nasdaq listing rules, in a timely manner. Listing timelines and submission processes are harmonised with Nasdaq's, which reduces duplication but leaves no room for slippage in the Singapore feed.

On delisting, SGX reviews voluntary applications case by case and may impose conditions. It may delist an issuer on public interest and market integrity grounds or under specific triggers in the GLB rules. Where Nasdaq directs a delisting, SGX generally aligns with Nasdaq's process, including notice periods where practicable. In practice, the US listing is the anchor: losing it puts the Singapore listing in question.

Governance expectations also deserve attention. Boards should not assume that every SGX Mainboard governance expectation applies, nor that none do. The allocation of governance, takeover and shareholder-protection rules depends on the issuer's place of incorporation and listing structure, and should be mapped with advisers before the prospectus is finalised. Our corporate governance advisory team can help with that mapping.

Illustrative scenario: a regional technology group

This scenario is illustrative only and uses generic parties. A Southeast Asian technology group with operations across several ASEAN markets wants US valuation benchmarks but a strong Asian shareholder base. Its advisers project a market capitalisation comfortably above S$2 billion and believe it meets Nasdaq Global Select Market standards.

Under the GLB route, it prepares a single US registration statement with the Singapore wrapper, appoints an accredited issue manager and sizes a Singapore tranche at the higher of 15% of the global deal or S$75 million. Within that, it reserves the required retail broker tranche. Testing-the-waters meetings run in the US and with institutional investors in Singapore, consistent with the permitted perimeter.

After listing, its investor relations team mirrors each US filing on SGXNet. Its board also adopts a protocol for any future take-over approach, recognising that the applicable rules depend on its incorporation and listing structure; see our note on the revised Singapore Take-over Code for how the Singapore regime now operates.

Risks and common mistakes

Cross-border angle

An SGX Nasdaq dual listing in Singapore is inherently cross-border. Issuers incorporated outside Singapore must reconcile home-country company law with US securities law and SGX requirements. Groups with operations in Bangladesh, the UAE, China or the UK should check foreign exchange controls, outbound listing approvals and any restrictions on foreign shareholding before committing to a timetable.

Tax and holding structure also matter. A pre-IPO reorganisation to create a suitable listing vehicle can trigger stamp duty, capital gains or withholding issues across several jurisdictions. Our tax structuring team coordinates that analysis with local advisers.

What to do now: a checklist

• Confirm market capitalisation and Nasdaq Global Select Market financial standards with your bankers.
• Map governance, takeover and shareholder-protection rules for your incorporation and listing structure.
• Appoint an accredited issue manager and two authorised representatives early.
• Design the Singapore tranche and retail broker tranche with CDP settlement in mind.
• Agree a cross-border publicity protocol before any testing-the-waters meeting.
• Build an SGXNet disclosure process that mirrors every US filing promptly.
