Dual Class Shares SGX Singapore: When Founders Keep Control With Fewer Shares
Understand how dual class share structures let SGX-listed founders retain voting control while raising public capital, and the risks minority shareholders take on.
A dual class share structure lists two classes of shares with different voting rights on the same company, typically giving founders or a controlling group multiple votes per share while public shareholders hold single-vote ordinary shares, allowing the company to raise capital publicly without ceding board control.

Key Takeaways
- SGX allowed dual class share (DCS) structures on the Mainboard starting in 2018, a departure from the traditional one-share-one-vote principle that had governed Singapore listings before that.
- A typical DCS structure gives founder or insider shares multiple votes each (commonly up to 10 votes) while ordinary public shares carry one vote each.
- DCS listings on SGX are subject to enhanced safeguards, including sunset clauses that can convert multi-vote shares to ordinary shares upon specified trigger events.
- The structure is designed to attract high-growth, founder-led companies — particularly technology firms — that might otherwise list in markets like the US that have long permitted dual class shares.
- Minority shareholders in a DCS company have proportionally less influence over major decisions than their economic stake would suggest under a standard one-share-one-vote company.

What Is a Dual Class Share Structure?
For most of its history, the Singapore Exchange required listed companies to follow the “one share, one vote” principle: every ordinary share carried equal voting power regardless of who held it. This changed in 2018, when SGX introduced rules permitting dual class share (DCS) structures for new listings on the Mainboard, aligning Singapore more closely with exchanges like Nasdaq and the New York Stock Exchange that have long allowed multiple-vote share classes.
A dual class share structure typically involves two share classes: ordinary shares, usually held by public investors and carrying one vote each, and a separate class of shares — often held by founders, early executives, or strategic backers — carrying multiple votes per share, commonly up to ten votes. This allows a founder who may hold a relatively small economic stake in the company to nonetheless retain effective control over shareholder votes, including the election of directors and approval of major corporate actions.
The policy rationale behind allowing DCS on SGX was largely about competitiveness: high-growth technology and founder-led companies increasingly favoured DCS-friendly markets when choosing where to list, and Singapore risked losing these listings to exchanges like Nasdaq, Hong Kong, or the US markets if it maintained a strict one-share-one-vote requirement. Enabling DCS structures, subject to safeguards, was intended to make SGX a more viable listing venue for founders unwilling to dilute control alongside their economic stake.
How Does a Dual Class Share Structure Work in Singapore?
SGX’s DCS framework includes several safeguards designed to balance the benefits of allowing founder control against the risks to minority shareholders. Multi-vote shares are generally capped at a specified maximum ratio relative to ordinary shares, and companies must meet enhanced corporate governance requirements, such as having a majority-independent board and an independent lead director, to list with a DCS structure.
A key protective mechanism is the sunset clause. This automatically converts multi-vote shares into ordinary one-vote shares upon the occurrence of specified trigger events — for example, if the holder of multi-vote shares ceases to be a director or senior executive of the company, transfers their shares to someone outside a permitted group, or after a fixed number of years from listing. Sunset clauses are intended to prevent multi-vote control from persisting indefinitely or passing to parties who were not part of the original founding vision that justified the enhanced voting rights in the first place.
Certain matters are also typically carved out as requiring approval on a one-share-one-vote basis regardless of the DCS structure, such as variations to the rights attached to different share classes themselves, or delisting decisions, protecting minority shareholders from having their most fundamental interests overridden purely by multi-vote control.
DCS listings remain relatively uncommon on SGX compared to traditional single-class listings, reflecting both the narrower pool of founder-led, high-growth companies choosing SGX as a primary listing venue and the additional governance scrutiny DCS structures attract from investors and analysts.
a Dual Class Share Structure Example
Consider a hypothetical Singapore-founded technology company preparing to list on SGX’s Mainboard. The founder holds 15% of the company’s total economic interest but structures their shareholding as Class B shares carrying 10 votes each, while the remaining 85% of shares sold to the public are Class A ordinary shares carrying one vote each.
Doing the arithmetic, the founder’s 15% economic stake translates into roughly 64% of total voting power (15 × 10 = 150 “votes” out of a combined 235 total votes from 15 Class B and 85 Class A shares, simplified for illustration), giving them effective control over board elections and major resolutions despite holding a minority of the company’s economic value.
The listing prospectus discloses a sunset clause specifying that the founder’s Class B shares will automatically convert to ordinary Class A shares if the founder ceases to serve as an executive director of the company, or after a defined number of years, whichever comes first. A public investor buying Class A shares at listing is, in effect, betting on the founder’s long-term vision and governance quality, accepting reduced voting influence in exchange for participating in the company’s growth alongside continued founder-led execution.
Advantages of a Dual Class Share Structure
- Founder alignment. Multi-vote structures let founders retain strategic control, arguably supporting longer-term decision-making less subject to short-term market pressure.
- Access to high-growth listings. DCS rules make SGX a more viable venue for founder-led technology and growth companies that might otherwise list exclusively overseas.
- Governance safeguards. Sunset clauses and enhanced board independence requirements are specifically designed to limit how long and how broadly multi-vote control can persist.
- Capital access without control dilution. Founders can raise substantial public capital for growth while retaining the ability to execute their strategic vision without ceding board control prematurely.
- Protected minority votes on key matters. Certain fundamental matters, such as share class rights variations, are carved out to still require broader shareholder approval regardless of the DCS structure.
Risks and Limitations
- Reduced minority influence. Public shareholders in a DCS company have proportionally less say over board composition and major decisions than their economic stake would otherwise imply.
- Entrenchment risk. Multi-vote control can, in poorly governed cases, allow underperforming leadership to resist removal even where shareholder value is being eroded.
- Valuation discount debate. Some investors apply a valuation discount to DCS companies to reflect reduced governance influence, which can affect trading multiples relative to single-class peers.
- Complexity for retail investors. Understanding the true voting power behind a DCS structure requires reading prospectus disclosures carefully, which many retail investors skip in favour of headline growth metrics.
- Sunset clause variability. Not all DCS structures have equally robust sunset provisions, so investors need to check the specific trigger events and timeframes in each company’s own structure rather than assuming a standard template applies.
Dual Class Shares vs Single Class (One-Share-One-Vote) Structure
| Aspect | Dual Class Shares | Single Class (Traditional) |
|---|---|---|
| Voting power | Multi-vote shares can exceed economic stake | Voting power matches economic stake exactly |
| Founder control | Can be retained despite significant dilution | Diminishes proportionally as shares are sold |
| Minority shareholder influence | Reduced relative to economic stake | Proportional to economic stake |
| Governance safeguards | Sunset clauses, enhanced board independence required | Standard governance rules apply |
| SGX availability | Allowed on Mainboard since 2018, subject to conditions | Default structure for the vast majority of listings |

The Bottom Line
For Singapore investors, a dual class share structure is not inherently good or bad — it is a trade-off between founder-aligned long-term decision-making and reduced minority voting influence, and the quality of the sunset clause and broader governance framework matters far more than the mere existence of multiple vote classes.
