August 6, 2026, Hong Kong — According to sources close to the Hong Kong Stock Exchange (HKEX), the exchange is planning significant amendments to Chapter 8A of its Listing Rules, proposing stricter ongoing compliance requirements for both new listings and already-listed companies with dual-class share structures (also known as weighted voting rights structures). This move is seen as another important signal, following the Singapore Exchange, that major Asian capital markets are seeking a new balance between founder privileges and investor protection.
Sunset Clauses: From Voluntary to Mandatory
Sources exclusively told BuGu ZhiShi that the core of the HKEX's revision lies in introducing mandatory sunset clauses. Under the preliminary plan, for all listed companies with dual-class share structures, their super-voting rights shares must automatically convert into ordinary shares upon the triggering of specific conditions. These conditions include: the death, incapacity, retirement, or transfer of shares by the founder or core management, or a change in company control.
Unlike current rules, the new regulations will no longer allow listed companies to set their own sunset mechanisms through their articles of association. Instead, a unified standard will be mandatory for all dual-class share companies. When the HKEX first permitted the listing of companies with weighted voting rights in 2018, it only required companies to set voluntary sunset clauses, but in practice, few companies have proactively triggered them. Data shows that as of June 2026, there were 42 listed companies with dual-class share structures on the HKEX, of which only 3 had time-based sunset clauses, with the rest relying mainly on event-based sunsets.
"A mandatory sunset clause is a key step to remedy corporate governance deficiencies," Chen Zhihong, a law professor at the University of Hong Kong, told this newspaper. "The existence of super-voting rights is reasonable in itself, but without an effective exit mechanism, this privilege can be abused, ultimately harming the interests of minority shareholders."
Expansion of Independent Directors' Supervisory Powers
Beyond the sunset clause, the HKEX also plans to strengthen the supervisory function of independent directors in dual-class share companies. According to the draft amendment, independent directors will gain veto power over the exercise of super-voting rights. When independent directors believe a founder's decision may harm the company's overall interests or the rights of minority shareholders, they can suspend the exercise of the relevant super-voting rights and request a re-deliberation by the board.
This clause is interpreted by the market as the HKEX's response to several recent corporate governance controversies. In 2025, the Hong Kong stock market witnessed two high-profile cases: the founder of a dual-class share technology company used super-voting rights to force through a related-party transaction, causing the company's stock price to plummet by 30%; the founder of another biomedical company transferred the company's core patents at a low price to another company under their control without adequate disclosure. Although the Securities and Futures Commission of Hong Kong intervened to investigate afterward, investor losses were irreversible.
"The expansion of independent directors' supervisory powers means founders can no longer act arbitrarily," said Li Weiqiang, president of the Hong Kong Independent Non-Executive Directors Association. "But the key lies in whether independent directors can truly be independent and whether they have sufficient resources and capability to fulfill this duty."
Upgrading Information Disclosure Transparency
Regarding information disclosure, the HKEX plans to require dual-class share companies to disclose the exercise of super-voting rights every six months, including whether the founder used super-voting rights in key decisions, the voting results, and the supervisory opinions of independent directors. Additionally, companies must detail in their annual reports the identity of super-voting rights holders, changes in their shareholding ratio, and any potential conflicts of interest.
This requirement echoes similar regulations introduced by the SEC in 2025. The U.S. Securities and Exchange Commission previously required all dual-class share companies listed in the U.S. to disclose a founder privilege checklist, including details on super-voting rights, private jet usage, and related-party transactions. The HKEX's amendment is seen as the Asian market catching up with global corporate governance standards.
"Transparency is the foundation of investor protection," said Zhang Minhua, convener of the Hong Kong Minority Shareholders' Rights Alliance. "In the past, it was very difficult to know what founders actually did with their super-voting rights. Now, at least there is a monitoring window."
However, some market participants have expressed concerns about the potential impact of the amendments. The Hong Kong Venture Capital and Private Equity Association, in a consultation paper submitted to the HKEX, pointed out that overly strict sunset clauses and monitoring mechanisms could weaken Hong Kong's appeal to innovative enterprises. The association argues that the dual-class share structure is an important tool for technology companies to maintain long-term strategic focus, and excessive regulation could lead companies to choose other markets for listing.
"This is a delicate balance," Lin Wanyi, Chief Regulatory Officer of the HKEX, said at an internal seminar at the end of July. "Our goal is not to abolish the dual-class share structure, but to allow it to develop more healthily. Good corporate governance is not a constraint, but a guarantee for creating long-term corporate value."
Market Reaction and Future Outlook
Following the news, the Hong Kong stock market showed mixed reactions. Shares of some technology companies with dual-class share structures experienced slight declines, as the market worried that founder control might be weakened. However, most analysts believe that in the long run, stricter governance standards will help boost investor confidence and lower risk premiums.
Morgan Stanley stated in a research report that the HKEX's amendments will accelerate the convergence of corporate governance standards across Asia, predicting that more Asian markets will follow suit with similar regulations within the next two years. The report also suggested that mandatory sunset clauses could prompt a group of dual-class share companies to plan for control transition schemes in advance, thereby avoiding future governance vacuums.
The HKEX plans to publish the consultation paper for the amendments in the fourth quarter of 2026 to seek market feedback. The formal rules are expected to take effect in the first quarter of 2027. For dual-class share companies already listed in Hong Kong, the HKEX will grant an 18-month transition period for adjustments.
"This is not just a rule amendment, but a significant upgrade of Hong Kong's corporate governance philosophy as an international financial center," HKEX Group Chief Executive Officer Chen Yiting previously stated in a public forum. "We believe that better governance means a better market, and a better future."
As global capital markets pay increasing attention to corporate governance, the HKEX's amendment may trigger a chain reaction. For investors, this is undoubtedly a positive signal: the balance between founder privileges and investor protection is tilting toward the latter.
