Hong Kong Exchanges and Clearing Limited (HKEX) may shorten the waiting period for listed companies seeking to spin off and list their subsidiaries, potentially reducing the temporary suspension window from three years to one year after the parent company's initial public offering. On September 21, the exchange launched a market consultation on the second phase of its listing mechanism competitiveness review, publishing a consultation paper that proposes this significant change.
Chen Gang, co-director of the research department at Eddid Financial, told the press that shortening the three-year restriction to one year means companies listed in 2025 and 2026, which already held mature and independently separable businesses at the time of their IPO, could initiate spin-off plans just one year after listing. This would substantially compress the capital operation cycle of "listing the whole entity first, then carving out subsidiaries," reducing time-related costs. Additionally, listed companies could carve out targets with strong independence and sound business logic, attracting investors focused on specific niche sectors.
Hong Kong-listed companies accelerate spin-off timelines
This year has seen multiple Hong Kong-listed companies disclose progress on their spin-off and listing plans. On August 31, Xinyi Glass Holdings Co Ltd announced plans to spin off Xinyi Automobile Glass for listing through a distribution in specie, with the listing application submitted on a confidential basis. On September 4, Genscript Biotech Corp announced its intention to spin off and independently list Probio Biosciences. On September 17, China Travel International Investment Hong Kong Ltd mentioned in its interim results that it plans to spin off its wholly-owned subsidiary, Hong Kong and Macau Cultural Tourism, for listing via distribution in specie.
As early as June, four A+H listed companies disclosed the latest progress on their spin-off plans, having submitted listing application materials for their subsidiaries to the Hong Kong stock exchange. Among these, Midea Group Co Ltd plans to spin off Ander Intelligent, Fosun Pharma intends to carve out Fosun Antengene, Zhejiang Medicine Co Ltd is spinning off Xinma Biopharmaceutical, and Yankuang Energy Group Co Ltd is carving out Wubo Technology. In January, several Hong Kong-listed companies announced they had submitted IPO application materials for their subsidiaries. Baidu Group Inc plans to spin off Kunlun Core, Simecre Pharmaceutical Group intends to spin off Simecre Zaiming, and Sunny Optical Technology Group Co Ltd is carving out Sunny Intelligent Driving.
According to Chen Gang, the recent uptick in spin-off listings correlates with companies proactively seeking value release. In recent years, some listed companies have incubated high-growth, highly independent business units. Spinning off subsidiaries for independent listings broadens their financing channels, which can in turn support the parent company and enhance the subsidiary's valuation.
Looking back historically, numerous property developers have carved out their property management services for listing. Sunac Services, Country Garden Services, and Yuexiu Services were all spun off from real estate groups. Internet platform companies have likewise capitalized on their business lines. JD.com Inc spun off JD Health, JD Logistics, and JD Industrial. Tencent Holdings Ltd successively carved out China Literature, Yixin Group, and Tencent Music Entertainment Group. Biotech, consumer, mobility, and leasing sectors have also seen parent companies spinning off their subsidiaries.
It is worth noting that spin-off listings are not a universal solution. While they can release asset value, attention must be paid to related-party transactions, valuation reasonableness, and long-term earnings quality.
Relaxing spin-off requirements
HKEX explained that the temporary suspension period was originally designed to safeguard investors' investment decisions made based on the business portfolio at the time of the parent company's listing. However, considering changes in issuers' business expansion, diversification, and financing needs after listing, the mandatory three-year suspension period may be overly stringent. A one-year period aligns with existing safeguards preventing fundamental changes to an issuer's principal business within 12 months of listing.
In recent years, HKEX has been working to unblock listings and revitalize existing resources through listing system reforms and refinements. Yuan Mei, research director at Frost & Sullivan Jieli (Shenzhen) Technology Co Ltd, noted: "Shortening the suspension period allows more listed companies to spin off and list their businesses more quickly. Some companies queuing for IPOs may no longer fixate on going public directly, but instead pursue capital needs through investment, mergers and acquisitions, or spin-off listings. Greater capital operation activity among existing listed companies helps relieve pressure on the IPO pipeline."
Additionally, the consultation paper proposes simplifying the regulatory process for spin-offs by introducing a self-assessment mechanism for eligible issuers, eliminating the need for exchange approval. Currently, all spin-off listings require prior HKEX approval. The consultation paper also notes that as of June 30, 2026, there are nearly 500 listed issuers with a market capitalization of at least HK$10 billion and revenue of at least HK$1 billion, accounting for nearly 20% of all issuers on the Hong Kong market—all of which are main board companies. If these issuers pursue spin-off listings, they would qualify for the self-assessment pathway provided their remaining businesses account for more than 50% of the issuer group's total revenue and assets, without having to submit spin-off proposals for HKEX approval.
Huang Lichong, president of Huisheng International Capital Co Ltd, observed that for sectors where subsidiary businesses have matured and are primarily constrained by the waiting period, shortening the suspension period could advance financing arrangements. However, for sectors where financial metrics or commercialization readiness remain incomplete, the one-year threshold cannot close those gaps. Listed companies need to consider whether institutional investors understand the subsidiary's business, whether suitable comparable companies exist within the industry, and the subsidiary's liquidity and refinancing capabilities after listing.
