Counsel: Consider the pitfalls before relisting in Hong Kong


Chinese companies taken private in the US may consider relisting in Hong Kong as an attractive option, but beware the pitfalls, legal experts involved in the recent WuXi Biologics’ relisting in Hong Kong have warned.


WuXi Biologics recently completed its US$510 million global offering and initial public offering (IPO) on the Main Board of the Stock Exchange of Hong Kong, marking the second Chinese company to relist in Hong Kong after going private in the US.

Compared with re-listing in mainland China, one of the major attractions of Hong Kong is the certainty on timing and procedural transparency, Paloma Wang, Hong Kong capital markets partner at Shearman & Sterling, told China Business Law Journal.

“The long waiting period for A-share IPOs is often a big put-off for many companies, while the HKEX [The Stock Exchange of Hong Kong] vetting process is more predictable and manageable,” she said. “Hong Kong as a global financial centre still appeals to international investors, particularly for companies with a global reach, such as WuXi Biologics.”

WuXi Biologics, a Shanghai-based company, is an open-access biologics technology platform offering end-to-end solutions for interested parties to develop biologics from conception of an idea through to manufacturing.

Another advantage of listing in Hong Kong is related to management of US tax issues. Colin Law, the head of Greater China and Asia Capital Markets Group Team Leader at Shearman & Sterling in Hong Kong said that in preparation for an A-share listing, an issuer should have its existing offshore holding structure removed, especially when the variable interest entity (VIE) structure is involved. “More often than not, this will result in significant US tax implications, in the form of capital gains tax,” he added. “The implications can sometimes be better managed with a Hong Kong listing, in part through business and corporate restructuring opportunities.”

HKEX also recently started public consultation for a new third board. If adopted, Law said the new board could offer Hong Kong more flexibility and make HKEX a more appealing venue for listing.

However, those who have gone private from the US should also be aware of the challenges when seeking to relist in Hong Kong. Law said it was not uncommon that US-delisted companies needed to battle with class actions. “Companies seeking a relisting in Hong Kong with past, ongoing or potential class actions will be heavily scrutinized,” he said.

Wang said that ownership and control continuity was a basic eligibility requirement (except for mining companies) for Hong Kong listing. “US-listed Chinese companies taken private are typically led by a consortium comprising third-party financial investors and sometimes the management,” she said. “For Hong Kong purposes, there could well be significant changes to ownership and control, which could well have a significant bearing on the listing timetable.”

Legal counsel: In the WuXi Biologics Hong Kong IPO, Shearman & Sterling advised the underwriters on Hong Kong and US law, with the team led by Hong Kong capital market partners Colin Law, Paloma Wang, Matthew Bersani and US tax partner Laurence Crouch.
