The Walkers team, led by partners Andrew Barker and Mark Cummings, and supported by senior associates Beverly Lui and Flora Lo, and associate Samantha Currie, advised on all the Cayman Islands legal aspect of the transaction. We worked closely with InSilico Medicine's lead counsel Davis Polk & Wardwell to ensure seamless execution across multiple jurisdictions.
This listing underscores the development trends in emerging sectors such as AI and biotechnology. It enables InSilico Medicine to advance its clinical pipeline through its proprietary Pharm.ai platform and to invest further in cutting-edge technologies, including generative AI and automated laboratories. InSilico Medicine raised HK$2.277 billion in this IPO, achieving the largest biotech IPO in Hong Kong this year, as in the size of fundraising.
Andrew Barker commented, "We are proud to have provided ongoing support to InSilico Medicine, particularly in helping it reach this milestone transaction. It highlights investor confidence in emerging sectors and demonstrates our ability to deliver strategic, multi-jurisdictional legal solutions that empower clients to scale globally."
Mark Cummings added, "Our cross-border Corporate team thrives on guiding clients through complex corporate transactions. This successful listing reinforces Walkers’ commitment to delivering innovative, round-the-clock legal advice that helps businesses navigate uncharted waters and seize opportunities in dynamic markets."
Congratulations to everyone involved in this transaction.
