Hong Kong witnessed a rare delay of an initial public offering (IPO) debut on Wednesday, the first in more than eight months, triggered by a regulatory requirement for additional client information, according to people familiar with the matter.On Tuesday night, just before its scheduled listing on Wednesday, DKE Holding Company postponed its IPO ceremony after it failed to provide investors with an offer price and results of its bookbuilding.The maker of e-paper display modules said more time was needed to finalise the exchange announcement and obtain clearances from regulators, with the event now postponed to Thursday, according to a filing issued on Tuesday night.A brokerage firm submitted share purchase documents via Hong Kong Exchanges and Clearing’s (HKEX’s) FINI digital IPO platform, but was asked by the regulatory authority to provide additional client information, resulting in the delay, according to a source who requested anonymity as they were not authorised to speak publicly on the matter.The brokerage firm was probably not familiar with the process, the source added.HKEX chairman Carlson Tong Ka-shing speaking at a ceremony to mark the 26th anniversary of Hong Kong Exchanges and Clearing, on June 26, 2026.
