On February 26, 2026, the Hong Kong Exchanges and Clearing Limited ("HKEX") initiated a series of market rehearsals for its impending backbone network upgrade, scheduled for the third quarter of 2026. These rehearsals are intended to validate system connectivity, test operational processes, and identify potential issues prior to the network cutover. The upgrade is a crucial element of HKEX's technology lifecycle management plan, aimed at enhancing the stability, reliability, and resilience of its critical market systems.

In line with the backbone network upgrade, the Secure File Transfer Protocol ("SFTP") channel used by Relevant Regulated Intermediaries ("RRIs") for submitting the BCAN-CID Mapping File and Reporting Forms to the Stock Exchange of Hong Kong Limited will be subject to verification during the rehearsals. Participation in these rehearsals enables RRIs to assess and confirm the operational readiness of their file submission processes under the upgraded network environment, ensuring ongoing compliance with regulatory requirements.

The rehearsals are mandatory for Exchange Participants ("EPs") and China Connect Exchange Participants, with all other RRIs strongly encouraged to participate. Detailed information about the rehearsals' schedule and logistical arrangements will be provided in due course. Intermediaries are advised to refer to HKEX’s Circular dated 26 February 2026 for further guidance and to remain vigilant for subsequent communications from the Securities and Futures Commission ("SFC") and HKEX regarding this initiative.
