On 2 June 2026, Xi’an Haitian Antenna Technologies Co., Ltd. (“Haitian Antenna”) released its Circular and Notice of Annual General Meeting in both English and Chinese. The documents are now accessible on the HKEXnews website (www.hkexnews.hk) and the company’s site (www.xaht.com).

Key points:

• Transition to paperless regime – In line with Rule 16.04A of the GEM Listing Rules, the company will distribute all future corporate communications—annual and interim reports, meeting notices, circulars, proxy forms and other shareholder materials—exclusively via its website and HKEXnews, replacing printed mailings. – Shareholders must regularly check these websites to stay informed of new publications.

• Shareholder actions required – Investors holding H-shares through banks, brokers, custodians, nominees or HKSCC Nominees Limited should provide their email addresses to those intermediaries to ensure timely receipt of electronic notifications. – Non-registered shareholders preferring printed copies can submit a completed reply form to Computershare Hong Kong Investor Services Limited (17M Floor, Hopewell Centre, 183 Queen’s Road East, Wan Chai, Hong Kong) or email xianhaitian.ecom@computershare.com.hk. Printed copies will be supplied free of charge upon request.

• Compliance measures – The initiative aligns the company with HKEX’s expanded paperless listing framework, effective since 31 December 2023, aimed at enhancing disclosure efficiency and reducing environmental impact.

Chairman Xiao Bing signed the notice on behalf of the Board, confirming the company’s commitment to streamlined, eco-friendly communication with its shareholders.
