Coastal Greenland Limited has issued a shareholder notice outlining four alternatives for receiving future corporate communications, in accordance with Hong Kong Listing Rules 2.07A and 2.07B and the company’s bye-laws.

1. Shareholders may: • access documents electronically via www.coastal.com.cn and receive a publication notice; • request printed English versions only; • request printed Chinese versions only; or • request both printed English and Chinese versions.

2. Action required: New shareholders should complete and return the enclosed request form to the Hong Kong branch share registrar, Tricor Investor Services Limited (17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong).

3. Response deadline: If no completed form is received by 28 August 2026 (28 days from the letter date of 31 July 2026), shareholders will be deemed to have consented to the online-only method. A notification letter or e-mail will then accompany each online release.

4. Flexibility: Elections can be changed at any time by written notice or a new request form. Printed copies will be supplied free of charge upon request if electronic access proves difficult.
