INSIDE INFORMATION

1. DELAY IN PUBLICATION OF THE 2020 ANNUAL RESULTS AND POSSIBLE DELAY IN DESPATCH OF THE ANNUAL REPORT;
2. 1. POSTPONEMENT OF BOARD MEETING;

AND

(3) SUSPENSION OF TRADING

This announcement is made by Hainan Meilan International Airport Company Limited (the "Company", together with its subsidiaries, the "Group") pursuant to Rules 13.09(2)(a) and 13.49(3)(i) of the Rules Governing the Listing of Securities (the "Listing Rules") on The Stock Exchange of Hong Kong Limited (the "Stock Exchange") and the Inside Information Provisions under Part XIVA of the Securities and Futures Ordinance (Chapter 571 of the Laws of Hong Kong).

DELAY IN PUBLICATION OF THE 2020 ANNUAL RESULTS ANNOUNCEMENT AND POSSIBLE DELAY IN DESPATCH OF THE ANNUAL REPORT

The Company is unable to publish the consolidated financial statements of the Group for the year ended 31 December 2020 (the "Annual Results") by 31 March 2021 and despatch of the annual report for the year ended 31 December 2020 (the"Annual Report") may also be delayed as the auditor is still auditing the information provided by the Company so as to clarify the management accounts, thus to complete the audit procedures. The delay in publication of the Annual Results will constitute non-compliance with Rule 13.49(1) of the Listing Rules and the possible delay in the despatch of the Annual Report, if materialised, will constitute non-compliance with Rule 13.46(2)(a) of the Listing Rules. The Company will use its best endeavours to publish the Annual Results as soon as practicable and will make further announcement as and when appropriate, to inform the shareholders of the Company (the "Shareholders") regarding the date of publication of the Annual Results. The Company will also use its best endeavors to despatch the Annual Report to the Shareholders in accordance with the Listing Rules.

The board of directors (the "Board") of the Company hereby states that the operations of the Group are not affected by the abovementioned delays.

POSTPONEMENT OF BOARD MEETING

As disclosed in the announcement of the Company dated 22 March 2021, the meeting of the Board (the "Board Meeting") was originally determined to be held on 31 March 2021 to consider and, if thought fit, approve, among others, the announcement in relation to the Annual Results for publication. As the auditor has not completed the audit of the Annual Results as at the date of this announcement, the Board Meeting will be postponed. The Company will publish further announcement(s) in due course to inform the Shareholders of the latest information, if any, and the date of the Board Meeting to be held for approval of the announcement in relation to the Annual Results for publication.

NON-PUBLICATION OF MANAGEMENT ACCOUNTS

Rule 13.49(3) of the Listing Rules provides that when an issuer is unable to publish its preliminary results, it must announce its results based on the financial results which have yet to be agreed with the auditor (so far as the information is available). The Board has, after due and careful consideration, decided that it would not be appropriate for the Company to publish the unaudited management accounts of the Group for the year ended 31 December 2020 (the "Management Accounts") at this stage having considered that as the finalisation of the Management Accounts and the completion of the audit work are being carried out at the same time, there may be significant adjustments on the Management Accounts. Accordingly, the Management Accounts, if published, may not be a true and fair reflection of the financial performance and position of the Group which may be misleading and confusing to the Shareholders, potential investors and other stakeholders of the Company.

SUSPENSION OF TRADING

At the request of the Company, trading in the H shares (the "H Shares") of the Company on the Stock Exchange will be suspended from 9:00 a.m. on 1 April 2021 pending the publication of the Annual Results. Pursuant to Rule 13.50 of the Listing Rules, the Stock Exchange will normally require suspension of trading in an issuer's securities if an issuer fails to publish periodic financial information in accordance with the Listing Rules, and the suspension will normally remain in force until the issuer publishes an announcement containing the requisite financial information. Accordingly, trading in the H Shares on the Stock Exchange is currently expected to remain suspended after the abovementioned date until the publication of the announcement in relation to the Annual Results by the Company.
