AAC observes a “Quiet Period” that begins one calendar month prior to the announcements of its quarterly, interim results, and two calendar months prior to the year-end financial results to avoid the potential for selective disclosure or its perception of doing so. In order to act in compliance with the relevant legal requirements, and at the same time take into consideration the effective communication and to maintain strong connection with the capital market, during the Quiet Periods, IR will control the attendance of meetings, engagement in telephone conversations with shareholders and investors, and participation in media’s activities upon requests. Moreover, the contents of such communications are limited to information already released or discussed while any other sensitive topics such as current operational data, to-be-announced financial results, potential inside information will not be discussed.

Before attending shareholder and investor meetings, engaging in telephone conversations and participating in media’s activities, IR has to submit written communication scopes/directions to EVP and CFO, and obtain their prior consent. The communication scopes/directions should not involve any inside information, nor should it be beyond the scope of the Company's disclosures and announcements. Following the relevant investor activities, written briefings have to be submitted to EVP and CFO in a timely manner.

IR will keep a proper written record of each investor relations activity.

Press releases and presentation materials published by IR have to be simultaneously published on the Company's website. If inside information or other material contents are involved, they must be simultaneously published on HKEx's and the Company's websites in accordance with the requirements of the Listing Rules of HKEx.
