WELCOME TO MASTER AD PUBLIC COMPANY LIMITED (MACO) INVESTOR RELATIONS

The Company places a high priority on investors’ access to the Company. The Investor Relations (IR) Department is responsible for communications between the Company and investors, including shareholders, analysts and potential investors. The IR Department functions as the channel for two-way communications, the first of which is to publicise the accurate, complete and timely information of the Company, which includes business operations, performance and key events that affect the Company’s performance. The other aspect is to report the investment community’s opinions and suggestions to the Executive Committee and the Board of Directors on a quarterly basis in order to acknowledge (and respond where relevant to) the viewpoints that investors have on the Company.
