Celia Pheasant, Secretary:

Enclosed is a Notice of Change in Interests of Substantial Shareholder under Section 671B dated 06 November 2018. Please note that a copy of this report has been sent to the Australian Stock Exchange.

The Capital Group Companies, Inc. (“CGC”) is the parent company of Capital Research and Management Company (“CRMC”). CRMC is a U.S.-based investment management company that manages the American Funds family of mutual funds. CRMC manages equity assets for various investment companies through three divisions, Capital Research Global Investors, Capital International Investors and Capital World Investors. CRMC in turn is the parent company of Capital Group International, Inc. (“CGII”), which in turn is the parent company of five investment management companies (“CGII management companies”): Capital Guardian Trust Company, Capital International, Inc., Capital International Limited, Capital International Sàrl and Capital International K.K. The CGII management companies primarily serve as investment managers to institutional clients.

Neither CGC nor any of its affiliates own shares of Megaport Ltd for its own account. Rather, the shares reported on Form 604 are owned by accounts under the discretionary investment management of one or more of the investment management companies that make up CGC.

For the purpose of this Notice, an outstanding share balance of 118,187,230 shares was used to calculate the percentage of holdings. We believe this outstanding share balance is correct; however, if this number is not accurate, please contact us as soon as possible so we may make the necessary revisions.
