IMPLICATIONS UNDER THE LISTING RULES

Each of the grants of Restricted Shares to Grantees who are connected persons of the Company constitutes a connected transaction of the Company under Chapter 14A of the Listing Rules. Among such Grantees, Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler are Directors of the Company and directors of Melco Resorts, are therefore connected persons of the Company.

Based on the closing price of US$7.56 per ADS as quoted on the Nasdaq Global Select Market on 3 April 2024 and the number of Restricted Shares granted to each of Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler as described in this announcement, one or more applicable percentage ratios is 0.1% or more but each of the applicable percentage ratios is less than 5%. Accordingly, the grant of Restricted Shares to each of Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler described in this announcement above is subject to the reporting and announcement requirements but exempt from the independent shareholders’ approval requirements under Chapter 14A of the Listing Rules.

For the grant of Restricted Shares to each of the connected persons of the Company other than Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler, since all of the applicable percentage ratios are less than 0.1% (for Mr. Chung Yuk Man, Clarence and Mr. John William Crawford) and 1% (for all other connected persons, who are connected at the subsidiary level of the Company), respectively, and the grants of Restricted Shares to each of them are on normal commercial terms or better, the grant of Restricted Shares to each of them is fully exempt from the reporting, announcement and independent shareholders’ approval requirements under Chapter 14A of the Listing Rules.

Reasons for and benefits of the grants of Restricted Shares to Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler

The purpose of the aforesaid grants of Restricted Shares to Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler is to incentivise and motivate such Grantees to strive for the future development of the Melco Resorts Group and its businesses.

The Directors (including the Independent Non-executive Directors) consider that the terms of the grants of Restricted Shares by Melco Resorts to Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler are fair and reasonable, that the grants are on normal commercial terms or better (as far as the Company is concerned) and in the ordinary and usual course of business of the Group, and that the grants are in the interests of the Company and its shareholders as a whole.

Grants of the Restricted Shares described in this announcement has been approved by the Melco Resorts Compensation Committee in accordance with the rules of the Melco Resorts Share Incentive Plan, and as applicable, the Renumeration Committee of the Company and the Board (including the Independent Non-executive Directors), except that Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler who have a material interest in the grant of Restricted Shares to each of them, or persons otherwise required to abstain from voting under the Listing Rules, had abstained from voting on the Board resolution in relation to such grant.

The number of Restricted Shares granted to Mr. Ho, Lawrence Yau Lung and Mr. Evan Andrew Winkler is determined with reference to their respective duties and responsibilities at Melco Resorts Group, namely, Mr. Ho, Lawrence Yau Lung as director at the subsidiary level and Mr. Evan Andrew Winkler as the President and director of the boards of Melco Resorts and its subsidiary.

The Melco Resorts Share Incentive Plan is a share scheme that may be funded, in whole or in part, by new Melco Resorts Shares issued by Melco Resorts and/or existing ADSs or Melco Resorts Shares. Accordingly, subject to the determination of Melco Resorts at the time of vesting of the relevant grants, the Restricted Shares granted to the Grantees as described in this announcement above may be satisfied by new Melco Resorts Shares issued by Melco Resorts and/or existing ADSs or Melco Resorts Shares at the time of vesting. Assuming that all of the Restricted Shares granted would be satisfied by new Melco Resorts Shares issued by Melco Resorts upon vesting, Melco Resorts will continue to be a subsidiary of the Company following the issue of the relevant Melco Resorts Shares. The use of existing ADSs purchased on the market to satisfy Restricted Shares granted under the Melco Resorts Share Incentive Plan will not result in a dilution effect on the shareholding of the Company in Melco Resorts. In the case where the Restricted Shares granted would be satisfied in whole or in part by existing ADSs purchased on the market, the dilution effect on the shareholding of the Company in Melco Resorts would be smaller (or none), compared to the case where the Restricted Shares are satisfied by new Melco Resorts Shares issued by Melco Resorts in whole.
