Hong Kong, 23 March 2026—ENN Natural Gas Co., Ltd. disclosed dealings in its A shares under Rule 22 of the Hong Kong Code on Takeovers and Mergers, linked to the company’s proposed privatisation via a scheme of arrangement.

On 20 March 2026, Morgan Stanley Capital Services LLC—classified as a Class (5) associate connected with the offeror—executed two offsetting derivative transactions for its own account: • Purchase: 100 A shares through “other types of products” categorised as unsolicited client facilitation, with a reference price of RMB 22.48 per share. Total consideration reached RMB 2,248.00. • Sale: A matching sale of 100 A shares in an identical product, also at RMB 22.48 per share and for RMB 2,248.00.

Both positions are linked to contracts maturing on 31 August 2027, leaving Morgan Stanley Capital Services with a resultant net balance of zero shares. The entity is wholly owned by Morgan Stanley.

The filing underscores ongoing compliance requirements as ENN Natural Gas progresses through its planned privatisation scheme. No additional share accumulations or disposals by Morgan Stanley Capital Services were reported in this disclosure.
