28 May 2026—The Executive of the Hong Kong Takeovers and Mergers Panel has received a Rule 22 disclosure showing that Morgan Stanley Capital Services LLC, a Class (5) associate connected with the offeror in the proposed privatisation of ENN Natural Gas Co., Ltd., carried out four offsetting derivative transactions in the company’s A shares on 27 May 2026.

Two unsolicited client-facilitation purchases were executed: • 100 shares tied to derivatives maturing 31 August 2027 at RMB 19.2580 each, totalling RMB 1,925.80. • 100 shares tied to derivatives maturing 31 March 2027 at RMB 19.2300 each, totalling RMB 1,923.00.

On the same day, the firm completed two matching sales of equal size, price and maturity, resulting in identical cash amounts received. Consequently, Morgan Stanley Capital Services ended the trading day with a zero net derivative position in ENN Natural Gas.

All dealings were conducted for the firm’s own account. Morgan Stanley Capital Services LLC is ultimately owned by Morgan Stanley.
