Hong Kong, 11 June 2026—In accordance with Rule 22 of the Hong Kong Code on Takeovers and Mergers, Morgan Stanley Capital Services LLC (MSCS), a Class (5) associate of the offeror in the ongoing privatisation of ENN Energy Holdings Limited (ENN Energy), reported a series of derivative transactions referencing the company’s shares.

On 10 June 2026, MSCS executed four unsolicited client-facilitation trades linked to a total of 1,500 ENN Energy shares:

• Purchases – 279 shares (maturity: 4 May 2028) at a reference price of $51.1934, for an aggregate $0.01 million. – 1,221 shares (maturity: 2 September 2027) at a reference price of $51.1933, for an aggregate $0.06 million.

• Sales – 279 shares (maturity: 4 May 2028) at a reference price of $51.1934, for proceeds of $0.01 million. – 1,221 shares (maturity: 2 September 2027) at a reference price of $51.1933, for proceeds of $0.06 million.

Because the purchase and sale volumes and prices matched exactly, MSCS ended the day with a resultant balance of zero in ENN Energy-related derivatives. All dealings were undertaken for the firm’s own account.

The disclosure forms part of transparency requirements tied to ENN Energy’s proposed privatisation by way of a scheme of arrangement. MSCS is ultimately owned by Morgan Stanley.
