Hong Kong, 10 June 2026 — In connection with the proposed privatisation of ENN Energy Holdings Limited by way of a scheme of arrangement, the Executive received a Rule 22 disclosure detailing securities dealings by a party connected to the offeror.

On 9 June 2026, Morgan Stanley & Co., International plc, identified as a Class (5) associate of the offeror, executed Delta 1 hedging transactions arising from wholly unsolicited client-driven orders:

• Purchases: 30,500 ordinary shares for a total consideration of $1.57 million at prices ranging from $50.238 to $51.700 per share. • Sales: 1,900 ordinary shares for $0.10 million at prices between $50.238 and $52.200 per share.

The net result was a purchase of 28,600 shares valued at approximately $1.47 million. All dealings were carried out on Morgan Stanley & Co., International plc’s own account. The firm is ultimately owned by Morgan Stanley.

These disclosures fulfil Hong Kong Takeovers Code requirements during ENN Energy’s ongoing privatisation process.
