On 28 May 2026, UBS AG—an exempt principal trader connected with ENN Natural Gas Co. Ltd—filed a disclosure under Rule 22 of the Hong Kong Code on Takeovers and Mergers in relation to the company’s pending privatisation by way of scheme of arrangement.

UBS AG executed hedging transactions in ENN Natural Gas A shares generated by wholly unsolicited client-driven orders. The bank purchased 223,600 shares for RMB4.34 million and sold 256,300 shares for RMB4.97 million, producing a net sale of 32,700 shares and a net cash inflow of roughly RMB0.63 million.

The transactions were carried out for UBS AG’s own account as part of Delta 1 and other equity-related product hedging. UBS AG is ultimately owned by UBS Group AG.
