Dongfang Electric Corporation Limited submitted its Monthly Return for Equity Issuers for the period ended 30 June 2026, confirming that the company’s share structure and public-float status remained stable throughout the month.

Total registered share capital stood unchanged at 3.46 billion shares with a par value of RMB 1 each. The breakdown is as follows: • H-shares: 408.00 million on the Hong Kong Stock Exchange (HKEX) • A-shares: 3.05 billion on the Shanghai Stock Exchange

No new shares were issued, repurchased, or cancelled during June. Consequently, the numbers of issued shares and treasury shares for both H-shares and A-shares were unchanged at 408.00 million and 3.05 billion respectively, with zero treasury shares outstanding.

Dongfang Electric affirmed that its H-share public float met the HKEX minimum requirement for PRC issuers—at least 5% of total issued H-shares—under Main Board Rule 13.32B.

The filing also stated that there were no outstanding share options, warrants, convertible securities, or other arrangements that could lead to future share issuance. All regulatory confirmations required under HKEX Main Board Rule 13.25C were provided.

The report was signed by Joint Company Secretary Mr. Feng Yong and submitted to Hong Kong Exchanges and Clearing Limited on 3 July 2026.
