China National Building Material Company Limited (CNBM) filed its Monthly Return for Equity Issuer for the period ended 31 July 2026, confirming a stable share-capital structure throughout the month.

Total authorised and registered share capital remained at 7.59 billion shares with RMB 1 par value each. This comprises: • H-shares: 3.72 billion • Domestic shares: 3.88 billion

Issued capital mirrored the authorised amounts, with 3.72 billion H-shares and 3.88 billion domestic shares outstanding. The company held no treasury shares, and there were no increases or decreases in any share class during July.

CNBM verified compliance with the Hong Kong Main Board’s minimum 25 % public-float requirement for its H-shares.

The filing also noted that the group has no outstanding share options, warrants, convertible securities, or other commitments that could dilute existing shareholders.

The return was submitted on 3 August 2026 by Joint Company Secretary Chung Ming Fai.
