Applying one price to all 4.627bn shares is badly wrong in either direction; value 4,408,350,561 A shares at the A price and 218,300,300 H shares at the H price. 62,385,000 new H shares were placed on 30 Apr 2026 at HKD628.20 under a general mandate. A shares in Shenzhen and H shares in Hong Kong are priced separately; the H line trades at a marked premium."
