How this market cap is arrived at
| Shares outstanding | 4,626,650,861 |
| Basis | sum of separately listed lines |
| As of | 2026-06-30 |
| Source | CATL 2026 Semi-Annual Report (cninfo), share-change table |
| A shares | 4,408,350,561 × 368.5 CNY (300750.SZ) |
| H shares | 218,300,300 × 616.5 HKD (3750.HK) |

A/H spread is extreme - H shares trade far above A shares: on 29 Aug 2026 3750.HK was HKD616.50 (~CNY566) against CNY368.50 for 300750.SZ, a ~54% premium. 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.
Share counts move on a filing cadence, prices move continuously — so this figure is exact only as of the two dates above, and we publish both rather than a single undated number. This company is quoted here through a depositary receipt (CYATY), where one receipt represents 0.25 ordinary shares; the price is put on an ordinary-share basis before it meets the share count.
