5Wastewater generated at the Company's operations in China is discharged entirely into the centralized sewage network of the industrial park after pretreatment and compliance with
discharge standards. As there is no individual external discharge outlet the exact total volume of wastewater discharge cannot be precisely measured. The wastewater discharge volume for
the China operations is calculated using a conversion factor of 0.8 multiplied by the total water intake and this method has also been applied to revise the 2024 wastewater discharge data
accordingly. 652025 Sustainability Report

Appendix 2 Index to 1Data on energy conversion into standard coal is derived from the General Rules for Calculation of the Comprehensive Energy Consumption (GB/T 2589-2020). The Company’s direct energy
Guidelines of SSE consumption mainly comes from gasoline and natural gas while indirect energy consumption mainly comes from purchased electricity.Appendix 3 Index to PSCI 2In this year the definition of water consumption has been revised to be calculated as water intake minus wastewater discharge reflecting the Company’s overall impact on the availability of
Principles downstream water resources.
3Data only includes Vernalis a wholly-owned overseas subsidiary of the Company.
4Scope 1 GHG emissions refer to direct GHG emissions generated from the consumption of fossil fuels such as gasoline and natural gas during the operation of HitGen’s own equipment.
5Sources of 2025 emission factors: the average Sichuan power sector CO2 emission factor for 2023 which is 0.1564 kg CO2/kWh as specified in the Announcement on Issuing the 2023 Power
Sector CO2 Emission Factors issued by the Ministry of Ecology and Environment of the People's Republic of China; the GHG emission factor for electricity in the UK used in this report adopts
the grid average emission factor from UK Government GHG Conversion Factors for Company Reporting 2025 V1.0 with a total CO2 equivalent factor of 0.1770 kg CO2e/kWh. The decrease in
Scope 2 GHG emissions in 2025 is mainly attributable to the adjustment of the CO2 emission factor for electricity consumed at the Company’s operating sites in China from the national grid
average emission factor to the corresponding provincial grid average emission factor. Source of 2024 emission factor: the national average power sector CO2 emission factor for 2022 which
is 0.5366 kg CO2/kWh as specified in the Announcement on Issuing the 2022 Power Sector CO2 Emission Factors issued by the Ministry of Ecology and Environment of the People's Republic of
