Facts & Figures

ESG Data Reporting Scope and Notation Guidelines

  • The scope of data encompasses the entire ESG performance of SK bioscience’s domestic worksites (Headquarters, R&D Center, Andong L HOUSE). We have included data on a consolidated basis for those limited ESG activities of our subsidiaries IDT Biologika and TEW Service, which are included in our consolidated financial statements since 2024.
  • The level of reporting varies depending on the availability of information and operational status, and where consolidated basis data is included, the indicators have been noted in a separate footnote.
  • Quantitative data are presented as whole numbers. For figures below 10, values are displayed to the first decimal place. However, exceptions are applied in certain cases to ensure clarity and accuracy of information.
  • When converting euros to Korean won, the average exchange rate from October 1 to December 31 (1 EUR = KRW 1,489.10) was applied.
