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.
  • When converting euros to Korean won, the average exchange rate from October 1 to December 31 (1 EUR = KRW 1,489.10) was applied.
