## TL;DR

Samsung Biologics is the world's largest biologics CDMO by capacity, and opened a dedicated ADC conjugation facility in 2025.

## Summary

Samsung Biologics, based in Incheon and listed as 207940.KS, is the world's largest biologics CDMO by capacity and opened a dedicated antibody-drug conjugate conjugation facility in 2025. It runs mammalian cell culture at unprecedented scale at its Songdo Plant 5, adds ADC conjugation and fill-finish, and announced the spin-off of Samsung Bioepis in 2025. OnCo links it to ADC bioconjugation manufacturing, antibody manufacturing and sterile fill-finish. Whether Korean capacity becomes the main beneficiary as sponsors diversify ADC manufacturing away from China is the open question. The ADC manufacturing page carries the wider picture.
