Contract drug manufacturing (CDMO)
−0.47%CDMO
The CDMO (contract development and manufacturing organization) theme covers Korean companies that develop and manufacture pharmaceuticals, biologics, and related products on behalf of other drug companies, rather than selling their own branded medicines. Korean investors often group these firms together because they share a business model centered on large-scale bioproduction capacity, long-term client contracts, and exposure to the global biopharma outsourcing trend. The theme is also frequently linked to the broader Korean biotech sector, so its share prices tend to move alongside related names.
