Cronex was founded in May 2012 and listed on KONEX in 2015 as a small-cap biotech. Its business is structured around three pillars: (1) non-clinical CRO services, (2) biological specimen supply (SPF mini-pig breeding and sales), and (3) bio-materials and xenotransplantation R&D.
According to a 2020 Ebest Investment Securities research note, the non-clinical CRO segment accounts for the largest share of revenue, while the biological specimen segment contributed roughly 40%.
The CRO business outsources efficacy and safety testing using animal models for drug and medical device prototypes, serving clients such as LG Electronics, Classys, Osstem Implant, Seoul National University, and Yonsei University's Dental College.
On the production side, the company operates a Ministry of Food and Drug Safety-designated Good Laboratory Practice (GLP) facility in Cheongju, Chungbuk, certified in July 2019, and opened an additional non-clinical testing center in Suwon in 2022 covering cosmetics, pharmaceuticals, and health functional foods.
Key competitors include Optipharm (153710) and MGenPlus (032790), but Cronex is assessed as the only company in Korea with an ISO-certified large-scale production facility for bio-materials and xenotransplantation-grade animals.
The Jeju native black pig, the company's core biological asset, is a domestic endemic breed free from the Nagoya Protocol's access and benefit-sharing requirements, providing both pricing leverage and supply-chain independence.
In xenotransplantation, the company employs CRISPR-Cas12 gene editing — licensed from the Broad Institute — to simultaneously remove three immune-rejection genes (α-GaL, CMAH, β4GALNT2) from mini-pigs, achieving mass production that is a first in Korea and second in the world.
Jeju province has granted the company a 20-year free land lease on a 9,600㎡ site and signed an exclusive MOU with Jeju National University and the Jeju Livestock Promotion Institute, securing a strong regional partnership framework.
