Daesung Microbiological Labs was founded in 1968 and listed on KOSDAQ in 2000 as a veterinary vaccine and pharmaceutical specialist.
The company produces and sells more than 150 types of veterinary medicines including vaccines, antibiotics, dewormers, nutritional supplements, antipyretic and anti-inflammatory agents, immune boosters, and disinfectants, with the sustained-release PPS injection among its key products.
Korea's animal pharmaceutical industry is heavily influenced by livestock population trends and disease outbreaks, and it remains a fragmented, competitive market with many manufacturers and importers.
Domestic competitors include listed animal-health companies such as Choong Ang Vaccine Laboratories, Eagle Vet, Komipharm, and CTC Bio.
On March 10, 2026, Insilico signed an agreement to acquire a 38.6% stake (1,466,740 shares) in Daesung Microbiological Labs for 11,000 won per share, totaling 16.1 billion won, becoming the controlling shareholder.
This price reportedly reflected a control premium of about 1.74 times the market price at the time of the deal. The acquisition was led by Insilico CEO Choi Seung-hoon, a KAIST-trained biophysical chemist who previously researched molecular modeling and AI-based materials design at Samsung SDI.
Alongside the acquisition, Insilico brought in new board members including Dr. Shin Jae-min, a former U.S.
National Institutes of Health researcher, former Seoul National University professor Choi Yoon-jae from the Department of Agricultural Biotechnology, and professor Kang Sang-ki from Seoul National University's International Graduate School of Agricultural Technology, aiming to strengthen R&D capabilities.
