Merck Unveils $895 Million Development Project
Merck Animal Health and Kansas Governor Laura Kelly announced an $895 million expansion of Merck’s manufacturing facility in De Soto, Kansas.
The capital expansion includes an $860 million investment in the site’s existing manufacturing facility and a further $35 million investment in its research and development laboratories.
The 200,000-square-foot manufacturing facility project will expand filling and freeze dryer capacity for large molecule veterinary vaccines and biologic products. The expansion will create 2,500 construction jobs. Commercial manufacturing is expected to begin in 2030, creating more than 200 full-time positions.
The investment will continue to drive Merck Animal Health’s innovative research and development of novel parasiticides and therapeutics, reinforcing the company’s dedication to improving animal health and welfare worldwide.
“Our De Soto, Kansas manufacturing facility is strategically located in the heart of the Animal Health Corridor. This region is renowned for its concentration of animal health companies, fostering an unparalleled ecosystem for innovation, collaboration and industry leadership,” said Richard DeLuca, president, Merck Animal Health. Merck is partnering with the state of Kansas on expansion of the existing manufacturing facility. MeV
