Immucell Corp

ImmuCell Corporation, founded in 1982 and a SEC-registered public company since 1987, is an animal health biologics company focused on the development, manufacture, and commercialization of products intended to improve the survivability, health, and long-term performance of neonatal dairy and beef calves. The Company's practical, science-based solutions help prevent calf scours, one of the most prevalent diseases in neonatal calves worldwide that accounts for 30-40% of pre-weaning mortality in many production systems. The Company’s primary product line, First Defense , utilizes hyperimmunized bovine colostrum to provide pathogen-specific antibodies and other bioactive components. First Defense is designed to provide Immediate Immunity through orally delivered antibodies against the principal viral and bacterial causes of neonatal calf diarrhea (scours), including Escherichia coli (E.coli) , bovine coronavirus, and bovine rotavirus. First Defense is administered at, or soon after, birth in multiple formats, including single-dose boluses, gel formulations delivered by syringe, and multi-dose powder configurations. In the United States, First Defense products are regulated as veterinary biologics by the U.S. Department of Agriculture’s Center for Veterinary Biologics under the Virus-Serum-Toxin Act. In Canada, products are regulated by the Canadian Food Inspection Agency and in other countries, the products are regulated by similar agencies. Certain product formats are marketed as feed supplements regulated by the U.S. Food and Drug Administration under the Federal Food, Drug, and Cosmetic Act. The Company’s manufacturing processes include proprietary vaccine development, dairy herd hyperimmunization management, colostrum sourcing and qualification, antibody concentration and purification processes, blending, fill-finish operations, and final product testing and release. The Company uses third parties to manufacture certain product formats. Products are marketed through the Company’s commercial sales organization in collaboration with a network of international, national and regional animal health distributors.

We grew our manufacturing capacity from approximately 3 million manufactured units during the year ended December 31, 2023 to 4.1 million manufactured units during the year ended December 31, 2024, and 4.6 million manufactured units during the year ended December 31, 2025. Our current business strategy calls for us to further increase our manufacturing capacity in the future.

We grew product sales by 4.3% during the year ended December 31, 2025 compared to the year ended December 31, 2024, and improved gross margin from 30% to 41% of product sales, including a non-cash write off of certain inventories equal to approximately 2.4% of full-year product sales.

In December 2025, we announced our strategy to focus on First Defense and paused further investment in manufacturing Re-Tain , to allow us to focus on the scours market opportunity. Re-Tain , an innovative new treatment for subclinical mastitis, was a product development initiative that the Company had pursued for some time. As a result of this decision, we recognized a $2.7 million non-cash impairment charge related to property, plant and equipment.
