Hennessy Research Associates

What Hennessy Research Associates does

Hennessy Research Associates (HRA) is a Kansas-based veterinary contract research and vaccine manufacturing organization that serves animal health pharmaceutical and biotechnology companies. Founded in 2001 and headquartered in Lenexa, Kansas, the company operates two integrated service lines: veterinary contract research supporting product development, clinical studies, and regulatory submissions, and contract manufacturing of veterinary biologics and vaccines across multiple animal species. HRA functions as a specialized B2B CMO/CRO, with revenue derived from quote-based professional services engagements with sponsors outsourcing specialized veterinary research and multi-species vaccine production capacity.

HRA's value proposition centers on multi-species manufacturing expertise, scientific depth in veterinary product development, and operational responsiveness to sponsors with capacity constraints. The company targets animal health business units seeking outsourced research and biologics manufacturing, addressing the broader industry trend toward outsourcing and rising demand for veterinary vaccines. Operating with 51-100 employees, HRA has built a 24-year operating history in a heavily regulated niche requiring USDA and FDA compliance, representing a meaningful barrier to new entrants.

In August 2025, Kemin Industries acquired HRA to strengthen its position in the US and global animal health market. Post-acquisition, HRA's team, services, and customer commitments are maintained, with customer service operations integrated into Kemin's shared service function. The acquisition repositions HRA as a platform within Kemin's broader animal health strategy, with potential for expanded geographic reach and cross-selling into Kemin's global ingredient and health product customer base.
