Merck KGaA to Acquire Bio-Techne, Expanding Life Science Portfolio

Merck KGaA (Darmstadt, Germany) agreed on June 25, 2026, to acquire Bio-Techne Corporation (Minneapolis, MN, USA) for US$73 per share in cash, valuing the transaction at approximately US$11.3 billion (EUR 9.9 billion). The companies present the combination as highly complementary and positioned to support customers from discovery and translational research through development, testing, and commercial manufacturing. The proposed transaction has been approved by Bio-Techne’s Board of Directors and the relevant corporate bodies of Merck KGaA, Darmstadt, Germany.

Bio‑Techne would bring a globally recognized catalog of cytokines, growth factors, antibodies, and immunoassay kits, alongside ProteinSimple automated protein detection and analysis instruments. Its RNAscope and related in situ hybridization technologies would expand spatial biology and diagnostics capabilities, while its materials, analytics, and process technologies would enhance support for cell therapy developers. Together, the organizations aim to address increasingly complex next‑generation biology workflows with integrated solutions.
