Merck KGaA buys Bio-Techne for $11.3 billion in largest deal in a decade

Merck KGaA announced on June 25, 2026, that it had agreed to acquire U.S. biotech firm Bio-Techne for $11.3 billion in cash, its largest deal in over a decade.

The offer of $73 per share represents an enterprise value of about $11.3 billion and a 24–36% premium to Bio-Techne's recent trading price.

Merck aims to strengthen its life sciences business by adding Bio-Techne’s research reagents, proteins, antibodies, instruments, and multiomics offerings, thus expanding its footprint in advanced biological research and cell and gene therapy.

The deal is expected to close by late 2026 or early 2027, subject to regulatory approvals and Bio-Techne shareholder approval, and will be funded through cash and new debt, with cost synergies of about €140 million targeted by year three after closing.
