Lonza to acquire Merck KGaA’s U.S. CDMO network

Lonza signed a definitive agreement to buy five U.S. contract development and manufacturing sites from Merck KGaA. The transaction is valued in the low‑ to mid‑triple‑digit million range in Swiss francs and will add about 1,100 employees to Lonza’s workforce. Lonza expects the acquired sites to generate roughly CHF 250 million in sales by 2028, and the deal is slated to close in mid‑2027, funded with cash and existing credit facilities. Merck will use the proceeds to sharpen its focus on innovation‑driven life‑science businesses.

Merck’s divestiture sharpens its portfolio and frees resources for core innovation, as the company says. Lonza’s expanded U.S. footprint increases its manufacturing capacity for high‑growth modalities, which could boost its revenue stream, according to the company’s guidance.
