The agreement represents Microsize’s second acquisition from Lonza, following the successful 2022 divestment of its Quakertown, Pennsylvania site. In this transaction, Schedio Group – a Swiss-based provider of jet mills, isolators, spray dryers, and engineering services – is investing alongside Microsize to strengthen and localize its operational base in Europe, advancing a shared vision to lead the next generation of integrated particle engineering solutions.

With more than 30 years of experience, Mic Mac has served the pharmaceutical industry with proven GMP-compliant jet milling and micronization capabilities for both clinical and commercial supply. The site will bring solid European infrastructure, a highly skilled workforce, and a strong regulatory track record to Microsize’s growing platform.

“The acquisition agreement represents a critical step in building Microsize into a global leader in particle engineering,” said TJ Higley, CEO of Microsize. “Mic Mac complements our U.S. operations perfectly, technically, operationally, and culturally. It gives our customers seamless access to high-quality services on both sides of the Atlantic, and expands our ability to support them from early development through commercial scale.”

Jan Vertommen, Vice President, Commercial Development, Lonza Advanced Synthesis, added: “Following Microsize’s acquisition of the Quakertown site in 2022, the acquisition of the Monteggio site will enable Microsize to provide customers specialized micronization services in both the US and Europe. In view of the prior engagements between the companies involved in the transaction we anticipate a smooth transition for the Mic Mac customers.”

Microsize and Schedio will jointly invest in Mic Mac to further enhance its capabilities and accelerate modernization. The partnership aims to establish an integrated European-American network for advanced particle engineering, combining Microsize’s CDMO expertise with Schedio’s process equipment and containment technologies.

“Mic Mac is an excellent fit with our belief in the ‘Power of Together,’” said Mattia Wiedemeier, CCO of Schedio Group. “Together with Microsize, we will deliver not just capacity, but innovation and agility to customers who rely on us for safety, quality, and speed. This agreement to acquire Mic Mac supports our mission to lead the next generation of integrated particle engineering solutions.”

Derek Hennecke, Chairman of Microsize, added: “With Mic Mac, Microsize will become the most focused global platform for particle size control, spanning two continents and decades of operational excellence. This is a deliberate strategy to build scale and specialization in a market that rewards technical depth, customer trust, and execution.”

The transaction is expected to close during the first quarter of 2026 subject to customary closing conditions.
