US investment company Carlyle buys Czech microscope manufacturer

Carlyle's acquisition of Tescan Orsay Holding in the Czech Republic was one of the largest M&A transactions of 2022 and should ensure long-term growth for the Czech leading developer and supplier of high-end analytical instruments. The Deloitte Debt & Capital Advisory team worked with leading global investor The Carlyle Group to secure financing for the acquisition.


Tescan was founded in 1991 and is based in Brno. It is a leading global developer and supplier of scanning electron microscopes, focused ion beam scanning electron microscopes, micro-CT scanners and 4D scanning transmission electron microscopes. Tescan Orsay Holding was formed in 2013 through the merger of Tescan with Orsay Physics, which pioneered the development of focused ion beam scanning electron microscopes.

The company currently has over 750 employees in 14 plants located around the world, including two in Brno. In 2021, it achieved sales of CZK 2.5 billion and supplies its products to semiconductor manufacturers, research laboratories, prestigious universities and innovative industrial and manufacturing companies.

Investment firm Carlyle has a long history of investing in this sector and therefore has extensive experience in partnering with and scaling similar technology businesses. It plans to support Tescan Orsay Holding's future growth by investing in new innovative products and entering other markets.

"This project underlines Deloitte's expertise in debt and equity advisory and its ability to add value beyond leading financial sponsors in complex cross-border transactions."
