On February 23, 2016, Spectris Group Holdings Ltd announced that it has completed the acquisition of the privately-owned business, CAS Clean-Air-Service AG (CAS).

Established in 1989 in Wattwil, Switzerland, CAS has become a leading cleanroom-service company, providing measurement services, process qualification, calibration services and product sales, primarily to the pharmaceutical manufacturing market. CAS generates annual revenue of around CHF 10 million, of which services represent approximately 85%. CAS will be integrated into Particle Measuring Systems (PMS) within Spectris' Materials Analysis segment and the CAS name will remain a distinct service brand within PMS.

Spectris was advised by Homburger in this transaction. The Homburger team was led by partner Dieter Gericke (Corporate | M&A) and included Nathalie Högger (lead associate, Corporate | M&A) and Kerstin Schiwow-Amrhein (associate, Competition | Regulatory) as well as junior associates Nicolas Jauslin (Corporate | M&A) and Julia Käser (Competition | Regulatory).
