Casella Holdings Limited – an instrumental (i)deal

05 October 2022

Our M&A team has successfully advised on the corporate carve out and sale of Casella Holdings Limited (Casella), a subsidiary of IDEAL Industries, Inc (IDEAL) to TSI Instruments Limited (TSI).

The client

Established in 1799 and based in Bedford, UK, with a presence in the US, China, and India, Casella is a global leader in the occupational hygiene and environmental monitoring market. It manufactures a range of test, measurement, and monitoring instrumentation, including real-time dust monitors, personal sampling pumps, sound level meters, vibration monitors, and outdoor boundary monitoring systems.

The sale represents a strategic divestiture of a non-core asset by IDEAL, a global manufacturer of professional electrician products, high power density connectors, and superior charging systems, to TSI, a subsidiary of Minnesota-based TSI Incorporated, an industry leader in the design and production of precision instruments.

RSM’s solution

Our M&A team advised the IDEAL Board on the transaction, using our deep sector knowledge to package the opportunity and identify suitable purchasers, managing a discreet process and negotiating all aspects of the deal. The sale of Casella adds to a growing number of corporate carve-outs we have advised on while building our credentials in regulatory-driven markets across health and safety. 

Transaction team: Helen Brocklebank, Oliver Currie, Mikey Goodwin, and Louise Berrie


‘I am delighted that RSM has secured a new home for Casella. This was a technically challenging disposal and finding the correct M&A team with the experience and understanding of complex corporate carve-outs was essential. As our people are at the heart of our business, our goal was also to find a buyer who shared our values and would ensure the continued success of Casella. The RSM team were committed to delivering our objectives. They were detailed, thorough, and dedicated and this ultimately led to a great outcome for IDEAL and the Casella team. Thank you to RSM for helping us to achieve a great result.’
