PE-backed Mirion acquires Capintec

Mirion Technologies, which is backed by Charterhouse, has acquired Capintec Inc, a provider of calibration and measurement technologies for nuclear medicine applications. No financial terms were disclosed.


On July 9, 2019, Mirion Technologies (“Mirion”) acquired Capintec, Inc. (“Capintec”), a leading supplier of calibration and measurement technologies for nuclear medicine applications. The acquisition of Capintec is consistent with Mirion’s inorganic strategic expansion plan, which is focused on enhancing Mirion’s portfolio of industry leading technology offerings across a range of core and adjacent end markets.

To fund its expansion plan, Mirion closed a $34 million add-on to its term loan B on July 8, 2019 with Morgan Stanley Senior Funding, Inc. serving as lead arranger. The add-on financing was well received by lenders as it priced at the tight end of initial price talk and was oversubscribed. Consistent with management’s strategic roadmap, Mirion has engaged financial advisors to assist in evaluating a range of strategic options for the company.

Backed by Charterhouse Capital Partners, Mirion is a leading provider of detection, measurement, analysis and monitoring solutions to the nuclear, defense, medical and research end markets. Since being acquired by Charterhouse in 2015, Mirion has been an active acquiror beginning with its transformational acquisition of Canberra in 2016, followed by multiple smaller “bolt-on” deals. Together, these acquisitions have materially enhanced Mirion’s global reach with a broad portfolio of product offerings. Mirion has facilities in Europe, Asia, and North America and is headquartered in San Ramon, California. For additional information, please visit:
