Overview
Cantel Medical Corporation was an American medical-equipment company headquartered in Little Falls, New Jersey. Founded in 1963 by Charles M. Diker, the company developed and sold products and services intended to support infection prevention and the safe operation of healthcare facilities. Its activities covered several adjacent areas of medical technology, including automated endoscope reprocessing, medical water purification, dialysis concentrates, and dental-instrument processing. The company’s business model combined internally developed products with growth through acquisitions. Its portfolio included the MEDIVATORS business, associated with endoscope reprocessing and related infection-control equipment, and Mar Cor Purification, which supplied water-treatment technologies for healthcare applications. These offerings addressed hospitals, outpatient and specialist clinics, dialysis providers, dental practices, and other institutional healthcare customers. The common theme across the portfolio was the reduction of contamination risk and the provision of controlled processing or purified water in clinical environments. Cantel expanded through a series of acquisitions. In 2001 it purchased Minntech Corporation for a reported $70 million, broadening its medical-technology activities. In March 2018 it acquired Belgium-based Aexis Medical for $24.8 million. In January 2019 it bought Vista Research Group, an Ohio-based company, for $10.5 million. Later that year, in October 2019, it acquired Hu-Friedy, a Chicago-based manufacturer of dental instruments, for $719.4 million. The Hu-Friedy transaction extended Cantel’s infection-prevention proposition into dental instrumentation and related processing workflows. Cantel operated as a publicly traded company under the ticker CMD. Its business was international in reach, although its corporate base remained in the United States. The company ceased to exist as an independent public company after STERIS acquired it in June 2021. Following the transaction, Cantel’s product lines and businesses became part of STERIS’s broader healthcare and infection-prevention portfolio. Cantel is therefore best understood today as a former standalone medical-technology company and as a group of businesses and brands integrated into STERIS rather than as an independent operating corporation.
History
Cantel Medical Corporation was established in 1963 by Charles M. Diker in Little Falls, New Jersey. It grew as a medical-equipment company serving healthcare institutions with technologies connected to infection prevention and clinical equipment processing. Rather than concentrating on a single device category, Cantel assembled a portfolio spanning endoscope reprocessing, medical water purification, dialysis concentrates, and dental instrumentation. A significant stage in the company’s development came in 2001, when Cantel purchased Minntech Corporation for a reported $70 million. The acquisition strengthened Cantel’s position in medical technology and contributed to the company’s expansion beyond its original operating base. Over time, Cantel’s portfolio came to include MEDIVATORS, a business associated with endoscope reprocessing and infection-control equipment, and Mar Cor Purification, which focused on water-treatment systems for healthcare environments. Cantel continued its acquisition-led expansion in the late 2010s. In March 2018, it acquired Aexis Medical of Belgium for a reported $24.8 million. The transaction added an international business to Cantel’s platform. In January 2019, Cantel bought Vista Research Group, based in Ashland, Ohio, for a reported $10.5 million. Later in 2019, the company completed the much larger acquisition of Hu-Friedy, a Chicago-based dental-instrument manufacturer, for a reported $719.4 million. Hu-Friedy broadened Cantel’s reach into dentistry and connected dental instruments with the company’s existing emphasis on cleaning, disinfection, sterilization, and infection prevention. The resulting company served a range of healthcare customers, including hospitals, clinics, dialysis centers, and dental practices. Its products supported workflows in which equipment, instruments, and water quality had to be controlled to meet clinical and operational requirements. Cantel’s international activities and acquisition portfolio made it a broader healthcare-infrastructure supplier rather than a narrowly focused equipment manufacturer. Cantel remained publicly traded under the ticker CMD until its acquisition by STERIS in June 2021. The transaction ended Cantel’s status as an independent public company. Its businesses and product lines were incorporated into STERIS, a larger medical-equipment and infection-prevention company. Consequently, Cantel Medical Corporation is now a historical corporate entity and a former public company; some of its brands and operations continue within the STERIS organization.
