Patterson Dental Supply, Inc.
Patterson Veterinary Supply, Inc.
Patterson Medical Supply, Inc.
Patterson Companies Inc is a medical supplies conglomerate primarily in the business of veterinary and dental products (ranging from xray equipment to consumable products, dental consumables make up the biggest part of the dental industry). Since 2003 it also distributes general medical rehabilitative devices like braces and wheel chairs. Traditionally a dental company it diversified its business at the turn of the millennium when it acquired 55-year-old company JA Webster Inc, a distributor of veterinary products. That business segment (now known as Patterson Veterinary) currently distributes equipment (diagnostic and surgical) and medicine (anaesthetics, vaccines). The company operates directly in only the US and Canada (in Canada through subsidiaries Sammons Preston Canada and Patterson Dental Canada).
In 2008 it was noted as having one of the lowest debt ratios among companies in the health care sector. Patterson was also a member of the Nasdaq-100 until December 10, 2010 when it and six other companies were replaced. The Nasdaq-100 is composed of the 100 largest non financial stocks traded on the Nasdaq.
Patterson is the distribution company for Sirona Dental Systems, one of the world's biggest dental equipment manufacturers. More recently the company has been active in making acquisitions abroad; On June 17, 2010 Patterson Medical purchased the rehabilitation part of Ireland-based DCC Healthcare (Days Healthcare, Physiomed and Ausmedic) in a move that increased Patterson Medical's revenue by 16.43% (US$70 million, fiscal year ended April 24, 2010). The new companies were added to its Homecraft Rolyan unit in the UK.
The company traces its roots through division Patterson Dental Supply back to one established in 1878 named Patterson Dental Company. It remained focused solely on the dental products market until the 21st century when it branched out into the veterinary supplies market through 2 large acquisitions, JA Webster in 2001 (92.5 million dollars) and ProVet in 2004. For about 130 years it dealt only in dental supplies. It began selling rehabilitation supplies in 2004 after acquiring Ability One Products Corporation followed by Medco the same year.
It went public on the Nasdaq in 1992 with an IPO of around 480 million dollars.
