INTRODUCTION
STERIS plc is a leading provider of infection prevention and other procedural products and services. Our MISSION IS TO HELP OUR CUSTOMERS CREATE A HEALTHIER AND SAFER WORLD by providing innovative healthcare and life science product and service solutions around the globe. We offer our Customers a unique mix of innovative capital equipment products, such as sterilizers and washers, surgical tables, lights and equipment management systems and connectivity solutions such as operating room integration; consumable products including detergents and gastrointestinal endoscopy accessories and other products; services, including equipment installation and maintenance, microbial reduction of medical devices, instrument and scope repair solutions, laboratory services and outsourced instrument reprocessing.
On March 28, 2019, STERIS plc, a public limited company organized under the laws of England and Wales (“STERIS UK”), completed a redomiciliation from the United Kingdom to Ireland (the “Redomiciliation”). The Redomiciliation was achieved through the insertion of a new Irish public limited holding company (“STERIS Ireland”) on top of STERIS UK pursuant to a court-approved scheme of arrangement under English law (the “Scheme”). Following the Scheme effectiveness, STERIS UK was re-registered as a private limited company with the name STERIS Limited, and STERIS Emerald IE Limited, a company established in Ireland and a wholly-owned direct subsidiary of STERIS Ireland, was interposed as the direct parent company of STERIS UK.
STERIS plc's registered office is located in Dublin, Ireland. STERIS plc has approximately 12,000 employees worldwide. Through our field sales and service and a network of dealers and distributors, we serve Customers in more than 100 countries around the world.
We operate and report in four reportable business segments: Healthcare Products, Healthcare Specialty Services, Life Sciences, and Applied Sterilization Technologies. We disclose a measure of segment income that is consistent with the way management operates and views the business. The accounting policies for reportable segments are the same as those for the consolidated Company. In fiscal 2019, we ceased the allocation of certain corporate costs to our segments to align with internal management measures. The prior period operating income measures have been recast for comparability.
The bulk of our revenues are derived from healthcare provider, pharmaceutical and medical device Customers. Much of the growth in these industries is driven by the aging of the population throughout the world, as an increasing number of individuals are entering their prime healthcare consumption years, and are dependent upon advancement in healthcare delivery, acceptance of new technologies, government policies, and general economic conditions. The pharmaceutical industry has been impacted by increased regulatory scrutiny of cleaning and validation processes, mandating that manufacturers improve their processes. Within healthcare, there is concern regarding the level of hospital acquired infections around the world; increased demand for medical procedures, including preventive screenings such as endoscopies and colonoscopies; and a desire by our Customers to operate more efficiently, all of which are driving increased demand for many of our products and services.
