Description of the Company	Description of the Company Masimo Corporation (the Company) is a global medical technology company that develops, manufactures and markets a variety of noninvasive patient monitoring technologies. The Company’s mission is to improve patient outcomes and reduce the cost of care. The Company’s patient monitoring solutions generally incorporate a monitor or circuit board, proprietary single-patient use or reusable sensors, software and/or cables. The Company primarily sells its products to hospitals, emergency medical service providers, home care providers, physician offices, veterinarians, long term care facilities and consumers through its direct sales force, distributors and original equipment manufacturer (OEM) partners. The Company invented Masimo Signal Extraction Technology^®(SET^®), which provides the capabilities of Measure-through Motion and Low Perfusion^™ pulse oximetry to address the primary limitations of conventional pulse oximetry. Over the years, the Company’s product offerings have expanded significantly to also include rainbow^® Pulse CO-Oximetry, with its ability to measure and monitor carboxyhemoglobin (SpCO^®), methemoglobin (SpMet^®), total hemoglobin concentration (SpHb^®), fractional arterial oxygen saturation (SpfO₂^™), Oxygen Content (SpOC^™), Pleth Variability Index (PVi^®), rainbow^® Pleth Variability Index (RPVi^™), respiration rate from the pleth (RRp^®) and Oxygen Reserve Index (ORi^™); acoustic respiration monitoring (RRa^®), electrical brain function monitoring (SedLine^®), and optical gas monitoring. The Company also developed the Root^™ patient monitoring and connectivity platform, the Radical-7^®and Rad-97^™ bedside and portable patient monitors, the Radius-7^® wearable wireless patient monitor and the Masimo Patient SafetyNet¹ remote patient surveillance monitoring system. These solutions and related products are based upon Masimo SET^®, rainbow^® and other proprietary algorithms. These software-based technologies are incorporated into a variety of product platforms depending on customers’ specifications. This technology is supported by a substantial intellectual property portfolio that the Company has built through internal development and, to a lesser extent, acquisitions and license agreements.
