Masimo Corporation (MASI) Stock Analysis & Winston Score

Masimo Corporation makes medical monitoring devices used in hospitals and clinics around the world. Its most well-known product is a pulse oximeter — a sensor that measures oxygen levels in a patient's blood without breaking the skin. Masimo's technology is used by nurses and doctors to track patients in intensive care units, operating rooms, and emergency departments. Masimo earns money by selling its monitoring hardware and then charging hospitals ongoing fees for the disposable sensors and software that go with it — a model that creates recurring revenue. The company operates globally, with a large share of sales in the United States, and its patented Signal Extraction Technology gives it a strong edge over cheaper competitors by working accurately even when patients move or have poor circulation. A key risk is Masimo's ongoing effort to expand into consumer health wearables, which puts it in direct competition with much larger companies like Apple and has drawn significant investor scrutiny in recent years.
