About

Dexcom, Inc. is a San Diego, California-based diabetes management technology company — publicly traded on NASDAQ (NASDAQ: DXCM) as an S&P 500 Health Care component — developing and commercializing continuous glucose monitoring (CGM) systems for people with Type 1 diabetes, Type 2 diabetes, and pre-diabetes through approximately 9,000 employees worldwide. Dexcom's G7 CGM system (a small wearable sensor and transmitter worn on the body that measures glucose continuously every 5 minutes without fingerstick calibration) is the market-leading prescription CGM for insulin-using patients — enabling tight glucose management that prevents hypoglycemic episodes, reduces A1c levels, and improves outcomes for the 8+ million US patients using insulin. In 2024, Dexcom launched Stelo — the first FDA-cleared over-the-counter CGM in the United States, requiring no prescription and targeting the approximately 25 million US adults with Type 2 diabetes who do not use insulin, pre-diabetes patients, and health-conscious consumers seeking metabolic insights. The Stelo OTC CGM integrates with the Oura Ring (wearable health tracking) through a strategic partnership announced in November 2024, with Dexcom investing $75 million in ŌURA and the companies launching Stelo integration in the Oura app — giving users 24/7 glucose insights alongside sleep, heart rate, and activity data from the Oura Ring. Dexcom reported full year 2024 revenue of approximately $3.9 billion, with continued CGM market penetration driving growth.
