Company Overview
About Dexcom
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.
Business Model & Competitive Advantage
Dexcom's CGM platform model creates competitive advantage through clinical accuracy, ecosystem integration, and insurance reimbursement coverage: the Dexcom G7's FDA-cleared MARD (mean absolute relative difference) accuracy of 8.2% sets the clinical standard that competing CGM systems must meet to gain formulary placement on insurance plans that cover CGM for insulin-using diabetics — and Dexcom's clinical data package (from 10+ years of G4/G5/G6/G7 real-world use) provides the payer evidence that newly entered competitors (from consumer health companies) cannot immediately replicate. The integration of Dexcom CGM data with insulin pumps (closed-loop artificial pancreas systems from Tandem Diabetes Care and Insulet OmniPod), insulin pen systems, and electronic health records creates a data-connected care ecosystem where Dexcom sits at the center of diabetes management workflow — generating value for patients, clinicians, and payers that individual CGM sensor sales alone do not capture.
Competitive Landscape 2025–2026
In 2025, Dexcom competes in continuous glucose monitoring and diabetes management technology against Abbott Laboratories (NYSE: ABT, FreeStyle Libre CGM — the global market share leader by installed user base in Type 2 diabetes), Medtronic (NYSE: MDT, Guardian 4 CGM and MiniMed insulin pump integration), and emerging consumer health CGMs from Levels, Supersapiens, and NutriSense for the prescription diabetes management market and the emerging OTC metabolic monitoring market. Stelo's OTC positioning opens the massive non-insulin Type 2 diabetes market (25M US patients) and the "metabolic wellness" consumer market — where health-conscious non-diabetics seek continuous glucose data to optimize diet, exercise, and sleep — a market where Apple Watch (NYSE: AAPL), Samsung Galaxy Watch, and Google (NASDAQ: GOOGL) have announced CGM feature development ambitions. The $75M Oura investment and Stelo-Oura integration represents Dexcom's strategy to embed CGM in the consumer wellness wearable ecosystem before big tech platforms commoditize glucose sensing. The 2025 strategy focuses on Stelo consumer market growth, G7 prescription market share maintenance, and CGM integration with GLP-1 medication management (Ozempic, Wegovy patients who benefit from CGM monitoring).
