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.
Marlborough MA cardiac devices leader (NYSE: BSX) $16.7B FY2024 revenue (+18%); Farapulse PFA ablation fastest-growing EP device, WATCHMAN FLX 70%+ LAAC share, competing with Abbott and Medtronic.
About
Boston Scientific Corporation is a Marlborough, Massachusetts-based global medical device company — publicly traded on the New York Stock Exchange (NYSE: BSX) as an S&P 500 Health Care component — developing and commercializing medical devices for minimally invasive diagnosis and treatment of cardiovascular disease, cardiac rhythm management, electrophysiology, urology, endoscopy, and neuromodulation through approximately 48,000 employees in 130 countries. In fiscal year 2024, Boston Scientific reported revenues of $16.7 billion (+18% year-over-year) — driven by the Farapulse pulsed field ablation (PFA) system for atrial fibrillation treatment, WATCHMAN FLX left atrial appendage closure (LAAC) device, and Rhythmia Ultra high-density cardiac mapping — making Boston Scientific the fastest-growing large-cap medical device company and one of the strongest organic growth stories in healthcare. CEO Mike Mahoney has executed acquisitions and organic R&D investment to build a diverse cardiovascular and electrophysiology portfolio: the 2023 acquisition of Apollo Endosurgery ($615 million, flexible endoscopic stapling for minimally invasive procedures) and the 2022 acquisition of Lumenis (surgical laser systems) expanded Boston Scientific beyond the cardiac core. Boston Scientific's strongest 2024 growth driver — Farapulse (pulsed field ablation) — achieved rapid adoption as a new standard-of-care in atrial fibrillation ablation by delivering shorter procedure times (2-hour PFA versus 4-hour radiofrequency ablation) and improved safety profile compared to traditional thermal ablation methods.
