DexCom makes continuous glucose monitors (CGMs) that let diabetics track blood sugar in real time without finger-prick tests—think a wearable sensor that beams data to a phone.
Money comes from selling CGM systems and sensors, with gross margins around 62% and net margins near 20%—recurring revenue from disposable sensors drives the model.
DexCom's integrated hardware, software, and clinical data create switching costs for patients and doctors, but Abbott's FreeStyle Libre is aggressively undercutting on price and expanding access, eroding DexCom's lead.
