Part 1 · What the company is worth

Overview

DexCom makes continuous glucose monitors — small wearable sensors that track blood sugar every few minutes and send readings to a phone or an insulin pump, replacing the finger-prick test that diabetics used for decades. Its main product line is the G7 sensor and its Stelo variant for people not on insulin. It sells almost entirely one category of medical device, in two markets — the United States and abroad — rather than a diversified portfolio.

How it makes money

DexCom earns revenue mainly by selling a recurring supply: sensors that must be replaced every 10-15 days and transmitters replaced less often, so once a patient starts, the ongoing sensor purchases resemble a subscription even though they are billed per shipment. Sales flow largely through distributors and pharmacies who bill insurers or government payers on the patient's behalf, and reimbursement approval from insurance or Medicare, not the patient's own spending, determines whether a sale happens at all.

Revenue by segment

United States71.5%

Sales to US patients, mostly billed through insurance or Medicare via distributors and pharmacies — where DexCom has been established longest.

International28.5%

Sales outside the US, growing faster than the domestic market as DexCom expands reimbursement coverage abroad.

Competitive moat

Switching costs · Narrow

Patients build months or years of glucose history and habits around one sensor and app, and DexCom's sensors are integrated with several insulin pump makers' systems, so switching means a new prescription, a new pump pairing and relearning the device. That keeps most patients in place once started, but Abbott's FreeStyle Libre competes closely on price and features, so the advantage is not decisive.

What drives demand

Defensive

Demand is driven by the number of people with diabetes who are prescribed a continuous monitor, a population that grows steadily regardless of the economic cycle, plus the pace at which insurers extend reimbursement to more patient groups. Growth can still slow when a competitor cuts price or when a payer tightens coverage rules, but the underlying need for glucose monitoring does not disappear in a downturn.

Key risks

  • Reliance on a small number of distributors — Most sales are routed through a handful of pharmacy and medical-supply distributors rather than direct to patients; losing one or a change in its terms would disrupt a large share of shipments.
  • Single-source manufacturing and FDA oversight — Some components come from single-source suppliers, and DexCom's factories and any product change remain subject to FDA inspection and approval; a failed inspection or an unauthorized change can halt shipments.
  • Reimbursement decisions by insurers and Medicare — A sale generally only happens if an insurer or government payer agrees to reimburse the device; a coverage cut or a slower approval process for new patient groups directly reduces revenue.
  • Competition from Abbott and other monitor makers — Abbott's FreeStyle Libre and other continuous glucose monitors compete directly on price, accuracy and insurer coverage, and a lost contract with a major payer can shift patients to a rival overnight.

Customer concentration

DexCom sells through a small number of large distributors and pharmacy partners rather than directly to most patients; the company has not disclosed a current percentage for its largest partners, but historically a handful of them each represented a meaningful share of revenue.

The case for

Buyers argue that the diabetic population needing continuous monitoring keeps growing, that recurring sensor purchases behave like a subscription once a patient is on the device, and that expanding international reimbursement gives DexCom years of runway outside its largest market.

The case against

Sellers fear that Abbott's Libre competes aggressively on price, that reimbursement decisions outside the company's control can cut off whole patient groups, and that dependence on a handful of distributors and single-source suppliers leaves little room for a manufacturing or regulatory setback.
