Dexcom
Dexcom's revenue rose 15.6% to $4.7 billion in fiscal 2025. Its operating margin was 19.6%, up from 14.9% a year earlier. Free cash flow was $1.1 billion, up 70.8%. It paid out $500 million in dividends and buybacks, 46% of free cash flow. The diluted share count fell 1.7%.
Operating margin is operating income as a share of revenue. Free cash flow is cash from operations minus capital spending. Return on capital is after-tax operating income as a share of the money invested in the business: debt plus equity, minus cash. Market cap is the last closing share price times the latest diluted share count, so it is approximate. P/E is the last close divided by diluted earnings per share over the last four quarters, or the latest fiscal year where the quarters aren't available; there is none when the company made a loss.
Charts show fiscal years, from the 10-K filings.
Revenue and margins
Net income and earnings per share
From fiscal 2019 to 2025, earnings per share grew 11.3% a year and net income 42.2% a year, as new shares raised the share count by 339% and diluted each share's earnings.

Valuation
Two ways to value Dexcom yourself, both starting from its filings: a discounted cash flow model and the price-to-earnings method.
Discounted cash flow (DCF)
A discounted cash flow (DCF) model values a business as the cash it may generate in future, discounted back to today. The starting figures come from Dexcom's 10-K (or, for net cash and shares, its latest 10-Q) and the assumptions are yours: start from one of three example scenarios, then change any figure to see what it implies for a share, and how that compares with the last share price.
Value per share on three example scenarios, from Dexcom's fiscal 2025 free cash flow of $1.1B, net cash of $696M at December 31, 2025 and 406 million diluted shares, from its filings. The scenarios are fitted to Dexcom: the base scenario's growth in years 1 to 5 is its revenue growth over the last 3 years, 17.0% a year; the cautious and optimistic ones are lower and higher, and growth in years 6 to 10 is halfway to the long-run rate. The base scenario's discount rate is 9% for a business of moderate risk (Health Care Equipment); the cautious and optimistic ones use a point more and a point less. Select one to load it into the calculator. These are the model's arithmetic on those assumptions, not a forecast or a price target.

How the value changes with two assumptions
Price-to-earnings (P/E) method
Another common way to value a company is to multiply its earnings per share by a price-to-earnings (P/E) multiple: the number of years of today's earnings an investor pays for a share. A higher multiple usually means investors expect earnings to grow. Choose a multiple, for example from similar companies, to see the value it gives.
Value per share on three example scenarios, from Dexcom's earnings per share of $2.52 (over the last four quarters). Each grows earnings for a year at the cash flow scenarios' rates and applies a multiple to next year's earnings: 31.2×, the middle of Dexcom's own P/E today, its peers' median and its sector's median (Dexcom's own P/E today) for the base scenario, 20% less and more for the cautious and optimistic ones. The price is brought back a year at 10%, 9% and 8%. Select one to load it into the calculator. These are the model's arithmetic on those assumptions, not a forecast or a price target.
