Boston Scientific
Boston Scientific's revenue rose 19.9% to $20.1 billion in fiscal 2025. Its operating margin was 18.0%, up from 15.5% a year earlier. Free cash flow was $3.7 billion, up 38.3%. The diluted share count rose 0.6%.
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.
What Boston Scientific does
Boston Scientific develops, makes and sells medical devices used in less-invasive procedures, which are alternatives to surgery. Its products help doctors diagnose and treat heart, lung, digestive, cancer, nerve and urinary conditions. Customers are mainly hospitals and the physicians who use its devices. The company has been in the business for more than 45 years and sells around the world.
It reports two segments, MedSurg and Cardiovascular. In late 2025 it combined its Cardiology and Peripheral Interventions businesses into a single Cardiovascular business, which did not change the two reported segments. MedSurg includes Endoscopy, whose devices diagnose and treat digestive and bile duct conditions and support weight loss in patients with obesity. The company earns revenue by selling these devices.
Boston Scientific says it competes with other medical device makers that move fast on technology and offer lower-cost products. It has bought many companies in recent years to expand its businesses, and it says it plans to keep investing in new products and in markets outside the United States.
Its biggest risks, as it describes them
- Intense competition and fast technology change, including lower-cost rival products.
- Declines in market size, average selling prices or procedure volumes.
- Failing to integrate acquired companies or to pick successful acquisitions.
- Needing to develop new products, which takes heavy research and clinical testing.
- Supply chain or factory disruptions, and shortages of materials, components or sterilization services.

Revenue and margins
Net income and earnings per share
From fiscal 2016 to 2025, earnings per share grew 25.6% a year and net income 26.6% a year, as new shares raised the share count by 9% and diluted each share's earnings.

Valuation
Two ways to value Boston Scientific 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 Boston Scientific'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 Boston Scientific's fiscal 2025 free cash flow of $3.7B, net cash of −$9.2B at December 31, 2025 and 1,494 million diluted shares, from its filings. The scenarios are fitted to Boston Scientific: the base scenario's growth in years 1 to 5 is its revenue growth over the last 3 years, 16.5% 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 Boston Scientific's earnings per share of $2.47 (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: 28×, the middle of Boston Scientific's own P/E today, its peers' median and its sector's median (the Health Care median) 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.
