Boston Scientific stock (ISIN US10117L1017) closed at USD 43.87 on September 15, 2026, down 2.62 percent from the prior close, while the market value stood at USD 63.578 billion. Yahoo Finance also shows a 52-week range of USD 42.20 to USD 105.65 and YTD performance of minus 53.99 percent.

Cyberattack cuts into guidance

Boston Scientific said its manufacturing, order fulfillment and shipping operations were restored after a cybersecurity incident that disrupted global operations on August 25, 2026, according to Digital Health News on September 16, 2026. The same report said the company expected to miss third-quarter and full-year sales and earnings guidance because of the disruption.

The report also said Boston Scientific's distribution network was back at or above normal levels as it worked through backlogs, and that some customers could still face temporary delays. The incident matters because the market is now weighing recovery speed against the guidance hit.

Q2 numbers set the bar

On Yahoo Finance, Boston Scientific's Q2 FY26 revenue is shown at USD 5.44 billion and earnings at USD 907 million, with normalized EPS of USD 0.86 versus an estimate of USD 0.83. The same snapshot lists a profit margin of 16.67 percent, which gives investors a concrete base line before the guidance reset.

The stock also carries a 1-year target estimate of USD 62.00 on Yahoo Finance, and BTIG kept a Buy rating while cutting its price target from USD 60 to USD 56 on September 9, 2026, according to the same page. That leaves the shares well below the target range even after a still-large gap to the 52-week high.

Price below its range

Boston Scientific stock traded at USD 43.87 at the September 15 close on the NYSE, with volume of 15,990,757 shares and a day range of USD 43.68 to USD 44.99. The stock sat 58.48 percent below its 52-week high of USD 105.65, a distance that underlines how much of the recent story is already in the price.
