Boston Scientific Co (BSX) stock is moving lower today, down about 5.9% from $50.47 to $47.48 over the last eight sessions. The decline is attributed to a recent cybersecurity incident that disrupted the company’s global operations, including order processing and shipping. The attack has raised uncertainty about the speed of recovery and potential shipment delays, causing investors to reassess the stock’s growth prospects.
What Happened
Boston Scientific disclosed a cyberattack that caused global disruptions to its operations on August 26, 2026. The incident halted key functions such as order processing and shipping, and the company has not yet determined the financial impact. The disruption has led to a sharp sell-off, with shares falling to a session low of $46.50 during the day. The stock opened at $46.87 and has traded in a narrow range since, with volume at 15.1 million shares, or 0.7 times the 3-month average. The market appears to be pricing in near-term operational and revenue risks, particularly as the medical device maker is still assessing the full scope of the attack.
What The Data Shows
The stock has been volatile over the past year, trading between $42.20 and $109.50. It currently trades at a price-to-earnings ratio of 18.9, with a revenue growth of 13.5% in the trailing twelve months. Despite a net margin of 17.5%, the recent operational disruption has caused sentiment to deteriorate, with a 7-day average sentiment score of 39 out of 100. Recent insider activity has been positive, with five buys totaling $9.5 million reported in the last 90 days. Notably, two directors, Morano Susan E and Habiger David C, made purchases in early August. Meanwhile, the stock has printed eight fresh 52-week lows on August 28, underscoring the depth of the recent selloff.
What To Watch
Boston Scientific has not yet disclosed the financial impact of the cyberattack, so investors will be watching for further updates. The company’s ability to restore operations and mitigate shipment delays will be key factors in the stock’s near-term performance.
