Rhea-AI Filing Summary

Boston Scientific Corporation (BSX) reports a material cybersecurity incident that caused a global disruption of its information technology systems, temporarily affecting manufacturing and the processing and shipment of customer orders. The company has substantially restored its distribution network, resumed sterilization operations, and restarted manufacturing at most facilities worldwide.

Based on current information, Boston Scientific expects the incident to have a material impact on results for the third quarter and full year 2026 and believes it is unlikely to meet its previously issued net sales growth and adjusted EPS guidance for those periods. The company plans to update its 2026 outlook on October 28, 2026, and does not currently expect a material impact on its long-term financial condition.

Positive

  • Company reports substantial restoration of its distribution network, with major centers processing and shipping orders at or above normal levels.
  • Sterilization facilities and most manufacturing sites globally have resumed operations, supporting ongoing recovery of customer order fulfillment.
  • Management states it does not expect the cybersecurity incident to have a material impact on long-term financial condition.

Negative

  • The cybersecurity incident is expected to have a material impact on results of operations for the third quarter and full year 2026.
  • Boston Scientific now believes it is unlikely to meet its previously provided net sales growth and adjusted EPS guidance for Q3 and full year 2026.
  • A network outage from unauthorized activity disrupted manufacturing and order processing/shipping globally, creating backlogs and operational uncertainty.

Filing Explained

As of the filing, Boston Scientific reports no evidence of ongoing unauthorized access, but its investigation and full operational recovery remain incomplete, so the incident’s ultimate operational and financial effects are not yet fully established.

Material Cybersecurity Incidents regulatory
"Item 1.05 Material Cybersecurity Incidents."
adjusted EPS financial
"net sales growth and adjusted EPS guidance ranges for the third quarter"
Adjusted earnings per share (adjusted eps) is a measure of a company's profit per share that has been modified to exclude certain one-time or unusual items, such as costs from restructuring or asset sales. It provides a clearer picture of the company’s core performance by removing events that may distort the usual earnings. Investors use adjusted eps to better understand a company's ongoing profitability and compare it more accurately over time.
forward-looking statements regulatory
"constitute “forward-looking statements” within the meaning of Section 27A"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
Annual Report on Form 10-K regulatory
"refer to Part I, Item 1A. Risk Factors in our most recent Annual Report on Form 10-K"
An annual report on Form 10‑K is a required, comprehensive filing that publicly traded companies give to regulators and investors summarizing their business, results of operations, detailed financial statements reviewed by independent auditors, material risks, legal issues and management’s discussion of performance. Investors use it like a company’s year‑end report card and medical checkup: it reveals how the business made money, where it is vulnerable, and the facts needed to compare value, judge risk and make informed investment decisions.
material impact financial
"determined that the incident is likely to have a material impact on the Company’s results"
Material impact refers to a significant effect that can influence the overall value, decision-making, or outlook of a business or investment. It matters to investors because such an impact can change the expected success or risk level of an investment, similar to how a major change in a recipe can alter the final taste—it's important enough to influence overall judgment or actions.

Item 1.05 Material Cybersecurity Incidents.

As previously disclosed in a Current Report on Form 8-K filed on August 26, 2026 with the Securities and Exchange Commission, on August 25, 2026, Boston Scientific Corporation (the “Company”) identified a cybersecurity incident that affected certain of its information technology systems and resulted in a global disruption to the Company’s operations. Upon detection, the Company activated its incident response protocols, and since then has been working, with the assistance of third-party cybersecurity experts, to investigate, assess and contain the impact of the incident and to restore operations.

The incident involved unauthorized activity on certain of the Company’s systems that resulted in a network outage affecting access to certain operating systems and business applications, which impacted the Company’s ability to manufacture as well as process and ship customer orders. As of the date of this Current Report on Form 8-K, the Company has not identified evidence of ongoing unauthorized access to its systems. The Company’s investigation of the incident remains ongoing.

The Company continues to make progress in restoring many of the affected systems, including substantial restoration of its distribution network, with major distribution centers now processing and shipping customer orders at or above normal operating levels. Additionally, the Company’s sterilization facilities are now operational and manufacturing has resumed across most facilities globally. While the timeline for a full operational recovery is uncertain, the Company continues to work diligently to fully restore all affected systems.

Based on the information currently available as of the date of this Current Report on Form 8-K, the Company has determined that the incident is likely to have a material impact on the Company’s results of operations for the third quarter and full year 2026. As a result, the Company believes that it is unlikely to meet the net sales growth and adjusted EPS guidance ranges for the third quarter and full year 2026 that the Company previously provided on July 29, 2026. The Company anticipates recovering some portion of the impacted revenue as it continues to ramp operations globally, fulfill customer orders and reduce remaining backlogs, however the full impacts are not yet known. The Company intends to provide an update on its operational and financial outlook for the remainder of fiscal year 2026, incorporating the anticipated impact of the incident, during its planned conference call to discuss financial results and business highlights for the third quarter 2026 to be held on Wednesday, October 28, 2026. As of the date of this Current Report on Form 8-K, the Company does not expect the incident will have a material impact on its long-term financial condition.

New risks and uncertainties may arise from time to time and are difficult to predict. All of these factors are difficult or impossible to predict accurately and many of them are beyond our control. For a further list and description of these and other important risks and uncertainties that may affect our future operations, refer to Part I, Item 1A. Risk Factors in our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission, which we may update in Part II, Item 1A.
