Explanatory Note

This Amendment No.1 (the "Amendment") amends the Current Report on Form filed by Stryker Corporation (the "Company") with the Securities and Exchange Commission (the "SEC") on March 11, 2026 (the March 11, 2026, referred hereinto as the "Original Report").

As previously disclosed in the Original Report and as further reported on two Item 7.01 Current Reports on Form furnished to the SEC on March 12, 2026, and March 23, 2026 respectively, on March 11, 2026, the Company identified a cybersecurity incident, which when it occurred, caused disruptions to the Company's business operations. Since then, the Company has worked diligently, together with third-party experts and law enforcement, to contain and neutralize the impact of the incident and restore operations. The Company's investigation of the incident remains ongoing.

Based on the information currently available to the Company, and assessment of both quantitative and qualitative factors that emerged in the weeks following the incident, the Company has determined that the incident had a material impact on its operations, with resulting impact to the Company's financial results for the first quarter of 2026. In reaching this determination, the Company considered factors including the scope and duration of the operational disruption, the systems affected and the potential for customer, regulatory and other impacts.

The Company believes that the incident has not had, and is not reasonably likely to have, a material impact on the Company's 2026 full-year guidance.

As of the date of this Amendment, the Company is fully operational across its global manufacturing network and commercial, ordering and distribution systems have been restored.

The Company is scheduled to report earnings for its first quarter of fiscal year 2026 on April 30, 2026, where it will discuss its financial results and components of its full-year guidance in further detail.

The information furnished under Item 7.01 of this Amendment, shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
