Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q (this Quarterly Report) contains statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements may be identified by words like “anticipate,” “expect,” “project,” “believe,” “plan,” “estimate,” “intend,” “aim,” "goal," "target," "continue," "hope," "may" and similar words. These forward-looking statements include, among other things, statements regarding our financial and operating performance; acquisitions; clinical trials; business plans and product performance; new and anticipated product approvals and launches; intellectual property; regulations and accounting pronouncements; legal proceedings; tax matters and regulations; and macroeconomic and geopolitical conditions. These forward-looking statements are based on our beliefs, assumptions and estimates using information available to us at the time and are not intended to be guarantees of future events or performance. If our underlying assumptions turn out to be incorrect, or if certain risks or uncertainties materialize, actual results could vary materially from the expectations and projections expressed or implied by our forward-looking statements.

The forward-looking statements in this Quarterly Report are based on certain risks and uncertainties, including the risk factors described in Item 1A under the heading Risk Factors in our most recent Annual Report on Form 10-K and the specific risk factors discussed herein and in connection with forward-looking statements made throughout this Quarterly Report, which could cause actual results to vary materially from the expectations and projections expressed or implied by our forward-looking statements. These risks and uncertainties, in some cases, have affected and in the future could affect our ability to implement our business strategy and may cause actual results to differ materially from those contemplated by the statements expressed in this Quarterly Report. As a result, readers are cautioned not to place undue reliance on any of our forward-looking statements. Risks and uncertainties that may cause such differences include, among other things: economic conditions, including the impact of foreign currency fluctuations; future U.S. and global political, competitive, reimbursement and regulatory conditions, including changing trade and tariff policies; geopolitical events, conflicts and tensions; manufacturing, distribution and supply chain disruptions and cost increases; disruptions caused by cybersecurity events; disruptions caused by public health emergencies or extreme weather or other climate change-related events; labor shortages and increases in labor costs; variations in outcomes of ongoing and future clinical trials and market studies; new product introductions and the market acceptance of those products; market competition for our products; expected pricing environment; expected procedural volumes; the closing and integration of acquisitions; demographic trends; intellectual property rights; litigation; financial market conditions; the execution and effect of our restructuring program; the execution and effect of our business strategy, including our cost-savings and growth initiatives; our ability to achieve sustainability goals; and future business decisions made by us and our competitors. 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, see Item 1A. Risk Factors in our most recent Annual Report on Form 10-K, which we may update in Part II, Item 1A. Risk Factors in Quarterly Reports on Form 10-Q that we have filed or will file hereafter. We disclaim any intention or obligation to publicly update or revise any forward-looking statement to reflect any change in our expectations or in events, conditions, or circumstances on which those expectations may be based, or that may affect the likelihood that actual results will differ from those contained in the forward-looking statements, except as required by law. This cautionary statement is applicable to all forward-looking statements contained in this Quarterly Report.
