Forward-Looking Statements

This Annual Report on Form 10-K and our other publicly available documents include 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 (Exchange Act), and are subject to the safe harbor created thereby under the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts, and generally can be identified by the use of words such as "may," "could," "aim," "seek," "believe," "will," "expect," "project," "estimate," "intend," "target," "anticipate," "plan," "continue," or similar expressions or future or conditional verbs.

Forward-looking statements inherently involve many risks and uncertainties that could cause actual results to differ from those expressed in forward-looking statements. Forward-looking statements are based on management's current plans and expectations, expressed in good faith and believed to have a reasonable basis. However, we can give no assurance that any expectation or belief will result or will be achieved or accomplished. Investors therefore should not place undue reliance on forward-looking statements. The following include some but not all of the factors that could cause actual results or events to differ from those anticipated:

• the significant costs and uncertainties in the pharmaceutical research and development process, including with respect to the timing and process of obtaining regulatory approvals;

• the impact and uncertain outcome of acquisitions and business development transactions and related costs;

• intense competition affecting our products, pipeline or industry;

• market uptake of launched products and indications;

• continued pricing pressures and the impact of actions of governmental and private payers affecting pricing of, reimbursement for, and patient access to pharmaceuticals, or reporting obligations related thereto;

• safety or efficacy concerns associated with our products;

• dependence on relatively few products or product classes for a significant percentage of our total revenue and an increasingly consolidated supply chain;

• the expiration of intellectual property protection for certain of our products and competition from generic and biosimilar products, and risks from the proliferation of counterfeit or illegally compounded products;

• our ability to protect and enforce patents and other intellectual property and changes in patent law or regulations related to data package exclusivity;

• information technology system inadequacies, inadequate controls or procedures, security breaches, or operating failures;

• unauthorized access, disclosure, misappropriation, or compromise of confidential information or other data stored in our information technology systems, networks, and facilities, or those of third parties with whom we share our data and violations of data protection laws or regulations;

• issues with product supply and regulatory approvals stemming from manufacturing difficulties, disruptions, or shortages, including as a result of unpredictability and variability in demand, labor shortages, third-party performance, quality, cyber-attacks, or regulatory actions related to our and third-party facilities;

• reliance on third-party relationships and outsourcing arrangements;

• the use of artificial intelligence or other emerging technologies in various facets of our operations may exacerbate competitive, regulatory, litigation, cybersecurity and other risks;

• the impact of global macroeconomic conditions, including uneven economic growth or downturns or uncertainty, trade disruptions, international tension, conflicts, regional dependencies, or other costs, uncertainties and risks related to engaging in business globally;

• devaluations in foreign currency exchange rates or changes in interest rates and inflation;

• litigation, investigations, or other similar proceedings involving past, current, or future products or activities;

• changes in tax law and regulation, tax rates, or events that differ from our assumptions related to tax positions;

• regulatory changes and developments;

• regulatory actions regarding our operations and products;

• regulatory compliance problems or government investigations;

• actual or perceived deviation from environmental-, social-, or governance-related requirements or expectations;

• asset impairments and restructuring charges; and

• changes in accounting and reporting standards.

Investors should also carefully read the factors described under Item 1A, "Risk Factors" in this Annual Report on Form 10-K for a description of certain risks that could, among other things, cause our actual results to differ from those expressed in forward-looking statements. Investors should understand that it is not possible to predict or identify all such factors and should not consider the risks described above and under Item 1A, "Risk Factors" to be a complete statement of all potential risks and uncertainties.

All forward-looking statements speak only as of the date of this Annual Report and are expressly qualified in their entirety by the risk factors and cautionary statements included in this Annual Report. Except as is required by law, we expressly disclaim any obligation to publicly release any revisions to forward-looking statements to reflect events after the date of this Annual Report.
