By their nature, forward-looking statements involve risks and uncertainty because they relate to events and depend on circumstances that will occur in the future, and there are many factors that could cause actual results and developments to differ materially from those expressed or implied by these forward-looking statements. Forward-looking statements include, among other things, statements about the potential benefits of the proposed acquisition of ChemoCentryx by Amgen (the “proposed transaction”); the prospective performance and outlook of ChemoCentryx’s business, performance and opportunities; any potential strategic benefits, synergies or opportunities expected as a result of the proposed transaction; the ability of the parties to complete the proposed transaction and the expected timing of completion of the proposed transaction; as well as any assumptions underlying any of the foregoing.

These statements are not guarantees of future performance and they involve certain risks, uncertainties and assumptions that are difficult to predict. We caution you that actual outcomes and results may differ materially from what is expressed, implied or forecasted by our forward-looking statements. There can be no guarantee that the proposed transaction will be completed, or that it will be completed as currently proposed, or at any particular time. Neither can there be any guarantee that Amgen or ChemoCentryx will achieve any particular future financial results, or that Amgen will be able to realize any of the potential strategic benefits, synergies or opportunities as a result of the proposed acquisition. In particular, our expectations could be affected by, among other things: the risk that the proposed transaction may not be completed in a timely manner or at all; the possibility that competing offers or acquisition proposals for ChemoCentryx will be made; the possibility that required regulatory, stockholder or other approvals or other conditions to the consummation of proposed transaction may not be satisfied on a timely basis or at all (and the risk that such approvals may result in the imposition of conditions that could adversely affect Amgen or ChemoCentryx or the expected benefits of the proposed transaction); regulatory actions or delays or government regulation generally, including potential regulatory actions or delays relating to the completion of the potential transaction; the occurrence of any event, change or other circumstance that could give rise to the right of Amgen or ChemoCentryx to terminate the definitive merger agreement governing the terms and conditions of the proposed transaction; effects of the announcement, pendency or consummation of the proposed transaction on ChemoCentryx’s ability to retain and hire key personnel, its ability to maintain relationships with its customers, suppliers and others with whom it does business, its business generally or its stock price; risks related to the diversion of management’s attention from ongoing business operations and opportunities; the risk that stockholder litigation in connection with the proposed transaction may result in significant costs of defense, indemnification and liability; the potential that the strategic benefits, synergies or opportunities expected from the proposed transaction may not be realized or may take longer to realize than expected; the successful integration of ChemoCentryx into Amgen subsequent to the closing of the proposed transaction and the timing, difficulty and cost of such integration; the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; and other risks and factors referred to from time to time in Amgen’s and ChemoCentryx’s filings with the SEC, including Amgen’s Annual Report on Form 10-K for the year ended December 31, 2021 and subsequent Quarterly Reports on Form 10-Q and ChemoCentryx’s Annual Report on Form 10-K for the year ended December 31, 2021 and subsequent Quarterly Reports on Form 10-Q, including those related to the uncertainties inherent in the research and development of new and existing healthcare products, including clinical and regulatory developments and additional analysis of existing clinical data; our ability to obtain or maintain proprietary intellectual property protection; safety, quality or manufacturing issues or delays; changes in expected or existing competition; and domestic and global trends toward health care cost containment, including government, payor and general public pricing and reimbursement pressures. The effects of the COVID-19 pandemic may give rise to risks that are currently unknown or amplify the risks associated with many of these factors.
