Forward-Looking Statements

This communication contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding mandates, the future, business plans and other statements that are not historical in nature. These statements are made on the basis of Illumina’s views and assumptions regarding future events and business performance and plans as of the time the statements are made. These forward-looking statements may be accompanied by such words as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “intend,” “may,” “plan,” “potential,” “project,” “target,” “will” and other words and terms of similar meaning. Illumina does not undertake any obligation to update these statements unless required by applicable laws or regulations, and you should not place undue reliance on forward-looking statements. Among the important factors to which our business is subject that could cause actual results to differ materially from those in any forward-looking statements are: (i) changes in the rate of growth in the markets we serve; (ii) the volume, timing and mix of customer orders among our products and services; (iii) our ability to adjust our operating expenses to align with our revenue expectations; (iv) our ability to manufacture robust instrumentation and consumables; (v) the success of products and services competitive with our own; (vi) challenges inherent in developing, manufacturing, and launching new products and services, including expanding or modifying manufacturing operations and reliance on third-party suppliers for critical components; (vii) the impact of recently launched or pre-announced products and services on existing products and services; (viii) our ability to modify our business strategies to accomplish our desired operational goals; (ix) our ability to realize the anticipated benefits from prior or future actions to streamline and improve our R&D processes, reduce our operating expenses and maximize our revenue growth; (x) our ability to further develop and commercialize our instruments, consumables, and products, including Galleri^™, the cancer screening test developed by GRAIL, to deploy new products, services, and applications, and to expand the markets for our technology platforms; (xi) the risks and costs associated with our ongoing inability to integrate GRAIL due to the interim measures imposed on us by the European Commission as a result of their prohibition of our acquisition of GRAIL; (xii) the risks and costs associated with the integration of GRAIL’s business if we are ultimately able to integrate GRAIL; (xiii) the risk that disruptions from the consummation of our acquisition of GRAIL and associated legal or regulatory proceedings, including related appeals, or obligations will harm our business, including current plans and operations; (xiv) the risk of incurring fines associated with the consummation of our acquisition of GRAIL and the possibility that we may be required to divest all or a portion of the assets or equity interests of GRAIL on terms that could be materially worse than the terms on which we acquired GRAIL; (xv) our ability to obtain approval by third-party payors to reimburse patients for our products; (xvi) our ability to obtain regulatory clearance for our products from government agencies; (xvii) our ability to successfully partner with other companies and organizations to develop new products, expand markets, and grow our business; (xviii) uncertainty, or adverse economic and business conditions, including as a result of slowing or uncertain economic growth, COVID-19 pandemic mitigation measures, or armed conflict; (xix) the application of generally accepted accounting principles, which are highly complex and involve many subjective assumptions, estimates, and judgments and (xx) legislative, regulatory and economic developments, together with the factors set forth in Illumina’s Annual Report on Form 10-K for the year ended January 1, 2023 under the caption “Risk Factors”, in information disclosed in public conference calls, the date and time of which are released beforehand, and in filings with the Securities and Exchange Commission (the SEC) including, among others, quarterly reports on Form 10-Q.
