Current report

This report and other documents we file with the SEC contain forward-looking statements that are based on current expectations, estimates, forecasts and projections about us, our future performance, our business, our beliefs and our management’s assumptions. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. You should carefully consider the risks and uncertainties our business faces. The risks described below are not the only ones we face. Our business is also subject to the risks that affect many other companies, such as employment relations, general economic conditions, geopolitical events and international operations. Further, additional risks not currently known to us or that we currently believe are immaterial may in the future materially and adversely affect our business, operations, liquidity and stock price.

Current report

China’s Ministry of Commerce has added Illumina to its List of Unreliable Entities, which could result in fines or restrictions on our ability to do business in China and could have a material adverse effect on our revenue and results of operations.

Current report

On February 4, 2025, China’s Ministry of Commerce (MOFCOM) announced that it had added Illumina to its List of Unreliable Entities under the Provisions of the List of Unreliable Entities (the UEL Provisions). Under the UEL Provisions, potential penalties for companies placed on the List of Unreliable Entities can include monetary fines, restrictions or prohibitions on the sale of goods in China, engaging in import and export activities related to China, making investments in, or extracting investments from, China, denial of entry of our relevant personnel into China, restrictions or revocation of work permits, stay or residence status of our relevant personnel in China, or other measures.

Current report

MOFCOM has not announced what penalties will be imposed on us and we cannot currently predict the duration of our inclusion on the List of Unreliable Entities or any actions that may ultimately be taken by MOFCOM. The decision to place us on the List of Unreliable Entities and any future decision to take action to impose and enforce penalties or restrictions against us could have a material adverse effect on our revenue and results of operations. Furthermore, if, as a result of any such penalties or restrictions, we were to cease entirely or curtail operations in China, we could incur material impairment charges related to any such exit or disposal activities. Our revenue from the Greater China region, which includes China, Taiwan, and Hong Kong, was $308 million in 2024. See note 3. Revenue.

Current report

Uncertainties with respect to the development, deployment, and use of artificial intelligence in our business and products may result in harm to our business and reputation.

Current report

We have incorporated, and expect to continue to incorporate, artificial intelligence (AI) into our business activities and our product and service offerings. As with many innovations, AI presents risks and challenges that could adversely impact our business. The development, adoption, and use of AI technologies are still in their early stages and ineffective or inadequate AI development or deployment practices could result in unintended consequences. For example, AI algorithms may be flawed or may be based on datasets that are biased or insufficient. In addition, any disruption or failure in the AI functionality we incorporate into our business activities, products or services could adversely impact our business or result in delays or errors in our offerings. Conversely, any failure to successfully develop and deploy AI in our business activities, products and services could adversely affect our competitiveness (particularly if our competitors successfully deploy AI in their businesses, products, and services), and the development and deployment of AI will require additional investment and increase our costs. There also may be real or perceived social harm, unfairness, or other outcomes that undermine public confidence in the use and deployment of AI. Any of the foregoing may result in decreased demand for our products or harm to our reputation, business, financial condition, or results of operations.

Current report

The legal and regulatory landscape surrounding AI technologies is rapidly evolving and uncertain, including in the areas of intellectual property, cybersecurity, and privacy and data protection. Compliance with new or changing laws, regulations or industry standards relating to AI may impose significant costs and may limit our ability to develop, deploy, or use AI technologies. Failure to appropriately respond to this evolving landscape may result in legal liability, regulatory action, or brand and reputational harm.

Current report

On June 24, 2024, we completed the separation of GRAIL into a separate, independent publicly traded company. As of September 6, 2024, all previously disclosed regulatory proceedings in the United States and European Union related to our acquisition of GRAIL (the Acquisition) have come to an end. Litigation, regulation, and other proceedings related to or resulting from the Acquisition have resulted in operational restrictions and increased costs and could result in similar additional future consequences or further result in loss of revenues.

Current report

As previously disclosed, the Acquisition was subject to various legal challenges, including by the FTC and European Commission. As a result, we have been a party to a number of regulatory and administrative proceedings regarding the Acquisition.

Current report

The Spin-Off could result in substantial tax liability.

Current report

We received a private letter ruling from the Internal Revenue Service (the IRS) and a written opinion of tax counsel substantially to the effect that, for U.S. federal income tax purposes, the Spin-Off and certain related transactions qualified for non-recognition of gain and loss under Sections 355 and 368 of the U.S. Internal Revenue Code of 1986, as amended. If the factual assumptions or representations made in the request for the private letter ruling prove to have been inaccurate or incomplete in any material respect, then we will not be able to rely on the ruling. Furthermore, the IRS does not rule on whether a distribution such as the Spin-Off satisfies certain requirements necessary to obtain tax-free treatment under Section 355 of the Code. The private letter ruling was based on representations by us and GRAIL that those requirements were satisfied, and any inaccuracy in those representations could invalidate the ruling.

Current report

Additionally, the opinion of tax counsel relied on, among other things, the continuing validity of the private letter ruling and various assumptions and representations as to factual matters made by GRAIL and us which, if inaccurate or incomplete in any material respect, would jeopardize the conclusions reached by such counsel in its opinion. The opinion is not binding on the IRS or the courts, and there can be no assurance that the IRS or the courts would not challenge the conclusions stated in the opinion or that any such challenge would not prevail. If, notwithstanding the private letter ruling and opinion of tax counsel, the IRS determines that the Spin-Off and certain related transactions did not qualify for tax-free treatment for U.S. federal income tax purposes, the resulting tax liability to the Company and its shareholders could be substantial.

Current report

Following the Spin-Off, we remain the obligor on the contingent value rights (the CVRs) we issued in connection with the GRAIL Acquisition.

Current report

Following the Spin-Off, we remain the obligor on the CVRs and, accordingly, continue to be required to record in our financial statements the estimated future liabilities associated with the CVRs. Since we no longer own GRAIL, it may be more difficult for us to estimate these future liabilities. We also may have difficulty complying with our obligations with respect to the CVRs if we are unable to obtain timely and accurate information from GRAIL.

Current report

Changes in, or failure to comply with, competition laws could adversely affect our business, financial condition, or results of operations.

Current report

Governments are actively enforcing competition laws and regulations, and some jurisdictions also allow competitors or consumers to assert claims of anti-competitive conduct. U.S. and foreign antitrust authorities have previously brought enforcement actions and may continue to scrutinize our business (see note 9. Legal Proceedings). Regulators have been asserting expansive and sometimes novel interpretations of the scope of existing competition laws, which reduces predictability with respect to compliance. Further, any new requirements or restrictions, or proposed requirements or restrictions, could result in adverse publicity or fines, whether or not valid or subject to appeal.

Current report

Governmental agencies and regulators may, among other things, prohibit future acquisitions, divestitures, or combinations we seek to make, impose significant fines or penalties, require divestiture of certain assets, or impose other restrictions that limit or require us to modify our operations, including limitations on our contractual relationships with customers or restrictions on our pricing policies. Such rulings or uncertainty regarding regulatory interpretations of industry business practices may alter the way in which we do business and, therefore, may continue to increase our costs or liabilities or reduce demand for our products, which could adversely affect our business, financial condition, or results of operations.

Current report

Antitrust enforcement agencies (including the U.S. Department of Justice (DOJ) and the FTC and their non-U.S. equivalents) may continue to closely scrutinize pricing policies or merger activity, with a particular focus on the healthcare sector, and there can be no assurance that our pricing policies or proposed, completed, or future mergers, acquisitions, and divestitures will not be the subject of an investigation or enforcement action by the DOJ, the FTC, or another antitrust enforcement agency. Changes in antitrust laws globally, or in their interpretation, administration, or enforcement, may limit our future acquisitions, divestitures, operations, and growth.

Current report

In April 2024, the FDA issued the Final Rule relating to Laboratory Development Tests (LDTs). Newly developed LDT products may be subject to regulatory clearance or approval, and could result in adverse impacts to our business, financial condition, or results of operations.

Current report

For a number of years, the FDA has exercised its regulatory enforcement discretion to not regulate LDTs as medical devices if created and used within a single laboratory. On April 29, 2024, the FDA released final regulations under 21 CFR Part 809 under the Federal Food, Drug, and Cosmetic Act (FD&C Act) amending the regulations to make explicit that LDTs offered as IVDs are devices under the FD&C Act including when the manufacturer of the IVD is a laboratory (the LDT Rule).

Current report

The LDT Rule also provides that the FDA intends to exercise enforcement discretion with regard to premarket review and most quality system requirements for certain categories of IVDs, including currently marketed IVDs offered as LDTs that were first marketed prior to April 29, 2024. The FDA has included additional enforcement discretion policies within the rule for LDTs approved by the New York State’s Clinical Laboratory Evaluation Program (NYS CLEP).

Current report

The majority of revenue from products currently offered by our laboratories do not fall within the scope of the LDT Rule. With one exception, the LDTs currently offered as IVDs by our laboratories that fall within the purview of the LDT Rule are approved by NYS CLEP and were first marketed prior to the release of the LDT Rule.

Current report

We cannot predict the specifics of how the FDA intends to implement the Final Rule and uncertainties remain as to whether and how newly developed LDT products that are now require regulatory clearance or approval may impact our business, financial condition, or results of operations.

Previous report

Our business is subject to various risks, including those described below. In addition to the other information included in this report, the following issues could adversely affect our operating results or our stock price.

Previous report

Our acquisition of GRAIL remains subject to ongoing legal and regulatory proceedings in the United States and in the European Union. On December 17, 2023, we announced that we will divest GRAIL. Adverse decisions by the EU and/or U.S. courts, the European Commission, the FTC and/or other governmental or regulatory authorities, that have been issued in the past or may be issued in the future, and/or other adverse consequences resulting from our decision to proceed with the completion of the acquisition, have resulted in significant financial penalties, operational restrictions and increased costs, and could result in similar additional future consequences or further result in loss of revenues, implicate our existing contractual arrangements or require us to divest all or a portion of the assets or equity interests of GRAIL on terms that are materially worse than the terms on which we acquired GRAIL, any or all of which, individually or in the aggregate, could have a material adverse effect on our business, financial condition and results of operation.

Previous report

As previously disclosed, on March 30, 2021, the FTC filed an administrative complaint alleging that our acquisition of GRAIL (the Acquisition) would violate Section 7 of the Clayton Act, as amended, 15 U.S.C. § 18. On September 1, 2022, the administrative law judge (the ALJ) ruled in favor of Illumina and found that the acquisition of GRAIL did not violate Section 7 of the Clayton Act. The FTC’s complaint counsel appealed the ALJ’s decision to the full FTC on September 2, 2022. On March 31, 2023, the FTC issued an opinion and order (the FTC Order) requiring Illumina to divest GRAIL, reversing the ALJ’s ruling. On April 5, 2023, Illumina filed a petition for review of the FTC Order in the U.S. Court of Appeals for the Fifth Circuit. On April 24, 2023, the FTC granted a motion staying in its entirety the FTC Order pending resolution of Illumina’s Fifth Circuit appeal. On December 15, 2023, the Fifth Circuit issued its opinion and order, in which the court ruled that the Commission applied the incorrect standard in assessing Illumina’s open offer contract, and on that basis vacated the FTC Order and remanded the case to the Commission for reconsideration of the effects of the open offer contract under the proper standard as described in the Fifth Circuit’s decision, and in all other respects upheld the Commission’s decision.

Previous report

As previously disclosed, on April 19, 2021, the European Commission accepted a request for referral of the Acquisition (the Referral) for European Union merger review under Article 22(1) of Council Regulation (EC) No 139/2004 (the EU Merger Regulation), which had been submitted by a Member State of the European Union. On July 13, 2022, the EU General Court ruled that the European Commission has jurisdiction to review the Acquisition under the EU Merger Regulation. On September 22, 2022, we filed an appeal in the Court of Justice of the European Union asking for annulment of the EU General Court’s decision. On December 12, 2023, the Court of Justice of the European Union held a hearing on the appeal.

Previous report

As previously disclosed, on October 29, 2021, the European Commission adopted an order imposing interim measures (the Initial Interim Measures Order), which was renewed on October 28, 2022 (subject to (x) certain operational modifications and (y) an express prohibition on Illumina selling, transferring, encumbering or otherwise disposing of GRAIL or any of GRAIL’s assets), provided that (i) we ensure that Illumina and GRAIL will continue to operate as independent legal entities that transact at arms’ length, no integration activity will take place, the day-to-day operation of GRAIL will remain the sole responsibility of GRAIL’s management and our management will have no involvement in or influence over GRAIL, (ii) we take certain supportive measures to preserve GRAIL’s viability, marketability and competitiveness, including with respect to the provision of resources to GRAIL and the retention and/or replacement of key personnel of GRAIL, (iii) subject to limited exceptions, we implement all necessary measures to ensure that Illumina does not obtain any confidential information relating to GRAIL during the hold separate period and vice versa and (iv) we appoint an independent firm as monitoring trustee to monitor our compliance with the Initial Interim Measures Order. An independent monitoring trustee has been appointed. Such hold separate arrangement, and our obligations pursuant thereto, have imposed implementation and administrative processes and additional legal, financial advisory, regulatory and other professional services costs, which have been burdensome to implement and administer, and which we expect to continue for the duration of the hold separate arrangement (in the form of transitional measures imposed on Illumina pursuant to a decision adopted by the European Commission on October 12, 2023 (the EC Divestment Decision), which replaced the New Interim Measures Order). Such burdens and additional costs, independently or together with additional burdens, costs and/or liabilities arising from such arrangement, may result in loss of revenue and other adverse effects on our business, financial condition and results of operations. Moreover, our failure to comply with the terms of the EC Divestment Decision may result in the European Commission seeking to impose fines or other penalties on us. On January 10, 2023, we filed an action with the EU General Court asking for annulment of the New Interim Measures Order. On January 20, 2023, the European Commission requested that these proceedings be stayed pending our appeal on jurisdiction.

Previous report

We submitted a filing indicating that we had no objections to the European Commission’s request, and the EU General Court stayed the proceedings on February 21, 2023.

Previous report

On September 6, 2022, the European Commission announced that it had completed its Phase II review of the Acquisition and adopted a final decision (the Prohibition Decision), which found that, in its view, our acquisition of GRAIL was incompatible with the internal market in Europe because it results in a significant impediment to effective competition. On November 17, 2022, we filed an action with the EU General Court asking for annulment of the Prohibition Decision. On October 12, 2023, the European Commission adopted the EC Divestment Decision requiring us to (among other things) divest GRAIL and imposing the transitional measures. On December 22, 2023, we filed an action with the EU General Court seeking an annulment of the EC Divestment Decision.

Previous report

On July 12, 2023, the European Commission adopted a final decision finding that we breached the EU Merger Regulation by, in its view, acquiring the possibility to exert decisive influence over GRAIL and exerting such influence during the pendency of the European Commission’s review (the Article 14(2)(b) Decision). The European Commission therefore imposed a fine on us pursuant to Article 14(2)(b) of the EU Merger Regulation of approximately €432 million, representing the maximum fine of 10% of our consolidated annual revenues for fiscal year 2022. We provided guarantees in October 2023 to satisfy the obligation in lieu of cash payment while we appeal the European Commission’s jurisdictional decision and fine decision. As of December 31, 2023, we accrued $484 million, including related foreign currency losses and accrued interest, included in accrued liabilities. In addition, the European

Previous report

Commission, the FTC and/or other governmental or regulatory authorities may seek to impose other fines, penalties, remedies or restrictions. We expect to continue to hold the assets or equity interests of GRAIL separate until the divestment of GRAIL is effected, which could result in additional costs or liabilities, loss of revenue and other adverse effects on our business, financial condition and results of operations. In addition, under applicable accounting rules, we may be required from time to time to perform interim analyses of the value of GRAIL. To the extent that the value of GRAIL on a standalone basis is less than its book value, we would be required to record an impairment on our consolidated financial statements. As previously disclosed, we recorded a goodwill impairment of $712 million related to our GRAIL reporting unit in the third quarter of 2023, primarily due to a decrease in our consolidated market capitalization and a higher discount rate selected for the fair value calculation of the GRAIL reporting unit.

Previous report

On December 17, 2023, we announced that we will divest GRAIL. The divestiture is expected to be executed through a third-party sale or capital markets transaction in accordance with the EC Divestment Decision, with the goal of finalizing the terms of the divestiture by the end of the second quarter of 2024. There can be no assurance regarding the ultimate timing of the divestiture of GRAIL. Completion of the divestiture of GRAIL will be subject to the satisfaction of certain conditions, including, approval by the European Commission and the receipt of other regulatory approvals. There can be no assurance regarding the ultimate timing of the divestiture of GRAIL. Unanticipated developments could delay, prevent or otherwise adversely affect the divestiture of GRAIL, including but not limited to disruptions in general or financial market conditions or potential problems or delays in obtaining various regulatory clearances.

Previous report

We are subject to various uncertainties and restrictions while the Acquisition remains subject to ongoing regulatory and legal review and proceedings related thereto, including the EC Divestment Decision, that could adversely affect our business, financial condition and results of operations.

Previous report

During the period in which the Acquisition remains subject to ongoing regulatory and legal review and proceedings related thereto, it is possible that customers, suppliers, commercial partners and/or other persons with whom we have a business relationship may elect to delay or defer certain business decisions or decide to seek to terminate, change or renegotiate their relationships with us because of the Acquisition or the various uncertainties related to the ongoing review of the Acquisition, other legal and regulatory proceedings, and/or the hold separate arrangement required by the EC Divestment Decision, which could significantly reduce the expected benefits of the Acquisition and/or negatively affect our revenues, earnings and cash flows, and the market price of our common stock, regardless of the ultimate outcome of such review and proceedings. Uncertainty about the effects of the Acquisition (and about the related regulatory and judicial review process) on employees may impair our ability to attract, retain and motivate key personnel while the Acquisition remains subject to ongoing regulatory and legal review and proceedings, and for a period of time thereafter. If key employees depart because of these or other issues, we and GRAIL may have to incur additional and significant costs in identifying, hiring and retaining replacements for departing employees and may lose significant expertise and talent. Matters relating to the Acquisition (including the regulatory and legal review and proceedings related thereto and the hold separate arrangement required by the EC Divestment Decision) require substantial commitments of time and resources by Illumina management and personnel and will continue in the future, which otherwise would have been devoted to day-to-day operations and other opportunities that may have been beneficial to us. We will also incur significant costs related to the ongoing review and proceedings related to the Acquisition (including to comply with the hold separate obligations required by the EC Divestment Decision). These costs are substantial and include financial advisory, legal, monitoring trustee, and accounting costs.

Previous report

The market price of our common stock may decline as a result of the Acquisition and the final outcomes of the regulatory and judicial reviews thereof.

Previous report

The market price of our common stock may decline as a result of the Acquisition and the final outcomes of the regulatory and judicial reviews thereof, and holders of our common stock could see a decrease in the value of their investment in our common stock, if, among other things, we are unable to achieve the expected growth in earnings, or if the anticipated benefits, including synergies, cost savings, innovation and operational efficiencies, from the Acquisition are not realized, or if the Acquisition and integration-related costs related to the Acquisition are greater than expected, or if, as a result of unfavorable outcomes of regulatory and judicial proceedings, we are subject to fines, penalties, restrictions or remedies, including divestiture remedies. The market price of our common stock may also decline if we do not achieve the anticipated benefits of the Acquisition as rapidly or to the extent expected by financial or industry analysts or if the effects of the Acquisition on our financial position, results of operations or cash flows are not otherwise consistent with the expectations of financial or industry analysts. In addition, some former GRAIL stockholders may decide not to continue to hold the shares of our common stock they receive as a result of the Acquisition, and any such sales of our common stock could have the effect of depressing their market price. Moreover, general fluctuations in stock markets could have a material adverse effect on the market for, or liquidity of, our common stock, regardless of our actual operating performance.

Previous report

If the FDA requires in the future that any of our LDT products be subject to regulatory clearance or approval, our business, financial condition, or results of operations could be adversely affected.

Risks Relating to Research, Development, Marketing, and Sales of Products and Services

Current wording

Risks Relating to Our Sales of Products and Services, Marketing and Research and Development

Previous wording

The usefulness of our technologies depends in part upon the availability of genetic data and its usefulness in clinical, research, and consumer applications. We are focusing on markets for analysis of genetic variation or biological function, namely sequencing, genotyping, and gene expression profiling. These markets are relatively new and emerging, and they may not develop as quickly as we anticipate, or reach what we expect to be their full potential. Other methods of analysis of genetic variation and biological function may emerge and displace the methods we are developing. In addition, a reduction or delay in research and development budgets and government funding may adversely affect our business. For example, changes in the regulatory environment affecting life sciences and pharmaceutical companies, and budgetary pressures resulting in reduced allocations to government agencies that fund research and development activities, such as the U.S. National Institute of Health, or NIH, could adversely affect our business or results of operations.

Previous wording

We compete with third parties that design, manufacture, and market products and services for analysis of genetic variation and biological function and other applications using a wide range of technologies. In some cases, we compete for the resources our customers allocate for purchasing a wide range of sequencing and non-sequencing products, some of which are complementary or adjacent to our own but not directly competitive; in other cases, our products face direct competition as customers choose among sequencing and non-sequencing products that are designed to address the same use case or answer the same biological question. For example, complementary third-party sequencing technologies address use cases to which our products are not well suited. If we are unable to develop or acquire new technologies that address these complementary sequencing applications, our rate of growth and our ability to grow the overall market for sequencing could be adversely affected.

Current wording

We compete with third parties that design, manufacture, and market products and services for analysis of genetic variation and biological function and other applications using a wide range of technologies. We have faced, and expect to continue to face, increased pricing pressure from competitors who offer sequencing products and we have experienced lengthened sales cycles with many customers due to competition. In some cases, we compete for the resources our customers allocate for purchasing a wide range of sequencing and non-sequencing products, some of which are complementary or adjacent to our own but not directly competitive; in other cases, our products face direct competition as customers choose among sequencing and non-sequencing products that are designed to address the same use case or answer the same biological question. For example, complementary third-party sequencing technologies address use cases to which our products are not as well suited. If we are unable to develop or acquire new technologies that address these complementary sequencing applications, our rate of growth and our ability to grow the overall market for sequencing could be adversely affected.

Previous wording

If defects are discovered in our products, we may incur additional unforeseen costs, our products may be subject to recalls, customers may not purchase our products, our reputation may suffer, and ultimately our sales and operating earnings could be negatively impacted.

Current wording

In the past, defects have been discovered in our products, as a result of which we have incurred costs and our products have been subject to recalls. If defects are discovered in our products in the future, we may incur additional unforeseen costs, our products may be subject to recalls, customers may not purchase our products, our reputation may suffer, and ultimately our sales and operating earnings could be negatively impacted.

Previous wording

Our products incorporate complex, precision-manufactured mechanical parts, electrical components, optical components, and fluidics, as well as computer software and complex surface chemistry, biochemistry and reagents, any of which may contain or result in errors or failures, especially when first introduced. In the course of conducting our business, we must adequately address quality issues associated with our products and services, including defects in our engineering, design, and manufacturing processes, as well as defects in third-party components included in our products. In addition, new products or enhancements may contain undetected errors or performance problems that, despite testing, are discovered only after commercial shipment. Defects or errors in our products may discourage customers from purchasing our products. The costs incurred in correcting any defects or errors may be substantial and could adversely affect our operating margins. Identifying the root cause of quality issues, particularly those affecting reagents and third-party components, may be difficult, which increases the time needed to address quality issues as they arise, and increases the risk that similar problems could recur. Because our products are designed to be used to perform complex genomic analysis, we expect that our customers will have an increased sensitivity to such defects. If we do not meet applicable regulatory or quality standards, our products may be subject to recall, and, under certain circumstances, we may be required to notify applicable regulatory authorities about a recall. If our products are subject to recall or shipment holds, our reputation, business, financial condition, or results of operations could be adversely affected.

Current wording

Our products incorporate complex, precision-manufactured mechanical parts, electrical components, optical components, and fluidics, as well as computer software and complex surface chemistry, biochemistry and reagents, any of which may contain or result in errors or failures, especially when first introduced. In the course of conducting our business, we must adequately address quality issues associated with our products and services, including defects in our engineering, software development, product cybersecurity, design, and manufacturing processes, as well as defects in third-party components included in our products. In addition, new products or enhancements may contain undetected errors or performance problems that, despite testing, are discovered only after commercial shipment. Defects or errors in our products have resulted in shipment holds, product recalls, negative publicity and adverse financial impacts in the past. The costs incurred in correcting any defects or errors may be substantial and could adversely affect our operating margins. Identifying the root cause of quality issues, particularly those affecting reagents and third-party components, may be difficult, which increases the time needed to address quality issues as they arise, and increases the risk that similar problems could recur. Because our products are designed to be used to perform complex genomic analysis and our instruments can be, and often are, connected to the internet, which presents product cybersecurity risk, we expect that our customers will have an increased sensitivity to such defects. If we do not meet applicable regulatory or quality standards, our products may be, and in the past have been, subject to recall, and, under certain circumstances, we may be required to, and have in the past been required to, notify applicable regulatory authorities about a recall. Quality issues may also result in, and have in the past resulted in, additional regulatory and governmental scrutiny. If our products are subject to recall or shipment holds, our reputation, business, financial condition, or results of operations could be adversely affected.

We have experienced and might continue to experience negative impacts on our stock price. We cannot predict what other adverse consequences to, among other things, our reputation, our relationships with governmental or regulatory authorities, or our ability to successfully complete future transactions, our ability to attract, retain and motivate customers, key personnel and those with whom we conduct business may result.

Current wording

On June 24, 2024, we completed the separation (the Spin-Off) of GRAIL into a separate, independent publicly traded company as described in note 2. GRAIL Spin-Off within the Consolidated Financial Statements. We incurred significant costs to complete the Spin-Off, including significant legal, financial advisory, regulatory and other professional services fees and additional expenses, and assumed certain liabilities in connection therewith. The Spin-Off also may result in loss of revenue and other adverse effects on our business, financial condition and results of operations. In addition, we have experienced and might continue to experience negative impacts on our stock price. We cannot predict what other adverse consequences to, among other things, our reputation, our relationships with governmental or regulatory authorities, or our ability to successfully complete future transactions, our ability to attract, retain and motivate customers, key personnel and those with whom we conduct business may result.

Furthermore, we have and may continue to become subject to stockholder inspection demands under Delaware law, investigations initiated by regulators and law firms, and derivative or other similar litigation that can be expensive, divert management attention and human and financial capital to less productive uses and result in potential reputational damage. The GRAIL acquisition and subsequent litigation resulted in (i) the announcement of an investigation by the SEC and others by law firms of possible securities law violations; (ii) stockholder inspection demands seeking to investigate possible breaches of fiduciary duties, corporate wrongdoing or a lack of independence of the members of the Board; (iii) the filing of three securities class actions in the United States District Court for the Southern District of California: Kangas v. Illumina, Inc. et al., Roy v. Illumina, Inc. et al. and Louisiana Sheriffs’ Pension & Relief Fund v. Illumina, Inc. et al; (iv) the filing of two securities class actions in the Superior Court of the State of California, County of San Mateo: Loren Scott Mar v. Illumina, et al. and Scott Zerzanek v. Illumina, Inc. et al.; and (v) the filing of a stockholder derivative and class action complaint captioned Icahn Partners LP, et al. v. deSouza, et al.. The Icahn Partners LP, et al. v. deSouza, et al. complaint, purportedly brought on behalf of Illumina and public holders of Illumina’s common stock, was filed in the Delaware Court of Chancery against certain current and former directors (including our former Chief Executive Officer). We are named as a nominal defendant in the complaint. The lawsuit alleges the named directors breached their fiduciary duties by knowingly causing Illumina to unlawfully close the GRAIL acquisition, concealing material facts related to the GRAIL acquisition and making inadequate disclosures. See note“8. Legal Proceedings” within the Consolidated Financial Statements section of this report for further details. In the event that any of the matters described above result in one or more adverse judgments or settlements, we may experience an adverse impact on our financial condition, results of operations or stock price.

The Prohibition Decision, the EC Divestment Decision, and any order or decision by the FTC or any other governmental or regulatory authority pursuant to which Illumina is required to divest GRAIL (an FTC Divestment Decision), if implemented once final and non-appealable or during the pendency of the applicable appeals proceedings, and our obligations pursuant thereto, have imposed in the past and may impose in the future significant costs and additional liabilities on us, including significant legal, financial advisory, regulatory and other professional services fees and additional expenses, and may result in loss of revenue and other adverse effects on our business, financial condition and results of operations. Such adverse effects could include divesting GRAIL on terms that are materially worse than the terms on which we acquired GRAIL. Furthermore, we may not be able to direct the timing, structure or financial terms of such divestment, which could result in negative financial or tax consequences. For example, we are unlikely to be able to, in a sale of GRAIL, effect such sale in a non-taxable transaction and so would incur significant tax liabilities attributable to the recognition of taxable gain equal to the difference between (i) the fair market value of any consideration received and (ii) our tax basis in GRAIL (which tax basis is currently estimated to be between zero and $500 million). In addition, any such divestment will likely implicate certain provisions in our third-party contracts and other agreements, including our obligations with respect to the contingent value rights (the CVRs) issued by us as part of the Acquisition. We may be unable to fully discharge our obligations with respect to the CVRs in connection with any such divestiture, and/or such divestiture may result in a change in obligor on the CVRs. Moreover, the business of GRAIL may be adversely affected by any such divestment, which could adversely affect the market value of the CVRs. The EC Divestment Decision requires us to ensure that GRAIL has access to sufficient funds to cover at least 2.5 years of operations according to its latest long-range plan.

Current wording

The Spin-Off could adversely affect the market value of the CVRs.

Previous wording

Our products, if used for the diagnosis of disease, could be subject to government regulation, and the regulatory approval and maintenance process for such products may be expensive, time-consuming, and uncertain both in timing and in outcome.

Current wording

Our products, if used for the diagnosis of disease, could be subject to government regulation, and the regulatory approval and maintenance process for such products may be expensive, time-consuming, and uncertain both in timing and in outcome. Since our strategy includes an emphasis on increasing our participation in clinical markets, we will be increasingly exposed to these risks.

Previous wording

Our products are not subject to FDA clearance or approval if they are not intended to be used for the diagnosis, treatment or prevention of disease. However, as we expand our product line to encompass products that are intended to be used for the diagnosis of disease, such as our FDA-regulated MiSeqDx, certain of our products will become subject to regulation by the FDA, or comparable international agencies, including requirements for regulatory clearance or approval of such products before they can be marketed. Such regulatory approval processes or clearances may be expensive, time-consuming, and uncertain, and our failure to obtain or comply with such approvals and clearances could have an adverse effect on our business, financial condition, or operating results. In addition, changes to the current regulatory framework, including the imposition of additional or new regulations, could arise at any time during the development or marketing of our products, which may negatively affect our ability to obtain or maintain FDA or comparable regulatory approval of our products, if required.

However, as we implement our strategy to increase our participation in clinical markets by expanding our product line to encompass products that are intended to be used for the diagnosis of disease, such as our FDA-regulated MiSeqDx and NextSeq550Dx, certain of our products will become subject to regulation by the FDA, or comparable international agencies, including requirements for regulatory clearance or approval of such products before they can be marketed. Such regulatory approval processes or clearances may be expensive, time-consuming, and uncertain, and our failure to obtain or comply with such approvals and clearances could have an adverse effect on our business, financial condition, or operating results. Our failure to obtain such clearance or approval in a timely manner, or our competitors’ success in obtaining clearance or approval before we do for products that are competitive with our planned offerings, may result in material adverse business consequences because the investment and time required to seek and obtain clearance or approval for clinical products are substantial. In addition, changes to the current regulatory framework, including the imposition of additional or new regulations, could arise at any time during the development or marketing of our products, which may negatively affect our ability to obtain or maintain FDA or comparable regulatory approval of our products, if required. Diagnostic products are regulated as medical devices by the FDA and comparable international agencies and may require either clearance from the FDA following the 510(k) pre-market notification process or pre-market approval from the FDA, in each case prior to marketing. Obtaining the requisite regulatory approvals can be expensive and may involve considerable delay. If we fail to obtain, or experience significant delays in obtaining, regulatory approvals for diagnostic products that we develop, we may not be able to launch or successfully commercialize such products in a timely manner, or at all.

Previous wording

Certain of our diagnostic products are currently available through laboratories that are certified under the Clinical Laboratory Improvements Amendments (CLIA) of 1988. These products are commonly called “laboratory developed tests,” or LDTs. For a number of years, the FDA has exercised its regulatory enforcement discretion not to regulate LDTs as medical devices if created and used within a single laboratory. However, the FDA has been reconsidering its enforcement discretion policy and has commented that regulation of LDTs may be warranted because of the growth in the volume and complexity of testing services utilizing LDTs. We cannot predict the nature or extent of the FDA's final guidance or regulation of LDTs, in general, or with respect to our LDTs, in particular. If the FDA requires in the future that LDT products are subject to regulatory clearance or approval, our business, financial condition, or results of operations could be adversely affected.

Our success depends, in part, on the continued and uninterrupted performance of our IT systems, which are used extensively in virtually all aspects of our business. IT systems may be vulnerable to damage from a variety of sources, including telecommunications or network failures, power loss, natural disasters, human acts, terrorist attacks, computer viruses, computer denial-of-service attacks, ransomware attacks, unauthorized access to customer or employee data or company trade secrets, and other attempts to harm our systems. Certain of our systems are not redundant, and our disaster recovery planning is not sufficient for every eventuality. Further, the emerging development of artificial intelligence could create unforeseen, more sophisticated attacks. Despite any precautions we may take, such problems could result in, among other consequences, disruption of our operations, which could harm our reputation and financial results.
