Consideration Regarding Forward-Looking Statements
This Quarterly Report on Form 10-Q contains, and our officers and representatives may from time to time make, “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Words such as: “anticipate,” “intend,” “plan,” “goal,” “seek,” “believe,” “continue,” “project,” “estimate,” “expect,” “strategy,” “future,” “likely,” “may,” “potential,” “predict,” “should,” “will,” or similar words or phrases, or the negatives of these words, may identify forward-looking statements, but the absence of these words does not necessarily mean that a statement is not forward looking. Examples of forward-looking statements include, among others, statements we make regarding:
our expectations as to our future financial performance, results of operations, or other operational results or metrics;
our expectations regarding the launch of new products or services;
the benefits that we expect will result from our business activities and certain transactions we have completed, or may complete, such as product introductions, increased revenue, decreased expenses, and avoided expenses and expenditures;
our expectations of the effect on our financial condition of claims, litigation, contingent liabilities, and governmental investigations, proceedings, and regulations;
our strategies or expectations for product development, market position, financial results, and reserves;
our ability to successfully implement cost reduction plans in a timely manner and the possibility that costs associated with our cost reduction plans are greater than we anticipate;
our expectations regarding the outcome of the legal and regulatory proceedings, including any related appeals, related to our acquisition of GRAIL, Inc. (GRAIL) and other actions that may be taken or pursued by the European Commission, the U.S. Federal Trade Commission (FTC) and/or other governmental or regulatory authorities in connection with such acquisition;
the interimtransitional measures order imposed by the European Commission, the duration and impact of such ordermeasures on Illumina and GRAIL, and the appointment of a monitoring trustee to monitor our compliance with such order;measures;
the prohibition decision adopted by the European Commission on September 6, 2022 (the Prohibition Decision), informing us of its decision to prohibit our acquisition of GRAIL, and the public statements made by the European Commission in connection with such decision that indicate that a subsequent decision is likely to be adopted by the European Commission that willon October 12, 2023 requiring us to (among other things) divest GRAIL and imposing transitional measures (the EC Divestment Decision);
the opinion and order issued by the FTC on March 31, 2023 (the FTC Order), requiring us to divest GRAIL;GRAIL and to hold GRAIL separate through the completion of the divestiture;
our expectations regarding the integration of any acquired technologies with our existing technology;Article 14(2)(b) fine imposed by the European Commission on July 12, 2023; and
other expectations, beliefs, plans, strategies, anticipated developments, and other matters that are not historical facts.
Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations, and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy, and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following:
the impact to our business and operating results caused by the COVID-19 pandemic;
our expectations and beliefs regarding prospects and growth for our business and the markets in which we operate;

Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Interim financial results are not necessarily indicative of results anticipated for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes included in the Annual Report on Form 10-K for the fiscal year ended January 2, 2022,1, 2023, from which the prior year balance sheet information herein was derived. The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expense, and related disclosure of contingent assets and liabilities. Though the impact of the COVID-19 pandemic, to our businessthe armed conflict between Russia and operating results presentsUkraine, and macroeconomic factors such as inflation, exchange rates and concerns about an economic downturn present additional uncertainty, we continue to use the best information available to form our critical accounting estimates. Actual results could differ from those estimates.
The unaudited condensed consolidated financial statements include our accounts, our wholly-owned subsidiaries, and majority-owned or controlled companies. All intercompany transactions and balances have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the results for the interim periods presented.

Significant Accounting Policies
During YTD 2022,2023, there were no changes to our significant accounting policies as described in our Annual Report on Form 10-K for the fiscal year ended January 2, 2022, except as described in Recently Adopted Accounting Pronouncements below.
Recently Adopted Accounting Pronouncements
In August 2020,1, 2023, with the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). The new standard reduces the number of accounting models for convertible debt instruments, amends the accounting for certain contracts in an entity’s own equity, and modifies how certain convertible instruments and contracts that may be settled in cash or shares impact the calculation of diluted earnings per share. Specifically, the guidance removes certain accounting models that separate the embedded conversion features from the host contract for convertible instruments and requires the useexception of the if-convertedfollowing for income taxes:
Historically, we calculated the provision/(benefit) for income taxes for interim periods utilizing an estimated annual effective tax rate applied to the income/(loss) for the reporting period, except in Q2 2023 when a year-to-date effective tax rate method to calculate diluted earnings per share. was utilized.We adopteddetermined the standard on itsestimated annual effective datetax rate method would provide a more reliable estimate of the provision for income taxes for Q3 2023 and YTD 2023 since minor changes in the first quarter of 2022 using a modified retrospective approach by recognizing a cumulative-effect adjustment to retained earnings on January 3, 2022. We didestimated income/(loss) before income taxes would not restate prior periods. As a result ofin significant changes in the adoption, we increased our convertible senior notes and retained earnings, on January 3, 2022, by $43 million and $61 million, respectively, and decreased our deferredestimated annual effective tax liabilities, included in other long-term liabilities on the condensed consolidated balance sheets, and additional paid-in capital by $11 million and $93 million, respectively. Interest expense recognized in future periods will be reduced as a result of accounting for our convertible senior notes as a single liability measured at amortized cost. See note “4. Debt” for additional details on the adoption of ASU 2020-06.rate.
Earnings (Loss)Loss per Share
Basic earnings (loss)loss per share is computed based on the weighted average number of common shares outstanding during the period. Diluted earnings (loss)loss per share is computed based on the sum of the weighted average number of common shares and potentially dilutive common shares outstanding during the period. In loss periods, basic and diluted loss per share are identical since the effect of potentially dilutive common shares is antidilutive and therefore excluded.
Potentially dilutive common shares consist of shares issuable under convertible senior notes and equity awards. On January 3, 2022, we adopted ASU 2020-06. As a result, beginning in Q1 2022, weWe utilize the if-converted method to calculate the impact of convertible senior notes on diluted earnings (loss)loss per share. Prior to the adoption of ASU 2020-06, we applied the treasury stock method when calculating the potential dilutive effect, if any, of convertible senior notes which we intended to settle or have settled in cash the principal outstanding. Under the treasury stock method, convertible senior notes would have a dilutive impact when the average market price of our common stock exceeded the applicable conversion price of the respective notes. Potentially dilutive common shares from equity awards are determined using the average share price for each period under the treasury stock method. In addition, proceeds from exercise of equity awards and the average amount of unrecognized compensation expense for equity awards are assumed to be used to repurchase shares. In loss periods, basic loss per share and diluted loss per share are identical since the effect of dilutive potential common shares is anti-dilutive and therefore excluded.

Region includes revenue from Russia and Turkey.
Performance Obligations
We regularly enter into contracts with multiple performance obligations. These contracts are believed to be firm as of the balance sheet date. However, we may allow customers to make product substitutions as we launch new products. The timing of shipments depends on several factors, including agreed upon shipping schedules, which may span multiple quarters. Most performance obligations are generally satisfied within a short time frame, approximately three to six months, after the contract execution date. As of October 2, 2022,1, 2023, the aggregate amount of the transaction price allocated to remaining performance obligations was $974$743 million, of which approximately 88%83% is expected to be converted to revenue in the next twelve months, approximately 6%10% in the following twelve months, and the remainder thereafter.
Contract Assets and Liabilities
Contract assets, which consist of revenue recognized and performance obligations satisfied or partially satisfied in advance of customer billing, were $17$19 million and $16$17 million as of October 2, 20221, 2023 and January 2, 2022,1, 2023, respectively, and were recorded in prepaid expenses and other current assets.
Contract liabilities, which consist of deferred revenue and customer deposits, as of October 2, 20221, 2023 and January 2, 20221, 2023 were $288$315 million and $297$308 million, respectively, of which the short-term portions of $225$242 million and $234$245 million, respectively, were recorded in accrued liabilities and the remaining long-term portions were recorded in other long-term liabilities. Revenue recorded in Q3 20222023 and YTD 2022 2023included $41$43 million and $206 million, respectively, of previously deferred revenue that was included in contract liabilities as of January 2, 2022.1, 2023.

Our marketable equity securities are measured at fair value based on quoted trade prices in active markets. Our deferred compensation plan assets consist primarily of investments in life insurance contracts carried at cash surrender value, which reflects the net asset value of the underlying publicly traded mutual funds. We perform control procedures to corroborate the fair value of our holdings, including comparing valuations obtained from our investment service provider to valuations reported by our asset custodians, validating pricing sources and models, and reviewing key model inputs, if necessary.
We elected the fair value option to measure the contingent value right received from Helix. The fair value of such contingent value right, included in other assets, is derived using a Monte Carlo simulation. Estimates and assumptions used in the Monte Carlo simulation include probabilities related to the timing and outcome of future financing and/or liquidity events, assumptions regarding collectibility and volatility, and an estimated equity value of Helix. These unobservable inputs represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value.
We reassess the fair value of contingent consideration related to acquisitions on a quarterly basis. Changes in the fair value of contingent consideration subsequent to the acquisition date are recognized in selling, general and administrative expense. The contingent value rights issued as part of the GRAIL acquisition entitle the holders to receive future cash payments on a quarterly basis (Covered Revenue Payments) representing a pro rata portion of certain GRAIL-related revenues (Covered Revenues) each year for a 12-year period. As defined in the Contingent Value Rights Agreement, this will reflect a 2.5% payment right to the first $1 billion of revenue each year for 12 years. Revenue above $1 billion each year will be subject to a 9% contingent payment right during this same period. Covered Revenues for Q4 2022, Q1 2023, and Q2 2023 were $65 million in aggregate and Covered Revenues for Q4 2021, Q1 2022, and Q2 2022 were $32 million in aggregate, driven primarily by sales of GRAIL’s Galleri test. Corresponding Covered Revenue Payments relating to such periods were approximately $609,000 and $297,000 in YTD 2023 and YTD 2022, were approximately $297,000; however, pursuantrespectively. Pursuant to the Contingent Value Rights Agreement, a portion of the Covered Revenue Payments in YTD 2022 were applied to reimburse us for certain expenses. We use a Monte Carlo simulation to estimate the fair value of contingent consideration related to the GRAIL acquisition. Estimates and assumptions used in the Monte Carlo simulation include forecasted revenues for GRAIL, a revenue risk premium, a revenue volatility estimate, an operational leverage ratio and a counterparty credit spread. These unobservable inputs represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value. Changes in the fair value of contingent consideration subsequent to the acquisition date are recognized in selling, general and administrative expense in our condensed consolidated statements of operations. The fair value of our contingent consideration liability related to the GRAIL acquisition was $387$330 million and $615$412 million as of October 2, 20221, 2023 and January 2, 2022,1, 2023, respectively, of which $386$329 million and $614$411 million, respectively, was included in other long-term liabilities, with the remaining balances included in accrued liabilities.

The 2023 Convertible Notes will be convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, based on an initial conversion rate, subject to adjustment, of 2.1845 shares of common stock per $1,000$500 million aggregate principal amount of notes (which represents an initial conversion price of approximately $457.77 per share of common stock), only in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending2027 Term Notes.

At the time of issuance, the embedded conversion feature of the 2023 Convertible Notes was required to be bifurcated from the notes and accounted for as an equity instrument classified within stockholders’ equity. As a result, we recognized $126 million in additional paid-in capital in 2018, which was recorded as a debt discount and subsequently amortized to interest expense at an estimated effective rate, assuming no conversion option, of 3.7%. As of January 3, 2022, we adopted ASU 2020-06, which removed the requirement to separate the embedded conversion feature from the notes and requires the notes to be accounted for as a single liability measured at amortized cost. Accordingly, we reclassified the unamortized debt discount from additional paid-in capital to convertible senior notes in the condensed consolidated balance sheets on January 3, 2022. This resulted in an increase to our convertible senior notes and retained earnings of $43 million and $61 million, respectively, and a decrease to our deferred tax liabilities, included in other long-term liabilities, and additional paid-in capital of $11 million and $93 million, respectively.
Interest expense recognized on the 2023 Convertible Notes, which included amortization of debt issuance costs, was $1 million and $2 million in Q3 2022 and YTD 2022, respectively. Interest expense recognized on the 2023 Convertible Notes in Q3 2021 and YTD 2021 was $7 million and $21 million, respectively, which included amortization of the original debt discount and debt issuance costs.

Liability-Classified RSU
In Q1 2023, we granted RSU that were to be settled in cash if stockholder approval to increase our share reserve under the amended and restated 2015 Stock Plan was not obtained. In Q2 2023, the Company’s stockholders approved an amended and restated version of the 2015 Stock Plan and increased the maximum number of shares authorized for issuance. Upon such approval, all RSU previously accounted for as liability-classified awards, approximately 557,000 RSU, were reclassified to stockholders’ equity and accounted for prospectively as equity awards. There were no RSU liability-classified awards outstanding as of October 1, 2023.
Market-Based PSU
During YTD 2023, we granted PSU with a market condition that vest based on the Company’s relative total shareholder return (rTSR) as compared to a peer group of companies measured over a three-fiscal year performance period. Depending on the actual performance over the measurement period, an award recipient could receive up to 175% of the granted award. The grant date fair value of such awards is estimated using a Monte Carlo simulation, which includes assumptions for expected volatility, risk-free interest rate and dividend yield.

In connection with the acquisition of GRAIL, we assumed a performance-based award for which vesting is based on GRAIL’s future revenues. The award has an aggregate potential value of up to $78 million and expires, to the extent unvested, in August 2030. As of October 2, 2022,1, 2023, it was not probable that the performance conditions associated with the award will be achieved and, therefore, no share-based compensation expense, or corresponding liability, has been recognized in the condensed consolidated financial statements to-date.
Employee Stock Purchase Plan
The price at which common stock is purchased under the Employee Stock Purchase Plan (ESPP) is equal to 85% of the fair market value of the common stock on the first day of the offering period or purchase date, whichever is lower. During YTD 2022,2023, approximately 0.30.4 million shares were issued under the ESPP. As of October 2, 2022,1, 2023, there were approximately 12.812.4 million shares available for issuance under the ESPP.

In connection with the acquisition of GRAIL, we recognized, in Q3 2021, share-based compensation expense of $615 million related to the fair value of accelerated equity awards attributable to the post-combination period, of which $167 million was recorded in research and development expense and $448 million in selling, general and administrative expense.
In February 2021, we modified the metrics and reduced the maximum potential payouts for our performance stock units granted in 2019 and 2020. The PSU granted in 2019 vested on January 2, 2022 and the PSU granted in 2020 vests at the end of the three-year period ending on January 1, 2023. The modifications affected 52 employees with units granted in 2019, which resulted in total incremental share-based compensation expense of approximately $41 million, and 72 employees with units granted in 2020, which resulted in total incremental share-based compensation expense of approximately $65 million.
The assumptions used and the resulting estimate of weighted-average fair value per share for stock purchased under the ESPP during YTD 2022 were as follows:

Intangible Assets and Goodwill
We recorded a developed technology intangible asset of $23 million, with a useful life of 7 years, and a database intangible asset of $12 million, with a useful life of 7 years, as a result of an acquisition in Q2 2022. We are still finalizing the allocation of the purchase price as additional information is received to complete our analysis. We expect to finalize the valuation as soon as practicable, but no later than one year after the acquisition date.

We recorded a measurement period adjustment in Q3 2022 related to our GRAIL acquisition to decrease goodwill and increase deferred tax assets by $6 million, as a result of finalizing GRAIL’s U.S. tax returns. The measurement period adjustment was made to reflect facts and circumstances that existed as of the acquisition date. We finalized the allocation of the purchase price for the GRAIL acquisition in August 2022.
Impairment of Goodwill
We test goodwill for impairment annually, as of May, or more frequently if events or circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount. We performed our annual impairment test in Q2 2022, as of May 2022. We performed a qualitative assessment for the Core Illumina reporting unit, noting no impairment. For the GRAIL reporting unit, we performed a quantitative assessment and determined a fair value for the reporting unit using a discounted cash flow model, which included assumptions for projected cash flows and a discount rate of 16.0%. The selected discount rate was determined using a weighted average cost of capital for risk factors specific to GRAIL and other market and industry data. The estimates and assumptions used represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value. Based on the quantitative test performed, the fair value of the GRAIL reporting unit exceeded its carrying value by $700 million and no goodwill impairment was recorded in Q2 2022.
On July 13, 2022, the EU General Court ruled that the European Commission has jurisdiction to review our acquisition of GRAIL. Additionally, on September 6, 2022, the European Commission issued its decision prohibiting the acquisition. Refer to note “7. Legal Proceedings” for additional details. These decisions, along with a continued and significant decrease in the Company’s stock price and market capitalization, led us to believe that a triggering event occurred and that an interim goodwill and intangible asset impairment test was required in Q3 2022.

Based on our interim analysis, we concluded that our GRAIL reporting unit’s carrying value exceeded its estimated fair value. As a result, we recorded $3,914 million of goodwill impairment related to our GRAIL reporting unit in Q3 2022, primarily due to the negative impact of current capital market conditions and a higher discount rate selected for the fair value calculation of the GRAIL reporting unit. No impairment was recorded for our Core Illumina reporting unit, noting its fair value exceeded its carrying value by more than $30 billion.
We performed our interim goodwill impairment test using a combination of both an income and a market approach to determine the fair value of each reporting unit. The income approach utilized the estimated discounted cash flows for each reporting unit while the market approach utilized comparable company information. Estimates and assumptions used in the income approach included projected cash flows for both the GRAIL and Core Illumina reporting units and a discount rate for each reporting unit. Discount rates were determined using a weighted average cost of capital for risk factors specific to each reporting unit and other market and industry data. For the GRAIL reporting unit, the discount rate selected was 22.0%. The estimates and assumptions used in our assessment represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value. The assumptions used in our impairment analysis are inherently subject to uncertainty and we note that small changes in these assumptions could have a significant impact on the concluded value. In order to further validate the reasonableness of the fair

values concluded for our reporting units, a reconciliation to market capitalization was performed by estimating a reasonable implied control premium and other market factors.
As a result of the impairment taken in Q3 2022, the carrying value of our GRAIL reporting unit now approximates its fair value. As such, changes in our future operating results, cash flows, share price, market capitalization or discount rates, as well as future regulatory decisions related to our acquisition of GRAIL, used when conducting future goodwill impairment tests could affect the estimated fair values of our reporting units and may result in additional goodwill impairment charges in the future. We will continue to monitor events occurring or circumstances changing which may suggest that goodwill should be reevaluated during interim periods prior to the annual impairment test. As of Q3 2022, remaining goodwill allocated to the GRAIL reporting unit was $2,178 million.
In conjunction with the interim goodwill impairment test, we also evaluated the IPR&D intangible asset, assigned to the GRAIL reporting unit, for potential impairment. We performed our interim impairment test by comparing the carrying value of the IPR&D intangible asset to its estimated fair value, which was determined by the income approach, using a discounted cash flow model. Estimates and assumptions used in the income approach included projected cash flows and a discount rate. These estimates and assumptions represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value. Based on our interim impairment test, the carrying value of the IPR&D intangible asset did not exceed its estimated fair value. As a result, no impairment for the IPR&D intangible asset was recorded in Q3 2022.
We also performed a recoverability test for the definite-lived intangible assets assigned to the GRAIL reporting unit, which includes developed technology and trade name, noting no impairment in Q3 2022. Additionally, no impairment was noted for the definite-lived intangible assets assigned to our Core Illumina reporting unit.

We generally provide a one-year warranty on instruments. Additionally, we provide a warranty on consumables through the expiration date, which generally ranges from six to twelve months after the manufacture date. At the time revenue is recognized, an accrual is established for estimated warranty expenses based on historical experience as well as anticipated product performance. We periodically review the warranty reserve for adequacy and adjust the warranty accrual, if necessary, based on actual experience and estimated costs to be incurred. Warranty expense is recorded as a component of cost of product revenue.

Restructuring
In Q2 2023, we implemented a cost reduction initiative that included workforce reductions, the consolidation of certain facilities and other actions to reduce expenses, all as part of a plan to realign operating expenses while maintaining focus on our innovation roadmap and sustainable long-term growth. In Q3 2023 and YTD 2023, we recorded restructuring charges primarily consisting of asset impairment charges and employee separation costs.
A summary of the pre-tax restructuring charges are as follows:

For YTD 2023 $74 million was recorded in SG&A expense, $13 million in R&D expense, with the remainder recorded in cost of revenue.

We fully exited our i3 campus in San Diego, California in Q3 2023, which resulted in a right-of-use asset impairment of $33 million in Q3 2023 and $38 million in YTD 2023, recognized in selling, general and administrative expense. The impairment was determined by comparing the fair value of the impacted right-of-use asset to the carrying value of the asset as of the impairment measurement date. The fair value of the right-of-use asset was estimated using the discounted future cash flows method, which includes estimates and assumptions for future sublease rental rates that reflect current sublease market conditions, as well as a discount rate. The estimates and assumptions used in our assessment represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value. We also recorded $14 million in Q3 2023 and $16 million in YTD 2023 of leasehold improvement impairment, recognized in selling, general and administrative expense, related to the exit of our i3 campus. We continue to evaluate our options with respect to our campus in Foster City, California. As of October 1, 2023, we had assets, consisting primarily of right-of-use assets and leasehold improvements, related to our Foster City campus of approximately $182 million.

Goodwill and Intangible Assets
We test goodwill for impairment annually, as of May, or more frequently if events or circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount. We performed our annual impairment test in Q2 2023, as of May 2023. We performed a quantitative assessment for our two reporting units: Core Illumina and GRAIL. No impairment was recorded for either Core Illumina or GRAIL in Q2 2023.

Table of Contents

In Q3 2023, we concluded the sustained decrease in the Company’s stock price and overall market capitalization during the quarter was a circumstance indicating the fair value of a reporting unit might be less than its carrying amount that required an interim goodwill and intangible impairment test be performed.
Based on our interim assessment, we concluded that our GRAIL reporting unit’s carrying value exceeded its estimated fair value. As a result, we recorded $712 million of goodwill impairment related to our GRAIL reporting unit in Q3 2023, primarily due to a decrease in the company’s consolidated market capitalization and a higher discount rate selected for the fair value calculation of the GRAIL reporting unit. No impairment was recorded for our Core Illumina reporting unit, noting its fair value exceeded its carrying value by more than $20 billion.
We performed our impairment test using a combination of an income and a market approach to determine the fair value of each reporting unit. The income approach utilized the estimated discounted cash flows for each reporting unit, while the market approach utilized comparable company information. Estimates and assumptions used in the income approach included projected cash flows and a discount rate for each reporting unit. Discount rates were determined using a weighted average cost of capital for risk factors specific to each reporting unit and other market and industry data. For GRAIL, the selected discount rate was 24.0%. The estimates and assumptions used in our assessment represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value. The assumptions used are inherently subject to uncertainty and we note that small changes in these assumptions could have a significant impact on the concluded value. An increase of 50 to 100 basis points to the discount rate used in our assessment for GRAIL would have resulted in additional goodwill impairment of approximately $200 million to $350 million for GRAIL. In order to further validate the reasonableness of the fair values concluded for our reporting units, a reconciliation to market capitalization was performed by estimating a reasonable implied control premium and other market factors.
As a result of the impairment taken in Q3 2023, the carrying value of our GRAIL reporting unit now approximates its fair value. As such, changes in our future operating results, cash flows, share price (our share price has declined approximately 18% during the period October 1, 2023 to November 6, 2023), market capitalization or discount rates, as well as future regulatory decisions related to our acquisition of GRAIL, including the decision adopted by the European Commission on October 12, 2023 requiring us to divest GRAIL (refer to note “7. Legal Proceedings”), used when conducting future goodwill impairment tests could affect the estimated fair values of our reporting units and may result in additional impairment charges in the future. We will continue to monitor events and circumstances which may suggest that interim impairment indicators are present prior to the annual impairment test. As of October 1, 2023, remaining goodwill allocated to GRAIL was $1,466 million.
In conjunction with the interim goodwill impairment test, we also evaluated the in-process research and development (IPR&D) asset assigned to the GRAIL reporting unit for potential impairment. We performed our impairment test by comparing the carrying value of the IPR&D asset to its estimated fair value, which was determined by the income approach, using a discounted cash flow model. Estimates and assumptions used in the income approach, which represent a Level 3 measurement, included projected cash flows and a selected discount rate of 19.0%. Based on our impairment test, the carrying value of the GRAIL IPR&D asset exceeded its estimated fair value and we recorded an impairment of $109 million in Q3 2023, primarily due to a decrease in projected cash flows and a higher discount rate selected for the fair value calculation of the GRAIL IPR&D asset. As of October 1, 2023, the carrying value of the GRAIL IPR&D asset was $561 million. We also performed a recoverability test for the definite-lived intangible assets assigned to the GRAIL reporting unit, which includes developed technology and trade name, noting no impairment. No impairment was noted for Core Illumina definite-lived intangible assets.

Derivative Financial Instruments
We are exposed to foreign exchange rate risks in the normal course of business and use derivative financial instruments to partially offset this exposure. We do not use derivative financial instruments for speculative or trading purposes. Foreign exchange contracts are carried at fair value in other current assets, other assets, accrued liabilities, or other long-term liabilities, as appropriate, on the condensed consolidated balance sheets.
We use foreign exchange forward contracts to manage foreign currency risks related to monetary assets and liabilities denominated in currencies other than the U.S. dollar. These derivative financial instruments have terms of one month or less and are not designated as hedging instruments. Changes in fair value of these derivatives are recognized in other (expense) income,expense, net, along with the re-measurement gain or loss on the foreign currency denominated assets or liabilities. As of October 2, 2022,1, 2023, we had foreign exchange forward contracts in place to hedge exposures in the euro, Japanese yen, Australian dollar, Canadian dollar, Singapore dollar, Chinese Yuan Renminbi, and British pound. As of October 2, 20221, 2023 and January 2, 2022,1, 2023, the total notional amounts of outstanding forward contracts in place for these foreign currency purchases were $472$912 million and $462$485 million, respectively. On July 25, 2023, we entered into forward contracts for a total notional amount of €432 million to hedge the foreign currency exposure for the fine imposed by the European Commission on July 12, 2023.
We also use foreign currency forward contracts to hedge portions of our foreign currency exposure associated with forecasted revenue transactions. These derivative financial instruments have terms up to 24 months and are designated as cash flow hedges. Changes in fair value of our cash flow hedges are recorded as a component of accumulated other comprehensive income and are reclassified to revenue in the same period the underlying hedged transactions are recorded. Accordingly, we reclassified $16 million and $32 million to revenue in Q3 2022 and YTD 2022, respectively, and $3 million and $4 million in Q3 2021 and YTD 2021, respectively. The fair value of the foreign currency forward contracts recorded in total assets on the condensed consolidated balance sheets was $47 million and $19 million as of October 2, 2022 and January 2, 2022, respectively, of which $40 million and $19 million, respectively, was recorded within prepaid expenses and other current assets. The estimated net gains reported in accumulated other comprehensive income that are expected to be reclassified into earnings within the next 12 months are $40 million as of October 2, 2022. We regularly review the effectiveness of our cash flow hedges and consider them to be ineffective if it becomes probable that the forecasted transactions will not occur in the identified period. Changes in fair value of the ineffective portions of our cash flow hedges, if any, will beare recognized in other (expense) income,expense, net. As of October 2, 2022,1, 2023, we had foreign currency forward contracts in place to hedge exposures associated with forecasted revenue transactions denominated in the euro, Japanese yen, Australian dollar, Canadian dollar, and Canadian dollar.Chinese Yuan Renminbi. As of October 2, 20221, 2023 and January 2, 2022,1, 2023, the total notional amounts of outstanding cash flow hedge contracts in place for these foreign currency purchases were $419$663 million and $450$425 million, respectively. We reclassified $5 million and $9 million to revenue in Q3 2023 and YTD 2023, respectively, and $16 million and $32 million in Q3 2022 and YTD 2022, respectively. As of October 1, 2023, the fair value of the foreign currency forward contracts recorded in total assets and total liabilities was $27 million and $1 million, respectively. As of January 1, 2023, the fair value of the foreign currency forward contracts recorded in total assets and total liabilities was $8 million and $6 million, respectively. The estimated net gains reported in accumulated other comprehensive income that are expected to be reclassified into earnings within the next 12 months are $22 million as of October 1, 2023.
7. LEGAL PROCEEDINGS
We are involved in various lawsuits and claims arising in the ordinary course of business, including actions with respect to intellectual property, employment, and contractual matters. In connection with these matters, we assess, on a regular basis, the probability and range of possible loss based on the developments in these matters. A liability is recorded in the condensed consolidated financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly subjective and requires judgments about future events. We regularly review outstanding legal matters to determine the adequacy of the liabilities accrued and related disclosures in consideration of many factors, which include, but are not limited to, past history, scientific and other evidence, and the specifics and status of each matter. We may change our estimates if our assessment of the various factors changes and the amount of ultimate loss may differ from our estimates, resulting in a material effect on our business, financial condition, results of operations, and/or cash flows.

Acquisition of GRAIL
Our acquisition of GRAIL remains subject to ongoing legal and regulatory proceedings in the United States and in the European Union.

Table of Contents

On March 30, 2021, the U.S. Federal Trade Commission (the FTC) filed an administrative complaint and a motion for a preliminary injunction in the United States District Court for the District of Columbia. In both actions, the FTC alleged that our acquisition of GRAIL would violate Section 7 of the Clayton Act, as amended, 15 U.S.C. § 18. We filed an answer to the FTC’s complaint in federal district court on April 6, 2021, and in the administrative court on April 13, 2021. On April 20, 2021, the United States District Court for the District of Columbia granted our motion to transfer venue to the United States District Court for the Southern District of California. On May 28, 2021, the district court granted the FTC’s motion to dismiss the complaint without prejudice. The administrative trial commenced on August 24, 2021. 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. In the decision, the ALJ found that the FTC’s complaint counsel had failed to prove its prima facie case that Illumina’s acquisition of GRAIL would result in harm to competition in a putative market for multi-cancer early detection (MCED) tests. The FTC’s complaint counsel appealed the ALJ’s decision to the full FTC on September 2, 2022. The appeal was fully briefed as of November 10, 2022 and oral argument occurred on October 4, 2022,December 13, 2022. On March 31, 2023, the FTC’s complaint counselFTC 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 openingentirety the FTC Order pending resolution of Illumina’s Fifth Circuit appeal. The appeal brief.was fully briefed as of August 16, 2023 and oral argument occurred on September 12, 2023. We intend to continue to vigorously defend against the FTC action.
On April 19, 2021, the European Commission accepted a request for a referral of the GRAIL acquisition for European Union merger review, submitted by a Member State of the European Union (France), and joined by several other Member States (Belgium, Greece, Iceland, the Netherlands and Norway), under Article 22(1) of Council Regulation (EC) No 139/2004 (the EU Merger Regulation). The European Commission had never solicited referrals to take jurisdiction over an acquisition of a U.S. company that had no revenue in Europe. On April 29, 2021, we filed an action in the General Court of the European Union (the EU General Court) asking for annulment of the European Commission’s assertion of jurisdiction to review the acquisition under Article 22 of the EU Merger Regulation, as the acquisition does not meet the jurisdictional criteria under the EU Merger Regulation or under the national merger control laws of any Member State of the European Union. On December 16, 2021, the EU General Court held a hearing regarding the European Commission’s assertion of jurisdiction. On July 13, 2022, the EU General Court reached a decision in favor of the European Commission, holding that the European Commission has jurisdiction under the EU Merger Regulation to review the acquisition. 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 October 29, 2021, the European Commission adopted an order imposing interim measures (the Initial Interim Measures Order). As the Initial Interim Measures Order was set to expire on November 3, 2022, the European Commission adopted a new order imposing interim measures (the New Interim Measures Order) on October 28, 2022. On December 1, 2021, we filed an action with the EU General Court asking for annulment of the Initial Interim Measures Order. The hearing of that application has been stayed pending our appeal of the judgment of the EU General Court regarding the European Commission’s assertion of jurisdiction. 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. 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.
On September 6, 2022, the European Commission announced that it had completed its Phase II review of the acquisition of GRAIL 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. Public statements made byOn 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 in connection with the Prohibition Decision indicate thatadopted a subsequent decision is likely to be adopted by the European Commission that will orderrequiring us to (among other things) divest GRAIL, and replacing the interim measures set forth in the New Interim Measures Order with substantially equivalent transitional measures (the EC Divestment Decision). Neither the Prohibition Decision nor such public statements indicate when any such EC Divestment Decision may be adopted. We intend to appeal the Prohibition Decision toEC Divestment Decision.
On July 12, 2023, the European Commission adopted a final decision finding that we breached the EU General CourtMerger Regulation by, in its view, acquiring the applicable deadline. We also intendpossibility to appeal any EC Divestment Decision (ifexert decisive influence over GRAIL and when adopted by the European Commission) and, if necessary, to seek interim relief suspending the divestment of GRAIL until the final determination of these appeals.
Additionally, as a result of our decision to proceed with the completion of the acquisition of GRAILexerting such influence during the pendency of the European Commission’s review the(the Article 14(2)(b) Decision). The European Commission will likely seek to imposetherefore imposed a fine on us pursuant to Article 14(2)(b) of the EU Merger Regulation of up to 10%approximately €432 million, representing the maximum fine of our consolidated annual revenues. On July 19, 2022, the European Commission issued a Statement of Objections alleging that we breached the EU Merger Regulation by completing our acquisition of GRAIL. As a result, we have accrued $453 million, included in accrued liabilities, as of Q3 2022, which represents 10% of our consolidated annual revenues for fiscal year 20212022. We provided guarantees in accordance with ASC 450, Contingencies.
BGI Genomics Co. Ltd.October 2023 to satisfy the obligation in lieu of cash payment while we appeal the European Commission’s jurisdictional decision and its Affiliates
On June 27, 2019, we filed suit against BGI Genomics Co. Ltd (BGI) in the United States District Court for the Northern Districtfine decision. The fine is accruing interest at a rate of California, alleging that certain BGI sequencing products infringe our U.S. Patent No. 7,566,537 (‘537 patent) and U.S. Patent No. 9,410,200 (‘200 patent). BGI denied our claims and counterclaimed that our technology infringes U.S. Patent No. 9,944,984 (‘984 patent). We deny their allegations. On February 27, 2020, we filed a second patent infringement suit against BGI in the United States District Court for the Northern District of California alleging that BGI sequencing products infringed U.S. Patent 7,771,973 (‘973 patent), U.S. Patent 7,541,444 (‘444 patent), and U.S. Patent 10,480,025 (‘025 patent). On June 15, 2020, the Court granted our motions requesting preliminary injunctions against BGI, finding that our patents were likely valid and infringed by5.5% per annum,

As of October 1, 2023, we accrued $458 million, including related foreign currency gains (which were recorded in other expense, net), included in accrued liabilities. We appealed the saleArticle 14(2)(b) Decision on September 26, 2023.
SEC Inquiry Letter
In July 2023, we were informed that the staff of infringing BGI sequencersthe SEC was conducting an investigation relating to Illumina and sequencing reagentswas requesting documents and communications primarily related to Illumina’s acquisition of GRAIL and certain statements and disclosures concerning GRAIL, its products and its acquisition, and related to the conduct and compensation of certain members of Illumina and GRAIL management, among other things. Illumina is cooperating with the SEC in this investigation.
Derivative and Class Action Complaint
On October 17, 2023, a stockholder derivative and class action complaint captioned Icahn Partners LP, et al. v. deSouza, et al., purportedly brought on behalf of Illumina and public holders of Illumina’s common stock, was filed in the U.S. On December 9, 2020, BGI filedDelaware Court of Chancery against certain current and former directors (including our former Chief Executive Officer). We are named as a motionnominal defendant in the complaint. The lawsuit alleges the named directors breached their fiduciary duties by knowingly causing Illumina to amend its answerunlawfully close the GRAIL acquisition, concealing material facts related to our second suitthe GRAIL acquisition and making inadequate disclosures. Prior to include allegations that the ‘444 and ‘973 patents are unenforceable underfiling of the doctrine of inequitable conduct; we deny BGI’s allegations. We deny that we owe any damages or ongoing royalty. On August 27, 2021, and September 9, 2021,complaint, the Court issued its decisions on the summary judgment motions: (i) the Court granted our motion for summary judgment that we dopurported stockholders did not infringe BGI’s ‘984 patent; (ii) the Court granted our motion for summary judgmentmake a demand that our ‘444Board of Directors pursue the claims asserted therein. The complaint seeks damages, costs and ‘973 patents are not unenforceable; (iii)expenses, including attorney fees, the Court granted our motion for summary judgment that BGI’s standard MPS products infringe allcertification and consolidation of our patents-in-suit: (iv)a putative class, the Court granted our motion for summary judgment that BGI’s “Cool MPS” sequencing products infringeissuance of amended disclosures, the ‘973removal of conflicted directors and ‘444 patents,declaratory and granted BGI’s motion for summary judgment that BGI’s “Cool MPS” sequencing products do not infringeother equitable relief. Since the ‘025 patent; and (v)lawsuit is brought in part on behalf of Illumina as a nominal defendant, the Court denied BGI’s motion for summary judgment that our ‘973 patent is invalid for lack of written description and enablement. Trial began on November 12, 2021, and the jury rendered a verdict on November 30, 2021. The jury found that the ‘537, ‘200, ‘973 patents and claims 9, 27, 31, 33, 34, 42, 47 of the ‘025 patent are valid andalleged damages were willfully infringedallegedly suffered by BGI. The jury also ruled that the claim 4 of the ‘444 patent and claim 1 of the ‘025 patent were invalid as obvious. The jury awarded the Company $8 million in damages. On March 27, 2022, the Court issued a decision on post-trial motions. The Court denied BGI’s motions. The Court (i) upheld the jury’s award of $8 million and granted pre-judgment interest, (ii) upheld the jury’s finding that BGI’s infringement was willful, (iii) granted the Company’s request for a permanent injunction until the relevant patents expire; (iv) granted the Company’s request that claim 1 of the ‘025 patent is not invalid, but denied the request with respect to claim 4 of the ‘444 patent; and (v) denied the Company’s request for enhanced damages. On April 27, 2022, BGI appealed the judgment to the United States Court of Appeals for the Federal Circuit. The Company cross-appealed, including with respect to the denial of the Company’s request for enhanced damages.
On January 11, 2021, Complete Genomics, Inc. (CGI), BGI Americas Corp., and MGI Americas, Inc. filed a complaint in the United States District Court for the Northern District of California alleging the Company and its subsidiary Illumina Cambridge Ltd. violated federal antitrust and state unfair competition laws. CGI and these affiliates alleged that the Company fraudulently withheld a prior art reference that was material to patentability for the ‘444 and ‘973 patents. They also alleged that our infringement claims of the ‘025 against BGI’s “Cool MPS” chemistry were objectively baseless. The Company deniesus. We deny the allegations in the complaint. On March 30, 2021, the Court stayed the antitrust case pending resolution of the underlying patent infringement suit taking place in the same court.
On May 28, 2019, CGI filed suit against us in the United States District Court for the District of Delaware alleging that our two-channel sequencing systems, including the NovaSeq, NextSeq,complaint and MiniSeq systems, infringe certain claims of U.S. Patent No. 9,222,132. We denied CGI’s allegations and counterclaimed for infringement by CGI, BGI Americas Corp., and MGI Americas, Inc. of U.S. Patent No. 9,303,290, U.S. Patent No. 9,217,178, and U.S. Patent No. 9,970,055. On August 15, 2019, CGI filed a motion to dismiss our counterclaims. On August 29, 2019, we filed our Opposition to the Motion to Dismiss. The Court denied and granted the motion in part, denying the motion as to our claims for inducing infringement and granting it for contributory infringement. The Court gave us leave to file an amended complaint to attempt to cure the alleged deficiencies as to contributory infringement. On July 1, 2020, CGI amended its complaint to add claims of infringement of U.S. Patent No. 10,662,473 by our two-channel sequencing systems. We deny these allegations. CGI requested approximately $334 million in alleged past damages and an average ongoing royalty of at least 5.5% on sales of the accused two-channel sequencing instruments and chemistry in the U.S. until the patents-in-suit expire on January 28, 2029. We denied that we owed any damages or ongoing royalty. On October 22, 2021, pursuant to the Court’s local rules, the Company sought leave to file a motion for summary judgment of non-infringement of the CGI patents-in-suit. CGI sought leave to file a motion for summary judgment against the Company’s invalidity defense based on prior invention. On January 14, 2022, the Court denied the Company and CGI’s motions for leave to file for summary judgment. Trial began on April 25, 2022.
On May 6, 2022, the jury in the U.S. District Court for the District of Delaware rendered a verdict that we willfully infringed U.S. Patent Nos. 9,222,132 and 10,662,473 owned by CGI, and awarded approximately $334 million to CGI in past damages. The jury also invalidated three patents owned by us, namely, U.S. Patent Nos. 9,217,178; 9,303,290; and 9,970,055. On July 14, 2022, we entered into a Settlement and License Agreement with BGI and CGI (the “Agreement”). The Agreement resolves all claims in Complete Genomics, Inc. v. Illumina, Inc., Case No. C.A. No. 19-970-MN (D. Del.). The Agreement also resolves all claims in Illumina, Inc. and Illumina Cambridge Ltd. v. BGI Genomics Co., Ltd., BGI Americas Corp., MGI Tech Co., Ltd., MGI Americas Inc., and Complete Genomics, Inc., Case No. 3:19-cv-03770-WHO (N.D. Cal.) and Illumina, Inc. and Illumina Cambridge Ltd. v. BGI Genomics Co., Ltd., BGI Americas Corp., MGI Tech Co., Ltd., MGI Americas Inc., and Complete Genomics, Inc., Case No. 3:20-

cv-01465-WHO (N.D. Cal.), as well as related Appeal Nos. 2022-1733, 2022-1735 and 2022-1742, 2022-1743 pending in the United States Court of Appeals for the Federal Circuit, with the exception that the permanent injunction entered on April 11, 2022 against BGI remains in effect with a revised expiration date of January 1, 2023, with respect to BGI’s StandardMPS chemistry. The Agreement further resolves all antitrust claims against us in Complete Genomics, Inc., BGI Americas Corp. and MGI Americas, Inc. v. Illumina, Inc. and Illumina Cambridge Ltd., Case No. 21-cv-00217 (N.D. Cal.) and that complaint was dismissed with prejudice. Pursuant to the terms of the Agreement, the Company agreed to pay Complete Genomics a one-time payment of $325 million, with the parties agreeing that the judgment against BGI and the judgment against the Company in the above-referenced litigations are satisfied in total. In addition, the Company received from BGI a fully paid-up license to U.S. Patent Nos. 8,617,811, 9,222,132, 9,523,125, 10,662,473, 11,098,356 and 11,214,832, U.S. Patent Application Nos. 61/024,396, 61/024,110, 16/882,461, 17/407,935 and 17/523,706, and U.S. patents and patent applications related to each of the foregoing U.S. patents and patent applications until their expiration (“the 2-channel technology patents”). Our license allows the Company to use the 2-channel technology in all its current and future platforms with no additional royalties owed. BGI received from us a fully paid-up license to U.S. Patent Nos. 9,217,178, 9,303,290 and 9,970,055 (“the image mix patents”) and U.S. patents and applications related to each of the foregoing U.S. patents until their expiration. The parties agreed to a litigation standstill for patent and antitrust actions in the United States and its territories until October 1, 2025, as set forth in the Agreement. The standstill does not apply to the parties’ patents or patent applications related to non-invasive prenatal testing, nor to any intellectual property of Grail, Inc., related to multi-cancer early detection. None of the parties make any admission of liability in entering into the Agreement.
We allocated the $325 million payment on a relative fair value basis, resulting in $180 million capitalized as an intangible asset for the value of the license, which is amortized over a period of 6.5 years on a straight-line basis, $150 million allocated to the release of past damages claimed, and a $5 million gain for damages awarded to us. The fair value of the license was estimated using a discounted cash flow model, which included assumptions for projected revenues covered by the license, an estimated royalty rate and a discount rate. The fair value of the past damages claimed was estimated based on applicable historical revenues and an estimated royalty rate. These inputs represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value. As of Q2 2022, we had accrued $156 million for the release of past damages claimed. The settlement of the litigation resulted in a gain of $6 million, calculated as the difference between the accrual released and the amount of payment allocated to the release of past damages claimed.
RavGen
On December 3, 2020, RavGen filed a patent infringement suit against the Company claiming the Company’s use of Streck, Inc. sample collection tubes in its Verifi, Verifi Plus, and VeriSeq NIPT and liquid biopsy oncology products infringe U.S. Patent Nos. 7,332,277 and 7,727,720 (RavGen, Inc. v. Illumina, Inc., United States District Court for the District of Delaware, Case No. 1:20-cv-01644-UNA). The patents-in-suit are directed to the use of a sample-stabilizing agent that inhibits the lysis of cells. RavGen is seeking, among other things, an unspecified amount of damages, an injunction, and reasonable attorneys’ fees. The patents expire March 13, 2023.
On January 27, 2021, the Company filed its Answer and Counterclaims denying all allegations in the Complaint and seeking declaratory judgment of non-infringement and invalidity.
On July 20, 2021, the Company filed Petitions for Inter Partes Review (IPR) of the ‘277 and ‘720 patents-in-suit with the US Patent Trial and Appeal Board seeking to invalidate certain claims of the patents (PTAB) (IPR2021-01272 and IPR2021-01271). On January 26, 2022, the PTAB instituted the IPRs. The PTAB’s final written decisions in the IPRs are due by January 26, 2023.
On March 1, 2022, the District Court granted the Company’s motion to stay the litigation pending resolution of the IPRs. The Company intendsintend to vigorously defend against Ravgen’s claims.
the litigation. In parallel, on December 15, 2020,light of the Company requested Streck, Inc. to indemnify the Company in the RavGen litigation. On January 6, 2021, Streck responded, denying any obligation to indemnify the Company. Streck also requestedfact that the Company stay its indeminification request pending resolutionlawsuit is in an early stage, we cannot predict the ultimate outcome of the underlying patent infringement suit. The Company and Streck executed a tolling agreement effective April 2, 2021, staying the Company’s indemnification claim pending resolution of the underlying patent suit.

We currently cannot estimate the possible loss or range of loss, if any, that may result from RavGen’s claims against us.
8. INCOME TAXES
Our effective tax rate may vary from the U.S. federal statutory tax rate due to the change in the mix of earnings in tax jurisdictions with different statutory rates, benefits related to tax credits, and the tax impact of non-deductible expenses and other permanent differences between income before income taxes and taxable income.
Our effective tax rates for Q3 20222023 and YTD 2022 2023were (4.0)%3.6% and (2.3)(3.8)%, respectively, compared to 24.7%(4.0)% and 18.6%(2.3)% in Q3 20212022 and YTD 2021,2022, respectively. The variance from the U.S. federal statutory tax rate of 21% in Q3 20222023 and YTD 20222023 was primarily because ofattributable to the $822$149 million income tax expense impact from the impairment of goodwill, which is nondeductible for tax purposes, the $64$20 million and $91$84 million income tax impactsexpense impact of research and development expense capitalization for tax purposes, respectively, and the $30$38 million and $60$63 million income tax impactsexpense impact of GRAIL pre-acquisition net operating losses on global intangible low-taxed income (GILTI) and the utilization of U.S. foreign tax credits, respectively. This was partially offset by the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as in Singapore andSingapore.

Historically, we calculated the United Kingdom.
In YTD 2022, the variance from the U.S. federal statutoryprovision/(benefit) for income taxes for interim periods utilizing an estimated annual effective tax rate of 21% was also impacted by the $95 million tax impact from the potential European Commission fine relatedapplied to the GRAIL acquisition, which is nondeductibleincome/(loss) for the reporting period, except in Q2 2023 when a year-to-date effective tax purposes.rate method was utilized. We determined the estimated annual effective tax rate method would provide a more reliable estimate of the provision for income taxes for Q3 2023 and YTD 2023, since minor changes in the estimated income/(loss) before income taxes would not result in significant changes in the estimated annual effective tax rate.
As of October 2, 20221, 2023 and January 2, 2022,1, 2023, prepaid income taxes, included within prepaid expenses and other current assets on the condensed consolidated balance sheets, were $54$78 million and $101$116 million, respectively. The decrease primarily relates to the tax expense recorded in Q3 2022.

9. SEGMENT INFORMATION
We have two reportable segments, Core Illumina and GRAIL. We report segment information based on the management approach, which designates the internal reporting used by the Chief Operating Decision Maker (CODM) for making decisions and assessing performance as the source of our reportable segments. The CODM allocates resources and assesses the performance of each operating segment using information about its revenue and income (loss) from operations. Our CODM does not evaluate our operating segments using discrete asset information. We do not allocate expenses between segments. Core Illumina sells products and provides services to GRAIL, and vice versa, in accordance with contractual agreements between the entities.
Core Illumina:
Core Illumina’s products and services serve customers in the research, clinical and applied markets, and enable the adoption of a variety of genomic solutions. Core Illumina includes all of our operations, excluding the results of GRAIL.
GRAIL:
GRAIL is a healthcare company focused on early detection of multiple cancers. We acquired GRAIL on August 18, 2021. We have included the financial results of GRAIL in our condensed consolidated financial statements from the date of acquisition.

On August 18, 2021, we acquired GRAIL, a healthcare company focused on early detection of multiple cancers. GRAIL’s Galleri blood test detects various types of cancers before they are symptomatic. We believe our acquisition of GRAIL will accelerate the adoption of next-generation sequencing based early multi-cancer detection tests, enhance our position in Clinical Genomics, and increase our directly accessible total addressable market. The acquisition is subject to ongoing legal proceedings and, currently, GRAIL is currently beingmust be held and operated as a separate company, with oversight providedseparately and independently from Illumina pursuant to the transitional measures ordered by an appointed, independent monitoring trustee.the European Commission in the EC Divestment Decision, following the prohibition of our acquisition of GRAIL on September 6, 2022. See note “7. Legal Proceedings” for further details.
With respect to GRAIL, we have retained advisors and are preparing for sale and capital markets transaction options in accordance with the European Commission’s divestiture order. In parallel, ongoing appeals preserve flexibility for any divestiture of GRAIL and future transactions.
We have includedtwo reportable segments, Core Illumina and GRAIL. Core Illumina relates to our core operations, excluding the financial results of GRAIL in our condensed consolidated financial statements from the date of acquisition. GRAIL is a separate reportable segment.GRAIL. See note “9. Segment Information” for additional details.
Our financial results have been, and will continue to be, impacted by several significant trends, which are described below. While these trends are important to understanding and evaluating our financial results, this discussion should be read in conjunction with our condensed consolidated financial statements and the notes thereto within the Condensed Consolidated Financial Statements section of this report, and the other transactions, events, and trends discussed in “Risk Factors” within the Other Key Information section of this report.
Financial Overview
Since 2020, the COVID-19 pandemic and international efforts to control its spread have significantly curtailed the movement of people, goods, and services worldwide, including in the regions where we sell our products and services and conduct our business operations. In addition, armed conflict between Russia and Ukraine, which began in 2022, and the sanctions imposed by the U.S. and other countries, may impacthas impacted our ability to ship products into affected regions.regions and to designated customers. Furthermore, macroeconomic factors such as inflation, exchange rates and concerns about an economic downturn, and competitive challenges in our China region, have impacted both Illumina directly and our customers’ behavior, and we expect these factors to continue to impact our business through 2022.behavior. For example, some customers experienced supply chain pressures that delayed their lab expansions and others are managing inventory and capital more conservatively. We expect these factors to continue to impact our sales and results of operations for the remainder of 2023, the size and duration of which is significantly uncertain.
Financial highlights for YTD 20222023 included the following:
Revenue increased 5%decreased 3% in YTD 2023 to $3,382 million compared to $3,501 million in YTD 2022 to $3,501 million compared to $3,327 million in YTD 2021 primarily due to growthdecreases in sequencing consumables revenue and sequencing instruments as well asrevenue, partially offset by an increase in service and other revenue. We expect our revenue to be flatdecrease 2% to 1% higher3% in 20222023 compared to 2021.2022.
Gross profit as a percentage of revenue (gross margin) was 61.2% in YTD 2023 compared to 65.7% in YTD 2022 compared to 70.2% in YTD 2021.2022. The decrease in gross margin was driven primarily by less fixed cost leverage on lower manufacturing volumes, lower instrument margins due to the gross loss incurred by GRAILNovaSeq X launch in YTD 2022.Q1 2023, and unfavorable product mix. Our gross margin depends on many factors, including: market conditions that may impact our pricing; sales mix changes among consumables, instruments, services, and development and licensing revenue; product mix changes between established products and new products; excess and obsolete inventories; royalties; our cost structure for manufacturing operations relative to volume; freight costs; and product support obligations.
Loss from operations as a percentage of revenue was (115.7)%$905 million in YTD 20222023 compared to (5.0)%$4,052 million in YTD 2021.2022. The decrease was primarily due to goodwill impairment related to GRAIL, a legal contingency recorded related to the potential European Commission fine, a loss related to our settlement with BGI and a decrease in operating expense of $3,377 million, which included significant decreases in goodwill and intangible impairment of $3,093 million and legal contingency and settlement of $584 million, partially offset by a $230 million decrease in gross margin.profit.

Our effective tax rate was (3.8)% in YTD 2023 compared to (2.3)% in YTD 2022 compared to 18.6% in YTD 2021.2022. The variance from the U.S. federal statutory tax rate of 21% was primarily because of the income tax impactsexpense impact of the impairment of goodwill, and the potential European Commission fine related to the GRAIL acquisition which areis nondeductible for tax purposes, the income tax expense impact of research and development expense capitalization for tax purposes, and the income tax expense impact of GRAIL pre-acquisition net operating losses on GILTI and the utilization of U.S. foreign tax credits. This was partially offset by the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as in Singapore and the United Kingdom.Singapore.
We ended Q3 20222023 with cash, cash equivalents, and short-term investments totaling $1.0 billion as of October 2, 2022,$933 million, of which approximately $537$499 million was held by our foreign subsidiaries.

The decreasesdecrease in Core Illumina gross margin in Q3 20222023 and YTD 2022 were2023 was driven primarily by less fixed cost leverage on lower manufacturing volumes, lower instrument margins due to the NovaSeq X launch, which is typical with a new platform introduction until we scale manufacturing and higher freightgain operating efficiencies, and unfavorable product mix, as well as increased field services and installation costs, partially offset by favorable product mix. The decrease in YTD 2022 was also driven by increased revenue from a patent litigation settlement in Q2 2021.lower freight costs.

Interest expense in Q3 2022 and YTD 2022 consisted primarily of accrued interest on our Term Notes. The decreases in Q3 2022 and YTD 2022 were primarily due to the accretion of the original debt discount on our convertible senior notes, prior to the adoption of ASU 2020-06. The decrease in YTD 2022 was also due to the recognition of interest expense in YTD 2021 associated with the amortization of debt issuance costs related to the termination of our Bridge Facility in Q1 2021. The decreases in other (expense) income, net in Q3 2022 and YTD 2022 were primarily due to the gain of $900 million from our previously held investment in GRAIL, which was recorded in Q3 2021 as part of the acquisition, as well as higher unrealized losses on our marketable equity securities and Helix contingent value right in Q3 2022 and YTD 2022.

The variance from the U.S. federal statutory tax rate of 21% for Q3 2023 and YTD 2023 was primarily because of the $822$149 million income tax expense impact from the impairment of goodwill, which is nondeductible for tax purposes, the $30$20 million and $84 million income tax expense impact of capitalizing research and development expenses for tax purposes, respectively, and the $38 million and $63 million income tax expense impact of GRAIL pre-acquisition net operating losses on GILTI and the utilization of U.S. foreign tax credits, respectively. The income tax expense in Q3 2023 and YTD 2023 were also favorably impacted by the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as in Singapore.
The income tax benefits in Q3 2022 and YTD 2022 had an effective tax rate that was lower than the U.S. federal statutory tax rate of 21% primarily because of the $822 million income tax expense impact from the impairment of goodwill, which is nondeductible for tax purposes, the $64 million and $91 million income tax expense impact of capitalizing research and development expenses, respectively, and the $30 million and $60 million income tax expense impact of GRAIL pre-acquisition net operating losses on GILTI and the utilization of the U.S. foreign tax credits, respectively. The YTD 2022 income tax benefit was also impacted by the $95 million income tax expense impact from the European Commission fine related to the GRAIL acquisition, which was accrued in Q2 2022 and is nondeductible for tax purposes beginning in 2022, in accordance with the 2017 Tax Cuts and Jobs Act. If the capitalization requirement is not repealed or modified, potentially retroactively to the beginning of 2022, our provision for income taxes will continue to be negatively impacted and our future cashpurposes. Our effective tax payments will increase by approximately $163 million due to the impact of capitalizing research and development expenses in 2022.

Historically, we calculated the variance from the U.S. federal statutory tax rate of 21% was primarily attributable to discrete tax benefits related to GRAIL Continuation Payments and the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as in Singapore and the United Kingdom.
Ourprovision/(benefit) for income taxes for interim periods utilizing an estimated annual effective tax rate was (2.3)%applied to the income/(loss) for the reporting period, except in YTD 2022 compared to 18.6% in YTD 2021. The variance from the U.S. federal statutoryQ2 2023 when a year-to-date effective tax rate of 21%method was primarily becauseutilized.We determined the estimated annual effective tax rate method would provide a more reliable estimate of the $822 millionprovision for income taxes for Q3 2023 and YTD 2023, since minor changes in the estimated income/(loss) before income taxes would not result in significant changes in the estimated annual effective tax impact from the impairment of goodwill and the $95 million tax impact from the potential European Commission fine related to the GRAIL acquisition, both of which are nondeductible for tax purposes, the $91 million tax impact of capitalizing research and development expenses for tax purposes beginning in 2022, in accordance with the 2017 Tax Cuts and Jobs Act, and the $60 million tax impact of GRAIL pre-acquisition net operating losses on GILTI and the utilization of the U.S. foreign tax credits. The tax expense in YTD 2022 was also favorably impacted by the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as in Singapore and the United Kingdom.
In YTD 2021, the variance from the U.S. federal statutory tax rate of 21% was primarily attributable to discrete tax benefits related to GRAIL Continuation Payments and the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as in Singapore and the United Kingdom. This was partially offset by tax expense on certain foreign subsidiary earnings that are no longer indefinitely reinvested.rate.
Our future effective tax rate may vary from the U.S. federal statutory tax rate due to the mix of earnings in tax jurisdictions with different statutory tax rates and the other factors discussed in the risk factor “We are subject to risks related to taxation in multiple jurisdictions” described in “Risk Factors” within the Business & Market Information section of our Annual Report on Form 10-K for the fiscal year ended January 2, 2022.1, 2023.
LIQUIDITY AND CAPITAL RESOURCES
AtAs of October 2, 2022,1, 2023, we had approximately $1.0 billion$927 million in cash and cash equivalents, of which approximately $537$499 million was held by our foreign subsidiaries. Cash and cash equivalents decreased by $232$1,084 million from January 2, 2022,1, 2023 due primarily to the repayment of our 2023 Term Notes in Q1 2023 of $500 million, the repayment of our 2023 Convertible Notes in Q3 2023 of $750 million, and other factors described in the “Cash Flow Summary” below. Our primary source of liquidity, other than our holdings of cash, cash equivalents, and investments, has been cash flows from operations and, from time to time, issuances of debt. Our ability to generate cash from operations provides us with the financial flexibility we need to meet operating, investing, and financing needs.

Historically, we have liquidated our short-term investments and/or issued debt convertible debt, and equity securities to finance our business needs as a supplement to cash provided by operating activities. As of October 2, 2022,1, 2023, we had $41$6 million in short-term investments comprised of marketable equity securities.
On July 12, 2023, as a result of our decision to proceed with the completion of our acquisition of GRAIL during the pendency of the European Commission’s review, the European Commission imposed a €432 million fine on us, representing the maximum fine of 10% of our consolidated annual revenues for fiscal year 2022. As of October 2,1, 2023, we accrued $458 million, including related foreign currency gains, included in accrued liabilities. 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. The fine is accruing interest at a rate of 5.5% per annum, beginning in October 2023, while it is outstanding. Refer to note “7. Legal Proceedings” for additional details.
In March 2021, we issued term notes due 2023 with an aggregate principal amount of $500 million and term notes due 2031 with an aggregate principal amount of $500 million. The 2023 Term Notes matured and were repaid in cash on March 23, 2023. The 2031 Term Notes, which mature on March 23, 2031, accrue interest at a rate of 2.550% per annum, payable semi-annually in March and September of each year. We may redeem for cash all or any portion of the 2031 Term Notes, at our option, at any time prior to maturity.
Our convertible senior notes, with an aggregate principal amount of $750 million, matured on August 15, 2023, at which time the principal was repaid in cash. We did not issue any shares of common stock.
In December 2022, we issued term notes due 2025 with an aggregate principal amount of $500 million and term notes due 2027 with an aggregate principal amount of $500 million. The 2025 Term Notes, which mature on December 12, 2025, and the 2027 Term Notes, which mature on December 13, 2027, accrue interest at a rate of 5.800% and 5.750% per annum, respectively, payable semi-annually in June and December of each year. We may redeem for cash all or any portion of the 2025 or 2027 Term Notes, at our option, at any time prior to maturity.
On January 4, 2023, we obtained a new Credit Facility, which provides us with a $750 million senior unsecured five year revolving credit facility, including a $40 million sublimit for swingline borrowings and a $50 million sublimit for letters of credit. The Credit Facility matures, and all amounts outstanding thereunder become due and payable in full, on January 4, 2028, subject to two one-year extensions at our option and the consent of the extending lenders and certain other conditions. As of October 1, 2023, there were no borrowings outstanding under the Credit Facility; however, we may draw upon the facility in the future to manage cash flow or for other corporate purposes, including in connection with the payment of the €432 million European Commission fine. 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 October 1, 2023, the fair value of our contingent consideration liability related to our acquisition of GRAIL was $387 million.$330 million, of which $329 million was included in other long-term liabilities. The contingent value rights issued as part of the acquisition entitle the holders to receive future cash payments on a quarterly basis (Covered Revenue Payments) representing a pro rata portion of certain GRAIL-related revenues (Covered Revenues) each year for a 12-year period. This will reflect a 2.5% payment right to the first $1 billion of revenue each year for 12 years. Revenue above $1 billion each year will be subject to a 9% contingent payment right during this same period. We expect Covered Revenues for Q4 2021, Q1 2022,Q3 2023 to be approximately $21 million and Q2 2022 were $32 million in aggregate, driven primarily by sales of GRAIL’s Galleri test. Corresponding Covered Revenue Payments in YTD 2022 were approximately $297,000; however, pursuant to the Contingent Value Rights Agreement, a portion of the Covered Revenue Payments were applied to reimburse us for certain expenses. We expectrelated Covered Revenue Payments to total approximately $99,000$194,000 in Q4 2022 due2023. In YTD 2023, we paid $609,000 in aggregate Covered Revenue Payments related to Covered Revenues for Q3Q4 2022, Q1 2023, and Q2 2023 of approximately $10 million.$65 million in aggregate.
We continued to grant GRAIL employees cash incentive equity awards to GRAIL employees that generally have terms of four years and vest in YTD 2022.equal annual installments. As of October 2, 2022,1, 2023, the aggregate cash value of awards outstanding and unvested was $226$308 million, and we accrued an estimated liability of $24$42 million, included in accrued liabilities. In addition, we have an outstanding performance-based award for which vesting is based on GRAIL’s future revenues. The award has an aggregate potential value of up to $78 million, which is expected to be settled in cash, and expires, to the extent unvested, in August 2030. As of October 2, 2022,1, 2023, it was not probable that the performance conditions associated with the award will be achieved.
As a result of our decision to proceed with the completion of our acquisition of GRAIL during the pendency of the European Commission’s review, the European Commission will likely seek to impose a fine on us. In YTD 2022, we accrued $453 million, included in accrued liabilities, representing 10% of our consolidated annual revenues for fiscal year 2021, as further disclosed in note “7. Legal Proceedings.”
On March 23, 2021, we issued term notes due 2023 with an aggregate principal amount of $500 million and term notes due 2031 with an aggregate principal amount of $500 million. The 2023 Term Notes and the 2031 Term Notes accrue interest at a rate of 0.550% and 2.550% per annum, respectively, payable semi-annually on March 23 and September 23 of each year. The 2023 Term Notes, which are classified as short-term, mature on March 23, 2023 and the 2031 Term Notes mature on March 23, 2031. We may redeem for cash all or any portion of the Term Notes, at our option, at any time prior to maturity. Our convertible senior notes, with an aggregate principal amount of $750 million, which are classified as short-term and due on August 15, 2023, were not convertible as of October 2, 2022. The holders may convert their notes on or after May 15, 2023 until August 11, 2023.
On March 8, 2021, we obtained a Credit Facility, which provides us with a $750 million senior unsecured five-year revolving credit facility, including a $40 million sublimit for swingline borrowings and a $50 million sublimit for letters of credit. The Credit Facility matures, and all amounts outstanding thereunder become due and payable in full, on March 8, 2026, subject to two one-year extensions at our option and the consent of the extending lenders and certain other conditions. As of October 2, 2022, there were no borrowings outstanding under the Credit Facility.
We had $11$5 million and up to $101$74 million, respectively, remaining in our capital commitments to two venture capital investment funds as of October 2, 20221, 2023 that are callable through April 2026 and July 2029, respectively.
Authorizations to repurchase $15 million of our common stock remained available as of October 2, 20221, 2023 under the $750 million share repurchase program authorized by our Board of Directors on February 5, 2020. The repurchases may be completed under a 10b5-1 plan or at management’s discretion. We do not intend to make any share repurchases during fiscal year 2022.2023.
We anticipate that our current cash, cash equivalents, and short-term investments, together with cash provided by operating activities and available borrowing capacity under the Credit Facility, are sufficient to fund our near-term capital and operating needs for at least the next 12 months. Operating needs include the planned costs to operate our business, including amounts required to fund working capital and capital expenditures. Our primary short-term needs for capital, which are subject to change, include:
support of commercialization efforts related to our current and future products;

acquisitions of equipment and other fixed assets for use in our current and future manufacturing and research and development facilities;
the continued advancement of research and development efforts;
the payment of the European Commission fine related to our acquisition of GRAIL;
the requirement to ensure that GRAIL has access to sufficient funds, at the time of a divestment, to cover at least 2.5 years of operations according to its latest long-range plan per the EC Divestment Decision;
potential strategic acquisitions and investments;
repayment of debt obligations; and
the expansion needs of our facilities, including costs of leasing and building out additional facilities.
We expect that our revenue and the resulting operating income, as well as the status of each of our new product development programs, will significantly impact our cash management decisions.
Our future capital requirements and the adequacy of our available funds will depend on many factors, including:
our ability to successfully commercialize and further develop our technologies and create innovative products in our markets;
scientific progress in our research and development programs and the magnitude of those programs;

competing technological and market developments; and
the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
In preparing our condensed consolidated financial statements, we make estimates, assumptions and judgments that can have a significant impact on our net revenue, operating income (loss) and net income (loss), as well as on the value of certain assets and liabilities on our balance sheet. We believe that the estimates, assumptions and judgments involved in the accounting policies described in “Critical Accounting Policies and Estimates” within the Management’s Discussion & Analysis section of our Annual Report on Form 10-K for the fiscal year ended January 2, 20221, 2023 have the greatest potential impact on our financial statements, so we consider them to be our critical accounting policies and estimates. Though the impact of the COVID-19 pandemic, to our businessthe armed conflict between Russia and operating results presentsUkraine, and macroeconomic factors such as inflation, exchange rates and concerns about an economic downturn present additional uncertainty, we continue to use the best information available to inform our critical accounting estimates. There were no material changes to our critical accounting policies and estimates during YTD 2022.

RISK FACTORS
Our business is subject to various risks, including those described in “Risk Factors” within the Business & Market Information Sectionsection of our Annual Report on Form 10-K for the fiscal year ended January 2, 2022, and1, 2023, the “Other Key Information” section of our Quarterly Report on Form 10-Q for the period ended April 3, 2022,2, 2023 and on Form 10-Q for the period ended July 2, 2023, which we strongly encourage you to review. In addition to the risk factors disclosed in our Form 10-KForm10-K,Form 10-Q for Q1 2023 and Form 10-Q for Q2 2023, the issues raised in the following risk factorsfactor could adversely affect our operating results and stock price:
Our acquisition (the Acquisition) of GRAIL remains subject to ongoing legal and regulatory proceedings in the United States and in the European Union. Adverse decisions by the EU General Court,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, could resulthave 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.
As previously disclosed, on March 30, 2021, the U.S. Federal Trade Commission (the FTC)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. We filed an answer to the FTC’s complaint in the administrative court on April 13, 2021, and the administrative trial commenced on August 24, 2021. 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. In the decision, the ALJ found that the FTC’s complaint counsel had failed to prove its prima facie case that Illumina’s acquisition of GRAIL would result in harm to competition in a putative market for multi-cancer early detection (MCED) tests. The FTC’s complaint counsel appealed the ALJ’s decision to the full FTC on September 2, 2022,2022. On March 31, 2023, the FTC issued an opinion and on October 4, 2022,order (the FTC Order) requiring Illumina to divest GRAIL, reversing the FTC’s complaint counselALJ’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. Illumina submitted its opening appeal brief. on June 5, 2023. The appeal was fully briefed as of August 16, 2023 and oral argument occurred on September 12, 2023. We intend to continue to vigorously defend against the FTC action.
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. The European Commission had previously notified us asserting that as a result of the Referral, pursuant to Article 22(4) of the EU Merger Regulation, we were prohibited from implementing the Acquisition (i) until the European Commission clears the Acquisition under the EU Merger Regulation or (ii) until the European Commission refuses the Referral, and therefore the European Commission’s acceptance of the Referral continued the purported standstill on the completion of the Acquisition until such time as the European Commission completes its review and approves the Acquisition. On April 29, 2021, we filed an action in the General Court of the European Union (the EU General Court) asking for annulment of the European Commission’s decision asserting jurisdiction to review the Acquisition under Article 22 of the EU Merger Regulation, as the Acquisition does not meet the jurisdictional criteria under the EU Merger Regulation or under the national merger control laws of any Member State of the European Union. On December 16, 2021, the EU General Court held a hearing regarding the European Commission’s assertion of jurisdiction. 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.
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 certain operational modifications and also expressly prohibits Illumina from 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. As the Initial Interim Measures Order was set to expire on November 3, 2022, the European Commission adopted a new order imposing interim measures (the New Interim Measures Order) on October 28, 2022. The New Interim Measures Order renews, subject to certain operational modifications, Illumina’s obligations under the Initial Interim

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 and have an adverse impact on our ability to achieve the anticipated benefits of the Acquisition.

On December 1, 2021,January 10, 2023, we filed an action with the EU General Court asking for annulment of the InitialNew Interim Measures Order. The hearing ofOn January 20, 2023, the European Commission requested that application has beenthese proceedings be stayed pending our appeal ofon jurisdiction.

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. We believe that public statements made byOn 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 in connection withadopted the Prohibition Decision indicate that a subsequent decision is likely to be adopted by the European Commission that will order us to divest GRAIL (the EC Divestment Decision). Neither the Prohibition Decision nor such public statements indicate when any such EC Divestment Decision may be adopted.requiring us to (among other things) divest GRAIL and imposing the transitional measures. We intend to appeal the Prohibition Decision to the EU General Court by the applicable deadline. We also intend to appeal any EC Divestment Decision (if and when adopted by the European Commission) and, if necessary, to seek interim relief suspending the divestment of GRAIL until the final determination of these appeals.Decision.
The Prohibition Decision, and 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, willhave 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 being required to divest 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 millionmillion). In addition, any such divestment will likely implicate certain provisions in our third-party contracts and $1 billion).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.
Furthermore, even if an order or decision by the European Commission, General Court of EU, FTC or any other governmental or regulatory authority, approves the Acquisition, the delay in the approval or/and the imposition of conditions not part of the Acquisition agreement, could adversely affect the synergies and benefits we anticipate from the integration of GRAIL in our operations and may result in loss of revenue and other adverse effects on our business, financial condition and results of operations.
The Initial Interim Measures Order, the New Interim Measures Order, the Prohibition Decision, and the implementation of the EC Divestment Decision, or an FTC Divestment Decision or any other order or decision by any other governmental or regulatory authority, if implemented once final and non-appealable or during the pendency of the applicable appeals proceedings, have in the past and could may also in the future divert management’s attention and company resources away from existing operations and other opportunities that may have been beneficial to us, 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. 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.
Additionally, onOn July 19, 2022,12, 2023, the European Commission issuedadopted a Statement of Objections allegingfinal decision finding that we breached the EU Merger Regulation by, completingin its view, acquiring the Acquisition. We believe thatpossibility 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 will likely seek to imposetherefore imposed a fine on us pursuant to Article 14(2)(b) of the EU Merger Regulation of up to

approximately €432 million, representing the maximum fine of 10% of our consolidated annual revenues (the Article 14(2)(b) Fine).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 October 1, 2023, we accrued $458 million, including related foreign currency gains, included in accrued liabilities. In addition, the European Commission, the FTC and/or other governmental or regulatory authorities may seek to impose other fines, penalties, remedies or restrictions. We intend to vigorously defend against any such fines, penalties, remedies or restrictions, but we cannot predict the scope or severity thereof or the outcome of any related proceedings. We also 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 acquisitions and/or divestitures may result from our decision to proceed with the completion of the Acquisition. We expect to continue to hold the assets or equity interests of GRAIL separate until the applicable legal and regulatory proceedings are completed or, if required, a divestment of GRAIL is effected, and such inability to integrate may materially and adversely affect or prevent the synergies and other benefits we expect to achieve as a result of the Acquisition and could result in additional costs or liabilities, loss of revenue and other adverse effects on our business, financial condition and results of operations. In the second fiscal quarter of 2022, we accrued $453 million in anticipation of a potential Article 14(2)(b) Fine, included in accrued liabilities, representing 10% of our consolidated annual revenues for fiscal year 2021 in accordance with ASC 450, Contingencies. 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.
Adverse economic or market conditions may harm our business.
Worsening economic conditions, including inflation, increasing interest rates, decreasing economic activity, volatility in equity and credit markets or other changes in the economic environment, may adversely affect our business, financial condition, or results of operations. For example,Furthermore, we depend on third-party manufacturers and suppliers for some of our products, or sub-assemblies, components, and materials used in our products, and the suppliers of these inputs may seek to raise prices in the current inflationary economic environment. If our costs increase and we are unable to successfully pass along those increased costs to our customers, our revenue and or operating profitability may be adversely affected. In addition, we have a variable-interest-rate credit facility (see “Note 4. Debt”), under which we have no currently outstanding debt, and we may in the future raise additional debt or refinance existing debt. Our cost of borrowing in the future may be higher than it has been to date because interest rates have risen and may continue to increase. An increased costbecome 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 borrowingan 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; and (iii) the filing of a stockholder derivative and class action complaint captioned Icahn Partners LP, et al. v. deSouza, et al.. The 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 “7. Legal Proceedings” for further details. In the event that any of the matters described above result in one or more adverse judgments or settlements, we may adversely affectexperience an adverse impact on our financial condition, and results of operations.operations or stock price.
