ILLUMINA INC

Previous wording

The decrease in Core Illumina consumables revenue in 2023 was primarily due to a decrease in sequencing consumables revenue of $127 million, driven primarily by lower NovaSeq 6000 consumables pull-through as some of our high throughput customers transition to NovaSeq X, as well as the impact of macroeconomic conditions on customer purchasing power and project planning. Core Illumina instruments revenue decreased in 2023, primarily due to a decrease in sequencing instruments revenue of $23 million, which was driven by fewer shipments of our NovaSeq 6000, NextSeq and MiSeq instruments, partially offset by shipments of NovaSeq X that launched in the beginning of 2023. Core Illumina service and other revenue increased in 2023 primarily due to increased revenue from extended maintenance service contracts on a growing installed base. Additionally, Core Illumina revenue was adversely impacted by $7 million in 2023 due to foreign exchange rate fluctuations, which included $18 million reclassified to revenue in 2023 related to our cash flow hedges.

Current wording

Core Illumina consumables revenue increased in 2024 primarily due to an increase in sequencing consumables revenue of $59 million, driven primarily by an increase in NovaSeq X consumables, partially offset by decreases in consumables across our other high-throughput instruments, as customers transition to NovaSeq X, and across our mid-throughput instruments. Core Illumina instruments revenue decreased in 2024 primarily due to a decrease in sequencing instruments revenue of $203 million, driven by fewer shipments of our high-throughput instruments, following the first year of NovaSeq X shipments in 2023, and fewer shipments of our mid-throughput instruments, as capital and cash flow constraints continue to impact our customer’s purchasing behavior. Core Illumina service and other revenue increased in 2024 primarily due to increased revenue from strategic partnerships and extended maintenance service contracts, partially offset by decreased revenues from genotyping services and development and licensing agreements.

Previous wording

Core Illumina impairment for 2023 consisted of an IPR&D intangible asset impairment. GRAIL impairment for 2023 consisted of goodwill impairment of $712 million and an IPR&D intangible asset impairment of $109 million as a result of an interim impairment test performed in Q3 2023. GRAIL impairment for 2022 consisted of goodwill impairment of $3,914 million. See note “4. Acquisitions, Goodwill, and Intangible Assets” for additional details.

Current wording

GRAIL goodwill and intangible impairment in 2024 consisted of goodwill impairment of $1,466 million and IPR&D impairment of $420 million as a result of impairment tests performed in Q2 2024. Core Illumina goodwill and intangible impairment for 2024 consisted of an IPR&D impairment recorded in Q1 2024. GRAIL goodwill and intangible impairment for 2023 consisted of goodwill impairment of $712 million and IPR&D impairment of $109 million as a result of an interim impairment test performed in Q3 2023. See note 5. Goodwill, Intangible Assets, and Acquisitions.

Previous wording

Core Illumina legal contingency and settlement for 2023 consisted of an adjustment to our accrual for the fine imposed by the European Commission in July 2023 and accrued interest on the fine of $5 million, as well as a gain and a loss on two separate patent litigation settlements. Core Illumina legal contingency and settlement for 2022 primarily consisted of an accrual for the fine imposed by the European Commission and a net loss of $145 million related to the settlement of our litigation with BGI. See note “8. Legal Proceedings” for additional details.

Current wording

Core Illumina legal contingency and settlement in 2024 primarily consisted of a gain recognized in Q3 2024 of $489 million for the reversal of the EC fine accrual, and related accrued interest, following the European Commission’s decision to withdraw its previously imposed fine. Core Illumina legal contingency and settlement for 2023 primarily consisted of an adjustment to our accrual for the fine previously imposed by the European Commission and other patent litigation settlement activity. See note 9. Legal Proceedings for additional details.

Previous wording

Total other expense, net primarily relates to Core Illumina for both periods presented.

Current wording

Total other expense, net primarily relates to the Core Illumina segment.

Previous wording

Interest income consisted primarily of interest on our money market funds, which benefited from higher yields in 2023 due to rising interest rates. Interest expense consisted primarily of interest on our Term Notes and increased in 2023 due to the issuance of our 2025 and 2027 Term Notes in December 2022. The decrease in other expense, net was primarily due to a decrease in net losses recognized on our strategic investments of $82 million (net loss on our strategic investments of $40 million in 2023 compared to a net loss of $122 million in 2022), a favorable impact related to our Helix contingent value right (unrealized gain of $10 million in 2023 compared to an unrealized loss of $7 million in 2022), and a favorable impact related to our deferred compensation plan assets, partially offset by a net unrealized foreign currency loss related to the fine imposed by the European Commission.

Current wording

Interest income consisted primarily of interest on our money market funds, which decreased in 2024 primarily due to a lower cash balance throughout the year, as compared to prior year, partially offset by an increase in average interest rates. Interest expense consisted primarily of interest on our outstanding term debt, including on our delayed draw term loan, and a loss on debt extinguishment of $5 million related to the repayment of our delayed draw term loan. The increase in other expense, net in 2024 was primarily driven by an increase in net losses recognized on our strategic investments of $272 million, which included an unrealized loss of $309 million on our retained investment in GRAIL subsequent to the Spin-Off. This was offset by a favorable net impact related to foreign currency activity, as compared to the prior year, and an increase of $5 million in the gains recognized on our Helix contingent value right, which was settled in Q3 2024.

Previous wording

In 2022, the variance from the U.S. federal statutory tax rate of 21% was primarily because of the $822 million income tax expense impact from the impairment of goodwill and the $96 million income tax expense impact from the European Commission fine related to the GRAIL acquisition, both of which are nondeductible for tax purposes, the $87 million income tax expense impact of capitalizing research and development expense for tax purposes beginning in 2022, in accordance with the 2017 Tax Cuts and Jobs Act, and the $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. The income tax expense in 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.

Current wording

In 2024, the variance from the U.S. federal statutory tax rate of 21% was primarily because of the $308 million income tax expense impact from the impairment of goodwill, which is nondeductible for tax purposes, $90 million income tax expense impact of GRAIL pre-acquisition net operating losses on GILTI, the utilization of U.S. foreign tax credits, and the Pillar Two global minimum top-up tax, and the $52 million income tax expense impact of capitalizing research and development expenses for tax purposes. The income tax rate in 2024 was favorably impacted by the $99 million income tax expense impact of the reversal of the European Commission fine related to the GRAIL acquisition, which is excluded from taxable income, and by the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as in Singapore.

Previous wording

At December 31, 2023, we had approximately $1,048 million in cash and cash equivalents, of which approximately $386 million was held by our foreign subsidiaries. Cash and cash equivalents decreased by $963 million from the prior year 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 to finance our business needs as a supplement to cash provided by operating activities. As of December 31, 2023, we had $6 million remaining in short-term investments comprised of marketable equity securities.

Current wording

As of December 29, 2024, we had $1,127 million in cash and cash equivalents, of which approximately $439 million was held by our foreign subsidiaries. Cash and cash equivalents increased by $79 million from the prior year due primarily to 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. In 2024, we received net proceeds from the issuance of our 2026 Term Notes of $497 million and repaid our delayed draw term loan of $750 million. Our ability to generate cash from operations, supplemented with the issuance of debt and/or liquidation of our short-term investments, provides us with the financial flexibility we need to meet operating, investing, and financing needs. In connection with the Spin-Off, we derecognized GRAIL’s cash and cash equivalents of $968 million, which included the required Disposal Funding (see note 2. GRAIL Spin-Off). As of December 29, 2024, we had $93 million in short-term investments, comprised of marketable equity securities.

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, the consent of the extending lenders, and certain other conditions. As of December 31, 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.

Current wording

In January 2023, we entered into the Revolving Credit Agreement, 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.

Previous wording

As of December 31, 2023, the fair value of our contingent consideration liability related to our acquisition of GRAIL was $387 million, of which $385 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 2023 to be approximately $30 million and for related Covered Revenue Payments to total approximately $284,000 in Q1 2024. In 2023, we paid $803,000 in aggregate Covered Revenue Payments related to Covered Revenues for the periods Q4 2022 through Q3 2023 of $85 million in aggregate.

Current wording

As of December 29, 2024, the fair value of our contingent consideration liability related to GRAIL was $71 million, of which $70 million was included in other long-term liabilities. The contingent value rights 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 through August 2033. This reflects a 2.5% payment right to the first $1 billion of revenue each year for 12 years. Revenue above $1 billion each year is subject to a 9% contingent payment right during this same period. In 2024, we paid $1.1 million in aggregate Covered Revenue Payments related to Covered Revenues for the period Q4 2023 through Q3 2024 of $117 million in aggregate.

Previous wording

We had $3 million (plus recallable distributions of approximately $10 million), $46 million, and $47 million, respectively, remaining in our capital commitments to three venture capital investment funds as of December 29, 2024 that are callable through April 2026, July 2029, and December 2034, respectively.

Previous wording

The impact of the 2017 Tax Cuts and Jobs Act resulted in a one-time transition tax on earnings of certain foreign subsidiaries which we elected to pay in installments. As of December 31, 2023, we owed $71 million, which we expect to pay over the next two years.

Current wording

The impact of the 2017 Tax Cuts and Jobs Act resulted in a one-time transition tax on earnings of certain foreign subsidiaries which we elected to pay in installments. As of December 29, 2024, we owed $39 million, which we expect to pay within the next year.

Previous wording

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:

Our revenue is generated primarily from the sale of products and services. Product revenue primarily consists of sales of instruments and consumables used in genetic analysis. Service and other revenue primarily consists of revenue generated from genotyping and sequencing services, instrument service contracts, development and licensing agreements, and cancer detection testing services related to the GRAIL business.

Current wording

Our revenue is generated from the sale of products and services. Product revenue consists of sales of instruments and consumables used in genetic analysis. Service and other revenue consists of revenue generated from genotyping and sequencing services, instrument service contracts, development and licensing agreements, and, prior to the Spin-Off of GRAIL on June 24, 2024, cancer detection testing services related to the GRAIL business.

Previous wording

Revenue from product sales is recognized generally upon delivery to the end customer, which is when control of the product is deemed to be transferred. Invoicing typically occurs upon shipment and payment is typically due within 30 days from invoice. In instances where right of payment or transfer of title is contingent upon the customer’s acceptance of the product, revenue is deferred until all acceptance criteria have been met. Revenue from genotyping and sequencing services, including cancer detection testing services related to the GRAIL business, is recognized when earned, which is generally at the time the genotyping or sequencing analysis data is made available to the customer. Revenue from instrument service contracts is recognized as the services are rendered, typically evenly over the contract term. Revenue from development and licensing agreements generally includes upfront and periodic licensing fees, contract research and development services, or payments for development and regulatory milestones. Revenue for these agreements is recognized when each distinct performance obligation is satisfied.

In connection with certain acquisitions, contingent consideration can be earned by the sellers upon completion of certain future performance milestones. In these cases, a liability is recorded on the acquisition date, as a component of accrued liabilities and/or other long-term liabilities, for an estimate of the acquisition-date fair value of the contingent consideration. We generally use a Monte Carlo simulation or an income approach to estimate the fair value of contingent consideration. Estimates and assumptions used in a Monte Carlo simulation include forecasted revenues, a revenue risk premium, a revenue volatility estimate, an operational leverage ratio and a counterparty credit spread. An income approach utilizes inputs such as anticipated future cash flows, risk-free adjusted discount rates, and nonperformance risk, as well as management judgment regarding the probability of achieving certain future milestones. Future changes in our estimates could result in expenses or gains. Changes in the fair value of contingent consideration subsequent to the acquisition date are recognized in selling, general and administrative expense in our consolidated statements of operations.

Previous wording

We typically use the discounted cash flow method to value our acquired intangible assets. This method requires management judgment to forecast future operating results and establish residual growth rates and discount factors. The estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, we could experience impairment charges. In addition, we have estimated the economic lives of certain acquired assets and these lives are used to calculate depreciation and amortization expense. If our estimates of the economic lives change, depreciation or amortization expense could be accelerated or extended. We capitalize in-process research and development (IPR&D), which is considered indefinite lived until the completion or abandonment of the associated research and development efforts. Upon reaching the end of the relevant research and development project (i.e., upon commercialization), the IPR&D asset is amortized over its estimated useful life. If the relevant research and development project is abandoned, the IPR&D asset is expensed in the period of abandonment.

If our estimates of the economic lives change, depreciation or amortization expense could be accelerated or extended. We capitalize in-process research and development (IPR&D) with an indefinite life until completion or abandonment of the associated research and development efforts. Upon reaching the end of the research and development project (i.e., upon commercialization), the IPR&D asset is amortized over its estimated useful life. If the research and development project is abandoned, the IPR&D asset is expensed in the period of abandonment.

Previous wording

If the initial accounting for a business combination is incomplete by the end of a reporting period that falls within the measurement period (not to exceed a year from the date of acquisition), we report provisional amounts in our financial statements. During the measurement period, we adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. We record these adjustments to the provisional amounts with a corresponding offset to goodwill. Any adjustments identified after the measurement period are recorded in the consolidated statements of operations.
