ILLUMINA INC

To enhance comparability, the following table sets forth audited consolidated statement of operations data for 2024, 2023, and 2022, stated as a percentage of total revenue.(1)

(1)Percentages may not recalculate due to rounding.

Revenue

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.

The decrease in GRAIL revenue in 2024 was due to the Spin-Off in Q2 2024.

Gross Margin

*Not meaningful.

The increase in Core Illumina gross margin in 2024 was driven primarily by a favorable impact from the execution of our operational excellence initiatives that continue to deliver cost savings, including freight, and improve productivity, a more favorable revenue mix towards sequencing consumables, and a decrease in warranty and field service costs, partially offset by higher strategic partnership revenue that is lower margin.

The decrease in GRAIL gross loss in 2024 was due to the Spin-Off in Q2 2024.

Operating Expense

Core Illumina R&D expense decreased by $42 million, or 4%, in 2024 primarily due to decreases in headcount and employee compensation costs, and restructuring charges of $25 million, as we focus on cost reduction initiatives.

Core Illumina SG&A expense decreased by $348 million, or 28%, in 2024 primarily due to an increase in the gains recognized on our GRAIL contingent consideration liability of $290 million, a decrease in proxy contest charges of $30 million, and decreases in restructuring charges of $61 million, facility related costs, and employee compensation costs, as we continue to exit certain of our facilities and focus on our cost reduction initiatives. The decrease was partially offset by an increase in share-based compensation expense related to PSU awards.

The decrease in GRAIL R&D and SG&A expense in 2024 was due to the Spin-Off in Q2 2024.

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.

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.

Other Income (Expense)

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

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.

Provision for Income Taxes

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.

In 2023, the variance from the U.S. federal statutory tax rate of 21% was primarily because of the $149 million income tax expense impact from the impairment of goodwill, which is nondeductible for tax purposes, the $86 million income tax expense impact of capitalizing research and development expense for tax purposes, and the $61 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 2023 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.

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” in Risk Factors within the Business & Market Information section of this report, including future tax legislation that changes existing tax policies, laws, regulations, or rates.
