As explained in Note 1 and Note 7 to the consolidated financial statements, the Company assesses the valuation of inventory each reporting period. Obsolete inventory or inventory in excess of management's estimated usage requirement is written down to its estimated net realizable value if those balances are determined to be less than cost.Auditing management's estimates for excess and obsolete inventory involved subjective auditor judgment because the estimates rely on a number of factors that are affected by market and economic conditions. In particular, the excess and obsolete inventory calculations are subject to potential significant changes in assumptions about future demand, market conditions, and the release of new products that may supersede old ones.How We Addressed the Matter in Our AuditWe obtained an understanding, evaluated and tested the design and operating effectiveness of internal controls over the Company's excess and obsolete inventory valuation process, including management's assessment of the assumptions stated above and manual input and analysis of certain data underlying the excess and obsolete inventory valuation. Our audit procedures included, among others, evaluating the significant assumptions stated above and the accuracy and completeness of the underlying manual inputs provided by supply chain and operations management personnel used to value excess and obsolete inventory. We compared the balance of on-hand inventories to usage forecasts and historical usage and evaluated whether adjustments to forecasted usage were required for specific product considerations, such as new product introductions, technological changes or alternative uses.

These decisions, along with a continued and significant decrease in the Company’s stock price and market capitalization, required us to perform an interim impairment test in Q3 2022.

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 GRAIL and Core Illumina 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 discount rate selected was 22.0%. 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. In conjunction with our interim goodwill impairment test, we also evaluated GRAIL’s IPR&D intangible asset for potential impairment. We performed our 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.

The notes were convertible into cash, shares of common stock or a combination of cash and shares of common stock, at our election, based on conversion rates as defined in the indenture. The 2023 Convertible Notes matured on August 15, 2023, at which time the principal was repaid in cash. We did not issue any shares of common stock. The 2023 Convertible Notes were initially accounted for in accordance with authoritative guidance for convertible debt instruments that may be settled in cash upon conversion. The guidance required the carrying amount of the liability component to be estimated by estimating the fair value of a similar liability that does not have an associated conversion feature. Because at issuance we had no outstanding non-convertible public debt, we determined that market-traded senior, unsecured corporate bonds represented a similar liability without a conversion option. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies in our industry, and with similar maturities to the 2023 Convertible Notes, we estimated an implied interest rate of 3.7%, assuming no conversion option. The estimated implied interest rate was applied to the 2023 Convertible Notes, which resulted in a fair value of the liability component in aggregate of $624 million upon issuance, calculated as the present value of implied future payments based on the $750 million aggregate principal amount. The $126 million difference ($93 million, net of tax) between the aggregate principal amount of $750 million and the estimated fair value of the liability component was recorded in additional paid-in capital as the 2023 Convertible Notes were not considered redeemable. 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 consolidated balance sheets on January 3, 2022.

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. Before the filing of the complaint, the purported stockholders did not make a demand that our Board of Directors pursue the claims asserted therein. The complaint seeks damages, costs and expenses, including attorney fees, the certification and consolidation of a putative class, the issuance of amended disclosures, the removal of conflicted directors and declaratory and other equitable relief. On November 1, 2023, the defendants filed a motion to dismiss the complaint, which has not yet been briefed. On the same day, Illumina-joined by the director defendants-moved to strike portions of the complaint that contain improperly included confidential and privileged information. On January 16, 2024, the Court granted the motion to strike. On December 5, 2023, the plaintiffs moved to expedite the proceedings with respect to their direct claims. The director defendants opposed that motion and Illumina joined their opposition. On January 19, 2024, the Court denied plaintiffs’ motion to expedite. On January 23, 2024, the plaintiffs filed a motion for reargument of the Court’s January 16 opinion, which the Court denied on February 19, 2024. On February 29, 2024, the plaintiffs filed an application to the trial court to certify the orders granting the motion to strike and denying the motion for reargument for interlocutory appeal. The Court refused the application on March 20, 2024.

Revenue recognition for contracts with multiple deliverables is based on the separate satisfaction of each distinct performance obligation within the contract. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. The contract price is allocated to each performance obligation in proportion to its standalone selling price. We determine our best estimate of standalone selling price using average selling prices over a rolling 12-month period coupled with an assessment of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, we rely upon prices set by management, adjusted for applicable discounts. 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.

This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. Revenue recognition for contracts with multiple deliverables is based on the separate satisfaction of each distinct performance obligation within the contract. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. The contract price is allocated to each performance obligation in proportion to its standalone selling price. We determine our best estimate of standalone selling price using average selling prices over a rolling 12-month period coupled with an assessment of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, we rely upon prices set by management, adjusted for applicable discounts. 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. Revenue is recorded net of discounts, distributor commissions, and sales taxes collected on behalf of governmental authorities. Employee sales commissions are recorded as selling, general and administrative expense when incurred as the amortization period for such costs, if capitalized, would have been one year or less. In certain markets, products and services are sold to customers through distributors. In most sales through distributors, the product is delivered directly to customers by us.

We recognize revenue when control of our products and services is transferred to our customers in an amount that reflects the consideration we expect to receive from our customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. Revenue recognition for contracts with multiple deliverables is based on the separate satisfaction of each distinct performance obligation within the contract. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract.

If the product or service has no history of sales or if the sales volume is not sufficient, we rely upon prices set by management, adjusted for applicable discounts. 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.

This was partially offset by the implications of the U.S. tax legislation that was signed on July 4, 2025, which included changes to no longer require capitalization of U.S. based research and development expenses. While the changes from the recent U.S. tax legislation were favorable, based on available evidence, the increased U.S. tax deductions resulted in a determination that it is more likely than not the future realization of deferred tax assets associated with certain U.S. foreign tax credits may not be achieved. Therefore, a valuation allowance of $62 million was recorded against the deferred tax assets associated with certain U.S. foreign tax credits.

On a discretionary basis, we may also make employer contributions to participant accounts in any amount determined by us. The vesting schedules of employer contributions are at the sole discretion of the Compensation Committee. However, all employer contributions shall become 100% vested upon the occurrence of the participant’s disability, death or retirement or a change in control of Illumina. The benefits under this plan are unsecured. Participants are generally eligible to receive payment of their vested benefit at the end of their elected deferral period or after termination of their employment for any reason or at a later date to comply with the restrictions of Section 409A. 91 91 91 Table of ContentsILLUMINA, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Table of Contents" }, { "status": "MODIFIED", "current_title": "Use of Estimates", "prior_title": "Use of Estimates", "similarity_score": 0.852, "confidence": "high", "key_changes": [ "Reworded sentence: \"The preparation of the consolidated financial statements requires that management make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and disclosures of contingent assets and liabilities.\"" ], "current_body": "The preparation of the consolidated financial statements requires that management make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and disclosures of contingent assets and liabilities.

Prior to the Spin-Off of GRAIL in June 2024, our reporting units included Core Illumina and GRAIL. We performed a quantitative test for both reporting units. GRAIL’s carrying value exceeded its fair value, estimated as $580 million, and we recorded a goodwill impairment of $1,466 million. There was no impairment noted for Core Illumina. impairment To determine the fair value of GRAIL as of May 2024, we utilized enterprise value estimates of GRAIL, as estimated by investment bankers for purposes of determining pricing for the Spin-Off. Estimates and assumptions used to derive the investment bankers’ enterprise value estimates included estimated revenues for a two year period based on assumed growth rates and implied revenue multiples for comparable companies. These estimates and assumptions represent a Level 3 measurement as they are supported by little or no market activity and reflect our own assumptions in measuring fair value. An increase in estimated enterprise values for GRAIL of 100% would still have resulted in a full impairment of goodwill. In prior periods, we used a combination of both an income (discounted cash flow) and market approach to determine the fair value of GRAIL. The income approach utilized estimated cash flows for GRAIL based on a long-range plan, for a 15 year period, which contemplated FDA approval. Based on this approach, in Q3 2023, we estimated the fair value of GRAIL to be $3.6 billion and using this same approach in Q4 2023 suggested no further decrement in fair value. Initial analyst coverage of GRAIL from December 2023 into the spring of 2024 suggested that GRAIL could be valued between $3 billion and $4 billion. By May 2024, prior to the consummation of the GRAIL Spin-Off, additional information about GRAIL had become available in GRAIL’s amended Form 10 filings and a publicly available management presentation, which included updated disclosure about GRAIL’s business and anticipated near term financial trends. Prior to the consummation of the GRAIL Spin-Off, the amount of GRAIL’s Disposal Funding, $974 million, was also disclosed. Analyst and banker valuation estimates then began to estimate fair values between $400 million and $770 million, consistent with the impairment recorded in Q2 2024. To determine the fair value of Core Illumina, we used a combination of both an income and market approach consistent with prior periods. The income approach utilized estimated discounted cash flows for the 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 and represent a Level 3 measurement because they are supported by little or no market activity and reflect our own assumptions in measuring fair value. 72 72 72 Table of ContentsILLUMINA, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Table of Contents", "prior_body": "We recognize revenue when control of our products and services is transferred to our customers in an amount that reflects the consideration we expect to receive from our customers in exchange for those products and services. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. Revenue recognition for contracts with multiple deliverables is based on the separate satisfaction of each distinct performance obligation within the contract. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. The contract price is allocated to each performance obligation in proportion to its standalone selling price. We determine our best estimate of standalone selling price using average selling prices over a rolling 12-month period coupled with an assessment of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, we rely upon prices set by management, adjusted for applicable discounts. 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 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. In September 2024, the European Commission withdrew its previously imposed fine of €432 million. Accordingly, we reversed the related accrual and recognized a net gain of $481 million in Q3 2024. The guarantees we provided in October 2023 to satisfy the obligation in lieu of cash payment while we appealed the European Commission’s jurisdictional and fine decisions are no longer outstanding. Refer to note 9. Legal Proceedings for additional details. In June 2024, we entered into a 364-day Delayed Draw Credit Facility, which provided us with a senior unsecured term loan credit facility in an aggregate principal amount of up to $750 million. On June 20, 2024, we borrowed $750 million on the Delayed Draw Credit Facility. The delayed draw term loan incurred interest at a rate of 6.7%. On September 9, 2024, we repaid the full principal amount outstanding under the Delayed Draw Credit Facility, as well as accrued interest, in an aggregate amount of $761 million and terminated the Delayed Draw Credit Agreement. On September 9, 2024, we issued $500 million aggregate principal amount of 2026 Term Notes. We received net proceeds of $497 million, which were used to repay a portion of the outstanding debt under the Delayed Draw Credit Agreement. The 2026 Term Notes, which mature on September 9, 2026, accrue interest at a rate of 4.650% per annum, payable semi-annually on March 9 and September 9 of each year, beginning on March 9, 2025. We may redeem for cash all or any portion of the 2026 Term Notes, at our option, at any time prior to maturity. In December 2022, we issued $500 million aggregate principal amount of 2025 Term Notes and $500 million aggregate principal amount of 2027 Term Notes. 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. In March 2021, we issued $500 million aggregate principal amount of 2031 Term Notes, which mature on March 23, 2031 and 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 2025, 2027, or 2031 Term Notes, at our option, at any time prior to maturity. 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. The credit facility matures, and all amounts outstanding 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 29, 2024, there were no outstanding borrowings. 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. In August 2024, our Board of Directors authorized a new share repurchase program, which cancels and supersedes all prior and available repurchase authorizations, to repurchase up to $1.5 billion of our outstanding common stock. The repurchases may be completed through open market purchases, pursuant to Rule 10b5-1 or Rule 10b-18, or through an accelerated share repurchase program. Authorizations to repurchase up to $1.4 billion of our outstanding common stock remained available as of December 29, 2024. Subsequent to December 29, 2024 and through February 11, 2025, we repurchased an additional 1.0 million shares of our common stock for $126 million. 38 38 38 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. 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. Our other short-term and long-term material cash requirements, from known contractual obligations as of December 29, 2024, include operating lease liabilities, uncertain tax positions, and amounts due under our executive deferred compensation plan, as discussed in the Consolidated Financial Statements section of this report. 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 Revolving 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, may 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; •potential strategic acquisitions and investments; •repayment of debt obligations; •repurchases of our outstanding common stock; and •the evolving needs of our facilities, including costs of leasing and building out facilities. We expect that our revenue and results of operations, 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." }, { "status": "MODIFIED", "current_title": "NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)", "prior_title": "NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)", "similarity_score": 0.824, "confidence": "high", "key_changes": [ "Reworded sentence: \"A summary of the restructuring liability is as follows: In millionsEmployee Separation CostsOther CostsTotalAmount recorded in accrued liabilities as of December 31, 2023$17 $1 $18 Expense recorded12 4 16 Cash payments(24)(2)(26)Adjustments to accrual(3)(1)(4)Amount recorded in accrued liabilities as of December 29, 20242 2 4 Expense recorded47 — 47 Cash payments(42)(2)(44)Adjustments to accrual— — — Amount recorded in accrued liabilities as of December 28, 2025$7 $— $7\"" ], "current_body": "We recognize revenue when control of our products and services is transferred to our customers in an amount that reflects the consideration we expect to receive from our customers in exchange for those products and services.

This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. Revenue recognition for contracts with multiple deliverables is based on the separate satisfaction of each distinct performance obligation within the contract. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. The contract price is allocated to each performance obligation in proportion to its standalone selling price. We determine our best estimate of standalone selling price using average selling prices over a rolling 12-month period coupled with an assessment of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, we rely upon prices set by management, adjusted for applicable discounts. 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 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.

This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. Revenue recognition for contracts with multiple deliverables is based on the separate satisfaction of each distinct performance obligation within the contract. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. We consider a performance obligation satisfied once we have transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. The contract price is allocated to each performance obligation in proportion to its standalone selling price. We determine our best estimate of standalone selling price using average selling prices over a rolling 12-month period coupled with an assessment of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, we rely upon prices set by management, adjusted for applicable discounts. 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. Revenue is recorded net of discounts, distributor commissions, and sales taxes collected on behalf of governmental authorities. Employee sales commissions are recorded as selling, general and administrative expense when incurred as the amortization period for such costs, if capitalized, would have been one year or less.

PSU that do not include a market condition represent a right to receive a certain number of shares of common stock based on the achievement of corporate performance goals and continued employment during the vesting period.

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 (through August 2033). 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 the periods Q4 2023 through Q3 2024, Q4 2022 through Q3 2023, and Q4 2021 through Q3 2022 were $117 million, $85 million, and $42 million, respectively, driven primarily by sales of GRAIL’s Galleri test. Covered Revenue Payments relating to such periods were $1.1 million, $803,000, and $396,000 in 2024, 2023, and 2022, respectively. A portion of the Covered Revenue Payments in 2022 were applied to reimburse us for certain expenses. The fair value of our contingent consideration liability related to GRAIL was $71 million and $387 million as of December 29, 2024 and December 31, 2023, respectively, of which $70 million and $385 million, respectively, was included in other long-term liabilities, with the remaining balances included in accrued liabilities. We use a Monte Carlo simulation to estimate the fair value of the GRAIL contingent consideration liability. 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. Subsequent to the Spin-Off, we no longer have access to GRAIL management’s forecasts. Therefore, we must rely on information made public by GRAIL’s management and, beginning in Q4 2024, information published in analyst reports to estimate forecasted revenues through August 2033. In August 2024, GRAIL publicly announced a corporate restructure, including a reduction in headcount and planned hires and a substantial decrease in certain R&D projects and investments. To estimate the liability as of December 29, 2024, we selected a revenue risk premium of 9%, which was derived from reconciling our forecasted revenues for GRAIL to GRAIL’s market capitalization based on a 60-day trailing average. The significant decrease in the contingent consideration liability from December 31, 2023 was due to a decrease in the forecasted revenues, following revised revenue projections announced by GRAIL in May 2024 and the restructuring announcement in August 2024. 69 69 69 Table of ContentsILLUMINA, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Table of Contents" }, { "status": "MODIFIED", "current_title": "Derivative Financial Instruments", "prior_title": "Derivative Financial Instruments", "similarity_score": 0.716, "confidence": "medium", "key_changes": [ "Reworded sentence: \"64 64 64 Table of ContentsILLUMINA, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Table of Contents\"" ], "current_body": "We are exposed to foreign exchange rate risks in the normal course of business and use derivative financial instruments to partially offset this exposure.

Revenue recognition for contracts with multiple deliverables is based on the separate satisfaction of each distinct performance obligation within the contract. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract.

We determine our best estimate of standalone selling price using average selling prices over a rolling 12-month period coupled with an assessment of current market conditions. If the product or service has no history of sales or if the sales volume is not sufficient, we rely upon prices set by management, adjusted for applicable discounts. 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.

Throughout 2025, we experienced several headwinds including macroeconomic factors such as tariffs, inflation, exchange rate fluctuations and concerns about an economic downturn, competitive challenges in our China region, the sanctions imposed on Russia as a result of the armed conflict between Russia and Ukraine, and reductions in the U.S. government’s funding of the NIH, all of which have impacted both Illumina directly and our customers’ behavior. For example, some customers, specifically research customers, continue to manage inventory and capital more conservatively and some labs are delaying projects due to funding concerns. Additionally, in early 2025, we were added to the unreliable entities list by regulatory authorities in China. See the risk factor “Regulatory authorities in China have added Illumina to the List of Unreliable Entities” in Risk Factors within the Business & Market Information section of this report for additional information. We expect these factors to continue to impact our sales and results of operations in 2026 and beyond, the size and duration of which is significantly uncertain. Beginning in April 2025, the U.S. government and several other countries enacted tariffs. Under the current tariff environment, the largest cost impact to us relates to importation from our manufacturing facility in Singapore. The remainder is a mix of importation of parts and sub-assemblies to our manufacturing operations in the United States and importation into China. We have and will continue to take several actions to fully mitigate the impact of these tariffs, and we partially mitigated the impact in 2025, through supply chain optimization, cost measures, and pricing actions. Based on the current tariff environment, our aim is to more fully mitigate the impact in 2026. Despite these challenges, we made significant progress towards our strategic goals in achieving revenue growth and improving operating margins in 2025. During 2025, we focused on our operational excellence initiatives to improve productivity and achieve cost savings and on our capital allocation strategy, including significant share repurchases. In early 2025, we also implemented an incremental $100 million cost reduction program for 2025, including optimizing stock-based compensation and non-labor spending and accelerating certain productivity measures, as well as workforce reductions, to help mitigate the expected impact of a reduction in revenue and related operating income from our Greater China business, as a result of being added to the List of Unreliable Entities, and the uncertainty in the U.S. government’s funding of the NIH. We expect to make further progress towards our strategic goals in 2026. 34 34 34 Financial highlights for 2025 included the following: •Core Illumina revenue was $4.34 billion in 2025 and relatively flat compared to revenue of $4.33 billion in 2024. Consumables revenue increased primarily due to demand for high-throughput consumables, partially offset by decreased service and other revenue, primarily due to decreased revenue from our strategic partnerships, and a decrease in instruments revenue, primarily due to fewer shipments of our high- and mid-throughput sequencing instruments. Total revenue in 2025 was impacted, across all products and services, by a decrease in revenue in our Greater China region of $65 million, primarily due to our inclusion on the List of Unreliable Entities. Consolidated revenue decreased 1% in 2025 to $4.34 billion compared to $4.37 billion in 2024 primarily due to a decrease in service and other revenue, driven by a decrease in GRAIL service and other revenue of $55 million as a result of the Spin-Off in 2024. •Core Illumina gross margin was 66.1% in 2025 compared to 67.1% in 2024. Gross margin decreased primarily due to higher costs related to tariffs and a $23 million intangible asset impairment, partially offset by lower strategic partnership revenue, that is lower margin, and a more favorable product mix towards consumables. Consolidated gross margin was 66.1% in 2025 compared to 65.4% in 2024, and the increase was driven by the Spin-Off of GRAIL in 2024. 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; tariffs; and product support obligations. •Core Illumina income from operations was $807 million in 2025 compared to $1,473 million in 2024. Total operating expense increased $628 million and gross profit decreased $39 million. The increase in Core Illumina operating expense was primarily due to a gain of $456 million recognized in 2024 for legal contingency and settlement, primarily related to the withdrawn European Commission fine, and a gain recognized on our contingent consideration liabilities, primarily related to the GRAIL CVRs, of $315 million, partially offset by a decrease in acquisition-related costs, which included $53 million in 2024 directly related to the GRAIL Spin-Off. Excluding these impacts, Core Illumina operating expense decreased in 2025, primarily due to our continued focus on our operational excellence and cost reduction initiatives to accelerate growth and expand operating margins. Consolidated income from operations was $807 million in 2025 compared to a loss of $833 million in 2024. Total operating expense decreased $1,631 million and gross profit increased $9 million. The decrease in operating expense was primarily driven by a decrease in GRAIL operating expense of $2,267 million due to the Spin-Off in 2024, primarily related to the $1,886 million goodwill and intangible asset impairments recognized in 2024. •Our effective tax rate was 21.7% and (3.8)% in 2025 and 2024, respectively. The variance from the U.S. federal statutory tax rate of 21% was primarily due to the net change to valuation allowances against certain deferred tax assets in the U.S. and Singapore. The income tax rate in 2025 was favorably impacted by the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as Singapore. •We ended 2025 with cash, cash equivalents, and short-term investments totaling $1,633 million, of which approximately $444 million was held by our foreign subsidiaries. 35 35 35", "prior_body": "Since 2023, macroeconomic factors such as inflation, exchange rate fluctuations and concerns about an economic downturn, competitive challenges in our China region, and the sanctions imposed on Russia as a result of the armed conflict between Russia and Ukraine have impacted both Illumina directly and our customers’ 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 have an impact on our sales and results of operations in 2025, the size and duration of which is significantly uncertain. In February 2025, we were added to China’s Ministry of Commerce List of Unreliable Entities, the implications of which are currently uncertain. See the risk factor “China’s Ministry of Commerce has added Illumina to its List of Unreliable Entities” in Risk Factors within the Business & Market Information section of this report for additional information. During 2024, we made significant progress towards our strategic goals to accelerate growth and expand operating margins. We focused on operational excellence initiatives, to improve productivity and achieve cost savings, and on our capital allocation strategy, including obtaining authorization for a new share repurchase program. We expect to continue to make further progress towards these goals in 2025, including a focus on returning to revenue growth. Financial highlights for 2024 included the following: •Revenue decreased 3% in 2024 to $4.4 billion compared to $4.5 billion in 2023 primarily due to a decrease in sequencing instruments revenue, driven by fewer shipments of our high-throughput and mid-throughput instruments, offset by increases in sequencing consumables revenue. •Gross profit as a percentage of revenue (gross margin) was 65.4% in 2024 compared to 60.9% in 2023. The increase in gross margin was driven primarily by 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. This was partially offset by higher strategic partnership revenue that is lower margin. 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. 32 32 32 •Loss from operations was $0.8 billion in 2024 compared to $1.1 billion in 2023. The decrease was due to a decrease in operating expense of $119 million and an increase in gross profit of $117 million. The decrease in operating expense included a $476 million favorable impact in legal contingency and settlement, as a result of the European Commission withdrawing, in September 2024, its previously imposed fine, a decrease of $323 million in GRAIL operating expenses, as a result of the Spin-Off in Q2 2024, an increase in the gains recognized on our GRAIL contingent consideration liability of $290 million, and a decrease in restructuring charges of $86 million, offset by an increase in goodwill and intangible impairment of $1,062 million. We continue to focus on our cost reduction initiatives to accelerate progress toward higher margins and create flexibility for further investment in high-growth areas. •Our effective tax rate was (3.8)% and (3.9)% in 2024 and 2023, respectively. In 2024, the variance from the U.S. federal statutory tax rate of 21% was primarily because of the income tax expense impact of the impairment of goodwill, which is nondeductible for tax purposes, the income tax expense impact of the reversal of the European Commission fine related to the GRAIL acquisition, which is excluded from taxable income, 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, the utilization of U.S. foreign tax credits, and the Pillar Two global minimum top-up tax. 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. •We ended 2024 with cash, cash equivalents, and short-term investments totaling $1,220 million, of which approximately $439 million was held by our foreign subsidiaries. 33 33 33" }, { "status": "MODIFIED", "current_title": "Operating Expense", "prior_title": "Operating Expense", "similarity_score": 0.611, "confidence": "medium", "key_changes": [ "Reworded sentence: \"2025-2024Dollars in millions20252024Change% ChangeResearch and development:Core Illumina$967 $988 $(21)(2)%GRAIL— 189 (189)(100)Eliminations— (8)8 (100)Consolidated research and development967 1,169 (202)(17)Selling, general and administrative:Core Illumina1,086 900 186 21 GRAIL— 192 (192)(100)Consolidated selling, general and administrative1,086 1,092 (6)(1)Goodwill and intangible impairment:Core Illumina— 3 (3)(100)GRAIL— 1,886 (1,886)(100)Consolidated goodwill and intangible impairment— 1,889 (1,889)(100)Legal contingency and settlement:Core Illumina10 (456)466 (102)Total consolidated operating expense$2,063 $3,694 $(1,631)(44)% 2025-2024 Core Illumina R&D expense decreased by $21 million, or 2%, in 2025 primarily due to decreases in employee-related compensation costs, including share-based compensation expense related to our optimization efforts, and a decrease in outside professional services, partially offset by an increase in restructuring charges of $14 million.\"" ], "current_body": "2025-2024Dollars in millions20252024Change% ChangeResearch and development:Core Illumina$967 $988 $(21)(2)%GRAIL— 189 (189)(100)Eliminations— (8)8 (100)Consolidated research and development967 1,169 (202)(17)Selling, general and administrative:Core Illumina1,086 900 186 21 GRAIL— 192 (192)(100)Consolidated selling, general and administrative1,086 1,092 (6)(1)Goodwill and intangible impairment:Core Illumina— 3 (3)(100)GRAIL— 1,886 (1,886)(100)Consolidated goodwill and intangible impairment— 1,889 (1,889)(100)Legal contingency and settlement:Core Illumina10 (456)466 (102)Total consolidated operating expense$2,063 $3,694 $(1,631)(44)% 2025-2024 Core Illumina R&D expense decreased by $21 million, or 2%, in 2025 primarily due to decreases in employee-related compensation costs, including share-based compensation expense related to our optimization efforts, and a decrease in outside professional services, partially offset by an increase in restructuring charges of $14 million.

Restricted stock units (RSU) and performance stock units (PSU) are both considered restricted stock. The determination of the amount of share-based compensation expense for our PSU requires the use of certain estimates and assumptions that affect the amount of share-based compensation expense recognized in our consolidated statements of operations. The fair value of restricted stock and performance stock units that do not include a market condition is determined by the closing market price of our common stock on the date of grant. PSU that do not include a market condition represent a right to receive a certain number of shares of common stock based on the achievement of corporate performance goals and continued employment during the vesting period. At each reporting period, we reassess the probability of the achievement of such corporate performance goals and any increase or decrease in share-based compensation expense resulting from an adjustment in the estimated shares to be released is treated as a cumulative catch-up in the period of adjustment. The fair value of performance stock units that include a market condition is determined on the date of grant using a Monte Carlo simulation, which includes assumptions for expected volatility, risk-free interest rate and dividend yield. 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. Share-based compensation expense is recognized based on the fair value on a straight-line basis over the requisite service periods of the awards.

The fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants, are based on estimates and assumptions determined by management. These valuations require us to make estimates and assumptions, especially with respect to intangible assets. We record the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, as goodwill. Costs that we incur to complete the business combination, such as legal and other professional fees, are expensed as they are incurred. 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. We typically use a discounted cash flow method to value 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 the acquired assets, which 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) 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. 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 one year from the date of acquisition), we report provisional amounts in our consolidated 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.

Events that would indicate impairment and trigger an interim impairment test include, but are not limited to, current economic and market conditions, including a decline in market capitalization, a significant adverse change in legal factors, business climate or operational performance of the business, and an adverse action or assessment by a regulator. We perform our goodwill impairment analysis at the reporting unit level, which aligns with our reporting structure and availability of discrete financial information.

If, after assessing the totality of these qualitative factors, we determine that it is not more likely than not that the fair values of our reporting units are less than the carrying amounts, then no additional assessment is deemed necessary.

Reimbursement by a payor may depend on a number of factors, including a payor's determination that tests using our technologies are: not experimental or investigational; medically necessary; appropriate for the specific patient; cost-effective; supported by peer-reviewed publications; and included in clinical practice guidelines. Since each third-party payor often makes independent reimbursement decisions and may also make decisions on an individual patient basis, obtaining such approvals is a time-consuming and costly process that requires Illumina and/or our customers to provide scientific and clinical data supporting the clinical benefits of each of our products. As a result, there can be no assurance that reimbursement approvals will be obtained. This process can delay the broad market introduction of new products, and could have a negative effect on our results of operations. As a result, third-party reimbursement may not be consistent or financially adequate to cover the cost of diagnostic products that we develop, market, or sell. This could limit our ability to sell our products or cause us to reduce prices, which would adversely affect our results of operations. Even if tests are reimbursed, third-party payors may withdraw their coverage policies, cancel their contracts with our customers at any time, review and adjust the rate of reimbursement, require co-payments from patients, or stop paying for tests, which would reduce our revenues. In addition, insurers, including managed care organizations as well as government payors such as Medicare and Medicaid, have increased their efforts to control the cost, utilization, and delivery of healthcare services. These measures have resulted in reduced payment rates and decreased utilization for the clinical laboratory industry. Reductions in the reimbursement rate of payors may occur in the future. Reductions in the prices at which our tests are reimbursed could have a negative impact on our results of operations. 18 18 18" }, { "status": "UNCHANGED", "current_title": "If product or service liability lawsuits are successfully brought against us, we may face reduced demand for our products and incur significant liabilities.", "prior_title": "If product or service liability lawsuits are successfully brought against us, we may face reduced demand for our products and incur significant liabilities.", "current_body": "Our products and services are used for sensitive applications, and we face an inherent risk of exposure to product or service liability claims if our products or services are alleged to have caused harm, resulted in false negatives or false positives, or do not perform in accordance with specifications.

The fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants, are based on estimates and assumptions determined by management. These valuations require us to make estimates and assumptions, especially with respect to intangible assets. We record the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, as goodwill. Costs that we incur to complete the business combination, such as legal and other professional fees, are expensed as they are incurred. 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. We typically use a discounted cash flow method to value 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 the acquired assets, which 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) 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. 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 one year from the date of acquisition), we report provisional amounts in our consolidated 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. 44 44 44" }, { "status": "UNCHANGED", "current_title": "Any inability to effectively protect our proprietary technologies could harm our competitive position.", "prior_title": "Any inability to effectively protect our proprietary technologies could harm our competitive position.", "current_body": "The proprietary positions of companies developing tools for the life sciences, genomics, forensics, agricultural, and pharmaceutical industries, including our proprietary position, generally are uncertain and involve complex legal and factual questions. Our success depends to a large extent on our ability to develop proprietary products and technologies and to obtain patents and maintain adequate protection of our intellectual property in the United States and other countries. The laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and many companies have encountered significant challenges in establishing and enforcing their proprietary rights outside of the United States. These challenges can be caused by the absence of rules and methods for the establishment and enforcement of intellectual property rights outside of the United States. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. Any finding that our patents or applications are unenforceable could harm our ability to prevent others from practicing the related technology, and a finding that others have inventorship or ownership rights to our patents and applications could require us to obtain certain rights to practice related technologies, which may not be available on favorable terms, if at all. Furthermore, as issued patents expire, including those related to our sequencing-by-synthesis technology, we may lose some competitive advantage as others develop, market, and sell competing products, which could negatively affect our revenue. 21 21 21 In addition, our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products and may therefore fail to provide us with any competitive advantage. We may need to initiate lawsuits to protect or enforce our patents, or litigate against third-party claims, which would be expensive, and, if we lose, may cause us to lose some of our intellectual property rights and reduce our ability to compete in the marketplace. Furthermore, these lawsuits may divert the attention of our management and technical personnel. There is also the risk that others may independently develop similar or alternative technologies or design around our patented technologies. In that regard, certain patent applications in the United States may be maintained in secrecy until the patents issue, and publication of discoveries in the scientific or patent literature tend to lag behind actual discoveries by several months. We also rely upon trade secrets and proprietary know-how protection for our confidential and proprietary information, and we have taken security measures to protect this information. These measures, however, may not provide adequate protection for our trade secrets, know-how, or other confidential information. Additionally, the use of artificial intelligence (AI) based software is increasingly common. Use of AI based software may lead to the inadvertent release of confidential proprietary information which may impact our ability to realize the benefit of our intellectual property.

In particular, collaboration agreements and large-scale government funded projects such as population genomic projects are the result of lengthy and complex negotiations, and the timing of revenue recognition in connection with these agreements and projects may be subject to significant uncertainty because of the long-term nature of development and collaboration projects, as well as sample availability for population genomics projects.

As a substantial portion of our quarterly revenue is typically recognized in the last month of the quarter with a concentration of orders in the final weeks, our manufacturing and shipping operations may experience increased pressure and demand during the time period shortly before the end of a fiscal quarter; delays related to our manufacturing and shipping operations during this time period could delay the recognition of revenue. From time to time, we receive large orders that have a significant effect on our operating results in the period in which the order is recognized as revenue. The timing of such orders is difficult to predict, and the timing of revenue recognition from such orders may affect period-to-period changes in net sales.

To achieve these objectives, our policy allows us to maintain a portfolio of cash equivalents and short-term investments in a variety of securities, including money market funds, U.S. Treasury debt and corporate debt securities. Our policy also limits the amount of credit exposure to any one issuer and type of instrument. Under our current policies, we do not use interest rate derivative instruments to manage exposure to interest rate changes. As of December 28, 2025, our cash equivalents consisted primarily of U.S. government money market funds that invest in very liquid investments, namely, cash, government securities and purchase agreements that are collateralized fully with government securities. U.S. government money market funds provide same day liquidity and have a net asset value of $1.00. We have historically maintained a relatively short average maturity for our investment portfolio, and we believe a hypothetical 100 basis point adverse move in interest rates along the entire interest rate yield curve would not materially affect the fair value of our interest-sensitive financial instruments. Other than convertible notes and SAFEs, we held no debt securities as of December 28, 2025. In November 2025, we issued $500 million of 4.750% notes due 2030. In September 2024, we issued $500 million of 4.650% notes due 2026. In December 2022, we issued $500 million of 5.800% notes due 2025, which matured and were repaid in December 2025, and $500 million of 5.750% notes due 2027. In March 2021, we issued $500 million of 2.550% notes due 2031. We carry the notes at the principal amount, less unamortized discount and debt issuance costs, on our consolidated balance sheets. As the notes have fixed annual interest rates, we do not have economic interest rate exposure or financial statement risk associated with changes in interest rates. The fair value of the notes, however, may fluctuate when interest rates change. See note 5.

A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP San Diego, California February 11, 2026 95 95 95 Table of Contents Table of Contents" }, { "status": "UNCHANGED", "current_title": "Financial Instruments", "prior_title": "Financial Instruments", "current_body": "We are also subject to risks related to our financial instruments, including cash and cash equivalents, investments, and accounts receivable.

Our investment policy restricts the amount of credit exposure to any one issuer to 5% of the portfolio or 5% of the total issue size outstanding at the time of purchase and to any one industry sector, as defined by Clearwater Analytics (Industry Sector Report), to 30% of the portfolio at the time of purchase.

Suppliers We require customized products and components that currently are available from a limited number of sources. We source certain key products and components included in our products from single vendors. Historically, we have not experienced significant issues sourcing materials to build our products. Segments 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. Our CODM allocates resources and assesses the performance of segments using information about their revenue and net income (loss).

We are focusing on markets for analysis of genetic variation or biological function, namely sequencing, genotyping, and gene expression profiling. These markets are relatively new and emerging, and they may not develop as quickly as we anticipate, or reach what we expect to be their full potential. Other methods of analysis of genetic variation and biological function may emerge and displace the methods we are developing. In addition, a reduction or delay in research and development budgets and government funding may adversely affect our business. Many of our customers’, and a portion of our own, research and development and other activities have been funded, or may be funded in the future, by government grants, including from the U.S. National Institutes of Health, or NIH. Any reduction, delay, or elimination of government funding, or failure to comply with grant requirements, could materially and adversely affect our or our customers’ research programs, product development, manufacturing operations and financial condition. The introduction of next-generation sequencing technologies, including ours, has reduced the cost of sequencing by a factor of more than 10,000 and reduced the sequencing time per Gb by a factor of approximately 12,000 over the last 20 years. Consequently, demand for sequencing-related products and services has increased substantially as new applications are enabled and more sequencing is done in connection with existing applications. If, as we expect, the cost of sequencing continues to fall, we cannot be sure that the demand for related products and services will increase at least proportionately as new applications are enabled or more sequencing is done in connection with existing applications. In the future, if demand for our products and services due to lower sequencing costs is less than we expect, our business, financial condition, and results of operations will be adversely affected. Our products may be used to provide genetic information about humans, agricultural crops, other food sources, and other living organisms. The information obtained from our products could be used in a variety of applications, which may have underlying ethical, legal, and social concerns regarding privacy and the appropriate uses of the resulting information, including preimplantation genetic screening of embryos, prenatal genetic testing, genetic engineering or modification of agricultural products, or testing genetic predisposition for certain medical conditions, particularly for those that have no known cure. Our customers’ implementation of our products to provide their own products and services may raise such concerns and affect our own reputation. U.S. and international governmental authorities could, for social or other purposes, call for limits on or regulation of the use of genetic testing or prohibit testing for genetic predisposition to certain conditions, particularly for those that have no known cure. Similarly, such concerns may lead individuals to refuse to use genetics tests, even if permissible. These and other ethical, legal, and social concerns about genetic testing may limit market acceptance of our technology for certain applications or reduce the potential markets for our technology, either of which could have an adverse effect on our business, financial condition, or results of operations. 15 15 15" }, { "status": "UNCHANGED", "current_title": "Helix Contingent Value Right", "prior_title": "Helix Contingent Value Right", "current_body": "In conjunction with the deconsolidation of Helix Holdings I, LLC (Helix) in April 2019, we received a contingent value right with a 7-year term that entitled us to consideration dependent upon the outcome of Helix’s future financing and/or liquidity events.

Based on our analysis, we concluded GRAIL’s carrying value exceeded its fair value and recorded a goodwill impairment of $712 million, primarily due to the decrease in the Company’s consolidated market capitalization and a higher discount rate selected for the fair value calculation of GRAIL. There was no impairment for Core Illumina, as its fair value exceeded its carrying value. 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 GRAIL and Core Illumina 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%. An increase of 50 to 100 basis points to the discount rate would have resulted in additional impairment of $200 million to $350 million. 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. 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. In conjunction with our interim goodwill impairment test, we also evaluated GRAIL’s IPR&D intangible asset for potential impairment. We performed our 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, which represent a Level 3 measurement, included projected cash flows and a selected discount rate of 19.0%. Based on our analysis, the carrying value of GRAIL’s IPR&D intangible 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 IPR&D asset. We also performed a recoverability test for the definite-lived intangible assets assigned to GRAIL, which included developed technology and trade name, and to Core Illumina and noted no impairment. In Q4 2023, we concluded, among other events, that our formal announcement to divest GRAIL represented a triggering event that required an additional interim impairment test be performed. As a result of our analysis, no impairment was recorded for Core Illumina or GRAIL. The fair value of GRAIL exceeded its carrying value by approximately $950 million and the selected discount rate used in the analysis was 23.0%. An increase of 100 basis points to the discount rate would still have resulted in no impairment for GRAIL.

If indicators of impairment exist, we assess the recoverability of the asset or asset group by determining whether the carrying amount exceeds the undiscounted expected future cash flows. If the asset or asset group is not recoverable, we estimate the fair value of the assets and record an impairment loss if the carrying value exceeds the fair value. Factors that may indicate potential impairment include a significant decline in our stock price and market capitalization compared to net book value, significant changes in the ability of an asset to generate positive cash flows and the pattern of utilization of a particular asset. In order to estimate the fair values of identifiable intangible assets with finite lives and other long-lived assets, we estimate the present value of future cash flows from those assets. The key assumptions that we use in our cash flow model are the amount and timing of estimated future cash flows to be generated by the asset over an extended period of time and a rate of return that considers the relative risk of achieving the cash flows, the time value of money, and other factors that a willing market participant would consider. Management judgment is required to estimate the amount and timing of future cash flows and the relative risk of achieving those cash flows. We review our operating lease right-of-use (ROU) assets for impairment whenever events or changes in circumstances indicate the carrying value of the ROU asset may not be recoverable. The evaluation is performed at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. We consider a triggering event to reassess an ROU asset’s asset group to have occurred if we exit a portion of or the full facility or enter into a sublease. Factors that may indicate potential impairment include a significant decrease in the market price of an underlying leased asset group. If we conclude the carrying value of the assets or asset group will not be recovered, we estimate the fair value of the asset or asset group and record an impairment in an amount equal to the excess of the carrying value over fair value. We estimate the present value of future cash flows from the asset or asset group in order to determine fair value. There is uncertainty in the projected future cash flows used in our impairment review analysis, which requires the use of estimates and assumptions. 45 45 45 Assumptions and estimates about future values and remaining useful lives are complex and often subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our internal forecasts. For example, if our future operating results do not meet current forecasts or if we experience a sustained decline in our market capitalization that is determined to be indicative of a reduction in fair value of our reporting units, we may be required to record future impairment charges for purchased intangible assets with finite lives.
