ILLUMINA, INC.

As of December 28, 2025, we had $1,418 million in cash and cash equivalents, of which $444 million was held by foreign subsidiaries. Cash and cash equivalents increased by $291 million from the prior year due to factors described in the “Cash Flow Summary” below. Our primary source of liquidity, other than holdings of cash, cash equivalents, and investments, has been cash flows from operations and, from time to time, issuances of debt. In 2025, we received net proceeds from the issuance of our 2030 Term Notes of$495 million, and repaid $500 million for our 2025 Term Notes. 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 2025, we received proceeds from net sales of our strategic investments of $103 million. As of December 28, 2025, we had $215 million remaining in short-term investments, comprised of marketable equity securities. Subsequent to December 28, 2025 and through February 11, 2026, we received additional proceeds of approximately $104 million from subsequent sales of our short-term strategic investments.

In November 2025, we issued $500 million aggregate principal amount of 2030 Term Notes. We received net proceeds of $495 million. The 2030 Term Notes, which mature on December 12, 2030, accrue interest at a rate of 4.750% per annum, payable semi-annually on June 12 and December 12 of each year, beginning on June 12, 2026. We may redeem for cash all or any portion of the 2030 Term Notes, at our option, at any time prior to maturity.

In September 2024, we issued $500 million aggregate principal amount of 2026 Term Notes, which mature on September 9, 2026 and accrue interest at a rate of 4.650% per annum, payable semi-annually in March and September of each year. 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 matured and were repaid in cash on December 12, 2025. The 2027 Term Notes mature on December 13, 2027 and accrue interest at a rate of 5.750% per annum, 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 2026, 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 28, 2025, there were no outstanding borrowings.

On June 22, 2025, we entered into a Stock Purchase Agreement (the Purchase Agreement) with Standard BioTools to acquire SomaLogic and other specified assets for $350 million in cash, subject to customary adjustments. The Purchase Agreement further provides for, in connection with the revenues generated from certain products and services, (i) royalty streams and (ii) up to $75 million in potential milestone payments to Standard BioTools. The transaction was completed on January 30, 2026. See note 13. Subsequent Events for further details.

As of December 28, 2025, the fair value of our contingent consideration liability related to GRAIL was $54 million, of which $52 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 2025, we paid $1.3 million in aggregate Covered Revenue Payments related to aggregate Covered Revenues for the period Q4 2024 through Q3 2025 of $142 million.

In August 2024, our Board of Directors authorized a share repurchase program, which canceled and superseded 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 $643 million of our outstanding common stock remained available as of December 28, 2025. Subsequent to December 28, 2025 and through February 11, 2026, we repurchased an additional approximate 264,000 shares of our common stock for approximately $32 million. We intend to continue to repurchase incremental shares over the course of 2026.

We had $3 million, $33 million, and $25 million, respectively, remaining in capital commitments to three investment funds as of December 28, 2025 that are callable through April 2026, July 2029, and December 2034, respectively.

Our other short-term and long-term material cash requirements, from known contractual obligations as of December 28, 2025, 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 our current cash, cash equivalents, and short-term investments, together with cash provided by operations 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, including the SomaLogic acquisition that was completed on January 30, 2026 and funded from cash on hand. See note 13. Subsequent Events for further details. 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.
