Revenue of $1.06 billion for Q2 2025, down 3% from Q2 2024 on both a reported and constant currency basis
GAAP operating margin of 20.2% and non-GAAP operating margin of 23.8% for Q2 2025
GAAP diluted EPS of $1.49 and non-GAAP diluted EPS of $1.19 for Q2 2025
Cash provided by operations of $234 million and free cash flow of $204 million for Q2 2025
For fiscal year 2025, we now expect:

SAN DIEGO, July 31, 2025 /PRNewswire/ -- Illumina, Inc. (NASDAQ:ILMN) ("Illumina" or the "company") today announced its financial results for the second quarter of fiscal year 2025.

"The Illumina team again delivered results that exceeded our guidance, driven by the continued ramp in X consumables, as well as accelerating growth in clinical, our largest customer segment," said Jacob Thaysen, Chief Executive Officer. "In research, we are actively helping our customers navigate a constrained funding environment. Even in these challenging conditions, the team's focus on operational excellence helped drive margin expansion, enabling us to increase our expectations for the year."

(a)	See tables in "Results of Operations - Non-GAAP" section below for GAAP and non-GAAP reconciliations.
(b)	Revenue for Q2 2024 included intercompany revenue of $9 million prior to the spin-off of GRAIL.
(c)	Non-GAAP gross margin remained flat primarily due to higher freight and duties costs related to tariffs and an increase in field service costs, partially offset by lower strategic partnership revenue, that is lower margin, and a more favorable product mix. The decrease in GAAP gross margin was primarily due to a $23 million impairment of an acquired intangible asset.

Capital expenditures for free cash flow purposes were $30 million for Q2 2025. Cash flow provided by operations was $234 million, compared to $243 million in the prior year period. Free cash flow (cash flow provided by operations less capital expenditures) was $204 million for the quarter, compared to $213 million in the prior year period. Depreciation and amortization expense was $68 million for Q2 2025. At the close of the quarter, the company held $1.16 billion in cash, cash equivalents and short-term investments.

Share repurchases for Q2 2025 were $380 million and the company intends to repurchase incremental shares over the course of the year as part of our approximate $800 million authorization remaining at the end of the quarter.

Financial outlook and guidance

The company provides forward-looking guidance on a non-GAAP basis, including on a constant currency basis for revenue and revenue growth rates. The company is unable to provide a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP reported financial measures because it is unable to predict with reasonable certainty the impact of items such as acquisition-related expenses, fair value adjustments to contingent consideration, gains and losses from strategic investments, potential future asset impairments, restructuring activities, the ultimate outcome of pending litigation, and currency exchange rate fluctuations without unreasonable effort. These items are uncertain, inherently difficult to predict, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. For the same reasons, the company is unable to address the significance of the unavailable information, which could be material to future results.

Conference call information

The conference call will begin at 1:30 pm Pacific Time (4:30 pm Eastern Time) on Thursday, July 31, 2025. Interested parties may access the live webcast via the Investor Info section of Illumina's website or directly through the following link - https://illumina-earnings-call-q2-2025.open-exchange.net/. To ensure timely connection, please join at least ten minutes before the scheduled start of the call. A replay of the conference call will be posted on Illumina's website after the event and will be available for at least 30 days following.

Statement regarding use of non-GAAP financial measures

The company reports non-GAAP results for diluted earnings per share, net income, gross margin, operating expenses, including research and development expense, selling general and administrative expense, legal contingency and settlement, and goodwill and intangible impairment, operating income, operating margin, gross profit, other income (expense), tax provision, constant currency revenue and growth, and free cash flow (on a consolidated and, as applicable, segment basis) in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The company's financial measures under GAAP include substantial charges such as amortization of acquired intangible assets among others that are listed in the reconciliations of GAAP and non-GAAP financial measures included in this press release, as well as the effects of currency translation. Management has excluded the effects of these items in non-GAAP measures to assist investors in analyzing and assessing past and future operating performance. Non-GAAP net income, diluted earnings per share and operating margin are key components of the financial metrics utilized by the company's board of directors to measure, in part, management's performance and determine significant elements of management's compensation.

The company encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. Reconciliations between GAAP and non-GAAP results are presented in the tables of this release.

However, our calculation of free cash flow may not be comparable to similar measures used by other companies.
