Financial outlook and guidance

Fiscal year 2025 guidance does not attempt to reflect any impact from the recent China Ministry of Commerce announcement and assumes a continuation of the current macroeconomic and political environments. For fiscal year 2025, the company continues to expect Core Illumina constant currency revenue growth in the low single digits (reported revenue in the range of approximately $4.28 billion to $4.4 billion) and non-GAAP operating margin of approximately 23%. The company expects non-GAAP diluted EPS in the range of $4.50 to $4.65.

The company provides forward-looking guidance on a non-GAAP basis. 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, gains and losses from strategic investments, fair value adjustments to contingent consideration, potential future asset impairments, restructuring activities, and the ultimate outcome of pending litigation 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, February 6, 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-q4-2024.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 contingencies and settlement, and goodwill and intangible impairment, operating income, operating margin, gross profit, other income (expense), tax provision, constant currency revenue 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.

Amounts in tables are rounded to the nearest millions. As a result, certain amounts may not recalculate.
Percentages of revenue are calculated based on the revenue of the respective segment.

(a)	Non-GAAP gross profit, included within non-GAAP operating profit (loss), is a key measure of the effectiveness and efficiency of manufacturing processes, product mix and the average selling prices of our products and services. Non-GAAP operating profit (loss) and non-GAAP other income (expense), net exclude the effects of the pro forma adjustments as detailed above. Non-GAAP operating margin is a key component 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. Management has excluded the effects of these items in these measures to assist investors in analyzing and assessing past and future operating performance.
(b)	Reconciling amounts are recorded in cost of revenue.
(c)	Amounts consist primarily of fair value adjustments for our contingent consideration liability related to GRAIL.
(d)	Amounts consist primarily of legal and other expenses related to the acquisition and divestiture of GRAIL. Amounts in other income (expense), net relate to unrealized gains/losses for foreign currency balance sheet remeasurement of the EC fine liability, which was reversed in Q3 2024, and mark-to-market gains/losses on hedge for the EC fine.
(e)	Amounts consist primarily of mark-to-market adjustments and impairments from strategic investments. Amount for FY 2024 primarily relates to impairment recorded on our retained investment in GRAIL post spin-off.
(f)	Amounts consist of fair value adjustments related to our Helix contingent value right, which was settled in Q3 2024.
(g)	Amounts consist primarily of lease and other asset impairments and employees severance costs.
(h)	Amount for FY 2024 primarily consists of the reversal of the accrued EC fine, including accrued interest. Amount for FY 2023 primarily consists of an adjustment recorded to our accrual for the EC fine.
(i)	Amounts for FY 2024 and FY 2023 consist of goodwill and IPR&D intangible asset impairments related to GRAIL and IPR&D intangible asset impairments related to Core Illumina.
