SAN DIEGO, Nov. 4, 2024 /PRNewswire/ -- Illumina, Inc. (NASDAQ:ILMN) ("Illumina" or the "company") today announced its financial results for the third quarter of fiscal year 2024. The financial results for YTD 2024 and Q3 2023 and YTD 2023 include the financial results for GRAIL which was spun off on June 24, 2024.

"During the third quarter, the Illumina team delivered strong operating results, and revenue met our expectations," said Jacob Thaysen, Chief Executive Officer. "We are making good strides towards Illumina's strategic goals, both in launching breakthrough innovation and in helping our customers accelerate their adoption of the NovaSeq™ X."

"The near-term macroeconomic environment remains constrained, and we are slightly lowering our 2024 revenue guidance," Thaysen continued. "The underlying demand for Illumina's products and applications remains strong and we are demonstrating significant progress in driving margin and earnings expansion."

Financial outlook and guidance

For fiscal year 2024, the company is lowering its guidance for Core Illumina revenue to decline ~3% (down ~3% in constant currency) compared to fiscal year 2023. For the fourth quarter of 2024, the company expects Core Illumina revenue of ~$1.07 billion. The company is raising its guidance for Core Illumina non-GAAP operating margin to a range of 21% to 21.5%, and for Core Illumina non-GAAP diluted EPS to a range of $4.05 to $4.15 for fiscal year 2024.

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 p.m. Pacific Time (4:30 p.m. Eastern Time) on Monday, November 4, 2024. Interested parties may access the live teleconference through the Investor Info section of Illumina's website at investor.illumina.com. Alternatively, individuals can access the call by dialing 877.400.0505 or +1.323.701.0225 outside North America, both using conference ID 2966739. To ensure timely connection, please dial in 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.

Use of forward-looking statements

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

All amounts in tables are rounded to the nearest millions, except as otherwise noted. As a result, certain amounts may not recalculate using the rounded amounts provided. 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 (expense) income, 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, as well as the acquisition of Fluent Biosciences which was completed in Q3 2024. Amounts in other (expense) income, net for Q3 2023 and YTD 2023 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 the hedge for the EC fine.
(e)	Amounts consist primarily of mark-to-market adjustments and impairments from strategic investments. Amount for YTD 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 for Q3 2024 consist primarily of employee severance costs. Amounts for YTD 2024 also consist of lease and other asset impairments. Amounts for Q3 2023 consist primarily of lease and other asset impairments and amounts for YTD 2023 consist primarily of employee severance costs and lease and other asset impairments.
(h)	Amounts for Q3 2024 and YTD 2024 primarily consist of the reversal of the accrued EC fine, including accrued interest. Amount for YTD 2023 primarily consists of an adjustment recorded to our accrual for the EC fine.
(i)	Amount for YTD 2024 consists of goodwill and IPR&D intangible asset impairments related to GRAIL in Q2 2024. Amount for YTD 2024 also consists of an IPR&D intangible asset impairment related to Core Illumina in Q1 2024. Amounts for Q3 2023 and YTD 2023 consist of goodwill and IPR&D intangible asset impairments related to GRAIL.
