SAN DIEGO, Aug. 9, 2023 /PRNewswire/ -- Illumina, Inc. (NASDAQ:ILMN) ("Illumina" or the "company") today announced its financial results for the second quarter of fiscal year 2023, which include the consolidated financial results for GRAIL.

"Illumina's second quarter consolidated revenue grew 8% sequentially from the first quarter, and we saw higher-than-anticipated NovaSeq X shipments," said Charles Dadswell, Interim Chief Executive Officer. "Despite additional placements, we expect our second half revenue to be negatively impacted by customers remaining more cautious in their purchasing, a more protracted recovery in China, and a larger-than-expected temporary decline in high throughput consumables as customers transition to the NovaSeq X. In response, we are increasing customer support for the NovaSeq X and continue to manage our expense base in a disciplined way."

Capital expenditures for free cash flow purposes were $47 million for Q2 2023. Cash flow provided by operations was $105 million, compared to $125 million in the prior year period. Free cash flow (cash flow provided by operations less capital expenditures) was $58 million for the quarter, compared to $54 million in the prior year period. Depreciation and amortization expenses were $108 million for Q2 2023. At the close of the quarter, the company held $1,559 million in cash, cash equivalents and short-term investments, compared to $2,037 million as of January 1, 2023. On July 12, 2023, the European Commission imposed a €432 million fine due to the completion of the GRAIL acquisition during the pendency of the European Commission's review. While expected and accrued for over the last year, Illumina believes that the fine is unlawful, inappropriate, and disproportionate, and is appealing the decision. Illumina plans to issue a guarantee and defer the payment of the fine pending the outcome of the appeal of the EU General Court's ruling that the European Commission has jurisdiction to review the GRAIL acquisition.

Second quarter segment results

Illumina has two reportable segments, Core Illumina and GRAIL.

Core Illumina

(a) See Table 3 included in the "Results of Operations - Non-GAAP" section below for reconciliations of these GAAP and non-GAAP financial measures.

(b) Core Illumina revenue for Q2 2023 was flat as compared to Q2 2022, and up 2% on a constant currency basis. Amounts for Q2 2023 and Q2 2022 included intercompany revenue of $5 million and $6 million, respectively, which is eliminated in consolidation.

(c) The year-over-year decrease in gross margin was primarily driven by lower instrument margins due to the NovaSeq X launch, which is typical with a new platform introduction, less fixed cost leverage on lower manufacturing volumes, and higher field services and installation costs.

As previously stated, Illumina is committed to moving as quickly as possible through the legal and regulatory processes associated with its acquisition of GRAIL. If the company loses either its appeal in the US Court of Appeals for the Fifth Circuit or its appeal in the European Court of Justice (ECJ), Illumina expects to move quickly to divest GRAIL in a manner that serves the best interests of its shareholders. Should the company win both appeals, Illumina would undertake a detailed review of the GRAIL business, as it would no longer be subject to the hold separate, and determine the optimal outcome for the asset, also in the best interests of Illumina's shareholders. Success in the ECJ appeal removes any fines; prevailing in the appeals increases the options to deliver value to shareholders. The legal and regulatory processes are finite; Illumina expects decisions from the US Court of Appeals for the Fifth Circuit in late 2023 and from the ECJ in late 2023 or early 2024.

Financial outlook and guidance

The non-GAAP financial guidance discussed below reflects certain pro forma adjustments to assist in analyzing and assessing our core operational performance, including the company's Core Illumina and GRAIL segments. Please see our Reconciliation of Consolidated Non-GAAP Financial Guidance included in this release for a reconciliation of these GAAP and non-GAAP financial measures.

For fiscal year 2023, the company now expects consolidated revenue growth of approximately 1% compared to fiscal year 2022. The company now expects Core Illumina revenue to be approximately flat compared to fiscal year 2022. GRAIL revenue is still expected to be in the range of $90 million to $110 million.

The company now expects GAAP diluted loss per share of $(2.08) to $(1.93) and non-GAAP diluted earnings per share of $0.75 to $0.90. The GAAP and non-GAAP diluted (loss) earnings per share guidance ranges continue to assume that the existing R&D capitalization requirements are not repealed in fiscal year 2023 and, as a result, reflect a tax expense impact of approximately $75 million.

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, and from time to time, as applicable, legal contingencies and settlement, and goodwill impairment, operating income (loss), operating margin, gross profit (loss), other income (expense), tax provision, constant currency revenue growth, and free cash flow (on a consolidated and, as applicable, segment basis for our Core Illumina and GRAIL segments) 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 itemized reconciliations between 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, including in the non-GAAP measures related to our Core Illumina and GRAIL segments. Additionally, non-GAAP net income and diluted earnings per share 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.

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.

(a) Non-GAAP net income and diluted earnings per share exclude the effects of the pro forma adjustments as detailed above. Non-GAAP net income and diluted earnings per share 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. Management has excluded the effects of these items in these measures to assist investors in analyzing and assessing our past and future operating performance.

(b) Refer to the Itemized Reconciliations between GAAP and Non-GAAP Results of Operations for the components of these amounts.

(c) Amounts represent the impact of GRAIL pre-acquisition net operating losses on GILTI and the utilization of U.S. foreign tax credits.

(d) Incremental non-GAAP tax expense reflects the tax impact of the non-GAAP adjustments listed.

(e) Amounts represent the difference between book and tax accounting related to stock-based compensation cost.

(f) In loss periods, GAAP basic loss per share and diluted loss per share are identical since the effect of potentially dilutive shares is anti-dilutive and therefore excluded. For non-GAAP diluted earnings per share, the impact of potentially dilutive shares from our convertible senior notes and equity awards is included and is calculated based on the sum of weighted-average common shares and potentially dilutive shares outstanding during Q2 2022 and YTD 2022.

(g) Amount represents interest expense on the 2023 Convertible Senior Notes, net of any income tax effects, which is added back to the numerator used to calculate non-GAAP diluted earnings per share, for purposes of the if-converted method, as it would have a dilutive effect on the calculation of non-GAAP diluted earnings per share.

More information on potential factors that could affect our financial results is included from time to time in the public reports filed with the Securities and Exchange Commission, including Form 10-K for the fiscal year ended January 1, 2023 filed with the SEC on February 17, 2023 and Form 10-Q for the fiscal quarter ended April 2, 2023. We assume no obligation to update any forward-looking statements or information.
