Insights

Financial Analyst

Illumina's downgraded 2025 outlook signals significant headwinds, with revenue now expected to decline 1-3% amid tariff and China market pressures.

Illumina's Q1 results reveal a company navigating intensifying market challenges. Revenue of $1.04 billion declined 1% year-over-year, signaling stagnation in their core business. While the quarter delivered respectable GAAP operating margin of 15.8% (improved from 11.0% last year) and GAAP EPS of $0.82 (up from $0.44), the forward outlook has deteriorated substantially.

The most concerning development is Illumina's dramatic guidance revision. Management has pivoted from projecting low-single-digit growth to forecasting a 1-3% revenue decline for fiscal 2025. This reversal stems from multiple factors:

• Tariff impacts quantified at $85 million, reducing operating margins by 125 basis points and EPS by $0.25
• Greater China challenges (after reporting $72 million in Q1, only expecting $165-185 million for full year)
• Broader research funding environment constraints

Management has responded with a $100 million cost reduction program, but this only partially offsets the headwinds, resulting in reduced operating margin guidance of 21.5-22.0% (down from 23%) and EPS guidance of $4.20-4.30 (down from $4.50).

Despite these challenges, Illumina maintains financial stability with $1.24 billion in cash and investments. The $208 million Q1 free cash flow (though down from $251 million last year) and ongoing share repurchases ($200 million in Q1) demonstrate financial resilience. The company continues investing in innovation through strategic collaborations and new technology introductions, protecting long-term growth potential while addressing near-term obstacles.

The divergence between regions is telling – modest 0-2% growth expected outside China versus significant contraction within China – highlighting the geopolitical dimension of Illumina's challenges. This earnings report marks a clear inflection point, with external pressures overwhelming the company's operational improvements.

• Core Illumina revenue of $1.04 billion for Q1 2025, down 1% from Q1 2024 (flat on a constant currency basis)
• GAAP operating margin of 15.8% and non-GAAP operating margin of 20.4% for Q1 2025
• GAAP diluted EPS of $0.82 and non-GAAP diluted EPS of $0.97 for Q1 2025
• Cash provided by operations of $240 million and free cash flow of $208 million for Q1 2025
• For fiscal year 2025, we expect:
  • Core Illumina revenue to decline between (1%) and (3%) on a constant currency basis year over year, down from low single digit growth previously
    • Revenue outside of the Greater China region expected to grow between 0% and 2% in 2025 on a constant currency basis year over year and includes our estimate reflecting changes in the research funding environment as well as the projected benefit from pricing actions
    • Reported revenue from the Greater China region expected to be $165 - $185 million in 2025 (with $72 million in revenue recognized in Q1 2025)
  • $85 million in tariff related costs which after actions is an approximate 125 bps reduction in fiscal year 2025 operating margin and $0.25 of EPS
  • Non-GAAP operating margin of approximately 21.5% - 22.0%, down from approximately 23% previously; and non-GAAP diluted EPS in the range of $4.20 - $4.30, a reduction from our March guidance of approximately $4.50, primarily due to the net impact of tariffs

SAN DIEGO, May 8, 2025 /PRNewswire/ -- Illumina, Inc. (Nasdaq: ILMN) ("Illumina" or the "company") today announced its financial results for the first quarter of fiscal year 2025.

"I'm proud that the Illumina team delivered strong Q1 revenue and EPS, a good start to the year in an increasingly dynamic business environment," said Jacob Thaysen, Chief Executive Officer. "Our outlook for the year has weakened due to shifting policy and geopolitical developments and we have taken swift incremental actions to protect our earnings. Our strategic focus remains on customer collaboration, driving differentiated innovations, and delivering on our long-term financial targets of growth and profitability."

Capital expenditures for free cash flow purposes were $32 million for Q1 2025. Cash flow provided by operations was $240 million, compared to $284 million in the prior year period. Free cash flow (cash flow provided by operations less capital expenditures) was $208 million for the quarter, compared to $251 million in the prior year period.

Financial outlook and guidance
For fiscal year 2025, we expect:

• • Core Illumina revenue to decline between (1%) and (3%) on a constant currency basis year over year, down from low single digit growth previously
    • Revenue outside of the Greater China region expected to grow between 0% and 2% in 2025 on a constant currency basis year over year and includes our estimate reflecting changes in the research funding environment as well as the projected benefit from pricing actions
    • Reported revenue from the Greater China region expected to be $165 - $185 million in 2025 (with $72 million in revenue recognized in Q1 2025)
  • $85 million in tariff related costs which after actions is an approximate 125 bps reduction in fiscal year 2025 operating margin and $0.25 of EPS
  • Non-GAAP operating margin of approximately 21.5% - 22.0%, down from approximately 23% previously; and non-GAAP diluted EPS in the range of $4.20 - $4.30, a reduction from our March guidance of approximately $4.50, primarily due to the net impact of tariffs

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, May 8, 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-q1-2025.open-exchange.net/.

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.

(a)

Free cash flow, which is a non-GAAP financial measure, is calculated as net cash provided by operating activities reduced by purchases of property and equipment. Free cash flow is useful to management as it is one of the metrics used to evaluate our performance and to compare us with other companies in our industry. However, our calculation of free cash flow may not be comparable to similar measures used by other companies.
