Summary
Summary of the 8-K filed January 13, 2026. Cited figures are marked; the original filing is the authoritative source.
Illumina, Inc. (Nasdaq: ILMN) filed this Form 8-K on January 13, 2026 under Item 2.02 (Results of Operations and Financial Condition) to furnish a press release with unaudited preliminary financial results for the fourth quarter and fiscal year ended December 28, 2025.
The results were issued ahead of a presentation at the 44th Annual J.P. Morgan Healthcare Conference. The company states that these results are preliminary, remain subject to the completion of accounting and annual audit procedures, and may be adjusted.
Full fourth quarter and fiscal 2025 results are expected after the market close on February 5, 2026. For the fourth quarter of 2025, the company reported preliminary revenue of approximately $1.155 billiona, up 5% from the prior-year quarter (up 4% on a constant currency basis), and ex-China revenue of approximately $1.100 billion, up 7%. Preliminary GAAP diluted EPS was $2.14 to $2.17, and non-GAAP diluted EPS was $1.27 to $1.30.
A large strategic investment gain, net of $(1.24) per share, is a major reconciling item between GAAP and non-GAAP EPS for the quarter. For fiscal year 2025, preliminary revenue was approximately $4.34 billionb, flat compared with 2024 on both reported and constant currency bases. Ex-China revenue was approximately $4.10 billion, up 2%.
Preliminary GAAP diluted EPS was $5.42 to $5.45c, and non-GAAP diluted EPS was $4.76 to $4.79. The filing also references the pending acquisition of SomaLogic from Standard BioTools Inc., which remains subject to regulatory approvals, and the company's inclusion on China's "unreliable entities list."

Are these fourth-quarter and fiscal 2025 results final?
No. The filing states the figures are unaudited and preliminary, subject to completion of accounting and annual audit procedures, and therefore subject to adjustment. Full results are scheduled for release after the market close on February 5, 2026.

Why do GAAP and non-GAAP EPS differ so much in the fourth quarter?
The reconciliation shows a strategic investment gain, net, of $(1.24) per share in Q4 2025, which is excluded from non-GAAP results.

What is the status of the pending SomaLogic acquisition?
The filing describes the proposed acquisition of SomaLogic, Inc. and certain other assets from Standard BioTools Inc. as pending.

Ex-China revenue was approximately $1.100 billion in Q4 2025, up 7%, and approximately $4.10 billion for fiscal 2025, up 2%. The filing also lists uncertainty regarding the impact of Illumina's inclusion on the 'unreliable entities list' by Chinese regulatory authorities as a risk factor.
