What dominates the section
- China’s List of Unreliable Entities designation threatens Illumina’s Chinese revenue and operations.
- GRAIL’s separation leaves continuing regulatory, tax, and contingent-value-right obligations.
- Growth depends on sequencing adoption, new products, diagnostic reimbursement, and compliance with changing FDA rules for laboratory-developed tests.
The risks most specific to Illumina
- Risks Relating to Our Sales of Products and Services, Marketing and Research and Development
China’s Ministry of Commerce has added Illumina to its List of Unreliable Entities, which could result in fines or restrictions on our ability to do business in China and could have a material adverse effect on our revenue and results of operations
China’s Ministry of Commerce placed Illumina on its List of Unreliable Entities, potentially restricting business or imposing fines in China.
- Risks Related to Acquisitions, Including the Acquisition of GRAIL
As previously disclosed, the Acquisition was subject to various legal challenges, including by the FTC and European Commission. As a result, we have been a party to a number of regulatory and administrative proceedings regarding the Acquisition
Regulatory and legal proceedings surrounding the GRAIL Acquisition continue following GRAIL’s June 2024 separation.
- Risks Related to Acquisitions, Including the Acquisition of GRAIL
Following the Spin-Off, we remain the obligor on the contingent value rights (the CVRs) we issued in connection with the GRAIL Acquisition
Illumina remains responsible for GRAIL Acquisition contingent value rights, but estimating liabilities is harder without owning GRAIL.
- Risks Related to Acquisitions, Including the Acquisition of GRAIL
The Spin-Off could result in substantial tax liability
The GRAIL Spin-Off could create substantial tax liability if it fails to qualify for intended U.S. tax treatment.
- Risks Relating to Government Regulation
Certain of our in vitro diagnostic products, or IVDs, are currently available through laboratories that are certified under the Clinical Laboratory Improvements Amendments (CLIA) of 1988. These IVD products are commonly called “laboratory developed tests,” or LDTs
New FDA rules may subject Illumina-supported laboratory-developed tests to medical-device requirements, increasing compliance burdens and potentially limiting availability.
- Risks Relating to Our Sales of Products and Services, Marketing and Research and Development
As we develop, market, or sell diagnostic tests, we may encounter delays in receipt, or limits in the amount, of reimbursement approvals and public health funding, which will impact our ability to grow revenues in the healthcare market
Diagnostic growth depends on Medicare, Medicaid, managed-care, and foreign payors approving and substantially reimbursing tests such as prenatal tests.
- Risks Relating to Supply Chain, Manufacturing, and Quality
An interruption in our ability to manufacture our products or an inability to obtain key components or raw materials due to a catastrophic disaster, infectious disease, or infrastructure failure could adversely affect our business
Manufacturing is concentrated in facilities in California, Wisconsin, the United Kingdom, and Singapore, exposing supply to disasters and infrastructure failures.
- Risks Relating to Our Sales of Products and Services, Marketing and Research and Development
Our success depends upon the continued emergence and growth of markets for analysis of genetic variation, and continued substantial increases in the use of sequencing as the cost of sequencing declines
Illumina’s technologies require expanding markets for genetic-variation analysis and continued sequencing adoption as sequencing costs decline.
- Risks Relating to Our Sales of Products and Services, Marketing and Research and Development
If we do not successfully manage the development, manufacturing, and launch of new products or services, including product transitions, our financial results could be adversely affected
Failed product launches or transitions could leave Illumina unable to forecast customer purchasing and recover development, manufacturing, or launch costs.
All 30 risk factors
Headings as the filing states them, in filing order.

About this page
Item 1A of the 10-K on EDGAR was split into its risk factors and, where the company's previous 10-K is on file, each heading was matched to last year's and the text compared word for word. The headings are the filing's own. The one-line readings and the overview were written by a language model from the text of the new, dropped, and rewritten risks; they refer to risks by position and cannot misquote a heading.
