What dominates the section
- Guardant remains deeply unprofitable, with a $436.4 million 2024 net loss and $2.6 billion accumulated deficit.
- Tests generated 93% of 2024 revenue, making adoption, reimbursement and payer concentration central risks.
- Regulatory exposure is substantial, especially FDA oversight of LDTs, EU IVDR requirements and clinical-laboratory licensing.
- Operations depend on a Redwood City laboratory, third-party phlebotomy, couriers and limited suppliers including Illumina.
The risks most specific to Guardant Health
- Risks related to our business and strategy
Our current revenue is primarily generated from sales of our tests and we are highly dependent on them for our success
Tests generated 93% of 2024 revenue, so reduced adoption or use of Guardant’s tests could undermine growth and profitability.
- Risks related to our business and strategy
If we cannot maintain our current relationships, or enter into new relationships, with biopharmaceutical companies, our revenue prospects could be reduced
Losing biopharmaceutical relationships could reduce revenue from clinical studies, companion diagnostics, retrospective testing and data services.
- Risks related to our business and strategy
Our payer concentration may materially adversely affect our financial condition and results of operations
A small number of mostly non-contracted commercial payers provide substantial revenue, creating exposure to reimbursement reductions or discontinued payments.
- Risks related to our business and strategy
We rely on a limited number of suppliers or, in some cases, sole suppliers, for some of our laboratory instruments and materials and may not be able to find replacements or promptly transition to alternative suppliers
Limited or sole suppliers, including Illumina for sequencers and reagents, could cause shortages or delays in laboratory operations.
- Risks related to our business and strategy
If our existing laboratory facility becomes damaged or inoperable or we are required to vacate our existing facility, our ability to perform our tests and pursue our research and development efforts may be jeopardized
Damage or loss of Guardant’s single Redwood City laboratory could interrupt most testing revenue and research and development.
- Risks related to our business and strategy
We are dependent on third parties for the collection of blood samples for our tests
Third-party phlebotomy providers may stop collecting samples or favor competitors, disrupting access to specimens for Guardant tests.
- Risks related to our highly regulated industry
Certain of our tests are currently marketed as LDTs, and future changes in FDA enforcement discretion for LDTs could subject our operations to much more significant regulatory requirements
FDA changes to enforcement discretion could impose substantially greater requirements on Guardant360, Guardant Reveal, Shield and other LDTs.
- Risks related to our highly regulated industry
In order to sell our products in member states of the EU, our products must comply with the essential requirements of the new In Vitro Diagnostic Regulation (IVDR) 2017/746 issued and implemented by the European Union (EU) in May 2022
EU IVDR requires notified-body involvement for high-complexity tests including Guardant360, Guardant360 Response, Guardant360 Tissue Next and Guardant Reveal.
- Risks related to our highly regulated industry
Failure to comply with federal, state and foreign laboratory licensing requirements and the applicable requirements of the FDA or any other regulatory authority, could cause us to lose the ability to perform our tests, experience disruptions to our business, or become subject to administrative or judicial sanctions
Failure to meet CLIA, state licensing or other laboratory requirements could suspend testing, disrupt operations or trigger sanctions.

- 35licensure requirements in new jurisdictions may be expensive, time-consuming and subject us to significant and unanticipated delays

- 55Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell their shares, could result in a decrease in the market price of our common stock

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.
