Deals & partnerships

Nuvalent Collaboration to develop companion diagnostics

Initial focus on Guardant360 Tissue.

Quest Diagnostics Co-promotion and EMR connectivity for Shield

Collaboration went live in the field in Q1 FY26, contributing to strong Shield volume growth.

UnitedHealth Group Coverage for Shield for colorectal cancer screening

UnitedHealth Group is the largest commercial insurer in the U.S. and the first major insurer to cover Shield for average risk adults aged 45 and older.

Risks & headwinds

Increased CapEx for Shield lab capacity FY26

Full year FY26 free cash flow burn guidance raised by $10 million to $195 million-$205 million.

Mitigation:Accelerating investments to support anticipated growth and higher test volumes, greater processing efficiency, and improved turnaround times.

Delay in MolDX reimbursement for Reveal Beyond end of 2026 for some indications

Not quantified, but noted as 'taking a little bit longer than we would have liked'.

Mitigation:Submissions are progressing, with confidence in getting them over the finish line for breast and IO by end of 2026.

ASP realization for commercial payers for Guardant360 ADLT 12-24 months

Expected ADLT price of $8,455, but it will take 12 to 24 months for Medicare Advantage and commercial payers to align their pricing to the new Medicare rate, impacting realized ASP.

Mitigation:Ongoing conversations with payers; UnitedHealth coverage is a positive step that may influence other payers.

What to watch in Q3 FY26

Shield volume growth

Q3 FY26
Current 66,000 tests in Q2 FY26 (22,000 sequential step-up from Q1)
Target Sequential growth of 12,000 Q-over-Q (midpoint of guide)

Why it matters

Verifying if the strong Q2 momentum from Quest co-promotion, DTC, and field force expansion can be sustained, especially with UnitedHealth coverage becoming effective.

So we don't expect multiple new things all hitting at once in Q3. Having said that, we are very excited of what we can do in the second half, like we increased our guide by 40,000 samples, which translates at the midpoint, the guide that we put out there, like sequential growth of 12,000 Q-over-Q.

Q&A highlights

How will UnitedHealth Group coverage and ACS guidelines impact Shield's near-term volume and long-term ASP? What are the expectations for USPSTF's August meeting?

UnitedHealth coverage is expected to be a volume tailwind, helping to build commercial volume for younger patients. However, ASP realization will take time as negotiations and collection history are established. The company's expectations for USPSTF timing remain unchanged, despite some payers engaging in conversations earlier.

“This UHG win could actually give us some interesting benefits, like we are excited to see how the rest of the year would play out. It could be a tailwind for the volume. It would help us to strategically step-by-step build our commercial side of the volume, so not just 65 and above, but actually younger patients, make sure they get actually access to this breakthrough technology.”

Detailed narrative

Strategic Platform Vision and Market Opportunity

Guardant's Smart Platform is designed to address four major opportunities in precision medicine: therapy selection, recurrence monitoring, cancer screening, and multi-disease screening, collectively representing a nearly $400 billion potential market. This integrated platform leverages compounding technology, data, and clinical insights across the disease continuum, as evidenced by recent FDA approvals and guideline inclusions that advance this vision into clinical impact and durable growth.

Oncology Business Momentum and Product Acceleration

The Oncology segment delivered strong, broad-based growth, with revenue up 38% year-over-year and test volumes increasing 63%. Guardant360 Liquid saw over 30% volume growth, Guardant360 Tissue accelerated, and Reveal continued its rapid expansion with over 100% year-over-year volume growth for the third consecutive quarter.

Reveal's performance is driven by growing MRD adoption and its unique suitability for therapy monitoring in late-stage cancer, representing a multi-million test annual opportunity.

Shield Screening Breakthroughs and Market Expansion

The Shield screening business achieved significant milestones, including its inclusion in the American Cancer Society's colorectal cancer screening guidelines and a major coverage decision from UnitedHealth Group. These developments are expected to broaden patient access, with approximately 70 million lives (60% of the U.S. addressable market) now covered for Shield blood tests, driving strong demand and commercial execution.

Technological Advancements and Cost Efficiency

Guardant received FDA approval for Guardant360 Liquid CDx, enhancing its therapy selection portfolio with 100x more content and integrating genomic and epigenomic data. Additionally, FDA approval for a higher-throughput, lower-COGS Shield workflow is expected to reduce Shield's cost per test by approximately 15% by the end of 2026 from $410, with a long-term target of $200 per test by 2028, improving scalability and profitability.

Data and AI as Strategic Assets

The company highlighted its proprietary data asset, comprising over 1.3 million patient tests and 700,000 epigenetic profiles across more than 100 tumor types. This repository fuels the InfinityAI platform, enabling the discovery of novel biological signatures, development of clinically actionable Smart apps, and acceleration of drug discovery for biopharma partners, showcasing a strong positive response at ASCO.

Financial Performance and Outlook

Guardant raised its full-year 2026 revenue guidance to $1.34 billion to $1.36 billion, reflecting strong first-half results and increased confidence in Shield's trajectory. While accelerated investments in Screening lab capacity led to a revised free cash flow burn outlook of $195 million to $205 million, the company remains committed to achieving company-wide cash flow breakeven by the end of 2027, with the non-Screening business already adjusted EBITDA positive.
