Third quarter 2026 revenue growth of 36% driven by strong performance in Oncology and Screening

Raises 2026 revenue guidance to $1.36 to $1.37 billion, representing growth of 38% to 40%

PALO ALTO, Calif.--(BUSINESS WIRE)-- Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today reported financial results for the quarter ended September 30, 2026.

Third Quarter 2026 Financial Highlights

For the three-month period ended September 30, 2026, as compared to the same period of 2025:

• Reported total revenue of $361.0 million, an increase of 36%, driven by:
  • Oncology revenue of $231.3 million, an increase of 25%, and 117,000 oncology tests, an increase of 58%
  • Biopharma & Data revenue of $59.0 million, an increase of 8%
  • Screening revenue of $67.6 million, an increase of 180%, and 83,000 Shield tests, an increase of 246%
• Generated non-GAAP gross margin of 67%, compared to 66% for the third quarter of 2025

Recent Operating Highlights

• Received U.S. Food and Drug Administration (FDA) approval and CE-marking in Europe for Guardant360 CDx as a companion diagnostic for AstraZeneca’s ETCAMAH (camizestrant), the first FDA approval of a liquid biopsy companion diagnostic for longitudinal testing in breast cancer
• Received FDA approval for Guardant360 CDx as a companion diagnostic for INLURIYO (imlunestrant) in combination with VERZENIO (abemaciclib) for eligible patients with ESR1-mutated advanced or metastatic breast cancer
• Submitted a premarket approval (PMA) application to the FDA for Guardant360 Tissue
• Launched Guardant Reveal Ultra with biopharma partners and remain on track for clinical launch in 2026
• Expanded commercial coverage for Shield to more than 80% of eligible lives, with key additions including UnitedHealth Group, Carelon Healthcare Services, and EviCore
• Successfully deployed the new FDA-approved lower COGS, higher-throughput Shield workflow

“Revenue grew 36% year over year as we continued to execute across Oncology, Screening, and Biopharma,” said Helmy Eltoukhy, co-founder and co-CEO. “Oncology volume grew 58% with broad contributions across our portfolio. The FDA approval of Guardant360 CDx for longitudinal ESR1 testing is a major advance for breast cancer patients, ushering in a new paradigm of cancer treatment. It reinforces the role of Guardant360 in enabling earlier therapy decisions and strengthens our leadership across the cancer care continuum.”

“Shield continued to build momentum in the third quarter, with volume more than tripling year over year to 83,000 tests,” said AmirAli Talasaz, co-founder and co-CEO. “Commercial coverage continues to expand, with recent policy updates extending Shield coverage to approximately 100 million lives. With our lower COGS, higher-throughput workflow now fully implemented, we have a strong operational foundation to meet future Shield demand. Together, these advances expand access to Shield and move us closer to making blood-based cancer screening a routine part of preventive care.”

Screening revenue grew 180% to $67.6 million for the third quarter of 2026, from $24.1 million for the corresponding prior year period, driven primarily by an increase in Shield test volume, which grew to 83,000 tests in the third quarter of 2026, from 24,000 tests in the prior year period.

2026 Guidance

Guardant Health now expects full year 2026 revenue to be in the range of $1.36 to $1.37 billion, representing growth of 38% to 40% compared to full year 2025. This compares to the prior range of $1.34 to $1.36 billion, representing growth of 36% to 38%.

Within this revenue range:

• Oncology revenue is expected to grow approximately 30% and Oncology volume is now expected to grow over 50%.
• Biopharma & Data revenue growth is expected to be in the low double-digit range.
• Screening revenue is now expected to be in the range of $233 to $238 million, driven by Shield volume of 285,000 to 290,000 tests. This compares to the prior guidance of $218 to $230 million revenue and 270,000 to 285,000 tests.

Guardant Health now expects full year 2026 non-GAAP gross margin to be 65%, compared to prior guidance of 64% to 65%. The company expects total non-GAAP operating expenses to be in the range of $1.105 to $1.125 billion, an increase compared to the prior range of $1.080 to $1.100 billion. Guardant Health now expects full-year free cash flow burn of $205 million to $220 million, compared to the previous outlook of $195 million to $205 million.

Webcast Information

Guardant Health will host a conference call to discuss the third quarter 2026 financial results after market close on Thursday, November 5, 2026 at 1:30 pm Pacific Time / 4:30 pm Eastern Time. A webcast of the conference call can be accessed at http://investors.guardanthealth.com. The webcast will be archived and available for replay for at least 90 days after the event.

Non-GAAP Measures

Guardant Health has presented in this release certain financial information in accordance with U.S. Generally Accepted Accounting Principles (GAAP) and also on a non-GAAP basis, including non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP research and development expense, non-GAAP sales and marketing expense, non-GAAP general and administrative expense, non-GAAP loss from operations, non-GAAP net loss, non-GAAP net loss per share, basic and diluted, adjusted EBITDA, and free cash flow.

We define our non-GAAP measures as the applicable GAAP measure adjusted for the impacts of stock-based compensation and related employer payroll tax expense, amortization of intangible assets, impairment of non-marketable equity securities, gain on extinguishment of convertible notes, and other items, including contingent consideration and non-recurring legal expenses.

Adjusted EBITDA is defined as net loss adjusted for interest income; interest expense; other income (expense), net; provision for income taxes; depreciation and amortization expense; stock-based compensation expense and related employer payroll tax expense; and other items, including contingent consideration and non-recurring legal expenses. Free cash flow is defined as net cash used in operating activities in the period less purchases of property and equipment in the period.

We believe that the exclusion of certain income and expenses in calculating these non-GAAP financial measures can provide a useful measure for investors when comparing our period-to-period core operating results, and when comparing those same results to that published by our peers. We exclude certain items because we believe that these income and expenses do not reflect expected future operating performance. Additionally, certain items are inconsistent in amounts and frequency, making it difficult to perform a meaningful evaluation of our current or past operating performance. We use these non-GAAP financial measures to evaluate ongoing operations, for internal planning and forecasting purposes, and to manage our business.

These non-GAAP financial measures are not intended to be considered in isolation from, as substitute for, or as superior to, the corresponding financial measures prepared in accordance with GAAP. There are limitations inherent in non-GAAP financial measures because they exclude charges and credits that are required to be included in a GAAP presentation, and do not present the full measure of our recorded costs against its revenue. In addition, our definition of the non-GAAP financial measures may differ from non-GAAP measures used by other companies.

Key Terms

companion diagnostic medical

A companion diagnostic is a medical test designed to identify which patients are likely to benefit from a specific drug or medical treatment, much like a key that shows whether a particular lock will open. For investors, these tests matter because they can increase a drug’s chances of approval and market uptake, create a separate revenue stream, and reduce commercial risk by matching treatments to the patients most likely to respond.

liquid biopsy medical

A liquid biopsy is a laboratory test that looks for tiny pieces of tumor or disease-related material — such as DNA, proteins, or cells — circulating in blood or other body fluids, allowing detection and monitoring without a surgical tissue sample. For investors, it matters because these tests can speed diagnosis, guide treatment choices, enable easier repeat testing, and create recurring revenue streams if adopted widely, affecting a medical company's growth and regulatory risk profile.

premarket approval (pma) regulatory

Premarket Approval (PMA) is the strict regulatory review process used by the U.S. authority for high-risk medical devices to prove they are safe and effective before they can be sold. For investors, a granted PMA is like receiving a key to a locked market: it can open exclusive sales opportunities, reduce near-term competition, and justify higher valuations, while also signaling that the company has cleared a costly, time-consuming hurdle.

non-gaap financial

Non-GAAP refers to financial measures that companies use to show their earnings or performance without including certain expenses or income that are often added back to give a different picture. It matters because it can make a company's results look better or more favorable, but it may also hide important costs, so investors need to look at both GAAP (official rules) and non-GAAP numbers to get a full understanding.
