Screening revenue grew over 250% to $52.9 million for the second quarter of 2026, from $14.8 million for the corresponding prior year period, driven primarily by an increase in Shield screening test volume, which grew to approximately 66,000 tests in the second quarter of 2026, from approximately 16,000 tests in the prior year period.

2026 Guidance

Guardant Health now expects full year 2026 revenue to be in the range of $1.34 to $1.36 billion, representing growth of 36% to 38% compared to full year 2025. This compares to the prior range of $1.30 to $1.32 billion, representing growth of 32% to 34%.

Within this revenue range:

• Oncology revenue is now expected to grow approximately 30% in 2026, compared to prior guidance of 28% to 29%. Oncology volume is now expected to grow to approximately 50% in 2026, compared to prior guidance of approximately 35%.
• 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 $218 to $230 million, driven by Shield volume of 270,000 to 285,000 tests. This compares to the prior guidance of $186 to $198 million revenue and 230,000 to 245,000 tests.

Guardant Health continues to expect full year 2026 non-GAAP gross margin to be in the range of 64% to 65%. Guardant Health now expects total non-GAAP operating expenses to be in the range of $1.08 to $1.10 billion, an increase compared to the prior range of $1.05 to $1.07 billion. Guardant Health now expects full-year free cash flow burn of $195 million to $205 million, compared with its previous outlook of $185 million to $195 million. The revised range reflects accelerated investment in laboratory capacity to support rapid Shield volume growth and represents an improvement from the $233 million of free cash flow burn reported for full-year 2025.

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 payments, contingent consideration, amortization of intangible assets, impairment of non-marketable equity securities, gain on extinguishment of convertible notes, and other non-recurring items.

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 payments; contingent consideration; and other non-recurring items. 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.
