First Quarter 2026 Financial Results

Oncology revenue grew 36% to $205.0 million for the first quarter of 2026, from $150.6 million for the corresponding prior year period, primarily driven by an increase in Oncology test volume, which grew 47% over the prior year period, and an increase in reimbursement for our oncology tests. Screening revenue grew over 600% to $41.6 million for the first quarter of 2026, from $5.7 million for the corresponding prior year period, driven primarily by an increase in Shield screening test volume, which grew to approximately 44,000 tests in the first quarter of 2026, from approximately 9,000 tests in the prior year period. The increase was also attributable to an increase in reimbursement for our Shield screening tests. Biopharma and Data revenue grew 17% to $53.0 million for the first quarter of 2026, from $45.4 million for the corresponding prior year period.

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.
