“We ended the third quarter with revenue growth of 22%, driven by strong year-over-year growth in clinical volume. We are starting to see the impact of coverage decisions on Guardant360, with uplifts in ASPs and additional tailwinds further strengthening the financial profile of our Therapy Selection business,” said Helmy Eltoukhy, co-founder and co-CEO. “We recently presented exciting MRD data, further demonstrating the clinical utility of our Reveal blood test. We look forward to a strong finish to the year.”

“We are continuing to make steady progress in our screening business with our Shield blood test,” said AmirAli Talasaz, co-founder and co-CEO. “At our recent investor day, we shared some promising new clinical validation data on the next generation of our Shield test. We are also advancing our progress in lung and other indications as we develop Shield into a multi-cancer early detection test.”

Third Quarter 2023 Financial Results

Revenue was $143.0 million for the three months ended September 30, 2023, a 22% increase from $117.4 million for the three months ended September 30, 2022. Precision oncology revenue grew 31%, driven predominantly by an increase in clinical testing volume and biopharma sample volume, which grew 35% and 11%, respectively, over the prior year period. In addition, our clinical testing revenue for the three months ended September 30, 2023 includes a payment of $3.6 million from Medicare related to a successful appeal for claims dated between 2018 and 2020. Development services and other revenue decreased by 37%, primarily due to the timing and amount of milestones related to our partnership agreements and companion diagnostics collaboration projects with biopharmaceutical customers, as well as a reduction in royalty revenue during the three months ended September 30, 2023.

Gross profit, or total revenue less cost of precision oncology testing and cost of development services and other, was $85.4 million for the third quarter of 2023, an increase of $8.5 million from $76.9 million for the corresponding prior year period. Gross margin, or gross profit divided by total revenue, was 60%, as compared to 66% for the corresponding prior year period. Precision oncology gross margin was 60% in the third quarter of 2023, as compared to 61% in the prior year period. The reduction is primarily due to changes in product mix. Development services and other gross margin was 59% in the third quarter of 2023, as compared to 93% in the prior year period. The change is primarily due to the inclusion of the cost of processing Shield LDT samples as part of our screening market development activities, for which we are currently booking minimal revenue.

Operating expenses were $199.0 million for the third quarter of 2023, as compared to $221.5 million for the corresponding prior year period. Non-GAAP operating expenses were $177.3 million for the third quarter of 2023, as compared to $200.5 million for the corresponding prior year period.

Net loss was $86.1 million for the third quarter of 2023, as compared to $162.0 million for the corresponding prior year period. Net loss per share was $0.73 for the third quarter of 2023, as compared to $1.58 for the corresponding prior year period. The year-over-year reduction in net loss is primarily due to a $31.1 million year-over-year improvement in our loss from operations, a $29.9 million positive change in unrealized gains and losses, and a $9.9 million increase in interest income.

Non-GAAP net loss was $79.2 million for the third quarter of 2023, as compared to $120.8 million for the corresponding prior year period. Non-GAAP net loss per share was $0.67 for the third quarter of 2023, as compared to $1.18 for the corresponding prior year period.

Adjusted EBITDA loss was $79.7 million for the third quarter of 2023, as compared to a $112.8 million loss for the corresponding prior year period.

Free cash flow for the third quarter of 2023 was negative $80.2 million. Cash, cash equivalents and marketable debt securities were $1.2 billion as of September 30, 2023.

2023 Guidance

Guardant Health now expects full year 2023 revenue to be in the range of $553 to $556 million, representing growth of 23% to 24% compared to full year 2022. Guardant Health continues to expect full year 2023 operating expenses to be below full year 2022, driven by efficiency measures and continued leverage of its existing infrastructure, and free cash flow to be approximately negative $350 million in 2023.

Webcast Information

Guardant Health will host a conference call to discuss the third quarter and full year 2023 financial results after market close on Monday, November 6, 2023 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 precision oncology testing, non-GAAP cost of development services and other, 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, changes in estimated fair value of noncontrolling interest liability, contingent consideration, acquisition related expenses, amortization of intangible assets, fair value adjustments on marketable equity securities, impairment of non-marketable equity securities and other related assets, 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; changes in estimated fair value of noncontrolling interest liability; adjustments relating to contingent consideration; and, if applicable in a reporting period, acquisition-related expenses, and other non-recurring items. Free cash flow is defined as net cash used in operating activities in the period less purchase 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 other items because we believe that these income (expenses) do not reflect expected future operating expenses. 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.
