LOUISVILLE, CO, May 4, 2026 – Biodesix, Inc. (Nasdaq: BDSX), a leading diagnostic solutions company, today announced its financial and operating results for the first quarter ended March 31, 2026.

"Biodesix delivered exceptional first quarter results that reflect strong momentum across both our Diagnostic Testing and our Development Services business,” said Scott Hutton, Chief Executive Officer. “Test volumes grew 29%, Development Services revenue doubled, and average revenue per test increased through expanded payer coverage and improved revenue cycle management, driving total revenue growth of 42% year over year. We were also recognized as a Top Workplace for the third consecutive year, reinforcing that our culture is not aspirational, its operational. Our first quarter results reflect a disciplined culture of execution in service to our partners, healthcare providers, and the patients they serve. With strong performance across both business lines and continued operational leverage, we are raising our full‑year 2026 guidance and remain on a clear path toward profitability."

Business and Financial Highlights for the First Quarter 2026

•

Diagnostic Testing revenue was $22.3 million in the first quarter, representing 37% year-over-year growth, driven by a 29% increase in test volumes to 17,800 and higher average revenue per test. The improvement in average revenue per test was primarily attributable to expanded payer coverage and enhancements to revenue cycle management;

•

Development Services revenue of $3.3 million in the first quarter 2026, representing a 99% increase year over year, driven by continued execution on existing contracts and the addition of new Development Services agreements;

•

Total revenue of $25.6 million in the first quarter 2026, an increase of 42% over the respective prior year comparable period;

•

Gross margin was 84% in the first quarter, including a one‑time recovery of $0.4 million related to previously paid sales and use taxes. Excluding this one‑time item, gross margin was 82%, representing a 300‑basis‑point improvement over the prior‑year period. Margin expansion was driven by higher Diagnostic Testing volumes, improved average revenue per test, and continued optimization of laboratory workflows, resulting in a lower cost per test;

•

Operating expenses (excluding direct costs and expenses) of $27.6 million for the first quarter 2026, an increase of 18% over the respective prior year comparable period. Sales, marketing, and general administrative investment increased 19% to support the 42% revenue growth delivered in the first quarter. The Company expects continued operating leverage as our expanded sales team advances along the productivity curve and converts growing experience into sustained performance.

Includes non-cash stock compensation expense of $1.1 million during the first quarter 2026, an increase of 15% over the respective prior year comparable period;

•

Net loss of $7.8 million for the first quarter 2026, an improvement of 30% over the respective prior year comparable period;

•

Adjusted EBITDA was a loss of $4.1 million in Q1 2026, 35% improvement from Q1 2025;

•

Cash and cash equivalents of $25.6 million, an increase of 35% over the period ending December 31, 2025. Change in cash included $16.8 million of at-the-market net proceeds, partially offset by the planned cash outflows that occur annually during the first quarter of the year.

2026 Financial Outlook

For full year 2026, the Company expects total revenue of $108–114 million, with the midpoint representing approximately 25% growth over 2025. Biodesix expects continued progress toward achieving and maintaining Adjusted EBITDA profitability, driven by increasing sales productivity, expanded clinical evidence supporting the Nodify Lung tests, growth in the Development Services pipeline, and demonstrated operating leverage.

Use of Non-GAAP Financial Measure

Biodesix reported results are presented in accordance with generally accepted accounting principles in the United States (GAAP). Biodesix has provided in this press release financial information that has not been prepared in accordance with GAAP. Biodesix uses the non-GAAP financial measure, Adjusted EBITDA, internally in analyzing its financial results and believes that use of this non-GAAP financial measure is useful to investors as an additional tool to evaluate ongoing operating results and trends and in comparing Biodesix financial results with other companies in its industry, many of which present similar non-GAAP financial measures. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with Biodesix financial statements prepared in accordance with GAAP. A reconciliation of Biodesix historical non-GAAP financial measure to the most directly comparable GAAP measure has been provided in the financial statement tables included in this press release, and investors are encouraged to review the reconciliation.

Adjusted EBITDA is a key performance measure that our management uses to assess our financial performance and is also used for internal planning and forecasting purposes. We believe that this non-GAAP financial measure is useful to investors and other interested parties in analyzing our financial performance because it provides a comparable overview of our operations across historical periods. In addition, we believe that providing Adjusted EBITDA, together with a reconciliation of Net loss to Adjusted EBITDA, helps investors make comparisons between our Company and other companies that may have different capital structures, different tax rates, and/or different forms of employee compensation.

Adjusted EBITDA is used by our management team as an additional measure of our performance for purposes of business decision-making, including managing expenditures. Period-to-period comparisons of Adjusted EBITDA help our management identify additional trends in our financial results that may not be shown solely by period-to-period comparisons of Net loss or Loss from operations. Our management recognizes that Adjusted EBITDA has inherent limitations because of the excluded items and may not be directly comparable to similarly titled metrics used by other companies.

We calculate Adjusted EBITDA as Net loss adjusted to exclude interest, income tax expense, if any, depreciation and amortization, share-based compensation expense, loss on debt extinguishments, net, change in fair value of warrant liabilities, net, other income, net, and other non-recurring items. Non-recurring items are excluded as they are not representative of our underlying operating performance. Adjusted EBITDA should be viewed as a measure of operating performance that is a supplement to, and not a substitute for Loss from operations, Net loss, and other GAAP measures.
