Adaptive Biotechnologies Reports First Quarter 2026 Financial Results

SEATTLE, May 05, 2026 (GLOBE NEWSWIRE) – Adaptive Biotechnologies Corporation (“Adaptive Biotechnologies”) (Nasdaq: ADPT), a commercial stage biotechnology company that aims to translate the genetics of the adaptive immune system into clinical products to diagnose and treat disease, today reported financial results for the quarter ended March 31, 2026.

“We delivered strong first quarter results based on accelerating adoption of MRD across both clinical testing and drug development. Our performance reinforces our market leadership position and the differentiated value of our platform,” said Chad Robins, chief executive officer and co-founder of Adaptive Biotechnologies. “With disciplined execution and multiple growth drivers in place, we are well positioned to sustain our growth trajectory and create long-term value.”

Recent Highlights

Revenue for the first quarter of 2026 was $70.9 million. The MRD business, which contributed 95% of revenue, grew 53% versus the first quarter of 2025.

clonoSEQ® test volume in the first quarter of 2026 increased 41% to 32,595 tests delivered versus the first quarter of 2025.

Recognized $9.0 million in MRD pharma regulatory milestone revenue, the first U.S. primary endpoint milestone.

Raising full year 2026 MRD revenue guidance to a new range of $260 million to $270 million, implying annual growth of 22% to 27%.

First Quarter 2026 Financial Results

Revenue was $70.9 million for the quarter ended March 31, 2026, representing a 35% increase from the first quarter in the prior year. Excluding revenue recognized under the Genentech Agreement, which did not generate revenue in the quarter ended March 31, 2026, revenue for the current quarter increased 45% from the first quarter in the prior year. MRD revenue was $67.1 million for the quarter, representing a 53% increase from the first quarter in the prior year. Immune Medicine revenue was $3.8 million for the quarter, representing a 57% decrease from the first quarter in the prior year. Excluding revenue from the Genentech Agreement, Immune Medicine revenue for the quarter ended March 31, 2026 decreased 26% from the first quarter in the prior year.

Operating expenses for the first quarter of 2026 were $90.1 million, compared to $82.0 million in the first quarter of the prior year, representing an increase of 10%.

Interest and other income, net was $2.1 million for the first quarter of 2026, compared to $2.7 million in the first quarter of the prior year. Interest expense from our revenue interest purchase agreement was $2.9 million in both the first quarter of 2026 and the first quarter of the prior year.

We expect full year total company operating expenses, including cost of revenue, to be between $350 million and $360 million.

About Adaptive Biotechnologies

Adaptive Biotechnologies (“we” or “our”) is a commercial-stage biotechnology company focused on harnessing the inherent biology of the adaptive immune system to transform the diagnosis and treatment of disease. We believe the adaptive immune system is nature’s most finely tuned diagnostic and therapeutic for most diseases, but the inability to decode it has prevented the medical community from fully leveraging its capabilities. Our proprietary immune medicine platform reveals and translates the massive genetics of the adaptive immune system with scale, precision and speed. We apply our platform to partner with biopharmaceutical companies, inform drug development, and develop clinical diagnostics across our two business segments: Minimal Residual Disease (MRD) and Immune Medicine. Our commercial products and clinical pipeline enable the diagnosis, monitoring, and treatment of diseases such as cancer and autoimmune disorders. Our goal is to develop and commercialize immune-driven clinical products tailored to each individual patient.

Forward-Looking Statements

This press release contains forward-looking statements that are based on management’s beliefs and assumptions and on information currently available to management. All statements contained in this release other than statements of historical fact are forward-looking statements, including statements regarding our ability to develop, commercialize and achieve market acceptance of our current and planned products and services, our research and development efforts and other matters regarding our business strategies, use of capital, results of operations and financial position and plans and objectives for future operations.

In some cases, you can identify forward-looking statements by the words “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing” or the negative of these terms or other comparable terminology, although not all forward-looking statements contain these words. These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. These risks, uncertainties and other factors are described under "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and elsewhere in the documents we file with the Securities and Exchange Commission from time to time. We caution you that forward-looking statements are based on a combination of facts and factors currently known by us and our projections of the future, about which we cannot be certain. As a result, the forward-looking statements may not prove to be accurate. The forward-looking statements in this press release represent our views as of the date hereof. We undertake no obligation to update any forward-looking statements for any reason, except as required by law.

Use of Non-GAAP Financial Measure

To supplement our unaudited condensed consolidated statements of operations and unaudited condensed consolidated balance sheets, which are prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”), this press release also includes references to Adjusted EBITDA, which is a non-GAAP financial measure that we define as net loss attributable to Adaptive Biotechnologies Corporation adjusted for interest and other income, net, interest expense, income tax (expense) benefit, depreciation and amortization expense, impairment costs for long-lived assets, restructuring expense and share-based compensation expense. We define our segment Adjusted EBITDA in the same way to the extent the net loss attributable to Adaptive Biotechnologies Corporation and adjustments are allocable to each segment. We have provided reconciliations of net loss attributable to Adaptive Biotechnologies Corporation, the most directly comparable GAAP financial measure, to Adjusted EBITDA at the end of this press release.

Management uses Adjusted EBITDA, including segment Adjusted EBITDA, to evaluate the financial performance of our business and segments and to evaluate the effectiveness of our strategies. We present these figures because we believe it is frequently used by analysts, investors and other interested parties to evaluate companies in our industry and it facilitates comparisons on a consistent basis across reporting periods. Further, we believe it is helpful in highlighting trends in our operating results because it excludes items that are not indicative of our core operating performance.

Adjusted EBITDA, including segment Adjusted EBITDA, has limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. We may in the future incur expenses similar to the adjustments we make. In particular, we expect to incur meaningful share-based compensation expense in the future. Other limitations include that Adjusted EBITDA, including segment Adjusted EBITDA, does not reflect:

all expenditures or future requirements for capital expenditures or contractual commitments;

changes in our working capital needs;

interest expense, which is an ongoing element of our costs to operate;

income tax (expense) benefit, which may be a necessary element of our costs and ability to operate;

the costs of replacing the assets being depreciated and amortized, which will often have to be replaced in the future;

the noncash component of employee compensation expense;

long-lived assets impairment costs; and

the impact of earnings or charges resulting from matters we consider not to be reflective, on a recurring basis, of our ongoing operations, such as our restructuring activities and reductions in workforce.

In addition, Adjusted EBITDA, including segment Adjusted EBITDA, may not be comparable to similarly titled measures used by other companies in our industry or across different industries.
