ADPT Adaptive Biotechnologies Corporation

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 September 30, 2023.

“We have two compelling businesses in MRD and Immune Medicine, which continue to make significant progress in divergent ways,” said Chad Robins, chief executive officer and co-founder of Adaptive Biotechnologies. “Given the advancements achieved to date by each business and their respective investment needs, we are conducting a review of strategic alternatives to maximize value for our patients and shareholders.”

Recent Highlights

• Strategic review underway with Goldman Sachs to maximize the value of the MRD and Immune Medicine businesses.
• Revenue for the third quarter 2023 was $37.9 million, representing a 21% decrease from the third quarter 2022 driven primarily by a 61% reduction in GNE amortization and a 14% decrease in MRD pharma services and IM pharma services largely due to biopharmaceutical industry headwinds.
• clonoSEQ test volume in the third quarter 2023 grew 56% to 15,072 tests delivered versus the third quarter of prior year.
• Immune Medicine achieved a key milestone with the discovery of a novel target in multiple sclerosis, which validates our target discovery approach in autoimmune disorders.
• Operating expenses, excluding cost of revenue, for the third quarter 2023 decreased 11% versus the same period last year as a result of continued operating efficiencies efforts.

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 areas: Minimal Residual Disease (MRD) and Immune Medicine. Our commercial products and clinical pipeline enable the diagnosis, monitoring, and treatment of diseases such as cancer, autoimmune disorders, and infectious diseases. 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, restructuring expense and share-based compensation expense. We have provided a reconciliation 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 to evaluate the financial performance of our business and the effectiveness of our business strategies. We present Adjusted EBITDA 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 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 in the presentation of Adjusted EBITDA. In particular, we expect to incur meaningful share-based compensation expense in the future. Other limitations include that 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; 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 March 2022 restructuring and reduction in workforce.

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