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.

Important Note Regarding Preliminary, Unaudited Financial Results

Adaptive Biotechnologies has not completed the preparation of its financial statements for the first quarter of 2024. The financial disclosures referenced in this release for the first quarter are preliminary and are thus inherently uncertain and subject to change as we complete our financial close processes for the first quarter of 2024. Adaptive Biotechnologies is in the process of completing its customary quarter-end close and review procedures as of and for the quarter ended March 31, 2024, and there can be no assurance that final results for this period will not differ from these estimates.
