Veracyte s executive chairwoman. Our prior strategic acquisitions brought exclusive global access to a best-in-class diagnostic platform and a significantly

expanded cancer testing menu. We believe HalioDx will help fuel our global growth by accelerating IVD test development and manufacturing operations in Europe and by expanding our scientific expertise into the emerging immuno-oncology field.

Additionally, their commercial-stage colon cancer immune response test will broaden our testing menu to 8 of the top 10 cancers.

and contribute to precision medicine. The company provides a unique range of immune assessment solutions, including its flagship Immunoscore assay for assessing the immune contexture of a

tumor as a key determinant of patients outcomes and response to cancer treatments. HalioDx has developed a unique biopharma partnering ecosystem for the identification of clinically relevant biomarker signatures, the demonstration of their

utility in clinical trials and the development and commercialization of resulting IVD and companion diagnostic tests. The company operates CLIA-certified laboratories in the United States and France, as well as a manufacturing facility in France

Strategic Benefits for Global Growth

Marc Stapley, Veracyte s chief executive officer, said, Adding HalioDx to Veracyte is a strategic

investment that we believe will position the company to unlock its growth potential. With this acquisition, we will have the parts needed to expand our business globally. Veracyte plays an increasingly vital role in advancing patient outcomes and

care, and I m excited to bring my experience building and leading complex global organizations to the company. I look forward to partnering with Bonnie, who will oversee completion of this acquisition and lead the strategic integration, and to

welcoming the HalioDx team to Veracyte so we can work together to improve care for patients all over the world.

Veracyte is a leading global

diagnostics company with strong expertise in genomic testing through both centralized and distributed tests, said Vincent Fert, HalioDx s chairman and chief executive officer. We are aligned with their mission to improve care for

patients and believe our capabilities and expertise in immuno-oncology and diagnostic development and manufacturing are highly complementary to their business and strategic vision. The transaction gives us the opportunity to significantly accelerate
