BEIJING, January 10, 2022 – Genetron Holdings Limited (“Genetron Health” or the “Company”, Nasdaq: GTH), a leading precision oncology platform company in China that specializes in offering molecular profiling tests, early cancer screening products and companion diagnostics development, today reiterated its full year 2021 revenue guidance. The Company expects full year 2021 revenue to be around RMB 530 million, representing approximately 25% growth over the Company’s full year 2020 revenue.

“We are pleased with our accomplishments in 2021 amid a challenging operating environment that continues to be heavily impacted by the COVID-19 pandemic,” said Mr. Sizhen Wang, co-founder and CEO of Genetron Health. “Throughout 2021 we experienced strong growth led by our in-hospital IVD sales, advanced our early screening registrational strategy for hepatocellular carcinoma, developed a multi-omics blood-based CRC early screening assay, established partnerships with AstraZeneca R&D China and Fosun Pharma to develop and commercialize MRD products, and expanded the body of clinical evidence and publications that reinforce and support the clinical value of our tests. These accomplishments have positioned Genetron favorably to drive meaningful growth in the coming years.”

The Company will discuss its fourth quarter and full year 2021 results during its earnings call in March.
