Burning Rock Reports First Quarter 2023 Financial Results

GUANGZHOU, China, May 30, 2023—Burning Rock Biotech Limited (NASDAQ: BNR and LSE: BNR, the “Company” or “Burning Rock”), a company focused on the application of next generation sequencing (NGS) technology in the field of precision oncology, today reported financial results for the three months ended March 31, 2023.

Recent Business Updates

•	Minimal Residual Disease (MRD)
•	Results of the MEDAL (MEthylation Based Dynamic Analysis for Lung Cancer) study were published at the American<br>Association for Cancer Research Annual Meeting 2023 (“AACR 2023”). Through parallel testing and comparison of Burning Rock’s personalized MRD test brPROPHET^™^ and fixed MRD<br>assays, the objective of this study was to establish the best technique and application strategy of dynamic MRD detection for prognosis prediction and disease assessment among NSCLC patients. It shows that brPROPHET^™^ detected more MRD events with ultra-low ctDNA abundance yet meaningful prognostic significance. In addition, the dynamic change of longitudinal MRD was<br>evaluated to explore the positive predictive value (PPV) and negative predictive value (NPV) of MRD detections over time, providing important insights for guiding the standardization of future surveillance applications.
---	---
•	The results of the clinical performance of brPROPHET^™^<br>in patients with resectable gastric cancer and biliary tract cancer were also released at AACR 2023.
---	---
•	Pharma Services
---	---
•	Total value of new contracts entered into during the first quarter of 2023 amounted to RMB75 million,<br>representing a 27% increase from the same period in 2022.

Non-GAAP Measures

In evaluating the business, the company considers and uses non-GAAP measures, such as non-GAAP gross profit and non-GAAP gross margin, as supplemental measures to review and assess operating performance. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The company defines non-GAAP gross profit as gross profit excluding depreciation and amortization. The company defines non-GAAP gross margin as gross margin excluding depreciation and amortization.

The company presents these non-GAAP financial measures because they are used by management to evaluate operating performance and formulate business plans. The company believe non-GAAP gross profit and non-GAAP gross margin excluding non-cash impact of depreciation and amortization reflect the company’s ongoing business operations in a manner that allows more meaningful period-to-period comparisons.
