Burning Rock Announces Change to ADS Ratio

GUANGZHOU, China, April 26, 2024 — Burning Rock Biotech Limited (NASDAQ: BNR and LSE: BNR, the “Company” or “Burning Rock”), a company focused on applying next generation sequencing (NGS) technology in the field of precision oncology, today announced that it will change the ratio of its American depositary shares (the “ADSs”) to Class A ordinary shares from one (1) ADS representing one (1) Class A ordinary share to one (1) ADS representing ten (10) Class A ordinary shares (the “ADS Ratio Change”). The ADS Ratio Change is expected to become effective on or about May 15, 2024 (the “Effective Date”). For Burning Rock’s ADS holders, the ADS Ratio Change will have the same effect as a one-for-ten reverse ADS split. There will be no change to the Company’s Class A ordinary shares. On the Effective Date, registered holders of the Company’s ADSs held in certificated form will be required on a mandatory basis to surrender their certificated ADSs to Citibank, N.A., the depositary bank (the “Depositary”), for cancellation and will receive one (1) new ADS in exchange for every ten (10) existing ADSs surrendered. Holders of uncertificated ADSs in the Direct Registration System and The Depository Trust Company will have their ADSs automatically exchanged and need not take any action. The exchange of every ten (10) then-held (existing) ADSs for one (1) new ADS will occur automatically at the Effective Date, with the then-held ADSs being cancelled and new ADSs being issued by the Depositary. Burning Rock’s ADSs will continue to be traded on the NASDAQ Global Market and London Stock Exchange under the symbol “BNR”. No fractional new ADSs will be issued in connection with the change in the ADS Ratio Change. Instead, fractional entitlements to new ADSs will be aggregated and sold by the Depositary and the net cash proceeds from the sale of the fractional ADS entitlements will be distributed to the applicable ADS holders by the Depositary, in each case in accordance with the Depositary’s then current procedures and practices and after any deductions as provided in the deposit agreement between the Company and the Depositary for the ADSs. As a result of the ADS Ratio Change, the ADS price is expected to increase proportionally, although the Company can give no assurance that the ADS price after the ADS Ratio Change will be equal to or greater than ten times the ADS price before the change.
