I-Mab Provides Updates on Status under Holding Foreign Companies Accountable Act

SHANGHAI and GAITHERSBURG, MD. May 5, 2022 – I-Mab (“I-Mab” or the “Company”) (Nasdaq: IMAB), a clinical-stage biopharmaceutical company committed to the discovery, development, and commercialization of novel biologics, today provided updates on its status under the Holding Foreign Companies Accountable Act (the “HFCAA”).

The Company is aware that the U.S. Securities and Exchange Commission (the “SEC”) provisionally identified I-Mab as a “Commission-Identified Issuer” after the Company filed its annual report on Form 20-F for the fiscal year ended December 31, 2021 with the SEC on April 29, 2022, which included an audit report issued by a public accounting firm that the Public Company Accounting Oversight Board (the “PCAOB”) has determined that it is unable to inspect completely.

I-Mab understands that the SEC made such identification pursuant to the HFCAA and its implementation rules issued thereunder, which will not directly result in the delisting of the Company’s American Depositary Shares (“ADSs”) from Nasdaq. Pursuant to the HFCAA, the SEC will prohibit a company’s shares or ADSs from being traded on a national stock exchange or in the over-the-counter trading market in the United States if the Company has been identified by the SEC for three consecutive years due to the PCAOB’s inability to inspect the registered public accounting firm’s working paper related to such company.

I-Mab is in the process of engaging a selected U.S.-based independent registered public accounting firm as its principal auditor that is subject to the inspection by the PCAOB. This firm also needs to comply with the applicable rules and regulations concerning information confidentiality and archives administration for compliance purposes in China. The Company aims to complete the engagement in the second half of 2022 and subsequent change of its principal auditor is expected to take place in conjunction with the filing of its annual report for the fiscal year ended December 31, 2022.
