I-Mab Provides Updates Regarding Holding Foreign Companies Accountable Act

SHANGHAI and GAITHERSBURG, Md., March 15, 2022 /PRNewswire/ -- 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 provides updates on the recent development relating to the Holding Foreign Companies Accountable Act (the "HFCAA") and its implementation. The U.S. Securities and Exchange Commission (the "SEC") released on March 8, 2022 a provisional list of issuers identified as "Commission-Identified Issuers" under the HFCAA because the Public Company Accounting Oversight Board (the "PCAOB") is unable to inspect or investigate completely the registered public accounting firms that issued audit reports for those companies. As of the date of this press release, I-Mab is not on this list.

I-Mab has taken proactive measures in response. The Company has implemented additional business processes and control changes to meet the requirements set forth in the HFCAA. The measures include, subject to compliance with applicable rules and regulations, engaging an accounting firm that is subject to inspection by the PCAOB for the preparation of its audit reports commencing from the fiscal year of 2022. Such compliance measures are expected to be effective in the 2022 annual report.

The China Securities Regulatory Commission and the Ministry of Finance of the People's Republic of China have noted that they have been engaging with the PCAOB and have made positive progress. I-Mab will closely follow the development as the two parties work jointly to reach cooperation arrangements that better protect global investors and promote the stability and robustness of the two capital markets.

Additionally, the Company is considering all viable options to offer the Company's existing shareholders additional trading flexibility and will make public announcement(s) to disclose any material updates and progress with respect to its efforts in this regard when appropriate. As previously disclosed in the Company's press release dated December 7, 2021, the Company is pursuing dual listing on the Main Board of the Stock Exchange of Hong Kong Limited.  The Company believes that the dual listing will offer the Company's existing ADS holders the enhanced trading flexibility the HKEX offers in addition to the Nasdaq and complement its current investor base. The Hong Kong dual listing is conditional upon and subject to, among other things, market conditions and the obtaining of the necessary regulatory approvals.

This announcement is for information purposes only and does not constitute, or form part of, an invitation or offer to acquire, purchase or subscribe to any securities of the Company. The Company cautions its shareholders and others considering trading the Company's securities that substantial uncertainties remain with respect to the future development of the issue and there may be a number of factors out of the Company's control.
