Update on Status under Holding Foreign Companies Accountable Act

Hong Kong, Shanghai & Florham Park, NJ - Thursday, March 31, 2022: HUTCHMED (China) Limited ("HUTCHMED" or the "Company") (Nasdaq/AIM:HCM; SEHK:13) provides an update on its status under the Holding Foreign Companies Accountable Act (the "Act"), following the Company's initial announcement on March 11, 2022.

On March 30, 2022, as expected following its adoption of implementing rules pursuant to the Act, the U.S. Securities and Exchange Commission (the "SEC") added HUTCHMED to its conclusive list of issuers identified under the Act. The Company was provisionally named as a Commission-Identified Issuer on March 8, 2022, following the filing of its annual report on Form 20-F with the SEC on March 3, 2022. The SEC has estimated that 273 registrants might be identified under the Act as part of its review of registrants in calendar year 2020. We anticipate that other similarly situated U.S.-listed companies with operations in Hong Kong and other parts of China will be added once they file their annual reports with the SEC.

As the Company continues to monitor market developments and evaluate all strategic options, with the appropriate counsel and guidance, it would like to note that this update has no impact on business operations.

HUTCHMED understands that the motivation behind the Act is to ensure appropriate transparency and disclosure so that investors are able to make informed investment decisions. This we fully support and have been committed to ever since our initial listing in London in 2006. As always, we will continue complying with relevant laws and regulations in all the jurisdictions we are listed. Furthermore, we are working to maintain communication with the China Securities Regulatory Commission (CSRC) to understand if there are further updates on their discussions with the US authorities regarding how China-based companies may be able to meet the requirements of the Act. We will continue to evaluate all options to remain listed in the US, including assessing the merits of appointing an auditor outside of China if and when the contribution of our international business to the Group exceeds our China business.

The Company's American depositary shares, each of which represents five ordinary shares, continue to trade uninterrupted on the Nasdaq Global Select Market. Its ordinary shares are admitted for trading on the AIM market. In addition, on June 30, 2021, the Company completed a primary listing of its ordinary shares on the Main Board of The Stock Exchange of Hong Kong Limited ("HKEX") under the stock code "13". The shares listed on HKEX and AIM are fully fungible with the shares represented by the Company's American depositary shares.

About the Holding Foreign Companies Accountable Act

The Act is part of a continued regulatory focus in the United States on access to audit and other information currently protected by national law, in particular China's, and the preparation of such list is provided for in the Act and the SEC's implementing rules. The Act requires the SEC to prohibit the securities of any issuer which is required to file periodic reports under the U.S. Securities Exchange Act of 1934, which includes the Company, from being traded on any of the U.S. securities exchanges, including the Nasdaq Stock Market, or on any over-the-counter market if the auditor of such issuer's financial statements is not subject to inspection by the U.S. Public Company Accounting Oversight Board ("PCAOB") for three consecutive years, beginning in 2021. Under the current terms of the Act, the Company's American depositary shares will be delisted from the Nasdaq Stock Market in early 2024, unless the Act is amended to exclude the Company or the PCAOB is able to conduct a full inspection of the Company's auditor during the required timeframe. In addition, legislation is being considered in the United States to shorten the number of non-inspection years from three years to two.
