EXHIBIT INDEX

Exhibit 99.1

Kingsoft Cloud Provides Update on its Status under the Holding Foreign Companies Accountable

Act

BEIJING, China, May 10, 2022 – Kingsoft Cloud Holdings Limited (“we,” “Kingsoft Cloud” or the “Company”) (NASDAQ: KC), a leading independent cloud service provider in China, today announced that the Company is aware that it was identified by the U.S. Securities and Exchange Commission (“SEC”) on its provisional list under the Holding Foreign Companies Accountable Act (the “HFCAA”) on May 9, 2022, following the Company’s filing of its annual report on Form 20-F for the fiscal year ended December 31, 2021 (“2021 Form 20-F”).

This identification indicates that the SEC has determined the Company used an auditor, whose working paper cannot be inspected or investigated completely by the Public Company Accounting Oversight Board of the United States (“PCAOB”), to issue the audit opinion for the Company’s financial statements included in 2021 Form 20-F.

Under the HFCAA, the trading of a company’s securities on a U.S. stock exchange will be prohibited only if the company has been identified by the SEC for three consecutive years due to PCAOB’s inability to inspect the auditor’s working paper because of a position taken by an authority in a foreign jurisdiction. Given this is the first identification, the Company’s active listing and trading status on the NASDAQ remains unchanged.

The Company is closely monitoring the evolving regulatory development to ensure compliance with all applicable laws and regulations in all relevant jurisdictions including both China and the United States. In the meantime, to provide our shareholders with greater liquidity and protection, as previously announced, the Company is exploring a dual listing on the Main Board of the Hong Kong Stock Exchange, subject to regulatory approvals and market and other conditions ^[1].

The Company will continue its focus on sustainable development to drive value creation for all stakeholders through strong Environmental, Social, and Governance practices. To name a few, we have appointed our first female independent director as a step forward to enhance board diversity, and have endeavored to enhance oversight on ESG matters at the board level.

^[1] This disclosure does not, and is not intended to, constitute an offer to sell or a solicitation of an offer to purchase any of our securities in the United States, Hong Kong or elsewhere, and it does not, and is not intended to, constitute an offer, solicitation or sale of any securities in any jurisdiction in which such an offer, solicitation or sale would be unlawful. Any offers, solicitations or offers to buy, or any sales of securities will be made in accordance with the requirements of the Securities Act of 1933, as amended as well as other applicable laws and regulations.
