Cheetah Mobile Inc. (NYSE: CMCM) (“Cheetah Mobile” or the “Company”) has become aware that on September 21, 2022, the Company’s Chairman of the Board and Chief Executive Officer, Mr. Sheng Fu, reached a resolution with the U.S. Securities and Exchange Commission (the “SEC”) of the previously disclosed investigation relating to the Company’s disclosures for fiscal year 2015 regarding its relationship with one of its advertising business partners, Rule 10b5-1 trading plans entered into by officers and directors, and sales of the Company’s American depositary shares under a trading plan in 2016.

To Cheetah Mobile’s knowledge, pursuant to the terms of the settlement, Mr. Fu has consented to the entry of a cease and desist order with the SEC on a “neither admit nor deny” basis that would require him to refrain from violating (i) Section 17(a)(2) and (3) of the Securities Act of 1933, and (ii) Sections 10(b) and 13(a) of the Securities Exchange Act of 1934 and Rules 10b-5, 12b-20, and 13a-1 thereunder. The terms of the settlement between Mr. Fu and the SEC also include payment of a civil money penalty in the amount of $556,580 and certain compliance undertakings.

The Company is not a party to the settlement. The SEC informed the Company that it has concluded its investigation with respect to the Company and does not intend to recommend an enforcement action.
