According to the Complaint, Ultra Clean Holdings, Inc. is a developer and supplier of subsystems, components, parts, and ultrahigh purity cleaning and analytical services primarily for the semiconductor industry. This class action was filed against Ultra Clean and two of its Officers.

During the Class Period, Defendants provided investors with material information concerning the elevated demand from Chinese original equipment manufacturers (OEMs) and in the general Chinese domestic market for Ultra Clean’s products throughout the fiscal year 2024. Defendants’ statements included, among other things, reports of increased demand for the Company’s products and services in the domestic Chinese market and reports of increased revenue, including revenue doubling with no signs of slowing down, due to the elevated demand in China for Ultra Clean’s products and services.

The Complaint alleges Defendants provided these overwhelmingly positive statements to investors while, at the same time, disseminating materially false and misleading statements and/or concealing material adverse facts concerning the true state of the demand for Ultra Clean’s products and services in the domestic Chinese market; notably, that the Company was facing a customer ramp issue with one of its critical customers, as well as a combination of inventory and demand corrections, which, ultimately, caused weakness for Ultra Clean in China.
