Ultra Clean Holdings, Inc. (UCTT) Securities Lawsuit Class Period 

May 6, 2024 to February 24, 2025, inclusive. 

Investors who acquired Ultra Clean securities during the class period may be eligible for compensation.

Ultra Clean Holdings, Inc. (UCTT) Lawsuit Allegations 

In May 2024, Ultra Clean announced its Q1-24 financial results. The Company touted “elevated demand” in China and substantially increased revenue from Chinese original equipment manufacturers (OEMs). In July 2024, the Company released its Q2-24 financial results, again emphasizing strong Chinese growth and expectations for continued growth. These overwhelmingly positive statements persisted into October, when the Ulra Clean executives projected growth into 2025.   

Plaintiffs alleged Ultra Clean misled investors and its executives made deceptive, false, and misleading statements about demand for Ultra Clean's products. Specifically, Plaintiffs accuse Ultra Clean and its executives of making false or deceptive statements about Ultra Clean’s demand in the domestic Chinese market and failing to disclose inventory issues that negatively affected Chinese demand.  

The Truth Emerges 

In February 2025, the truth about soft Chinese business conditions came to light following release of Ultra Clean’s Q4-24 financial results. During the associated earnings call, the Company's executives revealed  “unexpected demand softness” in China. They attributed this downturn to extended timelines with a key customer, inventory stockpiling, and decreased demand from critical customers. These contrasted starkly with the overly rosy picture of China given just a few months earlier. 

Market Reaction  

Investors reacted negatively to this news. Ultra Clean’s common stock price fell 28% in just one day after this news.   

Analysts reacted immediately about the Company's sudden about-face, with several analysts substantially cutting their target prices. 

A class action lawsuit has been filed against Ultra Clean Holdings, Inc. (NASDAQ: UCTT) and certain of its officers.
