Ultra Clean Holdings, Inc. revised revenue guidance for the fourth quarter of 2022. For the quarter, the company expects revenue to be in the range of $560 million to $570 million against previous guidance range of $600 million to $650 million. The guidance change is the result of customer order modifications related to the weakening industry environment and manufacturing output declines due to the resurgence of COVID in UCT's China facility.

These circumstances were unforeseen when the original guidance was provided, and the Company believes this does not represent a change to its competitive position or capabilities.
