Summary

Ultra Clean Holdings filed its routine quarterly earnings 8-K on April 28, 2026, announcing first quarter 2026 financial results for the period ended March 27, 2026. The filing follows standard SEC practice: the 8-K body references the earnings announcement, while the actual financial metrics and management commentary are contained in the attached press release (Exhibit 99.1). This is a procedural disclosure with no unusual elements.

Retail investors should review the attached press release for revenue, earnings, guidance, and management's discussion of business conditions in the semiconductor equipment sector. As a follow-on, watch for the company's 10-Q filing in the coming weeks, which will provide detailed financial statements, risk factor updates, and management's discussion and analysis of the quarter's performance.
