Ultra Clean Holdings, Inc. Files Amendment to Quarterly Report: New Insider Trading Plans Disclosed

Ultra Clean Holdings, Inc. (NASDAQ: UCTT) has filed an Amendment No. 1 on Form 10-Q/A with the U.S. Securities and Exchange Commission (SEC) for the fiscal quarter ended March 27, 2026. This amendment adds critical new disclosures regarding insider trading arrangements by senior executives, a point of significant interest for shareholders and potential investors.

Key Highlights from the Amended Filing

• Purpose of the Amendment: The document was filed to revise Part II, Item 5 (“Other Information”) of the original 10-Q by disclosing Rule 10b5-1 trading plans that were inadvertently omitted previously. These plans were adopted by the Chief Financial Officer, Sheri Savage, and the Chief Accounting Officer, Brian Harding, during the reported quarter. The company affirms that no other sections or financial statements have been changed.
• New Insider Trading Arrangements:
  • Sheri Savage, Chief Financial Officer: Entered into a Rule 10b5-1 trading plan on March 5, 2026, allowing the sale of up to 74,392 shares of common stock at or above certain minimum price thresholds. The plan is scheduled to terminate on May 31, 2027, subject to early termination.
  • Brian Harding, Chief Accounting Officer: Entered into a similar Rule 10b5-1 plan on March 5, 2026, for the sale of up to 38,207 shares of common stock, also subject to minimum price thresholds. This plan is set to expire on June 4, 2027, unless terminated sooner.
• Regulatory Compliance: The amendment includes new certifications by the company’s principal executive officer and principal financial officer, as required by Rule 12b-15 under the Securities Exchange Act. These certifications affirm the accuracy of the report and its compliance with Section 302 of the Sarbanes-Oxley Act.
• No Financial Statement Changes: The amendment does not alter or restate any financial statements or impact previously reported financial results. It is solely to update disclosure of the trading arrangements.

Potential Impact on Shareholders and Share Price

• Insider Trading Plans—Price Sensitivity: The disclosure of new Rule 10b5-1 trading arrangements by senior financial officers is a material development. Rule 10b5-1 plans allow insiders to sell shares based on a pre-arranged schedule, provided certain conditions are met. The planned sales by the CFO and CAO involve substantial share volumes and could draw market attention:
  • CFO Plan: Up to 74,392 shares (approx. 0.17% of outstanding shares as of April 2026)
  • CAO Plan: Up to 38,207 shares

  While these sales are structured to comply with SEC rules and avoid the appearance of trading on material non-public information, any significant insider sales could be interpreted by the market as a lack of confidence in the near-term share price or company prospects, and may exert downward pressure on the stock. However, such plans are also often used for personal financial planning and diversification.

• No Restatement or Financial Impact: The company makes it clear that no financial statements are being amended, and the omission corrected was solely related to disclosure. There has been no adverse finding, restatement, or error in the company’s financial reporting.
• Ongoing Regulatory Compliance: The company remains current with its SEC filing requirements and has submitted all required interactive data files. This signals ongoing transparency and regulatory compliance.

Other Notable Details

• Shares Outstanding: As of April 2026, there were 44,828,352 shares of common stock outstanding.
• Certifications Filed: Certifications by the CEO (James Xiao) and CFO (Sheri Savage) are attached, affirming the accuracy and completeness of the amended report.
• Trading Venue: The company’s common stock trades on The Nasdaq Stock Market under the symbol UCTT.

Conclusion

The most significant new information for investors is the disclosure of substantial insider trading plans by the CFO and CAO. While the plans are compliant with SEC rules, investors should monitor any subsequent insider sales and assess potential impacts on market sentiment and stock liquidity. There are no changes to the company’s financial statements or restatements to report.
