Use of Non-GAAP Measures
In addition to providing results that are determined in accordance with Generally Accepted Accounting Principles in the United States of America (“GAAP”), management uses non-GAAP gross margin, non-GAAP operating margin and non-GAAP net income to evaluate the Company’s operating and financial results. We believe the presentation of non-GAAP results is useful to investors for analyzing our core business and business trends and comparing performance to prior periods, along with enhancing investors’ ability to view the Company’s results from management’s perspective. The presentation of this additional information should not be considered a substitute for results prepared in accordance with GAAP. Tables presenting reconciliations from GAAP results to non-GAAP results are included at the end of this press release.

The Company defines non-GAAP net income as net loss before amortization of intangible assets, stock-based compensation, restructuring charges, debt refinancing costs, legal-related costs, unrealized loss (gain) on foreign exchange, VAT settlement, and the tax effects of the foregoing adjustments.

A reconciliation of our guidance for non-GAAP net income per diluted share for the subsequent quarter is not available due to fluctuations in the geographic mix of our earnings from quarter to quarter, which impacts our tax rate and cannot be reasonably predicted or determined. As a result, such reconciliation is not available without unreasonable efforts and we are unable to determine the probable significance of the unavailable information.

Safe Harbor Statement
The foregoing information contains, or may be deemed to contain, “forward-looking statements” (as defined in the US Private Securities Litigation Reform Act of 1995) which reflect our current views with respect to future events and financial performance. We use words such as “anticipates,” “projection,” “outlook,” “forecast,” “believes,” “plan,” “expect,” “future,” “intends,” “may,” “will,” “estimates,” “see,” “predicts,” “should” and similar expressions to identify these forward-looking statements. Forward looking statements included in this press release include our expectations about the semiconductor capital equipment market and outlook. All forward-looking statements address matters that involve risks and uncertainties. Accordingly, the Company’s actual results may differ materially from the results predicted or implied by these forward-looking statements. These risks, uncertainties and other factors also include, among others, those identified in “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in our annual report on Form 10-K for the year ended December 26, 2025, as filed with the Securities and Exchange Commission. Ultra Clean Holdings, Inc. undertakes no obligation to publicly update or review any forward-looking statements, whether as a result of new information, future developments or otherwise unless required by law.

9 The Company’s GAAP tax expense is generally higher than the Company’s non-GAAP tax expense, primarily due to losses in the U.S. with full federal and state valuation allowances. The Company’s non-GAAP tax rate and resulting non-GAAP tax expense considers the tax implications as if there was no federal or state valuation allowance position in effect
10 Non-GAAP diluted weighted-average common shares are adjusted to reflect the dilutive impact of our convertible note based on the capped call cap price instead of the initial conversion price
