Use of Non-GAAP Measures

This release and the accompanying tables include a discussion of Pro Forma Adjusted EBITDA for UCT and Ham-Let, which is a non-GAAP financial measure that is provided as a complement to results provided in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We define “Adjusted EBITDA” as net income (loss) plus provision for (benefit from) taxes, interest and other expense (income), depreciation expense, amortization expense, stock-based compensation expense, restructuring charges and other infrequent or unusual items.

Non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. In addition, the definition of Adjusted EBITDA used in this press release may not be comparable to the definitions as reported by other companies.

We believe Adjusted EBITDA is relevant and useful information because it provides UCT and investors with additional measurements to analyze past operating performance and enterprise value. The unaudited Pro Forma Adjusted EBITDA financial information is not necessarily indicative of the results of income in future periods or the results that actually would have been realized had UCT and Ham-Let been a combined company during the specified period.

A reconciliation of Net income to pro forma-adjusted EBITDA is provided in the accompanying table.
