Forward-Looking Statements

Certain statements in this communication may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including statements related to TTM’s future business outlook. Actual results may differ materially from these forward-looking statements. Such statements relate to a variety of matters, including but not limited to: the operations of the businesses of TTM Technologies, Inc. (“TTM” or the “Company”). These statements are made on the basis of the current beliefs, expectations and assumptions of the management of TTM regarding future events and are subject to significant risks and uncertainty. Statements regarding our expected performance in the future are forward-looking statements.

It is uncertain whether any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do, what impact they will have on the results of operations and financial condition of the Company. These forward-looking statements involve certain risks and uncertainties that could cause actual results to differ materially from those indicated in such forward-looking statements and are set forth in the Company’s most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q and in the

Company’s other filings filed with the Securities and Exchange Commission (the “SEC”) under the heading “Risk Factors” and which are available at the SEC’s website at www.sec.gov.

TTM does not undertake any obligation to update any of theses statements to reflect any new information, subsequent events or circumstances, or otherwise, except as may be required by law.

Use of Non-GAAP Financial Measures

In addition to the financial statements presented in accordance with U.S. GAAP, TTM uses certain non-GAAP financial measures, including “adjusted EBITDA.” The companies present non-GAAP financial information to enable investors to see each company through the eyes of management and to provide better insight into its ongoing financial performance.

Adjusted EBITDA is defined as earnings before interest expense, income taxes, depreciation, amortization of intangibles, stock-based compensation expense, gain on sale of assets, asset impairments, restructuring, costs related to acquisitions, and other charges. For a reconciliation of adjusted EBITDA to net income, please see the appendix at the end of this presentation. Adjusted EBITDA is not a recognized financial measure under U.S. GAAP and does not purport to be an alternative to operating income or an indicator of operating performance. Adjusted EBITDA is presented to enhance an understanding of operating results and is not intended to represent cash flows or results of operations. The use of this non-GAAP measure provides an indication of each company’s ability to service debt, and management considers it an appropriate measure to use because of the Company’s leveraged positions.

Adjusted EBITDA has certain material limitations, primarily due to the exclusion of certain amounts that are material to each Company’s consolidated results of operations, such as interest expense, income tax expense, and depreciation and amortization. In addition, adjusted EBITDA may differ from the adjusted EBITDA calculations reported by other companies in the industry, limiting its usefulness as a comparative measure.

Data Used in This Presentation

Due to rounding, numbers presented throughout this and other documents may not add up precisely to the totals provided and percentages may not precisely reflect the absolute figures.

Third Party Information

This presentation has been prepared by the Company and includes information from other sources believed by the Company to be reliable. No representation or warranty, express or implied, is made as to the fairness, accuracy or completeness of any of the opinions and conclusions set forth herein based on such information.
