Any statements that are not statements of historical fact, including statements containing the words “believes,” “intends”, “continues,” “reflects,” “plans,” “anticipates,” “expects,” and similar expressions, should also be considered to be forward-looking statements. Readers should not place undue reliance on these forward-looking statements, which are based upon management’s current beliefs and expectations. These forward-looking statements are subject to risks and uncertainties, and actual results might differ materially from those discussed in, or implied by, the forward-looking statements. Among the risks and uncertainties that could cause actual results or events to differ materially from those indicated by such forward-looking statements include, but are not limited to changing customer preferences; lack of success of new products; loss of customers; cybersecurity breaches; changes in competition in our markets; and increased prices for raw materials resulting from tariffs on imported goods or otherwise; and the inability to realize expected cost savings and synergies from the acquisition of Big 3 Precision in amounts or in the timeframe anticipated; the inability to retain customers and qualified employees of Big 3 Precision; the diversion of management’s time on issues relating to the acquisition and/or integration of Big 3 Precision; and greater than expected integration costs or difficulties may arise in connection with the acquisition of Big 3 Precision. There are important, additional factors that could cause actual results or events to differ materially from those indicated by such forward-looking statements, including those set forth in our reports and filings with the Securities and Exchange Commission.

Non-GAAP Measures This presentation includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) such as Adjusted EBITDA and certain ratios and other metrics derived there from. Adjusted EBITDA is net income before interest, taxes, depreciation and amortization and non-recurring costs and expenses. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that the presentation of these measures may not be comparable to similarly-titled measures used by other companies. We believe (i) these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends; and (ii) that the use of these non GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures.
