Cautionary Statement Regarding Forward-Looking Statements

From time to time, we make written or oral “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended, including statements contained in our filings with the Securities and Exchange Commission (the “SEC”) (including this Report for the year ended December 31, 2025), in our annual report to stockholders and in other communications. These statements do not convey historical information, but relate to predicted or potential future events, such as statements of our plans, strategies and intentions, or our future performance or goals, projections of revenue, taxable earnings (loss), net earnings (loss), net earnings (loss) per share, capital expenditures and other financial items, that are based on management’s current expectations and estimates. Our forward-looking statements can often be identified by the use of forward-looking terminology such as “aim,” “believe,” “expect,” “intend,” “may,” “could,” “continue,” “will,” “should,” “plans,” “depending,” “projects,” “forecasts,” “focus,” “seeks,” “anticipates,” “goal,” “objective,” “target,” “estimates,” “future,” “strategy,” “vision,” or variations of such words or similar terminology. Investors and prospective investors are cautioned that such forward-looking statements are only projections based on current expectations and estimates. These statements involve risks and uncertainties and are based upon various assumptions. Such risks and uncertainties include, but are not limited to:

•our ability to execute on our VISION 2030 Strategy;

•our ability to grow our presence in the Auto/Electric Vehicle (“EV”), Defense/Aerospace, Industrial, Life Sciences, Safety/Security and international markets;

•our ability to convert backlog to sales and to ship product in a timely manner;

•the loss of any one or more of our largest customers, or a reduction in orders by a major customer;

•our ability to meet the terms and covenants related to our credit facility;

•changes in the rate of, and timing of, capital expenditures by our customers;

•the availability of and retention of key personnel or our ability to hire personnel at anticipated costs; and

•changes in U.S. and/or foreign trade policy and/or general economic conditions both domestically and globally.

We discuss many of these risks and uncertainties and others under “Part I; Item 1A. Risk Factors,” in this Report, and elsewhere in this Report. These risks and uncertainties, among others, could cause our actual future results to differ materially from those described in our forward-looking statements or from our prior results. Any forward-looking statement made by us in this Report is based only on information currently available to us and speaks to circumstances only as of the date on which it is made. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Report to conform these statements to actual results or to changes in our expectations, except as required by law.
