Statements contained in this Quarterly Report on Form 10-Q (this “Form 10-Q”) that reflect our current views with respect to future events and financial performance, business strategies, expectations for our business and any other statements of a future or forward-looking nature, constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

These forward-looking statements include, but are not limited to, statements about our financial condition, results of operations, earnings outlook and prospects or regarding our or our management’s expectations, beliefs, intentions or strategies regarding the future, including our expectations regarding our revenues, cost of revenues, operating expenses, other operating results, and other key metrics, and our ability to meet previously announced earnings guidance with respect to the Company and/or its individual segments. These forward-looking statements involve risks and uncertainties that could cause our actual results to differ materially from those contemplated in the forward-looking statements, including, without limitation, the risks set forth in Part II, Item 1A, “Risk Factors” in this Form 10-Q and in our other filings with the Securities and Exchange Commission (the “SEC”). We do not assume any obligation to update any forward-looking statements after the date of this Form 10-Q, except as required by law.

In addition, any statements that refer to projections, forecasts, or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements are typically identified by words such as “plan,” “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “would”, “will” and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking.

The forward-looking statements contained in this Form 10-Q are based on our current expectations and beliefs concerning future developments and their potential effects on us. We cannot assure you that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control), or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. Some factors that could cause actual results to differ include, but are not limited to:

•changes adversely affecting the business in which we are engaged;

•geopolitical risks and changes in applicable laws or regulations;

•operational risk;

•the inability to realize expected benefits and efficiencies from our cost-savings initiatives and restructuring plans;

•any failure to effectively manage, and receive anticipated returns from, acquisitions, divestitures, investments, joint ventures and other portfolio actions;

•fluctuations in the demand for our products and services;

•the impact of supply chain disruptions, tariffs, trade restrictions, and inflation and our ability to recoup rising costs in the rates we charge to our customers;

•our ability to recoup refunds from invalidated tariffs;

•the possibility that our long-lived assets and other assets, including inventory, property, plant, equipment, intangibles, and investments in unconsolidated affiliates may become impaired;

•our ability to maintain the listing of our securities on a national securities exchange;

•the possibility of significant changes in foreign exchange rates and controls;

•litigation and regulatory enforcement risks, including the diversion of management’s time and attention and the additional costs and demands on our resources;

•general economic conditions, including the capital and credit markets, and adverse macroeconomic conditions, including unemployment, inflation, fluctuating interest rates, changes in consumer practices due to slower economic growth, and regional or global liquidity constraints;

•the possibility of political instability, war, or acts of terrorism in any of the countries where we operate; and

•other risks and uncertainties described from time to time in our filings with the SEC, press releases, and other communications, including those set forth under “Risk Factors” included in our Annual Report on Form 10-K for the year ended January 3, 2026, and in the documents incorporated by reference herein and therein.

All subsequent written and oral forward-looking statements concerning the matters addressed in this Form 10-Q and attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this Form 10-Q. Except to the extent required by applicable law or regulation, we undertake no obligation to update these forward-looking statements to reflect events or circumstances after the date of this Form 10-Q or to reflect the occurrence of unanticipated events.
