Safe Harbor Statement Safe Harbor Statement Certain statements contained in this presentation contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements may be identified by the use of forward-looking words or phrases such as “anticipate,” “believe,” “could,” “expect,” “intend,” “may,” “planned,” “potential,” “should,” “will,” and “would.” Such forward-looking statements are inherently subject to many uncertainties in the Company’s operations and business environment. These uncertainties include general economic conditions, in particular, relating to the automotive industry, consumer demand for the Company’s and its customers’ products, competitive and technological developments, customer purchasing actions, changes in warranty provisions and customer product recall policies, work stoppages at the Company or at the location of its key customers as a result of labor disputes, foreign currency fluctuations, the impact of U.S. trade policies, tariffs and reactions to the same from foreign countries on costs and customer demand, matters adversely impacting the timing and availability of component parts and raw materials needed for the production of our products and the products of our customers and fluctuations in our costs of operation. Shareholders, potential investors and other readers are urged to consider these factors carefully in evaluating the forward-looking statements and are cautioned not to place undue reliance on such forward-looking statements. The forward-looking statements made herein are only made as of the date of this press presentation and the Company undertakes no obligation to publicly update such forward-looking statements to reflect subsequent events or circumstances occurring after the date of this presentation. In addition, such uncertainties and other operational matters are discussed further in the Company’s quarterly and annual filings with the Securities and Exchange Commission. Use of Non-GAAP Financial Metrics and Additional Financial Information In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, STRATTEC provides Adjusted Non-GAAP information as additional information for its operating results. References to Adjusted Non-GAAP information are to non-GAAP financial measures.  These measures are not required by, in accordance with, or an alternative for, GAAP and may be different from similarly titled non-GAAP financial measures used by other companies. STRATTEC’s management uses these measures to make strategic decisions, establish budget plans and forecasts, identify trends affecting STRATTEC’s business, and evaluate performance. Management believes that providing these non-GAAP financial measures to investors, as a supplement to GAAP financial measures, will help investors evaluate STRATTEC’s core operating and financial performance and business trends consistent with how management evaluates such performance and trends.  Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures. The Company has provided reconciliations of comparable GAAP to non-GAAP measures in the supplemental slides of this presentation.
