CTS Investor Presentation Oct 2022

Forward-Looking Statements This document contains statements that are, or may be deemed to be, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, any financial or other guidance, statements that reflect our current expectations concerning future results and events, and any other statements that are not based solely on historical fact. Forward-looking statements are based on management’s expectations, certain assumptions and currently available information. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof and are based on various assumptions as to future events, the occurrence of which necessarily are subject to uncertainties. These forward-looking statements are made subject to certain risks, uncertainties and other factors, which could cause CTS’ actual results, performance or achievements to differ materially from those presented in the forward-looking statements. Examples of factors that may affect future operating results and financial condition include, but are not limited to: the ultimate impact of the COVID-19 pandemic on CTS’ business, results of operations or financial condition, including supply chain disruption; changes in the economy generally, including inflationary and/or recessionary conditions, and in respect to the business in which CTS operates; unanticipated issues in integrating acquisitions, including TEWA Temperature Sensors and Ferroperm Piezoceramics; the results of actions to reposition CTS’ business; rapid technological change; general market conditions in the transportation, as well as conditions in the industrial, aerospace and defense, and medical markets; reliance on key customers; unanticipated public health crises, natural disasters or other events; environmental compliance and remediation expenses; the ability to protect CTS’ intellectual property; pricing pressures and demand for CTS’ products; and risks associated with CTS’ international operations, including trade and tariff barriers, exchange rates and political and geopolitical risks (including, without limitation, the potential impact U.S./China relations and the conflict between Russia and Ukraine may have on our business, results of operations and financial condition). Many of these, and other risks and uncertainties, are discussed in further detail in Item 1A. of CTS’ most recent Annual Report on Form 10-K and other filings made with the SEC. CTS undertakes no obligation to publicly update CTS’ forward-looking statements to reflect new information or events or circumstances that arise after the date hereof, including market or industry changes. Non-GAAP Financial Measures From time to time, CTS may use non-GAAP financial measures in discussing CTS’ business. These measures are intended to supplement, not replace, CTS’ presentation of its financial results in accordance with U.S. GAAP. CTS’ management believes that non-GAAP financial measures can be useful to investors in analyzing CTS’ financial performance and results of operations over time. CTS recommends that investors consider both actual and adjusted measures in evaluating the performance of CTS with peer companies. The information included in this presentation includes the non-GAAP financial measures of adjusted gross margin, adjusted operating earnings, adjusted EBITDA margin, adjusted net earnings, adjusted diluted earnings per share, debt to capitalization ratio, controllable working capital ratio, and free cash flow. Many of these non-GAAP financial measures exclude the effect of certain expenses and income not related directly to the underlying performance of CTS’ fundamental business operations. CTS believes that adjusted gross margin, adjusted operating earnings, adjusted EBITDA margin, adjusted net earnings and, adjusted diluted earnings per share provide useful information to investors regarding its operational performance because they enhance an investor’s overall understanding of CTS’ core financial performance and facilitate comparisons to historical results of operations, by excluding items that are not related directly to the underlying performance of CTS’ fundamental business operations or were not part of CTS’ business operations during a comparable period. CTS believes that debt to capitalization ratio is a measurement of financial leverage and provides an insight into the financial structure of CTS and its financial strength. CTS believes the controllable working capital ratio provides an objective measure of the efficiency with which CTS manages its short-term capital needs.  CTS believes that free cash flow is a useful measure of its ability to generate cash. CTS believes that these non-GAAP financial measures are commonly used by financial analysts and others in the industries in which CTS operates, and thus further provide useful information to investors. Note that CTS’ definitions of these non-GAAP financial measures may differ from those terms as defined or used by other companies. CTS does not provide reconciliations of forward-looking non-GAAP financial measures, such as estimated adjusted diluted earnings per share, to the most comparable GAAP financial measures on a forward-looking basis because CTS is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of certain items, such as, but not limited to, restructuring costs, environmental remediation costs, acquisition related costs, foreign exchange rates and other non-routine costs. Each of such adjustments has not yet occurred, are out of CTS' control and/or cannot be reasonably predicted. For the same reasons, CTS is unable to address the probable significance of the unavailable information.
