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 believes that the non-GAAP financial measures presented are commonly used by financial analysts and others in the industries in which CTS operates, and thus further provide useful information to investors. CTS' definitions of these non-GAAP financial measures may differ from those terms as defined or used by other companies. Non-GAAP measures should not be used by investors or third parties as the sole basis for formulating investment decisions, as they may exclude a number of important cash and non-cash recurring items. CTS has presented these non-GAAP financial measures as it believes that the presentation of its financial results that exclude (1) restructuring charges; (2) restructuring-related charges; (3) environmental charges; (4) acquisition-related adjustments; (5) inventory fair value step-up costs; (6) foreign exchange (gains) losses; (7) non-cash pension expenses (income); and (8) certain discrete tax items are useful and assist in comparing CTS' current operating results with past periods and with the operational performance of other companies in its industry. Included below is a description of the expenses that CTS has determined are not normal, recurring cash operating expenses necessary to operate its business and the rationale for why providing financial measures for its business with such expenses excluded or adjusted is useful to investors as a supplement to the U.S. GAAP measures. Restructuring charges – costs primarily relating to workforce reductions, building and equipment relocations, asset impairment charges and other facility closure activities in connection with our continued optimization of our organization. Restructuring-related charges – costs related to restructuring actions that do not qualify as direct restructuring charges under U.S. GAAP. These include duplicative expenses arising from plant consolidation transition activities such as excess rent, utilities, personnel-related and other costs incurred prior to the start of production at a new location. Environmental charges – costs associated with our non-operating facilities that are unrelated to ongoing operations. Currently, none of these costs and accruals relate to sites that provide revenue generating activities for the Company. Acquisition-related adjustments – diligence and transaction costs related to acquisitions including related contingent earnout adjustments. Inventory fair value step-up costs – purchase accounting-related inventory costs from acquisitions. Foreign exchange (gains) losses – remeasurement income and expenses for non-U.S. subsidiaries with the U.S. dollar as the functional currency. Non-cash pension expenses (income) – pension income and expenses relating to the non-operating U.S. pension and post-retirement life insurance plans, including historical plan settlement activities. Discrete tax items – non-recurring, infrequent, or unusual tax adjustments (e.g., valuation allowances, uncertain tax position changes, unremitted assertion changes and discrete impacts associated with pre-tax non-GAAP items or due to tax law changes, etc.). At times, the reconciliations below have been intentionally rounded to the nearest thousand, or $0.01 for EPS figures, and, therefore, may not sum. 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. The Company updated certain previously furnished 2024 amounts due to immaterial errors identified. Refer to Note 1, "Basis of Presentation" in the Quarterly Report on Form 10-Q as of September 30, 2025 for more information.

Reflected in selling, general and administrative and other (expense) income, net. Reflected in cost of goods sold. Reflected in restructuring charges. Reflected in other (expense) income, net. Reflected in income tax expense (income). For 2022, the discrete tax items relate to the net impact to tax expense of expired research and development credits, including the release of associated reserves. For 2023, discrete tax items include adjusting for tax benefits resulting from $0.6 million for research and development tax credits from prior years, $0.8 million in foreign tax credits related to prior years from a 2023 tax law change, as well as $0.2 million from the release of uncertain tax benefits. For 2024, the discrete tax items relate to items we deemed outside normal cash-generating operations including the addition of a valuation allowance for a foreign subsidiary. For 2025, the discrete tax items relate to items we deemed outside normal cash-generating operations including the addition of a valuation allowance for research and developmental credits, the tax impacts of an immaterial correction of a prior period error, the tax impacts related to cost associated with the environmental contamination liability. We determine the tax effect of non-GAAP adjustments by considering the tax laws and statutory income tax rates applicable in the tax jurisdictions of the underlying non-GAAP adjustments. For all periods presented, we applied the statutory income tax rates to the taxable portion of all of our adjustments. Our acquisition costs and foreign currency gains and losses included in our non-GAAP adjustments were not deductible for income tax purposes; therefore, no statutory income tax rate was applied to such costs.

($ Millions, except percentages) Free Cash Flow ($ Millions, except percentages) Controllable Working Capital NOTE: CTS believes the controllable working capital ratio is a useful measure because it provides an objective measure of the efficiency with which CTS manages its short-term capital needs. NOTE: CTS believes that free cash flow is a useful measure because it demonstrates the company's ability to generate cash. Free cash flow is a non-GAAP measure and should be considered in addition to, but not as a substitute for, information contained in the company's condensed consolidated statement of cash flows as a measure of liquidity.
