FOR IMMEDIATE RELEASE

CTS Announces First Quarter 2026 Results

Strong Results driven by Growth in Diversified End‑Markets

Lisle, Ill. - CTS Corporation (NYSE: CTS), a leading global designer and manufacturer of highly engineered solutions that “Sense, Connect and Move,” today announced results for the first quarter of 2026.

“CTS delivered another quarter of strong performance, with diversified end‑market sales up 18% year over year and modest growth in transportation,” said Kieran O’Sullivan, CEO of CTS Corporation. “Our teams executed well, driving profitable growth, margin expansion, and strong cash generation. Diversification remains central to our strategy as we continue to strengthen our growth and quality of earnings.”

First Quarter 2026 Results

•

Sales were $139 million in the first quarter of 2026, up 11% year-over-year. Sales to diversified end markets increased 18%. Sales to the transportation market increased 3%.

•

Net income was $17 million, or 12.4% of sales, compared to $13 million, or 10.6% of sales in the first quarter of 2025.

•

Diluted EPS was $0.59, up 15 cents from $0.44 in the first quarter of 2025.

•

Adjusted Gross margin was 39.5%, up 250 bps from 37.0% in the first quarter of 2025.

•

Adjusted EBITDA margin was 23.0%, up 250 bps from 20.5% in the first quarter of 2025.

•

Adjusted diluted EPS was $0.62, up 18 cents from $0.44 in the first quarter of 2025.

•

Operating cash flow was $17.3 million, up $1.8 million from $15.5 million in the first quarter of 2025.

2026 Guidance

Assuming the continuation of current market conditions, CTS is narrowing its previous guidance of 2026 sales from a range of $550-$580 million to $560-$580 million and adjusted diluted EPS from a range of $2.30-$2.45 to $2.35-$2.45.

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.

OTHER SUPPLEMENTAL INFORMATION - UNAUDITED

(In millions of dollars, except percentages and per share amounts)

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 reduction costs, building and equipment relocation costs, asset impairment charges and other facility closure costs 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 US GAAP. These include duplicative expenses incurred due to the plant consolidation related transition activities such as excess rent, utilities, personnel related and other costs prior to start of production at the 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 and other 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.

(e) Reflected in Income tax expense. 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 and the tax impacts of an immaterial correction of a prior period error.

(f) 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.

NOTE: 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 (such as those items noted above in the paragraph titled “Non-GAAP Financial Measures”) or were not part of CTS’ business operations during a comparable period.

CTS Corporation 1st Quarter 2026 Earnings Call April 29, 2026

Cautionary Statement Regarding Forward-Looking Statements Readers are cautioned that the statements contained in this document regarding expectations of our performance or other matters that may affect our business, results of operations, or financial condition are, or may be deemed to be, “forward-looking statements” as defined by the “safe harbor” provisions in the Private Securities Litigation Reform Act of 1995. Such statements are made in reliance on the safe harbor provisions of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical fact, included or incorporated in this document, including statements regarding our strategy, financial position, guidance, funding for continued operations, cash reserves, liquidity, projected costs, plans, projects, awards and contracts, and objectives of management, among others, are forward-looking statements. Words such as “expect,” “anticipate,” “should,” “believe,” “hope,” “target,” “continued,” “project,” “plan,” “goals,” “opportunity,” “appeal,” “estimate,” “potential,” “predict,” “demonstrates,” “may,” “will,” “might,” “could,” “intend,” “shall,” “possible,” “would,” “approximately,” “likely,” “outlook,” “schedule,” “on track,” “poised,” “pipeline,” and variations of these terms or the negative of these terms and similar expressions are intended to identify these forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements are not guarantees of future performance, conditions or results. 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: supply chain disruptions (including, but not limited to, the availability and cost of rare earth elements, minerals and metals); changes in the economy generally, including inflationary and/or recessionary conditions and increased tariffs, and in respect to the businesses in which CTS operates; unanticipated issues in integrating acquisitions; the funding of contracts by the U.S. Government; 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; risks associated with CTS’ international operations, including trade and tariff barriers, exchange rates and political and geopolitical risks (including, without limitation, the impact of tariffs on China, Canada and Mexico, and other nations, the potential impact of U.S./China relations and the impact of geopolitical conflicts may have on our business, results of operations and financial condition; write offs of goodwill on our balance sheet; the amount and timing of any share repurchases; and the effect of any cybersecurity incidents on our business. Many of these, and other risks and uncertainties, are discussed in further detail in Item 1A. of CTS's 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. CTS refers to the forward-looking measures of book-to-bill ratio and total booked business in this document. Book-to-bill ratio is the ratio of customer orders received to revenues recorded for the same period. Although the book-to-bill ratio reflects firm customer orders, changes such as terminations, amendments, or contract cancellations may occur which could result in a reduction to the customer orders. Total booked business reflects expected revenue from the remaining life of long-term agreements with transportation customers. Total booked business is adjusted periodically for changes in expected revenue based on market information, fluctuations in foreign currency exchange rates, information from our customers, and any other factors that may impact the expected revenue from these agreements. Book-to-bill ratio and total booked business are not defined by U.S. GAAP and our methodology for calculating these measures may not be consistent with or comparable to other similarly titled measures of other companies.

Q & A

Appendix

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 incurred due to plant consolidation related transition activities such as excess rent, utilities, personnel related and other costs incurred prior to the start of production at the 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 and other 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.

Reflected in Income tax expense. 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 and the tax impacts of an immaterial correction of a prior period error. 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. Regulation G Schedules

($ 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.
