CTS Announces First Quarter 2023 Results

Solid Quarter, Managing Through Challenging Market Dynamics

Lisle, Ill. - CTS Corporation (NYSE: CTS), a leading global designer and manufacturer of custom engineered solutions that “Sense, Connect and Move,” today announced first quarter 2023 results.

“We delivered solid results in the first quarter, supported by ongoing execution of our diversification strategy, against a backdrop of persistent macroeconomic headwinds. Market conditions remain challenging. We are continuing to capture new business to expand into premium non-transportation end markets while gaining momentum on winning new electrification business.” said Kieran O’Sullivan, CEO of CTS Corporation. “With a strong financial profile and robust balance sheet, we are well-positioned to continue driving progress on our strategic priorities to deliver long-term profitable growth and stakeholder value.”

First Quarter 2023 Results

2023 Guidance

CTS is maintaining its guidance of sales in the range of $580 - $640 million and adjusted diluted EPS to be in the range of $2.40 - $2.70. Management continues to carefully monitor the potential impact of uncertain macroeconomic and geopolitical conditions.

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.

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) environmental charges; (3) acquisition-related costs; (4) inventory fair value step-up costs; (5) foreign exchange (gains) losses; (6) non-cash pension expenses (income); and (7) 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.

At times, the reconciliations below have been intentionally rounded to the nearest thousand, or $0.01 for EPS figures, and, therefore, may not sum.

Adjusted Gross Margin

Adjusted Operating Earnings

Adjusted EBITDA Margin

Adjusted Net Earnings

(a) reflected in selling, general and administrative expenses.
(b) reflected in cost of goods sold.
(c) reflected in restructuring charges.

(d) reflected in other (expense) income, net.

(e) reflected in income tax expense (income).

Adjusted Diluted Earnings Per Share

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.

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.

Free Cash Flow

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.

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) environmental charges; (3) acquisition-related costs; (4) inventory fair value step-up costs; (5) foreign exchange (gains) losses; (6) non-cash pension expenses (income); and (7) 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. • Environmental charges - costs associated with our non-operating facilities that are unrelated to ongoing operations. • Acquisition-related costs - diligence and transaction costs related to acquisitions. • 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 its 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, 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.
