CTS ANNOUNCES FIRST QUARTER 2015 RESULTS

1Q 2015 Earnings on Track; Strong New Business Awards;

Expands Share Buyback Program

Elkhart, IN. CTS Corporation (NYSE: CTS) announced 1st quarter 2015 results.

·                  Sales were $98.3 million, down 2.4% compared to the first quarter of 2014, driven primarily by an unfavorable currency impact of $2.3 million as the US Dollar appreciated against the Euro and Chinese Renminbi.

·                  GAAP earnings were $6.3 million, or $0.19 per diluted share, compared to $5.1 million, or $0.15 per diluted share from continuing operations in the first quarter of 2014.

·                  Adjusted EPS was $0.20, compared to $0.19 in the first quarter of 2014.

·                  Currency impacted net earnings unfavorably by $1.7 million due to balance sheet translation of assets denominated in European currencies.

First quarter sales to automotive customers declined $3.7 million year-over-year primarily due to unfavorable currency impact of $2.3 million. Sales of electronic components increased $1.3 million year-over-year. CTS received $192 million in new business awards in the first quarter.

“We continued to execute well in the first quarter of 2015 although currency impacted our top line and earnings unfavorably,” said Kieran O’Sullivan, CEO of CTS Corporation. “We recorded our strongest new business awards since we began reporting in the second quarter of 2013. We are following our strategic plan and transitioning our focus to Sense | Connect | Move.”

CTS is expanding its share buyback program by $25 million. Including the remaining portion of the previous authorization, the total program has increased to approximately $32 million.

2015 Guidance

Management reaffirms its guidance for full year 2015 sales in the range of $400 to $430 million and adjusted earnings per diluted share in the range of $0.98 to $1.10. Currency continues to be a concern and may unfavorably impact Management’s guidance by 2-3% on sales and 5-8 cents on earnings.

Non-GAAP Financial Measures

Adjusted earnings per share is a non-GAAP financial measure.  The most directly comparable GAAP financial measure is diluted earnings per share.

CTS adjusts for these items because they are discrete events which have a significant impact on comparable GAAP financial measures and could distort an evaluation of our normal operating performance.

CTS uses an adjusted earnings per share measure to evaluate overall performance, establish plans and perform strategic analysis.  Using this measure avoids distortion in the evaluation of operating results by eliminating the impact of events which are not related to normal operating performance.  Because this measure is based on the exclusion or inclusion of specific items, they may not be comparable to measures used by other companies which have similar titles.  CTS’ management compensates for this limitation when performing peer comparisons by evaluating both GAAP and non-GAAP financial measures reported by peer companies.  CTS believes that this measure is useful to its management, investors and stakeholders in that it:

· provides a meaningful measure of CTS’ operating performance,

· reflects the results used by management in making decisions about the business, and

· helps review and project CTS’ performance over time.

We recommend that investors consider both actual and adjusted measures in evaluating the performance of CTS with peer companies.
