FOR RELEASE: Immediately

CTS FINISHES 2004 WITH STRONG FOURTH QUARTER
ACHIEVES DOUBLE DIGIT SALES AND EARNINGS GROWTH FOR THE YEAR

Elkhart, IN...CTS Corporation (NYSE:CTS) today announced fourth quarter revenues of $142.5 million, up $13.4 million, or 10%, over the third quarter of 2004. On a year-over-year basis, fourth quarter revenues were up 8%. The strong fourth quarter represented the best quarterly sales results since the second quarter of 2001.

Net earnings for the fourth quarter were $6.6 million, or $0.17 per share diluted, and included a $0.01 per share reduction due to the adoption of the new accounting rules for contingently convertible debt. This compares to $3.9 million in net earnings or $0.11 per share diluted in the fourth quarter of 2003.

Full-year 2004 revenues of $531.3 million exceeded 2003 revenues by $68.3 million or 15%. Full-year 2004 net earnings of $20.0 million, or $0.53 per share, substantially exceeded 2003 earnings of $12.6 million, or $0.36 per share.

2004 diluted earnings per share include a gain of approximately $0.06 on the sale of excess land in Canada, partially offset by a reduction of $0.02 per share as required by the new accounting rules on contingently convertible debt. Included in 2003 results were a favorable income tax adjustment of $0.22 per share, and an asset impairment charge of $0.10 per share.

Commenting on the fourth quarter, Donald Schwanz, CTS Chairman and Chief Executive Officer, said, “Our financial results reflect solid sales growth, particularly in our automotive products and electronics manufacturing services, as well as our continued focus on margin enhancement. Business wins for recently introduced products and awards from new customers continued the strong positive trends of the past several quarters.”

During the fourth quarter, CTS announced an agreement to acquire SMTEK, a publicly traded company in the electronics manufacturing services industry. Closing on this acquisition is expected shortly. The acquisition of SMTEK is expected to be accretive in 2005 to CTS results by $0.04 to $0.06 per share.

Including the impact of the SMTEK acquisition, management currently expects full-year 2005 sales to increase 30% to 35% over 2004 and diluted earnings per share to be in the range of $0.65 to $0.72. Earnings per share guidance reflects a $0.05 per share reduction for adopting new accounting rules for contingently convertible debt and a reduction of $0.02 related to accounting for expensing of stock options beginning July 2005.

General Comments:

•   During 2004, the Company generated free cash flow, defined as operating cash flow less cash flow from investing activities, of $21.1 million, compared to $20.6 million in 2003.

•   Total debt net of cash ended the year at $36.5 million, $14.0 million lower than year-end 2003. Total debt to capitalization ratio was 24% at year-end, well within the Company’s target range of 20% to 30%.

•   Cash balances at the end of 2004 were $61.0 million, up $35.7 million from the end of 2003.

•   Capital expenditures of $12.7 million, or 2.4% of sales in 2004 compare to $9.0 million, or 2.0% of sales in 2003.

			Segment				Segment				Segment
	Net		Operating		Net		Operating		Net		Operating
	Sales		Earnings		Sales		Earnings		Sales		Earnings
Components & Sensors	$	66.0	$	6.9	$	67.1	$	3.8	$	63.2	$	4.6

Total	$	142.5	$	9.7	$	132.0	$	7.4		129.0	$	5.9

Components & Sensors: Components and sensors sales decreased by $1.1 million, or 2%, from the fourth quarter of 2003, reflecting declining component sales into mobile handset applications, partially offset by growth in automotive product sales. Segment sales increased by $2.8 million, or 4% over the third quarter of 2004, primarily from improved automotive product demand as normal summer shutdowns at OEMs ended. Segment operating earnings increased over both fourth quarter last year and the third quarter of 2004 as a result of improved volume, favorable product mix, Singapore factory allocations to the EMS segment, cost reductions and increased efficiencies across all product lines.

EMS: EMS fourth quarter sales increased by $11.6 million, or 18%, from the fourth quarter of last year, driven primarily by increased demand for communications infrastructure and computer data storage equipment. However, segment operating earnings were lower than the fourth quarter of 2003, primarily due to unfavorable currency exchange, Singapore factory cost allocations between segments, product mix, and pricing. The fourth quarter 2004 EMS sales rose by $10.7 million, or 16%, over third quarter 2004, due to higher computer end-market demand for high-end storage systems and strong demand for communications infrastructure products. The impact of the higher sales improved the level of segment operating earnings.

Free cash flow is a non-GAAP financial measure which CTS defines as net cash provided by operations plus net cash provided by (used in) investing activities. The most directly comparable GAAP financial measure is net cash provided by operations. Management believes that free cash flow provides useful information to investors regarding the Company’s ability to generate cash from business operations that is available for internal growth, service of debt principal, dividends, share repurchase and acquisitions and other investments. Management uses free cash flow as one measure to monitor and evaluate the performance of the Company.
