CTS Announces Agreement to Sell its Low Temperature Cofired Ceramics Operation to American Technical Ceramics Corp.

ELKHART, Ind.--Sept. 14, 2005--CTS Corporation today announced that it has entered into an asset purchase agreement with American Technical Ceramics Corp. (ATC) for the sale of the assets of its Low Temperature Cofired Ceramic (LTCC) product operations. The sale includes production equipment and inventory associated with the LTCC product line, but excludes the West Lafayette, Indiana facility where LTCC product operations have been conducted.

Under the terms of the agreement CTS will continue LTCC operations over the next few months, while ATC prepares to transfer the equipment to its facility. During this transition, CTS expects to continue to meet all customer requirements.

Tyler Buchanan, CTS senior vice president, stated, "The Low Temperature Cofired Ceramics operation is not strategic to our company. Annual sales are less than $8 million per year, with profitability near break-even. Therefore, the sale will have little impact on total company results, while freeing management time to focus on growth areas of the business."

The transaction is not expected to have a material impact on 2005 results. Once the transfer of equipment to ATC is completed, the Company expects to sell the West Lafayette, Indiana facility.
