The CTS Story 1896 2015 1902 1922 1950 1962 1980’s 1999 2012 2013 Chicago Telephone Supply Company established (later to become CTS) Evolved from a manufacturer of finished products (telephones and switchboards) to a major supplier of radio receiver components Listed on the “Big Board” at the New York Stock Exchange Purchased Component Products Division (CPD) of Motorola, including RF Filter and Piezoelectric technology. Entered emerging cell phone handset and base station market, Acquired D&R Technology. Expanded strategic automotive sensor product platform with new customers and a broader product portfolio In need of more space, the Company moved to Elkhart, Indiana, about 100 miles east of Chicago When television fever hit America, the Company applied its radio technology to the new television market Automotive emissions control requirements pushed CTS into custom under-the-hood and chassis position sensor business Sold EMS business as part of its strategy to simplify, focus and drive profitable growth CTS Corporation – More than 100 years of innovation 1964 Acquired James Knight & Co. Became major supplier of quartz crystal producing oscillation in frequency control devices 1967 Established plants in Taiwan, Mexico to increase cost efficiency, penetrate international markets 3 Acquired Filter Sensing Technologies. Innovative sensing technology with potential to become a sensing platform
