(AMETEK LETTERHEAD) Contact: William J. Burke (610) 889-5249 AMETEK ACQUIRES TAYLOR HOBSON HOLDINGS LIMITED ACQUISITION EXPANDS AMETEK'S HIGH-END ANALYTICAL INSTRUMENT PLATFORM Paoli, PA, June 21, 2004 -- AMETEK, Inc. (NYSE: AME) today announced the acquisition of Taylor Hobson Holdings Limited (`Taylor Hobson'), a leading manufacturer of ultra-precision measurement instrumentation for a variety of markets, including optics, semiconductors, hard disk drives and nanotechnology research. Taylor Hobson was acquired from funds advised by Permira for a purchase price of approximately 51 million British pound sterling. With its headquarters in Leicester, England, Taylor Hobson has expected 2004 sales of approximately 38 million British pound sterling. "We are very excited about our acquisition of Taylor Hobson," comments AMETEK Chairman and Chief Executive Officer Frank S. Hermance. "This is a highly differentiated business, focusing on the most complex and critical measurements for its customers. Taylor Hobson significantly expands our measurement capabilities into ultra-precision applications and is an excellent fit with our strategic focus on adding more high-end analytical instrument businesses. With this acquisition, our high-end analytical businesses now total more than $250 million in annual revenue." "Taylor Hobson's instrumentation is able to measure the shape and finish of surfaces to the sub-nanometer level. This measurement capability is a critical enabling technology to support product development, manufacturing process engineering and quality control. As product geometries continue to shrink, Taylor Hobson's instrumentation becomes even more important," adds Mr. Hermance. Taylor Hobson designs, manufactures, and services a broad array of contact and non-contact instrumentation for ultra-precise measurement applications. These instruments measure surface texture, shape and roundness, dimensions that are critical in many industries including optics, semiconductor, hard disk drive, automotive and bearing manufacturing. Nanotechnology is becoming an increasingly important market for Taylor Hobson's technology and represents AMETEK's first entry into this exciting area. Taylor Hobson has long been a technology leader by providing standard setting ultra-precision contact measurement systems. More recently, Taylor Hobson has introduced new products based on non-contact optical technology, including the Coherence Correlation Interferometer (CCI). This product sets new standards in three-dimensional surface analysis with measurement resolution at the sub-nanometer level. Taylor Hobson joins AMETEK as part of its Electronic Instruments Group (EIG) --a recognized leader in advanced monitoring, testing, calibrating and display instruments. AMETEK EIG sells its instruments to the process, aerospace, power, and industrial markets worldwide and had 2003 sales of approximately $560 million. MORE
