Completes merger-related consolidation of worldwide manufacturing operations

 San Jose, CA—January 6, 2004— Symmetricom Inc. (NASDAQ: SYMM), a leading supplier of network synchronization and timing solutions for the global telecommunications industry, announced the formal closure of its Irvine, California manufacturing site. This closure, announced in May 2003, completes the integration of Symmetricom’s Technology Research Center into a single facility located in Beverly, MA. It is also the final facility consolidation associated with the company’s acquisitions of Datum, Inc. and TrueTime. Integration activities conducted since the mergers closed have reduced Symmetricom's active square footage from over 450,000 in October 2002 to less than 295,000 today and are expected to save the company $30M in annual operating expenses.

Operations in the Irvine area began in 1969 with the founding of Datum and expanded when that company acquired Efratom and its rubidium oscillator product line in 1995. The Irvine site employed approximately 150 people in two separate buildings. As part of the consolidation, operations for the company's rubidium-based atomic frequency standards have successfully been moved to Symmetricom’s Technology Realization Center (TRC) in Beverly, MA. The TRC produces precise time and frequency standards based upon the unique atomic properties of quartz, rubidium, cesium and hydrogen. These atomic standards are essential for a broad array of applications including systems for telecommunications, metrology, as well as space, defense and avionics.
