SYMMETRICOM REPORTS FISCAL 3RD QUARTER FINANCIAL RESULTS

Company Returns to Profitability and Positive Cash Flow; Revenue Hits Post-Acquisition

High of $43.7 Million

SAN JOSE, Calif. — April 29, 2004 — Symmetricom, Inc. (NASDAQ:SYMM), a leading worldwide supplier of atomic clocks and network synchronization and timing solutions, today reported results for its fiscal third quarter ended March 31, 2004.

Fiscal third quarter revenue was $43.7 million, an increase of $2.8 million, or 6.8 percent, over prior quarter revenue of $41.0 million, and an increase of $6.9 million, or 18.7 percent, over the same period last year. For the nine month period ended March 31, 2004, revenue was $123.2 million, an increase of $28.1 million, or 29.5 percent, over the prior year period. The net profit from continuing operations for the fiscal third quarter was $1.8 million, or $0.04 per share on a fully diluted basis, which compares to a net loss from continuing operations for the prior quarter of $3.9 million, or $(0.09) per share, including a $0.10 per share restructuring charge. The company posted a net loss from continuing operations of $5.4 million, or $(0.13) per share, for the same period last year, which includes acquisition related restructuring charges of $0.03 per share. The net loss from continuing operations for the nine month period ended March 31, 2004, was $4.4 million, or $(0.10) per share, including various acquisition related charges of $0.11 per share. This compares to a net loss from continuing operations in the prior year period of $27.9 million, or $(0.83) per share, including acquisition related charges of $0.57 per share.

Comparison of nine month revenue and net loss results may not be meaningful as prior year results do not include full period results for Datum and TrueTime, which were both acquired in October 2002.

“All of our hard work over the last year has resulted in the company’s return to profitability,” said Thomas Steipp, chief executive officer of Symmetricom. “Revenue hit a post-acquisition high on the strength of our wireline, wireless and government businesses, while our continued focus on cost control and efficiency led to improved gross margins, exclusive of restructuring costs, for the fourth consecutive quarter. We are also pleased that our strong performance increased our cash and investment balances to $36.2 million in the third fiscal quarter from $28.9 million at the end of the prior quarter.”

Outlook for Q4 FY04

Symmetricom expects fiscal fourth quarter revenue to be between $43 million and $48 million and fiscal fourth quarter earnings to be between $0.04 and $0.07 per share. As a result of the acquisitions of Datum and TrueTime, Symmetricom has excess office and manufacturing space that it is seeking to sub-lease. Should Symmetricom be unable to find tenants for these vacant facilities, the company will have to take an additional lease impairment charge that will impact operating results.
