SYMMETRICOM REPORTS FISCAL 4th QUARTER and FY2004 RESULTS

Fourth Quarter Revenue Up 34 Percent Year-Over-Year; Fifth Quarter of Sequential Revenue

Growth

SAN JOSE, Calif. — July 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 fourth quarter and fiscal year ended June 30, 2004.

Fiscal fourth quarter revenue was $49.7 million, an increase of $5.9 million, or 13.5 percent, over prior quarter revenue of $43.7 million, and an increase of $12.7 million, or 34.5 percent, over the same period last year. The net earnings from continuing operations for the fiscal fourth quarter was $2.1 million, or $0.05 per diluted share, which includes a pre-tax charge of $956,000 for costs related to lease impairment and environmental remediation of facilities that were previously owned by Datum and TrueTime, partially offset by the sale of obsolete Datum inventory. Net earnings from continuing operations for the prior quarter were $1.8 million, or $0.04 per diluted share. For the same period last year, the company posted a net loss from continuing operations of $6.5 million, or $(0.15) per share, which included a pre-tax charge of $4.4 million for integration and restructuring costs, partially offset by a favorable adjustment in goodwill impairment.

For the fiscal year ended June 30, 2004, revenue was $172.8 million, an increase of $40.8 million, or 30.9 percent, over the prior year. The net loss from continuing operations for fiscal 2004 was $2.3 million, or $(0.05) per share, which includes a pre-tax charge of $8.5 million for various acquisition-related restructuring and integration costs. The company posted a net loss from continuing operations for the prior fiscal year of $34.3 million, or $(0.96) per share, which included pre-tax acquisition-related restructuring costs and charges of $25.3 million. Comparison of full year 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.

“Business activity in our fiscal fourth quarter was very strong, resulting in sequential revenue growth in all of our business segments and the fifth consecutive quarter of overall revenue growth,” said Tom Steipp, president and CEO of Symmetricom. “We made continuing improvements in gross margin and generated $11.4 million in cash, bringing our cash balances to $47.6 million.

“As for the year, we significantly reduced infrastructure costs and expanded revenue while successfully completing the integration of Datum and TrueTime. As a result, we returned Symmetricom to profitability in the third quarter,” continued Steipp. “A substantial part of this year’s growth has come from our unique position within the installed base and our ability to support the wireline synchronization upgrade cycle. We will continue to focus on this as a major opportunity going forward.”

Fiscal Year 2004 Highlights

• Five quarters of sequential revenue growth

• Returned to profitability and positive cash flow in the fiscal third quarter

• Three independent operators have initiated the upgrade of their wireline synchronization networks

• Gross margin improved to 40.5% in the fiscal fourth quarter versus 31.0% for the same period last year

• Upgraded the Quality Assurance program to TL 9000 certification for San Jose and Puerto Rico facilities

Outlook for Q1 FY05

Symmetricom expects fiscal first quarter FY05 revenue to be within a range of $48 million and $53 million. The company expects earnings per share to be between $0.04 and $0.08 per share.
