Symmetricom Reports Fourth Quarter and FY2007 Financial Results

SAN JOSE, Calif. — Aug. 9, 2007 — Symmetricom, Inc. (NASDAQ:SYMM), a worldwide leader in precise time and frequency products and services, today reported financial results for its fourth quarter and fiscal year ended June 30, 2007.

Fiscal fourth quarter revenue was $57.4 million, a 22.8 percent increase over prior year quarterly revenue of $46.8 million.  For the fiscal year ended June 30, 2007, revenue was $208.4 million, an 18.3 percent increase over $176.1 million for fiscal year 2006.

Net earnings from continuing operations in the fourth quarter were $1.4 million or $0.03 per share on a fully diluted basis, compared with net earnings from continuing operations of $2.0 million or $0.04 per share on a fully diluted basis in the prior year period.  In fiscal 2007, net earnings from continuing operations were $5.9 million or $0.13 per share on a fully diluted basis, compared with a net loss from continuing operations of $46,000 for the prior fiscal year. Net earnings for fiscal year 2007 include a tax provision of $3.4 million, resulting from the liquidation of QoSmetrics S.A. and QoSmetrics, Inc., as previously disclosed.  Net earnings for fiscal year 2006 included a $7.0 million or $0.15 per share charge for the impairment of $6.2 million in goodwill and $0.8 million in other intangibles principally related to the company’s wireless business segment purchased in connection with the Datum acquisition in October 2002; this was determined in accordance with SFAS 142 for goodwill and SFAS 144 for other intangibles.

Non-GAAP net earnings from continuing operations in the fourth quarter, which excludes certain items related to non-cash compensation, amortization of acquired intangibles, integration and restructuring charges, and unusual and non-recurring items, were $4.0 million or $0.09 per share on a fully diluted basis compared with $3.8 million, or $0.08 per share on a fully diluted basis for the prior year period.  Non-GAAP net earnings from continuing operations for fiscal 2007 of $17.5 million or $0.38 per share on a fully diluted basis are up from prior year net earnings from continuing operations of $15.2 million or $0.32 per share on a fully diluted basis.

Telecom Solutions Division (TSD) revenue in the quarter was $36.1 million, an increase of $3.2 million or 9.9 percent over prior year period revenue of $32.9 million.    TSD revenue in fiscal 2007 was $135.2 million, up $18.1 million or 15.5 percent from prior year revenue of $117.1

-more-

million.  The growth in TSD revenues was principally attributable to strong sales of next generation wireline frequency and timing solutions to replace legacy equipment in U.S. central offices.

Timing, Test & Measurement Division (TT&M) revenue in the quarter was $21.2 million, an increase of $7.3 million or 52.5 percent over prior year period revenue of $13.9 million.  TT&M revenue for fiscal 2007 was $72.7 million, up $13.6 million or 23.1 percent from prior year revenue of $59.0 million.  TT&M revenue growth was supported by strong revenue in the secure mobile communications area as well as the acquisition of Timing Solutions Corporation, which was completed on Oct. 2, 2006.

Revenue for our new Quality of Experience Assurance Division (QAD) was $0.1 million for the quarter and $0.5 million for the fiscal year.

“Fiscal 2007 was a banner year for Symmetricom,” said Tom Steipp, president and CEO of Symmetricom.  “We broke through the $200 million revenue level, supported by revenue from equipment upgrades in our Telecom Solutions business and strong sales of secure communications equipment in our Timing Test and Measurement business.”

“Looking ahead, we expect several large upgrade customers to slow ordering as they focus on installing equipment they have just purchased. As a result, we believe that the second half of fiscal 2008 will be stronger than the first half,” continued Steipp.

Fiscal Year 2007 Highlights

·Grew revenue by 18 percent

·Net earnings improved to $6.1 million from $0.8 million in fiscal 2006

·Initiated wireline upgrades at AT&T and Verizon, which both became greater than 10 percent customers

·Introduced CableLabs® qualified DTI server, which is now in trials and vendor testing in the cable market, a new opportunity for the company

·Acquired Timing Solutions Corporation, which adds specialized products and knowledge to the TT&M product portfolio

·Acquired QoSmetrics, S.A. and intellectual property from Genista Corporation to form the nucleus of our new QAD business

Outlook for Fiscal Year 2008

Symmetricom expects fiscal year 2008 revenue to grow to a range of $210.0 million to $220.0 million.  The company expects GAAP earnings to be between $0.05 and $0.15 per share, on a fully diluted basis. Non-GAAP earnings are expected to be between $0.24 per share and $0.34 per share, on a fully diluted basis.

Symmetricom expects fiscal year 2008 first quarter revenue to be between $48.0 million and $53.0 million.  The company expects GAAP earnings to range from a loss of $0.05 per share to breakeven, on a fully diluted basis.  Non-GAAP earnings are expected to be between

2

$0.01 per share and $0.06 per share, on a fully diluted basis.  We will no longer provide quarterly guidance after this earnings release.

Our annual earnings guidance reflects increased operating expenses to support our emerging QAD business. We are investing in this organization during fiscal 2008 to develop this business to its fullest potential. We expect this investment to dilute earnings per share for fiscal year 2008 by approximately $0.22 per share on a GAAP basis and $0.16 per share on a Non-GAAP basis.
