Interphase Announces Third Quarter 2008 Financial Results

PLANO, Texas — October 23, 2008 — Interphase Corporation (NASDAQ: INPH), a leading international supplier of next-generation networking technologies, today reported financial results for its third quarter ended September 30, 2008.

Revenues for the third quarter of 2008 were $6.9 million compared to $8.4 million in the third quarter of 2007. On a sequential basis revenues increased approximately 4% from $6.7 million in the second quarter of 2008. Revenues in the quarter were primarily driven by broadband telecom revenues, which decreased 10% to $6.5 million in the third quarter of 2008 compared to $7.2 million for the third quarter of 2007. On a sequential basis broadband telecom revenues increased approximately 5% from $6.2 million in the second quarter of 2008. Enterprise product line revenues decreased to $106,000 compared to $976,000 on a year to year basis and compared to $196,000 on a sequential basis. Gross margin for the third quarter of 2008 was 58% compared to 61% for the third quarter of 2007. The decrease in gross margin was primarily due to a shift in product mix and reduced utilization of the manufacturing facility. On a sequential basis however, gross margin increased from 47% in the second quarter of 2008. This sequential increase in gross margin was primarily driven by improved product mix. The company reported a net loss of $55,000 or ($0.01) per share for the third quarter 2008, compared to a net income of $698,000, or $0.10 per share in the third quarter of 2007 and compared to a net loss of $1.2 million, or ($0.18) per share in the second quarter of 2008.

“We are encouraged that we were able to deliver sequential revenue growth along with an improvement to our gross margins and our bottom line performance. The first nine months of this year have been a challenge for many of our customers, and therefore for us, as we continue to see unpredictable forecasting and buying patterns from customers as they navigate through a very competitive global market.” said Gregory B. Kalush, CEO and President of Interphase. “We are excited, however, about the expansion of our packet accelerator product line with the recent general availability announcement of our iSPAN 55MC8, as well as the inclusion of our products in ASN Gateways, WiMax and Femtocell solutions. The rollout of both AMC and PCI-e solutions is equally encouraging because we are beginning to see new activity in a market that has been stalled for quite some time.”

For the first nine months of 2008, revenues decreased approximately 4% to $21 million, compared to $21.8 million for the first nine months of 2007. Gross margin decreased to 54% for the nine months ended September 30, 2008, compared to 59% for the same period in 2007. Net loss for the first nine months of 2008 was $1.7 million or $(0.28) per share compared to $764,000 or $(0.13) per share. Included in operating expenses for the first nine months of 2008 is a $403,000 restructuring charge. The charge relates to the plan announced in March of 2008 and was undertaken to reduce future annual operating expenses, anticipated to be over $1.5 million annually. The company’s balance sheet continues to be strong with a working capital position of $24.6 million, including cash and marketable securities of $17.8 million on September 30, 2008.
