Interphase Announces Third Quarter 2010 Financial Results

PLANO, Texas — October 28, 2010 — Interphase Corporation (NASDAQ: INPH), a leading global provider of solutions for converged communications networks, today reported financial results for its third quarter ended September 30, 2010.

Revenues for the third quarter of 2010 were $4.8 million compared to $4.4 million for the third quarter of 2009. Revenues in the quarter were primarily derived from broadband telecom revenues, which increased slightly to $3.7 million in the third quarter of 2010 compared to $3.6 million for the third quarter of 2009. Enterprise revenues increased to $438,000 compared to $211,000 on a year to year basis, while professional services revenues were flat at approximately $370,000. Gross margin for the third quarter of 2010 was 49% compared to 25% for the third quarter of 2009. The increase in gross margin percentage was primarily due to a shift in product mix toward higher margin products, and to a lesser degree, increased utilization of our manufacturing facility and reduction in obsolete inventory charges. Third quarter 2010 operating expenses included a $3.3 million restructuring charge. The charge relates to the project initiated in September of 2010 and is intended to result in savings of approximately $5.5 million in annualized operating costs. The company reported a third quarter 2010 net loss of $4.3 million, or ($0.63) per share compared to a net loss of $2.4 million, or ($0.34) per share in the third quarter of 2009.

“At the close of our third quarter we made the very difficult decision to restructure our operations in an effort to bring spending in line with recent revenue levels and to neutralize the cash usage that we have been experiencing,” said Gregory B. Kalush, CEO and President of Interphase. “Although we generated revenue growth both sequentially and on a year-over-year basis, it was not sufficient to support the infrastructure that was in place. We remain focused on continuing to grow our revenues through product sales and diversification efforts while continuing to invest in key strategic areas of the business.”

For the first nine months of 2010, revenues decreased to $12.4 million, compared to $20.9 million for the first nine months of 2009. Gross margin decreased to 48% for the nine months ended September 30, 2010, compared to 51% for the same period in 2009. The company reported a net loss of $8.9 million, or ($1.30) per share for the first nine months of 2010 compared to a net loss for the first nine months of 2009 of $1.6 million, or ($0.23) per share. The net loss for the first nine months of 2010 is inclusive of a restructuring charge of $3.3 million. There were no restructuring charges during the first nine months of 2009. On September 30, 2010, the company’s working capital position was $12.4 million, including cash and marketable securities of $13.4 million.
