Interphase Announces First Quarter 2014 Financial Results

CARROLLTON, Texas – May 6, 2014 -- Interphase Corporation (NASDAQ: INPH), a diversified information and communications technology company, today reported financial results for its first quarter ended March 31, 2014.

Revenues for the first quarter of 2014 were $3.4 million, an increase of 5% when compared to revenues from the first quarter of 2013 of $3.3 million. Revenues in the quarter were primarily derived from communications networking product revenues, which decreased 32% to $1.7 million in the first quarter of 2014 compared to $2.5 million for the first quarter of 2013. However, services revenues increased approximately 128% to $1.6 million in the first quarter of 2014 compared to $722,000 in the first quarter of 2013 and represented 48% of first quarter 2014 revenues. Gross margin was 31% for the first quarter of 2014 compared to 39% for the first quarter of 2013. The decrease in gross margin percentage was primarily due to a revenue mix shift toward lower margin services, partially offset by increased utilization of our manufacturing facility. The Company reported a net loss of $1.0 million, or ($0.14) per share in the first quarter of 2014 compared to a net loss of $1.4 million, or ($0.20) per share in the first quarter of 2013. On March 31, 2014, the Company’s working capital position was $8.8 million, including cash and marketable securities of $5.2 million.

“We are pleased with the revenue growth in the first quarter of 2014 over 2013, especially in our services offerings, however, revenues from our communications networking customers fell nearly $900,000, and the negative product mix impact on gross margin curbed our bottom line performance,” said Gregory B. Kalush, CEO and President of Interphase. “We expect to see some restoration of our communications networking revenues which should improve the gross margin mix in the second quarter as one of our largest customers resumes purchases after having worked off excess inventories. We remain on schedule for shipping penveu^® in May, and have continued to receive positive feedback during the quarter from local Independent School District technology exhibits we have attended. We are very excited about the prospects that this product will have in the marketplace as it helps improve the way our children learn and businesses communicate information.”
