IXYS Announces Results for the Second Fiscal Quarter Ended September 30, 2012

MILPITAS, Calif.--(BUSINESS WIRE)--October 25, 2012--IXYS Corporation (NASDAQ:IXYS), an international power semiconductor and IC company, today announced results for its second fiscal quarter ended September 30, 2012.

Net revenues in the quarter ended September 30, 2012 were $68.5 million, a decrease of $30.5 million, or 30.9%, as compared to net revenues of $99.0 million for the same period in the prior fiscal year.

For the six months ended September 30, 2012, IXYS reported net revenues of $149.3 million, a decrease of $51.5 million, or 25.6%, as compared with net revenues of $200.8 million for the same period in the prior fiscal year.

“Continued weakness in the industrial market has driven our revenues down. Our other traditional markets, which include the telecommunications and medical markets, have also shown weakness in demand. However, given our conservative approach to uncertainty, we braced IXYS for such conditions, refrained from any acquisition and concentrated on profitability, while continuing our focus on R&D and new products introductions,” commented Dr. Nathan Zommer, Chairman and CEO of IXYS. “It is important to note that we continue to retain our strong customer base in the industrial, alternative energy, medical, telecom and transportation markets through a pipeline of new products and design wins. As these markets rebound from the current slowdown, we are poised to return to our growth pattern with higher profitability.”

Cash and cash equivalents totaled $105.3 million at September 30, 2012, an increase of $6.1 million as compared to March 2012. The company had a profitable quarter, with record cash. During the quarter ended September 30, 2012, the company purchased about 221,000 shares of its common stock for about $2.1 million. IXYS can still purchase approximately 1.1 million shares under the current buyback programs.

“In addition to generating significant cash from operations, which resulted in another record quarter end cash balance, IXYS has been proactively monitoring its expenses, evidenced by the fact that our SG&A expenses, expressed in absolute dollars, have been the lowest in the last five quarters,” noted Uzi Sasson, President and CFO of IXYS.

Net income for the quarter ended September 30, 2012 was $2.4 million, or $0.07 per diluted share, as compared to a net income of $10.9 million, or $0.34 per diluted share, for the same quarter in the prior fiscal year. Net income for the six months ended September 30, 2012 was $8.4 million, or $0.26 per diluted share, as compared to a net income of $20.9 million, or $0.64 per diluted share, for the same period in the prior fiscal year.

Gross profit was $20.5 million, or 30.0% of net revenues, for the quarter ended September 30, 2012, as compared to gross profit of $31.5 million, or 31.8% of net revenues, for the same quarter in the prior fiscal year.

Gross profit for the six months ended September 30, 2012 was $47.7 million, or 31.9% of net revenues, as compared to a gross profit of $66.5 million, or 33.1% of net revenues, for the same period in the prior fiscal year.

“The credit constraints in Europe and the dramatic slowdown in Asia have adversely affected our performance,” stated Uzi Sasson, President and CFO of IXYS. “The feedback that we get from our suppliers and customers indicates that market volatility still prevails; therefore, we expect revenues for the December 2012 quarter to be relatively flat as compared to the revenues for the September 2012 quarter.”
