With strong customer demand, and timely recovery by our Asia operations after the Chinese New Year shutdown, we delivered higher than originally guided quarterly sales. With our focus on operational excellence, we achieved a record gross margin level, above 36%, which resulted in a 100% increase in profits, compared with a year ago quarter.”

“More importantly, customers demand remains strong after March. Based on input from our customers and current expectations regarding orders, we expect revenues to increase to a record level above $14M in the second quarter of 2013, which would represent more than 20% growth from the year ago quarter. With such a strong beginning, we are encouraged by the prospect of delivering both record revenues and record profits for the year of 2013.” concluded Mr. Chang.
