Fewer sales of its semiconductor testing equipment contributed to Trio-Tech International posting a net loss for the first quarter. The Van Nuys-based firm reported a net loss of $804,000, or $0.24 per diluted share, on revenues of $8.8 million for the quarter ending Sept. 30. For the same period in 2010, the company had net income of $491,000, or $0.14 per diluted share, on revenues of $13 million. Trio-Tech executives are optimistic that a strategy of diversifying beyond the core semiconductor test equipment business will result in improved financial results. The company has made investments in real estate in China and an oil and gas equipment fabrication division. “We are working hard to bring our costs into line with the current pace of business, even as we seek to expand our operations with existing customers and attract new customers in all of our operating segments,” said Trio-Tech CEO SW Yong said in a prepared statement.
