First Quarter 2015 Financial Results

Revenue
Sales revenue for the first quarter of 2015 was US$8.2 million, or 1.4% decrease from US$8.3 million during the same period of 2014. The decrease was primarily attributable to lower sales revenue from plate heat exchangers and shell-and-tube heat exchangers. Sales volume of heat exchange products was 362 units in the first quarter of 2015, a decrease of 134 units from 496 units in the same period of 2014. The decrease was due to the decreased demand of our products in consequence of fewer projects and economy slowdown of China in the first quarter of 2015 compared with the previous years.

Cost of Sales
Cost of sales for the first quarter of 2015 increased 0.1% to US$5.8 million from US$5.8 million in the first quarter 2014. The increase was mainly attributable to the decrease in our sales revenue.

Gross Profit and Gross Margin
Gross profit decreased 4.7% to US$2.4 million during the first quarter of 2015, from US$2.5 million in the same period of 2014, mainly due to the decreased sales revenue. Gross margin was 29.4% for the first quarter of 2015, as compared with 30.5% during the same period of 2014. The decrease in gross margin was mainly attributable to the decrease in our sales revenue.

Operating Expenses
Administrative expenses decreased 44.6% to US$0.3 million in the first quarter 2015, from US$0.6 million for the same period of 2014. The decrease was primarily owing to the decrease of allowance for doubtful accounts in the first quarter of 2015.

Research and development expenses decreased 37.9% year-over-year to US$0.2 million, from US$0.3 million in the first quarter 2014. The decrease was primarily due to a decrease in the costs of research and development of new products.

Selling expenses decreased 16.2% to US$0.8 million for the first quarter of 2015, from US$1.0 million during the same period of 2014. The decrease was mainly attributable to a decrease of travelling expenses.

Income before Income Tax

Net cash used in operating activities was US$0.7 million for the first three months of 2015, compared with US$1.9 million for the same period of 2014.
