Comment from Zhao Guohong, Chairman and CEO

Chairman and Chief Executive Officer Guohong Zhao commented, “Against a challenging economic environment in China, we delivered a steady financial performance in the first quarter with revenues exceeding our guidance. Demands for our heat exchange units and shell-and-tube heat exchangers maintained steady growth, and our total unit sales increased by approximately 30%. Due to the increased labor costs and raw material costs, however, our gross profit decreased about 16% and our gross profit margin dropped to 31% from 38%.

“Along with ongoing macroeconomic uncertainty in China, we expect to face continuing headwinds in the second quarter of 2014. However, we believe that our total solutions business model and ongoing investment in high technology and high added value products will enable us to continuously increase our competitiveness and remain sustained growth.”

First Quarter 2014 Financial Results

Revenue
Sales revenue for the first quarter of 2014 was US$8.3 million, a 4.8% increase from US$7.9 million during the same period of 2013.

Sales volume of heat exchange products totaled 496 units in the first quarter of 2014, an increase of 113 units from 383 units in the same period of 2013. The increase was due to the increased demand of our products in consequence of more projects and economy recovery of China in the first quarter of 2014 compared with previous years.

Cost of Sales
Cost of sales for the first quarter of 2014 increased 17.2% to US$5.8 million from US$4.9 million in the first quarter 2013. The increase was mainly attributable to an increase in the Company’s labor costs and raw material costs.

Gross Profit and Gross Margin
Gross profit decreased 15.6% to US$2.5 million during the first quarter of 2014, from US$3.0 million in the same period of 2013, mainly due to the increased cost of sales.

Operating Expenses
Administrative expenses decreased 47.1% to US$0.55 million in the first quarter 2014, from US$1.0 million for the same period of 2013.

Income before Income Tax
Income before income tax was US$0.6 million in the first quarter of 2014, an increase of 43.1% compared with US$0.4 million in the same period of 2013. The increase was mainly due to a decrease in our total expenses.
