Chairman and Chief Executive Officer Guohong Zhao commented, “We are pleased to report significant revenue growth in the fourth quarter 2012 exceeding our guidance, mainly driven by the delivery of a backlog of orders from previous quarters. In addition, sales revenue from heat exchange units increased over 182% as a result of China’s rapid urbanization. Despite the increase in the fourth quarter sales, we continued to face a challenging operating environment in the face of macroeconomic headwinds and competitive pressure, which coupled with increased labor and raw materials costs, resulted in a decline in our gross margin for the fourth quarter.

“Looking to the year ahead, we expect to face continuing macroeconomic and industry specific headwinds, namely increasing competition and further margin pressure as labor and raw materials costs are forecasted to remain high. Nevertheless, we expect that sales from heat exchange units will continue to benefit from ongoing development and urbanization in China, providing stability and growth prospects in certain end markets. In order to maximize our growth prospects in the year ahead, we will complement our sales efforts in key end markets with an increased focus on expanding sales of replacement parts and repair services. Having completed over 3,000 installation projects in recent years, we are now in a phase that many of these installations are gradually approaching the end of their product lifecycles, requiring replacement parts and repair services which we believe will create new revenue streams for the Company. In addition, we will continue to invest in research and development to improve and further diversify our product portfolios and support the long-term growth prospects for the Company.”

Fiscal Year 2012 Audited Financial Results

Revenue
Sales revenue for the fiscal year 2012 was US$62.8 million, an 8.7% increase from US$57.7 million in 2011, primarily attributable to increased demand of heat exchange units in response to rapid urbanization in China. Sales volume of heat exchange products amounted to 3,726 units, a decrease of 407 units from 4,133 units in 2011. Such decrease was mainly due to decreased sales from plate heat exchangers (PHEs) and air-cooled heat exchangers.

For the fiscal year 2012, sales revenue from heat exchange units increased US$12.2 million, or 98.7% year-over-year, to US$24.6 million. Sales revenue from PHEs decreased 18.9% year-over-year to US$24.2 million from US$29.9 million in 2011. Sales revenue from air-cooled heat exchangers decreased 50.1% year-over-year to US$1.7 million from US$3.5 million in 2011. The decreased revenue from PHEs and air-cooled heat exchangers was mainly due to decreased demand from the petrochemical and shipbuilding industries as a result of the overall economic slowdown in China in 2012.

Cost of Sales
Cost of sales for the fiscal year 2012 increased by 26.5% year-over-year to US$41.1 million from US$32.5 million in 2011, mainly attributable to increased total labor costs in factory and raw material costs in 2012.

Gross Profit and Gross Margin
Gross profit for 2012 was US$21.7 million, representing a 14.2% decrease from US$25.2 million in 2011, mainly attributable to decreased sales from PHEs and air-cooled heat exchangers.

Gross margin decreased to 34.5% in 2012 compared to 43.7% in 2011, mainly due to an increase in labor costs in factory and raw material costs in 2012.

Operating Expenses
Administrative expenses increased 5.2% year-over-year to US$5.9 million in 2012, compared to US$5.6 million in 2011. The rise was driven primarily by higher allowance for doubtful accounts. The overall increase in administrative expenses was partially offset by a decrease in our office expenses which decreased by $0.60 million to $1.29 million in 2012 compared with $0.69 million in 2011. The decrease was mainly due to a reduction in the office purchase in 2012.

Research and development (R&D) expenses rose by 27.1% to US$2.2 million in 2012 from US$1.8 million in 2011, primarily due to the Company’s increasing emphasis on R&D and expanded investment in the development of new products such as HBLB welded plate heat exchangers and large-scale nuclear class plate heat exchangers in 2012.

Selling expenses totalled US$8.2 million in 2012, representing a decrease of 4.0% over 2011, mainly due to a decrease in salaries of the Company’s sales personnel.

Accordingly, total operating expenses increased by 2.7% to US$16.3 million in 2012 compared to US$15.9 million in 2011.

Income Before Income Taxes
Income before income taxes for the fiscal year 2012 decreased by 57.2% to US$3.9 million from US$9.1 million in 2011. The decrease was mainly attributable to the decreased gross profit and increased total expenses.

Income Tax
Income tax expenses decreased to US$0.7 million in 2012 from US$1.6 million in 2011 as a result of a decrease in taxable income.

Net Income
Net income attributable to common stockholders was US$3.2 million in 2012, a decrease of 60.0% compared to US$7.9 million in 2011.

Basic and fully diluted net income per share was US$0.15 in 2012, compared with US$0.39 in 2011.

Liquidity
As of December 31, 2012, the Company had cash and cash equivalents of US$10.7 million and restricted cash of US$1.8 million. During the year, there was a net cash inflow of US$3.4 million, compared with a net cash outflow of US$11.1 million in 2011.

Net cash provided by operating activities was US$4.2 million for 2012, compared with net cash used in operating activities of US$13.1 million for 2011. The increase in net cash provided by operating activities was mainly because the inventories increased US$18.0 million in 2011 but decreased US$0.9 million in 2012.

Net cash used in investing activities was US$1.4 million for 2012, compared with US$6.2 million for 2011.

Net cash provided by financing activities was US$0.5 million for 2012, compared with US$7.8 million for 2011.
