With the purpose of improving our prospects of steady growth, the Company will continually focus on maintaining competitive advantage in substantial market and expanding sales of components and maintenance service. Meanwhile, manufacturing and sales of more products with high technology and high added value will be a new profit growth engine for our long-term development.”

Fiscal Year 2013 Audited Financial Results

Sales Revenue

Sales revenue for the fiscal year 2013 was US$71.8 million, a 14.4% increase from US$62.8 million in 2012, primarily attributable to increased demand of heat exchange units in response to rapid urbanization in China. Sales volume of heat exchange products amounted to 3,418 units, a decrease of 308 units from 3,726 units in 2012. Unit price increased 24.8%, to US$21,017 in 2013 from US$16,846 in 2012. Such increase was mainly because we manufactured more products with high price and costs to suit our customers’ higher requirements.

For the fiscal year 2013, sales revenue from heat exchange units increased US$7.0 million, or 28.4% year-over-year, to US$31.6 million. Sales revenue from air-cooled heat exchangers increased 143.37% year-over-year to US$4.2 million from US$1.7 million in 2012. The increased revenue from heat exchange units and air-cooled heat exchangers was mainly due to increased demand for our products as a result of the overall economic recovery in China in 2013.

Cost of Sales

Cost of sales for the fiscal year 2013 increased by 20.8% year-over-year to US$49.7 million from US$41.1 million in 2012, mainly attributable to our increased sales revenue in 2013.

Gross Profit and Gross Margin

Gross profit for 2013 was US$22.2 million, representing a 2.3% increase from US$21.7 million in 2012, mainly attributable to increased sales from heat exchanger units and air-cooled heat exchangers.

Gross margin decreased to 30.9% in 2013 compared to 34.5% in 2012, mainly due to an increase in labor costs and raw material costs consorted with the special products as mentioned above in 2013.

Operating Expenses

Administrative expenses increased 45.9% year-over-year to US$8.6 million in 2013, compared to US$5.9 million in 2012. The rise was driven primarily by higher bad debt expense. The increase in bad debt expense was mainly caused by China’s tightened credit policy which gave rise to delayed delivery schedules and delayed payments by our customers.

Research and development (R&D) expenses rose by 18.8% to US$2.6 million in 2013 from US$2.2 million in 2012, primarily due to the higher costs of raw materials used in R&D.

Selling expenses totalled US$5.9 million in 2013, representing a decrease of 28.0% over 2012, mainly due to a decrease in our sales personnel’s travelling expenses.

Accordingly, total operating expenses increased by 5.1% to US$17.2 million in 2013 compared to US$16.3 million in 2012.

Income before Income Taxes

Income before income taxes for the fiscal year 2013 increased by 7.3% to US$4.2 million from US$3.9 million in 2012. The decrease was mainly attributable to the increased gross profit.

Income Tax

Income tax expenses decreased to US$1.1 million in 2013 from US$0.7 million in 2012 as a result of an increase in taxable income.

Net Income

Net income attributable to common stockholders was US$3.1 million in 2013, a decrease of 2.2% compared to US$3.2 million in 2012.

Basic and fully diluted net income per share was US$0.1494 in 2013, compared with US$0.1546 in 2012.

Net cash provided by operating activities was US$2.9 million for 2013, compared with net cash used in operating activities of US$4.3 million for 2012. The decrease in net cash provided by operating activities was mainly because an US$8.2 million decrease in other payables and accrued expenses, and a US$1.2 million increase in allowance for doubtful accounts.
