THT Heat Transfer Technology, Inc. Announces
Second Quarter 2013 Results

SIPING, CHINA — August 14, 2013 — THT Heat Transfer Technology, Inc. (NASDAQ:THTI, “the Company”, or “THT”), a leading provider of heat exchangers and heat exchange solutions in China’s clean technology industry, today announced its unaudited financial results for the second quarter ended June 30, 2013.

Second Quarter 2013 Financial Highlights

• Sales revenue decreased by 2.5% year-over-year to US$10.9 million.
• Gross profit decreased by 16.7% year-over-year to US$4.0 million.
• Gross margin was 36.8%, compared with 43.0% for the second quarter 2012.
• Operating income decreased by 64.0% year-over-year to US$0.7 million.
• Net income attributable to common stockholders was US$0.4 million, compared with US$1.4 million for the second quarter 2012.
• Basic and fully diluted net income per share were US$0.02, compared with US$0.07 for the second quarter 2012.

Chairman and Chief Executive Officer Guohong Zhao commented, “We delivered second quarter sales revenue near the high end of our guidance range as we continued to navigate the challenging market environment in China. Demand for our plate heat exchangers, shell-and-tube heat exchangers and other products remained healthy, and our total unit sales increased by approximately 24%. However, these gains were offset by a decrease in sales revenue from our heat exchange units. Furthermore, ongoing macroeconomic headwinds and competitive industry dynamics, as anticipated, resulted in a decrease in our unit price and an increase in sales of lower margin products.

“In light of ongoing macroeconomic uncertainty in China, we expect to face continuing headwinds in the second half of 2013. While we anticipate that labor costs and raw material prices will remain at an elevated level, and that competitive dynamics will continue to place pressure on our margins, we expect a more stable pricing environment in the second half. Furthermore, we believe that our total solutions business model, diversified and high quality product portfolio and ongoing investment in product development will allow us to remain competitively positioned and return to a growth trajectory as and when market conditions improve.”

Second Quarter 2013 Financial Results

Revenue

Sales revenue for the second quarter 2013 was US$10.9 million, a 2.5% decrease from US$11.2 million during the same period of 2012. The decrease was primarily attributable to lower sales revenue from heat exchange units, offsetting the increase in sales revenue from plate heat exchangers, shell-and-tube heat exchangers and other products. Sales volume of heat exchange products totaled 599 units in the second quarter 2013, an increase of 116 units from 483 units in the same period of 2012. However, unit price decreased in the quarter due to the challenging market environment, resulting in an increased proportion of sales of lower margin products.

For the second quarter 2013, sales revenue from heat exchange units was US$2.8 million, a decrease of 24.1% compared with US$3.6 million in the same period of 2012. Sales revenue from air-cooled heat exchangers increased by 50.2% to US$0.8 million from US$0.5 million in the second quarter of 2012. Sales revenue from shell-and-tube heat exchangers was US$1.3 million, an increase of 4.9% compared to the same period of 2012. During the second quarter 2013, sales revenue from plate heat exchangers totaled US$3.9 million, an increase of 0.9% as compared to the same period of 2012.

Cost of Sales

Cost of sales for the second quarter 2013 increased 8.1% to US$6.9 million from US$6.4 million in the second quarter 2012. The increase was mainly attributable to an increase in the Company’s labor and raw material costs.

Gross Profit and Gross Margin

Gross profit decreased 16.7% to US$4.0 million during the second quarter 2013, from US$4.8 million in the same period of 2012, mainly due to the decreased sales revenue from heat exchange units. Gross margin was 36.8% for the second quarter 2013, as compared with 43.0% during the same period of 2012. The decrease in gross margin was mainly attributable to an increase in the Company’s labor and raw material costs.

Operating Expenses

Administrative expenses increased 87.1% to US$1.5 million in the second quarter 2013, from US$0.8 million for the same period of 2012. The increase was primarily due to an overall rise in administrative expenses in the second quarter 2013, with especially significant increases in transportation costs and allowance for doubtful accounts.

Research and development expenses increased 73.4% year-over-year to US$0.4 million, from US$0.2 million in the second quarter 2012. The increase was primarily due to an increase in the costs of raw materials used in research and development.

Selling expenses decreased 25.5% to US$1.5 million for the second quarter 2013, from US$2.0 million during the same period of 2012. The decrease was mainly attributable to a decrease in salary and travelling expenses incurred by the Company’s sales personnel.

This resulted in a 12.3% increase in total operating expenses to US$3.4 million in the second quarter 2013 from US$3.0 million for the same period of 2012.

Income before Income Tax

Income before income tax was US$0.6 million in the second quarter 2013, a decrease of 58.6% compared with US$1.5 million in the same period of 2012. The decrease was mainly due to a decrease in taxable income.

Income Tax

Income tax was US$0.2 million in the second quarter 2013, compared with US$34,934 in the same period of 2012. The increase was mainly attributable to an adjustment of income tax rebates which requested the Company to pay back adjusted amount of taxes for the period from 2008 to 2012 in the second quarter 2013.

Net Income

Net income attributable to common shareholders was US$0.4 million in the second quarter 2013, a 75.4% decrease compared with US$1.4 million in the same period of 2012.

Net cash used in operating activities was US$4.5 million for the first six months of 2013, compared with US$1.4 million for the same period of 2012. The increase in net cash used in operating activities was mainly attributable to (1) prepayment for the purchase of raw materials and staff advance in the amount of US$6.0 million in anticipation of the production requirements for the upcoming production schedule in the third quarter 2013; (2) the increase in inventory by US$3.0 million; (3) the decrease in trade receivables by US$2.0 million and (4) the decrease in other payables and accrued expenses.

Net cash provided by investing activities was US$59,730 for the first six months of 2013, compared with net cash used in investing activities of US$1.8 million for the same period of 2012.

Net cash used in financing activities was US$4.3 million for the first six months of 2013, compared with net cash provided by financing activities of US$0.6 million for the same period of 2012. The increase in net cash used in financing activities resulted from loan repayment in the amount of US$4.2 million.
