Third quarter 2013 sales revenue totaled US$13.8 million, exceeding guidance

SIPING, CHINA — November 13, 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 third quarter ended September 30, 2013.

Third Quarter 2013 Financial Highlights

• Sales revenue increased by 10.0% year-over-year to US$13.8 million. Sales revenue exceeded the Company’s previously announced guidance of US$12.0 million to US$13.5 million for the third quarter 2013.
• Gross profit decreased by 17.7% year-over-year to US$4.3 million.
• Gross margin was 31.0%, compared to 41.4% for the third quarter 2012.
• Operating income decreased by 6.0% year-over-year to US$0.8 million.
• Net income attributable to common stockholders increased by 38.4% year-over-year to US$0.7 million.
• Basic and fully diluted net income per share was US$0.03, compared with net income per share of US$0.02 for the third quarter 2012.

Chairman and Chief Executive Officer Guohong Zhao commented, “Our third quarter sales revenue exceeded guidance despite the continued market challenges in China. Demand for our plate heat exchangers and heat exchanger units increased due to ongoing demand from the heating industry. However, these revenue gains were offset by cost increases in labor and raw materials, as well as mounting competitive pricing pressure, resulting in a decrease in gross profit. Nevertheless, as a consequence of our continued efforts to cut costs and lower expenses, we have realized a 38% year-on-year increase in net income for the third quarter.”

“As we move into the fourth quarter 2013 and fiscal year 2014, we expect industry and macroeconomic headwinds impacting our business to continue, with increased competition and production costs putting downward pressure on profit margins. In light of the continued economic downturn, we intend to focus our activities in a few key areas, namely sales to the heating industry – where market demand is still healthy, geographic expansion into Northwest China – where government development efforts are intense, and investment in overall research and development. We believe these efforts will position us well for future growth once market conditions improve.”

Third Quarter 2013 Financial Results

Revenue
Sales revenue for the third quarter 2013 was US$13.8 million, a 10.0% increase from US$12.5 million during the same period in 2012, primarily due to increased sales revenue from plate heat exchangers, heat exchanger units and air-cooled heat exchangers. Sales volume of heat exchange products totaled 421 units in the third quarter 2013, a decrease of 283 units from 704 units in the same period of 2012. Unit price increased this quarter as a result of customer demand for a greater number of special products with higher input costs.

In terms of revenue breakdown for the third quarter 2013, sales revenue from plate heat exchangers increased by US$1.1 million, or 25.2%, to US$5.5 million from US$4.4 million in the same period of 2012.

Cost of Sales
Cost of sales for the third quarter 2013 increased 29.6% year-over-year to US$9.5 million from US$7.3 million in the third quarter 2012. The increase was mainly attributable to an increase in costs to produce the special products.

Gross Profit and Gross Margin
Gross profit decreased 17.7% to US$4.3 million during the third quarter 2013, from US$5.2 million in the same period of 2012, mainly due to increased cost of sales.

Operating Expenses
Administrative expenses decreased 43.4% to US$1.3 million in the third quarter 2013, from US$2.4 million for the same period of 2012, primarily due to a decrease in bad debt expense in the third quarter of 2013.

Research and development expenses increased 76.7% year-over-year to US$0.6 million, from US$0.3 million in the third quarter 2012, mainly due to an increase in the costs of raw materials used in research and development.

Selling expenses decreased 4.4% to US$1.6 million for the third quarter 2013, compared with US$1.6 million during the same period of 2012, mainly due to a slight decrease in travelling expenses incurred by the Company’s sales personnel.

Net cash used in investing activities was US$0.3 million for the first nine months of 2013, compared with US$1.1 million for the same period in 2012.
