Chairman and Chief Executive Officer Guohong Zhao commented, “We continued to build on the positive momentum generated in recent quarters and ended 2010 with a very solid performance. Top-line growth, which exceeded our guidance in the fourth quarter, contributed to more than 44% increase in revenues for the full year. At the same time, our focus on optimizing both our product mix and cost structure allowed us to almost double our net income in 2010.

“Our diverse product lines enable us to cater to a broad range of customers and end users as we capitalize on several key trends that are driving the clean technology movement in China. As China faces pressures from rapid urbanization, our heat exchanger units offer efficient and effective solutions to provide heating systems to growing populations in cities throughout China. In addition, our air-cooled exchangers enable water-deficient areas in Northern China to conserve and better utilize a very limited resource. As businesses recognize the cost effectiveness of switching to clean technology solutions and are further incentivized by government stimulus plans, our plate heat exchange (“PHE”) products are quickly gaining traction across a range of industrial sectors, including the metallurgy, petrochemical and shipbuilding industries.

“As rapid urbanization and government stimulus plans designed to support carbon reduction initiatives continue to drive demand for energy efficient platforms, our broad product portfolio, integrated solutions and excellent track record of high quality applications have well prepared us to capitalize on these favorable dynamics in 2011. Additionally, our sound balance sheet and cash position, which were further strengthened by our recent fund raising, afford us with financial flexibility to invest in our future and pursue growth opportunities.”

Fiscal Year 2010 Audited Financial Results

Revenue

Sales revenue for fiscal year 2010 was US$50.25 million, a 44.01% increase from US$34.89 million in 2009. The increase was primarily attributable to the strong growth in market demand driven by continued government stimulus for energy-saving initiatives, strong economic growth in China, as well as the Company’s successful market expansion. Revenue growth was also attributable to THT’s extensive sales network, excellent solutions and high quality products.

Sales volume of heat exchange products rose substantially to 3,998 units in 2010, up 66.93% from 2,395 units in 2009. The increase in sales came primarily from three product lines – heat exchanger unit, PHE and air-cooled heat exchanger.

Sales revenue of heat exchanger units was $14.30 million, up 147.23%, or $8.52 million, compared to 2009 due to ongoing rapid urbanization in China. Sales revenue of PHEs in 2010 was $27.02 million, an increase of $5.09 million, or 23.23%, from 2009 primarily due to the increased sales to the metallurgy, petrochemical and shipbuilding industries. Sales revenue from air-cooled heat exchangers increased by $3.34 million, or 495.69%, to $4.02 million in 2010 from $0.67 million in 2009. The growth was primarily driven by strong market demand in water-deficient areas of China.

Cost of Sales

Cost of sales for fiscal year 2010 increased by 42.98% to US$28.55 million from US$19.97 million in 2009. The increase was mainly attributable to the significant improvement in sales volume and sales revenue during the year.

Gross Profit and Gross Margin

Gross profit in 2010 was US$21.70 million, representing a 45.38% increase from US$14.92 million in 2009, mainly attributable to the significant increase in sales in 2010.

Gross margin in 2010 was 43.18%, compared 42.77% in 2009, with an expansion of 0.41 percentage point. This improvement was mainly due to THT’s efforts to optimize its product mix and maximize profitability. In response to the market demand and through intensive sales efforts, the Company significantly increased sales of high gross margin products, which include air-cooled heat exchangers, plate heat exchangers and plate heat exchangers units, to the petrochemical, shipbuilding and heat and power industries.

Operating Expenses

Administrative expenses were US$4.36 million in 2010, representing a 42.25% increase from US$3.06 million in 2009. The increase was driven primarily by a $0.36 million increase in the recruitment of, and compensation paid to, the Company’s expanded management team as well as a $0.47 million rise in the allowance for doubtful accounts.

Research and development (R&D) expenses increased by 5.08% to US$1.15 million in 2010 from US$1.10 million in 2009, primarily due to the Company’s continued efforts to strengthen its R&D efforts and increased investment in the development of new products.

Selling expenses totalled US$6.60 million in 2010, representing an increase of 14.19% over 2009. The increase was primarily due to a $0.52 million rise in travel expenses and transportation costs resulting from market expansion. The salary of sales personnel increased by approximately $0.15 million, or 11.36%, to $1.47 million in 2010 compared to $1.32 million in 2009.

Accordingly, total operating expenses increased by 21.83% to US$12.11 million in 2010 compared to US$9.94 million in 2009.

Income Before Income Taxes

Income before income taxes for fiscal year 2010 increased by 105.55% to US$9.88 million from US$4.81 million in 2009.

Liquidity

As of December 31, 2010, the Company had cash and cash equivalents of US$18.44 million and restricted cash of US$1.68 million. During the year, there was a net cash inflow of US$13.06 million, compared with a net cash outflow of US$7.20 million in 2009. The change was mainly due to the cash flow from financing activities, including the issuance of common stock for approximately $13.39 million (net of expenses) and additional loan proceeds of approximately $2.66 million. In addition, cash flow used in operating activities in 2010 decreased $3.89 million from 2009, mainly due to the increased net income, despite an increase in inventory and higher income tax resulted from higher net income. Prepayment for purchase of raw materials in anticipation of the production requirements for the 2011 was $4.51 million.

First Quarter Fiscal 2011 Guidance

THT expects to generate net revenues in the range of US$12.00 million to US$14.00 million in first quarter fiscal 2011, compared with US$10.13 million in the same period of 2010. This represents the Company’s current and preliminary view, and is subject to change.
