Cleantech Solutions International Reports Third Quarter 2011 Results

Wuxi, Jiangsu Province, China – November 15, 2011 –Cleantech Solutions International, Inc. (“Cleantech Solutions” or “the Company”) (NASDAQ: CLNT), a manufacturer of metal components and assemblies, primarily used in the wind power, solar and other clean technology industries, today announced its financial results for the three and nine months ended September 30, 2011.

“We continue to face challenging market conditions and pricing environment, due to delayed capital expenditures by our wind power and other industrial customers in light of the PRC government’s tightening monetary policy,” commented Mr. Jianhua Wu, Chairman and Chief Executive Officer of China Wind Systems.

“We continue to make progress in diversifying our product offering and are optimistic about the evolution of our solar business.  We are also gaining traction in other clean energy areas, recently receiving sample orders for key components for Sapphire Growth System used in the manufacture of LED general lighting applications.  At quarter end, we had a backlog of $1.8 million in solar products and LED equipment and sample orders. We are confident our fabrication and welding expertise will allow us to further penetrate these and other areas of clean energy,” Mr. Wu concluded.

Third Quarter 2011 Results

Revenue for the third quarter of 2011 declined 45.1% to $11.7 million, compared to $21.3 million for the same period of 2010. The decline in revenue was mainly attributable to a slowdown in sales and decreased selling prices of the Company’s forged rolled rings and related products associated slower growth rate in the wind industry and increased competition. In addition, the dyeing and finishing equipment segment experienced a decline in sales largely due to the business cycle and customer delays in purchasing new equipment designed to meet the PRC government's mandatory environmental protection policies, due to monetary tightening policies implemented by the Chinese government.

Revenue from the sale of forged rolled rings to the wind power industry and other industries decreased 51.5% to $7.6 million, or 65.2% of revenue, compared to $15.7 million, or 73.9% of net revenue, in the same period last year.

Revenue from the sale of forged rolled rings exclusively to the wind power industry fell 63.9% to $4.5 million, representing 38.5% of revenue, compared to $12.4 million, or 58.4% of revenue, in the comparable period last year.

Revenue from the sale of forged rolled rings to other industries decreased 4.9% to $3.1 million, or 26.7% of revenue, compared with $3.3 million for the comparable period of the prior year.

Revenue from the Company’s dyeing and finishing equipment segment decreased 26.8% to $4.1 million, or 34.8% of net revenues, compared to $5.6 million, or 26.1% of revenue, for the third quarter of 2010.

Gross profit for the third quarter of 2011 decreased 51.5% to $2.6 million, compared to $5.4 million for the same period in 2010. Gross margin decreased to 22.5% during the third quarter of 2011 compared to 25.5% for the same period a year ago. The slight increase in gross margin for the dyeing segment was offset by the decline in gross margin for the forged rolled rings and related products segment, which was largely due to an increase in the cost of raw materials, which could not be fully passed on to the Company’s customers, and lower operational efficiencies as the Company operated at lower production levels.

Operating expenses decreased 22.3% to $1.0 million, compared to $1.3 million in the comparable period last year. The decrease was largely due to decrease in the Company’s selling, general and administrative expenses, which decreased 24.2% year over year due to lower stock-based compensation expenses, lower shipping and travel costs due to lower sales and an adjustment to bad debt expense.

Operating income decreased 60.5% to $1.6 million, compared to $4.1 million for the same period of 2010. Operating margin was 14.0% compared to 19.5% in the third quarter last year.

Earnings before interest, taxes, depreciation and amortization (EBITDA), a non-GAAP measurement, was $2.8 million, compared to $5.1 million in the same quarter last year.

Net income decreased 61.8% to $1.1 million, compared to $3.0 million in the comparable period last year. Basic earnings per share in 2011 and 2010 were $0.06 and $0.16, respectively. Basic earnings per share were calculated using basic weighted average shares of 19,976,741 and 18,177,405 for the three months ended September 30, 2011 and 2010, respectively.  Diluted earnings per share were $0.05, compared to $0.12 in the same period of 2010. Diluted earnings per share were calculated using diluted weighted average shares of 24,621,594 and 25,312,979 for the three months ended September 30, 2011 and June 30, 2010, respectively.

Results for Nine Months

For the nine months ended September 30, 2011, revenues decreased 26.7% to $41.9 million from $57.1 million in 2010. Gross profit decreased 30.9% to $10.2 million, compared to $14.8 million last year.  Gross margin for the nine months ended September 30, 2011 was 24.5%, compared to 26.0% in 2010.  Gross margin for the forged rolled rings segment was 25.7% compared to 27.9% in 2010. For the dyeing and finishing equipment segment, gross margin was 21.4% compared to 20.8% in 2010. Operating income decreased 37.2% to $7.0 million from $11.1 million in 2010. EBITDA was $10.8 million, compared to $13.3 million in the same period last year.  Net income was $5.0 million, a 37.4% decrease from $7.9 million last year. Basic earnings per share for nine months ended September 30, 2011 and 2010 were $0.26 and $0.45, respectively. Diluted earnings per share were $0.20 and $0.32, respectively.

Financial Condition

As of September 30, 2011, Cleantech Solutions held cash and cash equivalents of $0.5 million, down from $0.9 million at December 31, 2010.  Accounts receivable were $8.2 million and total current assets of $17.8 million. The Company had $2.3 million in short-term loans payable, no long-term debt and stockholders’ equity stood at $70.6 million. In the nine months ended September 30, 2011, the Company generated $5.9 million in cash flow from operations.

The Company’s planned capital expenditures for the next twelve months mainly relate to purchase of machinery for the manufacture of products for the solar industry and additional investment for its forged rolled rings and dying equipment segment.  The Company plans to finance these expenditures with cash flow from operations.

Subsequent Events

On October 12, 2011, the Company renewed its loan agreement with Agricultural and commercial Bank in the amount of $468,618. The loan is due on August 31, 2012 with interest at the annual rate of 7.872% and secured by certain assets of the Company.

On November 4, 2011, the Company’s board of directors approved for a one-for-five reverse split of its common stock and a reduction in the number of authorized shares of common stock.  These changes will be reflected in an amendment to the Company’s certificate of incorporation and are subject to stockholder approval.  This action by the board of directors superseded previous authorization for a one-for-three reverse split.

Business Outlook

Cleantech Solutions continues to implement its strategy of diversifying its businesses to other areas of clean energy to partially offset the recent decline in sales from the wind energy sector and other industrial customers.  Despite the apparent decline in the growth rate for the wind power industry in China, the Company believes the wind power market still provides significant opportunity for growth over the next few years, supported by Chinese government targets for additional installed capacity of 90 GW by 2015.  However, the Company is facing increased competition, which has affected its pricing, and it expects competition to continue to increase.

The Company has a growing pipeline of customers from other clean technology application areas and has received positive feedback from end customers in the solar and LED general lighting industries. The Company is on schedule to complete and ship its LED sample products before the end of the year and anticipates follow-on orders in 2012.  In addition, it also expects the airflow dyeing machines will gain traction in the coming months.

Mr. Wu concluded, “Our strategy remains unchanged as we continue to explore new markets in other clean technology industries given anticipated softness in the wind power and traditional dyeing equipment in the remainder of 2011.  We will focus on seeking new customers and completing sample orders from our customers in the solar and LED general lighting industries, which will be important catalysts for the Company’s revenue and profitability going forward.”
