Cleantech Solutions Notified by NASDAQ of Non-Compliance with $1.00 Minimum Closing Bid Price Requirement

Wuxi, Jiangsu Province, China – September 12, 2011 – Cleantech Solutions International, Inc. (“Cleantech Solutions” or “the Company”) (NASDAQ: CLNT), a manufacturer of metal components and assemblies, primarily for the wind power industry as well as solar and other industries, today announced that on September 8, 2011, it received a staff deficiency notice from The Nasdaq Stock Market informing the Company that its common shares have failed to comply with the $1.00 minimum bid price required for continued listing on The Nasdaq Global Market under Nasdaq Listing Rule 5450(a)(1). The Company failed to meet this test because the closing bid price for the Company’s common stock for each trading day in the 30 day period from July 27, 2011 to September 7, 2011 was less than $1.00 per share.

Nasdaq’s letter stated that to regain compliance, the closing bid price for the Company's common stock must be at least $1.00 for a minimum of 10 consecutive business days within the 180-day compliance period ending on March 6, 2012.  In the event the Company does not regain compliance within this period, it may be eligible for additional time by filing a listing application to transfer its common stock to the Nasdaq Capital Market.

“We recognize the importance of maintaining our listing on the Nasdaq Stock Market and are evaluating several options to regain compliance, including a reverse stock split,” commented Mr. Jianhua Wu, Chairman and CEO of Cleantech Solutions.
