Specifically, on April, 30, 2013, the company's Chief Executive Officer, Doug Milner, announced that Active Power had entered into a strategic distribution agreement with China's largest IT solutions provider, Digital China Information Service Company. Further, Mr. Milner emphasized that collaborative efforts with Digital China were under way that would lead to product deployments by the end of 2013. As a result, Active Power shares traded at artificially inflated prices during the Class Period. Active Power Stock Drops on Retraction of Third Quarter Guidance On September 5, 2013, according to the complaint, Active Power retracted its 2013 guidance based on disappointing results from the company's distribution relationship in China. Moreover, the company also revealed that its April 30, 2013 announcement that it had entered into a partnership with Digital China was incorrect. The agreement was with an unrelated entity, Qiyuan Network System Limited. On this news, Active Power's stock prices fell $0.48, or nearly 14%, to close at $3.02 on September 6, 2013.
