Active Power Accused of Making False and Misleading Statements

According to the complaint, Active Power issued materially false and
misleading statements about the company's success in expanding its business
into the lucrative Chinese market. 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.
