According to the suit, Active Power issued materially false and misleading
statements about its true business and operational condition. On April 30,
2013, Active Power announced that it had entered into a "[n]ew strategic
distribution partnership agreement with Digital China Information Service
Limited, the largest IT solutions provider in China." The Company represented
that this relationship with Digital China would allow the Company to increase
its revenues and profitability, adding that "[w]e have already engaged with
Digital China on large data center projects for which we anticipate field
product deployment later this year." On September 5, 2013, after close of
trading, the Company retracted its guidance, citing disappointing results in
China. The Company added that the poor results were attributable to the fact
that "the company's previously announced agreement in China is with Qiyuan
Network System Limited, which the company's management discovered is neither
an affiliate nor a subsidiary of Digital China Information Service Company
Limited." According to the Complaint, this adverse news caused the price of
Active Power stock to fall, damaging investors.
