NEW YORK, Sept. 11, 2013 /PRNewswire/ -- Attorney Advertising -- Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of the securities of Active Power Inc. ("Active Power" or the "Company") (NasdaqCM: ACPW). The investigation focuses on whether the Company and its executives violated federal securities laws. On September 6, 2013, shares of Active Network fell $0.48 or 13.71% to close at $3.02 after the Company retracted its guidance after the close of trading on September 5, 2013. 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 Company represented that this relationship with Digital China would allow the Company to increase its revenues and profitability. Then on September 5, 2013, after close of trading, the Company retracted its guidance, citing disappointing results in China. The Company attributed the Company's poor result 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."
