Khang & Khang LLP (the "Firm") announces the filing of a class action lawsuit against Pattern Energy Group Inc. ("Pattern" or the "Company") (Nasdaq: PEGI). Investors who purchased or otherwise acquired shares between May 9, 2016 and November 4, 2016 inclusive (the "Class Period"), are encouraged to contact the Firm prior to the January 10, 2017 lead plaintiff motion deadline. If you purchased shares of Pattern during the Class Period, please contact Joon M. Khang, Esquire, of Khang & Khang LLP, 18101 Von Karman Avenue, 3rd Floor, Irvine, CA 92612, by telephone: (949) 419-3834, or by e-mail at firstname.lastname@example.org. There has been no class certification in this case. Until certification occurs, you are not represented by an attorney. You may choose to take no action and remain a passive class member. The complaint alleges that through the Class Period, Pattern made false and misleading statements and/or failed to disclose: that the Company's operations were deficient with respect to various transaction, process level, and monitoring controls; that Pattern lacked effective internal financial controls; and that as a result of the above, the Company's public statements were materially false and misleading at all relevant times. On November 7, 2016, Pattern announced that it had a material weakness in internal controls over financial reporting. Pattern stated that its internal controls were "not effective as of September 30, 2016, due to the aggregation of internal control deficiencies related to the implementation, design, maintenance and operating effectiveness of various transaction, process level, and monitoring controls." When this information was disclosed to the public, shares of Pattern declined in value, causing investors harm. If you wish to learn more about this lawsuit free of charge, or if you have questions regarding this notice or your rights, please contact Joon M. Khang, a prominent litigator for almost two decades, by telephone: (949) 419-3834, or by e-mail at email@example.com. This press release may constitute Attorney Advertising in some jurisdictions.
