SHAREHOLDER ALERT: Class Period Expanded in Class

STEVENSON, Md., May 29, 2014 (GLOBE NEWSWIRE) -- The securities litigation law firm of Brower Piven, A Professional Corporation, announces that a class action lawsuit has been commenced in the United States District Court for the District of Colorado on behalf of purchasers of Advanced Emissions Solutions, Inc. ("Advanced Emissions" or the "Company") (Nasdaq: ADES ) securities expanding the class period to include March 14, 2013 through April 23, 2014 (the "Class Period"), and reminds investors that they have until June 30, 2014 to seek appointment as lead plaintiff.

If you have suffered a loss from investment in Advanced Emissions securities purchased on or after March 14, 2013 and held through the revelation of negative information during and/or at the end of the Class Period, and would like to learn more about this lawsuit and your ability to participate as a lead plaintiff, without cost or financial obligation, click here: http://www.browerpiven.com/securitiesfraudcases.html .

You may also request more information by contacting Brower Piven either by email at hoffman@browerpiven.com or by telephone at (410) 415-6616. Attorneys at Brower Piven together have more than a century of experience litigating securities and other class action cases.

No class has yet been certified in the above action. Members of the Class will be represented by the lead plaintiff and counsel chosen by the lead plaintiff. If you wish to choose counsel to represent you and the Class, you must apply to be appointed lead plaintiff no later than June 30, 2014 and be selected by the Court. The lead plaintiff will direct the litigation and participate in important decisions including whether to accept a settlement and how much of a settlement to accept for the Class in the action. The lead plaintiff will be selected from among applicants claiming the largest loss from investment in Company units during the Class Period.

The complaint accuses the defendants of violations of the Securities Exchange Act of 1934 by virtue of the defendants' failure to disclose during the Class Period that the Company was employing improper accounting practices, particularly with respect to its method for recognizing revenue for its Emission Control business segment contracts. According to the complaint, following the Company's March 13, 2014 announcement that the Company was reviewing its accounting practices, particularly its methods of recognizing revenue for its Emission Control business segment contracts, and that the Company expects the result of the review to likely result in increased operating losses, the value of Advanced Emissions shares declined significantly.

If you choose to retain counsel, you may retain Brower Piven without financial obligation or cost to you, or you may retain other counsel of your choice. You need take no action at this time to be a member of the class.
