Glancy Prongay & Murray LLP (“GPM”) announces that a class action lawsuit has been filed on behalf of investors who purchased The Advisory Board Company (“Advisory Board” or the “Company”) (NASDAQ: ABCO) securities between January 21, 2015 and February 23, 2016, inclusive (the “Class Period”). Advisory Board investors have until October 2, 2017 to file a lead plaintiff motion. To obtain information or participate in the class action, please visit the Advisory Board page on our website at www.glancylaw.com/case/advisory-board-company.

The Complaint filed in this class action alleges that during the Class Period, Advisory Board made materially false and/or misleading statements, and/or failed to disclose that there were critical integration problems associated with the Company’s acquisition of Royall & Company and, as a consequence of these integration problems, the Company had no basis to increase the revenue guidance for Royall during the Class Period.

On January 9, 2015, Advisory Board completed its acquisition of Royall & Company. Then on February 23, 2016, Advisory Board announced a net loss of $101.8 million for the quarter ended December 31, 2015, primarily attributable to an impairment charge of $95.7 million (and later increased to $99.1 million) to Royall’s goodwill.

On this news, the Company’s stock price fell approximately 27% or $9.79 per share to close at $26.50 on February 24, 2016.
