The Complaint alleges that during the Class Period, Advisory made materially false and/or misleading statements, and/or failed to disclose, that there were severe 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. Following this news, Advisory's stock price dropped materially, which caused investors harm.
