WASHINGTON, D.C. March 2, 2018– Cohen Milstein Sellers & Toll PLLC is conducting an investigation to determine whether Quantum Corporation (“Quantum” or the “Company”) and certain of its officers and directors made false and misleading statements and/or omissions in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. 

A class action lawsuit was filed in the U.S. District Court for the Northern District of California by another law firm on behalf of purchasers of the common stock of Quantum (NYSE: QTM) between May 10, 2016 and February 7, 2018, inclusive (the “Class Period”). 

The complaint alleges that Quantum and certain of its officers and directors (“Defendants”) misrepresented and/or failed to disclose that: (1) Quantum was inappropriately recognizing certain revenues since at least April 2016; (2) the Company lacked adequate controls over accounting and financial reporting; (3) as a result the Company was subject to increased regulatory scrutiny and potential fines; and, (4) Defendants’ statements about Quantum’ business, operations, and prospects, were materially false and/or misleading and/or lacked a reasonable basis.

On November 13, 2017, Quantum announced the resignation of its CEO Jon Gacek, effective November 7, 2017, and his replacement by interim CEO Adalio Sanchez.  Quantum provided no further details on Gacek’s resignation.

On February 8, 2018, Quantum issued a press release announcing a postponement of issuing its third quarter 2017 financial results and the earnings call, both scheduled for that afternoon. The delay was due to a continuing investigation by the Company’s Audit Committee into “accounting matters and related internal controls that were raised in response to a recent inquiry by the Securities and Exchange Commission (SEC).”  The price of Quantum shares fell from $5.57 on February 7, 2018 to $3.90 on February 8. 2018.

Cohen Milstein encourages all investors who purchased Quantum common stock between May 10, 2016 and February 7, 2018, or former employees with information concerning this matter to contact the firm.
