WILMINGTON, Del., April 28, 2014 /PRNewswire/ -- Andrews & Springer LLC, a boutique securities class action law firm focused on representing shareholders nationwide, is investigating potential breach of fiduciary duty claims against the Board of Directors of Questcor Pharmaceuticals, Inc. ("Questcor" or the "Company") (NASDAQ: QCOR) relating to the sale of the Company to Mallinckrodt plc (NYSE: MNK) ("Mallinckrodt"). On April 7, 2014, the two companies announced the signing of a definitive merger agreement pursuant to which Mallinckrodt will acquire Questcor in a merger valued at roughly $5.6 billion. As a result of the merger, shareholders are anticipated to receive $30 in cash and .897 shares of Mallinckrodt for each share of Questcor stock.

On February 27, 2014 and March 14, 2014 respectively, research analyst firm Citron Research published two articles asserting that the Company's primary drug, Acthar, a drug used to manage difficult-to-treat autoimmune conditions, is a "mislabeled, mis-dosed unproven drug . . . [marketed] to vulnerable, chronically ill patients." In a ten-year period, the price for a vial of Acthar has risen from $40 to $28,000. As noted by Citron, since January 2010, insiders at the Company have sold over $249 million of their stock. An investigation by the FDA is currently ongoing.

Since the announcement of the merger, the Company's stock price has fallen roughly -1.9%. Moreover, the Company disclosed today that it missed Q1 revenues by $12.71 million.
