The law firm of Kirby McInerney LLP announced today that a class action lawsuit has been filed in the United States District Court for the District of Maryland against Osiris Therapeutics Inc. ("Osiris" or the "Company") (NASDAQ:OSIR) on behalf of all persons or entities who acquired Osiris securities during the period from May 12, 2014 through November 16, 2015 (the "Class Period"). Pursuant to applicable law, investors have until January 22, 2016 to file a motion to be appointed as lead plaintiff in the investor lawsuit. The lawsuit alleges that throughout the Class Period, the Company materially misstated its revenues from several contracts. On November 16, 2015, the Company announced that it needed to restate revenue recognition for three contracts, resulting in decreased revenue for the first three quarters of 2015. On this news, the stock price declined from $13.99 to $10.97 per share.
