Osiris Discloses Inaccurate Prior Period Financial Statements

On November 16, 2015, Osiris Therapeutics filed its 10-Q Quarterly Report, disclosing multiple restatements in prior financial results, including three restatements made to distributor relationships. As a result of these adjustments, Osiris missed revenue targets in three of the last four quarters. Specifically, Osiris stated that it will correct the revenue recognition for three contracts, which will result in a decrease in product revenues of $1.8 million in the first quarter of 2015, a decrease in product revenue of $1.0 million in the second quarter, an increase in product revenues of $0.8 million in the third quarter of 2015, and a decrease in product revenues of $1.1 million in 2014. On this news, Osiris stock fell $3.01 per share, or about 21%, to close at $10.97 per share on November 17, 2015.
