Item 8.01. Other Events

On September 27, 2016 and September 28, 2016, respectively, Misonix, Inc. (the “Company”) contacted the Securities and Exchange Commission (“SEC”) and the U.S. Department of Justice (“DOJ”) to voluntarily inform both agencies that the Company may have had knowledge of certain business practices of the independent Chinese entity that distributes its products in China, which practices raise questions under the Foreign Corrupt Practices Act (“FCPA”).

The Audit Committee of the Board of Directors of the Company engaged outside counsel to conduct an internal investigation to review these and other matters. The internal investigation is ongoing. The Company has no current information derived from the investigation to date or otherwise to suggest that its previously reported financial statements and results are incorrect in any material respect.

The Company intends to cooperate fully with the DOJ and SEC as the investigation continues. At this stage, the Company is unable to predict what, if any, action the DOJ or the SEC may take or what, if any, penalties or remedial measures these agencies may seek. Any determination that the Company’s operations or activities are not in compliance with existing laws or regulations could result in the imposition of fines, civil and criminal penalties, equitable remedies, including profit disgorgement, and injunctive relief.
