Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

On November 10, 2016, MISONIX, INC. (the “Company”) received a deficiency letter from The Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company, as a result of not filing its Quarterly Report on Form 10-Q (the “10-Q”) by November 9, 2016 and disclosing that the Company will not be able to file the 10-Q within the five-day extension period provided in Rule 12b-25(b) under the Securities Exchange Act of 1934, as amended, together with its prior and ongoing failure to timely file its Annual Report on Form 10-K, was not in compliance with Listing Rule 5250(c)(1) of the Nasdaq Listing Rules (the “Rules”) for continued listing.

Under the Rules, the Company had until November 14, 2016 to submit a plan to Nasdaq to regain compliance and if Nasdaq accepts such plan, Nasdaq can grant an exception until March 13, 2017 to regain compliance. If Nasdaq does not accept the Company’s plan, the Company has the opportunity to appeal such decision to a Nasdaq Hearings Panel. The Company submitted a plan to regain compliance to Nasdaq on November 14, 2016.

At this time, this notification has no effect on the listing of the Company’s common stock on The Nasdaq Global Market.

The Company issued a press release on November 15, 2016 with respect to the foregoing which is attached hereto as Exhibit 99.1.
