MOCON Receives Expected Standard Filing Delinquency Letter from NASDAQ

MINNEAPOLIS, MN, August 19, 2013 — MOCON, Inc. (NASDAQ: MOCO) today announced that on August 15, 2013, it received an expected notice from the NASDAQ Stock Market indicating that MOCON is not in compliance with NASDAQ listing rules because its Form 10-Q for the quarter ended June 30, 2013 was not timely filed.  This notice has no immediate effect on the listing or trading of MOCON’s common stock on the NASDAQ Stock Market.

MOCON previously filed a Form 12b-25 Notification of Late Filing on August 9, 2013 explaining that unexpected delays in preparing financial reports using the new ERP system that it implemented during the quarter ended June 30, 2013 would cause the Form 10-Q for that quarter to be filed late.  MOCON is expeditiously addressing the issues that are delaying the preparation of these reports and accordingly anticipates it will be able to file the 10-Q for the quarter ended June 30, 2013 during the week of August 26, 2013.  MOCON does not anticipate having similar difficulties in subsequent periods.

The NASDAQ notice directs MOCON to submit a plan to regain compliance with the continuing listing requirements by October 14, 2013.  MOCON expects to address the notice by filing the Form 10-Q well before this date, thereby fully regaining compliance with the NASDAQ continued listing requirements.
