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

On June 5, 2023, OpGen, Inc. (the “Company”) received written notice from The Nasdaq Stock Market LLC (“Nasdaq”) that the Company’s common stock failed to maintain a minimum bid price of $1.00 per share over the prior 30 consecutive business days as required by Nasdaq Listing Rule 5550(a)(2). In accordance with Nasdaq’s Listing Rules, the Company has 180 calendar days to regain compliance with Nasdaq’s minimum bid price requirement. If the Company does not regain compliance within this 180-day period, the Company may be eligible to seek an additional compliance period of 180 calendar days if the Company meets the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, with the exception of the bid price requirement, if the Company provides written notice to Nasdaq of its intent to cure the deficiency during this second compliance period.
