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

On April 29, 2020, Nabriva Therapeutics plc (the “Company”) received written notice (the “Notice”) from The Nasdaq Stock Market LLC (“Nasdaq”) indicating that, based on the closing bid for the last 30 consecutive business days, the Company is not in compliance with the $1.00 minimum bid price requirement for continued listing on The Nasdaq Global Select Market, as set forth in Listing Rule 5450(a)(1) (the “Bid Price Rule”). The Notice does not result in the immediate delisting of the Company’s ordinary shares from The Nasdaq Global Select Market. In accordance with Listing Rule 5810(c)(3)(A), the Company has a period of 180 calendar days to regain compliance with the Bid Price Rule. However, due to recent market conditions, Nasdaq has determined to toll the compliance period for the Bid Price Rule through June 30, 2020. As a result, the compliance period for the Bid Price Rule will be reinstated on July 1, 2020 and the Company will have until December 28, 2020 (the “Compliance Date”) to regain compliance with the Bid Price Rule. To regain compliance, the closing bid price of the Company’s ordinary shares must be at least $1.00 per share for a minimum of ten consecutive business days on or before the Compliance Date.

If the Company does not regain compliance with the Bid Price Rule by the Compliance Date, the Company may be eligible for an additional 180 calendar day compliance period. To qualify, the Company would need to transfer the listing of its ordinary shares to the Nasdaq Capital Market, provided that it meets the continued listing requirement for market value of publicly held shares and all other initial listing standards, with the exception of the Bid Price Rule. To effect such a transfer, the Company would also need to pay an application fee to Nasdaq and provide written notice to Nasdaq of its intention to cure the deficiency during the additional compliance period. If the Company does not qualify for the additional compliance period or fails to regain compliance during the additional 180-day period, then Nasdaq will notify the Company of its determination to delist the Company’s ordinary shares, at which point the Company would have an opportunity to appeal the delisting determination to a Nasdaq hearing panel.

In addition to continuing to monitor the closing bid price of its ordinary shares, the Company expects to consider available options to regain compliance with the Bid Price Rule, which could include seeking to effect a reverse stock split. However, there can be no assurance that the Company will be able to regain compliance with the Bid Price Rule.
