If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)


  (a) The reasons described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;

  (c) The accountant's statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.








State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.


As previously disclosed in the Current Report on Form 8-K filed by Nabriva Therapeutics plc (the “Company”) with the U.S. Securities and Exchange Commission (“SEC”) on January 9, 2023, after an assessment of the Company’s strategic options, the Board of Directors of the Company (the “Board”) approved a plan to preserve the Company’s cash to adequately fund an orderly wind down of the Company’s operations (the “Cash Preservation Plan”).


As part of the Cash Preservation Plan, the Board determined to terminate all of the Company’s employees not deemed necessary to execute an orderly wind down of the Company’s operations. The Company largely completed its planned workforce reduction in the first quarter of 2023, which significantly reduced the number of persons employed within the Company’s finance and accounting functions. As a result of the reduction in staffing, the Company has been unable, without unreasonable effort or expense, to compile the information necessary to complete its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2023 (the “Quarterly Report”) by its due date (May 15, 2023). The Company anticipates that it will file the Quarterly Report no later than the fifth calendar day following the prescribed due date.

If the answer is no, identify report(s).


  þ Yes ¨ No


(3)     Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?


  ¨ Yes þ No


If so: attach an explanation of the anticipated change, both narratively and quantitatively, and if appropriate, state the reasons why a reasonable estimate of the results cannot be made.
