Item 4.01  Changes in Registrant’s Certifying Accountant.

(a) Dismissal of Independent Registered Public Accounting Firm

On May 24, 2017 the Audit Committee (the “Audit Committee”) of the Supervisory Board of Nabriva Therapeutics AG (the “Company”) dismissed PwC Wirtschaftsprüfung GmbH (“PwC”) as the Company’s independent registered public accounting firm.

PwC’s reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2016 and 2015 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles, except that PwC’s audit report dated March 24, 2017 on the December 31, 2016 consolidated financial statements contained an explanatory paragraph stating that the Company will require additional financing to fund future operations and may be required to reduce planned expenditures.

During the fiscal years ended December 31, 2016 and 2015 and the subsequent interim period through May 24, 2017, there were no (1) disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope and procedure, which disagreements, if not resolved to PwC’s satisfaction, would have caused PwC to make reference to the subject matter of the disagreement in connection with reports for such years; or (2) reportable events (as described in Item 304(a)(i)(v) of Regulation S-K).

The Company provided PwC with a copy of the disclosures it is making in this Current Report on Form 8-K and requested from PwC a letter addressed to the Securities and Exchange Commission indicating whether it agrees with such disclosures. A copy of PwC’s letter, dated May 31, 2017, is attached as Exhibit 16.1 to this Form 8-K.

(b) Engagement of Independent Registered Public Accounting Firm

On May 24, 2017, the Audit Committee also approved the engagement of KPMG LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2017. During the fiscal years ended December 31, 2016 and 2015 and the subsequent interim period through March 31, 2017, the Company did not consult with KPMG LLP regarding any of the matters or events set forth in Item 304(a)(2) of Regulation S-K.
