Any statements in this presentation about future expectations, plans and prospects for Nabriva, including but not limited to statements about the development of Nabriva’s product candidates, such as plans for the design, conduct and timelines of Nabriva’s ongoing Phase 3 clinical trial of lefamulin for CABP, the clinical utility of lefamulin for CABP and Nabriva’s plans for filing of regulatory approvals and efforts to bring lefamulin to market, the development of lefamulin for additional indications, the development of additional formulations of lefamulin, plans to pursue research and development of other product candidates, the sufficiency of Nabriva’s existing cash resources and other statements containing the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “target,” “potential,” “likely,” “will,” “would,” “could,” “should,” “continue,” and similar expressions, constitute forward-looking statements within the meaning of The Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors, including: the uncertainties inherent in the initiation and conduct of clinical trials, availability and timing of data from clinical trials, whether results of early clinical trials or trials in different disease indications will be indicative of the results of ongoing or future trials, whether results of Nabriva’s first Phase 3 clinical trial of lefamulin will be indicative of the results for its second Phase 3 clinical trial of lefamulin, uncertainties associated with regulatory review of clinical trials and applications for marketing approvals, the availability or commercial potential of product candidates including lefamulin for use as a first-line empiric monotherapy for the treatment of moderate to severe CABP, the sufficiency of cash resources and need for additional financing and such other important factors as are set forth under the caption “Risk Factors” in Nabriva’s annual and quarterly reports on file with the U.S. Securities and Exchange Commission. In addition, the forward-looking statements included in this press release represent Nabriva’s views as of the date of this release. Nabriva anticipates that subsequent events and developments will cause its views to change.

LEAP 1 Phase 3 Clinical Trial Highlights Lefamulin is the first anti-bacterial agent of a new class of antibiotics with favorable Phase 3 data in CABP in more than 15 years Lefamulin’s efficacy data - in our first trial treating adults with CABP - was comparable to a gold standard therapy Lefamulin showed a favorable tolerability profile with no unexpected safety signals or evidence of off-target effects Lefamulin IV, with an option to switch to oral administration, met all primary FDA and EMA endpoints of non-inferiority compared to moxifloxacin (±linezolid)

Lefamulin Addresses the Factors that Increasingly Influence Treatment Choices for CABP *10 days in clinical trials for confirmed MRSA CABP patients 5-7 days IV/PO Monotherapy for Most* Patients Novel Mechanism of Action CABP Targeted Spectrum of Activity Stewardship Guidelines recommend use of targeted antibiotics, not broad spectrum, and shortest effective treatment duration Resistance to many current antibiotics is rising and increases the need for antibiotics with novel mechanisms of action LEFAMULIN IV & Oral Formulations allow the flexibility to switch from any IV treatment and to discharge the patients earlier or avoid hospitalization
