Item 1.01 Entry into a Material Definitive Agreement.

On March 16, 2018, Nabriva Therapeutics plc (the “Company”) entered into a Controlled Equity OfferingSM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co., as agent (“Cantor Fitzgerald”), pursuant to which the Company may offer and sell ordinary shares, nominal value $0.01 per share, for aggregate gross sale proceeds of up to $50,000,000 (the “Shares”) from time to time through Cantor Fitzgerald (the “Offering”).  The Company is also filing a prospectus supplement with the Securities and Exchange Commission in connection with the Offering (the “Prospectus Supplement”) under the Company’s shelf Registration Statement on Form S-3 (File No. 333-219567), which became effective on August 10, 2017 (the “Registration Statement”).

Upon delivery of a placement notice and subject to the terms and conditions of the Sales Agreement, Cantor Fitzgerald may sell the Shares by methods deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended (the “Securities Act”), including sales made directly on or through The Nasdaq Global Market (“Nasdaq”), on any other existing trading market for the Company’s ordinary shares, in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices, or by any other method permitted by law, including privately negotiated transactions, subject to the prior written consent of the Company.

The Company or Cantor Fitzgerald may suspend or terminate the offering of Shares upon notice to the other party, subject to certain conditions.  Cantor Fitzgerald will act as sales agent on a commercially reasonable efforts basis consistent with its normal trading and sales practices and applicable state and federal law, rules and regulations and the rules of Nasdaq.

The Company has agreed to pay Cantor Fitzgerald commissions for its services of acting as agent of up to 3.0% of the gross proceeds from the sale of the Shares pursuant to the Sales Agreement.  The Company has also agreed to provide Cantor Fitzgerald with customary indemnification and contribution rights.

A copy of the Sales Agreement is attached as Exhibit 1.1 hereto and is incorporated herein by reference.  The foregoing description of the material terms of the Sales Agreement does not purport to be complete and is qualified in its entirety by reference to such exhibit.

The Shares will be sold pursuant to the Registration Statement, and offerings of the Shares will be made only by means of the Prospectus Supplement.  This Current Report on Form 8-K shall not constitute an offer to sell or solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities law of such state or jurisdiction.
