Item 8.01 Other Events.

On April 7, 2015, Prothena Corporation plc (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Credit Suisse Securities (USA) LLC and RBC Capital Markets, LLC, as representatives of the several underwriters named therein (collectively, the “Underwriters”), pursuant to which the Underwriters agreed to subscribe for an aggregate of 3,300,000 ordinary shares of the Company, $0.01 par value per ordinary share (the “Offering”). The price to the public in this offering was $37.00 per ordinary share, and the Underwriters agreed to subscribe for such ordinary shares from the Company at a price of $34.78 per ordinary share. Under the terms of the Underwriting Agreement, the Company granted the Underwriters an option for 30 days to subscribe for up to an additional 495,000 ordinary shares.

The Offering was made under a prospectus supplement and related prospectus filed with the Securities and Exchange Commission pursuant to the Company’s effective shelf registration statement on Form S-3 (Registration No. 333-203258).

On April 13, 2015, the Offering closed and the Company completed the issuance of an aggregate of 3,300,000 ordinary shares. The Company expects to receive net proceeds from the Offering of approximately $114.2 million, after deducting the Underwriters’ discount and estimated offering expenses payable by the Company.

Pursuant to the Underwriting Agreement, the Company agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Underwriters may be required to make because of such liabilities. The Company and all of the Company’s directors and executive officers also agreed not to sell or transfer any ordinary shares held by them for 90 days after April 7, 2015 without first obtaining the written consent of the Representatives on behalf of the Underwriters, subject to certain exceptions as described in the prospectus supplement.

A copy of the Underwriting Agreement is attached as Exhibit 1.1 hereto and is incorporated herein by reference. The foregoing descriptions of the Underwriting Agreement do not purport to be complete and are qualified in their entirety by reference to such exhibit.

A copy of the opinion of A&L Goodbody relating to the validity of the ordinary shares issued in the Offering is filed herewith as Exhibit 5.1.
