 of the factors described above, and that the ability to continue to grant equity compensation is vital to our ability to continue to attract and retain employees in the highly competitive labor markets in which we compete, our Board has determined that the size of the share reserve under the Amended 2018 LTIP, as proposed to be augmented pursuant to the Amendment, is reasonable and appropriate at this time.

A summary of the principal provisions of the Amended 2018 LTIP is set forth below. This summary is qualified by reference to the Amendment, which is attached as Appendix A to this Proxy Statement; the Prothena Corporation plc 2018 Long Term Incentive Plan, which is available as Exhibit 10.1 of the Company’s Current Report on Form 8-K filed with the SEC on May 18, 2018; and the First through Fifth Amendments to the Prothena Corporation plc 2018 Long Term Incentive Plan, which are available as Exhibit 10.11(b) of the Company’s Annual Report on Form 10-K filed with the SEC on February 27, 2025.

| Administration |

The Amended 2018 LTIP may be administered by our Board, its Compensation Committee, or such other committee of the Board (the “Committee”) as is designated by the Board. To the extent required to comply with Rule 16b-3 of the Exchange Act, it is intended that each member of the Committee will be a "non-employee director" within the meaning of Rule 16b-3. The Committee or our Board may delegate its powers under the Amended 2018 LTIP to one or more members of the Board or one or more directors, officers, or managers of the Company or any subsidiary, provided that no officer may be delegated the authority to grant awards to or amend awards held by senior executives of the Company who are subject to Section 16 of the Exchange Act or any

officer or director to whom authority to grant or amend awards has been delegated. The Board, the Committee, or a delegate thereof, as applicable, are referred to herein as the "plan administrator."

The plan administrator has the authority to administer the Amended 2018 LTIP, including the power to determine eligibility, the types and sizes of awards, the price and vesting schedule of awards, the methods for settling awards, the method of payment for any exercise or purchase price, any rules and regulations the plan administrator deems necessary to administer the Amended 2018 LTIP
