NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON June 5, 2025

Dear Stockholder:

You are cordially invited to attend the 2025 Annual Meeting of Stockholders of Kura Oncology, Inc., a Delaware corporation, to be held on Thursday, June 5, 2025, at 8:30 a.m. Pacific Time (the “Annual Meeting”). The Annual Meeting is being held for the following purposes:

To elect the three nominees for Class II director named in the accompanying proxy statement to serve for three-year terms until the 2028 Annual Meeting of Stockholders.

To ratify the appointment by the Audit Committee of the Board of Directors of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2025.

To approve, on an advisory basis, the compensation of our named executive officers, as disclosed in the proxy statement.

To approve an amendment to our Amended and Restated 2014 Equity Incentive Plan.

To conduct any other business properly brought before the meeting.

These items of business are more fully described in the Proxy Statement accompanying this Notice.

Our Board of Directors has fixed the record date for the Annual Meeting for April 7, 2025. Only stockholders of record at the close of business on that date may vote at the Annual Meeting or any adjournment or postponement thereof.

This year’s Annual Meeting will be held virtually through a live webcast. You will be able to attend the Annual Meeting, submit questions and vote during the live webcast by visiting www.proxydocs.com/KURA and entering the control number included in your Notice of Internet Availability of Proxy Materials, proxy card or in the instructions that you received via email. Please refer to the additional logistical details and recommendations in the accompanying proxy statement. The webcast will start at 8:30 a.m. Pacific Time on Thursday, June 5, 2025. You will not be able to attend the Annual Meeting in person. We may resume holding in-person annual meetings in the future.

Your vote is extremely important regardless of the number of shares you own. Whether or not you expect to attend the Annual Meeting, we urge you to cast your vote as soon as possible. You may vote your shares via the internet or via a toll-free telephone number by following the instructions on the Notice of Internet Availability of Proxy Materials. In addition, if you received paper copies of the proxy materials by mail, you can also vote by mail by following the instructions on the proxy card. Submitting a proxy card will not prevent you from attending the Annual Meeting and voting at the Annual Meeting, if you so desire. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the Annual Meeting, you must obtain from the record holder a proxy issued in your name.

The Notice of 2025 Annual Meeting of Stockholders, Proxy Statement and 2024 Annual Report on Form 10-K are available at the following website: www.proxydocs.com/KURA.
