| **Item 5.07.** | **Submission of Matters to a Vote of Security Holders.**  |

On October 24, 2025, Mural Oncology plc, a public limited company organized under the laws of Ireland (the "Company"), held a special meeting of shareholders convened pursuant to section 450(1) of the Irish Companies Act 2014 (the "Scheme Meeting") and an extraordinary general meeting of shareholders (the "EGM"), in each case relating to the proposed acquisition (the "Acquisition") of the entire issued and to be issued share capital of the Company by XRA 5 Corp. ("Sub"), a wholly-owned subsidiary of XOMA Royalty Corporation ("XOMA Royalty"). The Acquisition is to be effected by means of a "scheme of arrangement" under Irish law (the "Scheme of Arrangement"), pursuant to the Transaction Agreement, dated August 20, 2025, among the Company, XOMA Royalty and Sub.

Below are the voting results for the proposals submitted to the Company's shareholders for a vote at the Scheme Meeting and the EGM.

#### Scheme Meeting
**PROPOSAL 1**: That the Scheme in its original form or with or subject to any modification(s), addition(s) or condition(s) approved or imposed by the Irish High Court be agreed to.

The Company's shareholders approved Proposal 1 at the Scheme Meeting with the following voting results:

---

| | | | |
|:---|:---|:---|:---|
| **For** | **Against** | **Abstain** | **Broker Non-Votes** |
|  10,103,706 | 81,149 | 52,031 |  |

---

In addition, of the 9 shareholders of record voting on the proposal, 8 shareholders, or 99.20% of those voting, voted in favor of the proposal and 1 shareholder, or 0.79% of those voting, voted against the proposal*.* The votes cast in favor of Proposal 1 represented a majority in number of the shareholders of record present and voting, either in person or by proxy, and at least 75% of the value of the shares voted at the meeting, either in person or by proxy.

**PROPOSAL 2**: The proposal to approve any motion by the Chair to adjourn the Scheme Meeting, or any adjournments thereof, to another time and place if necessary or appropriate to solicit additional proxies if there are insufficient votes at the time of the Scheme Meeting to approve the Scheme of Arrangement was not presented to the shareholders at the Scheme Meeting, as there were sufficient votes to approve Proposal 1.

#### Extraordinary General Meeting
**PROPOSAL 1**: To approve the Scheme of Arrangement in its original form or with or subject to any modification(s), addition(s) or condition(s) approved or imposed by the Irish High Court and authorize the directors of the Company to take all such actions as they consider necessary or appropriate for carrying the Scheme of Arrangement into effect.

------

The Company's shareholders approved Proposal 1 at the EGM with the following voting results:

---

| | | | |
|:---|:---|:---|:---|
| **For** | **Against** | **Abstain** | **Broker Non-Votes** |
|  10,607,228 | 89435 | 13056 |  |

---

**PROPOSAL 2**: To approve an amendment to the articles of association of the Company so that any ordinary shares of the Company that are issued on or after the voting record time to persons other than Sub and/or its nominees will either be subject to the terms of the Scheme or will be immediately and automatically acquired by Sub and/or its nominee(s) for the scheme consideration.

The Company's shareholders approved Proposal 2 at the EGM with the following voting results:

---

| | | | |
|:---|:---|:---|:---|

The disclosure of a "dealing" in "relevant securities" by a person to whom Rule 8.3(b) applies must be made by no later than 3:30 p.m. (U.S. Eastern Time) on the "business day" following the date of the relevant "dealing".

*All "dealings" in "relevant securities" of the Company by a bidder, or by any party acting in concert with a bidder, must also be disclosed by no later than 12 noon (U.S. Eastern Time) on the "business day" following the date of the relevant "dealing".*

*A disclosure table, giving details of the companies in whose "relevant securities" opening position disclosures and dealing disclosures should be made, can be found on the Irish Takeover Panel's website at www.irishtakeoverpanel.ie.*

In particular, a person will be treated as having an "interest" by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.*
