Fellow Shareholders:

You are invited to attend Barrick's 2026 Annual Meeting of Shareholders (the Meeting) at which you will be asked to:

• Elect nine director nominees;
• Appoint PricewaterhouseCoopers LLP as our auditor for 2026; and
• Approve our non-binding advisory vote on our approach to executive compensation.

Shareholders will also transact any other business properly brought before the Meeting.

Barrick's Board of Directors has approved the contents of this Notice and Circular and the sending of this Notice and Circular to our shareholders, each of our directors, and our auditor.

In order to facilitate engagement with shareholders, Barrick is pleased to host a virtual meeting format for this year's Meeting that shareholders may attend by way of a live webcast regardless of their geographic location. Registered shareholders, non-registered (or beneficial) shareholders, and their duly appointed proxyholders will be able to participate, ask questions, and vote in "real time" through an online portal that may be accessed at meetings.lumiconnect.com/400-059-668-044 by following the instructions set out in the Circular. Non-registered shareholders must carefully follow the procedures set out in the Circular in order to vote virtually and ask questions through the online portal. Non-registered shareholders who do not follow the procedures set out in the Circular will nonetheless be able to view a live webcast of the Meeting, but will not be able to ask questions or vote. Please refer to the section of the Circular entitled "Meeting and Voting Information" for additional details.

Your vote is important. As a shareholder, it is very important that you read this material carefully and then vote your common shares of Barrick (Barrick Shares). You are eligible to vote your Barrick Shares if you were a shareholder of record at the close of business on March 9, 2026. You may vote via the Internet webcast or by proxy. See page 5 for further instructions on how you can vote.
