The Company will not provide a hard copy of the Company’s annual financial report to Shareholders unless specifically requested to do so.

However, such a resolution is advisory only and does not bind the company or the directors of the company. The remuneration report sets out the Company’s remuneration arrangements for the Directors and senior management of the Company. The remuneration report is part of the directors’ report contained in the annual financial report of the Company for the financial year ending 30 June 2026. The Chair must allow a reasonable opportunity for its shareholders to ask questions about or make comments on the remuneration report at the Annual General Meeting. Voting consequences A company is required to put to its shareholders a resolution proposing the calling of another meeting of shareholders to consider the appointment of directors of the company (Spill Resolution) if, at consecutive annual general meetings, at least 25% of the votes cast on a remuneration report resolution are voted against adoption of the remuneration report and at the first of those annual general meetings a Spill Resolution was not put to vote. If required, the Spill Resolution must be put to vote at the second of those annual general meetings. If more than 50% of votes cast are in favour of the Spill Resolution, the company must convene a shareholder meeting (Spill Meeting) within 90 days of the second annual general meeting. All of the directors of the company who were in office when the directors' report (as included in the company’s annual financial report for the most recent financial year) was approved, other than the managing director of the company, will cease to hold office immediately before the end of the Spill Meeting but may stand for re-election at the Spill Meeting. Following the Spill Meeting those persons whose election or re-election as directors of the company is approved will be the directors of the company. Previous voting results At the Company’s previous annual general meeting held on 14 November 2025, the votes cast against the remuneration report considered at that annual general meeting were less than 25%. Accordingly, the Spill Resolution is not relevant for this Meeting. Resolution 1 is a non-binding Ordinary Resolution. The Chair intends to exercise all available proxies in favour of Resolution 1. If the Chair is appointed as your proxy and you have not specified the way the Chair is to vote on Resolution 1, by signing and returning the Proxy Form, you are considered to have provided the Chair with an express authorisation for the Chair to vote the proxy in accordance with the Chair's intention, even though Resolution 1 is connected directly or indirectly with the remuneration of members of the Key Management Personnel. 9 Core Lithium | 2026 Notice of Annual General Meeting Resolutions 2, 3 and 4 – Election of Directors – Paul Brown, Mark Hine and Anna Neuling General Clause 13.4 of the Constitution allows the Directors to appoint, at any time, a person to be a Director either to fill a casual vacancy or as an addition to the existing Directors, but only where the total number of Directors does not at any time exceed the maximum number specified by the Constitution. Pursuant to the Constitution and Listing Rule 14.4, any Director, other than the Managing Director, so appointed holds office only until the next annual general meeting and is then eligible for election by Shareholders but shall not be taken into account in determining the Directors who are to retire by rotation (if any) at that meeting. Mr Paul Brown, having been appointed by other Directors on 2 March 2026, in accordance with the Constitution, will retire in accordance with the Constitution and, being eligible, seeks election from Shareholders. Mr Mark Hine and Ms Anna Neuling, having been appointed by other Directors on 2 March 2026 and 24 July 2026 respectively, in accordance with the Constitution, will retire in accordance with the Constitution and Listing Rule 14.4 and being eligible, seek election from Shareholders. Resolutions 2, 3 and 4 are Ordinary Resolutions. The Chair intends to exercise all available proxies in favour of Resolutions 2, 3 and 4. Further information in relation to Mr Brown is set out below. Qualifications, experience and other material directorships Mr Brown has a successful professional career spanning over 25 years in the Australian resources industry, serving as Chief Executive Officer of Hastings Technology Metals, an Australian rare earths mining company based in Perth, prior to joining the Company in 2024. Before joining Hastings, Mr Brown spent eight years at Mineral Resources Limited, rising to the position of Chief Executive Officer Lithium and Iron Ore, where he was responsible for the safe and efficient operation of the company's iron ore and lithium operations. His mining expertise provides deep knowledge of the strategic and operational requirements of the Finniss Lithium Project. While at Mineral Resources Limited and Fortescue Ltd, Mr Brown played a vital role in delivering significant mining operations, including Solomon Hub, the Mount Marion and Wodigna lithium projects and the Wonmunna iron ore mine. Term of office Mr Brown has served as a Director since 2 March 2026 following his appointment as Chief Executive Officer (CEO) on 4 June 2024. Independence If re-elected, the Board considers that Mr Brown will not be an independent Director as he is the Company’s Managing Director. Other material information The Company conducts appropriate checks on the background and experience of candidates before their appointment to the Board. These include checks as to a person’s experience, educational qualifications, character, criminal record and bankruptcy history. The Company undertook such checks prior to the appointment of Mr Brown. Board recommendation Having received an acknowledgement from Mr Brown that he will have sufficient time to fulfil his responsibilities as a Director and having reviewed the performance of Mr Brown since his appointment to the Board and the skills, knowledge, experience and capabilities required by the Board, the Directors (other than Mr Brown) recommend that Shareholders vote in favour of this Resolution. 10 Core Lithium | 2026 Notice of Annual General Meeting Further information in relation to Mr Hine is set out below.
