EXPLANATORY MEMORANDUM

This Explanatory Memorandum has been prepared to provide information which the Directors believe to be material to Shareholders in deciding whether to pass the Resolutions.

FINANCIAL STATEMENTS AND REPORTS

In accordance with the Constitution, the business of the Meeting will include receipt and consideration of the annual financial report of the Company for the financial year ended 31 December 2025 together with the declaration of the directors, the directors’ report, the Remuneration Report, and the auditor’s report.

The Company will not provide a hard copy of the Company’s annual financial report to Shareholders unless specifically requested to do so. The Company’s annual financial report is available on its website at www.brookside-energy.com.au.

RESOLUTION 1 – ADOPTION OF REMUNERATION REPORT (NON-BINDING RESOLUTION) AND RESOLUTION 2 – CONDITIONAL SPILL RESOLUTION (CONDITIONAL RESOLUTION)

2.1 General

The Corporations Act requires that at a listed company’s annual general meeting, a resolution that the remuneration report be adopted must be put to the shareholders. 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 a financial year.

The chair of the meeting must allow a reasonable opportunity for its shareholders to ask questions about or make comments on the remuneration report at the annual general meeting.

Under changes to the Corporations Act which came into effect on 1 July 2011, 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.

The Board notes that the Company received a ‘first strike’ in relation to the Remuneration Report following the 2024 annual general meeting (Previous Meeting).

The Board considers that the Company’s remuneration arrangements for FY2025, and as proposed for FY2026, are appropriate and reasonable having regard to the Company’s size, operational scale and complexity, prevailing market practice among comparable exploration and production companies, and the Company’s continued focus on aligning remuneration outcomes with operational performance, capital discipline and long-term Shareholder value.

2.2 Previous voting results

At the Previous Meeting the votes cast against the 2024 remuneration report considered at that meeting were greater than 25%, which constitutes a ‘first strike’ for the purposes of the Corporations Act. Of the votes cast at the Previous Meeting, 52.56% (or 14,642,298 votes) were cast for the adoption of the 2024 remuneration report and 47.44% (or 13,214,606 votes) were cast against it.

2.3 Conditional Spill Resolution (Resolution 2)

This Resolution is a conditional resolution and will only be put to Shareholders if at least 25% of the votes cast on Resolution 1 to adopt the 2025 Remuneration Report are cast against its adoption. If fewer than 25% of the votes cast are cast against its adoption, then there will be no ‘second strike’ and Resolution 2 will not be put to Shareholders.

If Resolution 2 is put to Shareholders, it will be considered as an ordinary resolution.

Messrs Michael Fry, Richard Homsany, Christopher Robertson and Christopher Weatherl, as non-executive Directors who remain in office at the time of the Spill Meeting (in the event Resolution 2 is put to Shareholders and carried as an ordinary resolution) will cease to hold office at the end of the Spill Meeting unless they are willing to stand for re-election and are re-elected at the Spill Meeting. As the Managing Director, Mr David Prentice is not subject to the Spill Resolution and will not cease to hold office, or be required to stand for re-election, at the Spill Meeting (if applicable).

The Board considers the following factors to be relevant to a Shareholder’s decision on how to vote on Resolution 2 if it is put to Shareholders at the Meeting:

The current Board has the skills and experience to provide effective oversight to the Company and to represent Shareholders.
The Director fees are on par with the general market for small cap oil and gas explorers.
Convening a Spill Meeting would cause significant disruption, uncertainty and cost to the Company, which the Board does not consider would be in the best interests of the Company or its Shareholders.

If you do not want a Spill Meeting to take place, you should vote against Resolution 2. If you want a Spill Meeting to take place, you should vote for Resolution 2.

2.4 Voting consequences

If Resolution 2 is put to Shareholders and is passed, a Spill Meeting must be held within 90 days of the passing of Resolution 2. If Resolution 2 is put to Shareholders and is not passed, the Company will not be required to hold a Spill Meeting.

2.5 Proxy voting restrictions

Shareholders appointing a proxy for Resolution 1 and Resolution 2 (if applicable) should note the following:

Proxy	Directions given	No directions given
Key Management Personnel^{1}	Vote as directed	Unable to vote^{3}
Chair^{2}	Vote as directed	Able to vote at discretion of Proxy^{4}
Other	Vote as directed	Able to vote at discretion of Proxy

Notes:

Refers to Key Management Personnel (other than the Chair) whose remuneration details are included in the Remuneration Report, or a Closely Related Party of such a member.
Refers to the Chair (where he/she is also a member of the Key Management Personnel whose remuneration details are included in the Remuneration Report), or a Closely Related Party of such a member).
Undirected proxies granted to these persons will not be voted and will not be counted in calculating the required majority if a poll is called on this Resolution.
The Proxy Form notes it is the Chair’s intention to vote all undirected proxies against Resolution 2, if it is put to Shareholders at the Meeting.

2.6 Board Recommendation

The Board recommends that Shareholders vote in favour of Resolution 1.

If Resolution 2 is put to Shareholders, the Board recommends that Shareholders vote against Resolution 2.

3. RESOLUTION 3 – RE-ELECTION OF DIRECTOR – MICHAEL FRY

3.1 General

ASX Listing Rule 14.5 provides that an entity which has directors must hold an election of directors at each annual general meeting.

The Constitution sets out the requirements for determining which Directors are to retire by rotation at an annual general meeting.

Mr Michael Fry, who has served as a director since 20 April 2004, retires by rotation and seeks re-election.

3.2 Qualifications and experience

Mr Fry holds a Bachelor of Commerce degree from the University of Western Australia and is a past member of the Australian Stock Exchange. Mr Fry has extensive corporate and

commercial experience, financial and capital market knowledge, and a background in corporate treasury management.

3.3 Independence

If re-elected the Board considers Mr Fry will be an independent Director.

3.4 Board Recommendation

The Directors support the re-election of Mr Fry and recommend that Shareholders vote in favour of Resolution 3.

4. RESOLUTION 4 – ELECTION OF DIRECTOR – CHRISTOPHER WEATHERL

4.1 General

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 exceed the maximum number specified by the Constitution.

Pursuant to the Constitution and ASX Listing Rule 14.4, any Director so appointed holds office only until the next following annual general meeting and is then eligible for election by Shareholders.

Mr Christopher Weatherl was appointed by the Board on 20 August 2025 and so retires in accordance with the Constitution and ASX Listing Rule 14.4 and, being eligible, seeks election at the Meeting.

If Resolution 4 is passed, Mr Christopher Weatherl will be re-elected as a Director. If Resolution 4 is not passed, Mr Christopher Weatherl will cease to act as a Director.

4.2 Qualifications and experience

Mr Weatherl is a Petroleum Engineer and highly experienced upstream oil and gas executive with more than 25 years of commercial, technical, operational, and leadership experience across multiple major U.S. and international basins. Mr Weatherl brings a deep understanding of U.S. shale business and a proven track record of delivering efficient, high-margin growth. His appointment is strongly aligned with Brookside’s strategy to unlock value from its high quality acreage in the SWISH Play, located in the southern Anadarko Basin, Oklahoma.

4.3 Independence

If elected the Board considers Mr Weatherl will be an independent Director.

4.4 Directors’ Recommendation

The Directors support the election of Mr Weatherl and recommend that Shareholders vote in favour of Resolution 4.

5. RESOLUTION 5 – RENEWAL OF PROPORTIONAL TAKEOVER PROVISIONS

5.1 Background

The Constitution contains proportional takeover provisions requiring Shareholders to approve any takeover offer for only a proportion of each Shareholder’s Shares (Rule 36).

These provisions are designed to assist Shareholders to receive proper value for their Shares if a proportional takeover bid is made for the Company.

In accordance with the Corporations Act and the Constitution, the proportional takeover provisions expire three years from their adoption or, if renewed, from the date of renewal.

The Company last renewed the proportional takeover provisions in Rule 36 of its Constitution at its annual general meeting on 26 May 2023. Accordingly, Rule 36 of the Constitution will cease to apply on 26 May 2026 if Shareholders do not approve the renewal of those provisions under this Resolution 5.

If renewed, the proportional takeover provisions will continue to apply on the same terms as the provisions which currently exist in the Constitution and will have effect for a period of three years, commencing on 29 May 2026. The proportional takeover provisions are set out in full in Annexure A to this Notice.

5.2 Effect

If a proportional takeover bid is made, the Directors must:

(a) Convene a general meeting no less than 14 days before the end of the bid period; and
(b) Allow Shareholders to vote on a resolution to approve the proportional takeover bid.

The bidder and its associates are not allowed to vote on that resolution.

If the resolution is rejected, binding acceptances are required to be rescinded, and all unaccepted offers and offers failing to result in binding contracts are taken to have been withdrawn.

If the bid is approved, the transfers resulting from the bid may be registered provided they comply with other provisions of the Corporations Act and the Constitution.

If no resolution is voted on by the above deadline, a resolution approving the bid is taken to have been passed.

The proportional takeover provisions do not apply to full takeover bids and will only apply until 29 May 2029, unless again renewed by Shareholders.

5.3 Reasons for renewing proportional takeover provisions

As a proportional takeover bid involves an offer for only a proportion of each Shareholder’s Shares, a bidder may acquire control of the Company:

(a) without Shareholders having the chance to sell all their Shares, leaving them as part of a minority interest in the Company; and
(b) without payment of an adequate control premium.

The Board considers that the proportional takeover provisions should be renewed as they lessen the risk of a bidder obtaining control without adequately compensating existing Shareholders as they allow Shareholders to decide collectively whether a proportional takeover bid is acceptable and appropriately priced.

5.4 Advantages and disadvantages

Advantages

Renewing the proportional takeover provisions provides Shareholders:

the right to decide whether a proportional takeover bid should proceed;
protection from being locked in as a minority Shareholder;
increased bargaining power; and
the view of majority of Shareholders which may assist individual Shareholders to decide whether to accept or reject an offer under proportional takeover bid.

Disadvantages

Renewing the proportional takeover provisions may:

discourage proportional takeover bids;
reduce Shareholders’ opportunities to sell Shares at a premium;
restrict the ability of individual Shareholders to deal with their Shares as they see fit; and
reduce the likelihood of a proportional takeover bid succeeding.

The Board considers that the potential advantages for Shareholders of the proportional takeover approval provisions outweigh the potential disadvantages.

5.5 Knowledge of acquisition proposals

As at the date of this Notice, no Director is aware of any proposal by any person to acquire, or to increase the extent of, a substantial interest in the Company.

5.6 Directors’ Recommendation

The Directors unanimously recommend the Shareholders vote in favour of Resolution 5.
