The Role of the Board

Nomination and Appointment of Directors

The Board is committed to promoting long-term value and is accountable to shareholders for the performance of AMO.

The AMO Board Charter contains information about the respective roles and responsibilities of the Board and management, including those matters expressly reserved to the board and those delegated to management. The AMO Constitution formally governs the Board’s conduct, including in Board meetings.

New directors will be recommended to the Board by the Nomination and Remuneration Committee. The Board will assess the suitability of new directors against criteria which include experience, ability to exercise independent judgment, professional skills, potential conflicts and the requirement for independence.

Appropriate checks are made before appointing any director (or senior executive) or putting forward someone for election as a director.

Board Committees

New directors must complete the new director induction program which includes meeting with senior executives and being given a comprehensive briefing on AMO’s operations, its strategies, the nature of its business and various segments, its financial position and performance and its operational and risk management.

The Board has established two committees to assist it in discharging its role and responsibilities:

• Audit and Risk Management Committee

• Remuneration and Nomination Committee.

The role and responsibilities of the committees are set out in each Board Committee Charter and are summarised in this corporate governance statement.

AMO provides shareholders information about each candidate standing for election or re-election as a director that the Board considers necessary for shareholders to make a fully informed decision. Director biographies can also be found on AMO’s website.

The AMO Board Committee Charters can be found on the AMO website at

Director Election and Board Renewal

The Board, in conjunction with the Remuneration and Nomination Committee, regularly reviews it succession plans. At the Company’s Annual General Meeting, onethird of the directors (rounded down) must retire from office and are eligible to stand for re-election. If a director (other than the MD) at the conclusion of the AGM will have been in office for 3 or more years and for 3 or more annual general meetings since last elected to office, they must retire from office. A retiring Director is eligible for re-election.

Responsibilities of Management

The Board has delegated matters to management, subject to financial and other limits.

The Managing Director (MD) has been delegated authority for matters that are not reserved to the Board or delegated to Board Committees. The MD ensures the Board is provided with accurate and sufficient information on the AMO’s operations and achievement towards strategic goals of AMO.

Tom Amos will retire by rotation in 2025 and will stand for re-election at the 2025 AGM.

The MD is supported by the Chief Operating Officer (COO) and other executives who regularly attend and present at Board meetings.

The Company Secretary reports directly to the Board through the Chairman and is accessible to all directors. The Company Secretary’s role, in respect of matters relating to the proper functioning of the Board, is outlined in the AMO Board Charter.

Diversity

AMO’s Board and workforce are comprised of individuals with a range of skills, backgrounds, and experiences. AMO values diversity and inclusion and recognises the organisational capabilities and business performance these bring.

AMO has adopted a Diversity Policy which describes how AMO promotes diversity and recognises diversity to include gender, age, ethnicity and cultural backgrounds, among other personal factors.

The Board’s Remuneration and Nomination Committee sets measurable objectives for achieving gender diversity and assesses the objectives and the company’s progress towards achieving them on an annual basis.

The current gender target for Board membership is 20% women. The gender target for senior executives is 40% women and for the whole organisation is 25% women – these two targets and the actual gender splits reported below are reflective of the fact AMO largely operates in what has traditionally been a male dominated sector. For non-industry technically trained staff however the gender target is 50%.

AMO discloses its performance against gender equality indicators in its Annual Report to the Workplace Gender Equality Agency.

The AMO Diversity Policy can be found on the AMO website at

Performance Assessments

Chairman

The Chairman undertakes a regular performance evaluation for the board, its committees, and directors. . The review of the Chairman’s role is conducted by the Chair of the Audit and Risk Management Committee after obtaining feedback from each individual director.

The most recent performance review was conducted in September 2024 and was supported by a confidential survey completed by each director and senior executive management.

Performance assessments for senior executives are the responsibility of the MD. The Board is responsible for assessing the performance of the MD. Assessment of the MD and senior executives occur as part of an annual review process.

Assessments consist of formal meetings to discuss performance against set KPIs which are based on company performance targets and vary according to the roles and responsibilities of the executive. At the same time, these KPIs are aligned to reflect the common corporate goals such as growth in earnings and shareholders' wealth, and achievement of working capital targets.

Performance evaluations took place during the year in accordance with the process described above.

The Chairman of AMO, Peter Wallace, is an independent, non-executive director. Mr Wallace was appointed as a director in February 2000 and was elected as Chairman in October 2002.

The Chairman’s role is to lead the Board and to represent the views of the Board publicly and to AMOs shareholders. His responsibilities include chairing Board meetings and facilitating open and effective communication at those meetings, including with management.

The roles of the Chairman and MD are separate and are not performed by the same person.

Director Skills and Experience

Collectively, the AMO Board has extensive industry experience that bring to the Board their specific skills for the company to achieve its strategic, operational and compliance objectives.

Their suitability to the directorship has been determined primarily based on their ability to deliver outcomes in accordance with the company’s short and longer-term objectives and therefore deliver value to shareholders.

The AMO Board does not presently have a formal skills matrix, however all Board members are expected to be able to demonstrate the following attributes:

Director Independence and tenure

AMO recognises that having a majority of independent directors helps to ensure that the decisions of the Board reflect the best interests of AMO and its shareholders generally, and that those decisions are not biased towards the interest of management or any other group. AMO also considers that having a majority of independent directors supports the Board to challenge and hold management to account.

In assessing whether a director is considered to be independent, the AMO Board has taken a view that independence extends to non-executive directors with less than 10% of issued capital, where that director is not the major shareholder, and where no ongoing services are being provided to the Company by the director or related entities.

On this basis, 3 out of 5 directors are “independent”. At the date of signing the Directors’ report, the Board comprises three independent directors, (Mr Peter Wallace, Mr Tom Amos and Mrs Janine Rolfe) and two non-independent directors (Mr Peter Amos and Mr Santo Carlini).

AMO has not adopted a limit on director tenure. The length of service of each director is as follows: Mr Peter Wallace (25 years); Mr Peter Amos (42 years); Mr Thomas Amos (27 years); Mr Santo Carlini (6 years) and Mrs Janine Rolfe (2 years).

Regardless of independence, all directors are expected to bring a constructive judgement to bear in Board deliberations.

Conflicts of Interest

Directors are required to disclose all interests that may conflict with their duties. If a director has a material personal interest in a matter being considered by the Board, they must not be present during the consideration of that matter or vote on the matter (unless approved by other directors who do not have a material personal interest in the matter).

Access to Information and advice

Directors have unrestricted access to all staff and all relevant records of AMO they consider necessary to fulfil their obligations (including the external auditor without management present). They also have the right to seek explanations and additional information from management and auditors.

Directors are also entitled, with the approval of the Chairman, to obtain independent professional advice at AMO’s expense relating to their role as an AMO director.

Instil a culture of acting lawfully, ethically and responsibly

AMO is committed to conducting business in an open and accountable way. We believe that lawful, ethical,

The Code applies to all employees within the company from the Board, through management to all other staff.

The Code encourages all staff and other stakeholders to report any breaches of the code to the Chairman of the Board, who is required to ensure all such matters are investigated and reported.

The Code of Conduct is supported by more detailed policies setting out the philosophy of the company in relation to its various stakeholders.

Integrity of Financial Reporting

Before it approves the financial statements for the halfyear and full year, the Board receives a statement from the MD and Chief Operating Officer (COO) consistent with the requirements of the Corporations Act 2001. These statements are made after the MD and COO receive attestations from executives regarding their respective areas of responsibility. The Board also receives a statement from the MD and COO that AMO’s risk management and internal control systems are operating effectively for the management of material business risks.

AMO provides copies of all announcements (not just material market announcements) to Directors promptly after they have been released on the market announcements platform.
