Materiality Assessment

Materiality Assessment Process

        The Materiality Assessment serves as a mechanism to identify and evaluate economic, social, and environmental factors that impact BAM operations. This is achieved by studying national and international sustainability principles, guidelines, and standards, alongside the expectations and concerns of relevant stakeholders. In 2025, the Company identified its material topics by adopting the Global Reporting Initiative (GRI) framework and relevant SASB indicators. The assessment evaluates business impacts across five key dimensions: Economic, Governance, Environmental, Social, and Human Rights. 

Key Steps in Materiality Assessment Process

Understand the Organization’s Context

        BAM reviewed the material sustainability topics from 2024 along with current internal and external data relevant to its business context. The process includes an analysis of the corporate vision, mission, policies, business relationships, Sustainable Development Goals (SDGs), and industry trends at both national and international levels. Additionally, the Company integrates insights regarding the expectations, concerns, and impacts identified by key stakeholder groups. This comprehensive review led to the identification of 2025 Material Sustainability Topics relating to the Company’s context across Economic, Governance, Environmental, Social, and Human Rights dimensions.

Identification of Actual and Potential Impacts

        BAM identifies and evaluates significant impacts arising from business operations on all stakeholder groups through a structured prioritization process. This involves identifying both actual and potential impacts, encompassing both positive and negative effects. These impacts are assessed across the dimensions of the Economy, Environment, Society, and Human Rights throughout the entire value chain. By conducting comprehensive due diligence, the Company has established a set of Material Topics that cover five core dimensions: Economic, Governance, Environmental, Social, and Human Rights.

Assessment of the Significance of Impacts

        BAM assesses the significance of sustainability topics by entering identified actual and potential impacts into a prioritization process. This process utilizes the Double Materiality approach to determine the material topics most relevant to the organization’s context, based on both impact materiality and financial materiality criteria.

Prioritizing the Most Significant Impacts for Reporting

        BAM presents the identified sustainability topics to senior management for review and verification of completeness. This ensures that the material topics remain aligned with the business context, the impacts generated by business processes throughout the value chain, and the concerns of all stakeholder groups. In 2025, Senior Management approved 16 material sustainability topics (Material Topics) for the Company. These topics cover the dimensions of the Economy, Governance, Environment, Society, and Human Rights. Furthermore, these topics were presented to and formally approved by the Board of Directors, with details as follows:

The 2025 Material Topics are derived from a materiality assessment process based on the principle of Impact Materiality. This report marks the fourth edition produced to disclose the sustainability performance of BAM for the 2025 reporting cycle. BAM utilizes these high-priority material topics as the primary framework for defining and developing the corporate sustainability strategy. This approach ensures the driving of balanced growth and long-term sustainability.
