Materiality Assessment
Plan B assesses materiality and sustainability issues annually, considering both internal and external factors that encompass risk and impact aspects, as well as stakeholders' expectations.
Internal factors include the impact of economic, social, and environmental risks and opportunities in operations, the value chain and the preservation of the company's core values. External factors include global trends, opinions of external stakeholders, and sustainability issues in the same industry. The assessment employs the double materiality principle, which considers the impact of environmental, social, and governance (ESG) factors on the company, as well as the effects of the company's activities on ESG stakeholders. The assessment criteria are based on the company's risk management standards to ensure alignment with future company risk assessments. The company ranks key sustainability issues based on their overall impact on the company.

The Board of Directors and the Sustainability and Governance Committee oversee the evaluation and ensure its alignment with the Global Reporting Initiative (GRI) Standards 2021 for reporting material topics:
1. Understanding the organizational context
PLANB's understanding of the organization's context involves reviewing the company's business operations, sustainability context, and relationships with stakeholders throughout the value chain. Additionally, the company analyzes global trends and standards in the industry to identify relevant sustainability issues that affect the business and its stakeholders.
The factors used to identify key sustainability issues include:
- Global Reporting Initiative or GRI Standards
- S&P Global ESG Indices
- MSCI Index
- SET THSI Index
- Global trends in the industry
2. Identifying the impacts and potential consequences of materiality issues
PLANB places great importance on conducting comprehensive impact assessments to reinforce sustainable operations. The company regularly engages in discussions with internal departments and external stakeholders to identify, analyze, and evaluate both actual and potential impacts arising from issues that are material to the company, stakeholders, the economy, the environment, and human rights. These assessments cover both positive and negative impacts. This process enables the company to manage risks effectively, uncover new opportunities, and develop strategic plans that align with stakeholder expectations, ultimately fostering shared value and long-term sustainable growth.
3. Assessing the materiality impacts issues
PLANB places strong emphasis on assessing the materiality of identified impacts through a comprehensive evaluation process that considers the severity, scope, likelihood of occurrence, and the company’s capacity or limitations in remediating those impacts. The company focuses on evaluating both positive and negative impacts to appropriately prioritize issues, which in turn supports the development of effective management strategies aligned with sustainable development goals and the creation of long-term shared value with stakeholders.
4. Prioritizing the materiality impact for reporting
PLANB prioritizes the importance of sustainability issues based on two criteria:
- Importance to stakeholders and
- Importance of business impacts in economic, social, and environmental contexts
These issues are ranked as high, medium, and low priority. The assessment results of sustainability issues are presented to the Corporate Governance and Sustainability Committee and validated by the Management Board to review and verify the accuracy of the prioritization of sustainability issues. This ensures alignment with the company's strategy and sustainability context.
