SUSTAINABILITY STATEMENT

Wah Seong Corporation Berhad Annual Report 2021 15 SUSTAINABILITY STATEMENT Materiality In 2021, Wasco commissioned an external consultant to conduct a materiality assessment. The Group appointed an impartial, external party to protect the anonymity of the respondents. This assessment is essential to the Company as it responds to the ESG issues, risks and opportunities, seen in emerging global and local trends, fundamental stakeholder interest, industry best-practice and Wasco’s overall corporate context. Stakeholder Groups Participating in the Survey Shareholders and Investors Customers Employees Vendors/ Suppliers Media Regulators and Authorities Communicating our firm position on anti-corruption and anti-bribery to all stakeholders  Employees receive a copy of the Employee Handbook, which includes anti-corruption and anti-bribery, upon joining the Company.  Each must sign an acknowledgement form and return it to the Human Resources Department.  Employees are reminded of our firm opposition to corruption during regular engagement sessions and training via iLearn  The anti-corruption policy is also communicated to suppliers, contractors, subcontractors, agents, joint venture companies and third parties. The survey asked stakeholder representatives to rate the importance they placed on 18 areas of sustainability. We asked respondents to indicate how important each criterion was, on a scale of ‘very unimportant’ (1) to ‘very important’ (5). We employed a 5-point Likert Symmetric Scale so respondents could specify their level of agreement with (3) being neutral. We discovered a natural skew in the results as each stakeh ld r group was not represented equally. Unsurprisingly, we received the most responses from our employees and the fewest from Regulators & Authorities and Media. We calculated an average score for all areas withi each stakeholder group to rectify the sample imbalance. An average rating from all eight stakeholder groups was then obtained. We also asked eight embers of our senior management team to complete the survey. Their views represented Wasco.

Wah Seong Corporation Berhad Annual Report 2021 16 The Results Scores over 3 were considered of medium importance. Stakeholder scores ranged from 3.92 to 5.00; Wasco’s between 4.02 and 4.71, indicating that all issues were material to some degree. A material to very material scale was adopted as even the lowest scores fell into the important category. The matrix is presented in the following diagram.

Responsible Procurement Our supply chain includes the supply of goods and services. It encompasses nearly 845 direct suppliers with which we spend around RM298 million per annum. Our direct suppliers are mainly locals, with only 27% being foreign. We strive to improve our supply chain’s social and ethical footprint and work with suppliers that share our values. We expect our suppliers to comply with all applicable laws and demonstrate that they have the attributes set out in our Supplier Code. We recognise the opportunity to positively impact communities by making balanced choices about sourcing the required goods and services for business operations. Our responsible procurement plan focuses on four key areas: l Upholding the ethical treatment of workers l Supporting local businesses l Encouraging participation l Assessing supply chain risk management

Wah Seong Corporation Berhad Annual Report 2021 18 We conduct quantitative and qualitative assessments of all suppliers on our Approved Vendor List every year. Our selection is based on Major and Minor Vendors categories. We examine their performance to mitigate risks and drive improvement during the review. We notify poor performing suppliers and provide corrective action or improvements. The vendor may be suspended or removed from the Approved Vendor List if they do not take the requested action or make the necessary improvements. Wasco updates the Supplier Audit Matrix following the yearly assessment. Integrity, Compliance, Assurance and Reporting Concerns Ensuring integrity and compliance is a foundational element of our culture and a business priority. We set high expectations outlined in our Principles of Business Conduct. One of the Company’s values emphasises acting with integrity and remaining professional and accountable while operating openly and transparently. Anti-Bribery and Corruption Integrity is a fundamental business philosophy and is deeply rooted in the corporate culture. Wasco adopted a zerotolerance approach against all forms of bribery and corruption, such as fraud and illegal kickbacks. Wasco’s Anti-Bribery and Corruption Policy (“ABC Policy”) communicates its comprehensive anti-corruption stand. The ABC Policy evinces a proactive commitment to addressing and mitigating corruption risks, including bribery, fraud and other corrupt acts. Wasco introduced the Anti-Bribery and Corruption Policy as part of its Anti-Bribery Management System (“ABMS”), which aligns with the requirements set out in ISO 37001:2016. Endorsed by the Board of Directors, the ABC fulfils the provisions in the Guidelines on Adequate Procedures to Section 17A (5) of the Malaysian Anti-Corruption Commission Act 2009 (“MACCA”). Coverage of ABC Directors Consultants Employees Agents Vendors Representatives Contractors Tenants Sub-contractors Business associates (including joint venture and consortium partners) Other intermediaries performing works or services, for and on-behalf of Wasco All board members and employees have accepted the Company’s integrity and delivery of the ABC Policy. They have also completed anti-corruption education and training, including bribery. An anti-bribery and corruption eLearning course was held in 2021. Employees found to have been involved in bribery are subject to disciplinary action that can lead to termination. Heads of departments and sections must ensure that all employees adhere to the ABC Policy. The Board of Directors oversees our compliance with anti-corruption policies and compliance, including bribery. Every employee is responsible for preventing and reporting instances of corruption, bribery, suspicious activity or wrongdoing which may lead to bribery using our whistleblowing channels. Wasco received no (RM0) penalties due to ethical conduct breaches such as corruption during the year. A keen understanding of corruption risk exposure is the foundation of an effective anti-corruption compliance programme. Corruption risks, including bribery, are important elements in Wasco’s risk register. This keen understanding helps the Company design effective mitigation strategies and strategically deploy resources to combat potential bribery, corruption and fraud, especially for high-risk operations.

Wah Seong Corporation Berhad Annual Report 2021 23 SUSTAINABILITY STATEMENT Facts: Nature has received significant attention for its ability to remove carbon dioxide from the atmosphere and store it in the biosphere, such as in soils, grasslands, trees and mangroves, via photosynthesis. It is also a source of carbon dioxide emissions through deforestation, land and ecosystem degradation and agricultural practices. However, the right changes to land management practices can reduce emissions and improve carbon storage. Solutions: Net-zero emissions pledges to protect the climate are coming fast and furious. We rely heavily on planting trees as it is the most significant and cost-effective way to remove CO2 from the atmosphere to tackle the climate crisis. Net-zero proposals count on finding ways for these trees to take up more carbon than they already absorb. Forests Can’t Handle Carbon on Their Own We began our tree planting programme in 2021. According to our calculations, we must plant approximately 113,700 trees to absorb 7,580 CO2e tonnes of residual emissions to achieve operational net-zero emissions by 2026, based on the assumption of 15 trees for one tonne. 2012 2013 2014 2019 2021  GHG Gas Emissions verified by Bureau Veritas  Capacity building, tracking and reporting of emissions  Inclusion of carbon footprint reduction commitment in the Corporate Sustainability Policy  Corporate Sustainability reiterates commitment to emissions reduction in line with UNSDG 13 Climate Action  Implementation of the Group Emissions Reduction Plan  Launching of Operational Net Zero Emissions Plan with target set for 2026 Achieving Operational Net Zero Emissions 2020 tCO2e Year 2021 - 2,000 4,000 6,000 8,000 10,000 12,000 14,000 16,000 2022 2023 2024 2025 2026 Residual Emissions Trees 8,841 8,399 7,979 7,580 7,580 13,940 14,674

Wah Seong Corporation Berhad Annual Report 2021 24 Managing Climate Change Risks and Opportunities Wasco’s commitment to producing in a way that helps protect people, the environment and the communities where it operates includes mitigating the risks of climate change. We recognise the devastating effects and associated short- and long-term business risks that climate change presents. Wasco has a solid commitment to addressing this issue and avoiding the impact of climate change by improving the efficiency of operations. Our climate change strategy includes working with employees and supply chain partners on energy-saving processes and a complete climate change risk assessment. Our management team, overseen by Mr. Teoh Chuen Seng, Senior Manager ESG devises strategies to manage and minimise our environmental footprint. Progress reports and proposals on energy management, climate change and pollution reduction, supported by financial indicators and Return on Investment (ROI) calculations, are presented to the Board. In 2021, strategic topics included a deep dive on decarbonisation, emerging business models in the electricity transition, resource storage opportunities and emerging climate-related risks. Climate change risk is reviewed explicitly by the Sustainability Committees. Climate-related risks and opportunities are identified, assessed and managed using Wasco’s Risk Management Framework in the same way as all other risks. The Board and senior management consider, review and monitor climaterelated risks and opportunities as part of our strategic planning process, investment decisions, and regular financial and operational performance reviews throughout the year. Wasco has integrated climate-related risk management into the company-wide risk scorecard. It is part of the foundation in formulating our business strategy, deciding on future R&D as well as technology investments. Wasco’s climate risk management process includes mitigation efforts to reduce greenhouse emissions, climate engineering and increasing knowledge of climate systems. In 2021, we invested RM356,000 on: l Mitigating climate change, including planting 30,000 trees in Maran, Pahang; and l Consultancy in reviewing our GHG Baseline Inventory. Inevitably, climate change impacts operating expenses (OPEX) and capital expenditure (CAPEX), which increases product prices. Climate change reduces efficiencies and increases operating costs (OPEX). Capital expenditure (CAPEX) is needed to retrofit existing assets to cope with new climatic conditions. We are committed to addressing the issue of climate change and improving efficiency through adaptation by adopting new and green technology in developments and implementing fuel efficiency measures. Specifically, we have adopted a tracking system for emissions, energy use, water use and waste in our manufacturing. Wasco is an active member of the Malaysian Oil & Gas Services Council (MOGSC) and continues to address climaterelated issues, specifically how it affects the Energy sector. Our role and involvement in this membership include: l Identifying pressing environmental issues in climate change, water and waste; and l Collaborating on solutions that drive improvement within Wasco and its supply chains. We contribute to driving change management through knowledge and information sharing, especially public policy and regulation. The Council also examines various opportunities, such as hydrogen technology. We continue to ensure consistency between our climate change policy and the position we advocate at trade associations of which we are members. When opinions contradict, we respond by identifying gaps and initiating a process that alerts the Company to new areas of good business practice. Consolidation method in carbon footprint calculation Operational Organisational boundary in carbon footprint calculation Accounts for 100% of GHG emissions where Wasco has the authority to implement operational policies Independent verification of operational GHG data Our process in calculating and measuring GHG is guided and verified by the MGTC.
