Yinson Integrated Annual Report 2026

104 YINSON HOLDINGS BERHAD SUSTAINABILITY REVIEW MANAGEMENT APPROACH Yinson upholds high business standards through a strong governance and risk framework that emphasises transparency, accountability, leadership and sustainable performance. The Board oversees governance, ensuring stakeholder interests are protected through effective control systems. Our framework is supported by policies that promote integrity and sound leadership at the highest level, including our Directors’ Fit and Proper Policy, which sets clear criteria for director appointments and re-appointments to ensure they possess the requisite integrity, competence and experience. In addition, our Conflict of Interest Policy for directors and employees safeguards integrity, transparency and accountability. By setting out clear disclosure requirements and guidance on managing conflicts, it promotes objective decision-making and ensures business dealings remain impartial. With Yinson’s strong presence in Brazil, we ensure key governance policies are available in Portuguese for clarity and compliance. These include our COBE, Anti-Bribery and AntiCorruption (“ABAC”) Policy & Procedure, Whistleblowing Policy & Procedure and HLR Policy. We regularly review and update our policies to maintain high business ethics and governance standards. Our BRSC is chaired by an Independent Non-Executive Director (“INED”) and includes other INEDs and the Group CEO. It oversees our risk management, compliance and sustainability governance in accordance with its TOR. Following a review of the Group’s risk maturity and profile, the Board approved for BRSC to meet biannually instead of quarterly from FY2027, enabling more focused strategic risk discussions and optimised Board time. Oversight remains robust through escalation thresholds, interim reporting and ad-hoc briefings. Anti-Bribery & Anti-Corruption We maintain a zero-tolerance stance against bribery and corruption and support anti-corruption efforts in all jurisdictions where we operate. Following our ISO 37001:2016 recertification, the Group continued to uphold its Anti-Bribery Management System (“ABMS”) in alignment with the standard. In August 2025, Yinson Holdings Berhad (YHB) and Yinson Production Offshore Pte Ltd (YPOPL) completed Surveillance Audit 1 conducted by Bureau Veritas with no nonconformities, reaffirming the effectiveness of our anti-bribery controls. During FY2026, the Group conducted a review of its AntiBribery Management System to ensure readiness for the transition to the revised ISO 37001:2025 requirements, including strengthening its risk assessment processes and incorporating climate-related considerations into the anti-bribery risk framework. This ensures corruption risk assessments remain aligned with evolving sustainabilitylinked business models and emerging regulatory expectations. Through sustained adherence to internationally recognised standards, the Group continues to enhance its governance framework for the prevention, detection and response to bribery risks. Whistleblowing We continue to maintain an independent whistleblowing channel that provides a secure and confidential platform for stakeholders to raise concerns without fear of retaliation. Reports can be submitted via the online interface or a toll-free hotline, both supported by multilingual access. We promote whistleblowing awareness through our ABAC online training module, YNet broadcasts, posters across global offices and our corporate website. By addressing concerns effectively, we maintain integrity and build trust among employees, customers, third-parties and investors. This dedication to ethical conduct is crucial for long-term success. In FY2026, we enhanced our Whistleblowing Policy and Procedure by introducing a risk-based, tiered triage framework, which enables reports to be assessed and escalated proportionately based on severity and risk, strengthening consistency, transparency and timeliness in handling whistleblowing matters. During the year, six cases were reported through the whistleblowing channel. After investigation, five were concluded as unsubstantiated due to a lack of basis. One case in relation to a health and safety matter was found to be substantiated and has since been resolved with the appropriate corrective action taken. Training and awareness Employees receive training, supplemented by awareness campaigns, that enables them to uphold high corporate governance standards. Training is mainly delivered through our Learning Management System (LMS), Learn@Yinson, which enables self-paced learning. New hires undergo ABAC training during onboarding, while current employees receive annual refresher courses, with a 80% completion rate in FY2026. During the year, we revamped our COBE and ABAC training modules and brought its development in-house to enhance agility and ensure content remains current with evolving regulatory expectations. We also rolled out an awareness training on sanctions to strengthen understanding of regulatory obligations and cross-border compliance risks. In FY2027, we plan to enhance our training framework by introducing modules on fraud, anti-money laundering and counter-financing of terrorism. Due diligence for engagements with third-party suppliers As guided by our Dealing with Third Parties Policy and Procedure, we apply a risk-based due diligence framework to assess integrity, sanctions, regulatory and reputational risks prior to engagement. The framework supports informed decision-making and ensures that third-parties align with the Group’s ethical and compliance expectations. Screening is conducted using automated tools that enable risk profiling at onboarding, with enhanced due diligence performed where elevated risks are identified. Assessments include adverse media checks, sanctions exposure, politically
