Asset integrity and process safety To maintain safe and reliable operations, ADNOC has created operating procedures and maintenance programs to prevent incidents such as leaks and spills. We also use risk-based inspection, predictive maintenance and monitoring systems to identify and address risks across the asset life cycle. The asset integrity and process safety (AIPS) management manual, which provides a risk-based approach to asset integrity, is ISO 55001 certified. Leadership oversees AIPS risks as part of enterprise risk management. We apply best practices from the IOGP, the American Petroleum Institute (API), the Center for Chemical Process Safety (CCPS), the Energy Institute (EI) and other industry bodies. We also conduct periodic assurance reviews and independent third-party evaluations. ADNOC upholds strict well-management standards to maintain well integrity and safety. This approach includes the following: • Defined management systems and monitoring to enable us to detect and mitigate well integrity risks • Clear leadership accountability • Alignment with international standards and best practices 6 As per API classification of safety events: A Tier 1 PSE is a loss of primary containment (LOPC) with the greatest consequence. 7 A Tier 2 PSE is a LOPC with lesser consequence.

These are aligned with UAE regulations and international standards and are reviewed regularly. Road transportation ADNOC operates industrial fleets and applies controls including journey planning, driver competency, vehicle inspection and maintenance, and defensive driving training. We monitor data on exposure and driver behavior to identify risks and implement corrective actions. In 2025, ADNOC recorded approximately 625 million kilometers driven and achieved a motor vehicle crash rate of 2.7 per 100 million kilometers. We use AI-enabled technologies to improve safety, including in-vehicle monitoring systems (IVMS) and active fatigue and distraction detection (AFDD), which monitor driving behavior and detect fatigue and distraction in real time. By the end of 2025, more than 1,000 vehicles were equipped with AFDD. During 22 million kilometers of monitored travel, these vehicles recorded zero crashes. Air transportation In 2025, ADNOC transported over 609,100 passengers across offshore and onshore locations. The fleet included 15 helicopters and a flexible fixed - wing fleet (two to four aircraft based on demand). Helicopter operations accumulated 22,500 flight hours, while fixed - wing aircraft recorded over 2,400 flight hours. Operations are governed by National Aviation Authority regulations, ADNOC HSE requirements and original equipment manufacturer (OEM) and operator standards. Risk assessments and controls cover weather, aircraft integrity, landing operations, crew competency and emergency preparedness. Marine transportation ADNOC operates a marine fleet of more than 220 vessels that support offshore and logistics operations. These include mobile offshore units, marine support vessels, offshore supply vessels (both with and without dynamic positioning) and 55 deep - sea vessels. Including onboard crew, more than 4,670 personnel work across marine operations. Approximately 1,250 of those workers support deep-sea operations. Marine activities are managed through CPs covering vessel certification, crew competency, risk assessment and emergency response to manage navigational, operational and environmental risks. In 2025, we deployed an asset integrity and process safety reporting tool to support active performance monitoring. We recorded one Tier 1 6 and five Tier 2 7 process safety events (PSEs) in 2025. In all cases, we promptly activated safety protocols and emergency response procedures, provided medical attention and support where required, and investigated each event to identify root causes and implement corrective actions. 43 ADNOC Sustainability Report 2025 ADVANCING NET ZERO EMPOWERING LIVES HOW WE OPERATE SUSTAINABILITY AT ADNOC ABOUT ADNOC PROTECTING NATURE AND BIODIVERSITY KEEPING OUR PEOPLE SAFE 42
