In 2025, we advanced initiatives across the three pillars of Noble’s sustainability framework: Sustainable Energy, Caring for People, and Responsible Business.

We are pleased to present Noble’s 2025 Sustainability Report providing metrics and examples of our framework in action across 2025. This report is prepared with reference to the European Sustainability Reporting Standards (ESRS) in anticipation of future reporting requirements under the Corporate Sustainability Reporting Directive (CSRD). These disclosures are voluntary and forward looking, designed to help stakeholders understand what we are doing, why it matters, and how we measure progress.

Advancing our decarbonization agenda

In 2025, we continued progressing toward the carbon-intensity target, following a robust approach designed to achieve reduction by 2030. Developed through scenario modeling, technology assessments, and cross-functional collaboration, the approach translates complex, strategic decarbonization pathways into an accessible roadmap for crews and the broader organization, supporting consistent execution across our fleet.

Operationally, our Energy Management System, real-time energy dashboards, and crew-driven EnergyWise ideas help teams identify significant energy users and avoid waste in real time. To enhance confidence in our data, we completed independent verification of our 2023–2024 greenhouse gas (GHG) emissions inventory against ISO standards. We further advanced digital innovation by piloting digital optimization tools and progressing a joint industry initiative to evaluate a modular, retrofit-ready offshore CO₂ system designed to support safe drilling and interventions.

Expanding training and development

Our people remained central to our performance in 2025. Noble expanded training and development opportunities across our global workforce, including increasing access to digital learning platforms, in-person and virtual Learning Lab sessions, and NORTH training for new hires. We strengthened early-career development through immersive internships, the University of Texas Co-Innovation Challenge, and the Noble Cadet Scholarship. To support national content and long-term capability where we operate, we continued investing in local workforce development, sustaining strong growth in Guyanese crew representation in Guyana, and maintaining nearly half of local crew positions filled by Colombian nationals in Colombia.

Focusing on safety, health, and environmental performance

Safety remains the foundation of everything we do. In 2025, we further strengthened our crews’ ability to identify and respond to weak signals – the subtle indicators that conditions may be changing – so issues can be addressed before they escalate. We aligned our Management by Walking Around program with the IOGP Life-Saving Rules to reinforce consistent behaviors and expectations globally. Recognizing the unique demands of offshore work, we expanded confidential mental-health support and integrated preventive practices into daily routines to help ensure our people are healthy, focused, and prepared. We also marked a significant environmental milestone as the Noble Stanley Lafosse achieved ISO 14001 certification on its first attempt, with zero major nonconformities.

Reinforcing strong governance and transparent reporting

Operating responsibly requires strong governance and community engagement. In 2025, we enhanced governance of our charitable giving through a cross-functional Charitable Contributions Committee and a formal Charitable Contributions Policy to support transparent and consistent decision making that aligns with our priorities. We reinforced ethics and compliance by achieving nearly 100% completion of global Code of Conduct training and by expanding in-person sessions across offices and rigs. We continued to offer a multi-channel reporting system that encourages early escalation and supports non-retaliation for good-faith reporting.

Our reporting approach reflects Noble’s commitment to transparency. This Sustainability Report is informed by the principles of materiality, connectivity, comparability, and completeness from ESRS 1, and is prepared in accordance with the Global Reporting Initiative (GRI), the SASB Oil & Gas Services Standard, and the IADC ESG Reporting Guidance. It is also informed by relevant elements of the ESRS and considers potential CSRD requirements. In addition, the report reflects Noble’s ongoing preparations to align with IFRS S1 and IFRS S2, with a focus on identifying and disclosing climate-related risks and opportunities.

Noble’s sustainability efforts continue in a real-world operating environment shaped by shifting weather, rig moves, and the inherent complexity of offshore work. These dynamics sometimes mask our steady progress, but they do not diminish it. We are grateful to our employees for their commitment to our purpose, for delivering safely and efficiently, and for driving meaningful improvement across our operations.

We hope this report provides a clear view of our performance in 2025 and how our sustainability actions contribute to long-term value for our customers, communities, and stakeholders.

Looking ahead, we envision Noble continuing to advance across all dimensions of our sustainability framework – excelling in Sustainable Energy, Caring for People, and Responsible Business. By strengthening performance across these areas, we aim to deliver lasting value for our stakeholders while supporting a responsible energy future.

Our sustainability framework

Noble’s sustainability framework underpins our mission to help provide affordable energy efficiently, safely, and sustainably, and is intended to build on our longstanding customer relationships and our unique innovation capabilities to heighten positive impact.

14 material topics comprise our sustainability framework and they are structured across three pillars which each correspond to Environment, Social, Governance (ESG) elements: Sustainable Energy Future, Caring for People, and Responsible Business. Of the 14 topic areas comprising the framework, three are strategic focus areas within which efforts will be focused. These include Decarbonization, Health & Safety, and Workplace Inclusion.
