GRI reporting principles Accuracy Balance Clarity Comparability Completeness Sustainability Context Timeliness Verifiability Reporting boundaries This report covers calendar year 2025 (January 1 to December 31) and draws from the review of our 2025 double materiality assessment (DMA). The reporting boundary for sustainability performance data encompasses all ADNOC subsidiaries, where we hold responsibility for setting and enforcing standards. It covers all aspects of our operations where we maintain 100% operational control. The scope of this report includes ADNOC’s listed companies whose equity stakes were transferred to XRG P.J.S.C as part of an internal administrative restructuring, where ADNOC retains ultimate ownership and control through its 100% shareholding in XRG P.J.S.C (ADNOC Distribution, ADNOC Drilling, ADNOC Gas and ADNOC Logistics & Services). The reporting boundary does not currently extend to other XRG investments or portfolio companies. It excludes Borouge Pte joint venture activities outside the UAE and all Fertiglobe operations, both within and outside the UAE 1 . Where a KPI follows a different boundary, the boundary is noted in detail in the ESG data index. Financial figures are reported in US dollars ($) and UAE dirhams (AED).
