On 20 January 2025, President Trump issued an Executive Order renaming the area known as the “Gulf of Mexico” as the “Gulf of America”. The US Interior Department formally announced the change on 24 January 2025 and US federal agencies are currently in the process of implementing the change. In this 2024 Annual Report, Woodside uses the term “Gulf of Mexico” to refer to the area in which its Shenzi, Mad Dog and Atlantis projects are located, as that term was in effect during the period covered by this report. Woodside will adopt the naming conventions required by applicable laws and regulations in relation to US waters.
