Woodside Acting CEO Liz Westcott said the company delivered strongly against its 2025 business objectives, outperforming production guidance while advancing key growth projects. “We achieved record annual production of 198.8 million barrels of oil equivalent in 2025. This performance was driven by sustained plateau production at Sangomar through late October and Pluto LNG operating at 100% reliability for the second half of the year. “In recent days we marked a special milestone for the Scarborough Energy Project with the safe arrival of the floating production unit at the field and commencement of hook-up activities. The project was 94% complete at the end of the year and remains on budget and on target for first LNG cargo in Q4 2026. “In late December first production was achieved at Beaumont New Ammonia. Final project commissioning will continue through early 2026 ahead of project completion and Woodside assuming operational control. Production will commence with conventional ammonia with lower-carbon ammonia planned for 2H 2026. “Woodside has finalised agreements with leading global customers to supply conventional ammonia from Beaumont. These deliveries will commence in 2026 and continue through year-end, under contracts that reflect prevailing market prices. “We also continued to progress our major development pipeline, with the three‑train foundation phase of the Louisiana LNG Project reaching 22% completion at quarter‑end, targeting first LNG in 2029. “During the period Woodside entered a strategic partnership with leading US gas infrastructure company Williams, selling a 10% interest in the Louisiana LNG HoldCo and an 80% operating interest in PipelineCo, further demonstrating the quality of the project. Under the transaction, Williams will contribute approximately $1.9 billion in capital expenditure and assume offtake obligations for 10% of Louisiana LNG’s produced volumes. “The Trion Project in Mexico was 50% complete at the end of the year, with hull assembly and installation of all critical equipment on the topside’s modules now completed. “Also during the quarter, we took a final investment decision to develop the North West Shelf Project’s Greater Western Flank Phase 4. The project extends production from the North West Shelf by around one year and delivers an internal rate of return of approximately 30%.5 “During the period we signed long term LNG sale and purchase agreements with SK Gas International and BOTAŞ, supplied from Woodside's global portfolio including LALNG, evidencing the value customers place on our product. “Woodside strengthened its position in the Gulf of America as the successful bidder on eight exploration blocks.6 “We are looking forward to first LNG from Scarborough in the fourth quarter of this year. Our 2026 volume guidance of 172 - 186 MMboe reflects planned down time at Pluto as we prepare the facility to begin processing Scarborough gas and for first LNG cargo in Q4 2026. “Woodside continues to execute our strategy as outlined at our recent Capital Markets Day. The executive team and I remain focused on safely delivering our operations and projects while maintaining rigorous cost management during the CEO transition period." 2 | Fourth quarter report for period ended 31 December 2025 5 Figures are Woodside share, 50% interest.

for illustrative purposes only. It should not be relied on as, and is not necessarily, a reliable indicator of future performance, including future security prices. Other important information All figures are Woodside share for the quarter ending 31 December 2025, unless otherwise stated. All references to dollars, cents or $ in this report are to US currency, unless otherwise stated. References to “Woodside” may be references to Woodside Energy Group Ltd and/or its applicable subsidiaries (as the context requires). Notes to petroleum reserves and resources 1. The petroleum reserve estimates are quoted as at the effective date of 31 December 2025, net Woodside share. US investors should refer to “Additional information for US investors concerning reserves and resources estimates” below. 2. All numbers are internal estimates produced by Woodside. Estimates of reserves and contingent resources should be regarded only as estimates that may change over time as additional information becomes available. 3. For offshore oil and gas projects, the reference point is defined as the outlet of the floating production storage and offloading facility (FPSO) or platform. 4. For onshore gas projects the reference point is defined as the outlet of the downstream (onshore) gas processing facility. 5. ‘Reserves’ are estimated quantities of petroleum that have been demonstrated to be producible from known accumulations in which the company has a material interest from a given date forward, at commercial rates, under presently anticipated production methods, operating conditions, prices, and costs. Woodside reports reserves inclusive of all fuel consumed in operations. Woodside estimates and reports its proved reserves in accordance with SEC regulations which are also compliant with the 2018 Society of Petroleum Engineers (SPE)/World Petroleum Council (WPC)/American Association of Petroleum Geologists (AAPG)/Society of Petroleum Evaluation Engineers (SPEE) Petroleum Resources Management System (PRMS) (SPE-PRMS) guidelines. SEC-compliant proved reserves estimates use a more restrictive, rules-based approach and are generally lower than estimates prepared solely in accordance with SPE-PRMS guidelines due to, among other things, the requirement to use commodity prices based on the average of first of month prices during the 12-month period in the reporting company’s fiscal year. Woodside estimates and reports its proved plus probable reserves in accordance with SPE- PRMS guidelines which are not compliant with SEC regulations. 6. Assessment of the economic value in support of an SPE-PRMS (2018) reserves and resources classification, uses Woodside Portfolio Economic Assumptions (Woodside PEAs). The Woodside PEAs are reviewed on an annual basis, or more often if required. The review is based on historical data and forecast estimates for economic variables such as product prices and exchange rates. The Woodside PEAs are approved by the Woodside Board. Specific contractual arrangements for individual projects are also taken into account. 7. Woodside uses both deterministic and probabilistic methods for the estimation of reserves and contingent resources at the field and project levels. All proved reserves estimates have been estimated using deterministic methods and reported on a net interest basis in accordance with the SEC regulations and have been determined in accordance with SEC Rule 4-10(a) of Regulation S-X. 8. ‘MMboe’ means millions (106) of barrels of oil equivalent. Natural gas volumes are converted to oil equivalent volumes via a constant conversion factor, which for Woodside is 5.7 Bcf of dry gas per 1 MMboe. All volumes are reported at standard oilfield conditions of 14.696 psi (101.325 kPa) and 60 degrees Fahrenheit (15.56 degrees Celsius). 9. ‘Proved reserves’ are those quantities of crude oil, condensate, natural gas and NGLs that, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward from known reservoirs and under existing economic conditions, operating methods, operating contracts, and government regulations. Proved reserves are estimated and reported on a net interest basis in accordance with the SEC regulations and have been determined in accordance with SEC Rule 4-10(a) of Regulation S-X. 10. ‘Undeveloped reserves’ are those reserves for which wells and facilities have not been installed or executed but are expected to be recovered through future significant investments. 11. ‘Probable reserves’ are those reserves which analysis of geological and engineering data suggests are more likely than not to be recoverable. Proved plus probable reserves represent the best estimate of recoverable quantities. Where probabilistic methods are used, there is at least a 50% probability that the actual quantities recovered will equal or exceed the sum of estimated proved plus probable reserves. Proved plus probable reserves are estimated and reported in accordance with SPE-PRMS guidelines and are not compliant with SEC regulations. 12. The estimates of petroleum reserves and contingent resources are based on and fairly represent information and supporting documentation prepared by, or under the supervision of, Mr Benjamin Ziker, Woodside’s Vice President 23 | Fourth quarter report for period ended 31 December 2025

Reserves and Subsurface, who is a full-time employee of the company and a member of the Society of Petroleum Engineers. The reserves and resources estimates included in this announcement are issued with the prior written consent of Mr Ziker. Mr Ziker’s qualifications include a Bachelor of Science (Chemical Engineering) from Rice University (Houston, Texas, USA) and 27 years of relevant experience. Additional information for US investors concerning resource estimates Woodside is an Australian company with securities listed on the Australian Securities Exchange and the New York Stock Exchange. As noted above, Woodside estimates and reports its proved reserves in accordance with SEC regulations, which are also compliant with SPE-PRMS guidelines, and estimates and reports its proved plus probable reserves and 2C contingent resources in accordance with SPE-PRMS guidelines. Woodside reports all petroleum resource estimates using definitions consistent with SPE-PRMS. The SEC prohibits oil and gas companies, in their filings with the SEC, from disclosing estimates of oil or gas resources other than ‘reserves’ (as that term is defined by the SEC). In this announcement, Woodside includes estimates of quantities of oil and gas using certain terms, such as ‘proved plus probable (2P) reserves’, ‘best estimate (2C) contingent resources’, ‘reserves and contingent resources’, ‘proved plus probable’, ‘developed and undeveloped’, ‘probable developed’, ‘probable undeveloped’, ‘contingent resources’ or other descriptions of volumes of reserves, which terms include quantities of oil and gas that may not meet the SEC’s definitions of proved, probable and possible reserves, and which the SEC’s guidelines strictly prohibit Woodside from including in filings with the SEC. These types of estimates do not represent, and are not intended to represent, any category of reserves based on SEC definitions, and may differ from and may not be comparable to the same or similarly-named measures used by other companies. These estimates are by their nature more speculative than estimates of proved reserves and would require substantial capital spending over a significant number of years to implement recovery, and accordingly are subject to substantially greater risk of not being recovered by Woodside. In addition, actual locations drilled and quantities that may be ultimately recovered from Woodside’s properties may differ substantially. Woodside has made no commitment to drill, and likely will not drill, all drilling locations that have been attributable to these quantities. The Reserves Statement presenting Woodside’s proved oil and gas reserves in accordance with the regulations of the SEC is filed with the SEC as part of Woodside’s annual report on Form 20-F. US investors are urged to consider closely the disclosures in Woodside’s most recent Annual Report on Form 20-F filed with the SEC and available on the Woodside website at https:// www.woodside.com/investors/reports-investor-briefings and its other filings with the SEC, which are available at www.sec.gov.
