September 2026 (Q1 FY27) Quarterly Production Report 23 October 2026 Whitehaven Coal Limited ABN 68 124 425 396 Page 1 of 9 Strong Q1 production and cost performance delivers a strong start to FY27 • Total recordable injury frequency rate (TRIFR) of 7.4 for employees and contractors for the quarter • September quarter managed ROM production of 11.0Mt, up 3% on the June quarter (up 22% on pcp1) • September quarter equity sales of produced coal of 6.0Mt, down 5% on the June quarter reflecting reduced vessel throughput from export terminal disruptions at RG Tanna and PWCS • Unit cost of coal for the quarter was at the low end of the FY27 guidance range of $132 - $147/t • Whitehaven average achieved price of A$226/t, up 2% on the June quarter (up 20% on pcp) • Net debt of ~A$1.4 billion at 30 September 2026, with the temporary impact of sales slippages and elevated inventories expected to unwind in the December quarter. QLD – Strong Q1 ROM production providing a solid start for FY27, sales to recover in Q2 • QLD managed ROM production of 5.5Mt for the September quarter, down 4% on June quarter • QLD equity sales of produced coal of 2.8Mt for the quarter, down 12% on the June quarter reflecting poor terminal performance at RG Tanna in the quarter • September quarter average price2 of A$257/t for QLD operations with 12-month average metallurgical coal realisations at 74% of the PLV HCC Index. NSW – Narrabri ROM production was strong in Q1 contributing to a good quarter for NSW • NSW managed ROM production of 5.5Mt in the September quarter, up 10% on the June quarter • NSW equity sales of produced coal of 3.2Mt for the quarter, up 2% on the June quarter • September quarter average achieved price2 of A$198/t for NSW operations with thermal coal realisations at 103% of the gC NEWC Index. Commenting on Whitehaven’s quarterly production, Paul Flynn, CEO & Managing Director said: “Whitehaven has had a strong start to FY27, with September quarter managed ROM production of 11.0Mt and equity sales of 6.0Mt. “Both our Queensland and New South Wales operations delivered good operational outcomes, with solid ROM production and unit costs at the low end of our FY27 guidance range, despite elevated diesel costs. “Customer demand remained strong and coal prices continued to strengthen during the September quarter. “Sales volumes were solid, although export terminal disruptions at both RG Tanna and PWCS resulted in sales slipping from the September quarter into the December quarter. “With stronger coal prices and the deferred and contingent payments for the Queensland acquisition nearing completion, Whitehaven is well positioned to generate stronger cash flows and increase financial flexibility over the remainder of FY27."

Whitehaven Coal Limited ABN 68 124 425 396 P +61 2 8222 1100 Page 3 of 9 Level 28, 259 George Street, Sydney NSW 2000 whitehavencoal.com.au PO Box R1113, Royal Exchange QLD Operations QLD operations delivered a solid start to FY27 with September quarter managed ROM production of 5.5Mt. This was 4% lower than the very strong June quarter and 17% higher than the September quarter last year. Managed sales of produced coal of 3.5Mt for the September quarter were down 12% on the June quarter due to reduced vessel throughput at RG Tanna (Blackwater’s loading terminal) as a result of planned and unplanned loading outages at the terminal totalling 12 days during the quarter. Closing stocks increased by 1.0Mt to 3.1Mt driven by the poor port performance. With the port now operating as normal, the increase in stocks is expected to unwind in the December quarter as vessel queues improve at RG Tanna. • Blackwater’s September quarter ROM production of 4.1Mt was in line with the June quarter delivering a strong start to FY27 and continuing the strong productivity improvements from the end of the previous financial year. Total sales from Blackwater of 2.3Mt were 13% lower than the June quarter, reflecting timing of sales as a result of port disruptions. Operational disruptions at RG Tanna during the quarter affected vessel loading, while rail deliveries continued uninterrupted, resulting in elevated inventories at port and increased vessel queues. • Daunia’s 1.4Mt of ROM production in the September quarter was down 19% on the strong June quarter but in line with plan as the box-cut in the southern domain commenced. This was a solid start to FY27, which capitalised on dry weather conditions. Daunia’s total September quarter sales were 1.2Mt, down 9% on the June quarter, with coal production, processing, sales and shipment timing closely aligned during the quarter. NSW Operations NSW operations delivered 5.5Mt of managed ROM production in the September quarter. This was a 10% improvement on the June quarter with Narrabri delivering a strong uplift in volumes quarter on quarter while open cut operations delivered solid production, in line with plan. Managed sales of produced coal of 4.0Mt were 5% higher than the June quarter, despite short-term planned and unplanned loading terminal disruptions at PWCS, which increased vessel queues and resulted in some sales slipping into the December quarter. The loader impacted by the unplanned outage has returned to operations and vessel queues are now reducing, while the planned loader outage remains on track for completion in November. Closing stocks of 2.2Mt were 23% higher than June quarter due to timing of sales. • Maules Creek’s September quarter ROM production of 2.7Mt was down 22% on the June quarter in line with planned mine sequence for the quarter. Total sales of 2.1Mt were 18% lower than the June quarter. • Narrabri’s strong ROM production of 1.9Mt in the September quarter was significantly higher than the June quarter as an uninterrupted period of production provided a strong start to FY27. The next longwall move is currently expected to commence in March 2027 and scheduled to take approximately nine weeks, during which the remaining roof support overhauls will be completed. Narrabri sales totalled 1.4Mt in the September quarter, which was a significant increase on the June quarter. • Gunnedah Open Cuts (GOC) delivered consistently in the September quarter with 0.9Mt of ROM production, which is in line with the June quarter. Vickery produced 0.6Mt and Tarrawonga 0.3Mt of ROM production in the September quarter. Sales for the quarter of 0.5Mt were relatively low, reflecting terminal disruptions and higher Narrabri volumes; sales slippage is expected to recover in the December quarter. In August, Whitehaven received approval for GOC to haul up to 4.1Mt of coal per calendar year to the Gunnedah CHPP, up from the previous limit of 3.5Mt. GOC is ramping up operations to utilise the increased haulage capacity.

In the September quarter, Whitehaven delivered equity sales of produced coal of 6.0Mt (2.8Mt from QLD and 3.2Mt from NSW), which was 5% lower than the June quarter. September quarter sales mix by revenue was 57% from metallurgical coal and 43% from thermal coal3. QLD operations achieved an average price2 of A$257/t in the September quarter, up 4% on the June quarter (up 29% on pcp). Platts PLV HCC FOB Australia Index (“PLV HCC”) averaged US$248/t in the quarter, also up 4% on the June quarter. The monthly index ranged between US$229/t and US$278/t. QLD operations realised an average price of US$184/t (74% of PLV HCC) for metallurgical coal sales in the quarter. The 12-month average realisation was 74% of PLV HCC. The September quarter sales mix comprised 58% HCC / SHCC (achieving 78% of PLV HCC), 39% PCI / SSCC (achieving 68% of PLV HCC) and 3% thermal coal. NSW operations achieved an average price2 of A$198/t in the September quarter, in line with the June quarter (up 13% on pcp). September quarter gC NEWC Index averaged US$135/t, also in line with US$136/t in the June quarter. The September quarter monthly index ranged between US$130/t and US$145/t. NSW thermal coal sales in the September quarter realised an average price of US$140/t, equivalent to 103% of gC NEWC. Note, in an increasing or decreasing index environment, Whitehaven expects to lag the PLV HCC Index for met coal price realisations and the gC NEWC for thermal coal prices realisations. Lags typically reflect pricing mechanisms based on the month of scheduled shipment or the average quarterly price for a quarter, or prices can be agreed up to three months prior to delivery. Current Market Dynamics and Near-term Outlook The PLV HCC index continued to strengthen during the September quarter, supported by improved buying interest from Chinese steel mills together with improving demand for coking coal from other markets including Japan, Europe and Korea. Supply constraints have persisted and remain a feature of the market, with restricted supply of coking coal from China’s Shanxi mining region and ongoing diesel supply constraints limiting landborne imports from Mongolia and impacting China’s coal flows. In India, growth in steelmaking capacity is increasingly evident, supporting stronger coking coal demand over time. In the near term, however, the onset of India’s monsoon season provides some moderation of demand, while favourable mining conditions across the Bowen Basin are supporting sufficient supply to meet near-term requirements ahead of the Queensland wet season. Whitehaven’s Queensland met coal portfolio remains well positioned to benefit from improving market fundamentals and supportive demand and supply dynamics. The gC NEWC Index strengthened toward the end of the September quarter as energy security concerns continued. Ongoing conflict in the Middle East and broader geopolitical uncertainty supported energy prices, with reliable and secure supply of thermal coal remaining a priority for power utilities ahead of the northern hemisphere winter. Uncertainty around Indonesian thermal coal exports also persisted following government intervention aimed at safeguarding domestic supply, and more recently accentuated by low river levels restricting barge movements in Kalimantan. This tightened the availability of lower- quality thermal coal and provided broader support for seaborne thermal coal prices, including the gC NEWC Index. While energy markets remain volatile, Whitehaven’s NSW thermal portfolio is well positioned to benefit from improvements in the gC NEWC Index and supportive market fundamentals. Longer-term Coal Market Dynamics The expected structural shortfall in global metallurgical coal production, particularly the long-term depletion of HCC from Australian producers combined with increased seaborne demand from India, is anticipated to drive higher metallurgical coal prices over the longer-term. Whitehaven’s metallurgical coal portfolio is expected to benefit from these supply constrained market dynamics. Longer-term demand for seaborne high CV thermal coal, together with a structural supply shortfall from underinvestment in new mines and depletion of existing supply, remains a driver for longer-term price support for high CV thermal coal. In developing economies, thermal coal continues to play a critical role in delivering affordable and reliable access to electricity. This focus on energy security is expected to further support longer-term demand for high-quality thermal coal. Disruptions are likely to continue to impact supply across the global energy complex for a period following cessation of Middle East tensions.

Diesel costs averaged ~$1.38/litre during the quarter, compared with the ~$1.16/litre average assumed in the midpoint of FY27 cost guidance, which factored in some moderation in diesel prices during H2 FY27. At a Group level, average royalties for the quarter were ~A$27/t (12%). Balance sheet Net debt increased by ~$0.1 billion to ~$1.4 billion at 30 September 2026. As is typically the case, there were higher cash outflows in the September quarter. Outflows included $61 million of shareholder distributions through the FY26 final dividend and share buy-back and $84 million for the Year 2 contingent payment to BMA for the Queensland acquisition. Cash inflows were also impacted by reduced port throughput at RG Tanna and PWCS, which resulted in higher vessel queues and some sales slipping into the December quarter. Working capital increases caused by 1.0Mt higher coal inventories and a build in receivables is expected to unwind through the December quarter. With the final US$100 million deferred payment to BMA due in April 2027 and the final contingent payment due in early July 2027, Whitehaven is approaching the end of the acquisition payment schedule, providing greater flexibility for future capital allocation. Payments to BMA The second contingent payment of US$58 million was paid to BMA on 2 July 2026. Based on an average realised price of US$175/t for the first two quarters of Year 3 versus the threshold price of US$134/t, the year-to-date contingent payment for the year ending 2 April 2027 (Year 3) is estimated at US$109 million, subject to third-party verification. The full year contingent payment is capped at US$350 million. The final deferred acquisition payment of US$100 million is due in April 2027, with the final contingent payment due in July 2027. These payments will complete the obligations to BMA relating to the acquisition of Daunia and Blackwater. Share buy-back and capital returns During the September quarter, Whitehaven continued its on-market share buy-back, with 1.8 million shares bought back for a total of $14 million. The share buy-back program is a key component of Whitehaven’s Capital Allocation Framework, which includes targeted shareholder returns of 40-60% of underlying Group NPAT4. The split between fully franked dividends and share buy-backs considers franking benefits, composition of share register, the extent buy-backs are value creating, and points in the cycle.

The timing of development plans and capital expenditure will reflect competing opportunities for capital and market conditions. During the September quarter, A$1.6 million of development expenditure was spent on the Vickery and Winchester South development projects. This included activities to support mine planning, infrastructure development, and exploration. An additional A$2.4 million was spent on exploration activities across both NSW and QLD operations for coal quality and geotechnical analysis. Vickery Extension Project Early mining at Vickery continues to progress following commencement of the box cut in FY24. Development of the full-scale Vickery project has received all required Government approvals, but remains subject to Board approval of FID, which will be considered at the appropriate time. Winchester South Metallurgical Coal Project The Queensland Department of Environment, Tourism, Science and Innovation (DETSI) has approved the Winchester South Coal Mine Draft Environmental Authority, and the Commonwealth EPBC approval process is progressing. Objections have been received against the Winchester South Draft Environmental Approval and Mining Lease Applications and referred to Queensland Land Court, with closing submissions heard in December 2025. Judgment has been reserved. Whitehaven is continuing to work on the Feasibility Studies including synergies with Daunia coal mine.
