September Quarter Operating Results

For the three months ended 30 September 2026, managed run-of-mine production totalled 11.0 million tonnes, up 3% on the June quarter and 22% on the prior corresponding period. Equity sales of produced coal were 6.0 million tonnes, 5% lower than in the June quarter. Whitehaven reported that disruptions at the RG Tanna and Port Waratah export terminals reduced vessel throughput, shifting some shipments from the September to the December quarter. Production growth therefore did not translate into an equivalent increase in completed sales during the period.

Queensland managed run-of-mine output was 5.5 million tonnes, down 4% quarter on quarter, and equity sales were 2.8 million tonnes, down 12%. New South Wales managed production was also 5.5 million tonnes, but rose 10% quarter on quarter, with equity sales of 3.2 million tonnes, up 2%.

Pricing, Costs and Balance Sheet

Whitehaven’s average achieved coal price in the September quarter was AUD 226 per tonne, increasing 2% from the June quarter. The Queensland operations achieved an average of AUD 257 per tonne, compared with AUD 198 per tonne in New South Wales. The company indicated that its quarterly unit cost of coal was at the lower end of the FY27 guidance range of AUD 132–147 per tonne. Realised prices and unit operating costs are different measures, and neither alone establishes operating profit because other expenses and volumes affect earnings.

At 30 September 2026, Whitehaven Coal (ASX:WHC) reported net debt of approximately AUD 1.4 billion. Management linked part of the quarter-end debt and inventory position to delayed export shipments and expected some of those timing effects to reverse as vessels departed in the December quarter. That expectation is conditional on recovery in terminal throughput and the conversion of inventory into sales. Changes in customer payment timing, Capital Expenditure and coal prices could also influence the subsequent cash result.

Export Constraints and FY27 Monitoring

The company’s next Quarterly Report is scheduled for January 2027. Important operating questions are whether the deferred September-quarter coal shipments are delivered, whether the Queensland terminals return to expected throughput and how realised prices behave across both coal products. Whitehaven Coal (ASX:WHC) also remains exposed to diesel costs, geological conditions, safety performance and mine scheduling. A temporary Backlog of product can affect Working Capital even when run-of-mine production remains within operational plans.

Comparing FY27 quarters requires keeping the period definitions consistent. Quarterly production reflects coal extracted, equity sales capture shipped volumes attributed to Whitehaven, and the average achieved price reflects the product mix sold.

Key Insights

Whitehaven Coal (ASX:WHC) increased managed production in the September 2026 quarter, while export disruptions reduced equity sales and contributed to inventories. Average realised pricing improved from June and unit costs were at the lower end of guidance. The December quarter will test whether sales deferred by port constraints convert into shipments and cash receipts.
