Key Highlights

• In its Quarterly Report released on 23 October, Whitehaven said managed run-of-mine production was 11.0 million tonnes.

• That was up 3% on the June quarter and up 22% on the prior corresponding period.

• Queensland contributed 5.5 million tonnes, down 4% on the June quarter, while New South Wales also produced 5.5 million tonnes, up 10%.

• Equity sales of produced coal were 6.0 million tonnes, down 5%.

How did Whitehaven Coal (ASX:WHC) start its 2027 financial year, and what does it mean for the miner? The company reported record managed production for the September quarter but sold less coal than it mined, because port disruptions held back shipments. That has left stockpiles higher, which management expects to unwind in the December quarter, so delivery against full-year guidance is the central question.

What Whitehaven does

Whitehaven is an Australian coal producer with two distinct Earnings streams. In Queensland it operates metallurgical, or steelmaking, coal mines acquired from BHP Mitsubishi Alliance (BMA). In New South Wales it mines thermal coal, which is sold mainly for power generation.

Revenue depends on volumes shipped, the prices achieved and how those compare with benchmarks. Metallurgical sales are measured against the PLV hard coking coal index, thermal sales against the gC Newcastle index. Costs, including royalties, diesel and port charges, set the margin.

The September 2026 quarter

In its quarterly report released on 23 October, Whitehaven said managed run-of-mine production was 11.0 million tonnes. That was up 3% on the June quarter and up 22% on the prior corresponding period. Queensland contributed 5.5 million tonnes, down 4% on the June quarter, while New South Wales also produced 5.5 million tonnes, up 10%.

Equity sales of produced coal were 6.0 million tonnes, down 5%. Queensland sales fell 12% to 2.8 million tonnes because of poor terminal performance at RG Tanna, while New South Wales sales rose 2% to 3.2 million tonnes. Disruptions at the Newcastle terminal operator PWCS were also cited.

The average achieved price was A$226 a tonne, up 2% on the June quarter and up 20% on a year earlier. Queensland averaged A$257 a tonne and New South Wales A$198 a tonne. Over twelve months, metallurgical realisations were 74% of the PLV index and thermal realisations were 103% of the Newcastle index.

Unit costs were at the low end of the FY27 guidance range of A$132 to A$147 a tonne, although the chief executive flagged elevated diesel costs as a pressure.

Full-year FY26 results

For the year to 30 June 2026, announced on 19 August, Whitehaven reported Revenue of $5,401 million, down 7%, and underlying EBITDA of $1,250 million, down 8%. Underlying net profit after tax was $227 million, down 29%, while statutory profit was $385 million, down 41% and including $158 million of adjustments.

The final Dividend was 6.0 cents per share, fully franked, taking the full-year dividend to 10 cents. A buy-back of about $47 million was run over the second half, within up to $159 million of Capital returns for the year.

Managed production was 40.3 million tonnes, up 3%, split almost evenly between Queensland and New South Wales. Equity sales of produced coal were 26.0 million tonnes, down 2%. The average achieved price was A$202 a tonne and unit costs excluding royalties were A$132 a tonne, down from A$139.

Balance sheet and the BMA payments

Net Debt was $1,327 million at 30 June 2026, up from $634 million a year earlier, with Liquidity of $959 million. By 30 September net debt was about A$1.4 billion. The increase reflects payments for the Queensland acquisition: the second US$500 million deferred payment was made in April 2026.

Remaining obligations are a final US$100 million deferred payment due in early April 2027 and a final coal-price contingent payment due in early July 2027. Management has said the arrangements end in April 2027, after which the acquired Assets are free of acquisition-related payments. It expects that to give more flexibility for capital returns and project investment.

An April 2026 refinancing is expected to save roughly $50 million to $55 million of interest annually. About $14 million of shares were bought back during the September quarter, and the on-market buy-back continues.

Guidance and market conditions

FY27 guidance, reaffirmed in October, is managed production of 38.0 to 41.0 million tonnes and equity coal sales of 23.9 to 26.0 million tonnes. Managed sales are guided at 30.4 to 33.0 million tonnes and Capital Expenditure at $390 million to $490 million.

On markets, the company noted that PLV hard coking coal traded around US$215 to US$235 a tonne at the start of FY27, and that the Newcastle thermal benchmark averaged about US$130 a tonne in July 2026.

Competitively, Whitehaven benefits from scale, a mix of steelmaking and thermal coal, and cost control that has kept unit costs inside guidance.

Risks and what to watch

Coal prices are volatile and depend on steel output, power Demand and Supply from competing exporters. Whitehaven sells in US dollars while reporting in Australian dollars, so exchange rates feed through to earnings.

Operational risks include port reliability. Repeated terminal disruptions can delay revenue even when mines perform, and stockpiles must be shipped for production gains to show up in cash flow. Fuel costs, weather and mine geology also affect unit costs.

Longer-term risks include royalties and regulation, approvals for new mines, and the policy and investor attitudes towards fossil fuels that can affect access to finance, insurance and customers. Development work continues at the Vickery and Winchester South projects, with spending dependent on market conditions and project competitiveness.
