Yancoal Australia Ltd ($YAL) acquired its 80% Kestrel interest on 1 October 2026. It funded the US$1.85 billion upfront consideration, subject to adjustments, with cash and borrowing on a US$1.2 billion facility. A separate US$200 million working-capital facility remained undrawn. Completion notice.

We would start any fresh valuation with the borrowing. Investors can assess whether Kestrel is worth its purchase price, but they cannot treat the cash spent on it as still available to shareholders. The mine and the money used to buy it have to appear in the same calculation.

What shareholders have bought

Yancoal’s April announcement reported Kestrel’s 2025 saleable production at 5.9 million tonnes on a whole-mine basis. Multiplying by the acquired 80% gives 4.72 million tonnes attributable to Yancoal as a historical illustration, before any change in output. That is neither 2026 guidance nor a full year of production belonging to the buyer. Yancoal recognises its share from 1 October. Acquisition announcement, completion notice.

The company estimated that the deal would raise metallurgical coal to 22% of its mix on a pro-forma 2025 basis. Metallurgical coal is used in steelmaking; thermal coal is principally a fuel. The transaction therefore changes the business investors are valuing, rather than simply adding more of the same tonnes. April announcement.

The strongest case for the purchase is that Yancoal can earn an attractive return from an operating asset while broadening its customer exposure. We would give that argument serious consideration. Buying established production could be preferable to spending years developing a mine that may never reach its planned output.

Diversification still needs a price test. Steelmaking exposure could help if thermal coal weakens, but we would also test a scenario in which both markets soften together. Shareholders need enough operating cash after royalties, maintenance, development spending and interest to justify the capital committed.

June’s cash is a dated starting point

Yancoal reported A$2.094 billion of cash at 30 June. Its first-half cash-flow statement shows A$462 million from operations, A$254 million paid for property and equipment, and A$23 million of lease repayments. Interest paid was already in operating cash flow. The desk calculation below uses those actual cash movements. Half-year accounts, cash-flow statement.

Desk residual before acquisitions and shareholder dividends185

The A$185 million is a historical six-month residual, not Yancoal’s own free-cash-flow definition or a forecast dividend. It excludes investing dividends and acquisition payments. The company paid A$161 million of shareholder dividends during the half. It also lowered its full-year capital guidance partly because spending moved into 2027. Doubling the residual would ignore that timing. Half-year accounts, cash flows and outlook.

A generous cash balance can support an acquisition. Once management spends it, the investment question changes from how much cash shareholders could receive to what the acquired business can earn.

The settlement details still matter

The notice omits the actual draw and closing cash. Settlement deducts the US$40 million deposit; further borrowing is expected to retire Kestrel group debt. Treating the full facility limit as debt already drawn would be another error. Completion notice, footnotes 2–3.

Our next valuation needs a reconciliation from the dated cash balance through subsequent trading, dividends, settlement, debt refinancing and fees. We would include leases consistently when comparing peers, translate currencies at a stated date and account for the minority interest when using consolidated earnings. Until that reconciliation is available, a precise post-deal enterprise value would suggest more certainty than the disclosures support.

Vendors can receive up to US$550 million if benchmark coal exceeds US$225 per tonne in the first five years. The payment is contingent. Completion notice.

In a strong-price scenario, shareholders should model the seller payment alongside the additional mine cash. In a weak-price scenario, they should test how comfortably the enlarged group can service its borrowing. The earn-out may share some upside with the vendors; it does not remove the buyer’s downside.

We would become more positive if Kestrel produces dependable cash after its capital requirements and Yancoal reduces acquisition debt without relying on unusually high coal prices. A larger production total alone would not settle the value question. The companion Peabody cash review examines why that distinction matters when screening coal shares.
