BHP used one of its strongest halves to pull US$6.3bn of future cash forward.
On the face of it, BHP’s HY26 was one of the strongest results of Mike Henry’s tenure: underlying EBITDA of US$15.5bn, up 25%, at a 58% margin; attributable profit of US$6.2bn; and operating cash flow of US$9.4bn. 1 For the first time since BHP began reporting a copper segment, copper delivered more than half of group EBITDA, at a 66% margin, while Western Australian iron ore earned a 62% margin. 1 Net debt of US$14.7bn sat at about 0.5× annualised EBITDA on ZMK’s arithmetic, return on capital reached 23.6%, and the interim dividend was 73 US cents. 1
And yet, against that backdrop, BHP set out two agreements that together unlock US$6.3bn of cash, with a stated path to about US$10bn. 2 The headline act was a Wheaton streaming deal that sold BHP’s share of Antamina’s silver for US$4.3bn upfront, which BHP calls the most valuable streaming transaction to date. 3 Alongside it sat a US$2bn power agreement on the iron-ore business, 4 and in April the Carajás copper sale closed. 5 A month after the results, the Board named Brandon Craig, who has run much of the growth pipeline as President Americas, to succeed Henry from 1 July. 6 When a company this strong is pre-selling its cash flows, the interesting question is not the framing. It is what the numbers are telling you about the risk it now carries.
The silver stream pre-sells 80% of the upside to fund a capex peak.
The most revealing line in the HY26 deck is footnoted, not headlined: the upfront proceeds from the silver stream approach the consensus NAV of BHP’s entire 33.75% stake in Antamina. 2 Read that again. BHP received, in cash, roughly what the market values the whole interest at, by selling only the silver byproduct, and keeping the copper, zinc, lead and molybdenum. Either Wheaton overpaid and BHP captured a windfall, or the sell-side has been quietly under-marking BHP’s non-operated joint ventures for years. Probably both.
But a windfall at execution is not the same as a good trade over time. The stream runs for the life of the mine, and BHP now receives just 20% of the spot silver price on every ounce delivered. 3 In other words, it has pre-sold 80% of the upside on precisely the commodity Wheaton is betting will rise. And the accounting is its own tell: management states the US$4.3bn is “not expected to increase reported debt levels.” 3 In substance, this is leverage. In form, it is not.
You do not sell your best byproduct at the top of its cycle unless you need the cash somewhere else, and BHP’s capex tells you exactly where.
The growth bill is larger and longer than the headline. BHP’s capex guidance across FY26–30 adds up to roughly US$52bn, and more once non-operated joint ventures are counted. 1 The execution record has cracked. Jansen Stage 1 was sanctioned at US$5.7bn and now stands at US$8.4bn, a 47% overrun. 1 7 BHP itself calls Jansen an outlier: its other major projects since 2013 averaged about 3% over their sanction estimates, against about 37% for the mining industry. 2
That is why the disposals matter. Over the past decade BHP returned more than US$110bn to shareholders, around 70% of its market capitalisation, 2 and the market has priced that cadence in. On ZMK’s arithmetic through the capex peak, the distributable cash left after sustaining capital, growth, JV calls, tax and Samarco falls to roughly US$3–5bn a year, below both the decade’s pace and the implied minimum dividend. It holds at spot; it does not hold in the downside.
