Key Highlights

• Its costs are small, and underlying EBITDA in FY26 was A$222.2 million on a 94 per cent margin.

• Deterra receives 1.232 per cent of MAC's Australian dollar free-on-board revenue.

• The company says the area represents about 9 per cent of global seaborne iron ore Supply and could operate for more than 45 years.

• Beyond MAC, the portfolio held 14 royalties across seven countries and five commodities at the FY26 result.

What is Deterra Royalties (ASX:DRR) doing with a Business built around one iron ore royalty, and why does it matter now? The company is using the cash from that Royalty to add copper and lithium exposure while it searches for a permanent chief executive. Its September 2026 quarter update showed the iron ore stream softening, so the pace and quality of that Diversification is the central question for the stock.

What Deterra actually owns

Deterra Royalties does not mine anything. It owns royalties, which are contractual rights to a share of the Revenue earned by miners operating other people's projects. Its costs are small, and underlying EBITDA in FY26 was A$222.2 million on a 94 per cent margin.

The flagship is the Mining Area C (MAC) royalty over BHP's iron ore operations in Western Australia's Pilbara. Deterra receives 1.232 per cent of MAC's Australian dollar free-on-board revenue. The company says the area represents about 9 per cent of global seaborne iron ore supply and could operate for more than 45 years.

Beyond MAC, the portfolio held 14 royalties across seven countries and five commodities at the FY26 result. Most are small or still in development, so iron ore dominates Earnings for now.

The FY26 result in numbers

For the year to 30 June 2026, revenue from continuing operations rose 6 per cent to A$236.2 million. MAC royalty revenue was A$234.4 million, compared with A$219.3 million a year earlier. BHP produced 152 million wet tonnes at MAC on a 100 per cent basis, which Deterra says is the first time output has exceeded the 145 million tonne nameplate in a single year.

Statutory net profit after tax rose 5 per cent to A$164.2 million, and underlying net profit rose 14 per cent to A$151.7 million. Statutory results include an A$8.4 million gain on asset sales, and the lower comparison year included larger gold offtake and capacity payment income, so the headline and underlying figures tell slightly different stories.

The board declared a final Dividend of 10.8 cents per share, fully franked, taking the full-year dividend to 23.2 cents versus 22.0 cents for FY25. The payout policy remains 75 per cent of net profit after tax.

Balance sheet and portfolio reshaping

Net Debt fell to A$132.5 million from A$270.6 million a year earlier, with A$357 million of a A$500 million Facility undrawn. Deterra sold non-core precious metals Assets in September 2025 for US$82 million, roughly A$124 million, and describes a pre-tax internal rate of return of about 28 per cent on that investment.

That sale Funded Debt reduction and left room for new deals.

The September quarter: a softer iron ore print

The portfolio update for the quarter ended 30 September 2026, released on 29 October, reported unaudited royalty revenue of A$46.4 million. That was down 25 per cent on the June quarter and down 15 per cent on the same quarter a year earlier.

The MAC royalty contributed A$45.8 million. Production of 34.3 million wet tonnes and sales of 32.2 million dry tonnes were each about 1 per cent lower year on year, so volumes explain little of the fall. The larger driver was price. Deterra cites an implied average revenue of A$115.2 per dry tonne, or US$81.3, which is 15 per cent lower in Australian dollar terms, along with elevated freight costs.

This shows the key sensitivity. Deterra carries no mining cost risk, but its revenue still follows the iron ore price and the Australian dollar.

New copper exposure at Santa Cruz

The most notable development in the update is the Acquisition of a net smelter return royalty over Ivanhoe Electric's Santa Cruz copper project in Arizona for US$74.15 million. The royalty rate is 1.68 per cent until the sixth anniversary of commercial production and 1.57 per cent afterwards.

Using a copper price of US$5.00 per pound, Deterra estimates about US$10.7 million a year of royalty revenue over the first 15 years, a 14.4 per cent annual Yield on the purchase price. That is a company assumption, not a forecast, and it rests on the project being financed and permitted. First copper cathode is expected in 2029, subject to those conditions. Initial Capital cost is US$1.4 billion, and a US Export-Import Bank preliminary letter covers up to US$1.1 billion of potential debt.

Royalties paid on projects that have not yet been built carry delay and funding risk. The payoff, if the project proceeds, is a second Commodity stream with a long mine life.

Lithium at Thacker Pass

Deterra also holds a 4.8 per cent gross revenue royalty on the Thacker Pass lithium project in Nevada. The rate would fall to 1.05 per cent if a partial buy-back worth US$13.2 million to Deterra occurs around first production.

The latest update says US$1.45 billion of the US$2.23 billion US Department of Energy Loan has been received. Estimated Capital Expenditure is US$2.93 billion, with 55 per cent incurred at 30 June 2026. Mechanical completion is targeted for late 2027, with commercial production in 2028. Lithium prices, construction costs and the pace of ramp-up will all affect when and how much this royalty contributes.

Leadership and risks to watch

Non-executive director Jason Neal remains Interim Managing Director and CEO while the board searches for a permanent appointment. Alex Morrison has resigned from the board for personal reasons, and the board is recruiting an additional independent non-executive director. A new chief executive could change deal selection and capital allocation priorities.

The main risks are:

• Iron ore price and Exchange Rate swings, which drive most current revenue.

• Operator decisions at BHP, including mine plans and production disruption.

• Development delays or financing gaps at Santa Cruz, Thacker Pass and other projects.

• Dependence on debt and Equity markets to fund new acquisitions.

• Leadership transition risk.

What comes next

Developments to watch include the December quarter update, any permanent CEO appointment, Santa Cruz financing and permitting, and Thacker Pass construction milestones through 2027.

Deterra's case rests on turning a high-margin iron ore stream into a broader royalty portfolio. Whether that works depends on commodity prices, operators and capital discipline, none of which the company controls.
