Iluka Resources

The Business

Iluka mines zircon and titanium minerals, holding roughly a fifth of the global zircon market and commanding a premium price for it. It is also building Eneabba, the only integrated refinery outside China capable of separating both light and heavy rare earth elements, funded by a $1.65 billion non-recourse government loan that keeps the project's risk off Iluka's core balance sheet. It also holds a 20% stake in Deterra Royalties, worth around $430 million. Three distinct businesses, one share price.

Recent Performance

Earnings have been savaged by a two-year mineral sands downturn: revenue fell from $1,129 million in FY24 to $976 million in FY25, and EBITDA margin compressed to 13% in the first half of FY26 as Iluka idled the Cataby mine and Synthetic Rutile kiln to preserve cash. The company has been drawing down a $951 million inventory stockpile built during the downturn, generating cash even as reported earnings stayed weak.

Outlook

Mineral sands EBITDA margin is expected to climb materially over the next three years as Balranald ramps up and Cataby potentially restarts, spreading fixed costs over higher volumes. Revenue should recover steadily through the forecast period, with the largest single-year jump concentrated in the final year as volumes normalise. None of this recovery depends on rare earths, which we treat as a separate, binary outcome layered on top of the core business.

Key Risks

Eneabba is a first-of-kind facility with no operating precedent anywhere outside China; a significant delay or technical failure would materially impair the value of the project and could weigh on sentiment across the group even though the debt funding it is non-recourse. A reversal of China's rare earth export controls would undermine the structural pricing premium that the refinery's economics depend on. Sustained Australian dollar strength above recent levels, or zircon prices staying soft, would blunt the pace of the mineral sands recovery without derailing it outright.

What to Watch

The thesis-defining event is Eneabba's hot commissioning in the first half of 2028, which will confirm whether the technology works at commercial scale.

• H1 2028 Eneabba hot commissioning — binary resolution of the project's technical viability.
• H1 2027 80% construction milestone — on-schedule confirmation would lift confidence ahead of commissioning.

Company Description

Iluka's core business is mining and processing mineral sands, principally zircon (used in ceramics and specialty glass) and titanium feedstocks, from operations in Western Australia and New South Wales. This segment generated $976 million in revenue in FY25 and remains the company's primary cash generator. Alongside it, Iluka is constructing Eneabba, a rare earths refinery in Western Australia currently at 60% construction completion and contributing zero revenue today. A 20% equity stake in royalty company Deterra, spun out of Iluka in 2020, rounds out the group and is valued at market at roughly $430 million.

Where the Growth Is

Eneabba is the single variable that matters most for Iluka's future value. It currently contributes nothing to earnings but targets $250-400 million of EBITDA at full capacity of 4,000-5,000 tonnes of rare earth oxides annually. The first offtake contract is signed, guaranteeing a minimum US$155 million over four years. The swing in outcomes between commissioning success and failure is large enough on its own to matter more than the entire mineral sands business.

Competitive Position

In mineral sands, Iluka holds roughly a fifth of the global zircon market and consistently earns a price premium of over US$100 a tonne through quality and blending capability, a position that has held steady through the downturn. That business has a moat that is real but not permanent, likely to hold for five to seven years before reserve depletion and competitor supply erode it without further investment. Eneabba is different: no other integrated light and heavy rare earths separation facility exists outside China, and government backing via the non-recourse loan structure entrenches that position for a decade or more, assuming the technology works.

Management & Capital Discipline

Management funded Eneabba through non-recourse project debt rather than issuing equity, protecting existing shareholders from dilution while the project is built. The decision to idle Cataby and the Synthetic Rutile kiln during the downturn preserved cash rather than chasing volume into a weak market. On Balranald, a newer underground mine, management has used deliberately hedged language about ramp-up performance rather than promising a smooth path, a signal of appropriate caution rather than overselling progress.

Financial Position

Iluka's mineral sands balance sheet carries net debt of roughly 2.4 times EBITDA currently, elevated by the earnings trough but falling rapidly as margins recover and inventory converts to cash. Around $429 million remains undrawn on the group's revolving facility. The Eneabba project debt is ring-fenced and non-recourse to the rest of the group, meaning a project failure would not threaten the mineral sands balance sheet. Overall financial health is adequate to weather a further downturn, though not comfortable.
