Highlights

• Deep Yellow withdrew its target of a Tumas final Investment decision in the December 2026 quarter and has not set a new date.

• Detailed engineering was 85 per cent complete, and civil and concrete works have started on site, funded from existing cash.

• Debt work led by Nedbank is under way, but financial close remains subject to conditions and final documents.

• The company says funding is the central issue, with an updated Capital cost and value case still to come.

Why has Deep Yellow (ASX:DYL) paused the final investment decision on its flagship Tumas uranium project when uranium prices are high? The company's answer is funding, not geology or engineering. It said current Equity market conditions did not support the decision, and it did not set a new date.

The decision matters because Tumas, in Namibia, is the project meant to turn Deep Yellow from a developer into a producer. Building a mine needs a large funding package, normally a mix of debt and new equity. Deep Yellow has signalled it does not want to raise equity on current terms.

What Deep Yellow does

Deep Yellow is a uranium explorer and developer. Uranium is mined and sold as uranium oxide concentrate, measured in pounds of U3O8, and used as fuel for nuclear power stations. The company has no Mining Revenue yet. Its future income depends on getting mines built and on the price utilities pay for uranium.

Its portfolio has two main development projects. Tumas, in Namibia's Erongo region, is planned to produce 3.6 million pounds of U3O8 a year. Mulga Rock, in Western Australia, is planned at 3.5 million pounds a year. Its mining licence for Tumas runs to September 2043. The company also explores in Namibia and in the Alligator River region of the Northern Territory.

At 30 June 2026, Deep Yellow reported total mineral resources of 428.2 million pounds of U3O8. Ore reserves were 121.8 million pounds. Of those reserves, 79.5 million pounds sit at Tumas and 42.3 million pounds at Mulga Rock. The company's stated long-term goal is a group output of more than 10 million pounds a year.

Construction continues on a smaller scale

The FID delay does not mean work has stopped. Deep Yellow's September quarter report, released on 28 October 2026, said detailed engineering was 85 per cent complete. More than 85 per cent of major process plant equipment had been tendered. Long-lead packages had been executed or conditionally awarded, pending a notice to proceed.

On site, civil and concrete works have started. The company said in October that about 170 tonnes of reinforcing steel had been installed, and four contracts with Namibian firms worth N$42.1 million (about A$3.7 million) had been awarded. Namibia's Environmental Commissioner renewed the project's environmental clearance certificates. Deep Yellow says these works are fully funded from existing cash.

Debt work is also under way. Nedbank is the mandated lead arranger, and Credit approvals were in progress at the end of the quarter. Financial close is still subject to conditions and final documents. The Quarterly Report did not mention any uranium sales contracts.

Cash and financial results

Deep Yellow reported a net profit after tax of A$13.3 million for the year ended 30 June 2026, compared with A$7.2 million a year earlier. Because the company does not yet produce uranium, this profit does not come from mining. Reported revenue of A$7.4 million mainly reflects other income on its cash holdings, a point readers should keep in mind when looking at earnings-based measures.

Cash and deposits were about A$160 million at 30 June 2026, and the company was debt free. By 30 September 2026, cash had fallen to A$144.7 million.

That cash is enough for early works but not for a full mine build. The company has not published an updated capital cost for Tumas. Its 2026 Annual Report said the previous estimate was being revised. Deep Yellow has said an optimisation study and updated value case are nearly complete. It plans to release them in a comprehensive project update covering schedule, mining plan, costs and the financial model.

Uranium market conditions

The uranium market itself has been firm. Deep Yellow's quarterly report cited an average long-term contract price of US$96.50 a pound at 30 September 2026, up 16 per cent on a year earlier. The average Spot Price was US$89.63 a pound. Long-term prices matter most for a new mine.

Managing director Greg Field, who took over in February 2026, has said the company remains committed to Tumas and is pursuing the funding needed for full construction. The company's report argues that uranium equities do not yet reflect encouraging market fundamentals. That is the company's view, not an independent assessment.

Risks and what to watch

The main uncertainty is the timing and form of Tumas funding. A future FID will depend on debt approvals, the size of any equity raising, and the updated cost estimate.

Uranium prices can be volatile, and a new mine typically needs sales contracts to support lenders. Deep Yellow has not announced offtake agreements for Tumas. Namibian approvals are also relevant. The quarterly report noted that renewals are pending on some exploration tenements, while two Nova licences expire on 18 December 2026. Agreements with the state power and water utilities were still being negotiated or finalised.

A revised feasibility study is under way, and the company targets first product about two years after Tumas production starts, so delays at Tumas push that back as well.

Near-term markers include the comprehensive Tumas project update, progress on the Nedbank-led debt package, a pipe Supply contract expected by the end of 2026, and a water pipeline tender planned for early 2027.
