Iondrive’s new study shows a 379% IRR. One feedstock assumption explains much of it

Iondrive Limited (ASX: ION) has reported sharply stronger modelled economics for its proposed U.S. rare earth recycling business, assigning a post-tax net present value of US$243 million to a single IONSolv processing module designed to recover neodymium, praseodymium and dysprosium from end-of-life permanent magnets. The updated evaluation models annual revenue of US$121.8 million, EBITDA of US$62.1 million and development capital of just US$11.9 million for a 2,402-tonne-per-year module planned for Oklahoma.

The headline returns are unusually high. Iondrive’s model produces a post-tax internal rate of return of 379%, a post-tax payback period of approximately 0.24 years from first production and a 10-year operating life after one year of construction. On a simple basis, the US$243 million NPV is more than 20 times the modelled US$11.9 million development capital, while the projected EBITDA margin is approximately 51%.

Those economics are not yet equivalent to a bankable project or final investment decision. The model assumes that Iondrive can secure approximately 2,402 tonnes per year of end-of-life magnet feedstock averaging 30.66% rare earth oxides, substantially richer than the material underpinning its earlier November 2025 evaluation. Feedstock availability, product qualification, engineering, permitting, financing and offtake therefore remain central commercial risks before the Oklahoma module can be treated as an operating project.

Investors nevertheless reacted strongly. Iondrive shares closed September 7 at A$0.11, up 29.4% from A$0.085, after trading as high as A$0.12 on approximately 41.4 million shares. The move followed a 16.4% gain on September 4, meaning the stock has experienced a rapid re-rating even before Iondrive has committed to construction of the first commercial module.

Why did Iondrive’s projected economics improve so dramatically from the previous study?

The biggest change is not a sudden reduction in processing costs or construction capital. It is the assumed feedstock.

Iondrive’s November 2025 evaluation effectively modelled feedstock at roughly 7.2% rare earth oxide content. The September 2026 update assumes 30.66%, more than four times the earlier grade, while annual module throughput rises from approximately 2,000 tonnes to 2,402 tonnes. The higher metal content drives projected payable rare earth oxide production from roughly 115 tonnes annually in the earlier work to approximately 624 tonnes in the updated model.

That shift fundamentally changes revenue potential without requiring a proportional increase in the physical size of the plant. Processing a tonne of feed containing four times as much valuable rare earth material can produce substantially more saleable output while many fixed elements of plant capital remain relatively stable.

The updated study therefore demonstrates the leverage inherent in Iondrive’s business model, but it also concentrates the risk around feedstock quality. The economic case works particularly well if the company can consistently secure magnet-rich waste streams with composition close to the 30.66% model assumption. If commercially available feedstock averages materially lower grades, revenue and project returns would need to be recalculated.

Iondrive has already completed recovery testing on commercial U.S. magnet feedstock supplied by Colt Recycling. Independent work reported recoveries of approximately 96.5% for neodymium, 96.5% for praseodymium and 93.5% for dysprosium, alongside approximately 99.9% iron rejection. Those recovery numbers support the process chemistry, but they do not yet prove that enough similarly rich material can be contracted every year for a full-scale commercial module.

Why does dysprosium matter so much to the US$121.8 million revenue forecast?

Dysprosium is the most revealing part of the economic model because its financial contribution is much larger than its physical share of production.

The updated evaluation assumes dysprosium oxide accounts for only about 4.45% of contained rare earth oxides, yet analysis of the model indicates it contributes roughly 49.5% of base-case revenue. The economics use a Western dysprosium oxide price around US$2,300 per kilogram, making the heavy rare earth disproportionately important to the revenue case.

That concentration creates both opportunity and sensitivity. Dysprosium is valuable because it is used to improve the high-temperature performance of permanent magnets deployed in applications including electric vehicles, wind turbines, aerospace and defence systems. Western governments are also attempting to develop supply chains outside China for strategic rare earth materials.

For Iondrive, recovering dysprosium from discarded magnets can therefore capture far more value than a process focused only on the more abundant neodymium and praseodymium components.

It also means the NPV should not be viewed as insensitive to product mix or rare earth prices. If dysprosium content in available feedstock proves lower than the model assumption, or Western dysprosium prices weaken materially, the effect on revenue could be disproportionate to the reduction in total oxide tonnage.

Can Oklahoma incentives really cover almost half of the first module’s development capital?

The Oklahoma Department of Commerce has provided Iondrive with a letter of support identifying potential state and local incentives worth up to approximately US$5.2 million for a first commercial module. The broader support framework could exceed US$15 million if Iondrive ultimately develops three modules.

Compared with the US$11.9 million development-capital estimate in the latest study, US$5.2 million is equivalent to approximately 44% of the modelled first-module requirement. That helps explain why management is prioritising government incentives, strategic capital and project-level financing before considering additional shareholder equity.

The potential incentive package should not be treated as money already received or as a guaranteed 44% government contribution. A letter of support can identify programmes and potential assistance, but final amounts generally depend on project location, investment, job creation, eligibility conditions and formal applications.

Iondrive is also pursuing relevant U.S. federal support. Its June-quarter report highlighted a U.S. Department of Energy programme providing US$134 million for projects demonstrating commercial recovery and refining of rare earths from unconventional feedstocks, including electronic waste. The company has not announced that it has been awarded a specific amount from that federal programme.

The funding strategy is therefore potentially attractive because the modelled capital requirement is small relative to the projected economics, but the financing package still needs to be assembled before construction can proceed.

Does Iondrive have enough cash to finance the Oklahoma project itself?

Iondrive ended June 2026 with approximately A$7.0 million of cash and expected another A$1.4 million of near-term inflows from its research and development tax incentive and remaining Australian Industry Growth Program grant. The company reported approximately five quarters of funding based on its June-quarter operating cash outflow.

That cash position provides development runway but should not be confused with funding for the proposed U.S. commercial plant.

Iondrive is already spending heavily on technology development. FY26 research and development expenditure reached A$6.37 million, including A$4.18 million associated with pilot-plant construction. The company reported a A$7.02 million net loss for FY26 despite revenue increasing to A$3.64 million, with much of that revenue itself coming from grants and the R&D tax incentive rather than commercial rare earth sales.

Grant funding has helped reduce the burden on shareholders. The Australian Government’s Industry Growth Program is funding 50% of eligible pilot-plant expenditure up to A$3.89 million, while Iondrive has stated that its preferred Oklahoma funding sequence prioritises incentives, federal programmes, strategic partners and project capital before shareholder equity.

That approach is particularly important because Iondrive’s commercial thesis is now much larger than its historical financial base. A company reporting A$3.64 million of FY26 accounting revenue is evaluating a single module that theoretically could produce more than US$120 million of annual sales. Bridging that gap requires far more than financing a factory; it requires feedstock contracts, qualified products, customers and operational systems capable of supporting industrial-scale throughput.

Why should investors be cautious with the 379% IRR and three-month payback figure?

The numbers are mathematically valid within the assumptions used in the evaluation, but some of those assumptions are highly favourable compared with a conventional mining or industrial development project.

The model assumes no production ramp-up and full utilisation from the start of commercial operations. That means the plant begins generating modelled revenue at full operating performance instead of spending several quarters progressively increasing throughput, recoveries and product quality.

A commercial commissioning period could produce different economics. New processing facilities can experience lower initial utilisation, product-specification issues, maintenance requirements and working-capital pressures while operations stabilise.

Iondrive’s modular approach may reduce some of those risks because the proposed facility is much smaller than a conventional mine and concentrator. The company is also completing a five-tonne production campaign intended to provide larger product samples for qualification and advance the technology beyond laboratory-scale testing.

The updated evaluation is therefore valuable as an indication of what a successful commercial module could look like, but investors still need evidence that the assumed operating performance can be replicated continuously at industrial scale.

Why did Iondrive shares jump 29% when the company still has no commercial rare earth revenue?

The September 7 rally reflects the difference between technology validation and modelled commercial economics.

Before the latest evaluation, investors already knew that IONSolv could recover neodymium, praseodymium and dysprosium from commercial U.S. magnet waste. What changed was management’s estimate of the economics that could emerge if those recoveries are paired with higher-grade feedstock in a commercial module.

Iondrive closed at A$0.11 after reaching A$0.12, compared with A$0.085 on September 4 and A$0.058 as recently as August 26. The September 7 session alone added roughly 29% to the share price, while volume exceeded 41 million shares.

That re-rating increases the execution standard. Investors are now assigning considerably more value to the possibility that IONSolv becomes a commercial U.S. rare earth recycling platform rather than remaining primarily a research and pilot programme.

The next milestones therefore need to address the assumptions carrying the US$243 million NPV. Commercial feedstock contracts, product qualification, offtake agreements, completed front-end engineering, a selected Oklahoma site, confirmed incentives and an executable financing package would each remove a different layer of uncertainty.

The new study demonstrates that the potential economics are large if Iondrive can secure the right material and operate the plant as modelled. The more important question is whether enough 30.66%-grade feedstock exists on commercially sustainable terms to keep the first module running at the utilisation assumed in those exceptional return figures.
