1.	2025 OPERATIONS: COMMERCIAL SCALABILITY VALIDATED BY HIGHER TITANIUM PRODUCTION CAPACITY AND LOWER UNIT COSTS

IperionX has fully commissioned all critical systems at its titanium production facility in Virginia, demonstrating steady-state production of high-quality, low-cost titanium metal products directly from recycled titanium scrap, using IperionX’s proprietary HAMR and HSPT technologies.

This milestone proves that our proprietary technologies can deliver a low-cost, fully integrated, circular titanium supply chain in the United States.

Structured process improvements and optimization has lifted nameplate titanium powder production capacity by 60% - from 125 tpa to 200 tpa - without additional capital spend. Higher throughput, lower reagent intensity and reduced production cycle times are expected to cut operating costs down to ~$55/kg. This step-change reduction is driven by:

◾

Economies of scale that reduce unit labor costs;

◾

Lower reagent intensity; and

◾

Superior energy efficiency, which delivers more than 50% energy savings compared to the traditional Kroll & ingot melting process.

Our process-innovation and improvement program is expected to further increase nameplate titanium production capacity in 2026.

Titanium manufacturing sales are expected to progressively scale through 2026, with a positive EBITDA inflection point projected by year-end 2026.

IperionX now has capacity to manufacture a wide range of high-value titanium products for its customers, including:

◾

Defense: Multiple active U.S. Department of Defense projects focused on lightweight, corrosion-resistant components

◾

Consumer electronics: First production runs on post-consumer titanium scrap underway to fulfill the announced collaboration with ELG Utica on July 3, 2024

2.	U.S. DOD BACKED EXPANSION BY MID-2027 HAS COMMENCED, TO BECOME THE LARGEST & LOWEST COST U.S. PRODUCER

IperionX is scaling titanium capacity to 1,400 tpa at its Virginia Titanium Manufacturing Campus, with commissioning slated for mid-2027, positioning IperionX to be America’s largest and lowest-cost titanium powder producer.

The total expansion capital is ~US$75 million, including ~US$17 million in contingency, and is majority funded through the U.S. Department of Defense (DoD) Industrial Base Analysis and Sustainment (IBAS) award of US$47.1 million, along with IperionX's balance sheet cash. Additional contract awards under the US$99m SBIR Phase III program and access to Private Activity Bonds enhance financial flexibility.

The 1,400 tpa expansion accelerates a more resilient and sustainable U.S. titanium supply chain, cutting reliance on foreign imports and supporting national security for aerospace, defense, and electric vehicles. This integrated expansion program will deliver end-to-end titanium scrap-to-part capacity with downstream manufacturing equipment - powder-metallurgy presses (Appendix A), forging, and additive manufacturing - to process 100% recycled scrap or domestic feedstocks into high-quality titanium powders and high-performance titanium components.

Targeted titanium products

The seven-fold increase in titanium production capacity will target high-value, high ‘buy-to-fly’ ratio titanium components, in the form of near-net-shape and manufactured products, with a target market pricing range of $180/kg to $400/kg.

By leveraging cost advantages from proprietary HAMR and HSPT technologies, IperionX expects a material cost reduction across a range of titanium product categories, including:

◾

Titanium fasteners

Fasteners — bolts, screws, nuts, washers, rivets — are ubiquitous across major U.S. markets in automotive, construction, aerospace, marine, and industrial machinery. Titanium fasteners represent a large addressable market for IperionX. Leveraging our integrated patented technologies and near-net-shape manufacturing, IperionX modeling indicates scope for product cost reductions of over 80%, and in some cases more than 90%, versus current market levels.

Figure 4: Productivity benefits of manufacturing titanium fasteners with IperionX’s patented technologies

The global titanium fastener market is ~US$4.3 billion¹ annually, with the global stainless steel fastener market ~US$15.2 billion² annually. Lower-cost titanium fasteners, priced competitively with stainless steel, could unlock accelerated substitution, volume growth and a larger addressable market.

Enclosures & controls (consumer electronics)

The premium consumer electronics market is adopting titanium at scale, with leading global brands adding titanium to flagship devices. Over 1.2 billion³ mobile phones and 180 million³ smartwatches are sold every year.

IperionX offers a fully circular titanium supply chain that can convert consumer-electronics titanium scrap into high-quality titanium powder and titanium near-net-shape components, at lower energy, cost and environmental footprint. Our first commercial project is already in progress to deliver into this market.

Gears & actuators (humanoid robotics)

The humanoid robotics market is forecast to expand from under US$3 billion today to more than US$38 billion⁴ by 2035. Core to these systems are lightweight, strong, corrosion-resistant gears and actuators — ideal for titanium and perfectly suited to our uniaxial press-and-sinter manufacturing route, which mirrors traditional steel powder metallurgy gear production.

Titanium brackets

Titanium brackets are the natural complement to titanium fasteners across aerospace, marine, and construction—combining high strength, low weight, and exceptional corrosion resistance.

Mill products

Although not central to our market product plan, IperionX’s powder metallurgy process can produce near-final-gauge titanium plate, sheet, and bar after sintering - bypassing large portions of the titanium melt–forge–roll chain. Multiple industry partners are collaborating to quantify the cost and efficiency gains.

High-value additive manufactured (AM) parts

For strategic programs and customers, we will manufacture high-value complex titanium parts via LPBF and EB-PBF, smaller in output but with high-value margins. As the expected lowest cost U.S. titanium-powder producer, IperionX will strengthen the additive manufacturing supply chain and deliver lower-cost AM titanium parts.

Capital and operating cost estimates

Operating cost estimate

Operating costs for titanium powder are projected at US$29 per kg, at full utilization of 1,400 tpa capacity. Direct conversion of titanium scrap to powder using proprietary technologies, followed by near-net-shape consolidation and forging, sharply reduces waste and supports value-in-use pricing that approaches competitiveness with stainless steel and aluminum while maintaining titanium’s strength-to-weight, corrosion, and biocompatibility advantages.

Titanium powder-to-part consolidation and forging costs (incremental, ex-powder) are projected to range by manufacturing modality for standard products such as fasteners: uniaxial pressing US$7–30/kg; cold isostatic pressing US$4–15/kg; binder jet printing US$50–150/kg; LPBF / EB-PBF US$100-375/kg (per kg of near-net-shape part).

Capital cost estimate

The expansion to 1,400 tpa is expected to cost US$75.1 million, delivering best-in-class capital intensity for production of finished titanium parts, representing an order of magnitude improvement compared to the current Kroll-based supply chain, which is characterized by high energy consumption, complex multi-stage processing, the generation of up to 90% waste, and as such, exceptionally high capital intensity. IperionX's modular, scalable approach leverages off-the-shelf furnace technology and patented processes to achieve superior efficiencies, shorter cycle times, and higher yields, while eliminating toxic chemicals and reducing environmental impacts.
