TITANIUM METAL OPERATIONS UPDATE

Commissioning and Ramp-Up of Commercial Operations

Commissioning of IperionX’s Titanium Manufacturing Campus in Virginia continued at pace during the quarter, with steady-state full-system titanium production targeted to commence by mid-2025.

Figure 1: Titanium Production Facility, location of the HAMR furnace operations

The HAMR furnace has consistently demonstrated the process’s effectiveness in producing high-quality titanium metal powder that exceeds industry standards. During successful commissioning, IperionX has identified significant process improvements that are expected to support both higher nameplate capacity and low-capex scalability of the HAMR process.

Based on current performance with new process improvements, IperionX anticipates revising its original nameplate capacity of 125 metric tonnes per year upwards, with new titanium powder production capacity expected to be confirmed by mid-2025. Notably, the majority of ancillary production process systems have already been scaled beyond the nameplate capacity, which supports future titanium production growth via modular addition of HAMR furnaces at lower capital.

In parallel, IperionX has completed commissioning of its initial powder metallurgy manufacturing capabilities at the Titanium Manufacturing Campus and Advanced Manufacturing Center, that uses the patented Hydrogen Sintering and Phase Transformation (HSPT) technology. This includes:

Commissioning of traditional vacuum furnace based HSPT sintering capacity, with future capacity enabled by minor modifications to existing HAMR units

Installation of a cold-isostatic press, enabling manufacture of longer, high-aspect-ratio parts such as titanium tubes, rods, and fasteners

Progression of binder jetting development, expanding the range of potential low-cost titanium product formats

IperionX now possesses an installed manufacturing base capable of transforming titanium powder into a wide range of low-cost, high-performance forged titanium products — delivering a full scrap-to-product solution through proprietary HAMR and HSPT technologies.

Accelerating Customer Engagement and Strategic Partnerships

IperionX made significant progress across multiple product development and qualification programs with leading customers in the defense, automotive, and consumer electronics sectors. During the quarter, interest expanded to include additional high-value and high-volume industries, particularly aerospace — underscoring growing demand for sustainable, low-cost titanium components.

IperionX has unlocked higher-volume prototyping capacity and is actively engaged with eight commercial partners on pilot-scale production and qualification programs. As IperionX advances toward steady-state production across both titanium powder and titanium powder-to-parts manufacturing, the capacity to engage new customers, deliver prototypes, and transition into contracted production is expected to accelerate significantly.

Initial product development is focused on titanium components that suffered from high scrap rates and low material yield under traditional manufacturing methods - products that are high-cost despite relatively simple geometries. These include titanium fasteners (nuts, bolts, washers, lug nuts), titanium housings for consumer electronics, and titanium enclosures for luxury goods. These titanium products offer high-volume opportunities across multiple markets and represent a logical entry point for commercial rollout.

As operations scale, IperionX expects to expand product development activities to support a growing customer pipeline across a wide range of industries, including those targeting advanced robotics, mobility, and precision engineering.

Commencement of 2026-2030 Expansion Studies

The up to $47.1 million U.S. Government IBAS award announced during the quarter provided the catalyst for IperionX to commence detailed expansion plans, targeting execution and production in 2026. The scale-up plan and the recent success in operation of the HAMR furnace also enables IperionX to develop scoping level plans for additional growth from 2027.

These plans will continue to be focused on the manufacturing of titanium metal products via the HAMR and HSPT process using 100% scrap as the raw material. IperionX anticipates finalizing these plans, presenting them to the U.S. Government for consideration, and subsequent public release in mid-2025.

U.S. GOVERNMENT ACTIVITIES

IperionX was awarded up to US$47.1 million in funding by the U.S. Department of Defense (DoD) to strengthen the U.S. Defense Industrial Base by accelerating development of a resilient, low-cost, and fully-integrated U.S. mineral-to-metal titanium supply chain. The DoD has obligated US$5 million to expedite the Titan Critical Minerals Project in Tennessee to ‘shovel-ready’ status. The remaining up to US$42.1 million is expected to be obligated by the DoD over the duration of the agreement, with the funds to be applied to facilitate vertical integration and increased titanium production capacity at IperionX’s Titanium Manufacturing Campus in Virginia.

Additionally, the Board of Directors of the Export-Import Bank of the United States (EXIM Bank) approved an equipment finance loan of US$11.0 million to support the significant expansion of IperionX’s advanced titanium manufacturing capabilities, subject to the completion and execution of definitive documentation. The EXIM Bank loan will finance the acquisition of state-of-the-art manufacturing equipment, including advanced additive manufacturing systems and precision machining tools.

IperionX is undertaking a process relating to private activity bonds, with the Industrial Development Authority of Halifax County, Virginia (IDA) authorizing the issue of tax-exempt bonds of at least $100 million and up to $400 million. IperionX is currently advancing a process relating to the potential issue of these tax-exempt private activity bonds, which, subject to further approvals, is expected to conclude in late 2025.

IperionX continues to advance multiple applications for additional U.S. Government funding, with potential for accelerated review under the new Administration. A select list of U.S. government funding opportunities is shown below:
