Q4 FY26 report also covers SiNTL’s entry into drone, aerospace and satellite markets, and $8.45 million secured in funding

We’ve released our Appendix 4C activities and cash flow report for the quarter ended 30 June 2026 (Q4 FY26), and it was one of the busiest quarters in our history. We strengthened our balance sheet, signed a potential anchor customer for Aurora, and moved SiNTL out of the laboratory and into the hands of three independent parties for testing.

A new commercial pathway for Aurora

Following the end of the quarter, we announced a heads of agreement with an Australian data centre operator to develop up to 1 gigawatt (GW) of AI data centre infrastructure within the Aurora Energy Precinct. The staged development begins with a 17 MW campus supplied via our existing 33kV network connection, with PV and BESS on the west side, expanding to an approximately 200 MW anchor campus once our proposed 275kV transmission connection is complete on the east side, with a longer-term pathway toward gigawatt-scale deployment. The agreement grants the operator exclusivity over an initial 40-hectare development parcel while we negotiate definitive commercial agreements.

Separately, our approved 140 MW / 280 MWh Stage 1 BESS completed the technical requirements to progress to commercial transmission access negotiations with ElectraNet, following acceptance of generator performance standards by AEMO and ElectraNet.

SiNTL enters drone, aerospace and satellite markets

We established an aerospace and defence division, advised by a board of industry experts, to develop commercial opportunities for SiNTL across drone, UAV and aerospace applications spanning commercial, government and military markets.

We signed a battery evaluation agreement with Ukrainian government-approved defence manufacturer Energia 2000, which produces approximately 72,000 military drones annually, to test SiNTL across multiple UAV platforms through six staged milestones. We also entered a testing and commercialisation agreement with Italian space technology company Orbit Boy to evaluate SiNTL for satellites, launch systems and defence applications. After quarter end, Orbit Boy advised that SiNTL had been selected as the primary energy storage candidate for its planned defence launch vehicles and ARCap satellite servicing module, a selection that requires successful completion of the testing program.

After quarter end, our SiNTL cells exceeded 550 mAh/g across all tested configurations, with optimised formulations recording above 600 mAh/g on initial cycles, around 60% higher power capacity than traditional graphite anode batteries.

Funded to progress multiple workstreams at once

We secured firm commitments for $8.45 million before costs via a placement at $0.10 per share, cornerstoned by Tribeca Investment Partners. After quarter end, we received a further $2 million from the exercise of 14DOA options, and have 276 million in-the-money 14DOA options on issue that, if fully exercised, would deliver an additional $13.8 million in funding.

Peter Yaron, Chief Technology and Operations Officer, commented:

“Moving SiNTL from lab results into independent testing with Energia 2000 and Orbit Boy is a genuine step change for the technology. Combined with the funding to run those programs alongside our scale-up work at George Washington University, we’re now positioned to generate real third-party validation data across drone, satellite and defence applications at the same time, rather than sequentially.”

What’s next

Near-term priorities include commissioning SiNTL scale-up equipment at George Washington University, progressing the Energia 2000 and Orbit Boy testing programs, advancing commercial negotiations under the Aurora data centre heads of agreement, and continuing the Stage 1 BESS transmission connection negotiations with ElectraNet.

We’re pleased to announce we’ve signed a Heads of Agreement with an Australian data centre operator to develop up to 1 GW of AI data centre infrastructure at our Aurora Energy Precinct in South Australia, anchored on Aurora’s firmed renewable generation and storage assets.

The operator has been granted exclusivity over an initial 40-hectare parcel within Aurora’s 15.8 km² landholding, which offers long-term tenure, up to 900 MW of solar generation potential, an approved 140 MW / 280 MWh battery energy storage system, high-voltage connection infrastructure, and access to fibre and water.

We’re proposing the development in three stages: an indicative 17 MW starter campus using the 33kV connection we announced last week, a 200 MW anchor campus once the 275kV transmission line is connected, and a longer-term pathway to gigawatt scale as Aurora’s renewable generation is progressively built out. The modular data centre technology involved is designed to work with renewable generation and storage, and can be relocated or replaced as technology evolves.

Under the proposed structure, we would provide the development parcel, power and connectivity, while our partner would bring the capital, technical expertise and operating capability to deploy and run the infrastructure. We intend to negotiate definitive agreements covering land access, behind-the-meter renewable energy, battery storage, grid connection and precinct services, and we’ll continue working with SA Power Networks, ElectraNet and other stakeholders to progress connection arrangements.

This partnership adds to the momentum building around Aurora and the wider Australian market: major AI infrastructure companies, including Anthropic, have publicly flagged requirements for 500 MW-plus sites in Australia, and other global technology companies have recently signed renewable power agreements to support their own data centre operations here — trends that speak well to Aurora’s commercial position.

Dr Kevin Moriarty, Executive Chairman, commented:

“This agreement validates Aurora’s strategy of attracting energy-intensive industries to a site purpose-built for renewable generation, storage and grid connectivity. The 33kV connection lets us start generating value from part of the precinct now, while the 275kV build-out and Aurora’s solar and battery storage development continue in parallel.”

We’ll keep the market updated as definitive agreements are executed or other material developments arise.

SiNTL™ Clears 550 mAh/g Milestone – Optimised Formulations Reaching 600 mAh/g

We have reached a significant milestone in our SiNTL™ silicon nanoparticle battery program, with SiNTL cells now exceeding 550 mAh/g across all tested configurations. Optimised formulations are recording above 600 mAh/g on initial cycles – more than 50% higher than conventional graphite anodes and approximately 20% above current commercial silicon-enhanced anode benchmarks.

What the results show

Testing of our latest SiNTL cell configurations produced strong results across three variants. Two variants exceeded 600 mAh/g on initial cycles, stabilising above 550 mAh/g at higher charge/discharge rates. A third variant, formulated with lower silicon content, achieved just under 600 mAh/g on initial cycles, stabilising at just over 500 mAh/g at higher rates.

The reduction in capacity at higher rates reflects the inherently lower electrical conductivity of silicon — a well-understood characteristic that does not affect peak capacity performance. Cycle life testing is underway, and results will be reported as they become available.

We regard these results as confirmation that SiNTL’s core material performance is on a credible commercialisation trajectory.

The path to consistent 600 mAh/g

Our development team at George Washington University, led by Professor Michael Wagner, is now evaluating carbon-enhanced SiNTL formulations to sustain 600+ mAh/g across a wider range of charge/discharge rates. Carbon coating is a proven technique for improving silicon conductivity in lithium-ion battery anodes, and we expect results in the near term.

Why energy density matters

Standard graphite anodes used by manufacturers including Samsung, Panasonic, CATL and LG are generally limited to around 372 mAh/g. SiNTL is designed as a drop-in upgrade – compatible with existing lithium-ion manufacturing processes without retooling or process redesign.

Higher-capacity SiNTL battery technology targets demanding applications where energy density is a critical design constraint: drones and UAVs, electric vehicles, spacecraft and satellites, military systems, robotics and industrial power tools.

Chief Technology and Operations Officer Peter Yaron said: “SiNTL cells are now surpassing 550 mAh/g across our test configurations, with our best-performing cells recording above 600 mAh/g at slow rates. That gives us real confidence in the material. The carbon enhancement work is the path to making 600 mAh/g the consistent operating baseline.”

SiNTL is developed under an exclusive global licence with George Washington University and is produced via a low-temperature, single-step synthesis process with approximately 97% demonstrated yield.

Orbit Boy to Begin Defence Rocket Manufacturing, Selects SiNTL™ as Primary Energy Storage Candidate

Our space technology partner Orbit Boy has announced plans to begin manufacturing defence launch vehicles, alongside a planned U.S. capital markets listing, and has selected our SiNTL™ silicon-anode battery technology as the primary energy storage candidate for these vehicles and its ARCap module.

This builds on the testing and commercialisation agreement announced 17 June 2026, extending SiNTL’s potential commercial scope beyond satellite power systems and the Solaris Space Defence Laser. We hold an equity position in Orbit Express Pty Ltd, and Orbit Boy’s planned U.S. listing may create a future value-realisation pathway for that holding.

The existing six-stage milestone testing programme remains unchanged, with results from each stage required to pass before the next begins.

Executive Chairman Dr Kevin Moriarty said the selection “is a strong validation of the technology’s performance characteristics” and materially extends the partnership’s commercial scope.
