• Completion of design, build and test phase of AU4, 40kg thrust Micro Gas Turbine
• Significant engineering milestones achieved within engine development technology pathways
• Strong active engagement with international defence Primes and UAV platform integrators

Aurora Labs Ltd has provided its quarterly report to shareholders, highlighting key achievements in its Micro Gas Turbine (MGT) program. The company completed the design, build and initial test phase of the AU4 micro gas turbine, engineered for UAV propulsion and delivering 40kg of thrust. Significant design improvements were made, including the removal of over 40 individual parts through component integration. Parallel improvements to the combustion assembly and thermal management resulted in a 6% reduction in fuel consumption compared to conventional systems. The AU4 and AU2 propulsion engine systems position Aurora Labs at the forefront of attritable engine manufacturing for Unmanned Aerial Vehicles (UAV), offering a scalable, sovereign-built solution. The company's presence at the 2025 Avalon Airshow marked a major milestone in advancing its business development objectives, engaging with UAV developers, defence Primes, and government delegations to explore the integration of its propulsion systems. This generated strong expressions of interest and initiated pathways towards formal test demonstrations and collaborative evaluations. Following Avalon, Aurora Labs representatives extended their engagement program with a visit to Washington D.C., participating in the Sea-Air-Space naval conference to further deepen international relationships and support the company's growing strategic footprint in key allied markets. Ongoing R&D efforts using the AL250 platform have directly contributed to material performance in the propulsion component tests, with additive manufacturing trials helping optimize engine weight, thermal characteristics, and operational endurance.

The company is progressing towards scaled production and certification compliance for its Micro Gas Turbine engine family, with key focus areas for the next quarter including procuring purchase orders for first sales, advancing infield testing and verification, formalizing defence and aerospace partnerships, and expanding design and testing activity on higher-thrust propulsion systems.

With the initial development phase of the Micro Gas Turbine program complete, Aurora Labs' focus has shifted to scaling production and securing commercial agreements. The company is well-positioned at the leading edge of sovereign propulsion systems development through additive manufacturing, and is actively pursuing opportunities to further expand its capabilities and strategic partnerships in the defence and aerospace sectors.
