NH3 Clean Energy Limited (ASX: NH3) ("NH3" or "the Company") is pleased to announce its participation in the pilot phase of the Ammonia Energy Association's ("AEA") Ammonia Certification System ("ACS") — a globally recognised certification framework designed to support the transparent, traceable and trusted international trade of low-emissions ammonia.

Participation in the ACS pilot further reinforces NH3's position as a leader in the development of its advanced, export-focused clean ammonia project and highlights the Company's commitment to delivering independently verified low-carbon ammonia to global markets.

Highlights

• NH3 has agreed to participate in the pilot phase of the AEA Ammonia Certification System, enabling the Company to pre-certify the expected emissions profile of ammonia to be produced from its planned WAH2 Project ahead of commercial operations
• Independent pre-certification provides prospective customers, financiers and strategic partners with increased confidence in the integrity and transparency of the WAH2 Project's decarbonisation credentials, supporting advanced discussions around future clean ammonia offtake arrangements
• Participation in the ACS positions NH3 at the forefront of emerging global clean ammonia standards and enhances the Company's ability to meet the growing requirements of international energy, shipping and industrial customers seeking verified low-emissions supply
• During operations, the ACS framework would enable ongoing certification of both the carbon intensity and origin of ammonia produced from the WAH2 Project, strengthening NH3's competitive position in premium clean fuel markets
• The associated AEA Ammonia Registry provides a secure digital platform supporting transparency, traceability and trusted data exchange across the ammonia value chain — key requirements for the development of global clean ammonia trade

NH3 Chairman, Charles Whitfield, commented: "Participation in the AEA Ammonia Certification System further demonstrates NH3's leadership in the emerging global clean ammonia sector. As international customers increasingly prioritise independently verified low-emissions supply, this initiative enhances the strategic positioning of our WAH2 Project and supports ongoing engagement with offtake partners. By participating in the pilot phase of this globally important certification framework, NH3 continues to lead the market in transparency, credibility and readiness for international clean ammonia trade."

AEA Executive Director, Trevor Brown, commented: "We're delighted that NH3 Clean Energy is participating in the AEA Ammonia Certification System pilot, joining ammonia producers, traders, and consumers from around the world. This highlights their proactive approach to transparency and rigorous carbon accounting in the clean ammonia market. Early engagement with internationally aligned certification systems like ours will play an important role in building market confidence and accelerating global trade in low-emission ammonia."

About the AEA Ammonia Certification System

The AEA Ammonia Certification System is a global certification system designed to facilitate the transparent, trusted international trade of low-emission ammonia. It is a voluntary system that allows producers, traders, and consumers to demonstrate key environmental attributes — namely carbon footprint and origin — using independently verified data.

The system entered its pilot phase in October 2025 together with the launch of a global registry to manage the generation, transfer, and retirement of certificates. The AEA Ammonia Registry, built and operated by MiQ, provides participants with a digital infrastructure that enables secure data transfer, transparency, and traceability across the ammonia supply chain at scale.

About the WAH2 Project

The WAH2 Project is NH3's flagship project to supply low-emissions ammonia to the decarbonising powerhouse economies of the Asia Pacific, including Japan and South Korea, as well as being a source of decarbonised "bunker" fuel for powering bulk carriers carrying iron ore from Australia to Asia. The project is well placed as Asia's energy transition drives an increasing demand for low-emissions energy.
