Selection of Sungrow Hydrogen as Electrolyser Supplier for Villeta

ATOME (AIM: ATOM), the leading low-carbon fertiliser developer and the UK's only dedicated international industrial scale low-carbon fertiliser company, is pleased to announce that it has selected Sungrow Hydrogen as its electrolyser supplier for the flagship 260,000 tonne-per-year low-carbon fertiliser project at Villeta, Paraguay ("Villeta" or "the Project").

Electrolyser Supply for Villeta

Following a rigorous competitive tender process managed by Casale S.A., ATOME's EPC partner for the Villeta Project, ATOME has selected Sungrow Hydrogen ("Sungrow") as the electrolyser technology partner for the Villeta Project. Sungrow Hydrogen is a globally leading supplier of electrolysers.

The Villeta Project will deploy 110MW of Sungrow's proven alkaline electrolyser technology, powered by 100% renewable baseload hydropower from the Itaipu Dam, to produce the green hydrogen required for the production of 260,000 tonnes per year of low-carbon Calcium Ammonium Nitrate fertiliser. The supply will be complemented by a Long-Term Service Agreement to provide maintenance support for the equipment.

The selection of Sungrow as the electrolyser partner at Villeta marks the start of what ATOME and Sungrow expect to be a long-term strategic partnership with further cooperation on other projects already in discussion.

The strategic partnership with Sungrow, as well as the direct investment in ATOME's share capital by Casale and Baker Hughes, reflects the Company's strategy to be able to offer new projects and investments a one-stop-shop solution complemented by ATOME's excellent relations with its funding partners in Villeta.

About ATOME

ATOME PLC is an AIM-listed company targeting green fertiliser production with 445-megawatt of projects in Paraguay and a further pipeline of potential projects in Central America. ATOME has now created its ATOME POWER division which is in the early stages of developing a significant green power generation and infrastructure business. ATOME's projects are situated at the heart of one of the world's largest food export hubs - the Mercosur region in the Southern Cone of South America with the Argentinian and Brazilian markets next door. ATOME's production will disrupt the region's heavy dependence on imported fossil fuel generated fertilizer, contributing to regional food security goals.

ATOME's first project in Villeta, Paraguay, benefits from a 125MW renewable power purchase agreement and a 30-hectare site in a tax-free zone, Front End Engineering Design studies have been completed and a 10-year Definitive Offtake Agreement signed with Yara International, the leading international fertiliser company, for offtake of all of Villeta's green fertiliser production, as well as a US$465 million fixed-price EPC contract with leading ammonia and fertiliser engineering specialist Casale S.A. ATOME declared unconditional Final Investment Decision on the Villeta Project in May 2026 following completion of US$665 million project finance with construction to commence in 2026.

All power for ATOME is from 100% renewable sources and all chosen sites are located close to the power and water sources and export facilities to serve significant domestic and then international demand. Roughly a third of human caused GHG emissions is linked to food production according to UN data, and fertiliser use and production is the source of more emissions than the shipping and aviation industries combined. ATOME's green Calcium Ammonium Nitrate product will contribute to decarbonising the food sector from the bottom up, getting to the root of the food value chain's emissions. ATOME's renewably generated fertiliser is both low-carbon and provides a secure, stable alternative product not reliant on fossil fuels, unlike all nitrogen fertilizer production today.

The Company has a green-focused Board which is supported by major shareholders including Peter Levine, Schroders, a leading fund manager, Baker Hughes, a global technology company operating in the energy and industry sectors and Casale, the Swiss-based ammonia and fertiliser specialist engineering firm and technology licensor
