ATOME (AIM: ATOM), the world-leading low-carbon fertiliser developer and the UK's only dedicated international industrial scale low-carbon fertiliser company, is pleased to note that the Board of the International Finance Corporation ("IFC"), the private investment arm of the World Bank Group, has approved their part of the total financing package for the landmark US$630 million, 260,000 tonne-per-year low-carbon fertiliser plant at Villeta, Paraguay ("Villeta" or "the Project").

Key Points:

·     The IFC Board has approved up to US$100 million total project financing package for the Villeta Project across concessional debt and project level equity.

·      IFC, a member of the World Bank Group, is the largest global development institution focused on private sector investments in emerging markets. In 2024, IFC committed over US$9 billion in long-term climate finance and currently holds approximately US$17 billion in total exposure across Latin America and the Caribbean.

·      As shown in public disclosures, the participants in the Villeta Project's debt finance include IFC, EIB, IDB Invest (Inter-American Development Bank's private investment arm), FMO (the Dutch development bank) as well as the Green Climate Fund.

Olivier Mussat, CEO of ATOME, commented:

"The IFC Board's approval of up to US$100 million of debt and equity financing for Villeta is another strong endorsement of the Project's maturity, bankability, and positive development impact.

"This is another important step towards finalising the US$630 million project funding as we remain focused on achieving FID before the end of the year."

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 145MW renewable power purchase agreement and a 30-hectare site in a tax-free zone, with an option already secured to purchase an additional 13 hectares of adjacent land. 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. In early 2025, ATOME announced Hy24, the leading clean hydrogen asset manager, as anchor and lead equity investor in the project, and confirmed the signing of the US$465 million fixed-price EPC contract with leading ammonia and fertilizer engineering specialist Casale S.A. The Company is now negotiating the project finance with a view to commencing work in 2025. There is a further up to 300MW of renewable power reserved for ATOME in Paraguay.

In Costa Rica, The National Ammonia Corporation S.A. was formed in 2022 with local partner Cavendish S.A. based in Costa Rica to develop green fertiliser projects for the region. As well as straddling the Pacific and Atlantic Oceans, Costa Rica is a democratic Central American country. In agriculture, Costa Rica is the second largest supplier of pineapples in the world and is in the top ten banana growers.

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 clean and promotes high crop yields, unlike conventional nitrogen fertiliser which has a heavy carbon footprint.

The Company has a green-focused Board which is supported by major shareholders including Peter Levine, Schroders, a leading fund manager, and Baker Hughes, a global technology company operating in the energy and industry sectors.
