Green Climate Fund approves US$50 million in concessional finance to Villeta Project

ATOME (AIM: ATOM), the leading developer of international green fertiliser projects, is pleased to announce that the Green Climate Fund ("GCF"), the world's largest climate fund, has approved US$50 million of concessional finance for the Villeta Project ("the Project").

Highlights

·   The Board of GCF has approved US$50 million of concessional finance for the Project, through the  International Finance Corporation, part of the World Bank Group, as Accredited Entity

·    This finance is in addition to the senior debt financing package to be provided by a consortium of leading international development finance institutions

·    GCF is the world's largest climate fund, with a current portfolio of approximately US$18 billion invested in various projects around the world

·     The concessional finance reduces the Project's cost of capital and supports market competitiveness

·   GCF views the Project as a large-scale catalytic step towards decarbonising fertiliser production across South America and importantly will contribute to the sustainability, affordability and security of the food supply chain

Olivier Mussat, CEO, commented:

"The Green Climate Fund's board approval of significant concessional finance is a powerful validation of the Villeta Project's credibility, ambition, and alignment with global sustainability goals.

"This highly competitive funding, alongside competitive senior debt support from leading multilateral development institutions, will meaningfully lower the overall cost of capital. By enhancing the value of the equity component, it importantly enhances the bankability and value of the Project equity and will assist in optimising returns for ATOME's shareholders.

"With daily momentum building on the US$630 million Villeta Project, we are advancing confidently toward a Final Investment Decision in the coming months."

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 43 hectares of land in a tax-free zone. Front End Engineering Design studies have been completed and Heads of Terms 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.
