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 is in the early stages of developing a significant green power generation and infrastructure business.

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 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.

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.
