Villeta discussions update

ATOME (AIM: ATOM), the only international industrial-scale green fertiliser project development company on the London Stock Exchange, with large-scale projects in Latin America, announces that further to the announcements of 10 June 2026 and 19 June 2026, ATOME is continuing its engagement with the relevant authorities in Paraguay and ANDE, the state-owned electrical distribution entity, with regards to the Power Purchase Agreement necessary for the Villeta Project.

Peter Levine, Chair, said:

"ATOME, in good faith, continues to take steps to seek a mutually acceptable amicable resolution to the matter with ANDE to put the nationally strategic and fully funded Villeta Project on track where all is ready to start immediate building works.

Directly supporting discussions with ANDE, ATOME is pleased to carry with it the goodwill and active participation of its lenders, IDB Invest, the private sector arm of the Inter-American Development Bank Group consisting of 48 country members, IFC - the private sector arm of the World Bank Group, the European Investment Bank, and FMO - the Dutch Development Bank. Both IDB Invest and EIB provide support and financial assistance to ANDE.

 ATOME relied at all times in continuing with its investments on the Presidential Decree, signed on 16 January 2026 where the Power to X regime was created, which was unexpectedly revoked earlier this month, together with the concrete and specific assurances of the President, who remains with his administration great supporters of the Project.

It has been reported that ATOME's Villeta Project is the only real major industrial investment in the whole of Paraguay which will have a material impact on job creation and the Country's GDP value with crypto mining having almost zero and AI a low impact with the latter still several years away from materialising. Villeta is wholly aligned with the goals set out by the President in creating substantial inward investment for new industries which can directly benefit the country as the largest single industrial investment in the history of Paraguay and one which will create directly and indirectly 4,000 jobs during construction and over 1,000 jobs during production, serving Paraguay's people, land and farmers and the Mercosur region and generating jobs in a completely new industry for the long-term.

Villeta is estimated to provide ANDE with over US$1 billion of revenue during its project life which Paraguay will lose to another country if the project does not go ahead. The project is exactly in line ANDE's published Mission Statement which states that: "The mission of ANDE is…to participate in the regional electricity sector, with socio-environmental responsibility, in order to contribute to the development of Paraguay and the wellbeing of the population".

We have formally communicated with ANDE that we intend to discuss the issues with them with a view to resolving the matter expeditiously and fairly to all sides, allowing time for the parties to reach an amicable conclusion."

Paraguay press comment

ATOME also notes that late in the evening on Friday 26 June it received communication from ANDE, subsequently leaked to the Paraguay media (not by ATOME), rejecting a now outdated and superseded proposal by ATOME of November 2025. This information is not new and ATOME has already informed the market of the recently arising issues in the announcement made on 10 June and 19 June 2026.

As acknowledged by ANDE, without prejudice or limitation to the Company's position, ATOME in any event currently has a 145MW power purchase agreement initially entered into in 2022 (PPA), under which power is reserved exclusively for ATOME. The January 2026 Presidential Decree (Decree) stipulated a revised tariff structure and term length for an intended replacement PPA with the other terms of that replacement having been successfully negotiated with ANDE since the date of the Decree.
