ATOME PLC

("ATOME" or the "Company")

Delay in publication of Annual Report and Accounts

Temporary suspension from trading on AIM

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 discussions in Paraguay are still ongoing, as detailed in the announcement made on 29 June, and given the material impact of the Villeta Project on the presentation of the Financial Statements, the Board has determined after consulting with its Nominated Advisor to defer the finalisation of the Group Accounts for the year ended 31 December 2025 ("Accounts") pending resolution of the ongoing PPA discussions in a manner that permits the Villeta Project to proceed without unreasonable delay.

Peter Levine, Chair, said:

"As announced on Monday, ATOME, in good faith, continues to take all steps necessary 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. We are focused on resolving this matter expeditiously and fairly to all sides, but allowing time for the parties to reach an amicable conclusion, following which we can then publish the Accounts and return to business as normal. The Board hopes that the delay in publishing the Accounts will not be for a prolonged period and that Shareholders will understand that this is a prudent and proper course of action.

"In this regard, the Company is pleased to report all relevant stakeholders continue to be supportive of ATOME and like ourselves are looking forward to the start of construction.

"Notwithstanding this, all preparatory work on the Villeta Project is continuing as normal and ATOME is in discussions with the EPC contractors to bring forward the build time to ensure the Project is on the original schedule once the notice to proceed for construction is given to the them."

In the meantime, and as the Company was not in a position to publish its Accounts by 30 June 2026 in accordance with AIM Rule 19, the Company's Shares have therefore been temporarily suspended from trading on AIM pending publication of the Accounts. The suspension is with effect from 7.30 a.m. today. Suspension from trading is expected to be lifted with the publication of the Accounts.

A further announcement will be made in due course.
