Operational Update:

Partial Sale of Net Smelter Return Royalty

Aterian Plc
("Aterian" or the "Company")

Aterian Plc (LSE: ATN), the critical metal-focused exploration and development company, announces the sale of its portion of the Net Smelter Return Royalty ("NSR") over the HCK Project in the Republic of Rwanda ("Rwanda") for a £200,000 gross consideration.

The Company has signed an agreement to sell a interest of 1.40 % of the Rio Tinto Joint Venture NSR to Elemental Altus Royalties Corporation ("Elemental Altus"). This royalty reduces to 1.25% upon the Musasa licence being issued in Rwanda. The Company engaged strategic advisors, Collingwood Capital Partners AG, to approach several royalty companies to gain expressions of interest in purchasing the NSR and to provide third-party oversight in the sale of the NSR to Elemental Altus, who provided the best option for the Company.

Charles Bray, Chairman of Aterian, commented:

"The sale of the Rwandan royalty interest to Elemental Altus aligns with our overarching strategy of prioritising financial discipline, strengthening the balance sheet and maximising shareholder value.  We want this to be the first of many new asset value realisation efforts across our portfolio. We believe that this transaction, marking the first royalty sale in Rwanda, positions us for continued success in a challenging market environment, enabling us to capitalise on our portfolio assets and deliver sustainable long-term growth."
