Aterian Plc

("Aterian" or the "Company")

Additional Funding to Secure Growth

Aterian plc (LSE: ATN), the critical mineral exploration and development
company, is pleased to announce it has successfully secured US$325,000 of
mezzanine funding to support general operations and expand trading activities
in the Republic of Rwanda ("Rwanda"), with a focus on the acquisition and sale
of tantalum-niobium ("Coltan") concentrate.

The funding is being advanced alongside the Company's partnership with a
leading metals and minerals trading house with a global presence. This
collaboration enables the Company to scale rapidly and position itself as a
significant supplier of responsibly sourced Central African minerals.

To complement this funding, Aterian has issued 1.043 million warrants to the
mezzanine funding investors following the expiry of 0.50 million outstanding
warrants, providing investors the opportunity to participate in the Company's
growth trajectory. The newly issued warrants have a 40 pence exercise price
and expire 30 December 2027.

Chairman's Statement - Building Momentum

Charles Bray, Executive Chairman of Aterian, commented:

"This funding marks yet another a very exciting milestone for Aterian and our
trading business. Not only does it strengthen our working capital, but it also
unlocks the ability to accelerate growth and broaden our reach to a network of
world-class downstream buyers.

We are now entering a new chapter where Aterian is not only an exploration
company but also an active and growing trading business. Our rigorous focus on
traceability, ESG compliance, and supply chain integrity provides us with a
strong competitive edge. This is the beginning of what I believe will be a
transformative period for the Company, and I look forward to updating
shareholders as we build further momentum across our portfolio."
