ATOME ENERGY PLC

("ATOME" or the "Company")

Admission to Trading on AIM

First day of dealings

ATOME has received the prestigious London Stock Exchange's Green Economy Mark

ATOME Energy (AIM: ATOM), the international company focused on green hydrogen and ammonia production, sales and marketing with current projects in Iceland and Paraguay, is pleased to announce that its entire issued ordinary share capital will today be admitted to trading on the AIM market of the London Stock Market ("Admission"). Dealings will commence at 8:00 a.m. today, Thursday 30 December 2021, under the ticker "ATOM" (ISIN: GB00BP4BSM10). The Company's SEDOL is BP4BSM1. The Company's Admission Document can be viewed at the website of the Company at www.atomeplc.com.

ATOME, as the first and currently only company solely focusing on being a producer of green hydrogen and ammonia to have its shares traded on the London Stock Market, offers investors access not only to potential upstream manufacturing of green hydrogen and ammonia but also through its established in country contacts and shareholder base to the all-important downstream offtake market.

The Directors believe that ATOME has through its carefully planned and implemented business model a significant opportunity to fast track and be at the forefront of the international development of green hydrogen and ammonia as future fuel.

Green hydrogen and ammonia are an essential part of the matrix of renewable energy sources to decarbonise the global economy where they can address hard to abate carbon footprints of industries such as heavy transport, marine and steel and concrete manufacturing as well as enabling the large-scale production of green fertilisers. As such they have been referred to as the swiss army knife of energy providing multiple solutions in sectors where renewable alternatives such as rechargeable batteries have no answer.

In addition to being a valuable part of the armoury in decarbonisation, with the recent significant increase in the prices of fossil fuels which are still used to generate over 95% of hydrogen current production, ATOME's green projects are expected to have significant potential end market cost benefits; one example being in agriculture where ammonia a key component in fertilisers has doubled in price over the last twelve months to over US$1,000 per tonne due directly to the substantial rise in the cost of natural gas.

The Company has accordingly selected its projects to take advantage of available low-cost pure green power in sufficient amounts so as to build businesses of scale in fiscally benign countries with not only domestic demand but which are also located within international trading blocks. ATOME has targeted commencement of production for the first part of 2024 and expects to benefit in the future from the projected reduction in the price of electrolyser and other manufacturing equipment used in the production process combined with the advent of new technologies offering greater economies with an increasing number of suppliers coming into the market providing greater choice and competitive tension for the benefit of purchasers of such equipment.

Key points

Oliver Mussat, CEO of ATOME Energy, commented:

"Today marks an important milestone for both ATOME and the London market's place in the transition to a green economy. ATOME is the first dedicated and currently only company targeting green hydrogen and ammonia production to have its shares traded on London Stock Market, with both commodities expected to play a key role in the decarbonisation of future energy supply.

"We are proud of the award of London Stock Exchange's Green Economy Mark. This prestigious classification represents our commitment as a company to meaningfully mitigate the impacts of climate change and is a clear message to our investors and other stakeholders of the commitment of ATOME in supporting the transition to net zero.

"We have assembled a green-focused Board whose complementary skills and experience across the energy value chain demonstrate that we can deliver these projects. Both Board and management made a material contribution to the fundraise and are thus fully aligned with our new investors. I would like to thank the Board, along with our advisers and significant shareholders including Peter Levine, our Chairman, Trafigura, one of the world's leading commodity, energy and logistics companies, and fund manager Schroders for their continued guidance and support.

"With the funding secured, ATOME is in a position to rapidly progress its projects in Iceland and Paraguay towards Final Investment Decision (or FID) in both countries. The projects both plan to deliver green energy using mature technology and low-cost baseload power which is available on-tap in both locations. Our projects have government support and accessible markets which need green hydrogen and ammonia to reach their net zero targets, and ATOME is positioned to capitalise on this.

"We have an exciting road ahead as nations implement decarbonisation strategies with green hydrogen and ammonia at their heart. We look forward to updating shareholders on ATOME's progress during 2022 with increasing newsflow as we move towards FID, commencing with a live Investor Meet presentation to which all shareholders, analysts and prospective investors will be invited at a date to be announced in January."
