KR1 plc (the "Company')

Admission to the Main Market and First Day of Dealings

KR1 plc (LSE: KR1), a leading digital asset technology company, is pleased to announce the admission of its entire share capital, being 177,949,520 ordinary shares (including 363,000 held in treasury) of £0.0019 pence each ("Ordinary Shares"), to trading on the Main Market of the London Stock Exchange and to the Equity Shares (Commercial Companies) category of the Official List of the FCA ("Admission").

The Company's Ordinary Shares ceased trading on the Apex segment of London's AQSE Growth Market on 24 November 2025. Admission and dealings in the Ordinary Shares will commence at 8.00 a.m. today, 25 November 2025, under the ticker "KR1" and ISIN IM00BYYPQX37.

A copy of the prospectus published in connection with Admission (the "Prospectus") can be accessed on the Company's website at www.KR1.io and at the National Storage Mechanism at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.

Reasons for the Admission to the Main Market

The admission to the Main Market is a natural progression of the Company's business model and strategic development and it is the Board of Directors' belief that Admission will have the following benefits:

● the Company will have access to a larger pool of capital, which may improve the liquidity of the Ordinary Shares; ● it is expected to facilitate a broadening of the Company's share register, with a particular focus on attracting non-retail and institutional investors; ● it may enable the Company to be eligible for inclusion in the FTSE UK Index Series which may further facilitate increased liquidity; ● it may help to raise the Company's profile with increased media coverage and investor interest, which in turn would enhance its status and could potentially increase analyst coverage; and ● the Company will be required to comply with higher standards of governance required by listed companies under the UK Listing Rules.

Strategy

The Company's strategy is to expand its existing staking operations through compounding the digital assets it generates, acquiring additional staking assets, investing in companies and assets in the digital asset sector and potentially entering into relevant partnerships or joint ventures.

The Company has also established a placing programme to issue up to 125,000,000 new Ordinary Shares to, in time, expand the Company's existing staking operations in line with its business strategy (the "Placing Programme").

George McDonaugh and Keld van Schreven, Managing Directors and Co-Founders of KR1 plc, said: "We are delighted to announce the admission of KR1 plc to the Main Market of the London Stock Exchange today. This represents a significant step in our mission to provide credible, institutional-grade exposure to digital assets and decentralised technologies on London's public markets.

"The listing is expected to expand the Company's shareholder base and support our growth ambitions. The UK is playing an increasingly important role within the rapidly evolving digital assets sector and KR1 plc is proud to contribute to that progress. We look to the future with optimism and confidence."

The Directors of KR1 plc accept responsibility for this announcement.
