DIGITAL 9 INFRASTRUCTURE PLC

("D9" or the "Company")

Announcement of Compulsory Redemption

The Company announces that, in connection with the first compulsory pro rata redemption of its Ordinary Shares, as announced on 15 April 2026 (the "Redemption"), at the close of business on 16 April 2026 (the "Redemption Date"), 323,402,288 Ordinary Shares were redeemed on a pro rata basis at a redemption price of 9.2753 pence per Ordinary Share. The Ordinary Shares redeemed represented approximately 37.38 per cent of the Company's Ordinary Shares in issue as at the Redemption Date.

Fractions of Ordinary Shares were not redeemed and, accordingly, the number of Ordinary Shares redeemed in respect of each shareholder was rounded down to the nearest whole number of Ordinary Shares. All Ordinary Shares redeemed pursuant to the Redemption have been cancelled.

Redemption monies due to shareholders will be transferred to the Company's registrar, Computershare, on 27 April 2026 and will be paid through CREST or, in the case of certificated holdings, by cheque. The latest payment date is expected to be 30 April 2026. Shareholders' existing Ordinary Share certificates will be cancelled and new Ordinary Share certificates will be issued to certificated shareholders in due course

The new ISIN, JE00BPH3HM76 (the "New ISIN"), representing the remaining Ordinary Shares which have not been redeemed, will be enabled and available for transactions after 8.00 a.m. today. CREST will automatically transform any open transactions as at the Redemption Date into the New ISIN.

Following the Redemption, the total number of Ordinary Shares in issue will be 541,772,666. Therefore, the total number of voting rights in the Company will be 541,772,666. This figure may be used by shareholders as the denominator for the calculations by which they determine whether they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

Capitalised terms used but not defined in this announcement have the meanings given to them in the Circular.

ENDS.
