DIGITAL 9 INFRASTRUCTURE PLC

("D9" or the "Company")

Announcement of First Compulsory Redemption and Timetable

The Company announces that, further to the approval by shareholders at the General Meeting held on 12 March 2026 and as contemplated in the shareholder circular published on 20 February 2026 (the "Circular"), the Board has approved the first compulsory pro‑rata redemption of the Ordinary Shares in the Company (the "Redemption").

Key details of the Redemption

The Redemption will be carried out on a compulsory pro‑rata basis across all shareholders on the Redemption Record Date. All Ordinary Shares will be treated equally and no shareholder action is required.

Fractions of Ordinary Shares will not be redeemed and, accordingly, the number of Ordinary Shares redeemed in respect of each shareholder will be rounded down to the nearest whole number

As set out in the Circular, the Board has discretion to determine the Redemption Price within the framework approved by shareholders, having regard to prevailing market conditions and subject to the Redemption Price not exceeding the Net Asset Value per Ordinary Share.

At the time the Circular was published, the Company's most recently published NAV was materially above the prevailing market price. Following publication of the updated NAV of 9.2753 pence per Ordinary Share, the Board considers it appropriate to determine the Redemption Price at 9.2753 pence per Ordinary Share.

The aggregate amount to be returned to shareholders pursuant to this first compulsory redemption is equivalent to approximately 3.5 pence per existing Ordinary Share. This will be funded from available cash resources following recent asset realisations, including the settlement relating to Verne Global, and after taking account of the Company's ongoing obligations and working capital requirements.

ISIN arrangements

In connection with the Redemption, the existing ISIN for the Ordinary Shares will expire on 17 April 2026, being the Ex‑Date. The new ISIN, JE00BPH3HM76, representing the remaining Ordinary Shares following the Redemption will be enabled on the same date. All relevant transformations will be processed automatically through CREST.

Settlement and payment

The Redemption will be implemented through the redeemable share mechanism described in the Circular. Cash payments due to shareholders will be funded to the Company's registrar, Computershare, on 27 April 2026 and will be paid via CREST or, in the case of certificated holdings, by cheque. The latest payment date is expected to be 30 April 2026.

Further information

The Redemption forms part of the Company's Managed Wind‑Down and follows recent asset realisations, including the settlement relating to Verne Global. The Board will continue to assess the timing and size of future redemptions as additional cash becomes available, having regard to the Company's ongoing obligations and solvency requirements.

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

ENDS.
