DeFi Development Corporation UK PLC

(the "Company")

Update on Warrants

DeFi Development Corporation UK PLC (LSE: DFDV and OTCQB: DFUKF) provides the following update on the warrants, full details of which are set out in the Company's announcement released on 28 August 2025 (which is available on the Company's website at  https://dfdv.co.uk/investor?tab=regulatory-filings)

Background

On 28 August 2025, the Company announced a £2.8 million gross fundraise (the "Fundraise") through a subscription for pre-paid warrants (the "Pre-Paid Warrants") by a group of strategic investors, including DeFi Development Corp (Nasdaq: DFDV) (the "Investors"). Subject to shareholder approval, the Investors were also to receive cash warrants over new Ordinary Shares (the "Investor Warrants" and, together with the Pre-Paid Warrants, the "Warrants").

The Warrants are not capable of exercise until certain conditions have been satisfied ("Conditions"), the original deadline for which was 31 November 2025. Failing this, the Warrants would expire and be cancelled and the deposit for the Pre-Paid Warrants would be repaid (less pre-agreed contributions to transaction costs).

On 4 December 2025, the Company announced the cancellation of 5,000,000 Warrants and an agreement with certain Investors to extend the period for satisfying the Conditions required before the Warrants can be exercised to 1 June 2026

Warrants Extension

The Company is pleased to announce that it has agreed with certain Investors to further extend the period within which the Conditions may be satisfied to 22 June 2026.

Accordingly, the Warrants will only become exercisable once the Conditions have been satisfied on or before 22 June 2026.

If the Conditions have not been satisfied by 22 June 2026, the Warrants will expire and be cancelled, and the Company will have to repay the deposit for the Pre-Paid Warrants to the relevant investors (less pre‑agreed contributions to transaction costs).

The extension enables the Company to continue progressing discussions with relevant stakeholders in relation to its strategic objectives and future development.
