Update on Asset Sales, Bank Facility Amendment and Board Changes

Sutton Harbour is pleased to announce that it has completed two further asset disposals, an amendment to its bank facility and board changes.

Property Sales

The Company has completed the sales of two further Sutton Harbour assets, being for aggregate gross proceeds of £2.675m and achieving 80% of the independent valuations as at 31 March 2024, before selling costs. From the net proceeds received by Sutton Harbour, £2.190m has been paid to reduce the Company's bank loan to £18.065m.

The Company continues to actively manage its asset sale programme in order to further reduce the bank loan and will provide further updates in due course.

Bank Facility Amendment

National Westminster Bank plc has agreed to a further extension to the repayment dates of the Company's bank loan to allow asset sales to complete and additional bank loan repayments to be made. Further to the Company's announcements of 20 January 2025 and 21 March 2024, the amended bank loan agreement requires £6.5m to be repaid by 30 September 2025 , thereby reducing the bank loan to £11.565m from the disposal of assets,  including King Point Marina. The facility's maturity date remains as 30 December 2026.
