Summa Defence Plc (the "Company") has today agreed on the conversion of the EUR 8.0 million bridge financing loan announced by the Company on 5 June 2026 into a convertible bond. The Company has signed an amended loan agreement with Largus Holding AB, pursuant to which the bridge financing loan is converted into a convertible bond.

The principal amount of the convertible bond is approximately EUR 8.6 million, corresponding to the original EUR 8.0 million principal of the bridge financing loan, to which the accrued unpaid interest prior to conversion into a convertible bond and a six per cent arrangement fee has been added. The convertible bond bears interest at the rate of 14 per cent per annum, and the loan matures for repayment on 31 March 2027.

The Company's Board of Directors has, pursuant to the authorisation granted by the Annual General Meeting held on 24 June 2026, resolved to issue special rights entitling to shares pursuant to Chapter 10 of the Finnish Companies Act to Largus Holding AB in order to implement the conversion right of the convertible bond. Largus Holding AB has the right to convert the principal of the convertible bond and any accrued interest into new shares of the Company at a subscription price of EUR 0.20 per share.

The Company has the right to repay the loan early with the consent of Largus Holding AB, in which case a 10 per cent prepayment fee shall be charged on the early repaid principal. The loan is secured by certain share pledges granted by Summa Holding Oy and Nordic Yards Oy, as well as business mortgages of the Company.
