Bigbank AS (registry code 10183757, address Riia tn 2, Tartu, 51004) (“Bigbank”) hereby announces a public offering (the “Offering”) of its unsecured subordinated bonds. The Offering is conducted pursuant to the prospectus (the “Prospectus”) prepared by Bigbank and approved by the Estonian Financial Supervision and Resolution Authority (“EFSA”) on 9 November 2026. The Prospectus, which provides further details, has been disclosed on the date of this announcement on the websites of Bigbank and the EFSA. 

The bonds will be issued under Bigbank’s unsecured subordinated bond programme (the “Programme”). Through the Offering, Bigbank aims to raise up to 15 million euros, with the option to increase the amount to up to 25 million euros. Under the Programme, Bigbank may raise a total of up to 80 million euros. 

Main terms of the Offering

During the Offering, Bigbank will offer up to 15,000 unsecured subordinated bonds titled “EUR 6.50 BIGBANK SUBORDINATED BOND 26-2036,” each with a nominal value of 1,000 euros and a maturity date of 26 November 2036. The bonds bear interest at a fixed rate of 6.5% per annum, calculated on a 30/360 basis, from 26 November 2026. Interest payments are scheduled for 15 March, 15 June, 15 September and 15 December, with the first interest payment on 15 March 2027. In the event of oversubscription, Bigbank has the right to increase the number of bonds offered by an additional 10,000 bonds, bringing the total amount offered to up to 25,000 bonds. Bigbank also reserves the right to cancel the Offering for any portion of the bonds that are not subscribed. The bonds are offered at a price of 1,000 euros per bond. The bonds will be registered in the Estonian Register of Securities, operated by Nasdaq CSD Estonian Branch (“Nasdaq CSD”), under ISIN code EE0000005510. 

The subscription period for the bonds will begin on 10 November 2026 at 10:00 and end on 20 November 2026 at 15:30 (Tallinn time). The Offering will be directed to both retail and professional investors in Estonia, Latvia and Lithuania. The public offering of the unsecured subordinated bonds will be conducted exclusively in Estonia, Latvia and Lithuania, and not in any other jurisdiction. 

A subordinated bond represents an unsecured debt obligation of Bigbank to the investor. The subordination of the bonds means that, in the event of liquidation or bankruptcy of Bigbank, claims arising from the subordinated bonds will only be settled after the full satisfaction of all unsubordinated, recognised claims, in accordance with applicable law. Additionally, holders of subordinated bonds must consider the risk of write-down or conversion of liabilities and claims (bail-in risk).  

In allocating the bonds, Bigbank reserves the right, but not the obligation, to give preference over other investors to customers who hold a current account with Bigbank in their own name as at 18 November 2026. If mathematically possible, each retail investor will be allocated at least two bonds with a total nominal value of 2,000 euros. Further details of the allocation are set out in the Prospectus. 

Specific details of the Offering are set out in the Prospectus and the Prospectus Summary.
