SPAREBANK 1 ØSTLANDET TO EXPLORE THE OPPORTUNITY TO ACQUIRE OWN EQUITY CAPITAL CERTIFICATES

SpareBank 1 Østlandet ("the Bank”) has engaged SB1 Markets AS (the "Manager") to explore the opportunity to acquire equity capital certificates ("ECCs") in the Bank for up to NOK 9 000 000 ("the Offer"). The ECCs will be used in the Bank's savings programme for employees and will be distributed to employees who qualify in reference to the savings programme. Reference is made to the stock exchange announcement published by the Bank on 9 December 2025 for further information on the savings programme, and reference to the stock exchange announcement by the Bank on 26 March 2026 with the general meeting's consideration of a power of attorney to acquire its own ECCs. The Bank’s holding of ECCs is currently 347.

The Offer is carried out through a reverse book-building process. The Manager will gather and accumulate sales orders from existing ECC holders. Once a sales order is placed, it cannot be withdrawn or changed by the selling ECC holder and the selling ECC holder is bound to sell the offered ECCs to the Bank on the offered terms if and at such time the Offer is accepted by the Bank, irrespective of whether the Bank decides to purchase a lower amount of ECCs from a selling ECC holder than offered for sale by the respective ECC holder. The final purchase price per ECC will be set based on the sales orders received at a level representing a satisfactory price and offering volume (to be determined by the Bank at its sole discretion). The final purchase price will be identical for all selling ECC holders.

The book-building period commences immediately and is expected to close at 16:00 hours (CET) on 20 August 2026. The book-building period can be changed at the Bank’s and the Manager's sole discretion. If the transaction is to be completed, pricing will follow shortly after the book-building period. Based on the above closing time, allocation is expected to be made on 20 August 2026 (T), and settlement is expected to take place on or about 24 August 2026 (T+2) through a delivery versus payment (DVP) transaction. If the book-building period is changed, the dates will be adjusted correspondingly.

In the event that the total number of received sales orders at the final purchase price exceeds the number off ECCs the Bank wishes to purchase (or such decreased number of ECCs the Bank wishes to purchase), the allocation will, to the extent possible, be made on a pro rata basis based on the volume offered by each selling ECC holder with the objective of treating all ECC holders equally based on their indicated interest in participating in the Offer at the final purchase price. The Bank reserves the right to, at any time, terminate and not complete the Offer or make any amendments with regards to the volume or other terms of the Offer.

Holders of ECCs wishing to participate in the Offer may contact Eivind Julin in SB1 Markets AS at: Dir. tel.: +47 24 13 37 71, Mob.: +47 976 62 769, e-mail: eivind.julin@sb1markets.no
