Delisting from the Oslo Stock Exchange (proposal)

Background on potential delisting from the Euronext Oslo Stock Exchange

The Board of Directors of Tietoevry Corporation (“Tieto” or the “company”) has proposed that the Annual General Meeting 2026 resolves to approve the delisting of the company's shares from the Euronext Oslo Stock Exchange (“Oslo Stock Exchange”), where the company’s shares have been listed as a parallel listing since 2019. The company has concluded that delisting from the Oslo Stock Exchange would be in the best interests of the company and its shareholders.

If the AGM to be held on 24 March 2026 resolves to approve the proposed delisting, the company plans to file an application for delisting of its shares from the Oslo Stock Exchange. Tieto's shares will continue to be traded on Nasdaq Helsinki without interruption.

The registration of the company’s shares will continue to be maintained in the Norwegian central securities depository (Euronext Securities Oslo, formerly VPS) for a transitional period of at least 12 months from the date of delisting to enable shareholders to convert their shares to the Finnish book-entry system maintained by Euroclear Finland. During this period, shareholders’ rights, including, among others, the right to receive dividends, remain unchanged.

Shareholders on the Oslo Stock Exchange can find information on this website and will be provided with timely information regarding the delisting process and timing.

Alternatives to shareholders on the Oslo Stock Exchange

If you wish to keep your Tieto shares

Shareholders wishing to keep their shares in the company following a potential delisting are recommended to consider converting their shares registered on the Norwegian central securities depository (Euronext Securities Oslo) system to Euroclear Finland for Tieto shares listed on Nasdaq Helsinki. By converting shares to Euroclear Finland, you ensure that your Tieto shares will continue to be tradeable after the listing on Oslo Stock Exchange potentially ends.

If you wish to convert your shares, please contact your custodian/account operator. There will be no automatic conversion to Euroclear Finland. The conversion will entail an estimated cost of NOK 1,500 per conversion event that Tieto is planning to cover on behalf of the shareholders if the AGM resolves to approve the proposed delisting. Tieto will cover this conversion cost to shareholders for one conversion per account from 1 April 2026 to 31 December 2026. Please note that shareholders may be responsible for potential additional costs charged by their own custodian/account operator. Please contact your custodian / account operator for further information.

If you wish to sell your shares in Tieto

Shareholders may trade and sell their Tieto shares on the Oslo Stock Exchange until the potential delisting is effective (such date will be informed to shareholders well in advance).

If you wish to sell your Tieto shares after the potential delisting, you will first need to convert your shares to Euroclear Finland for Tieto shares listed on Nasdaq Helsinki. There will be no automatic conversion to Euroclear Finland.

How can I convert my shares to Euroclear Finland (Tieto shares listed on Nasdaq Helsinki)?

Tieto's shares can be converted from Norway to Finland i.e. between the Norwegian Central Securities Depository (Euronext Securities Oslo) in Norway and Euroclear Finland. Shareholders who wish to transfer a position between the two markets should contact their custodian/account operator in Norway who will inform the shareholders on what is required to convert the shares. The conversion will entail an estimated cost of NOK 1,500 per conversion event that Tieto is planning to cover on behalf of the shareholders if the AGM resolves to approve the proposed delisting. Tieto will cover this conversion cost to shareholders for one conversion per account from 1 April 2026 to 31 December 2026. Please note that shareholders may be responsible for potential additional costs charged by their own custodian/account operator. Please contact your custodian / account operator for further information.

Information to custodians

Custodians, you can contact Nordea in Norway at issuer.ops@nordea.com for conversions. Please note that it is the custodian, not the shareholder, who can instruct Nordea for the conversion.

Information to shareholders on Nasdaq Stockholm

As announced on 12 February 2026, Tieto’s Board of Directors is also considering the potential delisting of Tieto’s shares from Nasdaq Stockholm.
