Tietoevry Corporation      INSIDE INFORMATION     12 February 2026   8:55 a.m. EET

Tieto's Board of Directors has resolved to commence a share buyback programme of EUR 150 million. The purpose of the buyback programme is to maintain an efficient capital structure of the company in line with the company's capital allocation principles.

The buyback programme utilizes the authorization granted by the company's Annual General Meeting 2025, under which the Board of Directors is currently entitled to decide on the repurchase of a maximum of 11 585 000 shares, corresponding to approximately 10% of all shares in the company. The company has unrestricted equity available for the repurchase of its own shares.

Following the closing of the divestment of Bekk Consulting AS, the company has the opportunity to distribute proceeds from the divestment through a share buyback programme while remaining within its leverage target (net debt / EBITDA below 2.0).

The share buyback programme will be carried out on the following main terms:

• Amount to be used: EUR 150 million
• Purpose of the repurchases: to maintain an efficient capital structure in accordance with the company's capital allocation principles
• Duration: From 13 February 2026 at the earliest and end by 31 March 2027 at the latest
• Price: market price formed in public trading on Nasdaq Helsinki
• The shares will be repurchased on Nasdaq Helsinki Stock Exchange
• The repurchased shares will be cancelled on a monthly basis

The share buyback programme will be implemented in accordance with the safe harbour arrangement of EU Market Abuse Regulation (MAR). The company has appointed Nordea as the independent financial intermediary to carry out the share repurchases. Intermediary will make all trading decisions regarding the timing of the purchases independently of the company, subject to the terms of the programme and applicable regulation. The repurchase of shares may be temporarily paused, suspended or terminated before the scheduled end date. In such cases, the company will announce the matter in a stock exchange release. The company will publish a stock exchange release reporting the transactions carried out under the programme on a daily basis.
