1. Employee share savings program Reference is made to prior stock exchange notices regarding the Employee Share Savings Program. Under the terms of the Program, participating employees may allocate a fixed amount of their monthly after-tax salary to purchase shares in Atea ASA (up to a maximum per month of NOK 1,000 in Norway, SEK 1,000 in Sweden, DKK 700 in Denmark and EUR 100 per month in Finland and the Baltic countries). The price of the shares purchased is determined based on the volume-weighted average price of the ATEA share on the day preceding the share transfer. As an additional incentive, participating employees will receive one "bonus" share for each two ordinary shares purchased under the Program after a vesting period in which the specified ordinary shares must be held. The vesting period is three years for executive management and two years for all other employees. The participant must also remain employed by Atea during the vesting period in order to receive the bonus share.  The "bonus" share is treated as a restricted stock unit (RSU) under IFRS 2 Share-Based Payment. On 11 February 2025, 3,211 employees in the Atea group purchased a total of 62,235 shares in Atea ASA at a share price of NOK 148.04 per share, corresponding to the volume-weighted average share price on 10 February 2025. Furthermore, non-executive employees participating in the Program received the right to bonus shares after having held shares for the required vesting period. As a result, 25,371 shares have been transferred from Atea's treasury holdings to employee accounts. 2.
