John Mattson was listed on the stock exchange in 2019 and has since then never carried out any value transfer to its shareholders through dividend, share repurchase, or redemption of shares in the Company. Based on the market conditions that have previously prevailed, the Board of Directors of the Company has assessed that reinvestment of all cash flow into John Mattson's operations has provided the Company with the best conditions to achieve its financial targets within the framework of its financial risk limitations.

Based on the current market conditions, the Board of Directors of John Matsson assesses that continued investments primarily in apartment upgrades and energy efficiency, in combination with share repurchases, increase the Company's ability to meet its financial targets. Together with the adjustment and improvement of the Company's capital structure that the share repurchases result in, this is overall assessed to contribute to creating additional value for the Company's shareholders.

The group's financial position is assessed to remain strong even after the decided share repurchases have been carried out, providing John Matsson with financial flexibility to continue developing the business according to the established strategy.

The Board of Director's resolution concerns share repurchases of up to a total amount of SEK 100 million during the period from 23 October 2025 up until the Annual General Meeting 2026. Repurchases may only be carried out on Nasdaq Stockholm within the price range registered at any given time between the highest bid price and the lowest ask price and otherwise in accordance with Nasdaq Stockholm's Rulebook for Issuers.

The total number of shares in the Company as of the date of this press release amounts to 75,793,930. As of the same date, John Mattson does not hold any own shares.

John Mattson has engaged DNB Carnegie Investment Bank AB (publ) as financial advisor and Wigge & Partners Advokat KB as legal advisor in connection with the share repurchases. Reporting of completed repurchases will be carried out in accordance with applicable regulations.
