Byggmax has a strong financial position. Despite investments in organic growth and dividends to shareholders, the cash flow from operations has further strengthened the Company's position compared to the same time last year (end of the third quarter). The introduction of a share buy-back program aims to adapt the Company's capital structure and contribute to increased shareholder value. Byggmax will also after the repurchase of own shares have a strong financial position that enables the Company's growth strategy going forward. The board intends to continuously evaluate how the Company's capital structure can be adapted to contribute to increased shareholder value. In addition to dividends in accordance with the dividend policy, it is the board's long term ambition to carry out further repurchases of its own shares.

The buy-back program is being carried out in accordance with the Market Abuse Regulation (EU) No 596/2014 ("MAR") and the Commission Delegated Regulation (EU) No 2016/1052 (the "Safe Harbour Regulation"). The buy-back program will be managed by an investment firm or credit institution that makes its trading decisions regarding the timing of the buy-backs of the Company's shares independently of and without influence from Byggmax.

The buy-back program is subject to the following conditions:

• The amount paid for acquired shares may not exceed SEK 60 million in total.
• A maximum of 2,931,252 shares may be acquired.
• Acquisition of shares may be carried out from October 26, 2026 to the date of the 2027 annual general meeting.
• Acquisition of shares shall take place on Nasdaq Stockholm and take place in accordance with the rules concerning the purchase of own shares set out in Nasdaq's Nordic Main Market Rulebook for Issuers of Shares, and in accordance with MAR and the Safe Harbour Regulation.
• Acquisition of shares on Nasdaq Stockholm shall be made at a price per share within the registered interval for the going rate at any given time, which denotes the interval between the highest purchase price and the lowest selling price.
• In accordance with the authorization from the 2026 annual general meeting, the Company's holding of own shares may not exceed five percent of the Company's outstanding shares.
• Payment for the shares must be made in cash.

It is the Board's intention to propose that the repurchased shares will be withdrawn through a reduction in the share capital.

Reporting will take place to Nasdaq Stockholm in accordance with current rules. The transactions will also be published on the Company's website.

The Company's current holding of own shares is 0. The total number of outstanding shares in the Company is 58,625,045.
