“Buy-backs are better than dividends when the discount is what it is. It is simple mathematics, says Pål Ahlsén”, CEO of Castellum. 

Acquisitions of shares pursuant to the new share buy-back program will be carried out in accordance with the EU Market Abuse Regulation (EU) No 596/2014 ("MAR") and the Commission Delegated Regulation (EU) 2016/1052 (the "Safe Harbour Regulation"). Acquisitions of shares will be managed by ABG Sundal Collier, that will make its trading decisions regarding the timing of the acquisitions of Castellum's shares independently of Castellum.

The share buy-back program is subject to the following terms:

1. Acquisitions may be carried out only to the extent that Castellum, after each acquisition, will hold a maximum of ten per cent (10%) of all shares issued by the company. The maximum purchase amount is SEK 1.7 billion.
2. Acquisitions shall be made on Nasdaq Stockholm in accordance with Nasdaq Nordic Main Market Rulebook, MAR and the Safe Harbour Regulation.
3. The shares shall be acquired at a price per share within the registered price level on Nasdaq Stockholm at the time of the acquisition, which refers to the level between the highest current purchase price and the lowest selling price published on a regular basis by Nasdaq Stockholm, and acquisitions shall otherwise be conducted in accordance with the rules regarding the price for repurchase of own shares set out in Nasdaq Nordic Main Market Rulebook.
4. Acquisition of shares may be carried out on one or several occasions during the period until Castellum's Annual General Meeting 2027.
5. Payment of the shares shall be made in cash.

The purpose of the acquisition of own shares is to adjust the company’s capital structure, thereby efficiently contributing to an increase in shareholder value.

SEK 1.7 billion is the equivalent of 25 percent of the income from property management for 2025 (SEK 1.2 billion), plus the remaining amount, which has not yet been used for repurchases of shares, of the SEK 3.4 billion which the Board on 20 February 2026 announced that Castellum was going to repurchase shares for following the divestment of properties totaling SEK 5.6 billion.

ABG Sundal Collier has been appointed as Castellum’s advisor in relation to the acquisition of own shares.

At the time of this press release, the total number of issued shares in Castellum amounted to 492,601,452 and Castellum held 25,727,278 own shares, of which 15,075,097 shares will be cancelled in accordance with the Annual General Meeting's resolution.
