Final outcome of the Rights Issue

The subscription period in the Rights Issue ended on 18 March 2026. The Rights Issue comprised a maximum of 2 976 000 shares of Class A and a maximum of 50 752 264 units, whereof each unit consists of three (3) shares of Class B and one (1) warrant of series TO 1. One (1) warrant of series TO 1 entitles the holder to subscription of one (1) share of Class B in the Company at an exercise price amounting to SEK 3.10. Subscription of shares of Class B by exercise of warrants series TO 1 shall be made during the period from and including 12 March 2029 up to and including 26 March 2029.

The final outcome shows that 2 976 000 shares of Class A, corresponding to approximately 2 percent of the Rights Issue, have been subscribed for by exercise of subscription rights. Furthermore, 32 746 799 units, corresponding to approximately 63 percent of the Rights Issue, were subscribed for by exercise of unit rights. 7 256 555 units have been subscribed for without exercise of unit rights, corresponding to approximately 14 percent of the Rights Issue. Thus, the Rights Issue is subscribed to a total of approximately 79 percent and guarantee commitments have been utilized with approximately 10 percent of the Rights Issue.

Through the Rights Issue, Wästbygg Group initially receives approximately SEK 191 million before issue costs and repayment of the bridge loan (the repayment amounts to approximately SEK 144 million, including accrued interest). Upon full exercise of all warrants series TO 1 issued as part of the Rights Issue, the Company might receive additional proceeds of up to approximately SEK 124 million in March 2029, before issue costs.

Allotment of shares and units subscribed for without exercise of subscription rights and unit rights

Allotment of shares and units subscribed for without exercise of subscription rights and unit rights has been made in accordance with the principles stated in the press release published by the Company on 13 January 2026, and, with regard to units, in the prospectuses that the Company published on 2 March 2026 and on 6 March 2026 in connection with the Rights Issue (the “Prospectuses”). Notification of such allocation will be made separately though a settlement note. Payment of subscribed and allotted shares and units shall be made through cash payment in accordance with the instructions in the settlement note. Nominee registered shareholders will receive notification on allocation in accordance with instructions from the respective nominee.

Changes in share capital and number of shares as well as dilution

Through the Rights Issue, the total number of shares of Class A in the Company will increase by 2 976 000 shares and the total number of shares of Class B will increase by 120 010 062 shares, which results in that the total number of outstanding shares in the Company increases from 51 744 264 shares to 174 730 326 shares, whereof 3 968 000 are shares of Class A and 170 762 326 are shares of Class B. The share capital increases with SEK 13 665 118,013 from SEK 5 749 362,672 to SEK 19 414 480,685. This corresponds to a dilution effect of approximately 70 percent of the total number of shares in the Company after the Rights Issue.

If all outstanding warrants series TO 1 issued as part of the Rights Issue are exercised in full for subscription of new shares of Class B in March 2029, the total number of shares in the Company will increase by an additional 40 003 354 shares, from 174 730 326 shares to 214 733 680 shares, whereof 3 968 000 are shares of Class A and 210 765 680 are shares of Class B, and the share capital will increase by an additional SEK 4 444 817,115, from SEK 19 414 480,685 to SEK 23 859 298,800, corresponding to a dilution effect of approximately 76 percent of the total number of shares in the Company after the Rights Issue and exercise of warrants series TO 1.

In addition to what is stated above, the potential issue of units as compensation to guarantors may entail additional dilution.

Compensation for guarantee commitments

In connection with the Rights Issue, a number of external investors and current shareholders have entered into guarantee commitments of a total of approximately SEK 90 million. For the guarantees, according to the guarantee agreements, cash compensation is paid with 11 percent of the guaranteed amount, corresponding to a total of approximately SEK 10 million, or 13 percent of the guaranteed amount, corresponding to a total of approximately SEK 12 million in the form of newly issued units in the Company, with the same terms and conditions as for units in the Rights Issue, including the subscription price in the Rights Issue. If all guarantors were to choose to receive guarantee compensation in units, a total maximum of 2 516 131 units containing 7 548 393 shares of Class B and 2 516 131 warrants series TO 1 would be issued as guarantee compensation.

The issue of units as compensation to the guarantors is, if applicable, intended to be resolved upon by the Company's Board of Directors based on the authorization granted by the extraordinary general meeting on 25 February 2026. Information about the issue resolution will, if applicable, be announced through a separate press release.

Trading in BTU and delivery of shares

Trading in paid subscribed units (BTU) is currently ongoing on Nasdaq Stockholm under the short name WBGR BTU B and will cease on 27 March 2026. Thereafter, BTU will be converted into shares of Class B and warrants series TO 1. The shares of Class B and warrants will be admitted to trading on Nasdaq Stockholm as soon as possible after conversion.

Delivery of shares of Class A and shares of Class B will be made as soon as the Rights Issue has been registered with the Swedish Companies Registration Office, which is expected to take place around 26 March 2026.

Resolution on articles of association

The extraordinary general meeting on 25 February 2026 resolved to change the provisions of the articles of association regarding the limits of the Company's share capital and number of shares, and that the Board of Directors would be authorized to register the Company's new articles of association according to one of six options (alternatively not to register any new articles of association at all) based on the outcome in the Rights Issue. Due to the outcome of the Rights Issue, the Board of Directors has decided to change the articles of association in accordance with option “C”. The new articles of association will be registered with the Swedish Companies Registration Office in connection with the registration of the Rights Issue.
