The share capital shall be increased through a new issue of shares whereby shareholders shall have preferential rights to subscribe for new shares in proportion to the number of shares held on the record date.

The record date for receiving subscription rights is 23 November 2023. The shares in John Mattson are traded, including the right to receive subscription rights, up to and including 21 November 2023. The shares are traded without the right to subscription rights from and including 22 November 2023.

Primarily, allotment shall be made to those who have applied for subscription and subscribed for shares with subscription rights, regardless of whether the subscriber was a shareholder on the record date or not and in case of oversubscription, in proportion to the number of exercised subscription rights and, to the extent this cannot be done, by drawing lots.

This resolution on subsequent approval of the Board of Directors' resolution on a new issue of shares is conditional upon the general meeting also having resolved to amend the articles of association in accordance with item 7.

Resolution to authorise the CEO to decide on adjustment of the resolutions (item 9)

The Board of Directors proposes that the EGM authorises the CEO, or the person otherwise appointed by the CEO, to make minor adjustments and clarifications to the resolutions adopted at the meeting to the extent necessary for the registration and execution of the resolutions.
