PROPOSED RESOLUTIONS

Item 7 – Resolution to amend the articles of association

In order to enable the reduction of the share capital pursuant to item 8 and the rights issue resolved upon by the Board of Directors on 30 October 2026, the Board of Directors proposes that the Extraordinary General Meeting resolve to amend the limits for the share capital and the number of shares in the articles of association as follows. The other provisions of the articles of association remain unchanged. As of the date of this notice, there are a total of 99,577,003 shares in the Company and the share capital amounts to SEK 18,720,476.564.

The resolution is conditional upon the Extraordinary General Meeting also resolving in accordance with the Board of Directors’ proposals under items 8 and 9. Should the share capital or the number of shares in the Company, following registration of the reduction of the share capital and the rights issue, fall below the proposed limits in the articles of association, the limits shall be reduced to the extent required to enable registration.

The CEO, or such person as the Board of Directors appoints, shall be entitled to make such minor adjustments as may be required in connection with the registration of the resolution with the Swedish Companies Registration Office and Euroclear Nordics AB.

For a valid resolution, the proposal must be supported by shareholders representing at least two-thirds (2/3) of both the votes cast at the meeting and the shares represented at the meeting.

Item 8 – Resolution to reduce the share capital without cancellation of shares to cover losses

The Board of Directors proposes that the Extraordinary General Meeting resolve to reduce the Company’s share capital by SEK 14,239,511.429 to cover losses. The reduction shall be carried out without cancellation of shares by changing the quota value of each share from approximately SEK 0.188 to SEK 0.045. The number of shares is not affected by the reduction of the share capital.

The purpose of the proposal is to provide the Company with a more appropriate quota value and to enable the Company to carry out the rights issue pursuant to item 9 of the agenda at the subscription price stated therein. The reduction shall be used to cover losses that cannot be covered by unrestricted equity according to the most recently adopted balance sheet. Following completion of the reduction in accordance with the proposal, the Company’s share capital will amount to SEK 4 480 965.135, divided into 99,577,003 shares (prior to the rights issue), each share having a quota value of SEK 0.045.

As the reduction is made to cover losses, no authorisation from the Swedish Companies Registration Office or a general court is required to implement the resolution. The reduction of the share capital shall be registered with the Swedish Companies Registration Office at the same time as the amendment to the articles of association pursuant to item 7 and the registration of the shares in the rights issue pursuant to item 9.
The CEO, or such person as the Board of Directors appoints, shall be entitled to make such minor adjustments as may be required in connection with the registration of the resolution with the Swedish Companies Registration Office and Euroclear Nordics AB.

For a valid resolution under this item, the resolution must be supported by shareholders holding at least two-thirds of both the votes cast and the shares represented at the meeting.

The resolution to reduce the share capital is conditional upon the Extraordinary General Meeting also resolving to amend the articles of association pursuant to item 7 and approving the rights issue pursuant to item 9, and upon the registration of those resolutions with the Swedish Companies Registration Office.

Item 9 – Resolution to approve the Board of Directors’ resolution dated 30 October 2026 on an issue of units with preferential rights for existing shareholders

On 30 October 2026, subject to approval by the Extraordinary General Meeting, the Board of Directors resolved on an issue of no more than 99,577,003 units consisting of shares and warrants of series TO6, with preferential rights for existing shareholders, corresponding to issue proceeds of no more than approximately SEK 54.8 million before issue costs (the “Rights Issue”). The Board of Directors proposes that the Extraordinary General Meeting approve the Board of Directors’ resolution on the Rights Issue in accordance with the terms and conditions set out below.

1. The new shares and warrants shall be issued together in units. Each unit shall consist of five (5) shares and five (5) warrants of series TO6.
2. The Company’s share capital may be increased by no more than SEK 22,404,825.675 through the issue of no more than 497,885,015 shares. No more than 497,885,015 warrants of series TO6 shall be issued, entailing an increase in the share capital, upon full exercise of the warrants, of no more than SEK 22,404,825.675.
3. Shareholders registered in the share register maintained by Euroclear Nordics AB for the Company on the record date of 4 December 2026 shall receive one (1) unit right for each one (1) share held. One (1) unit right is required to subscribe for one (1) unit.
4. If not all units are subscribed for by exercise of unit rights, the Board of Directors shall, within the maximum amount of the Rights Issue, resolve on allotment in accordance with the allotment principles set out below:
   1. Firstly, allotment shall be made to those who have subscribed for units by exercise of unit rights, irrespective of whether the subscriber was a shareholder on the record date or not, and, in the event of oversubscription, in proportion to the number of unit rights exercised by each person to subscribe for units and, to the extent this is not possible, by drawing lots.
   2. Secondly, allotment shall be made to others who have subscribed for units without exercise of unit rights and, if they cannot receive full allotment, in proportion to the number of units each person has applied to subscribe for and, to the extent this is not possible, by drawing lots.
   3. Finally, any remaining units shall be allotted to the issue guarantors that have entered into guarantee commitments in proportion to the size of their respective guarantee commitments and, to the extent this is not possible, by drawing lots.
5. Subscription for units shall take place during the period from and including 8 December 2026 up to and including 22 December 2026. The Board of Directors shall be entitled to extend the subscription period.
6. The subscription price shall be SEK 0.55 per unit, corresponding to SEK 0.11 per share. The warrants shall be issued free of charge. The subscription price corresponds to a discount of approximately 23.8 per cent compared to the theoretical ex-rights price (TERP), assuming full subscription of the new share issue and calculated on the basis of the volume-weighted average price (VWAP) of the share during the period from and including 26 October 2026 up to and including 30 October 2026. Any share premium shall be added to the free share premium fund.
7. Subscription may only be made for units, not for shares and warrants separately. Allotment may only be made in units. Following completion of the Rights Issue, however, the shares and warrants will be separated.
8. Payment for units shall be made in cash. Payment for units subscribed for with preferential rights shall be made simultaneously with subscription during the period from and including 8 December 2026 up to and including 22 December 2026. Payment for units subscribed for without preferential rights shall be made no later than three (3) banking days after an allotment notice has been sent to the subscriber. The Board of Directors shall be entitled to extend the payment period.
9. Each warrant of series TO6 shall entitle the holder to subscribe for one (1) share at a subscription price of SEK 0.12.
10. Subscription for new shares through exercise of warrants of series TO6 may take place during the period from and including 31 May 2027 up to and including 14 June 2027. Any share premium upon subscription for new shares through exercise of the warrants shall be added to the free share premium fund. The warrants are subject to further terms and conditions, including customary recalculation terms.
11. The new shares shall be entitled to receive dividends for the first time on the first record date for dividends after the shares have been registered with the Swedish Companies Registration Office and entered in the share register maintained by Euroclear Nordics AB. The new shares resulting from exercise of the warrants shall be entitled to receive dividends for the first time on the first record date for dividends after the shares have been registered with the Swedish Companies Registration Office and entered in the share register maintained by Euroclear Nordics AB.

The Board of Directors, or any person appointed by the Board of Directors, shall be entitled to make such minor adjustments to the above resolution as may prove necessary in connection with registration with the Swedish Companies Registration Office and Euroclear Nordics AB.

A resolution pursuant to this item is conditional upon the Extraordinary General Meeting also resolving on an amendment to the articles of association pursuant to item 7 and a reduction of the share capital pursuant to item 8 on the agenda, and upon such resolutions being registered with the Swedish Companies Registration Office.

In connection with the Rights Issue, the Company intends to prepare an EU Follow-on Prospectus (the “Prospectus”). The Prospectus is expected to be published on the Company’s website around 3 December 2026, before the beginning of the subscription period.

Item 10 – Resolution to authorise the Board of Directors to make minor adjustments to the resolutions passed at the general meeting

The Board of Directors proposes that the Extraordinary General Meeting authorise the Board of Directors, the CEO, or any person otherwise appointed by the Board of Directors or the CEO, to make such minor adjustments and clarifications to the resolutions passed at the general meeting to the extent necessary for registration of the resolutions with the Swedish Companies Registration Office and Euroclear Nordics AB.
