Outcome in the Rights Issue
The subscription period in the Rights Issue ended on 22 January 2026. The final outcome shows that 333,868,547 shares, corresponding to approximately 62.1 percent of the Rights Issue, were subscribed for with the support of subscription rights. 10,263,260 shares, corresponding to approximately 1.9 percent of the Rights Issue, were subscribed for without the support of subscription rights. The remaining 193,911,648 shares, corresponding to approximately 36.0 percent of the Rights Issue, were subscribed for by the external investors and existing shareholders who had provided guarantee undertakings, of which approximately 27.9 percent were subscribed for by Arwidsro Investment AB within the top guarantee. The subscription price in the Rights Issue was SEK 0.10 per share, and the Company will receive approximately SEK 53.8 million before issue costs of approximately SEK 5.1 million, of which commission for guarantee undertakings amounts to approximately SEK 3.1 million (provided that all guarantors choose to receive guarantee compensation in cash).

Allotment of shares subscribed for without preferential rights
Allotment of shares subscribed for without preferential rights (i.e., without the support of subscription rights) in the Rights Issue is carried out in accordance with the principles set out in the information document which has been prepared in connection with the Rights Issue and published by the Company on 2 January 2026. Notification of allotment of shares subscribed for without the support of subscription rights will be sent through a settlement note to those who have been allotted such shares, and such shares must be paid in cash according to the instructions on the settlement note. Shareholders registered with a nominee will be notified of allotment in accordance with their respective nominee's procedures.

Guarantee commission
In connection with the Rights Issue, the Company received a guarantee undertaking of SEK 15 million from the Company's existing shareholder Arwidsro Investment AB through a so-called top guarantee. In addition, the Company received guarantee undertakings of SEK 24.0 million from an existing shareholder and a number of external investors through so-called bottom guarantees.

The commission for Arwidsro Investment AB’s guarantee undertaking amounts to 17 percent of the guaranteed amount in the form of newly issued shares in the Company. The other guarantors have the option to choose between a guarantee commission of 15 percent of the guaranteed amount in the form of newly issued shares or 13 percent of the guaranteed amount in cash. The subscription price for shares issued to the guarantors shall amount to SEK 0.10 per share, which corresponds to the subscription price per share in the Rights Issue. The guarantee commission and subscription price have been determined through arm’s length negotiations between the Company and the parties that have provided guarantee undertakings in connection with the entry into the guarantee agreements prior to the Board of Directors’ resolution to carry out the Rights Issue, which was made in consultation with the Company’s financial advisor Bergs Securities. The Board of Directors therefore considers that the terms have been determined in such a way as to ensure market fairness and that they reflect prevailing market conditions.

A resolution to issue new shares to the guarantors (the “Compensation Issue”) will be made by the Company’s Board of Directors based on the authorisation from the Extraordinary General Meeting on 22 December 2025. Information regarding a resolution to issue shares to the guarantors, including whether the guarantors who have provided bottom guarantees have chosen to receive commission in cash or in the form of shares, will be announced through a press release.

Number of shares, share capital and dilution
Through the Rights Issue, the number of shares in Vivesto will increase by 538,043,455 shares, from 538,043,455 shares to 1,076,086,910 shares. The share capital will increase by SEK 53,804,345.5, from SEK 53,804,345.5 to SEK 107,608,691, corresponding to a dilutive effect of 50 percent for shareholders who have chosen not to participate in the Rights Issue.

The Compensation Issue will, assuming that all guarantors choose to receive guarantee commission in the form of shares, result in the Company's share capital increasing by a further SEK 6,152,969.6 through a new issue of 61,529,696 shares, corresponding to a dilutive effect of approximately 5.4 percent (calculated based on the number of outstanding shares in the Company after the Rights Issue).

The last day of trading in paid subscribed shares (BTA) on Nasdaq Stockholm is expected to be on 6 February 2026. The new shares are expected to be admitted to trading on Nasdaq Stockholm around 12 February 2026.
