PLEASE SEE THE SECTION “IMPORTANT INFORMATION” AT THE END OF THIS PRESS RELEASE.

The Board of Directors of Vivesto AB (“Vivesto” or the “Company”) has today, based on the authorisation from the Extraordinary General Meeting held on 22 December 2025, resolved on a directed new issue of 31,050,000 shares to certain guarantors in the rights issue of shares resolved upon by the Board of Directors on 20 November 2025 (the “Rights Issue“), in accordance with the guarantee agreements previously communicated (the “Compensation Issue“). The subscription price in the Compensation Issue is SEK 0.10 per share, and payment is made by offsetting the guarantors’ claims on the Company.

In connection with the Rights Issue, the Company received guarantee undertakings from the existing shareholder Arwidsro Investment AB (“Arwidsro Investment”) through a so-called top guarantee, as well as from an additional existing shareholder and a number of external investors through so-called bottom guarantees. As communicated in connection with the announcement of the Rights Issue, the guarantors are, according to the guarantee agreements entered into, entitled to commission, whereby commission for the bottom guarantee undertakings is paid with 15 percent of the guaranteed amount in the form of newly issued shares in the Company, or alternatively 13 percent of the guaranteed amount in the form of cash commission. For the top guarantee undertaking provided by Arwidsro Investment, commission is paid with 17 percent of the guaranteed amount, only in the form of newly issued shares in the Company.

In addition to Arwidsro Investment, a number of guarantors have chosen to receive guarantee commission in the form of shares, whereas the others will receive cash guarantee commission. Accordingly, the Board of Directors of Vivesto has today, based on the authorisation from the Extraordinary General Meeting held on 22 December 2025, resolved on the Compensation Issue, comprising 31,050,000 shares to Arwidsro Investment and the bottom guarantors who have chosen to receive guarantee commission in the form of shares. The cash portion of the guarantee commission paid to bottom guarantors who have chosen cash commission amounts to approximately SEK 2.6 million.

The reason for the deviation from the shareholders’ preferential rights is to fulfil the Company’s obligations to the guarantors, as they under the guarantee agreements entered into are entitled to set off their claims against the Company arising from guarantee undertakings provided in connection with the Rights Issue. In addition, the Board of Directors considers that it is beneficial to the Company’s financial position and in the interest of the shareholders to settle the guarantee commission in the form of shares instead of cash payment, as it preserves cash resources, thus strengthening the Company’s working capital.

Payment in the Compensation Issue shall be made by set-off of claims against the Company, which consists of these guarantors’ entitlement to guarantee commission. The subscription price in the Compensation Issue amounts to SEK 0.10 per share, which corresponds to the subscription price per share in the Rights Issue. The guarantee commission and the subscription price were 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.

Through the Compensation Issue, the Company’s share capital will increase by SEK 3,105,000, from SEK 107,608,691 to SEK 110,713,691, through a new issue of 31,050,000 shares, which entails that the total number of shares in the Company will increase from 1,076,086,910 to 1,107,136,910, corresponding to a dilutive effect of approximately 2.8 percent of the total number of shares and votes in the Company. The above figures are calculated based on the number of outstanding shares in the Company following registration with the Swedish Companies Registration Office of the Rights Issue.

Advisors
In connection with the Rights Issue, Vivesto has engaged Bergs Securities as financial advisor and Sole Bookrunner. TM & Partners is acting as legal advisor to the Company.
