NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART DIRECTLY OR INDIRECTLY, IN AUSTRALIA, CANADA, JAPAN OR THE UNITED STATES OR ANOTHER JURISDICTION IN WHICH THE RELEASE, PUBLICATION OR DISTRIBUTION WOULD BE UNLAWFUL. THIS ANNOUNCEMENT DOES NOT CONSTITUTE AN OFFER OF ANY OF THE SECURITIES DESCRIBED HEREIN.

Reference is made to previous announcements by Hofseth BioCare ASA (the "Company") regarding a subsequent offering with gross proceeds of up to approx. NOK 30,000,000 through issuance of up to 16,666,666 new ordinary shares (the "Offer Shares") at a subscription price of NOK 1.80 per share (the "Subsequent Offering").

The Subsequent Offering was directed towards the shareholders of the Company as of 24 October 2025 (as registered in the VPS on 28 October 2025), except: (i) shareholders who were offered or allocated shares in the private placement announced as placed on 27 October 2025 (the "Private Placement"), and (ii) shareholders who are resident in a jurisdiction where such offering would be unlawful or, for jurisdictions other than Norway, would require any prospectus, filing, registration or similar action (the "Eligible Shareholders"). Provided that the Eligible Shareholders did not subscribe for all available Offer Shares, any remaining Offer Shares may be subscribed for by investors in the Private Placement or other investors that the Company's board of directors (the "Board") deems to be of strategic importance for the Company ("Secondary Subscribers"), with allocation to such Secondary Subscribers at the discretion of the Board.

The application period in the Subsequent Offering ended on 20 November 2025 at 16.30 CET. At the end of the application period, the Company had received applications for 1,215,560 Offer Shares.

The Board has now allocated shares in the Subsequent Offering, which implies that the Company shall issue 1,215,560 Offer Shares. The Board has allocated 1,215,560 Offer Shares, of which all to Eligible Shareholders. Allocation letters, detailing the number of Offer Shares allocated and the corresponding subscription amount to be paid, will be distributed to the subscribers shortly.

In order to issue Offer Shares to the subscribers, a general meeting of the Company (held on 20 November 2025) granted the Board an authorization to increase the Company's share capital with up to NOK 166,666.66. This authorization has not yet been registered with the Norwegian Register of Business Enterprises, and the Board will therefore re-convene at a later time to resolve the share capital increase in connection with the Subsequent Offering.

Completion of the Subsequent Offering is subject to; (i) the Board authorization to raise the share capital in connection with the Subsequent Offering being validly registered in the Norwegian Register of Business Enterprises and the Board validly resolving to increase the share capital in connection with the Subsequent Offering, (ii) payment being received for all subscribed Offer Shares, and (iii) due registration of the share capital increase pertaining to the Subsequent Offering with the Norwegian Register of Business Enterprises.

Advokatfirmaet CLP DA is acting as legal advisor to the Company.
