Reference is made to the stock exchange announcement by Hofseth Biocare ASA ("HBC" or the "Company") on 27 October 2025 regarding completion of a private placement (the "Private Placement") of new shares in the Company, and to the stock exchange announcement on 27 October 2025 regarding key information for a subsequent offering of up to 16,666,666 new Ordinary Shares in the Company (the "Offer Shares"), each at the same subscription price per Offer Share as the subscription price in the Private Placement (the "Subsequent Offering").

The Company's Board of Directors has now resolved to proceed with the Subsequent Offering, which may raise total gross proceeds of up to approximately NOK 30 million. The shareholders in the Company as of 24 October 2025 (the "Existing Shareholders"), as registered in the VPS on 28 October 2025 (the "Record Date"), except (i) shareholders who were offered to apply for Offer Shares in the Private Placement, and (ii) shareholders who are resident in a jurisdiction where such offering would be unlawful or would (in jurisdictions other than Norway) require any prospectus, filing, registration or similar action (the "Eligible Shareholders"). If not all Offer Shares are subscribed and allocated (including through over-subscription) following the subscription period for the Subsequent Offering, any remaining Offer Shares may be subscribed for by investors in the Private Placement or other investors that the Board deems to be of strategic importance for the Company ("Secondary Subscribers"), with allocation at the discretion of the Board. Over-subscription will be permitted. Subscription without Subscription Rights (as defined below), other than for Secondary Subscribers, will not be permitted.

Each Eligible Shareholder will be granted 0.1134 non-transferable subscription rights (the "Subscription Rights") for each existing share in the Company registered as held by the Eligible Shareholder as of the Record Date, rounded down to the nearest whole Subscription Right. Each Subscription Right will give the right to subscribe for, and be allocated, one (1) Offer Share.

The subscription period for the Subsequent Offering will commence on 10 November 2025 at 09:00 (CET) and will end on 20 November 2025 at 16:30 (CET) (the "Subscription Period").

The Subscription Rights must be used to subscribe for Offer Shares prior to the expiry of the Subscription Period on 20 November 2025 at 16:30 (CET). Subscription Rights that are not used to subscribe for Offer Shares before the expiry of the Subscription Period will have no value and will lapse without compensation to the holder.

The terms and conditions for the Subsequent Offering will be set out in a national prospectus be published by the Company in accordance with the rules in the Norwegian Securities Trading Act chapter 7 (the "Prospectus"). The Prospectus will be registered with the Norwegian Register of Business Enterprises and be made available at the websites of the Company (), prior to the start of the Subscription Period. The Prospectus is a national prospectus (Nw: nasjonalt prospekt) and neither the Norwegian Financial Supervisory Authority nor any other public authority has carried out any form of review, control or approval of the Prospectus. The due pate for payment for the Offer Shares is expected to be on 26 November 2025. The Offer Shares will, after registration of the share capital registration pertaining to the Subsequent Offering, be delivered to the subscribers and become listed on Euronext Oslo Børs on or about 2 December 2025. The Offer Shares will have equal rights and rank pari passu with the Company's other Ordinary Shares.

Completion of the Subsequent Offering is conditional upon; (i) all necessary corporate resolutions for implementation of the Subsequent Offering being validly passed, including an extraordinary general meeting of the Company (to be held on 20 November 2025) resolving to grant the Board authorization to raise the share capital in connection with the Subsequent Offering, (ii) the minimum number of Offer Shares (i.e. 1 Offer Share) being subscribed, (iii) payment being received for all subscribed Offer Shares, and (iv) due registration of the share capital increase pertaining to the Offer Shares with the Norwegian Register of Business Enterprises.
