Resolution to implement incentive program 2026/2032
The AGM resolved, in accordance with the Board of Directors' proposal, that the Company shall implement an incentive program through issuance of warrants to senior executives in the company group and/or to ExpreS2ion Biotechnologies ApS (the "Subsidiary") with subsequent transfer to senior executives in the company group (the "Incentive Program 2026/2032").

As a result of Incentive Program 2026/2032, the Company will issue a maximum of 1,187,449 warrants, which may result in a maximum increase of the Company's share capital of approximately SEK 1,899,918.40. Upon full exercise of all warrants, 1,187,449 new shares can be issued, which corresponds to a dilution of approximately 4.76 percent of the total number of shares and votes in the Company.

The warrants shall be subscribed for by senior executives in the company group and/or the Subsidiary, with the right and obligation for the Subsidiary to, at one or several occasions, transfer the warrants to senior executives who are or will become employed by the company group, at a price equal to the fair market value of the warrant or at no consideration (subject to being tax neutral for the company group) and otherwise on the same terms as in the issuance. The Subsidiary has the right to subscribe for warrants without consideration and the senior executives in the company group have the right to subscribe for or acquire the warrants at a price equal to the warrant's market value, which shall be calculated according to the Black & Scholes valuation model, or at no consideration (subject to being tax neutral for the company group).

Each warrant entitles to subscription of one (1) new share in the Company during the period from and including 3 July 2027 until and including 2 July 2032. The Incentive Program 2026/2032 is a six-year program with a vesting period of the first three years, whereby one-third of the warrants vest each year. The warrants may be exercised during annual exercise windows with successively higher subscription prices based on the volume weighted average price at Nasdaq First North Growth Market during ten trading days up to and including the date of the AGM.

Authorisation for the Board of Directors to issue shares, convertibles and/or warrants
The AGM resolved, in accordance with the Board of Directors’ proposal, to authorise the Board of Directors during the period up until the next Annual General Meeting, on one or more occasions, to resolve to issue shares, convertibles and/or warrants, with deviation from the shareholders' preferential rights, corresponding to not more than 30 percent of the share capital of the Company after completed issuances based on the number of shares at the time of the Annual General Meeting, to be paid in cash, in kind and/or by way of set-off.

The purpose for the Board of Directors to resolve on issuances with deviation from the shareholders' preferential rights in accordance with the above is primarily for the purpose of broadening the shareholder base, raising new capital to increase flexibility of the Company or in connection with acquisitions.

The AGM further resolved, in accordance with the Board of Directors’ proposal, to authorise the Board of Directors to, on one or more occasions until the next Annual General Meeting, without deviating from the shareholders' preferential rights, against payment in cash, in kind and/or by way of set-off, resolve on a new issue of shares, convertibles and/or warrants.
