Hørsholm, Denmark, 14 April 2026 - On 7 April 2026, the Board of Directors of ExpreS2ion Biotech Holding AB ("ExpreS2ion" or the "Company") resolved, pursuant to the authorization granted by the extraordinary general meeting held on 1 April 2026, to carry out a new issue of units consisting of shares and warrants of series TO 13 ("Units") with preferential rights for the Company's existing shareholders (the "Rights Issue"). The Company will upon full subscription in the Rights Issue receive initial proceeds of approximately SEK 53 million before deduction of transactions costs. The Board of Directors of ExpreS2ion has in connection with the Rights Issue, and prior to the subscription period, which commences on 16 April 2026, prepared a prospectus which today has been approved by the Swedish Financial Supervisory Authority (Sw. Finansinspektionen) (the "SFSA"). The prospectus has been published on the Company's website and is available in Swedish and English.
Bent Frandsen, ExpreS2ion CEO comments:
"This Rights Issue supports the completion of our ongoing Phase I programme for ES2B-C001, where we have already reported encouraging and durable anti-HER2 responses. The next phase of the study is focused on establishing safety and maximum tolerated dose, with the potential to generate further immunogenicity and early efficacy signals, representing an important value inflection point for the Company. At the same time, we will continue to strengthen our platform and manufacturing capabilities and expand our contract research business, while actively pursuing partnering and outlicensing opportunities. We are encouraged by the continued support from existing shareholders and new investors, which underpins confidence in our strategy."

The Rights Issue in brief
- The Board of Directors of ExpreS2ion, on 7 April 2026, pursuant to the authorization granted by the extraordinary general meeting held on 1 April 2026, resolved on a rights issue of units of approximately SEK 53 million, before deduction of transaction costs.
- The net proceeds from the Rights Issue are primarily intended to be used to complete Phase 1 lead cancer active immunotherapy program aimed for advanced breast cancer patients, support business development activities, strengthen shared R&D and manufacturing capabilities, investment in internal development, CMC-compatibility, grow the contract research business, increase service revenues and margins and co-finance grant projects.
- The subscription price is set to SEK 1.60 per unit, corresponding to SEK 1.60 per share. The warrants of series TO 13 are issued free of charge. The subscription price corresponds to a TERP discount of approximately 20 percent on the volume-weighted average price of the Company's share on Nasdaq First North Growth Market during the measurement period that commenced on 24 March 2026 and ended on 6 April 2026.
- All existing shareholders receive forty-seven (47) unit rights for each share held on the record date on 14 April 2026. Five (5) unit rights entitle the holder to subscribe for one (1) unit. One (1) unit consists of one (1) new share and one (1) warrant of series TO 13.
- The subscription period in the Rights Issue commences on 16 April 2026 and ends on 30 April 2026. The last day of trading in the Company's shares with the right to receive unit rights was 10 April 2026.
- The Company has received subscription commitments from members of the Company's board of directors and management, including CEO Bent U. Frandsen, totalling approximately SEK 0.7 million, corresponding to approximately 1.3 percent of the Rights Issue, and guarantee commitments from external investors totalling SEK 31.1 million, corresponding to approximately 58.6 percent of the Rights Issue. In total, the Rights Issue is thus covered by subscription commitments and guarantee commitments of up to approximately SEK 32 million, corresponding to approximately 60 percent of the Rights Issue.
- One (1) warrant of series TO 13 entitles the holder to subscribe for one (1) new share in the Company against cash payment amounting to 70 percent of the volume-weighted average price of the Company's share on Nasdaq First North Growth Market during the period from and including 20 August 2026 up to and including 2 September 2026, but not less than the quota value of the shares (SEK 1.6 following the registration of the Rights Issue and the share capital reduction as resolved by the extraordinary general meeting 1 April 2026).
- If the Rights Issue is fully subscribed, all warrants of series TO 13 are exercised for subscription of shares and the subscription price amounts to the share's quota value (SEK 1.6 following the registration of the Rights Issue and the share capital reduction as resolved by the extraordinary general meeting 1 April 2026), the Company will receive additional proceeds of approximately SEK 53 million before issue costs, which are estimated to amount to approximately SEK 2 million. If the subscription price under the same conditions amounts to between SEK 2.0 and SEK 3.0, the Company will receive additional proceeds of between approximately SEK 66 and 100 million before issue costs, which are estimated to amount to between approximately SEK 3 - 4 million.
