Background and rationale in summary
Biosergen AB is a Swedish clinical stage pharmaceutical company. The company's drug candidate BSG005 is a potentially groundbreaking antifungal, which has demonstrated significant safety and potency advantages compared to similar medications. The drug is based on an anti-fungal molecule from the group of polyene macrolides and is currently entering the first in-patient safety and efficacy study, with topline data expected in Q3 2024. To continue this research and product development and to fund the clinical development of the drug, the Company has recognized a need to implement a capital raise. The Company has resolved on the Rights Issue to give all shareholders the right to participate in the issue and fund the treatment of this overlooked emerging disaster of invasive fungal infections.

The proceeds of the Rights Issue and the warrants of series TO3 shall primarily be used for:

• Completion of the first in-patient safety and efficacy study for BSG005
• CMC investments to cover the phase 2 and 3 studies (both studies will be managed and financed by Biosergen's partner Alkem Laboratories Ltd)
• Offsetting the Bridge loan

Terms for the Rights Issue
The Board of Directors of Biosergen has today, subject to approval from a subsequent extraordinary general meeting scheduled to be held on March 1, 2024, resolved on the Rights Issue in accordance with the following main terms:

• All existing shareholders will receive one (1) unit right for each one (1) share owned on the record date, March 5, 2024, and three (3) unit rights give the right to subscribe for one (1) unit. One (1) unit consists of eight (8) newly issued shares and eight (8) warrants of series TO3.

Subscription commitments, underwriting commitments, lock-up and potential compensation issue
The Rights Issue is covered to approximately 65 percent through subscription commitment and underwriting commitments. The subscription commitments and underwriting commitments are not secured through bank guarantees, pledge, or similar arrangements. A subscription commitment of approximately SEK 13.5 million has been provided by Östersjöstiftelsen, the largest shareholder of the Company. The underwriting commitments have been provided by existing shareholders and external investors. For the underwriting commitments, underwriting compensation will be paid either in cash or in the form of newly issued units. In case of payment in cash, the underwriting compensation will correspond to twelve (12) percent of the underwritten amount. In case of payment in the form of newly issued units, the underwriting compensation will correspond to fifteen (15) percent of the underwritten amount, with a subscription price corresponding to the subscription price per unit in the Rights Issue, which the Board of Directors deems to be market terms. No compensation is paid for the subscription commitment.

Some underwriters have provided underwriting commitments which could result in an ownership that exceed ten percent of the votes in the Company if the Rights Issue is only subscribed up to the level covered by subscription and underwriting commitments. To the extent the underwriters' fulfilment of such commitment entails that the investment must be approved by the Inspectorate of Strategic Products (Sw. Inspektionen för strategiska produkter) in accordance with the Swedish Screening of Foreign Direct Investments Act (Sw. lagen (2023:560) om granskning av utländska direktinvesteringar), such part of the commitment is conditional upon notification that the application of the transaction is left without action or that approval has been obtained from the Inspectorate of Strategic Products.
