Background and Rationale
Alzinova is a Swedish biopharmaceutical company in clinical development phase with a focus on the treatment of Alzheimer's disease. The Company has initiated the operational start-up phase for a global Phase 2 clinical study of ALZ-101, an oligomer-specific vaccine candidate being developed to slow the progression of Alzheimer’s disease. The study builds on the results of the company’s completed Phase 1b study.

Data from the Phase 1b clinical study show that ALZ-101 has a favorable safety and tolerability profile during the 84-week study period. The vaccination elicited a robust, long-lasting and recurrent immune response in more than 95 percent of patients, with 31 out of 32 patients generating the desired immune response. In addition, exploratory analyses of cognitive and functional parameters showed a positive trend in treated patients.

In addition, ALZ-101 has received Investigational New Drug (IND) approval and Fast Track designation from the U.S. Food and Drug Administration (FDA). These regulatory advances represent an external validation of the program's potential and enable a more efficient development process.

In parallel with the development of ALZ-101, Alzinova is also developing ALZ-201, an oligomer-specific monoclonal antibody that can be used as a stand-alone disease-modifying treatment or as a complement to ALZ-101. The Company is also in dialogue with international pharmaceutical companies regarding potential partnerships for the continued development and commercialization of ALZ-101. In addition, Alzinova has entered into a letter of intent with Fujirebio regarding the evaluation of a potential collaboration on the development and commercialization of a blood-based diagnostic test for Alzheimer's disease based on the Company's proprietary technology.

Upon full subscription in the Rights Issue, the Company will receive issue proceeds of approximately SEK 51 million, before issue costs. The issue costs are estimated to amount to approximately SEK 8.7 million, of which approximately SEK 4.8 million relates to compensation for underwriting commitments, provided that the underwriter chooses cash compensation. The Company intends to dispose of the net proceeds from the Rights Issue for the following purposes, in order of priority:

• The Phase 2 study of ALZ-101, including patient recruitment and execution of the study, approximately 60 percent.
• CMC activities related to the Phase 2 study, including manufacturing, process development and quality control, approximately 20 percent.
• Working capital for operating activities, approximately 20 percent.

Through the Rights Issue, warrants of series TO5 are issued, free of charge, which, if fully exercised, can provide the Company with an additional maximum of approximately SEK 81 million. Warrants of series TO5 may be exercised for subscription of new shares during the period from and including January 4, 2027, up to and including January 18, 2027. The subscription price for exercise of warrants of series TO5 amounts to SEK 0.50. The proceeds from exercised warrants of series TO5 are intended to be used for:

• The Phase 2 study of ALZ-101, including patient recruitment and execution of the study, approximately 70 percent.
• CMC activities related to the Phase 2 study and IP activities, approximately 8 percent.
• Working capital for operating activities, approximately 22 percent.

Through the Rights Issue, warrants of series TO6 are also issued, free of charge, which, if fully exercised, may provide the Company with an additional maximum of approximately SEK 122 million. Warrants of series TO6 may be exercised for subscription of new shares during the period from and including October 7, 2027, up to and including October 21, 2027. The subscription price upon exercise of warrants of series TO6 amounts to seventy (70) percent of the volume-weighted average price of the Company's share during the period from and including September 23, 2027, up to and including October 6, 2027, however, not less than the quota value of the share and not more than SEK 1.00.

Subscription commitments and underwriting commitments

The Rights Issue is covered to approximately 1.0 percent by subscription commitments, corresponding to approximately SEK 0.5 million. In addition, Mangold Fondkommission AB[1] has entered into an underwriting commitment of a total of approximately 78.3 percent of the Rights Issue, corresponding to approximately SEK 40 million. Thus, the Rights Issue is covered to 79.3 percent by subscription commitments and underwriting commitments. Subscription commitments entered into and underwriting commitments are not secured through bank guarantees, pledges or similar arrangements.

For the underwriting commitment, underwriting compensation of either twelve (12) percent of the underwritten amount is paid in cash or fifteen (15) percent of the underwritten amount in the form of units, or a combination thereof. The Board of Directors considers it beneficial for the Company to offer compensation to the underwriter in the form of units as it has a positive effect on the Company's liquidity. Underwriting compensation in units is intended to be paid through a directed issue of units to the underwriter to the extent that the underwriter chooses to receive the underwriting compensation in units, provided that and to the extent that such issue is within the limits in force at the time of the issue decision in the Company's Articles of Association. To the extent that underwriting compensation cannot be paid in the form of units due to the limits of the Articles of Association, such part of the underwriting compensation shall instead be paid in cash and calculated according to the level of compensation that applies to cash underwriting compensation. In the event that the underwriter chooses remuneration in the form of units in the Company, the subscription price per unit shall correspond to the subscription price in the Rights Issue, i.e. SEK 1.26 per unit, corresponding to SEK 0.42 per share. No compensation will be paid for subscription commitments.

In the event that the underwriter is allotted units in the Rights Issue subscribed for without the exercise of preferential rights, the amount to which such subscription relates shall be deducted from the underwriting commitment. Units subscribed for by the underwriter with the exercise of preferential rights, based on unit rights received in the Rights Issue, are not covered by such settlement.

Complete terms and conditions for the Rights Issue as well as other information about the Company will be set out in the Memorandum that will be published by the Company before the start of the subscription period.
