2026 milestones
Based on the strengthening of Evaxion during 2025 we continue the execution of our strategy of creating value from both our platform and R&D pipeline assets through partnerships. This is reflected in our milestones for 2026 covering both the continued expansion of AI-Immunology™ and the progression of our R&D pipeline programs as outlined below.

Leveraging the unique scalability of AI-Immunology™, we will expand the platform to also enable the discovery and development of drug candidates targeting autoimmune diseases (AIDs). This will increase the pool of diseases for which we can potentially discover and develop new treatments.

AIDs are characterized by high unmet medical need and offer significant partnership potential across all stages of drug development. Currently, we are optimizing the indication strategy for development of AI-Immunology™ in the autoimmune space for use in the second half of 2026.

In oncology, we will continue to strengthen the data package for EVX-01, our personalized cancer vaccine in advanced melanoma, with additional biomarker and immunogenicity findings as well as three-year clinical results from the extension of the phase 2 trial. We plan to present both datasets at key medical conferences during the year.

Progressing our cancer vaccine pipeline also includes the preparation for a phase 1 trial with EVX-04, our conserved antigen vaccine in AML. Regulatory filing is expected before the end of the year.

In our infectious disease pipeline, the most significant expected event is the design and preclinical validation of antigens for our Group A Streptococcus vaccine, EVX-B4, with new data anticipated to be presented at a conference in the second half of the year.

Further to our specific 2026 milestones, we maintain our efforts to derive value from partnerships. This includes platform deals focusing on target discovery, candidate, validation and optimization plus pipeline deals focusing on validated assets. We continue to see strong external interest in both areas and are engaged in numerous partnership discussions. 

We maintain strict cost control and are diligently prioritizing and optimizing our cash and resource allocation. For 2026, we expect a cash expenditure similar to 2025, e.g. an operational cash burn of ~$14 million.

Research & Development (R&D) update
Evaxion has a R&D pipeline of innovative vaccine candidates for both cancer and infectious diseases.

The personalized cancer vaccine EVX-01 is our most advanced asset. Developed with AI-Immunology™, it is designed to target multiple neoantigens; cancer unique proteins arising from mutations. We successfully completed the initially planned two-years of treatment in the phase 2 trial with EVX-01 in patients with advanced melanoma (skin cancer) with unprecedented results presented at an oral session at the prestigious ESMO 2025 conference.

Clinical results included an objective response rate of 75%, as 12 out of 16 patients had objective clinical responses, with four patients obtaining a complete response. Additionally, a durable clinical benefit was observed with 92% of patients still responding at two years of follow-up with no relapses.

In the trial, EVX-01 induced an immune response in all patients, with 81% of the targeted neoantigens generating potent, specific T-cell responses. This high immunogenicity rate stands out as highly encouraging compared to historical observations and compares very favorably to what is seen with other neoantigen prediction approaches.

Further immune data, presented at the SITC 2025 conference, showed that in subsets of analyzed patients, clinical responses were accompanied by a rapid and sustained induction of EVX-01-specific T-cells.

While all these data are encouraging and validates the clinical potential of EVX-01, it also provides a wider validation of AI-Immunology™, its predictive capabilities and its ability to find relevant vaccine targets associated with high clinical efficacy.

This validation was further supported both by the licensing of an undisclosed infectious disease program (EVX-B3) by MSD, the collaboration on polio with the Gates Foundation and the Galien Foundation award and serves as an important foundation on the use of AI-Immunology™ for all of our partnering discussions. We received the Galien Foundation Prix Bridges Award for Best medical technology/AI advances in human health for AI-Immunology™, further reinforcing our positioning as a leader in the field of AI-based target discovery.

EVX-04, the AML vaccine added to our pipeline in 2025, is developed through the ability of AI-Immunology™ to identify non-conventional endogenous retrovirus (ERV) tumor antigens from the dark genome. These antigens are selectively expressed in specific tumors but absent in normal tissue, making them highly attractive cancer vaccine targets.

Using sequencing data from AML patients, the AI-Immunology™ platform first identified ERV tumor antigens and then mined these to determine smaller fragments with the potential for immune recognition. From the five million ERV antigen fragments discovered, AI-Immunology™ combined and selected 16 optimal sets of ERV fragments based on their cross-patient relevance and immunogenic potential.

In December 2025, we presented new data for EVX-04 at an oral session at the ASH 2025 meeting, another very prestigious conference. The data demonstrates that all 16 ERV fragments included in EVX-04 elicit a specific immune response and that the vaccine candidate prevents tumor growth in preclinical tumor models. Thus, the data confirms our belief that EVX-04 could significantly improve treatment options for AML patients. It is another example of the unique capabilities of AI-Immunology™ in finding novel targets enabling the design of therapies with transformative potential.

These capabilities are also applied in our EVX-V1 program targeting Cytomegalovirus (CMV). AI-Immunology™ has discovered novel CMV antigens and EVX-V1 is a next-generation, multi-component vaccine program combining these novel AI-discovered antigens with AI-optimized versions of established CMV vaccine antigens. This broader multi-targeted strategy is expected to strengthen the protective potential of the future vaccine.

Data announced in November 2025 demonstrates protective effects of lead antigens in the program. These previously unexplored CMV-antigens induce specific immune responses, inhibit viral infection and reduce cell-to-cell spread in cellular and animal viral infection models. These are significant discoveries since very few protective CMV-antigens have been identified despite decades of intensive research.

Business development update
We are immensely proud to be the first company ever to license an AI-discovered preclinical vaccine candidate to a pharmaceutical company through the agreement on EVX-B3 with MSD. We received $7.5 million in option exercise fee and will be eligible for future payments of up to $592 million.

Subsequently, whilst MSD chose not to exercise its option on our Gonorrhea candidate EVX-B2, we retain full global rights to this exciting program and its strong data package. We are in the process of looking for another potential licensing partner.

We remain active in several parallel partnership discussions based on external interest in both our platform and pipeline as we continue to pursue our strategy of strengthening our platform and building value through multiple partnerships.

Strengthening of financial position and equity
Our financial position and equity were significantly enhanced through an influx of new capital totaling more than $30 million in 2025, including the $7.5 million option exercise fee from MSD. As a result, we significantly extended our cash runway and now hold cash on hand to fund our operations into the second half of 2027.

Our equity was further bolstered by the debt conversion agreement with the EIB, which also has a rolling positive cash effect in the form of lower interest payments.

Further to the extended cash runway, we have also improved our funding options going forward, even if we have no imminent need for new capital. Following the positive development in our market capitalization as a result of MSD’s option exercise, we were able to amend our Form F-3 shelf registration and ATM facility.

This potentially allows for flexible and cost-effective funding on optimal terms for Evaxion and our shareholders until March 2028. If and when funding needs should arise, we will be able to issue up to $45.5 million worth of Evaxion shares if and when market conditions allow during the coming three years.

Full year 2025 financial results
The financial results for the year 2025 showed a net loss of $7.7 million, an improvement of $2.9 million compared to 2024, driven by higher revenue and lower operating expenses.

Throughout 2025, we have delivered and executed according to our financial strategy, resulting in improved equity, lower leverage and extended cash runway.

Revenue for the year 2025 of $7.5 million relates to the MSD option exercise as well as the grant received from the Gates Foundation. With the out-licensing of EVX-B3 to MSD, all future development costs of the program will be carried by MSD, while the deal provides Evaxion with future revenue income potential of up to $592 million through milestone payments.

Research and development (R&D) expenses were $10.0 million for the year 2025, which is according to plan for the year, and slightly lower than the $10.5 million as shown for 2024. The lower R&D costs are mainly related to reduced external services and expenses.

General and administrative expenses were $6.8 million for the full year 2025, compared to $7.6 million in 2024. The decrease is primarily driven by lower capital market transaction costs.

Net financial income of $0.6 million is driven by $2.6 million financial income due to the share price premium from the EIB debt-to-equity conversion finalized in July 2025, and $2.4 million financial expense due to remeasurement of the derivative liability from the January 2025 public offering investor warrants.

Cash and cash equivalents as of December 31, 2025, were $23.2 million, compared to $6.0 million as of December 31, 2024, a significant strengthening achieved through out-licensing deal with MSD, debt-to-equity conversion with EIB, ATM facility and capital market activity.

Total equity amounts to $17.0 million as of December 31, 2025, which is a significant improvement compared to a negative equity of $1.7 million as of December 31, 2024.
