COPENHAGEN, Denmark, May 7, 2026 - Evaxion A/S (NASDAQ: EVAX) (“Evaxion”), a clinical-stage TechBio company developing novel vaccines with its pioneering AI-Immunology™ platform, provides business update and announces first quarter 2026 financial results.

Business highlights (since last quarterly update)
Evaxion has had a good start to the year executing on our plans and achieving our first milestone for 2026 as expected. Highlights include:

• New data demonstrating an 86% vaccine target recognition by AI-Immunology™ in personalized cancer vaccine EVX-01 is a further scientific validation of the platform’s precision in driving immune response. This marked our first milestone for the year
• Another new set of data confirming the platform’s unique scalability in glioblastoma
• Successful completion of the one-year extension of our phase 2 trial with EVX-01 paving the way for presentation of three-year clinical data in the second half of 2026
• Presentation of potentially superior design concepts for new polio vaccines stemming from our collaboration with The Gates Foundation
• Organizational optimization for strategy execution with the promotion of Birgitte Rønø to the dual role of Chief Scientific and Chief Operating Officer and the election of Jens Bitsch-Nørhave to the Board of Directors
• Cash runway unchanged with cash at hand to fund operations into the second half of 2027

“We maintain strong operational momentum as we continue our work to consolidate our position as a leader in AI-based target discovery, drug design and development. The validation of AI-Immunology™ continues to be reinforced with a host of new promising data presented, which forms a solid foundation for our ongoing business development efforts. We are pleased to have further strengthened our organization to focus on these with the promotion of Birgitte Rønø and inclusion of Jens Bitsch-Nørhave as a formal member of our Board of Directors,” says Helen Tayton-Martin, CEO of Evaxion.

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

EVX-01 is our most advanced asset. Developed with AI-Immunology™, it is a personalized cancer vaccine designed to target multiple neoantigens; cancer unique proteins arising from mutations. We completed the initially planned two-years of treatment in the phase 2 trial with EVX-01 in patients with advanced melanoma (skin cancer) last year with unprecedented results and presented new immunogenicity data from the trial at the American Association for Cancer Research (AACR) Annual Meeting last month.

The data demonstrates that AI-Immunology™ identifies and selects the most therapeutically relevant vaccine targets as 86% of the targets included in EVX-01 trigger a tumor-specific immune response. This is a success rate much higher than what has been reported for other methods.

The record-high vaccine target precision underscores the therapeutic potential of EVX-01 and is also a further validation of AI-Immunology™ as an effective tool for developing potentially transformational treatments in melanoma as well as potentially other cancer indications with high mutational burden. This is of course important for the technology itself, but also very supportive of our ongoing work to enter additional strategic partnerships and business development deals.

At AACR, we also presented new data confirming the scalability of AI-Immunology™ allowing for its application in several diseases. This includes the deadly brain cancer glioblastoma, for which the platform uniquely can identify a novel source of targets to include in therapeutic vaccines, potentially enhancing their efficacy.

The data was generated in collaboration with Duke University School of Medicine and has created significant interest in the field of glioblastoma, an area of high unmet medical need.

We have completed the one-year extension of the phase 2 trial with EVX-01 with the last patient having last physician visit in April. In the third year, patients received EVX-01 as monotherapy, allowing an evaluation of the vaccine’s effect also as stand-alone treatment. Further, the three-year data may provide additional insights into potential enhanced treatment effects and durability of the induced immune response. We expect to present this data in the second half of 2026.

We also maintain a high activity level within our infectious disease programs as showcased by our presentation of new polio vaccine design concepts stemming from our collaboration with The Gates Foundation. These could potentially be superior to currently used vaccines and provide a basis for designing a specific new polio vaccine.

Current polio vaccines are based on inactivated or attenuated versions of the virus. Whilst these vaccines are effective, they each have shortcomings in certain settings. Thus, it has been a long-standing - but so far unreachable - goal to create a novel polio vaccine that combines the strongest aspects of the existing vaccines.

To achieve this, we have deployed AI-Immunology™ to develop novel vaccine design concepts for a next-generation polio vaccine, which may enhance the chances of completing and sustaining polio eradication once and for all.

Business development update
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.

To this end, we were pleased to promote Birgitte Rønø to joint role of Chief Scientific and Chief Operating Officer reflecting optimal internal organization to support partnering activities and internal strategy execution.

Further, we are excited to have welcomed Jens Bitsch-Nørhave to our Board of Directors. With more than 25 years of leadership experience in the biotech and pharmaceutical industry, specializing in corporate strategy, global expansion, and dealmaking, Jens will be a strong contributor to our business development activities.

First quarter 2026 financial results
The financial results for the first quarter 2026 showed a net loss of $3.6 million, compared to $1.6 million first quarter 2025. This is explained by financial income from remeasurement of derivative liability in the first quarter last year, whereas the operating expenses and results were slightly reduced in first quarter 2026.

Research and development (R&D) expenses were $2.3 million for the first quarter 2026, which is a slight increase compared to same period last year, as we progress our pipeline according to plan.

General and administrative (G&A) expenses were $1.5 million for the quarter, compared to $1.7 million in first quarter 2025. The decrease is primarily driven by lower capital market costs.

Financial income of $0.3 million first three months of 2026 compared to $2.4 million same period last year, is due to financial income recorded in 2025 from remeasurement of derivative liability from the January 2025 public offering.

Cash and cash equivalents as of March 31, 2026, were $18.4 million, compared to $23.2 million as of December 31, 2025, and confirms our current cash runway until second half of 2027.

Total equity amounts to $13.2 million as of March 31, 2026, reflecting the net result of the first quarter 2026 when compared to $17.0 million as of December 31, 2025.
