Chikungunya Vaccine, Recombinant (Bavarian Nordic)

COPENHAGEN, Denmark, November 14, 2025 – Bavarian Nordic A/S (OMX: BAVA) announced today its interim financial results for the first nine months of 2025 and business progress for the third quarter of 2025. Revenue for the first nine months increased by 32% to DKK 4,793 million, reflecting a strong performance in both Travel Health and Public Preparedness. Travel Health revenue increased by 23% to DKK 2,327 million compared to the first nine months of 2024, primarily driven by increased demand for rabies and tick-borne encephalitis (TBE) vaccines, and supported by the gradual launch of the chikungunya vaccine, Vimkunya®.Public Preparedness revenue was DKK 2,334 million, exceeding the expected annual base business (DKK 1,500-2,000 million) within the first nine months of the year. Other revenue was DKK 132 million. Other operating income of DKK 810 million has been recognized (net income) from the sale of the Priority Review Voucher. EBITDA before special items was DKK 1,477 million, corresponding to an EBITDA margin of 31%. The full year financial guidance is further refined and remains within the previously guided revenue and EBITDA intervals. In Travel Health, revenue is maintained at approximately DKK 2,750 million, including approximately DKK 75 million from first-year sales of Vimkunya. For Public Preparedness, revenue is narrowed to reflect the low end of the guidance of approximately DKK 3,100 million, all of which has been secured. Other income is maintained at approximately DKK 150 million. Hence, total revenue of approximately DKK 6,000 million and an EBITDA margin before special items of approximately 26% are expected for the full year. This is lower than the margin of 31% realized during the first nine months due to the uneven allocation of revenue across the quarters and back-end-loaded research and development costs as well as sales and distribution costs. When including the net income of DKK 810 million from the sale of the Priority Review Voucher, the total EBITDA margin is expected to be approximately 40%.

Paul Chaplin, President & Chief Executive Officer of Bavarian Nordic said: “Our travel health portfolio has showed continued strength, contributing to our best quarter for this business to date. Driven by higher demand and strong performance by our rabies and TBE vaccines in key markets, but also by our recent launch of Vimkunya chikungunya vaccine and the commercial expansion across markets, we delivered 23% growth over the first nine months. We are on track to meet our financial expectations for 2025, which we are now refining to reflect that we now have full clarity of our Public Preparedness business for the remainder of the year. For next year, we have secured additional orders for this business through our recent framework agreement with HERA, demonstrating a continued and sustainable business. Following the withdrawal of the offer from the consortium of Nordic Capital and Permira after not reaching the threshold required for completion, we acknowledge the decision by the shareholders to continue as an independent company in support of our existing strategy, which we remain fully committed to.” Highlights from the third quarter Following the launch of Vimkunya® chikungunya vaccine in the US, Germany and France during the first half of 2025, the global launch has continued throughout the third quarter where the vaccine also became available in the United Kingdom and Denmark in September. Vimkunya has since also been launched in Sweden, Norway and Finland, Italy and Spain during October.Additional regulatory advances for Vimkunya were made during the third quarter. In July, Health Canada accepted for review the application for licensure of the vaccine, potentially supporting approval in the first half of 2026, and an application was also submitted to the Swiss regulatory authority, Swissmedic, potentially supporting approval in mid-2026.In July, Bavarian Nordic entered a contract valued at over DKK 200 million for the supply of smallpox/mpox vaccines to a European country. The sale of the Priority Review Voucher, granted in connection with the US approval of Vimkunya, was completed in July with net proceeds amounting to DKK 810 million. Events after the reporting date In October, positive topline results were reported from a clinical study of the mpox/smallpox vaccine in a pediatric population. The study met its primary endpoint, demonstrating a comparable safety profile and a non-inferior immune response for MVA-BN in children aged 2-11 years compared to adults. The results will support a filing for label extension with the European Medicines Agency in 2026.In October, Bavarian Nordic donated 110,000 doses of the mpox vaccine to Africa CDC to support the response to the ongoing mpox outbreak in Africa. In October, Bavarian Nordic was awarded a new joint procurement contract by the European Commission through the Health Emergency Preparedness and Response Authority (HERA), enabling the EU, its member states and additional European countries to purchase up to 8 million doses of smallpox/mpox vaccine over the next four years. Initially, approximately 1.1 million doses have been committed, of which supply of the first 750,000 doses are expected to occur in 2026. The agreement was formally signed in November, following a statutory 10-day standstill period.After serving nearly 20 years as the Vice President of Investor Relations, Rolf Sass Sørensen has decided to leave Bavarian Nordic to pursue other opportunities. A replacement search will be initiated soon.In November, the takeover offer from the consortium consisting of Nordic Capital and Permira was withdrawn following preliminary results of the offer, which confirmed an acceptance rate of 60%, less than the minimum condition of 66 2/3% required for completion. The offer has irrevocably lapsed, and no shares will be acquired under the offer.In November, Chair of the Board, Luc Debruyne decided to step down from the Board with immediate effect. Vice Chair Anne Louise Eberhard was appointed new Chair of the Board.

Attachment Interim Results for the First Nine Months of 2025

Shareholders representing only about 25.7% of the company’s share capital have so far accepted the offer. Anne Czichos via Shutterstock.com. Bavarian Nordic’s board of directors has urged shareholders to accept a sweetened takeover offer as the potential sale of the company continues to stall. A consortium led by Nordic Capital and Permira came back to Bavarian Nordic shareholders with an offer of DKr250 ($39) per share on, increasing its initial bid that failed to win sufficient support from investors in August 2025. At the time, the prospective buyers had offered DKr233 per share for the Danish vaccine specialist. Shares in Bavarian Nordic opened 4% up at DKr240.20 on 16 October compared to a prior market close of DKr230.50. The company has a market cap of Dkr18.5bn. However, shareholders representing only about 25.7% of the company’s share capital have so far accepted the offer, according to a statement by Bavarian Nordic. This is below the 75% threshold that the consortium is asking, revised down from 90% earlier this year. ATP, which is Denmark’s biggest pension fund, holds more than 10% of Bavarian. It said it will maintain its position on not tendering its shares despite the revised offer. “We have noted that the takeover offer has been raised, but our position remains unchanged. ATP still wishes to be a long-term shareholder in Bavarian Nordic,” Claus Møller Berner, deputy director of Danish Equities at ATP, told Pharmaceutical Technology in an emailed statement.

By GlobalData Learn more about Strategic Intelligence Given that ATP is the largest shareholder in the company, its position could influence fellow shareholders. However, several institutional shareholders representing 5.3% of share capital have already moved to accept the offer, meaning appetite for a sale – that would take the company private – still exists. Innosera, a newly formed entity controlled by the consortium, has informed Bavarian that the DKr250 takeover value “is its best and final offer price and will not be increased”. Bavarian’s board has been keen to advance the sale over the line, urging shareholders to accept the offer. “Following the extension of the offer period and the increased offer price, the board of directors maintains its recommendation to shareholders to accept the offer. Based on our view of the company’s fundamental value and in light of the share price level over a longer period prior to the consortium’s takeover bid being made public, we continue to find the offer fair and attractive,” commented Luc Debruyne, board chair at Bavarian Nordic. Bavarian Nordic is known for its travel health and public preparedness vaccines. The company posted total revenue for H1 2025 of DKr3bn, reflecting a 33% increase compared to the same period last year. A busy 2025 of commercial wins for Bavarian Nordic was spearheaded by approval for its chikungunya vaccine Vimkunya in the US, Europe, and the UK. There was also the $160m sale of a priority review voucher , which bolstered cash reserves, in June 2025.
