Stabilisation period begins

With reference to the offering circular (the “Offering Circular”) as published by BioMar Group A/S (“BioMar”) and company announcements no. 1-2026 dated 19 May 2026 related to the publication of the Offering Circular for BioMar’s initial public offering (the “Offering”) and admission to trading and official listing of the shares of BioMar on Nasdaq Copenhagen and no. 2-2026 dated 28 May 2026 related to the result of the Offering, BioMar has received notification regarding the beginning of the stabilisation period from DNB Carnegie Investment Bank, Filial af DNB Carnegie Investment Bank AB (PUBL), Sverige ("DNB Carnegie") acting as stabilising manager (the “Stabilising Manager”) in the Offering.

Information about BioMar

BioMar is a leading global aquafeed solutions provider, focusing on the attractive segment of high‑value species such as salmon, warm‑water shrimp, trout, sea bass and sea bream and many other high-value fish. BioMar operates 16 feed production facilities and five technology centres located in the major aquaculture hubs in Europe, Latin America and Asia. In total, BioMar supplies high-value feed for more than 45 different species, offering its products in more than 90 countries to approx. 1,400 customers.

Since BioMar became part of Aktieselskabet Schouw & Co. (“Schouw & Co.”) in 2005, consolidated revenue has grown by 10% per year on average, reaching a revenue of DKK 16.5 billion in 2025. Earnings (EBIT) have grown even faster, with an annual average growth rate of 12%, exceeding DKK 1.1 billion in 2025. BioMar’s full 2025 Annual Report and Q1 2026 interim report can be found at www.investors.biomar.com

Global demand for protein is rising due to an expanding global population, with aquaculture emerging as one of the fastest growing and most sustainable sources of non-plant proteins. This positions aquaculture as a key driver in bridging the gap between rising protein demand and constrained supply.

Over the years, it has become evident that feed is far more than an enabler of growth. It is also impacting the quality of seafood end-products, and with the right nutritional solutions, fish and shrimp can thrive, build greater resilience, and mitigate health challenges, all while lowering environmental impact through the use of circular and restorative raw materials. Feed is particularly important to the aquaculture value chain, generally accounting for up to 80% of farmers of high value species’ carbon footprint and more than 50% of their operating expenses.

BioMar’s position in the value chain, its diversification across species and geographies, as well as strong innovation and sustainability credentials allow it to stay at the forefront of the sector’s evolution from commoditised feed to sophisticated ingredients solutions, resulting in greater visibility on earnings and stronger resilience.
