Fresenius SE & Co. KGaA (XETR: FRE; OTCM: FSNUY) today announced that it has acquired the remaining 45% of mAbxience Holding S.L. (mAbxience) from Insud Pharma S.L. and Invim Corporativo, S.L. for a total consideration of up to €750 million including a contingent payment of €50 million upon site-approvals. The transaction was signed and completed on 30 September 2026 with no regulatory approvals required.

Fresenius acquired a 55% majority stake in mAbxience in August 2022 and has controlled and consolidated the business since then. Full ownership completes that structure: the biosimilars platform is now wholly owned within Fresenius Kabi’s Biopharma business, which covers the full value chain from research through to commercialization.

The acquisition builds on a successful partnership that has already delivered important development, manufacturing, technology-transfer, and regulatory milestones. Taking full ownership gives Fresenius the entire economic benefit of the platform and greater strategic flexibility to invest in manufacturing capacity, select future biosimilar opportunities, and pursue licensing partnerships at a time when a large wave of biologics is losing exclusivity. This fast-growing market is expected to grow approximately six times by 2035 to more than €180 billion. Bringing the organizations together under full ownership creates a stronger platform to enhance quality, supply resilience, and operational freedom, while supporting future innovation, and broader patient access to high-quality biosimilars. The transaction is consistent with the capital allocation priorities set out under #FutureFresenius.

Michael Sen, Chief Executive Officer of Fresenius, said: “Completing the acquisition of mAbxience marks the next milestone in building a leading, vertically integrated biopharma business at scale. When we first invested in mAbxience four years ago, the market opportunity was promising but still evolving. Our initial majority stake gave us access to a highly competitive platform while managing risk. Since then, the market has developed strongly, mAbxience has delivered, and Fresenius now has the financial strength to take this next step. Full ownership gives us complete control over cost, capacity and launch timing, and full economic benefit, as the next wave of biologics loses exclusivity. For patients, that means dependable access to high-quality biosimilars; for shareholders, it is a disciplined investment in a business we know well.”

Jurgen Van Broeck, Chief Executive Officer of mAbxience, said: “mAbxience was founded to serve patients, while proving that world-class biologics could be developed and manufactured at a cost the world could afford. Since 2022, our partnership with Fresenius has demonstrated the strength of combining our people, expertise, and capabilities. I would also like to recognize and thank Insud Pharma for its support and commitment over the past decade. The success of mAbxience today is built on the vision, dedication and hard work of many people who have contributed to this journey from the very beginning. Full ownership is the natural next step and creates an even stronger platform for innovation, growth, and long-term impact for patients, customers, and partners. As we begin this next chapter together, we will continue to build on the entrepreneurial spirit, scientific expertise, and commitment to patients that have driven mAbxience’s success.”

mAbxience is a leading global biopharmaceutical company that operates three multi-product state-of-the-art drug substance facilities in Spain and Latin America and employs over 1,300 people. mAbxience develops and manufactures biosimilar monoclonal antibodies and provides contract development and manufacturing services to partners. In 2025 mAbxience generated more than €320 million in revenue and contributed earnings before interest, taxes, depreciation, and amortization (EBITDA) margin that was accretive to the overall Fresenius Kabi margin. Its portfolio comprises four products on the market and eight candidates in development. Together with Fresenius Kabi’s development, regulatory, and commercial capabilities it covers the full value chain from laboratory to patient.

Jurgen Van Broeck, Chief Executive Officer of mAbxience, will continue to lead the business, reporting to Dr. Sang-Jin Pak, President Biopharma at Fresenius.

Full ownership positions the platform for further scale, including pipeline expansion opportunities, within Fresenius’ unchanged financial framework.

Financial Considerations

• Consideration: Up to €750 million in cash, including a contingent payment of €50 million upon site-approvals.
• Funding: Available liquidity and operating cash flow. No new financing was required.
• Balance sheet: The consideration settles the put option liability over the 45% non-controlling interest recognized in the Group’s consolidated balance sheet. Following the transaction, net debt to EBITDA is expected to increase by approximately 20 basis points, while leverage for the full year is expected to be towards the lower end of the self-imposed target corridor of 2.5x to 3.0x.
• Accounting: Under International Financial Reporting Standards, the acquisition of a non-controlling interest is an equity transaction; no goodwill arises. A 45% non-controlling interest has been presented to date: The transaction is expected to be immediately accretive to Group core earnings per share.
• Returns: The investment is expected to further improve the return on invested capital (ROIC) already above Fresenius’ cost of capital after the integration, in line with the Group’s capital allocation criteria.
• Credit ratings: Fresenius is rated BBB (outlook positive) by S&P, Baa3 (outlook stable) by Moody’s and BBB- (outlook positive) by Fitch. A strong balance sheet and continued deleveraging remain priorities.

 Guidance: No change to full-year 2026 guidance or to the 2030 Biopharma ambition of approximately doubling revenue compared with 2025 at an EBIT margin of around 20%.
