November 6, 2025 Copenhagen, Denmark;
Interim Report for the Nine Months Ended September 30, 2025

Highlights

• Announcement of Genmab’s proposed acquisition of Merus N.V. (Merus)
• Genmab revenue increased21% compared to the first nine months of 2024, to $2,662 million
• FDA granted BTD to Rina-S^® in advanced endometrial cancer
• Epcoritamab Phase 3 EPCORE^® FL-1 trial met dual primary endpoints of ORR and PFS, demonstrating statistically significant and clinically meaningful differences in both endpoints
• FDA granted priority review of the sBLA for epcoritamab plus R² in patients with relapsed or refractory FL
  
  

“In the third quarter we made advances that underscore the potential of our late-stage portfolio; Epcoritamab moved closer to being available to patients in earlier lines of therapy for follicular lymphoma and Rina-S was granted Breakthrough Therapy Designation (BTD) in advanced endometrial cancer. With robust development plans for both epcoritamab and Rina-S and with Tivdak^® (tisotumab vedotin) now available for prescribing in Germany - our first commercial entry into a European market - we continue to execute on our strategic imperatives to accelerate our late-stage pipeline and maximize our approved medicines to reach more patients,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab. “In addition, our proposed acquisition of Merus provides us with the potential to add petosemtamab, a late-stage asset with two BTDs, to our late-stage portfolio. This proposed transaction is expected to meaningfully accelerate our shift to a wholly owned model, driving sustained growth into the next decade and contributing to our evolution into a global biotechnology leader.”

Financial Performance First Nine Months of 2025

• Revenue was $2,662 million for the first nine months of 2025 compared to $2,198 million for the first nine months of 2024. The increase of $464 million, or 21%, was primarily driven by higher DARZALEX^® and Kesimpta^® royalties achieved under our collaborations with Johnson & Johnson (J&J) and Novartis Pharma AG (Novartis), respectively, and higher EPKINLY^® net product sales.
• Royalty revenue was $2,219 million in the first nine months of 2025 compared to $1,802 million in the first nine months of 2024, an increase of $417 million, or 23%. The increase in royalties was driven by higher net sales of DARZALEX and Kesimpta.
• Net sales of DARZALEX (daratumumab), including sales of the subcutaneous (SC) product (daratumumab and hyaluronidase-fihj, sold under the tradename DARZALEX FASPRO^® in the U.S.) by J&J were $10,448 million in the first nine months of 2025 compared to $8,586 million in the first nine months of 2024, an increase of $1,862 million or 22%.
• Total costs and operating expenses were $1,655 million in the first nine months of 2025 compared to $1,536 million in the first nine months of 2024. The increase of $119 million, or 8%, was driven by the expansion of our product pipeline, including advancement of Rina-S, the continued development of Genmab’s broader organizational capabilities as well as profit-sharing amounts payable to AbbVie Inc. (AbbVie) related to EPKINLY sales.
• Operating profit was $1,007 million in the first nine months of 2025 compared to $662 million in the first nine months of 2024.

As disclosed in Company Announcement No. 46, Genmab and Merus announced that the companies entered into a transaction agreement pursuant to which Genmab intends to acquire all the shares of Merus, a clinical-stage biotechnology company with its late-stage breakthrough therapy asset petosemtamab, which is in Phase 3 development, for USD 97.00 per share in an all-cash transaction representing a transaction value of approximately USD 8.0 billion. The transaction is not subject to a financing condition. Consideration is expected to be funded through a combination of cash on hand and approximately $5.5 billion of non-convertible debt financing. Genmab has obtained a funding commitment from Morgan Stanley Senior Funding, Inc. for this amount. The financing package includes a meaningful portion of prepayable debt, in line with Genmab’s commitment to deleveraging with a target of gross leverage <3x within two years after the closing of the proposed transaction. On October 21, 2025, a wholly owned subsidiary of Genmab commenced a tender offer for 100% of Merus’ common shares. The proposed transaction is anticipated to close by early in the first quarter of 2026, subject to the satisfaction of customary closing conditions for similar transactions. In addition to the Company Announcement, further information may be found in Notes 1 and 2, below.
