Financial Performance First Half of 2024

• Revenue was DKK 9,545 million for the first six months of 2024 compared to DKK 7,003 million for the first six months of 2023. The increase of DKK 2,542 million, or 36%, was primarily driven by higher DARZALEX^® (daratumumab) and Kesimpta^® (ofatumumab) royalties achieved under our collaborations with Janssen Biotech, Inc. (Janssen) and Novartis Pharma AG (Novartis), respectively, and increased EPKINLY net product sales.
• Royalty revenue was DKK 7,673 million in the first six months of 2024 compared to DKK 5,886 million in the first six months of 2023, an increase of DKK 1,787 million, or 30%. The increase in royalties was driven by higher net sales of DARZALEX and Kesimpta.
• Net sales of DARZALEX, including sales of the subcutaneous (SC) product (daratumumab and hyaluronidase-fihj, sold under the tradename DARZALEX FASPRO^® in the U.S.), by Janssen were USD 5,570 million in the first six months of 2024 compared to USD 4,695 million in the first six months of 2023, an increase of USD 875 million or 19%.
• Total costs and operating expenses were DKK 7,104 million in the first six months of 2024 compared to DKK 5,118 million in the first six months of 2023. The increase of DKK 1,986 million, or 39%, was driven by the expansion of our product pipeline, EPKINLY post-launch activities in the U.S. and Japan, the continued development of Genmab’s broader organizational capabilities and related increase in team members to support these activities, as well as profit-sharing amounts payable to AbbVie Inc. (AbbVie) related to EPKINLY sales.
• Operating profit was DKK 2,441 million in the first six months of 2024 compared to DKK 1,885 million in the first six months of 2023.
• Net financial items resulted in income of DKK 1,402 million for the first six months of 2024 compared to DKK 75 million in the first six months of 2023. The increase of DKK 1,327 million was primarily driven by movements in USD to DKK foreign exchange rates impacting Genmab’s USD denominated cash and cash equivalents and marketable securities, with strengthening of the USD/DKK rate in the first six months of 2024 compared to the weakening of the USD/DKK rate in the first six months of 2023.

Significant Event Post-quarter End

• August: Genmab announced that it will assume sole responsibility for the continued development and potential commercialization of acasunlimab. BioNTech SE (BioNTech) has opted not to participate in the further development of the acasunlimab program under the parties’ existing collaboration agreement. The program will be subject to payment of certain milestones and a tiered single-digit royalty on net sales by Genmab to BioNTech. While the emerging clinical profile of acasunlimab is encouraging, BioNTech informed the company that it has taken this decision for reasons relating to its portfolio strategy. The companies’ long-standing collaboration in antibody science remains in place, and both parties will continue with the existing programs under development under their existing agreements, which were expanded in 2022.

Outlook
As announced in Company Announcement No. 52, Genmab is updating its 2024 financial guidance.

*Net Product Sales and Collaboration Revenue consists of EPKINLY Net Product Sales in the U.S. and Japan and Tivdak (Genmab’s share of net profits) in the U.S.
**Operating Expenses Range excludes Cost of Product Sales Range, which is included in Gross Profit Range
