Genmab A/S (GMAB) raises 2026 outlook on DARZALEX and EPKINLY growth
Rhea-AI Filing Summary
Genmab A/S reported 25% year-on-year revenue growth for the first half of 2026, with revenue of $2,051 million versus $1,640 million, driven mainly by higher DARZALEX and Kesimpta royalties and rising EPKINLY net product sales. Royalty revenue reached $1,708 million, while global EPKINLY/TEPKINLY sales were $312 million and Tivdak $84 million.
Operating profit was $555 million and adjusted operating profit $656 million, compared with $548 million and $554 million, respectively, but net profit declined to $356 million from $531 million as net financial items moved to a $186 million loss following the $5.5 billion Merus acquisition, leaving $5,135 million of borrowings and $174 million of interest expense in the period.
Genmab raised its 2026 outlook, guiding revenue to $4,325–4,525 million and adjusted operating profit to $1,065–1,385 million, primarily on stronger DARZALEX royalties and EPKINLY sales. Clinically, positive Phase 3 results for epcoritamab plus lenalidomide in relapsed/refractory DLBCL and continued advancement of Rina-S and petosemtamab underscore a broad late-stage oncology pipeline.
Positive
- Revenue up 25% to $2,051 million in the first six months of 2026 versus $1,640 million, driven mainly by higher DARZALEX and Kesimpta royalties and 48% growth in global EPKINLY/TEPKINLY sales to $312 million.
- 2026 guidance raised, with revenue now $4,325–4,525 million and adjusted operating profit $1,065–1,385 million, primarily reflecting stronger DARZALEX royalties and higher EPKINLY net product sales.
Negative
- Net profit fell to $356 million in the first six months of 2026 from $531 million, as net financial items swung to a $186 million loss driven by $174 million of interest expense and $43 million of amortization on new borrowings.
- Higher leverage and softer cash generation, with borrowings at $5,135 million and net cash provided by operating activities dropping to $54 million from $349 million over the comparable period.

Breakthrough Therapy Designation medical
"Rina-S, GEN1184 – ADC with FDA Fast Track and Breakthrough Therapy Designations"
A breakthrough therapy designation is a regulatory fast-track given to a drug or treatment that shows early signs of providing a major improvement over existing options for a serious condition. Think of it as a VIP lane that can speed up development and more intensive guidance from regulators, which matters to investors because it can shorten time to market, reduce development risk and potentially increase a company’s value — though it does not guarantee approval.
Adjusted operating profit financial
"Genmab expects its 2026 adjusted operating profit to be in the range of $1.07 - 1.39 billion"
Adjusted operating profit is a measure of a company’s routine profit from its core business activities after removing one‑time events, unusual costs or non‑cash items so the result reflects ongoing operations. Think of it like judging a car’s normal fuel efficiency after ignoring a single visit to the body shop; investors use it to compare underlying profitability across periods or peers and to judge whether the business is sustainably earning money, but the specific exclusions can be subjective.
smoldering multiple myeloma medical
"the only approved therapy for the treatment of patients with high-risk smoldering multiple myeloma"
cash flow hedges financial
"Cash flow hedges Gross deferred gains/(losses) on cash flow hedges"
A cash flow hedge is an accounting label companies use when they enter financial contracts—like currency or interest-rate agreements—to protect expected future cash payments or receipts from unpredictable moves. For investors, it signals that the company is trying to smooth out future cash variability (think of locking in a price to avoid surprises), which can reduce reported profit swings but also means the company has exposure to derivative instruments and their associated risks.
interest rate swaps financial
"Genmab’s designated derivative contracts consist of interest rate swaps"
A contract between two parties to exchange streams of interest payments, typically swapping a fixed-rate payment for a floating-rate payment or vice versa. Think of it like two neighbors agreeing to trade the type of mortgage payments they make to reduce uncertainty or take advantage of expected rate moves; investors care because swaps change a company’s borrowing costs and risk exposure, which can materially affect cash flow, creditworthiness, and valuation.

At the same time, new data further support the development of Rina-S® (rinatabart sesutecan) in combination in advanced ovarian cancer. Together, these results reflect our continued commitment to delivering meaningful advances for patients,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

Our Adjusted operating expenses and Adjusted operating profit excludes acquisition and integration related charges and amortization of acquired intangible assets.

Genmab is updating its revenue, operating expenses and operating profit guidance for 2026. The improved guidance is driven by higher total royalty revenues from DARZALEX and net sales of EPKINLY.
Revenue
Genmab expects its 2026 revenue to be in the range of $4.33 - 4.53 billion, an increase to the previous guidance range of $4.07 - 4.40 billion. Genmab’s projected revenue growth for 2026 is driven by higher royalties, net product sales and collaboration revenue.
Genmab expects its 2026 revenue to be in the range of $4.33 - 4.53 billion, an increase to the previous guidance range of $4.07 - 4.40 billion. Genmab’s projected revenue growth for 2026 is driven by higher royalties, net product sales and collaboration revenue.
Royalty growth relates mainly to DARZALEX and Kesimpta net sales growth. Net product sales/Collaboration revenue growth is driven by strong performance for EPKINLY.
Genmab’s projected revenue for 2026 primarily consists of DARZALEX royalties of approximately $2.83 billion at the midpoint. Such royalties are based on estimated DARZALEX 2026 net sales of $16.50 - 16.90 billion. DARZALEX royalties are partly offset by Genmab’s share of J&J’s royalty payments to Halozyme Therapeutics, Inc. (Halozyme) in connection with subcutaneous (SC) net sales as well as royalty reduction in countries and territories where there is no Genmab patent coverage.
The remainder of Genmab’s revenue consists primarily of royalties from TEPEZZA®, RYBREVANT®, TECVAYLI®, TALVEY®, TEPKINLY and BIZENGRI®, net product sales of EPKINLY and collaboration revenue from Tivdak, reimbursement revenue and milestones.
Adjusted Operating Expenses
Genmab is updating its 2026 adjusted operating expenses to be in the range of $2.81 - 2.95 billion, an increase to the previous guidance range of $2.71 - 2.91 billion. The increase in adjusted operating expenses is primarily related to investments in late-stage programs and launch readiness in key markets.

On December 12, 2025, Genmab closed the acquisition of Merus, including its late-stage breakthrough therapy asset petosemtamab. In order to finance the acquisition, Genmab borrowed $5.5 billion and utilized cash on hand. Genmab’s financial results of the first six months of 2026 reflect the impact of these transactions.
Revenue
Genmab’s revenue was $2,051 million for the first six months of 2026 compared to $1,640 million for the first six months of 2025. The increase of $411 million, or 25%, was primarily driven by higher DARZALEX and Kesimpta royalties achieved under our collaborations with J&J and Novartis, respectively, and increased EPKINLY net product sales. This increase was partly offset by reduced reimbursement revenue of $16 million, which was primarily driven by the acasunlimab program.

Royalties
Royalty revenue amounted to $1,708 million in the first six months of 2026 compared to $1,378 million in the first six months of 2025. The increase of $330 million, or 24%, was primarily driven by higher DARZALEX and Kesimpta royalties achieved under our collaborations with J&J and Novartis, respectively.

J&J’s net sales of DARZALEX were $8,171 million in the first six months of 2026 compared to $6,776 million in the first six months of 2025. The increase of $1,395 million, or 21%, was driven by market share gains and market growth in all regions. Royalty revenue on net sales of DARZALEX was $1,306 million in the first six months of 2026 compared to $1,088 million in the first six months of 2025, an increase of $218 million, or 20%. The percentage increase in royalties is lower than the percentage increase in the underlying net sales primarily due to the tiered royalty rates, Genmab’s Halozyme royalty reductions in connection with the increase in SC product net sales and royalty reductions on net sales in countries and territories where there is no Genmab patent coverage. Under our license agreement with Janssen for DARZALEX, for purposes of calculating

royalties due to Genmab, DARZALEX net sales for non-U.S. dollar denominated currencies are translated to U.S. dollar at a specified annual Currency Hedge Rate.
Novartis’ net sales of Kesimpta were $2,588 million in the first six months of 2026 compared to $1,976 million in the first six months of 2025. The increase of $612 million, or 31%, was primarily driven by increased demand and strong access. Royalty revenue on net sales of Kesimpta was $259 million in the first six months of 2026 compared to $198 million in the first six months of 2025, an increase of $61 million, or 31%.
Amgen’s net sales of TEPEZZA were $1,066 million in the first six months of 2026 compared to $886 million in the first six months of 2025, an increase of $180 million, or 20%. Royalty revenue on net sales of TEPEZZA was $57 million in the first six months of 2026 compared to $45 million in the first six months of 2025, an increase of $12 million, or 27%. The percentage increase in royalties is higher than the percentage increase in underlying net sales primarily due to the timing of adjustments recognized during the respective periods.
Other royalties consist of royalties from net sales of RYBREVANT, TECVAYLI, TALVEY, TEPKINLY and BIZENGRI. These royalties were not material for the first six months of 2026 or 2025.
Royalty revenue fluctuations from period to period are driven by the level of product net sales, foreign currency exchange rate movements and more specifically to DARZALEX, the contractual arrangement related to annual Currency Hedge Rate, Genmab’s share of J&J’s royalty payments to Halozyme in connection with SC product net sales and the level of royalty reductions on net sales in countries and territories where there is no patent protection.
Net Product Sales
Global net product sales include sales of EPKINLY in the U.S. and Japan and Tivdak in Japan and Europe.
EPKINLY/TEPKINLY
Global net sales of EPKINLY/TEPKINLY were $312 million in the first six months of 2026 compared to $211 million in the first six months of 2025, an increase of $101 million or 48%, driven by strong growth in both 3L+ DLBCL and 3L+ FL, as well as 2L FL, which was approved in the U.S. in November 2025. Net product sales of EPKINLY in the U.S. and Japan recorded by Genmab were $242 million in the first six months of 2026 compared to $175 million in the first six months of 2025.

Milestone Revenue
Milestone revenue was $26 million in the first six months of 2026 compared to $13 million in the first six months of 2025, an increase of $13 million, or 100%. Milestone revenue in the first six months of 2026 was primarily driven by $23 million of milestones received from collaboration partners acquired as part of the Merus acquisition compared to a J&J milestone for $10 million in the first six months of 2025.
Milestone revenue may fluctuate significantly from period to period due to both the timing of achievements and the varying amount of each individual milestone under our license and collaboration agreements.
Collaboration Revenue
Collaboration revenue, which primarily reflects 50% of gross profit from net sales of Tivdak in the U.S. by Pfizer, was $36 million in the first six months of 2026 compared to $37 million in the first six months of 2025, a decrease of $1 million, or 3%. The decrease was primarily driven by lower Tivdak net sales, partially offset by Genmab's 50% share of a $10 million milestone received by Pfizer following regulatory approval of Tivdak in China during the second quarter of 2026.
Refer to Financial Statement Note 2 in this interim report for further details about revenue.

Interest and Other Financial Income
Interest and Other Financial Income is comprised of interest income on cash and marketable securities and other financial gains. The decrease of $8 million for the first six months of 2026 compared to the first six months of 2025, was primarily driven by a $31 million decrease in interest income on marketable securities due to the liquidation of all marketable securities to contribute to the funding of the Merus acquisition completed in December 2025. This decrease was partially offset by an increase of $23 million due to a modification gain related to the Term B Loans Amended Credit Agreement entered into in June 2026.
Refer to Financial Statement Note 7 in this interim report for further details about borrowings.
Interest and Amortization Expense on Borrowings
The increase of $217 million for the first six months of 2026 compared to the first six months of 2025, was due to $174 million of interest expense and $43 million of amortization of fees associated with the debt issued in December 2025 in connection with the financing of the Merus acquisition as well as the Term B Loans Amended Credit Agreement in June 2026.

Interest and Other Financial Income
Interest and Other Financial Income is comprised of interest income on cash and marketable securities and other financial gains. The net increase of $11 million for the second quarter of 2026 compared to the second quarter of 2025, was primarily due to the $23 million modification gain related to the Term B Loans Amended Credit Agreement entered into in June 2026.

Refer to Financial Statement Note 7 in this interim report for further details about borrowings.
Interest and Amortization Expense on Borrowings
The increase of $109 million for the second quarter of 2026 compared to the second quarter of 2025, was due to $85 million of interest expense and $24 million of amortization of fees associated with the debt issued in December 2025 in connection with the financing of the Merus acquisition as well as the Term B Loans Amended Credit Agreement in June 2026. There was no interest expense or amortization of fees on borrowings for the second quarter of 2025 as Genmab did not have any borrowings prior to December 2025.

Foreign Exchange Rate Loss/Gain, Net
Foreign exchange rate loss, net, was $6 million in the second quarter of 2026 compared to foreign exchange rate gain, net of $6 million in the second quarter of 2025. The decrease was primarily driven by foreign exchange rate movements impacting Genmab’s EUR and DKK denominated assets and liabilities. The EUR and DKK weakened against the USD in the second quarter of 2026 compared to strengthening against the USD in the second quarter of 2025.
Corporate Tax
Corporate tax expense for the first six months of 2026 was $13 million compared to $136 million for the first six months of 2025. The decrease in corporate tax expense is the result of Genmab’s lower net profit before tax and decrease in the estimated annual effective tax rate in the first six months ended 2026 of 3.6%, compared to 20.3% in the first six months of 2025. The lower estimated annual effective tax rate was primarily attributable to the Merus integration that allows for the partial recognition of previously unrecognized tax benefits. Accordingly, the estimated annual effective tax rate for the first six months ended 2026 is not indicative of the Company's expected annual effective tax rate in future periods. The annual effective tax rate may experience further volatility from the statutory rate as Merus integration continues.

tax benefits. Accordingly, the estimated annual effective tax rate for the second quarter of 2026 is not indicative of the Company's expected annual effective tax rate in future periods. The annual effective tax rate may experience further volatility from the statutory rate as Merus integration continues.
Net Profit
Net profit for the first six months of 2026 was $356 million compared to $531 million in the first six months of 2025. The decrease was driven by the items described above. Net profit for the second quarter of 2026 was $303 million compared to $336 million in the second quarter of 2025. The decrease was driven by the items described above.

Net cash provided by operating activities is primarily related to our operating profit, changes in operating assets and liabilities, reversal of net financial items, and adjustments related to non-cash transactions. The $295 million decrease in net cash provided by operating activities is primarily driven the following items: $298 million decrease in net profit before tax (as described above), a $320 million unfavorable change in other payables primarily reflecting increased spend related to petosemtamab and Rina-S, payments for termination costs associated with the discontinuance of the acasunlimab and other programs and payments related to compensation and bonuses, and $191 million in interest paid, primarily related to borrowings and payment of Merus transaction related costs. These items were partially offset by $305 million increase to net financial items, primarily related to $217 million of interest expense and amortization of fees associated with the debt issued in December 2025 and an increase of $219 million as a result of lower corporate taxes paid in the first six months of 2026 compared to the first six months of 2025.
Net cash used in investing activities primarily reflects differences between the proceeds received from the sale and maturity of our investments and amounts invested, and the cash paid for investments in tangible and intangible assets. The $10 million decrease in net cash used in investing activities was primarily driven by lower investments in intangible and tangible assets of $32 million as well as a distribution from our fund investments of $5 million during the first six months of 2026 compared to the first six months of 2025, partially offset by the absence of marketable securities activity during the first six months of 2026 following the liquidation of all marketable securities to contribute to the funding of the Merus acquisition completed in December 2025, compared to net marketable securities sold of $26 million in the first six months of 2025.

Interim Report for the First Half of 2026
Net cash used in financing activities is primarily related to the repayments of borrowings, purchase of treasury shares, exercise of warrants, lease payments, and payment of withholding taxes on behalf of employees on net settled Restricted Stock Units (RSUs). The $167 million decrease in net cash used in financing activities between the periods was primarily driven by $310 million of higher cash paid for the purchase of treasury shares during the first six months of 2025 compared to the first six months of 2026 due to the timing of share repurchases, partially offset by $125 million of cash principal repayments on borrowings during the first six months of 2026 compared to none in the first six months of 2025 as Genmab did not have any borrowings prior to December 2025.
Balance Sheet
As of June 30, 2026, total assets were $12,515 million compared to $12,873 million on December 31, 2025. The decrease of $358 million, or 3% was primarily driven by a decrease in other intangible assets of $251 million due to negative foreign exchange rate impacts from the weakening of the EUR against the USD on our EUR denominated intangible assets, a decrease in cash and cash equivalents of $212 million due to working capital movements, repayments of principal and interest related to borrowings, repurchases of treasury shares, and corporate taxes paid, partly offset by operating profit generated during the period. These decreases were partly offset by an increase in receivables and other current assets of $100 million due to higher DARZALEX and Kesimpta royalties achieved under our collaborations with J&J and Novartis, driven by higher net sales in the second quarter of 2026 as compared to the fourth quarter of 2025, as well as higher trade receivables resulting from increased EPKINLY sales during the same period. As of June 30, 2026, cash and cash equivalents in Genmab’s Condensed Consolidated Balance Sheets includes $30 million of restricted cash balances for funds held in escrow related to the acquisition of ProfoundBio.

As of June 30, 2026, total liabilities were $6,558 million compared to $7,026 million on December 31, 2025. The decrease in total liabilities of $468 million was primarily driven by a decrease in current other payables of $262 million, primarily related to higher accruals recorded at year-end 2025 related to accrued termination costs associated with the discontinuance of the acasunlimab and other programs during the fourth quarter of 2025, accrued compensation and bonuses and accrued withholding tax on Merus related option payments paid in the first six months of 2026, as well as decreases in non-current and current borrowings of $139 million and corporate tax payable of $43 million.
Shareholders’ equity as of June 30, 2026, was $5,957 million compared to $5,847 million on December 31, 2025. The increase of $110 million, or 2%, was primarily driven by Genmab’s net profit for the period and share-based compensation expenses, partly offset by negative foreign exchange rate impacts affecting the translation of our subsidiaries into USD, mainly the EUR based subsidiaries as a result of the weakening of the EUR against the USD and the purchase of treasury shares.
Employees
Employees comprise individuals who are employed by Genmab and excludes contractors and consultants. As of June 30, 2026, the total number of employees was 3,119 compared to 2,639 as of June 30, 2025. The increase was primarily driven by the continued investment and expansion of our R&D product portfolio and global commercialization capabilities, primarily related to Rina-S and petosemtamab. Also contributing to the increase in employees was the acquisition of Merus, which occurred during the fourth quarter of 2025.

Legal Matters
Genmab is involved in pending legal proceedings arising out of the normal conduct of its business, the most significant of which are described below. These matters involve highly complex issues which are often subject to substantial uncertainties and, therefore, the probability of a loss, if any, being sustained and/or an estimate of the amount of any loss is difficult to ascertain. In cases that have been settled or adjudicated, or where quantifiable fines and penalties have been assessed and which, in each case, are not subject to appeal, or where a loss is probable and we are able to make a reasonable estimate of the loss, Genmab records the loss absorbed or makes a provision for its best estimate of the expected loss. Management has assessed the claims below on that basis and no provisions have been recorded.
Chugai Patent Infringement Complaint
In 2024, Chugai filed a lawsuit in the Tokyo District Court in Japan against AbbVie’s and Genmab’s Japanese subsidiaries asserting that their activities related to EPKINLY (epcoritamab) in Japan infringe two Japanese patents held by Chugai and claiming damages and injunctive relief. In September 2025, Chugai filed two further lawsuits in the same court, against the same parties and with similar assertions, based on two newly granted Japanese patents held by Chugai which are similar to the patents from the original lawsuit.
Genmab and AbbVie believe that all four of the patents are invalid and/or not infringed and intend to vigorously defend the claims.
AbbVie Rina-S Trade Secret Complaint
During the first quarter of 2025, AbbVie filed a complaint in the U.S. District Court for the Western District of Washington (Seattle) naming Genmab A/S; ProfoundBio U.S. Co.; ProfoundBio (Suzhou) Co., Ltd.; and former AbbVie employees as defendants. AbbVie alleges that the defendants have misappropriated AbbVie’s alleged trade secrets relating to the use of disaccharides to improve the hydrophilicity of drug-linkers in ADCs in connection with Rina-S and other ADC pipeline products of ProfoundBio. AbbVie is seeking damages and broad injunctive relief. AbbVie is not asserting or enforcing any patent rights against the defendants, and to Genmab’s knowledge, AbbVie has not pursued any development of products incorporating their alleged trade secrets. During the fourth quarter of 2025, AbbVie filed a complaint with the U.S. International Trade Commission (ITC) under Section 337 of the Tariff Act against ProfoundBio US Co.; ProfoundBio (Suzhou) Co., Ltd.; Genmab A/S; Genmab B.V.; and Genmab US, Inc., seeking to exclude certain antibody drug conjugate products from importation into the United States. The district court action was stayed during the pendency of the ITC investigation. The ITC complaint was based on allegations substantially similar to those asserted in the Washington district court action. During the second quarter of 2026, AbbVie withdrew its ITC complaint and filed an unopposed motion to terminate the investigation which will bring the ITC matter to a close. AbbVie has indicated its intention to resume its case in the district court.
Genmab categorically refutes these allegations and will vigorously defend the company against AbbVie’s claims.

Interim Report for the First Half of 2026
NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
Note 1 - Basis of Presentation
Accounting Policies
These interim financial statements of the Genmab Group (Genmab or the Company) have been prepared in accordance with IAS 34 (Interim Financial Reporting) as issued by the International Accounting Standards Board (IASB) and in accordance with IAS 34 as endorsed by the European Union (EU) and additional Danish disclosure requirements for interim reports of listed companies. The interim report has not been audited or reviewed by Genmab’s external auditors.
The interim report has been prepared using the same accounting policies as outlined in Section 1 – Basis of Presentation in the financial statements in the Genmab 2025 Annual Report (Annual Report), except as noted below. A number of amended standards became applicable for the current reporting period. There was no impact to Genmab’s financial statements as a result of adopting these amended standards. These interim financial statements should be read in conjunction with the Annual Report.
(In all accompanying tables, amounts of U.S. dollars are expressed in millions, except per share amounts, unless otherwise noted).
Derivative Financial Instruments
The Company is exposed to certain risks relating to its ongoing financial arrangements. The risk managed using derivative instruments is to reduce variability in interest cash flows on its floating-rate debt. Interest rate swaps are entered into to manage interest rate risk associated with the Company’s floating-rate debt. The use of financial derivatives is governed by the Company’s policies approved by the Board of Directors, which provide written principles on the use of financial derivatives consistent with the Company’s risk management strategy. As a matter of policy, Genmab does not use highly leveraged derivative instruments, nor does Genmab use financial instruments for speculative purposes.
IFRS 9 “Financial Instruments” requires entities to recognize all derivative instruments as either assets or liabilities in the Condensed Consolidated Balance Sheets at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship.
The derivatives are designated as cash flow hedges and qualify for hedge accounting treatment. Changes in the fair value of derivative hedging instruments are initially recognized in Other Comprehensive Income (“OCI”) to the extent that the hedge is effective, and accumulated in Other reserves (net of taxes), a component of equity. Amounts accumulated in equity are subsequently reclassified to net profit in the period(s) in which the hedged item affects net profit, and are presented in the same line item in the Condensed Consolidated Statements of Comprehensive Income as the underlying hedged item (i.e., in “interest expense on borrowings” when the hedged transactions are interest cash flows associated with floating-rate debt).To the extent that the hedge is ineffective, changes in fair value are recognized in the Condensed Consolidated Statements of Comprehensive Income within Financial Income/Financial Expense.
Hedge effectiveness is determined at the inception of the hedge relationship and through periodic prospective effectiveness assessments to ensure that an economic relationship exists between the hedged item and hedging instrument at inception of and throughout the hedged term.
The hedge ratio for each designation will be established by comparing the quantity of the hedging instrument and the quantity of the hedged item to determine their relative weighting. For all of the Company’s existing hedge relationships the hedge ratio has been determined as 1:1. Designated hedges are expected to be effective and therefore the impact of ineffectiveness on profit and loss is not expected to be material.
Hedge accounting is discontinued prospectively when the hedging instrument expires or is sold, terminated, exercised or no longer qualifies for hedge accounting. When hedge accounting is discontinued, any gain or loss

Interim Report for the First Half of 2026
recognized in Other Comprehensive Income at that time remains in equity and is recognized in the Condensed Consolidated Statements of Comprehensive Income when the hedged transaction is ultimately recognized in profit or loss.
If it becomes probable that a forecasted transaction will not occur, previously deferred gains and losses related to those forecasted transactions would be recognized in profit or loss in the Condensed Consolidated Statements of Comprehensive Income in the current period.
Genmab’s designated derivative contracts consist of interest rate swap agreements, which effectively modify the Company’s exposure to interest rate risk by converting a portion of the Company’s floating-rate debt to a fixed-rate basis (for interest rate swap arrangements) for approximately two years, thus reducing the impact of interest-rate changes on future interest expense. These agreements involve the receipt of floating-rate amounts in exchange for fixed-rate interest payments without an exchange of the underlying notional amount.
Information about Geographical Areas
Genmab is managed and operated as one business unit, which is reflected in the organizational structure and internal reporting. No separate lines of business or separate business entities have been identified with respect to any licensed products, product candidates, product sales or geographical markets and no segment information is currently prepared for internal reporting. Refer to Note 2.2 in the Annual Report for further details.

The increase in net products sales was primarily driven by sales of EPKINLY in the U.S. and Japan of $242 million in the first six months of 2026 compared to $175 million in the first six months of 2025.

Interim Report for the First Half of 2026
Contract Liabilities
Genmab has contract liabilities primarily associated with the AbbVie Agreement and Gilead Agreement (assumed through the acquisition of Merus in the fourth quarter of 2025). As part of the continued evaluation of these contract liabilities during the first six months of 2026, Genmab’s classification of contract liabilities reflects the current estimate of research and development activities as of June 30, 2026. Contract liabilities related to AbbVie and Gilead have been recognized as reimbursement revenue in the Condensed Consolidated Statements of Comprehensive Income as the performance obligations have been satisfied. The amounts recognized in the first six months of 2026 and 2025 were not material.
Refer to Note 2.1 in the Annual Report for further details regarding revenue.

Interim Report for the First Half of 2026
Other Intangible Assets
The decrease in the gross carrying value of other intangible assets during the first six months of 2026 was primarily driven by negative foreign exchange rate movements resulting from the weakening of the EUR against the USD, mainly related to petosemtamab (acquired IPR&D) and the technology platform acquired as part of the Merus acquisition completed in December 2025.
Amortization expense was $25 million and $7 million for the first six months of 2026 and 2025 respectively. In the first six months of 2026, $3 million was recorded in Cost of product sales and $22 million was recorded in Research and development expenses in the Condensed Consolidated Statements of Comprehensive Income. In the first six months of 2025, all amortization expense of $7 million was recorded in Research and development expenses in the Condensed Consolidated Statements of Comprehensive Income. The amortization included in Cost of product sales relates to amortization of commercialized intangible assets.
Goodwill
The carrying amount of goodwill, which relates to the acquisition of ProfoundBio during the second quarter of 2024, was $355

The non-current portion of $3 million and the current portion of $7 million are recorded in the Condensed Consolidated Balances sheets in Receivables & other non-current assets and Receivables & other current assets, respectively. Refer to Note 1 and Note 8 in this interim report for further details regarding Genmab’s derivative financial instruments.
Other Investments
Other investments primarily consist of investments in certain strategic investment funds. Genmab’s share of the fair value of these fund investments is determined based on the valuation of the underlying investments included in the fund. Investments in publicly traded equity securities included in these strategic investment funds are valued based on the most recent sale price or official closing price reported on the exchange or over-the-counter market on which they trade, while investments in non-publicly traded equity securities are based on other factors, including but not limited to, type of the security, the size of the holding, the initial cost of the security, the price and extent of public trading in similar securities of the comparable companies, an analysis of the company's or issuer's financial statements and with respect to debt securities, the maturity and creditworthiness. As such, these fund investments have been characterized as Level 3 investments as fair values are based on significant unobservable inputs.

Share Repurchases
At Genmab’s Annual General Meeting on March 12, 2025, the Board of Directors was authorized to allow Genmab to acquire treasury shares with a total nominal value of up to 10 % of the share capital in the period until and including March 11, 2030. The purchase price for the relevant shares may not deviate by more than 10 % from the price quoted on Nasdaq Copenhagen at the time of the acquisition. Such shares may only be acquired to the extent that the Company’s total holding of treasury shares does not at any time exceed a nominal value of 10 % of the share capital. The authorization replaced existing previously provided authorizations to purchase treasury shares.
As announced on February 17, 2026, Genmab initiated a share buy-back program to honor our commitments under the RSU program. During the first six months of 2026, Genmab acquired 342,130 of its own shares under the program, representing approximately 0.5 % of share capital as of December 31, 2025. The total amount incurred to acquire the shares, including directly attributable costs, was $96 million and was recognized as a deduction to shareholders’ equity. These shares are classified as treasury shares and are presented within

As announced on March 25, 2025, Genmab initiated a share buy-back program to reduce capital and to honor our commitments under the RSU program. During the first six months of 2025, Genmab acquired 2,200,000 of its own shares under the program, representing approximately 3.3 % of share capital as of December 31, 2024. The total amount incurred to acquire the shares, including directly attributable costs, was $430 million and was recognized as a deduction to shareholders’ equity. These shares are classified as treasury shares and are presented within retained earnings on the Condensed Consolidated Balance Sheets as of June 30, 2025. As of June 30, 2025, 3,763,698 shares were available for repurchase, and 2,651,727 treasury shares were held by Genmab.
Share Capital Reduction
At Genmab’s Annual General Meeting on March 19, 2026, the decision was made to reduce the share capital with nominally DKK 1,900,000 by cancellation of 1,900,000 of the Company’s holding of shares with a nominal value of DKK 1 each. The Board of Directors resolved to complete the capital reduction on April 17, 2026, following which it was registered with the Danish Business Authority. The share capital reduction resulted in an immaterial reduction in share capital and share premium. Within retained earnings, the reclassification of treasury shares and retained earnings offset each other, resulting in no net impact on retained earnings or total equity.

In June 2026, Genmab entered into an amendment to the Credit Agreement executed in December 2025 (the “Amended Credit Agreement”), modifying the interest terms of the Term B Loans. The Amended Credit Agreement reduced the applicable interest margin from 3.00 % to 2.00 %. At the time of the Amended Credit Agreement, the nominal value on the Term B Loans was $1,950 million, which represented the initial nominal value less life to date principal repayments. Subsequent to the Amended Credit Agreement, the nominal value was $1,900 million. All other terms of the Amended Credit Agreement remain materially consistent with the Credit Agreement. The amendment did not result in derecognition of the financial liability. A modification adjustment of $23 million was made to the carrying amount of the Term B Loans, with the corresponding gain

The Term A Loans are subject to financial covenants. As of June 30, 2026, Genmab was in compliance with these covenants.
Refer to Note 4.8 in the Annual Report for further details.
Note 8 - Derivative Financial Instruments
The Company uses derivative instruments to manage its exposure to floating-rate debt indexed to 3-month Term Secured Overnight Financing Rate (SOFR). The Company has entered into interest rate swap agreements designated as cash flow hedges. These agreements are used to manage interest rate risk associated with a portion of the Company’s floating-rate debt. The Company follows established risk management policies, including the use of derivatives to hedge interest rates. The counterparties in these derivative instruments are banks which the Company considers the risk of non-performance as minimal.
If the hedge ratio for risk management purposes is no longer optimal but the risk management objective remains unchanged and the hedge continues to qualify for hedge accounting, the hedge relationship will be rebalanced by adjusting either the volume of the hedging instrument or the volume of the hedged item so that the hedge ratio aligns with the ratio used for risk management purposes. Hedge ineffectiveness is measured each reporting date and recognized immediately in profit or loss in the Condensed Consolidated Statements of Comprehensive Income. Rebalancing the hedge relationship may give rise to additional hedge ineffectiveness.

The $102 million increase in receivables and other assets was primarily due to higher DARZALEX and Kesimpta royalties achieved under our collaborations with J&J and Novartis, driven by higher net sales in the second quarter of 2026 as compared to the fourth quarter of 2025, as well as higher trade receivables resulting from increased EPKINLY sales during the same period. Receivables related to DARZALEX and Kesimpta were $886 million at June 30, 2026 compared to $822 million at December 31, 2025, an increase of $64 million or 8 %.

Note 11 - Related Parties
Genmab’s related parties are its Board of Directors, Executive Management, and close members of the family of these persons.
Genmab has not granted any loans, guarantees or other commitments to or on behalf of any of the members of the Board of Directors or members of the Executive Management.
Related party transactions include remuneration relating to the Board of Directors and the Executive Management as described in Note 5.1 in the Annual Report. There were no material related party transactions during the first six months of 2026 or 2025.
Changes to the Executive Management and the Board of Directors
Following Genmab’s Annual General Meeting on March 19, 2026, the Board of Directors is comprised of five independent board members, one non-independent board member, and three employee-elected board members. Deirdre P. Connelly (Chair), Pernille Erenbjerg (Deputy Chair), Rolf Hoffmann, Elizabeth O’Farrell, Paolo Paoletti and Anders Gersel Pedersen were re-elected to the Board of Directors for a one-year period. Mijke Zachariasse and Martin Schultz currently serve as employee-elected board members for three-year terms expiring in 2028.

Note 12 - Contingencies
Genmab is involved in pending legal proceedings arising out of the normal conduct of its business, the most significant of which are described below. These matters involve highly complex issues which are often subject to substantial uncertainties and, therefore, the probability of a loss, if any, being sustained and/or an estimate of the amount of any loss is difficult to ascertain. In cases that have been settled or adjudicated, or where quantifiable fines and penalties have been assessed and which, in each case, are not subject to appeal, or where a loss is probable and we are able to make a reasonable estimate of the loss, Genmab records the loss absorbed or makes a provision for its best estimate of the expected loss. Management has assessed the claims below on that basis and no provisions have been recorded.
Chugai Patent Infringement Complaint
In 2024, Chugai filed a lawsuit in the Tokyo District Court in Japan against AbbVie’s and Genmab’s Japanese subsidiaries asserting that their activities related to EPKINLY (epcoritamab) in Japan infringe two Japanese patents held by Chugai and claiming damages and injunctive relief. In September 2025, Chugai filed two further lawsuits in the same court, against the same parties and with similar assertions, based on two newly granted Japanese patents held by Chugai which are similar to the patents from the original lawsuit.
Genmab and AbbVie believe that all four of the patents are invalid and/or not infringed and intend to vigorously defend the claims.
AbbVie Rina-S Trade Secret Complaint
During the first quarter of 2025, AbbVie filed a complaint in the U.S. District Court for the Western District of Washington (Seattle) naming Genmab A/S; ProfoundBio U.S. Co.; ProfoundBio (Suzhou) Co., Ltd.; and former AbbVie employees as defendants. AbbVie alleges that the defendants have misappropriated AbbVie’s alleged trade secrets relating to the use of disaccharides to improve the hydrophilicity of drug-linkers in ADCs in connection with Rina-S and other ADC pipeline products of ProfoundBio. AbbVie is seeking damages and broad injunctive relief. AbbVie is not asserting or enforcing any patent rights against the defendants, and to Genmab’s knowledge, AbbVie has not pursued any development of products incorporating their alleged trade secrets. During the fourth quarter of 2025, AbbVie filed a complaint with the U.S. International Trade Commission (ITC) under Section 337 of the Tariff Act against ProfoundBio US Co.; ProfoundBio (Suzhou) Co., Ltd.; Genmab A/S; Genmab B.V.; and Genmab US, Inc., seeking to exclude certain antibody drug conjugate products from importation into the United States. The district court action was stayed during the pendency of the ITC investigation. The ITC complaint was based on allegations substantially similar to those asserted in the Washington district court action. During the second quarter of 2026, AbbVie withdrew its ITC complaint and filed an unopposed motion to terminate the investigation which will bring the ITC matter to a close. AbbVie has indicated its intention to resume its case in the district court.

We consider the applied accounting policies to be appropriate and, in our opinion, the interim report gives a true and fair view of the assets and liabilities, financial position, results of operation and cash flows of the Group.
Furthermore, we consider the Management’s Review to give a true and fair account of the development in the Group’s activities and financial affairs, results of operations and the Group’s financial position as a whole as well as a description of the significant risks and uncertainties which the Group faces, as further described in this report, our 2025 Annual Report and the Form 20-F filed with the U.S. Securities and Exchange Commission in February 2026.
