Interim Report for the First Half of 2021

Highlights

| ● | The U.S. FDA accepted for Priority Review the tisotumab vedotin Biologics License Application (BLA), for patients with recurrent or metastatic cervical cancer

| ● | DARZALEX® net sales increased 52% compared to the first half of 2020 to USD 2,798 million, resulting in royalty income of DKK 2,360 million

| ● | Following a positive CHMP opinion, Janssen-Cilag International NV received European Marketing Authorization for DARZALEX SC (daratumumab and hyaluronidase-fihj) for adult patients with newly diagnosed light-chain (AL) amyloidosis

| ● | Genmab improves its 2021 financial guidance

​

“Genmab’s antibody expertise and innovation were on display during the second quarter of 2021 with the U.S. FDA’s acceptance for priority review of the BLA for tisotumab vedotin, which we are developing with Seagen, and with the approval of Janssen’s RYBREVANT™ (amivantamab-vmjw), the first regulatory approval for a product created using Genmab’s proprietary DuoBody® technology platform. The majority of Genmab’s clinical stage products are based on our DuoBody technology, and we hope that the approval of RYBREVANT is just the first validation of many of the potential for this technology to create effective treatments for patients with cancer,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

​

Financial Performance First Half of 2021

| ● | Net sales of DARZALEX by Janssen Biotech, Inc. (Janssen) were USD 2,798 million in the first half of 2021 compared to USD 1,838 million in the first half of 2020, an increase of USD 960 million, or 52%.

| ● | Royalty revenue was DKK 2,595 million in the first half of 2021 compared to DKK 1,738 million in the first half of 2020, an increase of DKK 857 million, or 49%. The increase was driven by higher net sales of DARZALEX, TEPEZZA® and Kesimpta® resulting in higher royalties.

| ● | Total revenue for the first half of 2021 was DKK 3,553 million. In addition to the royalty revenue described above, Genmab also recognized DKK 731 million of milestone revenue during the first half of 2021. Revenue for the first half of 2020 was DKK 6,343 million and included the one-time upfront payment of DKK 4,398 million recognized as license revenue from AbbVie Inc. (AbbVie) pursuant to our collaboration announced in June 2020.

| ● | Operating expenses were DKK 2,234 million in the first half of 2021 compared to DKK 1,775 million in the first half of 2020. The increase of DKK 459 million, or 26%, was driven by the continued advancement of multiple pipeline projects, and the increase in new employees to support the expansion of our product pipeline and building our commercialization capabilities and broader organizational infrastructure.

| ● | Operating result was DKK 1,319 million in the first half of 2021 compared to DKK 4,568 million in the first half of 2020. The decrease of DKK 3,249 million, or 71%, was driven by lower revenue as a result of the non-recurring license revenue in 2020 and increased operating expenses.

​

Outlook

Genmab is improving its 2021 financial guidance published on February 23, 2021, driven primarily by increased royalty revenue related to the net sales of DARZALEX.

Interim Report for the First Half of 2021

OUTLOOK

​

​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Revised | ​ | Previous | ​
(DKK million) |  | Guidance |  | Guidance |
Revenue |  | 7,300 - 7,900 |  | 6,800 - 7,500 |

​
Genmab is improving its 2021 financial guidance published on February 23, 2021, driven primarily by increased royalty revenue related to the net sales of DARZALEX.

​

Revenue

Genmab expects its 2021 revenue to be in the range of DKK 7,300–7,900 million, an increase compared to previous guidance of DKK 6,800-7,500 million, driven primarily by the continued strong growth of DARZALEX net sales. Genmab’s projected revenue for 2021 primarily consists of DARZALEX royalties of DKK 5,300–5,700 million. Such royalties are based on Genmab’s revised estimate of DARZALEX 2021 net sales of USD 5.6–5.9 billion compared to Genmab’s previous estimate of USD 5.2-5.6 billion. Since the second quarter of 2020, Janssen has reduced its royalty payments to Genmab by what it claims to be Genmab’s share of Janssen’s royalty payments to Halozyme in connection with subcutaneous (SC) sales. Given the ongoing arbitration, Genmab has reflected this as a reduction to estimated 2021 revenue. The remainder of Genmab’s revenue consists of royalties from TEPEZZA and Kesimpta, reimbursement revenue, milestones for epcoritamab and daratumumab, and other milestones.

​

Operating Expenses

Genmab anticipates its 2021 operating expenses to be in the range of DKK 5,500–5,800 million, which is in line with previous guidance. Operating expenses continue to be driven by the advancement of Genmab’s clinical programs, continued investment in research and development, as well as building Genmab’s commercial organization and broader organizational infrastructure.

​

Operating Result

Genmab now expects its 2021 operating result to be in the range of DKK 1,500–2,400 million, an increase compared to previous guidance of DKK 1,000-2,000 million, driven primarily by the increase in royalty revenue related to the net sales of DARZALEX.

​

Outlook: Risks and Assumptions

In addition to factors already mentioned, the estimates above are subject to change due to numerous reasons, including but not limited to the achievement of certain milestones associated with Genmab’s collaboration agreements; ongoing binding arbitration of two matters under Genmab’s license agreement with Janssen relating to daratumumab; the timing and variation of development activities (including activities carried out by Genmab’s collaboration partners) and related income and costs; DARZALEX, Kesimpta, TEPEZZA and RYBREVANT net sales and royalties paid to Genmab; and currency exchange rates (the 2021 guidance assumes a USD/DKK exchange rate of 6.0). The financial guidance assumes that no significant new agreements are entered into during the remainder of 2021 that could materially affect the results. Refer to the section “Significant Risks and Uncertainties” in this interim report. Additionally, the COVID-19 pandemic could potentially have a material adverse impact on Genmab’s business and financial performance, including clinical trials, projected regulatory approval timelines, supply chain and revenues, and cause Genmab’s actual results to differ materially from 2021 Guidance and Key 2021 Priorities in this interim report.

Interim Report for the First Half of 2021

Genmab and developed and marketed by Genmab’s collaboration partners. The longer the pandemic continues, the more severe the impacts described below will be on Genmab’s business. The extent, length and consequences of the pandemic are uncertain and impossible to predict. Genmab has established a COVID-19 response team, led by the CEO, that closely monitors the evolving situation, develops and implements precautionary measures to help limit the impact of COVID-19 at the workplace and on our communities, and ensures business continuity. Genmab is also actively monitoring the potential impact on Key 2021 Priorities and assessing the situation on an ongoing basis in close contact with clinical trial sites, physicians and contract research organizations (CROs) to evaluate the impact and challenges posed by the COVID-19 situation and manage them accordingly. The full extent and nature of the impact of the COVID-19 pandemic and related containment measures on Genmab’s business and financial performance is uncertain as the situation continues to evolve. The factors discussed above, as well as other factors which are currently unforeseeable, may result in further and other unforeseen material adverse impacts on Genmab’s business and financial performance, including on the net sales of DARZALEX, Kesimpta, TEPEZZA and RYBREVANT, by Genmab’s partners and on Genmab’s royalty and milestone revenue therefrom.

Tisotumab vedotin – A Next Generation Therapeutic

| ● | An investigational antibody-drug conjugate (ADC) directed to tissue factor (TF), a protein highly prevalent in solid tumors, including cervical cancer, which is associated with poor prognosis

| ● | Based on data from the innovaTV 204 (NCT03438396) Phase 2 single-arm clinical study evaluating tisotumab vedotin as monotherapy in patients with previously treated recurrent or metastatic cervical cancer, a BLA was submitted to the U.S. Food and Drug Administration (U.S. FDA); potential Japanese New Drug Application (JNDA) filing timeline postponed to include Phase 3 innovaTV 301 (NCT04697628) data

| ● | U.S. FDA accepted the BLA with Priority Review; under the Prescription Drug User Fee Act (PDUFA), the U.S. FDA set a target action date of Oct 10, 2021

| ● | Phase 3 study in recurrent or metastatic cervical cancer and multiple Phase 2 clinical studies in other solid tumors ongoing

| ● | Developed in collaboration with Seagen

​

Tisotumab vedotin is an ADC targeted to TF, a protein involved in tumor signaling and angiogenesis. It is composed of Genmab’s fully human monoclonal antibody specific for tissue factor and Seagen’s ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (MMAE) to the antibody and releases it upon internalization, inducing target cell death. Based on its high expression on many solid tumors and its rapid internalization, TF is a suitable target for an ADC approach. Genmab used technology licensed from Medarex to generate the TF antibody forming part of tisotumab vedotin. Tisotumab vedotin is in clinical development for solid tumors. Tisotumab vedotin is being co-developed by Genmab and Seagen, under an agreement in which the companies share all costs and profits for the product on a 50:50 basis. Under a joint commercialization agreement, Genmab will co-

Interim Report for the First Half of 2021

FINANCIAL REVIEW

The interim report is prepared on a consolidated basis for the Genmab group. The financial statements are published in Danish Kroner (DKK).

Revenue

Genmab’s revenue was DKK 3,553 million for the first half of 2021 compared to DKK 6,343 million for the first half of 2020. The decrease of DKK 2,790 million, or 44%, was primarily driven by the one-time upfront payment of DKK 4,398 million recognized as license revenue from AbbVie pursuant to our collaboration announced in June 2020, partly offset by higher DARZALEX royalties as well as milestone revenue from various collaboration partners.

​

​

​ | ​ | ​ | ​ | ​
(DKK million) |  | H1 2021 |  | H1 2020
Royalties |  | 2,595 |  | 1,738
Reimbursement revenue |  | 227 |  | 175
Milestone revenue |  | 731 |  | 32
License revenue | ​ | — | ​ | 4,398
Total revenue |  | 3,553 |  | 6,343

​

Royalties

Royalty revenue amounted to DKK 2,595 million in the first half of 2021 compared to DKK 1,738 million in the first half of 2020. The increase of DKK 857 million, or 49%, was primarily driven by higher DARZALEX royalties achieved under our daratumumab collaboration with Janssen.

​

Net sales of DARZALEX by Janssen were USD 2,798 million in the first half of 2021 compared to USD 1,838 million in the first half of 2020. The increase of USD 960 million, or 52%, was driven by the continued strong uptake of DARZALEX. Royalty revenue on net sales of DARZALEX was DKK 2,360 million in the first half of 2021 compared to DKK 1,652 million in the first half of 2020, an increase of DKK 708 million. The percentage increase in royalties of 43% is lower than the percentage increase in the underlying net sales primarily due to the lower exchange rate between the USD and DKK in the first half of 2021 compared to the first half of 2020 and the impact of Janssen’s continued withholding of a portion of the royalty payments owed to Genmab. Since the second quarter of 2020, Janssen has reduced its quarterly royalty payments to Genmab by what Janssen claims to be Genmab’s share of Janssen’s royalty payments to Halozyme in connection with SC sales. Given the ongoing arbitration, Genmab has reflected this reduction in its royalty revenues each quarter. The impact to royalties in the first half of 2021 is estimated to be DKK 146 million.

​

TEPEZZA (teprotumumab-trbw) was launched by Horizon in the first quarter of 2020. In December 2020, Horizon announced that there was a supply disruption related to the production of TEPEZZA due to U.S. government-mandated COVID-19 vaccine production requirements. Subsequently, in March 2021, Horizon announced its plans to resupply the market beginning in April 2021. Royalties, which are based on net sales, amounted to DKK 162 million during the first half of 2021 compared to DKK 77 million during the first half of 2020. The increase of DKK 85 million was driven by the strong uptake of TEPEZZA.

​

Novartis was granted U.S. FDA approval for Kesimpta (ofatumumab) in relapsing multiple sclerosis and Genmab started recognizing royalties on net sales of Kesimpta during the third quarter of 2020.

Royalties, which are based on net sales, amounted to DKK 72 million for the first half of 2021.

​

Janssen was granted U.S. FDA approval for RYBREVANT (amivantamab-vmjw) (ofatumumab), a fully human bispecific antibody that targets EGFR and cMet, and Genmab started recognizing royalties on net sales of RYBREVANT during the second quarter of 2021. Royalties for the quarter were not material.

​

Interim Report for the First Half of 2021

​

Royalty revenue fluctuations from period to period are due primarily to the level of product net sales as well as foreign currency exchange rates.

​

Reimbursement Revenue

Reimbursement revenue amounted to DKK 227 million in the first half of 2021 compared to DKK 175 million in the first half of 2020. The increase of DKK 52 million, or 30%, was primarily driven by higher activities under our collaboration agreement with BioNTech for DuoBody-PD-L1x4-1BB.

​

Milestone Revenue

Milestone revenue was DKK 731 million in the first half of 2021 compared to DKK 32 million in the first half of 2020, an increase of DKK 699 million, primarily driven by the following:

​

| ● | AbbVie milestone of DKK 245 million (USD 40 million) triggered by the first patient dosed in the Phase 3 study of epcoritamab,

| ● | DARZALEX FASPRO milestone of DKK 184 million (USD 30 million) driven by the first commercial sale in the U.S. for patients with newly diagnosed AL amyloidosis,

| ● | Janssen DuoBody milestone of DKK 152 million (USD 25 million) driven by U.S. FDA approval for RYBREVANT, and

| ● | DARZALEX SC milestone of DKK 125 million (USD 20 million) driven by the first commercial sale in the EU for patients with newly diagnosed AL amyloidosis.

​

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.

​

License Revenue

There was no license fee income during the first half of 2021. License revenue was DKK 4,398 million during the first half of 2020, which was driven by the delivery of licenses for three programs under the AbbVie collaboration.

​

Refer to Financial Statement Note 2 in this interim report for further details about revenue.

​

Research and Development Costs

Research and development costs amounted to DKK 1,769 million in the first half of 2021 compared to DKK 1,490 million in the first half of 2020. The increase of DKK 279 million, or 19%, was driven by the continued advancement of epcoritamab and DuoBody-PD-L1x4-1BB under our collaborations with AbbVie and BioNTech, respectively, and the increase in new employees to support the expansion of our product pipeline. During the first half of 2021, Genmab recorded DKK 331 million as compared to DKK 45 million during the first half of 2020 as a reduction to research and development costs for reimbursement related to the collaboration agreement with AbbVie. Pursuant to this agreement, which was entered into during the second quarter of 2020, Genmab and AbbVie share equally in both research and development costs.

​

Research and development costs accounted for 79% of total operating expenses in the first half of 2021 compared to 84% in the first half of 2020.

​

General and Administrative Expenses

General and administrative expenses were DKK 465 million in the first half of 2021 compared to DKK 285 million in the first half of 2020. The increase of DKK 180 million, or 63%, was driven by the increase in new employees as Genmab builds its commercialization capabilities and broader organizational infrastructure.

Net financial items for the first half of 2021 were a gain of DKK 527 million compared to a gain of DKK 114 million in the first half of 2020. The increase of DKK 413 million was primarily driven by the strengthening of the USD against the DKK on Genmab’s U.S. denominated portfolio and cash holdings, partly offset by losses on marketable securities driven by movements in interest rates in the United States and Europe. Refer to Financial Statement Note 4 in this interim report for further details about the net financial items.

​

Corporate Tax

Corporate tax expense for the first half of 2021 was DKK 444 million compared to DKK 1,035 million for the first half of 2020. The decrease in corporate tax expense is primarily the result of Genmab’s lower net result before tax. The effective tax rate in the first half of 2021 was 24% compared to 22% in the first half of 2020.

​

Net Result

Net result for the first half of 2021 was DKK 1,402 million compared to DKK 3,647 million in the first half of 2020. The decrease was driven by the items described above.

Cash Position (DKK million) |  | June 30, 2021 |  | December 31, 2020
Marketable securities |  | 8,398 |  | 8,819
Cash and cash equivalents |  | 9,477 |  | 7,260
Cash position |  | 17,875 |  | 16,079

​

As of June 30, 2021, cash, cash equivalents and marketable securities (cash position) amounted to DKK 17,875 million, an increase of DKK 1,796 million, or 11%, from the beginning of 2021. The increase was primarily driven by Genmab’s operating result of DKK 1,319 million, net exchange rate gains of DKK 573 million due to the strengthening of the USD, and proceeds received of DKK 438 million from the sale of a portion of Genmab’s CureVac shares during the first half of 2021, partly offset by cash payments for the purchase of treasury shares of DKK 437 million during the first half of 2021. Refer to Financial Statement Note 3 in this interim report for further details about the sale of CureVac shares. Refer to Financial Statement Note 5 in this interim report for further details about the purchase of treasury shares.

​

As of June 30, 2021, Genmab’s USD denominated cash, cash equivalents and marketable securities represents 85% of Genmab’s cash position compared to 83% as of December 31, 2020.

​

Cash and cash equivalents included short-term marketable securities of DKK 2,569 million at the end of June 2021, compared to DKK 2,206 million at the end of December 2020. In accordance with our accounting policy, securities purchased with a maturity of less than three months at the date of acquisition are classified as cash and cash equivalents. Refer to Financial Statement Note 3 in this interim report for further details about our marketable securities.

Interim Report for the First Half of 2021

Cash Flow

​

​ | ​ | ​ | ​ | ​
Cash Flow (DKK million) |  | H1 2021 |  | H1 2020
Cash provided by operating activities |  | 1,540 |  | 2,153
Cash provided by investing activities |  | 966 |  | 928
Cash (used in) provided by financing activities |  | (460) |  | 19

​

Net cash provided by operating activities is primarily related to our operating result, changes in operating assets and liabilities, reversal of net financial items, and adjustments related to non-cash transactions. In the first half of 2021, as compared to the first half of 2020, the primary driver of lower cash provided by operating activities was due to decreased changes in operating assets and liabilities related to non-recurring DARZALEX milestones of DKK 1.7 billion achieved in the fourth quarter of 2019 that were received in 2020.

​

The change in cash provided by investing activities primarily reflects differences between the proceeds received from sale and maturity of our investments and amounts invested, and the investment in tangible assets. Sales and maturities of marketable securities exceeded purchases in both periods, but to a greater extent in the first half of 2020. For the first half of 2021, investing activities also includes the proceeds from the sale of CureVac shares of DKK 438 million.

​

Net cash used in financing activities is primarily related to the exercise of warrants, purchase of treasury shares, lease payments, and payment of withholding taxes on behalf of employees on net settled Restricted Stock Units (RSUs). In the first half of 2021, the primary driver of the cash used in financing activities was related to cash payments for the purchase of treasury shares of DKK 437 million.

​

Balance Sheet

As of June 30, 2021, total assets were DKK 22,483 million compared to DKK 21,143 million on December 31, 2020. As of June 30, 2021, assets are mainly comprised of a cash position of DKK 17,875 million and current receivables of DKK 2,429 million. The current receivables consist primarily of amounts related to royalties and milestones from our collaboration agreements.

​

As of June 30, 2021, total liabilities were DKK 2,231 million compared to DKK 2,022 million on December 31, 2020. The increase in total liabilities of DKK 209 million, or 10%, was primarily driven by corporate tax payable of DKK 186 million and an increase in lease liabilities of DKK 124 million related to the commencement of leases in Japan and the United States.

​

Shareholders’ equity as of June 30, 2021 was DKK 20,252 million compared to DKK 19,121 million on December 31, 2020. The increase of DKK 1,131 million, or 6%, was primarily driven by Genmab’s net result and the issuance of shares related to the share-based compensation plans, partly offset by the purchase of treasury shares. Genmab’s equity ratio remained unchanged at 90% as of June 30, 2021 compared to December 31, 2020.

​

As of June 30, 2021, the total number of employees was 1,029 compared to 636 employees as of June 30, 2020. The increase in employees was primarily driven by the expansion and acceleration of our pipeline, as well as investment in commercialization capabilities and broader organizational infrastructure.

Interim Report for the First Half of 2021

Legal Matter – Janssen Binding Arbitration

In September 2020, Genmab commenced binding arbitration of two matters arising under its license agreement with Janssen Biotech, Inc. (Janssen) relating to daratumumab. Under the license agreement, Genmab is, among other things, entitled to royalties from Janssen on sales of daratumumab (marketed as DARZALEX for intravenous administration and as DARZALEX FASPRO in the United States and as DARZALEX SC in Europe for SC administration). The arbitration first is to settle whether Genmab is required to share in Janssen’s royalty payments to Halozyme Therapeutics, Inc. for the Halozyme enzyme technology used in the SC formulation of daratumumab. The royalties Janssen pays to Halozyme represent a mid-single digit percentage rate of SC daratumumab sales. Janssen has started reducing its royalty payments to Genmab by what it claims to be Genmab’s share of Janssen’s royalty payments to Halozyme beginning in the second quarter of 2020 and has continued to do so through June 30, 2021. Given the ongoing arbitration, Genmab has reflected this reduction in its royalty revenues each quarter. The impact to the first half of 2021 royalties is estimated to be DKK 146 million. The impact to the first half of 2020 royalties is not material. The arbitration is also to settle whether Janssen’s obligation to pay royalties on sales of licensed product extends, in each applicable country, until the expiration or invalidation of the last-to-expire relevant Genmab-owned patent or the last-to-expire relevant Janssen-owned patent covering the product, as further defined and described in the license agreement.

Interim Report for the First Half of 2021

NOTES TO THE FINANCIAL STATEMENTS

Note 1 – Basis of Presentation

Accounting Policies

These interim statements of the Genmab group (Genmab or the Company) have been prepared in accordance with IAS 34 as issued by the International Accounting Standards Board (IASB) and in accordance with IAS 34 as endorsed by the EU and additional Danish disclosure requirements for interim reports of listed companies. The interim report has not been reviewed or audited 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 2020 Annual Report (Annual Report). A number of new or amended standards became applicable for the current reporting period. Genmab was not required to change its accounting policies as a result of adopting these standards. These interim financial statements should be read in conjunction with the Annual Report.

​

Management Judgments and Estimates under IFRS

In preparing interim reports, certain provisions under IFRS require management to make judgments (various accounting estimates and assumptions) which may significantly impact the group’s financial statements. For a description of significant judgments and estimates, refer to Note 1.3 in the Annual Report.

Information about Geographical Areas

Interim Report for the First Half of 2021

Note 2 – Revenue

Genmab enters into license and collaboration agreements that are within the scope of IFRS 15, under which it licenses certain rights to its product candidates to third parties and also may participate in the development of the product candidates. The terms of these arrangements typically include payment to Genmab of one or more of the following: non-refundable, upfront license fees; exclusive designation fees; annual license maintenance fees; additional target fees; development, regulatory and commercial milestone payments; reimbursements for research and development services; and royalties on net sales of licensed products. Each of these payments results in revenue from contracts with customers.

In September 2020, Genmab commenced binding arbitration of two matters arising under its license agreement with Janssen Biotech, Inc. (Janssen) relating to daratumumab. Under the license agreement, Genmab is, among other things, entitled to royalties from Janssen on sales of daratumumab (marketed as DARZALEX for intravenous administration and as DARZALEX FASPRO in the United States and as DARZALEX SC in Europe for SC administration). The arbitration first is to settle whether Genmab is required to share in Janssen’s royalty payments to Halozyme Therapeutics, Inc. for the Halozyme enzyme technology used in the SC formulation of daratumumab. The royalties Janssen pays to Halozyme represent a mid-single digit percentage rate of SC daratumumab sales. Janssen has started reducing its royalty payments to Genmab by what it claims to be Genmab’s share of Janssen’s royalty payments to Halozyme beginning in the second quarter of 2020 and has continued to do so through June 30, 2021. Given the ongoing arbitration, Genmab has reflected this reduction in its royalty revenues each quarter. The impact to the first half of 2021 royalties is estimated to be DKK 146 million. The impact to the first half of 2020 royalties is not material. The arbitration is also to settle whether Janssen’s obligation to pay royalties on sales of licensed product extends, in each applicable country, until the expiration or invalidation of the last-to-expire relevant Genmab-owned patent or the last-to-expire relevant Janssen-owned patent covering the product, as further defined and described in the license agreement.

​
The table below summarizes Genmab’s revenue by type and collaboration partner under Genmab’s agreements. This information provides the reader additional information regarding the nature, amount, timing and uncertainty of Genmab’s revenue and how cash flows might be affected by economic factors.

Interim Report for the First Half of 2021

AbbVie Collaboration Agreement

On June 10, 2020, Genmab entered into a broad collaboration agreement to jointly develop and commercialize epcoritamab (DuoBody-CD3xCD20), DuoHexaBody-CD37 and DuoBody-CD3x5T4 and a discovery research collaboration for future differentiated antibody therapeutics for cancer. Under the terms of the agreement, Genmab received a USD 750 million (DKK 4,911 million) upfront payment in July 2020. Genmab recognized DKK 4,398 million as license revenue during the first half of 2020 driven by the delivery of licenses for the three programs described above. Genmab recorded DKK 513 million as deferred revenue related to co-development activities for product concepts and is expected to be recognized as revenue activities are performed, which is estimated to be over a seven-year period. No revenue has been recognized in the first half of 2021 or 2020 as co-development activities for product concepts have not yet commenced.

Note 5 – Share-Based Instruments

Restricted Stock Unit Program

Genmab A/S established an RSU program as an incentive for all the Genmab group’s employees, members of the Executive Management, and members of the Board of Directors.

​

For details of the RSU program prior to changes in 2021, refer to Note 4.6 in the Annual Report.

​

In February 2021, the RSU program was amended (the “2021 RSU Program”). Under the terms of the 2021 RSU Program, the Board may decide, in its sole discretion, to accelerate the vesting of the RSUs held by a participant, or accelerate the vesting of the RSUs and make a cash settlement in case of (1) a change of control event as defined in the 2021 RSU Program, if a participant’s employment terms are materially changed to his or her detriment during the 12-month period following the change in control event, or if the participant, who is a member of the Board, is replaced by a new board member or such participant's seat on the Board is eliminated due to a reduction in the number of board members, or (2) certain other extraordinary transactions as described in the 2021 RSU Program.

​

Under the terms of the 2021 RSU Program, in the event an RSU holder separates from the Company under circumstances in which the RSU holder is considered a “bad-leaver,” such as being dismissed for cause or during the employment probationary period, unvested RSU will be forfeited. RSU holders may maintain a pro rata portion of unvested RSUs if they separate from the Company under circumstances where they are considered “good-leavers,” such as dismissal without cause or termination of employment due to the Company’s material breach of the RSU holder’s employment terms, or if the participant is a member of the Board, if the membership of the Board ceases for any other reason than as a result of the participants death. All unvested RSUs will be forfeited in the event of termination of employment due to the RSU holder’s death.

​

During the first half of 2021, 159,567 RSUs were granted with a weighted average fair value of DKK 2,149.55 per RSU. During the first half of 2020, 22,672 RSUs were granted with a weighted average fair value of DKK 1,491.16 per RSU.

​

During the first half of 2021, 49,012 RSUs vested, compared to 39,438 RSUs during the first half of 2020. Genmab settles RSUs using shares issued from treasury stock. A portion of the settlement is withheld to satisfy individual statutory tax withholding obligations in certain jurisdictions which remain in Genmab’s treasury share account.

​

Warrant Program

Genmab A/S established warrant programs as an incentive for all the Genmab group’s employees, and members of the Executive Management.

For details of the warrant programs prior to changes in 2021, refer to Note 4.6 in the Annual Report.

​

In February 2021, the Warrant Program was amended (the “2021 Warrant Program”). Under the terms of the 2021 Warrant Program, the Board may decide, in its sole discretion, to accelerate the vesting of the warrants held by a warrant holder in case of (1) a change of control event as defined in the 2021 Warrant Program, if a warrant holder’s employment terms are materially changed to his or her detriment during the 12-month period following a change in control event, or (2) certain other extraordinary transactions as described in the 2021 Warrant Program.

Interim Report for the First Half of 2021

Under the 2021 Warrant Program, if a warrant holder separates from the Company under circumstances in which the warrant holder is considered a “bad-leaver,” such as being dismissed for cause or during the employment probationary period, unvested warrants will be forfeited. Warrant holders may maintain a pro rata portion of unvested warrants if they separate from the Company under circumstances where they are considered “good-leavers,” such as dismissal without cause or termination of employment due to the Company’s material breach of the warrant holder’s employment terms. All unvested warrants will be forfeited in the event of termination of employment due to the warrant holder’s death.

During the first half of 2021, 147,568 warrants were granted to Genmab employees with a weighted average exercise price of DKK 2,189.21 per warrant and a weighted average Black-Scholes fair market value of DKK 683.79 per warrant. During the first half of 2020, 49,323 warrants were granted to Genmab employees with a weighted average exercise price of DKK 1,548.22 per warrant and a weighted average Black-Scholes fair market value of DKK 465.70 per warrant.

​

During the first half of 2021, 74,992 warrants were exercised with a weighted average exercise price on date of grant of DKK 606.22 with proceeds to Genmab of DKK 46 million. The warrants exercised increased share capital accordingly and corresponded to approximately 0.11% of share capital. During the first half of 2020, 272,078 warrants were exercised with a weighted average exercise price on date of grant of DKK 261.06 with proceeds to Genmab of DKK 71 million. The warrants exercised increased share capital accordingly and corresponded to approximately 0.42% of share capital.

Share-based compensation expense

Share-based compensation expenses related to Genmab RSU and warrant programs for the first half of 2021 totaled DKK 142 million compared to DKK 98 million for the first half of 2020.

​
Share repurchases

In general, Genmab intends to purchase its own shares in order to cover a portion of the obligations in relation to RSUs. Authorization to purchase Genmab shares up to a nominal value of DKK 500,000 (500,000 shares) was given by the shareholders at the annual general meeting in March 2016. As of December 31, 2020, a total of 225,000 shares, with a nominal value of DKK 225,000, had been repurchased under the March 2016 authorization. The March 2016 authorization expired in March 2021. Additionally, in March 2019, Genmab shareholders authorized the repurchase up to an additional nominal value of DKK 500,000 (500,000 shares). A portion of the shares that may be repurchased under this authorization may be used to cover Genmab’s obligations in relation to the RSUs. Moreover, in April 2021, Genmab shareholders authorized us to repurchase up to an additional nominal value of DKK 500,000 (500,000 shares) to cover obligations under our share-based remuneration programs.

​

As announced on February 23, 2021, Genmab initiated a share buy-back program. During the first half of 2021, Genmab acquired 200,000 of its own shares, representing approximately 0.3% of share capital. The total amount paid to acquire the shares, including directly attributable costs, was DKK 447 million and has been recognized as a deduction to shareholders’ equity. These shares are classified as treasury shares and are presented within retained earnings on the balance sheet as of June 30, 2021. There were no share repurchases during the first half of 2020.

​

As of June 30, 2021, 299,206 treasury shares were held by Genmab to cover the obligations in relation to the RSU program and to mitigate the dilutive effect of share capital increases resulting from future exercises of warrants.
