On December 9, 2025, Merus N.V., a public limited liability company (*naamloze vennootschap*) organized under the laws of the Netherlands ("Merus" or the "Company"), held an extraordinary general meeting of its shareholders (the "EGM") to vote on the proposals described in the definitive proxy statement of the Company prepared in connection with the Transaction Agreement (as defined below) and filed with the U.S. Securities and Exchange Commission (the "SEC") on November 12, 2025.

As contemplated by the transaction agreement, dated September 29, 2025 (as it may be amended, supplemented or otherwise modified from time to time, the "Transaction Agreement"), by and among the Company, Genmab A/S, a public limited liability company (*Aktieselskab*) organized under the laws of Denmark ("Genmab"), and Genmab Holding II B.V., a private limited liability company (*besloten vennootschap met beperkte aansprakelijkheid*) organized under the laws of The Netherlands ("Purchaser") and a wholly owned subsidiary of Genmab, Purchaser has made an offer to purchase all of the issued and outstanding common shares, nominal value €0.09 per share, of the Company (the "Common Shares"), in exchange for $97.00 per Common Share in cash (the "Offer Consideration"), without interest and subject to any applicable tax withholding, on the terms and subject to the conditions set forth in the offer to purchase, dated October 21, 2025 (as it may be amended, supplemented or otherwise modified from time to time, the "Offer to Purchase"), and in the related letter of transmittal (as it may be amended or supplemented from time to time, the "Letter of Transmittal" and, together with the Offer to Purchase, the "Offer").

Unless the Offer is earlier terminated, the Offer will expire at 5:00 p.m., New York City time, on December 11, 2025 or, if the Offer is extended pursuant to and in accordance with the terms of the Transaction Agreement, the date and time to which the Offer has been so extended (the "Initial Expiration Time", or such later expiration date and time to which the Offer has been so extended, the "Expiration Time"). If the conditions to the consummation of the Offer are satisfied or waived (to the extent permitted by the Transaction Agreement and applicable law), on the first business day after the date at which the Offer expires, Purchaser will commence a subsequent offering period (the "Subsequent Offering Period") for a period of at least ten (10) business days to purchase additional Common Shares. Pursuant to the Subsequent Offering Period, Purchaser will offer to purchase such additional Common Shares validly tendered during such Subsequent Offering Period at the Offer Consideration, without interest and subject to any applicable tax withholding (the "Subsequent Closing", and the final date on which Common Shares tendered during the Subsequent Offering Period are accepted for payment and paid for, the "Subsequent Closing Date").

As of the close of business on November 11, 2025, the record date for the EGM, there were 75,847,175 Common Shares issued and outstanding and entitled to vote at the EGM. A total of 53,764,929 Common Shares were present or represented by proxy at the EGM, representing approximately 70.88% of the Company's issued and outstanding Common Shares entitled to vote, and thus a quorum was present. The following are the voting results for the proposals considered and voted upon at the EGM:

*Proposal 1* **-** Approval of Back-End Transactions (as defined in the Transaction Agreement), which comprises two separate voting items:

*Proposal 1a* **-** Subject to certain conditions and provided that a certain Dutch tax ruling is obtained on or prior to the Subsequent Closing Date, approval of a resolution (1) to enter into a statutory merger (*juridische fusie*) under Dutch law pursuant to which the Company, as disappearing company, will merge with and into Merus Merger B.V. ("New TopCo"), as surviving company (the "Back-End Merger"), and (2) to approve, within the meaning of Section 2:107a of the Dutch Civil Code and to the extent required by applicable law, such Back-End Merger and the subsequent cancellation of all class A shares in the capital

------

of New TopCo with repayment and distribution by New TopCo of an amount per class A share so cancelled equal to the Offer Consideration, without interest and subject to any applicable withholding taxes:
