Introductory Note

As previously disclosed by LAVA Therapeutics N.V., a Dutch public limited liability company (naamloze vennootschap) (the “Company”), on August 3, 2025, the Company entered into a Purchase Agreement (the “Purchase Agreement”) with XOMA Royalty Corporation, a Nevada corporation (“Buyer”), as amended by that certain Amendment to the Purchase Agreement dated October 17, 2025 (the “Amendment”), to purchase all of the issued and outstanding common shares, par value €0.12 per share, of the Company (“Shares”) at a purchase price of $1.04 per Share plus (ii) one contingent value right (“CVR”) per Share, which shall represent the right to receive potential payments, in cash, described in, and subject to and in accordance with the terms and conditions of, the CVR Agreement (as defined and further described below), payable subject to any applicable tax withholding and without interest (together with the Cash Amount, the “Offer Consideration”), all upon the terms and subject to the conditions as set forth in the Amended and Restated Offer to Purchase, dated October 17, 2025 (as may be amended or supplemented from time to time, the “Offer to Purchase”) and in the related Letter of Transmittal (the “Letter of Transmittal,” together with the Offer to Purchase and other related materials, as each may be amended or supplemented from time, the “Offer”).

The Offer, as extended, expired one minute after 11:59 p.m. Eastern Time on November 12, 2025 (the “Expiration Time”), at which time all conditions to the Offer were satisfied or waived. Broadridge Corporate Issuer Solutions, LLC, the depositary for the Offer (the “Depositary”), advised Buyer that, as of the Expiration Time, 22,877,463 Shares, representing approximately 87% of the issued and outstanding Shares, were validly tendered pursuant to the Offer and not properly withdrawn. The number of Shares tendered satisfied the Minimum Condition (as defined in the Purchase Agreement) for the Offer. On November 13, 2025, Buyer accepted for payment all such Shares validly tendered and not properly withdrawn pursuant to the Offer prior to the Expiration Time and promptly thereafter paid (by delivery of funds to the Depositary) (the “Closing”) for all such Shares.

Item 2.01

Completion of Acquisition or Disposition of Assets.

Following the Expiration Time, in accordance with the Purchase Agreement, Buyer commenced a subsequent offering period (the “Subsequent Offering Period”) in accordance with Rule 14d-11 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on November 13, 2025. Shares validly tendered during the Subsequent Offering Period were immediately accepted and promptly paid for by Buyer pursuant to the terms of the Offer. The Subsequent Offering Period expired one minute after 11:59 p.m. Eastern Time on November 20, 2025. The Depositary informed Buyer that, as of the expiration of the Subsequent Offering Period, 23,956,708 Shares, collectively representing approximately 91.1% of the total outstanding Shares, were validly tendered pursuant to the Offer (including a total of 1,079,245 Shares, collectively representing approximately 4.2% of the total outstanding Shares tendered during the Subsequent Offering Period).

Tax information relevant to the Company’s shareholders that did not tender their Shares in the Offer or during the Subsequent Offering Period and who are subject to the Cancellation is provided in the section entitled “Certain U.S Federal Income and Dutch Tax Consequences of the Offer and the Post-Offer Reorganization” of the Offer to Purchase and is incorporated by reference herein. This information is relevant to the filing of such shareholders’ tax returns and should be reviewed with their tax advisors.

The foregoing description of the Purchase Agreement is only a summary and is qualified in its entirety by reference to the full text of the Purchase Agreement and Amendment thereto, which are incorporated by reference herein from Exhibit 2.1 to the Current Reports on Form 8-K filed by the Company with the Securities and Exchange Commission on August 3, 2025 and October 17, 2025, respectively.
