Item 2.01

Completion of Acquisition or Disposition of Assets.

As previously disclosed, XOMA Royalty Corporation (“XOMA”) entered into a share purchase agreement, dated August 3, 2025 (as amended to date, the “Purchase Agreement”), with LAVA Therapeutics N.V., a public limited liability company (naamloze vennootschap) organized under the laws of The Netherlands (the “LAVA”). In accordance with the Purchase Agreement, on August 15, 2025, XOMA commenced a tender offer (the “Offer”) to purchase all of LAVA’s issued and outstanding common shares, with a nominal value of €0.12 per share (“Shares”) for a price per Share of (i) $1.04 (the “Cash Amount”), payable subject to any applicable tax withholding and without interest, and (ii) one non-transferable contractual contingent value right (“CVR”) for each 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 described below). Capitalized terms used and not otherwise defined in this Form 8-K shall have the meanings assigned to such terms in the Offer to Purchase (as defined below).

Pursuant to the Purchase Agreement and the Amended and Restated Offer to Purchase, dated October 17, 2025 (together with any subsequent amendments or supplements thereto, the “Offer to Purchase”), and upon the terms and subject to the conditions thereof, (i) the Subsequent Offering Period expired as scheduled, one minute after 11:59 p.m. Eastern Time on Thursday, November 20, 2025 and (ii) XOMA and LAVA effectuated the Post-Offer Reorganization, which became effective on November 20, 2025. Upon completion of those transactions, each LAVA shareholder that did not tender its Shares prior to the expiration of the Subsequent Offering Period ceased to hold any Shares and will receive, pursuant to the Post-Offer Reorganization, an amount in cash and CVRs, without interest and subject to any required tax withholding, equal to the Offer Consideration multiplied by the number of Shares held by such minority shareholder immediately prior to the effective time of the Downstream Merger.

The foregoing descriptions of the Purchase Agreement, the CVR Agreement and the transactions contemplated thereby do not purport to be complete and are qualified in their entirety by reference to the Purchase Agreement and the CVR Agreement, copies of which are filed as Exhibit 2.1, Exhibit 2.2 and Exhibit 2.3 to this Current Report on Form 8-K and are incorporated by reference herein.
