XOMA Royalty Announces Closing of Transactions to Acquire LAVA Therapeutics N.V.

EMERYVILLE, Calif., Nov. 21, 2025 (GLOBE NEWSWIRE) — XOMA Royalty Corporation (“XOMA Royalty”) (Nasdaq: XOMA) today announced it has successfully completed its previously announced acquisition of all the outstanding common shares of LAVA Therapeutics N.V. (“LAVA”) (NASDAQ: LVTX) with a nominal value of €0.12 per share (“Shares”).  LAVA shareholders received $1.04 in cash per Share and a non-transferrable contingent value right (“CVR”) per Share representing the right to receive certain cash payments, including (A) the right to receive, among other things, 75% of any net proceeds related to LAVA’s two partnered assets plus 75% of any net proceeds from any out license or sale of LAVA’s unpartnered programs plus (B) the right to receive up to approximately $0.23 per CVR depending on the final determination after closing of certain potential liabilities.

“The acquisition of LAVA Therapeutics reinforces XOMA’s philosophy of ‘strength in numbers’, adding two early-stage bispecific antibodies in collaboration with well-established oncology partners, Johnson and Johnson and Pfizer,” stated Owen Hughes, Chief Executive Officer of XOMA Royalty.  “The combination of future milestones and royalties from the LAVA programs has the potential to drive significant value creation for the LAVA CVR holders and XOMA Royalty over time.”

The initial offer period and subsequent offer period expired one minute after 11:59 p.m. Eastern Time on Wednesday, November 12, 2025, and one minute after 11:59 p.m. Eastern Time on Thursday, November 20, 2025 (the “Final Expiration Date”), respectively.  As of the Final Expiration Date, a total of 23,956,708 Shares were validly tendered, and not validly withdrawn, representing approximately 91.1% of the outstanding Shares as of the Final Expiration Date. 

Following the acceptance for payment of all Shares tendered in the subsequent offering period, LAVA consummated a corporate reorganization resulting in XOMA Royalty acquiring 100% of the shares in LAVA’s successor and all then-remaining LAVA shareholders (other than XOMA Royalty) receiving the same cash and CVR consideration per share as is provided in the tender offer, subject to applicable withholding taxes.  Prior to the opening of trading on November 21, 2025, public trading of the Shares was suspended, and LAVA intends promptly to cause such Shares to be delisted from Nasdaq and deregistered under the Securities Exchange Act of 1934, as amended.
