Rhea-AI Filing Summary

XOMA Royalty Corporation agreed to be acquired by Ligand Pharmaceuticals in an all-cash merger. XOMA common stockholders will receive $39.00 per share in cash plus contingent value rights tied to potential proceeds from certain Janssen-related litigation, giving both immediate value and additional upside potential.

The deal values XOMA at approximately $739 million and represents about a 14% premium to its 30‑day volume‑weighted average price before announcement. XOMA’s Series X preferred shares will convert to common stock, while its perpetual preferred shares will be redeemed with accrued dividends. A holding company reorganization and CVR structure will be completed before closing, and key shareholders owning roughly 47% of XOMA’s shares have agreed to support the transaction.

Positive

  • Value realization with upside: XOMA stockholders receive $39.00 per share in cash (about a 14% premium to the 30‑day VWAP) plus contingent value rights tied to 75% of net proceeds from specified Janssen litigation, combining immediate liquidity with additional potential returns.

Negative

  • None.

Insights

All-cash sale of XOMA with CVR upside and strong holder support.

XOMA Royalty has entered a definitive agreement to be acquired by Ligand for $39.00 per share in cash, implying roughly $739 million in equity value. Stockholders also receive a contingent value right for a share of 75% of net proceeds from specified Janssen litigation, adding potential upside beyond the cash payment.

The deal follows a structured process, includes a holding company reorganization and a CVR spin, and features customary closing conditions such as antitrust clearance and majority stockholder approval. A termination fee of $40,000,000 applies in defined break scenarios, which is typical for a transaction of this size.

Support agreements cover about 47% of outstanding shares as of April 27, 2026, increasing execution visibility. For Ligand, the transaction is positioned as immediately accretive, with higher 2026 revenue and EPS guidance, though those benefits accrue to Ligand’s shareholders, while XOMA holders realize value primarily through the sale price and CVR participation.

Contingent Value Right financial
"stockholders are expected to separately receive one non-transferable Contingent Value Right (“CVR”) per share"
A contingent value right is a special security that gives its holder the right to receive one or more future payments only if specified events happen, such as a product reaching a sales target or getting regulatory approval. It matters to investors because it offers potential extra payout tied to uncertain outcomes—like a bet that a project will succeed—so it can add upside to a deal while also carrying extra risk and valuation uncertainty.
Holding Company Reorganization regulatory
"Prior to the Effective Time, the Company will effect a holding company reorganization (the “Holding Company Reorganization”)"
Superior Proposal financial
"would reasonably be expected to lead to a Superior Proposal (as defined in the Merger Agreement)"
A superior proposal is a competing offer to buy or merge with a company that is materially better than an existing deal, typically offering higher cash, stronger terms, or fewer conditions. It matters to investors because it can raise the expected payout or change deal certainty—like getting a higher bid at an auction, a superior proposal can increase share value or prompt renegotiation of the transaction.
no-shop regulatory
"The Company has also agreed to customary “no-shop” restrictions on its ability to solicit acquisition proposals"
A no-shop is a contractual promise by a company that it will not seek, solicit, or negotiate alternative offers for a set period while a potential deal is being discussed. For investors, it matters because it increases the likelihood that a proposed transaction will proceed without competing bids, which can lock in a price or limit the chance of a higher offer; think of it like agreeing to date exclusively while one person decides whether to commit.

Item 1.01 Entry into a Material Definitive Agreement.

On April 27, 2026, XOMA Royalty Corporation, a Nevada corporation (the “Company” or “XOMA Royalty”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Ligand Pharmaceuticals Incorporated, a Delaware corporation (“Parent”), and Flex Merger Sub, Inc., a Nevada corporation and wholly-owned subsidiary of Parent (“Merger Sub”), pursuant to which, and upon the terms and subject to the conditions thereof, including, without limitation, effecting the Holding Company Reorganization (as defined below), Merger Sub will merge with and into HoldCo (as defined below) (the “Merger”), with HoldCo surviving the Merger as a wholly owned subsidiary of Parent.

Following the Holding Company Reorganization, unless the context otherwise requires, all references in this Current Report on Form 8-K to the “Company” or “XOMA Royalty” refer to HoldCo. Following the Holding Company Reorganization, HoldCo will assume all obligations of the Company under the Merger Agreement.

The Merger

Pursuant to the Merger Agreement, at the time the Merger becomes effective (the “Effective Time”), each share of common stock, par value $0.0075 per share, of the Company (the “Shares”) issued and outstanding immediately prior to the Effective Time (other than certain Shares to be canceled pursuant to the Merger Agreement and Dissenting Shares (as defined in the Merger Agreement)) will be automatically converted into the right to receive (i) $39.00 per Share in cash, without interest, and subject to deduction for any required withholding tax, plus (ii) an amount of contingent value rights (each, a “Contingent Value Right”) representing a right to receive contingent payments derived from the CVR Trust’s interest in RemainCo LLC (as defined below) in accordance with the CVR Agreement (as defined in the Merger Agreement) (as further described below under the heading “CVR Spin”) (clauses (i) and (ii) collectively, the “Merger Consideration”).

In addition, pursuant to the Merger Agreement, at the Effective Time, each (i) share of Series X Convertible Preferred Stock, par value $0.05 per share (the “Series X Preferred Stock”), of the Company (the “Series X Preferred Shares”) issued and outstanding immediately prior to the Effective Time will be converted, without any required action on the part of the holder thereof, into the right to receive the Merger Consideration with respect to the aggregate number of Shares for which the Series X Preferred Shares were convertible into immediately prior to the Effective Time pursuant to the terms of the Certificate of Designation of Series X Convertible Preferred Stock, without interest and subject to deduction for any required withholding tax, without regard to any limitations on exercise contained therein and (ii) each 8.625% Series A Cumulative Perpetual Preferred Stock, par value $0.05 per share (the “Series A Preferred Stock”) and 8.375% Series B Cumulative Perpetual Preferred Stock, par value $0.05 per share (the “Series B Preferred Stock”, together with the Series A Preferred Stock, the “Perpetual Preferred Stock” and collectively with the Series X Preferred Stock, the “Company Preferred Stock”), shall be redeemed in accordance with the terms of the applicable certificate of designation governing such Perpetual Preferred Stock, including payment of all accrued and unpaid dividends thereon through the date of such redemption.

The Merger Agreement also specifies the treatment of the Company’s outstanding equity awards and warrants in connection with the Merger.

The consummation of the Merger is subject to the satisfaction or waiver of customary conditions as set forth in the Merger Agreement, including (i) adoption and approval of the Merger Agreement by the holders of at least a majority of the combined voting power of the outstanding Shares pursuant to the Nevada Revised Statutes, as amended, (“NRS”), 92A.120(5) (the “Company Stockholder Approval”), (ii) the applicable waiting period (and any extensions thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, having expired or been terminated and (iii) the completion of the Holding Company Reorganization and the CVR Spin (as defined below) in accordance with the terms of the Merger Agreement. Parent and Merger Sub’s obligations to consummate the transactions contemplated by the Merger Agreement are not subject to any financing condition.

The Merger Agreement includes representations, warranties and covenants of the parties customary for a transaction of this nature. From the date of the Merger Agreement until the earlier of the Effective Time and the termination of the Merger Agreement, except as permitted by certain exceptions, including the consummation of the Holding Company Reorganization and the CVR Spin, the Company has agreed to conduct its business in the ordinary course of business in all material respects and has agreed to certain other operating covenants, as set forth more fully in the Merger Agreement.

 


The Company has also agreed to customary “no-shop” restrictions on its ability to solicit acquisition proposals from third parties and engage in discussions or negotiations with third parties regarding acquisition proposals.

Notwithstanding these restrictions, the Company may under certain circumstances provide information with respect to the Company to and participate in discussions or negotiations with third parties with respect to an unsolicited bona fide written acquisition proposal if the board of directors of the Company (the “Company Board”) has determined in good faith, after consultation with its outside legal counsel and financial advisors, that such acquisition proposal constitutes or would reasonably be expected to lead to a Superior Proposal (as defined in the Merger Agreement) and, after consultation with outside legal counsel and its financial advisors, that the failure to take such action would be inconsistent with the Company Board’s fiduciary duties under applicable law. The Merger Agreement also requires that the Company Board recommend that the stockholders of the Company vote in favor of the approval of the Merger Agreement (the “Company Board Recommendation”) and that the Company Board not, among other things, (i) (A) fail to make, withdraw, amend, modify, or materially qualify, in a manner adverse to Parent, the Company Board Recommendation, (B) fail to include the Company Board Recommendation in a proxy statement to be sent to the stockholders of the Company in connection with a meeting of the stockholders of the Company (the “Company Stockholders’ Meeting”) that is filed with the U.S. Securities and Exchange Commission (the “SEC”) or mailed to the Company’s stockholders, (C) recommend an acquisition proposal, (D) fail to recommend against acceptance of any tender offer or exchange offer for Shares within 10 business days after the commencement of such offer, (E) fail to reaffirm the Company Board Recommendation within 10 business days after the date any acquisition proposal (or material modification thereto) is first publicly disclosed by the Company or anyone making the acquisition proposal or (F) resolve or agree to take any of the foregoing actions (each such foregoing actions or failure to act, an “Adverse Recommendation Change”), or (ii) cause or permit the Company or any of its subsidiaries to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, or other similar contract relating to any acquisition approval. Notwithstanding these restrictions, the Company Board is permitted, prior to the Company Stockholders’ Meeting and subject to the terms and conditions set forth in the Merger Agreement, to (x) effect an Adverse Recommendation Change if an Intervening Event (as defined in the Merger Agreement) has occurred and if the Company Board determines in good faith, after consultation with outside legal counsel, that in light of the Intervening Event and taking into account any revised terms proposed by Parent, the failure to take such action would be inconsistent with its fiduciary duties under applicable law, or (y) effect an Adverse Recommendation Change or terminate the Merger Agreement in response to the receipt of an unsolicited bona fide written acquisition proposal that did not result from a material breach of the Company’s “no-shop” restrictions under the Merger Agreement if the Company Board determines in good faith, after consultation with outside legal counsel and financial advisors, that the failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties under applicable law and, after consultation with its outside legal counsel and financial advisors, that the acquisition proposal constitutes a Superior Proposal, subject in each case to certain matching rights in favor of Parent.

The Merger Agreement includes a remedy of specific performance for the parties thereto. The Merger Agreement also includes customary termination provisions for both the Company and Parent and provides that, in connection with the termination of the Merger Agreement under specified circumstances, including (i) by either the Company or Parent if the Merger has not occurred on or prior to January 26, 2027 or (ii) by either the Company or Parent if a final and non-appealable order or action in certain specified jurisdictions enjoins, restrains or prohibits consummation of the transactions contemplated by the Merger Agreement or (iii) by either the Company or Parent if the Company Stockholder Approval has not been obtained or (iv) by either the Company or Parent if the other party breaches its representations, warranties or covenants in the Merger Agreement in a way that would entitle the party seeking to terminate the Merger Agreement not to consummate the Merger, subject to the right of the breaching party to cure the breach or (v) by the Company if the Company Board authorizes the Company to enter into an alternative acquisition agreement for a Superior Proposal or (vi) by Parent if the Company Board makes an Adverse Recommendation Change.

The Company will be required to pay a termination fee of an amount in cash equal to $40,000,000 if (i) the Merger Agreement is terminated because the stockholder approval is not obtained or the transaction has not closed by the termination date, in each case after an acquisition proposal has been made or publicly disclosed and not publicly

 


withdrawn, and within 12 months thereafter the Company enters into or consummates a qualifying acquisition proposal, (ii) the Company terminates the Merger Agreement to enter into a Superior Proposal, or (iii) Parent terminates the Merger Agreement following an Adverse Recommendation Change.

The Company Board has duly and unanimously (i) determined that the transactions contemplated by the Merger Agreement, including the Merger, are advisable and fair to, and in the best interests of, the Company and its stockholders, (ii) approved the execution and delivery by the Company of the Merger Agreement, and (iii) resolved to make the Company Board Recommendation.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and which is incorporated herein by reference. The Merger Agreement has been filed to provide information to investors regarding its terms. The Merger Agreement is not intended to provide any other factual information about the Company, Parent or Merger Sub, their respective businesses, or the actual conduct of their respective businesses during the period prior to the consummation of the Merger or the other transactions contemplated therein. The Merger Agreement and this summary should not be relied upon as disclosure about the Company, Parent or Merger Sub. None of the Company’s stockholders or any other third parties should rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or conditions of the Company, Parent, Merger Sub or any of their respective subsidiaries or affiliates. The Merger Agreement contains representations and warranties that are the product of negotiations among the parties thereto and that the parties made to, and solely for the benefit of, each other as of specified dates. The assertions embodied in those representations and warranties are qualified in important part by confidential disclosure schedules delivered by the Company to Parent and Merger Sub in connection with the Merger Agreement. Moreover, certain representations and warranties in the Merger Agreement may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders or investors or may have been used for the purpose of allocating risk between the parties to the Merger Agreement instead of establishing these matters as facts. Accordingly, investors should consider the information in the Merger Agreement in conjunction with the entirety of the factual disclosure about the Company in the Company’s public reports filed with the SEC. Information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

Support Agreement

On April 27, 2026, in connection with the execution of the Merger Agreement, Parent entered into Voting and Support Agreements (the “Support Agreements”) with certain of the Company’s officers, directors and certain funds affiliated with BVF Partners (together with affiliated entities) (collectively, the “Supporting Stockholders”), in each case, in their respective capacity as a stockholder of the Company. Under the terms of the Support Agreements, the Supporting Stockholders have agreed, among other things, to vote their Shares in favor of the Merger Agreement and the other transactions contemplated by the Merger Agreement and to promptly following the date of the Merger Agreement convert all of their Series X Preferred Shares to Shares in order to permit them to vote the Shares issuable upon conversion in favor of the Company Stockholder Approval.

As of April 27, 2026, the Supporting Stockholders beneficially owned an aggregate of approximately 47% of the outstanding Shares. The Support Agreements will terminate upon termination of the Merger Agreement, the Effective Time and certain other specified events.

The foregoing description of the Support Agreements is not complete and is qualified in its entirety by reference to the full text of the Form of Support Agreement, which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.

Holding Company Reorganization

Prior to the Effective Time, the Company will effect a holding company reorganization (the “Holding Company Reorganization”) pursuant to NRS 92A.180 through 92A.199 (or such other applicable provisions of the NRS), whereby (i) a newly formed Nevada corporation and direct, wholly owned subsidiary of the Company (“HoldCo”), will become the holding company of the Company, which shall merge with and into the Company through a direct, wholly owned subsidiary of Holdco (“HoldCo Merger Sub”), with the Company surviving as a direct, wholly owned

 


subsidiary of HoldCo, (ii) each Share issued and outstanding immediately prior to the effectiveness of the Holding Company Reorganization will automatically be converted into one share of common stock of HoldCo, having the same rights, powers and preferences as such Share, (iii) each share of Company Preferred Stock issued and outstanding immediately prior to the effectiveness of the Holding Company Reorganization will automatically be converted into one share of a corresponding series of preferred stock of HoldCo, having the same designations, rights, powers, preferences, qualifications, limitations and restrictions as such share of Company Preferred Stock, and (iv) each Company equity-based award outstanding immediately prior to the effectiveness of the Holding Company Reorganization will be automatically converted into a corresponding award with respect to shares of HoldCo common stock (or, as applicable, HoldCo preferred stock), on the same terms and conditions. The Company will not effect the Holding Company Reorganization unless HoldCo’s articles of incorporation (including the designation of each series of HoldCo preferred stock with terms substantially identical to the corresponding series of Company Preferred Stock) and bylaws are in form and substance reasonably acceptable to Parent.

CVR Spin

Following the completion of the Holding Company Reorganization, the following transactions will be effected in the order set forth below (collectively, the “CVR Spin”):

 

  (i)

immediately prior to the Effective Time, HoldCo will cause the Company to transfer to HoldCo (or one or more designees of HoldCo) the HoldCo Business Assets and Business Liabilities (as each such term is defined in the Merger Agreement) (such transactions, collectively, the “Asset/Liability Transfer”);

 

  (ii)

following the Asset/Liability Transfer, HoldCo will cause the Company to convert from a Nevada corporation into a limited liability company (the “RemainCo Conversion” and the Company as so converted “RemainCo LLC”);

 

  (iii)

following the RemainCo Conversion, HoldCo will contribute 75% of the issued and outstanding limited liability company units of RemainCo LLC to the trust (the “CVR Trust”) established pursuant to the trust agreement to be entered into at or prior to the Effective Time by and among HoldCo, the trustee thereunder (the “Trustee”), and such other parties as may be appropriate (the “CVR Trust Agreement”) (the “Trust Contribution”), to be held and administered by the Trustee in accordance with the CVR Trust Agreement for the benefit of the holders of CVRs; and

 

  (iv)

following the Trust Contribution, HoldCo shall pay, on a pro rata basis, to each holder of record of HoldCo common stock and HoldCo preferred stock (on an as-converted-to-common basis) as of immediately prior to the Effective Time as additional Merger Consideration, CVRs representing the right to receive contingent payments derived from the CVR Trust’s interest in RemainCo LLC in accordance with the CVR Trust Agreement.

Following the date of the Merger Agreement, Parent will have the right to further assess the consequences of the Holding Company Reorganization and the CVR Spin. If Parent identifies any material adverse consequences, the parties will negotiate modifications. If no agreement is reached, the contemplated transaction structure may be replaced with an alternative CVR structure, wherein Parent will issue to each holder of record of Company common stock and Company preferred stock (on an as-converted-to-common basis) as of immediately prior to the Effective Time contingent value rights to receive 75% of net proceeds (if any) from the resolution of the Janssen Litigation (as defined in the Merger Agreement).

Item 8.01 Other Events.

On April 27, 2026, the Company and Parent issued a joint press release announcing the execution of the Merger Agreement. A copy of the press release is attached as Exhibit 99.1 and incorporated herein by reference.

You should carefully consider the foregoing factors and the other risks and uncertainties that affect the businesses of XOMA Royalty described in the “Risk Factors” and “Forward Looking Statements” sections of its Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other documents filed by either of them from time to time with the SEC, all of which are available at www.sec.gov. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and XOMA Royalty assumes no obligation to, and does not intend to, update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, unless required by law. XOMA Royalty gives no assurance that it will achieve its expectations.

Ligand to hold investor call at 8:00 a.m. ET today

JUPITER, Fla. and EMERYVILLE, Calif., April 27, 2026—Ligand Pharmaceuticals Incorporated (Nasdaq: LGND) and XOMA Royalty Corporation (“XOMA Royalty”) (Nasdaq: XOMA), both biotechnology royalty aggregators, today announced that the companies have entered into a definitive agreement under which Ligand will acquire XOMA Royalty for $39.00 per share of common stock in cash, for a total equity value of approximately $739 million. XOMA Royalty stockholders are expected to separately receive one non-transferable Contingent Value Right (“CVR”) per share entitling the holder to receive a portion of 75% of the net proceeds that may result from certain pending litigation at XOMA Royalty. The cash purchase price at close represents an approximately 14% premium to XOMA Royalty’s 30 trading day volume weighted average price as of April 24, 2026, the last trading day prior to announcement of the transaction.

“The acquisition of XOMA Royalty presents a compelling opportunity for us to strengthen and diversify our portfolio across all stages of clinical development and accelerate our long-term profitable growth. This acquisition will add seven marketed products and nearly double our portfolio of Phase 2 and 3 assets, which we believe will create significant value for our stockholders, all through a single transaction,” said Todd Davis, CEO of Ligand. “The XOMA Royalty team has built a robust portfolio of complementary biopharmaceutical assets, and this acquisition will enable us to further grow and diversify in areas such as ophthalmology, oncology, CNS and rare diseases. With XOMA Royalty, we believe we will now be in an even stronger position to leverage our expertise and capital base to support broader patient access and advance late-stage clinical programs in a way that enhances patient outcomes and improves lives.

With this agreement, Ligand adds over 120 commercial, clinical, and preclinical stage assets to its broad and growing royalty portfolio highlighted by Roche’s VABYSMO® (faricimab-svoa), Day One Pharmaceuticals’ OJEMDA (tovorafenib), Zevra Therapeutics’ MIPLYFFA (arimoclomol), and 14 programs in late-stage development, highlighted by Takeda’s mezagitamab and certain assets from Takeda’s externalized asset portfolio, including osavampator, volixibat and OHB-607. The addition of the XOMA Royalty portfolio is expected to increase Ligand’s long-term growth profile.


“After evaluating a broad range of strategic and financing alternatives, we believe combining our diverse portfolio with a company that shares our commitment to helping the biopharmaceutical industry thrive represents the most compelling outcome for XOMA Royalty’s stockholders,” said Owen Hughes, CEO of XOMA Royalty. “The structure delivers to our stockholders both the intrinsic value of XOMA’s portfolio today and the optionality associated with our ongoing litigation with Janssen Biotech (now Johnson & Johnson Innovative Medicine) via the CVR. Since 2023, we significantly scaled our portfolio with the addition of multiple assets and two platform technologies, enabling numerous upcoming regulatory and clinical catalysts beginning in 2026 and continuing over the next several years. We believe coupling Ligand’s business development capabilities, portfolio management expertise plus the inherent financial synergies from this transaction position the combined company to maximize long-term value across the combined portfolio.”

Transaction Terms

Under the terms of the merger agreement, Ligand will acquire all the outstanding shares of common stock of XOMA Royalty for $39.00 per share in cash. The cash consideration for the transaction is expected to be funded with Ligand’s existing cash on hand and borrowings under Ligand’s existing credit facility. XOMA Royalty’s Series X Convertible Preferred Stock is expected to be converted into shares of common stock at its stated fixed price prior to closing, whereas the outstanding shares of Series A Preferred Stock and Series B Preferred Stock are expected to be redeemed. XOMA Royalty stockholders also will receive one CVR per share. The CVRs are intended to provide XOMA Royalty stockholders with the opportunity to receive certain net proceeds, if any are recovered, from certain ongoing litigation with regard to XOMA Royalty’s dispute with Janssen Biotech regarding the commercialization of TREMFYA®.

The transaction has been unanimously approved by the Ligand and XOMA Royalty Boards of Directors.
