Rhea-AI Filing Summary

Theravance Biopharma has agreed to be acquired by Zymeworks in a cash-and-CVR deal. Zymeworks will buy Theravance Biopharma for $17.00 per share in cash, valuing the company at approximately $929 million, plus a contingent value right (CVR) tied to future monetization of the drug ampreloxetine.

Each CVR gives holders 80% of net proceeds from any license, divestiture or other monetization of ampreloxetine over ten years, plus a share of specified milestone and royalty payments as described in the CVR agreement. The price represents a 22% premium to the March 3, 2026 closing price and a 10% premium to the volume-weighted average price since that date. Closing is targeted for the second half of 2026, subject to shareholder approval, antitrust clearance and other customary conditions.

Positive

  • Premium cash acquisition with additional upside: Zymeworks will acquire Theravance Biopharma for $17.00 per share in cash, implying equity value of about $929 million and providing 22% and 10% premiums to the March 3, 2026 closing price and subsequent VWAP, plus CVR upside on ampreloxetine.

  • None.

Insights

Zymeworks is acquiring Theravance in a premium cash deal with upside via CVRs.

The agreement delivers $17.00 per share in cash, implying equity value around $929 million. On top of this, shareholders receive a contingent value right giving 80% of net proceeds from any future monetization of ampreloxetine over a 10-year period.

The announced cash price carries a 22% premium to the March 3, 2026 close and a 10% premium to the volume-weighted average price since that date. This follows a multi-year strategic review that included monetizing the TRELEGY royalty interest for $225 million in 2025 and restructuring actions.

Deal completion depends on Theravance shareholders approving the merger, obtaining Hart-Scott-Rodino clearance, and the absence of a continuing material adverse effect. A termination and reverse termination fee of $32,515,000 each reinforces commitment, while Parent has secured debt financing from OMERS Life Sciences and the merger is not conditioned on financing.

contingent value right financial
"one contingent value right, which will represent the right to receive the CVR Payment Amount"
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.
Hart-Scott-Rodino Antitrust Improvements Act of 1976 regulatory
"the expiration or termination of any waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976"
material adverse effect financial
"the absence of a material adverse effect with respect to the Company that is continuing"
A material adverse effect is a significant negative change or event that substantially reduces a company’s business, financial condition, or future prospects — think of it like a sudden major engine failure that makes a car unreliable. Investors care because such an event can lower expected profits, trigger contract clauses (allowing counterparties to renegotiate or walk away), and prompt swift stock-price reassessment based on the higher risk and uncertainty.
reverse termination fee financial
"Parent will be required to pay the Company a reverse termination fee of $32,515,000"
A reverse termination fee is a cash payment the would-be buyer agrees to pay the target if the buyer fails to close a merger or acquisition for specified reasons, such as losing financing or failing to obtain approvals. Think of it like a breakup fee the buyer agrees to pay as compensation for the seller’s lost time and missed opportunities; investors watch it because it signals deal certainty, potential cash recovery if a deal collapses, and shifts financial risk between the parties.
extraordinary general meeting regulatory
"an extraordinary general meeting of the Company for the purpose of approving the Merger Agreement"
Superior Proposal financial
"determines in good faith... that such Acquisition Proposal constitutes a Superior Proposal"
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.

Item 1.01Entry into a Material Definitive Agreement.

 

Agreement and Plan of Merger

 

On June 28, 2026, Theravance Biopharma, Inc., an exempted company with limited liability incorporated under the Laws of the Cayman Islands (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Zymeworks Inc., a Delaware corporation (“Parent”), and Zymeworks Merger Sub 1, an exempted company with limited liability incorporated under the Laws of the Cayman Islands and a wholly owned subsidiary of Parent (“Merger Sub”), providing for the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent (the “Surviving Company”). Capitalized terms used herein and not otherwise defined herein have the meanings set forth in the Merger Agreement.

 

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions set forth therein, at the effective time of the Merger (the “Effective Time”), each ordinary share, par value $0.00001 per share, of the Company (“Ordinary Share”) issued and outstanding immediately prior to the Effective Time (other than Canceled Shares and Dissenting Shares) will be canceled and converted into the right to receive (i) $17.00 in cash, without interest (the “Per Share Cash Consideration”), and (ii) one contingent value right, which will represent the right to receive the CVR Payment Amount (as defined below), if any, at the times and subject to the terms and conditions provided for in the CVR Agreement (as defined and further described below), in cash, without interest (each, a “CVR” and, collectively, the “CVRs” and each CVR together with the Per Share Cash Consideration, the “Per Share Merger Consideration”).

 

At the Effective Time, each:

 

·Company Option, whether vested or unvested, that is outstanding, unexercised and not yet expired as of immediately prior to the Effective Time will be canceled and converted into the right to receive, in full satisfaction of the rights of such holder, an amount in cash, without interest, equal to (i) the excess, if any, of the Per Share Cash Consideration over the exercise price of such Company Option, multiplied by (ii) the number of Ordinary Shares underlying such Company Option (subject to any required tax withholdings as provided in the Merger Agreement) plus (iii) one CVR for each Ordinary Share underlying such Company Option. However, any Company Option that has an exercise price per Ordinary Share that is greater than or equal to the Per Share Cash Consideration will cease to be outstanding, be canceled and cease to exist and the holder of any such Company Option will not be entitled to payment of the Per Share Merger Consideration.

 

·Company RSU Award that is outstanding immediately prior to the Effective Time, whether vested or unvested, will be canceled and automatically converted into a right to receive an amount in cash, without interest, equal to (i) the Per Share Closing Consideration multiplied by (ii) the number of Ordinary Shares underlying such Company RSU Award (subject to any required tax withholdings as provided in the Merger Agreement) plus (iii) one CVR for each Ordinary Share underlying such Company RSU Award.

 

·Company PSU Award that is outstanding immediately prior to the Effective Time, whether vested or unvested, will be canceled in exchange for the right to receive an amount in cash, without interest, equal to (i) the Per Share Cash Consideration multiplied by (ii) the number of Ordinary Shares with respect to such Company PSU Award that remain outstanding and unreleased as of immediately prior to the Effective Time, plus (iii) one CVR for each Ordinary Share underlying such Company PSU Award.

 

Consummation of the Merger is subject to customary closing conditions, including, without limitation, the absence of certain legal restraints preventing or otherwise making illegal the consummation of the Merger, the absence of a material adverse effect with respect to the Company that is continuing, the expiration or termination of any waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, applicable to the Merger (“HSR Act Clearance”) and the approval of the Merger Agreement, the Merger and the other transactions contemplated thereby by the affirmative vote of holders of Ordinary Shares representing at least two-thirds of the Ordinary Shares (the “Company Requisite Vote”) present and voting in person or by proxy as a single class at an extraordinary general meeting of the Company for the purpose of approving the Merger Agreement, the Merger and the other transactions contemplated thereby (the “Shareholder Meeting”).

 

The parties expect the Merger and the other transactions contemplated by the Merger Agreement to close in the second half of 2026. The Merger Agreement provides that as promptly as reasonably practicable after the date of the Merger Agreement, the Company, with the good faith cooperation of Parent and Merger Sub, will prepare and file a preliminary proxy statement relating to the Shareholder Meeting.

 

On or prior to the Closing Date, Parent and a rights agent selected by the Company and reasonably acceptable to Parent (the “Rights Agent”) will enter into a Contingent Value Rights Agreement, in the form attached as Exhibit A to the Merger Agreement, with such changes as may be permitted by the Merger Agreement (the “CVR Agreement”).

 

The Company has made customary representations and warranties in the Merger Agreement and has agreed to customary covenants regarding the operation of the business of the Company and its subsidiaries prior to the Effective Time. The Company is also subject to customary restrictions on its ability to solicit Acquisition Proposals from third parties and to provide non-public information to, and participate in discussions and engage in negotiations with, third parties regarding Acquisition Proposals, with customary exceptions to allow the Board of Directors of the Company (the “Board of Directors”) to exercise its fiduciary duties. These exceptions include that, subject to the terms and conditions of the Merger Agreement, if the Company receives an Acquisition Proposal that did not result from the Company’s breach of its non-solicitation covenants, and following such receipt, the Board of Directors, upon the recommendation of the Strategic Review Committee, determines in good faith, after consultation with its financial advisor and outside legal counsel that such Acquisition Proposal constitutes a Superior Proposal or would reasonably be expected to result in a Superior Proposal.

  

 

 

 

Prior to obtaining the Company Requisite Vote, the Board of Directors may, in certain circumstances and upon the recommendation of the Strategic Review Committee, effect a Change of Recommendation, subject to complying with specified notice and other conditions set forth in the Merger Agreement.

 

The Merger Agreement contains certain customary termination rights for the Company and Parent. Subject to the terms and conditions of the Merger Agreement, the Company or Parent may terminate the Merger Agreement if the Merger is not consummated by December 28, 2026, which period may be extended automatically for two three-month periods if at the end of the prior period, all conditions to closing of the Merger other than conditions relating to HSR Act Clearance have been satisfied or waived as of such date (the “End Date”).

 

Upon termination of the Merger Agreement, in specified circumstances, the Company will be required to pay Parent a termination fee of $32,515,000. Such circumstances include, among others, where the Merger Agreement is terminated prior to the Company Requisite Vote (i) in connection with the Company accepting a Superior Proposal and entering into an Alternative Acquisition Agreement for the consummation of a transaction that the Board of Directors determines constitutes a Superior Proposal and (ii) due to the Board of Directors’ Change of Recommendation.

 

The Merger Agreement further provides that Parent will be required to pay the Company a reverse termination fee of $32,515,000 in the event the Merger Agreement is terminated in certain specified circumstances, including if the Merger is not consummated before the End Date because certain conditions related to HSR Act Clearance have not been satisfied or waived.

 

Parent has obtained a debt financing commitment from OMERS Life Sciences for the purpose of financing the transactions contemplated by the Merger Agreement. The obligation of Parent and Merger Sub to consummate the Merger is not subject to any financing condition or the receipt of any financing by the Parent.

 

The representations, warranties and covenants of the Company contained in the Merger Agreement have been made solely for the benefit of Parent and Merger Sub. In addition, such representations, warranties and covenants (i) have been made only for purposes of the Merger Agreement and (ii) have been included in the Merger Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as fact. In addition, the representations, warranties and covenants have been qualified by (A) matters specifically disclosed in certain of the Company’s filings with the United States Securities and Exchange Commission (“SEC”), (B) confidential disclosures made to Parent and Merger Sub in the disclosure letter delivered in connection with the Merger Agreement, and (C) materiality qualifications contained in the Merger Agreement, which may differ from what may be viewed as material by investors. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the Company or its business.

 

Contingent Value Rights Agreement

 

Pursuant to the Merger Agreement, on or prior to the Closing Date, Parent and the Rights Agent will enter into the CVR Agreement governing the terms of the CVRs (the “CVR Agreement”). The CVRs are contractual rights only and are not transferable except under certain limited circumstances, will not be evidenced by a certificate or other instrument and will not be registered with the SEC or listed for trading. The CVRs will not have any voting or dividend rights and will not represent any equity or ownership interest in Parent, any constituent company to the Merger or any of their respective subsidiaries.

 

Each CVR represents a non-tradeable contractual contingent right to receive (i) a pro rata share of 80% of the net proceeds (the “License Proceeds”) received by Parent or its affiliates (including the Surviving Company) from any license, divestiture or other monetization transaction of ampreloxetine (a “CVR Product License”) executed within the ten (10)-year period following the Effective Time (the “CVR License Expiration Date”), (ii) a pro rata share of $50 million in cash (the “First Commercial Sale Milestone Payment”) upon the first commercial sale of ampreloxetine by Parent or its affiliates (including the Surviving Company) in the U.S., UK, Spain, France, Germany or Italy on or prior to the CVR License Expiration Date and (iii) a pro rata share of 10% of the net sales (the “Royalties” and, together with the License Proceeds and the First Commercial Sale Milestone Payment, the “CVR Payment Amount”) received by Parent or its affiliates (including the Surviving Company), on a country-by-country basis, from the date of the first commercial sale until the later of the 10th anniversary of such date, patent expiration or the loss of exclusivity, in each case, subject to the terms and conditions of the CVR Agreement.

 

There can be no assurance (i) that a CVR Product License will be executed, or the First Commercial Milestone will occur, as of or prior to the CVR License Expiration Date (ii) that any License Proceeds or Royalties will become payable to Parent or its affiliates or (iii) that Parent will be required to make any CVR Payment Amount to holders of the CVRs.

THERAVANCE BIOPHARMA ENTERS INTO DEFINITIVE AGREEMENT TO BE ACQUIRED BY ZYMEWORKS FOR $17.00 PER SHARE IN CASH PLUS A CONTINGENT VALUE RIGHT

 

·Theravance Biopharma shareholders to receive $17.00 per share in cash, representing an equity value of approximately $929 million
·Theravance Biopharma shareholders to receive a contingent value right (CVR) entitling them to 80% of net proceeds from any future license, divestiture or other monetization of ampreloxetine within the next ten years
·Transaction follows a comprehensive strategic alternatives review conducted by the Company’s Strategic Review Committee and Board of Directors
·Transaction expected to close in the second half of 2026, subject to shareholder approval and customary closing conditions

 

DUBLIN, IRELAND – June 29, 2026 – Theravance Biopharma, Inc. (“Theravance Biopharma” or the “Company”) (Nasdaq: TBPH) today announced that it has entered into a definitive agreement pursuant to which Zymeworks Inc. will acquire the Company for $17.00 per share in cash, representing an equity value of approximately $929 million. In addition to the cash consideration, Theravance Biopharma shareholders will receive a CVR entitling them to 80% of net proceeds realized from any future license, divestiture or other monetization of ampreloxetine over the next ten years, with the remaining 20% to Zymeworks.

 

The price per share represents a premium of 22% to the Company’s closing stock price on March 3, 2026, the day the Company announced topline results from the ampreloxetine Phase 3 CYPRESS study, and a premium of 10% to Theravance Biopharma’s volume weighted average price since the same date.

 

The transaction is the culmination of a comprehensive strategic review process conducted by the Company's Strategic Review Committee and Board of Directors, which considered a broad range of alternatives. Since its formation in 2024, the Strategic Review Committee, working with Lazard, has overseen a series of actions to maximize shareholder value, including the monetization of the Company’s TRELEGY® royalty interest for $225 million in 2025, scenario planning for different potential outcomes for the CYPRESS Phase 3 study, and the evaluation of a broad range of strategic alternatives leading to today’s transaction. During this period, Theravance Biopharma also implemented an organizational restructuring.

 

 

 

 

“After evaluating a broad range of strategic alternatives, the Strategic Review Committee and full Board of Directors determined that this transaction achieves the greatest value for Theravance Biopharma shareholders," said Susannah Gray, independent Chair of the Board and Chair of the Strategic Review Committee. “We believe this transaction recognizes the value of our assets, including our interest in YUPELRI®, the potential TRELEGY® milestone payment, a robust balance sheet and Irish tax attributes. In addition to delivering immediate cash to shareholders, this transaction also preserves the opportunity for them to benefit from any future value that may be realized from ampreloxetine through the contingent value right.”

 

“We are proud of what Theravance Biopharma has accomplished over the past several years, including the successful development and commercialization of YUPELRI®, which has become an important treatment option for patients with COPD. Additionally, we continue to explore whether there is a path to bring ampreloxetine to patients with MSA and nOH, a community with high unmet medical need," said Rick E Winningham, Chief Executive Officer of Theravance Biopharma. “Our achievements would not have been possible without the dedication and commitment of our team, whose contributions helped the Company reach this outcome and make a difference for patients around the world.”

 

Transaction Details

Exhibit 99.2

 

Employee Note from Rick

 

To: All Theravance Biopharma Employees

From: Rick E Winningham, CEO

Subject: Theravance Biopharma’s Next Chapter

 

Dear Theravance Biopharma Employees,

 

Today, we announced that we have entered into a definitive agreement to be acquired by Zymeworks for $17.00 per share in cash, plus a contingent value right that provides shareholders with the opportunity to benefit from any future license, divestiture or other monetization of ampreloxetine over the next ten years. Zymeworks is a global biotechnology company headquartered in Vancouver and shares our belief in the long-term potential of YUPELRI and the strength of the franchise this team has helped build.

 

After carefully evaluating a broad range of strategic alternatives, our Board of Directors determined that this transaction achieves the greatest value for our company and our shareholders. We believe this agreement provides the best path forward to support the continued growth of YUPELRI and build on the strong foundation this team has created. You can learn more about the transaction and the definitive agreement in our press release here [LINK].

 

While today is an important moment for us, this is just the first step in the process. Theravance Biopharma and Zymeworks remain separate companies until the transaction closes, which we expect to occur in the second half of 2026. Until then, it’s critical that we remain focused on our day-to-day responsibilities across our company and continue delivering for our patients and one another.

 

We will hold a company meeting when everyone is back from the holiday to discuss the announcement in more detail. In the meantime, I am attaching an FAQ to this email to help address some of the immediate questions you may have. While we may not have all the answers today, we are committed to communicating openly and sharing updates as we have more to share.

 

Because this announced transaction involves two public companies, all external communications must remain coordinated. We have adopted a “no social media comment” policy about the transaction with Zymeworks. You should not post to social media or share, comment on, or like posts by others that relate to the transaction.

 

This announcement marks a significant moment for Theravance Biopharma and for many of us personally. Across the many chapters of our company, this team has been guided by our Core Values and a shared commitment to making a difference in the lives of patients and caregivers. That purpose is larger than any one role or milestone, and it continues to guide our work for the patients and caregivers who rely on us. I hope each of you feels proud of the impact you have helped create and the way this team continues to support one another. On behalf of the entire leadership team, thank you for all you have done and all you will continue to do for the patients and caregivers we serve.

 

Sincerely,

Rick

FAQ

What is Zymeworks paying to acquire Theravance Biopharma (TBPH)?

Zymeworks will pay $17.00 in cash for each Theravance Biopharma ordinary share, valuing the company at approximately $929 million. In addition, shareholders receive a contingent value right linked to future monetization of ampreloxetine, potentially adding further cash payments if specified milestones and proceeds are realized.

What contingent value right (CVR) do TBPH shareholders receive in this deal?

Each Theravance Biopharma share also receives a CVR giving 80% of net proceeds from any future license, divestiture or monetization of ampreloxetine over ten years. CVR holders may also share in a $50 million first commercial sale milestone payment and 10% net sales royalties, subject to the CVR agreement conditions.

What premium does the Zymeworks acquisition offer to TBPH shareholders?

The $17.00 per share cash price represents a 22% premium to Theravance Biopharma’s March 3, 2026 closing share price. It also reflects a 10% premium to the company’s volume-weighted average share price since that date, before considering any additional value from the ampreloxetine-linked CVR component.

When is the Theravance Biopharma–Zymeworks transaction expected to close?

The companies expect the merger to close in the second half of 2026. Timing depends on obtaining Theravance Biopharma shareholder approval, securing required regulatory clearances, including Hart-Scott-Rodino antitrust clearance, and satisfying other customary closing conditions outlined in the Agreement and Plan of Merger.

What are the key conditions and termination fees for the TBPH–Zymeworks merger?

Closing requires shareholder approval with at least two-thirds of votes cast in favor, antitrust clearance and no continuing material adverse effect. Either side may owe a $32,515,000 termination fee in specified circumstances, including certain competing bids or HSR-related delays past the end date as defined in the merger agreement.
