Theravance Biopharma, Inc.

Item 5.07. Submission of Matters to a Vote of Security Holders. Theravance Biopharma, Inc. (“Theravance Biopharma” or the “Company”) held an extraordinary general meeting on September 18, 2026 (the “Extraordinary General Meeting”). At the Extraordinary General Meeting, the Company’s shareholders were asked to consider and vote on three proposals related to the Agreement and Plan of Merger, dated as of June 28, 2026 (as it may be amended, supplemented and restated from time to time, the “Merger Agreement”), by and among the Company, 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”), each of which is described in further detail in the Company’s definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission (the “SEC”) and first mailed to shareholders on or about August 21, 2026 (as amended and supplemented, the “Definitive Proxy Statement”). The Merger Agreement provides that, among other things, on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into the Company (the “Merger”), with the Company continuing as the surviving company and becoming a wholly owned subsidiary of Parent as a result of the Merger (the “Surviving Company”). As of the close of business on July 31, 2026, the record date for the Extraordinary General Meeting, there were 51,918,754 ordinary shares, par value of $0.00001 each, of Theravance Biopharma (“ordinary shares”) outstanding and entitled to vote. Each ordinary share was entitled to one vote with respect to each proposal at the Extraordinary General Meeting. A total of 41,086,774 ordinary shares were represented in person or by proxy, representing 79.14% of the ordinary shares entitled to vote at the Extraordinary General Meeting, which constituted a quorum to conduct business at the Extraordinary General Meeting. At the Extraordinary General Meeting, the Company’s shareholders were asked to consider and vote on the following matters: Proposal No. 1 — As a special resolution, to approve and authorize (a) the execution, delivery and performance by Theravance Biopharma of the Merger Agreement, a copy of which is included as Annex A to the Definitive Proxy Statement, and the other agreements or documents contemplated by the Merger Agreement or any document or instrument delivered in connection thereunder (collectively, the “Transaction Documents”) to which Theravance Biopharma is a party, (b) the Plan of Merger, substantially in the form included as Annex B to the Definitive Proxy Statement, (c) the merger of Theravance Biopharma with Merger Sub so that Theravance Biopharma will be the Surviving Company and all the undertaking, property and liabilities of Merger Sub vest in Theravance Biopharma by virtue of such merger pursuant to the Companies Act (As Revised) of the Cayman Islands, (d) the amendment and restatement of the Amended and Restated Memorandum and Articles of Association of the Company by their deletion in their entirety and the substitution in their place of the amended and restated memorandum and articles of association in the form annexed as Schedule 2 of the Plan of Merger, (e) the increase of the authorized share capital of the Surviving Company from $2,002.30 divided into 200,000,000 ordinary shares of a nominal or par value of $0.00001 each and 230,000 preferred shares of a nominal or par value of $0.00001 each to $50,000.00 divided into 50,000 ordinary shares of a nominal or par value of $1.00 each as provided by the Plan of Merger, and (f) the consummation of the transactions contemplated by the Merger Agreement and the Contingent Value Rights Agreement, in the form attached as Exhibit A to the Merger Agreement and included as Annex C to the Definitive Proxy Statement (collectively, the “Transactions”) (including the Merger), upon the terms and subject to the conditions set forth therein (the “Merger Proposal”). Proposal No. 2 — As an ordinary resolution, to approve, on a non-binding, advisory basis, the compensation that will or may become payable to the named executive officers of Theravance Biopharma in connection with the Merger, as disclosed pursuant to Item 402(t) of Regulation S-K in the section of the Definitive Proxy Statement captioned “The Merger — Interests of the Company’s Directors and Executive Officers in the Merger — Potential Payments to Executive Officers upon Termination in Connection with a Change in Control,” including the tables under the section of the Definitive Proxy Statement captioned “Golden Parachute Compensation” (the “Advisory Merger-Related Compensation Proposal”). ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── Proposal No. 3 — As an ordinary resolution, that the Extraordinary General Meeting be adjourned to a later date or dates to be determined by the chairperson of the Extraordinary General Meeting, if necessary, (a) to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Extraordinary General Meeting, there are insufficient votes to approve the Merger Proposal, (b) to the extent necessary, to ensure that any required supplement or amendment to the accompanying proxy statement is provided to Theravance Biopharma shareholders, (c) if, as of the time for which the Extraordinary General Meeting is scheduled, there are insufficient ordinary shares represented (either in person or by proxy) to constitute a quorum necessary to conduct business at the Extraordinary General Meeting or (d) if required by law (the “Adjournment Proposal”). Based on the final, certified voting report provided by the independent inspector of election, the Company’s shareholders approved the Merger Proposal and the Advisory Merger-Related Compensation Proposal. The table below sets forth the voting results for each proposal. Proposal 1 - The Merger Proposal Votes For Votes Against Abstentions ────────────────────────────────────────────────── 40,993,370 8,671 84,733 The Merger Proposal was approved by the holders of more than two-thirds of the ordinary shares, which satisfies one of the closing conditions under the Merger Agreement for consummation of the Merger. Proposal 2 - The Advisory Merger-Related Compensation Proposal Votes For Votes Against Abstentions ────────────────────────────────────────────────── 40,587,829 470,381 28,564 The Advisory Merger-Related Compensation Proposal was approved by the requisite vote of Company shareholders required to approve such proposal. Proposal 3 - The Adjournment Proposal As a quorum was present and there were sufficient votes to approve the Merger Proposal, the Adjournment Proposal was unnecessary and the vote on the Adjournment Proposal was not determined. Because none of the proposals before the Extraordinary General Meeting were “routine” matters, there were no broker non-votes occurring in connection with these proposals at the Extraordinary General Meeting. No other business properly came before the Extraordinary General Meeting. Subject to the satisfaction or waiver of all of the conditions to the closing of the Merger in the Merger Agreement, the Merger is expected to be completed on or about September 23, 2026.
