Under the Transaction Agreement, at the effective time of the Scheme of Arrangement (dthe “Effective Time”), ~~Exhibits~~all ordinary shares, nominal value £0.05 per share (each a “Company Share”), issued and outstanding as of the Effective Time will be acquired by Bidco, and the holders of Company Shares will have the right to receive, for each such share, $13.375 in cash, without interest (the “Consideration”).

99.1						Press Release issued on April 29, 2025

The Transaction Agreement contains customary representations, warranties and covenants, including covenants obligating the Company to use commercially reasonable efforts to conduct its operations in all material respects in its ordinary course of business consistent with past practice, to cooperate in seeking regulatory approvals and not to engage in certain specified activities without Parent’s prior written consent. In addition, subject to certain exceptions, the Company has agreed not to solicit, initiate, knowingly encourage or knowingly facilitate, any inquiry, proposal or offer that constitutes or would reasonably be expected to lead to an Acquisition Proposal (as defined in the Transaction Agreement), or take certain other restricted actions in connection therewith. Notwithstanding the foregoing, if the Company receives a written, bona fide Acquisition Proposal that did not result from a material breach of the non-solicitation provisions of the Transaction Agreement that the Company’s Board of Directors (the “Board”) determines in good faith, after consultation with its financial advisor(s) and outside legal counsel, constitutes or is reasonably likely to lead to a Superior Proposal (as defined in the Transaction Agreement), the Company may take certain actions to participate in discussions and negotiations and furnish information with respect to such Acquisition Proposal, after providing written notice to Parent of such determination.

~~SIGNATURES~~The Company will prepare and file a proxy statement with the U.S. Securities and Exchange Commission (the “SEC”) and, subject to certain exceptions, the Board will recommend that the Company’s shareholders vote in favor of the Scheme of Arrangement at the scheme meeting and the shareholder resolution at the general meeting of the Company’s shareholders to be convened in connection with the Scheme of Arrangement (the “Company Board Recommendation”). However, subject to the satisfaction of certain terms and conditions, the Company and the Board, as applicable, are permitted to take certain actions which may, as more fully described in the Transaction Agreement, include changing the Company Board Recommendation and entering into a definitive agreement with respect to a Superior Proposal if, among other things, the Board has concluded in good faith after consultation with its outside legal counsel that the failure to take such action would be reasonably likely to be inconsistent with the Board’s fiduciary duties under applicable law.

~~Pursuant~~The Transaction Agreement also contains certain customary termination rights in favor of each of the Company and Parent, including the Company’s right, subject to certain limitations, to terminate the ~~requirements~~Transaction ofAgreement in certain circumstances to accept a Superior Proposal and Parent’s right to terminate the ~~Securities~~Transaction ~~Exchange~~Agreement ~~Act~~if ofthe ~~1934~~Board changes its Company Board Recommendation. In addition, either Parent or the ~~registrant~~Company may terminate the Transaction Agreement if the Transaction has ~~duly~~not ~~caused~~been ~~this~~successfully ~~report~~completed toby January 8, 2026 (the “Termination Date”), which may be ~~signed~~automatically onextended ~~its~~by ~~behalf~~an additional three months (not to exceed two automatic extensions) if any closing conditions relating to regulatory approvals have not been satisfied but all other closing conditions have been satisfied or waived. In connection with a termination of the Transaction Agreement under specified circumstances, including due to a change in the Company Board Recommendation, the entry by the ~~undersigned~~Company ~~hereunto~~into ~~duly~~a ~~authorized~~definitive agreement with respect to a Superior Proposal, or certain other triggering events, such as if the High Court of Justice of England and Wales (the “Court”) declines or refuses to sanction the Scheme of Arrangement and the Company shall have communicated to the Court at the hearing to sanction the Scheme of Arrangement that the Board no longer supports the consummation of the Transaction or no longer wishes the Court to sanction the Scheme of Arrangement, the Company may be required to pay Parent a termination fee of $100,000,000.

	Title:	President and Chief Executive Officer

The Board has unanimously resolved (i) that the Transaction Agreement, the Scheme of Arrangement and the transactions contemplated hereby and thereby are in the best interests of the Company and would promote the success of the Company for the benefit of the Company’s Shareholders as a whole, (ii) that the execution, delivery and performance of this Agreement and the Scheme of Arrangement and the consummation of the transactions contemplated hereby and thereby, be and are approved and (iii) to recommend to the Company Shareholders the approval of the Scheme of Arrangement at the scheme meeting and the passing of the shareholder resolution at the general meeting of the Company Shareholders to be convened in connection with the Scheme of Arrangement.

The foregoing description of the Transaction Agreement and the transactions contemplated thereunder is not complete and is qualified in its entirety by reference to the Transaction Agreement, a copy of which is hereby filed as Exhibit 2.1 to this Current Report on Form 8-K (this “Current Report”) and incorporated herein by reference. The Transaction Agreement and the foregoing description thereof have been included to provide investors and shareholders with information regarding the terms of the Transaction Agreement. They are not intended to provide any other factual information about the Company. The representations, warranties and covenants contained in the Transaction Agreement were made only as of specified dates for the purposes of such agreement, were solely for the benefit of the parties to such agreement and may be subject to qualifications and limitations agreed upon by such parties. In particular, in reviewing the representations, warranties and covenants contained in the Transaction Agreement and discussed in the foregoing description, it is important to bear in mind that such representations, warranties and covenants were negotiated with the principal purpose of allocating risk between the parties, rather than establishing matters as facts. Such representations, warranties and covenants may also be subject to a contractual standard of materiality different from those generally applicable to shareholders and reports and documents filed with the SEC, and are also qualified in important part by a confidential disclosure schedule delivered by the Company to Parent in connection with the Transaction Agreement. Investors and shareholders are not third-party beneficiaries under the Transaction Agreement. Accordingly, investors and shareholders should not rely on such representations, warranties and covenants as characterizations of the actual state of facts or circumstances described therein. Information concerning the subject matter of such representations, warranties and covenants may change after the date of the Transaction Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures.

Item 8.01. Other Events.

Forward Looking Statements

This communication includes “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995, including with respect to the proposed acquisition of Verona Pharma, and readers are cautioned not to place undue reliance on such statements. Such forward-looking statements include, but are not limited to, the ability of Merck and Verona Pharma to complete the transactions contemplated by the transaction agreement, including statements about the transaction contemplated thereby, statements about the expected timetable for completing the transaction, Verona Pharma’s beliefs and expectations and statements about the benefits sought to be achieved in the proposed acquisition, the potential effects of the acquisition on Verona Pharma, as well as the expected benefits and success of Verona Pharma’s products and product candidates. These statements are based upon the current beliefs and expectations of Verona Pharma’s management and are subject to significant risks and uncertainties. There can be no guarantees that the conditions to the closing of the proposed transaction will be satisfied on the expected timetable or at all, or that any pipeline candidates will receive the necessary regulatory approvals or that they will prove to be commercially successful. If underlying assumptions prove inaccurate or risks or uncertainties materialize, actual results may differ materially from those set forth in the forward-looking statements.

Risks and uncertainties include, but are not limited to, uncertainties as to the timing of the proposed transaction; the risk that competing offers or acquisition proposals will be made; the possibility that various conditions to the consummation of the proposed transaction contained in the transaction agreement may not be satisfied or waived (including, but not limited to, the failure to obtain the approval of the proposed transaction by Verona Pharma shareholders and the failure to obtain the sanction of the High Court of Justice of England and Wales); the effects of disruption from the transactions contemplated by the transaction agreement and the impact of the announcement and pendency of the transactions on Verona Pharma’s business; the risk that shareholder litigation in connection with the transaction may result in significant costs of defense, indemnification and liability; Verona Pharma’s dependence on the successful commercialization of Ohtuvayre and the uncertain market acceptance of Ohtuvayre as a treatment for COPD; and risks related to pharmaceutical product development, including Verona Pharma’s ongoing development of ensifentrine and any other product candidates and combinations, and the uncertainty of clinical success.

Verona Pharma undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by law. Additional factors that could cause results to differ materially from those described in the forward-looking statements can be found in Verona Pharma’s Annual Report on Form 10-K for the year ended December 31, 2024 and Verona Pharma’s other filings with the SEC.
