Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.
On August 24, 2026, in connection with the scheme of arrangement under Part 26 of the United Kingdom Companies Act 2006 (the “Scheme”), which is expected to become effective on September 3, 2026 and is contemplated by the Agreement and Plan of Merger, dated September 29, 2025, by and among Barinthus Biotherapeutics plc (the “Company”), Beacon Topco, Inc., a Delaware corporation and a direct wholly owned subsidiary of the Company (“Topco”), Cdog Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Topco, and Clywedog Therapeutics, Inc., a Delaware corporation (as amended, the “Merger Agreement”), the Company notified The Nasdaq Stock Market, LLC (“Nasdaq”) of its intent to withdraw the listing of the Company’s American Depositary Shares (the “ADSs”) from Nasdaq following the effectiveness of the Scheme and requested Nasdaq file a Notification of Removal from Listing and/or Registration on Form 25 with the Securities and Exchange Commission (the “SEC”) to delist the ADSs from Nasdaq and deregister the ADSs under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Upon effectiveness of the Form 25, the Company intends to file with the SEC a Form 15 under the Exchange Act, requesting the deregistration of the ADSs and the suspension of the Company’s reporting obligations under Sections 13 and 15(d) of the Exchange Act. Trading of the ADSs on Nasdaq is expected to halt prior to the opening of trading on September 3, 2026. Following the completion of the transactions contemplated by the Merger Agreement, Topco will be renamed “Clywedog Therapeutics Holdings, Inc.,” and its common stock will be listed on Nasdaq under the ticker symbol “CLYD.”
Item 7.01. Regulation FD Disclosure.
On August 24, 2026, the Company issued a press release titled “Barinthus Bio Provides Update on Proposed Combination with Clywedog Therapeutics.” A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
The information in Item 7.01 of this Current Report on Form 8-K (including Exhibit 99.1) is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any filing by the Company under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.
Item 8.01. Other Events.
On August 24, 2026, pursuant to the terms of the Merger Agreement, the board of directors of the Company (the “Board”) determined that the Scheme Exchange Ratio (as defined in the Merger Agreement) is 0.111, which ensures that the price of the shares of Topco's common stock to be issued in exchange for the Scheme Shares (as defined in the Merger Agreement) would be sufficient to satisfy the minimum price requirement appliable to the listing of Topco's common stock on Nasdaq.
The Merger Exchange Ratio (as defined in the Merger Agreement) will be determined as of immediately prior to the closing of the merger based on the Scheme Exchange Ratio as finally determined by the Board, any adjustments as provided in the Merger Agreement and to maintain the agreed ownership split of Topco following closing of the transaction.
The Company’s application in respect of the transactions contemplated within the Merger Agreement is directed to be heard before a High Court Judge at the Royal Courts of Justice, The Rolls Building, 7 Rolls Building, Fetter Lane, London, United Kingdom, EC4A 1NL on September 1, 2026.
