Notice of Delisting and 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 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 (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.

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.”
Determination of the Scheme Exchange Ratio

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.
