| Item 1.01 |
Entry into a Material Definitive Agreement. |
Amendment to the Merger Agreement
As previously disclosed, on September 29,
2025, Barinthus Biotherapeutics plc, a public limited company organized under the laws of England and Wales (“Beacon”),
entered into an Agreement and Plan of Merger (the “Original Merger Agreement”) by and among Beacon, Beacon Topco, Inc.,
a Delaware corporation and a direct wholly owned subsidiary of Beacon (“Topco”), Cdog Merger Sub, Inc., a Delaware
corporation and a direct wholly owned subsidiary of Topco (“Merger Sub”), and Clywedog Therapeutics, Inc., a Delaware
corporation (“Clywedog”).
The Original Merger Agreement provides that, among
other things, upon the terms and subject to the conditions set forth therein (i) Topco will acquire the entire issued and to be issued
share capital of Beacon pursuant to a scheme of arrangement (subject to any modification, addition or condition which (a) Beacon,
Topco and Clywedog mutually agree and which (if required) is approved by the High Court of Justice of England and Wales (the “Court”)
or (b) is otherwise imposed by the Court and mutually acceptable to Beacon, Topco and Clywedog, each acting reasonably and in good
faith, in each case in accordance with the Part 26 of the United Kingdom Companies Act 2006 and the Merger Agreement (the “Scheme
of Arrangement” and such transaction, the “Scheme Transaction”)) and (ii) Merger Sub will merge with
and into Clywedog, with Clywedog continuing as the surviving corporation and a direct wholly owned subsidiary of Topco in accordance with
the Delaware General Corporations Law (together with the Scheme Transaction, the “Combinations”).
On February 22, 2026, the Beacon,
Topco, Merger Sub and Clywedog entered into the Amendment to the Agreement and Plan of Merger (the “Merger Agreement Amendment”
and the Original Merger Agreement, as amended by the Merger Agreement Amendment, the “Merger Agreement”). Pursuant
to the Merger Agreement Amendment, (i) the definition of “Scheme Exchange Ratio” as set forth in Section 1.1 of
the Original Merger Agreement was amended and replaced in its entirety to mean a number between 0.1 and 0.166667, as finally determined
by the Board of Directors of Beacon (or a duly appointed committee thereof), (ii) the definition of “Merger Exchange Ratio”
as set forth in Section 1.1 of the Original Merger Agreement was amended and replaced in its entirety to mean a number between 0.000305
and 0.000508, as finally determined by Clywedog and Beacon in accordance with Section 2.6(d) of the Merger Agreement and correspondingly
based on the change to the Scheme Exchange Ratio, in order to maintain the agreed ownership split of Topco following closing of the Combinations,
and (iii) the Clywedog Minimum Cash and Beacon Minimum Cash (each as defined in the Merger Agreement) requirements as set forth in
Section 8.9 and 9.6 of the Merger Agreement, respectively, are expanded to include required minimum cash amounts based
on an assumed closing date of May 31, 2026 and June 30, 2026, respectively, in light of the unexpected delay in the overall
transaction timeline due to the U.S. federal government shutdowns. The foregoing description of the Merger Agreement Amendment
is subject to and qualified in its entirety by reference to the full text of the Merger Agreement Amendment, a copy of which is included
as Exhibit 2.1 hereto, and the terms of which are incorporated herein by reference.
Additional Information and Where to Find It.
In connection with the proposed transaction, Topco
filed with the SEC a registration statement to register the common stock, $0.0001 par value per share, of Topco (“Topco Common
Stock”) to be issued in connection with the Combinations (the “Registration Statement”). The Registration
Statement includes a proxy statement/prospectus which will be mailed or otherwise provided to Beacon’s investors and security holders
of Topco Common Stock. BEACON’S INVESTORS AND SECURITY HOLDERS ARE URGED TO CAREFULLY READ THE REGISTRATION STATEMENT AND THE RELATED
PROXY STATEMENT/PROSPECTUS, AS WELL AS ANY AMENDMENT OR SUPPLEMENTS TO THOSE DOCUMENTS IN THEIR ENTIRETY AND ANY OTHER DOCUMENTS FILED
BY BEACON WITH THE SEC IN CONNECTION WITH THE PROPOSED TRANSACTION OR INCORPORATED BY REFERENCE THEREIN BECAUSE THEY WILL CONTAIN IMPORTANT
INFORMATION ABOUT THE PROPOSED TRANSACTION AND THE PARTIES TO THE PROPOSED TRANSACTION.
Investors and security holders may obtain a free
copy of the Registration Statement and other documents that Topco files with the SEC (when available) from the SEC’s website at
www.sec.gov or at investors.barinthusbio.com.
Participants in the Solicitation.
Clywedog, Beacon and their respective directors,
executive officers, other members of management, certain employees and other persons may be deemed to be participants in the solicitation
of proxies from the security holders of Beacon in connection with the proposed transaction. Security holders may obtain information regarding
the names, affiliations and interests of Beacon’s directors and executive officers in Beacon’s Annual Report on Form 10-K
for the fiscal year ended December 31, 2024, which was filed with the SEC on March 20, 2025, and Beacon’s definitive proxy
statement on Schedule 14A for its 2025 annual meeting of stockholders, which was filed with the SEC on April 25, 2025. To the extent
holdings of Beacon’s securities by Beacon’s directors and executive officers have changed since the amounts set forth in such
Annual Report on Form 10-K, such changes have been or will be reflected on subsequent Statements of Changes in Beneficial Ownership
on Form 4 filed with the SEC. Additional information regarding the interests of such individuals in the proposed transaction will
be included in the Registration Statement relating to the proposed transaction when it is filed with the SEC. These documents (when available)
may be obtained free of charge from the SEC’s website at www.sec.gov and Beacon’s website at investors.barinthusbio.com.
No Offer or Solicitation.
This communication is not intended to and shall
not constitute an offer to buy or sell or the solicitation of an offer to buy or sell any securities, nor shall there be any offer, solicitation
or sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification
under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the
requirements of Section 10 of the Securities Act of 1933, as amended, and otherwise in accordance with applicable law.

or Beacon’s ability to pursue certain business opportunities or strategic transactions; (xi) the risk that Clywedog or Beacon
may be unable to obtain governmental and regulatory approvals required for the proposed transaction, or that required governmental and
regulatory approvals may delay the consummation of the proposed transaction or result in the imposition of conditions that could reduce
the anticipated benefits of the proposed transaction or cause the parties to abandon the proposed transaction; (xii) the risk that
the anticipated benefits of the proposed transaction may otherwise not be fully realized or may take longer to realize than expected;
(xiii) the impact of legislative, regulatory, economic, competitive and technological changes; (xiv) risks relating to the value
of Topco securities to be issued in the proposed transaction; (xv) the risk that integration of the proposed transaction post-closing

rapidly growing and evolving; (xxi) uncertainties in contractual relationships, including collaborations, partnerships, licensing
or other arrangements and the performance of third-party suppliers and manufacturers; (xxii) the ability of each of Clywedog and
Beacon to establish and maintain intellectual property protection for their respective product candidates and products or avoid or defend
claims of infringement; (xxiii) exposure to inflation, currency rate and interest rate fluctuations and risks associated with doing
business locally and internationally, as well as fluctuations in the market price of the ADSs of Beacon; (xxiv) risks relating to
competition within the industry in which each of Clywedog and Beacon operates; (xxv) the unpredictability and severity of catastrophic
events, including, but not limited to, acts of terrorism or outbreak of war or hostilities; (xxvi) whether the termination of any
of Clywedog’s or Beacon’s license agreements and/or collaboration agreements may impact Topco’s ability to license in
additional programs in the future and the risk of delays or unforeseen costs in terminating such arrangements; and (xxvii) Clywedog’s
and Beacon’s response to any of the aforementioned factors. Additional factors that may affect the future results of Beacon are
