This Amendment No. 1 is being filed to amend the Registration Statement on Form F-3 (File No. 333- 292677) originally filed by the registrant on January 12, 2026 to (i) modify the amount of unsold securities to be included on the Registration Statement pursuant to Rule 415(a)(6) under the Securities Act of 1933, as amended, that were registered on a previously filed registration statement, as indicated in Exhibit 107 to this Amendment; and (ii) update the exhibit index set forth in Item 16. Accordingly, this Amendment No. 1 consists only of the facing page, this explanatory note, Part II of the Registration Statement, the signature page to the Registration Statement, and the exhibit being filed with this Amendment No. 1. The remainder of the Registration Statement, including the prospectus, is unchanged and has been omitted.

| **ITEM 8.** | **Exculpation, Insurance and Indemnification of Office Holders.** |

---

Cayman Islands law does not limit the extent to which a company's articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against willful default, willful neglect, civil fraud or the consequences of committing a crime. Our Amended and Restated Memorandum and Articles of Association (our "articles of association") permit indemnification of officers and directors for any liability, action, proceeding, claim, demand, costs damages or expenses, including legal expenses, incurred in their capacities as such unless such liability (if any) arises from actual fraud, willful neglect or willful default which may attach to such directors or officers. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we have entered into indemnification agreements with our directors and senior executive officers that provide such persons with additional indemnification beyond that provided in our articles of association.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

(a) The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933, as amended, or the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing,
any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which
was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus
filed with the Securities Exchange Commission, or the SEC, pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan
of distribution not previously disclosed in the registration statement or any material change to such information in the registration
statement;

*provided, however*, that paragraphs (a)(1)(i), (a)(1)(ii), and (a)(1)(iii) of this section do not apply if the registration statement is on Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are incorporated by reference in the registration statement, or, as to a registration statement on Form F-3, is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;(4) If the registrant is a foreign private issuer, to file a post-effective
amendment to the registration statement to include any financial statements required by Item 8.A of Form 20-F at the start of any
delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of
the Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial
statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the
prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration
statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by
Section 10(a)(3) of the Act or Item 8.A of Form 20-F if such financial statements and information are contained in periodic
reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
that are incorporated by reference in the Form F-3.

&nbsp;&nbsp;&nbsp;&nbsp;(5) That, for the purpose of determining liability under the Securities
Act to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall
be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration
statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) Each prospectus required to be filed pursuant to Rule 424(b)(2),
(b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i),
(vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed
to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness
or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for
liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective
date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the
offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement
made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed
incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser
with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement
or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

&nbsp;&nbsp;&nbsp;&nbsp;(6) That, for the purpose of determining liability of the
registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes
that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting
method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following
communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities
to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Any preliminary prospectus or prospectus of the undersigned
registrant relating to the offering required to be filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Any free writing prospectus relating to the offering prepared
by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The portion of any other free writing prospectus relating to
the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned
registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Any other communication that is an offer in the offering made
by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant
to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.

(c) Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC
such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable . In the event
that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities being registered, the registrant
will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy
as expressed in the Securities Act and will be governed by the final adjudication of such issue.

**SIGNATURES**

Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form F-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in London, United Kingdom, on January 23, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <sup>1</sup> Pursuant to Rule 415(a)(6) under the Securities Act, securities with a maximum aggregate price of $102,627,991.21 registered hereunder are unsold securities (the "Unsold Securities") previously covered by the Registrant's registration statement on Form F-3 (File No. 333-284343), which became effective on January 29, 2025 (the "Prior Registration Statement"), and are included in this registration statement. The Registrant paid a filing fee of $15,712.35 (calculated at the filing fee rate in effect at the time of the filing of the Prior Registration Statement) relating to the Unsold Securities under the Prior Registration Statement, and no additional filing fee is due with respect to the Unsold Securities in connection with the filing of this registration statement. During the grace period afforded by Rule 415(a)(5) under the Securities Act, the Registrant may continue to offer and sell under the Prior Registration Statement the Unsold Securities being registered hereunder. To the extent that, after the filing date hereof and prior to the effectiveness of this registration statement, the Registrant sells any Unsold Securities under the Prior Registration Statement, the Registrant will identify in a pre-effective amendment to this registration statement the updated number of Unsold Securities from the Prior Registration Statement to be included in this registration statement pursuant to Rule 415(a)(6) and the updated amount of new securities to be registered on this registration statement. Pursuant to Rule 415(a)(6) under the Securities Act, the offering of Unsold Securities under the Prior Registration Statement will be deemed terminated as of the date of effectiveness of this registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <sup>2</sup> There are being registered hereunder such indeterminate number of ordinary shares, debt securities, subscription rights, warrants and units as shall have an aggregate initial offering price not to exceed $250,000,000. Any securities registered hereunder may be sold separately or in combination with other securities registered hereunder. In addition, pursuant to Rule 416 under the Securities Act of 1933, as amended (the "Securities Act"), the shares being registered hereunder also include such indeterminate number of shares as may be issuable with respect to the shares being registered hereunder as a result of stock splits, stock dividends or similar transactions. The proposed maximum per unit and aggregate offering prices per class of securities will be determined from time to time by the registrant in connection with the issuance by the registrant of the securities registered hereunder and is not specified pursuant to Instruction 2.A.ii.b. to the Calculation of Filing Fee Tables and Related Disclosure on of Item 9(b) of Form F-3 under the Securities Act.
