Dear Sirs

Re: Gorilla Technology Group Inc.

We have acted as Cayman Islands legal advisers to Gorilla Technology Group Inc. (the “Company”) in connection with the Company’s registration statement on Form F-3 (the “Additional Registration Statement”) filed pursuant to Rule 462(b) under the Act (as defined below), including all amendments or supplements thereto, filed with the United States Securities and Exchange Commission (the “Commission”) under the United States Securities Act of 1933 (the “Act”), as amended, which is related to, and incorporates by reference, the Company’s registration statement on Form F-3 (File No. 333-274053), initially filed on 17 August 2023 (the “Registration Statement”), relating to the registration of certain securities up to a maximum aggregate offering price of US$300,000,000, including the Company’s (i) ordinary shares (the “Ordinary Shares”) and (ii) preferred shares (the “Preference Shares” together with the Ordinary Shares, the “Shares”).

The Additional Registration Statement relates to the registration of additional securities up to a maximum aggregate offering price of US$17,903,178, including the Company’s (i) Ordinary Shares (the “Additional Ordinary Shares”) and (ii) Preference Shares (the “Additional Preference Shares” together with the Additional Ordinary Shares, the “Additional Shares”) in addition to the Shares registered in the Registration Statement.

This opinion is given in accordance with the terms of the Legal Matters section of the Registration Statement.

1	Documents Reviewed

For the purposes of this opinion we have reviewed originals, copies, drafts or conformed copies of the documents listed in Schedule 1 to this opinion, being all of the documents necessary to form our opinion. Defined terms shall have the meanings set out in Schedule 1 or in the Registration Statement.

2	Assumptions

The following opinions are given only as to and based on circumstances and matters of fact existing at the date hereof and as to the laws of the Cayman Islands as the same are in force at the date hereof. In giving this opinion, we have assumed that copy documents or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals.

3	Opinions

Based upon, and subject to, the foregoing assumptions, and having regard to such legal considerations as we deem relevant, we are of the opinion that:

3.1	the Company has been duly incorporated and is validly existing under the laws of the Cayman Islands;

3.2

when the directors of the Company (the “Directors”) have taken all necessary corporate action to approve the issuance and establish the terms of the Additional Preference Shares, the offering thereof and related matters, and when such Additional Preference Shares and Additional Ordinary Shares have been issued and sold by the Company in the manner contemplated by the Registration Statement and in accordance with such resolutions of the Directors, such Additional Shares (including any shares of such series of preferred shares duly issued upon conversion, exchange or exercise of any other security in accordance with the terms of such other security or the instrument governing such other security providing for such conversion, exchange or exercise as approved by the Directors in accordance with the provisions of the M&A) will be duly authorized, legally issued and allotted, as fully paid and non-assessable;

3.3

in this opinion the phrase “non-assessable” means, with respect to shares in the Company, that a shareholder shall not, solely by virtue of its status as a shareholder, be liable for additional assessments or calls on the shares by the Company or its creditors (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil); and

3.4	the statements in the prospectus forming part of the Registration Statement, to the extent that they constitute statements of Cayman Islands law, are accurate in all material respects and such statements constitute our opinion.

We hereby consent to the prospectus discussion of this opinion, to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the heading “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In providing our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the Rules and Regulations of the Commission thereunder.

This opinion is limited to the matters detailed herein and is not to be read as an opinion with respect to any other matter.

Yours faithfully
