Dear Sir/ Madam,

Re: XIAO-I CORPORATION (the “Company”)

We have acted as special legal counsel in the Cayman Islands to the Company in connection with a registration statement on Form F-3 (the “Registration Statement”, which term does not include any other document or agreement whether or not specifically referred to therein or attached as an exhibit or schedule thereto), filed with the U.S. Securities and Exchange Commission (the "Commission") on or about the date hereof under the U.S. Securities Act of 1933, as amended, (the "Securities Act") relating to securities to be issued and sold by the Company from time to time, and the prospectus supplement to the Registration Statement (the “Prospectus Supplement”, together with the prospectus included in the Registration Statement, the “Prospectus”) through which the Company may offer up to US$100,000,000 American Depository Shares (“ADSs”) and each ADS represents one-third of one ordinary share of par value US$0.00005 (the “ Shares”).

1. DOCUMENTS REVIEWED

For the purposes of giving this opinion, we have examined copies of the following documents:

1.1. the Registration Statement; and

1.2. the Prospectus;

We have also reviewed copies of:

1.3. the amended and restated memorandum and articles of association of the Company each certified by a director of the Company on 9 May 2024 (the “Amended M&A”);

Partners: Piers J. Alexander, Christopher W. H. Bickley, Peter H. Y. Ch’ng, Anna W. T. Chong, Angie Y. Y. Chu, Vivien C. S. Fung, Richard J. Hall, Norman Hau, Wynne Lau, Paul M. L. Lim, Anna W. X. Lin, Ryan A. McConvey, Teresa F. Tsai, Flora K. Y. Wong, Lilian S. C. Woo, Mark P. Yeadon

BERMUDA | BRITISH VIRGIN ISLANDS | CAYMAN ISLANDS

1.4. the written resolutions of the directors of the Company dated 8 May 2024 (the “Resolutions”);

1.5. a Certificate of Good Standing issued by the Registrar of Companies in relation to the Company on 7 May 2024 (the “Certificate Date”); and

1.6. such other documents and made such enquiries as to questions of law as we have deemed necessary in order to render the opinion set forth below.

2. ASSUMPTIONS

We have assumed:

2.1. the genuineness and authenticity of all signatures and the conformity to the originals of all copies (whether or not certified) examined by us and the authenticity and completeness of the originals from which such copies were taken;

2.2. that where a document has been examined by us in draft form, it will be or has been executed and/or filed in the form of that draft, and where a number of drafts of a document have been examined by us all changes thereto have been marked or otherwise drawn to our attention;

2.3. the accuracy and completeness of all factual representations made in the Registration Statement, the Prospectus and other documents reviewed by us;

2.4. that the Resolutions were passed at one or more duly convened, constituted and quorate meetings or by unanimous written resolutions, remain in full force and effect and have not been rescinded or amended;

2.5. that there is no provision of the law of any jurisdiction, other than the Cayman Islands, which would have any implication in relation to the opinions expressed herein;

2.6. that upon the issue of any Shares to be sold by the Company, the Company will receive consideration for the full issue price thereof which shall be equal to at least the par value thereof;

2.7. that the Company will have sufficient authorized and unissued share capital to effect the issue of Shares at the time of issuance;

2.8. the validity and binding effect under the laws of the United States of America of the Registration Statement and the Prospectus and that the Registration Statement and the Prospectus will be duly filed with by the Commission; and

2.9. the Company has not taken any action to appoint a restructuring officer.

3. QUALIFICATIONS

“Non-assessability” is not a legal concept under Cayman Islands law, but when we describe the Shares herein as being “non-assessable” we mean, subject to any contrary provision in any agreement between the Company and any one of its members holding any of the Shares (but only with respect to such member), that no further sums are payable with respect to the issue of such Shares and no member shall be bound by an alteration in the constitutional documents of the Company after the date upon which it became a member if and so far as the alteration requires such member to take or subscribe for additional Shares or in any way increases its liability to contribute to the share capital of, or otherwise pay money to, the Company.

We have made no investigation of and express no opinion in relation to the laws of any jurisdiction other than the Cayman Islands.  This opinion is to be governed by and construed in accordance with the laws of the Cayman Islands and is limited to and is given on the basis of the current law and practice in the Cayman Islands.

4. OPINION

On the basis of and subject to the foregoing, we are of the opinion that:-

4.1. The Company is duly incorporated and validly existing as an exempted company with limited liability under the laws of the Cayman Islands and, based on the Certificate of Good Standing, is in good standing as at the Certificate Date. Pursuant to the Companies Act (the “Act”), a company is deemed to be in good standing if all fees and penalties under the Act have been paid and the Registrar of Companies has no knowledge that the Company is in default under the Act.

4.2. Based solely on our review of the amended and restated memorandum of association of the Company, the authorised share capital of the Company is US$50,000 divided into 1,000,000,000 shares of a par value of US$0.00005 each.

4.3. The issue of the Shares has been duly authorised and, when issued and paid for in accordance with the Resolutions and the Registration Statement, the Shares will be validly issued, fully paid and non-assessable (which term when used herein means that no further sums are required to be paid by the holders thereof in connection with the issue of such Shares).

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. In giving this consent, we do not hereby admit that we are experts within the meaning of Section 11 of the Securities Act or that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Commission promulgated thereunder.

Yours faithfully,
