Re: Registration Statement on Form S-4 (File No. 333-274502)

Ladies and Gentlemen:

We have acted as counsel to Pono Capital Three, Inc., a Cayman Islands exempted company (“Pono”) in connection with the continuation of Pono from the Cayman Islands to the Province of British Columbia, Canada (the “SPAC Continuance”), and the proposed amalgamation (the “Amalgamation”) of Pono Three Merger Acquisitions Corp., a British Columbia company (“Merger Sub”) and wholly-owned subsidiary of Pono, with Robinson Aircraft Ltd., a British Columbia company d/b/a Horizon Aircraft (“Horizon”), as contemplated by the business combination agreement, dated as of August 15, 2023, by and among Pono, Merger Sub, and Horizon (the “Business Combination Agreement”). The time at which the Amalgamation becomes effective is hereafter referred to as the “Effective Time”. This opinion is being rendered to you in connection with the Registration Statement on Form S-4 (as amended through the date hereof, the “Registration Statement”) initially filed by Pono on September 13, 2023, including the proxy statement/prospectus forming a part thereof (the “Proxy Statement/Prospectus”), relating to the transactions contemplated by the Business Combination Agreement. For purposes of this opinion, capitalized terms used and not otherwise defined shall have the meaning ascribed thereto in the Business Combination Agreement.

You have requested our opinion concerning the tax consequences of the SPAC Continuance and the transactions described in the Business Combination Agreement and the discussion of the Business Combination as set forth in the section entitled “United States Federal Income Tax Considerations applicable to the SPAC Continuance, the Adoption of the Post-Continuance Pono Articles, the Redemptions and the Business Combination” in the Registration Statement.

Opinions

Based upon and subject to the foregoing, and subject to the limitations and qualifications set forth herein and in the Registration Statement, it is our opinion that the SPAC Continuance will qualify as a reorganization under Section 368(a)(1)(F) (an “F Reorganization”) of the Code. We further confirm that the statements set forth in the Registration Statement under the section entitled “Certain Material U.S. Federal Income Tax Considerations of the Redemption” insofar as they address the material U.S. federal income tax considerations with respect to the Merger, and discuss matters of U.S. federal income tax law and regulations or legal conclusions with respect thereto, and except to the extent stated otherwise therein, are our opinion, subject to the assumptions, qualifications, and limitations stated herein and therein.

We hereby consent to be named in the Registration Statement and to the filing of a copy of this opinion as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, and the rules and regulations of the Commission promulgated thereunder. This opinion speaks as of its date, and we undertake no (and hereby disclaim any) obligation to update this opinion.

We express our opinion herein only as to those matters specifically set forth above and no opinion should be inferred as to the tax consequences of the Business Combination under any state, local or foreign law, or with respect to other areas of U.S. federal taxation. We do not express any opinion herein concerning any law other than the federal law of the United States.

Very truly yours,
