Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant

On March 1, 2023, Horizon Acquisition Corporation II (the “Company”) obtained a working capital loan in the total amount of $275,000 from Flint Rock Portfolio Trust, LLC (the “Lender”), an affiliate of the Company’s sponsor. The loan made by the Lender is evidenced by a promissory note (the “Note”). The Company expects to use the proceeds of the loan to fund working capital deficiencies and to finance transaction costs in connection with the Business Combination (as defined below).

The Note is an unsecured obligation of the Company. It is payable from assets of the Company other than the Company’s Trust Account (as defined in the Company’s Amended and Restated Memorandum and Articles of Association). The Note provides that the holder waives recourse to the Trust Account.

The principal balance of the Note is payable on the earlier of (i) the date on which the Company consummates its initial business combination and (ii) the date on which the Company liquidates the Trust Account upon the failure of the Company to consummate its initial business combination within the time period set forth in the Company’s Amended and Restated Memorandum and Articles of Association. Such time period currently ends on September 30, 2023.

The Note does not bear interest.

The holder of the Note has the option to convert all or any portion of the principal outstanding under such Note into warrants at a conversion price of $1.50 per warrant. However, the maximum principal amount that may be converted, as to the Note and all other notes evidencing working capital loans, is $1,500,000 or such greater dollar amount as may be agreed to by the Company, with such approvals as may be necessary or advisable. The warrants into which the Note may be converted will be substantially identical to the terms of the private placement warrants issued by the Company in connection with its initial public offering. Such terms entitle the holder of a warrant to purchase one Class A ordinary share of the Company for $11.50.

The foregoing description of the Note is qualified in its entirety by reference to the full text of the Note, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Additional Information and Where to Find It

On October 11, 2022, the Company announced the execution of a Business Combination Agreement (the “BCA”), dated as of October 11, 2022, among the Company, OTH Merger Sub 1, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Company, Flexjet, Inc., a Delaware corporation (“Flexjet”), Flexjet Sub, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Flexjet, and Epic Aero, Inc., a Delaware corporation (“Epic”). Epic Fairgrave, Inc., became a party to the BCA by joinder dated February 21, 2023. The BCA provides for the terms and conditions of a proposed business combination transaction with Epic (the “Business Combination”).

In connection with the BCA, the Company, Epic and Flexjet intend to prepare, and Flexjet intends to file a registration statement on Form S-4 (the “Registration Statement”) containing a proxy statement/prospectus and certain other related documents, which will be both the proxy statement to be distributed to holders of the Company’s ordinary shares in connection with the Company’s solicitation of proxies for the vote by the Company’s shareholders with respect to the Business Combination and other matters as may be described in the Registration Statement, as well as the prospectus relating to the offer and sale of the securities of Flexjet to be issued in connection with the Business Combination. When available, the Company will mail the definitive proxy statement/prospectus and other relevant documents to its shareholders as of a record date to be established for voting on the Business Combination. This communication is not a substitute for the Registration Statement, the definitive proxy statement/prospectus or any other document that the Company will send to its shareholders in connection with the Business Combination. Investors and security holders of the Company are advised to read, when available, the preliminary proxy statement/prospectus in connection with the Company’s solicitation of proxies for its extraordinary general meeting of shareholders to be held to approve the Business Combination (and related matters) and general amendments thereto and the definitive proxy statement/prospectus because the proxy statement/prospectus will contain important information about the Business Combination and the parties to the Business Combination.

Copies of the preliminary proxy statement/prospectus, the definitive proxy statement/prospectus and other documents filed by the Company or Flexjet with the U.S. Securities and Exchange Commission (the “SEC”) may be obtained, once available, free of charge at the SEC’s website at www.sec.gov.

Participants in the Solicitation

The Company and its directors, executive officers, other members of management, and employees, under SEC rules, may be deemed to be participants in the solicitation of proxies of the Company’s shareholders in connection with the Business Combination. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of the Company’s shareholders in connection with the Business Combination will be in the Registration Statement, including a proxy statement/prospectus, when it is filed with the SEC. Investors and security holders may obtain more detailed information regarding the names and interests in the Business Combination of the Company’s directors and officers in the Company’s filings with the SEC and such information will also be in the Registration Statement to be filed with the SEC, which will include the proxy statement/prospectus of the Company for the Business Combination. These documents can be obtained free of charge at the SEC’s website (www.sec.gov).

Flexjet, Epic and their respective directors and executive officers may also be deemed to be participants in the solicitation of proxies from the shareholders of the Company in connection with the Business Combination. A list of the names of such directors and executive officers and information regarding their interests in the proposed business combination will be included in the proxy statement/prospectus for the Business Combination when available.

Forward-Looking Statements

Certain statements made in this Current Report and the documents incorporated by reference herein are “forward looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as: “target,” “believe,” “expect,” “will,” “shall,” “may,” “anticipate,” “estimate,” “would,” “positioned,” “future,” “forecast,” “intend,” “plan,” “project,” “outlook” and other similar expressions that predict or indicate future events or trends or that are not statements of historical matters.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on the Company’s and Epic’s managements’ current beliefs, expectations and assumptions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Actual results and outcomes may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements.

The Company cautions that the foregoing list of factors is not exclusive.

The Company, Epic and Flexjet caution readers not to place undue reliance on any forward-looking statements. The Company, Epic and Flexjet do not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in their expectations or any change in events, conditions, or circumstances on which any such statement is based, whether as a result of new information, future events, or otherwise, except as may be required by applicable law. None of the Company, Epic and Flexjet gives any assurance that any of the Company, Epic or Flexjet will achieve its expectations.
