("Vivid Seats") for use by Vivid Seats and Horizon in connection with their proposed business combination and the offering of the securities of the post-business combination company in a private placement (the "Transaction"). This presentation is for information purposes only and is being provided to you solely in your capacity as a potential investor in considering an investment in Vivid Seats. Any reproduction or distribution of this presentation, in whole or in part, or the disclosure of its contents, without the prior consent of Horizon or Vivid Seats is prohibited.

This communication is restricted by law; it is not intended for distribution to, or use by any person in, any jurisdiction where such distribution or use would be contrary to local law or regulation. No Representations and Warranties This presentation is for informational purposes only and does not purport to contain all of the information that may be required to evaluate a possible investment decision with respect to Vivid Seats. The recipient agrees and acknowledges that this presentation is not intended to form the basis of any investment decision by the recipient and does not constitute investment, tax or legal advice.

The recipient also acknowledges and agrees that the information contained in this presentation is preliminary in nature and is subject to change, and any such changes may be material. Horizon and Vivid Seats disclaim any duty to update the information contained in this presentation. Forward-Looking Statements This presentation includes "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Horizon's and Vivid Seats' actual results may differ from their expectations, estimates and projections and consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as "expect", "estimate", "project", "budget", "forecast", "anticipate", "intend", "plan", "may", "will", "could", "should", "believes", "predicts", "potential", "continue", and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, Horizon's and Vivid Seats' expectations with respect to future performance and anticipated financial impacts of the Transaction, the satisfaction of closing conditions to the Transaction and the timing of the completion of the Transaction. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. You should carefully consider the risks and uncertainties described in the "Risk Factors" section of Horizon's registration statement on Form S-1. In addition, there will be risks and uncertainties described in the proxy statement/prospectus on Form S-4 relating to the Transaction, which is expected to be filed by Vivid Seats with the Securities and Exchange Commission (the "SEC") and other documents filed by Horizon from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward looking statements. Most of these factors are outside Horizon's and Vivid Seats' control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the outcome of any legal proceedings that may be instituted against Horizon or Vivid Seats following the announcement of the Transaction; (2) the inability to complete the Transaction, including due to the inability to concurrently close the business combination and the private placement of common stock or due to failure to obtain approval of the stockholders of Horizon; (3) delays in obtaining, adverse conditions contained in, or the inability to obtain necessary regulatory approvals or complete regulatory reviews required to complete the Transaction; (4) the risk that the Transaction disrupts current plans and operations as a result of the announcement and consummation of the Transaction; (5) the inability to recognize the anticipated benefits of the Transaction, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain key employees; (6) costs related to the Transaction; (7) changes in the applicable laws or regulations; (8) the possibility that the combined company may be adversely affected by other economic, business, and/or competitive factors; (9) the impact of the global COVID-19 pandemic; and (10) other risks and uncertainties indicated from time to time described in Horizon's registration on Form S-1, including those under "Risk Factors" therein, and in Horizon's other filings with the SEC. Horizon and Vivid Seats caution that the foregoing list of factors is not exclusive and not to place undue reliance upon any forward-looking statements, including projections, which speak only as of the date made. Neither Horizon nor Vivid Seats undertakes or accepts any obligation to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based. Industry and Market Data In this presentation, Horizon and Vivid Seats rely on and refer to publicly available information and statistics regarding market participants in the sectors in which Vivid Seats competes and other industry data. Any comparison of Vivid Seats to the industry or to any of its competitors is based on this publicly available information and statistics and such comparisons assume the reliability of the information available to Vivid Seats. Vivid Seats obtained this information and statistics from third-party sources, including reports by market research firms and company filings. While Vivid Seats believes such third-party information is reliable, there can be no assurance as to the accuracy or completeness of the indicated information. Neither Vivid Seats nor Horizon has independently verified the information provided by the third-party sources. Trademarks This presentation may contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this presentation may be listed without the TM, SMO or ® symbols, but Horizon and Vivid Seats will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights. VIVIDSEATS. 2#3Disclaimer (cont'd) Private Placement The securities to which this presentation relates have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or the securities laws of any other jurisdiction. This presentation relates to securities that Vivid Seats intends to offer in reliance on exemptions from the registration requirements of the Securities Act and other applicable laws. These exemptions apply to offers and sales of securities that do not involve a public offering. The securities have not been approved or recommended by any federal, state or foreign securities authorities, nor have any of these authorities passed upon the merits of this offering or determined that this presentation is accurate or complete. Any representation to the contrary is a criminal offense. Financial and Other Information This presentation contains certain estimated preliminary financial results and key operating metrics for the year ended December 31, 2020, and the historical financial information respecting Vivid Seats contained in this presentation has been taken from or prepared based on historical financial statements of Vivid Seats, including unaudited financial statements for its fiscal year ended December 31, 2020. This information is preliminary and subject to change. As such, actual results may differ from the estimated preliminary results presented here and will not be finalized until year-end accounting procedures are completed. This presentation includes certain non-GAAP financial measures (including on a forward-looking basis) such as EBITDA, EBITDA Margin, Adjusted EBITDA and Free Cash Flow. These non-GAAP measures are an addition, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP. Vivid Seats believes that these non-GAAP measures of financial results (including on a forward-looking basis) provide useful supplemental information to investors about Vivid Seats. Vivid Seats' management uses forward-looking non-GAAP measures to evaluate Vivid Seats' projected financials and operating performance. However, there are a number of limitations related to the use of these non-GAAP measures and their nearest GAAP equivalents, including that they exclude significant expenses that are required by GAAP to be recorded in Vivid Seats' financial measures. In addition, other companies may calculate non-GAAP measures differently, or may use other measures to calculate their financial performance, and therefore, Vivid Seats' non-GAAP measures may not be directly comparable to similarly titled measures of other companies. Additionally, to the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non- GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. Use of Projections This presentation also contains certain financial forecasts, including projected revenue. Neither Horizon's nor Vivid Seats' independent auditors have studied, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect there to for the purpose of this presentation. These projections are for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. In this presentation, certain of the above-mentioned projected information has been provided for purposes of providing comparisons with historical data. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Projections are inherently uncertain due to a number of factors outside of Horizon's or Vivid Seats' control. While all financial projections, estimates and targets are necessarily speculative, Horizon and Vivid Seats believe that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection, estimate or target extends from the date of preparation. Accordingly, there can be no assurance that the prospective results are indicative of future performance of the combined company after the Transaction or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. Participation in Solicitation Horizon and Vivid Seats and their respective directors and executive officers, under SEC rules, may be deemed to be participants in the solicitation of proxies of Horizon's shareholders in connection with the proposed Transaction. Investors and security holders may obtain more detailed information regarding the names and interests in the proposed Transaction of Horizon's directors and officers in Horizon's filings with the SEC, including Horizon's registration statement on Form S-1, which was originally filed with the SEC on August 3, 2020. To the extent that holdings of Horizon's securities have changed from the amounts reported in Horizon's registration statement on Form S-1, such changes have been or will be reflected on Statements of Change in Ownership on Form S-4 filed with the SEC. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of proxies to Horizon's shareholders in connection with the proposed Transaction will be set forth in the proxy statement/prospectus on Form S-4 for the proposed Transaction, which is expected to be filed by Vivid Seats with the SEC. Investors and security holders of Horizon and Vivid Seats are urged to read the proxy statement/prospectus and other relevant documents that will be filed with the SEC carefully and in their entirety when they become available because they will contain important information about the proposed Transaction. Investors and security holders will be able to obtain free copies of the proxy statement and other documents containing important information about Horizon and Vivid Seats through the website maintained by the SEC at www.sec.gov. Copies of the documents filed with the SEC by Horizon can be obtained free of charge by directing a written request to Horizon Acquisition Corporation, 600 Steamboat Road, Suite 200, Greenwich, CT 06830.
