Item 8.01 Other Events

As previously disclosed, on April 21, 2021, Horizon Acquisition Corporation, a Cayman Islands exempted company (“Horizon”), entered into a Transaction Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Transaction Agreement”), by and among Horizon, Horizon Sponsor, LLC, a Delaware limited liability company (“Sponsor”), Hoya Topco, LLC, a Delaware limited liability company (“Hoya Topco”), Hoya Intermediate, LLC, a Delaware limited liability company (“Hoya Intermediate”), and Vivid Seats Inc., a Delaware corporation (“Vivid Seats”). A copy of the Transaction Agreement was attached as Exhibit 2.1 to Horizon’s Current Report on Form 8-K, filed with the Securities and Exchange Commission (“SEC”) on April 22, 2021, as amended on April 26, 2021.

Following the entry into the Transaction Agreement, Horizon received four letters (collectively, the “Shareholder Letters”) from purported shareholders of Horizon claiming certain allegedly material omissions in its preliminary proxy statement/prospectus first filed on May 28, 2021 (as amended, the “Proxy Statement”) in connection with the transactions contemplated by the Transaction Agreement (together, the “Business Combination”).

While Horizon believes that the disclosures set forth in the Proxy Statement comply fully with applicable law, in order to moot the plaintiff’s disclosure claims in the Shareholder Letters, to avoid nuisance, cost and distraction, and to preclude any efforts to delay the closing of the Business Combination, Horizon has determined to voluntarily supplement the Proxy Statement with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Horizon specifically denies all allegations in the Shareholder Letters that any additional disclosure was or is required. Horizon believes the Shareholder Letters are without merit.

Supplemental Disclosures to Proxy Statement

The following supplemental information should be read in conjunction with the Proxy Statement, which should be read in its entirety. All page references are to pages in the Proxy Statement, and terms used below, unless otherwise defined, have the meanings set forth in the Proxy Statement.

The following disclosure should be added to the end of the second full paragraph on page 106 of the Proxy Statement under the heading “Background of the Business Combination”:

Horizon entered into one confidentiality agreement that contained a standstill provision. Such confidentiality agreement was not with Vivid Seats.

The following disclosure should be added to the end of the sixth paragraph on page 113 of the Proxy Statement under the heading “Background of the Business Combination”:

Pursuant to an engagement letter (the “Advisors Engagement Letter”) with Credit Suisse and Deutsche Bank (together with Credit Suisse, the “Advisors”), Credit Suisse and Deutsche Bank will act as Horizon’s financial and equity capital markets advisors and will perform customary services for Horizon in connection with the business combination. Pursuant to the Advisors Engagement Letter, upon consummation of the business combination, Horizon and the Advisors shall agree on a mutually acceptable transaction fee.

The following disclosure should be added as new paragraphs after the seventh paragraph on page 113 of the Proxy Statement under the heading “Background of the Business Combination”:

On May 20, 2021, Horizon entered into an engagement letter with D.A. Davidson & Co. (“D.A. Davidson”), pursuant to which D.A. Davidson will render financial advisory and investment banking services to Horizon in connection with the business combination (the “Davidson Engagement Letter”). Pursuant to the Davidson Engagement Letter, upon consummation of the business combination, Horizon will owe D.A. Davidson a cash advisory fee of $400,000 (which shall be a portion of the Deferred Discount (as defined in the underwriting agreement)).

On May 24, 2021, Horizon entered into an engagement letter with William Blair & Company, L.L.C. (“Blair”), pursuant to which Blair will act as a capital markets advisor to Horizon in connection with the business combination (the “Blair Engagement Letter”). Pursuant to the Blair Engagement Letter, upon consummation of the business combination, Horizon will owe Blair an advisory fee of $1,500,000 (which shall be a portion of the Deferred Discount).

General Meeting Dial-in Information

As previously announced, the extraordinary general meeting of Horizon shareholders (the “General Meeting”) will be held on October 14, 2021 at 10:00 a.m., New York City Time, and the special meeting of Horizon public warrant holders (the “Warrant Holders Meeting”) will be held on October 14, 2021 at 10:15 a.m., New York City Time. On October 7, 2021, Horizon determined that, due to the public health and safety concerns related to the ongoing coronavirus (COVID-19) pandemic, the General Meeting and the Warrant Holders Meeting will be held remotely by teleconference. The purpose of the General Meeting and the Warrant Holders Meeting is to vote on certain proposals relating to the previously announced Transaction Agreement.

The General Meeting and the Warrant Holders Meeting will be accessible via a live audio webcast at https://www.cstproxy.com/horizonacquisitioncorp/sm2021 or by dialing 1 877-770-3647 (toll free—North America) or +1 312-780-0854 (International). Shareholders and public warrant holders will be able to submit a question to Horizon’s management online in advance of the meeting at the following website, https://www.cstproxy.com/horizonacquisitioncorp/sm2021, or live during each respective meeting.

All information about the General Meeting and the Warrant Holders Meeting, including the definitive proxy statement/prospectus, is available at https://www.cstproxy.com/horizonacquisitioncorp/sm2021.

Shareholders of Horizon and other interested persons are encouraged to read the definitive proxy statement/prospectus, as well as the annexes thereto and the other documents to be filed with the SEC because these documents contain important information about Horizon, Vivid Seats and the Business Combination. Shareholders are able to obtain copies of the definitive proxy statement/prospectus and other documents filed with the SEC, without charge, at the SEC’s website (www.sec.gov) under “Horizon Acquisition Corporation” (CIK: 0001817071).

After the Registration Statement was declared effective, the definitive proxy statement/prospectus was mailed to shareholders of Horizon as of September 7, 2021, the record date established for voting on the Business Combination.
