Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On November 14, 2022, Horizon Acquisition Corporation II (the “Company”) received an e-mail from the New York Stock Exchange (the “NYSE”) stating that the NYSE was assessing the Company’s ability to meet the requirements of Section 802.01B of the NYSE’s Listed Company Manual. That Section requires a listed acquisition company to maintain an average aggregate global market capitalization attributable to its publicly held shares (a “public float”) over a consecutive 30 trading day period of at least $40,000,000. The e-mail referred to the redemptions of the Company’s Class A ordinary shares in connection with the recent extension of the deadline by which the Company must complete its initial business combination to September 30, 2023. The e-mail states that the Company’s public float appears to have fallen below the NYSE’s standard required by Section 802.01B.

The e-mail states that if the Company fails to comply with the NYSE’s continued listing standards, the NYSE expects that trading in the Company’s Class A ordinary shares, warrants and units would be suspended and de-listing proceedings would be commenced on November 28, 2022.

The Company is currently evaluating possible alternatives in light of that e-mail and has had a preliminary discussion with the NYSE in which the NYSE confirmed the foregoing timetable. Based on that discussion, the Company is currently focused primarily on the possibility of transitioning its listing to the NYSE American, which is part of the NYSE group of exchanges.

The listing standards of the NYSE American include a lower public float standard than that of the NYSE ($20,000,000 instead of $40,000,000). As part of satisfying the NYSE American listing standards, the Company believes that its sponsor, Horizon II Sponsor, LLC, would need to sell a small portion of the Class A ordinary shares owned by it to third parties. The Company and its sponsor are engaged in discussions with bankers and potential third party buyers relating to this alternative, and the Company intends to apply for a listing on the NYSE American on this basis.

There can be no assurance that the Company will be able to obtain an alternative listing on the NYSE American or otherwise or that the transition from the NYSE to the NYSE American, if it can be effected, can be effected without a time gap in being listed.

The foregoing actions and their consequences could affect the liquidity and value of the Company’s securities.
