Blank-check company Horizon Acquisition Corp. filed for an initial public offering of its securities for a proposed maximum aggregate offering price of $575.0 million, which is estimated solely for the purpose of calculating the registration fee and includes the underwriters' overallotment option.

The proposed maximum offering price per unit is $10.00, and each unit consists of one class A ordinary share and one-third of one redeemable warrant. The underwriters have a 45-day option to purchase up to an additional 7.5 million units to cover for any overallotments.

Horizon Acquisition indicated in its filing that while it may pursue an initial business combination target in any industry, it currently intends to concentrate its efforts in identifying businesses in the financial services industry, with a focus on differentiated financial services and financial services-adjacent platforms.

Horizon Acquisition plans to have its units listed on the NYSE under the symbol HZAC.U. Once the securities comprising the units begin separate trading, Horizon Acquisition expects that the class A ordinary shares and warrants will be listed on the NYSE under the symbols HZAC and HZAC WS, respectively.

The blank-check company's sponsor, Horizon Sponsor LLC, has committed to purchase an aggregate of 8 million warrants, or 9 million warrants if the overallotment option if fully exercised, at a price of  $1.50 per warrant, in a private placement that will close simultaneously with the closing of the IPO. The sponsor has also indicated that it or one of its affiliates has an interest in purchasing, directly or indirectly, up to 15.5 million units at the public offering price.

Horizon Sponsor is an affiliate of investment firm Eldridge Industries LLC. Credit Suisse Securities (USA) LLC and RBC Capital Markets LLC were listed as underwriters.
