Of the 6,300,000 Class A shares sold in the offering, the Company sold 1,377,523 Class A shares (the “primary offering”) and a selling shareholder sold 4,922,477 Class A shares.

In addition, the Company has granted the underwriters a 30-day option to purchase up to an additional 945,000 Class A shares at the public offering price, less the underwriting discount, to cover over-allotments.
