Item 8.01    Other Events.

        On June 16, 2020, the Registration Statement on Form S-1 (File No. 333-238824) (the "Registration Statement") relating to the initial public offering (the "IPO") of Trebia Acquisition Corp. (the "Company") was declared effective by the U.S. Securities and Exchange Commission, and the Company subsequently filed, on June 16, 2020, a registration statement on Form S-1 (File No. 333-239221) pursuant to Rule 462(b) under the Securities Act of 1933, as amended, which was effective immediately upon filing. On June 19, 2020, the Company consummated the IPO of 51,750,000 units (the "Units"), including the issuance of 6,750,000 Units as a result of the underwriters' exercise in full of their over-allotment option. Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share ("Class A Ordinary Shares"), and one-third of one redeemable warrant of the Company, each whole warrant entitling the holder thereof to purchase one Class A Ordinary Share at an exercise price of $11.50 per share. The Units were sold at a price of $10.00 per share, generating gross proceeds to the Company of $517,500,000.

        On June 16, 2020, the Company effected a stock dividend with respect to the Company's Class B ordinary shares, par value $0.0001 per share, of 2,156,250 shares thereof, resulting in the Company's initial stockholders holding an aggregate of 12,937,500 founder shares.

        Substantially concurrently with the closing of the IPO, the Company completed the private sale of 8,233,334 warrants (the "Private Placement Warrants") at a purchase price of $1.50 per Private Placement Warrant, to the Company's sponsors, BGPT Trebia LP (the "Bridgeport Sponsor") and Trasimene Trebia, LP (the "Trasimene Sponsor" and, together with the Bridgeport Sponsor, the "Sponsors"), generating gross proceeds to the Company of approximately $12,350,000. The Private Placement Warrants are identical to the warrants sold as part of the Units in the IPO, except that, so long as they are held by the Sponsors or their permitted transferees: (i) they will not be redeemable by the Company (except in certain redemption scenarios when the price per Class A Ordinary Share equals or exceeds $10.00 (as adjusted)), (ii) they (including the Class A Ordinary Shares issuable upon exercise of these warrants) may not, subject to certain limited exceptions, be transferred, assigned or sold by the Sponsors until 30 days after the completion of the Company's initial business combination, (iii) they may be exercised by the holders on a cashless basis, and (iv) they (including the Class A Ordinary Shares issuable upon exercise of these warrants) are entitled to registration rights.

        A total of $517,500,000, comprised of the proceeds from the IPO and the sale of the Private Placement Warrants, were placed in a U.S.-based trust account at JP Morgan Chase Bank, N.A., maintained by Continental Stock Transfer & Trust Company, acting as trustee. Except with respect to interest earned on the funds in the trust account that may be released to the Company to pay its taxes, if any, the proceeds from the IPO will not be released from the trust account until the earliest to occur of: (a) the completion of the Company's initial business combination, (b) the redemption of any public shares properly tendered in connection with a shareholder vote to amend the Company's amended and restated memorandum and articles of association (i) to modify the substance or timing of its obligation to redeem 100% of its public shares if the Company does not complete its initial business combination within 24 months from the closing of the IPO or (ii) with respect to any other provisions relating to shareholders' rights or pre-initial business combination activity and (c) the redemption of all of the Company's public shares if the Company has not completed its initial business combination within 24 months from the closing of the IPO, subject to applicable law.
