Item 1.01 Entry into a Material Definitive Agreement

On May 31, 2017, CIT Group Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Morgan Stanley & Co. LLC and the other underwriters named on Schedule A thereto (collectively, the “Underwriters”), relating to the offer and sale in an underwritten offering of 325,000 shares of the Company’s Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series A (the “Series A Preferred Stock”). The shares of Series A Preferred Stock were sold at a public offering price of $1,000.00 per share and the Underwriters agreed to purchase the shares from the Company at a discount of $17.538 per share. Dividends on the Series A Preferred Stock will accrue and be payable from the date of issuance to, but excluding, June 15, 2022, at a rate of 5.800% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2017. From and including June 15, 2022, the Company will pay dividends on the Series A Preferred Stock, when, as, and if declared, at a floating rate equal to the then applicable three-month U.S. dollar LIBOR rate plus a spread of 3.972% per annum, payable quarterly in arrears, on March 15, June 15, September 15 and December 15 of each year, beginning on September 15, 2022. The offering is expected to close on June 7, 2017, subject to customary closing conditions.

The Company made certain customary representations, warranties and covenants in the Underwriting Agreement concerning the Company and its subsidiaries and the registration statement, prospectus, prospectus supplements and other documents and filings relating to the offering of the shares of Series A Preferred Stock. In addition, the Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The foregoing description of the Underwriting Agreement is qualified in its entirety by reference to that agreement, a copy of which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.
