BancShares and are neither obligations of, nor guaranteed by, First Citizens Bank or any of our other subsidiaries. The Notes are not savings accounts, deposits or other obligations of First Citizens Bank or any of our other subsidiaries and are not
insured or guaranteed by the FDIC or any other governmental agency or public or private insurer. We may issue additional series of notes under the Subordinated Indenture. See “—Further Issues.” The following description of the
Notes may not be complete and is subject to and qualified in its entirety by reference to the Subordinated Indenture.

The Notes will
mature on , 20 (the “Maturity Date”), unless previously redeemed or otherwise accelerated. Payment of principal on the Notes may be accelerated only upon the occurrence of specified events. See
“—Events of Default; Notices of Default.”

The Notes are not convertible into, or exchangeable for, equity securities,
other securities, or assets of BancShares or its subsidiaries. There is no sinking fund for the Notes. Except as described under “—Clearance and Settlement,” the Notes will be represented by one or more global certificates
deposited with or on behalf of DTC and registered in the name of Cede & Co. or another nominee of DTC. The Notes will be issued and may be transferred only in minimum denominations of $2,000 and integral multiples of $1,000 in excess
thereof in book-entry form only. See “—Clearance and Settlement.”

As a bank holding company, our ability to make
payments on the Notes will depend primarily on the receipt of interest and other distributions from First Citizens Bank. There
