Special Redemption:	The Company may redeem the Notes, in whole but not in part, at any time, including prior to September 15, 2024, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, if (i) an amendment or change or prospective amendment or change in law occurs, or an administrative or judicial action is announced or taken or there is an amendment to or change in any official position or interpretation with respect to, an administrative or judicial action or a law or regulation that differs from the previously generally accepted position or interpretation, in each case that, as a result of which, there is more than an insubstantial risk that interest payable by us on the Notes will not be deductible by us, in whole or in part, for United States federal income tax purposes, (ii) a subsequent event occurs that, as a result of which, there is more than an insubstantial risk that the Company would not be entitled to treat the Notes as Tier 2 capital for regulatory capital purposes, or (iii) the Company is required to register as an investment company under the Investment Company Act of 1940, as amended, in each case, at a redemption price equal to 100% of the principal amount of the Notes plus any accrued and unpaid interest to but excluding the redemption date.

The redemption of the $130.0 million of subordinated notes issued by Pinnacle Bank is subject to the Company’s receipt of all necessary regulatory permission for such redemption, which the Company has not yet sought, and the Company’s ultimate determination to redeem such notes after they become eligible for redemption.

Price to Public:	100.00%

Underwriters’ Discount:	1.00% of principal amount
Proceeds to Issuer (after underwriters’ discount, but before expenses):	$297,000,000
Ranking:	The Notes will be unsecured, subordinated obligations of the Company and: •  will rank junior in right of payment and upon the Company’s liquidation to any of its existing and all future Senior Debt, all as described under “Description of the Notes” in the preliminary prospectus supplement; •  will rank junior in right of payment and upon the Company’s liquidation to any of its existing and all of its future general creditors; •  will rank equal in right of payment and upon the Company’s liquidation with any of its existing and all of its future indebtedness the terms of which provide that such indebtedness ranks equally with the Notes; •  will rank senior in right of payment and upon the Company’s liquidation to (i) its existing junior subordinated debentures issued to the Company’s capital trust subsidiaries and (ii) any of its indebtedness the terms of which provide that such indebtedness ranks junior in right of payment to note indebtedness such as the Notes; and •  will be effectively subordinated to the Company’s future secured indebtedness to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to the existing and future indebtedness of its subsidiaries, including without limitation Pinnacle Bank’s depositors, liabilities to general and trade creditors and liabilities arising in the ordinary course of business or otherwise. As of June 30, 2019, on a consolidated basis, the Company’s liabilities totaled approximately $22.36 billion, which includes approximately $19.45 billion of deposit liabilities, approximately $2.91 billion of other borrowings, which include $1.96 billion of Federal Home Loan Bank advances, approximately $209.0 million of subordinated notes issued by the Company (or bank holding companies that have been merged with and into the Company), $130.0 million of subordinated notes issued by Pinnacle Bank and $133.0 million of trust preferred securities and accompanying junior subordinated debentures, and approximately $490.0 million of other liabilities. Except for approximately $133.0 million of junior subordinated debentures and associated trust preferred securities (which rank junior in right of payment and upon liquidation to the Notes) and approximately $209.0 million of subordinated notes (which rank equal in right of payment and upon liquidation to the Notes) issued by the Company (or bank holding companies that have been merged with and into the Company) all of these liabilities are contractually or structurally senior to the Notes. The Company also has a $75.0 million revolving credit facility with U.S. Bank, National Association which had no amounts outstanding as of June 30, 2019. Any borrowings under the revolving credit facility would rank senior to the Notes.

We expect that delivery of the Subordinated Notes will be made against payment for the Subordinated Notes on or about Settlement Date indicated above, which will be the third business day following the trade date of September 6, 2019 (this settlement cycle being referred to as “T+3”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally will be required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Subordinated Notes on any date prior to the second business day preceding the Settlement Date will be required, by virtue of the fact that the notes will initially settle in three business days (T+3), to specify alternative settlement arrangements to prevent a failed settlement and should consult their own investment advisor.
