On January 24, 2017, SmartFinancial, Inc., a Tennessee corporation (the “Company”) and certain selling shareholders, entered into an Underwriting Agreement (the “Underwriting Agreement”) with Raymond James & Associates, Inc. as representative of the underwriters listed on Schedule I (the “Underwriters”) to the Underwriting Agreement, for the issuance and sale of 1,770,084 shares of common stock, par value $1.00 per share, of the Company (“Common Stock”), of which 170,084 shares will be sold by certain selling shareholders, for an aggregate purchase price of $34,074,117, or $19.25 per share, less underwriting discounts and commissions. Of the aggregate purchase price, SmartFinancial is expected to receive net proceeds of approximately $28,952,000, and selling shareholders are expected to receive net proceeds of approximately $3,077,670, after deducting underwriting discounts and commissions. The Company also has granted the Underwriters a 30-day option to purchase an additional 240,000 shares of Common Stock at the public offering price, less underwriting discounts solely to cover over-allotments, if any.

Pursuant to the Underwriting Agreement, the Company and its directors and executive officers have entered into 180-day “lock-up” agreements with respect to sales of shares of Common Stock, subject to customary exceptions. The form of this agreement is attached to the Underwriting Agreement.

The Underwriting Agreement contains representations, warranties and covenants customary in agreements of this type. These representations, warranties and covenants are not representations of factual information to investors about the Company or its subsidiaries, and the sale of the Common Stock in the offering is not a representation that there has not been any change in the condition of the Company. The Company also agreed to indemnify the Underwriters against certain liabilities arising out of or in connection with the sale of Common Stock in the offering.

The foregoing description of the Underwriting Agreement is not complete and is qualified in its entirety by reference to the complete text of the Underwriting Agreement, a copy of which is attached as Exhibit 1.1 to this Current Report on Form 8-K and incorporated herein by reference. Butler Snow LLP, counsel to the Company, delivered an opinion as to the validity of the shares of Common Stock, a copy of which is attached hereto as Exhibit 5.1 and is incorporated by reference herein.

The offering and sale of the Common Stock is being made pursuant to a prospectus supplement and base prospectus that was filed as a part of the Company’s Registration Statement on Form S-3 (File No. 333-214802) under the Securities Act of 1933, as amended, which registration statement was filed with the U.S. Securities and Exchange Commission and became effective on January 9, 2017. The offering is expected to close on or around January 30, 2017.

On January 25, 2017, the Company issued a press release related to the pricing of the Common Stock. A copy of the press release is attached as Exhibit 99.1 hereto.
