SPIRIT OF TEXAS BANCSHARES, INC. ANNOUNCES FILING OF

$150 MILLION SHELF REGISTRATION STATEMENT AND

AUTHORIZATION OF A STOCK BUYBACK PROGRAM

CONROE, TEXAS — June 13, 2019 — Spirit of Texas Bancshares, Inc. (Nasdaq: STXB) (the “Company” or “Spirit”), the parent company of Spirit of Texas Bank, today announced the filing with the Securities and Exchange Commission (“SEC”) of a $150 million universal shelf registration statement on Form S-3.

The shelf registration statement permits Spirit to offer and sell, from time to time over the next three years, in one or more offerings, an indeterminate dollar amount of a variety of its securities, which may consist of common stock, preferred stock, debt securities, depositary shares, warrants or units consisting of any of the foregoing. The terms of any such offerings under the shelf registration statement will be determined at the time of the offering and will be described in detail in a prospectus supplement filed in connection with such offering.

The Company may use the shelf registration statement on an as-needed basis to raise equity capital or debt for general corporate purposes. The Company has no immediate plans to issue or sell securities pursuant to the shelf registration statement, which is intended to provide financial flexibility to access additional capital when and if needed in an expeditious manner when market conditions are appropriate.

In addition, the board of directors of Spirit (the “Board”) has authorized a stock buyback program (the “Stock Buyback Program”) pursuant to which the Company may, from time to time, purchase up to $11.7 million of its outstanding shares of common stock. The shares may be repurchased from time to time in privately negotiated transactions or the open market, including pursuant to Rule 10b5-1 trading plans, and in accordance with applicable regulations of the SEC. The timing and exact amount of any repurchases will depend on various factors including, the performance of the Company’s stock price, general market and other conditions, applicable legal requirements and other factors. The Stock Buyback Program has an expiration date of June 18, 2020. The Stock Buyback Program may be terminated or amended by the Board at any time prior to the expiration date.

The shelf registration statement relating to these securities has been filed with the SEC but has not yet become effective. The securities under the registration statement may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective.

Dean O. Bass, Spirit’s Chairman and Chief Executive Officer, stated, “We believe this shelf registration enhances the Company’s financial flexibility to access the capital markets and take advantage of strategic opportunities.

“While accretive acquisitions remain part of our strategy for capital deployment, we believe that opportunistic share repurchases should always be a consideration as part of a diversified capital allocation strategy,” added Mr. Bass.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy securities, nor shall there be any sale of any securities in any jurisdiction in which such an offer, solicitation or sale would be unlawful prior to any registration or qualification under the securities laws of such jurisdiction. Any offer of securities covered by the registration statement may be made solely by means of the written prospectus included in the registration statement and an accompanying prospectus supplement. A copy of the prospectus included in the registration statement may be obtained on the SEC’s website at www.sec.gov or from Spirit’s investor relations website.
