SCHEDULE TO

This Amendment No. 1 amends and supplements the Tender Offer Statement on Schedule TO originally filed with the United States Securities and Exchange Commission by Triumph Bancorp, Inc., a Texas corporation (the “Company”), on November 7, 2022 (together with all subsequent amendments and supplements thereto, the “Schedule TO”), in connection with the Company’s offer to purchase for cash up to $100,000,000 of its common stock, $0.01 par value per share, at a price per share of not less than $51.00 and not more than $58.00 in cash, without interest and subject to any applicable withholding taxes.

Only those items amended or supplemented are reported in this Amendment No. 1. Except as specifically provided herein, the information contained in the Schedule TO remains unchanged and this Amendment No. 1 does not modify any of the information previously reported on the Schedule TO. You should read this Amendment No. 1 together with the Schedule TO, the Offer to Purchase, dated November 7, 2022, and the related Letter of Transmittal, as each may be amended or supplemented from time to time.

Item 4 is hereby amended and supplemented as follows:

The section of the Offer to Purchase captioned “7. Conditions of the Tender Offer” is amended as follows:

“Notwithstanding any other provision of the tender offer, we will not be required to accept for payment or pay for any shares tendered, and may terminate or amend the tender offer or may postpone the acceptance for payment of, and the payment for, shares tendered, subject to the requirements of the Exchange Act for prompt payment for or return of shares, if at any time on or after the date of this Offer to Purchase and before the Expiration Date any of the following events shall have occurred or are reasonably determined by us to have occurred, that, in the reasonable judgment of our Board of Directors and regardless of the circumstances giving rise to such event (other than any action or omission to act by us or our affiliates), makes it inadvisable to proceed with the tender offer or with acceptance for payment or payment:”

“Each of the conditions referred to above is for our sole benefit and may be asserted or waived by us, in whole or in part, prior to the Expiration Date. Any determination by us concerning the satisfaction of the conditions described above will be final and binding on all parties, except as finally determined in a subsequent judicial proceeding if our determinations are challenged by stockholders. Our failure at any time to exercise any of the foregoing rights will not be deemed a waiver of any right, and each such right will be deemed an ongoing right that may be asserted at any time prior to the Expiration Date; provided that, notwithstanding the foregoing, in the event that one or more of the events described above occurs, we will promptly notify security holders of our determination as to whether we will waive or modify the applicable condition(s) and continue the tender offer or terminate the tender offer. However, once the tender offer has expired, then all of the conditions to the tender offer must have been satisfied or waived. In certain circumstances, if we waive any of the conditions described above or otherwise elect to proceed with the tender offer despite any such conditions not being satisfied, then we may be required to extend the tender offer. Our right to terminate or amend the tender offer or to postpone the acceptance for payment of, or the purchase of and the payment for shares tendered if any of the above listed events occur (or shall have been reasonably determined by us to have occurred) at any time at or prior to the Expiration Date shall not be affected by any subsequent event, regardless of whether such subsequent event otherwise would have resulted in the event having been “cured” or ceasing to exist.”

Item 11 is hereby amended and supplemented as follows:

The section of the Offer to Purchase captioned “Cautionary Statement Concerning Forward-Looking Statements” is hereby amended as follows:

“The foregoing factors should not be construed as exhaustive. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made. New factors emerge from time to time and it is not possible for us to predict which will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.”
