Third Quarter 2018 Investor Presentation July 31, 2018

Certain statements contained in this investor presentation are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements include, without limitation, statements relating to the Company’s assets, business, cash flows, condition (financial or otherwise), credit quality, financial performance, liquidity, short and long-term performance goals, prospects, results of operations, the performance of the Company’s Banking and Mortgage Segments, strategic initiatives, the benefits, cost and synergies of the Clayton Banks acquisition, the timing, benefits, costs and synergies of future acquisitions, disposition and other growth opportunities and the performance of the banking and mortgage industry and the condition of the economy in general. These statements, which are based upon certain assumptions and estimates and describe the Company’s future plans, results, strategies and expectations, can generally be identified by the use of the words and phrases “may,” “will,” “should,” “could,” “would,” “goal,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target,” “aim,” “predict,” “continue,” “seek,” “projection” and other variations of such words and phrases and similar expressions. These forward-looking statements are not historical facts, and are based upon current expectations, estimates and projections about the Company’s industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond the Company’s control. The inclusion of these forward-looking statements should not be regarded as a representation by the Company or any other person that such expectations, estimates and projections will be achieved. Accordingly, the Company cautions investors that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict and that are beyond the Company’s control. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable as of the date of this investor presentation, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this investor presentation including, without limitation, the risks and other factors set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on March 16, 2018, filed with the SEC on May 10, 2018, under the captions “Cautionary note regarding forward-looking statements” and “Risk factors.” Many of these factors are beyond the Company’s ability to control or predict. If one or more events related to these or other risks or uncertainties materialize, or if the Company’s underlying assumptions prove to be incorrect, actual results may differ materially from the forward-looking statements. Accordingly, investors should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date of this investor presentation, and the Company does not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties may emerge from time to time, and it is not possible for the Company to predict their occurrence or how they will affect the Company.TerminologyIn this investor presentation, references to “we,” “our,” “us,” “FB Financial” or “the Company” refer to FB Financial Corporation, a Tennessee corporation, and our wholly owned bank subsidiary, FirstBank, a Tennessee state-chartered bank, unless otherwise indicated or the context otherwise requires. References to “Bank” or “FirstBank” refer to FirstBank, our wholly owned bank subsidiary.Contents of Investor PresentationExcept as is otherwise expressly stated, the contents of this investor presentation are presented as of the date on the front cover of this investor presentation. Market Data Market data used in this investor presentation has been obtained from government and independent industry sources and publications available to the public, sometimes with a subscription fee, as well as from research reports prepared for other purposes. Industry publications and surveys and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable. We did not commission the preparation of any of the sources or publications referred to in this presentation. We have not independently verified the data obtained from these sources, and, although we believe such data to be reliable as of the dates presented, it could prove to be inaccurate. Forward-looking information obtained from these sources is subject to the same qualifications and the additional uncertainties regarding the other forward-looking statements in this investor presentation. Forward looking statements 1

Use of non-GAAP financial measures This investor presentation contains certain financial measures that are not measures recognized under U.S. generally accepted accounting principles (GAAP) and therefore are considered non-GAAP financial measures. The Company’s management uses these non-GAAP financial measures in their analysis of the Company’s performance, financial condition and the efficiency of its operations. Management believes that these non-GAAP financial measures provide a greater understanding of ongoing operations and enhance comparability of results with prior periods as well as demonstrate the effects of significant gains and charges in the periods presented. The Company’s management also believes that investors find these non-GAAP financial measures useful as they assist investors in understanding our underlying operating performance and the analysis of ongoing operating trends. However, the non-GAAP financial measures discussed herein should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures discussed herein may differ from that of other companies reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar or with names similar to the non-GAAP financial measures we have discussed herein when comparing such non-GAAP financial measures. Below is a listing of the non-GAAP financial measures used in this investor presentation. Adjusted (pro forma) net income and earnings per share, the core efficiency ratio (tax equivalent basis), the Banking segment core efficiency ratio (tax-equivalent basis), the Mortgage segment core efficiency ratio (tax-equivalent basis), adjusted mortgage contribution, adjusted (pro forma) return on average assets, equity and tangible common equity and pro forma core total revenue are non-GAAP measures that exclude merger-related and conversion expenses, one time IPO equity grants, securities gains (losses), gain (loss) on sale of other real estate owned, and other selected items. The Company’s management uses these measures in their analysis of the Company’s performance. The Company’s management believes these measures provide a greater understanding of ongoing operations and enhance comparability of results with prior periods, as well as demonstrate the effects of significant gains and charges. Tangible book value per common share, tangible common equity to tangible assets, return on average tangible common equity and adjusted return on average tangible common equity are non-GAAP measures that exclude the impact of goodwill and other intangibles and are used by the Company’s management to evaluate capital adequacy. Because intangible assets such as goodwill and other intangibles vary extensively from company to company, we believe that the presentation of these non-GAAP financial measures allows investors to more easily compare the Company’s capital position to other companies. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures is provided in the Appendix to this investor presentation. 2
