IMPORTANT INFORMATION FOR SHAREHOLDERS AND INVESTORS This presentation shall not constitute an offer to sell, the solicitation of an offer to sell, or the solicitation of an offer to buy any securities or the solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. In connection with the proposed merger with FNB Financial Corp. (“FNB”), FB Financial Corporation (“FB Financial”) will file a registration statement on Form S-4 with the Securities and Exchange Commission (the “SEC”), which will contain the proxy statement of FNB and a prospectus of FB Financial. Investors and shareholders are encouraged to read the registration statement, including the proxy statement/prospectus that will be part of the registration statement, because it will contain important information about the proposed transaction, FNB, and FB Financial. After the registration statement is filed with the SEC, the proxy statement/prospectus and other relevant documents will be mailed to FNB shareholders and will be available for free on the SEC’s website (www.sec.gov).

Forward looking statements Certain statements contained in this presentation may constitute 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 timing, benefits, costs, and synergies of the proposed merger with FNB (which we refer to as the “FNB merger”), and FB Financial’s future plans, results, strategies, and expectations. These statements 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, many of which, by their nature, are inherently uncertain and beyond FB Financial’s control. The inclusion of these forward-looking statements should not be regarded as a representation by the FB Financial or any other person that such expectations, estimates, and projections will be achieved. Accordingly, FB Financial cautions shareholders and 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 FB Financial’s control. Although FB Financial believes that the expectations reflected in these forward- looking statements are reasonable as of the date of this 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 including, without limitation, (1) the risk that the cost savings and any revenue synergies from the proposed FNB merger or another acquisition may not be realized or take longer than anticipated to be realized, (2) disruption from the proposed FNB merger with customer, supplier, or employee relationships, (3) the occurrence of any event, change, or other circumstances that could give rise to the termination of the merger agreement with FNB, (4) the failure to obtain necessary regulatory approvals for the FNB merger, (5) the failure to obtain the approval of FNB’s shareholders for the merger, (6) the possibility that the costs, fees, expenses, and charges related to the FNB merger may be greater than anticipated, including as a result of unexpected or unknown factors, events, or liabilities, (7) the failure of the conditions to the FNB merger to be satisfied, (8) the risks related to the integration of acquired businesses (including the proposed FNB merger, FB Financial’s recent acquisition of branches from Atlantic Capital Bank, and any future acquisitions), including the risk that the integration of the acquired operations with those of FB Financial will be materially delayed or will be more costly or difficult than expected, (9) the risks associated with FB Financial’s pursuit of future acquisitions, (10) the risk of expansion into new geographic or product markets, (11) reputational risk and the reaction of the parties’ customers to the FNB merger, (12) FB Financial’s ability to successful execute its various business strategies, including its ability to execute on potential acquisition opportunities, (13) the risk of potential litigation or regulatory action related to the FNB merger, and (14) general competitive, economic, political, and market conditions. Many of these factors are beyond FB Financial’s ability to control or predict. If one or more events related to these or other risks or uncertainties materialize, or if FB Financial’s underlying assumptions prove to be incorrect, actual results may differ materially from the forward-looking statements. Accordingly, shareholders and investors should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date of this presentation, and FB Financial 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 FB Financial to predict their occurrence or how they will affect FB Financial. FB Financial qualifies all of its forward-looking statements by these cautionary statements. 2
Use of non-GAAP financial measures This 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. These non-GAAP financial measures include, without limitation, adjusted net income, adjusted diluted earnings per share, adjusted pro forma net income, adjusted pro forma diluted earnings per share, core noninterest expense, core noninterest income, core efficiency ratio (tax-equivalent basis), banking segment core efficiency ratio (tax-equivalent basis), mortgage segment core efficiency ratio (tax-efficiency basis), adjusted mortgage contribution, and adjusted return on average assets and equity. Each of these non-GAAP metrics excludes certain income and expense items that the Company’s management considers to be non-core/adjusted in nature. The Company refers to these non-GAAP measures as adjusted or core measures. The presentation also presents tangible assets, tangible common equity, tangible book value per common share, tangible common equity to tangible assets, return on tangible common equity, return on average tangible common equity, adjusted return on average assets, adjusted return on average equity, adjusted return on average tangible common equity, pro forma return on average assets and equity and pro forma adjusted return on average assets and equity. Each of these non-GAAP metrics excludes the impact of goodwill and other intangibles. 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 as management believes such measures facilitate period-to-period comparisons and provide meaningful indications of its operating performance as they eliminate both gains and charges that management views as non-recurring or not indicative of operating performance. 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 demonstrating the effects of significant non-core gains and charges in the current and prior periods. The Company’s management also believes that investors find these non-GAAP financial measures useful as they assist investors in understanding the Company’s underlying operating performance and in the analysis of ongoing operating trends. In addition, because intangible assets such as goodwill and other intangibles, and the other items excluded each vary extensively from company to company, the Company believes that the presentation of this information allows investors to more easily compare the Company’s results to the results of other companies. 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 the Company calculates 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 the Company has discussed herein when comparing such non- GAAP financial measures. The tables included in the Appendix to this presentation provide a reconciliation of these measures to the most directly comparable GAAP financial measures. 3
