Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of FB Financial Corporation (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive (loss) income, changes in shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report on Management’s Assessment of Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Allowance for Credit Losses on Loans – Reasonable and Supportable Forecasts and Qualitative Adjustments

As described in Note 1 – Basis of presentation and Note 3 – Loans and allowance for credit losses on loans HFI, the Company estimates expected credit losses for its financial assets carried at amortized cost utilizing the current expected credit loss (“CECL”) methodology. The allowance for credit losses (“ACL”) on loans held for investment on December 31, 2023 was$150.3 million. The provision for credit losses on loans held for investment for the year ended December 31, 2023 was$16.7 million.

The Company calculated an expected credit loss using a lifetime loss rate methodology. The Company utilizes probability-weighted forecasts that are developed by a third-party vendor, which consider multiple macroeconomic variables that are applicable to the type of loan. Each of the Company's loss rate models incorporate forward-looking macroeconomic projections throughout the reasonable and supportable forecast period and the subsequent historical reversion at the macroeconomic variable input level. The Company's loss rate models then estimate the lifetime loss rate for pools of loans by combining the calculated loss rate based on each variable within the model (including the macroeconomic variables). The lifetime loss rate for the pool is then multiplied by the loan balances to determine the expected credit losses on the pool. The Company then considers the need to qualitatively adjust its modeled quantitative expected credit loss estimate for information not already captured in the model loss estimation process.

The audit procedures over the determination of forecast scenarios involved a high degree of auditor judgment and required significant audit effort, including the use of more experienced audit personnel and our valuation specialists due to its complexity. Additionally, the audit procedures over the qualitative adjustments utilized in management’s methodology involved challenging and subjective auditor judgment. Therefore, we identified the following as a critical audit matter: a) auditing the forecasted macroeconomic scenario and b) auditing the identification and application of qualitative adjustments to the ACL model.

The primary audit procedures we performed to address this critical audit matter included the following:

•Tested the operating effectiveness of controls specific to:

◦Determining the reasonableness of the forecasted macroeconomic scenario used in the model,

◦The identification and application of qualitative adjustments to the ACL model,

◦The mathematical accuracy of the qualitative adjustments to the ACL model,

◦The relevance and reliability of data used by the Company’s third-party vendor to develop forecast scenarios.

◦The Company’s allowance committee’s oversight and review of the overall ACL.

•Evaluated management’s judgments in the selection and application of the forecasted macroeconomic scenarios.

•Used the work of specialists to assist in evaluating the relevance and reliability of data used by the Company’s third-party vendor to develop forecast scenarios.

•Evaluated management’s judgments in the identification and application of qualitative adjustments to the ACL model.

•Tested the completeness and accuracy of the data used in qualitative adjustments to the ACL model.
