CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Various statements contained in or incorporated by reference into this Quarterly Report on Form 10-Q (this “Quarterly Report”) are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The words “believe,” “anticipate,” “expect,” “may,” “will,” “assume,” “should,” “predict,” “could,” “would,” “intend,” “targets,” “estimates,” “projects,” “plans,” and “potential,” and other similar words and expressions of the future, are intended to identify such forward-looking statements, but other statements not based on historical information may also be considered forward-looking. All forward-looking statements are subject to risks, uncertainties, and other factors that may cause the actual results, performance, or achievements of Reliant Bancorp, Inc. (“Reliant Bancorp”) to differ materially from any results, performance, or achievements expressed or implied by such forward-looking statements. Such risks, uncertainties, and other factors include, among others:

(1) the global health and economic crisis precipitated by the coronavirus (COVID-19) pandemic;

(2) actions taken by governments, businesses and individuals in response to the coronavirus (COVID-19) pandemic;

(3) the pace of recovery when the coronavirus (COVID-19) pandemic subsides;

(4) the possible recurrence of the coronavirus (COVID-19);

(5) changes in political conditions or the legislative or regulatory environment, including governmental initiatives affecting the financial services industry such as, but not limited to, the Coronavirus Aid, Relief, and Economic Security Act (or the CARES Act);

(6) the possibility that our asset quality could decline or that we experience greater loan losses than anticipated;

(7) increased levels of other real estate, primarily as a result of foreclosures;

(8) the impact of liquidity needs on our results of operations and financial condition;

(9) competition from financial institutions and other financial service providers;

(10) the effect of interest rate increases on the cost of deposits;

(11) unanticipated weakness in loan demand or loan pricing;

(12) greater than anticipated adverse conditions in the national economy or local economies in which we operate, including Middle Tennessee;

(13) lack of strategic growth opportunities or our failure to execute on available opportunities;

(14) deterioration in the financial condition of borrowers resulting in significant increases in loan losses and provisions for those losses;

(15) economic crises and associated credit issues in industries most impacted by the coronavirus (COVID-19) pandemic, including the restaurant, hospitality and retail sectors;

(16) the ability to grow and retain low-cost core deposits and retain large, uninsured deposits;

(17) our ability to effectively manage problem credits;

(18) our ability to successfully implement efficiency initiatives on time and with the results projected;

(19) our ability to successfully develop and market new products and technology;

(20) the impact of negative developments in the financial industry and United States and global capital and credit markets;

(21) our ability to retain the services of key personnel;

(22) our ability to adapt to technological changes;

(23) risks associated with litigation, including the applicability of insurance coverage;

(24) the vulnerability of the computer and information technology systems and networks of Reliant Bank (the “Bank”), and the systems and networks of third parties with whom Reliant Bancorp or the Bank contract, to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss, and other security breaches and interruptions;

(25) changes in state and federal laws, rules, regulations, or policies applicable to banks or bank or financial holding companies, including regulatory or legislative developments;

(26) adverse results (including costs, fines, reputational harm, and/or other negative effects) from current or future litigation, regulatory examinations, or other legal or regulatory actions;

(27) the risk that expected cost savings and revenue synergies from (a) the merger of Reliant Bancorp and Tennessee Community Bank Holdings, Inc. (“TCB Holdings”) (the “TCB Holdings Transaction”) or (b) the merger of Reliant Bancorp and First Advantage Bancorp (“FABK”) (the “FABK Transaction” and, together with the TCB Holdings Transaction, collectively, the “Transactions”), may not be realized or may take longer than anticipated to be realized;

(28) the effect of the Transactions on our customer, supplier, or employee relationships and operating results (including without limitation difficulties in maintaining relationships with employees and customers), as well as on the market price of Reliant Bancorp’s common stock;

(29) the risk that the businesses and operations of TCB Holdings and its subsidiaries and of FABK and its subsidiaries cannot be successfully integrated with the business and operations of Reliant Bancorp and its subsidiaries or that integration will be more costly or difficult than expected;

2

---

(30) the amount of costs, fees, expenses, and charges related to the Transactions, including those arising as a result of unexpected factors or events;

(31) reputational risk associated with and the reaction of our customers, suppliers, employees, or other business partners to the Transactions;

(32) the risk associated with Reliant Bancorp management’s attention being diverted away from the day-to-day business and operations of Reliant Bancorp to the integration of the Transactions; and

(33) general competitive, economic, political, and market conditions, including economic conditions in the local markets where we operate.

Further, statements about the potential effects of the coronavirus (COVID-19) pandemic on our business, financial condition, liquidity, or results of operations may constitute forward-looking statements and are subject to the risk that the actual effects may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable, and in many cases beyond our control, including the scope and duration of the pandemic, actions taken by governmental authorities in response to the pandemic, and the direct and indirect impact of the pandemic on our customers, other third parties, and us.

You should also consider carefully the risk factors discussed in Part I, Item 1A. "Risk Factors" of our most recent Annual Report on Form 10-K and in Part II, Item 1A. "Risk Factors" in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, which address additional factors that could cause our actual results to differ from those set forth in forward-looking statements and could materially and adversely affect our business, operating results, and financial condition. The risks discussed in this Quarterly Report are factors that, individually or in the aggregate, management believes could cause our actual results to differ materially from expected and historical results. You should understand that it is not possible to predict or identify all such factors, many of which are beyond our ability to control or predict. Consequently, you should not consider such disclosures to be a complete discussion of all potential risks or uncertainties. Factors not here or otherwise listed may develop or, if currently extant, we may not have yet recognized them.

Forward-looking statements speak only as of the date on which they are made, and, except to the extent required by federal securities laws, we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. 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.

(Dollar amounts in thousands except per share amounts)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of Reliant Bancorp, Inc. conform to accounting principles generally accepted in the United States of America ("U.S. GAAP") and to general practices within the banking industry. The following is a brief summary of the significant policies.

Nature of Operations

Reliant Bancorp, Inc. is a Tennessee corporation and the holding company for and the sole shareholder of Reliant Bank. Reliant Bancorp is registered as a financial holding company under the Bank Holding Company Act of 1956, as amended ("Bank Holding Company Act"). Reliant Bank is a commercial bank chartered under Tennessee law and a member of the Federal Reserve System (the "Federal Reserve"). Reliant Bank, Reliant Bancorp's wholly-owned bank subsidiary, provides a full range of traditional banking products and services to business and consumer clients throughout Middle Tennessee and the Nashville-Davidson-Murfreesboro-Franklin, TN Metropolitan Statistical Area (the “Nashville MSA”) and Chattanooga, Tennessee. Reliant Bank operates banking centers in Cheatham, Davidson, Hamilton, Hickman, Maury, Montgomery, Robertson, Rutherford, Sumner, and Williamson counties, Tennessee. Additionally, Reliant Bank operates mortgage offices in Brentwood, Chattanooga, Hendersonville, and Memphis, Tennessee, as well as two in Little Rock and one in Crossett, Arkansas. On January 1, 2020, TCB Holdings, a community banking organization headquartered in Ashland City, Tennessee, was merged with and into Reliant Bancorp. On April 1, 2020, First Advantage Bancorp, a community banking organization headquartered in Clarksville, Tennessee, was merged with and into Reliant Bancorp (See Note 12).

Reliant Risk Management, Inc., a newly-formed, wholly-owned insurance captive subsidiary of Reliant Bancorp, Inc. that began operations on June 1, 2020, is a Tennessee-based captive insurance company which insures Reliant Bancorp and the Bank against certain risks unique to their operations and for which insurance may not be currently available or economically feasible in today's insurance marketplace. Reliant Risk Management, Inc. pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. Reliant Risk Management, Inc. is subject to regulations of the State of Tennessee and undergoes periodic examinations by the Tennessee Department of Commerce and Insurance.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Quarterly Report on Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with U.S. GAAP.  All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods covered by the report have been included.  The accompanying unaudited consolidated financial statements should be read in conjunction with Reliant Bancorp, Inc.’s consolidated financial statements and related notes appearing in Reliant Bancorp, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2019.

The consolidated financial statements as of and for the periods presented include the accounts of Reliant Bancorp, Inc., Reliant Bank (the "Bank"), Community First Trups Holding Company ("TRUPS"), which is wholly owned by Reliant Bancorp, Inc., Reliant Risk Management, Inc. ("Risk"), which is wholly owned by Reliant Bancorp Inc., Reliant Investment Holdings, LLC ("Holdings"), which is wholly owned by the Bank, and Reliant Mortgage Ventures, LLC ("RMV"), of which the Bank controls 51% of the governance rights. Reliant Bancorp Inc., the Bank, TRUPS, Risk, Holdings, and RMV are collectively referred to herein as the “Company”. All significant inter-company balances and transactions have been eliminated in consolidation. As described in Note 12 to these unaudited consolidated financial statements, Reliant Bancorp, Inc. and TCB Holdings merged effective on January 1, 2020, and Reliant Bancorp, Inc. and FABK merged effective April 1, 2020. The accounting and reporting policies of the Company conform to U.S. GAAP and general practices in the banking industry.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material

JUNE 30, 2020 AND 2019 (UNAUDITED) AND DECEMBER 31, 2019

(Dollar amounts in thousands except per share amounts)

estimates that are particularly susceptible to significant change in the near term relate to determination of the allowance for loan losses, the valuation of other real estate, the valuation of debt and equity securities, the valuation of deferred tax assets and fair values of financial instruments.

The consolidated financial statements as of June 30, 2020, and for the three and six months ended June 30, 2020 and 2019, included herein have not been audited. The accounting and reporting policies of the Company conform to U.S. GAAP and Article 8 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although the Company believes that the disclosures made are adequate to make the information not misleading.

The accompanying consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary to present a fair statement of the results for the interim periods presented. Such adjustments are of a normal recurring nature. The Company evaluates subsequent events through the date of filing. Certain prior period amounts have been reclassified to conform to the current period presentation. The results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020.

Recently Adopted Accounting Pronouncements

Information about certain issued accounting standards updates is presented below. Also refer to Note 1 - Summary of Significant Accounting Policies, “Recent Authoritative Accounting Guidance” in the Annual Report on Form 10-K for the year ended December 31, 2019 for additional information related to previously issued accounting standards updates.

ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 went into effect for the Company on January 1, 2020 and the Company elected the prospective application approach provided by ASU 2018-11 and did not adjust prior periods for ASC 842. The Company also elected certain practical expedients within the standard and consistent with such elections did not reassess whether any expired or existing contracts are or contain leases, did not reassess the lease classification for any expired or existing leases, and did not reassess any initial direct costs for existing leases. The effect of implementing this pronouncement resulted in right to use assets of $11,973 and a similar corresponding liability, as of January 1, 2020.

ASU 2020-04, "Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting." In March 2020, the FASB issued Topic 848 amendments to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. It provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company has evaluated the effect of the pronouncement on the consolidated financial statements, noting no significant impact.

Newly Issued not yet Effective Accounting Standards

ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available for sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 is expected to be effective on January 1, 2023. We are currently evaluating the potential impact of ASU 2016-13 on the Company's financial statements. We are currently developing an implementation plan to include assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs, among other things. The adoption of ASU 2016-13 could result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses

(Dollar amounts in thousands except per share amounts)

allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, ASU 2016-13 will necessitate that we establish an allowance for expected credit losses for certain debt securities and other financial assets. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Financial Instruments - Credit Losses (ASC 326), Derivatives and Hedging (ASC 815), and Financial Instruments (ASC 825). The amendments in this ASU improve the codification by eliminating inconsistencies and providing clarifications. The amended guidance in this ASU related to credit losses will be effective for the Company for fiscal years and interim periods beginning after December 15, 2022. The Company is currently evaluating the impact of these ASUs on the Company’s consolidated financial statements. While we are currently unable to reasonably estimate the impact of adopting these ASUs, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of the Company's loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date.

ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for the Company on January 1, 2021, with earlier adoption permitted and is not currently expected to have a significant impact on the Company's consolidated financial statements as it simplifies the test of impairment of goodwill.

Due in one to five years			2,179						2,180
Due in five to ten years			14,693						15,379

Total temporarily impaired			$	18,064					$	322					$	29,262					$	913					$	47,326					$	1,235

Management has the intent and ability to hold all securities in an unrealized loss position for the foreseeable future, and the decline in fair value is largely due to changes in interest rates. The fair value is expected to recover as the securities approach their maturity date and/or market rates decline. There were 37 and 47 securities in an unrealized loss position as of June 30, 2020 and December 31, 2019, respectively.

JUNE 30, 2020 AND 2019 (UNAUDITED) AND DECEMBER 31, 2019

(Dollar amounts in thousands except per share amounts)

Risk characteristics relevant to each portfolio segment are as follows:

Commercial, industrial and agricultural: The commercial, industrial and agricultural loan portfolio segment includes loans to commercial customers for use in normal business operations to finance working capital needs, equipment purchases or other expansion projects. Collection risk in this portfolio is driven by the creditworthiness of underlying borrowers, particularly cash flow from customers’ business operations. Commercial, industrial and agricultural loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial and industrial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis.

Multi-family and commercial real estate: Multi-family and commercial real estate loans are subject to underwriting standards and processes similar to commercial, industrial and agricultural loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate.

Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties comprising the Company’s commercial real estate portfolio are diverse in terms of type. This diversity helps reduce the Company’s exposure to adverse economic events that affect any single market or industry. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. The Company also utilizes third-party experts to provide insight and guidance about economic conditions and trends affecting the market areas it serves. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans. Non-owner occupied commercial real estate loans are loans secured by multifamily and commercial properties where the primary source of repayment is derived from rental income associated with the property (that is, loans for which 50 percent or more of the source of repayment comes from third party, nonaffiliated, rental income) or the proceeds of the sale, refinancing, or permanent financing of the property.

These loans are made to finance income-producing properties such as apartment buildings, office and industrial buildings, and retail properties. Owner-occupied commercial real estate loans are loans where the primary source of repayment is the cash flow from the ongoing operations and business activities conducted by the party, or an affiliate of the party, who owns the property.

Construction and land development: Loans for non-owner-occupied real estate construction or land development are generally repaid through cash flow related to the operation, sale or refinance of the property. The Company also finances construction loans for owner-occupied properties. A portion of the Company’s construction and land development portfolio segment is comprised of loans secured by residential product types (residential land and single-family construction). With respect to construction loans to developers and builders that are secured by non-owner occupied properties that the Company may originate from time to time, the Company generally requires the borrower to have had an existing relationship with the Company and have a proven record of success. Construction and land development loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates, market sales activity, and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing.

1-4 family residential real estate: Residential real estate loans, which include related manufactured homes with real estate, represent loans to consumers or investors to finance a residence. These loans are typically financed on 15- to 30-year amortization terms, but generally with shorter maturities of 5 to 15 years. Many of these loans are extended to borrowers to finance their primary or secondary residence. Loans to an investor secured by a 1-4 family residence will be repaid from either the rental income from the property or from the sale of the property. This loan segment also includes closed-end home equity loans that are secured by a first or second mortgage on the borrower’s residence. This allows customers to borrow against the equity in their home. Loans in this portfolio segment are underwritten and approved based on a number of credit quality criteria including limits on maximum Loan-to-Value ("LTV"), minimum credit scores, and maximum debt to income. Real estate market values as of the time the loan is made directly affect the amount of credit extended and, in addition, changes in these market values impact the depth of potential losses in this portfolio segment.

1-4 family HELOC: This loan segment includes open-end home equity loans that are secured by a first or second mortgage on the borrower’s residence. This allows customers to borrow against the equity in their home utilizing a revolving line of credit. These loans are underwritten and approved based on a number of credit quality criteria including limits on maximum LTV, minimum credit scores, and maximum debt to income. Real estate market values as of the time the loan is made directly affect the amount of credit extended and, in addition, changes in these market values impact the depth of potential losses in this portfolio segment. Because of the revolving nature of these loans as well as the fact that many represent second mortgages, this portfolio segment can contain more risk than the amortizing 1-4 family residential real estate loans.

Consumer: The consumer loan portfolio segment includes non-real estate secured direct loans to consumers for household, family, and other personal expenditures as well as manufactured homes without real estate. Consumer loans may be secured or unsecured and are usually structured with short or medium term maturities. These loans are underwritten and approved based on a number of consumer credit quality criteria including limits on maximum LTV on secured consumer loans, minimum credit scores, and maximum debt to income. Many traditional forms of consumer installment credit have standard monthly payments and fixed repayment schedules of one to five years. These loans are made with either fixed or variable interest rates that are based on specific indices. Loans to finance manufactured homes that are not secured by real estate are classified as consumer loans and have standard monthly payments and fixed repayment schedules of 15 to 23 years. Installment loans fill a variety of needs, such as financing the purchase of an automobile, a boat, a recreational vehicle, or other large personal items, or for consolidating debt. These loans may be unsecured or secured by an assignment of title, as in an automobile loan, or by money in a bank account. In addition to consumer installment loans, this portfolio segment also includes secured and unsecured personal lines of credit as well as overdraft protection lines. Loans in this portfolio segment are sensitive to unemployment and other key consumer economic measures.

The Company utilizes a risk grading system to monitor the credit quality of the Company’s commercial loan portfolio which consists of commercial, industrial and agricultural, commercial real estate and construction loans. Loans are graded on a scale of 1 to 9. Grades 1 to 5 are pass credits, grade 6 is special mention, grade 7 is substandard, grade 8 is doubtful and grade 9 is loss. A description of the risk grades are as follows:

        Grade 1 - Minimal Risk (Pass)

This grade includes loans to borrowers with a strong financial position and history of profits and cash flows sufficient to service the debt. These borrowers have well defined sources of primary/secondary repayment, conservatively leveraged balance sheets and the ability to access a wide range of financing alternatives. Collateral securing these loans is negotiable, of sufficient value and in possession of the Company. Risk of loss is unlikely.

        Grade 2 - High Quality (Pass)

This grade includes loans to borrowers with a strong financial condition reflecting dependable net profits and cash flows. The borrower has verifiable liquid net worth providing above average asset protection. An identifiable market exists for the collateral. Risk of loss is unlikely.

        Grade 3 - Above Average (Pass)

This grade includes loans to borrowers with a balance sheet that reflects a comfortable degree of leverage and liquidity. Borrowers are profitable and have a sustained record of servicing debt. An identifiable market exists for the collateral, but liquidation could take up to one year. Risk of loss is unlikely.

        Grade 4 - Average (Pass)

This grade includes loans to borrowers with a financial condition that is satisfactory and comparable to industry standards. The borrower has verifiable net worth, providing over time average asset protection. The borrower's cash flows are sufficient to satisfy debt service requirements. Risk of loss is below average.

        Grade 5 - Acceptable (Management Attention) (Pass)

This grade includes loans to borrowers whose loans are performing, but sources of repayment are not documented by the current credit analysis. There are some declining trends in margins, ratios and/or cash flow. Guarantor(s) have strong net worth(s), but assets may be concentrated in real estate or other illiquid investments. Risk of loss is average.

        Grade 6 - Special Mention

Special mention assets have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company’s position at some future date. These assets pose elevated risk, but their weakness does not yet justify a substandard classification. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or an ill proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a special mention rating. Nonfinancial reasons for rating a credit exposure special mention include management problems, pending litigation, an ineffective loan agreement or other material structural weakness, and any other significant deviation from prudent lending practices. The special mention rating is designed to identify a specific level of risk and concern about asset quality. Although a special mention asset has a higher probability of default than a pass asset, its default is not imminent.

        Grade 7 - Substandard

A ‘‘substandard’’ extension of credit is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Extensions of credit so classified should have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard credits, does not have to exist in individual extensions of credit classified substandard. Substandard assets have a high probability of payment default, or they have other well-defined weaknesses. They require more intensive supervision by Company management. Substandard assets are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk mitigation.

JUNE 30, 2020 AND 2019 (UNAUDITED) AND DECEMBER 31, 2019

(Dollar amounts in thousands except per share amounts)

Grade 8 - Doubtful

An extension of credit classified ‘‘doubtful’’ has all the weaknesses inherent in one classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors that may work to the advantage of and strengthen the credit, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors may include a proposed merger or acquisition, liquidation proceedings, capital injection, perfecting liens on additional collateral, or refinancing plans. Generally, the doubtful classification should not extend for a long period of time because in most cases the pending factors or events that warranted the doubtful classification should be resolved either positively or negatively in a reasonable period of time.

        Grade 9 - Loss

Extensions of credit classified ‘‘loss’’ are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the credit has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. Amounts classified loss should be promptly charged off. The Company will not attempt long term recoveries while the credit remains on the Company’s books. Losses should be taken in the period in which they surface as uncollectible. With loss assets, the underlying borrowers are often in bankruptcy, have formally suspended debt repayments, or have otherwise ceased normal business operations. Once an asset is classified loss, there is little prospect of collecting either its principal or interest.

Non-commercial purpose loans are initially assigned a default loan grade of 99 (Pass) and are risk graded (Grade 6, 7, or 8) according to delinquency status when applicable.

loans with principal balances of $530.7 million. The majority of these modifications were for a period of up to three months and contained either interest-only periods or full payment deferrals. Through August 5, 2020, further modifications were approved for $39.0 million of the loans previously modified. Additional modifications of these loans are likely to be executed in the third quarter of 2020.

The CARES Act provides over $2.0 trillion in emergency economic relief to individuals and businesses impacted by the COVID-19 pandemic. The CARES Act authorized the Small Business Administration (“SBA”) to administer new loan programs including, but not limited to, the guarantee of loans under a new 7(a) loan program called the Paycheck Protection Program (“PPP”). Upon completion of the FABK Transaction as disclosed in Note 12, we assumed their qualified SBA lender status. The Company originated $83.3 million of PPP loans in the second quarter of 2020 which are included in the commercial, industrial, and agricultural segment.

The Company has acquired loans for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected.

NOTE 4 - OTHER REAL ESTATE

At June 30, 2020, and December 31, 2019, the Company held other real estate recorded at a value of $2,514 and $750, respectively, which represents fair value less costs to sell. The June 30, 2020 balance included retired bank facilities of $2,420 and two manufactured housing properties valued at $94. These residential properties were part of the four properties valued at $208 added through the acquisition of First Advantage Bank in the second quarter of 2020. During the three months ended June 30, 2020, the Company sold two of these properties resulting in a gain on sale of $11. Additionally, at June 30, 2020, there were three real estate loans with related balances totaling $320 in the process of foreclosure. Of the two retired bank facilities no longer in use, one sold as of July 31, 2020. Expenses related to other real estate totaled $4 for the three and six months ended June 30, 2020, respectively.

NOTE 5 - FAIR VALUES OF ASSETS AND LIABILITIES

 

Financial accounting standards relating to fair value measurements establish a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1 Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

Level 2 Inputs to the valuation methodology include:

•Quoted prices for similar assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in inactive markets;

•Inputs other than quoted prices that are observable for the asset or liability; and

•Inputs that are derived principally from or corroborated by the observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 Inputs to the valuation methodology are unobservable and reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques should maximize the use of observable inputs and minimize the use of unobservable inputs.

Following is a description of the valuation methodologies used for assets and liabilities measured at fair value on a recurring basis:

Securities available for sale: The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The Company obtains fair value measurements for securities available for sale from an independent pricing service. The fair value measurements consider observable data that may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, cash flows and reference data, including market research publications, among other things.

        Interest rate swaps: The fair values of interest rate swaps are determined based on discounted future cash flows.

Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Assets and liabilities measured at fair value on a nonrecurring basis include the following:

Impaired Loans: The fair value of an impaired loan with specific allocations of the allowance for loan losses is generally based on the present value of expected payments using the loan’s effective rate as the discount rate or recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value.

JUNE 30, 2020 AND 2019 (UNAUDITED) AND DECEMBER 31, 2019

(Dollar amounts in thousands except per share amounts)

Other Real Estate: The fair value of other real estate is generally based on recent real estate appraisals less estimated disposition cost. These appraisals may use a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in Level 3 classification of the inputs for determining fair value.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company’s valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.

The following table sets forth the Company’s major categories of assets and liabilities measured at fair value on a recurring basis, by level within the fair value hierarchy, as of June 30, 2020 and December 31, 2019:

The methods and assumptions used to estimate fair value are described as follows:

Carrying amount is the estimated fair value for cash and cash equivalents, accrued interest receivable and payable,  restricted equity securities, federal funds sold or purchased, demand deposits, and variable rate loans or deposits that re-price frequently and fully. For fixed rate loans or deposits and for variable rate loans or deposits with infrequent re-pricing or re-pricing limits, fair value is based on discounted cash flows using current market rates applied to the estimated life and credit risk. Fair value of debt is based on discounted cash flows using current rates for similar financing.

NOTE 6 - STOCK-BASED COMPENSATION

In 2006, the Board of Directors and shareholders of the Bank (then known as "Commerce Union Bank") approved the Commerce Union Bank Stock Option Plan (the “Plan”). The Plan provided for the granting of stock options for up to 625,000 shares of Bank common stock to employees and organizers and authorized the issuance of Bank common stock upon the exercise of such options. As part of the Bank's reorganization into a holding company corporate structure in 2012, all Bank options were replaced with Commerce Union Bancshares, Inc. (now known as "Reliant Bancorp, Inc.") options with no change in terms.

On March 10, 2015, the shareholders of Reliant Bancorp (then known as "Commerce Union Bancshares, Inc.") approved the Commerce Union Bancshares, Inc. Amended and Restated Stock Option Plan (the “A&R Plan”), which permits the grant of awards with respect to up to 1,250,000 shares of Reliant Bancorp common stock in the form of stock options. As part of the merger of Commerce Union Bank and Reliant Bank in 2015, all outstanding stock options of Reliant Bank were converted to stock options of Reliant Bancorp (then known as "Commerce Union Bancshares, Inc.") under the A&R Plan. Under the A&R Plan, stock option awards may be granted in the form of incentive stock options or non-statutory stock options, and are generally exercisable for up to 10 years following the date such option awards are granted. Exercise prices of incentive stock options must be equal to or greater than the fair market value of Reliant Bancorp's common stock on the grant date.

        

On June 18, 2015, the shareholders of Reliant Bancorp (then known as "Commerce Union Bancshares, Inc.") approved the Commerce Union Bancshares, Inc. 2015 Equity Incentive Plan, which reserves up to 900,000 shares of Reliant Bancorp common stock to be subject to awards under the plan, including awards in the form of stock options, restricted stock grants, performance-based awards, and other awards denominated or payable by reference to or based on or related to Reliant Bancorp common stock.

NOTE 7 - REGULATORY CAPITAL REQUIREMENTS

The Bank is subject to regulatory capital requirements administered by the federal and state banking agencies. As of June 30, 2020, Reliant Bancorp fell under the Federal Reserve's Small Bank Holding Company and Savings and Loan Holding Company Policy Statement (the “Small Bank Holding Company Policy Statement”), which is generally applicable to bank holding companies with consolidated assets of less than $3 billion, and was, therefore, not subject to consolidated capital requirements. However, we have chosen to provide our consolidated capital ratios below. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believes as of June 30, 2020, the Bank meets all capital adequacy requirements to which it is subject.

Prompt corrective action regulations provide five bank capital classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If only adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At June 30, 2020 and December 31, 2019, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category.

In July 2013, the Federal Deposit Insurance Corporation (FDIC) approved final rules that substantially amended the regulatory risk-based capital rules applicable to Reliant Bancorp and the Bank. The final rules implement the regulatory capital reforms of the Basel Committee on Banking Supervision reflected in “Basel III: A Global Framework for More Resilient Banks and Banking Systems” ("Basel III") and changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act.

JUNE 30, 2020 AND 2019 (UNAUDITED) AND DECEMBER 31, 2019

(Dollar amounts in thousands except per share amounts)

Under these rules, the leverage and risk-based capital ratios of bank holding companies (other than bank holding companies that

fall under the Small Bank Holding Company Policy Statement and are not subject to consolidated capital requirements) may not be lower than the leverage and risk-based capital ratios for insured depository institutions. The final rules implementing Basel III became effective on January 1, 2015, and include new minimum risk-based capital and leverage ratios and a new common equity tier 1 ratio. In addition, these rules refine the definition of what constitutes capital for purposes of calculating those ratios, including the definitions of Tier 1 capital and Tier 2 capital.

Basel III established a “capital conservation buffer” of 2.5%. An institution is subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if capital levels fall below minimum levels plus the buffer.

Capital amounts and ratios for Reliant Bancorp and the Bank (required) are presented below as of June 30, 2020 and December 31, 2019.

NOTE 9 - SEGMENT REPORTING

The Company has two reportable business segments: retail banking and residential mortgage banking. Segment information is derived from the internal reporting system utilized by management. Revenues and expenses for segments reflect those which can be specifically identified and have been assigned based on internally developed allocation methods. Financial results have been presented, to the extent practicable, as if each segment operated on a stand-alone basis.

Retail Banking provides deposit and lending services to consumer and business customers within our primary geographic markets. Our customers are serviced through branch locations, ATMs, online banking, and mobile banking.

Residential Mortgage Banking originates traditional first lien residential mortgage loans and first lien home equity lines of credit throughout the United States. The traditional first lien residential mortgage loans are typically underwritten to government agency standards and sold to third-party secondary market mortgage investors. The home equity lines of credit are typically sold to participating banks or other investor groups and are underwritten to their standards.

During the second quarter of 2019, RMV began acquiring loans from approved correspondent lenders and reselling them in the secondary market. These loans are not government agency-qualified loans and are of higher risk, such as jumbo loans or senior position home equity lines of credit.

NOTE 10 - DERIVATIVES

The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and other terms of the individual interest rate swap agreements.

Interest Rate Swaps Designated as Cash Flow Hedges

Interest rate swaps with notional amounts totaling $160,000 as of June 30, 2020 were designated as cash flow hedges of certain short-term interest-bearing liabilities and subordinated debentures, which are fully effective. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swaps is recorded in other assets (liabilities) with changes in fair value recorded in other comprehensive income (loss). The amount included in accumulated other comprehensive income (loss) would be reclassified to current earnings should the hedges no longer be considered effective. The Company expects the hedges to remain fully effective during the remaining terms of the swap agreements.

Summary information related to the interest rate swaps designated as cash flow hedges as of June 30, 2020, is as follows:

Notional amounts			$	160,000
Weighted average pay rates			2.050		%
Weighted average receive rates			1.679		%
Weighted average maturity			3.60 years
Unrealized losses			$	9,034

NOTE 11 – INCOME TAXES

Income tax expense for the three and six months ended June 30, 2020 totaled $1,634 and $724, respectively, compared to $501 and $873, respectively, for the three and six months ended June 30, 2019. The effective tax rate for the three and six months ended June 30, 2020 was 17.9% and 10.3%, respectively, compared to 15.7% and 15.0%, respectively, for the three and six months ended June 30, 2019. During the three and six months ended June 30, 2020, merger expenses and the provision expense had the impact of reducing taxable income and increasing the proportion of tax-exempt income to total income.

Effective January 1, 2020, Reliant Bancorp completed the acquisition of TCB Holdings pursuant to the Agreement and Plan of Merger, dated September 16, 2019 (the “TCB Holdings Agreement”), by and among Reliant Bancorp, TCB Holdings, and Community Bank & Trust, a Tennessee-chartered commercial bank and wholly owned subsidiary of TCB Holdings (“CBT”). On the terms and subject to the conditions set forth in the TCB Holdings Agreement, TCB Holdings merged with and into the Reliant Bancorp (the “TCB Holdings Transaction”), with Reliant Bancorp as the surviving corporation. Immediately following the TCB Holdings Transaction, CBT merged with and into the Bank, with the Bank continuing as the surviving banking corporation. Pursuant to the TCB Holdings Agreement, at the effective time of the TCB Holdings Transaction, each outstanding share of TCB Holdings common stock, par value $1.00 per share (other than certain excluded shares), was converted into and canceled in exchange for the right to receive (i) $17.13 in cash, without interest, and (ii) 0.769 shares of the Reliant Bancorp’s common stock, par value $1.00 per share (“Reliant Bancorp Common Stock”). The aggregate consideration payable by Reliant Bancorp in respect of shares of TCB Holdings common stock as consideration for the TCB Holdings Transaction was 811,210 shares of Reliant Bancorp Common Stock and approximately $18,073 in cash. Reliant Bancorp did not issue fractional shares of Reliant Bancorp Common Stock in connection with the TCB Holdings Transaction, but paid cash in lieu of fractional shares based on the volume weighted average closing price per share of the Reliant Bancorp Common Stock on The Nasdaq Capital Market for the 10 consecutive trading days ending on and including December 30, 2019 (calculated as $22.36). At the effective time of the TCB Holdings Transaction, each outstanding option to purchase TCB Holdings common stock was canceled in exchange for a cash payment in an amount equal to the product of (i) $34.25 minus the per share exercise price of the option multiplied by (ii) the number of shares of TCB Holdings common stock subject to the option (to the extent not previously exercised). Reliant Bancorp paid aggregate consideration to holders of unexercised options of approximately $430. All shares of Reliant Bancorp’s common stock outstanding immediately prior to the TCB Holdings Transaction were unaffected by the TCB Holdings Transaction.

The following table details the financial impact of the TCB Holdings Transaction, including the calculation of the purchase price, the allocation of the purchase price to the fair values of net assets assumed and goodwill recognized:

Pursuant to the FABK Agreement, at the effective time of the FABK Transaction, each outstanding share of FABK common stock, par value $0.01 per share (the “FABK Common Stock”), other than certain excluded shares, was converted into the right to receive (i) 1.17 shares of Reliant Bancorp Common Stock and (ii) $3.00 in cash, without interest. In lieu of the issuance of fractional shares of Reliant Bancorp Common Stock, Reliant Bancorp agreed to pay cash in lieu of fractional shares based on the volume-weighted average closing price per share of Reliant Bancorp Common Stock on The Nasdaq Capital Market for the 10 consecutive trading days ending on and including March 30, 2020 (calculated as $11.74). Based on the April 1, 2020 opening price for Reliant Bancorp Common Stock of $11.27 per share and 3,935,165 shares of FABK Common Stock outstanding on April 1, 2020, the consideration for the FABK Transaction was approximately $64,094, in the aggregate, or $16.28 per share of FABK Common Stock.

Supplemental Pro Forma Combined Condensed Statements of Income

Pro forma data for the three and six months ended June 30, 2020 and 2019 in the table below presents information as if the TCB Holdings Transaction and FABK Transaction occurred on January 1, 2019. These results combine the historical results of TCB Holdings and FABK into the Company's consolidated statement of income and, while certain adjustments were made for the estimated impact of certain fair value adjustments, they are not indicative of what would have occurred had the acquisitions taken place on the indicated date nor are they intended to represent or be indicative of future results of operations. In particular, no adjustments have been made to eliminate the amount of TCB Holdings' or FABK's provision for credit losses for the first three and six months of 2019 that may not have been necessary had the acquired loans been recorded at fair value as of the beginning of 2019. Additionally, these financials were not adjusted for non-recurring expenses, such as merger-related charges incurred by either the Company, TCB Holdings or FABK. The Company expects to achieve operating cost savings and other business synergies as a result of the acquisitions which are also not reflected in the pro forma amounts.

NOTE 13 - LEASES

On January 1, 2020, the Company adopted ASU No. 2016-02 “Leases (Topic 842)” and all subsequent ASUs that modified Topic 842. The Company elected the prospective application approach provided by ASU 2018-11 and did not adjust prior periods for ASC 842. Leases with initial terms of less than one year are not recorded on the balance sheet.

The Company’s long-term lease agreements are classified as operating leases. Certain of these leases offer the option to extend the lease term and the Company has included such extensions in its calculation of the lease liabilities to the extent the options are reasonably assured of being exercised. The lease agreements do not provide for residual value guarantees and have no restrictions or covenants that would impact dividends or require incurring additional financial obligations.

The implementation of the new standard resulted in recognition of a right-of-use asset of $12.0 million and a lease liability of $11.9 million at the date of adoption, which is related to the Company’s lease of premises used in operations. The Company used a discount rate of 4.5% in determining the right-of-use asset and lease liability as of January 1, 2020.

Information related to the Company's operating leases is presented below:

			June 30, 2020
Operating leases right of use assets			$	15,452
Operating lease liabilities			$	16,591
Weighted average remaining lease term (in years)			6.62

Formation of Reliant Risk Management, Inc.

Reliant Risk Management, Inc. a newly-formed, wholly-owned insurance captive subsidiary of Reliant Bancorp, Inc. that began operations on June 1, 2020, is a Tennessee-based captive insurance company which insures Reliant Bancorp and the Bank against certain risks unique to their operations and for which insurance may not be currently available or economically feasible in today's insurance marketplace. It pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. Reliant Risk Management, Inc. is subject to regulations of the State of Tennessee and undergoes periodic examinations by the Tennessee Department of Commerce and Insurance.

Critical Accounting Policies

The accounting principles we follow and our methods of applying these principles conform to U.S. GAAP and with general practices within the banking industry. There have been no significant changes to our critical accounting policies as described in our Annual Report on Form 10-K for the year ended December 31, 2019. The following is a brief summary of the more significant policies.

Principles of Consolidation

The Company's consolidated financial statements as of and for the periods presented include the accounts of Reliant Bancorp, the Bank, TRUPS, Holdings, Risk, and RMV. All significant intercompany balances and transactions have been eliminated in consolidation. As described in Note 12 to our consolidated financial statements, effective January 1, 2020, Reliant Bancorp and TCB Holdings merged and effective April 1, 2020, Reliant Bancorp and First Advantage Bancorp merged.

During 2011, the Bank and another entity organized RMV. Under the RMV operating agreement, the non-controlling member receives 70% of the cash flow distributions of RMV, and the Bank receives 30% of the cash flow distributions, once the non-controlling member recovers its capital contributions to RMV. The non-controlling member is required to fund RMV’s losses in arrears via additional capital contributions to RMV. As of June 30, 2020, RMV's cumulative losses to date totaled $15,803. RMV will have to generate net income of at least this amount before the Bank will participate in future cash flow distributions.

Purchased Loans

The Company maintains an allowance for loan losses on purchased loans based on credit deterioration subsequent to the acquisition date. In accordance with the accounting guidance for business combinations, because we recorded all loans acquired from TCB Holdings and FABK at fair value as of the dates of the TCB Holdings Transaction and the FABK Transaction, respectively, we did not establish an allowance for loan losses on any of the loans we purchased as of the acquisition date as any credit deterioration evident in the loans was included in the determination of the acquisition date fair values. For purchased credit-impaired loans accounted for under ASC 310-30, management is required to establish an allowance for loan losses subsequent to the dates of acquisition by re-estimating expected cash flows on these loans on a quarterly basis, with any decline in expected cash flows due to a credit triggering impairment recorded as provision for loan losses. The allowance for loan losses established is the excess of the loan’s carrying value over the present value of projected future cash flows, discounted at the current accounting yield of the loan or the fair value of collateral (less estimated costs to sell) for collateral dependent loans. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change. While the determination of specific cash flows involves estimates, each estimate is unique to the individual loan, and none is individually significant. For non-purchased credit-impaired loans acquired in the TCB Holdings Transaction and the FABK Transaction that are accounted for under ASC 310-20, the historical loss estimates are based on the historical losses experienced by the Bank for loans with similar characteristics as those acquired other than purchased credit-impaired loans. The Bank records an allowance for loan losses only when the calculated amount exceeds the remaining credit mark established at acquisition.

Table of Contents

Allowance for Loan Losses

The allowance for loan losses ("allowance") is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using historical loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, current economic conditions (national and local), and other factors such as changes in interest rates, portfolio concentrations, changes in the experience, ability, and depth of the lending function, levels of and trends in charged-off loans, recoveries, past-due loans and volume and severity of classified loans. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The entire allowance is available for any loan that, in management’s judgment, should be charged off as uncollectible.

A loan is impaired when full payment under the loan terms is not expected. All classified loans and loans on nonaccrual status are individually evaluated for impairment. Factors considered in determining if a loan is impaired include the borrower’s ability to repay amounts owed, collateral deficiencies, the risk rating of the loan and economic conditions affecting the borrower’s industry, among other things. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value (less estimated costs to sell) of collateral if repayment is expected solely from the collateral. Interest payments on impaired loans are typically applied to principal unless the principal amount is deemed fully collectible, in which case interest is recognized on a cash basis. When recognition of interest income on a cash basis is appropriate, the amount of income recognized is limited to what would have been accrued on the remaining principal balance at the contractual rate. Cash payments received over this limit, and not applied to reduce the loan's remaining principal balance, are recorded as recoveries of prior charge-offs until these charge-offs have been fully recovered.

Fair Value of Financial Instruments

Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note to our consolidated financial statements. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.

Coronavirus (COVID-19) Impact

The following is a description of the impact the novel coronavirus (COVID-19) pandemic is having on our financial condition and results of operations and certain risks to our business that the pandemic creates or exacerbates.

Operational Impact

As part of our pandemic response, we have encouraged a significant portion of our employees to work from home. We have also extended virtual medical coverage to all employees as well as provided pay to employees who may have been exposed as they quarantine at home. We are encouraging virtual meetings and conference calls in place of in-person meetings, including our earnings call and investor meetings which were held virtually this quarter. We are promoting social distancing, frequent hand washing, thorough disinfection of all surfaces, and the use of masks or nose and mouth coverings have been mandated in all of our locations. We have selected branches in each market open for limited hours, with the other branches closed except for advance appointments for essential services. Banking center drive-ups, ATMs and online/mobile banking services continue to operate. It remains undetermined how long our banking centers will operate at these service levels. Infection rates in the communities we serve vary by region and we will make prudent decisions for the safety of our colleagues and our clients.

Loan Modifications

Section 4013 of the CARES Act, which was signed into law on March 27, 2020, provides that financial institutions may elect to account for loan modifications occurring between March 1, 2020, and the earlier of December 31, 2020 and the 60th day after the end of the COVID-19 national emergency declared by President Trump, which are due to COVID-19 and where the borrower was current on contractual payments as of December 31, 2019, as not TDRs. Additionally, on April 7, 2020, federal banking regulators issued an Interagency Statement on Loan Modifications by Financial Institutions Working with Customers Affected by the Coronavirus (Revised), which replaced a prior interagency statement predating the CARES Act. The revised interagency statement encourages financial institutions to work prudently with borrowers that may be unable to meet their contractual payment obligations because of the effects of COVID-19. It also addresses loan modifications not meeting the

Table of Contents

criteria set forth in Section 4013 of the CARES Act or for which financial institutions elect not to apply Section 4013. With respect to these loan modifications, the revised interagency statement provides that short-term (e.g. six month) modifications made on a good faith basis in response to COVID-19 to borrowers who were current on their contractual payments at the time of implementation of a modification program are not TDRs.

Through July 29, 2020, the Company had applied this guidance to approve initial modifications In April and May for loans with principal balances of $530.7 million. The majority of these modifications involved extensions of up to three months of either interest-only periods or full payment deferrals. Through August 5, 2020, further modifications were approved for $39.0 million of the loans previously modified. Additional modifications are likely to be executed in the third quarter of 2020.

Paycheck Protection Program (PPP) and Liquidity

The CARES Act provided for over $2.0 trillion in emergency economic relief to individuals and businesses impacted by the COVID-19 pandemic. The CARES Act authorized the SBA to administer new loan programs, including, but not limited to, the guarantee of loans under a new 7(a) loan program called the "Paycheck Protection Program".

An eligible business can apply for a PPP loan in an amount up to the lesser of: (1) 2.5 times its average monthly “payroll costs” or (2) $10.0 million. PPP loans have: (a) an interest rate of 1.0%; (b) a two-year loan term to maturity for loans made prior to June 5, 2020, or a five-year loan term to maturity for loans made on or after June 5, 2020; and (c) principal and interest payments deferred for six months from the date of disbursement. The SBA will guarantee 100% of the PPP loans made to eligible borrowers. The entire principal amount of the borrower’s PPP loan, including any accrued interest, is eligible to be reduced by the loan forgiveness amount under the PPP so long as employee and compensation levels of the business are maintained and 60% of the loan proceeds are used for payroll expenses, with the remaining 40% of the loan proceeds used for other qualifying expenses.

Through June 30, 2020, we had received SBA authorizations for PPP loans totaling $83,291 and related fees of $3,301. Participation in the PPP will likely have an impact on the Company's asset mix and net interest margin for the remainder of 2020. At June 30, 2020, we had $98,000 in federal funds lines available and $293,800 of available borrowing capacity from correspondent banks. In addition, the Federal Reserve has implemented a liquidity facility available to financial institutions participating in the PPP. As such, the Company believes it has sufficient liquidity sources to continue to provide this important service to local businesses if and as additional funds are appropriated for the PPP.

As of June 30, 2020, the Bank's capital ratios were in excess of all regulatory requirements. While we believe that we have sufficient capital to withstand an extended economic recession brought about by the COVID-19 pandemic, our reported and regulatory capital ratios could be adversely impacted by future credit losses.

Asset Impairment

At June 30, 2020, our level of non-performing assets was not materially impacted by the economic pressures of COVID-19. We are closely monitoring credit risk and our exposure to increased loan losses resulting from the impact of COVID-19 on our commercial and other clients.

At this time, we do not believe there exists any impairment to our intangible assets, long-lived assets, right of use assets, or available-for-sale investment securities due to the COVID-19 pandemic. It is uncertain whether prolonged effects of the COVID-19 pandemic will result in future impairment charges related to any of the aforementioned assets.

Risks

See Part II , Item 1A. "Risk Factors" for more information.

Allowance for Loan Loss

We are in regular communication with our customers to gain a better understanding of our highest risk exposures and probable defaults. In the second quarter of 2020 we recorded a provision expense of $3.0 million, all of which can be attributed to increased risk factors related to the COVID-19 pandemic. Our losses year-to-date remain low but we continue to build reserves as we anticipate future downgrades and defaults may eventually result in losses.

Earnings

Net income attributable to common shareholders amounted to $7,868, or $0.48 per basic share, and $7,653, or $0.54 per basic share, for the three and six months ended June 30, 2020, respectively, compared to $4,239, or $0.38 per basic share, and $8,063, or $0.71 per basic share, for the same periods in 2019, respectively. Diluted net income attributable to common shareholders was $0.48 and $0.54 per share for the three and six months ended June 30, 2020, respectively, compared to $0.38 and $0.71 per share for the three and six months ended June 30, 2019, respectively. The major components contributing to the change when compared to the prior year periods are an increase of 116.9% and 72.6% in net interest income for the three and six months ended June 30, 2020, respectively, and an increase of 63.9% and 66.2% in noninterest income for the three and six months ended June 30, 2020, respectively, and partially offset by an increase of 69.6% and 61.8% in noninterest expense (mainly driven by merger expenses) for the three and six months ended June 30, 2020, and an increase of $2,800 and $5,700 in provision for loan losses for the three and six months ended June 30, 2020, compared to the same periods in 2019.

Non-GAAP Financial Measures

This Form 10-Q contains certain financial measures that are considered "non-GAAP financial measures" and should be read along with the accompanying tables. Generally, a non-GAAP financial measure is a numerical measure of a company's financial performance, financial position, or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presente din accordance with U.S. GAAP. Management believes that non-GAAP financial measures provide a greater understanding of ongoing performance and operations and enhance comparability accross periods. Non-GAAP financial measures should not, however, be considered as an alternative to any measure of performance or financial condition as determined in accordance with U.S. GAAP, and readers should consider the Company’s performance and financial condition as reported under U.S. GAAP and all other relevant information when assessing the performance or financial condition of the Company. Non-GAAP financial measures have limitations as analytical tools, and readers should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under U.S. GAAP. Non-GAAP financial measures presented by the Company may not be comparable to non-GAAP financial measures (even those with the same or similar names) presented by other companies.

Company management uses, and believes that investors benefit from referring to, the following non-GAAP financial measures, among others, to assess the Company's operating results and trends: (i) tax-equivalent net interest income; (ii) adjusted net interest income; (iii) adjusted net interest margin; (iv) adjusted net income attributable to common shareholders; (v) adjusted net income attributable to common shareholders, per diluted share; (vi) adjusted return on average assets; (vii) adjusted return on average stockholders' equity; (viii) average tangible common equity; and, (ix) return on average tangible common equity (ROATCE); and (x) adjusted return on average tangible common equity. In the following table, the Company has provided a reconciliation of these non-GAAP financial measures to their most comparable GAAP financial measures.

Net Interest Income

Net interest income represents the amount by which interest earned on various earning assets exceeds interest accrued on deposits and other interest-bearing liabilities and is the most significant component of our revenues. The following table sets forth the amount of our average balances, interest income or interest expense for each category of interest-earning assets and interest-bearing liabilities and the average interest rate for interest-earning assets and interest-bearing liabilities, net interest rate spread and net interest margin for the three and six months ended June 30, 2020, and 2019 (dollars in thousands):

Table Assumptions—Average loan balances are inclusive of nonperforming loans. Interest income and yields computed on tax-exempt instruments are on a tax-equivalent basis including a state tax credit included in loan yields of $779 and $1,083 for the three and six months ended June 30, 2020 and $300 and $600 for the same periods in 2019. Net interest spread is calculated as the yields realized on interest-bearing assets less the rates paid on interest-bearing liabilities. Net interest margin is the result of net interest income calculated on a tax-equivalent basis divided by average interest earning assets for the period. Changes in net interest income are attributed to either changes in average balances (volume change) or changes in average rates (rate change) for earning assets and sources of funds on which interest is received or paid. Volume change is calculated as change in volume times the previous rate while rate change is change in rate times the previous volume. Changes not due solely to volume or rate changes have been allocated to volume change and rate change in proportion to the relationship of the absolute dollar amounts of the change in each category.

Analysis—For the three and six months ended June 30, 2020, we recorded net interest income on a tax-equivalent basis of approximately $31,117 and $48,925, respectively, which resulted in a net interest margin (net interest income divided by the average balance of interest-earning assets) of 4.58% and 4.16%, respectively. For the three and six months ended June 30, 2019, we recorded net interest income on a tax-equivalent basis of approximately $14,556 and $28,776, respectively, which resulted in a net interest margin of 3.57% and 3.60%, respectively.

Our year-over-year average loan volume increased by approximately 55.7% for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 and was mainly driven by the TCB Holdings Transaction and FABK Transaction. Our combined loan and loan fee yield increased from 5.43% to 5.98% for the three months ended June 30, 2020 compared to the

same period in 2019 and increased from 5.41% to 5.67% for the six months ended June 30, 2020 compared to the same period in 2019. The increased yield for the three and six months ended June 30, 2020 is primarily attributable to the increased purchase accounting accretion from the two mergers as well as the increased fees from the PPP loans.

Our tax-equivalent yield on tax-exempt investments was 3.51% and 3.54% for the three and six months ended June 30, 2020 compared to 3.77% and 3.82% for the same periods in 2019. Our year-over-year average tax-exempt investment volume decreased by 13.3% for the six months ended June 30, 2020 compared to the same period in 2019 due to investment sales in the fourth quarter of 2019. Our year-over-year average taxable securities volume increased by 6.0% for the six months ended June 30, 2020 compared to the same period in 2019.

Our cost of funds decreased to 0.91% and 1.08% from 1.52% and 1.48%, respectively, for the three and six months ended June 30, 2020 compared to the same periods in 2019. The decrease in our cost of funds was primarily driven by an across the board decrease in the cost of our interest-bearing deposits and other interest-bearing liabilities due to the recent decrease in rates by the Federal Reserve. We experienced an 81.7% increase in our average noninterest-bearing deposits for the six months ended June 30, 2020 when compared to the same period in 2019, which is mainly attributable to the TCB Holdings Transaction and FABK Transaction.

The Bank strives to maintain a strong net interest margin that is insulated from changes in market interest rates. Our net interest margin, while generally considered fairly neutral, is currently subject to slightly expand in a rising rate environment and slightly contract in a falling rate environment. The Company has interest rate floors on certain loans and those floors will mitigate further declines in interest rates.

Provision for Loan Losses

We recorded a provision of $3,000 and $5,900 for loan losses for the three and six months ended June 30, 2020, respectively, compared to $200 for the three and six months ended June 30, 2019. The increase in provision expense for the three and six months ended June 30, 2020 can be primarily attributed to the recent downturn in the economy due to COVID-19 while a portion is due to the growing loan portfolio. See “Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Comparison of Balance Sheets at June 30, 2020 and December 31, 2019 - Allowance for Loan Losses” included herein for further analysis of the provision for loan losses.

Noninterest Income

Our noninterest income is composed of several components, some of which vary significantly between periods. The following is a summary of our noninterest income for the three and six months ended June 30, 2020, and 2019 (dollars in thousands):

The most significant reasons for the changes in total noninterest income during the three and six months ended June 30, 2020 compared to the same periods in 2019 are the fluctuation in gains on mortgage loans sold, net and the increase in service charges mainly attributable to the two mergers. These and other factors impacting noninterest income are discussed further below.

Service charges and fees on deposit accounts have increased due to the TCB Holdings Transaction, the FABK Transaction, and the concentrated effort in attracting noninterest-bearing deposits, with the majority of the 47.5% and 42.3% increases for the three and six months ended June 30, 2020, respectively, deriving from the increases in our debit card fees.

Securities gains and losses often fluctuate from period to period and can sometimes be attributable to various balance sheet risk strategies. During the six months ended June 30, 2020, the Company sold securities totaling $103,668 with a gain of $327. During the six months ended June 30, 2019, the Company sold securities classified as available for sale totaling $52,434 with a gain of $306.

Generally, mortgage-related revenue increases in lower interest rate environments and more robust housing markets and decreases in rising interest rate environments and more challenging housing markets. Mortgage-related revenue will fluctuate from quarter to quarter as the rate environment changes and as changes occur with our mortgage operations including but not limited to the number of loan originators employed and the channels available for loan sales of RMV’s products in the secondary markets. Gains on mortgage loans sold, net, amounted to $2,248 and $3,821 for the three and six months ended June 30, 2020, respectively, compared to $1,225 and $1,785 for the same periods in the prior year. The increase in gains for the three and six months ended June 30, 2020 when compared to the same periods in 2019 is primarily driven by the increase in volume in the traditional mortgage market. As discussed further in the notes to our consolidated financial statements, gains on mortgage loans sold are generally recognized at the time of a loan sale corresponding to the transfer of risk. The secondary market for the sale of non-qualified mortgage loans experienced a disruption related to the COVID-19 pandemic starting in 2020. As a result, the Company's held-for-sale portfolio increased by $64.1 million from December 31, 2019 to June 30, 2020. Management expects this market to recover but has elected to halt sales until bids have returned to acceptable levels.

During the three and six months ended June 30, 2020, there were gains of $11 and $25, respectively, due to the sale of other real estate compared to no gains in the same periods in 2019.

Noninterest income also includes appreciation in the cash surrender value of bank-owned life insurance, which was $392 and $687 for the three and six months ended June 30, 2020, respectively, compared to $277 and $555 for the same periods in 2019. The increases for both periods are attributable to the recent mergers. The assets that support these policies are administered by the life insurance carriers and the income we receive (i.e., increases or decreases in the cash surrender value of the policies) is dependent upon the returns the insurance carriers are able to earn on the underlying investments that support the policies. Earnings on these policies generally are not expected to be taxable.

Noninterest Expense

The following is a summary of our noninterest expense for the three and six months ended June 30, 2020 and 2019 (dollars in thousands):

			Three Months Ended June 30,												Percent Increase			Six Months Ended June 30,												Percent Increase

Occupancy			2,026			1,358						49.2		%	3,512			2,710						29.6		%
Information technology			2,027			1,575						28.7		%	3,846			2,985						28.8		%
Advertising and public relations			228			275						(17.1)		%	581			529						9.8		%
Audit, legal and consulting			680			690						(1.4)		%	1,158			1,486						(22.1)		%
Federal deposit insurance			441			249						77.1		%	777			444						75.0		%
Merger expenses			2,632			1						263,100.0		%	6,818			3						227,166.7		%

Total noninterest expense			$	22,264		$	13,126					69.6		%	$	41,862		$	25,872					61.8		%

Noninterest expense increased by $9,138 and $15,990, or 69.6% and 61.8%, for the three and six months ended June 30, 2020, respectively, compared to the same periods in 2019 driven by an increase in merger expenses and salaries and employee benefits. The three and six-months period ended June 30, 2020 have been impacted by the TCB Holdings Transaction and the FABK Transaction which have resulted in additions to staff, additional vendor relationships and investments in technology. These and other factors impacting noninterest expense are discussed further below.

Salaries and employee benefits increased by $4,758 and $6,730 or 61.7% and 45.0% for the three and six months ended June 30, 2020, respectively, compared to the same periods in 2019. This increase is primarily attributable to the TCB Holdings Transaction in the first quarter of 2020 and FABK Transaction in the second quarter of 2020 increasing full-time employee equivalents by 21 and 119, respectively, as well as our year over year growth and severance for two executives. We believe the staffing level normalized by the end of the second quarter.

Occupancy costs increased $668 or 49.2% and $802 or 29.6% during the three and six months ended June 30, 2020, respectively, compared to the same periods in 2019 mainly due to the TCB Holdings Transaction and FABK Transaction, as well as the additional leases for mortgage production offices in Memphis and Chattanooga, Tennessee and two offices in Little Rock, Arkansas, and one in Crossett, Arkansas which opened during August 2019.

Information technology costs increased by $452 or 28.7% and $861 or 28.8% when comparing the three and six months ended June 30, 2020, respectively, to the comparable periods in 2019. This increase is mainly attributable to increased costs due to increasing volume of accounts and transactions as well as our continued investment in information security and other technology, and our increase in locations mentioned in the previous paragraph. Both the volume and location increases are primarily due to the TCB Holdings Transaction, FABK Transaction, and the expansion of RMV.

Advertising and public relations costs decreased by $47 or 17.1% for the three-month period ended June 30, 2020 and increased by $52 or 9.8% for the six months ended June 30, 2020 when comparing to the same periods in 2019. These costs fluctuate based on the timing of campaigns and promotions of the Company and the current changes were primarily attributable to the fluctuation of promotional expenses and advertising for RMV.

Audit, legal and consulting costs decreased by $10 or 1.4%, and $328 or 22.1%, respectively, when comparing the three and six months ended June 30, 2020, to the same periods in 2019. This fluctuation is mainly attributable to the decrease of legal and consulting fees incurred by RMV and partially offset by increased fees related to special projects by the Company.

Our FDIC deposit insurance expense is based on our outstanding liabilities for the period multiplied by a factor determined by the FDIC, mainly driven by our most recent regulatory rating and certain financial performance factors. Our FDIC expense increased by $192 and $333 for the three and six months ended June 30, 2020, compared to the same periods in 2019. This increase is primarily the result of our increase in deposits due to the TCB Holdings Transaction and the FABK Transaction.

Merger-related expenses increased by $2,631 and $6,815 for the three and six months ended June 30, 2020 when compared to the same periods in 2019. These costs are considered one-time expenses which for 2020 are associated with the TCB Holdings Transaction and the FABK Transaction. We anticipate no further significant merger expenses to be incurred in relation to these two transactions.

Other operating expenses increased by $494 or 38.8% and $725 or 26.4% for the three and six months ended June 30, 2020 compared to the same period in 2019, mainly due to an increase in amortization of core deposit intangibles and franchise taxes due to the TCB Holdings Transaction and FABK Transaction.

Income Taxes

During the three and six months ended June 30, 2020, we recorded consolidated income tax expense of $1,634 and $724, respectively, compared to $501 and $873, respectively, for the three and six months ended June 30, 2019. The Company files separate federal tax returns for RMV and the bank segment. The taxable income or losses of the mortgage banking operations are included in the respective franchise and excise returns of the Bank and non-controlling member for federal purposes.

Our income tax expense attributable to shareholders for the three and six months ended June 30, 2020, reflects an effective income tax rate of 17.4% and 9.7%, respectively, (exclusive of a tax benefit from our mortgage banking operations of $27 and $96 for the three and six months ended June 30, 2020, respectively, on pre-tax losses of $415 and $1,460 for the three and six months ended June 30, 2020, respectively), compared to 12.5% and 11.9% for the same periods in 2019 (exclusive of a tax benefit of $106 and $214 on pre-tax losses of $1,661 and $3,312, respectively, from our mortgage banking operations for the comparable periods in 2019). Additionally, our effective tax rate for the three months ended June 30, 2020 is higher than the same period in 2019 primarily due to the decrease in our tax-exempt income and the proportion of tax-exempt income to income before taxes. Our effective tax rate for the six months ended June 30, 2020 decreased from the same period in 2019 due to the amount of merger expenses in 2020 and an increase in the proportion of tax-exempt income to taxable income. The Company's tax-exempt income from securities, loans and earnings from bank-owned life insurance contracts as well as state tax credits related to loans to encourage economic development impact the effective tax rate.

Non-controlling Interest in Net Loss of Subsidiary

Our non-controlling interest in net loss of subsidiary is solely attributable to the RMV minority interest. The Bank has a 51% voting interest in this venture, but under the terms of the related operating agreement, the non-controlling member receives 70% of the cash flow distributions of RMV and the Bank receives 30% of any cash flow distributions, after the non-controlling member recovers its aggregate capital contributions. The non-controlling member is required to fund RMV's losses, in arrears, via additional capital contributions. RMV had a net loss of $388 and $1,364 for the three and six months ended June 30, 2020, respectively, compared to a net loss of $1,555 and $3,098 for the same periods in 2019. The decreased loss for the three and six months ended June 30, 2020 when compared to the same period in 2019 is mainly attributable to the decrease in expense relating to the start-up of the correspondent line of business in 2019. Also, see Note 9 to our consolidated financial statements for segment reporting.

COMPARISON OF BALANCE SHEETS AT JUNE 30, 2020 AND DECEMBER 31, 2019

Overview

The Company’s total assets were $2,991,612 at June 30, 2020 and $1,898,467 at December 31, 2019. Assets increased by 57.6% from December 31, 2019 to June 30, 2020, primarily due to acquisition activity which increased total loans by $793,289 making up 73% of the total increase in assets. Total liabilities were $2,696,069 at June 30, 2020 and $1,674,714 at December 31, 2019, an increase of 61.0%. The increase in liabilities from December 31, 2019 to June 30, 2020, was substantially attributable to the increase in deposits of $946,273, or 59.7%, and an increase in FHLB advances of $38,384 during the period. These changes were materially impacted by the TCB Holdings Transaction as well as the FABK Transaction. These and other components of our consolidated balance sheets are discussed further below.

Loans

Lending-related income is the largest component of our net interest income and is a major contributor to profitability. The loan portfolio is the largest component of earning assets, and it, therefore, generates the largest portion of revenues. The absolute volume of loans and the volume of loans as a percentage of earning assets is an important determinant of net interest margin as loans are expected to produce higher yields than securities and other earning assets. As previously described, the competition for quality loans in our markets has remained strong. Our goal is to steadily grow our loan portfolio, focusing on quality. This is not always possible for various reasons, including but not limited to scheduled maturities or early payoffs exceeding new loan volume, as well as economic conditions. Early payoffs typically increase in falling rate environments as customers identify advantageous opportunities for refinancing. We have been adding experienced lending officers to our staff to help with loan growth. We have expanded our Middle Tennessee footprint into Cheatham County with the TCB Holdings Transaction. The FABK Transaction expanded our footprint into Montgomery County as well as enhanced our presence in Davidson County. Additionally, the FABK Transaction diversified our loan portfolio with the addition of loans related to manufactured housing. Total loans, net, at June 30, 2020, and December 31, 2019, were $2,299,087 and $1,397,374, respectively. This represented an increase of 64.5% from December 31, 2019 to June 30, 2020. As part of the increase in loans, $171,445 were acquired in connection with the first quarter TCB Holdings Transaction and $622,423 were acquired in connection with the second quarter FABK Transaction.

Consumer loans mainly consist of loans to individuals for household, family, and other personal expenditures under revolving credit plans, credit cards, and automobile and other consumer loans. Our consumer loans experienced an increase from December 31, 2019, to June 30, 2020, of 1,060.0% primarily due to $177,016 in loans to finance manufactured homes that are not secured by real estate acquired in the FABK Transaction.

Other loans consist mainly of loans to states and political subdivisions and loans to other depository institutions and experienced a decrease of 45.3% from December 31, 2019 to June 30, 2020 due to loan payments.

The repayment of loans is a source of additional liquidity for us. The following table sets forth the loans repricing or maturing within specific intervals at June 30, 2020, excluding unearned net fees and costs.

			One Year or Less						One to Five Years						Over Five Years						Total
Gross loans			$	609,148					$	1,087,892					$	625,469					$	2,322,509
Fixed interest rate																					$	1,376,801
Variable interest rate																					945,708
Total																					$	2,322,509

The information presented in the above table is based upon the contractual maturities or next repricing date of the individual loans, including loans which may be subject to renewal at their contractual maturity. Renewal of such loans is subject to review and credit approval, as well as modification of terms upon their maturity. Consequently, we believe this treatment presents fairly the maturity and repricing structure of the loan portfolio.

Allowance for Loan Losses

At June 30, 2020, the allowance for loan losses was $18,237 compared to $12,578 at December 31, 2019. The allowance for loan losses as a percentage of total loans was 0.79% at June 30, 2020 compared to 0.89% at December 31, 2019.

Nonperforming Assets

Nonperforming assets consists of nonperforming loans plus real estate acquired through foreclosure or deed in lieu of foreclosure and other repossessed collateral. Nonperforming loans by definition consists of nonaccrual loans and loans past due 90 days or more and still accruing interest. When we place a loan on nonaccrual status, interest accruals cease and uncollected interest is reversed and charged against current income. The interest on these loans is accounted for on the cash-basis, or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured, which generally includes a minimum performance of six months.

The following table provides information with respect to the Company’s nonperforming assets.

			June 30, 2020						December 31, 2019

Investment Securities and Other Earning Assets

The investment securities portfolio is intended to provide the Bank with adequate liquidity, flexible asset/liability management and a source of stable income. The portfolio is structured with investment grade holdings and consists of securities classified as available-for-sale. All available-for-sale securities are carried at fair value and may be used for liquidity purposes should management deem it to be in our best interest. Unrealized gains and losses on this portfolio are excluded from earnings, but are reported as other comprehensive income in a separate component of stockholders’ equity, net of income taxes. Premium amortization and discount accretion are recognized as adjustments to interest income using the interest method. Realized gains or losses on sales are based on the net proceeds and the adjusted carrying value amount of the securities sold using the specific identification method.

Securities totaled $249,014 at June 30, 2020, in comparison to the $260,293 in securities balances at December 31, 2019. This decrease can largely be attributed to the Company's use of these funds to promote loan growth and reduce wholesale funding during the period. Activity during the six months ended June 30, 2020 includes the sale of $103,668 of securities, most of which were acquired as part of the TCB Holdings Transaction and FABK Transaction, as well as $9,635 of principal paydowns, calls, and maturities. In connection with the TCB Holdings Transaction and FABK Transaction, management determined that it would be beneficial to liquidate those portfolios and utilize those funds for loan demand and other uses.

Restricted equity securities totaled $17,509 and $11,279 at June 30, 2020, and December 31, 2019, respectively, and consist of FRB and FHLB stock.

Premises and Equipment

Premises and equipment, net, totaled $34,194 at June 30, 2020 compared to $21,064 at December 31, 2019, a net increase of $13,130, or 62.3%. Premises and equipment purchases amounted to approximately $2,566 during the six months ended June 30, 2020 and were mainly incurred for additional leasehold improvements for our branches and new mortgage locations while depreciation expense amounted to $1,327. As part of the TCB Holdings Transaction, $6,427 of premises and equipment were acquired effective January 1, 2020. Effective April 1, 2020, premises and equipment of $7,965 were acquired in the FABK Transaction. At June 30, 2020, we operated from 27 retail banking locations, one standalone loan production office, as well as five standalone mortgage loan production offices. At June 30, 2020, our branches were located in Cheatham, Davidson, Hamilton, Hickman, Maury, Montgomery, Robertson, Rutherford, Sumner and Williamson counties in Tennessee. As of June 30, 2020, our mortgage loan production offices were located in Brentwood, Chattanooga, Hendersonville, and Memphis, Tennessee as well as two in Little Rock, Arkansas and one in Crosset, Arkansas. Our loan production office acquired through the FABK Transaction is located in Knox County, Tennessee.

Deposits

Deposits represent the Company’s largest source of funds. The Company competes with other bank and non-bank institutions for deposits, as well as with a growing number of non-deposit investment alternatives available to depositors such as money market funds and other brokerage investment products. Challenges to deposit growth include interest rate changes on deposit products given movements in the interest rate environment and other competitive pricing pressures, and customer preferences regarding higher-costing deposit products or non-deposit investment alternatives.

At June 30, 2020, total deposits were $2,530,062, an increase of $946,273, or 59.7%, compared to $1,583,789 at December 31, 2019. During the six months ended June 30, 2020, noninterest bearing demand deposits increased by $259,611, interest-bearing demand deposits increased by $135,992, savings and money market deposits increased by $362,781, and time deposits increased by $187,889. The primary driver of the increase in deposits is attributable to the deposits acquired in the TCB Holdings Transaction which totaled $210,538 coupled with those acquired in the FABK Transaction which totaled $608,690. During the six months ending June 30, 2020, management shifted from using brokered time deposits to transactional deposits and to using FHLB advances.

Market and Liquidity Risk Management

Our objective is to manage assets and liabilities to provide a satisfactory, consistent level of profitability within the framework of established liquidity, loan, investment, borrowing, and capital policies. Our Asset Liability Management Committee ("ALCO") is charged with the responsibility of monitoring these policies, which are designed to ensure acceptable composition of asset/liability mix. Two critical areas of focus for ALCO are interest rate sensitivity and liquidity risk management.

Interest Rate Sensitivity—Interest rate sensitivity refers to the responsiveness of interest-earning assets and interest-bearing liabilities to changes in market interest rates. In the normal course of business, we are exposed to market risk arising from fluctuations in interest rates. ALCO measures and evaluates the interest rate risk so that we can meet customer demands for various types of loans and deposits. ALCO determines the most appropriate amounts of off-balance sheet items to maximize long-term earnings and mitigate interest rate risk. Measurements we use to help us manage interest rate sensitivity include a gap analysis, an earnings simulation model and an economic value of equity model. These measurements are used in conjunction with competitive pricing analysis and are further described below.

Interest Rate Sensitivity Gap Analysis—The rate sensitive position, or gap, is the difference in the volume of rate-sensitive assets and liabilities, at a given time interval, including both floating rate instruments and instruments which are approaching maturity. The measurement of our interest rate sensitivity, or gap, is one of the three principal techniques we use in our asset/liability management effort.

Our policy is to have 12 and 24-month cumulative repricing gaps that do not exceed 25% of assets. We slightly exceeded our policy as of June 30, 2020 for the 12-month cumulative repricing gap. Although we do monitor our gap on a periodic basis, we recognize the potential shortcomings of such a model. The static nature of the gap schedule makes it difficult to incorporate changes in behavior that are caused by changes in interest rates. Also, although the periods of estimated and contractual repricing are identified in the analysis, the extent of repricing is not modeled in the gap schedule (i.e. whether repricing is expected to move on a one-to-one or other basis in relationship to the market changes simulated). For these reasons and as a result of other model shortcomings, we rely more heavily on the earnings simulation model and the economic value of equity model discussed further below.

Earnings Simulation Model—We believe interest rate risk is effectively measured by our earnings simulation modeling. Earning assets, interest-bearing liabilities and off-balance sheet financial instruments are combined with simulated forecasts of interest rates for the next 12 months and 24 months. To limit interest rate risk, we have guidelines for our earnings at risk which seek to limit the negative variances of net interest income in instantaneous changes to interest rates. We also periodically monitor simulations based on various rate scenarios such as non-parallel shifts in market interest rates over time. For changes up or down in rates from a flat interest rate forecast over the next 12 and 24 months, our estimated change in net interest income as well as our policy limits are as follows:

Instantaneous, Parallel Change in Prevailing Interest Rates Equal to						Estimated Change in Net Interest Income and Policy of Maximum Percentage Decline in Net Interest Income
						Next 12																		Next 24
						Months																		Months
						Estimate						Policy						Estimate						Policy
-200 bp						(0.5)%						(15)%						(1.4)%						(15)%

+300 bp						3.5%						(20)%						8.8%						(20)%
+400 bp						5.6%						(25)%						12.3%						(25)%

We were in compliance with our earnings simulation model policies as of June 30, 2020, indicating what we believe to be a fairly neutral interest-rate risk profile.

Economic Value of Equity Model—Our economic value of equity model measures the extent that estimated economic values of our assets, liabilities and off-balance sheet items will change as a result of interest rate changes. Economic values are determined by discounting expected cash flows from assets, liabilities and off-balance sheet items, which establishes a base case economic value of equity.

To help monitor our related risk, we have established the following policy limits regarding simulated changes in our economic value of equity:

Instantaneous, Parallel Change in Prevailing Interest Rates Equal to						Maximum Percentage Decline in Economic Value of Equity from the Economic Value of Equity at Currently Prevailing Interest Rates
±100bp						15%
±200 bp						25%
±300 bp						30%
±400 bp						35%
Non-parallel shifts						35%

At June 30, 2020, our model results indicated that we were within these policy limits.

Each of the above analyses may not, on its own, be an accurate indicator of how our net interest income will be affected by changes in interest rates. Income associated with interest-earning assets and costs associated with interest-bearing liabilities may not be affected uniformly by changes in interest rates. In addition, the magnitude and duration of changes in interest rates may have a significant impact on net interest income. For example, although certain assets and liabilities may have similar maturities or periods of repricing, they may react in different degrees to changes in market interest rates. Interest rates on certain types of assets and liabilities fluctuate in advance of changes in general market rates, while interest rates on other types may lag behind changes in general market rates. In addition, certain assets, such as adjustable rate loans, have features (generally referred to as interest rate caps and floors) which limit changes in interest rates. Prepayment and early withdrawal levels also could deviate significantly from those assumed in calculating the maturity of certain instruments. The ability of many borrowers to service their debts also may decrease during periods of rising interest rates. Our ALCO reviews each of the above interest rate sensitivity analyses along with several different interest rate scenarios as part of its responsibility to provide a satisfactory, consistent level of profitability within the framework of established liquidity, loan, investment, borrowing, and capital policies.

Liquidity Risk Management —The purpose of liquidity risk management is to ensure that there are sufficient cash flows to satisfy loan demand, deposit withdrawals, and our other needs. Traditional sources of liquidity for a bank include asset maturities and growth in core deposits. A bank may achieve its desired liquidity objectives from the management of its assets and liabilities and by internally generated funding through its operations. Funds invested in marketable instruments that can be readily sold and the continuous maturing of other earning assets are sources of liquidity from an asset perspective. The liability base provides sources of liquidity through attraction of increased deposits and borrowing funds from various other institutions and sources.

Changes in interest rates also affect our liquidity position. We currently price deposits in response to market rates and our management intends to continue this policy. If deposits are not priced in response to market rates, a loss of deposits could occur which would negatively affect our liquidity position.

Scheduled loan payments are a relatively stable source of funds, but loan payoffs and deposit flows fluctuate significantly, being influenced by interest rates, general economic conditions, competition, and the actions of our customers. Additionally, debt security investments are subject to prepayment and call provisions that could accelerate their payoff prior to stated maturity. We attempt to price our deposit products to meet our asset/liability objectives consistent with local market conditions. Our ALCO is responsible for monitoring our ongoing liquidity needs. Our regulators also monitor our liquidity and capital resources on a periodic basis.

The Company has established a line of credit with the FHLB, which is secured by a blanket pledge of 1-4 family residential mortgages, multi-family residential, commercial real estate, and home equity loans, and available-for-sale securities. At June 30, 2020, FHLB advances totaled $49,121 compared to $10,737 as of December 31, 2019. This increase in FHLB advances generally correlates with a decrease in more expensive brokered deposits, contributing to an improved net interest margin.

At June 30, 2020, the scheduled maturities of our FHLB advances and interest rates were as follows (scheduled maturities will differ from scheduled repayments):

Scheduled Maturities						Amount						Weighted Average Rates
2020						$	31,100					0.40%
2021						12,905						2.36%
2022						454						1.22%
2023						4,105						2.37%
2024						557						2.51%
						$	49,121					1.11%

The Company has outstanding $23,000 of subordinated debentures associated with trust preferred securities issued by trusts that are affiliates of Reliant Bancorp, $10,000 of which is owned by a wholly-owned subsidiary of Reliant Bancorp. Reliant Bancorp has timely made its scheduled interest payments on these subordinated debentures since assumed in the first quarter of 2018.  As of June 30, 2020, Reliant Bancorp was current on all interest payments due related to its subordinated debentures. Reliant Bancorp has the right to defer the payment of interest on the subordinated debentures at any time, for a period not to exceed 20 consecutive quarters. During the period in which it is deferring the payment of interest on its subordinated debentures, the indentures governing the subordinated debentures provide that Reliant Bancorp cannot pay any dividends on its common stock or preferred stock. 

On December 13, 2019, Reliant Bancorp issued and sold $60.0 million in aggregate principal amount of its 5.125% Fixed-to-Floating Rate Subordinated Notes due 2029 (the “Subordinated Notes”). The Subordinated Notes will bear interest at an initial rate of 5.125%, payable semi-annually until December 15, 2024, at which time the Subordinated Notes will bear interest at a floating rate equal to the three-month Secured Overnight Financing Rate (“SOFR”) (provided, that in the event the three-month SOFR is less than zero, the three-month SOFR will be deemed to be zero), plus a spread of 376.5 basis points. If the three-month SOFR rises during the floating interest period, the cost of the Subordinated Notes will increase, thereby negatively affecting our net income.

Capital

Stockholders’ equity was $295,543 at June 30, 2020, an increase of $71,790, or 32.1%, from $223,753 at December 31, 2019. During the six months ended June 30, 2020, the Company completed the TCB Holdings Transaction which increased stockholders' equity $18,041 and the FABK Transaction which increased stockholders' equity $51,915. Net income also contributed to the increase by $7,653. This increase was primarily offset by dividends declared of $2,874, and other comprehensive loss of $3,945. Contributions from the noncontrolling interest of $1,364 were recognized in the six months ended June 30, 2020. The increase in stockholders' equity mitigated by the growth in the Bank's assets led to a decrease in the Bank’s June 30, 2020 Tier 1 leverage ratio to 10.23% compared with 10.30% at December 31, 2019. See other ratios discussed further below. Additionally, the subordinated debentures qualify as Tier 1 and Total risk-based capital for the Company. Common stock dividends of $2,935 were paid during the six months ended June 30, 2020.

On July 14, 2017, the Company filed a Registration Statement on Form S-3 to offer, issue and sell from time to time in one or more offerings any combination of (i) common stock, (ii) preferred stock, (iii) debt securities, (iv) depository shares, (v) warrants, and (vi) units, up to a maximum aggregate offering price of $75,000,000. The net proceeds from any offering will be used for general corporate purposes including acquisitions, capital expenditures, investments, and the repayment, redemption, or refinancing of indebtedness or other securities. Until allocated to such purposes it is expected that we will invest any proceeds in short-term, interest-bearing instruments or other investment-grade securities. The Securities and Exchange Commission declared the Registration Statement on Form S-3 effective on August 17, 2017, and the Registration Statement on Form S-3 will expire on August 17, 2020.

Banks as regulated institutions are required to maintain certain levels of capital. The Federal Reserve Board of Governors, the primary federal regulator for the Bank, has adopted minimum capital regulations or guidelines that categorize capital components and the level of risk associated with various types of assets. Financial institutions are expected to maintain a level of capital commensurate with the risk profile assigned to their assets in accordance with applicable regulations and guidelines. We regularly review our capital adequacy to ensure compliance with these regulations and guidelines and to help ensure that sufficient capital is available for current and future needs. It is management’s intent to maintain an optimal capital and leverage mix for growth and for shareholder returns.

Prompt corrective action regulations provide five bank capital classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At June 30, 2020, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since these notifications that management believes have changed the institution’s category. Actual and required capital amounts and ratios are presented below as of June 30, 2020 and December 31, 2019 for Reliant Bancorp and the Bank.

Effects of Inflation and Changing Prices

The accompanying consolidated financial statements have been prepared in accordance with U.S. GAAP, which requires the measurement of financial positions and operating results in terms of historical dollars without considering the change in the relative purchasing power of money over time due to inflation. Unlike most industrial companies, virtually all of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates generally have a more significant impact on the performance of a financial institution than the effects of general levels of inflation. Although interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services, increases in inflation generally have resulted in increased interest rates. In addition, inflation affects financial institutions’ cost of goods and services purchased, the cost of salaries and benefits, occupancy expense, and similar items. Inflation and related increases in interest rates generally decrease the market value of investments and loans held and may adversely affect liquidity, earnings, and stockholders’ equity. Commercial and other loan originations and refinancing tend to slow as interest rates increase, and can reduce our earnings from such activities.

Off-Balance Sheet Lending Arrangements

Off-balance sheet arrangements generally consist of unused lines of credit and standby letters of credit. Such commitments of the Company were as follows at June 30, 2020:

			June 30, 2020
Unused lines of credit			$	506,038
Standby letters of credit			18,176
Total commitments			$	524,214

Other Off-Balance Sheet Arrangements

The Company utilizes interest rate swaps to mitigate interest rate risk. The total notional amount of swap agreements was $179,605 and $129,605, respectively, at June 30, 2020 and December 31, 2019. At June 30, 2020 and December 31, 2019, the contracts had negative fair values totaling $10,795 and $2,708, respectively.

Emerging Growth Company Status

Reliant Bancorp is presently an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and may take advantage of certain exemptions from various reporting requirements that are applicable to public companies that are not emerging growth companies, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. In addition, even if Reliant Bancorp chooses to comply with the reporting requirements of public companies that are not emerging growth companies, Reliant Bancorp may avail itself of the reduced requirements applicable to emerging growth companies from time to time in the future, so long as Reliant Bancorp is an emerging growth company. Reliant Bancorp will remain an emerging growth company through the fiscal year ended December 31, 2020. Management cannot predict if investors will find Reliant Bancorp’s common stock less attractive because it will rely on these exemptions. If some investors find Reliant Bancorp’s common stock less attractive as a result, there may be a less active trading market for its common stock and Reliant Bancorp’s stock price may be more volatile.

Further, the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. Reliant Bancorp has elected to take advantage of the extended transition period that allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies, which means that the financial statements included in this filing, as well as the financial statements we will file in the future, will be subject to all new or revised accounting standards generally applicable to private companies. As a result, we will comply with new or revised accounting standards to the same extent that compliance is required for non-public companies.

PART II – OTHER INFORMATION

Item 1.  Legal Proceedings.

Reliant Bancorp and its wholly-owned bank subsidiary, the Bank, are periodically involved as a plaintiff or defendant in various legal actions in the ordinary course of business. Neither Reliant Bancorp nor the Bank is involved in any litigation that is expected to have a material impact on our financial position or results of operations. Management believes that any claims pending against Reliant Bancorp or its subsidiaries are without merit or that the ultimate liability, if any, resulting from them will not materially affect the Bank’s financial condition or Reliant Bancorp’s consolidated financial position.

Item 1A. Risk Factors.

There are no material changes from the risk factors set forth under Part I, Item 1A. "Risk Factors" in Reliant Bancorp's Annual Report on Form 10-K for the year ended December 31, 2019 and under Part II, Item 1A. "Risk Factors" in Reliant Bancorp's Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, except as described below.

The COVID-19 pandemic has had and is likely to continue to have an adverse effect, which could be material, on our business, results of operations, and financial condition.

The COVID-19 pandemic has resulted in widespread economic and financial disruptions that have adversely affected, and are likely to continue to adversely affect, our customers and other businesses in our market area. The extent of the effect on our customers and market area, and the resulting impact on our business, financial condition, liquidity and results of operations, are unknown at this time, and will depend on a number of factors beyond our control, including without limitation:

•the duration and ultimate severity of the COVID-19 pandemic, and the timing of development and widespread availability of effective medical treatments or vaccines;

•the continued response of governmental authorities, which previously have significantly curtailed business and individual activities;

•the success of monetary, fiscal, and other economic policies and programs adopted or implemented by governmental authorities, such as the Paycheck Protection Program, and designed to provide economic assistance to individuals and small businesses and otherwise mitigate the financial impact of the COVID-19 pandemic on businesses and individuals;

•compliance, operational or reputational risks related to our participation in governmental programs, including increased costs and the risk of litigation or regulatory action;

•continuing negative trends in unemployment and consumer confidence; and

•customer demand for our products and services.

Many of the risks described under Part I, Item 1A. "Risk Factors" in Reliant Bancorp's Annual Report on Form 10-K for the year ended December 31, 2019, will likely be exacerbated, and the impact of such risks will likely be magnified, as a result of the COVID-19 pandemic. The following discussion highlights some areas where the negative impacts of the COVID-19 pandemic on our business, financial condition, liquidity and results of operations are expected to be most severe.

•Loan Credit Quality. Approximately 18% of our loan portfolio is comprised of non-owner-occupied loans to borrowers in the hotel, restaurant and retail industries. These industries have been more severely impacted by the COVID-19 pandemic and governmental responses, such as stay-at-home orders and social distancing requirements, than other industries, and may have a longer recovery period than other industries. Aside from the industries mentioned above, we have other borrowers whose ability to make loan payments is dependent on rental income from their tenants, some of whom are engaged in businesses significantly impacted by the COVID-19 pandemic. Deteriorating economic conditions are likely to result in an increase in tenants failing to make rental payments, and economic relief programs adopted in response to the COVID-19 pandemic may permit tenants to defer or reduce rent payments. As a result of actual or expected credit losses, we may downgrade loans, increase our allowance for credit losses as a result of increases in non-performing assets,

and write-down or charge-off credit relationships, any of which will negatively impact our results of operations. We have also offered payment deferrals to many of our customers, and may need to offer further concessions or modifications, which could negatively impact our credit quality. In addition, market upheavals are likely to affect the value of real estate and commercial assets. In the event of foreclosure, we may be unable to sell the foreclosed assets at a price that will allow us to recoup all or a significant portion of the delinquent loan.

•Increased Demands on Capital and Liquidity. We have begun to experience an increased volume of loan originations, particularly SBA loans pursuant to the Paycheck Protection Program created by recent legislation. Certain of these SBA loans have mandated interest rates that are lower than our usual rates and may not be purchased by the SBA or other third parties within expected timeframes. In addition, during times of economic distress, borrowers may draw on existing lines of credit or seek additional loans to finance their businesses. These factors may result in reduced levels of capital and liquidity being available to originate more profitable loans, which could negatively impact our ability to serve our existing customers and our ability to attract new customers.

•Deposits. As a result of the COVID-19 pandemic, deposit customers are expected to retain higher levels of cash. While increased low-interest deposits could have a positive impact in the short-term, we would not expect these funds to be replenished as customers use deposit funds for liquidity for their business and individual needs. If deposit levels decline, our available liquidity would decline, and we could be forced to obtain liquidity from other sources on terms less favorable than current deposit terms, which would in turn compress margins and negatively impact our results of operations.

•Changes to Operations. We have implemented a number of operational changes in response to the COVID-19 pandemic, including work-from-home arrangements, which may result in a loss of employee engagement and productivity which could impact financial results and the operations of the Bank as well as increase risks related to cyber security

•Growth Strategy. The COVID-19 pandemic has impacted, and may for some time continue to impact, our ability to execute on our growth strategy. The continuation or worsening of the COVID-19 pandemic may limit our ability to grow organically and/or via mergers or acquisitions. Since the COVID-19 pandemic began in the United States, the level of financial institution merger and acquisition activity has significantly declined, and we cannot predict when or if such activity will rebound.

Even following medical resolution of the COVID-19 pandemic and the loosening of restrictions on business and individual activities, the U.S. and local economies may not recover quickly and may experience a prolonged recession. Our business and operations would be adversely affected, possibly materially, by a slow economic recovery or a prolonged recession.

We are subject to regulatory risks as a result of the Company’s participation in the Paycheck Protection Program.

Because of the short timeframe between the passing of the CARES Act and implementation of the PPP, some of the rules and other guidance relating to the PPP were issued after lenders began processing PPP loan applications. Also, there has been and there continues to be uncertainty in the laws, rules, and other guidance relating to the PPP. The PPP has attracted, and may continue to attract, interest from federal and state governmental and regulatory authorities and public interest groups. Although we believe our participation in the PPP has been in accordance with applicable laws, rules, and other guidance, we may in the future be subject to scrutiny and adverse actions by federal or state governmental or regulatory authorities (or other third parties) as relates to our participation in the PPP. Federal and state regulators can impose, or request that we consent to, substantial sanctions, restrictions, or other requirements if they determine there have been violations of laws, rules, or regulations or weaknesses or failures with respect to general standards of safety and soundness, any of which could adversely affect our business, reputation, results of operations, and financial condition.

The spread of COVID-19, or governmental responses to the same, may disrupt banking and other financial activity in the areas in which we operate and could potentially create business continuity issues for us.

The outbreak and spread of COVID-19 and federal, state, and local governmental responses to the same may result in disruption in the services we provide. We rely on our third-party vendors to conduct business and to process, record, and monitor transactions. If any of these vendors are unable to continue to provide us with needed services or experience interruptions in their ability to provide us with needed services, it could negatively impact our ability to serve our customers. Further, the COVID-19 pandemic could negatively impact the ability of our employees and customers to engage in banking and

other financial transactions in the geographic areas in which we operate and could create widespread issues for us. We also could be adversely affected if key personnel or a significant number of employees were to become unavailable due to infection, quarantine, or other effects of or restrictions relating to COVID-19 outbreaks in our market areas. Although we have business continuity plans and other safeguards in place, there is no assurance that such plans and safeguards will be effective.

Unpredictable future developments related to or resulting from the COVID-19 pandemic could materially and adversely affect our business and results of operations.

Because there have been no comparable recent global pandemics that resulted in similar global impact, we do not yet know the full extent of the COVID-19 pandemic’s effects on our business or operations or the global economy as a whole. Any future developments will be highly uncertain and cannot be predicted, including the scope and duration of the pandemic, the effectiveness of our work-from-home arrangements, third party providers’ ability to support our operations, and any actions taken by governmental authorities and other third parties in response to the pandemic. We are continuing to monitor the COVID-19 pandemic and related risks, although the rapid development and fluidity of the situation precludes any specific prediction as to its ultimate impact on us. However, if the COVID-19 outbreak continues to spread or otherwise results in a continuation or worsening of the current economic and commercial environments, our business, financial condition, and results of operations, as well as our regulatory capital and liquidity ratios, could be materially and adversely affected.

(2)On March 10, 2020, Reliant Bancorp's board of directors authorized a stock repurchase plan allowing Reliant Bancorp to repurchase up to $15 million of outstanding Reliant Bancorp common stock (the "Repurchase Plan"). As of June 30, 2020, Reliant Bancorp had not repurchased any shares of Reliant Bancorp common stock under the Repurchase Plan. The Repurchase Plan does not obligate Reliant Bancorp to repurchase any dollar amount or number of shares. The Repurchase Plan may be extended, modified, amended, suspended, or discontinued at any time. On April 27, 2020, we announced that our board of directors suspended the Repurchase Plan to preserve our financial strength during this challenging economic environment.

(b)  If any person(s) other than the Board call a special meeting, the request for the meeting shall: (i) be in writing, (ii) specify the general nature of the business proposed to be transacted, and (iii) be delivered to the Secretary of the Company. Upon receipt of such a request, the Board shall determine the date, time, and place of such special meeting, which must be scheduled to be held on a date that is within 90 days of receipt by the Secretary of the request therefor, unless a later date is required in order to allow the Company to file any information required under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Secretary of the Company shall prepare a notice of a special meeting properly requested hereunder. No business may be transacted at such special meeting other than the business specified in the notice to shareholders of such meeting.

        

(c) In the case of a special meeting requested pursuant to Section 3.2(b), the Chairman shall have the power and duty (i) to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in Section 3.2 and Section 3.9, and (ii) if any proposed nomination or business was not made or proposed in compliance with these bylaws or the stated business to be brought before the special meeting is not a proper subject for shareholder action under applicable law, to declare that such nomination shall be disregarded or that such proposed business shall not be transacted.

        

(d) A special meeting requested pursuant to Section 3.2(b) shall not be held if (i) the Board calls for an annual meeting of shareholders to be held within 90 days of receipt by the Secretary of the request for the special meeting and the Board determines in good faith that the business of such annual meeting includes (among any other matters properly brought before the annual meeting) the business specified in such special meeting request; (ii) an annual or special meeting was held within 90 days before receipt by the Secretary of the request for the special meeting and the Board determines in good faith that the business of such prior annual or special meeting included (among any other matters properly brought before such prior annual or special meeting) the business specified in such special meeting request; or (iii) the Board determines in good faith that all of the stated business to be brought before such special meeting is not a proper subject for shareholder action under applicable law.

         

Section 3.3. Notice of Meetings of Shareholders.

(a)Written notice of the date, time, and place of each annual or special meeting of the shareholders of the Company shall be given to all shareholders entitled to notice of the meeting, at the addresses shown on the stock records of the Company for such persons, no fewer than 10 days nor more than 60 days prior to the date of the meeting. Notice of any special meeting of the shareholders of the Company shall state the purpose or purposes of the meeting.

Section 3.4. Quorum and Voting Requirements. The holders of a majority of the shares entitled to vote on a matter to be considered at an annual or special meeting of the shareholders, present in person or by proxy, shall constitute a quorum at any meeting of the shareholders of the Company with respect to

that matter. However, if such a majority shall not be present, in person or by proxy, at any meeting of Company shareholders, the shareholders present, in person or by proxy, may adjourn the meeting, without notice other than the announcement at the meeting of the date, time, and place to which the meeting is adjourned. At any such adjourned meeting, any business may be transacted which might have been transacted at the meeting as originally notified. Once a share is represented for any purpose at a meeting, it shall be deemed present for quorum purposes for the remainder of the meeting and any adjournment thereof unless a new record date is or must be set for the adjourned meeting. If a quorum exists, action on a matter, including the election of directors, by a voting group is approved if the votes cast within the voting group in favor of the action exceed the votes cast in opposition of the action, unless a greater number of affirmative votes is required by the charter of the Company, these bylaws, or the Tennessee Business Corporation Act.

Section 3.5. Administration of the Meeting.

(a)  The Chairman of the Board shall preside at all meetings of the shareholders of the Company. In the event of the Chairman’s absence, incapacity, or refusal to serve, any authorized Company officer or director appointed by the Board prior to the meeting shall so preside.

(b) The Board shall be entitled to make such rules or regulations for the conduct of meetings of shareholders as it shall deem necessary, appropriate, or convenient. Subject to such rules and regulations, if any, the Chairman shall have the right and authority to prescribe such rules, regulations, and procedures and to do all acts as, in the judgment of such Chairman, are necessary, appropriate, or convenient for the proper conduct of any meeting, including without limitation establishing an agenda of business of the meeting, rules or regulations to maintain order, restrictions on entry to the meeting after the time fixed for commencement thereof, and the date and time of the opening and closing of the polls for each matter upon which the shareholders will vote at the meeting (and shall announce such at the meeting).

Section 3.6. Voting Power and Record Date. Each shareholder shall be entitled to that number of votes for each share of capital stock of the Company held by such shareholder as set forth in the charter of the Company or provided by law. For purposes of determining shareholders entitled to notice of or to vote at any meeting of Company shareholders, or any adjournment thereof, or shareholders entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other proper purpose, the Board shall fix in advance a date (the “Record Date”) as the record date for any such determination of shareholders, which Record Date shall be not more than 60 days, and with respect to any meeting of Company shareholders not fewer than 10 days, prior to the date on which the particular meeting or other action requiring such determination of shareholders is to be held or taken. Except as otherwise provided in the Tennessee Business Corporation Act, when a determination of shareholders entitled to notice of or to vote at any meeting of Company shareholders has been made, such determination shall be effective for any adjournment of such meeting.

Section 3.7. Proxies. Each shareholder eligible to vote at a meeting of shareholders shall be entitled to vote by proxy, and proxies shall be provided with the notice of any meeting of shareholders. Proxies must be signed by the owner(s) of the shares to be voted on the proxies provided and shall be valid for only one meeting, to be specified on the proxy form, and any adjournment(s) of such meeting. An appointment of a proxy is effective when received by the Secretary of the Company or any other officer or agent authorized to tabulate votes. All proxies shall be dated and filed with the records of the meeting of Company shareholders to which they relate.

        Section 3.8. Notice of Shareholder Proposals.

(a)At any special or annual meeting of shareholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting, business must be (i) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board; (ii) otherwise properly brought before the meeting by or at the direction of the Board; or (iii) otherwise properly brought before the meeting by a shareholder.

(b)In order for business to be properly brought before an annual meeting by a shareholder, the shareholder must, in addition to any other applicable requirement, have given timely notice in proper form to the Secretary of the Company. To be timely, a shareholder’s notice must be delivered to or mailed and received at the principal office of the Company (i) not later than the close of business on the 90th day nor earlier than the close of business on the 120th calendar day in advance of the anniversary of the previous year’s annual meeting if such meeting is to be held on a date that is not more than 30 days in advance of the anniversary of the previous year’s annual meeting or not later than 70 days after the anniversary of the previous year’s annual meeting, and (ii) with respect to any other annual meeting, the close of business on the 10th day following the date of public disclosure of the date of such meeting. In no event shall the public disclosure of an adjournment or postponement of an annual meeting commence a new notice time period (or extend any notice time period). To be in proper form, a shareholder’s notice to the Secretary shall be in writing and set forth (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting; (ii) the name and address, as they appear on the Company’s books, of the shareholder proposing such business; (iii) the class and number of shares of capital stock of the Company beneficially owned by the shareholder; (iv) any material interest of the shareholder in such business; and (v) any other information that is required to be provided by the shareholder pursuant to Rule 14A under the Exchange Act in the shareholder’s capacity as a proponent of a shareholder proposal. Notwithstanding the foregoing, in order to include information with respect to a shareholder proposal in the proxy statement and form of proxy for a meeting of shareholders, shareholders must provide notice as required by the regulations promulgated under the Exchange Act and meet the eligibility and other requirements set out in Rule 14. Notwithstanding anything in these bylaws to the contrary, no business shall be conducted at any annual meeting except in accordance with the procedures set forth in this section and the Exchange Act and the rules promulgated thereunder. In the event of a discrepancy between these bylaws and the rules promulgated under the Exchange Act, the rules shall govern.

(c)The Chairman of the meeting shall, if the facts warrant, determine and declare at the meeting that business was not properly brought before the meeting in accordance with this section, and if the Chairman should so determine, the Chairman shall so declare at the meeting that any such business not properly brought before the meeting shall not be transacted.

(d)In order for business to be properly brought by a shareholder before a requested special meeting, a shareholder must comply with the procedures set forth in Section 3.2 of these bylaws.

        Section 3.9. Advance Notice of Director Nominations.

(a) Only persons who are nominated in accordance with the procedures set forth in this section shall be eligible for election as directors of the Company. To be properly brought before an annual meeting of shareholders, or any special meeting of shareholders called for the purpose of electing directors, nominations for the election of directors must be (i) specified in the notice of meeting (or any supplement thereto), (ii) made by or at the direction of the Board (or any duly authorized committee

5

---

thereof), or (iii) made by a shareholder of the Company (A) who is a shareholder of record on the date of the giving of the notice provided for in this Section 3.9 and on the record date for the determination of shareholders entitled to vote at such meeting and (B) who complies with the notice procedures set forth in this Section 3.9.

(b) In addition to any other applicable requirements, for a nomination to be made by a shareholder, such shareholder must have given timely notice thereof in proper written form to the Secretary of the Company. To be timely, a shareholder’s notice to the Secretary must be received at the principal executive offices of the Company, in the case of an annual meeting, in accordance with the provisions set forth in Section 3.8, or, in the case of a special meeting of shareholders called for the purpose of electing directors, not later than the close of business on the 10th day following the day on which notice of the date of the special meeting was mailed or public disclosure of the date of the special meeting was made, whichever first occurs.

(c)  To be in proper written form, a shareholder’s notice to the Secretary must set forth:

(i)  as to each person whom the shareholder proposes to nominate for election as a director, (A) the name, age, business address and residence address of the person, (B) the principal occupation or employment of the person, (C) the class or series and number of shares of capital stock of the Company owned beneficially or of record by the person, (D) a description of all arrangements or understandings between the shareholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nominations are to be made by the shareholder, and (E) any other information relating to such person that is required to be disclosed in solicitations of proxies for elections of directors, or is otherwise required, in each case pursuant to Rule 14A under the Exchange Act (including without limitation such person’s written consent to being named in the proxy statement, if any, as a nominee and to serving as a director if elected); and

(ii)  as to such shareholder giving notice, the information required to be provided pursuant to Section 3.8.

(d) No person shall be eligible for election as a director of the Company unless nominated in accordance with the procedures set forth in this Section 3.9. If the Chairman properly determines that a nomination was not made in accordance with the foregoing procedures, the Chairman shall declare to the meeting that the nomination was defective and such defective nomination shall be disregarded.

ARTICLE IV

BOARD OF DIRECTORS

Section 4.1. Board Powers and Composition.

(a) The business and affairs of the Company shall be managed under the direction of the Board, which shall meet not less than annually. In addition to the powers and authority conferred upon the Board by these bylaws, the Board may exercise all such powers and do such acts and things as it may be authorized or required to do by statute, by rule or regulation of applicable regulatory authorities, or by the charter or the shareholders of the Company.

(b) The Board shall consist of at least five but no more than 25 individuals. The number of members of the Board may from time to time be fixed or changed, within the range set forth above, by resolution of the Board. Directors shall be elected annually at the annual meeting of the shareholders of

6

---

the Company. Prior to the 2019 annual meeting of Company shareholders, directors shall be elected by a plurality of the votes cast by those shares entitled to vote for the election of directors, assuming the presence of a quorum at the meeting. Commencing at the 2019 annual meeting of Company shareholders, and thereafter, directors shall be elected by a majority of the votes cast by those shares entitled to vote for the election of directors, assuming the presence of a quorum at the meeting, unless the number of nominees for director exceeds the number of directors to be elected, in which case directors shall instead be elected by a plurality of the votes cast by those shares entitled to vote in the election assuming the presence of a quorum at the meeting.

All action taken by a committee of the Board shall be subject to review and rejection, revision, or alteration by the Board; provided that the rejection, revision, or alteration by the Board of any action properly taken by a committee of the Board shall not affect the rights of persons who have in good faith relied upon such action.

ARTICLE VI

INDEMNIFICATION

Section 6.1. Parties to Proceedings. Each person who was or is made a party to, or is threatened to be made a party to or is otherwise involved in, any action, suit, or proceeding, whether civil, criminal, administrative, or investigative (hereinafter a “Proceeding”), by reason of the fact that he or she is or was a director or officer of the Company or is or was serving at the request of the Company as a director, officer, or employee of another corporation or of a partnership, joint venture, trust, or other enterprise, including service with respect to employee benefit plans (hereinafter an “Indemnitee”), provided that the basis of such Proceeding is alleged action in an official capacity as a director, officer, or employee within the scope of such Indemnitee’s duties and authority, shall be indemnified and held harmless by the Company to the fullest extent authorized by the Tennessee Business Corporation Act, as the same now exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than such law permitted the Company prior to such amendment), and applicable federal laws and regulations (including without limitation applicable Federal Deposit Insurance Corporation regulations regarding indemnification payments by a depository institution holding company, as the same may be amended from time to time), against all expense, liability, and loss (including without limitation attorneys’ fees, judgments, fines, excise taxes, penalties, and amounts paid into settlement) reasonably incurred or suffered by such Indemnitee in connection therewith, and such indemnification shall continue as to an Indemnitee who has ceased to be a director, officer, or employee and shall inure to the benefit of the Indemnitee’s heirs, executors, and administrators; provided, however, that, except as provided in Section 6.2 of these bylaws with respect to Proceedings to enforce rights to indemnification, the Company shall indemnify only if such Proceeding (or part thereof) was authorized by the Board. The right to indemnification conferred in this Article VI shall be a contract right and shall include the right to be paid by the Company the expenses incurred in defending any such Proceeding in advance of its final disposition (hereinafter an “Advancement of Expenses”); provided, however, that an Advancement of Expenses for expenses incurred by an Indemnitee in his or her capacity as a director, officer, or employee (and not in any other capacity in which service was or is rendered by such Indemnitee, including without limitation service to any employee benefit plan) shall be made only upon delivery to the Company of an undertaking by and on behalf of such Indemnitee to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right of appeal that such Indemnitee is not entitled to be indemnified for such expenses under this Article VI or otherwise (hereinafter an “Undertaking”).

Section 6.2. Claims. If a claim under Section 6.1 of these bylaws is not paid in full by the Company within 30 days after receipt by the Company of written notice of such claim, except in the case of a claim for an Advancement of Expenses in which case the applicable period shall be 10 days, the Indemnitee may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, the Indemnitee also shall be entitled to be paid the expenses of prosecuting or defending such suit. In (a) any suit brought by an Indemnitee to enforce a right of indemnification hereunder (but not in a suit brought by an Indemnitee to enforce a right to an Advancement of Expenses) and (b) any suit brought by the Company to recover an Advancement of Expenses upon a final adjudication, it shall be a defense that the Indemnitee has not met the applicable standard of conduct set forth in the Tennessee Business Corporation Act or applicable federal laws or regulations. Neither the failure of the Company (including the Board, independent legal counsel, or the Company’s shareholders) to have made a determination prior to the commencement of such suit that indemnification of the Indemnitee is proper in the circumstances or that the Indemnitee has met the applicable standard of conduct set forth in the Tennessee Business Corporation Act or applicable federal

11

---

laws or regulations nor an actual determination by the Company (including the Board, independent legal counsel, or the Company’s shareholders) that the Indemnitee has not met such applicable standard of conduct shall create a presumption that the Indemnitee has not met such applicable standard of conduct or, in the case of any such suit brought by the Indemnitee, be a defense to such suit. In any suit brought by an Indemnitee to enforce a right hereunder or by the Company to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified or to such Advancement of Expenses under this Article VI or otherwise shall be on the Company.

Section 6.3. Non-Exclusivity of Rights. The rights to indemnification and to the advancement of expenses conferred in this Article VI shall not be exclusive of any other right which any person may have or hereafter acquire under or by these bylaws or any statute, agreement, or vote of shareholders or disinterested directors, or otherwise.

Section 6.4. Other Indemnification. The Company may, to the extent authorized from time to time by the Board, grant all or any of the rights to indemnification and/or to the advancement of expenses afforded directors, officers, and employees of the Company in this Article VI to any agent of the Company.

Section 6.5. Insurance. The Company may, but shall not be obligated to, maintain insurance, at its own expense, to protect itself and any person who is or was a director, officer, employee, or agent of the Company, or who while a director, officer, employee, or agent of the Company is or was serving at the request of the Board as a director, officer, partner, trustee, employee, or agent of another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, against any expense, liability, or loss, whether or not the Company would have the power to indemnify such person against such expense, liability, or loss under this Article VI, the Tennessee Business Corporation Act, or applicable federal laws and regulations.

The enumeration in this Section 9.1 of particular powers or authority shall not restrict in any way the general powers and authority of the Chairman of the Board, the President, and the Chief Executive Officer. The Board may authorize any other officer(s) or agent(s) of the Company to enter into any contract or execute and deliver any other document or instrument in the name of and on behalf of the Company, and such authority may be general or confined to specific instances.

Section 9.2. Receipts, Checks, Drafts, Etc.

The President, the Chief Executive Officer, and any other officer or employee of the Company designated by the Board shall be authorized and empowered to, on behalf of the Company and in its name, endorse checks and warrants, to draw drafts, and to give receipts for money due and payable to the Company.

Section 9.3. Loans. No loan shall be contracted on behalf or in the name of the Company, and no negotiable paper shall be issued in its name, unless the same shall have been authorized by the Board, which authority may be general or limited to specific instances.

(a)  Without limiting the manner by which notice otherwise may be given effectively to shareholders pursuant to the Tennessee Business Corporation Act, the charter of the Company, or these bylaws, any notice to shareholders given by the Company shall be effective if given by a form of electronic transmission consented to by the shareholder to whom the notice is given. Any such consent shall be revocable by the shareholder by written notice to the Company. Any such consent shall be deemed revoked if (i) the Company is unable to deliver by electronic transmission two consecutive notices given by the Company in accordance with such consent; and (ii) such inability becomes known to the Secretary of the Company or to the transfer agent, or other person responsible for the giving of notice; provided, however, that the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action.

For purposes of these bylaws, the term “electronic transmission” means any form of communication, not directly involving the physical transmission of paper, that creates a record that may be retained, retrieved, and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such a recipient through an automated process.

Summary of Significant Accounting Policies	6 Months Ended
	Jun. 30, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accounting and reporting policies of Reliant Bancorp, Inc. conform to accounting principles generally accepted in the United States of America ("U.S. GAAP") and to general practices within the banking industry. The following is a brief summary of the significant policies. Nature of Operations Reliant Bancorp, Inc. is a Tennessee corporation and the holding company for and the sole shareholder of Reliant Bank. Reliant Bancorp is registered as a financial holding company under the Bank Holding Company Act of 1956, as amended ("Bank Holding Company Act"). Reliant Bank is a commercial bank chartered under Tennessee law and a member of the Federal Reserve System (the "Federal Reserve"). Reliant Bank, Reliant Bancorp's wholly-owned bank subsidiary, provides a full range of traditional banking products and services to business and consumer clients throughout Middle Tennessee and the Nashville-Davidson-Murfreesboro-Franklin, TN Metropolitan Statistical Area (the “Nashville MSA”) and Chattanooga, Tennessee. Reliant Bank operates banking centers in Cheatham, Davidson, Hamilton, Hickman, Maury, Montgomery, Robertson, Rutherford, Sumner, and Williamson counties, Tennessee. Additionally, Reliant Bank operates mortgage offices in Brentwood, Chattanooga, Hendersonville, and Memphis, Tennessee, as well as two in Little Rock and one in Crossett, Arkansas. On January 1, 2020, TCB Holdings, a community banking organization headquartered in Ashland City, Tennessee, was merged with and into Reliant Bancorp. On April 1, 2020, First Advantage Bancorp, a community banking organization headquartered in Clarksville, Tennessee, was merged with and into Reliant Bancorp (See Note 12). Reliant Risk Management, Inc., a newly-formed, wholly-owned insurance captive subsidiary of Reliant Bancorp, Inc. that began operations on June 1, 2020, is a Tennessee-based captive insurance company which insures Reliant Bancorp and the Bank against certain risks unique to their operations and for which insurance may not be currently available or economically feasible in today's insurance marketplace. Reliant Risk Management, Inc. pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. Reliant Risk Management, Inc. is subject to regulations of the State of Tennessee and undergoes periodic examinations by the Tennessee Department of Commerce and Insurance. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Quarterly Report on Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with U.S. GAAP.  All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods covered by the report have been included.  The accompanying unaudited consolidated financial statements should be read in conjunction with Reliant Bancorp, Inc.’s consolidated financial statements and related notes appearing in Reliant Bancorp, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2019. The consolidated financial statements as of and for the periods presented include the accounts of Reliant Bancorp, Inc., Reliant Bank (the "Bank"), Community First Trups Holding Company ("TRUPS"), which is wholly owned by Reliant Bancorp, Inc., Reliant Risk Management, Inc. ("Risk"), which is wholly owned by Reliant Bancorp Inc., Reliant Investment Holdings, LLC ("Holdings"), which is wholly owned by the Bank, and Reliant Mortgage Ventures, LLC ("RMV"), of which the Bank controls 51% of the governance rights. Reliant Bancorp Inc., the Bank, TRUPS, Risk, Holdings, and RMV are collectively referred to herein as the “Company”. All significant inter-company balances and transactions have been eliminated in consolidation. As described in Note 12 to these unaudited consolidated financial statements, Reliant Bancorp, Inc. and TCB Holdings merged effective on January 1, 2020, and Reliant Bancorp, Inc. and FABK merged effective April 1, 2020. The accounting and reporting policies of the Company conform to U.S. GAAP and general practices in the banking industry. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to determination of the allowance for loan losses, the valuation of other real estate, the valuation of debt and equity securities, the valuation of deferred tax assets and fair values of financial instruments. The consolidated financial statements as of June 30, 2020, and for the three and six months ended June 30, 2020 and 2019, included herein have not been audited. The accounting and reporting policies of the Company conform to U.S. GAAP and Article 8 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although the Company believes that the disclosures made are adequate to make the information not misleading. The accompanying consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary to present a fair statement of the results for the interim periods presented. Such adjustments are of a normal recurring nature. The Company evaluates subsequent events through the date of filing. Certain prior period amounts have been reclassified to conform to the current period presentation. The results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. Recently Adopted Accounting Pronouncements Information about certain issued accounting standards updates is presented below. Also refer to Note 1 - Summary of Significant Accounting Policies, “Recent Authoritative Accounting Guidance” in the Annual Report on Form 10-K for the year ended December 31, 2019 for additional information related to previously issued accounting standards updates. ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 went into effect for the Company on January 1, 2020 and the Company elected the prospective application approach provided by ASU 2018-11 and did not adjust prior periods for ASC 842. The Company also elected certain practical expedients within the standard and consistent with such elections did not reassess whether any expired or existing contracts are or contain leases, did not reassess the lease classification for any expired or existing leases, and did not reassess any initial direct costs for existing leases. The effect of implementing this pronouncement resulted in right to use assets of $11,973 and a similar corresponding liability, as of January 1, 2020.

In March 2020, the FASB issued Topic 848 amendments to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. It provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company has evaluated the effect of the pronouncement on the consolidated financial statements, noting no significant impact. Newly Issued not yet Effective Accounting Standards ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available for sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 is expected to be effective on January 1, 2023. We are currently evaluating the potential impact of ASU 2016-13 on the Company's financial statements. We are currently developing an implementation plan to include assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs, among other things. The adoption of ASU 2016-13 could result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, ASU 2016-13 will necessitate that we establish an allowance for expected credit losses for certain debt securities and other financial assets. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Financial Instruments - Credit Losses (ASC 326), Derivatives and Hedging (ASC 815), and Financial Instruments (ASC 825). The amendments in this ASU improve the codification by eliminating inconsistencies and providing clarifications. The amended guidance in this ASU related to credit losses will be effective for the Company for fiscal years and interim periods beginning after December 15, 2022. The Company is currently evaluating the impact of these ASUs on the Company’s consolidated financial statements. While we are currently unable to reasonably estimate the impact of adopting these ASUs, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of the Company's loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date. ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for the Company on January 1, 2021, with earlier adoption permitted and is not currently expected to have a significant impact on the Company's consolidated financial statements as it simplifies the test of impairment of goodwill.

Collection risk in this portfolio is driven by the creditworthiness of underlying borrowers, particularly cash flow from customers’ business operations. Commercial, industrial and agricultural loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial and industrial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. Multi-family and commercial real estate: Multi-family and commercial real estate loans are subject to underwriting standards and processes similar to commercial, industrial and agricultural loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties comprising the Company’s commercial real estate portfolio are diverse in terms of type. This diversity helps reduce the Company’s exposure to adverse economic events that affect any single market or industry. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. The Company also utilizes third-party experts to provide insight and guidance about economic conditions and trends affecting the market areas it serves. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans. Non-owner occupied commercial real estate loans are loans secured by multifamily and commercial properties where the primary source of repayment is derived from rental income associated with the property (that is, loans for which 50 percent or more of the source of repayment comes from third party, nonaffiliated, rental income) or the proceeds of the sale, refinancing, or permanent financing of the property. These loans are made to finance income-producing properties such as apartment buildings, office and industrial buildings, and retail properties. Owner-occupied commercial real estate loans are loans where the primary source of repayment is the cash flow from the ongoing operations and business activities conducted by the party, or an affiliate of the party, who owns the property. Construction and land development: Loans for non-owner-occupied real estate construction or land development are generally repaid through cash flow related to the operation, sale or refinance of the property. The Company also finances construction loans for owner-occupied properties. A portion of the Company’s construction and land development portfolio segment is comprised of loans secured by residential product types (residential land and single-family construction). With respect to construction loans to developers and builders that are secured by non-owner occupied properties that the Company may originate from time to time, the Company generally requires the borrower to have had an existing relationship with the Company and have a proven record of success. Construction and land development loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates, market sales activity, and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing.          1-4 family residential real estate: Residential real estate loans, which include related manufactured homes with real estate, represent loans to consumers or investors to finance a residence. These loans are typically financed on 15- to 30-year amortization terms, but generally with shorter maturities of 5 to 15 years. Many of these loans are extended to borrowers to finance their primary or secondary residence. Loans to an investor secured by a 1-4 family residence will be repaid from either the rental income from the property or from the sale of the property. This loan segment also includes closed-end home equity loans that are secured by a first or second mortgage on the borrower’s residence. This allows customers to borrow against the equity in their home. Loans in this portfolio segment are underwritten and approved based on a number of credit quality criteria including limits on maximum Loan-to-Value ("LTV"), minimum credit scores, and maximum debt to income. Real estate market values as of the time the loan is made directly affect the amount of credit extended and, in addition, changes in these market values impact the depth of potential losses in this portfolio segment. 1-4 family HELOC: This loan segment includes open-end home equity loans that are secured by a first or second mortgage on the borrower’s residence. This allows customers to borrow against the equity in their home utilizing a revolving line of credit. These loans are underwritten and approved based on a number of credit quality criteria including limits on maximum LTV, minimum credit scores, and maximum debt to income. Real estate market values as of the time the loan is made directly affect the amount of credit extended and, in addition, changes in these market values impact the depth of potential losses in this portfolio segment. Because of the revolving nature of these loans as well as the fact that many represent second mortgages, this portfolio segment can contain more risk than the amortizing 1-4 family residential real estate loans. Consumer: The consumer loan portfolio segment includes non-real estate secured direct loans to consumers for household, family, and other personal expenditures as well as manufactured homes without real estate. Consumer loans may be secured or unsecured and are usually structured with short or medium term maturities. These loans are underwritten and approved based on a number of consumer credit quality criteria including limits on maximum LTV on secured consumer loans, minimum credit scores, and maximum debt to income. Many traditional forms of consumer installment credit have standard monthly payments and fixed repayment schedules of one to five years. These loans are made with either fixed or variable interest rates that are based on specific indices. Loans to finance manufactured homes that are not secured by real estate are classified as consumer loans and have standard monthly payments and fixed repayment schedules of 15 to 23 years. Installment loans fill a variety of needs, such as financing the purchase of an automobile, a boat, a recreational vehicle, or other large personal items, or for consolidating debt. These loans may be unsecured or secured by an assignment of title, as in an automobile loan, or by money in a bank account. In addition to consumer installment loans, this portfolio segment also includes secured and unsecured personal lines of credit as well as overdraft protection lines. Loans in this portfolio segment are sensitive to unemployment and other key consumer economic measures. Non-accrual loans by class of loan were as follows at June 30, 2020 and December 31, 2019: June 30, 2020 December 31, 2019 Commercial, Industrial and Agricultural $ 928    $ 572    Multi-family and Commercial Real Estate 2,711    1,276    Construction, Land Development and Farmland 412    555    1-4 Family Residential Real Estate 1,468    1,344    1-4 Family HELOC 241    296    Consumer 1,781    28    Total $ 7,541    $ 4,071    Performing non-accrual loans totaled $2,392 and $1,332 at June 30, 2020 and December 31, 2019, respectively.

Loans are graded on a scale of 1 to 9. Grades 1 to 5 are pass credits, grade 6 is special mention, grade 7 is substandard, grade 8 is doubtful and grade 9 is loss. A description of the risk grades are as follows:         Grade 1 - Minimal Risk (Pass) This grade includes loans to borrowers with a strong financial position and history of profits and cash flows sufficient to service the debt. These borrowers have well defined sources of primary/secondary repayment, conservatively leveraged balance sheets and the ability to access a wide range of financing alternatives. Collateral securing these loans is negotiable, of sufficient value and in possession of the Company. Risk of loss is unlikely.         Grade 2 - High Quality (Pass) This grade includes loans to borrowers with a strong financial condition reflecting dependable net profits and cash flows. The borrower has verifiable liquid net worth providing above average asset protection. An identifiable market exists for the collateral. Risk of loss is unlikely.         Grade 3 - Above Average (Pass) This grade includes loans to borrowers with a balance sheet that reflects a comfortable degree of leverage and liquidity. Borrowers are profitable and have a sustained record of servicing debt. An identifiable market exists for the collateral, but liquidation could take up to one year. Risk of loss is unlikely.         Grade 4 - Average (Pass) This grade includes loans to borrowers with a financial condition that is satisfactory and comparable to industry standards. The borrower has verifiable net worth, providing over time average asset protection. The borrower's cash flows are sufficient to satisfy debt service requirements. Risk of loss is below average.         Grade 5 - Acceptable (Management Attention) (Pass) This grade includes loans to borrowers whose loans are performing, but sources of repayment are not documented by the current credit analysis. There are some declining trends in margins, ratios and/or cash flow. Guarantor(s) have strong net worth(s), but assets may be concentrated in real estate or other illiquid investments. Risk of loss is average.         Grade 6 - Special Mention Special mention assets have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company’s position at some future date. These assets pose elevated risk, but their weakness does not yet justify a substandard classification. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or an ill proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a special mention rating. Nonfinancial reasons for rating a credit exposure special mention include management problems, pending litigation, an ineffective loan agreement or other material structural weakness, and any other significant deviation from prudent lending practices. The special mention rating is designed to identify a specific level of risk and concern about asset quality. Although a special mention asset has a higher probability of default than a pass asset, its default is not imminent.         Grade 7 - Substandard A ‘‘substandard’’ extension of credit is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Extensions of credit so classified should have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard credits, does not have to exist in individual extensions of credit classified substandard. Substandard assets have a high probability of payment default, or they have other well-defined weaknesses. They require more intensive supervision by Company management. Substandard assets are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk mitigation.          Grade 8 - Doubtful An extension of credit classified ‘‘doubtful’’ has all the weaknesses inherent in one classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors that may work to the advantage of and strengthen the credit, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors may include a proposed merger or acquisition, liquidation proceedings, capital injection, perfecting liens on additional collateral, or refinancing plans. Generally, the doubtful classification should not extend for a long period of time because in most cases the pending factors or events that warranted the doubtful classification should be resolved either positively or negatively in a reasonable period of time.         Grade 9 - Loss Extensions of credit classified ‘‘loss’’ are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the credit has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. Amounts classified loss should be promptly charged off. The Company will not attempt long term recoveries while the credit remains on the Company’s books. Losses should be taken in the period in which they surface as uncollectible. With loss assets, the underlying borrowers are often in bankruptcy, have formally suspended debt repayments, or have otherwise ceased normal business operations. Once an asset is classified loss, there is little prospect of collecting either its principal or interest. Non-commercial purpose loans are initially assigned a default loan grade of 99 (Pass) and are risk graded (Grade 6, 7, or 8) according to delinquency status when applicable.

The Company had applied this guidance to approve initial modifications in April and May 2020 for loans with principal balances of $530.7 million. The majority of these modifications were for a period of up to three months and contained either interest-only periods or full payment deferrals. Through August 5, 2020, further modifications were approved for $39.0 million of the loans previously modified. Additional modifications of these loans are likely to be executed in the third quarter of 2020. The CARES Act provides over $2.0 trillion in emergency economic relief to individuals and businesses impacted by the COVID-19 pandemic. The CARES Act authorized the Small Business Administration (“SBA”) to administer new loan programs including, but not limited to, the guarantee of loans under a new 7(a) loan program called the Paycheck Protection Program (“PPP”). Upon completion of the FABK Transaction as disclosed in Note 12, we assumed their qualified SBA lender status. The Company originated $83.3 million of PPP loans in the second quarter of 2020 which are included in the commercial, industrial, and agricultural segment.

Other Real Estate [Abstract]
OTHER REAL ESTATE	OTHER REAL ESTATEAt June 30, 2020, and December 31, 2019, the Company held other real estate recorded at a value of $2,514 and $750, respectively, which represents fair value less costs to sell. The June 30, 2020 balance included retired bank facilities of $2,420 and two manufactured housing properties valued at $94. These residential properties were part of the four properties valued at $208 added through the acquisition of First Advantage Bank in the second quarter of 2020. During the three months ended June 30, 2020, the Company sold two of these properties resulting in a gain on sale of $11. Additionally, at June 30, 2020, there were three real estate loans with related balances totaling $320 in the process of foreclosure. Of the two retired bank facilities no longer in use, one sold as of July 31, 2020. Expenses related to other real estate totaled $4 for the three and six months ended June 30, 2020, respectively.

Fair Values of Assets and Liabilities	6 Months Ended
	Jun. 30, 2020
Fair Value Disclosures [Abstract]
FAIR VALUES OF ASSETS AND LIABILITIES	FAIR VALUES OF ASSETS AND LIABILITIES   Financial accounting standards relating to fair value measurements establish a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access. Level 2 Inputs to the valuation methodology include: •Quoted prices for similar assets or liabilities in active markets; •Quoted prices for identical or similar assets or liabilities in inactive markets; •Inputs other than quoted prices that are observable for the asset or liability; and •Inputs that are derived principally from or corroborated by the observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability. Level 3 Inputs to the valuation methodology are unobservable and reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques should maximize the use of observable inputs and minimize the use of unobservable inputs. Following is a description of the valuation methodologies used for assets and liabilities measured at fair value on a recurring basis: Securities available for sale: The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The Company obtains fair value measurements for securities available for sale from an independent pricing service. The fair value measurements consider observable data that may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, cash flows and reference data, including market research publications, among other things.         Interest rate swaps: The fair values of interest rate swaps are determined based on discounted future cash flows. Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Assets and liabilities measured at fair value on a nonrecurring basis include the following: Impaired Loans: The fair value of an impaired loan with specific allocations of the allowance for loan losses is generally based on the present value of expected payments using the loan’s effective rate as the discount rate or recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Other Real Estate: The fair value of other real estate is generally based on recent real estate appraisals less estimated disposition cost. These appraisals may use a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in Level 3 classification of the inputs for determining fair value. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company’s valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates. The following table sets forth the Company’s major categories of assets and liabilities measured at fair value on a recurring basis, by level within the fair value hierarchy, as of June 30, 2020 and December 31, 2019: Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) June 30, 2020 Assets U.

Estimated cash flows change and appraised values of the assets or collateral underlying the loans will be sensitive to changes. Carrying amounts and estimated fair values of financial instruments not reported at fair value at June 30, 2020 and December 31, 2019 were as follows: June 30, 2020 Carrying Amount Estimated Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Financial assets Cash and due from banks $ 93,838    $ 93,838    $ 93,838    $ —    $ —    Federal funds sold 638    638    —    638    —    Loans, net 2,299,087    2,297,086    —    —    2,297,086    Mortgage loans held for sale 101,579    102,531    —    102,531    —    Accrued interest receivable 13,901    13,901    —    13,901    —    Restricted equity securities 17,509    17,509    —    17,509    —    Financial liabilities Deposits $ 2,530,062    $ 2,537,890    $ —    $ —    $ 2,537,890    Accrued interest payable 2,918    2,918    —    2,918    —    Subordinate debentures 70,413    67,543    —    —    67,543    Federal Home Loan Bank advances 49,121    49,552    —    —    49,552    December 31, 2019 Financial assets Cash and due from banks $ 50,990    $ 50,990    $ 50,990    $ —    $ —    Federal funds sold 52    52    —    52    —    Loans, net 1,397,374    1,383,719    —    —    1,383,719    Mortgage loans held for sale 37,476    38,379    —    38,379    —    Accrued interest receivable 7,111    7,111    —    7,111    —    Restricted equity securities 11,279    11,279    —    11,279    —    Financial liabilities Deposits $ 1,583,789    $ 1,582,117    $ —    $ —    $ 1,582,117    Accrued interest payable 2,022    2,022    —    2,022    —    Subordinate debentures 70,883    71,454    —    —    71,454    Federal Home Loan Bank advances 10,737    10,755    —    —    10,755    The methods and assumptions used to estimate fair value are described as follows: Carrying amount is the estimated fair value for cash and cash equivalents, accrued interest receivable and payable,  restricted equity securities, federal funds sold or purchased, demand deposits, and variable rate loans or deposits that re-price frequently and fully. For fixed rate loans or deposits and for variable rate loans or deposits with infrequent re-pricing or re-pricing limits, fair value is based on discounted cash flows using current market rates applied to the estimated life and credit risk. Fair value of debt is based on discounted cash flows using current rates for similar financing.

The Plan provided for the granting of stock options for up to 625,000 shares of Bank common stock to employees and organizers and authorized the issuance of Bank common stock upon the exercise of such options. As part of the Bank's reorganization into a holding company corporate structure in 2012, all Bank options were replaced with Commerce Union Bancshares, Inc. (now known as "Reliant Bancorp, Inc.") options with no change in terms. On March 10, 2015, the shareholders of Reliant Bancorp (then known as "Commerce Union Bancshares, Inc.") approved the Commerce Union Bancshares, Inc. Amended and Restated Stock Option Plan (the “A&R Plan”), which permits the grant of awards with respect to up to 1,250,000 shares of Reliant Bancorp common stock in the form of stock options. As part of the merger of Commerce Union Bank and Reliant Bank in 2015, all outstanding stock options of Reliant Bank were converted to stock options of Reliant Bancorp (then known as "Commerce Union Bancshares, Inc.") under the A&R Plan. Under the A&R Plan, stock option awards may be granted in the form of incentive stock options or non-statutory stock options, and are generally exercisable for up to 10 years following the date such option awards are granted. Exercise prices of incentive stock options must be equal to or greater than the fair market value of Reliant Bancorp's common stock on the grant date.          On June 18, 2015, the shareholders of Reliant Bancorp (then known as "Commerce Union Bancshares, Inc.") approved the Commerce Union Bancshares, Inc. 2015 Equity Incentive Plan, which reserves up to 900,000 shares of Reliant Bancorp common stock to be subject to awards under the plan, including awards in the form of stock options, restricted stock grants, performance-based awards, and other awards denominated or payable by reference to or based on or related to Reliant Bancorp common stock. Common Stock Options          A summary of stock option activity for the six months ended June 30, 2020 is as follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at January 1, 2020 149,293 $ 18.81    6.68 years $ 553    Granted —    $ —    Exercised (1,889) $ 11.47    Forfeited or expired (12,700) $ 21.82    Outstanding at June 30, 2020 134,704 $ 18.68    6.13 years $ 191    Exercisable at June 30, 2020 74,004 $ 15.63    4.82 years $ 163    Shares Weighted Average Grant-Date Fair Value Non-vested options at January 1, 2020 74,600    $6.08 Granted —    $— Vested (3,200)   $5.91 Forfeited (10,700)   $5.86 Non-vested options at June 30, 2020 60,700    $6.13          As of June 30, 2020, there was $267 of unrecognized future compensation expense to be recognized related to stock options.

Regulatory Capital Requirements	6 Months Ended
	Jun. 30, 2020
Banking and Thrift, Other Disclosures [Abstract]
REGULATORY CAPITAL REQUIREMENTS	REGULATORY CAPITAL REQUIREMENTS The Bank is subject to regulatory capital requirements administered by the federal and state banking agencies. As of June 30, 2020, Reliant Bancorp fell under the Federal Reserve's Small Bank Holding Company and Savings and Loan Holding Company Policy Statement (the “Small Bank Holding Company Policy Statement”), which is generally applicable to bank holding companies with consolidated assets of less than $3 billion, and was, therefore, not subject to consolidated capital requirements. However, we have chosen to provide our consolidated capital ratios below. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believes as of June 30, 2020, the Bank meets all capital adequacy requirements to which it is subject. Prompt corrective action regulations provide five bank capital classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If only adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At June 30, 2020 and December 31, 2019, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. In July 2013, the Federal Deposit Insurance Corporation (FDIC) approved final rules that substantially amended the regulatory risk-based capital rules applicable to Reliant Bancorp and the Bank. The final rules implement the regulatory capital reforms of the Basel Committee on Banking Supervision reflected in “Basel III: A Global Framework for More Resilient Banks and Banking Systems” ("Basel III") and changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act. Under these rules, the leverage and risk-based capital ratios of bank holding companies (other than bank holding companies that fall under the Small Bank Holding Company Policy Statement and are not subject to consolidated capital requirements) may not be lower than the leverage and risk-based capital ratios for insured depository institutions. The final rules implementing Basel III became effective on January 1, 2015, and include new minimum risk-based capital and leverage ratios and a new common equity tier 1 ratio. In addition, these rules refine the definition of what constitutes capital for purposes of calculating those ratios, including the definitions of Tier 1 capital and Tier 2 capital. Basel III established a “capital conservation buffer” of 2.5%. An institution is subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if capital levels fall below minimum levels plus the buffer. Capital amounts and ratios for Reliant Bancorp and the Bank (required) are presented below as of June 30, 2020 and December 31, 2019.

Segment Reporting	6 Months Ended
	Jun. 30, 2020
Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING The Company has two reportable business segments: retail banking and residential mortgage banking. Segment information is derived from the internal reporting system utilized by management. Revenues and expenses for segments reflect those which can be specifically identified and have been assigned based on internally developed allocation methods. Financial results have been presented, to the extent practicable, as if each segment operated on a stand-alone basis. Retail Banking provides deposit and lending services to consumer and business customers within our primary geographic markets. Our customers are serviced through branch locations, ATMs, online banking, and mobile banking. Residential Mortgage Banking originates traditional first lien residential mortgage loans and first lien home equity lines of credit throughout the United States. The traditional first lien residential mortgage loans are typically underwritten to government agency standards and sold to third-party secondary market mortgage investors. The home equity lines of credit are typically sold to participating banks or other investor groups and are underwritten to their standards. During the second quarter of 2019, RMV began acquiring loans from approved correspondent lenders and reselling them in the secondary market. These loans are not government agency-qualified loans and are of higher risk, such as jumbo loans or senior position home equity lines of credit. The following presents summarized results of operations for the Company’s business segments for the periods indicated: Three Months Ended June 30, 2020 Retail Banking Residential Mortgage Banking Elimination Entries Consolidated Net interest income $ 29,420    $ 536    $ —    $ 29,956    Provision for loan losses 3,000    —    —    3,000    Noninterest income 2,174    2,240    8    4,422    Noninterest expense (excluding merger expense) 16,433    3,199    —    19,632    Merger expense 2,632    —    —    2,632    Income tax expense (benefit) 1,661    (27)   —    1,634    Net income (loss) 7,868    (396)   8    7,480    Noncontrolling interest in net loss of subsidiary —    396    (8)   388    Net income attributable to common shareholders $ 7,868    $ —    $ —    $ 7,868      Three Months Ended June 30, 2019   Retail Banking Residential Mortgage Banking Elimination Entries Consolidated Net interest income $ 13,703    $ 110    $ —    $ 13,813    Provision for loan losses 200    —    —    200    Noninterest income 1,473    1,235    (10)   2,698    Noninterest expense (excluding merger expense) 10,129    2,996    —    13,125    Merger expense 1    —    —    1    Income tax expense (benefit) 607    (106)   —    501    Net income (loss) 4,239    (1,545)   (10)   2,684    Noncontrolling interest in net loss of subsidiary —    1,545    10    1,555    Net income attributable to common shareholders $ 4,239    $ —    $ —    $ 4,239    Six Months Ended June 30, 2020 Retail Banking Residential Mortgage Banking Elimination Entries Consolidated Net interest income $ 46,202    $ 869    $ —    $ 47,071    Provision for loan losses 5,900    —    —    5,900    Noninterest income 3,883    3,804    17    7,704    Noninterest expense (excluding merger expense) 28,894    6,150    —    35,044    Merger expense 6,818    —    —    6,818    Income tax expense (benefit) 820    (96)   —    724    Net income (loss) 7,653    (1,381)   17    6,289    Noncontrolling interest in net loss of subsidiary —    1,381    (17)   1,364    Net income attributable to common shareholders $ 7,653    $ —    $ —    $ 7,653    Six Months Ended June 30, 2019 Retail Banking Residential Mortgage Banking Elimination Entries Consolidated Net interest income $ 27,076    $ 198    $ —    $ 27,274    Provision for loan losses 200    —    —    200    Noninterest income 2,851    1,810    (25)   4,636    Noninterest expense (excluding merger expense) 20,574    5,295    —    25,869    Merger expense 3    —    —    3    Income tax expense (benefit) 1,087    (214)   —    873    Net income (loss) 8,063    (3,073)   (25)   4,965    Noncontrolling interest in net loss of subsidiary —    3,073    25    3,098    Net income attributable to common shareholders $ 8,063    $ —    $ —    $ 8,063

Derivatives	6 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and other terms of the individual interest rate swap agreements. Interest Rate Swaps Designated as Cash Flow Hedges Interest rate swaps with notional amounts totaling $160,000 as of June 30, 2020 were designated as cash flow hedges of certain short-term interest-bearing liabilities and subordinated debentures, which are fully effective. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swaps is recorded in other assets (liabilities) with changes in fair value recorded in other comprehensive income (loss). The amount included in accumulated other comprehensive income (loss) would be reclassified to current earnings should the hedges no longer be considered effective. The Company expects the hedges to remain fully effective during the remaining terms of the swap agreements. Summary information related to the interest rate swaps designated as cash flow hedges as of June 30, 2020, is as follows: Notional amounts $ 160,000    Weighted average pay rates 2.050  % Weighted average receive rates 1.679  % Weighted average maturity 3.60 years Unrealized losses $ 9,034    Cash Flow Hedges          The following table presents the net gains (losses) recorded in accumulated other comprehensive income and the Consolidated Statements of Income relating to the cash flow derivative instruments for the three months ended June 30, 2020: Amount of Gain (Loss) Recognized in OCI (Effective Portion) Amount of Gain (Loss) Reclassified from OCI to Interest Income Amount of Gain (Loss) Recognized in Other Noninterest Income (Ineffective Portion) June 30, 2020 Interest rate contracts $ (5,137)   $ —    $ —    The following table reflects the cash flow hedges included in the Consolidated Balance Sheets as of June 30, 2020 and December 31, 2019, respectively: June 30, 2020 December 31, 2019 Notional Amount Fair Value Notional Amount Fair Value Included in other liabilities: Interest rate swaps related to: Subordinate debentures $ 10,000    $ 819    $ 10,000    $ 439    Short-term interest bearing liabilities 150,000    8,215    100,000    1,639    Total included in other liabilities $ 160,000    $ 9,034    $ 110,000    $ 2,078    Fair Value Hedges The following table reflects the fair value hedges included in the Consolidated Statements of Income for the six months ended June 30, 2020 and 2019, respectively: Interest rate contracts Location June 30, 2020 June 30, 2019 Change in fair value on interest rate swaps hedging investments Interest income $ (1,131)   $ (1,057)   The following table reflects the fair value hedges included in the Consolidated Balance Sheets as of June 30, 2020 and December 31, 2019, respectively: June 30, 2020 December 31, 2019 Notional Amount Fair Value Notional Amount Fair Value Included in other assets: Interest rate swaps related to investments $ —    $ —    $ —    $ —    Total included in other assets $ —    $ —    $ —    $ —    Included in other liabilities: Interest rate swaps related to investments 19,605    1,761    19,605    630    Total included in other liabilities $ 19,605    $ 1,761    $ 19,605    $ 630

Effective January 1, 2020, Reliant Bancorp completed the acquisition of TCB Holdings pursuant to the Agreement and Plan of Merger, dated September 16, 2019 (the “TCB Holdings Agreement”), by and among Reliant Bancorp, TCB Holdings, and Community Bank & Trust, a Tennessee-chartered commercial bank and wholly owned subsidiary of TCB Holdings (“CBT”). On the terms and subject to the conditions set forth in the TCB Holdings Agreement, TCB Holdings merged with and into the Reliant Bancorp (the “TCB Holdings Transaction”), with Reliant Bancorp as the surviving corporation. Immediately following the TCB Holdings Transaction, CBT merged with and into the Bank, with the Bank continuing as the surviving banking corporation. Pursuant to the TCB Holdings Agreement, at the effective time of the TCB Holdings Transaction, each outstanding share of TCB Holdings common stock, par value $1.00 per share (other than certain excluded shares), was converted into and canceled in exchange for the right to receive (i) $17.13 in cash, without interest, and (ii) 0.769 shares of the Reliant Bancorp’s common stock, par value $1.00 per share (“Reliant Bancorp Common Stock”). The aggregate consideration payable by Reliant Bancorp in respect of shares of TCB Holdings common stock as consideration for the TCB Holdings Transaction was 811,210 shares of Reliant Bancorp Common Stock and approximately $18,073 in cash. Reliant Bancorp did not issue fractional shares of Reliant Bancorp Common Stock in connection with the TCB Holdings Transaction, but paid cash in lieu of fractional shares based on the volume weighted average closing price per share of the Reliant Bancorp Common Stock on The Nasdaq Capital Market for the 10 consecutive trading days ending on and including December 30, 2019 (calculated as $22.36). At the effective time of the TCB Holdings Transaction, each outstanding option to purchase TCB Holdings common stock was canceled in exchange for a cash payment in an amount equal to the product of (i) $34.25 minus the per share exercise price of the option multiplied by (ii) the number of shares of TCB Holdings common stock subject to the option (to the extent not previously exercised). Reliant Bancorp paid aggregate consideration to holders of unexercised options of approximately $430.

Supplemental Pro Forma Combined Condensed Statements of Income Pro forma data for the three and six months ended June 30, 2020 and 2019 in the table below presents information as if the TCB Holdings Transaction and FABK Transaction occurred on January 1, 2019. These results combine the historical results of TCB Holdings and FABK into the Company's consolidated statement of income and, while certain adjustments were made for the estimated impact of certain fair value adjustments, they are not indicative of what would have occurred had the acquisitions taken place on the indicated date nor are they intended to represent or be indicative of future results of operations. In particular, no adjustments have been made to eliminate the amount of TCB Holdings' or FABK's provision for credit losses for the first three and six months of 2019 that may not have been necessary had the acquired loans been recorded at fair value as of the beginning of 2019. Additionally, these financials were not adjusted for non-recurring expenses, such as merger-related charges incurred by either the Company, TCB Holdings or FABK. The Company expects to achieve operating cost savings and other business synergies as a result of the acquisitions which are also not reflected in the pro forma amounts.

Leases	6 Months Ended

Leases [Abstract]
Leases	LEASES On January 1, 2020, the Company adopted ASU No. 2016-02 “Leases (Topic 842)” and all subsequent ASUs that modified Topic 842. The Company elected the prospective application approach provided by ASU 2018-11 and did not adjust prior periods for ASC 842. Leases with initial terms of less than one year are not recorded on the balance sheet. The Company’s long-term lease agreements are classified as operating leases. Certain of these leases offer the option to extend the lease term and the Company has included such extensions in its calculation of the lease liabilities to the extent the options are reasonably assured of being exercised. The lease agreements do not provide for residual value guarantees and have no restrictions or covenants that would impact dividends or require incurring additional financial obligations. The implementation of the new standard resulted in recognition of a right-of-use asset of $12.0 million and a lease liability of $11.9 million at the date of adoption, which is related to the Company’s lease of premises used in operations. The Company used a discount rate of 4.5% in determining the right-of-use asset and lease liability as of January 1, 2020. Information related to the Company's operating leases is presented below: June 30, 2020 Operating leases right of use assets $ 15,452    Operating lease liabilities $ 16,591    Weighted average remaining lease term (in years) 6.62 Weighted average discount rate 4.33  % The components of lease expense included in occupancy expenses for the three and six months ended June 30, 2020, were as follows: Three months ended June 30, 2020 Six months ended June 30, 2020 Operating lease cost $ 854    $ 1,482    Short-term lease cost —    —    Variable lease cost 98 178    Total lease cost $ 952    $ 1,660    The Company does not separate lease and non-lease components and instead elects to account for them as a single lease component. Variable lease cost primarily represents variable payments such as common area maintenance, utilities, and property taxes. Lease expense for the three and six months ended June 30, 2019, prior to the adoption of ASU 2016-02, was $678 and $1,371, respectively. A maturity analysis of operating lease liabilities and a reconciliation of undiscounted cash flows to the total operating lease liability is as follows: Lease payments due on or before June 30, 2020 June 30, 2021 $ 3,923    June 30, 2022 2,903    June 30, 2023 2,681    June 30, 2024 2,648    June 30, 2025 2,504    Thereafter 5,101    Total undiscounted cash flows 19,760    Discount on cash flows (3,169)   Total lease liability $ 16,591

Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Quarterly Report on Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with U.S. GAAP.  All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods covered by the report have been included.  The accompanying unaudited consolidated financial statements should be read in conjunction with Reliant Bancorp, Inc.’s consolidated financial statements and related notes appearing in Reliant Bancorp, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2019. The consolidated financial statements as of and for the periods presented include the accounts of Reliant Bancorp, Inc., Reliant Bank (the "Bank"), Community First Trups Holding Company ("TRUPS"), which is wholly owned by Reliant Bancorp, Inc., Reliant Risk Management, Inc. ("Risk"), which is wholly owned by Reliant Bancorp Inc., Reliant Investment Holdings, LLC ("Holdings"), which is wholly owned by the Bank, and Reliant Mortgage Ventures, LLC ("RMV"), of which the Bank controls 51% of the governance rights. Reliant Bancorp Inc., the Bank, TRUPS, Risk, Holdings, and RMV are collectively referred to herein as the “Company”. All significant inter-company balances and transactions have been eliminated in consolidation. As described in Note 12 to these unaudited consolidated financial statements, Reliant Bancorp, Inc. and TCB Holdings merged effective on January 1, 2020, and Reliant Bancorp, Inc. and FABK merged effective April 1, 2020. The accounting and reporting policies of the Company conform to U.S. GAAP and general practices in the banking industry.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to determination of the allowance for loan losses, the valuation of other real estate, the valuation of debt and equity securities, the valuation of deferred tax assets and fair values of financial instruments. The consolidated financial statements as of June 30, 2020, and for the three and six months ended June 30, 2020 and 2019, included herein have not been audited. The accounting and reporting policies of the Company conform to U.S. GAAP and Article 8 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although the Company believes that the disclosures made are adequate to make the information not misleading. The accompanying consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary to present a fair statement of the results for the interim periods presented. Such adjustments are of a normal recurring nature. The Company evaluates subsequent events through the date of filing. Certain prior period amounts have been reclassified to conform to the current period presentation. The results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020.
Recently Adopted Accounting Pronouncements and Newly Issued not yet Effective Accounting Standards	Recently Adopted Accounting Pronouncements Information about certain issued accounting standards updates is presented below. Also refer to Note 1 - Summary of Significant Accounting Policies, “Recent Authoritative Accounting Guidance” in the Annual Report on Form 10-K for the year ended December 31, 2019 for additional information related to previously issued accounting standards updates. ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 went into effect for the Company on January 1, 2020 and the Company elected the prospective application approach provided by ASU 2018-11 and did not adjust prior periods for ASC 842. The Company also elected certain practical expedients within the standard and consistent with such elections did not reassess whether any expired or existing contracts are or contain leases, did not reassess the lease classification for any expired or existing leases, and did not reassess any initial direct costs for existing leases. The effect of implementing this pronouncement resulted in right to use assets of $11,973 and a similar corresponding liability, as of January 1, 2020. ASU 2020-04, "Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting." In March 2020, the FASB issued Topic 848 amendments to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. It provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company has evaluated the effect of the pronouncement on the consolidated financial statements, noting no significant impact. Newly Issued not yet Effective Accounting Standards ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available for sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 is expected to be effective on January 1, 2023. We are currently evaluating the potential impact of ASU 2016-13 on the Company's financial statements. We are currently developing an implementation plan to include assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs, among other things. The adoption of ASU 2016-13 could result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, ASU 2016-13 will necessitate that we establish an allowance for expected credit losses for certain debt securities and other financial assets. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Financial Instruments - Credit Losses (ASC 326), Derivatives and Hedging (ASC 815), and Financial Instruments (ASC 825). The amendments in this ASU improve the codification by eliminating inconsistencies and providing clarifications. The amended guidance in this ASU related to credit losses will be effective for the Company for fiscal years and interim periods beginning after December 15, 2022. The Company is currently evaluating the impact of these ASUs on the Company’s consolidated financial statements. While we are currently unable to reasonably estimate the impact of adopting these ASUs, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of the Company's loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date. ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for the Company on January 1, 2021, with earlier adoption permitted and is not currently expected to have a significant impact on the Company's consolidated financial statements as it simplifies the test of impairment of goodwill.
