FORWARD-LOOKING STATEMENTS

Reliant Bancorp, Inc. (“Reliant Bancorp” or the “Company”) may from time to time make written or oral statements, including statements contained in this report (including, without limitation, certain statements in Item 2 (Management’s Discussion and Analysis of Financial Condition and Results of Operations)), that constitute 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 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:  

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

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

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

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

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

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

(vii) lack of strategic growth opportunities or our failure to execute on those opportunities;

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

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

(x) the impact of competition with other financial institutions and financial services providers, including pricing pressures and the resulting impact on Reliant Bancorp’s results, including as a result of compression to net interest margin;

(xi) our ability to effectively manage problem credits;

(xii) our ability to successfully implement efficiency initiatives on time and in amounts projected;

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

(xiv) the impact of negative developments in the financial industry and U.S. and global capital and credit markets;

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

(xvi) our ability to adapt to technological changes;

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

(xviii) the vulnerability of Reliant Bank’s network and online banking portals, and the systems of parties with whom Reliant Bancorp and Reliant Bank contract, to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss, and other security breaches;

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

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

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

You should also consider carefully the risk factors discussed in Part I of our most recent Annual Report on Form 10-K, which address additional factors that could cause our actual results to differ from those set forth in the 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 there listed may develop or, if currently extant, we may not have yet recognized them.

The 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.

RELIANT BANCORP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

MARCH 31, 2019 (UNAUDITED) AND DECEMBER 31, 2018

(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. began organizational activities in 2005. Reliant Bancorp, Inc. provides financial services through its offices in Williamson, Robertson, Davidson, Sumner, Rutherford, Maury, Hickman and Hamilton Counties in Tennessee. Its primary deposit products are checking, savings, and term certificate accounts, and its primary lending products are commercial and residential construction loans, commercial loans, installment loans and lines secured by home equity. Substantially all loans are secured by specific items of collateral including commercial and residential real estate, business assets, and consumer assets.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to 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, 2018.

The consolidated financial statements as of and for the periods presented include the accounts of Reliant Bancorp Inc., Reliant Bank, Community First TRUPS Holding Company, which is wholly owned by Reliant Bancorp Inc., (“TRUPS”), Reliant Investment Holdings, LLC ("Holdings") of which is 100% wholly owned by Reliant Bank ("Bank"), and Reliant Mortgage Ventures, LLC ("RMV"), of which the Bank controls 51% of the governance rights. Reliant Bancorp Inc., Reliant Bank, TRUPS, Holdings and RMV, are collectively referred to herein as the “Company”. As described in the notes to our annual consolidated financial statements, all significant inter-company balances and transactions have been eliminated in consolidation. As described in Note 12, Reliant Bancorp, Inc. and Community First, Inc. merged effective January 1, 2018. 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.

MARCH 31, 2019 (UNAUDITED) AND DECEMBER 31, 2018

(Dollar amounts in thousands except per share amounts)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Use of Estimates (Continued)

The consolidated financial statements as of March 31, 2019, and for the three months ended March 31, 2019 and 2018, 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 are, in the opinion of management, 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 months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

Reclassifications

Certain reclassifications were made to the March 31, 2018 financial statement presentation in order to conform to the March 31, 2019 financial statement presentation. Total stockholders' equity and net income are unchanged due to these reclassifications.

NOTE 2 - SECURITIES

The amortized cost and fair value of available for sale securities and the related gross unrealized gains and losses recognized in accumulated other comprehensive gain (loss) at March 31, 2019 and accumulated other comprehensive income at December 31, 2018 were as follows:

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 127 and 242 securities in an unrealized loss position as of March 31, 2019 and December 31, 2018, respectively.

Risk characteristics relevant to each portfolio segment are as follows:

Commercial,industrialand 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.

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED)

Multi-family and commercial real estate: Multi-family and commercial real estate and multi-family 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 securing 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 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 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.

1-4family residential real estate: Residential real estate loans 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 residential property values impact the depth of potential losses in this portfolio segment.

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED)

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 residential property 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. 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. 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 March 31, 2019 and December 31, 2018:

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED)

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. Borrower 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.

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED)

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.

NOTE 4 - OTHER REAL ESTATE

In connection with the merger with Community First, the Company acquired three real estate parcels. The Company valued the properties at their estimated fair values less costs to sell which totaled $1,650. Expenses related to other real estate totaled $6 and $3 for the quarters ended March 31, 2019 and 2018, respectively.

At March 31, 2019, there were two 1-4 Family Residential loans with related balances totaling $1,902 and a Commercial, Industrial and Agricultural loan, with a related balance of $160, in the process of foreclosure.

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;

•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.

NOTE 5 - FAIR VALUES OF ASSETS AND LIABILITIES (CONTINUED)

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 impaired loans 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.

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.

NOTE 5 - FAIR VALUES OF ASSETS AND LIABILITIES (CONTINUED)

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

Stock Option Plan

In 2006, the Board of Directors and shareholders of the Bank approved the Commerce Union Bank Stock Option Plan (the “Plan”). The Plan provides for the granting of stock options, and authorizes the issuance of common stock upon the exercise of such options, for up to 625,000 shares of common stock to employees and organizers of the Company. As part of reorganization, all Commerce Union Bank options were replaced with Commerce Union Bancshares, Inc. options with no change in terms. On March 10, 2015, the shareholders of the Company approved the Commerce Union Bancshares, Inc. Amended and Restated Stock Option Plan that permits the grant of awards of up to 1,250,000 shares of the Company

common stock in the form of stock options. As part of the merger with Reliant Bank, all outstanding stock options of Reliant Bank were converted to stock options of Commerce Union Bancshares, Inc. under this plan.

Under the Stock Option 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 ten 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 the common stock on the grant

date.

NOTE 7 - REGULATORY CAPITAL REQUIREMENTS

The Company and the Bank are subject to regulatory capital requirements administered by the federal and state banking agencies. 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 March 31, 2019, the Company and the Bank meet all capital adequacy requirements to which they are subject.

Prompt corrective action regulations provide five 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 March 31, 2019 and December 31, 2018, 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 FDIC approved final rules that substantially amend the regulatory risk-based capital rules applicable to the Company 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 Act.

Under these rules, the leverage and risk-based capital ratios of bank holding companies 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.

NOTE 7 - REGULATORY CAPITAL REQUIREMENTS (CONTINUED)

Basel III establishes a “capital conservation buffer” of 2.5% which began phasing in on January 1, 2016, at a rate of 0.625% per year. The buffer became fully phased in on January 1, 2019. 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.

Actual and required capital amounts and ratios are presented below as of March 31, 2019 and December 31, 2018.

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 underwritten to participating banks or other investor group standards.

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 $60,000 as of March 31, 2019 , were designated as cash flow hedges of certain certificates of deposits 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 March 31, 2019, is as follows:

Notional amounts	$	60,000
Weighted average pay rates	3.338		%
Weighted average receive rates	3.060		%
Weighted average maturity	4.22 years

NOTE 11 – INCOME TAXES

Income tax expense for the three months ended March 31, 2019 and 2018 was $372 and $797. The decline is attributable to; a lower income before tax level, an increased level of tax-exempt income in 2019, increased utilization of state tax credit lending programs, and there were no non-deductible merger expenses in 2019. The effective tax rate for the three months ended March 31, 2019 and 2018 was 14% and 20%, respectively.

NOTE 13 - RECENT 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 our 2018 Form 10-K for additional information related to previously issued accounting standards updates.

ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” implements a common revenue standard that clarifies the principles for recognizing revenue. The principle element of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 was originally going to be effective for the Company on January 1, 2018; however, the FASB recently issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date" which deferred the effective date of ASU 2014-09 by one year to January 1, 2019. Revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. The adoption of this standard did not have a significant impact on the Company.

ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment,

(iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to

estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance

sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (viii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. ASU 2016-01 became effective for us on January 1, 2019 and did not have a significant impact on our financial statements.

ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 will require 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 will be effective for us on January 1, 2020 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements. We estimate that the effect of implementing this pronouncement will result in right to use assets of $13,804 and a corresponding liability, using the remaining contractual lease periods. We also estimate the impact on regulatory capital to be a reduction of eight basis points to the Tier 1 leverage capital ratio. Management is presently evaluating the planned renewals of existing leases. If management determines to utilize the renewals of leases then the right to use assets and corresponding liability will increase.

NOTE 13 - RECENT ACCOUNTING PRONOUNCEMENTS (CONTINUED)

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 will be effective on January 1, 2021. We are currently evaluating the potential impact of ASU 2016-13 on our 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. We are also in the process of implementing a third-party vendor solution to assist us in the application of the ASU 2016-13. The adoption of the 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. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our 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 consolidated financial statements.

ASU 2018-13, “Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this update remove disclosures that no longer are considered cost beneficial, modify/clarify the specific requirements of certain disclosures, and add disclosure requirements identified as relevant. ASU 2018-13 will be effective for the Company on January 1, 2021, with early adoption permitted, and is not expected to have a significant impact on our financial statements.

Item2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

Executive Summary

The following is a summary of the Company’s financial highlights and significant events for the three months endedMarch 31, 2019:

• Net income available to common shareholders totaled $3.8 million, or $0.33 per diluted common share, for the three months endedMarch 31, 2019 compared to $3.7 million, or $0.33 per diluted common share, during same period in 2018.

• Loans, net of unearned income increased $31.1 million for the three months endedMarch 31, 2019.

• Deposits increased $73.4 million for the three months endedMarch 31, 2019.

• Asset quality remains strong with nonperforming assets to total assets of just 0.45 percent.

In the following section the term “Company” means “Reliant Bancorp, Inc. and all of its subsidiaries” and the term “Bank” means “Reliant Bank.” The following discussion and analysis is intended to assist in the understanding and assessment of significant changes and trends related to our financial position and operating results. This discussion and analysis should be read in conjunction with our consolidated financial statements and the related notes included elsewhere herein along with our 10-K filed March 8, 2019. Amounts in the narrative are shown in thousands, except for economic and demographic information, numbers of shares, per share amounts and as otherwise noted.

Critical Accounting Policies

The accounting principles we follow and our methods of applying these principles conform to accounting principles generally accepted in the United States of America ("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, 2018. The following is a brief summary of the more significant policies.

Principles of Consolidation

The consolidated financial statements as of and for the periods presented include the accounts of Reliant Bancorp, the Bank, Community First Trups Holding Company, which is wholly owned by Reliant Bancorp (“TRUPS”), Reliant Investment Holdings, LLC ("Holdings"), which is 100% wholly owned by the Bank, and Reliant Mortgage Ventures, LLC ("RMV"), of which the Bank controls 51% of the governance rights (Reliant Bancorp, the Bank, Holdings, TRUPS, and RMV are collectively referred to herein as the “Company”). As described in the notes to our annual consolidated financial statements, RMV is considered a variable interest entity for which the Bank is deemed to be the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation. As described in Note 12, Reliant Bancorp and Community First, Inc. merged effective January 1, 2018. The accounting and reporting policies of the Company conform to U.S. GAAP and to general practices in the banking industry.

During 2011, the Bank and another entity organized RMV. Under the related 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 via additional capital contributions to RMV. As of March 31, 2019, RMV's cumulative losses to date totaled $9,601. RMV will have to generate net income of this amount before the Company will participate in future cash flow distributions.

37

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 acquired loans at fair value as of the date of the merger (discussed below), 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 establishes an allowance for loan losses subsequent to the date 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 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 merger and that are accounted for under ASC 310-20, the historical loss estimates are based on the historical losses experienced by Reliant Bank for loans with similar characteristics as those acquired other than purchased credit-impaired loans. We record an allowance for loan losses only when the calculated amount exceeds the remaining credit mark established at acquisition.

Allowance for Loan Losses

The allowance for loan losses 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.

A loan is impaired when full payment under the loan terms is not expected. All classified loans and loans on non-accrual 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 loans 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 the 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.

COMPARISON RESULTS OF OPERATIONS FOR THETHREE MONTHSENDEDMARCH 31, 2019AND 2018

Merger Between Reliant Bancorp, Inc. and Community First, Inc.

On December 15, 2017, the shareholders of Reliant Bancorp approved a merger with Community First, Inc. ("Community First"), which became effective on January 1, 2018 (the "Merger”). Each outstanding share of Community First common stock converted into the right to receive .481 shares of Reliant Bancorp common stock. After the Merger was completed, legacy Reliant Bancorp’s shareholders owned approximately 78.9% of the common stock of the combined company, and legacy Community First’s shareholders owned approximately 21.1% of the common stock of the combined company.

The assets and liabilities of Community First as of the effective date of the Merger were recorded at their respective estimated fair values and added to those of the Company. Any excess of purchase price over the net estimated fair values of the acquired assets and assumed liabilities of Community First was allocated to all identifiable intangibles assets. Any remaining excess was then allocated to goodwill.

As of December 31, 2017, Community First, including its wholly owned subsidiaries, had total assets of $480 million, total loans of $316 million and total deposits of $433 million. Community First held a loan portfolio that was primarily comprised of real estate loans.

As a result of the Merger on January 1, 2018, the Company:

• grew consolidated total assets from $1,125.0 million to $1,636.0 million as of January 1, 2018 after giving effect to purchase accounting;

• increased total loans from $762.5 million to $1,075.5 million as of January 1, 2018;

• increased total deposits from $883.5 million to $1,316.9 million as of January 1, 2018; and

• expanded its employee base from 167 full time equivalent employees to 272 full time equivalent employees as of January 1, 2018.

Earnings

Net income attributable to common shareholders amounted to $3,824, or $0.34 per basic share, for the three months ended March 31, 2019, compared to $3,741, or $0.33 per basic share, for the same period in 2018. Diluted net income attributable to common shareholders was $0.33 per share for the three months ended March 31, 2019 and March 31, 2018. The increase of 0.6% in net interest income for the three months ended March 31, 2019 compared to the same period in 2018 accounts for all of the increase in net income attributable to common shareholders. This and other components of earnings are discussed further below.

39

Net Interest Income

Net interest income represents the amount by which interest earned on various earning assets exceeds interest paid 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 spread and net interest margin for the three months ended March 31, 2019, and 2018 (dollars in thousands):

Table Assumptions—Average loan balances are inclusive of nonperforming loans. Yields computed on tax-exempt instruments are on a tax equivalent basis including a state tax credit included in loan yields of $300 and $25 for the three months ended March 31, 2019 and 2018, respectively. 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 months ended March 31, 2019, we recorded net interest income of approximately $13.5 million which resulted in a net interest margin (net interest income divided by the average balance of interest earning assets) of 3.63%. For the three months ended March 31, 2018, we recorded net interest income of approximately $13.4 million, which resulted in a net interest margin of 3.79%. The main factor contributing to the slight increase in our net interest income was our increase in our loans and the related yield. It was partially offset by the increase in our cost of funds.

Our year-over-year average loan volume increased by approximately 13.8% for the first three months of 2019 compared to the first three months of 2018. Our combined loan and loan fee yield increased from 5.07% to 5.39% for the first three months of 2019 compared to 2018. The increased yield for the three months ended March 31, 2019 is attributable to a 34 basis points increase in contractual loan yields, a nine basis points increase in state tax credits, and partially offset by an eight basis points decrease in purchase accounting accretion and a three basis points decrease in loan fees.

Our tax equivalent yield on tax-exempt investments increased to 3.86% for the three months ended March 31, 2019, from 3.57% for the same period in 2018. This increase was driven by investment restructurings in the first quarter of 2018. Our year-over-year average tax-exempt investment volume increased by approximately 4.7% for the first three months of 2019 compared to the same period in 2018. Our year-over-year average taxable securities volume decreased by 0.3% for the first three months of 2019 compared to the same period in 2018. No material changes to our investment portfolio were made during the first quarter of 2019.

Our cost of funds increased to 1.44% from 0.86% for the three months ended March 31, 2019 compared to the same period in 2018. The increase in our cost of funds was driven mainly by higher rates being paid on time deposits, FHLB advances, and subordinated debt. We experienced a 0.7%decrease in our average non-interest bearing deposits from the three months ended March 31, 2018.

Our balance sheet has some components that will benefit from rising interest rates, including variable rate loans, some variable rate investment securities and interest rate swaps.  Conversely our interest bearing liabilities are negatively impacted with rising interest rates. Our wholesale fundings are particularly sensitive to changes in interest rates mainly due to their short term nature. We added $30 million of pay-fixed receive-variable interest rate swaps in each of the second and third quarters of 2018. We are always looking for opportunities to increase our non-interest bearing and lower cost deposits and have seen some success with a stronger focus on low cost deposits in all of our sales incentive plans.  These efforts will continue as well as continuing to evaluate the benefits of fixing a greater portion of our funding costs through interest rate swaps.

Provision for Loan Losses

The provision for loan losses represents a charge to earnings necessary to establish an allowance for loan losses that, in management’s evaluation, should be adequate to provide coverage for the inherent losses on outstanding loans. Based upon management’s assessment of the loan portfolio, we adjust our allowance for loan losses on a quarterly basis to an amount deemed appropriate to adequately cover probable losses inherent in the loan portfolio.

Based upon our evaluation of the loan portfolio, we believe the allowance for loan losses to be adequate to absorb our estimate of probable losses existing in the loan portfolio at March 31, 2019. While policies and procedures used to estimate the allowance for loan losses, as well as the resultant provision for loan losses charged to operations, are considered adequate by management, they are necessarily approximate and imprecise. There are factors beyond our control, such as conditions in the local and national economy, local real estate market, or particular industry or borrower-specific conditions, which may materially negatively impact our asset quality and the adequacy of our allowance for loan losses and, thus, the resulting provision for loan losses.

We recorded no provision for loan losses for the three months ended March 31, 2019 compared to $137 for loan losses recorded for the three months ended March 31, 2018. Our provision for loan losses was impacted by the level of loan growth, the credit quality of the loan portfolio, and the amount of net recoveries for the three months ended March 31, 2019.

Non-Interest Income

Our non-interest income is composed of several components, some of which vary significantly between periods. The following is a summary of our non-interest income for the three months ended March 31, 2019, and 2018 (dollars in thousands):

41

	Three Months Ended March 31,				Dollar Increase			Percent Increase
	2019		2018		(Decrease)			(Decrease)
Non-Interest Income
Service charges and fees	$	884	$	771	$	113		14.7	%
Securities gains, net	131		—		131			100.0	%
Gains on mortgage loans sold, net	560		1,705		(1,145		)	(67.2	)%
Gain on sale of other real estate	—		89		(89		)	(100.0	)%
Other noninterest income:
Bank-owned life insurance	279		302		(23		)	(7.6	)%
Brokerage revenue	11		75		(64		)	(85.3	)%
Miscellaneous noninterest income	73		49		24			49.0	%
Total other non-interest income	363		426		(63		)	(14.8	)%
Total non-interest income	$	1,938	$	2,991	$	(1,053	)	(35.2	)%

The most significant reasons for the changes in total non-interest income during the three months ended March 31, 2019 compared to the same periods in 2018 are the fluctuation in gains on mortgage loans sold, net, the increase in service charges, and the gains on securities transactions. These and other factors impacting non-interest income are discussed further below.

Service charges on deposit accounts have increased and mainly reflect customer growth trends but have also been impacted by changes in our fee structures. The majority of the 14.7%increase for the three months ended March 31, 2019 was driven by the changes in our fee structures.

Securities gains and losses often fluctuate from period to period and can sometimes be attributable to various balance sheet risk strategies. During the three months ended March 31, 2019, the Company sold securities classified as available for sale totaling $10,558 with a gain of $131. During the three months ended March 31, 2018, the Company sold securities classified as available for sale totaling $82,187 with no gain.

Gains on mortgage loans sold, net, consists of fees from the origination and sale of mortgage loans and first-lien HELOCs. These mortgage fees are for loans originated and subsequently sold to third-party investors. All of these loan sales transfer servicing rights to the buyer. 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 the venture’s products in the secondary markets. Gains on mortgage loans sold, net, amounted to $560 for the three months ended March 31, 2019, compared to $1,705 for the same period in the prior year. 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.

During the three months ended March 31, 2019, there was no gain or loss due to the sale of other real estate compared to a gain of $89 in the same period in 2018.

Non-interest income also includes appreciation in the cash surrender value of bank-owned life insurance which was $279 for the three months ended March 31, 2019, compared to $302 for the same period in 2018. The decrease relates to the introductory rate ending from our last purchase.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.

Our brokerage revenue is solely based on commissions received from established referral relationships and fluctuate based on assets under management.

Non-Interest Expense

The following is a summary of our non-interest expense for the three months ended March 31, 2019 and 2018 (dollars in thousands):

42

	Three Months Ended March 31,				Dollar Increase			Percent Increase
	2019		2018		(Decrease)			(Decrease)
Non-Interest Expense
Salaries and employee benefits	$	7,265	$	6,954	$	311		4.5	%
Occupancy	1,352		1,229		123			10.0	%
Information technology	1,410		1,349		61			4.5	%
Advertising and public relations	254		89		165			185.4	%
Audit, legal and consulting	796		623		173			27.8	%
Federal deposit insurance	195		196		(1		)	(0.5	)%
Merger expenses	2		177		(175		)	(98.9	)%
Other operating	1,472		1,545		(73		)	(4.7	)%
Total non-interest expense	$	12,746	$	12,162	$	584		4.8	%

The most significant reason for the increase in total non-interest expense of $584 or 4.8% for the three months ended March 31, 2019 is due to additional staffing for our mortgage venture and opening our new branches in Murfreesboro and Chattanooga as well as our investment in revenue producers. These and other factors impacting non-interest expense are discussed further below.

Salaries and employee benefits increased by $311 or 4.5% for the three months ended March 31, 2019 compared to the same period in 2018. This increase is attributable mainly to the increased staff for our mortgage venture as well as our staffing of our new branches in Murfreesboro and Chattanooga and other investments in revenue producers.

Certain of our facilities are leased while there are others that we own. Primarily, occupancy costs increased$123 or 10.0% during the three months ended March 31, 2019 when compared to the same period in 2018 due to the lease for a new executive office which opened in the second quarter of 2018, the lease for the Murfreesboro branch which opened in the third quarter of 2018, and the lease for the Chattanooga branch which opened in the fourth quarter of 2018.

Information technology costs increased by $61 or 4.5% when comparing the three months ended March 31, 2019 to the comparable period in 2018. This increase is mainly attributable to increased costs due to increasing the volume of accounts and transactions as well as our continued investment in information security and other technology.

Advertising and public relations costs increased by $165 or 185.4% when comparing the three months ended March 31, 2019 to the same period in 2018. The increase was attributable to an increase in advertising for our mortgage venture as well as cost associated with a brand initiative campaign and an increase in donations and sponsorships.

Audit, legal and consulting costs increased by $173 or 27.8% when comparing the three months ended March 31, 2019 to the same period in 2018. This increase is mainly attributable to the increase in legal fees and consulting fees incurred in connection with our mortgage venture.

Our Federal Deposit Insurance Corporation (FDIC) 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 decreased by $1 for the three months ended March 31, 2019, compared to the same period in 2018. This slight decrease is primarily the result of a decrease of the rates charged by the FDIC which was offset by our increase in deposits.

Merger related expenses decreased by 98.9% to $2 for the three months ended March 31, 2019 when compared to the same period in 2018. These costs are considered one time expenses associated with the Merger, and most of these expected expenses have been incurred at this point.

Other operating expenses decreased by $73 or 4.7% for the three months ended March 31, 2019, compared to the same period in 2018 mainly due to the decrease in loan-related expenses such as processing costs based on volume for the three months ended March 31, 2019.

Income Taxes

During the three months ended March 31, 2019, we recorded consolidated income tax expense of $372 compared to $797 for the three months ended March 31, 2018. The Company files separate federal tax returns for the operations of the mortgage banking

43

and banking operations. The taxable income or losses of the mortgage banking operations are included in the respective returns of the Bank and non-controlling members for federal purposes.

Our income tax expense attributable to shareholders for the three months ended March 31, 2019, reflects an effective income tax rate of 11.2% (exclusive of a tax benefit from our mortgage banking operations of $108 on pre-tax losses of $1,651), compared to 18.1% (exclusive of a tax benefit of $29 on pre-tax losses of $493 from our mortgage banking operations for the comparable period of 2018). Our tax rate for the three months ended March 31, 2019, was favorably influenced by the increase in state tax credits of $275.

Noncontrolling Interest in NetLossof Subsidiary

Our non-controlling interest in net loss of subsidiary is solely attributable to Reliant Mortgage Ventures, LLC. Reliant Bank has a 51% voting interest in this venture. Under the terms of the related operating agreement, the non-controlling member receives 70% of the cash flow distributions of the mortgage venture, and the Bank receives 30% of any cash flow distributions, after the non-controlling member recovers its capital contributions to the venture. The non-controlling member is required to fund the mortgage venture's losses via additional capital contributions to the mortgage venture. The venture had a net loss of $1,543 for the three months ended March 31, 2019 compared to a net loss of $464 for the same period in 2018. The increase in loss for the three months ended March 31, 2019 when compared to the same period in 2018 is mainly attributable to the increase in salaries and benefits due to the increased staff as well as legal fees and consulting fees previously mentioned. These amounts are included in our consolidated results. Also, see Note 9 for segment reporting in the consolidated financial statements included elsewhere herein.

COMPARISON OF BALANCE SHEETS ATMARCH 31, 2019ANDDECEMBER 31, 2018

Overview

The Company’s total assets were $1,761,926 at March 31, 2019 and $1,724,338 at December 31, 2018. Our assets increased by 2.2% from December 31, 2018 to March 31, 2019. The increase was substantially attributable to the growth in net loans and investments during the period of $30.6 million or 2.5% and $14.0 million or 4.7%, respectively, discussed further below. These increases were partially offset by the decline of mortgage loans held for sale by $5.8 million or 36.9%. The Company’s total liabilities were $1,546,807 at March 31, 2019 and $1,515,924 at December 31, 2018, an increase of 2.0%. The increase in liabilities from December 31, 2018 to March 31, 2019, was substantially attributable to the increase in deposits of $73.4 million or 5.1% and the increase was partially offset by the decrease in Federal Home Loan Bank (FHLB) advances of $42 million or 73.4% during the period. These and other components of our balance sheets are discussed further below.

Loans

Lending-related income is the most important 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 discussed 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. Early payoffs typically increase in lowering rate environments as customers identify advantageous opportunities for refinancing. We have been adding experienced lending officers to our staff to help with loan growth. In the first quarter of 2017 we expanded outside Middle Tennessee into Chattanooga, one of the state’s fastest growing metropolitan markets, and with the Merger we have expanded our Middle Tennessee footprint into Maury and Hickman Counties. Total loans, net, at March 31, 2019, and December 31, 2018, were $1,250,806 and $1,220,184, respectively. This represented an increase of 2.5% from December 31, 2018 to March 31, 2019.

The table below provides a summary of the loan portfolio composition for the dates noted (including purchased credit-impaired (PCI) loans).

Commercial, industrial and agricultural loans above consist solely of loans made to U.S. domiciled customers. These include loans for use in normal business operations to finance working capital needs, equipment purchases, or other expansionary projects. Commercial, industrial, and agricultural loans of $218,767 at March 31, 2019, increased2.3% compared to $213,850 at December 31, 2018.

Real estate loans comprised 80.1% of the loan portfolio at March 31, 2019. Residential loans included in this category consist mainly of closed-end loans secured by first and second liens that are not held for sale and revolving, open-end loans secured by 1-4 family residential properties extended under home equity lines of credit. The Company increased the residential portfolio 2.3% from December 31, 2018 to March 31, 2019. Multi-family and commercial loans included in the real estate category above include (in typical order of prominence) loans secured by non-owner-occupied nonfarm nonresidential properties, loans secured by owner-occupied nonfarm nonresidential properties, and loans secured by multi-family residential properties. Multi-family and commercial real estate loans of $469,468 at March 31, 2019, increased 4.8% compared to the $447,840 held as of December 31, 2018. Real

45

estate construction loans consist of 1-4 family residential construction loans, other construction loans, land loans, and loans secured by farmland. Construction lending has increased since 2016 based on a strong local economy.

Consumer loans mainly consist of loans to individuals for household, family, and other personal expenditures under revolving credit plans and other consumer loans. We have a small amount of credit card loans on our balance sheet due to the implementation of a new credit card program during the third quarter of 2017. We have a relatively small number of automobile loans. Our consumer loans experienced a decrease from December 31, 2018, to March 31, 2019, of 12.5%.

Other loans consist mainly of loans to states and political subdivisions and loans to other depository institutions and experienced an increase of 0.8% from December 31, 2018 to March 31, 2019.

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 March 31, 2019, excluding unearned net fees and costs.

	One Year or Less		One to Five Years		Over Five Years		Total
Gross loans	$	414,547	$	552,364	$	295,283	$	1,262,194
Fixed interest rate							$	768,000
Variable interest rate							494,194
Total							$	1,262,194

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

We maintain an allowance for loan losses that we believe is adequate to absorb the probable incurred losses inherent in our loan portfolio. 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.

A loan is impaired when full payment under the loan terms is not expected. All classified loans and loans on non-accrual 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 loans remaining principal balance, are recorded as recoveries of prior charge-offs until these charge-offs have been fully recovered.

At March 31, 2019, the allowance for loan losses was $11,354 compared to $10,892 at December 31, 2018. The allowance for loan losses as a percentage of total loans was 0.90% at March 31, 2019 compared to 0.88% at December 31, 2018.

Nonperforming Assets

Non-performing assets consist of non-performing loans plus real estate acquired through foreclosure or deed in lieu of foreclosure. Non-performing loans by definition consist of non-accrual loans and loans past due 90 days or more and still accruing interest. When we place a loan on non-accrual 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 Company’s non-performing assets.

	March 31, 2019			December 31, 2018

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 minimal credit exposure to the Company 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 are a significant component of the Company’s earning assets. Securities totaled $310,305 at March 31, 2019. This represents a 4.7% increase from the December 31, 2018 total of $296,323. Our growth is attributable to the Merger and the planned investment securities restructuring, mentioned previously, that began in the fourth quarter of 2017. The increase is attributable to purchasing $20,571 securities available for sale during the three months ended March 31, 2019, offset by sales of $10,558, and principal paydowns and maturities of $2,291 during the same period.

Restricted equity securities totaled $11,499 and $11,690 at March 31, 2019, and December 31, 2018, respectively, and consist of Federal Reserve Bank and Federal Home Loan Bank stock.

The following table shows the Company’s investments’ amortized cost and fair value, aggregated by investment category for the periods presented:

Premises and Equipment

Premises and equipment, net, totaled $21,970 at March 31, 2019 compared to $22,033 at December 31, 2018, a net decrease of $63 or 0.3%. Premises and equipment purchases amounted to approximately $434 during the first three months of 2019 and were mainly incurred for additional leasehold improvements for our branches and new mortgage locations while depreciation expense amounted to $497. At March 31, 2019, we operated from seventeen retail banking locations as well as six stand-alone mortgage loan production offices. Two of our bank branch locations, including our main office, are in Brentwood, Tennessee. Of our other fifteen bank branch locations three are in Columbia, the remaining are in Franklin, Springfield, Gallatin, Nashville, Murfreesboro, Mt. Pleasant, Thompson Station, Centerville, Lyles, and Chattanooga, Tennessee. As of March 31, 2019, our mortgage loan production offices were located Brentwood, Hendersonville, and Chattanooga, Tennessee as well as two in Little Rock, Arkansas and one in Timonium, Maryland.

Deposits

Deposits represent the Company’s largest source of funds. The Company competes with other bank and nonbank 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 price 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 March 31, 2019, total deposits were $1,511,321, an increase of $73,418, or 5.1%, compared to $1,437,903 at December 31, 2018. During the first three months of 2019, non-interest bearing demand deposits increased by $4.0 million, interest-bearing demand deposits decreased by $10.1 million, savings and money market deposits decreased by $2.9 million, and time deposits increased by $82.4 million. A substantial portion of the increase in the deposits is attributable to time deposits with the state of Tennessee as part of our strategy to lower our funding costs.

The following table shows maturity or repricing of time deposits of $250 or more by category based on time remaining until maturity at March 31, 2019.

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 on-balance sheet and 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 were in compliance with our policy as of March 31, 2019. 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 and other shortcomings, we rely more heavily on the earnings simulation model and the economic value of equity model discussed further below.

50

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 variance 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	2.1%	(15)%	(2.3)%	(15)%
-100 bp	1.7%	(10)%	0.4%	(10)%
+100 bp	(1.0)%	(10)%	(0.4)%	(10)%
+200 bp	(1.7)%	(15)%	(0.3)%	(15)%
+300 bp	(2.4)%	(20)%	(0.4)%	(20)%
+400 bp	(3.5)%	(25)%	(0.9)%	(25)%

We were in compliance with our earnings simulation model policies as of March 31, 2019, indicating what we believe to be a fairly neutral interest-rate risk profile.

Economic value of equity—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
+100 bp	15%
+200 bp	25%
+300 bp	30%
+400 bp	35%
Non-parallel shifts	35%

At March 31, 2019, 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 mortgage 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 March 31, 2019, advances totaled $15,309 compared to $57,498 as of December 31, 2018. The decrease in FHLB advances generally is attributable to our increase in deposits, mainly our increase in time deposits from the state of Tennessee, and the decrease in our mortgage loans held for sale and somewhat offset by our increase in loans and securities.

At March 31, 2019, 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
2019	$	11,000	2.52%
2020	—		—%
2021	356		2.73%
2022	711		1.22%
2023	2,600		1.94%
Thereafter	642		2.47%
	$	15,309	2.36%

The Company has issued $23.0 million of subordinated debentures in connection with TRUPS issued by trusts that are affiliates of the Company, $10.0 million of which is owned by a wholly owned subsidiary of the Company.  The Company has timely made its scheduled interest payments on these subordinated debentures since assumed in the first quarter of 2018.  As of March 31, 2019, the Company was current on all interest payments due related to its subordinated debentures.  The Company 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 the Company cannot pay any dividends on its common stock or preferred stock.

Capital

Stockholders’ equity was $215,119 at March 31, 2019, an increase of $6,705, or 3.2%, from $208,414 at December 31, 2018. During the three months ended March 31, 2019, the Company raised $28 of capital through the exercise of Company stock options and purchased $659 of its common stock as part of its previously announced share repurchase program. The accretion of earnings to capital which was offset by the declared dividends, net stock purchase, and the increase in assets led to a decrease in the Bank’s March 31, 2019 Tier 1 leverage ratio to 9.99% compared with 10.17% at December 31, 2018 (see other ratios discussed further below). Additionally, the subordinated debentures qualify as Tier 1 and Total risk-based capital for the Company. Common dividends of $1,036 (of which $1,036 were declared in the prior year) were paid during the three months ended March 31, 2019, and common dividends of $1,035 were declared in the first quarter of 2019 and were paid subsequent to quarter end.

On July 14, 2017, the Company filed a Form S-3 registration statement 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) depositary 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 any 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.

Banks as regulated institutions are required to meet 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 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 the guidelines. We regularly review our capital adequacy to ensure compliance with these 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 return.

Prompt corrective action regulations provide five 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 March 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 these notifications that management believes have changed the institution’s category. Actual and required capital amounts and ratios are presented below as of March 31, 2019 and December 31, 2018 for the Company and Bank.

Effects of Inflation and Changing Prices

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles, which require the measurement of financial position 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’ increased 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 shareholders’ equity. Commercial and other loan originations and refinancings 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 were as follows at March 31, 2019:

	March 31, 2019
Unused lines of credit	$	261,188
Standby letters of credit	18,056
Total commitments	$	279,244

Other Off Balance Sheet Arrangements

The total notional amount of swap agreements was $81,505 at March 31, 2019 and December 31, 2018. At March 31, 2019, the contracts had negative fair values totaling $1,854 recorded. At December 31, 2018, the contracts had negative fair values totaling $542 recorded.

Emerging Growth Company Status

The Company is 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 the Company chooses to comply with the reporting requirements of public companies that are not emerging growth companies, the Company may avail itself of the reduced requirements applicable to emerging growth companies from time to time in the future, so long as the Company is an emerging growth company. The Company will remain an emerging growth company for an initial five year period, though it may cease to be an emerging growth company earlier under certain circumstances, including if, before the end of such five years, it is deemed to be a large accelerated filer under the rules of the SEC (which depends on, among other things, having a market value of common stock held by non-affiliates in excess of $700 million) or if total annual gross revenues equal or exceed $1.07 billion in a fiscal year. Management cannot predict if investors will find the Company’s common stock less attractive because it will rely on these exemptions. If some investors find the Company’s common stock less attractive as a result, there may be a less active trading market for its common stock and the Company’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. The Company 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.

Item 4.    Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Management, including our President and Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this report. Based upon that evaluation, our President and Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported as and when required and (ii) accumulated and communicated to our management, including our President and Chief Executive Officer and the Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during the three months endedMarch 31, 2019, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.Legal Proceedings.

Reliant Bancorp and its wholly-owned subsidiary, Reliant Bank, are periodically involved as a plaintiff or defendant in various legal actions in the ordinary course of its business. Neither Reliant Bancorp nor Reliant 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 Reliant Bank’s financial condition or Reliant Bancorp’s consolidated financial position.

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. began organizational activities in 2005. Reliant Bancorp, Inc. provides financial services through its offices in Williamson, Robertson, Davidson, Sumner, Rutherford, Maury, Hickman and Hamilton Counties in Tennessee. Its primary deposit products are checking, savings, and term certificate accounts, and its primary lending products are commercial and residential construction loans, commercial loans, installment loans and lines secured by home equity. Substantially all loans are secured by specific items of collateral including commercial and residential real estate, business assets, and consumer assets.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to 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, 2018.

The consolidated financial statements as of and for the periods presented include the accounts of Reliant Bancorp Inc., Reliant Bank, Community First TRUPS Holding Company, which is wholly owned by Reliant Bancorp Inc., (“TRUPS”), Reliant Investment Holdings, LLC ("Holdings") of which is 100% wholly owned by Reliant Bank ("Bank"), and Reliant Mortgage Ventures, LLC ("RMV"), of which the Bank controls 51% of the governance rights. Reliant Bancorp Inc., Reliant Bank, TRUPS, Holdings and RMV, are collectively referred to herein as the “Company”. As described in the notes to our annual consolidated financial statements, all significant inter-company balances and transactions have been eliminated in consolidation. As described in Note 12, Reliant Bancorp, Inc. and Community First, Inc. merged effective January 1, 2018. 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.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Use of Estimates (Continued)

The consolidated financial statements as of March 31, 2019, and for the three months ended March 31, 2019 and 2018, 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 are, in the opinion of management, 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 months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

Reclassifications

Certain reclassifications were made to the March 31, 2018 financial statement presentation in order to conform to the March 31, 2019 financial statement presentation. Total stockholders' equity and net income are unchanged due to these reclassifications.

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 127 and 242 securities in an unrealized loss position as of March 31, 2019 and December 31, 2018, respectively.

Risk characteristics relevant to each portfolio segment are as follows:

Commercial,industrialand 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.

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED)

Multi-family and commercial real estate: Multi-family and commercial real estate and multi-family 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 securing 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 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 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.

1-4family residential real estate: Residential real estate loans 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 residential property values impact the depth of potential losses in this portfolio segment.

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED)

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 residential property 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. 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. 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 March 31, 2019 and December 31, 2018:

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED)

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. Borrower 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.

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES (CONTINUED)

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.

Fair Values of Assets and Liabilities

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;

•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.

NOTE 5 - FAIR VALUES OF ASSETS AND LIABILITIES (CONTINUED)

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 impaired loans 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.

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.

NOTE 5 - FAIR VALUES OF ASSETS AND LIABILITIES (CONTINUED)

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 March 31, 2019 and December 31, 2018:

(1) The fair value is generally determined through independent appraisals of the underlying collateral, which may include Level 3 inputs that are not identifiable, or by using the discounted cash flow method if the loan is not collateral dependent. Estimated cash flows change and appraised values of the assets or collateral underlying the loans will be sensitive to changes.

NOTE 5 - FAIR VALUES OF ASSETS AND LIABILITIES (CONTINUED)

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.

Stock Option Plan

In 2006, the Board of Directors and shareholders of the Bank approved the Commerce Union Bank Stock Option Plan (the “Plan”). The Plan provides for the granting of stock options, and authorizes the issuance of common stock upon the exercise of such options, for up to 625,000 shares of common stock to employees and organizers of the Company. As part of reorganization, all Commerce Union Bank options were replaced with Commerce Union Bancshares, Inc. options with no change in terms. On March 10, 2015, the shareholders of the Company approved the Commerce Union Bancshares, Inc. Amended and Restated Stock Option Plan that permits the grant of awards of up to 1,250,000 shares of the Company

common stock in the form of stock options. As part of the merger with Reliant Bank, all outstanding stock options of Reliant Bank were converted to stock options of Commerce Union Bancshares, Inc. under this plan.

Under the Stock Option 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 ten 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 the common stock on the grant

date.

Regulatory Capital Requirements

3 Months Ended

Mar. 31, 2019

Banking and Thrift [Abstract]

REGULATORY CAPITAL REQUIREMENTS

REGULATORY CAPITAL REQUIREMENTS

The Company and the Bank are subject to regulatory capital requirements administered by the federal and state banking agencies. 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 March 31, 2019, the Company and the Bank meet all capital adequacy requirements to which they are subject.

Prompt corrective action regulations provide five 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 March 31, 2019 and December 31, 2018, 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 FDIC approved final rules that substantially amend the regulatory risk-based capital rules applicable to the Company 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 Act.

Under these rules, the leverage and risk-based capital ratios of bank holding companies 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.

NOTE 7 - REGULATORY CAPITAL REQUIREMENTS (CONTINUED)

Basel III establishes a “capital conservation buffer” of 2.5% which began phasing in on January 1, 2016, at a rate of 0.625% per year. The buffer became fully phased in on January 1, 2019. 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.

Actual and required capital amounts and ratios are presented below as of March 31, 2019 and December 31, 2018.

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 underwritten to participating banks or other investor group standards.

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.

NOTE 10 - DERIVATIVES (CONTINUED)

Interest Rate Swaps Designated as Cash Flow Hedges

Interest rate swaps with notional amounts totaling $60,000 as of March 31, 2019 , were designated as cash flow hedges of certain certificates of deposits 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 March 31, 2019, is as follows:

Notional amounts	$	60,000
Weighted average pay rates	3.338		%
Weighted average receive rates	3.060		%
Weighted average maturity	4.22 years
Unrealized losses	$	1,790

INCOME TAXES

Income tax expense for the three months ended March 31, 2019 and 2018 was $372 and $797. The decline is attributable to; a lower income before tax level, an increased level of tax-exempt income in 2019, increased utilization of state tax credit lending programs, and there were no non-deductible merger expenses in 2019. The effective tax rate for the three months ended March 31, 2019 and 2018 was 14% and 20%, respectively.

Accounting Changes and Error Corrections [Abstract]

RECENT ACCOUNTING PRONOUNCEMENTS

RECENT 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 our 2018 Form 10-K for additional information related to previously issued accounting standards updates.

ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” implements a common revenue standard that clarifies the principles for recognizing revenue. The principle element of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 was originally going to be effective for the Company on January 1, 2018; however, the FASB recently issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date" which deferred the effective date of ASU 2014-09 by one year to January 1, 2019. Revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. The adoption of this standard did not have a significant impact on the Company.

ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment,

(iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to

estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance

sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (viii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. ASU 2016-01 became effective for us on January 1, 2019 and did not have a significant impact on our financial statements.

ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 will require 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 will be effective for us on January 1, 2020 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements. We estimate that the effect of implementing this pronouncement will result in right to use assets of $13,804 and a corresponding liability, using the remaining contractual lease periods. We also estimate the impact on regulatory capital to be a reduction of eight basis points to the Tier 1 leverage capital ratio. Management is presently evaluating the planned renewals of existing leases. If management determines to utilize the renewals of leases then the right to use assets and corresponding liability will increase.

NOTE 13 - RECENT ACCOUNTING PRONOUNCEMENTS (CONTINUED)

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 will be effective on January 1, 2021. We are currently evaluating the potential impact of ASU 2016-13 on our 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. We are also in the process of implementing a third-party vendor solution to assist us in the application of the ASU 2016-13. The adoption of the 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. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our 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 consolidated financial statements.

ASU 2018-13, “Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this update remove disclosures that no longer are considered cost beneficial, modify/clarify the specific requirements of certain disclosures, and add disclosure requirements identified as relevant. ASU 2018-13 will be effective for the Company on January 1, 2021, with early adoption permitted, and is not expected to have a significant impact on our financial statements.

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to 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, 2018.

The consolidated financial statements as of and for the periods presented include the accounts of Reliant Bancorp Inc., Reliant Bank, Community First TRUPS Holding Company, which is wholly owned by Reliant Bancorp Inc., (“TRUPS”), Reliant Investment Holdings, LLC ("Holdings") of which is 100% wholly owned by Reliant Bank ("Bank"), and Reliant Mortgage Ventures, LLC ("RMV"), of which the Bank controls 51% of the governance rights. Reliant Bancorp Inc., Reliant Bank, TRUPS, Holdings and RMV, are collectively referred to herein as the “Company”. As described in the notes to our annual consolidated financial statements, all significant inter-company balances and transactions have been eliminated in consolidation. As described in Note 12, Reliant Bancorp, Inc. and Community First, Inc. merged effective January 1, 2018. 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.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Use of Estimates (Continued)

The consolidated financial statements as of March 31, 2019, and for the three months ended March 31, 2019 and 2018, 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 are, in the opinion of management, 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 months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

Reclassifications

Reclassifications

Certain reclassifications were made to the March 31, 2018 financial statement presentation in order to conform to the March 31, 2019 financial statement presentation. Total stockholders' equity and net income are unchanged due to these reclassifications.

Level 3 input information for Assets Measured at Fair Value

The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which we have utilized Level 3 inputs to determine fair value at March 31, 2019 and December 31, 2018:

	Valuation Techniques (1)	Significant Unobservable Inputs	Range (Weighted Average)
Impaired loans	Appraisal	Estimated costs to sell	10%
Other real estate owned	Appraisal	Estimated costs to sell	10%

(1) The fair value is generally determined through independent appraisals of the underlying collateral, which may include Level 3 inputs that are not identifiable, or by using the discounted cash flow method if the loan is not collateral dependent. Estimated cash flows change and appraised values of the assets or collateral underlying the loans will be sensitive to changes.
