FORWARD-LOOKING STATEMENTS

All statements, other than statements of historical fact, included in this report, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. The words "expect," "anticipate," "intend," "may," "should," "plan," "believe," "seek," "estimate" and similar expressions are intended to identify such forward-looking statements, but other statements not based on historical information may also be considered forward-looking statements. These forward-looking statements are subject to known and unknown risks, uncertainties and other factors that could cause the actual results to differ materially from the statements, including, but not limited to: (i) deterioration in the financial condition of borrowers of Pinnacle Bank and its subsidiaries or BHG resulting in significant increases in loan losses and provisions for those losses and, in the case of BHG, substitutions; (ii) the effects of new outbreaks of COVID-19, including actions taken by governmental officials to curb its spread, and the resulting impact on general economic and financial market conditions and on Pinnacle Financial's and its customers' business, results of operations, asset quality and financial condition; (iii) the speed with which the COVID-19 vaccines can be widely distributed, decisions of governmental agencies to pause the use of one or more vaccines, those vaccines' efficacy against the virus, including new variants and public acceptance of the vaccines; (iv) the failure of announced or anticipated stimulus programs to be timely approved, or approved at all, or the failure of such programs to provide sufficient relief when approved, and the resulting impact on the economy and our customers and their businesses; (v) the inability of Pinnacle Financial, or entities in which it has significant investments, like BHG, to maintain the long-term historical growth rate of its, or such entities', loan portfolio; (vi) changes in loan underwriting, credit review or loss reserve policies associated with economic conditions, examination conclusions, or regulatory developments; (vii) effectiveness of Pinnacle Financial's asset management activities in improving, resolving or liquidating lower-quality assets; (viii) the impact of competition with other financial institutions, including pricing pressures and the resulting impact on Pinnacle Financial’s results, including as a result of compression to net interest margin; (ix) adverse conditions in the national or local economies including in Pinnacle Financial's markets throughout Tennessee, North Carolina, South Carolina, Georgia, Alabama and Virginia, particularly in commercial and residential real estate markets; (x) fluctuations or differences in interest rates on loans or deposits from those that Pinnacle Financial is modeling or anticipating, including as a result of Pinnacle Bank's inability to better match deposit rates with the changes in the short-term rate environment, or that affect the yield curve; (xi) the results of regulatory examinations; (xii) Pinnacle Financial's ability to identify potential candidates for, consummate, and achieve synergies from, potential future acquisitions; (xiii) difficulties and delays in integrating acquired businesses or fully realizing costs savings and other benefits from acquisitions; (xiv) BHG's ability to profitably grow its business and successfully execute on its business plans; (xv) risks of expansion into new geographic or product markets; (xvi) the ability to grow and retain low-cost core deposits and retain large, uninsured deposits, including during times when Pinnacle Bank is seeking to lower rates it pays on deposits; (xvii) any matter that would cause Pinnacle Financial to conclude that there was impairment of any asset, including goodwill or other intangible assets; (xviii) the ineffectiveness of Pinnacle Bank's hedging strategies, or the unexpected counterparty failure or hedge failure of the underlying hedges; (xix) reduced ability to attract additional financial advisors (or failure of such advisors to cause their clients to switch to Pinnacle Bank), to retain financial advisors (including as a result of the competitive environment for associates) or otherwise to attract customers from other financial institutions; (xx) deterioration in the valuation of other real estate owned and increased expenses associated therewith; (xxi) inability to comply with regulatory capital requirements, including those resulting from changes to capital calculation methodologies, required capital maintenance levels or regulatory requests or directives, particularly if Pinnacle Bank's level of applicable commercial real estate loans were to exceed percentage levels of total capital in guidelines recommended by its regulators; (xxii) approval of the declaration of any dividend by Pinnacle Financial's board of directors; (xxiii) the vulnerability of Pinnacle Bank's network and online banking portals, and the systems of parties with whom Pinnacle Bank contracts, to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and other security breaches; (xxiv) the possibility of increased compliance and operational costs as a result of increased regulatory oversight (including by the Consumer Financial Protection Bureau), including oversight of companies in which Pinnacle Financial or Pinnacle Bank have significant investments, like BHG, and the development of additional banking products for Pinnacle Bank's corporate and consumer clients; (xxv) the risks associated with Pinnacle Financial and Pinnacle Bank being a minority investor in BHG, including the risk that the owners of a majority of the equity interests in BHG decide to sell the company or all or a portion of their ownership interests in BHG (triggering a similar sale by Pinnacle Financial and Pinnacle Bank) if not prohibited from doing so by Pinnacle Financial or Pinnacle Bank; (xxvi) the possibility of increased personal or corporate tax rates and the resulting reduction in our and our customers' businesses as a result of any such increases; (xxvii) changes in state and federal legislation, regulations or policies applicable to banks and other financial service providers, like BHG, including regulatory or legislative developments; (xxviii) the availability of and access to capital; (xxiv) adverse results (including costs, fines, reputational harm, inability to obtain necessary approvals and/or other negative effects) from current or future litigation, regulatory examinations or other legal and/or regulatory actions, including as a result of Pinnacle Bank's participation in and execution of government programs related to the COVID-19 pandemic; and (xxx) general competitive, economic, political and market conditions. Additional factors which could affect the forward-looking statements can be found in Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2020, and subsequently filed Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC and available on the SEC's website at http://www.sec.gov. Pinnacle Financial disclaims any obligation to update or revise any forward-looking statements contained in this report, which speak only as of the date hereof, whether as a result of new information, future events or otherwise.

Note 1. Summary of Significant Accounting Policies

Nature of Business — Pinnacle Financial Partners, Inc. (Pinnacle Financial) is a financial holding company whose primary business is conducted by its wholly-owned subsidiary, Pinnacle Bank. Pinnacle Bank is a commercial bank headquartered in Nashville, Tennessee. Pinnacle Financial completed its acquisitions of CapitalMark Bank & Trust (CapitalMark), Magna Bank (Magna), Avenue Financial Holdings, Inc. (Avenue), BNC Bancorp (BNC) and Advocate Capital, Inc. (Advocate Capital) on July 31, 2015, September 1, 2015, July 1, 2016, June 16, 2017 and July 2, 2019, respectively. Pinnacle Financial and Pinnacle Bank also collectively hold a 49% interest in Bankers Healthcare Group, LLC (BHG), a company that primarily serves as a full-service commercial loan provider to healthcare and other professional practices. Pinnacle Bank provides a full range of banking services, including investment, mortgage, insurance, and comprehensive wealth management services, in its 14 primarily urban markets across the Southeast.

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. generally accepted accounting principles (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 the consolidated financial statements and related notes appearing in Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2020 (2020 10-K).

These consolidated financial statements include the accounts of Pinnacle Financial and its wholly-owned subsidiaries. Certain statutory trust affiliates of Pinnacle Financial, as noted in Note 11. Other Borrowings are included in these consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminated in consolidation.

Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date 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 include the determination of the allowance for credit losses and determination of any impairment of goodwill or intangible assets. It is reasonably possible Pinnacle Financial's estimate of the allowance for credit losses and determination of impairment of goodwill or intangible assets could change as a result of the continued impact of the COVID-19 pandemic on the economy. The resulting change in these estimates could be material to Pinnacle Financial's consolidated financial statements. There have been no significant changes to Pinnacle Financial's significant accounting policies as disclosed in the 2020 10-K.

Income Per Common Share — Basic net income per common share (EPS) is computed by dividing net income available to common shareholders by the weighted average common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The difference between basic and diluted weighted average common shares outstanding is attributable to common stock options, restricted share awards, and restricted share unit awards. The dilutive effect of outstanding options, restricted share awards, and restricted share unit awards is reflected in diluted EPS by application of the treasury stock method.

The following is a summary of the basic and diluted net income per common share calculations for the three and six months ended June 30, 2021 and 2020 (in thousands, except per share data):

Recently Adopted Accounting Pronouncements — In January 2020, the FASB issued Accounting Standards Update 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. These amendments, among other things, clarify that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, Investments-Equity Method and Joint Ventures, for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments also clarify that when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. An entity should apply ASU 2020-01 prospectively at the beginning of the interim period that includes the adoption date. The amendments became effective for Pinnacle Financial on January 1, 2021 and had no impact on Pinnacle Financial's consolidated financial statements.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes to simplify various aspects of the current guidance to promote consistent application of the standard among reporting entities by moving certain exceptions to the general principles. The amendments are effective for fiscal years beginning after December 15, 2020. The amendments became effective for Pinnacle Financial on January 1, 2021 and had no impact on Pinnacle Financial's consolidated financial statements.

In March 2020, the FASB issued Accounting Standards Update 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and has issued subsequent amendments thereto, which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. Pinnacle Financial is implementing a transition plan to identify and modify its loans and other financial instruments, including certain indebtedness, with attributes that are either directly or indirectly influenced by LIBOR. Pinnacle Financial is assessing ASU 2020-04 and its impact on the transition away from LIBOR for its loans and other financial instruments.

During the quarters ended March 31, 2020 and September 30, 2018, Pinnacle Financial transferred, at fair value, $873.6 million and $179.8 million, respectively, of municipal securities from the available-for-sale portfolio to the held-to-maturity portfolio. The related net unrealized after tax gains of $69.0 million and net unrealized after tax losses of $2.2 million, respectively, remained in accumulated other comprehensive income (loss) and are being amortized over the remaining life of the securities, offsetting the related amortization of discount or premium on the transferred securities. No gains or losses were recognized at the time of the transfer. At June 30, 2021, approximately $676.5 million of securities within Pinnacle Financial's investment portfolio were pledged to secure either public funds and other deposits or securities sold under agreements to repurchase. At June 30, 2021, repurchase agreements comprised of secured borrowings totaled $177.7 million and were secured by $177.7 million of pledged U.S. government agency securities, municipal securities, asset-backed securities, and corporate debentures. As the fair value of securities pledged to secure repurchase agreements may decline, Pinnacle Financial regularly evaluates its need to pledge additional securities to remain adequately secured.

The applicable dates for determining when securities were in an unrealized loss position were June 30, 2021 and December 31, 2020. As such, it is possible that a security had a market value less than its amortized cost on other days during the past twelve-month periods ended June 30, 2021 and December 31, 2020, but is not in the "Investments with an Unrealized Loss of less than 12 months" category above.

As shown in the tables above, including both available-for-sale and held-to-maturity investment securities, at June 30, 2021, Pinnacle Financial had approximately $14.0 million in unrealized losses on approximately $1.0 billion of securities. The unrealized losses associated with $873.6 million and $179.8 million of municipal securities transferred from the available-for-sale portfolio to the held-to-maturity portfolio during the quarters ended March 31, 2020 and September 30, 2018, respectively, represent unrealized losses since the date of purchase, independent of the impact associated with changes in the cost basis upon transfer between portfolios. For any securities classified as available-for-sale that are in an unrealized loss position at the balance sheet date, Pinnacle Financial assesses whether or not it intends to sell the security, or more likely than not will be required to sell the security, before recovery of its amortized cost basis which would require a write-down to fair value through net income. Because Pinnacle Financial currently does not intend to sell those securities that have an unrealized loss at June 30, 2021, and it is not more-likely-than-not that Pinnacle

Table of Contents

Financial will be required to sell the securities before recovery of their amortized cost bases, which may be maturity, Pinnacle Financial has determined that no write-down is necessary. In addition, Pinnacle Financial evaluates whether any portion of the decline in fair value is the result of credit deterioration, which would require the recognition of an allowance for credit losses. Such evaluations consider the extent to which the amortized cost of the security exceeds its fair value, changes in credit ratings and any other known adverse conditions related to the specific security. The unrealized losses associated with securities at June 30, 2021 are driven by changes in interest rates and are not due to the credit quality of the securities, and accordingly, no allowance for credit losses is considered necessary related to available-for-sale securities at June 30, 2021. These securities will continue to be monitored as a part of Pinnacle Financial's ongoing evaluation of credit quality. Management evaluates the financial performance of the issuers on a quarterly basis to determine if it is probable that the issuers can make all contractual principal and interest payments.

The allowance for credit losses on held-to-maturity securities is measured on a collective basis by major security type. At June 30, 2021, Pinnacle Financial's held-to-maturity securities consist entirely of municipal securities. The estimates of expected credit losses are based on historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. A reasonable and supportable period of 18 months and reversion period of 12 months was utilized to estimate credit losses on held-to-maturity municipal securities at each of June 30, 2021 and 2020. At June 30, 2021 and December 31, 2020, the estimated allowance for credit losses on these securities was $198,000 and $191,000, respectively, with the change driven largely by changes in macroeconomic projections.

Pinnacle Financial utilizes bond credit ratings assigned by third party ratings agencies to monitor the credit quality of debt securities held-to-maturity. At June 30, 2021, all debt securities classified as held-to-maturity were rated A or higher by the ratings agencies. Updated credit ratings are obtained as they become available from the ratings agencies.

Periodically, available-for-sale securities may be sold or the composition of the portfolio realigned to improve yields, quality or marketability, or to implement changes in investment or asset/liability strategy, including maintaining collateral requirements and raising funds for liquidity purposes or preparing for anticipated changes in market interest rates. Additionally, if an available-for-sale security loses its investment grade or tax-exempt status, the underlying credit support is terminated or collection otherwise becomes uncertain based on factors known to management, Pinnacle Financial will consider selling the security, but will review each security on a case-by-case basis as these factors become known. During the six months ended June 30, 2021, $2.2 million of available-for-sale securities were sold and $270,000 related to net gains on sales of available-for-sale securities were reclassified from accumulated other comprehensive income into net income.

Pinnacle Financial has entered into various fair value hedging transactions to mitigate the impact of changing interest rates on the fair values of available for sale securities. See Note 8. Derivative Instruments for disclosure of the gains and losses recognized on derivative instruments and the cumulative fair value hedging adjustments to the carrying amount of the hedged securities.

Note 4. Loans and Allowance for Credit Losses

For financial reporting purposes, Pinnacle Financial classifies its loan portfolio based on the underlying collateral utilized to secure each loan. This classification is consistent with those utilized in the Quarterly Report of Condition and Income filed by Pinnacle Bank with the Federal Deposit Insurance Corporation (FDIC).

Pinnacle Financial uses the following loan categories for presentation of loan balances and the related allowance for credit losses on loans:

•Owner occupied commercial real estate mortgage loans - Owner occupied commercial real estate mortgage loans are secured by commercial office buildings, industrial buildings, warehouses or retail buildings where the owner of the building occupies the property. For such loans, repayment is largely dependent upon the operation of the borrower's business.

•Non-owner occupied commercial real estate loans - These loans represent investment real estate loans secured by office buildings, industrial buildings, warehouses, retail buildings, and multifamily residential housing. Repayment is primarily dependent on lease income generated from the underlying collateral.

•Consumer real estate mortgage loans - Consumer real estate mortgage consists primarily of loans secured by 1-4 family residential properties, including home equity lines of credit. Repayment is primarily dependent on the personal cash flow of the borrower.

•Construction and land development loans - Construction and land development loans include loans where the repayment is dependent on the successful completion and eventual sale, refinance or operation of the related real estate project. Construction and land development loans include 1-4 family construction projects and commercial construction endeavors such as warehouses, apartments, office and retail space and land acquisition and development.

•Commercial and industrial loans - Commercial and industrial loans include loans to business enterprises issued for commercial, industrial and/or other professional purposes. These loans are generally secured by equipment, inventory, and accounts receivable of the borrower and repayment is primarily dependent on business cash flows. Loans totaling $1.4 billion and $1.8 billion granted under the Paycheck Protection Program are included in this category as of June 30, 2021, and December 31, 2020, respectively.

•Consumer and other loans - Consumer and other loans include all loans issued to individuals not included in the consumer real estate mortgage classification. Examples of consumer and other loans are automobile loans, consumer credit cards and loans to finance education, among others. Many consumer loans are unsecured. Repayment is primarily dependent on the personal cash flow of the borrower.

Loans at June 30, 2021 and December 31, 2020 were as follows:

	June 30, 2021		December 31, 2020
Commercial real estate:

Commercial loans receive risk ratings assigned by a financial advisor subject to validation by Pinnacle Financial's independent loan review department. Risk ratings are categorized as pass, special mention, substandard, substandard-nonaccrual or doubtful-nonaccrual. Pass rated loans include multiple ratings categories representing varying degrees of risk attributes lesser than those of the other defined risk categories further described below. Pinnacle Financial believes its categories follow those used by Pinnacle Bank's primary regulators. At June 30, 2021, approximately 76.5% of Pinnacle Financial's loan portfolio was analyzed as a commercial loan type with a specifically assigned risk rating. Consumer loans and small business loans are generally not assigned an individual risk rating but are evaluated as either accrual or nonaccrual based on the performance of the individual loans. However, certain consumer real estate-mortgage loans and certain consumer and other loans receive a specific risk rating due to the loan proceeds being used for commercial purposes even though the collateral may be of a consumer loan nature. Consumer loans that have been placed on nonaccrual but have not otherwise been assigned a risk rating are believed by management to share risk characteristics with loans rated substandard-nonaccrual and have been presented as such in Pinnacle Financial's risk rating disclosures.

Risk ratings are subject to continual review by a financial advisor and a senior credit officer. At least annually, Pinnacle Financial's credit procedures require every risk rated loan of $1.0 million or more be subject to a formal credit risk review process. Each loan's risk rating is also subject to review by Pinnacle Financial's independent loan review department, which reviews a substantial portion of Pinnacle Financial's risk rated portfolio annually. Included in the coverage are independent reviews of loans in targeted higher-risk portfolio segments such as certain commercial and industrial loans, land loans and/or loan types in certain geographies. Substantial credit risk review procedures have been performed to assess the impacts of the COVID-19 pandemic on the loan portfolio, and the results of these procedures are reflected in Pinnacle Financial's risk rating disclosures as of June 30, 2021.

Following are the definitions of the risk rating categories used by Pinnacle Financial. Pass rated loans include all credits other than those included within these categories:

•Special mention loans have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in Pinnacle Financial's credit position at some future date.

•Substandard loans are inadequately protected by the current net worth and financial capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize collection of the debt. Substandard loans are characterized by the distinct possibility that Pinnacle Financial could sustain some loss if the deficiencies are not corrected.

•Substandard-nonaccrual loans are substandard loans that have been placed on nonaccrual status.

•Doubtful-nonaccrual loans have all the characteristics of substandard-nonaccrual loans 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.

(1) Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have doubts about the borrower's ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators for loans classified as substandard, excluding troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $169.3 million at June 30, 2021, compared to $173.5 million at December 31, 2020.

The adequacy of the allowance for credit losses is reviewed by Pinnacle Financial's management on a quarterly basis. This assessment includes procedures to estimate the allowance and test the adequacy and appropriateness of the resulting balance. The level of the allowance is based upon management's evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay the loan (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. The level of the allowance for credit losses maintained by management is believed adequate to absorb all expected future losses inherent in the loan portfolio at the balance sheet date. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off.

Pinnacle Financial adopted ASU 2016-13 on January 1, 2020, which introduced the CECL methodology for estimating all expected losses over the life of a financial asset. Under the CECL methodology the allowance for credit losses is measured on a collective basis for pools of loans with similar risk characteristics, and for loans that do not share similar risk characteristics with the collectively evaluated pools, evaluations are performed on an individual basis. Upon adoption of ASU 2016-13 in 2020, the opening balance of the allowance for credit losses was increased by $38.1 million through retained earnings.

For commercial real estate, consumer real estate, construction and land development, and commercial and industrial loans, Pinnacle Financial primarily utilizes a probability of default and loss given default modeling approach. These models utilize historical correlations between default experience and certain macroeconomic factors as determined through a statistical regression analysis. All loan segments modeled using this approach consider changes in the national unemployment rate. In addition to the national unemployment rate, GDP and the three month treasury rate are considered for owner occupied commercial real estate, the commercial real estate price index and the five year treasury rate are considered for construction loans, and the three month treasury rate is considered for commercial and industrial loans. For the consumer and other loan segment, a non-statistical approach based on historical charge off rates is utilized.

Losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable period losses are reverted to long term historical averages. The reasonable and supportable period and reversion period are re-evaluated each quarter by Pinnacle Financial and are dependent on the current economic environment among other factors. At June 30, 2021 and December 31, 2020, a reasonable and supportable period of 18 months was utilized for all loan segments, followed by a 12 month straight line reversion to long term averages.

The estimated loan losses for all loan segments are adjusted for changes in qualitative factors not inherently considered in the quantitative analyses. These adjustments are based upon quarterly trend assessments in portfolio concentrations, policy exceptions, associate retention, independent loan review results, collateral considerations, risk ratings, competition and peer group credit quality trends. The qualitative allowance allocation, as determined by the processes noted above, is increased or decreased for each loan segment based on the assessment of these various qualitative factors.

Loans that do not share similar risk characteristics with the collectively evaluated pools are evaluated on an individual basis and are excluded from the collectively evaluated pools. Individual evaluations are generally performed for loans greater than $1.0 million which have experienced significant credit deterioration. Such loans are evaluated for credit losses based on either discounted cash flows or the fair value of collateral.

The following table presents the amortized cost basis of collateral dependent loans, which are individually evaluated to determine expected credit losses, as of June 30, 2021 and December 31, 2020 (in thousands):

Pinnacle Financial's policy is the accrual of interest income will be discontinued when (1) there is a significant deterioration in the financial condition of the borrower and full repayment of principal and interest is not expected or (2) the principal or interest is more than 90 days past due, unless the loan is both well secured and in the process of collection. As such, at the date loans are placed on nonaccrual status, Pinnacle Financial reverses all previously accrued interest income against current year earnings. Pinnacle Financial's policy is once a loan is placed on nonaccrual status each subsequent payment is reviewed on a case-by-case basis to determine if the payment should be applied to interest or principal pursuant to regulatory guidelines. Pinnacle Financial recognized no interest income from cash payments received on nonaccrual loans during the three and six months ended June 30, 2021 and 2020, respectively. Had these loans been on accruing status, an additional $776,000 and $1.1 million of interest income would have been recognized for the three and six months ended June 30, 2021 compared to an additional $854,000 and $1.6 million for the three and six months ended June 30, 2020, respectively. Approximately $39.5 million and $51.7 million of nonaccrual loans were performing pursuant to their contractual terms as of June 30, 2021 and December 31, 2020, respectively.

At June 30, 2021 and December 31, 2020, there were $2.4 million and $2.5 million, respectively, of troubled debt restructurings that were performing as of their restructure date and which were accruing interest. Troubled commercial loans are restructured by specialists within Pinnacle Bank's Special Assets Group, and all restructurings are approved by committees and/or credit officers separate and apart from the normal loan approval process. These specialists are charged with reducing Pinnacle Financial's overall risk and exposure to loss in the event of a restructuring by obtaining some or all of the following: improved documentation, additional guaranties, increase in curtailments, reduction in collateral release terms, additional collateral or other similar strategies.

There were no troubled debt restructurings made during the six months ended June 30, 2021. During the six months ended June 30, 2021 and 2020, there were no troubled debt restructurings that subsequently defaulted within twelve months of the restructuring. The following table outlines the amount of each loan category where troubled debt restructurings were made during the six months ended June 30, 2020 (in thousands):

	June 30, 2020

Pinnacle Financial analyzes its commercial loan portfolio to determine if a concentration of credit risk exists to any industries. Pinnacle Financial utilizes broadly accepted industry classification systems in order to classify borrowers into various industry classifications. Pinnacle Financial has a credit exposure (loans outstanding plus unfunded lines of credit) exceeding 25% of Pinnacle Bank's total risk-based capital to borrowers in the following industries at June 30, 2021 with the comparative exposures for December 31, 2020 (in thousands):

	June 30, 2021
	Outstanding Principal Balances		Unfunded Commitments		Total exposure		Total Exposure at December 31, 2020
Lessors of nonresidential buildings	$	3,587,877	$	1,228,232	$	4,816,109	$	4,442,712
Lessors of residential buildings	1,376,546		887,899		2,264,445		2,126,246
Hotels (except Casino Hotels) and Motels	979,770		65,699		1,045,469		1,039,259
New Housing For-Sale Builders	493,082		814,372		1,307,454		1,124,302

Pinnacle Financial monitors two ratios regarding construction and commercial real estate lending as part of its concentration management processes. Both ratios are calculated by dividing certain types of loan balances for each of the two categories by Pinnacle Bank’s total risk-based capital. At June 30, 2021 and December 31, 2020, Pinnacle Bank’s construction and land development loans as a percentage of total risk-based capital were 80.1% and 89.0%, respectively. Non-owner occupied commercial real estate and multifamily loans (including construction and land development loans) as a percentage of total risk-based capital were 248.8% and 264.0% as of June 30, 2021 and December 31, 2020, respectively. Banking regulations have established guidelines for the construction ratio of less than 100% of total risk-based capital and for the non-owner occupied ratio of less than 300% of total risk-based capital. When a bank’s ratios are in excess of one or both of these guidelines, banking regulations generally require an increased level of monitoring in these lending areas by bank management. At June 30, 2021, Pinnacle Bank was within the 100% and 300% guidelines and has established what it believes to be appropriate controls to monitor its lending in these areas as it aims to keep the level of these loans below the 100% and 300% thresholds.

Table of Contents

At June 30, 2021, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $8.8 million to current directors, executive officers, and their related interests, of which $5.4 million had been drawn upon. At December 31, 2020, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $10.7 million to directors, executive officers, and their related interests, of which approximately $6.8 million had been drawn upon. All loans to directors, executive officers, and their related interests were performing in accordance with contractual terms at June 30, 2021 and December 31, 2020.

At June 30, 2021, Pinnacle Financial had approximately $25.8 million in commercial loans held for sale compared to $31.2 million at December 31, 2020, which primarily included commercial real estate and apartment loans originated for sale to a third-party as part of a multi-family loan program. Such loans are closed under a pass-through commitment structure wherein Pinnacle Bank's loan commitment to the borrower is the same as the third party's take-out commitment to Pinnacle Bank and the third party purchase typically occurs within thirty days of Pinnacle Bank closing with the borrowers.

Residential Lending

At June 30, 2021, Pinnacle Financial had approximately $37.3 million of mortgage loans held-for-sale compared to approximately $67.8 million at December 31, 2020. Total loan volumes sold during the six months ended June 30, 2021 were approximately $941.3 million compared to approximately $837.4 million for the six months ended June 30, 2020. During the three and six months ended June 30, 2021, Pinnacle Financial recognized $6.7 million and $20.4 million, respectively, in gains on the sale of these loans, net of commissions paid, compared to $19.6 million and $28.2 million, respectively, during the three and six months ended June 30, 2020.

These mortgage loans held-for-sale are originated internally and are primarily to borrowers in Pinnacle Bank's geographic markets. These sales are typically on a mandatory basis to investors that follow conventional government sponsored entities (GSE) and the Department of Housing and Urban Development/U.S. Department of Veterans Affairs (HUD/VA) guidelines.

Each purchaser of a mortgage loan held-for-sale has specific guidelines and criteria for sellers of loans and the risk of credit loss with regard to the principal amount of the loans sold is generally transferred to the purchasers upon sale. While the loans are sold without recourse, the purchase agreements require Pinnacle Bank to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that the loans sold were in breach of these representations or warranties, Pinnacle Bank has obligations to either repurchase the loan for the unpaid principal balance and related investor fees or make the purchaser whole for the economic benefits of the loan. To date, Pinnacle Bank's liability pursuant to the terms of these representations and warranties has been insignificant to Pinnacle Bank.

Note 5. Income Taxes

ASC 740, Income Taxes, defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authority. This section also provides guidance on the derecognition, measurement and classification of income tax uncertainties, along with any related interest and penalties, and includes guidance concerning accounting for income tax uncertainties in interim periods.

The unrecognized tax benefit related to uncertain tax positions related to state income tax filings was $9.7 million at June 30, 2021 and December 31, 2020, respectively. No change was recorded to the unrecognized tax benefit related to uncertain tax positions in each of the three and six month periods ended June 30, 2021 and 2020.

Pinnacle Financial's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. For both the three and six months ended June 30, 2021 and 2020, respectively, there were no interest and penalties recorded in the income statement.

Pinnacle Financial's effective tax rate for the three and six months ended June 30, 2021 was 18.9% and 18.6%, respectively, compared to 15.2% and 9.5%, respectively, for the three and six months ended June 30, 2020. The difference between the effective tax rate and the federal and state income tax statutory rate of 26.14% at June 30, 2021 and 2020 is primarily due to investments in bank qualified municipal securities, tax benefits of Pinnacle Bank's real estate investment trust subsidiary, participation in the Tennessee Community Investment Tax Credit (CITC) program, and tax benefits associated with share-based compensation, bank-owned life insurance and Pinnacle Financial's captive insurance subsidiary, offset in part by the limitation on deductibility of meals and entertainment expense, non-deductible FDIC premiums and non-deductible executive compensation.

Table of Contents

Income tax expense is also impacted by the vesting of equity-based awards and the exercise of employee stock options, which expense or benefit is recorded as a discrete item as a component of total income tax, the amount of which is dependent upon the change in the grant date fair value and the vest date fair value of the underlying award. Accordingly, for the three and six months ended June 30, 2021, we recognized excess tax benefits of $302,000 and $1.9 million, respectively, compared to expense of $272,000 and benefits of $590,000, respectively, for the three and six months ended June 30, 2020. For the six months ended June 30, 2020, income tax expense was also meaningfully impacted by provision for credit losses, including provision for credit losses resulting from the COVID-19 pandemic, which was recorded as a discrete item as a component of total income tax and contributed to a tax benefit of $22.4 million for the six months ended June 30, 2020.

Note 6. Commitments and Contingent Liabilities

In the normal course of business, Pinnacle Financial has entered into off-balance sheet financial instruments which include commitments to extend credit (i.e., including unfunded lines of credit) and standby letters of credit. Commitments to extend credit are usually the result of lines of credit granted to existing borrowers under agreements that the total outstanding indebtedness will not exceed a specific amount during the term of the indebtedness. Typical borrowers are commercial concerns that use lines of credit to supplement their treasury management functions, thus their total outstanding indebtedness may fluctuate during any time period based on the seasonality of their business and the resultant timing of their cash flows. Other typical lines of credit are related to home equity loans granted to consumers. Commitments to extend credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. At June 30, 2021, these commitments amounted to $10.6 billion, of which approximately $1.2 billion related to home equity lines of credit.

Standby letters of credit are generally issued on behalf of an applicant (customer) to a specifically named beneficiary and are the result of a particular business arrangement that exists between the applicant and the beneficiary. Standby letters of credit have fixed expiration dates and are usually for terms of two years or less unless terminated beforehand due to criteria specified in the standby letter of credit. A typical arrangement involves the applicant routinely being indebted to the beneficiary for such items as inventory purchases, insurance, utilities, lease guarantees or other third party commercial transactions. The standby letter of credit would permit the beneficiary to obtain payment from Pinnacle Financial under certain prescribed circumstances. Subsequently, Pinnacle Financial would then seek reimbursement from the applicant pursuant to the terms of the standby letter of credit. At June 30, 2021, these commitments amounted to $243.8 million.

Pinnacle Financial typically follows the same credit policies and underwriting practices when making these commitments as it does for on-balance sheet instruments. Each customer's creditworthiness is typically evaluated on a case-by-case basis, and the amount of collateral obtained, if any, is based on management's credit evaluation of the customer. Collateral held varies but may include cash, real estate and improvements, marketable securities, accounts receivable, inventory, equipment and personal property.

The contractual amounts of these commitments are not reflected in the consolidated financial statements and only amounts drawn upon would be reflected in the future. Since many of the commitments are expected to expire without being drawn upon, the contractual amounts do not necessarily represent future cash requirements. However, should the commitments be drawn upon and should Pinnacle Bank's customers default on their resulting obligation to Pinnacle Bank, the maximum exposure to credit loss, without consideration of collateral, is represented by the contractual amount of those commitments. At June 30, 2021 and December 31, 2020, Pinnacle Financial had accrued $23.2 million for the inherent risks associated with these off-balance sheet commitments.

Various legal claims also arise from time to time in the normal course of business. In the opinion of management, the resolutions of these claims outstanding at June 30, 2021 are not expected to have a material adverse impact on Pinnacle Financial's consolidated financial condition, operating results or cash flows.

Note 7.  Stock Options and Restricted Shares

Pinnacle Financial's Amended and Restated 2018 Omnibus Equity Incentive Plan (the "2018 Plan") permits Pinnacle Financial to reissue outstanding awards that are subsequently forfeited, settled in cash, withheld by Pinnacle Financial to cover withholding taxes or expire unexercised and returned to the 2018 Plan. At June 30, 2021, there were approximately 2.0 million shares available for issuance under the 2018 Plan.

Upon the acquisition of CapitalMark, Pinnacle Financial assumed approximately 858,000 stock options under the CapitalMark Option Plan. No further awards remain available for issuance under the CapitalMark Option Plan. At June 30, 2021, all of the options remaining outstanding under any equity incentive plan of Pinnacle Financial were granted under the CapitalMark Option Plan.

(1)The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of Pinnacle Financial common stock of $64.40 per common share at December 31, 2020 for the 101,769 options that were in-the-money at December 31, 2020.

(2)The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of Pinnacle Financial common stock of $88.29 per common share at June 30, 2021 for the 83,495 options that were in-the-money at June 30, 2021.

Compensation costs related to stock options granted under Pinnacle Financial's equity incentive plans have been fully recognized and all outstanding option awards are fully vested.

Restricted Share Awards

A summary of activity for unvested restricted share awards for the six months ended June 30, 2021 is as follows:

	Number	Grant Date Weighted-Average Cost
Unvested at December 31, 2020	594,669	$	56.97
Shares awarded	200,346
Restrictions lapsed and shares released to associates/directors	(157,734)
Shares forfeited	(24,757)
Unvested at June 30, 2021	612,524	$	62.06

Pinnacle Financial has granted restricted share awards to associates and outside directors with a time-based vesting criteria. Compensation expense associated with time-based vesting restricted share awards is recognized over the time period that the restrictions associated with the awards lapse on a straight-line basis based on the total cost of the award. The following table outlines restricted stock grants that were made, grouped by similar vesting criteria, during the six months ended June 30, 2021. The table reflects the life-to-date activity for these awards:

Grant Year	Group (1)	Vesting Period in years			Shares awarded	Restrictions lapsed and shares released to participants	Shares withheld for taxes by participants	Shares Forfeited by participants (4)	Shares Unvested
Time Based Awards

Outside Director Awards (3)
2021	Outside directors			1	11,830	—	—	—	11,830

(1)Groups include employees (referred to as associates above) and outside directors. When the restricted shares are awarded, a participant receives voting rights and forfeitable dividend rights with respect to the shares, but is not able to transfer the shares until the restrictions have lapsed. Once the restrictions lapse, the participant is taxed on the value of the award and may elect to sell some shares (or have Pinnacle Financial withhold some shares) to pay the applicable income taxes associated with the award. Alternatively, the recipient can pay the withholding taxes in cash. For time-based vesting restricted share awards, dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination. For awards to Pinnacle Financial's directors, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.

(2)The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant.

Restricted Stock Unit Awards

In 2021, Pinnacle Financial granted restricted stock units to its Named Executive Officers (NEOs) and leadership team members with time-based vesting criteria. Compensation expense associated with time-based vesting restricted stock unit awards is recognized over the time period that the restrictions associated with the awards lapse on a straight-line basis based on the total cost of the award. The following table outlines restricted stock unit grants that were made, grouped by similar vesting criteria, during the six months ended June 30, 2021.

Table of Contents

During the six months ended June 30, 2021 and 2020, the restrictions associated with 133,041 and 129,723 performance stock unit awards granted in prior years lapsed, based on the terms of the agreement and approval by Pinnacle Financial's Human Resources and Compensation Committee, and were settled into shares of Pinnacle Financial common stock with 46,332 and 43,996 shares being withheld to pay the taxes associated with the settlement of those shares.

Additionally, during the six months ended June 30, 2021, 199,633 performance stock unit awards granted in prior years were forfeited due to the failure to reach performance targets for the year ended December 31, 2020 as defined in the associated performance stock unit award agreements.

Stock compensation expense related to restricted share awards, restricted stock unit awards and performance stock unit awards for the three and six months ended June 30, 2021 was $5.7 million and $11.1 million, respectively, compared to $4.1 million and $9.6 million, respectively, for the three and six months ended June 30, 2020. As of June 30, 2021, the total compensation cost related to unvested restricted share awards, restricted stock unit awards and performance stock unit awards not yet recognized was $59.9 million. This expense, if the underlying units are earned, is expected to be recognized over a weighted-average period of 1.72 years.

Note 8. Derivative Instruments

Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship and classification as either a cash flow hedge or fair value hedge for those derivatives which are designated as part of a hedging relationship.

Non-hedge derivatives

For derivatives not designated as hedges, the gain or loss is recognized in current period earnings. Pinnacle Financial enters into interest rate swaps (swaps) to facilitate customer transactions and meet their financing needs. Upon entering into these instruments to meet customer needs, Pinnacle Financial enters into offsetting positions in order to minimize the risk to Pinnacle Financial. These swaps qualify as derivatives, but are not designated as hedging instruments. The income statement impact of the offsetting positions is limited to changes in the reserve for counterparty credit risk. A summary of Pinnacle Financial's interest rate swaps to facilitate customers' transactions as of June 30, 2021 and December 31, 2020 is included in the following table (in thousands):

	June 30, 2021				December 31, 2020
	Notional Amount		Estimated Fair Value		Notional Amount		Estimated Fair Value
Interest rate swap agreements:
Assets	$	1,577,735	$	66,074	$	1,565,916	$	101,602
Liabilities	1,577,735		(66,890)		1,565,916		(102,919)
Total	$	3,155,470	$	(816)	$	3,131,832	$	(1,317)

The effects of Pinnacle Financial's interest rate swaps to facilitate customers' transactions on the income statement during the three and six months ended June 30, 2021 and 2020 were as follows (in thousands):

		Amount of Gain (Loss) Recognized in Income
	Location of Loss Recognized in Income	Three Months Ended June 30,				Six Months Ended June 30,

Interest rate swap agreements	Other noninterest income	$	51	$	(794)	$	501	$	(1,137)

Derivatives designated as cash flow hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income (loss), net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. Pinnacle Financial uses forward cash flow hedge relationships in an effort to manage future interest rate exposure. A summary of Pinnacle Financial's cash flow hedge relationships as of June 30, 2021 and December 31, 2020 is as follows (in thousands):

The effects of Pinnacle Financial's cash flow hedge relationships on the statement of comprehensive income (loss) during the three and six months ended June 30, 2021 and 2020 were as follows, net of tax (in thousands):

	Amount of Gain (Loss) Recognized in Other Comprehensive Income (Loss)
	Three Months Ended June 30,				Six Months Ended June 30,

	$	240	$	6,459	$	(15,034)	$	70,228

The cash flow hedges were determined to be highly effective during the periods presented and as a result qualify for hedge accounting treatment. If a hedge was deemed to be ineffective, the amount included in accumulated other comprehensive income (loss) would be reclassified into a line item within the statement of income that impacts operating results. The hedge would no longer be considered effective if a portion of the hedge becomes ineffective, the item hedged is no longer in existence or Pinnacle Financial discontinues hedge accounting. Gains on cash flow hedges totaling $2.7 million and $2.2 million, net of tax, were reclassified from accumulated other comprehensive income (loss) into net income during the three and six months ended June 30, 2021, respectively, compared to gains totaling $123,000 and losses totaling $1.7 million, net of tax, during the three and six months ended June 30, 2020, respectively. During the second quarter of 2021, loan interest rate floors with a notional amount totaling $1.5 billion and unrealized gains totaling $34.3 million, net of tax, were terminated. These unrealized gains are being amortized into income on a straight line basis through November 2024. Approximately $12.5 million in unrealized gains, net of tax, are expected to be reclassified from accumulated other comprehensive income (loss) into net income over the next twelve months related to previously terminated cash flow hedges.

Derivatives designated as fair value hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. Pinnacle Financial utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable available-for-sale securities. The hedging strategy converts the fixed interest rates to variable interest rates based on LIBOR or federal funds rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities.

Note 9. Fair Value of Financial Instruments

FASB ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in U.S. GAAP and expands disclosures about fair value measurements.  The definition of fair value focuses on the exit price, i.e., the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, not the entry price, i.e., the price that would be paid to acquire the asset or received to assume the liability at the measurement date.  The statement emphasizes that fair value is a market-based measurement; not an entity-specific measurement.  Therefore, the fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability.

Valuation Hierarchy

FASB ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

28

Table of Contents

•Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

•Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement.

A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.

Assets

Securities available-for-sale – Where quoted prices are available for identical securities in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government securities and certain other financial products. If quoted market prices are not available, then fair values are estimated by using pricing models that use observable inputs or quoted prices of securities with similar characteristics and are classified within Level 2 of the valuation hierarchy. In certain cases where there is limited activity or less transparency around inputs to the valuation and more complex pricing models or discounted cash flows are used, securities are classified within Level 3 of the valuation hierarchy.

Other investments – Included in other investments are investments recorded at fair value primarily in certain nonpublic investments and funds. The valuation of these nonpublic investments requires management judgment due to the absence of observable quoted market prices, inherent lack of liquidity and the long-term nature of such assets. These investments are valued initially based upon transaction price. The carrying values of other investments are adjusted either upwards or downwards from the transaction price to reflect expected exit values as evidenced by financing and sale transactions with third parties, or when determination of a valuation adjustment is confirmed through ongoing reviews by senior investment managers. A variety of factors are reviewed and monitored to assess positive and negative changes in valuation including, but not limited to, current operating performance and future expectations of the particular investment, industry valuations of comparable public companies and changes in market outlook and the third-party financing environment over time. In determining valuation adjustments resulting from the investment review process, emphasis is placed on current company performance and market conditions. These investments are included in Level 3 of the valuation hierarchy if the entities and funds are not widely traded and the underlying investments are in privately-held and/or start-up companies for which market values are not readily available. Certain investments in funds for which the underlying assets of the fund represent publicly traded investments are included in Level 2 of the valuation hierarchy.

Other assets – Included in other assets are certain assets carried at fair value, including interest rate swap agreements to facilitate customer transactions, interest rate floors designated as cash flow hedges, and interest rate locks associated with the mortgage loan pipeline. The carrying amount of interest rate swap agreements is based on Pinnacle Financial's pricing models that utilize observable market inputs. The fair value of the cash flow hedge agreements is determined by calculating the difference between the discounted fixed rate cash flows and the discounted variable rate cash flows. The fair value of the mortgage loan pipeline is based upon the projected sales price of the underlying loans, taking into account market interest rates and other market factors at the measurement date, net of the projected fallout rate.  Pinnacle Financial reflects these assets within Level 2 of the valuation hierarchy as these assets are valued using similar transactions that occur in the market.

Collateral dependent loans – Collateral dependent loans are measured at the fair value of the collateral securing the loan less estimated selling costs. The fair value of real estate collateral is determined based on real estate appraisals which are generally based on recent sales of comparable properties which are then adjusted for property specific factors. Non-real estate collateral is valued based on various sources, including third party asset valuations and internally determined values based on cost adjusted for depreciation and other judgmentally determined discount factors. Collateral dependent loans are classified within Level 3 of the hierarchy due to the unobservable inputs used in determining their fair value such as collateral values and the borrower's underlying financial condition.

Other real estate owned – Other real estate owned (OREO) represents real estate foreclosed upon by Pinnacle Bank through loan defaults by customers or acquired by deed in lieu of foreclosure. A significant portion of these amounts relate to lots, homes and development projects that are either completed or are in various stages of construction for which Pinnacle Financial believes it has adequate collateral. Upon foreclosure, the property is recorded at the lower of cost or fair value, based on appraised value, less selling costs estimated as of the date acquired with any loss recognized as a charge-off through the allowance for credit losses. Additional OREO losses for subsequent valuation downward adjustments are determined on a specific property basis and are included as a

29

Table of Contents

component of noninterest expense along with holding costs. Any gains or losses realized at the time of disposal are also reflected in noninterest expense, as applicable. OREO is included in Level 3 of the valuation hierarchy due to the lack of observable market inputs into the determination of fair value as appraisal values are property-specific and sensitive to the changes in the overall economic environment.

Liabilities

Other liabilities – Pinnacle Financial has certain liabilities carried at fair value including certain interest rate swap agreements to facilitate customer transactions, interest rate swaps designated as fair value and cash flow hedges, and interest rate locks associated with the funding for its mortgage loan originations. The fair value of these liabilities is based on Pinnacle Financial's pricing models that utilize observable market inputs and is reflected within Level 2 of the valuation hierarchy.

The following tables present financial instruments measured at fair value on a recurring basis as of June 30, 2021 and December 31, 2020, by caption on the consolidated balance sheets and by FASB ASC 820 valuation hierarchy (as described above) (in thousands):

In the case of the investment securities portfolio, Pinnacle Financial monitors the portfolio to ascertain when transfers between levels have been affected. The nature of the remaining assets and liabilities is such that transfers in and out of any level are expected to be rare. For the six months ended June 30, 2021, there were no transfers between Levels 1, 2 or 3.

The table below includes a rollforward of the balance sheet amounts for the three and six months ended June 30, 2021 and June 30, 2020 (including the change in fair value) for financial instruments classified by Pinnacle Financial within Level 3 of the valuation hierarchy measured at fair value on a recurring basis including changes in fair value due in part to observable factors that are part of the valuation methodology (in thousands):

The following tables present the carrying amounts, estimated fair value and placement in the fair value hierarchy of Pinnacle Financial's financial instruments at June 30, 2021 and December 31, 2020.  This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash, cash equivalents, and restricted cash, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as non-interest bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity (in thousands):

(1)Estimated fair values are consistent with an exit-price concept. The assumptions used to estimate the fair values are intended to approximate those that a market-participant would realize in a hypothetical orderly transaction.

(2)At the end of each quarter, Pinnacle Financial evaluates the inherent risks of the outstanding off-balance sheet commitments, including both commitments for unfunded loans and standby letters of credit. In making this evaluation, Pinnacle Financial utilizes credit loss expectations on funded loans from our allowance for credit losses methodology and evaluates the probability that the outstanding commitment will eventually become a funded loan. As a result, at June 30, 2021 and December 31, 2020, Pinnacle Financial included in other liabilities $23.2 million, representing expected credit losses on off-balance sheet commitments, which are reflected in the estimated fair values of the related commitments. Also included in the fair values at June 30, 2021 and December 31, 2020 are unamortized fees related to these commitments of $1.8 million and $1.7 million, respectively.

Note 10. Regulatory Matters

Pursuant to Tennessee banking law, Pinnacle Bank may not, without the prior consent of the Commissioner of the Tennessee Department of Financial Institutions (TDFI), pay any dividends to Pinnacle Financial in a calendar year in excess of the total of Pinnacle Bank's retained net income for that year plus the retained net income for the preceding two years. Under Tennessee corporate law, Pinnacle Financial is not permitted to pay dividends if, after giving effect to such payment, it would not be able to pay its debts as they become due in the usual course of business or its total assets would be less than the sum of its total liabilities plus any amounts needed to satisfy any preferential rights if it were dissolving. In addition, in deciding whether or not to declare a dividend of any particular size, Pinnacle Financial's board of directors must consider its and Pinnacle Bank's current and prospective capital, liquidity, and other needs. In addition to state law limitations on Pinnacle Financial's ability to pay dividends, the Federal Reserve imposes limitations on Pinnacle Financial's ability to pay dividends. Federal Reserve regulations limit dividends, stock repurchases and discretionary bonuses to executive officers if Pinnacle Financial's regulatory capital is below the level of regulatory minimums plus the applicable capital conservation buffer.

In addition, the Federal Reserve has issued supervisory guidance advising bank holding companies to eliminate, defer or reduce dividends paid on common stock and other forms of Tier 1 capital where the company’s net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends, the company’s prospective rate of earnings retention is not consistent with the company’s capital needs and overall current and prospective financial condition or the company will not meet, or is in danger of not meeting, minimum regulatory capital adequacy ratios. Recent supplements to this guidance reiterate the need for bank holding companies to inform their applicable reserve bank sufficiently in advance of the proposed payment of a dividend in certain circumstances.

During the six months ended June 30, 2021, Pinnacle Bank paid $23.3 million dividends to Pinnacle Financial. As of June 30, 2021, Pinnacle Bank could pay approximately $681.9 million of additional dividends to Pinnacle Financial without prior approval of the Commissioner of the TDFI. Since the fourth quarter of 2013, Pinnacle Financial has paid a quarterly common stock dividend. The board of directors of Pinnacle Financial has increased the dividend amount per share over time. The most recent increase occurred on January 19, 2021, when the board of directors increased the dividend to $0.18 per common share from $0.16 per common share. During the second quarter of 2020, the Pinnacle Financial issued 9.0 million depositary shares, each representing a 1/40th fractional interest in a share of Series B noncumulative, perpetual preferred stock (the "Series B Preferred Stock") in a registered public offering to both retail and institutional investors. Beginning in the third quarter of 2020, Pinnacle Financial began paying a quarterly dividend of $16.88 per share (or $0.422 per depositary share), on the Series B Preferred Stock.

The amount and timing of all future dividend payments by Pinnacle Financial, if any, including dividends on Pinnacle Financial's Series B Preferred Stock, is subject to discretion of Pinnacle Financial's board of directors and will depend on Pinnacle Financial's receipt of dividends from Pinnacle Bank, earnings, capital position, financial condition and other factors, including regulatory capital requirements, as they become known to Pinnacle Financial and receipt of any regulatory approvals that may become required as a result of each of Pinnacle Financial's or Pinnacle Bank's financial results.

Pinnacle Financial and Pinnacle Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Pinnacle Financial and Pinnacle Bank must meet specific capital guidelines that involve quantitative measures of the assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Pinnacle Financial's and Pinnacle Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require Pinnacle Financial and its banking subsidiary to maintain minimum amounts and ratios of common equity Tier 1 capital to risk-weighted assets, Tier 1 capital to risk-weighted assets, total risk-based capital to risk-weighted assets and Tier 1 capital to average assets.

As permitted by the interim final rule issued on March 27, 2020 by the federal banking regulatory agencies, each of Pinnacle Bank and Pinnacle Financial has elected the option to delay the estimated impact on regulatory capital of Pinnacle Financial's and Pinnacle Bank's adoption of ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which was effective January 1, 2020. The initial impact of adoption of ASU 2016-13, as well as 25% of the quarterly changes in the allowance for credit losses subsequent to adoption of ASU 2016-13 (collectively the “transition adjustments”), will be delayed until December 31, 2021. After that date, the cumulative amount of the transition adjustments will become fixed and will be phased out of the regulatory capital calculations evenly over a three year period, with 75% recognized in

2022, 50% recognized in 2023, and 25% recognized in 2024. Beginning on January 1, 2025, the temporary regulatory capital benefits will be fully reversed.

Management believes, as of June 30, 2021, that Pinnacle Financial and Pinnacle Bank met all capital adequacy requirements to which they are subject. To be categorized as well-capitalized under applicable banking regulations, Pinnacle Bank must maintain certain total risk-based, Tier 1 risk-based, common equity Tier 1 and Tier 1 leverage ratios as set forth in the following table and not be subject to a written agreement, order or directive to maintain a higher capital level. The capital conservation buffer is not included in the required ratios of the table presented below. Pinnacle Financial's and Pinnacle Bank's actual capital amounts and resulting ratios, not including the capital conservation buffer, are presented in the following table (in thousands):

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is a discussion of our financial condition at June 30, 2021 and December 31, 2020 and our results of operations for the three and six months ended June 30, 2021 and 2020. The purpose of this discussion is to focus on information about our financial condition and results of operations which is not otherwise apparent from our consolidated financial statements. The following discussion and analysis should be read along with our consolidated financial statements and the related notes included elsewhere herein and the risk factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2020 (Form 10-K) and the other reports we have filed with the Securities and Exchange Commission since we filed that Form 10-K.

Impact of COVID-19 Pandemic

The outbreak and continued spread of a novel strain of the coronavirus or, COVID-19, has created a global public health crisis that has resulted in unprecedented uncertainty, volatility and disruption in financial markets and in governmental, commercial and consumer activity in the United States and globally, including the markets that we serve. These actions included the decision by the Federal Reserve Open Markets Committee to lower the target for the federal funds rate to a range of between zero to 0.25% on March 15, 2020. This action followed a prior reduction of the targeted federal funds rate to a range of 1.0% to 1.25% on March 3, 2020.

We have been intentional in our response throughout the COVID-19 pandemic to ensure strength in our balance sheet, including, initially, increases in liquidity and reserves. As a part of this intentional response, we conducted an extensive loan review and re-risk grading process in 2020 of various types, sizes and grades of loans. During the second quarter of 2020, we performed an in-depth review of all risk-graded loans greater than $1.0 million for which we had granted the borrower the ability to defer the payment of principal and/or interest for a period of up to 90 days following the COVID-19 outbreak. We also performed an in-depth review of all of our hotel and retail commercial real estate loans greater than $1.0 million regardless of their receipt of deferral. During the third quarter of 2020, our focus broadened to include the other segments of the portfolio that are risk rated that we did not re-risk grade during the second quarter. This extensive re-underwriting effort included our pass grade loans with exposures greater than $2.0 million and watch list, criticized or classified loans with exposures greater than $500,000. During the fourth quarter of 2020 and again in the first quarter of 2021, we performed a follow-up in-depth review of hotel loans $1.0 million and greater, all non-pass grade exposures greater than $500,000 and a comprehensive review of loans with a low pass risk grade known to be impacted by the COVID-19 pandemic. During the second quarter of 2021, we again performed a follow-up in-depth review of hotel loans $1.0 million and greater and all non-pass grade exposures greater than $500,000. We intend to continue our very disciplined level of re-risk grading the hotel portfolio and our focus on COVID-impacted low pass graded loans throughout the remainder of 2021.

Additionally throughout 2020 and into the first half of 2021 in response to the pandemic, we adjusted our business practices, including restricting employee travel, encouraging employees to work from home where possible, offering, until April 2021, drive-thru only service at certain of our locations with specific needs facilitated by appointment, implementing social distancing guidelines within our offices and continuing to hold regular meetings of our pandemic response team. Many of these measures remain in place due to the continued prevalence of the virus, though, in April 2021, we began re-opening our customer locations and bringing employees back into the office with a phased approach. As of September 1, 2021, our phased approach should be complete with substantially all employees back in offices barring no change to circumstances surrounding the virus or its variants in our markets.

As of July 13, 2021, under the Paycheck Protection Program, we had submitted applications and received funding of approximately $3.4 billion, of which, approximately $2.0 billion had received forgiveness or had been paid down as of that date. We believe that we were effective in each round of the PPP in assisting the small businesses in our markets that have been, and in certain cases continue to be, impacted by the pandemic. Inclusive of fees from the SBA, our yield on PPP loans during the three and six months ended June 30, 2021 were 5.47% and 4.98%, respectively.

As a result of the pandemic, we also implemented a short-term loan modification program to provide temporary payment relief to certain of our borrowers. This program allowed for a deferral of principal and/or interest payments for 90 days, which may have been extended for an additional 90 days, for a maximum of 180 days on a cumulative and successive basis. For borrowers requiring a longer-term modification following the short-term loan modification program, we worked with eligible borrowers to modify such loans under Section 4013 of the CARES Act. The outstanding balance at June 30, 2021 of loans which have received these Section 4013 modifications was approximately $817.4 million compared to approximately $825.6 million at December 31, 2020.

We continue to believe our response to the pandemic has allowed and continues to allow us to appropriately support our associates and clients and their communities. The COVID-19 pandemic along with the implementation of CECL contributed to an increased provision for credit losses in 2020 and an extended duration of economic disruption resulting from the virus could lead to increased net charge-offs and further elevated levels of provisioning expense. We continue to monitor the impact of COVID-19 and the effect new variants or mutations may have, the administration, efficacy and public acceptance of COVID-19 vaccines, the effects of the

CARES Act, Coronavirus Relief Act, American Relief Act and the prospects for additional fiscal stimulus programs closely. Accordingly, the COVID-19 pandemic continues to impact our operations and the operations of certain of our customers, though in the second quarter of 2021 the impact appeared to be lessening as the average number of cases, hospitalizations and deaths in most of our markets continued to be below the levels experienced at the height of the pandemic, and the number of residents in our markets that have been vaccinated against the virus continued to rise and economic activity increased; however, our ability and the ability of our customers to recover from the pandemic remains uncertain and will depend on continued decline in the severity of COVID-19 and emergence of other variants of the virus in our markets (including the Delta variant) and government responses thereto, as well as continued improvement in economic conditions in those markets.

Overview

Our diluted net income per common share for the three and six months ended June 30, 2021 was $1.69 and $3.30, respectively, compared to $0.83 and $1.20, respectively, for the same periods in 2020. At June 30, 2021, loans increased to $22.9 billion, as compared to $22.4 billion at December 31, 2020, and total deposits increased to $28.2 billion at June 30, 2021 from $27.7 billion at December 31, 2020.

Results of Operations.  Our net interest income increased to $233.2 million and $456.1 million, respectively, for the three and six months ended June 30, 2021 compared to $200.7 million and $394.2 million, respectively, for the same periods in the prior year, representing an increase of $32.5 million and $61.9 million, respectively. For the three and six months ended June 30, 2021 when compared to the comparable periods in 2020, this increase was largely the result of lower cost of funds, the impact of both interest and fees related to PPP loans and our pay down of a portion of the additional liquidity we acquired in 2020 in response to the economic uncertainty resulting from the COVID-19 pandemic, as well as organic loan growth when comparing the comparable periods. The net interest margin (the ratio of net interest income to average earning assets) for the three and six months ended June 30, 2021 was 3.08% and 3.05%, respectively, compared to 2.87% and 3.06%, respectively, for the same periods in 2020 and reflects the impact of loans made and fees recognized pursuant to the PPP and our acquisition and subsequent pay down of additional on-balance sheet liquidity as noted above, the decline in short-term interest rates, declining levels of positive impact from purchase accounting and the competitive rate environments for loans and deposits in our markets.

Our provision for credit losses was $2.8 million and $10.1 million, respectively, for the three and six months ended June 30, 2021 compared to $68.3 million and $168.2 million, respectively, for the same periods in 2020. The decrease in provision expense in the first and second quarters of 2021 as compared to the same periods in 2020 is primarily due to improvements in current and projected economic conditions through June 30, 2021, as compared to the economic deterioration that occurred or was anticipated during the first six months of 2020 as a result of COVID-19. Also contributing to the provision expense for the three and six months ended June 30, 2021 were net charge-offs totaling $10.0 million and $21.4 million, respectively, compared to $5.4 million and $15.5 million, respectively, for the same periods in 2020.

At June 30, 2021, our allowance for credit losses as a percentage of total loans, inclusive of PPP loans, was 1.20% compared to 1.27% at December 31, 2020. The decrease in the allowance for credit losses is largely the result of improvements in the macroeconomic forecasts utilized by our CECL models to estimate future credit losses.

Noninterest income increased by $25.3 million, or 34.6%, and $47.6, or 33.2%, respectively, during the three and six months ended June 30, 2021 compared to the same periods in 2020. The growth in noninterest income was in large part attributable to an increase in income from our equity method investment in BHG of $14.9 million, or 86.4%, and $28.2, or 86.0%, respectively, during the three and six months ended June 30, 2021 compared to the same periods in the prior year as well as an increase in wealth management revenues which were $16.5 million and $32.6 million, respectively, for the three and six months ended June 30, 2021 compared to $12.2 million and $28.8 million, respectively, in the same periods in the prior year. These increases were offset by a decline in gains on mortgage loans sold, net, which decreased by $12.9 million and $7.8 million, respectively, for the three and six months ended June 30, 2021 as compared to the same periods in the prior year as rate environment fluctuations and declines in housing inventory in our markets negatively impacted originations. Additionally, we had $366,000 in net gains on sales of securities, respectively, during both the three and six months ended June 30, 2021 compared to $128,000 in net losses and $335,000 in net gains, respectively, in the same periods in the the prior year. Other noninterest income, which is the result of fee revenue lines of business other than those noted above, increased during the three and six months ended June 30, 2021 by $16.5 million and $22.1 million, respectively, when compared to the same periods in the prior year. This increase is largely the result of significant gains in the value of other equity investments which are up due to updated market valuations for certain of these investments as well as increases in SBA loan sales revenue which is up due to increased volumes and premiums which are at historically high levels for these types of loan sales.

Noninterest expense increased by $34.5 million, or 26.2%, and $51.9 million, or 19.3%, respectively, during the three and six months ended June 30, 2021 compared to the three and six months ended June 30, 2020. Impacting noninterest expense for the three and six months ended June 30, 2021 as compared to the same prior year periods was a $36.9 million and $59.2 million, respectively, increase

in salaries and employee benefits. The change in salaries and employee benefits was primarily the result of the accrual at above-target levels for both our cash and equity incentive plans during the three and six months ended June 30, 2021 versus an accrual at below-target payout under such plans during the same periods in 2020. Also impacting salaries and employee benefits was an increase in our associate base in 2021 versus 2020 as well as annual merit increases effective in January 2021. Additionally, noninterest expense in the three and six months ended June 30, 2020 was impacted by lending related costs related to an increase in our off-balance sheet reserves. The higher level of expense related to off-balance sheet reserves is due to the effect that macroeconomic factors impacted by the COVID-19 pandemic had on our CECL models during the three and six months ended June 30, 2020 subsequent to the implementation of CECL effective January 1, 2020. No such additional expense related to off-balance sheet reserves was recorded in the first six months of 2021.

Our efficiency ratio (the ratio of noninterest expense to the sum of net interest income and noninterest income) was 50.1% and 49.6%, respectively, for the three and six months ended June 30, 2021 compared to 48.1% and 50.0%, respectively, for the same periods in 2020. The efficiency ratio measures the amount of expense that is incurred to generate a dollar of revenue.

During the three and six months ended June 30, 2021, we recorded income tax expense of $30.7 million and $58.9 million, respectively, compared to $11.2 million and $9.6 million, respectively, for the three and six months ended June 30, 2020. Our effective tax rate for the three and six months ended June 30, 2021 was 18.9% and 18.6%, respectively, compared to 15.2% and 9.5%, respectively, for the three and six months ended June 30, 2020. Our tax expense in the first six months of 2020 was impacted by the increased provision for credit losses we recorded during that time period as discussed above, a portion of which was recorded as a discrete item of total income tax in the first quarter of 2020. Our tax rate in each period was also impacted by the vesting and exercise of equity-based awards previously granted under our equity-based compensation program, resulting in the recognition of tax benefits of $302,000 and $1.9 million, respectively, for the three and six months ended June 30, 2021 compared to tax expense of $272,000 and a tax benefit of $590,000, respectively, for the three and six months ended June 30, 2020.

Financial Condition. Loans increased $473.4 million, or 2.1%, during the six months ended June 30, 2021, when compared to December 31, 2020. The increase is primarily the result of loans made to borrowers that principally operate or are located in our core markets, increases in the number of relationship advisors we employ and continued focus on attracting new customers to our company offset in part by a decrease in the number of PPP loans in our portfolio as these loans are paid down or forgiven by the SBA. Total deposits were $28.2 billion at June 30, 2021, compared to $27.7 billion at December 31, 2020, an increase of $512.0 million, or 1.8%. Deposit growth during the period was likely aided by our clients' continued desire to hold onto liquidity as they support their businesses through the continued economic uncertainty as a result of the COVID-19 pandemic, proceeds from the PPP and other government stimulus programs not yet deployed and current stock market conditions, but was also due in part to our intentional emphasis on gathering low-cost core deposits during both periods.

Capital and Liquidity. At June 30, 2021 and December 31, 2020, our capital ratios, including our bank's capital ratios, exceeded regulatory minimum capital requirements and those necessary to be considered well-capitalized under applicable federal regulations. See Note 10. Regulatory Matters in the Notes to our Consolidated Financial Statements elsewhere in this Form 10-Q for additional information regarding our capital ratios. From time to time we may be required to support the capital needs of our bank (Pinnacle Bank). At June 30, 2021, we had approximately $263.5 million of cash at the parent company that could be used to support our bank.

During the second quarter of 2020, we issued 9.0 million depositary shares, each representing a 1/40th interest in a share of our 6.75% fixed rate non-cumulative, perpetual preferred stock, Series B (Series B Preferred Stock) in a registered public offering to both retail and institutional investors. Net proceeds from the transaction after underwriting discounts and offering expenses payable by us were approximately $217.1 million. The net proceeds were retained at Pinnacle Financial and the remaining portion thereof is available to support our capital needs and other obligations, including payments related to our outstanding indebtedness, to support the capital needs and other obligations of our bank and for other general corporate purposes. Additionally, we believe we have various capital raising techniques available to us to provide for the capital needs of our company and bank, such as a subordinated debt offering or entering into a new revolving credit facility with another financial institution. We also periodically evaluate capital markets conditions to identify opportunities to access those markets if necessary or prudent to support our capital levels.

During the quarter ended March 31, 2020, we repurchased approximately 1.0 million shares of our common stock at an aggregate cost of $50.8 million under our previously authorized share repurchase agreement. Our last purchase of shares of our common stock under the prior share repurchase program occurred on March 19, 2020, as we suspended the program due to uncertainty surrounding the COVID-19 pandemic and it remained suspended until its expiration on December 31, 2020. On January 19, 2021, our board of directors authorized a share repurchase program for up to $125.0 million of our outstanding common stock. The authorization for this program will remain in effect through March 31, 2022. We did not repurchase any shares under our current share repurchase program during the six months ended June 30, 2021.

Critical Accounting Estimates

The accounting principles we follow and our methods of applying these principles conform with U.S. GAAP and with general practices within the banking industry. On January 1, 2020, we adopted FASB ASU 2016-13 Financial Instruments - Credit Losses (Topic 326) which significantly changes our methodology for determining our allowance for credit losses, and ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment which simplifies our process for performing goodwill impairment testing. There have been no other significant changes to our Critical Accounting Estimates as described in our Form 10-K.

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. Net interest income totaled $233.2 million and $456.1 million, respectively, for the three and six months ended June 30, 2021 compared to $200.7 million and $394.2 million, respectively, for the same periods in the prior year, representing increases of $32.6 million and $61.9 million, respectively. For the three and six months ended June 30, 2021 when compared to the comparable periods in 2020, this increase was largely the result of lower cost of funds, the impact of both interest and fees related to the PPP and our pay down of a portion of the additional liquidity we acquired in 2020 in response to the economic uncertainty resulting from the COVID-19 pandemic as well as organic loan growth during the comparable periods offset in part by yield compression in our earning asset portfolio.

The following tables set 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 and six months ended June 30, 2021 and 2020 (dollars in thousands):

(1) Average balances of nonaccrual loans are included in the above amounts.

(2) Yields computed on tax-exempt instruments on a tax equivalent basis and include $15.2 million of taxable equivalent income for the six months ended June 30, 2021 compared to $14.0 million for the six months ended June 30, 2020. The tax-exempt benefit has been reduced by the projected impact of tax-exempt income that will be disallowed pursuant to IRS Regulations as of and for the period presented.

(3) Yields realized on interest-bearing assets less the rates paid on interest-bearing liabilities. The net interest spread calculation excludes the impact of demand deposits. Had the impact of demand deposits been included, the net interest spread for the six months ended June 30, 2021 would have been 3.04% compared to a net interest spread of 3.02% for the six months ended June 30, 2020.

(4) Net interest margin is the result of annualized net interest income calculated on a tax-equivalent basis divided by average interest-earning assets for the period.

For the three and six months ended June 30, 2021, our net interest margin was 3.08% and 3.05%, respectively, compared to 2.87% and 3.06%, respectively, for the same periods in 2020. Our net interest margin for the three and six months ended June 30, 2021 reflects the impact of loans made, and fees recognized, pursuant to the PPP and our acquisition and subsequent pay down of additional on-balance sheet liquidity as noted above, the continued historically low levels for short-term interest rates, declining levels of positive impact from purchase accounting and the competitive rate environments for loans and deposits in our markets. More specifically, our net interest margin was negatively impacted by yield compression in our earning asset portfolio due to a historically low macroeconomic interest rate environment, the result of a 150 basis points reduction in the federal funds rate in March 2020. During the three and six months ended June 30, 2021, our earning asset yield decreased by 16 basis points and 55 basis points, respectively, from

the same periods in the prior year. Our total funding rates decreased by 39 basis points and 56 basis points during the three and six months ended June 30, 2021, respectively, compared to the same periods in the prior year.

We continue to deploy various asset liability management strategies to manage our risk to interest rate fluctuations. Pricing for creditworthy borrowers and meaningful depositors is very competitive in our markets and this competition has adversely impacted, and may continue to adversely impact, our margins. We believe this challenging competitive environment will continue throughout the remainder of 2021, even during a time of economic uncertainty due to COVID-19. Our strategy of adding additional on-balance sheet liquidity to aid in managing through the early uncertainties of COVID-19, as well as the meaningful increase in core deposit inflows we experienced in 2020 and the first half of 2021 has and will continue to negatively impact the net interest margin until on-balance sheet liquidity returns to more normalized levels.

Provision for Credit Losses. The provision for credit losses represents a charge to earnings necessary to establish an allowance for credit losses that, in management's evaluation, is adequate to provide coverage for all expected credit losses. The provision for credit losses amounted to $2.8 million and $10.1 million, respectively, for the three and six months ended June 30, 2021 compared to $68.3 million and $168.2 million, respectively, for the three and six months ended June 30, 2020. Provision expense is impacted by growth in our loan portfolio, recent historical and projected future economic conditions, our internal assessment of the credit quality of the loan portfolio, and net charge-offs. The lower provision expense during the first six months of 2021 as compared to the first six months of 2020 is the result of improvements in the current and projected economic conditions as compared to the economic deterioration which occurred during the first six months of 2020 related to the COVID-19 pandemic. Also contributing to provision expense in all periods are net charge-offs, which totaled $10.0 million and $21.4 million, respectively, for the three and six months ended June 30, 2021 compared to $5.4 million $15.5 million, respectively, for the same periods in 2020.

Noninterest Income.  Our noninterest income is composed of several components, some of which vary significantly between quarterly and annual periods. Service charges on deposit accounts and other noninterest income generally reflect customer growth trends, while fees from our wealth management departments, gains on mortgage loans sold, gains and losses on the sale of securities and gains or losses related to our efforts to mitigate risks associated with interest rate volatility will often reflect financial market conditions or our asset/liability management efforts and fluctuate from period to period.

The following is a summary of our noninterest income for the three and six months ended June 30, 2021 and 2020 (in thousands):

	Three Months Ended June 30,				2021 - 2020	Six Months Ended June 30,				2021 - 2020
	2021		2020		Increase (Decrease)	2021		2020		Increase (Decrease)

Gains (losses) on other equity investments	6,956		(278)		> 100%	10,396		(452)		> 100%
Other noninterest income	3,045		2,859		6.5%	5,212		4,942		5.5%
Total other noninterest income	33,699		17,185		96.1%	59,382		37,243		59.4%
Total noninterest income	$	98,207	$	72,954	34.6%	$	190,916	$	143,331	33.2%

The increase in service charges on deposit accounts in the three and six months ended June 30, 2021 compared to the three and six months ended June 30, 2020 relates to an increase in analysis fees, including fee waivers, and increased transaction volumes in commercial checking accounts which we believe is the result of the increased economic activity in our markets from the closures that were the result of the COVID-19 pandemic.

Income from our wealth management groups (investments, insurance and trust) is also included in noninterest income. For the three and six months ended June 30, 2021, commissions and fees from investment services at our financial advisory unit, Pinnacle Asset Management, a division of Pinnacle Bank, and fees from our wealth advisory group, PNFP Capital Markets, Inc., increased by $3.0 million and $2.0 million, respectively, when compared to the three and six months ended June 30, 2020. At June 30, 2021 and 2020, Pinnacle Asset Management was receiving commissions and fees in connection with approximately $6.3 billion and $4.5 billion, respectively, in brokerage assets. These fees increased $4.3 million during the six months ended June 30, 2021 when compared to the six months ended June 30, 2020 and were offset by a decline in investment advisory fees from PNFP Capital Markets, Inc. which decreased $2.3 million for the six months ended June 30, 2021 when compared to the six months ended June 30, 2020. Revenues from the sale of insurance products by our insurance subsidiaries for the three and six months ended June 30, 2021 increased by $175,000 and $160,000, respectively, compared to the same periods in the prior year. Included in insurance revenues for the six months ended June 30, 2021 was $927,000 of contingent income received in the first quarter of 2021 that was based on 2020 sales production and claims experience compared to $1.1 million recorded in the same period in the prior year. Additionally, at June 30, 2021, our trust department was receiving fees on approximately $3.6 billion of managed assets compared to $2.9 billion at June 30, 2020, reflecting organic growth and increased market valuations. We believe the change in our wealth management businesses during the three and six months ended June 30, 2021 when compared to the comparable periods in 2020 is primarily attributable to market volatility resulting from the uncertainty surrounding the COVID-19 pandemic and its ongoing impact.

Gains on mortgage loans sold, net, consists of fees from the origination and sale of mortgage loans. These mortgage fees are for loans primarily originated in our current markets that are subsequently sold to third-party investors. Substantially all of these loan sales transfer servicing rights to the buyer. Generally, mortgage origination fees increase in lower interest rate environments and more robust housing markets and decrease in rising interest rate environments and more challenging housing markets. Mortgage origination fees will fluctuate from quarter to quarter as the rate environment changes. Gains on mortgage loans sold, net, were $6.7 million and $20.4 million, respectively, for the three and six months ended June 30, 2021 compared to $19.6 million and $28.2 million, respectively, for the same periods in the prior year. This decrease is the direct result of the fluctuations in the rate environment and the decrease in housing inventory in the markets we operate negatively impacting originations. We hedge a portion of our mortgage pipeline as part of a mandatory delivery program. The hedge is not designated as a hedge for GAAP purposes and, as such, changes in its fair value are recorded directly through the income statement. There is a positive correlation between the dollar amount of the mortgage pipeline and the value of this hedge. Therefore, the change in the outstanding mortgage pipeline at the end of any reporting period will directly impact the amount of gain recorded for mortgage loans held for sale during that reporting period. At June 30, 2021, the mortgage pipeline included $180.8 million in loans expected to close in 2021 compared to $340.7 million in loans at June 30, 2020 expected to close in 2020.

Investment gains and losses on sales, net represent the net gains and losses on sales of investment securities in our available-for-sale securities portfolio during the periods noted. During the three and six months ended June 30, 2021, $2.2 million of securities were sold for a net gain of $366,000 compared to the three and six months ended June 30, 2020, when we sold approximately $69.9 million and $100.1 million, respectively, of securities for a net loss of $128,000 and net gain of $335,000, respectively.

Income from equity-method investment. Income from equity-method investment is comprised solely of income from our 49% equity-method investment in BHG. BHG is engaged in the origination of commercial and consumer loans primarily to healthcare providers and other professionals throughout the United States. The loans originated by BHG are either financed by secured borrowings or sold without recourse to independent financial institutions and investors. BHG has expanded its operations to include commercial lending to other professional service firms such as attorneys, accountants and others.

Income from this equity-method investment was $32.1 million and $61.0 million, respectively, for the three and six months ended June 30, 2021 compared to $17.2 million and $32.8 million, respectively, for the same periods last year. Historically, BHG has sold the majority of the loans it originates to a network of bank purchasers through a combination of online auctions, direct sales and its direct purchase option. In the second half of 2019, BHG began retaining more loans on its balance sheet than historically had been the case in recent years. As a result of the economic disruption resulting from the COVID-19 pandemic, BHG, throughout 2020 and through the second quarter of 2021, sold more loans through its auction platform than we had previously anticipated and will likely continue to slow its transition to holding more loans on its balance sheet as the effects of COVID-19 are monitored. In the third quarter of 2020 and second quarter of 2021, BHG completed its first and second securitization issuances of approximately $160 million and $375 million, respectively, in notes backed by commercial and consumer loans on its balance sheet to provide additional funding.

Income from equity-method investment is recorded net of amortization expense associated with customer lists and other intangible assets of $188,000 and $376,000, respectively, for the three and six months ended June 30, 2021 compared to $293,000 and $587,000, respectively, for the three and six months ended June 30, 2020. At June 30, 2021, there were $7.2 million of these intangible assets that are expected to be amortized in lesser amounts over the next 14 years. Also included in income from equity-method investment is accretion income associated with the fair valuation of certain of BHG's liabilities of $395,000 and $846,000, respectively, for the three

and six months ended June 30, 2021, compared to $541,000 and $1.1 million, respectively, for the three and six months ended June 30, 2020. At June 30, 2021, there were $1.8 million of these liabilities that are expected to accrete into income in lesser amounts over the next five years.

During the three and six months ended June 30, 2021, Pinnacle Financial and Pinnacle Bank received $39.4 million and $49.4 million, respectively, in dividends from BHG in the aggregate. During the three months ended June 30, 2020, Pinnacle Financial and Pinnacle Bank received no dividends from BHG. During the six months ended June 30, 2020, Pinnacle Financial and Pinnacle Bank received $8.0 million in dividends from BHG in the aggregate. Dividends from BHG during such periods reduced the carrying amount of our investment in BHG, while earnings from BHG during such periods increased the carrying amount of our investment in BHG. Profits from intercompany transactions are eliminated. Our proportionate share of earnings from BHG is included in our consolidated tax return. During the three and six months ended June 30, 2021, Pinnacle Bank purchased $50.3 million and $124.9 million, respectively, in loans from BHG at par pursuant to BHG's joint venture loan program whereby BHG and Pinnacle share proportionately in the credit risk of the acquired loans based on the rate on the loan and the rate of the purchase. The yield on this portfolio to Pinnacle Bank is anticipated to be 4.75% per annum. No loans were purchased from BHG by Pinnacle Bank for the three and six months ended June 30, 2020.

For the three and six months ended June 30, 2021, BHG reported $179.0 million and $336.6 million, respectively, in revenues, net of substitution losses of $25.0 million and $53.5 million, respectively, compared to revenues of $92.8 million and $190.7 million, respectively, for the three and six months ended June 30, 2020, net of substitution losses of $28.1 million and $44.4 million, respectively. Earnings from BHG are likely to fluctuate from period-to-period. Approximately $127.5 million and $243.5 million, respectively, of BHG's revenues for the three and six months ended June 30, 2021 related to gains on the sale of commercial loans compared to $67.3 million and $136.9 million, respectively, for the three and six months ended June 30, 2020. These loans have typically been sold by BHG with no recourse to a network of community banks and other financial institutions at a premium to the par value of the loan. The purchaser may access a BHG cash reserve account of up to 3% of the loan balance to support loan payments. BHG retains no servicing or other responsibilities related to the core product loan once sold. As a result, this gain on sale premium represents BHG's compensation for absorbing the costs to originate the loan as well as marketing expenses associated with maintaining its business model. At June 30, 2021 and 2020, there were $4.0 billion and $3.2 billion, respectively, of these loans previously sold by BHG that were being actively serviced by BHG's network of bank purchasers. BHG, at its sole option, may also provide purchasers of these loans the ability to substitute the acquired loan with another more recently-issued BHG loan should the previously-acquired loan become at least 90-days past due as to its monthly payments. As a result, BHG maintained a liability as of June 30, 2021 and 2020 of $267.1 million and $229.3 million, respectively, that represents an estimate of the future inherent losses for the outstanding core portfolio that may be subject to future substitution due to payment default or loan prepayment. This liability represents 6.7% and 7.2%, respectively, of core product loans previously sold by BHG that remain outstanding as of June 30, 2021 and 2020, respectively. The decrease in this liability in the six months ended June 30, 2021 compared to the period ended June 30, 2020 was principally the result of a partial release of the reserve BHG recorded in 2020 related to the economic disruption associated with the COVID-19 pandemic which adversely impacted physician and dental practices in a material manner.

In addition to these loans that BHG sells into its auction market, at June 30, 2021, BHG reported loans that remained on BHG's balance sheet totaling $1.6 billion compared to $839.3 million as of June 30, 2020. A portion of these loans do not qualify for sale accounting and accordingly an offsetting secured borrowing liability has been recorded. At June 30, 2021 and 2020, BHG had $1.1 billion and $310.4 million, respectively, of secured borrowings associated with loans held for investment which did not qualify for sale accounting. At June 30, 2021 and 2020, BHG reported allowance for loan losses totaling $33.7 million and $9.5 million, respectively, with respect to the loans on its balance sheet. Interest income and fees amounted to $44.0 million and $78.6 million, respectively, for the three and six months ended June 30, 2021 compared to $22.0 million and $46.1 million, respectively, for the three and six months ended June 30, 2020. 

Included in our other noninterest income are interchange and other consumer fees, gains from bank-owned life insurance, swap fees earned for the facilitation of derivative transactions for our clients, SBA loan sales, gains or losses on other equity investments and other noninterest income items. Interchange revenues increased 69.8% and 46.1%, respectively, during the three and six months ended June 30, 2021 as compared to the same periods in 2020 due to increased debit and credit card transactions period-over-period and unused line fees during the first half of 2021 as compared to the same period in 2020. Other noninterest income included changes in the cash surrender value of bank-owned life insurance which was $4.7 million and $9.5 million, respectively, for each of the three and six months ended June 30, 2021 compared to $4.7 million and $9.4 million, respectively, in the same periods in the prior year. The assets that support these policies are administered by the life insurance carriers and the income we recognize (i.e., increases or decreases in the cash surrender value of the policies) on these policies is dependent upon the crediting rates applied by the insurance carriers, which are subject to change at the discretion of the carriers, subject to any applicable floors. Earnings on these policies generally are not taxable. SBA loan sales are included in other noninterest income and increased by $2.9 million and $3.4 million, respectively, during the three and six months ended June 30, 2021 when compared to the same periods in the prior year. The increase is due to increased volumes as well as historically high premiums. Additionally, the carrying values of other equity investments are

adjusted either upwards or downwards from the transaction price to reflect expected exit values as evidenced by financing and sale transactions with third parties, or when determination of a valuation adjustment is confirmed through ongoing reviews by senior investment managers. Income related to these investments increased $7.2 million and $10.8 million, respectively, during the three and six months ended June 30, 2021 when compared to the same periods in the prior year, as a result of increased valuations with respect to certain investments. Loan swap fees increased by $371,000 and decreased by $913,000, respectively, during the three and six months ended June 30, 2021 as compared to the same periods in 2020 due primarily to a change in the volume of activity resulting from the current interest rate environment. The other components of other noninterest income increased only slightly during the three and six months ended June 30, 2021 as compared to the same periods in 2020 and includes all other noninterest income not included in the above noted categories.

Noninterest Expense.  Noninterest expense consists of salaries and employee benefits, equipment and occupancy expenses, other real estate expenses, and other operating expenses. The following is a summary of our noninterest expense for the three and six months ended June 30, 2021 and 2020 (in thousands):

	Three Months Ended June 30,				2021 - 2020	Six Months Ended June 30,				2021 - 2020

Total noninterest expense	$	166,140	$	131,605	26.2%	$	320,836	$	268,954	19.3%

Total salaries and employee benefits expenses increased $36.9 million and $59.2 million, respectively, for the three and six months ended June 30, 2021 compared to the same periods in 2020. The change in salaries and employee benefits was the largely the result of the accrual of our cash and equity incentive plans at above-target levels during the three and six months ended June 30, 2021 compared to an accrual at below-target levels due to the effects of COVID-19 on our anticipated earnings and performance during the same periods in the prior year. Also impacting salaries and employee benefits was an increase in our associate base in 2021 versus 2020 as well as annual merit increases effective in January 2021. Our associate base increased to 2,706.0 full-time equivalent associates at June 30, 2021 from 2,577.5 at June 30, 2020. We expect salary and benefit expenses will rise in 2021 compared to 2020 as we continue our focus on hiring experienced bankers in all of our markets, particularly if we continue to accrue cash and equity incentives at above-target payout based on anticipated earnings and performance in 2021.

We believe that cash and equity incentives are a valuable tool in motivating an associate base that is focused on providing our clients effective financial advice and increasing shareholder value. As a result, and unlike many other financial institutions, all of our bank's non-commissioned associates participate in our annual cash incentive plan with a minimum targeted bonus equal to 10% of each associate's annual salary, and all of our bank's associates participate in our equity compensation plans. Under the 2021 annual cash incentive plan, the targeted level of incentive payments requires achievement of a certain soundness threshold and a targeted level of quarterly pre-tax, pre-provision net revenue (PPNR) and annual earnings per common share (subject to certain adjustments). To the extent that the soundness threshold is met and PPNR and earnings per common share are above or below the targeted amount, the aggregate incentive payments are increased or decreased. Historically, we have paid between 0% and 125% of our targeted incentives.

Table of Contents

For 2021, maximum payouts under the plan could reach 160% of target. Through the second quarter of 2021, we have accrued incentive costs for the cash incentive plan in 2021 at maximum payout of our targeted awards.

Also included in employee benefits and other expense for the three and six months ended June 30, 2021 were approximately $5.7 million and $11.1 million, respectively, of compensation expenses related to equity-based awards for restricted shares, restricted stock unit and performance stock unit awards, compared to $4.1 million and $9.6 million, respectively, for the three and six months ended June 30, 2020. Under our equity incentive plans, we provide a broad-based equity incentive program for all of our bank's associates. We believe that equity incentives provide a vehicle for all associates to become meaningful shareholders of Pinnacle Financial over an extended period of time and create a shareholder-centric culture throughout our organization. Our compensation expense associated with equity awards for the three and six months ended June 30, 2021 changed only modestly when compared to the three and six months ended June 30, 2020. Our compensation expense associated with equity awards with time-based vesting criteria is likely to continue to increase during the remainder of 2021 when compared to 2020 as a result of the increased number of associates and our intention to hire additional experienced financial advisors. Compensation expense associated with our performance-based vesting awards will continue to be impacted by our performance in 2021 and will likely be higher than the comparable prior year period during the remainder of 2021 as beginning in the second quarter of 2020 and for the remainder of the year we accrued for those awards at below-target levels. Through the first six months of 2021, we have accrued for those awards at above-target levels.

Employee benefits and other expenses were $15.5 million and $32.2 million, respectively, for the three and six months ended June 30, 2021 compared to $10.8 million and $24.8 million, respectively, for the three and six months ended June 30, 2020 and include costs associated with our 401k plan, health insurance and payroll taxes. These costs fluctuate based on changes in our associate base and the level of participation in these programs by our associates. Costs associated with our health insurance and 401k plan programs increased $2.8 million and $4.8 million, respectively, in the aggregate during the three and six months ended June 30, 2021 when compared to the same periods in 2020.

Equipment and occupancy expenses for the three and six months ended June 30, 2021 were $23.3 million and $46.5 million, respectively, compared to $22.0 million and $43.0 million, respectively, for the three and six months ended June 30, 2020. These costs were generally consistent between periods. We expect to incur additional costs in future periods as we continue to enhance both our current locations and our technology infrastructure. During the first half of 2021, two new office locations were opened, one in the North Carolina market and the other in the Middle Tennessee market. Additionally, during the second quarter of 2021, we announced our intention to move our corporate headquarters to a newly announced office tower in Nashville, where we will be a founding partner and sponsor of the project. This move is currently planned for 2025 and will impact equipment and occupancy costs as we plan for this move.

Other real estate income and expenses, net, for the three and six months ended June 30, 2021 was income of $657,000 and $670,000, respectively, as compared to expenses of $2.9 million and $5.3 million, respectively, for the same periods in the prior year. Included in the three and six months ended June 30, 2020 were writedowns of previously foreclosed upon properties to market value based on updated appraisals obtained during that same time period of $3.2 million and $5.4 million, respectively.

Marketing and business development expense for the three and six months ended June 30, 2021 was $2.7 million and $5.0 million, respectively, compared to $2.1 million and $5.4 million, respectively, for the three and six months ended June 30, 2020. The primary source of both the increase for the three months ended June 30, 2021 and the decrease for the six months ended June 30, 2021 as compared to the same periods in 2020 is the result of limited in-person client meetings and business development expenses that began at the end of the first quarter of 2020 and continued through the first quarter of 2021 as a result of the restrictions resulting from the COVID-19 pandemic. As was the case for many companies, as we began to see more restrictions lift in the second quarter of 2021 in our markets, marketing and business development expense began to correspondingly increase. We expect these costs to rise modestly and return to more normalized levels through the second half of 2021 taking into account anticipated increases associated with the associates we have hired over the last eighteen months.

Intangible amortization expense was $2.2 million and $4.4 million, respectively, for the three and six months ended June 30, 2021 compared to $2.5 million and $5.0 million, respectively, for the same periods in 2020. The following table outlines our amortizing intangible assets, their initial valuation and amortizable lives at June 30, 2021:

	Year acquired	Initial Valuation  (in millions)		Amortizable Life (in years)	Remaining Value (in millions)
Core Deposit Intangible:

BNC Trust	2017	1.9		10	1.1
Advocate Capital	2019	13.6		13	9.2

These assets are being amortized on an accelerated basis which reflects the anticipated life of the underlying assets. Amortization expense of these intangibles is estimated to decrease from $7.8 million to $4.6 million per year over the next five years with lesser amounts for the remaining amortization period.

Other noninterest expenses, which consists primarily of deposit, lending, wealth management and administrative expenses decreased by $395,000 and $3.7 million, respectively, for the three and six months ended June 30, 2021 when compared to the three and six months ended June 30, 2020. Deposit related expense increased by $1.4 million and $2.9 million, respectively, during the three and six months ended June 30, 2021 when compared to the same periods in 2020 largely the result of increased FDIC assessment costs primarily due to the firm's increased asset base. Lending-related expenses decreased $842,000 and $5.1 million, respectively, during the three and six months ended June 30, 2021 when compared to the same periods in 2020. This decrease is primarily the result of the effect that macroeconomic factors related to the COVID-19 pandemic had on expenses related to the reserve for off-balance sheet credit losses during the three and six months ended June 30, 2020. As a result of improving economic conditions, we did not build additional reserves for off-balance sheet credit losses during the three and six months ended June 30, 2021. Other noninterest expenses decreased in the three and six months ended June 30, 2021 as compared to the same periods in 2020 due to $2.9 million in FHLB prepayment penalties resulting from our prepayment of $392.5 million in FHLB borrowings during the second quarter of 2020. Wealth management related expenses remained relatively flat for the three and six months ended June 30, 2021 when compared to the same periods in 2020.

Our efficiency ratio (the ratio of noninterest expense to the sum of net interest income and noninterest income) was 50.1% and 49.6%, respectively, for the three and six months ended June 30, 2021 compared to 48.1% and 50.0%, respectively, for the same periods in 2020. The efficiency ratio measures the amount of expense that is incurred to generate a dollar of revenue. The efficiency ratio for the three and six months ended June 30, 2021 compared to the same periods in 2020 was impacted in part by increased noninterest expense during the periods as a result of increased salaries and employee benefits resulting from the accrual of our cash and equity incentives at above target levels during the quarter, a decrease in the amount of gains on mortgage loans sold and income from our equity method investment in BHG.

Income Taxes. During the three and six months ended June 30, 2021, we recorded income tax expense of $30.7 million and $58.9 million, respectively, compared to $11.2 million and $9.6 million, respectively, for the three and six months ended June 30, 2020. Our effective tax rate for the three and six months ended June 30, 2021 was 18.9% and 18.6%, respectively, compared 15.2% and 9.5%, respectively, for the three and six months ended June 30, 2020. Our effective tax rate differs from the combined federal and state income tax statutory rate in effect of 26.14% primarily due to our investments in bank-qualified municipal securities, tax benefits from our real estate investment trust subsidiary, participation in Tennessee's Community Investment Tax Credit (CITC) program, tax benefits associated with share-based compensation, bank-owned life insurance and our captive insurance subsidiary, offset in part by the limitation on deductibility of meals and entertainment expense, non-deductible FDIC insurance premiums and non-deductible executive compensation. Our tax expense in the six months ended June 30, 2020 was impacted by the provision expense recorded in response to the COVID-19 pandemic, which was recorded in the first quarter of 2020 as a discrete item of total income tax and contributed a tax benefit of $22.4 million. Our tax rate in each period was also impacted by the vesting and exercise of equity-based awards previously granted under our equity-based compensation program, resulting in the recognition of tax benefits of $302,000 and $1.9 million, respectively, for the three and six months ended June 30, 2021 compared to tax expense of $272,000 and tax benefits of $590,000, respectively, for the three and six months ended June 30, 2020.

Financial Condition

Our consolidated balance sheet at June 30, 2021 reflects an increase in total loans outstanding to $22.9 billion compared to $22.4 billion at December 31, 2020. Total deposits increased by $512.0 million between December 31, 2020 and June 30, 2021. Total assets were $35.4 billion at June 30, 2021 compared to $34.9 billion at December 31, 2020.

Loans.  The composition of loans at June 30, 2021 and at December 31, 2020 and the percentage (%) of each classification to total loans are summarized as follows (in thousands):

	June 30, 2021				December 31, 2020
	Amount		Percent		Amount		Percent
Commercial real estate:

Consumer real estate – mortgage	3,335,537		14.6	%	3,099,172		13.8	%

Total loans	$	22,897,935	100.0	%	$	22,424,501	100.0	%

At June 30, 2021, our loan portfolio composition had changed modestly from the composition at December 31, 2020 principally as a result of the PPP loans, which are classified as commercial and industrial loans, though commercial real estate and commercial and industrial lending generally continue to make up the largest segments of our portfolio. At June 30, 2021, approximately 34.4% of the outstanding principal balance of our commercial real estate loans was secured by owner-occupied commercial real estate properties, compared to 35.0% at December 31, 2020. Owner occupied commercial real estate is similar in many ways to our commercial and industrial lending in that these loans are generally made to businesses on the basis of the cash flows of the business rather than on the valuation of the real estate. Additionally, the construction and land development loan segment continues to be a meaningful portion of our portfolio and reflects the development and growth of the local communities in which we operate and is diversified between commercial, residential and land.

Banking regulations have established guidelines for the construction ratio of less than 100% of total risk-based capital and for the non-owner occupied ratio of less than 300% of total risk-based capital. Should a bank’s ratios be in excess of these guidelines, banking regulations generally require an increased level of monitoring in these lending areas by bank management. Both ratios are calculated by dividing certain types of loan balances for each of the two categories by Pinnacle Bank’s total risk-based capital. At June 30, 2021, Pinnacle Bank’s construction and land development loans as a percentage of total risk-based capital was 80.1% compared to 89.0% at December 31, 2020. Construction and land development, non-owner occupied commercial real estate and multifamily loans as a percentage of total risk-based capital were 248.8% and 264.0% as of June 30, 2021 and December 31, 2020, respectively. At June 30, 2021, Pinnacle Bank was within the 100% and 300% guidelines and has established what it believes to be appropriate controls to monitor its lending in these areas as it aims to keep the level of these loans to below the 100% and 300% thresholds.

Loans in Past Due Status.  The following table is a summary of our loans that were past due at least 30 days but less than 89 days and 90 days or more past due as of June 30, 2021 and December 31, 2020 (in thousands):

Potential Problem Loans. Potential problem loans, which are not included in nonperforming assets, amounted to approximately $169.3 million, or 0.7% of total loans at June 30, 2021, compared to $173.5 million, or 0.8% of total loans at December 31, 2020. Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have doubts about the borrower's ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators, for loans classified as substandard, excluding the impact of substandard nonaccrual loans and substandard troubled debt restructurings. Troubled debt restructurings are not included in potential problem loans. Approximately $2.7 million of potential problem loans were past due at least 30 days but less than 90 days as of June 30, 2021.

Nonperforming Assets and Troubled Debt Restructurings. At June 30, 2021, we had $62.7 million in nonperforming assets compared to $86.2 million at December 31, 2020. Included in nonperforming assets were $53.1 million in nonaccrual loans and $9.6 million in OREO and other nonperforming assets at June 30, 2021 and $73.8 million in nonaccrual loans and $12.4 million in OREO and other nonperforming assets at December 31, 2020. At June 30, 2021 and December 31, 2020, there were $2.4 million and $2.5 million, respectively, of troubled debt restructurings, all of which were accruing as of the restructured date and remain on accrual status.

Section 4013 of the CARES Act and bank regulatory interagency guidance gave entities temporary relief from the accounting and disclosure requirements for TDRs indicating that a lender could conclude that the modifications are not a troubled debt restructuring if the borrower was less than 30 days past due as of December 31, 2019. We have followed the guidance under the CARES Act and the interagency guidance related to these loan modifications. At June 30, 2021, we had approximately $817.4 million in loans modified under Section 4013 of the CARES Act, compared to approximately $825.6 million at December 31, 2020.

Allowance for Credit Losses on Loans (allowance). On January 1, 2020, we adopted FASB ASU 2016-13, which introduced the current expected credit losses (CECL) methodology and required us to estimate all expected credit losses over the remaining life of our loan portfolio. Accordingly, the allowance for credit losses represents an amount that, in management's evaluation, is adequate to provide coverage for all expected future credit losses on outstanding loans. As of June 30, 2021 and December 31, 2020, our allowance for credit losses was approximately $273.7 million and $285.1 million, respectively, which our management believed to be adequate at each of the respective dates. Our allowance for credit losses as a percentage of total loans, inclusive of PPP loans, was 1.20% at June 30, 2021, down from 1.27% at December 31, 2020. No allowance for credit losses has been recorded for PPP loans as they are fully guaranteed by the SBA.

Table of Contents

The decrease in the allowance for credit losses is largely the result of the improvements in the macroeconomic forecast. Our CECL models rely largely on recent historical and projected future macroeconomic conditions to estimate future credit losses. Macroeconomic factors used in the model include the national unemployment rate, gross domestic product, the commercial real estate price index and certain U.S. Treasury interest rates. Projections of these macroeconomic factors, obtained from an independent third party, are utilized to predict quarterly rates of default. These macroeconomic factors experienced significant deterioration during the first six months of 2020, resulting in a significant increase in our allowance for credit losses during the same period. Though these factors improved during the second half of 2020 and through the first two quarters of 2021 resulting in a reduction in the level of our allowance, should they deteriorate in future periods our modeling may require increased levels of provision expense over those recorded during the three and six months ended June 30, 2021.

Under the CECL methodology the allowance for credit losses is measured on a collective basis for pools of loans with similar risk characteristics, and for loans that do not share similar risk characteristics with the collectively evaluated pools, evaluations are performed on an individual basis. Losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable period losses are reverted to long term historical averages. At June 30, 2021, reasonable and supportable periods of 18 months were utilized for all loan segments followed by a 12 month straight line reversion period to long term averages.

The following table sets forth, based on management's estimate, the allocation of the allowance for credit losses to categories of loans as of June 30, 2021 and December 31, 2020 and the percentage of loans in each category to total loans (in thousands):

Pinnacle Financial's management assesses the adequacy of the allowance on a quarterly basis. This assessment includes procedures to estimate the allowance and test the adequacy and appropriateness of the resulting balance. The level of the allowance is based upon management's evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay the loan (including the timing of future payments), the estimated value of any underlying collateral, composition of the loan portfolio, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off. Based upon our evaluation of the loan portfolio, we believe the allowance for credit losses to be adequate to absorb our estimate of expected future     credit losses on loans outstanding at June 30, 2021. While our policies and procedures used to estimate the allowance for credit losses as well as the resultant provision for credit 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 a particular industry or borrower which may negatively impact, materially, our asset quality and the adequacy of our allowance for credit losses and, thus, the resulting provision for credit losses. In particular, if the strict social distancing practices or safer-at-home directives that were initially implemented in response to the spread of COVID-19 were to return in the markets in which we operate or additional variants of the virus become more wide-spread, these impacts could be more severe than currently anticipated.

Investments.  Our investment portfolio, consisting primarily of Federal agency bonds, mortgage-backed securities, and state and municipal securities amounted to $5.3 billion and $4.6 billion at June 30, 2021 and December 31, 2020, respectively. Our investment portfolio serves many purposes including serving as a stable source of income, as collateral for public funds deposits and as a potential liquidity source. A summary of our investment portfolio at June 30, 2021 and December 31, 2020 follows:

	June 30, 2021	December 31, 2020
Weighted average life	6.56 years	6.51 years
Effective duration*	4.29%	4.35%
Tax equivalent yield	2.25%	2.28%

(*) The metric is presented net of fair value hedges tied to certain investment portfolio holdings. The effective duration of the investment portfolio without the fair value hedges as of June 30, 2021 and December 31, 2020 was 5.54% and 5.45%, respectively.

Restricted Cash. Our restricted cash balances totaled approximately $155.3 million at June 30, 2021, compared to $223.8 million at December 31, 2020. This restricted cash is maintained at other financial institutions as collateral primarily for our derivative portfolio. The decrease in restricted cash is attributable primarily to a decrease in collateral requirements on certain derivative instruments for which the fair value has increased. See Note 8. Derivative Instruments in the Notes to our Consolidated Financial Statements elsewhere in this Form 10-Q.

Securities Purchased with Agreement to Resell. At June 30, 2021 we had $500.0 million in securities purchased in agreement to resell. This balance is the result of repurchase agreement transactions with financial institution counterparties. These investments deploy some of our liquidity position into an instrument that improves the return on those funds in the current low rate environment. Additionally, we believe it positions us more favorably for a potential rising interest rate environment in the future. During the three and six months ended June 30, 3021, we purchased $50.0 million and $500.0 million, respectively, of these types of securities. No securities were purchased with agreement to resell prior to 2021.

Deposits and Other Borrowings. We had approximately $28.2 billion of deposits at June 30, 2021 compared to $27.7 billion at December 31, 2020. Our deposits consist of noninterest and interest-bearing demand accounts, savings accounts, money market accounts and time deposits. Additionally, we routinely enter into agreements with certain customers to sell certain securities under agreements to repurchase the security the following day. These agreements (which are typically associated with comprehensive treasury management programs for our clients and provide them with short-term returns for their excess funds) amounted to $177.7 million at June 30, 2021 and $128.2 million at December 31, 2020. Additionally, at June 30, 2021 and December 31, 2020, Pinnacle Bank had borrowed $888.3 million and $1.1 billion, respectively, in advances from the Federal Home Loan Bank of Cincinnati (FHLB). At June 30, 2021, Pinnacle Bank had approximately $3.0 billion in additional availability with the FHLB; however, incremental borrowings are subject to applicable collateral requirements and are made in a formal request by Pinnacle Bank and the subsequent approval by the FHLB.

Generally, we have classified our funding base as either core funding or noncore funding as shown in the table below. The following table represents the balances of our deposits and other funding and the percentage of each type to the total at June 30, 2021 and December 31, 2020:

	June 30, 2021		Percent	December 31, 2020		Percent

Totals	$	29,955,562	100.0%	$	29,592,241	100.0%

(1)The reciprocating categories consists of deposits we receive from a bank network (the Promontory network) in connection with deposits of our customers in excess of our FDIC coverage limit that we place with the Promontory network.

As noted in the table above, our core funding as a percentage of total funding increased from 79.5% at December 31, 2020 to 86.3% at June 30, 2021, primarily as a result of the significant increase in deposits estimated to have been funded, in part, by PPP loans and other government stimulus payments, and our release of wholesale funding that was intentionally acquired to build on-balance sheet liquidity as we prepared for the initial impact of the COVID-19 pandemic but that we began releasing in the first six months of 2021 based on our view of then current market conditions. Competition for core deposits in our markets remains very competitive and we continue to anticipate that our percentage of non-core funding is likely to increase as PPP loan funds and stimulus monies are utilized.

When wholesale funding is necessary to complement the company's core deposit base, management determines which source is best suited to address both liquidity risk management and interest rate risk management objectives. Our Asset Liability Management Policy imposes limitations on overall wholesale funding reliance and on brokered deposit exposure specifically. Both our overall reliance on wholesale funding and exposure to brokered deposits and brokered time deposits were within those policy limitations as of June 30, 2021.

Our funding policies impose limits on the amount of non-core funding we can utilize based on the non-core funding dependency ratio which is calculated pursuant to regulatory guidelines. Periodically, we may exceed our policy limitations, at which time management will develop plans to bring our funding sources back into compliance with our core funding ratios. At June 30, 2021 and December 31, 2020, we were in compliance with our core funding policies. Though growing our core deposit base is a key strategic objective of our firm and we experienced meaningful growth in core deposits in the first six months of 2021, we may increase our non-core funding amounts from current levels if we need to do so to fund growth or increase levels of on-balance sheet liquidity, but we do not currently anticipate that such increases will exceed the limits we have established in our internal policies for total levels of non-core funding.

Subordinated debt and other borrowings.  We have established, or through acquisition acquired, twelve statutory business trusts which were established to issue 30-year trust preferred securities and certain other subordinated debt agreements. These securities qualify as Tier 2 capital subject to annual phase outs beginning five years from maturity. On April 22, 2020, we established a credit facility with the Federal Reserve Bank in conjunction with the PPP, with available borrowing capacity equal to the outstanding balance of PPP loans, which totaled approximately $1.4 billion at June 30, 2021. There were no amounts outstanding under this facility at June 30, 2021. These instruments are outlined below (in thousands):

the $120.0 million aggregate principal amount of subordinated notes issued by Pinnacle Financial listed in the table above later this year when they first become eligible for redemption. The redemption of the Pinnacle Financial subordinated notes is subject to receipt of any required regulatory permissions and our ultimate determination to redeem such notes. Pinnacle Financial is under no obligation to redeem these subordinated notes.

Capital Resources. At June 30, 2021, our shareholders' equity amounted to $5.1 billion compared to $4.9 billion at December 31, 2020. During the second quarter of 2020, we issued 9.0 million depositary shares, each representing a 1/40th interest in a share of Series B Preferred Stock with a liquidation preference of $1,000 per share of Series B Preferred Stock in a registered public offering to both retail and institutional investors. Net proceeds from the transaction after underwriting discounts and offering costs were approximately $217.1 million. The net proceeds were initially retained by Pinnacle Financial and the remaining net proceeds are available to support our obligations including payments related to our outstanding indebtedness and dividend payments on the Series B Preferred Stock, to support the capital needs of our company and our bank, and for other general corporate purposes. For additional information regarding our capital and shareholders’ equity, see Note 10. Regulatory Matters in the Notes to our Consolidated Financial Statements elsewhere in this Form 10-Q.

Share Repurchase Program. During the quarter ended March 31, 2020, we repurchased approximately 1.0 million shares of our common stock at an aggregate cost of $50.8 million under our previously authorized share repurchase agreement. Our last purchase of shares of our common stock under the prior share repurchase program occurred on March 19, 2020, as we suspended the program due to uncertainty surrounding the COVID-19 pandemic and it remained suspended until its expiration on December 31, 2020. On January 19, 2021, our board of directors authorized a new share repurchase program for up to $125.0 million of our outstanding common stock. The authorization for this program will remain in effect through March 31, 2022. We purchased no shares under our current program in the first six months of 2021.

Dividends. Pursuant to Tennessee banking law, our bank may not, without the prior consent of the Commissioner of the TDFI, pay any dividends to us in a calendar year in excess of the total of our bank's retained net profits for that year plus the retained net profits for the preceding two years, which was $681.9 million at June 30, 2021. During the six months ended June 30, 2021, the bank paid dividends of $23.3 million to us which is within the limits allowed by the TDFI.

During the three and six months ended June 30, 2021, we paid $13.9 million and $27.8 million, respectively, in dividends to our common shareholders and $3.8 million and $7.6 million, respectively, in dividends on our Series B Preferred Stock. On July 20, 2021, our board of directors declared a $0.18 per share quarterly cash dividend to common shareholders which should approximate $14.0 million in aggregate dividend payments that are expected to be paid on Aug. 27, 2021 to common shareholders of record as of the close of business on Aug. 6, 2021. Additionally, on that same day, our board of directors approved a quarterly dividend of approximately $3.8 million, or $16.88 per share (or $0.422 per depositary share), on the Series B Preferred Stock payable on Sept. 1, 2021 to shareholders of record at the close of business on Aug. 17, 2021. The amount and timing of all future dividend payments, if any, is subject to board discretion and will depend on our earnings, capital position, financial condition and other factors, including, if necessary, our receipt of dividends from Pinnacle Bank, regulatory capital requirements, as they become known to us and receipt of any regulatory approvals that may become required as a result of our and our bank subsidiary's financial results.

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.  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.  Measurements which we use to help us manage interest rate sensitivity include an earnings simulation model and an economic value of equity (EVE) model. 

Our interest rate sensitivity modeling incorporates a number of assumptions for both earnings simulation and EVE, including loan and deposit re-pricing characteristics, the rate of loan prepayments, etc. ALCO periodically reviews these assumptions for accuracy based on historical data and future expectations. Our ALCO policy requires that the base scenario assumes rates remain flat and is the scenario to which all others are compared in order to measure the change in net interest income and EVE. Policy limits are applied to the results of certain modeling scenarios. While the primary policy scenarios focus is on a twelve month time frame for the earnings simulations model, longer time horizons are also modeled. All policy scenarios assume a static volume forecast where the balance sheet is held constant, although other scenarios are modeled.

Table of Contents

Earnings simulation model. We believe interest rate risk is best measured by our earnings simulation modeling. Earning assets, interest-bearing liabilities and off-balance sheet financial instruments are combined with forecasts of interest rates for the next 12 months and are combined with other factors in order to produce various earnings simulations over that same 12-month period. To limit interest rate risk, we have policy guidelines for our earnings at risk which seek to limit the variance of net interest income in both gradual and instantaneous changes to interest rates. For instantaneous upward and downward changes in rates from management's flat interest rate forecast over the next twelve months, assuming a static balance sheet, the following estimated changes are calculated:

	Estimated % Change in Net Interest Income Over 12 Months
	June 30, 2021*
Instantaneous Rate Change
100 bps increase	1.9	%
200 bps increase	4.9	%
100 bps decrease	(2.1	%)

*: Negative interest rates are not contemplated in these scenarios. The Treasury curve and all short-term rate indices, such as Fed Funds, LIBOR, etc., are assumed to be zero bound.

While an instantaneous shift in interest rates was used in this analysis to provide an estimate of exposure under these scenarios, we believe that a gradual shift in interest rates would have a more modest impact. Further, the earnings simulation model does not take into account factors such as future balance sheet growth, changes in product mix, changes in yield curve relationships, hedging activities we might take and changing product spreads that could mitigate any potential adverse impact of changes in interest rates.

The behavior of our deposit portfolio in the baseline forecast and in alternate interest rate scenarios set out in the table above is a key assumption in our projected estimates of net interest income. The projected impact on net interest income in the table above assumes no change in deposit portfolio size or mix from the baseline forecast in alternative rate environments. In higher rate scenarios, any customer activity resulting in the replacement of low-cost or noninterest-bearing deposits with higher-yielding deposits or market-based funding would reduce the assumed benefit of those deposits. The projected impact on net interest income in the table above also assumes a "through-the-cycle" non-maturity deposit beta which may not be an accurate predictor of actual deposit rate changes realized in scenarios of smaller and/or non-parallel interest rate movements.

At June 30, 2021, our earnings simulation model indicated we were in compliance with our policies for interest rate scenarios for which we model as required by our board approved Asset Liability Policy.  

Economic value of equity model. While earnings simulation modeling attempts to determine the impact of a changing rate environment to our net interest income, our EVE model measures estimated changes to the economic values of our assets, liabilities and off-balance sheet items 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 EVE. We then shock rates as prescribed by our Asset Liability Policy and measure the sensitivity in EVE values for each of those shocked rate scenarios versus the base case. The Asset Liability Policy sets limits for those sensitivities. At June 30, 2021, our EVE modeling calculated the following estimated changes in EVE due to instantaneous upward and downward changes in rates:

	June 30, 2021*
Instantaneous Rate Change
100 bps increase	(1.3	%)
200 bps increase	(5.7	%)
100 bps decrease	(7.7	%)

*: Negative interest rates are not contemplated in these scenarios. The Treasury curve and all short-term rate indices, such as Fed Funds, LIBOR, etc., are assumed to be zero bound.

While an instantaneous shift in interest rates was used in this analysis to provide an estimate of exposure under these scenarios, we believe that a gradual shift in interest rates would have a more modest impact. Since EVE measures the discounted present value of cash flows over the estimated lives of instruments, the change in EVE does not directly correlate to the degree that earnings would be impacted over a shorter time horizon (i.e., the current year). Further, EVE does not take into account factors such as future balance sheet growth, changes in product mix, changes in yield curve relationships, hedging activities we might take and changing product spreads that could mitigate the adverse impact of changes in interest rates.

At June 30, 2021, our EVE model indicated we were in compliance with our policies for all interest rate scenarios for which we model as required by our board approved Asset Liability Policy.

Most likely earnings simulation models. We also analyze a most-likely earnings simulation scenario that projects the expected change in rates based on a forward yield curve adopted by management using expected balance sheet volumes forecasted by

Table of Contents

management.  Separate growth assumptions are developed for loans, investments, deposits, etc.  Other interest rate scenarios analyzed by management may include delayed rate shocks, yield curve steepening or flattening, or other variations in rate movements to further analyze or stress our balance sheet under various interest rate scenarios. Each scenario is evaluated by management. These processes assist management to better anticipate our financial results and, as a result, management may determine the need to invest in other operating strategies and tactics which might enhance results or better position our balance sheet to reduce interest rate risk going forward.

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.  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.

Management's model governance, model implementation and model validation processes and controls are subject to review in our regulatory examinations to ensure they are in compliance with the most recent regulatory guidelines and industry and regulatory practices. Management utilizes a respected, sophisticated third party asset liability modeling software to help ensure implementation of management's assumptions into the model are processed as intended in a robust manner. That said, there are numerous assumptions regarding financial instrument behavior that are integrated into the model. The assumptions are formulated by combining observations gleaned from our historical studies of financial instruments and our best estimations of how, if at all, these instruments may behave in the future given changes in economic conditions, technology, etc. These assumptions may prove to be inaccurate. Additionally, given the large number of assumptions built into our asset liability modeling software, it is difficult, at best, to compare our results to other firms.

ALCO may determine that Pinnacle Financial should over time become more or less asset or liability sensitive depending on the underlying balance sheet circumstances and our conclusions as to anticipated interest rate fluctuations in future periods.  At present, ALCO has determined that its "most likely" rate scenario considers no change in short-term interest rates throughout the remainder of 2021. Our "most likely" rate forecast is based primarily on information we acquire from a service which includes a consensus forecast of numerous interest rate benchmarks. We may implement additional actions designed to achieve our desired sensitivity position which could change from time to time.

We have in the past used, and may in the future continue to use, derivative financial instruments as one tool to manage our interest rate sensitivity, including in our mortgage lending program, while continuing to meet the credit and deposit needs of our customers. For further details on the derivatives we currently use, see Note 8. Derivative Instruments in the Notes to our Consolidated Financial Statements elsewhere in this Form 10-Q.

We may also enter into interest rate swaps to facilitate customer transactions and meet their financing needs.  These swaps qualify as derivatives, even though they are not designated as hedging instruments.

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.

To assist in determining the adequacy of our liquidity, we perform a variety of liquidity stress tests including idiosyncratic, systemic and combined scenarios for both moderate and severe events. Liquidity is defined as the ability to convert assets into cash or cash equivalents without significant loss and to raise additional funds by increasing liabilities. Liquidity management involves maintaining our ability to meet the daily cash flow requirements of our customers, both depositors and borrowers. We seek to maintain a sufficiently liquid asset balance to ensure our ability to meet our obligations. The amount of the appropriate minimum liquid asset balance is determined through severe liquidity stress testing as measured by our liquidity coverage ratio calculation. At June 30, 2021, we were in compliance with our internal policies related to liquidity coverage ratio.

Changes in interest rates also affect our liquidity position. We currently price deposits in response to market rates. If deposits are not priced in response to market rates, a loss of deposits, particularly noncore 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 and competition. 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.

In addition, our bank is a member of the FHLB Cincinnati.  As a result, our bank receives advances from the FHLB Cincinnati, pursuant to the terms of various borrowing agreements, which support our funding needs. Under the borrowing agreements with the FHLB Cincinnati, our bank has pledged certain qualifying residential mortgage loans and, pursuant to a blanket lien, all qualifying commercial mortgage loans as collateral. As such, Pinnacle Bank may use the FHLB Cincinnati as a source of liquidity depending on its ALCO strategies. Additionally, we may pledge additional qualifying assets, reduce the amount of pledged assets or experience changes in the value of pledged assets with the FHLB Cincinnati to increase or decrease our borrowing capacity with the FHLB Cincinnati. At June 30, 2021, we estimate we had approximately $3.0 billion in additional borrowing capacity with the FHLB Cincinnati. However, incremental borrowings are made via a formal request by Pinnacle Bank and the subsequent approval by the FHLB Cincinnati. At June 30, 2021, our bank had received advances from the FHLB Cincinnati totaling $888.3 million. At June 30, 2021, the scheduled maturities of Pinnacle Bank's FHLB Cincinnati advances and interest rates are as follows (in thousands):

Scheduled Maturities	Amount		Interest Rates (1)
2021	$	—	—%
2022	—		—%
2023	—		—%
2024	—		—%
2025	116,250		0.60%
Thereafter	775,013		2.15%
	891,263
Deferred costs	(2,959)
Total Federal Home Loan Bank advances	$	888,304
Weighted average interest rate			1.94%

(1)Some FHLB Cincinnati advances include variable interest rates and could increase in the future.  The table reflects rates in effect as of June 30, 2021.

Pinnacle Bank also has accommodations with upstream correspondent banks available for unsecured short-term advances which aggregate $195 million. These accommodations have various covenants related to their term and availability, and in most cases must be repaid within a month of borrowing. We had no outstanding borrowings at June 30, 2021 under these agreements. Our bank also had approximately $2.7 billion in available Federal Reserve discount window lines of credit at June 30, 2021.

At June 30, 2021, excluding reciprocating time and money market deposits issued through the Promontory Network, we had $1.7 billion of brokered deposits. Historically, we have issued brokered certificates of deposit through several different brokerage houses based on competitive bid. During 2020, and in response to the uncertainty resulting from the COVID-19 pandemic, we intentionally increased our levels of on-balance sheet liquidity. During the first quarter of 2020, this increase was funded by a combination of increased core deposits, increased borrowings from the FHLB Cincinnati and increases in brokered time deposits. Core deposit growth during the remainder of 2020 and through the first half of 2021 increased such that we were able to prepay certain wholesale maturities during the first six months of 2021 while maintaining an appropriate level of on-balance sheet liquidity. We intend to continue to prepay and/or let mature wholesale funding as core deposit growth allows over the next couple of quarters.

During the second quarter of 2021, we announced our intention to move our corporate headquarters to a newly announced office tower in Nashville, where we will be a founding partner and sponsor of the project. This move is currently planned for 2025 and will impact equipment and occupancy costs as we plan for this move. Additionally, we believe the number of our locations, including non-branch locations, will increase over an extended period of time across our footprint and that certain of our locations will be in need of required renovations. In future periods, these expansions and renovation projects may lead to additional equipment and occupancy expenses as well as related increases in salaries and benefits expense. Additionally, we expect we will continue to incur costs associated with technology improvements to enhance the infrastructure of our firm.

Off-Balance Sheet Arrangements.  At June 30, 2021, we had outstanding standby letters of credit of $243.8 million and unfunded loan commitments outstanding of $10.6 billion. Because these commitments generally have fixed expiration dates and many will expire

without being drawn upon, the total commitment level does not necessarily represent future cash requirements. If needed to fund these outstanding commitments, Pinnacle Bank has the ability to liquidate Federal funds sold or, on a short-term basis, to borrow and purchase Federal funds from other financial institutions.

Impact of Inflation

The consolidated financial statements and related consolidated financial data presented herein have been prepared in accordance with U.S. GAAP and practices within the banking industry which require the measurement of financial position and operating results in terms of historical dollars without considering the changes in the relative purchasing power of money over time due to inflation. Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates have a more significant impact on a financial institution's performance than the effects of general levels of inflation.

______________________

(1)During the quarter ended June 30, 2021, 28,256 shares of restricted stock or performance-based vesting restricted stock units previously awarded to certain of the participants in our equity incentive plans vested. We withheld 8,359 shares of common stock to satisfy tax withholding requirements associated with the vesting of these awards.

(2)On January 19, 2021, the board of directors authorized a share repurchase program for up to $125.0 million of Pinnacle Financial's outstanding common stock. The share repurchase program is set to expire on March 31, 2022. Share repurchases may be made from time to time, on the open market or in privately negotiated transactions, at the discretion of the management of Pinnacle Financial, after the board of directors of Pinnacle Financial authorizes a repurchase program. The approved share repurchase program does not obligate Pinnacle Financial to repurchase any dollar amount or number of shares, and the program may be extended, modified, suspended, or discontinued at any time. Stock repurchases generally are affected through open market purchases, and may be made through unsolicited negotiated transactions. The timing of these repurchases will depend on market conditions and other requirements. Pinnacle Financial did not repurchase any shares of its common stock under its current repurchase plan during the six months ended June 30, 2021.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 1. Summary of Significant Accounting Policies

Nature of Business — Pinnacle Financial Partners, Inc. (Pinnacle Financial) is a financial holding company whose primary business is conducted by its wholly-owned subsidiary, Pinnacle Bank. Pinnacle Bank is a commercial bank headquartered in Nashville, Tennessee. Pinnacle Financial completed its acquisitions of CapitalMark Bank & Trust (CapitalMark), Magna Bank (Magna), Avenue Financial Holdings, Inc. (Avenue), BNC Bancorp (BNC) and Advocate Capital, Inc. (Advocate Capital) on July 31, 2015, September 1, 2015, July 1, 2016, June 16, 2017 and July 2, 2019, respectively. Pinnacle Financial and Pinnacle Bank also collectively hold a 49% interest in Bankers Healthcare Group, LLC (BHG), a company that primarily serves as a full-service commercial loan provider to healthcare and other professional practices. Pinnacle Bank provides a full range of banking services, including investment, mortgage, insurance, and comprehensive wealth management services, in its 14 primarily urban markets across the Southeast.

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. generally accepted accounting principles (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 the consolidated financial statements and related notes appearing in Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2020 (2020 10-K).

These consolidated financial statements include the accounts of Pinnacle Financial and its wholly-owned subsidiaries. Certain statutory trust affiliates of Pinnacle Financial, as noted in Note 11. Other Borrowings are included in these consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminated in consolidation.

Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date 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 include the determination of the allowance for credit losses and determination of any impairment of goodwill or intangible assets. It is reasonably possible Pinnacle Financial's estimate of the allowance for credit losses and determination of impairment of goodwill or intangible assets could change as a result of the continued impact of the COVID-19 pandemic on the economy. The resulting change in these estimates could be material to Pinnacle Financial's consolidated financial statements. There have been no significant changes to Pinnacle Financial's significant accounting policies as disclosed in the 2020 10-K.

Cash Flow Information — Supplemental cash flow information addressing certain cash and noncash transactions for the six months ended June 30, 2021 and 2020 was as follows (in thousands):

	For the six months ended June 30,
	2021		2020
Cash Transactions:
Interest paid	$	63,683	$	127,807
Income taxes paid, net	56,073		23,749
Operating lease payments	7,133		6,750
Noncash Transactions:
Loans charged-off to the allowance for credit losses	27,029		20,695
Loans foreclosed upon and transferred to other real estate owned	620		2,442
Loans foreclosed upon and transferred to other assets	—		25
Available-for-sale securities transferred to held-to-maturity portfolio	—		873,613
Right-of-use asset recognized during the period in exchange for lease obligations	4,771		2,928

Income Per Common Share — Basic net income per common share (EPS) is computed by dividing net income available to common shareholders by the weighted average common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The difference between basic and diluted weighted average common shares outstanding is attributable to common stock options, restricted share awards, and restricted share unit awards. The dilutive effect of outstanding options, restricted share awards, and restricted share unit awards is reflected in diluted EPS by application of the treasury stock method.

Recently Adopted Accounting Pronouncements — In January 2020, the FASB issued Accounting Standards Update 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. These amendments, among other things, clarify that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, Investments-Equity Method and Joint Ventures, for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments also clarify that when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. An entity should apply ASU 2020-01 prospectively at the beginning of the interim period that includes the adoption date. The amendments became effective for Pinnacle Financial on January 1, 2021 and had no impact on Pinnacle Financial's consolidated financial statements.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes to simplify various aspects of the current guidance to promote consistent application of the standard among reporting entities by moving certain exceptions to the general principles. The amendments are effective for fiscal years beginning after December 15, 2020. The amendments became effective for Pinnacle Financial on January 1, 2021 and had no impact on Pinnacle Financial's consolidated financial statements.

In March 2020, the FASB issued Accounting Standards Update 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and has issued subsequent amendments thereto, which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. Pinnacle Financial is implementing a transition plan to identify and modify its loans and other financial instruments, including certain indebtedness, with attributes that are either directly or indirectly influenced by LIBOR. Pinnacle Financial is assessing ASU 2020-04 and its impact on the transition away from LIBOR for its loans and other financial instruments.

Newly Issued Not Yet Effective Accounting Standards — Other than those pronouncements discussed above which have been recently adopted, Pinnacle Financial does not believe there were any other recently issued accounting pronouncements that are expected to materially impact its consolidated financial statements.

Subsequent Events — ASC Topic 855, Subsequent Events, establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. Pinnacle Financial evaluated all events or transactions that occurred after June 30, 2021 through the date of the issued financial statements. On July 30, 2021, Pinnacle Bank redeemed the $130.0 million aggregate principal amount of subordinated notes as more fully disclosed in Note 11. Other Borrowings. Other than the above-noted redemption, no other subsequent events were noted.

During the quarters ended March 31, 2020 and September 30, 2018, Pinnacle Financial transferred, at fair value, $873.6 million and $179.8 million, respectively, of municipal securities from the available-for-sale portfolio to the held-to-maturity portfolio. The related net unrealized after tax gains of $69.0 million and net unrealized after tax losses of $2.2 million, respectively, remained in accumulated other comprehensive income (loss) and are being amortized over the remaining life of the securities, offsetting the related amortization of discount or premium on the transferred securities. No gains or losses were recognized at the time of the transfer. At June 30, 2021, approximately $676.5 million of securities within Pinnacle Financial's investment portfolio were pledged to secure either public funds and other deposits or securities sold under agreements to repurchase. At June 30, 2021, repurchase agreements comprised of secured borrowings totaled $177.7 million and were secured by $177.7 million of pledged U.S. government agency securities, municipal securities, asset-backed securities, and corporate debentures. As the fair value of securities pledged to secure repurchase agreements may decline, Pinnacle Financial regularly evaluates its need to pledge additional securities to remain adequately secured.

The amortized cost and fair value of debt securities as of June 30, 2021 by contractual maturity are shown below. Actual maturities may differ from contractual maturities of mortgage- and asset-backed securities since the mortgages and assets underlying the securities may be called or prepaid with or without penalty. Therefore, these securities are not included in the maturity categories in the following summary (in thousands):

The applicable dates for determining when securities were in an unrealized loss position were June 30, 2021 and December 31, 2020. As such, it is possible that a security had a market value less than its amortized cost on other days during the past twelve-month periods ended June 30, 2021 and December 31, 2020, but is not in the "Investments with an Unrealized Loss of less than 12 months" category above.

As shown in the tables above, including both available-for-sale and held-to-maturity investment securities, at June 30, 2021, Pinnacle Financial had approximately $14.0 million in unrealized losses on approximately $1.0 billion of securities. The unrealized losses associated with $873.6 million and $179.8 million of municipal securities transferred from the available-for-sale portfolio to the held-to-maturity portfolio during the quarters ended March 31, 2020 and September 30, 2018, respectively, represent unrealized losses since the date of purchase, independent of the impact associated with changes in the cost basis upon transfer between portfolios. For any securities classified as available-for-sale that are in an unrealized loss position at the balance sheet date, Pinnacle Financial assesses whether or not it intends to sell the security, or more likely than not will be required to sell the security, before recovery of its amortized cost basis which would require a write-down to fair value through net income. Because Pinnacle Financial currently does not intend to sell those securities that have an unrealized loss at June 30, 2021, and it is not more-likely-than-not that Pinnacle

Financial will be required to sell the securities before recovery of their amortized cost bases, which may be maturity, Pinnacle Financial has determined that no write-down is necessary. In addition, Pinnacle Financial evaluates whether any portion of the decline in fair value is the result of credit deterioration, which would require the recognition of an allowance for credit losses. Such evaluations consider the extent to which the amortized cost of the security exceeds its fair value, changes in credit ratings and any other known adverse conditions related to the specific security. The unrealized losses associated with securities at June 30, 2021 are driven by changes in interest rates and are not due to the credit quality of the securities, and accordingly, no allowance for credit losses is considered necessary related to available-for-sale securities at June 30, 2021. These securities will continue to be monitored as a part of Pinnacle Financial's ongoing evaluation of credit quality. Management evaluates the financial performance of the issuers on a quarterly basis to determine if it is probable that the issuers can make all contractual principal and interest payments.

The allowance for credit losses on held-to-maturity securities is measured on a collective basis by major security type. At June 30, 2021, Pinnacle Financial's held-to-maturity securities consist entirely of municipal securities. The estimates of expected credit losses are based on historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. A reasonable and supportable period of 18 months and reversion period of 12 months was utilized to estimate credit losses on held-to-maturity municipal securities at each of June 30, 2021 and 2020. At June 30, 2021 and December 31, 2020, the estimated allowance for credit losses on these securities was $198,000 and $191,000, respectively, with the change driven largely by changes in macroeconomic projections.

Pinnacle Financial utilizes bond credit ratings assigned by third party ratings agencies to monitor the credit quality of debt securities held-to-maturity. At June 30, 2021, all debt securities classified as held-to-maturity were rated A or higher by the ratings agencies. Updated credit ratings are obtained as they become available from the ratings agencies.

Periodically, available-for-sale securities may be sold or the composition of the portfolio realigned to improve yields, quality or marketability, or to implement changes in investment or asset/liability strategy, including maintaining collateral requirements and raising funds for liquidity purposes or preparing for anticipated changes in market interest rates. Additionally, if an available-for-sale security loses its investment grade or tax-exempt status, the underlying credit support is terminated or collection otherwise becomes uncertain based on factors known to management, Pinnacle Financial will consider selling the security, but will review each security on a case-by-case basis as these factors become known. During the six months ended June 30, 2021, $2.2 million of available-for-sale securities were sold and $270,000 related to net gains on sales of available-for-sale securities were reclassified from accumulated other comprehensive income into net income.

Pinnacle Financial has entered into various fair value hedging transactions to mitigate the impact of changing interest rates on the fair values of available for sale securities. See Note 8. Derivative Instruments for disclosure of the gains and losses recognized on derivative instruments and the cumulative fair value hedging adjustments to the carrying amount of the hedged securities.

Loans and Allowance for Credit Losses

Receivables [Abstract]

Loans and Allowance for Credit Losses

Note 4. Loans and Allowance for Credit Losses

For financial reporting purposes, Pinnacle Financial classifies its loan portfolio based on the underlying collateral utilized to secure each loan. This classification is consistent with those utilized in the Quarterly Report of Condition and Income filed by Pinnacle Bank with the Federal Deposit Insurance Corporation (FDIC).

Pinnacle Financial uses the following loan categories for presentation of loan balances and the related allowance for credit losses on loans:

•Owner occupied commercial real estate mortgage loans - Owner occupied commercial real estate mortgage loans are secured by commercial office buildings, industrial buildings, warehouses or retail buildings where the owner of the building occupies the property. For such loans, repayment is largely dependent upon the operation of the borrower's business.

•Non-owner occupied commercial real estate loans - These loans represent investment real estate loans secured by office buildings, industrial buildings, warehouses, retail buildings, and multifamily residential housing. Repayment is primarily dependent on lease income generated from the underlying collateral.

•Consumer real estate mortgage loans - Consumer real estate mortgage consists primarily of loans secured by 1-4 family residential properties, including home equity lines of credit. Repayment is primarily dependent on the personal cash flow of the borrower.

•Construction and land development loans - Construction and land development loans include loans where the repayment is dependent on the successful completion and eventual sale, refinance or operation of the related real estate project. Construction and land development loans include 1-4 family construction projects and commercial construction endeavors such as warehouses, apartments, office and retail space and land acquisition and development.

•Commercial and industrial loans - Commercial and industrial loans include loans to business enterprises issued for commercial, industrial and/or other professional purposes. These loans are generally secured by equipment, inventory, and accounts receivable of the borrower and repayment is primarily dependent on business cash flows. Loans totaling $1.4 billion and $1.8 billion granted under the Paycheck Protection Program are included in this category as of June 30, 2021, and December 31, 2020, respectively.

•Consumer and other loans - Consumer and other loans include all loans issued to individuals not included in the consumer real estate mortgage classification. Examples of consumer and other loans are automobile loans, consumer credit cards and loans to finance education, among others. Many consumer loans are unsecured. Repayment is primarily dependent on the personal cash flow of the borrower.

Loans at June 30, 2021 and December 31, 2020 were as follows:

	June 30, 2021		December 31, 2020
Commercial real estate:
Owner occupied	$	2,817,689	$	2,802,227
Non-owner occupied	5,368,804		5,203,384
Consumer real estate – mortgage	3,335,537		3,099,172
Construction and land development	2,791,611		2,901,746
Commercial and industrial	8,144,170		8,038,457
Consumer and other	440,124		379,515
Subtotal	$	22,897,935	$	22,424,501
Allowance for credit losses	(273,747)		(285,050)
Loans, net	$	22,624,188	$	22,139,451

Commercial loans receive risk ratings assigned by a financial advisor subject to validation by Pinnacle Financial's independent loan review department. Risk ratings are categorized as pass, special mention, substandard, substandard-nonaccrual or doubtful-nonaccrual. Pass rated loans include multiple ratings categories representing varying degrees of risk attributes lesser than those of the other defined risk categories further described below. Pinnacle Financial believes its categories follow those used by Pinnacle Bank's primary regulators. At June 30, 2021, approximately 76.5% of Pinnacle Financial's loan portfolio was analyzed as a commercial loan type with a specifically assigned risk rating. Consumer loans and small business loans are generally not assigned an individual risk rating but are evaluated as either accrual or nonaccrual based on the performance of the individual loans. However, certain consumer real estate-mortgage loans and certain consumer and other loans receive a specific risk rating due to the loan proceeds being used for commercial purposes even though the collateral may be of a consumer loan nature. Consumer loans that have been placed on nonaccrual but have not otherwise been assigned a risk rating are believed by management to share risk characteristics with loans rated substandard-nonaccrual and have been presented as such in Pinnacle Financial's risk rating disclosures.

Risk ratings are subject to continual review by a financial advisor and a senior credit officer. At least annually, Pinnacle Financial's credit procedures require every risk rated loan of $1.0 million or more be subject to a formal credit risk review process. Each loan's risk rating is also subject to review by Pinnacle Financial's independent loan review department, which reviews a substantial portion of Pinnacle Financial's risk rated portfolio annually. Included in the coverage are independent reviews of loans in targeted higher-risk portfolio segments such as certain commercial and industrial loans, land loans and/or loan types in certain geographies. Substantial credit risk review procedures have been performed to assess the impacts of the COVID-19 pandemic on the loan portfolio, and the results of these procedures are reflected in Pinnacle Financial's risk rating disclosures as of June 30, 2021.

Following are the definitions of the risk rating categories used by Pinnacle Financial. Pass rated loans include all credits other than those included within these categories:

•Special mention loans have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in Pinnacle Financial's credit position at some future date.

•Substandard loans are inadequately protected by the current net worth and financial capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize collection of the debt. Substandard loans are characterized by the distinct possibility that Pinnacle Financial could sustain some loss if the deficiencies are not corrected.

•Substandard-nonaccrual loans are substandard loans that have been placed on nonaccrual status.

•Doubtful-nonaccrual loans have all the characteristics of substandard-nonaccrual loans 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 table below presents loan balances classified within each risk rating category by primary loan type and based on year of origination or most recent renewal as of June 30, 2021 (in thousands):

(1) Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have doubts about the borrower's ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators for loans classified as substandard, excluding troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $169.3 million at June 30, 2021, compared to $173.5 million at December 31, 2020.

The adequacy of the allowance for credit losses is reviewed by Pinnacle Financial's management on a quarterly basis. This assessment includes procedures to estimate the allowance and test the adequacy and appropriateness of the resulting balance. The level of the allowance is based upon management's evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay the loan (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. The level of the allowance for credit losses maintained by management is believed adequate to absorb all expected future losses inherent in the loan portfolio at the balance sheet date. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off.

Pinnacle Financial adopted ASU 2016-13 on January 1, 2020, which introduced the CECL methodology for estimating all expected losses over the life of a financial asset. Under the CECL methodology the allowance for credit losses is measured on a collective basis for pools of loans with similar risk characteristics, and for loans that do not share similar risk characteristics with the collectively evaluated pools, evaluations are performed on an individual basis. Upon adoption of ASU 2016-13 in 2020, the opening balance of the allowance for credit losses was increased by $38.1 million through retained earnings.

For commercial real estate, consumer real estate, construction and land development, and commercial and industrial loans, Pinnacle Financial primarily utilizes a probability of default and loss given default modeling approach. These models utilize historical correlations between default experience and certain macroeconomic factors as determined through a statistical regression analysis. All loan segments modeled using this approach consider changes in the national unemployment rate. In addition to the national unemployment rate, GDP and the three month treasury rate are considered for owner occupied commercial real estate, the commercial real estate price index and the five year treasury rate are considered for construction loans, and the three month treasury rate is considered for commercial and industrial loans. For the consumer and other loan segment, a non-statistical approach based on historical charge off rates is utilized.

Losses are predicted over a period of time determined to be reasonable and supportable, and at the end of the reasonable and supportable period losses are reverted to long term historical averages. The reasonable and supportable period and reversion period are re-evaluated each quarter by Pinnacle Financial and are dependent on the current economic environment among other factors. At June 30, 2021 and December 31, 2020, a reasonable and supportable period of 18 months was utilized for all loan segments, followed by a 12 month straight line reversion to long term averages.

The estimated loan losses for all loan segments are adjusted for changes in qualitative factors not inherently considered in the quantitative analyses. These adjustments are based upon quarterly trend assessments in portfolio concentrations, policy exceptions, associate retention, independent loan review results, collateral considerations, risk ratings, competition and peer group credit quality trends. The qualitative allowance allocation, as determined by the processes noted above, is increased or decreased for each loan segment based on the assessment of these various qualitative factors.

Loans that do not share similar risk characteristics with the collectively evaluated pools are evaluated on an individual basis and are excluded from the collectively evaluated pools. Individual evaluations are generally performed for loans greater than $1.0 million which have experienced significant credit deterioration. Such loans are evaluated for credit losses based on either discounted cash flows or the fair value of collateral.

The following table presents the amortized cost basis of collateral dependent loans, which are individually evaluated to determine expected credit losses, as of June 30, 2021 and December 31, 2020 (in thousands):

Pinnacle Financial's policy is the accrual of interest income will be discontinued when (1) there is a significant deterioration in the financial condition of the borrower and full repayment of principal and interest is not expected or (2) the principal or interest is more than 90 days past due, unless the loan is both well secured and in the process of collection. As such, at the date loans are placed on nonaccrual status, Pinnacle Financial reverses all previously accrued interest income against current year earnings. Pinnacle Financial's policy is once a loan is placed on nonaccrual status each subsequent payment is reviewed on a case-by-case basis to determine if the payment should be applied to interest or principal pursuant to regulatory guidelines. Pinnacle Financial recognized no interest income from cash payments received on nonaccrual loans during the three and six months ended June 30, 2021 and 2020, respectively. Had these loans been on accruing status, an additional $776,000 and $1.1 million of interest income would have been recognized for the three and six months ended June 30, 2021 compared to an additional $854,000 and $1.6 million for the three and six months ended June 30, 2020, respectively. Approximately $39.5 million and $51.7 million of nonaccrual loans were performing pursuant to their contractual terms as of June 30, 2021 and December 31, 2020, respectively.

At June 30, 2021 and December 31, 2020, there were $2.4 million and $2.5 million, respectively, of troubled debt restructurings that were performing as of their restructure date and which were accruing interest. Troubled commercial loans are restructured by specialists within Pinnacle Bank's Special Assets Group, and all restructurings are approved by committees and/or credit officers separate and apart from the normal loan approval process. These specialists are charged with reducing Pinnacle Financial's overall risk and exposure to loss in the event of a restructuring by obtaining some or all of the following: improved documentation, additional guaranties, increase in curtailments, reduction in collateral release terms, additional collateral or other similar strategies.

There were no troubled debt restructurings made during the six months ended June 30, 2021. During the six months ended June 30, 2021 and 2020, there were no troubled debt restructurings that subsequently defaulted within twelve months of the restructuring. The following table outlines the amount of each loan category where troubled debt restructurings were made during the six months ended June 30, 2020 (in thousands):

	June 30, 2020
	Number of contracts	Pre Modification Outstanding Recorded Investment		Post Modification Outstanding Recorded Investment, net of related allowance

Pinnacle Financial analyzes its commercial loan portfolio to determine if a concentration of credit risk exists to any industries. Pinnacle Financial utilizes broadly accepted industry classification systems in order to classify borrowers into various industry classifications. Pinnacle Financial has a credit exposure (loans outstanding plus unfunded lines of credit) exceeding 25% of Pinnacle Bank's total risk-based capital to borrowers in the following industries at June 30, 2021 with the comparative exposures for December 31, 2020 (in thousands):

	June 30, 2021
	Outstanding Principal Balances		Unfunded Commitments		Total exposure		Total Exposure at December 31, 2020
Lessors of nonresidential buildings	$	3,587,877	$	1,228,232	$	4,816,109	$	4,442,712
Lessors of residential buildings	1,376,546		887,899		2,264,445		2,126,246
Hotels (except Casino Hotels) and Motels	979,770		65,699		1,045,469		1,039,259
New Housing For-Sale Builders	493,082		814,372		1,307,454		1,124,302

Pinnacle Financial monitors two ratios regarding construction and commercial real estate lending as part of its concentration management processes. Both ratios are calculated by dividing certain types of loan balances for each of the two categories by Pinnacle Bank’s total risk-based capital. At June 30, 2021 and December 31, 2020, Pinnacle Bank’s construction and land development loans as a percentage of total risk-based capital were 80.1% and 89.0%, respectively. Non-owner occupied commercial real estate and multifamily loans (including construction and land development loans) as a percentage of total risk-based capital were 248.8% and 264.0% as of June 30, 2021 and December 31, 2020, respectively. Banking regulations have established guidelines for the construction ratio of less than 100% of total risk-based capital and for the non-owner occupied ratio of less than 300% of total risk-based capital. When a bank’s ratios are in excess of one or both of these guidelines, banking regulations generally require an increased level of monitoring in these lending areas by bank management. At June 30, 2021, Pinnacle Bank was within the 100% and 300% guidelines and has established what it believes to be appropriate controls to monitor its lending in these areas as it aims to keep the level of these loans below the 100% and 300% thresholds.

At June 30, 2021, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $8.8 million to current directors, executive officers, and their related interests, of which $5.4 million had been drawn upon. At December 31, 2020, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $10.7 million to directors, executive officers, and their related interests, of which approximately $6.8 million had been drawn upon. All loans to directors, executive officers, and their related interests were performing in accordance with contractual terms at June 30, 2021 and December 31, 2020.

At June 30, 2021, Pinnacle Financial had approximately $25.8 million in commercial loans held for sale compared to $31.2 million at December 31, 2020, which primarily included commercial real estate and apartment loans originated for sale to a third-party as part of a multi-family loan program. Such loans are closed under a pass-through commitment structure wherein Pinnacle Bank's loan commitment to the borrower is the same as the third party's take-out commitment to Pinnacle Bank and the third party purchase typically occurs within thirty days of Pinnacle Bank closing with the borrowers.

At June 30, 2021, Pinnacle Financial had approximately $37.3 million of mortgage loans held-for-sale compared to approximately $67.8 million at December 31, 2020. Total loan volumes sold during the six months ended June 30, 2021 were approximately $941.3 million compared to approximately $837.4 million for the six months ended June 30, 2020. During the three and six months ended June 30, 2021, Pinnacle Financial recognized $6.7 million and $20.4 million, respectively, in gains on the sale of these loans, net of commissions paid, compared to $19.6 million and $28.2 million, respectively, during the three and six months ended June 30, 2020.

These mortgage loans held-for-sale are originated internally and are primarily to borrowers in Pinnacle Bank's geographic markets. These sales are typically on a mandatory basis to investors that follow conventional government sponsored entities (GSE) and the Department of Housing and Urban Development/U.S. Department of Veterans Affairs (HUD/VA) guidelines.

Each purchaser of a mortgage loan held-for-sale has specific guidelines and criteria for sellers of loans and the risk of credit loss with regard to the principal amount of the loans sold is generally transferred to the purchasers upon sale. While the loans are sold without recourse, the purchase agreements require Pinnacle Bank to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that the loans sold were in breach of these representations or warranties, Pinnacle Bank has obligations to either repurchase the loan for the unpaid principal balance and related investor fees or make the purchaser whole for the economic benefits of the loan. To date, Pinnacle Bank's liability pursuant to the terms of these representations and warranties has been insignificant to Pinnacle Bank.

Income Tax Disclosure [Abstract]

Income Taxes

Note 5. Income Taxes

ASC 740, Income Taxes, defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authority. This section also provides guidance on the derecognition, measurement and classification of income tax uncertainties, along with any related interest and penalties, and includes guidance concerning accounting for income tax uncertainties in interim periods.

The unrecognized tax benefit related to uncertain tax positions related to state income tax filings was $9.7 million at June 30, 2021 and December 31, 2020, respectively. No change was recorded to the unrecognized tax benefit related to uncertain tax positions in each of the three and six month periods ended June 30, 2021 and 2020.

Pinnacle Financial's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. For both the three and six months ended June 30, 2021 and 2020, respectively, there were no interest and penalties recorded in the income statement.

Pinnacle Financial's effective tax rate for the three and six months ended June 30, 2021 was 18.9% and 18.6%, respectively, compared to 15.2% and 9.5%, respectively, for the three and six months ended June 30, 2020. The difference between the effective tax rate and the federal and state income tax statutory rate of 26.14% at June 30, 2021 and 2020 is primarily due to investments in bank qualified municipal securities, tax benefits of Pinnacle Bank's real estate investment trust subsidiary, participation in the Tennessee Community Investment Tax Credit (CITC) program, and tax benefits associated with share-based compensation, bank-owned life insurance and Pinnacle Financial's captive insurance subsidiary, offset in part by the limitation on deductibility of meals and entertainment expense, non-deductible FDIC premiums and non-deductible executive compensation.

Income tax expense is also impacted by the vesting of equity-based awards and the exercise of employee stock options, which expense or benefit is recorded as a discrete item as a component of total income tax, the amount of which is dependent upon the change in the grant date fair value and the vest date fair value of the underlying award. Accordingly, for the three and six months ended June 30, 2021, we recognized excess tax benefits of $302,000 and $1.9 million, respectively, compared to expense of $272,000 and benefits of $590,000, respectively, for the three and six months ended June 30, 2020. For the six months ended June 30, 2020, income tax expense was also meaningfully impacted by provision for credit losses, including provision for credit losses resulting from the COVID-19 pandemic, which was recorded as a discrete item as a component of total income tax and contributed to a tax benefit of $22.4 million for the six months ended June 30, 2020.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

Note 6. Commitments and Contingent Liabilities

In the normal course of business, Pinnacle Financial has entered into off-balance sheet financial instruments which include commitments to extend credit (i.e., including unfunded lines of credit) and standby letters of credit. Commitments to extend credit are usually the result of lines of credit granted to existing borrowers under agreements that the total outstanding indebtedness will not exceed a specific amount during the term of the indebtedness. Typical borrowers are commercial concerns that use lines of credit to supplement their treasury management functions, thus their total outstanding indebtedness may fluctuate during any time period based on the seasonality of their business and the resultant timing of their cash flows. Other typical lines of credit are related to home equity loans granted to consumers. Commitments to extend credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. At June 30, 2021, these commitments amounted to $10.6 billion, of which approximately $1.2 billion related to home equity lines of credit.

Standby letters of credit are generally issued on behalf of an applicant (customer) to a specifically named beneficiary and are the result of a particular business arrangement that exists between the applicant and the beneficiary. Standby letters of credit have fixed expiration dates and are usually for terms of two years or less unless terminated beforehand due to criteria specified in the standby letter of credit. A typical arrangement involves the applicant routinely being indebted to the beneficiary for such items as inventory purchases, insurance, utilities, lease guarantees or other third party commercial transactions. The standby letter of credit would permit the beneficiary to obtain payment from Pinnacle Financial under certain prescribed circumstances. Subsequently, Pinnacle Financial would then seek reimbursement from the applicant pursuant to the terms of the standby letter of credit. At June 30, 2021, these commitments amounted to $243.8 million.

Pinnacle Financial typically follows the same credit policies and underwriting practices when making these commitments as it does for on-balance sheet instruments. Each customer's creditworthiness is typically evaluated on a case-by-case basis, and the amount of collateral obtained, if any, is based on management's credit evaluation of the customer. Collateral held varies but may include cash, real estate and improvements, marketable securities, accounts receivable, inventory, equipment and personal property.

The contractual amounts of these commitments are not reflected in the consolidated financial statements and only amounts drawn upon would be reflected in the future. Since many of the commitments are expected to expire without being drawn upon, the contractual amounts do not necessarily represent future cash requirements. However, should the commitments be drawn upon and should Pinnacle Bank's customers default on their resulting obligation to Pinnacle Bank, the maximum exposure to credit loss, without consideration of collateral, is represented by the contractual amount of those commitments. At June 30, 2021 and December 31, 2020, Pinnacle Financial had accrued $23.2 million for the inherent risks associated with these off-balance sheet commitments.

Various legal claims also arise from time to time in the normal course of business. In the opinion of management, the resolutions of these claims outstanding at June 30, 2021 are not expected to have a material adverse impact on Pinnacle Financial's consolidated financial condition, operating results or cash flows.

Share-based Payment Arrangement [Abstract]

Stock Options and Restricted Shares

Note 7.  Stock Options and Restricted Shares

Pinnacle Financial's Amended and Restated 2018 Omnibus Equity Incentive Plan (the "2018 Plan") permits Pinnacle Financial to reissue outstanding awards that are subsequently forfeited, settled in cash, withheld by Pinnacle Financial to cover withholding taxes or expire unexercised and returned to the 2018 Plan. At June 30, 2021, there were approximately 2.0 million shares available for issuance under the 2018 Plan.

Upon the acquisition of CapitalMark, Pinnacle Financial assumed approximately 858,000 stock options under the CapitalMark Option Plan. No further awards remain available for issuance under the CapitalMark Option Plan. At June 30, 2021, all of the options remaining outstanding under any equity incentive plan of Pinnacle Financial were granted under the CapitalMark Option Plan.

Common Stock Options

A summary of the stock option activity within the equity incentive plans during the six months ended June 30, 2021 and information regarding, contractual terms remaining, intrinsic values and other matters is as follows:

	Number	Weighted-Average Exercise Price		Weighted-Average Contractual Remaining Term (in years)	Aggregate Intrinsic Value (000's)
Outstanding at December 31, 2020	101,769	$	23.46	1.86	$	4,169	(1)

Options exercisable at June 30, 2021	83,495	$	23.63	1.44	$	5,399	(2)

(1)The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of Pinnacle Financial common stock of $64.40 per common share at December 31, 2020 for the 101,769 options that were in-the-money at December 31, 2020.

(2)The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of Pinnacle Financial common stock of $88.29 per common share at June 30, 2021 for the 83,495 options that were in-the-money at June 30, 2021.

Compensation costs related to stock options granted under Pinnacle Financial's equity incentive plans have been fully recognized and all outstanding option awards are fully vested.

Restricted Share Awards

A summary of activity for unvested restricted share awards for the six months ended June 30, 2021 is as follows:

	Number	Grant Date Weighted-Average Cost
Unvested at December 31, 2020	594,669	$	56.97
Shares awarded	200,346
Restrictions lapsed and shares released to associates/directors	(157,734)
Shares forfeited	(24,757)
Unvested at June 30, 2021	612,524	$	62.06

Pinnacle Financial has granted restricted share awards to associates and outside directors with a time-based vesting criteria. Compensation expense associated with time-based vesting restricted share awards is recognized over the time period that the restrictions associated with the awards lapse on a straight-line basis based on the total cost of the award. The following table outlines restricted stock grants that were made, grouped by similar vesting criteria, during the six months ended June 30, 2021. The table reflects the life-to-date activity for these awards:

Grant Year	Group (1)	Vesting Period in years			Shares awarded	Restrictions lapsed and shares released to participants	Shares withheld for taxes by participants	Shares Forfeited by participants (4)	Shares Unvested
Time Based Awards
2021	Associates (2)	3	-	5	188,516	89	60	8,280	180,087
Outside Director Awards (3)
2021	Outside directors			1	11,830	—	—	—	11,830

(1)Groups include employees (referred to as associates above) and outside directors. When the restricted shares are awarded, a participant receives voting rights and forfeitable dividend rights with respect to the shares, but is not able to transfer the shares until the restrictions have lapsed. Once the restrictions lapse, the participant is taxed on the value of the award and may elect to sell some shares (or have Pinnacle Financial withhold some shares) to pay the applicable income taxes associated with the award. Alternatively, the recipient can pay the withholding taxes in cash. For time-based vesting restricted share awards, dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination. For awards to Pinnacle Financial's directors, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.

(2)The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant.

(3)Restricted share awards are issued to the outside members of the board of directors in accordance with their board compensation plan. Restrictions lapse on March 1, 2022 based on each individual board member meeting attendance goals for the various board and board committee meetings to which each member was scheduled to attend.

(4)These shares represent forfeitures resulting from recipients whose employment or board membership was terminated during the year-to-date period ended June 30, 2021. Any dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination or will not be distributed from escrow, as applicable.

Restricted Stock Unit Awards

In 2021, Pinnacle Financial granted restricted stock units to its Named Executive Officers (NEOs) and leadership team members with time-based vesting criteria. Compensation expense associated with time-based vesting restricted stock unit awards is recognized over the time period that the restrictions associated with the awards lapse on a straight-line basis based on the total cost of the award. The following table outlines restricted stock unit grants that were made, grouped by similar vesting criteria, during the six months ended June 30, 2021. The table reflects the life-to-date activity for these awards:

Grant Year	Vesting Period in years	Shares awarded	Restrictions lapsed and shares released to participants	Shares withheld for taxes by participants	Shares Forfeited by participants (1)	Shares Unvested
2021	3	56,864	89	39	368	56,368

(1)These shares represent forfeitures resulting from recipients whose employment was terminated during the year-to-date period ended June 30, 2021. Dividend equivalents are held in escrow for award recipients for dividends paid prior to the forfeiture restrictions lapsing. Such dividend equivalents are not released from escrow if an award is forfeited.

Performance Stock Unit Awards

(1)The named executive officers are awarded a range of awards that may be earned based on attainment of goals between a target level of performance and a maximum level of performance.

(2)Performance stock unit awards granted prior to 2021, if earned, will be settled in shares of Pinnacle Financial Common Stock in the periods noted in the table, if Pinnacle Bank's ratio of non-performing assets to its loans plus ORE is less than amounts established in the applicable award agreement.

(3)Performance stock unit awards granted in 2021, if earned, will be settled in shares of Pinnacle Financial Common Stock in the period noted in the table, if the performance criterion included in the applicable performance unit award agreement are met.

During the six months ended June 30, 2021 and 2020, the restrictions associated with 133,041 and 129,723 performance stock unit awards granted in prior years lapsed, based on the terms of the agreement and approval by Pinnacle Financial's Human Resources and Compensation Committee, and were settled into shares of Pinnacle Financial common stock with 46,332 and 43,996 shares being withheld to pay the taxes associated with the settlement of those shares.

Additionally, during the six months ended June 30, 2021, 199,633 performance stock unit awards granted in prior years were forfeited due to the failure to reach performance targets for the year ended December 31, 2020 as defined in the associated performance stock unit award agreements.

Stock compensation expense related to restricted share awards, restricted stock unit awards and performance stock unit awards for the three and six months ended June 30, 2021 was $5.7 million and $11.1 million, respectively, compared to $4.1 million and $9.6 million, respectively, for the three and six months ended June 30, 2020. As of June 30, 2021, the total compensation cost related to unvested restricted share awards, restricted stock unit awards and performance stock unit awards not yet recognized was $59.9 million. This expense, if the underlying units are earned, is expected to be recognized over a weighted-average period of 1.72 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Note 8. Derivative Instruments

Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship and classification as either a cash flow hedge or fair value hedge for those derivatives which are designated as part of a hedging relationship.

Non-hedge derivatives

For derivatives not designated as hedges, the gain or loss is recognized in current period earnings. Pinnacle Financial enters into interest rate swaps (swaps) to facilitate customer transactions and meet their financing needs. Upon entering into these instruments to meet customer needs, Pinnacle Financial enters into offsetting positions in order to minimize the risk to Pinnacle Financial. These swaps qualify as derivatives, but are not designated as hedging instruments. The income statement impact of the offsetting positions is limited to changes in the reserve for counterparty credit risk. A summary of Pinnacle Financial's interest rate swaps to facilitate customers' transactions as of June 30, 2021 and December 31, 2020 is included in the following table (in thousands):

	June 30, 2021				December 31, 2020
	Notional Amount		Estimated Fair Value		Notional Amount		Estimated Fair Value
Interest rate swap agreements:
Assets	$	1,577,735	$	66,074	$	1,565,916	$	101,602
Liabilities	1,577,735		(66,890)		1,565,916		(102,919)
Total	$	3,155,470	$	(816)	$	3,131,832	$	(1,317)

The effects of Pinnacle Financial's interest rate swaps to facilitate customers' transactions on the income statement during the three and six months ended June 30, 2021 and 2020 were as follows (in thousands):

		Amount of Gain (Loss) Recognized in Income
	Location of Loss Recognized in Income	Three Months Ended June 30,				Six Months Ended June 30,

Interest rate swap agreements	Other noninterest income	$	51	$	(794)	$	501	$	(1,137)

Derivatives designated as cash flow hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income (loss), net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. Pinnacle Financial uses forward cash flow hedge relationships in an effort to manage future interest rate exposure. A summary of Pinnacle Financial's cash flow hedge relationships as of June 30, 2021 and December 31, 2020 is as follows (in thousands):

		June 30, 2021				December 31, 2020
	Balance Sheet Location	Notional Amount		Estimated Fair Value		Notional Amount		Estimated Fair Value

The effects of Pinnacle Financial's cash flow hedge relationships on the statement of comprehensive income (loss) during the three and six months ended June 30, 2021 and 2020 were as follows, net of tax (in thousands):

	Amount of Gain (Loss) Recognized in Other Comprehensive Income (Loss)
	Three Months Ended June 30,				Six Months Ended June 30,

	$	240	$	6,459	$	(15,034)	$	70,228

The cash flow hedges were determined to be highly effective during the periods presented and as a result qualify for hedge accounting treatment. If a hedge was deemed to be ineffective, the amount included in accumulated other comprehensive income (loss) would be reclassified into a line item within the statement of income that impacts operating results. The hedge would no longer be considered effective if a portion of the hedge becomes ineffective, the item hedged is no longer in existence or Pinnacle Financial discontinues hedge accounting. Gains on cash flow hedges totaling $2.7 million and $2.2 million, net of tax, were reclassified from accumulated other comprehensive income (loss) into net income during the three and six months ended June 30, 2021, respectively, compared to gains totaling $123,000 and losses totaling $1.7 million, net of tax, during the three and six months ended June 30, 2020, respectively. During the second quarter of 2021, loan interest rate floors with a notional amount totaling $1.5 billion and unrealized gains totaling $34.3 million, net of tax, were terminated. These unrealized gains are being amortized into income on a straight line basis through November 2024. Approximately $12.5 million in unrealized gains, net of tax, are expected to be reclassified from accumulated other comprehensive income (loss) into net income over the next twelve months related to previously terminated cash flow hedges.

Derivatives designated as fair value hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. Pinnacle Financial utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable available-for-sale securities. The hedging strategy converts the fixed interest rates to variable interest rates based on LIBOR or federal funds rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities.

A summary of Pinnacle Financial's fair value hedge relationships as of June 30, 2021 and December 31, 2020 is as follows (in thousands):

					June 30, 2021				December 31, 2020

Notional amounts of $477.5 million included in the table above receive a variable rate of interest based on three month LIBOR and notional amounts totaling $554.0 million receive a variable rate of interest based on the daily compounded federal funds rate.

The effects of Pinnacle Financial's securities fair value hedge relationships on the income statement during the three and six months ended June 30, 2021 and 2020 were as follows (in thousands):

	Location of Gain (Loss)	Amount of Gain (Loss) Recognized in Income

Securities available-for-sale	Interest income on securities	$	8,092	$	2,559	$	(26,674)	$	41,432

The following amounts were recorded on the balance sheet related to cumulative basis adjustments for fair value hedges at June 30, 2021 and December 31, 2020 (in thousands):

	Carrying Amount of the Hedged Assets				Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Note 9. Fair Value of Financial Instruments

FASB ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in U.S. GAAP and expands disclosures about fair value measurements.  The definition of fair value focuses on the exit price, i.e., the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, not the entry price, i.e., the price that would be paid to acquire the asset or received to assume the liability at the measurement date.  The statement emphasizes that fair value is a market-based measurement; not an entity-specific measurement.  Therefore, the fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability.

Valuation Hierarchy

FASB ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

•Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

•Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement.

A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.

Assets

Securities available-for-sale – Where quoted prices are available for identical securities in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government securities and certain other financial products. If quoted market prices are not available, then fair values are estimated by using pricing models that use observable inputs or quoted prices of securities with similar characteristics and are classified within Level 2 of the valuation hierarchy. In certain cases where there is limited activity or less transparency around inputs to the valuation and more complex pricing models or discounted cash flows are used, securities are classified within Level 3 of the valuation hierarchy.

Other investments – Included in other investments are investments recorded at fair value primarily in certain nonpublic investments and funds. The valuation of these nonpublic investments requires management judgment due to the absence of observable quoted market prices, inherent lack of liquidity and the long-term nature of such assets. These investments are valued initially based upon transaction price. The carrying values of other investments are adjusted either upwards or downwards from the transaction price to reflect expected exit values as evidenced by financing and sale transactions with third parties, or when determination of a valuation adjustment is confirmed through ongoing reviews by senior investment managers. A variety of factors are reviewed and monitored to assess positive and negative changes in valuation including, but not limited to, current operating performance and future expectations of the particular investment, industry valuations of comparable public companies and changes in market outlook and the third-party financing environment over time. In determining valuation adjustments resulting from the investment review process, emphasis is placed on current company performance and market conditions. These investments are included in Level 3 of the valuation hierarchy if the entities and funds are not widely traded and the underlying investments are in privately-held and/or start-up companies for which market values are not readily available. Certain investments in funds for which the underlying assets of the fund represent publicly traded investments are included in Level 2 of the valuation hierarchy.

Other assets – Included in other assets are certain assets carried at fair value, including interest rate swap agreements to facilitate customer transactions, interest rate floors designated as cash flow hedges, and interest rate locks associated with the mortgage loan pipeline. The carrying amount of interest rate swap agreements is based on Pinnacle Financial's pricing models that utilize observable market inputs. The fair value of the cash flow hedge agreements is determined by calculating the difference between the discounted fixed rate cash flows and the discounted variable rate cash flows. The fair value of the mortgage loan pipeline is based upon the projected sales price of the underlying loans, taking into account market interest rates and other market factors at the measurement date, net of the projected fallout rate.  Pinnacle Financial reflects these assets within Level 2 of the valuation hierarchy as these assets are valued using similar transactions that occur in the market.

Collateral dependent loans – Collateral dependent loans are measured at the fair value of the collateral securing the loan less estimated selling costs. The fair value of real estate collateral is determined based on real estate appraisals which are generally based on recent sales of comparable properties which are then adjusted for property specific factors. Non-real estate collateral is valued based on various sources, including third party asset valuations and internally determined values based on cost adjusted for depreciation and other judgmentally determined discount factors. Collateral dependent loans are classified within Level 3 of the hierarchy due to the unobservable inputs used in determining their fair value such as collateral values and the borrower's underlying financial condition.

Other real estate owned – Other real estate owned (OREO) represents real estate foreclosed upon by Pinnacle Bank through loan defaults by customers or acquired by deed in lieu of foreclosure. A significant portion of these amounts relate to lots, homes and development projects that are either completed or are in various stages of construction for which Pinnacle Financial believes it has adequate collateral. Upon foreclosure, the property is recorded at the lower of cost or fair value, based on appraised value, less selling costs estimated as of the date acquired with any loss recognized as a charge-off through the allowance for credit losses. Additional OREO losses for subsequent valuation downward adjustments are determined on a specific property basis and are included as a

component of noninterest expense along with holding costs. Any gains or losses realized at the time of disposal are also reflected in noninterest expense, as applicable. OREO is included in Level 3 of the valuation hierarchy due to the lack of observable market inputs into the determination of fair value as appraisal values are property-specific and sensitive to the changes in the overall economic environment.

Liabilities

Other liabilities – Pinnacle Financial has certain liabilities carried at fair value including certain interest rate swap agreements to facilitate customer transactions, interest rate swaps designated as fair value and cash flow hedges, and interest rate locks associated with the funding for its mortgage loan originations. The fair value of these liabilities is based on Pinnacle Financial's pricing models that utilize observable market inputs and is reflected within Level 2 of the valuation hierarchy.

In the case of the investment securities portfolio, Pinnacle Financial monitors the portfolio to ascertain when transfers between levels have been affected. The nature of the remaining assets and liabilities is such that transfers in and out of any level are expected to be rare. For the six months ended June 30, 2021, there were no transfers between Levels 1, 2 or 3.

The table below includes a rollforward of the balance sheet amounts for the three and six months ended June 30, 2021 and June 30, 2020 (including the change in fair value) for financial instruments classified by Pinnacle Financial within Level 3 of the valuation hierarchy measured at fair value on a recurring basis including changes in fair value due in part to observable factors that are part of the valuation methodology (in thousands):

The following tables present the carrying amounts, estimated fair value and placement in the fair value hierarchy of Pinnacle Financial's financial instruments at June 30, 2021 and December 31, 2020.  This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash, cash equivalents, and restricted cash, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as non-interest bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity (in thousands):

(1)Estimated fair values are consistent with an exit-price concept. The assumptions used to estimate the fair values are intended to approximate those that a market-participant would realize in a hypothetical orderly transaction.

(2)At the end of each quarter, Pinnacle Financial evaluates the inherent risks of the outstanding off-balance sheet commitments, including both commitments for unfunded loans and standby letters of credit. In making this evaluation, Pinnacle Financial utilizes credit loss expectations on funded loans from our allowance for credit losses methodology and evaluates the probability that the outstanding commitment will eventually become a funded loan. As a result, at June 30, 2021 and December 31, 2020, Pinnacle Financial included in other liabilities $23.2 million, representing expected credit losses on off-balance sheet commitments, which are reflected in the estimated fair values of the related commitments. Also included in the fair values at June 30, 2021 and December 31, 2020 are unamortized fees related to these commitments of $1.8 million and $1.7 million, respectively.

Regulatory Matters

Note 10. Regulatory Matters

Pursuant to Tennessee banking law, Pinnacle Bank may not, without the prior consent of the Commissioner of the Tennessee Department of Financial Institutions (TDFI), pay any dividends to Pinnacle Financial in a calendar year in excess of the total of Pinnacle Bank's retained net income for that year plus the retained net income for the preceding two years. Under Tennessee corporate law, Pinnacle Financial is not permitted to pay dividends if, after giving effect to such payment, it would not be able to pay its debts as they become due in the usual course of business or its total assets would be less than the sum of its total liabilities plus any amounts needed to satisfy any preferential rights if it were dissolving. In addition, in deciding whether or not to declare a dividend of any particular size, Pinnacle Financial's board of directors must consider its and Pinnacle Bank's current and prospective capital, liquidity, and other needs. In addition to state law limitations on Pinnacle Financial's ability to pay dividends, the Federal Reserve imposes limitations on Pinnacle Financial's ability to pay dividends. Federal Reserve regulations limit dividends, stock repurchases and discretionary bonuses to executive officers if Pinnacle Financial's regulatory capital is below the level of regulatory minimums plus the applicable capital conservation buffer.

In addition, the Federal Reserve has issued supervisory guidance advising bank holding companies to eliminate, defer or reduce dividends paid on common stock and other forms of Tier 1 capital where the company’s net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends, the company’s prospective rate of earnings retention is not consistent with the company’s capital needs and overall current and prospective financial condition or the company will not meet, or is in danger of not meeting, minimum regulatory capital adequacy ratios. Recent supplements to this guidance reiterate the need for bank holding companies to inform their applicable reserve bank sufficiently in advance of the proposed payment of a dividend in certain circumstances.

During the six months ended June 30, 2021, Pinnacle Bank paid $23.3 million dividends to Pinnacle Financial. As of June 30, 2021, Pinnacle Bank could pay approximately $681.9 million of additional dividends to Pinnacle Financial without prior approval of the Commissioner of the TDFI. Since the fourth quarter of 2013, Pinnacle Financial has paid a quarterly common stock dividend. The board of directors of Pinnacle Financial has increased the dividend amount per share over time. The most recent increase occurred on January 19, 2021, when the board of directors increased the dividend to $0.18 per common share from $0.16 per common share. During the second quarter of 2020, the Pinnacle Financial issued 9.0 million depositary shares, each representing a 1/40th fractional interest in a share of Series B noncumulative, perpetual preferred stock (the "Series B Preferred Stock") in a registered public offering to both retail and institutional investors. Beginning in the third quarter of 2020, Pinnacle Financial began paying a quarterly dividend of $16.88 per share (or $0.422 per depositary share), on the Series B Preferred Stock.

The amount and timing of all future dividend payments by Pinnacle Financial, if any, including dividends on Pinnacle Financial's Series B Preferred Stock, is subject to discretion of Pinnacle Financial's board of directors and will depend on Pinnacle Financial's receipt of dividends from Pinnacle Bank, earnings, capital position, financial condition and other factors, including regulatory capital requirements, as they become known to Pinnacle Financial and receipt of any regulatory approvals that may become required as a result of each of Pinnacle Financial's or Pinnacle Bank's financial results.

Pinnacle Financial and Pinnacle Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Pinnacle Financial and Pinnacle Bank must meet specific capital guidelines that involve quantitative measures of the assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Pinnacle Financial's and Pinnacle Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require Pinnacle Financial and its banking subsidiary to maintain minimum amounts and ratios of common equity Tier 1 capital to risk-weighted assets, Tier 1 capital to risk-weighted assets, total risk-based capital to risk-weighted assets and Tier 1 capital to average assets.

As permitted by the interim final rule issued on March 27, 2020 by the federal banking regulatory agencies, each of Pinnacle Bank and Pinnacle Financial has elected the option to delay the estimated impact on regulatory capital of Pinnacle Financial's and Pinnacle Bank's adoption of ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which was effective January 1, 2020. The initial impact of adoption of ASU 2016-13, as well as 25% of the quarterly changes in the allowance for credit losses subsequent to adoption of ASU 2016-13 (collectively the “transition adjustments”), will be delayed until December 31, 2021. After that date, the cumulative amount of the transition adjustments will become fixed and will be phased out of the regulatory capital calculations evenly over a three year period, with 75% recognized in

2022, 50% recognized in 2023, and 25% recognized in 2024. Beginning on January 1, 2025, the temporary regulatory capital benefits will be fully reversed.

Management believes, as of June 30, 2021, that Pinnacle Financial and Pinnacle Bank met all capital adequacy requirements to which they are subject. To be categorized as well-capitalized under applicable banking regulations, Pinnacle Bank must maintain certain total risk-based, Tier 1 risk-based, common equity Tier 1 and Tier 1 leverage ratios as set forth in the following table and not be subject to a written agreement, order or directive to maintain a higher capital level. The capital conservation buffer is not included in the required ratios of the table presented below. Pinnacle Financial's and Pinnacle Bank's actual capital amounts and resulting ratios, not including the capital conservation buffer, are presented in the following table (in thousands):

During the second quarter of 2020, Pinnacle Financial issued 9.0 million depositary shares, each representing a 1/40th interest in a share of Series B preferred stock in a registered public offering to both retail and institutional investors. Net proceeds from the transaction were approximately $217.1 million after deducting the underwriting discounts and offering expenses payable by Pinnacle Financial. The net proceeds were initially retained by Pinnacle Financial and the remaining net proceeds are available to support the capital needs of Pinnacle Financial and Pinnacle Bank, to support Pinnacle Financial's obligations, including interest payments on its outstanding indebtedness and dividend payments on the Series B preferred stock, and for other general corporate purposes.

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. generally accepted accounting principles (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 the consolidated financial statements and related notes appearing in Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2020 (2020 10-K).

These consolidated financial statements include the accounts of Pinnacle Financial and its wholly-owned subsidiaries. Certain statutory trust affiliates of Pinnacle Financial, as noted in Note 11. Other Borrowings are included in these consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminated in consolidation.

Use of Estimates

Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date 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 include the determination of the allowance for credit losses and determination of any impairment of goodwill or intangible assets. It is reasonably possible Pinnacle Financial's estimate of the allowance for credit losses and determination of impairment of goodwill or intangible assets could change as a result of the continued impact of the COVID-19 pandemic on the economy. The resulting change in these estimates could be material to Pinnacle Financial's consolidated financial statements. There have been no significant changes to Pinnacle Financial's significant accounting policies as disclosed in the 2020 10-K.

Income Per Common Share

Income Per Common Share — Basic net income per common share (EPS) is computed by dividing net income available to common shareholders by the weighted average common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The difference between basic and diluted weighted average common shares outstanding is attributable to common stock options, restricted share awards, and restricted share unit awards. The dilutive effect of outstanding options, restricted share awards, and restricted share unit awards is reflected in diluted EPS by application of the treasury stock method.

The following is a summary of the basic and diluted net income per common share calculations for the three and six months ended June 30, 2021 and 2020 (in thousands, except per share data):

	Three months ended June 30,				Six months ended June 30,

These amendments, among other things, clarify that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, Investments-Equity Method and Joint Ventures, for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments also clarify that when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. An entity should apply ASU 2020-01 prospectively at the beginning of the interim period that includes the adoption date. The amendments became effective for Pinnacle Financial on January 1, 2021 and had no impact on Pinnacle Financial's consolidated financial statements.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes to simplify various aspects of the current guidance to promote consistent application of the standard among reporting entities by moving certain exceptions to the general principles.

The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. Pinnacle Financial is implementing a transition plan to identify and modify its loans and other financial instruments, including certain indebtedness, with attributes that are either directly or indirectly influenced by LIBOR. Pinnacle Financial is assessing ASU 2020-04 and its impact on the transition away from LIBOR for its loans and other financial instruments.

(1) Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have doubts about the borrower's ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators for loans classified as substandard, excluding troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $169.3 million at June 30, 2021, compared to $173.5 million at December 31, 2020.

Pinnacle Financial has granted restricted share awards to associates and outside directors with a time-based vesting criteria. Compensation expense associated with time-based vesting restricted share awards is recognized over the time period that the restrictions associated with the awards lapse on a straight-line basis based on the total cost of the award. The following table outlines restricted stock grants that were made, grouped by similar vesting criteria, during the six months ended June 30, 2021. The table reflects the life-to-date activity for these awards:

Grant Year	Group (1)	Vesting Period in years			Shares awarded	Restrictions lapsed and shares released to participants	Shares withheld for taxes by participants	Shares Forfeited by participants (4)	Shares Unvested

Outside Director Awards (3)
2021	Outside directors			1	11,830	—	—	—	11,830

(1)Groups include employees (referred to as associates above) and outside directors. When the restricted shares are awarded, a participant receives voting rights and forfeitable dividend rights with respect to the shares, but is not able to transfer the shares until the restrictions have lapsed. Once the restrictions lapse, the participant is taxed on the value of the award and may elect to sell some shares (or have Pinnacle Financial withhold some shares) to pay the applicable income taxes associated with the award. Alternatively, the recipient can pay the withholding taxes in cash. For time-based vesting restricted share awards, dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination. For awards to Pinnacle Financial's directors, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.

(2)The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant.

(3)Restricted share awards are issued to the outside members of the board of directors in accordance with their board compensation plan. Restrictions lapse on March 1, 2022 based on each individual board member meeting attendance goals for the various board and board committee meetings to which each member was scheduled to attend.

(4)These shares represent forfeitures resulting from recipients whose employment or board membership was terminated during the year-to-date period ended June 30, 2021. Any dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination or will not be distributed from escrow, as applicable.

Schedule of Derivative Instruments

Derivatives designated as cash flow hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income (loss), net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. Pinnacle Financial uses forward cash flow hedge relationships in an effort to manage future interest rate exposure. A summary of Pinnacle Financial's cash flow hedge relationships as of June 30, 2021 and December 31, 2020 is as follows (in thousands):

		June 30, 2021				December 31, 2020

The effects of Pinnacle Financial's cash flow hedge relationships on the statement of comprehensive income (loss) during the three and six months ended June 30, 2021 and 2020 were as follows, net of tax (in thousands):

	Amount of Gain (Loss) Recognized in Other Comprehensive Income (Loss)
	Three Months Ended June 30,				Six Months Ended June 30,
Asset derivatives	2021		2020		2021		2020
Interest rate floor - loans	$	240	$	6,318	$	(15,034)	$	71,667

Interest rate swaps - borrowings	$	—	$	141	$	—	$	(1,439)
	$	240	$	6,459	$	(15,034)	$	70,228

The cash flow hedges were determined to be highly effective during the periods presented and as a result qualify for hedge accounting treatment. If a hedge was deemed to be ineffective, the amount included in accumulated other comprehensive income (loss) would be reclassified into a line item within the statement of income that impacts operating results. The hedge would no longer be considered effective if a portion of the hedge becomes ineffective, the item hedged is no longer in existence or Pinnacle Financial discontinues hedge accounting. Gains on cash flow hedges totaling $2.7 million and $2.2 million, net of tax, were reclassified from accumulated other comprehensive income (loss) into net income during the three and six months ended June 30, 2021, respectively, compared to gains totaling $123,000 and losses totaling $1.7 million, net of tax, during the three and six months ended June 30, 2020, respectively. During the second quarter of 2021, loan interest rate floors with a notional amount totaling $1.5 billion and unrealized gains totaling $34.3 million, net of tax, were terminated. These unrealized gains are being amortized into income on a straight line basis through November 2024. Approximately $12.5 million in unrealized gains, net of tax, are expected to be reclassified from accumulated other comprehensive income (loss) into net income over the next twelve months related to previously terminated cash flow hedges.

Derivatives designated as fair value hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. Pinnacle Financial utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable available-for-sale securities. The hedging strategy converts the fixed interest rates to variable interest rates based on LIBOR or federal funds rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities.

A summary of Pinnacle Financial's fair value hedge relationships as of June 30, 2021 and December 31, 2020 is as follows (in thousands):

Carrying Amounts, Estimated Fair Value and Placement in the Fair Value Hierarchy of Financial Instruments

The following tables present the carrying amounts, estimated fair value and placement in the fair value hierarchy of Pinnacle Financial's financial instruments at June 30, 2021 and December 31, 2020.  This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash, cash equivalents, and restricted cash, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as non-interest bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity (in thousands):

(1)Estimated fair values are consistent with an exit-price concept. The assumptions used to estimate the fair values are intended to approximate those that a market-participant would realize in a hypothetical orderly transaction.

(2)At the end of each quarter, Pinnacle Financial evaluates the inherent risks of the outstanding off-balance sheet commitments, including both commitments for unfunded loans and standby letters of credit. In making this evaluation, Pinnacle Financial utilizes credit loss expectations on funded loans from our allowance for credit losses methodology and evaluates the probability that the outstanding commitment will eventually become a funded loan. As a result, at June 30, 2021 and December 31, 2020, Pinnacle Financial included in other liabilities $23.2 million, representing expected credit losses on off-balance sheet commitments, which are reflected in the estimated fair values of the related commitments. Also included in the fair values at June 30, 2021 and December 31, 2020 are unamortized fees related to these commitments of $1.8 million and $1.7 million, respectively.

[1] Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have doubts about the borrower's ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators for loans classified as substandard, excluding troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $169.3 million at June 30, 2021, compared to $173.5 million at December 31, 2020.

[1] Groups include employees (referred to as associates above) and outside directors. When the restricted shares are awarded, a participant receives voting rights and forfeitable dividend rights with respect to the shares, but is not able to transfer the shares until the restrictions have lapsed. Once the restrictions lapse, the participant is taxed on the value of the award and may elect to sell some shares (or have Pinnacle Financial withhold some shares) to pay the applicable income taxes associated with the award. Alternatively, the recipient can pay the withholding taxes in cash. For time-based vesting restricted share awards, dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination. For awards to Pinnacle Financial's directors, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.

[2] The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant.

[3] These shares represent forfeitures resulting from recipients whose employment or board membership was terminated during the year-to-date period ended June 30, 2021. Any dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination or will not be distributed from escrow, as applicable.

[4] Restricted share awards are issued to the outside members of the board of directors in accordance with their board compensation plan. Restrictions lapse on March 1, 2022 based on each individual board member meeting attendance goals for the various board and board committee meetings to which each member was scheduled to attend.

Such dividend equivalents are not released from escrow if an award is forfeited.

[1] At the end of each quarter, Pinnacle Financial evaluates the inherent risks of the outstanding off-balance sheet commitments, including both commitments for unfunded loans and standby letters of credit. In making this evaluation, Pinnacle Financial utilizes credit loss expectations on funded loans from our allowance for credit losses methodology and evaluates the probability that the outstanding commitment will eventually become a funded loan. As a result, at June 30, 2021 and December 31, 2020, Pinnacle Financial included in other liabilities $23.2 million, representing expected credit losses on off-balance sheet commitments, which are reflected in the estimated fair values of the related commitments. Also included in the fair values at June 30, 2021 and December 31, 2020 are unamortized fees related to these commitments of $1.8 million and $1.7 million, respectively.

[2] Estimated fair values are consistent with an exit-price concept. The assumptions used to estimate the fair values are intended to approximate those that a market-participant would realize in a hypothetical orderly transaction.
