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) and BNC Bancorp (BNC) on July 31, 2015, September 1, 2015, July 1, 2016 and June 16, 2017, respectively. Pinnacle Bank completed its acquisition of Advocate Capital, Inc. (Advocate Capital) on July 2, 2019. Pinnacle Bank also holds 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 but also makes consumer loans for various purposes. The investment in BHG previously held by Pinnacle Financial was contributed to Pinnacle Bank effective September 30, 2022. Pinnacle Bank provides a full range of banking services, including investment, mortgage, insurance, and comprehensive wealth management services, in its 17 primarily urban markets and their surrounding communities. On March 1, 2022, Pinnacle Bank acquired the remaining 80% outstanding membership interest of JB&B Capital, LLC (JB&B) for a cash price of $32.0 million. JB&B is a commercial equipment financing business headquartered in Knoxville, TN. Pinnacle Bank had previously acquired 20% of JB&B in 2017. Pinnacle Financial accounted for the acquisition of JB&B under the acquisition method in accordance with ASC Topic 805, Business Combinations . Accordingly, the purchase price is allocated to the fair value of the assets acquired and liabilities assumed as of the date of the acquisition. Determining the fair value of assets and liabilities, particularly illiquid assets and liabilities, is a complicated process involving significant judgment regarding estimates and assumptions used to calculate estimated fair value. At the acquisition date, JB&B's net assets were recorded at a fair value of $12.9 million, consisting mainly of loans and leases receivable. JB&B's $29.5 million of indebtedness was also paid off in connection with consummation of the acquisition. The preexisting noncontrolling interest of JB&B held by Pinnacle Bank was remeasured at a fair value of $8.0 million on the acquisition date resulting in a gain on remeasurement of $5.5 million that was recorded in other noninterest income during the nine months ended September 30, 2022. The purchase price allocations for the acquisition of JB&B were finalized during the first quarter of 2023. 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, 2022 (2022 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 12. 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 intangible assets could change as a result of the uncertainty in current macroeconomic conditions. The resulting change in these estimates could be material to Pinnacle Financial's consolidated financial statements. Allowance for Credit Losses - Loans — Pinnacle Financial adopted FASB ASC 326, Financial Instruments - Credit Losses , effective January 1, 2020, which requires the estimation of an allowance for credit losses in accordance with the Current Expected Credit Losses (CECL) methodology. 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 a 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 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 through provision for credit losses and decreased by charge-offs, net of recoveries of amounts previously charged-off. During the second quarter of 2023, Pinnacle Financial implemented updated CECL models in an effort to ensure that risk in its portfolio at an individual loan level continues to be adequately captured given the uncertain state of the economy. The implementation of the new model had no material effect on the overall allowance for credit losses in the quarter of implementation. The allowance for credit losses is measured on a collective basis for pools of loans with similar risk characteristics. Pinnacle Financial has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses: • 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 granted under the Paycheck Protection Program (PPP), which are fully guaranteed by the Small Business Administration (SBA), are included in this category. • 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. For commercial real estate, consumer real estate, construction and land development, and commercial and industrial loans, Pinnacle Financial primarily utilizes a probability of default (PD) and loss given default (LGD) modeling approach. These models utilize historical correlations between default experience, loan level attributes and certain macroeconomic factors as determined through a statistical regression analysis. All loan segments modeled using this approach incorporate one or more macroeconomic drivers. Macroeconomic factors used in the model include the unadjusted and seasonally adjusted unemployment rate, gross domestic product, commercial property price index, consumer credit, commercial real estate price index, household debt ratio, household financial obligations ratio, and certain home price indices. Projections of these macroeconomic factors, obtained from an independent third party, are utilized to predict quarterly rates of default based on the statistical PD models. Adjustments are made to predicted default rates as considered necessary for each loan segment based on other quantitative and qualitative information not utilized as a direct input into the statistical models. The predicted quarterly default rates are then applied to the estimated future exposure at default (EAD), as determined based on contractual amortization terms and estimated prepayments. An estimated LGD, determined based on historical loss experience, is applied to the quarterly defaulted balances for each loan segment to estimate future losses of the loan's amortized cost. 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 September 30, 2023, a reasonable and supportable period of eighteen months was utilized for all loan segments, followed by a twelve month straight line reversion to long term averages. For the consumer and other loan segment, a loss rate approach is utilized. For these loans, historical charge off rates are applied to projected future balances, as determined in the same manner as EAD for the statistically modeled loan segments. For credit cards, which have no amortization terms or contractual maturities and are unconditionally cancellable, future balances are estimated based on expected payment volume applied to the current balance. The estimated loan losses for all loan segments are adjusted for changes in qualitative factors not inherently considered in the quantitative analyses. The qualitative categories and the measurements used to quantify the risks within each of these categories are subjectively selected by management but measured by objective measurements period over period. The data for each measurement may be obtained from internal or external sources. The current period measurements are evaluated and assigned a factor commensurate with the current level of risk relative to past measurements over time. The resulting qualitative adjustments are applied to the relevant collectively evaluated loan portfolios. These adjustments are based upon quarterly trend assessments in portfolio concentrations, policy exceptions, associate retention, independent loan review results, 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. Additional qualitative considerations are made for any identified risk which did not exist within our portfolio historically and therefore may not be adequately addressed through evaluation of such risk factor based on historical portfolio trends as previously discussed. 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. For loans individually evaluated for which repayment is expected to be provided substantially through the operation or sale of the collateral, Pinnacle Financial has elected the practical expedient under ASC 326 to estimate expected credit losses based on the fair value of the collateral, with selling costs considered in the event sale of the collateral is expected. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. Pinnacle Financial uses a probability of default/loss given default model to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. Occasionally, a loan modification will be granted by providing principal forgiveness on certain loans. When principal forgiveness is provided, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. In some cases, a loan restructuring will result in providing multiple types of modifications. Typically, one type of modification, such as a payment delay or term extension, is granted initially. If the borrower continues to experience financial difficulty, another modification, such as principal forgiveness or an interest rate reduction, may be granted. Additionally, multiple types of modifications may be made on the same loan within the current reporting period. Such a combination is at least two of the following: a payment delay, term extension, principal forgiveness, and interest rate reduction. Upon determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. In assessing the adequacy of the allowance for credit losses, Pinnacle Financial considers the results of Pinnacle Financial's ongoing independent loan review process. Pinnacle Financial undertakes this process both to ascertain those loans in the portfolio with elevated credit risk and to assist in its overall evaluation of the risk characteristics of the entire loan portfolio. Its loan review process includes the judgment of management, independent internal loan reviewers and reviews that may have been conducted by third-party reviewers including regulatory examiners. Pinnacle Financial incorporates relevant loan review results in the allowance. While policies and procedures used to estimate the allowance for credit losses, as well as the resultant provision for credit losses charged to income, are considered adequate by management and are reviewed periodically by regulators, model validators and internal auditors, they are necessarily approximate and imprecise. There are factors beyond Pinnacle Financial's control, such as changes in projected economic conditions, real estate markets or particular industry conditions which may materially impact asset quality and the adequacy of the allowance for credit losses and thus the resulting provision for credit losses. Other than the changes noted above under the section titled " Allowance for Credit Losses - Loans" , there have been no significant changes to Pinnacle Financial's significant accounting policies as disclosed in the 2022 10-K. Cash Flow Information — Supplemental cash flow information addressing certain cash and noncash transactions for the nine months ended September 30, 2023 and 2022 was as follows (in thousands): For the nine months ended 2023 2022 Cash Transactions: Interest paid $ 714,827 $ 114,326 Income taxes paid, net 96,698 115,090 Operating lease payments 22,648 13,528 Noncash Transactions: Loans charged-off to the allowance for credit losses 57,616 33,384 Loans foreclosed upon and transferred to other real estate owned 435 65 Loans foreclosed upon and transferred to other assets 561 — Available-for-sale securities transferred to held-to-maturity portfolio — 1,059,737 Right-of-use asset recognized during the period in exchange for lease obligations 195,995 31,333 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, including those with performance-based vesting provisions. 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 nine months ended September 30, 2023 and 2022 (in thousands, except per share data): Three months ended Nine months ended 2023 2022 2023 2022 Basic net income per common share calculation: Numerator - Net income available to common shareholders $ 128,805 $ 144,860 $ 455,779 $ 411,501 Denominator - Weighted average common shares outstanding 76,044 75,762 75,999 75,723 Basic net income per common share $ 1.69 $ 1.91 $ 6.00 $ 5.43 Diluted net income per common share calculation: Numerator - Net income available to common shareholders $ 128,805 $ 144,860 $ 455,779 $ 411,501 Denominator - Weighted average common shares outstanding 76,044 75,762 75,999 75,723 Dilutive common shares contingently issuable 158 217 104 222 Weighted average diluted common shares outstanding 76,202 75,979 76,103 75,945 Diluted net income per common share $ 1.69 $ 1.91 $ 5.99 $ 5.42 Recently Adopted Accounting Pronouncements — 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 was initially effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued an update to Accounting Standards Update 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting with Accounting Standards Update 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which updated the effective date to be March 12, 2020 through December 31, 2024. Pinnacle Financial implemented a transition plan to identify and convert its loans and other financial instruments, including certain indebtedness, with attributes that are either directly or indirectly influenced by LIBOR. Pinnacle Financial has moved the majority of its LIBOR-based loans to its preferred replacement index, a Secured Overnight Financing Rate (SOFR) based index as of September 30, 2023. For Pinnacle Financial's currently outstanding LIBOR-based loans, the timing and manner in which each customer's interest rate transitions to a replacement index will vary on a case-by-case basis and should occur at the next repricing date for these loans. In March 2022, the FASB issued Accounting Standards Update 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method , which allows multiple hedged layers to be designated for a single closed portfolio of financial assets resulting in a greater portion of the interest rate risk in the closed portfolio being eligible to be hedged. The amendments allow the flexibility to use different types of derivatives or combinations of derivatives to better align with risk management strategies. Furthermore, among other things, the amendments clarify that basis adjustments of hedged items in the closed portfolio should be allocated at the portfolio level and not the individual assets within the portfolio. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Pinnacle Financial adopted ASU 2022-01 on January 1, 2023 and it did not impact Pinnacle Financial's accounting or disclosures. In March 2022, the FASB issued Accounting Standards Update 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , which removes the accounting guidance for troubled debt restructurings and requires entities to evaluate whether a modification provided to a borrower results in a new loan or continuation of an existing loan. The amendments enhance existing disclosures and require new disclosures for receivables when there has been a modification in contractual cash flows due to a borrower experiencing financial difficulties. Additionally, the amendments require public business entities to disclose gross charge-off information by year of origination in the vintage disclosures. The guidance is effective for entities that have adopted ASU 2016-13 for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Pinnacle Financial adopted ASU 2022-02 on January 1, 2023 and incorporated the required disclosures into Note 4. Loans and Allowance for Credit Losses . Newly Issued Not Yet Effective Accounting Standards — In June 2022, the FASB issued Accounting Standards Update 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , which clarifies the guidance in ASC 820 when measuring the fair value of equity securities subject to contractual restrictions that prohibit the sale of an equity security. This update also requires specific disclosures related to these types of securities. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted, including early adoption in an interim period. An entity should apply ASU 2022-03 prospectively once adopted. Pinnacle Financial is assessing ASU 2022-03 and its potential impact on its accounting and disclosures. In March 2023, the FASB issued Accounting Standards Update 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method , which permits the use of the proportional amortization method of accounting for tax equity investments if certain conditions are met. A reporting entity makes the accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity or individual investment level. The amendments require specific disclosures that must be applied to all investments that generate tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted, including early adoption in an interim period. An entity should apply ASU 2023-02 on a retrospective or modified retrospective basis once adopted. Pinnacle Financial is assessing ASU 2023-02 and its potential impact on its accounting and disclosures. Other than those pronouncements discussed above and those which have been recently adopted, Pinnacle Financial does not believe there were any other recently issued accounting pronouncements that may materially impact its consolidated financial statements. Reclassifications — Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholder's equity. 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 September 30, 2023 through the date of the issued financial statements with no subsequent events being noted as of the date of this filing.

The related net unrealized after tax losses of $1.5 million, 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 transferred 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 September 30, 2023, approximately $1.9 billion 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 September 30, 2023, repurchase agreements comprised of secured borrowings totaled $196.0 million and were secured by $196.0 million of pledged U.S. government agency securities, mortgage-backed 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 the customers with whom it has entered into the repurchase agreements for the customers to remain adequately secured. The amortized cost and fair value of debt securities as of September 30, 2023 by contractual maturity is 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): Available-for-sale Held-to-maturity September 30, 2023: Amortized Fair Amortized Fair Due in one year or less $ 20,932 $ 22,591 $ 19,901 $ 19,059 Due in one year to five years 121,345 128,684 396,635 367,156 Due in five years to ten years 623,763 550,333 132,910 117,293 Due after ten years 2,270,077 2,110,720 1,886,096 1,562,186 Mortgage-backed securities 1,051,931 887,907 386,095 335,533 Asset-backed securities 178,213 163,462 198,650 180,005 $ 4,266,261 $ 3,863,697 $ 3,020,287 $ 2,581,232 At September 30, 2023 and December 31, 2022, the following available-for-sale securities had unrealized losses.

As such, it is possible that an available-for-sale security had a market value less than its amortized cost on other days during the twelve-month pe riods ended September 30, 2023 and December 31, 2022, but is not in the "Investments with an Unrealized Loss of less t han 12 months" category above. As shown in the tables above, at September 30, 2023, Pinnacle Financial had approximately $405.9 million in unrealized losses on approximately $3.6 billion of available-for-sale securities. 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 available-for-sale securities that have an unrealized loss at September 30, 2023, 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 of available-for-sale securities 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 available-for-sale securities at September 30, 2023 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 September 30, 2023. 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. Pinnacle Financial has a zero loss expectation for U.S. treasury securities in addition to U.S. Government agency securities and mortgage-backed securities issued by Ginnie Mae, Fannie Mae and Freddie Mac, and accordingly, no allowance for credit losses is estimated for these securities. Credit losses on held-to-maturity state and municipal securities and corporate notes and other securities are estimated using third-party probability of default and loss given default models driven primarily by macroeconomic factors over a reasonable and supportable period of eighteen months with a twelve month reversion to average loss factors. At September 30, 2023 and December 31, 2022, the estimated allowance for credit losses on these held-to-maturity securities was $1.7 million and $1.6 million, respectively, with the change driven largely by changes in macroeconomic forecasts. Pinnacle Financial utilizes bond credit ratings assigned by third party ratings agencies to monitor the credit quality of debt securities held-to-maturity. At September 30, 2023, 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 three and nine months ended September 30, 2023, $129.6 million and $303.1 million of available-for-sale securities were sold, respectively, resulting in gross realized gains of $289,000 and $302,000 and gross realized losses of $10.0 million and $20.0 million, respectively. During the three months ended September 30, 2022, $26.6 million of available-for-sale securities were sold resulting in gross realized gains of $292,000 and gross realized losses of $76,000, respectively. During the nine months ended September 30, 2022, $29.5 million of available-for-sale securities were sold resulting in gross realized gains of $292,000 and gross realized losses of $136,000. 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 9. 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	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. • 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 September 30, 2023 and December 31, 2022 were as follows (in thousands): September 30, 2023 December 31, 2022 Commercial real estate: Owner occupied $ 3,944,616 $ 3,587,257 Non-owner occupied 7,447,610 6,542,619 Consumer real estate – mortgage 4,768,780 4,435,046 Construction and land development 3,942,143 3,679,498 Commercial and industrial 11,307,611 10,241,362 Consumer and other 532,524 555,823 Subtotal $ 31,943,284 $ 29,041,605 Allowance for credit losses (346,192) (300,665) Loans, net $ 31,597,092 $ 28,740,940 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 that are less 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 September 30, 2023, approximately 79.2% 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 $1.5 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. 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 and the current period gross charge-offs by primary loan type and year of origination or most recent renewal as of September 30, 2023 (in thousands): September 30, 2023 2023 2022 2021 2020 2019 Prior Revolving Loans Total Commercial real estate - owner occupied Pass $ 564,968 $ 1,140,655 $ 869,651 $ 518,137 $ 299,408 $ 410,623 $ 47,514 $ 3,850,956 Special Mention 1,489 38,361 238 3,986 5,429 3,089 15,614 68,206 Substandard (1) 5,528 8,940 3,043 1,662 569 621 — 20,363 Substandard-nonaccrual 986 660 — 2,360 — 1,085 — 5,091 Doubtful-nonaccrual — — — — — — — — Total Commercial real estate - owner occupied $ 572,971 $ 1,188,616 $ 872,932 $ 526,145 $ 305,406 $ 415,418 $ 63,128 $ 3,944,616 Current period gross charge-offs $ — — — — — — — $ — Commercial real estate - non-owner occupied Pass $ 1,005,075 $ 2,663,004 $ 1,721,620 $ 779,796 $ 589,720 $ 458,572 $ 110,497 $ 7,328,284 Special Mention 3,174 30,455 — 6,788 218 7,348 — 47,983 Substandard (1) 24,641 2,974 40,156 — 1,216 562 — 69,549 Substandard-nonaccrual 1,641 153 — — — — — 1,794 Doubtful-nonaccrual — — — — — — — — Total Commercial real estate - non-owner occupied $ 1,034,531 $ 2,696,586 $ 1,761,776 $ 786,584 $ 591,154 $ 466,482 $ 110,497 $ 7,447,610 Current period gross charge-offs $ — — — — — — — $ — Consumer real estate – mortgage Pass $ 507,284 $ 990,832 $ 1,062,479 $ 455,584 $ 212,988 $ 329,196 $ 1,190,763 $ 4,749,126 Special Mention — — — — — — — — Substandard (1) — — — — — — — — Substandard-nonaccrual 256 1,372 2,743 4,412 6,427 3,848 596 19,654 Doubtful-nonaccrual — — — — — — — — Total Consumer real estate – mortgage $ 507,540 $ 992,204 $ 1,065,222 $ 459,996 $ 219,415 $ 333,044 $ 1,191,359 $ 4,768,780 Current period gross charge-offs $ — (85) (80) (6) (49) (378) — $ (598) Construction and land development Pass $ 888,677 $ 1,843,853 $ 1,054,829 $ 69,024 $ 12,317 $ 7,138 $ 41,491 $ 3,917,329 Special Mention 3,419 16,107 887 4,318 — — — 24,731 Substandard (1) — — — — — 83 — 83 Substandard-nonaccrual — — — — — — — — Doubtful-nonaccrual — — — — — — — — Total Construction and land development $ 892,096 $ 1,859,960 $ 1,055,716 $ 73,342 $ 12,317 $ 7,221 $ 41,491 $ 3,942,143 Current period gross charge-offs $ — — — — — (3) — $ (3) Commercial and industrial Pass $ 3,094,118 $ 2,341,941 $ 1,229,428 $ 349,426 $ 240,221 $ 167,914 $ 3,675,820 $ 11,098,868 Special Mention 11,668 10,675 33,138 1,698 165 2,355 54,795 114,494 Substandard (1) 11,538 1,208 1,154 1,974 1,494 9,068 51,484 77,920 Substandard-nonaccrual 8,624 4,524 1,786 96 377 388 534 16,329 Doubtful-nonaccrual — — — — — — — — Total Commercial and industrial $ 3,125,948 $ 2,358,348 $ 1,265,506 $ 353,194 $ 242,257 $ 179,725 $ 3,782,633 $ 11,307,611 Current period gross charge-offs $ (2,170) (20,287) (9,840) (686) (88) (301) (11,786) $ (45,158) Consumer and other Pass $ 136,325 $ 32,958 $ 72,241 $ 40,743 $ 712 $ 752 $ 248,711 $ 532,442 Special Mention — — — — — — — — Substandard (1) — — — — — — — — September 30, 2023 2023 2022 2021 2020 2019 Prior Revolving Loans Total Substandard-nonaccrual — 5 — — — — 77 82 Doubtful-nonaccrual — — — — — — — — Total Consumer and other $ 136,325 $ 32,963 $ 72,241 $ 40,743 $ 712 $ 752 $ 248,788 $ 532,524 Current period gross charge-offs $ (29) (436) (5,236) (2,183) (140) (64) (3,769) $ (11,857) Total loans Pass $ 6,196,447 $ 9,013,243 $ 6,010,248 $ 2,212,710 $ 1,355,366 $ 1,374,195 $ 5,314,796 $ 31,477,005 Special Mention 19,750 95,598 34,263 16,790 5,812 12,792 70,409 255,414 Substandard (1) 41,707 13,122 44,353 3,636 3,279 10,334 51,484 167,915 Substandard-nonaccrual 11,507 6,714 4,529 6,868 6,804 5,321 1,207 42,950 Doubtful-nonaccrual — — — — — — — — Total loans $ 6,269,411 $ 9,128,677 $ 6,093,393 $ 2,240,004 $ 1,371,261 $ 1,402,642 $ 5,437,896 $ 31,943,284 Current period gross charge-offs $ (2,199) (20,808) (15,156) (2,875) (277) (746) (15,555) $ (57,616) (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 loan modifications made to borrowers experiencing financial difficulty. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $134.5 million at September 30, 2023, compared to $53.8 million at December 31, 2022.

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. During the second quarter of 2023, Pinnacle Financial implemented updated CECL models in an effort to ensure that risk in its portfolio continues to be adequately captured given the uncertain state of the economy. CECL methodology requires the allowance for credit losses to be 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. 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 and loss experience, loan level attributes, and certain macroeconomic factors as determined through a statistical regression analysis. Segments using this approach incorporate various economic drivers. Under the current model, commercial and industrial loans consider gross domestic product (GDP), the consumer credit index and the national unemployment rate, commercial construction loans and commercial real estate loans including nonowner occupied and owner occupied commercial real estate loans consider the national unemployment rate and the commercial property and commercial real estate price indices, construction and land development loans consider the commercial property, consumer credit and home price indices dependent upon their use as residential versus commercial, consumer real estate loans consider the home price index and household debt ratio and other consumer loans consider the national unemployment rate and the household financial obligations ratio. Under the previous model, all loan segments considered changes in the national unemployment rate. In addition to the national unemployment rate, GDP and the three-month treasury rate were considered for owner occupied commercial real estate loans, the commercial real estate price index and the five-year treasury rate were considered for construction loans, and the three-month treasury rate was considered for commercial and industrial loans. A third-party provides management with quarterly macroeconomic scenarios, which management evaluates to determine the best estimate of the expected losses. For the consumer and other loan segment, a non-statistical approach based on historical charge off rates is utilized. The implementation of the new model including the addition of, and changes to, macroeconomic factors considered had no material effect on the overall allowance for credit losses. 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. A reasonable and supportable period of eighteen months was utilized for all loan segments at September 30, 2023 as compared to twenty-four months at December 31, 2022, followed by a twelve month straight line reversion to long term averages at each measurement date. 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, 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 September 30, 2023 and December 31, 2022 (in thousands): Real Estate Business Assets Other Total September 30, 2023 Commercial real estate: Owner occupied $ 24,243 $ — $ — $ 24,243 Non-owner occupied 28,933 — — 28,933 Consumer real estate – mortgage 22,435 — — 22,435 Construction and land development 61 — — 61 Commercial and industrial — 24,618 630 25,248 Consumer and other — — — — Total $ 75,672 $ 24,618 $ 630 $ 100,920 December 31, 2022 Commercial real estate: Owner occupied $ 10,804 $ — $ — $ 10,804 Non-owner occupied 4,795 — — 4,795 Consumer real estate – mortgage 22,466 — — 22,466 Construction and land development 299 — — 299 Commercial and industrial — 12,327 — 12,327 Consumer and other — — 2 2 Total $ 38,364 $ 12,327 $ 2 $ 50,693 The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. Pinnacle Financial uses a probability of default/loss given default model to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. Occasionally, a loan modification will be granted by providing principal forgiveness on certain loans. When principal forgiveness is provided, the amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. In some cases, a loan restructuring will result in providing multiple types of modifications. Typically, one type of modification, such as a payment delay or term extension, is granted initially. If the borrower continues to experience financial difficulty, another modification, such as principal forgiveness or an interest rate reduction, may be granted. Additionally, multiple types of modifications may be made on the same loan within the current reporting period. Such a combination is at least two of the following: a payment delay, term extension, principal forgiveness, and interest rate reduction. Upon determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. The following table shows the amortized cost basis of the loans modified to borrowers experiencing financial difficulty during the three and nine months ended September 30, 2023 (all of which modifications occurred in the three months ended September 30, 2023), disaggregated by class of loans and type of modification granted and describes the financial effect of the modifications made to borrowers experiencing financial difficulty (in thousands): Three and nine months ended September 30, 2023 Payment Delay Term Extension Combination¹ Total % Total % Total % Total Commercial real estate: Owner occupied $ — — % $ 5,528 0.14 % $ — — % $ 5,528 Non-owner occupied 11,165 0.15 % — — % 13,476 0.18 % 24,641 Consumer real estate – mortgage — — % — — % — — % — Construction and land development — — % — — % — — % — Commercial and industrial — — % 3,225 0.03 % — — % 3,225 Consumer and other — — % — — % — — % — Total $ 11,165 $ 8,753 $ 13,476 $ 33,394 ¹ The combination includes payment delay, term extension, and an interest rate reduction.

Pinnacle Financial charged off $357,000 of previously modified commercial and industrial loans during the three months ended September 30, 2023. The table below presents the amortized cost basis of loans on nonaccrual status and loans past due 90 or more days and still accruing interest at September 30, 2023 and December 31, 2022. Also presented is the balance of loans on nonaccrual status at September 30, 2023 for which there was no related allowance for credit losses recorded (in thousands): September 30, 2023 December 31, 2022 Total nonaccrual loans Nonaccrual loans with no allowance for credit losses Loans past due 90 or more days and still accruing Total nonaccrual loans Nonaccrual loans with no allowance for credit losses Loans past due 90 or more days and still accruing Commercial real estate: Owner occupied $ 5,091 $ 2,339 $ — $ 1,882 $ — $ — Non-owner occupied 1,794 1,641 — 2,244 1,040 — Consumer real estate – mortgage 19,654 1,299 — 17,330 — — Construction and land development — — — 231 — — Commercial and industrial 16,329 — 3,608 16,345 8,003 3,663 Consumer and other 82 — 1,361 84 — 743 Total $ 42,950 $ 5,279 $ 4,969 $ 38,116 $ 9,043 $ 4,406 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 nine months ended September 30, 2023 and 2022, respectively. Had these loans been on accruing status, an additional $1.2 million and $3.1 million of interest income would have been recognized for the three and nine months ended September 30, 2023, respectively, compared to an additional $240,000 and $864,000 for the three and nine months ended September 30, 2022, respectively. Approximately $9.2 million and $6.4 million of nonaccrual loans were performing pursuant to their contractual terms as of September 30, 2023 and December 31, 2022, respectively. 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 September 30, 2023 with the comparative exposures for December 31, 2022 (in thousands): September 30, 2023 Outstanding Principal Balances Unfunded Commitments Total exposure Total Exposure at December 31, 2022 Lessors of nonresidential buildings $ 4,672,499 $ 1,545,847 $ 6,218,346 $ 7,058,045 Lessors of residential buildings 1,793,549 1,296,827 3,090,376 3,725,186 New Housing For-Sale Builders 547,566 918,711 1,466,277 1,763,089 Music Publishers 744,947 477,077 1,222,024 1,127,636 Among other data, 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 September 30, 2023 and December 31, 2022, Pinnacle Bank’s construction and land development loans as a percentage of total risk-based capital were 83.1% and 85.9%, 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 256.4% and 249.6% as of September 30, 2023 and December 31, 2022, 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 September 30, 2023, Pinnacle Bank was within the 100% and 300% guidelines and has established what it believes to be appropriate monitoring of its lending in these areas as it aims to keep the level of these loans below the 100% and 300% thresholds. At September 30, 2023, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $38.3 million to current directors, executive officers, and their related interests, of which $34.4 million had been drawn upon. At December 31, 2022, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $20.9 million to directors, executive officers, and their related interests, of which approximately $16.0 million had been drawn upon. All loans to directors, executive officers, and their related interests were performing in accordance with contractual terms at September 30, 2023 and December 31, 2022. Loans Held for Sale At September 30, 2023, Pinnacle Financial had approximately $20.5 million in commercial loans held for sale compared to $21.1 million at December 31, 2022. These include 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. Also included are commercial loans originated for sale to BHG as part of BHG's alternative financing portfolio. At September 30, 2023, Pinnacle Financial had approximately $25.1 million of mortgage loans held-for-sale compared to approximately $12.9 million at December 31, 2022. Total mortgage loan volumes sold during the nine months ended September 30, 2023 were approximately $511.3 million compared to approximately $691.7 million for the nine months ended September 30, 2022. During the three and nine months ended September 30, 2023, Pinnacle Financial recognized $2.0 million and $5.6 million, respectively, in gains on the sale of these loans, net of commissions paid, compared to $1.1 million and $7.3 million, respectively, during the three and nine months ended September 30, 2022. These residential 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 residential 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

Pinnacle Financial has entered into various operating leases, primarily for office space and branch facilities. The leases are classified as operating or finance leases at commencement. Right-of-use assets representing the right to use the underlying asset and lease liabilities representing the obligation to make future lease payments are recognized on the balance sheet within other assets other liabilities renewal options which are considered in the determination of the lease term if they are deemed reasonably certain to be exercised. Pinnacle Financial has elected not to recognize leases with an original term of less than 12 months on the balance sheet. During the second quarter of 2023, Pinnacle Bank consummated a sale-leaseback transaction pursuant to which it sold a combined 49 properties to two unaffiliated entities, PNB TN Portfolio Owner LLC and PNB Portfolio Owner, LLC (each, a "Purchaser" and collectively, the "Purchasers"), each of whom is an affiliate of Oak Street Real Estate Capital, for an aggregate cash purchase price of $198.2 million and concurrently agreed to separately lease each of those properties for an initial term of 14.5 years, with two five (5) year renewal options that Pinnacle Bank may exercise to extend the term of any of the leases. The pre-tax, net gain recorded associated with the sale of these 49 properties was $85.7 million, after deducting transaction-related expenses. The aggregate annual lease expense associated with these properties will be approximately $17.0 million for the first twelve months of the lease term, with each lease including a 1.9% annual rent escalation during the initial term, and a 2.0% annual rent escalation during each of the two five-year renewal terms, if exercised. The proceeds of the sale-leaseback transaction have been retained in Pinnacle Bank's cash accounts at the Federal Reserve, where they are currently anticipated to remain through at least the end of 2023. Right-of-use assets and lease liabilities relating to Pinnacle Financial's operating and finance leases are as follows at September 30, 2023 and December 31, 2022 (in thousands): September 30, 2023 December 31, 2022 Right-of-use assets: Operating leases $ 293,013 $ 126,767 Finance leases 1,148 1,318 Total right-of-use assets $ 294,161 $ 128,085 Lease liabilities: Operating leases $ 300,965 $ 133,108 Finance leases 2,233 2,458 Total lease liabilities $ 303,198 $ 135,566 The total lease cost related to operating leases and short term leases is recognized on a straight-line basis over the lease term. For finance leases, right-of-use assets are amortized on a straight-line basis over the lease term and interest imputed on the lease liability is recognized using the effective interest method.

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 $9.4 million and $15.8 million at September 30, 2023 and December 31, 2022, respectively. During the three months ended September 30, 2023, Pinnacle Financial paid no taxes related to state income tax filings for tax years prior to 2023. During the nine months ended September 30, 2023, Pinnacle Financial paid $6.3 million in taxes related to state income tax filings for tax years prior to 2023. No change was recorded to the unrecognized tax benefit related to uncertain tax positions for the three and nine month periods ended September 30, 2022. Pinnacle Financial's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. No interest and penalties were recognized during the three and nine months ended September 30, 2023. No interest and penalties were recognized for the three months ended September 30, 2022. Pinnacle Financial recognized $264,000 in interest and penalties for the nine months ended September 30, 2022. Pinnacle Financial's effective tax rate for the three and nine months ended September 30, 2023 was 21.1% and 20.2%, respectively, compared to 19.1% for both the three and nine months ended September 30, 2022. The difference between the effective tax rate and the federal and state income tax statutory rate of 25.00% and 26.14% at September 30, 2023 and 2022, respectively, 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 as 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. For the three and nine months ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Note 7. 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 September 30, 2023, these commitments amounted to $15.6 billion, of which approximately $1.8 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 September 30, 2023, these commitments amounted to $326.8 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 September 30, 2023 and December 31, 2022, Pinnacle Financial had accrued reserves of $21.5 million and $25.0 million, respectively, for the inherent risks associated with these off-balance sheet commitments. There was no provision for these unfunded commitments for the three months ended September 30, 2023 and a decrease of $3.5 million for the nine months ended September 30, 2023. For the same periods in 2022, there were increases of $500,000 and $2.0 million, respectively, to the provision for unfunded 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 September 30, 2023 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 8. Stock Options and Restricted Shares Pinnacle Financial's Amended and Restated 2018 Omnibus Equity Incentive Plan (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 September 30, 2023, there were approximately 928,000 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 September 30, 2023, 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 nine months ended September 30, 2023 and information regarding, contractual terms remaining, intrinsic values and other matters is as follows: Number Weighted-Average Weighted-Average Aggregate Outstanding at December 31, 2022 40,188 $ 25.00 0.33 $ 1,945 (1) Granted — Exercised (40,188) Forfeited — Outstanding at September 30, 2023 — $ — — $ — Options exercisable at September 30, 2023 — $ — — $ — (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 $73.40 per common share at December 31, 2022 for the 40,188 options that were in-the-money at December 31, 2022. Compensation costs related to stock options granted under Pinnacle Financial's equity incentive plans have been fully recognized and, as of September 30, 2023, there were no further options outstanding under any of Pinnacle Financial's equity incentive plans. Restricted Share Awards A summary of activity for unvested restricted share awards for the nine months ended September 30, 2023 is as follows: Number Grant Date Unvested at December 31, 2022 675,611 $ 78.53 Shares awarded 239,898 Restrictions lapsed and shares released to associates/directors (183,915) Shares forfeited (21,316) Unvested at September 30, 2023 710,278 $ 77.84 Pinnacle Financial has granted restricted share awards to associates and outside directors with 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 nine months ended September 30, 2023. The table reflects the life-to-date activity for these awards: Grant Group (1) Vesting Shares Restrictions lapsed and shares released to participants Shares withheld for taxes by participants Shares forfeited by participants (4) Shares unvested Time Based Awards 2023 Associates (2) 5 229,058 270 152 6,358 222,278 Outside Director Awards (3) 2023 Outside directors 1 10,840 — — — 10,840 (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, 2024 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 September 30, 2023. 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 A summary of activity for unvested restricted stock units for the nine months ended September 30, 2023 is as follows: Number Grant Date Unvested at December 31, 2022 73,983 $ 88.21 Shares awarded 70,716 Restrictions lapsed and shares released to associates (31,392) Shares forfeited (7,167) Unvested at September 30, 2023 106,140 $ 77.91 Pinnacle Financial grants 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 nine months ended September 30, 2023. The table reflects the life-to-date activity for these awards: Grant year Vesting Shares Restrictions lapsed and shares released to participants Shares withheld for taxes by participants Shares forfeited by participants (1) Shares unvested 2023 3 70,716 153 100 4,233 66,230 (1) These shares represent forfeitures resulting from recipients whose employment was terminated during the year-to-date period ended September 30, 2023. 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 The following table details the performance stock unit awards outstanding at September 30, 2023: Units Awarded Grant year NEOs (1) Leadership Team other than NEOs Applicable performance periods associated with each tranche Service period per tranche Subsequent holding period per tranche Period in which units to be settled into shares of common stock (2) 2023 103,136 — 247,515 61,673 2023-2025 0 0 2026 2022 56,465 — 135,514 32,320 2022-2024 0 0 2025 2022 — — 230,000 — 2022-2024 0 1 2026 2021 89,234 — 214,155 45,240 2021-2023 0 0 2024 2020 136,137 — 204,220 59,648 2020 2 3 2025 2021 2 2 2025 2022 2 1 2025 2019 166,211 — 249,343 52,244 2019 2 3 2024 2020 2 2 2024 2021 2 1 2024 (1) The named executive officers are awarded a range of awards that generally may be earned based on attainment of goals between a target level of performance and a maximum level of performance. The 230,000 performance units awarded to the NEOs in 2022 may be earned based on target level performance and do not include a maximum level payout. (2) Performance stock unit awards granted in or after 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 nine months ended September 30, 2023 and 2022, the restrictions associated with 111,108 and 149,893 performance stock unit awards previously granted, respectively, lapsed based on the terms of the underlying award agreements and approval by Pinnacle Financial's Human Resources and Compensation Committee. Also, during the nine months ended September 30, 2023 and 2022, such awards were settled into shares of Pinnacle Financial common stock with 38,782 and 53,125, respectively, shares being withheld to pay the taxes associated with the settlement of those shares. Stock compensation expense related to restricted share awards, restricted stock unit awards and performance stock unit awards for the three and nine months ended September 30, 2023 was $10.1 million and $29.6 million, respectively, compared to $10.7 million and $30.9 million, respectively, for the three and nine months ended September 30, 2022. As of September 30, 2023, the total compensation cost related to unvested restricted share awards, restricted stock unit awards and performance stock unit awards estimated at maximum performance not yet recognized was $72.7 million. This expense, if the underlying units are earned, is expected to be recognized over a weighted-average period of 1.93 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 9. 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. Pinnacle Financial's derivative instruments with certain counterparties contain legally enforceable netting that allow multiple transactions to be settled into a single amount. The fair value hedge and interest rate swaps (swaps) assets and liabilities are presented at gross fair value before the application of bilateral collateral and master netting agreements, but after the initial margin posting and daily variation margin payments made with central clearinghouse organizations. Total fair value hedge and swaps assets and liabilities are adjusted to take into consideration the effects of legally enforceable master netting agreements and cash collateral received or paid as of September 30, 2023 and December 31, 2022. The resulting net fair value hedge and swaps asset and liability fair values are included in other assets and other liabilities, respectively, on the consolidated balance sheets. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument. 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 September 30, 2023 and December 31, 2022 is included in the following table (in thousands): September 30, 2023 December 31, 2022 Notional Estimated Fair Value (1) Notional Estimated Fair Value (1) Interest rate swap agreements: Assets $ 1,886,702 $ 117,072 $ 1,620,520 $ 39,763 Liabilities 1,886,702 (118,367) 1,620,520 (96,483) Total $ 3,773,404 $ (1,295) $ 3,241,040 $ (56,720) (1) The variation margin payments for derivatives cleared through central clearing houses are characterized as settlements. At September 30, 2023, there were no interest rate swap agreements designated as non-hedge derivatives cleared through clearing houses. At December 31, 2022, the notional amount of interest rate swap agreements designated as non-hedge derivatives cleared through clearing houses was $827.3 million with a fair value that approximates zero due to $56.3 million in received variation margin payments. The effects of Pinnacle Financial's interest rate swaps to facilitate customers' transactions on the income statement during the three and nine months ended September 30, 2023 and 2022 were as follows (in thousands): Amount of Gain (Loss) Recognized in Income Location of Gain (Loss) Recognized in Income Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 Interest rate swap agreements Other noninterest income $ (265) $ (207) $ (847) $ 34 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 the cash flow hedge relationships as of September 30, 2023 and December 31, 2022 is as follows (in thousands): September 30, 2023 December 31, 2022 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Receive Rate Pay Rate Notional Amount Estimated Fair Value Notional Amount Estimated Fair Value Asset derivatives Interest rate floor - loans Other assets 4.09 4.00%-4.50% minus USD-Term SOFR 1M N/A $ 875,000 $ 25,225 $ 875,000 $ 48,622 Interest rate collars - loans Other assets 4.09 4.25%-4.75% minus USD-Term SOFR 1M USD-Term SOFR 1M minus 6.75%-7.00% 875,000 23,745 875,000 45,553 $ 1,750,000 $ 48,970 $ 1,750,000 $ 94,175 The effects of Pinnacle Financial's cash flow hedge relationships on the statement of comprehensive income (loss) during the three and nine months ended September 30, 2023 and 2022 were as follows, net of tax (in thousands): Amount of Loss Recognized Three Months Ended September 30, Nine Months Ended September 30, Asset derivatives 2023 2022 2023 2022 Interest rate floors and collars - loans $ (17,403) $ — $ (28,764) $ — 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 $2.5 million and $7.2 million, net of tax, were reclassified from accumulated other comprehensive income (loss) into net income during the three and nine months ended September 30, 2023, respectively, compared to $2.5 million and $7.5 million, net of tax, during the three and nine months ended September 30, 2022, respectively. Approximately $9.8 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 federal funds rates or SOFR. 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. In March 2023, Pinnacle Financial entered into fair value hedges with aggregate notional amounts of $425.0 million to mitigate the effect of changing interest rates on FHLB Cincinnati (FHLB) advances with payments beginning in the first quarter of 2024. In May 2023, Pinnacle Financial entered into additional fair value hedges with aggregate notional amounts of $425.0 million to mitigate the effect of changing interest rates on FHLB advances with payments beginning in the fourth quarter of 2024 and first quarter of 2025. A summary of Pinnacle Financial's fair value hedge relationships as of September 30, 2023 and December 31, 2022 is as follows (in thousands): September 30, 2023 December 31, 2022 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Weighted Average Pay Rate Receive Rate Notional Amount Estimated Fair Value (1) Notional Amount Estimated Fair Value (1) Asset derivatives Interest rate swaps - securities Other assets 10.78 2.75% Federal Funds/ SOFR $ 2,012,139 $ 73,550 $ 1,420,724 $ 56,056 Liability derivatives Interest rate swaps - borrowings Other liabilities 4.32 N/A —% $ 850,000 $ (12,338) $ — $ — $ 2,862,139 $ 61,212 $ 1,420,724 $ 56,056 (1) The variation margin payments for derivatives cleared through central clearing houses are characterized as settlements. At September 30, 2023 and December 31, 2022, the notional amount of fair value derivatives cleared through central clearing houses was $1.9 billion and $877.7 million with a fair value that approximates zero due to $80.6 million and $47.9 million in received variation margin. Notional amounts of $392.2 million as of September 30, 2023 receive a variable rate of interest based on the daily compounded federal funds rate and notional amounts totaling $1.6 billion as of September 30, 2023 receive a variable rate of interest based on the daily compounded SOFR. Notional amounts receiving a variable rate of interest based on three month LIBOR transitioned to three month SOFR plus a comparable tenor spread adjustment on future rate adjustment dates occurring after June 30, 2023. The effects of Pinnacle Financial's securities fair value hedge relationships on the income statement during the three and nine months ended September 30, 2023 and 2022 were as follows (in thousands): Location of Gain (Loss) Amount of Gain (Loss) Recognized in Income Three Months Ended September 30, Nine Months Ended September 30, Securities 2023 2022 2023 2022 Interest rate swaps - securities Interest income on securities $ 15,669 $ 67,917 $ 17,494 $ 132,100 Securities available-for-sale Interest income on securities $ (15,669) $ (67,917) $ (17,494) $ (132,100) FHLB advances Interest rate swaps - FHLB advances Interest expense on FHLB advances and other borrowings $ 1,559 $ — $ (12,338) $ — FHLB advances Interest expense on FHLB advances and other borrowings $ (1,559) $ — $ 12,338 $ — The following amounts were recorded on the balance sheet related to cumulative basis adjustments for fair value hedges at September 30, 2023 and December 31, 2022 (in thousands): Carrying Amount of the Hedged Assets/Liabilities Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets/Liabilities September 30, 2023 December 31, 2022 September 30, 2023 December 31, 2022 Line item on the balance sheet Securities available-for-sale $ 1,957,510 $ 1,445,511 $ (73,550) $ (56,056) Federal Home Loan Bank advances $ 837,662 $ — $ (12,338) $ — During the three and nine months ended September 30, 2023 and 2022 amortization expense totaling $141,000 and $519,000, respectively, compared to $408,000 and $1.6 million, respectively, for the three and nine months ended September 30, 2022, related to previously terminated fair value hedges was recognized as a reduction to interest income on loans.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 10. Fair Value of Financial Instruments FASB ASC 820, Fair Value Measurements , 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 financial reports provided by the portfolio managers of the investments. 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 swaps designated as fair value hedges, interest rate caps and 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 completion 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 hedges, interest rate caps and floors designated as 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 September 30, 2023 and December 31, 2022, by caption on the consolidated balance sheets and by FASB ASC 820 valuation hierarchy (as described above) (in thousands): Total carrying value in the consolidated balance sheet Quoted market prices in an active market Models with significant observable market parameters Models with significant unobservable market parameters September 30, 2023 Investment securities available-for-sale: U.S. Treasury securities $ 729,156 $ — $ 729,156 $ — U.S. Government agency securities 255,105 — 255,105 — Mortgage-backed securities 887,907 — 887,907 — State and municipal securities 1,411,123 — 1,410,652 471 Agency-backed securities 163,462 — 163,462 — Corporate notes and other 416,944 — 416,944 — Total investment securities available-for-sale 3,863,697 — 3,863,226 471 Other investments 178,040 — 21,377 156,663 Other assets 264,118 — 264,118 — Total assets at fair value $ 4,305,855 $ — $ 4,148,721 $ 157,134 Other liabilities $ 154,119 $ — $ 154,119 $ — Total carrying value in the consolidated balance sheet Quoted market prices in an active market Models with significant observable market parameters Models with significant unobservable market parameters Total liabilities at fair value $ 154,119 $ — $ 154,119 $ — December 31, 2022 Investment securities available-for-sale: U.S. Treasury securities $ 194,184 $ — $ 194,184 $ — U.S. Government agency securities 396,157 — 396,157 — Mortgage-backed securities 971,576 — 971,576 — State and municipal securities 1,412,306 — 1,411,677 629 Agency-backed securities 117,403 — 117,403 — Corporate notes and other 467,244 — 467,244 — Total investment securities available-for-sale 3,558,870 — 3,558,241 629 Other investments 153,011 — 22,029 130,982 Other assets 190,629 — 190,629 — Total assets at fair value $ 3,902,510 $ — $ 3,770,899 $ 131,611 Other liabilities $ 96,483 $ — $ 96,483 $ — Total liabilities at fair value $ 96,483 $ — $ 96,483 $ — The following table presents assets measured at fair value on a nonrecurring basis as of September 30, 2023 and December 31, 2022 (in thousands): September 30, 2023 Total carrying value in the consolidated balance sheet Quoted market prices in an active market Models with significant observable market parameters Models with significant unobservable market Other real estate owned $ 2,555 $ — $ — $ 2,555 Collateral dependent loans (1) 60,284 — — 60,284 Total $ 62,839 $ — $ — $ 62,839 December 31, 2022 Other real estate owned $ 7,952 $ — $ — $ 7,952 Collateral dependent loans (1) 33,767 — — 33,767 Total $ 41,719 $ — $ — $ 41,719 (1) The carrying values of collateral dependent loans at September 30, 2023 and December 31, 2022 are net of valuation allowances of $10.5 million and $6.5 million, respectively. In the case of the available-for-sale 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 nine months ended September 30, 2023, 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 nine months ended September 30, 2023 and 2022 (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): For the Three months ended September 30, For the Nine months ended September 30, 2023 2022 2023 2022 Available-for-sale Securities Other Available-for-sale Securities Other Available-for-sale Securities Other Available-for-sale Securities Other Fair value, beginning of period $ 479 $ 151,762 $ 656 $ 121,611 $ 629 $ 130,982 $ 828 $ 100,996 Total realized gains included in income 1 (77) 2 725 3 3,597 5 9,104 Changes in unrealized gains/losses included in other comprehensive income (loss) (9) — (28) — (2) — (45) — Purchases — 8,015 — 8,481 — 27,947 — 27,244 Issuances — — — — — — — — Settlements — (3,037) — (5,638) (159) (5,863) (158) (12,165) Transfers out of Level 3 — — — — — — — — Fair value, end of period $ 471 $ 156,663 $ 630 $ 125,179 $ 471 $ 156,663 $ 630 $ 125,179 Total realized gains included in income $ 1 $ (77) $ 2 $ 725 $ 3 $ 3,597 $ 5 $ 9,104 The following tables present the carrying amounts, estimated fair value and placement in the fair value hierarchy of Pinnacle Financial's financial instruments at September 30, 2023 and December 31, 2022.

Regulatory Matters	Sep. 30, 2023
Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Matters	Note 11. 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. Additionally, approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of Pinnacle Bank to fall below specified minimum levels. 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 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 2.5% 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 nine months ended September 30, 2023, Pinnacle Bank paid $79.5 million of dividends to Pinnacle Financial. As of September 30, 2023, based on the criteria noted above Pinnacle Bank could pay approximately $1.3 billion of additional dividends to Pinnacle Financial. 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 18, 2022 when the board of directors increased the dividend to $0.22 per common share from $0.18 per common share. During the second quarter of 2020, 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 (and associated depositary shares), 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”), was delayed until December 31, 2021. As of January 1, 2022, the cumulative amount of the transition adjustments became fixed and is being 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 September 30, 2023, 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.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation — The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with U.S. 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, 2022 (2022 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 12. 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 intangible assets could change as a result of the uncertainty in current macroeconomic conditions. The resulting change in these estimates could be material to Pinnacle Financial's consolidated financial statements. Allowance for Credit Losses - Loans — Pinnacle Financial adopted FASB ASC 326, Financial Instruments - Credit Losses , effective January 1, 2020, which requires the estimation of an allowance for credit losses in accordance with the Current Expected Credit Losses (CECL) methodology. 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 a 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 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 through provision for credit losses and decreased by charge-offs, net of recoveries of amounts previously charged-off. During the second quarter of 2023, Pinnacle Financial implemented updated CECL models in an effort to ensure that risk in its portfolio at an individual loan level continues to be adequately captured given the uncertain state of the economy. The implementation of the new model had no material effect on the overall allowance for credit losses in the quarter of implementation. The allowance for credit losses is measured on a collective basis for pools of loans with similar risk characteristics. Pinnacle Financial has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses: • 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 granted under the Paycheck Protection Program (PPP), which are fully guaranteed by the Small Business Administration (SBA), are included in this category. • 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. For commercial real estate, consumer real estate, construction and land development, and commercial and industrial loans, Pinnacle Financial primarily utilizes a probability of default (PD) and loss given default (LGD) modeling approach. These models utilize historical correlations between default experience, loan level attributes and certain macroeconomic factors as determined through a statistical regression analysis. All loan segments modeled using this approach incorporate one or more macroeconomic drivers. Macroeconomic factors used in the model include the unadjusted and seasonally adjusted unemployment rate, gross domestic product, commercial property price index, consumer credit, commercial real estate price index, household debt ratio, household financial obligations ratio, and certain home price indices. Projections of these macroeconomic factors, obtained from an independent third party, are utilized to predict quarterly rates of default based on the statistical PD models. Adjustments are made to predicted default rates as considered necessary for each loan segment based on other quantitative and qualitative information not utilized as a direct input into the statistical models. The predicted quarterly default rates are then applied to the estimated future exposure at default (EAD), as determined based on contractual amortization terms and estimated prepayments. An estimated LGD, determined based on historical loss experience, is applied to the quarterly defaulted balances for each loan segment to estimate future losses of the loan's amortized cost. 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 September 30, 2023, a reasonable and supportable period of eighteen months was utilized for all loan segments, followed by a twelve month straight line reversion to long term averages. For the consumer and other loan segment, a loss rate approach is utilized. For these loans, historical charge off rates are applied to projected future balances, as determined in the same manner as EAD for the statistically modeled loan segments. For credit cards, which have no amortization terms or contractual maturities and are unconditionally cancellable, future balances are estimated based on expected payment volume applied to the current balance. The estimated loan losses for all loan segments are adjusted for changes in qualitative factors not inherently considered in the quantitative analyses. The qualitative categories and the measurements used to quantify the risks within each of these categories are subjectively selected by management but measured by objective measurements period over period. The data for each measurement may be obtained from internal or external sources. The current period measurements are evaluated and assigned a factor commensurate with the current level of risk relative to past measurements over time. The resulting qualitative adjustments are applied to the relevant collectively evaluated loan portfolios. These adjustments are based upon quarterly trend assessments in portfolio concentrations, policy exceptions, associate retention, independent loan review results, 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. Additional qualitative considerations are made for any identified risk which did not exist within our portfolio historically and therefore may not be adequately addressed through evaluation of such risk factor based on historical portfolio trends as previously discussed. 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. For loans individually evaluated for which repayment is expected to be provided substantially through the operation or sale of the collateral, Pinnacle Financial has elected the practical expedient under ASC 326 to estimate expected credit losses based on the fair value of the collateral, with selling costs considered in the event sale of the collateral is expected. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. Pinnacle Financial uses a probability of default/loss given default model to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. Occasionally, a loan modification will be granted by providing principal forgiveness on certain loans. When principal forgiveness is provided, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. In some cases, a loan restructuring will result in providing multiple types of modifications. Typically, one type of modification, such as a payment delay or term extension, is granted initially. If the borrower continues to experience financial difficulty, another modification, such as principal forgiveness or an interest rate reduction, may be granted. Additionally, multiple types of modifications may be made on the same loan within the current reporting period. Such a combination is at least two of the following: a payment delay, term extension, principal forgiveness, and interest rate reduction. Upon determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. In assessing the adequacy of the allowance for credit losses, Pinnacle Financial considers the results of Pinnacle Financial's ongoing independent loan review process. Pinnacle Financial undertakes this process both to ascertain those loans in the portfolio with elevated credit risk and to assist in its overall evaluation of the risk characteristics of the entire loan portfolio. Its loan review process includes the judgment of management, independent internal loan reviewers and reviews that may have been conducted by third-party reviewers including regulatory examiners. Pinnacle Financial incorporates relevant loan review results in the allowance. While policies and procedures used to estimate the allowance for credit losses, as well as the resultant provision for credit losses charged to income, are considered adequate by management and are reviewed periodically by regulators, model validators and internal auditors, they are necessarily approximate and imprecise. There are factors beyond Pinnacle Financial's control, such as changes in projected economic conditions, real estate markets or particular industry conditions which may materially impact asset quality and the adequacy of the allowance for credit losses and thus the resulting provision for credit losses. Other than the changes noted above under the section titled " Allowance for Credit Losses - Loans"
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, including those with performance-based vesting provisions. 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 nine months ended September 30, 2023 and 2022 (in thousands, except per share data): Three months ended Nine months ended 2023 2022 2023 2022 Basic net income per common share calculation: Numerator - Net income available to common shareholders $ 128,805 $ 144,860 $ 455,779 $ 411,501 Denominator - Weighted average common shares outstanding 76,044 75,762 75,999 75,723 Basic net income per common share $ 1.69 $ 1.91 $ 6.00 $ 5.43 Diluted net income per common share calculation: Numerator - Net income available to common shareholders $ 128,805 $ 144,860 $ 455,779 $ 411,501 Denominator - Weighted average common shares outstanding 76,044 75,762 75,999 75,723 Dilutive common shares contingently issuable 158 217 104 222 Weighted average diluted common shares outstanding 76,202 75,979 76,103 75,945 Diluted net income per common share $ 1.69 $ 1.91 $ 5.99 $ 5.42
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements — 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 was initially effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued an update to Accounting Standards Update 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting with Accounting Standards Update 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which updated the effective date to be March 12, 2020 through December 31, 2024. Pinnacle Financial implemented a transition plan to identify and convert its loans and other financial instruments, including certain indebtedness, with attributes that are either directly or indirectly influenced by LIBOR. Pinnacle Financial has moved the majority of its LIBOR-based loans to its preferred replacement index, a Secured Overnight Financing Rate (SOFR) based index as of September 30, 2023. For Pinnacle Financial's currently outstanding LIBOR-based loans, the timing and manner in which each customer's interest rate transitions to a replacement index will vary on a case-by-case basis and should occur at the next repricing date for these loans. In March 2022, the FASB issued Accounting Standards Update 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method , which allows multiple hedged layers to be designated for a single closed portfolio of financial assets resulting in a greater portion of the interest rate risk in the closed portfolio being eligible to be hedged. The amendments allow the flexibility to use different types of derivatives or combinations of derivatives to better align with risk management strategies. Furthermore, among other things, the amendments clarify that basis adjustments of hedged items in the closed portfolio should be allocated at the portfolio level and not the individual assets within the portfolio. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Pinnacle Financial adopted ASU 2022-01 on January 1, 2023 and it did not impact Pinnacle Financial's accounting or disclosures. In March 2022, the FASB issued Accounting Standards Update 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , which removes the accounting guidance for troubled debt restructurings and requires entities to evaluate whether a modification provided to a borrower results in a new loan or continuation of an existing loan. The amendments enhance existing disclosures and require new disclosures for receivables when there has been a modification in contractual cash flows due to a borrower experiencing financial difficulties. Additionally, the amendments require public business entities to disclose gross charge-off information by year of origination in the vintage disclosures. The guidance is effective for entities that have adopted ASU 2016-13 for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Pinnacle Financial adopted ASU 2022-02 on January 1, 2023 and incorporated the required disclosures into Note 4. Loans and Allowance for Credit Losses .
Newly Issued Not Yet Effective Accounting Standards	Newly Issued Not Yet Effective Accounting Standards — In June 2022, the FASB issued Accounting Standards Update 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , which clarifies the guidance in ASC 820 when measuring the fair value of equity securities subject to contractual restrictions that prohibit the sale of an equity security. This update also requires specific disclosures related to these types of securities. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted, including early adoption in an interim period. An entity should apply ASU 2022-03 prospectively once adopted. Pinnacle Financial is assessing ASU 2022-03 and its potential impact on its accounting and disclosures. In March 2023, the FASB issued Accounting Standards Update 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method , which permits the use of the proportional amortization method of accounting for tax equity investments if certain conditions are met. A reporting entity makes the accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity or individual investment level. The amendments require specific disclosures that must be applied to all investments that generate tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted, including early adoption in an interim period. An entity should apply ASU 2023-02 on a retrospective or modified retrospective basis once adopted. Pinnacle Financial is assessing ASU 2023-02 and its potential impact on its accounting and disclosures. Other than those pronouncements discussed above and those which have been recently adopted, Pinnacle Financial does not believe there were any other recently issued accounting pronouncements that may materially impact its consolidated financial statements.
Reclassifications	Reclassifications — Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholder's equity.
Subsequent Events	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 September 30, 2023 through the date of the issued financial statements with no subsequent events being noted as of the date of this filing.

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 nine months ended September 30, 2023. The table reflects the life-to-date activity for these awards: Grant Group (1) Vesting Shares Restrictions lapsed and shares released to participants Shares withheld for taxes by participants Shares forfeited by participants (4) Shares unvested Time Based Awards 2023 Associates (2) 5 229,058 270 152 6,358 222,278 Outside Director Awards (3) 2023 Outside directors 1 10,840 — — — 10,840 (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, 2024 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 September 30, 2023. 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.

Summary of Interest Rate Swaps	A summary of Pinnacle Financial's interest rate swaps to facilitate customers' transactions as of September 30, 2023 and December 31, 2022 is included in the following table (in thousands): September 30, 2023 December 31, 2022 Notional Estimated Fair Value (1) Notional Estimated Fair Value (1) Interest rate swap agreements: Assets $ 1,886,702 $ 117,072 $ 1,620,520 $ 39,763 Liabilities 1,886,702 (118,367) 1,620,520 (96,483) Total $ 3,773,404 $ (1,295) $ 3,241,040 $ (56,720) (1) The variation margin payments for derivatives cleared through central clearing houses are characterized as settlements. At September 30, 2023, there were no interest rate swap agreements designated as non-hedge derivatives cleared through clearing houses. At December 31, 2022, the notional amount of interest rate swap agreements designated as non-hedge derivatives cleared through clearing houses was $827.3 million with a fair value that approximates zero due to $56.3 million in received variation margin payments. The effects of Pinnacle Financial's interest rate swaps to facilitate customers' transactions on the income statement during the three and nine months ended September 30, 2023 and 2022 were as follows (in thousands): Amount of Gain (Loss) Recognized in Income Location of Gain (Loss) Recognized in Income Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 Interest rate swap agreements Other noninterest income $ (265) $ (207) $ (847) $ 34
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 the cash flow hedge relationships as of September 30, 2023 and December 31, 2022 is as follows (in thousands): September 30, 2023 December 31, 2022 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Receive Rate Pay Rate Notional Amount Estimated Fair Value Notional Amount Estimated Fair Value Asset derivatives Interest rate floor - loans Other assets 4.09 4.00%-4.50% minus USD-Term SOFR 1M N/A $ 875,000 $ 25,225 $ 875,000 $ 48,622 Interest rate collars - loans Other assets 4.09 4.25%-4.75% minus USD-Term SOFR 1M USD-Term SOFR 1M minus 6.75%-7.00% 875,000 23,745 875,000 45,553 $ 1,750,000 $ 48,970 $ 1,750,000 $ 94,175 The effects of Pinnacle Financial's cash flow hedge relationships on the statement of comprehensive income (loss) during the three and nine months ended September 30, 2023 and 2022 were as follows, net of tax (in thousands): Amount of Loss Recognized Three Months Ended September 30, Nine Months Ended September 30, Asset derivatives 2023 2022 2023 2022 Interest rate floors and collars - loans $ (17,403) $ — $ (28,764) $ — 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 $2.5 million and $7.2 million, net of tax, were reclassified from accumulated other comprehensive income (loss) into net income during the three and nine months ended September 30, 2023, respectively, compared to $2.5 million and $7.5 million, net of tax, during the three and nine months ended September 30, 2022, respectively. Approximately $9.8 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 federal funds rates or SOFR. 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. In March 2023, Pinnacle Financial entered into fair value hedges with aggregate notional amounts of $425.0 million to mitigate the effect of changing interest rates on FHLB Cincinnati (FHLB) advances with payments beginning in the first quarter of 2024. In May 2023, Pinnacle Financial entered into additional fair value hedges with aggregate notional amounts of $425.0 million to mitigate the effect of changing interest rates on FHLB advances with payments beginning in the fourth quarter of 2024 and first quarter of 2025.

At September 30, 2023 and December 31, 2022, the notional amount of fair value derivatives cleared through central clearing houses was $1.9 billion and $877.7 million with a fair value that approximates zero due to $80.6 million and $47.9 million in received variation margin. Notional amounts of $392.2 million as of September 30, 2023 receive a variable rate of interest based on the daily compounded federal funds rate and notional amounts totaling $1.6 billion as of September 30, 2023 receive a variable rate of interest based on the daily compounded SOFR. Notional amounts receiving a variable rate of interest based on three month LIBOR transitioned to three month SOFR plus a comparable tenor spread adjustment on future rate adjustment dates occurring after June 30, 2023.

[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 loan modifications made to borrowers experiencing financial difficulty. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $134.5 million at September 30, 2023, compared to $53.8 million at December 31, 2022.

[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 September 30, 2023. 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, 2024 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.
