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 acquisitions of Advocate Capital, Inc. (Advocate Capital) and JB&B Capital, LLC (JB&B) on July 2, 2019 and March 1, 2022, respectively. 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 providers and other skilled professionals for business purposes but also makes consumer loans for various purposes. Pinnacle Bank provides a full range of banking services, including investment, mortgage, insurance, and comprehensive wealth management services, in several primarily urban markets and their surrounding communities. 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, 2023 (2023 10-K). These unaudited consolidated financial statements include the accounts of Pinnacle Financial and its wholly-owned subsidiaries. Certain statutory trust affiliates of Pinnacle Financial, as noted in Note 11. Other Borrowings, are included in these unaudited 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. Mortgage Servicing Rights — On March 31, 2024, Pinnacle Financial recognized a mortgage servicing asset totaling $11.8 million related to a commercial mortgage loan portfolio. Upon the sale of these commercial loans, the rights to service loans (MSRs) are capitalized and represent the fair value of future net servicing fees from servicing activities associated with these commercial mortgage loans. Pinnacle Financial has elected to account for this class of MSRs under the fair value measurement method. Under this method, capitalized MSRs will be recorded in other assets in the accompanying consolidated balance sheet with changes in the fair value of the MSRs for each period presented recorded in other noninterest income in the accompanying consolidated statement of income. MSRs are recorded at fair value utilizing a number of assumptions, including prepayment speeds, interest rates, discount rates and other economic factors. Changes in the underlying assumptions could materially affect the fair value of MSRs. The value of servicing rights is initially measured using a discounted cash flow model. All servicing rights capitalized have involved the retention of servicing rights only; Pinnacle Financial does not retain residual interest, "first loss" obligations, or other similar on-going financial interests in the loans it sells to third parties, nor has Pinnacle Financial participated in any securitizations with any special purpose entities with respect to these MSRs. Except for recovery of amounts invested in acquiring servicing rights, servicing mortgage loans for others does not generally impose significant financial risks to the servicer. There are, however, certain investors for whom servicing does involve some risk of loss. For example, servicing Federal Housing Administration insured or Veterans Administration guaranteed loans can result in the servicer advancing principal and interest payments for delinquent borrowers, or incurring a shortfall in the total amount of principal collected under certain foreclosure circumstances. Cash Flow Information — Supplemental cash flow information addressing certain cash and noncash transactions for the three months ended March 31, 2024 and 2023 was as follows (in thousands): For the three months ended 2024 2023 Cash Transactions: Interest paid $ 341,042 $ 181,254 Income taxes paid, net 1,216 5,121 Operating lease payments 9,142 4,700 Noncash Transactions: Loans charged-off to the allowance for credit losses 20,832 14,022 Loans foreclosed upon and transferred to other real estate owned 435 150 Right-of-use asset recognized during the period in exchange for lease obligations 5,673 3,603 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 months ended March 31, 2024 and 2023 (in thousands, except per share data): Three months ended 2024 2023 Basic net income per common share calculation: Numerator - Net income available to common shareholders $ 120,146 $ 133,473 Denominator - Weighted average common shares outstanding 76,278 75,921 Basic net income per common share $ 1.58 $ 1.76 Diluted net income per common share calculation: Numerator - Net income available to common shareholders $ 120,146 $ 133,473 Denominator - Weighted average common shares outstanding 76,278 75,921 Dilutive common shares contingently issuable 151 121 Weighted average diluted common shares outstanding 76,429 76,042 Diluted net income per common share $ 1.57 $ 1.76 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 the London Interbank Offered Rate (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 substantially all of its LIBOR-based loans to its preferred replacement index, a Secured Overnight Financing Rate (SOFR) based index as of March 31, 2024. 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 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. Pinnacle Financial adopted ASU 2022-03 on January 1, 2024 and it did not have a material impact on Pinnacle Financial's accounting or 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. Pinnacle Financial adopted ASU 2023-02 on January 1, 2024 and it did not have a material impact on Pinnacle Financial's accounting or disclosures. Newly Issued Not Yet Effective Accounting Standards — In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which amends the guidance for income tax disclosures to include certain required disclosures related to tax rate reconciliations, including certain categories of expense requiring disclosure, income taxes paid, including disclosure of taxes paid disaggregated by nation, state, and foreign taxes, and other disclosures for disaggregation of income before income tax expense (or benefit) and income tax expense (or benefit) by domestic and foreign allocation. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2024. Early adoption is permitted. An entity should apply ASU 2023-09 on a prospective basis once adopted with retrospective application permitted. Pinnacle Financial is assessing ASU 2023-09 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. 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 March 31, 2024 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, on these transferred securities 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 March 31, 2024, approximately $2.0 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 March 31, 2024, repurchase agreements comprised of secured borrowings totaled $201.4 million and were secured by $201.4 million of pledged U.S. government agency securities, mortgage-backed securities, municipal securities, asset-backed securities and corporate notes. 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 March 31, 2024 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 March 31, 2024: Amortized Fair Amortized Fair Due in one year or less $ 27,863 $ 29,143 $ 95,418 $ 92,840 Due in one year to five years 241,765 236,003 372,318 347,867 Due in five years to ten years 506,600 462,247 91,872 84,791 Due after ten years 2,511,647 2,459,445 1,859,490 1,683,161 Mortgage-backed securities 1,095,839 970,212 378,228 339,269 Asset-backed securities 230,109 221,668 197,511 185,131 $ 4,613,823 $ 4,378,718 $ 2,994,837 $ 2,733,059 At March 31, 2024 and December 31, 2023, 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 March 31, 2024 and December 31, 2023, 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 March 31, 2024, Pinnacle Financial had approximately $262.8 million in unrealized losses on approximately $3.2 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 March 31, 2024, 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 March 31, 2024 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 March 31, 2024. 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 twenty-four months with an eight month reversion to average loss factors. At both March 31, 2024 and December 31, 2023, the estimated allowance for credit losses on these held-to-maturity securities was $1.7 million. Pinnacle Financial utilizes bond credit ratings assigned by third party ratings agencies to monitor the credit quality of debt securities held-to-maturity. At March 31, 2024, 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 months ended March 31, 2024 and 2023, no available-for-sale securities were sold. Pinnacle Financial has entered into various fair value hedging transactions to mitigate the impact of changing interest rates on the fair values of available-for-sale securities. See Note 8. Derivative Instruments for disclosure of the gains and losses recognized on derivative instruments and the cumulative fair value hedging adjustments to the carrying amount of the hedged securities.

Receivables [Abstract]
Loans and Allowance for Credit Losses	Note 4. Loans and Allowance for Credit Losses For financial reporting purposes, Pinnacle Financial classifies its loan portfolio based on the underlying collateral utilized to secure each loan. This classification is consistent with those utilized in the Quarterly Report of Condition and Income filed by Pinnacle Bank with the Federal Deposit Insurance Corporation (FDIC). Pinnacle Financial uses the following loan categories for presentation of loan balances and the related allowance for credit losses on loans: • Owner occupied commercial real estate mortgage loans - Owner occupied commercial real estate mortgage loans are secured by commercial office buildings, industrial buildings, warehouses or retail buildings where the owner of the building occupies the property. For such loans, repayment is largely dependent upon the operation of the borrower's business. • Non-owner occupied commercial real estate loans - These loans represent investment real estate loans secured by office buildings, industrial buildings, warehouses, retail buildings, and multifamily residential housing. Repayment is primarily dependent on lease income generated from the underlying collateral. • Consumer real estate mortgage loans - Consumer real estate mortgage consists primarily of loans secured by 1-4 family residential properties, including home equity lines of credit. Repayment is primarily dependent on the personal cash flow of the borrower. • Construction and land development loans - Construction and land development loans include loans where the repayment is dependent on the successful completion and eventual sale, refinance or operation of the related real estate project. Construction and land development loans include 1-4 family construction projects and commercial construction endeavors such as warehouses, apartments, office and retail space and land acquisition and development. • Commercial and industrial loans - Commercial and industrial loans include loans to business enterprises issued for commercial, industrial and/or other professional purposes. These loans are generally secured by equipment, inventory, and accounts receivable of the borrower and repayment is primarily dependent on business cash flows. • 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 March 31, 2024 and December 31, 2023 were as follows (in thousands): March 31, 2024 December 31, 2023 Commercial real estate: Owner occupied $ 4,044,973 $ 4,044,896 Non-owner occupied 8,063,642 7,535,494 Consumer real estate – mortgage 4,828,416 4,851,531 Construction and land development 3,818,334 4,041,081 Commercial and industrial 11,893,198 11,666,691 Consumer and other 514,310 536,398 Subtotal $ 33,162,873 $ 32,676,091 Allowance for credit losses (371,337) (353,055) Loans, net $ 32,791,536 $ 32,323,036 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 March 31, 2024, approximately 79.6% 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 that 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 following tables present loan balances classified within each risk rating category by primary loan type and year of origination or most recent renewal as of March 31, 2024 and December 31, 2023, as well as the gross loan charge-offs by primary loan type and year of origination or most recent renewal for the three months ended March 31, 2024 (in thousands): 2024 2023 2022 2021 2020 Prior Revolving Loans Total March 31, 2024 Commercial real estate -

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. 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. 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. 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 fifteen months was utilized for all loan segments at March 31, 2024 and December 31, 2023, 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 March 31, 2024 and December 31, 2023 (in thousands): Real Estate Business Assets Other Total March 31, 2024 Commercial real estate: Owner occupied $ 23,726 $ — $ — $ 23,726 Non-owner occupied 68,615 — — 68,615 Consumer real estate – mortgage 26,055 — — 26,055 Construction and land development 759 — — 759 Commercial and industrial — 38,056 551 38,607 Consumer and other — — 65 65 Total $ 119,155 $ 38,056 $ 616 $ 157,827 December 31, 2023 Commercial real estate: Owner occupied $ 22,284 $ — $ — $ 22,284 Non-owner occupied 69,577 — — 69,577 Consumer real estate – mortgage 20,389 — — 20,389 Construction and land development 668 — — 668 Commercial and industrial — 31,625 552 32,177 Consumer and other — — — — Total $ 112,918 $ 31,625 $ 552 $ 145,095 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 charged 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.

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 months ended March 31, 2024 and 2023, respectively. Had these loans been on accruing status, an additional $2.6 million and $1.1 million of interest income would have been recognized for the three months ended March 31, 2024 and 2023, respectively. Approximately $31.2 million and $7.9 million of nonaccrual loans were performing pursuant to their contractual terms as of March 31, 2024 and December 31, 2023, 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 March 31, 2024 with the comparative exposures for December 31, 2023 (in thousands): March 31, 2024 Outstanding Principal Balances Unfunded Commitments Total exposure Total Exposure at December 31, 2023 Lessors of nonresidential buildings $ 4,784,990 $ 1,134,125 $ 5,919,115 $ 5,916,335 Lessors of residential buildings 2,164,633 967,350 3,131,983 3,179,041 New Housing For-Sale Builders 603,969 746,691 1,350,660 1,396,653 Music Publishers 839,813 438,738 1,278,551 1,219,781 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 March 31, 2024 and December 31, 2023, Pinnacle Bank’s construction and land development loans as a percentage of total risk-based capital were 77.5% and 84.2%, 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 258.0% and 259.0% as of March 31, 2024 and December 31, 2023, 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 March 31, 2024, 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 March 31, 2024, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $37.6 million to current directors, executive officers, and their related interests, of which $34.4 million had been drawn upon. At December 31, 2023, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $37.7 million to directors, executive officers, and their related interests, of which approximately $34.7 million had been drawn upon. All loans to directors, executive officers, and their related interests were performing in accordance with contractual terms at March 31, 2024 and December 31, 2023. Loans Held for Sale At March 31, 2024, Pinnacle Financial had approximately $6.1 million in commercial loans held for sale compared to $9.3 million at December 31, 2023. 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 por

Income Tax Disclosure [Abstract]
Income Taxes	Note 5. Income Taxes ASC 740, Income Taxes , defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authority. This section also provides guidance on the derecognition, measurement and classification of income tax uncertainties, along with any related interest and penalties, and includes guidance concerning accounting for income tax uncertainties in interim periods. The unrecognized tax benefit related to uncertain tax positions related to state income tax filings was $8.8 million at March 31, 2024 and December 31, 2023, respectively. During the three months ended March 31, 2024, Pinnacle Financial paid $3,000 in taxes related to state income tax filings for tax years prior to 2024. During the three months ended March 31, 2023, Pinnacle Financial paid $4.2 million in taxes related to state income tax filings for tax years prior to 2023. 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 months ended March 31, 2024 and March 31, 2023. Pinnacle Financial's effective tax rate for the three months ended March 31, 2024 was 18.1% compared to 19.8% for the three months ended March 31, 2023. The difference between the effective tax rate and the federal and state income tax statutory rate of 25.00% at March 31, 2024 and 2023, 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 and bank-owned life insurance, 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 months ended March 31, 2024 and 2023, Pinnacle Financial recognized excess tax benefits of $2.4 million and $277,000, respectively, with respect to the vesting of equity-based awards and the exercise of employee stock options.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Note 6. Commitments and Contingent Liabilities In the normal course of business, Pinnacle Financial has entered into off-balance sheet financial instruments which include commitments to extend credit (i.e., including unfunded lines of credit) and standby letters of credit. Commitments to extend credit are usually the result of lines of credit granted to existing borrowers under agreements that the total outstanding indebtedness will not exceed a specific amount during the term of the indebtedness. Typical borrowers are commercial concerns that use lines of credit to supplement their treasury management functions, thus their total outstanding indebtedness may fluctuate during any time period based on the seasonality of their business and the resultant timing of their cash flows. Other typical lines of credit are related to home equity loans granted to consumers. Commitments to extend credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. At March 31, 2024, these commitments amounted to $14.8 billion, of which approximately $1.9 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 March 31, 2024 and December 31, 2023, these commitments amounted to $349.5 million and $325.1 million, respectively. 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 both March 31, 2024 and December 31, 2023, Pinnacle Financial had accrued reserves of $17.5 million for the inherent risks associated with these off-balance sheet commitments. There was no provision for these unfunded commitments for the three months ended March 31, 2024 as compared to a benefit of $2.0 million during the three months ended March 31, 2023. 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 March 31, 2024 are not expected to have a material adverse impact on Pinnacle Financial's consolidated financial condition, operating results or cash flows.

Share-Based Payment Arrangement [Abstract]
Stock Options and Restricted Shares	Note 7. Equity Compensation 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 March 31, 2024, there were approximately 712,000 shares available for issuance under the 2018 Plan. On April 23, 2024, Pinnacle Financial's common shareholders approved an amendment and restatement of the 2018 Plan that, among other things, authorized an additional 1,000,000 shares for issuance under the 2018 Plan. Restricted Share Awards A summary of activity for unvested restricted share awards for the three months ended March 31, 2024 is as follows: Number Grant Date Unvested at December 31, 2023 703,399 $ 77.68 Shares awarded 199,791 Restrictions lapsed and shares released to associates/directors (164,428) Shares forfeited (10,095) Unvested at March 31, 2024 728,667 $ 80.26 Pinnacle Financial has granted restricted share awards to associates (including certain members of executive management) 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 three months ended March 31, 2024. 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 2024 Associates (2) 5 189,901 10 15 2,199 187,677 Outside Director Awards (3) 2024 Outside directors 1 9,890 — — — 9,890 (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, 2025 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 was terminated during the year-to-date period ended March 31, 2024. 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 three months ended March 31, 2024 is as follows: Number Grant Date Unvested at December 31, 2023 102,877 $ 78.03 Shares awarded 57,480 Restrictions lapsed and shares released to associates (49,185) Shares forfeited (658) Unvested at March 31, 2024 110,514 $ 80.84 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 three months ended March 31, 2024. 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 2024 3 57,480 — — 180 57,300 (1) These shares represent forfeitures resulting from recipients whose employment was terminated during the year-to-date period ended March 31, 2024. 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 March 31, 2024: 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) 2024 80,211 — 192,499 53,710 2024-2026 0 0 2027 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 2020 136,137 — 204,220 59,648 2020 2 3 2025 2021 2 2 2025 2022 2 1 2025 (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 three months ended March 31, 2024 and 2023, the restrictions associated with 435,881 and 111,108 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, and were settled into shares of Pinnacle Financial common stock with 158,117 and 38,782 shares, respectively, 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 months ended March 31, 2024 was $10.3 million compared to $10.2 million for the three months ended March 31, 2023. As of March 31, 2024, 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 $86.0 million. This expense, if the underlying units are earned, is expected to be recognized over a weighted-average period of 2.10 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 8. Derivative Instruments Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship and classification as either a cash flow hedge or fair value hedge for those derivatives which are designated as part of a hedging relationship. 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 March 31, 2024 and December 31, 2023. 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 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 March 31, 2024 and December 31, 2023 is included in the following table (in thousands): March 31, 2024 December 31, 2023 Notional Estimated Fair Value (1) Notional Estimated Fair Value (1) Interest rate swap agreements: Assets $ 2,122,251 $ 82,743 $ 2,037,740 $ 66,462 Liabilities 2,122,251 (83,663) 2,037,740 (67,206) Total $ 4,244,502 $ (920) $ 4,075,480 $ (744) (1) The variation margin payments for derivatives cleared through central clearing houses are characterized as settlements. At March 31, 2024 and December 31, 2023, there were no interest rate swap agreements designated as non-hedge derivatives cleared through clearing houses. The effects of Pinnacle Financial's interest rate swaps to facilitate customers' transactions on the income statement during the three months ended March 31, 2024 and 2023 were as follows (in thousands): Amount of Loss Recognized in Income Location of Loss Recognized in Income Three Months Ended March 31, 2024 2023 Interest rate swap agreements Other noninterest income $ (178) $ (63) 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 March 31, 2024 and December 31, 2023 is as follows (in thousands): March 31, 2024 December 31, 2023 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 3.59 4.00%-4.50% minus USD-Term SOFR 1M N/A $ 875,000 $ 22,466 $ 875,000 $ 36,483 Interest rate collars - loans Other assets 3.59 4.25%-4.75% minus USD-Term SOFR 1M USD-Term SOFR 1M minus 6.75%-7.00% 875,000 23,463 875,000 38,314 $ 1,750,000 $ 45,929 $ 1,750,000 $ 74,797 The effects of Pinnacle Financial's cash flow hedge relationships on the statement of comprehensive income (loss) during the three months ended March 31, 2024 and 2023 were as follows, net of tax (in thousands): Amount of Gain (Loss) Recognized Three Months Ended March 31, Asset derivatives 2024 2023 Interest rate floors and collars - loans $ (19,646) $ 11,978 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, net of tax, were reclassified from accumulated other comprehensive income (loss) into net income during the three months ended March 31, 2024 and 2023, respectively. Approximately $6.5 million in unrealized gains, net of tax, are expected to be reclassified from accumulated other comprehensive income (loss) into net income over the next twelve months related to previously terminated cash flow hedges. Derivatives designated as fair value hedges For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. Pinnacle Financial utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable available-for-sale securities. The hedging strategy converts the fixed interest rates to variable interest rates based on 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. Pinnacle Financial also utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on FHLB advances with payments beginning on various dates throughout 2024 and the first quarter of 2025. A summary of Pinnacle Financial's fair value hedge relationships as of March 31, 2024 and December 31, 2023 is as follows (in thousands): March 31, 2024 December 31, 2023 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 10.70 2.81% Federal Funds/ SOFR $ 2,112,139 $ 68,520 $ 543,061 $ 42,983 Interest rate swaps - borrowings Other assets N/A N/A N/A — — 750,000 3,654 Liability derivatives Interest rate swaps - securities Other liabilities N/A N/A N/A $ — $ — $ 1,569,078 $ (1,275) Interest rate swaps - borrowings Other liabilities 3.48 5.33% SOFR 1,175,000 (23,963) 425,000 (1,656) $ 3,287,139 $ 44,557 $ 3,287,139 $ 43,706 (1) The variation margin payments for derivatives cleared through central clearing houses are characterized as settlements. At March 31, 2024 and December 31, 2023, the notional amount of fair value derivatives cleared through central clearing houses was $2.0 billion with a fair value that approximates zero due to $27.8 million and $4.0 million in variation margin payments. Notional amounts of $392.2 million as of March 31, 2024 receive a variable rate of interest based on the daily compounded federal funds rate and notional amounts totaling $2.9 billion as of March 31, 2024 receive a variable rate of interest based on the daily compounded SOFR.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 9. 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. Mortgage Servicing Rights – On March 31, 2024, Pinnacle Financial recognized a mortgage servicing asset totaling $11.8 million related to a commercial mortgage loan portfolio. Upon the sale of these commercial loans, the MSRs are capitalized and represent the fair value of future net servicing fees from servicing activities associated with these commercial mortgage loans. Pinnacle Financial has elected to account for this class of MSRs under the fair value measurement method. Fair value for MSRs is determined utilizing a discounted cash flow model which calculates the fair value of each servicing right based on the present value of the expected cash flows from servicing revenues less servicing costs of the portfolio. The valuation of MSRs uses assumptions market participants would use in determining fair value including, including prepayment speeds, interest rates, discount rates and other economic factors, which are considered significant unobservable inputs. Due to the nature of the inputs used in the valuation, MSRs are classified within Level 3 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 March 31, 2024 and December 31, 2023, 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 March 31, 2024 Investment securities available-for-sale: U.S. Treasury securities $ 872,791 $ — $ 872,791 $ — U.S. Government agency securities 288,833 — 288,833 — Mortgage-backed securities 970,212 — 970,212 — State and municipal securities 1,592,783 — 1,592,451 332 Agency-backed securities 221,668 — 221,668 — Corporate notes and other 432,431 — 419,579 12,852 Total investment securities available-for-sale 4,378,718 — 4,365,534 13,184 Other investments 184,372 — 22,137 162,235 Mortgage servicing rights 11,812 — — 11,812 Other assets 209,530 — 209,530 — 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 assets at fair value $ 4,784,432 $ — $ 4,597,201 $ 187,231 Other liabilities $ 118,698 $ — $ 118,698 $ — Total liabilities at fair value $ 118,698 $ — $ 118,698 $ — December 31, 2023 Investment securities available-for-sale: U.S. Treasury securities $ 893,412 $ — $ 893,412 $ — U.S. Government agency securities 262,730 — 262,730 — Mortgage-backed securities 947,390 — 947,390 — State and municipal securities 1,585,895 — 1,585,416 479 Agency-backed securities 191,635 — 191,635 — Corporate notes and other 436,468 — 436,468 — Total investment securities available-for-sale 4,317,530 — 4,317,051 479 Other investments 179,487 — 22,347 157,140 Other assets 197,541 — 197,541 — Total assets at fair value $ 4,694,558 $ — $ 4,536,939 $ 157,619 Other liabilities $ 79,068 $ — $ 79,068 $ — Total liabilities at fair value $ 79,068 $ — $ 79,068 $ — The following table presents assets measured at fair value on a nonrecurring basis as of March 31, 2024 and December 31, 2023 (in thousands): March 31, 2024 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 $ 2,766 $ — $ — $ 2,766 Collateral dependent loans (1) 88,685 — — 88,685 Total $ 91,451 $ — $ — $ 91,451 December 31, 2023 Other real estate owned $ 3,937 $ — $ — $ 3,937 Collateral dependent loans (1) 52,167 — — 52,167 Total $ 56,104 $ — $ — $ 56,104 (1) The carrying values of collateral dependent loans at March 31, 2024 and December 31, 2023 are net of valuation allowances of $33.4 million and $18.6 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. During the three months ended March 31, 2024, one available-for-sale security previously classified as Level 2 was transferred to Level 3 due to unobservable inputs becoming significant. 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 three months ended March 31, 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 months ended March 31, 2024 and 2023 (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 March 31, 2024 2023 Available-for-sale securities Other Mortgage servicing rights Available-for-sale securities Other Fair value, beginning of period $ 479 $ 157,140 $ — $ 629 $ 130,982 Total realized gains (losses) included in income 13 (714) 11,812 1 2,360 Changes in unrealized gains/losses included in other comprehensive income (loss) 16 — — 8 — Transfers into Level 3 12,841 — — — — Purchases — 7,467 — — 9,202 Issuances — — — — — Settlements (165) (1,658) — (159) (1,534) Transfers out of Level 3 — — — — — Fair value, end of period $ 13,184 $ 162,235 $ 11,812 $ 479 $ 141,010 Total realized gains (losses) included in income $ 13 $ (714) $ 11,812 $ 1 $ 2,360 The following tables present the carrying amounts, estimated fair value and placement in the fair value hierarchy of Pinnacle Financial's financial instruments at March 31, 2024 and December 31, 2023. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash, cash equivalents, and restricted cash, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as non-interest bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity (in thousands): Carrying Amount Estimated Fair Value (1) Quoted market prices in an active market Models with significant observable market parameters Models with significant unobservable market March 31, 2024 Financial assets: Securities purchased with agreement to resell $ 554,022 $ 459,206 $ — $ — $ 459,206 Securities held-to-maturity 2,993,129 2,733,059 — 2,733,059 — Loans, net 32,791,536 32,086,768 — — 32,086,768 Consumer loans held-for-sale 104,586 105,060 — 105,060 — Commercial loans held-for-sale 6,068 6,096 — 6,096 — Financial liabilities: Deposits and securities sold under agreements to repurchase 39,603,443 38,791,572 — — 38,791,572 Federal Home Loan Bank advances 2,116,417 2,104,237 — — 2,104,237 Subordinated debt and other borrowings 425,159 462,835 — — 462,835 Carrying Amount Estimated Fair Value (1) Quoted market prices in an active market Models with significant observable market parameters Models with significant unobservable market December 31, 2023 Financial assets: Securities purchased with agreement to resell $ 558,009 $ 461,375 $ — $ — $ 461,375 Securities held-to-maturity 3,006,357 2,775,184 — 2,775,184 — Loans, net 32,323,036 31,863,583 — — 31,863,583 Consumer loans held-for-sale 104,217 104,626 — 104,626 — Commercial loans held-for-sale 9,280 9,316 — 9,316 — Financial liabilities: Deposits and securities sold under agreements to repurchase 38,749,299 37,954,938 — — 37,954,938 Federal Home Loan Bank advances 2,138,169 2,166,912 — — 2,166,912 Subordinated debt and other borrowings 424,938 462,399 — — 462,399 (1) Estimated fair values are consistent with an exit-price concept.

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Matters	Note 10. Regulatory Matters Pursuant to Tennessee banking law, Pinnacle Bank may not, without the prior consent of the Commissioner of the Tennessee Department of Financial Institutions (TDFI), pay any dividends to Pinnacle Financial in a calendar year in excess of the total of Pinnacle Bank's retained net income for that year plus the retained net income for the preceding two years. 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 three months ended March 31, 2024, Pinnacle Bank paid $26.7 million of dividends to Pinnacle Financial. As of March 31, 2024, based on the criteria noted above Pinnacle Bank could pay approximately $1.1 billion of additional dividends to Pinnacle Financial without prior approval of the Commissioner of the TDFI. Since the fourth quarter of 2013, Pinnacle Financial has paid a quarterly common stock dividend. The board of directors of Pinnacle Financial has increased the dividend amount per share over time. The most recent increase occurred on January 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, liquidity 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 will be phased out of the regulatory capital calculations evenly over a three year period, with 75% recognized in 2022, 50% recognized in 2023 and 25% recognized in 2024. Beginning on January 1, 2025, the temporary regulatory capital benefits will be fully reversed. Management believes, as of March 31, 2024, that Pinnacle Financial and Pinnacle Bank met all capital adequacy requirements to which they are subject. To be categorized as well-capitalized under applicable banking regulations, Pinnacle Bank must maintain certain total risk-based, Tier 1 risk-based, common equity Tier 1 and Tier 1 leverage ratios as set forth in the following table and not be subject to a written agreement, order or directive to maintain a higher capital level. The capital conservation buffer is not included in the required ratios of the table presented below.

Summary of Significant Accounting Policies (Policies)	3 Months Ended

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, 2023 (2023 10-K). These unaudited consolidated financial statements include the accounts of Pinnacle Financial and its wholly-owned subsidiaries. Certain statutory trust affiliates of Pinnacle Financial, as noted in Note 11. Other Borrowings, are included in these unaudited 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. Mortgage Servicing Rights — On March 31, 2024, Pinnacle Financial recognized a mortgage servicing asset totaling $11.8 million related to a commercial mortgage loan portfolio. Upon the sale of these commercial loans, the rights to service loans (MSRs) are capitalized and represent the fair value of future net servicing fees from servicing activities associated with these commercial mortgage loans. Pinnacle Financial has elected to account for this class of MSRs under the fair value measurement method. Under this method, capitalized MSRs will be recorded in other assets in the accompanying consolidated balance sheet with changes in the fair value of the MSRs for each period presented recorded in other noninterest income in the accompanying consolidated statement of income. MSRs are recorded at fair value utilizing a number of assumptions, including prepayment speeds, interest rates, discount rates and other economic factors. Changes in the underlying assumptions could materially affect the fair value of MSRs. The value of servicing rights is initially measured using a discounted cash flow model. All servicing rights capitalized have involved the retention of servicing rights only; Pinnacle Financial does not retain residual interest, "first loss" obligations, or other similar on-going financial interests in the loans it sells to third parties, nor has Pinnacle Financial participated in any securitizations with any special purpose entities with respect to these MSRs. Except for recovery of amounts invested in acquiring servicing rights, servicing mortgage loans for others does not generally impose significant financial risks to the servicer. There are, however, certain investors for whom servicing does involve some risk of loss. For example, servicing Federal Housing Administration insured or Veterans Administration guaranteed loans can result in the servicer advancing principal and interest payments for delinquent borrowers, or incurring a shortfall in the total amount of principal collected under certain foreclosure circumstances.
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 months ended March 31, 2024 and 2023 (in thousands, except per share data): Three months ended 2024 2023 Basic net income per common share calculation: Numerator - Net income available to common shareholders $ 120,146 $ 133,473 Denominator - Weighted average common shares outstanding 76,278 75,921 Basic net income per common share $ 1.58 $ 1.76 Diluted net income per common share calculation: Numerator - Net income available to common shareholders $ 120,146 $ 133,473 Denominator - Weighted average common shares outstanding 76,278 75,921 Dilutive common shares contingently issuable 151 121 Weighted average diluted common shares outstanding 76,429 76,042 Diluted net income per common share $ 1.57 $ 1.76
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 the London Interbank Offered Rate (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 substantially all of its LIBOR-based loans to its preferred replacement index, a Secured Overnight Financing Rate (SOFR) based index as of March 31, 2024. 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 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. Pinnacle Financial adopted ASU 2022-03 on January 1, 2024 and it did not have a material impact on Pinnacle Financial's accounting or 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. Pinnacle Financial adopted ASU 2023-02 on January 1, 2024 and it did not have a material impact on Pinnacle Financial's accounting or disclosures.
Newly Issued Not Yet Effective Accounting Standards	Newly Issued Not Yet Effective Accounting Standards — In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which amends the guidance for income tax disclosures to include certain required disclosures related to tax rate reconciliations, including certain categories of expense requiring disclosure, income taxes paid, including disclosure of taxes paid disaggregated by nation, state, and foreign taxes, and other disclosures for disaggregation of income before income tax expense (or benefit) and income tax expense (or benefit) by domestic and foreign allocation. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2024. Early adoption is permitted. An entity should apply ASU 2023-09 on a prospective basis once adopted with retrospective application permitted. Pinnacle Financial is assessing ASU 2023-09 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
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 March 31, 2024 through the date of the issued financial statements with no subsequent events being noted as of the date of this filing.

Share-Based Payment Arrangement [Abstract]
Summary of Activity for Unvested Restricted Share Awards	A summary of activity for unvested restricted share awards for the three months ended March 31, 2024 is as follows: Number Grant Date Unvested at December 31, 2023 703,399 $ 77.68 Shares awarded 199,791 Restrictions lapsed and shares released to associates/directors (164,428) Shares forfeited (10,095) Unvested at March 31, 2024 728,667 $ 80.26 Pinnacle Financial has granted restricted share awards to associates (including certain members of executive management) 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 three months ended March 31, 2024. 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 2024 Associates (2) 5 189,901 10 15 2,199 187,677 Outside Director Awards (3) 2024 Outside directors 1 9,890 — — — 9,890 (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.

(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, 2025 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 was terminated during the year-to-date period ended March 31, 2024. 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.

At March 31, 2024 and December 31, 2023, there were no interest rate swap agreements designated as non-hedge derivatives cleared through clearing houses. The effects of Pinnacle Financial's interest rate swaps to facilitate customers' transactions on the income statement during the three months ended March 31, 2024 and 2023 were as follows (in thousands): Amount of Loss Recognized in Income Location of Loss Recognized in Income Three Months Ended March 31, 2024 2023 Interest rate swap agreements Other noninterest income $ (178) $ (63)
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 March 31, 2024 and December 31, 2023 is as follows (in thousands): March 31, 2024 December 31, 2023 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 3.59 4.00%-4.50% minus USD-Term SOFR 1M N/A $ 875,000 $ 22,466 $ 875,000 $ 36,483 Interest rate collars - loans Other assets 3.59 4.25%-4.75% minus USD-Term SOFR 1M USD-Term SOFR 1M minus 6.75%-7.00% 875,000 23,463 875,000 38,314 $ 1,750,000 $ 45,929 $ 1,750,000 $ 74,797 The effects of Pinnacle Financial's cash flow hedge relationships on the statement of comprehensive income (loss) during the three months ended March 31, 2024 and 2023 were as follows, net of tax (in thousands): Amount of Gain (Loss) Recognized Three Months Ended March 31, Asset derivatives 2024 2023 Interest rate floors and collars - loans $ (19,646) $ 11,978 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, net of tax, were reclassified from accumulated other comprehensive income (loss) into net income during the three months ended March 31, 2024 and 2023, respectively. Approximately $6.5 million in unrealized gains, net of tax, are expected to be reclassified from accumulated other comprehensive income (loss) into net income over the next twelve months related to previously terminated cash flow hedges. Derivatives designated as fair value hedges For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. Pinnacle Financial utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable available-for-sale securities. The hedging strategy converts the fixed interest rates to variable interest rates based on 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. Pinnacle Financial also utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on FHLB advances with payments beginning on various dates throughout 2024 and the first quarter of 2025. A summary of Pinnacle Financial's fair value hedge relationships as of March 31, 2024 and December 31, 2023 is as follows (in thousands): March 31, 2024 December 31, 2023 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 10.70 2.81% Federal Funds/ SOFR $ 2,112,139 $ 68,520 $ 543,061 $ 42,983 Interest rate swaps - borrowings Other assets N/A N/A N/A — — 750,000 3,654 Liability derivatives Interest rate swaps - securities Other liabilities N/A N/A N/A $ — $ — $ 1,569,078 $ (1,275) Interest rate swaps - borrowings Other liabilities 3.48 5.33% SOFR 1,175,000 (23,963) 425,000 (1,656) $ 3,287,139 $ 44,557 $ 3,287,139 $ 43,706 (1) The variation margin payments for derivatives cleared through central clearing houses are characterized as settlements. At March 31, 2024 and December 31, 2023, the notional amount of fair value derivatives cleared through central clearing houses was $2.0 billion with a fair value that approximates zero due to $27.8 million and $4.0 million in variation margin payments. Notional amounts of $392.2 million as of March 31, 2024 receive a variable rate of interest based on the daily compounded federal funds rate and notional amounts totaling $2.9 billion as of March 31, 2024 receive a variable rate of interest based on the daily compounded SOFR. The effects of Pinnacle Financial's securities fair value hedge relationships on the income statement during the three months ended March 31, 2024 and 2023 were as follows (in thousands): Location of Gain (Loss) Amount of Gain (Loss) Recognized in Income Three Months Ended March 31, Securities 2024 2023 Interest rate swaps - securities Interest income on securities $ 26,812 $ (31,685) Securities available-for-sale Interest income on securities $ (26,812) $ 31,685 FHLB advances Interest rate swaps - FHLB advances Interest expense on FHLB advances and other borrowings $ (25,961) $ 1,883 FHLB advances Interest expense on FHLB advances and other borrowings $ 25,961 $ (1,883) The following amounts were recorded on the balance sheet related to cumulative basis adjustments for fair value hedges at March 31, 2024 and December 31, 2023 (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 March 31, 2024 December 31, 2023 March 31, 2024 December 31, 2023 Line item on the balance sheet Securities available-for-sale $ 2,044,651 $ 2,074,621 $ (68,520) $ (41,708) Federal Home Loan Bank advances $ 1,151,037 $ 1,173,002 $ (23,963) $ (1,998) During the three months ended March 31, 2024 and 2023, amortization expense totaling $104,000 and $210,000, respectively, related to previously terminated fair value hedges was recognized as a reduction to interest income on loans.

[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.

[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. The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant. These shares represent forfeitures resulting from recipients whose employment was terminated during the year-to-date period ended March 31, 2024. 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 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, 2025 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.

[1]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.[2] 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. These shares represent forfeitures resulting from recipients whose employment was terminated during the year-to-date period ended March 31, 2024. 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.
