Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The significant accounting policies used by Enterprise Financial Services Corp in the preparation of the condensed consolidated financial statements are summarized below: Business and Consolidation Enterprise is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers primarily located in Arizona, California, Kansas, Missouri, Nevada, and New Mexico through its banking subsidiary, Enterprise Bank & Trust. Operating results for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2022. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC. Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Except as disclosed herein, there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the statements of financial position, results of operations, and cash flow for the interim periods. Recent Accounting Pronouncements FASB ASU 2021-01, Reference Rate Reform (Topic 848): Scope (ASU 2021-01). ASU 2021-01 was issued in January 2021 and provided optional expedients and exceptions in ASC 848 to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment only applies to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments will not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in this update were effective immediately upon issuance and did not have a material effect on the consolidated financial statements. FASB ASU 2022-02, Financial Instruments–Credit Losses (Topic 326); Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 was issued in March 2022 and eliminates the accounting guidance on troubled debt restructurings for creditors in ASC 310-40 and amends the guidance on “vintage disclosures” to require disclosure of current-period gross write-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under ASC 326 and adds enhanced disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty. The amendments in this update will be effective for fiscal years beginning after December 15, 2022 for entities that have adopted the amendments in ASU 2016-13, Financial Instruments–Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments . The Company is evaluating the accounting and disclosure requirements of ASU 2022-02 and does not expect them to have a material effect on the consolidated financial statements. FASB ASU 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . ASU 2022-03 was issued in June 2022 to (1) to clarify the guidance in Topic 820, Fair Value Measurement , when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (2) to amend a related illustrative example, and (3) to introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Company is evaluating the accounting and disclosure requirements of ASU 2022-03 and does not expect them to have a material effect on the consolidated financial statements. Acquisitions and Divestitures Acquisitions and business combinations are accounted for using the acquisition method of accounting. The assets and liabilities of the acquired entities have been recorded at their estimated fair values at the date of acquisition. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. The purchase price allocation process requires an estimation of the fair values of the assets acquired and the liabilities assumed. When a business combination agreement provides for an adjustment to the cost of the combination contingent on future events, the Company includes an estimate of the acquisition-date fair value as part of the cost of the combination. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Fair values are considered preliminary until final fair values are determined, or the measurement period has passed, which is no later than one year from the date of acquisition. The results of operations of the acquired business are included in the Company’s consolidated financial statements from the date of acquisition. Merger-related expenses include costs directly related to merger or acquisition activity and include legal and professional fees, system consolidation and conversion costs, and compensation costs such as severance and retention incentives for employees impacted by acquisition activity. The Company accounts for merger-related expenses in the periods in which the costs are incurred and the services are received. For divestitures, the Company measures an asset (disposal group) classified as held-for-sale at the lower of its carrying value at the date the asset is initially classified as held-for-sale or its fair value less costs to sell. The Company reports the results of operations of an entity or group of components that either has been disposed of or held-for-sale as discontinued operations only if the disposal of that component represents a strategic shift that has or will have a major effect on an entity’s operations and financial results. Any incremental direct costs incurred to transact the sale are allocated against the gain or loss on the sale. These costs typically include items such as legal fees, title transfer fees, broker fees, etc. Any goodwill and intangible assets associated with the portion of the reporting unit to be disposed of is included in the carrying amount of the business in determining the gain or loss on the sale.

The Company believes the held-to-maturity category is consistent with the Company’s intent for these securities. The transfer of securities was made at fair value at the time of transfer. The unamortized portion of the unrealized holding gain at the time of transfer is retained in accumulated other comprehensive income and in the carrying value of held-to-maturity securities. The balance of held-to-maturity securities in the “Amortized Cost” column in the table above includes a cumulative net unamortized unrealized gain of $19.4 million and $21.0 million at June 30, 2022 and December 31, 2021, respectively. Such amounts are amortized over the remaining life of the securities. At June 30, 2022 and December 31, 2021, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than U.S. Government agencies and sponsored enterprises. The agency mortgage-backed securities are all issued by U.S. Government agencies and sponsored enterprises. Securities having a fair value of $680.1 million and $752.7 million at June 30, 2022 and December 31, 2021, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions. The amortized cost and estimated fair value of debt securities at June 30, 2022, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. The weighted average life of the mortgage-backed securities is approximately 5 years.

At each of June 30, 2022 and December 31, 2021, the Company had not recorded an ACL on available-for-sale securities. Accrued interest receivable on held-to-maturity debt securities totaled $4.4 million and $3.4 million at June 30, 2022 and December 31 2021, respectively, and is excluded from the estimate of expected credit losses. The estimate of expected credit losses considers historical credit loss information adjusted for current conditions and reasonable and supportable forecasts. The ACL on held-to-maturity securities was $0.7 million at June 30, 2022 and $0.6 million at December 31, 2021. There were no sales of available-for-sale investment securities during the three months ended June 30, 2022 or 2021. Other Investments At June 30, 2022 and December 31, 2021, other investments totaled $61.3 million and $59.9 million, respectively. As a member of the FHLB system administered by the Federal Housing Finance Agency, the Bank is required to maintain a minimum investment in capital stock with the FHLB consisting of membership stock and activity-based stock. The FHLB capital stock of $12.0 million and $12.1 million at June 30, 2022 and December 31, 2021, respectively, is recorded at cost, which represents redemption value, and is included in other investments in the consolidated balance sheets. The remaining amounts in other investments primarily include investments in SBICs, CDFIs, private equity investments, and the Company’s investment in unconsolidated trusts used to issue trust preferred securities to third parties.

The Company utilizes three forecasts in the model: Moody’s baseline, a stronger near-term growth upside and a moderate recession downside forecast. The Company weights these scenarios at 40%, 30%, and 30%, respectively, which added approximately $13.6 million to the ACL over the baseline model. These forecasts incorporate an expectation that government stimulus will decline, the Federal Reserve will wind down its treasury and mortgage-backed securities portfolio and continue raising the federal funds rate, that the pandemic will begin to slowly recede, that the Russia-Ukraine military conflict will have a limited disruption on the economy and the risk of a period of stagflation. The Company has also recognized the risk posed by loans that have received multiple deferrals of principal and interest payments, including the hospitality sector, by allocating additional reserves to those segments. Some of the key risks to the forecasts that could result in future provision for credit losses are additional shutdowns and self-quarantines from another significant wave of COVID-19, continued or worsening supply-chain disruptions, labor shortages and declines in job growth, or a tightening of financial market conditions. In addition to the CECL methodology, the Company incorporates qualitative adjustments into the ACL on loans to capture credit risks inherent within the loan portfolio that are not captured in the discounted cash flow (DCF) model. Included in these risks are 1) changes in lending policies and procedures, 2) actual and expected changes in business and economic conditions, 3) changes in the nature and volume of the portfolio, 4) changes in lending management, 5) changes in volume and the severity of past due loans, 6) changes in the quality of the loan review system, 7) changes in the value of underlying collateral, 8) the existence and effect of concentrations of credit and 9) other factors such as the regulatory, legal and competitive environments and events such as natural disasters and pandemics. At June 30, 2022, the ACL on loans included a qualitative adjustment of approximately $40.8 million. Of this amount, approximately $7.3 million was allocated to sponsor finance loans due to their unsecured nature.

This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: • Grades 1, 2, and 3 – Includes loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow, and whose management team has experience and depth within their industry. • Grade 4 – Includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow. • Grade 5 – Includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow. • Grade 6 – Includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may also include circumstances where the borrower is starting to reverse a negative trend or condition, or has recently been upgraded from a 7, 8, or 9 rating. • Grade 7 – Watch credits are borrowers that have experienced financial setback of a nature that is not determined to be severe or influence ‘ongoing concern’ expectations. Although possible, no loss is anticipated at this time, due to strong collateral and/or guarantor support. • Grade 8 – Substandard credits include those borrowers characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted. • Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off, or debt renegotiation with the borrower. The borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on nonaccrual.

Commitments and Contingencies Disclosure [Abstract]
Commitments	COMMITMENTS AND CONTINGENCIES The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. The contractual amounts of off-balance-sheet financial instruments are as follows: (in thousands) June 30, 2022 December 31, 2021 Commitments to extend credit $ 2,619,588 $ 2,481,173 Letters of credit 66,739 77,314 Off-Balance Sheet Credit Risk Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at June 30, 2022 and December 31, 2021, approximately $257.5 million and $238.7 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate. Other liabilities includes $8.1 million and $7.6 million for estimated losses attributable to the unadvanced commitments at June 30, 2022 and December 31, 2021, respectively. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance or payment of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. As of June 30, 2022, the approximate remaining terms of standby letters of credit range from 1 month to 11 years. Contingencies The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Management believes there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s borrowings. The Company does not enter into derivative financial instruments for trading purposes. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. These derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. The Company has executed a series of cash flow hedges to fix the effective interest rate for payments due on $62.0 million of LIBOR-based junior subordinated debentures to a weighted-average-fixed rate o f 2.62%. Select terms of the hedges are as follows: (in thousands) Notional Fixed Rate Maturity Date $ 15,465 2.60 % March 15, 2024 $ 14,433 2.60 % March 30, 2024 $ 18,558 2.64 % March 15, 2026 $ 13,506 2.64 % March 17, 2026 The gain or loss on derivatives designated and qualified as cash flow hedges of interest rate risk are recorded in accumulated other comprehensive income and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are paid on the Company’s variable-rate debt. During the next twelve months, the Company estimates an additional $0.3 million will be reclassified as a decrease to interest expense. Non-designated Hedges Derivatives not designated as hedges are not considered speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings as a component of other noninterest income. The table below presents the fair value of the Company’s derivative financial instruments: Notional Amount Derivative Assets Derivative Liabilities (in thousands) June 30, December 31, 2021 June 30, December 31, 2021 June 30, December 31, 2021 Derivatives Designated as Hedging Instruments: Interest rate swap $ 61,962 $ 61,962 $ 755 $ — $ — $ 2,911 Derivatives not Designated as Hedging Instruments: Interest rate swap $ 901,995 $ 918,698 $ 12,559 $ 12,869 $ 12,589 $ 12,883 Derivative assets are classified on the balance sheet in other assets.

Equity [Abstract]
SHAREHOLDERS’ EQUITY	SHAREHOLDERS’ EQUITY Share Repurchases/Retirement The Company periodically adopts share repurchase plans that authorize open market repurchases of common stock. Shares acquired through the repurchase plan are classified as treasury stock or the shares are immediately retired upon settlement, depending on plan authorization. When shares are retired, the excess of repurchase price over par is allocated between additional paid in capital and retained earnings.

Except as disclosed herein, there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated.

Recent Accounting Pronouncements	Recent Accounting Pronouncements FASB ASU 2021-01, Reference Rate Reform (Topic 848): Scope (ASU 2021-01). ASU 2021-01 was issued in January 2021 and provided optional expedients and exceptions in ASC 848 to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment only applies to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments will not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in this update were effective immediately upon issuance and did not have a material effect on the consolidated financial statements. FASB ASU 2022-02, Financial Instruments–Credit Losses (Topic 326); Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 was issued in March 2022 and eliminates the accounting guidance on troubled debt restructurings for creditors in ASC 310-40 and amends the guidance on “vintage disclosures” to require disclosure of current-period gross write-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under ASC 326 and adds enhanced disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty. The amendments in this update will be effective for fiscal years beginning after December 15, 2022 for entities that have adopted the amendments in ASU 2016-13, Financial Instruments–Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments . The Company is evaluating the accounting and disclosure requirements of ASU 2022-02 and does not expect them to have a material effect on the consolidated financial statements. FASB ASU 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . ASU 2022-03 was issued in June 2022 to (1) to clarify the guidance in Topic 820, Fair Value Measurement , when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (2) to amend a related illustrative example, and (3) to introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The Company is evaluating the accounting and disclosure requirements of ASU 2022-03 and does not expect them to have a material effect on the consolidated financial statements.
Acquisitions and Divestitures	Acquisitions and Divestitures Acquisitions and business combinations are accounted for using the acquisition method of accounting. The assets and liabilities of the acquired entities have been recorded at their estimated fair values at the date of acquisition. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. The purchase price allocation process requires an estimation of the fair values of the assets acquired and the liabilities assumed. When a business combination agreement provides for an adjustment to the cost of the combination contingent on future events, the Company includes an estimate of the acquisition-date fair value as part of the cost of the combination. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Fair values are considered preliminary until final fair values are determined, or the measurement period has passed, which is no later than one year from the date of acquisition. The results of operations of the acquired business are included in the Company’s consolidated financial statements from the date of acquisition. Merger-related expenses include costs directly related to merger or acquisition activity and include legal and professional fees, system consolidation and conversion costs, and compensation costs such as severance and retention incentives for employees impacted by acquisition activity. The Company accounts for merger-related expenses in the periods in which the costs are incurred and the services are received. For divestitures, the Company measures an asset (disposal group) classified as held-for-sale at the lower of its carrying value at the date the asset is initially classified as held-for-sale or its fair value less costs to sell. The Company reports the results of operations of an entity or group of components that either has been disposed of or held-for-sale as discontinued operations only if the disposal of that component represents a strategic shift that has or will have a major effect on an entity’s operations and financial results. Any incremental direct costs incurred to transact the sale are allocated against the gain or loss on the sale. These costs typically include items such as legal fees, title transfer fees, broker fees, etc. Any goodwill and intangible assets associated with the portion of the reporting unit to be disposed of is included in the carrying amount of the business in determining the gain or loss on the sale.
