SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by Enterprise Financial Services Corp (the “Company,” “EFSC,” or “Enterprise”) 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 months ended March 31, 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 additional disclosure requirements 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.
