ENTERPRISE FINANCIAL SERVICES CORP AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (Unaudited)

NOTE 1 - 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, Florida, Kansas, Missouri, Nevada, and New Mexico through its banking subsidiary, Enterprise Bank & Trust.

Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2023. 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, 2022, 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, 2022.

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

On January 1, 2023, the Company adopted 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 charge-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 adoption of this update did not have a material effect on the Company’s consolidated financial statements.

FASB ASU 2021-01, Reference Rate Reform (Topic 848): Scope (ASU 2021-01). ASU 2021-01 was issued in January 2021 and provides 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, where 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

6

statements. In December 2022, ASU 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset date of Topic 848 was issued, which extends the sunset date from December 31, 2022 to December 31, 2024.

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) 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) amend a related illustrative example, and (3) 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 has evaluated the accounting and disclosure requirements of ASU 2022-03 and does not expect them to have a material effect on the consolidated financial statements.

FASB ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 was issued in March 2023 to allow reporting entities to consistently account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. If certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits, instead of only low-income-housing tax credit (“LIHTC”) structures. This amendment also eliminates certain LIHTC-specific guidance aligning the accounting with other equity investments in tax credit structures. 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 2023-02 and does not expect them to have a material effect on the consolidated financial statements.

NOTE 2 - EARNINGS PER SHARE

Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method.

The following table presents a summary of per common share data and amounts for the periods indicated.

	Three months ended March 31,
(in thousands, except per share data)	2023		2022
Net income available to common shareholders	$	54,800	$	46,464
Weighted average common shares outstanding	37,305		37,788
Additional dilutive common stock equivalents	182		70
Weighted average diluted common shares outstanding	37,487		37,858
Basic earnings per common share:	$	1.47	$	1.23
Diluted earnings per common share:	1.46		1.23

For the three months ended March 31, 2023 and 2022, common stock equivalents of approximately 311,000 and 276,000, respectively, were excluded from the earnings per share calculations because their effect would have been anti-dilutive.

The balance of held-to-maturity securities in the “Amortized Cost” column in the table above includes a cumulative net unamortized unrealized gain of $16.8 million and $17.6 million at March 31, 2023 and December 31, 2022, respectively. Such amounts are amortized over the remaining life of the securities.

At March 31, 2023 and December 31, 2022, 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

8

agency mortgage-backed securities are all issued by U.S. Government agencies and sponsored enterprises. Securities having a fair value of $1.8 billion and $734.5 million at March 31, 2023 and December 31, 2022, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions, in addition to collateral securing borrowing bases with the FHLB and the Federal Reserve.

The amortized cost and estimated fair value of debt securities at March 31, 2023, 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 6 years.

The unrealized losses at both March 31, 2023 and December 31, 2022 were attributable primarily to changes in market interest rates after the securities were purchased. In March 2023, the Company established an allowance for credit losses on available-for-sale investment securities through a provision for credit losses of $4.8 million and subsequently charged-off $4.8 million. The charge-off related to the impairment of a debt security from a bank that

9

failed in 2023. At each of March 31, 2023 and December 31, 2022, the Company had no allowance recorded on available-for-sale securities.

Accrued interest receivable on held-to-maturity debt securities totaled $6.6 million and $5.8 million at March 31, 2023 and December 31, 2022, 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 $0.9 million at March 31, 2023 and $0.7 million at December 31, 2022.

The Company sold $28.4 million of available-for-sale securities in January 2023 for a gain of $0.4 million. There were no sales of available-for-sale investment securities during the three months ended March 31, 2022.

Other Investments

At March 31, 2023 and December 31, 2022, other investments totaled $62.9 million and $63.8 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 $14.0 million at both March 31, 2023 and December 31, 2022 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 CECL methodology incorporates various economic scenarios. 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 $14.2 million to the ACL over the baseline model at March 31, 2023. These forecasts incorporate an expectation that the Federal Reserve will continue quantitative tightening and raise the federal funds rate to 5.00% to 5.25% in 2023 and that the recent bank failures are not an indication of a broader problem in the industry. The Company has also recognized various risks posed by loans in certain segments, including the hospitality and commercial office sectors, 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 market reactions to the Federal Reserve policy actions that could push the economy into a recession, persistently higher inflation, tightening in the credit markets, and further weakness in the financial system.

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 March 31, 2023, the ACL on loans included a qualitative adjustment of approximately $43.2 million. Of this amount, approximately $13.8 million was allocated to sponsor finance loans due to their unsecured nature.

The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon origination or acquisition. 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. The Company 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. 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.

14

The most common concession the Company provides to borrowers experiencing financial difficulty is a term extension. In limited circumstances, the Company may modify loans by providing principal forgiveness or an interest rate reduction. When principal forgiveness is provided, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses.

In some cases, the Company will modify a loan by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as an interest rate reduction or principal forgiveness, may be granted.

The following table shows loans modified to borrowers experiencing financial difficulty, disaggregated by loan class and type of concession granted:

	Term Extension
(in thousands)	March 31, 2023		% of Total Class of Financing Receivable
Commercial and industrial	$	22,818	0.57	%
Real estate:
Construction and land development	1,201		0.18	%
Total	$	24,019

The term extensions were for 2-12 months, and all loans were current under the modified terms.

There were no loans restructured during the three months ended March 31, 2022, and no troubled debt restructurings subsequently defaulted during the three months ended March 31, 2022.

15

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, payment experience, credit documentation, current economic factors and other factors. 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 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 – Special Mention credits are borrowers that 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.

NOTE 5 - COMMITMENTS AND CONTINGENCIES

The Company issues financial instruments with off balance sheet risk in the normal course of business. 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)	March 31, 2023		December 31, 2022
Commitments to extend credit	$	3,053,927	$	3,113,966
Letters of credit	94,361		68,544

19

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 March 31, 2023 and December 31, 2022, approximately $249.7 million and $246.5 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 $10.2 million and $12.1 million for estimated losses attributable to the unadvanced commitments at March 31, 2023 and December 31, 2022, 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 March 31, 2023, the approximate remaining terms of standby letters of credit range from 1 month to 10 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.

NOTE 6 - 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.

For hedges of the Company’s variable-rate loans, interest rate swaps designated as cash flow hedges involve the receipt of fixed amounts and the Company making variable rate payments. In the fourth quarter 2022, the Company executed a cash flow hedge to reduce a portion of variability in cash flows on the Company’s prime based loan portfolio. The interest rate swap has a notional value of $100.0 million, that effectively fixes the interest rate at 6.63% for the notional amount and has a maturity date of January 1, 2028. In January 2023, the Company entered

20

into another hedge on the prime based loan portfolio with a notional value of $50.0 million, that effectively fixes the interest rate at 6.56% for the notional amount and has a maturity date of February 1, 2027.

In addition, the Company executed a prime based interest rate collar in the fourth quarter 2022 with a notional amount of $100.0 million. The collar includes a cap of 8.14% and a floor of 5.25%. This transaction, commonly referred to as a zero cost collar, involves the Company selling an interest rate cap where payments will be made when the index exceeds the cap rate, and the purchase of a floor where payments will be received if the index falls below the floor. The collar matures on October 1, 2029.

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 of 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 income or 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 income or expense as interest payments are paid on the Company’s variable-rate loans and debt. During the next twelve months, the Company estimates an additional $1.8 million will be reclassified as a decrease to interest income and $1.3 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.

Forward Looking Statements

This Quarterly Report on Form 10-Q contains information and statements that are considered “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements are based on management’s current expectations and beliefs concerning future developments and their potential effects on the Company, and include, without limitation, statements about the Company’s plans, strategies, goals, objectives, expectations, or consequences of statements about the future performance, operations, products and services of the Company and its subsidiaries, as well as statements about the Company’s expectations regarding revenue and asset growth, financial performance and profitability, loan and deposit growth, yields and returns, loan diversification and credit management, products and services, shareholder value creation and the impact of acquisitions. Forward-looking statements are typically identified with the use of terms such as “may,” “might,” “will,” “would,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “could,” “continue,” “intend,” and the negative and other variations of these terms and similar words and expressions, although some forward-looking statements may be expressed differently. Forward-looking statements are inherently subject to risks and uncertainties and our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. You should be aware that our actual results could differ materially from those contained in the forward-looking statements.

While there is no assurance that any list of risks and uncertainties or risk factors is complete, important factors that could cause actual results to differ materially from those in the forward-looking statements include the following, without limitation: our ability to efficiently integrate acquisitions into our operations, retain the customers of these businesses and grow the acquired operations; credit risk; changes in the appraised valuation of real estate securing impaired loans; our ability to recover our investment in loans; fluctuations in the fair value of collateral underlying loans; outcomes of litigation and other contingencies; exposure to general and local economic and market conditions, including risk of recession, high unemployment rates, higher inflation and its impacts (including U.S. federal government measures to address higher inflation), U.S. fiscal debt, budget and tax matters, and any slowdown in global economic growth; risks associated with rapid increases or decreases in prevailing interest rates; changes in business prospects that could impact goodwill estimates and assumptions; consolidation within the banking industry; competition from banks and other financial institutions; the ability to attract and retain relationship officers and other key personnel; burdens imposed by federal and state regulation; changes in legislative or regulatory requirements, as well as current, pending or future legislation or regulation that could have a negative effect on our revenue and businesses, including rules and regulations relating to bank products and financial services; changes in accounting policies and practices or accounting standards; changes in the method of determining LIBOR and the phase-out of LIBOR; natural disasters; terrorist activities, war and geopolitical matters (including the war in Ukraine and the imposition of additional sanctions and export controls in connection therewith), or pandemics, including the COVID-19 pandemic, and their effects on economic and business environments in which we operate, including the ongoing disruption to the financial market and other economic activity caused by the COVID-19 pandemic; and other risks discussed under the caption “Risk Factors” under Part I, Item 1A of our 2022 Annual Report on Form 10-K, and other reports filed with the SEC, all of which could cause the Company’s actual results to differ from those set forth in the forward-looking statements. The Company cautions that the preceding list is not exhaustive of all possible risk factors and other factors could also adversely affect the Company’s results.

Readers are cautioned not to place undue reliance on our forward-looking statements, which reflect management’s analysis and expectations only as of the date of such statements. Forward-looking statements speak only as of the date they are made, and the Company does not intend, and undertakes no obligation, to publicly revise or update forward-looking statements after the date of this report, whether as a result of new information, future events or otherwise, except as required by federal securities law. You should understand that it is not possible to predict or identify all risk factors. Readers should carefully review all disclosures we file from time to time with the SEC which are available on our website at www.enterprisebank.com under “Investor Relations.”

Introduction

The following discussion describes the significant changes to the financial condition of the Company that have occurred during the first three months of 2023 compared to the financial condition as of December 31, 2022. In addition, this discussion summarizes the significant factors affecting the results of operations of the Company for the three months ended March 31, 2023, compared to the linked fourth quarter (“linked quarter”) in 2022 and the results of operations, liquidity and cash flows for the three months ended March 31, 2023 compared to the same period in 2022 (“prior year quarter”). In light of the nature of the Company’s business, which is not seasonal, the Company’s management believes that the comparison to the linked quarter is the most relevant to understand the financial results from management’s perspective. For purposes of the Quarterly Report on Form 10-Q, the Company is presenting a comparison to the corresponding year-to-date period in 2022. This discussion should be read in conjunction with the accompanying condensed consolidated financial statements included in this report and our Annual Report on Form 10-K for the year ended December 31, 2022.

Critical Accounting Policies and Estimates

The Company’s critical accounting policies are considered important to the understanding of the Company’s financial condition and results of operations. These accounting policies require management’s most difficult, subjective and complex judgments about matters that are inherently uncertain. Because these estimates and judgments are based on current circumstances, they may change over time or prove to be inaccurate based on actual experience. If different assumptions or conditions were to prevail, and depending upon the severity of such changes, the possibility of a materially different financial condition and/or results of operations could reasonably be expected.

A full description of our critical accounting policies and the impact and any associated risks related to those policies on our business operations are discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” where such policies affect our reported and expected financial results. For a detailed discussion on the application of these and other accounting policies, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

The Company has prepared the consolidated financial information in this report in accordance with GAAP. The Company makes estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Such estimates include the valuation of loans, goodwill, intangible assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using loss experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statement in future periods. There can be no assurances that actual results will not differ from those estimates.

28

Allowance for Credit Losses

Utilizing the CECL methodology, the Company maintains separate allowances for funded loans, unfunded loans, and held-to-maturity securities, collectively the ACL. The ACL is a valuation account to adjust the cost basis to the amount expected to be collected, based on management’s estimate of experience, current conditions, and reasonable and supportable forecasts. For purposes of determining the allowance for funded and unfunded loans, the portfolios are segregated into pools that share similar risk characteristics and are then further segregated by credit grades. Loans that do not share similar risk characteristics are evaluated on an individual basis and are not included in the collective evaluation. The Company estimates the amount of the allowance based on loan loss experience, adjusted for current and forecasted economic conditions, including unemployment, changes in GDP, and commercial and residential real estate prices. The Company’s forecast of economic conditions uses internal and external information and considers a weighted average of a baseline, upside, and downside scenarios. Because economic conditions can change and are difficult to predict, the anticipated amount of estimated loan defaults and losses, and therefore the adequacy of the allowance, could change significantly and have a direct impact on the Company’s credit costs. The Company’s allowance for credit losses on loans was $138.3 million at March 31, 2023 based on the weighting of the different economic scenarios. As a hypothetical example, if the Company had only used the upside scenario, the allowance would have decreased $24.2 million. Conversely, the allowance would have increased $43.2 million using only the downside scenario.

Financial results and other notable items include:

•PPNR1 of $75.0 million in the first quarter 2023 decreased $3.6 million from the linked quarter PPNR of $78.6 million and increased $18.0 million from $57.0 million in the prior year period. The decrease from the linked quarter was primarily due to a seasonal increase in noninterest expense, partially offset by an increase in net interest income. The increase compared to the prior year quarter was primarily due to an increase in net interest income, partially offset by an increase in noninterest expense.

1 PPNR is a non-GAAP measure. Refer to discussion and reconciliation of these measures in the accompanying financial tables.

•Net interest income of $139.5 million for the first quarter 2023 increased $0.7 million and $38.4 million from the linked and prior year quarters, respectively. The NIM was 4.71% for the first quarter 2023, compared to 4.66% and 3.28% for the linked and prior year quarters, respectively. Net interest income and NIM benefited from higher average loan and investment balances and expanding yields on earning assets, partially offset by higher deposit costs and a decline in average interest-earning cash.

•Noninterest income of $16.9 million for the first quarter 2023 was stable compared to the linked quarter and decreased $1.7 million from the prior year quarter. The decline from the prior year quarter was primarily due to a decrease in customer swap fee income, card services revenue and tax credit income. Lower transaction volumes led to the decrease in customer swap fee income and tax credit income, and the Durbin Amendment cap on debit card income has limited card services revenue since July 1, 2022.

Balance sheet highlights:

•Loans – Total loans increased $274.8 million, or 11.4%, to $10.0 billion at March 31, 2023, compared to $9.7 billion at December 31, 2022. Average loans totaled $9.8 billion for the quarter ended March 31, 2023 compared to $9.4 billion in the fourth quarter 2022.

•Deposits – Total deposits increased $325.5 million, to $11.2 billion at March 31, 2023 from $10.8 billion at December 31, 2022. Total estimated insured deposits, which includes collateralized deposits, reciprocal deposits and accounts that qualify for pass through insurance, totaled $7.7 billion at March 31, 2023, compared to $4.9 billion at December 31,2022. Average deposits totaled $10.9 billion for the quarter ended March 31, 2023, compared to $11.0 billion for the fourth quarter 2022. Noninterest deposit accounts represented 37.6% of total deposits and the loan to deposit ratio was 89.8% at March 31, 2023.

•Asset quality – The allowance for credit losses on loans to total loans was 1.38% at March 31, 2023, compared to 1.41% at December 31, 2022. Nonperforming assets to total assets was 0.09% at March 31, 2023 compared to 0.08% at December 31, 2022. A provision for credit losses of $4.2 million was recorded in the first quarter of 2023, compared to $2.1 million in the linked quarter and a provision benefit of $4.1 million in the comparable prior year period. The provision for credit losses of $4.2 million recorded in the first quarter 2023 was primarily related to the credit impairment of an investment security in subordinated debt of a failed bank and loan growth, partially offset by a decrease in the reserve for unfunded commitments.

•Shareholders’ equity – Total shareholders’ equity was $1.59 billion at March 31, 2023, compared to $1.52 billion at December 31, 2022, and the tangible common equity to tangible assets ratio2 was 8.8% at March 31, 2023 compared to 8.4% at December 31, 2022. The Company and the Bank’s regulatory capital ratios exceeded the “well-capitalized” level at March 31, 2023.

The Company’s Board of Directors approved a quarterly dividend of $0.25 per common share, payable on June 30, 2023 to shareholders of record as of June 15, 2023. The Board of Directors also declared a cash dividend of $12.50 per share of Series A Preferred Stock (or $0.3125 per depositary share) representing a

31

5% per annum rate for the period commencing (and including) March 15, 2023 to (but excluding) June 15, 2023. The dividend will be payable on June 15, 2023 to shareholders of record on May 31, 2023.

The increase from the linked and prior year quarters reflects the benefit of higher market interest rates on the Company’s asset sensitive balance sheet combined with organic growth. The effective federal funds rate for the first quarter 2023 was 4.52%, an increase of 87 basis points, compared to the linked quarter, and a 440 basis point increase over the prior year quarter.

Compared to the linked quarter, interest income increased $12.4 million due to higher interest earned on a larger loan base resulting in a $13.3 million sequential expansion. This increase was partially offset by a $1.9 million decrease in interest on cash balances. Interest on loans benefited from a 46 basis point increase in yield and a $371.1 million increase in average loans compared to the linked quarter. The average interest rate of new loan originations in the first quarter 2023 was 6.53%. The yield on interest-earning cash deposits increased 121 basis points in the quarter but was offset by a $260.8 million decrease in the average balance which reduced interest income in the first quarter 2023.

Compared to the prior year quarter, the increase in interest income of $63.0 million was also primarily due to higher interest earned on a larger loan base, partially offset by a decline in interest earned on cash balances. The prior year quarter included $2.9 million of interest and fee income on loans from the Paycheck Protection Program that was mostly wound down in the fourth quarter 2022.

34

Compared to the linked quarter, interest expense increased $11.6 million primarily due to a $9.9 million increase in deposit interest expense and a $1.2 million increase in interest expense on FHLB borrowings. The increase in interest expense reflects a shift in the deposit mix from demand deposits and interest-bearing demand deposits to money market accounts and certificates of deposit, as well as higher rates paid on deposits and an increased use of FHLB borrowings. This deposit shift principally occurred during March following turmoil in the banking markets. The interest-bearing liability rate was 1.72% an increase of 65 basis points compared to the linked quarter. The average cost of interest-bearing deposits was 1.56%, an increase of 62 basis points over the linked quarter. The increase was primarily due to higher rates paid on commercial money market accounts, which increased 82 basis points to 2.22% in the current quarter.

Compared to the prior year quarter, interest expense increased $24.1 million primarily due to an increase in the cost of interest bearing liabilities. The cost of interest bearing deposits increased 139 basis points year-over-year, while the cost of total interest bearing liabilities increased 142 basis points during the same period.

The total cost of deposits, including noninterest-bearing demand accounts, was 0.92% during the first quarter 2023, compared to 0.53% and 0.10% in the linked and prior year quarters, respectively.

NIM, on a tax equivalent basis, was 4.71% in the first quarter 2023, an increase of five basis points from the linked quarter and an increase of 143 basis points from the prior year quarter. Since the first quarter 2022, NIM has expanded four consecutive quarters.

Total noninterest income for the first quarter 2023 was $16.9 million, stable with the linked quarter and a decrease of $1.7 million from the prior year quarter. Noninterest income in the first quarter 2023 included an increase in other income and wealth management revenue that was offsets by a decrease in deposit service charges and tax credit income. Other income increased primarily due to a gain on the sale of SBA loans and a gain on the sale of investment securities. In the first quarter 2023, SBA loans totaling $8.8 million were sold and $28.4 million of lower-yielding investment securities were sold in January 2023 at a gain and the proceeds were reinvested at a higher yield. Other income in the current and linked quarters also included $2.3 million and $3.2 million, respectively, of income from community development investments and private equity income. Income from these investments will vary among periods. Deposit service charges declined in the first quarter 2023 as the earnings credit rate used by customers to offset treasury management fees increased. Tax credit income is typically highest in the fourth quarter when transaction volumes peak.

The decrease from the prior year quarter was primarily due to decreases in tax credit income and card services revenue. Lower transaction volumes led to the decrease in tax credit income while the Durbin Amendment cap on

35

debit card income has limited card services revenue since July 1, 2022. Other income in the prior year quarter included $1.2 million of swap fee income, compared to $0.3 million in the first quarter 2023. Swap fee income is generated from customer hedging activities and was higher in the prior year quarter when market rates started to increase.

Noninterest expense was $81.0 million for the first quarter 2023, an increase of $3.8 million from $77.1 million in the linked quarter. Employee compensation and benefits increased $4.3 million from the linked quarter primarily due to a $3.4 million increase in employer payroll taxes and 401(k) matches that are seasonally higher in the first quarter each year, and a $3.3 million increase in salaries due to annual merit increases that became effective on March 1, 2023 and an increase in the associate base. These increases were partially offset by a $3.8 million decline in variable compensation that is typically higher in the fourth quarter each year. Deposit costs declined slightly from the linked quarter primarily due to higher year-end settlements that occurred in the linked quarter. Deposit costs relate to certain specialized deposit businesses that are impacted by higher interest rates as well as increasing average balances.

The increase in noninterest expense of $18.2 million from the prior year quarter was primarily an increase in the

associate base, merit increases throughout 2022 and 2023, and an increase in variable deposit costs.

Income Taxes

The Company’s effective tax rate was 21.8% for the first quarter 2023, relatively stable with the linked and prior year quarters effective tax rates of 21.5% and 21.9%. respectively.

Total assets were $13.3 billion at March 31, 2023, an increase of $271.8 million from December 31, 2022. Cash and cash equivalents were relatively stable, while loan production increased the loan portfolio and an improvement in the unrealized loss on available for sale investments increased the value of the securities portfolio. Total liabilities of $11.7 billion, increased $201.3 million from December 31, 2022. A $325.5 million increase in deposits, partially offset by a $107.8 million decrease in securities sold under agreements to repurchase, was the primary driver of the increase in total liabilities.

Investments

At March 31, 2023, investment securities were $2.3 billion, or 17%, of total assets, which is comparable to the Company’s historical percentage dating back to 2019. At December 31, 2022, investment securities were $2.2 billion, or 17%, of total assets.

The table below sets forth the carrying value of investment securities, excluding the allowance for credit losses:

Held-to-maturity securities	(65,013)		(82,133)
Total	$	(226,585)	$	(275,380)

Investment securities increased $30.1 million from the linked quarter, primarily due to a $31.7 million decrease in the unrealized loss on available-for-sale securities. Investment purchases in the quarter had a weighted average, tax equivalent yield of 4.79%. In January 2023, $28.4 million of available-for-sale investment securities with a tax equivalent yield of 4.0% were sold at a net gain of $0.4 million and were reinvested in securities with a 4.5% yield.

The average duration of the investment portfolio was 5.5 years at March 31, 2023. Due to the shorter duration of the loan portfolio of approximately 3 years, the Company leverages the investment portfolio to lengthen the overall

37

duration of the balance sheet, primarily using high-quality municipal securities. The expected cash flow from pay downs, maturities and interest over the next 12 months is approximately $262 million.

Loans by Type

The Company has a diversified loan portfolio, with no particular concentration of credit in any one economic sector; however, a substantial portion of the portfolio, including the C&I category, is secured by real estate. The ability of the Company’s borrowers to honor their contractual obligations is partially dependent upon the local economy and its effect on the real estate market.

The following table sets forth the composition of the loan portfolio by type of loans

(in thousands)	March 31, 2023		December 31, 2022		Increase (decrease)

*Specialty loan category

Loans totaled $10.0 billion at March 31, 2023 compared to $9.7 billion at December 31, 2022. The increase was driven primarily by C&I, CRE investor owned, construction and specialty loans. The increase in specialty loans was primarily in the sponsor finance and life insurance areas and each of the Company’s geographic regions increased loans during the quarter. Average line draw utilization was 42.4% for the first quarter of 2023, compared to 41.8% for the full year of 2022.

Specialty lending products, including sponsor finance, life insurance premium financing, and tax credits, consist primarily of C&I loans. These loans are sourced through relationships developed with estate planning firms and private equity funds and are not bound geographically by our markets. These specialized loan products offer opportunities to expand and diversify geographically by entering new markets. The Company continues to focus on originating high-quality C&I relationships, as they typically have variable interest rates and allow for cross selling opportunities involving other banking products. Life insurance premium financing and tax credits are typically lower risk products due to the high collateral value securing the loans.

38

SBA loans are also generated on a national basis, and primarily consist of loans collateralized by first lien, owner-occupied real estate properties. These loans predominantly have a 75% guarantee from the SBA. The Company may sell the guaranteed portion of the loan and retain servicing rights, and in the first quarter 2023, SBA loans totaling $8.8 million were sold.

Provision and Allowance for Credit Losses

The following table presents the components of the provision for credit losses:

	Quarter ended
(in thousands)	March 31, 2023		December 31, 2022		March 31, 2022
Provision (benefit) for credit losses on loans	$	1,099	$	(1,565)	$	(4,308)
Provision for available-for-sale securities	4,826		—		—
Provision (benefit) for off-balance sheet commitments	(1,914)		3,609		725
Provision (benefit) for held-to-maturity securities	137		46		(56)
Charge-offs (recoveries) of accrued interest	35		33		(429)
Provision (benefit) for credit losses	$	4,183	$	2,123	$	(4,068)

The provision for credit losses, which includes a provision for losses on unfunded commitments, is a charge to earnings to maintain the ACL at a level consistent with management’s assessment of expected losses in the loan portfolio at the balance sheet date. A provision for credit losses on both available-for-sale and held-to-maturity investment securities is recognized in certain circumstances. The Company also records reversals of interest on nonaccrual loans and interest recoveries directly through the provision of credit losses.

A provision for credit losses of $4.2 million was recognized for the first quarter 2023, compared to $2.1 million in the linked quarter and a provision benefit of $4.1 million in the prior year quarter. The provision in the first quarter 2023 was primarily related to the impairment of an available-for-sale investment security and loan growth, partially offset by a decrease in the reserve on unfunded commitments. The provision for credit losses on the available-for-sale investment security was related to a subordinated debt security in a publicly-traded bank that failed in the first quarter of 2023.

The following table summarizes the allocation of the ACL on loans:

	March 31, 2023				December 31, 2022
(in thousands)	Allowance		Percent of loans in each category to total loans		Allowance		Percent of loans in each category to total loans
Commercial and industrial	$	59,149	40.3	%	$	53,835	39.6	%

Total	$138,295		100.0	%	$136,932		100.0	%

The ACL on loans was 1.38% of loans at March 31, 2023, compared to 1.41% of loans at December 31, 2022. Loan growth, changes in economic metrics, and a continued positive trend in asset quality. Excluding guaranteed loans, the ACL to total loans was 1.53% at March 31, 2023, compared to 1.56% at December 31, 2022.

To the extent the Company does not recognize charge-offs and economic forecasts improve in future periods, the Company could recognize provision reversals. Conversely, if economic conditions and the Company’s forecast worsens and charge-offs increase, the Company could recognize elevated levels of provision for credit losses. The provision is also reflective of charge-offs (recoveries) in the period.

Total deposits excluding brokered certificates of deposits, were $10.8 billion at March 31, 2023, an increase of $74.9 million from December 31, 2022. The mix of the deposit portfolio shifted from noninterest-bearing demand deposits to higher yielding categories in the current quarter due to the competitive rate environment. Brokered certificates of deposit increased $250.5 million, to $369.5 million at March 31, 2023. Brokered certificates of deposit were used for term liquidity purposes in place of FHLB borrowings in the first quarter 2023. The Company has a specialty deposit portfolio focusing on property management, community associations, and escrow industries, in addition to deposits related to its specialty lending products. These deposits totaled $2.8 billion at March 31, 2023 and $2.5 billion at December 31, 2022.

To provide customers a deposit product with enhanced FDIC insurance, the Company participates in several programs through third parties that provide full FDIC insurance on deposit amounts by exchanging or reciprocating larger depository relationships with other member banks. Total reciprocal deposits were $486.7 million at March 31, 2023, compared to $205.8 million at December 31, 2022. The Company considers reciprocal accounts as customer-related deposits due to the customer relationship that generated the transaction.

At March 31, 2023, estimated uninsured deposits totaled $3.4 billion, compared to $5.9 billion at December 31, 2022. The decrease in estimated uninsured deposits was the result of an increase in reciprocal deposits and accounts that qualify for pass-through insurance.

As rates increase, deposit balances may decline or the composition of the deposit portfolio may continue to shift to higher-yielding deposit products, such as money market accounts or certificates of deposit. The total cost of deposits was 0.92% for the current quarter, compared to 0.53% for the linked quarter.

Shareholders’ Equity

Shareholders’ equity totaled $1.6 billion at March 31, 2023, an increase of $70.6 million from December 31, 2022. Significant activity during the first three months of 2023 was as follows:

•increase from net income of $55.7 million,

•net increase in fair value of securities and cash flow hedges of $24.4 million, and

•decrease from dividends paid on common and preferred stock of $10.3 million.

Liquidity and Capital Resources

Liquidity

The objective of liquidity management is to ensure we have the ability to generate sufficient cash or cash equivalents in a timely and cost-effective manner to meet our commitments as they become due. Typical demands on liquidity are changes in deposit levels, maturing time deposits which are not renewed, and fundings under credit commitments to customers. Funds are available from a number of sources, such as the core deposit base and loan and security repayments and maturities.

Additionally, liquidity is provided from lines of credit with the FHLB, the Federal Reserve, and correspondent banks; the ability to acquire large and brokered deposits, sales of the securities portfolio, and the ability to sell loans or loan participations to other banks. These alternatives are an important part of our liquidity plan and provide flexibility and efficient execution of the asset-liability management strategy.

The Company’s Asset-Liability Management Committee oversees our liquidity position, the parameters of which are approved by the Bank’s Board of Directors. Our liquidity position is monitored daily. Our liquidity management framework includes measurement of several key elements, such as the loan to deposit ratio, a liquidity ratio, and a dependency ratio. The Company’s liquidity framework also incorporates contingency planning to assess the nature and volatility of funding sources and to determine alternatives to these sources. While core deposits and loan and

42

investment repayments are principal sources of liquidity, funding diversification is another key element of liquidity management and is achieved by strategically varying depositor types, terms, funding markets, and instruments.

Liquidity from assets is available primarily from cash balances and the investment portfolio. Cash and interest-bearing deposits with other banks totaled $285.1 million at March 31, 2023 and $291.4 million at December 31, 2022. Recent increases in short term interest rates, a tightening of monetary policy by the Federal Reserve and recent bank failures has led to competitive pricing pressures and a reduction of deposits in the industry. To enhance liquidity, the Company reduced its reinvestment of investment portfolio cash flows during the three months ended March 31, 2023 compared to prior quarters. However, investment securities are an important tool to the Company’s

liquidity objectives.

Available on- and off-balance sheet liquidity sources include the following items:

(in thousands)	March 31, 2023
Federal Reserve Bank borrowing capacity	$	2,668,163
FHLB borrowing capacity	824,053
Unpledged securities	449,440
Federal funds lines (7 correspondent banks)	140,000
Cash and interest-bearing deposits	285,083
Holding Company line of credit	25,000
Total	$	4,391,739

The Company also has a portfolio of SBA guaranteed loans, a portion of which could be sold in the secondary market to generate earnings and liquidity.

In the normal course of business, the Company enters into certain forms of off-balance sheet transactions, including unfunded loan commitments and letters of credit. These transactions are managed through the Company’s various risk management processes. Management considers both on-balance sheet and off-balance sheet transactions in its evaluation of the Company’s liquidity. The Company has $3.1 billion in unused commitments to extend credit as of March 31, 2023. However, the nature of these commitments is such that the likelihood of funding them in the aggregate at any one time is low.

At the holding company level, the primary funding sources are dividends and payments from the Bank and proceeds from the issuance of equity (i.e. stock option exercises, stock offerings) and debt instruments. The main use of this liquidity is to provide the funds necessary to pay dividends to shareholders, service debt, invest in subsidiaries as necessary, and satisfy other operating requirements. The holding company maintains a revolving line of credit for an aggregate amount up to $25 million, all of which was available at March 31, 2023. The line of credit has a one-year term and was renewed in February 2023 for an additional one-year term. The proceeds can be used for general corporate purposes.

The Company has an effective automatic shelf registration statement on Form S-3 allowing for the issuance of various forms of equity and debt securities. The Company’s ability to offer securities pursuant to the registration statement depends on market conditions and the Company’s continuing eligibility to use the Form S-3 under rules of the SEC.

Strong capital ratios, credit quality and core earnings are essential to retaining cost-effective access to the wholesale funding markets. Deterioration in any of these factors could have a negative impact on the Company’s ability to access these funding sources and, as a result, these factors are monitored on an ongoing basis as part of the liquidity management process. The Bank is subject to regulations and, among other things, may be limited in its ability to pay dividends or transfer funds to the parent company. Accordingly, consolidated cash flows as presented in the consolidated statements of cash flows may not represent cash immediately available for the payment of cash dividends to the Company’s shareholders or for other cash needs.

43

Through the normal course of operations, the Company has entered into certain contractual obligations and other commitments. Such obligations relate to funding operations through deposits or debt issuances, as well as leases for premises and equipment. As a financial services provider, the Company routinely enters into commitments to extend credit. While contractual obligations represent future cash requirements of the Company, a significant portion of commitments to extend credit may expire without being drawn upon. Such commitments are subject to the same credit policies and approval process accorded to loans made by the Company. The Company also enters into derivative contracts under which the Company either receives cash from or pays cash to counterparties depending on changes in interest rates. Derivative contracts are carried at fair value on the consolidated balance sheet with the fair value representing the net present value of expected future cash receipts or payments based on market interest rates as of the balance sheet date. The fair value of these contracts changes daily as market interest rates change.

Capital Resources

The Company and the Bank are subject to various regulatory capital requirements administered by Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible 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, the Company and its bank affiliate must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The banking affiliate’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 the Company and the Bank to maintain minimum amounts and ratios (set forth in the following table) of total, Tier 1, and common equity tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. To be categorized as “well capitalized”, banks must maintain minimum total risk-based (10%), Tier 1 risk-based (8%), common equity tier 1 risk-based (6.5%), and Tier 1 leverage ratios (5%). In addition, the Company must maintain an additional CCB above the regulatory minimum ratio requirements. The CCB is designed to insulate banks from periods of stress and impose constraints on dividends, share repurchases and discretionary bonus payments when capital levels fall below prescribed levels. As of March 31, 2023, and December 31, 2022, the Company and the Bank met all capital adequacy requirements to which they are subject and exceeded the amounts required to be “well capitalized”.

The following table summarizes the Company’s various capital ratios:

	March 31, 2023				December 31, 2022
(in thousands)	EFSC		Bank		EFSC		Bank		To Be Well-Capitalized		Minimum Ratio with CCB
Common Equity Tier 1 Capital to Risk Weighted Assets	11.2	%	12.0	%	11.1	%	12.1	%	6.5	%	7.0	%
Tier 1 Capital to Risk Weighted Assets	12.6	%	12.0	%	12.6	%	12.1	%	8.0	%	8.5	%
Total Capital to Risk Weighted Assets	14.3	%	13.1	%	14.2	%	13.1	%	10.0	%	10.5	%

1 Not a required regulatory capital ratio.

The Company believes the tangible common equity ratio is an important measure of capital strength, even though it is considered a non-GAAP measure. A reconciliation has been included in this section under the caption “Use of Non-GAAP Financial Measures.”

44

Use of Non-GAAP Financial Measures:

The Company’s accounting and reporting policies conform to generally accepted accounting principles in the United States (“GAAP”) and the prevailing practices in the banking industry. However, the Company provides other financial measures, such as tangible common equity, PPNR, core efficiency ratio, and the tangible common equity ratio, in this report that are considered “non-GAAP financial measures.” Generally, a non-GAAP financial measure is a numerical measure of a company’s financial performance, financial position, or cash flows that exclude (or include) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP.

The Company considers its tangible common equity, PPNR, core efficiency ratio, and the tangible common equity ratio, collectively “core performance measures,” presented in this report and the included tables as important measures of financial performance, even though they are non-GAAP measures, as they provide supplemental information by which to evaluate the impact of certain non-comparable items, and the Company’s operating performance on an ongoing basis. Core performance measures exclude certain other income and expense items, such as merger-related expenses, facilities charges, and the gain or loss on sale of investment securities, that the Company believes to be not indicative of or useful to measure the Company’s operating performance on an ongoing basis. The attached tables contain a reconciliation of these core performance measures to the GAAP measures. The Company believes that the tangible common equity ratio provides useful information to investors about the Company’s capital strength even though it is considered to be a non-GAAP financial measure and is not part of the regulatory capital requirements to which the Company is subject.

The Company believes these non-GAAP measures and ratios, when taken together with the corresponding GAAP measures and ratios, provide meaningful supplemental information regarding the Company’s performance and capital strength. The Company’s management uses, and believes that investors benefit from referring to, these non-GAAP measures and ratios in assessing the Company’s operating results and related trends and when forecasting future periods. However, these non-GAAP measures and ratios should be considered in addition to, and not as a substitute for or preferable to, ratios prepared in accordance with GAAP. In the attached tables, the Company has provided a reconciliation of, where applicable, the most comparable GAAP financial measures and ratios to the non-GAAP financial measures and ratios, or a reconciliation of the non-GAAP calculation of the financial measures for the periods indicated.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The disclosures set forth in this item are qualified by the cautionary language regarding forward-looking statements in the introduction to Item 2 of Part I of this Quarterly Report on Form 10-Q and other cautionary statements set forth elsewhere in this report.

46

Interest Rate Risk 

Our interest rate risk management practices are aimed at optimizing net interest income, while guarding against deterioration that could be caused by certain interest rate scenarios. Interest rate sensitivity varies with different types of interest-earning assets and interest-bearing liabilities. We attempt to maintain interest-earning assets, comprised primarily of both loans and investments, and interest-bearing liabilities, comprised primarily of deposits, maturing or repricing in similar time horizons in order to manage any impact from market interest rate changes according to our risk tolerances. The Company uses a simulation model to measure the sensitivity to changing rates on earnings and economic value of equity (“EVE”). EVE is a longer term measure of interest rate risk and is based on the discounted cash flow or market value of each asset and liability category on the balance sheet.

The Company determines the sensitivity of its short-term future earnings and EVE to a hypothetical plus or minus 100 to 300 basis point parallel rate shock through the use of simulation modeling. The simulation includes the modeling of the balance sheet as an ongoing entity. Future business assumptions involving administered rate products, prepayments for future rate-sensitive balances, and the reinvestment of maturing assets and liabilities are included. These items are then modeled to project net interest income and EVE based on a hypothetical change in interest rates. The resulting net interest income for the next 12-month period and the EVE is compared to the baseline amounts calculated using flat rates. The difference represents the Company’s sensitivity to a positive or negative 100 basis points parallel rate shock.

The following table summarizes the expected impact of interest rate shocks on net interest income and EVE at March 31, 2023:

Rate Shock	Annual % change in net interest income	Percentage change in economic value of equity
+ 300 bp	9.8%	6.6%
+ 200 bp	6.6%	4.7%
+ 100 bp	3.3%	2.5%
- 100 bp	(3.5)%	(3.9)%
- 200 bp	(7.8)%	(9.3)%
- 300 bp	(12.4)%	(16.8)%

In addition to the rate shocks shown in the table above, the Company models net interest income under various dynamic interest rate scenarios. In general, changes in interest rates are positively correlated with changes in net interest income.

The Company occasionally uses interest rate derivative instruments as an asset/liability management tool to hedge mismatches in interest rate exposure indicated by the net interest income simulation described above. They are used to modify the Company’s exposures to interest rate fluctuations and provide more stable spreads between loan yields and the rate on their funding sources. At March 31, 2023, the Company had derivative contracts to manage interest rate risk, including $250.0 million in notional value on derivatives to hedge the cash flows on floating rate loans and $62.0 million in notional value on derivative on floating rate debt. Derivative financial instruments are also discussed in “Item 1. Note 6 – Derivative Financial Instruments.”

The FCA has announced that the most common USD LIBOR settings (overnight, 1-month. 3-month, 6-month and 12-month) will cease publication after September 30, 2024. However, LIBOR rates published after June 30, 2023 will be based on a “synthetic” methodology. LIBOR is commonly referenced in financial instruments. With the cessation of LIBOR, the Company has selected term SOFR as the replacement index for the majority of its variable rate loans and began providing customer notifications in early 2023. The Company ceased using LIBOR and ICE swap rates in new contracts and began issuing SOFR based loans in December 2021.

We have exposure to LIBOR in various financial contracts. Instruments that may be impacted include loans, debt instruments and derivatives, among other financial contracts indexed to LIBOR. We have an internal working group

47

composed of members from legal, credit, finance, operations, risk and audit to monitor developments, develop policies and procedures, assess the impact to the Company from the replacement index for affected contracts that expire after the expected discontinuation of representative LIBOR on June 30, 2023. Amending certain contracts indexed to LIBOR may require consent from the counterparties which could be difficult and costly to obtain in certain circumstances. As of March 31, 2023, the Company’s financial contracts indexed to LIBOR included $375.8 million in loans, $74.9 million in borrowings, and $546.2 million (notional) in derivatives.

In addition, LIBOR may be referenced in other financial contracts not included in the discussion above.

The Company had $6.3 billion in variable rate loans at March 31, 2023. Of these loans, $3.7 billion have an interest rate floor and nearly all of those loans were at or above the floor. $375.8 million in variable rate loans are indexed to LIBOR, $3.0 billion are indexed to the prime rate, $2.2 billion are indexed to SOFR, and $726.8 million are indexed to other rates.

At March 31, 2023, the Company’s available-for-sale and held-to-maturity investment securities totaled $1.6 billion and $720.7 million, respectively. These portfolios consists primarily of fixed-rate securities that are subject to changes in market value due to changes in interest rates. At March 31, 2023, net unrealized losses were $161.6 million and $65.0 million on the available-for-sale and held-to-maturity investment portfolios, respectively.

ITEM 4: CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the Company’s Chief Executive Officer (CEO) and the Chief Financial Officer (CFO), management has evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-15, as of March 31, 2023. Disclosure controls and procedures include without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Based on that evaluation, the CEO and CFO concluded the Company’s disclosure controls and procedures were effective as of March 31, 2023 to provide reasonable assurance of the achievement of the objectives described above.

Changes to Internal Controls

There were no changes during the period covered by this Quarterly Report on Form 10-Q in the Company’s internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, those controls.

PART II - OTHER INFORMATION

ITEM 1: LEGAL PROCEEDINGS

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 legal proceedings pending or threatened against the Company or its subsidiaries, 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.

ITEM 1A: RISK FACTORS

48

For information regarding risk factors affecting the Company, please see the cautionary language regarding forward-looking statements in the introduction to Item 2 of Part I of this Quarterly Report on Form 10-Q, and Part I, Item 1A of our Report on Form 10-K for the fiscal year ended December 31, 2022, which is supplemented by the additional risk factor set forth below.

Adverse developments affecting the banking industry, and resulting media coverage, have eroded customer confidence in the banking system and could have a material effect on the Company’s operations and/or stock price.

The recent high-profile bank failures involving Silicon Valley Bank and Signature Bank have generated significant market volatility among publicly traded bank holding companies and, in particular, regional banks. These market developments have negatively impacted customer confidence in the safety and soundness of regional banks. As a result, customers may choose to maintain deposits with larger financial institutions or invest in higher yielding short-term fixed income securities, all of which could materially adversely impact our liquidity, cost of funding, loan funding capacity, net interest margin, capital and results of operations. In connection with high-profile bank failures, uncertainty and concern has been, and may be in the future, compounded by advances in technology that increase the speed at which deposits can be moved, as well as the speed and reach of media attention, including social media, and its ability to disseminate concerns or rumors, in each case potentially exacerbating liquidity concerns. While the Department of the Treasury, the Federal Reserve, and the FDIC have made statements ensuring that depositors of recently failed banks would have access to their deposits, including uninsured deposit accounts, there is no guarantee that such actions will be successful in restoring customer confidence in regional banks and the banking system more broadly. In addition, the banking operating environment and public trading prices of banking institutions can be highly correlated, in particular during times of stress, which could adversely impact the trading prices of our common stock and potentially our results of operations. For more information on the Company's liquidity position, please see the “Deposits” and “Liquidity and Capital Resources” sections of Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations.

Summary of Significant Accounting Policies

Mar. 31, 2023

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, Florida, Kansas, Missouri, Nevada, and New Mexico through its banking subsidiary, Enterprise Bank & Trust.

Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2023. 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, 2022, 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, 2022.

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

On January 1, 2023, the Company adopted 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 charge-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 adoption of this update did not have a material effect on the Company’s consolidated financial statements.

FASB ASU 2021-01, Reference Rate Reform (Topic 848): Scope (ASU 2021-01). ASU 2021-01 was issued in January 2021 and provides 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, where 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. In December 2022, ASU 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset date of Topic 848 was issued, which extends the sunset date from December 31, 2022 to December 31, 2024.

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) 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) amend a related illustrative example, and (3) 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 has evaluated the accounting and disclosure requirements of ASU 2022-03 and does not expect them to have a material effect on the consolidated financial statements.

FASB ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 was issued in March 2023 to allow reporting entities to consistently account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. If certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits, instead of only low-income-housing tax credit (“LIHTC”) structures. This amendment also eliminates certain LIHTC-specific guidance aligning the accounting with other equity investments in tax credit structures. 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 2023-02 and does not expect them to have a material effect on the consolidated financial statements.

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS PER SHARE

Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method.

The following table presents a summary of per common share data and amounts for the periods indicated.

	Three months ended March 31,
(in thousands, except per share data)	2023		2022
Net income available to common shareholders	$	54,800	$	46,464
Weighted average common shares outstanding	37,305		37,788
Additional dilutive common stock equivalents	182		70
Weighted average diluted common shares outstanding	37,487		37,858
Basic earnings per common share:	$	1.47	$	1.23
Diluted earnings per common share:	1.46		1.23

For the three months ended March 31, 2023 and 2022, common stock equivalents of approximately 311,000 and 276,000, respectively, were excluded from the earnings per share calculations because their effect would have been anti-dilutive.

The balance of held-to-maturity securities in the “Amortized Cost” column in the table above includes a cumulative net unamortized unrealized gain of $16.8 million and $17.6 million at March 31, 2023 and December 31, 2022, respectively. Such amounts are amortized over the remaining life of the securities.

At March 31, 2023 and December 31, 2022, 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 $1.8 billion and $734.5 million at March 31, 2023 and December 31, 2022, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions, in addition to collateral securing borrowing bases with the FHLB and the Federal Reserve.

The amortized cost and estimated fair value of debt securities at March 31, 2023, 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 6 years.

The unrealized losses at both March 31, 2023 and December 31, 2022 were attributable primarily to changes in market interest rates after the securities were purchased. In March 2023, the Company established an allowance for credit losses on available-for-sale investment securities through a provision for credit losses of $4.8 million and subsequently charged-off $4.8 million. The charge-off related to the impairment of a debt security from a bank that

failed in 2023. At each of March 31, 2023 and December 31, 2022, the Company had no allowance recorded on available-for-sale securities.

Accrued interest receivable on held-to-maturity debt securities totaled $6.6 million and $5.8 million at March 31, 2023 and December 31, 2022, 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 $0.9 million at March 31, 2023 and $0.7 million at December 31, 2022.

The Company sold $28.4 million of available-for-sale securities in January 2023 for a gain of $0.4 million. There were no sales of available-for-sale investment securities during the three months ended March 31, 2022.

Other Investments

At March 31, 2023 and December 31, 2022, other investments totaled $62.9 million and $63.8 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 $14.0 million at both March 31, 2023 and December 31, 2022 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 loan balance at March 31, 2023 and December 31, 2022, includes a net premium on acquired loans of $10.3 million and $11.9 million, respectively. At March 31, 2023 and December 31, 2022, loans of $3.4 billion and $2.8 billion, respectively, were pledged to FHLB and the Federal Reserve Bank.

Accrued interest receivable totaled $44.7 million and $48.1 million at March 31, 2023 and December 31, 2022, respectively, and was reported in “Other Assets” on the consolidated balance sheets.

SBA 7(a) guaranteed loans sold during the three months ended March 31, 2023 totaled $8.8 million, resulting in a gain on sale of $0.5 million. There were no SBA loan sales during the same period in 2022.

A summary of the activity in the ACL on loans by category for the three months ended March 31, 2023 and 2022 is as follows:

(in thousands)	Commercial and industrial		CRE - investor owned		CRE - owner occupied		Construction and land development		Residential real estate		Other		Total

The ACL on sponsor finance loans, which is included in the categories above, represented $21.0 million and $16.1 million, respectively, as of March 31, 2023 and December 31, 2022.

The CECL methodology incorporates various economic scenarios. 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 $14.2 million to the ACL over the baseline model at March 31, 2023. These forecasts incorporate an expectation that the Federal Reserve will continue quantitative tightening and raise the federal funds rate to 5.00% to 5.25% in 2023 and that the recent bank failures are not an indication of a broader problem in the industry. The Company has also recognized various risks posed by loans in certain segments, including the hospitality and commercial office sectors, 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 market reactions to the Federal Reserve policy actions that could push the economy into a recession, persistently higher inflation, tightening in the credit markets, and further weakness in the financial system.

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 March 31, 2023, the ACL on loans included a qualitative adjustment of approximately $43.2 million. Of this amount, approximately $13.8 million was allocated to sponsor finance loans due to their unsecured nature.

The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon origination or acquisition. 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. The Company 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. 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.

The most common concession the Company provides to borrowers experiencing financial difficulty is a term extension. In limited circumstances, the Company may modify loans by providing principal forgiveness or an interest rate reduction. When principal forgiveness is provided, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses.

In some cases, the Company will modify a loan by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as an interest rate reduction or principal forgiveness, may be granted.

The following table shows loans modified to borrowers experiencing financial difficulty, disaggregated by loan class and type of concession granted:

	Term Extension
(in thousands)	March 31, 2023		% of Total Class of Financing Receivable
Commercial and industrial	$	22,818	0.57	%
Real estate:
Construction and land development	1,201		0.18	%
Total	$	24,019

The term extensions were for 2-12 months, and all loans were current under the modified terms.

There were no loans restructured during the three months ended March 31, 2022, and no troubled debt restructurings subsequently defaulted during the three months ended March 31, 2022.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, payment experience, credit documentation, current economic factors and other factors. 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 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 – Special Mention credits are borrowers that 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 business. 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)	March 31, 2023		December 31, 2022
Commitments to extend credit	$	3,053,927	$	3,113,966
Letters of credit	94,361		68,544

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 March 31, 2023 and December 31, 2022, approximately $249.7 million and $246.5 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 $10.2 million and $12.1 million for estimated losses attributable to the unadvanced commitments at March 31, 2023 and December 31, 2022, 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 March 31, 2023, the approximate remaining terms of standby letters of credit range from 1 month to 10 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.

For hedges of the Company’s variable-rate loans, interest rate swaps designated as cash flow hedges involve the receipt of fixed amounts and the Company making variable rate payments. In the fourth quarter 2022, the Company executed a cash flow hedge to reduce a portion of variability in cash flows on the Company’s prime based loan portfolio. The interest rate swap has a notional value of $100.0 million, that effectively fixes the interest rate at 6.63% for the notional amount and has a maturity date of January 1, 2028. In January 2023, the Company entered

into another hedge on the prime based loan portfolio with a notional value of $50.0 million, that effectively fixes the interest rate at 6.56% for the notional amount and has a maturity date of February 1, 2027.

In addition, the Company executed a prime based interest rate collar in the fourth quarter 2022 with a notional amount of $100.0 million. The collar includes a cap of 8.14% and a floor of 5.25%. This transaction, commonly referred to as a zero cost collar, involves the Company selling an interest rate cap where payments will be made when the index exceeds the cap rate, and the purchase of a floor where payments will be received if the index falls below the floor. The collar matures on October 1, 2029.

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 of 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 income or 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 income or expense as interest payments are paid on the Company’s variable-rate loans and debt. During the next twelve months, the Company estimates an additional $1.8 million will be reclassified as a decrease to interest income and $1.3 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

As of March 31, 2023, the fair value of derivatives in a net liability position was $16.1 million, which includes accrued interest but excludes any adjustment for nonperformance risk. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and posts collateral related to derivatives in a net liability position. Furthermore, the Company has received cash collateral from derivative counterparties on contracts in a net asset position as noted in the tables above.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

On January 1, 2023, the Company adopted 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 charge-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 adoption of this update did not have a material effect on the Company’s consolidated financial statements.

FASB ASU 2021-01, Reference Rate Reform (Topic 848): Scope (ASU 2021-01). ASU 2021-01 was issued in January 2021 and provides 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, where 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. In December 2022, ASU 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset date of Topic 848 was issued, which extends the sunset date from December 31, 2022 to December 31, 2024.

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) 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) amend a related illustrative example, and (3) 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 has evaluated the accounting and disclosure requirements of ASU 2022-03 and does not expect them to have a material effect on the consolidated financial statements.

FASB ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 was issued in March 2023 to allow reporting entities to consistently account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. If certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits, instead of only low-income-housing tax credit (“LIHTC”) structures. This amendment also eliminates certain LIHTC-specific guidance aligning the accounting with other equity investments in tax credit structures. 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 2023-02 and does not expect them to have a material effect on the consolidated financial statements.
