NOTE 1 -SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by the Company 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, and SBA loan and deposit productions offices throughout the country through its banking subsidiary, Enterprise Bank & Trust.

Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2024. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, 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 pursuant to the rules and regulations of the SEC. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information presented not misleading. 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, 2023.

The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated.

In the opinion of management, the consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the statements of financial position, results of operations, and cash flow for the interim periods.

Recent Accounting Pronouncements

FASB ASU 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 adoption of ASU 2022-03 did not 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 adoption of ASU 2023-02 did not have a material effect on the consolidated financial statements.

FASB ASU 2023-07, Improvements to Reportable Segment Disclosures. ASU 2023-07 was issued in November 2023 to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment disclosures. The amendments in this update require annual and interim disclosures on significant segment expenses that are regularly provided to the chief operating decision maker and require annual and interim disclosures on “other segment items” that comprise the difference between segment revenue less segment expense compared to the reported measure of segment profit or loss. In addition, the amendments will require all annual disclosures that are currently required to be reported on an interim basis and requires disclosure of the title and position of the chief operating decision maker and how that position uses the information to assess segment performance and the allocation of resources. ASU 2023-07 also requires entities that have a single reportable segment, such as the Company, to provide all disclosures required in this update and the existing segment disclosures in Topic 280. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is evaluating the accounting and disclosure requirements of ASU 2023-07 and does not expect them to have a material effect on the consolidated financial statements.

FASB ASU 2023-09, Income Tax Disclosures. ASU 2023-09 was issued in December 2023 to require annual disclosures on specific categories in the income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. Annual disclosures are required on income taxes paid, including the amounts paid for federal, state and foreign taxes and the amount paid in individual jurisdictions if the amount is equal to or greater than 5% of total income taxes paid (net of refunds received). Additional annual disclosures are required on pre-tax income from continuing operations and income tax expense, disaggregated by domestic and foreign amounts. The amendments in this update are effective for fiscal years beginning after December 15, 2024. The Company is evaluating the accounting and disclosure requirements of ASU 2023-09 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.

For the three and six months ended June 30, 2024, common stock equivalents of approximately 634,000 and 621,000, respectively, were excluded from the earnings per share calculations because their effect would have been anti-dilutive. Comparatively, there were 462,000 and 411,000 common stock equivalents excluded in the three and six months ended June 30, 2023, respectively.

NOTE 3 -INVESTMENTS

The following tables present the amortized cost, gross unrealized gains and losses, allowance for credit losses and fair value of securities available for sale and held to maturity:

The balance of held-to-maturity securities in the “Amortized Cost” column in the table above includes a cumulative net unamortized unrealized gain of $12.5 million and $14.1 million at June 30, 2024 and December 31, 2023, respectively. Such amounts are amortized over the remaining life of the securities.

At June 30, 2024 and December 31, 2023, 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 of $1.2 billion and $1.6 billion at June 30, 2024 and December 31, 2023, 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 Bank.

The amortized cost and estimated fair value of debt securities at June 30, 2024, 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 four years.

The following tables presents a summary of available-for-sale investment securities in an unrealized loss position:

The unrealized losses at both June 30, 2024 and December 31, 2023 were attributable primarily to changes in market interest rates after the securities were purchased. At each of June 30, 2024 and December 31, 2023, the Company didnot have an allowance for credit losses on available-for-sale securities.

Accrued interest on held-to-maturity debt securities totaled $6.9 million and $6.5 million at June 30, 2024 and December 31, 2023, 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 $0.3 million at June 30, 2024 and $0.8 million at December 31, 2023.

There wereno sales of available-for-sale securities during neither the three and six months ended June 30, 2024, nor the three months ended June 30, 2023. The Company sold $28.4 million of available-for-sale securities during the six months ended June 30, 2023 for a gain of $0.4 million.

Other Investments

At June 30, 2024 and December 31, 2023, other investments totaled $72.0 million and $66.2 million, respectively. As a member of the FHLB system administered by the Federal Housing Finance Agency, the Bank is required to maintain a minimum investment in capital stock with the FHLB consisting of membership stock and activity-based stock. The FHLB capital stock of $12.2 million at June 30, 2024 and $7.8 million at December 31, 2023 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 Small Business Investment Companies, Community Development Financial Institutions, private equity investments, and the Company’s investment in unconsolidated trusts used to issue trust preferred securities to third parties.

NOTE 4 -LOANS

The following table presents a summary of loans by category:

The loan balance includes a net premium on acquired loans of $9.2 million and $9.6 million at June 30, 2024 and December 31, 2023, respectively. At June 30, 2024 and December 31, 2023, loans and securities of $5.5 billion and $4.8 billion, respectively, were pledged to FHLB and the Federal Reserve Bank.

Accrued interest totaled $70.1 million and $66.7 million at June 30, 2024 and December 31, 2023, respectively, and was reported in “Other Assets” on the consolidated balance sheets.

SBA 7(a) guaranteed loans sold during the six months ended June 30, 2024 totaled $23.1 million, resulting in a gain on sale of $1.4 million. SBA 7(a) guaranteed loans sold during the six months ended June 30, 2023 totaled $8.8 million, resulting in a gain on sale of $0.5 million. There wereno sales in the three months ended June 30, 2024 and 2023, respectively.

No consumer mortgage loans secured by residential real estate were in the process of foreclosure at June 30, 2024, compared to $1.0 million at December 31, 2023.

A summary of the activity, by loan category, in the ACL on loans for the three and six months ended June 30, 2024 and 2023 is as follows:

The ACL on sponsor finance loans, which is included in the categories above, represented $19.9 million and $23.0 million, respectively, as of June 30, 2024 and December 31, 2023.

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 $14.6 million to the ACL on loans over the baseline model at June 30, 2024. The baseline forecast incorporates an expectation that the federal funds rate has peaked at the range of 5.25% to 5.50% and will begin falling in the latter half of 2024. It is also assumed that the bank failures in early 2023 were 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 commercial office and agricultural 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 CECL model. Included in these risks are 1) changes in lending policies and procedures, 2) actual and expected changes in business and economic conditions, 3) changes in the nature and volume of the portfolio, 4) changes in lending management, 5) changes in volume and the severity of past due loans, 6) changes in the quality of the loan review system, 7) changes in the value of underlying collateral, 8) the existence and effect of concentrations of credit and 9) other factors such as the regulatory, legal and competitive environments and events such as natural disasters and pandemics. At June 30, 2024, the ACL on loans included a qualitative adjustment of approximately $42.2 million. Of this amount, approximately $12.6 million was allocated to Sponsor Finance loans due to their mostly unsecured nature.

The current year-to-date gross charge-offs by loan class and year of origination is presented in the following tables:

The following tables present the recorded investment in nonperforming loans by category, excluding government guaranteed balances:

The nonperforming loan balances at June 30, 2024 and December 31, 2023 exclude government guaranteed balances of $12.9 million and $10.7 million respectively.

Interest income recognized on nonaccrual loans was immaterial during the three and six months ended June 30, 2024 and 2023.

Collateral-dependent nonperforming loans by class of loan is presented as of the dates indicated:

The aging of the recorded investment in past due loans by class and category is presented as of the dates indicated.

The allowance for credit losses on loans 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 on loans is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. The Company uses a probability of default and loss given default model to determine the allowance for credit losses on loans.

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 on loans 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 on loans. 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 on loans.

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 tables show the recorded investment at the end of the dates listed for loans modified to borrowers experiencing financial difficulty, disaggregated by loan class and type of concession granted:

The following tables summarize the financial impacts of loan modifications made to borrowers experiencing financial difficulty and outstanding at the date indicated:

The following table shows the aging of the recorded investment in modified loans in the last 12 months by class at the date indicated:

The following table summarizes loans that experienced a default during the six months ended June 30, 2024, subsequent to being granted a modification in the preceding twelve months. All of these loans were charged off during the preceding period. There wereno loans that experienced a default during the three months ended June 30, 2024, subsequent to being granted a modification in the preceding twelve months.

As of June 30, 2023, commercial and industrial loans totaling $0.7 million experienced a default subsequent to being granted a term extension modification in the prior twelve months. Default is defined as movement to nonperforming status, foreclosure or charge-off.

As of June 30, 2024, the Company allocated an immaterial amount in specific reserves to loans that have been restructured.

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, and current economic factors among 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 also include circumstances where the borrower is starting to reverse a negative trend or condition, or has recently been upgraded from a 7, 8, or 9 rating.

•Grade 7 – Special Mention credits are borrowers that have experienced financial setback of a nature that is not determined to be severe or influence ‘ongoing concern’ expectations. Although possible, no loss is anticipated, 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 non-accrual.

The recorded investment by risk category of the loans by class and year of origination is presented in the following tables as of the dates indicated:

In the tables above, loan originations in 2024 and 2023 with a classification of “special mention” or “classified” primarily represent renewals or modifications initially underwritten and originated in prior years.

For certain loans, the Company evaluates credit quality based on the aging status.

The following tables present the recorded investment on loans based on payment activity as of the dates indicated:

NOTE 5 -COMMITMENTS AND CONTINGENT LIABILITIES

The Company issues financial instruments in the normal course of its business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is not more than 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 significant off-balance-sheet financial instruments are as follows:

Off-Balance Sheet Credit Risk

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at June 30, 2024 and December 31, 2023, $182.8 million and $191.6 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 obligations. 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 $5.9 million and $6.6 million for estimated losses attributable to the unadvanced commitments at June 30, 2024 and December 31, 2023, respectively.

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. As of June 30, 2024, the approximate remaining terms of standby letters of credit range from 1 month to 9 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 loans and 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 income and 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. The Company has executed cash flow hedges to reduce a portion of variability in cash flows on the Company’s prime based loan portfolio. Select terms of the hedges are as follows:

In addition, the Company has a prime based interest rate collar 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 became effective on October 27, 2022 and matures on October 1, 2029.

For hedges of variable-rate liabilities, 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. The Company has executed a series of cash flow hedges to fix the effective interest rate for payments due on $32.1 million of junior subordinated debentures to a weighted-average-fixed rate of 2.64%.

Select terms of the hedges are as follows:

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 $0.8 million will be reclassified as a decrease to interest expense and $2.3 million will be reclassified as a decrease to interest income.

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 as well as their classification on the Balance Sheet:

The table below presents a gross presentation, the effects of offsetting, and a net presentation of the Company’s financial instruments subject to offsetting. The gross amounts of assets or liabilities can be reconciled to the tabular disclosure of fair value. The fair value table above provides the location of financial assets and liabilities presented on the Balance Sheet.

As of June 30, 2024, the fair value of derivatives in a net liability position, which includes accrued interest, was $17.4 million. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and posts collateral related to derivatives in a net liability position. The Company has received cash collateral from derivative counterparties on contracts in a net asset position as noted in the tables above.

NOTE 7 -FAIR VALUE MEASUREMENTS

The following table summarizes financial instruments measured at fair value on a recurring basis segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

From time to time, the Company measures certain assets at fair value on a nonrecurring basis. These include assets measured at the lower of cost or fair value that were recognized at fair value below cost at the end of the period. The amounts reported in the following tables include balances measured at fair value during the reporting period and still held as of the reporting date.

Following is a summary of the carrying amounts and fair values of certain financial instruments:

For information regarding the methods and assumptions used to estimate the fair value of each class of financial instruments refer to Note 18 –Fair Value Measurements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC.
