St. Louis, Mo. October 25, 2021 – Enterprise Financial Services Corp (Nasdaq: EFSC) (the “Company” or “EFSC”) reported net income of $13.9 million for the third quarter 2021, a decrease of $24.5 million compared to the linked second quarter (“linked quarter”) and a decrease of $4.0 million from the prior year quarter. Earnings per diluted share (“EPS”) was $0.38 for the third quarter 2021, compared to $1.23 and $0.68 for the linked and prior year quarters, respectively. Excluding merger-related, branch closure expenses and the FCBP CECL double count charge, adjusted EPS2, adjusted ROAA2, and adjusted ROATCE2 for the third quarter 2021 were $1.27, 1.51% and 18.15%, respectively.

Net income and earnings per share in the current quarter were impacted by the following items:

($ in thousands, except per share data)	Net Income (pretax)		EPS
Merger-related expenses	$	(14,671)	$	(0.31)
FCBP CECL double count	(25,353)		(0.51)

Jim Lally, EFSC’s President and Chief Executive Officer, commented, “Our third quarter results included a record pre-provision net revenue1 of $56 million, or 1.81% of average assets. Our results were bolstered by the acquisition of FCBP that closed during the quarter, furthering our commercial banking capabilities in the Southern California market. This augments our Southwest presence, and when combined with our specialty loan and deposit business lines, supports our overall growth initiatives. Additionally, we recently received a $60.0 million allocation from the New Market Tax Credit program that will enable us to continue supporting our communities through our CDE, while also enhancing our tax credit lending specialty. I am pleased with our financial results and the actions we have taken this quarter to strengthen our franchise.”

* Non-GAAP measures. Refer to discussion and reconciliation of these measures in the accompanying financial tables. Calculations not adjusted for increase in average deposits or increase in deposit expense, as applicable.

•Asset quality - The allowance for credit losses to total loans was 1.67% at September 30, 2021, compared to 1.77% at June 30, 2021 and 2.01% at September 30, 2020. The allowance for credit losses on the acquired FCBP loan portfolio was approximately 1.57%, which primarily contributed to the reduction of the ratio of the allowance for credit losses to total loans at September 30, 2021 as compared to the prior periods presented. Nonperforming assets to total assets was 0.35% at September 30, 2021 compared to 0.44% and 0.53% at June 30, 2021 and September 30, 2020, respectively.

•Deposits - Total deposits increased $2.2 billion from the linked quarter to $10.8 billion as of September 30, 2021, primarily due to the addition of FCBP deposits of $1.9 billion. Average deposits totaled $10.3 billion for the quarter ended September 30, 2021 compared to $8.6 billion and $6.7 billion for the linked and prior year quarters, respectively. Noninterest-bearing deposit accounts represented 40.4% of total deposits, and the loan to deposit ratio was 84.2% at September 30, 2021.

•Capital - Total shareholders’ equity was $1.4 billion and the tangible common equity to tangible assets ratio3 was 8.4% at September 30, 2021, compared to 8.3% at June 30, 2021. The Bank’s regulatory capital ratios remain “well-capitalized,” with a common equity tier 1 ratio of 12.3% and a total risk-based capital ratio of 13.4% as of September 30, 2021. The Company’s common equity tier 1 ratio and total risk-based capital ratio was 11.2% and 14.5%, respectively, at September 30, 2021.

The Company issued 7,808,459 shares totaling $343.7 million in the third quarter 2021 as merger consideration in connection with the FCBP acquisition.

The Company has 1,277,951 shares available for repurchase under its common stock repurchase authorization. The Company repurchased 470,412 shares totaling $21.2 million in the third quarter 2021 for an average price of $45.15 per share. Total shares repurchased year-to-date total 722,049 at an average price of $45.80.

The Company intends to redeem its $50.0 million fixed-to-floating subordinated debentures on the first call date of November 1, 2021.

The Company’s Board of Directors unanimously approved a quarterly dividend of $0.20 per common share, payable on December 31, 2021 to shareholders of record as of December 15, 2021, an increase of $0.01, or 5.0%, compared to the third quarter.

3 Tangible common equity to tangible assets ratio is a non-GAAP measure. Refer to discussion and reconciliation of this measure in the accompanying financial tables.

•Liquidity - The Company maintains a high level of both on-balance-sheet and off-balance-sheet liquidity. At September 30, 2021, on-balance-sheet liquidity consisted of cash and unpledged investment securities of $1.2 billion. Off-balance-sheet liquidity totaled $1.8 billion through the Federal Home Loan Bank, Federal Reserve and correspondent bank lines. The Company also has an unused $25 million revolving line of credit at the holding company and has an effective shelf registration statement on file with the U.S. Securities and Exchange Commission allowing for the issuance of various forms of equity and debt securities.

•Branch Consolidation - As part of the integration of FCBP, the Company commenced the process to close three branch locations in California. A lease and fixed asset impairment charge of $0.4 million was recognized and reported in merger expenses. The Company expects to realize annual cost savings of approximately $0.8 million. Additionally, the Company has also commenced the process to close two branches in St. Louis and consolidate the operations and customers of these branches with other nearby locations. An impairment charge of $3.4 million on these branches was recognized in the third quarter 2021 for buildings, leases and fixed assets. The Company expects to realize annual cost savings of approximately $1.5 million on these two branches. These branch closures are reflective of current trends in the industry and traffic as a result of technology adoption and other business climate trends.

Net interest income for the third quarter increased $15.6 million to $97.3 million from $81.7 million in the linked quarter, and increased $33.9 million from the prior year period. NIM, on a tax equivalent basis, was 3.40% for the third quarter, compared to 3.46% in the linked quarter, and 3.29% in the third quarter 2020. The increase in net interest income from the linked quarter was primarily due to greater average earning assets resulting from the FCBP acquisition. Interest income increased mainly due to a $1.4 billion increase in average loans compared to the linked period, including $1.5 billion of average loans acquired from FCBP, partially offset by reduced income from PPP loans and other purchase accounting income. While PPP loans (excluding FCBP acquired PPP loans) decreased $164.0 million in the current quarter, forgiveness of these loans by the SBA accelerated deferred loan fees into income that benefits net interest margin. The increase in interest income was partially offset by higher interest expense related to the addition of $685 million of interest bearing liabilities from FCBP.

NIM decreased six basis points from the linked quarter to 3.40% during the current quarter primarily due to a ten basis point decrease in earning asset yields. The decrease in the earning asset yield was primarily due to higher levels of cash related to payoffs of PPP loans and deposit growth (14 bps), an increased balance and lower yields on investment securities (2 bp), and lower purchase accounting accretion on legacy Enterprise loans (6 bps), partially offset by higher loan yields (4 bps) and the addition of higher yielding loans from FCBP (9 bps). The cost of interest-bearing liabilities declined two basis points from the linked quarter, primarily due to lower rates on time deposits (1 bp) and the addition of low cost deposits from FCBP (1 bp).

a Amounts reported are as of September 30, 2021 and are separately shown attributable to the FCBP loan portfolio acquired on July 21, 2021, and the Company’s pre-FCBP acquisition loan portfolio.
b Excluding PPP and purchase accounting adjustments, FCBP gross loans increased $71.8 million from acquisition on July 21, 2021.
c $1.2 billion is attributable to the Seacoast loan portfolio acquired on November 12, 2020.

Loans totaled $9.1 billion at September 30, 2021, increasing $1.9 billion compared to the linked quarter. The acquisition of FCBP added $1.9 billion of loans, while legacy PPP loans declined $164.0 million. Excluding FCBP and PPP, loans grew $110.6 million, or 6%, on an annualized basis from the linked quarter. The increase was driven by C&I loans ($99.1 million) and a broad-based increase in specialty lending ($65.9 million). SBA loans represent

6

$28.2 million of the increase in specialty lending during the current quarter, primarily driven by the expansion of our SBA lending capabilities following our acquisition of Seacoast in the fourth quarter 2020. Year-over-year, loans increased $3.0 billion, or 48.8%. The year-over-year increase was primarily due to the FCBP and Seacoast acquisitions. For the quarter ended September 30, 2021 average line draw utilization was 38.2% compared to 38.9% and 40.4% for the linked quarter and prior-year quarter, respectively. Line draw usage for third quarter 2021 increased $265 million compared to the linked quarter.

Net charge-offs (recoveries)	$	1,850		$	869		$	5,647		$	(612)		$	1,027
*Excludes government guaranteed balances.

The provision for credit losses was $19.7 million for the third quarter 2021 compared to a benefit of $2.7 million for the linked quarter and a $14.1 million provision for the prior year quarter. A provision for credit losses of $23.9 million was recorded to establish the initial allowance for credit losses on FCBP non-PCD loans, which we refer to as the “CECL double-count” adjustment. An additional $1.4 million provision was recognized to establish the reserve for FCBP’s unfunded loan commitments. The provision for credit losses from the FCBP acquisition was offset by a $5.7 million provision benefit on the legacy loan portfolio due to a combination of improving economic forecasts and the Company’s stable credit quality.

Gross charge-offs of $4.3 million in the quarter primarily consisted of a loan that had previously defaulted and was fully reserved in a prior period. Net charge-offs to average loans for the third quarter 2021, the linked quarter, and the prior year quarter totaled eight basis points, five basis points and seven basis points, respectively.

aAmounts reported are as of September 30, 2021 and are shown separately attributable to the FCBP deposit portfolio acquired on July 21, 2021, and the Company’s pre-FCBP acquisition deposit portfolio.
b $1.1 billion is attributable to the Seacoast deposit portfolio acquired on November 12, 2020.

Total deposits at September 30, 2021 were $10.8 billion, an increase of $2.2 billion from June 30, 2021, and an increase of $4.2 billion from September 30, 2020. The increase from the linked quarter was primarily due to the FCBP acquisition, and the year-over-year increase was primarily due to the FCBP and Seacoast acquisitions.

Core deposits, defined as total deposits excluding certificates of deposits, were $10.2 billion at September 30, 2021, an increase of $2.1 billion from the linked quarter. FCBP core deposits were $1.7 billion at September 30, 2021. The Company’s participation in PPP, the low rate environment and high personal savings rate continues to contribute to the increase in deposits. Noninterest-bearing deposits were $4.4 billion at September 30, 2021, or 40.4% of total deposits. Specialty deposits increased $449.7 million over the linked quarter to $1.9 billion primarily attributable to community associations, third party escrow and FCBP deposit specialties. The total cost of deposits was 0.11% for the current quarter compared to 0.12% and 0.22% for the linked quarter and prior year quarter, respectively.

Noninterest Income

The following table presents a comparative summary of the major components of noninterest income for the periods indicated:

	Linked quarter comparison								Prior year comparison
	Quarter ended								Quarter ended
($ in thousands)	September 30, 2021		June 30, 2021		Increase (decrease)				September 30, 2020		Increase (decrease)

Total noninterest income	$	17,619	$	16,204	$	1,415	9	%	$	12,629	$	4,990	40	%

Total noninterest income for the third quarter 2021 was $17.6 million, an increase of $1.4 million from the linked quarter and an increase of $5.0 million from the prior year quarter. The increase from the linked quarter was

8

primarily due to tax credit income and deposit service charges, partially offset by a decline in miscellaneous income from a private equity fund distribution received in the second quarter. The increase from the prior year quarter was broad-based, reflecting higher volumes in tax credit activity, card services, wealth management and deposit service charges. FCBP noninterest income totaled $1.4 million in the third quarter, primarily in deposit service charges and servicing fees.

Noninterest Expenses

Noninterest expense was $76.9 million for the third quarter 2021, compared to $52.5 million for the linked quarter, and $39.5 million for the prior year quarter. The increase from the linked quarter was primarily due to merger-related expenses of $14.7 million (an increase of $12.7 million from the linked quarter), FCBP noninterest expense of $7.0 million, and branch closure expenses of $3.4 million.

For the third quarter 2021, the Company’s efficiency ratio was 66.9% compared to 53.6% and 52.0% for the linked quarter and prior year quarter, respectively. The Company’s core efficiency ratio4 improved to 51.3% for the quarter ended September 30, 2021, compared to 51.9% for the linked quarter and 51.0% for the prior year quarter.

4 Core efficiency ratio is a non-GAAP measure. Refer to discussion and reconciliation of this measure in the accompanying financial tables.

Income Taxes

The Company’s effective tax rate was 24% for the quarter ended September 30, 2021, compared to 20% for both the linked quarter and the prior year quarter. The increase reflects the impact of non-deductible merger expenses and an increase in state taxes that increased the effective tax rate approximately 3% in the current quarter.

Capital

The following table presents various EFSC capital ratios:

	Quarter ended
Percent	September 30, 2021		June 30, 2021		March 31, 2021		December 31, 2020		September 30, 2020
Total risk-based capital to risk-weighted assets	14.5	%	14.9	%	15.1	%	14.9	%	14.6	%
Tier 1 capital to risk weighted assets	12.2	%	12.3	%	12.3	%	12.1	%	11.6	%
Common equity tier 1 capital to risk-weighted assets	11.2	%	11.1	%	11.0	%	10.9	%	10.2	%
Tangible common equity to tangible assets	8.4	%	8.3	%	8.2	%	8.4	%	8.0	%

Total equity was $1.4 billion at September 30, 2021, an increase of $320.9 million from the linked quarter. The Company issued 7.8 million shares to FCBP shareholders as merger consideration totaling $343.7 million based on the closing stock price of the Company’s common stock on July 21, 2021, and repurchased $21.2 million of common stock in the third quarter 2021.The Company’s regulatory capital ratios continue to exceed the “well-capitalized” regulatory benchmark. Capital ratios for the current quarter are subject to, among other things, completion and filing of the Company’s regulatory reports and ongoing regulatory review.

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, PPNR ROAA, financial metrics adjusted for PPP impact, core efficiency ratio, and the tangible common equity ratio, in this release 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, PPNR ROAA, financial metrics adjusted for PPP impact, core efficiency ratio, and the tangible common equity ratio, collectively “core performance measures,” presented in this earnings release and the included tables as important measures of financial performance, even

9

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, 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.
