St. Louis, Mo. January 20, 2020. Enterprise Financial Services Corp (Nasdaq: EFSC) (the “Company” or “EFSC”) reported net income of $92.7 million, or $3.55 per diluted share, for the year ended December 31, 2019, compared to $89.2 million, or $3.83 per diluted share for the prior year period. Merger-related expenses from the Trinity acquisition reduced net income by $18.0 million pretax ($14.0 million after tax), or $0.53 per diluted share.

The Company recorded net income of $29.1 million for both the third and fourth quarters of 2019, or earnings per share of $1.08 and $1.09, respectively. Seasonally strong sales of tax credits in the fourth quarter offset the decline in incremental accretion income from the linked third quarter (“linked quarter”).

Dividends paid in 2019 of $0.62 per share increased $0.15 per share, or 32%, compared to $0.47 per share in 2018. The Company’s Board of Directors approved the Company’s quarterly dividend of $0.18 per common share for the first quarter of 2020, an increase from $0.17 for the prior quarter, payable on March 31, 2020 to shareholders of record as of March 16, 2020.

Jim Lally, EFSC’s President and Chief Executive Officer, commented, “We are pleased with another solid quarter of financial performance to close 2019. We achieved strong growth in both loans and deposits during the fourth quarter. On an annualized basis, loans grew 7% and deposits grew 10%. Given the current interest rate environment, I am pleased that our business fundamentals continued to generate robust earnings with a 1.6% return on average assets and a 19% return on average tangible common equity¹.”

Lally added, “2019 was a pivotal year, as we expanded our geographic presence into New Mexico with the acquisition and integration of Trinity, organically grew the balance sheet with quality loan and deposit relationships and strategically managed our capital position to provide a high return to our shareholders. Our continued success reflects the resolve of our associates to serve the customers and communities within our market areas.”

The Company closed its acquisition of Trinity on March 8, 2019. The results of operations of Trinity are included in our consolidated results from this date forward and are excluded from preceding periods.

Net Interest Income

For 2019, net interest income totaled $238.7 million, an increase of $46.8 million, or 24%, compared to $191.9 million in the prior year. Net interest margin, on a fully tax equivalent basis, was 3.80% for 2019 compared to 3.82% for the prior year. The increase in net interest income was primarily due to the Trinity acquisition and organic growth.

Net interest income for the fourth quarter of 2019 totaled $61.6 million, a decrease of $1.4 million, from the linked quarter. Interest rates continued to decline during the fourth quarter. Portfolio loan growth, combined with the Company’s ability to modestly reprice deposits, helped to deliver a consistent level of core net interest income¹ of $61.0 million for both the third and fourth quarter. The impact of lower interest rates on loan yields was offset by an increase in average loans, a decrease in the cost of interest-bearing liabilities and growth in noninterest-bearing deposits that resulted in a reduction in wholesale borrowings.

Core net interest income and core net interest margin noted in the table below exclude incremental accretion on non-core acquired loans.

The core net interest margin¹ decreased five basis points to 3.64% during the fourth quarter 2019 primarily due to a 26-basis point decrease in loan yields. This is a result of the decline of both the one-month LIBOR and Prime interest rates during the fourth quarter, which impacted the underlying interest rates of the Company’s loan portfolio, 59% of which is priced to variable interest rate indices. In response, the Company was successful in lowering the cost of interest-bearing transaction accounts and money market accounts by 12 basis points and 32 basis points, respectively, in the fourth quarter to partially offset the decrease in margin from the lower loan yield. Additionally, seasonal growth in noninterest-bearing deposits in the fourth quarter reduced the use of higher-cost wholesale borrowings.

The Company manages its balance sheet in part to defend against pressures on core net interest margin, which could be negatively impacted by continued competition for deposits, current interest rate conditions, and downward movement in short-term rates.

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. C&I loan growth, coupled with fixed-rate CRE lending, supports management’s efforts to maintain a flexible asset sensitive interest rate risk position.

Asset Quality

The following table presents the categories of nonperforming assets and related ratios for the most recent five quarters.

Nonperforming assets increased $8.7 million to $32.8 million at December 31, 2019 from $24.1 million at September 30, 2019. The increase was primarily from the addition of a $12.9 million nonaccrual loan, partially offset by a $2.2 million decrease in other nonaccrual loans and a $2.2 million decrease in other real estate. The addition of the $12.9 million nonaccrual loan did not significantly impact the provision for loan losses, as the reserve coverage on the loan had been primarily recorded in prior periods.

The Company recorded a provision for loan losses of $6.4 million in 2019, compared to $6.6 million in the prior year. In the fourth quarter 2019, the provision for loan losses was $1.3 million compared to $1.8 million in the linked quarter. Net charge-offs to average loans totaled 0.13% for both 2019 and 2018. The decrease in the ratio of allowance for loan losses to total loans to 0.81% at December 31, 2019, from 0.85% at September 30, 2019, was due to a 24% decrease in substandard loans and net charge-offs of $2.5 million.

aAmounts reported are as of March 31, 2019 and are shown separately attributable to the Trinity deposit portfolio and related operations acquired on March 8, 2019, and the Company’s pre-Trinity acquisition deposit portfolio and related operations.

Total deposits at December 31, 2019 were $5.8 billion, an increase of $146.6 million from September 30, 2019, and an increase of $1.2 billion, or 26%, from December 31, 2018. The increase over the prior year period was primarily due to the Trinity acquisition.

Core deposits, defined as total deposits excluding time deposits, were $4.9 billion at December 31, 2019, an increase of $140.2 million, or 12% on an annualized basis, from the linked quarter, and an increase of $1.0 billion, or 27%, from the prior year period.

Noninterest-bearing deposits increased $31.9 million compared to September 30, 2019, and increased $226.6 million compared to December 31, 2018. The total cost of deposits was 0.81% for the fourth quarter, reflecting the deposit repricing discussed previously, compared to 0.94% in the linked quarter and 0.95% in the prior year quarter.

Noninterest Income

Total noninterest income for 2019 was $49.2 million, an increase of $10.8 million, or 28%, from 2018. This improvement was primarily due to the following:

For the full year:

◦ Deposit service charges increased $1.1 million or 9%

◦ Wealth management revenue increased $1.7 million or 21%

◦ Income from card services increased $2.5 million or 37%

◦ Tax credit income increased $2.6 million or 91%

◦ Other income increased $2.7 million, or 31%, due to swap fees, sublease income, and BOLI income

The bullet points above are inclusive of $7.9 million attributed to the acquisition of Trinity.

For the quarter ended December 31, 2019, total noninterest income was $14.4 million, an increase of $0.9 million, or 6%, from the linked quarter. Noninterest income in the linked quarter included $1.3 million of gains on investment sales and loan workout income that did not reoccur in the fourth quarter. Tax credit income was seasonally strong at $3.4 million for the fourth quarter 2019, compared to $1.2 million in the linked third quarter, due primarily to state tax credit sales.

Noninterest Expenses

Noninterest expense for 2019 was $165.5 million, an increase of $46.5 million, or 39%, from 2018. The acquisition of Trinity contributed $24.5 million of the current year increase. In addition, merger-related expenses were $18.0 million in 2019. The Company’s efficiency ratio was 57.5% in 2019, compared to 51.7% for the prior year. The increase in 2019 was primarily due to merger-related expenses incurred for the Trinity acquisition. The Company’s core efficiency ratio¹ was 52.4% in 2019, compared to 52.0% for the prior year.

For the fourth quarter 2019, noninterest expense was $38.4 million, an increase of $0.1 million from the linked quarter. Included in the fourth quarter were other real estate owned valuation adjustments of $0.8 million that were partially offset by a decrease in other expenses. The fourth quarter efficiency ratio was 50.4% compared to 50.0% in the linked quarter. The Company’s core efficiency ratio¹ was 50.7% for the fourth quarter compared to 51.7% for the linked quarter. The decrease in the core efficiency ratio from the linked quarter is reflective of higher operating revenue, including seasonal tax credit income, and holding noninterest expense steady.

Income Taxes

The Company’s effective tax rate was 20.1% in 2019 compared to 14.7% for the prior year. The lower rate for the prior year resulted from a non-recurring reduction of income tax expense of $2.7 million from a tax planning election.

The effective tax rate was 19.9% for the fourth quarter of 2019, compared to 20.4% for the linked quarter. The Company expects its effective tax rate for 2020 to be approximately 20-21%.

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 adjusted EPS, core net interest income, core net interest margin, tangible common equity, core efficiency ratios, ROATCE, adjusted ROAA, adjusted ROAE, and adjusted ROATCE, 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 adjusted EPS, core net interest income, core net interest margin, core efficiency ratio, adjusted ROAA, adjusted ROAE, ROATCE, adjusted ROATCE, 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 though they are non-GAAP measures, as they provide supplemental information by which to evaluate the impact of non-core acquired loans, which were acquired from the FDIC and previously covered by loss share agreements, and the related income and expenses, the impact of certain non-comparable items, and the Company’s operating performance on an ongoing basis. Core performance measures include contractual interest on non-core acquired loans, but exclude incremental accretion on these loans. Core performance measures also exclude expenses directly related to non-core acquired loans. Core performance measures also 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.
