ENTERPRISE FINANCIAL REPORTS FIRST QUARTER 2015 RESULTS
Reported Highlights

• | Net income of $0.46 per diluted share, up more than 50% over the linked fourth quarter and the prior year period

• | Nonperforming assets decrease 33% from one year ago to 0.52% of total assets

Core Highlights1

• | Core net income of $0.35 per diluted share, up 6% over the linked fourth quarter, and 25% over the prior year first quarter

• | Core revenue increased 5% from the prior year period

• | Core efficiency ratio improved to 61%

St. Louis, April 23, 2015. Enterprise Financial Services Corp (NASDAQ: EFSC) (the “Company”) reported net income of $9.3 million for the quarter ended March 31, 2015, an increase of $3.4 million, or 57%, as compared to the linked fourth quarter. Net income per diluted share was $0.46 for the quarter ended March 31, 2015, an increase of 53% compared to $0.30 per diluted share for the linked fourth quarter. First quarter 2015 net income was 60% higher than the $5.8 million reported in the prior year period, and diluted earnings per share were 53% higher than the $0.30 reported a year ago. The increase in net income was primarily due to a decrease in noninterest expenses from improved expense control initiatives, and reversal of provision for loan losses of our purchase credit impaired ("PCI") loans due to higher expected cash flows.
On a core basis1, the Company reported net income of $7.1 million, or $0.35 per diluted share, for the quarter ended March 31, 2015, compared to $6.7 million, or $0.33 per diluted share, in the linked fourth quarter. The increase was due to lower provision for loan losses and reduced noninterest expenses. First quarter 2015 core net income increased 27% from $5.6 million for the prior year period, and diluted core earnings per share grew 25% from $0.28 for the prior year period. The increase was primarily due to increases in earning asset balances driving growth in core net interest income combined with a reduction in noninterest expenses.
Peter Benoist, President and CEO, commented, “First quarter reported earnings represented sizeable increases over the linked quarter and prior year period, largely as a result of revenue growth combined with lower operating costs. Importantly, Enterprise’s core earnings continued to climb in the quarter. Core earnings per share increased 25% year over year, driven by core revenue growth of 5% and continued strong expense management.”
“Our core net interest margin remained firm in the first quarter,” noted Benoist, “reflecting our focus on disciplined pricing on both sides of the balance sheet. Additionally, asset quality continued to improve over already strong levels. Nonperforming assets fell to 52 basis points of total assets and our reserve coverage of nonperforming loans grew to 200%.”
Benoist added, “Loans outstanding were relatively flat in the first quarter, after a 24% annualized increase last quarter. However, loan originations and advances remained strong - and pipelines are solid. We continue to expect loan growth at or above 10% for the full year.”

Net Interest Income
Net interest income in the first quarter decreased $1.8 million from the linked fourth quarter and $1.3 million from the prior year period due to lower balances of PCI loans, lower accelerated cash flows on PCI loans, and lower interest rates on newly originated loans. These items were partially offset by lower interest expense primarily related to the payoff of higher cost debt in the prior year. The net interest margin on a fully tax equivalent basis was 3.92% for the first quarter, compared to 4.13% in the linked fourth quarter, and 4.39% in the first quarter of 2014.
In the first quarter of 2015, the yield on PCI loans was 20.85%, as compared to 26.47% in the linked quarter and 26.09% in the prior year period.
The cost of interest-bearing deposits declined 2 basis points to 0.54% in the first quarter of 2015 from the linked fourth quarter and was 4 basis points lower than the first quarter of 2014, primarily from lower rates on time deposit balances. The cost of interest-bearing liabilities declined 7 basis points in the linked quarter to 0.56% and 12 basis points from the first quarter of 2014. The improvement was primarily due to the prepayment of $50 million of FHLB borrowings in December 2014 and the aforementioned improvement in deposit costs.
Core net interest margin1, defined as the net interest margin (fully tax equivalent), including contractual interest on PCI loans but excluding the incremental accretion on these loans, was as follows:

| For the Quarter ended
($ in thousands) | March 31, 2015 |  | December 31, 2014 |  | September 30, 2014 |  | June 30, 2014 |  | March 31, 2014
Core net interest margin1 | 3.46 | % |  | 3.45 | % |  | 3.41 | % |  | 3.41 | % |  | 3.44 | %
Core net interest income1 | 25,587 |  |  | 25,667 |  |  | 24,865 |  |  | 24,204 |  |  | 23,702 |

Core net interest income1 increased 8% compared to the prior year period due to strong portfolio loan growth in 2014 and managed decreases in the cost of interest-bearing liabilities as discussed above. Core net interest income remained stable at $25.6 million when compared to the linked fourth quarter despite two fewer days in the first quarter. Core net interest margin increased 1 basis point when compared to the linked quarter, primarily due to the effect of the FHLB debt prepayment in December 2014 and higher fees on loans, offset by lower contractual interest on PCI loans as the balances decline.
Core net interest margin1 increased 2 basis points from the prior year quarter primarily due to the managed reductions in funding costs combined with an improved earning asset mix. These factors mitigated continued pressure on portfolio loan yields and reductions in PCI loan balances, as those balances continue to run-off. Pressure on loan yields and continued reductions in PCI loan balances could lead to a further decline in core net interest margin in 2015.

Portfolio loans
Portfolio loans remained stable at $2.4 billion at March 31, 2015, increasing $1.6 million, when compared to the linked quarter. On a year over year basis, portfolio loans increased $262 million, or 12%. Strong fourth quarter growth combined with the timing of payoffs early in the first quarter of 2015 resulted in stable loan balances during the period. However, growth has been strong overall as average loans increased 10% on an annualized basis compared to the linked fourth quarter, and we continue to expect loan growth at or above 10% for 2015.
Commercial and industrial ("C&I") loans decreased $5.2 million during the first quarter of 2015 compared to the linked fourth quarter of 2014. C&I loans represented 52% of the Company's loan portfolio at March 31, 2015, consistent with December 31, 2014. C&I loans grew $205 million, or 19%, since March 31, 2014. During the 12 months ended March 31, 2015, the Company also grew loans in the Construction real estate, Residential real estate, and Consumer and other categories, with a modest $2.6 million decline in Commercial real estate.
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. Our specialized market segments, particularly life insurance premium finance, and enterprise value lending have contributed to the growth in the C&I category. C&I loan growth also supports our efforts to maintain the Company's asset sensitive interest rate risk position. At March 31, 2015, 63% of our portfolio loans had variable interest rates.
Purchase credit impaired ("PCI") loans and other real estate covered under FDIC loss share agreements
PCI loans totaled $95 million at March 31, 2015, a decrease of $4.3 million, or 4%, from the linked fourth quarter, and $33.9 million, or 26%, from the prior year, primarily as a result of principal paydowns and accelerated loan payoffs.
Other real estate covered under FDIC loss share agreements at March 31, 2015 was $3.6 million, a 40% decrease from $5.9 million at December 31, 2014. During the first quarter of 2015, the Company sold $2.6 million of other real estate, resulting in a negligible net loss.
The Company remeasures contractual and expected cash flows on PCI loans on a periodic basis. When the remeasurement process results in a decrease in expected cash flows due to an increase in expected credit losses, impairment is recorded through the provision for loan losses. Similarly, when expected credit losses decrease in the remeasurement process, prior recorded impairment is reversed before the yield is increased prospectively. Concurrently, the FDIC loss share receivable is adjusted to reflect anticipated future cash to be received from the FDIC. In the first quarter of 2015, reversal of provision for loan losses of $3.3 million was recorded for certain loan pools. The provision benefit was partially offset through noninterest income by a decrease in the FDIC loss share receivable.
Actual cash collections in excess of expected cash flows that represent accelerated loan payoffs result in the recognition of income, but also generally result in a decrease in the FDIC loss share receivable. These cash flows are, by their nature, unpredictable and can vary significantly period to period. Actual cash collections in excess of expected cash flows from loan payoffs and real estate sales in the first quarter resulted in accelerated discount income of $1.9 million, which was partially offset by a decrease in the FDIC loss share receivable.

At March 31, 2015, the remaining accretable yield on the portfolio was estimated to be $33 million and the non-accretable difference was approximately $38 million. Absent cash flow accelerations or pool impairment, the Company currently estimates average PCI loan balances to be approximately $80 million and income before tax expense on PCI assets will be approximately $8 million to $10 million in 2015 inclusive of first quarter 2015.
Asset quality for portfolio loans and other real estate
Nonperforming loans were 0.62% of portfolio loans at March 31, 2015, versus 0.91% of portfolio loans at December 31, 2014, and 0.71% at March 31, 2014. The Company's allowance for loan losses was 1.24% of loans at March 31, 2015, representing 200% of nonperforming loans, as compared to 1.24% at December 31, 2014, representing 136% of nonperforming loans, and 1.28% at March 31, 2014, representing 180% of nonperforming loans.
Nonperforming loans decreased 32% to $15.1 million at March 31, 2015, from $22.2 million at December 31, 2014, and decreased 2% from $15.5 million at March 31, 2014. During the quarter ended March 31, 2015, there were $2.6 million of charge-offs, $13.9 million of other principal reductions, $0.5 million of assets transferred to other real estate, and $9.8 million of additions to nonperforming loans. The additions to nonperforming loans consisted of primarily five unrelated accounts.
Other real estate totaled $2.0 million at March 31, 2015, an increase of $0.1 million from December 31, 2014. At March 31, 2014, other real estate totaled $10.0 million.
Nonperforming assets as a percentage of total assets decreased to 0.52% at March 31, 2015, compared to 0.74% at December 31, 2014 and 0.81% at March 31, 2014.
Net charge-offs in the first quarter of 2015 were $1.5 million, representing an annualized rate of 0.25% of average loans, compared to net charge-offs of $0.6 million in the linked fourth quarter. Net charge-offs were $0.4 million, an annualized rate of 0.08%, in the first quarter of 2014.
The resulting provision for loan losses was $1.6 million in the first quarter of 2015 compared to $2.0 million in the fourth quarter of 2014 and $1.0 million in the first quarter of 2014.

Deposits
Total deposits at March 31, 2015 were $2.7 billion, an increase of $183 million, or 7%, from December 31, 2014, and $223 million, or 9%, from March 31, 2014. The positive trends in deposits reflected seasonal growth as well as enhanced deposit gathering efforts in both commercial and business banking.
Noninterest-bearing deposits increased $38.1 million compared to December 31, 2014 and increased $68.3 million compared to the quarter ended March 31, 2014. The composition of Noninterest-bearing deposits remained stable at 25% of total deposits at March 31, 2015, from March 31, 2014. The total cost of deposits declined 4 basis points since March 31, 2014.
Noninterest income
First quarter 2015 deposit service charges were steady at $1.9 million compared to the linked quarter, and grew 7% compared to the prior year quarter. Additionally, Wealth management revenues were stable at $1.7 million compared to the linked fourth quarter and the prior year period.
Trust assets under management were $894 million at March 31, 2015, an increase of $29 million, or 14% on an annualized basis, when compared to the linked period ended December 31, 2014, and an increase of $13 million, or 2%, when compared to the prior year period. The increase in Trust assets under management as compared to the linked quarter was due to the addition of new clients during the quarter as well as general market appreciation.
Trust assets under administration were $1.5 billion at March 31, 2015, an increase of $38 million, or 11% on an annualized basis, when compared to the linked period ended December 31, 2014, and an increase of $35 million, or 2%, when compared to the prior year period ended March 31, 2014.
Gains from state tax credit brokerage activities, net of fair value market adjustments on tax credit assets and related interest rate hedges, were $0.7 million for the first quarter of 2015, compared to $1.4 million for the linked fourth quarter and $0.5 million in the first quarter of 2014. Sales of state tax credits can vary by quarter, but generally occur in the first and fourth quarters of the year depending on client demand and availability of the tax credits.
Noninterest Expenses
Noninterest expenses were $20.0 million for the quarter ended March 31, 2015, compared to $24.8 million for the quarter ended December 31, 2014 and $21.1 million for the quarter ended March 31, 2014. Core noninterest expenses1, which exclude certain non-comparable items and expenses directly related to PCI loans and assets covered under loss share agreements, decreased to $19.1 million for the quarter ended March 31, 2015, from $20.2 million for the linked quarter and $20.4 million for the prior year period.
The Company's Core efficiency ratio1 was 60.7% for the quarter ended March 31, 2015, compared to 62.8% for the linked quarter, and 68.2% for the prior year period, and reflects lower legal expenses on problem loans, overall expense management and revenue growth trends.
The Company anticipates total noninterest expenses to be between $19 million and $21 million per quarter for 2015.

Other Business Results
The Company adopted the Basel III regulatory capital framework beginning with the first quarter reporting. The total risk based capital ratio1 was 12.84% at March 31, 2015, compared to 13.40% at December 31, 2014, and 13.65% at March 31, 2014. The Company's Common equity tier 1 capital ratio1 was 9.74% at March 31, 2015, compared to 10.15% at December 31, 2014, and 10.22% at March 31, 2014. The tangible common equity ratio1 was 9.01% at March 31, 2015, versus 8.69% at December 31, 2014, and 8.25% at March 31, 2014. The total risk based capital and Common equity tier 1 ratios declined mainly due to the impact of the new regulatory guidelines under Basel III. The increase in the tangible common equity ratio as compared to the prior quarter was due to market gains in the investment portfolio and current year earnings. Capital ratios for the current quarter are based on the Company’s interpretations of the Basel III regulatory capital framework as applied to the Company’s current businesses and operations and are subject to, among other things, completion and filing of the Company’s regulatory reports and ongoing regulatory review and implementation guidance. The attached tables contain a reconciliation of these ratios to U.S. GAAP financial measures.
The Company's effective tax rate was 35.0% for the quarter ended March 31, 2015 compared to 32.0% for the quarter ended December 31, 2014 and 34.0% for the prior year period.
Use of Non-GAAP Financial Measures1
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 Core net income margin and other Core performance measures, tangible common equity ratio and Common equity tier 1 capital 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 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 PCI loans and related income and expenses, the impact of nonrecurring items, and the Company's operating performance on an ongoing basis. Core performance measures include contractual interest on PCI loans but exclude incremental accretion on these loans. Core performance measures also exclude the Change in FDIC receivable, Gain or loss of other real estate covered under FDIC loss share agreements and expenses directly related to the PCI loans and other assets covered under FDIC loss share agreements. Core performance measures also exclude certain other income and expense items 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 and the Common equity tier 1 capital ratios provide useful information to investors about the Company's capital strength even though they are considered to be non-GAAP financial measures and are 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 tables below, 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 measure for the periods indicated.
