Notes to Condensed Consolidated Financial Statements (Unaudited)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by Enterprise Financial Services Corp (the “Company” or “Enterprise”) 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 located in the St. Louis, Kansas City and Phoenix metropolitan markets through its banking subsidiary, Enterprise Bank & Trust (the “Bank”).

Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2014. 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, 2013.

Basis of Financial Statement Presentation

The condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and footnotes required by U.S. GAAP for annual financial statements. 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, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.

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. Common shares outstanding include common stock and restricted stock awards where recipients have satisfied the vesting terms. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method for convertible trust preferred securities.

6

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

	Three months ended June 30,				Six months ended June 30,
(in thousands, except per share data)	2014		2013		2014		2013
Net income as reported	$	7,160	$	11,033	$	13,008	$	21,073

Net income available to common shareholders and assumed conversions	$	7,160	$	11,387	$	13,074	$	21,782
Weighted average common shares outstanding	19,824		18,119		19,673		18,052
Incremental shares from assumed conversions of convertible trust preferred securities	—		1,439		115		1,439

Weighted average diluted common shares outstanding	19,963		19,711		19,956		19,606

Diluted earnings per common share:	$	0.36	$	0.58	$	0.66	$	1.11

For the three months ended June 30, 2014 and 2013, the amount of common stock equivalents that were excluded from the earnings per share calculations because their effect was anti-dilutive was 289,469, and 551,667 common stock equivalents, respectively. For the six months ended June 30, 2014 and 2013, the amount of common stock equivalents that were excluded from the earnings per share calculations because their effect was anti-dilutive was 286,469, and 547,356 common stock equivalents (including 14,324 common stock warrants), respectively.

At June 30, 2014, and December 31, 2013, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than the U.S. government agencies and sponsored enterprises. The residential mortgage-backed securities are all issued by U.S. government sponsored enterprises. Available for sale securities having a fair value of $244.6 million and $270.1 million at June 30, 2014, and December 31, 2013, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions.

The amortized cost and estimated fair value of debt securities classified as available for sale at June 30, 2014, 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 5 years.

(in thousands)	Amortized Cost		Estimated Fair Value
Due in one year or less	$	2,214	$	2,248
Due after one year through five years	108,727		110,065
Due after five years through ten years	22,425		22,767
Due after ten years	8,224		7,824

The unrealized losses at both June 30, 2014, and December 31, 2013, were primarily attributable to changes in market interest rates since the securities were purchased. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. At June 30, 2014, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

The gross gains and gross losses realized from sales of available-for-sale investment securities were as follows:

The Company grants commercial, real estate, and consumer loans primarily in the St. Louis, Kansas City and Phoenix metropolitan areas. 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 is concentrated in and 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 Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, and current economic factors, among other factors. The Company uses the following definitions for risk ratings:

• Grades 1, 2, and 3- These grades include 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- This grade includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow.

• Grade 5- This grade includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow.

• Grade 6- This grade 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 circumstanceswhere 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 - Watch 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 will include those borrowers that are 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.

A summary of activity in the FDIC loss share receivable for the six months ended June 30, 2014 is as follows:

(In thousands)	June 30, 2014
Balance at beginning of period	$	34,319
Adjustments not reflected in income:
Cash received from the FDIC for covered assets	(4,212		)
FDIC reimbursable losses, net	553
Adjustments reflected in income:
Amortization, net	(4,753		)
Loan impairment	2,259
Reductions for payments on covered assets in excess of expected cash flows	(2,658		)
Balance at end of period	$	25,508

Due to continued favorable projections in the expected cash flows, the Company continues to anticipate it will be required to pay the FDIC at the end of two of its loss share agreements. Accordingly, a liability of $1.6 million has been recorded at June 30, 2014. The liability will continue to be adjusted as part of the quarterly remeasurement process through the end of the loss share agreements.

NOTE 6 - COMMITMENTS AND CONTINGENCIES

The Company issues financial instruments with off balance sheet risk in the normal course of the 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 under commitments to extend credit and standby letters of credit in the event of nonperformance by the other party to the financial instrument 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. At June 30, 2014, there were no unadvanced commitments on impaired loans compared to $0.1 million at December 31, 2013. Other liabilities include approximately $0.2 million at both June 30, 2014 and December 31, 2013 for estimated losses attributable to the unadvanced commitments.

The contractual amounts of off-balance-sheet financial instruments as of June 30, 2014, and December 31, 2013, are as follows:

(in thousands)	June 30, 2014		December 31, 2013
Commitments to extend credit	$	836,110	$	804,420
Standby letters of credit	47,304		44,376

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, 2014, and December 31, 2013, approximately $69.3 million and $50.3 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. The type of collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance 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 standby letters of credit is essentially the same as the risk involved in extending loans to customers. The remaining terms of standby letters of credit range from 1 month to 4 years at June 30, 2014.

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 8 - FAIR VALUE MEASUREMENTS

Below is a description of certain assets and liabilities measured at fair value.

The following table summarizes financial instruments measured at fair value on a recurring basis as of June 30, 2014, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value.

Total liabilities	$	—	$	1,184	$	—	$	1,184

• Securities available for sale. Securities classified as available for sale are reported at fair value utilizing Level 2 and Level 3 inputs. The Company obtains fair value measurements from an independent pricing service. Fair values for Level 2 securities are based upon dealer quotes, market spreads, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions at the security level. At June 30, 2014, Level 3 securities available for sale consist primarily of three Auction Rate Securities that are valued based on the securities' estimated cash flows, yields of comparable securities, and live trading levels.

• Portfolio Loans. Certain fixed rate portfolio loans are accounted for as trading instruments and reported at fair value. Fair value on these loans is determined using a third party valuation model with observable Level 2 market data inputs.

• State tax credits held for sale. At June 30, 2014, of the $45.5 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $15.0 million were carried at fair value. The remaining $30.5 million of state tax credits were accounted for at cost.

The Company is not aware of an active market that exists for the 10-year streams of state tax credit financial instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents who buy these credits and from local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine the fair value.

The fair value measurement is calculated using an internal valuation model with observable market data including discounted cash flows based upon the terms and conditions of the tax credits. If the underlying project remains in compliance with the various federal and state rules governing the tax credit program, each project will generate about 10 years of tax credits. The inputs to the discounted cash flow calculation include: the amount of tax credits generated each year, the anticipated sale price of the tax credit, the timing of the sale and a discount rate. The discount rate is estimated using the LIBOR swap curve at a point equal to the remaining

22

life in years of credits plus a 205 basis point spread. With the exception of the discount rate, the other inputs to the fair value calculation are observable and readily available. The discount rate is considered a Level 3 input because it is an “unobservable input” and is based on the Company’s assumptions. An increase in the discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits. Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level 3 assets.

• Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its interest rate swaps and caps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Other liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets in the consolidated balance sheets.

Level 3 financial instruments

The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis for the periods ended June 30, 2014 and 2013, respectively.

• Purchases, sales, issuances and settlements, net. There were no Level 3 purchases during the six months or quarters ended June 30, 2014 or 2013.

• Transfers in and/or out of Level 3. There were no Level 3 transfers during the six months or quarters ended June 30, 2014 or 2013.

From time to time, the Company measures certain assets at fair value on a nonrecurring basis. These include assets that are measured at the lower of cost or fair value that were recognized at fair value below cost at the end of the period. The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring basis as of June 30, 2014:

	(1)		(1)		(1)		(1)
(in thousands)	Total Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total losses for the three months ended June 30, 2014			Total losses for the six months ended June 30, 2014
Impaired loans	$	4,193	$	—	$	—	$	4,193	$	(1,093	)	$	(2,462	)
Other real estate	5,444		—		—		5,444		(246		)	(590		)
Total	$	9,637	$	—	$	—	$	9,637	$	(1,339	)	$	(3,052	)

(1) The amounts represent only balances measured at fair value during the period and still held as of the reporting date.

Impaired loans are reported at the fair value of the underlying collateral or by determining the net present value of future cash flows. Fair values for collateral dependent impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Fair values of impaired loans that are not collateral dependent are determined by using a discounted cash flow model to determine the net present value of future cash flows. Other real estate owned is adjusted to fair value upon foreclosure of the loan collateral. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions.

Following is a summary of the carrying amounts and fair values of the Company’s financial instruments on the consolidated balance sheets at June 30, 2014, and December 31, 2013.

NOTE 9 - SEGMENT REPORTING

The Company has two primary operating segments, Banking and Wealth Management, which are delineated by the products and services that each segment offers. The segments are evaluated separately on their individual performance, as well as their contribution to the Company as a whole.

The Banking operating segment consists of a full-service commercial bank, with locations in St. Louis, Kansas City, and Phoenix. The majority of the Company’s assets and income result from the Banking segment. All banking locations have the same product and service offerings, have similar types and classes of customers and utilize similar service delivery methods. Pricing guidelines and operating policies for products and services are the same across all regions.

The Banking operating segment also includes activities surrounding PCI loans and other assets acquired under FDIC loss share agreements. 

The Wealth Management operating segment includes the Trust division of the Bank and the state tax credit brokerage activities. The Trust division provides estate planning, investment management, and retirement planning as well as strategic planning and management succession issues. State tax credits are part of a fee initiative designed to augment the Company’s Wealth Management segment and Banking lines of business.

26

The Company's Corporate and Intercompany activities represent the elimination of items between segments as well as Corporate related items that management feels are not allocable to either of the two respective segments.

The financial information for each business segment reflects that information which is specifically identifiable or which is allocated based on an internal allocation method. There were no material intersegment revenues among the two segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. When appropriate, these changes are reflected in prior year information presented below.

Following are the financial results for the Company’s operating segments.

NOTE 10 - NEW AUTHORITATIVE ACCOUNTING GUIDANCE

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, (“ASU 2014-09”), “Revenue from Contracts with Customers”. The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle of ASU 2014-09 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the new guidance, an entity will (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the contract’s performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification. The new guidance is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 for public companies. Early adoption is not permitted. Entities have the option of using either a full retrospective or modified approach to adopt ASU 2014-09. The Company is currently evaluating the new guidance and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption.

During the quarter ended June 30, 2014 the Company noted the following :

• The Company reported net income of $7.2 million for the three months ended June 30, 2014, compared to $5.8 million in the linked first quarter, and $11.0 million for the same period in 2013. The Company reported diluted earnings per share of $0.36, $0.30 and $0.58 in the same respective periods. The increase in net income from the linked first quarter is primarily due to impairment reversal on our provision for loan losses for PCI

30

loans as well as reduced noninterest expenses in the current period as the company incurred lower loan legal and other real estate expenses, as well as lower professional fees. The decrease in net income from the prior year period is primarily due to a $6.6 million overall benefit in provision for loan losses recorded from improved credit quality on our portfolio loans over prior year periods as well as impairment reversal on our PCI loans.

• Net interest income decreased $1.6 million in the second quarter of 2014 from the linked first quarter and $4.6 million from the prior year period, primarily due to lower balances on PCI loans and lower interest rates on newly originated loans. The decrease was partially offset by strong portfolio loan growth in the quarter as core net interest income increased modestly in the second quarter.

• Nonperforming loans were 0.86% of portfolio loans at June 30, 2014, versus 0.71% of portfolio loans at March 31, 2014, and 1.25% at June 30, 2013. The Company's allowance for loan losses was 1.26% of loans at June 30, 2014, representing 147% of nonperforming loans, as compared to 1.28% at March 31, 2014 representing 131% of nonperforming loans, and 1.33% at June 30, 2013, representing 106% of nonperforming loans. Net charge-offs in the second quarter of 2014 were $0.8 million, representing an annualized rate of 0.15% of average loans, compared to net charge-offs of $0.4 million, an annualized rate of 0.08%, in the linked first quarter. Net charge-offs were $0.5 million, an annualized rate of 0.10%, in the second quarter of 2013.

• Fee income which primarily includes the Company's wealth management revenue, service charges and other fees on deposit accounts, sales of other real estate, and state tax brokerage activity was relatively stable compared to the linked quarter and increased $0.5 million from the prior year period. The increase from the prior year period was primarily due to a $0.4 million increase in gains on the sale of other real estate as well as $0.2 million increase in gains on state tax credits.

• Noninterest expenses were $20.4 million for the quarter ended June 30, 2014, compared to $21.1 million for both the linked quarter ended March 31, 2014 and prior year period ended June 30, 2013. Noninterest expenses have decreased when compared to both periods. The decrease from the linked quarter is primarily due to reduced employee compensation and benefit costs as well as lower professional fees. The decrease in noninterest expenses over the prior year period was primarily due to lower loan, legal and other real estate expenses from improved credit quality.

For the six month period ended June 30, 2014 the Company noted the following :

• The Company reported net income of $13.0 million for the six months ended June 30, 2014, compared to $21.1 million for the same period in 2013. The Company reported diluted earnings per share of $0.66 and $1.11 in the same respective periods. The decrease in net income for the current year to date is due to the factors noted above as well as reduced revenue from our PCI loans, lower interest yields on our portfolio loans offsetting volume gains, as well as lower investment security gains.

• Net interest income decreased $11.1 million in the six month period of 2014 from the comparable period in 2013. The decrease was due to lower balances and lower accelerated payments on PCI loans, lower prepayment fees on portfolio loans, and lower interest rates on newly originated loans. These items were offset by higher balances of portfolio loans and lower interest expense from the conversion of $25.0 million of trust preferred securities to common equity and early payoff of $30.0 million of FHLB borrowings, both of which carried relatively higher interest rates.

Income Before Income Tax Expense

Income before income tax expense on the Company's Core Bank and Covered assets for the three and six months ended June 30, 2014 and 2013 were as follows:

31

(In thousands)	Three months ended June 30,				Six months ended June 30,
	2014		2013		2014		2013
Income before income tax expense
Core Bank	$	7,840	$	12,741	$	14,753	$	20,691
Covered assets	2,984		4,316		4,926		11,785
Total	$	10,824	$	17,057	$	19,679	$	32,476

Income before income tax expense for the Core Bank represents results without direct income and expenses related to Covered assets, as well as an internal estimate of associated asset funding costs for those covered assets. Core Bank pre-tax income declined $4.9 million, or 38%, in the quarter as the Company recorded a benefit in provision for portfolio loan losses of $4.3 million in the prior year period compared to $1.3 million of provision expense in the current year quarter. Income from our Covered assets declined $1.3 million, or 31%, from declining balances in our PCI loans, reduced impairment reversal reflected in provision for loan losses, as well as reduced net interest income primarily from a reduction in accelerated cash flows.

Core Bank pre-tax income declined $5.9 million, or 29%, in the six month period ended June 30, 2014 as compared to the prior year period as the Company recorded a benefit in provision for portfolio loan losses of $2.4 million in the prior year period and the Company's interest income was reduced from lower loan yields on originations. Income from our Covered assets declined $6.9 million, or 58%, from declining balances in our PCI loans, overall impairment reversal reflected in provision for loan losses in the prior year period, as well as reduced net interest income primarily from a reduction in accelerated cash flows.

The Core net interest margin, defined as the Net interest margin (fully tax equivalent), including contractual interest on Covered loans, but excluding the incremental accretion on these loans, for the three and six months ended June 30, 2014 and 2013 is as follows:

	Three months ended June 30,				Six months ended June 30,
	2014		2013		2014		2013
Core net interest margin	3.39	%	3.56	%	3.42	%	3.55	%

The Core net interest margin has declined in both the three and six months ended June 30, 2014. The decline was due to lower loan yields from lower prepayment fees, lower balances of PCI loans which have higher contractual interest rates, as well as originations at lower interest rates. This was partially offset by lower costs of interest bearing liabilities including lower deposit costs and lower cost of borrowings from the aforementioned FHLB prepayment and conversion of $25.0 million, 9% coupon, trust preferred securities into common stock. Pressure on loan yields continue to lead to reductions in the core net interest margin and could lead to further reductions throughout the remainder of 2014. Included in this MD&A under the caption "Use of Non-GAAP Financial Measures" is a reconciliation of net interest margin to Core net interest margin. The Average Balance Sheet and Rate/Volume sections following contain additional information regarding our net interest income.

2014 Significant Transactions

During 2014, we completed the following significant transaction:

• On March 14, 2014 the remaining $5.0 million, 9% coupon, trust preferred securities were converted to shares of common stock. As a result of this transaction, the Company reduced its long-term debt by $5.0 million and issued 287,852 shares of common stock.

(1) Change in volume multiplied by yield/rate of prior period.

(2) Change in yield/rate multiplied by volume of prior period.

(3) Nontaxable income is presented on a fully tax-equivalent basis using the combined statutory federal and state income tax rate in effect for each year.

NOTE: The change in interest due to both rate and volume has been allocated to rate and volume changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Net interest income (on a tax equivalent basis) was $29.1 million for the three months ended June 30, 2014 compared to $33.8 million for the same period of 2013, a decrease of $4.7 million, or 14%. Total interest income decreased $5.9 million and total interest expense decreased $1.2 million. The tax-equivalent net interest rate margin was 4.03% for the second quarter of 2014, compared to 4.39% for the first quarter of 2014 and 4.75% in the second quarter of 2013.

Net interest income (on a tax equivalent basis) was $59.9 million for the six months ended June 30, 2014, compared to $71.3 million for the same period of 2013, a decrease of $11.3 million, or 16%. Total interest income decreased $13.9 million and total interest expense decreased $2.5 million. The tax-equivalent net interest rate margin was 4.21% for the six months ended 2014, compared to 4.93% in the six months ended June 30, 2013.

35

Interest rates remain at historically low levels and continue to negatively impact loan yields leading to lower net interest margins. As seen in the table above, changes in interest rates have led to a $2.4 million and $4.8 million reduction in interest income on our portfolio loans for the three and six months ended June 30, 2014 and a $2.1 million and $4.3 million reduction in interest income on our PCI loans for the same periods. Additionally, the run-off of higher yielding PCI loans continue to negatively impact net interest margin leading to a $2.9 million and $6.7 million decrease in interest income due to volume for the quarter and six months ended June 30, 2014. To partially mitigate lower yields on loans the Company has taken specific actions to lower deposit and other borrowing costs including the prepayment of $30.0 million of FHLB borrowings with a weighted average interest rate of 4.09%, the conversion of $25.0 million of 9% coupon, trust preferred securities to common stock, and the prepayment of $3.6 million of the Company's term loan to lower the contractual interest rate by 50 basis points. Additionally portfolio loan growth of $114 million since December 31, 2013 has resulted in interest income growth of $1.4 million and $1.8 million for the three and six months ended June 30, 2014.

The following table illustrates the net revenue contribution of PCI loans and other assets covered under FDIC shared loss agreements for the most recent five quarters. The presentation excludes the cost of funding the related assets and the operating expenses to service the assets.

36

Noninterest income increased $5.1 million, in the second quarter of 2014 compared to the second quarter of 2013. The increase is primarily due to a $4.0 million increase in the change in FDIC loss share receivable from higher accelerated cash flows in the prior period, as well as $0.6 million increase in miscellaneous income due to higher income on our bank owned life insurance ("BOLI") from a $20.0 million policy entered into late in the second quarter of 2013, as well as higher income from the sale of mortgages.

Total noninterest income	$	7,327		$	1,237		$	6,090		492	%

Noninterest income increased $6.1 million, or 492%, in the six months ended June 30, 2014 compared to the same period of 2013. The increase is primarily due to a $5.6 million increase in the change in FDIC loss share receivable from higher accelerated cash flows in the prior period, as well as $1.0 million increase in Miscellaneous income from higher income on the $20.0 million BOLI policy entered into late in the second quarter of 2013.

Noninterest Expense

The following table presents a comparative summary of the major components of noninterest expense:

	Three months ended June 30,
(in thousands)	2014		2013		Increase (decrease)
Employee compensation and benefits	$	11,853	$	10,766	$	1,087		10	%
Occupancy	1,675		1,693		(18		)	(1	)%
Data processing	1,125		936		189			20	%
FDIC and other insurance	761		833		(72		)	(9	)%
Loan legal and other real estate expense	1,040		2,075		(1,035		)	(50	)%
Professional fees	592		928		(336		)	(36	)%
Other	3,399		3,916		(517		)	(13	)%
Total noninterest expense	$	20,445	$	21,147	$	(702	)	(3	)%

Noninterest expenses were $20.4 million in the second quarter of 2014, a decrease of $0.7 million, from the same quarter of 2013. The decrease over the prior year period is primarily due to a decrease in loan legal and other real estate expenses from improved credit quality. Reduced professional fees $0.3 million from lower legal expenses and other expenses of $0.5 million primarily due to $0.4 million less recorded expense for expected payments to the FDIC associated with our loss share agreements also reduced noninterest expenses. These expense reductions were offset by an increase in employee compensation and benefits costs of $1.1 million due to insourcing our risk management functions, as well as higher employee benefit costs.

The Company's efficiency ratio, which measures noninterest expense as a percentage of total revenue, was 63.6% for the quarter ended June 30, 2014 compared to 66.9% for the prior year period. The Company expects noninterest expenses to remain between $20 million and $22 million per quarter in 2014.

Total noninterest expense	$	41,547	$	41,432	$	115		—	%

Noninterest expenses have increased $0.1 million in the six month period ended June 30, 2014 as compared to the same period of 2013. The increase is due to a $1.7 million increase in employee compensation and benefits costs for similar reasons noted above, offset by $0.5 million reduction in professional fees from lower legal expenses, as well as a reduction in other expenses of $1.1 million primarily due to $0.7 million less recorded expense for expected payments to the FDIC associated with our loss share agreements.

The Company's efficiency ratio, which measures noninterest expense as a percentage of total revenue, was 62.5% for the six months ended June 30, 2014 compared to 58.0% for the prior year period.

Income Taxes

For the quarter ended June 30, 2014, the Company’s income tax expense, which includes both federal and state taxes, was $3.7 million compared to $6.0 million for the same period in 2013. The combined federal and state effective income tax rate was 33.9% for the quarter ended June 30, 2014, slightly lower than June 30, 2013, due to lower state taxes.

For the six months ended June 30, 2014, the Company’s income tax expense, which includes both federal and state taxes, was $6.7 million compared to $11.4 million for the same period in 2013. The combined federal and state effective income tax rate was 33.9% for the six month period ended June 30, 2014, slightly lower than the comparable period ended June 30, 2013 also due to lower state taxes.

Assets

Loans by Type

The Company grants commercial, residential, and consumer loans primarily in the St. Louis, Kansas City and Phoenix metropolitan areas. 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 is concentrated in and 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 summarizes the composition of the Company's loan portfolio:

(in thousands)	June 30, 2014		December 31, 2013		Increase (decrease)
Commercial and industrial	$	1,135,069	$	1,041,576	$	93,493		9.0	%

Total loans	$	2,369,606	$	2,277,851	$	91,755		4.0	%

Portfolio loans totaled $2.3 billion at June 30, 2014, increasing $114 million, compared to December 31, 2013 as the Company experienced continued growth in its Commercial and Industrial ("C&I") loans, as well as our Owner Occupied Commercial real estate loans. PCI loans totaled $119 million at June 30, 2014, a decrease of $22.0 million, or 16% from December 31, 2013, primarily as a result of principal paydowns and accelerated loan payoffs.

The provision for loan losses on portfolio loans for the threemonths ended June 30, 2014 was $1.3 million compared to a $4.3 million benefit for the comparable 2013 period. For the six month period ended June 30, 2014 provision for loan losses on portfolio loans was $2.4 million compared to a $2.4 million benefit in the prior year period. The provision for loan loss in the second quarter and for the year to date period ended June 30, 2014 was primarily to provide for charge-offs incurred. The benefit in loan provision for the second quarter and year to date period ended June 30, 2013 was primarily due to significant improvements in credit quality seen in the prior year including improvement in loan risk ratings and loss migration results, as well as lower levels of classified loans.

For PCI loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the remeasurement process results in a decrease in expected cash flows, typically due to an increase in expected credit losses, impairment is recorded through 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. The provision for loan losses on PCI loans for the three months ended June 30, 2014 was a reversal of $0.5 million compared to a reversal of $2.3 million for the comparable 2013 periods. The provision for loan losses on PCI loans for the six months ended June 30, 2014 was $2.8 million compared to a reversal of $22,000 for the comparable 2013 periods.

The allowance for loan losses on portfolio loans was 1.26% of total loans at June 30, 2014, compared to 1.28% at March 31, 2014, and 1.33% at June 30, 2013. Management believes that the allowance for loan losses is adequate to absorb inherent losses in the loan portfolio. The reduction in the ratio of allowance for loan losses to total loans over the linked quarter and prior year period is due to continued strong credit performance, as well as continued improvement in our loss migration results.

Nonperforming loans

Nonperforming loans exclude PCI loans that are accounted for on a pool basis, as the pools are considered to be performing. See Note 5 – Purchase Credit Impaired ("PCI") Loans for more information on these loans.

Nonperforming loans at June 30, 2014 were $19.3 million, an increase from $15.5 million at March 31, 2014, and a decrease from $25.9 million at June 30, 2013. The additions to nonperforming loans were comprised of four relationships, and all were deemed by management to be well secured at June 30, 2014. The nonperforming loans are comprised of approximately 19 relationships, with the largest from a $4.6 million Commercial Real Estate loan. The top five relationships comprise 60% of the nonperforming loans. Approximately 56% of nonperforming loans were located in the St. Louis market, 30% were located in the Kansas City market, and 14% were located in the Arizona market. At June 30, 2014, there were 3 performing restructured loans in the amount of $2.8 million that have been excluded from the nonperforming loan amounts.

Nonperforming loans represented 0.86% of portfolio loans at June 30, 2014, versus 0.71% at March 31, 2014 and 1.25% at June 30, 2013.

At June 30, 2014, other real estate was comprised of 30 properties, with the largest being a $2.9 million commercial property in the Kansas City region.

43

Writedowns in fair value were recorded in Loan legal and other real estate expense or are charged-off existing loan balances based on current market activity shown in the appraisals. In addition, for the three and six months ended June 30, 2014, the Company realized a net gain of $0.7 million and $1.4 million, respectively, on the sale of other real estate, as compared to $0.4 million and $1.1 million in the prior year period. Gains on the sale of other real estate are recorded as part of Noninterest income.

Liabilities

Liabilities totaled $2.9 billion at June 30, 2014, consistent with amounts recorded at December 31, 2013. Liabilities remained stable due to a $69.5 million decrease in total deposits, as well as $37.9 million decrease in other borrowings primarily due to a decrease in securities sold under repurchase agreements, offset by an increase of $104 million in short-term Federal Home Loan Bank advances.

Total deposits at June 30, 2014 were $2.5 billion, a decrease of $69.5 million, or 3%, from December 31, 2014. The decrease in deposits from year-end was primarily in our money market accounts and certificates of deposits primarily resulting from seasonality. The composition of our noninterest bearing deposits increased to 27% of total deposits at June 30, 2014 compared to 26% at December 31, 2014, although a portion of the increase in demand deposits represented temporary client moves from interest bearing deposit accounts. During the quarter ending June 30, 2014, our cost of deposits was slightly lower compared to the linked first quarter at 0.43% as compared to 0.44%, and improved from the 0.47% for the prior year period.

Shareholders' Equity

Shareholders' Equity totaled $302 million at June 30, 2014, an increase of $21.9 million from December 31, 2013. Significant activity during the six months ended June 30, 2014 included:

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 run-off from demand deposits, maturing time deposits which are not renewed, and fundings under credit commitments to customers. Funds are available from a number of sources, such as from the core deposit base and from loans and securities repayments and maturities.

Additionally, liquidity is provided from sales of the securities portfolio, Fed fund lines with correspondent banks, the Federal Reserve Bank and the FHLB, the ability to acquire large and brokered deposits, and the ability to sell 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 Bank'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 monthly by producing a liquidity report, which measures the amount of liquid versus non-liquid assets and liabilities. Ourliquidity 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 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.

Parent Company liquidity

The parent company's liquidity is managed to provide the funds necessary to pay dividends to shareholders, service debt, invest in subsidiaries as necessary, and satisfy other operating requirements. The parent company's primary funding sources to meet its liquidity requirements are dividends and payments from the Bank and proceeds from the issuance of equity (i.e. stock option exercises, stock offerings). Another source of funding for the parent company includes the issuance of subordinated debentures. Management believes our current level of cash at the holding company of approximately $7.7 million will be sufficient to meet all projected cash needs for at least the next year.

On September 16, 2011, the Company filed a shelf registration statement on Form S-3 registering up to $40.0 million of common stock, preferred stock, debt securities, and various other securities, including combinations of such securities. The registration statement became effective on September 29, 2011. 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 Securities and Exchange Commission.

On November 6, 2012, the parent company entered into a $12.0 million unsecured term loan agreement ("Term Loan") with another bank with proceeds used to redeem the Company's preferred stock held by the U.S. Treasury. The loan has a maturity date of November 6, 2015 and will be repaid in quarterly installments of $300,000, with a balloon payment at maturity. The outstanding balance under the Term Loan was $6.3 million and $10.5 million at June 30, 2014, and December 31, 2013, respectively. The Term Loan pays interest based on LIBOR plus a spread determined by the Company's outstanding balance under the Term Loan agreement. In the first quarter of 2014, the Company prepaid $3.6 million to reduce the interest rate by 50 basis points. The Term Loan is subject to ongoing compliance with a number of customary affirmative and negative covenants as well as specified financial covenants. The Company was in compliance in all material respects with all relevant covenants under the Term Loan at June 30, 2014.

45

As of June 30, 2014, the Company had $56.8 million of outstanding subordinated debentures as part of eight trust preferred securities pools. On March 14, 2014, the Company converted the remaining $5.0 million, 9% coupon, trust preferred securities to shares of common stock. As a result of this transaction the Company reduced its long-term debt by $5.0 million and issued 287,852 shares of common stock. The trust preferred securities are classified as debt but are currently included in regulatory capital and the related interest expense is tax-deductible. Regulations recently finalized by the Federal Reserve Board to implement the Basel III regulatory capital reforms allow our currently outstanding trust preferred securities to retain their Tier 1 capital status.

On January 9, 2013, the Company repurchased warrants issued by the U.S. Treasury as part of the Capital Purchase Program. The repurchase price was approximately $1.0 million.

Bank liquidity

The Bank has a variety of funding sources available to increase financial flexibility. In addition to amounts currently borrowed, at June 30, 2014, the Bank could borrow an additional $180 million from the FHLB of Des Moines under blanket loan pledges and has an additional $667 million available from the Federal Reserve Bank under a pledged loan agreement. The Bank has unsecured federal funds lines with four correspondent banks totaling $45.0 million.

Of the $448 million of the securities available for sale at June 30, 2014, $245 million was pledged as collateral for deposits of public institutions, treasury, loan notes, and other requirements. The remaining $203 million could be pledged or sold to enhance liquidity, if necessary.

The Bank belongs to the Certificate of Deposit Account Registry Service, or CDARS, which allows us to provide our customers with access to additional levels of FDIC insurance coverage on their deposits. The Company considers the reciprocal deposits placed through the CDARS program as core funding and does not report the balances as brokered sources in its internal or external financial reports. As of June 30, 2014, the Bank had $40.2 million of reciprocal CDARS money market sweep balances and $8.1 million of reciprocal certificates of deposits outstanding. In addition to the reciprocal deposits available through CDARS, the Company has access to the “one-way buy” program, which allows the Company to bid on the excess deposits of other CDARS member banks. The Company will report any outstanding “one-way buy” funds as brokered funds in its internal and external financial reports. At June 30, 2014, we had no outstanding “one-way buy” deposits. In addition, the Bank has the ability to sell certificates of deposit through various national or regional brokerage firms, if needed.

In the normal course of business, the Bank enters into certain forms of off-balance sheet transactions, including unfunded loan commitments and letters of credit. These transactions are managed through the Bank'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 Bank has $883 million in unused commitments as of June 30, 2014. The nature of these commitments is such that the likelihood of funding them in the aggregate at any one time is low.

Capital Resources

The Company and the Bank are subject to various regulatory capital requirements administered by the 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 Bank’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 and 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

46

total risk-based (10%), Tier 1 risk-based (6%) and Tier 1 leverage ratios (5%). As of June 30, 2014, and December 31, 2013, the Company and the Bank met all capital adequacy requirements to which they are subject.

The Company continues to exceed regulatory standards and met the definition of “well-capitalized” (the highest category) at June 30, 2014, and December 31, 2013.

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

(Dollars in thousands)	June 30, 2014			December 31, 2013
Tier 1 capital to risk weighted assets	12.38		%	12.52		%
Total capital to risk weighted assets	13.63		%	13.78		%
Tier 1 common equity to risk weighted assets	10.25		%	10.08		%
Leverage ratio (Tier 1 capital to average assets)	10.38		%	9.94		%
Tangible common equity to tangible assets	8.49		%	7.78		%
Tier 1 capital	$	321,040		$	308,490
Total risk-based capital	$	353,558		$	339,433

Use of Non-GAAP Financial Measures:

The Company's accounting and reporting policies conform to generally accepted accounting principles ("GAAP") in the U.S. and the prevailing practices in the banking industry. However, the Company provides other financial measures, such as Core net interest margin, tangible common equity ratio and Tier 1 common equity ratio, in this filing 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 U.S. GAAP.

The Company believes these non-GAAP financial measures and ratios, when taken together with the corresponding U.S. GAAP measures and ratios, provide meaningful supplemental information regarding the Company's performance and capital strength. The Company's management uses, and believes investors benefit from referring to, these non-GAAP measures and ratios in assessing the Company's financial and operating results and related trends and when planning and 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 U.S. GAAP. 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.

The Company believes the tangible common equity and Tier 1 common equity ratios are important financial measures of capital strength even though they are considered to be non-GAAP measures and provide useful information about the Company's capital adequacy. The tables below contain reconciliations of these ratios to the most comparable measure under U.S. GAAP.

The Company believes Core net interest margin is an important measure of our financial performance, even though it is a non-GAAP financial measure, because it provides supplemental information by which to evaluate the impact of excess Covered loan accretion on the Company's net interest margin and the Company's operating performance on an ongoing basis, excluding such impact. The table below reconciles Core net interest margin to the most comparable number under U.S. GAAP.

Net Interest Margin to Core Net Interest Margin

(In thousands)	Three months ended June 30,						Six months ended June 30,
	2014			2013			2014			2013
Net interest income (fully tax equivalent)	$	29,133		$	33,841		$	59,936		$	71,263
Incremental accretion income	(4,539		)	(8,491		)	(11,203		)	(19,854		)
Core net interest income	$	24,594		$	25,350		$	48,733		$	51,409
Average earning assets	$	2,895,982		$	2,858,701		$	2,872,380		$	2,917,054
Reported net interest margin	4.04		%	4.75		%	4.21		%	4.93		%
Core net interest margin	3.39		%	3.56		%	3.42		%	3.55		%

Critical Accounting Policies

The impact and any associated risks related to the Company’s critical accounting policies on business operations are described 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 description 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, 2013.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The disclosures set forth in this item are qualified by the section captioned “Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995” included in Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report and other cautionary statements set forth elsewhere in this report.

Interest Rate Risk

Our interest rate sensitivity management seeks to avoid fluctuating interest margins to provide for consistent growth of net interest income through periods of changing interest rates. 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 minimize or eliminate any impact from market interest rate changes. In order to measure earnings sensitivity to changing rates, the Company uses an earnings simulation model.

The Company determines the sensitivity of its short-term future earnings to a hypothetical plus or minus 100 to 400 basis point parallel rate shock through the use of simulation modeling. The simulation of earnings 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 based on a hypothetical change in interest rates. The resulting net interest income for the next 12-month period is compared to the net interest income amount calculated using flat rates. This difference represents the Company's earnings sensitivity to a plus or minus 100 basis points parallel rate shock.

49

The following table summarizes the expected impact of interest rate shocks on net interest income (due to the current level of interest rates, the 200 and 300 basis point downward shock scenarios are not shown):

Rate Shock	Annual % change in net interest income
+ 300 bp	9.4%
+ 200 bp	6.0%
+ 100 bp	2.5%
- 100 bp	(0.9)%

Interest rate simulations for June 30, 2014, demonstrate that a rising rate environment will have a positive impact on net interest income.

The Company occasionally uses interest rate derivative financial instruments as an asset/liability management tool to hedge mismatches in interest rate exposure indicated by the net interest income simulation described above. At June 30, 2014, the Company had $23.8 million in notional amount of outstanding interest rate caps, to help manage interest rate risk. Derivative financial instruments are also discussed in Part I, Item 1, Note 7 - Derivative Financial Instruments.

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 June 30, 2014. 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 that the Company’s disclosure controls and procedures were effective as of June 30, 2014 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.

ENTERPRISE FINANCIAL SERVICES CORP

CERTIFICATE OF AMENDMENT

OF

CERTIFICATE OF INCORPORATION

Enterprise Financial Services Corp, a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware (the “Corporation”), does hereby certify that the following amendment to the Certificate of Incorporation of said Corporation has been duly adopted in accordance with the provisions of Section 242 of the General Corporation Law of the State of Delaware:

Article FOUR of the Certificate of Incorporation of the Corporation is amended to read in its entirety as follows:

“The aggregate number of shares of all classes of capital stock which the corporation shall have the authority to issue shall be Thirty-five million (35,000,000) shares divided into two classes as follows:

(a) Five million (5,000,000) shares of preferred stock having par value of $.01 per share (the “Preferred Stock”); and

(b) Thirty million (30,000,000) shares of common stock having par value of $.01 per share (the “Common Stock”).

The Board of Directors of the corporation shall be authorized, subject to any limitations prescribed by the law of the State of Delaware, to provide in a resolution or resolutions for the issuance of shares of the Preferred Stock in one or more series, and, by filing a Certificate of Designation pursuant to the applicable law of the State of Delaware (a “Preferred Stock Designation”), to establish from time to time the number of shares to be included in each such series and to fix the designations, powers, preferences and relative, participating, optional or other rights, if any, and the qualifications, limitations or restrictions thereof, if any. The authority of the Board of Directors of the corporation with respect to each series of the Preferred Stock shall include, but not be limited to, determination of the following:

(A) the number of shares constituting that class or series and the distinctive designation of that series;

(B) the dividend rate on the shares of that series, whether dividends shall be cumulative, and, if so, from which date or dates, and the relative rights of priority, if any, of payment of dividends on shares of that series;

(C) whether that series shall have voting rights, in addition to the voting rights provided by law, and, if so, the terms and conditions of such voting rights, including, without limitation, whether such series shall have the right to vote as a separate class and/or vote on a cumulative or noncumulative basis;

(D) whether that series shall have conversion privileges, and, if so, the terms and conditions of such conversion including provision for adjustment of the conversion rate upon the occurrence of such events as the Board of Directors of the corporation shall determine;

(E) whether the shares of that series shall be redeemable, and, if so, the terms and conditions of such redemption, including the date or dates upon or after which they shall be redeemable, and the amount per share payable in case of redemption, which amount may vary under different conditions and at different redemption dates;

(F) whether that series shall have a sinking fund for the redemption or purchase of shares of the series, and, if so, the terms and amount of such sinking fund;

(G) the rights and/or preferences of the shares of that series in the event of the voluntary or involuntary liquidation, dissolution or winding up of the corporation, and the relative rights of priority, if any, of payment in respect of shares of that series; and

(H) any other relative rights, preferences and limitations of that series.

The Board of Directors of the corporation is expressly authorized to adopt such resolution or resolutions and issue such Preferred Stock from time to time as it may deem desirable. The Board of Directors of the corporation is further expressly authorized to increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares of any such series then outstanding) the number of shares of any series of Preferred Stock, the number of which is fixed by it, subsequent to the issuance of shares then outstanding, subject to the powers, preferences and rights, and the qualifications, limitations and restrictions thereof stated in this Certificate of Incorporation or the resolution or resolutions of the Board of Directors of the corporation originally fixing the number of shares of such series. If the number of shares of any series of Preferred Stock is so decreased, then the shares constituting such decrease shall resume the status which they had prior to the adoption of the resolution or resolutions originally fixing the number of shares of such series of Preferred Stock. The number of authorized shares of Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares of such class then outstanding) by the vote of a majority of the outstanding shares of stock entitled to vote thereon, and no separate class vote of either the Common Stock or the Preferred Stock shall be required to effect any such amendment.

The shares of the authorized Common Stock shall be identical in all respects and shall have equal rights and privileges, subject only to the senior rights applicable to the Preferred Stock or any series thereof. Except as may be provided in this Certificate of Incorporation or in a Preferred Stock Designation or by applicable law of the State of Delaware, holders of the Preferred Stock shall not be entitled to receive notice of any meeting of stockholders at which they are not entitled to vote, holders of the Common Stock shall have the exclusive right to vote for the election of Directors of the corporation and for all other purposes, and holders of shares of the Common Stock shall be entitled to one vote for each such share upon all questions presented to the stockholders of the corporation. Holders of the Common Stock shall not have the right to cumulate votes in the election of Directors of the corporation. Holders of shares of the Common Stock shall at all times, except as otherwise provided in this Certificate of Incorporation or as required by the law of the State of Delaware, vote as one class, together with the holders of any other class or series of stock of the Corporation accorded such general voting rights.”

IN WITNESS WHEREOF, the Corporation has caused this Certificate of Amendment to be executed by its duly authorized officer, on this 22nd day of May, 2014.

FAIR VALUE MEASUREMENTS

Below is a description of certain assets and liabilities measured at fair value.

The following table summarizes financial instruments measured at fair value on a recurring basis as of June 30, 2014, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value.

• Securities available for sale. Securities classified as available for sale are reported at fair value utilizing Level 2 and Level 3 inputs. The Company obtains fair value measurements from an independent pricing service. Fair values for Level 2 securities are based upon dealer quotes, market spreads, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions at the security level. At June 30, 2014, Level 3 securities available for sale consist primarily of three Auction Rate Securities that are valued based on the securities' estimated cash flows, yields of comparable securities, and live trading levels.

• Portfolio Loans. Certain fixed rate portfolio loans are accounted for as trading instruments and reported at fair value. Fair value on these loans is determined using a third party valuation model with observable Level 2 market data inputs.

• State tax credits held for sale. At June 30, 2014, of the $45.5 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $15.0 million were carried at fair value. The remaining $30.5 million of state tax credits were accounted for at cost.

The Company is not aware of an active market that exists for the 10-year streams of state tax credit financial instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents who buy these credits and from local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine the fair value.

The fair value measurement is calculated using an internal valuation model with observable market data including discounted cash flows based upon the terms and conditions of the tax credits. If the underlying project remains in compliance with the various federal and state rules governing the tax credit program, each project will generate about 10 years of tax credits. The inputs to the discounted cash flow calculation include: the amount of tax credits generated each year, the anticipated sale price of the tax credit, the timing of the sale and a discount rate. The discount rate is estimated using the LIBOR swap curve at a point equal to the remaining life in years of credits plus a 205 basis point spread. With the exception of the discount rate, the other inputs to the fair value calculation are observable and readily available. The discount rate is considered a Level 3 input because it is an “unobservable input” and is based on the Company’s assumptions. An increase in the discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits. Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level 3 assets.

• Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its interest rate swaps and caps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Other liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets in the consolidated balance sheets.

Level 3 financial instruments

The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis for the periods ended June 30, 2014 and 2013, respectively.

• Purchases, sales, issuances and settlements, net. There were no Level 3 purchases during the six months or quarters ended June 30, 2014 or 2013.

• Transfers in and/or out of Level 3. There were no Level 3 transfers during the six months or quarters ended June 30, 2014 or 2013.

From time to time, the Company measures certain assets at fair value on a nonrecurring basis. These include assets that are measured at the lower of cost or fair value that were recognized at fair value below cost at the end of the period. The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring basis as of June 30, 2014:

	(1)		(1)		(1)		(1)
(in thousands)	Total Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total losses for the three months ended June 30, 2014			Total losses for the six months ended June 30, 2014

Total	$	9,637	$	—	$	—	$	9,637	$	(1,339	)	$	(3,052	)

(1) The amounts represent only balances measured at fair value during the period and still held as of the reporting date.

Impaired loans are reported at the fair value of the underlying collateral or by determining the net present value of future cash flows. Fair values for collateral dependent impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Fair values of impaired loans that are not collateral dependent are determined by using a discounted cash flow model to determine the net present value of future cash flows. Other real estate owned is adjusted to fair value upon foreclosure of the loan collateral. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions.

Following is a summary of the carrying amounts and fair values of the Company’s financial instruments on the consolidated balance sheets at June 30, 2014, and December 31, 2013.

Segment Reporting [Abstract]

Segment Reporting

SEGMENT REPORTING

The Company has two primary operating segments, Banking and Wealth Management, which are delineated by the products and services that each segment offers. The segments are evaluated separately on their individual performance, as well as their contribution to the Company as a whole.

The Banking operating segment consists of a full-service commercial bank, with locations in St. Louis, Kansas City, and Phoenix. The majority of the Company’s assets and income result from the Banking segment. All banking locations have the same product and service offerings, have similar types and classes of customers and utilize similar service delivery methods. Pricing guidelines and operating policies for products and services are the same across all regions.

The Banking operating segment also includes activities surrounding PCI loans and other assets acquired under FDIC loss share agreements. 

The Wealth Management operating segment includes the Trust division of the Bank and the state tax credit brokerage activities. The Trust division provides estate planning, investment management, and retirement planning as well as strategic planning and management succession issues. State tax credits are part of a fee initiative designed to augment the Company’s Wealth Management segment and Banking lines of business.

The Company's Corporate and Intercompany activities represent the elimination of items between segments as well as Corporate related items that management feels are not allocable to either of the two respective segments.

The financial information for each business segment reflects that information which is specifically identifiable or which is allocated based on an internal allocation method. There were no material intersegment revenues among the two segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. When appropriate, these changes are reflected in prior year information presented below.

Following are the financial results for the Company’s operating segments.

At June 30, 2014, and December 31, 2013, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than the U.S. government agencies and sponsored enterprises. The residential mortgage-backed securities are all issued by U.S. government sponsored enterprises. Available for sale securities having a fair value of $244.6 million and $270.1 million at June 30, 2014, and December 31, 2013, respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions.

The amortized cost and estimated fair value of debt securities classified as available for sale at June 30, 2014, 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 5 years.

The unrealized losses at both June 30, 2014, and December 31, 2013, were primarily attributable to changes in market interest rates since the securities were purchased. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. At June 30, 2014, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

The gross gains and gross losses realized from sales of available-for-sale investment securities were as follows:

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. Common shares outstanding include common stock and restricted stock awards where recipients have satisfied the vesting terms. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method for convertible trust preferred securities.

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

	Three months ended June 30,				Six months ended June 30,
(in thousands, except per share data)	2014		2013		2014		2013
Net income as reported	$	7,160	$	11,033	$	13,008	$	21,073

Interest on 9% convertible trust preferred securities, net of income tax	—		354		66		709
Net income available to common shareholders and assumed conversions	$	7,160	$	11,387	$	13,074	$	21,782
Weighted average common shares outstanding	19,824		18,119		19,673		18,052
Incremental shares from assumed conversions of convertible trust preferred securities	—		1,439		115		1,439
Additional dilutive common stock equivalents	139		153		168		115
Weighted average diluted common shares outstanding	19,963		19,711		19,956		19,606
Basic earnings per common share:	$	0.36	$	0.61	$	0.66	$	1.17
Diluted earnings per common share:	$	0.36	$	0.58	$	0.66	$	1.11

For the three months ended June 30, 2014 and 2013, the amount of common stock equivalents that were excluded from the earnings per share calculations because their effect was anti-dilutive was 289,469, and 551,667 common stock equivalents, respectively. For the six months ended June 30, 2014 and 2013, the amount of common stock equivalents that were excluded from the earnings per share calculations because their effect was anti-dilutive was 286,469, and 547,356 common stock equivalents (including 14,324 common stock warrants), respectively.

New Authoritative Accounting Guidance (Notes)

6 Months Ended

Jun. 30, 2014

Prospective Adoption of New Accounting Pronouncements [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

NEW AUTHORITATIVE ACCOUNTING GUIDANCE

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, (“ASU 2014-09”), “Revenue from Contracts with Customers”. The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle of ASU 2014-09 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the new guidance, an entity will (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the contract’s performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification. The new guidance is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 for public companies. Early adoption is not permitted. Entities have the option of using either a full retrospective or modified approach to adopt ASU 2014-09. The Company is currently evaluating the new guidance and has not determined the impact this standard may have on its financial statements nor decided upon the method of adoption.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

The Company issues financial instruments with off balance sheet risk in the normal course of the 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 under commitments to extend credit and standby letters of credit in the event of nonperformance by the other party to the financial instrument 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. At June 30, 2014, there were no unadvanced commitments on impaired loans compared to $0.1 million at December 31, 2013. Other liabilities include approximately $0.2 million at both June 30, 2014 and December 31, 2013 for estimated losses attributable to the unadvanced commitments.

The contractual amounts of off-balance-sheet financial instruments as of June 30, 2014, and December 31, 2013, are as follows:

(in thousands)	June 30, 2014		December 31, 2013
Commitments to extend credit	$	836,110	$	804,420
Standby letters of credit	47,304		44,376

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, 2014, and December 31, 2013, approximately $69.3 million and $50.3 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. The type of collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance 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 standby letters of credit is essentially the same as the risk involved in extending loans to customers. The remaining terms of standby letters of credit range from 1 month to 4 years at June 30, 2014.

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.

The Company grants commercial, real estate, and consumer loans primarily in the St. Louis, Kansas City and Phoenix metropolitan areas. 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 is concentrated in and 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 Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, and current economic factors, among other factors. The Company uses the following definitions for risk ratings:

• Grades 1, 2, and 3- These grades include 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- This grade includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow.

• Grade 5- This grade includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow.

• Grade 6- This grade 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 circumstanceswhere 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 - Watch 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 will include those borrowers that are 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.

Accounting Policies [Abstract]

Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]

Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value.

Basis of Accounitng and Consolidation, Policy

Basis of Financial Statement Presentation

The condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and footnotes required by U.S. GAAP for annual financial statements. 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, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.
