EXPLANATORY NOTE

In January 2012, while converting to a new system designed to address the complex accounting requirements of acquired loans under Accounting Standards Codification ("ASC") Topic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality”, the Company discovered an error in its process used to record income on these loans. ASC 310-30 is utilized to account for the loans acquired by the Company under loss sharing agreements with the Federal Deposit Insurance Corporation (the “FDIC”). Under ASC 310-30, these acquired loans are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the "accretable yield", is recognized as interest income on a level-yield method over the life of the loans. In accounting for income from the acquired loans, the Company recorded both the accretable yield and contractually required interest payments. The Company should not have recognized the contractually required interest payments. As a result, both interest income and the carrying value of the acquired loans were overstated. This affected income reported on the loans acquired in FDIC assisted transactions since December 2009.

The Company is filing this Amendment to our Quarterly Report on Form 10-Q/A (the “Amended Filing” or “Form 10-Q/A”) to restate our unaudited consolidated financial statements and related disclosures for the quarter and year-to-date period ended June 30, 2011 (the "Restatement".) The Quarterly Report on Form 10-Q for the quarter ended June 30, 2011 (the "Original Filing") was filed with the Securities and Exchange Commission (“SEC”) on August 3, 2011.

The previously issued unaudited condensed financial statements for the quarter ended June 30, 2011 in the Original Filing should no longer be relied upon.

Internal Control Considerations

In conjunction with this finding, management identified control deficiencies in its internal controls over financial reporting associated with the reversal of contractual interest on acquired loans that constitute a material weakness, as discussed in Part I, Item 4 of this Form 10-Q/A. A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim consolidated financial statements will not be prevented or detected. For a discussion of management’s consideration of our disclosure controls and procedures and material weaknesses identified, see Part I, Item 4 included in this Amended Filing.

Adjustments

In addition to the adjustments relating to the acquired loan contractual interest described above, the Company has corrected other errors that had been previously identified but not corrected because they were not material, individually or in the aggregate, to the consolidated financial results. These items included changes in accrual estimates and financial statement reclassifications. Adjustments, identified subsequent to the date of the Original Filing date, have also been made to the preliminary fair values of assets acquired and liabilities assumed for the Company's FDIC-assisted transactions.

Additional information on the effect of the adjustments in our financial statements are contained in Item 8, Note 12 - Restatement of Consolidated Financial Results.

For convenience of the reader, this Amended Filing sets forth the Original Filing in its entirety. The sections of the Original Filing which were not amended are unchanged and continue in full force and effect as originally filed. This Amended Filing speaks as of the date of the Original Filing on the Form 10-Q, and has not been updated to reflect

events occurring subsequent to the Original Filing date other than those associated with the correction of the error and other adjustments specifically noted. The Items in this Form 10-Q/A which are amended and restated as a result of the foregoing are:

• Part I, Item 1. - Restated Financial Statements;

• Part I, Item 2. - Management’s Discussion and Analysis of Financial Condition and Results of Operations;

• Part I, Item 4. - Controls and Procedures; and

• Part II - Item 6. Exhibits

In accordance with applicable SEC rules, this Amended Filing includes certifications from our Chief Executive Officer and Chief Financial Officer dated as of the date of this Amended Filing.

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”).

On January 7, 2011, the Bank entered into a purchase and assumption agreement with the Federal Deposit Insurance Corporation (“FDIC”) and acquired certain assets and assumed certain liabilities of Legacy Bank, a full service community bank that was headquartered in Scottsdale, Arizona. For more information on this transaction, see Note 3 - Acquisitions in this report.

On June 24, 2011, the Bank entered into a purchase and assumption agreement with BankLiberty of Liberty, Missouri. Pursuant to the agreement, the Bank expects to purchase certain furniture and equipment, leasehold improvements and assume certain deposit liabilities associated with the BankLiberty branch located at 11401 Olive Boulevard, in the St. Louis suburb of Creve Coeur, Missouri. See Note 3 - Acquisitions for more information.

Operating results for the six months ended June 30, 2011 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2011. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2010.

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.

Approximately $4.8 million in changes to Other Assets in the Consolidated Statement of Cash Flows as of June 30, 2010 have been reclassified from Operating Activities to Investing Activities to conform with the 2011presentation. This reclassification did not result in any changes to previously reported net income or stockholders' equity.

NOTE 2 - EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per common share data is calculated by dividing net income (loss) available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) 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 securities related to the issuance of trust preferred securities.

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

For the three months ended June 30, 2011 and 2010, there were 0.5 million and 2.2 million of weighted average common stock equivalents excluded from the per share calculations because their effect was anti-dilutive. For the six months ended June 30, 2011 and 2010, there were 0.6 million and 2.3 million of weighted average common stock equivalents excluded from the per share calculations because their effect was anti-dilutive. In addition, at June 30, 2011 and 2010, the Company had outstanding warrants issued to the United States Treasury under the U.S. Treasury Capital Purchase Program to purchase 0.3 million shares of common stock which were excluded from the per common share calculation because their effect was also anti-dilutive.

NOTE 3 - ACQUISITIONS

Acquisition of Legacy Bank

On January 7, 2011, the Bank entered into a purchase and assumption agreement with the FDIC and acquired certain assets and assumed certain liabilities of Legacy Bank (“Legacy”), a full service community bank that was headquartered in Scottsdale, Arizona. The acquisition consisted of tangible assets with estimated fair values of approximately $128.0 million and tangible liabilities with estimated fair values of approximately $130.4 million. The Bank acquired the assets at a discount of 7.6% and approximately $43.5 million of the deposits were assumed at a premium of 1%. The Bank also acquired approximately $55.6 million of discretionary and $13.6 million of non-discretionary trust assets.

As part of the acquisition, the Company provided the FDIC with a Value Appreciation Instrument (“VAI”) whereby 372,500 units were awarded to the FDIC at an exercise price of $10.63 per unit. The units were exercisable at any time from January 14, 2011 until January 6, 2012. The FDIC exercised the units on January 20, 2011 at a settlement price of $11.8444 per unit. A cash payment of $452,364 was made to the FDIC on January 21, 2011.

In connection with the acquisition, the Bank also entered into a loss share agreement whereby the FDIC will reimburse the Bank for 80% of all losses incurred on certain loans and other real estate covered under the agreement (“Covered Assets”). The loss share agreement is subject to the servicing procedures as specified in the agreement with the FDIC.

6

The reimbursable losses from the FDIC are based on the book value of the Covered Assets as determined by the FDIC as of the date of the acquisition. A majority of these loans were valued based on the liquidation value of the underlying collateral because the future cash flows are primarily based on the liquidation of underlying collateral. The expected reimbursements under the loss share agreement were recorded as a FDIC loss share receivable at their estimated fair value.

The loans and other real estate acquired are recorded at estimated fair value. As such, there was no allowance for credit losses established related to the acquired loans at January 7, 2011 and no carryover of the related allowance from Legacy. The loans are accounted for in accordance with guidance for certain loans acquired in a transfer, when the loans have evidence of credit deterioration and it is probable at the date of acquisition that the acquirer will not collect all contractually required principal and interest payments. The difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges and an adjustment in accretable yield, which will have a positive impact on interest income.

The table below summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition. The table includes adjustments subsequent to the date of the Original Filing on Form 10-Q. These fair value estimates are considered preliminary, and are subject to change for up to one year after the closing date of the acquisition as additional information relative to closing date fair values becomes available.

Management concluded that it is impracticable to present pro forma financial results due to the lack of documentation and objective information about significant estimates and management’s intent in prior periods.

Acquisition of BankLiberty branch

On June 24, 2011, the Bank entered into a purchase and assumption agreement with BankLiberty in Liberty, Missouri. Pursuant to the agreement, the Bank expects to purchase certain furniture and equipment, leasehold improvements and assume certain deposit liabilities associated with the BankLiberty branch located at 11401 Olive Boulevard, in the St. Louis suburb of Creve Coeur, Missouri. Enterprise expects to pay $150,000 for the personal property in the branch and a deposit premium of 0.75% of certain deposit liabilities at closing. In conjunction with the purchase and assumption agreement, the Bank also will execute a full-service sublease on approximately 6,556 square feet at the above address. Enterprise expects to operate the location as a full-service branch of the Bank, subject to regulatory approval, beginning in the fourth quarter of 2011.

At June 30, 2011 and December 31, 2010, 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 carrying value of $216.9 million and $249.6 million at June 30, 2011 and December 31, 2010, 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, 2011, 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 4 years.

The unrealized losses at both June 30, 2011 and December 31, 2010, were 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, 2011, 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:

	Three months ended June 30,				Six months ended June 30,

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.

There was one loan over 90 days past due and still accruing interest at June 30, 2011. If interest on impaired loans would have been accrued based upon the original contractual terms, such income would have been $891,000 and $1.5 million, for the three and six months ended June 30, 2011, respectively. The cash amount collected and recognized as interest income on impaired loans was $74,000 and $203,000 for the three and six months ended June 30, 2011, respectively. The amount recognized as interest income on impaired loans continuing to accrue interest was $62,000 and $213,000 for the three and six months ended June 30, 2011, respectively. At June 30, 2011, there were $1.6 million of unadvanced commitments on impaired loans. Other Liabilities include approximately $321,000 for estimated losses attributable to the unadvanced commitments on impaired loans.

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. This analysis is performed on a quarterly basis. 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.

17

• 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 circumstances where the company is starting to reverse a negative trend or condition, or have recently been upgraded from a 7, 8, or 9 rating.

• Grade 7 – Watch credits are companies that have experienced financial setback of a nature that are not determined to be severe or influence ‘ongoing concern’ expectations. Borrowers within this category are expected to turnaround within a 12-month period of time. Although possible, no loss is anticipated, due to strong collateral and/or guarantor support.

• Grade 8 – Substandard credits will include those companies 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. Borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on non-accrual.

Acquired loans are also subject to the Company’s internal and external credit review and are risk rated using the same criteria as loans originated by the Company. However, risk ratings are not always a clear indicator of the Company's losses on acquired loans as a majority of the losses are recoverable from the FDIC under the loss-sharing agreements.

Portfolio loans covered under FDIC loss share

Purchased loans acquired in a business combination, including loans purchased in our FDIC-assisted transactions, are recorded at estimated fair value on their purchase date without a carryover of the related allowance for loan losses. Purchased credit-impaired loans are loans that have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the purchase date may include factors such as past due and non-accrual status. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable yield. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges or a reclassification of the difference from non-accretable to accretable with a positive impact on interest income. Further, any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows.

20

Changes in the accretable yield for purchased loans were as follows for the six months ended June 30, 2011 and 2010:

(in thousands)	June 30, 2011			June 30, 2010
Balance at beginning of period	$	46,460		$	3,708
Additions	10,875			—
Accretion	(11,433		)	(494		)
Balance at end of period	$	45,902		$	3,214

Outstanding balances on purchased loans from the FDIC were $260.8 million as of June 30, 2011 and $219.5 million at December 31, 2010, respectively. In the second quarter of 2011, the Bank received payments of $10.9 million for loss share claims under the terms of the FDIC loss share agreements.

Legacy acquisition

The following table presents information regarding the contractually required payments receivable, the cash flows expected to be collected, and the estimated fair value of the loans acquired in the Legacy acquisition, at the closing date of the transaction:

(In thousands)	January 7, 2011 Purchased  Credit-Impaired Loans
Contractually required payments (principal and interest):	$	106,286
Cash flows expected to be collected (principal and interest):	84,089
Fair value of loans acquired:	73,214

These amounts were determined based upon the estimated remaining life of the underlying loans, which includes the effects of estimated prepayments. The majority of the purchased credit-impaired loans were valued based on the liquidation value of the underlying collateral. There was no allowance for credit losses on purchased loans related to FDIC-assisted transactions at June 30, 2011.

The determination of the initial fair value of loans and other real estate acquired in the transaction and the initial fair value of the related FDIC loss share receivable involve a high degree of judgment and complexity. The carrying value of the acquired loans and other real estate and the FDIC indemnification asset reflect management’s best estimate of the fair value of each of these assets as of the date of acquisition. However, the amount that the Bank realizes on these assets could differ materially from the carrying value reflected in these financial statements, based upon the timing and amount of collections on the acquired loans in future periods. To the extent the actual values realized for the acquired loans are different from the estimate, the FDIC loss share receivable will generally be affected in an offsetting manner due to the indemnification obligations of the FDIC, thus limiting the Bank’s loss exposure.

NOTE 7 - 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 in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments.

21

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, 2011 there were $1.6 million of unadvanced commitments on impaired loans. Other liabilities include approximately $321,000 for estimated losses attributable to the unadvanced commitments on impaired loans.

The contractual amounts of off-balance-sheet financial instruments as of June 30, 2011 and December 31, 2010 are as follows:

(in thousands)	June 30, 2011		December 31, 2010
Commitments to extend credit	$	445,307	$	429,411
Standby letters of credit	44,598		42,113

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 and may require payment of a fee. Of the total commitments to extend credit at June 30, 2011 and December 31, 2010, approximately $72.1 million and $67.0 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon, 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. 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 letters of credit is essentially the same as the risk involved in extending loans to customers. The approximate remaining term of standby letters of credit range from 6 months to 5 years at June 30, 2011.

Contingencies

The Bank, along with other co-defendants has been named as a defendant in two lawsuits filed by persons alleging to be clients of the Bank’s Trust division who invested in promissory notes issued by Distinctive Properties (UK) Limited (“Distinctive Properties”), a company involved in the purchase and development of real estate in the United Kingdom. Plaintiffs allege that the promissory notes were part of a multi-million dollar Ponzi scheme. Plaintiffs allege to hold such promissory notes in accounts with the Trust division and that, among other things, the Bank was negligent, breached its fiduciary duties and breached its contracts. Plaintiffs also allege that the Bank violated the Racketeer Influenced and Corrupt Organizations Act (“RICO”). Plaintiffs, in the aggregate, are seeking damages from defendants, including the Bank, of approximately $27.0 million as well as their costs and attorneys’ fees and trebled damages under RICO. The Company is unable to estimate a reasonably possible loss for the cases described above because the proceedings are in early stages and there are significant factual issues to be determined and resolved. The Company denies Plaintiffs’ allegations and intends to vigorously defend the lawsuits.

The following litigation was filed subsequent to the Quarterly Report on Form 10-Q for the quarter ended June 30, 2011, which was filed with the Securities and Exchange Commission (“SEC”) on August 3, 2011. On April 10, 2012, a putative class action was filed in the United States District Court for the Eastern District of Missouri captioned William Mark Scott v. Enterprise Financial Services Corp, Peter F. Benoist, and Frank H. Sanfilippo. The complaint asserts claims for violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of a putative class of purchasers of the Company's stock between April 20, 2010 and January 25, 2012, inclusive. The complaint alleges, among other things, that defendants allegedly made false and misleading statements and allegedly "failed to disclose that the Company was improperly recording income on loans covered under loss share agreements with the FDIC" and that, as a result, "the Company's financial statements were materially false and misleading at all relevant times." The action seeks unspecified damages and costs and expenses. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuit.

NOTE 8 - DERIVATIVE FINANCIAL INSTRUMENTS

The Company is a party to various derivative financial instruments that are used in the normal course of business to meet the needs of its clients and as part of its risk management activities. These instruments include interest rate swaps and option contracts. The Company does not enter into derivative financial instruments for trading or speculative purposes.

23

Interest rate swap contracts involve the exchange of fixed and floating rate interest payment obligations without the exchange of the underlying principal amounts. The Company enters into interest rate swap contracts on behalf of its clients and also utilizes such contracts to reduce or eliminate the exposure to changes in the cash flows or fair value of hedged assets or liabilities due to changes in interest rates. Interest rate option contracts consist of caps and provide for the transfer or reduction of interest rate risk in exchange for a fee.

All derivative financial instruments, whether designated as hedges or not, are recorded on the consolidated balance sheet at fair value within Other assets or Other liabilities. The accounting for changes in the fair value of a derivative in the consolidated statement of operations depends on whether the contract has been designated as a hedge and qualifies for hedge accounting. At June 30, 2011 and December 31, 2010, the Company did not have any derivatives designated as cash flow or fair value hedges.

Using derivative instruments means assuming counterparty credit risk. Counterparty credit risk relates to the loss the Company could incur if a counterparty were to default on a derivative contract. Notional amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance sheet. They are used merely to express the volume of this activity. The overall credit risk and exposure to individual counterparties is monitored. The Company does not anticipate nonperformance by any counterparties. The amount of counterparty credit exposure is the unrealized gains, if any, on such derivative contracts. At June 30, 2011, the Company had pledged cash of $1.5 million and accepted pledged securities of $2.8 million as collateral in connection with our interest rate swap agreements. At December 31, 2010, the Company had accepted cash of $530,000, pledged cash of $1.5 million, and accepted pledged securities of $2.2 million as collateral in connection with our interest rate swap agreements.

Risk Management Instruments. The Company enters into certain derivative contracts to economically hedge state tax credits and certain loans.

• Economic hedge of state tax credits. In November 2008, the Company paid $2.1 million to enter into a series of interest rate caps in order to economically hedge changes in fair value of the State tax credits held for sale. In February 2010, the Company paid $751,000 for an additional series of interest rate caps. See Note 10—Fair Value Measurements for further discussion of the fair value of the state tax credits.

• Economic hedge of prime based loans. Previously, the Company had two outstanding interest rate swap agreements whereby the Company paid a variable rate of interest equivalent to the prime rate and received a fixed rate of interest. The swaps were designed to hedge the cash flows associated with a portion of prime based loans and had been designated as cash flow hedges. However, in December 2008, due to a variable rate differential, the Company concluded the cash flow hedges would not be prospectively effective and the hedges were dedesignated. The swaps were terminated in February 2009. The unrealized gain prior to dedesignation was included in Accumulated other comprehensive income and is being amortized over the expected life of the related loans. At June 30, 2011, the amount remaining in Accumulated other comprehensive income is $47,000. For the three months ended June 30, 2011 and 2010, $44,000 and $62,000 was reclassified into Miscellaneous income, respectively. For the six months ended June 30, 2011 and 2010, $88,000 and $124,000 was reclassified into Miscellaneous income, respectively. The Company expects to reclassify $74,000 of remaining derivative gains from Accumulated other comprehensive income and deferred taxes to earnings over the next five months.

• 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. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions. Through June 30, 2011, Level 3 securities available for sale include three Auction Rate Securities and a municipal bond issued by a school district.

• 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, 2011, of the $57.1 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $29.2 million were carried at fair value. The remaining $27.9 million of state tax credits were accounted for at cost.

The fair value of the state tax credits carried at fair value increased $198,000 for the quarter ended June 30, 2011 compared to a $1.1 million increase for the same period in 2010. These fair value changes are included in Gain on State tax credits, net in the condensed consolidated statements of operations.

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 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. Assuming that the

28

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 fair value 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 defined as 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. 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.

29

Level 3 financial instruments

The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis as of June 30, 2011.

• Purchases, sales, issuances and settlements, net. There were no purchases of Level 3 financial instruments during the quarter ended June 30, 2011. Sales of Level 3 instruments are shown in the table below.

• Transfers in and/or out of Level 3. The transfer out of Level 3 is related to two newly issued mortgage-backed securities purchased in the fourth quarter of 2010 which were originally priced using Level 3 assumptions. In the first quarter of 2011, a third party pricing service became available.

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, 2011.

	(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) gains for the six months ended June 30, 2011

(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. Fair values for impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Other real estate owned is adjusted to fair value upon foreclosure of the underlying loan. 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. Certain state tax credits are reported at cost.

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, 2011 and December 31, 2010.

NOTE 11 - 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 Wealth Management 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 consulting on management compensation, 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 Corporate segment’s principal activities include the direct ownership of the Company’s banking subsidiary and the issuance of debt and equity. Its principal source of liquidity is dividends from its subsidiaries and stock option exercises.

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 three 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.

NOTE 12 - RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS

Background of the Restatement

In January 2012, while converting to a new system designed to address the complex accounting requirements of acquired loans under Accounting Standards Codification ("ASC") Topic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality”, the Company discovered an error in its process used to record income on these loans. ASC 310-30 is utilized to account for the loans acquired by the Company under loss sharing agreements with the Federal Deposit Insurance Corporation (the “FDIC”). Under ASC 310-30, these acquired loans are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the "accretable yield", is recognized as interest income on a level-yield method over the life of the loans. In accounting for income from the acquired loans, the Company recorded both the accretable yield and contractually required interest payments. The Company should not have recognized the contractually required interest payments. As a result, both interest income and the carrying value of the acquired loans were overstated. This affected income reported on the loans acquired in FDIC assisted transactions since December 2009.

Other Adjustments

In addition to the adjustments relating to the acquired loan contractual interest described above, the Company has corrected other errors that had been previously identified but not corrected because they were not material, individually or in the aggregate, to the consolidated financial results. These items included changes in accrual estimates and financial statement reclassifications.

ITEM 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

38

As discussed in the Explanatory Note and Note 12 - Restatement of Consolidated Financial Statements of this Amended Filing, the Company has restated its previously issued unaudited condensed consolidated financial statements for the three and six months ended June 30, 2011 and 2010. Management's Discussion and Analysis of Financial Condition and Results of Operations have been revised for the effects of the restatement.

Some of the information in this report contains “forward-looking statements” within the meaning of and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements typically are identified with use of terms such as “may,” “might,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “could,” “continue” and the negative of these terms and similar words, although some forward-looking statements are expressed differently. Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. You should be aware that our actual results could differ materially from those contained in the forward-looking statements due to a number of factors, including, but not limited to: credit risk; changes in the appraised valuation of real estate securing impaired loans; outcomes of litigation and other contingencies; exposure to general and local economic conditions; risks associated with rapid increases or decreases in prevailing interest rates; consolidation within the banking industry; competition from banks and other financial institutions; our ability to attract and retain relationship officers and other key personnel; burdens imposed by federal and state regulation; changes in accounting regulation or standards applicable to banks; and other risks discussed under the caption “Risk Factors” of our most recently filed Form 10-K and in Part II, 1A of this Form 10-Q, all of which could cause the Company’s actual results to differ from those set forth in the forward-looking statements.

Readers are cautioned not to place undue reliance on our forward-looking statements, which reflect management’s analysis and expectations only as of the date of such statements. Forward-looking statements speak only as of the date they are made, and the Company does not intend, and undertakes no obligation, to publicly revise or update forward-looking statements after the date of this report, whether as a result of new information, future events or otherwise, except as required by federal securities law. You should understand that it is not possible to predict or identify all risk factors. Readers should carefully review all disclosures we file from time to time with the Securities and Exchange Commission which are available on our website at www.enterprisebank.com.

Introduction

The following discussion describes the significant changes to the financial condition of the Company that have occurred during the first six months of 2011 compared to the financial condition as of December 31, 2010. In addition, this discussion summarizes the significant factors affecting the results of operations, liquidity and cash flows of the Company for the three and six months ended June 30, 2011, compared to the same periods in 2010. This discussion should be read in conjunction with the accompanying consolidated financial statements included in this report and our Annual Report on Form 10-K/A for the year ended December 31, 2010.

Executive Summary

The Company reported net income of $8.3 million million for the three months ended June 30, 2011, compared to net income of $577,000 for the same period in 2010. After deducting dividends on preferred stock, the Company reported net income per fully diluted share of $0.43, compared to net income of $0.00 per fully diluted share for the prior year period. During the second quarter of 2011, higher than expected yields on covered loans and a related reduction of fee income for the indemnification asset contributed to the earnings per share. See Net Interest Income and Non Interest Income in this section for more information.

Net income for the six months ended June 30, 2011 was $12.4 million compared to a net loss of $2.6 million for the same period in 2010. After deducting dividends on preferred stock, the Company reported net income per fully diluted share of $0.70, compared to a net loss of $0.26 per fully diluted share for the prior year period.

On January 7, 2011, the Bank entered into a purchase and assumption agreement with the FDIC and acquired certain assets and assumed certain liabilities of Legacy Bank, a full service community bank that was headquartered in Scottsdale, Arizona. The acquisition consisted of assets with an estimated fair value of approximately $128.6 million and liabilities with an estimated fair value of approximately $130.4 million.

In connection with the acquisition, the Bank also entered into a loss share agreement whereby the FDIC will reimburse the Bank for 80% of all losses incurred on certain loans and other real estate covered under the agreement. The Bank acquired the assets at a discount of 7.6% and approximately $43.5 million of the deposits were assumed at a premium of 1%. The two branches of Legacy opened as branches of the Bank. The Bank also acquired approximately $55.6 million of discretionary and $13.6 million of non-discretionary trust assets. See Note 3 – Acquisitions and Note 6 – Portfolio Loans for more information.

On May 24, 2011, the Company issued $35.0 million in common stock through a public offering. The shares in the offering were issued pursuant to a prospectus supplement filed with the Securities and Exchange Commission as part of the Company's effective registration statement. See Capital Resources for more information.

The Company's pre-tax, pre-provision income for the second quarter of 2011 was $18.8 million, an increase of $9.3 million, or 98%, compared to the second quarter of 2010. The increase in pre-tax, pre-provision income was a result of a combination of strong returns on our Arizona covered loan portfolio and substantial organic growth in commercial and industrial loans. Improving asset quality and moderating provision expense are also contributing to increased earnings. In addition, the Company has been systematically reducing funding costs by lowering deposit rates and increasing noninterest-bearing demand deposits. The strong growth in commercial loan fundings and commercial demand deposits result from our continued focus on privately held businesses and success in recruiting accomplished commercial bankers to the Enterprise platform in all three of our markets.

40

Pre-tax, pre-provision income, which is a non-GAAP (accounting principles generally accepted in the United States of America) financial measure, is presented because the Company believes adjusting its results to exclude loan loss provision expense, sales and fair value writedowns of other real estate, and sales of securities provides shareholders with a more comparable basis for evaluating period-to-period operating results. A schedule reconciling GAAP pre-tax income (loss) to pre-tax, pre-provision income is provided in the table below.

Below are highlights of our Banking and Wealth Management segments. For more information on our segments, see Note 11 –Segment Reporting.

Banking Segment

• Loans - Portfolio loans totaled $2.0 billion at June 30, 2011, including $169.1 million of loans covered under FDIC loss share agreements. Portfolio loans covered under FDIC loss share agreements decreased $13.2 million, or 7%, in the second quarter of 2011, primarily as a result of loan payoffs and transfers to Other Real Estate. Excluding the loans covered under loss share, total portfolio loans increased $65.2 million, or 4%, in the second quarter of 2011. Commercial & Industrial loans increased $75.4 million, or 12%, during the quarter and represent one-third of the Company's loan portfolio at June 30, 2011. This growth represents the fourth consecutive quarter of increases in Commercial and Industrial loans as the Company continues to experience strong new business activity in this sector. Construction and Residential Real Estate decreased $15.7 million as the Company continued to reduce its exposure to these sectors. Portfolio loans increased by $107.4 million, or 6%, from December 31, 2010 and $223.5 million, or 13%, from June 30, 2010.

We continue to expect low to mid single digit loan growth for 2011. See Note 6 – Portfolio Loans for more information.

• Deposits – Total deposits at June 30, 2011 were $2.4 billion, and $113.6 million, or 5%, higher than December 31, 2010 and $589.5 million, or 32%, higher than June 30, 2010. Core deposits, which exclude brokered certificates of deposit and include reciprocal CDARS deposits, decreased $9.1 million, or 0.40%, in the second quarter of 2011 compared to the first quarter of 2011. Core deposits increased $123.6 million, or 6% from December 31, 2010 and $544.2 million, or 32%, from June 30, 2010. Core deposits represented 94% of total deposits at June 30, 2011, March 31, 2011 and June 30, 2010. The Company continued to improve its core deposit mix with a $25.7 million increase in demand deposits, and a $21.6 million increase in money market accounts and other interest-bearing transaction accounts. The Company lowered its reliance on certificates of deposit by reducing non-CDARS certificates by $16.9 million and reciprocal CDARS certificates by $39.5 million in the second quarter of 2011. Reciprocal CDARS certificates were $35.3 million at June 30, 2011 compared to $160.5 million at December 31, 2010 and $157.5 million at June 30, 2010.

Noninterest-bearing demand deposits were $473.7 million at June 30, 2011, an increase of 29% from December 31, 2010 and a 61% increase from June 30, 2010. Noninterest-bearing demand deposits represented 20% of total deposits at June 30, 2011 compared to 16% at December 31, 2010 and 16% at June 30, 2010. Demand deposit growth is attributable to intensified sales efforts and continuing emphasis on liquidity and safety among commercial

41

clients. Year-over-year growth in noninterest-bearing demand deposits was bolstered by three client relationships totaling $72.6 million. Absent those relationships, demand deposits increased 37% from June 30, 2010 to June 30, 2011.

• Asset quality – Nonperforming loans, including troubled debt restructurings of $11.4 million, were $43.1 million at June 30, 2011, compared to $46.4 million at December 31, 2010 and $46.6 million at June 30, 2010. Nonperforming loans represented 2.16% of total loans at June 30, 2011 versus 2.46% of total loans at December 31, 2010 and 2.63% at June 30, 2010. New nonperforming inflows in the second quarter of $9.5 million represent the lowest level of new nonperforming loan inflows in over two years. Excluding non-accrual loans and portfolio loans covered under FDIC loss share agreements, portfolio loans that were 30-89 days delinquent at June 30, 2011 remained at very low levels, representing 0.21% of the portfolio compared to 0.13% at December 31, 2010 and 0.86% of June 30, 2010.

Provision for loan losses was $4.6 million in the second quarter of 2011, compared to $3.6 million in the first quarter of 2011 and significantly less than the $9.0 million recorded in the second quarter of 2010. The increase in the provision for loan losses in the second quarter of 2011 was due to slightly higher levels of loan risk rating downgrades and loan growth in the quarter. See Note 6 – Portfolio Loans above and Provision and Allowance for Loan Losses and Nonperforming Assets in this section for more information.

• Interest rate margin – The net interest rate margin was 4.75% for the second quarter of 2011, compared to 3.58% for the first quarter of 2011 and 3.43% in the second quarter of 2010. For the six month period ended June 30, 2011, the net interest rate margin was 4.17% compared to 3.42% for the same period in 2010. See Net Interest Income in this section for more information.

Wealth Management Segment

Fee income from the Wealth Management segment includes Wealth Management revenue and income from state tax credit brokerage activities. Wealth Management revenue was $1.7 million in the second quarter of 2011, flat with the linked first quarter and an increase of $110,000, or 7%, compared to June 30, 2010. See Noninterest Income in this section for more information. 

Net Interest Income

Three months ended June 30, 2011 and 2010

Net interest income (on a tax-equivalent basis) was $31.3 million for the three months ended June 30, 2011 compared to $18.7 million for the same period of 2010, an increase of $12.6 million, or 67%. Total interest income increased $12.1 million and total interest expense decreased $553,000.

Average interest-earning assets increased $458.4 million, or 21%, to $2.6 billion for the quarter ended June 30, 2011 from $2.2 billion for the quarter ended June 30, 2010. Average loans increased $185.2 million, or 10%, to $2.0 billion for the quarter ended June 30, 2011 from $1.8 billion for the quarter ended June 30, 2010. Approximately $160.4 million of the increase is related to the Home National Bank and Legacy acquisitions. Average securities and short-term investments increased $273.2 million, or 67%, to $682.7 million from the second quarter of 2010 as increased core deposits were deployed to offset weak loan demand. Interest income on earning assets increased $11.5 million due to higher volume and $604,000 due to higher rates, for an increase of $12.1 million versus the second quarter of 2010.

For the quarter ended June 30, 2011, average interest-bearing liabilities increased $378.4 million, or 20%, to $2.2 billion compared to $1.9 billion for the quarter ended June 30, 2010. The increase in average interest-bearing liabilities resulted from a $362.4 million increase in average interest-bearing deposits, primarily consisting of $293.7 million increase in average money market accounts and a $71.7 million increase in average certificates of deposit. For the second quarter of 2011, interest expense on interest-bearing liabilities decreased $1.7 million due to declining rates partially offset by an increase of $1.1 million due to the impact of higher volumes, for a net decrease of $553,000 versus the second quarter of 2010.

42

The tax-equivalent net interest rate margin was 4.75% for the second quarter of 2011, compared to 3.58% for the first quarter of 2011 and 3.43% in the second quarter of 2010. In the second quarter of 2011, the loans covered under FDIC loss share yielded 25.33% primarily due to cash flows on paid off covered loans that exceeded expectations. Absent the FDIC loss share loans and related funding, the net interest rate margin was 3.45% for the second quarter of 2011 compared to 3.33% for the first quarter of 2011. The increase in the net interest rate margin, excluding the effect of loans covered under FDIC loss share, was primarily due to a more favorable earning asset mix and lower cost of funds.

The Company expects low to mid-single digit growth during 2011 in portfolio loans not covered under FDIC loss share. The growth is expected to be primarily in the Commercial & Industrial loan category. Pipelines for new loan activity have continued to strengthen over the past several months.

Six months ended June 30, 2011 and 2010

Net interest income (on a tax-equivalent basis) was $54.3 million for the six months months ended June 30, 2011 compared to $37.3 million for the same period of 2010, an increase of $17.0 million, or 46%. Total interest income increased $15.7 million and total interest expense decreased $1.4 million.

Average interest-earning assets increased $431.3 million, or 20%, to $2.6 billion for the six months ended June 30, 2011 from $2.2 billion for the six months ended June 30, 2010. Average loans increased $160.0 million, or 9%, to $2.0 billion for the six months ended June 30, 2011 from $1.8 billion for the six months ended June 30, 2010. Average

securities and short-term investments increased $271.4 million, or 68%, to $668.6 million from the same period in 2010. Interest income on earning assets increased $16.0 million due to higher volume and decreased $310,000 due to lower rates, for a net increase of $15.7 million versus the six months ended June 30, 2010.

For the six months ended June 30, 2011, average interest-bearing liabilities increased $391.5 million, or 21%, to $2.3 billion compared to $1.9 billion for the same period in 2010. The increase in average interest-bearing liabilities resulted from a $361.2 million increase in average interest-bearing deposits, primarily consisting of $271.2 million increase in average money market accounts and a $86.3 million increase in average certificates of deposit.

For the six months ended June 30, 2011, interest expense on interest-bearing liabilities decreased $3.9 million due to declining rates partially offset by an increase of $2.5 million due to the impact of higher volumes, for a net decrease of $1.4 million versus the same period in 2010.

The tax-equivalent net interest rate margin was 4.17% for the six months ended June 30, 2011, compared to 3.42% in the same period of 2010. The increase in the margin was primarily due to a higher yield and higher balance on covered loans, lower funding costs and a better funding mix relative to the same period in 2010.

Provision and Allowance for Loan Losses

Provision for loan losses was $4.6 million in the second quarter of 2011 compared to $3.6 million in the first quarter of 2011 and significantly less than the $9.0 million recorded in the second quarter of 2010. The increase in the provision for loan losses in the second quarter of 2011 versus the linked first quarter was due to slightly higher levels of loan risk rating downgrades and net loan growth. The allowance for loan losses was 2.11% of total loans at June 30, 2011, representing 98% of nonperforming loans. The loan loss allowance was 2.20% at March 31, 2011 representing 98% of nonperforming loans and 2.55% at June 30, 2010 representing 97% of nonperforming loans. Management believes

46

that the allowance for loan losses is adequate to absorb inherent losses in the loan portfolio.

Net charge-offs in the second quarter of 2011 were $5.2 million, representing an annual rate of 1.07% of average loans, compared to net charge-offs of $3.5 million, an annualized rate of 0.73%% of average loans, in the linked first quarter and $7.8 million, an annualized rate of 1.76% of average loans, in the second quarter of 2010. Approximately 77% of the net charge-offs in the second quarter of 2011 were related to Construction Land Acquisition and Development loans, 12% were related to Residential Real Estate loans, 9% were related to Commercial & Industrial loans and the remaining 2%were related to Commercial Real Estate loans.

For the six months ended June 30, 2011, net charge-offs were $8.8 million, compared to net charge-offs of $20.5 million for the same period in 2010. Approximately 75% of the charge-offs for the six months ended June 30, 2011 were related to Construction, Land Acquisition and Development loans, 10% were related to Commercial Real Estate loans, 9% were related to Commercial & Industrial loans, and the remaining 6% were related to Residential Real Estate loans.

Nonperforming loans

Nonperforming loans exclude credit-impaired loans that were acquired in the December 2009, July 2010, and January 2011 FDIC-assisted transactions. These purchased credit-impaired loans are accounted for on a pool basis, and the pools are considered to be performing. See Note 6 – Portfolio Loans for more information on these loans.

Nonperforming loans, including troubled debt restructurings of $11.4 million were $43.1 million at June 30, 2011, flat with $43.5 million at March 31, 2011 and down from $46.6 million at June 30, 2010. During the quarter ended June 30, 2011, there were $9.5 million of additions to nonperforming loans, $5.7 million of chargeoffs, $4.0 million of other principal reductions, and $159,000 of assets transferred to other real estate. The $9.5 million represents the lowest level of new nonperforming loan inflows in over two years. Six construction real estate loans representing three relationships comprised over $5.1 million, or 54% of the total new nonperforming loans, while three commercial real estate loans representing two relationships comprised $1.6 million, or 17%.

48

Nonperforming loans represented 2.16% of total loans at June 30, 2011 versus 2.24% of total loans at March 31, 2011 and 2.63% at June 30, 2010.

The nonperforming loans are comprised of approximately 41 relationships with the largest being a $5.4 million loan secured by commercial land in Kansas City. Eight relationships comprise 65% of the nonperforming loans. Approximately 55% of the nonperforming loans were located in the Kansas City market and 45% were located in the St. Louis market. At June 30, 2011, there were no performing restructured loans that have been excluded from the nonperforming loan amounts.

Other real estate end of period	$	42,790		$	51,305		$	42,790

At June 30, 2011, Other real estate was comprised of 20% residential lots, 22% completed homes, and 58% commercial real estate. Of the total Other real estate, 14%, or 22 properties, are located in the Kansas City region, 35%, or 14 properties, are located in the St. Louis region and 51%, or 47 properties, are located in the Arizona region related to the FDIC acquisitions.

The writedowns in fair value were recorded in Loan legal and other real estate expense based on current market activity shown in the appraisals. In addition, for the six months ended June 30, 2011, the Company realized a net gain of $522,000 on the sale of other real estate and recorded these gains as part of Noninterest income.

Excluding covered assets, the Company expects continued gradual improvement in the ratio of nonperforming assets to total assets.

Noninterest Income

Noninterest income decreased $1.1 million, or 20%, from the second quarter of 2010 compared to the second quarter of 2011. The decrease is primarily due to reductions in the accretion on the indemnification asset on our Covered Assets.

For the six months ended June 30, 2011, Noninterest income decreased $403,000, or 4%, from the same period in 2010. The decrease is primarily due to reductions in the accretion on the indemnification asset on our Covered Assets.

offset by increases in Wealth Management revenue.

• Wealth Management revenue– For the quarter ended June 30, 2011, Wealth Management revenue from the Trust division increased 110,000, or 7%, compared to the same period in 2010. Year-to-date, Trust revenues increased $255,000, or 8%, over the same period in 2010. Assets under administration were $1.6 billion at June 30, 2011, a 28% increase from June 30, 2010 due to market value increases and additional accounts from new and existing clients, including acquired Legacy Trust assets.

• Sale of other real estate – For the quarter ended June 30, 2011, we sold $9.0 million of Other real estate for a gain of $99,000. Year-to-date through June 30, 2011, we sold $13.1 million of Other real estate for a net gain of $522,000. For the year-to-date period in 2010, we sold $14.3 million of Other real estate for a net gain of $290,000.

• State tax credit brokerage activities– For the quarter ended June 30, 2011, the Company recorded a gain of $987,000 compared to a gain of $851,000 in the second quarter of 2010. Gains of $990,000 related to the sale of state tax credits to clients and a positive fair value adjustment of $198,000 and were partially offset by a negative fair value adjustment of $201,000 on the interest rate caps used to economically hedge the tax credits. See Note 8 – Derivatives Instruments and Hedging Activities above for more information on the interest rate caps. For more information on the fair value treatment of the state tax credits, see Note 10 – Fair Value Measurements.

• Sale of investment securities – During the first six months of 2011, the Company purchased approximately $194.3 million in securities primarily in U.S. Government sponsored enterprises and Residential mortgage-backed securities. The Company sold approximately $35.4 million of securities realizing a gain of $680,000 on these sales.

• Miscellaneous income – Accretion of the indemnification asset related to the FDIC acquisitions decreased $1.2 million in the second quarter of 2011 compared to the same quarter in 2010. The decrease included $2.5 million of reduced accretion related to loan pay offs in which was losses were less than expected. Year-to-date through June 30, 2011, Miscellaneous income decreased $332,000, or 39%, compared to the same period in 2010 primarily due to a net decrease of $622,000 of accretion related to the indemnification assets of the Home National Bank and Valley Capital Covered Loan portfolios partially offset by an increase of $169,000 in Bank Owned Life Insurance cash value.

Noninterest Expense

Noninterest expenses were $18.0 million in the second quarter of 2011, an increase of $3.6 million, or 25%, from the same quarter of 2010. The increase over the prior year period was comprised of $1.2 million in salaries and benefits primarily due to variable compensation accruals and staff additions to support the Company's Arizona acquisition activity and $1.6 million in higher loan legal and other real estate expenses. The Company also incurred additional property, equipment and data processing costs due to our Arizona acquisition activity and increases in FDIC insurance premiums due to the higher levels of deposits.

For the six months ended June 30, 2011, noninterest expenses were $36.0 million compared to $28.3 million for the same period in 2010. The increase of $7.7 million over the prior year period was comprised of $3.3 million in salaries and benefits primarily due to variable compensation accruals and staff additions to support the Company's Arizona acquisition activity and $2.8 million in higher loan legal and other real estate expenses.

The Company's efficiency ratio was 51.2% for the quarter ended June 30, 2011 compared to 60.7% for the prior year period. Year-to-date through June 30, 2011 the Company's efficiency ratio was 57.2% compared to 61.0% for the same period in 2010. The dramatic improvement in this ratio during 2011 related primarily to the net results from our FDIC-assisted transactions.

Income Taxes

For the quarter ended June 30, 2011, the Company’s income tax expense, which includes both federal and state taxes, was $4.4 million compared to a $0.2 million benefit for the same period in 2010. The combined federal and state effective income tax rates were 34.5% and 55.1% for the quarter months ended June 30, 2011 and 2010, respectively.

For the six months ended June 30, 2011, the Company’s income tax expense, which includes both federal and state taxes, was $6.3 million compared to a $2.1 million benefit for the same period in 2010. The combined federal and state effective income tax rates were 33.9% and 44.1% for the six months ended June 30, 2011 and 2010, respectively.

 The Company recognizes deferred tax assets only to the extent that they are expected to be used to reduce amounts that have been paid or will be paid to tax authorities. Management believes, based on all positive and negative evidence, that the deferred tax asset of $13.7 million at June 30, 2011 and $17.7 million at December 31, 2010, is more likely-than-not-to be realized, and accordingly, no valuation allowance has been recorded at either date.

Liquidity and Capital Resources

Liquidity management

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

51

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 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.

Our Asset-Liability Management Committee oversees our liquidity position, the parameters of which are approved by the Bank 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). 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 $27.7 million will be sufficient to meet all projected cash needs for at least the next year.

As of June 30, 2011, the Company had $82.6 million of outstanding subordinated debentures as part of nine Trust Preferred Securities Pools. These securities are classified as debt but are included in regulatory capital and the related interest expense is tax-deductible, which makes them a very attractive source of funding.

Bank liquidity

During the second quarter of 2011, we maintained a strong liquidity position by targeting core funding while reducing certain volatile deposit sources. Noninterest-bearing demand deposits grew $25.7 million, and interest-bearing checking and money market accounts increased $21.6 million. This was offset by a decrease of $66.4 million in time deposits, including CDARS and brokered CD balances.

The Bank has a variety of funding sources available to increase financial flexibility. In addition to amounts currently borrowed, at June 30, 2011, the Bank could borrow an additional $114.5 million from the FHLB of Des Moines under blanket loan pledges and has an additional $331.3 million from the Federal Reserve Bank under a pledged loan agreement. The Bank has unsecured federal funds lines with three correspondent banks totaling $35.0 million.

Of the $472.3 million of the securities available for sale at June 30, 2011, $216.9 million was pledged as collateral for deposits of public institutions, treasury, loan notes, and other requirements. The remaining $255.4 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. 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, 2011, the Bank had $56.7 million of reciprocal CDARS money market sweep balances and $35.3 million of reciprocal certificates of deposits outstanding. In addition to the reciprocal deposits available through CDARS, we also have access to the “one-way buy” program, which allows us to bid on the

52

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, 2011, 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. At June 30, 2011, brokered certificate of deposit balances were $146.6 million, and represented 6.1% of total deposits at June 30, 2011.

Over 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 $489.9 million in unused commitments as of June 30, 2011. While this commitment level exceeds the Company's current liquidity resources, the nature of these commitments is such that the likelihood of funding them is low.

Capital Resources

On May 24, 2011, the Company issued $35.0 million in common stock through a public offering. The shares in the offering were issued pursuant to a prospectus supplement filed with the Securities and Exchange Commission as part of the Company's effective registration statement. The net proceeds to the Company, after deducting underwriting discounts and commissions and offering expenses, was approximately $32.6 million. At June 30, 2011, approximately $20.0 million of the offering proceeds were injected into the Bank to support expected growth. The remaining net proceeds from the offering will be used for general corporate purposes, which may include capital to support growth and acquisition opportunities. Absent any significant acquisitions or another economic recession, the Company intends to redeem its $35.0 million of preferred stock held by the U.S. Treasury in 2012 with available cash and bank earnings. The Company has chosen not to participate in the Small Business Lending Fund.

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 banking affiliate’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 total risk-based (10%), Tier 1 risk-based (6%) and Tier 1 leverage ratios (5%). Management believes, as of June 30, 2011 and December 31, 2010, that 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, 2011 and December 31, 2010.

53

The following table summarizes the Company’s risk-based capital and leverage ratios at the dates indicated:

(Dollars in thousands)	June 30, 2011			December 31, 2010

Critical Accounting Policies

The impact and any associated risks related to the Company’s critical accounting policies on business operations are discussed 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 discussion on the application of these and other accounting policies, see the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2010.

New Accounting Standards

FASB ASU 2010-06, “Improving Disclosures about Fair Value Measurements” On January 1, 2011, the Company adopted new authoritative guidance under this ASU, which requires detailed Level 3 roll forward disclosure. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

FASB ASU 2010-20, “Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses” On January 1, 2011, the Company adopted new authoritative guidance under this ASU which requires disclosures about activity that occurs during a reporting period. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

FASB ASU 2010-29, “Business Combinations (Topic 805)—Disclosure of Supplementary Pro Forma Information for Business Combinations” On January 1, 2011, the Company adopted new authoritative guidance under this ASU which provides clarification regarding the acquisition date that should be used for reporting the pro forma financial information disclosures required by Topic 805 when comparative financial statements are presented. ASU 2010-29 also requires entities to provide a description of the nature and amount of material, nonrecurring pro forma adjustments that are directly attributable to the business combination. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

FASB ASU 2011-01, “Deferral of the Effective Date of Disclosures about Troubled Debt Restructurings in Update No. 2010-20” In January 2011, the FASB issued ASU 2011-01, which temporarily delays the effective date of the disclosures about troubled debt restructurings in ASU 2010-20. The delay is intended to allow the Board time to complete its deliberations on what constitutes a troubled debt restructuring. The effective date of the new disclosures about troubled debt restructurings for public entities and the guidance for determining what constitutes a troubled debt restructuring will then be coordinated.

FASB ASU 2011-02, “Receivables (Topic 310) - A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring” In April 2011, the FASB issued ASU 2011-02, which provides clarification on whether a restructuring constitutes a troubled debt restricting and also clarifies the guidance on a creditor’s evaluation of whether it has granted a concession to the debtor and if the debtor is experiencing financial difficulties. This ASU is effective for interim and annual periods beginning on or after June 15, 2011. The Company believes this ASU will not have a material impact on the Company's consolidated financial statements.

FASB ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” In May 2011, the FASB issued ASU 2011-04. The ASU is the result of joint efforts by the FASB and IASB to develop a single, converged fair value framework on how (not when) to measure fair value and on what disclosures to provide about fair value measurements. The amended guidance changes several aspects of the fair value measurement guidance in FASB Accounting Standards Codification 820 “Fair Value Measurement” including the following provisions:

• Application of the concepts of highest and best use and valuation premise

• Introduction of a option to measure groups of offsetting assets and liabilities on a net basis

• Incorporation of certain premiums and discounts in fair value measurements

• Measurement of the fair value of certain instruments classified in shareholders' equity

56

In addition, the amended guidance includes several new fair value disclosure requirements, including information about valuation techniques and unobservable inputs used in Level 3 fair value measurements and a narrative description of Level 3 measurements' sensitivity to changes in unobservable inputs. This ASU is effective for the years beginning after December 15, 2011. The Company believes this ASU will not have a material impact on the Company's consolidated financial statements.

FASB ASU 2011-05, “Presentation of Comprehensive Income" In June 2011, the FASB issued ASU 2011-05 which amends Topic 220, Comprehensive Income by eliminating the option to present components of other comprehensive income (OCI) in the statement of stockholders' equity. This new guidance requires entities to present all nonowner changes in stockholders' equity either as a single continuous statement of comprehensive income or as two separate but consecutive statements. This ASU also requires entities to present all reclassification adjustments from OCI to net income on the face of the statement of comprehensive income. This ASU is effective for the years beginning after December 15, 2011. The Company believes this ASU will not have a material impact on the Company's consolidated financial statements.

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.

Market risk arises from exposure to changes in interest rates and other relevant market rate or price risk. The Company faces market risk in the form of interest rate risk through transactions other than trading activities. Market risk from these activities, in the form of interest rate risk, is measured and managed through a number of methods. The Company uses financial modeling techniques to measure interest rate risk. These techniques measure the sensitivity of future earnings due to changing interest rate environments. Guidelines established by the Bank’s Asset/Liability Management Committee and approved by the Bank’s Board of Directors are used to monitor exposure of earnings at risk. General interest rate movements are used to develop sensitivity as the Company feels it has no primary exposure to a specific point on the yield curve. These limits are based on the Company’s exposure to a 100 basis points and 200 basis points immediate and sustained parallel rate move, either upward or downward. In today’s low interest rate environment, the Company also monitors its exposure to immediate and sustained parallel rate increases of 300 basis points and 400 basis points.

Interest rate simulations for June 30, 2011 demonstrate that a rising rate environment will have a positive impact on net interest income.

57

The following table represents the Company’s estimated interest rate sensitivity and periodic and cumulative gap positions calculated as of June 30, 2011.

ITEM 4: CONTROLS AND PROCEDURES

Restatement of Prior Period Financial Statements Filed

In January 2012, while converting to a new system designed to address the complex accounting requirements of acquired loans under ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality”, the Company discovered an error in its process used to record income on these loans. Both interest income and the carrying value of the acquired loans were overstated. The error affects income reported on all loans acquired in FDIC assisted transactions since December 2009. On January 20, 2012, the Audit Committee of the Board of Directors of the Company and management determined that previously issued consolidated financial statements for the quarter and period ended June 30, 2011 should no longer be relied upon and should be restated.

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 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, 2011, in conjunction with the filing of our original Form 10-Q in August 2011. Based on that evaluation, the CEO and CFO concluded that the Company's disclosure controls and procedures were effective to ensure that information required to be disclosed in the Company's periodic SEC filings is processed, recorded, summarized and reported within the time periods specified in the SEC's rules and forms.

58

Subsequent to the evaluation made in connection with the Original Filing and in connection with the restatement and the filing of this Form 10-Q/A, management, including our CEO and CFO, re-evaluated the effectiveness of the design and operation of our disclosure controls and procedures and concluded that there was a material weakness in our internal control over financial reporting related to the Company's acquired loan portfolio as of June 30, 2011.

Specifically, the controls over the accounting entries of acquired loans were improperly designed and were not effective in capturing the accuracy of the resulting yield related to these loans. The controls that had been in place focused primarily on the calculation and accounting of the accretable and non-accretable yields under ASC 310-30. The controls were not effective in recording the accounting entry required to reverse the contractual interest calculated by the Company's loan servicing subsystem.

Based on this re-evaluation and including consideration of the material weakness described above, management has concluded that the Company’s disclosure controls and procedures were not effective as of June 30, 2011.

Changes to Internal Control Over Financial Reporting

There have not been any changes in our internal control over financial reporting during the quarter ended June 30, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1: LEGAL PROCEEDINGS

The following information supplements the discussion in Part I, Item 3 “Legal Proceedings” in the Company’s Annual Report on Form 10-K/A for the fiscal year ended December 31, 2010, and as updated by the Company's Quarterly Report on Form 10-Q/A for the quarter ended March 31, 2011:

Distinctive Notes

The Bank, along with other co-defendants has been named as a defendant in two lawsuits filed by persons alleging to be clients of the Bank’s Trust division who invested in promissory notes (the "Distinctive Notes") issued by Distinctive Properties (UK) Limited (“Distinctive Properties”), a company involved in the purchase and development of real estate in the United Kingdom. The Company is unable to estimate a reasonably possible loss for the cases described above because the proceedings are in early stages and there are significant factual issues to be determined and resolved. The Company denies Plaintiffs’ allegations and intends to vigorously defend the lawsuits.

Rosemann, et al. v. Martin Sigillito, et al. 

In one of the lawsuits, the plaintiffs allege that the investments in the Distinctive Notes were part of a multi-million dollar Ponzi scheme. Plaintiffs allege to hold such promissory notes in accounts with the Trust division and that, among other things, the Bank was negligent, breached its fiduciary duties and breached its contracts. Plaintiffs also allege that the Bank violated the Racketeer Influenced and Corrupt Organizations Act (“RICO”). Plaintiffs, in the aggregate, are seeking damages from defendants, including the Bank, of approximately $26.0 million as well as their costs and attorneys’ fees and trebled damages under RICO.

On June 6, 2011, the Bank filed a Motion to Dismiss the Complaint. On July 1, 2011, the United States moved to intervene in the case for the purpose of seeking a stay of the case pending completion of its criminal case against two of the individual defendants. If the stay is granted, all discovery and other activity in our case (including any rulings on the pending motions to dismiss) may be put on hold for the duration of such criminal proceedings.

BJD, LLC and Barbara Dunning v. Enterprise Bank & Trust, et. al.

The Bank has also been named as a defendant in this case, relating to BJD’s investment in the Distinctive Notes. Plaintiffs allege that the Bank, and the other defendants breached their fiduciary duties and were negligent in allowing plaintiffs to invest in the Distinctive Notes because the loan program was allegedly never funded and the assets of the borrower did not exist or were overvalued. Plaintiffs are seeking approximately $800,000 in damages, 9% interest, punitive damages, attorneys’ fees and costs. On June 16, 2011, the Bank filed a motion to compel arbitration and to stay the case. This motion is pending.

Other

As discussed in Note 7 - Commitments and Contingencies, subsequent to the Original filing, the Company was named as a defendant in a lawsuit arising from the Restatement. See Note 7 for more information concerning such subsequently filed lawsuit and the possible effects on our business.

ITEM 1A: RISK FACTORS

Please see the cautionary language regarding forward-looking statements in the introduction to Item 2 of Part I of this Report on Form 10-Q/A, Part I - Item 1A of our Report on Form 10-K/A for the fiscal year ended December 31, 2010, and and Part II - Item 1A of our Quarterly Report on Form 10-Q/A for the quarter ended March 31, 2011 for information regarding risk factors.

ITEM 5: OTHER INFORMATION

60

On July 29, 2011, Anne St. Peter tendered her resignation from the Board of Directors of Enterprise Financial Services Corp (the “Company”), which was effective immediately. Ms. St. Peter was elected to the Board on July 14, 2011. Prior to her resignation, Ms. St. Peter did not attend any meetings of the Board or any Board committee, and did not participate in actions taken by the Board. Ms. St. Peter did not resign as a result of any disagreement with the Company on any matter relating to the Company's operations, policies or practices. Ms. St. Peter resigned at the request of the Audit Committee of the Board due to a business relationship with an affiliate of the Company's independent registered public accountant, Deloitte & Touche LLP, which the Audit Committee of the Board believed could have affected Deloitte's independence had she served in a Board member capacity.

EARNINGS (LOSS) PER SHARE [Abstract]

Earnings Per Share [Text Block]

EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per common share data is calculated by dividing net income (loss) available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) 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 securities related to the issuance of 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)	2011			2010			2011			2010
Net income (loss) as reported	$	8,273		$	577		$	12,385		$	(2,614	)
Preferred stock dividend	(438		)	(436		)	(875		)	(875		)

Net income (loss) available to common shareholders	$	7,643		$	(38	)	$	11,129		$	(3,841	)
Impact of assumed conversions
Interest on 9% convertible trust preferred securities, net of income tax	371			—			742			—
Net income (loss) available to common shareholders and assumed conversions	$	8,014		$	(38	)	$	11,871		$	(3,841	)
Weighted average common shares outstanding	17,140			14,853			15,601			14,637
Incremental shares from assumed conversions of convertible trust preferred securities	1,439			—			1,439			—
Additional dilutive common stock equivalents	23			2			20			—
Diluted common shares outstanding	18,602			14,855			17,060			14,637
Basic earnings (loss) per common share:	$	0.45		$	—		$	0.71		$	(0.26	)
Diluted earnings (loss) per common share:	$	0.43		$	—		$	0.70		$	(0.26	)

For the three months ended June 30, 2011 and 2010, there were 0.5 million and 2.2 million of weighted average common stock equivalents excluded from the per share calculations because their effect was anti-dilutive. For the six months ended June 30, 2011 and 2010, there were 0.6 million and 2.3 million of weighted average common stock equivalents excluded from the per share calculations because their effect was anti-dilutive. In addition, at June 30, 2011 and 2010, the Company had outstanding warrants issued to the United States Treasury under the U.S. Treasury Capital Purchase Program to purchase 0.3 million shares of common stock which were excluded from the per common share calculation because their effect was also anti-dilutive.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

Significant Accounting Policies [Text Block]

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”).

On January 7, 2011, the Bank entered into a purchase and assumption agreement with the Federal Deposit Insurance Corporation (“FDIC”) and acquired certain assets and assumed certain liabilities of Legacy Bank, a full service community bank that was headquartered in Scottsdale, Arizona. For more information on this transaction, see Note 3 - Acquisitions in this report.

On June 24, 2011, the Bank entered into a purchase and assumption agreement with BankLiberty of Liberty, Missouri. Pursuant to the agreement, the Bank expects to purchase certain furniture and equipment, leasehold improvements and assume certain deposit liabilities associated with the BankLiberty branch located at 11401 Olive Boulevard, in the St. Louis suburb of Creve Coeur, Missouri. See Note 3 - Acquisitions for more information.

Operating results for the six months ended June 30, 2011 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2011. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2010.

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.

Approximately $4.8 million in changes to Other Assets in the Consolidated Statement of Cash Flows as of June 30, 2010 have been reclassified from Operating Activities to Investing Activities to conform with the 2011presentation. This reclassification did not result in any changes to previously reported net income or stockholders' equity.

• 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. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions. Through June 30, 2011, Level 3 securities available for sale include three Auction Rate Securities and a municipal bond issued by a school district.

• 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, 2011, of the $57.1 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $29.2 million were carried at fair value. The remaining $27.9 million of state tax credits were accounted for at cost.

The fair value of the state tax credits carried at fair value increased $198,000 for the quarter ended June 30, 2011 compared to a $1.1 million increase for the same period in 2010. These fair value changes are included in Gain on State tax credits, net in the condensed consolidated statements of operations.

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 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. Assuming that 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 fair value 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 defined as 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. 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 as of June 30, 2011.

• Purchases, sales, issuances and settlements, net. There were no purchases of Level 3 financial instruments during the quarter ended June 30, 2011. Sales of Level 3 instruments are shown in the table below.

• Transfers in and/or out of Level 3. The transfer out of Level 3 is related to two newly issued mortgage-backed securities purchased in the fourth quarter of 2010 which were originally priced using Level 3 assumptions. In the first quarter of 2011, a third party pricing service became available.

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, 2011.

(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. Fair values for impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. Other real estate owned is adjusted to fair value upon foreclosure of the underlying loan. 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. Certain state tax credits are reported at cost.

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, 2011 and December 31, 2010.

Segment Reporting Disclosure [Text Block]

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 Wealth Management 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 consulting on management compensation, 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 Corporate segment’s principal activities include the direct ownership of the Company’s banking subsidiary and the issuance of debt and equity. Its principal source of liquidity is dividends from its subsidiaries and stock option exercises.

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 three 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, 2011 and December 31, 2010, 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 carrying value of $216.9 million and $249.6 million at June 30, 2011 and December 31, 2010, 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, 2011, 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 4 years.

The unrealized losses at both June 30, 2011 and December 31, 2010, were 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, 2011, 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:

Restatement

6 Months Ended

Jun. 30, 2011

RESTATEMENT [Abstract]

Accounting Changes and Error Corrections [Text Block]

RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS

Background of the Restatement

In January 2012, while converting to a new system designed to address the complex accounting requirements of acquired loans under Accounting Standards Codification ("ASC") Topic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality”, the Company discovered an error in its process used to record income on these loans. ASC 310-30 is utilized to account for the loans acquired by the Company under loss sharing agreements with the Federal Deposit Insurance Corporation (the “FDIC”). Under ASC 310-30, these acquired loans are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the "accretable yield", is recognized as interest income on a level-yield method over the life of the loans. In accounting for income from the acquired loans, the Company recorded both the accretable yield and contractually required interest payments. The Company should not have recognized the contractually required interest payments. As a result, both interest income and the carrying value of the acquired loans were overstated. This affected income reported on the loans acquired in FDIC assisted transactions since December 2009.

Other Adjustments

In addition to the adjustments relating to the acquired loan contractual interest described above, the Company has corrected other errors that had been previously identified but not corrected because they were not material, individually or in the aggregate, to the consolidated financial results. These items included changes in accrual estimates and financial statement reclassifications. Adjustments, identified subsequent to the date of the Original Filing date, have also been made to the preliminary fair values of assets acquired and liabilities assumed for the Company's FDIC-assisted transactions.

The following tables present the impact of the restatement on the Company's previously issued unaudited interim Consolidated Statement of Operations for the three and six months ended June 30, 2011 and 2010, unaudited interim Consolidated Balance Sheet as of June 30, 2011 and unaudited interim Consolidated Statement of Cash Flows as of June 30, 2011 and 2010.

DERIVATIVE FINANCIAL INSTRUMENTS [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

DERIVATIVE FINANCIAL INSTRUMENTS

The Company is a party to various derivative financial instruments that are used in the normal course of business to meet the needs of its clients and as part of its risk management activities. These instruments include interest rate swaps and option contracts. The Company does not enter into derivative financial instruments for trading or speculative purposes.

Interest rate swap contracts involve the exchange of fixed and floating rate interest payment obligations without the exchange of the underlying principal amounts. The Company enters into interest rate swap contracts on behalf of its clients and also utilizes such contracts to reduce or eliminate the exposure to changes in the cash flows or fair value of hedged assets or liabilities due to changes in interest rates. Interest rate option contracts consist of caps and provide for the transfer or reduction of interest rate risk in exchange for a fee.

All derivative financial instruments, whether designated as hedges or not, are recorded on the consolidated balance sheet at fair value within Other assets or Other liabilities. The accounting for changes in the fair value of a derivative in the consolidated statement of operations depends on whether the contract has been designated as a hedge and qualifies for hedge accounting. At June 30, 2011 and December 31, 2010, the Company did not have any derivatives designated as cash flow or fair value hedges.

Using derivative instruments means assuming counterparty credit risk. Counterparty credit risk relates to the loss the Company could incur if a counterparty were to default on a derivative contract. Notional amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance sheet. They are used merely to express the volume of this activity. The overall credit risk and exposure to individual counterparties is monitored. The Company does not anticipate nonperformance by any counterparties. The amount of counterparty credit exposure is the unrealized gains, if any, on such derivative contracts. At June 30, 2011, the Company had pledged cash of $1.5 million and accepted pledged securities of $2.8 million as collateral in connection with our interest rate swap agreements. At December 31, 2010, the Company had accepted cash of $530,000, pledged cash of $1.5 million, and accepted pledged securities of $2.2 million as collateral in connection with our interest rate swap agreements.

Risk Management Instruments. The Company enters into certain derivative contracts to economically hedge state tax credits and certain loans.

• Economic hedge of state tax credits. In November 2008, the Company paid $2.1 million to enter into a series of interest rate caps in order to economically hedge changes in fair value of the State tax credits held for sale. In February 2010, the Company paid $751,000 for an additional series of interest rate caps. See Note 10—Fair Value Measurements for further discussion of the fair value of the state tax credits.

• Economic hedge of prime based loans. Previously, the Company had two outstanding interest rate swap agreements whereby the Company paid a variable rate of interest equivalent to the prime rate and received a fixed rate of interest. The swaps were designed to hedge the cash flows associated with a portion of prime based loans and had been designated as cash flow hedges. However, in December 2008, due to a variable rate differential, the Company concluded the cash flow hedges would not be prospectively effective and the hedges were dedesignated. The swaps were terminated in February 2009. The unrealized gain prior to dedesignation was included in Accumulated other comprehensive income and is being amortized over the expected life of the related loans. At June 30, 2011, the amount remaining in Accumulated other comprehensive income is $47,000. For the three months ended June 30, 2011 and 2010, $44,000 and $62,000 was reclassified into Miscellaneous income, respectively. For the six months ended June 30, 2011 and 2010, $88,000 and $124,000 was reclassified into Miscellaneous income, respectively. The Company expects to reclassify $74,000 of remaining derivative gains from Accumulated other comprehensive income and deferred taxes to earnings over the next five months.

The table below summarizes the notional amounts and fair values of the derivative instruments used to manage risk.

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.

There was one loan over 90 days past due and still accruing interest at June 30, 2011. If interest on impaired loans would have been accrued based upon the original contractual terms, such income would have been $891,000 and $1.5 million, for the three and six months ended June 30, 2011, respectively. The cash amount collected and recognized as interest income on impaired loans was $74,000 and $203,000 for the three and six months ended June 30, 2011, respectively. The amount recognized as interest income on impaired loans continuing to accrue interest was $62,000 and $213,000 for the three and six months ended June 30, 2011, respectively. At June 30, 2011, there were $1.6 million of unadvanced commitments on impaired loans. Other Liabilities include approximately $321,000 for estimated losses attributable to the unadvanced commitments on impaired loans.

The recorded investment in impaired loans by category at June 30, 2011 and December 31, 2010 is as follows:

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. This analysis is performed on a quarterly basis. 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 circumstances where the company is starting to reverse a negative trend or condition, or have recently been upgraded from a 7, 8, or 9 rating.

• Grade 7 – Watch credits are companies that have experienced financial setback of a nature that are not determined to be severe or influence ‘ongoing concern’ expectations. Borrowers within this category are expected to turnaround within a 12-month period of time. Although possible, no loss is anticipated, due to strong collateral and/or guarantor support.

• Grade 8 – Substandard credits will include those companies 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. Borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on non-accrual.

Acquired loans are also subject to the Company’s internal and external credit review and are risk rated using the same criteria as loans originated by the Company. However, risk ratings are not always a clear indicator of the Company's losses on acquired loans as a majority of the losses are recoverable from the FDIC under the loss-sharing agreements.

The recorded investment by risk category of the loans by portfolio class and category at June 30, 2011, which is based upon the most recent analysis performed, and December 31, 2010 is as follows:

Portfolio loans covered under FDIC loss share

Purchased loans acquired in a business combination, including loans purchased in our FDIC-assisted transactions, are recorded at estimated fair value on their purchase date without a carryover of the related allowance for loan losses. Purchased credit-impaired loans are loans that have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the purchase date may include factors such as past due and non-accrual status. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable yield. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges or a reclassification of the difference from non-accretable to accretable with a positive impact on interest income. Further, any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows.

Changes in the accretable yield for purchased loans were as follows for the six months ended June 30, 2011 and 2010:

(in thousands)	June 30, 2011			June 30, 2010
Balance at beginning of period	$	46,460		$	3,708
Additions	10,875			—
Accretion	(11,433		)	(494		)
Balance at end of period	$	45,902		$	3,214

Outstanding balances on purchased loans from the FDIC were $260.8 million as of June 30, 2011 and $219.5 million at December 31, 2010, respectively. In the second quarter of 2011, the Bank received payments of $10.9 million for loss share claims under the terms of the FDIC loss share agreements.

Legacy acquisition

The following table presents information regarding the contractually required payments receivable, the cash flows expected to be collected, and the estimated fair value of the loans acquired in the Legacy acquisition, at the closing date of the transaction:

(In thousands)	January 7, 2011 Purchased  Credit-Impaired Loans
Contractually required payments (principal and interest):	$	106,286
Cash flows expected to be collected (principal and interest):	84,089
Fair value of loans acquired:	73,214

These amounts were determined based upon the estimated remaining life of the underlying loans, which includes the effects of estimated prepayments. The majority of the purchased credit-impaired loans were valued based on the liquidation value of the underlying collateral. There was no allowance for credit losses on purchased loans related to FDIC-assisted transactions at June 30, 2011.

The determination of the initial fair value of loans and other real estate acquired in the transaction and the initial fair value of the related FDIC loss share receivable involve a high degree of judgment and complexity. The carrying value of the acquired loans and other real estate and the FDIC indemnification asset reflect management’s best estimate of the fair value of each of these assets as of the date of acquisition. However, the amount that the Bank realizes on these assets could differ materially from the carrying value reflected in these financial statements, based upon the timing and amount of collections on the acquired loans in future periods. To the extent the actual values realized for the acquired loans are different from the estimate, the FDIC loss share receivable will generally be affected in an offsetting manner due to the indemnification obligations of the FDIC, thus limiting the Bank’s loss exposure.

COMMITMENTS AND CONTINGENCIES [Abstract]

Commitments and Contingencies Disclosure [Text Block]

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 in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit 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, 2011 there were $1.6 million of unadvanced commitments on impaired loans. Other liabilities include approximately $321,000 for estimated losses attributable to the unadvanced commitments on impaired loans.

The contractual amounts of off-balance-sheet financial instruments as of June 30, 2011 and December 31, 2010 are as follows:

(in thousands)	June 30, 2011		December 31, 2010
Commitments to extend credit	$	445,307	$	429,411
Standby letters of credit	44,598		42,113

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 and may require payment of a fee. Of the total commitments to extend credit at June 30, 2011 and December 31, 2010, approximately $72.1 million and $67.0 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon, 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. 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 letters of credit is essentially the same as the risk involved in extending loans to customers. The approximate remaining term of standby letters of credit range from 6 months to 5 years at June 30, 2011.

Contingencies

The Bank, along with other co-defendants has been named as a defendant in two lawsuits filed by persons alleging to be clients of the Bank’s Trust division who invested in promissory notes issued by Distinctive Properties (UK) Limited (“Distinctive Properties”), a company involved in the purchase and development of real estate in the United Kingdom. Plaintiffs allege that the promissory notes were part of a multi-million dollar Ponzi scheme. Plaintiffs allege to hold such promissory notes in accounts with the Trust division and that, among other things, the Bank was negligent, breached its fiduciary duties and breached its contracts. Plaintiffs also allege that the Bank violated the Racketeer Influenced and Corrupt Organizations Act (“RICO”). Plaintiffs, in the aggregate, are seeking damages from defendants, including the Bank, of approximately $27.0 million as well as their costs and attorneys’ fees and trebled damages under RICO. The Company is unable to estimate a reasonably possible loss for the cases described above because the proceedings are in early stages and there are significant factual issues to be determined and resolved. The Company denies Plaintiffs’ allegations and intends to vigorously defend the lawsuits.

The following litigation was filed subsequent to the Quarterly Report on Form 10-Q for the quarter ended June 30, 2011, which was filed with the Securities and Exchange Commission (“SEC”) on August 3, 2011. On April 10, 2012, a putative class action was filed in the United States District Court for the Eastern District of Missouri captioned William Mark Scott v. Enterprise Financial Services Corp, Peter F. Benoist, and Frank H. Sanfilippo. The complaint asserts claims for violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of a putative class of purchasers of the Company's stock between April 20, 2010 and January 25, 2012, inclusive. The complaint alleges, among other things, that defendants allegedly made false and misleading statements and allegedly "failed to disclose that the Company was improperly recording income on loans covered under loss share agreements with the FDIC" and that, as a result, "the Company's financial statements were materially false and misleading at all relevant times." The action seeks unspecified damages and costs and expenses. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuit.

ACQUISITIONS AND DIVESTITURES [Abstract]

Mergers, Acquisitions and Dispositions Disclosures [Text Block]

ACQUISITIONS

Acquisition of Legacy Bank

On January 7, 2011, the Bank entered into a purchase and assumption agreement with the FDIC and acquired certain assets and assumed certain liabilities of Legacy Bank (“Legacy”), a full service community bank that was headquartered in Scottsdale, Arizona. The acquisition consisted of tangible assets with estimated fair values of approximately $128.0 million and tangible liabilities with estimated fair values of approximately $130.4 million. The Bank acquired the assets at a discount of 7.6% and approximately $43.5 million of the deposits were assumed at a premium of 1%. The Bank also acquired approximately $55.6 million of discretionary and $13.6 million of non-discretionary trust assets.

As part of the acquisition, the Company provided the FDIC with a Value Appreciation Instrument (“VAI”) whereby 372,500 units were awarded to the FDIC at an exercise price of $10.63 per unit. The units were exercisable at any time from January 14, 2011 until January 6, 2012. The FDIC exercised the units on January 20, 2011 at a settlement price of $11.8444 per unit. A cash payment of $452,364 was made to the FDIC on January 21, 2011.

In connection with the acquisition, the Bank also entered into a loss share agreement whereby the FDIC will reimburse the Bank for 80% of all losses incurred on certain loans and other real estate covered under the agreement (“Covered Assets”). The loss share agreement is subject to the servicing procedures as specified in the agreement with the FDIC.

The reimbursable losses from the FDIC are based on the book value of the Covered Assets as determined by the FDIC as of the date of the acquisition. A majority of these loans were valued based on the liquidation value of the underlying collateral because the future cash flows are primarily based on the liquidation of underlying collateral. The expected reimbursements under the loss share agreement were recorded as a FDIC loss share receivable at their estimated fair value.

The loans and other real estate acquired are recorded at estimated fair value. As such, there was no allowance for credit losses established related to the acquired loans at January 7, 2011 and no carryover of the related allowance from Legacy. The loans are accounted for in accordance with guidance for certain loans acquired in a transfer, when the loans have evidence of credit deterioration and it is probable at the date of acquisition that the acquirer will not collect all contractually required principal and interest payments. The difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges and an adjustment in accretable yield, which will have a positive impact on interest income.

The table below summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition. The table includes adjustments subsequent to the date of the Original Filing on Form 10-Q. These fair value estimates are considered preliminary, and are subject to change for up to one year after the closing date of the acquisition as additional information relative to closing date fair values becomes available.

Management concluded that it is impracticable to present pro forma financial results due to the lack of documentation and objective information about significant estimates and management’s intent in prior periods.

Acquisition of BankLiberty branch

On June 24, 2011, the Bank entered into a purchase and assumption agreement with BankLiberty in Liberty, Missouri. Pursuant to the agreement, the Bank expects to purchase certain furniture and equipment, leasehold improvements and assume certain deposit liabilities associated with the BankLiberty branch located at 11401 Olive Boulevard, in the St. Louis suburb of Creve Coeur, Missouri.
