Notes to Condensed Consolidated Financial Statements (Unaudited)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by Enterprise Financial Services Corp (the “Company” or “Enterprise”) in the preparation of the condensed consolidated financial statements are summarized below:

Business and Consolidation

Enterprise is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers located in the St. Louis, Kansas City and Phoenix metropolitan markets through its banking subsidiary, Enterprise Bank & Trust (the “Bank”).

Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2012. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

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. Certain 2011 amounts in the consolidated financial statements have been reclassified to conform to the 2012 presentation. These reclassifications have no effect on Net income or Shareholders' equity as previously reported.

NOTE 2 - EARNINGS PER SHARE

Basic earnings per common share data is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Common shares outstanding include common stock and restricted stock awards where recipients have satisfied the vesting terms. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method for convertible 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 September 30,						Nine months ended September 30,

For the three months ended September 30, 2012 and 2011, the amount of common stock equivalents that were excluded from the earnings per share calculations because their effect was anti-dilutive was 1.0 million (including 324,074 common stock warrants) and 744,632 common stock equivalents (including 324,074 common stock warrants), respectively. For the nine months ended September 30, 2012 and 2011, the amount of common stock equivalents that were excluded from the earnings per share calculations because their effect was anti-dilutive was 1.0 million (including 324,074 common stock warrants) and 888,821 (including 324,074 common stock warrants), respectively.

At September 30, 2012, and December 31, 2011, there were no holdings of securities of any one issuer in an amount greater than 10% of shareholders’ equity, other than the U.S. government agencies and sponsored enterprises. The residential mortgage-backed securities are all issued by U.S. government sponsored enterprises. Available for sale securities having a fair value of $271.8 million and $287.8 million at September 30, 2012, and December 31, 2011, 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 September 30, 2012, 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 3 years.

The unrealized losses at both September 30, 2012, and December 31, 2011, were primarily attributable to changes in market interest rates since the securities were purchased. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security and (5) the intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. At September 30, 2012, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.

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

The Company grants commercial, residential, and consumer loans primarily in the St. Louis, Kansas City and Phoenix metropolitan areas. The Company has a diversified loan portfolio, with no particular concentration of credit in any one economic sector; however, a substantial portion of the portfolio is concentrated in and secured by real estate. The ability of the Company’s borrowers to honor their contractual obligations is partially dependent upon the local economy and its effect on the real estate market.

The 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.

15

• 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.

NOTE 5 - PORTFOLIO LOANS COVERED BY LOSS SHARE ("Covered loans")

Purchased loans acquired 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, prospectively. 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. Acquired loans that have common risk characteristics are aggregated into pools. The Company remeasures contractual and expected cash flows, at the pool-level, on a quarterly basis.

16

Inputs to the determination of expected cash flows include contractual cash flows, cumulative default and prepayment data as well as loss severity and recovery lag information. Cumulative default and prepayment data are calculated via a transition matrix. The transition matrix is a matrix of probability values that specifies the probability of a loan pool transitioning into a loss given its delinquency state (e.g. 0-30 days past due, 31 to 60 days, etc.) at the remeasurement date. Loss severity factors are based upon industry data along with actual charge-off data within the loan pools and recovery lags are based upon industry data along with experience with the collateral within the loan pools.

Covered 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.

Below is a summary of Covered loans by category at September 30, 2012, and December 31, 2011:

The accretable yield is accreted into interest income over the estimated life of the acquired loans using the effective

yield method. Other adjustments to the accretable yield include changes in the estimated remaining life of the acquired loans, changes in expected cash flows and changes of indices for acquired loans with variable interest rates.

Changes in the accretable yield for purchased loans were as follows for the nine months ended September 30, 2012, and 2011:

(in thousands)	September 30, 2012			September 30, 2011
Balance at beginning of period	$	63,335		$	46,460

Balance at end of period	$	95,445		$	42,435

Other changes in the accretable yield include the impact of cash flow timing estimates, changes in variable interest rates, and other non-credit related adjustments. For the three months ended and nine months ended September 30, 2012, the Bank received payments of $15.2 million and $85.2 million, respectively, for loss share claims under the terms of the FDIC shared-loss agreements.

NOTE 6 - COMMITMENTS AND CONTINGENCIES

The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

The Company’s extent of involvement and maximum potential exposure to credit loss under commitments to extend credit and standby letters of credit in the event of nonperformance by the other party to the financial instrument is represented by the contractual amount of these instruments.

The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At September 30, 2012, there were $543,000 of unadvanced commitments on impaired loans. Other liabilities include approximately $98,000 for estimated losses attributable to the unadvanced commitments on impaired loans.

The contractual amounts of off-balance-sheet financial instruments as of September 30, 2012, and December 31, 2011, are as follows:

(in thousands)	September 30, 2012		December 31, 2011
Commitments to extend credit	$	724,517	$	547,657
Standby letters of credit	43,383		43,973

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at September 30, 2012, and December 31, 2011, approximately $66.3 million and $75.7 million, respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate. Included in the September 30, 2012 commitments to extend credit are $106 million of lines with significant usage restrictions.

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 September 30, 2012.

Contingencies

The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Other than those described below, management believes that there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

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

19

in the United Kingdom. The Company is unable to estimate a reasonably possible loss for the cases described below because the proceedings are in early stages and there are significant factual issues to be determined and resolved in each case. 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”). Upon the Bank's motion, the Court dismissed the plaintiffs' claim that the Bank violated its fiduciary duties. Plaintiffs, in the aggregate, are seeking damages from defendants, including the Bank, in excess of $44.0 million as well as their costs and attorneys’ fees and trebled damages under RICO.

The case was stayed while criminal proceedings against Sigillito were completed. After a four week trial, Sigillito was found guilty of 20 counts of wire fraud, mail fraud, conspiracy, and money laundering. Following the verdict, the judge lifted the stay and set the case for a four week jury trial starting August 26, 2013. Discovery is currently proceeding.

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. Like Rosemann, this case was stayed while the Sigillito criminal case was pending. The court has now granted the Bank's motion to compel arbitration and stay proceedings. Arbitration proceedings are not yet underway.

William Mark Scott v. Enterprise Financial Services Corp, et. al.

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 made false and misleading statements and "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 is unable to estimate a reasonably possible loss for the case because the proceeding is in an early stage and there are significant factual issues to be determined and resolved. The Company denies plaintiffs’ allegations and intends to vigorously defend the lawsuit.

NOTE 7 - 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 and foreign exchange forward 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. Foreign exchange forward contracts are agreements between two parties to exchange a specified amount of one currency for another currency at a specified foreign exchange

20

rate on a future date. The Company enters into foreign exchange forward contracts with their clients and enters into an offsetting foreign exchange contract with established financial institution counterparties.

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 September 30, 2012, and December 31, 2011, 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 along with the value of foreign exchange forward contracts. At September 30, 2012, the Company had $3.4 million of counterparty credit exposure on derivatives. At September 30, 2012, and December 31, 2011, the Company had pledged cash of $3.8 million and $2.7 million, respectively, 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 8—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. For the three months ended September 30, 2011, $44,000 was reclassified into Miscellaneous income. For the nine months ended September 30, 2011, $132,000 was reclassified into Miscellaneous income. At December 31, 2011, there were no additional amounts remaining in Accumulated other comprehensive income to be reclassified into operations.

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

Client-Related Derivative Instruments. As an accommodation to certain customers, the Company enters into interest rate swaps to economically hedge changes in fair value of certain loans. During the second quarter of 2012, the Company entered into foreign exchange forward contracts with clients and entered into offsetting foreign exchange forward contracts with established financial institution counterparties. The table below summarizes the notional amounts and fair values of the client-related derivative instruments.

• 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. At September 30, 2012, Level 3 securities available for sale consist primarily of three Auction Rate Securities.

• 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 September 30, 2012, of the $65.9 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $25.1 million were carried at fair value. The remaining $40.8 million of state tax credits were accounted for at cost.

The fair value of the state tax credits carried at fair value increased $257,000 for the quarter ended September 30, 2012 compared to $975,000 for the same period in 2011. 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 Missouri state residents who buy these credits and from local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine the fair value.

The fair value measurement is calculated using an internal valuation model with observable market data including discounted cash flows based upon the terms and conditions of the tax credits. Assuming that the

23

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. An increase in the discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits. Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level 3 assets.

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

Level 3 financial instruments

The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis as of September 30, 2012.

• Purchases, sales, issuances and settlements, net. There were no Level 3 purchases during the quarter ended September 30, 2012.

• Transfers in and/or out of Level 3. The transfer out of Level 3 is related to a newly issued mortgage-backed security purchased in the fourth quarter of 2011 which was originally priced using Level 3 assumptions. In the first quarter of 2012, a third party pricing service, utilizing Level 2 assumptions, became available as more data was available on the new security.

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 September 30, 2012.

(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 September 30, 2012, and December 31, 2011.

NOTE 9 - SEGMENT REPORTING

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

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

The Banking operating segment also includes activities surrounding the assets acquired under FDIC loss share agreements. 

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.

27

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.

29

Banking Segment

• Loans - Portfolio loans totaled $2.2 billion at September 30, 2012, flat with December 31, 2011 and September 30, 2011. Loans covered under FDIC shared loss agreements ("Covered loans") were $221.4 million at September 30, 2012, a decrease of $79.2 million or 26% from December 31, 2011 and a decrease of $105.5 million or 32% from September 30, 2011. The decrease is due to principal paydowns and loans that paid off.

Portfolio loans excluding covered loans ("Noncovered loans") increased $90.1 million or 5% from December 31, 2011. Commercial & Industrial loans increased $117.2 million or 15% and Construction Real Estate loans increased $6.1 million or 4%, while Residential Real Estate loans decreased $24.1 million or 14%. Noncovered loans increased $119.2 million or 6% from September 30, 2011. Commercial and Industrial loans increased $174.3 million or 25% while Residential and Construction Real Estate loans declined $37.2 million or 11%.

For fiscal year 2012, the Company expects 6-8% growth in portfolio loans not covered by FDIC shared loss agreements, similar to 2011 results. Based on the most recent remeasurement of expected cash flows, the Company expects the average balance of Covered loans to be approximately $187 million, $131 million, and $74 million in 2013, 2014, and 2015, respectively.

See Note 4 – Portfolio Loans Not Covered by Loss Share and Note 5 – Portfolio Loans Covered by Loss Share for more information.

• Deposits – Total deposits at September 30, 2012 were $2.6 billion, a decrease of $240.4 million, or 9%, and $266.3 million, or 9%, from December 31, 2011 and September 30, 2011, respectively. The decrease is mainly due to a decline in certificates of deposit as the Company continues to force a decline through lower cost pricing. Demand deposits increased $35.6 million or 6% from December 31, 2011 and $63.8 million or 11% from September 30, 2011 while interest bearing transaction accounts decreased $72.3 million or 5% from December 31, 2011 and $42.4 million or 3% from September 30, 2011.

Reciprocal CDARS certificates were $5.5 million at September 30, 2012, a decrease of $8.9 million, or 62%, and $14 million, or 71%, from December 31, 2011 and September 30, 2011, respectively.

• Asset quality – Nonperforming loans, including troubled debt restructurings were $32.1 million at September 30, 2012, compared to $41.6 million at December 31, 2011 and $48.0 million at September 30, 2011. Nonperforming loans represented 1.61% of total Noncovered loans at September 30, 2012 versus 2.19% at December 31, 2011 and 2.57% at September 30, 2011. Excluding non-accrual loans and Covered loans, portfolio loans that were 30-89 days delinquent at September 30, 2012 remained at very low levels, representing 0.07% of the portfolio compared to 0.36% at December 31, 2011 and 0.03% at September 30, 2011.

Provision for loan losses not covered under FDIC loss share was $1.0 million in the third quarter of 2012, compared to $5.4 million in the third quarter of 2011. The decrease in the provision for loan losses in the third quarter of 2012 was due to lower levels of loan risk rating downgrades, and more favorable loss migration statistics from a year ago. See Note 4 – Portfolio Loans Not Covered by Loss Share 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 5.21% for the third quarter of 2012, compared to 4.81% for the second quarter of 2012 and 3.79% in the third quarter of 2011. For the nine month period ended September 30, 2012, the net interest rate margin was 4.79% compared to 4.04% for the same period in 2011. 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 $1.8 million in the third quarter of 2012, a decrease of $166,000, or 8%, over the linked second quarter and flat compared to September 30, 2011. See Noninterest Income in this section for more information.

Net Interest Income

Three months ended September 30, 2012 and 2011

Net interest income (on a tax equivalent basis) was $37.9 million for the three months ended September 30, 2012 compared to $27.1 million for the same period of 2011, an increase of $10.8 million, or 40%. Total interest income increased $8.7 million and total interest expense decreased $2.1 million.

Average interest-earning assets increased $55.3 million, or 2%, to $2.9 billion for the quarter ended September 30, 2012 from $2.8 billion for the quarter ended September 30, 2011. Average loans increased $94.0 million, or 4%, to $2.2 billion for the quarter ended September 30, 2012 from $2.1 billion for the quarter ended September 30, 2011. Noncovered loans increased $117.1 million while Covered loans decreased $23.1 million. Average securities increased $114.8 million or 23%, while short-term investments decreased $153.5 million or 63.0% from the third quarter of 2011. Interest income on earning assets increased $1.5 million due to higher volume and increased $7.2 million due to higher rates, for an increase of $8.7 million versus the third quarter of 2011.

For the quarter ended September 30, 2012, average interest-bearing liabilities decreased $150.9 million, or 6%, to $2.3 billion compared to $2.4 billion for the quarter ended September 30, 2011. The decrease resulted from a $175.5 million decrease in average interest-bearing deposits, offset by a $24.6 million increase in borrowed funds from customer repurchase agreements. The decrease in average interest-bearing deposits is due to a $220.4 million decrease in certificates of deposit, offset by a $3.9 million increase in average money market accounts and savings accounts, and an increase of $41.1 million in interest-bearing transaction accounts. For the third quarter of 2012, interest expense on interest-bearing liabilities decreased $1.4 million due to declining rates and $689,000 due to the impact of lower volumes, for a net decrease of $2.1 million versus the third quarter of 2011.

The tax-equivalent net interest rate margin was 5.21% for the third quarter of 2012, compared to 4.81% for the second quarter of 2012 and 3.79% in the third quarter of 2011. In the third quarter of 2012, the Covered loans yielded 26.51%

31

primarily due to cash flows on paid off loans that exceeded expectations. Absent the Covered loans, related nonearning assets, and related funding costs, the net interest rate margin was 3.42% for the third quarter of 2012 compared to 3.46% for the second quarter of 2012.

We expect the fourth quarter net interest margin to remain above 4%. We expect continued volatility in the yield on Covered loans due primarily to prepayments, and, possibly, the quarterly remeasurement of cash flows. We expect the yield on Covered loans, without the impact of prepayments, to be approximately 13% - 15% in the fourth quarter of 2012. Yields on Noncovered loans are expected to fall further in the fourth quarter and will offset lower deposit costs.

Nine months ended September 30, 2012 and 2011

Net interest income (on a tax equivalent basis) was $103.3 million for the nine months ended September 30, 2012 compared to $81.4 million for the same period of 2011, an increase of $21.9 million, or 27%. Total interest income increased $16.9 million and total interest expense decreased $5.0 million.

Average interest-earning assets increased $185.8 million, or 7%, to $2.9 billion for the nine months ended September 30, 2012 from $2.7 billion for the nine months ended September 30, 2011. Average loans increased $180.3 million, or 9%, to $2.2 billion for the nine months ended September 30, 2012 from $2.0 billion for the nine months ended September 30, 2011. Approximately $50.0 million of the increase is related to an increase in the Covered loans from the acquisition of The First National Bank of Olathe ("FNB"). Average securities increased $113.2 million or 24% while short-term investments decreased $107.7 million or 49% from the third quarter of 2011. Interest income on earning assets increased $13.1 million due to higher volume and $3.7 million due to higher rates, for an increase of $16.9 million versus the third quarter of 2011.

For the nine months ended September 30, 2012, average interest-bearing liabilities increased $38.3 million, or 2%, to $2.4 billion compared to $2.3 billion for the nine months ended September 30, 2011. The increase in average interest-bearing liabilities resulted from a $26.4 million increase in average interest-bearing deposits, due to a $114.8 million increase in average money market accounts and savings accounts, an increase of $54.5 million in interest-bearing transaction accounts, offset by a decrease of $143.0 million in certificates of deposit. For the nine months ended September 30, 2012, interest expense on interest-bearing liabilities decreased $4.3 million due to declining rates and $697,000 due to the impact of lower volumes of certificates of deposit, for a net decrease of $5.0 million versus the same period in 2011.

The tax-equivalent net interest rate margin was 4.79% for the nine months ended September 30, 2012, compared to 4.04% in the same period of 2011. The increase in the margin was primarily due to a higher yield on the Covered loans, resulting from cash flows on paid off covered loans that exceeded expectations, and lower funding costs.

Provision and Allowance for Loan Losses

The provision for loan losses not covered under FDIC loss share for the three and nine months ended September, 30 2012 was $1.0 million and $2.8 million compared to $5.4 million and $13.3 million for the comparable 2011 periods. The lower loan loss provision for the third quarter of 2012 compared to the third quarter of 2011 was due to lower levels of loan risk rating downgrades. The lower loan loss provision for the nine months ended September 30, 2012 compared to the nine months ended September 30, 2011 was due to lower levels of risk rating-downgrades, more favorable loss migration statistics from a year ago, and payoff of one specific loan which carried a $1.3 million reserve.

The Company expects the fourth quarter 2012 provision for loan losses not covered under FDIC shared loss agreements to be approximately $2 - $4 million.

35

For Covered loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the remeasurement process results in a decrease in expected cash flows, typically due to an increase in expected credit losses, impairment is recorded through provision for loan losses. The provision for loan losses on Covered loans was $10.9 million in the third quarter of 2012 compared to $2.7 million in the third quarter of 2011. The provision for loan losses in the third quarter of 2012 was partially offset through noninterest income by an increase in the FDIC loss share receivable totaling $8.7 million.

The provision expense for Covered loans in the third quarter of 2012 was a result of increases in loss estimates on certain substandard loans, degradation in the overall delinquency status of certain loan pools, and the effect of loan modifications which increased the probability of default in the remeasurement process.

Excluding the Covered loans, the allowance for loan losses was 1.72% of total loans at September 30, 2012, representing 107% of nonperforming loans. The loan loss allowance was 2.00% at December 31, 2011 representing 91% of nonperforming loans and 2.30% at September 30, 2011 representing 89% of nonperforming loans. Management believes that the allowance for loan losses is adequate to absorb inherent losses in the loan portfolio.

Excluding the Covered loans, net charge-offs in the third quarter of 2012 were $3.1 million, representing an annualized rate of 0.64% of average loans, compared to net charge-offs of $4.7 million, an annualized rate of 1.01% of average loans, in the third quarter of 2011. Approximately 30% of the net charge-offs in the third quarter of 2012 were related to Construction and Land Development loans, 43% were related to Commercial & Industrial loans, 40% were related to Commercial Real Estate loans and there were 13% net recoveries in Residential Real Estate loans.

For the nine months ended September 30, 2012, excluding the Covered loans, net charge-offs were $6.6 million, compared to net charge-offs of $13.2 million for the same period in 2011. Approximately 31% of the net charge-offs for the nine months ended September 30, 2012 were related to Construction and Land Development loans, 31% were related to Commercial & Industrial, 45% were related to Commercial Real Estate loans and there were 7% net recoveries in Residential Real Estate loans.

As noted in the second quarter, the Company has adopted a more aggressive problem asset resolution strategy designed to reduce the level of problem assets on an accelerated basis. If successful, this strategy should result in lower levels of non performing and substandard assets by year end with net charge offs (excluding covered loans) for the fourth quarter totaling up to $8 million.

Nonperforming loans

Nonperforming loans exclude Covered loans that are accounted for on a pool basis, as the pools are considered to be performing. See Note 5 – Portfolio Loans covered under loss share for more information on these loans.

Nonperforming loans, including troubled debt restructurings of $4.7 million, were $32.1 million at September 30, 2012, a decrease from $41.6 million at December 31, 2011, and $48.0 million at September 30, 2011. The decline is due to principal pay downs and loans collateralized by real estate being placed into foreclosure. The nonperforming loans are comprised of approximately 38 relationships with the largest being a $5.0 million commercial real estate loan. Five relationships comprise 44% of the nonperforming loans. Approximately 48% were located in the St. Louis market, 51% of the nonperforming loans were located in the Kansas City market, and 1% were located in the Arizona market. At September 30, 2012, there were no performing restructured loans that have been excluded from the nonperforming loan amounts.

Nonperforming loans represented 1.61% of Noncovered loans at September 30, 2012, versus 2.19% at December 31, 2011 and 2.57% at September 30, 2011.

Other real estate

Other real estate at September 30, 2012, was $31.4 million, compared to $53.7 million at December 31, 2011, and $72.6 million at September 30, 2011. Approximately 79% of the decrease from December 31, 2011 and September 30, 2011 is from Other real estate covered by FDIC shared-loss agreements. Approximately 60% of total Other real estate, or $18.8 million, is covered by FDIC shared-loss agreements.

At September 30, 2012, Other real estate was comprised of 16% residential lots, 4% completed homes, and 80% commercial real estate. Of the total Other real estate, 54%, or 39 properties, are located in the Kansas City region, 19%, or 19 properties, are located in the St. Louis region and 27%, or 20 properties, are located in the Arizona region. All Arizona Other real estate properties and 25, or $10.4 million, of the Kansas City Other real estate are covered under FDIC loss share.

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 nine months ended September 30, 2012, the Company realized a net gain of $3.2 million on the sale of other real estate and recorded these gains as part of Noninterest income.

Noninterest Income

Noninterest income decreased $894,000, or 10%, in the third quarter of 2012 compared to the third quarter of 2011. The decrease is primarily due to decreases in income related to sales of state tax credits and lower gains on the sale of investments.

For the nine months ended September 30, 2012, Noninterest income decreased $5.2 million, or 29%, from the same period in 2011. The decrease is primarily due to decreases in income related to changes in the FDIC Receivable and lower income related to the sale of state tax credits offset by increases in gains on the sale of other real estate and fee income from service charges.

• Wealth Management revenue– For the three and nine months ended September 30, 2012, Wealth Management revenue from the Trust division decreased $7,000 and increased $352,000, or 7%, over the same periods in 2011, respectively. Assets under administration were $1.6 billion at September 30, 2012, a 14% increase from September 30, 2011, due to market value increases and additional accounts from new clients.

• Service charges and other fee income–For the three and nine months ended September 30, 2012, service charges and other fee income increased $336,000 and $1.3 million, respectively, compared to the same period in 2011 due to an increase in service charges on business accounts, debit card and credit card income, and overdraft fees. The $1.3 million increase in these fees for the nine months ended September 30, 2012 is primarily due to the acquisition of FNB.

• Sale of Other real estate – For the quarter ended September 30, 2012, we sold $11.6 million of Other real estate for a gain of $739,000 which included a gain of $705,000 from Other real estate not covered by loss share agreements and a gain of $34,000 from Other real estate covered by loss share agreements. Year-to-date through September 30, 2012, we have sold $38.4 million of Other real estate for a net gain of $3.2 million which included a gain of $1.2 million from Other real estate not covered by loss share agreements and a gain of $2.0 million from other real estate covered by loss share agreements. For the year-to-date period in 2011, we sold $25.3 million of Other real estate for a net gain of $1.0 million.

• State tax credit brokerage activities– For the quarter ended September 30, 2012, the Company recorded a gain of $256,000 compared to a gain of $1.4 million in the third quarter of 2011. For the nine months ended September 30, 2012, the Company recorded a gain of $1.2 million compared to a gain of $2.5 million for the nine months ended September 30, 2011. The decrease in both periods is due to lower sales volume of client purchases of the state tax credits and lower net mark-to-market gains on those tax credits held at fair value. For more information on the fair value treatment of the state tax credits, see Note 8 – Fair Value Measurements.

• Sale of investment securities – During the first nine months of 2012, the Company realized approximately $110.9 million of proceeds on the sale of investment securities, generating a net gain of $1.2 million.

• Change in FDIC loss share receivable – Our four shared-loss agreements with the FDIC have provisions by which the FDIC is required to reimburse us for certain loan losses including up to 90 days of accrued but unpaid interest and direct expenses related to the resolution of assets incurring a loss. Generally, the agreements carry terms of five years from date of acquisition for non-single family or commercial assets and ten years from date of acquisition for single family assets. The shared loss agreements with the FDIC for the HNB and Legacy bank

40

acquisitions contain 80% loss coverage during the term of the agreements while the Valley Capital agreement provides for 95% loss coverage through the remaining term of the agreement. The shared loss agreement relative to our FNB acquisition has three tranches of losses, each with a specified loss coverage percentage. Losses up to $112.6 million are reimbursed 80% by the FDIC. Losses from $112.6 million to $148.9 million will not be reimbursed, while losses in excess of $148.9 million revert to 80% loss share reimbursement.

Projections of future losses and the timing thereof are inherently uncertain, though we do not expect to move into the 2^nd tranche of losses in the FNB agreement in the next twelve months. The fair value adjustments assigned to the related Covered loans at acquisition date encompassed anticipated losses, and as a result, the losses reported for loss sharing purposes do not correspond to income or losses reported in our financial statements. The Change in FDIC loss share receivable represents the accretion and other changes necessary to adjust the value of our FDIC loss share receivable to the estimated recoveries from the FDIC subject to the aforementioned contractual limitations of the loss sharing agreements.

Income related to changes in the FDIC loss share receivable increased $399,000 during the third quarter of 2012 compared to the same period in 2011. The increase in income related to the FDIC loss share receivable was primarily due to increases in the FDIC loss share receivable asset related to the impairment recorded in the third quarter of 2012. To correlate with the new higher projected loss amounts, the FDIC loss share receivable is increased. The increases in the FDIC loss share receivable were partially offset by reductions for loan pay offs in which the losses on the loans were less than expected along with lower loss expectations on certain loan pools. For the nine months ended September 30, 2012, the FDIC loss share receivable decreased $7.9 million primarily due to loan pay offs in which the losses on the loans were less than expected along with lower loss expectations on certain loan pools. Absent any changes based on the quarterly remeasurement process or accelerated cash flows, the Company anticipates negative accretion of $4.0 - $6.0 million in the fourth quarter of 2012.

Noninterest Expense

Noninterest expenses were $21.3 million in the third quarter of 2012, an increase of $3.0 million, or 16%, from the same quarter of 2011. The increase over the prior year period was primarily comprised of an increase of $2.1 million in salaries and benefits related to an increase in salary expense, the accrual of higher variable compensation expense and the long-term incentive plans. Other expenses increased $938,000 which included a $559,000 increase in legal and professional fees, $272,000 in marketing expenses and a $270,000 increase related to deferred compensation. These increases in expense were partially offset by a decrease in loan related legal expense and other real estate expenses of $389,000 primarily due to lower writedowns and other expenses incurred on other real estate.

For the nine months ended September 30, 2012, non interest expenses were $64.1 million, an increase of $9.8 million million or 18% from the nine months ended September 30, 2011. The increase over the prior year period was primarily comprised of a $6.7 million increase in salaries and benefits due to an increase in salary expense, the accrual of higher variable compensation expense and the long-term incentive plans. Other expenses increased $4.4 million, which included a $1.7 million increase in legal and professional fees, a $951,000 increase in amortization of intangible assets

from the acquisition of FNB and $456,000 in marketing expenses. Loan legal and other real estate expense decreased $2.1 million due to decrease in writedowns and other expenses incurred on other real estate.

The Company's efficiency ratio, which measures noninterest expense as a percentage of total revenue, was 47.0% for the quarter ended September 30, 2012 compared to 51.6% for the prior year period. Year-to-date through September 30, 2012 the Company's efficiency ratio was 55.8% compared to 55.2% for the same period in 2011.

The Company still expects noninterest expenses to be $20 to $22 million in the fourth quarter.

41

Income Taxes

For the quarter ended September 30, 2012, the Company’s income tax expense, which includes both federal and state taxes, was $4.2 million compared to $3.3 million for the same period in 2011. The combined federal and state effective income tax rates were 34.4% and 36.1% for the quarters ended September 30, 2012, and 2011, respectively.

For the nine months ended September 30, 2012, the Company’s income tax expense, which includes both federal and state taxes, was $11.7 million compared to a $9.6 million for the same period in 2011. The combined federal and state effective income tax rates were 33.9% and 34.6% for the nine months ended September 30, 2012 and 2011, respectively.

A valuation allowance is provided on deferred tax assets when it is more likely than not that some portion of the assets will not be realized. The Company did not have any valuation allowances for federal income taxes on its deferred tax asset of $18.0 million as of September 30, 2012 and $16.0 million as of December 31, 2011. Management believes it is more likely than not that the results of future operations will generate sufficient federal taxable income to realize the deferred federal tax assets. The Company had a state valuation allowance of $320,000 as of September 30, 2012, and as of December 31, 2011.

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 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's Board of Directors.Our liquidity position is monitored monthly by producing a liquidity report, which measures the amount of liquid versus non-liquid assets and liabilities. Ourliquidity management framework includes measurement of several key elements, such as the loan to deposit ratio, a liquidity ratio, and a dependency ratio. The Company's liquidity framework also incorporates contingency planning to assess the nature and volatility of funding sources and to determine alternatives to these sources. While core deposits and loan and investment repayments are principal sources of liquidity, funding diversification is another key element of liquidity management and is achieved by strategically varying depositor types, terms, funding markets, and instruments.

Parent Company liquidity

The parent company's liquidity is managed to provide the funds necessary to pay dividends to shareholders, service debt, invest in subsidiaries as necessary, and satisfy other operating requirements. The parent company's primary funding sources to meet its liquidity requirements are dividends and payments from the Bank and proceeds from the issuance of equity (i.e. stock option exercises, stock offerings). Another source of funding for the parent company includes the issuance of subordinated debentures. Excluding any redemption of preferred stock, management believes our current level of cash at the holding company of approximately $15.3 million will be sufficient to meet all projected cash needs for at least the next year.

42

As of September 30, 2012, 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

The Bank has a variety of funding sources available to increase financial flexibility. In addition to amounts currently borrowed, at September 30, 2012, the Bank could borrow an additional $114.3 million from the FHLB of Des Moines under blanket loan pledges and has an additional $637.8 million available from the Federal Reserve Bank under a pledged loan agreement. The Bank has unsecured federal funds lines with four correspondent banks totaling $45.0 million.

Of the $610.4 million of the securities available for sale at September 30, 2012, $271.8 million was pledged as collateral for deposits of public institutions, treasury, loan notes, and other requirements. The remaining $338.6 million could be pledged or sold to enhance liquidity, if necessary.

The Bank belongs to the Certificate of Deposit Account Registry Service, or CDARS, which allows us to provide our customers with access to additional levels of FDIC insurance coverage on their deposits. The Company considers the reciprocal deposits placed through the CDARS program as core funding and does not report the balances as brokered sources in its internal or external financial reports. As of September 30, 2012, the Bank had $36.1 million of reciprocal CDARS money market sweep balances and $5.5 million of reciprocal certificates of deposits outstanding. In addition to the reciprocal deposits available through CDARS, the Company has access to the “one-way buy” program, which allows the Company to bid on the excess deposits of other CDARS member banks. The Company will report any outstanding “one-way buy” funds as brokered funds in its internal and external financial reports. At September 30, 2012, we had no outstanding “one-way buy” deposits.

In addition, the Bank has the ability to sell certificates of deposit through various national or regional brokerage firms, if needed.

In the normal course of business, the Bank enters into certain forms of off-balance sheet transactions, including unfunded loan commitments and letters of credit. These transactions are managed through the Bank's various risk management processes. Management considers both on-balance sheet and off-balance sheet transactions in its evaluation of the Company's liquidity. The Bank has $767.9 million in unused commitments as of September 30, 2012. The nature of these commitments is such that the likelihood of funding them in the aggregate at any one time is low.

Capital Resources

The Company and the Bank are subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its bank affiliate must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The 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%). As of September 30, 2012, and December 31, 2011, 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 September 30, 2012, and December 31, 2011.

43

In June 2012, U.S. banking regulators released a notice of proposed rulemaking that would revise and replace the agencies' current regulatory capital requirements to align with the Basel III international capital standards and to implement certain changes required by the Dodd-Frank Act. While the proposal has not yet been adopted in final form, it is generally expected that it will require U.S. banks to hold higher amounts of capital, especially common equity, against their risk-weighted assets.

Among other things, the proposal changes the treatment of certain assets for purposes of calculating regulatory capital and revises the regulatory minimums, establishes a required “capital conservation buffer” and adopts a more conservative calculation of risk-weighted assets. The proposal provides for the following heightened capital requirements (on a fully phased-in basis):

• common equity Tier 1 capital to total risk-weighted assets of 7.0% (4.5% plus a capital conservation buffer of 2.5%);

• Tier 1 capital to total risk-weighted assets of 8.5% (6% plus a capital conservation buffer of 2.5%);

• total capital to total risk-weighted assets of 10.5% (8% plus a capital conservation buffer of 2.5%); and

• Tier 1 capital to adjusted average total assets (leverage ratio) of 4%.

If adopted in the proposed form, these new regulations would have several effects on the Company and its capital needs. For instance, $82.6 million of capital from the issuance of trust preferred securities would be phased-out as a component of Tier 1 capital over a ten-year period commencing January 1, 2013 (although these securities would continue to qualify as Tier 2 capital). The proposal provides different phase-in periods of various requirements over a number of years, with full phase-in of most aspects currently expected by 2019. Until the proposals are finalized and the timing of implementation of the new rules is determined, we cannot predict with certainty how we will be affected.

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

(Dollars in thousands)	September 30, 2012			December 31, 2011
Tier 1 capital to risk weighted assets	12.75		%	12.40		%
Total capital to risk weighted assets	14.12		%	13.78		%
Tier 1 common equity to risk weighted assets	7.91		%	7.32		%
Leverage ratio (Tier 1 capital to average tangible assets)	9.53		%	8.26		%
Tangible common equity to tangible assets	6.19		%	4.99		%
Tier 1 capital	$	300,104		$	276,275
Total risk-based capital	$	332,216		$	306,996

44

The Company believes the tangible common equity and Tier 1 common equity ratios are important financial measures of capital strength even though they are considered to be non-GAAP measures. The tables below contain reconciliations of these ratios to U.S. GAAP.

Tangible common equity ratio

Total risk weighted assets determined in accordance with prescribed regulatory requirements	2,353,251			2,227,958
Tier 1 common equity to risk weighted assets	7.91		%	7.32		%

While our regulatory capital ratios at the Bank are more than adequate, our capital plan targets a tangible common equity to tangible assets ratio of 7% or better by the end of 2014.  This capital plan contemplates 1) the redemption of all or part of the $35 million of preferred stock in the Company currently held by the U.S. Treasury through the Capital Purchase Program by the end of 2012 and 2) less focus on acquisition activities. The Company recently received regulatory approval to redeem all of the preferred stock and anticipates completing the redemption in the fourth quarter of 2012.

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 for the year ended December 31, 2011.

New Accounting Standards

FASB ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” On January 1, 2012, the Company adopted new authoritative guidance under this ASU which 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

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. The adoption of this guidance did not have a material impact on the the Company's consolidated financial statements.

FASB ASU 2011-05, “Presentation of Comprehensive Income" On January 1, 2012, the Company adopted new authoritative guidance 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. The adoption of this guidance did not have a material impact on the the Company's consolidated financial statements.

FASB ASU 2011-08, "Testing Goodwill for Impairment" On January 1, 2012, the Company adopted new authoritative guidance which permits entities to first perform a qualitative assessment to determine whether it is more likely than not (a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount. If the entity determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, it would perform the first step of the goodwill impairment test; otherwise, no further impairment test would be required. The adoption of this guidance did not have a material impact on the the Company's consolidated financial statements.

FASB ASU 2011-11, "Disclosures about Offsetting Assets and Liabilities" In December 2011, the FASB issued ASU 2011-11 which requires entities with financial instruments and derivatives that are either offset on the balance sheet or subject to a master netting or similar arrangement are required to disclose the following information separately for assets and liabilities in a tabular format:

• Gross amounts of recognized assets and liabilities

• Offsetting amounts that determine the net amount presented in the balance sheet

• Amounts subject to an enforceable master netting arrangement that were not already included in the disclosure required by (2) above, including

◦ Amounts related to recognized financial instruments and other derivative instruments if either (a) management makes an accounting election not to offset the amounts, or (b) the amounts do not meet

46

the right of setoff conditions in ASC 210-30-45, Balance Sheet: Offsetting, or in ASC 815-10-45, Derivatives and Hedging

◦ Amounts related to financial collateral

• Net amounts after deducting the amounts in (4) from the amounts in (3) above

In addition to the tabular disclosure described above, entities are required to provide a description of the setoff rights associated with assets and liabilities subject to an enforceable master netting arrangement. This ASU is effective for the years beginning on or after January 1, 2013, and interim periods within those annual periods. The guidance must be applied retrospectively for any period presented that begins before an entity's date of initial application. The Company believes this ASU will not have a material impact on the Company's consolidated financial statements.

FASB ASU 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05" On January 1, 2012, the Company adopted new authoritative guidance which indefinitely defers the new provisions under ASU 2011-05 which required entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented for both interim and annual financial statements. The adoption of this guidance did not have a material impact on the the Company's consolidated financial statements.

FASB ASU 2012-02, "Intangibles-Goodwill and Other (Topic 350)"In July 2012, the FASB issued ASU 2012-02 which allows an entity the option to first assess qualitative factors to determine if a quantitative impairment test of the indefinite-lived intangible asset is necessary. If the qualitative assessment reveals that it’s “more likely than not” that the asset is impaired, a calculation of the asset’s fair value is required. Otherwise, no quantitative calculation is necessary. This ASU is effective for annual and interim impairment tests performed for fiscal years beginning after Sept. 15, 2012. Early adoption is permitted. 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 September 30, 2012, demonstrate that a rising rate environment will have a positive impact on net interest income.

47

ITEM 4: CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the Company’s Chief Executive Officer (CEO) and the Chief Financial Officer (CFO), management has evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-15, as of September 30, 2012. Disclosure controls and procedures include without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2012 to provide reasonable assurance of the achievement of the objectives described above.

48

Changes to Internal Controls

There were no changes during the period covered by this Quarterly Report on Form 10-Q in the Company's internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, those controls.

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 for the fiscal year ended December 31, 2011, and as updated by the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2012:

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 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”). Upon the Bank's motion, the Court dismissed the plaintiffs' claim that the Bank violated its fiduciary duties. Plaintiffs, in the aggregate, are seeking damages from defendants, including the Bank, in excess of $44.0 million as well as their costs and attorneys’ fees and trebled damages under RICO.

The case was stayed while criminal proceedings against Sigillito were completed. After a four week trial, Sigillito was found guilty of 20 counts of wire fraud, mail fraud, conspiracy, and money laundering. Following the verdict, the judge lifted the stay and set the case for a four week jury trial starting August 26, 2013. Discovery is currently proceeding.

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. Like Rosemann, this case was stayed while the Sigillito criminal case was pending. The court has now granted the Bank's motion to compel arbitration and stay proceedings. Arbitration proceedings are not yet underway.

William Mark Scott v. Enterprise Financial Services Corp

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 made false and misleading statements and "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.

ITEM 1A: RISK FACTORS

For information regarding risk factors affecting the Company, 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, and Part I - Item 1A of our Report on Form 10-K for the fiscal year ended December 31, 2011, as amended in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2012, for information regarding risk factors.
