SUMMARY UPDATE

“The quarter reflected continued, solid improvement in our underlying business, offset, in part, by higher provision for loan losses,” said Michael L. Scudder, President and Chief Executive Officer of First Midwest Bancorp, Inc. “Operating earnings improved significantly from last quarter, benefitting from broad-based sales momentum as well as controlled spending. Prior investments in our business platforms, combined with realignment of our resources, helped drive meaningful growth in both lending and fee-based revenues in addition to lower operating costs.”

Mr. Scudder continued, “Increases in both charge-offs and the provision for loan losses are indicative of our ongoing evaluation of our existing and potential problem loans and our remediation strategies consistent with our previously stated intention to make greater progress in reducing problem credits. Given the challenges these credits pose, we continue to evaluate all of our remediation strategies with a sharpened focus on the accelerated reduction of both existing and potential problem credits, thereby minimizing future credit costs over the longer term.”

Mr. Scudder concluded, “The strength of our capital and operating earnings leaves us well positioned to meet the needs of our clients as we pursue opportunities for growth, react to evolving regulatory expectations, and transition to improved credit performance.”

(1)

The Company’s accounting and reporting policies conform to U.S. generally accepted accounting principles (“GAAP”) and general practice within the banking industry. As a supplement to GAAP, the Company provided this non-GAAP performance result, which the Company believes is useful because it assists investors in assessing the Company’s operating performance. Although it is intended to enhance investors’ understanding of the Company’s business and performance, this non-GAAP financial measure should not be considered an alternative to GAAP.

(2)

This item represents costs related to an organizational realignment that included the elimination of 38 positions in first quarter 2012.

Pre-tax, pre-provision operating earnings for second quarter 2012 increased $3.4 million from first quarter 2012 and decreased $2.1 million from second quarter 2011. The increase from first quarter 2012 resulted from an increase in net interest income and fee-based revenues and lower noninterest expense, excluding losses on sales and write-downs of OREO, primarily from lower salaries and employee benefits.

The decline in pre-tax, pre-provision operating earnings from second quarter 2011 is primarily attributed to a reduction in net interest income, reflecting the continued decline in covered interest-earning assets, lower yields earned on loans and investments, and the cost of additional senior debt, partially mitigated by the decline in rates paid on other interest-bearing liabilities.

Further discussion of net interest income and noninterest income and expense is presented in later sections of this release.

(1)

Revenue from tax-exempt securities and investments that receive tax credits is presented on a basis comparable to taxable securities and investments. Consequently, interest income and yields are presented on a tax-equivalent basis, assuming a federal income tax rate of 35%. This non-GAAP financial measure assists management in assessing the comparability of revenue arising from both taxable and tax-exempt sources. The corresponding income tax impact related to tax-exempt items is recorded within income tax expense. These adjustments have no impact on net income.

(2)

Covered interest-earning assets consist of loans acquired through the Company’s Federal Deposit Insurance Corporation (“FDIC”)-assisted transactions and the related FDIC indemnification asset.

Average interest-earning assets for second quarter 2012 increased $156.6 million, or 2.2%, from first quarter 2012 and declined $76.2 million, or 1.0%, compared to second quarter 2011. Loan growth across several categories, particularly commercial and industrial (“C&I”), resulted in higher average loans, excluding covered loans, and drove the rise in interest-earning assets from first quarter 2012. The decrease from second quarter 2011 was due primarily to the continuing decline in covered interest-earning assets.

Average funding sources for second quarter 2012 were $159.2 million higher than first quarter 2012 and up $99.9 million from second quarter 2011. For second quarter 2012 compared to both prior periods, growth in demand deposits offset the decline in interest-bearing liabilities, which resulted in a more favorable product mix. In addition, the increase from first quarter 2012 also reflected seasonal growth in public fund balances.

The growth in average senior and subordinated debt for second quarter 2012 compared to second quarter 2011 is attributed to the issuance of $115.0 million in senior debt during the fourth quarter of 2011. Interest paid on the senior debt reduced net interest margin by 10 basis points for first and second quarter 2012.

4

Tax-equivalent net interest margin for second quarter 2012 was stable at 3.88% compared to first quarter 2012 and 22 basis points lower than second quarter 2011. The decrease from second quarter 2011 primarily reflects the impact of lower yields earned on investment securities and loans, resulting from a decline in market interest rates, and the cost of additional senior debt, partially offset by lower rates paid for other interest-bearing deposits.

Interest earned on covered loans is generally recognized through the accretion of the discount taken on expected future cash flows. The increase in the yield on covered interest-earning assets from first quarter 2012 was driven by adjustments for revised estimates of future cash flows. The yield decreased from second quarter 2011 due to adjustments in the prior period related to actual cash realized in excess of estimates upon final settlement of certain covered loans that were not experienced in the current quarter.

N/M — Not meaningful.

(1) Net trading (losses) gains result from changes in the fair value of diversified investment securities held in a grantor trust under deferred compensation agreements and are substantially offset by nonqualified plan expense for each period presented.

Fee-based revenues for second quarter 2012 grew 4.7% compared to first quarter 2012 and declined 2.3% compared to second quarter 2011. The increase in fee-based revenues from first quarter 2012 to second quarter 2012 was due to higher service charges on business accounts (included in service charges on deposit accounts) resulting from price increases and successful cross-selling initiatives. In addition, increased transaction volumes contributed to a rise in merchant fees (included in other service charges, commissions, and fees) and card-based fees.

The variance in fee-based revenues from second quarter 2011 to second quarter 2012 resulted from lower non-sufficient funds (“NSF”) fees (included in service charges on deposit accounts) and was mitigated by increases in service charges on business accounts as discussed above and higher card-based fees from growth in the number of outstanding cards.

N/M — Not meaningful.

(1) Nonqualified plan expense results from changes in the Company’s obligation to participants under deferred compensation agreements.

Total noninterest expense for second quarter 2012 declined 2.3% compared to first quarter 2012 and 6.9% compared to second quarter 2011.

Second quarter 2012 salaries and wages decreased by $1.3 million from first quarter 2012 and $1.0 million from second quarter 2011 due to the organizational realignment in fourth quarter 2011, resulting in the reduction of approximately 100 positions, and higher levels of deferred salaries from new loan growth, partially offset by annual merit increases. The decline in retirement and other employee benefits compared to first quarter 2012 and second quarter 2011 was impacted by the timing of certain benefit accruals.

The increase in OREO expenses from first quarter 2012 resulted from greater asset sales and write-downs related to the reappraisal of property values and alignment of underlying collateral values with remediation strategies.

Loan remediation costs were elevated in second quarter 2012 compared to both prior periods presented due to an increase in legal fees incurred to remediate problem credits and higher real estate taxes paid by the Company to preserve its rights to collateral associated with problems loans.

Compared to first quarter 2012, net occupancy expense decreased in the current period as a result of normal seasonal declines in certain maintenance and utilities costs. In addition, a decrease in real estate taxes contributed to lower net occupancy expense in second quarter 2012 compared to both prior periods presented.

(1) Approximately $50 million of loans as of June 30, 2011 were reclassified into other categories as of June 30, 2012, primarily office and retail commercial real estate.

Total loans, excluding covered loans, of $5.3 billion grew by $160.7 million from March 31, 2012 and $185.1 million from June 30, 2011, reflecting the impact of broader product offerings and expanded sales distribution within our markets. The Company experienced growth of 6.7% in C&I loans and 14.7% in agricultural lending from March 31, 2012. Continued efforts to reduce lending exposure to less favorable real estate categories contributed to the decline in the residential construction portfolio.

In addition to C&I loans and agricultural lending, the increase from June 30, 2011 to June 30, 2012 also benefitted from growth in the office, retail and industrial portfolio, and 1-4 family mortgages.

(1) Covered loans and covered OREO were acquired through transactions with the FDIC and are subject to loss sharing agreements with the FDIC whereby the Company is indemnified against the majority of any losses incurred on these assets.

Non-performing assets, excluding covered loans and covered OREO, were $242.8 million at June 30, 2012, a reduction of $1.8 million from March 31, 2012. While non-accrual loans remained relatively consistent with the prior quarter, the mix of non-performing assets improved as TDRs increased $5.7 million.

During the quarter, management restructured $7.0 million of loans at market rates and terms incurring a loss of approximately $800,000. Management expects to reclassify these loans from restructured to performing in the first quarter of 2013, assuming continued performance. Also, during second quarter 2012, the Company sold $13.4 million of OREO with proceeds of approximately 94% of carrying value and recorded additional write-downs of $1.7 million related to updated appraisals and changes in strategies intended to accelerate disposition.

The Company increased the provision for loan losses from first quarter 2012 by $4.2 million, which maintained the allowance for credit losses at $118.7 million and supports management’s ongoing assessment of credit quality.

Approximately one-third of the charge-offs, excluding covered charge-offs, for the quarter was comprised of three construction credits and reflects the alignment of underlying collateral values with current appraisals and planned remediation strategies.

Management periodically revises its estimates of future cash flows from covered loans. Increases in cash flows are recognized prospectively in interest income. The present value of any decreases in expected cash flows, net of reimbursement from the FDIC, is recorded in the current period through a charge-off in the allowance for loan losses.

CAPITAL MANAGEMENT

Capital Ratios

(Dollar amounts in thousands)

	June 30, 2012		December 31, 2011		Regulatory Minimum For “Well- Capitalized”		Excess Over Required Minimums at June 30, 2012
Regulatory capital ratios:
Total capital to risk-weighted assets	13.26	%	13.68	%	10.00	%	33	%	$	208,744
Tier 1 capital to risk-weighted assets	11.21	%	11.61	%	6.00	%	87	%	$	333,978
Tier 1 leverage to average assets	9.24	%	9.28	%	5.00	%	85	%	$	329,882
Tier 1 common capital to risk-weighted assets (1)	10.21	%	10.26	%	N/A	(2)	N/A	(2)	N/A		(2)
Tangible common equity ratios (3):
Tangible common equity to tangible assets	8.91	%	8.83	%	N/A	(2)	N/A	(2)	N/A		(2)
Tangible common equity, excluding other comprehensive loss, to tangible assets	9.06	%	9.00	%	N/A	(2)	N/A	(2)	N/A		(2)
Tangible common equity to risk-weighted assets	10.87	%	10.88	%	N/A	(2)	N/A	(2)	N/A		(2)

(1)	Excludes the impact of trust-preferred securities.
(2)	Ratio is not subject to formal Federal Reserve regulatory guidance.
(3)	Tangible common equity (“TCE”) represents common stockholders’ equity (i.e., total stockholders’ equity less preferred stock) less goodwill and identifiable intangible assets, net of related deferred tax liabilities. Return on TCE measures the Company’s earnings as a percentage of TCE. In management’s view, Tier 1 common and TCE measures are meaningful to the Company, as well as analysts and investors, in assessing the Company’s use of equity and in facilitating comparisons with competitors.

The Company’s regulatory ratios as of June 30, 2012 exceeded all regulatory mandated ratios for characterization as “well-capitalized.”

In first quarter 2012, the Company repurchased and retired approximately $21 million out of a total of $84.7 million in 6.95% trust preferred junior subordinated debentures (“TRUPs”) at a discount of 2.25%. This transaction resulted in the recognition of a pre-tax gain of $256,000. Although the TRUPs were included as a component of Tier 1 capital, the Company elected to retire them given the low interest rate environment.

The Board of Directors reviews the Company’s capital plan each quarter, giving consideration to the current and expected operating environment as well as an evaluation of various capital alternatives.
