First Midwest Bancorp, Inc. ("First Midwest") (NASDAQ: FMBI) today reported net income for fourth quarter ended December 31, 2006 of $31.5 million, up 39.3% as compared to $22.6 million in fourth quarter 2005. First Midwest's net income for full year 2006 was $117.2 million, up 15.7% as compared to $101.4 million in 2005. Earnings per diluted share was $0.63 for fourth quarter ended December 31, 2006 and $2.37 for full year 2006, as compared to $0.49 for fourth quarter 2005 and $2.21 for full year 2005.

Performance for fourth quarter 2006 reflects certain counter balancing events:

--  Net realized securities gains of $3.4 million, or $0.04 per diluted
    share for fourth quarter 2006 as compared to net realized securities losses
    of $6.2 million, or $0.08 per diluted share, for fourth quarter 2005.
--  A $1.1 million increase in loan loss provisioning as compared to
    fourth quarter 2005, or $0.01 per diluted share, due in part to a $1.3
    million charge related to a single, purchased commercial lease.
--  The recognition of stock option expense of $650 thousand, or $0.01 per
    diluted share, in fourth quarter 2006 pursuant to the adoption of SFAS No.
    123R, "Share-Based Payment," on January 1, 2006.
--  The absence of employee severance costs in fourth quarter 2006 as
    compared to $679,000, or $0.01 per diluted share, in fourth quarter 2005.
    
Performance for full year 2006 reflects the following counter balancing events:
--  Net realized securities gains of $4.3 million, or $0.06 per diluted
    share in 2006 as compared to net realized securities losses of $3.3
    million, or $0.04 per diluted share, in 2005.
--  The negative impact of integration and related costs totaling $3.0
    million, or $0.04 per diluted share, recorded in the second quarter of 2006
    specific to the Bank Calumet acquisition.
--  Stock option expense of $2.8 million, or $0.04 per diluted share, in
    2006 recognized pursuant to the adoption of FAS 123R on January 1, 2006.
    
Fourth quarter 2006 performance resulted in an annualized return on average assets of 1.47%, as compared to 1.25% for fourth quarter 2005, and an annualized return on average equity of 16.4%, as compared to 16.6% for fourth quarter 2005.

"Our performance in 2006 reflects the cross-currents outlined above. All of this activity was accomplished in perhaps the most challenging interest rate environment on record," said First Midwest President and Chief Executive Officer John O'Meara.

"The successful acquisition and integration of Bank Calumet significantly increased our total assets and importantly expanded our suburban Chicago distribution network by over 40%. In addition to the benefits of Bank Calumet, our sales platform continues to perform at a high level, producing year over year growth in corporate lending, trust and asset management, and fee-based revenues. At the same time our planned reduction in the relative size of our securities portfolio is on track."

Earnings Guidance

O'Meara concluded, "The headwinds of the current interest rate and competitive environment continues to hamper earnings expansion in 2007 for both ourselves and the industry at large, primarily through margin compaction. In such an environment, the strength of our above-peer profitability, balance sheet, sales platform, and credit culture affords First Midwest opportunities to successfully weather this environment, while remaining focused on the long-term success of the Company. In 2007 solid corporate loan growth, low credit costs, increased fee-based revenues, diligent expense management, and the prudent administration of our securities portfolio are expected to continue to mitigate margin pressures. We currently expect full year diluted earnings per share to be in the range of $ 2.41 to $2.51."

Net Interest Margin

First Midwest's net interest income was $62.8 million for fourth quarter 2006, up 5.8% from $59.3 million for fourth quarter 2005. This increase was driven by a $1.0 billion increase in average interest-earning assets as compared to fourth quarter 2005, which was primarily due to the acquisition of Bank Calumet on March 31, 2006. Net interest margin for fourth quarter 2006 was 3.57%, down 12 basis points from third quarter 2006, reflecting the combined impact of the inverted interest rate yield curve on interest-earning asset yields and increased deposit and borrowing costs.

Securities Portfolio Activity

Total securities as of December 31, 2006 were $2.5 billion, down from $2.7 billion as of September 30, 2006, as proceeds received from mortgage-backed securities cash flows and the sale of municipal securities were not fully reinvested given the narrow spread between asset yields and funding costs available in the marketplace. In addition, fourth quarter 2006 market conditions afforded the opportunity to sell approximately $50 million of tax exempt municipal securities yielding, on a tax-equivalent basis, 7.43%, and realize a gain of $3.3 million. As of December 31, 2006, total municipal securities were $1.1 billion and reflected an unrealized $4.4 million in appreciation affording further balance sheet flexibility in 2007.

Increases in Loan Growth and Funding

Total loans grew to $5.0 billion as of December 31, 2006, an increase of 16.3% from December 31, 2005. This growth was due primarily to the addition of $676.4 million of loans acquired as part of the acquisition of Bank Calumet. Total loans as of December 31, 2006 declined $60.6 million, or 1.2%, as compared to September 30, 2006, reflecting lower consumer and corporate loan balances. Consumer loans declined $29.0 million on a linked quarter basis, primarily due to continued run off of the Company's indirect auto portfolio. Corporate loans declined $31.6 million, due to lower commercial and commercial real estate balances. While corporate sales activity was brisk throughout the quarter, large payoffs resulting from completed interim financing projects dampened outstandings.

Average deposits for fourth quarter 2006 totaled $6.2 billion, an increase of 20.0%, as compared to fourth quarter 2005, primarily as a result of deposits obtained through the acquisition of Bank Calumet. As compared to third quarter 2006, average deposits for fourth quarter 2006 declined $52.7 million, as growth in time deposit and savings account levels were offset by lower NOW and money market account balances, resulting primarily from seasonal declines in public fund deposits.

Noninterest Income and Expense

First Midwest's total noninterest income for fourth quarter 2006 was $29.7 million as compared to $14.4 million for fourth quarter 2005. Noninterest income for fourth quarter 2006 included $3.4 million in securities gains, and fourth quarter 2005 included $6.2 million in securities losses. The remaining components of noninterest income totaled $26.3 million for fourth quarter 2006, an increase of 27.8% as compared to fourth quarter 2005, reflecting higher fee-based revenues and revenue from corporate owned life insurance. In fourth quarter 2006, fee-based revenues totaled $23.3 million, an increase of $4.9 million or 26.4%, as compared to fourth quarter 2005, with approximately $3.4 million of this increase attributable to the acquisition of Bank Calumet, and the remainder reflecting higher service charges on deposit accounts and card-based revenues.

Total noninterest expense for fourth quarter 2006 was $47.8 million, up from $42.6 million in fourth quarter 2005. The majority of this increase is attributable to higher salaries, employee benefits, professional services, and occupancy expenses resulting from the acquisition of Bank Calumet.

First Midwest's efficiency ratio was 49.6% for fourth quarter 2006, as compared to 49.8% for fourth quarter 2005.

Stable Credit Quality

First Midwest's overall credit quality remained solid during fourth quarter 2006, with nonperforming assets as of December 31, 2006 totaling $18.9 million, down 12.1% as compared to $21.5 million at September 30, 2006. As of December 31, 2006, nonperforming assets, including foreclosed real estate, represented 0.38% of total loans plus foreclosed real estate, as compared to 0.35% as of December 31, 2005 and 0.42% as of September 30, 2006.

Net charge-offs for fourth quarter 2006 totaled $3.9 million and included a $1.3 million charge related to a single, purchased commercial lease. Net charge offs represented 0.30% of average loans for fourth quarter 2006, as compared to 0.25% for fourth quarter 2005 and 0.21% for third quarter 2006. Provisioning for loan losses for fourth quarter 2006 fully covered net charge-offs. As of December 31, 2006, the reserve for loan losses stood at 1.25% of total loans, as compared to 1.31% as of December 31, 2005 and 1.23% as of September 30, 2006 and represented 384.8% of nonperforming loans.

Solid Capital Management

As of December 31, 2006, First Midwest's Total Risk Based Capital ratio was 12.2%, compared to 11.8% as of December 31, 2005. The Tier 1 Risk Based Capital ratio was 9.6% as compared to 10.7% as of December 31, 2005. First Midwest's Tier 1 Leverage Ratio was 7.3% as compared to 8.2% as of December 31, 2005.

First Midwest's tangible capital ratio, which represents the ratio of stockholders' equity to total assets excluding intangible assets, stood at 5.62%, down from 6.30% as of December 31, 2005. The acquisition of Bank Calumet on March 31, 2006 reduced the tangible capital ratio by 55 basis points as a result of the net impact of the additional goodwill and other intangible assets acquired and common shares issued. In addition, a negative $8.6 million adjustment to equity decreased the tangible capital ratio by 10 basis points. This adjustment resulted from the adoption of SFAS No. 158, "Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans," effective December 31, 2006.

In 2006, First Midwest elected to suspend its stock repurchase program, as it rebuilds tangible capital following the acquisition of Bank Calumet. With 2.1 million shares remaining under its existing authorization, First Midwest may reinstate its repurchase program in 2007, with the pace and timing of repurchase activity, if any, dependent upon market conditions and other factors.
