WINTRUST FINANCIAL CORPORATION REPORTS
THIRD QUARTER 2008 RESULTS

LAKE FOREST, ILLINOIS — Wintrust Financial Corporation (“Wintrust” or “the Company”) (Nasdaq: WTFC) announced a quarterly net loss of $2.4 million, or $0.12 per diluted share, for the period ended September 30, 2008, a decrease of $0.52 per diluted share, compared to the $9.9 million of net income, or $0.40 per diluted share, recorded in the third quarter of 2007. Compared to the second quarter of 2008, earnings per diluted share decreased $0.59 per diluted share, on a $13.7 million decrease in net income.

Edward J. Wehmer, President and Chief Executive Officer, commented, “While the results of the third quarter are disappointing, the Company has made net profits of $18.5 million during 2008. The net loss during the third quarter was a direct result of a $24.1 million provision for credit losses. As a result of the increased provision for credit losses, the Company’s loan loss reserve level stands at a historically high level.”

Mr. Wehmer noted, “The banking industry is experiencing unprecedented economic times and real estate valuations have become extraordinarily distressed due to lack of sales activity and other factors. These distressed real estate valuations caused the Company to have increased credit costs that are higher than anticipated and more than we have historically recorded. We are focused on resolving existing problem credits which we believe are still manageable and controllable.”

Mr. Wehmer went on to say, “We strengthened our balance sheet in the third quarter by raising $50 million in capital and by the increased loan loss reserve level. The Company and all 15 of its affiliate banks remain above well-capitalized levels for regulatory purposes. The additional capital enhanced our ability to weather the current economic storm as well as our ability to fund future growth.”

Mr. Wehmer added, “The Company continued to grow both its loan and deposit balances during the quarter, increasing $169 million and $68 million, respectively. We believe the opportunities for continued growth

are present but we are currently taking a tempered approach to that growth. Our successful community banking model is proving to be a competitive advantage in these tough economic times as our banks are predominantly funded by a stable base of retail deposits rather than by volatile wholesale funding vehicles.”

Mr. Wehmer summarized, “Focusing on our core local markets over the past three and half years has limited our exposure to much of the global harm that has been in the news. However, the distressed housing market and related real estate values have presented us with challenges. Our goal is to resolve the problem loan issues as soon as possible so we can resume our proven growth strategy and return earnings to acceptable levels.”

Net income for the nine months ended September 30, 2008 was $18.5 million, or $0.75 per diluted common share compared to $40.0 million, or $1.59 per diluted common share, in the first nine months of 2007. Total assets of $9.9 billion at September 30, 2008 increased $400 million from September 30, 2007. Total deposits as of September 30, 2008 were $7.8 billion, an increase of $251 million as compared to $7.6 billion at September 30, 2007.

Total loans grew to $7.3 billion as of September 30, 2008, an increase of $514 million, or 8%, over the $6.8 billion balance as of September 30, 2007. The Company’s loan portfolio includes a wide variety of loan types, of which approximately 9% are commercial real estate construction and land development related and 6% are residential real estate construction and land development related. These projects are being carefully monitored on an individual credit basis at each bank.

Total shareholders’ equity increased to $809 million, or a book value of $32.07 per common share, at September 30, 2008, compared to $722 million, or a book value of $30.55 per common share, at September 30, 2007.

⁽¹⁾		Net revenue is net interest income plus non-interest income.

⁽²⁾		Core net interest margin excludes interest expense associated with Wintrust’s junior subordinated debentures and the interest expense incurred to fund common stock repurchases.

⁽³⁾		The net overhead ratio is calculated by netting total non-interest expense and total non-interest income, annualizing this amount, and dividing by that period’s total average assets. A lower ratio indicates a higher degree of efficiency.

⁽⁴⁾		See “Supplemental Financial Measures/Ratios” for additional information on this performance measure/ratio.

⁽⁵⁾		Period-end balance sheet percentage changes are annualized.

Certain returns, yields, performance ratios, or quarterly growth rates are “annualized” in this presentation to represent an annual time period. This is done for analytical purposes to better discern for decision-making purposes underlying performance trends when compared to full-year or year-over-year amounts. For example, balance sheet growth rates are most often expressed in terms of an annual rate like 20%. As such, a 5% growth rate for a quarter would represent an annualized 20% growth rate.

Acquisitions, Stock Offering/Regulatory Capital and New Locations – Impacting
Comparative Financial Results

Acquisitions

On November 1, 2007, the Company completed its previously announced acquisition of 100% of the ownership interests of Broadway Premium Funding Corporation (“Broadway”). Broadway was founded in 1999 and had approximately $60 million of premium finance receivables outstanding at the date of acquisition. Broadway provides financing for commercial property and casualty insurance premiums, mainly through insurance agents and brokers in the northeastern portion of the United States and California. The results of operations of Broadway are included in Wintrust’s consolidated financial results only since the effective date of acquisition.

Stock Offering/Regulatory Capital

The Company did not repurchase any of its outstanding common stock during the first nine months of 2008.

The Company announced on August 26, 2008 that it sold $50 million ($49.4 million net of issuance costs) of non-cumulative perpetual convertible preferred stock in a private transaction. If declared, dividends on the preferred stock are payable quarterly in arrears at a rate of 8.00% per annum. The shares are convertible into common stock at the option of the holder at a price per share of $27.38 which is equal to 120% of the average of the midpoint of the intraday high and intraday low trading prices for the Company’s common stock for the fifteen consecutive trading day period ended August 22, 2008. On and after August 26, 2010, the preferred stock will be subject to mandatory conversion into common stock under certain circumstances.

The entire issue was purchased by funds controlled by CIVC Partners, a Chicago based private equity firm focused on providing capital to high growth companies in financial services, business services, and media and information services. CIVC is very familiar with Wintrust as CIVC successfully invested in the Company in the past.

De Novo/Acquired Banking Locations Activity

Over the past 12 months, Wintrust opened the following banking locations:

	–		Vernon Hills, Illinois (Libertyville Bank & Trust Company) – opened second quarter 2008

	–		Deerfield, Illinois (Northbrook Bank & Trust Company) – opened first quarter 2008

Financial Performance Overview

For the third quarter of 2008, net interest income totaled $60.7 million, down $5.5 million compared to the third quarter of 2007. Average earning assets for the third quarter of 2008 increased by $455 million compared to the third quarter of 2007. Average loans increased by $464 million, accounting for essentially all of the earning asset growth over the past 12 months. The average earning asset growth of $455 million over the past 12 months was funded by a $382 million increase in the average balances of Savings, NOW, MMA and Wealth Management deposits, an increase in the average balance of net free funds of $116 million, an increase in the average balance of wholesale borrowings (primarily repurchase agreements) of $104 million, decreases in the average balance of retail certificates of deposit of $100 million and the average balance of brokered certificates of deposit of $47 million. At September 30, 2008, $191 million of retail deposits are held in the Company’s MaxSafe^® suite of products (certificates of deposit, MMA and NOW). MaxSafe is an innovative investment alternative that provides up to 15 times (currently $3.75 million for interest-bearing accounts) the FDIC insurance security of a traditional banking deposit by depositing a customer’s funds across all 15 of the Company’s community banks.

The net interest margin for the third quarter of 2008 was 2.74%, compared to 3.14% in the third quarter of 2007 and 2.77% in the second quarter of 2008. Core net interest margin, which excludes both the impact of the Company’s junior subordinated debentures and the common stock repurchases on the net interest margin, was 2.97% in the third quarter of 2008, down compared to 3.43% in the third quarter of 2007 and a decrease from the 3.02% in the second quarter of 2008. The decrease in the net interest margin in the third quarter of 2008 when compared to the third quarter of 2007 is directly attributable to interest rate compression as certain variable rate retail deposit rates are unable to decline at the same magnitude as variable rate earning assets and the negative impact of an increased balance of nonaccrual loans. For the year, compression in the net interest margin was effectively offset, as has consistently been the case, by the Company’s covered call strategy. An illustration of the past effectiveness of this strategy is shown in the Supplemental Financial Information section (see page titled “Net Interest Margin (Including Call Option Income).”)

In the third quarter of 2008, the yield on loans decreased 188 basis points and the rate on interest-bearing deposits decreased 130 basis points compared to the third quarter of 2007. Management believes opportunities for increasing spreads in the commercial and commercial real estate portfolio should help offset the effects of

interest rate spread compression on variable rate retail deposits and the unprecedented competitive retail deposit pricing given the current economic conditions that have hindered net interest margin expansion.

Non-interest income totaled $21.9 million in the third quarter of 2008, increasing $10.4 million, or 90%, compared to the third quarter of 2007. The increase was primarily attributable to mortgage banking revenue increasing $7.6 million and an additional $2.7 million from fees on covered call option contracts written against certain U.S. Treasury and agency securities held in the Company’s portfolio for liquidity and other purposes. Mortgage banking revenue in the third quarter of 2007 included charges for $6.7 million (pre-tax) to reflect estimated losses relating to recourse obligations on residential mortgage loans sold to investors and losses on certain residential loans held for sale. Net available-for-sale securities gains also increased $996,000 in the third quarter of 2008 compared to the third quarter of 2007. The third quarter of 2008 security gains were offset by $2.1 million (pre-tax) of other-than-temporary impairment charges primarily associated with corporate debt investments. Revenue from bank owned life insurance decreased $1.7 million primarily as a result of a $1.4 million death benefit recorded in the third quarter of 2007.

Non-interest expense totaled $63.0 million in the third quarter of 2008, increasing $3.5 million, or 6%, compared to the third quarter of 2007. Salary and employee benefits expense increased $1.6 million, or 5%, while equipment costs increased $140,000, data processing costs increased $205,000, occupancy costs increased $363,000, professional fees increased $438,000, the increase in FDIC insurance premiums added $277,000 of additional expense and other miscellaneous expenses increased $673,000 (the primary contributor being expenses related to other real estate owned).

Non-performing loans totaled $113.0 million, or 1.54% of total loans, at September 30, 2008, compared to $86.8 million, or 1.21% of total loans, at June 30, 2008 and $46.9 million, or 0.69% of total loans, at September 30, 2007. Total non-performing loans increased by $26.2 million since June 30, 2008. Other real estate acquired in foreclosure of $12.5 million at September 30, 2008 increased $3.3 million compared to June 30, 2008.

million of residential real estate and home equity related loans and $269,000 of consumer related loans. Twelve of these relationships exceed $2.5 million in outstanding balances, approximating $69.1 million in total outstanding balances.

The provision for credit losses totaled $24.1 million for the third quarter of 2008 compared to $10.3 million for the second quarter of 2008 and $4.4 million in the third quarter of 2007. Net charge-offs for the third quarter totaled 84 basis points on an annualized basis compared to 17 basis points on an annualized basis in the third quarter of 2007 and 36 basis points on an annualized basis in the second quarter of 2008. The provision for credit losses in the third quarter and the first nine months of 2008 reflects the Company’s current net charge-offs and credit quality levels. Annualized net-charge-offs as a percentage of average loans for the first nine months of 2008 were 50 basis points, compared to 12 basis points on an annualized basis in the first nine months of 2007. The provision for credit losses totaled $43.0 million in the first nine months of 2008 compared to $8.7 million in the first nine months of 2007.

SUPPLEMENTAL FINANCIAL MEASURES/RATIOS

The accounting and reporting policies of Wintrust conform to generally accepted accounting principles (“GAAP”) in the United States and prevailing practices in the banking industry. However, certain non-GAAP performance measures and ratios are used by management to evaluate and measure the Company’s performance. These include taxable-equivalent net interest income (including its individual components), net interest margin (including its individual components), core net interest margin and the efficiency ratio. Management believes that these measures and ratios provide users of the Company’s financial information a more meaningful view of the performance of the interest-earning and interest-bearing liabilities and of the Company’s operating efficiency. Other financial holding companies may define or calculate these measures and ratios differently.

Management reviews yields on certain asset categories and the net interest margin of the Company and its banking subsidiaries on a fully taxable-equivalent (“FTE”) basis. In this non-GAAP presentation, net interest income is adjusted to reflect tax-exempt interest income on an equivalent before-tax basis. This measure ensures comparability of net interest income arising from both taxable and tax-exempt sources. Net interest income on a FTE basis is also used in the calculation of the Company’s efficiency ratio. The efficiency ratio, which is calculated by dividing non-interest expense by total taxable-equivalent net revenue (less securities gains or losses), measures how much it costs to produce one dollar of revenue. Securities gains or losses are excluded from this calculation to better match revenue from daily operations to operational expenses.

Management also evaluates the net interest margin excluding the net interest expense associated with the Company’s junior subordinated debentures and the interest expense incurred to fund common stock repurchases (“Core Net Interest Margin”). Because junior subordinated debentures are utilized by the Company primarily as capital instruments and the cost incurred to fund common stock repurchases is capital utilization related, management finds it useful to view the net interest margin excluding these expenses and deems it to be a more meaningful view of the operational net interest margin of the Company.

A reconciliation of certain non-GAAP performance measures and ratios used by the Company to evaluate and measure the Company’s performance to the most directly comparable GAAP financial measures is shown below:

(8)		See “Supplemental Financial Measures/Ratios” for additional information on this performance measure/ratio.

Net interest income, which is the difference between interest income and fees on earning assets and interest expense on deposits and borrowings, is the major source of earnings for Wintrust. Tax-equivalent net interest income for the quarter ended September 30, 2008 totaled $61.3 million, a decrease of $5.7 million, or 8%, as compared to the $66.9 million recorded in the same quarter of 2007.

junior subordinated debentures and the interest expense related to the common stock repurchases, was 2.97% for the third quarter of 2008 and 3.43% for the third quarter of 2007.

The yield on total earning assets for the third quarter of 2008 was 5.68% as compared to 7.29% in the third quarter of 2007. The third quarter 2008 yield on loans was 5.89%, a 188 basis point decrease when compared to the prior year third quarter yield of 7.77%. The liquidity management assets yield in the third quarter of 2008 was 4.70% compared to 5.13% in the third quarter of 2007.

The rate paid on interest-bearing liabilities decreased to 3.16% in the third quarter of 2008 as compared to 4.41% in the third quarter of 2007. The cost of interest-bearing deposits decreased in the third quarter of 2008 to 2.98% compared to 4.28% in the third quarter of 2007. The rate paid on wholesale funding, consisting of Federal Home Loan Bank of Chicago advances, notes payable, subordinated notes, other borrowings and junior subordinated debentures, decreased to 4.24% in the third quarter of 2008 compared to 5.27% in the third quarter of 2007. The Company utilizes certain borrowing sources to fund the additional capital requirements of the subsidiary banks, manage its capital, manage its interest rate risk position and for general corporate purposes.

The lower levels of net interest income and net interest margin in the third quarter of 2008 were caused by margin compression. The Company has made progress in shifting its mix of retail deposits away from certificates of deposit into lower cost, more variable rate NOW, savings, money market and wealth management deposits. Interest rate compression on large portions of NOW, savings and money market accounts as the Federal Reserve quickly lowered rates prevented these deposits from repricing at the same magnitude as variable rate earning assets. Management believes opportunities for increasing spreads in the commercial and commercial real estate portfolio should help offset the effects of interest rate spread compression on variable rate retail deposits and the unprecedented competitive retail deposit pricing given the current economic conditions that have hindered net interest margin expansion. The average loan-to-average deposit ratio increased to 94.1% in the third quarter of 2008 from 91.3% in the third quarter of 2007. In the fourth quarter of 2007 the Company reinstated its program of selling premium finance receivables as the average loan-to-average deposit ratio was above the target of 85% to 90%. The higher nature of this ratio is primarily a result of the strong commercial and commercial real estate loan growth combined with a restricted market for loan sales and securitizations.

Net interest income, which is the difference between interest income and fees on earning assets and interest expense on deposits and borrowings, is the major source of earnings for Wintrust. Tax-equivalent net interest income for the quarter ended September 30, 2008 totaled $61.3 million, an increase of $1.3 million, or 2%, as compared to the $60.0 million recorded in the second quarter of 2008.

Net interest margin represents tax-equivalent net interest income as a percentage of the average earning assets during the period. For the third quarter of 2008, the net interest margin was 2.74%, down three basis points when compared to the second quarter of 2008. The core net interest margin, which excludes the net interest expense related to Wintrust’s junior subordinated debentures and the interest expense related to the common stock repurchases, was 2.97% for the third quarter of 2008 and 3.02% for the second quarter of 2008.

The yield on total earning assets for the third quarter of 2008 was 5.68% as compared to 5.84% in the second quarter of 2008. The third quarter 2008 yield on loans was 5.89%, a 23 basis point decrease when compared to the second quarter 2008 yield of 6.12%. The decline in loan yield was primarily attributable to interest reversed on loans placed in nonaccrual status during the third quarter of 2008. The liquidity management assets yield in the third quarter of 2008 was 4.70% compared to 4.56% in the second quarter of 2008.

The rate paid on interest-bearing liabilities decreased to 3.16% in the third quarter of 2008 as compared to 3.31% in the second quarter of 2008. The cost of interest-bearing deposits decreased in the third quarter of 2008 to 2.98% compared to 3.14% in the second quarter of 2008. The rate paid on wholesale funding, consisting of Federal Home Loan Bank of Chicago advances, notes payable, subordinated notes, other borrowings and junior subordinated debentures, decreased to 4.24% in the third quarter of 2008 compared to 4.29% in the second quarter of 2008. The Company utilizes certain borrowing sources to fund the additional capital requirements of the subsidiary banks, manage its capital, manage its interest rate risk position and for general corporate purposes.

The higher level of net interest income recorded in the third quarter of 2008 compared to the second quarter of 2008 was offset by continued margin compression. Higher levels of interest reversed on loans placed in nonaccrual status, higher average balances of nonaccrual loans and lower contributions from net free funds as a result of lower interest rates caused the margin to decline by three basis points. Average earning asset growth of $185 million in the third quarter of 2008 compared to the second quarter of 2008 was generated entirely in the loan portfolio. This growth was funded by a $64 million increase in the average balances of Savings, NOW, MMA and Wealth Management deposits, an increase in the average balance of retail certificates of deposit of $196 million, an increase in the average balance of net free funds of $4 million, decreases in the average balance of wholesale borrowings (primarily notes payable at the holding company) of $39 million and the average balance of brokered certificates of deposit of $40 million. At September 30, 2008, $191 million of retail deposits are held in the Company’s MaxSafe suite of products (certificates of deposit, MMA and NOW). MaxSafe is an innovative and unmatched investment alternative that provides up to 15 times (currently $3.75 million for interest-bearing deposits) the FDIC insurance security of a traditional banking deposit by depositing a customer’s funds across all 15 of the Company’s community banks.

The average loan-to-average deposit ratio was 94.1% in the third quarter of 2008 compared to 94.6% in the second quarter of 2008. The higher nature of this ratio is primarily a result of the strong commercial and commercial real estate loan growth combined with a restricted market for loan sales and securitizations.

The following table presents a summary of Wintrust’s average balances, net interest income and related net interest margins, calculated on a fully tax-equivalent basis, for the nine months ended September 30, 2008 compared to the nine months ended September 30, 2007:

(1)		Liquidity management assets include available-for-sale securities, interest earning deposits with banks, federal funds sold and securities purchased under resale agreements.

(2)		Interest income on tax-advantaged loans, trading account securities and securities reflects a tax-equivalent adjustment based on a marginal federal corporate tax rate of 35%. The total adjustments for the nine months ended September 30, 2008 and 2007 were $1.9 million and $2.3 million, respectively.

(3)		Other earning assets include brokerage customer receivables and trading account securities.

(4)		Loans, net of unearned income, include mortgages held-for-sale and non-accrual loans.

(5)		Interest rate spread is the difference between the yield earned on earning assets and the rate paid on interest-bearing liabilities.

(6)		Net free funds are the difference between total average earning assets and total average interest-bearing liabilities. The estimated contribution to net interest margin from net free funds is calculated using the rate paid for total interest-bearing liabilities.

(7)		The core net interest margin excludes the effect of the net interest expense associated with Wintrust’s junior subordinated debentures and the interest expense incurred to fund common stock repurchases.

(8)		See “Supplemental Financial Measures/Ratios” for additional information on this performance measure/ratio.

Net interest income, which is the difference between interest income and fees on earning assets and interest expense on deposits and borrowings, is the major source of earnings for Wintrust. Tax-equivalent net interest income for the nine months ended September 30, 2008 totaled $183.7 million, a decrease of $14.7 million, or 7%, as compared to the $198.4 million recorded in the first nine months of 2007.

Net interest margin represents tax-equivalent net interest income as a percentage of the average earning assets during the period. For the first nine months of 2008, the net interest margin was 2.83%, down 30 basis points when compared to the first nine months of 2007. The core net interest margin, which excludes the net interest expense related to Wintrust’s junior subordinated debentures and the interest expense related to the common stock repurchases, was 3.08% for the first nine months of 2008 and 3.39% for the first nine months of 2007.

The yield on total earning assets for the first nine months of 2008 was 6.01% as compared to 7.27% in the first nine months of 2007. The first nine months of 2008 yield on loans was 6.27%, a 154 basis point decrease when compared

to the prior year first nine months yield of 7.81%. The liquidity management assets yield in the first nine months of 2008 was 4.75% compared to 5.16% in the first nine months of 2007.

The rate paid on interest-bearing liabilities decreased to 3.42% in the first nine months of 2008 as compared to 4.43% in the first nine months of 2007. The cost of interest-bearing deposits decreased in the first nine months of 2008 to 3.25% compared to 4.30% in the first nine months of 2007. The rate paid on wholesale funding, consisting of Federal Home Loan Bank of Chicago advances, notes payable, subordinated notes, other borrowings and junior subordinated debentures, decreased to 4.43% in the first nine months of 2008 compared to 5.28% in the first nine months of 2007. The Company utilizes certain borrowing sources to fund the additional capital requirements of the subsidiary banks, manage its capital, manage its interest rate risk position and for general corporate purposes.

The lower levels of net interest income and net interest margin in the first nine months of 2008 were caused by margin compression. During the first nine months of 2008, the cost of interest-bearing deposits declined 105 basis points while the yield on total loans decreased 154 basis points. This interest-rate spread compression combined with a five basis point reduction in the contribution from net free funds contributed to the 30 basis point decline in net interest margin. Year-to-date average loan growth of $416 million in 2008 compared to 2007 was funded by a $346 million increase in the year-to-date average balances of Savings, NOW, MMA and Wealth Management deposits, an increase in the year-to-date average balance of net free funds of $73 million, an increase in the year-to-date average balance of wholesale borrowings (primarily repurchase agreements) of $148 million, reduced year-to-date average balances of liquidity management assets and other earning assets of $224 million, offset by decreases in the year-to-date average balance of retail certificates of deposit of $340 million and brokered certificates of deposit of $34 million.

NON-INTEREST INCOME

For the third quarter of 2008, non-interest income totaled $21.9 million and increased $10.4 million compared to the third quarter of 2007. The increase was primarily attributable to mortgage banking revenue, fees from covered call options, service charges on deposit accounts, gains on sales of premium finance receivables and gains on available for sale securities. Offsetting these increases were lower levels of wealth management revenue and lower revenue from Bank Owned Life Insurance.

Wealth management is comprised of the trust and asset management revenue of Wayne Hummer Trust Company and the asset management fees, brokerage commissions, trading commissions and insurance product commissions at Wayne Hummer Investments and Wayne Hummer Asset Management Company. Wealth management totaled $7.0 million in the third quarter of 2008 and $7.6 million in the third quarter of 2007. Decreased asset valuations due to the recent equity market declines have hindered the revenue growth from trust and asset management activities. Continued uncertainties surrounding the equity markets overall have slowed the growth of the brokerage component of wealth management revenue.

Mortgage banking includes revenue from activities related to originating, selling and servicing residential real estate loans for the secondary market. For the quarter ended September 30, 2008, this revenue source totaled $4.5 million, an increase of $7.6 million when compared to the third quarter of 2007. The mortgage banking revenue recorded in the third quarter of 2007 included $5.5 million for estimated losses related to recourse obligations on residential mortgage loans sold to investors and $1.2 million fair market value adjustment on residential mortgage loans held for sale. Future growth of mortgage banking is impacted by the interest rate environment and current residential housing conditions and will continue to be dependent upon both. A continuation of the existing depressed residential real-estate environment may hamper mortgage banking production growth.

Service charges on deposit accounts totaled $2.7 million for the third quarter of 2008, an increase of $535,000, or 25%, when compared to the same quarter of 2007. The majority of deposit service charges relates to customary fees on overdrawn accounts and returned items. The level of service charges received is substantially below peer group levels, as management believes in the philosophy of providing high quality service without encumbering that service with numerous activity charges.

Wintrust sold $35 million of premium finance receivables in the third quarter of 2008, recognizing $456,000 of net gains. There were no gains recorded in the third quarter of 2007 on sales of premium finance receivables or on

clean-up calls of previous sales. Sales of these receivables in future quarters are dependent upon an improvement in the market conditions impacting both sales of these loans and the opportunity for securitizing these loans as well as capital management considerations.

The administrative services revenue contributed by Tricom added $803,000 to total non-interest income in the third quarter of 2008 and $980,000 in the third quarter of 2007. This revenue comprises income from administrative services, such as data processing of payrolls, billing and cash management services, to temporary staffing service clients located throughout the United States. Tricom also earns interest and fee income from providing high-yielding, short-term accounts receivable financing to this same client base, which is included in the net interest income category. Growth of this revenue source continues to be hampered by competitive pricing and the current economic conditions.

Other non-interest income for the third quarter of 2008 totaled $5.5 million compared to $4.0 million in the third quarter of 2007. The largest components of the increase in other income were fees from certain covered call option transactions increasing $2.7 million in the third quarter of 2008 compared the same period of 2007. Management has been able to effectively use the proceeds from selling covered call options to offset net interest margin compression and administers such sales in a coordinated process with the Company’s overall asset/liability management. The covered call option contracts are written against certain U.S. Treasury and agency securities held in the Company’s portfolio for liquidity and other purposes. The interest rate environment continues to be conducive to increased covered call option transaction revenue. To date, the Company has recorded $6.2 million of covered call option income in the fourth quarter of 2008. The decrease in Bank Owned Life Insurance revenue in the third quarter of 2008 compared to the third quarter of 2007 is directly attributable to a death benefit of $1.4 million received in the third quarter of 2007.

N/M = Not Meaningful

For the nine months ended September 30, 2008, non-interest income totaled $79.5 million and increased $27.4 million compared to the same period in 2007.

The largest component of the year-to-date increase, fees from covered call options, increased $20.7 million compared to 2007. So far in 2008, compression in the net interest margin was effectively offset, as has consistently been the case, by the Company’s covered call strategy. An illustration of the past effectiveness of this strategy is shown in the Supplemental Financial Information section (see page titled “Net Interest Margin (Including Call Option Income).”) Mortgage banking revenue increased in 2008 primarily as a result of the charges recorded in the third quarter of 2007 that decreased reported revenue at that time. Miscellaneous revenue has decreased in 2008 primarily as a result of $1.2 million of net losses recorded on certain equity based limited partnership investments.

NON-INTEREST EXPENSE

Non-interest expense for the third quarter of 2008 totaled $63.0 million and increased approximately $3.5 million, or 6%, from the third quarter 2007 total of $59.5 million.

The following table presents non-interest expense by category for the three months ended September 30, 2008 and 2007:

Total other		10,276		9,137		1,139			12


Total non-interest expense	$	62,984	$	59,487		3,497			6

Salary and employee benefits expense increased $1.6 million, or 5%, in the third quarter of 2008 when compared to the third quarter of 2007. Base salary increases made up the largest portion of this increase.

Equipment, occupancy and data processing have all been directly impacted by the additional and expanded banking locations in the past 12 months. In the third quarter of 2008, equipment cost increased $140,000, or 4%, while occupancy cost increased $363,000, or 7%, over the third quarter of 2007. Additionally, data processing increased $205,000, or 8%, while professional fees increased $438,000, or 25%, primarily as a result of increased legal costs related to non-performing assets.

Total other expenses increased $1.1 million in the third quarter of 2008 compared to the third quarter of 2007. In addition to the components listed in the table above, this category is comprised of expenses such as ATM expenses, correspondent banking charges, directors fees, telephone, travel and entertainment, corporate insurance and dues and subscriptions. Increased FDIC insurance due to a higher rate structure imposed on all financial institutions by the FDIC in the first quarter 2007 accounted for $277,000 of the increase. The Company’s banks, like most banks, received credits for overcharges by the FDIC in the past few years, effectively reducing their premiums. While most of the Company’s banks received and used these credits during the first three quarters of 2007, the total amount of credits received by the Company was less than other bank holding companies related to the fact that most of the Company’s banks are de novo operations started in the last 16 years. The largest component of the miscellaneous expense increase of $673,000 was an increase of $257,000 in other real estate owned expenses.

Total non-interest expense	$	190,402	$	179,369		11,033			6

Non-interest expense for the first nine months of 2008 totaled $190.4 million and increased approximately $11.0 million, or 6%, from the 2007 total of $179.4 million. Salary and employee benefits, professional fees, FDIC insurance and other expenses recorded the largest increases. Professional fees increased $1.4 million, or 29%, primarily as a result of increased legal costs related to non-performing assets. Miscellaneous expenses increased $2.1 million, or 13%, primarily due to a $514,000 increase in expenses related to other real estate owned and approximately $1.4 million reduction in deferred loan origination costs (in accordance with FAS 91) primarily due to the adoption of FAS 159 on January 1, 2008 for Mortgages Held for Sale originated by the Company’s mortgage subsidiary. Origination costs are no longer deferred on mortgage loans originated for sale at this subsidiary with the impact being higher current operating expenses (as reflected in the miscellaneous expense component) offset by higher levels of gains recognized on the sale of the loans to the end investors (due to the lower cost basis of the loan).

The allowance for credit losses is comprised of the allowance for loan losses and the allowance for lending-related commitments. The allowance for loan losses is a reserve against loan amounts that are actually funded and outstanding while the allowance for lending-related commitments relates to certain amounts that Wintrust is committed to lend but for which funds have not yet been disbursed. The allowance for lending-related commitments (separate liability account) represents the portion of the provision for credit losses that was associated with unfunded lending-related commitments. The provision for credit losses may contain both a component related to funded loans (provision for loan losses) and a component related to lending-related commitments (provision for unfunded loan commitments and letters of credit).

These balances totaled $0 as of September 30, 2008, $0.2 million as of June 30, 2008, and $2.0 million as of December 31, 2007. Residential mortgage loans held for sale are accounted for at lower of aggregate cost or fair value, with valuation changes included as adjustments to non-interest income.

The provision for credit losses totaled $24.1 million for the third quarter of 2008, $10.3 million in the second quarter of 2008 and $4.4 million for the third quarter of 2007. For the quarter ended September 30, 2008, net charge-offs totaled $15.4 million compared to $6.4 million in the second quarter of 2008 and $3.0 million recorded in the third quarter of

2007. On a ratio basis, annualized net charge-offs as a percentage of average loans were 0.84% in the third quarter of 2008, 0.36% in the second quarter of 2008 and 0.17% in the third quarter of 2007.

On a year-to-date basis, provision for credit losses totaled $43.0 million for the first nine months of 2008 compared to $8.7 million in the first nine months of 2007. Net charge-offs totaled $27.0 million, or 0.50% of average loans on an annualized basis in the first nine months of 2008, compared to $6.0 million, or 0.12% of average loans on an annualized basis in the first nine months of 2007.

Management believes the allowance for loan losses is adequate to provide for inherent losses in the portfolio. There can be no assurances however, that future losses will not exceed the amounts provided for, thereby affecting future results of operations. The amount of future additions to the allowance for loan losses will be dependent upon management’s assessment of the adequacy of the allowance based on its evaluation of economic conditions, changes in real estate values, interest rates, the regulatory environment, the level of past-due and non-performing loans, and other factors. The increase from the end of the prior quarter reflects the continued economic weaknesses in the Company’s markets and is the result of an individual review of a significant number of individual credits as well as the overall risk factors impacting certain types of credits, specifically credits with residential development collateral valuation exposure.

Non-performing Residential Real Estate and Home Equity

The non-performing residential real estate and home equity loans totaled $7.3 million as of September 30, 2008 compared to $3.6 million at June 30, 2008 and $4.6 million as of September 30, 2007. The September 30, 2008 non-performing balance is comprised of $6.0 million of residential real estate (one credit of $3.3 million and 16 individual credits totaling $2.7 million) and $1.3 million of home equity loans (16 individual credits). On average, this is approximately two non-performing residential real estate loans and home equity loans per chartered bank within the Company. The Company believes control and collection of these loans is very manageable. At this time, management does not expect any material losses from the resolution of any of the credits in this category.

Non-performing Commercial, Consumer and Other

The commercial, consumer and other non-performing loan category totaled $88.1 million as of September 30, 2008 compared to $64.1 million as of June 30, 2008 and $22.7 million as of September 30, 2007.

Management is pursuing the resolution of all credits in this category. However, given the current state of the residential real estate market, resolution of certain credits could span a lengthy period of time until market conditions stabilize. However, management believes reserves are adequate to absorb inherent losses that may occur upon the ultimate resolution of these credits.

Non-performing Loan Composition

The $95.4 million of non-performing loans classified as residential real estate and home equity, commercial, consumer, and other consumer consists of $39.1 million of residential real estate construction and land development related loans, $5.9 million of commercial related loans, $19.2 million of commercial real estate related loans, $17.5 million of commercial real estate construction and land development related loans, $13.4 million of residential real estate and home equity related loans and $269,000 of consumer related loans. Twelve of these relationships exceed $2.5 million in outstanding balances, approximating $69.1 million in total outstanding balances.

Non-performing Premium Finance Receivables

The table below presents the level of non-performing premium finance receivables as of September 30, 2008 and 2007, and the amount of net charge-offs for the quarters then ended.


(Dollars in thousands)	September 30, 2008			September 30, 2007
Non-performing premium finance receivables	$	16,142		$	18,604
- as a percent of premium finance receivables outstanding		1.34	%		1.44	%

Net charge-offs of premium finance receivables	$	884		$	510
- annualized as a percent of average premium finance receivables		0.29	%		0.16	%

As noted below, fluctuations in this category may occur due to timing and nature of account collections from insurance carriers. Although non-performing balances and net charge-offs in this category have increased over the past 12 months, the Company’s underwriting standards, regardless of the condition of the economy, have remained consistent. We anticipate that net charge-offs and non-performing asset levels in the near term will continue to be at levels that are within acceptable operating ranges for this category of loans. Management is comfortable with administering the collections at this level of non-performing premium finance receivables.

The ratio of non-performing premium finance receivables fluctuates throughout the year due to the nature and timing of canceled account collections from insurance carriers. Due to the nature of collateral for premium finance receivables it customarily takes 60-150 days to convert the collateral into cash collections. Accordingly, the level of non-performing premium finance receivables is not necessarily indicative of the loss inherent in the portfolio. In the event of default, Wintrust has the power to cancel the insurance policy and collect the unearned portion of the premium from the insurance carrier. In the event of cancellation, the cash returned in payment of the unearned premium by the insurer should generally be sufficient to cover the receivable balance, the interest and other charges due. Due to notification requirements and processing time by most insurance carriers, many receivables will become delinquent beyond 90 days while the insurer is processing the return of the unearned premium. Management continues to accrue interest until maturity as the unearned premium is ordinarily sufficient to pay-off the outstanding balance and contractual interest due.

Non-performing Indirect Consumer Loans

Total non-performing indirect consumer loans were $1.5 million at September 30, 2008, compared to $860,000 at June 30, 2008 and $871,000 at September 30, 2007. The ratio of these non-performing loans to total indirect consumer loans was 0.75% at September 30, 2008 compared to 0.39% at June 30, 2008 and 0.34% at September 30, 2007. As noted in the Allowance for Credit Losses table, net charge-offs as a percent of total indirect consumer loans were 0.49% for the quarter ended September 30, 2008 compared to 0.32% in the same period in 2007. The level of non-performing and net charge-offs of indirect consumer loans continue to be below standard industry ratios for this type of lending.

At the beginning of the third quarter the Company ceased the origination of indirect automobile loans. This niche business has served the Company well over the past 12 years in helping de-novo banks quickly, and profitably, grow into their physical structures. Competitive pricing pressures have significantly reduced the long-term potential profitably of this niche business. Given the current economic environment, the retirement of the founder of this niche business and the distinct possibility of rising interest rates over the longer-term, exiting the origination of this business was deemed to be in the best interest of the Company at this time. The Company will continue to service its existing portfolio during the duration of the credits and does not anticipate any change in historical credit trends for this niche business given this decision.

FORWARD-LOOKING STATEMENTS

This document contains forward-looking statements within the meaning of federal securities laws. Forward-looking information in this document can be identified through the use of words such as “may,” “will,” “intend,” “plan,” “project,” “expect,” “anticipate,” “should,” “would,” “believe,” “estimate,” “contemplate,” “possible,” and “point.” The forward-looking information is premised on many factors, some of which are outlined below. The Company intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and is including this statement for purposes of invoking these safe harbor provisions. Such forward-looking statements may be deemed to include, among other things, statements relating to the Company’s projected growth, anticipated improvements in earnings, earnings per share and other financial performance measures, and management’s long-term performance goals, as well as statements relating to the anticipated effects on financial results of condition from expected developments or events, the Company’s business and growth strategies, including anticipated internal growth, plans to form additional de novo banks and to open new branch offices, and to pursue additional potential development or acquisitions of banks, wealth management entities or specialty finance businesses. Actual results could differ materially from those addressed in the forward-looking statements as a result of numerous factors, including the following:

	•		Competitive pressures in the financial services business which may affect the pricing of the Company’s loan and deposit products as well as its services (including wealth management services).

	•		Changes in the interest rate environment, which may influence, among other things, the growth of loans and deposits, the quality of the Company’s loan portfolio, the pricing of loans and deposits and interest income.

	•		The extent of defaults and losses on our loan portfolio.

	•		Unexpected difficulties or unanticipated developments related to the Company’s strategy of de novo bank formations and openings. De novo banks typically require 13 to 24 months of operations before becoming profitable, due to the impact of organizational and overhead expenses, the startup phase of generating deposits and the time lag typically involved in redeploying deposits into attractively priced loans and other higher yielding earning assets.

	•		The ability of the Company to obtain liquidity and income from the sale of premium finance receivables in the future and the unique collection and delinquency risks associated with such loans.

	•		Failure to identify and complete acquisitions in the future or unexpected difficulties or unanticipated developments related to the integration of acquired entities with the Company.

	•		Legislative or regulatory changes or actions, or significant litigation involving the Company.

	•		Changes in general economic conditions in the markets in which the Company operates.

	•		The ability of the Company to receive dividends from its subsidiaries.

	•		The loss of customers as a result of technological changes allowing consumers to complete their financial transactions without the use of a bank.

	•		The ability of the Company to attract and retain senior management experienced in the banking and financial services industries.

	•		The other risk factors set forth in the Company’s filings with the Securities and Exchange Commission.

Therefore, there can be no assurances that future actual results will correspond to these forward-looking statements. The reader is cautioned not to place undue reliance on any forward looking statement made by or on behalf of Wintrust.

(1)		Net revenue includes net interest income and non-interest income.

(2)		The core net interest margin excludes the effect of the net interest expense associated with Wintrust’s junior subordinated debentures and the interest expense incurred to fund common stock repurchases.

(3)		The net overhead ratio is calculated by netting total non-interest expense and total non-interest income, annualizing this amount, and dividing by that period’s total average assets. A lower ratio indicates a higher degree of efficiency.

(4)		The efficiency ratio is calculated by dividing total non-interest expense by tax-equivalent net revenue (less securities gains or losses). A lower ratio indicates more efficient revenue generation.

(5)		The allowance for credit losses includes both the allowance for loan losses and the allowance for lending-related commitments.

(6)		See “Supplemental Financial Measures/Ratios” for additional information on this performance measure/ratio.
