Wintrust Financial Corporation Reports Third Quarter and Year-to-Date 2015 Net Income

ROSEMONT, ILLINOIS – Wintrust Financial Corporation (“Wintrust” or “the Company”) (Nasdaq: WTFC) announced net income of $38.4 million or $0.69 per diluted common share for the third quarter of 2015 compared to net income of $43.8 million or $0.85 per diluted common share for the second quarter of 2015 and $40.2 million or $0.79 per diluted common share for the third quarter of 2014. The Company recorded net income of $121.2 million or $2.29 per diluted common share for the first nine months of 2015 compared to net income of $113.3 million or $2.23 per diluted common share for the same period of 2014. Operating net income was $41.8 million or $0.75 per diluted common share for the third quarter of 2015 compared to $44.5 million or $0.86 per diluted common share in the second quarter of 2015. Operating net income excludes acquisition related charges totaling $5.7 million and $1.1 million in the third quarter of 2015 and second quarter of 2015, respectively. A table reconciling net income as reported to operating net income is set forth below and additional detail is shown in the "Supplemental Financial Measures/Ratios" section.

Highlights compared with the Second Quarter of 2015*:

• Total assets increased by 24% on an annualized basis to $22.0 billion

• Net interest margin decreased 8 basis points primarily as a result of lower yields on earning assets due to pricing pressure and the low rate environment

• Maintained strong capital ratios with a tangible common equity ratio, assuming full conversion of convertible preferred stock, of 8.0%

• Dividend on Series D preferred stock, issued in June 2015, reduced earnings per diluted common share by $0.04 per share

Edward J. Wehmer, President and Chief Executive Officer, commented, “Wintrust reported operating net income of $41.8 million for the third quarter of 2015 and operating net income of $125.8 million on a year-to-date basis. The third quarter of 2015 was characterized by continued strong loan and deposit growth coupled with compression in our net interest margin, stable credit quality metrics, decreased mortgage banking revenue, the acquisitions of North Bank, Suburban Illinois Bancorp, Inc. and Community Financial Shares, Inc. and the costs related to these acquisitions."

Mr. Wehmer continued, “Excluding covered loans and mortgage loans held-for-sale, we grew our loan portfolio by $803 million in the third quarter, which included $455 million of loans acquired in relation to the three bank acquisitions. This increase in loan volume helped offset the impact on net interest income from net interest margin compression experienced during the quarter from competitive pricing pressures and the continued low rate environment. Our average loan to deposit ratio declined to 91.9% in the third quarter of 2015 compared to 92.8% in the second quarter of 2015 as the three acquisitions combined had a loan to deposit ratio of only 56.7%. Our loan pipelines remain consistently strong. Deposits in the third quarter of 2015 increased $1.1 billion, which included $802 million assumed from the bank acquisitions during the period. Demand deposits increased $796 million and now comprise 26% of our overall deposit base compared to 23% at the end of the second quarter of 2015."

Commenting on credit quality, Mr. Wehmer noted, “Total non-performing assets increased by $19.2 million. This increase was comprised of $4.6 million of OREO related to the three acquisitions completed in July, $7.3 million transferring from covered OREO as the loss sharing period expired, a single customer relationship totaling $9.3 million being placed in nonaccrual status at quarter-end, and other activities. Excluding covered loans, non-performing loans as a percentage of total loans was 0.53% at the end of the third quarter. The allowance for loan losses as a percentage of non-performing loans, excluding covered loans,

2

remained strong at 120%, exhibiting sufficient coverage for non-performing credits. We believe that the Company's reserves remain appropriate."

Mr. Wehmer further commented, “Mortgage banking revenue in the third quarter totaled $27.9 million, a decrease of $8.1 million compared to the second quarter of 2015 and an increase of $1.2 million compared to the third quarter of 2014. The decrease from the second quarter to the third quarter of 2015 resulted from origination volumes declining to $973.7 million from $1.2 billion and unfavorable changes in product and channel mix, both combined with more competitive pricing. Our mortgage banking business remains well positioned for growth both organically and through acquisitions."

Turning to the future, Mr. Wehmer stated, “We anticipate approximately $4 million in additional charges related to the three previously announced acquisitions in July over the next two quarters as the conversions and integrations are completed. This is in addition to the $5.7 million of various charges incurred in the third quarter related to these acquisitions. The cost savings from these transactions have exceeded our initial expectations. We believe we have achieved approximately two-thirds of our expected annual cost savings to date and expect to realize additional annual cost savings of approximately $5 million by the end of the first quarter of 2016. We remain on track to realize cost savings opportunities in the future from our existing infrastructure as additional acquisition opportunities exist in all areas of our business lines. Evaluating strategic acquisitions and organic branch growth will continue to be a part of our overall growth strategy with the goal of becoming Chicago’s bank and Wisconsin’s bank. Our opportunities for both internal growth and external growth remain consistently strong. We continue to take a steady and measured approach to achieve our main objectives of growing franchise value, increasing profitability, leveraging our expense infrastructure and increasing shareholder value."

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

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

(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 average total 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) 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, a 5% growth rate for a quarter would represent an annualized 20% growth rate. Additional supplemental financial information showing quarterly trends can be found on the Company’s web site at www.wintrust.com by choosing “Financial Reports” under the “Investor Relations” heading, and then choosing “Financial Highlights.”

Financial Performance Overview – Third Quarter 2015

For the third quarter of 2015, net interest income totaled $165.5 million, an increase of $8.6 million as compared to the second quarter of 2015 and an increase of $13.9 million as compared to the third quarter of 2014. The changes in net interest income on both a sequential and linked quarter basis are the result of the following:

• Net interest income increased $8.6 million in the third quarter of 2015 compared to the second quarter of 2015, due to:

◦ An increase in total interest income of $10.1 million resulting primarily from loan growth during the period and one additional day of interest, partially offset by a reduction in yield on earning assets.              

◦ Interest expense increased $1.5 million primarily as a result of an increase in the average balance of interest-bearing liabilities, a two basis point increase in the rate on average interest bearing liabilities and one additional day in the quarter.

◦ Combined, the increase in interest income of $10.1 million and the increase in interest expense of $1.5 million created the $8.6 million increase in net interest income.

• Net interest income increased $13.9 million in the third quarter of 2015 compared to the third quarter of 2014, due to:

◦ Average loans, excluding covered loans, increased by $2.1 billion. The growth in average loans, excluding covered loans, was partially offset by a 17 basis point decline in the yield on earning assets, resulting in an increase in total interest income of $14.7 million.

◦ An increase in interest bearing deposits, an increase in borrowings under the Company's term credit facility at the end of the second quarter of 2015 and the completion of the Canadian secured borrowing transaction at the end of the fourth quarter of 2014 resulted in a $834,000 increase in interest expense.

◦ Combined, the increase in interest income of $14.7 million and the increase in interest expense of $834,000 created the $13.9 million increase in net interest income.

The net interest margin, on a fully taxable equivalent basis, for the third quarter of 2015 was 3.33% compared to 3.41% for the second quarter of 2015 and 3.46% for the third quarter of 2014. The reduction in net interest margin, on a fully taxable equivalent basis, compared to the second quarter of 2015 and third quarter of 2014 is primarily the result of a decline in yields on loans and other earning assets (see "Net Interest Income" section later in this release for further detail).

Non-interest income totaled $65.0 million in the third quarter of 2015, decreasing $12.1 million, or 16%, compared to the second quarter of 2015 and increasing $7.0 million, or 12%, compared to the third quarter of 2014. The decrease in non-interest income in the third quarter of 2015 compared to the second quarter of 2015 is primarily attributable to lower mortgage banking revenue, the recognition of a $1.5 million bank owned life insurance ("BOLI") death benefit in the second quarter of 2015 and lower fees from covered call option contracts, partially offset by increased service charges on deposits. The increase in non-interest income in the third quarter of 2015 compared to the third quarter of 2014 was primarily attributable to an increase in mortgage banking revenues, fees from covered call options, higher customer interest rate swap fees and an increase in service charges on deposits (see "Non-Interest Income" section later in this release for further detail).

Non-interest expense totaled $160.0 million in the third quarter of 2015, increasing $5.7 million, or 4%, compared to the second quarter of 2015 and increasing $21.5 million, or 16%, compared to the third quarter of 2014. The increase in the current quarter compared to the second quarter of 2015 can be primarily attributed to an increase in acquisition related charges, higher salary and employee benefit costs caused by the addition of employees from the various acquisitions and higher staffing levels as the Company grows, increased data processing expenses, partially offset by a decrease in OREO expenses. The increase in the third quarter of 2015 compared to the third quarter of 2014 was primarily attributable to acquisition related charges in the current quarter, higher salary and employee benefit costs caused by the addition of employees from the various acquisitions and higher staffing levels as the Company grows as well as higher commissions and incentive compensation, increased equipment and occupancy, data processing and professional fees, and higher marketing expenses, partially offset by a decrease in OREO expenses (see "Non-Interest Expense" section later in this release for further detail).

Financial Performance Overview – First Nine Months of 2015

For the first nine months of 2015, net interest income totaled $474.3 million, an increase of $29.5 million as compared to the first nine months of 2014 as a result of the following:

• Average earning assets increased by $2.1 billion, primarily comprised of average loan growth, excluding covered loans, of $1.9 billion and an increase of $216.9 million in the average balance of liquidity management assets, partially offset by a decrease of $96.3 million in the average balance of covered loans. The growth in average total loans, excluding covered loans, included an increase of $691.0 million in commercial loans, $523.3 million in commercial real estate loans, $463.2 million in life insurance premium finance receivables, $99.3 million in mortgage loans held-for-sale, $88.6 million in commercial premium finance receivables and $78.1 million in home equity and other loans.

• The average earning asset growth of $2.1 billion, partially offset by a 20 basis point decrease in yield on earning assets, resulted in an increase in total interest income of $32.4 million.

• Funding mix remained relatively consistent as average demand deposits increased $982.2 million, average interest bearing deposits increased $789.3 million and average wholesale borrowings increased $125.2 million. The increase in average interest bearing liabilities, partially offset by a one basis point decline in rate during the current period, resulted in a $2.9 million increase in interest expense.

• Combined, the increase in interest income of $32.4 million and the increase in interest expense of $2.9 million created the $29.5 million increase in net interest income.

The net interest margin, on a fully taxable equivalent basis, for the first nine months of 2015 was 3.39% compared to 3.56% for the first nine months of 2014 (see "Net Interest Income" section later in this release for further detail).

Non-interest income totaled $206.5 million in the first nine months of 2015, increasing $48.9 million, or 31%, compared to the first nine months of 2014. The increase in non-interest income in the first nine months of 2015 compared to the first nine months of 2014 is primarily attributable to an increase in mortgage banking and wealth management revenues, fees from covered call options, the recognition of a $1.5 million BOLI death benefit, increased service charges and higher fees on customer interest rate swap transactions (see "Non-Interest Income" section later in this release for further detail).

Non-interest expense totaled $461.6 million in the first nine months of 2015, increasing $58.2 million, or 14%, compared to the first nine months of 2014. The increase in the first nine months of 2015 compared to the first nine months of 2014 was primarily attributable to acquisition related charges during the current year, higher salary and employee benefit costs caused by the addition of employees from the various acquisitions and larger staffing as the Company grows as well as higher commissions and incentive compensation, and increased equipment, occupancy, data processing and professional fees, and increased marketing expenses, partially offset by a decrease in OREO expenses (see "Non-Interest Expense" section later in this release for further detail).

Financial Performance Overview – Credit Quality

The ratio of non-performing assets to total assets was 0.63% as of September 30, 2015, compared to 0.57% at June 30, 2015, and 0.69% at September 30, 2014. Non-performing assets, excluding covered assets, totaled $138.0 million at September 30, 2015, compared to $118.9 million at June 30, 2015 and $131.7 million at September 30, 2014.

Non-performing loans, excluding covered loans, totaled $86.0 million, or 0.53% of total loans, at September 30, 2015, compared to $76.6 million, or 0.49% of total loans, at June 30, 2015 and $81.1 million, or 0.58% of total loans, at September 30, 2014. The increase in non-performing loans, excluding covered loans, compared to June 30, 2015 is primarily the result of a single customer relationship totaling $9.3 million being placed in nonaccrual status at quarter-end. Compared to September 30, 2014, the increase is primarily the result of a $2.7 million increase in the home equity loan portfolio, a $1.6 million increase in the commercial loan portfolio and a $1.3 million increase in the commercial real-estate portfolio. OREO, excluding covered OREO, of $51.9 million at September 30, 2015 increased $9.8 million compared to $42.1 million at June 30, 2015 and decreased $1.5 million compared to $50.4 million at September 30, 2014. The increase in OREO, excluding covered OREO, compared to June 30, 2015 is primarily the result of the addition of properties from acquisitions and properties transferring from covered OREO as the loss sharing period expired during the period.

The provision for credit losses, excluding the provision for covered loan losses, totaled $8.7 million for the third quarter of 2015 compared to $9.7 million for the second quarter of 2015 and $6.0 million for the third quarter of 2014. The higher provision for credit losses in the third quarter of 2015 compared to the same period of 2014 was partly due to loan growth since the prior period.

Net charge-offs as a percentage of loans, excluding covered loans, for the third quarter of 2015 totaled 14 basis points on an annualized basis compared to ten basis points on an annualized basis in the second quarter of 2015 and 19 basis points on an annualized basis in the third quarter of 2014. Net charge-offs totaled $5.7 million in the third quarter of 2015, a $1.8 million increase from $3.9 million in the second quarter of 2015 and a $1.3 million decrease from $7.0 million in the third quarter of 2014.

Excluding the allowance for covered loan losses, the allowance for credit losses at September 30, 2015 totaled $103.9 million, or 0.64% of total loans, compared to $101.1 million, or 0.65% of total loans, at June 30, 2015 and $91.8 million, or 0.65% of total loans, at September 30, 2014. The allowance for unfunded lending-related commitments totaled $926,000 as of September 30, 2015 compared to $884,000 as of June 30, 2015 and $822,000 as of September 30, 2014.

Potentially dilutive common shares can result from stock options, restricted stock unit awards, stock warrants, the Company’s convertible preferred stock and shares to be issued under the Employee Stock Purchase Plan and the Directors Deferred Fee and Stock Plan, being treated as if they had been either exercised or issued, computed by application of the treasury stock method. While potentially dilutive common shares are typically included in the computation of diluted earnings per share, potentially dilutive common shares are excluded from this computation in periods in which the effect would reduce the loss per share or increase the income per share. For diluted earnings per share, net income applicable to common shares can be affected by the conversion of the Company’s convertible preferred stock. Where the effect of this conversion would reduce the loss per share or increase the income per share, net income applicable to common shares is not adjusted by the associated preferred dividends. Due to weighted average share differences, when stated on a quarter and year-to-date basis, the earnings per share for the year ended September 30, 2015 does not equal the sum of the respective earnings per share for the three quarters then ended.

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

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

(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) Capital ratios for current quarter-end are estimated. As of January 1, 2015 capital ratios are calculated under the requirements of Basel III.

(6) The allowance for credit losses includes both the allowance for loan losses and the allowance for unfunded lending-related commitments, but excludes the allowance for covered loan losses.

(7) Total shareholders’ equity minus preferred stock and total intangible assets divided by total assets minus total intangible assets.

(8) Asset quality ratios exclude covered loans.

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), the efficiency ratio, tangible common equity ratio, tangible common book value per share and return on average tangible common equity. In addition, certain operating measures and ratios are adjusted for acquisition related charges. These operating measures and ratios include operating net income, the efficiency ratio, the net overhead ratio, return on average assets, return on average common equity, return on average tangible common equity and net income per diluted common share. 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 assets 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 considers the tangible common equity ratio and tangible book value per common share as useful measurements of the Company’s equity. The Company references the return on average tangible common equity as a measurement of profitability. Management considers operating net income, which is reported net income excluding acquisition related charges, as a useful measure of operating performance. Acquisition related charges are specific costs incurred by the Company as a result of an acquisition that are not expected to continue in subsequent periods. The Company excludes acquisition related charges from reported net income as well as certain operating measures and ratios noted above to provide better comparability between periods.

The following table presents 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 for the last five quarters.

(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 securities and available-for-sale securities reflects a tax-equivalent adjustment based on a marginal federal corporate tax rate of 35%. The total adjustments for the three months ended September 30, 2015, June 30, 2015 and September 30, 2014 were $1.2 million, $1.1 million and $828,000, respectively.

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

(4) Loans, net of unearned income, include loans 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) See “Supplemental Financial Measures/Ratios” for additional information on this performance ratio.

(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 securities and available-for-sale 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, 2015, and September 30, 2014 were $3.4 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 loans 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.

Interest Rate Sensitivity

As an ongoing part of its financial strategy, the Company attempts to manage the impact of fluctuations in market interest rates on net interest income. Management measures its exposure to changes in interest rates by modeling many different interest rate scenarios.

The following interest rate scenarios display the percentage change in net interest income over a one-year time horizon assuming increases of 100 and 200 basis points and a decrease of 100 basis points. The Static Shock Scenario results incorporate actual cash flows and repricing characteristics for balance sheet instruments following an instantaneous, parallel change in market rates based upon a static (i.e. no growth or constant) balance sheet. Conversely, the Ramp Scenario results incorporate management’s projections of future volume and pricing of each of the product lines following a gradual, parallel change in market rates over twelve months. Actual results may differ from these simulated results due to timing, magnitude, and frequency of interest rate changes as well as changes in market conditions and management strategies. The interest rate sensitivity for both the Static Shock and Ramp Scenario at September 30, 2015, June 30, 2015 and September 30, 2014 is as follows:

Static Shock Scenario	+200 Basis Points		+100 Basis Points		-100 Basis Points
September 30, 2015	15.6	%	8.0	%	(11.1	)%
June 30, 2015	14.8	%	7.3	%	(10.5	)%
September 30, 2014	13.7	%	6.2	%	(11.1	)%

Ramp Scenario	+200 Basis Points		+100 Basis Points		-100 Basis Points
September 30, 2015	6.7	%	3.6	%	(4.0	)%
June 30, 2015	6.4	%	3.3	%	(4.0	)%
September 30, 2014	5.0	%	2.6	%	(5.0	)%

These results indicate that the Company has positioned its balance sheet to benefit from a rise in interest rates. This analysis also indicates that the Company would benefit to a greater magnitude should a rise in interest rates be significant (i.e., 200 basis points) and immediate (Static Shock Scenario).

The significant changes in non-interest income for the quarter ended September 30, 2015 compared to the quarters ended June 30, 2015 and September 30, 2014 are discussed below.

Wealth management revenue totaled $18.2 million in the third quarter of 2015 compared to $18.5 million in the second quarter of 2015, a decrease of 1%, and $17.7 million in the third quarter of 2014, an increase of 3%. The decrease during the current period as compared to the second quarter of 2015 is primarily attributable to volatile market conditions and lower customer trading

25

activity in the current quarter. The increase during the current period as compared to the third quarter of 2014 is primarily attributable to growth in assets under management due to new customers. Wealth management revenue is comprised of the trust and asset management revenue of The Chicago Trust Company and Great Lakes Advisors and the brokerage commissions, managed money fees and insurance product commissions at Wayne Hummer Investments.

For the quarter ended September 30, 2015, mortgage banking revenue totaled $27.9 million, a decrease of $8.1 million, or 23%, when compared to the second quarter of 2015, and an increase of $1.2 million, or 4%, when compared to the third quarter of 2014. The decrease in mortgage banking revenue in the third quarter of 2015 as compared to the second quarter of 2015 resulted primarily from lower origination volumes in the current quarter. Mortgage loans originated or purchased for sale were $973.7 million in the current quarter as compared to $1.2 billion in the second quarter of 2015 and $904.8 million in the third quarter of 2014. Mortgage banking revenue includes revenue from activities related to originating, selling and servicing residential real estate loans for the secondary market.

Service charges on deposit accounts totaled $7.4 million in the third quarter of 2015, an increase of $929,000 and $1.3 million compared to the quarters ended June 30, 2015 and September 30, 2014, respectively. The increase in the current quarter is mostly a result of higher account analysis fees on deposit accounts which have increased as a result of the Company's commercial banking initiative and recent acquisitions.

Fees from covered call option transactions totaled $2.8 million for the third quarter of 2015, compared to $4.6 million for the second quarter of 2015 and $2.1 million for the third quarter of 2014. The Company has typically written call options with terms of less than three months against certain U.S. Treasury and agency securities held in its portfolio for liquidity and other purposes. Management has effectively entered into these transactions with the goal of economically hedging security positions and enhancing its overall return on its investment portfolio by using fees generated from these options to compensate for net interest margin compression. These option transactions are designed to mitigate overall interest rate risk and do not qualify as hedges pursuant to accounting guidance. Fees from covered call options decreased in the current quarter compared to the second quarter of 2015 primarily as a result of selling call options against a smaller value of underlying securities resulting in lower premiums received by the Company. There were no outstanding call option contracts at September 30, 2015, June 30, 2015 and September 30, 2014.

The Company recognized $135,000 of trading losses in the third quarter of 2015 compared to trading gains of $160,000 in the second quarter of 2015 and trading gains of $293,000 in the third quarter of 2014. Trading gains and losses recorded by the Company primarily result from fair value adjustments related to interest rate derivatives not designated as accounting hedges, primarily interest rate cap instruments that the Company uses to manage interest rate risk, specifically in the event of future increases in short-term interest rates. The change in value of the cap derivatives reflects the present value of expected cash flows over the remaining life of the caps. These expected cash flows are derived from the expected path for and a measure of volatility for short-term interest rates.

Other non-interest income totaled $8.8 million in the third quarter of 2015 compared to $11.4 million in the second quarter of 2015 and $5.3 million in the third quarter of 2014. Other non-interest income decreased in the third quarter of 2015 as compared to the second quarter of 2015, primarily due to lower net gains on partnership investments in the current quarter and from the Company recognizing a $1.5 million BOLI death benefit in the second quarter of 2015. Other non-interest income increased in the third quarter of 2015 as compared to the third quarter of 2014, primarily due to an increase in swap fee revenues resulting from interest rate hedging transactions related to both customer-based trades and the related matched trades with inter-bank dealer counterparties as well as higher net gains on partnership investments.

The significant changes in non-interest expense for the quarter ended September 30, 2015 compared to the quarters ended June 30, 2015 and September 30, 2014 are discussed below.

Salaries and employee benefits expense increased $3.3 million, or 4%, in the third quarter of 2015 compared to the second quarter of 2015. In addition to acquisition related charges of $1.7 million, the increase was primarily a result of a $5.1 million increase in salaries as a result of various acquisitions and additional staffing as the Company grows, partially offset by a $3.6 million

27

decrease in commissions and incentive compensation primarily attributable to lower commissions as a result of decreased mortgage loan origination volume. Salaries and employee benefits expense increased $11.8 million, or 14%, compared to the third quarter of 2014 primarily as a result of the $1.7 million in acquisition related charges during the period as well as an additional $6.2 million increase in salaries as a result of various acquisitions and additional staffing as the Company grows, a $1.9 million increase in commissions and incentive compensation primarily attributable to higher commissions as a result of increased mortgage loan origination volume, and a $2.0 million increase in employee benefits resulting from higher insurance costs.

Equipment expense totaled $8.9 million for the third quarter of 2015, an increase of $973,000 compared to the second quarter of 2015 and an increase of $1.3 million compared to the third quarter of 2014. The increase in the current quarter compared to the prior year quarter is primarily related to the impact of the recent acquisitions and increased software license fees and higher depreciation as a result of equipment purchases. Equipment expense includes depreciation on equipment, maintenance and repairs, equipment rental and software license fees.

Occupancy expense for the third quarter of 2015 was $12.1 million, an increase of $665,000, or 6%, compared to the second quarter of 2015 and an increase of $1.6 million, or 16%, compared to the same period in 2014. Occupancy expense increased in the current quarter compared to the prior quarter due to property taxes and additional depreciation expenses on owned locations, including those obtained in the Company's acquisitions. The increase in the current quarter as compared to the prior year quarter is primarily the result of increased rent expense on leased properties as well as additional depreciation expenses on owned locations including those obtained in the Company's acquisitions. Occupancy expense includes depreciation on premises, real estate taxes, utilities and maintenance of premises, as well as net rent expense for leased premises.

Data processing expenses totaled $8.1 million in the third quarter of 2015 compared to $6.1 million recorded in the second quarter of 2015 and $4.8 million recorded in the third quarter of 2014. The amount of data processing expenses incurred increased due to $2.7 million and $653,000 of additional expenses recorded in the third quarter of 2015 and the second quarter of 2015, respectively, related to bank acquisition transactions as well as overall growth of loan and deposit accounts.

Advertising and marketing expenses totaled $6.2 million in the third quarter of 2015, a decrease of $169,000 compared to the second quarter of 2015 and an increase of $2.7 million compared to the third quarter of 2014. The increase in the current quarter compared to the prior year quarter relates primarily to expenses for community-related advertisements and sponsorships. Marketing costs are incurred to promote the Company's brand, commercial banking capabilities, the Company's various products, to attract loans and deposits and to announce new branch openings as well as the expansion of the Company's non-bank businesses. The level of marketing expenditures depends on the type of marketing programs utilized which are determined based on the market area, targeted audience, competition and various other factors.

Professional fees for the third quarter of 2015 were $4.1 million, compared to $5.1 million for the second quarter of 2015 and $4.0 million in the third quarter of 2014. The decrease in professional fees in the current quarter as compared to the second quarter of 2015 is due to a decrease in legal expenses, including legal fees incurred in connection with acquisitions as well as lower professional tax preparation fees. The majority of legal work for the acquisitions completed early in the third quarter of 2015 was performed in prior quarters of 2015. These acquisition related professional fees totaled $335,000 in the third quarter of 2015 compared to $417,000 in the second quarter of 2015. Professional fees include legal, audit and tax fees, external loan review costs and normal regulatory exam assessments.

OREO expense totaled $(367,000) in the third quarter of 2015 compared to OREO expense of $841,000 recorded in the second quarter of 2015 and $581,000 recorded in the third quarter of 2014. OREO expense was lower in the current quarter compared to the quarter ended June 30, 2015 and September 30, 2014 primarily due to higher gains recorded on non-covered OREO sales in the current quarter and lower expenses to maintain OREO properties. OREO costs include all costs related to obtaining, maintaining and selling other real estate owned properties.

Miscellaneous expense in the third quarter of 2015 increased $302,000, or 2%, compared to the quarter ended June 30, 2015 and increased $1.4 million, or 10%, compared to the quarter ended September 30, 2014. The increase in the current quarter as compared to the prior year quarter is primarily a result of higher travel and entertainment expenses and increased costs related to insurance and donations. Miscellaneous expense includes ATM expenses, correspondent bank charges, directors' fees, telephone, travel and entertainment, corporate insurance, dues and subscriptions, problem loan expenses and lending origination costs that are not deferred.

Allowance for credit losses as a percentage of loans at period end	0.64		%	0.65		%	0.65		%

The allowance for credit losses, excluding the allowance for covered loan losses, is comprised of the allowance for loan losses and the allowance for unfunded lending-related commitments. The allowance for loan losses is a reserve against loan amounts that are actually funded and outstanding while the allowance for unfunded lending-related commitments (separate liability account) relates to certain amounts that Wintrust is committed to lend but for which funds have not yet been disbursed. The provision for credit losses, excluding the provision for covered loan 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).

The provision for credit losses, excluding the provision for covered loan losses, totaled $8.7 million for the third quarter of 2015 compared to $9.7 million for the second quarter of 2015 and $6.0 million for the third quarter of 2014. The higher provision for credit losses in the third quarter of 2015 compared to the same period of 2014 was primarily due to loan growth since the prior period.

Net charge-offs as a percentage of loans, excluding covered loans, for the third quarter of 2015 totaled 14 basis points on an annualized basis compared to ten basis points on an annualized basis in the second quarter of 2015 and 19 basis points on an annualized basis in the third quarter of 2014. Net charge-offs totaled $5.7 million in the third quarter of 2015, a $1.8 million increase from $3.9 million in the second quarter of 2015 and a $1.3 million decrease from $7.0 million in the third quarter of 2014.

Management believes the allowance for credit losses is appropriate 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 credit losses will be dependent upon management’s assessment of the appropriateness 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 Company also provides a provision for covered loan losses on covered loans and maintains an allowance for covered loan losses on covered loans. Please see “Covered Assets” later in this document for more detail.

As part of the regular quarterly review performed by management to determine if the Company’s allowance for loan losses is appropriate, an analysis is prepared on the loan portfolio based upon a breakout of core loans and consumer, niche and purchased loans. A summary of the allowance for loan losses calculated for the loan components in both the core loan portfolio and the consumer, niche and purchased loan portfolio was shown on the previous pages as of September 30, 2015 and June 30, 2015.

The decrease in the allowance for loan losses to core loans in the third quarter of 2015 compared to the second quarter of 2015 was attributable to a decrease in required ASC 310 reserves (specific reserves) within the core portfolio.

Current credit quality metrics are comparable to the pre-credit crisis levels reported between 2005 and 2008. However, we are able to carry a slightly lower ratio of allowance for loan losses to total loans than during the pre-credit crisis period as the result of the fact that the mix of the Company's loan portfolio is now more heavily weighted toward niche and purchased loans which historically require lower reserves. The niche and purchased components of our total loan portfolio now comprise 40% as compared to 23% of the total loan portfolio at December 31, 2005. Our current loan portfolio is comprised of a core portion totaling $9.7 billion with a 0.92% of allowance for loan losses and a niche and purchased component totaling $6.6 billion that requires 0.20% of allowance for loan losses.

Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date. In accordance with accounting guidance, credit deterioration on purchased loans is recorded as a credit discount at the time of purchase instead of as an increase to the allowance for loan losses. For analysis purposes, the Company has combined the non-accretable credit discounts recorded on purchased loans with the total allowance for loan losses in the previous tables to present the total credit reserves available on its loan portfolio. The total allowance for loan losses and non-accretable credit discounts on purchased loans was 0.82% of the total loan portfolio as of September 30, 2015 as compared to 0.74% as of June 30, 2015. The Company expects the total allowance for loan losses and non-accretable credit discounts on purchased loans to total loans ratio to increase in periods that have acquisitions and decrease in periods without acquisitions, based on the performance of the purchased loan portfolios.

Non-performing Commercial and Commercial Real Estate

Non-performing commercial and commercial real estate loans totaled $40.6 million as of September 30, 2015 compared to $29.3 million at June 30, 2015 and $37.8 million at September 30, 2014. The increase compared to June 30, 2015 is primarily the result of a single customer relationship totaling $9.3 million being placed in nonaccrual status at quarter-end.

Management is pursuing the resolution of all credits in this category. At this time, management believes reserves are appropriate to absorb inherent losses that are expected upon the ultimate resolution of these credits.

Non-performing Residential Real Estate and Home Equity

Non-performing home equity and residential real estate loans totaled $22.9 million as of September 30, 2015. The balance remained relatively unchanged compared to $22.3 million and $21.4 million at June 30, 2015 and September 30, 2014, respectively. The September 30, 2015 non-performing balance is comprised of $14.6 million of residential real estate (71 individual credits) and $8.4 million of home equity loans (50 individual credits). On average, this is approximately 8 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 believes reserves are adequate to absorb inherent losses that are expected upon the ultimate resolution of these credits.

Non-performing Commercial Insurance Premium Finance Receivables

The table below presents the level of non-performing property and casualty premium finance receivables as of September 30, 2015, June 30, 2015 and September 30, 2014 and the amount of net charge-offs for the quarters then ended.

	September 30,			June 30,			September 30,
(Dollars in thousands)	2015			2015			2014
Non-performing premium finance receivables - commercial	$	21,982		$	24,209		$	21,225
- as a percent of premium finance receivables - commercial outstanding	0.91		%	0.98		%	0.89		%
Net charge-offs of premium finance receivables - commercial	$	1,317		$	1,068		$	1,268
- annualized as a percent of average premium finance receivables - commercial	0.21		%	0.18		%	0.20		%

Fluctuations in this category may occur due to timing and nature of account collections from insurance carriers. 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 property and casualty premium finance receivables and believes reserves are adequate to absorb inherent losses that are expected upon the ultimate resolution of these credits.

Due to the nature of collateral for commercial premium finance receivables, it customarily takes 60-150 days to convert the collateral into cash. Accordingly, the level of non-performing commercial premium finance receivables is not necessarily indicative of the loss inherent in the portfolio. In the event of default, Wintrust has the right 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.

Each TDR was reviewed for impairment at September 30, 2015 and approximately $3.4 million of impairment was present and appropriately reserved for through the Company’s normal reserving methodology in the Company’s allowance for loan losses. For TDRs in which impairment is calculated by the present value of future cash flows, the Company records interest income representing the decrease in impairment resulting from the passage of time during the respective period, which differs from interest income from contractually required interest on these specific loans. For the three months ended September 30, 2015 and 2014, the Company recorded $98,000 and $294,000, respectively, in interest income representing this decrease in impairment. For the nine months ended September 30, 2015 and 2014, the Company recorded $385,000 and $529,000, respectively, in interest income.

Covered Assets

In conjunction with FDIC-assisted transactions, the Company entered into loss share agreements with the FDIC. These agreements cover realized losses on loans, foreclosed real estate and certain other assets and require the Company to record loss share assets and liabilities that are measured separately from the loan portfolios because they are not contractually embedded in the loans and are not transferable with the loans should the Company choose to dispose of them. Fair values at the acquisition dates were estimated based on projected cash flows available for loss-share based on the credit adjustments estimated for each loan pool and the loss share percentages. The loss share assets and liabilities are also separately measured from the related loans and foreclosed real estate and recorded on the Consolidated Statements of Condition. Subsequent to the acquisition date, reimbursements received from the FDIC for actual incurred losses will reduce any loss share assets. Reductions to expected losses, to the extent such reductions to expected losses are the result of an improvement to the actual or expected cash flows from the covered assets, will also reduce any loss share asset and, if necessary, increase any loss share liability when necessary reductions exceed the current value of the loss share asset. The increases in cash flows for the purchased loans are recognized as interest income prospectively. In accordance with clawback provisions included in loss share agreements with the FDIC, the Company may be required to reimburse the FDIC when actual losses are less than certain thresholds established for each loss share agreement. The balance of these estimated reimbursements in accordance with clawback provisions and any related amortization are adjusted periodically for changes in the expected losses on covered assets. Estimated reimbursements from clawback provisions are recorded as a reduction to the loss share asset or, if necessary, an increase to the loss share liability on the Consolidated Statements of Condition. The allowance for loan losses for loans acquired in FDIC-assisted transactions is determined without giving consideration to the amounts recoverable through loss share agreements (since the loss share agreements are separately accounted for and thus presented “gross” on the balance sheet). On the Consolidated Statements of Income, the provision for credit losses is reported net of changes in the amount recoverable under the loss share agreements.

The following table provides a comparative analysis for the period end balances of the covered asset components and any changes in the allowance for covered loan losses.

Changes in Accretable Yield

The excess of cash flows expected to be collected over the carrying value of loans accounted for under ASC 310-30 is referred to as the accretable yield and is recognized in interest income using an effective yield method over the remaining life of the pool of loans. The accretable yield is affected by:

• Changes in interest rate indices for variable rate loans accounted for under ASC 310-30 – Expected future cash flows are based on the variable rates in effect at the time of the regular evaluations of cash flows expected to be collected;

• Changes in prepayment assumptions – Prepayments affect the estimated life of loans accounted for under ASC 310-30 which may change the amount of interest income, and possibly principal, expected to be collected; and

• Changes in the expected principal and interest payments over the estimated life – Updates to expected cash flows are driven by the credit outlook and actions taken with borrowers. Changes in expected future cash flows from loan modifications are included in the regular evaluations of cash flows expected to be collected.

The following table provides activity for the accretable yield of loans accounted for under ASC 310-30.
