Wintrust Financial Corporation Reports Record Third Quarter 2016 Net Income, an Increase of 38% Over Prior Year, and Year-to-Date 2016 Net Income of $152.3 million, an Increase of 26% Over Prior Year

ROSEMONT, ILLINOIS – Wintrust Financial Corporation (“Wintrust” or “the Company”) (Nasdaq: WTFC) announced net income of $53.1 million or $0.92 per diluted common share for the third quarter of 2016 compared to net income of $50.0 million or $0.90 per diluted common share for the second quarter of 2016 and $38.4 million or $0.69 per diluted common share for the third quarter of 2015. The Company recorded net income of $152.3 million or $2.72 per diluted common share for the first nine months of 2016 compared to net income of $121.2 million or $2.29 per diluted common share for the same period of 2015.

Highlights of the Third Quarter of 2016 *:

• Total assets increased by 15% on an annualized basis and now exceed $25 billion.

• Total loans, excluding covered loans and mortgage loans held-for-sale, increased by $927 million, or 20% on an annualized basis, to $19.1 billion. Loan growth included $555 million of select performing loans acquired from an affiliate of GE Capital Franchise Finance, which was completed in mid-August.

• Total deposits increased by $1.1 billion, or 22% on an annualized basis, to $21.1 billion. Non-interest bearing deposit accounts comprise 27% of total deposits.

• Mortgage banking revenue remained strong, totaling $34.7 million during the third quarter as origination volumes increased to $1.3 billion in the third quarter compared to $1.2 billion in the second quarter.

• Net overhead ratio improved to 1.44% from 1.46% remaining below our stated goal of 1.50%.

• Non-performing loans as a percentage of total loans, excluding covered loans, decreased to 0.44% from 0.48% and the allowance for loan losses as a percentage of total non-performing loans, excluding covered loans, increased to 142% from 130%.

• Net interest income increased $9.4 million primarily as a result of earning assets growth. Although loan yields increased, net interest margin dropped 3 basis points primarily due to a decrease in yields on liquidity management assets brought about by market conditions.

• Gains on investment securities totaled $3.3 million.

• Recorded a $2.5 million negative fair value adjustment related to mortgage servicing rights assets.

• Recorded a $1.8 million charge related to outstanding legal disputes, including a $1.5 million adverse arbitration award relating to a previously disclosed claim.

* See "Supplemental Financial Measures/Ratios" on pages 10-11 for more information on non-GAAP measures.

Edward J. Wehmer, President and Chief Executive Officer, commented, “The growth engine at Wintrust continued its momentum into the third quarter as we recorded nearly $1 billion of asset growth while controlling operating expenses as evidenced by the improvement of our net overhead ratio to 1.44% for the quarter. All aspects of our business performed solidly in the third quarter as evidenced by our record level of net income. Continued strong loan growth and mortgage banking operations, improved credit quality metrics and an improved net overhead ratio fueled the record results this quarter."

Mr. Wehmer continued, “Excluding covered loans and mortgage loans held-for-sale, our loan portfolio grew by $927 million during the third quarter, which included $555 million of select performing loans and related relationships acquired from an affiliate of GE Capital Franchise Finance. The increased loan volumes offset compression in the net interest margin during the

1

quarter due to a reduction in yield on liquidity management assets, resulting in an increase in net interest income of $9.4 million. Our loan pipelines remain consistently strong and we are well positioned for rising interest rates in the future. Deposit growth continued to be strong in the third quarter of 2016 as deposits increased $1.1 billion and exceeded $21 billion as of the end of the third quarter. Total deposit growth included $343 million of growth from demand deposits, which now totals $5.7 billion and comprises 27% of our overall deposit base."

Commenting on credit quality, Mr. Wehmer noted, “During the third quarter of 2016, the Company has continued its practice of timely addressing and resolving non-performing credits. Total non-performing assets, excluding covered assets, decreased by $8.0 million during the third quarter of 2016 resulting in non-performing assets as a percentage of total assets dropping from 0.52% to 0.47% during the period. Additionally, the allowance for loan losses as a percentage of non-performing loans, excluding covered loans, increased to 142% during the third quarter, exhibiting greater coverage for those non-performing credits. We believe that the Company's reserves remain appropriate."

Mr. Wehmer further commented, “Mortgage banking revenue in the third quarter totaled $34.7 million, a decrease of $2.1 million compared to the second quarter of 2016. Revenue for the third quarter of 2016 was negatively impacted by a $2.5 million valuation adjustment on mortgage servicing rights assets. Our mortgage operations experienced record origination volumes in the third quarter totaling $1.3 billion for the period compared to $1.2 billion during the second quarter of 2016. We expect normal seasonality in the fourth quarter, although our mortgage loan pipelines remain strong."

Turning to the future, Mr. Wehmer stated, “Wintrust is continuing 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. We expect continued growth and momentum in all areas of our business. The acquisition of select performing loans from an affiliate of GE Capital Franchise Finance is expected to help expand our franchise lending business. Also, the previously announced acquisition of First Community Financial Corporation located in Elgin, Illinois is expected to be completed in the fourth quarter of 2016. 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."

(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) 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.”

EARNINGS PER SHARE

The following table shows the computation of basic and diluted earnings per share for the periods indicated:

		Three Months Ended						Nine Months Ended
(In thousands, except per share data)		September 30, 2016		June 30, 2016		September 30, 2015		September 30, 2016		September 30, 2015

Weighted average common shares and effect of dilutive potential common shares	(D)	55,726		53,105		52,207		53,694		51,799
Net income per common share:
Basic	(A/C)	$	0.96	$	0.94	$	0.71	$	2.84	$	2.39
Diluted	(B/D)	$	0.92	$	0.90	$	0.69	$	2.72	$	2.29

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.

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. 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.

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 and held-to-maturity 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, 2016, June 30, 2016 and September 30, 2015 were $1.6 million, $1.5 million and $1.2 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.

For the third quarter of 2016, net interest income totaled $184.6 million, an increase of $9.4 million as compared to the second quarter of 2016 and an increase of $19.1 million as compared to the third quarter of 2015. Net interest margin was 3.21% (3.24% on a fully tax-equivalent basis) during the third quarter of 2016 compared to 3.24% (3.27% on a fully tax-equivalent basis) during the second quarter of 2016 and 3.31% (3.33% on a fully tax-equivalent basis) during the third quarter of 2015. The reduction in net interest margin compared to the second quarter of 2016 is primarily the result of a decline in yields on mortgage-backed securities.

For the first nine months of 2016, net interest income totaled $531.4 million, an increase of $57.1 million as compared to the first nine months of 2015. Net interest margin was 3.25% (3.27% on a fully tax-equivalent basis) for the first nine months of 2016 compared to 3.36% (3.39% on a fully tax-equivalent basis) for the same period of 2015. The reduction in net interest margin compared to the first nine months of 2015 is primarily the result of a decline in loan yields, including less accretion recognized on purchased loans, and an increase on the rate of 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, 2016, June 30, 2016 and September 30, 2015 is as follows:

Static Shock Scenario	+200 Basis Points		+100 Basis Points		-100 Basis Points
September 30, 2016	19.6	%	10.1	%	(10.4	)%
June 30, 2016	16.9	%	8.9	%	(8.9	)%
September 30, 2015	15.6	%	8.0	%	(11.1	)%

Ramp Scenario	+200 Basis Points		+100 Basis Points		-100 Basis Points
September 30, 2016	7.8	%	3.9	%	(4.1	)%
June 30, 2016	7.0	%	3.5	%	(3.7	)%
September 30, 2015	6.7	%	3.6	%	(4.0	)%

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).

Notable contributions to the change in non-interest income are as follows:

The increase in wealth management revenue during the current period as compared to the second quarter of 2016 and third quarter of 2015 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.

The decrease in mortgage banking revenue in the current quarter as compared to the most recent quarter resulted primarily from a $2.5 million negative fair value adjustment on mortgage servicing rights assets ("MSRs") during the period as a result of actual prepayments in the third quarter of 2016 and higher projected prepayment speeds. Mortgage loans originated or purchased for sale remained steady during the period totaling $1.3 billion in the current quarter as compared to $1.2 billion in the second quarter of 2016 and $973.7 million in the third quarter of 2015. Mortgage banking revenue includes revenue from activities related to originating, selling and servicing residential real estate loans for the secondary market. Mortgage revenue is also impacted by changes in the fair value of MSRs as the Company does not hedge this change in fair value. The Company typically originates mortgage loans held-for-sale with associated MSRs either retained or released. The Company records MSRs at fair value on a recurring basis. The table below presents additional selected information regarding mortgage banking revenue for the respective periods.

(1) Production revenue represents revenue earned from the origination and subsequent sale of mortgages, including gains on loans sold and fees from originations, processing and other related activities, and excludes servicing fees, changes in the fair value of servicing rights and changes to the mortgage recourse obligation.

The increase in service charges on deposit accounts 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 as well as additional service charges on deposit accounts from acquired institutions.

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 2016 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, 2016, June 30, 2016 and September 30, 2015.

The increase in operating lease income in the current quarter compared to the prior period quarters is primarily related to growth in business from the Company's leasing divisions.

The increase in other non-interest income in the current quarter as compared to the second quarter of 2016 is primarily due to higher 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 and gains recognized on the purchase and sale of certain assets, partially offset by lower income on bank-owned life insurance.

Notable contributions to the change in non-interest expense are as follows:

Salaries and employee benefits expense increased in the current quarter compared to the second quarter of 2016 primarily as a result of increased staffing as the Company grows and higher commissions and incentive compensation on variable pay based arrangements. Salaries and employee benefits expense increased in the current quarter compared to the third quarter of 2015 primarily as a result of the addition of employees from acquisitions, increased staffing as the Company grows, higher commissions and incentive compensation on variable pay based arrangements and an increase in employee benefits (primarily payroll tax related).

The increase in advertising and marketing expenses during the current quarter compared to the second quarter of 2016 is primarily related to higher expenses from mass market media promotions. 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.

The increase in miscellaneous expenses in the current quarter as compared to the second quarter of 2016 is primarily a result of a $1.8 million charge related to outstanding legal disputes recognized during the period, including a $1.5 million adverse arbitration award relating to a previously disclosed claim arising out of the hiring of a wealth management financial advisor by Wayne Hummer Investments LLC. Miscellaneous expense includes such items as ATM expenses, correspondent bank charges, directors' fees, telephone, travel and entertainment, corporate insurance, dues and subscriptions, problem loan expenses, operating losses and lending origination costs that are not deferred.

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

22

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).

Net charge-offs as a percentage of loans, excluding covered loans, for the third quarter of 2016 totaled 12 basis points on an annualized basis compared to 11 basis points on an annualized basis in the second quarter of 2016 and 14 basis points on an annualized basis in the third quarter of 2015. Net charge-offs totaled $5.7 million in the third quarter of 2016, an $803,000 increase from $4.9 million in the second quarter of 2016 and remained steady when compared to the third quarter of 2015.

The provision for credit losses, excluding the provision for covered loan losses, totaled $9.7 million for the third quarter of 2016 compared to $9.3 million for the second quarter of 2016 and $8.7 million for the third quarter of 2015. The higher provision for credit losses in the third quarter of 2016 compared to the second quarter of 2016 was partly due to loan growth, excluding covered loans and mortgage loans held-for-sale, during the third quarter of 2016.

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.

The following table presents the provision for credit losses and allowance for credit losses by component for the periods presented:

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, 2016 and June 30, 2016.

The increase in the allowance for loan losses to core loans in the third quarter of 2016 compared to the second quarter of 2016 was attributable to $303.7 million core loan portfolio growth.

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 0.72% of the total loan portfolio as of September 30, 2016 and 0.78% of the total loan portfolio as of June 30, 2016.

As of September 30, 2016, $49.1 million of all loans, excluding covered loans, or 0.3%, were 60 to 89 days past due and $70.4 million, or 0.4%, were 30 to 59 days (or one payment) past due. As of June 30, 2016, $75.7 million of all loans, excluding covered loans, or 0.4%, were 60 to 89 days past due and $90.4 million, or 0.5%, were 30 to 59 days (or one payment) past due. The majority of the commercial and commercial real estate loans shown as 60 to 89 days and 30 to 59 days past due are included on the Company’s internal problem loan reporting system. Loans on this system are closely monitored by management on a monthly basis.

The Company’s home equity and residential loan portfolios continue to exhibit low delinquency ratios. Home equity loans at September 30, 2016 that are current with regard to the contractual terms of the loan agreement represent 98.0% of the total home equity portfolio. Residential real estate loans at September 30, 2016 that are current with regards to the contractual terms of the loan agreements comprise 97.5% of total residential real estate loans outstanding.

(1) As of the dates shown, no TDRs were past due greater than 90 days and still accruing interest.

(2) Non-accrual loans included TDRs totaling $14.8 million, $16.3 million, and $10.1 million as of September 30, 2016, June 30, 2016, and September 30, 2015, respectively.

29

The ratio of non-performing assets to total assets was 0.47% as of September 30, 2016, compared to 0.52% at June 30, 2016, and 0.63% at September 30, 2015. Non-performing assets, excluding covered assets, totaled $118.6 million at September 30, 2016, compared to $126.6 million at June 30, 2016 and $138.0 million at September 30, 2015. Non-performing loans, excluding covered loans, totaled $83.1 million, or 0.44% of total loans, at September 30, 2016 compared to $88.1 million, or 0.48% of total loans, at June 30, 2016 and $86.0 million, or 0.53% of total loans, at September 30, 2015. The decrease in non-performing loans, excluding covered loans, compared to June 30, 2016 is primarily the result of a $3.1 million decrease in the commercial premium finance receivables portfolio and a $1.8 million decrease in the commercial real estate loan portfolio. OREO, excluding covered OREO, of $35.1 million at September 30, 2016 decreased $3.0 million compared to $38.1 million at June 30, 2016 and decreased $16.8 million compared to $51.9 million at September 30, 2015.

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.

(1) Loan was previously classified as a troubled debt restructuring and subsequently performed in compliance with the loan’s modified terms for a period of six months (including over a calendar year-end) at a modified interest rate which represented a market rate at the time of restructuring. Per our TDR policy, the TDR classification is removed.

Each TDR was reviewed for impairment at September 30, 2016 and approximately $2.8 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 both the three months ending September 30, 2016 and 2015, the Company recorded $98,000 in interest income representing this decrease in impairment. For the nine months ended September 30, 2016 and 2015, the Company recorded $323,000 and $385,000, 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.

33

The following table provides a comparative analysis for the period end balances of covered assets and any changes in the allowance for covered loan losses. The Company expects covered assets and the allowance for covered loan losses to continue to decrease in periods without FDIC-assisted acquisitions.

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.

(2) Reclassification is the result of subsequent increases in expected principal cash flows.

(3) As of September 30, 2016, the Company estimates that the remaining accretable yield balance to be amortized to the indemnification asset for the bank acquisitions is $1.5 million. The remainder of the accretable yield related to bank acquisitions is expected to be amortized to interest income.

Accretion to interest income accounted for under ASC 310-30 totaled $6.4 million and $5.9 million in the third quarter of 2016 and 2015, respectively. For the nine months ended September 30, 2016 and 2015, the Company recorded accretion to interest income of $17.1 million and $18.4 million, respectively. These amounts include accretion from both covered and non-covered loans, and are included together within interest and fees on loans in the Consolidated Statements of Income.

FORWARD-LOOKING STATEMENTS

This document contains forward-looking statements within the meaning of federal securities laws. Forward-looking information can be identified through the use of words such as “intend,” “plan,” “project,” “expect,” “anticipate,” “believe,” “estimate,” “contemplate,” “possible,” “point,” “will,” “may,” “should,” “would” and “could.” Forward-looking statements and information are not historical facts, are premised on many factors and assumptions, and represent only management’s expectations, estimates and projections regarding future events. Similarly, these statements are not guarantees of future performance and involve certain risks and uncertainties that are difficult to predict, which may include, but are not limited to, those listed below and the Risk Factors discussed under Item 1A of the Company’s 2015 Annual Report on Form 10-K and in any of the Company’s subsequent SEC filings. 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 future financial performance, the performance of its loan portfolio, the expected amount of future credit reserves and charge-offs, delinquency trends, growth plans, regulatory developments, securities that the Company may offer from time to time, and management’s long-term performance goals, as well as statements relating to the anticipated effects on financial condition and results of operations from expected developments or events, the Company’s business and growth strategies, including future acquisitions of banks, specialty finance or wealth management businesses, internal growth and plans to form additional de novo banks or branch offices. Actual results could differ materially from those addressed in the forward-looking statements as a result of numerous factors, including the following:

• difficult economic conditions have adversely affected our company and the financial services industry in general and further deterioration in economic conditions may materially adversely affect our business, financial condition, results of operations and cash flows;

37

• since our business is concentrated in the Chicago metropolitan and southern Wisconsin market areas, further declines in the economy of this region could adversely affect our business;

• if our allowance for loan losses is not sufficient to absorb losses that may occur in our loan portfolio, our financial condition and liquidity could suffer;

• a significant portion of our loan portfolio is comprised of commercial loans, the repayment of which is largely dependent upon the financial success and economic viability of the borrower;

• a substantial portion of our loan portfolio is secured by real estate, in particular commercial real estate. Deterioration in the real estate markets could lead to additional losses, which could have a material adverse effect on our financial condition and results of operations;

• any inaccurate assumptions in our analytical and forecasting models could cause us to miscalculate our projected revenue or losses, which could adversely affect our financial condition;

• unanticipated changes in prevailing interest rates and the effects of changing regulation could adversely affect our net interest income, which is our largest source of income;

• our liquidity position may be negatively impacted if economic conditions continue to suffer;

• the financial services industry is very competitive, and if we are not able to compete effectively, we may lose market share and our business could suffer;

• if we are unable to compete effectively, we will lose market share and income from deposits, loans and other products may be reduced. This could adversely affect our profitability and have a material adverse effect on our business, financial condition and results of operations;

• if we are unable to continue to identify favorable acquisitions or successfully integrate our acquisitions, our growth may be limited and our results of operations could suffer;

• our participation in FDIC-assisted acquisitions may present additional risks to our financial condition and results of operations;

• an actual or perceived reduction in our financial strength may cause others to reduce or cease doing business with us, which could result in a decrease in our net interest income and fee revenues;

• if our growth requires us to raise additional capital, that capital may not be available when it is needed or the cost of that capital may be very high;

• disruption in the financial markets could result in lower fair values for our investment securities portfolio;

• our controls and procedures may fail or be circumvented;

• new lines of business and new products and services are essential to our ability to compete but may subject us to additional risks;

• failures of our information technology systems may adversely affect our operations;

• failures by or of our vendors may adversely affect our operations;

• we issue debit cards, and debit card transactions pose a particular cybersecurity risk that is outside of our control;

• we depend on the accuracy and completeness of information we receive about our customers and counterparties to make credit decisions;

• if we are unable to attract and retain experienced and qualified personnel, our ability to provide high quality service will be diminished, we may lose key customer relationships, and our results of operations may suffer;

• we are subject to environmental liability risk associated with lending activities;

• we are subject to claims and legal actions which could negatively affect our results of operations or financial condition;

• losses incurred in connection with actual or projected repurchases and indemnification payments related to mortgages that we have sold into the secondary market may exceed our financial statement reserves and we may be required to increase such reserves in the future. Increases to our reserves and losses incurred in connection with actual loan repurchases and indemnification payments could have a material adverse effect on our business, financial condition, results of operations or cash flows;

• consumers may decide not to use banks to complete their financial transactions, which could adversely affect our business and results of operations;

• we may be adversely impacted by the soundness of other financial institutions;

• de novo operations often involve significant expenses and delayed returns and may negatively impact Wintrust's profitability;

• we are subject to examinations and challenges by tax authorities, and changes in federal and state tax laws and changes in interpretation of existing laws can impact our financial results;

• changes in accounting policies or accounting standards could materially adversely affect how we report our financial results and financial condition;

• we are a bank holding company, and our sources of funds, including to pay dividends, are limited;

• anti-takeover provisions could negatively impact our shareholders;

• if we fail to meet our regulatory capital ratios, we may be forced to raise capital or sell assets;

• if our credit rating is lowered, our financing costs could increase;

• changes in the United States’ monetary policy may restrict our ability to conduct our business in a profitable manner;

• legislative and regulatory actions taken now or in the future regarding the financial services industry may significantly increase our costs or limit our ability to conduct our business in a profitable manner;

38

• financial reform legislation and increased regulatory rigor around mortgage-related issues may reduce our ability to market our products to consumers and may limit our ability to profitably operate our mortgage business;

• federal, state and local consumer lending laws may restrict our ability to originate certain mortgage loans or increase our risk of liability with respect to such loans and could increase our cost of doing business;

• regulatory initiatives regarding bank capital requirements may require heightened capital;

• our FDIC insurance premiums may increase, which could negatively impact our results of operations;

• non-compliance with the USA PATRIOT Act, Bank Secrecy Act or other laws and regulations could result in fines or sanctions;

• our premium finance business may involve a higher risk of delinquency or collection than our other lending operations, and could expose us to losses;

• widespread financial difficulties or credit downgrades among commercial and life insurance providers could lessen the value of the collateral securing our premium finance loans and impair the financial condition and liquidity of FIFC and FIFC Canada;

• regulatory changes could significantly reduce loan volume and impair the financial condition of FIFC; and

• our wealth management business in general, and WHI's brokerage operation, in particular, exposes us to certain risks associated with the securities industry.

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 the Company.
