Wintrust Financial Corporation Reports Second Quarter 2021 Net Income of $105.1 million and Year-To-Date Net Income of $258.3 million

ROSEMONT, ILLINOIS – Wintrust Financial Corporation (“Wintrust”, “the Company”, "we" or "our") (Nasdaq: WTFC) announced net income of $105.1 million or $1.70 per diluted common share for the second quarter of 2021, a decrease in diluted earnings per common share of 33% compared to the first quarter of 2021 and an increase of 400% compared to the second quarter of 2020. The Company recorded net income of $258.3 million or $4.24 per diluted common share for the first six months of 2021 compared to net income of $84.5 million or $1.38 per diluted common share for the same period of 2020.

Highlights of the Second Quarter of 2021:

Comparative information to the first quarter of 2021

•Total loans, excluding Paycheck Protection Program ("PPP") loans, increased by $1.2 billion or 15%, on an annualized basis.

◦Core loans increased by $497 million and niche loans increased by $657 million primarily due to growth in the commercial insurance premium finance receivable portfolio. See Table 1 for more information.

•PPP loans declined by $1.4 billion in the second quarter of 2021 primarily as a result of processing forgiveness payments on PPP loan balances originated in 2020. As of June 30, 2021, approximately 81% of PPP loan balances originated in 2020 have been forgiven, approximately 12% of balances are in the forgiveness review or submission process, and approximately 7% of balances have not applied for forgiveness.

•Total assets increased by $1.1 billion.

•Total deposits increased by $932 million, including a $499 million increase in non-interest bearing deposits.

•Net interest income increased by $17.7 million primarily due to earning asset growth and increased PPP loan fee accretion.

◦In the second quarter of 2021, average loans and average investment securities increased by $642 million and $827 million, respectively, as compared to first quarter of 2021.

◦The Company recognized $25.2 million of PPP loan fee accretion in the second quarter of 2021 as compared to $19.2 million in the first quarter of 2021.

•Net interest margin increased by nine basis points primarily due to increased PPP loan fee accretion and a seven basis point decline on the rate paid on interest bearing deposits.

•Mortgage banking revenue decreased to $50.6 million for the second quarter of 2021 as compared to $113.5 million in the first quarter of 2021.

•Recorded a negative provision for credit losses of $15.3 million in the second quarter of 2021 as compared to a negative provision for credit losses of $45.3 million in the first quarter of 2021.

•Recorded net charge-offs of $1.9 million in the second quarter of 2021 as compared to net charge-offs of $13.3 million in the first quarter of 2021. Net charge-offs as a percentage of average total loans totaled two basis points in the second quarter of 2021 on an annualized basis as compared to 17 basis points on an annualized basis in the first quarter of 2021.

•The allowance for credit losses on our core loan portfolio is approximately 1.49% of the outstanding balance as of June 30, 2021, down from 1.62% as of March 31, 2021. See Table 12 for more information. The allowance for credit losses to nonaccrual loans increased to 367.6% at June 30, 2021 compared to 341.3% as of March 31, 2021.

•Non-performing loans declined to $87.7 million, or 0.27% of total loans, as of June 30, 2021 as compared to $99.1 million, or 0.30% of total loans, as of March 31, 2021.

•Tangible book value per common share (non-GAAP) increased to $56.92 as compared to $55.42 as of March 31, 2021. See Table 18 for reconciliation of non-GAAP measures.

•Closed on the previously announced sale of three branches in southwestern Wisconsin including $77 million of deposits, resulting in a net gain of $4.0 million recorded in other non-interest income.

Edward J. Wehmer, Founder and Chief Executive Officer, commented, "Wintrust reported net income of $105.1 million for the second quarter of 2021, down from $153.1 million in the first quarter of 2021. On a year-to-date basis, net income totaled $258.3 million for the first six months of 2021, up from $84.5 million in the first six months of 2020, a 206% increase. Additionally, the Company continues to grow as total assets of $46.7 billion as of June 30, 2021 increased by $1.1 billion as compared to March 31, 2021 and increased by $3.2 billion as compared to June 30, 2020. The second quarter of 2021 was characterized by strong organic loan growth, increased net interest income, a decline in mortgage banking revenue, a release of reserves as our credit quality and macroeconomic forecasts improved and a continued focus to increase franchise value in our market area."

Mr. Wehmer continued, "The Company experienced loan growth, excluding PPP loans, of $1.2 billion or 15%, on an annualized basis in the second quarter of 2021, including growth in its commercial, commercial real estate, residential real estate loans for investment, commercial insurance premium finance receivable and life insurance premium receivable portfolios. The loan growth was driven significantly by $563 million of growth in the commercial insurance premium finance receivable portfolio in part due to favorable market conditions for that portfolio. We are experiencing historically low commercial line of credit utilization and believe that a reversion to normal levels, coupled with robust loan pipelines, will materialize in future loan growth. Total deposits increased by $932 million as compared to the first quarter of 2021 including an increase in non-interest bearing deposits which now comprise 33% of total deposits. We continue to emphasize growing our franchise, including gathering low cost deposits, which we believe will drive value in the long term. Our loans to deposits ratio ended the quarter at 84.8% and we believe that we have sufficient liquidity to meet customer loan demand."

Mr. Wehmer commented, "Net interest income increased in the second quarter of 2021 primarily due to earning asset growth and increased PPP loan fee accretion. The Company recognized $25.2 million of PPP loan fee accretion in the second quarter of 2021 as compared to $19.2 million in the first quarter of 2021. Net interest margin improved by nine basis points in the second quarter of 2021 as compared to the first quarter of 2021 primarily due to increased PPP loan fee accretion and a seven basis point decline on the rate paid on interest bearing deposits. We continue to maintain excess liquidity and believe that deploying such liquidity could potentially increase our net interest margin. However, given the decline in long-term interest rates in the second quarter of 2021, we did not materially increase our investment portfolio due to the lack of adequate market returns."

Mr. Wehmer noted, “We recorded mortgage banking revenue of $50.6 million in the second quarter of 2021 as compared to $113.5 million in the first quarter of 2021. Loan volumes originated for sale in the second quarter of 2021 were $1.7 billion, down from $2.2 billion in the first quarter of 2021. Production margin in the second quarter of 2021 was impacted by lower gain on sale margins and a decline in the mortgage originations pipeline. Additionally, the Company recorded a $5.5 million decrease in the value of mortgage servicing rights related to changes in fair value model assumptions as compared to an $18.0 million increase recognized in the first quarter of 2021. We believe the third quarter of 2021 will provide another strong quarter for mortgage banking originations."

Commenting on credit quality, Mr. Wehmer stated, "The Company recorded a negative provision for credit losses of $15.3 million in the second quarter of 2021 related to both improving credit quality and macroeconomic forecasts. The level of non-performing loans decreased by $11.4 million primarily due to non-performing loan payments received during the quarter. Additionally, net charge-offs were limited totaling $1.9 million in the second quarter of 2021 as compared to $13.3 million in the first quarter of 2021. The allowance for credit losses on our core loan portfolio as of June 30, 2021 is approximately 1.49% of the outstanding balance. We believe that the Company’s reserves remain appropriate and we remain diligent in our review of credit."

Mr. Wehmer concluded, "Our second quarter of 2021 results continued to demonstrate the multi-faceted nature of our business model which we believe uniquely positions us to be successful. We expect to leverage our differentiated, diversified loan portfolio to outperform peers with respect to loan growth which should allow us to expand net interest income. We are focused on taking advantage of market opportunities to prudently deploy excess liquidity into earning assets including core and niche loans and investment securities while maintaining an interest rate sensitive asset portfolio. We are opportunistically evaluating the acquisition market which has been active for both banks and business lines of various sizes. Of course, we remain diligent in our consideration of acquisition targets and will be prudent in our decision-making, always seeking to minimize dilution. Finally, we evaluate our operating expense base on an ongoing basis to enhance future profitability."

The graphs below illustrate certain financial highlights of the second quarter of 2021 as well as historical financial performance. See "Supplemental Non-GAAP Financial Measures/Ratios" at Table 18 for additional information with respect to non-GAAP financial measures/ratios, including the reconciliations to the corresponding GAAP financial measures/ratios.

SUMMARY OF RESULTS:

BALANCE SHEET

Total asset growth of $1.1 billion in the second quarter of 2021 was primarily comprised of a $1.4 billion increase in interest bearing deposits with banks, a $1.2 billion increase in total loans, excluding PPP loans, and an $86 million increase in investment securities. These increases were partially offset by a $1.4 billion decrease in PPP loans and a $275 million decrease in mortgage loans held-for-sale. Total loans, excluding PPP loans, increased by $1.2 billion primarily due to growth in the commercial, commercial real estate, residential real estate loans for investment, commercial insurance premium finance receivable and life insurance premium receivable portfolios. The Company believes that the $4.7 billion of interest-bearing deposits with banks held as of June 30, 2021 provides sufficient liquidity to operate its business plan.

Total liabilities increased $970 million in the second quarter of 2021 resulting primarily from a $932 million increase in total deposits. The increase in deposits was primarily due to a $607 million increase in money market deposits and a $499 million increase in non-interest bearing deposits. The Company's loans to deposits ratio ended the quarter at 84.8%. Management believes in substantially funding the Company's balance sheet with core deposits and utilizes brokered or wholesale funding sources as appropriate to manage its liquidity position as well as for interest rate risk management purposes.

For more information regarding changes in the Company’s balance sheet, see Consolidated Statements of Condition and Tables 1 through 3 in this report.

NET INTEREST INCOME

For the second quarter of 2021, net interest income totaled $279.6 million, an increase of $17.7 million as compared to the first quarter of 2021 and an increase of $16.5 million as compared to the second quarter of 2020. The $17.7 million increase in net interest income in the second quarter of 2021 compared to the first quarter of 2021 was primarily due to earning asset growth and increased PPP loan fee accretion. The Company recognized $25.2 million of PPP loan fee accretion in the second quarter of 2021 as compared to $19.2 million in the first quarter of 2021. As of June 30, 2021, the Company had approximately $42.3 million of net PPP loan fees that have yet to be recognized in income, with approximately $24.0 million projected to be recognized in income in the second half of 2021. Such projection is based on current level yield assumptions primarily driven by the estimated timing of expected cash flow receipts related to forgiveness.

Net interest margin was 2.62% (2.63% on a fully taxable-equivalent basis, non-GAAP) during the second quarter of 2021 compared to 2.53% (2.54% on a fully taxable-equivalent basis, non-GAAP) during the first quarter of 2021 and down from 2.73% (2.74% on a fully taxable-equivalent basis, non-GAAP) during the second quarter of 2020. The net interest margin increase as compared to the prior quarter was primarily due to the seven basis point decrease in the rate paid on interest-bearing liabilities and a four basis point increase in the yield on earning assets partially offset by a two basis point decrease in the net free funds contribution. The decrease in the rate paid on interest-bearing liabilities in the second quarter of 2021 as compared to the prior quarter is primarily due to a seven basis point decrease in the rate paid on interest-bearing deposits primarily due to lower repricing of time deposits. The four basis point increase in the yield on earning assets in the second quarter of 2021 as compared to the first quarter of 2021 was primarily due to a 13 basis point increase in yield on liquidity management assets as a result of purchases of investment securities toward the end of the first quarter of 2021 and a three basis point increase in yield earned on loans.

For more information regarding net interest income, see Tables 4 through 8 in this report.

ASSET QUALITY

The allowance for credit losses totaled $304.1 million as of June 30, 2021, a decrease of $17.2 million as compared to $321.3 million as of March 31, 2021. The allowance for credit losses decreased primarily due to improvements in the macroeconomic forecast in addition to improvement in portfolio characteristics throughout the quarter. Notably, there was a decrease in the allowance for credit losses in the Commercial Real Estate portfolio primarily driven by improvement in the forecasts of the Commercial Real Estate Price Index and Baa Corporate Credit Spreads. Other key drivers of allowance for credit losses changes include, but are not limited to, decreases in COVID-19 related loan modifications and positive loan risk rating migrations.

A negative provision for credit losses totaling $15.3 million was recorded for the second quarter of 2021 compared to a negative provision of $45.3 million for the first quarter of 2021 and $135.1 million of expense for the second quarter of 2020. For more information regarding the provision for credit losses, see Table 11 in this report.

Management believes the allowance for credit losses is appropriate to account for expected credit losses. The Current Expected Credit Losses ("CECL") standard requires the Company to estimate expected credit losses over the life of the Company’s financial assets at a certain point in time. There can be no assurances, however, that future losses will not significantly exceed the amounts provided for, thereby affecting future results of operations. A summary of the allowance for credit losses calculated for the loan components in each portfolio as of June 30, 2021, March 31, 2021, and December 31, 2020 is shown on Table 12 of this report.

Net charge-offs totaled $1.9 million in the second quarter of 2021, an $11.4 million decrease from $13.3 million in the first quarter of 2021 and a $13.5 million decrease from $15.4 million in the second quarter of 2020. Net charge-offs as a percentage of average total loans totaled two basis points in the second quarter of 2021 on an annualized basis compared to 17 basis points on an annualized basis in the first quarter of 2021 and 20 basis points on an annualized basis in the second quarter of 2020. For more information regarding net charge-offs, see Table 10 in this report.

As of June 30, 2021, $19.3 million of all loans, or 0.1%, were 60 to 89 days past due and $73.9 million, or 0.2%, were 30 to 59 days (or one payment) past due. As of March 31, 2021, $28.0 million of all loans, or 0.1%, were 60 to 89 days past due and $151.7 million, or 0.5%, were 30 to 59 days (or one payment) past due. Many 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 real estate loan portfolios continue to exhibit low delinquency rates as of June 30, 2021. Home equity loans at June 30, 2021 that are current with regard to the contractual terms of the loan agreement represent 98.8% of the total home equity portfolio. Residential real estate loans at June 30, 2021 that are current with regards to the contractual terms of the loan agreements comprised 98.3% of total residential real estate loans outstanding. For more information regarding past due loans, see Table 13 in this report.

The outstanding balance of COVID-19 related modified loans totaled approximately $146 million or 0.5% of total loans, excluding PPP loans as of June 30, 2021 as compared to $254 million or 0.8% as of March 31, 2021. The most significant proportion of outstanding modifications changed terms to interest-only payments.

The ratio of non-performing assets to total assets was 0.22% as of June 30, 2021, compared to 0.25% at March 31, 2021, and 0.46% at June 30, 2020. Non-performing assets totaled $103.3 million at June 30, 2021, compared to $114.9 million at March 31, 2021 and $198.5 million at June 30, 2020. Non-performing loans totaled $87.7 million, or 0.27% of total loans, at June 30, 2021 compared to $99.1 million, or 0.30% of total loans, at March 31, 2021 and $188.3 million, or 0.60% of total loans, at June 30, 2020. The decrease in non-performing loans as of June 30, 2021 as compared to March 31, 2021 is primarily due to payments throughout the quarter. OREO totaled $15.6 million at June 30, 2021, a decrease of $241,000 compared to $15.8 million at March 31, 2021 and an increase of $5.4 million compared to $10.2 million at June 30, 2020. Management is pursuing the resolution of all non-performing assets. At this time, management believes OREO is appropriately valued at the lower of carrying value or fair value less estimated costs to sell. For more information regarding non-performing assets, see Table 14 in this report.

NON-INTEREST INCOME

Wealth management revenue increased by $1.4 million during the second quarter of 2021 as compared to the first quarter of 2021 primarily due to increased trust and asset management fees. Wealth management revenue is comprised of the trust and asset management revenue of The Chicago Trust Company and Great Lakes Advisors, the brokerage commissions, managed money fees and insurance product commissions at Wintrust Investments and fees from tax-deferred like-kind exchange services provided by the Chicago Deferred Exchange Company.

Mortgage banking revenue decreased by $62.9 million in the second quarter of 2021 as compared to the first quarter of 2021, primarily due to a $33.8 million decrease in production revenue from lower originations for sale and lower gain on sale margins and a $5.5 million unfavorable mortgage servicing rights portfolio fair value adjustment as compared to an $18.0 million increase recognized in the prior quarter related to changes in fair value model assumptions. Loans originated for sale were $1.7 billion in the second quarter of 2021, a decrease of $498.0 million as compared to the first quarter of 2021. The percentage of origination volume from refinancing activities was 47% in the second quarter of 2021 as compared to 73% in the first quarter of 2021. Mortgage banking revenue includes revenue from activities related to originating, selling and servicing residential real estate loans for the secondary market.

During the second quarter of 2021, the fair value of the mortgage servicing rights portfolio increased primarily due to the capitalization of $17.5 million of servicing rights partially offset by a reduction in value of $8.5 million due to payoffs and paydowns of the existing portfolio and a fair value adjustment decrease of $5.5 million. No economic hedges were outstanding relative to the mortgage servicing rights portfolio during the first or second quarter of 2021.

Operating lease income decreased by $2.2 million in the second quarter of 2021 as compared to the first quarter of 2021. The decrease is primarily due to a $1.5 million gain recognized on sale of lease assets in the first quarter of 2021.

Other non-interest income increased by $4.7 million in the second quarter of 2021 as compared to the first quarter of 2021 primarily due to a $4.0 million net gain recorded on the previously announced sale of three branches in southwestern Wisconsin.

For more information regarding non-interest income, see Tables 15 and 16 in this report.

NON-INTEREST EXPENSE

Salaries and employee benefits expense decreased by $8.0 million in the second quarter of 2021 as compared to the first quarter of 2021. The $8.0 million decrease is comprised of a decrease of $7.6 million in commissions and incentive compensation and a decrease of $412,000 in employee benefits expense. Salaries expense was effectively unchanged from the first quarter of 2021 to the second quarter of 2021. The decrease in commissions and incentive compensation is primarily due to lower commissions related to a decline in total mortgage originations for sale and investment.

Advertising and marketing expense totaled $11.3 million in the second quarter of 2021, an increase of $2.8 million as compared to the first quarter of 2021. The increase in the second quarter relates primarily to increased sponsorship activity for the summer months. Marketing costs are incurred to promote the Company's brand, commercial banking capabilities and 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 timing of sponsorship programs utilized which are determined based on the market area, targeted audience, competition and various other factors.

Miscellaneous expense in the second quarter of 2021 decreased by $55,000 as compared to the first quarter of 2021. The second quarter of 2021 included a $1.4 million reversal of contingent consideration expense related to the previous acquisition of mortgage operations as compared to a $937,000 reversal of contingent consideration expense in the first quarter of 2021. The liability for contingent consideration expense related to the previous acquisition of mortgage operations is based upon forward looking mortgage origination volumes and the estimated profitability of that operation. Should those assumptions change going forward, the liability may need to be increased or decreased. The contractual period covering contingent consideration ends in January 2023 and the final two years of the contract contemplate a lower ratio of contingent consideration relative to financial performance. Miscellaneous expense also 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.

For more information regarding non-interest expense, see Table 17 in this report.

INCOME TAXES

The Company recorded income tax expense of $39.0 million in the second quarter of 2021 compared to $53.7 million in the first quarter of 2021 and $9.0 million in the second quarter of 2020. The effective tax rates were 27.08% in the second quarter of 2021 compared to 25.97% in the first quarter of 2021 and 29.46% in the second quarter of 2020.

The slightly higher effective tax rate in the second quarter of 2021 as compared to the first quarter of 2021 was primarily due to the recognition of excess tax benefits on stock compensation in the first quarter, and the higher effective rate in the second quarter of 2020 as compared to the 2021 periods was primarily a result of a significantly reduced amount of pretax income in the period.

BUSINESS UNIT SUMMARY

Community Banking

Through its community banking unit, the Company provides banking and financial services primarily to individuals, small to mid-sized businesses, local governmental units and institutional clients residing primarily in the local areas the Company services. In the second quarter of 2021, this unit expanded its loan portfolio and its deposit portfolio. In addition, the segment's net interest margin increased in the second quarter of 2021 as compared to the first quarter of 2021.

Mortgage banking revenue was $50.6 million for the second quarter of 2021, a decrease of $62.9 million as compared to the first quarter of 2021 primarily due to a $33.8 million decrease in production revenue resulting from lower originations for sale and lower gain on sale margins and a $5.5 million decrease in the value of mortgage servicing rights related to changes in fair value model assumptions as compared to an $18.0 million favorable fair value adjustment in the prior quarter related to changes in fair value model assumptions. Service charges on deposit accounts totaled $13.2 million in the second quarter of 2021, an increase of $1.2 million as compared to the first quarter of 2021 primarily due to higher account analysis fees. The Company's gross commercial and commercial real estate loan pipelines remained strong as of June 30, 2021. Before the impact of scheduled payments and prepayments, gross commercial and commercial real estate loan pipelines were estimated to be approximately $1.2 billion to $1.3 billion at June 30, 2021. When adjusted for the probability of closing, the pipelines were estimated to be approximately $700 million to $800 million at June 30, 2021.

Specialty Finance

Through its specialty finance unit, the Company offers financing of insurance premiums for businesses and individuals, equipment financing through structured loans and lease products to customers in a variety of industries, accounts receivable financing and value-added, out-sourced administrative services and other services. Originations within the insurance premium financing receivables portfolio were $3.4 billion during the second quarter of 2021 and average balances increased by $472.8 million as compared to the first quarter of 2021. The increase in average balances in the insurance premium finance receivables portfolios more than offset the related margin compression, attributed to lower market rates of interest, resulting in a $3.0 million increase in interest income. The Company's leasing business remained effectively unchanged from the first quarter of 2021 to the second quarter of 2021, with its portfolio of assets, including capital leases, loans and equipment on operating leases, at $2.2 billion at the end of the second quarter of 2021. Revenues from the Company's out-sourced administrative services business were $1.2 million in the second quarter of 2021, essentially unchanged from the first quarter of 2021.

Wealth Management

Through four separate subsidiaries within its wealth management unit, the Company offers a full range of wealth management services, including trust and investment services, tax-deferred like-kind exchange services, asset management, securities brokerage services and 401(k) and retirement plan services. Wealth management revenue totaled $30.7 million in the second quarter of 2021, an increase of $1.4 million compared to the first quarter of 2021. Increases in asset management fees were primarily due to favorable equity market performance during the second quarter of 2021. At June 30, 2021, the Company’s wealth management subsidiaries had approximately $34.2 billion of assets under administration, which included $4.7 billion of assets owned by the Company and its subsidiary banks, representing a $2.0 billion increase from the $32.2 billion of assets under administration at March 31, 2021.

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

(2)See "Supplemental Non-GAAP Financial Measures/Ratios" at Table 18 for additional information on this performance measure/ratio.

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

(4)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.

(5)Excludes mortgage loans held-for-sale.

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 website at www.wintrust.com by choosing “Financial Reports” under the “Investor Relations” heading, and then choosing “Financial Highlights.”

TABLE 8: 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 is as follows:

Static Shock Scenario	+200 <br>Basis <br>Points		+100<br> Basis<br> Points		-100 <br>Basis<br> Points
Jun 30, 2021	24.6	%	11.7	%	(6.9)	%

As noted in the table on the previous page, the majority of the Company’s portfolio is tied to LIBOR indices which, as shown in the table above, do not mirror the same changes as the Prime rate which has historically moved when the Federal Reserve raises or lowers interest rates.  Specifically, the Company has $9.4 billion of variable rate loans tied to one-month LIBOR and $6.4 billion of variable rate loans tied to twelve-month LIBOR. The above chart shows:

	Basis Point (bp) Change in

TABLE 18: SUPPLEMENTAL NON-GAAP 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), taxable-equivalent net interest margin (including its individual components), the taxable-equivalent efficiency ratio, tangible common equity ratio, tangible book value per common share, return on average tangible common equity and pre-tax income, excluding provision for credit losses. Management believes that these measures and ratios provide users of the Company’s financial information a more meaningful view of the performance of the Company's 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 basis. In this non-GAAP presentation, net interest income is adjusted to reflect tax-exempt interest income on an equivalent before-tax basis using tax rates effective as of the end of the period. This measure ensures comparability of net interest income arising from both taxable and tax-exempt sources. Net interest income on a fully taxable-equivalent 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 pre-tax income, excluding provision for credit losses, as a useful measurement of the Company's core net income.

Approximately 80% of the estimated increase is related to: ◦ Additions to existing reserves for unfunded lending-related commitments due to the consideration under CECL of expected utilization by the Company's borrowers over the life of such commitments. ◦ Establishment of reserves for acquired loans which previously considered credit discounts.

However, certain non- GAAP performance measures and ratios are used by management to evaluate and measure the Company’s performance. Management believes that these measures and ratios provide users of the Company’s financial information a more meaningful view of the performance of the Company's interest-earning assets and interest-bearing liabilities and of the Company’s operating efficiency.

23 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,” “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, such as the impacts of the COVID-19 pandemic, and which may include, but are not limited to, those listed below and the Risk Factors discussed under Item 1A of the Company’s 2020 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: • the severity, magnitude and duration of the COVID-19 pandemic, including the emergence of variant strains, and the direct and indirect impact of such pandemic, as well as responses to the pandemic by the government, businesses and consumers, on our operations and personnel, commercial activity and demand across our business and our customers’ businesses; • the disruption of global, national, state and local economies associated with the COVID-19 pandemic, which could affect the Company’s liquidity and capital positions, impair the ability of our borrowers to repay outstanding loans, impair collateral values and further increase our allowance for credit losses; • the impact of the COVID-19 pandemic on our financial results, including possible lost revenue and increased expenses (including the cost of capital), as well as possible goodwill impairment charges; • economic conditions that affect the economy, housing prices, the job market and other factors that may adversely affect the Company’s liquidity and the performance of its loan portfolios, particularly in the markets in which it operates; • negative effects suffered by us or our customers resulting from changes in U.S. trade policies; • the extent of defaults and losses on the Company’s loan portfolio, which may require further increases in its allowance for credit losses; • estimates of fair value of certain of the Company’s assets and liabilities, which could change in value significantly from period to period; • the financial success and economic viability of the borrowers of our commercial loans; • commercial real estate market conditions in the Chicago metropolitan area and southern Wisconsin; • the extent of commercial and consumer delinquencies and declines in real estate values, which may require further increases in the Company’s allowance for credit losses; • inaccurate assumptions in our analytical and forecasting models used to manage our loan portfolio; • changes in the level and volatility of interest rates, the capital markets and other market indices (including developments and volatility arising from or related to the COVID-19 pandemic) that may affect, among other things, the Company’s liquidity and the value of its assets and liabilities; • a prolonged period of near zero interest rates or potentially negative interest rates, either broadly or for some types of instruments, which may affect the Company’s net interest income and net interest margin, and which could materially adversely affect the Company’s profitability; • competitive pressures in the financial services business which may affect the pricing of the Company’s loan and deposit products as well as its services (including wealth management services), which may result in loss of market share and reduced income from deposits, loans, advisory fees and income from other products; • failure to identify and complete favorable acquisitions in the future or unexpected difficulties or developments related to the integration of the Company’s recent or future acquisitions; • unexpected difficulties and losses related to FDIC-assisted acquisitions; • harm to the Company’s reputation; • any negative perception of the Company’s financial strength; • ability of the Company to raise additional capital on acceptable terms when needed; • disruption in capital markets, which may lower fair values for the Company’s investment portfolio; Forward-Looking Statements
