WINTRUST FINANCIAL CORPORATION AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(1) Basis of Presentation

The interim consolidated financial statements of Wintrust Financial Corporation and its subsidiaries (collectively, “Wintrust” or the “Company”) presented herein are unaudited, but in the opinion of management, reflect all necessary adjustments of a normal or recurring nature for a fair presentation of results as of the dates and for the periods covered by the interim consolidated financial statements.

The accompanying interim consolidated financial statements are unaudited and do not include information or footnotes necessary for a complete presentation of financial condition, results of operations or cash flows in accordance with U.S. generally accepted accounting principles (“GAAP”). The interim unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (“2020 Form 10-K”). Operating results reported for the period are not necessarily indicative of the results which may be expected for the entire year. Reclassifications of certain prior period amounts have been made to conform to the current period presentation.

The preparation of the financial statements requires management to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities. Management believes that the estimates made are reasonable; however, changes in estimates may be required if economic or other conditions develop differently from management’s expectations. Certain policies and accounting principles inherently have a greater reliance on the use of estimates, assumptions and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Management views critical accounting policies to be those which are highly dependent on subjective or complex judgments, estimates and assumptions, and where changes in those estimates and assumptions could have a significant impact on the financial statements. Management currently views the determination of the allowance for credit losses, including the allowance for loan losses, the allowance for unfunded commitment losses and the allowance for held-to-maturity securities losses, estimations of fair value, the valuations required for impairment testing of goodwill, the valuation and accounting for derivative instruments and income taxes as the accounting areas that require the most subjective and complex judgments, and as such could be the most subject to revision as new information becomes available. Descriptions of the Company's significant accounting policies are included in Note 1 - “Summary of Significant Accounting Policies” of the 2020 Form 10-K.

(2) Recent Accounting Developments

Legislation and Regulations Issued as a Result of the COVID-19 Pandemic

On March 27, 2020, the President of the United States signed the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act" or the "Act"), which provides entities with optional temporary relief from certain accounting and financial reporting requirements under U.S. GAAP.

Section 4013 of the CARES Act allows financial institutions to suspend application of certain current troubled debt restructuring ("TDR") accounting guidance under Accounting Standards Codification (“ASC”) 310-40 for loan modifications related to the COVID-19 pandemic made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the COVID-19 national emergency, provided certain criteria are met. This relief can be applied to loan modifications for borrowers that were not more than 30 days past due as of December 31, 2019 and to loan modifications that defer or delay the payment of principal or interest, or change the interest rate on the loan. On December 27, 2020, the Consolidated Appropriations Act, 2021 (the "CAA"), which combined stimulus relief for the COVID-19 pandemic with an omnibus spending bill for the 2021 fiscal year, was signed by the President of the United States. The CAA included extension of TDR accounting relief provided under the CARES Act to January 1, 2022. The Company chose to apply this relief to eligible loan modifications.

The business tax provisions of the Act include temporary changes to income and non-income based tax laws, including immediate recovery of qualified improvement property costs and acceleration of Alternative Minimum Tax (AMT) credits. These provisions did not have a material impact on the Company's deferred taxes.

In April 2020, federal and state banking regulators issued the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus to provide separate relief, specifically indicating that if a modification is either short-term (e.g., six months) or mandated by a federal or state government in response to the COVID-19 pandemic, the borrower is not considered to be experiencing financial difficulty and thus does not represent a TDR under ASC 310-40. Additionally, in August 2020, regulators issued the Joint Statement on Additional Loan Accommodations

Related to the COVID-19 pandemic to provide prudent risk management and consumer protection principles for financial institutions to consider while working with borrowers as loans near the end of initial loan accommodation periods applicable during the COVID-19 pandemic. The Company continues to prudently work with borrowers negatively impacted by the COVID-19 pandemic while managing credit risks and recognizing appropriate allowance for credit losses on its loan portfolio.

Reference Rate Reform

In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848),” which provides temporary optional relief for contracts modified as a result of reference rate reform meeting certain modification criteria, generally allowing an entity to account for contract modifications occurring due to reference rate reform as an event that does not require contract remeasurement or reassessment of a previous accounting determination at the modification date. The guidance also includes temporary optional expedients intended to provide relief from various hedge effectiveness requirements for hedging relationships affected by reference rate reform, provided certain criteria are met, and allows a one-time election to sell or transfer to either available-for-sale or trading any held-to-maturity ("HTM") debt securities that refer to an interest rate affected by reference rate reform and were classified as HTM prior to January 1, 2020. Additionally, in January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (Topic 848): Scope,” which provided additional clarification that certain optional expedients and exceptions noted above apply to derivative instruments that use an interest rate for margining, discounting or contract price alignment that is modified as a result of reference rate reform. This guidance was effective upon issuance and can be applied prospectively, with certain exceptions, through December 31, 2022.

In November 2020, federal and state banking regulators issued the “Interagency Policy Statement on Reference Rates for Loans" to reiterate that a specific replacement rate for loans impacted by reference rate reform has not been endorsed and entities may utilize any replacement reference rate determined to be appropriate based on its funding model and customer needs. As discussed in the “Interagency Policy Statement on Reference Rates for Loans," fallback language should be included in lending contracts to provide for use of a robust fallback rate if the initial reference rate is discontinued. Additionally, federal banking regulators issued the "Interagency Statement on LIBOR Transition" acknowledging that the administrator of USD LIBOR benchmarks has announced it will consult on its intention to cease the publication of the one week and two month USD LIBOR settings immediately following the LIBOR publication on December 31, 2021, and the remaining USD LIBOR settings immediately following the LIBOR publication on June 30, 2023. On March 5, 2021, the administrator of USD LIBOR benchmarks confirmed these dates and will cease publication of USD LIBOR tenors accordingly. As discussed in the "Interagency Statement on LIBOR Transition," regulators encouraged banks to cease entering into new contracts that use USD LIBOR as a reference rate as soon as practicable and in any event by December 31, 2021, in order to facilitate an orderly, safe and sound LIBOR transition. The Company continues to monitor efforts and evaluate the impact of reference rate reform on its consolidated financial statements.

Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes," to simplify the accounting for income taxes by removing certain exceptions to the general principles of ASC 740, "Income Taxes". The guidance also improved consistent application by clarifying and amending existing guidance from ASC 740. The Company adopted ASU No. 2019-12 as of January 1, 2021. Adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

Investment Securities

In January 2020, the FASB issued ASU No. 2020-01, “Clarifying the Interactions Between Investments-Equity Securities (ASC Topic 321), Investments-Equity Method and Joint Ventures (ASC Topic 323), and Derivatives and Hedging (ASC Topic 815),” which amended ASC 323, Investments-Equity Method & Joint Ventures to clarify that an entity should consider observable transactions that require it to either apply or discontinue using the equity method of accounting for purposes of applying the measurement alternative in accordance with ASC 321, Investments-Equity Securities, immediately before applying or discontinuing the equity method under ASC 323.

The guidance also amended ASC 815, Derivatives & Hedging, to clarify that, when determining the accounting for certain nonderivative forward contracts and purchased options, an entity should not consider how to account for the resulting investments upon eventual settlement or exercise, and that an entity should evaluate the remaining characteristics in accordance with ASC 815 to determine the accounting for those forward contracts and purchased options.

The Company adopted ASU No. 2020-01 as of January 1, 2021 under a prospective approach. Adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

Codification Improvements

In October 2020, the FASB issued ASU No. 2020-08, “Codification Improvements to Subtopic 310-20, Receivables — Nonrefundable Fees and Other Costs,” clarifying that, for each reporting period, an entity should reevaluate whether a callable debt security with multiple call dates is within the scope of ASC 310-20, which was amended to require amortization of any premium to the next call date. The next call date was defined as the first date when a call option at a specified price becomes exercisable. The Company adopted ASU No. 2020-08 as of January 1, 2021 under a prospective approach. Adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

Additionally, the FASB issued ASU No. 2020-10, “Codification Improvements,” in October 2020 to improve the consistency of the Codification by adding or moving disclosure-specific guidance contained in the Other Presentation Matters section to the appropriate Disclosure Section for various Topics. The Company adopted ASU No. 2020-10 as of January 1, 2021 under a retrospective approach. Adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

SEC Amendments to Financial Disclosures about Acquired and Disposed Businesses

In May 2020, the SEC issued a final rule on “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” which provides for specific disclosure changes, including revising the investment and income significance tests, conforming the significance threshold and tests for a disposed business to those used for an acquired business, permitting abbreviated financial statements for certain acquisitions of a component of an entity, and reducing the maximum number of years for which financial statements are required for acquired businesses from three years to two years, among other amendments. This guidance was effective on January 1, 2021.

Debt

In August 2020, the FASB issued ASU No. 2020-06, “Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” which includes provisions for reducing the number of accounting models used in accounting for convertible debt instruments and convertible preferred stock, amending derivatives and earnings-per-share (EPS) guidance and expanding disclosures for convertible debt instruments and EPS. This guidance is effective for fiscal years beginning after December 15, 2021, including interim periods therein, and is to be applied under either a full or modified retrospective approach. Early adoption is permitted. The Company does not expect this guidance to have a material impact on the Company’s consolidated financial statements.

SEC Update of Statistical Disclosures for Bank and Savings and Loan Registrants

In September 2020, the SEC issued a final rule on the “Update of Statistical Disclosures for Bank and Savings and Loan Registrants,” which adopts rules to update statistical disclosure requirements for banking registrants. The amendments update and expand the disclosures that registrants are required to provide, codify certain Industry Guide 3 disclosure items and eliminate other Guide 3 disclosures that overlap with SEC rules, GAAP or IFRS standards. In addition, Guide 3 is being rescinded and replaced with a new subpart of Regulation S-K. The SEC ruling is applicable to fiscal years beginning after December 15, 2021 and early compliance is permitted. The Company does not expect this guidance to have a material impact on the Company’s consolidated financial statements.

(3) Cash and Cash Equivalents

For purposes of the Consolidated Statements of Cash Flows, the Company considers cash and cash equivalents to include cash on hand, cash items in the process of collection, non-interest bearing amounts due from correspondent banks, federal funds sold and securities purchased under resale agreements with original maturities of three months or less. These items are included within the Company’s Consolidated Statements of Condition as cash and due from banks, and federal funds sold and securities purchased under resale agreements.

to identify potential transactions that may indicate an observable price change in orderly transactions for the identical or a similar investment of the same issuer, requiring adjustment to its carrying amount. The Company recorded no upward and no downward adjustments related to such observable price changes for the three months ended March 31, 2021. The Company conducts a quarterly assessment of its equity securities without readily determinable fair values to determine whether impairment exists in such securities, considering, among other factors, the nature of the securities, financial condition of the issuer and expected future cash flows. During the three months ended March 31, 2021, the Company recorded $30,000 of impairment of equity securities without readily determinable fair values.

The following table presents the portion of the Company’s available-for-sale investment securities portfolios that have gross unrealized losses, reflecting the length of time that individual securities have been in a continuous unrealized loss position at March 31, 2021:

The Company conducts a regular assessment of its investment securities to determine whether securities are experiencing credit losses. Factors for consideration include the nature of the securities, credit ratings or financial condition of the issuer, the extent of the unrealized loss, expected cash flows, market conditions and the Company’s ability to hold the securities through the anticipated recovery period.

The Company does not consider available-for-sale securities with unrealized losses at March 31, 2021 to be experiencing credit losses and recognized no resulting allowance for credit losses for such individually assessed credit losses. The Company does not intend to sell these investments and it is more likely than not that the Company will not be required to sell these investments before recovery of the amortized cost bases, which may be the maturity dates of the securities. The unrealized losses within each category have occurred as a result of changes in interest rates, market spreads and market conditions subsequent to purchase. Available-for-sale securities with continuous unrealized losses existing for more than twelve months were primarily corporate notes.

See Note 6—Allowance for Credit Losses for further discussion regarding any credit losses associated with held-to-maturity securities at March 31, 2021.

The Company’s loan portfolio is generally comprised of loans to consumers and small to medium-sized businesses, which, for the commercial and commercial real estate portfolios, are located primarily within the geographic market areas that the banks serve. Various niche lending businesses, including lease finance and franchise lending, operate on a national level. Additionally, to provide short-term relief due to macroeconomic deterioration from the COVID-19 pandemic to small businesses within such market areas, the Company originated loans through the Paycheck Protection Program ("PPP"), an expansion of guaranteed lending under Section 7(a) of the Small Business Act within the CARES Act. As of March 31, 2021, the Company's commercial portfolio included approximately $3.3 billion of such PPP loans. The premium finance receivables portfolios are made to customers throughout the United States and Canada. The Company strives to maintain a loan portfolio that is diverse in terms of loan type, industry, borrower and geographic concentrations. Such diversification reduces the exposure to economic downturns that may occur in different segments of the economy or in different industries.

Certain premium finance receivables are recorded net of unearned income. The unearned income portions of such premium finance receivables were $114.4 million at March 31, 2021, $113.1 million at December 31, 2020 and $115.2 million at March 31, 2020.

Total loans, excluding PCD loans, include net deferred loan fees and costs and fair value purchase accounting adjustments totaling $(32.2) million at March 31, 2021, $(3.2) million at December 31, 2020 and $11.1 million at March 31, 2020. Net deferred fees as of March 31, 2021 includes $64.6 million of net deferred fees paid by the Small Business Administration ("SBA") for loans originated under the PPP. As PPP loans share similar characteristics (loan terms), and prepayments are considered probable and can reasonably be estimated due to terms of the program, the Company considers estimated future principal prepayments in recognizing such deferred fees for determining a constant effective yield on the portfolio of loans.

It is the policy of the Company to review each prospective credit in order to determine the appropriateness and, when required, the adequacy of security or collateral necessary to obtain when making a loan. The type of collateral, when required, will vary from liquid assets to real estate. The Company seeks to ensure access to collateral, in the event of default, through adherence to state lending laws and the Company’s credit monitoring procedures.

(6) Allowance for Credit Losses

In accordance with ASC 326, the Company is required to measure the allowance for credit losses of financial assets with similar risk characteristics on a collective or pooled basis. In considering the segmentation of financial assets measured at amortized cost into pools, the Company considered various risk characteristics in its analysis. Generally, the segmentation utilized represents the level at which the Company develops and documents its systematic methodology to determine the allowance for credit losses for the financial asset held at amortized cost, specifically the Company's loan portfolio and debt securities classified as held-to-maturity. Below is a summary of the Company's loan portfolio segments and major debt security types:

Commercial loans, including PPP loans: The Company makes commercial loans for many purposes, including working capital lines and leasing arrangements, that are generally renewable annually and supported by business assets, personal guarantees and additional collateral. Underlying collateral includes receivables, inventory, enterprise value and the assets of the business. Commercial business lending is generally considered to involve a slightly higher degree of risk than traditional consumer bank lending. This portfolio includes a range of industries, including manufacturing, restaurants, franchise, professional services, equipment finance and leasing, mortgage warehouse lending and industrial.

The Company also originates loans through the PPP. Administered by the SBA, the PPP provides short-term relief primarily related to the disruption from COVID-19 to companies and non-profits that meet the SBA’s definition of an eligible small business. Under the program, the SBA will forgive all or a portion of the loan if, during a certain period, loans are used for qualifying expenses. If all or a portion of the loan is not forgiven, the borrower is responsible for repayment. PPP loans are fully guaranteed by the SBA, including any portion not forgiven. The SBA guarantee exists at the inception of the loan and throughout its life and is not separated from the loan if the loan is subsequently sold or transferred. As it is not considered a freestanding contract, the Company considers the impact of the SBA guarantee when measuring the allowance for credit losses.

Commercial real estate loans, including construction and development, and non-construction: The Company's commercial real estate loans are generally secured by a first mortgage lien and assignment of rents on the underlying property. Since most of the Company's bank branches are located in the Chicago metropolitan area and southern Wisconsin, a significant portion of the Company's commercial real estate loan portfolio is located in this region. As the risks and circumstances of such loans in construction phase vary from that of non-construction commercial real estate loans, the Company assessed the allowance for credit losses separately for these two segments.

Home equity loans: The Company's home equity loans and lines of credit are primarily originated by each of the bank subsidiaries in their local markets where there is a strong understanding of the underlying real estate value. The Company's banks monitor and manage these loans, and conduct an automated review of all home equity loans and lines of credit at least twice per year. The banks subsidiaries use this information to manage loans that may be higher risk and to determine whether to obtain additional credit information or updated property valuations. In a limited number of cases, the Company may issue home equity credit together with first mortgage financing, and requests for such financing are evaluated on a combined basis.

Residential real estate loans: The Company's residential real estate portfolio includes one- to four-family fixed and adjustable rate mortgages with repricing terms generally from one to three years, construction loans to individuals and bridge financing loans for qualifying customers. The Company's residential mortgages relate to properties located principally in the Chicago metropolitan area and southern Wisconsin or vacation homes owned by local residents. Due to interest rate risk considerations, the Company generally sells in the secondary market loans originated with long-term fixed rates, however, certain of these loans may be retained within the banks’ own portfolios where they are non-agency conforming, or where the terms of the loans make them favorable to retain. The Company believes that since this loan portfolio consists primarily of locally originated loans, and since the majority of the borrowers are longer-term customers with lower LTV ratios, the Company faces a relatively low risk of borrower default and delinquency. It is not the Company's current practice to underwrite, and there are no plans to underwrite subprime, Alt A, no or little documentation loans, or option ARM loans.

Premium finance receivables: The Company makes loans to businesses to finance the insurance premiums they pay on their commercial insurance policies. The loans are indirectly originated by working through independent medium and large insurance agents and brokers located throughout the United States and Canada. The insurance premiums financed are primarily for commercial customers’ purchases of liability, property and casualty and other commercial insurance. This lending involves relatively rapid turnover of the loan portfolio and high volume of loan originations. The Company performs ongoing credit and other reviews of the agents and brokers to mitigate against the risk of fraud.

The Company also originates life insurance premium finance receivables. These loans are originated directly with the borrowers with assistance from life insurance carriers, independent insurance agents, financial advisors and legal counsel. The life

insurance policy is the primary form of collateral. In addition, these loans often are secured with a letter of credit, marketable securities or certificates of deposit. In some cases, the Company may make a loan that has a partially unsecured position.

Consumer and other loans: Included in the consumer and other loan category is a wide variety of personal and consumer loans to individuals. The Company originates consumer loans in order to provide a wider range of financial services to their customers. Consumer loans generally have shorter terms and higher interest rates than mortgage loans but generally involve more credit risk than mortgage loans due to the type and nature of the collateral.

U.S. government agency securities: This security type includes debt obligations of certain government-sponsored entities of the U.S. government such as the Federal Home Loan Bank, Federal Agricultural Mortgage Corporation, Federal Farm Credit Banks Funding Corporation and Fannie Mae. Such securities often contain an explicit or implicit guarantee of the U.S. government.

Municipal securities: The Company's municipal securities portfolio include bond issues for various municipal government entities located throughout the United States, including the Chicago metropolitan area and southern Wisconsin, some of which are privately placed and non-rated. Though the risk of loss is typically low, including within the Company, default history exists on municipal securities within the United States.

Mortgage-backed securities: This security type includes debt obligations supported by pools of individual mortgage loans and issued by certain government-sponsored entities of the U.S. government such as Freddie Mac and Fannie Mae. Such securities are considered to contain an implicit guarantee of the U.S. government.

Corporate notes: The Company's corporate notes portfolio includes bond issues for various public companies representing a diversified population of industries. The risk of loss in this portfolio is considered low based on the characteristics of the investments, including the Company’s own past history with similar investments.

In accordance with ASC 326, the Company elected to not measure an allowance for credit losses on accrued interest as such accrued interest is written off in a timely manner when deemed uncollectible. Any such write-off of accrued interest will reverse previously recognized interest income. In addition, the Company elected to not include accrued interest within presentation and disclosures of the carrying amount of financial assets held at amortized cost. This election is applicable to the various disclosures included within the Company's financial statements. Accrued interest related to financial assets held at amortized cost is included within accrued interest receivable and other assets within the Company's Consolidated Statements of Condition and totaled $128.8 million at March 31, 2021, $121.9 million at December 31, 2020 and $116.4 million at March 31, 2020.

Credit Quality Indicators

Credit quality indicators, specifically the Company's internal risk rating systems, reflect how the Company monitors credit losses and represents factors used by the Company when measuring the allowance for credit losses. The following discusses the Company's credit quality indicators by financial asset.

Loan portfolios

The Company's ability to manage credit risk depends in large part on our ability to properly identify and manage problem loans. To do so, the Company operates a credit risk rating system under which credit management personnel assign a credit risk rating (1 to 10 rating) to each loan at the time of origination and review loans on a regular basis. These credit risk ratings are also an important aspect of the Company's allowance for credit losses measurement methodology. The credit risk rating structure and classifications are shown below:

Pass (risk rating 1 to 5): Based on various factors (liquidity, leverage, etc.), the Company believes asset quality is acceptable and is deemed to not require additional monitoring by the Company.

Special mention (risk rating 6): Assets in this category are currently protected, potentially weak, but not to the point of substandard classification. Loss potential is moderate if corrective action is not taken.

Substandard accrual (risk rating 7): Assets in this category have well defined weaknesses that jeopardize the liquidation of the debt. Loss potential is distinct but with no discernible impairment.

Substandard nonaccrual/doubtful (risk rating 8 and 9): Assets have all the weaknesses in those classified “substandard accrual” with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of current existing facts, conditions, and values, improbable.

Table of Contents

Loss/fully charged-off (risk rating 10): Assets in this category are considered fully uncollectible. As such, these assets have no carrying balance on the Company's Consolidated Statements of Condition.

Each loan officer is responsible for monitoring his or her loan portfolio, recommending a credit risk rating for each loan in his or her portfolio and ensuring the credit risk ratings are appropriate. These credit risk ratings are then ratified by the bank’s chief credit officer and/or concurrence credit officer. Credit risk ratings are determined by evaluating a number of factors including: a borrower’s financial strength, cash flow coverage, collateral protection and guarantees.

The Company’s Problem Loan Reporting system includes all loans with credit risk ratings of 6 through 9. This system is designed to provide an on-going detailed tracking mechanism for each problem loan. Once management determines that a loan has deteriorated to a point where it has a credit risk rating of 6 or worse, the Company’s Managed Asset Division performs an overall credit and collateral review. As part of this review, all underlying collateral is identified and the valuation methodology is analyzed and tracked. As a result of this initial review by the Company’s Managed Asset Division, the credit risk rating is reviewed and a portion of the outstanding loan balance may be deemed uncollectible and, as a result, no longer share similar risk characteristics as its related pool. If that is the case, the individual loan is considered collateral dependent and individually assessed for an allowance for credit loss. The Company’s individual assessment utilizes an independent re-appraisal of the collateral (unless such a third-party evaluation is not possible due to the unique nature of the collateral, such as a closely-held business or thinly traded securities). In the case of commercial real estate collateral, an independent third party appraisal is ordered by the Company’s Real Estate Services Group to determine if there has been any change in the underlying collateral value. These independent appraisals are reviewed by the Real Estate Services Group and sometimes by independent third party valuation experts and may be adjusted depending upon market conditions.

Through the credit risk rating process, loans are reviewed to determine if they are performing in accordance with the original contractual terms. If the borrower has failed to comply with the original contractual terms, further action may be required by the Company, including a downgrade in the credit risk rating, movement to non-accrual status or a charge-off. If the Company determines that a loan amount or portion thereof is uncollectible, the loan’s credit risk rating is immediately downgraded to an 8 or 9 and the uncollectible amount is charged-off. Any loan that has a partial charge-off continues to be assigned a credit risk rating of an 8 or 9 for the duration of time that a balance remains outstanding. The Company undertakes a thorough and ongoing analysis to determine if additional impairment and/or charge-offs are appropriate and to begin a workout plan for the credit to minimize actual losses. In determining the appropriate charge-off for collateral-dependent loans, the Company considers the results of appraisals for the associated collateral.

(1)Includes $164.7 million of loans with COVID-19 related modifications that migrated from pass as of March 1, 2020 to special mention or substandard accrual as of March 31, 2021. These loans were further qualitatively evaluated as a part of the measurement of the allowance for credit losses as of March 31, 2021.

Held-to-maturity debt securities

The Company conducts an assessment of its investment securities, including those classified as held-to-maturity, at the time of purchase and on at least an annual basis to ensure such investment securities remain within appropriate levels of risk and continue to perform satisfactorily in fulfilling its obligations. The Company considers, among other factors, the nature of the securities and credit ratings or financial condition of the issuer. If available, the Company obtains a credit rating for issuers from a Nationally Recognized Statistical Rating Organization (“NRSRO”) for consideration. If no such rating is available for an issuer, the Company performs an internal rating based on the scale utilized within the loan portfolio as discussed above. For purposes of the table below, the Company has converted any issuer rating from an NRSRO into the Company’s internal ratings based on Investment Policy and review by the Company’s management.

Measurement of Allowance for Credit Losses

The Company's allowance for credit losses consists of the allowance for loan losses, the allowance for unfunded commitment losses and the allowance for held-to-maturity debt security losses. In accordance with ASC 326, the Company measures the allowance for credit losses at the time of origination or purchase of a financial asset, representing an estimate of lifetime expected credit losses on the related asset. When developing its estimate, the Company considers available information relevant to assessing the collectability of cash flows, from both internal and external sources. Historical credit loss experience is one input in the estimation process as well as inputs relevant to current conditions and reasonable and supportable forecasts. In considering past events, the Company considers the relevance, or lack thereof, of historical information due to changes in such things as financial asset underwriting or collection practices, and changes in portfolio mix due to changing business plans and strategies. In considering current conditions and forecasts, the Company considers both the current economic environment and the forecasted direction of the economic environment with emphasis on those factors deemed relevant to or driving changes in expected credit losses. As significant judgment is required, the review of the appropriateness of the allowance for credit losses is performed quarterly by various committees with participation by the Company's executive management.

The allowance for credit losses is measured on a collective or pooled basis when similar risk characteristics exist, based upon the segmentation discussed above. The Company utilizes modeling methodologies that estimate lifetime credit loss rates on each pool, including methodologies estimating the probability of default and loss given default on specific segments. Historical credit loss history is adjusted for reasonable and supportable forecasts developed by the Company on a quantitative or qualitative basis and incorporates third party economic forecasts. Reasonable and supportable forecasts consider the macroeconomic factors that are most relevant to evaluating and predicting expected credit losses in the Company's financial assets. Currently, the Company utilizes an eight quarter forecast period using a single macroeconomic scenario provided by a

third-party and reviewed within the Company's governance structure. For periods beyond the ability to develop reasonable and supportable forecasts, the Company reverts to historical loss rates at an input level, straight-line over a four quarter reversion period. Expected credit losses are measured over the contractual term of the financial asset with consideration of expected prepayments. Expected extensions, renewals or modifications of the financial asset are only considered when either 1) the expected extension, renewal or modification is contained within the existing agreement and is not unconditionally cancelable, or 2) the expected extension, renewal or modification is reasonably expected to result in a TDR. The methodologies discussed above are applied to both current asset balances on the Company's Consolidated Statements of Condition and off-balance sheet commitments (i.e. unfunded lending-related commitments).

Assets that do not share similar risk characteristics with a pool are assessed for the allowance for credit losses on an individual basis. These typically include assets experiencing financial difficulties, including assets rated as substandard nonaccrual and doubtful as well as assets currently classified or expected to be classified as TDRs. If foreclosure is probable or the asset is considered collateral-dependent, expected credit losses are measured based upon the fair value of the underlying collateral adjusted for selling costs, if appropriate. Underlying collateral across the Company's segments consist primarily of real estate, land and construction assets as well as general business assets of the borrower. As of March 31, 2021, substandard nonaccrual loans totaling $56.8 million in carrying balance had no related allowance for credit losses. For certain accruing current and expected TDRs, expected credit losses are measured based upon the present value of future cash flows of the modified asset terms compared to the amortized cost of the asset. Considering accounting relief provided under Section 4013 of the CARES Act, loans identified as being reasonably expected to be modified into TDRs in the future totaled $198,000 as of March 31, 2021.

The Company does not measure an allowance for credit losses on accrued interest receivable balances because these balances are written off in a timely manner as a reduction to interest income when assets are placed on nonaccrual status.

At January 1, 2020, the Company adopted ASU 2016-13, which replaced the previous incurred loss methodology for measuring the allowance for credit losses with a lifetime expected loss methodology. At adoption, the allowance for credit losses related to loans and lending agreements increased approximately $47.3 million, including an increase of approximately $33.2 million recorded to the allowance for unfunded commitment losses within accrued interest and other liabilities on the Company's Consolidated Statements of Condition, with an offsetting amount recorded directly to retained earnings, net of taxes. The remaining $14.2 million cumulative effect adjustment was recorded to the allowance for loan losses, presented separately on the Company's Consolidated Statements of Condition. Of the amount recorded to the allowance for loan losses, $11.0 million related to PCD loans with such offsetting amount added directly to the carrying balance of the loans and the remaining $3.2 million not related to PCD loans recorded directly to retained earnings, net of taxes, on the Company's Consolidated Statements of Condition.

For the three months ended March 31, 2021 and 2020, the Company recognized approximately $(45.4) million and $53.0 million of provision for credit losses, respectively, related to loans and lending agreements. The decreased provision was primarily the result of improvements in the forecasted macroeconomic conditions created by the COVID-19 pandemic, and the resulting impact on the Company's macroeconomic forecasts of key model inputs (most notably, Commercial Real Estate Price Index and Baa corporate credit spreads) as well as improvements in characteristics of the Company's loan portfolios. While uncertainties remain regarding expected economic recovery, macroeconomic forecasts as of March 31, 2021 assume that the impact of those uncertainties is less severe compared to that assumed at December 31, 2020. Other key drivers of provision for credit losses in these portfolios include, but are not limited to, net new loan growth and loan risk rating migration. Net charge-offs in the three month period ending March 31, 2021, totaled $13.3 million.

Held-to-maturity debt securities

At January 1, 2020, the Company established an allowance for credit losses on its held-to-maturity debt securities totaling approximately $74,000, which is presented as a reduction to the amortized cost basis of held-to-maturity securities on the Company's Consolidated Statements of Condition. Such adjustment was recorded directly to the Company's retained earnings, net of taxes. For the three month period ended March 31, 2021, the Company recognized approximately $39,000 of provision for credit losses related to held-to-maturity securities.

TDRs

At March 31, 2021, the Company had $56.6 million in loans modified in TDRs. The $56.6 million in TDRs represents 273 credits in which economic concessions were granted to certain borrowers to better align the terms of their loans with their current ability to pay.

The Company’s approach to restructuring loans is built on its credit risk rating system, which requires credit management personnel to assign a credit risk rating to each loan. In each case, the loan officer is responsible for recommending a credit risk rating for each loan and ensuring the credit risk ratings are appropriate. These credit risk ratings are then reviewed and approved by the bank’s chief credit officer and/or concurrence credit officer. Credit risk ratings are determined by evaluating a number of factors, including a borrower’s financial strength, cash flow coverage, collateral protection and guarantees. The Company’s

21

Table of Contents

credit risk rating scale is one through ten with higher scores indicating higher risk. In the case of loans rated six or worse following modification, the Company’s Managed Assets Division evaluates the loan and the credit risk rating and determines that the loan has been restructured to be reasonably assured of repayment and of performance according to the modified terms and is supported by a current, well-documented credit assessment of the borrower’s financial condition and prospects for repayment under the revised terms.

A modification of a loan with an existing credit risk rating of 6 or worse or a modification of any other credit, which will result in a restructured credit risk rating of 6 or worse must be reviewed for possible TDR classification. In that event, the Company’s Managed Assets Division conducts an overall credit and collateral review. A modification of a loan is considered to be a TDR if both (1) the borrower is experiencing financial difficulty and (2) for economic or legal reasons, the bank grants a concession to a borrower that it would not otherwise consider. The modification of a loan where the credit risk rating is 5 or better after such modification is not considered to be a TDR. Based on the Company’s credit risk rating system, it considers that borrowers whose credit risk rating is 5 or better are not experiencing financial difficulties and therefore, are not considered TDRs.

All credits determined to be a TDR will continue to be classified as a TDR in all subsequent periods, unless the borrower has been in compliance with the loan’s modified terms for a period of six months (including over a calendar year-end) and the current interest rate represents a market rate at the time of restructuring. The Managed Assets Division, in consultation with the respective loan officer, determines whether the modified interest rate represented a current market rate at the time of restructuring. Using knowledge of current market conditions and rates, competitive pricing on recent loan originations, and an assessment of various characteristics of the modified loan (including collateral position and payment history), an appropriate market rate for a new borrower with similar risk is determined. If the modified interest rate meets or exceeds this market rate for a new borrower with similar risk, the modified interest rate represents a market rate at the time of restructuring. Additionally, before removing a loan from TDR classification, a review of the current or previously measured impairment on the loan and any concerns related to future performance by the borrower is conducted. If concerns exist about the future ability of the borrower to meet its obligations under the loans based on a credit review by the Managed Assets Division, the TDR classification is not removed from the loan.

TDRs are individually assessed at the time of the modification and on a quarterly basis to measure an allowance for credit loss. The carrying amount of the loan is compared to the expected payments to be received, discounted at the loan's original rate, or for collateral dependent loans, to the fair value of the collateral. Any shortfall is recorded as a reserve. Each TDR was individually assessed at March 31, 2021 and approximately $2.5 million of reserve was present and appropriately reserved for through the Company’s reserving methodology in the Company’s allowance for credit losses.

TDRs may arise when, due to financial difficulties experienced by the borrower, the Company obtains through physical possession one or more collateral assets in satisfaction of all or part of an existing credit. Once possession is obtained, the Company reclassifies the appropriate portion of the remaining balance of the credit from loans to OREO, which is included within other assets in the Consolidated Statements of Condition. For any residential real estate property collateralizing a consumer mortgage loan, the Company is considered to possess the related collateral only if legal title is obtained upon completion of foreclosure, or the borrower conveys all interest in the residential real estate property to the Company through completion of a deed in lieu of foreclosure or similar legal agreement. At March 31, 2021, the Company had $4.0 million of foreclosed residential real estate properties included within OREO. Furthermore, the recorded investment in residential mortgage loans secured by residential real estate properties for which foreclosure proceedings are in process totaled $13.8 million and $10.6 million at March 31, 2021 and 2020, respectively.

The tables below present a summary of the post-modification balance of loans restructured during the three months ended March 31, 2021 and 2020, respectively, which represent TDRs:

During the three months ended March 31, 2021, 20 loans totaling $2.1 million were determined to be TDRs, compared to 38 loans totaling $23.8 million during the three months ended March 31, 2020. Of these loans extended at below market terms, the weighted average extension had a term of approximately 110 months during the quarter ended March 31, 2021 compared to eight months for the quarter ended March 31, 2020. Further, the weighted average decrease in the stated interest rate for loans with a reduction of interest rate during the period was approximately 127 basis points and 173 basis points during the three months ended March 31, 2021 and 2020, respectively. Interest-only payment terms were approximately six months and 21 months during the three months ended March 31, 2021 and 2020, respectively. Additionally, no principal balances were forgiven during the quarter ended March 31, 2021 and $453,000 of principal balances were forgiven in the quarter ended March 31, 2020.

Table of Contents

The Company assesses each reporting unit’s goodwill for impairment on at least an annual basis and considers potential indicators of impairment at each reporting date between annual goodwill impairment tests. At October 1, 2020, the Company utilized a quantitative approach for its annual goodwill impairment tests of the banking, specialty finance and wealth management reporting units and determined that no impairment existed at that time.

At each reporting date between annual goodwill impairment tests, the Company considers potential indicators of impairment. Given the current economic uncertainty and volatility surrounding COVID-19, the Company assessed whether such events and circumstances resulted in it being more likely than not that the fair value of any reporting unit was less than its carrying value. Impairment indicators considered include the condition of the economy and banking industry; government intervention and regulatory updates; the impact of recent events to financial performance and cost factors of the reporting units; performance of the Company’s stock and other relevant events. The Company further considered the amount by which fair value exceeded book value for each reporting unit in its most recent quantitative analysis and sensitivities performed.

At the conclusion of this assessment of all reporting units, the Company determined that as of March 31, 2021, it was more likely than not that the fair value of all reporting units exceeded the respective carrying value of such reporting unit.

The customer list and other intangibles recognized in connection with prior acquisitions within the wealth management segment are being amortized over a period of up to ten years on a straight-line basis. Indefinite-lived intangible assets consist of certain trade and domain names recognized in connection with the acquisition of Veterans First Mortgage in 2018. As indefinite-lived intangible assets are not amortized, the Company assesses impairment on at least an annual basis.

Total amortization expense associated with finite-lived intangibles totaled approximately $2.0 million and $2.9 million for the three months ended March 31, 2021 and 2020, respectively.

(8) Mortgage Servicing Rights (“MSRs”)

Fair value at end of the period	$	124,316	$	73,504
Unpaid principal balance of mortgage loans serviced for others	$	11,530,676	$	8,314,634

The Company recognizes MSR assets upon the sale of residential real estate loans to external third parties when it retains the obligation to service the loans and the servicing fee is more than adequate compensation. The initial recognition of MSR assets from loans sold with servicing retained and subsequent changes in fair value of all MSRs are recognized in mortgage banking revenue. MSRs are subject to changes in value from actual and expected prepayment of the underlying loans.

The estimation of fair value related to MSRs is partly impacted by the Company exercising its EBO on eligible loans previously sold to the Government National Mortgage Association (“GNMA”). Under such optional repurchase program, financial institutions acting as servicers are allowed to buy back from the securitized loan pool individual delinquent mortgage loans meeting certain criteria for which the institution was the original transferor of such loans. At the option of the servicer and without prior authorization from GNMA, the servicer may repurchase such delinquent loans for an amount equal to the remaining principal balance of the loan. At the time of such repurchase, any MSR value related to such loans is derecognized.

Starting in 2019, the Company periodically purchased options for the right to purchase securities not currently held within the banks’ investment portfolios and entered into interest rate swaps in which the Company elected to not designate such derivatives as hedging instruments. These option and swap transactions were designed primarily to economically hedge a portion of the fair value adjustments related to MSRs. During the second quarter of 2020, the Company terminated these interest rate swaps. There were no such options or interest rate swaps outstanding as of March 31, 2021. For more information regarding these hedges, see Note 14 - Derivative Financial Instruments in Item 1 of this report.

The MSR asset fair value is determined by using a discounted cash flow model that incorporates the objective characteristics of the portfolio as well as subjective valuation parameters that purchasers of servicing would apply to such portfolios sold into the secondary market. The subjective factors include loan prepayment speeds, discount rates, servicing costs and other economic factors. The Company uses a third party to assist in the valuation of MSRs.

FHLB Advances

FHLB advances consist of obligations of the banks and are collateralized by qualifying commercial and residential real estate and home equity loans and certain securities. FHLB advances are stated at par value of the debt adjusted for unamortized prepayment fees paid at the time of prior restructurings of FHLB advances, unamortized fair value adjustments recorded in connection with advances acquired through acquisitions and debt issuance costs.

Notes Payable

On September 18, 2018, the Company established a $150.0 million term facility ("Term Facility"), which is part of a $200.0 million loan agreement ("Credit Agreement") with unaffiliated banks. The Credit Agreement consists of the Term Facility with

26

Table of Contents

an original outstanding balance of $150.0 million and a $50.0 million revolving credit facility ("Revolving Credit Facility"). At March 31, 2021, the Company had a notes payable balance of $96.4 million under the Term Facility. The Term Facility is stated at par of the current outstanding balance of the debt adjusted for unamortized costs paid by the Company in relation to the debt issuance. The Company was contractually required to borrow the entire amount of the Term Facility on September 18, 2018 and all such borrowings must be repaid by September 18, 2023. Beginning December 31, 2018, the Company is required to make quarterly payments of principal plus interest on the Term Facility. At March 31, 2021, the Company had no outstanding balance under the Revolving Credit Facility. Unamortized costs paid by the Company in relation to the issuance of the Revolving Credit Facility are classified in other assets on the Consolidated Statements of Condition.

An amendment to the Credit Agreement was executed on and effective as of September 15, 2020. The amendment provided for, among other things, extension of the maturity date under the Revolving Credit Facility to September 14, 2021, revision of certain financial covenants; and the addition of a mechanism to replace LIBOR with an alternate benchmark rate.

Borrowings under the amended Credit Agreement that are considered “Base Rate Loans” bear interest at a rate equal to the sum of (1) 60 basis points (in the case of a borrowing under the Revolving Credit Facility) or 75 basis points (in the case of a borrowing under the Term Facility) plus (2) the highest of (a) the federal funds rate plus 50 basis points, (b) the lender's prime rate, or (c) the Eurodollar Rate (as defined below) that would be applicable for an interest period of one month plus 100 basis points. Borrowings under the agreement that are considered “Eurodollar Rate Loans” bear interest at a rate equal to the sum of (1) 135 basis points (in the case of a borrowing under the Revolving Credit Facility) or 125 basis points (in the case of a borrowing under the Term Facility) plus (2) the LIBOR rate for the applicable period, as adjusted for statutory reserve requirements for eurocurrency liabilities (the “Eurodollar Rate”). A commitment fee is payable quarterly equal to 0.30% of the actual daily amount by which the lenders' commitment under the Revolving Credit Facility exceeded the amount outstanding under such facility.

Borrowings under the amended Credit Agreement are secured by pledges of and first priority perfected security interests in the Company's equity interest in its bank subsidiaries and contain several restrictive covenants, including the maintenance of various capital adequacy levels, asset quality and profitability ratios, and certain restrictions on dividends and other indebtedness. In September 2020, the required levels to maintain for certain restrictive covenants within the Credit Agreement were amended. At March 31, 2021, the Company was in compliance with all such covenants. The Revolving Credit Facility and the Term Facility are available to be utilized, as needed, to provide capital to fund continued growth at the Company’s banks and to serve as an interim source of funds for acquisitions, common stock repurchases or other general corporate purposes.

Short-term Borrowings

Short-term borrowings include securities sold under repurchase agreements and federal funds purchased. These borrowings totaled $12.4 million at March 31, 2021 compared to $11.4 million at December 31, 2020 and $12.1 million at March 31, 2020. At March 31, 2021, December 31, 2020 and March 31, 2020, securities sold under repurchase agreements represent $12.4 million, $11.4 million and $12.1 million, respectively, of customer sweep accounts in connection with master repurchase agreements at the banks. The Company records securities sold under repurchase agreements at their gross value and does not offset positions on the Consolidated Statements of Condition. As of March 31, 2021, the Company had pledged securities related to its customer balances in sweep accounts of $20.6 million. Securities pledged for customer balances in sweep accounts and short-term borrowings from brokers are maintained under the Company’s control and consist of mortgage-backed securities. These securities are included in the available-for-sale portfolio as reflected on the Company’s Consolidated Statements of Condition.

The following is a summary of these securities pledged as of March 31, 2021 disaggregated by investment category and maturity of the related customer sweep account, and reconciled to the outstanding balance of securities sold under repurchase agreements:

Secured Borrowings

Secured borrowings at March 31, 2021 primarily represents transactions to sell an undivided co-ownership interest in all receivables owed to the Company's subsidiary, First Insurance Funding of Canada ("FIFC Canada"). In December 2014, FIFC Canada sold such interest to an unrelated third party in exchange for a cash payment of approximately C$150 million pursuant to a receivables purchase agreement (“Receivables Purchase Agreement”). The Receivables Purchase Agreement was amended in December 2015, effectively extending the maturity date from December 15, 2015 to December 15, 2017. Additionally, at that time, the unrelated third party paid an additional C$10 million, which increased the total payments to C$160 million. The Receivables Purchase Agreement was again amended in December 2017, effectively extending the maturity date from December 15, 2017 to December 16, 2019. Additionally, in December 2017, the unrelated third party paid an additional C$10 million, which increased the total payments to C$170 million. In June 2018, the unrelated third party paid an additional C$20 million, which increased the total payments to C$190 million. The Receivables Purchase Agreement was again amended in February 2019, effectively extending the maturity date from December 16, 2019 to December 15, 2020. Additionally, in February 2019, the unrelated third party paid an additional C$20 million, which increased the total payments to C$210 million. In May 2019, the unrelated third party paid an additional C$70 million, which increased the total payments to C$280 million. In January 2020, the unrelated third party paid an additional C$40 million, which increased the total payments to C$320 million, and the Receivables Purchase Agreement was amended to effectively extend the maturity date from December 15, 2020 to December 15, 2021. In May 2020, the unrelated third party paid an additional C$100 million, which increased the total payments to C$420 million. In January 2021, the Receivables Purchase Agreement was amended to effectively extend the maturity date from December 15, 2021 to December 15, 2022. These transactions were not considered sales of receivables and, as such, related proceeds received are reflected on the Company’s Consolidated Statements of Condition as a secured borrowing owed to the unrelated third party, net of unamortized debt issuance costs, and translated to the Company’s reporting currency as of the respective date. At March 31, 2021, the translated balance of the secured borrowing totaled $334.1 million compared to $329.9 million at December 31, 2020 and $227.4 million at March 31, 2020. Additionally, the interest rate under the Receivables Purchase Agreement at March 31, 2021 was 1.1015%. The remaining $9.4 million within secured borrowings at March 31, 2021 represents other sold interests in certain loans by the Company that were not considered sales and, as such, related proceeds received are reflected on the Company’s Consolidated Statements of Condition as a secured borrowing owed to the various unrelated third parties.

Subordinated Notes

At March 31, 2021, the Company had outstanding subordinated notes totaling $436.6 million compared to $436.5 million and $436.2 million outstanding at December 31, 2020 and March 31, 2020, respectively.

(11) Junior Subordinated Debentures

As of March 31, 2021, the Company owned 100% of the common securities of eleven trusts, Wintrust Capital Trust III, Wintrust Statutory Trust IV, Wintrust Statutory Trust V, Wintrust Capital Trust VII, Wintrust Capital Trust VIII, Wintrust Capital Trust IX, Northview Capital Trust I, Town Bankshares Capital Trust I, First Northwest Capital Trust I, Suburban Illinois Capital Trust II, and Community Financial Shares Statutory Trust II (the “Trusts”) set up to provide long-term financing. The Northview, Town, First Northwest, Suburban, and Community Financial Shares capital trusts were acquired as part of the acquisitions of Northview Financial Corporation, Town Bankshares, Ltd., First Northwest Bancorp, Inc., Suburban

Table of Contents

Illinois Bancorp, Inc. and Community Financial Shares, Inc., respectively. The Trusts were formed for purposes of issuing trust preferred securities to third-party investors and investing the proceeds from the issuance of the trust preferred securities and common securities solely in junior subordinated debentures issued by the Company (or assumed by the Company in connection with an acquisition), with the same maturities and interest rates as the trust preferred securities. The junior subordinated debentures are the sole assets of the Trusts. In each Trust, the common securities represent approximately 3% of the junior subordinated debentures and the trust preferred securities represent approximately 97% of the junior subordinated debentures.

The Trusts are reported in the Company’s consolidated financial statements as unconsolidated subsidiaries. Accordingly, in the Consolidated Statements of Condition, the junior subordinated debentures issued by the Company to the Trusts are reported as liabilities and the common securities of the Trusts, all of which are owned by the Company, are included in investment securities.

The following table provides a summary of the Company’s junior subordinated debentures as of March 31, 2021. The junior subordinated debentures represent the par value of the obligations owed to the Trusts.

Total					$	253,566		2.39	%

The junior subordinated debentures totaled $253.6 million at March 31, 2021, December 31, 2020 and March 31, 2020.

The interest rates on the variable rate junior subordinated debentures are based on the three-month LIBOR rate and reset on a quarterly basis. At March 31, 2021, the weighted average contractual interest rate on the junior subordinated debentures was 2.39%. The Company entered into interest rate swaps with an aggregate notional value of $210.0 million to hedge the variable cash flows on certain junior subordinated debentures. The hedge-adjusted contractual interest rate on the junior subordinated debentures as of March 31, 2021, was 3.98%. Distributions on the common and preferred securities issued by the Trusts are payable quarterly at a rate per annum equal to the interest rates being earned by the Trusts on the junior subordinated debentures. Interest expense on the junior subordinated debentures is deductible for income tax purposes.

The Company has guaranteed the payment of distributions and payments upon liquidation or redemption of the trust preferred securities, in each case to the extent of funds held by the Trusts. The Company and the Trusts believe that, taken together, the obligations of the Company under the guarantees, the junior subordinated debentures, and other related agreements provide, in the aggregate, a full, irrevocable and unconditional guarantee, on a subordinated basis, of all of the obligations of the Trusts under the trust preferred securities. Subject to certain limitations, the Company has the right to defer the payment of interest on the junior subordinated debentures at any time, or from time to time, for a period not to exceed 20 consecutive quarters. The trust preferred securities are subject to mandatory redemption, in whole or in part, upon repayment of the junior subordinated debentures at maturity or their earlier redemption. The junior subordinated debentures are redeemable in whole or in part prior to maturity at any time after the earliest redemption dates shown in the table, and earlier at the discretion of the Company if certain conditions are met, and, in any event, only after the Company has obtained Federal Reserve Bank ("FRB") approval, if then required under applicable guidelines or regulations.

At March 31, 2021, the Company included $245.5 million of the junior subordinated debentures, net of common securities, in Tier 2 regulatory capital.

Wealth Management Revenue

Wealth management revenue is comprised of brokerage and insurance product commissions, managed money fees and trust and asset management revenue of the Company's four wealth management subsidiaries: Wintrust Investments, Great Lakes Advisors, LLC ("GLA"), The Chicago Trust Company, N.A. ("CTC") and CDEC. All wealth management revenue is recognized in the wealth management segment.

Brokerage and insurance product commissions consists primarily of commissions earned from trade execution services on behalf of customers and from selling mutual funds, insurance and other investment products to customers. For trade execution services, the Company recognizes commissions and receives payment from the brokerage customers at the point of transaction execution. Commissions received from the investment or insurance product providers are recognized at the point of sale of the product. The Company also receives trail and other commissions from providers for certain plans. These are generally based on qualifying account values and are recognized once the performance obligation, specific to each provider, is satisfied on a monthly, quarterly or annual basis.

Trust revenue is earned primarily from trust and custody services that are generally performed over time as well as fees earned on funds held during the facilitation of tax-deferred like-kind exchange transactions. Revenue is determined periodically based on a schedule of fees applied to the value of each customer account using a time-elapsed method to measure progress toward complete satisfaction of the performance obligation. Fees are typically billed on a calendar month or quarter basis in advance or in arrears depending upon the contract. Upfront fees received related to the facilitation of tax-deferred like-kind exchange transactions are deferred until the transaction is completed. Additional fees earned for certain extraordinary services performed on behalf of the customers are recognized when the service has been performed.

Asset management revenue is earned from money management and advisory services that are performed over time. Revenue is based primarily on the market value of assets under management or administration using a time-elapsed method to measure progress toward complete satisfaction of the performance obligation. Fees are typically billed on a calendar month or quarter basis in advance or in arrears depending upon the contract. Certain programs provide the customer with an option of paying fees as a percentage of the account value or incurring commission charges for each trade similar to brokerage and insurance product commissions. Trade commissions and any other fees received for additional services are recognized at a point in time once the performance obligation is satisfied.

Mortgage Broker Fees

For customers desiring a mortgage product not currently offered by the Company, the Company may refer such customers and, with permission, direct such customers' applications to certain third party mortgage brokers. Mortgage broker fees are received from these brokers for such customer referrals upon settlement of the underlying mortgage. The Company's entitlement to the consideration is contingent on the settlement of the mortgage which is highly susceptible to factors outside of the Company's influence, such as third party broker's underwriting requirements. Also, the uncertainty surrounding the consideration could be resolved in varying lengths of time, dependent upon the third party brokers. Therefore, mortgage broker fees are recognized at the settlement of the underlying mortgage when the consideration is received. Broker fees are recognized in the community banking segment.

Service Charges on Deposit Accounts

Service charges on deposit accounts include fees charged to deposit customers for various services, including account analysis services, and are based on factors such as the size and type of customer, type of product and number of transactions. The fees are based on a standard schedule of fees and, depending on the nature of the service performed, the service is performed at a point in time or over a period of a month. When the service is performed at a point in time, the Company recognizes and receives revenue when the service has been performed. When the service is performed over a period of a month, the Company recognizes and receives revenue in the month the service has been performed. Service charges on deposit accounts are recognized in the community banking segment.

Administrative Services

Administrative services revenue is earned from providing outsourced administrative services, such as data processing of payrolls, billing and cash management services, to temporary staffing service clients located throughout the United States. Fees are charged periodically (typically a payroll cycle) and computed in accordance with the contractually determined rate applied to the total gross billings administered for the period. The revenue is recognized over the period using a time-elapsed method to measure progress toward complete satisfaction of the performance obligation. Other fees are charged on a per occurrence basis as the service is provided in the billing cycle. The Company has certain contracts with customers to perform outsourced administrative services and short-term accounts receivable financing. For these contracts, the total fee is allocated between the administrative services revenue and interest income during the client onboarding process based on the specific client and services provided. Administrative services revenue is recognized in the specialty finance segment.

Card and Other Deposit Related Fees

Card related fees include interchange and merchant revenue, and fees related to debit and credit cards. Interchange revenue is related to the Company issued debit cards. Other deposit related fees primarily include pay by phone processing fees, ATM and safe deposit box fees, check order charges and foreign currency related fees. Card and deposit related fees are generally based on volume of transactions and are recognized at the point in time when the service has been performed. For any consideration that is constrained, the revenue is recognized once the uncertainty is known. Upfront fees received from certain contracts are recognized on a straight line basis over the term of the contract. Card and deposit related fees are recognized in the community banking segment.

Receivables are recognized in the period the Company provides services and when the Company's right to consideration is unconditional. Card related fee receivable is the result of volume based fee that the Company receives from a customer on an annual basis in the second quarter of each year. Payment terms on other invoiced amounts are typically 30 days or less. Contract liabilities and receivables from contracts with customers are included within the accrued interest payable and other liabilities and accrued interest receivable and other assets line items, respectively, in the Consolidated Statements of Condition.

Practical Expedients and Exemptions

The Company does not adjust the promised amount of consideration for the effects of a significant financing component if the Company expects, at contract inception, that the period between when the Company transfers a promised service to a customer and when the customer pays for that service is one year or less.

The Company recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less.

(13) Segment Information

The Company’s operations consist of three primary segments: community banking, specialty finance and wealth management.

The three reportable segments are strategic business units that are separately managed as they offer different products and services and have different marketing strategies. In addition, each segment’s customer base has varying characteristics and each segment has a different regulatory environment. While the Company’s management monitors each of the fifteen bank subsidiaries’ operations and profitability separately, these subsidiaries have been aggregated into one reportable operating segment due to the similarities in products and services, customer base, operations, profitability measures, and economic characteristics.

For purposes of internal segment profitability, management allocates certain intersegment and parent company balances. Management allocates a portion of revenues to the specialty finance segment related to loans and leases originated by the specialty finance segment and sold or assigned to the community banking segment. Similarly, for purposes of analyzing the contribution from the wealth management segment, management allocates a portion of the net interest income earned by the community banking segment on deposit balances of customers of the wealth management segment to the wealth management segment. See Note 9 — Deposits, for more information on these deposits. Finally, expenses incurred at the Wintrust parent company are allocated to each segment based on each segment's risk-weighted assets.

The segment financial information provided in the following table has been derived from the internal profitability reporting system used by management to monitor and manage the financial performance of the Company. The accounting policies of the segments are substantially similar to those described in “Summary of Significant Accounting Policies” in Note 1 of the Company’s 2020 Form 10-K. The Company evaluates segment performance based on after-tax profit or loss and other appropriate profitability measures common to each segment.

(14) Derivative Financial Instruments

The Company primarily enters into derivative financial instruments as part of its strategy to manage its exposure to changes in interest rates. Derivative instruments represent contracts between parties that result in one party delivering cash to the other party based on a notional amount and an underlying term (such as a rate, security price or price index) as specified in the contract. The amount of cash delivered from one party to the other is determined based on the interaction of the notional amount of the contract with the underlying term. Derivatives are also implicit in certain contracts and commitments.

The derivative financial instruments currently used by the Company to manage its exposure to interest rate risk include: (1) interest rate swaps and collars to manage the interest rate risk of certain fixed and variable rate assets and variable rate liabilities; (2) interest rate lock commitments provided to customers to fund certain mortgage loans to be sold into the secondary market; (3) forward commitments for the future delivery of such mortgage loans to protect the Company from adverse changes in interest rates and corresponding changes in the value of mortgage loans held-for-sale; (4) covered call options to economically hedge specific investment securities and receive fee income effectively enhancing the overall yield on such securities to compensate for net interest margin compression; and (5) options and swaps to economically hedge a portion of the

Table of Contents

fair value adjustments related to the Company's mortgage servicing rights portfolio. The Company also enters into derivatives (typically interest rate swaps) with certain qualified borrowers to facilitate the borrowers’ risk management strategies and concurrently enters into mirror-image derivatives with a third party counterparty, effectively making a market in the derivatives for such borrowers. Additionally, the Company enters into foreign currency contracts to manage foreign exchange risk associated with certain foreign currency denominated assets.

The Company recognizes derivative financial instruments in the consolidated financial statements at fair value regardless of the purpose or intent for holding the instrument. The Company records derivative assets and derivative liabilities on the Consolidated Statements of Condition within accrued interest receivable and other assets and accrued interest payable and other liabilities, respectively. Changes in the fair value of derivative financial instruments are either recognized in income or in shareholders’ equity as a component of accumulated other comprehensive income or loss depending on whether the derivative financial instrument qualifies for hedge accounting and, if so, whether it qualifies as a fair value hedge or cash flow hedge.

Changes in fair values of derivatives accounted for as fair value hedges are recorded in income in the same period and in the same income statement line as changes in the fair values of the hedged items that relate to the hedged risk(s). Changes in fair values of derivative financial instruments accounted for as cash flow hedges are recorded as a component of accumulated other comprehensive income or loss, net of deferred taxes, and reclassified to earnings when the hedged transaction affects earnings. Changes in fair values of derivative financial instruments not designated in a hedging relationship pursuant to ASC 815 are reported in non-interest income during the period of the change. Derivative financial instruments are valued by a third party and are corroborated by comparison with valuations provided by the respective counterparties. Fair values of certain mortgage banking derivatives (interest rate lock commitments and forward commitments to sell mortgage loans) are estimated based on changes in mortgage interest rates from the date of the loan commitment. The fair value of foreign currency derivatives is computed based on changes in foreign currency rates stated in the contract compared to those prevailing at the measurement date.

The table below presents the fair value of the Company’s derivative financial instruments as of March 31, 2021, December 31, 2020 and March 31, 2020:

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to net interest income and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. Interest rate collars designated as cash flow hedges involve the receipt of amounts in which the interest rate specified in the contract exceeds the agreed upon cap strike price or the payment of amounts in which the interest rate specified in the contract is below the agreed upon floor strike price at the end of each period.

Table of Contents

As of March 31, 2021, the Company had 27 interest rate swap derivatives designated as cash flow hedges of variable rate deposits and certain junior subordinated debentures, and one interest rate collar derivative designated as a cash flow hedge of the Company's variable rate Term Facility. When the relationship between the hedged item and hedging instrument is highly effective at achieving offsetting changes in cash flows attributable to the hedged risk, changes in the fair value of these cash flow hedges are recorded in accumulated other comprehensive income or loss and are subsequently reclassified to interest expense as interest payments are made on such variable rate deposits. The changes in fair value (net of tax) are separately disclosed in the Consolidated Statements of Comprehensive Income.

The table below provides details on these cash flow hedges, summarized by derivative type and maturity, as of March 31, 2021:

Amount of income (loss) recognized in other comprehensive income	44,096		(39,783)
Unrealized gain (loss) at end of period	$	19,259	$	(56,636)

As of March 31, 2021, the Company estimates that during the next twelve months $19.9 million will be reclassified from accumulated other comprehensive income or loss as an increase to interest expense.

Fair Value Hedges of Interest Rate Risk

Interest rate swaps designated as fair value hedges involve the payment of fixed amounts to a counterparty in exchange for the Company receiving variable payments over the life of the agreements without the exchange of the underlying notional amount. As of March 31, 2021, the Company has 17 interest rate swaps with an aggregate notional amount of $167.5 million that were designated as fair value hedges primarily associated with fixed rate commercial and industrial and commercial real estate loans as well as life insurance premium finance receivables.

For derivatives designated and that qualify as fair value hedges, the net gain or loss from the entire change in the fair value of the derivative instrument is recognized in the same income statement line item as the earnings effect, including the net gain or loss, of the hedged item (interest income earned on fixed rate loans) when the hedged item affects earnings.

Non-Designated Hedges

The Company does not use derivatives for speculative purposes. Derivatives not designated as accounting hedges are used to manage the Company’s economic exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements of ASC 815. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings.

Interest Rate Derivatives—Periodically, the Company may purchase interest rate cap derivatives designed to act as an economic hedge of the risk of the negative impact on its fixed-rate loan portfolios from rising interest rates, most notably the LIBOR index. As of March 31, 2021, the Company held interest rate caps with an aggregate notional value of $1.0 billion.

Additionally, the Company has interest rate derivatives, including swaps and option products, resulting from a service the Company provides to certain qualified borrowers. The Company’s banking subsidiaries execute certain derivative products (typically interest rate swaps) directly with qualified commercial borrowers to facilitate their respective risk management strategies. For example, these arrangements allow the Company’s commercial borrowers to effectively convert a variable rate loan to a fixed rate. In order to minimize the Company’s exposure on these transactions, the Company simultaneously executes offsetting derivatives with third parties. In most cases, the offsetting derivatives have mirror-image terms, which result in the positions’ changes in fair value substantially offsetting through earnings each period. However, to the extent that the derivatives are not a mirror-image and because of differences in counterparty credit risk, changes in fair value will not completely offset resulting in some earnings impact each period. Changes in the fair value of these derivatives are included in other non-interest income. At March 31, 2021, the Company had interest rate derivative transactions with an aggregate notional amount of approximately $9.0 billion (all interest rate swaps and caps with customers and third parties) related to this program. These interest rate derivatives had maturity dates ranging from April 2021 to February 2045.

Mortgage Banking Derivatives—These derivatives include interest rate lock commitments provided to customers to fund certain mortgage loans to be sold into the secondary market and forward commitments for the future delivery of such loans. It is the Company’s practice to enter into forward commitments for the future delivery of a portion of our residential mortgage loan production when interest rate lock commitments are entered into in order to economically hedge the effect of future changes in interest rates on its commitments to fund the loans as well as on its portfolio of mortgage loans held-for-sale. The Company’s mortgage banking derivatives have not been designated as being in hedge relationships. At March 31, 2021, the Company had forward commitments to sell mortgage loans with an aggregate notional amount of approximately $2.3 billion and interest rate lock commitments with an aggregate notional amount of approximately $1.1 billion. The fair values of these derivatives were

37

Table of Contents

estimated based on changes in mortgage rates from the dates of the commitments. Changes in the fair value of these mortgage banking derivatives are included in mortgage banking revenue.

Foreign Currency Derivatives—These derivatives include foreign currency contracts used to manage the foreign exchange risk associated with foreign currency denominated assets and transactions. Foreign currency contracts, which include spot and forward contracts, represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date. As a result of fluctuations in foreign currencies, the U.S. dollar-equivalent value of the foreign currency denominated assets or forecasted transactions increase or decrease. Gains or losses on the derivative instruments related to these foreign currency denominated assets or forecasted transactions are expected to substantially offset this variability. As of March 31, 2021, the Company held foreign currency derivatives with an aggregate notional amount of approximately $3.8 million.

Other Derivatives—Periodically, the Company will sell options to a bank or dealer for the right to purchase certain securities held within the banks’ investment portfolios (covered call options). These option transactions are designed primarily to mitigate overall interest rate risk and to increase the total return associated with the investment securities portfolio. These options do not qualify as accounting hedges pursuant to ASC 815, and, accordingly, changes in fair value of these contracts are recognized as other non-interest income. There were no covered call options outstanding as of March 31, 2021, December 31, 2020 or March 31, 2020.

Periodically, the Company will purchase options for the right to purchase securities not currently held within the banks' investment portfolios or enter into interest rate swaps in which the Company elects to not designate such derivatives as hedging instruments. These option and swap transactions are designed primarily to economically hedge a portion of the fair value adjustments related to the Company's mortgage servicing rights portfolio. The gain or loss associated with these derivative contracts are included in mortgage banking revenue. There were no such options or swaps outstanding as of March 31, 2021.

Amounts included in the Consolidated Statements of Income related to derivative instruments not designated in hedge relationships were as follows:

Credit Risk

Derivative instruments have inherent risks, primarily market risk and credit risk. Market risk is associated with changes in interest rates and credit risk relates to the risk that the counterparty will fail to perform according to the terms of the agreement. The amounts potentially subject to market and credit risks are the streams of interest payments under the contracts and the market value of the derivative instrument and not the notional principal amounts used to express the volume of the transactions. Market and credit risks are managed and monitored as part of the Company's overall asset-liability management process, except that the credit risk related to derivatives entered into with certain qualified borrowers is managed through the Company's standard loan underwriting process since these derivatives are secured through collateral provided by the loan agreements. Actual exposures are monitored against various types of credit limits established to contain risk within parameters. When deemed necessary, appropriate types and amounts of collateral are obtained to minimize credit exposure.

The Company has agreements with certain of its interest rate derivative counterparties that contain cross-default provisions, which provide that if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company also has agreements with certain of its derivative counterparties that contain a provision allowing the counterparty to terminate the derivative positions if the Company fails to maintain its status as a well or adequately capitalized institution, which would require the Company to settle its obligations under the agreements. As of March 31, 2021, the fair value of interest rate derivatives in a net liability position that were subject to such agreements, which includes accrued interest related to these agreements, was $131.4 million. If the Company had breached any of these provisions and the derivatives were terminated as a result, the Company would have been required to settle its obligations under the agreements at the termination value and would

38

Table of Contents

have been required to pay any additional amounts due in excess of amounts previously posted as collateral with the respective counterparty.

The Company is also exposed to the credit risk of its commercial borrowers who are counterparties to interest rate derivatives with the banks. This counterparty risk related to the commercial borrowers is managed and monitored through the banks' standard underwriting process applicable to loans since these derivatives are secured through collateral provided by the loan agreement. The counterparty risk associated with the mirror-image swaps executed with third parties is monitored and managed in connection with the Company's overall asset liability management process.

The Company records interest rate derivatives subject to master netting agreements at their gross value and does not offset derivative assets and liabilities on the Consolidated Statements of Condition.

(15) Fair Values of Assets and Liabilities

The Company measures, monitors and discloses certain of its assets and liabilities on a fair value basis. These financial assets and financial liabilities are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the inputs used to determine fair value. These levels are:

•Level 1—unadjusted quoted prices in active markets for identical assets or liabilities.

•Level 2—inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•Level 3—significant unobservable inputs that reflect the Company’s own assumptions that market participants would use in pricing the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

A financial instrument’s categorization within the above valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the assets or liabilities. The following is a description of the valuation methodologies used for the Company’s assets and liabilities measured at fair value on a recurring basis.

Available-for-sale debt securities, trading account securities and equity securities with readily determinable fair value—Fair values for available-for-sale debt securities, trading account securities and equity securities with readily determinable fair value are typically based on prices obtained from independent pricing vendors. Securities measured with these valuation techniques are generally classified as Level 2 of the fair value hierarchy. Typically, standard inputs such as benchmark yields, reported trades for similar securities, issuer spreads, benchmark securities, bids, offers and reference data including market research publications are used to fair value these securities. When these inputs are not available, broker/dealer quotes may be obtained by the vendor to determine the fair value of the security. We review the vendor’s pricing methodologies to determine if

39

Table of Contents

observable market information is being used, versus unobservable inputs. Fair value measurements using significant inputs that are unobservable in the market due to limited activity or a less liquid market are classified as Level 3 in the fair value hierarchy. The fair value of U.S. Treasury securities and certain equity securities with readily determinable fair value are based on unadjusted quoted prices in active markets for identical securities. As such, these securities are classified as Level 1 in the fair value hierarchy.

The Company’s Investment Operations Department is responsible for the valuation of Level 3 available-for-sale debt securities. The methodology and variables used as inputs in pricing Level 3 securities are derived from a combination of observable and unobservable inputs. The unobservable inputs are determined through internal assumptions that may vary from period to period due to external factors, such as market movement and credit rating adjustments.

At March 31, 2021, the Company classified $101.7 million of municipal securities as Level 3. These municipal securities are bond issues for various municipal government entities primarily located in the Chicago metropolitan area and southern Wisconsin and are privately placed, non-rated bonds without CUSIP numbers. The Company also classified $1.8 million of U.S. Government agency securities as Level 3 at March 31, 2021. The Company’s methodology for pricing these securities focuses on three distinct inputs: equivalent rating, yield and other pricing terms. To determine the rating for a given non-rated investment debt security, the Investment Operations Department references a rated, publicly issued bond by the same issuer if available. A reduction is then applied to the rating obtained from the comparable bond, as the Company believes if liquidated, a non-rated bond would be valued less than a similar bond with a verifiable rating. The reduction applied by the Company is one complete rating grade (i.e. a “AA” rating for a comparable bond would be reduced to “A” for the Company’s valuation). For bond issues without comparable bond proxies, a rating of "BBB" was assigned. In the first quarter of 2021, all of the ratings derived by the Investment Operations Department using the above process were “BBB” or better. The fair value measurement noted above is sensitive to the rating input, as a higher rating typically results in an increased valuation. The remaining pricing inputs used in the bond valuation are observable. Based on the rating determined in the above process, Investment Operations obtains a corresponding current market yield curve available to market participants. Other terms including coupon, maturity date, redemption price, number of coupon payments per year, and accrual method are obtained from the individual bond term sheets. Certain municipal bonds held by the Company at March 31, 2021 are continuously callable. When valuing these bonds, the fair value is capped at par value as the Company assumes a market participant would not pay more than par for a continuously callable bond. To determine the rating for the U.S. Government agency securities, the Investment Operations Department assigned a “AAA” rating as it is guaranteed by the U.S. government.

Mortgage loans held-for-sale—The fair value of mortgage loans held-for-sale is determined by reference to investor price sheets for loan products with similar characteristics. As such, these loans are classified as Level 2 in the fair value hierarchy.

Loans held-for-investment—The fair value for loans in which the Company elected the fair value option is estimated by discounting future scheduled cash flows for the specific loan through maturity, adjusted for estimated credit losses and prepayments. The Company uses a discount rate based on the actual coupon rate of the underlying loan. At March 31, 2021, the Company classified $6.4 million of loans held-for-investment as Level 3. The weighted average discount rate used as an input to value these loans at March 31, 2021 was 2.38% with discount rates applied ranging from 2%-3%. The higher the rate utilized to discount estimated future cash flows, the lower the fair value measurement. As noted above, the fair value estimate also includes assumptions of prepayment speeds and credit losses. The Company included a prepayments speed assumption of 12.99% at March 31, 2021. Prepayment speeds are inversely related to the fair value of these loans as an increase in prepayment speeds results in a decreased valuation. Additionally, the weighted average credit discount used as an input to value the specific loans was 0.26% with credit loss discount ranging from 0%-3% at March 31, 2021.

MSRs—Fair value for MSRs is determined utilizing a valuation model which calculates the fair value of each servicing rights based on the present value of estimated future cash flows. The Company uses a discount rate commensurate with the risk associated with each servicing rights, given current market conditions. At March 31, 2021, the Company classified $124.3 million of MSRs as Level 3. The weighted average discount rate used as an input to value the pool of MSRs at March 31, 2021 was 9.88% with discount rates applied ranging from 3%-19%. The higher the rate utilized to discount estimated future cash flows, the lower the fair value measurement. The fair value of MSRs was also estimated based on other assumptions including prepayment speeds and the cost to service. Prepayment speeds ranged from 6%-92% or a weighted average prepayment speed of 12.99%. Further, for current and delinquent loans, the Company assumed a weighted average cost of servicing of $76 and $354, respectively, per loan. Prepayment speeds and the cost to service are both inversely related to the fair value of MSRs as an increase in prepayment speeds or the cost to service results in a decreased valuation. See Note 8 - Mortgage Servicing Rights (“MSRs”) for further discussion of MSRs.

Derivative instruments—The Company’s derivative instruments include interest rate swaps, caps and collars, commitments to fund mortgages for sale into the secondary market (interest rate locks), forward commitments to end investors for the sale of

Table of Contents

mortgage loans and foreign currency contracts. Interest rate swaps, caps and collars are valued by a third party, using models that primarily use market observable inputs, such as yield curves, and are classified as Level 2 in the fair value hierarchy. The credit risk associated with derivative financial instruments that are subject to master netting agreements is measured on a net basis by counterparty portfolio. The fair value for mortgage-related derivatives is based on changes in mortgage rates from the date of the commitments. The fair value of foreign currency derivatives is computed based on change in foreign currency rates stated in the contract compared to those prevailing at the measurement date.

At March 31, 2021, the Company classified $25.6 million of derivative assets related to interest rate locks as Level 3. The fair value of interest rate locks is based on prices obtained for loans with similar characteristics from third parties, adjusted for the pull-through rate, which represents the Company’s best estimate of the likelihood that a committed loan will ultimately fund. The weighted-average pull-through rate at March 31, 2021 was 86% with pull-through rates applied ranging from 14% to 100%. Pull-through rates are directly related to the fair value of interest rate locks as an increase in the pull-through rate results in an increased valuation.

Nonqualified deferred compensation assets—The underlying assets relating to the nonqualified deferred compensation plan are included in a trust and primarily consist of non-exchange traded institutional funds which are priced based by an independent third party service. These assets are classified as Level 2 in the fair value hierarchy.

The aggregate remaining contractual principal balance outstanding as of March 31, 2021, December 31, 2020 and March 31, 2020 for mortgage loans held-for-sale measured at fair value under ASC 825 was $1.2 billion, $1.2 billion and $618.7 million, respectively, while the aggregate fair value of mortgage loans held-for-sale was $1.3 billion, $1.3 billion and $656.9 million, for the same respective periods, as shown in the above tables. There were $115.2 million of loans past due greater than 90 days and still accruing in the mortgage loans held-for-sale portfolio as of March 31, 2021 compared to $134.1 million as of December 31, 2020 and $358,000 as of March 31, 2020. All of the loans past due greater than 90 days and still accruing as of March 31, 2021 were individual delinquent mortgage loans bought back from GNMA at the unconditional option of the Company as servicer for those loans.

The changes in Level 3 assets measured at fair value on a recurring basis during the three months ended March 31, 2021 and 2020 are summarized as follows:

Also, the Company may be required, from time to time, to measure certain other assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from impairment charges on individual assets. For assets measured at fair value on a nonrecurring basis that were still held in the balance sheet at the end of the period, the following table provides the carrying value of the related individual assets or portfolios at March 31, 2021:

	March 31, 2021								Three Months Ended March 31, 2021 Fair Value Losses Recognized, net

(1)Fair value losses recognized, net on other real estate owned include valuation adjustments and charge-offs during the respective period.

Individually assessed loans—In accordance with ASC 326, the allowance for credit losses for loans and other financial assets held at amortized cost should be measured on a collective or pooled basis when such assets exhibit similar risk characteristics. In instances in which a financial asset does not exhibit similar risk characteristics to a pool, the Company is required to measure such allowance for credit losses on an individual asset basis. For the Company's loan portfolio, nonaccrual loans and TDRs are considered to not exhibit similar risk characteristics as pools and thus are individually assessed. Credit losses are measured by estimating the fair value of the loan based on the present value of expected cash flows, the market price of the loan, or the fair value of the underlying collateral. Individually assessed loans are considered a fair value measurement where an allowance for credit loss is established based on the fair value of collateral. Appraised values on relevant real estate properties, which may require adjustments to market-based valuation inputs, are generally used on foreclosure probable and collateral-dependent loans within the real estate portfolios.

The Company’s Managed Assets Division is primarily responsible for the valuation of Level 3 inputs of individually assessed loans. For more information on individually assessed loans refer to Note 6 – Allowance for Credit Losses. At March 31, 2021, the Company had $124.4 million of individually assessed loans classified as Level 3. Of the $124.4 million of individually assessed loans, $87.8 million were measured at fair value based on the underlying collateral of the loan as shown in the table above. The remaining $36.6 million were valued based on discounted cash flows in accordance with ASC 310.

Other real estate owned —Other real estate owned is comprised of real estate acquired in partial or full satisfaction of loans and is included in other assets. Other real estate owned is recorded at its estimated fair value less estimated selling costs at the date of transfer, with any excess of the related loan balance over the fair value less expected selling costs charged to the allowance for loan losses. Subsequent changes in value are reported as adjustments to the carrying amount and are recorded in other non-interest expense. Gains and losses upon sale, if any, are also charged to other non-interest expense. Fair value is generally based on third party appraisals and internal estimates that are adjusted by a discount representing the estimated cost of sale and is therefore considered a Level 3 valuation.

The Company’s Managed Assets Division is primarily responsible for the valuation of Level 3 inputs for other real estate owned. At March 31, 2021, the Company had $15.8 million of other real estate owned classified as Level 3. The unobservable

input applied to other real estate owned relates to the 10% reduction to the appraisal value representing the estimated cost of sale of the foreclosed property. A higher discount for the estimated cost of sale results in a decreased carrying value.

The valuation techniques and significant unobservable inputs used to measure both recurring and non-recurring Level 3 fair value measurements at March 31, 2021 were as follows:

Not all the financial instruments listed in the table above are subject to the disclosure provisions of ASC Topic 820, as certain assets and liabilities result in their carrying value approximating fair value. These include cash and cash equivalents, interest bearing deposits with banks, brokerage customer receivables, FHLB and FRB stock, accrued interest receivable and accrued interest payable and non-maturity deposits.

The following methods and assumptions were used by the Company in estimating fair values of financial instruments that were not previously disclosed.

Held-to-maturity securities. Held-to-maturity securities include U.S. Government-sponsored agency securities and municipal bonds issued by various municipal government entities primarily located in the Chicago metropolitan area and southern Wisconsin. Fair values for held-to-maturity securities are typically based on prices obtained from independent pricing vendors. In accordance with ASC 820, the Company has generally categorized these held-to-maturity securities as a Level 2 fair value measurement. Fair values for certain other held-to-maturity securities are based on the bond pricing methodology discussed previously related to certain available-for-sale securities. In accordance with ASC 820, the Company has categorized these held-to-maturity securities as a Level 3 fair value measurement.

Loans held-for-investment, at amortized cost. Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are analyzed by type such as commercial, residential real estate, etc. Each category is further segmented by interest rate type (fixed and variable) and term. For variable-rate loans that reprice frequently, estimated fair values are based on carrying values. The fair value of residential loans is based on secondary market sources for securities backed by similar loans, adjusted for differences in loan characteristics. The fair value for other fixed rate loans is estimated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect credit and interest rate

risks inherent in the loan. In accordance with ASC 820, the Company has categorized loans as a Level 3 fair value measurement.

Deposits with stated maturities. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently in effect for deposits of similar remaining maturities. In accordance with ASC 820, the Company has categorized deposits with stated maturities as a Level 3 fair value measurement.

FHLB advances. The fair value of FHLB advances is obtained from the FHLB which uses a discounted cash flow analysis based on current market rates of similar maturity debt securities to discount cash flows. In accordance with ASC 820, the Company has categorized FHLB advances as a Level 3 fair value measurement.

Subordinated notes. The fair value of the subordinated notes is based on a market price obtained from an independent pricing vendor. In accordance with ASC 820, the Company has categorized subordinated notes as a Level 2 fair value measurement.

Junior subordinated debentures. The fair value of the junior subordinated debentures is based on the discounted value of contractual cash flows. In accordance with ASC 820, the Company has categorized junior subordinated debentures as a Level 3 fair value measurement.

(16) Stock-Based Compensation Plans

In May 2015, the Company’s shareholders approved the 2015 Stock Incentive Plan (“the 2015 Plan”) which provides for the issuance of up to 5,485,000 shares of common stock. The 2015 Plan replaced the 2007 Stock Incentive Plan (“the 2007 Plan”) which replaced the 1997 Stock Incentive Plan (“the 1997 Plan”). The 2015 Plan, the 2007 Plan and the 1997 Plan are collectively referred to as “the Plans.” The 2015 Plan has substantially similar terms to the 2007 Plan and the 1997 Plan. Awards granted under the Plans for which common shares are not issued by reason of cancellation, forfeiture, lapse of such award or settlement of such award in cash, are again available under the 2015 Plan. All grants made after the approval of the 2015 Plan are made pursuant to the 2015 Plan. As of March 31, 2021, approximately 951,000 shares were available for future grants assuming the maximum number of shares are issued for the performance awards outstanding. The Plans cover substantially all employees of Wintrust. The Compensation Committee of the Board of Directors administers all stock-based compensation programs and authorizes all awards granted pursuant to the Plans.

The Plans permit the grant of incentive stock options, non-qualified stock options, stock appreciation rights, stock awards, restricted share or unit awards, performance awards and other incentive awards valued in whole or in part by reference to the Company’s common stock, all on a stand alone, combination or tandem basis. The Company historically awarded stock-based compensation in the form of time-vested non-qualified stock options and time-vested restricted share unit awards (“restricted shares”). The grants of options provide for the purchase of shares of the Company’s common stock at the fair market value of the stock on the date the options are granted. Stock options generally vest ratably over periods of three to five years and have a maximum term of seven years from the date of grant. Restricted shares entitle the holders to receive, at no cost, shares of the Company’s common stock. Restricted shares generally vest over periods of one to five years from the date of grant.

Beginning in 2011, the Company has awarded annual grants under the Long-Term Incentive Program (“LTIP”), which is administered under the Plans. The LTIP is designed in part to align the interests of management with the interests of shareholders, foster retention, create a long-term focus based on sustainable results and provide participants with a target long-term incentive opportunity. LTIP grants in 2021 consisted of a combination of performance-based stock awards with a performance condition metric, performance-based stock awards with a market condition metric and time vested restricted shares, and in 2020 consisted of a combination of performance-based stock awards and performance-based cash awards (both with a performance condition metric) and time vested restricted shares. LTIP grants from 2017 through 2019 consisted of a combination of performance-based stock awards and performance-based cash awards, and prior to 2017, nonqualified stock options were in the mix of award types. Stock options granted under the LTIP have a term of seven years and generally vested equally over three years based on continued service. Performance-based stock and cash awards granted under the LTIP are contingent upon the achievement of pre-established long-term performance goals set in advance by the Compensation Committee over a three-year period starting at the beginning of each calendar year. Performance-based stock awards with a market condition metric are contingent on the total shareholder return performance over a three-year period starting at the beginning of each calendar year relative to the KBW Regional Bank Index. These performance awards are granted at a target level, and based on the Company’s achievement of the pre-established long-term goals, the actual payouts can range from 0% to a maximum of 150% of the target award. The awards typically vest in the quarter after the end of the performance period upon certification of the payout by the Compensation Committee of the Board of Directors. Holders of performance-based stock awards are entitled to receive, at no cost, the shares earned based on the achievement of the pre-established long-term goals.

Holders of restricted share awards and performance-based stock awards received under the Plans are not entitled to vote or receive cash dividends (or cash payments equal to the cash dividends) on the underlying common shares until the awards are vested and shares are issued. Shares that are vested but not issuable pursuant to deferred compensation arrangements accrue additional shares based on the value of dividends otherwise paid. Except in limited circumstances, these awards are canceled upon termination of employment without any payment of consideration by the Company.

Stock-based compensation is measured as the fair value of an award on the date of grant, and the measured cost is recognized over the period which the recipient is required to provide service in exchange for the award. The fair value of restricted share and performance-based stock awards with a performance condition metric is determined based on the average of the high and low trading prices on the grant date. The fair value of performance stock awards with a market condition metric is estimated using a Monte Carlo simulation model and the fair value of stock options is estimated using a Black-Scholes option-pricing model. The Monte Carlo simulation model and the Black-Scholes option-pricing model require the input of highly subjective assumptions and are sensitive to changes in the award's expected life and the price volatility of the underlying stock, which can materially affect the fair value estimates. Management periodically reviews and adjusts the assumptions used to calculate the fair value of such awards when granted. No options have been granted since 2016.

Stock based compensation is recognized based upon the number of awards that are ultimately expected to vest, taking into account expected forfeitures. In addition, for performance-based awards with a performance metric, an estimate is made of the number of shares expected to vest as a result of actual performance against the performance criteria in the award to determine the amount of compensation expense to recognize. The estimate is re-evaluated quarterly and total compensation expense is adjusted for any change in estimate in the current period. Stock-based compensation expense recognized in the Consolidated Statements of Income was $2.9 million in the first quarter of 2021 and $(2.8) million in the first quarter of 2020.

ITEM 2

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the financial condition of Wintrust Financial Corporation and its subsidiaries (collectively, "Wintrust" or the "Company") as of March 31, 2021 compared with December 31, 2020 and March 31, 2020, and the results of operations for the three month period ended March 31, 2021 and March 31, 2020, should be read in conjunction with the unaudited consolidated financial statements and notes contained in this report and the risk factors discussed under Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 ("2020 Form 10-K") and in Part II, Item 1A, of this Form 10-Q. This discussion contains forward-looking statements that involve risks and uncertainties and, as such, future results could differ significantly from management’s current expectations. See the last section of this discussion for further information on forward-looking statements.

Introduction

Wintrust is a financial holding company that provides traditional community banking services, primarily in the Chicago metropolitan area, southern Wisconsin and northwest Indiana, and operates other financing businesses on a national basis and in Canada through several non-bank business units. Additionally, Wintrust offers a full array of wealth management services primarily to customers in the Chicago metropolitan area, southern Wisconsin and northwest Indiana.

Overview

Impact of COVID-19

In March 2020, the outbreak of COVID-19 was recognized as a global pandemic by the World Health Organization, resulting in unprecedented uncertainty and volatility in world-wide financial markets. Governments' actions calling for shelter in place and social distancing led to rapid changes in business revenues, increased unemployment, and negatively impacted consumer activity, all of which have impacted the Company. Although vaccines are now being widely distributed, the COVID-19 pandemic, including the emergence of variant strains of the virus, may continue to impact the Company's future results.

The Company activated its pandemic response plan in early March 2020, as well as applicable elements of its business continuity plan. In order to protect the health of our customers and employees, and in accordance with applicable government directives, we modified certain of our business protocols to direct employees to work from home unless their role required them to be on site, in which case we have implemented enhanced safety measures including social distancing, enhanced cleaning and sanitization, and certain personal protective equipment. With the phased reopening of certain state and municipal areas, the Company implemented a comprehensive plan that permits certain remote employees to return to their respective workplaces, where enhanced safety measures also have been implemented. At present, however, the majority of the Company’s workforce continues to work remotely on a nearly daily basis.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act was enacted. The CARES Act includes appropriations and other measures designed to address the impact of the COVID-19 pandemic, including the Paycheck Protection Program ("PPP"), which is designed to aid eligible small and medium-sized businesses through federally-guaranteed loans distributed through certain banks, under the administration of the Small Business Administration ("SBA"). From the date the Company began accepting applications, April 3, 2020, through March 31, 2021, the Company secured authorization from the SBA and funded over 19,400 PPP loans with a carrying balance of approximately $4.8 billion. PPP loans are forgivable under certain circumstances, including the borrower’s use of certain loan proceeds to fund employee payroll during a specific period (e.g., eight weeks, 24 weeks) following disbursement of the borrower’s PPP loan. From the loans originated under the program, the Company has generated net fees of $143.1 million to be recognized over the life of the PPP loan adjusted for estimated prepayments.

All of our three primary business segments (community banking, specialty finance and wealth management), have been uniquely impacted and we expect will continue to be impacted by the COVID-19 pandemic, requiring the implementation of certain responses as circumstances evolve.  As non-exclusive examples of such impacts, our community banking business, including our mortgage business, has received borrower requests for temporary payment relief including payment deferrals. As of March 31, 2021, loans totaling approximately $253.7 million were modified as a result of COVID-19 disruption to our borrowers. Our insurance premium finance business is impacted by certain state legislation prohibiting canceling of insurance policies for designated periods. Our wealth management business is impacted by increased stock market volatility.

Table of Contents

Given the continued uncertainty regarding future economic conditions, the Company has taken a number of actions to help ensure that it has adequate liquidity and capital to manage through the COVID-19 pandemic, including issuing fixed-rate reset non-cumulative perpetual preferred stock, Series E, liquidation preference $25,000 per share (the “Series E Preferred Stock”) as part of a public offering of depositary shares, each representing a 1/1,000th interest in a share of Series E Preferred Stock (the “Depositary Shares”). We believe the Company currently has adequate liquidity and capital to effectively manage through the COVID-19 pandemic. However, we will continue to prudently evaluate available liquidity sources if necessary.

We continue to monitor the impact of COVID-19 closely; however, the extent to which the COVID-19 pandemic will impact our operations and financial conditions remains highly uncertain. Please refer to Part II, Item 1A, “Risk Factors” of this Form 10-Q for additional information.

First Quarter Highlights

The Company recorded net income of $153.1 million for the first quarter of 2021 compared to $62.8 million in the first quarter of 2020. The results for the first quarter of 2021 demonstrate continued momentum on our operating strengths, including strong loan growth driven by the Company's continued participation in the PPP, stable net interest income despite the current interest rate environment, significant production by the Company's mortgage banking business, and a release of credit reserves attributable to positive changes in the macroeconomic forecasts in addition to improvement in portfolio characteristics.

The Company increased its loan portfolio from $27.8 billion at March 31, 2020 and $32.1 billion at December 31, 2020 to $33.2 billion at March 31, 2021. The increase in the current period compared to the prior periods was primarily a result of the Company’s participation in PPP lending as well as growth in several portfolios, including the commercial, industrial and other, commercial real estate and life insurance premium finance receivables portfolios. For more information regarding changes in the Company’s loan portfolio, see Financial Condition – Interest Earning Assets and Note 5 - Loans of the Consolidated Financial Statements in Item 1 of this report.

The Company recorded net interest income of $261.9 million in the first quarter of 2021 compared to $261.4 million in the first quarter of 2020. This slight increase in net interest income recorded in the first quarter of 2021 compared to the first quarter of 2020 resulted primarily from growth in earning assets, specifically a $5.5 billion increase in average loans. The increase in average earnings assets was partially offset by a reduced net interest margin between periods. Net interest margin of 2.53% (2.54% on a fully taxable-equivalent basis, non-GAAP) in the first quarter of 2021 compared to 3.12% (3.14% on a fully taxable-equivalent basis, non-GAAP) in the first quarter of 2020 was primarily due to lower rates on earning assets in the first quarter of 2021 from the declining interest rate environment (see "Net Interest Income" for further detail).

Non-interest income totaled $186.5 million in the first quarter of 2021 compared to $113.2 million in the first quarter of 2020. This increase was primarily the result of higher mortgage banking revenue (see “Non-Interest Income” for further detail).

Non-interest expense totaled $286.9 million in the first quarter of 2021, increasing $52.2 million, or 22%, compared to the first quarter of 2020. The increase compared to the first quarter of 2020 was primarily attributable to higher expenses associated with the Company's long term incentive program and higher commissions related to its mortgage business due to increased origination volume (see “Non-Interest Expense” for further detail).

Management considers the maintenance of adequate liquidity to be important to the management of risk. Accordingly, during the first quarter of 2021, the Company continued its practice of maintaining appropriate funding capacity to provide the Company with adequate liquidity for its ongoing operations. In this regard, the Company benefited from its strong deposit base, a liquid short-term investment portfolio and its access to funding from a variety of external funding sources. At March 31, 2021, the Company had approximately $3.8 billion in overnight liquid funds and interest-bearing deposits with banks.

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

(2)See following section titled, “Supplemental Non-GAAP 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.

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

Table of Contents

SUPPLEMENTAL NON-GAAP FINANCIAL MEASURES/RATIOS

The accounting and reporting policies of the Company 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 useful measurements of the Company's core net income.

Critical Accounting Policies

The Company’s Consolidated Financial Statements are prepared in accordance with GAAP in the United States and prevailing practices of the banking industry. Application of these principles requires management to make estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes. Certain policies and accounting principles inherently have a greater reliance on the use of estimates, assumptions and judgments, and as such have a greater possibility that changes in those estimates and assumptions could produce financial results that are materially different than originally reported. Estimates, assumptions and judgments are necessary when assets and liabilities are required to be recorded at fair value, when a decline in the value of an asset not carried on the financial statements at fair value warrants an impairment write-down or valuation reserve to be established, or when an asset or liability needs to be recorded contingent upon a future event, are based on information available as of the date of the financial statements; accordingly, as information changes, the financial statements could reflect different estimates and assumptions. Management views critical accounting policies to be those which are highly dependent on subjective or complex judgments, estimates and assumptions, and where changes in those estimates and assumptions could have a significant impact on the financial statements. Management currently views critical accounting policies to include the determination of the allowance for credit losses, including the allowance for loan losses, the allowance for unfunded commitment losses and the allowance for held-to-maturity securities losses, estimations of fair value, the valuations required for impairment testing of goodwill, the valuation and accounting for derivative instruments and income taxes as the accounting areas that require the most subjective and complex judgments, and as such could be the most subject to revision as new information becomes available. For a more detailed discussion on these critical accounting policies, see “Summary of Critical Accounting Policies” beginning on page 59 of the Company’s 2020 Form 10-K.

The COVID-19 pandemic, specifically the uncertainty related to the ultimate magnitude of impact on the economy and banking industry, is expected to impact many of the estimates, assumptions and judgments noted above that are used by management. This could result in volatility in the related accounting estimates, which will directly impact the Company's financial results. Please refer to Management's Discussion and Analysis of Financial Condition and Results of Operation - Overview section of this report for additional discussion of the impact of the COVID-19 pandemic.

Net Income

Net income for the quarter ended March 31, 2021 totaled $153.1 million, an increase of $90.3 million, or 144%, compared to the quarter ended March 31, 2020. On a per share basis, net income for the first quarter of 2021 totaled $2.54 per diluted common share compared to $1.04 for the first quarter of 2020.

The increase in net income for the first quarter of 2021 as compared to the same period in the prior year is primarily attributable to increased mortgage banking revenue, a release of credit reserves attributable to positive changes in the Company’s macroeconomic forecasts in addition to improvement in portfolio characteristics and higher net interest income, partially offset by increased salaries and employee benefits expense. See "Net Interest Income", "Non-interest Income", "Non-interest Expense" and "Loan Portfolio and Asset Quality" for further detail.

Net Interest Income

The primary source of the Company’s revenue is net interest income. Net interest income is the difference between interest income and fees on earning assets, such as loans and securities, and interest expense on the liabilities to fund those assets, including interest bearing deposits and other borrowings. The amount of net interest income is affected by both changes in the level of interest rates, and the amount and composition of earning assets and interest bearing liabilities.

(1)Includes interest-bearing deposits with banks, federal funds sold and securities purchased under resale agreements.

(2)Investment securities includes investment securities classified as available-for-sale and held-to-maturity, and equity securities with readily determinable fair values. Equity securities without readily determinable fair values are included within other assets.

(3)Interest income on tax-advantaged loans, trading securities and investment securities reflects a tax-equivalent adjustment based on the marginal federal corporate tax rate in effect as of the applicable period. The total adjustments for the three months ended March 31, 2021, December 31, 2020 and March 31, 2020 were $884,000, $857,000 and $1.4 million, respectively.

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

(5)Loans, net of unearned income, include non-accrual loans.

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

(7)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.

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

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

Wealth management revenue increased in the first quarter of 2021 as compared to the first quarter of 2020 due to an increase in trust and asset management fees. Trust and asset management fees are based primarily on the market value of the assets under management or administration as well as the volume of tax-deferred like-kind exchange services provided during a period. Such

59

Table of Contents

revenue increased in the first quarter of 2021 primarily as a result of market appreciation related to managed money accounts with fees based on assets under management and higher asset levels from new customers and new financial advisors as compared to the first quarter of 2020. 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 of Wintrust Investments and fees from tax-deferred like-kind exchange services provided by the Chicago Deferred Exchange Company.

The Company recognized net gains on investment securities in the first quarter of 2021 and net losses in the first quarter of 2020. This difference was primarily a result of unrealized gains in the first quarter of 2021 compared to unrealized losses in the first quarter of 2020 from market appreciation on market sensitive equity securities with readily determinable fair value.

Operating lease income increased in the first quarter of 2021 as compared to the first quarter of 2020. This increase is primarily due to a $1.5 million gain recognized on sale of lease assets in the first quarter of 2021.

Mortgage banking revenue increased in the first quarter of 2021 as compared to the first quarter of 2020 as a result of an increase in loans originated for sale resulting in higher production revenue. Mortgage loans originated for sale totaled $2.2 billion in the first quarter of 2021 as compared to $1.2 billion in the first quarter of 2020. 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. The Company records MSRs at fair value on a recurring basis.

During the first quarter of 2021, the fair value of the mortgage servicing rights portfolio increased due to increased capitalization of $24.6 million during the first quarter and a positive fair value adjustment of $18.0 million. This was partially offset due to a reduction in value of $10.2 million due to payoffs and paydowns of the existing portfolio. Starting in 2019, the Company purchased options and entered into interest rate swaps to economically hedge a portion of the fair value changes recorded in earnings related to its MSRs portfolio. During the second quarter of 2020, the Company terminated these interest rate swaps. There were no such options or interest rate swaps outstanding as of March 31, 2021.

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 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. There were no outstanding call option contracts at March 31, 2021 and March 31, 2020.

Miscellaneous revenue decreased in the first quarter of 2021 as compared to the first quarter of 2020 due to a decrease in syndication fees and other miscellaneous income, partially offset by increased partnership income.

Total Non-interest Expense	$	286,889	$	234,641	$	52,248	22	%

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

Total salaries and employee benefits expense increased in the first quarter of 2021 compared to the first quarter of 2020 primarily due to increased salaries and commissions and incentive compensation expense. Salaries increased as a result of increased staffing costs to support mortgage origination and investment in technology related services to satisfy customer demands and create efficiencies in operations. Commissions and incentive compensation increased primarily due to higher expenses associated with the Company’s long term incentive program and higher commissions related to its mortgage and wealth management businesses.

Equipment expense increased in the first quarter of 2021 compared to the first quarter of 2020 as a result of higher software license fees and software and computer depreciation expense.

Data processing expense decreased in the first quarter of 2021 compared to the first quarter of 2020 as the majority of conversion charges related to previously completed acquisitions was recognized in 2020.

Advertising and marketing expenses decreased in the first quarter of 2021 compared to the first quarter of 2020 as a result of decreased sponsorship costs due to the cancellation of events, including sports sponsorships, as a result of the COVID-19 pandemic. Marketing costs are incurred to promote the Company's brand, commercial banking capabilities and various products, and to attract loans and deposits and 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.

FDIC insurance expense increased in the first quarter of 2021 compared to the first quarter of 2020 as a result of higher assessment rates impacted by declines in the Tier 1 Leverage Ratio at the Company's bank affiliates as a result of asset growth, including PPP loans.

Income Taxes

The Company recorded income tax expense of $53.7 million in the first quarter of 2021 compared to $24.3 million in the first quarter of 2020. The effective tax rates were 25.97% in the first quarter of 2021 compared to 27.87% in the first quarter of 2020.

The effective tax rates were impacted by the tax effects related to share-based compensation which fluctuate based on the Company’s stock price and timing of employee stock option exercises and vesting of other share-based awards. The Company recorded tax benefits of $1.3 million in the first quarter of 2021 and additional tax expense of $486,000 in the first quarter of 2020 related to share-based compensation.

Operating Segment Results

As described in Note 13 to the Consolidated Financial Statements in Item 1, the Company’s operations consist of three primary segments: community banking, specialty finance and wealth management. The Company’s profitability is primarily dependent on the net interest income, provision for credit losses, non-interest income and operating expenses of its community banking segment. For purposes of internal segment profitability, management allocates certain intersegment and parent company balances. Management allocates a portion of revenues to the specialty finance segment related to loans and leases originated by the specialty finance segment and sold or assigned to the community banking segment. Similarly, for purposes of analyzing the contribution from the wealth management segment, management allocates a portion of the net interest income earned by the community banking segment on deposit balances of customers of the wealth management segment to the wealth management segment. Finally, expenses incurred at the Wintrust parent company are allocated to each segment based on each segment's risk-weighted assets.

The community banking segment’s net interest income for the quarter ended March 31, 2021 totaled $203.5 million as compared to $206.8 million for the same period in 2020, a decrease of $3.3 million, or 2%. The decrease in the three month period is primarily attributable to compression of the net interest margin attributable to the decrease in interest rates in the environment. The community banking segment’s non-interest income totaled $147.3 million in the first quarter of 2021, an increase of $66.3 million, or 82%, when compared to the first quarter of 2020 total of $81.0 million. The increase in the three month period is primarily the result of increased mortgage banking revenue from significantly increased mortgage originations during 2021. A release of credit reserves of $46.6 million was recorded in the community banking segment’s provision for credit losses for the quarter ended March 31, 2021, compared to a provision for credit losses of $51.7 million for the same period in 2020. The decrease in provision for credit losses of $98,249 was attributable to positive changes in the macroeconomic forecasts in addition to improvement in portfolio characteristics. The community banking segment’s net income for the quarter ended March 31, 2021 totaled $121.8 million, an increase of $87.2 million as compared to net income in the first quarter of 2020 of $34.6 million.

The specialty finance segment's net interest income totaled $44.9 million for the quarter ended March 31, 2021, compared to $40.7 million for the same period in 2020, an increase of $4.2 million, or 10%. The increase is primarily attributable to growth in earning assets on the premium finance receivables portfolios. The specialty finance segment’s non-interest income totaled $23.1 million and $21.3 million for the three month periods ended March 31, 2021 and 2020, respectively. The increase in non-interest income in the three month period is primarily the result of higher originations and increased balances related to the commercial premium finance portfolio and growth in business from the Company's leasing division. Our commercial premium finance operations, life insurance finance operations, lease financing operations and accounts receivable finance operations accounted for 41%, 28%, 27% and 4%, respectively, of the total revenues of our specialty finance business for the three month period ended March 31, 2021. The net income of the specialty finance segment for the quarter ended March 31, 2021 totaled $23.9 million as compared to $22.1 million for the quarter ended March 31, 2020.

The wealth management segment reported net interest income of $7.4 million for the first quarter of 2021 compared to $7.8 million in the same quarter of 2020, a decrease of $343,000, or 4%. Net interest income for this segment is primarily comprised of an allocation of the net interest income earned by the community banking segment on non-interest-bearing and interest-bearing wealth management customer account balances on deposit at the banks. Wealth management customer account balances on deposit at the banks averaged $2.2 billion and $1.8 billion in the first three months of 2021 and 2020, respectively. This segment recorded non-interest income of $30.3 million for the first quarter of 2021 compared to $24.1 million for the first quarter of 2020. Distribution of wealth management services through each bank continues to be a focus of the Company. The Company is committed to growing the wealth management segment in order to better service its customers and create a more diversified revenue stream. The wealth management segment’s net income totaled $7.4 million for the first quarter of 2021 compared to $6.1 million for the first quarter of 2020.

Financial Condition

Total assets were $45.7 billion at March 31, 2021, representing an increase of $6.9 billion, or 18%, when compared to March 31, 2020 and an increase of approximately $601.4 million, or 5% on an annualized basis, when compared to December 31, 2020. Total funding, which includes deposits, all notes and advances, including secured borrowings and the junior subordinated debentures, was $40.3 billion at March 31, 2021, $39.5 billion at December 31, 2020, and $33.8 billion at March 31, 2020.

(1)Includes non-accrual loans.

(2)Liquidity management assets include investment securities, other securities, interest earning deposits with banks, federal funds sold and securities purchased under resale agreements.

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

Mortgage loans held-for-sale. Average mortgage loans held-for-sale totaled $1.2 billion in the first quarter of 2021, compared to $893.4 million in the fourth quarter of 2020 and $403.3 million in the first quarter of 2020. These balances represent mortgage loans awaiting subsequent sale in the secondary market with such sales eliminating the interest-rate risk associated with these loans, as they are predominantly long-term fixed rate loans, and provides a source of non-interest revenue. The increase in average balance from 2020 to 2021 was primarily due to continued high mortgage production in 2020 and the first quarter of 2021 due to the low interest rate environment as well as higher balances repurchased by the Company under the early buyout option available for loans sold to GNMA with servicing retained. See “Loan Portfolio and Asset Quality” section below in this Item 2 for additional discussion of these early buyout options.

Loans, net of unearned income. Average total loans, net of unearned income, totaled $32.4 billion in the first quarter of 2021, increasing $5.5 billion, or 20%, from the first quarter of 2020 and $659.6 million, or 8% on an annualized basis, from the fourth quarter of 2020. Average commercial loans, excluding PPP loans, totaled $9.2 billion in the first quarter of 2021, and increased $766.0 million, or 9%, over the average balance in the first quarter of 2020 and $276.2 million, or 13% on an annualized basis, over the average balance in the fourth quarter of 2020. Average commercial PPP loans totaled $3.1 billion in the first quarter of 2021, relatively unchanged from the fourth quarter of 2020. Average commercial real estate loans totaled $8.5 billion in the first quarter of 2021, increasing $371.3 million, or 5%, over the first quarter of 2020. Combined, the commercial and commercial real estate loan categories comprised 64% of the average loan portfolio in the first quarter of 2021 as compared to 64% in the

64

Table of Contents

fourth quarter of 2020 and 61% in the first quarter of 2020. Growth realized in these aggregated categories for the first quarter of 2021 as compared to the sequential and prior year periods is primarily attributable to PPP lending and increased business development efforts.

Home equity loan portfolio averaged $408.6 million in the first quarter of 2021, and decreased $90.8 million, or 18% from the average balance of $499.4 million in same period of 2020. The decrease in the home equity loan portfolio is primarily the result of borrowers preferring to finance through longer term, low rate mortgage loans. The Company has been actively managing its home equity portfolio to ensure that diligent pricing, appraisal and other underwriting activities continue to exist.

Residential real estate loans averaged $1.3 billion in the first quarter of 2021, and increased $57.8 million, or 5% from the average balance of $1.2 billion in same period of 2020. Additionally, compared to the quarter ended December 31, 2020, the average balance increased $169.1 million, or 61% on an annualized basis. The increase in average balance compared to both periods was partially due to the Company deciding to allocate more balances from its mortgage production for investment instead of for subsequent sale and servicing in the secondary market.

Average premium finance receivables totaled $9.9 billion in the first quarter of 2021, and accounted for 31% of the Company’s average total loans. The increase during the first quarter of 2021 compared to the first quarter of 2020 was the result of continued originations within the portfolio due to hardening insurance market conditions driving a higher average size of new commercial insurance premium finance receivables as well as effective marketing and customer servicing. Approximately $2.8 billion of premium finance receivables were originated in the first quarter of 2021 compared to $2.5 billion during the same period of 2020. Premium finance receivables consist of a commercial portfolio and a life portfolio comprising approximately 40% and 60%, respectively, of the average total balance of premium finance receivables for the first quarter of 2021, and 40% and 60%, respectively, for the first quarter of 2020.

Other loans represent a wide variety of personal and consumer loans to individuals. Consumer loans generally have shorter terms and higher interest rates than mortgage loans but generally involve more credit risk due to the type and nature of the collateral.

Liquidity management assets. Funds that are not utilized for loan originations are used to purchase investment securities and short term money market investments, to sell as federal funds and to maintain in interest bearing deposits with banks. Average liquidity management assets accounted for 20% and 19% of total average earning assets in the first quarter of 2021 and 2020, respectively. Average liquidity management assets increased $2.0 billion in the first quarter of 2021 compared to the same period of 2020. The balances of these assets can fluctuate based on management’s ongoing effort to manage liquidity and for asset liability management purposes. The Company will continue to prudently evaluate and utilize liquidity sources as needed, including the management of availability with the FHLB and FRB and utilization of the revolving credit facility with unaffiliated banks. Please refer to Management's Discussion and Analysis of Financial Condition and Results of Operation - Overview and - Liquidity sections of this report for additional discussion of the impact of the COVID-19 pandemic.

Other earning assets. Other earning assets include brokerage customer receivables and trading account securities. In the normal course of business, Wintrust Investments' activities involve the execution, settlement, and financing of various securities transactions. Wintrust Investments customer securities activities are transacted on either a cash or margin basis. In margin transactions, Wintrust Investments, under an agreement with an out-sourced securities firm, extends credit to its customers, subject to various regulatory and internal margin requirements, collateralized by cash and securities in customers’ accounts. In connection with these activities, Wintrust Investments executes and the out-sourced firm clears customer transactions relating to the sale of securities not yet purchased, substantially all of which are transacted on a margin basis subject to individual exchange regulations. Such transactions may expose Wintrust Investments to off-balance-sheet risk, particularly in volatile trading markets, in the event margin requirements are not sufficient to fully cover losses that customers may incur. In the event a customer fails to satisfy its obligations, Wintrust Investments under the agreement with the outsourced securities firm, may be required to purchase or sell financial instruments at prevailing market prices to fulfill the customers’ obligations. Wintrust Investments seeks to control the risks associated with its customers’ activities by requiring customers to maintain margin collateral in compliance with various regulatory and internal guidelines. Wintrust Investments monitors required margin levels daily and, pursuant to such guidelines, requires customers to deposit additional collateral or to reduce positions when necessary.

We make commercial loans for many purposes, including working capital lines, which are generally renewable annually and supported by business assets, personal guarantees and additional collateral. Such loans may vary in size based on customer need. In addition, the Company has participated in the PPP starting in the second quarter of 2020. Commercial business lending

is generally considered to involve a slightly higher degree of risk than traditional consumer bank lending. Primarily as a result of improvements in the Company’s macroeconomic forecasts and improvement in portfolio characteristics, our allowance for credit losses in our commercial loan portfolio decreased to $95.6 million as of March 31, 2021 compared to $107.3 million as of March 31, 2020.

Our commercial real estate loans are generally secured by a first mortgage lien and assignment of rents on the property. Since most of our bank branches are located in the Chicago metropolitan area and southern Wisconsin, 82.2% of our commercial real estate loan portfolio is located in this region as of March 31, 2021. We have been able to effectively manage our total non-performing commercial real estate loans. As of March 31, 2021, our allowance for credit losses related to this portfolio was $181.8 million compared to $112.8 million as of March 31, 2020. The increase in the allowance for credit losses is primarily due to declining expectations between the two reporting dates primarily related to the Commercial Real Estate Price Index.

The Company also participates in mortgage warehouse lending, which is included above within commercial, industrial and other, by providing interim funding to unaffiliated mortgage bankers to finance residential mortgages originated by such bankers for sale into the secondary market. The Company’s loans to the mortgage bankers are secured by the business assets of the mortgage companies as well as the specific mortgage loans funded by the Company, after they have been pre-approved for purchase by third party end lenders. The Company may also provide interim financing for packages of mortgage loans on a bulk basis in circumstances where the mortgage bankers desire to competitively bid on a number of mortgages for sale as a package in the secondary market. Amounts advanced with respect to any particular mortgage loan are usually required to be repaid within 21 days.

Home equity loans. Our home equity loans and lines of credit are originated by each of our banks in their local markets where we have a strong understanding of the underlying real estate value. Our banks monitor and manage these loans, and we conduct an automated review of all home equity loans and lines of credit at least twice per year. This review collects current credit performance for each home equity borrower and identifies situations where the credit strength of the borrower is declining, or where there are events that may influence repayment, such as tax liens or judgments. Our banks use this information to manage loans that may be higher risk and to determine whether to obtain additional credit information or updated property valuations.

The rates we offer on new home equity lending are based on several factors, including appraisals and valuation due diligence, in order to reflect inherent risk, and we place additional scrutiny on larger home equity requests. In a limited number of cases, we issue home equity credit together with first mortgage financing, and requests for such financing are evaluated on a combined basis. It is not our practice to advance more than 85% of the appraised value of the underlying asset, which ratio we refer to as the loan-to-value ratio, or LTV ratio, and a majority of the credit we previously extended, when issued, had an LTV ratio of less than 80%. Our home equity loan portfolio has performed well in light of the ongoing volatility in the overall residential real estate market.

Residential real estate. Our residential real estate portfolio includes one- to four-family adjustable rate mortgages, construction loans to individuals and bridge financing loans for qualifying customers as well as certain long-term fixed rate loans. As of March 31, 2021, our residential loan portfolio totaled $1.4 billion, or 4% of our total outstanding loans.

Our adjustable rate mortgages relate to properties located principally in the Chicago metropolitan area and southern Wisconsin or vacation homes owned by local residents. These adjustable rate mortgages are often non-agency conforming. Adjustable rate mortgage loans decrease the interest rate risk we face on our mortgage portfolio. However, this risk is not eliminated due to the fact that such loans generally provide for periodic and lifetime limits on the interest rate adjustments among other features. Additionally, adjustable rate mortgages may pose a higher risk of delinquency and default because they require borrowers to make larger payments when interest rates rise. As of March 31, 2021, $21.6 million of our residential real estate mortgages, or 1.5% of our residential real estate loan portfolio were classified as nonaccrual, no loans were 90 or more days past due and still accruing, $14.7 million were 30 to 89 days past due, or 1.0%, and $1.4 billion were current, or 97.4%. We believe that since our loan portfolio consists primarily of locally originated loans, and since the majority of our borrowers are longer-term customers with lower LTV ratios, we face a relatively low risk of borrower default and delinquency.

Due to interest rate risk considerations, we generally sell in the secondary market loans originated with long-term fixed rates, for which we receive fee income. We may also selectively retain certain of these loans within our banks’ own portfolios where they are non-agency conforming, or where the terms of the loans make them favorable to retain. A portion of the loans we sold into the secondary market were sold with the servicing of those loans retained. The amount of loans serviced for others as of March 31, 2021 and 2020 was $11.5 billion and $8.3 billion, respectively. All other mortgage loans sold into the secondary market were sold without the retention of servicing rights.

The Government National Mortgage Association ("GNMA") optional repurchase programs allow financial institutions acting as servicers to buyout individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution was the original transferor of such loans. At the option of the servicer and without prior authorization from GNMA, the servicer may repurchase such delinquent loans for an amount equal to the remaining principal balance of the loan. Under FASB ASC Topic 860, “Transfers and Servicing,” this early buyout option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When the Company is deemed to have regained effective control over these loans under the unconditional repurchase option and the expected benefit of the potential repurchase is more than trivial, the loans can no longer be reported as sold and must be brought back onto the balance sheet as loans at fair value, regardless of whether the Company intends to exercise the early buyout option. These rebooked loans are reported as loans held-for-investment, part of the residential real estate portfolio, with the offsetting liability being reported in accrued interest payable and other liabilities. Rebooked GNMA loans held-for-investment amounted to $45.5 million at March 31, 2021, compared to $132.7 million balance at March 31, 2020. The decrease in balance from March 31, 2020 to March 31, 2021 was the result of the Company increasing its exercise of such early buyout options subsequent to March 31, 2020 and continuing such practice into 2021. When the early buyout option on these rebooked GNMA loans is exercised, the repurchased loans continue to be carried at fair value. Additionally, such loans typically transfer to mortgage loans held-for-sale at the time of early buyout as the Company’s intent is to cure and resell such loans subsequent to repurchase from GNMA. As of March 31, 2021, early buyout exercised mortgage loans held-for-sale totaled $369.4 million compared to $14.5 million as of March 31, 2020.

It is not our current practice to underwrite, and we have no plans to underwrite, subprime, Alt A, no or little documentation loans, or option ARM loans. As of March 31, 2021, approximately $550,000 of our mortgage loans consist of interest-only loans.

Premium finance receivables – commercial. FIRST Insurance Funding and FIFC Canada originated approximately $2.4 billion in commercial insurance premium finance receivables in the first quarter of 2021 as compared to $2.2 billion of originations in the first quarter of 2020. FIRST Insurance Funding and FIFC Canada make loans to businesses to finance the insurance premiums they pay on their commercial insurance policies. The loans are originated by working through independent medium and large insurance agents and brokers located throughout the United States and Canada. The insurance premiums financed are primarily for commercial customers’ purchases of liability, property and casualty and other commercial insurance.

This lending involves relatively rapid turnover of the loan portfolio and high volume of loan originations. Because of the indirect nature of this lending through third party agents and brokers and because the borrowers are located nationwide and in Canada, this segment is more susceptible to third party fraud than relationship lending. The Company performs ongoing credit and other reviews of the agents and brokers, and performs various internal audit steps to mitigate against the risk of any fraud. The majority of these loans are purchased by the banks in order to more fully utilize their lending capacity as these loans generally provide the banks with higher yields than alternative investments.

Premium finance receivables—life insurance. Wintrust Life Finance originated approximately $330.3 million in life insurance premium finance receivables in the first quarter of 2021 as compared to $290.9 million of originations in the first quarter of 2020. The Company continues to experience increased competition and pricing pressure within the current market. These loans are originated directly with the borrowers with assistance from life insurance carriers, independent insurance agents, financial advisors and legal counsel. The life insurance policy is the primary form of collateral. In addition, these loans often are secured with a letter of credit, marketable securities or certificates of deposit. In some cases, Wintrust Life Finance may make a loan that has a partially unsecured position.

Consumer and other. Included in the consumer and other loan category is a wide variety of personal and consumer loans to individuals. The banks originate consumer loans in order to provide a wider range of financial services to their customers. Consumer loans generally have shorter terms and higher interest rates than mortgage loans but generally involve more credit risk than mortgage loans due to the type and nature of the collateral.

Past Due Loans and Non-Performing Assets

Our ability to manage credit risk depends in large part on our ability to properly identify and manage problem loans. To do so, the Company operates a credit risk rating system under which our credit management personnel assigns a credit risk rating to each loan at the time of origination and review loans on a regular basis to determine each loan’s credit risk rating on a scale of 1 through 10 with higher scores indicating higher risk. The credit risk rating structure used is shown below:

1 Rating —	Minimal Risk (Loss Potential – none or extremely low) (Superior asset quality, excellent liquidity, minimal leverage)
2 Rating —	Modest Risk (Loss Potential demonstrably low) (Very good asset quality and liquidity, strong leverage capacity)
3 Rating —	Average Risk (Loss Potential low but no longer refutable) (Mostly satisfactory asset quality and liquidity, good leverage capacity)
4 Rating —	Above Average Risk (Loss Potential variable, but some potential for deterioration) (Acceptable asset quality, little excess liquidity, modest leverage capacity)
5 Rating —	Management Attention Risk (Loss Potential moderate if corrective action not taken) (Generally acceptable asset quality, somewhat strained liquidity, minimal leverage capacity)
6 Rating —	Special Mention (Loss Potential moderate if corrective action not taken) (Assets in this category are currently protected, potentially weak, but not to the point of substandard classification)
7 Rating —	Substandard Accrual (Loss Potential distinct possibility that the bank may sustain some loss, but no discernable impairment) (Must have well defined weaknesses that jeopardize the liquidation of the debt)
8 Rating —	Substandard Non-accrual (Loss Potential well documented probability of loss, including potential impairment) (Must have well defined weaknesses that jeopardize the liquidation of the debt)
9 Rating —	Doubtful (Loss Potential extremely high) (These assets have all the weaknesses in those classified “substandard” with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of current existing facts, conditions, and values, highly improbable)
10 Rating —	Loss (fully charged-off) (Loans in this category are considered fully uncollectible.)

Each loan officer is responsible for monitoring his or her loan portfolio, recommending a credit risk rating for each loan in his or her portfolio and ensuring the credit risk ratings are appropriate. These credit risk ratings are then ratified by the bank’s chief credit officer and/or concurrence credit officer. Credit risk ratings are determined by evaluating a number of factors including a borrower’s financial strength, cash flow coverage, collateral protection and guarantees. The Company maintains an internal loan review function as well as utilizes a third-party loan review provider to independently review a portion of the loan portfolio to evaluate the appropriateness of management-assigned credit risk ratings. These ratings are subject to further review at each of our bank subsidiaries by the applicable regulatory authority, including the FRB of Chicago and the Office of the Comptroller of the Currency ("OCC"), and are also reviewed by our internal audit staff.

The Company’s Problem Loan Reporting system includes all loans with credit risk ratings of 6 through 9. This system is designed to provide an on-going detailed tracking mechanism for each problem loan. Once management determines that a loan has deteriorated to a point where it has a credit risk rating of 6 or worse, the Company’s Managed Asset Division performs an overall credit and collateral review. As part of this review, all underlying collateral is identified and the valuation methodology is analyzed and tracked. As a result of this initial review by the Company’s Managed Asset Division, the credit risk rating is reviewed and a portion of the outstanding loan balance may be deemed uncollectible and, as a result, no longer share similar risk characteristics as its related pool. If that is the case, the individual loan is considered collateral dependent and individually assessed for an allowance for credit loss. The Company’s individual assessment utilizes an independent re-appraisal of the collateral (unless such a third-party evaluation is not possible due to the unique nature of the collateral, such as a closely-held business or thinly traded securities). In the case of commercial real estate collateral, an independent third party appraisal is ordered by the Company’s Real Estate Services Group to determine if there has been any change in the underlying collateral value. These independent appraisals are reviewed by the Real Estate Services Group and sometimes by independent third party valuation experts and may be adjusted depending upon market conditions.

Through the credit risk rating process, loans are reviewed to determine if they are performing in accordance with the original contractual terms. If the borrower has failed to comply with the original contractual terms, further action may be required by the Company, including a downgrade in the credit risk rating, movement to non-accrual status or a charge-off. If the Company

70

determines that a loan amount or portion thereof is uncollectible, the loan’s credit risk rating is immediately downgraded to an 8 or 9 and the uncollectible amount is charged-off. Any loan that has a partial charge-off continues to be assigned a credit risk rating of an 8 or 9 for the duration of time that a balance remains outstanding. The Company undertakes a thorough and ongoing analysis to determine if additional impairment and/or charge-offs are appropriate and to begin a workout plan for the credit to minimize actual losses. In determining the appropriate charge-off for collateral-dependent loans, the Company considers the results of appraisals for the associated collateral.

The Company’s approach to workout plans and restructuring loans is built on the credit-risk rating process. A modification of a loan with an existing credit risk rating of 6 or worse or a modification of any other credit, which will result in a restructured credit risk rating of 6 or worse must be reviewed for TDR classification. In that event, our Managed Assets Division conducts an overall credit and collateral review. A modification of a loan is considered to be a TDR if both (1) the borrower is experiencing financial difficulty and (2) for economic or legal reasons, the bank grants a concession to a borrower that it would not otherwise consider. The modification of a loan where the credit risk rating is 5 or better both before and after such modification is not considered to be a TDR. Based on the Company’s credit risk rating system, it considers that borrowers whose credit risk rating is 5 or better are not experiencing financial difficulties and therefore, are not considered TDRs.

TDRs are individually assessed at the time of the modification and on a quarterly basis to measure an allowance for credit loss. The carrying amount of the loan is compared to the expected payments to be received, discounted at the loan's original rate, or for collateral dependent loans, to the fair value of the collateral. Any shortfall is recorded as a reserve.

For non-TDR loans, if based on current information and events, it is probable that the Company will be unable to collect all amounts due to it according to the contractual terms of the loan agreement, a loan is individually assessed for measuring the allowance for credit losses and if necessary, a reserve is established. In determining the appropriate reserve for collateral-dependent loans, the Company considers the results of appraisals for the associated collateral.

(1)This includes activity for premium finance receivables and indirect consumer loans.

Prior to January 1, 2020, PCI loans were excluded from non-performing loans as they continued to earn interest income from the related accretable yield, independent of performance with contractual terms of the loan. As a result of the adoption of ASU 2016-13 effective January 1, 2020, the Company transitioned all previously classified PCI loans to PCD loans, which no longer maintain the prior pools and related accounting concepts. Specifically, recognition of interest income on PCD loans is considered at the individual asset level following the Company's accrual policies, instead of based upon the entire pool of loans. As such, after adoption, the Company includes PCD loans in total non-performing loans.

Allowance for Credit Losses

The allowance for credit losses, specifically the allowance for loans losses and the allowance for unfunded commitment losses, represents management’s estimate of lifetime expected credit losses in the loan portfolio. The allowance for credit losses is determined quarterly using a methodology that incorporates important risk characteristics of each loan, as described below under “How We Determine the Allowance for Credit Losses” in this Item 2.

Management determined that the allowance for credit losses was appropriate at March 31, 2021, and that the loan portfolio is well diversified and well secured, without undue concentration in any specific risk area. While this process involves a high degree of management judgment, the allowance for credit losses is based on a comprehensive, well documented, and consistently applied analysis of the Company’s loan portfolio. This analysis takes into consideration all available information existing as of the financial statement date, including environmental factors such as economic, industry, geographical and political factors, when considered applicable. The relative level of allowance for credit losses is reviewed and compared to industry peers. This review encompasses levels of total non-performing loans, portfolio mix, portfolio concentrations and overall levels of net charge-off. Historical trending of both the Company’s results and the industry peers is also reviewed to analyze comparative significance.

Allowance for loan and unfunded loan-related commitment losses as a percentage of loans at period end, excluding PPP loans	1.08			0.91

The allowance for credit losses, as related to loans and lending-related commitments, is comprised of an allowance for loan losses, which is determined with respect to loans that we have originated, and an allowance for unfunded commitment losses. A separate allowance for held-to-maturity securities losses is measured related to such debt securities portfolio. Our allowance for unfunded commitment losses is determined with respect to funds that we have committed to lend but for which funds have not yet been disbursed and is computed using a methodology similar to that used to determine the allowance for loan losses. The allowance for unfunded lending-related commitments totaled $43.5 million and $37.4 million as of March 31, 2021 and March 31, 2020, respectively.

Additions to the allowance for credit losses are charged to earnings through the provision for credit losses. Charge-offs represent the amount of loans that have been determined to be uncollectible during a given period, and are deducted from the allowance for credit losses, and recoveries represent the amount of collections received from loans that had previously been charged off, and are credited to the allowance for credit losses. See Note 6 of the Consolidated Financial Statements presented

under Item 1 of this report for further discussion of activity within the allowance for credit losses during the period and the relationship with respective loan balances for each loan category and the total loan portfolio.

How We Determine the Allowance for Credit Losses

The allowance for credit losses is measured on a collective or pooled basis by loans that share similar risk characteristics. If the loan no longer exhibits risk characteristics similar to that of a pool, typically due to credit deterioration of the related borrower, the Company analyzes the loan for purposes of individually assessing a specific allowance for credit loss as part of the Problem Loan Reporting system review. A separate reserve is collectively measured for loans continuing to share risk characteristics and, as a result, remaining in the pools. See Note 6 of the Consolidated Financial Statements presented under Item 1 of this report for further discussion of the allowance for credit losses measurement process.

Collective Measurement

The allowance for credit losses is measured on a collective or pooled basis when similar risk characteristics exist, based upon the segmentation discussed above. The Company utilizes modeling methodologies that estimate lifetime credit loss rates on each pool, including methodologies estimating the probability of default and loss given default on specific segments. Historical credit loss history is adjusted for reasonable and supportable forecasts developed by the Company on a quantitative or qualitative basis and incorporates third party economic forecasts. Reasonable and supportable forecasts consider the macroeconomic factors that are most relevant to evaluating and predicting expected credit losses in the Company's financial assets. Currently, the Company utilizes an eight quarter forecast period using a single macroeconomic scenario provided by a third-party and reviewed within the Company's governance structure. For periods beyond the ability to develop reasonable and supportable forecasts, the Company reverts to historical loss rates at an input level, straight-line over a four quarter reversion period. Expected credit losses are measured over the contractual term of the financial asset with consideration of expected prepayments. Expected extensions, renewals or modifications of the financial asset are only considered when either 1) the expected extension, renewal or modification is contained within the existing agreement and is not unconditionally cancelable, or 2) the expected extension, renewal or modification is reasonably expected to result in a TDR. The methodologies discussed above are applied to both current asset balances on the Company's Consolidated Statements of Condition and off-balance sheet commitments (i.e. unfunded lending-related commitments).

Individual Assessment

Loans with a credit risk rating of a 6 through 9 are reviewed on a monthly basis to determine if (a) an amount is deemed uncollectible (a charge-off) or (b) it is probable that the Company will be unable to collect amounts due in accordance with the original contractual terms of the loan. In cases in which collectability is not probable, the loan is considered to no longer exhibit shared risk characteristics of a pool and as a result, is individually assessed for allowance for credit losses measurement purposes. If a loan is individually assessed, the carrying amount of the loan is compared to the expected payments to be received, discounted at the loan’s original rate, or for foreclosure-probable and collateral dependent loans, to the fair value of the collateral less the estimated cost to sell, when appropriate under accounting rules. Any shortfall is recorded as a specific reserve within the allowance for credit losses.

Home Equity, Residential Real Estate and Consumer Loans

The determination of the appropriate allowance for credit losses for home equity, residential real estate and consumer loans differs from the process used for commercial and commercial real estate loans. These portfolios utilize the weighted-average remaining maturity ("WARM") methodology. The WARM methodology is an assumption-based approach that utilizes historical loss and prepayment information as the basis to estimate prepayment and credit adjusted contractual cash flows. The Company considers a qualitative factor to adjust historical information for current conditions and reasonable and supportable forecasts. The same credit risk rating system and Problem Loan Reporting systems are used. The only significant difference is in how the credit risk ratings are assigned to these loans.

The home equity loan portfolio is reviewed on a loan by loan basis by analyzing current FICO scores of the borrowers, line availability, recent line usage, an approaching maturity and the aging status of the loan. Certain of these factors, or combination of these factors, may cause a portion of the credit risk ratings of home equity loans across all banks to be downgraded. Similar to commercial and commercial real estate loans, once a home equity loan’s credit risk rating is downgraded to a 6 through 9, the Company’s Managed Asset Division reviews and advises the subsidiary banks as to collateral valuations and as to the ultimate resolution of the credits that deteriorate to a non-accrual status to minimize losses.

Residential real estate loans that are downgraded to a credit risk rating of 6 through 9 also enter the problem loan reporting system and have the underlying collateral evaluated by the Managed Assets Division.

Premium Finance Receivables

The determination of the appropriate allowance for credit losses for premium finance receivables is an assumption-based approach focusing on historical loss rates in the portfolio, adjusted qualitatively for current macroeconomic conditions and reasonable and supportable forecasts.

Methodology in Assessing Impairment and Charge-off Amounts

In determining the amount of reserves or charge-offs associated with collateral dependent loans, the Company values the loan generally by starting with a valuation obtained from an appraisal of the underlying collateral and then deducting estimated selling costs, if appropriate, to arrive at a net appraised value. We obtain the appraisals of the underlying collateral typically on an annual basis from one of a pre-approved list of independent, third party appraisal firms. Types of appraisal valuations include “as-is,” “as-complete,” “as-stabilized,” bulk, fair market, liquidation and “retail sellout” values.

In many cases, the Company simultaneously values the underlying collateral by marketing the property to market participants interested in purchasing properties of the same type. If the Company receives offers or indications of interest, we will analyze the price and review market conditions to assess whether in light of such information the appraised value overstates the likely price and that a lower price would be a better assessment of the market value of the property and would enable us to liquidate the collateral. Additionally, the Company takes into account the strength of any guarantees or other credit enhancements, and the ability of the borrower to provide value related to those guarantees in determining the ultimate charge-off or reserve associated with any individually assessed loans. Accordingly, the Company may charge-off a loan to a value below the net appraised value if it believes that an expeditious liquidation is desirable in the circumstance and it has legitimate offers or other indications of interest to support a value that is less than the net appraised value. Alternatively, the Company may carry a loan at a value that is in excess of the appraised value if the Company has a guarantee from a borrower or other credit enhancements that the Company believes has realizable value. In evaluating the strength of any guarantee, the Company evaluates the financial wherewithal of the guarantor, the guarantor’s reputation, and the guarantor’s willingness and desire to work with the Company. The Company then conducts a review of the strength of a guarantee on a frequency established as the circumstances and conditions of the borrower warrant.

In circumstances where the Company has received an appraisal but has no third party offers or indications of interest, the Company may enlist the input of realtors in the local market as to the highest valuation that the realtor believes would result in a liquidation of the property given a reasonable marketing period of approximately 90 days. To the extent that the realtors’ indication of market clearing price under such scenario is less than the net appraised valuation, the Company may take a charge-off on the loan to a valuation that is less than the net appraised valuation.

The Company may also charge-off a loan below the net appraised valuation if the Company holds a junior mortgage position in a piece of collateral whereby the risk to acquiring control of the property through the purchase of the senior mortgage position is deemed to potentially increase the risk of loss upon liquidation due to the amount of time to ultimately market the property and the volatile market conditions. In such cases, the Company may abandon its junior mortgage and charge-off the loan balance in full.

In other cases, the Company may allow the borrower to conduct a “short sale,” which is a sale where the Company allows the borrower to sell the property at a value less than the amount of the loan. Many times, it is possible for the current owner to receive a better price than if the property is marketed by a financial institution which the market place perceives to have a greater desire to liquidate the property at a lower price. To the extent that we allow a short sale at a price below the value indicated by an appraisal, we may take a charge-off beyond the value that an appraisal would have indicated.

Other market conditions may require a reserve to bring the carrying value of the loan below the net appraised valuation such as litigation surrounding the borrower and/or property securing our loan or other market conditions impacting the value of the collateral.

Having determined the net value based on the factors such as those noted above and compared that value to the book value of the loan, the Company arrives at a charge-off amount or a specific reserve included in the allowance for credit losses. In summary, for collateral dependent loans, appraisals are used as the fair value starting point in the estimate of net value. Estimated costs to sell are deducted from the appraised value, when appropriate under current accounting rules, to arrive at the net appraised value. Although an external appraisal is the primary source of valuation utilized for charge-offs on collateral

Table of Contents

dependent loans, alternative sources of valuation may become available between appraisal dates. As a result, we may utilize values obtained through these alternative sources, which include purchase and sale agreements, legitimate indications of interest, negotiated short sales, realtor price opinions, sale of the note or support from guarantors, as the basis for charge-offs. These alternative sources of value are used only if deemed to be more representative of value based on updated information regarding collateral resolution. In addition, if an appraisal is not deemed current, a discount to appraised value may be utilized. Any adjustments from appraised value to net value are detailed and justified in an impairment analysis, which is reviewed and approved by the Company’s Managed Assets Division.

TDRs

At March 31, 2021, the Company had $56.6 million in loans modified in TDRs. The $56.6 million in TDRs represents 273 credits in which economic concessions were granted to certain borrowers to better align the terms of their loans with their current ability to pay. The balance decreased from $68.2 million representing 286 credits at December 31, 2020 and decreased from $83.6 million representing 263 credits at March 31, 2020.

Concessions were granted on a case-by-case basis working with these borrowers to find modified terms that would assist them in retaining their businesses or their homes and attempt to keep these loans in an accruing status for the Company. Typical concessions include reduction of the interest rate on the loan to a rate considered lower than market and other modification of terms including forgiveness of a portion of the loan balance, extension of the maturity date, and/or modifications from principal and interest payments to interest-only payments for a certain period. See Note 6 of the Consolidated Financial Statements in Item 1 of this report for further discussion regarding the effectiveness of these modifications in keeping the modified loans current based upon contractual terms.

Subsequent to its restructuring, any TDR that becomes nonaccrual or more than 90 days past-due and still accruing interest will be included in the Company’s non-performing loans. Each TDR was individually assessed when measuring the allowance for credit losses at March 31, 2021 and approximately $2.5 million was appropriately reserved for through the Company’s normal reserving methodology in the Company’s allowance for credit losses. Additionally, at March 31, 2021, the Company was committed to lend an additional $930,000 of funds to borrowers under the contractual terms of TDRs.

The table below presents a summary of TDRs for the respective periods, presented by loan category and accrual status:

(1)Loan was previously classified as a TDR 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.

On March 22, 2020, interagency guidance was issued titled "Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus" that encourages financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations due to the effect of COVID-19. Additionally, Section 4013 of the CARES Act further provides that a qualified loan modification is exempt by law from classification as a TDR as defined by GAAP, from the period beginning March 1, 2020 until the earlier of December 31, 2020 (subsequently extended to January 1, 2022 under CAA), or the date that is 60 days after the date on which the national emergency concerning the COVID-19 outbreak declared by the President of the United States under the National Emergencies Act (50 U.S.C. 1601 et seq.) terminates. Accordingly, we are offering short-term modifications made in response to COVID-19 to borrowers who are current and otherwise not past due. These include short-term, 180 days or less, modifications in the form of payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Modifications qualifying for the exemption from TDR classification totaled approximately $175.2 million as of March 31, 2021.

Other Real Estate Owned ("OREO")

In certain circumstances, the Company is required to take action against the real estate collateral of specific loans. The Company uses foreclosure only as a last resort for dealing with borrowers experiencing financial hardships. The Company employs extensive contact and restructuring procedures to attempt to find other solutions for our borrowers.

Total average deposits	$	37,259,921	100	%	$	36,154,677	100	%	$	29,894,646	100	%

Total average deposits for the first quarter of 2021 were $37.3 billion, an increase of $7.4 billion, or 25%, from the first quarter of 2020. The increase in average deposits is primarily attributable to additional deposits related to PPP lending and organic growth of retail deposits.

Wealth management deposits are funds from the brokerage customers of Wintrust Investments, CDEC, trust and asset management customers of the Company and brokerage customers from unaffiliated companies which have been placed into deposit accounts of the banks (“wealth management deposits” in the table above). Wealth Management deposits consist primarily of money market accounts. Consistent with reasonable interest rate risk parameters, these funds have generally been invested in loan production of the banks as well as other investments suitable for banks.

Brokered Deposits

While the Company obtains a portion of its total deposits through brokered deposits, the Company does so primarily as an asset-liability management tool to assist in the management of interest rate risk, and the Company does not consider brokered deposits to be a vital component of its current liquidity resources. Historically, brokered deposits have represented a small component of the Company’s total deposits outstanding, as set forth in the table below:

	March 31,						December 31,
(Dollars in thousands)	2021			2020			2020			2019			2018
Total deposits	$	37,872,652		$	31,461,660		$	37,092,651		$	30,107,138		$	26,094,678
Brokered deposits	2,142,257			2,181,090			1,843,227			1,011,404			1,071,562
Brokered deposits as a percentage of total deposits	5.7		%	6.9		%	5.0		%	3.4		%	4.1		%

Brokered deposits include certificates of deposit obtained through deposit brokers, deposits received through the Certificate of Deposit Account Registry Program (“CDARS”), and wealth management deposits of brokerage customers from unaffiliated companies which have been placed into deposit accounts of the banks.

Other Funding Sources

Although deposits are the Company’s primary source of funding its interest-earning assets, the Company’s ability to manage the types and terms of deposits is somewhat limited by customer preferences and market competition. As a result, in addition to deposits and the issuance of equity securities and the retention of earnings, the Company uses several other funding sources to support its growth. These sources include short-term borrowings, notes payable, FHLB advances, subordinated debt, secured borrowings and junior subordinated debentures. The Company evaluates the terms and unique characteristics of each source, as well as its asset-liability management position, in determining the use of such funding sources.

The following table sets forth, by category, the composition of the average balances of other funding sources for the quarterly periods presented:

	Three Months Ended
	March 31,		December 31,		March 31,
(In thousands)	2021		2020		2020
FHLB advances	$	1,228,433	$	1,228,425	$	951,613
Other borrowings:
Notes payable	101,653		107,000		127,978
Short-term borrowings	11,796		9,313		45,089
Secured borrowings	339,923		329,159		250,054
Other	64,816		65,253		46,456
Total other borrowings	$	518,188	$	510,725	$	469,577
Subordinated notes	436,532		436,433		436,119
Junior subordinated debentures	253,566		253,566		253,566
Total other funding sources	$	2,436,719	$	2,429,149	$	2,110,875

FHLB advances provide the banks with access to fixed-rate funds that are useful in mitigating interest rate risk and achieving an acceptable interest rate spread on fixed-rate loans or securities. Additionally, the banks have the ability to borrow shorter-term, overnight funding from the FHLB for other general purposes. FHLB advances to the banks totaled $1.2 billion at each of March 31, 2021, December 31, 2020 and March 31, 2020.

Notes payable balances represent the balances on a $200.0 million loan agreement (“Credit Agreement”) with unaffiliated banks consisting of a $50.0 million revolving credit facility (“Revolving Credit Facility”) and a $150.0 million term facility (“Term Facility”). Both the Revolving Credit Facility and the Term Facility are available for corporate purposes such as to provide capital to fund continued growth at existing bank subsidiaries, possible future acquisitions and for other general corporate matters. At March 31, 2021 and December 31, 2020, the Company had a balance under the Term Facility of $96.4 million and $101.7 million, respectively. The Company was contractually required to borrow the entire amount of the Term Facility on September 18, 2018 and all such borrowings must be repaid by September 18, 2023. At March 31, 2020, the Company had no outstanding balance under the Revolving Credit Facility.

Short-term borrowings include securities sold under repurchase agreements and federal funds purchased. These borrowings totaled $12.4 million at March 31, 2021 compared to $11.4 million at December 31, 2020 and $12.1 million at March 31, 2020. Securities sold under repurchase agreements represent sweep accounts for certain customers in connection with master repurchase agreements at the banks. This funding category typically fluctuates based on customer preferences and daily liquidity needs of the banks, their customers and the banks’ operating subsidiaries.

The balance of secured borrowings primarily represents a third party Canadian transaction (“Canadian Secured Borrowing”). Under the Canadian Secured Borrowing, the Company, through its subsidiary, FIFC Canada, sells an undivided co-ownership interest in all receivables owed to FIFC Canada to an unrelated third party in exchange for cash payments pursuant to a receivables purchase agreement (“Receivables Purchase Agreement”).

Other borrowings at March 31, 2021 include a fixed-rate promissory note issued by the Company in June 2017 and amended in March 2020 ("Fixed-Rate Promissory Note") related to and secured by three office buildings owned by the Company. At March 31, 2021, the Fixed-Rate Promissory Note had a balance of $64.7 million compared to $65.1 million at December 31, 2020 and $66.3 million at March 31, 2020. Under the Fixed-Rate Promissory Note, during the three months ended March 31, 2020, the Company made monthly principal payments and paid interest at a fixed rate of 3.36%. An amendment to the Fixed-Rate Promissory Note was executed on and became effective as of March 31, 2020. The amendment increased the principal amount to $66.4 million, reduced the interest rate to 3.00% and extended the maturity date to March 31, 2025.

At March 31, 2021, the Company had outstanding subordinated notes totaling $436.6 million compared to $436.5 million and $436.2 million outstanding at December 31, 2020 and March 31, 2020, respectively. During the second quarter of 2019, the Company issued $300.0 million of subordinated notes, receiving $296.7 million in net proceeds. The notes have a stated interest rate of 4.85% and mature in June 2029. In 2014, the Company issued $140.0 million of subordinated notes receiving $139.1 million in net proceeds. These notes have a stated interest rate of 5.00% and mature in June 2024. Subordinated notes are stated at par adjusted for unamortized costs paid related to the different issuances of such debt.

The Company had $253.6 million of junior subordinated debentures outstanding as of March 31, 2021, December 31, 2020 and March 31, 2020. The amounts reflected on the balance sheet represent the junior subordinated debentures issued to eleven trusts by the Company and equal the amount of the preferred and common securities issued by the trusts. At March 31, 2021, the Company included $245.5 million of the junior subordinated debentures, net of common securities, in Tier 2 regulatory capital.

In response to the COVID-19 pandemic, the Company will continue to manage funding sources discussed above, including the utilization of availability with the FHLB and FRB and the Revolving Credit Facility with unaffiliated banks, to access needed liquidity in a timely manner. Please refer to Management's Discussion and Analysis of Financial Condition and Results of Operation - Overview and - Liquidity sections of this report for additional discussion of the impact of the COVID-19 pandemic.

See Notes 10 and 11 of the Consolidated Financial Statements presented under Item 1 of this report for details of period end balances and other information for these various funding sources.

Shareholders’ Equity

The following tables reflect various consolidated measures of capital as of the dates presented and the capital guidelines established for a bank holding company:

(1)Reflects the Capital Conservation Buffer of 2.5%.

(2)Reflects the well-capitalized standard applicable to the Company for purposes of the Federal Reserve’s Regulation Y. The Federal Reserve has not yet revised the well-capitalized standard for BHCs to reflect the higher capital requirements imposed under the U.S. Basel III Rule or to add Common Equity Tier 1 capital ratio and Tier 1 leverage ratio requirements to this standard. As a result, the Common Equity Tier 1 capital ratio and Tier 1 leverage ratio are denoted as “N/A” in this column. If the Federal Reserve were to apply the same or a very similar well-capitalized standard to BHCs as the standard applicable to our subsidiary banks, we believe the Company’s capital ratios as of March 31, 2021 would exceed such revised well-capitalized standard.

In February 2019, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC issued a final rule to address the changes to the measurement of the allowance for credit losses, including banking organizations’ implementation of CECL. The final rule provides banking organizations the option to phase in over a three-year period the adverse effects on regulatory capital that may result from the adoption of the new accounting standard as of its date of adoption, or January 1, 2020. In March 2020, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC published an interim final rule to delay the estimated impact on regulatory capital stemming from the implementation of CECL. The interim final rule maintains the three-year transition option in the previous rule and provides banks the option to delay for two years an estimate of CECL’s effect on regulatory capital, relative to the incurred loss methodology’s effect on regulatory capital, followed by a three-year transition period (five-year transition option). The Company adopted the capital transition relief over the permissible five-year period.

The Company’s principal sources of funds at the holding company level are dividends from its subsidiaries, borrowings under its loan agreement with unaffiliated banks and proceeds from the issuances of subordinated debt and additional equity. Refer to Notes 10, 11 and 17 of the Consolidated Financial Statements in Item 1 for further information on these various funding sources. Management is committed to maintaining the Company’s capital levels above the “Well Capitalized” levels established by the FRB for bank holding companies.

The Company’s Board of Directors approves dividends from time to time, however, the ability to declare a dividend is limited by the Company's financial condition, the terms of the Company's Series D and Series E preferred stock, the terms of the Company’s Trust Preferred Securities offerings and under certain financial covenants in the Company’s revolving and term facilities. In January of 2021, the Company declared a quarterly cash dividend of $0.31 per common share. In January, April, July and October of 2020, the Company declared a quarterly cash dividend of $0.28 per common share.

In response to the COVID-19 pandemic, the Company continues to leverage its capital management framework to assess and monitor risk when making capital decisions. The Company will continuously evaluate the adequacy of capital as a result of the

LIQUIDITY

The Company manages the liquidity position of its banking operations to ensure that sufficient funds are available to meet customers’ needs for loans and deposit withdrawals. The management process includes the utilization of stress testing processes and other aspects of the Company's liquidity management framework to assess and monitor risk, and inform decision making. The liquidity to meet the demands of customers is provided by maturing assets, liquid assets that can be converted to cash and the ability to attract funds from external sources. Liquid assets refer to money market assets such as Federal funds sold and interest-bearing deposits with banks, as well as available-for-sale debt securities and equity securities with readily determinable fair values which are not pledged to secure public funds. In addition, trade date receivables represent certain sales or calls of available-for-sale securities that await cash settlement, typically in the month following the trade date.

In accordance with the liquidity management noted above, deposit growth and increases in borrowings from various sources have resulted in accumulating liquidity assets in recent periods. In the first quarter of 2021, we maintained our liquid assets to ensure that we have the balance sheet strength to serve our clients through the COVID-19 pandemic. As a result, the Company believes that it has sufficient funds and access to funds to effectively manage through the COVID-19 pandemic as well as meet its working capital and other needs. The Company will continue to prudently evaluate liquidity sources, including the management of availability with the FHLB and FRB and utilization of the revolving credit facility with unaffiliated banks. Please refer to Management's Discussion and Analysis of Financial Condition and Results of Operation -Interest-Earning Assets, -Deposits, -Other Funding Sources and -Shareholders’ Equity sections of this report for additional information regarding the Company’s liquidity position. Please refer to Management's Discussion and Analysis of Financial Condition and Results of Operation -Overview section of this report for additional discussion of the impact of the COVID-19 pandemic.

INFLATION

A banking organization’s assets and liabilities are primarily monetary. Changes in the rate of inflation do not have as great an impact on the financial condition of a bank as do changes in interest rates. Moreover, interest rates do not necessarily change at the same percentage as inflation. Accordingly, changes in inflation are not expected to have a material impact on the Company. An analysis of the Company’s asset and liability structure provides the best indication of how the organization is positioned to respond to changing interest rates. See “Quantitative and Qualitative Disclosures About Market Risk” section of this report for additional information.

ITEM 3

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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. This effort entails providing a reasonable balance between interest rate risk, credit risk, liquidity risk and maintenance of yield. Asset-liability management policies are established and monitored by management in conjunction with the boards of directors of the banks, subject to general oversight by the Risk Management Committee of the Company’s Board of Directors. The policies establish guidelines for acceptable limits on the sensitivity of the market value of assets and liabilities to changes in interest rates.

Interest rate risk arises when the maturity or re-pricing periods and interest rate indices of the interest earning assets, interest bearing liabilities, and derivative financial instruments are different. It is the risk that changes in the level of market interest rates will result in disproportionate changes in the value of, and the net earnings generated from, the Company’s interest earning assets, interest bearing liabilities and derivative financial instruments. The Company continuously monitors not only the organization’s current net interest margin, but also the historical trends of these margins. In addition, management attempts to identify potential adverse changes in net interest income in future years as a result of interest rate fluctuations by performing simulation analysis of various interest rate environments. If a potential adverse change in net interest margin and/or net income is identified, management would take appropriate actions with its asset-liability structure to mitigate these potentially adverse situations.

Since the Company’s primary source of interest bearing liabilities is from customer deposits, the Company’s ability to manage the types and terms of such deposits is somewhat limited by customer preferences and local competition in the market areas in which the banks operate. The rates, terms and interest rate indices of the Company’s interest earning assets result primarily from the Company’s strategy of investing in loans and securities that permit the Company to limit its exposure to interest rate risk, together with credit risk, while at the same time achieving an acceptable interest rate spread.

The Company’s exposure to interest rate risk is reviewed on a regular basis by management and the Risk Management Committees of the boards of directors of the banks and the Company. The objective of the review is to measure the effect on net income and to adjust balance sheet and derivative financial instruments to minimize the inherent risk while at the same time maximizing net interest income.

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 decreases 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 Scenarios at March 31, 2021, December 31, 2020 and March 31, 2020 is as follows:

Static Shock Scenarios	+200 Basis Points		+100 Basis Points		-100 Basis Points
March 31, 2021	22.0	%	10.2	%	(7.2)	%
December 31, 2020	25.0		11.6		(7.9)
March 31, 2020	22.5		10.6		(9.4)

Ramp Scenarios	+200 Basis Points		+100 Basis Points		-100 Basis Points
March 31, 2021	10.7	%	5.4	%	(3.6)	%
December 31, 2020	11.4		5.7		(3.3)
March 31, 2020	7.7		3.7		(3.8)

One method utilized by financial institutions, including the Company, to manage interest rate risk is to enter into derivative financial instruments. Derivative financial instruments include interest rate swaps, interest rate caps, floors and collars, futures,

89

Table of Contents

forwards, option contracts and other financial instruments with similar characteristics. Additionally, the Company enters into commitments to fund certain mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of mortgage loans to third party investors. See Note 14 of the Consolidated Financial Statements in Item 1 of this report for further information on the Company’s derivative financial instruments.

During the first three months of 2020, the Company entered into certain covered call option transactions related to certain securities held by the Company. The Company did not enter into such transactions during the first three months of 2021. The Company uses these option transactions (rather than entering into other derivative interest rate contracts, such as interest rate floors) to economically hedge positions and compensate for net interest margin compression by increasing the total return associated with the related securities through fees generated from these options. Although the revenue received from these options is recorded as non-interest income rather than interest income, the increased return attributable to the related securities from these options contributes to the Company’s overall profitability. The Company’s exposure to interest rate risk may be impacted by these transactions. To further mitigate this risk, the Company may acquire fixed rate term debt or use financial derivative instruments. There were no covered call options outstanding as of March 31, 2021 and March 31, 2020.

ITEM 4

CONTROLS AND PROCEDURES

As of the end of the period covered by this report, the Company’s Chief Executive Officer and Chief Financial Officer carried out an evaluation under their supervision, with the participation of other members of management as they deemed appropriate, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as contemplated by Exchange Act Rule 13a-15. Based upon, and as of the date of that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective, in all material respects, in timely alerting them to material information relating to the Company (and its consolidated subsidiaries) required to be included in the periodic reports the Company is required to file and submit to the SEC under the Exchange Act.

There were no changes in the Company’s internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the period that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II —

Item 1: Legal Proceedings

In accordance with applicable accounting principles, the Company establishes an accrued liability for litigation and threatened litigation actions and proceedings when those actions present loss contingencies, which are both probable and estimable. In actions for which a loss is reasonably possible in future periods, the Company determines whether it can estimate a loss or range of possible loss. To determine whether a possible loss is estimable, the Company reviews and evaluates its material litigation on an ongoing basis, in conjunction with any outside counsel handling the matter, in light of potentially relevant factual and legal developments. This review may include information learned through the discovery process, rulings on substantive or dispositive motions, and settlement discussions.

Lehman Holdings Matter

On January 15, 2015, Lehman Brothers Holdings, Inc. ("Lehman Holdings") sent a demand letter asserting that Wintrust Mortgage must indemnify it for losses arising from loans sold by Wintrust Mortgage to Lehman Brothers Bank, FSB under a Loan Purchase Agreement between Wintrust Mortgage, as successor to SGB Corporation, and Lehman Brothers Bank. The demand was the precursor for triggering the alternative dispute resolution process mandated by the U.S. Bankruptcy Court for the Southern District of New York. Lehman Holdings triggered the mandatory alternative dispute resolution process on October 16, 2015. On February 3, 2016, Lehman Holdings filed a complaint against Wintrust Mortgage and 150 other entities from which it had purchased loans in the U.S. Bankruptcy Court for the Southern District of New York. Lehman Holdings filed an amended complaint against Wintrust Mortgage on December 29, 2016. On October 2, 2018, Lehman Holdings asked the court for permission to amend its complaints against Wintrust Mortgage and the other defendants to add loans allegedly purchased from the defendants and sold to various RMBS trusts. The court granted this request and allowed Lehman Holdings to assert the additional claims against existing defendants as a supplemental complaint. Lehman Holdings filed its supplemental complaint against Wintrust Mortgage on December 4, 2018. Wintrust Mortgage filed its response to the supplemental complaint on May 13, 2019. On October 5, 2020, Wintrust Mortgage and Lehman Holdings executed a settlement agreement to resolve the dispute for an amount that is immaterial to the Company's results of operations or financial condition. On October 15, 2020, the court entered an order dismissing the entire suit against Wintrust Mortgage with prejudice.

Wintrust Mortgage Matter

On October 17, 2018, a former Wintrust Mortgage employee filed a lawsuit in the Superior Court of Los Angeles County, California against Wintrust Mortgage alleging violation of California wage payment statutes on behalf of herself and all other hourly, non-exempt employees of Wintrust Mortgage in California. Wintrust Mortgage received service of the complaint on November 4, 2018. Wintrust Mortgage filed its response to the complaint on February 25, 2019. On November 1, 2019, the plaintiff's counsel filed a letter with the California Department of Labor advising that it was initiating an action under California's Private Attorney General Act statute based on the same alleged violations. In November 2019, the parties reached a settlement agreement. The parties executed a settlement agreement and on February 26, 2020, plaintiff moved the court for approval. A hearing on the motion to approve settlement was originally set for June 16, 2020, but the court continued the motion to September 8, 2020. On September 8, 2020, the court requested the parties make certain changes to the settlement agreement that were immaterial to the parties' settlement terms. The parties revised the settlement agreement consistent with the court's recommendations and submitted the revised settlement agreement to the court for its approval. On January 27, 2021, the court entered its preliminary approval of the settlement. Notices of settlement were timely sent to class members who will have until May 2, 2021 to opt out of the settlement. The Company has reserved an amount for this proposed settlement that is immaterial to its results of operations or financial condition.

Northbrook Bank Matter

On October 17, 2018, two individual plaintiffs filed suit in the Circuit Court of Cook County, Illinois against Northbrook Bank and Tamer Moumen on behalf of themselves and a class of approximately 42 investors in a hedge fund run by defendant Moumen. Plaintiffs allege that defendant Moumen ran a fraudulent Ponzi scheme and ran those funds through deposit accounts at Northbrook Bank. They allege the bank was negligent in failing to close the deposit accounts and that it intentionally aided and abetted defendant Moumen in the alleged fraud. They contend that Northbrook Bank is liable for losses in excess of $6 million. Northbrook Bank filed its motion to dismiss the complaint on January 15, 2019, which the court granted on March 5, 2019. On April 3, 2019, the plaintiffs filed an amended complaint based on similar allegations. Northbrook Bank again moved to dismiss. The court heard this motion on July 17, 2019 and once again dismissed the complaint without prejudice. Plaintiffs filed a second amended complaint on August 12, 2019. Northbrook moved to dismiss the second amended complaint. On November 6, 2019, the court dismissed the complaint with prejudice. Plaintiffs filed an appeal on December 2, 2019. After this appeal was fully briefed, on September 4, 2020, the Appellate Court for the First District of Illinois remanded the case back to the trial court for lack of appellate jurisdiction. The Appellate Court determined it did not have jurisdiction to hear the appeal because the trial court did not dismiss the suit against defendant Moumen and plaintiffs did not obtain the trial court's consent for immediate appeal of the dismissal order against Northbrook Bank. On October 29, 2020, the plaintiffs cured the jurisdictional issue identified by the Appellate Court by dismissing defendant Moumen. Plaintiffs filed their renewed appeal on November 4, 2020. This matter has been fully briefed and is awaiting decision by the Appellate Court. Northbrook Bank believes the plaintiffs' allegations are legally and factually meritless and otherwise lacks sufficient information to estimate the amount of any potential liability.

Wintrust Bank Matter

On April 30, 2020, A.D. Sims LLC on behalf of itself and other similarly situated plaintiffs filed suit in the federal district court for the Northern District of Illinois against Wintrust Financial Corporation, Wintrust Bank, N.A., Bank of America, N.A., Cross River Bank, and an additional 4,971 named and unnamed defendants. Plaintiffs allege the defendant financial institutions failed to pay agent fees on loans issued by them under the federal CARES Act's Paycheck Protection Program ("PPP") in violation of applicable law. Plaintiffs allege the collective damages could exceed $3.8 billion and have asked the court to require the defendants to establish, on a pro rata basis, a fund that could be used to pay agent fees due. Plaintiffs voluntarily dismissed Wintrust Financial Corporation as a defendant in this suit on June 29, 2020. On September 28, 2020, the class defendants filed an omnibus motion to dismiss the lawsuit. This motion was fully briefed on November 23, 2020. On December 27, 2020, legislation amending the CARES Act was enacted. The new legislation expressly stated that lenders do not owe fees to agents for assisting borrowers to obtain PPP loans absent a fee agreement between the lender and the agent. In light of this legislation, plaintiff asked the court to dismiss the case. On January 22, 2021, the district court entered plaintiff's voluntary dismissal order.

Other Matters

In addition, the Company and its subsidiaries, from time to time, are subject to pending and threatened legal action and proceedings arising in the ordinary course of business.

Based on information currently available and upon consultation with counsel, management believes that the eventual outcome of any pending or threatened legal actions and proceedings described above, including our ordinary course litigation, will not have a material adverse effect on the operations or financial condition of the Company. However, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to the results of operations or financial condition for a particular period.
