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, 2023 (“2023 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 2023 Form 10-K. In preparation of these financial statements, subsequent events were evaluated through the time the financial statements were issued. Financial statements are considered issued when they are widely distributed to all shareholders and other financial statement users or filed with the SEC.

(2) Recent Accounting Developments

Equity Method and Joint Ventures - Investments in Tax Credit Structures

In March 2023, the FASB issued ASU No. 2023-02, “Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method,” which allows reporting entities the option to apply the proportional amortization method to other tax credit programs besides the Low-Income Housing Tax Credit structures. The guidance requires application of the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing the method at the reporting level entity level. The Company adopted ASU No. 2023-02 as of January 1, 2024. Adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

Segment Reporting

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” to enhance public entity disclosures regarding significant segment expenses which are regularly reported to an entity’s chief operating decision-maker (“CODM”) and included in a segment’s reported profit or loss. This ASU requires disclosure of the amount and composition of “other segment items,” the title and position of the CODM, and how the CODM uses reported measures of profit or loss to assess segment performance. Further, the guidance requires certain segment disclosures previously provided only annually, on an interim basis. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The guidance is to be applied retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements.

6

Income Tax Disclosures

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” to enhance the transparency and decision usefulness of income tax disclosures. This ASU requires annually that all entities disclose increasingly disaggregated information on amount of income taxes paid. Further, this ASU requires annually that all public entities must disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a specific quantitative threshold. This guidance is effective for fiscal years beginning after December 15, 2024, and is to be applied either on a prospective basis or retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of adopting this new guidance on the consolidated financial statements.

Compensation – Scope Application of Profits Interest and Similar Awards

In March 2024, the FASB issued ASU No. 2024-01, “Compensation – Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards” which clarifies the guidance by providing an illustrative example to demonstrate how an entity should apply the scope guidance in Topic 718 when determining whether profits interest and similar awards should be accounted for in accordance with Topic 718. For public business entities, this guidance is effective for fiscal years beginning after December 15, 2024, including interim periods therein, and is to be applied either on a prospective basis or retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of adopting this new guidance on the consolidated financial statements.

(3) Business Combinations

On August 1, 2024, the Company completed its previously announced acquisition of Macatawa Bank Corporation (“Macatawa”), the parent company of Macatawa Bank. Pursuant to the terms of the merger, each common share of Macatawa outstanding at the time of merger was converted into the right to receive 0.137 shares of Wintrust common stock, with cash paid in lieu of fractional shares. As a result, the Company issued approximately 4.7 million shares of common stock, the fair value of consideration paid was $ 499.3 million. Macatawa operates 26 full-service branches located throughout communities in Kent, Ottawa and northern Allegan counties in the state of Michigan. Macatawa offers a full range of banking, retail and commercial lending, wealth management and ecommerce services to individuals, businesses and governmental entities. As of August 1, 2024, Macatawa had approximately $ 2.7 billion in assets, $ 2.3 billion in deposits and $ 1.3 billion in loans. In conjunction with the acquisition, the Company recorded $ 53.7 million discount on acquired loans, $ 33.5 million discount on securities and recorded total intangibles of $ 251.9 million. During the three and nine months ended September 30, 2024, the Company incurred $ 1.6 million and $ 2.5 million, respectively, in acquisition expenses related to the acquisition of Macatawa. The initial purchase accounting for the acquisition, in accordance with GAAP, for this business combination is not finalized and is therefore subject to change.

On April 3, 2023, the Company completed its acquisition of Rothschild & Co Asset Management US Inc. and Rothschild & Co Risk Based Investments LLC from Rothschild & Co North America Inc. As of the acquisition date, the Company acquired approximately $ 12.6 million in net assets. As the transaction was determined to be a business combination, the Company recorded goodwill of approximately $ 2.6 million on the purchase.

(4) 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.

Equity securities without readily determinable fair values totaled $ 64.1 million as of September 30, 2024. Equity securities without readily determinable fair values are included as part of accrued interest receivable and other assets in the Company’s Consolidated Statements of Condition. The Company monitors its equity investments without readily determinable fair values 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. During the three and nine months ended September 30, 2024 and September 30, 2023, the Company recorded no upward or downward adjustments related to such observable price changes. 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 September 30, 2024, the Company recorded no impairment of equity securities without readily determinable fair values. During the nine months ended September 30, 2024, the Company recorded $ 3.7 million of impairment of equity securities without readily determinable fair values. During the three and nine months ended September 30, 2023, the Company recorded $ 489,000 impairment of equity securities without readily determinable fair values.

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 September 30, 2024 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 at September 30, 2024 were primarily mortgage-backed securities with unrealized losses due to increased market rates during such period.

See Note (7) “Allowance for Credit Losses” in Item 1 of this report for further discussion regarding any credit losses associated with held-to-maturity securities at September 30, 2024.

Various niche lending businesses, including franchise lending and insurance agency lending, operate on a national level. 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 $ 266.1 million at September 30, 2024, $ 285.4 million at December 31, 2023 and $ 264.5 million at September 30, 2023.

Total loans, excluding purchased credit deteriorated (“PCD”) loans, include net deferred loan fees and costs and fair value purchase accounting adjustments totaling $ 79.4 million at September 30, 2024, $ 84.2 million at December 31, 2023 and $ 67.6 million at September 30, 2023.

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.

(7) Allowance for Credit Losses

In accordance with Accounting Standards Codification (“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 assets held at amortized cost, specifically the Company's loan portfolio and debt securities classified as held-to-maturity. Descriptions of the Company’s loan portfolio segments and major debt security types are included in Note (5) “Allowance for Credit Losses” of the 2023 Form 10-K.

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 $ 351.5 million at September 30, 2024, $ 304.5 million at December 31, 2023, and $ 290.9 million at September 30, 2023.

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
16

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 considered when the expected extension, renewal or modification is contained within the existing agreement and is not unconditionally cancelable. 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. 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 September 30, 2024, excluding loans carried at fair value, substandard nonaccrual loans totaling $ 62.7 million in carrying balance had no related allowance for credit losses.

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.

For the three and nine months ended September 30, 2024, the Company recognized approximately $ 22.3 million and $ 83.9 million of provision for credit losses, respectively, related to loans and lending agreements, which includes $ 15.5 million of Day 1 provision related to the acquisition of Macatawa. The provision for each period was primarily the result of losses experienced in the Commercial, Commercial Real Estate and Premium Finance Receivables portfolios along with growth across various segments, which was offset by improved macroeconomic forecasts related to Baa Credit Spread and CRE Price Index. Uncertainties remain regarding expected economic performance and macroeconomic forecasts utilized in the measurement of the allowance for credit losses as of September 30, 2024. Net charge-offs in the three and nine month periods ended September 30, 2024, totaled $ 26.7 million and $ 78.5 million, respectively.

Held-to-maturity debt securities

The allowance for credit losses on the Company’s held-to-maturity debt securities is presented as a reduction to the amortized cost basis of held-to-maturity securities on the Company's Consolidated Statements of Condition. For the three and nine month
19

period ended September 30, 2024, the Company recognized approximately $( 12,000 ) and $ 132,000 , respectively, of provision for credit losses related to held-to-maturity securities. At September 30, 2024, the Company did not identify any held-to-maturity debt securities within its portfolio that would require a charge-off.

Loan Modifications to Borrowers Experiencing Financial Difficulties

The Company’s approach to restructuring or modifying 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 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. 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.

Restructurings 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 other real estate owned (“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 September 30, 2024, the Company had no foreclosed residential real estate properties included within OREO. Further, the recorded investment in residential mortgage loans secured by residential real estate properties for which foreclosure proceedings are in process totaled $ 40.4 million and $ 55.1 million at September 30, 2024 and 2023, respectively.

The tables below presents a summary of the period-end balance of loans to borrowers experiencing financial difficulties during the three and nine months ended September 30, 2024 and 2023:

(8) Goodwill and Other Acquisition-Related Intangible Assets

A summary of the Company’s goodwill assets by reporting unit is presented in the following table:
(In thousands) December 31, 2023 Goodwill
Acquired

Goodwill Adjustments September 30,
2024
Community banking $ 545,671 $ 144,586 $ $ $ 690,257
Specialty finance 39,006 ( 478 ) 38,528
Wealth management 71,995 71,995
Total $ 656,672 $ 144,586 $ $ ( 478 ) $ 800,780

The community banking unit's goodwill increased $ 144.6 million in the third quarter of 2024 as a result of the Macatawa acquisition. The specialty finance unit’s goodwill decreased $ 478,000 in the first nine months of 2024 as a result of foreign currency translation adjustments related to the Canadian acquisitions.

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, 2023, the Company utilized a qualitative approach for its annual goodwill impairment tests of the community banking, specialty finance and wealth
23

management reporting units and determined that it was more likely than not that the fair value of all reporting units exceeded the respective carrying value of such reporting unit at that time.

At each reporting date between annual goodwill impairment tests, the Company considers potential indicators of impairment. The Company assessed whether 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. Potential 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.

At the conclusion of this assessment of all reporting units, the Company determined that as of September 30, 2024, it was more likely than not that the fair value of all reporting units exceeded the respective carrying value of such reporting unit.

A summary of acquisition-related intangible assets as of the dates shown and the expected amortization of finite-lived acquisition-related intangible assets as of September 30, 2024 is as follows:

The community banking unit's core deposit intangibles and trademarks with indefinite lives increased $ 99.3 million and $ 8.0 million, respectively, in the third quarter of 2024 as a result of the Macatawa acquisition.

The core deposit intangibles recognized in connection with the Company’s bank acquisitions are amortized over a ten-year period on an accelerated basis. The customer list intangibles recognized in connection with the purchase of life insurance premium finance assets in 2009 are being amortized over an 18-year period on an accelerated basis. The customer list and other
24

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 or accelerated basis. Indefinite-lived intangible assets consist of certain trade and domain names recognized in connection with prior acquisitions. 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 acquisition-related intangibles totaled approximately $ 6.3 million and $ 4.1 million for the nine months ended September 30, 2024 and 2023, respectively.

(9) Mortgage Servicing Rights (“MSRs”)

The following is a summary of the changes in the carrying value of MSRs, accounted for at fair value, for the periods indicated:

Fair value at end of the period $ 186,308 $ 210,524 $ 186,308 $ 210,524
Unpaid principal balance of mortgage loans serviced for others $ 12,253,361 $ 11,885,531

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. MSRs are included in other assets in the Consolidated Statements of Condition. 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 early buyout options (“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.

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.

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 not to 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 MSRs. The gain or loss associated with these derivative contracts is included in mortgage banking revenue. For more information regarding these hedges outstanding as of September 30, 2024 and September 30, 2023, see Note (14) “Derivative Financial Instruments” in Item 1 of this report.

Short-term Borrowings

Short-term borrowings include securities sold under repurchase agreements of customer sweep accounts in connection with master repurchase agreement at the banks. There were no borrowings at September 30, 2024 compared to $ 13.4 million and $ 14.2 million at December 31, 2023 and September 30, 2023, respectively. As of September 30, 2024, the Company had no pledged securities related to its customer balances in sweep accounts.

Secured Borrowings

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”). On August 29, 2024, the Company entered into the Twelfth Amending Agreement to the Receivables Purchase Agreement dated as of December 16, 2014. The amended Receivables Purchase Agreement provides for, among other things, an extension of the maturity date to December 15, 2025 and an increase to the facility limit from $ 520 million to $ 650 million. Additionally, Wintrust guarantees the performance of FIFC Canada of its obligations under the Receivables Purchase Agreement and any subsequent amendments thereto.

At September 30, 2024, the translated balance of the secured borrowings totaled $ 428.6 million compared to $ 392.5 million at December 31, 2023 and $ 382.8 million at September 30, 2023. The interest rate under the Receivables Purchase Agreement is the Canadian Commercial Paper Rate plus fee rate of 0.825 %.

The remaining $ 10.9 million, $ 9.4 million and $ 8.9 million within secured borrowings at September 30, 2024, December 31, 2023 and September 30, 2023, respectively, represent 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.

Other Borrowings

Other borrowings represent a fixed-rate promissory note (“Fixed-Rate Promissory Note”) issued by the Company in June 2017. Subsequent amendments to the Fixed-Rate Promissory Note since issuance increased the principal amount to $ 66.4 million, reduced the interest rate to 1.70 % and extended the maturity date to March 31, 2025. The Fixed-Rate Promissory Note contains several restrictive covenants, including the maintenance of various capital adequacy levels, asset quality and profitability ratios, and certain restrictions on dividends and indebtedness. At September 30, 2024, the Company was in compliance with all such covenants.

Subordinated Notes

At September 30, 2024, the Company had outstanding subordinated notes totaling $ 298.2 million compared to $ 437.9 million and $ 437.7 million at December 31, 2023 and September 30, 2023, respectively. The notes issued in 2019 have a stated interest rate of 4.85 % and mature in June 2029. In the second quarter of 2024, the Company repaid the $ 140.0 million of subordinated notes issued in 2014. The notes had a stated interest rate of 5.00 % and matured in June 2024.

(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 sixteen 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 (10) “Deposits” in Item 1 of this report 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 Note (1) “Summary of Significant Accounting Policies” of the 2023 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 or commodity price) 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 fair value adjustments related to the Company’s mortgage servicing rights portfolio. The Company also enters into derivatives (typically interest rate swaps and commodity forward contracts) 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.

30

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. Commodity derivative fair values are computed based on changes in the price per unit 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 September 30, 2024, December 31, 2023 and September 30, 2023:

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 and interest rate collars as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts to or from a counterparty in exchange for the Company receiving or paying 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 settlement of amounts in which the interest rate index specified in the contract exceeds the agreed upon cap strike rate or in which the interest rate index specified in the contract is below the agreed upon floor strike rate at the end of each period.

As of September 30, 2024, the Company had various interest rate collar and swap derivatives designated as cash flow hedges of variable rate loans. 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 income as interest payments
31

are made on such variable rate loans. 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 September 30, 2024:

Total Cash Flow Hedges $ 6,700,000 $ 38,880

In the first quarter of 2022, the Company terminated interest rate swap derivative contracts designated as cash flow hedges of variable rate deposits with a total notional value of $ 1.0 billion and a five-year term effective July 2022. At the time of termination, the fair value of the derivative contracts totaled an asset of $ 66.5 million, with such adjustments to fair value recorded in accumulated other comprehensive income or loss. In the second quarter of 2022, the Company terminated two additional interest rate swap derivative contracts designated as cash flow hedges of variable rate deposits with a total notional value of $ 500.0 million each effective since April 2020. The remaining terms of such derivative contracts were through March 2023 and April 2024 and, at the time of termination, the fair value of the derivative contracts totaled assets of $ 3.7 million and $ 10.7 million, respectively, with such adjustments to fair value recorded in accumulated other comprehensive income or loss. In the fourth quarter of 2022, the Company terminated one additional interest rate collar derivative contract designated as a cash flow hedge of a term borrowing facility with a total notional value of $ 64.3 million effective since September 2018. The remaining term of such derivative contract was through September 2023 and, at the time of termination, the fair value of the derivative contract totaled an asset of $ 875,000 , with such adjustments to fair value recorded in accumulated other comprehensive income or loss.

For all such terminations, as the hedged forecasted transactions (interest payments on variable rate deposits and a term borrowing facility) are still expected to occur over the remaining term of such terminated derivatives, such adjustments will remain in accumulated other comprehensive income or loss and be reclassified as a reduction to interest expense on a straight-line basis over the original term of the terminated derivative contracts.

Unrealized gain (loss) at end of period $ 75,452 $ ( 104,821 ) $ 75,452 $ ( 104,821 )

As of September 30, 2024, the Company estimated that during the next 12 months $ 13.9 million will be reclassified from accumulated other comprehensive income or loss as a decrease to net interest income. Such estimate consists of $ 13.3 million reclassified as a reduction to interest expense on the terminated cash flow hedges discussed above and $ 27.2 million reclassified as a reduction to interest income related to the interest rate collars and swaps noted above that remain outstanding.

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 September 30, 2024, the Company had 13 interest rate swaps with an aggregate notional amount of $ 204.3 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.

The following table presents the carrying amount of the hedged assets/(liabilities) and the cumulative amount of fair value hedging adjustment included in the carrying amount of the hedged assets/(liabilities) that are designated as a fair value hedge accounting relationship as of September 30, 2024:

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
33

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. As of September 30, 2024, there were no interest rate caps outstanding that were designed to act as an economic hedge.

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 September 30, 2024 and December 31, 2023, the Company had interest rate derivative transactions with an aggregate notional amount of approximately $ 12.8 billion and $ 11.4 billion, respectively, (all interest rate swaps and caps with customers and third parties) related to this program. At September 30, 2024 these interest rate derivatives had maturity dates ranging from October 2024 to January 2037.

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 its 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 September 30, 2024 and December 31, 2023, the Company had interest rate lock commitments with an aggregate notional amount of approximately $ 288.9 million and $ 129.9 million, and forward commitments to sell mortgage loans with an aggregate notional amount of approximately $ 667.6 million and $ 626.9 million, respectively. The fair values of these derivatives were 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.

Commodity Derivatives— The Company has commodity forward contracts resulting from a service the Company provides to certain qualified borrowers. The Company’s banking subsidiaries execute certain derivative products directly with qualified commercial borrowers to facilitate their respective risk management strategies. For example, these arrangements allow the Company’s commercial borrowers to effectively purchase or sell a given commodity at an agreed-upon price on an agreed-upon settlement date. 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 September 30, 2024 and December 31, 2023, the Company had commodity derivative transactions with an aggregate notional amount of approximately $ 7.6 million and $ 8.4 million, respectively, (all forward contracts with customers and third parties) related to this program. At September 30, 2024, these commodity derivatives had maturity dates ranging from October 2024 to October 2025.

Foreign Currency Derivatives— The Company has foreign currency derivative contracts resulting from a service the Company provides to certain qualified customers. The Company’s banking subsidiaries execute certain derivative products directly with qualified customers to facilitate their respective risk management strategies related to foreign currency fluctuations. For example, these arrangements allow the Company’s customers to effectively exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date. 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. As of September 30, 2024 and December 31, 2023, the Company held foreign currency derivatives with an aggregate notional amount of approximately $ 108.9 million and $ 144.3 million, respectively.
34

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 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 the fair value of these contracts are recognized as other non-interest income. There were no covered call options outstanding as of September 30, 2024, December 31, 2023 or September 30, 2023.

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. The Company held eight interest rate derivatives with an aggregate notional value of $ 220.0 million at September 30, 2024 and four interest rate derivatives with an aggregate notional value of and $ 195.0 million at December 31, 2023, for such purpose of economically hedging a portion of the fair value adjustment related to its mortgage servicing rights portfolio.

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 September 30, 2024, there were $ 97.5 million interest rate derivatives in a net asset position that were subject to such agreements. The fair value of such derivatives includes accrued interest related to these agreements. If the Company had breached any of these provisions and those derivatives subject to such agreements were in a liability position, 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 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.

(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 determine the fair value of 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 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 September 30, 2024, the Company classified $ 135.3 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’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 third quarter of 2024, 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 September 30, 2024 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.

Mortgage loans held-for-sale —The fair value of mortgage loans held-for-sale is typically determined by reference to investor price sheets for loan products with similar characteristics. Loans measured with this valuation technique are classified as Level 2 in the fair value hierarchy.

At September 30, 2024, the Company classified $ 59.1 million of certain delinquent mortgage loans held-for-sale as Level 3. For such delinquent loans in which investor interest may be limited, the Company estimates fair value by discounting future scheduled cash flows for the specific loan through its life, adjusted for estimated credit losses. The Company uses a discount rate based on prevailing market coupon rates on loans with similar characteristics. The assumed weighted average discount rate used as an input to value these loans at September 30, 2024 was 6.14 %. The higher the rate utilized to discount estimated future cash flows, the lower the fair value measurement. Additionally, the weighted average credit discount used as an input to value the specific loans was 0.52 % with credit loss discount ranging from 0 %- 14 % at September 30, 2024.

Loans held-for-investment —The fair value for certain loans in which the Company previously 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 prepayment or life assumptions. These loans primarily consist of early buyout loans guaranteed by U.S. government agencies that are delinquent and, as a result, investor interest may be limited. The Company uses a discount rate based on the actual coupon rate of the underlying loan. At September 30, 2024, the Company classified $ 44.8 million of loans held-for-investment carried at fair value as Level 3. The assumed weighted average discount rate used as an input to value these loans at September 30, 2024 was 6.14 %. 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 average life as well as credit losses. The weighted average prepayments speed used as an input to value current loans was 9.21 % at September 30, 2024. Prepayment speeds are inversely related to the fair value of these loans as an increase in prepayment speeds results in a decreased valuation. For delinquent loans in which performance is not assumed and there is a higher probability of resolution of the loan ending in foreclosure, the weighted average life of such loans was 5.9 years. Average life is inversely related to the fair value of these loans as an increase in estimated life results in a decreased valuation. Additionally, the weighted average credit discount used as an input to value the specific loans was 1.07 % with credit loss discounts ranging from 0 %- 39 % at September 30, 2024.

MSRs —Fair value for MSRs is determined utilizing a valuation model which calculates the fair value of each servicing right based on the present value of estimated future cash flows. The Company uses a discount rate commensurate with the risk associated with each servicing right, given current market conditions. At September 30, 2024, the Company classified $ 186.3 million of MSRs as Level 3. The weighted average discount rate used as an input to value the pool of MSRs at September 30, 2024 was 10.96 % with discount rates applied ranging from 6 %- 20 %. 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 %- 90 % or a weighted average prepayment speed of 9.21 %. Further, for current and delinquent loans, the Company assumed a weighted average cost of servicing of $ 76 and $ 386 , 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 (9) “Mortgage Servicing Rights (“MSRs”)” in Item 1 of this report for further discussion of MSRs.

37

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 mortgage loans, commodity future contracts and foreign currency contracts. Interest rate swaps, caps and collars and commodity future contracts are valued by a third party, using models that primarily use market observable inputs, such as yield curves and commodity prices prevailing at the measurement date, 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 September 30, 2024, the Company classified $ 5.1 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 September 30, 2024 was 80.71 % with pull-through rates applied ranging from 1 % 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 September 30, 2024, December 31, 2023 and September 30, 2023 for mortgage loans held-for-sale measured at fair value under ASC 825 was $ 462.2 million, $ 291.7 million and $ 308.5 million, respectively, while the aggregate fair value of mortgage loans held-for-sale was $ 461.1 million, $ 292.7 million and $ 304.8 million, for the same respective periods, as shown in the above tables. At September 30, 2024, $ 2.4 million of mortgage loans held-for-sale were classified as nonaccrual compared to $ 649,000 as of December 31, 2023 and $ 619,000 as of September 30, 2023. Additionally, there were $ 58.4 million of loans past due greater than 90 days and still accruing in the mortgage loans held-for-sale portfolio as of September 30, 2024 compared to $ 26.6 million as of December 31, 2023 and $ 23.7 million as of September 30, 2023. All of the nonaccrual loans and loans past due greater than 90 days and still accruing within the mortgage loans held-for-sale portfolio at September 30, 2024, December 31, 2023, and September 30, 2023 were individual delinquent mortgage loans bought back from GNMA at the unconditional option of the Company as servicer for those loans.

The aggregate remaining contractual principal balance outstanding as of September 30, 2024, December 31, 2023 and September 30, 2023 for loans held-for-investment measured at fair value under ASC 825 was $ 138.8 million, $ 156.9 million and $ 171.9 million, respectively, while the aggregate fair value of loans held-for-investment was $ 138.0 million, $ 155.3 million and $ 171.2 million, respectively, as shown in the above tables.

(1) Changes in the balance of mortgage loans held-for-sale, MSRs and derivative assets related to fair value adjustments are recorded as components of mortgage banking revenue. Changes in the balance of loans held-for-investment related to fair value adjustments are recorded as other non-interest income.

Also, the Company may be required, from time to time, to measure certain other assets at fair value on a non-recurring 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 non-recurring 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 September 30, 2024:

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 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 (7) “Allowance for Credit Losses” in Item 1 of this report. At September 30, 2024, the Company had $ 124.6 million of individually assessed loans classified as Level 3. All of the $ 124.6 million of individually assessed loans were measured at fair value based on the underlying collateral of the loan as shown in the table above.

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 September 30, 2024, the Company had $ 13.7 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 September 30, 2024 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, municipal bonds issued by various municipal government entities primarily located in the Chicago metropolitan area and southern Wisconsin and mortgage-backed securities. 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). The fair value for 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 category. In accordance with ASC 820, the Company has categorized these loans as a Level 3 fair value measurement.

43

Time certificates of deposit. The fair value of time 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 time certificates of deposit. In accordance with ASC 820, the Company has categorized time certificates of deposit as a Level 3 fair value measurement.

FHLB advances. The fair value of FHLB advances is estimated by 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

As of September 30, 2024, approximately 659,000 shares were available for future grants, assuming the maximum number of shares are issued for the performance awards outstanding, approved under the Company Stock Incentive Plans (“the Plans”). Descriptions of the Plans are included in Note (18) “Stock Compensation Plans and Other Employee Benefit Plans” of the 2023 Form 10-K.

Stock-based compensation expense recognized in the Consolidated Statements of Income was $ 9.5 million in the third quarter of 2024 and $ 8.1 million in the third quarter of 2023, and $ 27.6 million and $ 24.5 million in the nine months ended September 30, 2024 and 2023, respectively.

(2) Aggregate intrinsic value represents the total pre-tax intrinsic value (i.e., the difference between the Company’s stock price on the last trading day of the quarter and the option exercise price, multiplied by the number of shares) that would have been received by the option holders if they had exercised their options on the last day of the quarter. Options with exercise prices above the stock price on the last trading day of the quarter are excluded from the calculation of intrinsic value. The intrinsic value will change based on the fair market value of the Company’s stock.

The aggregate intrinsic value of options exercised during the nine months ended September 30, 2024 and September 30, 2023, was approximately $ 50,000 and $ 2.5 million, respectively. Cash received from option exercises under the Plans for the nine months ended September 30, 2024 and September 30, 2023 was approximately $ 25,000 and $ 2.2 million, respectively.

Potentially dilutive common shares can result from stock options, restricted stock unit awards and shares to be issued under the Employee Stock Purchase Plan and the Directors Deferred Fee and Stock Plan, being treated as if they had been either exercised or issued, computed by application of the treasury stock method. While potentially dilutive common shares are typically included in the computation of diluted earnings per share, potentially dilutive common shares are excluded from this computation in periods in which the effect of inclusion would either reduce the loss per share or increase the income per share.

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 September 30, 2024 compared with December 31, 2023 and September 30, 2023, and the results of operations for the three and nine month periods ended September 30, 2024 and September 30, 2023, 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, 2023 (“2023 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 and commercial banking services and offers a full array of wealth management services, primarily to customers 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.

Overview

Third Quarter Highlights

The Company recorded net income of $170.0 million for the third quarter of 2024 compared to $164.2 million in the third quarter of 2023. The results for the third quarter of 2024 demonstrate the Company's ability to grow net interest income through both organic earning asset growth and growth through acquisitions. Partially offsetting the increase in net interest income was an increase in non-interest expense. The increase in non-interest expense was a result of additional expenses to support organic growth as well as the impact from the Macatawa acquisition. Comprehensive income includes 1) net income as presented on the Company’s Consolidated Statements of Income and 2) other comprehensive income or loss from unrealized gains and losses on the Company’s available-for-sale investment securities portfolios and derivative contracts designated as cash flow hedges as well as foreign currency translation adjustments. Comprehensive income (loss) totaled $390.0 million for the third quarter of 2024 compared to a loss of $4.4 million for the third quarter of 2023.

The Company increased its loan portfolio from $41.4 billion at September 30, 2023 and $42.1 billion at December 31, 2023 to $47.1 billion at September 30, 2024. The increase in the current period compared to the prior periods was a result of organic growth in several portfolios, including the commercial, commercial real estate, residential real estate loans held for investment portfolios, and property and casualty insurance premium finance receivable portfolios as well as $1.3 billion in loans acquired from Macatawa. For more information regarding changes in the Company’s loan portfolio, see Financial Condition – Interest Earning Assets and Note (6) “Loans” of the Consolidated Financial Statements in Item 1 of this report.

The Company recorded net interest income of $502.6 million in the third quarter of 2024 compared to $462.4 million in the third quarter of 2023. This increase in net interest income recorded in the third quarter of 2024 compared to the third quarter of 2023 resulted primarily from growth in earning assets, specifically a $5.2 billion increase in average loans. Net interest margin was 3.49% (3.51% on a fully taxable-equivalent basis, non-GAAP) in the third quarter of 2024 compared to 3.60% (3.62% on a fully taxable-equivalent basis, non-GAAP) in the third quarter of 2023. The decrease is primarily due to higher rates on interest-bearing liabilities, most notably interest-bearing deposits (see “Net Interest Income” for further detail).

Non-interest income totaled $113.1 million in the third quarter of 2024 compared to $112.5 million in the third quarter of 2023. The increase is due to increased net gains on investment securities of $5.5 million, increased wealth management revenue of $3.7 million and an increase of service charges on deposits of $2.2 million which was offset by decreased mortgage banking revenue of $11.4 million in the third quarter of 2024 compared to the third quarter of 2023 (see “Non-Interest Income” for further detail).

Non-interest expense totaled $360.7 million in the third quarter of 2024, an increase of $30.6 million, or 9%, compared to the third quarter of 2023. This increase compared to the third quarter of 2023 was primarily attributable to increased salaries and employee benefits of $18.9 million and increased software and equipment expenses of $5.6 million. (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 third quarter of 2024, 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. See “Deposits” and “Other Funding Sources” for additional information regarding liquidity sources.

(1) See following section titled “Supplemental Non-GAAP Financial Measures/Ratios” for additional information on this performance measure/ratio.
(2) Net revenue is net interest income plus non-interest income.
(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%.

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 (“FTE”) basis. In this non-GAAP presentation, net interest income is adjusted to reflect tax-exempt interest income on an equivalent before-tax basis using tax rates effective as of the end of the period. This measure ensures comparability of net interest income arising from both taxable and tax-exempt sources. Net interest income on a fully taxable-equivalent basis is also used in the calculation of the Company’s efficiency ratio. The efficiency ratio, which is calculated by dividing non-interest expense by total taxable-equivalent net revenue (less securities gains or losses), measures how much it costs to produce one dollar of revenue. Securities gains or losses are excluded from this calculation to better match revenue from daily operations to operational expenses. Management considers the tangible common equity ratio and tangible book value per common share as useful measurements of the Company’s equity. The Company references the return on average tangible common equity as a measurement of profitability. Management considers pre-tax income, excluding provision for credit losses as a useful measurement of the Company’s core net income.

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

Critical Accounting Estimates

The Company’s Consolidated Financial Statements are prepared in accordance with GAAP in the United States, prevailing practices of the banking industry, and the application of accounting policies of which are described in Note (1) “Summary of Significant Accounting Policies” to the Consolidated Financial Statements in Item 8 of the Company’s 2023 Form 10-K. These policies require numerous estimates and strategic or economic assumptions, which may prove inaccurate or subject to
51

variations. Changes in underlying factors, assumptions or estimates could have a material impact on the Company’s future financial condition and results of operations. At September 30, 2024, management views critical accounting estimates to include the determination of the allowance for credit 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 most subject to revision as new information becomes available. These estimates were reviewed with the Audit Committee of the Board of Directors.

Allowance for Credit Losses, including the Allowance for Loan Losses, Allowance for Losses on Lending-Related Commitments and Allowance for Held-to-Maturity Debt Securities

The allowance for credit losses represents management’s estimate of expected credit losses over the life of a financial asset carried at amortized cost. Determining the amount of the allowance for credit losses is considered a critical accounting estimate because it requires significant judgment and the use of estimates related to the fair value of the underlying collateral and amount and timing of expected future cash flows on individually assessed financial assets, estimated credit losses on pools of loans with similar risk characteristics, and consideration of reasonable and supportable forecasts of macroeconomic conditions, all of which are susceptible to significant change. At September 30, 2024, the loan and held-to-maturity debt securities portfolios represent 80% of the total assets on the Company’s consolidated balance sheet. The Company also maintains an allowance for lending-related commitments, specifically unfunded loan commitments and letters of credit, which relates to certain amounts the Company is committed to lend (not unconditionally cancelable) but for which funds have not yet been disbursed.

Key macroeconomic variable data points that are significant inputs into our credit loss models for the commercial and commercial real estate portfolios are the Baa corporate credit spread as well as CREPI specifically related to the commercial real estate portfolio. Holding all other inputs constant, the table below shows the impact of changes in these key macroeconomic variable data points on the estimate of allowance for credit losses.

Impact to estimated allowance for credit losses from an increased or higher input value
Baa Credit Spread Increases
CRE Price Index Decreases

Holding all other inputs constant, the following table provides a sensitivity analysis for the commercial and commercial real estate portfolios based on a 20 basis point change in Baa credit spreads from the assumption utilized in the estimate of that portfolio’s allowance for credit losses at September 30, 2024:

Baa Credit Spread
Narrows Widens
Commercial Decreases estimate by 5%-10% Increases estimate by 10%-15%
Commercial Real Estate:
Construction Decreases estimate by 15%-20% Increases estimate by 15%-20%
Non-Construction Decreases estimate by 5%-6% Increases estimate by 5%-6%

Holding all other inputs constant, the following table provides a sensitivity analysis for the commercial real estate construction and non-construction portfolios based on a 10% change in CREPI from the assumption utilized in the estimate of that portfolio’s allowance for credit losses at September 30, 2024:

CRE Price Index
Increases Decreases
Commercial Real Estate:
Construction Decreases estimate by 40%-45% Increases estimate by 105%-110%
Non-Construction Decreases estimate by 30%-35% Increases estimate by 55%-60%

See Note (7) “Allowance for Credit Losses” to the Consolidated Financial Statements in Item 1 of this report and the section titled “Credit Quality” in Item 2 of this report for a description of the methodology used to determine the allowance for credit losses.

For a more detailed discussion on these critical accounting estimates, see “Summary of Critical Accounting Estimates” beginning on page 57 of the 2023 Form 10-K.

Net Income

Net income for the quarter ended September 30, 2024 totaled $170.0 million, an increase of $5.8 million, or 4%, compared to the quarter ended September 30, 2023. On a per share basis, net income for the third quarter of 2024 totaled $2.47 per diluted common share compared to $2.53 for the third quarter of 2023.

The increase in net income for the third quarter of 2024 as compared to the same period in the prior year is primarily attributable to increased net interest income, partially offset by increased non-interest expense including the impact of the Macatawa acquisition. See “Net Interest Income”, “Non-interest Income”, “Non-interest Expense” and “Credit 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.

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

Wealth management revenue increased by $3.7 million and $10.1 million in the three and nine months ended September 30, 2024 as compared to the same periods of 2023, respectively. For the three and nine months ended September 30, 2024, the increase is primarily due to increased asset management fees as a result of higher assets under management when compared to same period in the prior year.

Mortgage banking revenue decreased for the three months ended September 30, 2024 as compared to the same period in 2023 due to lower net revenue related to MSR activity and valuation adjustments. On a year-to-date basis, mortgage banking revenue decreased slightly for the nine months ended September 30, 2024 as compared to the same period in 2023 as a result of lower net revenue related to MSR activity which was offset by higher production revenue from increased mortgage production. Mortgage banking revenue includes revenue from activities related to originating, selling and servicing residential real estate loans for the secondary market. A main factor in the mortgage banking revenue recognized by the Company is the volume of mortgage loans originated or purchased for sale. Mortgage loans originated for sale totaled $766.8 million in the third quarter of 2024 as compared to $572.6 million in the third quarter of 2023. On a year-to-date basis, mortgage loans originated for sale totaled $2.0 billion for the nine months ended September 30, 2024 as compared to $1.5 billion for the nine months ended September 30, 2023. The increase in originations from the comparative three and nine month periods was driven by growth in both purchase and refinance originations as housing inventories have improved and interest rates pulled back from peak levels reached in 2023. The percentage of origination volume from refinancing activities was 28% and 22% for the three and nine months ended September 30, 2024, as compared to 16% and 17%, for the same periods in 2023, respectively.

The Company records MSRs at fair value on a recurring basis. For the three months ended September 30, 2024, the fair value of the MSRs portfolio decreased as a result of an unfavorable fair value adjustment of $17.3 million was recorded and a reduction in value of $7.3 million due to payoffs, paydowns and repurchases of the existing portfolio, partially offset as r etained servicing rights led to capitalization of $6.4 million. On a year-to-date basis, the fair value of MSRs decreased due to a unfavorable fair value adjustment of $8.9 million as well as a reduction in value of $17.2 million due to payoffs, paydowns and repurchases of the existing portfolio, partially offset by retained servicing rights led to capitalization of $20.0 million. See Note (9) “Mortgage Servicing Rights (“MSRs”)” to the Consolidated Financial Statements in Item 1 of this report for a summary of the changes in the carrying value of MSRs.

57

Mortgage banking revenue is also impacted by changes in the fair value of derivative contracts held to economically hedge a portion of the fair value adjustments related to the Company’s MSRs portfolio. The change in fair value of the derivative contracts held as an economic hedge was a favorable $6.9 million and $3.5 million for the three and nine months ended September 30, 2024, respectively.

Service charges on deposits increased for the three and nine months ended September 30, 2024 as compared to the same periods in 2023 primarily as a result of increased account analysis services fees. 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.

The Company recognized net gains on investment securities for the three and nine months ended September 30, 2024 of $3.2 million and $233,000, respectively. The Company recognized net losses on investment securities for the three and nine months ended September 30, 2023 of $2.4 million and $1.0 million, respectively. The net gains for the three and nine months ended September 30, 2024 were primarily due to gains on the Company’s equity investment securities recorded in the third quarter of 2024. See Note (5) “Investment Securities” to the Consolidated Financial Statements in Item 1 of this report for more information on net gains and losses on investment securities.

Fees from covered call options for the three and nine months ended September 30, 2024 decreased $3.2 million and $9.3 million, respectively, when compared to the same periods in the prior year, respectively. The decreased income was primarily because the Company sold less options than the prior year for both comparative periods. The Company has typically written call options with terms of less than three months against certain U.S. Treasury and agency securities held in its portfolio for liquidity and other purposes. Management has effectively entered into these transactions with the goal of economically hedging security positions and enhancing its overall return on its investment portfolio. These option transactions are designed to increase the total return associated with holding certain investment securities and do not qualify as hedges pursuant to accounting guidance. There were no outstanding call option contracts at September 30, 2024 and 2023.

Miscellaneous non-interest income includes loan servicing fees, income from other investments, and other fees. This category of income increased $277,000 and $30.9 million for the three and nine months ended September 30, 2024 compared to the same periods in 2023, respectively. For the three months ended September 30, 2024, miscellaneous income increased compared to the same period in 2023 primarily due higher fee income earned on card-related arrangements and partnership income. The increased income on a year-to-date basis was primarily due to a $20.0 million gain recognized in the first quarter of 2024 related to the sale of the Company’s Retirement Benefits Advisors (“RBA") division within its wealth management business as well as a $4.6 million gain recognized in the second quarter of 2024 on the sale of premium finance receivables.

Notable contributions to the change in non-interest expense are as follows:
Salaries and employee benefits expense increased for the three and nine months ended September 30, 2024 as compared to the same periods in 2023. The increase was primarily due to elevated commissions from increased mortgage production as well as due to the increase in employees related to the growth of the Company, including the Macatawa acquisition.
Software and equipment expense increased for the three and nine months ended September 30, 2024 as compared to the same periods in 2023 as a result of higher software license fees as well as higher computer and software depreciation expense as the Company invests in enhancements to the digital customer experience, upgrades to infrastructure and enhancements to information security capabilities.
Amortization of other acquisition-related intangible assets increased for the three and nine months ended September 30, 2024 compared to the same periods in 2023. The Macatawa acquisition impacted this increase by approximately $3.0 million.
FDIC insurance expense increased for the three and nine months ended September 30, 2024 compared to the same periods in 2023. On a year-to-date basis, the increase is primarily due to the Company’s recognition of approximately $5.2 million accrued in the first quarter of 2024 as a result of the FDIC special assessment on uninsured deposits in response to certain bank failures that occurred in 2023 as compared to the nine months ended September 30, 2023. For the three months ended September 30, 2024, the increased expense is primarily due to balance sheet growth as compared to the three months ended September 30, 2023.
Miscellaneous expense includes ATM expenses, correspondent bank charges, directors’ fees, telephone, postage, corporate insurance, dues and subscriptions, problem loan expenses and other miscellaneous operational losses and costs. During the three and nine months ended September 30, 2024, the company incurred $1.6 million and $2.5 million, respectively, in acquisition expenses related to the acquisition of Macatawa.

Income Taxes

The Company recorded income tax expense of $62.7 million in the third quarter of 2024 compared to $60.7 million in the third quarter of 2023. The effective tax rates were 26.95% in the third quarter of 2024 compared to 26.98% in the third quarter of 2023. During the first nine months of 2024, the Company recorded income tax expense of $184.3 million compared to $180.7 million for the first nine months of 2023. The effective tax rates were 26.56% for the first nine months of 2024 and 26.58% for the first nine months of 2023.

The effective tax rates were partially 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 shared-based awards. The Company recorded net excess tax benefits of $4.4 million in the first nine months of 2024, compared to net excess tax benefits of $2.9 million in the first nine months of 2023 related to share-based compensation, most of which was recorded in the first quarter for each year.

Operating Segment Results

The Company’s operations consist of three primary segments: community banking, specialty finance and wealth management. Refer to Note (13) “Segment Information” to the Consolidated Financial Statements in Item 1 of this report for further information on the Company’s primary segments. 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.

The community banking segment’s net interest income for the quarter ended September 30, 2024 totaled $396.9 million as compared to $360.6 million for the same period in 2023, an increase of $36.3 million, or 10%. On a year-to-date basis, net interest income for the nine months ended September 30, 2024 and September 30, 2023 was $1.1 billion. The increase in the third quarter of 2024, was primarily attributable to increased interest and fees on loans . The community banking segment’s non-interest income totaled $66.3 million in the third quarter of 2024, an decrease of $4.2 million , or 6% , when compared to the third quarter of 2023 total of $70.5 million . On a year-to-date basis, non-interest income totaled $212.6 million for the nine months ended September 30, 2024 , an increase of $5.2 million , or 2% , compared to $207.4 million for the nine months ended September 30, 2023. The increase in the nine month period was primarily the result of gains on investment securities and increased service charges on deposit accounts, partially offset by decreased mortgage banking revenue due to the decrease in the fair value of MSRs related to the changes in fair value model assumptions. The community banking segment recorded provision for credit losses of $20.5 million and $77.2 million, respectively, for the three and nine months ended September 30, 2024, compared to $16.7 million and $64.6 million, respectively, for the same periods in 2023. The increase in provision for credit losses for the three and nine month period was primarily the result of loan growth, including $15.5 million in Day 1 provision related to the acquisition of Macatawa, coupled with losses experienced in the Commercial and Commercial Real
61

Estate portfolios. The community banking segment’s net income for each of the quarters ended September 30, 2024 and September 30, 2023 totaled $115.2 million. On a year-to-date basis, the net income of the community banking segment for the nine months ended September 30, 2024 totaled $326.5 million as compared to $351.9 million for the nine months ended September 30, 2023.

The specialty finance segment’s net interest income totaled $88.4 million for the quarter ended September 30, 2024, compared to $85.4 million for the same period in 2023, an increase of $3.0 million, or 4%. On a year-to-date basis, net interest income for the segment increased $25.2 million, or 10%, compared to the same period in 2023. The increase for the three and nine month period was primarily due to loan growth and increased interest rates on the premium finance receivables portfolios. The specialty finance segment’s non-interest income increased to $29.6 million from $20.8 million for the three months ended September 30, 2024 and 2023, respectively, and stood at $89.2 million and $78.3 million for the nine months ended September 30, 2024 and 2023, respectively. Our property and casualty insurance premium finance operations, life insurance finance operations, lease financing operations and accounts receivable finance operations accounted for 51%, 29%, 18% and 2%, respectively, of the net revenues of our specialty finance business for the nine month period ended September 30, 2024. The net income of the specialty finance segment for the quarter ended September 30, 2024 totaled $46.8 million as compared to $40.5 million for the quarter ended September 30, 2023. On a year-to-date basis, the net income of the specialty finance segment for the nine months ended September 30, 2024 totaled $142.4 million as compared to $123.7 million for the nine months ended September 30, 2023.

The wealth management segment reported net interest income of $6.9 million for the third quarter of 2024 compared to $8.0 million in the same quarter of 2023, a decrease of $1.1 million, or 13%. On a year-to-date basis, net interest income totaled $22.6 million for the first nine months of 2024, as compared to $24.4 million for the first nine months of 2023. 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 $1.5 billion and $1.7 billion in the first nine months of 2024 and 2023, respectively. This segment recorded non-interest income of $37.4 million for the third quarter of 2024 compared to $37.3 million for the third quarter of 2023. On a year-to-date basis, this segment recorded non-interest income of $131.5 million for the first nine months of 2024 as compared to $101.0 million for the first nine months of 2023. The increase was primarily due to a $20.0 million gain recognized in the first quarter of 2024 related to the sale of the Company’s RBA division within the wealth management business. 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 $8.0 million for the third quarter of 2024 compared to $8.5 million for the third quarter of 2023. On a year-to-date basis, the wealth management segment’s net income totaled $40.8 million and $23.6 million for the nine month period ended September 30, 2024 and 2023, respectively.

Mortgage loans held-for-sale. Mortgage loans held-for-sale represents such 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 provide a source of non-interest revenue. The increase in average balance for the third quarter of 2024 as compared to the sequential and prior year periods is primarily due to higher mortgage origination production.

Loans, net of unearned income. Growth realized in the combined commercial and commercial real estate loan categories for the third quarter of 2024 as compared to the sequential and prior year periods is primarily attributable to increased business development efforts as well as loans acquired through the Macatawa acquisition. The aggregate balances of these loan categories comprised 59%, 58% and 57% of the average loan portfolio in the third quarter of 2024, second quarter of 2024 and third quarter of 2023, respectively.

Residential real estate loans averaged $3.2 billion in the third quarter of 2024, and increased $614.1 million, or 24%, from the average balance of $2.6 billion in the same period of 2023. Additionally, compared to the quarter ended June 30, 2024, the average balance increased $277.3 million, or 38% on an annualized basis. Growth is due to the Company continuing to allocate a portion of its mortgage production for investment instead of for subsequent sale into the secondary market.

The increase in the premium finance receivables during the third quarter of 2024 compared to the third quarter of 2023 was the result of continued originations within the portfolio due to hardening insurance market conditions driving a higher average size of new property and casualty insurance premium finance receivables as well as effective marketing and customer servicing. Approximately $4.8 billion of premium finance receivables were originated in the third quarter of 2024 compared to $4.6 billion during the same period of 2023. Premium finance receivables consist of a property and casualty portfolio and a life portfolio comprising approximately 47% and 53%, respectively, of the average total balance of premium finance receivables for the third quarter of 2024, and 46% and 54%, respectively, for the third quarter of 2023.

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.

63

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. 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.

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. Primarily as a result of growth in the Company’s commercial loan portfolio our allowance for credit losses in our commercial loan portfolio increased to $171.6 million as of September 30, 2024 compared to $151.5 million as of September 30, 2023.

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, southern Wisconsin and west Michigan, 69.4% of our commercial real estate loan portfolio is located in this region as of September 30, 2024. We have been able to effectively manage our total non-performing commercial real estate loans, aided by our credit management process. As of September 30, 2024, our allowance for credit losses related to this portfolio was $231.1 million compared to $215.7 million as of September 30, 2023 . The increase in the allowance for credit losses is primarily a result of growth in our commercial real estate portfolio. The table below sets forth the commercial real estate loans by property type and owner vs. non-owner occupied.

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.

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. Description of the Company’s credit risk rating structure used is included in Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations of the 2023 Form 10-K.

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.

Loan Portfolio Aging

As of September 30, 2024, excluding early buy-out loans guaranteed by U.S. government agencies, $83.1 million, or 0.2% of all loans, were 60 to 89 days (or two payments) past due and $204.0 million, or 0.4% of all loans, were 30 to 59 days (or one payment) past due. As of June 30, 2024, excluding early buy-out loans guaranteed by U.S. government agencies, $59.4 million, or 0.1% of all loans, were 60 to 89 days (or two payments) past due and $139.8 million, or 0.3% of all loans, were 30 to 59 days (or one payment) past due. Many of the commercial and commercial real estate loans shown as 60 to 89 days and 30 to 59 days past due are included on the Company’s internal problem loan reporting system. Loans on this system are closely monitored by management on a monthly basis. The Company's home equity and residential loan portfolios continue to exhibit low delinquency ratios. Home equity loans at September 30, 2024 that were current with regard to the contractual terms of the loan agreement represent 98.9% of the total home equity portfolio. Residential real estate loans, excluding early buy-out loans guaranteed by U.S. government agencies, at September 30, 2024 that were current with regards to the contractual terms of the loan agreements comprise 99.2% of total residential real estate loans outstanding. For more information regarding delinquent loans as of September 30, 2024, see Note (7) “Allowance for Credit Losses” in Item 1 of this report.

At this time, management believes reserves are appropriate to absorb losses that are expected upon the ultimate resolution of these credits. Significant increases may occur in subsequent periods due to ongoing macroeconomic uncertainty and related impacts on borrowers. Management will continue to actively review and monitor its loan portfolios, in an effort to identify problem credits in a timely manner.

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. A description of how the Company determines the allowance for credit losses is included in Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations of the 2023 Form 10-K.

Management determined that the allowance for credit losses was appropriate at September 30, 2024, 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.

Total average deposits $ 48,939,999 100 % $ 46,093,447 100 % $ 44,063,816 100 %

Total average deposits for the third quarter of 2024 were $48.9 billion, an increase of $4.9 billion, or 11%, from the third quarter of 2023. Total deposits increased in the third quarter primarily as a result of the Macatawa acquisition as well as the Company’s increased marketing efforts to retain and attract deposits to support continued loan growth. Additionally, the diversity of our deposit base showed its resilience in a volatile market. The Company has experienced a change in the mix of deposits as non-interest bearing deposits have migrated to interest-bearing products.

Wealth management deposits are funds from the brokerage customers of Wintrust Investments, CDEC and trust and asset management customers of the Company 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:
September 30, December 31,
(Dollars in thousands) 2024 2023 2023 2022 2021
Total deposits $ 51,404,966 $ 44,992,686 $ 45,397,170 $ 42,902,544 $ 42,095,585
Brokered deposits 4,080,401 3,693,997 4,216,718 3,174,093 1,591,083
Brokered deposits as a percentage of total deposits 7.9 % 8.2 % 9.3 % 7.4 % 3.8 %

Brokered deposits include certificates of deposit obtained through deposit brokers, deposits received through the Certificate of Deposit Account Registry Program, and certain 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 FHLB advances, notes payable, short-term borrowings, secured borrowings, subordinated debt 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.

(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 bank holding companies (“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 September 30, 2024 would exceed such revised well-capitalized standard.

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 (11) and (12) of the Consolidated Financial Statements in Item 1 for further information on these various funding sources. See Note (23) “Shareholders’ Equity” of the Consolidated Financial Statements presented under Item 7 of the 2023 Form 10-K for details on the Company’s issuance of Series D Preferred Stock in June 2015, Series E Preferred Stock and associated Depositary Shares in May 2020 and additional common stock offering in June 2022.

The 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, April and July of 2024, the Company declared a quarterly cash dividend of $0.45 per common share. In January, April, July and October of 2023, the Company declared a quarterly cash dividend of $0.40 per common share.

The Company continues to leverage its capital management framework to assess and monitor risk when making capital decisions. Management is committed to maintaining the Company’s capital levels above the “Well Capitalized” levels established by the FRB for bank holding companies.

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 addition to the liquidity management noted above, in the second quarter of 2024, the Company completed a loan sale transaction within our property and casualty insurance premium finance receivables portfolio which demonstrated that our premium finance portfolio is a strong source of additional liquidity if needed and demonstrated the flexibility to continue to manage our balance sheet effectively. Net proceeds to the Company totaled approximately $627.5 million and a gain on the sale was recorded for approximately $4.6 million. We maintain our liquid assets to ensure that we would have the balance sheet strength to serve our clients. As a result, the Company believes that it has sufficient funds and access to funds to effectively 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.

INFLATION

A banking organization’s assets and liabilities are primarily monetary. Changes in the rate of inflation typically 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 as material an impact on the Company’s business as entities operating in other industries. 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 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.

76

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 and decreases of 100 and 200 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 September 30, 2024, June 30, 2024 and September 30, 2023 is as follows:

September 30, 2023 1.7 1.2 (0.5) (2.4) %

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, 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) “Derivative Financial Instruments” of the Consolidated Financial Statements in Item 1 of this report for further information on the Company’s derivative financial instruments.

As shown above, the magnitude of potential changes in net interest income in various interest rate scenarios has continued to remain relatively neutral. Given the recent unprecedented rise in interest rates, the Company has made a conscious effort to reposition its exposure to changing interest rates given the uncertainty of the future interest rate environment. To this end, management has executed various derivative instruments including collars and receive fixed swaps to hedge variable rate loan exposures and originated a higher percentage of its loan originations in longer term fixed rate loans. The Company will continue to monitor current and projected interest rates and expects to execute additional derivatives to mitigate potential fluctuations in net interest margin in future periods.

Periodically, the Company enters into certain covered call option transactions related to certain securities held by the Company. 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 September 30, 2024 and September 30, 2023. See
77

Note (14) “Derivative Financial Instruments” of the Consolidated Financial Statements in Item 1 of this report for further information on the Company’s fees from covered call options for the nine months ended September 30, 2024 and September 30, 2023.

ITEM 4
CONTROLS AND PROCEDURES

As of the end of the period covered by this report, management of the Company, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as defined under Rules 13a-15(e) and 15d-15(e) of the Exchange Act. 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 were effective, in ensuring the information relating to the Company (and its consolidated subsidiaries) required to be disclosed by the Company in the reports it files or submits under the Exchange Act was recorded, processed, summarized and reported in a timely manner.

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.

Wintrust Mortgage California PAGA Matter

On May 24, 2022, a former Wintrust Mortgage employee filed a California Private Attorney General Act (“PAGA”) suit, not individually, but as representative of all Wintrust Mortgage’s California hourly employees, against Wintrust Mortgage in the Superior Court of San Diego County, California. Plaintiff alleges Wintrust Mortgage failed to provide: (i) accurate sick leave accrual and pay; (ii) overtime wages; (iii) accurately itemized wage statements; (iv) meal breaks and meal premiums; (v) timely payment of earned wages; (vi) payment of all earned wages; and (vii) payment of all vested vacation hours. Wintrust Mortgage disputes the validity of Plaintiff’s claims and believes, to the extent there were defects in complying with California law governing the payment of compensation to Plaintiff, such errors would have been de minimis. Plaintiff also has an arbitration agreement with a collective and class action waiver and on January 19, 2023, Wintrust Mortgage moved to compel arbitration. The court stayed litigation pending mediation, which was held on May 13, 2024. The parties agreed to settle the dispute for an immaterial amount. On October 16, 2024, the court entered an order approving the settlement.

Wintrust Mortgage Fair Lending Matter

On May 25, 2022, a Wintrust Mortgage customer filed a putative class action and asserted individual claims against Wintrust Mortgage and Wintrust Financial Corporation in the District Court for the Northern District of Illinois. Plaintiff alleges that Wintrust Mortgage discriminated against black/African American borrowers and brings class claims under the Equal Credit Opportunity Act, Sections 1981 and 1982 under Chapter 42 of the United States Code; and the Fair Housing Act of 1968. Plaintiff also asserts individual claims under theories of promissory estoppel, fraudulent inducement, and breach of contract. On September 23, 2022, Wintrust filed a motion to dismiss the entire suit and the court granted that motion to dismiss on September 27, 2023 and gave Plaintiff until October 20, 2023 to file an amended complaint. Plaintiff timely filed an amended complaint. Wintrust moved to dismiss the amended complaint on November 21, 2023. Wintrust vigorously disputes these allegations, believing them to be legally and factually meritless, and Wintrust otherwise lacks sufficient information to estimate the amount of any potential liability.
78

Wintrust Financial ERISA Matter

On July 29, 2022, a former Wintrust employee filed a class action in the District Court for the Northern District of Illinois asserting claims under the federal Employee Retirement Income Security Act (“ERISA”) against Wintrust Financial Corporation. Plaintiff alleges Wintrust breached its fiduciary duty in the selection of BlackRock Target Date funds for inclusion in its 401(k) plan, that Wintrust failed to monitor the performance of those funds, and in the alternative, Wintrust should be liable for breach of trust. Plaintiff’s sole basis for the allegations is that BlackRock Target Date funds allegedly performed more poorly than two comparable funds over a three-year period. Wintrust is one of several public companies that were sued on identical grounds within the same week by the same plaintiff’s law firm. On November 8, 2022, Wintrust filed a motion to dismiss the entire complaint. On July 14, 2023, the District Court granted Wintrust’s motion to dismiss and gave Plaintiff until August 2, 2023 to file an amended complaint. Plaintiff timely filed an amended complaint which Wintrust moved to dismiss on September 14, 2023. On August 14, 2024, the district court granted Wintrust’s motion with prejudice. On September 9, 2024, Plaintiff timely appealed to the Seventh Circuit. Plaintiff’s opening brief is due on December 18, 2024 and Wintrust’s response brief is due on January 31, 2025. We continue to believe that plaintiff’s allegations continue to be legally and factually meritless, that the district court correctly dismissed the amended complaint, and otherwise lack sufficient information to estimate the amount of any potential liability.

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.
