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 and on December 31, 2024, the funds were disbursed to the settlement administrator. The settlement administrator disbursed the settlement funds during the first quarter of 2025, bringing this matter to conclusion. 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 and on February 5, 2026, the court granted Wintrust’s motion with prejudice. 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 146 resolution of these matters, if unfavorable, may be material to the results of operations or financial condition for a particular period. (21) 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, collars and floors 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 potential 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. 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. 147 The table below presents the fair value of the Company’s derivative financial instruments as of December 31, 2025 and December 31, 2024: Derivative Assets Derivative Liabilities (In thousands) December 31, 2025 December 31, 2024 December 31, 2025 December 31, 2024 Derivatives designated as hedging instruments under ASC 815: Interest rate derivatives designated as Cash Flow Hedges $ 53,622 $ 7,329 $ 3,363 $ 56,084 Interest rate derivatives designated as Fair Value Hedges 5,350 10,001 496 87 Total derivatives designated as hedging instruments under ASC 815 $ 58,972 $ 17,330 $ 3,859 $ 56,171 Derivatives not designated as hedging instruments under ASC 815: Interest rate derivatives $ 116,562 $ 177,553 $ 116,745 $ 183,799 Interest rate lock commitments 3,416 1,950 — 18 Forward commitments to sell mortgage loans 104 1,297 2,729 88 Commodity forward contracts 448 766 288 583 Foreign exchange contracts 165 1,131 153 1,091 Total derivatives not designated as hedging instruments under ASC 815 $ 120,695 $ 182,697 $ 119,915 $ 185,579 Total Derivatives $ 179,667 $ 200,027 $ 123,774 $ 241,750 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, collars and floors 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 specified in the contract exceeds the agreed upon cap strike rate or in which the interest rate specified in the contract is below the agreed upon floor strike rate at the end of each period. Interest rate floors designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates fall below the strike rate on the contract in exchange for an upfront premium. As of December 31, 2025, the Company had various interest rate collar, swap and floor 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 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 December 31, 2025: December 31, 2025 (In thousands) Range of Maturities Notional Amount Fair Value Asset (Liability) Floor at 1-month CME Term SOFR September 2028 - December 2029 $ 450,000 $ 2,095 Interest rate collars at 1-month CME term SOFR October 2026 - September 2027 1,750,000 ( 2,208 ) Interest rate swaps at 1-month CME term SOFR (1) February 2026 - October 2031 4,650,000 50,372 Total Cash Flow Hedges $ 6,850,000 $ 50,259 (1) The notional amount includes forward-starting swaps that are not yet effective. 148 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 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 the Term 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 the Term 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. A rollforward of the amounts in accumulated other comprehensive income or loss related to interest rate derivatives designated as cash flow hedges, including such derivative contracts terminated during the period, follows: Years Ended December 31, (In thousands) 2025 2024 Unrealized (loss) gain at beginning of period $ ( 15,508 ) $ 43,538 Amount reclassified from accumulated other comprehensive income or loss to interest income or expense on deposits, loans and other borrowings 16,311 72,674 Amount of gain (loss) recognized in other comprehensive income or loss 66,309 ( 131,720 ) Unrealized gain (loss) at end of period $ 67,112 $ ( 15,508 ) As of December 31, 2025, the Company estimated that during the next 12 months, $ 16.9 million will be reclassified from accumulated other comprehensive income or loss as an increase 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 $ 3.6 million reclassified as an increase to interest income related to the interest rate collars floors 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 December 31, 2025, the Company had 13 interest rate swaps with an aggregate notional amount of $ 118.4 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. 149 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 December 31, 2025: December 31, 2025 (In thousands) Derivatives in Fair Value Hedging Relationships Location in the Statement of Condition Carrying Amount of the Hedged Assets/(Liabilities) Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets/(Liabilities) Cumulative Amount of Fair Value Hedging Adjustment Remaining for any Hedged Assets/(Liabilities) for which Hedge Accounting has been Discontinued Interest rate swaps Loans, net of unearned income $ 113,117 $ ( 4,810 ) $ ( 31 ) Available-for-sale debt securities 456 ( 2 ) — The following table presents the gain or loss recognized related to derivative instruments that are designated as fair value hedges for the respective period: (In thousands) Location of Gain or (Loss) Recognized in Income on Derivative Year Ended December 31, Derivatives in Fair Value Hedging Relationships 2025 Interest rate swaps Interest and fees on loans $ ( 7 ) Non-Designated Hedges The Company does not use derivatives for speculative purposes. Derivatives not designated as accounting hedges are used to manage the Company’s economic exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements of ASC 815. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. 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 December 31, 2025 and 2024, the Company had interest rate derivative transactions with an aggregate notional amount of approximately $ 15.2 billion and $ 13.3 billion, respectively, (all interest rate swaps and caps with customers and third parties) related to this program. At December 31, 2025, these interest rate derivatives had maturity dates ranging from January 2026 to August 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 our residential mortgage loan production when interest rate lock commitments are entered into in order to economically hedge the effect of future changes in interest rates on its commitments to fund the loans as well as on its portfolio of mortgage loans held-for-sale. The Company’s mortgage banking derivatives have not been designated as being in hedge relationships. At December 31, 2025 and 2024, the Company had interest rate lock commitments with an aggregate notional amount of approximately $ 161.9 million and $ 120.7 million and forward commitments to sell mortgage loans with an aggregate notional amount of approximately $ 413.2 million and $ 377.5 million. 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 150 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 December 31, 2025 and 2024, the Company had commodity derivative transactions with an aggregate notional amount of approximately $ 4.1 million and $ 5.2 million, respectively, (all forward contracts with customers and third parties) related to this program. At December 31, 2025, these commodity derivatives had maturity dates ranging from January 2026 to October 2027. 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 December 31, 2025 and 2024, the Company held foreign currency derivatives with an aggregate notional amount of approximately $ 84.0 million and $ 97.1 million, respectively. 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 December 31, 2025 or December 31, 2024. 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. At December 31, 2025 the Company held ten interest rate derivatives with an aggregate notional value of $ 362.0 million and ten interest rate derivatives with an aggregate notional value of $ 295.0 million at December 31, 2024 for such purpose of economically hedging a portion of the fair value adjustment related to its mortgage servicing rights portfolio. Amounts included in the Consolidated Statements of Income related to derivative instruments not designated in hedge relationships were as follows: (In thousands) Years Ended December 31, Derivative Location in income statement 2025 2024 Interest rate swaps and caps Trading gains, net $ ( 250 ) $ 59 Mortgage banking derivatives Mortgage banking ( 2,004 ) 952 Commodity contracts Trading gains, net ( 24 ) 184 Foreign exchange contracts Trading gains, net 204 ( 84 ) Covered call options Fees from covered call options 20,681 10,196 Derivative contract held as economic hedge on MSRs Mortgage banking 5,272 ( 7,909 ) 151 Credit Risk Derivative instruments have inherent risks, primarily market risk and credit risk. Market risk is associated with changes in the value of an underlying asset. Credit risk relates to the risk that the counterparty will fail to perform according to the terms of the agreement. The Company is exposed to the credit risk of its commercial borrowers and third party financial institutions who are counterparties to interest rate derivatives with the Company. The counterparty credit risk associated with the mirror-image swaps executed with third party financial institutions, is monitored and managed as part of the Company’s overall asset-liability management process, except that the counterparty credit risk related to derivatives entered into with certain qualified borrowers is managed through the Company’s standard loan underwriting process for commercial borrowers since these derivatives typically share in the collateral provided by the loan agreements. When deemed necessary, appropriate types and amounts of collateral are obtained to minimize credit exposure. The Company hedges the market risk of derivatives transactions with commercial borrowers by entering into offsetting transactions with large, highly rated financial institutions. These exposures are generally secured by cash under bilateral Credit Support Annexes (“CSAs”), which are a component of the International Swaps and Derivatives Association (“ISDA”) Master Agreements executed with counterparties. Aggregate counterparty exposures are monitored against various types of credit limits established to contain risk within parameters. Counterparty credit risk is managed by the Counterparty Credit Risk Management team in accordance with SR 11-10, Interagency Counterparty Credit Risk Guidance , which was issued in 2011 in response to the financial crisis of 2008. The guidance addresses counterparty credit risk governance, measurement, management, and systems. Specifically, counterparty risk is managed through the establishment and regular review of exposure limits, formalization of limits in policy and procedure, ongoing review of models, and having a single platform to allow for the timely aggregation of exposures. The Counterparty Credit Risk Management team uses a variety of approaches to monitor counterparty financial performance, including monitoring of credit exposure versus limits, use of early warning reports, and daily and intraday monitoring of financial developments. 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. If the Company were to breach any of these provisions, at a time when the derivatives subject to such agreements are in a liability position, and the derivatives were to be terminated as a result, the Company would be required to settle its obligations under the agreements at the termination value and would be required to pay any additional amounts due in excess of amounts previously posted as collateral with the respective counterparty. As of December 31, 2025, there were $ 2.0 million derivatives that were subject to such agreements in a net liability position. The Company records interest rate derivatives subject to master netting agreements at their gross value and does not offset derivative assets and liabilities on the Consolidated Statements of Condition. The table below summarizes the Company’s interest rate derivatives and offsetting positions as of the dates shown. Derivative Assets Derivative Liabilities Fair Value Fair Value (In thousands) December 31, 2025 December 31, 2024 December 31, 2025 December 31, 2024 Gross Amounts Recognized $ 175,534 $ 194,883 $ 120,604 $ 239,970 Less: Amounts offset in the Statements of Condition — — — — Net amount presented in the Statements of Condition $ 175,534 $ 194,883 $ 120,604 $ 239,970 Gross amounts not offset in the Statements of Condition Offsetting Derivative Positions $ ( 60,108 ) $ ( 74,656 ) $ ( 60,108 ) $ ( 74,656 ) Collateral Posted ( 46,894 ) ( 78,550 ) ( 1,963 ) — Net Credit Exposure $ 68,532 $ 41,677 $ 58,533 $ 165,314 152 (22) Fair Value 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 December 31, 2025, the Company classified $ 99.6 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, southern Wisconsin and west Michigan 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. For the year ended December 31, 2025, 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 December 31, 2025 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 December 31, 2025, the Company classified $ 53.8 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 December 31, 2025 was 5.02 %. 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 0.92 % with a credit loss discount ranging from 0 % to 35 % at December 31, 2025. Loans held-for-investment — The fair value of loans held-for-investment 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. 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 December 31, 2025, the Company classified $ 56.2 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 December 31, 2025 was 5.12 %. 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 9.92 % at December 31, 2025. 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 1.51 % with credit loss discounts ranging from 0 % to 22 % at December 31, 2025. 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 December 31, 2025, the Company classified $ 195.0 million of MSRs as Level 3. The weighted average discount rate used as an input to value the pool of MSRs at December 31, 2025 was 9.83 % with discount rates applied ranging from 9 % to 15 %. 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 % to 86 % or a weighted average prepayment speed of 9.92 %. Further, for current and delinquent loans, the Company assumed a weighted average cost of servicing of $ 76 and $ 382 , 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 (6) “Mortgage Servicing Rights (“MSRs”)” for further discussion of MSRs. Derivative instruments — The Company’s derivative instruments include swaps, collars and purchased options such as caps and floors, 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 December 31, 2025, the Company classified $ 3.4 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 154 fund. The weighted-average pull-through rate at December 31, 2025 was 83.02 % with pull-through rates applied ranging from 10 % 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.

At December 31, 2025, approximately $ 700,000 of mortgage loans held-for-sale were classified as nonaccrual compared to $ 4.0 million as of December 31, 2024. Additionally, there were $ 53.1 million of loans past due greater than 90 days and still accruing interest within the mortgage loans held-for-sale portfolio as of December 31, 2025 compared to $ 59.3 million as of December 31, 2024. All of the nonaccrual loans and loans past due greater than 90 days and still accruing within the mortgage 155 loans held-for-sale portfolio as of December 31, 2025 and December 31, 2024 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 December 31, 2025 and 2024 for loans held-for-investment measured at fair value under ASC 825 was $ 148.1 million and $ 157.8 million, respectively, while the aggregate fair value of loans held-for-investment was $ 151.6 million and $ 158.8 million, respectively, as shown in the above tables. The changes in Level 3 assets measured at fair value on a recurring basis during the years ended December 31, 2025 and 2024 are summarized as follows: (In thousands) Municipal Mortgage loans held-for-sale Loans held-for-investment MSRs Derivative assets Balance at January 1, 2025 $ 121,607 $ 60,399 $ 34,896 $ 203,788 $ 1,950 Total net gains (losses) included in: Net income (1) — 1,829 555 ( 8,765 ) 1,466 Other comprehensive income or loss ( 12,178 ) — — — — Purchases 42,387 — — — — Settlements ( 52,213 ) ( 105,867 ) ( 35,591 ) — — Net transfers into Level 3 — 97,453 56,340 — — Balance at December 31, 2025 $ 99,603 $ 53,814 $ 56,200 $ 195,023 $ 3,416 (In thousands) Municipal Mortgage loans held-for-sale Loans held-for-investment MSRs Derivative assets Balance at January 1, 2024 $ 86,237 $ 26,835 $ 60,670 $ 192,456 $ 4,510 Total net gains (losses) included in: Net income (1) — 370 ( 43 ) 11,332 ( 2,560 ) Other comprehensive income or loss ( 11,212 ) — — — — Purchases 84,839 — — — — Settlements ( 38,257 ) ( 48,555 ) ( 43,525 ) — — Net transfers into Level 3 — 81,749 17,794 — — Balance at December 31, 2024 $ 121,607 $ 60,399 $ 34,896 $ 203,788 $ 1,950 (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 December 31, 2025. December 31, 2025 Year Ended December 31, 2025 Fair Value Losses Recognized, net (In thousands) Total Level 1 Level 2 Level 3 Individually assessed loans - foreclosure probable and collateral-dependent $ 137,209 $ — $ — $ 137,209 $ 61,222 Other real estate owned (1) 20,839 — — 20,839 2,668 Total $ 158,048 $ — $ — $ 158,048 $ 63,890 (1) Net fair value losses recognized on other real estate owned include valuation adjustments and charge-offs during the respective period. 156 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 (5) “Allowance for Credit Losses”. At December 31, 2025, the Company had $ 137.2 million of individually assessed loans classified as Level 3. All of the $ 137.2 million of individually assessed loans were measured at fair value based on the underlying collateral of the loan as shown in the table above. None were valued based on discounted cash flows in accordance with ASC 310,”Receivables.” 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 December 31, 2025, the Company had $ 20.8 million of other real estate owned classified as Level 3. The unobservable input applied to other real estate owned relates to the 10 % reduction to the appraisal value representing the estimated cost of sale of the foreclosed property. A higher discount for the estimated cost of sale results in a decreased carrying value. 157 The valuation techniques and significant unobservable inputs used to measure both recurring and non-recurring Level 3 fair value measurements at December 31, 2025 were as follows: (Dollars in thousands) Fair Value Valuation Methodology Significant Unobservable Input Input / Range of Inputs Weighted Average of Inputs Impact to valuation from an increased or higher input value Measured at fair value on a recurring basis: Municipal securities $ 99,603 Bond pricing Equivalent rating BBB-AA+ N/A Increase Mortgage loans held-for-sale 53,814 Discounted cash flows Discount rate 5.02 % 5.02 % Decrease Credit discount 0 % - 35 % 0.92 % Decrease Loans held-for-investment 56,200 Discounted cash flows Discount rate 5.02 % - 6.00 % 5.12 % Decrease Credit discount 0 % - 22 % 1.51 % Decrease Constant prepayment rate (CPR) - current loans 9.92 % 9.92 % Decrease Average life - delinquent loans (in years) 1.4 years - 12.0 years 5.9 years Decrease MSRs 195,023 Discounted cash flows Discount rate 9 % - 15 % 9.83 % Decrease Constant prepayment rate (CPR) 6 % - 86 % 9.92 % Decrease Cost of servicing $ 70 - $ 200 $ 76 Decrease Cost of servicing - delinquent $ 200 - $ 1,000 $ 382 Decrease Derivatives 3,416 Discounted cash flows Pull-through rate 10 % - 100 % 83.02 % Increase Measured at fair value on a non-recurring basis: Individually assessed loans - foreclosure probable and collateral-dependent 137,209 Appraisal value Appraisal adjustment - cost of sale 10 % 10.00 % Decrease Other real estate owned 20,839 Appraisal value Appraisal adjustment - cost of sale 10 % 10.00 % Decrease 158 The Company is required under applicable accounting guidance to report the fair value of all financial instruments on the Consolidated Statements of Condition, including those financial instruments carried at cost.

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, southern Wisconsin, and west Michigan 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 (commercial, residential real estate, etc.) and category within each type (construction, non-construction, franchise lending etc.). Each category is further segmented by interest rate type (fixed and variable). The fair value of both fixed and variable rate loans is estimated by discounting scheduled cash flows through the 159 estimated maturity using estimated market discount rates that reflect credit and interest rate risks inherent in the loan. In accordance with ASC 820, the Company has categorized loans as a Level 3 fair value measurement. Deposits with stated maturities — The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently in effect for deposits of similar remaining maturities. In accordance with ASC 820, the Company has categorized deposits with stated maturities as a Level 3 fair value measurement. FHLB advances — The fair value of FHLB advances is calculated using 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.

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” 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 tables 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”. Our Chief Executive Officer is our chief operating decision maker (“CODM”). The CODM uses income before taxes to review segment performance and allocate resources for each reportable segment. Financial information regarding each significant segment expense outlined below is regularly provided (at least monthly) to the CODM. For community banking and specialty finance segments, ‘Interest expense’ is a significant segment expense. Additionally, for each of the three reportable segments, ‘Salaries’, ‘Commissions and incentive compensation’ and ‘Benefits’ are significant segment expenses. 162 The following is a summary of certain operating information for reportable segments: (In thousands) Community Banking Specialty Finance Wealth Management Total Operating Segments Intersegment Eliminations Consolidated 2025 Interest income $ 3,223,220 $ 420,528 $ 38,147 $ 3,681,895 $ 46,138 $ 3,728,033 Interest expense 1,462,186 41,131 664 1,503,981 — 1,503,981 Net interest income 1,761,034 379,397 37,483 2,177,914 46,138 2,224,052 Provision for credit losses 89,050 6,503 — 95,553 — 95,553 Non-interest income 310,981 129,713 154,387 595,081 ( 93,141 ) 501,940 Non-interest expense: Salaries 390,817 64,829 38,966 494,612 1,958 496,570 Commissions and incentive compensation 133,733 38,911 49,124 221,768 — 221,768 Benefits 122,421 22,167 10,366 154,954 — 154,954 Other segment expenses (1) 553,208 96,812 37,681 687,701 ( 48,961 ) 638,740 Total non-interest expense 1,200,179 222,719 136,137 1,559,035 ( 47,003 ) 1,512,032 Income before taxes 782,786 279,888 55,733 1,118,407 — 1,118,407 Income tax expense 206,119 74,589 13,855 294,563 — 294,563 Net income $ 576,667 $ 205,299 $ 41,878 $ 823,844 $ — $ 823,844 Total assets at end of year $ 57,333,741 $ 12,502,367 $ 1,305,938 $ 71,142,046 $ — $ 71,142,046 2024 Interest income $ 3,001,500 $ 405,317 $ 30,765 $ 3,437,582 $ 40,015 $ 3,477,597 Interest expense 1,465,237 49,030 795 1,515,062 — 1,515,062 Net interest income 1,536,263 356,287 29,970 1,922,520 40,015 1,962,535 Provision for credit losses 88,345 12,702 — 101,047 — 101,047 Non-interest income 279,845 119,339 168,134 567,318 ( 78,993 ) 488,325 Non-interest expense: Salaries 364,144 61,070 38,989 464,203 1,769 465,972 Commissions and incentive compensation 130,516 36,130 48,873 215,519 — 215,519 Benefits 106,994 18,686 9,937 135,617 — 135,617 Other segment expenses (1) 500,327 91,479 34,557 626,363 ( 40,747 ) 585,616 Total non-interest expense 1,101,981 207,365 132,356 1,441,702 ( 38,978 ) 1,402,724 Income before taxes 625,782 255,559 65,748 947,089 — 947,089 Income tax expense 167,072 69,214 15,758 252,044 — 252,044 Net income $ 458,710 $ 186,345 $ 49,990 $ 695,045 $ — $ 695,045 Total assets at end of year $ 52,500,643 $ 11,234,012 $ 1,145,013 $ 64,879,668 $ — $ 64,879,668 2023 Interest income $ 2,462,103 $ 362,035 $ 33,867 $ 2,858,005 $ 35,109 $ 2,893,114 Interest expense 1,021,128 32,991 1,131 1,055,250 — 1,055,250 Net interest income 1,440,975 329,044 32,736 1,802,755 35,109 1,837,864 Provision for credit losses 104,895 9,495 — 114,390 — 114,390 Non-interest income 263,023 105,992 136,561 505,576 ( 71,470 ) 434,106 Non-interest expense: Salaries 340,993 57,024 39,129 437,146 1,666 438,812 Commissions and incentive compensation 110,986 30,395 40,720 182,101 — 182,101 Benefits 100,190 17,070 9,840 127,100 — 127,100 Other segment expenses (1) 484,263 82,024 36,226 602,513 ( 38,027 ) 564,486 Total non-interest expense 1,036,432 186,513 125,915 1,348,860 ( 36,361 ) 1,312,499 Income before taxes 562,671 239,028 43,382 845,081 — 845,081 Income tax expense 148,612 63,484 10,359 222,455 — 222,455 Net income $ 414,059 $ 175,544 $ 33,023 $ 622,626 $ — $ 622,626 Total assets at end of year $ 44,355,786 $ 10,664,887 $ 1,239,261 $ 56,259,934 $ — $ 56,259,934 (1) Other segment items include non-interest expense categories such as ‘Software & Equipment’, ‘Data processing’, ‘Advertising and Marketing’, ‘FDIC Insurance’, and ‘Occupancy’.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE The Company made no changes in and had no disagreements with its independent accountants during the two most recent fiscal years or any subsequent interim period. ITEM 9A. CONTROLS AND PROCEDURES Disclosure Controls and Procedures As of the end of the period covered by this Annual Report on Form 10-K, 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. Changes in Internal Control Over Financial Reporting There were no changes in the Company’s internal control over financial reporting that occurred during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. 166 Report on Management’s Assessment of Internal Control Over Financial Reporting Wintrust Financial Corporation is responsible for the preparation, integrity, and fair presentation of the consolidated financial statements included in this Annual Report on Form 10-K. The consolidated financial statements and notes included in this Annual Report on Form 10-K have been prepared in conformity with generally accepted accounting principles in the United States and necessarily include some amounts that are based on management’s best estimates and judgments. We, as management of Wintrust Financial Corporation, are responsible for establishing and maintaining adequate internal control over financial reporting that is designed to produce reliable financial statements in conformity with generally accepted accounting principles in the United States. The system of internal control over financial reporting as it relates to the financial statements is evaluated for effectiveness by management and tested for reliability through a program of internal audits. Actions are taken to correct potential deficiencies as they are identified. Any system of internal control, no matter how well designed, has inherent limitations, including the possibility that a control can be circumvented or overridden and misstatements due to error or fraud may occur and not be detected. Also, because of changes in conditions, internal control effectiveness may vary over time. Accordingly, even an effective system of internal control will provide only reasonable assurance with respect to financial statement preparation. Management assessed the Company’s system of internal control over financial reporting as of December 31, 2025, in relation to criteria for the effective internal control over financial reporting as described in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO Criteria). Based on this assessment, management concluded that, as of December 31, 2025, the Company's system of internal control over financial reporting is effective and meets the criteria of the COSO Criteria. Ernst & Young LLP (PCAOB ID 42 ), the independent registered public accounting firm that audited the Company's financial statements included in this Annual Report on Form 10-K, has issued an attestation report on management’s assessment of the Corporation’s internal control over financial reporting. Their report expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025. /s/ Timothy S. Crane /s/ David L. Stoehr Timothy S. Crane David L. Stoehr President and Executive Vice President & Chief Executive Officer Chief Financial Officer Rosemont, Illinois February 26, 2026 167 Report of Independent Registered Public Accounting Firm To the Shareholders and the Board of Directors of Wintrust Financial Corporation Opinion on Internal Control Over Financial Reporting We have audited Wintrust Financial Corporation and subsidiaries’ internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Wintrust Financial Corporation and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of condition of the Company as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and our report dated February 26, 2026 expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Report on Management’s Assessment of Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP Chicago, Illinois February 26, 2026 168 ITEM 9B.
