Wintrust Financial Corporation Reports Record Net Income

ROSEMONT, Ill., Jan. 20, 2026 (GLOBE NEWSWIRE) — Wintrust Financial Corporation (“Wintrust”, “the Company”, “we” or “our”) (Nasdaq: WTFC) announced record net income of $823.8 million, or $11.40 per diluted common share, for the year ended December 31, 2025 compared to net income of $695.0 million, or $10.31 per diluted common share for 2024. Pre-tax, pre-provision income (non-GAAP) for the year ended December 31, 2025 totaled a record $1.2 billion, compared to $1.0 billion for 2024.

The Company reported record quarterly net income of $223.0 million, or $3.15 per diluted common share, for the fourth quarter of 2025, compared to net income of $216.3 million, or $2.78 per diluted common share for the third quarter of 2025. Pre-tax, pre-provision income (non-GAAP) for the fourth quarter of 2025 totaled a record $329.8 million, as compared to $317.8 million for the third quarter of 2025.

Timothy S. Crane, President and Chief Executive Officer, commented, “We are pleased with our strong 2025 results, including the 19% improvement in net income. Throughout the year, we leveraged our unique position in the markets we serve to achieve robust growth in both loans and deposits. Wintrust ended the year with solid momentum evidenced by record net income, record net interest income, a stable net interest margin and strong balance sheet growth.”

Additionally, Mr. Crane noted, “Net interest margin in the fourth quarter remained within our expected range, improving by four basis points to 3.54%. The improvement in net interest margin, coupled with strong average earning asset growth, supported record net interest income in the fourth quarter of 2025. As we look ahead, we remain encouraged by the outlook and believe that a relatively stable net interest margin, combined with continued balance sheet growth, positions us well to deliver net interest income expansion in future quarters.”

Highlights of the fourth quarter of 2025:Comparative information to the third quarter of 2025, unless otherwise noted

Total loans increased by $1.0 billion, or 8% annualized.

Total deposits increased by $1.0 billion, or 7% annualized.

Total assets increased by $1.5 billion, or 9% annualized.

Net interest income increased to $583.9 million in the fourth quarter of 2025, up $16.9 million from $567.0 million in the third quarter of 2025, driven by improvement in net interest margin and strong average earning asset growth.

Net interest margin increased to 3.52% (3.54% on a fully taxable-equivalent basis, non-GAAP) during the fourth quarter of 2025.

Non-interest income was impacted by the following:

Net gains on investment securities totaled $1.5 million in the fourth quarter of 2025, compared to net gains of $3.0 million in the third quarter of 2025.

Provision for credit losses totaled $27.6 million in the fourth quarter of 2025, compared to a provision for credit losses of $21.8 million in the third quarter of 2025.

Net charge-offs totaled $21.8 million, or 17 basis points of average total loans on an annualized basis, in the fourth quarter of 2025 down from $24.6 million, or 19 basis points of average total loans on an annualized basis, in the third quarter of 2025.

Non-performing loans totaled $185.8 million and comprised 0.35% of total loans at December 31, 2025, as compared to $162.6 million and 0.31% of total loans at September 30, 2025.

Mr. Crane noted, “We continued our consistent, strong loan growth as loans increased $1.0 billion, or 8% on an annualized basis in the fourth quarter of 2025. Loan pipelines remain strong and we remain disciplined in our evaluation of credit opportunities, ensuring that loan growth aligns with our conservative credit standards. Strong deposit growth totaled $1.0 billion, or 7% on an annualized basis, in the fourth quarter of 2025. Our loan growth was funded by deposit growth in the fourth quarter of 2025 resulting in a stable loans-to-deposits ratio”

Commenting on credit quality, Mr. Crane stated, “Disciplined credit management, supported by persistent and thorough portfolio reviews, continues to drive positive outcomes through early identification and resolution of problem credits. We continue to be conservative and disciplined in our underwriting to maintain our strong credit standards. We believe the Company’s reserves are appropriate and we remain committed to sustaining high credit quality as evidenced by our low levels of net charge-offs and non-performing loans as well as our core loan allowance for credit losses of 1.32%.”

In summary, Mr. Crane concluded, “We believe our record fourth quarter and full year financial results highlight the strength of our differentiated business model that allows us to deliver sophisticated solutions with the personalized service, expertise and local decision making that our customers value. We remain focused on delivering disciplined and strategic organic growth that enhances our franchise in our core markets and specialty businesses while generating long-term value for our shareholders.”

Total assets increased $1.5 billion in the fourth quarter of 2025 compared to the third quarter of 2025. Total loans increased by $1.0 billion compared to the third quarter of 2025. The increase in loans was driven primarily by growth across most major loan categories.

Total liabilities increased by $1.3 billion in the fourth quarter of 2025 compared to the third quarter of 2025, driven by a $1.0 billion increase in total deposits. Strong organic deposit growth in the fourth quarter of 2025 was driven by our diverse deposit product offerings. Non-interest bearing deposit balances represented 20% of total deposits and have remained stable in recent quarters. The Company’s loans-to-deposits ratio ended the quarter at 92.0%.

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

For the fourth quarter of 2025, net interest income totaled $583.9 million, an increase of $16.9 million compared to the third quarter of 2025. The $16.9 million increase in net interest income in the fourth quarter of 2025 was driven by net interest margin improvement and average earning asset growth of $1.1 billion, or 7% annualized.

Net interest margin was 3.52% (3.54% on a fully taxable-equivalent basis, non-GAAP) during the fourth quarter of 2025, up four basis points compared to the third quarter of 2025. The yield on earning assets declined 14 basis points during the fourth quarter of 2025 primarily due to a 17 basis point decrease in loan yields. Funding cost on interest-bearing deposits decreased by 25 basis points compared to the third quarter of 2025, which more than offset the reduction in loan yields. The net free funds contribution in the fourth quarter of 2025 declined six basis points compared to the third quarter of 2025.

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

The allowance for credit losses totaled $460.5 million as of December 31, 2025, a slight increase from $454.6 million as of September 30, 2025. A provision for credit losses totaling $27.6 million was recorded for the fourth quarter of 2025 compared to $21.8 million recorded in the third quarter of 2025. The provision for credit losses recognized in the fourth quarter of 2025 reflects stable credit quality and a mostly stable macroeconomic forecast. However, given future economic performance remains uncertain, qualitative additions were made to the provision related to credit spreads and equity market valuations. For more information regarding the allowance for credit losses and provision for credit losses, see Table 11 in this report.

Management believes the allowance for credit losses is appropriate to account for expected credit losses. The Company is required to estimate expected credit losses over the life of the Company’s financial assets as of the reporting date. There can be no assurances, however, that future losses will not significantly exceed the amounts provided for, thereby affecting future results of operations. A summary of the allowance for credit losses calculated for the loan components in each portfolio as of December 31, 2025, September 30, 2025, and June 30, 2025 is shown on Table 12 of this report.

Net charge-offs totaled $21.8 million in the fourth quarter of 2025, a decrease of $2.8 million compared to $24.6 million of net charge-offs in the third quarter of 2025. Net charge-offs as a percentage of average total loans were 17 basis points in the fourth quarter of 2025 on an annualized basis compared to 19 basis points on an annualized basis in the third quarter of 2025. For more information regarding net charge-offs, see Table 10 in this report.

The Company’s loan portfolio delinquency rates remain low and manageable. For more information regarding past due loans, see Table 13 in this report.

Non-performing assets and non-performing loans increased slightly compared to prior quarter but stayed within the range experienced at the end of the prior three quarters of 2025. Non-performing assets totaled $206.6 million and comprised 0.29% of total assets as of December 31, 2025, as compared to $187.5 million, or 0.27% of total assets, as of September 30, 2025. Non-performing loans totaled $185.8 million and comprised 0.35% of total loans at December 31, 2025, as compared to $162.6 million and 0.31% of total loans at September 30, 2025. For more information regarding non-performing assets, see Table 14 in this report.

Non-interest income totaled $130.4 million in the fourth quarter of 2025, decreasing $0.4 million, compared to $130.8 million in the third quarter of 2025.

Wealth management revenue increased by approximately $2.2 million in the fourth quarter of 2025, compared to the third quarter of 2025. The increase in the fourth quarter of 2025 was primarily driven by an increase in asset valuations within the quarter, coupled with an increase in brokerage revenue related to higher transactional business. Wealth management revenue is comprised of the trust and asset management revenue of Wintrust Private Trust Company and Great Lakes Advisors, the brokerage commissions, managed money fees and insurance product commissions at Wintrust Investments and fees from tax-deferred like-kind exchange services provided by the Chicago Deferred Exchange Company.

Mortgage banking revenue totaled $22.6 million in the fourth quarter of 2025, compared to $24.5 million in the third quarter of 2025. The decrease in the fourth quarter of 2025 was primarily attributed to lower production revenue. For more information regarding mortgage banking revenue, see Table 16 in this report.

The Company recognized approximately $1.5 million in net gains on investment securities in the fourth quarter of 2025 compared to approximately $3.0 million in net gains in the third quarter of 2025. The net gains in the fourth quarter of 2025 were primarily the result of unrealized gains on the Company’s equity investment securities with a readily determinable fair value.

For more information regarding non-interest income, see Table 15 in this report.

Non-interest expense totaled $384.5 million in the fourth quarter of 2025, increasing $4.5 million, compared to $380.0 million in the third quarter of 2025. Non-interest expense, as a percent of average assets, decreased two basis points in the fourth quarter of 2025 to 2.19%.

Salaries and employee benefits expense increased by approximately $2.9 million in the fourth quarter of 2025, compared to the third quarter of 2025. This was primarily driven by an increased level of health insurance claims in the fourth quarter of 2025.

The Company recorded net OREO expense of $2.2 million in the fourth quarter of 2025, compared to net OREO expense of $262,000 in the third quarter of 2025. The primary diver of the increase in the fourth quarter can be attributed to valuation adjustments. Net OREO expenses include all costs associated with obtaining, maintaining and selling other real estate owned properties as well as valuation adjustments.

Advertising and marketing expenses in the fourth quarter of 2025 totaled $13.8 million, which was a $5.2 million decrease as compared to the third quarter of 2025. The decrease in the current quarter relates primarily to lower sports sponsorships. Marketing costs are incurred to promote the Company’s brand, commercial banking capabilities and the Company’s various products, to attract loans and deposits and to announce new branch openings as well as the expansion of the Company’s non-bank businesses. The level of marketing expenditures depends on the timing of sponsorship programs utilized which are determined based on the market area, targeted audience, competition and various other factors. Generally, these expenses are elevated in the second and third quarters of each year.

Travel and entertainment expense increased approximately $1.9 million in the fourth quarter of 2025, compared to the third quarter of 2025. The increase is primarily attributed to seasonal corporate events that occur in the fourth quarter.

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

The Company recorded income tax expense of $79.2 million in the fourth quarter of 2025 compared to $79.8 million in the third quarter of 2025. The effective tax rates were 26.2% in the fourth quarter of 2025 compared to 27.0% in the third quarter of 2025. The effective tax rates were impacted by an overall lower level of provision for state income tax expense in the comparable periods.

Through community banking, the Company provides banking and financial services primarily to individuals, small to mid-sized businesses, local governmental units and institutional clients residing primarily in the local areas the Company services. In the fourth quarter of 2025, community banking increased its commercial, commercial real estate and residential real estate loan portfolios.

Mortgage banking revenue was $22.6 million for the fourth quarter of 2025, a decrease of $1.8 million compared to the third quarter of 2025. See Table 16 for more detail. Service charges on deposit accounts totaled $20.4 million in the fourth quarter of 2025 as compared to $19.8 million in the third quarter of 2025. The Company’s gross commercial and commercial real estate loan pipelines remained solid as of December 31, 2025 indicating momentum for expected continued loan growth in the first quarter of 2026.

Through specialty finance, the Company offers financing of insurance premiums for businesses and individuals, equipment financing through structured loans and lease products to customers in a variety of industries, accounts receivable financing and value-added, out-sourced administrative services and other services. Originations within the insurance premium financing receivables portfolios were $5.4 billion during the fourth quarter of 2025. Average balances decreased by $61.2 million, as compared to the third quarter of 2025. The Company’s leasing divisions’ portfolio balances increased in the fourth quarter of 2025, with capital leases, loans, and equipment on operating leases of $2.9 billion, $1.2 billion, and $360.6 million as of December 31, 2025, respectively, compared to $2.8 billion, $1.2 billion, and $301.0 million as of September 30, 2025, respectively. Revenues from the Company’s out-sourced administrative services business were $1.4 million in the fourth quarter of 2025, which was relatively stable compared to the third quarter of 2025.

Through wealth management, the Company offers a full range of wealth management services, including trust and investment services, tax-deferred like-kind exchange services, asset management, and securities brokerage services. Wealth management revenue totaled $39.4 million in the fourth quarter of 2025, an increase as compared to the third quarter of 2025. At December 31, 2025, the Company’s wealth management subsidiaries had approximately $56.1 billion of assets under administration, which included $9.6 billion of assets owned by the Company and its subsidiary banks.

TABLE 8: INTEREST RATE SENSITIVITY

As an ongoing part of its financial strategy, the Company attempts to manage the impact of fluctuations in market interest rates on net interest income. Management measures its exposure to changes in interest rates by modeling many different interest rate scenarios.

The following interest rate scenarios display the percentage change in net interest income over a one-year time horizon assuming increases and decreases of 100 and 200 basis points as compared to projected net interest income in a scenario with no assumed rate changes. The Static Shock Scenario results incorporate actual cash flows and repricing characteristics for balance sheet instruments following an instantaneous, parallel change in market rates based upon a static (i.e. no growth or constant) balance sheet. Conversely, the Ramp Scenario results incorporate management’s projections of future volume and pricing of each of the product lines following a gradual, parallel change in market rates over twelve months. Actual results may differ from these simulated results due to timing, magnitude, and frequency of interest rate changes as well as changes in market conditions and management strategies. The interest rate sensitivity for both the Static Shock and Ramp Scenario is as follows:

As shown above, the magnitude of potential changes in net interest income in various interest rate scenarios has continued to remain relatively neutral. As the current interest rate cycle progressed, management took action to reposition its sensitivity to interest rates. To this end, management has executed various derivative instruments including collars, floors 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 may execute additional derivatives to mitigate potential fluctuations in the net interest margin in future periods.

As noted in the table on the previous page, the majority of the Company’s portfolio is tied to SOFR and CMT indices which, as shown in the table above, do not mirror the same changes as the Prime rate, which has historically moved when the Federal Reserve raises or lowers interest rates. Specifically, the Company has variable rate loans of $18.5 billion tied to one-month SOFR and $7.7 billion tied to twelve-month CMT.

TABLE 18: SUPPLEMENTAL NON-GAAP FINANCIAL MEASURES/RATIOS

The accounting and reporting policies of Wintrust conform to generally accepted accounting principles (“GAAP”) in the United States and prevailing practices in the banking industry. However, certain non-GAAP performance measures and ratios are used by management to evaluate and measure the Company’s performance. These include taxable-equivalent net interest income (including its individual components), taxable-equivalent net interest margin (including its individual components), the taxable-equivalent efficiency ratio, tangible common equity ratio, tangible book value per common share, return on average tangible common equity, and pre-tax income, excluding provision for credit losses. Management believes that these measures and ratios provide users of the Company’s financial information a more meaningful view of the performance of the Company’s interest-earning assets and interest-bearing liabilities and of the Company’s operating efficiency. Other financial holding companies may define or calculate these measures and ratios differently.

Management reviews yields on certain asset categories and the net interest margin of the Company and its banking subsidiaries on a fully taxable-equivalent basis (“FTE”). 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 an FTE basis is also used in the calculation of the Company’s efficiency ratio. The efficiency ratio, which is calculated by dividing non-interest expense by total taxable-equivalent net revenue (less securities gains or losses), measures how much it costs to produce one dollar of revenue. Securities gains or losses are excluded from this calculation to better match revenue from daily operations to operational expenses. Management considers the tangible common equity ratio and tangible book value per common share as useful measurements of the Company’s equity. The Company references the return on average tangible common equity as a measurement of profitability. Management considers pre-tax income, excluding provision for credit losses, as a useful measurement of the Company’s core net income.
