Wintrust Financial Corporation Reports Record Net Income

ROSEMONT, ILLINOIS – Wintrust Financial Corporation (“Wintrust”, “the Company”, “we” or “our”) (Nasdaq: WTFC) announced record net income of $461.1 million, or $6.52 per diluted common share, for the first six months of 2026 compared to net income of $384.6 million, or $5.47 per diluted common share, for the same period of 2025. This represents a year-to-date net income increase of 20% compared to the same period of 2025. Pre-tax, pre-provision income (non-GAAP) for the first six months of the year totaled a record $671.6 million, compared to $566.3 million for the first six months of 2025.

The Company reported record quarterly net income of $233.7 million, or $3.30 per diluted common share, for the second quarter of 2026, compared to net income of $227.4 million, or $3.22 per diluted common share, for the first quarter of 2026. Pre-tax, pre-provision income (non-GAAP) for the second quarter of 2026 totaled a record $341.1 million, as compared to $330.5 million for the first quarter of 2026.

Timothy S. Crane, President and Chief Executive Officer, commented, “We are pleased to deliver record results for the first six months of the year. Second quarter 2026 represents the sixth consecutive quarter of record net income for the Company. Strong diversified loan growth funded by robust organic deposit growth highlights the underlying strength of our business model. We continue to leverage our customer relationships and unique market positioning to grow the balance sheet and create long term franchise value.”

Additionally, Mr. Crane noted, “Net interest margin in the second quarter remained within our expected range at 3.52% and we generated record net interest income attributable to strong average earning asset growth. Building on our momentum, we believe consistent balance sheet growth, coupled with a stable net interest margin, should result in net interest income expansion in future quarters.”

Highlights of the second quarter of 2026:
Comparative information to the first quarter of 2026, unless otherwise noted

•Total loans increased by $1.6 billion, or 12% annualized.
•Total deposits increased by $2.2 billion, or 15% annualized.

◦Net interest margin decreased to 3.50% (3.52% on a fully taxable-equivalent basis, non-GAAP) during the second quarter of 2026 primarily due to lower loan yields.
•Non-interest expense was impacted by the following:
◦A $5.2 million reversal of an FDIC special assessment accrued in the first quarter of 2024. The special assessments were in response to certain bank failures in 2023 and the reversal is based on the FDIC's final determination of losses to its Deposit Insurance Fund.    


•Provision for credit losses totaled $23.1 million in the second quarter of 2026, compared to a provision for credit losses of $29.6 million in the first quarter of 2026.

“Looking ahead, our pipelines remain strong and we believe we are well-positioned to generate consistent balance sheet growth while maintaining our disciplined underwriting standards. We remain committed to growing net interest income and exercising prudent expense management, which position us to deliver positive operating leverage for 2026”, Mr. Crane said.

SUMMARY OF RESULTS:

BALANCE SHEET

Total assets increased $2.5 billion in the second quarter of 2026 compared to the first quarter of 2026, driven by a $1.6 billion increase in total loans. The strong loan growth was diversified across all major loan categories, including seasonally higher growth in our Premium Finance Receivables - Property and Casualty portfolio.

Total liabilities increased by $2.4 billion in the second quarter of 2026 compared to the first quarter of 2026, driven by a $2.2 billion increase in total deposits. Robust organic deposit growth in the second quarter of 2026 was driven by our diverse customer base and product offerings. Non-interest bearing deposit balances represented 19% of total deposits and average non-interest bearing deposit balances have remained stable in recent quarters. The Company's loans-to-deposits ratio ended the quarter at 91.0%.

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.

NET INTEREST INCOME

For the second quarter of 2026, net interest income totaled $597.4 million, compared to $579.0 million in the first quarter of 2026. The increase in net interest income in the second quarter of 2026 was driven by robust average earning asset growth of $2.1 billion.

Net interest margin was 3.50% (3.52% on a fully taxable-equivalent basis, non-GAAP) during the second quarter of 2026, down four basis points compared to the first quarter of 2026. The yield on earning assets declined four basis points during the second quarter of 2026 primarily due to a seven basis point decrease in loan yields. Funding cost on interest-bearing deposits remained unchanged compared to the first quarter of 2026. The net free funds contribution in the second quarter of 2026 was flat compared to the first quarter of 2026.

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

ASSET QUALITY

The allowance for credit losses totaled $481.2 million as of June 30, 2026, an increase from $471.6 million as of March 31, 2026. A provision for credit losses totaling $23.1 million was recorded for the second quarter of 2026 compared to $29.6 million recorded in the first quarter of 2026. The provision for credit losses recognized in the second quarter of 2026 reflects stable credit quality and a mostly stable macroeconomic forecast. However, given future economic performance remains uncertain, allowance results capture uncertainty related to credit spreads, equity market valuations, consumer & business sentiment, and the job market. 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 June 30, 2026, March 31, 2026, and December 31, 2025 is shown on Table 12 of this report.

Net charge-offs totaled $13.4 million in the second quarter of 2026, a decrease of $5.0 million compared to $18.4 million of net charge-offs in the first quarter of 2026. Net charge-offs as a percentage of average total loans were 10 basis points in the second quarter of 2026 on an annualized basis compared to 14 basis points on an annualized basis in the first quarter of 2026. For more information regarding net charge-offs, see Table 10 in this report.

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

Non-performing assets and non-performing loans were stable compared to prior quarter. Non-performing assets totaled $195.2 million and comprised 0.26% of total assets as of June 30, 2026, as compared to $200.2 million, or 0.28% of total assets, as of March 31, 2026. Non-performing loans totaled $179.3 million and comprised 0.32% of total loans at June 30, 2026, as
8

compared to $182.7 million and 0.34% of total loans at March 31, 2026. For more information regarding non-performing assets, see Table 14 in this report.

NON-INTEREST INCOME

Non-interest income totaled $141.3 million in the second quarter of 2026, compared to $134.1 million in the first quarter of 2026.

Wealth management revenue decreased by approximately $2.2 million in the second quarter of 2026, compared to the first quarter of 2026. The decrease in the second quarter of 2026 was primarily driven by performance based revenues on certain customer relationships which positively impacted results in the first quarter of 2026. 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 $27.4 million in the second quarter of 2026, compared to $23.4 million in the first quarter of 2026. The increase in the second quarter of 2026 was primarily attributed to higher operational revenue. For more information regarding mortgage banking revenue, see Table 16 in this report.

The Company recognized approximately $1.8 million in net gains on investment securities in the second quarter of 2026 compared to approximately $31,000 in net losses in the first quarter of 2026. The net gains in the second quarter of 2026 were primarily the result of fair value adjustments 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

Non-interest expense totaled $397.5 million in the second quarter of 2026, increasing $14.9 million, compared to $382.6 million in the first quarter of 2026. Non-interest expense, as a percent of average assets, remained stable at 2.21% in the second quarter of 2026.

Salaries and employee benefits expense increased by approximately $5.6 million in the second quarter of 2026, compared to the first quarter of 2026. This was primarily driven by higher commissions and incentives expense attributable to an increase in mortgage originations and a full quarter impact of the annual merit increases reflected in base salaries.

Advertising and marketing expense in the second quarter of 2026 totaled $20.4 million, which was a $7.2 million increase as compared to the first quarter of 2026. The increase in the second quarter was primarily driven by summer sports sponsorships and other community sponsorship events. 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.

FDIC insurance totaled $6.6 million in the second quarter of 2026, a $4.4 million decrease from the first quarter of 2026. This was primarily the result of a reversal of the $5.2 million FDIC special assessment recorded in the first quarter of 2024. The special assessments were in response to certain bank failures in 2023 and the reversal is based on the FDIC's final determination of losses to its Deposit Insurance Fund.

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

INCOME TAXES

The Company recorded income tax expense of $84.3 million in the second quarter of 2026 compared to $73.6 million in the first quarter of 2026. The effective tax rates were 26.5% in the second quarter of 2026 compared to 24.4% in the first quarter of 2026. The effective tax rates were impacted by the tax effects related to share-based compensation which fluctuate based on the Company’s stock price and timing of employee stock option exercises and vesting of other share-based awards. The Company recorded net excess tax benefits of $140,000 in the second quarter of 2026, compared to net excess tax benefits of $6.6 million in the first quarter of 2026 related to share-based compensation.

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:

Static Shock Scenario +200 Basis Points +100 Basis Points -100 Basis Points -200 Basis Points
Jun 30, 2026 (2.4) % (1.1) % (0.1) % (0.1) %
Mar 31, 2026 (0.8) (0.1) (1.0) (1.9)
Dec 31, 2025 (1.6) (0.5) (0.5) (0.8)
Sep 30, 2025 (2.3) (0.8) 0.0  (0.4)
Jun 30, 2025 (1.5) (0.4) (0.2) (1.2)

Ramp Scenario +200 Basis Points +100 Basis Points -100 Basis Points -200 Basis Points
Jun 30, 2026 (0.2) % (0.1) % (0.2) % (0.4) %
Mar 31, 2026 (0.1) 0.0  (0.1) (0.3)
Dec 31, 2025 (0.0) 0.1  (0.1) (0.2)
Sep 30, 2025 (0.2) (0.1) 0.1  (0.1)
Jun 30, 2025 0.0  0.0  (0.1) (0.4)

As shown above, the magnitude of potential changes in net interest income in various interest rate scenarios has continued to remain relatively neutral. Management has taken action to reposition its sensitivity to interest rates to stabilize net interest margin following the rise in short term interest rates in 2022 and 2023. To this end, management has executed various derivative instruments including collars, floors and receive-fixed swaps to hedge variable-rate loan exposures. 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 $20.0 billion tied to one-month SOFR and $8.2 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 a 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.
