Wintrust Financial Corporation Reports Record First Quarter 2024 Net Income

ROSEMONT, ILLINOIS – Wintrust Financial Corporation (“Wintrust”, “the Company”, “we” or “our”) (Nasdaq: WTFC) announced record quarterly net income of $187.3 million or $2.89 per diluted common share for the first quarter of 2024, an increase in diluted earnings per common share of 55% compared to the fourth quarter of 2023. Pre-tax, pre-provision income (non-GAAP) totaled a record $271.6 million, up 30% as compared to $208.2 million in the fourth quarter of 2023.

Timothy S. Crane, President and Chief Executive Officer, commented, “Following record net income in 2023, we continued our momentum with strong results to start 2024. We leveraged our balanced, multi-faceted business model and position as Chicago’s and Wisconsin’s bank to grow deposits and loans while maintaining our consistent credit standards coupled with expense management.”

Additionally, Mr. Crane noted, “The first quarter exhibited funding strong loan growth with competitively-priced deposits in accordance with the increased loan demand. Increasing our long-term franchise value and net interest income remains our focus as we consider opportunities in the markets we serve.”

Highlights of the first quarter of 2024:

Comparative information to the fourth quarter of 2023, unless otherwise noted

•Total loans increased by approximately $1.1 billion, or 10% annualized.

•Total deposits increased by approximately $1.1 billion, or 9% annualized.

•Total assets increased by $1.3 billion, or 9% annualized.

•Net interest margin decreased by five basis points to 3.57% (3.59% on a fully taxable-equivalent basis, non-GAAP) during the first quarter of 2024.

◦Net interest income decreased to $464.2 million in the first quarter of 2024 compared to $470.0 million in the fourth quarter of 2023, primarily due to one less day in the first quarter of 2024.

•Non-interest income was impacted by the following:

◦Gains of approximately $20.0 million from the sale of the Company’s Retirement Benefits Advisors (“RBA”) division. This gain was partially offset by additional commissions and incentive compensation totaling $701,000 related to the sale transaction.

◦Favorable net valuation adjustments related to certain mortgage assets totaled $2.3 million in the first quarter of 2024 compared to unfavorable net valuation adjustments of $9.7 million in the fourth quarter of 2023.

•Non-interest expense was negatively impacted by an accrual of $5.2 million for estimated amounts owed as a result of the FDIC special assessment on uninsured deposits in response to certain bank failures occurring in 2023. This is in addition to the related $34.4 million accrued in the fourth quarter of 2023 for the estimate of such FDIC special assessments.

•Provision for credit losses totaled $21.7 million in the first quarter of 2024 as compared to a provision for credit losses of $42.9 million in the fourth quarter of 2023.

•Net charge-offs totaled $21.8 million, or 21 basis points of average total loans on an annualized basis, in the first quarter of 2024 as compared to $14.9 million, or 14 basis points of average total loans on an annualized basis in the fourth quarter of 2023.

Mr. Crane noted, “Our net interest margin for the first quarter stayed within our expected range, decreasing by five basis points compared to the fourth quarter of 2023. The decrease in net interest margin was due primarily to certain seasonal declines in non-interest bearing deposit balances, deposit migration to interest-bearing products and competitive deposit pricing to fund quality loan growth. Loan growth during the first quarter totaled $1.1 billion, or 10% on an annualized basis. We are pleased with our diversified loan growth in the first quarter with strong loan origination activity in commercial and residential real estate portfolios, as well as growth in commercial real estate driven primarily by draws on existing loan facilities. Deposit growth in the first quarter of 2024 was utilized to fund our robust loan growth as deposits increased by approximately $1.1 billion, or 9% on an annualized basis. We continue to leverage our customer relationships and market positioning to generate deposits and build long term franchise value. Non-interest bearing deposits decreased due to seasonality during the first quarter while also experiencing some migration to interest-bearing products. Despite the slightly lower net interest income during the current period, we generated record quarterly net revenue through our diversified sources of revenue, including our mortgage banking and wealth management businesses.”

Commenting on credit quality, Mr. Crane stated, “Credit metrics have remained steady, aligning with historical averages. Net charge-offs totaled $21.8 million, or 21 basis points of average total loans on an annualized basis, in the first quarter of 2024 as compared to $14.9 million, or 14 basis points of average total loans on an annualized basis, in the fourth quarter of 2023. Approximately $11.9 million of charge-offs in the current quarter were previously reserved for in the fourth quarter of 2023 Non-performing loans totaled $148.4 million, or 0.34% of total loans, at the end of the first quarter of 2024 compared to $139.0 million, or 0.33% of total loans, at the end of the fourth quarter of 2023. We continue to conservatively and proactively review credit and maintain our consistently strong credit standards. The allowance for credit losses on our core loan portfolio as of March 31, 2024 was approximately 1.51% of the outstanding balance (see Table 11 for additional information). We believe that the Company’s reserves remain appropriate and we remain diligent in our review of credit.”

Mr. Crane added, “Late loan growth in the first quarter creates positive revenue momentum moving forward as period-end loan balances exceeded averages. We continue to see good opportunities in the markets we serve and feel well positioned to grow deposit and loan relationships in future quarters. Our focus remains on winning business and maximizing long term franchise value.”

In summary, Mr. Crane noted, “The quarter was strong, momentum remains good and we are excited about the agreement reached to acquire Macatawa Bank Corporation in Michigan (announced April 15, 2024). The ability to expand with a high quality bank with a strong low-cost core deposit base, excess liquidity, exceptional asset quality and a committed management team is a terrific fit for Wintrust.”

SUMMARY OF RESULTS:

BALANCE SHEET

Total assets increased $1.3 billion in the first quarter of 2024 as compared to the fourth quarter of 2023. Total loans increased by $1.1 billion as compared to the fourth quarter of 2023. The increase in loans was the result of diversified loan growth primarily across the commercial and residential real estate portfolios coupled with draws on existing commercial real-estate loan facilities.

Total liabilities increased by $1.3 billion in the first quarter of 2024 as compared to the fourth quarter of 2023 primarily due to a $1.1 billion increase in total deposits. Non-interest bearing deposits as a percentage of total deposits was 21% at March 31, 2024 compared to 23% at December 31, 2023. The Company's loans to deposits ratio ended the quarter at 93.1%.

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 first quarter of 2024, net interest income totaled $464.2 million, a decrease of $5.8 million as compared to the fourth quarter of 2023. The $5.8 million decrease in net interest income in the first quarter of 2024 compared to the fourth quarter of 2023 was primarily due to one less day during the period as well as a five basis point decrease in the net interest margin, partially offset by a $755.8 million increase in average earning assets.

Net interest margin was 3.57% (3.59% on a fully taxable-equivalent basis, non-GAAP) during the first quarter of 2024 compared to 3.62% (3.64% on a fully taxable-equivalent basis, non-GAAP) during the fourth quarter of 2023. The net interest margin decrease as compared to the fourth quarter of 2023 was primarily due to a 15 basis point increase in the rate paid on interest-bearing liabilities. This decrease was partially offset by a nine basis point increase in yield on earning assets and a one basis point increase in the net free funds contribution. The 15 basis point increase on the rate paid on interest-bearing liabilities in the first quarter of 2024 as compared to the fourth quarter of 2023 was primarily due to a 16 basis point increase in the rate paid on interest-bearing deposits. The nine basis point increase in the yield on earning assets in the first quarter of 2024 as compared to the fourth quarter of 2023 was primarily due to an 11 basis point expansion on loan yields.

For more information regarding net interest income, see Table 4 through Table 7 in this report.

ASSET QUALITY

The allowance for credit losses totaled $427.5 million as of March 31, 2024, relatively unchanged compared to $427.6 million as of December 31, 2023. A provision for credit losses totaling $21.7 million was recorded for the first quarter of 2024 as compared to $42.9 million recorded in the fourth quarter of 2023. For more information regarding the allowance for credit losses and provision for credit losses, see Table 10 in this report.

Management believes the allowance for credit losses is appropriate to account for expected credit losses. The Current Expected Credit Losses accounting standard requires the Company 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 March 31, 2024, December 31, 2023, and September 30, 2023 is shown on Table 11 of this report.

Net charge-offs totaled $21.8 million in the first quarter of 2024, as compared to $14.9 million of net charge-offs in the fourth quarter of 2023. The increase in net charge-offs during the first quarter of 2024 was primarily the result of increased net charge-offs within the commercial portfolio. Net charge-offs as a percentage of average total loans were 21 basis points in the first quarter of 2024 on an annualized basis compared to 14 basis points on an annualized basis in the fourth quarter of 2023. For more information regarding net charge-offs, see Table 9 in this report.

The Company’s delinquency rates remain low and manageable. For more information regarding past due loans, see Table 12 in this report.

Non-performing assets totaled $162.9 million and comprised 0.28% of total assets as of March 31, 2024, as compared to $152.3 million as of December 31, 2023. Non-performing loans totaled $148.4 million, or 0.34% of total loans, at March 31, 2024. The

8

increase in the first quarter of 2024 was primarily due to an increase in certain credits within the commercial real estate portfolio becoming nonaccrual as well as increases within the property and casualty insurance premium finance receivables portfolio, partially offset by a decrease within the commercial portfolio. For more information regarding non-performing assets, see Table 13 in this report.

Though these credit metrics increased during the period, net charge-offs as a percentage of average total loans and non-performing loans as a percentage of total loans remained at historically low levels in the first quarter of 2024.

NON-INTEREST INCOME

Wealth management revenue increased by $1.5 million in the first quarter of 2024 as compared to the fourth quarter of 2023 primarily due to increased asset management fees from higher assets under management during the period. Wealth management revenue is comprised of the trust and asset management revenue of The Chicago Trust Company and Great Lakes Advisors, the brokerage commissions, managed money fees and insurance product commissions at Wintrust Investments and fees from tax-deferred like-kind exchange services provided by the Chicago Deferred Exchange Company.

Mortgage banking revenue increased by $20.2 million in the first quarter of 2024 as compared to the fourth quarter of 2023 primarily due to a $5.0 million favorable valuation adjustment to the fair value of mortgage servicing rights, net of servicing hedge, in the first quarter of 2024 compared to a $16.1 million unfavorable adjustment in the fourth quarter of 2023, as well as $6.6 million higher in production revenue. This was partially offset by an unfavorable adjustment to the Company’s held-for-sale portfolio of early buy-out exercised loans guaranteed by U.S. government agencies, which are held at fair value, of $2.2 million in the first quarter of 2024 compared to a $4.9 million favorable adjustment in the fourth quarter of 2023. The Company monitors the relationship of these assets and seeks to minimize the earnings impact of fair value changes.

The Company recognized $1.3 million in net gains on investment securities in the first quarter of 2024 as compared to $2.5 million in net gains in the fourth quarter of 2023. The change from period to period was primarily the result of lower unrealized gains on the Company’s equity investment securities with a readily determinable fair value, partially offset by higher realized gains from the liquidation of an equity investment security without a readily determinable fair value in the first quarter of 2024.

Fluctuations in trading gains and losses in the first quarter of 2024 compared to the fourth quarter of 2023 were primarily the result of fair value adjustments related to interest rate derivatives not designated as hedges.

Other income increased by $17.6 million in the first quarter of 2024 compared to the fourth quarter of 2023 primarily due to a $20.0 million gain recognized related to the sale of the Company’s RBA division within its wealth management business. This was partially offset by an unfavorable adjustment to the Company’s held-for-investment portfolio of early buy-out exercised loans guaranteed by U.S. government agencies, which are held at fair value, of $2.1 million when compared to the fourth quarter of 2023, as well as lower interest rate swap fees and unfavorable foreign currency remeasurement adjustments.

For more information regarding non-interest income, see Table 14 in this report.

NON-INTEREST EXPENSE

Salaries and employee benefits expense increased by $1.2 million in the first quarter of 2024 as compared to the fourth quarter of 2023. The $1.2 million increase is primarily related to higher commissions from increased mortgage production as well as commissions related to the sale of the Company’s RBA division within its wealth management business in the first quarter of 2024. This was partially offset by lower employee benefits as employee insurance decreased in the first quarter of 2024.

Advertising and marketing expenses in the first quarter of 2024 totaled $13.0 million, which is a $4.1 million decrease as compared to the fourth quarter of 2023 primarily due to a decrease in digital advertising and sponsorships.

FDIC insurance, including amounts accrued for estimated special assessments, decreased $29.1 million in the first quarter of 2024 as compared to the fourth quarter of 2023. This was primarily the result of a lower accrual recognized in the first quarter of 2024 for estimated amounts owed as a result of the FDIC special assessment on uninsured deposits in response to certain bank failures occurring in 2023. The Company recognized $5.2 million in the first quarter of 2024 for such special assessment compared to $34.4 million in the fourth quarter of 2023.

The Company recorded OREO expense of $392,000 in the first quarter of 2024, compared to net OREO income of $1.6 million in the fourth quarter of 2023 related to realized gains on sales of OREO.

INCOME TAXES

The Company recorded income tax expense of $62.7 million in the first quarter of 2024 compared to $41.8 million in the fourth quarter of 2023. The effective tax rates were 25.07% in the first quarter of 2024 compared to 25.27% in the fourth quarter of 2023. The effective tax rates were partially impacted by the tax effects related to share-based compensation which fluctuate based on the Company’s stock price and timing of employee stock option exercises and vesting of other share-based awards. The Company recorded net excess tax benefits of $4.4 million in the first quarter of 2024, compared to net excess tax benefits of $53,000 in the fourth quarter of 2023 related to share-based compensation. The effective tax rates were also partially impacted due to an overall lower level of pre-tax net income in the comparable periods, primarily due to the accrual for the estimated amount owed as a result of the FDIC special assessment on uninsured deposits. The Company recorded an estimated FDIC special assessment accrual of $5.2 million in the first quarter of 2024, compared to a $34.4 million accrual in the fourth quarter of 2023.

BUSINESS UNIT SUMMARY

Community Banking

Through its community banking unit, 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 first quarter of 2024, the community banking unit expanded its commercial, commercial real estate and residential real estate loan portfolios.

Mortgage banking revenue was $27.7 million for the first quarter of 2024, an increase of $20.2 million as compared to the fourth quarter of 2023, primarily due to a $5.0 million favorable valuation adjustment to the fair value of mortgage servicing rights, net of servicing hedge, in the first quarter of 2024 compared to a $16.1 million unfavorable adjustment in the fourth quarter of 2023, as well as $6.6 million higher in production revenue. This was partially offset by an unfavorable adjustment to the Company’s held-for-sale portfolio of early buy-out exercised loans guaranteed by U.S. government agencies, which are held at fair value, of $2.2 million in the first quarter of 2024 compared to a $4.9 million favorable adjustment in the fourth quarter of 2023. Service charges on deposit accounts totaled $14.8 million in the first quarter of 2024, which was relatively stable compared to the fourth quarter of 2023. The Company’s gross commercial and commercial real estate loan pipelines remained solid as of March 31, 2024 indicating momentum for expected continued loan growth in the second quarter of 2024.

Specialty Finance

Through its specialty finance unit, 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 $4.6 billion during the first quarter of 2024 and average balances increased by $12.5 million as compared to the fourth quarter of 2023. The Company’s leasing portfolio balance increased in the first quarter of 2024, with its portfolio of assets, including capital leases, loans and equipment on operating leases, totaling $3.6 billion as of March 31, 2024 as compared to $3.4 billion as of December 31, 2023. Revenues from the Company’s out-sourced administrative services business were $1.2 million in the first quarter of 2024, which was relatively stable compared to the fourth quarter of 2023.

Wealth Management

Through four separate subsidiaries within its wealth management unit, 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. See “Items Impacting Comparative Results,” regarding the sale of the RBA division during the first quarter of 2024. Wealth management revenue totaled $34.8 million in the first quarter of 2024, increasing $1.5 million in the first quarter of 2024 as compared to the fourth quarter of 2023 primarily due to increased asset management fees from higher assets under management during the period. At March 31, 2024, the Company’s wealth management subsidiaries had approximately $48.7 billion of assets under administration, which included $8.8 billion of assets owned by the Company and its subsidiary banks, representing an increase from the $47.1 billion of assets under administration at December 31, 2023.

Certain returns, yields, performance ratios, or quarterly growth rates are “annualized” in this presentation to represent an annual time period. This is done for analytical purposes to better discern, for decision-making purposes, underlying performance trends when compared to full-year or year-over-year amounts. For example, a 5% growth rate for a quarter would represent an annualized 20% growth rate.

TABLE 7: 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. 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
Mar 31, 2024	1.9	%	1.4	%	1.5	%	1.6	%
Dec 31, 2023	2.6		1.8		0.4		(0.7)
Sep 30, 2023	3.3		1.9		(2.0)		(5.2)
Jun 30, 2023	5.7		2.9		(2.9)		(7.9)
Mar 31, 2023	4.2		2.4		(2.4)		(7.3)

Ramp Scenario	+200 Basis Points		+100 Basis Points		-100 Basis Points		-200 Basis Points
Mar 31, 2024	0.8	%	0.6	%	1.3	%	2.0	%
Dec 31, 2023	1.6		1.2		(0.3)		(1.5)
Sep 30, 2023	1.7		1.2		(0.5)		(2.4)
Jun 30, 2023	2.9		1.8		(0.9)		(3.4)
Mar 31, 2023	3.0		1.7		(1.3)		(3.4)

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

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 $11.6 billion tied to one-month SOFR and $6.1 billion tied to one-year CMT. The above chart shows:

TABLE 16: 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. In this non-GAAP presentation, net interest income is adjusted to reflect tax-exempt interest income on an equivalent before-tax basis using tax rates effective as of the end of the period. This measure ensures comparability of net interest income arising from both taxable and tax-exempt sources. Net interest income on a fully taxable-equivalent basis is also used in the calculation of the Company’s efficiency ratio. The efficiency ratio, which is calculated by dividing non-interest expense by total taxable-equivalent net revenue (less securities gains or losses), measures how much it costs to produce one dollar of revenue. Securities gains or losses are excluded from this calculation to better match revenue from daily operations to operational expenses. Management considers the tangible common equity ratio and tangible book value per common share as useful measurements of the Company’s equity. The Company references the return on average tangible common equity as a measurement of profitability. Management considers pre-tax income, excluding provision for credit losses, as a useful measurement of the Company’s core net income.
