Wintrust Financial Corporation Reports Record Year-to-Date Net Income

ROSEMONT, ILLINOIS – Wintrust Financial Corporation (“Wintrust”, “the Company”, “we” or “our”) (Nasdaq: WTFC) announced record net income of $499.1 million or $7.71 per diluted common share for the first nine months of 2023 compared to net income of $364.9 million or $5.78 per diluted common share for the same period of 2022, an increase in diluted earnings per common share of 33%. Pre-tax, pre-provision income (non-GAAP) for the first nine months of 2023 totaled $751.3 million as compared to $536.3 million in the first nine months of 2022, an increase in pre-tax, pre-provision income of 40%.

The Company recorded quarterly net income of $164.2 million or $2.53 per diluted common share for the third quarter of 2023, an increase in diluted earnings per common share of 6% compared to the second quarter of 2023 and 14% compared to the third quarter of 2022. Pre-tax, pre-provision income (non-GAAP) totaled $244.8 million as compared to $239.9 million for the second quarter of 2023 and $206.5 million for the third quarter of 2022.

Timothy S. Crane, President and Chief Executive Officer, commented, “As demonstrated by our strong results, we followed our record first half of 2023 with continued momentum in the third quarter of 2023. We leveraged our position in the markets we serve to sustain growth in loans and deposits during the quarter.”

Additionally, Mr. Crane noted, “Our net interest margin for the quarter was within our expected range, down slightly due primarily to the impact of hedging activities. In the current interest rate environment, we expect to maintain our net interest margin within a narrow range around current levels for the remainder of 2023 and continuing into the beginning of 2024. We believe this growth and stability in net interest margin will drive strong financial performance in future quarters.”

Highlights of the third quarter of 2023:

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

•Total deposits grew by approximately $1 billion, or 9% annualized.

•Total loans increased by approximately $423 million, or 4% annualized. Adjusting for the impact of a loan sale transaction within our property and casualty insurance premium finance receivables portfolio during the third quarter of 2023, total loans would have increased $767 million, or 7% annualized.

•Record quarterly net interest income of $462.4 million, increasing approximately $14.8 million primarily due to strong growth in earning assets.

◦Net interest margin decreased four basis points to 3.60% (3.62% on a fully taxable-equivalent basis, non-GAAP) during the third quarter of 2023 primarily due to the negative impact of hedging activities.

•Non-interest expense was negatively impacted by:

◦Occupancy costs of approximately $2.9 million from the impairment of two Company-owned buildings that are no longer being used.

◦Data processing costs of approximately $1.5 million from the termination of a duplicate service contract related to the acquisition of a wealth management business in 2023.

◦Other salary costs of approximately $1.6 million related to acquisition-related severance charges and other contractually due compensation costs.

•Provision for credit losses totaled $19.9 million in the third quarter of 2023 as compared to a provision for credit losses of $28.5 million in the second quarter of 2023.

•Net charge-offs totaled $8.1 million or eight basis points of average total loans on an annualized basis in the third quarter of 2023 as compared to $17.0 million or 17 basis points of average total loans on an annualized basis in the second quarter of 2023.

Mr. Crane commented, “By leveraging our customer relationships, market positioning, diversified products and competitive rates, we continued to generate significant deposit growth, increasing deposits approximately $1 billion, or 9% on an annualized basis, in the third quarter of 2023. Growth in retail deposits helped reduce our level of brokered deposits by approximately $392 million during the third quarter of 2023. In addition, deposit growth helped fund approximately $423 million of loan growth during the quarter. This strong loan growth was achieved despite the impact of a loan sale transaction within our property and casualty insurance premium finance receivables portfolio that reduced period-end balances at the end of the third quarter by approximately $344 million. Loan growth came primarily from draws on existing commercial real estate loan facilities as well as growth in our commercial portfolio. Additionally, despite the loan sale transaction noted above, our property and casualty insurance premium finance receivables portfolio ended the quarter relatively unchanged. We remain prudent in our review of credit prospects ensuring our loan growth stays within our conservative credit standards.”

Mr. Crane noted, “We grew our net interest income during the third quarter of 2023 by approximately $14.8 million primarily due to an increase in average earning assets of approximately $1.6 billion. Our net interest margin decreased four basis points during the third quarter, however, three basis points of the decline was due to the impact of our interest rate hedging strategies, which are designed to protect our net interest income if interest rates decline. Deposit pricing pressures moderated in the third quarter of 2023 and we expect that to continue into the fourth quarter. Assuming a similar interest rate environment, we believe our net interest margin will be relatively stable for the remainder of 2023 and entering 2024. The combination of balance sheet growth and a stable net interest margin is expected to continue to grow our net interest income.”

Commenting on credit quality, Mr. Crane stated, “Credit metrics remained strong and at historically low levels. Net charge-offs totaled $8.1 million or eight basis points of average total loans on an annualized basis in the third quarter of 2023 as compared to $17.0 million or 17 basis points of average total loans on an annualized basis in the second quarter of 2023. Non-performing loans totaled $133.1 million, or 0.32% of total loans, at the end of the third quarter of 2023 compared to $108.7 million, or 0.26% of total loans, at the end of the second quarter of 2023. Of the $24.4 million increase in non-performing loans in the third quarter of 2023, $19.6 million is related to the premium finance receivables portfolios in which we ultimately expect minimal losses. The allowance for credit losses on our core loan portfolio as of September 30, 2023 was approximately 1.51% of the outstanding balance (see Table 12 for additional information). We believe that the Company’s reserves remain appropriate and we remain diligent in our review of credit.”

Mr. Crane concluded, “I am very pleased with our results for the third quarter of 2023. Net income for the quarter was the second highest in our history, behind only the net income reported in the first quarter of 2023. Total loans as of September 30, 2023 were $739 million higher than average total loans in the third quarter of 2023, which is expected to help continue our momentum into the fourth quarter. We continue to win business and expand our franchise, keeping us well-positioned in the markets we serve. This will help grow our deposit and loan relationships, which should generate higher net revenues and earnings in the coming quarters. As a result, our capital ratios will benefit from the increased earnings.”

The graphs below illustrate certain financial highlights of the third quarter of 2023 as well as historical financial performance. See “Supplemental Non-GAAP Financial Measures/Ratios” at Table 17 for additional information with respect to non-GAAP financial measures/ratios, including the reconciliations to the corresponding GAAP financial measures/ratios.

SUMMARY OF RESULTS:

BALANCE SHEET

Total assets increased $1.3 billion in the third quarter of 2023 as compared to the second quarter of 2023. Total loans increased by $422.6 million as compared to the second quarter of 2023. The increase in loans was primarily the result of draws on existing commercial real estate loan facilities as well as growth in the commercial portfolio. Additionally, despite a loan sale transaction that reduced outstanding balances at the end of the third quarter of 2023 by $344 million, the property and casualty insurance premium finance receivables portfolio ended the quarter relatively unchanged. In the third quarter of 2023, the Company purchased securities, resulting in a $480.7 million increase in investment securities.

Total liabilities increased by $1.3 billion in the third quarter of 2023 as compared to the second quarter of 2023 primarily due to a $1.0 billion increase in total deposits. Non-interest bearing deposits as a percentage of total deposits was 23% at September 30, 2023 compared to 24% at June 30, 2023 as deposit growth came primarily from interest bearing deposit categories. Net outflows from non-interest bearing deposits stabilized during the third quarter of 2023 as average non-interest bearing deposits during the third quarter of 2023 essentially equaled the amount at the end of the second quarter of 2023 at $10.6 billion.

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 third quarter of 2023, net interest income totaled $462.4 million, an increase of $14.8 million as compared to the second quarter of 2023. The $14.8 million increase in net interest income in the third quarter of 2023 compared to the second quarter of 2023 was primarily due to a $1.6 billion increase in average earning assets and one additional day in the quarter.

Net interest margin was 3.60% (3.62% on a fully taxable-equivalent basis, non-GAAP) during the third quarter of 2023 compared to 3.64% (3.66% on a fully taxable-equivalent basis, non-GAAP) during the second quarter of 2023. The net interest margin decrease as compared to the second quarter of 2023 was primarily due to the negative impact of hedging activities as well as a 36 basis point increase in the rate paid on interest-bearing liabilities. This decrease was partially offset by a 27 basis point increase in yield on earning assets and a five basis point increase in the net free funds contribution. The 36 basis point increase on the rate paid on interest-bearing liabilities in the third quarter of 2023 as compared to the second quarter of 2023 was primarily due to a 41 basis point increase in the rate paid on interest-bearing deposits primarily related to the increasing rate environment. The 27 basis point increase in the yield on earning assets in the third quarter of 2023 as compared to the second quarter of 2023 was primarily due to a 28 basis point expansion on loan yields and 41 basis point increase in liquidity management asset yield.

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

ASSET QUALITY

The allowance for credit losses totaled $399.5 million as of September 30, 2023, an increase of $11.7 million as compared to $387.8 million as of June 30, 2023. A provision for credit losses totaling $19.9 million was recorded for the third quarter of 2023 as compared to $28.5 million recorded in the second quarter of 2023. 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 Current Expected Credit Losses (“CECL”) 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 September 30, 2023, June 30, 2023, and March 31, 2023 is shown on Table 12 of this report.

Net charge-offs totaled $8.1 million in the third quarter of 2023, as compared to $17.0 million of net charge-offs in the second quarter of 2023. The decrease in net charge-offs during the third quarter of 2023 was primarily the result of the sale to external parties of certain credits within the commercial real estate portfolio during the second quarter of 2023, which resulted in approximately $8.0 million in charge-offs. Net charge-offs as a percentage of average total loans were eight basis points in the third quarter of 2023 on an annualized basis compared to 17 basis points on an annualized basis in the second quarter of 2023. For more information regarding net charge-offs, see Table 10 in this report.

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

Non-performing assets totaled $147.2 million and comprised 0.26% of total assets as of September 30, 2023, as compared to $120.3 million as of June 30, 2023. Non-performing loans totaled $133.1 million, or 0.32% of total loans, at September 30, 2023. The increase in the third quarter was primarily due to an increase in loans 90 days or more past due but still fully collateralized within the life insurance premium finance receivables portfolio, and certain credits within the property and casualty insurance premium finance receivables portfolio becoming nonaccrual. For more information regarding non-performing assets, see Table 14 in this report.

NON-INTEREST INCOME

Wealth management revenue was relatively stable in the third quarter of 2023 as compared to the second quarter of 2023. 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 decreased by $2.6 million in the third quarter of 2023 as compared to the second quarter of 2023 primarily due to an unfavorable valuation related change in 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. This was partially offset by increased production revenue and a more favorable adjustments to the fair value of mortgage servicing rights compared to the second 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 $2.4 million in net losses on investment securities in the third quarter of 2023 as compared to nominal gains in the second quarter of 2023.

Fees from covered call options increased by $1.6 million in the third quarter of 2023 as compared to the second quarter of 2023. The Company has typically written call options with terms of less than three months against certain U.S. Treasury and agency securities held in its portfolio for liquidity and other purposes. Management has entered into these transactions with the goal of economically hedging security positions and enhancing its overall return on its investment portfolio. These option transactions are designed to mitigate overall interest rate risk and do not qualify as hedges pursuant to accounting guidance.

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

NON-INTEREST EXPENSE

Salaries and employee benefits expense increased by $7.4 million in the third quarter of 2023 as compared to the second quarter of 2023. The $7.4 million increase is primarily related to higher salary expense and incentive compensation expense due to elevated bonus accruals in the third quarter of 2023 as well as other salary costs of approximately $1.6 million related to acquisition-related severance charges and other contractually due compensation costs.

Operating lease equipment cost increased $2.2 million in the third quarter of 2023 as compared to the second quarter of 2023 primarily due to the impairment of certain assets during the period.

Occupancy expenses increased $2.1 million in the third quarter of 2023 as compared to the second quarter of 2023 primarily due to the impairment of two Company-owned buildings that are no longer being used.

Data processing expense increased $1.0 million in the third quarter of 2023 as compared to the second quarter of 2023 primarily due to the termination of a duplicate service contract related to the acquisition of a wealth management business in 2023.

Lending expenses, net of deferred origination costs, decreased by $3.1 million as compared to the second quarter of 2023 primarily due to higher loan originations in the second quarter of 2023.

Miscellaneous expense in the third quarter of 2023 decreased by $1.0 million as compared to the second quarter of 2023. Miscellaneous expense includes ATM expenses, correspondent bank charges, directors’ fees, telephone, postage, corporate insurance, dues and subscriptions, problem loan expenses and other miscellaneous operational losses and costs.

For more information regarding non-interest expense, see Table 16 in this report.

INCOME TAXES

The Company recorded income tax expense of $60.7 million in the third quarter of 2023 compared to $56.7 million in the second quarter of 2023. The effective tax rates were 26.98% in the third quarter of 2023 compared to 26.81% in the second quarter of 2023.

Mortgage banking revenue was $27.4 million for the third quarter of 2023, a decrease of $2.6 million as compared to the second quarter of 2023, primarily due to an unfavorable valuation related change in 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. Service charges on deposit accounts totaled $14.2 million in the third quarter of 2023, an increase of $609,000 as compared to the second quarter of 2023, primarily due to higher fees associated with commercial account activity.

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.

Wealth management revenue totaled $33.5 million in the third quarter of 2023, which was relatively stable compared to the second quarter of 2023. At September 30, 2023, the Company’s wealth management subsidiaries had approximately $44.7 billion of assets under administration, which included $8.3 billion of assets owned by the Company and its subsidiary banks, representing an increase from the $44.5 billion of assets under administration at June 30, 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.

(3)Interest income on tax-advantaged loans, trading securities and investment securities reflects a taxable-equivalent adjustment based on the marginal federal corporate tax rate in effect as of the applicable period.

(4)See Table 17: Supplemental Non-GAAP Financial Measures/Ratios for additional information on this performance measure/ratio.

(5)Other earning assets include brokerage customer receivables and trading account securities.

(6)Loans, net of unearned income, include non-accrual loans.

(7)Interest rate spread is the difference between the yield earned on earning assets and the rate paid on interest-bearing liabilities.

(8)Net free funds are the difference between total average earning assets and total average interest-bearing liabilities. The estimated contribution to net interest margin from net free funds is calculated using the rate paid for total interest-bearing liabilities.

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. 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
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)
Dec 31, 2022	7.2		3.8		(5.0)		(12.1)
Sep 30, 2022	12.9		7.1		(8.7)		(18.9)


Ramp Scenario	+200 Basis Points		+100 Basis Points		-100 Basis Points		-200 Basis Points
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)
Dec 31, 2022	5.6		3.0		(2.9)		(6.8)
Sep 30, 2022	6.5		3.6		(3.9)		(8.6)

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 expects to 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 $10.0 billion tied to one-month SOFR and $6.0 billion tied to one-year CMT. The above chart shows:


	Basis Point (bp) Change in

TABLE 17: 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.

The $1.9 million decline is primarily related to $6.3 million of lower compensation expense associated with the mortgage banking operation offset somewhat by higher incentive compensation expense for annual bonus and long-term incentive compensation plans during the third quarter relative to the second quarter. $286.9 $286.9 $280.1 $282.1 $0.0 $180.8 $180.8 $172.8 $170.9 $— $20.9 $20.9 $20.9 $22.0 $20.0 $20.0 $17.7 $18.2 $8.5 $8.5 $11.3 $13.4 $10.8 $10.8 $9.9 $10.0 $45.9 $45.9 $47.5 $47.6 Salaries and Employee Benefits Software and Equipment Occupancy, net Advertising and Marketing Operating Lease Equipment Other Q1 2021 Q2 2021 Q3 2021 Q4 2021 Q1 2022 $4.5 $7.9 $4.8 Lending expenses, net of deferred originations costs Q1 2022 Q4 2022 Q1 2023 Strategic Cost Reductions in the Mortgage Business ($ in Millions) 1 FTE - Full-Time Equivalent Employees 1 ($ in Millions) Update title Decrease Primarily Driven by Incentive Compensation, Lower Loan Origination, and Seasonal Decline in Marketing Efficiency Ratio Improvement Driven by Increased NIM and Lower Expenses $320.6 $7.4 $(3.1) $2.1 $3.1 $330.1 Q2 2023 Non-Interest Expense Salaries and Employee Benefits Lending Expenses, net of deferred originations costs Occupancy Expense All Other Expenses Q3 2023 Non-Interest Expense 1 Extraordinary Items - TBD 1 PENDING ($ in Millions) ($ in Millions) Non-Interest Expense Continue to monitor our expenses and believe they are in line with current Company growth Higher Total Salaries Related to Acquisition-Related Severance Charges and Other Contractually due Compensation Cost ($ in Millions) Increase Primarily Driven by Salaries, Commissions and Incentive Compensation ($ in Millions)

Approximately 80% of the estimated increase is related to: ◦ Additions to existing reserves for unfunded lending-related commitments due to the consideration under CECL of expected utilization by the Company's borrowers over the life of such commitments. ◦ Establishment of reserves for acquired loans which previously considered credit discounts. The Company estimates an insignificant impact at adoption of measuring an allowance for credit losses for other in-scope assets (e.g. held-to-maturity debt securities).

The key drivers of the shift in credit quality mix include: • Risk rating upgrades as a result of improved credit performance. • Increase in pass rated credits was driven by commercial loan growth and higher utilization on existing lines partially offset by decline in PPP Loans.
