CEO/President Commentary

Roberto R. Herencia, Executive Chairman and CEO of Byline Bancorp, commented, "Our third quarter performance reflects Byline's continued strong momentum across the franchise as we posted strong results. We are excited about our pending First Security Bancorp, Inc. transaction, which aligns with our long-term M&A strategy. We believe this merger strengthens our position in the market by adding a high-quality franchise with a strong core deposit base. We look forward to welcoming First Security Bank and Trust customers to Byline in 2025."

Alberto J. Paracchini, President of Byline Bancorp, added, "Third quarter results were highlighted by robust earnings, strong profitability, net interest income expansion, solid deposit and fee revenue growth, and controlled non-interest expense. Importantly, we increased tangible book value and continue to maintain excellent balance sheet strength. We remain focused on executing our strategy of becoming the preeminent commercial bank in Chicago while continuing to increase the value of the franchise."

Board Declares Cash Dividend of $0.09 per Share

On October 22, 2024, the Company's Board of Directors declared a cash dividend of $0.09 per share, payable on November 19, 2024, to stockholders of record of the Company's common stock as of November 5, 2024.

STATEMENTS OF OPERATIONS HIGHLIGHTS

Net Interest Income

Net interest income for the third quarter of 2024 was $87.5 million, an increase of $929,000, or 1.1%, from the second quarter of 2024. The increase in net interest income was primarily due to increases in other interest and dividend income driven by increased interest income on funds held with the Federal Reserve Bank, and increases in interest and fees on loans and leases mainly due to day count. These were offset by increases in interest expense on deposits primarily due to increased average balances in time deposits and money market accounts from our deposit promotion campaigns.

Tax-equivalent net interest margin⁽¹⁾ for the third quarter of 2024 was 3.89%, a decrease of ten basis points compared to the second quarter of 2024. Net loan accretion income positively contributed 13 basis points to the net interest margin for the current quarter compared to 17 basis points for the prior quarter.

The average cost of total deposits was 2.76% for the third quarter of 2024, an increase of 13 basis points compared to the second quarter of 2024, as a result of higher rates paid on time deposits. Average non-interest-bearing demand deposits were 23.2% of average total deposits for the current quarter compared to 25.0% during the prior quarter.

Provision for Credit Losses

The provision for credit losses was $7.5 million for the third quarter of 2024, an increase of $1.4 million compared to $6.0 million for the second quarter of 2024, mainly attributed to increases related to individually assessed loans in the government guaranteed loan portfolio. The provision for credit losses for the quarter is comprised of a provision for loan and lease losses of $7.6 million compared to $6.9 million in the second quarter of 2024, and a recapture of the provision for unfunded commitments of $122,000 compared to $833,000 in the second quarter of 2024.

Non-interest Income

Non-interest income for the third quarter of 2024 was $14.4 million, an increase of $1.5 million, or 12.0%, compared to $12.8 million for the second quarter of 2024. The increase in total non-interest income was primarily due to the change in the fair value of equity securities, net, and an increase in other non-interest income due to increased swap fee activity.

Net gains on sales of loans were $5.9 million for the current quarter, a decrease of $172,000, or 2.8% compared to the prior quarter. During the third quarter of 2024, we sold $79.5 million of U.S. government guaranteed loans compared to $73.9 million during the second quarter of 2024.

Non-interest Expense

Non-interest expense for the third quarter of 2024 was $54.3 million, an increase of $1.1 million, or 2.1%, compared to $53.2 million for the second quarter of 2024. The increase in non-interest expense was mainly due to increased salaries and employee benefits as a result of one additional payroll day, higher commissions, and lower deferred salaries related to loan and lease originations. Included in legal, audit and other professionals fees are $408,000 in merger-related expenses, and $3,000 merger-related expenses in data processing.

Our efficiency ratio was 52.02% for the third quarter of 2024 compared to 52.19% for the second quarter of 2024, a decrease of 17 basis points. Our adjusted efficiency ratio was 51.62%⁽¹⁾ for the third quarter of 2024 compared to 52.19%⁽¹⁾ for the second quarter of 2024, a decrease of 57 basis points.

Income Taxes

We recorded income tax expense of $9.7 million during the third quarter of 2024, compared to $10.4 million during the second quarter of 2024. The effective tax rates were 24.3% and 26.0% for the third quarter of 2024 and second quarter of 2024, respectively. The decrease in the effective tax rate was due to higher income tax benefits related to share-based compensation recorded in the third quarter.

STATEMENTS OF FINANCIAL CONDITION HIGHLIGHTS

Assets

Total assets were $9.4 billion as of September 30, 2024, a decrease of $209.5 million, or 2.2%, compared to $9.6 billion at June 30, 2024. The decrease was mainly due to a decrease in cash and cash equivalents of $277.9 million, primarily due to the repayment during the quarter of the Bank Term Funding Program advance of $200.0 million, offset by an increase to securities available-for-sale, mainly from purchases of commercial and residential mortgage-backed securities.

Asset and Credit Quality

The ACL was $98.9 million as of September 30, 2024, a decrease of $870,000, or 0.9%, from $99.7 million at June 30, 2024. Net charge-offs of loans and leases during the third quarter of 2024 were $8.5 million, or 0.49% of average loans and leases, on an annualized basis. This was a decrease of $1.0 million compared to net charge-offs of $9.5 million, or 0.56% of average loans and leases, during the second quarter of 2024. The decrease is primarily due to lower charge-offs in the conventional portfolio.

Non-performing assets were $71.0 million, or 0.75% of total assets, as of September 30, 2024, an increase of $6.5 million from $64.6 million, or 0.67% of total assets, at June 30, 2024. The increase was primarily in non-accrual government guaranteed loans. The government guaranteed portion of non-performing loans included in non-performing assets was $11.3 million at September 30, 2024 compared to $6.6 million at June 30, 2024, an increase of $4.7 million.

Deposits and Other Liabilities

Total deposits increased $150.7 million to $7.5 billion at September 30, 2024 compared to $7.3 billion at June 30, 2024. The increase in deposits in the current quarter was mainly due to increases in commercial money market accounts and consumer time deposits.

Total borrowings and other liabilities were $830.1 million at September 30, 2024, a decrease of $423.5 million from $1.3 billion at June 30, 2024, primarily driven by a $200.0 million decrease in Federal Home Loan Bank advances and the repayment of the $200.0 million advance under the Bank Term Funding Program.

Stockholders' Equity

Total stockholders' equity was $1.1 billion at September 30, 2024, an increase of $63.3 million, or 6.1%, from June 30, 2024, primarily due to a decrease in unrealized losses on securities available-for-sale and an increase in retained earnings from net income.
