South Bend, IN - 1st Source Corporation (NASDAQ: SRCE), parent company of 1st Source Bank, today reported record quarterly net income of $36.79 million for the second quarter of 2024, up $7.34 million or 24.91% from the previous quarter and up 13.44% from the $32.44 million reported in the second quarter a year ago. Year-to-date 2024 net income was $66.25 million compared to $63.56 million during the first six months of 2023. Diluted net income per common share for the second quarter of 2024 was $1.49, up $0.30 or 25.21% from the previous quarter and up 14.62%, versus $1.30 in the second quarter of 2023. Diluted net income per common share for the first half of 2024 was $2.68 compared to $2.55 a year earlier.

At its July 2024 meeting, the Board of Directors approved an increase in the cash dividend of two cents per share, raising the approved dividend for the quarter to $0.36 per common share, up 12.50% from the cash dividend declared a year ago.

Christopher J. Murphy III, Chairman and Chief Executive Officer, commented, “We are very pleased to have achieved record quarterly earnings during the second quarter. Average loans and leases grew $102.14 million, up 1.57%, and average deposits increased $172.53 million, or 2.46% compared to the previous quarter. Disciplined loan and lease pricing led to an improvement in our net interest margin of five basis points from the prior quarter. This marks the third consecutive quarter of margin expansion despite persistent deposit rate competition. We were also helped by net recoveries of $1.99 million during the quarter. Nonperforming assets to loans and leases at June 30, 2024, was 0.31%, down from 0.34% at March 31, 2024, and the allowance for loan and lease losses as a percentage of total loans and leases remained strong and unchanged from the previous quarter at 2.26%. Additionally, our liquidity and capital positions remained strong.

“During the quarter, we were excited to learn that 1st Source was named by Forbes’ as one of America’s Best Banks! We ranked #14 on the list and the only bank in Indiana to be in the top 15. This award is a proof point that we are holding true to our long-standing commitment of helping our clients achieve security, build wealth, and realize their dreams by building a fortress-like balance sheet and quality, sustainable earnings to help us better serve them!

“The proof points continued to roll in this quarter as we also were named to the Forbes’ Best in State Banks and Best Employers for New Grads lists. Finally, US News & World Report recently announced that 1st Source Bank was named a “Best Company to Work For” in the Midwest. It is an honor to receive this blend of awards because it emphasizes our stability as a bank not only financially, but also culturally.

“We strive to provide our colleagues with an engaging work environment that upholds our core values of integrity, teamwork, and superior quality paired with outstanding client service and community leadership. In keeping with our commitment to our community, we have remodeled both our Dunlap and our Bristol Street Banking Centers to feature our side-by-side banking model. This experience invites clients behind the teller line, allowing for clients and bankers to have a more transparent and inclusive relationship.”, Mr. Murphy concluded.

Second quarter average loans and leases increased $102.14 million to $6.61 billion, up 1.57% from the previous quarter and increased $465.05 million, up 7.57% from the second quarter a year ago. Year-to-date average loans and leases increased $466.17 million to $6.56 billion, up 7.66% from the first six months of 2023. Growth during the quarter occurred primarily within the Construction Equipment, Renewable Energy and Auto and Light Truck portfolios.

Average deposits of $7.18 billion, increased $172.57 million, or 2.46% from the previous quarter, and grew $244.60 million or 3.52% compared to the quarter ended June 30, 2023. Average deposits for the first six months of 2024 were $7.10 billion, an increase of $193.15 million, up 2.80% from the same period a year ago. Average deposit balance growth from the previous quarter was primarily due to expected seasonal public fund deposit inflows. Average deposit balance growth from the second quarter of 2023 was primarily in savings, time, and brokered deposits.

End of period deposits were $7.20 billion at June 30, 2024, compared to $7.06 billion at March 31, 2024. Balances were higher mainly due to increased public fund deposits and time deposits, offset by decreased noninterest bearing deposits and brokered deposits. Rate competition for deposits persisted during the quarter from various areas including traditional bank and credit union competitors, money market funds, bond markets, and other non-bank alternatives.

Second quarter 2024 tax-equivalent net interest income increased $2.13 million to $74.19 million, up 2.96% from the previous quarter and increased $5.50 million, up 8.00% from the second quarter a year ago. For the first six months of 2024, tax equivalent net interest income increased $7.77 million to $146.26 million, up 5.61% from the first half of 2023.

Second quarter 2024 net interest margin was 3.59%, an increase of five basis points from the 3.54% in the previous quarter and an increase of 12 basis points from the same period in 2023. On a fully tax-equivalent basis, second quarter 2024 net interest margin was 3.59%, up by five basis points compared to the 3.54% in the previous quarter, and an increase of 11 basis points from the same period in 2023. The five basis point increase from the prior quarter was primarily due to higher rates on loan and lease balances and less reliance on higher costing short-term borrowings.

Net interest margin for the first six months of 2024 was 3.56%, an increase of three basis points compared to the first six months of 2023. Net interest margin on a fully-tax equivalent basis for the first half of 2024 was 3.57%, an increase of three basis points compared to the first half of the prior year.

Second quarter 2024 noninterest income of $23.22 million increased $1.07 million, up 4.81% from the previous quarter, and was up modestly compared to the second quarter a year ago. For the first six months of 2024, noninterest income decreased slightly from the same period a year ago.

The increase in noninterest income compared to the previous quarter was mainly due to higher trust and wealth advisory income primarily from seasonal tax preparation fee income and improvements in overall investment market performance. Additionally, increased debit card income, and a rise in mortgage banking income from higher sales volumes were offset by lower equipment rental income due to a change in customer preferences and continued competitive pricing pressure for new business.

Second quarter 2024 noninterest expense of $49.49 million was relatively flat compared to the prior quarter and increased slightly from the second quarter a year ago. For the first six months of 2024, noninterest expense was $99.08 million, up marginally from the same period a year ago.

The increase in noninterest expense compared to the second quarter and first six months of 2023 was the result of higher salaries and wages from normal merit increases, the impact of wage inflation and an increase in the number of employees filling prior open positions and a $1.08 million reversal of accrued legal fees during the first quarter of 2023. Additionally, increased data processing costs from technology projects, higher blanket bond insurance premium costs, as well as an increase in business development and marketing expenses, added to the increase. These increases were offset by reduced group insurance claims, lower leased equipment depreciation, a decrease in the loan loss provision for unfunded commitments and gains on the sale of leased equipment.

The allowance for loan and lease losses of $150.07 million as of June 30, 2024, was 2.26% of total loans and leases. This percentage compared to 2.26% at March 31, 2024, and 2.31% at June 30, 2023. Net recoveries of $1.99 million were recorded for the second quarter of 2024, compared with $6.12 million of net charge-offs in the prior quarter and net recoveries of $0.98 million in the same quarter a year ago. The majority of the second quarter’s recoveries were related to activity in our Construction, Auto and Light Truck and Aircraft portfolios.

The provision for credit losses was $0.06 million for the second quarter of 2024, a decrease of $6.54 million from the previous quarter and an increase of $0.01 million compared with the same period in 2023. Net recoveries recorded during the quarter, compared to net charge-offs in the previous quarter, were the primary reason for the decrease in the provision for credit losses. The provision for credit losses during the quarter was driven by modest loan growth, an increase in specific impairments, and overall higher special attention outstandings, offset by a decrease in aircraft portfolio loan balances which carry a higher allowance due to historical risk volatility. The ratio of nonperforming assets to loans and leases was 0.31% as of June 30, 2024, compared to 0.34% on March 31, 2024, and 0.33% on June 30, 2023.

As of June 30, 2024, the common equity-to-assets ratio was 11.75%, compared to 11.65% at March 31, 2024, and 10.95% a year ago. The tangible common equity-to-tangible assets ratio was 10.91% at June 30, 2024, compared to 10.79% at March 31, 2024, and 10.05% a year earlier. The Common Equity Tier 1 ratio, calculated under banking regulatory guidelines was 13.74% at June 30, 2024 compared to 13.48% at March 31, 2024 and 13.59% a year ago.
Capital accretion over the last twelve months has been driven primarily by growth in retained earnings and a reduction in unrealized losses in our short-duration investment securities available-for-sale portfolio.

No shares were repurchased for treasury during the second quarter of 2024.

1st Source may make other written or oral forward-looking statements from time to time. Readers are advised that various important factors could cause 1st Source’s actual results or circumstances for future periods to differ materially from those anticipated or projected in such forward-looking statements. Such factors, among others, include changes in laws, regulations or accounting principles generally accepted in the United States; 1st Source’s competitive position within its markets served; increasing consolidation within the banking industry; unforeseen changes in interest rates; unforeseen downturns in the local, regional or national economies or in the industries in which 1st Source has credit concentrations; and other risks discussed in 1st Source’s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K, which filings are available from the SEC. 1st Source undertakes no obligation to publicly update or revise any forward-looking statements.

The accounting and reporting policies of 1st Source conform to generally accepted accounting principles (“GAAP”) in the United States and prevailing practices in the banking industry. However, certain non-GAAP performance measures are used by management to evaluate and measure the Company’s performance. Although these non-GAAP financial measures are frequently used by investors to evaluate a financial institution, they have limitations as analytical tools, and should not be considered in isolation, or as a substitute for analyses of results as reported under GAAP. These include taxable-equivalent net interest income (including its individual components), net interest margin (including its individual components), the efficiency ratio, tangible common equity-to-tangible assets ratio and tangible book value per common share. Management believes that these measures provide users of the Company’s financial information a more meaningful view of the performance of the interest-earning assets and interest-bearing liabilities and of the Company’s operating efficiency. Other financial holding companies may define or calculate these measures 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 (“FTE”) basis. In this non-GAAP presentation, net interest income is adjusted to reflect tax-exempt interest income on an equivalent before-tax basis. 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 and lease depreciation), measures how much it costs to produce one dollar of revenue. Securities gains or losses and lease depreciation are excluded from this calculation to better match revenue from daily operations to operational expenses. Management considers the tangible common equity-to-tangible assets ratio and tangible book value per common share as useful measurements of the Company’s equity.
