Christopher J. Murphy III, Chairman and Chief Executive Officer, commented, “We are pleased that the strong start in 2023 continued throughout the second quarter. In the second quarter of 2023, average loans grew $104.95 million, up 1.74% while average deposits grew $70.08 million, up 1.02% from the previous quarter. Credit quality during the quarter remained steady with low levels of nonperforming assets. Our liquidity position is solid, our strong capital position continued, and deposit balances increased modestly during the period from expected seasonal trends. The tax-equivalent net interest margin continues to be under pressure at 3.48%, down 12 basis points from the prior quarter, as rate competition on deposits remains elevated.

“We were incredibly pleased to learn during the second quarter that 1st Source was included on the Forbes ‘Best In State Banks’ list, ranking #1 in Indiana! The list was compiled in partnership with market research firm Statista, and the result of an independent survey conducted of bank customers across the state. Being named among the ‘Best In State Banks’ in Indiana by our clients for the second consecutive year, and #1 in the state for the first time, is an important and gratifying recognition for us. We strive every day to show our clients they have made the right choice for their financial future by entrusting us to be their partner. Being named the best bank in Indiana by our clients lets us know that we are living our mission to help people achieve security, build wealth and realize their dreams in all that we do.

“We were also happy to learn that 1st Source was named among the Keefe, Bruyette & Woods, Inc. (KBW) Bank Honor Roll for the fifth consecutive year. We are proud to be one of the 14 honorees, placing us among the top 4% of eligible banks in the country. To be considered for this recognition, banks must be publicly traded institutions with more than $500 million in total assets and must have had 10 consecutive years of increased earnings per share. We strive to strike the right balance in our performance over the longer term and the ways we deliver positive results for our clients, shareholders, colleagues and communities. Receiving this honor once again is welcome recognition that our efforts are successful.

“As part of a strategic initiative to grow our commercial banking footprint and refocus the efforts of some of our leadership team, two significant changes were made this quarter as well. The first being, we opened a loan production office in the Indianapolis area, currently open by appointment only, which serves the community with small business loans and other commercial credit needs. The team will grow over time, and we look forward to serving business clients in this market. It was also announced that Larry Mayers, who has long served as Fort Wayne Regional President and Business Banking Group Head, would step away from his regional duties to focus solely on his business banking responsibilities. Luke Squires was named as his successor, taking over the role of Regional President of the Fort Wayne region and Cecile Weir replaced Luke as head of Business Banking in Fort Wayne. These changes align with 1st Source Bank’s community banking model. They continue our tradition of promoting from within and enhance our position as a community bank with a strong client focus and local leaders who strongly live the 1st Source values and who have the authority and responsibility to serve clients well and grow the Bank.

“We announced in April the re-election of three board members – Christopher J. Murphy III, Chairman, President and Chief Executive Officer of 1st Source Corporation and Chairman of 1st Source Bank; Timothy K. Ozark, Chairman, TKO Finance Corporation; and Todd F. Schurz, Former President and Chief Executive Officer, Schurz Communications, Inc. – and the election of Andrea G. Short, President and Chief Executive Officer of 1st Source Bank as a new addition to the 1st Source Corporation Board of Directors. They all bring unique and valuable perspective to the Board and are knowledgeable business leaders with passion for 1st Source’s mission, making them ideal stewards for the future of the Company.

“Lastly, I must mention, after the quarter ended, just last week, we lost a friend, a partner, and a leader in the Bank and the community when Ernestine Raclin, our Chairman Emeritus died at the age of 95. The community joined us in celebrating her life and we acknowledge here the role she played in establishing the vision of who we are today - focusing on our Mission and living our values. Her legacy will live on in the way we serve our clients, and communities for generations to come.

I thank you all for the outpouring of condolences and the messages celebrating her spirit. She loved this organization and the people here so dearly, and we’ll all miss her and honor her well into the future,” Mr. Murphy concluded.

Second quarter average loans and leases increased $104.95 million to $6.14 billion, up 1.74% from the previous quarter and increased $673.35 million, up 12.31% from the year ago second quarter. Year-to-date average loans and leases increased $692.50 million to $6.09 billion, up 12.83% from the first six months of 2022. Growth during the quarter occurred primarily within the Auto and Light Truck, Construction Equipment, and Commercial Real Estate portfolios.

The Company has traditionally maintained a conservative approach to commercial real estate loans and non-owner occupied properties. At June 30, 2023, approximately 5% of the Company’s total loans and leases are collateralized by non-owner occupied commercial real estate. The Company finances a minimal amount of commercial real estate secured by non-owner occupied office property where third-party tenant rents are the primary source of repayment. All non-owner occupied commercial real estate office projects are performing as agreed.

Average deposits of $6.94 billion, grew $70.08 million, up 1.02% from the previous quarter and grew $143.29 million or 2.11% compared to the quarter ended June 30, 2022. Average deposits for the first six months of 2023 were $6.90 billion, an increase of $197.41 million, up 2.94% from the same period a year ago. Average balances were modestly higher primarily due to expected seasonal public fund deposit inflows during the quarter.

End of period deposits were $6.98 billion at June 30, 2023, compared to $6.80 billion at March 31, 2023. Balances were higher primarily due to higher public funds, time, and brokered deposits which were offset by a decrease in noninterest-bearing deposits and a slight decrease in savings account 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 2023 tax-equivalent net interest income declined $1.10 million to $68.70 million, down 1.57% from the previous quarter and increased $5.11 million, up 8.04% from the second quarter a year ago. For the first six months of 2023, tax-equivalent net interest income increased $15.18 million to $138.49 million, up 12.31% from the first half of 2022.

Second quarter 2023 net interest margin was 3.47%, a decline of 12 basis points from the 3.59% in the previous quarter and an increase of 16 basis points from the same period in 2022. On a fully tax-equivalent basis, second quarter 2023 net interest margin was 3.48%, down by 12 basis points compared to the 3.60% in the previous quarter and an increase of 16 basis points from the same period in 2022. The 12-basis point decrease from the prior quarter was primarily due to higher rates on interest-bearing deposits mainly from competitive market pressures and increased borrowing rates. Higher market rates due to multiple Federal Reserve rate increases during 2022 and 2023 contributed to net interest margin expansion compared to the previous year’s second quarter.

Net interest margin for the first six months of 2023 was 3.53%, an increase of 29 basis points compared to the first six months of 2022. Similarly, net interest margin on a fully-tax-equivalent basis for the first half of 2023 was 3.54%, an increase of 29 basis points compared to the first half of the prior year.

Second quarter 2023 noninterest income decreased $0.55 million to $22.77 million, down 2.38% from the previous quarter and was relatively flat compared to the second quarter a year ago. For the first six months of 2023, noninterest income held steady from the same period a year ago.

The decrease in noninterest income compared to the previous quarter was due to gains on the sale of renewable energy tax equity investments of $1.11 million during the previous quarter. These were offset by higher seasonal tax preparation fee income recognized in the second quarter of 2023 from our Trust and Wealth Advisory Services Group.

Second quarter 2023 noninterest expense of $49.17 million was relatively flat from the prior quarter and increased $3.51 million, or 7.69% from the second quarter a year ago. For the first six months of 2023, noninterest expense was $98.59 million, an increase of $7.60 million, or 8.35% from the same period a year ago.

The increase in noninterest expense for the second quarter and first six months of 2023 was mainly the result of higher salaries from normal merit increases, the impact of wage inflation and an increase in the number of employees due to fewer open positions. A rise in group insurance claims, increased data processing and technology project costs, and higher FDIC insurance premiums also contributed to higher expenses. These were offset by a $1.08 million reversal of accrued legal fees during the first quarter of 2023 and lower leased equipment depreciation.

The allowance for loan and lease losses as of June 30, 2023, was 2.31% of total loans and leases compared to 2.33% at March 31, 2023, and 2.39% at June 30, 2022. Net recoveries of $0.98 million were recorded for the second quarter of 2023 compared with $0.19 million of net recoveries in the prior quarter and net recoveries of $0.40 million in the same quarter a year ago.

The provision for credit losses was $0.05 million for the second quarter of 2023, a decrease of $3.00 million from the previous quarter and a decrease of $2.46 million compared with the same period in 2022. The decrease in provision for credit losses compared to the previous quarter was primarily due to increased net recoveries and a reduction in highly reserved special attention loan balances. The ratio of nonperforming assets to loans and leases was 0.33% as of June 30, 2023, compared to 0.30% on March 31, 2023, and 0.60% on June 30, 2022.

As of June 30, 2023, the common equity-to-assets ratio was 10.95%, compared to 10.91% at March 31, 2023, and 10.66% a year ago. The tangible common equity-to-tangible assets ratio was 10.05% at June 30, 2023, compared to 10.01% at March 31, 2023, and 9.72% a year earlier. The Common Equity Tier 1 ratio, calculated under banking regulatory guidelines was 13.59% at June 30, 2023 compared to 13.51% at March 31, 2023 and 13.79% a year ago. During the second quarter of 2023, 33,276 shares were repurchased for treasury reducing common shareholders’ equity by $1.41 million.

The Company has a long history of maintaining conservative capital levels and the risk-based capital ratios remained strong during the second quarter, even when adjusting for unrealized losses on the available-for-sale securities portfolio.

The Company maintains prudent strategies to support a strong liquidity position. Sources of liquidity include unencumbered available-for-sale securities, Federal Home Loan Bank (FHLB) advances, the Federal Reserve Bank (FRB) discount window and Bank Term Funding Program, Federal Funds lines from correspondent banks and brokered and listing services deposits. Total net available liquidity was $3.23 billion at June 30, 2023, which accounted for approximately 50% of total deposits net of brokered and listing services certificates of deposit.

The investment portfolio is managed with a prioritized focus on liquidity. Investment securities accounted for 19.74% of total assets at June 30, 2023, with the entirety of the portfolio classified as available-for-sale. The Company had no held-to-maturity securities therefore all market value adjustments resulting in unrealized gains and losses were reflected on the Consolidated Statements of Financial Condition. The modified duration of the total investment portfolio was calculated at 3.3 years.

Those statements, including statements, projections, estimates or assumptions concerning future events or performance, and other statements that are other than statements of historical fact, are subject to material risks and uncertainties. 1st Source cautions readers not to place undue reliance on any forward-looking statements, which speak only as of the date made.

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.
