Andrea G. Short, President and Chief Executive Officer, commented, “We are pleased to announce that 1st Source had a record second quarter. During the second quarter of 2026, average loans and leases grew $119.93 million, up 1.71% and average deposits grew $236.03 million, up 3.28%, each from the previous quarter. Credit quality improved during the quarter with fewer net charge-offs, a lower provision for credit losses, and a reduction in nonperforming assets compared to the previous quarter. We were also able to preserve our net interest margin and further improve our efficiency ratio during the quarter. The positive income statement performance during the quarter also allowed us to further strengthen our already robust balance sheet position.
“During the second quarter of 2026, we were pleased to learn that 1st Source, for the eighth year in a row, was named to the annual Bank Honor Roll by Keefe, Bruyette & Woods, Inc. (KBW). We were among just 17 U.S. Banks on the list, placing our long-term performance among the top 5% of eligible banks in the United States. To be eligible, Banks must have more than $500 million in total assets and meet at least one of two criteria: consistent earnings growth over each of the past 10 years, and/or rank in the top 5% of eligible banks based on a 10-year earnings per share (EPS) compounded annual growth rate (CAGR). This recognition reinforces that our mission of Helping Clients Achieve Security, Build Wealth And Realize Their Dreams® aligns with consistent, strong financial performance for the long term.
“Additionally, we learned that we once again received both Forbes’ America’s Best-In-State Banks and Forbes’ America’s Best Employers for New Grads. According to Forbes, the Best-In-State ranking is based on an independent survey of approximately 26,000 U.S. residents who evaluated their primary banking relationships across key dimensions including trust, customer service, financial advice, digital experience, and overall satisfaction. For the Best Employers for New Grads, Forbes surveyed more than 100,000 young professionals working for companies with at least 1,000 employees in the U.S., asking them to evaluate employers in areas such as salary, benefits, advancement opportunities, AI adoption, work-life balance and company image. We are proud of these awards, which highlight that our culture and values are evident to both our clients and our colleagues.
“We are also excited to have recently celebrated the groundbreaking ceremony for our newest location in West Lafayette. This will be our third location in the Lafayette area and the banking center will feature our side-by-side banking model which invites the client behind the “teller line,” allowing our clients and bankers to have a more transparent and inclusive experience and relationship. We are excited to watch the construction process and look forward to serving personal and business clients in this new location with our full suite of services soon.” Mrs. Short concluded.

SECOND QUARTER 2026 FINANCIAL RESULTS
Loans and Leases
Second quarter average loans and leases were $7.14 billion, which was up $119.93 million or 1.71% from the previous quarter and increased $174.23 million or 2.50% from the second quarter of 2025. Year-to-date average loans and leases increased $198.88 million, up 2.89% from the first six months of 2025. Average loan growth in the second quarter of 2026 occurred mainly within the Commercial and Agricultural, Renewable Energy, Construction Equipment, and Commercial Real Estate portfolios.
Deposits
Second quarter average deposits were $7.43 billion, which was up $236.03 million or 3.28%, from the previous quarter and increased $78.52 million or 1.07% compared to the second quarter a year ago. Average deposits for the first six months of 2026 were $7.31 billion, a decrease of $31.12 million or 0.42% from the same period a year ago. Average deposit balances increased from the previous quarter primarily due to higher interest-bearing demand deposits which included seasonal increases associated with municipal tax collection cycles, time deposits, and savings deposits. Average brokered deposits were $301.08 million, an increase of $41.79 million or 16.12% compared to the previous quarter and a decrease of $181.34 million or 37.59% from the prior year second quarter.
Net Interest Income and Net Interest Margin
Second quarter 2026 tax-equivalent net interest income increased $3.00 million to $93.30 million, up 3.33% from the previous quarter and was $7.95 million, or 9.32% higher compared to the second quarter a year ago. For the first six months of 2026, tax equivalent net interest income increased $17.16 million to $183.59 million, up 10.31% from the first half of 2025.
- 2 -


Second quarter 2026 net interest margin was 4.23%, a decrease of one basis point from 4.24% in the previous quarter and an increase of 23 basis points from the same period in 2025. On a fully tax-equivalent basis, the second quarter 2026 net interest margin was 4.24%, down one basis point from the previous quarter and an increase of 23 basis points from the same period in 2025. The increase from the second quarter of 2025 was primarily due to higher average loan and lease balances, improved yields on investments from portfolio repositioning trades made in 2025, and lower interest-bearing deposit costs. Net interest recoveries had a positive three basis points impact during the quarter on the tax-equivalent net interest margin, compared to a positive one basis point in the previous quarter and net interest charge-offs had no impact in the prior year’s second quarter.
Net interest margin and net interest margin on a fully-tax equivalent basis for the first six months of 2026 were 4.24%, an increase of 29 basis points compared to 3.95% for the first six months of 2025. Net interest recoveries had a positive one basis point impact and three basis points positive impact to the current and previous year-to-date fully tax-equivalent net interest margin.
Noninterest Income
Second quarter 2026 noninterest income of $25.02 million increased $2.02 million or 8.77% compared to the previous quarter and was higher by $1.96 million or 8.51% compared to the second quarter a year ago. For the first six months of 2026, noninterest income increased $1.86 million or 4.03% from the first six months of 2025.
The increase from the previous quarter was mainly due to higher trust and wealth advisory income from larger than usual estate administration fees primarily from one account in the process of settlement and seasonal tax preparation fees, an increase in debit card income, higher brokerage fees and commissions, higher interest rate swap fees, and increased partnership investment gains. These increases were offset by lower insurance contingent commissions and decreased mortgage banking income from lower sales volumes.
The increase in noninterest income compared to the second quarter and first six months of 2025 was the result of increased trust and wealth advisory income from larger than usual estate administration fees mentioned above, realized losses of $1.00 million from repositioning of available-for-sale securities during the second quarter of 2025, increased deposit account fees, higher debit card income, and a rise in brokerage commissions and fees. These increases were offset by fewer gains on the sale of renewable energy tax equity investments, reduced equipment rental income as demand for operating leases continued to decline and decreased mortgage banking income from lower gains on loan sales due to reduced profit margins.
Noninterest Expense
Second quarter 2026 noninterest expense of $55.03 million increased $0.51 million or 0.93% compared to the prior quarter and rose $2.60 million or 4.95% from the second quarter a year ago. For the first six months of 2026, noninterest expense increased $4.04 million, or 3.83% from the first six months of 2025.
The increase in noninterest expense compared to the second quarter and first six months of 2025 was the result of increased salaries and wages due to normal merit increases, increased incentive compensation and higher group insurance claims. Additionally, we saw increased occupancy expenses from snow removal during the first quarter and premises repairs, higher professional consulting costs, a rise in collection and repossession expense, and an increase in debit card losses. These increases were offset by lower leased equipment depreciation and an increase in gains on the sale of repossessed assets.
Credit
The allowance for loan and lease losses increased to $166.35 million as of June 30, 2026, or 2.30% of total loans and leases. The 2.30% decreased from 2.33% at March 31, 2026 and remained consistent with the 2.30% at June 30, 2025. Net charge-offs of $0.52 million were recorded for the second quarter of 2026, compared with net charge-offs of $3.96 million in the prior quarter and net charge-offs of $1.87 million in the same quarter a year ago.
- 3 -


The provision for credit losses was $1.54 million for the second quarter of 2026, a decrease of $5.73 million from the previous quarter and a decrease of $6.15 million compared with the same period in 2025. The decrease in the provision expense was mainly due to a reduction in special attention loans, reduced net charge-offs and a decrease in the provision for unfunded commitments due to increased line utilization and loan fundings, offset by loan growth. The ratio of nonperforming assets to loans and leases was 1.01% as of June 30, 2026, compared to 1.03% on March 31, 2026 and 1.06% on June 30, 2025. The decrease in nonperforming assets during the quarter was primarily from lower nonaccrual loans and leases partially offset by an increase in repossessed assets.
Capital
As of June 30, 2026, the common equity-to-assets ratio was 14.15%, compared to 14.02% at March 31, 2026 and 13.19% a year ago. The tangible common equity-to-tangible assets ratio was 13.36% at June 30, 2026, compared to 13.22% at March 31, 2026 and 12.38% a year earlier. The Common Equity Tier 1 ratio, calculated under banking regulatory guidelines, was 15.49% at June 30, 2026, compared to 15.30% at March 31, 2026 and 14.60% a year ago. There were no shares repurchased for treasury during the second quarter of 2026. Total year-to-date repurchased shares of 338,356 have reduced common shareholders equity by $23.35 million.

NON-GAAP FINANCIAL MEASURES
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 with 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.
See the table marked “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of certain non-GAAP financial measures used by the Company with their most closely related GAAP measures.
