South Bend, IN - 1st Source Corporation (NASDAQ: SRCE), parent company of 1st Source Bank, today reported net income of $16.41 million for the first quarter of 2020, a decrease of 26.05% compared to $22.20 million reported in the first quarter a year ago. The net income comparison was negatively impacted by an increased provision for loan and lease losses of $6.44 million primarily due to a sizeable impairment on one account, the likely negative economic impact on our portfolio from COVID-19, higher special attention outstandings in the quarter and increased loan and lease balances. Non-recurring 2020 items included $0.45 million in FDIC insurance premium credits received.

Diluted net income per common share for the first quarter of 2020 was down 25.58% to $0.64, versus $0.86 in the first quarter of 2019.

At its April 2020 meeting, the Board of Directors approved a cash dividend of $0.28 per common share, up 3.70% from the $0.27 per common share declared a year ago. The cash dividend is payable to shareholders of record on May 5, 2020 and will be paid on May 15, 2020.

Christopher J. Murphy III, Chairman and Chief Executive Officer, commented, “While this has been a tough quarter, we are pleased that we have been able to help our customers navigate through the uncertainties presented by the current coronavirus (COVID-19) pandemic and we will continue to do so. We are well-positioned for the long term, are well-capitalized, have appropriate reserves, and have a strong balance sheet. That said, the near-term level of uncertainty is unprecedented as to the severity and length of the economic downturn tied to the coronavirus offset possibly by the effectiveness of the government’s enormous stimulus efforts. The continuation of shelter-in-place in our markets for prolonged periods of time, the inability to control the virus, and its possible return in the fall or winter could have serious negative impact on our clients and the markets we serve. In this environment of uncertainty, it is hard to predict what can or will happen and the impact it will have on us.

“As the current pandemic continues to negatively impact the economy, resulting in layoffs and rising unemployment in our local community banking markets and stresses among our specialty finance clients, we are working proactively to support our clients through this difficult period with a heightened sense of purpose and determination to deliver exceptional service to them. To date, we have approved and processed more than $494 million of loan modifications across our loan portfolios. The largest volume of loan modifications has been in the Auto and Light Truck, Construction and Commercial loan portfolios where business operations were directly impacted early-on by the pandemic. In addition, we are participating in the Small Business Administration Paycheck Protection Program (PPP) and have processed 2,061 small business PPP loans totaling more than $554 million to date. The PPP is a loan program designed to help small businesses keep their workforces employed during the coronavirus crisis and is one of a number of stimulus initiatives we have stood up and are delivering to our business and consumer clients. While these are tumultuous times, we will continue our longstanding practice of providing straight talk, sound advice, always keeping our clients’ best interests in mind for the long-term.

“On a more positive note, our residential mortgage loan business has been booming. We are seeing highproduction volumes and profitable results. Prior year Lean initiatives to streamline and hone our mortgage loan processes have allowed us to keep pace with the surging demand.

“In late January, we opened our newly constructed stand-alone banking center in the Middlebury, Ind. community. Our prior location there, where we had been a tenant for many years, was not consistent with the atmosphere our customers have come to know and expect from our banking centers. The new banking center features our signature side-by-side banking experience, as well as drive up teller service lanes and ATM. A few weeks after that, we opened the doors to our new banking center in downtown Auburn, Ind. We entered this community outside Fort Wayne strategically, and we have received a tremendous response from the people and businesses there. We have of course joined with our clients and the communities we serve to adjust the experience in all our banking centers to “flatten the curve” and support our first responders and health-care professionals in this unprecedented global response to an invisible enemy.

“In closing, I’d like to reassure you that 1st Source is committed to the essential work we do in the banking industry and for our clients. We have put many precautions in place so that we may continue to serve our clients through this difficult time while also ensuring their health and well-being as well as the health and well-being of our employees and all of our families and the communities we serve. Teams have been split up so that infection cannot spread across entire departments, disrupting the important work our employees do. We are encouraging virtual meetings and conference calls in place of in-person meetings, including our annual shareholders meeting which will be held virtually this year. Additionally, travel has been restricted, and we are promoting social distancing, frequent hand washing and thorough disinfection of all surfaces. We have a dedicated executive pandemic response team that meets daily and is closely monitoring developments and providing guidance for additional precautions and initiatives. We are resolute in our commitment to serve our clients and communities just as we have for over 156 years and will do so for many years to come.” Mr. Murphy concluded.

FIRST QUARTER 2020 FINANCIAL RESULTS

Loans

Average loans and leases of $5.10 billion increased $240.21 million, up 4.94% in the first quarter of 2020 from the year ago quarter and have increased $51.76 million, up 1.03% from the fourth quarter of 2019.

Deposits

Average deposits of $5.27 billion grew $213.01 million for the quarter ended March 31, 2020, up 4.21% from the year ago quarter and have decreased $142.05 million, or 2.62% compared to the fourth quarter of 2019.

Net Interest Income and Net Interest Margin

First quarter 2020 net interest income of $54.84 million was relatively flat from the first quarter a year ago and decreased $0.45 million, down 0.82% from the fourth quarter of 2019.

First quarter 2020 net interest margin was 3.57%, a decrease of 21 basis points from the 3.78% for the same period in 2019 and increased six basis points from the fourth quarter of 2019. First quarter 2020 net interest margin on a fully tax-equivalent basis was 3.58%, a decrease of 21 basis points from the 3.79% for the same period in 2019 and was higher by six basis points compared to the previous quarter. The margin continues to experience pressure from the numerous Federal Reserve interest rate decreases during the second half of 2019 and the first three months of 2020. Interest-bearing deposit repricing and a shift in the deposit mix during the first quarter of 2020 resulted in a positive margin impact when compared to the year end margin.

Noninterest Income

First quarter 2020 noninterest income of $24.62 million increased $0.50 million, up 2.06% from the first quarter a year ago and decreased $0.96 million, or 3.73% from the fourth quarter of 2019.

Noninterest income during the three months ended March 31, 2020 was higher compared to a year ago mainly from improved mortgage banking income driven by gains on a higher volume of loan sales, increased gains on the sale of available-for-sale securities, increased gains on partnership investments, higher debit card income and increased service charges on deposit accounts. These positives were offset by lower equipment rental income due to a reduction

in the size of the average equipment rental portfolio, reduced insurance commissions due to a decline in contingent commissions received and decreased customer swap fees.

The decrease in noninterest income from the fourth quarter of 2019 was primarily the result of lower equipment rental income due to a reduction in the size of the average equipment rental portfolio, decreased trust and wealth advisory fees, reduced brokerage fees and commissions, and decreased customer swap fees. These negatives were offset by higher mortgage banking income on a higher volume of loan sales and increased insurance commissions on property and casualty policies.

Noninterest Expense

First quarter 2020 noninterest expense of $46.54 million increased $1.33 million, or 2.94% from the first quarter a year ago and decreased $2.81 million, down 5.70% from the prior quarter. Excluding depreciation on leased equipment, noninterest expenses were up 6.28% from the first quarter a year ago and down 5.15% from the prior quarter.

The increase in noninterest expense during the first quarter compared to a year ago was mainly due to reduced gains on the sale of fixed assets, higher salaries as a result of normal merit increases and slightly increased staffing levels, a rise in the valuation provision for interest rate swaps with customers, and higher business development and marketing expenses due to marketing promotions. These increases were offset by fewer valuation adjustments on repossessed assets, lower leased equipment depreciation resulting from a reduction in the average equipment rental portfolio, a decrease in executive cash incentives, reduced insurance costs due to FDIC assessment credits and higher gains on the sale of off-lease operating equipment.

The decrease in noninterest expense from the prior quarter was primarily the result of decreased group insurance costs on lower claims, fewer valuation adjustments on repossessed assets, a decrease in executive cash incentives, a decline in employee commissions and awards, reduced leased equipment depreciation, and fewer professional consulting fees. These decreases were offset by an increased valuation provision for interest rate swaps with customers and higher collection and repossession expenses.

Credit

The reserve for loan and lease losses as of March 31, 2020 was 2.35% of total loans and leases compared to 2.19% at December 31, 2019 and 2.07% at March 31, 2019. Net charge-offs of $1.81 million were recorded for the first quarter of 2020 compared with net charge-offs of $3.54 million in the same quarter a year ago and $0.64 million of net charge-offs in the prior quarter.

The provision for loan and lease losses was $11.35 million for the first quarter of 2020, an increase of $6.44 million compared with the same period in 2019 and an increase of $8.40 million from the fourth quarter of 2019. The ratio of nonperforming assets to loans and leases was 0.68% as of March 31, 2020, compared to 0.37% on December 31, 2019 and 0.49% on March 31, 2019.

Capital

As of March 31, 2020, the common equity-to-assets ratio was 12.63%, compared to 12.51% at December 31, 2019 and 12.20% a year ago. The tangible common equity-to-tangible assets ratio was 11.53% at March 31, 2020 compared to 11.38% at December 31, 2019 and 11.03% a year earlier. The Common Equity Tier 1 ratio, calculated under banking regulatory guidelines, was 12.57% at March 31, 2020 compared to 12.55% at December 31, 2019 and 12.28% a year ago.

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 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.
