1st Source Corporation (NASDAQ: SRCE), parent company of 1st Source Bank, today reported a record high net income of $16.21 million for the first quarter of 2017, an increase of 17.28% compared to $13.82 million reported in the first quarter a year ago. The net income comparison was positively impacted by gains of $1.29 million on the sale of investment securities available-for-sale, mortgage backed security prepayments of $0.45 million and gains on the sale of fixed assets of $0.20 million. These positives were partially offset by the writedown of fixed assets of $0.41 million and a contribution expense of $0.50 million to the 1st Source Foundation.

Diluted net income per common share for the first quarter of 2017 was also a record high at $0.62, versus $0.53 in the first quarter of 2016.

At its April 2017 meeting, the Board of Directors approved an increase in cash dividend to $0.19 per common share. This is an increase of 5.56% over the $0.18 per common share in the prior quarter. The cash dividend is payable to shareholders of record on May 2, 2017 and will be paid on May 12, 2017.

According to Christopher J. Murphy III, Chairman, “1st Source Corporation had a solid first quarter. Credit quality remained stable while we managed an increase in our net interest margin. We have maintained noninterest expenses at a level similar to the same quarter a year ago while seeing an increase in both net interest income and noninterest income.”

“During the quarter, we razed our outdated facility on North Calumet Avenue in Valparaiso, Indiana, and broke ground on a new banking center at the same location. We look forward to completing construction and continuing to grow in this market for many years. We also announced the closing of three other facilities in markets well served by other nearby 1st Source banking centers. In addition, we announced the opening of our new Sarasota banking center to serve our clients who move to Florida and wish to continue their strong personal and business relationships with the Bank. This is especially true with our wealth advisory and private banking clients.”

“It is important to note that our first quarter was positively impacted from the sale of securities the Bank has held for quite some time and from favorable credit trends, including recoveries, when compared to the first quarter of 2016.”

“As always, we will continue to help our clients achieve security, build wealth and realize their dreams,” Mr. Murphy concluded.

FIRST QUARTER 2017 FINANCIAL RESULTS

Loans

Average loans and leases of $4.19 billion increased $178.80 million, or 4.46% in the first quarter of 2017 from the year ago quarter and have increased $37.32 million from the fourth quarter.

Deposits

Average deposits of $4.30 billion grew $145.69 million, or 3.51% for the quarter ended March 31, 2017 from the year ago quarter and have decreased $103.26 million, or 2.35% compared to the fourth quarter.

Net Interest Income and Net Interest Margin

First quarter 2017 net interest income of $43.73 million increased $2.44 million, or 5.90% from the first quarter a year ago and increased slightly from the fourth quarter.

First quarter 2017 net interest margin was 3.49%, an improvement of 8 basis points from the 3.41% for the same period in 2016 and increased 10 basis points from the 3.39% in the fourth quarter. First quarter 2017 net interest margin on a fully tax-equivalent basis was 3.53%, an increase of 8 basis points from the 3.45% for the same period in 2016 and improved 11 basis points from the 3.42% in the fourth quarter.

Noninterest Income

Noninterest income for the first quarter of 2017 was $23.31 million, up $1.68 million, or 7.77% from the year ago quarter, and up $0.95 million, or 4.25% from the fourth quarter. The growth in noninterest income during the first quarter from the same quarter a year ago was mainly due to gains on the sale of available-for-sale equity securities, higher equipment rental income related to an increase in the average equipment rental portfolio and increased trust and wealth advisory fees, which was offset by reduced partnership gains, resulting from the partial liquidation of an investment during the first quarter of 2016, lower monogram fund income and decreased customer swap fees. The rise in noninterest income from the fourth quarter was primarily as a result of the receipt of insurance contingent commissions, gains on the sale of available-for-sale equity securities, and higher equipment rental income related to an increase in the average equipment rental portfolio.

Noninterest Expense

Noninterest expense for the quarter ended March 31, 2017 was $41.12 million, up $0.41 million, or 1.02% over the comparable period a year ago and down $0.64 million, or 1.54% from the fourth quarter. Excluding depreciation on leased equipment, noninterest expenses were down slightly for the quarter ended March 31, 2017. The increase in noninterest expense from the same quarter a year ago was primarily due to charitable contributions, higher depreciation on leased equipment, and increased loan and lease collection and repossession expenses and the writedown of fixed assets, offset by reduced residential mortgage foreclosure expenses, lower FDIC insurance assessments, decreased professional fees and gains on the sale of fixed assets. The reduction in noninterest expense from the fourth quarter of 2016 was due to a decrease in group insurance claims, reduced professional consulting fees, gains on the sale of fixed assets and lower furniture and equipment expense, offset by the writedown of fixed assets and a loss on the sale of a repossessed asset.

Credit

The reserve for loan and lease losses as of March 31, 2017 was 2.13% of total loans and leases compared to 2.11% at December 31, 2016 and 2.21% at March 31, 2016. Net recoveries of $0.58 million were recorded for the first quarter of 2017 compared with net recoveries of $0.21 million in the same quarter a year ago and down from the $1.10 million of net charge-offs in the fourth quarter.

The ratio of nonperforming assets to loans and leases was 0.63% as of March 31, 2017, comparable to the 0.51% on March 31, 2016 and the 0.70% on December 31, 2016.

Capital

As of March 31, 2017, the common equity-to-assets ratio was 12.47%, compared to 12.26% at December 31, 2016 and 12.39% a year ago. The tangible common equity-to-tangible assets ratio was 11.11% at March 31, 2017 and 10.89% at December 31, 2016 compared to 10.96% a year earlier. The Common Equity Tier 1 ratio, calculated under banking regulatory guidelines, was 12.69% at March 31, 2017 compared to 12.59% at December 31, 2016 and 12.37% a year ago.

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.

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.
