NORTHWEST INDIANA BANCORP

ANNOUNCES EARNINGS FOR THE SIX AND THREE MONTHS ENDED

JUNE 30, 2018

Munster, Indiana - NorthWest Indiana Bancorp (the “Bancorp” or “NWIN”), the holding company for Peoples Bank (the “Bank”), reported an earnings increase of 5.1% for the six months ended June 30, 2018, compared to the same period in 2017. Net income totaled $5.1 million for the six months ended June 30, 2018, compared to $4.8 million for the six months ended June 30, 2017.

The earnings of $5.1 million for the six months ended June 30, 2018, represent $1.77 earnings per basic and diluted share. For the first six months of 2018, the return on average assets (ROA) was 1.08% and the return on average equity (ROE) was 11.12%. At June 30, 2018, the Bancorp’s assets totaled $959.0 million.

For the three months ended June 30, 2018, the Bancorp’s net income totaled $2.51 million, compared to $2.53 million for the three months ended June 30, 2017, a decrease of 0.7%. The net income of $2.51 million for the three months ended June 30, 2018 represents $0.88 earnings per basic and diluted share. For the three months ended June 30, 2018, the ROA was 1.07% and the ROE was 11.04%.

On February 20, 2018, the Bancorp announced the pending merger with First Personal Financial Corp. (“First Personal”). It is anticipated that the merger will be completed on July 26, 2018. During the first six months of 2018, the Bancorp has recorded one-time acquisition costs of approximately $545 thousand related to the merger with First Personal.

Excluding the one-time acquisition costs, the Bancorp’s earnings for the six months ended June 30, 2018 increased by 14.9% resulting in an ROA of 1.18%. Without the one-time acquisition costs, the Bancorp’s earnings for the three months ended June 30, 2018 increased by 17.7% resulting in an ROA of 1.26%. See Table 1 below for a reconciliation of these non-GAAP figures to the Bancorp’s GAAP net income.

“Financial performance was very strong during the first half of the year, driven primarily by excellent operating results. While we do expect continued acquisition expenses in the second half of the year related to the integration of First Personal, the underlying results provide a substantial foundation for the performance we expect from a fully integrated Bank. Full integration is expected to take place in September 2018, at which point First Personal customers will have full access to our Banking Centers as well as an extended menu of products and services. Additionally, our current customers will have a larger Banking Center network with locations in South Suburban Chicagoland,” said Benjamin Bochnowski, president & chief executive officer.

“During the first six months of 2018, the Bancorp’s earnings increase was driven by 8.4% annualized loan growth, which helped drive the increase in the Bancorp’s net interest income. In addition, for the same period, noninterest income increased 24.2% as a result of management’s focused efforts on executing its operating strategies. Strong asset quality continues to benefit earnings, as nonperforming loans represent only 0.65% of the Bancorp’s loan portfolio. Also, the Bancorp’s low effective tax rate continues to enhance profitability,” said Robert Lowry, chief financial officer.

Net Interest Income

Net interest income, the difference between interest income from loans and investments and interest expense paid to fund providers, totaled $15.7 million for the six months ended June 30, 2018, compared to $15.2 million for the six months ended June 30, 2017, an increase of $538 thousand or 3.5%. The Bancorp’s net interest margin on a tax-adjusted basis was 3.79% for the six months ended June 30, 2018, compared to 3.83% for the six months ended June 30, 2017. For the three months ended June 30, 2018, net interest income totaled $7.9 million, compared to $7.7 million for the three months ended June 30, 2017 for an increase of $218 thousand or 2.8%. The Bancorp’s net interest margin on a tax-adjusted basis was 3.78% for the three months ended June 30, 2018, compared to 3.84% for the three months ended June 30, 2017. The increased net interest income for both periods is a result of an increase in average daily balances for loans.

Noninterest Income

Noninterest income from banking activities totaled $4.7 million for the six months ended June 30, 2018, compared to $3.7 million for the six months ended June 30, 2017, an increase of $907 thousand or 24.2%. For the three months ended June 30, 2018, noninterest income from banking activities totaled $2.2 million, compared to $2.0 million for the three months ended June 30, 2017, an increase of $243 thousand or 12.4%. The increase in noninterest income is related to an increase in income from banking services as the Bancorp continued to focus on being competitive within its market place. Current market conditions also provided opportunities to maintain securities cash flows, while recognizing gains from the sales of securities. Wealth management income increased as assets under management increased and one-time fees were recognized. The increase in gain on sale of loans held for sale is the result of continued efforts on loan growth and normal course of business sales.

Noninterest Expense

Noninterest expense totaled $13.9 million for the six months ended June 30, 2018, compared to $12.3 million for the six months ended June 30, 2017, an increase of $1.5 million or 12.5%. For the three months ended June 30, 2018, noninterest expense totaled $6.9 million, compared to $6.0 million for the three months ended June 30, 2017, an increase of $878 thousand or 14.6%. During 2018, one-time expenses of $545 thousand have been incurred for the planned acquisition of First Personal. In addition, compensation and benefits increased as a result of a continued focus on talent management and retention. Data processing expense included acquisition costs and saw increased system utilization. Other operating expense increased as higher costs were incurred for foreclosure and collection expense, seminars and education, higher third party costs, a shared loss from the operation of the wholly-owned captive insurance subsidiary, and acquisition expenses. The Bancorp’s efficiency ratio was 68.1% for the six months ended June 30, 2018, compared to 65.2% for the six months ended June 30, 2017. Excluding the one-time acquisition expense, the efficiency ratio would decrease to 65.45% for the same period. See Table 1 below for a reconciliation of the non-GAAP figure to the Bancorp’s GAAP efficiency ratio. The efficiency ratio is determined by dividing total noninterest expense by the sum of net interest income and total noninterest income for the period.

Lending

The Bancorp’s loan portfolio totaled $646.3 million at June 30, 2018, compared to $620.2 million at December 31, 2017, an increase of $26.1 million or 4.2%. During the first six months of 2018, the Bancorp originated $177.2 million in new loans, an increase of 6.6% compared to the six months ended June 30, 2017. During the six months ended June 30, 2018, the Bancorp saw its commercial real estate, commercial business, residential real estate, multifamily, construction and land development, and HELOC loan balances increase. During the six months ended June 30, 2018, $22.1 million in newly originated fixed rate mortgage loans were sold into the secondary market resulting in gains of $570 thousand.

Cash and cash equivalents totaled $19.8 million at June 30, 2018, compared to $11.0 million at December 31, 2017, an increase of $8.8 million or 79.5%.

Funding

At June 30, 2018, core deposits totaled $599.2 million, compared to $609.1 million at December 31, 2017, a decrease of $9.9 million or 1.6%.

Core deposits include checking, savings, and money market accounts and represented 74.3% of the Bancorp’s total deposits at June 30, 2018. During the first six months of 2018, balances for interest bearing checking and savings accounts increased. The increase in these core deposits is a result of management’s sales efforts along with customer preferences for competitively priced short-term liquid investments.

In addition, the Bancorp’s ratio of non-performing assets to total assets was 0.78% at June 30, 2018, compared to 1.00% at December 31, 2017.

The ALL provision increase is primarily a result of overall loan portfolio growth. For the six months ended June 30, 2018, charge-offs, net of recoveries, totaled $672 thousand. The net loan charge-offs for the first six months of 2018 were comprised of $106 thousand in residential real estate, $24 thousand in home equity loans, $13 thousand in consumer loans, $412 thousand in commercial business loans, and $117 thousand in commercial real estate.
