NORTHWEST INDIANA BANCORP

ANNOUNCES EARNINGS FOR THE THREE AND TWELVE MONTHS ENDED

DECEMBER 31, 2018

Munster, Indiana - NorthWest Indiana Bancorp (the “Bancorp” or “NWIN”), the holding company for Peoples Bank (the “Bank”), reported an earnings increase of 40.0% for the three months ended December 31, 2018, compared to the same period in 2017. Net income totaled $2.6 million for the three months ended December 31, 2018, compared to $1.9 million for the three months ended December 31, 2017. The three-month earnings increase is related to a revaluation of the Bancorp’s net deferred tax asset during December 2017, that resulted in a one-time write down of $517 thousand that was recorded as additional income tax expense. The three-month earnings increase is also related to strong loan originations as well as the effects of the merger with First Personal Financial Corp. (“First Personal”), which closed during the third quarter of 2018.

The earnings of $2.6 million for the three months ended December 31, 2018, represent $0.86 earnings per basic and diluted share. For the three months ended December 31, 2018, the return on average assets (ROA) was 0.97% and the return on average equity (ROE) was 10.96%. At December 31, 2018, the Bancorp’s assets totaled $1.1 billion.

For the twelve months ended December 31, 2018, the Bancorp’s net income totaled $9.3 million, compared to $9.0 million for the twelve months ended December 31, 2017, an increase of 4.2%. The twelve-month earnings increase is related to strong loan originations as well as the effects of the merger with First Personal and the tax effects from the Tax Cuts and Jobs Act that, among other changes, reduces the corporate federal income tax rate from 34% to 21% and was effective January 1, 2018. The net income of $9.3 million for the twelve months ended December 31, 2018 represents $3.17 earnings per basic and diluted share. For the twelve months ended December 31, 2018, the ROA was 0.93% and the ROE was 9.88%.

On July 26, 2018, the Bancorp completed its previously announced acquisition of First Personal. During the twelve months ended December 31, 2018, the Bancorp has recorded one-time acquisition expenses of approximately $1.8 million related to the acquisition of First Personal.

In addition, on January 24, 2019, the Bancorp announced that it completed its acquisition of AJS Bancorp, Inc. (“AJSB”). During the twelve months ended December 31, 2018, the Bancorp has recorded one-time acquisition expenses of approximately $245 thousand related to the merger with AJSB.

Excluding the one-time acquisition costs, the Bancorp’s earnings for the twelve months ended December 31, 2018 increased by 24.3% resulting in an ROA of 1.11% and an ROE of 11.79%. See Table 1 below for a reconciliation of these non-GAAP figures to the Bancorp’s GAAP net income.

“With the full integration of our last acquisition, the Bank’s 2018 financial results reflect our ability to execute our strategy. Our earnings continue to be strong enough to provide a great return for shareholders while at the same time investing for the future. By combining operations, we are now a stronger Bank better capable of delivering on our mission to help our customers and communities be more successful,” said Benjamin Bochnowski, president and CEO.

“Our strategy has been simple: expand our market through organic growth and acquisitions, and better serve our customers through the efficient delivery of banking products,” continued Bochnowski. “We have been able to achieve both of those at the same time, which has increased both our scale and array of products the Bank has to offer. Strong increases in revenue from banking services reflect our ongoing focus on the customer and those products that help them better achieve their financial goals.”

“As we look forward to 2019, the Bank is positioned to continue to execute on this strategy. The just-completed acquisition of AJSB gives us a significant presence in the South Suburban Chicagoland market, and efforts to integrate them into Peoples Bank are expected to be completed by midyear. Although there are costs associated with integration, Peoples Bank is positioned to benefit from a larger balance sheet, a larger customer base, and more robust sources of bank services income,” added Bochnowski. “We remain more focused than ever on creating value for all of our stakeholders: our shareholders, our customers, our employees, and the communities we serve.”

“For 2018 the Bancorp’s earnings increased by 4.2%. This increase was supported by its ability to generate $34.4 million in net interest income, which increased by $3.6 million, or 11.7% during the year. Even as the Federal Reserve continued to increase short-term interest rates, the Bancorp’s net interest margin remained stable at 3.81%. During the year, loan balances increased by $144.2 million, or 23.2%. The strong loan growth generated additional interest income to offset increased funding costs. In addition, the Bancorp’s earnings have been enhanced by increased noninterest income, which increased by $1.3 million, or 17.4%,” said Robert Lowry, chief financial officer.

“During 2018, the Bancorp’s asset quality and capital position remained strong. Nonperforming loans to total loans was 0.90% at the end of 2018, while the allowance for loan losses (ALL) and purchased loan reserves represented 1.64% of total loans at year-end. The Bancorp’s tier 1 capital to adjusted average assets stood at 8.6% after the acquisition of First Personal. The Bancorp is well positioned for continued growth,” added Lowry.

Net Interest Income

Net interest income, the difference between interest income from loans and investments and interest expense paid to fund providers, totaled $9.6 million for the three months ended December 31, 2018, compared to $7.8 million for the three months ended December 31, 2017, an increase of $1.8 million or 23.2%. The Bancorp’s net interest margin on a tax-adjusted basis was 3.96% for the three months ended December 31, 2018, compared to 3.86% for the three months ended December 31, 2017. For the twelve months ended December 31, 2018, net interest income totaled $34.4 million, compared to $30.8 million for the twelve months ended December 31, 2017 for an increase of $3.6 million or 11.7%. The Bancorp’s net interest margin on a tax-adjusted basis was 3.81% for the twelve months ended December 31, 2018, compared to 3.84% for the three months ended December 31, 2017. The increased net interest income for both periods is a result of the acquisition through merger of the First Personal loan portfolio and strong loan originations.

Noninterest Income

Noninterest income from banking activities totaled $2.2 million for the three months ended December 31, 2018, compared to $1.9 million for the three months ended December 31, 2017, an increase of $292 thousand or 15.1%. For the twelve months ended December 31, 2018, noninterest income from banking activities totaled $9.1 million, compared to $7.8 million for the twelve months ended December 31, 2017, an increase of $1.3 million or 17.4%. The increase in noninterest income is related to an increase in income from banking services that is a result of the acquisition of First Personal as well as the Bancorp’s continued 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. 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 $8.5 million for the three months ended December 31, 2018, compared to $6.2 million for the three months ended December 31, 2017, an increase of $2.2 million or 35.6%. For the twelve months ended December 31, 2018, noninterest expense totaled $31.4 million, compared to $25.5 million for the twelve months ended December 31, 2017, an increase of $5.9 million or 23.1%. For the twelve months ended December 31, 2018, one-time expenses of $1.8 million have been incurred for the acquisition and merger of First Personal. For the twelve months ended December 31, 2018, one-time expenses of $245 thousand have been incurred for the acquisition and merger of AJSB. In addition to one-time expenses, the acquisition of First Personal and AJSB will also have an impact on the ongoing operating costs of the Bancorp.

For the twelve months ended December 31, 2018, the increase in compensation and benefits is the result of a continued focus on talent management and retention, as well as the acquisition of First Personal. The increase in data processing expense is primarily the result of data conversion expenses related to the acquisition of First Personal and accounts for approximately $982 thousand of the increase shown. The remainder of the increase in data processing is due to increased system utilization. The increase in marketing expense is a result of the acquisition of First Personal. The increase in other operating expenses is primarily related to the acquisition of First Personal and accounts for approximately $609 thousand of one-time expenses and approximately $301 thousand of ongoing expenses that make up the increase for the year ended December 31, 2018. The remainder of the increase in other noninterest expense is primarily related to a shared loss of $125 thousand from the operation of the wholly-owned subsidiary NWIN Risk Management, Inc. (a captive insurance subsidiary), as well as generally higher third party costs.

The Bancorp’s efficiency ratio was 72.2% for the twelve months ended December 31, 2018, compared to 66.2% for the twelve months ended December 31, 2017. Excluding the one-time acquisition expense, the efficiency ratio decreased to 67.4% for the twelve months ended December 31, 2018. 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 $764.4 million at December 31, 2018, compared to $620.2 million at December 31, 2017, an increase of $144.2 million or 23.2%. The increase is the result of the acquisition of First Personal as well as organic loan portfolio growth. During the twelve months ended December 31, 2018, $55.5 million in newly originated fixed rate mortgage loans were sold into the secondary market resulting in gains of $1.6 million. The loan portfolio represents 75.1% of earning assets and is comprised of 61.3% commercial related credits.

Investing

The Bancorp’s securities portfolio totaled $241.8 million at December 31, 2018, compared to $244.5 million at December 31, 2017, a decrease of $2.7 million or 1.1%. The securities portfolio represents 23.7% of earning assets and provides a consistent source of liquidity and earnings to the Bancorp. Cash and cash equivalents totaled $17.1 million at December 31, 2018, compared to $11.0 million at December 31, 2017, an increase of $6.1 million or 55.5%. The increase in cash and cash equivalents will be used to fund first quarter loan originations as well as the acquisition of AJSB.

Funding

At December 31, 2018, core deposits totaled $670.9 million, compared to $609.1 million at December 31, 2017, an increase of $61.8 million or 10.1%. The increase is the result of the acquisition of First Personal as well as the Bancorp’s efforts to maintain core deposits. Core deposits include checking, savings, and money market accounts and represented 72.2% of the Bancorp’s total deposits at December 31, 2018. During the first twelve months of 2018, balances for noninterest and interest bearing checking and savings accounts increased. The increase in these core deposits is a result of deposits that were acquired with the merger of First Personal and management’s sales efforts along with customer preferences for competitively priced short-term liquid investments. For the twelve months ended December 31, 2018, balances for money market accounts decreased as part of cyclical funds flows for municipality customers. At December 31, 2018, balances for certificates of deposit totaled $258.9 million, compared to $183.9 million at December 31, 2017, an increase of $75.0 million or 40.8%. In addition, at December 31, 2018, borrowings and repurchase agreements totaled $54.6 million, compared to $32.2 million at December 31, 2017, an increase of $22.4 million or 69.8%. The increase in short-term borrowings was a result of cyclical municipal deposit balance decreases.

Asset Quality

During 2018, the Bancorp’s management continued focusing on maintaining its historically strong loan underwriting standards. At December 31, 2018, non-performing loans totaled $6.9 million, compared to $5.2 million at December 31, 2017, an increase of $1.7 million or 32.4%. The Bancorp’s ratio of non-performing loans to total loans was 0.90% at December 31, 2018, compared to 0.84% at December 31, 2017. In addition, the Bancorp’s ratio of non-performing assets to total assets was 0.97% at December 31, 2018, compared to 1.00% at December 31, 2017.

For the twelve months ended December 31, 2018, $1.3 million in provisions to the ALL were required, compared to $1.2 million for the twelve months ended December 31, 2017, an increase of $108 thousand or 9.0%. The ALL provision increase is primarily a result of overall loan portfolio growth. For the twelve months ended December 31, 2018, charge-offs, net of recoveries, totaled $1.4 million. At December 31, 2018, the allowance for loan losses totaled $8.0 million and is considered adequate by management. The allowance for loan losses as a percentage of total loans was 1.04% at December 31, 2018, compared to 1.21% at December 31, 2017. The allowance for loan losses as a percentage of non-performing loans, or coverage ratio, was 115.1% at December 31, 2018, compared to 143.3% at December 31, 2017. The decrease in the allowance for loan losses as a percentage of total loans and the coverage ratio are both related to the acquisition of the loan portfolio that was part of the First Personal acquisition and the result of acquisition accounting that requires loans be written down to fair value at acquisition.

Capital Adequacy

At December 31, 2018, shareholders’ equity stood at $101.5 million, and tangible capital represented 9.3% of total assets. The Bancorp’s regulatory capital ratios at December 31, 2018 were 12.6% for total capital to risk-weighted assets, 11.6% for both common equity tier 1 capital to risk-weighted assets and tier 1 capital to risk-weighted assets, and 8.6% for tier 1 leverage capital to adjusted average assets. Under all regulatory capital requirements, the Bancorp is considered well capitalized. The book value of the Bancorp’s stock stood at $33.50 per share at December 31, 2018.
