ANNOUNCES RECORD EARNINGS FOR 2015

Munster, Indiana - NorthWest Indiana Bancorp (the “Bancorp”), the holding company for Peoples Bank (the “Bank”), reported an annual earnings increase of 6.2%, as net income totaled $7.9 million for 2015, compared to $7.4 million for 2014. The 2015 net income figure of $7.9 million represents the fourth consecutive year of record earnings for the Bancorp, exceeding its prior earnings record for 2014. At December 31, 2015, the Bancorp’s assets totaled $864.9 million compared to $775.0 million at December 31, 2014, an increase of $89.8 million or 11.6%.

The 2015 net income of $7.9 million represents $2.75 earnings per basic and diluted share. For 2015, the return on average assets (ROA) was 0.96% and the return on average equity (ROE) was 9.90%.

“Peoples Bank reported another strong year as our income for 2015 rose to an all-time high of $7.9 million. Not only did we exceed the prior record set in 2014, but we successfully completed the merger with Liberty Savings. Peoples Bank now has 16 locations to better serve our retail and small business customers throughout Lake and Porter counties,” said David A. Bochnowski, chairman and chief executive officer.

“Our loan growth during 2015 demonstrates that small business and retail customers look to Peoples to fulfill their lending needs. During the year, the Bank originated $321.3 million in new loans, an increase of 44.3% over 2014. The local economy is on the upswing, and the Peoples team continues to work very hard to respond on a timely basis to lending opportunities,” Bochnowski said.

“As a community bank with local decision makers, Peoples is well positioned to compete with large regional and national banking competitors. Our loan officers know our community, and we bring to the table up-to-date personal and electronic banking services to match our one hundred and five years of experience serving the banking needs of our customers,” Bochnowski noted.

Bochnowski attributed the Bank’s record earnings to the successful acquisition of Liberty Savings, loan growth, core deposit growth, core earnings, income from banking operations including mortgage loan sales and wealth management operations, and continued strong asset quality. The Bank’s total assets under management including wealth management operations were $1.15 billion at year end.

“This year shows the results of everyone’s hard work here at Peoples Bank. With another year of solid performance, we have created a platform that will allow us to continue to grow and remain independent. For 2016, we are focused on Business Banking, Wealth Management, Mortgage Lending, and Core Funding. Cybersecurity remains a priority to the industry and to our company, and we will continue to enhance our technology and human intelligence in order to keep the Bank safe,” said Benjamin Bochnowski, president and chief operating officer. “We have all the tools and talent necessary to create value for all of our stakeholders: our shareholders, our employees, our customers and our communities,” Bochnowski said.

For the three months ended December 31, 2015, the Bancorp’s net income totaled $2.0 million, compared to $1.7 million for the three months ended December 31, 2014, an increase of $302 thousand, or 17.5%. The net income of $2.0 million for the three months ended December 31, 2015 represents $0.72 earnings per basic and diluted share. For the three months ended December 31, 2015, the ROA was 0.95% and the ROE was 9.95%.

Net Interest Income

Net interest income, the difference between interest income from loans and investments and interest expense paid to funds providers, totaled $27.4 million for 2015, compared to $25.4 million in 2014 for an increase of $2.0 million or 7.9%. The Bancorp’s net interest margin on a tax adjusted basis was 3.82% for 2015, compared to 3.81% for 2014. For the three months ended December 31, 2015, net interest income totaled $7.3 million, compared to $6.5 million for the three months ended December 31, 2014 for an increase of $805 thousand or 12.5%.

During 2015, the Bancorp’s net interest income was positively impacted by strong balance sheet growth, as interest earning assets increased by $83.6 million or 11.5% since December 31, 2014.

Noninterest Income

Noninterest income from banking activities totaled $6.9 million for 2015, compared to $6.1 million in 2014 for an increase of $776 thousand or 12.8%. The noninterest income increase for 2015 is primarily due to higher income from gains on loan sales related to increased origination volume, wealth management operations, income from banking services, gains on sale of securities, and an increase in the cash value of bank-owned life insurance. For the three months ended December 31, 2015, noninterest income totaled $1.6 million, compared to $1.5 million for the three months ended December 31, 2014, for an increase of $37 thousand or 2.4%. The noninterest income increase for the three month period is primarily a result of higher income from loan sales and income from banking services.

Noninterest Expense

Noninterest expense related to operating activities totaled $23.6 million for 2015, compared to $21.0 million in 2014 for an increase of $2.6 million or 12.4%. For the three months ended December 31, 2015, noninterest expense totaled $6.1 million, compared to $5.5 million for the three months ended December 31, 2014, for an increase of $578 thousand or 10.5%. The increase in noninterest expense for both periods is primarily related to the Bancorp’s acquisition of Liberty Savings Bank during 2015 and First Federal of Hammond during 2014. During 2015, one-time expenses of $452 thousand were incurred for the acquisition of Liberty Savings Bank. In addition, 2015 compensation, occupancy costs, FDIC insurance premiums and other operating expenses are elevated as a result of integrating First Federal of Hammond and incurring operating expenses for a full year, and Liberty Savings Bank’s operating expenses for the second half of 2015. In addition, to enhance organic growth, operating costs are being incurred to grow the Bancorp’s lending team.

The Bancorp’s loan portfolio totaled $571.9 million at December 31, 2015, an increase of $83.7 million or 17.2%, compared to December 31, 2014.

Cash & cash equivalents totaled $11.5 million at December 31, 2015, compared to $22.0 million at December 31, 2014, a decrease of $10.4 million or 47.5%.
