NORTHWEST INDIANA BANCORP

ANNOUNCES EARNINGS FOR THE QUARTER AND SIX MONTHS ENDED

June 30, 2019

Munster, Indiana - NorthWest Indiana Bancorp (the “Bancorp” or “NWIN”), the holding company for Peoples Bank SB (the “Bank”), reported record net income of $4.0 million, or $1.17 per share, for the quarter ended June 30, 2019. Net income for the quarter ended June 30, 2019, increased by $1.5 million (60.3%), from the quarter ended June 30, 2018. For the second quarter of 2019, the return on average assets (ROA) was 1.27% and the return on average equity (ROE) was 12.77%.

For the six months ended June 30, 2019, the Bancorp’s net income totaled $6.2 million, or $1.84 per share. Net income for the six months ended June 30, 2019, increased by $1.2 million (23.1%), from the six months ended June 30, 2018. For the first six months of 2019, the ROA was 1.00% and the ROE was 10.25%. In connection with the successful acquisition of AJS Bancorp, Inc., (“AJSB”), which closed on January 24, 2019, the Bancorp incurred one-time expenses of approximately $2.1 million, as expansion into the Chicagoland market continued. In addition to the acquisition of AJSB, on July 26, 2018, the Bancorp completed its acquisition of First Personal Financial Corp., (“First Personal”).

Excluding the one-time AJSB acquisition costs, the Bancorp’s net income, as adjusted, was $8.0 million, or $2.36 per share, for the first six months of 2019. Excluding these same one-time AJSB acquisition costs, the Bancorp’s ROA, as adjusted, was 1.28% and its ROE, as adjusted, was 13.14% for the first six months of 2019. See Table 1 below for a reconciliation of these non-GAAP figures to the Bancorp’s GAAP figures.

During the six months ended June 30, 2019, total assets increased by $213.2 million (19.4%), with interest-earning assets increasing by $180.8 million (17.8%). At June 30, 2019, interest-earning assets totaled $1.2 billion compared to $1.0 billion at December 31, 2018. Earning assets represented 91.6% of total assets at June 30, 2019 and 92.9% of total assets at December 31, 2018. The increase in total assets and interest earning assets for the six months was primarily the result of the completion of the acquisition of AJSB as well as internally generated growth.

“The first six months of 2019 were a record for Peoples Bank, with GAAP net income up 23% compared to 2018. Significantly, second quarter results for GAAP net income were up 60% year over year. The second quarter of 2019 was our best quarter to date, and is the result of both inorganic and organic growth as we continue to execute our strategic plan. Second quarter results are also noteworthy because they were free of any merger-related expenses, which were all accrued during the first quarter of 2019. These results reflect fully integrated operations from all of our acquisitions and organic growth, and demonstrate the value we have been able to create through the execution of our strategic plan,” said Benjamin Bochnowski, president & chief executive officer.

“Results connected to our inorganic growth have exceeded internal expectations. Economic conditions have bolstered our efforts to grow organically, as we see this as the greatest driver to create value for all of our stakeholders. We have been deliberately executing our plans to serve our mission to help our customers and communities be more successful. These results further support our goal of maintaining long-term independence as a community bank,” he continued.

“The Bancorp’s 2019 operating results positively impacted by a 18% growth in interest-earning assets during the first six months of the year. The earning asset growth was attributable to both organic commercial loan originations and mortgage loans attained through our recent acquisitions. Because of the strong earnings asset growth and well-managed cost of funds, the Bancorp’s net interest income for 2019 has increased by $6.1 million, 39%. In addition, the Bancorp’s earnings were benefited by an increase in noninterest income from lending activity and wealth management operations,” said Robert Lowry, chief financial officer.

“After completing the most recent acquisition, the Bancorp’s Tier 1 capital to adjusted average assets stood at 8.5%, which exceeded our pre-acquisition pro formas for the merger with AJSB. With the companies’ now fully integrated, net income accretion to the Bancorp’s capital base will allow for continued execution of our strategic priorities,” added Lowry.

Net Interest Income

Net interest income was $11.2 million for the quarter ended June 30, 2019, an increase of $3.3 million (42.2%), compared to $7.9 million for the quarter ended June 30, 2018. The Bancorp’s net interest margin on a tax-adjusted basis was 3.96% for the quarter ended June 30, 2019, compared to 3.78% for the quarter ended June 30, 2018. Net interest income was $21.8 million for the six months ended June 30, 2019, an increase of $6.1 million (38.7%), compared to $15.7 million for the six months ended June 30, 2018. The Bancorp’s net interest margin on a tax-adjusted basis was 3.88% for the six months ended June 30, 2019, compared to 3.79% for the six months ended June 30, 2018. The increased net interest income for the quarter and the six months was primarily the result of the acquisitions of AJSB and First Personal, internally generated loan growth, and the recognition of one-time gains from excess reserves associated with purchase credit impaired loans from the former acquisitions of First Federal Savings & Loan and Liberty Savings Bank. The recognition of these one-time gains is the result of being able to workout purchase credit impaired loans with better results than were originally anticipated at the time of acquisition.

Noninterest Income

Noninterest income from banking activities totaled $2.7 million for the quarter ended June 30, 2019, compared to $2.2 million for the quarter ended June 30, 2018, an increase of $466 thousand or 21.2%. Noninterest income from banking activities totaled $5.2 million for the six months ended June 30, 2019, compared to $4.7 million for the six months ended June 30, 2018, an increase of $586 thousand or 12.6%. The increase in noninterest income for the quarter and six months is the result of the Bancorp’s continued focus on competitively pricing its fees and service charges as well as its increasing mortgage banking and wealth management activities. The increase in the cash value of bank owned life insurance income was primarily the result of the acquisitions of AJSB and First Personal. The increase in other noninterest income was primarily the result of gains made on the sale of fixed assets.

Noninterest Expense

Noninterest expense totaled $8.4 million for the quarter ended June 30, 2019, compared to $6.9 million for the quarter ended June 30, 2018, an increase of $1.5 million or 22.0%. Noninterest expense totaled $18.7 million for the six months ended June 30, 2019, compared to $13.9 million for the six months ended June 30, 2018, an increase of $4.8 million or 34.9%. For the six months ended June 30, 2019, one-time expenses of $2.1 million have been incurred in connection with the acquisition of AJSB. The increase in compensation and benefits is primarily the result of increased compensation due to the acquisition of AJSB and First Personal. Additionally, increases to compensation and benefits can be attributed to management’s continued focus on talent management and retention. The increase in occupancy and equipment is primarily related to the First Personal and AJSB acquisitions and related assets. The decrease in data processing expense for the quarter ended June 30, 2019, is primarily related to the costs associated with data conversion for the acquisition of First Personal during the second quarter of 2018. The increase in data processing expense for the six months ended June 30, 2019, is primarily the result of data conversion expenses related to the acquisition of AJSB. 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 AJSB as well as the Bancorp’s regular marketing initiatives. The increase in other operating expenses is primarily related to the acquisition of AJSB and accounts for approximately $2.1 million of the increase for the six months ended June 30, 2019.

The Bancorp’s efficiency ratio was 60.73% for the quarter ended June 30, 2019, compared to 68.52% for the quarter ended June 30, 2018. The Bancorp’s efficiency ratio was 69.21% for the six months ended June 30, 2019, compared to 68.13% for the six months ended June 30, 2018. Excluding the one-time acquisition expenses associated with the AJSB transaction, the efficiency ratio would have decreased to 61.40% for the six months ended June 30, 2019. 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 $894.3 million at June 30, 2019, compared to $764.4 million at December 31, 2018, an increase of $129.9 million or 17.0%. The increase is the result of the acquisitions of AJSB and First Personal, as well as organic loan portfolio growth. During the six months ended June 30, 2019, the Bancorp originated $116.1 million in new commercial loans. During the six months ended June 30, 2019, the Bancorp originated $29.6 million in new fixed rate mortgage loans for sale, compared to $24.3 million during the six months ended June 30, 2018. The loan portfolio represents 74.6% of earning assets and is comprised of 57.3% commercial related credits.

Investing

The Bancorp’s securities portfolio totaled $258.7 million at June 30, 2019, compared to $241.8 million at December 31, 2018, an increase of $17.0 million or 7.0%. The securities portfolio represents 21.6% of earning assets and provides a consistent source of liquidity and earnings to the Bancorp. Cash and cash equivalents totaled $61.2 million at June 30, 2019, compared to $17.1 million at December 31, 2018, an increase of $44.0 million or 256.9%. The increase in cash and cash equivalents is the result of the acquisition of AJSB.

Funding

At June 30, 2019, core deposits totaled $809.6 million, compared to $670.9 million at December 31, 2018, an increase of $138.7 million or 20.7%. The increase is the result of the acquisition of AJSB as well as the Bancorp’s efforts to maintain core deposits. Core deposits include checking, savings, and money market accounts and represented 71.8% of the Bancorp’s total deposits at June 30, 2019. During the six months ended June 30, 2019, balances for noninterest bearing checking, interest bearing checking, savings, and money market 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 deposits. At June 30, 2019, balances for certificates of deposit totaled $317.6 million, compared to $258.9 million at December 31, 2018, an increase of $58.7 million or 22.7%. In addition, at June 30, 2019, borrowings and repurchase agreements totaled $38.6 million, compared to $54.6 million at December 31, 2018, a decrease of $16.0 million or 29.3%. The decrease in short-term borrowings was a result of FHLB advance maturities.

Asset Quality

At June 30, 2019, non-performing loans totaled $9.9 million, compared to $6.9 million at December 31, 2018, an increase of $3.0 million or 43.1%. The Bancorp’s ratio of non-performing loans to total loans was 1.11% at June 30, 2019, compared to 0.90% at December 31, 2018. The Bancorp’s ratio of non-performing assets to total assets was 1.03% at June 30, 2019, compared to 0.97% at December 31, 2018.

For the six months ended June 30, 2019, $828 thousand in provisions to the ALL were required, compared to $638 thousand for the six months ended June 30, 2018, an increase of $190 thousand or 29.8%. For the six months ended June 30, 2019, charge-offs, net of recoveries, totaled $46 thousand. At June 30, 2019, the allowance for loan losses totaled $8.7 million and is considered adequate by management. The allowance for loan losses as a percentage of total loans was 0.98% at June 30, 2019, compared to 1.04% at December 31, 2018. The allowance for loan losses as a percentage of non-performing loans, or coverage ratio, was 88.33% at June 30, 2019, compared to 115.1% at December 31, 2018.

Management also considers reserves that are not part of the ALL that have been established from acquisition activity. The Bancorp acquired loans for which there was evidence of credit quality deterioration since origination and it was determined that it was probable that the Bancorp would be unable to collect all contractually required principal and interest payments. At June 30, 2019, total purchased credit impaired loans reserves totaled $2.3 million compared to $3.1 million at December 31, 2018. Additionally, the Bancorp has acquired loans where there was not evidence of credit quality deterioration since origination and has marked these loans to their fair values. As part of the fair value of loans receivable, a net fair value discount was established for loans acquired of $5.0 million at June 30, 2019, compared to $1.8 million at December 31, 2018. When these additional reserves are included on a proforma basis, the allowance for loan losses as a percentage of total loans was 1.78% at June 30, 2019, and the allowance for loan losses as a percentage of non-performing loans, or coverage ratio, was 160.48% at June 30, 2019. See Table 1 below for a reconciliation of these non-GAAP figures to the Bancorp’s GAAP figures.

The Bancorp’s regulatory capital ratios at June 30, 2019, were 12.5% for total capital to risk-weighted assets, 11.5% for both common equity tier 1 capital to risk-weighted assets and tier 1 capital to risk-weighted assets, and 8.5% for tier 1 leverage capital to adjusted average assets.
