FOR IMMEDIATE RELEASE

OTTAWA BANCORP, INC.

Announces 2016 Results

Ottawa, Illinois – February 6, 2017 - Ottawa Bancorp, Inc. (the “Company”) (Nasdaq CM: OTTW), the holding company for Ottawa Savings Bank FSB (the “Bank”), announced net income of $1.3 million, or $0.43 per basic common share and $0.42 per diluted common share for the year ended December 31, 2016, compared to net income of $771,000, or $0.27 per basic and diluted common share, for the year ended December 31, 2015.

Comparison of Results of Operations for the Years Ended December 31, 2016 and December 31, 2015

Net income for the year ended December 31, 2016 increased $490,000, or 63.6%, to $1.3 million compared to net income of $771,000 for the year ended December 31, 2015. The increase was primarily attributed to the increase in net interest income after provision for loan losses of $223,000, a $240,000 increase in total other income and a reduction of $382,000 in other expenses. These favorable variances were partially offset by an increase of $354,000 in income tax expense.

Net interest income increased by $395,000 or 5.5% to $7.6 million for the year ended December 31, 2016, from $7.2 million for the year ended December 31, 2015. Interest and dividend income increased $344,000 or 4.3%, primarily due to an increase in the average balances of interest-earning assets of $9.4 million, offset by a decrease in the yield on interest-earning assets from 4.08% to 4.06% due to changes in the mix of the portfolio. The increase in net interest income also included a $51,000, or 5.6%, decrease in interest expense. The average cost of funds declined four basis points, from 0.53% to 0.49%, or 7.6%, for the year ended December 31, 2016 compared to the year ended December 31, 2015, due to changes in the mix of lower costing deposit products and certificates of deposit. Additionally, the average balance of interest-bearing liabilities increased by $1.8 million, or 1.0%. The net interest margin increased during the year ended December 31, 2016 to 3.65% compared to 3.62% for the year ended December 31, 2015, primarily as a result of the decrease in the average cost of interest-bearing liabilities outpacing the decline in yield on interest-earning assets as higher costing certificates of deposits and Federal Home Loan Bank advances become a smaller portion of the liability funding base.

We recorded a provision for loan losses of $443,000 for the year ended December 31, 2016 compared to a $270,000 provision for the year ended December 31, 2015. The increase in the provision for loans losses was primarily a function of an increase in the balances of all loan categories, with purchased auto loans doubling since 2015 and higher specific reserves required on several properties that management determined will more than likely be foreclosed upon over next 24 months. Net charge-offs in 2016 were $419,000 compared to $361,000 in 2015. The allowance for loan losses was $2.2 million or 1.35% of total loans at December 31, 2016 compared to $2.2 million, or 1.56%, at December 31, 2015.

Non-interest income increased $240,000, or 15.9%, to $1.7 million for the year ended December 31, 2016, from $1.5 million for the year ended December 31, 2015. The increase was primarily due to a $282,000 increase in gain on sale of loans, an increase of $52,000 in origination of mortgage servicing rights, net of amortization, and an increase of $41,000 in loan origination and servicing income. These increases were partially offset by a decrease of $40,000 in gains on sale of other real estate owned, and a decrease of $29,000 in gains on sale of securities.

Non-interest expense decreased $382,000, or 5.2%, to $7.0 million for the year ended December 31, 2016 from $7.4 million for the year ended December 31, 2015.  The decrease was primarily due to a $893,000 decrease in data processing expense. Additionally, deposit insurance premiums decreased by $66,000, valuation adjustments and expenses on foreclosed real estate declined by $67,000 and legal and professional services declined by $45,000. Offsetting these decreases, salaries and employee benefits increased by $599,000 due to the addition of mortgage loan originators and support staff to support the growth in mortgage processing. Additionally, loan expense increased by $98,000 due to the increase in loan originations, and other expenses increased by $72,000.

We recorded income tax expense of $600,000 and $246,000 for the years ended December 31, 2016 and 2015, respectively.

Comparison of Financial Condition at December 31, 2016 and December 31, 2015:

Total consolidated assets as of December 31, 2016 were $230.2 million, an increase of $16.6 million, or 7.8%, from $213.6 million at December 31, 2015.  The increase was primarily due to increases in the loan portfolio of $20.5 million. This increase was partially offset by a decrease in securities available-for-sale of $2.4 million, $1.2 million in cash and cash equivalents, $0.6 million in non-marketable equity securities and $0.3 million in other real estate owned.

Cash and cash equivalents decreased $1.2 million, or 16.7%, to $5.9 million at December 31, 2016 from $7.1 million at December 31, 2015. The decrease in cash and cash equivalents was primarily a result of cash used in investing activities of $19.0 million exceeding cash provided by financing activities of $15.3 million and cash provided by operating activities of $2.5 million. The cash used in investing activities included a net increase in loans of $21.2 million and the purchase of $7.2 million in securities, offset by the security sales, maturities and pay-downs of $8.4 million. The cash provided by financing activities included proceeds from the stock offering, net of expenses, of $22.3 million, and FHLB advances of $10.0 million, offset by FHLB advance repayments of $11.0 million, a net increase in deposits of $4.1 million and the purchase of $1.9 million in ESOP shares.

Securities available-for-sale decreased $2.4 million, or 5.2%, to $44.6 million at December 31, 2016 from $47.0 million at December 31, 2015.  The decrease was primarily due to sales and maturities of $2.0 million and pay-downs of $6.4 million, exceeding new securities purchases of $7.2 million and the unrealized gain on securities available for sale decreasing by $606,000 due to the increase in market interest rates.

Net loans increased by $20.5 million to $160.6 million at December 31, 2016 compared to $140.1 million at December 31, 2015 as a result of a $4.6 million increase in one-to-four family loans, a $1.2 million increase in multifamily loans, a $4.6 million increase in commercial loans, a $2.4 million increase in commercial real estate and nonresidential loans, a $6.5 million increase in the purchased auto portfolio and a $1.2 million increase in consumer loans.

Foreclosed real estate owned decreased $280,000 to $33,000 at December 31, 2016 from $313,000 at December 31, 2015. The decrease was primarily due to the sale of 11 properties with proceeds of approximately $490,000 during 2016, offset by an increase as a result of three properties valued at approximately $235,000 acquired through or in lieu of foreclosure.

Total deposits decreased $4.2 million, or 2.4%, to $172.5 million at December 31, 2016 from $176.7 million at December 31, 2015. Certificates of deposit decreased $6.5 million, or 7.4%, to $81.2 million at December 31, 2016 from $87.7 million at December 31, 2015. Savings increased by $1.3 million and checking/money market accounts increased by $1.0 million during the same period. The decrease in certificates of deposit and the increase in savings and checking/money market accounts is due to management’s continued efforts to strategically price interest rates to position the Bank for rising interest rates and customers seeking non-term products as they wait for a better rate environment.

FHLB of Chicago advances decreased $1.0 million, or 58.3%, to $1.1 million at December 31, 2016 from $2.1 million at December 31, 2015. The Company made principal payments of $11.0 million and took new advances of $10.0 million during 2016.

Total stockholders’ equity increased $21.3 million or 69.3% to $52.0 million at December 31, 2016 from $30.7 million at December 31, 2015. The increase resulted primarily from the proceeds of the second-step offering to raise capital during the fourth quarter of 2016, in addition to net income of $1.3 million.
