ISBA Announces Third Quarter2015 Earnings

Mt. Pleasant, Michigan, October 29, 2015 - Jae A. Evans, Chief Executive Officer of Isabella Bank Corporation (OTCQX:ISBA), announced today that in the third quarter of 2015, the Corporation recorded strong earnings, increased dividends paid, and opened two new offices.

Net income and earnings per common share for the third quarter of 2015 were $4.06 million and $0.52, compared to $3.41 million and $0.44 for the third quarter of 2014. Net income and earnings per common share for the nine months ended September 30, 2015 were $11.83 million and $1.52, compared to $10.28 million and $1.33 for the nine months ended September 30, 2014. During the quarter, the Corporation paid a $0.24 per common share cash dividend. This dividend represented a 9.09%increase over the third quarter of 2014, continuing the Corporation's 33 consecutive years of dividend growth. Based the Corporation's average stock price of $23.46 for the month of September 2015, the annualized cash dividend yield was 3.96%.

During the first nine months of 2015, total assets grew by 4.50% to $1.62 billion and assets under management - which includes loans sold and serviced, and assets managed by the Corporation's Investment and Trust Services Department of $681.39 million - grew to $2.30 billion. Contributing to our growth were increases in our commercial and agricultural loan portfolios of $12.68 million as well as $61.08 million in our available-for-sale securities portfolio. Our focus on balance sheet growth contributes to our commitment to increasing net interest income.

In addition to increased net interest income, improvements in credit quality also contributed to the Corporation's strong earnings. During the first nine months of 2015, the Corporation realized net loan recoveries of $99,000, compared to net loans charged-off of $496,000 for the same period of 2014. Total loans past due and loans classified as less than satisfactory continued to decline during the quarter. These factors allowed for a reduction in the level of the allowance for loan losses in both amount and as a percentage of gross loans, resulting in a reversal of the provision for loan losses of $2.00 million during the nine month period ended September 30, 2015.

During the quarter, Isabella Bank, a wholly owned subsidiary of Isabella Bank Corporation, completed branch acquisitions in Saginaw and Midland. These acquisitions brought in over 1,200 new households and $52.95 million in deposits. With these new locations, the Bank is committed to strengthening its roots within the Midland and Saginaw counties.

Third Quarter 2015 Earnings

October 29, 2015

Dear Shareholder,

In the third quarter of 2015, we recorded strong earnings, increased dividends paid, and opened two new offices. During the three and nine month periods ended September 30, 2015, net income and earnings per common share were $4.06 million and $0.52 and $11.83 million and $1.52, respectively. During the quarter, we paid a $0.24 per common share cash dividend which represented a 9.09%increase over the third quarter of 2014. Based on our average stock price of $23.46 for the month of September 2015, the annualized cash dividend yield was 3.96%.

During the first nine months of 2015, total assets grew by 4.50% to $1.62 billion and assets under management grew to $2.30 billion - which includes loans sold and serviced, and assets managed by our Investment and Trust Services Department of $681.39 million. Contributing to our growth were increases in our commercial and agricultural loan portfolios of $12.68 million as well as $61.08 million in our available-for-sale securities portfolio. Our focus on balance sheet growth contributes to our commitment to increasing net interest income.

In addition to increased net interest income, improvements in credit quality also contributed to our year-to-date earnings. During the first nine months of 2015, we realized net loan recoveries of $99,000, compared to net loans charged-off of $496,000 for the same period of 2014. Total loans past due and loans classified as less than satisfactory also continued to decline during the quarter. These factors allowed us to reduce the level of the allowance for loan losses in both amount and as a percentage of gross loans resulting in a reversal of provision for loan losses of $2.00 million for the nine month period ended September 30, 2015.

During the quarter, we completed branch acquisitions in Saginaw and Midland. We welcomed over 1,200 new households and $52.95 million in deposits to the Isabella Bank family. To celebrate, we hosted an open house earlier in the month at our Saginaw branch and we look forward to an open house in our new Midland branch later this year. We are overwhelmed by the level of support and enthusiasm we have received from each community.

After 30 years with Isabella Bank, Tim Miller retired as Breckenridge Division President. Tim is well respected throughout our organization for his expertise in agricultural and commercial lending. While we will miss his day-to-day contributions, we are privileged to have his continued leadership on our Breckenridge Division Board.

Brian Goward, who has been with us since 1999, has been appointed as our new Breckenridge Division President. Brian has extensive experience in agricultural and commercial lending along with a passion for community involvement. Brian embraces our culture and our community banking heritage, which is essential to our continued success.
