Fourth Quarter and Full Year 2017 Results

HOLLAND, Mich. (January 25, 2018) – Macatawa Bank Corporation (NASDAQ: MCBC) today announced its results for the fourth quarter and full year of 2017, reflecting continued strong financial performance.

·	Net income of $2.2 million in fourth quarter 2017 versus $4.1 million in the fourth quarter 2016

·	Full year 2017 net income of $16.3 million versus $16.0 million in 2016

·	Fourth quarter and full year 2017 earnings were reduced by $2.5 million to record the impact of recently enacted tax reform on the value of the Company’s net deferred tax assets

·	Pretax earnings increased by 13% and 22% for the fourth quarter and full year 2017, respectively, compared to the same periods in the prior year

·	Continued trend of increased total revenue with reduction in expenses

·	Loan portfolio balances up by $40 million (3%), from a year ago

·	Bond financing to business customers up by $26 million from a year ago

·	Core deposit balances up by $130 million (9%), from a year ago

·	Asset quality metrics remained strong

Macatawa reported net income of $2.2 million, or $0.06 per diluted share, in the fourth quarter 2017 compared to $4.1 million, or $0.12 per diluted share, in the fourth quarter 2016. For the full year 2017, the Company reported net income of $16.3 million, or $0.48 per diluted share compared to $16.0 million, or $0.47 per diluted share, for the same period in 2016. The fourth quarter and full year 2017 earnings were reduced by $2.5 million resulting from an increase in federal income tax expense necessary to revalue the Company’s net deferred tax assets at the end of the year.

On December 22, 2017, “H.R.1”, formerly known as the “Tax Cuts and Jobs Act”, was signed into law. This new tax law, among other items, reduces the Company’s federal corporate tax rate from 35% to 21% effective January 1, 2018. Macatawa anticipates that this tax rate change should reduce its federal income tax liability in future years beginning with 2018. However, the new tax law impacted the Company’s 2017 operating results as well. U.S. generally accepted accounting principles require companies to re-value their deferred tax assets and liabilities as of the date of enactment, with resulting tax effects accounted for in the reporting period of enactment. Since the enactment took place in December 2017, the Company revalued downward its net deferred tax assets in its reporting periods ended December 31, 2017 resulting in the $2.5 million reduction to earnings in those periods.

“We are pleased to report strong operating performance for the fourth quarter and full year of 2017”, said Ronald L. Haan, President and CEO of the Company. “Earnings improvement continues to be driven primarily by improvement in net interest income resulting from growth in balances of loans and bond financing to businesses, supported by strong growth in core deposit funding. Portfolio loans and business bond financing, on a combined basis, grew by 5% while core deposits grew by 9% in 2017. At the same time, asset quality remains strong with low levels of past due loans and non- performing assets, and now achieving five consecutive full years of net recoveries on previously charged-off loans.”

Mr. Haan concluded, “Our long term strategy of driving profitable growth continues to deliver results as we remain committed to operating a well-disciplined company that will deliver superior financial services to the communities of Western Michigan, while also providing strong and consistent financial performance for our shareholders.”

Net interest income for the fourth quarter 2017 totaled $13.5 million, an increase of $379,000 from the third quarter 2017 and an increase of $1.2 million from the fourth quarter 2016. Net interest margin was 3.25 percent, up 4 basis points from the third quarter 2017, and up 8 basis points from the fourth quarter 2016.

Average interest earning assets for the fourth quarter 2017 increased $29.3 million from the third quarter 2017 and were up $115.1 million from the fourth quarter 2016 primarily due to growth on the funding side of the balance sheet in core deposits.

Non-interest income increased $110,000 in the fourth quarter 2017 compared to the third quarter 2017 and decreased $446,000 from the fourth quarter 2016. These fluctuations were primarily driven by gains on sales of mortgage loans. Gains on sales of mortgage loans in the fourth quarter 2017 were down $68,000 compared to the third quarter 2017 and down $488,000 from the fourth quarter 2016. The Bank originated $12.0 million in loans for sale in the fourth quarter 2017 compared to $11.3 million in loans for sale in the third quarter 2017 and $27.3 million in loans for sale in the fourth quarter 2016. Non-interest income in the third quarter 2017 was also impacted by $172,000 in net loss on sale of a property the Bank had held as a potential branch location.

Non-interest expense was $11.3 million for the fourth quarter 2017, compared to $10.8 million for the third quarter 2017 and $11.5 million for the fourth quarter 2016. The largest component of non-interest expense was salaries and benefit expenses. Salaries and benefit expenses were up $229,000 compared to the third quarter 2017 and were up $95,000 compared to the fourth quarter 2016. For the full year 2017, salaries and benefits were down $64,000 compared to 2016. Total salaries and benefits expense has remained at a consistent level over the past several quarters and full years due to efforts to prudently manage overall cost levels. The largest fluctuation between periods in non-interest expense was in nonperforming asset expenses. Nonperforming asset expenses increased $282,000 compared to the third quarter 2017 and increased $105,000 compared to the fourth quarter 2016. For the full year, nonperforming asset expenses were just $65,000 in 2017, compared to $1.3 million in 2016. Total net realized losses on sales of other real estate owned properties were $103,000 for the fourth quarter 2017 compared to net realized gains of $190,000 for the third quarter 2017 and net gains of $280,000 for the fourth quarter 2016. Other categories of non-interest expense in the fourth quarter 2017 were relatively flat compared to the third quarter 2017 and the fourth quarter 2016.

All in, total revenue, including both net interest income and non-interest income, grew by $2.7 million while non-interest expenses decreased by $2.1 million in 2017.

Federal income tax expense was $4.5 million for the fourth quarter 2017 compared to $2.2 million for the third quarter 2017 and $1.8 million for the fourth quarter 2016. Federal income tax expense for the fourth quarter 2017 included a $2.5 million expense to revalue the Company’s net deferred tax assets in response to the tax reform law enacted in December 2017.

Macatawa Bank Corporation 4Q Results / page 3 of 5

As a result of the consistent improvements in nonperforming loans and past due loans over the past several quarters, the reduction in historical loan loss ratios, and net loan recoveries experienced in the fourth quarter 2017, no provision for loan losses was recorded in the fourth quarter 2017. Net loan recoveries for the fourth quarter 2017 were $166,000, compared to third quarter 2017 net loan recoveries of $214,000 and fourth quarter 2016 net loan recoveries of $364,000. The Company has experienced net loan recoveries in each of the past twelve quarters and in the past five consecutive full years. Total loans past due on payments by 30 days or more were negligible and amounted to $995,000 at December 31, 2017, down 31 percent from $1.4 million at December 31, 2016. Delinquency as a percentage of total loans was 0.08 percent at December 31, 2017, down from 0.11 percent at December 31, 2016.

The allowance for loan losses of $16.6 million was 1.26 percent of total loans at December 31, 2017, compared to 1.30 percent of total loans at September 30, 2017, and 1.32 percent at December 31, 2016. The coverage ratio of allowance for loan losses to nonperforming loans continued to be strong and significantly exceeded 1-to-1 coverage at 42.0-to-1 as of December 31, 2017.

At December 31, 2017, the Company's nonperforming loans were $395,000, representing 0.03 percent of total loans. This compares to $521,000 (0.04 percent of total loans) at September 30, 2017 and $300,000 (0.02 percent of total loans) at December 31, 2016. Other real estate owned and repossessed assets were $5.8 million at December 31, 2017, compared to $6.7 million at September 30, 2017 and $12.3 million at December 31, 2016. Total nonperforming assets, including other real estate owned and nonperforming loans, have decreased by $6.5 million, or 53 percent, from December 31, 2016 to December 31, 2017.

Commercial loans increased by $39.8 million from December 31, 2016 to December 31, 2017, partially offset by a decrease of $323,000 in the Company’s residential mortgage and consumer loan portfolios. Commercial real estate loans increased by $23.9 million while commercial and industrial loans increased by $15.9 million during the same period.

The composition of the commercial loan portfolio is shown in the table below:

The increase in total deposits from December 31, 2016 was across most deposit types. The increase in interest-bearing checking of $68.2 million was partially offset by a decrease of $10.9 million in non-interest checking. The other categories of deposits all increased including money market deposits (up $47.1 million), savings (up $8.1 million) and certificates of deposit (up $17.8 million). The Bank continues to be successful at attracting and retaining core deposit customers. Customer deposit accounts remain insured to the highest levels available under FDIC deposit insurance.

The Bank's risk-based regulatory capital ratios at December 31, 2017 decreased slightly compared to September 30, 2017 and December 31, 2016 due to asset growth, partially offset by earnings growth. All categories continue to be at levels comfortably above those required to be categorized as “well capitalized” under applicable regulatory capital guidelines. As such, the Bank was categorized as "well capitalized" at December 31, 2017.
