DETROIT, MI, October 23, 2018 -- Chemical Financial Corporation ("Chemical," "we," "us" or "our") (NASDAQ:CHFC) today announced 2018 third quarter net income of $70.4 million, or $0.98 per diluted share, compared to 2018 second quarter net income of $69.0 million, or $0.96 per diluted share and 2017 third quarter net income of $40.5 million, or $0.56 per diluted share. Net income in the third quarter of 2017 excluding merger and restructuring expenses ("significant items"), a non-GAAP financial measure, was $54.2 million, or $0.76 per diluted share.⁽¹⁾ In addition, on October 23, 2018, our Board of Directors declared a fourth quarter of 2018 dividend on our common stock of $0.34 per share. The fourth quarter of 2018 dividend will be payable on December 21, 2018, to shareholders of record on December 7, 2018.

Our net interest income was $159.5 million in the third quarter of 2018, $1.9 million, or 1.2%, higher than the second quarter of 2018 and $15.9 million, or 11.0%, higher than the third quarter of 2017. The increase in our net interest income in the third quarter of 2018, compared to both the second quarter of 2018 and the third quarter of 2017, was primarily attributable to increases in average balances and yields earned on loans and investment securities, partially offset by increases in average deposit balances and cost of funds. Third quarter 2018 net loan growth was $216.6 million, or an annualized growth rate of 5.9%, and net loan growth over the past twelve months was $962.9 million, or 7.0%. Approximately 70% of our loan growth in the third quarter of 2018 was within our commercial loan portfolio. Our investment securities portfolio grew by $212.7 million, compared to the second quarter of 2018, and $658.4 million, compared to the third quarter of 2017.

Our net interest margin was 3.42% in the third quarter of 2018, compared to 3.54% in the second quarter of 2018 and 3.40% in the third quarter of 2017. Our net interest margin (fully taxable equivalent (FTE)), a non-GAAP financial measure, was 3.48% in the third quarter of 2018, compared to 3.59% in the second quarter of 2018 and 3.48% in the third quarter of 2017.⁽¹⁾ The decrease in our net interest margin (FTE), in the third quarter of 2018, compared to the second quarter of 2018, was primarily due to an increase in average deposit balances and cost of funds. Our net interest margin (FTE) in the third quarter of 2018, and the third quarter of 2017 remained the same, as the increase in average deposit balances and costs of funds in the third quarter of 2018 was offset by increases in yields and average balances on loans and investment securities . Our average cost of funds was 0.88% in the third quarter of 2018, compared to 0.76% in the second quarter of 2018 and 0.53% in the third quarter of 2017. The average yield on our loan portfolio increased to 4.68% in the third quarter of 2018, compared to 4.63% in the second quarter of 2018 and 4.31% in the third quarter of 2017. Interest accretion from purchase accounting discounts on acquired loans contributed 23 basis

Our total provision for loan losses was $6.0 million in the third quarter of 2018, compared to $9.6 million in the second quarter of 2018 and $5.5 million in the third quarter of 2017. The decrease in our total provision for loan losses in the third quarter of 2018, compared to the second quarter of 2018, was primarily the result of a lower amount of originated loan growth and improvements in the collateral position of loans that are individually evaluated for impairment and overall credit quality, partially offset by $970 thousand of impairment recorded during the third quarter of 2018 as a result of the quarterly re-estimation of cash flows on our acquired loan portfolio. The increase in the provision for loan losses in the third quarter of 2018, compared to the third quarter of 2017, was primarily the result of an increase in impairment recorded as a result of the quarterly re-estimation of cash flows on our acquired loan portfolio. All acquired loans were recorded at their estimated fair value at each respective acquisition date without a carryover of the related allowance and, as of September 30, 2018 and September 30, 2017, the allowance recorded for this population of loans was $970 thousand and $579 thousand, respectively. At June 30, 2018, we determined no allowance was needed for our acquired loan portfolio.

Our nonperforming loans totaled $96.7 million at September 30, 2018, compared to $66.7 million at June 30, 2018 and $54.3 million at September 30, 2017. Nonperforming loans comprised 0.65% of total loans at September 30, 2018, compared to 0.46% at June 30, 2018 and 0.39% at September 30, 2017. The increase in nonperforming loans in the third quarter of 2018, compared to the second quarter of 2018, was primarily due to one real estate construction loan relationship and one commercial loan relationship that we downgraded to nonaccrual status during the third quarter of 2018. For each of these nonaccrual loans, we have either established a specific reserve within our allowance for loan losses or charged the loan relationship down to the value of the underlying collateral.

Our total allowance for loan losses was $104.0 million at September 30, 2018, including $103.1 million for our originated loan portfolio and $970 thousand for our acquired loan portfolio. Our allowance for loan losses on our originated loan portfolio was $103.1 million, or 0.93% of originated loans, at September 30, 2018, compared to $100.0 million, or 0.94% of originated loans, at June 30, 2018 and $85.2 million, or 0.93% of originated loans, at September 30, 2017. Our allowance for loan losses on our originated loan portfolio as a percentage of nonperforming loans decreased to 106.6% at September 30, 2018, compared to 149.9% at June 30, 2018 and 156.9% at September 30, 2017, primarily due to improvements in the collateral position of loans that are individually evaluated for impairment and overall credit quality. The results of our quarterly re-estimation of cash flows on our acquired loan portfolio resulted in $970 thousand of allowance established for our acquired loan portfolios as of September 30, 2018, compared to no allowance as of June 30, 2018 and a $579 thousand allowance as of September 30, 2017.

Our noninterest income was $37.9 million in the third quarter of 2018, compared to $38.0 million in the second quarter of 2018 and $32.1 million in the third quarter of 2017. Noninterest income in the third quarter of 2018 decreased, compared to the second quarter of 2018, primarily due to a decrease in wealth management revenue of $1.1 million, partially offset by the change in the impact to earnings from the change in fair valuation in loan servicing rights, included within net gain on sale of loans and other mortgage banking revenue, of $1.0 million. Noninterest income in the third quarter of 2018 increased compared to the third quarter of 2017, primarily due to the change in the impact to earnings from the change in fair valuation in loan servicing rights of $5.0 million. Net gain on sale of loans and other mortgage banking revenue, included a $0.9 million benefit to earnings due to a change in fair value in loan servicing rights in the third quarter of 2018, compared to a $30 thousand detriment in the second quarter of 2018 and a $4.0 million detriment in the third quarter of 2017. The change in fair value in loan servicing rights provided $0.01 to diluted earnings per share in the third quarter of 2018, compared to no impact in the second quarter of 2018 and a $0.04 detriment in the third quarter of 2017.

Our operating expenses were $109.7 million in the third quarter of 2018, compared to $104.6 million in the second quarter of 2018 and $119.5 million in the third quarter of 2017. We had no merger and restructuring expenses during the third or second quarters of 2018, compared to $21.2 million in the third quarter of 2017. Third quarter of 2018 included $3.2 million of impairment related to a federal historic tax credit placed into service during the quarter, included within other operating expense in our Consolidated Statements of Income, compared to $1.7 million in the second quarter of 2018 and $3.1 million in the third quarter of 2017. The third quarter of 2018 also included expense related to our efforts to implement upgrades to our core operating systems of $2.7 million, compared to $3.2 million in the second quarter of 2018, and none in the third quarter of 2017. In addition, the third quarter of 2018 included $0.9 million of early lease termination expense resulting from the consolidation of office space housing our wealth management unit, which is expected to result in approximately $450 thousand of occupancy expense savings annually. Excluding the impact of federal historic tax credits, core operating system conversion expense, lease termination costs and merger and restructuring expense, the increase in operating expenses in the third quarter of 2018, compared to both the second quarter of 2018 and the third quarter of 2017, was primarily due to increases in salaries, wages and employee benefits and outside processing and service fees. Excluding core operating system conversion expenses included within salaries, wages and employee benefits of $0.7 million in the third quarter of 2018 and $0.5 million in the second quarter of 2018, salaries, wages and employee benefits in the third quarter of 2018 increased $0.5 million compared to the second quarter of 2018, and increased $3.6 million compared to the third quarter of 2017, primarily due to increases in staff to support our strategic focus on commercial lending growth opportunities. The increase in outside processing and service fees in the third quarter of 2018, compared to both the second quarter of 2018 and the third quarter of 2017, was primarily due to substantial enhancements in our overall technology platform.

Our efficiency ratio is a measure of operating expenses as a percentage of net interest income and noninterest income. Our efficiency ratio was 55.6% in the third quarter of 2018, compared to 53.5% in the second quarter of 2018 and 68.0% in the third quarter of 2017. Our adjusted efficiency ratio, a non-GAAP financial measure, which excludes, as applicable, amortization of intangibles, merger and restructuring expenses, impairment of income tax credits, the net interest income FTE adjustment, the change in fair value on loan servicing rights, and losses from sale of investment securities, was 52.8% in the third quarter of 2018, compared to 51.2% in both the second quarter of 2018 and the third quarter of 2017.⁽¹⁾

Our total loans were $14.80 billion at September 30, 2018, an increase of $216.6 million, from total loans of $14.58 billion at June 30, 2018 and an increase of $962.9 million, from total loans of $13.83 billion at September 30, 2017. We experienced originated loan growth of $448.9 million during the third quarter of 2018, compared to $684.0 million in the second quarter of 2018 and $496.5 million in the third quarter of 2017. Growth in our originated loan portfolio was partially offset by run-off in our acquired loan portfolio of $232.4 million in the third quarter of 2018, compared to $323.1 million in the second quarter of 2018 and $330.5 million in the third quarter of 2017.

Our total deposits increased to $15.44 billion at September 30, 2018, compared to $14.55 billion at June 30, 2018 and $13.81 billion at September 30, 2017. The increase in deposits during the three months ended September 30, 2018 was primarily due to an increase in customer deposits of $1.07 billion, partially offset by a decrease in brokered deposits of $172.6 million. Collateralized customer deposits were $377.5 million at September 30, 2018, compared to $378.9 million at June 30, 2018 and $414.6 million at September 30, 2017. Loans as a percentage of deposits plus collateralized customer deposits were 93.5% at September 30, 2018, compared to 97.7% at June 30, 2018 and 97.3% at September 30, 2017.

Our shareholders' equity to total assets ratio was 13.3% at September 30, 2018, compared to 13.6% at June 30, 2018 and 13.8% at September 30, 2017. Our tangible shareholders' equity to tangible assets ratio, a non-GAAP financial measure, and total risk-based capital ratio were 8.3% and 11.7% (estimated), respectively, at September 30, 2018 compared to 8.3% and 11.4%, respectively, at June 30, 2018 and 8.3% and 11.2%, respectively, at September 30, 2017.⁽¹⁾ Our book value was $39.04 per share at September 30, 2018, compared to $38.52 per share at June 30, 2018 and $37.57 per share at September 30, 2017. Our tangible book value, a non-GAAP financial measure, was $22.87 per share at September 30, 2018, compared to $22.33 per share at June 30, 2018 and $21.36 per share at September 30, 2017.⁽¹⁾
