Second Quarter 2023 Results

HOLLAND, Mich. (July 27, 2023) – Macatawa Bank Corporation (NASDAQ: MCBC), the holding company for Macatawa Bank (collectively, the “Company”), today announced its results for the second quarter 2023.

The Company reported net income of $10.3 million, or $0.30 per diluted share, in second quarter 2023 compared to $6.6 million, or $0.19 per diluted share, in second quarter 2022. For the first six months of 2023, the Company reported net income of $22.3 million, or $0.65 per diluted share, compared to $12.6 million, or $0.37 per diluted share, for the same period in 2022.

"We are pleased to report strong profitability and good balance sheet results for the second quarter 2023,” said Ronald L. Haan, President and CEO of the Company. “Net interest income for second quarter 2023 was up $6.3 million from second quarter 2022, reflecting benefits from federal funds rate increases and growth in our loan and investment securities portfolios. We remain encouraged by our loan origination activity while maintaining excellent credit quality. We have seen some shifting in our deposits to higher interest bearing types, particularly certificates of deposit, which has a downward impact on net interest margin, but our core deposit balances remain well above pre-pandemic levels and decreased only slightly in the second quarter 2023 in the wake of the highly publicized bank failures in early March of this year.”

Mr. Haan concluded: "We believe our balance sheet is well positioned in the current environment. High levels of liquidity, capital, and excellent asset quality put us in a good position to weather softer economic conditions, should they occur, and to seize loan growth opportunities in our markets. While cautionary signals are ever present and we will undoubtedly face new challenges, we remain committed to building a conservative and well-disciplined company that is focused on using prudent and time tested banking principles to provide strong and consistent financial performance to our shareholders.”

Operating Results

Net interest income for the second quarter 2023 totaled $21.1 million, a decrease of $1.5 million from first quarter 2023 and an increase of $6.3 million from second quarter 2022. Net interest margin for second quarter 2023 was 3.36 percent, down 8 basis points from first quarter 2023 and up 117 basis points from second quarter 2022. Net interest income in second quarter 2023 versus second quarter 2022 benefited from the significant increases in the federal funds rate which totaled 350 basis points between July 2022 and June 2023 and the related increases in rate indices impacting the Company’s variable rate loan portfolios. Interest on commercial loans increased $5.8 million in the second quarter 2023 compared to second quarter 2022 due to increases in both rate and average portfolio balances. Interest on federal funds in the second quarter 2023 increased by $2.9 million compared to second quarter 2022 due to higher rates paid on lower average balances held. Net interest income also benefited from growth in the investment securities portfolio to further deploy excess liquid funds held by the Company. Interest on investment securities in the second quarter 2023 increased by $2.0 million over second quarter 2022. Interest expense totaled $6.0 million in the second quarter 2023 compared to $592,000 in the second quarter 2022 as rates paid on deposits increased.

Non-interest income increased $85,000 in second quarter 2023 compared to first quarter 2023 and decreased $518,000 from second quarter 2022. Brokerage income was down $133,000 in second quarter 2023 compared to first quarter 2023 and was down $67,000 compared to the second quarter 2022. The rising rate environment continued to have a negative effect on mortgage loan sales gains. Gains on sales of mortgage loans in second quarter 2023 were just $21,000, up $10,000 compared to first quarter 2023 and were down $178,000 from second quarter 2022. The Company originated $2.4 million in mortgage loans for sale in second quarter 2023 compared to $179,000 in first quarter 2023 and $8.4 million in second quarter 2022. Trust fees were up $103,000 in second quarter 2023 compared to first quarter 2023 and were up $39,000 compared to second quarter 2022, due largely to improvement in underlying trust asset valuations. Income from debit and credit cards was up $78,000 in second quarter 2023 compared to first quarter 2023 and was down $21,000 compared to second quarter 2022 due primarily to customer usage behavior. Deposit service charge income, including treasury management fees, was up $23,000 in second quarter 2023 compared to first quarter 2023 and was down $201,000 from second quarter 2022. The increase from first quarter 2023 was due to higher levels of treasury management fees while the decrease from second quarter 2022 was primarily due to higher earnings credits provided on treasury management accounts with the increase in deposit market interest rates.

Non-interest expense was $12.7 million for second quarter 2023, compared to $12.2 million for first quarter 2023 and $11.9 million for second quarter 2022. The largest component of non-interest expense was salaries and benefits expenses. Salaries and benefits expenses were up $145,000 compared to first quarter 2023 and were up $441,000 compared to second quarter 2022. The increase compared to first quarter 2023 and second quarter 2022 was primarily due to a higher level of salary and other compensation resulting from merit adjustments to base pay effective April 1, 2023. The table below identifies the primary components of the changes in salaries and benefits between periods.

Occupancy expenses were down $39,000 in second quarter 2023 compared to first quarter 2023 and were up $27,000 compared to second quarter 2022 due to snow removal costs. Furniture and equipment expenses were up $33,000 compared to first quarter 2023 and were up $76,000 compared to second quarter 2022 due primarily to higher costs associated with equipment and software service contracts. FDIC assessment expense was flat in second quarter 2023 compared to first quarter 2023 and was up $133,000 compared to second quarter 2022, reflecting higher assessments placed on banks by the FDIC beginning in 2023. Data processing expenses were up $51,000 in second quarter 2023 compared to first quarter 2023 and were up $82,000 compared to second quarter 2022 due to higher usage of electronic banking services by the Company’s customers and inflationary increases imposed by vendors. In the first quarter 2023, $356,000 in net gains on sales of other real estate owned were recognized as the Company sold its final other real estate owned property. There were no such sales in second quarter 2023 or in the second quarter 2022. Legal and professional fees were down $77,000 in second quarter 2023 compared to first quarter 2023 and were flat compared to second quarter 2022. The higher level of expense in first quarter 2023 was due to various regulatory compliance matters related to loan and deposit accounts referred to legal counsel during the quarter. Outside services were flat in second quarter 2023 compared to first quarter 2023 and were down by $49,000 compared to second quarter 2022. Other categories of non-interest expense were relatively flat compared to first quarter 2023 and second quarter 2022 due to a continued focus on expense management.

Federal income tax expense was $2.5 million for second quarter 2023, $3.0 million for first quarter 2023, and $1.5 million for second quarter 2022. The effective tax rate was 19.4 percent for second quarter 2023, compared to 19.9 percent for first quarter 2023 and 18.5 percent for second quarter 2022. The increase in the effective tax rate over 2022 was due to higher levels of taxable income from both growth in taxable securities held in our investment portfolio and growth in taxable income from rising interest rates while our tax-exempt income has remained relatively flat.

Asset Quality

The Company adopted ASU 2016-13, Financial Instruments – Credit Losses, commonly referred to as “CECL” on January 1, 2023. The impact on adoption was an increase to the allowance for credit losses of $1.5 million. A provision for credit losses of $300,000 was taken in second quarter 2023. No provision for credit losses was recorded in first quarter 2023 or in second quarter 2022. Net loan recoveries for second quarter 2023 were $15,000, compared to first quarter 2023 net loan recoveries of $33,000 and second quarter 2022 net loan recoveries of $15,000. At June 30, 2023, the Company had experienced net loan recoveries in thirty-two of the past thirty-four quarters. Total loans past due on payments by 30 days or more amounted to $158,000 at June 30, 2023, versus $277,000 at March 31, 2023 and $197,000 at June 30, 2022. Delinquencies at June 30, 2023 were comprised of just two individual loans. Delinquency as a percentage of total loans was just 0.01 percent at June 30, 2023, well below the Company’s peer level. Further, the weighted average loan grade of the Company’s commercial loan portfolio continued to improve, decreasing to 3.46 at June 30, 2023 compared to 3.51 at March 31,2023 and 3.58 at June 30, 2022. An improving loan grade decreases the need for providing for credit losses on this portfolio.

The allowance for credit losses of $17.1 million was 1.35 percent of total loans at June 30, 2023, compared to $16.8 million or 1.38 percent of total loans at March 31, 2023, and $14.6 million or 1.32 percent at June 30, 2022. The coverage ratio of allowance for credit losses to nonperforming loans continued to be strong and significantly exceeded 1-to-1 coverage at 237-to-1 as of June 30, 2023.

At June 30, 2023, the Company's nonperforming loans were $72,000, representing 0.01 percent of total loans. This compares to $75,000 (0.01 percent of total loans) at March 31, 2023 and $90,000 (0.01 percent of total loans) at June 30, 2022. The Company had no other real estate owned and repossessed assets at June 30, 2023 and March 31, 2023, down from $2.3 million June 30, 2022. The Company sold its final other real estate owned property in first quarter 2023, recognizing a net gain of $356,000. Total nonperforming assets, including other real estate owned and nonperforming loans, decreased by $2.4 million from June 30, 2022 to June 30, 2023.

A break-down of non-performing loans is shown in the table below.

Balance Sheet, Liquidity and Capital

Total assets were $2.63 billion at June 30, 2023, a decrease of $6.9 million from $2.64 billion at March 31, 2023 and a decrease of $151.0 million from $2.78 billion at June 30, 2022.

The Company’s investment securities portfolio primarily consists of U.S. treasury and agency securities, agency mortgage backed securities and various municipal securities. Total securities were $853.2 million at June 30, 2023, a decrease of $21.1 million from $874.3 million at March 31, 2023 and an increase of $64.9 million from $788.3 million at June 30, 2022. The overall duration of the Company’s investment securities portfolio at June 30, 2023 is relatively short at less than three years. This provides a reliable source of cash inflows as investment securities mature to support liquidity.

Total loans were $1.27 billion at June 30, 2023, an increase of $50.6 million from $1.22 billion at March 31, 2023 and an increase of $162.5 million, excluding PPP loans, from $1.11 billion at June 30, 2022.

Commercial loans increased by $122.0 million, excluding PPP loans, from June 30, 2022 to June 30, 2023, along with an increase of $39.5 million in the residential mortgage portfolio, and an increase of $1.0 million in the consumer loan portfolio. Within commercial loans, commercial real estate loans increased by $40.5 million and commercial and industrial loans increased by $81.5 million. The loan growth experienced in this time period was the direct result of both new loan prospecting efforts and existing customers beginning to draw more on existing lines and borrow more for expansion of their businesses.

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

Total deposits were $2.32 billion at June 30, 2023, down $9.4 million, or 0.4 percent, from $2.33 billion at March 31, 2023 and down $173.0 million, or 7 percent, from $2.49 billion at June 30, 2022. While the Company experienced an overall decline in deposit balances during the three months ended June 30, 2023, much of this was attributable to balances moving into wealth management accounts at the Bank, so these balances should continue to benefit the Company. The Company experienced very little change in deposit balances following the March 2023 bank failures and resulting banking system disruption.

Macatawa’s deposit base is primarily made up of many small accounts, and balances at June 30, 2023 were comprised of 45% personal customers and 55% business customers. Core deposits - which Management defines as deposits sourced within its local markets - represented 100% of total deposits at June 30, 2023. Total deposit balances of $2.32 billion at June 30, 2023 remained elevated, reflecting a $616.2 million increase, or 36 percent, over pre-pandemic totals of $1.71 billion as of March 31, 2020.

Demand deposits were down $22.9 million at the end of second quarter 2023 compared to the end of first quarter 2023 and were down $267.1 million compared to the end of second quarter 2022. Money market deposits and savings deposits were down $55.6 million from the end of first quarter 2023 and were down $64.7 million from the end of second quarter 2022. Certificates of deposit were up $69.1 million at June 30, 2023 compared to March 31, 2023 and were up $158.7 million compared to June 30, 2022 as customers reacted to increases in market interest rates. All certificates of deposit are to local customers as the Company does not have any brokered deposits at June 30, 2023. The Company continues to be successful at attracting and retaining core local deposit customers. Customer deposit accounts remain insured to the highest levels available under FDIC deposit insurance.

Management has actively pursued initiatives to maintain a strong liquidity position. The Company has had no brokered deposits on balance sheet since December 2011 and continues to maintain significant on-balance sheet liquidity. At June 30, 2023, balances held in federal funds sold and other short-term investments amounted to $343.7 million. In addition, the Company had total additional borrowing capacity, including from the Federal Reserve’s new Bank Term Funding Program, of approximately $964.2 million as of June 30, 2023. Finally, because Management has maintained the discipline of buying shorter-term bond durations in the investment securities portfolio, there are $411.8 million in bond maturities and paydowns coming into the Company in the next 24 months ending June 30, 2025.

The Company's total risk-based regulatory capital ratio at June 30, 2023 was consistent with the ratio at March 31, 2023 and June 30, 2022. Macatawa Bank’s risk-based regulatory capital ratios continue to be at levels considerably above those required to be categorized as “well capitalized” under applicable regulatory capital guidelines. As such, the Bank was categorized as "well capitalized" with $131.4 million in excess capital over well capitalized minimums at June 30, 2023.
