Ronald L. Zimmerly, Jr., President and Chief Executive Officer, stated, “2024 is off to a solid start. Over the past three months, our pre-tax, pre-provision income⁽¹⁾ stabilized, reflecting positive loan growth, strong asset quality, higher noninterest income, and controlled operating expenses. During this period, our ROAA, ROAE, and ROATCE increased due to improved profitability. In addition, we ended the quarter with record total loans as our expanded Commercial, Business, and Consumer Banking teams capitalized on favorable demand trends across our Northeast, Central, and Western Ohio markets.”

“While we expect uncertainty about FOMC monetary policies and their impact on national economic conditions in 2024 to continue, economic activity and employment within our Ohio markets are stable. In addition, our asset quality remains excellent, and nonperforming assets at the end of the first quarter improved slightly from the fourth quarter and were down 14.5% from last year’s first quarter. Our first quarter performance is encouraging and reflects our teams’ hard work and contributions across our three Ohio markets. As we look to the remainder of the year, we are focused on pursuing our multi-year strategic growth goals: increasing revenue opportunities, improving our customer experience, and advancing operational performance to create lasting value for our shareholders,” concluded Mr. Zimmerly.

Income Statement

Net interest income for the 2024 first quarter decreased 9.3% to $15.0 million, compared to $16.5 million for the same period last year. The net interest margin for the 2024 first quarter was 3.53%, compared to 4.19% last year.

For the 2024 first quarter, noninterest income increased 6.9% to $1.8 million, compared to $1.7 million for the same period of 2023.

Noninterest expense for the 2024 first quarter was $12.0 million, compared to $11.8 million for the 2023 first quarter.

Net income for the 2024 first quarter ended March 31, 2024, was $4.2 million, or $0.51 per diluted share, compared to $4.9 million, or $0.60 per diluted share, for the same period last year.

For the 2024 first quarter, pre-tax, pre-provision net income was $4.8 million, compared to $6.4 million last year. (See non-GAAP reconciliation under the section “GAAP to Non-GAAP Reconciliations”).

Balance Sheet

Total assets at March 31, 2024, increased 5.1% to $1.82 billion, compared to $1.73 billion at March 31, 2023. Total loans at March 31, 2024, were $1.49 billion, compared to $1.38 billion at March 31, 2023. The 7.8% year-over-year increase in total loans was primarily due to higher commercial and industrial, residential real estate, commercial real estate, and construction and other loans.

Total liabilities at March 31, 2024, increased 5.1% to $1.61 billion, compared to $1.53 billion at March 31, 2023. Total deposits at March 31, 2024, were $1.45 billion, compared to $1.43 billion at March 31, 2023. The 1.5% year-over-year increase in deposits was primarily due to growth in money market, interest-bearing demand, and time deposits, partially offset by declines in noninterest-bearing demand and savings accounts. Noninterest-bearing demand deposits were 27.0% of total deposits at March 31, 2024, compared to 33.3% at March 31, 2023. At March 31, 2024, the Company had brokered deposits of $90.4 million, compared to $5.0 million at March 31, 2023.

The investment securities available for sale portfolio was $167.9 million at March 31, 2024, compared with $169.6 million at March 31, 2023.

Michael Ranttila, Chief Financial Officer, stated, “Asset quality improved on both a sequential and year-over-year basis, reflecting our conservative underwriting standards and balanced portfolio composition. Nonperforming loans at March 31, 2024, included one self-storage loan in the Southwest Ohio market totaling $3.6 million. We believe this issue is isolated to this borrower and does not indicate a trend in the market, our portfolio, or an issue in underwriting.”

Mr. Ranttila continued, “We also remain focused on identifying opportunities to improve our cost of funds, pay down higher cost capital, and grow core deposits to support loan demand. Over the past three months, total deposits increased 1.4%, while our Federal Home Loan Bank advances decreased by nearly 16.0%. With sufficient liquidity, stabilizing profitability, and excellent asset quality, I am pleased to report that during the first quarter, we repurchased 43,858 shares of our common stock at an average price of $24.00 per share, reflecting our long-standing commitment to return excess capital to shareholders.”

Middlefield’s CRE portfolio included the following categories at March 31, 2024:

Stockholders’ Equity and Dividends

At March 31, 2024, stockholders’ equity was $205.6 million compared to $195.2 million at March 31, 2023. The 5.3% year-over-year increase in stockholders’ equity was primarily due to higher retained earnings and an improvement in the unrealized losses on the available-for-sale investment portfolio, partially offset by the Company’s stock repurchase program. On a per-share basis, shareholders’ equity at March 31, 2024, was $25.48 compared to $24.13 at March 31, 2023.

At March 31, 2024, tangible stockholders’ equity⁽¹⁾ was $162.8 million, compared to $156.0 million at March 31, 2023. On a per-share basis, tangible stockholders’ equity⁽¹⁾ was $20.18 at March 31, 2024, compared to $19.29 at March 31, 2023. ⁽¹⁾See non-GAAP reconciliation under the section “GAAP to Non-GAAP Reconciliations”.

For the 2024 first quarter, the Company declared cash dividends of $0.20 per share, totaling $1.6 million.

At March 31, 2024, the Company’s equity-to-assets ratio was 11.32%, compared to 11.30% at March 31, 2023.

Asset Quality

For the 2024 first quarter, the Company recorded a recovery of credit losses of $100,000 versus a provision for credit losses of $500,000 for the same period last year.

Net recoveries were $68,000, or 0.02% of average loans, annualized, during the first quarter of 2024, compared to net recoveries of $8,000, or 0.00% of average loans, annualized, at March 31, 2023.

Nonperforming loans at March 31, 2024, were $10.8 million, compared to $6.9 million at March 31, 2023. Nonperforming assets at March 31, 2024, were $10.8 million, compared to $12.7 million at March 31, 2023. The allowance for credit losses at March 31, 2024, stood at $21.1 million, or 1.41% of total loans, compared to $20.2 million, or 1.46% of total loans at March 31, 2023. The decrease in the allowance for credit losses as a percentage of total loans was mainly due to changes in projected loss drivers, prepayment assumptions, and curtailment expectations over the reasonable and supportable forecast period.
