"Our third quarter performance was exceptionally strong, supported by core earnings growth that reflects margin expansion and disciplined operating expense control," stated Ronald L. Zimmerly, Jr., President and Chief Executive Officer. "These results, combined with steady asset growth and strong asset quality, demonstrate the strength of our community banking model and our commitment to serving customers across our markets. Solid third quarter financial results have driven year-to-date earnings per diluted share to $2.01, increased book value by 6.1% to $27.71 per share, and produced a return on average assets of 1.14%, compared to 0.77% a year ago."

"Continued investments in our operations and talent have strengthened our foundation and positioned Middlefield for sustained performance and shareholder value creation. The relocation of our Westerville office remains on track to open in the fourth quarter of 2025, advancing our multi-year strategy to expand our presence in the Central Ohio region. As we look to the remainder of the year, we are confident 2025 will be another year of profitable growth and progress," concluded Mr. Zimmerly.

Income Statement

Net interest income for the 2025 third quarter increased 16.5% to $17.6 million, compared to $15.1 million for the 2024 third quarter. The net interest margin for the 2025 third quarter was 3.79%, compared to 3.46% for the same period of 2024. Net interest income for the nine months ended September 30, 2025, increased 13.2% to $51.1 million, compared to $45.1 million for the same period last year. The increase was primarily due to strong loan growth, a decrease in FHLB advances, a decline in the rates for FHLB advances, and an overall decline in rates for deposits despite an increase in total deposit balances. Net interest margin for the nine months ended September 30, 2025, was 3.79%, compared to 3.51% for the same period last year.

Noninterest income for the 2025 third quarter was $2.3 million, compared to $1.7 million for the same period the previous year. For the nine months ended September 30, 2025, noninterest income increased $2.0 million to $7.3 million, compared to $5.3 million for the same period in 2024. In April 2025, Middlefield completed an exchange of real estate with the City of Westerville, Ohio for a parcel of land that had a fair value of $1.5 million. In exchange, Middlefield transferred land and a building with related furnishings associated with its current branch located in Westerville, Ohio. The transferred branch had a net book value of $221,000. The exchange of real estate transaction resulted in a one-time, non-cash gain of $1.2 million during the second quarter of 2025.

For the 2025 third quarter, noninterest expense was $13.1 million, compared to $11.9 million for the 2024 third quarter. Noninterest expense for the nine months ended September 30, 2025, was $38.9 million, compared to $35.7 million for the same period in 2024. Noninterest expense for the 2025 second quarter included a $700,000 loss associated with recording a separate property located in Westerville, Ohio as held for sale.

Net income for the 2025 third quarter was $5.3 million, or $0.65 per diluted share, compared to $2.3 million, or $0.29 per diluted share, for the same period last year. Net income for the nine months ended September 30, 2025, was $16.3 million, or $2.01 per diluted share, compared to $10.7 million, or $1.32 per diluted share, for the same period last year.

Balance Sheet

Total assets at September 30, 2025, increased 6.5% to a record $1.98 billion, compared to $1.86 billion at September 30, 2024. Total loans at September 30, 2025, were a record $1.61 billion, compared to $1.50 billion at September 30, 2024. The 6.8% year-over-year increase in total loans was primarily due to higher commercial and industrial loans, owner occupied, home equity lines of credit, and residential real estate loans, partially offset by a reduction in non-owner occupied, construction and other, and multifamily loans.

The investment securities available-for-sale portfolio was $155.9 million at September 30, 2025, compared with $169.9 million at September 30, 2024.

Total liabilities at September 30, 2025, increased 6.5% to $1.75 billion, compared to $1.65 billion at September 30, 2024. Total deposits at September 30, 2025, were $1.62 billion, compared to $1.51 billion at September 30, 2024. The 7.2% year-over-year increase in deposits was primarily due to growth in money market deposits, partially offset by a decline in time deposit accounts. Noninterest-bearing demand deposits were 25.3% of total deposits at September 30, 2025, compared to 25.8% at September 30, 2024. At September 30, 2025, the Company had brokered deposits of $108.6 million, compared to $86.5 million at September 30, 2024.

Michael C. Ranttila, Chief Financial Officer, stated, "Throughout the year we have been focused on growing core deposits by improving the mix of commercial and industrial loans and growing treasury management relationships. As a result of these strategies, commercial and industrial loans have been the largest contributor to loan growth since September 2024. At September 30, 2025, commercial and industrial loans have increased $56.3 million, or 26.4% year-over-year. Increasing commercial and industrial relationships have helped support core deposit growth, which at September 30, 2025, has increased 6.1% compared to the same period a year ago."

Stockholders' Equity and Dividends

At September 30, 2025, stockholders' equity was $224.1 million, compared to $210.7 million at September 30, 2024. The 6.4% year-over-year increase in stockholders' equity was primarily from higher retained earnings, partially offset by an increase in the unrealized losses on the available-for-sale investment portfolio. On a per-share basis, shareholders' equity at September 30, 2025, was $27.71, compared to $26.11 at September 30, 2024.

At September 30, 2025, tangible stockholders' equity⁽¹⁾ was $182.9 million, compared to $168.5 million at September 30, 2024. On a per-share basis, tangible stockholders' equity⁽¹⁾ was $22.62 at September 30, 2025, compared to $20.87 at September 30, 2024. ⁽¹⁾See non-GAAP reconciliation under the section "GAAP to Non-GAAP Reconciliations".

For the nine months ended September 30, 2025, the Company declared cash dividends of $0.63 per share, totaling $5.1 million. Beginning in the first quarter of 2025, the Company increased the quarterly cash dividend by $0.01, or 5% from the previous year's $0.20 per share quarterly cash dividend.

For the nine months ended September 30, 2025, the Company did not repurchase any shares of its common stock.

At September 30, 2025, the Company's equity-to-assets ratio was 11.33%, compared to 11.34% at September 30, 2024.

Asset Quality

For the 2025 third quarter, the Company recorded a provision for credit losses of $392,000, compared to a provision for credit losses of $2.2 million for the 2024 third quarter. For the nine months ended September 30, 2025, the Company recorded a recovery of credit losses of $19,000, compared to a provision for credit losses of $2.2 million for the same period of 2024.

Net recoveries were $334,000, or (0.03%) of average loans, annualized, for the nine months ended September 30, 2025, compared to net charge-offs of $1.3 million, or 0.11% of average loans, annualized, for the same period of 2024.

Nonperforming loans at September 30, 2025, were $29.9 million, which is consistent with nonperforming loans of $30.1 million at September 30, 2024. The allowance for credit losses at September 30, 2025, stood at $23.0 million, or 1.43% of total loans, compared to $22.5 million, or 1.50% of total loans at September 30, 2024. While the allowance for credit losses has remained flat year-over-year, the percentage of the allowance for credit losses to total loans has decreased as a result of an overall increase in total loans while maintaining strong credit quality within the portfolio.

Mr. Ranttila continued, "Nonperforming assets to total assets improved to 1.51% at September 30, 2025, compared to 1.62% at September 30, 2024, reflecting improving asset quality on a year-over-year basis. The modest increase in nonperforming assets from the prior quarter was primarily attributable to two commercial real estate loans, and one commercial and industrial loan. Combined, these loans represented approximately $5.6 million of the increase. We are actively working with these borrowers and expect a favorable resolution in the coming quarters. We believe these relationships are not indicative of a trend in the markets we serve, our portfolio, or our underwriting standards. Overall, we remain encouraged by the strength of our portfolio, ongoing loan and deposit growth, and the year-over-year improvement in net interest margin. We believe these positive trends will continue through the remainder of 2025."
