shares at an average price of $26.67 per share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income was $15.7 million, or $2.59 per diluted share, compared to $18.6 million, or $3.00 per
diluted share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-GAAP<sup>(1)</sup> net income, adjusted for certain one-time items and expenses associated with the Liberty Bancshares, Inc. merger, was $18.3 million, or $3.03 per diluted share, compared to $18.5 million, or $2.98 per diluted share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-GAAP<sup>(1)</sup> ROAE and ROATE, adjusted for certain one-time items and expenses associated with the Liberty Bancshares, Inc. merger, was 13.15% and 15.12%, respectively, compared to 12.65% and 14.27%, respectively

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Twelve-month pre-tax income benefited from $1.2 million of net fees
associated with the Paycheck Protection Program ("PPP"), compared to $1.1 million in the 2021 full year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net interest margin improved by 30 basis points to 4.08%, compared to 3.78%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total loans were $1.35 billion, compared to $981.7 million at December 31, 2021

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total loans increased organically by $91.4 million, or 9.6% from December 31, 2021, without the impact

"Middlefield experienced another excellent year of core earnings driven by a 4.08% net interest margin, a 9.6% increase in organic loans, and robust asset quality. These results reflect the execution of our strategic plan, the dedication of our skilled team members, and the value we provide our local communities. In

------

addition, we completed the Liberty Bancshares merger during the 2022 fourth quarter, which increased our scale and exposure in the Central and Northwest Ohio regions. We are delighted to bring our common philosophies to customers within these markets. Over the next several months, we will focus on integrating Liberty into Middlefield's organization," stated James R. Heslop, II, Chief Executive Officer.

"Our performance during 2022 was encouraging as we overcame the Federal Reserve's rapid increase in interest rates, growing competition for deposits and increased economic uncertainty. While we expect these trends to continue throughout 2023, we are well-positioned to navigate a more challenging landscape due to our strong capital position, excellent asset quality and favorable net interest margin. Most importantly, our solid financial position allows us to support our local communities during an increasingly complex operating environment while continuing to focus on creating value and returning capital to our shareholders," concluded Mr. Heslop.

**Income Statement** 

Net interest income for the twelve-months ended December 31, 2022, was $50.2 million, an increase of $2.1 million or 4.2%, compared to $48.1 million last year. The net interest margin for the 2022 twelve-month period was 4.08%, compared to 3.78% for the same period the previous year. Net interest income for the 2022 fourth quarter was $14.1 million, compared to $12.0 million for the 2021 fourth quarter. The 17.7% increase in net interest income for the 2022 fourth quarter from the same period in 2021 was primarily a result of higher interest income. The net interest margin for the 2022 fourth quarter was 4.23%, compared to 3.81% for the same period of 2021.

For the 2022 twelve-month period, noninterest income was $6.7 million, compared to $7.2 million, a decrease of $460,000 or 6.4%, for the same period last year. Noninterest income for 2022 benefitted from $951,000 of gross rental income related to leasing other real estate owned, mostly offset by $686,000 of related gross rental expense. Noninterest income for the 2022 fourth quarter was $2.4 million, compared to $1.5 million for the same period last year.

For the 2022 twelve-month period, noninterest expense increased $6.1 million, or 19.0%, to $38.0 million, compared to $31.9 million for the same period last year. Operating costs in the 2022 fourth quarter increased 57.6% to $12.3 million from $7.8 million for the 2021 fourth quarter. The Company incurred $1.4 million of additional operating expenses associated with the Liberty Bancshares, Inc. merger during the 2022 fourth quarter and $2.4 million during the 2022 twelve-month period. In addition, the Company incurred a net loss on other real estate owned of $1.7 million during the 2022 fourth quarter mostly due to the write-down of an other real estate asset.

Net income for the 2022 twelve-month period was $15.7 million, or $2.59 per diluted share, compared to $18.6 million, or $3.00 per diluted share, for the same period last year. Non-GAAP<sup>(1)</sup> net income, adjusted for certain one-time items and expenses associated with the Liberty Bancshares, Inc. merger, was $18.3 million, or $3.03 per diluted share for the 2022 twelve-month period, compared to $18.5 million, or $2.98 per diluted share for the same period last year.

**Balance Sheet** 

Total assets at December 31, 2022, increased to approximately $1.69 billion from $1.33 billion at December 31, 2021. The $356.6 million, or 26.8%, year-over-year increase in total assets was primarily due to the Liberty Bancshares, Inc. merger. Net loans at December 31, 2022, increased 38.4% to $1.34 billion,

------

compared to $967.3 million at December 31, 2021. On an organic basis, without the impact of PPP loan forgiveness and the Liberty Bancshares, Inc. merger, total loans at December 31, 2022, increased 9.6%, compared to December 31, 2021.

Since 2020, Middlefield has helped customers receive $211.8 million of forgiveness payments under the terms of the Paycheck Protection Program, including processing $33.4 million of forgiveness payments for the 2022 full year. The balance of PPP loans outstanding at December 31, 2022, was $0.7 million.

Total deposits at December 31, 2022, were $1.40 billion, compared to $1.17 billion at December 31, 2021. The 20.2% increase in deposits was primarily due to the Liberty Bancshares, Inc. merger. On an organic basis, total deposits at December 31, 2022, decreased 7.8% compared to December 31, 2021. The investment portfolio was $165.0 million at December 31, 2022, compared with $170.2 million at December 31, 2021.

Donald L. Stacy, Chief Financial Officer, stated, "While we expect an increase in the cost of funds to pressure net interest margin in future quarters, we entered this period with the highest net interest margin since 2000. Asset quality remains strong across our portfolio, as nonperforming loans to total loans were just 0.52% at December 31, 2022, compared to 0.49% at December 31, 2021."

Mr. Stacy continued, "With a net loan-to-deposit ratio of 95.5%, $53.8 million in cash and cash equivalents, and $165.0 million in investment securities at December 31, 2022, we believe we have ample liquidity and capital levels to support our long-term growth strategies, dividend payment, and share repurchase program. Since January 2019, we have repurchased 898,901 shares, representing 13.9% of the outstanding shares prior to our repurchase program. This includes 229,420 shares repurchased during 2022 at an average of $26.67 per share."

**Stockholders' Equity and Dividends** 

At December 31, 2022, stockholders' equity was $197.7 million compared to $145.3 million at December 31, 2021. The 36.0% year-over-year increase in stockholders' equity was primarily due to the Liberty Bancshares, Inc. merger, partially offset by an increase in the unrealized loss on the available-for-sale investment portfolio and the Company's stock repurchase program. On a per-share basis, shareholders' equity at December 31, 2022, was $23.98 compared to $24.68 at December 31, 2021.

Tangible stockholders' equity<sup>(1)</sup> was $158.3 million for December 31, 2022, compared to $128.9 million at December 31, 2021. On a per-share basis, tangible stockholders' equity<sup>(1)</sup> at December 31, 2022, was $19.19, compared to $21.88 at December 31, 2021.

For the 2022 full year, cash dividends declared per share increased 17.4% to $0.81 totaling $5.5 million, compared to $0.69 per share or $4.2 million for the same period last year. Dividends in 2022 included a $0.10 per share one-time dividend payment declared in the fourth quarter.

At December 31, 2022, the Company had an equity-to-assets leverage ratio of 11.71%, compared to 10.92% at December 31, 2021. The year-over-year increase in the Company's equity-to-assets leverage ratio occurred even as Middlefield invested $6.1 million in its share repurchase program.

**Asset Quality** 

No provision for loan losses was recorded for the 2022 fourth quarter, compared to a net loan loss recovery of $200,000 for the 2021 fourth quarter. There was no provision for loan losses for the 2022 full year period versus a $700,000 provision for loan losses for the same period last year.

Net charge-offs were $94,000, or 0.03% of average loans, annualized, during the 2022 fourth quarter, compared to net recoveries of $308,000 for the same quarter last year. For the 2022 full year, net recoveries were $96,000, or 0.01% of average loans, compared to net recoveries of $183,000, or 0.02% of average loans for the full year ended December 31, 2021.

------

Nonperforming assets at December 31, 2022, were $12.8 million, compared to $11.9 million at December 31, 2021. Nonperforming loans at December 31, 2022, were $7.0 million, compared to $4.9 million at December 31, 2021 primarily due to the Liberty Bancshares, Inc. merger. The allowance for loan losses at December 31, 2022, stood at $14.4 million, or 1.07% of total loans, compared to $14.3 million, or 1.46% of total loans at December 31, 2021.
