MIDDLEFIELD, Ohio, July 16, 2021 (GLOBE NEWSWIRE) -- Middlefield Banc Corp. (NASDAQ:MBCN) today reported financial results for the 2021 first half and second quarter ended June 30, 2021.

2021 First Half Financial Highlights Include (on a year-over-year basis unless noted):

Net income of $8.6 million, or $1.35 per diluted share driven by record second quarter earnings of $4.4 million, or a record $0.70 per diluted share
Net interest margin improved by 16 basis points to 3.72%, compared to 3.56%
Total noninterest income was up 49.9% to $3.9 million
Pre-tax, pre-provision⁽¹⁾ income increased 35.4% to $11.4 million
Return on average assets increased to 1.26% from 0.64%
Return on average equity increased to 11.88% from 5.79%
Return on average tangible common equity⁽¹⁾ increased to 13.41% from 6.59%
Efficiency ratio improved to 57.60%, compared to 62.33%
Year-to-date net charge-offs declined 46.6% to $159,000

"Our record second quarter and first half earnings reflect strong operating performance across our business and improving economic trends throughout our Northeast and Central Ohio markets," stated Thomas G. Caldwell, President and Chief Executive Officer. "In addition, we have successfully navigated the low interest rate environment throughout the 2021 first half by successfully managing our net interest margin, enhancing our efficiency ratio, controlling operating expenses, growing noninterest income, and maintaining strong asset quality."

"Year-to-date, we have helped small business customers secure $93.5 million of PPP forgiveness, which provided a $1.5 million benefit to our yield on earnings assets. At June 30, 2021, $90.2 million of PPP loans remained on the balance sheet and we expect the majority of the outstanding PPP loans will be forgiven by year end."

"While economic and interest rate uncertainty remains, we are focused on pursuing our long-term growth strategy, making investments across our business, and creating value for our shareholders. As a result, we recently hired two new loan officers in Central Ohio, we are improving our customer engagement by enhancing the Bank's online resources and returning capital to shareholders through our higher year-over-year dividend payment and share buyback program. Year-to-date, we have repurchased 181,045 shares of our common stock at an average price of $23.16 per share, which includes 131,577 shares repurchased in the second quarter at an average price of $23.42 per share. We have repurchased our common stock at an average price of 111.2% to tangible book value, which we believe is a tremendous value and offers a significant opportunity for our shareholders to increase their ownership in Middlefield Banc Corp. Overall, I am pleased with our strong year-to-date performance, and we expect 2021 will be another strong year for the Company," concluded Mr. Caldwell.

Income Statement

Net interest income for the 2021 first half, increased 14.6% to $23.8 million, compared to $20.8 million for the same period last year. Year-to-date, the net interest margin was 3.72%, compared to 3.56% for the same period last year. Net interest income for the 2021 second quarter was $11.9 million, compared to $10.7 million for the 2020 second quarter. The 10.8% increase in net interest income for the 2021 second quarter was largely a result of a 56.8% reduction in interest expense. The net interest margin for the 2021 second quarter was 3.72%, compared to 3.49% for the same period of 2020.

For the 2021 first half, noninterest income was $3.9 million, compared to $2.6 million for the same period last year. Noninterest income for the 2021 second quarter was $1.6 million, compared to $1.5 million for the same period last year.

For the 2021 first half, noninterest expense increased 9.0% to $16.3 million, compared to $14.9 million for the same period last year. Operating costs in the 2021 second quarter increased 3.1% to $7.9 million from $7.7 million for the 2020 second quarter.

Net income for the 2021 first half ended June 30, 2021, was a record $8.6 million, or a record $1.35 per diluted share, compared to $4.0 million, or $0.62 per diluted share for the same period last year. Net income for the 2021 second quarter ended June 30, 2021, was a quarterly record of $4.4 million, or $0.70 per diluted share, compared to $3.0 million, or $0.46 per diluted share for the same period last year.

Balance Sheet

Total assets at June 30, 2021, increased 1.3% to approximately $1.36 billion from $1.34 billion at June 30, 2020. Net loans at June 30, 2021, decreased 5.3% to $1.04 billion, compared to $1.10 billion at June 30, 2020 as PPP forgiveness increased. Middlefield originated $212.6 million of loans under the PPP and helped customers receive $122.4 million of forgiveness payments under the terms of the program. The balance of PPP loans outstanding at June 30, 2021, was $90.2 million.

Total deposits at June 30, 2021, were approximately $1.20 billion, compared to $1.16 billion at June 30, 2020. The 3.2% increase in deposits was primarily due to increases in interest-bearing, money market, savings, and non-interest-bearing accounts, partially offset by decreased time-based accounts. At June 30, 2021, Middlefield had no short-term borrowings compared to $20.4 million of short-term borrowings at June 30, 2020 as the Company paid back Federal Home Loan Bank advances. The investment portfolio, which is entirely classified as available for sale, was $150.9 million June 30, 2021, compared with $112.5 million at June 30, 2020.

Donald L. Stacy, Chief Financial Officer stated, "Our balance sheet remains strong as we benefit from record earnings, favorable asset quality, and a meaningfully higher allowance. The allowance for loan losses to total loans now stands at 1.34%, compared to 1.28% at March 31, 2021, and 0.92% at June 30, 2020. In addition, at June 30, 2021, we only had eight loans in deferral status primarily within the hospitality industry representing a balance of $17.7 million, compared to a balance of $214.8 million at June 30, 2020, a decline of approximately 92%."

"We also ended the quarter with robust capital levels and liquidity, including nearly $92.5 million in cash and cash equivalents and $150.9 million in our investment portfolio. We are focused on maximizing the yield on our investment portfolio, while prudently managing risk. As a result, our investment portfolio includes $32 million of subordinated debt, at an average yield of approximately 4.8%, in community banks across the country with similar metrics. The remainder of our investment portfolio is primarily held in tax free municipal bonds. I believe our record year-to-date financial results demonstrate strong execution across many aspects of the Bank and our ability to focus on managing items under our control," concluded Mr. Stacy.

Stockholders' Equity and Dividends

At June 30, 2021, shareholders' equity increased 3.8% to $146.0 million compared to $140.7 million at June 30, 2020. On a per share basis, shareholders' equity at June 30, 2021, was $23.50 compared to $22.09 at the same period last year.

Tangible stockholders' equity⁽¹⁾ increased 4.6% to $129.4 million for the 2021 second quarter, compared to $123.7 million at June 30, 2020. On a per-share basis, tangible stockholders' equity⁽¹⁾ was $20.82 at June 30, 2021, compared to $19.43 at June 30, 2020.

Through the first six months of 2021, the Company declared cash dividends of $0.32 per share, compared to $0.30 per share for the same period last year.

At June 30, 2021, the Company had an equity to assets leverage ratio of 10.74%, compared to 10.47% at June 30, 2020.

Asset Quality

The provision for loan losses for the 2021 second quarter was $200,000 versus $1.0 million for the same period last year. The year-over-year decline in the provision for loan losses was partially due to strong asset quality and last year's prudent build in the Company's allowance for loan losses associated with the potential economic impacts caused by the COVID-19 pandemic. The provision for loan losses for the 2021 first half was $900,000 versus $3.7 million for the same period last year.

Net charge-offs were $122,000, or 0.05% of average loans, annualized, during the 2021 second quarter, compared to net charge-offs of $34,000, or 0.01% of average loans, annualized, at June 30, 2020. Year-to-date net charge-offs were $159,000, or 0.03% of average loans, annualized, compared to net charge-offs of $298,000, or 0.06% of average loans, annualized for the six-months ended June 30, 2020.

Nonperforming assets at June 30, 2021, were $14.9 million, compared to $10.5 million at June 30, 2020. The $4.4 million increase in nonperforming assets was affected by one large legacy credit in the Central Ohio market, which was charged-off during the 2020 third quarter. Nonperforming loans at June 30, 2021 were $7.8 million a 20.8% decline from the same period last year, and a 13.4% decline from the 2021 first quarter. The allowance for loan losses at June 30, 2021, stood at $14.2 million, or 1.34% of total loans, compared to $10.2 million, or 0.92% of total loans at June 30, 2020.
