Middlefield Banc Corp. Reports Financial Results for the 2014 Second Quarter

MIDDLEFIELD, OHIO, July 22, 2014 ¿¿¿¿ Middlefield Banc Corp. (OTCQB: MBCN) today reported financial results for the three and six months ended June 30, 2014.

2014 Second Quarter Financial Highlights Include:

• Net interest income increased 5.3% to $5.9 million from $5.6 million for the 2013 second quarter.

• The net interest margin improved to 4.04%, compared to 3.88% for the same period of 2013.

• Tangible stockholders’ equity improved 4.8% from 2014 first quarter, and 11.6% from December 31, 2013.

• Total net loans increased 9.5% from the 2013 second quarter and 1.4% compared to the 2014 first quarter.

• Nonperforming assets declined to $12.9 million from $15.2 million for the 2013 second quarter.

• Tier 1 capital ratio strengthened to 9.31% from 8.49% at June 30, 2013.

“We continue to report strong financial results despite higher operating and regulatory costs,” stated Thomas G. Caldwell, President and Chief Executive Officer. “Throughout 2014 we will be making investments in our business by enhancing our operations, products, and services, and adding senior managers to assist with our growth objectives. These activities may impact the level of profitability over the near term but will have a positive effect on our financial results and customer experience in the coming quarters. Our customers are already experiencing the benefits from the investments we have made in our new website, enhanced on-line banking services, and new mobile banking capabilities.”

Net income for the 2014 second quarter was $1.6 million, or $0.79 per diluted share, compared to net income for the 2013 second quarter of $1.7 million, or $0.83 per diluted share. Net income for the six months ended June 30, 2014 was $3.4 million, or $1.65 per diluted share, compared to net income for the six months ended June 30, 2013 of $3.3 million, or $1.66 per diluted share.

Annualized returns on average equity (“ROE”) and average assets (“ROA”) for the 2014 second quarter were 11.58% and 0.96%, respectively, compared with 12.47% and 1.02% for the 2013 second quarter. ROE and ROA were 12.33% and 1.02%, respectively, for the 2014 six month period, compared with 12.32% and 1.02% for the same period last year.

Mr. Caldwell continued: “As we enter the second half of 2014, we are well positioned to grow our banking franchise. By the end of the third quarter, we will enter the secondary mortgage market, which will enhance our product offerings and increase our noninterest income. While we are excited about our growth opportunities, we remain committed to delivering excellent customer service, increasing value to our shareholders, and managing the company under safe and sound banking principles.”

Income Statement

Net interest income for the 2014 second quarter increased 5.3% to $5.9 million, compared to $5.6 million for the 2013 second quarter. For the 2014 first half, net interest income increased 6.0% to $11.8 million, compared to $11.2 million for the same period last year. The second quarter and first half increases in net interest income were driven by a reduction in funding costs, primarily time deposits. The net interest margin for the 2014 second quarter was 4.04%, compared to 3.88% for the same period of 2013. Year-to-date, the net interest margin was 4.12%, compared to 3.90% for the same period last year.

Noninterest income was up slightly for the 2014 second quarter and down year-to-date. The improvement in the 2014 second quarter was a result of investment securities gains and other income, partially offset by lower service charges on deposits and earnings on bank-owned life insurance.

Noninterest expense for the 2014 second quarter was $4.6 million, an increase of approximately $0.7 million from the 2013 second quarter, primarily a result of higher operating expenses.

“We are proactively investing in our future to diversify our sources of income and offset the impact of historically low interest rates and higher regulatory costs,” said Donald L. Stacy, Chief Financial Officer. “The result will be higher near-term expenses as our growth strategies take time to develop. We are working hard to offset a portion of these higher costs through prudent expense management and proactively controlling our cost of funds.”

Balance Sheet

Total assets at June 30, 2014 increased 3.3% to $668.3 million, from $647.1 million at December 31, 2013. Net loans at June 30, 2014 were approximately $443.0 million, compared to $428.7 million at December 31, 2013. The 3.3% year-to-date increase in net loans was a result of growth across all loan categories led by a 4.2% increase in residential mortgage loans.

Total deposits at June 30, 2014 increased 3.5% to $588.8 million from $568.8 million at December 31, 2013. The investment portfolio, which is entirely classified as available for sale, stood at $165.5 million at June 30, 2014, compared to $157.1 million at December 31, 2013. The increase in investment securities available for sale is primarily a result of the growth in the Bank’s tax-free municipal securities portfolio of $8.0 million.

Stockholders’ Equity and Dividends

Tangible stockholders’ equity increased 13.8% to $54.6 million for the 2014 second quarter, compared to $48.0 million for the 2013 second quarter. On a per share basis, tangible stockholders’ equity increased 12.7% to $26.67 at June 30, 2014 from $23.66 at June 30, 2013. The increase is the result of a higher level of retained earnings and accumulated other comprehensive income, which was offset by cash dividends paid to shareholders.

At June 30, 2014, the company had a Tier 1 leverage ratio of 9.31%, up from 8.49% at June 30, 2013 and 9.15% at March 31, 2014.

During the 2014 second quarter, the company paid cash dividends of $0.26 per share, which equaled the amount paid in the 2013 second quarter. Year-to-date, the company has paid cash dividends of $0.52 per share.

Asset Quality

The provision for loan losses for the 2014 second quarter was $0.1 million, compared to the $0.3 million for the 2013 second quarter. The provision for loan losses for the six months ended June 30, 2014 was $0.3 million, compared to $0.6 million for the same period last year. Net charge-offs for the 2014 six months was $0.2 million, or 0.10% of average loans, annualized. The allowance for loan losses at June 30, 2014 stood at $7.1 million, or 1.58% of total loans, compared to $7.7 million or 1.88% of total loans at June 30, 2013.
