Commenting on the second quarter, Sammie D. Dixon, President and Chief Executive Officer, of Prime Meridian Bank and Prime Meridian Holding Company stated, “We are pleased with our year-to-date performance, particularly our net loan production and growth in mortgage banking revenue.”

“We eagerly await the opening of our next branch in Wakulla County and continue to explore and evaluate expansion and acquisition opportunities. Our forthcoming listing on the OTCQX venue of OTC Markets is also an important step in preparing the Company for execution of its growth strategy.”

“We think the future holds great opportunities, and we are making preparations to take advantage of them as they unfold.”

Earnings Summary

The Company reported net interest income of $2.1 million for the quarter ended June 30, 2015 compared to $1.8 million for the same period a year ago. The net interest margin for the quarter ended June 30, 2015 was 3.91%, compared to 3.55% for the 2014 second quarter. For the six months ended June 30, 2015, net interest income totaled $4.1 million, compared to $3.5 million for the comparable period in 2014, and the net interest margin was 3.91% for the six months ended June 30, 2015, compared to 3.42% a year ago. The increase in net interest income for both periods was driven by higher loan production and modest gains in interest income from securities, partially offset by slight decreases in other interest income. Although there continues to be downward pricing pressure on loans, higher average loan balances as a percentage of total interest earning assets also helped improve the overall yield on interest earning assets, thereby boosting net interest margin in both periods.

For the quarter ended June 30, 2015, the Company reported a $191,000 loan loss provision, compared to a $562,000 provision in the second quarter of 2014. For the six months ended June 30, 2015, the Company recorded a $209,000 loan loss provision, compared to a $591,000 provision for the comparable period in 2014. The higher provision in 2014 was primarily caused by one impaired commercial real estate loan.

Noninterest income for the quarter ended June 30, 2015 increased $75,000 from the same period a year ago and noninterest income for the six months ended June 30, 2015 increased $132,000 over the comparable period in 2014. The increases for the quarter and the six-month period ended June 30, 2015 were predominantly driven by increases in mortgage banking revenue.

Noninterest expense increased $31,000, or 2.0%, to $1.6 million for the three months ended June 30, 2015 compared to the same period a year ago. For the six months ended June 30, 2015, noninterest expense totaled $3.1 million, a $92,000 increase over the comparable period in 2014. The increase in both periods is primarily due to higher occupancy and equipment expense and marketing expense. Although salaries and employee benefits expense decreased in both periods despite growth in the number of employees, the decrease in both periods is explained by a change in our estimated standard deferred loan costs related to loan originations and renewals, which is booked as an offset to salary expense and amortized over the life of the loan.

Balance Sheet

As of June 30, 2015, the Company had grown to $229.3 million in total assets, $199.3 million in deposits, and $171.6 million in portfolio net loans. This compares to $210.4 million in total assets, $184.0 million in deposits, and $151.9 million in portfolio net loans as of December 31, 2014. Growth in assets is primarily due to the growth in our loan portfolio.
