According to Sammie D. Dixon, President and Chief Executive Officer of Prime Meridian Bank and Prime Meridian Holding Company, “Our year-to-date performance has been solid, particularly our growth in loans and mortgage banking revenue. The new office in Crawfordville, Florida has opened to a warm welcome and we are very optimistic about opportunities in that market. We continue to look for other attractive branching and expansionary prospects to expand our footprint.”

Earnings Summary

The Company reported net interest income of $2.2 million for the quarter ended September 30, 2015 compared to $1.9 million for the quarter ended September 30, 2014. The net interest margin for the quarter ended September 30, 2015 was 3.88%, compared to 3.79% for the 2014 third quarter. For the nine months ended September 30, 2015, net interest income totaled $6.3 million, compared to $5.4 million for the comparable period in 2014, and the net interest margin was 3.90% for the nine months ended September 30, 2015, compared to 3.54% a year ago. The increase in net interest income for both periods was driven by higher loan production, partially offset by slight decreases in income from securities and 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 September 30, 2015, the Company reported a $124,000 loan loss provision, compared to a $206,000 provision in the third quarter of 2014. For the nine months ended September 30, 2015, the Company recorded a $333,000 loan loss provision, compared to a $797,000 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 September 30, 2015 increased $83,000 from the same period a year ago and noninterest income for the nine months ended September 30, 2015 increased $215,000 over the comparable period in 2014. Growth in mortgage banking revenue predominantly drove the increases for the quarter and the nine-month period ended September 30, 2015.

Noninterest expense increased $287,000, or 19.6%, to $1.8 million for the three months ended September 30, 2015 compared to the same period a year ago. For the nine months ended September 30, 2015, noninterest expense totaled $4.8 million, a $379,000 increase over the comparable period in 2014. The rise in noninterest expense for both year-over-year periods is primarily attributed to higher salaries and employee benefits and occupancy and equipment expense as the Company expanded its employee base from forty-one full-time equivalent employees at September 30, 2014 to fifty-four full-time equivalent employees at September 30, 2015 and opened a new banking office.
