PRIME MERIDIAN HOLDING COMPANY REPORTS

FIRST QUARTER RESULTS

TALLAHASSEE, FL., May 11, 2015 (GLOBE NEWSWIRE) – Prime Meridian Holding Company (the “Company”), the parent bank holding company for Prime Meridian Bank (the “Bank”), today announced financial results for the quarter ended March 31, 2015. The Company reported net earnings of $449,000, or $0.23 per basic and diluted share for the quarter ended March 31, 2015, compared to net earnings of $256,000, or $0.17 per basic and diluted share for the quarter ended March 31, 2014.

Highlights

Market Conditions

“Home buying (and building) continue their upward trend,” said Prime Meridian Bank CEO and President, Sammie D. Dixon. “We saw opportunities early on to bring aboard some of the best mortgage loan originators. We did so and are very pleased with the results.”

Likewise the Bank continues to reinforce relationships with key players in the mortgage arena. “Fostering these relationships when the market was down has helped our growth today,” Dixon said.

“Prime Meridian Bank is not just talking about growth,” he added. “We are making growth happen.” Application for expansion into neighboring Wakulla County is pending regulatory approval.

According to Dixon, the Bank anticipates this move will yield significant deposit relationships as well as lending opportunities. The Bank has already added an experienced market president and assistant manager.

“We continue to position ourselves to take advantage of opportunities as they emerge,” Dixon said.

Net Interest Income

The Company reported net interest income of $2.0 million for the quarter ended March 31, 2015 compared to $1.7 million for the same period a year ago. The $299,000, or 17.4% increase, was driven by higher loan balances and modest gains in interest income from securities, partially offset by an $18,000 decrease in other interest income. A $4,000, or 2.3%, decrease in interest expense also contributed to the higher net interest income.

The Company reported total net loans of $153.6 million at March 31, 2015 compared to $151.9 million at December 31, 2014 and $125.2 million at March 31, 2014. Despite a continued low rate environment, the higher average loan balances in the first quarter of 2015 boosted interest income. The slight decrease in interest expense can also be attributed to the low rate environment, but this effect was mostly offset by a shift in our deposit mix towards a higher percentage of interest-bearing deposits. The shift in our deposit mix resulted from the declining balance of one noninterest-bearing deposit account over the course of 2014.

The net interest margin was 3.89% for the quarter ended March 31, 2015, up from 3.36% for the quarter ended March 31, 2014, as a 54 basis points increase in the average yield on total interest-earning assets was complemented by a 5 basis points decrease in the average rate paid on total interest-bearing liabilities. Although there continues to be downward pricing pressure on loans, higher average loan balances as a percentage of total interest earning assets helped improve the overall yield on interest earning assets.

Noninterest Income

For the quarter ended March 31, 2015, noninterest income increased $60,000 from the same period a year ago, due to a $22,000 increase in mortgage banking revenue and a $42,000 gain on sale of securities available for sale. The growth in mortgage banking revenue primarily reflects increased activity in new home purchases. These gains were partially offset by small decreases in service charges and fees on deposit accounts and income from bank-owned life insurance.

Noninterest Expense

Noninterest expense increased $64,000, or 4.5%, to $1.5 million for the three months ended March 31, 2015 compared to the same period a year ago. The increase was primarily due to a $53,000 increase in occupancy and equipment expense and a $35,000 increase in marketing. Higher occupancy and equipment expense is primarily attributed to additional leased space at our Timberlane location, while the increase in marketing can be attributed to higher levels of spending on sponsorships, business development and advertising. Salaries and employee benefits show a $4,000 decrease from the three months ended March 31, 2014 to the three months ended March 31, 2015, despite growth in the number of full-time equivalent employees from 41 to 47. The decrease is explained by a change in our estimated standard deferred loan costs related to loan originations and renewals which are netted against salaries and then amortized as an offset to loan fees over the life of the loan to which they apply. The Bank’s new

estimates more specifically allocate loan costs according to loan type. This resulted in a $141,000 increase in deferred loan costs for the period ended March 31, 2015 compared to the same period a year ago, which offset a $133,000 increase in salaries and employee benefits for the same time periods.

Financial Condition

Balance Sheet

As of March 31, 2015

(in thousands)

As of March 31, 2015, the Company had grown to $220.5 million in total assets, $192.8 million in deposits, and $153.6 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.

The composition of the Bank’s loan portfolio consisted of the following at March 31, 2015 and December 31, 2014 (in thousands):

Loans totaling $230,000 were deemed to be impaired under the Bank’s policy at March 31, 2015, while loans totaling $237,000 were deemed to be impaired under the Bank’s policy at December 31, 2014. At March 31, 2015, we had three non-accruing loans in the aggregate amount of $176,000, compared to two non-accruing loans at December 31, 2014, totaling $171,000. There were no net charge-offs or recoveries for the quarter ended March 31, 2015.

The provision for loan losses for the quarter ended March 31, 2015 and 2014 was $18,000 and $29,000, respectively. The decrease in the provision quarter over quarter can be attributed to slower net loan growth in the first quarter of 2015. Management believes that the allowance for loan and losses (“ALLL”), which was $2.1 million, or 1.36% of gross loans, at March 31, 2015 is adequate.

Total stockholder’s equity was $23.6 million as of March 31, 2015, compared to $22.9 million as of December 31, 2014. Book value per share was $12.12 as of March 31, 2015, with 1,943,534 common shares outstanding. Equity capital increased from December 31, 2014 due mostly to earnings retention and a positive net change in the unrealized gain on securities available for sale. As of March 31, 2015, the Bank was considered to be “well capitalized” with a 10.29% Tier 1 leverage Capital ratio, a 13.83% Common Equity Tier 1 Risk-Based Capital Ratio, a 13.83% Tier 1 Risk-Based Capital Ratio, and a 15.08% Total Risk-Based Capital Ratio, all above the minimum ratios to be considered “well capitalized.”
