PRIME MERIDIAN HOLDING COMPANY REPORTS

FIRST QUARTER 2018 RESULTS

TALLAHASSEE, FL., April 24, 2018 (GLOBE NEWSWIRE) – Prime Meridian Holding Company (OTCQX: PMHG) the parent bank holding company for Prime Meridian Bank today announced unaudited financial results for the quarter ended March 31, 2018. The Company reported net earnings of $754,000, or $0.24 per basic and diluted share, for the quarter ended March 31, 2018, compared to net earnings of $536,000 or $0.27 per basic and diluted share, for the quarter ended March 31, 2017.

“We are very pleased with our performance this quarter,” said Sammie D. Dixon, Jr., Vice Chairman, President and CEO of the Company. “We continued our growth in our loan portfolio and have kept our momentum going,” he continued, noting that booking loans early in the year elevates interest income for the year.

“There have been challenges, though,” Dixon reminded. “The market is experiencing a rising rate environment.” According to Dixon, “this has benefitted the Bank so far and means a new level of rate management both on the lending and depository side.”

“Maintaining good margins and levels of core deposits has meant adapting and responding to the market,” said Dixon. “We have done so through careful analysis, planning and often one-on-one communication with clients. We use the same approach when looking at growth opportunities. Our team models market information against our culture looking for a good fit,” explained Dixon. “We are planning and waiting for when we think the time is right.”

In February, the Bank’s mortgage department was the top producer both in terms of money volume and number of mortgages in Leon county, according to reporting by Metro Market Trends.

“I cannot say enough about our mortgage team,” said Dixon. “Home lending is a very competitive space — one that requires discipline and strong core values. We have remained conservative relative to rates, even as many competitors have become more aggressive. Our mortgage team represents us well and it shows.”

The Bank celebrated its 10th anniversary on February 4, 2018. “Ten years serving our clients and community is certainly a milestone,” said Dixon. “We appreciate the opportunity to be part of our clients’ successes.”

During a week-long 10-year anniversary celebration, many long-time clients shared their experiences with the Bank in social media videos. “Listening to what’s important to our clients is inspiring,” said Dixon. “It reinforces our core belief that good banking is just people helping people.”

An expression of that inspiration is the unprecedented level in which the Bank is giving back to the community. In addition to many annual sponsorships to local charities, the Bank was a first time Title Sponsor for Night to Shine, the Tim Tebow Foundation’s prom night experience for people with special needs. “The event had record attendance locally. We were grateful to play a role in its success,” said Dixon.

First Quarter 2018 Highlights compared with 2017

Earnings Summary

Net earnings for the three-month period ended March 31, 2018 were $754,000, compared to net earnings of $694,000 and $536,000 for the three-month periods ended December 31, 2017 and March 31, 2017, respectively. On a linked quarter basis, the $60,000 increase of net income is mostly due to a lower corporate income tax rate as earnings before income taxes were $998,000 for the first quarter of 2018, $246,000 lower than the $1.2 million reported for the fourth quarter of 2017. A 4.7%, or $163,000, increase in total interest income, a 4.0%, or $20,000, increase in total noninterest income, and a 55.6%, or $306,000, decrease in income tax expense were offset by a 12.8%, or $45,000, increase in interest expense, an 8.6%, or $199,000, increase in noninterest expense, and most significantly by a 268.1%, or $185,000, increase in the provision for loan losses, due to increased loan production.

The $218,000 increase in net earnings for the first three months of 2018 compared to the same period a year ago is attributed to a 24.8%, or $723,000, increase in total interest income, a 22.2%, or $94,000, increase in total noninterest income, and a 21.0%, or $65,000, decrease in income tax expense, all partially offset by a 60.7%, or $150,000, increase in total interest expense, a 625.7%, or $219,000, increase in the provision for loan losses, and a 13.4%, or $295,000, increase in total noninterest expense. There were two macro factors impacting results favorably in the first quarter of 2018 - the enactment of the Tax Cuts and Job Act on December 22, 2017 which has resulted in a lower corporate income tax rate and continued rising interest rates as the overnight funds rate increased in March, 2018 for the sixth time since December, 2015. The Bank’s strong first quarter loan production at higher yields than prior quarters outweighed its increased cost of funds.

Net Interest Income

Compared to the fourth quarter of 2017, net interest income increased $118,000, or 3.8%. Average earning assets increased $1.1 million, or 0.3%, on a linked quarter basis, while the net interest margin increased 13 basis points. Average earning asset growth included a $14.6 million, or 5.8%, increase in average loans, and a $209,000, or 0.4%, increase in average securities, partially offset by a $719,000 or 12.1%, decrease in average mortgage loans held for sale and a $13.0 million, or 42.8%, decrease in other interest-earning assets. The decrease in other interest-earning assets reflects a shift in our earning assets mix from overnight funds to higher yielding loans, which boosted first quarter profitability. The increase in the net interest margin reflected an 18 basis point increase in the yield on average interest-earning assets, partially offset by a 7 basis point increase in the cost of interest-bearing deposits. Noninterest-bearing deposits remained relatively unchanged from the prior quarter.

Net interest income for the 2018 first quarter increased $573,000, or 21.5%, from the 2017 first quarter. This reflected the benefit from the $42.5 million increase in average earning assets coupled with a 23 basis point improvement in the net interest margin to 3.83%. Average earning asset growth included a $39.1 million, or 17.2%, increase in average loans, a $3.0 million, or 131.5%, increase in average mortgage loans held for sale, and a $13.3 million, or 36.9%, increase in average securities, partially offset by a $13.0 million, or 42.7%, decrease in other interest-earning assets. Again, the shift in the earning assets mix from lower yielding overnight funds to higher yielding loans improved profitability for the first quarter of 2018. The net interest margin expansion reflected a 36 basis point increase in the average yield on earnings assets, partially offset by a 23 basis point increase in the average cost of interest-bearing deposits.

Provision for Loan Losses

The provision for loan losses was $254,000 for the quarter ended March 31, 2018, representing a $185,000, or 268.1%, increase over the quarter ended December 31, 2017 and a $219,000, or 625.7%, increase year over year. Net loans have increased $22.4 million from December 31, 2017 and $46.9 million since March 31, 2017, resulting in the higher provision.

Noninterest Income

Noninterest income increased $20,000, or 4.0%, from the fourth quarter of 2017. A $6,000, or 7.4%, increase in service charges and fees on deposit accounts, a $5,000, or 1.6%, increase in mortgage banking revenue, and a $9,000, or 9.7%, increase in other noninterest income (namely debit card and credit card fee income) all contributed to the increase over the prior quarter.

For the quarter ended March 31, 2018, noninterest income increased $94,000, or 22.2%, from the same period a year ago. The primary drivers of this increase were mortgage banking revenue which increased $66,000, or 26.3%, and higher other noninterest income which increased $21,000, or 25.9%, due mostly again to higher debit card and credit card fee income.

Noninterest Expense

For the quarter ended March 31, 2018, noninterest expense increased 8.6%, or $199,000, compared to the quarter ended December 31, 2017. The majority of the increase can be attributed to higher salaries and employee benefits. Also, marketing costs increased $73,000, or 54.5%, from the prior quarter as the Bank made a deliberate decision to elevate its marketing activities in 2018 and also forecasts approximately 35% of its marketing budget in the first quarter versus 16% in the fourth quarter. Slight increases in occupancy and equipment, professional fees, and software maintenance, amortization and other, also contributed to the increase in noninterest expense over the prior quarter.

Compared to the first quarter of 2017, noninterest expense increased $295,000, or 13.4%. Again, the majority of the increase is attributed to higher salaries and employee benefits as the Bank continues to add additional personnel as it positions itself for organic growth and possible expansionary activities. Full-time equivalent employees increased from 67 at March 31, 2017 to 71 at March 31, 2018, while salaries and employee benefits increased $188,000, or 15.1%. The other primary contributor to the increase in noninterest expense was marketing expense. The $53,000, or 34.4%, increase in marketing reflects a growing community bank’s expanding civic involvement.

Balance Sheet

As of March 31, 2018, the Company had grown to $358.3 million in total assets, $309.3 million in deposits, and $272.6 million in portfolio net loans. This compares to $347.2 million in total assets, $298.3 million in deposits, and $250.3 million in portfolio net loans as of December 31, 2017. The composition of the Bank’s loan portfolio was as follows on the indicated dates:

Loans by Class

(Dollars in thousands)

Total stockholders’ equity was $46.9 million, or 13.1% of total assets at March 31, 2018, compared to $47.0 million, or 13.5% of total assets, at December 31, 2017. Book value per share decreased slightly from $15.06 at December 31, 2017 to $15.03 at March 31, 2018, with 3,122,769 common shares outstanding. The slight decrease in book value was caused by an increase in the Company’s accumulated other comprehensive loss from $296,000 at December 31, 2017 to $841,000 at March 31, 2018 and a 3,792 increase in the number of shares outstanding.

As of March 31, 2018, the Bank was considered to be “well capitalized” with a Tier 1 Leverage Capital Ratio of 9.69%, a 12.38% Common Equity Tier 1 Risk-Based Capital Ratio, a 12.38% Tier 1 Risk-Based Capital Ratio, and a 13.61% Total Risk-Based Capital Ratio.

Asset Quality

Loans totaling $980,000 were deemed to be impaired under the Bank’s policy at March 31, 2018, while loans totaling $134,000 were deemed to be impaired under the Bank’s policy at December 31, 2017. At March 31, 2018, the Bank had three nonaccrual loans in the aggregate amount of $369,000 compared to two nonaccrual loans totaling $134,000 at December 31, 2017. Net charge-offs totaled $5,000 for the quarter ended March 31, 2018. Management believes that the allowance for loan losses which was $3.4 million, or 1.23% of gross loans, at March 31, 2018 is adequate.
