First National Corporation Reports RECORD SECOND Quarter 2025 EARNINGS

STRASBURG, Va., July 30, 2025 --- First National Corporation (the “Company” or “First National”) (NASDAQ: FXNC), the bank holding company of First Bank (the “Bank”), reported earnings for the quarter ended June 30, 2025 of $5.05 million and basic and diluted earnings per common share of $0.56. Excluding acquisition-related items, adjusted earnings⁽¹⁾ (non-GAAP) for the second quarter of 2025 were $5.1 million and adjusted basic and diluted earnings⁽¹⁾ per common share were $0.57.

“We are extremely pleased with our performance in the second quarter as we begin to realize the value of our recently completed acquisition of the Touchstone franchise.  Earnings improved over the prior quarter and the previous year due to net interest margin expansion and our improved efficiency as a combined company.  While growth was muted due to higher than average loan payoff volumes and our focus on managing deposit pricing, this discipline delivered on improved earnings, strong liquidity and capital growth,” said Scott Harvard, President and Chief Executive Officer of First National. 

FINANCIAL HIGHLIGHTS FOR SECOND QUARTER 2025

NET INTEREST INCOME

For the second quarter of 2025, the Company’s net interest margin (FTE)⁽¹⁾ was 3.95%, up from 3.77% for the first quarter of 2025 and up from 3.40% in the second quarter of 2024. The Company’s net interest margin (FTE)⁽¹⁾ for the second quarter of 2025 includes the impact of acquisition accounting fair value adjustments. Net accretion income related to acquisition accounting was $907 thousand, or an 18-basis point incremental increase to the net interest margin for the second quarter ended June 30, 2025, compared to the net amortization expense of $36 thousand or a 1-basis point incremental decrease to the net interest margin for the first quarter ended March 31, 2025. The impact of accretion and amortization for the periods presented are reflected in the following table (dollars in thousands):

NONINTEREST INCOME

Non-interest income increased $278 thousand to $3.9 million for the second quarter of 2025 from $3.6 million in the prior quarter.  Non-interest income increased 7.7% in the second quarter primarily due to increases in ATM and check card income as well as brokered mortgage fees. 

NONINTEREST EXPENSE

Noninterest expense decreased $3.1 million to $15.2 million for the second quarter of 2025 from $18.3 million in the prior quarter, primarily driven by a $1.8 million decrease in pre-tax merger-related expenses, $656 thousand decrease in salaries and employee benefit expenses, $448 thousand decrease in other operating expenses, and $258 thousand decrease in data processes expense. The decrease in salaries and benefits reflects reduced expenses related to incentives, stock compensation expense, and other salary and benefits. The decrease in other operating expenses is driven by $294 thousand of fraud losses recognized in the first quarter and a reduction in internet banking expenses of $296 thousand. In the first quarter of 2025 the Bank was operating two core banking systems which added to our expense structure.  The conversion to one system occurred in February of 2025, which was a driver of reduced operating expenses in the second quarter of 2025.

Adjusted operating noninterest expense⁽¹⁾, which excludes merger-related costs ($92 thousand in the second quarter of  2025 and $1.9 million in the first quarter of 2025) and amortization of intangible assets ($441 thousand in the second quarter of 2025 and $442 thousand in the first quarter of 2025), decreased $1.3 million to $14.7 million for the second quarter of 2025 from $16.0 million in the prior quarter, due to decreases in salary and employee benefits expense, fraud losses, data processing, and internet banking expenses.

At June 30, 2025, total assets were $2.041 billion, an increase of $8.1 million or 0.4% from March 31, 2025, and an increase of $583.9 million or 40.1% from June 30, 2024. Total assets were consistent with the prior quarter and the increase from the prior year was primarily driven by growth in loans held for investment ("LHFI") (net of deferred fees and costs), primarily due to the Touchstone acquisition.

At June 30, 2025, total investments were $299.6 million, an increase of $25.9 million or 9.5% from March 31, 2025, and an increase of $29.2 million or 10.8% from June 30, 2024. Available for sale ("AFS") securities totaled $187.6 million at June 30, 2025, and $161.0 million at March 31, 2025, and $144.8 million at June 30, 2024. The increases compared to the prior quarter was driven by securities purchases and a $3.1 million improvement in unrealized losses. Total net unrealized losses on the AFS securities portfolio were $18.9 million at June 30, 2025, compared to $20.1 million at March 31, 2025, and $21.9 million at June 30, 2024. Held to maturity securities are carried at amortized cost and totaled $106.4 million at June 30, 2025, $108.3 million at March 31, 2025, and $123.5 million at June 30, 2024.

ASSET QUALITY

Nonperforming Assets

Management classifies non-performing assets ("NPAs") as non-accrual loans and other real estate owned ("OREO"). NPAs as a percentage of total assets increased to 0.33% on June 30, 2025, compared to 0.24% on March 31, 2025, and decreased from 0.59% on June 30, 2024.

NPAs increased by $1.9 million to $6.8 million on June 30, 2025, compared to $4.9 million on March 31, 2025, and $8.5 million on June 30, 2024. 

Allowance and Provision for Credit Losses

The allowance for credit losses on loans totaled $15.2 million, or 1.05% of total loans on June 30, 2025, compared to $14.7 million, or 1.02% of total loans on March 31, 2025, and $12.6 million, or 1.27% of total loans on June 30, 2024. The allowance for credit losses to NPAs decreased to 223.45% on June 30, 2025 compared to 302.94% on March 31, 2025, but increased from 146.84% on June 30, 2024. 

The Company recorded a $911 thousand provision for credit losses in the second quarter of 2025, compared to a $832 thousand provision for credit losses for the first quarter of 2025. The second quarter provision was comprised of a $900 thousand provision for credit losses on loans, a $1 thousand provision for credit losses on unfunded commitments and a $10 thousand provision for credit losses on held-to-maturity securities. The increase in provision for credit losses is primarily due to the calculated specific reserves on individually analyzed loans that were increased during the quarter in tandem with an increase in the total amount of loan balances individually analyzed for impairment.
