STRASBURG, Va., April  30, 2025  (GLOBE NEWSWIRE) -- First National Corporation (the “Company” or “First National”) (NASDAQ: FXNC), the bank holding company of First Bank (the “Bank”), reported earnings for the quarter ending March 31, 2025 of $1.52 million and basic and diluted earnings per common share of $0.18. Excluding acquisition-related items adjusted earnings(1) (non-GAAP) for the first quarter of 2025 were $3.1 million and adjusted basic and diluted earnings(1) per common share was $0.35.

“We completed the Touchstone system conversion during the first quarter of 2025 and are looking forward to building upon this transformational acquisition.  Earnings were impacted short-term in the first quarter from merger related expenses as well as operating on two different systems until late February.  Going forward we expect to return to our efficient model of banking and enjoy scale and growth from these new markets,” said Scott Harvard, President and Chief Executive Officer of First National.

FIRST QUARTER 2025 HIGHLIGHTS

MERGER WITH TOUCHSTONE BANKSHARES, INC. (“TOUCHSTONE”)

On October 1, 2024, the Company completed its acquisition of Touchstone. Touchstone’s results of operations are included in the Company’s consolidated results since the date of acquisition, and, therefore, the Company’s first quarter 2025 and fourth quarter 2024 results reflect significantly increased levels of average balances, net interest income, direct merger expenses and operational expenses compared to the first quarter 2024. The Company incurred pre-tax merger costs of approximately $1.9 million during the first quarter of 2025 related to the Touchstone acquisition as well as duplicative operating costs until the operational merger was completed in the first quarter.  Duplicative operating costs are not included in merger expenses.

NET INTEREST INCOME

For the first quarter of 2025, the Company’s net interest margin fully taxable equivalent ("FTE")(1) was 3.77%, down from 3.83% for the fourth quarter of 2024 but up from 3.24% in the first quarter of 2024. The Company’s net interest margin (FTE)(1) for the first quarter of 2025 includes the impact of acquisition accounting fair value adjustments. Net amortization expense related to acquisition accounting was $36 thousand, or a one basis point incremental decrease to the net interest margin for the first quarter ended March 31, 2025, compared to the net accretion income of $1.1 million or a 22-basis point incremental increase to the net interest margin for the fourth quarter ended December 31, 2024. The impact of accretion and amortization for the periods presented are reflected in the following table (dollars in thousands):

Earning asset yields for the first quarter of 2025 decreased 12 basis points to 5.18% compared to the fourth quarter of 2024, and the cost of funds decreased by 6 basis points to 1.45%, due to changes in deposit mix following the acquisition of Touchstone and federal funds rate cuts in late 2024.  For the first quarter of 2025, net interest income was $17.5 million, a decrease of $908 thousand from $18.4 million in the fourth quarter of 2024 due to the impact of amortization on early payoffs of Touchstone loans which also reduced interest earning assets, partially offset by a $28.9 million decrease in average interest-bearing liabilities.

NONINTEREST INCOME

Non-interest income decreased $2.8 million to $3.6 million for the first quarter of 2025 from $6.4 million in the prior quarter.  Excluding the $2.9 million one-time bargain purchase gain associated with the Touchstone acquisition in the fourth quarter of 2024, non-interest income increased 2.5% in the first quarter despite one-time waived customer service charges on acquired deposits to facilitate the Touchstone systems conversion. Service charges on deposits and customer service fees decreased from the prior quarter but were offset by increases in ATM and check card income during the first quarter.

NONINTEREST EXPENSE

Noninterest expense decreased $3.6 million to $18.3 million for the first quarter of 2025 from $21.9 million in the prior quarter, primarily driven by a $5.4 million decrease in pre-tax merger-related expenses offset by a $1.2 million increase in salaries and benefit expenses, fraud losses of $294 thousand, and increases in our FDIC insurance assessment. The increase in salaries and benefits reflects additional expenses related to incentives, stock compensation expense, and salary and benefit increases from the prior quarter.

Adjusted operating noninterest expense(1), which excludes merger-related costs ($1.9 million in the first quarter of  2025 and $7.3 million in the fourth quarter of 2024) and amortization of intangible assets ($442 thousand in the first quarter of  2025 and $448 thousand in the fourth quarter of 2024), increased $1.8 million to $16.0 million for the first quarter of 2025 from $14.2 million in the prior quarter, due to the increase in salary and employee benefits expense, fraud losses, and increases in our FDIC insurance assessment.

BALANCE SHEET

At March 31, 2025, total assets were $2.033 billion, an increase of $23.1 million or 1.1% from December 31, 2024, and an increase of $586.2 million or 40.5% from March 31, 2024. The increase in total assets from the prior quarter was primarily due to an increase in cash and cash equivalents and the increase from 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 March 31, 2025, LHFI net of allowance totaled $1.436 billion, a decrease of $14.7 million from $1.451 billion or 1.0% at December 31, 2024, and an increase of $475.5 million or 49.5% from March 31, 2024. LHFI was consistent with the prior quarter and increased from the prior year primarily due to the Touchstone acquisition, as well as organic loan growth.

At March 31, 2025, total investments were $273.7 million, a decrease of $3.6 million or 1.3% from December 31, 2024, and a decrease of $1.9 million or 0.7% from March 31, 2024. Available for sale (AFS) securities totaled $161.0 million at March 31, 2025, and $163.8 million at December 31, 2024, and $147.7 million at March 31, 2024. The decreases compared to the prior quarter was driven by the $2.0 million improvement in unrealized losses. Total net unrealized losses on the AFS securities portfolio were $20.1 million at March 31, 2025, compared to $22.1 million at December 31, 2024, and $22.2 million at March 31, 2024. Held to maturity securities are carried at cost and totaled $108.3 million at March 31, 2025, $109.7 million at December 31, 2024, and $125.8 million at March 31, 2024.

At March 31, 2025, total deposits were $1.825 billion, an increase of $21.2 million or 1.2% from the prior quarter, and an increase of $565.8 million or 44.9% from March 31, 2024. The increases in deposit balances from the prior quarter and prior year are primarily due to increases in noninterest bearing deposits and the addition of the Touchstone acquired deposits.

There were no other borrowings on March 31, 2025, or December 31, 2024. Other borrowings totaled $50.0 million on March 31, 2024, and were comprised of funds borrowed from the Federal Reserve Bank through their Bank Term Funding Program which were repaid during the fourth quarter of 2024.

LIQUIDITY

Liquidity sources available to the Bank, including interest-bearing deposits in banks, unpledged securities available for sale, at fair value, unpledged securities held-to-maturity, at par, eligible to be pledged, and available lines of credit totaled $800.2 million on March 31, 2025, $770.0 million on December 31, 2024, and $554.8 million on March 31, 2024.

The Bank maintains liquidity to fund loan growth and to meet potential demand from deposit customers, including potential volatile deposits. The estimated amount of uninsured customer deposits totaled $549.3 million on March 31, 2025, $537.0 million on December 31, 2024, and $391.9 million on March 31, 2024. Excluding municipal deposits, the estimated amount of uninsured customer deposits totaled $458.7 million on March 31, 2025, $445.5 million on December 31, 2024, and $308.6 million on March 31, 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 decreased to 0.24% on March 31, 2025, compared to 0.35% on December 31, 2024, and 0.55% on March 31, 2024. The allowance for credit losses to NPAs increased to 302.94% on March 31, 2025, compared to 233.49% on December 31, 2024, and 157.24% on March 31, 2024.

NPAs decreased by $2.2 million to $4.9 million on March 31, 2025, compared to $7.0 million on December 31, 2024, and $8.0 million on March 31, 2024. The decrease in NPAs during the first quarter of 2025 resulted from the charge-off of previously individually evaluated commercial and industrial loans.

Past Due Loans

There were no loans past due over 90 days or more and still accruing interest on March 31, 2025, compared to $365 thousand on December 31, 2024, and $175 thousand on March 31, 2024. Loans past-due 30-89 days and still accruing interest increased to $5.0 million, or 0.35% of total loans on March 31, 2025, compared to $3.1 million, or 0.21% of total loans on December 31, 2024, and $2.3 million, or 0.23%, of total loans on March 31, 2024.

Net Charge-offs

For the first quarter of 2025 net charge-offs included $2.2 million of commercial and industrial loans, with $208 thousand of that specific to our pool of loans originated to health care professionals through a third-party lender. Net charge-offs totaled $2.4 million in the first quarter of 2025, compared to $1.3 million in the fourth quarter of 2024, and $362 thousand in the first quarter of 2024.

Allowance for Credit Losses

The allowance for credit losses on loans totaled $14.7 million, or 1.02% of total loans on March 31, 2025, compared to $16.4 million, or 1.12% of total loans on December 31, 2024, and $12.6 million, or 1.30% of total loans on March 31, 2024.  The Company recorded a $832 thousand provision for credit losses in the first quarter of 2025, compared to a $4.8 million provision for credit losses for the fourth quarter of 2024. The first quarter provision was comprised of a $735 thousand provision for credit losses on loans, a $104 thousand provision for credit losses on unfunded commitments and a $7 thousand recovery of credit losses on held-to-maturity securities.

The calculated specific reserve decreased after previously identified individually evaluated loans were charged off during the quarter.  The provision for credit losses for the fourth quarter of 2024 included a $3.8 million initial provision expense on non-PCD loans and $100 thousand on unfunded commitments, as a result of the Touchstone acquisition. As compared to the prior quarter and same period prior year, the decrease in provision for credit losses, outside of the initial provision expense recorded on non-PCD loans and unfunded commitments acquired from Touchstone, primarily reflects the impact of charge-offs of previously identified specific reserves, lower pool loan balances partially offset by a minor increase in the pooled loans quantitative reserve ratio, and changes in qualitative factor adjustments related to the commercial and industrial loan pool. The overall allowance decreased from the impact of lower pooled loan balances, and the specific reserve decreased following the charge-off of previously identified specific reserves during the quarter.

CAPITAL

During the first quarter of 2025, the Company declared and paid cash dividends of $0.155 per common share, compared to $0.155 in the fourth quarter of 2024 and $0.15 in the first quarter of 2024.
