First National Corporation is a Virginia-chartered bank holding company that operates through its primary subsidiary, First Bank. First Bank offers standard community banking products: consumer, residential mortgage, home equity, and commercial loans; deposit accounts including checking, savings, money market, CDs, and IRAs; and wealth management services covering estate planning, investment management, and trust services. First Bank serves individuals, small and medium-sized businesses, non-profits, and local government entities across 33 branch offices in Virginia's Shenandoah Valley, Roanoke Valley, and south-central Virginia, including the Richmond metro area and northern North Carolina. First Bank's primary revenue is net interest income — the spread between interest earned on loans and investments and interest paid on deposits — which is driven by the size of the loan and investment portfolio, rates earned versus rates paid, and the mix of floating- versus fixed-rate assets. First Bank also earns noninterest income through service charges, wealth management fees, and ATM and debit card fees. Salaries and benefits represent roughly half of noninterest expenses. As a community bank, First Bank's profitability is closely tied to the health of its local Virginia and North Carolina markets.
