• McKenney Group, LLC: This subsidiary owns an interest in a now inactive entity that previously provided insurance services. Although the underlying entity is inactive, the LLC remains as a holding structure. It does not currently contribute to revenue or operations.

• First National (VA) Statutory Trust II and First National (VA) Statutory Trust III (collectively, the Trusts): These trusts were formed for the purpose of issuing redeemable capital securities, commonly known as trust preferred securities.

The Trusts do not engage in operational activities but serve a financing function.

First National Corporation operates in a highly competitive financial services industry, facing competition from large national and regional banks, credit unions, community banks, consumer finance companies, mortgage companies, marketplace lenders, financial technology firms, mutual funds, and life insurance companies. The Bank's competitive advantages include long-term customer relationships, a commitment to excellent customer service, dedicated and loyal employees, and active involvement in the communities it serves. These strengths help the Bank maintain its market position despite industry pressures.

First National Corporation serves individuals, small and medium-sized businesses, non-profit organizations, and local governmental entities within its market area. The Bank's customers are located along the Interstate 81, Interstate 66, and Interstate 64 corridors in the Shenandoah Valley, the Roanoke Valley, and the south-central region of Virginia, including the Richmond MSA and northern North Carolina. The Bank does not rely on any single or few customers, as the loss of any one customer would not have a material adverse effect on its business.
