Business Description

Overview We are a Pennsylvania corporation, a bank holding company and a financial holding company. We are incorporated under the laws of the Commonwealth of Pennsylvania, and through our subsidiaries, we have been in business since 1864. Our headquarters is located at 626 Washington Place, Pittsburgh, Pennsylvania 15219. As a diversified financial services holding company, FNB, through our subsidiaries, provides a full range of financial services, principally to consumers, corporations, governments and small- to medium-sized businesses in our market areas through our subsidiary network, which is led by our largest subsidiary, FNBPA. Our business strategy focuses primarily on providing quality, consumer- and commercial-based financial services adapted to the needs of each of the markets we serve. We seek to maintain our community orientation by providing local management with certain autonomy in decision making, enabling them to respond to customer requests more quickly and to concentrate on efficiently delivering products and services within their market areas. However, we have centralized operations, support and risk functions (e.g., loan operations, treasury and enterprise risk management). The centralization of these processes enables us to maintain consistent quality of these functions and to achieve certain economies of scale. As of December 31, 2025, we have three reportable business segments: Community Banking, Wealth Management and Insurance. Our remaining operations are described in Other . As of December 31, 2025, we have 355 Community Banking branches in Pennsylvania, Ohio, Maryland, West Virginia, North Carolina, South Carolina, Washington, D.C. and Virginia. As of December 31, 2025, we had total assets of $50 billion, loans of $35 billion and deposits of $39 billion.
