BOK Financial Corporation (BOKF) Stock Analysis & Winston Score
BOK Financial Corporation is a regional bank headquartered in Tulsa, Oklahoma. It offers everyday banking services like checking accounts, loans, and mortgages, as well as wealth management, investment services, and energy lending. The company serves individuals, businesses, and institutions primarily across the south-central United States, including Oklahoma, Texas, Colorado, Arizona, and several neighboring states. BOK Financial makes money through interest income on loans and deposits, plus fees from services like brokerage, trust management, and mortgage banking. It operates roughly 100 branches and manages around $50 billion in assets, making it one of the larger regional banks in its region. The company has a notable concentration in energy-sector lending, which gives it specialized expertise but also ties its loan portfolio closely to oil and gas prices — meaning a prolonged downturn in energy markets remains one of its most significant risks.
