Landmark Bancorp is a bank holding company that operates Landmark Bank, attracting deposits from the general public and using those deposits along with other funding sources to originate loans across diverse categories including residential real estate, commercial real estate, business loans, agriculture, municipal, and consumer lending. The bank gathers deposits across all types—non-interest-bearing demand accounts, money market, checking, savings, and certificates of deposit—which form the primary funding source for its lending operations and generate net interest income. The company earns revenue primarily from the spread between interest earned on loans and interest paid on deposits, while managing interest rate risk through asset-liability management strategies, and returns capital to shareholders through quarterly cash dividends.
