The First of Long Island Corporation is the holding company for The First National Bank of Long Island, a community bank founded in 1927 that serves Nassau and Suffolk Counties and the New York City boroughs through a network of 37 branches. The Bank's core customers are small to mid-sized businesses, professional service firms, not-for-profits, municipalities, and consumers, with a focus on long-term relationship banking rather than transactional business. The Bank earns revenue primarily through net interest income — the spread between interest earned on loans and investment securities and interest paid on deposits and borrowings — with a secondary, more stable stream from non-interest income including service charges, bank-owned life insurance, and merchant card services. The loan book is concentrated in commercial real estate, particularly multifamily, though management is actively remixing toward C&I and owner-occupied commercial mortgages, which have grown from roughly 7% to 12% of loans since 2020. Residential mortgage originations have been halted entirely, with that portfolio being run off. The Bank has also been rationalizing its branch network, consolidating from 52 to 37 branches since 2019 while growing deposits. A pending all-stock merger with ConnectOne Bancorp, announced in September 2024 and approved by shareholders in February 2025, is expected to close in Q2 2025, with ConnectOne as the surviving entity.
