SB Financial is a small community bank holding company based in Defiance, Ohio. Its core business is commercial banking through its subsidiary, The State Bank and Trust Company, which operates 27 branches and four loan production offices across Northwest Ohio, the Columbus metro area, and Northeast Indiana. The loan portfolio is the primary earnings driver, weighted toward commercial real estate but also including C&I, consumer, agricultural, and residential mortgage loans. Beyond traditional lending, SB Financial generates fee income through three supplementary businesses: mortgage banking (originating and selling residential loans into the secondary market), wealth management (trust, asset management, and brokerage services with roughly $566M in assets under care), and title insurance through its subsidiary Peak Title Agency. Net interest income drives roughly 74% of total revenue, with the remainder coming from these fee-based businesses. SB Financial funds its loan book primarily through a stable, low-cost core deposit base, earning a net interest margin of roughly 3.51%. Growth strategy centers on geographic expansion — particularly in the Columbus metro, Fort Wayne, Indiana, and de novo offices in smaller Ohio and Indiana markets — while also targeting customers disrupted by regional bank consolidation. SB Financial completed the acquisition of Marblehead Bank in early 2025, adding roughly $56M in low-cost deposits. Management's stated goal is to maintain a more balanced mix between interest and fee income over time, and to grow the agricultural lending portfolio and expand cross-selling across its roughly 39,000 households.
