Catalyst Bancorp is the holding company for Catalyst Bank, a community bank headquartered in Opelousas, Louisiana, operating six branches across the Acadiana region of south-central Louisiana. Catalyst Bank operates on the traditional community banking model: it takes in deposits from local retail customers, small businesses, professionals, and municipal governments, then lends that money out at higher rates, with net interest income as the primary revenue driver. The bank's $170M loan portfolio was historically concentrated in single-family residential mortgages, which still represent the largest share of loans at just under half the portfolio. Since 2021, Catalyst Bank has been deliberately shifting toward a broader commercial banking model, growing commercial real estate and C&I loans to local businesses, targeting the oil and gas services, industrial equipment, and professional services sectors. This shift is driven by the higher yields and shorter maturities that commercial loans offer relative to the legacy residential book. The bank also holds an investment securities portfolio consisting mainly of agency mortgage-backed securities. Catalyst Bank funds itself primarily through local retail deposits, supplemented by FHLB advances and municipal deposits. Catalyst Bancorp converted from a mutual to a stock-holding company in 2021, giving it access to capital markets and the ability to pursue acquisitions, though no specific deal has been announced.
