Business Description

Investar Holding Corporation, a Louisiana corporation incorporated in 2009, is a financial holding company headquartered in Baton Rouge, Louisiana that conducts its operations primarily through its wholly-owned subsidiary, Investar Bank, National Association, a national bank chartered by the OCC. The Bank was originally chartered as a Louisiana commercial bank in 2006 and converted to a national bank in July 2019. Through the Bank, the Company offers a wide range of commercial banking products tailored to meet the needs of individuals, professionals, and small to medium-sized businesses. Our primary areas of operation are south Louisiana, including Baton Rouge, New Orleans, Lafayette, Lake Charles, and their surrounding areas; Texas, including Houston and its surrounding area, and, as of January 1, 2026, north Dallas and Wichita Falls and their surrounding areas; and Alabama, including York and Oxford and their surrounding areas. These markets are served from our executive and operations center located in Baton Rouge an d from 36 full-serv ice branches located throughout our market areas. We have experienced significant growth since the Bank was chartered, completing eight whole-bank acquisitions and establishing additional branches in our market areas. As of December 31, 2025, on a consolidated basis, the Company had total assets of $2.8 billion, net loans of $2.1 billion, total deposits of $2.4 billion, and stockholders’ equity of $301.1 million. Our strategy focuses on consistent, quality earnings through the optimization of our balance sheet by originating and renewing high quality, primarily variable-rate, loans and allowing higher risk credit relationships to run off. Our strategy also includes growth through acquisitions, including whole-bank acquisitions, strategic branch acquisitions and asset acquisitions. Over time, management believes that we have significant opportunities for growth and franchise expansion, both organically and through strategic acquisitions. Although the financial services industry is rapidly changing and intensely competitive, and likely to remain so, we believe that the Bank competes effectively as a local community bank and possesses the availability of local access and responsive customer service, coupled with competitively-priced products and services, necessary to successfully compete with other financial institutions for individual and small to medium-sized business customers.
