Arvest Bank has a long-standing history of strategic growth through targeted community bank acquisitions across Arkansas, Oklahoma, Missouri, and Kansas. Over decades of expansion, Arvest has acquired numerous institutions, beginning historically with the Bank of Bentonville, McIlroy Bank & Trust in Fayetteville, Central Bank and Trust in Little Rock, and WestStar Bank in Oklahoma. One of its most substantial modern acquisitions was Bear State Bank, which significantly expanded Arvest's operating footprint into new communities across northeast and southwest Arkansas, southern Missouri, and southeast Oklahoma, adding dozens of new banking locations to its regional network.
