Founded in 1868 by T. C. Frost as an outgrowth of his mercantile business, Frost has grown into one of the country’s most respected financial institutions. As the banking subsidiary of Cullen/ Frost Bankers, Inc., a $31.2 billion (as of September 30, 2018) financial holding company headquartered in San Antonio, Frost is the largest Texas–based bank that operates only in Texas. It is also one of the 50 largest U.S. banks by asset size. The company’s financial strength is well documented. Frost was the only top-10 Texas-based bank to survive the economic downturn of the 1980s without federal assistance or a takeover by an out-of-state financial institution. And during the financial crisis and recession of 2008-2009, Frost turned down Troubled Asset Relief Program (TARP) funding, the first bank in the nation to publicly do so. In fact, Frost expanded its business throughout the recession, growing assets and deposits and increasing the dividend paid to shareholders. Today, Frost offers customers a broad range of financial services, including consumer and business banking, treasury management services, insurance products, investments, private trusts, retirement and financial management services, and investment banking services. The bank operates more than 130 financial centers across Texas in the Austin, Corpus Christi, Dallas, Fort Worth, Houston, Permian Basin, Rio Grande Valley and San Antonio regions. While mergers create vast coast-to-coast banking organizations, Frost continues to reinforce its core business strategy by building long-term relationships with its customers and strengthening its Texas roots. This strategy enables Frost to deliver the resources, products and technology of a larger bank with the friendly, personalized customer service of a smaller community bank.
