First Horizon Corporation

First Horizon Corporation (NYSE: FHN), headquartered in Memphis, Tennessee, is a regional financial-services holding company operating across 12 southeastern U.S. states through its principal subsidiary, First Horizon Bank. The franchise reports roughly $84 billion in total assets, $67 billion in deposits, and approximately 410 banking centers as of Q1 2026. Business lines include consumer and small-business banking, commercial and specialty lending, private banking and wealth management, and FHN Financial fixed- income capital markets. The company was founded in 1864 as First National Bank of Memphis, rebranded as First Tennessee in 1977, became First Horizon National Corporation in 2004, and shortened its name to First Horizon Corporation following the 2020 IberiaBank merger. In February 2022 First Horizon announced a $13.4 billion all-cash acquisition by Toronto-Dominion Bank; the parties mutually terminated the merger on May 4, 2023, citing regulatory uncertainty around the deal's closing timeline, with TD paying a $225 million termination fee plus a previously agreed $25 million reimbursement to First Horizon. First Horizon does not publish a public developer API portal. Customer account data is reachable for fintech use cases only through US open-banking aggregators (Plaid, MX, Finicity, Akoya) and through emerging Financial Data Exchange (FDX) APIs that will be required of covered data providers under the CFPB Section 1033 Personal Financial Data Rights rule. Commercial APIs for treasury management, ACH origination, wire initiation, and host-to-host file transfer are available to corporate clients under direct contract through First Horizon Treasury Management Services but are not publicly documented.
