Amerant Bank

Overview

Amerant Bank, N.A. is a Coral Gables, Florida community bank and the main subsidiary of Amerant Bancorp Inc. (NYSE: AMTB), offering deposit, credit, and wealth-management services across South Florida and Tampa after selling its Houston franchise in 2024 (U.S. Securities and Exchange Commission). It traces its charter to 1979 and took the Amerant name in 2018 after spinning off from Venezuela’s Mercantil Servicios Financieros (Amerant).

This profile covers the bank, not the parent: Amerant Bancorp is the holding company whose stock trades as AMTB, while Amerant Bank, N.A. is the operating bank underneath it (Amerant). The bank describes itself as the largest community bank headquartered in Florida — its own characterization, not an independently verified ranking.

From Commercebank to independent Amerant

The bank was originally chartered as Gold Coast National Bank, later becoming Commercebank, N.A., founded in North Miami Beach, Florida, in 1979 (Amerant). With $53 million in assets and a second location in Coral Gables, Commercebank was acquired by Mercantil Servicios Financieros (MSF) in December 1987, beginning three decades as part of a Venezuelan-owned group (Amerant). The company moved its headquarters to Coral Gables in 1997, changed its name to Mercantil Commercebank in 2007, and then to Mercantil Bank, N.A. in 2017, by which point it held over $8 billion in assets (Amerant).

Independence came in 2018. The spin-off from MSF was announced on December 15, 2017, and completed on August 10, 2018, when the company finished its first quarter as a separate publicly-owned company (Amerant; Amerant). On October 24, 2018, the company adopted the “Amerant” brand across its businesses, with its principal subsidiaries renamed Amerant, and it concluded its initial public offering in December 2018 (Amerant; Amerant).

A Florida bank: digital onboarding, Tampa, and the Houston exit

As an independent bank, Amerant invested in digital onboarding early: in August 2021 it partnered with Alloy to automate identity verification in customer onboarding, with Vice Chairman and CEO Jerry Plush saying the addition would let the bank meet regulatory requirements while making onboarding and underwriting faster and more seamless (Finovate). The bank also raised its South Florida profile in September 2023, when the Florida Panthers announced Amerant Bank as the naming-rights partner for their Sunrise home arena — renamed Amerant Bank Arena — under a multi-year deal whose financial terms were not disclosed (Associated Press).

Geographically, the bank pivoted to Florida. It opened a Tampa loan production office in June 2022 and its first full-service Tampa banking center in February 2024, in the Westshore Business District, with a regional corporate office planned in the same building (Amerant Bank). Then it exited Texas: in April 2024 it agreed to sell its Houston banking operations and six branches to MidFirst Bank, a deal covering about $576 million in deposits and $529 million in loans at announcement (MidFirst Bank). The sale closed on November 8, 2024, at about $573.9 million in deposits and $479.2 million in loans, with Plush saying the decision let the bank focus on accelerating growth in South Florida and greater Tampa (U.S. Securities and Exchange Commission). After the sale, the bank operated 19 banking centers — 18 in South Florida and 1 in Tampa — with over $10 billion in assets (U.S. Securities and Exchange Commission).

What this profile does not claim

• The “largest community bank headquartered in Florida” label is Amerant’s own description (tied to a community-bank definition of under $10 billion in assets); it is attributed, not independently verified.
• This profile covers Amerant Bank, N.A.; the NYSE ticker AMTB belongs to its parent, Amerant Bancorp Inc., and parent-level figures are not presented as bank-level figures.
• IPO share count and price were not verified in a fully-read primary source in this pass, so only the December 2018 IPO completion is claimed.
• Branch counts and asset totals are as of November 2024 per the Form 8-K; later counts were not verified in this pass.
• The parent’s reported mid-2023 move from Nasdaq to the NYSE was not verified in a fully-read source and is not claimed.
