Larrieu MediaRelations@amerantbank.com (305) 441-8414 Amerant Shareholders Approve Clean-Up Merger that Will Simplify its Capital Structure CORAL GABLES, FL (Nov. 15, 2021) – Amerant Bancorp Inc. (NASDAQ: AMTB and AMTBB) (the “Company” or “Amerant”) announced today that its shareholders approved a clean-up merger pursuant to which a subsidiary of the Company will merge with and into the Company (the “Merger”). The Merger will simplify Amerant’s capital structure by automatically converting shares of the Company’s Class B common stock into the Company’s shares of Class A common stock. Under the terms of the Merger, each outstanding share of Class B common stock will be automatically converted to 0.95 of a share of Class A common stock without any action on the part of the holders of Class B common stock; however, to the extent any shareholder, together with its affiliates, would own more than 8.9% of the outstanding shares of Class A common stock following the Merger, such holder’s shares of Class A common stock or Class B common stock, as the case may be, will be converted into shares of a new class of Non-Voting Class A common stock, solely with respect to holdings that would be in excess of the 8.9% limit. The Company currently intends the Merger to be effective on Thursday November 18th at 12:01 a.m. Eastern Time. Following the completion of the Merger, only the Company’s
shares of Class A common stock will trade on the NASDAQ under the symbol “AMTB”. The Company expects that Wednesday November 17, 2021 will be the last day of trading of its shares of Class B common stock on the NASDAQ. “We are pleased to announce that our Class A and Class B shareholders were supportive of the view held by our Board and management regarding the benefits of having a single class of publicly traded common equity” stated Jerry Plush, Vice Chairman and CEO. “We can now focus on seeking alternatives to reduce our total cost of capital by optimizing its composition and by evaluating other ways to increase returns to our shareholders.” Cautionary Notice Regarding Forward-Looking Statements This press release contains “forward-looking statements” within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934, including statements regarding the Merger, as well as statements with respect to the Company’s objectives, expectations and intentions and other statements that are not historical facts.
