On December 13, 2020, TCF management announced an all-stock merger with Columbus, Ohio-based Huntington Bancshares. Under the terms of the merger agreement, the bank would retain the Huntington name and have headquarters in both Columbus, for retail operations, and Detroit for business operations. TCF shareholders would receive 3.0028 HBAN shares for each share of TCF. TCF's stock reacted positively to the news, trading up ~7% at the market open on the Monday following the announcement. On May 26, 2021, the Department of Justice mandated that TCF Bank sell 13 branches in Michigan. Horizon Bank purchased these branches in September 2021. Regulators gave final approval for the merger and it closed on June 9, 2021.
