Regions Bank (NYSE: RF) is a publicly-held company based in Birmingham. The company provides retail and commercial banking, trust, securities brokerage, mortgage and insurance products and services. Regions is currently ranked at No. 446 on the Fortune 500 with $6.7 billion in 2019 revenues. It is the 32nd largest bank holding corporation, with $126 billion in assets and a market capitalization of $20 billion. Regions is part of the S&P 500 index. The banking division operates 2,000 branch offices and 2,600 ATMs, and employs 6,200 people in Birmingham, making it the area's largest private-sector employer. Regions has nearly 20,000 employees nationwide.
Regions was founded with the union of First National Bank of Montgomery, the Exchange Security Bank of Birmingham, and the First National Bank of Huntsville on July 13, 1971. The holding company, the first to be chartered in Alabama, was originally named First Alabama Bancshares with $543 million in assets. With a change to regulations enacted in March 1975, it rebranded its 40 locations under the First Alabama Bank nameplate.
In 1986, changes in the Interstate Banking Bill allowed bank holding companies to purchase bank branches outside the state in which they were chartered. First Alabama Bancshares expanded its operations first into Florida, continuing into Georgia, Tennessee and Arkansas. To reflect its growth into a regional company, First Alabama Bancshares changed its name to Regions Financial Corporation and the name of its banking subsidiary to Regions Bank on May 2, 1992.
The 2006 merger of Regions with AmSouth Bank created one of the 10 largest banking corporations in the United States, with assets totaling over $140 billion. After the merger, the combined company moved its headquarters to the Regions Center, formerly known as the AmSouth Center, across 20th Street North from its former headquarters in the Regions Plaza building at 4th Avenue North and 20th Street.
Over the years, Regions has added banking branches in Alabama, Georgia, Tennessee, Florida, South Carolina, Texas, Louisiana, and Arkansas. In addition to the banking subsidiary, Regions Financial operates a mortgage bank, Regions Mortgage, a trust company, and an investment subsidiary, Regions Investment Company, Inc. Later, Resbamen Insurance Company was acquired, further expanding the range of financial services offered by the company. The company sold its subprime lending unit in March 2008 to reduce its exposure to risky mortgages, a prime factor in the poor performance of some Morgan Keegan mutual funds. That same year, Regions obtained a $3.5 billion loan through the Troubled Asset Relief Program (TARP). The loan was repaid in full on April 4, 2012.
In 2014 Regions Bank began reorganizing from geography-based divisions into primary business units, a process termed "Simplify and Grow". The "General Bank", headed by John Owen, serves retail, wealth management and small business customers; and a "Corporate Bank", headed by John Turner, serves mid-sized and large corporate clients. Regions also placed its wealth management practice into a separate unit within the company. In 2018 Regions sold its insurance group to BB&T Insurance Holdings.

- January 24, 2004: A $5.9 billion dollar merger with Memphis-based Union Planters Bank was announced. This merger was noteworthy (at least among large banks) for the fact that Regions, the acquiring bank, did not pay a premium above the currently trading stock price of Union Planters shares. Union Planters Bank, however, was to receive an equal number of board seats within the newly formed bank. This, coupled with the announcement that Jackson W. Moore, the chairman, president, and CEO of Union Planters Bank was to become the CEO of the newly formed bank (a position formerly held by Carl E. Jones) one year post merger, led many to call this marriage a 'merger of equals' despite the fact that Regions Bank was half again larger than Union Planters at the time of the announcement. Shortly before assuming the duties of CEO of Regions Bank in 2005, Moore suffered a stroke, but was still able to assume his new post upon recovery.

Upon completion of the merger, Regions Financial became the nation's 8th largest bank with total assets of nearly $140 billion and approximately 2,000 branches.
