Southern Bank has served the financial needs of America’s Heartland for over 130 years, making us one of the oldest financial institutions headquartered in the region. We were originally chartered in 1887 as a mutual institution that was owned by its depositors. Our original founders deposited $100,000 in the Poplar Bluff Loan and Building in order to provide financing to help people buy homes. The name was chosen to symbolize our original purpose.

Our Company’s assets grew slowly from $100,000 at its founding to $950,000 on December 3, 1951, when Federal Savings and Loan Insurance Corporation insured our deposits. Afterward, we started an impressive period of growth in which assets would increase to $23 million at December 31, 1969. The next phase of our growth was partially due to expansion into neighboring communities. On April 11, 1969, we opened our first branch in Dexter, Missouri, followed soon by other branches. In 1982, we acquired an office in Van Buren, Missouri. In 1975, the institution changed its name to Southern Missouri Savings and Loan.

On April 13, 1994, we completed a conversion from mutual ownership to a publicly traded stock company. Our stock trades on the NASDAQ Global Market under the symbol “SMBC”. At January 1, 2000, the Bank’s assets were $221 million. Between 2000 and 2008, we added an additional six branches in Southeast Missouri.

In 2009, the Bank added four branches in and around two great Arkansas communities: Jonesboro and Paragould. Following the acquisition of the four Arkansas locations, the Bank’s assets totaled $511 million.

2013 brought another year of growth. A second branch was built in Jonesboro, Arkansas, a new building was built for the Searcy, Arkansas branch, as well as the acquisition of 3 branches in Thayer, Alton and West Plains, Missouri. In late 2013, Southern Bank announced the agreement to merge with Citizens State Bank of Bald Knob, Arkansas. That transaction was complete in early 2014. Also in early 2014, Southern Bank announced its intent to merge with Peoples Bank of the Ozarks. That transaction was completed on December 8, 2014.

In June 2017, the bank completed the aquisition of Capaha Bank. This acquisition included six branches, three of which are located in Cape Girardeau County in Southeast Missouri, along with three branches in Alexander and Union counties in Southern Illinois.

In March 2018, the acquisition was completed with Southern Missouri Bank of Marshfield, with Southern Bank’s total assets equaling $1.9 billion.

The Bank completed the acquisition of First Commercial Bank in December 2018. Seven locations were added to Southern Bank. 

The most recent acquisition was completed in May 2020 with Central Federal Savings and Loan in Rolla, Missouri. The combined company now operates 48 total locations in Missouri, Arkansas, and Illinois.

Assets total $2.4 billion as of March 31, 2020.
