Diamond Bank Plc began operating on the 21st of March, 1991. The bank had earlier been incorporated on the 20th of December, 1990.

In February 2001, Diamond Bank became a universal bank and in January 2005, following a highly successful private placement share offer which substantially raised the Bank’s equity base, Diamond Bank became a public limited company.

The bank also has a strong Corporate Banking offering that is helping to fuel growth across Nigeria through supporting businesses, redefining the country’s 21st-century economy. It serves over 150,000 businesses of varying size across diverse sectors including Corporate clients as well as MSME (Micro Small and Medium-Scale Enterprises), for which it provides value-adding banking solutions.

With a primary listing on the Nigerian Stock Exchange and GDRs on the London Stock Exchange, Diamond Bank’s footprints extend beyond Nigeria. It launched its first non-African subsidiary, Diamond Bank, UK, in 2013. As of January 2016, the bank operated over 271 branches of the group.
