Truist is taking a new approach to integrating and upgrading digital technology since its formation from the merger of SunTrust and BB&T banks, such as building new channels for mobile and online banking. Truist is also embracing a "hybrid cloud" structure and created a data utility process that it calls a "digital straddle." "Ours is probably the first and largest merger in what I would call the digital era in banking, and that forced us to think about challenges like this," said Chief Information Officer Scott Case.

Longtime CEOs at banks across the US, including Truist's Kelly King, BOK Financial's Steven Bradshaw and German American Bancorp's Mark Schroeder, are stepping aside to hand over control to their successors. Here is a roundup of nine new CEOs who are taking the helms at their banks.

Truist's new CEO Bill Rogers said one of the bank's top priorities for sustainable growth is deploying capital by making acquisitions, with plans to spend $1 billion to $2 billion early next year. This comes after the bank spent $1 billion on Constellation Affiliated Partners and $2 billion on Service Finance.

Truist plans to onboard customers to a smartphone application that leverages the past success of fintech companies, said the bank's chief digital and client-experience officer Donta Wilson. The bank has been testing its app and found areas that need addressing, Wilson said.
