Expects to Complete Acquisition Effective April 1, 2020

Brentwood, Tenn. – (March 3, 2020) – Reliant Bancorp, Inc.

“We are very pleased that shareholders of Reliant and First Advantage overwhelmingly voted to approve the proposals related to Reliant’s pending acquisition of First Advantage,” stated DeVan Ard, Jr., Reliant’s Chairman, President and CEO. “The addition of First Advantage will position Reliant as the second largest bank in Montgomery County, Tennessee and the third largest bank in the Clarksville, TN-KY Metropolitan Statistical Area (the “Clarksville MSA”), based on the most recent FDIC deposit market share data. First Advantage’s markets are contiguous to those of recently acquired Community Bank & Trust in the northwest corner of Middle Tennessee. In addition, the First Advantage acquisition will add branches and lending teams in our existing markets in Nashville and Franklin.”

“We are excited about adding the exceptional team at First Advantage Bank to the Reliant family. Based on December 31, 2019 financial data, our combined companies had approximately $3.0 billion in assets, approximately $2.5 billion in deposits and approximately $2.3 billion in loans. In addition, we will have 27 full-service banking offices in Middle Tennessee and Chattanooga. We are positive about our expanded market share in the fast-growing Clarksville MSA and expect the addition of First Advantage to be accretive to Reliant’s earnings in the second half of 2020,” Ard concluded.

Earl Bradley, President of First Advantage, stated, “We are very pleased with the support of First Advantage’s shareholders in approving this transaction. We expect that our customers will benefit from the increased number of banking locations and services available to them after the combination with Reliant. We will have a much stronger network across Middle Tennessee to support our employees, customers and the communities that we serve.”
