Franklin Financial Network Inc., Franklin Synergy Bank and Civic Bank & Trust on Sept. 29 again postponed their merger termination date.

The Tennessee-based companies may terminate the deal if the merger does not close on or before July 1, 2018.

It may also be terminated if Franklin Financial fails to provide evidence that it submitted the merger application with the Federal Reserve on or before Nov. 15, or 10 days after the regulator notifies Franklin Synergy it may file the application, whichever is earlier.

In addition, Nashville-based Civic may terminate the agreement if the regulator decides the parties may not file the application.

The termination date had been postponed twice before — first to March 31, then to Sept. 30. The merger was announced in December 2015.
