In December 2007, he co-founded the Breaux-Lott Leadership Group, a "strategic advice, consulting, and lobbying" firm together with former Louisiana Senator John Breaux. The firm was later acquired by law and lobbying firm Patton Boggs, now Squire Patton Boggs following the June 2014 merger with Squire Sanders. In September 2014, lobbyist filings revealed that Lott was contracted to advocate on behalf of Gazprombank, a Russian majority state-owned bank targeted with sanctions over the 2014 pro-Russian unrest in Ukraine. Lott was fired by Squire Patton Boggs in June 2020; no explanation was provided for his departure. Lott serves on the board of directors of Airbus North America.
