Conacher, waived by the Lightning on Wednesday, has appeared in one game with the team this season. The new deal will pay him $700,000 at the NHL level in 2019-20.
The 28-year-old came up through the Lightning organization as an undrafted free agent before being traded to Ottawa in 2013.
He rejoined the Lightning in 2016 on a one-year deal, before signing a two-year contract ahead of the 2017-18 season.
The 5-foot-8 forward had eight goals and 12 points with the Lightning last season.
