Prior to the 2017–18 season, the Lockport Express relocated to become the Niagara Falls PowerHawks, the Syracuse Stampede relocated to become the Oswego Stampede, and the West Michigan Wolves relocated to become the Lansing Wolves. The Chicago Jr. Bulldogs, Euless Jr. Stars, and L/A Fighting Spirit franchises were sold; the Bulldogs were relocated as the Wausau RiverWolves, the Jr. Stars re-branded as the Mid-Cities Jr. Stars, and the Fighting Spirit re-branded as the Lewiston/Auburn Nordiques. The Cincinnati Thunder, which had already been playing out of Dayton, re-branded as the Dayton Falcons. The Butte Cobras, formerly of the Western States Hockey League (WSHL), purchased the Glacier Nationals franchise in order to join the NA3HL. The schedule was set with 47 teams, however, the Butte Cobras and Billings Bulls would both fold prior to playing a game, while the Dayton Falcons, Nashville Junior Predators, and Jersey Shore Wildcats were also removed from the schedules during the season.
