Source: NWSLsoccer.com For transfers in, dates listed are when the Reign FC officially signed the players to the roster.

Transactions where only the rights to the players are acquired (e.g., draft picks) are not listed, and amateur call-ups are not considered official signings either.

For transfers out, dates listed are when the Reign FC officially removed the players from its roster, not when they signed with another club.
