Sources said the actresses are now "essentially on par" with Gubler.
Vangsness, Cook and Gubler have been with "Criminal Minds" since Season 1, while Mantegna joined in Season 3.
Vangess told TMZ in May that she was considering leaving the show if she didn't get a pay bump.
"That's the way it works, sadly," she said. "I feel so uncomfortable about it and so sad. [Not getting a raise] would be telling me that my value isn't what I thought it was. In that case, I need to go get another job."
