According to About.com, Judi Evans (Adrienne Kiriakis) and Wally Kurth (Justin Kiriakis) are both off contract as of November 30. There is no confirmation from the publicist team, though the publicists never comment on contracts, and neither party has confirmed. Judi Evans also works at Rose Hills Memorial Park as a sales director and stated on her Facebook page, "So grateful to work at Rose Hills.”
Being off contract does not necessarily mean that they have left the show. It could mean that they will appear less.
