The newspaper, citing unidentified people familiar with the matter, said Monday that talks are at an advanced stage, and an announcement could come as early as this week.
OfficeMax reports its fourth-quarter results on Thursday, while Office Depot is expected to report results next week. Representatives of both companies declined to comment on merger talks.
Boca Raton, Fla.-based Office Depot has about 1,675 stores worldwide, mostly in the U.S. and Canada. OfficeMax, based in Naperville, Ill., has about 900 stores in the U.S. and Mexico. If the two companies merged, they could close stores that compete against each other, as well as reduce costs.
