A Stamford office tower formerly occupied by the Charter Communications’ headquarters has been sold to a pair of investors for $72 million.

George Comfort & Sons and AVG Partners acquired the 508,043-square-foot building at 400 Atlantic St., which is 30 percent leased.

Charter vacated the 14-story building after relocating to its newly-completed headquarters at 400 Washington Boulevard in 2021.

CBRE’s Jeffrey Dunne, Steven Bardsley, Jeremy Neuer, Travis Langer and Meredith LaPier represented seller Spectrum Stamford LLC, a real estate entity managed by Charter Communications.

“Stamford has transformed from a predominantly FIRE sector economy, to be much more industry diversified with 89 percent of Stamford’s top 25 employers being in other sectors,” Dunne said in a statement.

CBRE Institutional Properties currently is marketing 33 Riverside Ave., a 91-percent leased, 42,432 square-foot waterfront property in Westport and 710 Bridgeport Ave., a 452,414 sq. ft., fully-leased industrial building in Shelton.
