R/GA is closing its spacious Hudson Yards office in New York City as well as its office in downtown San Francisco as part of a larger structuring under CEO Sean Lyons.

Multiple sources confirmed to Adweek that Lyons told the agency the news via email Tuesday night.

As part of the restructuring, R/GA is moving away from its city model in the U.S. and instead implementing a country model with five disciplines powering the business.
