Since joining the Stagecoach Group, Stagecoach Strathtay now has an operating area bounded by Aberdeen in the north, Gauldry & Newport-on-Tay to the south and Perth to the west. Before joining Stagecoach, Strathtay operated only as far as Laurencekirk in the north; however, the Montrose depot has acquired some work from Bluebird's Stonehaven depot, including route 24 from Brechin to Stonehaven, route 103 from Laurencekirk to Aberdeen and a handful of School Contracts serving Mackie Academy in Stonehaven.
