General Motors earns its profits overwhelmingly from full-size pickups and SUVs in North America, where Chevrolet Silverado and GMC Sierra command loyal buyers and fat margins. The Ultium battery platform underpins its electric lineup across brands from Chevy to Cadillac, scaled up or down as demand shifts. GM exited most international markets to concentrate capital where it wins, and buybacks have shrunk the share count aggressively. Founded in 1908, the company remains the largest American automaker by domestic sales.
