GM Plans $10 Billion Stock Buyback

General Motors plans to sharply increase cash return to shareholders, as Chief Executive Mary Barra seeks to reassure investors about the health of GM’s core car-making business after setbacks in fledgling pursuits such as electric and driverless vehicles.

The company also said Wednesday it will work to offset higher labor expenses from its new contract with the United Auto Workers and unionized employees in Canada. The contracts will add $1.5 billion next year, rising to $2.5 billion in 2027, higher than analysts had estimated.
