GM Beat Estimates for U.S. Sales Growth Last Month

General Motors Co. isn’t reporting monthly sales anymore, but maybe it should. The company’s May sales beat analyst estimates -- and all major rivals -- with a gain of 12 percent, said people familiar with the matter.

GM’s sales gain exceeded the average analyst estimate for an 11 percent increase and Fiat Chrysler Automobiles NV’s 11 percent jump. Most carmakers topped expectations, as the economy remains strong and federal tax cuts have given consumers more money to spend.
