Toyota Motor Corp raised its annual net profit forecast by more than 10 percent to 860 billion yen on strong sales of the Camry sedan and other vehicles in its biggest market the United States, as well as the yen's drop.
The world's biggest-selling carmaker posted a net profit of 99.9 billion yen for the three months to December 31, up 23.5 percent from a year ago when it struggled after natural disasters disrupted its supply chain.
Its third-quarter profit figure was below the average estimate of 143.7 billion yen among seven analysts polled by Thomson Reuters I/B/E/S.
