Toyota Motor Corp. reported a 39 percent slide in quarterly profit but raised its full-year forecasts for earnings and car sales amid booming business in Asia and other emerging markets.

The results show a mixed picture for the world's biggest automaker, which is enjoying good sales in high-growth markets in Asia, Africa and South America while facing lingering worries about quality lapses in the key U.S. market.

Toyota reported Tuesday a net profit of ¥93.63 billion for the third quarter, down from ¥153 billion a year earlier. Quarterly sales declined 11.7 percent to ¥4.673 trillion.
