YOKOHAMA, Japan — Nissan, the Japanese automaker lashed by slowing growth abroad and management scandals at home, reported on Tuesday the latest bad news in a very difficult year: Its profit has continued tumbling, and the situation is expected to get worse.

The automaker said its net income fell 54.8 percent in the last quarter, to 59 billion yen, or about $540 million, from the same time last year. Its revenue fell 6.6 percent in the same period.

Nissan also reduced its profit forecast for the fiscal year that will end in March by 35 percent, to ¥110 billion. Vehicle sales, too, are expected to trail previous expectations by more than 5 percent, it said. The full-year dividend, which had been projected at ¥ 40 per share, could be revised, Nissan said, “following internal discussion.”

The results show the long path ahead for Nissan as it tries to simultaneously navigate an industrywide slump in global auto sales and emerge from a damaging series of events that began a year ago with the detention of its leader at the time, Carlos Ghosn, on suspicion of financial wrongdoing.
