Volvo's net profit for the July-September period totalled 3.89 billion kronor ($595 million), weaker than the 3.93 billion kronor expected by analysts polled by Dow Jones Newswires but up from the 2.85 billion kronor Volvo posted in the same period a year ago.
The group's sales rose to 73.3 billion kronor, above forecasts of 71.2 billion kronor and far higher than the 63.9 million kronor reported a year ago. Adjusted for currency fluctuations, the year-on-year sales increase was 22 percent.
Operating income improved to 5.8 billion kronor from 4.9 billion kronor a year ago, corresponding to an operating margin of 7.9 percent.
The group said it had noted a "slight slowdown" in Europe recently, and was therefore "preparing to reduce manufacturing rates in the European production
system in the beginning of next year."
While it expected the total market for heavy trucks in Europe this year to be in line with its previous forecasts of around 240,000 trucks, it predicted a 10-percent decline in 2012 but noted that the situation was difficult to assess given the "uncertain macroeconomic situation".
In North America, Volvo saw the opposite trend: it reduced its forecast for the overall market from 230,000-240,000 heavy trucks to 210,000 this year, but predicted a 20-percent increase in demand next year.
"The reduction this year is primarily due to the production ramp-up for the industry as a whole taking longer than we anticipated," Volvo said.
"Our positive view of demand in 2012 is based primarily on the fact that it is becoming uneconomical to keep parts of the old truck fleet in operation compared with the new trucks we launched in 2010 which have significantly lower fuel consumption," it said.
Meanwhile, the company saw rising demand in Japan "as reconstruction begins following the earthquake and tsunami earlier this year."
Volvo's share price was down by 0.57 percent to 78.80 kronor on the Stockholm stock exchange in early trading, on a market down by 0.10 percent.
