Polaris Industries Inc.'s (NYSE:PII) third-quarter earnings rose 39 percent as all of its product lines saw double-digit percentage sales increases.

The company also raised its full-year earnings estimate to between $4.32 and $4.37 a share on 19 percent to 20 percent sales growth. Its previously increased July forecast was for per-share earnings of $4.05 to $4.15 on 14 percent to 17 percent sales growth.

The maker of all-terrain vehicles, like snowmobiles, has seen its revenue and profits increase by double-digit percentages for more than two years, thanks in part to strong demand for its off-road vehicles and motorcycles in North America.

Polaris reported a profit of $94.3 million, or $1.33 a share, up from $67.6 million, or 95 cents, a year earlier. Sales jumped 21 percent to $879.9 million.

Analysts polled by Thomson Reuters had most recently forecast earnings of $1.20 a share on revenue of $831 million.

Gross margin improved to 29.5 percent from 28.3 percent.

Snowmobiles sales climbed 21 percent to $114.9 million while on-road vehicle sales jumped 78 percent to $63.4 million. Sales of parts, garments and accessories increased 14 percent to $128.6 million.
