Fourth quarter net income of $43.9 million, increased 21% from $36.2 million in the fourth quarter 2008, resulting in record earnings per diluted share of $1.31, up 18% from the prior year period

Off-Road vehicles (“ORV”) sales during the fourth quarter 2009, which includes sales of both core ATVs (all-terrain vehicles) and RANGER™ side-by-side vehicles, decreased 12 percent from the fourth quarter 2008. This decrease reflects the ongoing weakness in the consumer retail environment, more dealers operating under the new Max Velocity Program (“MVP”), which inherently requires lower dealer inventory levels, and Polaris’ continued commitment to helping our dealers reduce their core ATV inventory. North American dealer inventories of ATVs were down significantly at year end 2009, declining 35 percent when compared to 2008 levels. North American retail sales for ORVs increased in the single digits percentage range for the 2009 fourth quarter with side-by-side retail sales increasing in the mid-teens and core ATV retail sales decreasing in the mid-single digit range for the quarter. The improvement in the retail sales trends is an indication of the acceptance in the marketplace of the Company’s new product introductions in recent years and market share gains. An example of the Company’s continued aggressive new product development is the recent introduction of the world’s first 4-seat sport side-by-side, the new Robby Gordon Edition RZR 4 released in January 2010. Sales of ORV to customers outside of North America increased 21 percent in the fourth quarter 2009, when compared to the fourth quarter 2008, primarily due to the weak US dollar and positive mix benefit as more higher priced side-by-side vehicles were shipped during the 2009 fourth quarter compared to the prior year.
