BRIGGS & STRATTON CORPORATION REPORTS RESULTS FOR

THE SECOND QUARTER OF FISCAL 2010

MILWAUKEE, WI January 14, 2010/PR Newswire/-Briggs & Stratton Corporation (NYSE:BGG)

Briggs & Stratton today announced second quarter fiscal 2010 consolidated net sales of $393.0 million and consolidated net income of $3.0 million or $0.06 per diluted share. The second quarter of fiscal 2009 had consolidated net sales of $477.5 million and consolidated net income of $3.2 million or $0.06 per diluted share. Consolidated net sales decreased $84.5 million between years, with both reporting segments experiencing lower sales, primarily the result of lower unit volumes. Consolidated net income was fairly consistent between years despite the sales decline. This result reflects better margins caused by lower manufacturing costs and lower engineering, selling, general and administrative costs.

For the first six months of fiscal 2010, the company had consolidated net sales of $717.7 million and a consolidated net loss of $5.7 million or $0.12 per diluted share. For the same period a year ago, consolidated net sales were $935.6 million and consolidated net income was $1.2 million or $0.02 per diluted share. The decrease in the first six months’ consolidated net sales of $217.9 million was attributable to both reporting segments experiencing lower sales, primarily the result of lower unit volumes. Consolidated net income declined by $6.9 million between years resulting from lower volumes of product both shipped and manufactured, offset in part by manufacturing and operating costs that were lower than in the same period a year ago.

Engines:

Fiscal 2010 second quarter net sales were $274.3 million versus $339.3 million for the same period a year ago, a decrease of 19%. The decrease resulted primarily from a 15% decrease in engine unit shipments between quarters driven by lower shipments for lawn and garden applications as some OEMs are delaying deliveries of engines to control their inventory investment ahead of an uncertain market environment for the spring of 2010. In addition, engine requirements for portable generators were down due to the lack of any significant weather events and engine shipments for snow thrower applications were down because of shifts in placement.

Net sales for the first half of fiscal 2010 were $484.7 million versus $597.9 million in the prior year, a 19% decrease. This decrease reflects an 18% decrease in engine unit shipments between years. The first six months sales decline in engine unit volume resulted from primarily the same reasons discussed for the second quarter in addition to light first quarter sales of engines because 2009 summer retail demand for lawn and garden equipment was soft and did not generate the same level of engine reorders that occurred in the prior year.

The second quarter of fiscal 2010 had income from operations of $18.0 million versus $22.0 million from the same period a year ago. The decrease of $4.0 million in income from operations reflects the impact of a 19% revenue decrease and a 6% decrease in production volume offset by lower manufacturing and operating costs, resulting primarily from lower commodity costs and planned cost savings initiatives.

Income from operations for the first half of fiscal 2010 was $12.1 million, a $4.4 million decrease from income from operations of $16.5 million for the same period a year ago. The decrease of $4.4 million in income from operations was the result of a 19% revenue decrease and a 10% decrease in production volume offset by the same factors described in the quarter.

Power Products:

Fiscal 2010 second quarter net sales were $156.6 million, a $35.4 million decrease from the $192.0 million in the same period a year ago. The lower net sales were primarily the result of a decrease in shipments of portable generator product. Replenishment demand that occurred because of major weather events last year was not required in the current year due to a lack of weather events. In general, all lawn and garden product volumes were

less than those in the same period a year ago, except for stronger snow thrower shipments. All levels of the lawn and garden distribution channel appear to be managing to lower inventory levels ahead of the spring of 2010 retail season.

Net sales for the first six months of fiscal 2010 were $320.2 million, a $127.4 million decrease over the same period a year ago. The sales decline was primarily the result of a decrease in sales of portable generators due to no hurricanes making landfall in the United States in the first half of fiscal 2010. Other than a small increase in pressure washer shipments, the other product offerings in this reporting segment had volume declines between years.

The loss from operations for the second quarter of fiscal 2010 was $4.5 million, an improvement of $4.1 million over the loss for the same period a year ago. The improvement in the loss from operations for the quarter was the result of lower manufacturing costs, primarily related to lower commodity costs and planned cost saving initiatives. These improvements were partially offset by lower sales, lower production volumes and $1.7 million of expenses associated with the previously announced closing of the Jefferson, Wisconsin manufacturing facility.

The loss from operations for the first six months of fiscal 2010 was $0.9 million, a $5.1 million improvement over the loss from operations for the same period a year ago. The improvement in the loss from operations between years resulted from the same factors as described for the quarter and was also offset year to date by an unfavorable mix of lawn and garden product shipments. Through the first six months of fiscal 2010, costs related to the closure of the Jefferson, Wisconsin facility were $3.1 million.

General:

Interest expense was lower in the second quarter and first six months of fiscal 2010 because of lower average borrowings. The second quarter and year to date fiscal 2010 effective tax rates are at 29% and 39%, respectively, versus the 30% and 155% used in the same respective periods last year. The difference between the effective tax rates for the six month periods was due to the impact of higher levels of discrete items related to foreign dividends in fiscal 2009 compared to fiscal 2010.

Outlook:

The company continues to project that fiscal 2010 net income will be in the range of $40 to $50 million or $0.80 to $1.01 per diluted share. Consolidated net sales are projected to be approximately 6% lower between years primarily due to the absence of hurricane related sales of portable generators, selected price reductions to reflect projected lower commodity costs and lower engine shipments to Europe for lawn and garden applications. Production levels for substantially all products are planned to be lower in fiscal 2010 to decrease our investment in working capital. Operating income margins are projected to be in the range of 4.0% to 5.0%, and interest expense and other income are forecasted at $27 million and $5 million, respectively. The effective tax rate for the full year is projected to be in a range of 31% to 34%.
