BRIGGS & STRATTON CORPORATION REPORTS RESULTS FOR THE

FIRST QUARTER OF FISCAL 2005

Milwaukee, WI October 21, 2004/PR Newswire/-Briggs & Stratton Corporation (NYSE:BGG)

Briggs & Stratton Corporation today announced first quarter consolidated net sales of $439.0 million and a net loss of $1.5 million or $.06 per diluted share. Consolidated net sales increased $107.6 million or 32% over the prior year while net income decreased $5.5 million over the same period a year ago. The primary factor that caused the first quarter results to be less than last year was a $10.0 million ($6.4 million after tax) increase in the reserve for uncollectible receivables caused by the financial difficulties of a customer.

The majority of the $107.6 million net sales increase was due to the inclusion of $79.5 million of sales of our Simplicity Manufacturing, Inc. (“Simplicity”) acquisition, which was completed on July 7, 2004. The remainder of the net sales increase was the result of a mix of shipments that favored higher priced, higher horsepower engines and an increase in generator shipments due to the high number of demand creating weather events.

The first quarter benefited from better engine mix, increased engine production, lower interest expense and higher dividend income. These improvements more than offset cost increases for raw materials and components that continue to be at high levels however, the increase in the allowance for doubtful accounts created a net loss for the quarter. The Simplicity acquisition did not benefit the first quarter because of the accounting treatment required on the acquired inventory.

Engines:

Fiscal 2005 first quarter net sales were $254.1 million, an $18.4 million or 8% improvement over the prior year. This increase is primarily due to a first quarter mix of shipments that favored higher priced, higher horsepower engines. The favorable mix was created by strong summer demand for riding lawnmower equipment and the need for the larger engines used in portable generators.

The loss from operations was $4.7 million, a decrease of $8.7 million from the income reported for the same period a year ago. A favorable mix of engine shipments, price improvement and a significant increase in plant utilization in the first quarter provided positive contributions to income from operations. However, income from operations was lowered between years by the previously mentioned $10.0 million accounts receivable reserve increase and increased raw material and component costs.

Power Products:

First quarter net sales were $222.3 million, a $97.5 million or 78% increase over the same period a year ago. The increase in net sales was the result of having $79.5 million of sales from our Simplicity acquisition and a 30% unit increase in the shipment of generators. These positive trends were partially offset by a 6% decrease in pressure washer unit shipments. Last year’s first quarter generator sales were primarily impacted by the East Coast power grid failure. The unusual level of hurricane activity in this year’s first quarter created a concentrated demand that was capped by product availability.

Income from operations was $5.2 million, a decrease of $3.5 million or 41% from the prior year. The operating income improvement from increased generator volume was offset by lower unit pricing experienced on pressure washer shipments, higher costs for steel and copper and lower utilization of the production capacity. Pressure washer production was approximately 50% lower than last year because of increased inventory levels between years. The Simplicity acquisition negatively impacted income from operations by $.8 million primarily resulting from the application of purchase accounting rules that increased the cost of sales by $4.0 million.

General:

Interest expense is lower in the first quarter of fiscal 2005 because outstanding long-term debt is lower than last year’s level. The effective tax rate is at 36% versus the 32% used in the first quarter last year.

Outlook:

We believe the stronger than anticipated first quarter sales of generators allows us to increase our sales forecast for the Power Products Segment. In addition, as we assess preliminary engine demand and placement, we now believe that engine unit volume could increase by approximately 6% instead of the 3% originally anticipated. Consequently, we now project that consolidated net sales for the year will be approximately 26% higher than last year. The sales of our Simplicity acquisition continue to be projected at $360 million.

Consolidated gross profit margin for the year is currently projected to be 22% to 23%. We have reduced our margin projection to reflect that the higher costs experienced on certain raw materials and components in the first quarter will remain at these levels for the full fiscal year. An incremental 4% price increase on certain powered products, in addition to our initial price increase and our cost reduction initiatives will not fully offset these higher costs.

Consolidated operating expenses are estimated to be between 11% and 12% of net sales. Interest expense is estimated to be $32 million, and other income is projected to be in the $12 to $14 million range. This projection assumes an effective tax rate of 36% for the year, but the American Jobs Creation Act of 2004 could have an impact on our rate going forward. These assumptions result in an annual net income forecast in the range of $150 to $160 million.

We project that second quarter sales will be approximately 28% greater than last year. Operating margins are estimated to be slightly lower than last year due to purchase accounting for Simplicity and net income is forecast to be up about 28% over the same period a year ago.
