REGAL BELOIT REPORTS FOURTH QUARTER AND
FULL YEAR FINANCIAL RESULTS

•		Quarterly Sales Increased 20.0% Including Sales From Six Acquisitions Closed In 2010
•		Strong Operating Cash Flow

February 2, 2011 (Beloit, WI): Regal Beloit Corporation (NYSE: RBC) today reported financial results for the fourth quarter and the fiscal year ended January 1, 2011. Net sales for the fourth quarter ended January 1, 2011 were $555.7 million, an increase of 20.0% compared to $463.3 million for the fourth quarter ended January 2, 2010. Diluted earnings per share for the fourth quarter 2010 were $0.65 compared to $0.90 for the fourth quarter 2009. For the full year 2010, sales were $2,238.0 million an increase of 22.5% compared to $1,826.3 million for 2009. Full year 2010 diluted earnings per share were $3.84 compared to $2.63 per share in 2009.

“In line with our updated guidance, HVAC sales softened in the fourth quarter,” commented Mr. Henry Knueppel, Chairman and Chief Executive Officer. “Additionally, we faced continued inflationary pressure on input costs, especially costs for copper. We implemented price increases to offset the inflation; however, they could not be implemented fast enough to prevent margin erosion given the severity of the commodity cost increase.”

“As we look at the full year we are pleased to report EPS growth of 46% to $3.84 per share,” continued Mr. Knueppel. “Sales for 2010 grew 22.5% as a result of strong organic growth combined with the benefit from the six acquisitions that closed in 2010.”

Sales for the fourth quarter 2010 included $56.8 million of incremental sales from the six businesses acquired in 2010 (the “acquired businesses”). Sales growth was driven by increased demand in nearly all end markets including strong demand for energy efficient products. Full year 2010 included $119.5 million of incremental sales from acquired businesses.

In the Electrical segment, sales increased 18.5% in the fourth quarter 2010 compared to the fourth quarter 2009, including $47.1 million of incremental sales from the acquired businesses.

Residential HVAC motor sales increased 1.3% in the fourth quarter 2010 as compared to the fourth quarter 2009. Driven by improving end markets and higher sales in North America, commercial and industrial motor sales for the fourth quarter 2010 increased 12.5% compared to the fourth quarter 2009. Global generator sales increased 15.7% for the fourth quarter 2010 compared to the fourth quarter 2009.

Sales in the Mechanical segment increased 33.1% in the fourth quarter 2010 compared to the fourth quarter 2009, including $9.7 million of incremental sales from the acquired businesses. This increase was driven primarily by improvements in later cycle end markets. Full year 2010 Mechanical segment sales increased $47.4 million, or 25.1% compared to fiscal year 2009, including $26.9 million of incremental sales from the acquired businesses.

One of the Company’s key strategies is to grow international operations.

For the full year 2010, sales to regions outside the United States were 31.6% compared to 26.9% for the full year 2009.

INCOME FROM OPERATIONS

		(In thousands)
		Three Months Ended								Fiscal Year Ended
		Jan. 1, 2011				Jan. 2, 2010				Jan. 1, 2011				Jan. 2, 2010
Income from Operations		$	38,288			$	53,542			$	237,735			$	159,520
As a percentage of net sales			6.9	%			11.6	%			10.6	%			8.7	%
Income from Operations by Segment:
Electrical segment		$	33,016			$	51,860			$	210,231			$	144,901

As a percentage of net sales			8.6	%			3.6	%			11.7	%			7.8	%

For the fourth quarter 2010, income from operations declined 28.5% compared to the fourth quarter 2009 principally due to inflation not recovered by pricing actions and a $28.4 million change in LIFO expense. The fourth quarter 2010 included LIFO expense of $13.4 million reflecting the continued increase in costs for commodity inputs. By comparison, the fourth quarter 2009 included a LIFO benefit of $15.0 million from our actions to reduce inventory levels. For the fourth quarter 2010, operating expenses increased due to an incremental $14.3 million of operating expenses related to the acquired businesses and an incremental $2.6 million of acquisition related expenses.

For the full year 2010, income from operations improved, driven by sales volume leverage and productivity, but was substantially offset by commodity cost inflation in excess of price increases and the costs associated with supply chain disruptions in the second and third quarters of 2010.

Net interest expense for the fourth quarter 2010 was $4.5 million, consistent with the fourth quarter 2009. The effective tax rate for the fourth quarter 2010 was 22.7% compared to 27.7% for the fourth quarter 2009. The decrease in the effective tax rate for the quarter was primarily driven by the global distribution of income and the retroactive reinstatement in the United States of the research and development tax credit.

Net income attributable to Regal Beloit Corporation for the fourth quarter 2010 was $25.2 million, a decrease of 27.2% compared to $34.7 million for the fourth quarter 2009. Fully diluted earnings per share for the fourth quarter 2010 were $0.65 compared to $0.90 for the fourth quarter 2009. For the full year ended January 1, 2011, net income attributable to Regal Beloit Corporation was $149.4 million, an increase of 57.2% compared to $95.0 million for the full year 2009.

Net cash provided by operating activities was $26.8 million for the fourth quarter 2010 and $175.4 million for the full year 2010, in excess of net income attributable to Regal Beloit Corporation for those periods. Cash and investments totaled $230.8 million at January 1, 2011.

“Looking back on the year, I am proud of our team’s many accomplishments, along with our performance improvements. We also closed on six strategically important acquisitions and we are successfully integrating those businesses into our company,” continued Mr. Knueppel. “Looking forward into 2011, we are optimistic about our ability to continue our growth strategy by developing and producing new and innovative, energy efficient products for our customers. Our optimism is tempered by the continued increase in commodity input costs that will pressure our operating margins. We are also excited about closing on the purchase of the Electrical Products Company of A. O. Smith and the opportunity to welcome its employees to the Regal Beloit team. We expect the first quarter to show seasonal improvement over the fourth quarter and to see improved contributions from our new acquisitions. Accordingly, we are projecting first quarter diluted earnings of $0.92 to $0.98 per share.”
