Regal Beloit Corporation Announces First Quarter 2013 Financial Results; Diluted Earnings per Share In Line With Guidance

BELOIT, WI - Regal Beloit Corporation (NYSE: RBC) today reported financial results for the first quarter2013. Net sales for the first quarter2013 were $778.2 million compared to $807.9 million for the first quarter of 2012. Net Income for the first quarter 2013 was $50.7 million compared to $49.9 million for the first quarter of 2012. Diluted earnings per share for the first quarter2013 were $1.09 compared to $1.16 for the first quarter of 2012, reflecting the higher share count.

“In the first quarter of 2013, Regal's end markets were mixed. While the U.S. residential market grew in line with expectations, the U.S. commercial and industrial markets did not perform as well as we had expected earlier in the year. Our North American HVAC sales were up 3.5% in the quarter and sales in our Unico business remained strong," said Regal Chairman and CEO Mark Gliebe. "In spite of the top line challenges the teams executed well on our synergy and simplification initiatives, allowing us to maintain operating margins," continued Mark Gliebe.

The effective tax rate for the first quarter 2013 was 23.2% compared to 26.3% for the first quarter 2012. The decrease was driven primarily by completion of the tax integration of the EPC acquisition and the retroactive reinstatement of the R&D tax credit.

Interest expense was down $1.2 million compared to the first quarter 2012 due to a decline in average outstanding debt.

For the first quarter 2013, net cash provided by operating activities was $66.0 million. For the first quarter 2012, net cash provided by operating activities was $68.5 million. Cash on hand at March 30, 2013 was $411.9 million, an increase of $36.6 million from year end 2012. For the first quarter 2013, free cash flow* represented 91.7% of net income.

“As we look to the second quarter, sluggish demand in our North American commercial and industrial markets is impacting both our electrical and mechanical segments. To a lesser extent, we are anticipating unfavorable market dynamics in the HVAC channel. We expect diluted earnings per share for the second quarter of 2013 to be $1.17 to $1.25. Adding back $0.02 of restructuring charges, adjusted diluted earnings per share are expected to be $1.19 to $1.27,” continued Mark Gliebe.

NON-GAAP MEASURES

Unaudited

(Dollars in Millions Except Per Share Data)

We prepare financial statements in accordance with accounting principles generally accepted in the United States (GAAP).  We also disclose adjusted diluted earnings per share (EPS), adjusted gross profit, adjusted gross profit as a percentage of net sales, adjusted income from operations, free cash flow and free cash flow as a percentage of net income attributable to Regal Beloit Corporation (collectively, “non-GAAP financial measures”). We use these measures in our internal performance reporting and for reports to the Board of Directors.  We also periodically disclose certain of these measures in our quarterly earnings releases, on investor conference calls, and in investor presentations and similar events. We believe that these non-GAAP financial measures are useful measures for providing investors with additional insight into our operating performance. This additional information is not meant to be considered in isolation or as a substitute for our results of operations prepared and presented in accordance with GAAP.  Free cash flow is defined as net cash provided by operating activities less additions to property, plant and equipment.
